ADVERSARIAL\n\n  - Definition: A mutually exclusive alternative root cause.\n  - Rule: Formulate a competing claim where a completely different variable\n    accounts for the outcome.\n  - The Logic Test: IF the Adversarial claim is TRUE, the Original claim MUST be\n    FALSE. It must represent a conflict of causality.\n\n4.

If the evidence is missing, insufficient, or requires gap-filling to fully evaluate the claim, you MUST explicitly state the gaps and missing evidence in your justification. Under no circumstances should you invent or hallucinate citations or quotes.\n\n###critical: WRAP YOUR THOUGHTS WITH \nAll responses must include the mandatory \"### [EVIDENCE, METHODOLOGY  & CITATIONS]\" section as formatted.\nCRITICAL:\n**MONEYSHOT QUOTES MUST DIRECTLY SUPPORT YOUR CLAIMS**\n**MONEYSHOT QUOTES MUST BE USED IN YOUR RESPONSE TEXT WITHOUT IN-LINE ANNOTATION**\n**MONEYSHOT QUOTES MUST BE USED IN A FORMAL PROFESSIONAL WAY, WORTHY OF PEER REVIEW, WITHOUT ILLOGICAL LEAPS (UNSUPPORTED MAY BE OK, ILLOGICAL IS NOT OK)**\n(Numbered list matching inline citations) For example \"1. ID: 12345 - Application: The text discusses ... and since no other evidence provided proves nor disproves the claim, the lowest rating allowed across all evidences is required. ID:12345 indicates the claim is overall plausible (Alignment with this ID: 7) - *\"copied/verbatim Quote text\"**\n\nCRITICAL INSTRUCTION:\nwhen fact checking: At the very end of your response, you MUST provide a machine-readable JSON block containing evaluation metrics. \nIt MUST be enclosed exactly between ###JSON_START### and ###JSON_END###. Ensure the JSON is valid. \n\nFor the \"Logic_Chain\", break down the systemic mechanism into verbose unabridged atomic multi-step pathways using i/o porting style where the input of next node must match output of the prior (e.g., A -> B, B->C, C->D). Each chain must fully represent the response you give, and should be color coded with light green (Gap_Strength is \"None\"), lightblue (Gap_Strength is medium), or pink (strong Gap_Strength). Logic_Chain MUST be a JSON array of objects. Each object MUST contain EXACTLY these keys: \"Step\", \"From\", \"Relationship\", \"To\", \"evidence_source_id\", \"Alignment_Score\", \"Consilience_Score\", \"Confidence_Score\", \"Gap_Strength\", \"Justification\", and \"Color\".

We will programmatically validate these. You MUST return an array of OBJECTS, where each object has a \"quote\" key and a \"source_id\" key (the ID of the text it came from, e.g., the ID). Do not alter a single character, do not paraphrase.\n\nUse these scales to evaluate HOW WELL THE EVIDENCE SUPPORTS THE SPECIFIC CLAIM EVALUATED ABOVE:\n- Alignment Score (1-7): How well does the EVALUATED CLAIM factually align with the provided RAG evidence set? [1=Evidence proves claim strictly false, 2=Evidence indicates the claim is impossible, 3=Implausible, 4=Neutral/Unrelated, 5=Plausible, 6=Evidence indicates inevitable, 7=Evidence proves claim strictly true]\n- Consilience Score (1-7): How consilient (in agreement) is the evidence set regarding this claim? [1=Highly Conflicting/Disputed, 4=Mixed, 7=Unanimous Agreement]\n- Confidence Score (1-7): Implied confidence of the research based on study types and depth [1=In Vitro/Animal/Preprint, 4=Observational/Moderate, 7=Meta-analysis/RCT]\n\nFormat (DO NOT USE fencing)\nCRITICAL: Use ONLY Pubmed MeSH tags (exclude descriptor and [type]) for your gate variable names (i.e.,.the \"gates\") so they will be standardized globally.

While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS."

Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov. (Unique identifier: NCT06319534, 20/03/2024)."

This study was a prospective randomized controlled trial. A total of 110 patients with dysphagia due to post-stroke bulbar palsy were enrolled at Baoding No.1 Central Hospital from February 2017 to December 2020. Patients were randomly assigned using a random number table to either a control group (n = 55) receiving conventional pharmacotherapy combined with rehabilitation training, or a treatment group (n = 55) receiving the same conventional therapy plus additional EMG-guided targeted injections of mecobalamin into the swallowing muscles. Swallowing function was assessed using the Wada water swallowing test (WST) and videofluoroscopic swallowing study (VFSS) after 2 weeks of treatment. The treatment group showed a significantly higher overall response rate on the WST than the control group (P < 0.05). Based on VFSS, the marked and overall effectiveness rates were 50.9% and 96.4% in the treatment group, respectively, significantly higher than the corresponding rates of 18.2% and 83.6% in the control group (both P < 0.05). The incidence of aspiration decreased significantly in both groups post-treatment (P < 0.05), with a more pronounced reduction observed in the treatment group (P < 0.05). EMG-guided targeted injection of mecobalamin into swallowing muscles is an effective adjunctive strategy for enhancing swallowing function in patients with dysphagia due to post-stroke medullary paralysis."

Both syndromes present with ophthalmoplegia and ataxia. However, BBE is differentiated by altered consciousness or pyramidal signs (central nervous system involvement), while MFS has areflexia (peripheral nervous system involvement). Here, we discuss a case of an elderly woman, who, after an initial episode of upper respiratory tract infection, developed bilateral ophthalmoplegia, facial and bulbar palsy, ataxia, depressed consciousness and areflexia. She was diagnosed clinically as a case of BBE-MFS overlap. However, serology was negative for anti-GQ1b antibodies, and brain imaging and cerebrospinal fluid (CSF) analysis were normal. Despite initial clinical deterioration and the need for intubation, she was treated successfully with intravenous immunoglobulin and eventually recovered. This case demonstrates that BBE and MFS can overlap and that early clinical diagnosis becomes essential even if anti-ganglioside antibodies, CSF and imaging studies are negative."

This study assessed the feasibility, safety, and diagnostic performance of a surgeon-controlled, free-hand extraocular muscle electrode placement for corticobulbar motor evoked potentials (cb-MEPs) and direct nerve stimulation (DNS). This monocentric, observational, retrospective study enrolled 40 patients scheduled for skull base tumor surgery, with planned intraoperative monitoring of CN III and/or VI. Curved needle electrodes were placed free-hand by the neurosurgeon at the scleral\u2013muscular junction of the medial and/or lateral rectus, and cb-MEPs and DNS were recorded; evaluability required reproducible baselines. Primary endpoint was 3-month cranial nerve palsy. Diagnostic accuracy was calculated, and Spearman correlations tested the relationship between intraoperative percentage amplitude change and postoperative deficit severity. Placement succeeded in all cases (mean 10 min) with one transient conjunctivitis (2.5%). Stable baseline cb-MEPs occurred in 20/37 (CN III) and 18/31 (CN VI). For CN III, cb-MEPs showed sensitivity 66.7% and specificity 100%; amplitude reduction correlated with postoperative severity (\u03c1\u2009=\u20090.94, p\u2009<\u20090.001).

This neurosurgeon-performed, free-hand technique enabled rapid, safe, and reproducible electrode placement for extraocular cranial nerve monitoring during skull base surgery. When baselines are obtainable, cb-MEPs and DNS provide highly specific, actionable feedback aligned with postoperative outcomes.

Clinicians must remain vigilant for neuroinvasive illness in patients presenting with febrile symptoms and malaise following mosquito exposure. While magnetic resonance imaging and cerebrospinal fluid analysis aid in differential diagnosis, detecting West Nile immunoglobulin M in serum is crucial for definitive diagnosis. Treatment primarily involves supportive care due to the absence of established regimens, though promising outcomes have been reported with plasma exchange and intravenous immunoglobulin. We present the case of an 83-year-old resident of Alabama, an avid gardener living near a pond, who initially exhibited symptoms of productive cough, diarrhea, fever, and generalized malaise. However, within 48 h, he developed hypoxemia, functional quadriplegia, and bulbar palsy necessitating intubation. Diagnostic evaluations, including magnetic resonance imaging and positive West Nile virus immunoglobulin M in serum, confirmed West Nile virus-associated poliomyelitis viral syndrome, prompting intravenous immunoglobulin therapy. This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions. The case also begs the question of the timing and efficacy of intravenous immunoglobulin and plasma exchange in West Nile virus infection and the fact that more data should be collected on these therapies."

While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS."

Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov. (Unique identifier: NCT06319534, 20/03/2024)."

Patients were randomly assigned using a random number table to either a control group (n = 55) receiving conventional pharmacotherapy combined with rehabilitation training, or a treatment group (n = 55) receiving the same conventional therapy plus additional EMG-guided targeted injections of mecobalamin into the swallowing muscles. Swallowing function was assessed using the Wada water swallowing test (WST) and videofluoroscopic swallowing study (VFSS) after 2 weeks of treatment.

Diagnostic accuracy was calculated, and Spearman correlations tested the relationship between intraoperative percentage amplitude change and postoperative deficit severity. Placement succeeded in all cases (mean 10 min) with one transient conjunctivitis (2.5%). Stable baseline cb-MEPs occurred in 20/37 (CN III) and 18/31 (CN VI). For CN III, cb-MEPs showed sensitivity 66.7% and specificity 100%; amplitude reduction correlated with postoperative severity (\u03c1\u2009=\u20090.94, p\u2009<\u20090.001). DNS was evaluable in 22/26, with sensitivity 83.3% and specificity 100%. For CN VI, cb-MEPs showed sensitivity 75.0% and specificity 96.8%, with correlation to severity (\u03c1\u2009=\u20090.88, p\u2009<\u20090.001). DNS elicited responses in 15/22, with sensitivity 75.0% and specificity 100%. This neurosurgeon-performed, free-hand technique enabled rapid, safe, and reproducible electrode placement for extraocular cranial nerve monitoring during skull base surgery. When baselines are obtainable, cb-MEPs and DNS provide highly specific, actionable feedback aligned with postoperative outcomes. These findings support pragmatic adoption and prospective multicenter validation."

Clinicians must remain vigilant for neuroinvasive illness in patients presenting with febrile symptoms and malaise following mosquito exposure. While magnetic resonance imaging and cerebrospinal fluid analysis aid in differential diagnosis, detecting West Nile immunoglobulin M in serum is crucial for definitive diagnosis. Treatment primarily involves supportive care due to the absence of established regimens, though promising outcomes have been reported with plasma exchange and intravenous immunoglobulin. We present the case of an 83-year-old resident of Alabama, an avid gardener living near a pond, who initially exhibited symptoms of productive cough, diarrhea, fever, and generalized malaise. However, within 48 h, he developed hypoxemia, functional quadriplegia, and bulbar palsy necessitating intubation. Diagnostic evaluations, including magnetic resonance imaging and positive West Nile virus immunoglobulin M in serum, confirmed West Nile virus-associated poliomyelitis viral syndrome, prompting intravenous immunoglobulin therapy. This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions. The case also begs the question of the timing and efficacy of intravenous immunoglobulin and plasma exchange in West Nile virus infection and the fact that more data should be collected on these therapies."

Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction. The nomogram model demonstrated an area under the ROC curve of 0.990, reflecting good potential clinical effect. The calibration curve showed good agreement between actual observations and nomogram predictions. The findings indicate that early assessment of the occurrence of bulbar palsy, mEGOS, IMN numbers, and NLR value can predict poor prognosis, with their combination providing improved accuracy for short-term prognosis in patients with severe GBS."

Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov. (Unique identifier: NCT06319534, 20/03/2024)."

Therefore, we aim to develop and validate a clinical prediction model to predict respiratory failure risk in pediatric GBS patients in China, alongside the economic immunological biomarkers in decision-making, and evaluate the Erasmus GBS Respiratory Insufficiency Score (EGRIS)-Kids score's efficacy. The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation."

Impairment of these neural networks causes progressive muscle atrophy and weakness that spreads throughout the body, resulting in life-threatening bulbar palsy and respiratory muscle paralysis. However, no therapeutic strategy has yet been established to halt ALS progression. Although evidence for clinical practice in ALS remains insufficient, novel research findings have steadily accumulated in recent years. To provide updated evidence-based or expert consensus recommendations for the diagnosis and management of ALS, the ALS Clinical Practice Guideline Development Committee, approved by the Japanese Society of Neurology, revised and published the Japanese clinical practice guidelines for the management of ALS in 2023. In this guideline, disease-modifying therapies that have accumulated evidence from randomized controlled trials were defined as \"Clinical Questions,\" in which the level of evidence was determined by systematic reviews. In contrast, \"Questions and Answers\" were defined as issues of clinically important but insufficient evidence, according to reports of a small number of cases, observational studies, and expert opinions. Based on a literature search performed in February 2022, recommendations were reached by consensus, determined by an independent panel, reviewed by external reviewers, and submitted for public comments by Japanese Society of Neurology members before publication. In this article, we summarize the revised Japanese guidelines for ALS, highlighting the regional and cultural diversity of care processes and decision-making. The guidelines cover a broad range of essential topics such as etiology, diagnostic criteria, disease monitoring and treatments, management of symptoms, respiration, rehabilitation, nutrition, metabolism, patient instructions, and various types of care support. We believe that this summary will help improve the daily clinical practice for individuals living with ALS and their caregivers."

To measure tongue atrophy, an operator independent automatic segmentation of the tongue is crucial. The aim of this study was to apply convolutional neural network (CNN) to MRI data in order to determine the volume of the tongue. A single triplanar CNN of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head. The 3D volumes were processed slice-wise across the three orientations and the predictions were merged using different voting strategies. This approach was developed using MRI datasets from 20 patients with 'classical' spinal amyotrophic lateral sclerosis (ALS) and 20 healthy controls and, in a pilot study, applied to the tongue volume quantification to 19 controls and 19 ALS patients with the variant progressive bulbar palsy (PBP). Consensus models with softmax averaging and majority voting achieved highest segmentation accuracy and outperformed predictions on single orientations and consensus models with union and unanimous voting. At the group level, reduction in tongue volume was not observed in classical spinal ALS, but was significant in the PBP group, as compared to controls. Utilizing single U-Net trained on three orthogonal orientations with consequent merging of respective orientations in an optimized consensus model reduces the number of erroneous detections and improves the segmentation of the tongue. The CNN-based automatic segmentation allows for accurate quantification of the tongue volumes in all subjects. The application to the ALS variant PBP showed significant reduction of the tongue volume in these patients and opens the way for unbiased future longitudinal studies in diseases affecting tongue volume."

Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke. This randomized controlled study included 148 patients with bulbar palsy after ischemic stroke who underwent routine treatment and swallowing rehabilitation training in the Department of Rehabilitation Medicine between July 2017 and July 2019 in China. The participants were randomly divided into the IOE group (n=74) and NG group (n=74) with IOE and NG as nutritional supports, respectively. The primary outcome was nutritional status including (1) body mass index (kg/m2), (2) serum ALB (albumin, g/L), and (3) PA (prealbumin, mg/L). The secondary outcomes were (1) swallowing function including (i) Functional Oral Intake Scale (FOIS) and (ii) Penetration-Aspiration Scale, (2) pneumonia, (3) depression, and (4) adverse events. Statistical analyses for continuous outcomes were performed using t test, Mann-Whitney U test and Wilcoxon signed-rank test and categorical variables using \u03c72 test. SPSS 21.0 was used for all analysis. There were no significant baseline differences between the 2 groups.

ALS pathology primarily involves the failure of protein quality control mechanisms, leading to the accumulation of misfolded proteins, particularly TAR DNA-binding protein 43 (TDP-43). TDP-43 aggregation is a central pathological feature of ALS. Maintaining protein homeostasis is critical and facilitated by heat shock proteins (HSPs), particularly the HSP40 family, which includes co-chaperones such as DNAJC7. Here, we report a family with three siblings affected by ALS who carry a homozygous c.518dupC frameshift variant in DNAJC7, a member of the HSP40 family. All three patients exhibited progressive muscle weakness, limb atrophy, bulbar palsy, and respiratory failure. Pathological examination revealed degeneration of both upper and lower motor neurons, with phosphorylated TDP-43-positive neuronal cytoplasmic inclusions in the frontal and temporal cortices. Immunoblot analysis were consistent with a type B pattern of phosphorylated TDP-43 in the precentral gyrus. Immunohistochemistry and RNA sequencing analyses demonstrated a substantial reduction in DNAJC7 expression at both the protein and RNA levels in affected brain regions. In a TDP-43 cell model, DNAJC7 knockdown impaired the disassembly of TDP-43 following arsenite-induced stress, whereas DNAJC7 overexpression suppressed the assembly and promoted the disassembly of arsenite-induced TDP-43 condensates. Furthermore, in a zebrafish ALS model, dnajc7 knockdown resulted in increased TDP-43 aggregation in motor neurons and reduced survival. To the best of our knowledge, this study provides the first evidence linking biallelic loss-of-function variants in DNAJC7 to familial ALS with TDP-43 pathology."

Case 1 involved a 62-year-old woman who presented with lower-extremity muscle weakness with lower motor neuron signs. The patient developed bulbar palsy and died of respiratory failure 9\u2009years after onset. Case 2 (the second son of Case 1) presented with lower-extremity muscle weakness at the age of 38\u2009years, with upper and lower motor neuron signs and died of respiratory failure 8\u2009years after onset. The pathological findings in both cases predominantly consisted of lower motor neuron loss and degeneration of the lateral and posterior funiculi. Numerous conglomerate hyaline inclusions (CHIs) were observed in the remaining motor neurons. Vacuole formation was observed inside the inclusions, sometimes with granular structures. Some inclusions were positive for ubiquitin, p62, and SOD1. Electron microscopy revealed that CHIs were composed of neurofilaments and expanded mitochondria. By literature review, ALS with p. L127S disclosed a male-dominant incidence rate, a variety of ages at onset, and low penetrance. The initial symptom was exclusively lower limb weakness. One-third of the patients only showed lower motor neuron signs and half did not present with bulbar symptoms. The neuropathological findings commonly observed in ALS with p. L127S variants were mainly the degeneration of lower motor neurons and the sensory system, including the posterior column, Clarke's nucleus, and the associated cerebellar system. The formation of intracytoplasmic hyaline inclusions was also a prominent feature. ALS with p. L127S variant should be included in the possible diagnosis of slowly progressive muscle weakness in the lower extremities, with or without family history or upper motor neuron signs. The loss of lower motor neurons and the accumulation of neurofilaments in the remaining neurons are key to the pathological diagnosis for ALS with p. L127S variant."

Methods: A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children's Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results: A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71\u00b18) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23\u00b13) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge (Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions: Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment. \u76ee\u7684\uff1a \u603b\u7ed3\u513f\u7ae5\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u7684\u4e34\u5e8a\u7279\u70b9\u3001\u6cbb\u7597\u53ca\u9884\u540e\u3002 \u65b9\u6cd5\uff1a \u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\uff0c\u9009\u62e92019\u5e743\u6708\u81f32024\u5e7412\u6708\u5728\u5e7f\u5dde\u533b\u79d1\u5927\u5b66\u9644\u5c5e\u5987\u5973\u513f\u7ae5\u533b\u7597\u4e2d\u5fc3\u795e\u7ecf\u5185\u79d1\u4e34\u5e8a\u8bca\u65ad\u4e3a\u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u768425\u4f8b\u60a3\u513f\uff0c\u6536\u96c6\u5e76\u5206\u6790\u5176\u4e34\u5e8a\u8d44\u6599\u53ca\u6cbb\u7597\u968f\u8bbf\u8d44\u6599\u3002\u91c7\u7528Mann-Whitney U\u68c0\u9a8c\u6bd4\u8f83\u60a3\u513fHughes\u529f\u80fd\u5206\u7ea7\u8bc4\u5206\uff08HFGS\uff09\u53d8\u5316\u3002 \u7ed3\u679c\uff1a 25\u4f8b\u60a3\u513f\u753712\u4f8b\u3001\u597313\u4f8b\uff0c\u9996\u6b21\u53d1\u75c5\u5e74\u9f84\u4e3a\uff0871\u00b18\uff09\u6708\u9f84\u300216\u4f8b\uff0864%\uff09\u6709\u524d\u9a71\u611f\u67d3\uff0c\u5176\u4e2d13\u4f8b\u4e3a\u547c\u5438\u9053\u611f\u67d3\u3002\u75be\u75c5\u9ad8\u5cf0\u65f6\u795e\u7ecf\u7cfb\u7edf\u75c7\u72b6\u5305\u62ec\u80a2\u4f53\u65e0\u529b21\u4f8b\uff0884%\uff09\u3001\u7403\u9ebb\u75f913\u4f8b\uff0852%\uff09\u3001\u55dc\u77617\u4f8b\uff0828%\uff09\u3001\u80a2\u4f53\u75bc\u75db9\u4f8b\uff0836%\uff09\u3001\u5171\u6d4e\u5931\u8c036\u4f8b\uff0824%\uff09\u3001\u547c\u5438\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u773c\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u5355\u4fa7\u9762\u795e\u7ecf\u9ebb\u75f94\u4f8b\uff0816%\uff09\u300223\u4f8b\u60a3\u513f\u8111\u810a\u6db2\u68c0\u67e5\uff0c\u86cb\u767d-\u7ec6\u80de\u5206\u79bb18\u4f8b\u300225\u4f8b\u60a3\u513f\u5168\u810a\u67f1\u78c1\u5171\u632f\u6210\u50cf\uff08MRI\uff09\u68c0\u67e5\u793a\u810a\u795e\u7ecf\u6839\u5f3a\u531618\u4f8b\uff0c\u67d4\u8111\u819c\u5f3a\u5316\u5408\u5e76\u810a\u795e\u7ecf\u6839\u5f3a\u53161\u4f8b\u300216\u4f8b\u60a3\u513f\u63a5\u53d7\u808c\u7535\u56fe\u68c0\u67e5\uff0c15\u4f8b\u5f02\u5e38\uff0c\u5176\u4e2d\u8131\u9ad3\u9798\u75c5\u53d88\u4f8b\u3001\u8131\u9ad3\u9798\u5408\u5e76\u8f74\u7d22\u75c5\u53d84\u4f8b\uff0c\u8f74\u7d22\u75c5\u53d83\u4f8b\u3002\u9759\u8109\u8f93\u6ce8\u514d\u75ab\u7403\u86cb\u767d\uff08IVIG\uff09\u6cbb\u7597 21\u4f8b\uff0884%\uff09\uff0c\u5176\u4e2d3\u4f8b\u60a3\u513fIVIG\u6cbb\u7597\u540e\u75c5\u60c5\u8fdb\u5c55\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\u884c\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u53ca\u8840\u6db2\u51c0\u5316\u6cbb\u7597\uff0c\u5305\u62ec\u8840\u6d46\u7f6e\u63622\u4f8b\u3001\u514d\u75ab\u5438\u9644\u6cbb\u75971\u4f8b\u30024\u4f8b\u60a3\u513f\u62d2\u7eddIVIG\u6cbb\u7597\u63a5\u53d7\u9759\u8109\u8f93\u6ce8\u7532\u6cfc\u5c3c\u9f99\uff08IVMP\uff09\u6cbb\u7597\uff0c\u5176\u4e2d1\u4f8b\u56e0\u547c\u5438\u808c\u9ebb\u75f9\u63a5\u53d7\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u6cbb\u7597\uff0c\u7ee7\u7eedIVMP\u5e8f\u8d2f\u6cbb\u7597\u540e\u62d4\u9664\u6c14\u7ba1\u63d2\u7ba1\u300225\u4f8b\u60a3\u513f\u9996\u6b21\u53d1\u75c5\u6025\u6027\u671f\u7684\u4f4f\u9662\u65f6\u95f4\u4e3a\uff0823\u00b13\uff09d\uff0c\u51fa\u9662\u65f6HFGS 1.6\uff080.6\uff0c2.7\uff09\u5206\uff0c\u9996\u6b21\u53d1\u75c5\u51fa\u9662\u81f3\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u7684\u65f6\u95f4\u95f4\u9694\u4e3a12\uff084\uff0c18\uff09\u4e2a\u6708\uff0cHFGS 0.1\uff080.0\uff0c0.5\uff09\u5206\uff0c\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u65f6HFGS\u4f4e\u4e8e\u51fa\u9662\u65f6\uff08Z=4.38\uff0cP<0.05\uff09\u30022\u4f8b\u60a3\u513f\u590d\u53d1\uff0c\u518d\u6b21\u4e88IVIG\u6cbb\u7597\u540e\u7f13\u89e3\uff0c\u968f\u8bbf1\u5e74\u672a\u518d\u590d\u53d1\u3002 \u7ed3\u8bba\uff1a \u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u6025\u6027\u671f\u5e38\u89c1\u7684\u75c7\u72b6\u4e3a\u80a2\u4f53\u65e0\u529b\u53ca\u7403\u9ebb\u75f9\uff0c\u4e25\u91cd\u8005\u53ef\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\uff0c\u808c\u7535\u56fe\u4ee5\u8131\u9ad3\u9798\u75c5\u53d8\u591a\u89c1\uff0cMRI\u810a\u795e\u7ecf\u6839\u5316\u5e38\u89c1\uff0c\u591a\u6570\u60a3\u513fIVIG\u514d\u75ab\u6cbb\u7597\u6548\u679c\u826f\u597d\uff0c\u65e0\u4e25\u91cd\u795e\u7ecf\u7cfb\u7edf\u540e\u9057\u75c7\u6b8b\u7559\u3002\u5c11\u6570\u60a3\u513f\u53ef\u80fd\u590d\u53d1\u3002."

Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction. The nomogram model demonstrated an area under the ROC curve of 0.990, reflecting good potential clinical effect. The calibration curve showed good agreement between actual observations and nomogram predictions. The findings indicate that early assessment of the occurrence of bulbar palsy, mEGOS, IMN numbers, and NLR value can predict poor prognosis, with their combination providing improved accuracy for short-term prognosis in patients with severe GBS."

Therefore, we aim to develop and validate a clinical prediction model to predict respiratory failure risk in pediatric GBS patients in China, alongside the economic immunological biomarkers in decision-making, and evaluate the Erasmus GBS Respiratory Insufficiency Score (EGRIS)-Kids score's efficacy. The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation."

Impairment of these neural networks causes progressive muscle atrophy and weakness that spreads throughout the body, resulting in life-threatening bulbar palsy and respiratory muscle paralysis. However, no therapeutic strategy has yet been established to halt ALS progression. Although evidence for clinical practice in ALS remains insufficient, novel research findings have steadily accumulated in recent years. To provide updated evidence-based or expert consensus recommendations for the diagnosis and management of ALS, the ALS Clinical Practice Guideline Development Committee, approved by the Japanese Society of Neurology, revised and published the Japanese clinical practice guidelines for the management of ALS in 2023. In this guideline, disease-modifying therapies that have accumulated evidence from randomized controlled trials were defined as \"Clinical Questions,\" in which the level of evidence was determined by systematic reviews. In contrast, \"Questions and Answers\" were defined as issues of clinically important but insufficient evidence, according to reports of a small number of cases, observational studies, and expert opinions. Based on a literature search performed in February 2022, recommendations were reached by consensus, determined by an independent panel, reviewed by external reviewers, and submitted for public comments by Japanese Society of Neurology members before publication. In this article, we summarize the revised Japanese guidelines for ALS, highlighting the regional and cultural diversity of care processes and decision-making. The guidelines cover a broad range of essential topics such as etiology, diagnostic criteria, disease monitoring and treatments, management of symptoms, respiration, rehabilitation, nutrition, metabolism, patient instructions, and various types of care support. We believe that this summary will help improve the daily clinical practice for individuals living with ALS and their caregivers."

To measure tongue atrophy, an operator independent automatic segmentation of the tongue is crucial. The aim of this study was to apply convolutional neural network (CNN) to MRI data in order to determine the volume of the tongue. A single triplanar CNN of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head. The 3D volumes were processed slice-wise across the three orientations and the predictions were merged using different voting strategies. This approach was developed using MRI datasets from 20 patients with 'classical' spinal amyotrophic lateral sclerosis (ALS) and 20 healthy controls and, in a pilot study, applied to the tongue volume quantification to 19 controls and 19 ALS patients with the variant progressive bulbar palsy (PBP). Consensus models with softmax averaging and majority voting achieved highest segmentation accuracy and outperformed predictions on single orientations and consensus models with union and unanimous voting. At the group level, reduction in tongue volume was not observed in classical spinal ALS, but was significant in the PBP group, as compared to controls. Utilizing single U-Net trained on three orthogonal orientations with consequent merging of respective orientations in an optimized consensus model reduces the number of erroneous detections and improves the segmentation of the tongue. The CNN-based automatic segmentation allows for accurate quantification of the tongue volumes in all subjects. The application to the ALS variant PBP showed significant reduction of the tongue volume in these patients and opens the way for unbiased future longitudinal studies in diseases affecting tongue volume."

Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke. This randomized controlled study included 148 patients with bulbar palsy after ischemic stroke who underwent routine treatment and swallowing rehabilitation training in the Department of Rehabilitation Medicine between July 2017 and July 2019 in China. The participants were randomly divided into the IOE group (n=74) and NG group (n=74) with IOE and NG as nutritional supports, respectively. The primary outcome was nutritional status including (1) body mass index (kg/m2), (2) serum ALB (albumin, g/L), and (3) PA (prealbumin, mg/L). The secondary outcomes were (1) swallowing function including (i) Functional Oral Intake Scale (FOIS) and (ii) Penetration-Aspiration Scale, (2) pneumonia, (3) depression, and (4) adverse events. Statistical analyses for continuous outcomes were performed using t test, Mann-Whitney U test and Wilcoxon signed-rank test and categorical variables using \u03c72 test. SPSS 21.0 was used for all analysis. There were no significant baseline differences between the 2 groups. After the treatment, the IOE group demonstrated significantly better results compared with the NG group in ALB ([32.71\u00b10.94] versus [32.28\u00b10.81] g/L; P=0.003), PA ([278.15\u00b113.81] versus [270.31\u00b115.08] mg/L; P=0.001], body mass index ([19.77\u00b11.03] versus [19.41\u00b10.98] kg/m2; P=0.002], FOIS (P<0.001), Penetration-Aspiration Scale (P<0.001), stroke-associated pneumonia ([1, 4.05%] versus [26, 35.14%]; P<0.001), depression ([1, 1.35%] versus [44, 59.46%]; P<0.001) and overall less adverse events (reflux, fever, discomfort in the throat; P<0.001). In patients with dysphagia with bulbar palsy after ischemic stroke who received routine treatment and swallowing rehabilitation training, IOE is safer and more conducive to the improvement of nutritional status, swallowing function, stroke-associated pneumonia, and depression than NG.

Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function. In this report, we describe mice that express globally reduced levels of calcium-modulating cyclophilin ligand (CAML) protein. CAML is an essential component in the transmembrane domain recognition complex (TRC) pathway, responsible for inserting C-terminal tail anchored (TA) proteins into the endoplasmic reticulum membrane. The primary phenotype observed in these mice was rapid development of hind limb weakness and paralysis. Spinal cord sections revealed a loss of motor neuron cell bodies. Targeting CAML loss specifically to neurons using SLICK-H-Cre or synapsin-Cre transgenic mice yielded similar phenotypes, indicating that CAML plays a cell autonomous role in this process. We found that intracellular trafficking was perturbed in cells depleted of CAML, with aberrant release of procathepsin D and defective retention of CD222 within the trans-Golgi network, as well as reduced levels and mislocalization of syntaxin 5 (Stx5). Dysfunctional lysosomes and abnormal protein glycosylation were also revealed in CAML deficient cells, further indicating a defect in Golgi trafficking. In addition, we observed an identical phenotype in mice lacking ASNA1 in neurons, suggesting that CAML's role in sustaining muscle function is related to its involvement in the TRC pathway. Together, these findings implicate motor neuron survival as a key role for the TA protein insertion machinery in mice, which may shed light on the pathogenesis of neuromuscular disease in humans."

HIV infection can cause an MND-like syndrome due to central nervous system (CNS) involvement de novo or during antiretroviral therapy (ART) due to CNS escape. We present two cases: one with a classic amyotrophic lateral sclerosis (ALS) phenotype, which was the manifestation of symptomatic CNS escape from ART, and the second with a primary lateral sclerosis (PLS) phenotype associated with underlying HIV infection. A systematic review of published literature of people living with HIV (PLHIV) who developed ALS/ MND was conducted using the PubMed, Embase, and Lilacs databases. A total of 91 cases were found, 89 of which were obtained from 37 articles, and two were included from our own case series. In patients with HIV-associated MND, 63 patients reviewed had a classic ALS phenotype followed by progressive muscular atrophy variant (12), progressive bulbar palsy (8), PLS (7) and bulbar onset ALS (1). Neuroimaging, electrophysiology, cerebrospinal fluid (CSF) analysis, CSF and serum HIV viral load, and CD4 count investigations were used for diagnosis. Following the initiation or modification of antiretroviral therapy (ART), approximately 70% exhibited an improvement or a stable disease course. HIV-associated MND is a rare condition that can occur in both ART-naive individuals and those on treatment. A proportion of cases (~\u200970%) show improvement with ART. Accurate diagnosis requires the exclusion of opportunistic infections, which remains a critical yet challenging aspect of managing this condition."

Therefore, we aim to develop and validate a clinical prediction model to predict respiratory failure risk in pediatric GBS patients in China, alongside the economic immunological biomarkers in decision-making, and evaluate the Erasmus GBS Respiratory Insufficiency Score (EGRIS)-Kids score's efficacy. The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation."

Impairment of these neural networks causes progressive muscle atrophy and weakness that spreads throughout the body, resulting in life-threatening bulbar palsy and respiratory muscle paralysis. However, no therapeutic strategy has yet been established to halt ALS progression. Although evidence for clinical practice in ALS remains insufficient, novel research findings have steadily accumulated in recent years. To provide updated evidence-based or expert consensus recommendations for the diagnosis and management of ALS, the ALS Clinical Practice Guideline Development Committee, approved by the Japanese Society of Neurology, revised and published the Japanese clinical practice guidelines for the management of ALS in 2023. In this guideline, disease-modifying therapies that have accumulated evidence from randomized controlled trials were defined as \"Clinical Questions,\" in which the level of evidence was determined by systematic reviews. In contrast, \"Questions and Answers\" were defined as issues of clinically important but insufficient evidence, according to reports of a small number of cases, observational studies, and expert opinions. Based on a literature search performed in February 2022, recommendations were reached by consensus, determined by an independent panel, reviewed by external reviewers, and submitted for public comments by Japanese Society of Neurology members before publication. In this article, we summarize the revised Japanese guidelines for ALS, highlighting the regional and cultural diversity of care processes and decision-making. The guidelines cover a broad range of essential topics such as etiology, diagnostic criteria, disease monitoring and treatments, management of symptoms, respiration, rehabilitation, nutrition, metabolism, patient instructions, and various types of care support. We believe that this summary will help improve the daily clinical practice for individuals living with ALS and their caregivers."

To measure tongue atrophy, an operator independent automatic segmentation of the tongue is crucial. The aim of this study was to apply convolutional neural network (CNN) to MRI data in order to determine the volume of the tongue. A single triplanar CNN of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head. The 3D volumes were processed slice-wise across the three orientations and the predictions were merged using different voting strategies. This approach was developed using MRI datasets from 20 patients with 'classical' spinal amyotrophic lateral sclerosis (ALS) and 20 healthy controls and, in a pilot study, applied to the tongue volume quantification to 19 controls and 19 ALS patients with the variant progressive bulbar palsy (PBP). Consensus models with softmax averaging and majority voting achieved highest segmentation accuracy and outperformed predictions on single orientations and consensus models with union and unanimous voting. At the group level, reduction in tongue volume was not observed in classical spinal ALS, but was significant in the PBP group, as compared to controls. Utilizing single U-Net trained on three orthogonal orientations with consequent merging of respective orientations in an optimized consensus model reduces the number of erroneous detections and improves the segmentation of the tongue. The CNN-based automatic segmentation allows for accurate quantification of the tongue volumes in all subjects. The application to the ALS variant PBP showed significant reduction of the tongue volume in these patients and opens the way for unbiased future longitudinal studies in diseases affecting tongue volume."

Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke. This randomized controlled study included 148 patients with bulbar palsy after ischemic stroke who underwent routine treatment and swallowing rehabilitation training in the Department of Rehabilitation Medicine between July 2017 and July 2019 in China. The participants were randomly divided into the IOE group (n=74) and NG group (n=74) with IOE and NG as nutritional supports, respectively. The primary outcome was nutritional status including (1) body mass index (kg/m2), (2) serum ALB (albumin, g/L), and (3) PA (prealbumin, mg/L). The secondary outcomes were (1) swallowing function including (i) Functional Oral Intake Scale (FOIS) and (ii) Penetration-Aspiration Scale, (2) pneumonia, (3) depression, and (4) adverse events. Statistical analyses for continuous outcomes were performed using t test, Mann-Whitney U test and Wilcoxon signed-rank test and categorical variables using \u03c72 test. SPSS 21.0 was used for all analysis. There were no significant baseline differences between the 2 groups. After the treatment, the IOE group demonstrated significantly better results compared with the NG group in ALB ([32.71\u00b10.94] versus [32.28\u00b10.81] g/L; P=0.003), PA ([278.15\u00b113.81] versus [270.31\u00b115.08] mg/L; P=0.001], body mass index ([19.77\u00b11.03] versus [19.41\u00b10.98] kg/m2; P=0.002], FOIS (P<0.001), Penetration-Aspiration Scale (P<0.001), stroke-associated pneumonia ([1, 4.05%] versus [26, 35.14%]; P<0.001), depression ([1, 1.35%] versus [44, 59.46%]; P<0.001) and overall less adverse events (reflux, fever, discomfort in the throat; P<0.001). In patients with dysphagia with bulbar palsy after ischemic stroke who received routine treatment and swallowing rehabilitation training, IOE is safer and more conducive to the improvement of nutritional status, swallowing function, stroke-associated pneumonia, and depression than NG.

However, most research has focused on its later stages rather than its earlier stages, including the prognosis of patients with this condition, or factors that act as early predictors of risk. Therefore, our study aimed to identify early predictors of respiratory muscle paralysis in patients with GBS and determine the short-term prognosis of such patients. We recruited 455 GBS patients (age \u2265 18) who had been hospitalized in the First Affiliated Hospital of Harbin Medical University between 2016 and 2021, retrospectively. We recorded clinical and laboratory data and used linear and logistic regression analysis to investigate the relationship between early clinical, examination results, and subsequent respiratory muscle paralysis. Among the 455 patients, 129 were assigned to a respiratory muscle paralysis group and 326 were assigned to a non-respiratory muscle paralysis group. Compared with the non-affected group, the time from onset to admission was shorter (p = 0.0003), and the Medical Research Council (MRC) score at admission and discharge was smaller in the affected group (p < 0.0001). Compared with the non-affected group, the affected group had higher Hughes and Erasmus GBS Respiratory Insufficiency Score (EGRIS) scores at admission and longer hospital stays (p < 0.0001). Patients in the affected group were more likely to have bulbar palsy and lung infections (p < 0.0001). To conclude, bulbar palsy, a higher EGRIS score and Hughes score at admission, a lower MRC score, and a shorter time between onset and admission, are all predictive risk factors for respiratory muscle paralysis in patients with GBS. An increase in any of these factors increases the risk of muscle paralysis. Patients with respiratory muscle paralysis have a poorer short-term prognosis than those without respiratory muscle paralysis. Therefore, we should attempt to identify patients with one or more of these characteristics in the early stages of admission, provide ventilation management, and administer IMV treatment if necessary."

Data from the first 1500 patients included in the prospective International GBS Outcome Study (IGOS) were used. Patients were included across five continents. Patients <6 years and patients from Bangladesh were excluded. Univariable logistic and multivariable Cox regression were used to determine which prespecified clinical and diagnostic characteristics were associated with MV and to predict the risk of MV at multiple time points during disease course. 1133 (76%) patients met the study criteria. Independent predictors of MV were a shorter time from onset of weakness until admission, the presence of bulbar palsy and weakness of neck flexion and hip flexion. The modified EGRIS (mEGRIS) was based on these factors and accurately predicts the risk of MV with an area under the curve (AUC) of 0.84 (0.80-0.88). We internally validated the model within the full IGOS cohort and within separate regional subgroups, which showed AUC values of 0.83 (0.81-0.88) and 0.85 (0.72-0.98), respectively. The mEGRIS is a simple and accurate tool for predicting the risk of MV in GBS. Compared with the original model, the mEGRIS requires less information for predictions with equal accuracy, can be used to predict MV at multiple time points and is also applicable in less severely affected patients and GBS variants. Model performance was consistent across different regions."

Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy. Further prospective studies are needed to define optimal criteria and timing for early integration of these agents into the therapeutic algorithm."

A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS."

It is characterized by gradual disease progression with comparison to adult-onset ALS and is often linked to genetic mutations. A 16-years-old female presented with long history of generalized weakness since age of 10 years, followed by bilateral sensorineural hearing loss, bulbar symptoms, and limb spasticity. Neurological examination revealed upper motor neuron signs in upper limbs, lower motor neuron signs in lower limbs, and bulbar involvement. Nerve conduction test was normal however, MRI showed early degenerative changes, and diagnosed with J-ALS after careful evaluation. She was started on Riluzole. Despite ICU care and supportive interventions including PEG and tracheostomy, she succumbed to respiratory failure. Rarity, atypical presentation, and finical constraints can delay diagnosis of J-ALS. However, early diagnosis after careful evaluation of clinical symptoms, medical history, electrophysiological and imaging studies followed by prompt treatment with Riluzole and supportive interventions can help prolong survival and improve quality of life. J-ALS is a rare motor neuron disease which possess immense diagnostic challenges, can exhibit relentless progression over short period of time with time."

Clinical course and imaging findings raised strongly suggested bulbar palsy from a C4-5 intramedullary hemorrhagic lesion. Computed tomography and magnetic resonance imaging of the brain and cervical spine revealed an intramedullary mass at C4-5, accompanied by syringobulbia and syringomyelia, with signals extending from the lower medulla oblongata to the T1 spinal level. The patient underwent laminectomy, myelotomy, and microsurgical mass excision with intraoperative neurophysiological monitoring. Postoperative pathology confirmed the lesion as an ependymoma.

Following uncomplicated surgical debridement and discharge, the patient returned within hours exhibiting rapidly progressive ascending paralysis, bulbar weakness, and respiratory failure requiring intubation. Laboratory evaluation revealed profound hypokalemia (1.4 mmol/L), hypophosphatemia, and rhabdomyolysis. The clinical presentation, coupled with the patient's report of the firework emitting a green flare, is most consistent with acute barium toxicity. Formal toxicologic confirmation was not available; however, the clinical constellation, mechanism of injury, and rapid response to electrolyte repletion strongly support this diagnosis. Barium salts, commonly used in pyrotechnics to produce green coloration, can induce systemic toxicity by competitively blocking potassium channels, causing a widespread intracellular shift of potassium. This case highlights the rare but life-threatening systemic toxicity associated with soluble barium salts and the importance of considering toxicologic etiologies in trauma patients presenting with unexplained neurological collapse."

People with thymidine kinase 2 deficiency experience progressive myopathy, bulbar weakness and respiratory insufficiency, often losing the ability to walk, eat and breathe independently. Doxecitine and doxribtimine represents the first approved treatment for patients with thymidine kinase 2 deficiency with age of symptom onset \u226412 years by the US Food and Drug Administration and the European Medicines Agency; previously, disease management was limited to supportive care. We investigated the efficacy and safety of pyrimidine nucleos(t)ide therapy in thymidine kinase 2 deficiency. Patients treated with pyrimidine nucleos(t)ides were pooled from retrospective (NCT03701568, NCT05017818) and prospective (NCT03845712) studies and company-supported Expanded Access Programs. Untreated patients were pooled from literature reviews and a retrospective chart review study (NCT05017818). Patient subgroups were stratified by age of thymidine kinase 2 deficiency symptom onset (\u226412 years and >12 years). The primary outcome was survival in 50th-percentile matched pairs of treated and untreated patients. Other outcomes included status of developmental motor milestones, ventilatory and feeding tube support, and safety. In total, 218 patients were included (treated: 104; untreated: 114). Baseline demographics and characteristics were comparable between subgroups. Most patients had an age of symptom onset \u226412 years [treated: 82/104 (78.8%); untreated: 93/114 (81.6%)]. In the age-of-symptom-onset-\u226412-years subgroup, restricted mean survival time (95% confidence interval) was 29.2 (28.2, 30.3) years over the 30 years after symptom onset for treated patients and 14.4 (11.1, 17.6) years for untreated patients. Loss of \u22651 acquired motor milestone was more frequent before treatment start than after. Substantially more patients regained \u22651 lost motor milestone after treatment start than before. Ventilatory and feeding support were used across all age-of-symptom-onset subgroups, but some patients reduced or discontinued support after starting treatment and fewer patients initiated support after treatment start than before. Most treatment-emergent adverse events (TEAEs) did not lead to discontinuation. The most frequent TEAE was diarrhoea [43/50 patients (86.0%)], which was generally mild or moderate and resolved with dose reduction. Serious TEAEs occurred in 28/50 patients (56.0%); few were considered to be drug related [4/50 (8.0%)]. In total, 3/67 patients (4.5%) experienced a fatal serious TEAE, which were not considered to be drug related. These findings indicate that pyrimidine nucleos(t)ide therapy improves survival and functional outcomes in people with thymidine kinase 2 deficiency, especially those with age of symptom onset \u226412 years, and has an acceptable safety profile."

When accompanied by additional symptoms such as bulbar palsy, limb weakness, or lethargy, it is termed MFS overlap syndrome.

The patient had a preceding suspected case of chlamydial pneumonia before symptom onset, and his condition improved significantly following treatment with intravenous immunoglobulin. This case suggests that chlamydial pneumonia might predispose individuals to GBS.

PrimeC is a fixed-dose oral combination of celecoxib and ciprofloxacin designed to target ALS-related mechanisms, including neuroinflammation, iron homeostasis, and dysregulated microRNAs. To evaluate the safety, tolerability, and potential efficacy of PrimeC in people living with ALS. This was a randomized, double-blind, placebo-controlled, phase 2b trial conducted at 4 ALS referral centers from May 2022 to November 2023 and followed by 12-month open-label extension. Adults with definite or probable ALS and disease duration of 30 months or less were eligible. Of 73 screened, 69 were randomized and 68 were included in the intent-to-treat population. Participants were randomized 2:1 to receive PrimeC or placebo for 6 months, followed by open-label extension PrimeC for all. The primary outcome was safety and tolerability. The prespecified primary biomarker outcome was plasma neuron-derived-exosomal TAR DNA-binding protein 43 (TDP-43) or prostaglandinJ2. Secondary outcomes included change in ALS Functional Rating Scale-Revised (ALSFRS-R) score at 6 and 18 months, survival, and time-to-composite events. Exploratory biomarkers included neurofilament light chains, iron-regulatory proteins, and circulating microRNAs. The 68 participants were well balanced in age at entry and sex. In the PrimeC group, the mean (SD) age was 59.1 (9.1) years, and 27 of 45 participants were male. In the placebo group, the mean (SD) age was 55.0 (13.0) years, and 14 of 23 participants were male. PrimeC was well tolerated, with a safety profile comparable to placebo (adverse event rate, 66.7% PrimeC vs 65.2% placebo). Drug-related adverse events were more frequent with PrimeC (20.0% vs 4.3%), mostly mild to moderate, and transient. At month 6, the mean ALSFRS-R difference was 2.23 points between PrimeC and placebo (95% CI, -0.61 to 5.07; P\u2009=\u2009.12). At month 18, ALSFRS-R scores in participants continuously treated with PrimeC maintained a difference (7.92 points; 95% CI, 2.25 to 13.60; P\u2009=\u2009.007), with significant bulbar difference (3.18 points; 95% CI, 1.32 to 5.04; P\u2009=\u2009.001). Continuous treatment was associated with lower risk of ALS complications, including hospitalization, respiratory failure, or death (HR, 0.36; 95% CI, 0.15-0.85; P\u2009=\u2009.02). In the double-blind period, transferrin levels were preserved with PrimeC (1.90 \u03bcmol/L difference; P\u2009=\u2009.03), the negative ferritin-ALSFRS-R correlation observed in placebo (\u03c1\u2009=\u2009-0.50; P\u2009=\u2009.02) was abolished, and ALS-associated microRNAs were downregulated (log2 fold change: miR-199a-3p, -1.87; false discovery rate [FDR] P\u2009=\u2009.004; miR-199a-5p, -2.23; FDR P\u2009<\u2009.001; miR-181a-5p: -1.89; FDR P\u2009=\u2009.001; miR-181b-5p, -1.62; FDR P\u2009=\u2009.005). Prespecified neuron-derived exosome TDP-43/PgJ2 analyses will be reported separately following completion of development and analyses. PrimeC was safe and well tolerated over 18 months.

ALS patients with bulbar weakness often suffer from troublesome sialorrhea. Botulinum toxin injection, as a neuromuscular blocker, has been widely used in the treatment of sialorrhea. This paper evaluates the safety and efficacy of botulinum toxin injections for the treatment of sialorrhea in ALS patients through a systematic review and meta-analysis. METHODS: A systematic review and meta-analysis was conducted by searching eight databases, including PubMed, EMBASE, and CNKI, up to April 13, 2025. Eligible randomized controlled trials and quasi-experimental studies were analyzed using Review Manager 5.4 and Stata software. RESULTS: Thirteen studies (2 RCTs, 11 quasi-experimental studies) with 130 ALS patients were included. Botulinum toxin significantly reduced sialorrhea and improved quality of life (Z\u2009=\u200910.98, p\u2009<\u20090.00001; RD\u2009=\u20090.82, 95% CI: 0.67\u20130.97). The treatment effect was independent of toxin type (p\u2009=\u20090.48), injection site (p\u2009=\u20090.17), and ultrasound guidance use (p\u2009=\u20090.44). CONCLUSION: Botulinum toxin appears to be a safe and effective option for managing sialorrhea in ALS patients, regardless of injection technique. However, given that most included studies were observational, further validation through high-quality RCTs is warranted.

Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy. Further prospective studies are needed to define optimal criteria and timing for early integration of these agents into the therapeutic algorithm."

A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS."

Radiological diagnostics primarily serve to systematically exclude treatable mimics and support the clinical and electrophysiological diagnosis. The focus is on amyotrophic lateral sclerosis (ALS); supplementary progressive muscular atrophy (PMA, purely lower motor neuron, LMN disease) and spinal muscular atrophy (SMA). Which imaging signs support the diagnosis of ALS, how do electromyography/magnetic resonance imaging (EMG/MRI) fit into the Gold Coast criteria and which other motor neuron diseases are relevant? Overview of clinical criteria (Gold Coast), genetics and typical MRI findings of the brain, spinal cord and musculature. Gold Coast core: progressive motor deterioration, upper motor neuron (UMN) and LMN signs in \u2265\u202f1 region or LMN in \u2265\u202f2\u00a0regions and exclusion of alternative causes. susceptibility-weighted imaging (SWI) motor band sign as UMN marker; T2/fluid-attenuated inversion recovery (FLAIR) hyperintensities along the corticospinal tract with low sensitivity, moderate specificity; T1 bright tongue as an indication of chronic denervation in bulbar involvement. EMG: detection of subclinical LMN involvement, sometimes limited in UMN-dominant/bulbar courses. PMA: Pure purely LMN symptoms, often continuum to ALS. SMA: Autosomal autosomal recessive (SMN1 deletion). The diagnosis remains primarily clinical; EMG and MRI are supportive. The radiological priority is the exclusion of mimics. The UMN markers increase diagnostic certainty in the context of clinical/EMG findings but do not replace them. Clear findings facilitate classification according to Gold Coast. The PMA and SMA require careful differential diagnostics; characteristic MRI patterns support progression and treatment planning.

A 23-year-old man presented with persistent hiccups, pneumonia, and progressively worsening respiratory dysfunction. Clinical course and imaging findings raised strongly suggested bulbar palsy from a C4-5 intramedullary hemorrhagic lesion. Computed tomography and magnetic resonance imaging of the brain and cervical spine revealed an intramedullary mass at C4-5, accompanied by syringobulbia and syringomyelia, with signals extending from the lower medulla oblongata to the T1 spinal level. The patient underwent laminectomy, myelotomy, and microsurgical mass excision with intraoperative neurophysiological monitoring. Postoperative pathology confirmed the lesion as an ependymoma. Neurologic function improved steadily after surgery. Thus, central respiratory dysfunction should be considered in patients with severe pneumonia without underlying disease. Additionally, contrast-enhanced magnetic resonance imaging is essential for differential diagnosis in bulbar palsy cases."

Following uncomplicated surgical debridement and discharge, the patient returned within hours exhibiting rapidly progressive ascending paralysis, bulbar weakness, and respiratory failure requiring intubation. Laboratory evaluation revealed profound hypokalemia (1.4 mmol/L), hypophosphatemia, and rhabdomyolysis. The clinical presentation, coupled with the patient's report of the firework emitting a green flare, is most consistent with acute barium toxicity. Formal toxicologic confirmation was not available; however, the clinical constellation, mechanism of injury, and rapid response to electrolyte repletion strongly support this diagnosis. Barium salts, commonly used in pyrotechnics to produce green coloration, can induce systemic toxicity by competitively blocking potassium channels, causing a widespread intracellular shift of potassium. This case highlights the rare but life-threatening systemic toxicity associated with soluble barium salts and the importance of considering toxicologic etiologies in trauma patients presenting with unexplained neurological collapse."

People with thymidine kinase 2 deficiency experience progressive myopathy, bulbar weakness and respiratory insufficiency, often losing the ability to walk, eat and breathe independently. Doxecitine and doxribtimine represents the first approved treatment for patients with thymidine kinase 2 deficiency with age of symptom onset \u226412 years by the US Food and Drug Administration and the European Medicines Agency; previously, disease management was limited to supportive care. We investigated the efficacy and safety of pyrimidine nucleos(t)ide therapy in thymidine kinase 2 deficiency. Patients treated with pyrimidine nucleos(t)ides were pooled from retrospective (NCT03701568, NCT05017818) and prospective (NCT03845712) studies and company-supported Expanded Access Programs. Untreated patients were pooled from literature reviews and a retrospective chart review study (NCT05017818). Patient subgroups were stratified by age of thymidine kinase 2 deficiency symptom onset (\u226412 years and >12 years). The primary outcome was survival in 50th-percentile matched pairs of treated and untreated patients. Other outcomes included status of developmental motor milestones, ventilatory and feeding tube support, and safety. In total, 218 patients were included (treated: 104; untreated: 114). Baseline demographics and characteristics were comparable between subgroups. Most patients had an age of symptom onset \u226412 years [treated: 82/104 (78.8%); untreated: 93/114 (81.6%)]. In the age-of-symptom-onset-\u226412-years subgroup, restricted mean survival time (95% confidence interval) was 29.2 (28.2, 30.3) years over the 30 years after symptom onset for treated patients and 14.4 (11.1, 17.6) years for untreated patients. Loss of \u22651 acquired motor milestone was more frequent before treatment start than after. Substantially more patients regained \u22651 lost motor milestone after treatment start than before. Ventilatory and feeding support were used across all age-of-symptom-onset subgroups, but some patients reduced or discontinued support after starting treatment and fewer patients initiated support after treatment start than before. Most treatment-emergent adverse events (TEAEs) did not lead to discontinuation. The most frequent TEAE was diarrhoea [43/50 patients (86.0%)], which was generally mild or moderate and resolved with dose reduction. Serious TEAEs occurred in 28/50 patients (56.0%); few were considered to be drug related [4/50 (8.0%)]. In total, 3/67 patients (4.5%) experienced a fatal serious TEAE, which were not considered to be drug related. These findings indicate that pyrimidine nucleos(t)ide therapy improves survival and functional outcomes in people with thymidine kinase 2 deficiency, especially those with age of symptom onset \u226412 years, and has an acceptable safety profile."

When accompanied by additional symptoms such as bulbar palsy, limb weakness, or lethargy, it is termed MFS overlap syndrome. This report describes a male patient diagnosed with MFS overlap syndrome, presenting with ophthalmoplegia, ataxia, bulbar palsy, numbness in both arms, positive GM4 IgG antibodies, a persistent, intractable headache, and a delayed onset of left-sided peripheral facial palsy. The patient had a preceding suspected case of chlamydial pneumonia before symptom onset, and his condition improved significantly following treatment with intravenous immunoglobulin. This case suggests that chlamydial pneumonia might predispose individuals to GBS. Patients with MFS/pharyngeal-cervical-brachial (PCB) overlap syndrome may exhibit atypical symptoms, including persistent, intractable headaches, and delayed peripheral facial paralysis. Atypical symptoms should not delay the diagnosis and treatment of GBS once other conditions have been adequately excluded. The presence of anti-GM4 antibodies, often found alongside other anti-ganglioside antibodies, may serve as a critical immunological factor in MFS/PCB overlap syndrome."

PrimeC is a fixed-dose oral combination of celecoxib and ciprofloxacin designed to target ALS-related mechanisms, including neuroinflammation, iron homeostasis, and dysregulated microRNAs. To evaluate the safety, tolerability, and potential efficacy of PrimeC in people living with ALS. This was a randomized, double-blind, placebo-controlled, phase 2b trial conducted at 4 ALS referral centers from May 2022 to November 2023 and followed by 12-month open-label extension. Adults with definite or probable ALS and disease duration of 30 months or less were eligible. Of 73 screened, 69 were randomized and 68 were included in the intent-to-treat population. Participants were randomized 2:1 to receive PrimeC or placebo for 6 months, followed by open-label extension PrimeC for all. The primary outcome was safety and tolerability. The prespecified primary biomarker outcome was plasma neuron-derived-exosomal TAR DNA-binding protein 43 (TDP-43) or prostaglandinJ2. Secondary outcomes included change in ALS Functional Rating Scale-Revised (ALSFRS-R) score at 6 and 18 months, survival, and time-to-composite events. Exploratory biomarkers included neurofilament light chains, iron-regulatory proteins, and circulating microRNAs. The 68 participants were well balanced in age at entry and sex. In the PrimeC group, the mean (SD) age was 59.1 (9.1) years, and 27 of 45 participants were male. In the placebo group, the mean (SD) age was 55.0 (13.0) years, and 14 of 23 participants were male. PrimeC was well tolerated, with a safety profile comparable to placebo (adverse event rate, 66.7% PrimeC vs 65.2% placebo). Drug-related adverse events were more frequent with PrimeC (20.0% vs 4.3%), mostly mild to moderate, and transient. At month 6, the mean ALSFRS-R difference was 2.23 points between PrimeC and placebo (95% CI, -0.61 to 5.07; P\u2009=\u2009.12). At month 18, ALSFRS-R scores in participants continuously treated with PrimeC maintained a difference (7.92 points; 95% CI, 2.25 to 13.60; P\u2009=\u2009.007), with significant bulbar difference (3.18 points; 95% CI, 1.32 to 5.04; P\u2009=\u2009.001). Continuous treatment was associated with lower risk of ALS complications, including hospitalization, respiratory failure, or death (HR, 0.36; 95% CI, 0.15-0.85; P\u2009=\u2009.02). In the double-blind period, transferrin levels were preserved with PrimeC (1.90 \u03bcmol/L difference; P\u2009=\u2009.03), the negative ferritin-ALSFRS-R correlation observed in placebo (\u03c1\u2009=\u2009-0.50; P\u2009=\u2009.02) was abolished, and ALS-associated microRNAs were downregulated (log2 fold change: miR-199a-3p, -1.87; false discovery rate [FDR] P\u2009=\u2009.004; miR-199a-5p, -2.23; FDR P\u2009<\u2009.001; miR-181a-5p: -1.89; FDR P\u2009=\u2009.001; miR-181b-5p, -1.62; FDR P\u2009=\u2009.005). Prespecified neuron-derived exosome TDP-43/PgJ2 analyses will be reported separately following completion of development and analyses. PrimeC was safe and well tolerated over 18 months.

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

The claim of \"breakthroughs\" is supported by evidence demonstrating novel therapeutic interventions, improved diagnostic methodologies, and prognostic stratification tools, specifically within the contexts of stroke rehabilitation, degenerative motor neuron disorders, and immune-mediated neuropathies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of bulbar palsy has evolved significantly, shifting from strictly supportive care toward targeted, mechanism-based therapeutic strategies. Recent literature emphasizes the utility of ultrasound-guided interventions, such as stellate ganglion blocks, and electromyography-guided pharmacological injections to enhance swallowing efficacy. In the realm of degenerative conditions, the significance of early genetic testing and sustained riboflavin supplementation in disorders like Brown-Vialetto-Van Laere syndrome highlights a transition toward precision medicine. Furthermore, diagnostic innovations\u2014such as tongue shear wave elastography\u2014provide non-invasive, quantitative data for bulbar dysfunction in motor neuron diseases. These developments collectively signify a multidimensional approach to improving patient quality of life through enhanced pharyngeal mechanics and early diagnostic awareness.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Electromyography-guided targeted injections of mecobalamin represent a significant shift toward individualized pharmacotherapy for post-stroke bulbar palsy.\n*   Ultrasound-guided stellate ganglion block provides a safe, reproducible, and long-term functional improvement in swallowing function post-stroke, despite temporary effects on vertebral artery blood flow.\n*   Tongue shear wave elastography has emerged as a quantitative biomarker to non-invasively assess genioglossus muscle elasticity in bulbar-onset ALS.\n*   Spontaneous \"vacuum swallowing\" is a compensatory mechanism in patients with tracheostomy that, if recognized, can be harnessed for swallowing rehabilitation.\n*   Stellate ganglion blocks address both motor function (swallowing) and psychological status (anxiety) in bulbar-palsy patients.\n*   Bulbar palsy is confirmed as a significant, independent risk factor for the development of pneumonia in GBS patients.\n*   Early identification of bulbar palsy acts as a critical prognostic indicator for short-term outcomes in severe GBS cases.\n*   The use of botulinum toxin type A in pediatric traumatic third nerve palsy demonstrates how early intervention can prevent long-term sequelae through neural plasticity and muscle preservation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Current literature emphasizes quantitative assessments of lingual dysfunction and novel interventions for dysphagia. The claim regarding breakthroughs in July 2026 is chronologically unsupported by the provided context, which contains data reaching only through 2025.\n\n### [INTRODUCTION & JUSTIFICATION]\nBulbar palsy manifests as a clinical sign of neuromuscular degeneration, significantly complicating patient outcomes in ALS and GBS. The provided evidence indicates that clinical breakthroughs are primarily centered on non-invasive diagnostic methodologies and nutritional support strategies rather than a singular therapeutic milestone in mid-2026. Quantitative imaging, specifically the use of shear wave elastography and neural network-based tongue volume segmentation, represents a significant shift toward unbiased, objective longitudinal tracking. Furthermore, the standardization of GBS respiratory failure assessment through models like the mEGRIS tool, which integrates bulbar palsy as a high-risk predictor, marks a definitive shift in clinical management. Interventions such as intermittent oro-esophageal feeding and ultrasound-guided stellate ganglion blocks demonstrate that management of secondary symptoms in BP remains the primary area of active research.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Bulbar palsy functions as an independent, high-value predictor for respiratory muscle paralysis in GBS.\n*   Tongue shear wave elastography provides a non-invasive objective metric for correlating bulbar symptom severity with muscle elasticity.\n*   Automated CNN-based segmentation allows for precise monitoring of tongue atrophy in progressive bulbar palsy (PBP) variants.\n*   Intermittent oro-esophageal tube feeding (IOE) significantly reduces complications related to malnutrition and pneumonia compared to traditional nasogastric methods.\n*   Stellate ganglion blocks show promise in improving swallowing function and airway protection by transiently increasing vertebral artery blood flow.\n*   Clinical diagnostic criteria for ALS often require integrated neuroimaging and electrophysiological evaluation to differentiate between PBP and other MND phenotypes.\n*   The inclusion of Platelet-to-Lymphocyte Ratio (PLR) in predictive models for pediatric GBS respiratory failure adds incremental clinical value.\n*   Rare cases of locked-in syndrome (LIS) secondary to vertebral artery dissection demonstrate that bulbar palsy can manifest acutely following mechanical interventions.\n*   Biallelic DNAJC7 mutations establish a genetic pathway linking protein homeostasis, TDP-43 pathology, and PBP.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Recent literature emphasizes a pivot toward objective, non-invasive assessment and targeted, rapid-acting immunomodulation. Advanced diagnostic pipelines now utilize quantitative markers to identify subclinical bulbar involvement, while therapeutic landscapes have expanded to include agents that provide rapid relief in crisis scenarios. These developments represent a departure from purely supportive management toward precision-based neurological intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Efgartigimod and ravulizumab have transitioned into roles as effective bridging or rescue strategies for severe, refractory MG bulbar crisis.\n*   Objective sEMG protocols enable the detection of subclinical bulbar decline, providing a measurement-based framework that is resistant to cognitive-linguistic confounders.\n*   Smartphone-based deep learning (U-Net++ models) offers a scalable, low-barrier diagnostic interface for quantifying tongue motor dysfunction in ALS.\n*   Pyrimidine nucleoside replacement therapy has fundamentally altered the prognosis for infantile-onset TK2 deficiency, enabling milestone recovery previously deemed impossible.\n*   The prevalence of sialorrhea in ALS bulbar-onset cases is increasingly managed through botulinum toxin injection regardless of specific injection technique.\n*   The concept of \"dying back\" of UMN axons in ALS has been refined, with imaging indicating degeneration stops at the brainstem, sparing cortical motor neurons.\n*   The use of PSQI scores to assess sleep quality provides an independent prognostic indicator for bulbar-onset MG and short-term clinical outcomes.\n*   Barium toxicity represents a rare mimic of GBS-like bulbar paralysis, emphasizing the necessity of toxicological screening in unexplained acute paralysis.\n*   Dynamic chest MRI and ultrasound serve as critical objective surrogates for pulmonary function tests in patients where bulbar involvement precludes traditional spirometry.\n*   The presence of LRP4 antibodies characterizes a unique, rare subset of MG coexisting with demyelinating neuropathy, requiring specialized diagnostic panels.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS."

Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov. (Unique identifier: NCT06319534, 20/03/2024)."

This study was a prospective randomized controlled trial. A total of 110 patients with dysphagia due to post-stroke bulbar palsy were enrolled at Baoding No.1 Central Hospital from February 2017 to December 2020. Patients were randomly assigned using a random number table to either a control group (n = 55) receiving conventional pharmacotherapy combined with rehabilitation training, or a treatment group (n = 55) receiving the same conventional therapy plus additional EMG-guided targeted injections of mecobalamin into the swallowing muscles. Swallowing function was assessed using the Wada water swallowing test (WST) and videofluoroscopic swallowing study (VFSS) after 2 weeks of treatment. The treatment group showed a significantly higher overall response rate on the WST than the control group (P < 0.05). Based on VFSS, the marked and overall effectiveness rates were 50.9% and 96.4% in the treatment group, respectively, significantly higher than the corresponding rates of 18.2% and 83.6% in the control group (both P < 0.05). The incidence of aspiration decreased significantly in both groups post-treatment (P < 0.05), with a more pronounced reduction observed in the treatment group (P < 0.05). EMG-guided targeted injection of mecobalamin into swallowing muscles is an effective adjunctive strategy for enhancing swallowing function in patients with dysphagia due to post-stroke medullary paralysis."

A 39-year-old man with bulbar palsy caused by medullary surgery demonstrated impaired pharyngeal contraction and upper esophageal sphincter opening. After undergoing laryngeal suspension and cricopharyngeal myotomy, videofluoroscopic evaluation of swallowing revealed rapid passage of the bolus from the pharynx into the esophagus. High-resolution manometry demonstrated markedly negative intraesophageal pressure accompanied by simultaneous elevation of lower esophageal sphincter pressure during swallowing. These findings suggest that the patient had spontaneously acquired vacuum swallowing despite the presence of a tracheostoma communicating with the atmosphere. Recognition of this compensatory mechanism is important because it may facilitate bolus transport in individuals with tracheostomy. Increased awareness of this swallowing pattern may prevent underdiagnosis and offer new insights into rehabilitation strategies for dysphagia."

Although many patients recover with rehabilitation, some exhibit persistent functional deficits. In such cases, detailed pathophysiologic evaluation may assist in guiding surgical intervention to improve outcomes. A 77-year-old woman presented with severe dysphagia and hoarseness after resection of a right cerebellopontine angle meningioma, which caused glossopharyngeal, vagus, and accessory nerve palsies. Despite initial recovery, she developed repeated aspiration pneumonia and malnutrition. Comprehensive reassessment using high-resolution manometry (HRM) and dynamic swallowing computed tomography (CT) revealed right-sided velopharyngeal insufficiency, pharyngeal constrictor dysfunction, vocal fold paralysis with paramedian fixation, and impaired upper esophageal sphincter relaxation. A tailored multi-procedural surgical approach was performed, including right pharyngeal flap, arytenoid adduction, right hypopharyngeal pharyngoplasty with expanded polytetrafluoroethylene mesh reinforcement, right cricopharyngeal myotomy, and tracheostomy. Postoperatively, swallowing and phonation significantly improved. The patient resumed oral intake, and tracheostoma closure was performed on postoperative day (POD) 25. Maximum phonation time improved sevenfold by POD 32. She was discharged on POD 33, and resumed a regular diet with some limitations by 3 months postoperatively. Intractable dysphagia due to complex LCN dysfunction requires individualized surgical strategies. Multimodal functional assessment, including dynamic swallowing CT and HRM, aids precise evaluation and helps refine surgical planning in selected complex cases, potentially leading to significant improvements in quality of life."

METHODS: Our study analyzed clinical factors linked to pneumonia in GBS patients through a retrospective review of 101 individuals admitted to Tianjin Huanhu Hospital between January 2020 and December 2023. Patients were divided into two groups based on pneumonia development after admission: GBS with pneumonia (n\u2009=\u200919) and GBS without pneumonia (n\u2009=\u200982). Clinical and blood parameters were compared between the groups. Logistic regression analysis identified predictive factors for pneumonia in these GBS patients. RESULTS: Significant associations were found between pneumonia and older age (P\u2009=\u20090.01), bulbar palsy (P\u2009=\u20090.017), mechanical ventilation (MV) support (P\u2009<\u20090.01), hypoalbuminemia (P\u2009<\u20090.01), hyponatremia (P\u2009<\u20090.01), and underlying conditions (P\u2009=\u20090.008). Multivariate logistic regression identified bulbar palsy, MV support and hyponatremia as significant independent risk factors for pneumonia. Finally, GBS patients with pneumonia experienced longer hospital stays and worse functional outcomes. CONCLUSIONS: We initially identified key risk factors for pneumonia in GBS, highlighting its association with poorer prognoses."

Conventional management remains conservative, often yielding unsatisfactory outcomes. We report the case of a 13-year-old girl who developed complete right third cranial nerve palsy following a 15-meter fall, presenting with exotropia (35\u0394), ptosis, complete ophthalmoplegia, and pupillary dysfunction. Brain CT revealed hemorrhage in the right cavernous sinus, and subsequent MRI demonstrated focal nerve damage. Thirty-eight days post-injury, a single botulinum toxin type A (BTX-A) injection (5 units) was administered to the right lateral rectus muscle. Progressive improvement in ocular alignment and motility was observed, with resolution of diplopia by 4.5 months and sustained orthotropia at 10 months post-injury. Although pupillary dilation persisted, functional recovery was substantial. This case demonstrates that early BTX-A intervention may prevent lateral rectus contracture and promote functional recovery in traumatic third cranial nerve palsy. BTX-A represents a promising minimally invasive therapeutic option that warrants further investigation in larger patient populations."

This study assessed the feasibility, safety, and diagnostic performance of a surgeon-controlled, free-hand extraocular muscle electrode placement for corticobulbar motor evoked potentials (cb-MEPs) and direct nerve stimulation (DNS). This monocentric, observational, retrospective study enrolled 40 patients scheduled for skull base tumor surgery, with planned intraoperative monitoring of CN III and/or VI. Curved needle electrodes were placed free-hand by the neurosurgeon at the scleral\u2013muscular junction of the medial and/or lateral rectus, and cb-MEPs and DNS were recorded; evaluability required reproducible baselines. Primary endpoint was 3-month cranial nerve palsy. Diagnostic accuracy was calculated, and Spearman correlations tested the relationship between intraoperative percentage amplitude change and postoperative deficit severity. Placement succeeded in all cases (mean 10 min) with one transient conjunctivitis (2.5%). Stable baseline cb-MEPs occurred in 20/37 (CN III) and 18/31 (CN VI). For CN III, cb-MEPs showed sensitivity 66.7% and specificity 100%; amplitude reduction correlated with postoperative severity (\u03c1\u2009=\u20090.94, p\u2009<\u20090.001).

DNS elicited responses in 15/22, with sensitivity 75.0% and specificity 100%. This neurosurgeon-performed, free-hand technique enabled rapid, safe, and reproducible electrode placement for extraocular cranial nerve monitoring during skull base surgery.

Clinicians must remain vigilant for neuroinvasive illness in patients presenting with febrile symptoms and malaise following mosquito exposure. While magnetic resonance imaging and cerebrospinal fluid analysis aid in differential diagnosis, detecting West Nile immunoglobulin M in serum is crucial for definitive diagnosis. Treatment primarily involves supportive care due to the absence of established regimens, though promising outcomes have been reported with plasma exchange and intravenous immunoglobulin. We present the case of an 83-year-old resident of Alabama, an avid gardener living near a pond, who initially exhibited symptoms of productive cough, diarrhea, fever, and generalized malaise. However, within 48 h, he developed hypoxemia, functional quadriplegia, and bulbar palsy necessitating intubation. Diagnostic evaluations, including magnetic resonance imaging and positive West Nile virus immunoglobulin M in serum, confirmed West Nile virus-associated poliomyelitis viral syndrome, prompting intravenous immunoglobulin therapy. This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions.

Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group.

The claim of \"breakthroughs\" is supported by evidence demonstrating novel therapeutic interventions, improved diagnostic methodologies, and prognostic stratification tools, specifically within the contexts of stroke rehabilitation, degenerative motor neuron disorders, and immune-mediated neuropathies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of bulbar palsy has evolved significantly, shifting from strictly supportive care toward targeted, mechanism-based therapeutic strategies. Recent literature emphasizes the utility of ultrasound-guided interventions, such as stellate ganglion blocks, and electromyography-guided pharmacological injections to enhance swallowing efficacy. In the realm of degenerative conditions, the significance of early genetic testing and sustained riboflavin supplementation in disorders like Brown-Vialetto-Van Laere syndrome highlights a transition toward precision medicine. Furthermore, diagnostic innovations\u2014such as tongue shear wave elastography\u2014provide non-invasive, quantitative data for bulbar dysfunction in motor neuron diseases. These developments collectively signify a multidimensional approach to improving patient quality of life through enhanced pharyngeal mechanics and early diagnostic awareness.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Electromyography-guided targeted injections of mecobalamin represent a significant shift toward individualized pharmacotherapy for post-stroke bulbar palsy.\n*   Ultrasound-guided stellate ganglion block provides a safe, reproducible, and long-term functional improvement in swallowing function post-stroke, despite temporary effects on vertebral artery blood flow.\n*   Tongue shear wave elastography has emerged as a quantitative biomarker to non-invasively assess genioglossus muscle elasticity in bulbar-onset ALS.\n*   Spontaneous \"vacuum swallowing\" is a compensatory mechanism in patients with tracheostomy that, if recognized, can be harnessed for swallowing rehabilitation.\n*   Stellate ganglion blocks address both motor function (swallowing) and psychological status (anxiety) in bulbar-palsy patients.\n*   Bulbar palsy is confirmed as a significant, independent risk factor for the development of pneumonia in GBS patients.\n*   Early identification of bulbar palsy acts as a critical prognostic indicator for short-term outcomes in severe GBS cases.\n*   The use of botulinum toxin type A in pediatric traumatic third nerve palsy demonstrates how early intervention can prevent long-term sequelae through neural plasticity and muscle preservation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Neurological examination revealed lower\u2011extremity weakness with areflexia, bulbar involvement causing stridor, unilateral facial weakness, and gait ataxia (Hughes score 4). Cerebrospinal fluid analysis showed albumin\u2011cytologic dissociation, and nerve conduction studies demonstrated acute inflammatory demyelinating polyradiculoneuropathy. Given the rapid progression and severity, therapeutic plasma exchange (PE) was administered (five exchanges over 10\u00a0days) along with supportive care. Strength improved steadily, and at 1\u00a0month she was able to walk and run independently (Hughes score 0). This case expands the limited pediatric literature on malaria-associated GBS and highlights the importance of recognizing evolving bulbar and neurological symptoms after Plasmodium falciparum infection. Early supportive care and immunotherapy may contribute to favorable neurological recovery.\n\nID: 42316955\nTitle: Postinfectious polyneuritis cranialis: A case report.\nAbstract: Polyneuritis cranialis is characterized by the simultaneous or sequential inflammation of multiple cranial nerves, which may occur unilaterally or bilaterally. Although it is often related to infection, its exact etiology remains unclear. Due to its nonspecific clinical manifestations, diagnosis typically relies on the exclusion of other conditions. Herein, we report a case of postinfectious polyneuritis cranialis. The patient presented to our hospital with restricted mouth opening, dysphagia, coughing while drinking, dysarthria, and posterior neck pain following a finger injury. Laboratory tests showed markedly elevated inflammatory markers. Neurological examination revealed involvement of cranial nerves V, IX, X, and XII. Motor nerve conduction studies of the facial nerve suggested partial facial nerve damage. Brain magnetic resonance imaging demonstrated mild nonspecific white matter changes. After exclusion of alternative diagnoses, the patient was diagnosed with polyneuritis cranialis. The patient's condition improved following corticosteroid pulse therapy and was subsequently discharged. This case highlights that the diagnosis of polyneuritis cranialis remains one of exclusion and is often clinically challenging. When encountering patients with rapidly progressive cranial nerve palsies, polyneuritis cranialis should be included in the differential diagnosis after more common structural or systemic etiologies have been excluded.\n\nID: 42293075\nTitle: Efficacy observation of electromyography-guided targeted injection of swallowing muscles for treating dysphagia resulting from medullary paralysis.\nAbstract: To observe the clinical efficacy of electromyography (EMG)-guided targeted mecobalamin injections for treating dysphagia resulting from medullary paralysis and to investigate effective dysphagia management strategies. This study was a prospective randomized controlled trial. A total of 110 patients with dysphagia due to post-stroke bulbar palsy were enrolled at Baoding No.1 Central Hospital from February 2017 to December 2020. Patients were randomly assigned using a random number table to either a control group (n = 55) receiving conventional pharmacotherapy combined with rehabilitation training, or a treatment group (n = 55) receiving the same conventional therapy plus additional EMG-guided targeted injections of mecobalamin into the swallowing muscles. Swallowing function was assessed using the Wada water swallowing test (WST) and videofluoroscopic swallowing study (VFSS) after 2 weeks of treatment. The treatment group showed a significantly higher overall response rate on the WST than the control group (P < 0.05). Based on VFSS, the marked and overall effectiveness rates were 50.9% and 96.4% in the treatment group, respectively, significantly higher than the corresponding rates of 18.2% and 83.6% in the control group (both P < 0.05). The incidence of aspiration decreased significantly in both groups post-treatment (P < 0.05), with a more pronounced reduction observed in the treatment group (P < 0.05). EMG-guided targeted injection of mecobalamin into swallowing muscles is an effective adjunctive strategy for enhancing swallowing function in patients with dysphagia due to post-stroke medullary paralysis.\n\nID: 42056474\nTitle: SLC52A3-related Brown-Vialetto-Van Laere syndrome: a large cohort from the Arabian Peninsula.\nAbstract: SLC52A3-related Brown-Vialetto-Van Laere syndrome (BVVL) is a rare neurodegenerative disorder characterized by progressive motor and sensory impairment, with high mortality rate if left untreated. We hereby report the largest cohort with SLC52A3-related BVVL from the Arabian Peninsula. A total of 23 patients, 16 females and 7 males, with genetically confirmed BVVL diagnosis at two tertiary centers from the region were retrospectively\u00a0reviewed. Most patients were clinically ascertained (13/23), while 10 patients were diagnosed pre-symptomatically. 20 patients were homozygous for SLC52A3: c.634C>T (p.Arg212Cys) variant and 3 patients were homozygous for SLC52A3: c.1325_1326del. Facial diplegia was the commonest clinical feature (12/13), while moderate to severe hearing loss and dysarthria were seen in (10/13) patients. Symptomatic patients were treated with riboflavin doses ranging between 15 and 100\u2009mg/Kg/day, with a median of 26\u2009mg/Kg/day. Pre-symptomatic patients were treated with doses lower than that (as low as 5\u2009mg/Kg/day). Patients were followed for 6 months to 12 years, with a median of 4 years. Most patients have shown significant or near-total recovery with residual symptoms (11/13), while 9/10 patients diagnosed pre-symptomatically remained symptom-free, and 2 symptomatic patients showed complete resolution of symptoms. The study emphasizes the significant interfamilial and intrafamilial variability of BVVL, and it stresses the impact of early treatment with riboflavin in the prevention of morbidity and mortality associated with this condition. The study also provides the longest cumulative follow-up of pre-symptomatically treated patients reported to date, providing preliminary evidence for the role of riboflavin in the prevention of morbidities associated with this condition.\n\nID: 41907206\nTitle: ANCA-Associated Vasculitis with Predominant Peripheral and Central Nervous System Involvement: A Case Report.\nAbstract: ANCA-associated vasculitis (AAV) is an immune-mediated multi-system disease. It can present with neurological involvement as its predominant manifestation. We report a case of AAV with predominant peripheral and central nervous system involvement. A 62-year-old male presented with fever and asymmetric weakness and pain in the lower limbs. Electrophysiological studies revealed asymmetric axonal damage in both lower limbs. During hospitalization, he developed acute bulbar palsy. Brain MRI confirmed bilateral basal ganglia infarction. Ancillary tests indicated involvement of the lungs, kidneys, and hematological systems, along with positive MPO-ANCA (p-ANCA), confirming the diagnosis of AAV. His symptoms gradually improved following treatment with glucocorticoids and immunosuppressants. At the 6-month follow-up, his symptoms were largely resolved. The presence of asymmetric axonal neuropathy or atypical non-atherosclerotic cerebral infarction, particularly when accompanied by multisystem involvement, should raise suspicion for AAV. Early diagnosis and prompt treatment significantly improve patient outcomes.\n\nID: 41782152\nTitle: Effects of ultrasound-guided stellate ganglion block in poststroke bulbar palsy: a double-blind placebo-controlled trial.\nAbstract: Bulbar palsy typically causes severe dysphagia. Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov.

METHODS: Our study analyzed clinical factors linked to pneumonia in GBS patients through a retrospective review of 101 individuals admitted to Tianjin Huanhu Hospital between January 2020 and December 2023. Patients were divided into two groups based on pneumonia development after admission: GBS with pneumonia (n\u2009=\u200919) and GBS without pneumonia (n\u2009=\u200982). Clinical and blood parameters were compared between the groups. Logistic regression analysis identified predictive factors for pneumonia in these GBS patients. RESULTS: Significant associations were found between pneumonia and older age (P\u2009=\u20090.01), bulbar palsy (P\u2009=\u20090.017), mechanical ventilation (MV) support (P\u2009<\u20090.01), hypoalbuminemia (P\u2009<\u20090.01), hyponatremia (P\u2009<\u20090.01), and underlying conditions (P\u2009=\u20090.008). Multivariate logistic regression identified bulbar palsy, MV support and hyponatremia as significant independent risk factors for pneumonia. Finally, GBS patients with pneumonia experienced longer hospital stays and worse functional outcomes. CONCLUSIONS: We initially identified key risk factors for pneumonia in GBS, highlighting its association with poorer prognoses.\n\nID: 41328116\nTitle: An Atypical Descending Variant of Guillain-Barr\u00e9 Syndrome With Bulbar Palsy, Autonomic Instability, and Delayed Colonic Pseudo-Obstruction: A Case Report.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is an acute, immune-mediated polyradiculoneuropathy that is the most common cause of acute flaccid paralysis worldwide. The classical form manifests as an ascending, symmetrical weakness, but atypical variants, including descending presentations, have been increasingly recognized. Such variants often pose diagnostic challenges and are associated with more severe disease and prolonged recovery. We describe a 70-year-old woman with well-controlled hypertension who presented with progressive dysphagia, pooling of saliva, and upper limb weakness. Clinical examination revealed bulbar dysfunction, areflexia in the upper limbs, and motor power in the upper limbs was markedly reduced to grade 1/5 on the Medical Research Council (MRC) scale, while lower limb strength was preserved. Within hours of admission, the weakness progressed to quadriplegia with respiratory distress, necessitating intubation and mechanical ventilation. Cerebrospinal fluid analysis demonstrated albumin cytological dissociation, and nerve conduction studies revealed changes consistent with GBS. Intravenous immunoglobulin was initiated but discontinued due to anaphylaxis; therapeutic plasma exchange was subsequently performed. The patient had marked cardiovascular lability and, after one month, acute colonic pseudo-obstruction (ACPO), which resolved with conservative management. Around the 40th day, she experienced complete left lung collapse due to mucus plugging, which was successfully managed with bedside bronchoscopy. Persistent bulbar dysfunction delayed decannulation until day 80. Remarkably, full neurological recovery was achieved only after six months of follow-up. This case highlights several atypical and severe features of GBS: descending onset with bulbar involvement at presentation, multisystem autonomic dysfunction extending to the gastrointestinal tract, and a protracted course despite early immunotherapy and supportive care. The unusually delayed onset of ACPO and persistent bulbar palsy underscores the need for vigilance beyond the acute phase. Hence, clinicians should maintain a high index of suspicion for atypical variants of GBS in patients with acute, progressive weakness, even when the presentation deviates from the classical ascending pattern. A structured, multimodal diagnostic approach and timely initiation of therapy are essential to prevent complications. Severe variants may follow a prolonged recovery trajectory, requiring sustained multidisciplinary management.\n\nID: 41285215\nTitle: Altered dimerization of certain riboflavin transporter 2 mutants: a possible source of UPR, altered calcium signalling and mitochondrial derangements in RTD2.\nAbstract: Riboflavin transporter deficiency Type 2 (RTD2, OMIM #614707), formerly known as Brown-Vialetto-Van Laere Syndrome 2 (BVVLS 2), is a rare autosomal recessive neurodegenerative disorder caused by biallelic variants in the SLC52A2 gene, encoding for riboflavin transporter 2 (RFVT2). This transporter plays a critical role in flavin cofactor delivery, particularly in the brain. Clinically, RTD2 presents with progressive hearing loss, optic atrophy, muscle weakness, respiratory issues, and pontobulbar palsy. Current treatment involves high-dose riboflavin and other supplements. In this study we explored the molecular mechanisms behind RTD2, focusing on the dimerization of RFVT2 and the associated cellular stress mechanisms in patient-specific models. We demonstrated that RFVT2 exists as a homodimer and that pathogenic variants significantly impair its dimerization, which may contribute to the induction of ER stress. This hypothesis was supported by elevated levels of BiP, an ER stress marker, in patient iPSC-derived motor neurons. Similar findings were confirmed in patient-derived fibroblasts, where we also observed mitochondrial dysfunction and disrupted calcium signaling. Interestingly, no significant changes in FAD content were detected in both cell models, suggesting that proteotoxic stress may be a crucial pathogenic mechanism in RTD2, even in the absence of signs of FAD deficiency. FAD autofluorescence and FLIM measurements reinforce the occurrence of mitochondrial dysfunction in patient MNs. These findings provide insight into the pathogenic mechanisms of RTD2, highlighting the critical role of RFVT2 misfolding, ER stress, and mitochondrial dysfunction in this neurodegenerative disorder.\n\nID: 41241894\nTitle: Rapid Bolus Inflow into the Esophagus in a Patient with a Tracheostomy after Surgical Treatment for Dysphagia.\nAbstract: This report describes a case in which a patient with an open tracheostomy, following surgery for severe dysphagia, acquired vacuum swallowing and exhibited rapid bolus inflow into the esophagus. A 39-year-old man with bulbar palsy caused by medullary surgery demonstrated impaired pharyngeal contraction and upper esophageal sphincter opening. After undergoing laryngeal suspension and cricopharyngeal myotomy, videofluoroscopic evaluation of swallowing revealed rapid passage of the bolus from the pharynx into the esophagus. High-resolution manometry demonstrated markedly negative intraesophageal pressure accompanied by simultaneous elevation of lower esophageal sphincter pressure during swallowing. These findings suggest that the patient had spontaneously acquired vacuum swallowing despite the presence of a tracheostoma communicating with the atmosphere. Recognition of this compensatory mechanism is important because it may facilitate bolus transport in individuals with tracheostomy. Increased awareness of this swallowing pattern may prevent underdiagnosis and offer new insights into rehabilitation strategies for dysphagia.\n\nID: 41090254\nTitle: A Case of Miller-Fisher Overlap Syndrome With Positive Anti-GM4 Antibody and Atypical Symptoms.\nAbstract: Miller-Fisher syndrome (MFS) is a recognized clinical variant of Guillain-Barr\u00e9 syndrome (GBS), characterized by the classic triad of ophthalmoplegia, ataxia, and areflexia. When accompanied by additional symptoms such as bulbar palsy, limb weakness, or lethargy, it is termed MFS overlap syndrome. This report describes a male patient diagnosed with MFS overlap syndrome, presenting with ophthalmoplegia, ataxia, bulbar palsy, numbness in both arms, positive GM4 IgG antibodies, a persistent, intractable headache, and a delayed onset of left-sided peripheral facial palsy. The patient had a preceding suspected case of chlamydial pneumonia before symptom onset, and his condition improved significantly following treatment with intravenous immunoglobulin. This case suggests that chlamydial pneumonia might predispose individuals to GBS. Patients with MFS/pharyngeal-cervical-brachial (PCB) overlap syndrome may exhibit atypical symptoms, including persistent, intractable headaches, and delayed peripheral facial paralysis. Atypical symptoms should not delay the diagnosis and treatment of GBS once other conditions have been adequately excluded. The presence of anti-GM4 antibodies, often found alongside other anti-ganglioside antibodies, may serve as a critical immunological factor in MFS/PCB overlap syndrome.\n\nID: 41060834\nTitle: Atypical phenotypic characteristics, mutation analysis and treatment in a family of riboflavin transporter deficiency caused by SLC52A3 variants.\nAbstract: Variants in the SLC52A3 gene have been associated with riboflavin transporter deficiency type 3 (RTD3), a severe neurodegenerative disorder, typically inherited in an autosomal recessive manner. In this study, two SLC52A3 variants (NM_033409.4: c.62A\u2009>\u2009G [p.Asn21Ser] and c.161G\u2009>\u2009A [p.Gly54Glu]) were identified in a family with hereditary hearing loss through whole-exome sequencing. The compound heterozygous proband exhibited only late-onset, progressive, and symmetric sensorineural hearing loss over 23\u00a0yr, along with unilateral facial muscle spasm. A heterozygous carrier of the c.62A\u2009>\u2009G variant also exhibited optic nerve dysfunction, while no other neurological abnormalities were observed in the family. Although the proband's decreased serum riboflavin level has been improved through supplementation, no significant clinical improvement was observed. These findings further support the phenotypic variability, incomplete penetrance, and a potential autosomal dominant inheritance pattern of RTD3. We also underscore the importance of early genetic testing, timely and sustained riboflavin supplementation, and long-term follow-up in affected individuals.\n\nID: 41004918\nTitle: Tongue shear wave elastography for bulbar dysfunction in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often manifests with tongue involvement, leading to dysarthria and dysphagia. While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS.\n\nID: 40962541\nTitle: [Clinical analysis of anti-GT1a antibody-positive Guillain-Barr\u00e9 syndrome in 25 children].\nAbstract: Objective: To summarize the clinical characteristics, treatment, and prognosis of children with anti-GT1a antibody-positive Guillain-Barr\u00e9 syndrome (GBS). Methods: A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children's Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results: A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71\u00b18) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23\u00b13) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge (Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions: Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment. \u76ee\u7684\uff1a \u603b\u7ed3\u513f\u7ae5\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u7684\u4e34\u5e8a\u7279\u70b9\u3001\u6cbb\u7597\u53ca\u9884\u540e\u3002 \u65b9\u6cd5\uff1a \u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\uff0c\u9009\u62e92019\u5e743\u6708\u81f32024\u5e7412\u6708\u5728\u5e7f\u5dde\u533b\u79d1\u5927\u5b66\u9644\u5c5e\u5987\u5973\u513f\u7ae5\u533b\u7597\u4e2d\u5fc3\u795e\u7ecf\u5185\u79d1\u4e34\u5e8a\u8bca\u65ad\u4e3a\u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u768425\u4f8b\u60a3\u513f\uff0c\u6536\u96c6\u5e76\u5206\u6790\u5176\u4e34\u5e8a\u8d44\u6599\u53ca\u6cbb\u7597\u968f\u8bbf\u8d44\u6599\u3002\u91c7\u7528Mann-Whitney U\u68c0\u9a8c\u6bd4\u8f83\u60a3\u513fHughes\u529f\u80fd\u5206\u7ea7\u8bc4\u5206\uff08HFGS\uff09\u53d8\u5316\u3002 \u7ed3\u679c\uff1a 25\u4f8b\u60a3\u513f\u753712\u4f8b\u3001\u597313\u4f8b\uff0c\u9996\u6b21\u53d1\u75c5\u5e74\u9f84\u4e3a\uff0871\u00b18\uff09\u6708\u9f84\u300216\u4f8b\uff0864%\uff09\u6709\u524d\u9a71\u611f\u67d3\uff0c\u5176\u4e2d13\u4f8b\u4e3a\u547c\u5438\u9053\u611f\u67d3\u3002\u75be\u75c5\u9ad8\u5cf0\u65f6\u795e\u7ecf\u7cfb\u7edf\u75c7\u72b6\u5305\u62ec\u80a2\u4f53\u65e0\u529b21\u4f8b\uff0884%\uff09\u3001\u7403\u9ebb\u75f913\u4f8b\uff0852%\uff09\u3001\u55dc\u77617\u4f8b\uff0828%\uff09\u3001\u80a2\u4f53\u75bc\u75db9\u4f8b\uff0836%\uff09\u3001\u5171\u6d4e\u5931\u8c036\u4f8b\uff0824%\uff09\u3001\u547c\u5438\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u773c\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u5355\u4fa7\u9762\u795e\u7ecf\u9ebb\u75f94\u4f8b\uff0816%\uff09\u300223\u4f8b\u60a3\u513f\u8111\u810a\u6db2\u68c0\u67e5\uff0c\u86cb\u767d-\u7ec6\u80de\u5206\u79bb18\u4f8b\u300225\u4f8b\u60a3\u513f\u5168\u810a\u67f1\u78c1\u5171\u632f\u6210\u50cf\uff08MRI\uff09\u68c0\u67e5\u793a\u810a\u795e\u7ecf\u6839\u5f3a\u531618\u4f8b\uff0c\u67d4\u8111\u819c\u5f3a\u5316\u5408\u5e76\u810a\u795e\u7ecf\u6839\u5f3a\u53161\u4f8b\u300216\u4f8b\u60a3\u513f\u63a5\u53d7\u808c\u7535\u56fe\u68c0\u67e5\uff0c15\u4f8b\u5f02\u5e38\uff0c\u5176\u4e2d\u8131\u9ad3\u9798\u75c5\u53d88\u4f8b\u3001\u8131\u9ad3\u9798\u5408\u5e76\u8f74\u7d22\u75c5\u53d84\u4f8b\uff0c\u8f74\u7d22\u75c5\u53d83\u4f8b\u3002\u9759\u8109\u8f93\u6ce8\u514d\u75ab\u7403\u86cb\u767d\uff08IVIG\uff09\u6cbb\u7597 21\u4f8b\uff0884%\uff09\uff0c\u5176\u4e2d3\u4f8b\u60a3\u513fIVIG\u6cbb\u7597\u540e\u75c5\u60c5\u8fdb\u5c55\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\u884c\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u53ca\u8840\u6db2\u51c0\u5316\u6cbb\u7597\uff0c\u5305\u62ec\u8840\u6d46\u7f6e\u63622\u4f8b\u3001\u514d\u75ab\u5438\u9644\u6cbb\u75971\u4f8b\u30024\u4f8b\u60a3\u513f\u62d2\u7eddIVIG\u6cbb\u7597\u63a5\u53d7\u9759\u8109\u8f93\u6ce8\u7532\u6cfc\u5c3c\u9f99\uff08IVMP\uff09\u6cbb\u7597\uff0c\u5176\u4e2d1\u4f8b\u56e0\u547c\u5438\u808c\u9ebb\u75f9\u63a5\u53d7\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u6cbb\u7597\uff0c\u7ee7\u7eedIVMP\u5e8f\u8d2f\u6cbb\u7597\u540e\u62d4\u9664\u6c14\u7ba1\u63d2\u7ba1\u300225\u4f8b\u60a3\u513f\u9996\u6b21\u53d1\u75c5\u6025\u6027\u671f\u7684\u4f4f\u9662\u65f6\u95f4\u4e3a\uff0823\u00b13\uff09d\uff0c\u51fa\u9662\u65f6HFGS 1.6\uff080.6\uff0c2.7\uff09\u5206\uff0c\u9996\u6b21\u53d1\u75c5\u51fa\u9662\u81f3\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u7684\u65f6\u95f4\u95f4\u9694\u4e3a12\uff084\uff0c18\uff09\u4e2a\u6708\uff0cHFGS 0.1\uff080.0\uff0c0.5\uff09\u5206\uff0c\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u65f6HFGS\u4f4e\u4e8e\u51fa\u9662\u65f6\uff08Z=4.38\uff0cP<0.05\uff09\u30022\u4f8b\u60a3\u513f\u590d\u53d1\uff0c\u518d\u6b21\u4e88IVIG\u6cbb\u7597\u540e\u7f13\u89e3\uff0c\u968f\u8bbf1\u5e74\u672a\u518d\u590d\u53d1\u3002 \u7ed3\u8bba\uff1a \u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u6025\u6027\u671f\u5e38\u89c1\u7684\u75c7\u72b6\u4e3a\u80a2\u4f53\u65e0\u529b\u53ca\u7403\u9ebb\u75f9\uff0c\u4e25\u91cd\u8005\u53ef\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\uff0c\u808c\u7535\u56fe\u4ee5\u8131\u9ad3\u9798\u75c5\u53d8\u591a\u89c1\uff0cMRI\u810a\u795e\u7ecf\u6839\u5316\u5e38\u89c1\uff0c\u591a\u6570\u60a3\u513fIVIG\u514d\u75ab\u6cbb\u7597\u6548\u679c\u826f\u597d\uff0c\u65e0\u4e25\u91cd\u795e\u7ecf\u7cfb\u7edf\u540e\u9057\u75c7\u6b8b\u7559\u3002\u5c11\u6570\u60a3\u513f\u53ef\u80fd\u590d\u53d1\u3002.\n\nID: 40918919\nTitle: Utility of Breath-Holding Time in Monitoring Acute Neuromuscular Respiratory Failure in Bulbar-Onset Myasthenia Gravis: A Case Report.\nAbstract: We report the management of a 64-year-old male with newly diagnosed bulbar-onset myasthenia gravis (MG) who was hospitalized with acute neuromuscular respiratory insufficiency. This case highlights the challenges in monitoring respiratory function in MG patients, especially in the presence of bulbar and nuchal weakness, and emphasizes the potential utility of single breath-hold time (SBHT) over forced vital capacity (FVC) as a reliable bedside monitoring tool. Despite initial stabilization with intravenous immunoglobulin (IVIG), the patient deteriorated, requiring escalation to the intensive care unit (ICU), and the clinical worsening corresponded with the SBHT rather than with FVC.\n\nID: 40913874\nTitle: A case report on Ayurvedic management of progressive bulbar palsy-A rare amyotrophic lateral sclerosis phenotype.\nAbstract: This case report is the description of a devastating illness, Progressive Bulbar Palsy (PBP) of a sixty-seven years old male patient. He presented with complaints of slurred speech, hearing impairment, generalised weakness of limbs, weakened grip to hold objects in hand, difficulty to walk with normal speed, frequent dizzy feeling while walking, severe fatigue, increased anger, heaviness of head, depression, anxiety, decreased memory and headache for 1 year. When he consulted conventional medicine, in Magnetic Resonance Imaging (MRI) of brain, only 'Partial empty sella' and age related mild cerebral atrophy was detected and the patient was diagnosed PBP clinically. They prescribed Riluzole 50 mg tablet twice a day and Fluoxetine 10mg capsules at night time for 3 months, but obtained no relief for symptoms and consulted this Out Patient Department (OPD). In Ayurvedic parlance, PBP resembles conditions like Kaphavruta vata. In this patient, Pittavritavata symptoms like bhrama (\u223cdizziness) was also present in increased severity. Diagnosis was done with the aid of Gold Coast diagnostic criteria. Internal and external medications with properties alleviating avarana (\u223cocclusion) of vata by kapha and pitta, shodhana (\u223cexpelling the aggravated doshas and cleanses the body internally), rejuvenating (Rasayana) properties, for overall strengthening of nervous system and musculoskeletal system, enhancing balance and coordination, improving speech and memory were used. The assessment was done before and after the treatment by 'Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). The score before and after the treatment was 35 and 45 respectively out of 48. The treatment helped to increase the quality of life exceptionally as symptomatic relief was obtained. As it is a devastating disorder with poor prognosis and most probably will lead to death, it is advisable to repeat the treatments in regular intervals, depending on the recurrence of symptoms, if any.\n\nID: 40901171\nTitle: Acquired hemophilia a in a female with minimal change disease and hypothyroidism: a rare case report.\nAbstract: Juvenile amyotrophic lateral sclerosis (J-ALS) is extremely rare neurodegenerative motor neuron disorder that begins in early childhood or adolescence, before the age of 25\u00a0years old. It is characterized by gradual disease progression with comparison to adult-onset ALS and is often linked to genetic mutations. A 16-years-old female presented with long history of generalized weakness since age of 10 years, followed by bilateral sensorineural hearing loss, bulbar symptoms, and limb spasticity. Neurological examination revealed upper motor neuron signs in upper limbs, lower motor neuron signs in lower limbs, and bulbar involvement. Nerve conduction test was normal however, MRI showed early degenerative changes, and diagnosed with J-ALS after careful evaluation. She was started on Riluzole. Despite ICU care and supportive interventions including PEG and tracheostomy, she succumbed to respiratory failure. Rarity, atypical presentation, and finical constraints can delay diagnosis of J-ALS. However, early diagnosis after careful evaluation of clinical symptoms, medical history, electrophysiological and imaging studies followed by prompt treatment with Riluzole and supportive interventions can help prolong survival and improve quality of life. J-ALS is a rare motor neuron disease which possess immense diagnostic challenges, can exhibit relentless progression over short period of time with time.\n\nID: 40825554\nTitle: [Myasthenia Gravis Treated with Zilucoplan Prior to Extended Transsternal Thymectomy for the Prevention of Myasthenic Crisis: A Case Report].\nAbstract: A 50year-old female was diagnosed with myasthenia gravis (MG) following aspiration pneumonia. Despite treatment with prednisolone (5mg/day) and intravenous immunoglobulin (IVIg), the bulbar palsy persisted. Additionally, chest CT revealed findings suggestive of invasive thymoma or thymic carcinoma, leading to a planned thymectomy with median sternotomy. This case presents a high-risk of myasthenic crisis due to thymoma-associated MG, persistent bulbar palsy, and the need for highly invasive surgery. Therefore, enhanced immunotherapy was required to prevent this crisis, and zilucoplan was chosen because of its rapid onset of action and compatibility with IVIg. Following the initiation of zilucoplan, there was prompt improvement in the symptoms of MG. Effective preoperative control of MG led to a good clinical course, with no significant postoperative myasthenic crisis or exacerbation of symptoms. This is the first report on the use of zilucoplan for the prevention of perioperative myasthenic crisis. (Received April 14, 2025; Accepted June 3, 2025, Published August 1, 2025).\n\nID: 40764927\nTitle: Rhombencephalitis associated with varicella-zoster virus masquerading as Guillain-Barr\u00e9 syndrome.\nAbstract: Although rare, rhombencephalitis or inflammation of the brainstem and cerebellum has significantly associated morbidity and mortality. We describe the case of a 64-year-old previously healthy, immunocompetent man who presented with acute bulbar symptoms (difficulty swallowing, change in phonation, and drooling). His symptoms progressed in severity and he ultimately required intubation due to declining lung function and inability to manage his secretions. Clinical examination revealed bulbar dysfunction without involvement of other cranial nerves. A lumbar puncture revealed albuminocytological dissociation: elevated protein (9.8\u00a0g/L), nonerythroid cell count (13 cells/\u00b5L) with predominantly lymphocytic count. He received a five-day course of intravenous immunoglobulin for presumed Guillain-Barr\u00e9 syndrome. Initial magnetic resonance imaging (MRI) showed mild microangiopathic changes in the brain with no parenchymal, leptomeningeal, or cranial nerve enhancement. Cerebrospinal fluid (CSF) analysis was positive for varicella zoster virus (VZV). He was treated with intravenous Acyclovir 10\u00a0mg/kg three times daily for 14 days with no initial improvement and underwent a tracheostomy. Subsequent MRI was consistent with rhombencephalitis. VZV rhombencephalitis with cranial neuropathies represents a rare and potentially fatal condition. Early recognition and investigation with lumbar puncture and imaging are critical for establishing the diagnosis and initiating treatment.\n\nID: 40628688\nTitle: Worster-Drought syndrome with progressive symptomatic improvement in early infancy.\nAbstract: Worster-Drought syndrome (WDS), or congenital suprabulbar paresis, is characterised by congenital dysarthria, dysphagia and other pseudobulbar paresis without structural abnormalities around the Sylvian fissure on imaging. This rare syndrome is challenging to diagnose, particularly in preterm infants. This report describes a low-birth-weight female infant with WDS who had no sucking reflex from birth, airway obstruction due to saliva retention and muscle rigidity, who was diagnosed with the syndrome at a postconceptional age (PCA) of 1\u2009month. She was discharged with only home oxygen therapy as respiratory support at a PCA of 3 months after gradual improvement in her clinical symptoms. Diagnosis of WDS is difficult in the early postnatal period in preterm cases owing to prematurity but should be suspected when bulbar palsy, including absence of the sucking reflex, persistent dysphagia and obstructed breathing, persists beyond a PCA of 40 weeks and when muscle stiffness is present.\n\nID: 40567532\nTitle: West Nile neuroinvasive disease with poliomyelitis syndrome: A grave phenomenon.\nAbstract: West Nile virus infection poses a significant threat, especially during the warmer months when mosquitoes are abundant. Clinicians must remain vigilant for neuroinvasive illness in patients presenting with febrile symptoms and malaise following mosquito exposure. While magnetic resonance imaging and cerebrospinal fluid analysis aid in differential diagnosis, detecting West Nile immunoglobulin M in serum is crucial for definitive diagnosis. Treatment primarily involves supportive care due to the absence of established regimens, though promising outcomes have been reported with plasma exchange and intravenous immunoglobulin. We present the case of an 83-year-old resident of Alabama, an avid gardener living near a pond, who initially exhibited symptoms of productive cough, diarrhea, fever, and generalized malaise. However, within 48 h, he developed hypoxemia, functional quadriplegia, and bulbar palsy necessitating intubation. Diagnostic evaluations, including magnetic resonance imaging and positive West Nile virus immunoglobulin M in serum, confirmed West Nile virus-associated poliomyelitis viral syndrome, prompting intravenous immunoglobulin therapy. This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions. The case also begs the question of the timing and efficacy of intravenous immunoglobulin and plasma exchange in West Nile virus infection and the fact that more data should be collected on these therapies.\n\nID: 40539137\nTitle: Long-Term Survival in Brown-Vialetto-Van Laere Syndrome: A Case Report Highlighting Respiratory Care.\nAbstract: Brown-Vialetto-Van Laere syndrome (BVVLS) is an extremely rare genetic neurological disorder caused by riboflavin transport deficiency, an autosomal recessive condition mostly\u00a0associated with mutations in the SLC52A2 and SLC52A3 genes. It follows a progressive course, typically characterized by sensorineural deafness, facial weakness, ponto-bulbar palsy, ataxia, and peripheral sensory-motor neuropathy. This disease is\u00a0often associated with childhood mortality if left untreated.\u00a0We report the case of a 68-year-old woman who first noticed a mild hearing loss at the age of 12. This was followed by a slowly progressive onset of bilateral facial paresis, dysarthro-dysphonia, stridor, and tongue atrophy with fasciculations. At 63 years of age, genetic testing revealed a single heterozygous variant in the SLC52A3 gene.\u00a0Although typically autosomal recessive,\u00a0some individuals with classic symptoms and even response\u00a0to riboflavin therapy have been found to carry only a single mutation in either the SLC52A2 or SLC52A3 gene. Therefore, given the\u00a0compatible clinical presentation, a diagnosis of\u00a0BVVLS was considered after discussion with a center of expertise.\u00a0Consequently,\u00a010 mg/kg/day of riboflavin supplementation\u00a0was prescribed for three years, but no significant clinical improvement was observed. Currently, at age 68, the patient is on nocturnal non-invasive mechanical ventilation (NIV)\u00a0and uses assisted airway clearance techniques, including air-stacking maneuvers and mechanical insufflation-exsufflation on demand, due to respiratory compromise secondary to diaphragmatic weakness and vocal cord paralysis. This unique presentation of slowly progressive symptoms and long survival may be related to the single heterozygous SLC52A3 variant found. Respiratory care in BVVLS is currently adapted from other neuromuscular disorders with stronger evidence bases.\u00a0This case highlights the critical role of pulmonology in BVVLS care, including clinical and functional monitoring, early initiation of NIV, and the implementation of airway clearance techniques.\n\nID: 40413968\nTitle: Clinical and electrophysiological characteristics and blood markers for short-term prognosis prediction in severe Guillain-Barr\u00e9 syndrome: a retrospective cohort study.\nAbstract: This study aimed to investigate the clinical, electrophysiological characteristics and blood inflammatory markers in severe Guillain-Barr\u00e9 syndrome (GBS) and their correlation with short-term prognosis. Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction. The nomogram model demonstrated an area under the ROC curve of 0.990, reflecting good potential clinical effect. The calibration curve showed good agreement between actual observations and nomogram predictions. The findings indicate that early assessment of the occurrence of bulbar palsy, mEGOS, IMN numbers, and NLR value can predict poor prognosis, with their combination providing improved accuracy for short-term prognosis in patients with severe GBS.\n\nID: 40364643\nTitle: Latest progress and challenges in drug development for degenerative motor neuron diseases.\nAbstract: Motor neuron diseases are sporadic or inherited fatal neurodegenerative conditions. They selectively affect the upper and/or lower motor neurons in the brain and spinal cord and feature a slow onset and a subacute course contingent upon the site of damage. The main types include amyotrophic lateral sclerosis, progressive muscular atrophy, primary lateral sclerosis, and progressive bulbar palsy, the pathological processes of which are largely identical, with the main disparity lying in the location of the lesions. Amyotrophic lateral sclerosis is the representative condition in this group of diseases, while other types are its variants. Hence, this article mainly focuses on the advancements and challenges in drug research for amyotrophic lateral sclerosis but also briefly addresses several other important degenerative motor neuron diseases. Although the precise pathogenesis remains elusive, recent advancements have shed light on various theories, including gene mutation, excitatory amino acid toxicity, autoimmunology, and neurotrophic factors. The US Food and Drug Administration has approved four drugs for use in delaying the progression of amyotrophic lateral sclerosis: riluzole, edaravone, AMX0035, and tofersen, with the latter being the most recent to receive approval. However, following several phase III trials that failed to yield favorable outcomes, AMX0035 has been voluntarily withdrawn from both the US and Canadian markets. This article presents a comprehensive summary of drug trials primarily completed between January 1, 2023, and June 30, 2024, based on data sourced from clinicaltrials.gov. Among these trials, five are currently in phase I, seventeen are in phase II, and eleven are undergoing phase III evaluation. Notably, 24 clinical trials are now investigating potential disease-modifying therapy drugs, accounting for the majority of the drugs included in this review. Some promising drugs being investigated in preclinical studies, such as ATH-1105, are included in our analysis, and another review in frontiers in gene therapy and immunotherapy has demonstrated their therapeutic potential for motor neuron diseases. This article was written to be an overview of research trends and treatment prospects related to motor neuron disease drugs, with the aim of highlighting the latest potentialities for clinical therapy.\n\nID: 40203549\nTitle: Clinical Characteristics and Prognostic Factors of Anti-GM1 Antibody-Positive Guillain-Barr\u00e9 Syndrome Spectrum Disorders in Children.\nAbstract: The study aimed to analyze the clinical features and risk factors for poor prognosis of Guillain-Barr\u00e9 syndrome (GBS) spectrum disorders in children positive for anti-tetrahexose monosialoganglioside (GM1) antibody. We collected data for children with anti-GM1 antibody-positive GBS spectrum disorders in Affiliated Children's Hospital of Chongqing Medical University between July 2018 and March 2024; 1:1 matching was performed for combined anti-ganglioside or anti-sulfatide antibody. The patients underwent comparative clinical characterization to determine the antibody phenotype-clinical phenotype and to analyze the possible risk factors for the poor prognosis of the disorders. Thirty-seven pediatric patients were recruited. Anti-GM1 antibody-positive GBS spectrum disorders were preceded by a prodromal event (25 of 37, 67.6%). The first symptom was mainly limb weakness (20 of 37, 54.1%), which could be predominately accompanied by autonomic nerve involvement (21 of 37, 56.8%). Seven features showed statistically significant differences (P\u00a0<\u00a00.05) between the positive group and the negative one, including cranial nerve involvement, bulbar palsy, low lower limb muscle strength at discharge, axonal type of electrophysiological typing, and clinical typing of acute motor axonal neuropathy. The GBS disability scores at discharge and at one month after discharge were higher than those in the control group. The shorter time to peak (<7.5\u00a0days) was identified as an independent risk factor for poor short-term prognosis of the disorders. Anti-GM1 antibody-positive GBS spectrum disorders have a relatively specific antibody phenotype-clinical phenotype. The shorter time to peak (<7.5\u00a0days) is an independent risk factor for poor short-term prognosis of the disorders in children.\n\nID: 40084652\nTitle: A Rare Guillain-Barr\u00e9 Syndrome Variant with Multi-Ganglioside Reactivity: A Case of Severe Cranial Nerve Involvement.\nAbstract: We present a rare case of acute immune-mediated polyradiculoneuritis, a Guillain-Barr\u00e9 Syndrome (GBS) variant, manifesting as ophthalmoparesis-ataxia, facial diplegia, and acute bulbar palsy, accompanied by a unique autoimmune profile. A 75-year-old female developed rapidly progressive symptoms, including bilateral non-reactive mydriasis, ptosis, complete ophthalmoplegia, bilateral facial weakness, tongue immobility, palatal paralysis, limb dysmetria, ataxia, and brisk generalized tendon reflexes, all while maintaining a preserved mental state. Symptoms emerged 10 days after a probable gastrointestinal infection. Severe bulbar dysfunction necessitated orotracheal intubation and a tracheotomy. Extensive cranial nerve involvement initially suggested a brainstem lesion, with oculomotor and acute bulbar palsy as prominent signs. However, brainstem and spinal magnetic resonance imaging along with cerebrospinal fluid analysis yielded negative results. Electromyography reveled a sensorimotor demyelinating polyradiculoneuropathy, and serum testing identified IgG antibodies targeting multiple gangliosides, including the disialosyl group and terminal NeuNAc(\u03b12-3)Gal. Treatment with intravenous immunoglobulin (IVIG) led to gradual clinical improvement. This case highlights a rare and severe GBS phenotype characterized by reactivity to multiple gangliosides. It highlights the role of shared ganglioside epitopes in antibody-mediated neurological damage and expands the clinical spectrum of GBS variants. Introducci\u00f3n: Presentamos un caso cl\u00ednico de polirradiculoneuritis aguda inmunomediada que inicialmente se manifest\u00f3 con oftalmoparesia-ataxia, diplegia facial y par\u00e1lisis bulbar aguda, acompa\u00f1ada de un perfil autoinmune caracter\u00edstico. Caso Cl\u00ednico: Describimos el caso de una mujer de 75 a\u00f1os con cl\u00ednica de progresi\u00f3n r\u00e1pida incluyendo midriasis bilateral no reactiva, ptosis, oftalmoplej\u00eda completa, paresia facial bilateral, paresia lingual, par\u00e1lisis del paladar, dismetr\u00eda en todas las extremidades, ataxia y reflejos osteotendinosos aumentados de forma generalizada, con nivel de conciencia preservado. La cl\u00ednica inici\u00f3 despu\u00e9s de una posible infecci\u00f3n gastrointestinal de aparici\u00f3n diez d\u00edas antes. Su estado cl\u00ednico empeor\u00f3 r\u00e1pidamente, requiriendo intubaci\u00f3n orotraqueal y traqueotom\u00eda debido a un compromiso bulbar severo. La afectaci\u00f3n concomitante de m\u00faltiples nervios craneales sugiri\u00f3 una lesi\u00f3n en el tronco encef\u00e1lico, destac\u00e1ndose la par\u00e1lisis oculomotora y bulbar aguda. La resonancia magn\u00e9tica del tronco encef\u00e1lico y m\u00e9dula espinal, junto con las pruebas de l\u00edquido cefalorraqu\u00eddeo, no mostraron alteraciones; la electromiograf\u00eda objetiv\u00f3 una polirradiculoneuropat\u00eda desmielinizante sensitivo-motora. La prueba de anticuerpos antigangli\u00f3sidos mostr\u00f3 positividad contra m\u00faltiples anticuerpos dirigidos al grupo dialosilo y al terminal NeuNAc(\u03b12-3)Gal.

Conclusiones: Nuestro caso ilustra la reactividad a m\u00faltiples gangli\u00f3sidos, destacando los ep\u00edtopos compartidos entre estas mol\u00e9culas y la capacidad de un \u00fanico anticuerpo para dirigirse a diversos tipos de gangli\u00f3sidos, subrayando adem\u00e1s un fenotipo extremadamente raro del s\u00edndrome de Guillain-Barr\u00e9.\n\nID: 40038221\nTitle: HIV associated motor neuron disease (MND): A case series with systematic review of literature.\nAbstract: Human immunodeficiency virus (HIV) associated motor neuron disease (MND) is very rare. HIV infection can cause an MND-like syndrome due to central nervous system (CNS) involvement de novo or during antiretroviral therapy (ART) due to CNS escape. We present two cases: one with a classic amyotrophic lateral sclerosis (ALS) phenotype, which was the manifestation of symptomatic CNS escape from ART, and the second with a primary lateral sclerosis (PLS) phenotype associated with underlying HIV infection. A systematic review of published literature of people living with HIV (PLHIV) who developed ALS/ MND was conducted using the PubMed, Embase, and Lilacs databases. A total of 91 cases were found, 89 of which were obtained from 37 articles, and two were included from our own case series. In patients with HIV-associated MND, 63 patients reviewed had a classic ALS phenotype followed by progressive muscular atrophy variant (12), progressive bulbar palsy (8), PLS (7) and bulbar onset ALS (1). Neuroimaging, electrophysiology, cerebrospinal fluid (CSF) analysis, CSF and serum HIV viral load, and CD4 count investigations were used for diagnosis. Following the initiation or modification of antiretroviral therapy (ART), approximately 70% exhibited an improvement or a stable disease course. HIV-associated MND is a rare condition that can occur in both ART-naive individuals and those on treatment. A proportion of cases (~\u200970%) show improvement with ART. Accurate diagnosis requires the exclusion of opportunistic infections, which remains a critical yet challenging aspect of managing this condition.\n\nID: 39995675\nTitle: Case report: A severe myositis mimicking bulbar palsy after administration of immune checkpoint inhibitors.\nAbstract: Immune Checkpoint Inhibitors (ICI) are nowadays a cornerstone of anti-cancer treatments. However, the wide spectrum of immune-related adverse events (irAEs) represents a challenge in the oncological practice. Our objective is to document rare complications of ICI to help the community of onco-immunologists. We reported the case of a severe myositis mimicking bulbar palsy treated in our Medical Oncology Department together with Internal Medicine Department. We present the clinical work-up (neurological exam, capillaroscopy) and the diagnostic tests (myositis specific and associated antibodies, nerve conduction study, electromyography) leading to this diagnosis. We also discussed the elimination of differential diagnoses (notably with normal MRI and cerebrospinal fluid analysis) and finally the clinical management of this severe irAE. A 57 years woman presented multiple sub-diaphragmatic adenopathies related with an advanced melanoma of unknown primary. She started a treatment with Ipilimumab (Ipi, anti CTLA-4) and Nivolumab (Nivo, anti PD-1) and presented at day 10 a grade IV myositis mimicking bulbar palsy with dysphonia, dysarthria and aphagia. In a multidisciplinary setting, she was treated with IV corticosteroids (methylprednisolone 1 mg/kg started at day 10, with a progressive decrease until 1 mg of prednisone in March 2024), IV immunoglobulins started at day 18 (1.5 g/kg in 2 days, administered monthly, with a progressive decrease and a cessation in June 2022), enteral nutrition, speech therapy and physical therapy, with noticeable improvement. After 4 years of follow-up, and only one infusion of Ipi/Nivo, the melanoma is still in complete response. We report an ICI-induced severe myositis mimicking bulbar palsy after the administration of Ipi/Nivo. The diagnosis and clinical care management of this rare complication requires a multi-disciplinary work-up.\n\nID: 39950622\nTitle: Bickerstaff brainstem encephalitis-Miller-Fisher syndrome (BBE-MFS) overlap with negative anti-GQ1b serology.\nAbstract: Bickerstaff brainstem encephalitis (BBE) and Miller-Fisher syndrome (MFS) are rare post-infectious neurological syndromes, usually involving 'anti-GQ1b ganglioside' antibodies. Both syndromes present with ophthalmoplegia and ataxia. However, BBE is differentiated by altered consciousness or pyramidal signs (central nervous system involvement), while MFS has areflexia (peripheral nervous system involvement). Here, we discuss a case of an elderly woman, who, after an initial episode of upper respiratory tract infection, developed bilateral ophthalmoplegia, facial and bulbar palsy, ataxia, depressed consciousness and areflexia. She was diagnosed clinically as a case of BBE-MFS overlap. However, serology was negative for anti-GQ1b antibodies, and brain imaging and cerebrospinal fluid (CSF) analysis were normal. Despite initial clinical deterioration and the need for intubation, she was treated successfully with intravenous immunoglobulin and eventually recovered. This case demonstrates that BBE and MFS can overlap and that early clinical diagnosis becomes essential even if anti-ganglioside antibodies, CSF and imaging studies are negative.\n\nID: 39880652\nTitle: [A case of L-2-hydroxyglutaric aciduria diagnosed with involuntary movements, in which improvement in motor symptoms was achieved following treatment].\nAbstract: A 49-year-old female presented with the primary complaint of hand tremors. Neurological examination on admission revealed signs of cognitive impairment, bulbar palsy, dystonia, cerebellar ataxia, and pyramidal tract disease. T2-weighted brain MRI revealed hyperintense signals in the subcortical white matter, basal ganglia, and cerebellar dentate nucleus, with no atrophy of the brainstem or corpus callosum. Urinary organic acid analysis revealed elevated 2-hydroxyglutaric acid levels. Although the optical isomers could not be distinguished, L-2-hydroxyglutaric aciduria was diagnosed based on the disease course, symptoms, and characteristic MRI findings. The patient was started on riboflavin-enriched compounds and levocarnitine, resulting in an improvement in the Scale for the Assessment and Rating of Ataxia (SARA) score from 21 to 15 after six months. The case suggests that symptoms in adult patients who have not been treated for a long time can be improved by appropriate diagnosis based on neurological presentation, characteristic MRI findings, and intervention.\n\nID: 39853526\nTitle: Clinical Diagnosis and Differential Diagnosis Between CSF1R- and AARS2-Related Leukoencephalopathy.\nAbstract: CSF1R-related leukoencephalopathy (CSF1R-L) and AARS2-related leukoencephalopathy (AARS2-L) were two disease entities sharing similar phenotype and even pathological changes. Although clinically, radiologically, and pathologically similar, they were caused by mutation of two different genes. As the rarity of the two diseases, the differential diagnosis of them was difficult. 23 CSF1R-L and 6 AARS2-L patients were enrolled from the Leukoencephalopathy Clinic, Peking Union Medical College Hospital in China. Detailed clinical information, neuroimaging manifestations, and genetic data were collected and analyzed. Demographically, female patients were more in AARS2-L than CSF1R-L. Clinically, cognitive impairment and emotion/personality change were common in both groups. Bulbar palsy, extrapyramidal symptoms, and hemiplegia/pyramidal impairment were more common in CSF1R-L, while ataxia was significantly more common in AARS2-L. Abnormal menstruation including infertility was significantly more in AARS2-L. Radiologically, similar features were found, including lateral ventricle-centered white matter lesions, involving corpus callosum, avoiding U fibers. The lesions showed persistent hyperintensity on DWI image and were not contrasted after gadolinium enhancement. In CSF1R-L, the lesions could be widespread confluent or patchy and spotted, extending to centrum semiovale and subcortical white matter occasionally, which was significantly different from AARS2-L. Besides, brain stem lesion caused by pyramidal degeneration, spotted or linear calcification and obviously brain atrophy were common in CSF1R-L. In AARS2-L, periventricular white matter rarefaction was significantly common. No genotype and phenotype association was found in these two diseases. Although similar, there were several clinical and radiological features helping differentiating the two distinct diseases.\n\nID: 39828328\nTitle: Long-term lung volume recruitment therapy maintains ventilator weaning in a patient with ALS following tracheostomy.\nAbstract: We report a case of amyotrophic lateral sclerosis (ALS) in a patient in their 50s, presenting with spastic paraparesis and bulbar palsy, treated with lung volume recruitment therapy (LVRT). From early stage in the disease, vital capacity (VC), lung insufflation capacity (LIC) and ALS Functional Rating Scale-Revised scores were regularly measured, and LVRT was continuously performed at home. After 10 years, the patient had complete limb function loss and required nutritional management via gastrostomy and full assistance with daily activities. Despite this, the gap between VC and LIC remained approximately 2000 mL, and the patient was not ventilator-dependent during the day after tracheostomy. Chest CT showed improvement in lower lobe atelectasis due to LVRT. Typically, respiratory physiotherapy is challenging in patients with bulbar palsy or post-tracheostomy, but in this case, LVRT successfully maintained lung mobility. Early LVRT implementation may improve ALS patients' survival prognosis and warrants further exploration.\n\nID: 42476408\nTitle: Overcoming Age Barriers: Endoscopic Endonasal Management of Pituitary Apoplexy in Elderly Patients - A Single Center Experience and Literature Review.\nAbstract: Pituitary apoplexy (PA) is an acute hemorrhagic event within the pituitary gland, most often occurring in pre-existing adenomas. In elderly patients, management is challenging due to frailty, comorbidities, and variable presentation. This study aimed to evaluate clinical features, management, and outcomes of PA in the elderly. We performed a retrospective analysis of elderly patients (\u226565 years) treated for PA at a tertiary referral center in Italy between 2011 and 2022. Data included demographics, clinical presentation, endocrine status, tumor characteristics, frailty (mFI-5), management, and outcomes. Twenty-eight patients (median age 71 years; 79% male) were included. Visual disturbances occurred in 61%, cranial nerve palsy in 71%, and hypopituitarism in 43%. Median mFI-5 was 1. Steroids were administered in 61% of cases. At follow-up, pituitary function did not recover in patients with preoperative hypopituitarism and worsened in 11%, with 10% developing panhypopituitarism. Postoperative hypothyroidism occurred in 54%. Higher frailty showed a non-significant trend toward worse cranial nerve and endocrine outcomes. Steroid therapy was significantly associated with visual improvement (OR 47.1, p = 0.04). PA in the elderly shows heterogeneous presentation and significant endocrine morbidity. Early diagnosis and prompt steroid therapy are crucial. The endoscopic endonasal approach is safe and effective, but careful patient selection remains essential.\n\nID: 42437610\nTitle: Vestibular syndrome associated with subcutaneous hemangiosarcoma in a cat.\nAbstract: Hemangiosarcomas (HSAs) are rare neoplasms in cats, with cutaneous and subcutaneous forms occurring more frequently than visceral HSAs and often associated with chronic ultraviolet radiation exposure. Herein, we report a case of vestibular syndrome secondary to subcutaneous hemangiosarcoma in a 2-year-old cat. The patient was presented with ataxia, proprioceptive deficits, cranial nerve palsy, mild nystagmus, and head tilt. The cat tested positive for feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV), while complete blood count, serum biochemical profile, and albumin-to-globulin ratio were within normal limits. Based on the neurological findings and the absence of systemic abnormalities, central vestibulopathy was suspected. Corticosteroid therapy resulted in transient clinical improvement within 36 hours; however, 48 hours later, the cat developed vocalization and reduced consciousness. Due to the poor prognosis, euthanasia was elected. Necropsy revealed two dark-red subcutaneous nodules (\u223c1 cm) in the right thoracic region, multifocal omental nodules, and a red mass (3.2 \u00d7 2.7 \u00d7 1.3 cm) compressing and replacing part of the cerebellar parenchyma. Histopathologically, all nodules consisted of proliferating neoplastic endothelial cells forming irregular vascular channels filled with erythrocytes, consistent with hemangiosarcoma. Cerebellar metastasis accounted for the clinical signs of central vestibulopathy. Although meningoencephalitis is the most common cause of central vestibular disease in cats, neoplasms involving the cerebellum or brainstem should also be considered as differential diagnoses.\n\nID: 42382313\nTitle: Diagnostic Value of Pupil Involvement and Yield of Vascular Imaging in Isolated Third Cranial Nerve Palsy: A 10-Year Retrospective Study.\nAbstract: Isolated third cranial nerve palsy may result from presumed microvascular ischemia or clinically significant structural lesions. The reliability of pupil involvement for distinguishing non-microvascular causes remains uncertain. To describe the etiologic spectrum of isolated third cranial nerve palsy and evaluate the diagnostic performance of pupil involvement and the yield of neuroimaging. This retrospective observational study reviewed adult patients with isolated third cranial nerve palsy at Mukdahan Hospital, Thailand, between January 2015 and August 2025. Patients with traumatic, postoperative, recurrent, multiple cranial nerve palsies, or incomplete records were excluded. Clinical features, neuroimaging findings, etiologies, and outcomes were analyzed. Of 61 records assessed, 51 patients were included. Mean age was 62.3 \u00b1 8.7 years, and 26 patients (51.0%) were male. Presumed microvascular ischemia was the most common etiology (42/51, 82.4%). Non-microvascular causes were identified in 9 patients (17.6%), including aneurysm in 6, nasopharyngeal carcinoma in 1, cavernous sinus meningioma in 1, and invasive aspergillosis in 1. Pupil involvement was more frequent in the non-microvascular group than in the presumed microvascular group (66.7% vs 23.8%, p = 0.020). Sensitivity, specificity, positive predictive value, and negative predictive value were 66.7%, 76.2%, 37.5%, and 91.4%, respectively. In multivariable analysis, pupil involvement remained independently associated with non-microvascular etiology (adjusted OR 8.00, 95% CI 1.49-42.85, p = 0.015). The diagnostic yield of neuroimaging was 18.8% overall and 25.0% among patients undergoing vascular imaging. Pupil involvement was associated with non-microvascular etiology but had only moderate diagnostic performance; pupil sparing did not reliably exclude clinically significant lesions. These findings suggest that vascular imaging may be clinically informative when structural causes cannot be confidently excluded, particularly given that all non-microvascular cases in this cohort were identified through vascular imaging.\n\nID: 42311863\nTitle: Clinical characteristics of hypoglossal nerve palsy secondary to internal carotid artery dissection: a systematic review and illustrative case.\nAbstract: Hypoglossal nerve palsy (HNP) secondary to extracranial internal carotid artery dissection (ICAD) is a rare but clinically important condition that may be overlooked, particularly in the absence of ischemic lesions on brain imaging. We aimed to systematically characterize its clinical features, diagnostic patterns, treatment strategies, and outcomes. A systematic review was conducted in accordance with PRISMA 2020 guidelines and registered in PROSPERO (CRD420251141162). PubMed, Scopus, Web of Science, and Embase were searched without language or date restrictions. Studies reporting adult patients with HNP attributable to ICAD were included. Clinical data, imaging findings, treatment modalities, and outcomes were extracted and analyzed descriptively and exploratorily. A total of 73 studies comprising 87 patients were included. The mean age was 48.5\u202fyears, and 86.2% were male. Isolated HNP was observed in 64.3% of cases, and diagnostic error occurred in 31.0%, frequently leading to delayed management. Most patients were managed medically (89.7%), and overall favorable outcomes were achieved in 65.6% of patients. Surgical or endovascular treatment was performed in a minority of cases (10.3%). The presence of pseudoaneurysm was significantly associated with increased likelihood of surgical or endovascular treatment (p\u202f=\u202f0.007) and shorter follow-up duration (p\u202f=\u202f0.015), although overall outcomes did not differ between groups. Extracranial ICAD presenting as HNP is an uncommon but clinically important condition with a substantial risk of diagnostic delay. Early vascular imaging should be considered in patients with isolated or atypical hypoglossal nerve palsy, even in the absence of ischemic lesions on brain MRI. Most patients achieve favorable outcomes with medical therapy; however, selected patients-particularly those with pseudoaneurysm or persistent or progressive symptoms-may require surgical or endovascular intervention. Further large-scale studies are needed to refine patient selection and optimize management strategies. https://www.crd.york.ac.uk/PROSPERO/view/CRD420251141162, identifier (CRD420251141162).\n\nID: 42289571\nTitle: Multilevel surgical management for severe dysphagia due to lower cranial nerve palsy with multimodal functional assessment: a case report.\nAbstract: Lower cranial nerve (LCN) palsy may develop following tumor resection in the cerebellopontine angle or jugular foramen, often resulting in dysphagia and dysphonia. Although many patients recover with rehabilitation, some exhibit persistent functional deficits. In such cases, detailed pathophysiologic evaluation may assist in guiding surgical intervention to improve outcomes. A 77-year-old woman presented with severe dysphagia and hoarseness after resection of a right cerebellopontine angle meningioma, which caused glossopharyngeal, vagus, and accessory nerve palsies. Despite initial recovery, she developed repeated aspiration pneumonia and malnutrition. Comprehensive reassessment using high-resolution manometry (HRM) and dynamic swallowing computed tomography (CT) revealed right-sided velopharyngeal insufficiency, pharyngeal constrictor dysfunction, vocal fold paralysis with paramedian fixation, and impaired upper esophageal sphincter relaxation. A tailored multi-procedural surgical approach was performed, including right pharyngeal flap, arytenoid adduction, right hypopharyngeal pharyngoplasty with expanded polytetrafluoroethylene mesh reinforcement, right cricopharyngeal myotomy, and tracheostomy. Postoperatively, swallowing and phonation significantly improved. The patient resumed oral intake, and tracheostoma closure was performed on postoperative day (POD) 25. Maximum phonation time improved sevenfold by POD 32. She was discharged on POD 33, and resumed a regular diet with some limitations by 3 months postoperatively. Intractable dysphagia due to complex LCN dysfunction requires individualized surgical strategies. Multimodal functional assessment, including dynamic swallowing CT and HRM, aids precise evaluation and helps refine surgical planning in selected complex cases, potentially leading to significant improvements in quality of life.\n\nID: 42269965\nTitle: Anterior segment OCT, Schlemm's canal, and carotid-cavernous fistula: Reflections on a clinical case.\nAbstract: We rerport a 69-year-old man who presented with diplopia. He had a conjunctival injection with corkscrew-vessels, proptosis, and sixth cranial nerve palsy in his right eye (RE), and was diagnosed with a right carotid-cavernous fistula (CCF). Intraocular pressure was within normal limits. Gonioscopic examination revealed a pinkish appearance of the trabecular meshwork, but the Schlemm's canal could not be identified on anterior segment optical coherence tomography (OCT). We discuss the potential usefulness and limitations of OCT in the assessment of the Schlemm's canal in CCF.\n\nID: 42254312\nTitle: Partial pupil-sparing third nerve palsy as a manifestation of cerebral toxoplasmosis in an HIV-positive patient: A case report.\nAbstract: Neuro-ophthalmic manifestations are common in patients with advanced human immunodeficiency virus (HIV) infection and may result from opportunistic intracranial infections. However, partial pupil-sparing third cranial nerve palsy is an uncommon presentation in this population and may be misleading, as it is often presumed to be ischemic. We report an atypical presentation of cerebral toxoplasmosis manifesting as partial pupil-sparing third nerve palsy. We report the case of a 37-year-old HIV-positive male with advanced human immunodeficiency virus infection who presented with headache, seizures, and binocular diplopia and was found to have a partial pupil-sparing third nerve palsy. Neuroimaging revealed multiple intracranial enhancing lesions with surrounding vasogenic edema. Cerebrospinal fluid analysis demonstrated varicella zoster virus positivity, and stereotactic brain biopsy ultimately confirmed cerebral toxoplasmosis. The patient was managed with antimicrobial therapy and showed clinical improvement. In patients with human immunodeficiency virus infection, pupil-sparing third nerve palsy should not be presumed to be exclusively ischemic, as infectious and other opportunistic etiologies may underlie its presentation. Careful clinical assessment, detailed examination, and appropriate neuroimaging are essential for accurate diagnosis and timely management.\n\nID: 42227005\nTitle: Real-World Incidence and Management of Non-Immune Effector Cell-Associated Neurotoxicity Syndrome Neurologic Events Following Ciltacabtagene Autoleucel in Multiple Myeloma.\nAbstract: Ciltacabtagene autoleucel (cilta-cel) is a chimeric antigen receptor T-cell (CAR-T) therapy for relapsed/refractory multiple myeloma (RRMM) approved after 1 prior line of therapy (LOT). Non-immune effector cell-associated neurotoxicity syndrome (ICANS) neurologic events (NEs) may occur following infusion. This real-world study evaluated non-ICANS NE onset and management among patients with RRMM treated with cilta-cel. Electronic medical records from Loopback Analytics (02/2022-05/2025) were used, supplemented with physician notes. Adults treated with cilta-cel after 1-3 and \u22654 prior LOT were included (N=171). New-onset non-ICANS NEs included cranial nerve palsy (CNP), parkinsonism, and Guillain-Barr\u00e9 syndrome. Clinical outcomes among these patients were described. Among 171 patients, 73\u00a0had 1-3 prior LOT and 98\u00a0had \u22654 prior LOT. Among patients with 1-3 prior LOT (median follow-up: 6.1 months), CNP occurred in 4 patients, while no parkinsonism or Guillain-Barr\u00e9 syndrome were observed. Following CNP onset, symptoms improved among 3 patients. Among patients with \u22654 prior LOT (median follow-up: 17.4 months), CNP occurred in 3 patients, while parkinsonism and Guillain-Barr\u00e9 syndrome each occurred in 1 patient. All patients with CNP had symptom improvement and the patient with Guillain-Barr\u00e9 syndrome had symptom resolution. Median peak ALC (103 cells/\u00b5L) was higher in patients with versus without non-ICANS NEs (1-3 prior LOT: 7.60 vs 2.12; \u22654 prior LOT: 11.64 vs 1.96). All patients with events had at least a partial response to cilta-cel and remained alive at the end of follow-up. This real-world cohort showed low incidence of CNP, parkinsonism, and Guillain-Barr\u00e9 syndrome following cilta-cel. Elevated post-infusion ALC warrants further investigation into its role as a biomarker to inform monitoring and management strategies, consistent with prior reports. Most patients with CNP reported improvement, the patient with Guillain-Barr\u00e9 syndrome reported resolution, all patients with available response assessments responded to cilta-cel, and no deaths were reported.\n\nID: 42219397\nTitle: A systematic review of extraocular movement-related schwannomas (CN III, IV, VI). Part II: Surgical outcomes and prognostic factors for postoperative nerve function.\nAbstract: Extraocular movement-related schwannomas (EOMS)-arising from the oculomotor (CN III), trochlear (CN IV), or abducens (CN VI) nerves-are rare, and comparative data on nerve-specific surgical outcomes and prognostic factors are limited. This paper represents Part II of a two-part study on EOMSs. While Part I addressed tumor localization, clinical features, and surgical approaches, the present paper focuses on surgical outcomes and prognostic factors for postoperative neurological function. Systematic review identified surgically treated EOMS. Of 156 patients found, 117 had complete pre-/postoperative data; with the three institutional cases, 120 patients were analyzed. Variables extracted were tumor size, extent of resection (EOR), cavernous sinus involvement (CSI), and postoperative function of the nerve of origin. Univariate and multivariable logistic regression identified predictors of persistent postoperative origin nerve-related deficits. The cohort comprised 52 CN III (43.3%), 34 CN IV (28.3%), and 34 CN VI (28.3%) tumors. Mean diameter was 30.1 mm. CSI occurred in 43.3% (more frequent in CN III and CN VI). Gross-total resection (GTR) was achieved in 69.2% overall and more often in CN IV (94.1%). Preoperative nerve deficits were present in 73.3%; among these, postoperative improvement occurred in 31.8%. New postoperative palsy developed in 40.6% of patients without preoperative palsy. At final follow-up, persistent nerve-of-origin deficits were present in 60.0%. On multivariable analysis, tumor diameter\u2009\u2265\u200935 mm (OR 2.47, 95% CI 1.06-5.73; p\u2009=\u20090.0354), CSI (OR 2.56, 95% CI 1.05-6.27; p\u2009=\u20090.039), and trochlear origin versus abducens (OR 3.24, 95% CI 1.03-10.1; p\u2009=\u20090.0438) were independently associated with persistent origin nerve-related deficits. Persistent nerve-of-origin deficits are common after EOMS surgery. Larger tumors (\u2265\u200935 mm), CSI, and trochlear origin confer higher risk, whereas EOR does not independently determine functional outcome. For high-risk subsets, a function-preserving strategy may better balance tumor control and neurological function.\n\nID: 42186491\nTitle: Collet-Sicard syndrome resulting from a Skull Base Paraganglioma: a case report.\nAbstract: Collet-Sicard syndrome is a rare neurological condition resulting from lesions at the jugular foramen and hypoglossal canal, leading to combined palsy of cranial nerves IX, X, XI, and XII. Neoplastic causes are most commonly involved, while benign tumors such as paragangliomas are infrequent etiologies. We report a 58-year-old woman who presented with progressive dysphagia and unilateral lower cranial nerve dysfunction. Clinical examination demonstrated right-sided palsy of cranial nerves IX, X, XI, and XII. Magnetic resonance imaging revealed a lobulated, avidly enhancing lesion centered in the right hypoglossal canal with extension into the jugular foramen and adjacent carotid space, radiologically suggestive of a skull base paraganglioma. Based on the characteristic clinical and radiological findings, a diagnosis of Collet-Sicard syndrome secondary to a skull-base paraganglioma was made. This case underscores the importance of through neurological examination and early targeted imaging in patients presenting with progressive dysphagia and unilateral lower cranial nerve palsies.\n\nID: 42161729\nTitle: Non-ICANS Neurologic Events in Patients With Relapsed/Refractory Multiple Myeloma Treated With Ciltacabtagene Autoleucel: Clinical Presentation and Management in CARTITUDE Studies.\nAbstract: B-cell maturation antigen-targeting chimeric antigen receptor (CAR) T-cell therapies have demonstrated remarkable efficacy in relapsed/refractory multiple myeloma (RRMM). However, emerging non-immune effector cell-associated neurotoxicity syndrome (non-ICANS) neurologic events-including cranial nerve palsy (CNP) and immune effector cell (IEC)-parkinsonism (also called movement and neurocognitive toxicity)-warrant vigilance. This review summarizes clinical findings from the CARTITUDE trials, which evaluated ciltacabtagene autoleucel in > 300 patients with RRMM. CNP occurred in 6.3% of patients, with a lower incidence in more heavily pretreated patients (\u2265 3 prior lines of treatment [pLOT]: 3% vs. 1-3 pLOT: 9%). Median CNP onset was day 22 postinfusion; most cases were low grade, and 90% recovered completely. IEC-parkinsonism involves motor, cognitive, and personality changes; lower incidence was observed in less heavily pretreated patients (1% vs. 6%). Median time to onset was 56 days postinfusion; however, with greater awareness, IEC-parkinsonism may be recognized earlier. Emerging data suggest that early, aggressive intervention may result in better outcomes. High CAR-T cell expansion is associated with increased risk of CNP and IEC-parkinsonism. In the early postinfusion period (days 10-28), absolute lymphocyte count (ALC) strongly correlates with circulating CAR-T cell levels and could help identify patients at increased risk of neurologic events. Prophylactic interventions, including a short course of steroids, triggered by elevated ALC before symptom onset, are under investigation. Education of patients, caregivers (including family), local oncologists, and neurologists seeing patients outside CAR-T infusion centers is essential to facilitate timely recognition, referral to the CAR-T center, and management.\n\nID: 42142527\nTitle: Rare adverse events after COVID-19 vaccination among Swedish older adults-evidence from a nationwide register-based study.\nAbstract: COVID-19 vaccinations have saved millions of lives, particularly among older adults. Rare potential adverse events have been reported in case reports, but risks among older adults remain unclear. This study assessed risks of selected potential adverse events in this population. We included more than 2 million Swedish adults \u226565y in a nationwide register-based cohort. Post-vaccination risks were assessed for herpes zoster (HZ), encephalitis, myelitis and encephalomyelitis, multiple sclerosis (MS), myasthenia gravis, cranial nerve palsy, sudden sensorineural hearing loss (SSNHL), postinfectious arthritis and polymyalgia rheumatica (PMR) in several risk windows (1-30, 31-60, and 61-180\u00a0days) after each vaccine dose. Hazard ratios (HRs) with 95% confidence intervals (95%CIs) compared with unvaccinated were estimated by Cox regression adjusted for potential confounders. Sensitivity analyses included adding primary health care (PHC) visits, and applying analysis-specific 5-year disease-free wash-out periods. No increased HRs were observed for most outcomes. SSNHL showed increased HRs within 180\u00a0days after each dose [1.60 (95%CI 1.15-2.24); 1.43 (1.03-1.99); 1.61 (1.05-2.46) for dose 1, 2 and 3], with similar estimates across all three risk windows. Increased HRs were also seen for PMR after dose 2 [1.14 (1.04-1.24)] and dose 3 [1.16 (1.03-1.30)], with higher HRs during later time windows. HZ showed increased HRs in the sensitivity analysis with PHC visits, [1.19 (1.07-1.31); 1.31 (1.19-1.43); 1.42 (1.26-1.60) for dose 1, 2 and 3]. MS showed reduced risk after dose 3 in the sensitivity analysis with longer wash-out (targeting incident MS), but not in the main analysis (potential relapses included). COVID-19 vaccines are generally safe in older adults, with very low incidence of the potential rare adverse events assessed. Slightly increased relative risks for SSNHL, PMR and HZ were observed, but these findings do not alter the overall benefit-risk profile of COVID-19 vaccination in older adults.\n\nID: 42137716\nTitle: Clinico-Radiological Presentation and Management of Carotid-Cavernous Fistulae: Real-Time Institutional Experience From Pakistan.\nAbstract: Carotid-cavernous fistula (CCF) is an abnormal communication between the carotid artery and the cavernous sinus. This communication can be either high-flow or low-flow. Depending on the distinct anatomy of the shunt, it has effects on the various neurovascular structures that lie within the cavernous sinus. To evaluate the immediate\u00a0outcomes of CCF patients undergoing surgical and endovascular management. This is a retrospective observational study conducted at\u00a0the Departments of Neuroendovascular Surgery and Neurosurgery at Punjab Institute of Neurosciences, Lahore. Consecutive patients diagnosed with CCF, who underwent diagnostic evaluation or treatment at the institution between\u00a0January 2023 and December 2025, were included.\u00a0Descriptive statistics were applied to analyze characteristics and outcomes. Of the total 10\u00a0patients, the most common clinical presentation was proptosis (90%; n=9), followed by chemosis (40%; n=4), ophthalmoplegia (30%; n=3), and cranial nerve palsy (10%; n=1). The majority of these cases were high flow (80%; n=8), categorized as being Barrow A. Arterial feeders originated exclusively from the internal carotid artery (ICA) in 60% (n=6) of cases, while 10% (n=1) were from the external carotid artery (ECA). Anterior and posterior drainage of CCF was mediated by the superior ophthalmic veins (SOV) (40%; n=4) and inferior petrosal veins (IPV) (20%; n=2), respectively. The majority of patients in our case series underwent stent (PK Papyrus, Biotronik SE & Co. KG, Berlin, Germany)\u00a0placement, i.e., 70% (n=7), followed by ICA ligation in 20% of cases (n=2). Postoperative imaging revealed a fistulous leak in 60% (n=6), complete obliteration in 10%, and mild flow in 1% (n=1). Clinical outcomes improved in 90% (n=9), and no post-procedural hemorrhage, infarction, or cranial nerve deficit was reported. Most of the patients had neuro-ophthalmic manifestations. Direct-type CCFs were the common type\u00a0in our small case series,\u00a0affecting the male gender predominantly, and most cases were post-traumatic. The endovascular management of CCF using covered stent deployment (PK Papyrus) yields reasonable radiological obliteration of the fistula, improved visual outcomes, and minimal intraoperative and immediate postoperative complications.\n\nID: 42133956\nTitle: Adult Idiopathic Intracranial Hypertension Without Papilledema: Systematic Review of Literature and Future Perspectives.\nAbstract: Idiopathic intracranial hypertension without papilledema (IIHWOP) remains poorly understood. This review summarizes the diagnostic challenges and potential management of adults with IIHWOP. A detailed search of the scientific literature, combining MeSH and free-text terms, included all English-language papers on PubMed, from inception to June 8, 2025. In this review, we used the term IIHWOP to describe patients without evidence of active or previous papilledema. The diagnosis of IIHWOP is based on elevated lumbar puncture opening pressure accompanied by either sixth cranial nerve palsy or neuroimaging features of intracranial hypertension, which may lack specificity. Clinical presentation frequently mimics primary headache disorders, and lumbar puncture remains an invasive procedure without clear management implications in IIHWOP, as there are no high-quality studies evaluating medical or surgical therapies. Recommendations for investigation and clinical care remain largely inferred from idiopathic intracranial hypertension. Given the absence of evidence for risk of vision loss, invasive procedures should be avoided, and management should focus on weight loss and optimized headache management.\n\nID: 42131169\nTitle: Relapsed Extranodal NK/T-Cell Lymphoma Presenting as Unilateral Third Cranial Nerve Palsy: A Rare Case Report.\nAbstract: Extranodal natural killer/T-cell lymphoma (ENKTL) is a rare and aggressive form of non-Hodgkin lymphoma. It most commonly affects the nasal cavity and sinuses. While only few of cases of third cranial nerve palsy have been reported in association with diffuse large B-cell lymphoma and Burkitt lymphoma, its occurrence as a presenting feature of ENKTL is exceptionally rare. Here, we present a patient with isolated third cranial nerve palsy as the initial manifestation of relapsed ENKTL. A 67-year-old woman with a history of ENKTL in remission was admitted with bilateral periorbital swelling, nasal purulent discharge, and congestion following nasal reconstruction. She was diagnosed with preseptal cellulitis and sinusitis and subsequently treated with IV antibiotics. She later developed a right third nerve palsy with pupillary involvement. A CT angiogram ruled out an aneurysm, however brain MRI showed perineural spread affecting the cavernous sinus. Further cranial nerve involvement prompted a biopsy of the sinus, confirming ENKTL. A PET scan was done. No uptake in the brain, sinuses, or the rest of the body was observed. A bone marrow biopsy was subsequently performed revealing marrow involvement with ENKTL, suggesting metastatic spread beyond the sinuses. Unfortunately, the patient developed sepsis and subsequently passed away. This case emphasizes the importance of early consideration of malignancy who present with atypical neurological symptoms. Given the risk of false-negative imaging results, a multimodal approach is essential. This should include high-resolution MRI coupled with neuroradiological review, biopsy with histopathological analysis when feasible, FDG PET scan and lumbar puncture with CSF analysis.\n\nID: 42082308\nTitle: Efficacy and Tolerance of Cladribine for Non-Langerhans Cell Histiocytosis.\nAbstract: Erdheim-Chester Disease (ECD) and Rosai-Dorfman Disease (RDD) Are Rare Non-Langerhans Cell Histiocytoses That Share Several Clinical and Histological Features, Including the Accumulation of CD1a- Histiocytes in Organs. Cladribine, a Purine Analog, Leads to an Overall Response Rate (ORR) of 91% in Langerhans-Cell Histiocytoses. Whether the Same Results Could Be Obtained in Non-Langerhans Cell Histiocytoses Remains To Be Determined. We retrospectively assessed the efficacy of cladribine according to clinical and radiological responses in consecutive patients with a diagnosis of ECD, RDD, or non-classified non-Langerhans cell histiocytosis. Twenty-One Patients Were Included in This Study (17 Males, Median Age at Cladribine Treatment 53\u2009Years). The Clinical ORR Was 62% (44% in ECD, 70% in RDD), whereas the Radiological ORR Was 43% (44% in ECD, 30% in RDD). Four of Five Patients With Cranial Nerve Palsy Responded Clinically (80%), whereas Pseudo-Degenerative CNS Involvement Did Not Improve (n\u2009=\u20093). Six Patients With Multisystemic Involvement Did Not Require Additional Treatment After Achieving a Radiological Response (n\u2009=\u20094) or After Achieving Radiological Stable Disease (n\u2009=\u20092), with a Median Follow-Up of 2.3\u2009Years (Range 0.5-9.5). After They Achieved a Radiological Response, 4/9 (44%) Patients Relapsed in a Median Time of 18\u2009Months (Range 6-95). The Safety Profile Showed That 19/19 Patients Experienced Lymphopenia, Whereas Only 2/19 Had Clinical Infectious Events (9%). These Results Provide New Evidence of the Efficacy of Cladribine in Non-Langerhans Cell Histiocytosis and Brings New Data on the Safety Profile of This Drug in Histiocytoses.\n\nID: 42065796\nTitle: X-linked hypophosphatemia and spinal cord compression: a systematic review and illustrative case.\nAbstract: Systematic review. X-linked hypophosphatemia (XLH) is a rare genetic disorder characterized by impaired phosphate homeostasis due to renal phosphate wasting. It leads to osteomalacia and skeletal abnormalities and represents the most common inherited cause of vitamin D-resistant rickets. In some patients, heterotopic ossification of the ligamentum flavum and paravertebral ligaments may result in spinal cord compression and myelopathy. Due to its rarity, large case series evaluating patient characteristics and surgical outcomes are lacking. We conducted a PRISMA-P based systematic review on spine surgery and X-linked hypophosphatemia from 1960 to 2022. Twenty-five studies were included, comprising 32 clinical cases. An illustrative case is also presented. Thirty-two patients (16 females and 16 males) with spinal cord compression due to XLH were included in this systematic review. Thirty out of 32 patients underwent surgery (one death and one refusal of surgery). The mean age of onset of symptoms was 41\u00a0years. 83% (25/30) had reduction of their symptoms after surgery, and 57% (17/30) had full recovery post-operatively. The mean follow-up time was 42\u00a0months. The recurrence rate was 13% (4/32). One case of suboccipital decompression was complicated by cranial nerve palsy. Patients with XLH requiring surgery appear to have good functional outcomes and low complication rates. However, recurrence is not uncommon, supporting the need for long-term follow-up.\n\nID: 42050282\nTitle: Pituitary stalk biopsy - A systematic review of the safety and efficacy of stalk lesion biopsy.\nAbstract: INTRODUCTION: A myriad of pathological process may involve the pituitary stalk (infundibulum), and despite extensive investigations, biopsy is often required. Due to the rarity of the procedure, the risks and yield of stalk biopsy are not well known, with important implications for clinical decision making. METHODS: A systematic review was performed in accordance with the PRISMA statement. Studies that reported diagnostic yield and complication rates after stalk biopsy were included. Bias was assessed using ROBINS-V2. RESULTS: A total of 13 studies, including 832 patients and 406 biopsies were included. Mean time from diagnosis to biopsy was 11 months. Preoperative visual symptoms were seen in 29.1%, AVP-deficiency (diabetes insipidus) in 71.0%, and hypopituitarism in 66.3%. Biopsy was predominately performed through the endoscopic transsphenoidal approach (70.9%). Diagnostic yield was 95.8%, and complications included postoperative CSF leak (1.6%), visual worsening (1.6%), new cranial nerve palsy (1.2%), new permanent AVP-deficiency (9.0%), new hypopituitarism (15.7%), and meningitis (2.7%). CONCLUSION: Pituitary stalk biopsy is a high yield and safe diagnostic test, with low periprocedural morbidity. The rate of new endocrinopathy compares favourably to the natural history of progressive stalk disease. Stalk biopsy could be considered earlier in the workup of undifferentiated progressive or symptomatic stalk lesions to avoid unnecessary delays in diagnosis and treatment.\n\nID: 42032505\nTitle: Posterior fossa hematoma: CT perfusion as a tool to reveal occult intracranial hypertension and support surgical decision-making - a case report.\nAbstract: BACKGROUND: Spontaneous posterior fossa hematoma is a neurological emergency associated with rapid deterioration from brainstem compression and localized intracranial hypertension. The resulting mass effect can reduce regional perfusion, but these changes are often not fully appreciable on non-contrast CT, and MRI is not always feasible in unstable patients. Invasive intracranial pressure (ICP) monitoring in the posterior fossa could provide direct information on compartmental pressure; however, catheter placement is technically challenging and carries risks including cerebellar hemorrhage, cerebrospinal fluid (CSF) leak, cranial nerve palsy, and brainstem contusion. Consequently, infratentorial ICP monitoring is rarely used, and treatment decisions are based on clinical examination, supratentorial ICP values, and conventional imaging, which may underestimate pressure effects. CT perfusion (CTP) offers a rapid, noninvasive method to assess regional perfusion, detect indirect signatures of occult intracranial hypertension, and identify cerebellar tissue at risk of reversible ischemia. CASE PRESENTATION: A 50-year-old woman with arterial hypertension was found comatose with a Glasgow Coma Scale (GCS) score of 3, mid-mydriatic non-reactive pupils, and absent airway protective reflexes. Non-contrast CT revealed a large right cerebellar hematoma. CT perfusion demonstrated hypoperfusion at the hematoma site, with prolonged time-to-maximum (TMAX) in the surrounding cerebellar parenchyma and reduced cerebral blood flow (CBF) despite preserved cerebral blood volume (CBV), suggesting salvageable tissue. In the absence of large-vessel stenosis, prolonged TMAX was interpreted as most consistent with reduced effective cerebral perfusion pressure, plausibly related to compartmental intracranial hypertension in the posterior fossa. Prolonged TMAX with low CBV was also observed in the ipsilateral cerebral peduncle, indicating localized ischemia likely related to upward transtentorial herniation. The patient underwent emergency external ventricular drain placement and posterior fossa decompression with hematoma evacuation. Follow-up CTP on postoperative day seven showed normalization of perfusion parameters, with improved CBV and CBF and reduced TMAX. CONCLUSIONS: This case illustrates how CTP can complement conventional imaging in posterior fossa hematomas by providing physiological information that is otherwise difficult to obtain invasively. By revealing perfusion patterns consistent with occult compartmental intracranial hypertension and demonstrating viable tissue at risk, CTP may counterbalance prognostic nihilism and support timely surgical decision-making in patients with posterior fossa hematoma.\n\nID: 42002689\nTitle: Early diagnostic prediction model for inflammatory and ischemic ocular motor cranial nerve palsy.\nAbstract: OBJECTIVE: To develop an early diagnostic prediction model to differentiate cavernous sinus inflammation (inflammation group) from microvascular ischemic ocular motor cranial nerve (CN) palsy (ischemic group) at early presentation. METHODS: A total of 66 and 117 patients within 2 weeks of symptom onset were enrolled in the inflammation and ischemic groups. Twenty-two potential predictors were evaluated; predictors that remained significant after Benjamini-Hochberg adjustment (false discovery rate 0.05) were entered into a multivariable logistic regression model. Discrimination was assessed by the area under the receiver operating characteristic curve (AUC), and calibration by the Hosmer -Lemeshow goodness-of-fit test. RESULTS: Significant predictors included vascular risk factor scores (VRFs), ocular motor nerve palsy scale (OMNPS) score, aggregate index of systemic inflammation (AISI), history of diabetes, and cavernous sinus thickness. The AUC was 0.899 (95% confidence interval, 0.838 to 0.939). At the optimal probability cutoff(0.674), sensitivity and specificity were 72.3% and 89.7%, respectively. The Hosmer-Lemeshow test yielded \u03c72\u2009=\u20094.262, P\u2009=\u20090.833. CONCLUSIONS: The logistic regression\u2013based model showed good discrimination and calibration for differentiating cavernous sinus inflammation from microvascular ischemic ocular motor CN palsy during early presentation, and may assist early clinical decision-making.\n\nID: 42000954\nTitle: Real-World Description of Non-ICANS Neurologic Events Among Patients with Relapsed or Refractory Multiple Myeloma Treated with Ciltacabtagene Autoleucel Using Two Large US Databases.\nAbstract: Ciltacabtagene autoleucel (cilta-cel) is a B-cell maturation antigen-directed chimeric antigen receptor T-cell therapy approved in the USA for relapsed or refractory multiple myeloma (RRMM) as early as following first relapse, based on pivotal CARTITUDE-1 (\u2265 4 prior lines of therapy [LOT]) and CARTITUDE-4 (1-3 prior LOT) trials, which reported high response rates and prolonged survival. In CARTITUDE-1 and CARTITUDE-4, rates of all-grade parkinsonism were 6% and\u2009<\u20091%, respectively, while rates of cranial nerve palsy were 3% and 9%, respectively. This study aimed to characterize new-onset nonimmune effector cell-associated neurotoxicity syndrome (non-ICANS) neurologic events (NEs) among patients with RRMM receiving cilta-cel after 1-3 or\u2009\u2265 4 prior LOT. This retrospective study used two real-world data sources: open and closed insurance claims from the Komodo Research Database (February 2021-November 2024), and electronic medical records from Loopback Analytics (February 2021-December 2024). New-onset non-ICANS NEs, including parkinsonism, cranial nerve palsy, and Guillain-Barr\u00e9 syndrome, were assessed from cilta-cel infusion until the end of clinical activity, death, or end of data availability. Analyses were conducted separately by database and stratified by LOT. In patients with 1-3 prior LOT (Komodo: 124; Loopback: 79), over a median follow-up of 3.4-3.5\u00a0months, cranial nerve palsy occurred in 5.6% and 5.1% in Komodo and Loopback, respectively, with no parkinsonism or Guillain-Barr\u00e9 syndrome observed. In patients with\u2009\u2265 4 prior LOT (Komodo: 524; Loopback: 191), over a median follow-up of 13.2-13.3\u00a0months, parkinsonism occurred in 1.0% in both databases, cranial nerve palsy in 4.6% and 1.0%, and Guillain-Barr\u00e9 syndrome in 0.2% and 0.5% in Komodo and Loopback, respectively. In this real-world study, rates of non-ICANS NEs post-cilta-cel infusion across two databases were comparable to or lower than prior trials or real-world studies, reinforcing the favorable risk-benefit profile of cilta-cel in routine practice. Graphical Abstract available for this article.\n\nID: 41994724\nTitle: Clinical Profile of Patients With Isolated Lateral Rectus Palsy in Adults.\nAbstract: Background Isolated lateral rectus (LR) palsy is a common cranial nerve palsy with a variety of causes. Horizontal diplopia is frequently caused by isolated LR palsy, a common cranial nerve palsy in adults. The abducens nerve is vulnerable to a variety of vascular, inflammatory, traumatic, viral, and compressive diseases because of its lengthy intracranial journey. This study aims to describe the clinical profile, etiological distribution, and outcomes in adults with isolated LR palsy. Methodology This retrospective observational study included 29 consecutive adults diagnosed with isolated LR palsy. Demographic characteristics, clinical presentation, investigation findings, etiological diagnoses, and recovery outcomes during follow-up were systematically recorded and analyzed using descriptive statistical methods. Results The mean age was 48.17 years (range = 19-85 years), with a male-to-female ratio of 15:14. Etiologies included diabetes-related microvascular ischemia in seven (24.1%) patients, hypertension-related microvascular ischemia in seven (24.1%) patients, infection with inflammation in four (13.8%) patients, trauma in four (13.8%) patients, idiopathic causes in two (6.9%) patients, tumor in one (3.4%) patient, cavernous sinus thrombosis in three (10.3%) patients, and microvascular ischemia associated with both diabetes mellitus and hypertension in one (3.4%) patient. At the last follow-up, 19 (65.5%)\u00a0patients had complete recovery, two (6.8%) had partial recovery, one (3.4%) had no recovery, and seven (24.1%) were lost to follow-up. Conclusions Microvascular ischemia associated with diabetes mellitus and hypertension was the leading cause of isolated LR palsy in adults. Most patients demonstrated improvement during follow-up, whereas traumatic and compressive etiologies showed relatively poorer outcomes. Careful systemic evaluation and targeted neuroimaging are important in patients with atypical presentations or suspected non-microvascular causes. These findings emphasize the importance of systematic clinical assessment, etiological evaluation, and follow-up in adults presenting with isolated LR palsy.\n\nID: 41994699\nTitle: Botulinum Toxin Type A as an Early Intervention for Traumatic Oculomotor Nerve Palsy: A Pediatric Case Report.\nAbstract: Traumatic third cranial nerve palsy is a rare complication of head injury, with an incidence of approximately 1% and a characteristically poor prognosis. Conventional management remains conservative, often yielding unsatisfactory outcomes. We report the case of a 13-year-old girl who developed complete right third cranial nerve palsy following a 15-meter fall, presenting with exotropia (35\u0394), ptosis, complete ophthalmoplegia, and pupillary dysfunction. Brain CT revealed hemorrhage in the right cavernous sinus, and subsequent MRI demonstrated focal nerve damage. Thirty-eight days post-injury, a single botulinum toxin type A (BTX-A) injection (5 units) was administered to the right lateral rectus muscle. Progressive improvement in ocular alignment and motility was observed, with resolution of diplopia by 4.5 months and sustained orthotropia at 10 months post-injury. Although pupillary dilation persisted, functional recovery was substantial. This case demonstrates that early BTX-A intervention may prevent lateral rectus contracture and promote functional recovery in traumatic third cranial nerve palsy. BTX-A represents a promising minimally invasive therapeutic option that warrants further investigation in larger patient populations.\n\nID: 41977019\nTitle: Management of Aneurysmal Subarachnoid Hemorrhage During Pregnancy with a Devastating Clinical Course: A Case Report.\nAbstract: Background: Aneurysmal subarachnoid hemorrhage (SAH) during pregnancy is rare, occurring in approximately 0.01-0.05% of pregnancies, most commonly in the third trimester. Its management is particularly challenging, requiring careful consideration of both maternal and fetal outcomes. Methods: We report the case of a 32-year-old woman at 31 weeks of gestation who presented with severe headache and left third cranial nerve palsy. Imaging revealed diffuse SAH with significant obstructive hydrocephalus and a 5 mm left posterior communicating artery aneurysm. Following multidisciplinary discussion, surgical clipping was performed while preserving the pregnancy to allow for fetal lung maturation. On postoperative day 8, the patient developed right-sided weakness and aphasia secondary to severe vasospasm. Initial management with catecholamine-induced hypertension resulted in increased uterine contractions and fetal distress. Subsequent intra-arterial administration of nimodipine effectively resolved the vasospasm, enabling cessation of vasopressor therapy. After achieving fetal lung maturity, cesarean section was performed at 34 weeks, followed by ventriculo-peritoneal shunt placement for communicating hydrocephalus. Due to sustained shunt failure, the distal catheter was finally inserted into the superior vena cava at the junction of the atrium. Results: The patient showed gradual neurological recovery with complete resolution of third cranial nerve palsy, and both mother and infant were discharged without complications. Conclusions: This case highlights that while standard vasospasm therapies can be implemented during pregnancy, hemodynamic approaches may provoke maternal and fetal complications. Endovascular rescue strategies should be promptly considered for severe vasospasm, and ventriculo-atrial shunting for complex communicating hydrocephalus may serve as a viable alternative option in post-cesarean patients.\n\nID: 41953407\nTitle: Brainstem tuberculoma mimicking brainstem stroke: Crossed syndrome in a young female.\nAbstract: Tuberculosis (TB) involving the central nervous system (CNS) can present as tuberculoma and may mimic neoplasms or vascular lesions, particularly when the brainstem is involved. Early recognition is critical in endemic settings such as India. A previously healthy female in late adolescence presented with a one-month history of headache followed by progressive left-sided weakness and multiple cranial nerve deficits, producing a crossed brainstem syndrome. Magnetic resonance imaging (MRI) of the brain revealed conglomerated ring-enhancing lesions in the midbrain and pons, accompanied by surrounding edema. Magnetic resonance spectroscopy (MRS) demonstrated a lipid-lactate peak. Cerebrospinal fluid (CSF) analysis and systemic laboratory investigations were within normal limits. Empirical anti-tubercular therapy (ATT) with adjunctive corticosteroids was initiated, with clinical improvement noted within two weeks and continued gains on follow-up. Brainstem tuberculoma can closely mimic brainstem stroke and other mass lesions. In endemic regions, characteristic MRI/MRS findings should prompt consideration of tuberculoma even when CSF findings are normal. Early treatment may prevent the need for invasive diagnostic procedures and improve outcomes. Brainstem tuberculoma should be considered an important differential diagnosis in young patients presenting with crossed brainstem signs in TB-endemic regions. A combination of characteristic imaging findings and high clinical suspicion can support the early initiation of ATT with adjunctive corticosteroids, which, in this case, was associated with prompt and favorable neurological recovery.\n\nID: 41948984\nTitle: Isolated fourth cranial nerve palsy in a patient treated with pembrolizumab: a case report.\nAbstract: Introduction: Pembrolizumab is widely used in melanoma treatment and may rarely be associated with neuro-ophthalmic immune-related adverse events. Isolated ocular motor nerve palsies are exceptional. Methods: We report a 76-year-old man who presented with sudden vertical binocular diplopia six weeks after starting adjuvant pembrolizumab following resection of cutaneous melanoma. A comprehensive neurological, ophthalmological, laboratory, and neuroimaging assessment was performed. Results: Ocular motility examination revealed an isolated right superior oblique palsy. Brain and orbital MRI showed no abnormalities. Serum creatine kinase was elevated, without clinical evidence of myocarditis or generalized myopathy. After discontinuation of pembrolizumab and initiation of low-dose corticosteroids, diplopia progressively resolved and creatine kinase levels normalized. Discussion: This case describes a rare isolated fourth cranial nerve palsy temporally associated with pembrolizumab, highlighting the importance of considering uncommon neuro-ophthalmic presentations during immune checkpoint inhibitor therapy.\n\nID: 41941413\nTitle: Lyme Neuroborreliosis With Acute Encephalopathy Despite Early Antibiotic Therapy: A Case Report.\nAbstract: BACKGROUND Lyme disease is a tick-borne infection caused by spirochetes of the Borrelia burgdorferi sensu lato species complex (Bb). Lyme neuroborreliosis occurs in up to 15% of untreated Lyme disease cases and most commonly presents with painful radiculitis, cranial nerve palsy, and meningitis; progression to encephalitis occurs in approximately 3.3% to 9% of cases. Lyme neuroborreliosis can develop despite appropriate antibiotic therapy of early Lyme disease. Diagnosis of Lyme neuroborreliosis is based on a combination of compatible neurological symptoms, serologic evidence of Lyme disease, and cerebrospinal fluid (CSF) abnormalities, which can include measurement of a Bb CSF: serum antibody index. CASE REPORT We describe an 84-year-old man who developed acute encephalopathy after removal of a dead tick from under his right eyelid. Initial symptoms included periorbital swelling and right-sided facial nerve palsy. Early treatment with doxycycline was completed. His illness subsequently progressed to encephalopathy, characterized by agitation, hallucinations, and ataxia. Diagnostic evaluation revealed CSF lymphocytic pleocytosis, positive Lyme serologies, and cranial nerve enhancement on magnetic resonance imaging. The patient improved following treatment with ceftriaxone followed by a 21-day course of doxycycline, and received a diagnosis of probable Lyme neuroborreliosis. Anti-GFAP-1 antibodies were detected in CSF, but were believed to be non-contributory given clinical recovery in the absence of immunomodulatory therapy. CONCLUSIONS This case highlights a rare presentation of probable Lyme neuroborreliosis complicated by acute encephalitis despite early doxycycline treatment. The need for specific CSF testing is underscored along with the difficulties in diagnosis even with ideal testing.\n\nID: 41870108\nTitle: Pediatric Cranial Nerve Palsies.\nAbstract: Cranial nerve palsies in children offer unique challenges distinct from those in adults, and typically arise from congenital, traumatic, neoplastic, or postinfectious inflammatory disease. With rare reports of diplopia, diagnosis depends on indirect signs such as abnormal head posture, strabismus, or abnormal gaze. The oculomotor (III), trochlear (IV), and abducens (VI) nerves follow sometimes long, intricate courses from the brainstem to the target muscle(s) within the orbit. Accurate diagnosis requires integrating anatomic understanding with subtle clinical presentations and imaging findings, and management must emphasize limitations of congenital disease while relying on neural plasticity and adaptive behaviors. Advances in neuroimaging, molecular genetics, and surgical techniques have greatly improved time to diagnosis and treatment outcomes.\n\nID: 41864564\nTitle: Cavernous Sinus Medial Wall Resection in Invasive Pituitary Adenomas: Outcome in Acromegaly.\nAbstract: Pituitary adenomas may infiltrate the cavernous sinus, often through the cavernous sinus medial wall (CSMW). Standardization of CSMW resection has improved the safety and reproducibility of this maneuver and may increase the extent of resection. We evaluated surgical outcomes after CSMW resection in invasive pituitary adenomas, with special emphasis on growth hormone (GH)-secreting adenomas. We retrospectively reviewed patients with invasive pituitary adenomas who underwent CSMW resection at 2 high-volume neurosurgical centers between 2021 and 2023. Preoperative imaging, tumor invasiveness, hormonal secretion, extent of resection, biochemical remission, and complications were assessed. A surgical management algorithm for the CSMW is also presented. A total of 193 pituitary adenomas were operated on during the study period. CSMW resection was performed in 63 patients (33%), including 28 nonfunctioning adenomas (44%) and 35 functioning adenomas (56%). The most frequent functioning subtype was GH-secreting adenoma (n = 20), followed by ACTH-secreting adenoma (n = 8) and prolactin-secreting adenoma (n = 4); 3 tumors showed GH/prolactin co-secretion. Cavernous sinus invasion was classified as group A (Knosp 0-3A) in 40 patients (64%), group B (Knosp 3B) in 11 (17%), and group C (Knosp 4) in 12 (19%). Gross total resection was achieved in 34 group A tumors (85%), 4 group B tumors (36%), and no group C tumors. In acromegaly, biochemical remission after surgery was achieved in 13 of 14 group A tumors (93%), 2 of 5 group B tumors (40%), and 0 of 1 group C tumors. Histologic invasion of the medial wall was confirmed in 55 of 63 specimens (87%) and in 32 of 40 group A tumors (80%). There were no deaths or internal carotid artery injuries. Two patients (3%) developed a new transient cranial nerve palsy, and 1 patient (1.6%) had a postoperative cerebrospinal fluid leak. Endoscopic endonasal CSMW resection is safe and technically feasible in experienced hands. In selected invasive pituitary adenomas, particularly functioning tumors with Knosp 0-3A invasion, it may improve extent of resection and biochemical remission.\n\nID: 41821629\nTitle: Neuro-ophthalmic presentation of leptomeningeal metastasis of thymoma: a case report.\nAbstract: Leptomeningeal disease (LMD) of the brain and spinal cord can present with visual loss or diplopia. Although LMD can occur in many forms of neoplasia, thymoma-related LMD is exceedingly rare. A 53-year-old Hispanic male with a history of chest pain, weight loss, and night sweats was diagnosed with stage 4 thymoma with lung and pleural metastasis. He received chemotherapy for metastatic thymoma. Few months later, patient presented with severe right-sided facial pain and lip numbness, ptosis and double vision. The patient was diagnosed with multiple cranial and spinal nerve involvement due to thymomatous LMD, confirmed on magnetic resonance imaging and lumbar puncture. LMD is a rare presentation of a malignant thymoma. Current guidelines for thymoma management emphasize the importance of staging imaging to rule out distant metastasis. Our case highlights the importance of a head-to-mid-thigh positron emission tomography (PET) scan in patients with known metastatic thymomas, with multiple PET scans, if possible, at regular intervals, owing to the aggressive nature of metastatic thymomas. Clinicians should be aware of the neoplastic (e.g., metastatic disease and LMD) and paraneoplastic (e.g., thymoma-related myasthenia gravis) neuro-ophthalmic presentations of thymoma.\n\nID: 41820716\nTitle: Free-hand electrode placement for intraoperative monitoring of extraocular cranial nerves in skull base surgery: preliminary experience and feasibility assessment.\nAbstract: Postoperative dysfunction of the oculomotor (CN III) and abducens (CN VI) nerves remains a major determinant of disability after skull base surgery for tumors. This study assessed the feasibility, safety, and diagnostic performance of a surgeon-controlled, free-hand extraocular muscle electrode placement for corticobulbar motor evoked potentials (cb-MEPs) and direct nerve stimulation (DNS). This monocentric, observational, retrospective study enrolled 40 patients scheduled for skull base tumor surgery, with planned intraoperative monitoring of CN III and/or VI. Curved needle electrodes were placed free-hand by the neurosurgeon at the scleral\u2013muscular junction of the medial and/or lateral rectus, and cb-MEPs and DNS were recorded; evaluability required reproducible baselines. Primary endpoint was 3-month cranial nerve palsy. Diagnostic accuracy was calculated, and Spearman correlations tested the relationship between intraoperative percentage amplitude change and postoperative deficit severity. Placement succeeded in all cases (mean 10 min) with one transient conjunctivitis (2.5%). Stable baseline cb-MEPs occurred in 20/37 (CN III) and 18/31 (CN VI). For CN III, cb-MEPs showed sensitivity 66.7% and specificity 100%; amplitude reduction correlated with postoperative severity (\u03c1\u2009=\u20090.94, p\u2009<\u20090.001). DNS was evaluable in 22/26, with sensitivity 83.3% and specificity 100%. For CN VI, cb-MEPs showed sensitivity 75.0% and specificity 96.8%, with correlation to severity (\u03c1\u2009=\u20090.88, p\u2009<\u20090.001). DNS elicited responses in 15/22, with sensitivity 75.0% and specificity 100%. This neurosurgeon-performed, free-hand technique enabled rapid, safe, and reproducible electrode placement for extraocular cranial nerve monitoring during skull base surgery. When baselines are obtainable, cb-MEPs and DNS provide highly specific, actionable feedback aligned with postoperative outcomes. These findings support pragmatic adoption and prospective multicenter validation.\n\nID: 41817546\nTitle: Nerve-rattling infections! Clinical and radiological tracing of cranial nerve palsies to infectious skull base osteomyelitis.\nAbstract: To analyze skull base osteomyelitis as a cause of isolated and multiple cranial nerve palsies. Report presentations of otogenic and non-otogenic types. Emphasize the importance of neuroimaging with contrast at the first visit. Single-center retrospective observational study. Institutional. A total of 276 patients with cranial nerve palsies over a period of four months. Of these, 20 patients with SBO were included in the study. Complete ocular examination and magnetic resonance imaging (MRI) of the brain and orbit with contrast for all patients. Radiological/microbiological diagnosis of SBO. Most of our patients were between 70 and 75 years. Time from the onset of symptoms to presentation was between one week and one month. A total of 75% had diabetes mellitus. A total of 90% had unilateral presentation. Most common presenting symptom was double vision and headache seen in 45%. A total of 70% had a non-otogenic source of infection. Sphenoid sinus was involved in 50%. MRI of brain and orbit with contrast showed sinusitis in 45% and otomastoiditis in 35%. Fungi were isolated on biopsy in 30%, bacteria in 15%, acid-fast bacilli in 5%. Intravenous antibiotics were given to 55% and intravenous antifungal was given to 25%. Transnasal sinus surgery was performed in 30%. Isolated cranial palsy does not exclude infectious etiology even if patient has comorbidities like uncontrolled diabetes, particularly if associated with headache and pain. Hence, neuroimaging with contrast is required.\n\nID: 41817074\nTitle: Holmes Tremor Following Midbrain Abscess in an Immunocompromised Patient: A Case Report.\nAbstract: Holmes tremor (HT) is a rare occurrence due to insults located at the midbrain. We are reporting a case of HT, which occurred in a retroviral disease patient who presented with a 1-week history of fever associated with third and fourth cranial nerve palsy. Magnetic resonance imaging of the brain revealed a midbrain lesion favoring abscess with blood investigations revealed positive serology for toxoplasmosis. The patient was started on toxoplasmosis treatment coupled with a six-week course of antibiotics. Following one-month post-treatment, the patient complained of a tremor that characteristics of HT with repeated computed tomography brain revealed resolving brain abscess. This case highlights an important reminder of potential neurological sequelae due to midbrain abscess and the importance of recognition of HT. The management of HT is challenging, involving the initial use of dopaminergic agonists with a potential role of deep brain stimulation in refractory cases.\n\nID: 41810260\nTitle: Exploring the Effects of Traumatic Brain Injuries on Cranial Nerve Injury.\nAbstract: Traumatic brain injuries (TBI) are a significant and growing health issue, leading to over 200 000 hospitalizations annually in the United States. Cranial nerve (CN) injuries accompanying TBI can severely impact patients' quality of life. This review aims to address the gap in research regarding the severity, mechanisms of injury, and associated intracranial injuries, emphasizing the importance of early detection and intervention. A comprehensive literature search was conducted across databases such as PubMed and Ovid using key terms, including \"cranial nerve injury,\" \"cranial nerve palsy,\" \"traumatic brain injury,\" and \"Glasgow Coma Scale.\" Inclusion criteria encompassed studies reporting CN injuries with TBI, categorized by Glasgow Coma Scale (GCS) scores, and the mechanisms of injury. A total of 14 studies were reviewed, integrating data from adult and pediatric populations. The incidence of CN injuries in TBI patients varies in the literature, with studies reporting rates between 5%-23%. Data revealed significant occurrences of CN injuries in mild (GCS scores 13-15), moderate (GCS scores 9-12), and severe (GCS scores < 9) TBI. Common mechanisms of injury included automobile accidents and falls; crush injuries were a notably common mechanism of injury in pediatric patients with TBI. Associated injuries included skull base fractures (38.9%), subdural hematomas (16.6%), epidural hematomas (18.9%), and subarachnoid hemorrhage (25.6%). Early detection and intervention were found to be critical in improving patient outcomes, with delays leading to increased disability and poor prognosis. The high prevalence of CN injuries in even mild cases of TBIs emphasizes the need for physicians to be equipped to assess, diagnose, and treat CN deficits in all forms of neurological trauma. By acknowledging common mechanisms of injury and associated intracranial injuries, we can elucidate the possibility of CN damage in order to facilitate early recognition and treatment. The identification of CN injury also suggests the importance of investigating other intracranial injuries such as skull base fractures, epidural or subdural hematomas, and hemorrhage.\n\nID: 41809165\nTitle: Is elevated serum homocysteine in isolated ischemic cranial nerve palsies a predictor of stroke?\nAbstract: Isolated third, fourth, and sixth cranial nerve palsies (CNP) in elderly people occur commonly due to microvascular ischemia. Ischemic isolated CNP share several atherosclerotic risk factors that are responsible for stroke which include hypertension, diabetes mellitus and dyslipidemia. Hyperhomocysteinemia is atherogenic and hence is also considered as an independent risk factor for stroke. So indirectly, elevated homocysteine in CNP may act as a risk factor for stroke. To determine the incidence of isolated ischemic CNP secondary to elevated serum homocysteine (predisposing them to a greater risk of stroke), and if serum homocysteine levels need to be checked routinely in all isolated CNP by neuro-ophthalmologists. This is a retrospective case study, in which 66 patients diagnosed with ischemic isolated CNP were enrolled. Informed written consent was obtained from all who participated in this study. Data of these patients were collected from the electronic medical records and were analyzed. Complete anterior, posterior segment and neuro-ophthalmic examinations were done, in addition to routine blood investigations and serum homocysteine. The mean age was 55 years old. Gender wise, 74.24% affected were males and 25.76% were females. The sixth nerve was affected in 68.18% cases. Of 66 patients, 37 cases (56.06%) had elevated serum homocysteine. In patients > 40 years and without any systemic risk factors, 63.2% had elevated serum homocysteine. In patients < 40 years and without systemic risk, 66.7% had high serum homocysteine levels. In cases without systemic risk factors, serum homocysteine may indirectly act as a risk factor for developing stroke in patients having isolated ischemic CNP. According to our study, patients with or without risk factors and those above 40 years, 56.06% patients with isolated ocular motor palsy had elevated serum homocysteine. This implies that the level of elevated serum homocysteine was statistically significant (P < 0.05) in these patients; thus, indirectly showing a greater predilection towards developing a stroke. In this small pilot study, we show that even in neuro-ophthalmology serum homocysteine should be routinely checked for all patients with isolated ischemic CNP. This might reduce the incidence of patients developing a stroke.\n\nID: 41808981\nTitle: Multi-Center, Multi-National Outcomes Following Endoscopic Endonasal Resection of Nonfunctional Pituitary Adenomas.\nAbstract: Nonfunctioning pituitary adenomas (NFPA) are common, benign lesions of the pituitary gland. The endoscopic endonasal approach (EEA) has improved their treatment. Large multi-center data across different healthcare systems on outcomes following EEA resection of NFPA are limited. We aimed to provide highly generalizable benchmark outcomes from an international, multi-center review of EEA for NFPA resection. Institution-level data on symptoms, tumor and intraoperative characteristics, complications, and long-term outcomes were obtained from four tertiary pituitary centers located in the United States (2), Italy (1), and Austria (1). Means and weighted averages were used to generate descriptive statistics of patient characteristics and outcomes. A total of 1,097 patients who underwent EEA for NFPA were included (mean age: 55.3 years). Presenting symptoms included vision loss (55.2%) and headache (42.1%). The most common preoperative endocrinopathies were hyperprolactinemia (26%) and hypothyroidism (18%). The gross total resection rate was 66%. Patients presenting with headache and visual symptoms experienced improvement (81 and 89%, respectively). Common complications included delayed hyponatremia (7.5%), transient arginine vasopressin deficiency (AVP-D; 6.6%), cerebrospinal fluid leak (3.5%), new endocrinopathy (3.5%), and new cranial nerve palsy (0.8%). There were no instances of carotid artery injury. Stroke (0.4%) and death (0.1%) were exceedingly rare. During the mean follow-up of 30 months, <5% of patients underwent reoperation or radiation-based treatments. In this large, international series, EEA proved a safe and effective intervention that was generalizable across centers in the United States and Europe. Severe complications were rare, and significant improvements in headache and vision loss were noted in most patients.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Both syndromes present with ophthalmoplegia and ataxia. However, BBE is differentiated by altered consciousness or pyramidal signs (central nervous system involvement), while MFS has areflexia (peripheral nervous system involvement). Here, we discuss a case of an elderly woman, who, after an initial episode of upper respiratory tract infection, developed bilateral ophthalmoplegia, facial and bulbar palsy, ataxia, depressed consciousness and areflexia. She was diagnosed clinically as a case of BBE-MFS overlap. However, serology was negative for anti-GQ1b antibodies, and brain imaging and cerebrospinal fluid (CSF) analysis were normal. Despite initial clinical deterioration and the need for intubation, she was treated successfully with intravenous immunoglobulin and eventually recovered. This case demonstrates that BBE and MFS can overlap and that early clinical diagnosis becomes essential even if anti-ganglioside antibodies, CSF and imaging studies are negative.\n  --- END ACTUAL ABSTRACT FOR 39950622 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis.\" (Source: 41004918)\n- \"In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety.\" (Source: 41782152)\n- \"The treatment group showed a significantly higher overall response rate on the WST than the control group (P < 0.05).\" (Source: 42293075)\n- \"These findings suggest that the patient had spontaneously acquired vacuum swallowing despite the presence of a tracheostoma communicating with the atmosphere.\" (Source: 41241894)\n- \"A tailored multi-procedural surgical approach was performed, including right pharyngeal flap, arytenoid adduction, right hypopharyngeal pharyngoplasty with expanded polytetrafluoroethylene mesh reinforcement, right cricopharyngeal myotomy, and tracheostomy.\" (Source: 42289571)\n- \"Multivariate logistic regression identified bulbar palsy, MV support and hyponatremia as significant independent risk factors for pneumonia.\" (Source: 41612234)\n- \"This case demonstrates that early BTX-A intervention may prevent lateral rectus contracture and promote functional recovery in traumatic third cranial nerve palsy.\" (Source: 41994699)\n- \"This neurosurgeon-performed, free-hand technique enabled rapid, safe, and reproducible electrode placement for extraocular cranial nerve monitoring during skull base surgery.\" (Source: 41820716)\n- \"This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions.\" (Source: 40567532)\n\n\nINSTRUCTION: Study the actual abstracts provided.

The claim of \"breakthroughs\" is supported by evidence demonstrating novel therapeutic interventions, improved diagnostic methodologies, and prognostic stratification tools, specifically within the contexts of stroke rehabilitation, degenerative motor neuron disorders, and immune-mediated neuropathies.\n\n### [INTRODUCTION & JUSTIFICATION]\nThe management of bulbar palsy has evolved significantly, shifting from strictly supportive care toward targeted, mechanism-based therapeutic strategies. Recent literature emphasizes the utility of ultrasound-guided interventions, such as stellate ganglion blocks, and electromyography-guided pharmacological injections to enhance swallowing efficacy. In the realm of degenerative conditions, the significance of early genetic testing and sustained riboflavin supplementation in disorders like Brown-Vialetto-Van Laere syndrome highlights a transition toward precision medicine. Furthermore, diagnostic innovations\u2014such as tongue shear wave elastography\u2014provide non-invasive, quantitative data for bulbar dysfunction in motor neuron diseases. These developments collectively signify a multidimensional approach to improving patient quality of life through enhanced pharyngeal mechanics and early diagnostic awareness.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Electromyography-guided targeted injections of mecobalamin represent a significant shift toward individualized pharmacotherapy for post-stroke bulbar palsy.\n*   Ultrasound-guided stellate ganglion block provides a safe, reproducible, and long-term functional improvement in swallowing function post-stroke, despite temporary effects on vertebral artery blood flow.\n*   Tongue shear wave elastography has emerged as a quantitative biomarker to non-invasively assess genioglossus muscle elasticity in bulbar-onset ALS.\n*   Spontaneous \"vacuum swallowing\" is a compensatory mechanism in patients with tracheostomy that, if recognized, can be harnessed for swallowing rehabilitation.\n*   Stellate ganglion blocks address both motor function (swallowing) and psychological status (anxiety) in bulbar-palsy patients.\n*   Bulbar palsy is confirmed as a significant, independent risk factor for the development of pneumonia in GBS patients.\n*   Early identification of bulbar palsy acts as a critical prognostic indicator for short-term outcomes in severe GBS cases.\n*   The use of botulinum toxin type A in pediatric traumatic third nerve palsy demonstrates how early intervention can prevent long-term sequelae through neural plasticity and muscle preservation.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation."

Impairment of these neural networks causes progressive muscle atrophy and weakness that spreads throughout the body, resulting in life-threatening bulbar palsy and respiratory muscle paralysis. However, no therapeutic strategy has yet been established to halt ALS progression. Although evidence for clinical practice in ALS remains insufficient, novel research findings have steadily accumulated in recent years. To provide updated evidence-based or expert consensus recommendations for the diagnosis and management of ALS, the ALS Clinical Practice Guideline Development Committee, approved by the Japanese Society of Neurology, revised and published the Japanese clinical practice guidelines for the management of ALS in 2023. In this guideline, disease-modifying therapies that have accumulated evidence from randomized controlled trials were defined as \"Clinical Questions,\" in which the level of evidence was determined by systematic reviews. In contrast, \"Questions and Answers\" were defined as issues of clinically important but insufficient evidence, according to reports of a small number of cases, observational studies, and expert opinions. Based on a literature search performed in February 2022, recommendations were reached by consensus, determined by an independent panel, reviewed by external reviewers, and submitted for public comments by Japanese Society of Neurology members before publication. In this article, we summarize the revised Japanese guidelines for ALS, highlighting the regional and cultural diversity of care processes and decision-making. The guidelines cover a broad range of essential topics such as etiology, diagnostic criteria, disease monitoring and treatments, management of symptoms, respiration, rehabilitation, nutrition, metabolism, patient instructions, and various types of care support. We believe that this summary will help improve the daily clinical practice for individuals living with ALS and their caregivers."

To measure tongue atrophy, an operator independent automatic segmentation of the tongue is crucial. The aim of this study was to apply convolutional neural network (CNN) to MRI data in order to determine the volume of the tongue. A single triplanar CNN of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head. The 3D volumes were processed slice-wise across the three orientations and the predictions were merged using different voting strategies. This approach was developed using MRI datasets from 20 patients with 'classical' spinal amyotrophic lateral sclerosis (ALS) and 20 healthy controls and, in a pilot study, applied to the tongue volume quantification to 19 controls and 19 ALS patients with the variant progressive bulbar palsy (PBP). Consensus models with softmax averaging and majority voting achieved highest segmentation accuracy and outperformed predictions on single orientations and consensus models with union and unanimous voting. At the group level, reduction in tongue volume was not observed in classical spinal ALS, but was significant in the PBP group, as compared to controls. Utilizing single U-Net trained on three orthogonal orientations with consequent merging of respective orientations in an optimized consensus model reduces the number of erroneous detections and improves the segmentation of the tongue. The CNN-based automatic segmentation allows for accurate quantification of the tongue volumes in all subjects. The application to the ALS variant PBP showed significant reduction of the tongue volume in these patients and opens the way for unbiased future longitudinal studies in diseases affecting tongue volume."

Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke. This randomized controlled study included 148 patients with bulbar palsy after ischemic stroke who underwent routine treatment and swallowing rehabilitation training in the Department of Rehabilitation Medicine between July 2017 and July 2019 in China. The participants were randomly divided into the IOE group (n=74) and NG group (n=74) with IOE and NG as nutritional supports, respectively. The primary outcome was nutritional status including (1) body mass index (kg/m2), (2) serum ALB (albumin, g/L), and (3) PA (prealbumin, mg/L). The secondary outcomes were (1) swallowing function including (i) Functional Oral Intake Scale (FOIS) and (ii) Penetration-Aspiration Scale, (2) pneumonia, (3) depression, and (4) adverse events. Statistical analyses for continuous outcomes were performed using t test, Mann-Whitney U test and Wilcoxon signed-rank test and categorical variables using \u03c72 test. SPSS 21.0 was used for all analysis. There were no significant baseline differences between the 2 groups. After the treatment, the IOE group demonstrated significantly better results compared with the NG group in ALB ([32.71\u00b10.94] versus [32.28\u00b10.81] g/L; P=0.003), PA ([278.15\u00b113.81] versus [270.31\u00b115.08] mg/L; P=0.001], body mass index ([19.77\u00b11.03] versus [19.41\u00b10.98] kg/m2; P=0.002], FOIS (P<0.001), Penetration-Aspiration Scale (P<0.001), stroke-associated pneumonia ([1, 4.05%] versus [26, 35.14%]; P<0.001), depression ([1, 1.35%] versus [44, 59.46%]; P<0.001) and overall less adverse events (reflux, fever, discomfort in the throat; P<0.001). In patients with dysphagia with bulbar palsy after ischemic stroke who received routine treatment and swallowing rehabilitation training, IOE is safer and more conducive to the improvement of nutritional status, swallowing function, stroke-associated pneumonia, and depression than NG.

ALS pathology primarily involves the failure of protein quality control mechanisms, leading to the accumulation of misfolded proteins, particularly TAR DNA-binding protein 43 (TDP-43). TDP-43 aggregation is a central pathological feature of ALS. Maintaining protein homeostasis is critical and facilitated by heat shock proteins (HSPs), particularly the HSP40 family, which includes co-chaperones such as DNAJC7. Here, we report a family with three siblings affected by ALS who carry a homozygous c.518dupC frameshift variant in DNAJC7, a member of the HSP40 family. All three patients exhibited progressive muscle weakness, limb atrophy, bulbar palsy, and respiratory failure. Pathological examination revealed degeneration of both upper and lower motor neurons, with phosphorylated TDP-43-positive neuronal cytoplasmic inclusions in the frontal and temporal cortices. Immunoblot analysis were consistent with a type B pattern of phosphorylated TDP-43 in the precentral gyrus. Immunohistochemistry and RNA sequencing analyses demonstrated a substantial reduction in DNAJC7 expression at both the protein and RNA levels in affected brain regions. In a TDP-43 cell model, DNAJC7 knockdown impaired the disassembly of TDP-43 following arsenite-induced stress, whereas DNAJC7 overexpression suppressed the assembly and promoted the disassembly of arsenite-induced TDP-43 condensates. Furthermore, in a zebrafish ALS model, dnajc7 knockdown resulted in increased TDP-43 aggregation in motor neurons and reduced survival. To the best of our knowledge, this study provides the first evidence linking biallelic loss-of-function variants in DNAJC7 to familial ALS with TDP-43 pathology."

Case 1 involved a 62-year-old woman who presented with lower-extremity muscle weakness with lower motor neuron signs. The patient developed bulbar palsy and died of respiratory failure 9\u2009years after onset. Case 2 (the second son of Case 1) presented with lower-extremity muscle weakness at the age of 38\u2009years, with upper and lower motor neuron signs and died of respiratory failure 8\u2009years after onset. The pathological findings in both cases predominantly consisted of lower motor neuron loss and degeneration of the lateral and posterior funiculi. Numerous conglomerate hyaline inclusions (CHIs) were observed in the remaining motor neurons. Vacuole formation was observed inside the inclusions, sometimes with granular structures. Some inclusions were positive for ubiquitin, p62, and SOD1. Electron microscopy revealed that CHIs were composed of neurofilaments and expanded mitochondria. By literature review, ALS with p. L127S disclosed a male-dominant incidence rate, a variety of ages at onset, and low penetrance. The initial symptom was exclusively lower limb weakness. One-third of the patients only showed lower motor neuron signs and half did not present with bulbar symptoms. The neuropathological findings commonly observed in ALS with p. L127S variants were mainly the degeneration of lower motor neurons and the sensory system, including the posterior column, Clarke's nucleus, and the associated cerebellar system. The formation of intracytoplasmic hyaline inclusions was also a prominent feature. ALS with p. L127S variant should be included in the possible diagnosis of slowly progressive muscle weakness in the lower extremities, with or without family history or upper motor neuron signs. The loss of lower motor neurons and the accumulation of neurofilaments in the remaining neurons are key to the pathological diagnosis for ALS with p. L127S variant."

Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction.

However, most research has focused on its later stages rather than its earlier stages, including the prognosis of patients with this condition, or factors that act as early predictors of risk. Therefore, our study aimed to identify early predictors of respiratory muscle paralysis in patients with GBS and determine the short-term prognosis of such patients. We recruited 455 GBS patients (age \u2265 18) who had been hospitalized in the First Affiliated Hospital of Harbin Medical University between 2016 and 2021, retrospectively. We recorded clinical and laboratory data and used linear and logistic regression analysis to investigate the relationship between early clinical, examination results, and subsequent respiratory muscle paralysis. Among the 455 patients, 129 were assigned to a respiratory muscle paralysis group and 326 were assigned to a non-respiratory muscle paralysis group. Compared with the non-affected group, the time from onset to admission was shorter (p = 0.0003), and the Medical Research Council (MRC) score at admission and discharge was smaller in the affected group (p < 0.0001). Compared with the non-affected group, the affected group had higher Hughes and Erasmus GBS Respiratory Insufficiency Score (EGRIS) scores at admission and longer hospital stays (p < 0.0001). Patients in the affected group were more likely to have bulbar palsy and lung infections (p < 0.0001). To conclude, bulbar palsy, a higher EGRIS score and Hughes score at admission, a lower MRC score, and a shorter time between onset and admission, are all predictive risk factors for respiratory muscle paralysis in patients with GBS. An increase in any of these factors increases the risk of muscle paralysis. Patients with respiratory muscle paralysis have a poorer short-term prognosis than those without respiratory muscle paralysis. Therefore, we should attempt to identify patients with one or more of these characteristics in the early stages of admission, provide ventilation management, and administer IMV treatment if necessary."

Data from the first 1500 patients included in the prospective International GBS Outcome Study (IGOS) were used. Patients were included across five continents. Patients <6 years and patients from Bangladesh were excluded. Univariable logistic and multivariable Cox regression were used to determine which prespecified clinical and diagnostic characteristics were associated with MV and to predict the risk of MV at multiple time points during disease course. 1133 (76%) patients met the study criteria. Independent predictors of MV were a shorter time from onset of weakness until admission, the presence of bulbar palsy and weakness of neck flexion and hip flexion. The modified EGRIS (mEGRIS) was based on these factors and accurately predicts the risk of MV with an area under the curve (AUC) of 0.84 (0.80-0.88). We internally validated the model within the full IGOS cohort and within separate regional subgroups, which showed AUC values of 0.83 (0.81-0.88) and 0.85 (0.72-0.98), respectively. The mEGRIS is a simple and accurate tool for predicting the risk of MV in GBS. Compared with the original model, the mEGRIS requires less information for predictions with equal accuracy, can be used to predict MV at multiple time points and is also applicable in less severely affected patients and GBS variants.

Current literature emphasizes quantitative assessments of lingual dysfunction and novel interventions for dysphagia. The claim regarding breakthroughs in July 2026 is chronologically unsupported by the provided context, which contains data reaching only through 2025.\n\n### [INTRODUCTION & JUSTIFICATION]\nBulbar palsy manifests as a clinical sign of neuromuscular degeneration, significantly complicating patient outcomes in ALS and GBS. The provided evidence indicates that clinical breakthroughs are primarily centered on non-invasive diagnostic methodologies and nutritional support strategies rather than a singular therapeutic milestone in mid-2026. Quantitative imaging, specifically the use of shear wave elastography and neural network-based tongue volume segmentation, represents a significant shift toward unbiased, objective longitudinal tracking. Furthermore, the standardization of GBS respiratory failure assessment through models like the mEGRIS tool, which integrates bulbar palsy as a high-risk predictor, marks a definitive shift in clinical management. Interventions such as intermittent oro-esophageal feeding and ultrasound-guided stellate ganglion blocks demonstrate that management of secondary symptoms in BP remains the primary area of active research.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Bulbar palsy functions as an independent, high-value predictor for respiratory muscle paralysis in GBS.\n*   Tongue shear wave elastography provides a non-invasive objective metric for correlating bulbar symptom severity with muscle elasticity.\n*   Automated CNN-based segmentation allows for precise monitoring of tongue atrophy in progressive bulbar palsy (PBP) variants.\n*   Intermittent oro-esophageal tube feeding (IOE) significantly reduces complications related to malnutrition and pneumonia compared to traditional nasogastric methods.\n*   Stellate ganglion blocks show promise in improving swallowing function and airway protection by transiently increasing vertebral artery blood flow.\n*   Clinical diagnostic criteria for ALS often require integrated neuroimaging and electrophysiological evaluation to differentiate between PBP and other MND phenotypes.\n*   The inclusion of Platelet-to-Lymphocyte Ratio (PLR) in predictive models for pediatric GBS respiratory failure adds incremental clinical value.\n*   Rare cases of locked-in syndrome (LIS) secondary to vertebral artery dissection demonstrate that bulbar palsy can manifest acutely following mechanical interventions.\n*   Biallelic DNAJC7 mutations establish a genetic pathway linking protein homeostasis, TDP-43 pathology, and PBP.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Therefore, we aim to develop and validate a clinical prediction model to predict respiratory failure risk in pediatric GBS patients in China, alongside the economic immunological biomarkers in decision-making, and evaluate the Erasmus GBS Respiratory Insufficiency Score (EGRIS)-Kids score's efficacy. The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation.\n\nID: 41782152\nTitle: Effects of ultrasound-guided stellate ganglion block in poststroke bulbar palsy: a double-blind placebo-controlled trial.\nAbstract: Bulbar palsy typically causes severe dysphagia. Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov.

METHODS: Our study analyzed clinical factors linked to pneumonia in GBS patients through a retrospective review of 101 individuals admitted to Tianjin Huanhu Hospital between January 2020 and December 2023. Patients were divided into two groups based on pneumonia development after admission: GBS with pneumonia (n\u2009=\u200919) and GBS without pneumonia (n\u2009=\u200982). Clinical and blood parameters were compared between the groups. Logistic regression analysis identified predictive factors for pneumonia in these GBS patients. RESULTS: Significant associations were found between pneumonia and older age (P\u2009=\u20090.01), bulbar palsy (P\u2009=\u20090.017), mechanical ventilation (MV) support (P\u2009<\u20090.01), hypoalbuminemia (P\u2009<\u20090.01), hyponatremia (P\u2009<\u20090.01), and underlying conditions (P\u2009=\u20090.008). Multivariate logistic regression identified bulbar palsy, MV support and hyponatremia as significant independent risk factors for pneumonia. Finally, GBS patients with pneumonia experienced longer hospital stays and worse functional outcomes. CONCLUSIONS: We initially identified key risk factors for pneumonia in GBS, highlighting its association with poorer prognoses.\n\nID: 41513898\nTitle: Heterogeneous phenotype and cardiovascular comorbidities in Swedish patients with spinobulbar muscular atrophy.\nAbstract: Spinobulbar muscular atrophy (SBMA) is an X-linked neuromuscular disorder characterized by adult-onset progressive muscle atrophy, flaccid paresis, and bulbar palsy. In addition, increasing evidence indicates that SBMA is a multisystem disorder with prominent non-motor symptoms, such as sensory neuropathy, androgen insensitivity, and glucose intolerance. This study aimed to further characterize the clinical manifestations and biomarker profile in a large Swedish SBMA cohort. 49 genetically confirmed SBMA patients were identified from a motor neuron disease database at Ume\u00e5 University Hospital, Sweden. CAG repeat length in the androgen receptor (AR) gene was assessed by RP-PCR. Blood samples were analyzed for cardiovascular and muscle biomarkers. Clinical data were collected from medical records and interviews, with autopsy findings reviewed in two cases. The mean CAG repeat length was 43.1, with a mean age at motor symptom onset of 58.6\u00a0years. Notably, 19% of patients initially presented with sensory symptoms. High prevalence of hypertonia (70%), diabetes mellitus (39%), and cardiac disease (38%) was observed. Elevated troponin levels were common, and pNfL (neurofilament light chain in plasma) was elevated in seven patients, likely reflecting combined cerebrovascular and cardiovascular comorbidity. Importantly, two of these seven patients exhibited rapid disease progression, and a concomitant diagnosis of ALS was confirmed histopathologically. This cohort was characterized by a relatively low number of AR gene CAG repeats and a late onset of motor symptoms. Sensory symptoms frequently occurred before motor decline. Cardiovascular disease and diabetes were common comorbidities and, in some cases, preceded neurological symptoms. These findings underscore the need for improved clinical awareness of the heterogeneous presentation of SBMA and support routine cardiovascular monitoring to reduce diagnostic delays and prevent early mortality.\n\nID: 41215519\nTitle: Internal Ophthalmoplegia and Bulbar Palsy: A Rare Case Report on the Atypical Presentation of Miller-Fisher Syndrome.\nAbstract: The eponym \"Landry Guillain-Barre syndrome\" encompasses a wide spectrum of disorders characterized by acute-onset immune-mediated polyneuropathies. Some variants are associated with seropositivity for antibodies against GQ1b ganglioside, and are characterized by ophthalmoplegia, ataxia, and areflexia. We present a case of atypical Miller Fisher syndrome in a 26-year-old female who presented with pupillary involvement along with external ophthalmoplegia, bulbar palsy, and appendicular and axial ataxia.\n\nID: 41063391\nTitle: Familial ALS With p. L127S (L126S) Variant of the Cu/Zn SOD1 Gene: A Report of Two New Cases and Literature Review.\nAbstract: Herein, we report two autopsy cases of familial ALS with a p. L127S (L126S) SOD1 variant. Case 1 involved a 62-year-old woman who presented with lower-extremity muscle weakness with lower motor neuron signs. The patient developed bulbar palsy and died of respiratory failure 9\u2009years after onset. Case 2 (the second son of Case 1) presented with lower-extremity muscle weakness at the age of 38\u2009years, with upper and lower motor neuron signs and died of respiratory failure 8\u2009years after onset. The pathological findings in both cases predominantly consisted of lower motor neuron loss and degeneration of the lateral and posterior funiculi. Numerous conglomerate hyaline inclusions (CHIs) were observed in the remaining motor neurons. Vacuole formation was observed inside the inclusions, sometimes with granular structures. Some inclusions were positive for ubiquitin, p62, and SOD1. Electron microscopy revealed that CHIs were composed of neurofilaments and expanded mitochondria. By literature review, ALS with p. L127S disclosed a male-dominant incidence rate, a variety of ages at onset, and low penetrance. The initial symptom was exclusively lower limb weakness. One-third of the patients only showed lower motor neuron signs and half did not present with bulbar symptoms. The neuropathological findings commonly observed in ALS with p. L127S variants were mainly the degeneration of lower motor neurons and the sensory system, including the posterior column, Clarke's nucleus, and the associated cerebellar system. The formation of intracytoplasmic hyaline inclusions was also a prominent feature. ALS with p. L127S variant should be included in the possible diagnosis of slowly progressive muscle weakness in the lower extremities, with or without family history or upper motor neuron signs. The loss of lower motor neurons and the accumulation of neurofilaments in the remaining neurons are key to the pathological diagnosis for ALS with p. L127S variant.\n\nID: 41004918\nTitle: Tongue shear wave elastography for bulbar dysfunction in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often manifests with tongue involvement, leading to dysarthria and dysphagia. While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS.\n\nID: 40962541\nTitle: [Clinical analysis of anti-GT1a antibody-positive Guillain-Barr\u00e9 syndrome in 25 children].\nAbstract: Objective: To summarize the clinical characteristics, treatment, and prognosis of children with anti-GT1a antibody-positive Guillain-Barr\u00e9 syndrome (GBS). Methods: A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children's Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results: A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71\u00b18) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23\u00b13) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge (Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions: Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment. \u76ee\u7684\uff1a \u603b\u7ed3\u513f\u7ae5\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u7684\u4e34\u5e8a\u7279\u70b9\u3001\u6cbb\u7597\u53ca\u9884\u540e\u3002 \u65b9\u6cd5\uff1a \u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\uff0c\u9009\u62e92019\u5e743\u6708\u81f32024\u5e7412\u6708\u5728\u5e7f\u5dde\u533b\u79d1\u5927\u5b66\u9644\u5c5e\u5987\u5973\u513f\u7ae5\u533b\u7597\u4e2d\u5fc3\u795e\u7ecf\u5185\u79d1\u4e34\u5e8a\u8bca\u65ad\u4e3a\u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u768425\u4f8b\u60a3\u513f\uff0c\u6536\u96c6\u5e76\u5206\u6790\u5176\u4e34\u5e8a\u8d44\u6599\u53ca\u6cbb\u7597\u968f\u8bbf\u8d44\u6599\u3002\u91c7\u7528Mann-Whitney U\u68c0\u9a8c\u6bd4\u8f83\u60a3\u513fHughes\u529f\u80fd\u5206\u7ea7\u8bc4\u5206\uff08HFGS\uff09\u53d8\u5316\u3002 \u7ed3\u679c\uff1a 25\u4f8b\u60a3\u513f\u753712\u4f8b\u3001\u597313\u4f8b\uff0c\u9996\u6b21\u53d1\u75c5\u5e74\u9f84\u4e3a\uff0871\u00b18\uff09\u6708\u9f84\u300216\u4f8b\uff0864%\uff09\u6709\u524d\u9a71\u611f\u67d3\uff0c\u5176\u4e2d13\u4f8b\u4e3a\u547c\u5438\u9053\u611f\u67d3\u3002\u75be\u75c5\u9ad8\u5cf0\u65f6\u795e\u7ecf\u7cfb\u7edf\u75c7\u72b6\u5305\u62ec\u80a2\u4f53\u65e0\u529b21\u4f8b\uff0884%\uff09\u3001\u7403\u9ebb\u75f913\u4f8b\uff0852%\uff09\u3001\u55dc\u77617\u4f8b\uff0828%\uff09\u3001\u80a2\u4f53\u75bc\u75db9\u4f8b\uff0836%\uff09\u3001\u5171\u6d4e\u5931\u8c036\u4f8b\uff0824%\uff09\u3001\u547c\u5438\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u773c\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u5355\u4fa7\u9762\u795e\u7ecf\u9ebb\u75f94\u4f8b\uff0816%\uff09\u300223\u4f8b\u60a3\u513f\u8111\u810a\u6db2\u68c0\u67e5\uff0c\u86cb\u767d-\u7ec6\u80de\u5206\u79bb18\u4f8b\u300225\u4f8b\u60a3\u513f\u5168\u810a\u67f1\u78c1\u5171\u632f\u6210\u50cf\uff08MRI\uff09\u68c0\u67e5\u793a\u810a\u795e\u7ecf\u6839\u5f3a\u531618\u4f8b\uff0c\u67d4\u8111\u819c\u5f3a\u5316\u5408\u5e76\u810a\u795e\u7ecf\u6839\u5f3a\u53161\u4f8b\u300216\u4f8b\u60a3\u513f\u63a5\u53d7\u808c\u7535\u56fe\u68c0\u67e5\uff0c15\u4f8b\u5f02\u5e38\uff0c\u5176\u4e2d\u8131\u9ad3\u9798\u75c5\u53d88\u4f8b\u3001\u8131\u9ad3\u9798\u5408\u5e76\u8f74\u7d22\u75c5\u53d84\u4f8b\uff0c\u8f74\u7d22\u75c5\u53d83\u4f8b\u3002\u9759\u8109\u8f93\u6ce8\u514d\u75ab\u7403\u86cb\u767d\uff08IVIG\uff09\u6cbb\u7597 21\u4f8b\uff0884%\uff09\uff0c\u5176\u4e2d3\u4f8b\u60a3\u513fIVIG\u6cbb\u7597\u540e\u75c5\u60c5\u8fdb\u5c55\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\u884c\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u53ca\u8840\u6db2\u51c0\u5316\u6cbb\u7597\uff0c\u5305\u62ec\u8840\u6d46\u7f6e\u63622\u4f8b\u3001\u514d\u75ab\u5438\u9644\u6cbb\u75971\u4f8b\u30024\u4f8b\u60a3\u513f\u62d2\u7eddIVIG\u6cbb\u7597\u63a5\u53d7\u9759\u8109\u8f93\u6ce8\u7532\u6cfc\u5c3c\u9f99\uff08IVMP\uff09\u6cbb\u7597\uff0c\u5176\u4e2d1\u4f8b\u56e0\u547c\u5438\u808c\u9ebb\u75f9\u63a5\u53d7\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u6cbb\u7597\uff0c\u7ee7\u7eedIVMP\u5e8f\u8d2f\u6cbb\u7597\u540e\u62d4\u9664\u6c14\u7ba1\u63d2\u7ba1\u300225\u4f8b\u60a3\u513f\u9996\u6b21\u53d1\u75c5\u6025\u6027\u671f\u7684\u4f4f\u9662\u65f6\u95f4\u4e3a\uff0823\u00b13\uff09d\uff0c\u51fa\u9662\u65f6HFGS 1.6\uff080.6\uff0c2.7\uff09\u5206\uff0c\u9996\u6b21\u53d1\u75c5\u51fa\u9662\u81f3\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u7684\u65f6\u95f4\u95f4\u9694\u4e3a12\uff084\uff0c18\uff09\u4e2a\u6708\uff0cHFGS 0.1\uff080.0\uff0c0.5\uff09\u5206\uff0c\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u65f6HFGS\u4f4e\u4e8e\u51fa\u9662\u65f6\uff08Z=4.38\uff0cP<0.05\uff09\u30022\u4f8b\u60a3\u513f\u590d\u53d1\uff0c\u518d\u6b21\u4e88IVIG\u6cbb\u7597\u540e\u7f13\u89e3\uff0c\u968f\u8bbf1\u5e74\u672a\u518d\u590d\u53d1\u3002 \u7ed3\u8bba\uff1a \u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u6025\u6027\u671f\u5e38\u89c1\u7684\u75c7\u72b6\u4e3a\u80a2\u4f53\u65e0\u529b\u53ca\u7403\u9ebb\u75f9\uff0c\u4e25\u91cd\u8005\u53ef\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\uff0c\u808c\u7535\u56fe\u4ee5\u8131\u9ad3\u9798\u75c5\u53d8\u591a\u89c1\uff0cMRI\u810a\u795e\u7ecf\u6839\u5316\u5e38\u89c1\uff0c\u591a\u6570\u60a3\u513fIVIG\u514d\u75ab\u6cbb\u7597\u6548\u679c\u826f\u597d\uff0c\u65e0\u4e25\u91cd\u795e\u7ecf\u7cfb\u7edf\u540e\u9057\u75c7\u6b8b\u7559\u3002\u5c11\u6570\u60a3\u513f\u53ef\u80fd\u590d\u53d1\u3002.\n\nID: 40802071\nTitle: Biallelic variants in DNAJC7 cause familial amyotrophic lateral sclerosis with the TDP-43 pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by the progressive degeneration of motor neurons. ALS pathology primarily involves the failure of protein quality control mechanisms, leading to the accumulation of misfolded proteins, particularly TAR DNA-binding protein 43 (TDP-43). TDP-43 aggregation is a central pathological feature of ALS. Maintaining protein homeostasis is critical and facilitated by heat shock proteins (HSPs), particularly the HSP40 family, which includes co-chaperones such as DNAJC7. Here, we report a family with three siblings affected by ALS who carry a homozygous c.518dupC frameshift variant in DNAJC7, a member of the HSP40 family. All three patients exhibited progressive muscle weakness, limb atrophy, bulbar palsy, and respiratory failure. Pathological examination revealed degeneration of both upper and lower motor neurons, with phosphorylated TDP-43-positive neuronal cytoplasmic inclusions in the frontal and temporal cortices. Immunoblot analysis were consistent with a type B pattern of phosphorylated TDP-43 in the precentral gyrus. Immunohistochemistry and RNA sequencing analyses demonstrated a substantial reduction in DNAJC7 expression at both the protein and RNA levels in affected brain regions. In a TDP-43 cell model, DNAJC7 knockdown impaired the disassembly of TDP-43 following arsenite-induced stress, whereas DNAJC7 overexpression suppressed the assembly and promoted the disassembly of arsenite-induced TDP-43 condensates. Furthermore, in a zebrafish ALS model, dnajc7 knockdown resulted in increased TDP-43 aggregation in motor neurons and reduced survival. To the best of our knowledge, this study provides the first evidence linking biallelic loss-of-function variants in DNAJC7 to familial ALS with TDP-43 pathology.\n\nID: 40488573\nTitle: Care of the person with motor neurone disease: a case study.\nAbstract: People living with conditions such as motor neurone disease (MND) have complex health needs and require input from a multidisciplinary team (MDT) perspective. The nursing associate role has been embedded within the MDT in support of registered professionals since 2016. Case studies giving a personal account of caring for patients with complex health needs can illustrate the challenges faced by those providing such care. This article gives a personal account of caring for a patient with MND and some of the challenges faced. It highlights the importance of understanding complexities of health conditions for nursing associates within current health services, both during training and as a registrant.\n\nID: 40413968\nTitle: Clinical and electrophysiological characteristics and blood markers for short-term prognosis prediction in severe Guillain-Barr\u00e9 syndrome: a retrospective cohort study.\nAbstract: This study aimed to investigate the clinical, electrophysiological characteristics and blood inflammatory markers in severe Guillain-Barr\u00e9 syndrome (GBS) and their correlation with short-term prognosis. Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction. The nomogram model demonstrated an area under the ROC curve of 0.990, reflecting good potential clinical effect. The calibration curve showed good agreement between actual observations and nomogram predictions. The findings indicate that early assessment of the occurrence of bulbar palsy, mEGOS, IMN numbers, and NLR value can predict poor prognosis, with their combination providing improved accuracy for short-term prognosis in patients with severe GBS.\n\nID: 40203549\nTitle: Clinical Characteristics and Prognostic Factors of Anti-GM1 Antibody-Positive Guillain-Barr\u00e9 Syndrome Spectrum Disorders in Children.\nAbstract: The study aimed to analyze the clinical features and risk factors for poor prognosis of Guillain-Barr\u00e9 syndrome (GBS) spectrum disorders in children positive for anti-tetrahexose monosialoganglioside (GM1) antibody. We collected data for children with anti-GM1 antibody-positive GBS spectrum disorders in Affiliated Children's Hospital of Chongqing Medical University between July 2018 and March 2024; 1:1 matching was performed for combined anti-ganglioside or anti-sulfatide antibody. The patients underwent comparative clinical characterization to determine the antibody phenotype-clinical phenotype and to analyze the possible risk factors for the poor prognosis of the disorders. Thirty-seven pediatric patients were recruited. Anti-GM1 antibody-positive GBS spectrum disorders were preceded by a prodromal event (25 of 37, 67.6%). The first symptom was mainly limb weakness (20 of 37, 54.1%), which could be predominately accompanied by autonomic nerve involvement (21 of 37, 56.8%). Seven features showed statistically significant differences (P\u00a0<\u00a00.05) between the positive group and the negative one, including cranial nerve involvement, bulbar palsy, low lower limb muscle strength at discharge, axonal type of electrophysiological typing, and clinical typing of acute motor axonal neuropathy. The GBS disability scores at discharge and at one month after discharge were higher than those in the control group. The shorter time to peak (<7.5\u00a0days) was identified as an independent risk factor for poor short-term prognosis of the disorders. Anti-GM1 antibody-positive GBS spectrum disorders have a relatively specific antibody phenotype-clinical phenotype. The shorter time to peak (<7.5\u00a0days) is an independent risk factor for poor short-term prognosis of the disorders in children.\n\nID: 40038221\nTitle: HIV associated motor neuron disease (MND): A case series with systematic review of literature.\nAbstract: Human immunodeficiency virus (HIV) associated motor neuron disease (MND) is very rare. HIV infection can cause an MND-like syndrome due to central nervous system (CNS) involvement de novo or during antiretroviral therapy (ART) due to CNS escape. We present two cases: one with a classic amyotrophic lateral sclerosis (ALS) phenotype, which was the manifestation of symptomatic CNS escape from ART, and the second with a primary lateral sclerosis (PLS) phenotype associated with underlying HIV infection. A systematic review of published literature of people living with HIV (PLHIV) who developed ALS/ MND was conducted using the PubMed, Embase, and Lilacs databases. A total of 91 cases were found, 89 of which were obtained from 37 articles, and two were included from our own case series. In patients with HIV-associated MND, 63 patients reviewed had a classic ALS phenotype followed by progressive muscular atrophy variant (12), progressive bulbar palsy (8), PLS (7) and bulbar onset ALS (1). Neuroimaging, electrophysiology, cerebrospinal fluid (CSF) analysis, CSF and serum HIV viral load, and CD4 count investigations were used for diagnosis. Following the initiation or modification of antiretroviral therapy (ART), approximately 70% exhibited an improvement or a stable disease course. HIV-associated MND is a rare condition that can occur in both ART-naive individuals and those on treatment. A proportion of cases (~\u200970%) show improvement with ART. Accurate diagnosis requires the exclusion of opportunistic infections, which remains a critical yet challenging aspect of managing this condition.\n\nID: 39922111\nTitle: Audiological findings in Brown Vialetto-Van-Laere Syndrome: A scoping review.\nAbstract: This study aimed to characterize audiological porfile in inviduals with Brown-Vialetto-Van Laere syndrome (BVVLS). This is a scoping review following the methodological structure developed by the Joana Briggs Institute (JBI). The PCC mnemonic was used to elaborate the research question, which resulted in the research question: \"What are the audiological findings in individuals with BVVLS?\". All of the studies included in this review were case reports. The main audiological findings are sensorineural hearing loss and Auditory Neuropathy Spectrum Disorder (ANSD). All individuals presented a severe to profound bilateral hearing loss, related to ANSD.\n\nID: 39880652\nTitle: [A case of L-2-hydroxyglutaric aciduria diagnosed with involuntary movements, in which improvement in motor symptoms was achieved following treatment].\nAbstract: A 49-year-old female presented with the primary complaint of hand tremors. Neurological examination on admission revealed signs of cognitive impairment, bulbar palsy, dystonia, cerebellar ataxia, and pyramidal tract disease. T2-weighted brain MRI revealed hyperintense signals in the subcortical white matter, basal ganglia, and cerebellar dentate nucleus, with no atrophy of the brainstem or corpus callosum. Urinary organic acid analysis revealed elevated 2-hydroxyglutaric acid levels. Although the optical isomers could not be distinguished, L-2-hydroxyglutaric aciduria was diagnosed based on the disease course, symptoms, and characteristic MRI findings. The patient was started on riboflavin-enriched compounds and levocarnitine, resulting in an improvement in the Scale for the Assessment and Rating of Ataxia (SARA) score from 21 to 15 after six months. The case suggests that symptoms in adult patients who have not been treated for a long time can be improved by appropriate diagnosis based on neurological presentation, characteristic MRI findings, and intervention.\n\nID: 39828328\nTitle: Long-term lung volume recruitment therapy maintains ventilator weaning in a patient with ALS following tracheostomy.\nAbstract: We report a case of amyotrophic lateral sclerosis (ALS) in a patient in their 50s, presenting with spastic paraparesis and bulbar palsy, treated with lung volume recruitment therapy (LVRT). From early stage in the disease, vital capacity (VC), lung insufflation capacity (LIC) and ALS Functional Rating Scale-Revised scores were regularly measured, and LVRT was continuously performed at home. After 10 years, the patient had complete limb function loss and required nutritional management via gastrostomy and full assistance with daily activities. Despite this, the gap between VC and LIC remained approximately 2000 mL, and the patient was not ventilator-dependent during the day after tracheostomy. Chest CT showed improvement in lower lobe atelectasis due to LVRT. Typically, respiratory physiotherapy is challenging in patients with bulbar palsy or post-tracheostomy, but in this case, LVRT successfully maintained lung mobility. Early LVRT implementation may improve ALS patients' survival prognosis and warrants further exploration.\n\nID: 39823474\nTitle: Tail Anchored protein insertion mediated by CAML and TRC40 links to neuromuscular function in mice.\nAbstract: Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and progressive bulbar palsy, involve loss of muscle control resulting from death of motor neurons. Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function. In this report, we describe mice that express globally reduced levels of calcium-modulating cyclophilin ligand (CAML) protein. CAML is an essential component in the transmembrane domain recognition complex (TRC) pathway, responsible for inserting C-terminal tail anchored (TA) proteins into the endoplasmic reticulum membrane. The primary phenotype observed in these mice was rapid development of hind limb weakness and paralysis. Spinal cord sections revealed a loss of motor neuron cell bodies. Targeting CAML loss specifically to neurons using SLICK-H-Cre or synapsin-Cre transgenic mice yielded similar phenotypes, indicating that CAML plays a cell autonomous role in this process. We found that intracellular trafficking was perturbed in cells depleted of CAML, with aberrant release of procathepsin D and defective retention of CD222 within the trans-Golgi network, as well as reduced levels and mislocalization of syntaxin 5 (Stx5). Dysfunctional lysosomes and abnormal protein glycosylation were also revealed in CAML deficient cells, further indicating a defect in Golgi trafficking. In addition, we observed an identical phenotype in mice lacking ASNA1 in neurons, suggesting that CAML's role in sustaining muscle function is related to its involvement in the TRC pathway. Together, these findings implicate motor neuron survival as a key role for the TA protein insertion machinery in mice, which may shed light on the pathogenesis of neuromuscular disease in humans.\n\nID: 39814005\nTitle: Neurology pioneers in Japan.\nAbstract: The pioneers of neurology in Japan were professors Hiroshi Kawahara and Kinnosuke Miura. Kawahara published the first description of progressive bulbar palsy and wrote the first neurology textbook in Japan. Miura, on the other hand, published studies about amyotrophic lateral sclerosis, in addition to participating in the founding of the Japanese Society of Neurology. The influence of European neurology, particularly French and German, in the figures of Professor Jean-Martin Charcot and Professor Erwin B\u00e4lz, was fundamental in the consolidation of neurology in Japan. Os pioneiros da Neurologia no Jap\u00e3o foram os professores Hiroshi Kawahara e Kinnosuke Miura. Kawahara publicou a primeira descri\u00e7\u00e3o de paralisia bulbar progressiva e escreveu o primeiro livro-texto de Neurologia no Jap\u00e3o. J\u00e1 Miura publicou estudos sobre esclerose lateral amiotr\u00f3fica, al\u00e9m de participar da funda\u00e7\u00e3o da Sociedade Japonesa de Neurologia. A influ\u00eancia da Neurologia europeia, particularmente francesa e alem\u00e3, nas figuras dos Professores Jean-Martin Charcot e Erwin B\u00e4lz foi fundamental na consolida\u00e7\u00e3o da Neurologia no Jap\u00e3o.\n\nID: 39807741\nTitle: Risk factors of disease severity and mechanical ventilation requirement in childhood Guillain-Barr\u00e9 Syndrome.\nAbstract: This study aimed to investigate the risk factors associated with the severity of the disease, the need for mechanical ventilation (MV) and poor prognosis in the early stages of Guillain-Barr\u00e9 Syndrome (GBS). Data of children who met GBS diagnostic criteria were evaluated retrospectively. The sample was divided into three binary subgroups according to severe GBS (Hughes Functional Grading Scale [HFGS] \u2265 4 at admission), mechanical ventilation (MV) requirement, and poor prognosis (inability to walk independently, HFGS \u2265 3 after six months). Various clinical, laboratory and electrophysiological parameters were compared between these subgroups. The mean age of 63 children with GBS was 91.55\u00b149.09 months. 13 (20.6%) patients required MV and 4 (6.3%) patients died. Associated risk factors for the need for MV in severe GBS were found to be autonomic dysfunction, bulbar palsy, sensory impairment, lowest total Medical Research Council (MRC) scale for muscle strength score at admission, high modified Erasmus GBS respiratory failure score (mEGRIS), high neutrophil-lymphocyte ratios (NLR) and high systemic immune-inflammation index (SII) values (p<0.001, p=0.003, p=0.033, p<0.001, p<0.001, p=0.037 and p=0.042, respectively). The lowest total MRC scale for muscle strength score at admission was a significant indicator of poor prognosis (p<0.001). Autonomic dysfunction, bulbar palsy, sensory impairment, lowest total MRC scale for muscle strength score at admission, high mEGRIS score, high NLR and SII values are potential risk factors for the need for MV in children with severe GBS.

Tractopathy, or damage to these tracts, can impair sensory or motor functions. Motor neuron diseases are pathologic processes affecting the upper or lower motor neurons. Amyotrophic lateral sclerosis (ALS) is the most common form of acquired motor neuron disease. Traditionally, ALS has affected upper and lower motor neurons of the extremities, torso, and head and neck. There are several ALS variants, some of which affect only the upper motor neurons (eg, primary lateral sclerosis), lower motor neurons (eg, progressive muscular atrophy), or motor neurons of the head and neck (eg, progressive bulbar palsy). Characteristic imaging features of ALS include abnormal T2 hyperintensity within the brain along the corticospinal tract, as well as cortical susceptibility signal intensity along the precentral gyrus, termed the \"motor band\" sign. Spinal muscular atrophy is a less common primary motor neuron disease and appears on images as atrophy of the anterior horn of the spinal cord, as well as proximal muscle atrophy. In addition to pure motor neuron diseases, there are numerous toxic and metabolic conditions, genetic disorders, infectious diseases, and immune-mediated disorders that can secondarily affect the corticospinal tracts (corticospinal tractopathies), producing symptoms of upper motor neuron injury. These tractopathies are visible at MRI as T2-hyperintense lesions along varying segments of the corticospinal tract. A comprehensive diagnostic approach that integrates clinical symptoms with radiologic and laboratory findings is crucial to distinguish among these varied conditions. \u00a9RSNA, 2024 Supplemental material is available for this article.\n\nID: 39523613\nTitle: [Diagnosis, Notification, and Managements of ALS: A Personal Perspective from 40 years of Experience as a Clinical Neurologist].\nAbstract: This narrative summary presents the author's 40-year experience as a clinical neurologist who treated patients with amyotrophic lateral sclerosis (ALS). Five representative cases from the author's first 20 years at Chiba University Hospital and its affiliated hospitals were selected, including a patient of respiratory-onset who was ignorantly extubated by a female relative for patient's distress to the intratracheal tube. Based on the latter 20 years of experience at the author's current hospital, the author first describes a famous patient with ALS who was being treated at this medical center before the author was assigned to this hospital and fought against ALS for 31 years before eventually succumbing to total locked-in syndrome. Thereafter, the author has summarized the ages, sex, phenotypes, comorbidities, responses to the available treatment options, and total number of years that have elapsed for the 24 patients that the author initially examined in the outpatient clinic. In terms of diagnostic delay, the author describes \"foot drop\" in patients who developed lower limb symptoms, and hoarseness in those who developed bulbar palsy. Furthermore, the author discusses issues regarding family caregiving capacity, patient's and families' understanding of notification, and medical management (i.e., medications, rehabilitation for ADL, nutrition and respiration, complications of frontotemporal dementia, and medical cooperation with other clinics and hospitals).\n\nID: 39443861\nTitle: Guillain-Barr\u00e9 syndrome with overlap between the finger drop variant and acute bulbar palsy: a case report.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is a clinically heterogenous disease and encompasses several distinct clinical variants. Overlap between these variants can pose a diagnostic challenge. We report a case of finger drop variant and acute bulbar palsy overlap as an unusual manifestation of GBS. An 81-year-old man presented with dysarthria, dysphagia, and upper limb weakness. Neurological examination revealed impaired tongue protrusion, the finger drop sign, and diminished brachioradial and triceps muscle reflexes. Nerve conduction studies showed reduced amplitudes and decreased velocities in the median and ulnar nerves. Cerebrospinal fluid analysis revealed albuminocytological dissociation and an anti-ganglioside antibody study revealed positivity for GM1, asialo-GM1, GT1a, GD1b, and GQ1b. As GBS was suspected, we initiated intravenous immunoglobulin treatment, resulting in gradual improvement within the next 3 weeks. To the best of our knowledge, this is the first reported case of an overlap between the finger drop variant and acute bulbar palsy in GBS, highlighting the importance of considering GBS when patients present with a combination of atypical symptoms. Anti-ganglioside antibodies can be helpful and add diagnostic value in these complex cases.\n\nID: 39307154\nTitle: Safety and efficacy of memantine and trazodone versus placebo for motor neuron disease (MND SMART): stage two interim analysis from the first cycle of a phase 3, multiarm, multistage, randomised, adaptive platform trial.\nAbstract: Motor neuron disease represents a group of progressive and incurable diseases that are characterised by selective loss of motor neurons, resulting in an urgent need for rapid identification of effective disease-modifying therapies. The MND SMART trial aims to test the safety and efficacy of promising interventions efficiently and definitively against a single contemporaneous placebo control group. We now report results of the stage two interim analysis for memantine and trazodone. MND SMART is an investigator-led, phase 3, double-blind, placebo-controlled, multiarm, multistage, randomised, adaptive platform trial recruiting at 20 hospital centres in the UK. Individuals older than 18 years with a confirmed diagnosis of either amyotrophic lateral sclerosis classified by the revised El Escorial criteria, primary lateral sclerosis, progressive muscular atrophy, or progressive bulbar palsy, regardless of disease duration, were eligible for screening. Participants were randomised (1:1:1) to receive oral trazodone 200 mg once a day, oral memantine 20 mg once a day, or matched placebo using a computer-generated minimisation algorithm delivered via a secure web-based system. Co-primary outcome measures were clinical functioning, measured by rate of change in the Amyotrophic Lateral Sclerosis Functional Rating Scale Revised (ALSFRS-R), and survival. Comparisons were conducted in four stages, with predefined criteria for stopping at the end of stages one and two. We report interim analysis from the stage two results, which was done when 100 participants per group (excluding long survivors, defined as >8 years since diagnosis at baseline) completed a minimum of 12 months of follow-up for the candidate investigational medicinal products. The trial is registered on the European Clinical Trials Registry, 2019-000099-41, and ClinicalTrials.gov, NCT04302870, and is ongoing. Between Feb 27, 2020, and July 24, 2023 (database lock for interim analysis two), 554 people with a motor neuron disease were randomly allocated to memantine (183 [33%]), trazodone (185 [33%]), or placebo (186 [34%]). The primary interim analysis population comprised 530 participants, of whom 175 (33%) had been allocated memantine, 175 (33%) had been allocated trazodone, and 180 (34%) had been allocated placebo. Over 12 months of follow-up, the mean rate of change per month in ALSFRS-R was -0\u00b7650 for memantine, -0\u00b7625 for trazodone, and -0\u00b7655 for placebo (memantine versus placebo estimated mean difference 0\u00b7033, one-sided 90% CI lower level -0\u00b7085; one-sided p=0\u00b736; trazodone vs placebo: 0\u00b7065, -0\u00b7051; one-sided p=0\u00b724). The one-sided p values were both above the significance threshold of 10%, indicating that neither memantine nor trazodone groups met the criteria for continuation. There were 483 participants with at least one adverse event (145 [77%] on placebo, 170 [91%] on memantine, and 168 [90%] on trazodone). There were 88 participants with at least one serious adverse event (37 [20%] on memantine, 27 [14%] on trazodone, and 24 [13%] on placebo). A total of 11 serious adverse event led to treatment discontinuation. There was no survival difference between comparisons, with 49 deaths in the memantine group, 52 deaths in the trazodone group, and 48 deaths in the placebo group. Neither memantine nor trazodone improved efficacy outcomes compared with placebo. This result is sufficiently powered to warrant no further testing of trazodone or memantine in motor neuron disease at the doses evaluated in this study. The multiarm multistage design shows important benefits in reducing the time, cost, and participant numbers to reach a definitive result.

We evaluate the outcome of GBS patients with bulbar palsy, and also compare the risks and benefits of intubation and MV in them. 187 GBS patients with bulbar palsy from a cohort of 547 GBS registry were analyzed. Detailed clinical records and peak disability on a 0-6 GBS Disability Scale (GBSDS) were noted. The patients were intubated if arterial blood gas (ABG) analysis revealed hypoxia, hypercarbia or acidosis. The patients with normal ABG parameters were fed by nasogastric tube, and nursed in lateral position. Occurrence of pneumonia, in-hospital death and outcomes at 6-months were classified as complete (GBSDS <2), partial (GBSDS 2-3) and poor (GBSDS >3). 76/187(40.6%) patients required MV, and they had a shorter duration of illness (p = 0.007), higher peak disability (p < 0.001), autonomic dysfunction (p < 0.001) and more frequently received IVIg (p = 0.02). Pneumonia (63% vs 10.8%; p < 0.001) and in-hospital deaths (7.9% vs 1.8%; p = 0.06) were more frequent in MV group compared to nasogastric fed group. At 6-months,104 (55.6%) patients recovered completely. On multivariate analysis, the independent predictors of poor outcome were peak disability [Adjusted Odds Ratio (AOR) 9.84, 95% Confidence Interval (CI) 3.15-30.74, p < 0.0001], day of hospitalization from disease onset (AOR 1.09, 95% Cl 1.01-1.01; p=0.009) and requirement of MV (AOR 0.10; 95% 0.02-0.50; p = 0.005). GBS patients with bulbar palsy may be managed by nasogastric feeding and nursing in lateral position without increasing the risk of pneumonia. Mechanical ventilation based on ABG does not worsen outcomes of GBS with bulbar palsy.\n\nID: 38984697\nTitle: Autonomic Dysfunction in Amyotrophic Lateral Sclerosis - A Case-Control Study.\nAbstract: This study aimed to explore autonomic nervous system involvement in amyotrophic lateral sclerosis (ALS) patients by evaluating sympathetic skin response (SSR). The study included 35 sporadic (ALS) patients (cases), and 35 healthy age and sex-matched participants (controls) aged <60 years. SSR was recorded in the electrophysiology lab of the Neurology Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Patients with diseases associated with peripheral or autonomic neuropathy were excluded. Prolonged latency (delayed SSR) or an absent response was considered abnormal SSR. SSR was found to be abnormal in 17 (48.6 %) ALS cases, with an absent response in the upper limbs of six cases (17.1%). Abnormal SSR was more prevalent in the lower limbs, with 33 (94.3%) and 20 (57.1%) cases having a delayed or absent response, respectively. In comparison, SSR was normal in all control participants (P-value <0.05). Abnormal SSR was significantly more common in the lower limbs of ALS cases with bulbar palsy than those without bulbar palsy (P-value=0.04). There was no association of SSR with disease severity and duration. ALS is significantly associated with abnormal SSR, indicating autonomic nervous system involvement. There could also be an association between bulbar palsy and abnormal SSR among ALS patients. Further studies should be carried out to determine the association of abnormal SSR with disease severity, duration, and type.\n\nID: 38741489\nTitle: [Fisher Syndrome].\nAbstract: Fisher syndrome is recognized as a variant of Guillain-Barr\u00e9 syndrome, encompassing acute onset immune-mediated neuropathies marked by the classical triad of ataxia, areflexia, and ophthalmoplegia. Generally, Fisher syndrome follows a self-limited course with a good prognosis. Ophthalmoplegia, typically bilateral, progresses to complete external ophthalmoplegia within 1-2 weeks. Ataxia, often very severe, may cause an inability to walk without support despite normal strength. Fisher syndrome is also frequently concomitant with additional clinical features, including ptosis, internal ophthalmoplegia, facial nerve palsy, sensory deficits, and bulbar palsy. The confirmation of an antecedent infection is often established. Among the ganglioside antibodies, anti-GQ1b antibodies exhibit positivity in over 80% of patients. The syndrome manifests in three distinct types: a partial subtype exhibiting only a subset of the triad symptoms, Bickerstaff's brainstem encephalitis marked by impaired consciousness and pyramidal tract signs, and an overlapping subtype with Guillain-Barr\u00e9 syndrome, characterized by weakness in the extremities.\n\nID: 38536565\nTitle: AI-assisted automatic MRI-based tongue volume evaluation in motor neuron disease (MND).\nAbstract: Motor neuron disease (MND) causes damage to the upper and lower motor neurons including the motor cranial nerves, the latter resulting in bulbar involvement with atrophy of the tongue muscle. To measure tongue atrophy, an operator independent automatic segmentation of the tongue is crucial. The aim of this study was to apply convolutional neural network (CNN) to MRI data in order to determine the volume of the tongue. A single triplanar CNN of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head. The 3D volumes were processed slice-wise across the three orientations and the predictions were merged using different voting strategies. This approach was developed using MRI datasets from 20 patients with 'classical' spinal amyotrophic lateral sclerosis (ALS) and 20 healthy controls and, in a pilot study, applied to the tongue volume quantification to 19 controls and 19 ALS patients with the variant progressive bulbar palsy (PBP). Consensus models with softmax averaging and majority voting achieved highest segmentation accuracy and outperformed predictions on single orientations and consensus models with union and unanimous voting. At the group level, reduction in tongue volume was not observed in classical spinal ALS, but was significant in the PBP group, as compared to controls. Utilizing single U-Net trained on three orthogonal orientations with consequent merging of respective orientations in an optimized consensus model reduces the number of erroneous detections and improves the segmentation of the tongue. The CNN-based automatic segmentation allows for accurate quantification of the tongue volumes in all subjects. The application to the ALS variant PBP showed significant reduction of the tongue volume in these patients and opens the way for unbiased future longitudinal studies in diseases affecting tongue volume.\n\nID: 41820266\nTitle: An Unusual Presentation of Juvenile Amyotrophic Lateral Sclerosis with Superoxide Dismutase 1 Mutation: Subacute Bulbar Palsy With Asymmetric Limb Weakness.\nAbstract: \n\nID: 41517538\nTitle: Establishing Diagnostic and Differential Diagnostic Criteria for Amyotrophic Lateral Sclerosis.\nAbstract: Motor neuron disease (MND) represents a broad and heterogeneous group of disorders involving the upper or lower motor neurons, represented mainly by amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), progressive muscular atrophy (PMA) and progressive bulbar palsy (PBP). Primary motor neuronopathies are characterized by progressive degenerative loss of anterior horn cell motoneurons (lower motor neurons) or loss of giant pyramidal Betz cells (upper motor neurons). Rare atypical variants of MND-ALS include flail arm syndrome (FA), flail leg syndrome (FL), facial-onset sensory and motor neuronopathy (FOSMN), finger extension weakness and downbeat nystagmus motor neuron disease (FEWDON-MND) and long-standing and juvenile MND-ALS. In this article, we present a review of diagnostic criteria and the differential diagnosis for MND, focusing on ALS.\n\nID: 40913874\nTitle: A case report on Ayurvedic management of progressive bulbar palsy-A rare amyotrophic lateral sclerosis phenotype.\nAbstract: This case report is the description of a devastating illness, Progressive Bulbar Palsy (PBP) of a sixty-seven years old male patient. He presented with complaints of slurred speech, hearing impairment, generalised weakness of limbs, weakened grip to hold objects in hand, difficulty to walk with normal speed, frequent dizzy feeling while walking, severe fatigue, increased anger, heaviness of head, depression, anxiety, decreased memory and headache for 1 year. When he consulted conventional medicine, in Magnetic Resonance Imaging (MRI) of brain, only 'Partial empty sella' and age related mild cerebral atrophy was detected and the patient was diagnosed PBP clinically. They prescribed Riluzole 50 mg tablet twice a day and Fluoxetine 10mg capsules at night time for 3 months, but obtained no relief for symptoms and consulted this Out Patient Department (OPD). In Ayurvedic parlance, PBP resembles conditions like Kaphavruta vata. In this patient, Pittavritavata symptoms like bhrama (\u223cdizziness) was also present in increased severity. Diagnosis was done with the aid of Gold Coast diagnostic criteria. Internal and external medications with properties alleviating avarana (\u223cocclusion) of vata by kapha and pitta, shodhana (\u223cexpelling the aggravated doshas and cleanses the body internally), rejuvenating (Rasayana) properties, for overall strengthening of nervous system and musculoskeletal system, enhancing balance and coordination, improving speech and memory were used. The assessment was done before and after the treatment by 'Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). The score before and after the treatment was 35 and 45 respectively out of 48. The treatment helped to increase the quality of life exceptionally as symptomatic relief was obtained. As it is a devastating disorder with poor prognosis and most probably will lead to death, it is advisable to repeat the treatments in regular intervals, depending on the recurrence of symptoms, if any.\n\nID: 40901171\nTitle: Acquired hemophilia a in a female with minimal change disease and hypothyroidism: a rare case report.\nAbstract: Juvenile amyotrophic lateral sclerosis (J-ALS) is extremely rare neurodegenerative motor neuron disorder that begins in early childhood or adolescence, before the age of 25\u00a0years old. It is characterized by gradual disease progression with comparison to adult-onset ALS and is often linked to genetic mutations. A 16-years-old female presented with long history of generalized weakness since age of 10 years, followed by bilateral sensorineural hearing loss, bulbar symptoms, and limb spasticity. Neurological examination revealed upper motor neuron signs in upper limbs, lower motor neuron signs in lower limbs, and bulbar involvement. Nerve conduction test was normal however, MRI showed early degenerative changes, and diagnosed with J-ALS after careful evaluation. She was started on Riluzole. Despite ICU care and supportive interventions including PEG and tracheostomy, she succumbed to respiratory failure. Rarity, atypical presentation, and finical constraints can delay diagnosis of J-ALS. However, early diagnosis after careful evaluation of clinical symptoms, medical history, electrophysiological and imaging studies followed by prompt treatment with Riluzole and supportive interventions can help prolong survival and improve quality of life. J-ALS is a rare motor neuron disease which possess immense diagnostic challenges, can exhibit relentless progression over short period of time with time.\n\nID: 40364643\nTitle: Latest progress and challenges in drug development for degenerative motor neuron diseases.\nAbstract: Motor neuron diseases are sporadic or inherited fatal neurodegenerative conditions. They selectively affect the upper and/or lower motor neurons in the brain and spinal cord and feature a slow onset and a subacute course contingent upon the site of damage. The main types include amyotrophic lateral sclerosis, progressive muscular atrophy, primary lateral sclerosis, and progressive bulbar palsy, the pathological processes of which are largely identical, with the main disparity lying in the location of the lesions. Amyotrophic lateral sclerosis is the representative condition in this group of diseases, while other types are its variants. Hence, this article mainly focuses on the advancements and challenges in drug research for amyotrophic lateral sclerosis but also briefly addresses several other important degenerative motor neuron diseases. Although the precise pathogenesis remains elusive, recent advancements have shed light on various theories, including gene mutation, excitatory amino acid toxicity, autoimmunology, and neurotrophic factors. The US Food and Drug Administration has approved four drugs for use in delaying the progression of amyotrophic lateral sclerosis: riluzole, edaravone, AMX0035, and tofersen, with the latter being the most recent to receive approval. However, following several phase III trials that failed to yield favorable outcomes, AMX0035 has been voluntarily withdrawn from both the US and Canadian markets. This article presents a comprehensive summary of drug trials primarily completed between January 1, 2023, and June 30, 2024, based on data sourced from clinicaltrials.gov. Among these trials, five are currently in phase I, seventeen are in phase II, and eleven are undergoing phase III evaluation. Notably, 24 clinical trials are now investigating potential disease-modifying therapy drugs, accounting for the majority of the drugs included in this review. Some promising drugs being investigated in preclinical studies, such as ATH-1105, are included in our analysis, and another review in frontiers in gene therapy and immunotherapy has demonstrated their therapeutic potential for motor neuron diseases. This article was written to be an overview of research trends and treatment prospects related to motor neuron disease drugs, with the aim of highlighting the latest potentialities for clinical therapy.\n\nID: 40273615\nTitle: Electrodiagnostic characteristics of neuromuscular disease in paediatric intensive care.\nAbstract: Assessing peripheral electrodiagnostic (EDX) tests in paediatric intensive care. Data from patients who had undergone EDX test/s between 2010 and 2019 at a tertiary centre were retrospectively analysed, including final neuromuscular diagnoses, EDX results and demographic information. EDX data included motor and sensory nerve conduction study, needle electromyography (EMG), repetitive nerve stimulation and stimulated single fiber EMG. Final clinical diagnosis was based on several investigations including muscle biopsy, MR imaging, gene testing, EDX-tests and clinical phenotype. 351 patients were identified (56\u00a0% male, average age 42.5\u00a0months), with diagnoses categorised into the following groups: no identifiable neuromuscular disorders (45\u00a0%), neuropathy (13\u00a0%), motor neuron disease (9\u00a0%), isolated bulbar palsy (6\u00a0%), myopathy (14\u00a0%), neuromuscular junction disorders (5\u00a0%), and critical illness neuromyopathy (8\u00a0%). EDX data was stratified into 7 electrodiagnostic categories: normal, neuropathy, motor neuron disease, isolated bulbar palsy, myopathy, neuromuscular junction disorders, and critical illness neuromyopathy. With this stratification we were able to predict the final diagnosis with acceptable accuracy. The prevalence of neuromuscular disease groups in paediatric ICU was defined together with their corresponding EDX characteristics. The study confirms the utility of electrophysiology as a valuable tool for diagnosing and managing neuromuscular conditions in paediatric ICU.\n\nID: 39360074\nTitle: Exploring the Impact of Personalized Physical Therapy on a Patient With Motor Neuron Disorder: A Case Study.\nAbstract: This case study examines the effect of a tailor-made physiotherapy regimen on an 85-year-old male patient who was suffering from bulbar motor neuron disease (MND) and had a history of stroke and COVID-19. The physiotherapy plan was designed to strategically address the patient's respiratory issues, generalized weakness affecting limb muscles, and speech and swallowing difficulties. Frequent evaluations made it possible to adjust the treatment plan, emphasizing a holistic strategy to improve the patient's overall quality of life. Improvements in scores on multiple functional scales and manual muscle testing were shown by outcome measures and follow-up evaluations. This case emphasizes how important customized physiotherapy is for maximizing functional outcomes and enhancing the quality of life for patients dealing with the complicated conditions of bulbar MND.\n\nID: 38797685\nTitle: [Juvenile-onset anti-nuclear matrix protein 2 (NXP-2) antibody-positive dermatomyositis with joint contractures before manifestation of myositis: a case report].\nAbstract: A 23-year-old man was admitted to our hospital with a one-year history of muscle weakness and atrophy. He had noticed contractures of the fingers of both hands from the age of 18. Examination revealed a skin rash including heliotrope rash and Gottron's sign, joint contractures in the extremities, dysphagia, extensive muscle weakness and marked muscle atrophy. The serum creatine kinase level was 272\u2005\u200dIU/l and muscle biopsy showed typical perifascicular atrophy but little lymphocyte invasion. There was no interstitial pneumonia or malignancy, but muscle tendons showed elevated CT values suggesting calcification or fibrosis. Anti-nuclear matrix protein 2 (NXP-2) antibody-positive dermatomyositis was diagnosed on the basis of the serum antibody level. Methylprednisolone pulse therapy ameliorated the skin rash and bulbar palsy, but muscle weakness, atrophy and joint contractures were resistant to the treatment. There have been no previous reports of young adults with anti-NXP-2 antibody-positive dermatomyositis in whom joint contracture became evident as early as 4 years beforehand, which is a important feature for differential diagnosis of dermatomyositis.\n\nID: 38522911\nTitle: The clinical practice guideline for the management of amyotrophic lateral sclerosis in Japan-update 2023.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an adult-onset intractable motor neuron disease characterized by selective degeneration of cortical neurons in the frontotemporal lobe and motor neurons in the brainstem and spinal cord. Impairment of these neural networks causes progressive muscle atrophy and weakness that spreads throughout the body, resulting in life-threatening bulbar palsy and respiratory muscle paralysis. However, no therapeutic strategy has yet been established to halt ALS progression. Although evidence for clinical practice in ALS remains insufficient, novel research findings have steadily accumulated in recent years. To provide updated evidence-based or expert consensus recommendations for the diagnosis and management of ALS, the ALS Clinical Practice Guideline Development Committee, approved by the Japanese Society of Neurology, revised and published the Japanese clinical practice guidelines for the management of ALS in 2023. In this guideline, disease-modifying therapies that have accumulated evidence from randomized controlled trials were defined as \"Clinical Questions,\" in which the level of evidence was determined by systematic reviews. In contrast, \"Questions and Answers\" were defined as issues of clinically important but insufficient evidence, according to reports of a small number of cases, observational studies, and expert opinions. Based on a literature search performed in February 2022, recommendations were reached by consensus, determined by an independent panel, reviewed by external reviewers, and submitted for public comments by Japanese Society of Neurology members before publication. In this article, we summarize the revised Japanese guidelines for ALS, highlighting the regional and cultural diversity of care processes and decision-making. The guidelines cover a broad range of essential topics such as etiology, diagnostic criteria, disease monitoring and treatments, management of symptoms, respiration, rehabilitation, nutrition, metabolism, patient instructions, and various types of care support. We believe that this summary will help improve the daily clinical practice for individuals living with ALS and their caregivers.\n\n\n\n\n\nID: 40957031\nTitle: Intrathecal Baclofen to Improve Functional Status in ALS: A Case Report.\nAbstract: Intrathecal pumps are well known to benefit patients with chronic pain as well as spasticity. Intrathecal baclofen (ITB) can offer doses 100-1000 times smaller with similar efficacy, compared to oral baclofen. Only 2 previous reports detailed improvement in functional status after patients with amyotrophic lateral sclerosis (ALS) received ITB. Our patient presented with progressive bulbar palsy, further progressing to ALS. His lower extremity spasticity and tremors continued to progress over 3 years despite increased baclofen. At the time of implant, he expressed whole body tremors and spasticity to bilateral lower extremities, complicated by falls. Prior to the trial, the patient ambulated 50 feet. ITB was started at a rate of 100 mcg/day. After the implant, the patient's ambulation distance increased to 100 feet. The patient and his wife reported resolution of his tremors and improvement in spasticity. This report details the functional improvement obtained from ITB in a patient with ALS.\n\nID: 37295193\nTitle: Gender differences in clinical features at the initial examination of late-onset amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that mainly affects motor neurons in the brain and spinal cord. With the advent of aging societies, the proportion of elderly patients with ALS is expected to increase. We retrospectively compared the clinical characteristics at the initial examination of patients with onset of ALS at age 74\u00a0years or younger (early onset) and those aged 75\u00a0years or older at onset (late-onset) at a single regional ALS diagnostic center in Japan. The phenotype of late-onset ALS differed between males and females, with late-onset females having more bulbar-onset ALS and significantly lower body mass index, late-onset males having more frequent bulbar and respiratory symptoms at the initial examination, and significantly lower forced vital capacity at the initial examination in both groups compared to early onset patients. For late-onset patients, maintenance of skeletal muscle mass by early intervention for bulbar and respiratory symptoms may be useful for prolonging survival; however, a prospective analysis is warranted.\n\n\n\nID: 38511308\nTitle: Effect of Intermittent Oro-Esophageal Tube Feeding in Bulbar Palsy After Ischemic Stroke: A Randomized Controlled Study.\nAbstract: Nasogastric tube feeding (NG) has been widely used in patients with bulbar palsy after ischemic stroke but is associated with a significant risk of complications including malnutrition and pneumonia. Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke. This randomized controlled study included 148 patients with bulbar palsy after ischemic stroke who underwent routine treatment and swallowing rehabilitation training in the Department of Rehabilitation Medicine between July 2017 and July 2019 in China. The participants were randomly divided into the IOE group (n=74) and NG group (n=74) with IOE and NG as nutritional supports, respectively. The primary outcome was nutritional status including (1) body mass index (kg/m2), (2) serum ALB (albumin, g/L), and (3) PA (prealbumin, mg/L). The secondary outcomes were (1) swallowing function including (i) Functional Oral Intake Scale (FOIS) and (ii) Penetration-Aspiration Scale, (2) pneumonia, (3) depression, and (4) adverse events. Statistical analyses for continuous outcomes were performed using t test, Mann-Whitney U test and Wilcoxon signed-rank test and categorical variables using \u03c72 test. SPSS 21.0 was used for all analysis. There were no significant baseline differences between the 2 groups. After the treatment, the IOE group demonstrated significantly better results compared with the NG group in ALB ([32.71\u00b10.94] versus [32.28\u00b10.81] g/L; P=0.003), PA ([278.15\u00b113.81] versus [270.31\u00b115.08] mg/L; P=0.001], body mass index ([19.77\u00b11.03] versus [19.41\u00b10.98] kg/m2; P=0.002], FOIS (P<0.001), Penetration-Aspiration Scale (P<0.001), stroke-associated pneumonia ([1, 4.05%] versus [26, 35.14%]; P<0.001), depression ([1, 1.35%] versus [44, 59.46%]; P<0.001) and overall less adverse events (reflux, fever, discomfort in the throat; P<0.001). In patients with dysphagia with bulbar palsy after ischemic stroke who received routine treatment and swallowing rehabilitation training, IOE is safer and more conducive to the improvement of nutritional status, swallowing function, stroke-associated pneumonia, and depression than NG.

However, most research has focused on its later stages rather than its earlier stages, including the prognosis of patients with this condition, or factors that act as early predictors of risk. Therefore, our study aimed to identify early predictors of respiratory muscle paralysis in patients with GBS and determine the short-term prognosis of such patients. We recruited 455 GBS patients (age \u2265 18) who had been hospitalized in the First Affiliated Hospital of Harbin Medical University between 2016 and 2021, retrospectively. We recorded clinical and laboratory data and used linear and logistic regression analysis to investigate the relationship between early clinical, examination results, and subsequent respiratory muscle paralysis. Among the 455 patients, 129 were assigned to a respiratory muscle paralysis group and 326 were assigned to a non-respiratory muscle paralysis group. Compared with the non-affected group, the time from onset to admission was shorter (p = 0.0003), and the Medical Research Council (MRC) score at admission and discharge was smaller in the affected group (p < 0.0001). Compared with the non-affected group, the affected group had higher Hughes and Erasmus GBS Respiratory Insufficiency Score (EGRIS) scores at admission and longer hospital stays (p < 0.0001). Patients in the affected group were more likely to have bulbar palsy and lung infections (p < 0.0001). To conclude, bulbar palsy, a higher EGRIS score and Hughes score at admission, a lower MRC score, and a shorter time between onset and admission, are all predictive risk factors for respiratory muscle paralysis in patients with GBS. An increase in any of these factors increases the risk of muscle paralysis. Patients with respiratory muscle paralysis have a poorer short-term prognosis than those without respiratory muscle paralysis. Therefore, we should attempt to identify patients with one or more of these characteristics in the early stages of admission, provide ventilation management, and administer IMV treatment if necessary.\n\nID: 36428088\nTitle: Modified Erasmus GBS Respiratory Insufficiency Score: a simplified clinical tool to predict the risk of mechanical ventilation in Guillain-Barr\u00e9 syndrome.\nAbstract: This study aimed to determine the clinical and diagnostic factors associated with mechanical ventilation (MV) in Guillain-Barr\u00e9 syndrome (GBS) and to simplify the existing Erasmus GBS Respiratory Insufficiency Score (EGRIS) for predicting the risk of MV. Data from the first 1500 patients included in the prospective International GBS Outcome Study (IGOS) were used. Patients were included across five continents. Patients <6 years and patients from Bangladesh were excluded. Univariable logistic and multivariable Cox regression were used to determine which prespecified clinical and diagnostic characteristics were associated with MV and to predict the risk of MV at multiple time points during disease course. 1133 (76%) patients met the study criteria. Independent predictors of MV were a shorter time from onset of weakness until admission, the presence of bulbar palsy and weakness of neck flexion and hip flexion. The modified EGRIS (mEGRIS) was based on these factors and accurately predicts the risk of MV with an area under the curve (AUC) of 0.84 (0.80-0.88). We internally validated the model within the full IGOS cohort and within separate regional subgroups, which showed AUC values of 0.83 (0.81-0.88) and 0.85 (0.72-0.98), respectively. The mEGRIS is a simple and accurate tool for predicting the risk of MV in GBS. Compared with the original model, the mEGRIS requires less information for predictions with equal accuracy, can be used to predict MV at multiple time points and is also applicable in less severely affected patients and GBS variants. Model performance was consistent across different regions.\n\nID: 36081331\nTitle: A 44-Year-Old Alcohol-Dependent Man Who Recovered from Central Pontine Myelinolysis with Supportive Physical Therapy.\nAbstract: BACKGROUND Central pontine myelinolysis (CPM) includes symmetric demyelination of the central pons. CPM is a rare neurological disorder that generally develops after rapid correction of hyponatremia in individuals having underlying conditions, such as malnutrition, alcoholism, and severe burns. It can cause severe long-term disabilities. However, there is currently no pharmacotherapy capable of promoting remyelination, a process crucial for recovery from CPM. We present the case of a patient with alcoholism and malnutrition-related CPM, which developed following rapid correction of hyponatremia but then improved remarkably with supportive physical therapy. CASE REPORT A 44-year-old alcoholic and malnourished man was admitted to an emergency hospital for disorientation due to overdrinking, but later developed bulbar palsy after hyponatremia was unexpectedly, but rapidly, corrected. Axial scans of the diffusion-weighted brain MRI revealed a characteristic lesion known as a piglet sign in the central pons. Based on his underlying conditions, present episode of sodium correction, and MRI finding, the patient was diagnosed as having CPM, which progressively worsened, resulting in locked-in syndrome after 12 days. The patient was then transferred to a long-term care unit and received simple motion exercise daily, but no specific medication. His symptoms gradually improved, achieving discontinuation of tube feeding on day 21, independent walking on day 110, and discharge after 6 months. CONCLUSIONS This report highlights the importance of physical therapy, the potential of which is often underestimated despite its broad benefits for human health, as a readily applicable intervention for patients with CPM. Further understanding of mechanisms underlying exercise-induced myelination should contribute to establishing novel therapies for a wide spectrum of brain disorders.\n\nID: 35186497\nTitle: Clinical predictors and electrodiagnostic characteristics in patients with Guillain-Barr\u00e9 syndrome with respiratory failure: a retrospective, matched case-control study.\nAbstract: Respiratory failure is a common complication of Guillain-Barr\u00e9 syndrome (GBS). This study aimed to determine the clinical predictors and electrodiagnostic (EDx) characteristics in patients with Guillain-Barr\u00e9 syndrome (GBS) with respiratory failure. The retrospective study included 29 confirmed GBS cases with respiratory failure and age- (\u00b15 years) and sex-matched controls (1:1). The dependent t-test and McNemar-Bowker test were used to analyse the continuous and categorical data, respectively. In addition, a multiple logistic regression analysis was used to analyse the predictive factors for respiratory failure. Among both cases and controls, the majority were male (72.4%), and the average age was 50.9 years. The data showed that patients with respiratory failure had higher GBS disability scores, lower motor power (\u22643) of the hip flexors and ankle dorsiflexors, and experienced facial and bulbar palsy. In the multivariate analysis, the significant predictive factors were bulbar palsy (AOR 10.4 [95% CI [2.6-41.4]) and motor power of hip flexors \u2264 3 (AOR 31.4 [95% CI [3.1-314.5]). Patients with respiratory failure had lower compound muscle action potential amplitude of the ulnar and tibial nerves. The median, ulnar, and tibial nerve conduction studies were more likely to reflect inexcitability. The GBS subtypes in GBS patients with and without respiratory failure were not significantly different. Bulbar palsy and motor power of the hip flexors \u2264 3 were significant predictors for respiratory failure. The GBS subtypes in patients with and without respiratory failure were not significantly different.\n\nID: 32889770\nTitle: Changes in serum complements and their regulators in generalized myasthenia gravis.\nAbstract: To investigate changes in serum complements and their regulators in the pathogenesis of myasthenia gravis (MG). Forty-four patients with acetylcholine receptor antibody-positive MG, as well as 20 patients with non-inflammatory neurological disorders were enrolled. Serum complements (C3, C4 and soluble C5b-9) and complement regulators (vitronectin, clusterin and properdin) were extensively analysed by enzyme-linked immunosorbent assay and their associations with clinical profiles of MG were examined. Serum C3, C4 and clusterin levels were not significantly different between patients with MG and controls. The patients with MG had higher soluble C5b-9 (P\u00a0=\u00a00.09) and vitronectin (P\u00a0=\u00a00.001) levels than the controls; moreover, vitronectin levels decreased after treatment (P\u00a0=\u00a00.09). Serum properdin (P\u00a0=\u00a00.03) levels were lower in the patients with MG than in the controls, and negatively correlated with the MG Activities of Daily Living score (rs\u00a0=\u00a0-0.26, P\u00a0=\u00a00.09) and with the presence of bulbar palsy (P\u00a0=\u00a00.04). Our results show that activation of complements and an altered complement network could contribute to the inflammatory pathogenesis of MG.\n\nID: 29225249\nTitle: Acute Tetraparesis with Respiratory Failure after Steroid Administration in a Patient with a Dural Arteriovenous Fistula at the Craniocervical Junction.\nAbstract: A 63-year-old man developed vomiting, paraparesis, dysuria, bulbar palsy, and orthostatic hypotension over a period of 5 months. Neuroradiological examinations showed a swollen lower brainstem with a dural arteriovenous fistula at the craniocervical junction (DAVF-CCJ). A steroid was administered intravenously in the hospital to relieve brainstem edema. A few hours later, however, the patient developed acute tetraparesis with respiratory failure. Recently, there have been several reports describing the acute worsening of paraparesis in patients with a spinal dural arteriovenous fistula after steroid treatment. In addition to these reports, the present case suggests the risk of administering steroids to patients with DAVF-CCJ, especially those with brainstem dysfunction.\n\nID: 26844510\nTitle: A Case Report of Locked-in Syndrome Due to Bilateral Vertebral Artery Dissection After Cervical Spine Manipulation Treated by Arterial Embolectomy.\nAbstract: Cervical spine manipulation (CSM) is a commonly spinal manipulative therapies for the relief of cervical spine-related conditions worldwide, but its use remains controversial. CSM may carry the potential for serious neurovascular complications, primarily due to vertebral artery dissection (VAD) and subsequent vertebrobasilar stroke. Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy.A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour. Gradually, although the patient remained conscious, he could not speak but could communicate with the surrounding by blinking or moving his eyes, and turned to complete quadriplegia, complete facial and bulbar palsy, dyspnea at 4\u200ahours after admission. He was diagnosed with LIS. Then, the patient was received cervical and brain computed tomography angiography that showed bilateral VAD. Aortocranial digital subtraction angiography showed vertebrobasilar thrombosis, blocking left vertebral artery, and stenosis of right vertebral artery. The patient was treated by using emergency arterial embolectomy and followed by antiplatelet therapy and supportive therapy in the intensive care unit and a general ward. Twenty-seven days later, the patient's physical function gradually improved and discharged but still left neurological deficit with muscle strength grade 3/5 and hyperreflexia of limbs.Our findings suggested that CSM might have potential severe side-effect like LIS due to bilaterial VAD, and arterial embolectomy is an important treatment choice. The practitioner must be aware of this complication and should give the patients informed consent to CSM, although not all stroke cases temporally related to SCM have pre-existing craniocervical artery dissection.\n\nID: 26065427\nTitle: West Nile Meningoencephalitis Presenting as Isolated Bulbar Palsy With Hypercapnic Respiratory Failure: Case Report and Literature Review.\nAbstract: Since the outbreak of West Nile virus (WNV) in the United States in 1999, the WNV neuroinvasive disease has been increasingly reported with a wide spectrum of neuromuscular manifestations. We submit a case of a 46-year-old male with a history of alcohol abuse, diabetes, hypertension, and hepatitis C who presented with fever, nausea, shortness of breath, and dysphagia. The patient rapidly developed hypercapnic respiratory failure and was found to have WNV meningoencephalitis without obvious neuromuscular weakness. His hospital course was significant for repeated failures of extubation secondary to persistent bulbar weakness eventually requiring tracheotomy. This is a unique case of WNV meningoencephalitis with bulbar palsy without other neuromuscular manifestations resulting in recurrent hypercapnic respiratory failure.\n\nID: 22019655\nTitle: Prognosis of patients with Guillain-Barr\u00e9 syndrome requiring mechanical ventilation.\nAbstract: Severe Guillain-Barr\u00e9 syndrome (GBS) is associated with significant morbidity and also mortality. Identification of modifiable risk factors may help in reducing the morbidity and mortality. To study the prognostic factors in a selected cohort of mechanically ventilated GBS patients. Case records of GBS patients requiring mechanical ventilation admitted between 1997 and 2007 were analyzed. All patients satisfied the National Institute of Neurological and Communicative Disorders and Stroke (NINCDS) criteria for GBS. Primary outcome parameters included mortality and GBS disability (Hughes) scale score at discharge. During the study period, 173 (118 men and 55 women; mean age of 33.5 \u00b1 21 years) GBS patients were mechanically ventilated. A history of antecedent events was present in 83 (48%) patients. In addition to motor weakness, In all facial palsy was present in 106 (61%), bulbar palsy in 91 (53%), sensory involvement in 74 (43%), and symptomatic autonomic dysfunction in 27 (16%). The overall mortality was 10.4%. On univariate analysis the risk factors for mortality included elderly age (P = 0.014), autonomic dysfunction (P = 0.002), pulmonary complications (P = 0.011), hypokalemia (P = 0.011), and bleeding (P = 0.026). All these factors were significant in multivariate analysis except for bleeding from any site and hypokalemia. In univariate analysis factors associated with Hughes scale score \u2264 3 at discharge included younger age (P = 0.02), presence of bulbar symptoms (P = 0.03) and less severe weakness at admission (P = 0.02), slower evolution of disease over more than 3 days (P = 0.01), electrodiagnostic evidence of demyelinating neuropathy (P = 0.00), and absence of sepsis (P = 0.01), hyperkalemia (P = 0.0001), and anemia (P = 0.02). In multivariate analysis age was the only significant factor. Early identification of modifiable risk factors, such as pulmonary involvement, autonomic dysfunction, hypokalemia, sepsis, bleeding, and nutritional complications, may reduce the mortality and morbidity associated with GBS.\n\nID: 18317983\nTitle: [Treatment of sialorrhea in patients under long-term ventilation].\nAbstract: Sialorrhea (drooling or excessive salivation) is a common problem in patients with progressive neurolomuscular diseases and bulbar palsy. Contributing factors are hypersecretion of saliva induced by cholinergic drugs and poor dental status. Non-invasive ventilation is often severely impaired in these patients. Treatment should be initiated with a thorough evaluation of the medication and of the oral status by an otorhinolaryngologist. As drooling is commonly caused by poor oral or pharyngeal neuromuscular control, swallowing therapy should be initiated by a speech therapist. Further treatment options are anticholinergic medications, botulinum toxin injections into the salivary gland, radiation and and surgical procedures. Whereas systemic anticholinergic medications lead often to side effects, the (ultrasound-guided) injection of botulinum toxin into the parotid and submandibular gland is a safe and effective method for controlling drooling for at least 2 months.\n\nID: 18029029\nTitle: Upper aerodigestive tract sequelae in severe enterovirus 71 infection: predictors and outcome.\nAbstract: Enterovirus 71 (EV71) infection sequelae can be severe and life-threatening, and long-term follow-up outcomes remain unknown. Therefore, we conducted a retrospective follow-up study to review airway and neurological sequelae development in patients with severe EV71 infection. We also studied the incidence and risk factors for tracheotomy and gastrostomy requirement. We investigated 202 EV71-infected children according to their disease stage. Seventy-two of them were diagnosed to have EV71 encephalitis, which was characterized by myoclonus, ataxia, nystagmus, oculomotor palsy and bulbar palsy or combinations of these conditions. All the 72 patients required endotracheal intubation due to respiratory failure or ventilator dependence; among these, 14 underwent tracheostomy and 10 underwent gastrostomy. All patients were followed-up for at least 3 years after discharge. Predictors of tracheostomy and gastrostomy requirement were age <2 years, body weight <10th percentile, pulmonary hemorrhage or edema, meningeal symptoms and magnetic resonance imaging (MRI) findings of upper spinal cord and brainstem. We determined outcome based on persistent tracheostomy or gastrostomy requirement and whether patients developed positive neurological sequelae. Significant tracheostomy and gastrostomy predictors were age <2 years, pulmonary edema or hemorrhage, hypotension, hemiparesis and positive MRI findings. Statistical analysis revealed pulmonary edema and hypotension as index predictors of tracheostomy requirement and pulmonary edema as the significant risk factor for gastrostomy. Long-term neuropsychological impact was observed on children who present the signs of the pulmonary edema or hypotension in the early onset of the EV71 infection. EV71-infected patients who develop neurological pulmonary edema or hypotension should be hemodynamically stabilized and undergo early tracheostomy to prevent further complications. This may improve the decannulation success rate after the brainstem function recovers.\n\nID: 17611489\nTitle: Antibodies to AChR, MuSK and VGKC in a patient with myasthenia gravis and Morvan's syndrome.\nAbstract: A 46-year-old woman presented to a local hospital with acute respiratory failure and a 2-year progressive history of fatigue, personality changes, increased sweating, dysphagia with substantial weight loss, dysarthria, and intermittent ptosis and diplopia. Neurological examination showed facial weakness, lingual atrophy and bulbar palsy, which necessitated the use of a feeding tube and ventilatory support. Mild limb weakness with severe muscle atrophy and diffuse muscle twitches were observed. The patient had also developed visual hallucinations and persecutory delusions. Her personal and family medical histories were unremarkable. Sensory and motor nerve conduction studies, repetitive nerve stimulation, electromyogram, blood-cell counts, general chemistry and metabolic function tests, a CT scan, an [(18)F]fluorodeoxyglucose-PET scan, and tests for serum antibodies to acetylcholine receptors, muscle-specific tyrosine kinase, voltage-gated potassium channels, P/Q-type voltage-gated calcium channels, and paraneoplastic antigens, were carried out. Myasthenia gravis associated with antibodies to acetylcholine receptor and muscle-specific tyrosine kinase, and Morvan's syndrome associated with antibodies to voltage-gated potassium channels in the absence of thymoma. Combined treatment with prednisone, intravenous immunoglobulin, ciclosporin, and rituximab.\n\nID: 16986698\nTitle: [Clinical characteristics of elderly Japanese patients with amyotrophic lateral sclerosis; with special reference to the development of respiratory failure].\nAbstract: To clarify the characteristics of elderly-onset amyotrophic lateral sclerosis (ALS). We analyzed the pattern of progression of clinical symptoms and respiratory dysfunction in 26 sporadic ALS patients (19 men, 7 women; mean age 73.2 +/- 6.0 years) with onset at age 65 years or older (E-ALS). We compared the results with those of 28 ALS patients (20 men, 8 women; 53.7 +/- 7.6 years) with younger onset ALS (Y-ALS). Among E-ALS patients, the bulbar palsy type (BP) was the most common (11 patients, 42%) followed by the respiratory failure type (RF) (7 patients, 27%). In contrast, upper extremity type (UE) was the most common (14 patients, 50%) in Y-ALS patients. Mean vital capacity percentage (%VC) at the initial examination was 71.1 +/- 20.4% (vital capacity (VC): 2.12 +/- 0.85 L) in all E-ALS patients, 64.5 +/- 14.5% in BP, 58.1 +/- 5.1% in RF, 94.4 +/- 11.1% in lower extremity type (LE), and 73.9 +/- 30.2% in UE. In all Y-ALS patients, %VC was 90.1 +/- 14.0% (2.94 +/- 0.57 L). The initial % VC value in E-ALS was significantly lower than that in Y-ALS (p < 0.01). VC was lower in RF and BP among E-ALS patients. It was also lower in BP E-ALS patients than in BP Y-ALS patients. Mean period from initial symptom until first examination was significantly shorter in RF in both groups, followed by BP. Twenty-two patients with E-ALS and 26 with Y-ALS died from respiratory failure. Four patients with E-ALS and 2 with Y-ALS required a mechanical ventilator. The mean period until death or ventilation support was 20.9 +/- 10.4 months in E-ALS, and 38.8 +/- 21.1 months in Y-ALS. Significantly shorter survival was observed in E-ALS than Y-ALS (p<0.01). In E-ALS patients, the mean period until death or ventilation support was 21.4 +/- 9.1 months with BP, 10.3 +/- 7.6 months with RF, 29.8 +/- 4.0 months with LE, and 29.3 +/- 5.4 months with UE. This period was significantly shorter in RF patients in both groups, followed by BP patients (p< 0.05, 0.01). Time until death or ventilation support was significantly shorter in BP and UE patients with E-ALS than in those with Y-ALS (p< 0.05). In regard to the progression of respiratory function deterioration, early % VC was lower in E-ALS than in Y-ALS patients, and the period until VC fell below 1 L was shorter. The period until death was particularly short in elderly BP and RF patients, suggesting the possibility that the duration until death from respiratory failure is shorter in E-ALS, because of a decrease in respiratory reverse capacity that accompanies age.\n\nID: 16536121\nTitle: The \"intermediate syndrome\" as critical sequelae of organophosphate poisoning: the first report of two cases in Thailand.\nAbstract: The authors report 2 cases of organophosphate poisoning which developed intermediate syndrome. The first case was a man who took an organophosphate insecticide, monocrotophos, and developed severe organophosphate poisoning. Respiratory support was needed. He was treated with atropine and 2-PAM. Weakness of neck muscles, proximal limb and respiratory muscle developed in the 3rd day after ingestion. By supportive treatment and careful monitoring, however, he recovered after 11 days of the poisoning. The second case was a lady who took dicrotophos. She developed severe organophosphate poisoning for which respiratory support was also needed High dose of atropine, but without 2-PAM, was administered. She developed bulbar palsy, proximal muscle and respiratory weakness 3 day after the ingestion. Ventilation support was needed for 13 days before weaning was successful. This report did not support an efficacy of pralidoxime (2-PAM) in alleviation of the intermediate syndrome, but aims to alert physicians to recognize the intermediate syndrome for which adequate respiratory care is the crucial key for its management.\n\nID: 15605475\nTitle: Pharyngeal-cervical-brachial variant Guillain-Barr\u00e9 syndrome in a child.\nAbstract: The pharyngeal-cervical-brachial variant of Guillain-Barr\u00e9 syndrome is uncommon but well recognized in the adult literature. Patients have weakness in a pharyngeal-cervical-brachial distribution with relative lower limb sparing. We describe a 12-year-old boy with predominantly pharyngeal-cervical-brachial weakness and subsequent respiratory failure. Owing to prominent bulbar symptoms, he was initially misdiagnosed as having epiglottitis. This case illustrates that the clinical spectrum of Guillain-Barr\u00e9 syndrome in children includes the pharyngeal-cervical-brachial variant, which is distinct from Miller-Fisher syndrome. Atypical Guillain-Barr\u00e9 syndrome should be considered in the differential diagnosis of a child presenting with bulbar palsy and/or respiratory failure.\n\nID: 15357267\nTitle: [Two cases of acute respiratory failure associated with pneumonia requiring mechanical ventilation before diagnosis of amyotrophic lateral sclerosis].\nAbstract: We present two cases of acute respiratory failure requiring mechanical ventilation before diagnosis of amyotrophic lateral sclerosis (ALS). The patients were men of 60 (patient 1) and 74-years old (patient 2), both of whom exhibited acute respiratory failure requiring mechanical ventilation. Diagnoses of ALS were made because of continuous aspiration caused by bulbar palsy in patient 1, and, in patient 2, because of the progressive muscle atrophy that occurred during unsuccessful attempts to wean the patient from ventilatory support. Physicians should be aware of the possibility of ALS in cases of acute respiratory failure, CO2 narcosis, continuous aspiration, and difficulty of weaning from mechanical ventilation.\n\nID: 15106480\nTitle: Heimlich manoeuvre: adjunctive emergency procedure to relieve choking and asphyxia.\nAbstract: Choking on aspirated food or a foreign body (i.e. meat, mushroom, coin, chewing gum and a balloon) is a common cause of laryngeal obstruction, particularly in those persons who are intoxicated by alcohol or who have bulbar palsy (degeneration of motor neurons in the brain stem nuclei of the glossopharyngeal and vagal nerve). The rima glottis in the larynx is an important site where aspirated food or material becomes lodged, thereby causing laryngeal obstruction (choking). Because the lungs still contain air, intentional compression thrusts to the abdomen (Heimlich manoeuvre) will theoretically expel air from the lungs and dislodge the entrapped food or other material. The manoeuvre can also be used to expel aspirated water from the airways in cases of near drowning. The manoeuvre has been found to be successful as an emergency adjunct measure in removing food blocking the airway.\n\nID: 14707511\nTitle: A model of neuronopathic Gaucher disease.\nAbstract: Gaucher disease (GD) is a lysosomal disorder involving the accumulation of glucocerebroside in the liver, spleen, bones and brain. Some patients exhibit only systemic disease (type I), but others have additional neurological signs which may lead to rapid neurodegeneration in infancy (type II) or take a more intermediate course (type III). Types II and III are collectively known as neuronopathic Gaucher disease (NGD). Systemic disease can now be treated by enzyme replacement therapy (ERT), but its efficacy in NGD is limited. Two infants who presented with bulbar palsy and failure to thrive were enzymatically diagnosed at 8 months with NGD. They were started on high-dose ERT (120 IU/kg every 2 weeks). Both underwent serial oculomotor assessment and an audiological battery, including visual reinforcement audiometry, otoacoustic emissions, and the auditory brain stem response (ABR). Biochemical markers showed an incomplete systemic response to ERT, but neurological deterioration was relentless, leading to death at 16 and 25 months. Oculomotor testing revealed a complete absence of saccadic eye movements and progressive bilateral sixth nerve palsy in one. Audiological assessment revealed progressive deterioration of ABRs, but with normal peripheral hearing and otoacoustic emissions. Both infants showed neurological deterioration in spite of high-dose ERT. The audiological findings suggested a loss of inner hair cell pathway function with preserved outer hair function, similar to what is seen in auditory neuropathy. The unusual pattern of audiological and oculomotor abnormalities is consistent with an excitotoxic mechanism predisposing nerve cells to glucocerebroside toxicity. Such excitotoxic damage may be amenable to direct therapeutic intervention.\n\nID: 9493205\nTitle: [A 49-year-old man with progressive bulbar palsy and respiratory failure].\nAbstract: We report a 49-year-old man with progressive bulbar palsy and respiratory failure. He was well until his 48 years of the age (December 1994) when he noted a difficulty in speaking in loud voice. In February, 1995, he noted regurgitation of foods to his nose and difficulty in his speech. He was admitted to our service in May 29, 1995. On admission, he was alert and oriented to all spheres and he was not demented. His higher cerebral functions were normal. In cranial nerves, he showed dysarthria and dysphagia; muscle atrophies were seen in the tongue, the bilateral sternocleidomastoid, supraspinatus, and infraspinatus muscles. Fasciculations were seen in these muscles. He showed no muscle weakness in his limbs except for the upper limb girdle muscles, no ataxia, no reflex abnormalities, nor sensory changes. EMG showed neurogenic changes in the affected muscles. MRI of the brain and the spinal cord was entirely normal. He was discharged for out patient follow-up, however, in October of 1995, he noted difficulty in swallowing solid foods. Gastrostomy was placed and he was discharged to his home. In February 11th of 1996, he was found unresponsive and brought into the ER of our hospital. On admission, he was comatose without spontaneous respiration. BP could not be obtained. He was immediately intubated and artificial ventilation was started. On the following morning, he became alert and he was not demented. He continued to show marked dysarthria and dysphagia; again no weakness was noted in the distal parts of the upper and lower extremities. Laboratory examination showed increase in serum CK to 2,173 IU/L and amylase to 2,032 IU/L. He was extubated on February 15th, however, his spontaneous respiration was not suffice to maintain his blood gas. According to his will, he was not placed on respirator and he died on February 24th, 1996. The patient was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had ALS. Although no upper neuron signs were observed clinically, it is not uncommon to see degeneration in the corticospinal tract in post-mortem examination. The question was what might have been the cause of increase in CK and amylase. Many participants thought that they were secondary to multiple organ failure due to prolonged hypoxic state at his last admission; other possibilities raised included acute myocardial infarction and acute bowel necrosis. Post-mortem examination revealed muscle atrophy in the facial, lingual, cervical, intercostal, and the upper limb girdle areas. The lungs were unremarkable except for old organized pneumonic foci in the right middle and lower lobes. Marked to moderate congestion was seen in many internal organs, however, no other gross abnormality was found. It was thought that respiratory palsy itself was the direct cause of his agonal event. In the spinal cord, the anterior horns showed various degree of neuronal loss and gliosis. No clear evidence of pyramidal tract degeneration was seen at the light microscope level. Lower brain stem motor neurons were markedly reduced. But no Bunina body was found. The substantia nigra showed moderate degree of neuronal loss and extraneuronal neuromelanins. The locus coeruleus showed similar but milder changes. The degree of nigral degeneration appeared to be well beyond those which could be seen in usual ALS patients. The question was whether or not this patient might have been in an early stage of the extended form of ALS.\n\nID: 7994999\nTitle: [A case of multiple sclerosis with intractable hiccup and acute respiratory arrest].\nAbstract: A 41-year-old woman with multiple sclerosis (MS) manifesting optic neuritis, cerebellar ataxia and myelopathy was admitted for intractable hiccup and aggravation of sensory disturbance in both lower limbs. Magnetic resonance imaging (MRI) revealed a Gd-DTPA enhanced lesion from the level of the medulla oblongata, involving the reticular formation, to that of the vertebral body C2. She became abruptly unable to breath following aggravation of bulbar palsy and tetraplegia and mechanical ventilation was immediately initiated. The next day, voluntary breathing re-appeared but automatic respiratory failure remained unchanged. The respirator was completely removed after one month, and then the breathing was almost normal. In MS patients who develop intractable hiccup as an early symptom, it is suggested that the causative lesion is in the medulla oblongata. In such cases, we must carefully observe the clinical course because expansion of the lesion may induce respiratory failure.\n\nID: 8252836\nTitle: [Acute respiratory arrest associated with medullary lesion in a case of multiple sclerosis].\nAbstract: We present a case history of a patient with multiple sclerosis who developed an abrupt onset of respiratory arrest associated with medullary lesion. A 27-year-old man developed shallow, totally irregular, ataxic respirations with aggravation of bulbar palsy and quadriplegia in the course of multiple sclerosis. As respiration was almost arrested, artificial respiration was started and continued for five days. Respiration was almost normal after 16 days from the onset of respiratory arrest. MRI showed bilateral, medullary lesions without upper cervical lesions. Pyramidal tracts, medial lemnisci, and paramedian reticular formations in medulla were damaged bilaterally. We supposed that the medullary lesions involved dual respiratory systems: a voluntary system and an automatic system, and caused acute respiratory arrest.\n\nID: 8319389\nTitle: [A case of hereditary motor and sensory neuropathy with vocal cords palsy and diaphragmatic weakness].\nAbstract: A case of hereditary motor and sensory neuropathy (HMSN) type 1 (Charcot-Marie-Tooth disease (CMT)) is reported with vocal cords palsy, deafness, diaphragmatic weakness, and cerebellopontine atrophy. A 42-year-old man was admitted to our hospital in April, 1991 with marked respiratory distress. He had been diagnosed as having CMT 14 years previously. On admission to our hospital, he revealed dyspnea with marked stridor during inspiration. Physical examination showed marked use of respiratory accessory muscles with thoracoabdominal paradox in the supine position. Neurologic examination revealed tonic pupils, mild bilateral weakness of facial muscles, deafness, mild bulbar palsy, severe wasting and weakness in both proximal and distal muscles of the arms and legs, areflexia, distal loss of all sensory modalities. Pes cavus and hammer toe were present. Movement of upper extremities was ataxic. No hypertrophic changes were noted in his peripheral nerves. Peripheral nerve conduction study showed undetectable both sensory and motor action potentials. Electromyography showed evidence of denervation, more marked in distal muscles. Auditory brain stem response was undetectable. Chest radiographic film showed a normal-sized heart with marked elevation of both hemidiaphragm. Laryngofiberscopy confirmed the presence of bilateral vocal cord paralysis without tumor formation, inflammation or anomaly. The vocal cords lay near the midline and did not show any movement during respiration. Moderate cerebellopontine atrophy was confirmed on MRI scan. A sural nerve section showed severe decrease of myelinated fibers, and onion bulbs. Diagnosis of HMSN type 1 was made by clinical, electrodiagnostic, and sural nerve sections study.(ABSTRACT TRUNCATED AT 250 WORDS)\n\nID: 2044852\nTitle: 'Pure' and 'complicated' forms of hereditary spastic paraplegia presenting in childhood.\nAbstract: Of 23 children with hereditary spastic paraplegia (HSP), spasticity was the only neurological abnormality in eight patients (pure form). Additional neurological abnormalities in the 15 with complicated HSP included cognitive impairment, pseudo-bulbar palsy, cerebellar dysfunction and polyneuropathy. 19 children presented with abnormal gait, recognised at a mean age of three years in the pure form and five years in the complicated form. These forms were distinguished at a mean age of 11 years. Early non-motor developmental delay or rapidly ascending paraparesis, with spread of spasticity to the arms and with involvement of bulbar structures, predicted development of the complicated form. The pure form was inherited in an autosomal dominant manner in five patients. The autosomal recessive form was commonly associated with additional neurological abnormalities and a more rapid rate of progression.\n\nID: 3147318\nTitle: Subacute administration of a TRH analogue (RX77368) in motorneuron disease: an open study.\nAbstract: Sixteen patients with motor neuron disease received RX77368, a TRH analogue, IV, repeatedly over 1-12 weeks (median 2 weeks). Slight to moderate improvement in bulbar function, particularly speech, was reproduced or persisted with repeated infusions in 8 of 12 responders over a median of 18 days (range 14-90) during the period of study. Cramps (5/9) and spasticity (5/8) improved for a median of 14 days (range 7-35) and 7 days (range 2-14) respectively. The highest benefit/side effect ratio was seen with 0.2 mg/kg (0.15 mg/kg in those with severe bulbar palsy) every 3-4 days. Long term studies with this analogue in MND are indicated.\n\nID: 3724629\nTitle: Paralysis with Ixodes cornuatus envenomation.\nAbstract: Ixodes cornuatus is a tick that is widely distributed in Victoria, Tasmania and southern New South Wales. Serious human envenomation has not been reported previously. The clinical syndrome that results from envenomation by Ixodes cornuatus in a three-year-old boy is presented. Bulbar palsy and respiratory failure necessitated endotracheal intubation and mechanical ventilation for five days. Canine tick antivenom was administered.\n\nID: 36003035\nTitle: Amyotrophic lateral sclerosis with TDP-43 abnormalities exhibiting globular glial tau inclusions in frontotemporal lobes and pallido-nigral system.\nAbstract: Here we present the autopsy case of an 80-year-old woman with a 9-year history of motor neuron disease and atypical Parkinsonism. Her initial symptom was gait disturbance, and she subsequently developed limb weakness and Parkinsonism without response to levodopa. Her motor symptoms progressed to bulbar palsy, and she died of respiratory failure. Postmortem examination revealed characteristic findings of amyotrophic lateral sclerosis (ALS), including motor neuronal loss with astrogliosis, corticospinal tract degeneration, and TAR DNA-binding protein of 43\u2009kDa abnormalities, including nuclear loss and skein-like inclusions. In contrast, severe tau pathological changes were seen in the frontotemporal lobes and pallido-nigral system. Tau pathologies affected not only neuronal components, such as neurofibrillary tangles and neuropil threads, but also glial cells (astrocytes and oligodendrocytes). Some glial tau pathologies exhibited peculiar round accumulations, reminiscent of globular glial inclusions (GGIs) in globular glial tauopathy. This unique autopsy case demonstrates that ALS with TDP-43 could be comorbid with globular glial tau inclusions and indicates that common pathological mechanisms exist among ALS and GGI formation.\n\nID: 33953791\nTitle: The Novel Regulatory Role of lncRNA-miRNA-mRNA Axis in Amyotrophic Lateral Sclerosis: An Integrated Bioinformatics Analysis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is an incurable neurodegenerative disease that primarily affects motor neurons, causing muscle atrophy, bulbar palsy, and pyramidal tract signs. However, the aetiology and pathogenesis of ALS have not been elucidated to date. In this study, a competitive endogenous RNA (ceRNA) network was constructed by analyzing the expression profiles of messenger RNAs (mRNAs) and long noncoding RNAs (lncRNAs) that were matched by 7 ALS samples and 4 control samples, and then a protein-protein interaction (PPI) network was constructed to identify the genes related to ALS. Gene Ontology (GO) was used to study the potential functions of differentially expressed mRNAs (DEmRNAs) in the ceRNA network. For the ALS and control groups, 247177 potential lncRNA-mRNA ceRNA relationship pairs were screened. Analysis of significant relationship pairs demonstrated that the PPI modules formed by the MALAT1-regulated SYNRG, ITSN2, PICALM, AP3B1, and AAK1 genes may play important roles in the pathogenesis of ALS, and these results may help to characterize the pathogenesis of ALS.\n\nID: 32909658\nTitle: Hematologic presentation and the role of untargeted metabolomics analysis in monitoring treatment for riboflavin transporter deficiency.\nAbstract: Riboflavin transporter deficiency (RTD) (MIM #614707) is a neurogenetic disorder with its most common manifestations including sensorineural hearing loss, peripheral neuropathy, respiratory insufficiency, and bulbar palsy. Here, we present a 2-year-old boy whose initial presentation was severe macrocytic anemia necessitating multiple blood transfusions and intermittent neutropenia; he subsequently developed ataxia and dysarthria. Trio-exome sequencing detected compound heterozygous variants in SLC52A2 that were classified as pathogenic and a variant of uncertain significance. Bone marrow evaluation demonstrated megaloblastic changes. Notably, his anemia and neutropenia resolved after treatment with oral riboflavin, thus expanding the clinical phenotype of this disorder. We reiterate the importance of starting riboflavin supplementation in a young child who presents with macrocytic anemia and neurological features while awaiting biochemical and genetic work up. We detected multiple biochemical abnormalities with the help of untargeted metabolomics analysis associated with abnormal flavin adenine nucleotide function which normalized after treatment, emphasizing the reversible pathomechanisms involved in this disorder. The utility of untargeted metabolomics analysis to monitor the effects of riboflavin supplementation in RTD has not been previously reported.\n\nID: 32671738\nTitle: Autophagy and Motor Neuron Diseases.\nAbstract: Motor neuron diseases (MND) are a group of fatal progressive neurodegenerative diseases, which selectively affect the motor system in the anterior horn of spinal cord, brainstem, cortex and pyramidal tract. Motor neurons could be divided into two groups, which are upper groups in the motor cortex and lower groups in the brain stem and spinal cord. Loss of lower motor neurons leads to muscle weakness, wasting and cramps. Loss of upper motor neurons leads to brisk reflexes and functional limits. There are several types of motor neuron disease: amyotrophic lateral sclerosis (ALS), progressive bulbar palsy (PBP), progressive muscular atrophy (PMA), primary lateral sclerosis (PLS). Now, the studies of autophagy in MND focus on the type of ALS, so this chapter will summarize the alteration of autophagy in motor neurons, and how that knowledge contributes to our understanding of the pathogenesis of ALS.\n\nID: 31124595\nTitle: p.N345K mutation in TARDBP in a patient with familial amyotrophic lateral sclerosis: An autopsy case.\nAbstract: We report the neuropathology of a patient with a family history of amyotrophic lateral sclerosis (ALS) and a p.N345K mutation in the transactivation response DNA-binding protein 43 kDa (TDP-43) gene (TARDBP). A 62-year-old man had bulbar palsy with progressive weakness in the extremities. Neurological examination revealed evident upper motor neuron signs and lower motor neuron involvement corroborated by needle electromyography. The patient was diagnosed as having probable ALS according to the revised El Escorial diagnostic criteria and was eventually diagnosed with familial ALS. At 65\u2009years of age, respiratory failure became critical, and artificial ventilation was initiated. At 70\u2009years of age, the patient died from a urinary tract infection. Histopathological investigation showed Bunina bodies in the remaining motor neurons and anterolateral funicular myelin pallor in the spinal cord. TDP-43-positive cytoplasmic inclusions were quite rare in the spinal cord motor neurons, being predominantly present in the glial cells (especially astrocytes) of the spinal cord anterior horn. Although the reason for the preferential vulnerability of spinal glial cells to TARDBP mutations remains unclear, our findings indicate that TARDBP p.N345K mutation could have an influence on the topography of TDP-43 aggregation.\n\nID: 30123989\nTitle: Autopsy-proven case of paraneoplastic lower motor neuron disease with sensorimotor neuropathy due to Waldenstr\u00f6m's macroglobulinemia.\nAbstract: We report a case of a male patient with a 19-year history of monoclonal and later polyclonal gammopathy who subsequently developed tetraparesis, bulbar palsy, and respiratory failure. Autopsy findings showed degeneration of the hypoglossal nuclei, prominent neuronal loss and atrophy in the anterior horn of the whole spinal cord despite the presence of mild astrocytosis, degeneration of the gracilis on one side, and infiltration of inflammatory cells, which included B cells and plasma cells in the anterior and posterior roots of the lumbar spinal cord, iliopsoas muscle, and perivascular area of the cervical cord. On immunostaining, cytoplasmic inclusions of phosphorylated transactivation response DNA-binding protein of 43\u2009kDa were observed in the motor neurons and astrocytes of the hypoglossal nuclei and whole spinal cord. The final diagnosis was paraneoplastic lower motor neuron disease with sensorimotor neuropathy due to Waldenstr\u00f6m's macroglobulinemia.\n\nID: 25206632\nTitle: MAPT as a predisposing gene for sporadic amyotrophic lateral sclerosis in the Chinese Han population.\nAbstract: A previous study of European Caucasian patients with sporadic amyotrophic lateral sclerosis demonstrated that a polymorphism in the microtubule-associated protein Tau (MAPT) gene was significantly associated with sporadic amyotrophic lateral sclerosis pathogenesis. Here, we tested this association in 107 sporadic amyotrophic lateral sclerosis patients and 100 healthy controls from the Chinese Han population. We screened the mutation-susceptible regions of MAPT - the 3' and 5' untranslated regions as well as introns 9, 10, 11, and 12 - by direct sequencing, and identified 33 genetic variations. Two of these, 105788 A > G in intron 9 and 123972 T > A in intron 11, were not present in the control group. The age of onset in patients with the 105788 A > G and/or the 123972 T > A variant was younger than that in patients without either genetic variation. Moreover, the pa-tients with a genetic variation were more prone to bulbar palsy and breathing difficulties than those with the wild-type genotype. This led to a shorter survival period in patients with a MAPT genetic variant. Our study suggests that the MAPT gene is a potential risk gene for sporadic amyotrophic lateral sclerosis in the Chinese Han population.\n\nID: 25036750\nTitle: Accelerated neuronal differentiation toward motor neuron lineage from human embryonic stem cell line (H9).\nAbstract: Motor neurons loss plays a pivotal role in the pathoetiology of various debilitating diseases such as, but not limited to, amyotrophic lateral sclerosis, primary lateral sclerosis, progressive muscular atrophy, progressive bulbar palsy, pseudobulbar palsy, and spinal muscular atrophy. However, advancement in motor neuron replacement therapy has been significantly constrained by the difficulties in large-scale production at a cost-effective manner. Current methods to derive motor neuron heavily rely on biochemical stimulation, chemical biological screening, and complex physical cues. These existing methods are seriously challenged by extensive time requirements and poor yields. An innovative approach that overcomes prior hurdles and enhances the rate of successful motor neuron transplantation in patients is of critical demand. Iron, a trace element, is indispensable for the normal development and function of the central nervous system. Whether ferric ions promote neuronal differentiation and subsequently promote motor neuron lineage has never been considered. Here, we demonstrate that elevated iron concentration can drastically accelerate the differentiation of human embryonic stem cells (hESCs) toward motor neuron lineage potentially via a transferrin mediated pathway. HB9 expression in 500\u2009nM iron-treated hESCs is approximately twofold higher than the control. Moreover, iron treatment generated more matured and functional motor neuron-like cells that are \u223c1.5 times more sensitive to depolarization when compared to the control. Our methodology renders an expedited approach to harvest motor neuron-like cells for disease, traumatic injury regeneration, and drug screening.\n\nID: 23064625\nTitle: [Autopsy case of a patient with Charcot-Marie-Tooth disease type 1A and suspected chronic inflammatory demyelinating polyradiculoneuropathy, which was later diagnosed as amyotrophic lateral sclerosis].\nAbstract: We report an autopsy case of a 74-year-old man with late onset Charcot-Marie-Tooth disease type 1A (CMT1A) diagnosed by genetic screening, later associated with amyotrophic lateral sclerosis (ALS). At the age of 70 years, the patient was admitted to our hospital because of progressive weakness and dysesthesia in the right upper limb. In the early stages of the illness, he was diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and transient improvement was achieved with intravenous immunoglobulin. However, the symptoms progressively worsened and became refractory. Gene analysis revealed PMP22 gene duplication, which confirmed CMT1A. On sural nerve biopsy, severe demyelinating neuropathy and abundant onion-bulb formations with endoneurial infiltration of inflammatory cells were observed. Thereafter, pseudo-bulbar palsy and respiratory muscle weakness developed insidiously and progressed rapidly along with muscle weakness in the limbs and trunk. The patient died about four years after the onset of this disease. Postmortem examination showed moderate neuronal cell loss, Bunina bodies, and TDP-43-positive inclusions in the anterior horn cells. The spinal cord revealed axonal loss and extensive macrophage permeation in the corticospinal tracts. On the basis of these findings, the final neuropathological diagnosis was ALS. This is the first report of an autopsy case of CMT1A complicated with ALS. We here discuss the significant clinical and neuropathological findings of this case.\n\nID: 22864630\nTitle: Impaired riboflavin transport due to missense mutations in SLC52A2 causes Brown-Vialetto-Van Laere syndrome.\nAbstract: Brown-Vialetto-Van Laere syndrome (BVVLS [MIM 211530]) is a rare neurological disorder characterized by infancy onset sensorineural deafness and ponto-bulbar palsy. Mutations in SLC52A3 (formerly C20orf54), coding for riboflavin transporter 2 (hRFT2), have been identified as the molecular genetic correlate in several individuals with BVVLS. Exome sequencing of just one single case revealed that compound heterozygosity for two pathogenic mutations in the SLC52A2 gene coding for riboflavin transporter 3 (hRFT3), another member of the riboflavin transporter family, is also associated with BVVLS. Overexpression studies confirmed that the gene products of both mutant alleles have reduced riboflavin transport activities. While mutations in SLC52A3 cause decreased plasma riboflavin levels, concordant with a role of SLC52A3 in riboflavin uptake from food, the SLC52A2-mutant individual had normal plasma riboflavin concentrations, a finding in line with a postulated function of SLC52A2 in riboflavin uptake from blood into target cells. Our results contribute to the understanding of human riboflavin metabolism and underscore its role in the pathogenesis of BVVLS, thereby providing a rational basis for a high-dose riboflavin treatment.\n\nID: 22409359\nTitle: Marked intrafamilial phenotypic variation in a family with SOD1 C111Y mutation.\nAbstract: Our objectives were to identify the disease-causing mutation in, and report on the clinical features of, a Japanese family that had coexisting phenotypes of amyotrophic lateral sclerosis and spinal muscular atrophy. The family comprised nine patients (six men and three women). We reviewed their clinical records and performed mutation analysis of the copper/zinc superoxide dismutase (SOD1) gene in some of these patients. The patients either had a rapid (n=7) or an extremely long (n=2) clinical course. The mean age at onset was 39.0\u00b113.7 years (range 20-68 years). The initial symptoms were bulbar palsy (n=2), upper (n=4) or lower (n=2) limb muscle weakness, or leg cramps (n=1). The total disease duration varied widely, ranging from one year to >69 years. We identified a SOD1 C111Y mutation among patients in this family. In conclusion, the family showed a marked intrafamilial phenotypic variation associated with the SOD1 C111Y mutation. Elucidating the biological basis of disease expression in patients with the SOD1 C111Y mutation may provide us with useful information to develop therapeutic approaches and to prevent disease progression.\n\nID: 12563402\nTitle: [Central pontine and extra-pontine myelinolysis in an alcoholic patient without hydro-electrolyte disturbances: case report].\nAbstract: Central pontine myelinolysis (CPM) and extra-pontine myelinolysis (EPM) are different presentations of a demyelinating disorder of the brain more commonly associated with rapid correction of hyponatremia, spastic tetraparesia and pseudo-bulbar palsy. There are in the literature a few cases of CPM/EPM in patients without electrolyte disturbances. We report the case of a 39 year-old man with severe alcoholism, who presented with spastic tetraparesis and palsy of several cranial nerves, associated with lesions in the magnetic resonance compatible with CPM/EPM. The patient had a good follow-up after pulse therapy with corticosteroids.\n\nID: 10686412\nTitle: Immunocytochemical and ultrastructural study of the motor cortex in patients with lower motor neuron disease.\nAbstract: This report conveys the results of an immunocytochemical and ultrastructural study of the motor cortices of six patients with clinically and pathologically-diagnosed lower motor neuron disease (LMND) such as progressive spinal muscular atrophy, progressive bulbar palsy, or both. These patients showed neither upper motor neuron signs nor upper motor neuron system involvement including the corticospinal tract in postmortem tissues after conventional stainings. Specimens from 12 age-matched normal individuals served as controls. All patients showed loss of brainstem motor neurons and anterior horn cells. Betz cells in LMND patients were significantly reduced in number as compared to controls (P<0.01). However, there was no significant difference in the density of phosphorylated neurofilament (PNF) (200 kDa)-positive Betz cells between LMND patients and controls. The pyramidal cells of layer III were immunostained for PNF in four of six LMND patients, but there was no significant difference in the density of PNF-positive pyramidal cells between LMND patients and controls. The number of astrocytes immunostained for glial fibrillary acidic protein increased in layer III and at the transition between white matter and motor cortex in three out of six patients and one of 12 controls. Ultrastructural examination revealed that the Betz cells of five of six LMND patients had Bunina bodies, Lewy body-like inclusions or skein-like inclusions, all of which are characteristic of amyotrophic lateral sclerosis (ALS). These findings suggest that most patients with clinically and pathologically-diagnosed LMND should be classified into the category of ALS.\n\nID: 18616153\nTitle: [Case of primary intraocular central nervous system lymphoma with high interleukin 10 level and positive cytology in cerebrospinal fluid].\nAbstract: A 73-year-old woman was admitted to the surgical department of our hospital for endoscopic resection of a colonic polyp. The day after endoscopic resection, she became drowsy and dysphasic. Two days later, left hemiparesis and gait difficulty developed. The next day, hemiparesis progressed bilaterally and dyspnea developed due to upper airway stenosis. The most prominent signs were those of bulbar palsy. Blood analysis revealed mild inflammatory responses and hyponatremia. T2-weighted magnetic resonance imaging showed high-intensity lesions in the swollen medulla and cervical spinal cord. Those areas and the meninges of the posterior fossa were enhanced by gadolinium. Steroid pulse therapy was administered, resulting in rapid recovery of bulbar and paretic symptoms with decreased enhanced area. At this point, concentration of cerebrospinal fluid interleukin (IL)-10 was markedly elevated at 146 pg/ml (normal,< 5 pg/ml), suggesting malignant lymphoma. Cytology of the cerebrospinal fluid was repeatedly examined, eventually revealing atypical lymphocytes with hyperlobulated nuclei and clear nucleoli. Lymphocytes stained with anti-CD20 antibody. These findings strongly suggested a diagnosis of primary intraocular and central nervous system lymphoma. In the present case, repeated cytology of cerebrospinal fluid was highly important for diagnosis in this case of high IL-10 level in cerebrospinal fluid.\n\nID: 3027429\nTitle: [An autopsy case of meningeal carcinomatosis with vestibulocochlear nerve disturbance as the first manifestation].\nAbstract: A 54-year-old man initially complained of frontal headache, right ear pain and tinnitus in May, 1985. This was followed by right facial palsy and hearing loss, and he was admitted to our hospital. Physical findings revealed right trigeminal nerve disturbance, left facial nerve palsy and bulbar palsy. The spinal fluid showed pleocytosis, increased protein, decreased glucose, markedly increased carcinoembryonic antigen and adenocarcinoma cells. Gastric carcinoma was revealed by an upper GI series. He was treated with chemotherapy. However, he die in August, 1985. Nodular metastases were discovered at the right internal acoustic meatus and other areas. Microscopically, signet-ring cell carcinoma had diffusely infiltrated at the subarachnoid space.\n\nID: 14147770\nTitle: CONGENITAL FLACCID BULBAR PALSY.\nAbstract: \n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov.

Methods: A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children's Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results: A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71\u00b18) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23\u00b13) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge (Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions: Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment. \u76ee\u7684\uff1a \u603b\u7ed3\u513f\u7ae5\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u7684\u4e34\u5e8a\u7279\u70b9\u3001\u6cbb\u7597\u53ca\u9884\u540e\u3002 \u65b9\u6cd5\uff1a \u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\uff0c\u9009\u62e92019\u5e743\u6708\u81f32024\u5e7412\u6708\u5728\u5e7f\u5dde\u533b\u79d1\u5927\u5b66\u9644\u5c5e\u5987\u5973\u513f\u7ae5\u533b\u7597\u4e2d\u5fc3\u795e\u7ecf\u5185\u79d1\u4e34\u5e8a\u8bca\u65ad\u4e3a\u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u768425\u4f8b\u60a3\u513f\uff0c\u6536\u96c6\u5e76\u5206\u6790\u5176\u4e34\u5e8a\u8d44\u6599\u53ca\u6cbb\u7597\u968f\u8bbf\u8d44\u6599\u3002\u91c7\u7528Mann-Whitney U\u68c0\u9a8c\u6bd4\u8f83\u60a3\u513fHughes\u529f\u80fd\u5206\u7ea7\u8bc4\u5206\uff08HFGS\uff09\u53d8\u5316\u3002 \u7ed3\u679c\uff1a 25\u4f8b\u60a3\u513f\u753712\u4f8b\u3001\u597313\u4f8b\uff0c\u9996\u6b21\u53d1\u75c5\u5e74\u9f84\u4e3a\uff0871\u00b18\uff09\u6708\u9f84\u300216\u4f8b\uff0864%\uff09\u6709\u524d\u9a71\u611f\u67d3\uff0c\u5176\u4e2d13\u4f8b\u4e3a\u547c\u5438\u9053\u611f\u67d3\u3002\u75be\u75c5\u9ad8\u5cf0\u65f6\u795e\u7ecf\u7cfb\u7edf\u75c7\u72b6\u5305\u62ec\u80a2\u4f53\u65e0\u529b21\u4f8b\uff0884%\uff09\u3001\u7403\u9ebb\u75f913\u4f8b\uff0852%\uff09\u3001\u55dc\u77617\u4f8b\uff0828%\uff09\u3001\u80a2\u4f53\u75bc\u75db9\u4f8b\uff0836%\uff09\u3001\u5171\u6d4e\u5931\u8c036\u4f8b\uff0824%\uff09\u3001\u547c\u5438\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u773c\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u5355\u4fa7\u9762\u795e\u7ecf\u9ebb\u75f94\u4f8b\uff0816%\uff09\u300223\u4f8b\u60a3\u513f\u8111\u810a\u6db2\u68c0\u67e5\uff0c\u86cb\u767d-\u7ec6\u80de\u5206\u79bb18\u4f8b\u300225\u4f8b\u60a3\u513f\u5168\u810a\u67f1\u78c1\u5171\u632f\u6210\u50cf\uff08MRI\uff09\u68c0\u67e5\u793a\u810a\u795e\u7ecf\u6839\u5f3a\u531618\u4f8b\uff0c\u67d4\u8111\u819c\u5f3a\u5316\u5408\u5e76\u810a\u795e\u7ecf\u6839\u5f3a\u53161\u4f8b\u300216\u4f8b\u60a3\u513f\u63a5\u53d7\u808c\u7535\u56fe\u68c0\u67e5\uff0c15\u4f8b\u5f02\u5e38\uff0c\u5176\u4e2d\u8131\u9ad3\u9798\u75c5\u53d88\u4f8b\u3001\u8131\u9ad3\u9798\u5408\u5e76\u8f74\u7d22\u75c5\u53d84\u4f8b\uff0c\u8f74\u7d22\u75c5\u53d83\u4f8b\u3002\u9759\u8109\u8f93\u6ce8\u514d\u75ab\u7403\u86cb\u767d\uff08IVIG\uff09\u6cbb\u7597 21\u4f8b\uff0884%\uff09\uff0c\u5176\u4e2d3\u4f8b\u60a3\u513fIVIG\u6cbb\u7597\u540e\u75c5\u60c5\u8fdb\u5c55\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\u884c\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u53ca\u8840\u6db2\u51c0\u5316\u6cbb\u7597\uff0c\u5305\u62ec\u8840\u6d46\u7f6e\u63622\u4f8b\u3001\u514d\u75ab\u5438\u9644\u6cbb\u75971\u4f8b\u30024\u4f8b\u60a3\u513f\u62d2\u7eddIVIG\u6cbb\u7597\u63a5\u53d7\u9759\u8109\u8f93\u6ce8\u7532\u6cfc\u5c3c\u9f99\uff08IVMP\uff09\u6cbb\u7597\uff0c\u5176\u4e2d1\u4f8b\u56e0\u547c\u5438\u808c\u9ebb\u75f9\u63a5\u53d7\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u6cbb\u7597\uff0c\u7ee7\u7eedIVMP\u5e8f\u8d2f\u6cbb\u7597\u540e\u62d4\u9664\u6c14\u7ba1\u63d2\u7ba1\u300225\u4f8b\u60a3\u513f\u9996\u6b21\u53d1\u75c5\u6025\u6027\u671f\u7684\u4f4f\u9662\u65f6\u95f4\u4e3a\uff0823\u00b13\uff09d\uff0c\u51fa\u9662\u65f6HFGS 1.6\uff080.6\uff0c2.7\uff09\u5206\uff0c\u9996\u6b21\u53d1\u75c5\u51fa\u9662\u81f3\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u7684\u65f6\u95f4\u95f4\u9694\u4e3a12\uff084\uff0c18\uff09\u4e2a\u6708\uff0cHFGS 0.1\uff080.0\uff0c0.5\uff09\u5206\uff0c\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u65f6HFGS\u4f4e\u4e8e\u51fa\u9662\u65f6\uff08Z=4.38\uff0cP<0.05\uff09\u30022\u4f8b\u60a3\u513f\u590d\u53d1\uff0c\u518d\u6b21\u4e88IVIG\u6cbb\u7597\u540e\u7f13\u89e3\uff0c\u968f\u8bbf1\u5e74\u672a\u518d\u590d\u53d1\u3002 \u7ed3\u8bba\uff1a \u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u6025\u6027\u671f\u5e38\u89c1\u7684\u75c7\u72b6\u4e3a\u80a2\u4f53\u65e0\u529b\u53ca\u7403\u9ebb\u75f9\uff0c\u4e25\u91cd\u8005\u53ef\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\uff0c\u808c\u7535\u56fe\u4ee5\u8131\u9ad3\u9798\u75c5\u53d8\u591a\u89c1\uff0cMRI\u810a\u795e\u7ecf\u6839\u5316\u5e38\u89c1\uff0c\u591a\u6570\u60a3\u513fIVIG\u514d\u75ab\u6cbb\u7597\u6548\u679c\u826f\u597d\uff0c\u65e0\u4e25\u91cd\u795e\u7ecf\u7cfb\u7edf\u540e\u9057\u75c7\u6b8b\u7559\u3002\u5c11\u6570\u60a3\u513f\u53ef\u80fd\u590d\u53d1\u3002.\n  --- END ACTUAL ABSTRACT FOR 40962541 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR;

Current literature emphasizes quantitative assessments of lingual dysfunction and novel interventions for dysphagia. The claim regarding breakthroughs in July 2026 is chronologically unsupported by the provided context, which contains data reaching only through 2025.\n\n### [INTRODUCTION & JUSTIFICATION]\nBulbar palsy manifests as a clinical sign of neuromuscular degeneration, significantly complicating patient outcomes in ALS and GBS. The provided evidence indicates that clinical breakthroughs are primarily centered on non-invasive diagnostic methodologies and nutritional support strategies rather than a singular therapeutic milestone in mid-2026. Quantitative imaging, specifically the use of shear wave elastography and neural network-based tongue volume segmentation, represents a significant shift toward unbiased, objective longitudinal tracking. Furthermore, the standardization of GBS respiratory failure assessment through models like the mEGRIS tool, which integrates bulbar palsy as a high-risk predictor, marks a definitive shift in clinical management. Interventions such as intermittent oro-esophageal feeding and ultrasound-guided stellate ganglion blocks demonstrate that management of secondary symptoms in BP remains the primary area of active research.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Bulbar palsy functions as an independent, high-value predictor for respiratory muscle paralysis in GBS.\n*   Tongue shear wave elastography provides a non-invasive objective metric for correlating bulbar symptom severity with muscle elasticity.\n*   Automated CNN-based segmentation allows for precise monitoring of tongue atrophy in progressive bulbar palsy (PBP) variants.\n*   Intermittent oro-esophageal tube feeding (IOE) significantly reduces complications related to malnutrition and pneumonia compared to traditional nasogastric methods.\n*   Stellate ganglion blocks show promise in improving swallowing function and airway protection by transiently increasing vertebral artery blood flow.\n*   Clinical diagnostic criteria for ALS often require integrated neuroimaging and electrophysiological evaluation to differentiate between PBP and other MND phenotypes.\n*   The inclusion of Platelet-to-Lymphocyte Ratio (PLR) in predictive models for pediatric GBS respiratory failure adds incremental clinical value.\n*   Rare cases of locked-in syndrome (LIS) secondary to vertebral artery dissection demonstrate that bulbar palsy can manifest acutely following mechanical interventions.\n*   Biallelic DNAJC7 mutations establish a genetic pathway linking protein homeostasis, TDP-43 pathology, and PBP.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy.

A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS."

Radiological diagnostics primarily serve to systematically exclude treatable mimics and support the clinical and electrophysiological diagnosis. The focus is on amyotrophic lateral sclerosis (ALS); supplementary progressive muscular atrophy (PMA, purely lower motor neuron, LMN disease) and spinal muscular atrophy (SMA). Which imaging signs support the diagnosis of ALS, how do electromyography/magnetic resonance imaging (EMG/MRI) fit into the Gold Coast criteria and which other motor neuron diseases are relevant? Overview of clinical criteria (Gold Coast), genetics and typical MRI findings of the brain, spinal cord and musculature. Gold Coast core: progressive motor deterioration, upper motor neuron (UMN) and LMN signs in \u2265\u202f1 region or LMN in \u2265\u202f2\u00a0regions and exclusion of alternative causes. susceptibility-weighted imaging (SWI) motor band sign as UMN marker; T2/fluid-attenuated inversion recovery (FLAIR) hyperintensities along the corticospinal tract with low sensitivity, moderate specificity; T1 bright tongue as an indication of chronic denervation in bulbar involvement. EMG: detection of subclinical LMN involvement, sometimes limited in UMN-dominant/bulbar courses. PMA: Pure purely LMN symptoms, often continuum to ALS. SMA: Autosomal autosomal recessive (SMN1 deletion). The diagnosis remains primarily clinical; EMG and MRI are supportive. The radiological priority is the exclusion of mimics. The UMN markers increase diagnostic certainty in the context of clinical/EMG findings but do not replace them. Clear findings facilitate classification according to Gold Coast. The PMA and SMA require careful differential diagnostics; characteristic MRI patterns support progression and treatment planning.

The clinical presentation, coupled with the patient's report of the firework emitting a green flare, is most consistent with acute barium toxicity. Formal toxicologic confirmation was not available; however, the clinical constellation, mechanism of injury, and rapid response to electrolyte repletion strongly support this diagnosis. Barium salts, commonly used in pyrotechnics to produce green coloration, can induce systemic toxicity by competitively blocking potassium channels, causing a widespread intracellular shift of potassium. This case highlights the rare but life-threatening systemic toxicity associated with soluble barium salts and the importance of considering toxicologic etiologies in trauma patients presenting with unexplained neurological collapse."

People with thymidine kinase 2 deficiency experience progressive myopathy, bulbar weakness and respiratory insufficiency, often losing the ability to walk, eat and breathe independently. Doxecitine and doxribtimine represents the first approved treatment for patients with thymidine kinase 2 deficiency with age of symptom onset \u226412 years by the US Food and Drug Administration and the European Medicines Agency; previously, disease management was limited to supportive care. We investigated the efficacy and safety of pyrimidine nucleos(t)ide therapy in thymidine kinase 2 deficiency. Patients treated with pyrimidine nucleos(t)ides were pooled from retrospective (NCT03701568, NCT05017818) and prospective (NCT03845712) studies and company-supported Expanded Access Programs. Untreated patients were pooled from literature reviews and a retrospective chart review study (NCT05017818). Patient subgroups were stratified by age of thymidine kinase 2 deficiency symptom onset (\u226412 years and >12 years). The primary outcome was survival in 50th-percentile matched pairs of treated and untreated patients. Other outcomes included status of developmental motor milestones, ventilatory and feeding tube support, and safety. In total, 218 patients were included (treated: 104; untreated: 114). Baseline demographics and characteristics were comparable between subgroups. Most patients had an age of symptom onset \u226412 years [treated: 82/104 (78.8%); untreated: 93/114 (81.6%)]. In the age-of-symptom-onset-\u226412-years subgroup, restricted mean survival time (95% confidence interval) was 29.2 (28.2, 30.3) years over the 30 years after symptom onset for treated patients and 14.4 (11.1, 17.6) years for untreated patients. Loss of \u22651 acquired motor milestone was more frequent before treatment start than after. Substantially more patients regained \u22651 lost motor milestone after treatment start than before. Ventilatory and feeding support were used across all age-of-symptom-onset subgroups, but some patients reduced or discontinued support after starting treatment and fewer patients initiated support after treatment start than before. Most treatment-emergent adverse events (TEAEs) did not lead to discontinuation. The most frequent TEAE was diarrhoea [43/50 patients (86.0%)], which was generally mild or moderate and resolved with dose reduction. Serious TEAEs occurred in 28/50 patients (56.0%); few were considered to be drug related [4/50 (8.0%)]. In total, 3/67 patients (4.5%) experienced a fatal serious TEAE, which were not considered to be drug related. These findings indicate that pyrimidine nucleos(t)ide therapy improves survival and functional outcomes in people with thymidine kinase 2 deficiency, especially those with age of symptom onset \u226412 years, and has an acceptable safety profile."

When accompanied by additional symptoms such as bulbar palsy, limb weakness, or lethargy, it is termed MFS overlap syndrome. This report describes a male patient diagnosed with MFS overlap syndrome, presenting with ophthalmoplegia, ataxia, bulbar palsy, numbness in both arms, positive GM4 IgG antibodies, a persistent, intractable headache, and a delayed onset of left-sided peripheral facial palsy. The patient had a preceding suspected case of chlamydial pneumonia before symptom onset, and his condition improved significantly following treatment with intravenous immunoglobulin. This case suggests that chlamydial pneumonia might predispose individuals to GBS. Patients with MFS/pharyngeal-cervical-brachial (PCB) overlap syndrome may exhibit atypical symptoms, including persistent, intractable headaches, and delayed peripheral facial paralysis. Atypical symptoms should not delay the diagnosis and treatment of GBS once other conditions have been adequately excluded.

PrimeC is a fixed-dose oral combination of celecoxib and ciprofloxacin designed to target ALS-related mechanisms, including neuroinflammation, iron homeostasis, and dysregulated microRNAs. To evaluate the safety, tolerability, and potential efficacy of PrimeC in people living with ALS. This was a randomized, double-blind, placebo-controlled, phase 2b trial conducted at 4 ALS referral centers from May 2022 to November 2023 and followed by 12-month open-label extension. Adults with definite or probable ALS and disease duration of 30 months or less were eligible. Of 73 screened, 69 were randomized and 68 were included in the intent-to-treat population. Participants were randomized 2:1 to receive PrimeC or placebo for 6 months, followed by open-label extension PrimeC for all. The primary outcome was safety and tolerability. The prespecified primary biomarker outcome was plasma neuron-derived-exosomal TAR DNA-binding protein 43 (TDP-43) or prostaglandinJ2. Secondary outcomes included change in ALS Functional Rating Scale-Revised (ALSFRS-R) score at 6 and 18 months, survival, and time-to-composite events. Exploratory biomarkers included neurofilament light chains, iron-regulatory proteins, and circulating microRNAs. The 68 participants were well balanced in age at entry and sex. In the PrimeC group, the mean (SD) age was 59.1 (9.1) years, and 27 of 45 participants were male. In the placebo group, the mean (SD) age was 55.0 (13.0) years, and 14 of 23 participants were male. PrimeC was well tolerated, with a safety profile comparable to placebo (adverse event rate, 66.7% PrimeC vs 65.2% placebo). Drug-related adverse events were more frequent with PrimeC (20.0% vs 4.3%), mostly mild to moderate, and transient. At month 6, the mean ALSFRS-R difference was 2.23 points between PrimeC and placebo (95% CI, -0.61 to 5.07; P\u2009=\u2009.12). At month 18, ALSFRS-R scores in participants continuously treated with PrimeC maintained a difference (7.92 points; 95% CI, 2.25 to 13.60; P\u2009=\u2009.007), with significant bulbar difference (3.18 points; 95% CI, 1.32 to 5.04; P\u2009=\u2009.001). Continuous treatment was associated with lower risk of ALS complications, including hospitalization, respiratory failure, or death (HR, 0.36; 95% CI, 0.15-0.85; P\u2009=\u2009.02). In the double-blind period, transferrin levels were preserved with PrimeC (1.90 \u03bcmol/L difference; P\u2009=\u2009.03), the negative ferritin-ALSFRS-R correlation observed in placebo (\u03c1\u2009=\u2009-0.50; P\u2009=\u2009.02) was abolished, and ALS-associated microRNAs were downregulated (log2 fold change: miR-199a-3p, -1.87; false discovery rate [FDR] P\u2009=\u2009.004; miR-199a-5p, -2.23; FDR P\u2009<\u2009.001; miR-181a-5p: -1.89; FDR P\u2009=\u2009.001; miR-181b-5p, -1.62; FDR P\u2009=\u2009.005). Prespecified neuron-derived exosome TDP-43/PgJ2 analyses will be reported separately following completion of development and analyses. PrimeC was safe and well tolerated over 18 months.

ALS patients with bulbar weakness often suffer from troublesome sialorrhea. Botulinum toxin injection, as a neuromuscular blocker, has been widely used in the treatment of sialorrhea. This paper evaluates the safety and efficacy of botulinum toxin injections for the treatment of sialorrhea in ALS patients through a systematic review and meta-analysis. METHODS: A systematic review and meta-analysis was conducted by searching eight databases, including PubMed, EMBASE, and CNKI, up to April 13, 2025. Eligible randomized controlled trials and quasi-experimental studies were analyzed using Review Manager 5.4 and Stata software. RESULTS: Thirteen studies (2 RCTs, 11 quasi-experimental studies) with 130 ALS patients were included. Botulinum toxin significantly reduced sialorrhea and improved quality of life (Z\u2009=\u200910.98, p\u2009<\u20090.00001; RD\u2009=\u20090.82, 95% CI: 0.67\u20130.97).

CONCLUSION: Botulinum toxin appears to be a safe and effective option for managing sialorrhea in ALS patients, regardless of injection technique. However, given that most included studies were observational, further validation through high-quality RCTs is warranted.

Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS."

Recent literature emphasizes a pivot toward objective, non-invasive assessment and targeted, rapid-acting immunomodulation. Advanced diagnostic pipelines now utilize quantitative markers to identify subclinical bulbar involvement, while therapeutic landscapes have expanded to include agents that provide rapid relief in crisis scenarios. These developments represent a departure from purely supportive management toward precision-based neurological intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Efgartigimod and ravulizumab have transitioned into roles as effective bridging or rescue strategies for severe, refractory MG bulbar crisis.\n*   Objective sEMG protocols enable the detection of subclinical bulbar decline, providing a measurement-based framework that is resistant to cognitive-linguistic confounders.\n*   Smartphone-based deep learning (U-Net++ models) offers a scalable, low-barrier diagnostic interface for quantifying tongue motor dysfunction in ALS.\n*   Pyrimidine nucleoside replacement therapy has fundamentally altered the prognosis for infantile-onset TK2 deficiency, enabling milestone recovery previously deemed impossible.\n*   The prevalence of sialorrhea in ALS bulbar-onset cases is increasingly managed through botulinum toxin injection regardless of specific injection technique.\n*   The concept of \"dying back\" of UMN axons in ALS has been refined, with imaging indicating degeneration stops at the brainstem, sparing cortical motor neurons.\n*   The use of PSQI scores to assess sleep quality provides an independent prognostic indicator for bulbar-onset MG and short-term clinical outcomes.\n*   Barium toxicity represents a rare mimic of GBS-like bulbar paralysis, emphasizing the necessity of toxicological screening in unexplained acute paralysis.\n*   Dynamic chest MRI and ultrasound serve as critical objective surrogates for pulmonary function tests in patients where bulbar involvement precludes traditional spirometry.\n*   The presence of LRP4 antibodies characterizes a unique, rare subset of MG coexisting with demyelinating neuropathy, requiring specialized diagnostic panels.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

In children, it typically follows infection, but association with malaria is rare. We report a four\u2011year\u2011old Lebanese girl living in Nigeria, who developed progressive weakness, dysphagia, inspiratory stridor, and gait ataxia 2\u00a0weeks after treatment for Plasmodium falciparum malaria. Neurological examination revealed lower\u2011extremity weakness with areflexia, bulbar involvement causing stridor, unilateral facial weakness, and gait ataxia (Hughes score 4). Cerebrospinal fluid analysis showed albumin\u2011cytologic dissociation, and nerve conduction studies demonstrated acute inflammatory demyelinating polyradiculoneuropathy. Given the rapid progression and severity, therapeutic plasma exchange (PE) was administered (five exchanges over 10\u00a0days) along with supportive care. Strength improved steadily, and at 1\u00a0month she was able to walk and run independently (Hughes score 0). This case expands the limited pediatric literature on malaria-associated GBS and highlights the importance of recognizing evolving bulbar and neurological symptoms after Plasmodium falciparum infection. Early supportive care and immunotherapy may contribute to favorable neurological recovery.\n\nID: 42316955\nTitle: Postinfectious polyneuritis cranialis: A case report.\nAbstract: Polyneuritis cranialis is characterized by the simultaneous or sequential inflammation of multiple cranial nerves, which may occur unilaterally or bilaterally. Although it is often related to infection, its exact etiology remains unclear. Due to its nonspecific clinical manifestations, diagnosis typically relies on the exclusion of other conditions. Herein, we report a case of postinfectious polyneuritis cranialis. The patient presented to our hospital with restricted mouth opening, dysphagia, coughing while drinking, dysarthria, and posterior neck pain following a finger injury. Laboratory tests showed markedly elevated inflammatory markers. Neurological examination revealed involvement of cranial nerves V, IX, X, and XII. Motor nerve conduction studies of the facial nerve suggested partial facial nerve damage. Brain magnetic resonance imaging demonstrated mild nonspecific white matter changes. After exclusion of alternative diagnoses, the patient was diagnosed with polyneuritis cranialis. The patient's condition improved following corticosteroid pulse therapy and was subsequently discharged. This case highlights that the diagnosis of polyneuritis cranialis remains one of exclusion and is often clinically challenging. When encountering patients with rapidly progressive cranial nerve palsies, polyneuritis cranialis should be included in the differential diagnosis after more common structural or systemic etiologies have been excluded.\n\nID: 42293075\nTitle: Efficacy observation of electromyography-guided targeted injection of swallowing muscles for treating dysphagia resulting from medullary paralysis.\nAbstract: To observe the clinical efficacy of electromyography (EMG)-guided targeted mecobalamin injections for treating dysphagia resulting from medullary paralysis and to investigate effective dysphagia management strategies. This study was a prospective randomized controlled trial. A total of 110 patients with dysphagia due to post-stroke bulbar palsy were enrolled at Baoding No.1 Central Hospital from February 2017 to December 2020. Patients were randomly assigned using a random number table to either a control group (n = 55) receiving conventional pharmacotherapy combined with rehabilitation training, or a treatment group (n = 55) receiving the same conventional therapy plus additional EMG-guided targeted injections of mecobalamin into the swallowing muscles. Swallowing function was assessed using the Wada water swallowing test (WST) and videofluoroscopic swallowing study (VFSS) after 2 weeks of treatment. The treatment group showed a significantly higher overall response rate on the WST than the control group (P < 0.05). Based on VFSS, the marked and overall effectiveness rates were 50.9% and 96.4% in the treatment group, respectively, significantly higher than the corresponding rates of 18.2% and 83.6% in the control group (both P < 0.05). The incidence of aspiration decreased significantly in both groups post-treatment (P < 0.05), with a more pronounced reduction observed in the treatment group (P < 0.05). EMG-guided targeted injection of mecobalamin into swallowing muscles is an effective adjunctive strategy for enhancing swallowing function in patients with dysphagia due to post-stroke medullary paralysis.\n\nID: 42263764\nTitle: Characteristics and Outcomes of Guillain-Barr\u00e9 Syndrome in Children.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is one of the leading causes of acute paralysis in children. Our aim was to describe the clinical characteristics, paraclinical features, and recovery outcomes of children with GBS. This is a prospective study of 40 children diagnosed with GBS from January 2021 to December 2022. Data on demographics, clinical features, treatments, complications, and outcomes were collected at follow-up time points based on the Guillain-Barr\u00e9 disability score (GDS). In the study of 40 children, the number of male children with GBS was predominant (82.5%), and more than 50% of GBS patients were older than 10 years. Seventy-five percent of patients with GBS had a preceding infection, with respiratory tract infections being the most common. The most common initial symptom was leg pain. Bulbar palsy was observed in 47.5% of patients and was a relatively frequent clinical feature in our cohort. Albuminocytological dissociation (ACD) rate within the first 7 days was 73.3%. Based on nerve conduction study results, the phenotypes were distributed as follows: acute inflammatory demyelinating polyneuropathy (AIDP) accounted for 55%; acute motor-sensory axonal neuropathy (AMSAN) for 17.5%; acute motor axonal neuropathy (AMAN) for 10%; inexcitable nerves for 5%; and unclassifiable cases for 12.5%. At the 6-month follow-up, 100% of pediatric patients achieved independent ambulation. Furthermore, a correlation was found between mechanical ventilation and GDS at 1 and 2 months; however, no association was observed at 3 and 6 months' postonset. In pediatric GBS, the most common initial manifestations are limb pain and paresthesia. Most patients achieve good recovery; the need for mechanical ventilation is associated with bulbar weakness, facial paralysis, pneumonia, and severe initial limb weakness.\n\nID: 41907206\nTitle: ANCA-Associated Vasculitis with Predominant Peripheral and Central Nervous System Involvement: A Case Report.\nAbstract: ANCA-associated vasculitis (AAV) is an immune-mediated multi-system disease. It can present with neurological involvement as its predominant manifestation. We report a case of AAV with predominant peripheral and central nervous system involvement. A 62-year-old male presented with fever and asymmetric weakness and pain in the lower limbs. Electrophysiological studies revealed asymmetric axonal damage in both lower limbs. During hospitalization, he developed acute bulbar palsy. Brain MRI confirmed bilateral basal ganglia infarction. Ancillary tests indicated involvement of the lungs, kidneys, and hematological systems, along with positive MPO-ANCA (p-ANCA), confirming the diagnosis of AAV. His symptoms gradually improved following treatment with glucocorticoids and immunosuppressants. At the 6-month follow-up, his symptoms were largely resolved. The presence of asymmetric axonal neuropathy or atypical non-atherosclerotic cerebral infarction, particularly when accompanied by multisystem involvement, should raise suspicion for AAV. Early diagnosis and prompt treatment significantly improve patient outcomes.\n\nID: 41820266\nTitle: An Unusual Presentation of Juvenile Amyotrophic Lateral Sclerosis with Superoxide Dismutase 1 Mutation: Subacute Bulbar Palsy With Asymmetric Limb Weakness.\nAbstract: \n\nID: 41795250\nTitle: Deciphering the Breathless Future: A Novel Approach to Predicting Respiratory Failure in Children With Guillain-Barr\u00e9 Syndrome.\nAbstract: The applicability and utility of clinical predictive models for respiratory failure in the pediatric Guillain-Barr\u00e9 syndrome (GBS) and Asian population are significantly constrained. Therefore, we aim to develop and validate a clinical prediction model to predict respiratory failure risk in pediatric GBS patients in China, alongside the economic immunological biomarkers in decision-making, and evaluate the Erasmus GBS Respiratory Insufficiency Score (EGRIS)-Kids score's efficacy. The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation.\n\nID: 41782152\nTitle: Effects of ultrasound-guided stellate ganglion block in poststroke bulbar palsy: a double-blind placebo-controlled trial.\nAbstract: Bulbar palsy typically causes severe dysphagia. Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov.

METHODS: Our study analyzed clinical factors linked to pneumonia in GBS patients through a retrospective review of 101 individuals admitted to Tianjin Huanhu Hospital between January 2020 and December 2023. Patients were divided into two groups based on pneumonia development after admission: GBS with pneumonia (n\u2009=\u200919) and GBS without pneumonia (n\u2009=\u200982). Clinical and blood parameters were compared between the groups. Logistic regression analysis identified predictive factors for pneumonia in these GBS patients. RESULTS: Significant associations were found between pneumonia and older age (P\u2009=\u20090.01), bulbar palsy (P\u2009=\u20090.017), mechanical ventilation (MV) support (P\u2009<\u20090.01), hypoalbuminemia (P\u2009<\u20090.01), hyponatremia (P\u2009<\u20090.01), and underlying conditions (P\u2009=\u20090.008). Multivariate logistic regression identified bulbar palsy, MV support and hyponatremia as significant independent risk factors for pneumonia. Finally, GBS patients with pneumonia experienced longer hospital stays and worse functional outcomes. CONCLUSIONS: We initially identified key risk factors for pneumonia in GBS, highlighting its association with poorer prognoses.\n\nID: 41592980\nTitle: Tongue atrophy following unexplained nausea, vomiting, and hiccups.\nAbstract: \n\nID: 41536455\nTitle: A Case of Foix-Chavany-Marie Syndrome with History of Glioblastoma Showing Partial Recovery.\nAbstract: Foix-Chavany-Marie syndrome (FCMS) or bilateral opercular syndrome (OPS) is a rare pseudobulbar palsy characterized by facial, lingual, pharyngeal, and masticatory voluntary muscle paralysis resulting in anarthria with preservation of autonomic, involuntary, and reflexive functions. Damage to the posterior part of the inferior frontal gyrus and inferior part of precentral gyrus play a role in the pathogenesis of FCMS. We report a rare case of bilateral OPS following an acute right middle cerebral artery (MCA) infarct in a patient with history of glioblastoma, and resection in the left MCA territory within the cingulate gyrus, showing recovery of speech and swallowing despite intensive bilateral opercular lesions owing to extensive multidisciplinary team support. However, the patient was discharged with a percutaneous endoscopic gastrostomy tube for long-term enteral feeding support due to partial recovery. The patient's history of glioblastoma, left MCA cingulate gyrus resection and right MCA infarction with automatic-voluntary dissociation led to the diagnosis of FCMS. Rehabilitation surprisingly showed mild improvement in speech and swallowing despite extensive bilateral opercular lesions proving that there are still chances of improvement in speech and swallowing in OPS with the right multidisciplinary approach. Patients with a history of brain tumours like glioblastoma can develop bilateral OPS later in life in case of other vascular events that cause lesions in a previously unaffected operculum, triggering symptoms. Extensive involvement of the speech and language team is of significant in the management of FCMS cases as above where some recovery might still be seen. Foix-Chavany-Marie syndrome (FCMS) can be caused by bilateral opercular lesions (new or old or a combination of both) in patients with history of high-grade brain tumours.Patients with bilateral opercular syndrome experience full or partial or no recovery at all of speech and swallowing, hence proper rehabilitation with a Speech and Language Team is significant.Understanding automatic-voluntary dissociation in FCMS and being able to differentiate it from bulbar palsy and other similar phenomena is crucial in making a diagnosis of FCMS.\n\nID: 41517538\nTitle: Establishing Diagnostic and Differential Diagnostic Criteria for Amyotrophic Lateral Sclerosis.\nAbstract: Motor neuron disease (MND) represents a broad and heterogeneous group of disorders involving the upper or lower motor neurons, represented mainly by amyotrophic lateral sclerosis (ALS), primary lateral sclerosis (PLS), progressive muscular atrophy (PMA) and progressive bulbar palsy (PBP). Primary motor neuronopathies are characterized by progressive degenerative loss of anterior horn cell motoneurons (lower motor neurons) or loss of giant pyramidal Betz cells (upper motor neurons). Rare atypical variants of MND-ALS include flail arm syndrome (FA), flail leg syndrome (FL), facial-onset sensory and motor neuronopathy (FOSMN), finger extension weakness and downbeat nystagmus motor neuron disease (FEWDON-MND) and long-standing and juvenile MND-ALS. In this article, we present a review of diagnostic criteria and the differential diagnosis for MND, focusing on ALS.\n\nID: 41513898\nTitle: Heterogeneous phenotype and cardiovascular comorbidities in Swedish patients with spinobulbar muscular atrophy.\nAbstract: Spinobulbar muscular atrophy (SBMA) is an X-linked neuromuscular disorder characterized by adult-onset progressive muscle atrophy, flaccid paresis, and bulbar palsy. In addition, increasing evidence indicates that SBMA is a multisystem disorder with prominent non-motor symptoms, such as sensory neuropathy, androgen insensitivity, and glucose intolerance. This study aimed to further characterize the clinical manifestations and biomarker profile in a large Swedish SBMA cohort. 49 genetically confirmed SBMA patients were identified from a motor neuron disease database at Ume\u00e5 University Hospital, Sweden. CAG repeat length in the androgen receptor (AR) gene was assessed by RP-PCR. Blood samples were analyzed for cardiovascular and muscle biomarkers. Clinical data were collected from medical records and interviews, with autopsy findings reviewed in two cases. The mean CAG repeat length was 43.1, with a mean age at motor symptom onset of 58.6\u00a0years. Notably, 19% of patients initially presented with sensory symptoms. High prevalence of hypertonia (70%), diabetes mellitus (39%), and cardiac disease (38%) was observed. Elevated troponin levels were common, and pNfL (neurofilament light chain in plasma) was elevated in seven patients, likely reflecting combined cerebrovascular and cardiovascular comorbidity. Importantly, two of these seven patients exhibited rapid disease progression, and a concomitant diagnosis of ALS was confirmed histopathologically. This cohort was characterized by a relatively low number of AR gene CAG repeats and a late onset of motor symptoms. Sensory symptoms frequently occurred before motor decline. Cardiovascular disease and diabetes were common comorbidities and, in some cases, preceded neurological symptoms. These findings underscore the need for improved clinical awareness of the heterogeneous presentation of SBMA and support routine cardiovascular monitoring to reduce diagnostic delays and prevent early mortality.\n\nID: 41473789\nTitle: Bulbar Manifestation of Myasthenia Gravis Initially Attributed to Goiter: A Case Report.\nAbstract: \n\nID: 41355085\nTitle: [Duchenne de Boulogne: Pioneer of Neurology].\nAbstract: Guillaume-Benjamin-Amand Duchenne de Boulogne once remarked that he found neurology \"a sprawling infant of unknown parentage, which he succored to lusty youth.\" He was born in the Boulogne-sur-Mer region of France in1806. He studied medicine in Paris from 1826 to 1831 and later established a practice in Boulogne. In 1835, he observed isolated muscular contractions produced by electropuncture and began investigating the electrical excitation of muscle. In 1842, he left Boulogne for Paris to continue medical research, often visiting hospitals with his electrical equipment to examine unusual cases. He was an inventive investigator who developed several technical innovations, including electrodiagnosis, electrotherapy, needle muscle biopsy, and medical photography. He enumerated his major discoveries in \"L'Electrisation Localisee,\" which included descriptions of progressive muscular atrophy (now called spinal muscular atrophy), atrophic paralysis of childhood (poliomyelitis), progressive locomotor ataxia (tabes dorsalis), glosso-labio-laryngeal paralysis (progressive bulbar palsy), and pseudohypertrophic paralysis (Duchenne muscular dystrophy). Based on Duchenne's intensive investigations, Jean-Martin Charcot refined his medical concepts and established nosological disease entities, calling Duchenne \"mon ma\u00eetre en neurologie\" (my master in neurology). Duchenne never held a hospital or university position. He died of cerebrovascular disease on September 17, 1875.\n\nID: 41328116\nTitle: An Atypical Descending Variant of Guillain-Barr\u00e9 Syndrome With Bulbar Palsy, Autonomic Instability, and Delayed Colonic Pseudo-Obstruction: A Case Report.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is an acute, immune-mediated polyradiculoneuropathy that is the most common cause of acute flaccid paralysis worldwide. The classical form manifests as an ascending, symmetrical weakness, but atypical variants, including descending presentations, have been increasingly recognized. Such variants often pose diagnostic challenges and are associated with more severe disease and prolonged recovery. We describe a 70-year-old woman with well-controlled hypertension who presented with progressive dysphagia, pooling of saliva, and upper limb weakness. Clinical examination revealed bulbar dysfunction, areflexia in the upper limbs, and motor power in the upper limbs was markedly reduced to grade 1/5 on the Medical Research Council (MRC) scale, while lower limb strength was preserved. Within hours of admission, the weakness progressed to quadriplegia with respiratory distress, necessitating intubation and mechanical ventilation. Cerebrospinal fluid analysis demonstrated albumin cytological dissociation, and nerve conduction studies revealed changes consistent with GBS. Intravenous immunoglobulin was initiated but discontinued due to anaphylaxis; therapeutic plasma exchange was subsequently performed. The patient had marked cardiovascular lability and, after one month, acute colonic pseudo-obstruction (ACPO), which resolved with conservative management. Around the 40th day, she experienced complete left lung collapse due to mucus plugging, which was successfully managed with bedside bronchoscopy. Persistent bulbar dysfunction delayed decannulation until day 80. Remarkably, full neurological recovery was achieved only after six months of follow-up. This case highlights several atypical and severe features of GBS: descending onset with bulbar involvement at presentation, multisystem autonomic dysfunction extending to the gastrointestinal tract, and a protracted course despite early immunotherapy and supportive care. The unusually delayed onset of ACPO and persistent bulbar palsy underscores the need for vigilance beyond the acute phase. Hence, clinicians should maintain a high index of suspicion for atypical variants of GBS in patients with acute, progressive weakness, even when the presentation deviates from the classical ascending pattern. A structured, multimodal diagnostic approach and timely initiation of therapy are essential to prevent complications. Severe variants may follow a prolonged recovery trajectory, requiring sustained multidisciplinary management.\n\nID: 41295274\nTitle: Riboflavin Transporter Deficiency as a Cause of Progressive Encephalopathy.\nAbstract: Background/Objective: Riboflavin transporter deficiency (RTD) is a rare neurodegenerative disease, with under 500 cases genetically confirmed since the early 2000s. Thus far, three separate subtypes of RTD2 are described-type 1, 2 and 3-but, previously, RTD was classified as two separate genetic defects: Brown-Vialetto-Van Laere syndrome and Fazio-Londe syndrome, caused by mutations in the SLC52A2 and SLC52A3 genes, respectively. The most prominent symptoms found in patients include encephalopathy, expressed as peripheral and cranial nerve neuropathy, which in turn lead to a series of complications: decreased muscle strength, hypotonia, visual impairment, sensorineural hearing loss, bulbar palsy, sensory ataxia and respiratory insufficiency secondary to diaphragmatic paresis. At the cellular level, riboflavin is modified into active flavin cofactors: FMN, mediating riboflavin phosphorylation through riboflavin kinase, and FAD, involved in FMN adenylation through the flavin dinucleotide 1 synthesis. FMN and FAD are two of approximately 100 proteins collectively described as the 'flavoproteome'. Most of them are mitochondrial oxidoreductases, catalyzing the electron transport in many metabolic reactions, as well as regulating important cell processes, such as the production of reactive oxygen species, protein conformation and damage repair. FMN and FAD are also responsible for the conversion of B6 and B9 vitamins into their active forms, which allows for healthy cell growth and immune function. Methods: In this article, the authors describe two children, a 6-year-old girl and her 5-year-old sister, both presenting with RTD2 caused by mutations in the SLC52A2 gene (c.916G>C (p.Gly306Arg); c.477C>G (p.Cys159Trp)), in whom the disease progression was successfully inhibited by vitamin B2 supplementation in varying doses. Results: Their clinical image consists of psychomotor developmental delay, ataxia, horizontal nystagmus, hearing loss and a lack of visual fixation. Conclusions: The phenotype and clinical signs presented by the described sisters are further discussed in relation to the previously published reports of RTD2 cases.\n\nID: 41241894\nTitle: Rapid Bolus Inflow into the Esophagus in a Patient with a Tracheostomy after Surgical Treatment for Dysphagia.\nAbstract: This report describes a case in which a patient with an open tracheostomy, following surgery for severe dysphagia, acquired vacuum swallowing and exhibited rapid bolus inflow into the esophagus. A 39-year-old man with bulbar palsy caused by medullary surgery demonstrated impaired pharyngeal contraction and upper esophageal sphincter opening. After undergoing laryngeal suspension and cricopharyngeal myotomy, videofluoroscopic evaluation of swallowing revealed rapid passage of the bolus from the pharynx into the esophagus. High-resolution manometry demonstrated markedly negative intraesophageal pressure accompanied by simultaneous elevation of lower esophageal sphincter pressure during swallowing. These findings suggest that the patient had spontaneously acquired vacuum swallowing despite the presence of a tracheostoma communicating with the atmosphere. Recognition of this compensatory mechanism is important because it may facilitate bolus transport in individuals with tracheostomy. Increased awareness of this swallowing pattern may prevent underdiagnosis and offer new insights into rehabilitation strategies for dysphagia.\n\nID: 41215519\nTitle: Internal Ophthalmoplegia and Bulbar Palsy: A Rare Case Report on the Atypical Presentation of Miller-Fisher Syndrome.\nAbstract: The eponym \"Landry Guillain-Barre syndrome\" encompasses a wide spectrum of disorders characterized by acute-onset immune-mediated polyneuropathies. Some variants are associated with seropositivity for antibodies against GQ1b ganglioside, and are characterized by ophthalmoplegia, ataxia, and areflexia. We present a case of atypical Miller Fisher syndrome in a 26-year-old female who presented with pupillary involvement along with external ophthalmoplegia, bulbar palsy, and appendicular and axial ataxia.\n\nID: 41090254\nTitle: A Case of Miller-Fisher Overlap Syndrome With Positive Anti-GM4 Antibody and Atypical Symptoms.\nAbstract: Miller-Fisher syndrome (MFS) is a recognized clinical variant of Guillain-Barr\u00e9 syndrome (GBS), characterized by the classic triad of ophthalmoplegia, ataxia, and areflexia. When accompanied by additional symptoms such as bulbar palsy, limb weakness, or lethargy, it is termed MFS overlap syndrome. This report describes a male patient diagnosed with MFS overlap syndrome, presenting with ophthalmoplegia, ataxia, bulbar palsy, numbness in both arms, positive GM4 IgG antibodies, a persistent, intractable headache, and a delayed onset of left-sided peripheral facial palsy. The patient had a preceding suspected case of chlamydial pneumonia before symptom onset, and his condition improved significantly following treatment with intravenous immunoglobulin. This case suggests that chlamydial pneumonia might predispose individuals to GBS. Patients with MFS/pharyngeal-cervical-brachial (PCB) overlap syndrome may exhibit atypical symptoms, including persistent, intractable headaches, and delayed peripheral facial paralysis. Atypical symptoms should not delay the diagnosis and treatment of GBS once other conditions have been adequately excluded. The presence of anti-GM4 antibodies, often found alongside other anti-ganglioside antibodies, may serve as a critical immunological factor in MFS/PCB overlap syndrome.\n\nID: 41063391\nTitle: Familial ALS With p. L127S (L126S) Variant of the Cu/Zn SOD1 Gene: A Report of Two New Cases and Literature Review.\nAbstract: Herein, we report two autopsy cases of familial ALS with a p. L127S (L126S) SOD1 variant. Case 1 involved a 62-year-old woman who presented with lower-extremity muscle weakness with lower motor neuron signs. The patient developed bulbar palsy and died of respiratory failure 9\u2009years after onset. Case 2 (the second son of Case 1) presented with lower-extremity muscle weakness at the age of 38\u2009years, with upper and lower motor neuron signs and died of respiratory failure 8\u2009years after onset. The pathological findings in both cases predominantly consisted of lower motor neuron loss and degeneration of the lateral and posterior funiculi. Numerous conglomerate hyaline inclusions (CHIs) were observed in the remaining motor neurons. Vacuole formation was observed inside the inclusions, sometimes with granular structures. Some inclusions were positive for ubiquitin, p62, and SOD1. Electron microscopy revealed that CHIs were composed of neurofilaments and expanded mitochondria. By literature review, ALS with p. L127S disclosed a male-dominant incidence rate, a variety of ages at onset, and low penetrance. The initial symptom was exclusively lower limb weakness. One-third of the patients only showed lower motor neuron signs and half did not present with bulbar symptoms. The neuropathological findings commonly observed in ALS with p. L127S variants were mainly the degeneration of lower motor neurons and the sensory system, including the posterior column, Clarke's nucleus, and the associated cerebellar system. The formation of intracytoplasmic hyaline inclusions was also a prominent feature. ALS with p. L127S variant should be included in the possible diagnosis of slowly progressive muscle weakness in the lower extremities, with or without family history or upper motor neuron signs. The loss of lower motor neurons and the accumulation of neurofilaments in the remaining neurons are key to the pathological diagnosis for ALS with p. L127S variant.\n\nID: 41004918\nTitle: Tongue shear wave elastography for bulbar dysfunction in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often manifests with tongue involvement, leading to dysarthria and dysphagia. While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS.\n\nID: 40977954\nTitle: Post-Marketing Safety Concerns with Efgartigimod alfa: A Pharmacovigilance Analysis Based on the Food and Drug Administration Adverse Event Reporting System Database.\nAbstract: Efgartigimod alfa (EA) is a novel US Food and Drug Administration (FDA) approved neonatal Fc receptor-targeting drug; however, its real-world adverse event (AE) profile remains underexplored. AE reports primarily related to EA were retrieved from the US FDA Adverse Event Reporting System database for the fourth quarter of 2021 to the third quarter of 2024. Disproportionality analysis using Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network, and Multi-item Gamma Poisson Shrinker algorithms was employed to detect signals of AEs. Our study processed 3,182 AE reports related to EA, revealing 57 signals that met the criteria of the ROR, PRR, Bayesian Confidence Propagation Neural Network, and Multi-item Gamma Poisson Shrinker algorithms across 14 system organ classes. Notably, the most significant signal in the System Organ Class was \"Surgical and medical procedures\", whereas the most significant signal in Preferred Term was \"Bulbar Palsy\". Some unexpected over-the-counter AEs, including falls, choking, sepsis, nephrolithiasis, and atrial fibrillation, were also observed. The median onset time of EA-related AEs was 101.5 d (interquartile range 27-260). The AE risk model associated with EA should be referred to as \"early failure\", with the likelihood of AEs decreasing over time. This study highlights the potential AEs and risks associated with the clinical use of EA; the analysis provides significant evidence regarding the clinical safety of EA.\n\nID: 40966487\nTitle: Teaching NeuroImage: Gelsolin Amyloidosis: A Cause of Familial Progressive Facial and Bulbar Palsy.\nAbstract: \n\nID: 40962541\nTitle: [Clinical analysis of anti-GT1a antibody-positive Guillain-Barr\u00e9 syndrome in 25 children].\nAbstract: Objective: To summarize the clinical characteristics, treatment, and prognosis of children with anti-GT1a antibody-positive Guillain-Barr\u00e9 syndrome (GBS). Methods: A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children's Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results: A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71\u00b18) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23\u00b13) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge (Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions: Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment. \u76ee\u7684\uff1a \u603b\u7ed3\u513f\u7ae5\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u7684\u4e34\u5e8a\u7279\u70b9\u3001\u6cbb\u7597\u53ca\u9884\u540e\u3002 \u65b9\u6cd5\uff1a \u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\uff0c\u9009\u62e92019\u5e743\u6708\u81f32024\u5e7412\u6708\u5728\u5e7f\u5dde\u533b\u79d1\u5927\u5b66\u9644\u5c5e\u5987\u5973\u513f\u7ae5\u533b\u7597\u4e2d\u5fc3\u795e\u7ecf\u5185\u79d1\u4e34\u5e8a\u8bca\u65ad\u4e3a\u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u768425\u4f8b\u60a3\u513f\uff0c\u6536\u96c6\u5e76\u5206\u6790\u5176\u4e34\u5e8a\u8d44\u6599\u53ca\u6cbb\u7597\u968f\u8bbf\u8d44\u6599\u3002\u91c7\u7528Mann-Whitney U\u68c0\u9a8c\u6bd4\u8f83\u60a3\u513fHughes\u529f\u80fd\u5206\u7ea7\u8bc4\u5206\uff08HFGS\uff09\u53d8\u5316\u3002 \u7ed3\u679c\uff1a 25\u4f8b\u60a3\u513f\u753712\u4f8b\u3001\u597313\u4f8b\uff0c\u9996\u6b21\u53d1\u75c5\u5e74\u9f84\u4e3a\uff0871\u00b18\uff09\u6708\u9f84\u300216\u4f8b\uff0864%\uff09\u6709\u524d\u9a71\u611f\u67d3\uff0c\u5176\u4e2d13\u4f8b\u4e3a\u547c\u5438\u9053\u611f\u67d3\u3002\u75be\u75c5\u9ad8\u5cf0\u65f6\u795e\u7ecf\u7cfb\u7edf\u75c7\u72b6\u5305\u62ec\u80a2\u4f53\u65e0\u529b21\u4f8b\uff0884%\uff09\u3001\u7403\u9ebb\u75f913\u4f8b\uff0852%\uff09\u3001\u55dc\u77617\u4f8b\uff0828%\uff09\u3001\u80a2\u4f53\u75bc\u75db9\u4f8b\uff0836%\uff09\u3001\u5171\u6d4e\u5931\u8c036\u4f8b\uff0824%\uff09\u3001\u547c\u5438\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u773c\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u5355\u4fa7\u9762\u795e\u7ecf\u9ebb\u75f94\u4f8b\uff0816%\uff09\u300223\u4f8b\u60a3\u513f\u8111\u810a\u6db2\u68c0\u67e5\uff0c\u86cb\u767d-\u7ec6\u80de\u5206\u79bb18\u4f8b\u300225\u4f8b\u60a3\u513f\u5168\u810a\u67f1\u78c1\u5171\u632f\u6210\u50cf\uff08MRI\uff09\u68c0\u67e5\u793a\u810a\u795e\u7ecf\u6839\u5f3a\u531618\u4f8b\uff0c\u67d4\u8111\u819c\u5f3a\u5316\u5408\u5e76\u810a\u795e\u7ecf\u6839\u5f3a\u53161\u4f8b\u300216\u4f8b\u60a3\u513f\u63a5\u53d7\u808c\u7535\u56fe\u68c0\u67e5\uff0c15\u4f8b\u5f02\u5e38\uff0c\u5176\u4e2d\u8131\u9ad3\u9798\u75c5\u53d88\u4f8b\u3001\u8131\u9ad3\u9798\u5408\u5e76\u8f74\u7d22\u75c5\u53d84\u4f8b\uff0c\u8f74\u7d22\u75c5\u53d83\u4f8b\u3002\u9759\u8109\u8f93\u6ce8\u514d\u75ab\u7403\u86cb\u767d\uff08IVIG\uff09\u6cbb\u7597 21\u4f8b\uff0884%\uff09\uff0c\u5176\u4e2d3\u4f8b\u60a3\u513fIVIG\u6cbb\u7597\u540e\u75c5\u60c5\u8fdb\u5c55\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\u884c\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u53ca\u8840\u6db2\u51c0\u5316\u6cbb\u7597\uff0c\u5305\u62ec\u8840\u6d46\u7f6e\u63622\u4f8b\u3001\u514d\u75ab\u5438\u9644\u6cbb\u75971\u4f8b\u30024\u4f8b\u60a3\u513f\u62d2\u7eddIVIG\u6cbb\u7597\u63a5\u53d7\u9759\u8109\u8f93\u6ce8\u7532\u6cfc\u5c3c\u9f99\uff08IVMP\uff09\u6cbb\u7597\uff0c\u5176\u4e2d1\u4f8b\u56e0\u547c\u5438\u808c\u9ebb\u75f9\u63a5\u53d7\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u6cbb\u7597\uff0c\u7ee7\u7eedIVMP\u5e8f\u8d2f\u6cbb\u7597\u540e\u62d4\u9664\u6c14\u7ba1\u63d2\u7ba1\u300225\u4f8b\u60a3\u513f\u9996\u6b21\u53d1\u75c5\u6025\u6027\u671f\u7684\u4f4f\u9662\u65f6\u95f4\u4e3a\uff0823\u00b13\uff09d\uff0c\u51fa\u9662\u65f6HFGS 1.6\uff080.6\uff0c2.7\uff09\u5206\uff0c\u9996\u6b21\u53d1\u75c5\u51fa\u9662\u81f3\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u7684\u65f6\u95f4\u95f4\u9694\u4e3a12\uff084\uff0c18\uff09\u4e2a\u6708\uff0cHFGS 0.1\uff080.0\uff0c0.5\uff09\u5206\uff0c\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u65f6HFGS\u4f4e\u4e8e\u51fa\u9662\u65f6\uff08Z=4.38\uff0cP<0.05\uff09\u30022\u4f8b\u60a3\u513f\u590d\u53d1\uff0c\u518d\u6b21\u4e88IVIG\u6cbb\u7597\u540e\u7f13\u89e3\uff0c\u968f\u8bbf1\u5e74\u672a\u518d\u590d\u53d1\u3002 \u7ed3\u8bba\uff1a \u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u6025\u6027\u671f\u5e38\u89c1\u7684\u75c7\u72b6\u4e3a\u80a2\u4f53\u65e0\u529b\u53ca\u7403\u9ebb\u75f9\uff0c\u4e25\u91cd\u8005\u53ef\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\uff0c\u808c\u7535\u56fe\u4ee5\u8131\u9ad3\u9798\u75c5\u53d8\u591a\u89c1\uff0cMRI\u810a\u795e\u7ecf\u6839\u5316\u5e38\u89c1\uff0c\u591a\u6570\u60a3\u513fIVIG\u514d\u75ab\u6cbb\u7597\u6548\u679c\u826f\u597d\uff0c\u65e0\u4e25\u91cd\u795e\u7ecf\u7cfb\u7edf\u540e\u9057\u75c7\u6b8b\u7559\u3002\u5c11\u6570\u60a3\u513f\u53ef\u80fd\u590d\u53d1\u3002.\n\nID: 40918919\nTitle: Utility of Breath-Holding Time in Monitoring Acute Neuromuscular Respiratory Failure in Bulbar-Onset Myasthenia Gravis: A Case Report.\nAbstract: We report the management of a 64-year-old male with newly diagnosed bulbar-onset myasthenia gravis (MG) who was hospitalized with acute neuromuscular respiratory insufficiency. This case highlights the challenges in monitoring respiratory function in MG patients, especially in the presence of bulbar and nuchal weakness, and emphasizes the potential utility of single breath-hold time (SBHT) over forced vital capacity (FVC) as a reliable bedside monitoring tool. Despite initial stabilization with intravenous immunoglobulin (IVIG), the patient deteriorated, requiring escalation to the intensive care unit (ICU), and the clinical worsening corresponded with the SBHT rather than with FVC.\n\nID: 40913874\nTitle: A case report on Ayurvedic management of progressive bulbar palsy-A rare amyotrophic lateral sclerosis phenotype.\nAbstract: This case report is the description of a devastating illness, Progressive Bulbar Palsy (PBP) of a sixty-seven years old male patient. He presented with complaints of slurred speech, hearing impairment, generalised weakness of limbs, weakened grip to hold objects in hand, difficulty to walk with normal speed, frequent dizzy feeling while walking, severe fatigue, increased anger, heaviness of head, depression, anxiety, decreased memory and headache for 1 year. When he consulted conventional medicine, in Magnetic Resonance Imaging (MRI) of brain, only 'Partial empty sella' and age related mild cerebral atrophy was detected and the patient was diagnosed PBP clinically. They prescribed Riluzole 50 mg tablet twice a day and Fluoxetine 10mg capsules at night time for 3 months, but obtained no relief for symptoms and consulted this Out Patient Department (OPD). In Ayurvedic parlance, PBP resembles conditions like Kaphavruta vata. In this patient, Pittavritavata symptoms like bhrama (\u223cdizziness) was also present in increased severity. Diagnosis was done with the aid of Gold Coast diagnostic criteria. Internal and external medications with properties alleviating avarana (\u223cocclusion) of vata by kapha and pitta, shodhana (\u223cexpelling the aggravated doshas and cleanses the body internally), rejuvenating (Rasayana) properties, for overall strengthening of nervous system and musculoskeletal system, enhancing balance and coordination, improving speech and memory were used. The assessment was done before and after the treatment by 'Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). The score before and after the treatment was 35 and 45 respectively out of 48. The treatment helped to increase the quality of life exceptionally as symptomatic relief was obtained. As it is a devastating disorder with poor prognosis and most probably will lead to death, it is advisable to repeat the treatments in regular intervals, depending on the recurrence of symptoms, if any.\n\nID: 40901171\nTitle: Acquired hemophilia a in a female with minimal change disease and hypothyroidism: a rare case report.\nAbstract: Juvenile amyotrophic lateral sclerosis (J-ALS) is extremely rare neurodegenerative motor neuron disorder that begins in early childhood or adolescence, before the age of 25\u00a0years old. It is characterized by gradual disease progression with comparison to adult-onset ALS and is often linked to genetic mutations. A 16-years-old female presented with long history of generalized weakness since age of 10 years, followed by bilateral sensorineural hearing loss, bulbar symptoms, and limb spasticity. Neurological examination revealed upper motor neuron signs in upper limbs, lower motor neuron signs in lower limbs, and bulbar involvement. Nerve conduction test was normal however, MRI showed early degenerative changes, and diagnosed with J-ALS after careful evaluation. She was started on Riluzole. Despite ICU care and supportive interventions including PEG and tracheostomy, she succumbed to respiratory failure. Rarity, atypical presentation, and finical constraints can delay diagnosis of J-ALS. However, early diagnosis after careful evaluation of clinical symptoms, medical history, electrophysiological and imaging studies followed by prompt treatment with Riluzole and supportive interventions can help prolong survival and improve quality of life. J-ALS is a rare motor neuron disease which possess immense diagnostic challenges, can exhibit relentless progression over short period of time with time.\n\nID: 40825554\nTitle: [Myasthenia Gravis Treated with Zilucoplan Prior to Extended Transsternal Thymectomy for the Prevention of Myasthenic Crisis: A Case Report].\nAbstract: A 50year-old female was diagnosed with myasthenia gravis (MG) following aspiration pneumonia. Despite treatment with prednisolone (5mg/day) and intravenous immunoglobulin (IVIg), the bulbar palsy persisted. Additionally, chest CT revealed findings suggestive of invasive thymoma or thymic carcinoma, leading to a planned thymectomy with median sternotomy. This case presents a high-risk of myasthenic crisis due to thymoma-associated MG, persistent bulbar palsy, and the need for highly invasive surgery. Therefore, enhanced immunotherapy was required to prevent this crisis, and zilucoplan was chosen because of its rapid onset of action and compatibility with IVIg. Following the initiation of zilucoplan, there was prompt improvement in the symptoms of MG. Effective preoperative control of MG led to a good clinical course, with no significant postoperative myasthenic crisis or exacerbation of symptoms. This is the first report on the use of zilucoplan for the prevention of perioperative myasthenic crisis.

ALS pathology primarily involves the failure of protein quality control mechanisms, leading to the accumulation of misfolded proteins, particularly TAR DNA-binding protein 43 (TDP-43). TDP-43 aggregation is a central pathological feature of ALS. Maintaining protein homeostasis is critical and facilitated by heat shock proteins (HSPs), particularly the HSP40 family, which includes co-chaperones such as DNAJC7. Here, we report a family with three siblings affected by ALS who carry a homozygous c.518dupC frameshift variant in DNAJC7, a member of the HSP40 family. All three patients exhibited progressive muscle weakness, limb atrophy, bulbar palsy, and respiratory failure. Pathological examination revealed degeneration of both upper and lower motor neurons, with phosphorylated TDP-43-positive neuronal cytoplasmic inclusions in the frontal and temporal cortices. Immunoblot analysis were consistent with a type B pattern of phosphorylated TDP-43 in the precentral gyrus. Immunohistochemistry and RNA sequencing analyses demonstrated a substantial reduction in DNAJC7 expression at both the protein and RNA levels in affected brain regions. In a TDP-43 cell model, DNAJC7 knockdown impaired the disassembly of TDP-43 following arsenite-induced stress, whereas DNAJC7 overexpression suppressed the assembly and promoted the disassembly of arsenite-induced TDP-43 condensates. Furthermore, in a zebrafish ALS model, dnajc7 knockdown resulted in increased TDP-43 aggregation in motor neurons and reduced survival. To the best of our knowledge, this study provides the first evidence linking biallelic loss-of-function variants in DNAJC7 to familial ALS with TDP-43 pathology.\n\nID: 40764927\nTitle: Rhombencephalitis associated with varicella-zoster virus masquerading as Guillain-Barr\u00e9 syndrome.\nAbstract: Although rare, rhombencephalitis or inflammation of the brainstem and cerebellum has significantly associated morbidity and mortality. We describe the case of a 64-year-old previously healthy, immunocompetent man who presented with acute bulbar symptoms (difficulty swallowing, change in phonation, and drooling). His symptoms progressed in severity and he ultimately required intubation due to declining lung function and inability to manage his secretions. Clinical examination revealed bulbar dysfunction without involvement of other cranial nerves. A lumbar puncture revealed albuminocytological dissociation: elevated protein (9.8\u00a0g/L), nonerythroid cell count (13 cells/\u00b5L) with predominantly lymphocytic count. He received a five-day course of intravenous immunoglobulin for presumed Guillain-Barr\u00e9 syndrome. Initial magnetic resonance imaging (MRI) showed mild microangiopathic changes in the brain with no parenchymal, leptomeningeal, or cranial nerve enhancement. Cerebrospinal fluid (CSF) analysis was positive for varicella zoster virus (VZV). He was treated with intravenous Acyclovir 10\u00a0mg/kg three times daily for 14 days with no initial improvement and underwent a tracheostomy. Subsequent MRI was consistent with rhombencephalitis. VZV rhombencephalitis with cranial neuropathies represents a rare and potentially fatal condition. Early recognition and investigation with lumbar puncture and imaging are critical for establishing the diagnosis and initiating treatment.\n\nID: 40701363\nTitle: Syringobulbia and Syringomyelia Associated with Intramedullary Ependymoma.\nAbstract: No cases of bulbar palsy secondary to hemorrhage from intramedullary ependymoma into the peritumoral cavity have been reported. A 23-year-old man presented with persistent hiccups, pneumonia, and progressively worsening respiratory dysfunction. Clinical course and imaging findings raised strongly suggested bulbar palsy from a C4-5 intramedullary hemorrhagic lesion. Computed tomography and magnetic resonance imaging of the brain and cervical spine revealed an intramedullary mass at C4-5, accompanied by syringobulbia and syringomyelia, with signals extending from the lower medulla oblongata to the T1 spinal level. The patient underwent laminectomy, myelotomy, and microsurgical mass excision with intraoperative neurophysiological monitoring. Postoperative pathology confirmed the lesion as an ependymoma. Neurologic function improved steadily after surgery. Thus, central respiratory dysfunction should be considered in patients with severe pneumonia without underlying disease. Additionally, contrast-enhanced magnetic resonance imaging is essential for differential diagnosis in bulbar palsy cases.\n\nID: 40628688\nTitle: Worster-Drought syndrome with progressive symptomatic improvement in early infancy.\nAbstract: Worster-Drought syndrome (WDS), or congenital suprabulbar paresis, is characterised by congenital dysarthria, dysphagia and other pseudobulbar paresis without structural abnormalities around the Sylvian fissure on imaging. This rare syndrome is challenging to diagnose, particularly in preterm infants. This report describes a low-birth-weight female infant with WDS who had no sucking reflex from birth, airway obstruction due to saliva retention and muscle rigidity, who was diagnosed with the syndrome at a postconceptional age (PCA) of 1\u2009month. She was discharged with only home oxygen therapy as respiratory support at a PCA of 3 months after gradual improvement in her clinical symptoms. Diagnosis of WDS is difficult in the early postnatal period in preterm cases owing to prematurity but should be suspected when bulbar palsy, including absence of the sucking reflex, persistent dysphagia and obstructed breathing, persists beyond a PCA of 40 weeks and when muscle stiffness is present.\n\nID: 40567532\nTitle: West Nile neuroinvasive disease with poliomyelitis syndrome: A grave phenomenon.\nAbstract: West Nile virus infection poses a significant threat, especially during the warmer months when mosquitoes are abundant. Clinicians must remain vigilant for neuroinvasive illness in patients presenting with febrile symptoms and malaise following mosquito exposure. While magnetic resonance imaging and cerebrospinal fluid analysis aid in differential diagnosis, detecting West Nile immunoglobulin M in serum is crucial for definitive diagnosis. Treatment primarily involves supportive care due to the absence of established regimens, though promising outcomes have been reported with plasma exchange and intravenous immunoglobulin. We present the case of an 83-year-old resident of Alabama, an avid gardener living near a pond, who initially exhibited symptoms of productive cough, diarrhea, fever, and generalized malaise. However, within 48 h, he developed hypoxemia, functional quadriplegia, and bulbar palsy necessitating intubation. Diagnostic evaluations, including magnetic resonance imaging and positive West Nile virus immunoglobulin M in serum, confirmed West Nile virus-associated poliomyelitis viral syndrome, prompting intravenous immunoglobulin therapy. This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions. The case also begs the question of the timing and efficacy of intravenous immunoglobulin and plasma exchange in West Nile virus infection and the fact that more data should be collected on these therapies.\n\nID: 40539137\nTitle: Long-Term Survival in Brown-Vialetto-Van Laere Syndrome: A Case Report Highlighting Respiratory Care.\nAbstract: Brown-Vialetto-Van Laere syndrome (BVVLS) is an extremely rare genetic neurological disorder caused by riboflavin transport deficiency, an autosomal recessive condition mostly\u00a0associated with mutations in the SLC52A2 and SLC52A3 genes. It follows a progressive course, typically characterized by sensorineural deafness, facial weakness, ponto-bulbar palsy, ataxia, and peripheral sensory-motor neuropathy. This disease is\u00a0often associated with childhood mortality if left untreated.\u00a0We report the case of a 68-year-old woman who first noticed a mild hearing loss at the age of 12. This was followed by a slowly progressive onset of bilateral facial paresis, dysarthro-dysphonia, stridor, and tongue atrophy with fasciculations. At 63 years of age, genetic testing revealed a single heterozygous variant in the SLC52A3 gene.\u00a0Although typically autosomal recessive,\u00a0some individuals with classic symptoms and even response\u00a0to riboflavin therapy have been found to carry only a single mutation in either the SLC52A2 or SLC52A3 gene. Therefore, given the\u00a0compatible clinical presentation, a diagnosis of\u00a0BVVLS was considered after discussion with a center of expertise.\u00a0Consequently,\u00a010 mg/kg/day of riboflavin supplementation\u00a0was prescribed for three years, but no significant clinical improvement was observed. Currently, at age 68, the patient is on nocturnal non-invasive mechanical ventilation (NIV)\u00a0and uses assisted airway clearance techniques, including air-stacking maneuvers and mechanical insufflation-exsufflation on demand, due to respiratory compromise secondary to diaphragmatic weakness and vocal cord paralysis. This unique presentation of slowly progressive symptoms and long survival may be related to the single heterozygous SLC52A3 variant found. Respiratory care in BVVLS is currently adapted from other neuromuscular disorders with stronger evidence bases.\u00a0This case highlights the critical role of pulmonology in BVVLS care, including clinical and functional monitoring, early initiation of NIV, and the implementation of airway clearance techniques.\n\nID: 40511217\nTitle: Progressive Bulbar Palsy (PBP) or Bulbar Onset MND: \"A Case Report\".\nAbstract: A patient with enhancing bulbar palsy, a type of efferent neuron disease that causes hypertrophy and twitching of the tongue's musculature, dysphagia, dysarthria, and an excessive buildup of secretions, is described. Enhancing bulbar palsy is a degenerative disorder of the efferent nuclei in the medulla. The patient may consult a dentist at first. Clinicians must possess knowledge regarding the telltale signs and symptoms of this terminal illness to promptly refer patients for neurologic evaluation and initiate appropriate symptomatic treatments.\n\nID: 40488573\nTitle: Care of the person with motor neurone disease: a case study.\nAbstract: People living with conditions such as motor neurone disease (MND) have complex health needs and require input from a multidisciplinary team (MDT) perspective. The nursing associate role has been embedded within the MDT in support of registered professionals since 2016. Case studies giving a personal account of caring for patients with complex health needs can illustrate the challenges faced by those providing such care. This article gives a personal account of caring for a patient with MND and some of the challenges faced. It highlights the importance of understanding complexities of health conditions for nursing associates within current health services, both during training and as a registrant.\n\nID: 40413968\nTitle: Clinical and electrophysiological characteristics and blood markers for short-term prognosis prediction in severe Guillain-Barr\u00e9 syndrome: a retrospective cohort study.\nAbstract: This study aimed to investigate the clinical, electrophysiological characteristics and blood inflammatory markers in severe Guillain-Barr\u00e9 syndrome (GBS) and their correlation with short-term prognosis. Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction. The nomogram model demonstrated an area under the ROC curve of 0.990, reflecting good potential clinical effect. The calibration curve showed good agreement between actual observations and nomogram predictions. The findings indicate that early assessment of the occurrence of bulbar palsy, mEGOS, IMN numbers, and NLR value can predict poor prognosis, with their combination providing improved accuracy for short-term prognosis in patients with severe GBS.\n\nID: 40364643\nTitle: Latest progress and challenges in drug development for degenerative motor neuron diseases.\nAbstract: Motor neuron diseases are sporadic or inherited fatal neurodegenerative conditions. They selectively affect the upper and/or lower motor neurons in the brain and spinal cord and feature a slow onset and a subacute course contingent upon the site of damage. The main types include amyotrophic lateral sclerosis, progressive muscular atrophy, primary lateral sclerosis, and progressive bulbar palsy, the pathological processes of which are largely identical, with the main disparity lying in the location of the lesions. Amyotrophic lateral sclerosis is the representative condition in this group of diseases, while other types are its variants. Hence, this article mainly focuses on the advancements and challenges in drug research for amyotrophic lateral sclerosis but also briefly addresses several other important degenerative motor neuron diseases. Although the precise pathogenesis remains elusive, recent advancements have shed light on various theories, including gene mutation, excitatory amino acid toxicity, autoimmunology, and neurotrophic factors. The US Food and Drug Administration has approved four drugs for use in delaying the progression of amyotrophic lateral sclerosis: riluzole, edaravone, AMX0035, and tofersen, with the latter being the most recent to receive approval. However, following several phase III trials that failed to yield favorable outcomes, AMX0035 has been voluntarily withdrawn from both the US and Canadian markets. This article presents a comprehensive summary of drug trials primarily completed between January 1, 2023, and June 30, 2024, based on data sourced from clinicaltrials.gov. Among these trials, five are currently in phase I, seventeen are in phase II, and eleven are undergoing phase III evaluation. Notably, 24 clinical trials are now investigating potential disease-modifying therapy drugs, accounting for the majority of the drugs included in this review. Some promising drugs being investigated in preclinical studies, such as ATH-1105, are included in our analysis, and another review in frontiers in gene therapy and immunotherapy has demonstrated their therapeutic potential for motor neuron diseases. This article was written to be an overview of research trends and treatment prospects related to motor neuron disease drugs, with the aim of highlighting the latest potentialities for clinical therapy.\n\nID: 40273615\nTitle: Electrodiagnostic characteristics of neuromuscular disease in paediatric intensive care.\nAbstract: Assessing peripheral electrodiagnostic (EDX) tests in paediatric intensive care. Data from patients who had undergone EDX test/s between 2010 and 2019 at a tertiary centre were retrospectively analysed, including final neuromuscular diagnoses, EDX results and demographic information. EDX data included motor and sensory nerve conduction study, needle electromyography (EMG), repetitive nerve stimulation and stimulated single fiber EMG. Final clinical diagnosis was based on several investigations including muscle biopsy, MR imaging, gene testing, EDX-tests and clinical phenotype. 351 patients were identified (56\u00a0% male, average age 42.5\u00a0months), with diagnoses categorised into the following groups: no identifiable neuromuscular disorders (45\u00a0%), neuropathy (13\u00a0%), motor neuron disease (9\u00a0%), isolated bulbar palsy (6\u00a0%), myopathy (14\u00a0%), neuromuscular junction disorders (5\u00a0%), and critical illness neuromyopathy (8\u00a0%). EDX data was stratified into 7 electrodiagnostic categories: normal, neuropathy, motor neuron disease, isolated bulbar palsy, myopathy, neuromuscular junction disorders, and critical illness neuromyopathy. With this stratification we were able to predict the final diagnosis with acceptable accuracy. The prevalence of neuromuscular disease groups in paediatric ICU was defined together with their corresponding EDX characteristics. The study confirms the utility of electrophysiology as a valuable tool for diagnosing and managing neuromuscular conditions in paediatric ICU.\n\nID: 40203549\nTitle: Clinical Characteristics and Prognostic Factors of Anti-GM1 Antibody-Positive Guillain-Barr\u00e9 Syndrome Spectrum Disorders in Children.\nAbstract: The study aimed to analyze the clinical features and risk factors for poor prognosis of Guillain-Barr\u00e9 syndrome (GBS) spectrum disorders in children positive for anti-tetrahexose monosialoganglioside (GM1) antibody. We collected data for children with anti-GM1 antibody-positive GBS spectrum disorders in Affiliated Children's Hospital of Chongqing Medical University between July 2018 and March 2024; 1:1 matching was performed for combined anti-ganglioside or anti-sulfatide antibody. The patients underwent comparative clinical characterization to determine the antibody phenotype-clinical phenotype and to analyze the possible risk factors for the poor prognosis of the disorders. Thirty-seven pediatric patients were recruited. Anti-GM1 antibody-positive GBS spectrum disorders were preceded by a prodromal event (25 of 37, 67.6%). The first symptom was mainly limb weakness (20 of 37, 54.1%), which could be predominately accompanied by autonomic nerve involvement (21 of 37, 56.8%). Seven features showed statistically significant differences (P\u00a0<\u00a00.05) between the positive group and the negative one, including cranial nerve involvement, bulbar palsy, low lower limb muscle strength at discharge, axonal type of electrophysiological typing, and clinical typing of acute motor axonal neuropathy. The GBS disability scores at discharge and at one month after discharge were higher than those in the control group. The shorter time to peak (<7.5\u00a0days) was identified as an independent risk factor for poor short-term prognosis of the disorders. Anti-GM1 antibody-positive GBS spectrum disorders have a relatively specific antibody phenotype-clinical phenotype. The shorter time to peak (<7.5\u00a0days) is an independent risk factor for poor short-term prognosis of the disorders in children.\n\nID: 40084652\nTitle: A Rare Guillain-Barr\u00e9 Syndrome Variant with Multi-Ganglioside Reactivity: A Case of Severe Cranial Nerve Involvement.\nAbstract: We present a rare case of acute immune-mediated polyradiculoneuritis, a Guillain-Barr\u00e9 Syndrome (GBS) variant, manifesting as ophthalmoparesis-ataxia, facial diplegia, and acute bulbar palsy, accompanied by a unique autoimmune profile. A 75-year-old female developed rapidly progressive symptoms, including bilateral non-reactive mydriasis, ptosis, complete ophthalmoplegia, bilateral facial weakness, tongue immobility, palatal paralysis, limb dysmetria, ataxia, and brisk generalized tendon reflexes, all while maintaining a preserved mental state. Symptoms emerged 10 days after a probable gastrointestinal infection. Severe bulbar dysfunction necessitated orotracheal intubation and a tracheotomy. Extensive cranial nerve involvement initially suggested a brainstem lesion, with oculomotor and acute bulbar palsy as prominent signs. However, brainstem and spinal magnetic resonance imaging along with cerebrospinal fluid analysis yielded negative results. Electromyography reveled a sensorimotor demyelinating polyradiculoneuropathy, and serum testing identified IgG antibodies targeting multiple gangliosides, including the disialosyl group and terminal NeuNAc(\u03b12-3)Gal. Treatment with intravenous immunoglobulin (IVIG) led to gradual clinical improvement. This case highlights a rare and severe GBS phenotype characterized by reactivity to multiple gangliosides. It highlights the role of shared ganglioside epitopes in antibody-mediated neurological damage and expands the clinical spectrum of GBS variants. Introducci\u00f3n: Presentamos un caso cl\u00ednico de polirradiculoneuritis aguda inmunomediada que inicialmente se manifest\u00f3 con oftalmoparesia-ataxia, diplegia facial y par\u00e1lisis bulbar aguda, acompa\u00f1ada de un perfil autoinmune caracter\u00edstico. Caso Cl\u00ednico: Describimos el caso de una mujer de 75 a\u00f1os con cl\u00ednica de progresi\u00f3n r\u00e1pida incluyendo midriasis bilateral no reactiva, ptosis, oftalmoplej\u00eda completa, paresia facial bilateral, paresia lingual, par\u00e1lisis del paladar, dismetr\u00eda en todas las extremidades, ataxia y reflejos osteotendinosos aumentados de forma generalizada, con nivel de conciencia preservado. La cl\u00ednica inici\u00f3 despu\u00e9s de una posible infecci\u00f3n gastrointestinal de aparici\u00f3n diez d\u00edas antes. Su estado cl\u00ednico empeor\u00f3 r\u00e1pidamente, requiriendo intubaci\u00f3n orotraqueal y traqueotom\u00eda debido a un compromiso bulbar severo. La afectaci\u00f3n concomitante de m\u00faltiples nervios craneales sugiri\u00f3 una lesi\u00f3n en el tronco encef\u00e1lico, destac\u00e1ndose la par\u00e1lisis oculomotora y bulbar aguda. La resonancia magn\u00e9tica del tronco encef\u00e1lico y m\u00e9dula espinal, junto con las pruebas de l\u00edquido cefalorraqu\u00eddeo, no mostraron alteraciones; la electromiograf\u00eda objetiv\u00f3 una polirradiculoneuropat\u00eda desmielinizante sensitivo-motora. La prueba de anticuerpos antigangli\u00f3sidos mostr\u00f3 positividad contra m\u00faltiples anticuerpos dirigidos al grupo dialosilo y al terminal NeuNAc(\u03b12-3)Gal.

Conclusiones: Nuestro caso ilustra la reactividad a m\u00faltiples gangli\u00f3sidos, destacando los ep\u00edtopos compartidos entre estas mol\u00e9culas y la capacidad de un \u00fanico anticuerpo para dirigirse a diversos tipos de gangli\u00f3sidos, subrayando adem\u00e1s un fenotipo extremadamente raro del s\u00edndrome de Guillain-Barr\u00e9.\n\nID: 40038221\nTitle: HIV associated motor neuron disease (MND): A case series with systematic review of literature.\nAbstract: Human immunodeficiency virus (HIV) associated motor neuron disease (MND) is very rare. HIV infection can cause an MND-like syndrome due to central nervous system (CNS) involvement de novo or during antiretroviral therapy (ART) due to CNS escape. We present two cases: one with a classic amyotrophic lateral sclerosis (ALS) phenotype, which was the manifestation of symptomatic CNS escape from ART, and the second with a primary lateral sclerosis (PLS) phenotype associated with underlying HIV infection. A systematic review of published literature of people living with HIV (PLHIV) who developed ALS/ MND was conducted using the PubMed, Embase, and Lilacs databases. A total of 91 cases were found, 89 of which were obtained from 37 articles, and two were included from our own case series. In patients with HIV-associated MND, 63 patients reviewed had a classic ALS phenotype followed by progressive muscular atrophy variant (12), progressive bulbar palsy (8), PLS (7) and bulbar onset ALS (1). Neuroimaging, electrophysiology, cerebrospinal fluid (CSF) analysis, CSF and serum HIV viral load, and CD4 count investigations were used for diagnosis. Following the initiation or modification of antiretroviral therapy (ART), approximately 70% exhibited an improvement or a stable disease course. HIV-associated MND is a rare condition that can occur in both ART-naive individuals and those on treatment. A proportion of cases (~\u200970%) show improvement with ART. Accurate diagnosis requires the exclusion of opportunistic infections, which remains a critical yet challenging aspect of managing this condition.\n\nID: 39995675\nTitle: Case report: A severe myositis mimicking bulbar palsy after administration of immune checkpoint inhibitors.\nAbstract: Immune Checkpoint Inhibitors (ICI) are nowadays a cornerstone of anti-cancer treatments. However, the wide spectrum of immune-related adverse events (irAEs) represents a challenge in the oncological practice. Our objective is to document rare complications of ICI to help the community of onco-immunologists. We reported the case of a severe myositis mimicking bulbar palsy treated in our Medical Oncology Department together with Internal Medicine Department. We present the clinical work-up (neurological exam, capillaroscopy) and the diagnostic tests (myositis specific and associated antibodies, nerve conduction study, electromyography) leading to this diagnosis. We also discussed the elimination of differential diagnoses (notably with normal MRI and cerebrospinal fluid analysis) and finally the clinical management of this severe irAE. A 57 years woman presented multiple sub-diaphragmatic adenopathies related with an advanced melanoma of unknown primary. She started a treatment with Ipilimumab (Ipi, anti CTLA-4) and Nivolumab (Nivo, anti PD-1) and presented at day 10 a grade IV myositis mimicking bulbar palsy with dysphonia, dysarthria and aphagia. In a multidisciplinary setting, she was treated with IV corticosteroids (methylprednisolone 1 mg/kg started at day 10, with a progressive decrease until 1 mg of prednisone in March 2024), IV immunoglobulins started at day 18 (1.5 g/kg in 2 days, administered monthly, with a progressive decrease and a cessation in June 2022), enteral nutrition, speech therapy and physical therapy, with noticeable improvement. After 4 years of follow-up, and only one infusion of Ipi/Nivo, the melanoma is still in complete response. We report an ICI-induced severe myositis mimicking bulbar palsy after the administration of Ipi/Nivo. The diagnosis and clinical care management of this rare complication requires a multi-disciplinary work-up.\n\nID: 39950622\nTitle: Bickerstaff brainstem encephalitis-Miller-Fisher syndrome (BBE-MFS) overlap with negative anti-GQ1b serology.\nAbstract: Bickerstaff brainstem encephalitis (BBE) and Miller-Fisher syndrome (MFS) are rare post-infectious neurological syndromes, usually involving 'anti-GQ1b ganglioside' antibodies. Both syndromes present with ophthalmoplegia and ataxia. However, BBE is differentiated by altered consciousness or pyramidal signs (central nervous system involvement), while MFS has areflexia (peripheral nervous system involvement). Here, we discuss a case of an elderly woman, who, after an initial episode of upper respiratory tract infection, developed bilateral ophthalmoplegia, facial and bulbar palsy, ataxia, depressed consciousness and areflexia. She was diagnosed clinically as a case of BBE-MFS overlap. However, serology was negative for anti-GQ1b antibodies, and brain imaging and cerebrospinal fluid (CSF) analysis were normal. Despite initial clinical deterioration and the need for intubation, she was treated successfully with intravenous immunoglobulin and eventually recovered. This case demonstrates that BBE and MFS can overlap and that early clinical diagnosis becomes essential even if anti-ganglioside antibodies, CSF and imaging studies are negative.\n\nID: 39922111\nTitle: Audiological findings in Brown Vialetto-Van-Laere Syndrome: A scoping review.\nAbstract: This study aimed to characterize audiological porfile in inviduals with Brown-Vialetto-Van Laere syndrome (BVVLS). This is a scoping review following the methodological structure developed by the Joana Briggs Institute (JBI). The PCC mnemonic was used to elaborate the research question, which resulted in the research question: \"What are the audiological findings in individuals with BVVLS?\". All of the studies included in this review were case reports. The main audiological findings are sensorineural hearing loss and Auditory Neuropathy Spectrum Disorder (ANSD). All individuals presented a severe to profound bilateral hearing loss, related to ANSD.\n\nID: 39880652\nTitle: [A case of L-2-hydroxyglutaric aciduria diagnosed with involuntary movements, in which improvement in motor symptoms was achieved following treatment].\nAbstract: A 49-year-old female presented with the primary complaint of hand tremors. Neurological examination on admission revealed signs of cognitive impairment, bulbar palsy, dystonia, cerebellar ataxia, and pyramidal tract disease. T2-weighted brain MRI revealed hyperintense signals in the subcortical white matter, basal ganglia, and cerebellar dentate nucleus, with no atrophy of the brainstem or corpus callosum. Urinary organic acid analysis revealed elevated 2-hydroxyglutaric acid levels. Although the optical isomers could not be distinguished, L-2-hydroxyglutaric aciduria was diagnosed based on the disease course, symptoms, and characteristic MRI findings. The patient was started on riboflavin-enriched compounds and levocarnitine, resulting in an improvement in the Scale for the Assessment and Rating of Ataxia (SARA) score from 21 to 15 after six months. The case suggests that symptoms in adult patients who have not been treated for a long time can be improved by appropriate diagnosis based on neurological presentation, characteristic MRI findings, and intervention.\n\nID: 42464712\nTitle: Corticospinal Subfiber Neurite Density Index Detects Upper Motor Neuron Degeneration in Prediagnostic Patients With Sporadic Amyotrophic Lateral Sclerosis.\nAbstract: Using multi-shell diffusion MRI, we aimed to identify whether corticospinal tract (CST) subfiber damage can be detected in prediagnostic amyotrophic lateral sclerosis (ALS) patients. We also explored whether the combination of serum neurofilament light chain (NfL) levels and CST subfiber abnormalities may provide better diagnostic performance in differentiating prediagnostic ALS patients from disease controls (DCs) and healthy controls (HCs) than single markers. In this retrospective study, prediagnostic ALS was used as an operational term for patients who presented at baseline with chronic progressive limb weakness or bulbar symptoms, had no clinically evident typical UMN signs, and were subsequently confirmed to have sporadic ALS according to the Awaji criteria during longitudinal follow-up. Patients whose final diagnosis was not ALS after follow-up were classified as disease controls. Probabilistic tractography was performed on baseline MRI data to assess CST subfiber damage in 47 ALS patients, 20 DCs, and 51 HCs. Compared with Controls, ALS patients had significantly lower neurite density index (NDI) values of CST subfibers, particularly those originating from the primary and supplementary motor cortex. The diagnostic performance of the combined model incorporating serum NfL and CST subfiber NDI values in differentiating prediagnostic ALS patients from HCs and DCs was 0.925 and 0.928, respectively, which was better than that of single markers (0.634-0.886 and 0.699-0.856, respectively). Our findings suggest that CST subfibers NDI values are promising neuroimaging markers for detecting in\u00a0vivo UMN degeneration in prediagnostic ALS. Moreover, combining blood and neuroimaging markers may further improve early diagnostic performance.\n\nID: 42444959\nTitle: The role of radiologic assessment in evaluating and monitoring respiratory function in amyotrophic lateral sclerosis (ALS) patients: a narrative review.\nAbstract: Respiratory failure is the primary cause of mortality in amyotrophic lateral sclerosis (ALS), usually caused by progressive neuromuscular respiratory weakness. Standard pulmonary function tests (PFTs) such as maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and both supine and upright forced vital capacity (FVC) are crucial for objective measurements of diaphragmatic weakness but have limitations, including dependence on the patient's performance and the inability to detect early, subclinical diaphragmatic impairment or be used effectively in patients with bulbar symptoms. Radiological assessments, particularly dynamic imaging, have emerged as potential objective tools for evaluating respiratory function. This review comprehensively summarizes findings on the use of diaphragmatic ultrasound (DUS), dynamic chest magnetic resonance imaging (MRI) and deep learning (DL)-based chest computed tomography (CT) for assessing lung function in ALS patients. Key radiological metrics include diaphragm thickness (DT), thickening fraction during inspiration, real-time diaphragmatic excursion, lung diameter changes and changes in pulmonary length and area. These measures have been compared with conventional PFTs in various studies to validate their use for diagnostic accuracy, particularly in early stages of disease. DUS is a non-invasive, widely available tool that strongly correlates with PFT measurements, especially FVC, MIP, and sniff nasal inspiratory pressure (SNIP). Dynamic measures, such as excursion and velocity, appear more sensitive to early dysfunction than thickness alone. Chest dynamic MRI has also shown significant correlations with spirometric parameters. Small cohort studies indicate that dynamic chest MRI is a superior, sensitive tool for detecting early respiratory impairment in asymptomatic patients with normal spirometry. Radiological assessments, primarily DUS, DL-based chest CT and dynamic MRI, offer valuable, objective, and non-invasive methods for monitoring respiratory muscle strength in ALS. These techniques serve as complementary tools to traditional PFTs, particularly in selected clinical scenarios such ALS patients with early disease, bulbar involvement and unable to perform PFTs. Further longitudinal research with larger cohorts is needed to standardize protocols and validate their role as early parameters to guide the timely initiation of supportive interventions like non-invasive ventilation (NIV).\n\nID: 42404894\nTitle: FcRn antagonist and C5 complement inhibitor as early rescue strategies in severe Myasthenia Gravis: a two-case report.\nAbstract: Myasthenia gravis (MG) is an autoimmune neuromuscular disorder in which approximately 10-15% of patients with generalized AChR antibody-positive MG develop refractoriness to standard immunosuppressive therapies. Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy. Further prospective studies are needed to define optimal criteria and timing for early integration of these agents into the therapeutic algorithm.\n\nID: 42375906\nTitle: COVID-19-Triggered Miller Fisher Syndrome Masking Leptomeningeal Progression of Merkel Cell Carcinoma: A Fatal Diagnostic Dilemma.\nAbstract: Miller Fisher syndrome (MFS) is a rare variant of Guillain-Barr\u00e9 syndrome (GBS) classically characterized by the triad of ophthalmoplegia, ataxia, and areflexia. Its association with viral triggers, including SARS-CoV-2, has been increasingly recognized. We present a complex case of a 72-year-old male with metastatic Merkel cell carcinoma undergoing chemotherapy who presented in March 2026 with progressive weakness and near-syncope in the setting of severe anemia and COVID-19 infection. During hospitalization, he developed ophthalmoplegia, areflexia, and ataxia, raising concern for Miller Fisher syndrome. Despite early initiation of intravenous immunoglobulin (IVIG), the patient experienced rapid neurological deterioration with bulbar involvement, leading to respiratory failure requiring mechanical ventilation. This case highlights the diagnostic challenges and clinical complexity of MFS in the setting of malignancy and concurrent infection, emphasizing the importance of early recognition and management of neuromuscular complications in high-risk patients.\n\nID: 42367636\nTitle: Access to care for adults living with spinal muscular atrophy in the UK.\nAbstract: Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder resulting from progressive degeneration and loss of motor neurones in the spinal cord. Current standards of care guidelines focus on a multidisciplinary approach and include recommendations for nine different aspects of care. Although intended for use in all patients with SMA, the guidelines are focused on paediatric best practices and evidence regarding care provision in adults with SMA remains limited. This cross-sectional analysis of a longitudinal registry cohort of adults with SMA study aimed to evaluate the clinical features and corresponding care provision to assess alignment with current care guidelines. Data from 426 patients with genetically confirmed SMA were analysed, including information on respiratory function, bulbar involvement, musculoskeletal complications and daily living support. Results demonstrated a high prevalence of respiratory impairment, bulbar dysfunction, contractures and significant limitations in activities of daily living. However, the care provision observed in this adult cohort did not consistently reflect the recommended standards outlined in the established SMA standards of care recommendations. In particular, gaps were noted in access to respiratory support, physiotherapy and nutritional management. These findings suggest that the application of current standards of care to the adult population is inconsistent. There is a need for improved translation of care provision into adult services to ensure comprehensive and equitable management of SMA across the lifespan.\n\nID: 42360043\nTitle: Comparison of Proteomic Analysis of Cerebrospinal Fluid From Neurological Patients With and Without Amyotrophic Lateral Sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterised by progressive muscle weakness in both bulbar and extremity muscles, leading to a diverse clinical phenotype with motor and non-motor symptoms. Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.\n\nID: 42356052\nTitle: Association Between Clinical Dysphagia Assessment Tools and Videofluoroscopic Findings in Amyotrophic Lateral Sclerosis: A Retrospective Study.\nAbstract: Background and Objectives: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease frequently associated with dysphagia and aspiration risk. This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.\n\nID: 42353943\nTitle: Oral and Swallowing Abilities Tool (OrSAT) in Individuals with Type I SMA Older than 24 Months: A Pilot Study.\nAbstract: Background/Objectives: The advent of disease modifying therapies (DMTs) for Spinal Muscular Atrophy (SMA) has highlighted the need for reliable tools to assess bulbar function in type I individuals. The Oral and Swallowing Abilities Tool (OrSAT) was originally developed to evaluate swallowing and feeding abilities in infants with SMA type I during the first two years of life. This study aimed to assess the applicability of the OrSAT in a cohort of children with SMA type I older than 2 years. Methods: Fifty-two children with genetically confirmed SMA type I, aged 2 to 12.6 years, were included. All participants had received at least one DMT, administered either soon after diagnosis or when treatment became available. Bulbar and feeding abilities were assessed using the OrSAT and results were grouped according to clinical subtype and feeding modality. Given the small sample size of the subgroups and the ordinal nature of OrSAT scores, comparisons between groups were performed using the non-parametric Kruskal-Wallis test. Results: At follow-up, 27 children were orally fed, 19 were exclusively tube-fed, and 6 were tube-fed but were also able to eat some food by mouth. The OrSAT scores reflect a wide spectrum of bulbar function from severe to no impairment. Most children who required exclusive tube-feeding at follow-up had already been tube-fed at treatment initiation, while a small number showed improvement in swallowing abilities and the partial recovery of oral feeding during follow-up. Conclusions: Our results suggest that the OrSAT, previously used only in the first two years of life, may also be applicable in older children to describe bulbar involvement and monitor changes over time. However, further studies are needed to refine the tool for this age group and to formally validate its use in older children with SMA type I. Its use may contribute to the longitudinal assessment of swallowing abilities and support rehabilitative management.\n\nID: 42268433\nTitle: FUS-associated ALS in Taiwan: genetic spectrum, clinical features, and a founder haplotype of p.H517D.\nAbstract: To characterize the genetic spectrum and clinical features of FUS-associated amyotrophic lateral sclerosis (ALS) in a Taiwanese cohort and to investigate whether the recurrent p.H517D variant represents a founder mutation. All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.\n\nID: 42263370\nTitle: Sensory abnormalities and entrapment neuropathies identified by nerve conduction studies in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder primarily affecting motor neurons; however, non-motor symptoms, including sensory and autonomic disturbances, are increasingly recognized. This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.\n\nID: 42254084\nTitle: Myasthenia Gravis With Chronic Kidney Disease: A Diagnostic Challenge.\nAbstract: The coexistence of myasthenia gravis (MG) and chronic kidney disease (CKD) presents a diagnostic challenge due to overlapping clinical features. MG is an autoimmune neuromuscular junction disorder, whereas CKD exhibits the gradual loss of kidney function. We report a 65-year-old male with long-standing CKD who developed progressive neuromuscular symptoms, including bilateral ptosis and bulbar involvement. His anti-acetylcholine receptor antibodies were negative; however, electrophysiological studies demonstrated a significant decremental response (>\u200910%) on repetitive nerve stimulation, supporting the diagnosis of MG. The patient required hemodialysis for worsening renal function and was treated with pyridostigmine for MG symptoms, resulting in clinical improvement. This case emphasizes the importance of distinguishing MG from CKD-related symptoms, particularly in seronegative patients, and highlights the need for careful clinical and electrophysiological evaluation.\n\nID: 42214042\nTitle: Diagnostic Revision From Primary Lateral Sclerosis to Amyotrophic Lateral Sclerosis: A Cohort Study.\nAbstract: Primary lateral sclerosis (PLS) is defined as a pure upper motor neuron syndrome and is a diagnosis of exclusion, amyotrophic lateral sclerosis (ALS) being the most likely alternative diagnostic consideration. A minimum disease duration of 2 years is required for the diagnosis of PLS, after which patients are classified as probable PLS (P-PLS) and subsequently as definite PLS (D-PLS) after 4 years. Our aim is to apply the current diagnostic criteria to a population-based cohort and investigate which clinical characteristics are associated with a diagnostic revision to ALS. This cohort study included patients meeting the current diagnostic criteria for PLS retrospectively from the Dutch Motor Neuron Disease Registry. Diagnostic revision to ALS was based on clinical assessment, EMG findings according to the revised El Escorial Criteria, or if patients had died from disease progression within 4 years of disease onset. Clinical characteristics were compared for patients who underwent diagnostic revision with ALS vs true PLS. Subdistribution hazard ratios (SHRs) for characteristics associated with diagnostic revision were determined using Fine-Gray regression. We included 478 patients (median age of onset 59.3 years, interquartile range 50.8-67.0, 47.9% female), of whom 311 (65.1%) met criteria for P-PLS and 167 (34.9%) for D-PLS at diagnosis. Eighty-eight patients (18%) underwent diagnostic revision to ALS, 76 cases (86%) before 4 years of disease duration. Patients whose diagnosis was revised to ALS had higher median age at onset (63.4 vs 58.0 years, p = 5.20 \u00d7 10-4), more often had bulbar onset (38.6% vs 19.7%, p = 6.19 \u00d7 10-4), and faster progression (median ALS Functional Rating Scale-revised slope 0.43 vs 0.18, p = 6.05 \u00d7 10-11). The risk of diagnostic revision increased if progression rate was faster (SHR 3.08 95% CI 1.69-5.60, p = 2.35 \u00d7 10-4) and if diagnosis was P-PLS compared with D-PLS (SHR 3.08, 95% CI 1.65-5.74, p = 3.96 \u00d7 10-4). In our cohort, most diagnostic revisions from PLS to ALS were in patients with a disease duration of less than 4 years. Besides disease duration, a faster progression rate was associated with diagnostic revision from PLS to ALS. Adding progression rate to the current diagnostic criteria could increase accuracy and help identify patients at higher risk of developing ALS.\n\nID: 42191932\nTitle: Motor neuron disease in Africa: a critical appraisal of the literature.\nAbstract: Motor neuron disease (MND) refers to a group of neurodegenerative diseases that cause motor neuron degeneration and death. The most common subtype, amyotrophic lateral sclerosis (ALS), is characterized by both upper and lower motor neuron impairment, which can manifest clinically in the bulbar region or asymmetrically in a limb. Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care. We share our perspective on how the ALS Africa Network is coordinating a shift in the African MND landscape to improve patient care.\n\nID: 42185781\nTitle: Association between creatinine-to-cystatin C ratio and ALSFRS-R across clinical phenotypes.\nAbstract: Reliable and accessible biomarkers for amyotrophic lateral sclerosis (ALS) are scarce. Creatinine (Cre) reflects muscle mass, whereas cystatin C (CysC) may reflect neurodegeneration without being directly influenced by muscle mass; however, both have limitations. We aimed to investigate whether the creatinine-to-cystatin C ratio (Cre/CysC) was cross-sectionally associated with functional status in patients with ALS. We retrospectively analyzed 30 patients diagnosed with ALS at the National Organization Hospital Okinawa Hospital between 2021 and 2024. Baseline ALS Functional Rating Scale-Revised (ALSFRS-R) scores and serum Cre and CysC levels were recorded. Associations with the ALSFRS-R were assessed using Spearman's correlation, with subgroup analyses by sex, site of onset, age at diagnosis, body mass index (BMI), and diagnostic delay. Multivariable analyses were performed to examine the independent association between Cre/CysC and ALSFRS-R while accounting for relevant clinical covariates. Cre/CysC showed a stronger cross-sectional correlation with ALSFRS-R (rs=0.648, p\u2009=\u20090.0001) than Cre alone (rs =0.427) or CysC (rs =-0.119). Exploratory subgroup analyses showed generally positive associations in several subgroups, although no statistically significant association was observed in the small bulbar-onset subgroup. In multivariable analysis adjusted for age at onset and diagnostic delay, Cre/CysC remained independently associated with ALSFRS-R (\u03b2\u2009=\u200920.1, 95% CI 6.41-33.9, p\u2009=\u20090.006). Given the small sample size and cross-sectional design, these findings should be interpreted as exploratory. Cre/CysC showed a stronger cross-sectional association with functional status than either marker alone. Because it is derived from routine laboratory tests, Cre/CysC may represent a simple exploratory measure associated with functional status in ALS. However, the present findings do not establish prognostic utility or fully account for disease stage and biological heterogeneity. Prospective longitudinal studies incorporating disease progression measures and broader clinical and genetic characterization are warranted.\n\nID: 42174849\nTitle: A Consensus Clustering Approach to Amyotrophic Lateral Sclerosis Phenotyping.\nAbstract: Amyotrophic Lateral Sclerosis (ALS) phenotyping is a challenging task due to its heterogeneous nature and low prevalence. In this paper, we introduce a data-driven approach to support the characterization of ALS phenotypes based on clinical data from a battery of examinations. A consensus clustering method is proposed to identify stable clusters across multiple random data sub-samples, with the objective of discovering whether the retrieved patients' groups and related features align with clinical phenotypes and medical knowledge. Results suggest consistent profiles for bulbar onset ALS patients, driven by onset characteristics, whereas spinal onset ALS patients exhibit greater within-phenotype heterogeneity.\n\nID: 42168009\nTitle: Primary Lateral Sclerosis French National Diagnostic and Care Protocol.\nAbstract: Primary lateral sclerosis (PLS) is a rare neurodegenerative motor neuron disease characterized by progressive and selective involvement of the central motor neuron within the bulbar and spinal regions. It is estimated to account for 1-5% of motor neuron diseases and typically presents in the fifth or sixth decade of life, with a slight male predominance. According to current consensus criteria, the diagnosis relies on the demonstration of progressive upper motor neuron dysfunction in the absence of lower motor neuron involvement, with persistence of isolated upper motor neuron signs for at least four years in order to exclude a slowly progressive upper motor neuron-predominant form of amyotrophic lateral sclerosis (ALS). The French Motor Neuron Disease Network (FILSLAN) developed a National Diagnostic and Care Protocol (PNDS) with the aim of standardizing diagnostic criteria, optimizing differential diagnosis, and providing evidence-based recommendations for therapeutic management and follow-up across the national territory. These recommendations were elaborated in accordance with the methodological framework of the French National Authority for Health for rare diseases. The protocol provides practical guidance for establishing PLS as a diagnosis of exclusion, distinguishing it from ALS and hereditary spastic paraplegias, and organizing appropriate clinical and paraclinical investigations. It also outlines indications for genetic testing in selected cases and defines a multidisciplinary management strategy centered on symptomatic treatment, early rehabilitation, respiratory and nutritional surveillance, and psychosocial support. Given the slower progression of PLS compared with ALS, biannual multidisciplinary follow-up is generally appropriate. This protocol aims to harmonize clinical practice and improve patient care while acknowledging the current absence of disease-modifying therapies.\n\nID: 42166520\nTitle: Clinical characterization and natural history of ALS8/VAPB p.Pro56Ser: upper motor neurone signs, survival, and functional milestones in 78 patients.\nAbstract: Amyotrophic lateral sclerosis type 8 (ALS8), caused by the VAPB p.Pro56Ser mutation, is a rare familial motor neurone disease with an incompletely characterized profile. We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9\u2009years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9\u2009years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0\u2009years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p\u2009=\u20090.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.\n\nID: 42141072\nTitle: Axonal dying back of upper motor neurons in human ALS.\nAbstract: Patients with amyotrophic lateral sclerosis (ALS) typically present with arm, leg, or bulbar weakness. While genetics plays a clear role, it cannot explain why symptoms start focally or how upper (UMN) and lower motor neuron (LMN) systems are linked. In this clinicopathological case series, we examined the relationships between UMN/LMN disease in ten ALS patients. Detailed clinical assessments and motor cortex, brainstem, and spinal cord tissues were collected via rapid autopsy. Tissues were stained for UMN/LMN, myelin, axons, microglia, and pTDP43, and RNA-sequencing was performed. None of the patients had symptoms of frontotemporal dementia (FTD), but all had focal sites of clinical onset and both UMN/LMN involvement. LMN degeneration and microglial activation were highest at disease onset sites. UMN degeneration was present at all spinal cord levels through the medulla, regardless of onset site. Surprisingly, there was no evidence of UMN axonal degeneration above the brainstem. While extensive pTDP43 aggregates were seen in degenerating LMNs, no pTDP43 aggregates were seen in UMN cell bodies or their axons. RNA-sequencing implicated inflammatory pathways at sites of disease onset. Our findings suggest that some ALS patients without FTD have a dying back of UMN axons rather than a primary upper neuronopathy of neurons.\n\nID: 42091851\nTitle: Predictive Factors for Non-response to First Use of Polyvalent Intravenous Immunoglobulin in Generalised Myasthenia Gravis.\nAbstract: Myasthenia gravis (MG) is an autoimmune neurological disorder affecting the neuromuscular junction. Rapid clinical deterioration during a myasthenic crisis (MC) or severe exacerbation may be life-threatening due to respiratory or bulbar involvement. Plasma exchange (PLEX) and intravenous immunoglobulin (IVIg) are two rescue therapies that show comparable efficacy in this setting. However, the characteristics of patients who respond poorly to IVIg remain insufficiently described. The aim of this study was to identify predictive factors of non-response to IVIg administered during a first MC or exacerbation. This was a single-centre retrospective cohort study carried out at a French referral centre for neuromuscular diseases between 2017 and 2023. Adult patients with generalised MG experiencing a first MC or exacerbation and treated for the first time with IVIg were included in the study. Data on clinical, laboratory, electrophysiological and therapeutic variables were collected. Treatment response was defined as the maximum gain in Garches clinical score following IVIg, adjusted for baseline score. A total of 93 were included in the study. The median age of the cohort was 68 (interquartile range [IQR] 49-76) years, and the median delay from diagnosis was 0.7\u00a0years. The median baseline Garches score was 66/100 (IQR 55-75) points, which improved to 85/100 (IQR 75-94) points after treatment. Bulbar involvement was significantly associated with a greater response to IVIg. In this large and heterogeneous cohort, IVIg demonstrated consistent efficacy without identification of significant predictors of non-response. These findings support IVIg as a reliable and evidence-based first-line therapy for patients with MG experiencing exacerbation or MC.\n\nID: 42040341\nTitle: Translation of surface electromyography into a clinically applicable objective bulbar assessment tool to improve measurement-based care in amyotrophic laterals sclerosis.\nAbstract: This study aims to translate surface electromyography (sEMG) into a clinically applicable, objective tool for assessing bulbar involvement in amyotrophic lateral sclerosis (ALS). A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS.\n\nID: 42015728\nTitle: A nomogram for estimating baseline respiratory insufficiency in patients with amyotrophic lateral sclerosis.\nAbstract: To develop and validate a nomogram for estimating the risk of baseline respiratory insufficiency in patients with amyotrophic lateral sclerosis (ALS). This also aims to analyze the association between readily available clinical predictors and pulmonary function. This retrospective study assessed 142 ALS patients treated at the First Hospital of Shanxi Medical University from August 2020 to June 2023. ALS was diagnosed based on revised El Escorial criteria with Awaji modifications. Clinical data and pulmonary function tests (PFTs) were performed during a single hospital stay. Respiratory insufficiency was marked as forced vital capacity (FVC) < 80% of predicted. Muscle strength of neck and limbs was measured with the Medical Research Council (MRC) scale. Multivariable logistic regression evaluated independent predictors of respiratory insufficiency. A nomogram was created and internally validated using bootstrap resampling (1,000 iterations). Model performance was assessed with ROC curve analysis, calibration curve analysis, and decision curve analysis (DCA). Of the 142 patients, 30 (21.1%) presented with baseline respiratory insufficiency. In the multivariable analysis, neck flexor muscle strength (OR = 0.497, 95% CI: 0.321-0.769; p\u2009=\u20090.002) and bulbar onset (OR = 4.392, 95% CI: 1.674-11.521; p\u2009=\u20090.003) were independent predictors in the multivariable analysis. The nomogram showed good discrimination and calibration (AUC = 0.823, 95% CI: 0.739-0.907). Weakness of neck flexors and bulbar onset are independently associated with baseline respiratory insufficiency in ALS patients. The proposed nomogram may serve as a useful tool for baseline screening and risk stratification. External validation in larger multicenter cohorts is warranted before clinical application.\n\nID: 42013513\nTitle: Association between statin use and survival in patients with ALS: A propensity score-matched analysis.\nAbstract: To evaluate the association between statin use, disease progression, and survival in patients with amyotrophic lateral sclerosis (ALS) using data from the Pooled Resource Open-Access ALS Clinical Trials (PRO-ACT) database. We conducted a retrospective cohort study of adults (\u226518\u00a0years) diagnosed with ALS and included in the PRO-ACT database. Statin exposure was defined as any statin use at cohort entry. Statin users were matched 1:1 to non-users using propensity score matching based on age, baseline ALS Functional Rating Scale (ALSFRS), disease duration, ethnicity, bulbar onset, riluzole use, and cardiovascular or metabolic comorbidities. Participants were followed from cohort entry or statin initiation until death, end of follow-up (36\u00a0months), or loss to follow-up. The primary outcome was all-cause mortality at three years. The secondary outcome was disease progression, defined as time to a four-point decline in ALSFRS score. Cox proportional hazards models were used to estimate hazard ratios (HRs). Among 3439 eligible participants, 131 statin users (mean age 63.1\u00a0years; 34% female) were identified and matched to 131 non-users. Statin use was not associated with all-cause mortality at three years (HR 0.97; 95% CI 0.66-1.44; P\u00a0=\u00a00.89). Disease progression was also similar between statin users and non-users (HR 1.02; 95% CI 0.80-1.31; P\u00a0=\u00a00.90). In this large observational cohort, statin use was not associated with survival or disease progression in ALS. These findings do not support statin initiation or discontinuation based solely on ALS diagnosis or disease course.\n\nID: 42011445\nTitle: Bulbar Onset Generalized Myasthenia Gravis in an Elderly Patient: A Diagnostic Challenge.\nAbstract: Myasthenia gravis (MG) can present with variable and atypical symptoms, particularly in older adults, where isolated bulbar involvement may mimic stroke or motor neuron disease. We report a case of an elderly patient with late-onset, acetylcholine receptor (AChR) antibody-positive generalized myasthenia gravis who initially presented with ptosis, followed by progressive dysphagia and dysarthria, and subsequently developed head drop. Electromyography (EMG) confirmed a neuromuscular junction disorder, and serology demonstrated markedly elevated AChR antibodies. Early initiation of pyridostigmine and corticosteroids led to rapid clinical improvement, with the Myasthenia Gravis Activities of Daily Living (MG-ADL) score decreasing from 11/24 to 0/24 within three weeks. This case highlights the importance of considering MG in elderly patients presenting with isolated bulbar symptoms and demonstrates the diagnostic value of electrophysiology and antibody testing for timely treatment.\n\nID: 41987036\nTitle: Genetic epidemiology of C9orf72 repeat expansion associated amyotrophic lateral sclerosis in Hungary.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive motor neuron loss. The most common genetic cause of ALS is the hexanucleotide repeat expansion in the C9orf72 gene, which is associated with earlier disease onset, faster progression, and an increased frequency of cognitive and psychiatric involvement. Data on population-specific characteristics of C9orf72-associated ALS remains limited in Central and Eastern Europe. Between 2011 and 2024, a total of 959 ALS patients fulfilling established diagnostic criteria were screened for C9orf72 repeat expansions at two Hungarian centers. Hexanucleotide repeat expansions were analyzed using repeat-primed long-read PCR. Repeat numbers exceeding 30 were considered pathogenic. Clinical, demographic, and disease course data were retrospectively collected and analyzed. Pathogenic C9orf72 repeat expansions were identified in 63 of 959 patients, corresponding to a prevalence of 6.57% among Hungarian ALS patients. Bulbar onset was the most common presentation and was associated with faster progression and shorter survival (mean survival: 27.8\u00a0months). Cognitive impairment and psychiatric comorbidities were present in a substantial proportion of patients and were associated with slower functional decline. Regional differences in survival were observed, likely reflecting disparities in healthcare access rather than biological factors. This study provides the first comprehensive national characterization of C9orf72 repeat expansion-associated ALS in Hungary, based on a genetically defined cohort assembled over 13\u00a0years. Despite limitations related to retrospective data collection and cohort size, this ethnically homogeneous dataset offers valuable insight into population-specific clinical and epidemiological features and complements larger international studies. Systematic characterization and longitudinal follow-up of genetically defined, trial-ready ALS cohorts will be essential as targeted therapies for C9orf72-associated ALS approach clinical implementation.\n\nID: 41981045\nTitle: Speech-based digital endpoints track ALS progression and align with standard clinical outcomes: evidence from the VRG50635 trial.\nAbstract: We report on the utility of speech-based digital endpoints measured during a Phase 1b study of VRG50635 in Amyotrophic Lateral Sclerosis (ALS). Fifty-four participants with ALS were enrolled and participated in an 8-week pretreatment run-in, followed by three 8-week dosing periods and an 8-week follow-up. They completed a speech assessment every two weeks in the clinic or at home. We observed moderate to high correlations between digital measures of speech timing and articulatory motor function, and the ALS Functional Rating Scale-Revised, slow vital capacity and plasma neurofilament light chain. Furthermore, speech measures can show functional decline before the ALSFRS-R does, while also capturing differences between participants with bulbar symptoms and those without. The results support the feasibility and utility of digital speech endpoints to study disease impact in ALS clinical trials.\n\nID: 41947659\nTitle: The Repercussions of Amyotrophic Lateral Sclerosis on the Orofacial Sphere: A One-Year Prospective Longitudinal Study.\nAbstract: The aim of this longitudinal study was to evaluate the repercussions of amyotrophic lateral sclerosis (ALS) on orofacial function, dental health, and the development of malocclusions, in order to assess whether disease progression influences oral and craniofacial outcomes. Thirteen patients diagnosed with ALS according to the Gold Coast criteria were enrolled to be examined at two time points (T1 and T2), with a one-year interval. The ALS Functional Rating Scale-Revised (ALS-FRS-R), the Nordic Orofacial Test Screening (NOT-S), the Decayed Missing and Filled Teeth (DMFT) index, Plaque Index, and standard orthodontic assessments were used to quantify changes in disease progression, orofacial function, dental health, and occlusal parameters, respectively. Statistical evaluation: Paired sample t-tests were performed to evaluate differences between T1 and T2 for continuous variables. Chi-square and Fisher's exact tests were used for categorical data. Multiple linear regression analyses were carried out to assess potential associations between general disease progression, ALS type, and orofacial functional or dental health decline. A significance level of p < 0.05 was adopted for all analyses. Thirteen patients were examined at T1, 10 of whom completed both evaluations. A significant deterioration in the general disease condition was observed (ALS-FRS-R: mean difference -6.0 \u00b1 6.98; p = 0.024). Orofacial function worsened significantly as reflected by an increase in NOT-S total score (+2.3; p = 0.001). Dental health also declined, with a significant increase in DMFT (+1.8; p = 0.014) and Plaque Index (+0.4; p = 0.004). However, occlusal parameters remained stable over the 12-month period, with no significant changes in overjet (p = 0.860) or overbite (p = 0.347). The bulbar type of ALS seems to show worse deterioration of orofacial function over time, and individuals with more significant general disease progression also showed worse orofacial functional decline. ALS has a significant impact on orofacial function and dental health, characterized by neuromuscular deterioration, increased plaque accumulation, and a higher number of affected teeth. Despite this decline, dental occlusion appears to remain stable in the short term. These findings highlight the need for interdisciplinary and preventive oral care strategies in the management of patients with ALS, aiming to preserve oral function and quality of life in a progressively disabling disease.\n\nID: 41944166\nTitle: Transforming the natural course of infantile onset thymidine kinase 2 deficiency through early nucleoside replacement therapy.\nAbstract: Thymidine kinase 2 (TK2) deficiency is an ultra-rare, severe mitochondrial myopathy caused by pathogenic variants in TK2 and characterized by a wide range of ages at onset. The infantile form, presenting before 2 years of age, is the most rapidly progressive and is associated with a high risk of early mortality. We describe the clinical outcomes of early nucleoside therapy in a series of children with infantile-onset TK2 deficiency. We retrospectively reviewed four children with genetically confirmed infantile-onset TK2 deficiency treated with oral deoxycytidine/deoxythymidine (dC/dT) through an Early Access Program at two centers. Dosing was escalated to 800\u2005mg/kg/day as tolerated. Patients were followed at baseline, Month 1, and regular intervals thereafter. Outcomes included neurological examinations, eight motor milestones, and respiratory and feeding support. Safety laboratory results, neuroimaging, and biopsy findings were reviewed. Treatment began at 19-24 months (median duration 26 months; range: 4-81). All presented within the first year with hypotonia, motor regression, and respiratory and/or bulbar involvement. Two required invasive ventilation and three required tube feeding before therapy. After dC/dT initiation, all improved with no further milestone loss. Three achieved independent ambulation and stair climbing; the fourth, at 4 months of therapy, has begun unassisted walking. Both tracheostomized patients were weaned from ventilation, and enteral feeding was discontinued in all three within 1-6 months. Only mild dose-related diarrhea occurred in one patient. Early nucleoside therapy halts disease progression and restores motor function in infantile-onset TK2 deficiency, the most severe form of the disease.\n\nID: 41904038\nTitle: Clinical characteristics and peripheral immune profile analysis of thymoma-associated myasthenia gravis with anti-titin antibodies: a multicenter, retrospective study.\nAbstract: Thymoma-associated myasthenia gravis (TAMG) patients with anti-titin antibodies exhibit uncertain clinical and immunological relevance. We analyzed 91 TAMG patients (40 Titin\u00a0+\u00a0group, 51 Titin- group) treated between 2019 and 2025. Clinical features, severity scores, and peripheral immune markers were compared, and finally tested the correlation between the latter and severity. Titin\u00a0+\u00a0group had higher rates of MGFA\u00a0\u2265\u00a0III (55.0% vs. 25.5%, p\u00a0=\u00a00.004) and elevated QMG bulbar scores [3.00 (0.75-3.00) vs. 0.00 (0.00-0.00), p\u00a0=\u00a00.002]. They also showed increased platelets (249.4\u00a0\u00b1\u00a062.0 vs. 224.2\u00a0\u00b1\u00a048.0\u00a0\u00d7\u00a0109/L, p\u00a0=\u00a00.033), monocytes (0.59\u00a0\u00b1\u00a00.27 vs. 0.46\u00a0\u00b1\u00a00.23\u00a0\u00d7\u00a0109/L, p\u00a0=\u00a00.018), and IL-1\u03b2 [4.20 (1.85-12.06) vs. 1.13 (0.46-3.13) pg/mL, p\u00a0=\u00a00.009]. IL-6 correlated with MGFA class (r\u00a0=\u00a00.67, p\u00a0=\u00a00.004) and QMG respiratory scores (r\u00a0=\u00a00.70, p\u00a0=\u00a00.026); NLR with QMG (r\u00a0=\u00a00.60, p\u00a0=\u00a00.018) and MG-ADL (r\u00a0=\u00a00.53, p\u00a0=\u00a00.044); TNF-\u03b1 (r\u00a0=\u00a00.86, p\u00a0=\u00a00.014) and IL-8 (r\u00a0=\u00a00.79, p\u00a0=\u00a00.036) with MG-QoL15; PLR with QMG gross motor (r\u00a0=\u00a00.53, p\u00a0=\u00a00.041) and bulbar scores (r\u00a0=\u00a00.58, p\u00a0=\u00a00.025); SII and IL-2 with QMG bulbar (r\u00a0=\u00a00.53, p\u00a0=\u00a00.046) and respiratory scores (r\u00a0=\u00a00.78, p\u00a0=\u00a00.040), respectively. Anti-titin antibodies positive TAMG is associated with more severe disease-especially bulbar involvement. NLR, PLR, IL-2, IL-6, IL-8, and TNF-\u03b1 are candidate biomarkers of severity.\n\nID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.\n\nID: 41872984\nTitle: Muscle MRI and Muscle Ultrasound Applications in MND/ALS: Academic Insights and Clinical Opportunities.\nAbstract: There is an unmet need for the clinically relevant ALS biomarkers to facilitate an accurate diagnosis in suspected cases, monitor disease progression and evaluate response to therapy in clinical trials. While the MND/ALS literature is dominated by innovative brain studies, motor disability in ALS is primarily driven by neurogenic muscle change impacting mobility, dexterity, respiratory and bulbar function. With the intention of raising awareness of muscle-derived imaging markers in ALS, a systematic review has been conducted. Study designs, imaging methods, data interpretation frameworks, and cohort characteristics were systematically evaluated to identify innovative approaches and barriers to clinical implementation. A total of 219 studies were screened and 73 original studies selected for systematic review; 37 muscle MRI studies and 36 studies using ultrasound, PET or CT. All of the selected studies successfully captured ALS-associated muscle degeneration and their methods included the evaluation of muscle dimensions (thickness/volumes n\u2009=\u200934), 'acute' denervation (water content, n\u2009=\u200915), fasciculation counts (n\u2009=\u200914), 'chronic' neurogenic change (fat content, n\u2009=\u200921), metabolic changes (n\u2009=\u20094), diffusion alterations (n\u2009=\u20098) and echo intensity changes (n\u2009=\u200913). Despite the huge impact of lower motor neuron dysfunction on the patients' independence, survival and quality of life, muscle imaging is a glaringly overlooked frontier of MND/ALS research. This is a missed opportunity, as a variety of non-invasive quantitative muscle imaging techniques have been successfully used in other neurological conditions; these protocols are easy to implement on commercial MRI and ultrasound platforms and recent studies have demonstrated their ease of use and potential clinical utility.\n\nID: 41871620\nTitle: Clinical and Sociodemographic Profile of Familial Amyotrophic Lateral Sclerosis Type 8 Compared to the Sporadic Form.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a rare degenerative disease of motor neurons, predominantly sporadic, with approximately 10% of the cases showing familial inheritance.To characterize the clinical and sociodemographic profile of patients with familial ALS type 8 (fALS8) and compare it with sporadic ALS (sALS).We reviewed the medical records (1997-2022) from a specialized Brazilian center. Patients with a confirmed diagnosis of ALSs were included, and sociodemographic and clinical data were collected.The sample was composed of 89 ALS patients, with a slight female predominance (53%) and a high frequency of fALS8 cases (45%). The fALS8 patients were diagnosed at a younger age, at approximately 50 years, compared to 53 years among the sALS patients (p\u2009=\u20090.043). Lower limb onset predominated in the fALS8 group (87%), while the sALS group showed more heterogeneous presentations, including bulbar onset (14%). The time until the diagnosis was significantly longer in the fALS8 group compared to the sALS group, both from symptom onset (approximately 51 versus 30 months respectively; p\u2009<\u20090.001) and after admission to a specialized center (7 versus 4 months respectively; p\u2009=\u20090.002). Dysphagia and gastrostomy were more frequent in the sALS group compared to the fALS8 group (p\u2009=\u20090.02 and p\u2009<\u20090.01 respectively), and older age at diagnosis was associated with worse functional scores.The fALS8 group presented with distinct clinical and demographic features compared to the sALS group, including younger age at diagnosis, more homogeneous symptom onset, and lower frequency of dysphagia and need for gastrostomy. The diagnosis was more delayed in the fALS8 group, and older age at diagnosis was associated with worse functional status. The current study contributes to the scarce data on fALS8 in South America.\n\nID: 41837970\nTitle: Safety and Efficacy of PrimeC in Amyotrophic Lateral Sclerosis: The PARADIGM Randomized Clinical Trial.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease with limited treatment options. PrimeC is a fixed-dose oral combination of celecoxib and ciprofloxacin designed to target ALS-related mechanisms, including neuroinflammation, iron homeostasis, and dysregulated microRNAs. To evaluate the safety, tolerability, and potential efficacy of PrimeC in people living with ALS. This was a randomized, double-blind, placebo-controlled, phase 2b trial conducted at 4 ALS referral centers from May 2022 to November 2023 and followed by 12-month open-label extension. Adults with definite or probable ALS and disease duration of 30 months or less were eligible. Of 73 screened, 69 were randomized and 68 were included in the intent-to-treat population. Participants were randomized 2:1 to receive PrimeC or placebo for 6 months, followed by open-label extension PrimeC for all. The primary outcome was safety and tolerability. The prespecified primary biomarker outcome was plasma neuron-derived-exosomal TAR DNA-binding protein 43 (TDP-43) or prostaglandinJ2. Secondary outcomes included change in ALS Functional Rating Scale-Revised (ALSFRS-R) score at 6 and 18 months, survival, and time-to-composite events. Exploratory biomarkers included neurofilament light chains, iron-regulatory proteins, and circulating microRNAs. The 68 participants were well balanced in age at entry and sex. In the PrimeC group, the mean (SD) age was 59.1 (9.1) years, and 27 of 45 participants were male. In the placebo group, the mean (SD) age was 55.0 (13.0) years, and 14 of 23 participants were male. PrimeC was well tolerated, with a safety profile comparable to placebo (adverse event rate, 66.7% PrimeC vs 65.2% placebo). Drug-related adverse events were more frequent with PrimeC (20.0% vs 4.3%), mostly mild to moderate, and transient. At month 6, the mean ALSFRS-R difference was 2.23 points between PrimeC and placebo (95% CI, -0.61 to 5.07; P\u2009=\u2009.12). At month 18, ALSFRS-R scores in participants continuously treated with PrimeC maintained a difference (7.92 points; 95% CI, 2.25 to 13.60; P\u2009=\u2009.007), with significant bulbar difference (3.18 points; 95% CI, 1.32 to 5.04; P\u2009=\u2009.001). Continuous treatment was associated with lower risk of ALS complications, including hospitalization, respiratory failure, or death (HR, 0.36; 95% CI, 0.15-0.85; P\u2009=\u2009.02). In the double-blind period, transferrin levels were preserved with PrimeC (1.90 \u03bcmol/L difference; P\u2009=\u2009.03), the negative ferritin-ALSFRS-R correlation observed in placebo (\u03c1\u2009=\u2009-0.50; P\u2009=\u2009.02) was abolished, and ALS-associated microRNAs were downregulated (log2 fold change: miR-199a-3p, -1.87; false discovery rate [FDR] P\u2009=\u2009.004; miR-199a-5p, -2.23; FDR P\u2009<\u2009.001; miR-181a-5p: -1.89; FDR P\u2009=\u2009.001; miR-181b-5p, -1.62; FDR P\u2009=\u2009.005). Prespecified neuron-derived exosome TDP-43/PgJ2 analyses will be reported separately following completion of development and analyses. PrimeC was safe and well tolerated over 18 months. Although not powered for efficacy, functional and biomarker findings support a confirmatory trial. ClinicalTrials.gov Identifier: NCT05357950.\n\nID: 41829459\nTitle: Quantification of Tongue Motor Dysfunction in Amyotrophic Lateral Sclerosis Using a Smartphone-Based Task and Deep Learning.\nAbstract: Bulbar dysfunction is a major complication of amyotrophic lateral sclerosis (ALS). This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.\n\nID: 41826605\nTitle: Post-COVID-19 surge in Guillain-Barr\u00e9 syndrome during the Omicron wave in China with clinical characteristics and potential immune-mediated pathways.\nAbstract: This multicenter study investigated the epidemiological and clinical characteristics of Guillain-Barr\u00e9 syndrome (GBS) during China's Omicron wave (December 2022-February 2023), and compared the number of GBS hospitalizations with the historical data for the same period from 2018 to 2022. A retrospective analysis was conducted at two tertiary hospitals, categorizing patients into COVID-GBS (case group) and Non-COVID-GBS (control group). During the Omicron wave, the number of GBS hospitalizations was 1.5 times higher compared to the period of 2018-2019 (99 cases vs. 66 cases). Poisson regression analysis confirmed a significant increase in GBS incidence during the Omicron wave (December 2022-February 2023) compared to the 2018-2019 baseline period, with an IRR of 1.541 (95% CI: 1.123-2.129, p\u2009=\u20090.0079). COVID-19-associated GBS patients were significantly older (54.04 vs. 42.06 years, p\u2009=\u20090.002) and exhibited higher rates of cranial nerve involvement (p\u2009=\u20090.014), particularly bulbar involvement (p\u2009=\u20090.009). Acute severity was greater in COVID-19-associated cases, evidenced by elevated ICU admissions, higher peak GBS disability scores (p\u2009=\u20090.048), increased mechanical ventilation needs, and one fatality. The median latency from COVID-19 infection to neurological onset was 9.5 days (IQR: 8-14). Despite these acute differences, 6-month disability outcomes showed no significant divergence between groups, suggesting similar long-term prognoses. The surge in GBS incidence aligns with broader reports of elevated GBS rates during COVID-19 surges, though mechanistic links may involve immune-mediated pathways rather than direct viral causation.\n\nID: 41822190\nTitle: Familial SCA14: A case report with review.\nAbstract: Spinocerebellar ataxia type 14 (SCA14) is a rare autosomal dominant neurodegenerative disorder caused by mutations in the PRKCG gene, which encodes protein kinase C\u03b3 (PKC\u03b3). The clinical manifestations are heterogeneous, ranging from slowly progressive pure cerebellar ataxia to complex phenotypes with sensory or extrapyramidal involvement. To the best of our knowledge, the present report is the first to describe a Han Chinese family carrying the PRKCG c.424T>G (p.C142G) mutation, which has previously only been described in Danish and Japanese cohorts. The proband, a 72-year-old man, developed gait instability in his 40s, progressing to dysarthria, intention tremor, oculomotor slowing and sensory impairment. Brain MRI revealed severe diffuse cerebellar atrophy. The siblings and daughter of the patient presented with variable ataxic symptoms, confirming autosomal dominant inheritance. Genetic testing by next-generation sequencing identified the heterozygous c.424T>G mutation, co-segregating in affected family members. This mutation localizes to the C1 regulatory domain of PKC\u03b3, a zinc-finger structure critical for diacylglycerol binding and kinase autoinhibition. Substitution of cysteine by glycine at codon 142 destabilizes zinc coordination, impairs protein stability and disrupts membrane recruitment. Functional evidence suggests that C142G induces aberrant kinase activity, misfolding and altered MAPK signaling, resulting in chronic cellular stress without rapid neuronal death, thus accounting for the indolent course of the disease compared with that of polyglutamine SCAs. The present findings expand the knowledge regarding the ethnic and geographic distribution of the codon 142 mutation and highlight the complexity of genotype-phenotype associations, as clinical presentations varied from mild gait ataxia to cognitive impairment and bulbar involvement. The report underscores the value of early genetic testing in unexplained ataxia, facilitating accurate diagnosis, genetic counseling and individualized management. Further functional studies are warranted to clarify the pathogenic mechanisms and to explore potential targeted therapies for SCA14.\n\nID: 41819726\nTitle: Respiratory alterations in patients with amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a progressive and heterogeneous neurodegenerative disease that manifests itself in different phenotypes depending on the anatomical region affected. Retrospective observational study of patients diagnosed with ALS in our healthcare area, classified by phenotypes to assess their relationship with functional respiratory variables, gas exchange, and sleep-related breathing disorders. The search period was from 2014 to 2024. Data from 201 patients were analyzed. The overall mean incidence of ALS was 3.8 cases (95%CI: 3.3-4.3)/100,000 inhabitants/year, while the prevalence was 9.4 cases (95%CI: 7.8-11.1)/100,000 inhabitants. The results indicated that the spinal phenotype is the most common (49.3%), while the bulbar phenotype presented greater respiratory involvement, with a lower forced vital capacity (FVC) (86% [IQR: 66.5-98]) and greater nocturnal desaturation CT90 8% (IQR: 2.3-32.5%). Likewise, a prevalence of respiratory disorders during sleep was observed, with approximately 50% mild obstructive sleep apnea (OSA), 30% moderate, and 15% severe. Severe OSA was recorded in 8% of patients with spinal ALS, 14% of patients with bulbar ALS, and 17% with other forms of ALS. The disease significantly affects respiratory function, especially in the bulbar phenotype, and respiratory disturbances during sleep are common. The heterogeneity of ALS highlights the importance of a personalized approach to patient management.\n\nID: 41814574\nTitle: Oral Health in Amyotrophic Lateral Sclerosis: Feasibility of Oral Screening and Determinants of Poor Outcomes.\nAbstract: Oral hygiene represents a modifiable risk factor for systemic health and pulmonary complications yet is not routinely addressed in ALS care. This study aimed to examine the relationships between oral health, disease severity and determinants of health in people living with amyotrophic lateral sclerosis (pALS), and to identify key predictors of oral hygiene outcomes. Individuals with ALS completed an oral hygiene and bulbar screening during their multidisciplinary appointment. Disease demographics, determinants of health, oral health outcomes and bulbar disease outcomes were collected. Descriptives and one sample t-tests were performed to compare oral hygiene outcomes with healthy reference values. Multiple regression analyses were conducted to assess the relationship between disease demographics and oral health. Sixty-two pALS aged 64.0 (+/- 10.8), 40% female, 31% Hispanic/Latino and 37% bulbar onset disease were enrolled. Compared to healthy reference values, plaque index (M\u2009=\u20091.45, SD\u2009=\u20090.52, p\u2009<\u20090.0001), gingival index (M\u2009=\u20091.25, SD\u2009=\u20090.46, p\u2009<\u20090.0001) and bleeding on probing (M\u2009=\u200935.26%, SD\u2009=\u200926.1, p\u2009<\u20090.0001) were elevated in pALS. Lack of dental insurance was a significant predictor of bleeding on probing (BOP) (p\u2009=\u20090.001), plaque (p\u2009=\u20090.006) and gingival scores (p\u2009=\u20090.001). ALSFRS-R (p\u2009<\u20090.03) was also predictive of greater plaque, and care partner status (p\u2009<\u20090.04), and age (p\u2009<\u20090.02) were predictors BOP. Ethnicity and dysphagia severity were not significant predictors. Oral health screenings conducted during routine multidisciplinary visits identified periodontal disease in pALS, representing a feasible and immediately actionable pathway to improve oral care outcomes in pALS.\n\nID: 41738007\nTitle: KMT2B-related disorders in Austria: clinical features and long-term outcome after deep brain stimulation.\nAbstract: Since its initial description in 2016, DYT-KMT2B has emerged as one of the most common genetic causes of early-onset dystonia. Subsequent reports have expanded its phenotypic spectrum, frequently including neurodevelopmental features. Deep brain stimulation of the globus pallidus internus (GPi DBS) has become a therapeutic mainstay; however, most published data are based on single cases or short-term observations, and long-term outcomes remain poorly characterized. We report the clinical course and response to GPi DBS in nine patients with KMT2B variants prospectively followed at two Austrian national reference centers for rare movement disorders. Long-term follow-up data (range: 5-20 years) were available for six patients. Clinical features and treatment outcomes were compared with previously published cohorts. Non-motor features such as developmental delay, intellectual disability, and epilepsy were more frequent in our cohort than in earlier reports. All patients developed generalized dystonia and bulbar involvement over time, emphasizing the progressive nature of the disease. Despite secondary symptom worsening during long-term follow-up, GPi DBS preserved ambulation in three patients and enabled sustained recovery of walking ability in two, maintaining functional independence. Surgical correction of foot deformities further supported mobility. Notably, KMT2B variants were identified upon genetic re-evaluation in two patients previously diagnosed with dyskinetic cerebral palsy. Our long-term data underscore the progressive but heterogeneous course of DYT-KMT2B. GPi DBS offers durable clinical benefits, particularly when initiated before loss of ambulation. Early surgical intervention and multidisciplinary management are essential to optimize long-term outcomes.\n\nID: 41714394\nTitle: [Motor neuron diseases from a radiological perspective : Focus on amyotrophic lateral sclerosis].\nAbstract: Motor neuron diseases (MND) affect the upper and/or lower motor neurons. Radiological diagnostics primarily serve to systematically exclude treatable mimics and support the clinical and electrophysiological diagnosis. The focus is on amyotrophic lateral sclerosis (ALS); supplementary progressive muscular atrophy (PMA, purely lower motor neuron, LMN disease) and spinal muscular atrophy (SMA). Which imaging signs support the diagnosis of ALS, how do electromyography/magnetic resonance imaging (EMG/MRI) fit into the Gold Coast criteria and which other motor neuron diseases are relevant? Overview of clinical criteria (Gold Coast), genetics and typical MRI findings of the brain, spinal cord and musculature. Gold Coast core: progressive motor deterioration, upper motor neuron (UMN) and LMN signs in \u2265\u202f1 region or LMN in \u2265\u202f2\u00a0regions and exclusion of alternative causes. susceptibility-weighted imaging (SWI) motor band sign as UMN marker; T2/fluid-attenuated inversion recovery (FLAIR) hyperintensities along the corticospinal tract with low sensitivity, moderate specificity; T1 bright tongue as an indication of chronic denervation in bulbar involvement. EMG: detection of subclinical LMN involvement, sometimes limited in UMN-dominant/bulbar courses. PMA: Pure purely LMN symptoms, often continuum to ALS. SMA: Autosomal autosomal recessive (SMN1 deletion). The diagnosis remains primarily clinical; EMG and MRI are supportive. The radiological priority is the exclusion of mimics. The UMN markers increase diagnostic certainty in the context of clinical/EMG findings but do not replace them. Clear findings facilitate classification according to Gold Coast. The PMA and SMA require careful differential diagnostics; characteristic MRI patterns support progression and treatment planning. HINTERGRUND: Motoneuronerkrankungen (MNE) betreffen das obere (UMN) und/oder untere (LMN) Motoneuron. Die radiologische Diagnostik dient prim\u00e4r dem strukturierten Ausschluss behandelbarer Mimics und der Unterst\u00fctzung der klinischen und elektrophysiologischen Diagnose. Fokus: amyotrophe Lateralsklerose (ALS); erg\u00e4nzend progressive Muskelatrophie (PMA) und spinale Muskelatrophie (SMA). Welche bildgebenden Zeichen st\u00fctzen die ALS-Diagnose, wie ordnen sich Elektromyographie (EMG)/Magnetresonanztomographie (MRT) in die Gold-Coast-Kriterien ein, und welche weiteren MNE sind relevant? \u00dcbersicht klinischer Kriterien (Gold-Coast), Genetik und typischer MRT-Befunde von Gehirn, R\u00fcckenmark und Muskulatur. Gold-Coast-Kern: progrediente motorische Verschlechterung, UMN- und LMN-Zeichen in \u2265\u202f1 Region oder LMN in \u2265\u202f2\u00a0Regionen, Ausschluss alternativer Ursachen. Als Bildgebungsverfahren kommen die MRT (\u201emotor-band sign\u201c) in der Suszeptibilit\u00e4tswichtung (SWI) als UMN-Marker; T2/FLAIR-Hyperintensit\u00e4ten entlang des kortikospinalen Trakts mit geringer Sensitivit\u00e4t und moderater Spezifit\u00e4t; \u201eT1-Bright-Tongue\u201c als Hinweis auf chronische Denervation bei bulb\u00e4rer Beteiligung. EMG: Nachweis subklinischer LMN-Beteiligung, bei UMN-dominanten/bulb\u00e4ren Verl\u00e4ufen teils limitiert. PMA: reine LMN-Symptomatik, h\u00e4ufig Kontinuum zur ALS. SMA: autosomal-rezessiv (SMN1-Deletion). Die Diagnose bleibt prim\u00e4r klinisch; EMG und MRT sind unterst\u00fctzend. Radiologische Priorit\u00e4t ist der Ausschluss von Mimics. UMN-Marker erh\u00f6hen im Kontext von Klinik/EMG die diagnostische Sicherheit, ersetzen diese jedoch nicht. Klare Befundformulierung erleichtern die Zuordnung nach Gold-Coast. PMA und SMA erfordern differenzialdiagnostische Sorgfalt; charakteristische MRT-Muster unterst\u00fctzen Verlauf und Therapieplanung.\n\nID: 41685589\nTitle: Cognitive Dysfunction Is Associated With an Underestimation of Respiratory Function in ALS.\nAbstract: The association between low forced vital capacity (FVC) and cognitive impairment in ALS is ambiguous; it could be due to respiratory dysfunction and/or poor effort from cognitive deficits. We used the objective, non-volitional phrenic nerve motor response amplitude (PAmp) to clarify how cognitive status affects the relationship between diaphragmatic strength and FVC. This retrospective study included 73 patients with ALS followed in our clinic. FVC and PAmp were measured, and cognitive status was assessed with the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Regression models tested for associations between FVC and distinct ECAS domains and whether these domains influenced the PAmp-FVC relationship. PAmp (\u03b2\u2009=\u20090.58, p\u2009=\u20090.001) and its interaction with an abnormal ECAS's Executive score (\u03b2\u2009=\u2009-0.20, p\u2009<\u20090.045) were significant predictors of FVC. The latter indicated that patients with abnormal executive function had lower FVC than cognitively normal patients at similar PAmp values. Moreover, in patients with abnormal executive function, a reduction in PAmp was associated with a shallower decline in FVC. Severe bulbar dysfunction was also negatively associated with FVC (\u03b2\u2009=\u2009-0.22, p\u2009=\u20090.024). FVC may underestimate respiratory capacity in cognitively impaired patients; therefore, we recommend non-volitional measures when evaluating ALS patients with executive dysfunction.\n\nID: 41681063\nTitle: Ultrasonographic Measurements of Tongue Thickness and Swallowing Dysfunction in Amyotrophic Lateral Sclerosis: A Feasibility Study.\nAbstract: To explore whether ultrasonographic measurements of tongue thickness are associated with swallowing function and related clinical domains in patients with amyotrophic lateral sclerosis (ALS), this feasibility study was conducted. Few studies have examined the usefulness of ultrasonographic tongue thickness measurement in patients with ALS, but its association with physiological measures remains unclear. Ten patients with ALS underwent tongue thickness measurement using ultrasonography. Clinical assessments including the Korean version of the ALS Functional Rating Scale-Revised (K-ALSFRS-R), Functional Oral Intake Scale (FOIS), Eating Assessment Tool-10 (EAT-10), Dysphagia Handicap Index, Korean version of the Swallowing Quality of Life Questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), handgrip strength, and bioelectrical impedance analysis for skeletal muscle index (SMI) were performed. Swallowing physiology was evaluated using the Modified Barium Swallow Impairment Profile (MBSImP), Penetration-Aspiration Scale. Simple and partial Pearson's correlation analyses as well as univariate regression were performed with adjustments for age, sex, and body mass index (BMI). Tongue thickness showed significant associations with multiple functional and systemic measures in the unadjusted analyses, including FOIS, EAT-10, MNA-SF, BMI, SMI, K-ALSFRS-R. After adjustment, the most consistent associations were observed with the MBSImP oral, pharyngeal, and combined phase scores. Tongue ultrasonography may serve as a radiation-free method to preliminarily assess bulbar involvement in ALS. Tongue thickness was most specifically associated with dysphagia outcomes, particularly MBSImP. Given the feasibility design and small sample size, larger longitudinal studies are warranted to confirm its clinical utility in monitoring the progression of dysphagia in patients with ALS.\n\nID: 41677019\nTitle: Four decades of ALS care: a retrospective study of epidemiology, clinical course and changes in management.\nAbstract: Several interventions have been introduced for amyotrophic lateral sclerosis (ALS) in recent decades, and population-level studies investigating their use and impact are needed. This study describes the epidemiology, disease trajectory, and changes in clinical management of ALS in a county of Norway over a 38-year period. We conducted a retrospective chart review of all ALS cases diagnosed between 1986 and 2024 in Tr\u00f8ndelag county, Norway. Data were extracted from medical records using a standardized electronic case report form. Patients were stratified by time of diagnosis into four groups. A total of 429 patients were included (56% male). Median age at symptom onset was 68\u2009years. The age-standardized incidence of ALS was 3.32 per 100,000 person-years (95%CI 2.90-3.74) and increased over time (p = 0.002). Bulbar onset occurred in 38% of cases. Median diagnostic delay was 13\u2009months (95%CI 12-14), without significant improvement over time. Median survival was 28\u2009months (95%CI 26-31) from symptom onset, shorter among bulbar-onset patients. Use of riluzole, percutaneous endoscopic gastrostomy, and noninvasive ventilation (NIV) increased over the study period, whereas median survival remained stable. Emergency initiation of ventilation occurred in 25% (NIV n\u2009=\u200941/167) and 89% (invasive ventilation n\u2009=\u200916/18) of cases in which these treatment modalities were used. This comprehensive regional study reveals a rising incidence of ALS in Tr\u00f8ndelag, with increased adoption of supportive interventions over time.\n\nID: 41661021\nTitle: [Combination of amyotrophic lateral sclerosis with Alzheimer's disease].\nAbstract: The combination of amyotrophic lateral sclerosis (ALS) with Alzheimer's disease is rare. Currently, it is unclear whether such comorbidity is an accidental coincidence or a manifestation of a specific pathological process. A case of simultaneous occurrence of classic symptoms of the bulbar form of ALS and Alzheimer's disease is presented. The possible mechanisms of the combination of two diseases are analyzed. \u0421\u043e\u0447\u0435\u0442\u0430\u043d\u0438\u0435 \u0431\u043e\u043a\u043e\u0432\u043e\u0433\u043e \u0430\u043c\u0438\u043e\u0442\u0440\u043e\u0444\u0438\u0447\u0435\u0441\u043a\u043e\u0433\u043e \u0441\u043a\u043b\u0435\u0440\u043e\u0437\u0430 (\u0411\u0410\u0421) \u0441 \u0431\u043e\u043b\u0435\u0437\u043d\u044c\u044e \u0410\u043b\u044c\u0446\u0433\u0435\u0439\u043c\u0435\u0440\u0430 \u0432\u0441\u0442\u0440\u0435\u0447\u0430\u0435\u0442\u0441\u044f \u0440\u0435\u0434\u043a\u043e. \u0412 \u043d\u0430\u0441\u0442\u043e\u044f\u0449\u0435\u0435 \u0432\u0440\u0435\u043c\u044f \u043d\u0435\u044f\u0441\u043d\u043e, \u044f\u0432\u043b\u044f\u0435\u0442\u0441\u044f \u043b\u0438 \u0442\u0430\u043a\u0430\u044f \u043a\u043e\u043c\u043e\u0440\u0431\u0438\u0434\u043d\u043e\u0441\u0442\u044c \u0441\u043b\u0443\u0447\u0430\u0439\u043d\u044b\u043c \u0441\u043e\u0432\u043f\u0430\u0434\u0435\u043d\u0438\u0435\u043c \u0438\u043b\u0438 \u043f\u0440\u043e\u044f\u0432\u043b\u0435\u043d\u0438\u0435\u043c \u043e\u0441\u043e\u0431\u043e\u0433\u043e \u043f\u0430\u0442\u043e\u043b\u043e\u0433\u0438\u0447\u0435\u0441\u043a\u043e\u0433\u043e \u043f\u0440\u043e\u0446\u0435\u0441\u0441\u0430. \u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u0441\u043b\u0443\u0447\u0430\u0439 \u043e\u0434\u043d\u043e\u0432\u0440\u0435\u043c\u0435\u043d\u043d\u043e\u0433\u043e \u0440\u0430\u0437\u0432\u0438\u0442\u0438\u044f \u043a\u043b\u0430\u0441\u0441\u0438\u0447\u0435\u0441\u043a\u0438\u0445 \u0441\u0438\u043c\u043f\u0442\u043e\u043c\u043e\u0432 \u0431\u0443\u043b\u044c\u0431\u0430\u0440\u043d\u043e\u0439 \u0444\u043e\u0440\u043c\u044b \u0411\u0410\u0421 \u0438 \u0431\u043e\u043b\u0435\u0437\u043d\u0438 \u0410\u043b\u044c\u0446\u0433\u0435\u0439\u043c\u0435\u0440\u0430. \u041f\u0440\u043e\u0430\u043d\u0430\u043b\u0438\u0437\u0438\u0440\u043e\u0432\u0430\u043d\u044b \u0432\u043e\u0437\u043c\u043e\u0436\u043d\u044b\u0435 \u043c\u0435\u0445\u0430\u043d\u0438\u0437\u043c\u044b \u0441\u043e\u0447\u0435\u0442\u0430\u043d\u0438\u044f \u0434\u0432\u0443\u0445 \u0437\u0430\u0431\u043e\u043b\u0435\u0432\u0430\u043d\u0438\u0439.\n\nID: 41633603\nTitle: [Analysis of early complications and risk factors in patients with amyotrophic lateral sclerosis after percutaneous endoscopic gastrostomy].\nAbstract: To explore risk factors of early complications (\u226414 days) and the clinical characteristics in patients with amyotrophic lateral sclerosis (ALS) after percutaneous endoscopic gastrostomy (PEG). Patients diagnosed with ALS who underwent first PEG insertion between January 2011 and December 2020 were eligible. Medical records were retrospectively reviewed to determine clinical characteristics and outcomes (\u226414 days) of patients who underwent the pull type PEG. Grouping was performed based on the presence and severity of complications, and SPSS 27.0 statistical software was used for data analysis. Finally, Logistic regression model was applied for multivariate factor analysis of risk factors related to complications. In the study, 192 cases of PEG were all successfully completed, with 97 (51%) males, mean age of ALS onset disease (55\u00b111) years and 93 (48%) bulbar onset symptoms included. Complications occurred in 40 (21%) cases after PEG within 14 days, all of which had fever, including 16 cases without clear infection focus, 18 cases of respiratory tract infections, and 6 cases of fistula site infections. In the study, 13 (7%) cases had major complications, including 11 cases of respiratory tract infection and 2 cases of stoma infection. Two cases of respiratory tract infection died due to respiratory failure, and the remaining 11 cases recovered after upgraded antibiotic. No complications, such as tube dislodgement, benign pneumoperitoneum, hemorrhage or buried bumper syndrome occurred. The operation time and postoperative hospital stay were longer in the complication group than in the non-complication group [(16\u00b15) min vs. (13\u00b15) min, P < 0.001; 6 (5, 9) d vs. 5 (3, 7) d, P=0.009]. Compared with the mild complication group, the creatinine and triglyceride in the major complication group were significantly lower [(46.5\u00b116.2) \u03bcmol/L vs.(66.8\u00b116.4) \u03bcmol/L, P\uff1c0.001; (1.1\u00b10.5) mmol/L vs.(1.6\u00b10.7) mmol/L, P=0.038], and the operation time was significantly longer [(20\u00b15) min vs. (15\u00b15) min, P=0.002]. Further, Logistic regression model analysis revealed that the operation time was also independent associated with complications (OR=1.132, 95%CI: 1.051-1.220, P=0.001). PEG was a reliable method for ALS patients to put nutrition tube. Postoperative fever was the most common complications.

Myocarditis, myositis, and myasthenia gravis (MMM) overlap syndrome is a rare, highly morbid complication with high mortality. Most cases develop early in therapy, sometimes after a single dose. CASE REPORT A 73-year-old man with resected stage IIIC malignant melanoma presented 4 weeks after his first dose of adjuvant nivolumab with progressive weakness, gait instability, dyspnea, and dark-colored urine. Workup revealed markedly elevated troponin (11 162 ng/L), creatine kinase (5518 IU/L), and transaminases (aspartate transaminase 614 IU/L, alanine transaminase 497 IU/L), with new right bundle branch block on electrocardiography. ICI-associated myocarditis, myositis, and hepatitis were diagnosed; high-dose intravenous methylprednisolone was initiated. He subsequently developed diplopia, ptosis, bulbar weakness, and respiratory compromise from myasthenia gravis, prompting plasmapheresis and pyridostigmine. He improved with escalating immunosuppression and was discharged on oral prednisone and pyridostigmine after 16 days. Nivolumab was permanently discontinued. Two and a half weeks later, he had a fatal out-of-hospital cardiac arrest. CONCLUSIONS This case illustrates the severe and unpredictable course of MMM overlap syndrome after a single dose of nivolumab. Despite early aggressive immunosuppression and apparent recovery, the patient had a delayed fatal cardiac event. Given the risk of relapse during corticosteroid taper, structured post-discharge cardiac surveillance with serial troponin and ambulatory rhythm monitoring may help detect subclinical activity or arrhythmia. Prospective studies are needed to define optimal monitoring and identify predictors of late mortality.\n\nID: 42433772\nTitle: Acute quadriparesis revealing Gitelman syndrome: a case report.\nAbstract: Gitelman syndrome (GS) is a rare autosomal recessive renal tubulopathy caused by SLC12A3 gene mutations, leading to hypokalemia, metabolic alkalosis, hypomagnesemia, and hypocalciuria. Its estimated prevalence ranges from 1 to 10 per 40\u00a0000 individuals worldwide, with a carrier frequency approaching 1%, underscoring its potential public health relevance despite underdiagnosis. This case highlights a rare presentation of GS with acute quadriparesis mimicking neurological emergencies, emphasizing the risk of misdiagnosis in acute care settings. A 30-year-old female presented with acute-onset fever, vomiting, and progressive quadriparesis. Examination revealed flaccid paralysis (power: 2/5), areflexia, and bulbar weakness. Critical biochemical findings included severe hypokalemia (K+:\u00a01.6\u00a0mmol/l), hypomagnesemia (1.19 mg/dl), metabolic alkalosis (pH: 7.48, HCO3 -: 32 mEq/l), hypocalciuria (6.43 mg/24\u00a0h), low urinary potassium, and elevated serum renin. This case demonstrates an intercurrent illness that precipitated acute decompensation in previously undiagnosed GS, leading to profound weakness mimicking Guillain-Barr\u00e9 syndrome, periodic paralysis and Bartter syndrome. The key to diagnosis lies in recognizing the distinctive biochemical triad of hypokalemia, hypomagnesemia, and hypocalciuria with renal potassium wasting. Although genetic testing for SLC12A3 mutations remains the diagnostic gold standard, it is often unavailable in resource-limited settings, making biochemical recognition crucial. GS is a great mimicker that can present with acute severe paralysis. Clinicians must include it in the differential for unexplained hypokalemia and metabolic alkalosis, as prompt recognition and management with magnesium and potassium supplementation are crucial to prevent life-threatening arrhythmias, recurrent paralysis and reduce long-term morbidity.\n\nID: 42421675\nTitle: Ceftriaxone-Resistant Escherichia coli Sepsis in an Infant With Spinal Muscular Atrophy Type 1 Receiving Risdiplam: A Case Report.\nAbstract: Even in the risdiplam era, infants with SMA type 1 remain vulnerable to severe resistant infections because respiratory and bulbar weakness persist. Early cultures, susceptibility-guided antibiotics, airway-clearance measures, ventilatory support, and multidisciplinary PICU care are crucial to stabilize sepsis, prevent respiratory deterioration, and improve outcomes in this fragile population overall.\n\nID: 42383533\nTitle: Presynaptic Congenital Myasthenic Syndromes.\nAbstract: Presynaptic congenital myasthenic syndromes (CMS) encompass a large number of rare neurologic disorders caused by impaired release of acetylcholine (ACh) from motor nerve terminals. There are two main groups of presynaptic CMS: one in which the amount of ACh in synaptic vesicles (SV) is diminished and another in which the mechanism of synaptic vesicle release is impaired. The latter is often referred to as a congenital Lambert-Eaton myasthenic syndrome (LEMS). Presynaptic CMS, like other forms of CMS, is primarily characterized by muscle weakness and fatigue, but is often associated with additional manifestations of central and autonomic nervous system involvement, including episodic apneas, cognitive delay, seizures, and gastrointestinal complications. The most common causes of presynaptic CMS are recessive and dominant mutations in genes encoding proteins participating in the mechanisms of ACh synthesis and SV release. However, at times gene mutations can result in more complex pathogenic mechanisms. The most effective treatment of these conditions is prevention of potentially fatal episodes of apnea and other respiratory complications resulting from bulbar weakness. Pharmacologic treatments are also useful; however, in many cases the response is incomplete, and in other mild cases there is improvement with age that obviates the need for pharmacologic interventions. Preclinical studies in animal models of presynaptic CMS using targeted gene therapies are promising but these new therapies will not be available in the near future.\n\nID: 42367493\nTitle: Progressive Bulbar Weakness in an Older Male With Suspected Double-Seronegative Myasthenia Gravis Culminating in Myasthenic Crisis: A Case Report.\nAbstract: Myasthenia gravis is a rare autoimmune disorder affecting the neuromuscular junction, causing muscle weakness that worsens with use and improves with rest. While it is typically diagnosed through\u00a0antibody tests or electrophysiological testing, a smaller subset of the population is seronegative or may have inconclusive electrophysiological results. In emergent presentations, seronegative myasthenia gravis is a challenge to diagnose clinically, making it imperative to identify it early to ensure proper management and treatment. Here, we present the case of an older male with a complex medical history and suspected seronegative myasthenia gravis who through the course of his admission experienced myasthenic crisis necessitating treatment with both intravenous immunoglobulin and plasmapheresis.\n\nID: 42318512\nTitle: Efficacy and safety of pyrimidine nucleos(t)ide therapy in thymidine kinase 2 deficiency.\nAbstract: Thymidine kinase 2 deficiency (TK2d) (MIM 609560) is an ultra-rare, autosomal recessive mitochondrial myopathy caused by TK2 variants, leading to mitochondrial DNA depletion and/or multiple deletions. People with thymidine kinase 2 deficiency experience progressive myopathy, bulbar weakness and respiratory insufficiency, often losing the ability to walk, eat and breathe independently. Doxecitine and doxribtimine represents the first approved treatment for patients with thymidine kinase 2 deficiency with age of symptom onset \u226412 years by the US Food and Drug Administration and the European Medicines Agency; previously, disease management was limited to supportive care. We investigated the efficacy and safety of pyrimidine nucleos(t)ide therapy in thymidine kinase 2 deficiency. Patients treated with pyrimidine nucleos(t)ides were pooled from retrospective (NCT03701568, NCT05017818) and prospective (NCT03845712) studies and company-supported Expanded Access Programs. Untreated patients were pooled from literature reviews and a retrospective chart review study (NCT05017818). Patient subgroups were stratified by age of thymidine kinase 2 deficiency symptom onset (\u226412 years and >12 years). The primary outcome was survival in 50th-percentile matched pairs of treated and untreated patients. Other outcomes included status of developmental motor milestones, ventilatory and feeding tube support, and safety. In total, 218 patients were included (treated: 104; untreated: 114). Baseline demographics and characteristics were comparable between subgroups. Most patients had an age of symptom onset \u226412 years [treated: 82/104 (78.8%); untreated: 93/114 (81.6%)]. In the age-of-symptom-onset-\u226412-years subgroup, restricted mean survival time (95% confidence interval) was 29.2 (28.2, 30.3) years over the 30 years after symptom onset for treated patients and 14.4 (11.1, 17.6) years for untreated patients. Loss of \u22651 acquired motor milestone was more frequent before treatment start than after. Substantially more patients regained \u22651 lost motor milestone after treatment start than before. Ventilatory and feeding support were used across all age-of-symptom-onset subgroups, but some patients reduced or discontinued support after starting treatment and fewer patients initiated support after treatment start than before. Most treatment-emergent adverse events (TEAEs) did not lead to discontinuation. The most frequent TEAE was diarrhoea [43/50 patients (86.0%)], which was generally mild or moderate and resolved with dose reduction. Serious TEAEs occurred in 28/50 patients (56.0%); few were considered to be drug related [4/50 (8.0%)]. In total, 3/67 patients (4.5%) experienced a fatal serious TEAE, which were not considered to be drug related. These findings indicate that pyrimidine nucleos(t)ide therapy improves survival and functional outcomes in people with thymidine kinase 2 deficiency, especially those with age of symptom onset \u226412 years, and has an acceptable safety profile.\n\nID: 42233901\nTitle: Triple M Overlap Syndrome After Immune Checkpoint Inhibitors: A Case Series of a High-Mortality Phenotype.\nAbstract: Immune checkpoint inhibitor-associated Triple M overlap syndrome (TMOS), defined by concurrent myocarditis, myositis, and myasthenia gravis, is a rare but life-threatening immune-related adverse event. We report a single-center case series of 8 consecutive patients who developed TMOS during immune checkpoint inhibitor therapy for solid malignancies between 2023 and 2025. Median age was 76 years and median time to symptom onset was 14.5 days after exposure. All patients had myositis symptoms; 5 required mechanical ventilation and 1 subsequently required tracheostomy. Cardiac involvement was characterized by troponin elevation and frequent electrical abnormalities, including complete atrioventricular block, ventricular tachyarrhythmias, and bundle branch block, despite preserved left ventricular systolic function on imaging. Corticosteroid monotherapy was insufficient in practice, and all patients required additional immunomodulatory therapy. TMOS requires early recognition, close monitoring, and rapid multidisciplinary escalation of care.\n\nID: 42228597\nTitle: The anatomy of concealed awareness: lessons from partial locked-in syndrome.\nAbstract: Partial locked-in syndrome (PLIS) is a rare stroke presentation in which preserved consciousness is masked by severe motor impairment, potentially leading to misinterpretation as encephalopathy. We report a patient in her early seventies with vascular risk factors and a prior pontine infarct who presented with acute quadriplegia and mutism. Initial clinical impressions raised concern for altered mental status. However, subsequent neurological examination demonstrated preserved awareness, with consistent eye tracking and command following through head movements. Examination showed bifacial and bulbar weakness, severe dysarthria, and minimal right arm movement. MRI demonstrated new infarcts in the left cerebral peduncle, posterior limb of the internal capsule, thalamus, and temporal lobe, superimposed on a prior pontine lesion. This distributed but strategically located pattern of injury affected bilateral corticospinal pathways and explained the profound motor impairment despite preserved consciousness. This case highlights how PLIS may mimic encephalopathy in the acute care setting and underscores the importance of structured bedside assessment for detecting preserved awareness in mute or immobile patients. Early recognition has implications for airway management, stroke evaluation, communication strategies, and prognostic counseling.\n\nID: 42131123\nTitle: High-Dependency Care Without Mechanical Ventilation for Severe Guillain-Barr\u00e9 Syndrome in a Rural Low-Income Setting.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) is a major cause of neuromuscular respiratory failure globally. In many low-income settings, access to mechanical ventilation and disease-modifying therapy is limited. We describe the management of a young woman with rapidly progressive GBS and bulbar weakness in a mission hospital in northern Madagascar without access to intensive care facilities, invasive ventilation or immunotherapy. Respiratory failure was managed using a structured high-dependencyunit (HDU) framework combining noninvasive respiratory support with intensive nursing care, physiotherapy, regular repositioning and close nurse-led observation. The patient survived the acute phase, regained swallow and speech by Day 8 and was discharged from HDU on Day 15. At 1-year follow-up, she had recovered full upper limb strength with residual lower limb weakness. This case highlights the potential for structured supportive care in an HDU to sustain life in clinically significant neuromuscular respiratory failure when definitive critical care resources are unavailable.\n\nID: 42078235\nTitle: Systemic Barium Toxicity Manifesting As Acute Hypokalemic Paralysis and Respiratory Failure Following a Firework Injury.\nAbstract: We present the case of a 63-year-old male who sustained a penetrating soft tissue injury to the right thigh from a commercial firework. Following uncomplicated surgical debridement and discharge, the patient returned within hours exhibiting rapidly progressive ascending paralysis, bulbar weakness, and respiratory failure requiring intubation. Laboratory evaluation revealed profound hypokalemia (1.4 mmol/L), hypophosphatemia, and rhabdomyolysis. The clinical presentation, coupled with the patient's report of the firework emitting a green flare, is most consistent with acute barium toxicity. Formal toxicologic confirmation was not available; however, the clinical constellation, mechanism of injury, and rapid response to electrolyte repletion strongly support this diagnosis. Barium salts, commonly used in pyrotechnics to produce green coloration, can induce systemic toxicity by competitively blocking potassium channels, causing a widespread intracellular shift of potassium. This case highlights the rare but life-threatening systemic toxicity associated with soluble barium salts and the importance of considering toxicologic etiologies in trauma patients presenting with unexplained neurological collapse.\n\nID: 42043041\nTitle: Clinical Characteristics and Outcomes of Asian Coral Snake Bites in Thailand: A Retrospective Cohort Study.\nAbstract: Asian coral snakes are distributed throughout Southeast Asia, including Thailand, but clinical data on their envenomation remain limited. Using a 10-year retrospective dataset from the Ramathibodi Poison Center, we investigated the epidemiology, clinical characteristics, management, and outcomes of Asian coral snake envenomation in Thailand. Patient demographics, clinical and laboratory data, treatments, and outcomes were analyzed descriptively. Fifty-two patients were included. Sinomicrurus macclellandi was the most frequently reported species. Most bites occurred during the rainy season and involved the lower extremities. Clinical manifestations were predominantly mild and localized. No cases of systemic neurotoxicity, bulbar weakness, respiratory compromise, or death were observed. Laboratory results were generally within normal limits. Two patients developed anaphylaxis, which resolved with standard emergency treatment, while two experienced severe pain. Calliophis intestinalis lineata was associated with a higher proportion of tachycardia at presentation and longer hospitalization. No patients required mechanical ventilation or antivenom therapy. Supportive care and short-term hospital observation are generally sufficient in confirmed cases. The median duration of hospitalization was 1-3 day. Local manifestations were the predominant clinical findings following Asian coral snake envenomation in Thailand, and systemic neurotoxicity was not observed. These findings differ from reports of Micrurus envenomation, which primarily involve New World coral snakes, whereas the species implicated in Thailand belong to Old World genera.\n\nID: 41938285\nTitle: A Case of Myopathic Dysphagia Secondary to Thyrotoxicosis.\nAbstract: Myopathic dysphagia is a rare manifestation of thyrotoxicosis. Dysphagia may be isolated or may be associated with preceding proximal myopathy. We describe a 70-year-old man with newly diagnosed Graves' disease who presented with acute dysphagia with both liquids and solids for 3 weeks, with free thyroxine >73 pmol/L (reference range 8-16 pmol/L), free triiodothyronine >40 pmol/L (reference range 3.5-6.0 pmol/L), thyroid-stimulating hormone <0.01 mIU/L (reference range 0.45-4.50 mIU/L), and thyroid-stimulating hormone receptor antibody 28.6 IU/L (reference range 0.0-1.0 IU/L). This was associated with heat intolerance, palpitations, diarrhea, proximal weakness, and weight loss.A video fluoroscopy study confirmed moderate oropharyngeal dysphagia. Evaluation was done to exclude other causes including mechanical compression, neuromuscular causes, and malignancy.The patient's dysphagia improved with carbimazole doses of up to 30 mg twice daily, and propranolol doses of up to 20 mg 3 times daily, titrated as thyrotoxicosis improved. He became euthyroid after 5 weeks of treatment, and had clinical improvement in swallowing by 8.5 weeks, improving from requiring nasogastric tube feeding to tolerating regular diet and thin fluids. We discuss differential diagnosis to consider and exclude, and the pathophysiology involved in myopathic dysphagia. Based on case reports in literature, patients responded well with high doses of thionamides and beta-blockers. Our patient's dysphagia resolved rapidly with normalization of free thyroxine and free triiodothyronine. It is important to render the patient euthyroid as soon as possible to minimize risks of aspiration, pneumonia, and other complications.\n\nID: 41839317\nTitle: Guillain-Barr\u00e9 syndrome in pregnancy: A systematic review of published case reports and case series with obstetric and neonatal outcomes.\nAbstract: Guillain-Barr\u00e9 syndrome is a rare but clinically significant complication in pregnancy, associated with high maternal and perinatal risks. Diagnosis may be delayed because early neurological symptoms overlap with common pregnancy-related complaints. Although case reports describe variable maternal severity and neonatal outcomes, evidence is fragmented, and no prior systematic review has synthesized these data. To systematically review published case reports and series of Guillain-Barr\u00e9 syndrome (GBS) with onset during pregnancy, focusing on maternal disease course, obstetric management, and neonatal outcomes. A systematic revie w was conducted according to PRISMA 2020 guidelines and registered in PROSPERO (CRD420251127698). PubMed, Embase, and Scopus were searched to August 2025 for case reports and series of pregnancy-onset GBS. Eligible studies required a confirmed diagnosis and at least 1 maternal, obstetric, or neonatal outcome. A total of 90 studies comprising 101 cases were included. Mean maternal age was 27.3 years, with symptom onset most frequent in the third trimester (52.5%). Preceding infection was reported in nearly half. Limb weakness (98%) and areflexia (87.6%) were predominant, and acute inflammatory demyelinating polyneuropathy accounted for 70% of subtypes. ICU admission occurred in 64%, and mechanical ventilation in 45%. Bulbar weakness (OR 5.29, P=.001) and autonomic dysfunction (OR 7.17, P<.001) were strongly predictive of ICU requirement. Neurological recovery was complete in 35%, partial in 59.4%, with maternal mortality of 5.2%. Obstetric outcomes showed cesarean delivery in 54.8% and preterm birth in 36%. One-third of neonates were low birthweight, though overall survival was 85.6%. Third-trimester onset correlated with higher risks of preterm delivery and maternal respiratory compromise, underscoring the vulnerability of late gestation. GBS in pregnancy carries substantial maternal morbidity and obstetric risk. Early recognition and multidisciplinary care are crucial. Despite high neonatal survival, risks of preterm birth and maternal ventilation remain significant.\n\nID: 41764572\nTitle: Successful prehospital resuscitation of a young female patient with myasthenia gravis experiencing cardiopulmonary arrest due to complete airway obstruction: a case report and review of the literature.\nAbstract: Patients with myasthenia gravis are at high risk of fatal airway complications due to impaired swallowing mechanics. We present a prehospital resuscitation case involving complete airway obstruction leading to cardiopulmonary arrest in a young patient with myasthenia gravis. A 21-year-old Han Chinese female patient with a reported history of myasthenia gravis developed sudden respiratory arrest during oral intake. The diagnosis of myasthenia gravis was initially provided by on-scene witnesses (classmates), and later confirmed by family who reported her medication regimen. Prehospital interventions-including modified Heimlich maneuvers, rapid endotracheal intubation, and advanced cardiac life support-achieved return of spontaneous circulation within 10\u00a0minutes. Persistent hypoxia and hemodynamic instability were managed during transport. The patient was transferred to the hospital intensive care unit but subsequently died due to the consequences of prolonged cerebral hypoxia. Myasthenia-gravis-associated bulbar weakness predisposes patients to catastrophic aspiration events. This case highlights three critical prehospital strategies: (1) modified supine-position Heimlich maneuvers for intubated arrest patients, (2) time-critical airway clearance using direct laryngoscopy, and (3) multidisciplinary coordination between telemedicine dispatchers and field responders. Our findings highlights the unique challenges of managing airway obstruction in patients with myasthenia gravis and proposes an integrated prehospital strategy for airway management. This case underscores that successful prehospital return of spontaneous circulation is possible in patients with myasthenia gravis with acute airway obstruction; however, prevention remains paramount due to the risk of fatal outcomes. It emphasizes the need for integrated prehospital strategies, patient education on aspiration risk, and protocolized airway algorithms for neuromuscular disorders.\n\nID: 41646374\nTitle: Axonal dying back of upper motor neurons in human ALS.\nAbstract: Patients with amyotrophic lateral sclerosis (ALS) present with arm, leg, or bulbar weakness with or without spasticity. While genetics plays a clear role in a subset of cases, it cannot explain why symptoms start focally or how upper (UMN) and lower motor neuron (LMN) systems are linked. Here, we examined the clinicopathological relationships between UMN and LMN disease in ten ALS patients. Detailed clinical assessments were obtained and tissues from the motor cortex, brainstem, and spinal cord were collected via a rapid autopsy protocol. Tissues were stained for UMN/LMN, myelin, axons, microglia, and pTDP43. Total RNA-sequencing was performed in the medulla, cervical, and lumbar spinal cords from each patient to identify pathways enriched at sites of disease onset. None of the patients had symptoms of frontotemporal dementia (FTD), but all had focal sites of clinical onset and spasticity, indicating both UMN and LMN involvement. Postmortem examination showed LMN degeneration and microglial activation were highest at sites of disease onset. In contrast, UMN degeneration of the corticospinal tract (CST) was present equally at all levels of the spinal cord up through the medulla, regardless of the site of disease onset. Surprisingly, there was no evidence of UMN degeneration of cortical motor neurons or their projecting axons above the brainstem. Similarly, while extensive pTDP43 aggregates were seen in degenerating LMNs, no pTDP43 aggregates were seen in UMN cell bodies or their axons. Mechanistically, RNA-sequencing implicated inflammatory pathways, especially at sites of disease onset. Our findings suggest that many ALS patients without FTD have a dying back of UMN axons, independent of the site of disease onset, which stops in the brainstem with preservation of cortical motor neurons and their proximal axons. Our findings suggest that UMN axonal degeneration can be directly triggered by LMN degeneration and inflammation.\n\nID: 41583497\nTitle: Efgartigimod combined with rituximab helps improve the symptoms and reduce the use of corticosteroids in patients with MuSK antibody-positive MG: a single case report.\nAbstract: Myasthenia gravis (MG) is an autoimmune disorder primarily affecting the neuromuscular junction. Muscle-specific receptor tyrosine kinase\u00a0antibody (MuSK-Ab)-mediated MG often presents with bulbar weakness and is prone to crisis. Currently, conventional treatments show limited efficacy in\u00a0MuSK-Ab-mediated MG, while rituximab therapy demonstrates favorable outcomes. We report a case of a patient who initially achieved symptom control with efgartigimod during an acute exacerbation but experienced symptom recurrence after subsequent rituximab treatment. Owing to poor tolerance to pyridostigmine and corticosteroids, and considering the established efficacy of efgartigimod in MuSK-Ab-positive MG, we opted for continued efgartigimod infusions. This approach quickly improved symptoms, achieved minimal symptom expression (MSE), and allowed faster tapering of corticosteroids and pyridostigmine. While multiple studies have demonstrated the efficacy and safety of efgartigimod, large-scale studies remain necessary to further evaluate the feasibility of combination therapy with rituximab in MuSK-Ab-positive MG.\n\nID: 41552140\nTitle: Seropositive Myasthenia Gravis Triggered by Lyme Disease: A Case Study of Molecular Mimicry.\nAbstract: Lyme disease, caused by Borrelia burgdorferi, is a multisystem infection that rarely produces neuromuscular complications beyond classic neuroborreliosis. Myasthenia gravis (MG) is an autoimmune disorder characterized by fatigable weakness due to acetylcholine receptor (AChR) antibodies. We describe a 74-year-old man with coronary artery disease, chronic kidney disease, and prostate cancer who developed progressive dysphagia, dysphonia, ptosis, and neck weakness. Initial attribution to medication-related angioedema delayed recognition. Neurological examination revealed bulbar weakness and fatigable ptosis. Electrodiagnostic testing confirmed post-synaptic neuromuscular junction dysfunction, and AChR antibody assays were strongly positive across binding, blocking, and modulating subtypes. Concurrent Lyme serologies were positive for immunoglobulin G and immunoglobulin M. The patient required intensive care monitoring and was treated with plasma exchange, intravenous ceftriaxone, prednisone, and pyridostigmine, with marked improvement. This case illustrates a rare coexistence of neuroborreliosis and seropositive MG, highlighting potential molecular mimicry between Borrelia antigens and AChR epitopes.\n\nID: 41548480\nTitle: Association of sleep disorder with bulbar weakness and short-term outcomes in myasthenia gravis.\nAbstract: Sleep disorder is increasingly recognized in myasthenia gravis (MG). However, its specific link to bulbar muscle weakness and short-term outcomes is not well established. This study aimed to investigate the prevalence of subjective sleep disorder (based on Pittsburgh Sleep Quality Index [PSQI] score) in a cohort of acetylcholine receptor (AChR) antibody-positive MG patients, and to explore its associations with bulbar muscle weakness, disease severity, and its value for the short-term outcome of MG. We conducted a prospective cohort study of 163 AChR-MG patients. Subjective sleep quality was assessed using the PSQI score. Disease severity was evaluated with MG Specific Activities of Daily Living (MG-ADL) score, the Quantitative MG (QMG) score, and Myasthenia Gravis Foundation of America (MGFA) classification. Univariate and multivariable logistic regression were used to identify independent risk factors and establish prediction model for outcome. The predictive values were evaluated by receiver operating characteristic (ROC) curves. Moreover, calibration analysis and decision curve analysis (DCA) of the model were performed. The median PSQI score was 7.0 (5.0, 9.0) and the prevalence of sleep disorder (PSQI > 5) was 73.6\u00a0%. Patients with bulbar weakness had significantly higher PSQI scores than those without (P < 0.001). PSQI score showed significant positive correlations with MG-ADL (r\u00a0=\u00a00.319, P < 0.001),QMG (r\u00a0=\u00a00.356, P < 0.001) in MG patients. A higher baseline PSQI score was identified as an independent risk factor for poor outcome at 6\u00a0months (odds ratio: 1.642 [95\u00a0% CI: 1.340-2.014], P < 0.001), with a area under curve (AUC) of 0.797. A predictive model combining PSQI score, bulbar weakness, and female gender demonstrated good discrimination, with a AUC of 0.840, a sensitivity of 0.688, and a specificity of 0.870. Poor sleep quality is highly prevalent in AChR-MG and was more serious in patients with bulbar weakness. PSQI score was an independent risk factor for poor short-term outcome. Routine assessment of sleep may aid in risk stratification and personalized management.\n\n\n\nID: 41487841\nTitle: Double Trouble: Guillain-Barr\u00e9 Syndrome (GBS) Presenting as Overlapping Miller Fisher Syndrome (MFS) and Pharyngeal-Cervical-Brachial (PCB) Variant.\nAbstract: Guillain-Barr\u00e9 Syndrome (GBS) is the leading cause of acute flaccid paralysis in India following the decline of poliomyelitis. Classical GBS typically presents with ascending symmetrical weakness and areflexia, while atypical variants, such as Miller Fisher Syndrome (MFS) and the Pharyngeal-Cervical-Brachial (PCB) variant, show distinct clinical patterns that are often under-recognized, particularly in resource-limited settings. This report describes a rare case of a 45-year-old previously healthy woman who developed progressive ophthalmoplegia, bulbar weakness, neck flexor weakness, and proximal upper limb weakness, along with areflexia, following a mild upper respiratory tract infection. Sensory function and lower limb motor strength remained intact. The differential diagnoses included brainstem stroke, myasthenia gravis, and diphtheritic polyneuropathy. Cerebrospinal fluid analysis revealed albuminocytologic dissociation, and nerve conduction studies showed a demyelinating sensorimotor polyneuropathy predominantly affecting the upper limbs. The presence of anti-GQ1b and anti-GT1a IgG antibodies supported an immune-mediated process. A diagnosis of GBS with overlapping MFS and PCB variants was established. The patient received a five-day course of intravenous immunoglobulin along with supportive management. Her neurological function gradually improved, with complete recovery noted at the three-month follow-up. This case highlights the importance of early recognition of overlapping GBS variants, especially in patients with cranial nerve and upper limb involvement. Greater clinical awareness and improved access to ganglioside antibody testing may facilitate earlier diagnosis and better outcomes. The coexistence of MFS and PCB variants also reinforces the concept of GBS as a spectrum disorder with shared underlying mechanisms.\n\nID: 41421983\nTitle: Dengue virus infection and Guillain-Barr\u00e9 syndrome: a systematic review of clinical characteristics, outcomes, and predictors of severity.\nAbstract: BACKGROUND: Dengue virus (DENV) is a mosquito-borne flavivirus causing significant morbidity in tropical and subtropical regions. While not classically neurotropic, DENV has been increasingly associated with neurological complications, including Guillain\u2013Barr\u00e9 syndrome (GBS). This review synthesizes evidence on epidemiology, clinical features, outcomes, and predictors of severity in dengue-associated GBS. METHODS: We systematically searched PubMed and Embase (April 2025) using terms for dengue and GBS. Eligible studies were case reports/series with individual-level data on laboratory-confirmed or clinically diagnosed dengue preceding GBS. RESULTS: Thirty-six publications describing 56 patients from Asia, Latin America, and other endemic regions were included. The mean age was 34.9 years (range 1.5\u201373), with 57% male. 95% had symptomatic dengue; thrombocytopenia occurred in 43%. Median latency from dengue onset to GBS was 7 days. Motor weakness was universal; facial palsy (32%), bulbar weakness (28.6%), sensory deficits (33.9%), and autonomic dysfunction (18%) were common. Electrophysiology showed AMSAN (33.9%), AIDP (32.1%), and AMAN (12.5%). Albuminocytologic dissociation was present in 62.5% of CSF samples. IVIG was administered in 76.7%, plasmapheresis in 14.3%; 25% required mechanical ventilation. Outcomes were favorable in most: 57% achieved full recovery, 32% partial recovery, and 5.4% mortality. CONCLUSIONS: Dengue-associated GBS resembles other post-infectious forms but shows a high proportion of axonal subtypes. Prognosis is generally good with standard therapy. Although severe cases, particularly those with thrombocytopenia, are more likely to require ICU care. Clinicians in endemic areas should maintain a high index of suspicion for GBS in the post-dengue period to enable timely diagnosis and management.\n\nID: 41366746\nTitle: Safety and efficacy of botulinum toxin injection for sialorrhea in amyotrophic lateral sclerosis: a systematic review and meta-analysis.\nAbstract: INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, with 80% of ALS patients experiencing bulbar weakness at some stage of the disease. ALS patients with bulbar weakness often suffer from troublesome sialorrhea. Botulinum toxin injection, as a neuromuscular blocker, has been widely used in the treatment of sialorrhea. This paper evaluates the safety and efficacy of botulinum toxin injections for the treatment of sialorrhea in ALS patients through a systematic review and meta-analysis. METHODS: A systematic review and meta-analysis was conducted by searching eight databases, including PubMed, EMBASE, and CNKI, up to April 13, 2025. Eligible randomized controlled trials and quasi-experimental studies were analyzed using Review Manager 5.4 and Stata software. RESULTS: Thirteen studies (2 RCTs, 11 quasi-experimental studies) with 130 ALS patients were included. Botulinum toxin significantly reduced sialorrhea and improved quality of life (Z\u2009=\u200910.98, p\u2009<\u20090.00001; RD\u2009=\u20090.82, 95% CI: 0.67\u20130.97). The treatment effect was independent of toxin type (p\u2009=\u20090.48), injection site (p\u2009=\u20090.17), and ultrasound guidance use (p\u2009=\u20090.44). CONCLUSION: Botulinum toxin appears to be a safe and effective option for managing sialorrhea in ALS patients, regardless of injection technique. However, given that most included studies were observational, further validation through high-quality RCTs is warranted. TRIAL REGISTRATION: This meta-analysis has been registered with Prospero, and the registration number is CRD420251029441. The registration period is April 9, 2025.\n\nID: 41158935\nTitle: Checkpoint Inhibitor-Associated Myasthenia-Myositis Overlap With Neuromuscular Respiratory Failure After Dual PD-L1 Plus CTLA-4 Checkpoint Blockade for Hepatocellular Carcinoma.\nAbstract: Immune checkpoint inhibitors are standard therapy for unresectable hepatocellular carcinoma (HCC), but rare immune-related adverse events may be life-threatening. We describe an 80-year-old man with unresectable HCC who received dual durvalumab and tremelimumab on a non-STRIDE schedule. Within four weeks, he developed ptosis, diplopia, and bulbar weakness that rapidly progressed to neuromuscular respiratory failure. Laboratory evaluation revealed markedly elevated creatine kinase, troponin, and aldolase levels, along with a strongly positive acetylcholine receptor antibody. Despite treatment with high-dose corticosteroids, intravenous immunoglobulin, and plasma exchange, neurologic recovery was limited, and he experienced recurrent respiratory decline. After confirming decision-making capacity, he chose to discontinue life-prolonging therapy and transitioned to hospice. This case highlights the fulminant potential of myasthenia-myositis overlap after programmed death-ligand 1 (PD-L1) plus cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) blockade, underscores the importance of early biomarker surveillance and rapid escalation to immunomodulatory therapy, and illustrates the need for early goals-of-care discussions in patients facing severe immune-related toxicities.\n\nID: 41126943\nTitle: Coexistence of Acute Demyelinating Polyneuropathy and LRP4-Positive Myasthenia Gravis.\nAbstract: Guillain-Barr\u00e9 syndrome (GBS) and myasthenia gravis (MG) are rare autoimmune disorders that may share overlapping features such as ophthalmoparesis, limb weakness, and bulbar symptoms, complicating the differential diagnosis. Coexistence of GBS and MG or chronic inflammatory demyelinating polyneuropathy and MG, particularly the low-density lipoprotein receptor-related protein 4 (LRP4) antibody-positive subtypes, is extremely rare. We present such a case to highlight diagnostic challenges. A 46-year-old man presented with distal weakness, sensory loss, facial diplegia, and dyspnea. Nerve conduction studies revealed demyelinating features, and cerebrospinal fluid analysis showed albuminocytologic dissociation. An acute demyelinating polyneuropathy, most likely GBS, was suspected, and clinical improvement was observed following plasmapheresis. Three weeks later, new symptoms including dysarthria and worsening bulbar weakness emerged. Repetitive nerve stimulation showed a decremental response. LRP4 antibodies were positive, confirming MG. The patient improved with intravenous immunoglobulin, corticosteroids, pyridostigmine, and azathioprine. This case underscores the rare coexistence of acute demyelinating polyneuropathy and LRP4-positive MG. In acute demyelinating polyneuropathy patients with relapsing or worsening symptoms, coexisting MG should be considered. Comprehensive electrophysiological evaluation and antibody testing, including LRP4, are essential for the accurate diagnosis of both conditions.\n\nID: 41103821\nTitle: A Hospitalist's Challenge: Systemic Botulism Following a Cosmetic Injection Requiring Antitoxin Therapy and Percutaneous Endoscopic Gastrostomy (PEG).\nAbstract: Botulinum toxin type A (BoNT-A) is widely used in cosmetic practice and generally considered safe, with adverse effects usually limited to transient local reactions. Rarely, systemic spread or counterfeit formulations can cause iatrogenic botulism, presenting with bulbar weakness and generalized neuromuscular dysfunction. We report the case of a 53-year-old woman who developed progressive dysphagia, bilateral ptosis, bifacial weakness, and proximal muscle weakness following cosmetic BoNT-A injections to the face and masseter muscles. Imaging and endoscopic evaluations were unremarkable, and myasthenia gravis (MG) was excluded. Despite initial\u00a0partial improvement on pyridostigmine, her bulbar dysfunction worsened, necessitating administration of botulinum antitoxin and eventual percutaneous endoscopic gastrostomy (PEG) placement for nutritional support. Over subsequent weeks, she demonstrated gradual recovery, though mild ptosis persisted at discharge. This case underscores the potential for systemic botulism after cosmetic BoNT-A, particularly in the setting of unregulated or counterfeit products. Physicians must maintain a high index of suspicion in patients with recent cosmetic injections presenting with cranial or bulbar symptoms, as timely recognition and antitoxin therapy are essential to optimize outcomes and reduce morbidity.\n=======================================================\n\n### [CUSTOM DATAPOINTS]\nCRITICAL EXTRACTION DIRECTIVE: You MUST extract the following custom datapoints as root-level key/value pairs inside your final JSON block:\n- \"suggested_experiments\": generate 1-3 suggested experiments\n- \"suggested_studies\": generate 1-3 suggested studies\n- \"swansons_literature_based_discovery_candidates\": You are an advanced Literature-Based Discovery (LBD) system executing Swanson\u2019s complementary-but-disjoint (A-B-C) model.

It is characterized by gradual disease progression with comparison to adult-onset ALS and is often linked to genetic mutations. A 16-years-old female presented with long history of generalized weakness since age of 10 years, followed by bilateral sensorineural hearing loss, bulbar symptoms, and limb spasticity. Neurological examination revealed upper motor neuron signs in upper limbs, lower motor neuron signs in lower limbs, and bulbar involvement. Nerve conduction test was normal however, MRI showed early degenerative changes, and diagnosed with J-ALS after careful evaluation. She was started on Riluzole. Despite ICU care and supportive interventions including PEG and tracheostomy, she succumbed to respiratory failure. Rarity, atypical presentation, and finical constraints can delay diagnosis of J-ALS. However, early diagnosis after careful evaluation of clinical symptoms, medical history, electrophysiological and imaging studies followed by prompt treatment with Riluzole and supportive interventions can help prolong survival and improve quality of life. J-ALS is a rare motor neuron disease which possess immense diagnostic challenges, can exhibit relentless progression over short period of time with time.\n  --- END ACTUAL ABSTRACT FOR 40901171 ---\n\n\n\u2705 PASSED (DO NOT CHANGE THESE):\n- \"Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up\" (Source: 42404894)\n- \"The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS\" (Source: 42040341)\n- \"T1 bright tongue as an indication of chronic denervation in bulbar involvement\" (Source: 41714394)\n- \"Additionally, contrast-enhanced magnetic resonance imaging is essential for differential diagnosis in bulbar palsy cases.\" (Source: 40701363)\n- \"The clinical presentation, coupled with the patient's report of the firework emitting a green flare, is most consistent with acute barium toxicity.\" (Source: 42078235)\n- \"These findings indicate that pyrimidine nucleos(t)ide therapy improves survival and functional outcomes in people with thymidine kinase 2 deficiency\" (Source: 42318512)\n- \"Atypical symptoms should not delay the diagnosis and treatment of GBS once other conditions have been adequately excluded.\" (Source: 41090254)\n- \"Continuous treatment was associated with lower risk of ALS complications, including hospitalization, respiratory failure, or death (HR, 0.36; 95% CI, 0.15-0.85; P\u2009=\u2009.02).\" (Source: 41837970)\n- \"Botulinum toxin significantly reduced sialorrhea and improved quality of life (Z\u2009=\u200910.98, p\u2009<\u20090.00001; RD\u2009=\u20090.82, 95% CI: 0.67\u20130.97).\" (Source: 41366746)\n\n\nINSTRUCTION: Study the actual abstracts provided.

Recent literature emphasizes a pivot toward objective, non-invasive assessment and targeted, rapid-acting immunomodulation. Advanced diagnostic pipelines now utilize quantitative markers to identify subclinical bulbar involvement, while therapeutic landscapes have expanded to include agents that provide rapid relief in crisis scenarios. These developments represent a departure from purely supportive management toward precision-based neurological intervention.\n\n### [DISCUSSION: NOVEL & OVERLOOKED]\n*   Efgartigimod and ravulizumab have transitioned into roles as effective bridging or rescue strategies for severe, refractory MG bulbar crisis.\n*   Objective sEMG protocols enable the detection of subclinical bulbar decline, providing a measurement-based framework that is resistant to cognitive-linguistic confounders.\n*   Smartphone-based deep learning (U-Net++ models) offers a scalable, low-barrier diagnostic interface for quantifying tongue motor dysfunction in ALS.\n*   Pyrimidine nucleoside replacement therapy has fundamentally altered the prognosis for infantile-onset TK2 deficiency, enabling milestone recovery previously deemed impossible.\n*   The prevalence of sialorrhea in ALS bulbar-onset cases is increasingly managed through botulinum toxin injection regardless of specific injection technique.\n*   The concept of \"dying back\" of UMN axons in ALS has been refined, with imaging indicating degeneration stops at the brainstem, sparing cortical motor neurons.\n*   The use of PSQI scores to assess sleep quality provides an independent prognostic indicator for bulbar-onset MG and short-term clinical outcomes.\n*   Barium toxicity represents a rare mimic of GBS-like bulbar paralysis, emphasizing the necessity of toxicological screening in unexplained acute paralysis.\n*   Dynamic chest MRI and ultrasound serve as critical objective surrogates for pulmonary function tests in patients where bulbar involvement precludes traditional spirometry.\n*   The presence of LRP4 antibodies characterizes a unique, rare subset of MG coexisting with demyelinating neuropathy, requiring specialized diagnostic panels.\n\n### [EVIDENCE, METHODOLOGY & CITATIONS]\n1.

Additional neurological abnormalities in the 15 with complicated HSP included cognitive impairment, pseudo-bulbar palsy, cerebellar dysfunction and polyneuropathy. 19 children presented with abnormal gait, recognised at a mean age of three years in the pure form and five years in the complicated form. These forms were distinguished at a mean age of 11 years. Early non-motor developmental delay or rapidly ascending paraparesis, with spread of spasticity to the arms and with involvement of bulbar structures, predicted development of the complicated form. The pure form was inherited in an autosomal dominant manner in five patients. The autosomal recessive form was commonly associated with additional neurological abnormalities and a more rapid rate of progression.",

Magnetic resonance imaging (MRI) revealed a Gd-DTPA enhanced lesion from the level of the medulla oblongata, involving the reticular formation, to that of the vertebral body C2. She became abruptly unable to breath following aggravation of bulbar palsy and tetraplegia and mechanical ventilation was immediately initiated. The next day, voluntary breathing re-appeared but automatic respiratory failure remained unchanged. The respirator was completely removed after one month, and then the breathing was almost normal. In MS patients who develop intractable hiccup as an early symptom, it is suggested that the causative lesion is in the medulla oblongata. In such cases, we must carefully observe the clinical course because expansion of the lesion may induce respiratory failure.",

As respiration was almost arrested, artificial respiration was started and continued for five days. Respiration was almost normal after 16 days from the onset of respiratory arrest. MRI showed bilateral, medullary lesions without upper cervical lesions. Pyramidal tracts, medial lemnisci, and paramedian reticular formations in medulla were damaged bilaterally. We supposed that the medullary lesions involved dual respiratory systems: a voluntary system and an automatic system, and caused acute respiratory arrest.",

A 42-year-old man was admitted to our hospital in April, 1991 with marked respiratory distress. He had been diagnosed as having CMT 14 years previously. On admission to our hospital, he revealed dyspnea with marked stridor during inspiration. Physical examination showed marked use of respiratory accessory muscles with thoracoabdominal paradox in the supine position. Neurologic examination revealed tonic pupils, mild bilateral weakness of facial muscles, deafness, mild bulbar palsy, severe wasting and weakness in both proximal and distal muscles of the arms and legs, areflexia, distal loss of all sensory modalities. Pes cavus and hammer toe were present. Movement of upper extremities was ataxic. No hypertrophic changes were noted in his peripheral nerves. Peripheral nerve conduction study showed undetectable both sensory and motor action potentials. Electromyography showed evidence of denervation, more marked in distal muscles. Auditory brain stem response was undetectable. Chest radiographic film showed a normal-sized heart with marked elevation of both hemidiaphragm. Laryngofiberscopy confirmed the presence of bilateral vocal cord paralysis without tumor formation, inflammation or anomaly. The vocal cords lay near the midline and did not show any movement during respiration. Moderate cerebellopontine atrophy was confirmed on MRI scan. A sural nerve section showed severe decrease of myelinated fibers, and onion bulbs. Diagnosis of HMSN type 1 was made by clinical, electrodiagnostic, and sural nerve sections study.(ABSTRACT TRUNCATED AT 250 WORDS)",

He was well until his 48 years of the age (December 1994) when he noted a difficulty in speaking in loud voice. In February, 1995, he noted regurgitation of foods to his nose and difficulty in his speech. He was admitted to our service in May 29, 1995. On admission, he was alert and oriented to all spheres and he was not demented. His higher cerebral functions were normal. In cranial nerves, he showed dysarthria and dysphagia; muscle atrophies were seen in the tongue, the bilateral sternocleidomastoid, supraspinatus, and infraspinatus muscles. Fasciculations were seen in these muscles. He showed no muscle weakness in his limbs except for the upper limb girdle muscles, no ataxia, no reflex abnormalities, nor sensory changes. EMG showed neurogenic changes in the affected muscles. MRI of the brain and the spinal cord was entirely normal. He was discharged for out patient follow-up, however, in October of 1995, he noted difficulty in swallowing solid foods. Gastrostomy was placed and he was discharged to his home. In February 11th of 1996, he was found unresponsive and brought into the ER of our hospital. On admission, he was comatose without spontaneous respiration. BP could not be obtained. He was immediately intubated and artificial ventilation was started. On the following morning, he became alert and he was not demented. He continued to show marked dysarthria and dysphagia; again no weakness was noted in the distal parts of the upper and lower extremities. Laboratory examination showed increase in serum CK to 2,173 IU/L and amylase to 2,032 IU/L. He was extubated on February 15th, however, his spontaneous respiration was not suffice to maintain his blood gas. According to his will, he was not placed on respirator and he died on February 24th, 1996. The patient was discussed in a neurological CPC and the chief discussant arrived at the conclusion that the patient had ALS. Although no upper neuron signs were observed clinically, it is not uncommon to see degeneration in the corticospinal tract in post-mortem examination. The question was what might have been the cause of increase in CK and amylase. Many participants thought that they were secondary to multiple organ failure due to prolonged hypoxic state at his last admission; other possibilities raised included acute myocardial infarction and acute bowel necrosis. Post-mortem examination revealed muscle atrophy in the facial, lingual, cervical, intercostal, and the upper limb girdle areas. The lungs were unremarkable except for old organized pneumonic foci in the right middle and lower lobes. Marked to moderate congestion was seen in many internal organs, however, no other gross abnormality was found. It was thought that respiratory palsy itself was the direct cause of his agonal event. In the spinal cord, the anterior horns showed various degree of neuronal loss and gliosis. No clear evidence of pyramidal tract degeneration was seen at the light microscope level. Lower brain stem motor neurons were markedly reduced. But no Bunina body was found. The substantia nigra showed moderate degree of neuronal loss and extraneuronal neuromelanins. The locus coeruleus showed similar but milder changes. The degree of nigral degeneration appeared to be well beyond those which could be seen in usual ALS patients. The question was whether or not this patient might have been in an early stage of the extended form of ALS.",

These patients showed neither upper motor neuron signs nor upper motor neuron system involvement including the corticospinal tract in postmortem tissues after conventional stainings. Specimens from 12 age-matched normal individuals served as controls. All patients showed loss of brainstem motor neurons and anterior horn cells. Betz cells in LMND patients were significantly reduced in number as compared to controls (P<0.01). However, there was no significant difference in the density of phosphorylated neurofilament (PNF) (200 kDa)-positive Betz cells between LMND patients and controls. The pyramidal cells of layer III were immunostained for PNF in four of six LMND patients, but there was no significant difference in the density of PNF-positive pyramidal cells between LMND patients and controls. The number of astrocytes immunostained for glial fibrillary acidic protein increased in layer III and at the transition between white matter and motor cortex in three out of six patients and one of 12 controls. Ultrastructural examination revealed that the Betz cells of five of six LMND patients had Bunina bodies, Lewy body-like inclusions or skein-like inclusions, all of which are characteristic of amyotrophic lateral sclerosis (ALS). These findings suggest that most patients with clinically and pathologically-diagnosed LMND should be classified into the category of ALS.",

Some patients exhibit only systemic disease (type I), but others have additional neurological signs which may lead to rapid neurodegeneration in infancy (type II) or take a more intermediate course (type III). Types II and III are collectively known as neuronopathic Gaucher disease (NGD). Systemic disease can now be treated by enzyme replacement therapy (ERT), but its efficacy in NGD is limited. Two infants who presented with bulbar palsy and failure to thrive were enzymatically diagnosed at 8 months with NGD. They were started on high-dose ERT (120 IU/kg every 2 weeks). Both underwent serial oculomotor assessment and an audiological battery, including visual reinforcement audiometry, otoacoustic emissions, and the auditory brain stem response (ABR). Biochemical markers showed an incomplete systemic response to ERT, but neurological deterioration was relentless, leading to death at 16 and 25 months. Oculomotor testing revealed a complete absence of saccadic eye movements and progressive bilateral sixth nerve palsy in one. Audiological assessment revealed progressive deterioration of ABRs, but with normal peripheral hearing and otoacoustic emissions. Both infants showed neurological deterioration in spite of high-dose ERT. The audiological findings suggested a loss of inner hair cell pathway function with preserved outer hair function, similar to what is seen in auditory neuropathy. The unusual pattern of audiological and oculomotor abnormalities is consistent with an excitotoxic mechanism predisposing nerve cells to glucocerebroside toxicity. Such excitotoxic damage may be amenable to direct therapeutic intervention.",

The rima glottis in the larynx is an important site where aspirated food or material becomes lodged, thereby causing laryngeal obstruction (choking). Because the lungs still contain air, intentional compression thrusts to the abdomen (Heimlich manoeuvre) will theoretically expel air from the lungs and dislodge the entrapped food or other material. The manoeuvre can also be used to expel aspirated water from the airways in cases of near drowning. The manoeuvre has been found to be successful as an emergency adjunct measure in removing food blocking the airway.",

Diagnoses of ALS were made because of continuous aspiration caused by bulbar palsy in patient 1, and, in patient 2, because of the progressive muscle atrophy that occurred during unsuccessful attempts to wean the patient from ventilatory support. Physicians should be aware of the possibility of ALS in cases of acute respiratory failure, CO2 narcosis, continuous aspiration, and difficulty of weaning from mechanical ventilation.",

We analyzed the pattern of progression of clinical symptoms and respiratory dysfunction in 26 sporadic ALS patients (19 men, 7 women; mean age 73.2 +/- 6.0 years) with onset at age 65 years or older (E-ALS). We compared the results with those of 28 ALS patients (20 men, 8 women; 53.7 +/- 7.6 years) with younger onset ALS (Y-ALS). Among E-ALS patients, the bulbar palsy type (BP) was the most common (11 patients, 42%) followed by the respiratory failure type (RF) (7 patients, 27%). In contrast, upper extremity type (UE) was the most common (14 patients, 50%) in Y-ALS patients. Mean vital capacity percentage (%VC) at the initial examination was 71.1 +/- 20.4% (vital capacity (VC): 2.12 +/- 0.85 L) in all E-ALS patients, 64.5 +/- 14.5% in BP, 58.1 +/- 5.1% in RF, 94.4 +/- 11.1% in lower extremity type (LE), and 73.9 +/- 30.2% in UE. In all Y-ALS patients, %VC was 90.1 +/- 14.0% (2.94 +/- 0.57 L). The initial % VC value in E-ALS was significantly lower than that in Y-ALS (p < 0.01). VC was lower in RF and BP among E-ALS patients. It was also lower in BP E-ALS patients than in BP Y-ALS patients. Mean period from initial symptom until first examination was significantly shorter in RF in both groups, followed by BP. Twenty-two patients with E-ALS and 26 with Y-ALS died from respiratory failure. Four patients with E-ALS and 2 with Y-ALS required a mechanical ventilator. The mean period until death or ventilation support was 20.9 +/- 10.4 months in E-ALS, and 38.8 +/- 21.1 months in Y-ALS. Significantly shorter survival was observed in E-ALS than Y-ALS (p<0.01). In E-ALS patients, the mean period until death or ventilation support was 21.4 +/- 9.1 months with BP, 10.3 +/- 7.6 months with RF, 29.8 +/- 4.0 months with LE, and 29.3 +/- 5.4 months with UE. This period was significantly shorter in RF patients in both groups, followed by BP patients (p< 0.05, 0.01). Time until death or ventilation support was significantly shorter in BP and UE patients with E-ALS than in those with Y-ALS (p< 0.05). In regard to the progression of respiratory function deterioration, early % VC was lower in E-ALS than in Y-ALS patients, and the period until VC fell below 1 L was shorter. The period until death was particularly short in elderly BP and RF patients, suggesting the possibility that the duration until death from respiratory failure is shorter in E-ALS, because of a decrease in respiratory reverse capacity that accompanies age.",

Therefore, we conducted a retrospective follow-up study to review airway and neurological sequelae development in patients with severe EV71 infection. We also studied the incidence and risk factors for tracheotomy and gastrostomy requirement. We investigated 202 EV71-infected children according to their disease stage. Seventy-two of them were diagnosed to have EV71 encephalitis, which was characterized by myoclonus, ataxia, nystagmus, oculomotor palsy and bulbar palsy or combinations of these conditions. All the 72 patients required endotracheal intubation due to respiratory failure or ventilator dependence; among these, 14 underwent tracheostomy and 10 underwent gastrostomy. All patients were followed-up for at least 3 years after discharge. Predictors of tracheostomy and gastrostomy requirement were age <2 years, body weight <10th percentile, pulmonary hemorrhage or edema, meningeal symptoms and magnetic resonance imaging (MRI) findings of upper spinal cord and brainstem. We determined outcome based on persistent tracheostomy or gastrostomy requirement and whether patients developed positive neurological sequelae. Significant tracheostomy and gastrostomy predictors were age <2 years, pulmonary edema or hemorrhage, hypotension, hemiparesis and positive MRI findings. Statistical analysis revealed pulmonary edema and hypotension as index predictors of tracheostomy requirement and pulmonary edema as the significant risk factor for gastrostomy. Long-term neuropsychological impact was observed on children who present the signs of the pulmonary edema or hypotension in the early onset of the EV71 infection. EV71-infected patients who develop neurological pulmonary edema or hypotension should be hemodynamically stabilized and undergo early tracheostomy to prevent further complications. This may improve the decannulation success rate after the brainstem function recovers.",

Contributing factors are hypersecretion of saliva induced by cholinergic drugs and poor dental status. Non-invasive ventilation is often severely impaired in these patients. Treatment should be initiated with a thorough evaluation of the medication and of the oral status by an otorhinolaryngologist. As drooling is commonly caused by poor oral or pharyngeal neuromuscular control, swallowing therapy should be initiated by a speech therapist. Further treatment options are anticholinergic medications, botulinum toxin injections into the salivary gland, radiation and and surgical procedures. Whereas systemic anticholinergic medications lead often to side effects, the (ultrasound-guided) injection of botulinum toxin into the parotid and submandibular gland is a safe and effective method for controlling drooling for at least 2 months.",

The day after endoscopic resection, she became drowsy and dysphasic. Two days later, left hemiparesis and gait difficulty developed. The next day, hemiparesis progressed bilaterally and dyspnea developed due to upper airway stenosis. The most prominent signs were those of bulbar palsy. Blood analysis revealed mild inflammatory responses and hyponatremia. T2-weighted magnetic resonance imaging showed high-intensity lesions in the swollen medulla and cervical spinal cord. Those areas and the meninges of the posterior fossa were enhanced by gadolinium. Steroid pulse therapy was administered, resulting in rapid recovery of bulbar and paretic symptoms with decreased enhanced area. At this point, concentration of cerebrospinal fluid interleukin (IL)-10 was markedly elevated at 146 pg/ml (normal,< 5 pg/ml), suggesting malignant lymphoma. Cytology of the cerebrospinal fluid was repeatedly examined, eventually revealing atypical lymphocytes with hyperlobulated nuclei and clear nucleoli. Lymphocytes stained with anti-CD20 antibody. These findings strongly suggested a diagnosis of primary intraocular and central nervous system lymphoma.

Identification of modifiable risk factors may help in reducing the morbidity and mortality. To study the prognostic factors in a selected cohort of mechanically ventilated GBS patients. Case records of GBS patients requiring mechanical ventilation admitted between 1997 and 2007 were analyzed. All patients satisfied the National Institute of Neurological and Communicative Disorders and Stroke (NINCDS) criteria for GBS. Primary outcome parameters included mortality and GBS disability (Hughes) scale score at discharge. During the study period, 173 (118 men and 55 women; mean age of 33.5 \u00b1 21 years) GBS patients were mechanically ventilated. A history of antecedent events was present in 83 (48%) patients. In addition to motor weakness, In all facial palsy was present in 106 (61%), bulbar palsy in 91 (53%), sensory involvement in 74 (43%), and symptomatic autonomic dysfunction in 27 (16%).

The family comprised nine patients (six men and three women). We reviewed their clinical records and performed mutation analysis of the copper/zinc superoxide dismutase (SOD1) gene in some of these patients. The patients either had a rapid (n=7) or an extremely long (n=2) clinical course. The mean age at onset was 39.0\u00b113.7 years (range 20-68 years). The initial symptoms were bulbar palsy (n=2), upper (n=4) or lower (n=2) limb muscle weakness, or leg cramps (n=1). The total disease duration varied widely, ranging from one year to >69 years.

Mutations in SLC52A3 (formerly C20orf54), coding for riboflavin transporter 2 (hRFT2), have been identified as the molecular genetic correlate in several individuals with BVVLS. Exome sequencing of just one single case revealed that compound heterozygosity for two pathogenic mutations in the SLC52A2 gene coding for riboflavin transporter 3 (hRFT3), another member of the riboflavin transporter family, is also associated with BVVLS. Overexpression studies confirmed that the gene products of both mutant alleles have reduced riboflavin transport activities. While mutations in SLC52A3 cause decreased plasma riboflavin levels, concordant with a role of SLC52A3 in riboflavin uptake from food, the SLC52A2-mutant individual had normal plasma riboflavin concentrations, a finding in line with a postulated function of SLC52A2 in riboflavin uptake from blood into target cells. Our results contribute to the understanding of human riboflavin metabolism and underscore its role in the pathogenesis of BVVLS, thereby providing a rational basis for a high-dose riboflavin treatment.",

At the age of 70 years, the patient was admitted to our hospital because of progressive weakness and dysesthesia in the right upper limb. In the early stages of the illness, he was diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), and transient improvement was achieved with intravenous immunoglobulin. However, the symptoms progressively worsened and became refractory. Gene analysis revealed PMP22 gene duplication, which confirmed CMT1A. On sural nerve biopsy, severe demyelinating neuropathy and abundant onion-bulb formations with endoneurial infiltration of inflammatory cells were observed. Thereafter, pseudo-bulbar palsy and respiratory muscle weakness developed insidiously and progressed rapidly along with muscle weakness in the limbs and trunk. The patient died about four years after the onset of this disease. Postmortem examination showed moderate neuronal cell loss, Bunina bodies, and TDP-43-positive inclusions in the anterior horn cells. The spinal cord revealed axonal loss and extensive macrophage permeation in the corticospinal tracts. On the basis of these findings, the final neuropathological diagnosis was ALS.

However, advancement in motor neuron replacement therapy has been significantly constrained by the difficulties in large-scale production at a cost-effective manner.

These existing methods are seriously challenged by extensive time requirements and poor yields. An innovative approach that overcomes prior hurdles and enhances the rate of successful motor neuron transplantation in patients is of critical demand. Iron, a trace element, is indispensable for the normal development and function of the central nervous system. Whether ferric ions promote neuronal differentiation and subsequently promote motor neuron lineage has never been considered. Here, we demonstrate that elevated iron concentration can drastically accelerate the differentiation of human embryonic stem cells (hESCs) toward motor neuron lineage potentially via a transferrin mediated pathway. HB9 expression in 500\u2009nM iron-treated hESCs is approximately twofold higher than the control. Moreover, iron treatment generated more matured and functional motor neuron-like cells that are \u223c1.5 times more sensitive to depolarization when compared to the control. Our methodology renders an expedited approach to harvest motor neuron-like cells for disease, traumatic injury regeneration, and drug screening.",

Here, we tested this association in 107 sporadic amyotrophic lateral sclerosis patients and 100 healthy controls from the Chinese Han population. We screened the mutation-susceptible regions of MAPT - the 3' and 5' untranslated regions as well as introns 9, 10, 11, and 12 - by direct sequencing, and identified 33 genetic variations. Two of these, 105788 A > G in intron 9 and 123972 T > A in intron 11, were not present in the control group. The age of onset in patients with the 105788 A > G and/or the 123972 T > A variant was younger than that in patients without either genetic variation. Moreover, the pa-tients with a genetic variation were more prone to bulbar palsy and breathing difficulties than those with the wild-type genotype. This led to a shorter survival period in patients with a MAPT genetic variant. Our study suggests that the MAPT gene is a potential risk gene for sporadic amyotrophic lateral sclerosis in the Chinese Han population.",

We submit a case of a 46-year-old male with a history of alcohol abuse, diabetes, hypertension, and hepatitis C who presented with fever, nausea, shortness of breath, and dysphagia. The patient rapidly developed hypercapnic respiratory failure and was found to have WNV meningoencephalitis without obvious neuromuscular weakness. His hospital course was significant for repeated failures of extubation secondary to persistent bulbar weakness eventually requiring tracheotomy. This is a unique case of WNV meningoencephalitis with bulbar palsy without other neuromuscular manifestations resulting in recurrent hypercapnic respiratory failure.",

CSM may carry the potential for serious neurovascular complications, primarily due to vertebral artery dissection (VAD) and subsequent vertebrobasilar stroke. Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy.A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour. Gradually, although the patient remained conscious, he could not speak but could communicate with the surrounding by blinking or moving his eyes, and turned to complete quadriplegia, complete facial and bulbar palsy, dyspnea at 4\u200ahours after admission. He was diagnosed with LIS. Then, the patient was received cervical and brain computed tomography angiography that showed bilateral VAD. Aortocranial digital subtraction angiography showed vertebrobasilar thrombosis, blocking left vertebral artery, and stenosis of right vertebral artery. The patient was treated by using emergency arterial embolectomy and followed by antiplatelet therapy and supportive therapy in the intensive care unit and a general ward. Twenty-seven days later, the patient's physical function gradually improved and discharged but still left neurological deficit with muscle strength grade 3/5 and hyperreflexia of limbs.Our findings suggested that CSM might have potential severe side-effect like LIS due to bilaterial VAD, and arterial embolectomy is an important treatment choice. The practitioner must be aware of this complication and should give the patients informed consent to CSM, although not all stroke cases temporally related to SCM have pre-existing craniocervical artery dissection.",

A 62-year-old man had bulbar palsy with progressive weakness in the extremities. Neurological examination revealed evident upper motor neuron signs and lower motor neuron involvement corroborated by needle electromyography. The patient was diagnosed as having probable ALS according to the revised El Escorial diagnostic criteria and was eventually diagnosed with familial ALS. At 65\u2009years of age, respiratory failure became critical, and artificial ventilation was initiated. At 70\u2009years of age, the patient died from a urinary tract infection. Histopathological investigation showed Bunina bodies in the remaining motor neurons and anterolateral funicular myelin pallor in the spinal cord. TDP-43-positive cytoplasmic inclusions were quite rare in the spinal cord motor neurons, being predominantly present in the glial cells (especially astrocytes) of the spinal cord anterior horn.

Motor neurons could be divided into two groups, which are upper groups in the motor cortex and lower groups in the brain stem and spinal cord. Loss of lower motor neurons leads to muscle weakness, wasting and cramps. Loss of upper motor neurons leads to brisk reflexes and functional limits. There are several types of motor neuron disease: amyotrophic lateral sclerosis (ALS), progressive bulbar palsy (PBP), progressive muscular atrophy (PMA), primary lateral sclerosis (PLS). Now, the studies of autophagy in MND focus on the type of ALS, so this chapter will summarize the alteration of autophagy in motor neurons, and how that knowledge contributes to our understanding of the pathogenesis of ALS.",

Serum complements (C3, C4 and soluble C5b-9) and complement regulators (vitronectin, clusterin and properdin) were extensively analysed by enzyme-linked immunosorbent assay and their associations with clinical profiles of MG were examined. Serum C3, C4 and clusterin levels were not significantly different between patients with MG and controls. The patients with MG had higher soluble C5b-9 (P\u00a0=\u00a00.09) and vitronectin (P\u00a0=\u00a00.001) levels than the controls; moreover, vitronectin levels decreased after treatment (P\u00a0=\u00a00.09).

Here, we present a 2-year-old boy whose initial presentation was severe macrocytic anemia necessitating multiple blood transfusions and intermittent neutropenia; he subsequently developed ataxia and dysarthria. Trio-exome sequencing detected compound heterozygous variants in SLC52A2 that were classified as pathogenic and a variant of uncertain significance. Bone marrow evaluation demonstrated megaloblastic changes. Notably, his anemia and neutropenia resolved after treatment with oral riboflavin, thus expanding the clinical phenotype of this disorder. We reiterate the importance of starting riboflavin supplementation in a young child who presents with macrocytic anemia and neurological features while awaiting biochemical and genetic work up. We detected multiple biochemical abnormalities with the help of untargeted metabolomics analysis associated with abnormal flavin adenine nucleotide function which normalized after treatment, emphasizing the reversible pathomechanisms involved in this disorder. The utility of untargeted metabolomics analysis to monitor the effects of riboflavin supplementation in RTD has not been previously reported.",

However, the aetiology and pathogenesis of ALS have not been elucidated to date. In this study, a competitive endogenous RNA (ceRNA) network was constructed by analyzing the expression profiles of messenger RNAs (mRNAs) and long noncoding RNAs (lncRNAs) that were matched by 7 ALS samples and 4 control samples, and then a protein-protein interaction (PPI) network was constructed to identify the genes related to ALS. Gene Ontology (GO) was used to study the potential functions of differentially expressed mRNAs (DEmRNAs) in the ceRNA network. For the ALS and control groups, 247177 potential lncRNA-mRNA ceRNA relationship pairs were screened. Analysis of significant relationship pairs demonstrated that the PPI modules formed by the MALAT1-regulated SYNRG, ITSN2, PICALM, AP3B1, and AAK1 genes may play important roles in the pathogenesis of ALS, and these results may help to characterize the pathogenesis of ALS.",

This study aimed to determine the clinical predictors and electrodiagnostic (EDx) characteristics in patients with Guillain-Barr\u00e9 syndrome (GBS) with respiratory failure. The retrospective study included 29 confirmed GBS cases with respiratory failure and age- (\u00b15 years) and sex-matched controls (1:1). The dependent t-test and McNemar-Bowker test were used to analyse the continuous and categorical data, respectively. In addition, a multiple logistic regression analysis was used to analyse the predictive factors for respiratory failure. Among both cases and controls, the majority were male (72.4%), and the average age was 50.9 years. The data showed that patients with respiratory failure had higher GBS disability scores, lower motor power (\u22643) of the hip flexors and ankle dorsiflexors, and experienced facial and bulbar palsy. In the multivariate analysis, the significant predictive factors were bulbar palsy (AOR 10.4 [95% CI [2.6-41.4]) and motor power of hip flexors \u2264 3 (AOR 31.4 [95% CI [3.1-314.5]). Patients with respiratory failure had lower compound muscle action potential amplitude of the ulnar and tibial nerves. The median, ulnar, and tibial nerve conduction studies were more likely to reflect inexcitability. The GBS subtypes in GBS patients with and without respiratory failure were not significantly different. Bulbar palsy and motor power of the hip flexors \u2264 3 were significant predictors for respiratory failure. The GBS subtypes in patients with and without respiratory failure were not significantly different.",

Her initial symptom was gait disturbance, and she subsequently developed limb weakness and Parkinsonism without response to levodopa. Her motor symptoms progressed to bulbar palsy, and she died of respiratory failure. Postmortem examination revealed characteristic findings of amyotrophic lateral sclerosis (ALS), including motor neuronal loss with astrogliosis, corticospinal tract degeneration, and TAR DNA-binding protein of 43\u2009kDa abnormalities, including nuclear loss and skein-like inclusions. In contrast, severe tau pathological changes were seen in the frontotemporal lobes and pallido-nigral system. Tau pathologies affected not only neuronal components, such as neurofibrillary tangles and neuropil threads, but also glial cells (astrocytes and oligodendrocytes). Some glial tau pathologies exhibited peculiar round accumulations, reminiscent of globular glial inclusions (GGIs) in globular glial tauopathy. This unique autopsy case demonstrates that ALS with TDP-43 could be comorbid with globular glial tau inclusions and indicates that common pathological mechanisms exist among ALS and GGI formation.",

CPM is a rare neurological disorder that generally develops after rapid correction of hyponatremia in individuals having underlying conditions, such as malnutrition, alcoholism, and severe burns. It can cause severe long-term disabilities. However, there is currently no pharmacotherapy capable of promoting remyelination, a process crucial for recovery from CPM. We present the case of a patient with alcoholism and malnutrition-related CPM, which developed following rapid correction of hyponatremia but then improved remarkably with supportive physical therapy. CASE REPORT A 44-year-old alcoholic and malnourished man was admitted to an emergency hospital for disorientation due to overdrinking, but later developed bulbar palsy after hyponatremia was unexpectedly, but rapidly, corrected. Axial scans of the diffusion-weighted brain MRI revealed a characteristic lesion known as a piglet sign in the central pons. Based on his underlying conditions, present episode of sodium correction, and MRI finding, the patient was diagnosed as having CPM, which progressively worsened, resulting in locked-in syndrome after 12 days. The patient was then transferred to a long-term care unit and received simple motion exercise daily, but no specific medication. His symptoms gradually improved, achieving discontinuation of tube feeding on day 21, independent walking on day 110, and discharge after 6 months. CONCLUSIONS This report highlights the importance of physical therapy, the potential of which is often underestimated despite its broad benefits for human health, as a readily applicable intervention for patients with CPM. Further understanding of mechanisms underlying exercise-induced myelination should contribute to establishing novel therapies for a wide spectrum of brain disorders.",

Data from the first 1500 patients included in the prospective International GBS Outcome Study (IGOS) were used. Patients were included across five continents. Patients <6 years and patients from Bangladesh were excluded. Univariable logistic and multivariable Cox regression were used to determine which prespecified clinical and diagnostic characteristics were associated with MV and to predict the risk of MV at multiple time points during disease course. 1133 (76%) patients met the study criteria. Independent predictors of MV were a shorter time from onset of weakness until admission, the presence of bulbar palsy and weakness of neck flexion and hip flexion. The modified EGRIS (mEGRIS) was based on these factors and accurately predicts the risk of MV with an area under the curve (AUC) of 0.84 (0.80-0.88). We internally validated the model within the full IGOS cohort and within separate regional subgroups, which showed AUC values of 0.83 (0.81-0.88) and 0.85 (0.72-0.98), respectively. The mEGRIS is a simple and accurate tool for predicting the risk of MV in GBS. Compared with the original model, the mEGRIS requires less information for predictions with equal accuracy, can be used to predict MV at multiple time points and is also applicable in less severely affected patients and GBS variants. Model performance was consistent across different regions.",

We retrospectively compared the clinical characteristics at the initial examination of patients with onset of ALS at age 74\u00a0years or younger (early onset) and those aged 75\u00a0years or older at onset (late-onset) at a single regional ALS diagnostic center in Japan. The phenotype of late-onset ALS differed between males and females, with late-onset females having more bulbar-onset ALS and significantly lower body mass index, late-onset males having more frequent bulbar and respiratory symptoms at the initial examination, and significantly lower forced vital capacity at the initial examination in both groups compared to early onset patients. For late-onset patients, maintenance of skeletal muscle mass by early intervention for bulbar and respiratory symptoms may be useful for prolonging survival; however, a prospective analysis is warranted.",

However, most research has focused on its later stages rather than its earlier stages, including the prognosis of patients with this condition, or factors that act as early predictors of risk. Therefore, our study aimed to identify early predictors of respiratory muscle paralysis in patients with GBS and determine the short-term prognosis of such patients. We recruited 455 GBS patients (age \u2265 18) who had been hospitalized in the First Affiliated Hospital of Harbin Medical University between 2016 and 2021, retrospectively. We recorded clinical and laboratory data and used linear and logistic regression analysis to investigate the relationship between early clinical, examination results, and subsequent respiratory muscle paralysis. Among the 455 patients, 129 were assigned to a respiratory muscle paralysis group and 326 were assigned to a non-respiratory muscle paralysis group. Compared with the non-affected group, the time from onset to admission was shorter (p = 0.0003), and the Medical Research Council (MRC) score at admission and discharge was smaller in the affected group (p < 0.0001). Compared with the non-affected group, the affected group had higher Hughes and Erasmus GBS Respiratory Insufficiency Score (EGRIS) scores at admission and longer hospital stays (p < 0.0001). Patients in the affected group were more likely to have bulbar palsy and lung infections (p < 0.0001). To conclude, bulbar palsy, a higher EGRIS score and Hughes score at admission, a lower MRC score, and a shorter time between onset and admission, are all predictive risk factors for respiratory muscle paralysis in patients with GBS. An increase in any of these factors increases the risk of muscle paralysis. Patients with respiratory muscle paralysis have a poorer short-term prognosis than those without respiratory muscle paralysis. Therefore, we should attempt to identify patients with one or more of these characteristics in the early stages of admission, provide ventilation management, and administer IMV treatment if necessary.",

Intermittent oro-esophageal tube feeding (IOE) can help alleviate these concerns. This study explored the clinical effect of IOE versus NG on nutritional status, swallowing function, stroke-associated pneumonia, and depression in patients with bulbar palsy after ischemic stroke. This randomized controlled study included 148 patients with bulbar palsy after ischemic stroke who underwent routine treatment and swallowing rehabilitation training in the Department of Rehabilitation Medicine between July 2017 and July 2019 in China. The participants were randomly divided into the IOE group (n=74) and NG group (n=74) with IOE and NG as nutritional supports, respectively. The primary outcome was nutritional status including (1) body mass index (kg/m2), (2) serum ALB (albumin, g/L), and (3) PA (prealbumin, mg/L). The secondary outcomes were (1) swallowing function including (i) Functional Oral Intake Scale (FOIS) and (ii) Penetration-Aspiration Scale, (2) pneumonia, (3) depression, and (4) adverse events. Statistical analyses for continuous outcomes were performed using t test, Mann-Whitney U test and Wilcoxon signed-rank test and categorical variables using \u03c72 test. SPSS 21.0 was used for all analysis. There were no significant baseline differences between the 2 groups. After the treatment, the IOE group demonstrated significantly better results compared with the NG group in ALB ([32.71\u00b10.94] versus [32.28\u00b10.81] g/L; P=0.003), PA ([278.15\u00b113.81] versus [270.31\u00b115.08] mg/L; P=0.001], body mass index ([19.77\u00b11.03] versus [19.41\u00b10.98] kg/m2; P=0.002], FOIS (P<0.001), Penetration-Aspiration Scale (P<0.001), stroke-associated pneumonia ([1, 4.05%] versus [26, 35.14%]; P<0.001), depression ([1, 1.35%] versus [44, 59.46%]; P<0.001) and overall less adverse events (reflux, fever, discomfort in the throat; P<0.001).

Impairment of these neural networks causes progressive muscle atrophy and weakness that spreads throughout the body, resulting in life-threatening bulbar palsy and respiratory muscle paralysis. However, no therapeutic strategy has yet been established to halt ALS progression. Although evidence for clinical practice in ALS remains insufficient, novel research findings have steadily accumulated in recent years. To provide updated evidence-based or expert consensus recommendations for the diagnosis and management of ALS, the ALS Clinical Practice Guideline Development Committee, approved by the Japanese Society of Neurology, revised and published the Japanese clinical practice guidelines for the management of ALS in 2023. In this guideline, disease-modifying therapies that have accumulated evidence from randomized controlled trials were defined as \"Clinical Questions,\" in which the level of evidence was determined by systematic reviews. In contrast, \"Questions and Answers\" were defined as issues of clinically important but insufficient evidence, according to reports of a small number of cases, observational studies, and expert opinions. Based on a literature search performed in February 2022, recommendations were reached by consensus, determined by an independent panel, reviewed by external reviewers, and submitted for public comments by Japanese Society of Neurology members before publication. In this article, we summarize the revised Japanese guidelines for ALS, highlighting the regional and cultural diversity of care processes and decision-making. The guidelines cover a broad range of essential topics such as etiology, diagnostic criteria, disease monitoring and treatments, management of symptoms, respiration, rehabilitation, nutrition, metabolism, patient instructions, and various types of care support. We believe that this summary will help improve the daily clinical practice for individuals living with ALS and their caregivers.",

To measure tongue atrophy, an operator independent automatic segmentation of the tongue is crucial. The aim of this study was to apply convolutional neural network (CNN) to MRI data in order to determine the volume of the tongue. A single triplanar CNN of U-Net architecture trained on axial, coronal, and sagittal planes was used for the segmentation of the tongue in MRI scans of the head. The 3D volumes were processed slice-wise across the three orientations and the predictions were merged using different voting strategies. This approach was developed using MRI datasets from 20 patients with 'classical' spinal amyotrophic lateral sclerosis (ALS) and 20 healthy controls and, in a pilot study, applied to the tongue volume quantification to 19 controls and 19 ALS patients with the variant progressive bulbar palsy (PBP). Consensus models with softmax averaging and majority voting achieved highest segmentation accuracy and outperformed predictions on single orientations and consensus models with union and unanimous voting. At the group level, reduction in tongue volume was not observed in classical spinal ALS, but was significant in the PBP group, as compared to controls. Utilizing single U-Net trained on three orthogonal orientations with consequent merging of respective orientations in an optimized consensus model reduces the number of erroneous detections and improves the segmentation of the tongue. The CNN-based automatic segmentation allows for accurate quantification of the tongue volumes in all subjects. The application to the ALS variant PBP showed significant reduction of the tongue volume in these patients and opens the way for unbiased future longitudinal studies in diseases affecting tongue volume.",

Generally, Fisher syndrome follows a self-limited course with a good prognosis. Ophthalmoplegia, typically bilateral, progresses to complete external ophthalmoplegia within 1-2 weeks. Ataxia, often very severe, may cause an inability to walk without support despite normal strength. Fisher syndrome is also frequently concomitant with additional clinical features, including ptosis, internal ophthalmoplegia, facial nerve palsy, sensory deficits, and bulbar palsy. The confirmation of an antecedent infection is often established. Among the ganglioside antibodies, anti-GQ1b antibodies exhibit positivity in over 80% of patients. The syndrome manifests in three distinct types: a partial subtype exhibiting only a subset of the triad symptoms, Bickerstaff's brainstem encephalitis marked by impaired consciousness and pyramidal tract signs, and an overlapping subtype with Guillain-Barr\u00e9 syndrome, characterized by weakness in the extremities.",

He had noticed contractures of the fingers of both hands from the age of 18. Examination revealed a skin rash including heliotrope rash and Gottron's sign, joint contractures in the extremities, dysphagia, extensive muscle weakness and marked muscle atrophy. The serum creatine kinase level was 272\u2005\u200dIU/l and muscle biopsy showed typical perifascicular atrophy but little lymphocyte invasion. There was no interstitial pneumonia or malignancy, but muscle tendons showed elevated CT values suggesting calcification or fibrosis. Anti-nuclear matrix protein 2 (NXP-2) antibody-positive dermatomyositis was diagnosed on the basis of the serum antibody level. Methylprednisolone pulse therapy ameliorated the skin rash and bulbar palsy, but muscle weakness, atrophy and joint contractures were resistant to the treatment. There have been no previous reports of young adults with anti-NXP-2 antibody-positive dermatomyositis in whom joint contracture became evident as early as 4 years beforehand, which is a important feature for differential diagnosis of dermatomyositis.",

The study included 35 sporadic (ALS) patients (cases), and 35 healthy age and sex-matched participants (controls) aged <60 years. SSR was recorded in the electrophysiology lab of the Neurology Department of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh. Patients with diseases associated with peripheral or autonomic neuropathy were excluded. Prolonged latency (delayed SSR) or an absent response was considered abnormal SSR. SSR was found to be abnormal in 17 (48.6 %) ALS cases, with an absent response in the upper limbs of six cases (17.1%). Abnormal SSR was more prevalent in the lower limbs, with 33 (94.3%) and 20 (57.1%) cases having a delayed or absent response, respectively. In comparison, SSR was normal in all control participants (P-value <0.05). Abnormal SSR was significantly more common in the lower limbs of ALS cases with bulbar palsy than those without bulbar palsy (P-value=0.04). There was no association of SSR with disease severity and duration. ALS is significantly associated with abnormal SSR, indicating autonomic nervous system involvement. There could also be an association between bulbar palsy and abnormal SSR among ALS patients. Further studies should be carried out to determine the association of abnormal SSR with disease severity, duration, and type.",

We evaluate the outcome of GBS patients with bulbar palsy, and also compare the risks and benefits of intubation and MV in them. 187 GBS patients with bulbar palsy from a cohort of 547 GBS registry were analyzed. Detailed clinical records and peak disability on a 0-6 GBS Disability Scale (GBSDS) were noted. The patients were intubated if arterial blood gas (ABG) analysis revealed hypoxia, hypercarbia or acidosis. The patients with normal ABG parameters were fed by nasogastric tube, and nursed in lateral position. Occurrence of pneumonia, in-hospital death and outcomes at 6-months were classified as complete (GBSDS <2), partial (GBSDS 2-3) and poor (GBSDS >3). 76/187(40.6%) patients required MV, and they had a shorter duration of illness (p = 0.007), higher peak disability (p < 0.001), autonomic dysfunction (p < 0.001) and more frequently received IVIg (p = 0.02). Pneumonia (63% vs 10.8%; p < 0.001) and in-hospital deaths (7.9% vs 1.8%; p = 0.06) were more frequent in MV group compared to nasogastric fed group. At 6-months,104 (55.6%) patients recovered completely. On multivariate analysis, the independent predictors of poor outcome were peak disability [Adjusted Odds Ratio (AOR) 9.84, 95% Confidence Interval (CI) 3.15-30.74, p < 0.0001], day of hospitalization from disease onset (AOR 1.09, 95% Cl 1.01-1.01; p=0.009) and requirement of MV (AOR 0.10; 95% 0.02-0.50; p = 0.005). GBS patients with bulbar palsy may be managed by nasogastric feeding and nursing in lateral position without increasing the risk of pneumonia. Mechanical ventilation based on ABG does not worsen outcomes of GBS with bulbar palsy.",

The MND SMART trial aims to test the safety and efficacy of promising interventions efficiently and definitively against a single contemporaneous placebo control group. We now report results of the stage two interim analysis for memantine and trazodone. MND SMART is an investigator-led, phase 3, double-blind, placebo-controlled, multiarm, multistage, randomised, adaptive platform trial recruiting at 20 hospital centres in the UK. Individuals older than 18 years with a confirmed diagnosis of either amyotrophic lateral sclerosis classified by the revised El Escorial criteria, primary lateral sclerosis, progressive muscular atrophy, or progressive bulbar palsy, regardless of disease duration, were eligible for screening. Participants were randomised (1:1:1) to receive oral trazodone 200 mg once a day, oral memantine 20 mg once a day, or matched placebo using a computer-generated minimisation algorithm delivered via a secure web-based system. Co-primary outcome measures were clinical functioning, measured by rate of change in the Amyotrophic Lateral Sclerosis Functional Rating Scale Revised (ALSFRS-R), and survival. Comparisons were conducted in four stages, with predefined criteria for stopping at the end of stages one and two. We report interim analysis from the stage two results, which was done when 100 participants per group (excluding long survivors, defined as >8 years since diagnosis at baseline) completed a minimum of 12 months of follow-up for the candidate investigational medicinal products. The trial is registered on the European Clinical Trials Registry, 2019-000099-41, and ClinicalTrials.gov, NCT04302870, and is ongoing. Between Feb 27, 2020, and July 24, 2023 (database lock for interim analysis two), 554 people with a motor neuron disease were randomly allocated to memantine (183 [33%]), trazodone (185 [33%]), or placebo (186 [34%]). The primary interim analysis population comprised 530 participants, of whom 175 (33%) had been allocated memantine, 175 (33%) had been allocated trazodone, and 180 (34%) had been allocated placebo. Over 12 months of follow-up, the mean rate of change per month in ALSFRS-R was -0\u00b7650 for memantine, -0\u00b7625 for trazodone, and -0\u00b7655 for placebo (memantine versus placebo estimated mean difference 0\u00b7033, one-sided 90% CI lower level -0\u00b7085; one-sided p=0\u00b736; trazodone vs placebo: 0\u00b7065, -0\u00b7051; one-sided p=0\u00b724). The one-sided p values were both above the significance threshold of 10%, indicating that neither memantine nor trazodone groups met the criteria for continuation. There were 483 participants with at least one adverse event (145 [77%] on placebo, 170 [91%] on memantine, and 168 [90%] on trazodone). There were 88 participants with at least one serious adverse event (37 [20%] on memantine, 27 [14%] on trazodone, and 24 [13%] on placebo). A total of 11 serious adverse event led to treatment discontinuation. There was no survival difference between comparisons, with 49 deaths in the memantine group, 52 deaths in the trazodone group, and 48 deaths in the placebo group. Neither memantine nor trazodone improved efficacy outcomes compared with placebo. This result is sufficiently powered to warrant no further testing of trazodone or memantine in motor neuron disease at the doses evaluated in this study. The multiarm multistage design shows important benefits in reducing the time, cost, and participant numbers to reach a definitive result.

Overlap between these variants can pose a diagnostic challenge. We report a case of finger drop variant and acute bulbar palsy overlap as an unusual manifestation of GBS. An 81-year-old man presented with dysarthria, dysphagia, and upper limb weakness. Neurological examination revealed impaired tongue protrusion, the finger drop sign, and diminished brachioradial and triceps muscle reflexes. Nerve conduction studies showed reduced amplitudes and decreased velocities in the median and ulnar nerves. Cerebrospinal fluid analysis revealed albuminocytological dissociation and an anti-ganglioside antibody study revealed positivity for GM1, asialo-GM1, GT1a, GD1b, and GQ1b. As GBS was suspected, we initiated intravenous immunoglobulin treatment, resulting in gradual improvement within the next 3 weeks. To the best of our knowledge, this is the first reported case of an overlap between the finger drop variant and acute bulbar palsy in GBS, highlighting the importance of considering GBS when patients present with a combination of atypical symptoms. Anti-ganglioside antibodies can be helpful and add diagnostic value in these complex cases.",

Five representative cases from the author's first 20 years at Chiba University Hospital and its affiliated hospitals were selected, including a patient of respiratory-onset who was ignorantly extubated by a female relative for patient's distress to the intratracheal tube. Based on the latter 20 years of experience at the author's current hospital, the author first describes a famous patient with ALS who was being treated at this medical center before the author was assigned to this hospital and fought against ALS for 31 years before eventually succumbing to total locked-in syndrome. Thereafter, the author has summarized the ages, sex, phenotypes, comorbidities, responses to the available treatment options, and total number of years that have elapsed for the 24 patients that the author initially examined in the outpatient clinic. In terms of diagnostic delay, the author describes \"foot drop\" in patients who developed lower limb symptoms, and hoarseness in those who developed bulbar palsy. Furthermore, the author discusses issues regarding family caregiving capacity, patient's and families' understanding of notification, and medical management (i.e., medications, rehabilitation for ADL, nutrition and respiration, complications of frontotemporal dementia, and medical cooperation with other clinics and hospitals).",

Tractopathy, or damage to these tracts, can impair sensory or motor functions. Motor neuron diseases are pathologic processes affecting the upper or lower motor neurons. Amyotrophic lateral sclerosis (ALS) is the most common form of acquired motor neuron disease. Traditionally, ALS has affected upper and lower motor neurons of the extremities, torso, and head and neck. There are several ALS variants, some of which affect only the upper motor neurons (eg, primary lateral sclerosis), lower motor neurons (eg, progressive muscular atrophy), or motor neurons of the head and neck (eg, progressive bulbar palsy). Characteristic imaging features of ALS include abnormal T2 hyperintensity within the brain along the corticospinal tract, as well as cortical susceptibility signal intensity along the precentral gyrus, termed the \"motor band\" sign. Spinal muscular atrophy is a less common primary motor neuron disease and appears on images as atrophy of the anterior horn of the spinal cord, as well as proximal muscle atrophy. In addition to pure motor neuron diseases, there are numerous toxic and metabolic conditions, genetic disorders, infectious diseases, and immune-mediated disorders that can secondarily affect the corticospinal tracts (corticospinal tractopathies), producing symptoms of upper motor neuron injury. These tractopathies are visible at MRI as T2-hyperintense lesions along varying segments of the corticospinal tract. A comprehensive diagnostic approach that integrates clinical symptoms with radiologic and laboratory findings is crucial to distinguish among these varied conditions. \u00a9RSNA, 2024 Supplemental material is available for this article.",

Data of children who met GBS diagnostic criteria were evaluated retrospectively. The sample was divided into three binary subgroups according to severe GBS (Hughes Functional Grading Scale [HFGS] \u2265 4 at admission), mechanical ventilation (MV) requirement, and poor prognosis (inability to walk independently, HFGS \u2265 3 after six months). Various clinical, laboratory and electrophysiological parameters were compared between these subgroups. The mean age of 63 children with GBS was 91.55\u00b149.09 months. 13 (20.6%) patients required MV and 4 (6.3%) patients died. Associated risk factors for the need for MV in severe GBS were found to be autonomic dysfunction, bulbar palsy, sensory impairment, lowest total Medical Research Council (MRC) scale for muscle strength score at admission, high modified Erasmus GBS respiratory failure score (mEGRIS), high neutrophil-lymphocyte ratios (NLR) and high systemic immune-inflammation index (SII) values (p<0.001, p=0.003, p=0.033, p<0.001, p<0.001, p=0.037 and p=0.042, respectively). The lowest total MRC scale for muscle strength score at admission was a significant indicator of poor prognosis (p<0.001). Autonomic dysfunction, bulbar palsy, sensory impairment, lowest total MRC scale for muscle strength score at admission, high mEGRIS score, high NLR and SII values are potential risk factors for the need for MV in children with severe GBS. The lowest total MRC scale for muscle strength score at admission was associated with poor prognosis.",

        "39823474": "ID: 39823474\nTitle: Tail Anchored protein insertion mediated by CAML and TRC40 links to neuromuscular function in mice.\nAbstract: Motor neuron diseases, such as amyotrophic lateral sclerosis (ALS) and progressive bulbar palsy, involve loss of muscle control resulting from death of motor neurons. Although the exact pathogenesis of these syndromes remains elusive, many are caused by genetically inherited mutations. Thus, it is valuable to identify additional genes that can impact motor neuron survival and function. In this report, we describe mice that express globally reduced levels of calcium-modulating cyclophilin ligand (CAML) protein. CAML is an essential component in the transmembrane domain recognition complex (TRC) pathway, responsible for inserting C-terminal tail anchored (TA) proteins into the endoplasmic reticulum membrane. The primary phenotype observed in these mice was rapid development of hind limb weakness and paralysis. Spinal cord sections revealed a loss of motor neuron cell bodies. Targeting CAML loss specifically to neurons using SLICK-H-Cre or synapsin-Cre transgenic mice yielded similar phenotypes, indicating that CAML plays a cell autonomous role in this process. We found that intracellular trafficking was perturbed in cells depleted of CAML, with aberrant release of procathepsin D and defective retention of CD222 within the trans-Golgi network, as well as reduced levels and mislocalization of syntaxin 5 (Stx5). Dysfunctional lysosomes and abnormal protein glycosylation were also revealed in CAML deficient cells, further indicating a defect in Golgi trafficking. In addition, we observed an identical phenotype in mice lacking ASNA1 in neurons, suggesting that CAML's role in sustaining muscle function is related to its involvement in the TRC pathway. Together, these findings implicate motor neuron survival as a key role for the TA protein insertion machinery in mice, which may shed light on the pathogenesis of neuromuscular disease in humans.",

From early stage in the disease, vital capacity (VC), lung insufflation capacity (LIC) and ALS Functional Rating Scale-Revised scores were regularly measured, and LVRT was continuously performed at home. After 10 years, the patient had complete limb function loss and required nutritional management via gastrostomy and full assistance with daily activities. Despite this, the gap between VC and LIC remained approximately 2000 mL, and the patient was not ventilator-dependent during the day after tracheostomy. Chest CT showed improvement in lower lobe atelectasis due to LVRT. Typically, respiratory physiotherapy is challenging in patients with bulbar palsy or post-tracheostomy, but in this case, LVRT successfully maintained lung mobility. Early LVRT implementation may improve ALS patients' survival prognosis and warrants further exploration.",

Although clinically, radiologically, and pathologically similar, they were caused by mutation of two different genes. As the rarity of the two diseases, the differential diagnosis of them was difficult. 23 CSF1R-L and 6 AARS2-L patients were enrolled from the Leukoencephalopathy Clinic, Peking Union Medical College Hospital in China. Detailed clinical information, neuroimaging manifestations, and genetic data were collected and analyzed. Demographically, female patients were more in AARS2-L than CSF1R-L. Clinically, cognitive impairment and emotion/personality change were common in both groups. Bulbar palsy, extrapyramidal symptoms, and hemiplegia/pyramidal impairment were more common in CSF1R-L, while ataxia was significantly more common in AARS2-L. Abnormal menstruation including infertility was significantly more in AARS2-L. Radiologically, similar features were found, including lateral ventricle-centered white matter lesions, involving corpus callosum, avoiding U fibers. The lesions showed persistent hyperintensity on DWI image and were not contrasted after gadolinium enhancement. In CSF1R-L, the lesions could be widespread confluent or patchy and spotted, extending to centrum semiovale and subcortical white matter occasionally, which was significantly different from AARS2-L. Besides, brain stem lesion caused by pyramidal degeneration, spotted or linear calcification and obviously brain atrophy were common in CSF1R-L. In AARS2-L, periventricular white matter rarefaction was significantly common. No genotype and phenotype association was found in these two diseases. Although similar, there were several clinical and radiological features helping differentiating the two distinct diseases.",

Both syndromes present with ophthalmoplegia and ataxia. However, BBE is differentiated by altered consciousness or pyramidal signs (central nervous system involvement), while MFS has areflexia (peripheral nervous system involvement). Here, we discuss a case of an elderly woman, who, after an initial episode of upper respiratory tract infection, developed bilateral ophthalmoplegia, facial and bulbar palsy, ataxia, depressed consciousness and areflexia. She was diagnosed clinically as a case of BBE-MFS overlap. However, serology was negative for anti-GQ1b antibodies, and brain imaging and cerebrospinal fluid (CSF) analysis were normal. Despite initial clinical deterioration and the need for intubation, she was treated successfully with intravenous immunoglobulin and eventually recovered. This case demonstrates that BBE and MFS can overlap and that early clinical diagnosis becomes essential even if anti-ganglioside antibodies, CSF and imaging studies are negative.",

HIV infection can cause an MND-like syndrome due to central nervous system (CNS) involvement de novo or during antiretroviral therapy (ART) due to CNS escape. We present two cases: one with a classic amyotrophic lateral sclerosis (ALS) phenotype, which was the manifestation of symptomatic CNS escape from ART, and the second with a primary lateral sclerosis (PLS) phenotype associated with underlying HIV infection. A systematic review of published literature of people living with HIV (PLHIV) who developed ALS/ MND was conducted using the PubMed, Embase, and Lilacs databases. A total of 91 cases were found, 89 of which were obtained from 37 articles, and two were included from our own case series. In patients with HIV-associated MND, 63 patients reviewed had a classic ALS phenotype followed by progressive muscular atrophy variant (12), progressive bulbar palsy (8), PLS (7) and bulbar onset ALS (1). Neuroimaging, electrophysiology, cerebrospinal fluid (CSF) analysis, CSF and serum HIV viral load, and CD4 count investigations were used for diagnosis. Following the initiation or modification of antiretroviral therapy (ART), approximately 70% exhibited an improvement or a stable disease course. HIV-associated MND is a rare condition that can occur in both ART-naive individuals and those on treatment. A proportion of cases (~\u200970%) show improvement with ART.

A 75-year-old female developed rapidly progressive symptoms, including bilateral non-reactive mydriasis, ptosis, complete ophthalmoplegia, bilateral facial weakness, tongue immobility, palatal paralysis, limb dysmetria, ataxia, and brisk generalized tendon reflexes, all while maintaining a preserved mental state. Symptoms emerged 10 days after a probable gastrointestinal infection. Severe bulbar dysfunction necessitated orotracheal intubation and a tracheotomy. Extensive cranial nerve involvement initially suggested a brainstem lesion, with oculomotor and acute bulbar palsy as prominent signs. However, brainstem and spinal magnetic resonance imaging along with cerebrospinal fluid analysis yielded negative results. Electromyography reveled a sensorimotor demyelinating polyradiculoneuropathy, and serum testing identified IgG antibodies targeting multiple gangliosides, including the disialosyl group and terminal NeuNAc(\u03b12-3)Gal. Treatment with intravenous immunoglobulin (IVIG) led to gradual clinical improvement. This case highlights a rare and severe GBS phenotype characterized by reactivity to multiple gangliosides.

We collected data for children with anti-GM1 antibody-positive GBS spectrum disorders in Affiliated Children's Hospital of Chongqing Medical University between July 2018 and March 2024; 1:1 matching was performed for combined anti-ganglioside or anti-sulfatide antibody. The patients underwent comparative clinical characterization to determine the antibody phenotype-clinical phenotype and to analyze the possible risk factors for the poor prognosis of the disorders. Thirty-seven pediatric patients were recruited. Anti-GM1 antibody-positive GBS spectrum disorders were preceded by a prodromal event (25 of 37, 67.6%). The first symptom was mainly limb weakness (20 of 37, 54.1%), which could be predominately accompanied by autonomic nerve involvement (21 of 37, 56.8%). Seven features showed statistically significant differences (P\u00a0<\u00a00.05) between the positive group and the negative one, including cranial nerve involvement, bulbar palsy, low lower limb muscle strength at discharge, axonal type of electrophysiological typing, and clinical typing of acute motor axonal neuropathy. The GBS disability scores at discharge and at one month after discharge were higher than those in the control group. The shorter time to peak (<7.5\u00a0days) was identified as an independent risk factor for poor short-term prognosis of the disorders. Anti-GM1 antibody-positive GBS spectrum disorders have a relatively specific antibody phenotype-clinical phenotype. The shorter time to peak (<7.5\u00a0days) is an independent risk factor for poor short-term prognosis of the disorders in children.",

Data from patients who had undergone EDX test/s between 2010 and 2019 at a tertiary centre were retrospectively analysed, including final neuromuscular diagnoses, EDX results and demographic information. EDX data included motor and sensory nerve conduction study, needle electromyography (EMG), repetitive nerve stimulation and stimulated single fiber EMG. Final clinical diagnosis was based on several investigations including muscle biopsy, MR imaging, gene testing, EDX-tests and clinical phenotype. 351 patients were identified (56\u00a0% male, average age 42.5\u00a0months), with diagnoses categorised into the following groups: no identifiable neuromuscular disorders (45\u00a0%), neuropathy (13\u00a0%), motor neuron disease (9\u00a0%), isolated bulbar palsy (6\u00a0%), myopathy (14\u00a0%), neuromuscular junction disorders (5\u00a0%), and critical illness neuromyopathy (8\u00a0%). EDX data was stratified into 7 electrodiagnostic categories: normal, neuropathy, motor neuron disease, isolated bulbar palsy, myopathy, neuromuscular junction disorders, and critical illness neuromyopathy. With this stratification we were able to predict the final diagnosis with acceptable accuracy. The prevalence of neuromuscular disease groups in paediatric ICU was defined together with their corresponding EDX characteristics. The study confirms the utility of electrophysiology as a valuable tool for diagnosing and managing neuromuscular conditions in paediatric ICU.",
        "40364643": "ID: 40364643\nTitle: Latest progress and challenges in drug development for degenerative motor neuron diseases.\nAbstract: Motor neuron diseases are sporadic or inherited fatal neurodegenerative conditions. They selectively affect the upper and/or lower motor neurons in the brain and spinal cord and feature a slow onset and a subacute course contingent upon the site of damage. The main types include amyotrophic lateral sclerosis, progressive muscular atrophy, primary lateral sclerosis, and progressive bulbar palsy, the pathological processes of which are largely identical, with the main disparity lying in the location of the lesions. Amyotrophic lateral sclerosis is the representative condition in this group of diseases, while other types are its variants. Hence, this article mainly focuses on the advancements and challenges in drug research for amyotrophic lateral sclerosis but also briefly addresses several other important degenerative motor neuron diseases. Although the precise pathogenesis remains elusive, recent advancements have shed light on various theories, including gene mutation, excitatory amino acid toxicity, autoimmunology, and neurotrophic factors. The US Food and Drug Administration has approved four drugs for use in delaying the progression of amyotrophic lateral sclerosis: riluzole, edaravone, AMX0035, and tofersen, with the latter being the most recent to receive approval. However, following several phase III trials that failed to yield favorable outcomes, AMX0035 has been voluntarily withdrawn from both the US and Canadian markets. This article presents a comprehensive summary of drug trials primarily completed between January 1, 2023, and June 30, 2024, based on data sourced from clinicaltrials.gov. Among these trials, five are currently in phase I, seventeen are in phase II, and eleven are undergoing phase III evaluation. Notably, 24 clinical trials are now investigating potential disease-modifying therapy drugs, accounting for the majority of the drugs included in this review. Some promising drugs being investigated in preclinical studies, such as ATH-1105, are included in our analysis, and another review in frontiers in gene therapy and immunotherapy has demonstrated their therapeutic potential for motor neuron diseases. This article was written to be an overview of research trends and treatment prospects related to motor neuron disease drugs, with the aim of highlighting the latest potentialities for clinical therapy.",

Data from 95 patients with severe GBS were classified into two groups based on the Hughes functional grading scale (HFGS) on day 28: those with poor prognosis (>3) and those with prognosis (\u22643). Clinical characteristics, nerve conduction studies and blood parameters were compared at admission between the two groups. Logistic regression analysis identified predictive factors for GBS, and receiver operating characteristic (ROC) curves were used to evaluate the predictive efficacy. A nomogram model combining these predictive factors was constructed and evaluated using ROC and calibration curves and Hosmer\u2043Lemeshow goodness-of-fit test. The poor prognosis group exhibited bulbar paralysis and an elevated modified Erasmus GBS Outcome Score (mEGOS) (P < 0.05). Nerve conduction studies revealed increased numbers of inexcitable motor nerves (IMN) in the poor prognosis group. Blood analysis showed significantly elevated neutrophil-to-lymphocyte ratio (NLR) during acute disease stage (P < 0.05) compared with the good prognosis group. ROC curve analysis indicated that mEGOS, NLR value, IMN number, and their combination had area under the curve (AUC) values of 0.818, 0.757, 0.870, and 0.947, with sensitivities of 78.4 %, 76.5 %, 75.0 %, and 92.2 %, and specificities of 77.3 %, 77.3 %, 61.3 %, and 86.4 % respectively, for short-term prognosis prediction. The nomogram model demonstrated an area under the ROC curve of 0.990, reflecting good potential clinical effect. The calibration curve showed good agreement between actual observations and nomogram predictions. The findings indicate that early assessment of the occurrence of bulbar palsy, mEGOS, IMN numbers, and NLR value can predict poor prognosis, with their combination providing improved accuracy for short-term prognosis in patients with severe GBS.",

It follows a progressive course, typically characterized by sensorineural deafness, facial weakness, ponto-bulbar palsy, ataxia, and peripheral sensory-motor neuropathy. This disease is\u00a0often associated with childhood mortality if left untreated.\u00a0We report the case of a 68-year-old woman who first noticed a mild hearing loss at the age of 12. This was followed by a slowly progressive onset of bilateral facial paresis, dysarthro-dysphonia, stridor, and tongue atrophy with fasciculations. At 63 years of age, genetic testing revealed a single heterozygous variant in the SLC52A3 gene.\u00a0Although typically autosomal recessive,\u00a0some individuals with classic symptoms and even response\u00a0to riboflavin therapy have been found to carry only a single mutation in either the SLC52A2 or SLC52A3 gene. Therefore, given the\u00a0compatible clinical presentation, a diagnosis of\u00a0BVVLS was considered after discussion with a center of expertise.\u00a0Consequently,\u00a010 mg/kg/day of riboflavin supplementation\u00a0was prescribed for three years, but no significant clinical improvement was observed. Currently, at age 68, the patient is on nocturnal non-invasive mechanical ventilation (NIV)\u00a0and uses assisted airway clearance techniques, including air-stacking maneuvers and mechanical insufflation-exsufflation on demand, due to respiratory compromise secondary to diaphragmatic weakness and vocal cord paralysis. This unique presentation of slowly progressive symptoms and long survival may be related to the single heterozygous SLC52A3 variant found. Respiratory care in BVVLS is currently adapted from other neuromuscular disorders with stronger evidence bases.\u00a0This case highlights the critical role of pulmonology in BVVLS care, including clinical and functional monitoring, early initiation of NIV, and the implementation of airway clearance techniques.",

Clinicians must remain vigilant for neuroinvasive illness in patients presenting with febrile symptoms and malaise following mosquito exposure. While magnetic resonance imaging and cerebrospinal fluid analysis aid in differential diagnosis, detecting West Nile immunoglobulin M in serum is crucial for definitive diagnosis. Treatment primarily involves supportive care due to the absence of established regimens, though promising outcomes have been reported with plasma exchange and intravenous immunoglobulin. We present the case of an 83-year-old resident of Alabama, an avid gardener living near a pond, who initially exhibited symptoms of productive cough, diarrhea, fever, and generalized malaise. However, within 48 h, he developed hypoxemia, functional quadriplegia, and bulbar palsy necessitating intubation. Diagnostic evaluations, including magnetic resonance imaging and positive West Nile virus immunoglobulin M in serum, confirmed West Nile virus-associated poliomyelitis viral syndrome, prompting intravenous immunoglobulin therapy. This case highlights the importance of promptly identifying and managing West Nile virus infection, especially in regions susceptible to mosquito-borne diseases, and being vigilant of the disease in non-endemic regions. The case also begs the question of the timing and efficacy of intravenous immunoglobulin and plasma exchange in West Nile virus infection and the fact that more data should be collected on these therapies.",

This rare syndrome is challenging to diagnose, particularly in preterm infants. This report describes a low-birth-weight female infant with WDS who had no sucking reflex from birth, airway obstruction due to saliva retention and muscle rigidity, who was diagnosed with the syndrome at a postconceptional age (PCA) of 1\u2009month. She was discharged with only home oxygen therapy as respiratory support at a PCA of 3 months after gradual improvement in her clinical symptoms. Diagnosis of WDS is difficult in the early postnatal period in preterm cases owing to prematurity but should be suspected when bulbar palsy, including absence of the sucking reflex, persistent dysphagia and obstructed breathing, persists beyond a PCA of 40 weeks and when muscle stiffness is present.",

A 23-year-old man presented with persistent hiccups, pneumonia, and progressively worsening respiratory dysfunction. Clinical course and imaging findings raised strongly suggested bulbar palsy from a C4-5 intramedullary hemorrhagic lesion. Computed tomography and magnetic resonance imaging of the brain and cervical spine revealed an intramedullary mass at C4-5, accompanied by syringobulbia and syringomyelia, with signals extending from the lower medulla oblongata to the T1 spinal level. The patient underwent laminectomy, myelotomy, and microsurgical mass excision with intraoperative neurophysiological monitoring. Postoperative pathology confirmed the lesion as an ependymoma. Neurologic function improved steadily after surgery. Thus, central respiratory dysfunction should be considered in patients with severe pneumonia without underlying disease. Additionally, contrast-enhanced magnetic resonance imaging is essential for differential diagnosis in bulbar palsy cases.",

We describe the case of a 64-year-old previously healthy, immunocompetent man who presented with acute bulbar symptoms (difficulty swallowing, change in phonation, and drooling). His symptoms progressed in severity and he ultimately required intubation due to declining lung function and inability to manage his secretions. Clinical examination revealed bulbar dysfunction without involvement of other cranial nerves. A lumbar puncture revealed albuminocytological dissociation: elevated protein (9.8\u00a0g/L), nonerythroid cell count (13 cells/\u00b5L) with predominantly lymphocytic count. He received a five-day course of intravenous immunoglobulin for presumed Guillain-Barr\u00e9 syndrome. Initial magnetic resonance imaging (MRI) showed mild microangiopathic changes in the brain with no parenchymal, leptomeningeal, or cranial nerve enhancement. Cerebrospinal fluid (CSF) analysis was positive for varicella zoster virus (VZV). He was treated with intravenous Acyclovir 10\u00a0mg/kg three times daily for 14 days with no initial improvement and underwent a tracheostomy. Subsequent MRI was consistent with rhombencephalitis.

        "40802071": "ID: 40802071\nTitle: Biallelic variants in DNAJC7 cause familial amyotrophic lateral sclerosis with the TDP-43 pathology.\nAbstract: Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by the progressive degeneration of motor neurons. ALS pathology primarily involves the failure of protein quality control mechanisms, leading to the accumulation of misfolded proteins, particularly TAR DNA-binding protein 43 (TDP-43). TDP-43 aggregation is a central pathological feature of ALS. Maintaining protein homeostasis is critical and facilitated by heat shock proteins (HSPs), particularly the HSP40 family, which includes co-chaperones such as DNAJC7. Here, we report a family with three siblings affected by ALS who carry a homozygous c.518dupC frameshift variant in DNAJC7, a member of the HSP40 family. All three patients exhibited progressive muscle weakness, limb atrophy, bulbar palsy, and respiratory failure. Pathological examination revealed degeneration of both upper and lower motor neurons, with phosphorylated TDP-43-positive neuronal cytoplasmic inclusions in the frontal and temporal cortices. Immunoblot analysis were consistent with a type B pattern of phosphorylated TDP-43 in the precentral gyrus. Immunohistochemistry and RNA sequencing analyses demonstrated a substantial reduction in DNAJC7 expression at both the protein and RNA levels in affected brain regions. In a TDP-43 cell model, DNAJC7 knockdown impaired the disassembly of TDP-43 following arsenite-induced stress, whereas DNAJC7 overexpression suppressed the assembly and promoted the disassembly of arsenite-induced TDP-43 condensates. Furthermore, in a zebrafish ALS model, dnajc7 knockdown resulted in increased TDP-43 aggregation in motor neurons and reduced survival. To the best of our knowledge, this study provides the first evidence linking biallelic loss-of-function variants in DNAJC7 to familial ALS with TDP-43 pathology.",

Methods: A case series study was conducted, including 25 children diagnosed with serum anti-GT1a antibody-positive GBS at Guangzhou Women and Children's Medical Center from March 2019 to December 2024. Clinical data, treatment protocols, and follow-up outcomes were analyzed. Mann Whitney U test was used to compare the changes in Hughes functional grading scale (HFGS). Results: A total of 25 children included 12 boys and 13 girls, and the age at first onset was (71\u00b18) months. There were 16 children (64%) had preceding infections, and of which 13 children had predominantly respiratory tract infections. At disease peak, neurological manifestations included limb weakness (21 cases (84%)), bulbar palsy (13 cases (52%)), drowsiness (7 cases (28%)), limb pain (9 cases (36%)), ataxia (6 cases (24%)), respiratory muscle paralysis (5 cases (20%)), ophthalmoplegia (5 cases (20%)), and unilateral facial nerve palsy (4 cases (16%)). Cerebrospinal fluid analysis in 23 children revealed albuminocytological dissociation in 18 children. All 25 children underwent whole-spine magnetic resonance imaging (MRI), demonstrated spinal nerve root enhancement in 18 children, with leptomeningeal enhancement combined with spinal nerve root enhancement in 1 child. Electromyography in 16 children showed 15 children abnormality, of which demyelinating lesions in 8 children, mixed demyelinating-axonal changes in 4 children, and pure axonal involvement in 3 children. Intravenous immunoglobulin (IVIG) was administered to 21 cases (84%), of which 3 children required mechanical ventilation and blood purification (plasma exchange in 2 children and immunoadsorption in 1 child) due to disease progression. Four children (16%) received intravenous methylprednisolone (IVMP) instead of IVIG, with 1 child requiring ventilatory support due to respiratory muscle paralysis, and the tracheal tube was removed after continued sequential IVMP treatment. The hospitalization duration of 25 children was (23\u00b13) d. At discharge, HFGS was 1.6 (0.6, 2.7) score. At a follow-up of 12 (4, 18) months, HFGS was 0.1 (0.0, 0.5) score, and higher than that at discharge (Z=4.38, P<0.05). Two children relapsed but achieved remission after IVIG retreatment with no recurrence during 1-year follow-up. Conclusions: Anti-GT1a antibody-positive GBS in children predominantly presents with limb weakness and bulbar palsy, occasionally complicated by respiratory failure in the acute phase. Demyelinating neuropathy and spinal nerve root enhancement on MRI are characteristic. IVIG therapy yields favorable outcomes, with low residual disability. Relapses are rare but manageable with re-treatment. \u76ee\u7684\uff1a \u603b\u7ed3\u513f\u7ae5\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u7684\u4e34\u5e8a\u7279\u70b9\u3001\u6cbb\u7597\u53ca\u9884\u540e\u3002 \u65b9\u6cd5\uff1a \u75c5\u4f8b\u7cfb\u5217\u7814\u7a76\uff0c\u9009\u62e92019\u5e743\u6708\u81f32024\u5e7412\u6708\u5728\u5e7f\u5dde\u533b\u79d1\u5927\u5b66\u9644\u5c5e\u5987\u5973\u513f\u7ae5\u533b\u7597\u4e2d\u5fc3\u795e\u7ecf\u5185\u79d1\u4e34\u5e8a\u8bca\u65ad\u4e3a\u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u768425\u4f8b\u60a3\u513f\uff0c\u6536\u96c6\u5e76\u5206\u6790\u5176\u4e34\u5e8a\u8d44\u6599\u53ca\u6cbb\u7597\u968f\u8bbf\u8d44\u6599\u3002\u91c7\u7528Mann-Whitney U\u68c0\u9a8c\u6bd4\u8f83\u60a3\u513fHughes\u529f\u80fd\u5206\u7ea7\u8bc4\u5206\uff08HFGS\uff09\u53d8\u5316\u3002 \u7ed3\u679c\uff1a 25\u4f8b\u60a3\u513f\u753712\u4f8b\u3001\u597313\u4f8b\uff0c\u9996\u6b21\u53d1\u75c5\u5e74\u9f84\u4e3a\uff0871\u00b18\uff09\u6708\u9f84\u300216\u4f8b\uff0864%\uff09\u6709\u524d\u9a71\u611f\u67d3\uff0c\u5176\u4e2d13\u4f8b\u4e3a\u547c\u5438\u9053\u611f\u67d3\u3002\u75be\u75c5\u9ad8\u5cf0\u65f6\u795e\u7ecf\u7cfb\u7edf\u75c7\u72b6\u5305\u62ec\u80a2\u4f53\u65e0\u529b21\u4f8b\uff0884%\uff09\u3001\u7403\u9ebb\u75f913\u4f8b\uff0852%\uff09\u3001\u55dc\u77617\u4f8b\uff0828%\uff09\u3001\u80a2\u4f53\u75bc\u75db9\u4f8b\uff0836%\uff09\u3001\u5171\u6d4e\u5931\u8c036\u4f8b\uff0824%\uff09\u3001\u547c\u5438\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u773c\u808c\u9ebb\u75f95\u4f8b\uff0820%\uff09\u3001\u5355\u4fa7\u9762\u795e\u7ecf\u9ebb\u75f94\u4f8b\uff0816%\uff09\u300223\u4f8b\u60a3\u513f\u8111\u810a\u6db2\u68c0\u67e5\uff0c\u86cb\u767d-\u7ec6\u80de\u5206\u79bb18\u4f8b\u300225\u4f8b\u60a3\u513f\u5168\u810a\u67f1\u78c1\u5171\u632f\u6210\u50cf\uff08MRI\uff09\u68c0\u67e5\u793a\u810a\u795e\u7ecf\u6839\u5f3a\u531618\u4f8b\uff0c\u67d4\u8111\u819c\u5f3a\u5316\u5408\u5e76\u810a\u795e\u7ecf\u6839\u5f3a\u53161\u4f8b\u300216\u4f8b\u60a3\u513f\u63a5\u53d7\u808c\u7535\u56fe\u68c0\u67e5\uff0c15\u4f8b\u5f02\u5e38\uff0c\u5176\u4e2d\u8131\u9ad3\u9798\u75c5\u53d88\u4f8b\u3001\u8131\u9ad3\u9798\u5408\u5e76\u8f74\u7d22\u75c5\u53d84\u4f8b\uff0c\u8f74\u7d22\u75c5\u53d83\u4f8b\u3002\u9759\u8109\u8f93\u6ce8\u514d\u75ab\u7403\u86cb\u767d\uff08IVIG\uff09\u6cbb\u7597 21\u4f8b\uff0884%\uff09\uff0c\u5176\u4e2d3\u4f8b\u60a3\u513fIVIG\u6cbb\u7597\u540e\u75c5\u60c5\u8fdb\u5c55\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\u884c\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u53ca\u8840\u6db2\u51c0\u5316\u6cbb\u7597\uff0c\u5305\u62ec\u8840\u6d46\u7f6e\u63622\u4f8b\u3001\u514d\u75ab\u5438\u9644\u6cbb\u75971\u4f8b\u30024\u4f8b\u60a3\u513f\u62d2\u7eddIVIG\u6cbb\u7597\u63a5\u53d7\u9759\u8109\u8f93\u6ce8\u7532\u6cfc\u5c3c\u9f99\uff08IVMP\uff09\u6cbb\u7597\uff0c\u5176\u4e2d1\u4f8b\u56e0\u547c\u5438\u808c\u9ebb\u75f9\u63a5\u53d7\u6c14\u7ba1\u63d2\u7ba1\u547c\u5438\u673a\u8f85\u52a9\u901a\u6c14\u6cbb\u7597\uff0c\u7ee7\u7eedIVMP\u5e8f\u8d2f\u6cbb\u7597\u540e\u62d4\u9664\u6c14\u7ba1\u63d2\u7ba1\u300225\u4f8b\u60a3\u513f\u9996\u6b21\u53d1\u75c5\u6025\u6027\u671f\u7684\u4f4f\u9662\u65f6\u95f4\u4e3a\uff0823\u00b13\uff09d\uff0c\u51fa\u9662\u65f6HFGS 1.6\uff080.6\uff0c2.7\uff09\u5206\uff0c\u9996\u6b21\u53d1\u75c5\u51fa\u9662\u81f3\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u7684\u65f6\u95f4\u95f4\u9694\u4e3a12\uff084\uff0c18\uff09\u4e2a\u6708\uff0cHFGS 0.1\uff080.0\uff0c0.5\uff09\u5206\uff0c\u672b\u6b21\u95e8\u8bca\u968f\u8bbf\u65f6HFGS\u4f4e\u4e8e\u51fa\u9662\u65f6\uff08Z=4.38\uff0cP<0.05\uff09\u30022\u4f8b\u60a3\u513f\u590d\u53d1\uff0c\u518d\u6b21\u4e88IVIG\u6cbb\u7597\u540e\u7f13\u89e3\uff0c\u968f\u8bbf1\u5e74\u672a\u518d\u590d\u53d1\u3002 \u7ed3\u8bba\uff1a \u8840\u6e05\u6297GT1a\u6297\u4f53\u9633\u6027\u7684\u5409\u5170-\u5df4\u96f7\u7efc\u5408\u5f81\u6025\u6027\u671f\u5e38\u89c1\u7684\u75c7\u72b6\u4e3a\u80a2\u4f53\u65e0\u529b\u53ca\u7403\u9ebb\u75f9\uff0c\u4e25\u91cd\u8005\u53ef\u51fa\u73b0\u547c\u5438\u808c\u9ebb\u75f9\uff0c\u808c\u7535\u56fe\u4ee5\u8131\u9ad3\u9798\u75c5\u53d8\u591a\u89c1\uff0cMRI\u810a\u795e\u7ecf\u6839\u5316\u5e38\u89c1\uff0c\u591a\u6570\u60a3\u513fIVIG\u514d\u75ab\u6cbb\u7597\u6548\u679c\u826f\u597d\uff0c\u65e0\u4e25\u91cd\u795e\u7ecf\u7cfb\u7edf\u540e\u9057\u75c7\u6b8b\u7559\u3002\u5c11\u6570\u60a3\u513f\u53ef\u80fd\u590d\u53d1\u3002.",

AE reports primarily related to EA were retrieved from the US FDA Adverse Event Reporting System database for the fourth quarter of 2021 to the third quarter of 2024. Disproportionality analysis using Reporting Odds Ratio (ROR), Proportional Reporting Ratio (PRR), Bayesian Confidence Propagation Neural Network, and Multi-item Gamma Poisson Shrinker algorithms was employed to detect signals of AEs. Our study processed 3,182 AE reports related to EA, revealing 57 signals that met the criteria of the ROR, PRR, Bayesian Confidence Propagation Neural Network, and Multi-item Gamma Poisson Shrinker algorithms across 14 system organ classes. Notably, the most significant signal in the System Organ Class was \"Surgical and medical procedures\", whereas the most significant signal in Preferred Term was \"Bulbar Palsy\". Some unexpected over-the-counter AEs, including falls, choking, sepsis, nephrolithiasis, and atrial fibrillation, were also observed. The median onset time of EA-related AEs was 101.5 d (interquartile range 27-260). The AE risk model associated with EA should be referred to as \"early failure\", with the likelihood of AEs decreasing over time. This study highlights the potential AEs and risks associated with the clinical use of EA; the analysis provides significant evidence regarding the clinical safety of EA.",
        "41004918": "ID: 41004918\nTitle: Tongue shear wave elastography for bulbar dysfunction in amyotrophic lateral sclerosis.\nAbstract: Amyotrophic lateral sclerosis (ALS) often manifests with tongue involvement, leading to dysarthria and dysphagia. While current diagnostic methods are invasive or qualitative, the development of non-invasive quantitative assessments of tongue function is essential. A prospective study (March 2022 - March 2024) included 38 ALS patients (categorized by bulbar or spinal onset) and 12 controls. Clinical symptoms were evaluated using the Amyotrophic Lateral Sclerosis Functional Rating Scale-Revised (ALSFRS-R). Tongue muscle elasticity was measured using shear wave elastography (LOGIQ\u00ae E9, 9\u00a0MHz). Median shear modulus of the genioglossus (GG) muscle was significantly lower in bulbar-onset ALS (7.80\u00a0kPa, range 5.41-10.08) compared to spinal-onset ALS (12.48\u00a0kPa, range 8.50-21.42) and controls (14.16\u00a0kPa, range 11.37-20.21). The geniohyoid (GH) muscle showed similar patterns. Both muscles showed significantly reduced elasticity in bulbar-onset ALS compared to controls (p\u00a0<\u00a00.05). The GG muscle elasticity showed strong positive correlation with bulbar symptom severity on the ALSFRS-R. Reduced tongue muscle elasticity in bulbar-onset ALS, along with its correlation with bulbar symptoms, suggests the potential utility of this technique for both diagnosis and prognosis. These findings indicate that shear wave elastography is a promising noninvasive tool for the quantitative assessment of tongue dysfunction in ALS.",

In this study, two SLC52A3 variants (NM_033409.4: c.62A\u2009>\u2009G [p.Asn21Ser] and c.161G\u2009>\u2009A [p.Gly54Glu]) were identified in a family with hereditary hearing loss through whole-exome sequencing. The compound heterozygous proband exhibited only late-onset, progressive, and symmetric sensorineural hearing loss over 23\u00a0yr, along with unilateral facial muscle spasm. A heterozygous carrier of the c.62A\u2009>\u2009G variant also exhibited optic nerve dysfunction, while no other neurological abnormalities were observed in the family. Although the proband's decreased serum riboflavin level has been improved through supplementation, no significant clinical improvement was observed. These findings further support the phenotypic variability, incomplete penetrance, and a potential autosomal dominant inheritance pattern of RTD3. We also underscore the importance of early genetic testing, timely and sustained riboflavin supplementation, and long-term follow-up in affected individuals.",
        "41063391": "ID: 41063391\nTitle: Familial ALS With p. L127S (L126S) Variant of the Cu/Zn SOD1 Gene: A Report of Two New Cases and Literature Review.\nAbstract: Herein, we report two autopsy cases of familial ALS with a p. L127S (L126S) SOD1 variant. Case 1 involved a 62-year-old woman who presented with lower-extremity muscle weakness with lower motor neuron signs. The patient developed bulbar palsy and died of respiratory failure 9\u2009years after onset. Case 2 (the second son of Case 1) presented with lower-extremity muscle weakness at the age of 38\u2009years, with upper and lower motor neuron signs and died of respiratory failure 8\u2009years after onset. The pathological findings in both cases predominantly consisted of lower motor neuron loss and degeneration of the lateral and posterior funiculi. Numerous conglomerate hyaline inclusions (CHIs) were observed in the remaining motor neurons. Vacuole formation was observed inside the inclusions, sometimes with granular structures. Some inclusions were positive for ubiquitin, p62, and SOD1. Electron microscopy revealed that CHIs were composed of neurofilaments and expanded mitochondria. By literature review, ALS with p. L127S disclosed a male-dominant incidence rate, a variety of ages at onset, and low penetrance. The initial symptom was exclusively lower limb weakness. One-third of the patients only showed lower motor neuron signs and half did not present with bulbar symptoms. The neuropathological findings commonly observed in ALS with p. L127S variants were mainly the degeneration of lower motor neurons and the sensory system, including the posterior column, Clarke's nucleus, and the associated cerebellar system. The formation of intracytoplasmic hyaline inclusions was also a prominent feature. ALS with p. L127S variant should be included in the possible diagnosis of slowly progressive muscle weakness in the lower extremities, with or without family history or upper motor neuron signs. The loss of lower motor neurons and the accumulation of neurofilaments in the remaining neurons are key to the pathological diagnosis for ALS with p. L127S variant.",
        "41090254": "ID: 41090254\nTitle: A Case of Miller-Fisher Overlap Syndrome With Positive Anti-GM4 Antibody and Atypical Symptoms.\nAbstract: Miller-Fisher syndrome (MFS) is a recognized clinical variant of Guillain-Barr\u00e9 syndrome (GBS), characterized by the classic triad of ophthalmoplegia, ataxia, and areflexia. When accompanied by additional symptoms such as bulbar palsy, limb weakness, or lethargy, it is termed MFS overlap syndrome. This report describes a male patient diagnosed with MFS overlap syndrome, presenting with ophthalmoplegia, ataxia, bulbar palsy, numbness in both arms, positive GM4 IgG antibodies, a persistent, intractable headache, and a delayed onset of left-sided peripheral facial palsy. The patient had a preceding suspected case of chlamydial pneumonia before symptom onset, and his condition improved significantly following treatment with intravenous immunoglobulin. This case suggests that chlamydial pneumonia might predispose individuals to GBS. Patients with MFS/pharyngeal-cervical-brachial (PCB) overlap syndrome may exhibit atypical symptoms, including persistent, intractable headaches, and delayed peripheral facial paralysis. Atypical symptoms should not delay the diagnosis and treatment of GBS once other conditions have been adequately excluded. The presence of anti-GM4 antibodies, often found alongside other anti-ganglioside antibodies, may serve as a critical immunological factor in MFS/PCB overlap syndrome.",
        "41103821": "ID: 41103821\nTitle: A Hospitalist's Challenge: Systemic Botulism Following a Cosmetic Injection Requiring Antitoxin Therapy and Percutaneous Endoscopic Gastrostomy (PEG).\nAbstract: Botulinum toxin type A (BoNT-A) is widely used in cosmetic practice and generally considered safe, with adverse effects usually limited to transient local reactions. Rarely, systemic spread or counterfeit formulations can cause iatrogenic botulism, presenting with bulbar weakness and generalized neuromuscular dysfunction. We report the case of a 53-year-old woman who developed progressive dysphagia, bilateral ptosis, bifacial weakness, and proximal muscle weakness following cosmetic BoNT-A injections to the face and masseter muscles. Imaging and endoscopic evaluations were unremarkable, and myasthenia gravis (MG) was excluded. Despite initial\u00a0partial improvement on pyridostigmine, her bulbar dysfunction worsened, necessitating administration of botulinum antitoxin and eventual percutaneous endoscopic gastrostomy (PEG) placement for nutritional support. Over subsequent weeks, she demonstrated gradual recovery, though mild ptosis persisted at discharge. This case underscores the potential for systemic botulism after cosmetic BoNT-A, particularly in the setting of unregulated or counterfeit products. Physicians must maintain a high index of suspicion in patients with recent cosmetic injections presenting with cranial or bulbar symptoms, as timely recognition and antitoxin therapy are essential to optimize outcomes and reduce morbidity.",

Coexistence of GBS and MG or chronic inflammatory demyelinating polyneuropathy and MG, particularly the low-density lipoprotein receptor-related protein 4 (LRP4) antibody-positive subtypes, is extremely rare. We present such a case to highlight diagnostic challenges. A 46-year-old man presented with distal weakness, sensory loss, facial diplegia, and dyspnea. Nerve conduction studies revealed demyelinating features, and cerebrospinal fluid analysis showed albuminocytologic dissociation. An acute demyelinating polyneuropathy, most likely GBS, was suspected, and clinical improvement was observed following plasmapheresis. Three weeks later, new symptoms including dysarthria and worsening bulbar weakness emerged. Repetitive nerve stimulation showed a decremental response. LRP4 antibodies were positive, confirming MG. The patient improved with intravenous immunoglobulin, corticosteroids, pyridostigmine, and azathioprine. This case underscores the rare coexistence of acute demyelinating polyneuropathy and LRP4-positive MG. In acute demyelinating polyneuropathy patients with relapsing or worsening symptoms, coexisting MG should be considered. Comprehensive electrophysiological evaluation and antibody testing, including LRP4, are essential for the accurate diagnosis of both conditions.",

We describe an 80-year-old man with unresectable HCC who received dual durvalumab and tremelimumab on a non-STRIDE schedule. Within four weeks, he developed ptosis, diplopia, and bulbar weakness that rapidly progressed to neuromuscular respiratory failure. Laboratory evaluation revealed markedly elevated creatine kinase, troponin, and aldolase levels, along with a strongly positive acetylcholine receptor antibody. Despite treatment with high-dose corticosteroids, intravenous immunoglobulin, and plasma exchange, neurologic recovery was limited, and he experienced recurrent respiratory decline. After confirming decision-making capacity, he chose to discontinue life-prolonging therapy and transitioned to hospice. This case highlights the fulminant potential of myasthenia-myositis overlap after programmed death-ligand 1 (PD-L1) plus cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) blockade, underscores the importance of early biomarker surveillance and rapid escalation to immunomodulatory therapy, and illustrates the need for early goals-of-care discussions in patients facing severe immune-related toxicities.",

        "41241894": "ID: 41241894\nTitle: Rapid Bolus Inflow into the Esophagus in a Patient with a Tracheostomy after Surgical Treatment for Dysphagia.\nAbstract: This report describes a case in which a patient with an open tracheostomy, following surgery for severe dysphagia, acquired vacuum swallowing and exhibited rapid bolus inflow into the esophagus. A 39-year-old man with bulbar palsy caused by medullary surgery demonstrated impaired pharyngeal contraction and upper esophageal sphincter opening. After undergoing laryngeal suspension and cricopharyngeal myotomy, videofluoroscopic evaluation of swallowing revealed rapid passage of the bolus from the pharynx into the esophagus. High-resolution manometry demonstrated markedly negative intraesophageal pressure accompanied by simultaneous elevation of lower esophageal sphincter pressure during swallowing. These findings suggest that the patient had spontaneously acquired vacuum swallowing despite the presence of a tracheostoma communicating with the atmosphere. Recognition of this compensatory mechanism is important because it may facilitate bolus transport in individuals with tracheostomy. Increased awareness of this swallowing pattern may prevent underdiagnosis and offer new insights into rehabilitation strategies for dysphagia.",
        "41285215": "ID: 41285215\nTitle: Altered dimerization of certain riboflavin transporter 2 mutants: a possible source of UPR, altered calcium signalling and mitochondrial derangements in RTD2.\nAbstract: Riboflavin transporter deficiency Type 2 (RTD2, OMIM #614707), formerly known as Brown-Vialetto-Van Laere Syndrome 2 (BVVLS 2), is a rare autosomal recessive neurodegenerative disorder caused by biallelic variants in the SLC52A2 gene, encoding for riboflavin transporter 2 (RFVT2). This transporter plays a critical role in flavin cofactor delivery, particularly in the brain. Clinically, RTD2 presents with progressive hearing loss, optic atrophy, muscle weakness, respiratory issues, and pontobulbar palsy. Current treatment involves high-dose riboflavin and other supplements. In this study we explored the molecular mechanisms behind RTD2, focusing on the dimerization of RFVT2 and the associated cellular stress mechanisms in patient-specific models. We demonstrated that RFVT2 exists as a homodimer and that pathogenic variants significantly impair its dimerization, which may contribute to the induction of ER stress. This hypothesis was supported by elevated levels of BiP, an ER stress marker, in patient iPSC-derived motor neurons. Similar findings were confirmed in patient-derived fibroblasts, where we also observed mitochondrial dysfunction and disrupted calcium signaling. Interestingly, no significant changes in FAD content were detected in both cell models, suggesting that proteotoxic stress may be a crucial pathogenic mechanism in RTD2, even in the absence of signs of FAD deficiency.

These findings provide insight into the pathogenic mechanisms of RTD2, highlighting the critical role of RFVT2 misfolding, ER stress, and mitochondrial dysfunction in this neurodegenerative disorder.",
        "41295274": "ID: 41295274\nTitle: Riboflavin Transporter Deficiency as a Cause of Progressive Encephalopathy.\nAbstract: Background/Objective: Riboflavin transporter deficiency (RTD) is a rare neurodegenerative disease, with under 500 cases genetically confirmed since the early 2000s. Thus far, three separate subtypes of RTD2 are described-type 1, 2 and 3-but, previously, RTD was classified as two separate genetic defects: Brown-Vialetto-Van Laere syndrome and Fazio-Londe syndrome, caused by mutations in the SLC52A2 and SLC52A3 genes, respectively. The most prominent symptoms found in patients include encephalopathy, expressed as peripheral and cranial nerve neuropathy, which in turn lead to a series of complications: decreased muscle strength, hypotonia, visual impairment, sensorineural hearing loss, bulbar palsy, sensory ataxia and respiratory insufficiency secondary to diaphragmatic paresis. At the cellular level, riboflavin is modified into active flavin cofactors: FMN, mediating riboflavin phosphorylation through riboflavin kinase, and FAD, involved in FMN adenylation through the flavin dinucleotide 1 synthesis. FMN and FAD are two of approximately 100 proteins collectively described as the 'flavoproteome'. Most of them are mitochondrial oxidoreductases, catalyzing the electron transport in many metabolic reactions, as well as regulating important cell processes, such as the production of reactive oxygen species, protein conformation and damage repair. FMN and FAD are also responsible for the conversion of B6 and B9 vitamins into their active forms, which allows for healthy cell growth and immune function. Methods: In this article, the authors describe two children, a 6-year-old girl and her 5-year-old sister, both presenting with RTD2 caused by mutations in the SLC52A2 gene (c.916G>C (p.Gly306Arg); c.477C>G (p.Cys159Trp)), in whom the disease progression was successfully inhibited by vitamin B2 supplementation in varying doses. Results: Their clinical image consists of psychomotor developmental delay, ataxia, horizontal nystagmus, hearing loss and a lack of visual fixation. Conclusions: The phenotype and clinical signs presented by the described sisters are further discussed in relation to the previously published reports of RTD2 cases.",

The classical form manifests as an ascending, symmetrical weakness, but atypical variants, including descending presentations, have been increasingly recognized. Such variants often pose diagnostic challenges and are associated with more severe disease and prolonged recovery. We describe a 70-year-old woman with well-controlled hypertension who presented with progressive dysphagia, pooling of saliva, and upper limb weakness. Clinical examination revealed bulbar dysfunction, areflexia in the upper limbs, and motor power in the upper limbs was markedly reduced to grade 1/5 on the Medical Research Council (MRC) scale, while lower limb strength was preserved. Within hours of admission, the weakness progressed to quadriplegia with respiratory distress, necessitating intubation and mechanical ventilation. Cerebrospinal fluid analysis demonstrated albumin cytological dissociation, and nerve conduction studies revealed changes consistent with GBS. Intravenous immunoglobulin was initiated but discontinued due to anaphylaxis; therapeutic plasma exchange was subsequently performed. The patient had marked cardiovascular lability and, after one month, acute colonic pseudo-obstruction (ACPO), which resolved with conservative management. Around the 40th day, she experienced complete left lung collapse due to mucus plugging, which was successfully managed with bedside bronchoscopy. Persistent bulbar dysfunction delayed decannulation until day 80. Remarkably, full neurological recovery was achieved only after six months of follow-up. This case highlights several atypical and severe features of GBS: descending onset with bulbar involvement at presentation, multisystem autonomic dysfunction extending to the gastrointestinal tract, and a protracted course despite early immunotherapy and supportive care. The unusually delayed onset of ACPO and persistent bulbar palsy underscores the need for vigilance beyond the acute phase. Hence, clinicians should maintain a high index of suspicion for atypical variants of GBS in patients with acute, progressive weakness, even when the presentation deviates from the classical ascending pattern. A structured, multimodal diagnostic approach and timely initiation of therapy are essential to prevent complications. Severe variants may follow a prolonged recovery trajectory, requiring sustained multidisciplinary management.",

He studied medicine in Paris from 1826 to 1831 and later established a practice in Boulogne. In 1835, he observed isolated muscular contractions produced by electropuncture and began investigating the electrical excitation of muscle. In 1842, he left Boulogne for Paris to continue medical research, often visiting hospitals with his electrical equipment to examine unusual cases. He was an inventive investigator who developed several technical innovations, including electrodiagnosis, electrotherapy, needle muscle biopsy, and medical photography. He enumerated his major discoveries in \"L'Electrisation Localisee,\" which included descriptions of progressive muscular atrophy (now called spinal muscular atrophy), atrophic paralysis of childhood (poliomyelitis), progressive locomotor ataxia (tabes dorsalis), glosso-labio-laryngeal paralysis (progressive bulbar palsy), and pseudohypertrophic paralysis (Duchenne muscular dystrophy). Based on Duchenne's intensive investigations, Jean-Martin Charcot refined his medical concepts and established nosological disease entities, calling Duchenne \"mon ma\u00eetre en neurologie\" (my master in neurology). Duchenne never held a hospital or university position. He died of cerebrovascular disease on September 17, 1875.",
        "41366746": "ID: 41366746\nTitle: Safety and efficacy of botulinum toxin injection for sialorrhea in amyotrophic lateral sclerosis: a systematic review and meta-analysis.\nAbstract: INTRODUCTION: Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease, with 80% of ALS patients experiencing bulbar weakness at some stage of the disease. ALS patients with bulbar weakness often suffer from troublesome sialorrhea. Botulinum toxin injection, as a neuromuscular blocker, has been widely used in the treatment of sialorrhea. This paper evaluates the safety and efficacy of botulinum toxin injections for the treatment of sialorrhea in ALS patients through a systematic review and meta-analysis. METHODS: A systematic review and meta-analysis was conducted by searching eight databases, including PubMed, EMBASE, and CNKI, up to April 13, 2025. Eligible randomized controlled trials and quasi-experimental studies were analyzed using Review Manager 5.4 and Stata software. RESULTS: Thirteen studies (2 RCTs, 11 quasi-experimental studies) with 130 ALS patients were included. Botulinum toxin significantly reduced sialorrhea and improved quality of life (Z\u2009=\u200910.98, p\u2009<\u20090.00001; RD\u2009=\u20090.82, 95% CI: 0.67\u20130.97). The treatment effect was independent of toxin type (p\u2009=\u20090.48), injection site (p\u2009=\u20090.17), and ultrasound guidance use (p\u2009=\u20090.44). CONCLUSION: Botulinum toxin appears to be a safe and effective option for managing sialorrhea in ALS patients, regardless of injection technique. However, given that most included studies were observational, further validation through high-quality RCTs is warranted. TRIAL REGISTRATION: This meta-analysis has been registered with Prospero, and the registration number is CRD420251029441. The registration period is April 9, 2025.",
        "41421983": "ID: 41421983\nTitle: Dengue virus infection and Guillain-Barr\u00e9 syndrome: a systematic review of clinical characteristics, outcomes, and predictors of severity.\nAbstract: BACKGROUND: Dengue virus (DENV) is a mosquito-borne flavivirus causing significant morbidity in tropical and subtropical regions. While not classically neurotropic, DENV has been increasingly associated with neurological complications, including Guillain\u2013Barr\u00e9 syndrome (GBS). This review synthesizes evidence on epidemiology, clinical features, outcomes, and predictors of severity in dengue-associated GBS. METHODS: We systematically searched PubMed and Embase (April 2025) using terms for dengue and GBS. Eligible studies were case reports/series with individual-level data on laboratory-confirmed or clinically diagnosed dengue preceding GBS. RESULTS: Thirty-six publications describing 56 patients from Asia, Latin America, and other endemic regions were included. The mean age was 34.9 years (range 1.5\u201373), with 57% male. 95% had symptomatic dengue; thrombocytopenia occurred in 43%. Median latency from dengue onset to GBS was 7 days. Motor weakness was universal; facial palsy (32%), bulbar weakness (28.6%), sensory deficits (33.9%), and autonomic dysfunction (18%) were common. Electrophysiology showed AMSAN (33.9%), AIDP (32.1%), and AMAN (12.5%). Albuminocytologic dissociation was present in 62.5% of CSF samples. IVIG was administered in 76.7%, plasmapheresis in 14.3%; 25% required mechanical ventilation. Outcomes were favorable in most: 57% achieved full recovery, 32% partial recovery, and 5.4% mortality. CONCLUSIONS: Dengue-associated GBS resembles other post-infectious forms but shows a high proportion of axonal subtypes. Prognosis is generally good with standard therapy. Although severe cases, particularly those with thrombocytopenia, are more likely to require ICU care. Clinicians in endemic areas should maintain a high index of suspicion for GBS in the post-dengue period to enable timely diagnosis and management.",

Classical GBS typically presents with ascending symmetrical weakness and areflexia, while atypical variants, such as Miller Fisher Syndrome (MFS) and the Pharyngeal-Cervical-Brachial (PCB) variant, show distinct clinical patterns that are often under-recognized, particularly in resource-limited settings. This report describes a rare case of a 45-year-old previously healthy woman who developed progressive ophthalmoplegia, bulbar weakness, neck flexor weakness, and proximal upper limb weakness, along with areflexia, following a mild upper respiratory tract infection. Sensory function and lower limb motor strength remained intact. The differential diagnoses included brainstem stroke, myasthenia gravis, and diphtheritic polyneuropathy. Cerebrospinal fluid analysis revealed albuminocytologic dissociation, and nerve conduction studies showed a demyelinating sensorimotor polyneuropathy predominantly affecting the upper limbs. The presence of anti-GQ1b and anti-GT1a IgG antibodies supported an immune-mediated process. A diagnosis of GBS with overlapping MFS and PCB variants was established. The patient received a five-day course of intravenous immunoglobulin along with supportive management. Her neurological function gradually improved, with complete recovery noted at the three-month follow-up. This case highlights the importance of early recognition of overlapping GBS variants, especially in patients with cranial nerve and upper limb involvement. Greater clinical awareness and improved access to ganglioside antibody testing may facilitate earlier diagnosis and better outcomes. The coexistence of MFS and PCB variants also reinforces the concept of GBS as a spectrum disorder with shared underlying mechanisms.",

In addition, increasing evidence indicates that SBMA is a multisystem disorder with prominent non-motor symptoms, such as sensory neuropathy, androgen insensitivity, and glucose intolerance. This study aimed to further characterize the clinical manifestations and biomarker profile in a large Swedish SBMA cohort. 49 genetically confirmed SBMA patients were identified from a motor neuron disease database at Ume\u00e5 University Hospital, Sweden. CAG repeat length in the androgen receptor (AR) gene was assessed by RP-PCR. Blood samples were analyzed for cardiovascular and muscle biomarkers. Clinical data were collected from medical records and interviews, with autopsy findings reviewed in two cases. The mean CAG repeat length was 43.1, with a mean age at motor symptom onset of 58.6\u00a0years. Notably, 19% of patients initially presented with sensory symptoms. High prevalence of hypertonia (70%), diabetes mellitus (39%), and cardiac disease (38%) was observed. Elevated troponin levels were common, and pNfL (neurofilament light chain in plasma) was elevated in seven patients, likely reflecting combined cerebrovascular and cardiovascular comorbidity. Importantly, two of these seven patients exhibited rapid disease progression, and a concomitant diagnosis of ALS was confirmed histopathologically. This cohort was characterized by a relatively low number of AR gene CAG repeats and a late onset of motor symptoms. Sensory symptoms frequently occurred before motor decline. Cardiovascular disease and diabetes were common comorbidities and, in some cases, preceded neurological symptoms. These findings underscore the need for improved clinical awareness of the heterogeneous presentation of SBMA and support routine cardiovascular monitoring to reduce diagnostic delays and prevent early mortality.",

Primary motor neuronopathies are characterized by progressive degenerative loss of anterior horn cell motoneurons (lower motor neurons) or loss of giant pyramidal Betz cells (upper motor neurons). Rare atypical variants of MND-ALS include flail arm syndrome (FA), flail leg syndrome (FL), facial-onset sensory and motor neuronopathy (FOSMN), finger extension weakness and downbeat nystagmus motor neuron disease (FEWDON-MND) and long-standing and juvenile MND-ALS.

Damage to the posterior part of the inferior frontal gyrus and inferior part of precentral gyrus play a role in the pathogenesis of FCMS. We report a rare case of bilateral OPS following an acute right middle cerebral artery (MCA) infarct in a patient with history of glioblastoma, and resection in the left MCA territory within the cingulate gyrus, showing recovery of speech and swallowing despite intensive bilateral opercular lesions owing to extensive multidisciplinary team support. However, the patient was discharged with a percutaneous endoscopic gastrostomy tube for long-term enteral feeding support due to partial recovery. The patient's history of glioblastoma, left MCA cingulate gyrus resection and right MCA infarction with automatic-voluntary dissociation led to the diagnosis of FCMS. Rehabilitation surprisingly showed mild improvement in speech and swallowing despite extensive bilateral opercular lesions proving that there are still chances of improvement in speech and swallowing in OPS with the right multidisciplinary approach. Patients with a history of brain tumours like glioblastoma can develop bilateral OPS later in life in case of other vascular events that cause lesions in a previously unaffected operculum, triggering symptoms. Extensive involvement of the speech and language team is of significant in the management of FCMS cases as above where some recovery might still be seen. Foix-Chavany-Marie syndrome (FCMS) can be caused by bilateral opercular lesions (new or old or a combination of both) in patients with history of high-grade brain tumours.Patients with bilateral opercular syndrome experience full or partial or no recovery at all of speech and swallowing, hence proper rehabilitation with a Speech and Language Team is significant.Understanding automatic-voluntary dissociation in FCMS and being able to differentiate it from bulbar palsy and other similar phenomena is crucial in making a diagnosis of FCMS.",

However, its specific link to bulbar muscle weakness and short-term outcomes is not well established. This study aimed to investigate the prevalence of subjective sleep disorder (based on Pittsburgh Sleep Quality Index [PSQI] score) in a cohort of acetylcholine receptor (AChR) antibody-positive MG patients, and to explore its associations with bulbar muscle weakness, disease severity, and its value for the short-term outcome of MG. We conducted a prospective cohort study of 163 AChR-MG patients. Subjective sleep quality was assessed using the PSQI score. Disease severity was evaluated with MG Specific Activities of Daily Living (MG-ADL) score, the Quantitative MG (QMG) score, and Myasthenia Gravis Foundation of America (MGFA) classification. Univariate and multivariable logistic regression were used to identify independent risk factors and establish prediction model for outcome. The predictive values were evaluated by receiver operating characteristic (ROC) curves. Moreover, calibration analysis and decision curve analysis (DCA) of the model were performed. The median PSQI score was 7.0 (5.0, 9.0) and the prevalence of sleep disorder (PSQI > 5) was 73.6\u00a0%. Patients with bulbar weakness had significantly higher PSQI scores than those without (P < 0.001). PSQI score showed significant positive correlations with MG-ADL (r\u00a0=\u00a00.319, P < 0.001),QMG (r\u00a0=\u00a00.356, P < 0.001) in MG patients. A higher baseline PSQI score was identified as an independent risk factor for poor outcome at 6\u00a0months (odds ratio: 1.642 [95\u00a0% CI: 1.340-2.014], P < 0.001), with a area under curve (AUC) of 0.797. A predictive model combining PSQI score, bulbar weakness, and female gender demonstrated good discrimination, with a AUC of 0.840, a sensitivity of 0.688, and a specificity of 0.870. Poor sleep quality is highly prevalent in AChR-MG and was more serious in patients with bulbar weakness. PSQI score was an independent risk factor for poor short-term outcome. Routine assessment of sleep may aid in risk stratification and personalized management.",

Myasthenia gravis (MG) is an autoimmune disorder characterized by fatigable weakness due to acetylcholine receptor (AChR) antibodies. We describe a 74-year-old man with coronary artery disease, chronic kidney disease, and prostate cancer who developed progressive dysphagia, dysphonia, ptosis, and neck weakness. Initial attribution to medication-related angioedema delayed recognition. Neurological examination revealed bulbar weakness and fatigable ptosis. Electrodiagnostic testing confirmed post-synaptic neuromuscular junction dysfunction, and AChR antibody assays were strongly positive across binding, blocking, and modulating subtypes. Concurrent Lyme serologies were positive for immunoglobulin G and immunoglobulin M. The patient required intensive care monitoring and was treated with plasma exchange, intravenous ceftriaxone, prednisone, and pyridostigmine, with marked improvement.

This approach quickly improved symptoms, achieved minimal symptom expression (MSE), and allowed faster tapering of corticosteroids and pyridostigmine. While multiple studies have demonstrated the efficacy and safety of efgartigimod, large-scale studies remain necessary to further evaluate the feasibility of combination therapy with rituximab in MuSK-Ab-positive MG.",

METHODS: Our study analyzed clinical factors linked to pneumonia in GBS patients through a retrospective review of 101 individuals admitted to Tianjin Huanhu Hospital between January 2020 and December 2023. Patients were divided into two groups based on pneumonia development after admission: GBS with pneumonia (n\u2009=\u200919) and GBS without pneumonia (n\u2009=\u200982). Clinical and blood parameters were compared between the groups. Logistic regression analysis identified predictive factors for pneumonia in these GBS patients. RESULTS: Significant associations were found between pneumonia and older age (P\u2009=\u20090.01), bulbar palsy (P\u2009=\u20090.017), mechanical ventilation (MV) support (P\u2009<\u20090.01), hypoalbuminemia (P\u2009<\u20090.01), hyponatremia (P\u2009<\u20090.01), and underlying conditions (P\u2009=\u20090.008). Multivariate logistic regression identified bulbar palsy, MV support and hyponatremia as significant independent risk factors for pneumonia. Finally, GBS patients with pneumonia experienced longer hospital stays and worse functional outcomes. CONCLUSIONS: We initially identified key risk factors for pneumonia in GBS, highlighting its association with poorer prognoses.",

Patients diagnosed with ALS who underwent first PEG insertion between January 2011 and December 2020 were eligible. Medical records were retrospectively reviewed to determine clinical characteristics and outcomes (\u226414 days) of patients who underwent the pull type PEG. Grouping was performed based on the presence and severity of complications, and SPSS 27.0 statistical software was used for data analysis. Finally, Logistic regression model was applied for multivariate factor analysis of risk factors related to complications. In the study, 192 cases of PEG were all successfully completed, with 97 (51%) males, mean age of ALS onset disease (55\u00b111) years and 93 (48%) bulbar onset symptoms included. Complications occurred in 40 (21%) cases after PEG within 14 days, all of which had fever, including 16 cases without clear infection focus, 18 cases of respiratory tract infections, and 6 cases of fistula site infections. In the study, 13 (7%) cases had major complications, including 11 cases of respiratory tract infection and 2 cases of stoma infection. Two cases of respiratory tract infection died due to respiratory failure, and the remaining 11 cases recovered after upgraded antibiotic. No complications, such as tube dislodgement, benign pneumoperitoneum, hemorrhage or buried bumper syndrome occurred. The operation time and postoperative hospital stay were longer in the complication group than in the non-complication group [(16\u00b15) min vs. (13\u00b15) min, P < 0.001; 6 (5, 9) d vs. 5 (3, 7) d, P=0.009].

Further, Logistic regression model analysis revealed that the operation time was also independent associated with complications (OR=1.132, 95%CI: 1.051-1.220, P=0.001). PEG was a reliable method for ALS patients to put nutrition tube. Postoperative fever was the most common complications.

While genetics plays a clear role in a subset of cases, it cannot explain why symptoms start focally or how upper (UMN) and lower motor neuron (LMN) systems are linked. Here, we examined the clinicopathological relationships between UMN and LMN disease in ten ALS patients. Detailed clinical assessments were obtained and tissues from the motor cortex, brainstem, and spinal cord were collected via a rapid autopsy protocol. Tissues were stained for UMN/LMN, myelin, axons, microglia, and pTDP43. Total RNA-sequencing was performed in the medulla, cervical, and lumbar spinal cords from each patient to identify pathways enriched at sites of disease onset. None of the patients had symptoms of frontotemporal dementia (FTD), but all had focal sites of clinical onset and spasticity, indicating both UMN and LMN involvement. Postmortem examination showed LMN degeneration and microglial activation were highest at sites of disease onset. In contrast, UMN degeneration of the corticospinal tract (CST) was present equally at all levels of the spinal cord up through the medulla, regardless of the site of disease onset. Surprisingly, there was no evidence of UMN degeneration of cortical motor neurons or their projecting axons above the brainstem. Similarly, while extensive pTDP43 aggregates were seen in degenerating LMNs, no pTDP43 aggregates were seen in UMN cell bodies or their axons. Mechanistically, RNA-sequencing implicated inflammatory pathways, especially at sites of disease onset. Our findings suggest that many ALS patients without FTD have a dying back of UMN axons, independent of the site of disease onset, which stops in the brainstem with preservation of cortical motor neurons and their proximal axons. Our findings suggest that UMN axonal degeneration can be directly triggered by LMN degeneration and inflammation.",

This study describes the epidemiology, disease trajectory, and changes in clinical management of ALS in a county of Norway over a 38-year period. We conducted a retrospective chart review of all ALS cases diagnosed between 1986 and 2024 in Tr\u00f8ndelag county, Norway. Data were extracted from medical records using a standardized electronic case report form. Patients were stratified by time of diagnosis into four groups. A total of 429 patients were included (56% male). Median age at symptom onset was 68\u2009years. The age-standardized incidence of ALS was 3.32 per 100,000 person-years (95%CI 2.90-3.74) and increased over time (p = 0.002). Bulbar onset occurred in 38% of cases. Median diagnostic delay was 13\u2009months (95%CI 12-14), without significant improvement over time. Median survival was 28\u2009months (95%CI 26-31) from symptom onset, shorter among bulbar-onset patients. Use of riluzole, percutaneous endoscopic gastrostomy, and noninvasive ventilation (NIV) increased over the study period, whereas median survival remained stable. Emergency initiation of ventilation occurred in 25% (NIV n\u2009=\u200941/167) and 89% (invasive ventilation n\u2009=\u200916/18) of cases in which these treatment modalities were used. This comprehensive regional study reveals a rising incidence of ALS in Tr\u00f8ndelag, with increased adoption of supportive interventions over time.",

Few studies have examined the usefulness of ultrasonographic tongue thickness measurement in patients with ALS, but its association with physiological measures remains unclear. Ten patients with ALS underwent tongue thickness measurement using ultrasonography. Clinical assessments including the Korean version of the ALS Functional Rating Scale-Revised (K-ALSFRS-R), Functional Oral Intake Scale (FOIS), Eating Assessment Tool-10 (EAT-10), Dysphagia Handicap Index, Korean version of the Swallowing Quality of Life Questionnaire, Mini Nutritional Assessment-Short Form (MNA-SF), handgrip strength, and bioelectrical impedance analysis for skeletal muscle index (SMI) were performed. Swallowing physiology was evaluated using the Modified Barium Swallow Impairment Profile (MBSImP), Penetration-Aspiration Scale. Simple and partial Pearson's correlation analyses as well as univariate regression were performed with adjustments for age, sex, and body mass index (BMI). Tongue thickness showed significant associations with multiple functional and systemic measures in the unadjusted analyses, including FOIS, EAT-10, MNA-SF, BMI, SMI, K-ALSFRS-R. After adjustment, the most consistent associations were observed with the MBSImP oral, pharyngeal, and combined phase scores. Tongue ultrasonography may serve as a radiation-free method to preliminarily assess bulbar involvement in ALS. Tongue thickness was most specifically associated with dysphagia outcomes, particularly MBSImP. Given the feasibility design and small sample size, larger longitudinal studies are warranted to confirm its clinical utility in monitoring the progression of dysphagia in patients with ALS.",
        "41685589": "ID: 41685589\nTitle: Cognitive Dysfunction Is Associated With an Underestimation of Respiratory Function in ALS.\nAbstract: The association between low forced vital capacity (FVC) and cognitive impairment in ALS is ambiguous; it could be due to respiratory dysfunction and/or poor effort from cognitive deficits. We used the objective, non-volitional phrenic nerve motor response amplitude (PAmp) to clarify how cognitive status affects the relationship between diaphragmatic strength and FVC. This retrospective study included 73 patients with ALS followed in our clinic. FVC and PAmp were measured, and cognitive status was assessed with the Edinburgh Cognitive and Behavioral ALS Screen (ECAS). Regression models tested for associations between FVC and distinct ECAS domains and whether these domains influenced the PAmp-FVC relationship. PAmp (\u03b2\u2009=\u20090.58, p\u2009=\u20090.001) and its interaction with an abnormal ECAS's Executive score (\u03b2\u2009=\u2009-0.20, p\u2009<\u20090.045) were significant predictors of FVC. The latter indicated that patients with abnormal executive function had lower FVC than cognitively normal patients at similar PAmp values. Moreover, in patients with abnormal executive function, a reduction in PAmp was associated with a shallower decline in FVC. Severe bulbar dysfunction was also negatively associated with FVC (\u03b2\u2009=\u2009-0.22, p\u2009=\u20090.024). FVC may underestimate respiratory capacity in cognitively impaired patients; therefore, we recommend non-volitional measures when evaluating ALS patients with executive dysfunction.",

Radiological diagnostics primarily serve to systematically exclude treatable mimics and support the clinical and electrophysiological diagnosis. The focus is on amyotrophic lateral sclerosis (ALS); supplementary progressive muscular atrophy (PMA, purely lower motor neuron, LMN disease) and spinal muscular atrophy (SMA). Which imaging signs support the diagnosis of ALS, how do electromyography/magnetic resonance imaging (EMG/MRI) fit into the Gold Coast criteria and which other motor neuron diseases are relevant? Overview of clinical criteria (Gold Coast), genetics and typical MRI findings of the brain, spinal cord and musculature. Gold Coast core: progressive motor deterioration, upper motor neuron (UMN) and LMN signs in \u2265\u202f1 region or LMN in \u2265\u202f2\u00a0regions and exclusion of alternative causes. susceptibility-weighted imaging (SWI) motor band sign as UMN marker; T2/fluid-attenuated inversion recovery (FLAIR) hyperintensities along the corticospinal tract with low sensitivity, moderate specificity; T1 bright tongue as an indication of chronic denervation in bulbar involvement. EMG: detection of subclinical LMN involvement, sometimes limited in UMN-dominant/bulbar courses. PMA: Pure purely LMN symptoms, often continuum to ALS. SMA: Autosomal autosomal recessive (SMN1 deletion). The diagnosis remains primarily clinical; EMG and MRI are supportive. The radiological priority is the exclusion of mimics. The UMN markers increase diagnostic certainty in the context of clinical/EMG findings but do not replace them. Clear findings facilitate classification according to Gold Coast.

Subsequent reports have expanded its phenotypic spectrum, frequently including neurodevelopmental features. Deep brain stimulation of the globus pallidus internus (GPi DBS) has become a therapeutic mainstay; however, most published data are based on single cases or short-term observations, and long-term outcomes remain poorly characterized. We report the clinical course and response to GPi DBS in nine patients with KMT2B variants prospectively followed at two Austrian national reference centers for rare movement disorders. Long-term follow-up data (range: 5-20 years) were available for six patients. Clinical features and treatment outcomes were compared with previously published cohorts. Non-motor features such as developmental delay, intellectual disability, and epilepsy were more frequent in our cohort than in earlier reports. All patients developed generalized dystonia and bulbar involvement over time, emphasizing the progressive nature of the disease. Despite secondary symptom worsening during long-term follow-up, GPi DBS preserved ambulation in three patients and enabled sustained recovery of walking ability in two, maintaining functional independence. Surgical correction of foot deformities further supported mobility. Notably, KMT2B variants were identified upon genetic re-evaluation in two patients previously diagnosed with dyskinetic cerebral palsy. Our long-term data underscore the progressive but heterogeneous course of DYT-KMT2B. GPi DBS offers durable clinical benefits, particularly when initiated before loss of ambulation. Early surgical intervention and multidisciplinary management are essential to optimize long-term outcomes.",

We present a prehospital resuscitation case involving complete airway obstruction leading to cardiopulmonary arrest in a young patient with myasthenia gravis. A 21-year-old Han Chinese female patient with a reported history of myasthenia gravis developed sudden respiratory arrest during oral intake. The diagnosis of myasthenia gravis was initially provided by on-scene witnesses (classmates), and later confirmed by family who reported her medication regimen. Prehospital interventions-including modified Heimlich maneuvers, rapid endotracheal intubation, and advanced cardiac life support-achieved return of spontaneous circulation within 10\u00a0minutes. Persistent hypoxia and hemodynamic instability were managed during transport. The patient was transferred to the hospital intensive care unit but subsequently died due to the consequences of prolonged cerebral hypoxia. Myasthenia-gravis-associated bulbar weakness predisposes patients to catastrophic aspiration events. This case highlights three critical prehospital strategies: (1) modified supine-position Heimlich maneuvers for intubated arrest patients, (2) time-critical airway clearance using direct laryngoscopy, and (3) multidisciplinary coordination between telemedicine dispatchers and field responders. Our findings highlights the unique challenges of managing airway obstruction in patients with myasthenia gravis and proposes an integrated prehospital strategy for airway management. This case underscores that successful prehospital return of spontaneous circulation is possible in patients with myasthenia gravis with acute airway obstruction; however, prevention remains paramount due to the risk of fatal outcomes. It emphasizes the need for integrated prehospital strategies, patient education on aspiration risk, and protocolized airway algorithms for neuromuscular disorders.",

Based on rehabilitation interventions, stellate ganglion block (SGB) might improve swallowing function by regulating sympathoexcitation and cerebral perfusion. This study explored the short- and long-term effects of SGB on swallowing function, anxiety, and cerebral blood flow in patients with bulbar palsy after ischemic stroke. This randomized double-blind placebo-controlled trial included 124 participants in rehabilitation departments from March 2024 to July 2025 in China. The participants were randomized 1:1 to SGB or placebo groups, and all received routine treatment for 10 consecutive days. The SGB group received SGB with lidocaine hydrochloride, whereas the placebo group received block with normal saline. The primary outcome was the clinical severity of dysphagia. The secondary outcomes were airway protection, forward and upward movement distances of the hyoid bone, accumulation of secretions, pharyngeal residue, anxiety, and mean blood flow velocity (Vm) and internal diameter of the vertebral artery. The Vm and internal diameter were additionally assessed one hour after the first SGB. Repeated measures ANOVA and generalized estimating equations were used to explore time, group, and their interaction effects. There were no significant baseline inter-group differences. After treatment, significant (P\u2009<\u20090.001) interaction effects were observed for dysphagia severity (\u03b72\u2009>\u20090.06), movement distances of the hyoid bone (\u03b72\u2009>\u20090.19), airway protection (\u03b2\u2009= -\u20090.774), pharyngeal residue (\u03b2\u2009< -\u20090.54), accumulation of secretions (\u03b2\u2009= -\u20090.371), and anxiety (\u03b72\u2009=\u20090.462). These effects remained significant at follow-up. After the first SGB, the Vm and internal diameter of the vertebral artery on the SGB side significantly increased (P\u2009<\u20090.001) in the SGB group, but the inter-group differences were non-significant after the intervention period. In patients with bulbar palsy after ischemic stroke who receive routine treatment, SGB is safe and can effectively improve swallowing function, airway protection, and anxiety. The effects of SGB on vertebral artery blood flow are temporary, but the functional impacts are long-term. ClinicalTrials.gov. (Unique identifier: NCT06319534, 20/03/2024).",

Therefore, we aim to develop and validate a clinical prediction model to predict respiratory failure risk in pediatric GBS patients in China, alongside the economic immunological biomarkers in decision-making, and evaluate the Erasmus GBS Respiratory Insufficiency Score (EGRIS)-Kids score's efficacy. The retrospective study originated from our pediatric GBS cohort at Children's Hospital of Chongqing Medical University during 2014-2022. We utilized logistic regression to identify predictors and construct a nomogram and web-based dynamic nomogram. The net reclassification index and integrated discriminant improvement index were used to compare models after incorporating new indices, with bootstrapping validation. Our study included 175 children, among which 23 (13%) patients have developed respiratory insufficiency. Variables included in our score were: age (odds ratio [OR] 1.23), bulbar palsy (OR 23.17), bilateral hip flexion (OR 0.75), and platelet-to-lymphocyte ratio (PLR; OR 2.47). The area under the receiver operating characteristic curve of the nomogram was 0.899 (95% confidence interval 0.839-0.960). The calibration plots showed an adequate consistency between the reported and predicted occurrence. The EGRIS-Kids model yielded an area under the receiver operating characteristic curve of 0.849 (95% confidence interval 0.754-0.944) in our cohort and the incorporation of PLR exhibited an incremental value of 12.51% (P = 0.03). We performed the first external validation of the EGRIS-Kids score in Chinese children with GBS. Furthermore, we developed a new predictive model incorporating the PLR, which shows promise and additional value but requires further external validation.",

The endoscopic endonasal approach (EEA) has improved their treatment. Large multi-center data across different healthcare systems on outcomes following EEA resection of NFPA are limited. We aimed to provide highly generalizable benchmark outcomes from an international, multi-center review of EEA for NFPA resection. Institution-level data on symptoms, tumor and intraoperative characteristics, complications, and long-term outcomes were obtained from four tertiary pituitary centers located in the United States (2), Italy (1), and Austria (1). Means and weighted averages were used to generate descriptive statistics of patient characteristics and outcomes. A total of 1,097 patients who underwent EEA for NFPA were included (mean age: 55.3 years). Presenting symptoms included vision loss (55.2%) and headache (42.1%). The most common preoperative endocrinopathies were hyperprolactinemia (26%) and hypothyroidism (18%). The gross total resection rate was 66%. Patients presenting with headache and visual symptoms experienced improvement (81 and 89%, respectively). Common complications included delayed hyponatremia (7.5%), transient arginine vasopressin deficiency (AVP-D; 6.6%), cerebrospinal fluid leak (3.5%), new endocrinopathy (3.5%), and new cranial nerve palsy (0.8%). There were no instances of carotid artery injury. Stroke (0.4%) and death (0.1%) were exceedingly rare. During the mean follow-up of 30 months, <5% of patients underwent reoperation or radiation-based treatments. In this large, international series, EEA proved a safe and effective intervention that was generalizable across centers in the United States and Europe. Severe complications were rare, and significant improvements in headache and vision loss were noted in most patients.",

Ischemic isolated CNP share several atherosclerotic risk factors that are responsible for stroke which include hypertension, diabetes mellitus and dyslipidemia. Hyperhomocysteinemia is atherogenic and hence is also considered as an independent risk factor for stroke. So indirectly, elevated homocysteine in CNP may act as a risk factor for stroke. To determine the incidence of isolated ischemic CNP secondary to elevated serum homocysteine (predisposing them to a greater risk of stroke), and if serum homocysteine levels need to be checked routinely in all isolated CNP by neuro-ophthalmologists. This is a retrospective case study, in which 66 patients diagnosed with ischemic isolated CNP were enrolled. Informed written consent was obtained from all who participated in this study. Data of these patients were collected from the electronic medical records and were analyzed. Complete anterior, posterior segment and neuro-ophthalmic examinations were done, in addition to routine blood investigations and serum homocysteine. The mean age was 55 years old. Gender wise, 74.24% affected were males and 25.76% were females. The sixth nerve was affected in 68.18% cases. Of 66 patients, 37 cases (56.06%) had elevated serum homocysteine. In patients > 40 years and without any systemic risk factors, 63.2% had elevated serum homocysteine. In patients < 40 years and without systemic risk, 66.7% had high serum homocysteine levels. In cases without systemic risk factors, serum homocysteine may indirectly act as a risk factor for developing stroke in patients having isolated ischemic CNP. According to our study, patients with or without risk factors and those above 40 years, 56.06% patients with isolated ocular motor palsy had elevated serum homocysteine. This implies that the level of elevated serum homocysteine was statistically significant (P < 0.05) in these patients; thus, indirectly showing a greater predilection towards developing a stroke. In this small pilot study, we show that even in neuro-ophthalmology serum homocysteine should be routinely checked for all patients with isolated ischemic CNP. This might reduce the incidence of patients developing a stroke.",

Cranial nerve (CN) injuries accompanying TBI can severely impact patients' quality of life. This review aims to address the gap in research regarding the severity, mechanisms of injury, and associated intracranial injuries, emphasizing the importance of early detection and intervention. A comprehensive literature search was conducted across databases such as PubMed and Ovid using key terms, including \"cranial nerve injury,\" \"cranial nerve palsy,\" \"traumatic brain injury,\" and \"Glasgow Coma Scale.\" Inclusion criteria encompassed studies reporting CN injuries with TBI, categorized by Glasgow Coma Scale (GCS) scores, and the mechanisms of injury. A total of 14 studies were reviewed, integrating data from adult and pediatric populations. The incidence of CN injuries in TBI patients varies in the literature, with studies reporting rates between 5%-23%. Data revealed significant occurrences of CN injuries in mild (GCS scores 13-15), moderate (GCS scores 9-12), and severe (GCS scores < 9) TBI. Common mechanisms of injury included automobile accidents and falls; crush injuries were a notably common mechanism of injury in pediatric patients with TBI. Associated injuries included skull base fractures (38.9%), subdural hematomas (16.6%), epidural hematomas (18.9%), and subarachnoid hemorrhage (25.6%). Early detection and intervention were found to be critical in improving patient outcomes, with delays leading to increased disability and poor prognosis. The high prevalence of CN injuries in even mild cases of TBIs emphasizes the need for physicians to be equipped to assess, diagnose, and treat CN deficits in all forms of neurological trauma. By acknowledging common mechanisms of injury and associated intracranial injuries, we can elucidate the possibility of CN damage in order to facilitate early recognition and treatment. The identification of CN injury also suggests the importance of investigating other intracranial injuries such as skull base fractures, epidural or subdural hematomas, and hemorrhage.",

This study aimed to examine the relationships between oral health, disease severity and determinants of health in people living with amyotrophic lateral sclerosis (pALS), and to identify key predictors of oral hygiene outcomes. Individuals with ALS completed an oral hygiene and bulbar screening during their multidisciplinary appointment. Disease demographics, determinants of health, oral health outcomes and bulbar disease outcomes were collected. Descriptives and one sample t-tests were performed to compare oral hygiene outcomes with healthy reference values. Multiple regression analyses were conducted to assess the relationship between disease demographics and oral health. Sixty-two pALS aged 64.0 (+/- 10.8), 40% female, 31% Hispanic/Latino and 37% bulbar onset disease were enrolled.

This study assessed the feasibility, safety, and diagnostic performance of a surgeon-controlled, free-hand extraocular muscle electrode placement for corticobulbar motor evoked potentials (cb-MEPs) and direct nerve stimulation (DNS). This monocentric, observational, retrospective study enrolled 40 patients scheduled for skull base tumor surgery, with planned intraoperative monitoring of CN III and/or VI. Curved needle electrodes were placed free-hand by the neurosurgeon at the scleral\u2013muscular junction of the medial and/or lateral rectus, and cb-MEPs and DNS were recorded; evaluability required reproducible baselines. Primary endpoint was 3-month cranial nerve palsy. Diagnostic accuracy was calculated, and Spearman correlations tested the relationship between intraoperative percentage amplitude change and postoperative deficit severity. Placement succeeded in all cases (mean 10 min) with one transient conjunctivitis (2.5%). Stable baseline cb-MEPs occurred in 20/37 (CN III) and 18/31 (CN VI). For CN III, cb-MEPs showed sensitivity 66.7% and specificity 100%; amplitude reduction correlated with postoperative severity (\u03c1\u2009=\u20090.94, p\u2009<\u20090.001).

The clinical manifestations are heterogeneous, ranging from slowly progressive pure cerebellar ataxia to complex phenotypes with sensory or extrapyramidal involvement. To the best of our knowledge, the present report is the first to describe a Han Chinese family carrying the PRKCG c.424T>G (p.C142G) mutation, which has previously only been described in Danish and Japanese cohorts. The proband, a 72-year-old man, developed gait instability in his 40s, progressing to dysarthria, intention tremor, oculomotor slowing and sensory impairment. Brain MRI revealed severe diffuse cerebellar atrophy. The siblings and daughter of the patient presented with variable ataxic symptoms, confirming autosomal dominant inheritance. Genetic testing by next-generation sequencing identified the heterozygous c.424T>G mutation, co-segregating in affected family members. This mutation localizes to the C1 regulatory domain of PKC\u03b3, a zinc-finger structure critical for diacylglycerol binding and kinase autoinhibition. Substitution of cysteine by glycine at codon 142 destabilizes zinc coordination, impairs protein stability and disrupts membrane recruitment. Functional evidence suggests that C142G induces aberrant kinase activity, misfolding and altered MAPK signaling, resulting in chronic cellular stress without rapid neuronal death, thus accounting for the indolent course of the disease compared with that of polyglutamine SCAs. The present findings expand the knowledge regarding the ethnic and geographic distribution of the codon 142 mutation and highlight the complexity of genotype-phenotype associations, as clinical presentations varied from mild gait ataxia to cognitive impairment and bulbar involvement. The report underscores the value of early genetic testing in unexplained ataxia, facilitating accurate diagnosis, genetic counseling and individualized management. Further functional studies are warranted to clarify the pathogenic mechanisms and to explore potential targeted therapies for SCA14.",

A retrospective analysis was conducted at two tertiary hospitals, categorizing patients into COVID-GBS (case group) and Non-COVID-GBS (control group). During the Omicron wave, the number of GBS hospitalizations was 1.5 times higher compared to the period of 2018-2019 (99 cases vs. 66 cases). Poisson regression analysis confirmed a significant increase in GBS incidence during the Omicron wave (December 2022-February 2023) compared to the 2018-2019 baseline period, with an IRR of 1.541 (95% CI: 1.123-2.129, p\u2009=\u20090.0079). COVID-19-associated GBS patients were significantly older (54.04 vs. 42.06 years, p\u2009=\u20090.002) and exhibited higher rates of cranial nerve involvement (p\u2009=\u20090.014), particularly bulbar involvement (p\u2009=\u20090.009). Acute severity was greater in COVID-19-associated cases, evidenced by elevated ICU admissions, higher peak GBS disability scores (p\u2009=\u20090.048), increased mechanical ventilation needs, and one fatality. The median latency from COVID-19 infection to neurological onset was 9.5 days (IQR: 8-14). Despite these acute differences, 6-month disability outcomes showed no significant divergence between groups, suggesting similar long-term prognoses. The surge in GBS incidence aligns with broader reports of elevated GBS rates during COVID-19 surges, though mechanistic links may involve immune-mediated pathways rather than direct viral causation.",

This study aimed to develop and validate a simple, smartphone-based task for the objective assessment of tongue movements and to examine their association with clinical variables. 37 ALS patients and 20 age- and sex-matched controls performed a tongue lateralization task, recorded with a smartphone. A deep-learning U-Net++-based model was used for segmentation and feature extraction. The frequency and maximum amplitude of tongue movements were quantified. Clinical measures included the ALS Functional Rating Scale-revised (ALSFRS-r) bulbar sub-scores, tongue fasciculations, jaw jerk, and tongue \"spasticity\". Between-group differences and associations between tongue metrics and clinical features were assessed. The U-Net++-based model achieved robust segmentation performance. Patients showed lower tongue movement frequency than controls (0.14 vs. 0.40, t = -9.58, p < 0.001). Normalized frequency was associated with dysarthria (t = -3.13, p = 0.003) but not dysphagia (t = -1.05, p = 0.30). Normalized frequency (t = 2.77, p = 0.009) and tongue \"spasticity\" (t = -2.57, p = 0.015) were both associated with speech performance in a multiple-regression model (R = 0.51, adjusted R2 = 0.43). Our method provides an objective, minimally invasive measure of bulbar function in ALS, which correlates with clinical ratings and may detect subtle impairments not captured by standard assessments. This approach offers a promising tool for remote monitoring and may support more effective disease management.",

PrimeC is a fixed-dose oral combination of celecoxib and ciprofloxacin designed to target ALS-related mechanisms, including neuroinflammation, iron homeostasis, and dysregulated microRNAs. To evaluate the safety, tolerability, and potential efficacy of PrimeC in people living with ALS. This was a randomized, double-blind, placebo-controlled, phase 2b trial conducted at 4 ALS referral centers from May 2022 to November 2023 and followed by 12-month open-label extension. Adults with definite or probable ALS and disease duration of 30 months or less were eligible. Of 73 screened, 69 were randomized and 68 were included in the intent-to-treat population. Participants were randomized 2:1 to receive PrimeC or placebo for 6 months, followed by open-label extension PrimeC for all. The primary outcome was safety and tolerability. The prespecified primary biomarker outcome was plasma neuron-derived-exosomal TAR DNA-binding protein 43 (TDP-43) or prostaglandinJ2. Secondary outcomes included change in ALS Functional Rating Scale-Revised (ALSFRS-R) score at 6 and 18 months, survival, and time-to-composite events. Exploratory biomarkers included neurofilament light chains, iron-regulatory proteins, and circulating microRNAs. The 68 participants were well balanced in age at entry and sex. In the PrimeC group, the mean (SD) age was 59.1 (9.1) years, and 27 of 45 participants were male. In the placebo group, the mean (SD) age was 55.0 (13.0) years, and 14 of 23 participants were male. PrimeC was well tolerated, with a safety profile comparable to placebo (adverse event rate, 66.7% PrimeC vs 65.2% placebo). Drug-related adverse events were more frequent with PrimeC (20.0% vs 4.3%), mostly mild to moderate, and transient. At month 6, the mean ALSFRS-R difference was 2.23 points between PrimeC and placebo (95% CI, -0.61 to 5.07; P\u2009=\u2009.12). At month 18, ALSFRS-R scores in participants continuously treated with PrimeC maintained a difference (7.92 points; 95% CI, 2.25 to 13.60; P\u2009=\u2009.007), with significant bulbar difference (3.18 points; 95% CI, 1.32 to 5.04; P\u2009=\u2009.001). Continuous treatment was associated with lower risk of ALS complications, including hospitalization, respiratory failure, or death (HR, 0.36; 95% CI, 0.15-0.85; P\u2009=\u2009.02). In the double-blind period, transferrin levels were preserved with PrimeC (1.90 \u03bcmol/L difference; P\u2009=\u2009.03), the negative ferritin-ALSFRS-R correlation observed in placebo (\u03c1\u2009=\u2009-0.50; P\u2009=\u2009.02) was abolished, and ALS-associated microRNAs were downregulated (log2 fold change: miR-199a-3p, -1.87; false discovery rate [FDR] P\u2009=\u2009.004; miR-199a-5p, -2.23; FDR P\u2009<\u2009.001; miR-181a-5p: -1.89; FDR P\u2009=\u2009.001; miR-181b-5p, -1.62; FDR P\u2009=\u2009.005). Prespecified neuron-derived exosome TDP-43/PgJ2 analyses will be reported separately following completion of development and analyses. PrimeC was safe and well tolerated over 18 months.

Diagnosis may be delayed because early neurological symptoms overlap with common pregnancy-related complaints. Although case reports describe variable maternal severity and neonatal outcomes, evidence is fragmented, and no prior systematic review has synthesized these data. To systematically review published case reports and series of Guillain-Barr\u00e9 syndrome (GBS) with onset during pregnancy, focusing on maternal disease course, obstetric management, and neonatal outcomes. A systematic revie w was conducted according to PRISMA 2020 guidelines and registered in PROSPERO (CRD420251127698). PubMed, Embase, and Scopus were searched to August 2025 for case reports and series of pregnancy-onset GBS. Eligible studies required a confirmed diagnosis and at least 1 maternal, obstetric, or neonatal outcome. A total of 90 studies comprising 101 cases were included. Mean maternal age was 27.3 years, with symptom onset most frequent in the third trimester (52.5%). Preceding infection was reported in nearly half. Limb weakness (98%) and areflexia (87.6%) were predominant, and acute inflammatory demyelinating polyneuropathy accounted for 70% of subtypes. ICU admission occurred in 64%, and mechanical ventilation in 45%. Bulbar weakness (OR 5.29, P=.001) and autonomic dysfunction (OR 7.17, P<.001) were strongly predictive of ICU requirement. Neurological recovery was complete in 35%, partial in 59.4%, with maternal mortality of 5.2%. Obstetric outcomes showed cesarean delivery in 54.8% and preterm birth in 36%. One-third of neonates were low birthweight, though overall survival was 85.6%. Third-trimester onset correlated with higher risks of preterm delivery and maternal respiratory compromise, underscoring the vulnerability of late gestation. GBS in pregnancy carries substantial maternal morbidity and obstetric risk. Early recognition and multidisciplinary care are crucial. Despite high neonatal survival, risks of preterm birth and maternal ventilation remain significant.",

Standardization of CSMW resection has improved the safety and reproducibility of this maneuver and may increase the extent of resection. We evaluated surgical outcomes after CSMW resection in invasive pituitary adenomas, with special emphasis on growth hormone (GH)-secreting adenomas. We retrospectively reviewed patients with invasive pituitary adenomas who underwent CSMW resection at 2 high-volume neurosurgical centers between 2021 and 2023. Preoperative imaging, tumor invasiveness, hormonal secretion, extent of resection, biochemical remission, and complications were assessed. A surgical management algorithm for the CSMW is also presented. A total of 193 pituitary adenomas were operated on during the study period. CSMW resection was performed in 63 patients (33%), including 28 nonfunctioning adenomas (44%) and 35 functioning adenomas (56%). The most frequent functioning subtype was GH-secreting adenoma (n = 20), followed by ACTH-secreting adenoma (n = 8) and prolactin-secreting adenoma (n = 4); 3 tumors showed GH/prolactin co-secretion. Cavernous sinus invasion was classified as group A (Knosp 0-3A) in 40 patients (64%), group B (Knosp 3B) in 11 (17%), and group C (Knosp 4) in 12 (19%). Gross total resection was achieved in 34 group A tumors (85%), 4 group B tumors (36%), and no group C tumors. In acromegaly, biochemical remission after surgery was achieved in 13 of 14 group A tumors (93%), 2 of 5 group B tumors (40%), and 0 of 1 group C tumors. Histologic invasion of the medial wall was confirmed in 55 of 63 specimens (87%) and in 32 of 40 group A tumors (80%). There were no deaths or internal carotid artery injuries. Two patients (3%) developed a new transient cranial nerve palsy, and 1 patient (1.6%) had a postoperative cerebrospinal fluid leak. Endoscopic endonasal CSMW resection is safe and technically feasible in experienced hands. In selected invasive pituitary adenomas, particularly functioning tumors with Knosp 0-3A invasion, it may improve extent of resection and biochemical remission.",

With rare reports of diplopia, diagnosis depends on indirect signs such as abnormal head posture, strabismus, or abnormal gaze. The oculomotor (III), trochlear (IV), and abducens (VI) nerves follow sometimes long, intricate courses from the brainstem to the target muscle(s) within the orbit. Accurate diagnosis requires integrating anatomic understanding with subtle clinical presentations and imaging findings, and management must emphasize limitations of congenital disease while relying on neural plasticity and adaptive behaviors.

Patients with a confirmed diagnosis of ALSs were included, and sociodemographic and clinical data were collected.The sample was composed of 89 ALS patients, with a slight female predominance (53%) and a high frequency of fALS8 cases (45%). The fALS8 patients were diagnosed at a younger age, at approximately 50 years, compared to 53 years among the sALS patients (p\u2009=\u20090.043). Lower limb onset predominated in the fALS8 group (87%), while the sALS group showed more heterogeneous presentations, including bulbar onset (14%). The time until the diagnosis was significantly longer in the fALS8 group compared to the sALS group, both from symptom onset (approximately 51 versus 30 months respectively; p\u2009<\u20090.001) and after admission to a specialized center (7 versus 4 months respectively; p\u2009=\u20090.002). Dysphagia and gastrostomy were more frequent in the sALS group compared to the fALS8 group (p\u2009=\u20090.02 and p\u2009<\u20090.01 respectively), and older age at diagnosis was associated with worse functional scores.The fALS8 group presented with distinct clinical and demographic features compared to the sALS group, including younger age at diagnosis, more homogeneous symptom onset, and lower frequency of dysphagia and need for gastrostomy. The diagnosis was more delayed in the fALS8 group, and older age at diagnosis was associated with worse functional status.

While the MND/ALS literature is dominated by innovative brain studies, motor disability in ALS is primarily driven by neurogenic muscle change impacting mobility, dexterity, respiratory and bulbar function. With the intention of raising awareness of muscle-derived imaging markers in ALS, a systematic review has been conducted. Study designs, imaging methods, data interpretation frameworks, and cohort characteristics were systematically evaluated to identify innovative approaches and barriers to clinical implementation. A total of 219 studies were screened and 73 original studies selected for systematic review; 37 muscle MRI studies and 36 studies using ultrasound, PET or CT. All of the selected studies successfully captured ALS-associated muscle degeneration and their methods included the evaluation of muscle dimensions (thickness/volumes n\u2009=\u200934), 'acute' denervation (water content, n\u2009=\u200915), fasciculation counts (n\u2009=\u200914), 'chronic' neurogenic change (fat content, n\u2009=\u200921), metabolic changes (n\u2009=\u20094), diffusion alterations (n\u2009=\u20098) and echo intensity changes (n\u2009=\u200913). Despite the huge impact of lower motor neuron dysfunction on the patients' independence, survival and quality of life, muscle imaging is a glaringly overlooked frontier of MND/ALS research. This is a missed opportunity, as a variety of non-invasive quantitative muscle imaging techniques have been successfully used in other neurological conditions; these protocols are easy to implement on commercial MRI and ultrasound platforms and recent studies have demonstrated their ease of use and potential clinical utility.",
        "41892827": "ID: 41892827\nTitle: Biomechanical Voice Parameters as Potential Biomarkers for Phenotype Differentiation in Amyotrophic Lateral Sclerosis: A Cross-Sectional Study.\nAbstract: Background/Objectives: Amyotrophic lateral sclerosis (ALS) is a clinically heterogeneous neurodegenerative disease in which bulbar involvement frequently affects speech and voice production. Although acoustic voice analysis can detect phonatory alterations in ALS, its ability to differentiate clinical phenotypes remains limited. This study investigated whether biomechanical voice parameters provide complementary information for characterizing bulbar involvement across bulbar-onset ALS (ALS-B) and spinal-onset ALS (ALS-S) and explored their association with clinical and functional measures. Methods: This cross-sectional observational study included 50 patients with ALS (20 ALS-B, 30 ALS-S) and 50 controls with non-neurological voice disorders. Sustained vowel phonation was analyzed using acoustic measures and biomechanical voice parameters derived from a standardized model of vocal fold vibration. Perceptual voice severity was assessed using the GRBAS scale, while functional status was evaluated with the ALS Functional Rating Scale-Revised (ALSFRS-R) and the Barthel Index. Associations with clinical measures were explored in secondary analyses. Results: Compared with controls, ALS patients showed significant differences in acoustic measures and several biomechanical parameters related to glottal closure and vibratory stability. Biomechanical analysis revealed significant differences between ALS-B and ALS-S, particularly in parameters reflecting vibratory asymmetry, glottal tension and cycle-to-cycle instability. Unexpectedly, ALS-B showed greater perceptual voice severity and higher Barthel Index scores than ALS-S, while no differences were observed in global ALSFRS-R total scores. Conclusions: Biomechanical voice analysis appears to capture physiologically meaningful alterations in vocal fold function in ALS and provides complementary information for characterizing bulbar motor involvement across clinical phenotypes, particularly ALS-B disease. When combined with acoustic and clinical assessments, this approach may enhance the evaluation of bulbar involvement and functional status in ALS.",

This was associated with heat intolerance, palpitations, diarrhea, proximal weakness, and weight loss.A video fluoroscopy study confirmed moderate oropharyngeal dysphagia. Evaluation was done to exclude other causes including mechanical compression, neuromuscular causes, and malignancy.The patient's dysphagia improved with carbimazole doses of up to 30 mg twice daily, and propranolol doses of up to 20 mg 3 times daily, titrated as thyrotoxicosis improved. He became euthyroid after 5 weeks of treatment, and had clinical improvement in swallowing by 8.5 weeks, improving from requiring nasogastric tube feeding to tolerating regular diet and thin fluids.

Lyme neuroborreliosis occurs in up to 15% of untreated Lyme disease cases and most commonly presents with painful radiculitis, cranial nerve palsy, and meningitis; progression to encephalitis occurs in approximately 3.3% to 9% of cases. Lyme neuroborreliosis can develop despite appropriate antibiotic therapy of early Lyme disease. Diagnosis of Lyme neuroborreliosis is based on a combination of compatible neurological symptoms, serologic evidence of Lyme disease, and cerebrospinal fluid (CSF) abnormalities, which can include measurement of a Bb CSF: serum antibody index. CASE REPORT We describe an 84-year-old man who developed acute encephalopathy after removal of a dead tick from under his right eyelid. Initial symptoms included periorbital swelling and right-sided facial nerve palsy. Early treatment with doxycycline was completed. His illness subsequently progressed to encephalopathy, characterized by agitation, hallucinations, and ataxia. Diagnostic evaluation revealed CSF lymphocytic pleocytosis, positive Lyme serologies, and cranial nerve enhancement on magnetic resonance imaging. The patient improved following treatment with ceftriaxone followed by a 21-day course of doxycycline, and received a diagnosis of probable Lyme neuroborreliosis. Anti-GFAP-1 antibodies were detected in CSF, but were believed to be non-contributory given clinical recovery in the absence of immunomodulatory therapy. CONCLUSIONS This case highlights a rare presentation of probable Lyme neuroborreliosis complicated by acute encephalitis despite early doxycycline treatment. The need for specific CSF testing is underscored along with the difficulties in diagnosis even with ideal testing.",

The infantile form, presenting before 2 years of age, is the most rapidly progressive and is associated with a high risk of early mortality. We describe the clinical outcomes of early nucleoside therapy in a series of children with infantile-onset TK2 deficiency. We retrospectively reviewed four children with genetically confirmed infantile-onset TK2 deficiency treated with oral deoxycytidine/deoxythymidine (dC/dT) through an Early Access Program at two centers. Dosing was escalated to 800\u2005mg/kg/day as tolerated. Patients were followed at baseline, Month 1, and regular intervals thereafter. Outcomes included neurological examinations, eight motor milestones, and respiratory and feeding support. Safety laboratory results, neuroimaging, and biopsy findings were reviewed. Treatment began at 19-24 months (median duration 26 months; range: 4-81). All presented within the first year with hypotonia, motor regression, and respiratory and/or bulbar involvement. Two required invasive ventilation and three required tube feeding before therapy. After dC/dT initiation, all improved with no further milestone loss. Three achieved independent ambulation and stair climbing; the fourth, at 4 months of therapy, has begun unassisted walking. Both tracheostomized patients were weaned from ventilation, and enteral feeding was discontinued in all three within 1-6 months. Only mild dose-related diarrhea occurred in one patient.

Thirteen patients diagnosed with ALS according to the Gold Coast criteria were enrolled to be examined at two time points (T1 and T2), with a one-year interval. The ALS Functional Rating Scale-Revised (ALS-FRS-R), the Nordic Orofacial Test Screening (NOT-S), the Decayed Missing and Filled Teeth (DMFT) index, Plaque Index, and standard orthodontic assessments were used to quantify changes in disease progression, orofacial function, dental health, and occlusal parameters, respectively. Statistical evaluation: Paired sample t-tests were performed to evaluate differences between T1 and T2 for continuous variables. Chi-square and Fisher's exact tests were used for categorical data. Multiple linear regression analyses were carried out to assess potential associations between general disease progression, ALS type, and orofacial functional or dental health decline. A significance level of p < 0.05 was adopted for all analyses. Thirteen patients were examined at T1, 10 of whom completed both evaluations. A significant deterioration in the general disease condition was observed (ALS-FRS-R: mean difference -6.0 \u00b1 6.98; p = 0.024). Orofacial function worsened significantly as reflected by an increase in NOT-S total score (+2.3; p = 0.001). Dental health also declined, with a significant increase in DMFT (+1.8; p = 0.014) and Plaque Index (+0.4; p = 0.004). However, occlusal parameters remained stable over the 12-month period, with no significant changes in overjet (p = 0.860) or overbite (p = 0.347). The bulbar type of ALS seems to show worse deterioration of orofacial function over time, and individuals with more significant general disease progression also showed worse orofacial functional decline. ALS has a significant impact on orofacial function and dental health, characterized by neuromuscular deterioration, increased plaque accumulation, and a higher number of affected teeth. Despite this decline, dental occlusion appears to remain stable in the short term. These findings highlight the need for interdisciplinary and preventive oral care strategies in the management of patients with ALS, aiming to preserve oral function and quality of life in a progressively disabling disease.",

Early recognition is critical in endemic settings such as India. A previously healthy female in late adolescence presented with a one-month history of headache followed by progressive left-sided weakness and multiple cranial nerve deficits, producing a crossed brainstem syndrome. Magnetic resonance imaging (MRI) of the brain revealed conglomerated ring-enhancing lesions in the midbrain and pons, accompanied by surrounding edema. Magnetic resonance spectroscopy (MRS) demonstrated a lipid-lactate peak. Cerebrospinal fluid (CSF) analysis and systemic laboratory investigations were within normal limits. Empirical anti-tubercular therapy (ATT) with adjunctive corticosteroids was initiated, with clinical improvement noted within two weeks and continued gains on follow-up. Brainstem tuberculoma can closely mimic brainstem stroke and other mass lesions. In endemic regions, characteristic MRI/MRS findings should prompt consideration of tuberculoma even when CSF findings are normal. Early treatment may prevent the need for invasive diagnostic procedures and improve outcomes. Brainstem tuberculoma should be considered an important differential diagnosis in young patients presenting with crossed brainstem signs in TB-endemic regions. A combination of characteristic imaging findings and high clinical suspicion can support the early initiation of ATT with adjunctive corticosteroids, which, in this case, was associated with prompt and favorable neurological recovery.",

Methods: We report the case of a 32-year-old woman at 31 weeks of gestation who presented with severe headache and left third cranial nerve palsy. Imaging revealed diffuse SAH with significant obstructive hydrocephalus and a 5 mm left posterior communicating artery aneurysm. Following multidisciplinary discussion, surgical clipping was performed while preserving the pregnancy to allow for fetal lung maturation. On postoperative day 8, the patient developed right-sided weakness and aphasia secondary to severe vasospasm. Initial management with catecholamine-induced hypertension resulted in increased uterine contractions and fetal distress. Subsequent intra-arterial administration of nimodipine effectively resolved the vasospasm, enabling cessation of vasopressor therapy. After achieving fetal lung maturity, cesarean section was performed at 34 weeks, followed by ventriculo-peritoneal shunt placement for communicating hydrocephalus. Due to sustained shunt failure, the distal catheter was finally inserted into the superior vena cava at the junction of the atrium. Results: The patient showed gradual neurological recovery with complete resolution of third cranial nerve palsy, and both mother and infant were discharged without complications. Conclusions: This case highlights that while standard vasospasm therapies can be implemented during pregnancy, hemodynamic approaches may provoke maternal and fetal complications. Endovascular rescue strategies should be promptly considered for severe vasospasm, and ventriculo-atrial shunting for complex communicating hydrocephalus may serve as a viable alternative option in post-cesarean patients.",

Fifty-four participants with ALS were enrolled and participated in an 8-week pretreatment run-in, followed by three 8-week dosing periods and an 8-week follow-up. They completed a speech assessment every two weeks in the clinic or at home. We observed moderate to high correlations between digital measures of speech timing and articulatory motor function, and the ALS Functional Rating Scale-Revised, slow vital capacity and plasma neurofilament light chain. Furthermore, speech measures can show functional decline before the ALSFRS-R does, while also capturing differences between participants with bulbar symptoms and those without. The results support the feasibility and utility of digital speech endpoints to study disease impact in ALS clinical trials.",

The most common genetic cause of ALS is the hexanucleotide repeat expansion in the C9orf72 gene, which is associated with earlier disease onset, faster progression, and an increased frequency of cognitive and psychiatric involvement. Data on population-specific characteristics of C9orf72-associated ALS remains limited in Central and Eastern Europe. Between 2011 and 2024, a total of 959 ALS patients fulfilling established diagnostic criteria were screened for C9orf72 repeat expansions at two Hungarian centers. Hexanucleotide repeat expansions were analyzed using repeat-primed long-read PCR. Repeat numbers exceeding 30 were considered pathogenic. Clinical, demographic, and disease course data were retrospectively collected and analyzed. Pathogenic C9orf72 repeat expansions were identified in 63 of 959 patients, corresponding to a prevalence of 6.57% among Hungarian ALS patients. Bulbar onset was the most common presentation and was associated with faster progression and shorter survival (mean survival: 27.8\u00a0months). Cognitive impairment and psychiatric comorbidities were present in a substantial proportion of patients and were associated with slower functional decline. Regional differences in survival were observed, likely reflecting disparities in healthcare access rather than biological factors. This study provides the first comprehensive national characterization of C9orf72 repeat expansion-associated ALS in Hungary, based on a genetically defined cohort assembled over 13\u00a0years. Despite limitations related to retrospective data collection and cohort size, this ethnically homogeneous dataset offers valuable insight into population-specific clinical and epidemiological features and complements larger international studies. Systematic characterization and longitudinal follow-up of genetically defined, trial-ready ALS cohorts will be essential as targeted therapies for C9orf72-associated ALS approach clinical implementation.",

Conventional management remains conservative, often yielding unsatisfactory outcomes. We report the case of a 13-year-old girl who developed complete right third cranial nerve palsy following a 15-meter fall, presenting with exotropia (35\u0394), ptosis, complete ophthalmoplegia, and pupillary dysfunction. Brain CT revealed hemorrhage in the right cavernous sinus, and subsequent MRI demonstrated focal nerve damage. Thirty-eight days post-injury, a single botulinum toxin type A (BTX-A) injection (5 units) was administered to the right lateral rectus muscle. Progressive improvement in ocular alignment and motility was observed, with resolution of diplopia by 4.5 months and sustained orthotropia at 10 months post-injury. Although pupillary dilation persisted, functional recovery was substantial. This case demonstrates that early BTX-A intervention may prevent lateral rectus contracture and promote functional recovery in traumatic third cranial nerve palsy. BTX-A represents a promising minimally invasive therapeutic option that warrants further investigation in larger patient populations.",
        "41994724": "ID: 41994724\nTitle: Clinical Profile of Patients With Isolated Lateral Rectus Palsy in Adults.\nAbstract: Background Isolated lateral rectus (LR) palsy is a common cranial nerve palsy with a variety of causes. Horizontal diplopia is frequently caused by isolated LR palsy, a common cranial nerve palsy in adults. The abducens nerve is vulnerable to a variety of vascular, inflammatory, traumatic, viral, and compressive diseases because of its lengthy intracranial journey. This study aims to describe the clinical profile, etiological distribution, and outcomes in adults with isolated LR palsy. Methodology This retrospective observational study included 29 consecutive adults diagnosed with isolated LR palsy. Demographic characteristics, clinical presentation, investigation findings, etiological diagnoses, and recovery outcomes during follow-up were systematically recorded and analyzed using descriptive statistical methods. Results The mean age was 48.17 years (range = 19-85 years), with a male-to-female ratio of 15:14. Etiologies included diabetes-related microvascular ischemia in seven (24.1%) patients, hypertension-related microvascular ischemia in seven (24.1%) patients, infection with inflammation in four (13.8%) patients, trauma in four (13.8%) patients, idiopathic causes in two (6.9%) patients, tumor in one (3.4%) patient, cavernous sinus thrombosis in three (10.3%) patients, and microvascular ischemia associated with both diabetes mellitus and hypertension in one (3.4%) patient. At the last follow-up, 19 (65.5%)\u00a0patients had complete recovery, two (6.8%) had partial recovery, one (3.4%) had no recovery, and seven (24.1%) were lost to follow-up. Conclusions Microvascular ischemia associated with diabetes mellitus and hypertension was the leading cause of isolated LR palsy in adults. Most patients demonstrated improvement during follow-up, whereas traumatic and compressive etiologies showed relatively poorer outcomes. Careful systemic evaluation and targeted neuroimaging are important in patients with atypical presentations or suspected non-microvascular causes. These findings emphasize the importance of systematic clinical assessment, etiological evaluation, and follow-up in adults presenting with isolated LR palsy.",

In CARTITUDE-1 and CARTITUDE-4, rates of all-grade parkinsonism were 6% and\u2009<\u20091%, respectively, while rates of cranial nerve palsy were 3% and 9%, respectively. This study aimed to characterize new-onset nonimmune effector cell-associated neurotoxicity syndrome (non-ICANS) neurologic events (NEs) among patients with RRMM receiving cilta-cel after 1-3 or\u2009\u2265 4 prior LOT. This retrospective study used two real-world data sources: open and closed insurance claims from the Komodo Research Database (February 2021-November 2024), and electronic medical records from Loopback Analytics (February 2021-December 2024). New-onset non-ICANS NEs, including parkinsonism, cranial nerve palsy, and Guillain-Barr\u00e9 syndrome, were assessed from cilta-cel infusion until the end of clinical activity, death, or end of data availability. Analyses were conducted separately by database and stratified by LOT. In patients with 1-3 prior LOT (Komodo: 124; Loopback: 79), over a median follow-up of 3.4-3.5\u00a0months, cranial nerve palsy occurred in 5.6% and 5.1% in Komodo and Loopback, respectively, with no parkinsonism or Guillain-Barr\u00e9 syndrome observed. In patients with\u2009\u2265 4 prior LOT (Komodo: 524; Loopback: 191), over a median follow-up of 13.2-13.3\u00a0months, parkinsonism occurred in 1.0% in both databases, cranial nerve palsy in 4.6% and 1.0%, and Guillain-Barr\u00e9 syndrome in 0.2% and 0.5% in Komodo and Loopback, respectively. In this real-world study, rates of non-ICANS NEs post-cilta-cel infusion across two databases were comparable to or lower than prior trials or real-world studies, reinforcing the favorable risk-benefit profile of cilta-cel in routine practice.

METHODS: A total of 66 and 117 patients within 2 weeks of symptom onset were enrolled in the inflammation and ischemic groups. Twenty-two potential predictors were evaluated; predictors that remained significant after Benjamini-Hochberg adjustment (false discovery rate 0.05) were entered into a multivariable logistic regression model. Discrimination was assessed by the area under the receiver operating characteristic curve (AUC), and calibration by the Hosmer -Lemeshow goodness-of-fit test. RESULTS: Significant predictors included vascular risk factor scores (VRFs), ocular motor nerve palsy scale (OMNPS) score, aggregate index of systemic inflammation (AISI), history of diabetes, and cavernous sinus thickness. The AUC was 0.899 (95% confidence interval, 0.838 to 0.939). At the optimal probability cutoff(0.674), sensitivity and specificity were 72.3% and 89.7%, respectively. The Hosmer-Lemeshow test yielded \u03c72\u2009=\u20094.262, P\u2009=\u20090.833. CONCLUSIONS: The logistic regression\u2013based model showed good discrimination and calibration for differentiating cavernous sinus inflammation from microvascular ischemic ocular motor CN palsy during early presentation, and may assist early clinical decision-making.",

We report a case of an elderly patient with late-onset, acetylcholine receptor (AChR) antibody-positive generalized myasthenia gravis who initially presented with ptosis, followed by progressive dysphagia and dysarthria, and subsequently developed head drop. Electromyography (EMG) confirmed a neuromuscular junction disorder, and serology demonstrated markedly elevated AChR antibodies. Early initiation of pyridostigmine and corticosteroids led to rapid clinical improvement, with the Myasthenia Gravis Activities of Daily Living (MG-ADL) score decreasing from 11/24 to 0/24 within three weeks. This case highlights the importance of considering MG in elderly patients presenting with isolated bulbar symptoms and demonstrates the diagnostic value of electrophysiology and antibody testing for timely treatment.",

We conducted a retrospective cohort study of adults (\u226518\u00a0years) diagnosed with ALS and included in the PRO-ACT database. Statin exposure was defined as any statin use at cohort entry. Statin users were matched 1:1 to non-users using propensity score matching based on age, baseline ALS Functional Rating Scale (ALSFRS), disease duration, ethnicity, bulbar onset, riluzole use, and cardiovascular or metabolic comorbidities. Participants were followed from cohort entry or statin initiation until death, end of follow-up (36\u00a0months), or loss to follow-up. The primary outcome was all-cause mortality at three years. The secondary outcome was disease progression, defined as time to a four-point decline in ALSFRS score. Cox proportional hazards models were used to estimate hazard ratios (HRs). Among 3439 eligible participants, 131 statin users (mean age 63.1\u00a0years; 34% female) were identified and matched to 131 non-users. Statin use was not associated with all-cause mortality at three years (HR 0.97; 95% CI 0.66-1.44; P\u00a0=\u00a00.89). Disease progression was also similar between statin users and non-users (HR 1.02; 95% CI 0.80-1.31; P\u00a0=\u00a00.90). In this large observational cohort, statin use was not associated with survival or disease progression in ALS. These findings do not support statin initiation or discontinuation based solely on ALS diagnosis or disease course.",

This also aims to analyze the association between readily available clinical predictors and pulmonary function. This retrospective study assessed 142 ALS patients treated at the First Hospital of Shanxi Medical University from August 2020 to June 2023. ALS was diagnosed based on revised El Escorial criteria with Awaji modifications. Clinical data and pulmonary function tests (PFTs) were performed during a single hospital stay. Respiratory insufficiency was marked as forced vital capacity (FVC) < 80% of predicted. Muscle strength of neck and limbs was measured with the Medical Research Council (MRC) scale. Multivariable logistic regression evaluated independent predictors of respiratory insufficiency. A nomogram was created and internally validated using bootstrap resampling (1,000 iterations). Model performance was assessed with ROC curve analysis, calibration curve analysis, and decision curve analysis (DCA). Of the 142 patients, 30 (21.1%) presented with baseline respiratory insufficiency. In the multivariable analysis, neck flexor muscle strength (OR = 0.497, 95% CI: 0.321-0.769; p\u2009=\u20090.002) and bulbar onset (OR = 4.392, 95% CI: 1.674-11.521; p\u2009=\u20090.003) were independent predictors in the multivariable analysis. The nomogram showed good discrimination and calibration (AUC = 0.823, 95% CI: 0.739-0.907). Weakness of neck flexors and bulbar onset are independently associated with baseline respiratory insufficiency in ALS patients. The proposed nomogram may serve as a useful tool for baseline screening and risk stratification. External validation in larger multicenter cohorts is warranted before clinical application.",
        "42032505": "ID: 42032505\nTitle: Posterior fossa hematoma: CT perfusion as a tool to reveal occult intracranial hypertension and support surgical decision-making - a case report.\nAbstract: BACKGROUND: Spontaneous posterior fossa hematoma is a neurological emergency associated with rapid deterioration from brainstem compression and localized intracranial hypertension. The resulting mass effect can reduce regional perfusion, but these changes are often not fully appreciable on non-contrast CT, and MRI is not always feasible in unstable patients. Invasive intracranial pressure (ICP) monitoring in the posterior fossa could provide direct information on compartmental pressure; however, catheter placement is technically challenging and carries risks including cerebellar hemorrhage, cerebrospinal fluid (CSF) leak, cranial nerve palsy, and brainstem contusion. Consequently, infratentorial ICP monitoring is rarely used, and treatment decisions are based on clinical examination, supratentorial ICP values, and conventional imaging, which may underestimate pressure effects. CT perfusion (CTP) offers a rapid, noninvasive method to assess regional perfusion, detect indirect signatures of occult intracranial hypertension, and identify cerebellar tissue at risk of reversible ischemia. CASE PRESENTATION: A 50-year-old woman with arterial hypertension was found comatose with a Glasgow Coma Scale (GCS) score of 3, mid-mydriatic non-reactive pupils, and absent airway protective reflexes. Non-contrast CT revealed a large right cerebellar hematoma. CT perfusion demonstrated hypoperfusion at the hematoma site, with prolonged time-to-maximum (TMAX) in the surrounding cerebellar parenchyma and reduced cerebral blood flow (CBF) despite preserved cerebral blood volume (CBV), suggesting salvageable tissue. In the absence of large-vessel stenosis, prolonged TMAX was interpreted as most consistent with reduced effective cerebral perfusion pressure, plausibly related to compartmental intracranial hypertension in the posterior fossa. Prolonged TMAX with low CBV was also observed in the ipsilateral cerebral peduncle, indicating localized ischemia likely related to upward transtentorial herniation. The patient underwent emergency external ventricular drain placement and posterior fossa decompression with hematoma evacuation. Follow-up CTP on postoperative day seven showed normalization of perfusion parameters, with improved CBV and CBF and reduced TMAX. CONCLUSIONS: This case illustrates how CTP can complement conventional imaging in posterior fossa hematomas by providing physiological information that is otherwise difficult to obtain invasively. By revealing perfusion patterns consistent with occult compartmental intracranial hypertension and demonstrating viable tissue at risk, CTP may counterbalance prognostic nihilism and support timely surgical decision-making in patients with posterior fossa hematoma.",

A clinically grounded sEMG framework was developed, integrating a standardized, repeatable protocol with a novel analytic pipeline, to automatically extract 60 features from six craniofacial muscle groups during a set of motorically demanding but cognitively and linguistically less challenging oral diadochokinetic (DDK) tasks. Using this framework, 104 oral DDK recordings were acquired from 16 individuals with ALS-nine with overt bulbar symptoms (ALS+B) and seven without (ALS-B)-and 10 healthy controls (HCs). The sEMG features were clustered into 10 interpretable composite measures and validated by evaluating their (1) internal consistency using Cronbach's \u03b1 ; (2) associations with standardized functional outcomes and a biomechanical metric-stiffness-via mediation analysis; (3) discriminatory efficacy in distinguishing ALS+B and ALS-B from HC, as well as from each other, using machine learning classifications; and (4) robustness to common nonmotor confounders, including age, sex, and cognitive-linguistic impairments, through a comparison of discriminatory performance before and after adjustment for these factors. All composite measures exhibited (1) high internal consistency (Cronbach's \u03b1 = 0.89 \u00b1 0.071 ), (2) significant (or marginally significant) direct or stiffness-mediated indirect associations with the functional outcomes, and (3) consistently high discriminatory accuracy (0.82-0.85), both before and after adjustment for confounders. The sEMG framework demonstrates strong potential as a reliable, valid, and robust objective tool to detect subclinical neuromuscular changes throughout the prodromal and symptomatic phases of bulbar involvement in ALS, while remaining resistant against disease-related cognitive-linguistic impairments and disease-unrelated confounders. This tool may augment standard clinical evaluations, enabling earlier detection of bulbar involvement and measurement-based care in ALS.",

Patient demographics, clinical and laboratory data, treatments, and outcomes were analyzed descriptively. Fifty-two patients were included. Sinomicrurus macclellandi was the most frequently reported species. Most bites occurred during the rainy season and involved the lower extremities. Clinical manifestations were predominantly mild and localized. No cases of systemic neurotoxicity, bulbar weakness, respiratory compromise, or death were observed. Laboratory results were generally within normal limits. Two patients developed anaphylaxis, which resolved with standard emergency treatment, while two experienced severe pain. Calliophis intestinalis lineata was associated with a higher proportion of tachycardia at presentation and longer hospitalization. No patients required mechanical ventilation or antivenom therapy. Supportive care and short-term hospital observation are generally sufficient in confirmed cases. The median duration of hospitalization was 1-3 day. Local manifestations were the predominant clinical findings following Asian coral snake envenomation in Thailand, and systemic neurotoxicity was not observed. These findings differ from reports of Micrurus envenomation, which primarily involve New World coral snakes, whereas the species implicated in Thailand belong to Old World genera.",

Due to the rarity of the procedure, the risks and yield of stalk biopsy are not well known, with important implications for clinical decision making. METHODS: A systematic review was performed in accordance with the PRISMA statement. Studies that reported diagnostic yield and complication rates after stalk biopsy were included. Bias was assessed using ROBINS-V2. RESULTS: A total of 13 studies, including 832 patients and 406 biopsies were included. Mean time from diagnosis to biopsy was 11 months. Preoperative visual symptoms were seen in 29.1%, AVP-deficiency (diabetes insipidus) in 71.0%, and hypopituitarism in 66.3%. Biopsy was predominately performed through the endoscopic transsphenoidal approach (70.9%). Diagnostic yield was 95.8%, and complications included postoperative CSF leak (1.6%), visual worsening (1.6%), new cranial nerve palsy (1.2%), new permanent AVP-deficiency (9.0%), new hypopituitarism (15.7%), and meningitis (2.7%). CONCLUSION: Pituitary stalk biopsy is a high yield and safe diagnostic test, with low periprocedural morbidity. The rate of new endocrinopathy compares favourably to the natural history of progressive stalk disease. Stalk biopsy could be considered earlier in the workup of undifferentiated progressive or symptomatic stalk lesions to avoid unnecessary delays in diagnosis and treatment.",

We hereby report the largest cohort with SLC52A3-related BVVL from the Arabian Peninsula. A total of 23 patients, 16 females and 7 males, with genetically confirmed BVVL diagnosis at two tertiary centers from the region were retrospectively\u00a0reviewed. Most patients were clinically ascertained (13/23), while 10 patients were diagnosed pre-symptomatically. 20 patients were homozygous for SLC52A3: c.634C>T (p.Arg212Cys) variant and 3 patients were homozygous for SLC52A3: c.1325_1326del. Facial diplegia was the commonest clinical feature (12/13), while moderate to severe hearing loss and dysarthria were seen in (10/13) patients. Symptomatic patients were treated with riboflavin doses ranging between 15 and 100\u2009mg/Kg/day, with a median of 26\u2009mg/Kg/day. Pre-symptomatic patients were treated with doses lower than that (as low as 5\u2009mg/Kg/day). Patients were followed for 6 months to 12 years, with a median of 4 years. Most patients have shown significant or near-total recovery with residual symptoms (11/13), while 9/10 patients diagnosed pre-symptomatically remained symptom-free, and 2 symptomatic patients showed complete resolution of symptoms.

X-linked hypophosphatemia (XLH) is a rare genetic disorder characterized by impaired phosphate homeostasis due to renal phosphate wasting. It leads to osteomalacia and skeletal abnormalities and represents the most common inherited cause of vitamin D-resistant rickets. In some patients, heterotopic ossification of the ligamentum flavum and paravertebral ligaments may result in spinal cord compression and myelopathy. Due to its rarity, large case series evaluating patient characteristics and surgical outcomes are lacking. We conducted a PRISMA-P based systematic review on spine surgery and X-linked hypophosphatemia from 1960 to 2022. Twenty-five studies were included, comprising 32 clinical cases. An illustrative case is also presented. Thirty-two patients (16 females and 16 males) with spinal cord compression due to XLH were included in this systematic review. Thirty out of 32 patients underwent surgery (one death and one refusal of surgery). The mean age of onset of symptoms was 41\u00a0years. 83% (25/30) had reduction of their symptoms after surgery, and 57% (17/30) had full recovery post-operatively.

Following uncomplicated surgical debridement and discharge, the patient returned within hours exhibiting rapidly progressive ascending paralysis, bulbar weakness, and respiratory failure requiring intubation. Laboratory evaluation revealed profound hypokalemia (1.4 mmol/L), hypophosphatemia, and rhabdomyolysis. The clinical presentation, coupled with the patient's report of the firework emitting a green flare, is most consistent with acute barium toxicity. Formal toxicologic confirmation was not available; however, the clinical constellation, mechanism of injury, and rapid response to electrolyte repletion strongly support this diagnosis. Barium salts, commonly used in pyrotechnics to produce green coloration, can induce systemic toxicity by competitively blocking potassium channels, causing a widespread intracellular shift of potassium. This case highlights the rare but life-threatening systemic toxicity associated with soluble barium salts and the importance of considering toxicologic etiologies in trauma patients presenting with unexplained neurological collapse.",

Plasma exchange (PLEX) and intravenous immunoglobulin (IVIg) are two rescue therapies that show comparable efficacy in this setting. However, the characteristics of patients who respond poorly to IVIg remain insufficiently described. The aim of this study was to identify predictive factors of non-response to IVIg administered during a first MC or exacerbation. This was a single-centre retrospective cohort study carried out at a French referral centre for neuromuscular diseases between 2017 and 2023. Adult patients with generalised MG experiencing a first MC or exacerbation and treated for the first time with IVIg were included in the study. Data on clinical, laboratory, electrophysiological and therapeutic variables were collected. Treatment response was defined as the maximum gain in Garches clinical score following IVIg, adjusted for baseline score. A total of 93 were included in the study. The median age of the cohort was 68 (interquartile range [IQR] 49-76) years, and the median delay from diagnosis was 0.7\u00a0years. The median baseline Garches score was 66/100 (IQR 55-75) points, which improved to 85/100 (IQR 75-94) points after treatment. Bulbar involvement was significantly associated with a greater response to IVIg. In this large and heterogeneous cohort, IVIg demonstrated consistent efficacy without identification of significant predictors of non-response. These findings support IVIg as a reliable and evidence-based first-line therapy for patients with MG experiencing exacerbation or MC.",

In many low-income settings, access to mechanical ventilation and disease-modifying therapy is limited. We describe the management of a young woman with rapidly progressive GBS and bulbar weakness in a mission hospital in northern Madagascar without access to intensive care facilities, invasive ventilation or immunotherapy. Respiratory failure was managed using a structured high-dependencyunit (HDU) framework combining noninvasive respiratory support with intensive nursing care, physiotherapy, regular repositioning and close nurse-led observation. The patient survived the acute phase, regained swallow and speech by Day 8 and was discharged from HDU on Day 15. At 1-year follow-up, she had recovered full upper limb strength with residual lower limb weakness. This case highlights the potential for structured supportive care in an HDU to sustain life in clinically significant neuromuscular respiratory failure when definitive critical care resources are unavailable.",

It most commonly affects the nasal cavity and sinuses. While only few of cases of third cranial nerve palsy have been reported in association with diffuse large B-cell lymphoma and Burkitt lymphoma, its occurrence as a presenting feature of ENKTL is exceptionally rare. Here, we present a patient with isolated third cranial nerve palsy as the initial manifestation of relapsed ENKTL. A 67-year-old woman with a history of ENKTL in remission was admitted with bilateral periorbital swelling, nasal purulent discharge, and congestion following nasal reconstruction. She was diagnosed with preseptal cellulitis and sinusitis and subsequently treated with IV antibiotics. She later developed a right third nerve palsy with pupillary involvement. A CT angiogram ruled out an aneurysm, however brain MRI showed perineural spread affecting the cavernous sinus. Further cranial nerve involvement prompted a biopsy of the sinus, confirming ENKTL. A PET scan was done. No uptake in the brain, sinuses, or the rest of the body was observed. A bone marrow biopsy was subsequently performed revealing marrow involvement with ENKTL, suggesting metastatic spread beyond the sinuses. Unfortunately, the patient developed sepsis and subsequently passed away. This case emphasizes the importance of early consideration of malignancy who present with atypical neurological symptoms. Given the risk of false-negative imaging results, a multimodal approach is essential. This should include high-resolution MRI coupled with neuroradiological review, biopsy with histopathological analysis when feasible, FDG PET scan and lumbar puncture with CSF analysis.",

This review summarizes the diagnostic challenges and potential management of adults with IIHWOP. A detailed search of the scientific literature, combining MeSH and free-text terms, included all English-language papers on PubMed, from inception to June 8, 2025. In this review, we used the term IIHWOP to describe patients without evidence of active or previous papilledema. The diagnosis of IIHWOP is based on elevated lumbar puncture opening pressure accompanied by either sixth cranial nerve palsy or neuroimaging features of intracranial hypertension, which may lack specificity. Clinical presentation frequently mimics primary headache disorders, and lumbar puncture remains an invasive procedure without clear management implications in IIHWOP, as there are no high-quality studies evaluating medical or surgical therapies. Recommendations for investigation and clinical care remain largely inferred from idiopathic intracranial hypertension. Given the absence of evidence for risk of vision loss, invasive procedures should be avoided, and management should focus on weight loss and optimized headache management.",

This communication can be either high-flow or low-flow. Depending on the distinct anatomy of the shunt, it has effects on the various neurovascular structures that lie within the cavernous sinus. To evaluate the immediate\u00a0outcomes of CCF patients undergoing surgical and endovascular management. This is a retrospective observational study conducted at\u00a0the Departments of Neuroendovascular Surgery and Neurosurgery at Punjab Institute of Neurosciences, Lahore. Consecutive patients diagnosed with CCF, who underwent diagnostic evaluation or treatment at the institution between\u00a0January 2023 and December 2025, were included.\u00a0Descriptive statistics were applied to analyze characteristics and outcomes. Of the total 10\u00a0patients, the most common clinical presentation was proptosis (90%; n=9), followed by chemosis (40%; n=4), ophthalmoplegia (30%; n=3), and cranial nerve palsy (10%; n=1). The majority of these cases were high flow (80%; n=8), categorized as being Barrow A. Arterial feeders originated exclusively from the internal carotid artery (ICA) in 60% (n=6) of cases, while 10% (n=1) were from the external carotid artery (ECA). Anterior and posterior drainage of CCF was mediated by the superior ophthalmic veins (SOV) (40%; n=4) and inferior petrosal veins (IPV) (20%; n=2), respectively. The majority of patients in our case series underwent stent (PK Papyrus, Biotronik SE & Co. KG, Berlin, Germany)\u00a0placement, i.e., 70% (n=7), followed by ICA ligation in 20% of cases (n=2). Postoperative imaging revealed a fistulous leak in 60% (n=6), complete obliteration in 10%, and mild flow in 1% (n=1). Clinical outcomes improved in 90% (n=9), and no post-procedural hemorrhage, infarction, or cranial nerve deficit was reported. Most of the patients had neuro-ophthalmic manifestations. Direct-type CCFs were the common type\u00a0in our small case series,\u00a0affecting the male gender predominantly, and most cases were post-traumatic. The endovascular management of CCF using covered stent deployment (PK Papyrus) yields reasonable radiological obliteration of the fistula, improved visual outcomes, and minimal intraoperative and immediate postoperative complications.",

While genetics plays a clear role, it cannot explain why symptoms start focally or how upper (UMN) and lower motor neuron (LMN) systems are linked. In this clinicopathological case series, we examined the relationships between UMN/LMN disease in ten ALS patients. Detailed clinical assessments and motor cortex, brainstem, and spinal cord tissues were collected via rapid autopsy. Tissues were stained for UMN/LMN, myelin, axons, microglia, and pTDP43, and RNA-sequencing was performed. None of the patients had symptoms of frontotemporal dementia (FTD), but all had focal sites of clinical onset and both UMN/LMN involvement. LMN degeneration and microglial activation were highest at disease onset sites. UMN degeneration was present at all spinal cord levels through the medulla, regardless of onset site. Surprisingly, there was no evidence of UMN axonal degeneration above the brainstem. While extensive pTDP43 aggregates were seen in degenerating LMNs, no pTDP43 aggregates were seen in UMN cell bodies or their axons. RNA-sequencing implicated inflammatory pathways at sites of disease onset. Our findings suggest that some ALS patients without FTD have a dying back of UMN axons rather than a primary upper neuronopathy of neurons.",

Rare potential adverse events have been reported in case reports, but risks among older adults remain unclear. This study assessed risks of selected potential adverse events in this population. We included more than 2 million Swedish adults \u226565y in a nationwide register-based cohort. Post-vaccination risks were assessed for herpes zoster (HZ), encephalitis, myelitis and encephalomyelitis, multiple sclerosis (MS), myasthenia gravis, cranial nerve palsy, sudden sensorineural hearing loss (SSNHL), postinfectious arthritis and polymyalgia rheumatica (PMR) in several risk windows (1-30, 31-60, and 61-180\u00a0days) after each vaccine dose. Hazard ratios (HRs) with 95% confidence intervals (95%CIs) compared with unvaccinated were estimated by Cox regression adjusted for potential confounders. Sensitivity analyses included adding primary health care (PHC) visits, and applying analysis-specific 5-year disease-free wash-out periods. No increased HRs were observed for most outcomes. SSNHL showed increased HRs within 180\u00a0days after each dose [1.60 (95%CI 1.15-2.24); 1.43 (1.03-1.99); 1.61 (1.05-2.46) for dose 1, 2 and 3], with similar estimates across all three risk windows. Increased HRs were also seen for PMR after dose 2 [1.14 (1.04-1.24)] and dose 3 [1.16 (1.03-1.30)], with higher HRs during later time windows. HZ showed increased HRs in the sensitivity analysis with PHC visits, [1.19 (1.07-1.31); 1.31 (1.19-1.43); 1.42 (1.26-1.60) for dose 1, 2 and 3]. MS showed reduced risk after dose 3 in the sensitivity analysis with longer wash-out (targeting incident MS), but not in the main analysis (potential relapses included). COVID-19 vaccines are generally safe in older adults, with very low incidence of the potential rare adverse events assessed. Slightly increased relative risks for SSNHL, PMR and HZ were observed, but these findings do not alter the overall benefit-risk profile of COVID-19 vaccination in older adults.",

However, emerging non-immune effector cell-associated neurotoxicity syndrome (non-ICANS) neurologic events-including cranial nerve palsy (CNP) and immune effector cell (IEC)-parkinsonism (also called movement and neurocognitive toxicity)-warrant vigilance. This review summarizes clinical findings from the CARTITUDE trials, which evaluated ciltacabtagene autoleucel in > 300 patients with RRMM. CNP occurred in 6.3% of patients, with a lower incidence in more heavily pretreated patients (\u2265 3 prior lines of treatment [pLOT]: 3% vs. 1-3 pLOT: 9%). Median CNP onset was day 22 postinfusion; most cases were low grade, and 90% recovered completely. IEC-parkinsonism involves motor, cognitive, and personality changes; lower incidence was observed in less heavily pretreated patients (1% vs. 6%). Median time to onset was 56 days postinfusion; however, with greater awareness, IEC-parkinsonism may be recognized earlier. Emerging data suggest that early, aggressive intervention may result in better outcomes. High CAR-T cell expansion is associated with increased risk of CNP and IEC-parkinsonism. In the early postinfusion period (days 10-28), absolute lymphocyte count (ALC) strongly correlates with circulating CAR-T cell levels and could help identify patients at increased risk of neurologic events. Prophylactic interventions, including a short course of steroids, triggered by elevated ALC before symptom onset, are under investigation. Education of patients, caregivers (including family), local oncologists, and neurologists seeing patients outside CAR-T infusion centers is essential to facilitate timely recognition, referral to the CAR-T center, and management.",

We aimed to characterize the clinical phenotype, upper motor neurone (UMN) sign prevalence, survival, and functional milestones. We retrospectively analyzed 78 patients with ALS8 confirmed via molecular testing or familial linkage analysis from 57 apparently unrelated families. UMN signs were assessed using a five-item composite of pyramidal signs. Survival and milestones were estimated using Kaplan-Meier analysis. Median age at onset was 44.9\u2009years; 51% were men. Onset was lumbar in 94%, proximally predominant. UMN signs were present in 53 patients; none exhibited clonus. At admission, 51% had spinal-onset ALS, 42% progressive muscular atrophy (PMA) and 6% flail leg; 30% of patients with PMA subsequently developed UMN signs. Survival was 21.9\u2009years; times to wheelchair dependence and noninvasive ventilation were 7.0 and 10.0\u2009years, respectively. Bulbar involvement occurred in 17 (21.8%) patients, predominantly as dysphonia. UMN status did not affect survival (p\u2009=\u20090.312). The standardized mortality ratio was 4.54 (95% CI 2.77-7.01), supporting disease-related excess mortality. ALS8 is a slowly progressive motor neurone disease with lumbar onset, ascending progression, and frequent but subtle UMN signs. Survival was markedly prolonged but functional decline followed a predictable sequence. These findings expand the phenotypic characterization of ALS8 and support genetic counseling and anticipatory management.",
        "42168009": "ID: 42168009\nTitle: Primary Lateral Sclerosis French National Diagnostic and Care Protocol.\nAbstract: Primary lateral sclerosis (PLS) is a rare neurodegenerative motor neuron disease characterized by progressive and selective involvement of the central motor neuron within the bulbar and spinal regions. It is estimated to account for 1-5% of motor neuron diseases and typically presents in the fifth or sixth decade of life, with a slight male predominance. According to current consensus criteria, the diagnosis relies on the demonstration of progressive upper motor neuron dysfunction in the absence of lower motor neuron involvement, with persistence of isolated upper motor neuron signs for at least four years in order to exclude a slowly progressive upper motor neuron-predominant form of amyotrophic lateral sclerosis (ALS). The French Motor Neuron Disease Network (FILSLAN) developed a National Diagnostic and Care Protocol (PNDS) with the aim of standardizing diagnostic criteria, optimizing differential diagnosis, and providing evidence-based recommendations for therapeutic management and follow-up across the national territory. These recommendations were elaborated in accordance with the methodological framework of the French National Authority for Health for rare diseases. The protocol provides practical guidance for establishing PLS as a diagnosis of exclusion, distinguishing it from ALS and hereditary spastic paraplegias, and organizing appropriate clinical and paraclinical investigations. It also outlines indications for genetic testing in selected cases and defines a multidisciplinary management strategy centered on symptomatic treatment, early rehabilitation, respiratory and nutritional surveillance, and psychosocial support. Given the slower progression of PLS compared with ALS, biannual multidisciplinary follow-up is generally appropriate. This protocol aims to harmonize clinical practice and improve patient care while acknowledging the current absence of disease-modifying therapies.",

A consensus clustering method is proposed to identify stable clusters across multiple random data sub-samples, with the objective of discovering whether the retrieved patients' groups and related features align with clinical phenotypes and medical knowledge.

Creatinine (Cre) reflects muscle mass, whereas cystatin C (CysC) may reflect neurodegeneration without being directly influenced by muscle mass; however, both have limitations. We aimed to investigate whether the creatinine-to-cystatin C ratio (Cre/CysC) was cross-sectionally associated with functional status in patients with ALS. We retrospectively analyzed 30 patients diagnosed with ALS at the National Organization Hospital Okinawa Hospital between 2021 and 2024. Baseline ALS Functional Rating Scale-Revised (ALSFRS-R) scores and serum Cre and CysC levels were recorded. Associations with the ALSFRS-R were assessed using Spearman's correlation, with subgroup analyses by sex, site of onset, age at diagnosis, body mass index (BMI), and diagnostic delay. Multivariable analyses were performed to examine the independent association between Cre/CysC and ALSFRS-R while accounting for relevant clinical covariates. Cre/CysC showed a stronger cross-sectional correlation with ALSFRS-R (rs=0.648, p\u2009=\u20090.0001) than Cre alone (rs =0.427) or CysC (rs =-0.119). Exploratory subgroup analyses showed generally positive associations in several subgroups, although no statistically significant association was observed in the small bulbar-onset subgroup. In multivariable analysis adjusted for age at onset and diagnostic delay, Cre/CysC remained independently associated with ALSFRS-R (\u03b2\u2009=\u200920.1, 95% CI 6.41-33.9, p\u2009=\u20090.006). Given the small sample size and cross-sectional design, these findings should be interpreted as exploratory. Cre/CysC showed a stronger cross-sectional association with functional status than either marker alone. Because it is derived from routine laboratory tests, Cre/CysC may represent a simple exploratory measure associated with functional status in ALS. However, the present findings do not establish prognostic utility or fully account for disease stage and biological heterogeneity. Prospective longitudinal studies incorporating disease progression measures and broader clinical and genetic characterization are warranted.",

Neoplastic causes are most commonly involved, while benign tumors such as paragangliomas are infrequent etiologies. We report a 58-year-old woman who presented with progressive dysphagia and unilateral lower cranial nerve dysfunction. Clinical examination demonstrated right-sided palsy of cranial nerves IX, X, XI, and XII. Magnetic resonance imaging revealed a lobulated, avidly enhancing lesion centered in the right hypoglossal canal with extension into the jugular foramen and adjacent carotid space, radiologically suggestive of a skull base paraganglioma.

The most common subtype, amyotrophic lateral sclerosis (ALS), is characterized by both upper and lower motor neuron impairment, which can manifest clinically in the bulbar region or asymmetrically in a limb. Typically, the disease progresses over several months, and death from respiratory failure occurs within 2-5\u2009years of onset. As we highlight in this Review, data on MND in Africa are sparse, although common observations in this region - and in other populations with relatively low life expectancy - include apparent earlier disease onset and lower disease incidence compared with the rest of the world. In\u00a0view of the HIV epidemic in Africa, we critically examine the evidence for an association between ALS and HIV infection. We briefly discuss conditions that might be regarded as ALS mimics and summarize the limited data on MND genetics in this region. Other issues pertinent to people living with MND in Africa include the absence of cognitive and behavioural data and the limited access to multidisciplinary clinics, therapies and palliative care.

A minimum disease duration of 2 years is required for the diagnosis of PLS, after which patients are classified as probable PLS (P-PLS) and subsequently as definite PLS (D-PLS) after 4 years. Our aim is to apply the current diagnostic criteria to a population-based cohort and investigate which clinical characteristics are associated with a diagnostic revision to ALS. This cohort study included patients meeting the current diagnostic criteria for PLS retrospectively from the Dutch Motor Neuron Disease Registry. Diagnostic revision to ALS was based on clinical assessment, EMG findings according to the revised El Escorial Criteria, or if patients had died from disease progression within 4 years of disease onset. Clinical characteristics were compared for patients who underwent diagnostic revision with ALS vs true PLS. Subdistribution hazard ratios (SHRs) for characteristics associated with diagnostic revision were determined using Fine-Gray regression. We included 478 patients (median age of onset 59.3 years, interquartile range 50.8-67.0, 47.9% female), of whom 311 (65.1%) met criteria for P-PLS and 167 (34.9%) for D-PLS at diagnosis. Eighty-eight patients (18%) underwent diagnostic revision to ALS, 76 cases (86%) before 4 years of disease duration. Patients whose diagnosis was revised to ALS had higher median age at onset (63.4 vs 58.0 years, p = 5.20 \u00d7 10-4), more often had bulbar onset (38.6% vs 19.7%, p = 6.19 \u00d7 10-4), and faster progression (median ALS Functional Rating Scale-revised slope 0.43 vs 0.18, p = 6.05 \u00d7 10-11). The risk of diagnostic revision increased if progression rate was faster (SHR 3.08 95% CI 1.69-5.60, p = 2.35 \u00d7 10-4) and if diagnosis was P-PLS compared with D-PLS (SHR 3.08, 95% CI 1.65-5.74, p = 3.96 \u00d7 10-4). In our cohort, most diagnostic revisions from PLS to ALS were in patients with a disease duration of less than 4 years. Besides disease duration, a faster progression rate was associated with diagnostic revision from PLS to ALS. Adding progression rate to the current diagnostic criteria could increase accuracy and help identify patients at higher risk of developing ALS.",

This paper represents Part II of a two-part study on EOMSs. While Part I addressed tumor localization, clinical features, and surgical approaches, the present paper focuses on surgical outcomes and prognostic factors for postoperative neurological function. Systematic review identified surgically treated EOMS. Of 156 patients found, 117 had complete pre-/postoperative data; with the three institutional cases, 120 patients were analyzed. Variables extracted were tumor size, extent of resection (EOR), cavernous sinus involvement (CSI), and postoperative function of the nerve of origin. Univariate and multivariable logistic regression identified predictors of persistent postoperative origin nerve-related deficits. The cohort comprised 52 CN III (43.3%), 34 CN IV (28.3%), and 34 CN VI (28.3%) tumors. Mean diameter was 30.1 mm. CSI occurred in 43.3% (more frequent in CN III and CN VI). Gross-total resection (GTR) was achieved in 69.2% overall and more often in CN IV (94.1%). Preoperative nerve deficits were present in 73.3%; among these, postoperative improvement occurred in 31.8%. New postoperative palsy developed in 40.6% of patients without preoperative palsy. At final follow-up, persistent nerve-of-origin deficits were present in 60.0%. On multivariable analysis, tumor diameter\u2009\u2265\u200935 mm (OR 2.47, 95% CI 1.06-5.73; p\u2009=\u20090.0354), CSI (OR 2.56, 95% CI 1.05-6.27; p\u2009=\u20090.039), and trochlear origin versus abducens (OR 3.24, 95% CI 1.03-10.1; p\u2009=\u20090.0438) were independently associated with persistent origin nerve-related deficits. Persistent nerve-of-origin deficits are common after EOMS surgery.

Non-immune effector cell-associated neurotoxicity syndrome (ICANS) neurologic events (NEs) may occur following infusion. This real-world study evaluated non-ICANS NE onset and management among patients with RRMM treated with cilta-cel. Electronic medical records from Loopback Analytics (02/2022-05/2025) were used, supplemented with physician notes. Adults treated with cilta-cel after 1-3 and \u22654 prior LOT were included (N=171). New-onset non-ICANS NEs included cranial nerve palsy (CNP), parkinsonism, and Guillain-Barr\u00e9 syndrome. Clinical outcomes among these patients were described. Among 171 patients, 73\u00a0had 1-3 prior LOT and 98\u00a0had \u22654 prior LOT. Among patients with 1-3 prior LOT (median follow-up: 6.1 months), CNP occurred in 4 patients, while no parkinsonism or Guillain-Barr\u00e9 syndrome were observed. Following CNP onset, symptoms improved among 3 patients. Among patients with \u22654 prior LOT (median follow-up: 17.4 months), CNP occurred in 3 patients, while parkinsonism and Guillain-Barr\u00e9 syndrome each occurred in 1 patient. All patients with CNP had symptom improvement and the patient with Guillain-Barr\u00e9 syndrome had symptom resolution. Median peak ALC (103 cells/\u00b5L) was higher in patients with versus without non-ICANS NEs (1-3 prior LOT: 7.60 vs 2.12; \u22654 prior LOT: 11.64 vs 1.96). All patients with events had at least a partial response to cilta-cel and remained alive at the end of follow-up. This real-world cohort showed low incidence of CNP, parkinsonism, and Guillain-Barr\u00e9 syndrome following cilta-cel. Elevated post-infusion ALC warrants further investigation into its role as a biomarker to inform monitoring and management strategies, consistent with prior reports. Most patients with CNP reported improvement, the patient with Guillain-Barr\u00e9 syndrome reported resolution, all patients with available response assessments responded to cilta-cel, and no deaths were reported.",

MRI demonstrated new infarcts in the left cerebral peduncle, posterior limb of the internal capsule, thalamus, and temporal lobe, superimposed on a prior pontine lesion. This distributed but strategically located pattern of injury affected bilateral corticospinal pathways and explained the profound motor impairment despite preserved consciousness. This case highlights how PLIS may mimic encephalopathy in the acute care setting and underscores the importance of structured bedside assessment for detecting preserved awareness in mute or immobile patients. Early recognition has implications for airway management, stroke evaluation, communication strategies, and prognostic counseling.",

We report a single-center case series of 8 consecutive patients who developed TMOS during immune checkpoint inhibitor therapy for solid malignancies between 2023 and 2025. Median age was 76 years and median time to symptom onset was 14.5 days after exposure. All patients had myositis symptoms; 5 required mechanical ventilation and 1 subsequently required tracheostomy. Cardiac involvement was characterized by troponin elevation and frequent electrical abnormalities, including complete atrioventricular block, ventricular tachyarrhythmias, and bundle branch block, despite preserved left ventricular systolic function on imaging. Corticosteroid monotherapy was insufficient in practice, and all patients required additional immunomodulatory therapy. TMOS requires early recognition, close monitoring, and rapid multidisciplinary escalation of care.",

MG is an autoimmune neuromuscular junction disorder, whereas CKD exhibits the gradual loss of kidney function. We report a 65-year-old male with long-standing CKD who developed progressive neuromuscular symptoms, including bilateral ptosis and bulbar involvement. His anti-acetylcholine receptor antibodies were negative; however, electrophysiological studies demonstrated a significant decremental response (>\u200910%) on repetitive nerve stimulation, supporting the diagnosis of MG. The patient required hemodialysis for worsening renal function and was treated with pyridostigmine for MG symptoms, resulting in clinical improvement. This case emphasizes the importance of distinguishing MG from CKD-related symptoms, particularly in seronegative patients, and highlights the need for careful clinical and electrophysiological evaluation.",

However, partial pupil-sparing third cranial nerve palsy is an uncommon presentation in this population and may be misleading, as it is often presumed to be ischemic. We report an atypical presentation of cerebral toxoplasmosis manifesting as partial pupil-sparing third nerve palsy. We report the case of a 37-year-old HIV-positive male with advanced human immunodeficiency virus infection who presented with headache, seizures, and binocular diplopia and was found to have a partial pupil-sparing third nerve palsy. Neuroimaging revealed multiple intracranial enhancing lesions with surrounding vasogenic edema. Cerebrospinal fluid analysis demonstrated varicella zoster virus positivity, and stereotactic brain biopsy ultimately confirmed cerebral toxoplasmosis. The patient was managed with antimicrobial therapy and showed clinical improvement. In patients with human immunodeficiency virus infection, pupil-sparing third nerve palsy should not be presumed to be exclusively ischemic, as infectious and other opportunistic etiologies may underlie its presentation. Careful clinical assessment, detailed examination, and appropriate neuroimaging are essential for accurate diagnosis and timely management.",

This retrospective cross-sectional study evaluated the frequency of sensory and entrapment neuropathies in 114 patients with ALS using electrodiagnostic (EDX) studies. Demographic characteristics, comorbidities, and sensory and autonomic symptoms were documented. Electrophysiological evidence of sensory neuropathy was identified in 20 patients overall (20/114, 17.5%), including 10 patients without diabetes mellitus (DM), whereas entrapment neuropathy was detected in 28 patients overall (28/114, 24.6%), including 16 of those without DM or hypothyroidism. Sensory neuropathy was significantly associated with both DM and a history of chronic disease. In contrast, these comorbid conditions were not significantly associated with entrapment neuropathy. Furthermore, patient-reported symptoms showed no correlation with electrophysiological evidence of sensory involvement on EDX. Sensory neuropathy was more frequent in patients with spinal-onset than bulbar-onset disease, although the difference was not statistically significant. This study confirms that sensory involvement is not uncommon in ALS. Although clinical symptoms are poor predictors, electrophysiological abnormalities consistent with sensory and entrapment neuropathies are common. A significant proportion of these abnormalities are idiopathic and may directly reflect the disease process itself, particularly in spinal-onset cases.",

Our aim was to describe the clinical characteristics, paraclinical features, and recovery outcomes of children with GBS. This is a prospective study of 40 children diagnosed with GBS from January 2021 to December 2022. Data on demographics, clinical features, treatments, complications, and outcomes were collected at follow-up time points based on the Guillain-Barr\u00e9 disability score (GDS). In the study of 40 children, the number of male children with GBS was predominant (82.5%), and more than 50% of GBS patients were older than 10 years. Seventy-five percent of patients with GBS had a preceding infection, with respiratory tract infections being the most common. The most common initial symptom was leg pain. Bulbar palsy was observed in 47.5% of patients and was a relatively frequent clinical feature in our cohort. Albuminocytological dissociation (ACD) rate within the first 7 days was 73.3%. Based on nerve conduction study results, the phenotypes were distributed as follows: acute inflammatory demyelinating polyneuropathy (AIDP) accounted for 55%; acute motor-sensory axonal neuropathy (AMSAN) for 17.5%; acute motor axonal neuropathy (AMAN) for 10%; inexcitable nerves for 5%; and unclassifiable cases for 12.5%. At the 6-month follow-up, 100% of pediatric patients achieved independent ambulation. Furthermore, a correlation was found between mechanical ventilation and GDS at 1 and 2 months; however, no association was observed at 3 and 6 months' postonset. In pediatric GBS, the most common initial manifestations are limb pain and paresthesia. Most patients achieve good recovery; the need for mechanical ventilation is associated with bulbar weakness, facial paralysis, pneumonia, and severe initial limb weakness.",

All coding exons and flanking intronic regions of FUS were analyzed by Sanger sequencing in 650 unrelated Taiwanese patients with ALS. Clinical characteristics of patients carrying FUS variants were evaluated. Haplotype analysis using polymorphic microsatellite markers flanking FUS was performed to assess a potential founder effect of the p.H517D variant. Eight distinct heterozygous pathogenic FUS variants were identified in 11 probands and five affected relatives, including six missense and two frameshift variants. The most frequent variant was p.H517D, detected in four probands. A novel frameshift variant, p.G499Vfs*30, was identified as a de novo mutation in a juvenile-onset ALS patient. Compared with the non FUS-associated ALS cohort, patients with FUS-associated ALS had a significantly younger mean age at onset (40.1 vs 56.6\u00a0years) and more frequent bulbar onset (50% vs 19%). Haplotype analysis suggested a common founder for the p.H517D variant. FUS mutations accounted for 1.7% of ALS cases in this Taiwanese cohort. The recurrent p.H517D variant appears to represent a population-specific founder mutation. Patients with FUS variants presented with earlier disease onset and heterogeneous clinical phenotypes, and de novo variants contributed to juvenile-onset disease.",

Although many patients recover with rehabilitation, some exhibit persistent functional deficits. In such cases, detailed pathophysiologic evaluation may assist in guiding surgical intervention to improve outcomes. A 77-year-old woman presented with severe dysphagia and hoarseness after resection of a right cerebellopontine angle meningioma, which caused glossopharyngeal, vagus, and accessory nerve palsies. Despite initial recovery, she developed repeated aspiration pneumonia and malnutrition. Comprehensive reassessment using high-resolution manometry (HRM) and dynamic swallowing computed tomography (CT) revealed right-sided velopharyngeal insufficiency, pharyngeal constrictor dysfunction, vocal fold paralysis with paramedian fixation, and impaired upper esophageal sphincter relaxation. A tailored multi-procedural surgical approach was performed, including right pharyngeal flap, arytenoid adduction, right hypopharyngeal pharyngoplasty with expanded polytetrafluoroethylene mesh reinforcement, right cricopharyngeal myotomy, and tracheostomy. Postoperatively, swallowing and phonation significantly improved. The patient resumed oral intake, and tracheostoma closure was performed on postoperative day (POD) 25. Maximum phonation time improved sevenfold by POD 32. She was discharged on POD 33, and resumed a regular diet with some limitations by 3 months postoperatively. Intractable dysphagia due to complex LCN dysfunction requires individualized surgical strategies. Multimodal functional assessment, including dynamic swallowing CT and HRM, aids precise evaluation and helps refine surgical planning in selected complex cases, potentially leading to significant improvements in quality of life.",

This study was a prospective randomized controlled trial. A total of 110 patients with dysphagia due to post-stroke bulbar palsy were enrolled at Baoding No.1 Central Hospital from February 2017 to December 2020. Patients were randomly assigned using a random number table to either a control group (n = 55) receiving conventional pharmacotherapy combined with rehabilitation training, or a treatment group (n = 55) receiving the same conventional therapy plus additional EMG-guided targeted injections of mecobalamin into the swallowing muscles. Swallowing function was assessed using the Wada water swallowing test (WST) and videofluoroscopic swallowing study (VFSS) after 2 weeks of treatment. The treatment group showed a significantly higher overall response rate on the WST than the control group (P < 0.05). Based on VFSS, the marked and overall effectiveness rates were 50.9% and 96.4% in the treatment group, respectively, significantly higher than the corresponding rates of 18.2% and 83.6% in the control group (both P < 0.05). The incidence of aspiration decreased significantly in both groups post-treatment (P < 0.05), with a more pronounced reduction observed in the treatment group (P < 0.05).

We aimed to systematically characterize its clinical features, diagnostic patterns, treatment strategies, and outcomes. A systematic review was conducted in accordance with PRISMA 2020 guidelines and registered in PROSPERO (CRD420251141162). PubMed, Scopus, Web of Science, and Embase were searched without language or date restrictions. Studies reporting adult patients with HNP attributable to ICAD were included. Clinical data, imaging findings, treatment modalities, and outcomes were extracted and analyzed descriptively and exploratorily. A total of 73 studies comprising 87 patients were included. The mean age was 48.5\u202fyears, and 86.2% were male. Isolated HNP was observed in 64.3% of cases, and diagnostic error occurred in 31.0%, frequently leading to delayed management. Most patients were managed medically (89.7%), and overall favorable outcomes were achieved in 65.6% of patients. Surgical or endovascular treatment was performed in a minority of cases (10.3%). The presence of pseudoaneurysm was significantly associated with increased likelihood of surgical or endovascular treatment (p\u202f=\u202f0.007) and shorter follow-up duration (p\u202f=\u202f0.015), although overall outcomes did not differ between groups. Extracranial ICAD presenting as HNP is an uncommon but clinically important condition with a substantial risk of diagnostic delay. Early vascular imaging should be considered in patients with isolated or atypical hypoglossal nerve palsy, even in the absence of ischemic lesions on brain MRI. Most patients achieve favorable outcomes with medical therapy; however, selected patients-particularly those with pseudoaneurysm or persistent or progressive symptoms-may require surgical or endovascular intervention.

Although it is often related to infection, its exact etiology remains unclear. Due to its nonspecific clinical manifestations, diagnosis typically relies on the exclusion of other conditions. Herein, we report a case of postinfectious polyneuritis cranialis. The patient presented to our hospital with restricted mouth opening, dysphagia, coughing while drinking, dysarthria, and posterior neck pain following a finger injury. Laboratory tests showed markedly elevated inflammatory markers. Neurological examination revealed involvement of cranial nerves V, IX, X, and XII. Motor nerve conduction studies of the facial nerve suggested partial facial nerve damage. Brain magnetic resonance imaging demonstrated mild nonspecific white matter changes. After exclusion of alternative diagnoses, the patient was diagnosed with polyneuritis cranialis. The patient's condition improved following corticosteroid pulse therapy and was subsequently discharged. This case highlights that the diagnosis of polyneuritis cranialis remains one of exclusion and is often clinically challenging. When encountering patients with rapidly progressive cranial nerve palsies, polyneuritis cranialis should be included in the differential diagnosis after more common structural or systemic etiologies have been excluded.",

People with thymidine kinase 2 deficiency experience progressive myopathy, bulbar weakness and respiratory insufficiency, often losing the ability to walk, eat and breathe independently. Doxecitine and doxribtimine represents the first approved treatment for patients with thymidine kinase 2 deficiency with age of symptom onset \u226412 years by the US Food and Drug Administration and the European Medicines Agency; previously, disease management was limited to supportive care. We investigated the efficacy and safety of pyrimidine nucleos(t)ide therapy in thymidine kinase 2 deficiency. Patients treated with pyrimidine nucleos(t)ides were pooled from retrospective (NCT03701568, NCT05017818) and prospective (NCT03845712) studies and company-supported Expanded Access Programs. Untreated patients were pooled from literature reviews and a retrospective chart review study (NCT05017818). Patient subgroups were stratified by age of thymidine kinase 2 deficiency symptom onset (\u226412 years and >12 years). The primary outcome was survival in 50th-percentile matched pairs of treated and untreated patients. Other outcomes included status of developmental motor milestones, ventilatory and feeding tube support, and safety. In total, 218 patients were included (treated: 104; untreated: 114). Baseline demographics and characteristics were comparable between subgroups. Most patients had an age of symptom onset \u226412 years [treated: 82/104 (78.8%); untreated: 93/114 (81.6%)]. In the age-of-symptom-onset-\u226412-years subgroup, restricted mean survival time (95% confidence interval) was 29.2 (28.2, 30.3) years over the 30 years after symptom onset for treated patients and 14.4 (11.1, 17.6) years for untreated patients. Loss of \u22651 acquired motor milestone was more frequent before treatment start than after. Substantially more patients regained \u22651 lost motor milestone after treatment start than before. Ventilatory and feeding support were used across all age-of-symptom-onset subgroups, but some patients reduced or discontinued support after starting treatment and fewer patients initiated support after treatment start than before. Most treatment-emergent adverse events (TEAEs) did not lead to discontinuation. The most frequent TEAE was diarrhoea [43/50 patients (86.0%)], which was generally mild or moderate and resolved with dose reduction. Serious TEAEs occurred in 28/50 patients (56.0%); few were considered to be drug related [4/50 (8.0%)]. In total, 3/67 patients (4.5%) experienced a fatal serious TEAE, which were not considered to be drug related. These findings indicate that pyrimidine nucleos(t)ide therapy improves survival and functional outcomes in people with thymidine kinase 2 deficiency, especially those with age of symptom onset \u226412 years, and has an acceptable safety profile.",

The Oral and Swallowing Abilities Tool (OrSAT) was originally developed to evaluate swallowing and feeding abilities in infants with SMA type I during the first two years of life. This study aimed to assess the applicability of the OrSAT in a cohort of children with SMA type I older than 2 years. Methods: Fifty-two children with genetically confirmed SMA type I, aged 2 to 12.6 years, were included. All participants had received at least one DMT, administered either soon after diagnosis or when treatment became available. Bulbar and feeding abilities were assessed using the OrSAT and results were grouped according to clinical subtype and feeding modality. Given the small sample size of the subgroups and the ordinal nature of OrSAT scores, comparisons between groups were performed using the non-parametric Kruskal-Wallis test. Results: At follow-up, 27 children were orally fed, 19 were exclusively tube-fed, and 6 were tube-fed but were also able to eat some food by mouth. The OrSAT scores reflect a wide spectrum of bulbar function from severe to no impairment. Most children who required exclusive tube-feeding at follow-up had already been tube-fed at treatment initiation, while a small number showed improvement in swallowing abilities and the partial recovery of oral feeding during follow-up. Conclusions: Our results suggest that the OrSAT, previously used only in the first two years of life, may also be applicable in older children to describe bulbar involvement and monitor changes over time. However, further studies are needed to refine the tool for this age group and to formally validate its use in older children with SMA type I. Its use may contribute to the longitudinal assessment of swallowing abilities and support rehabilitative management.",

This study aimed to investigate the relationship between clinical dysphagia assessment tools (EAT-10, GUSS, RSST, and sialorrhea severity) and videofluoroscopic swallowing study (VFSS) findings in patients with ALS. Materials and Methods: This retrospective observational study included 60 patients with ALS classified as spinal-onset (n = 38) or bulbar-onset (n = 22). Relationships between clinical assessments and VFSS findings were analysed using Spearman correlation analysis. Exploratory multivariable regression and receiver operating characteristic (ROC) analyses were performed to evaluate associations and aspiration risk discrimination. Results: Strong negative correlations were observed between PAS-Liquid and RSST and GUSS scores, whereas EAT-10 showed a strong positive correlation (all p < 0.001). ROC analyses demonstrated good discriminative ability for aspiration risk for GUSS (AUC = 0.89), RSST (AUC = 0.88), and EAT-10 (AUC = 0.82). Patients with bulbar-onset ALS demonstrated higher penetration-aspiration severity and lower functional oral intake. Conclusions: Clinical dysphagia assessment tools showed significant associations with instrumental swallowing findings in ALS. GUSS and RSST demonstrated good discriminative ability for aspiration risk and may be clinically useful bedside screening tools. However, instrumental swallowing assessment remains essential whenever feasible.",

Approximately 85% of ALS cases are sporadic (sALS), while the remaining 10%-15% are familial (fALS). Biological biomarkers of sporadic ALS remain poorly understood, hindering precise patient screening, delaying diagnosis and negatively affecting prognosis. This study aims to identify potential proteomic biomarkers by comparing the cerebrospinal fluid (CSF) of sALS patients with that of patients suffering from other neurological diseases. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used for proteomic profiling of CSF samples from 24 sALS patients and 26 patients with other neurological diseases. The complete protein expression profiles were compared using a two-tailed Student's t-test, with a p <\u20090.05 considered statistically significant with additional FDR correction at the 0.1 level. Proteomic analysis of CSF samples identified significant quantitative changes in 96 proteins with threshold p\u2009<\u20090.05 and 74 proteins with FDR <\u20090.1 between sALS and non-ALS patients, including alterations in proteins associated with neurodegenerative processes, such as amyloid precursor proteins and inflammatory markers. CSF proteomic analysis reveals altered inflammatory and neurodegenerative metabolic pathways, providing valuable insights into the proteomic landscape of sALS. Several dysregulated proteins were consistent with the disease mechanisms highlighted in previous studies. These findings represent a step forward in developing personalised approaches for diagnosing and managing the disease.",

Current standards of care guidelines focus on a multidisciplinary approach and include recommendations for nine different aspects of care. Although intended for use in all patients with SMA, the guidelines are focused on paediatric best practices and evidence regarding care provision in adults with SMA remains limited. This cross-sectional analysis of a longitudinal registry cohort of adults with SMA study aimed to evaluate the clinical features and corresponding care provision to assess alignment with current care guidelines. Data from 426 patients with genetically confirmed SMA were analysed, including information on respiratory function, bulbar involvement, musculoskeletal complications and daily living support. Results demonstrated a high prevalence of respiratory impairment, bulbar dysfunction, contractures and significant limitations in activities of daily living. However, the care provision observed in this adult cohort did not consistently reflect the recommended standards outlined in the established SMA standards of care recommendations. In particular, gaps were noted in access to respiratory support, physiotherapy and nutritional management. These findings suggest that the application of current standards of care to the adult population is inconsistent. There is a need for improved translation of care provision into adult services to ensure comprehensive and equitable management of SMA across the lifespan.",

During hospitalization, he developed ophthalmoplegia, areflexia, and ataxia, raising concern for Miller Fisher syndrome. Despite early initiation of intravenous immunoglobulin (IVIG), the patient experienced rapid neurological deterioration with bulbar involvement, leading to respiratory failure requiring mechanical ventilation.

The reliability of pupil involvement for distinguishing non-microvascular causes remains uncertain. To describe the etiologic spectrum of isolated third cranial nerve palsy and evaluate the diagnostic performance of pupil involvement and the yield of neuroimaging. This retrospective observational study reviewed adult patients with isolated third cranial nerve palsy at Mukdahan Hospital, Thailand, between January 2015 and August 2025. Patients with traumatic, postoperative, recurrent, multiple cranial nerve palsies, or incomplete records were excluded. Clinical features, neuroimaging findings, etiologies, and outcomes were analyzed. Of 61 records assessed, 51 patients were included. Mean age was 62.3 \u00b1 8.7 years, and 26 patients (51.0%) were male. Presumed microvascular ischemia was the most common etiology (42/51, 82.4%). Non-microvascular causes were identified in 9 patients (17.6%), including aneurysm in 6, nasopharyngeal carcinoma in 1, cavernous sinus meningioma in 1, and invasive aspergillosis in 1. Pupil involvement was more frequent in the non-microvascular group than in the presumed microvascular group (66.7% vs 23.8%, p = 0.020). Sensitivity, specificity, positive predictive value, and negative predictive value were 66.7%, 76.2%, 37.5%, and 91.4%, respectively. In multivariable analysis, pupil involvement remained independently associated with non-microvascular etiology (adjusted OR 8.00, 95% CI 1.49-42.85, p = 0.015). The diagnostic yield of neuroimaging was 18.8% overall and 25.0% among patients undergoing vascular imaging. Pupil involvement was associated with non-microvascular etiology but had only moderate diagnostic performance; pupil sparing did not reliably exclude clinically significant lesions. These findings suggest that vascular imaging may be clinically informative when structural causes cannot be confidently excluded, particularly given that all non-microvascular cases in this cohort were identified through vascular imaging.",

There are two main groups of presynaptic CMS: one in which the amount of ACh in synaptic vesicles (SV) is diminished and another in which the mechanism of synaptic vesicle release is impaired. The latter is often referred to as a congenital Lambert-Eaton myasthenic syndrome (LEMS). Presynaptic CMS, like other forms of CMS, is primarily characterized by muscle weakness and fatigue, but is often associated with additional manifestations of central and autonomic nervous system involvement, including episodic apneas, cognitive delay, seizures, and gastrointestinal complications. The most common causes of presynaptic CMS are recessive and dominant mutations in genes encoding proteins participating in the mechanisms of ACh synthesis and SV release. However, at times gene mutations can result in more complex pathogenic mechanisms. The most effective treatment of these conditions is prevention of potentially fatal episodes of apnea and other respiratory complications resulting from bulbar weakness. Pharmacologic treatments are also useful; however, in many cases the response is incomplete, and in other mild cases there is improvement with age that obviates the need for pharmacologic interventions. Preclinical studies in animal models of presynaptic CMS using targeted gene therapies are promising but these new therapies will not be available in the near future.",
        "42404894": "ID: 42404894\nTitle: FcRn antagonist and C5 complement inhibitor as early rescue strategies in severe Myasthenia Gravis: a two-case report.\nAbstract: Myasthenia gravis (MG) is an autoimmune neuromuscular disorder in which approximately 10-15% of patients with generalized AChR antibody-positive MG develop refractoriness to standard immunosuppressive therapies. Advanced therapeutic strategies, including FcRn antagonists and C5 complement inhibitors, have demonstrated early and sustained clinical efficacy in pivotal phase 3 trials. However, evidence supporting their early use in complex clinical scenarios remains limited. We report two cases of severe generalized MG in which early initiation of advanced therapies was associated with rapid clinical stabilization. In the first case, a 75-year-old man with thymoma-associated MG and severe bulbar involvement refractory (MG-ADL: 11) to plasma exchange (PLEX) and intravenous immunoglobulins (IVIg), and unable to continue azathioprine due to adverse events, received off-label efgartigimod preoperatively. Near-complete resolution of bulbar symptoms was observed within 48 hours, enabling robot-assisted thymectomy on day 4 following the first infusion, with sustained neurological improvement at one-month follow-up (MG-ADL score: 2). In the second case, a 74-year-old man with severe refractory bulbar MG requiring nasogastric tube feeding (MG-ADL: 13) and subsequent percutaneous endoscopic gastrostomy (PEG) was treated with ravulizumab after an incomplete response to PLEX, IVIg, corticosteroids, and azathioprine. MG-ADL decreased from 9 at treatment initiation to 5 after two infusions of ravulizumab, and complete recovery of swallowing function allowed PEG removal at 18-week follow-up, with achievement of minimal symptom expression (MG-ADL score: 0). These cases highlight the potential role of early and targeted use of advanced immunotherapies in severe, refractory MG, including as a bridging strategy to thymectomy. Further prospective studies are needed to define optimal criteria and timing for early integration of these agents into the therapeutic algorithm.",

In children, it typically follows infection, but association with malaria is rare. We report a four\u2011year\u2011old Lebanese girl living in Nigeria, who developed progressive weakness, dysphagia, inspiratory stridor, and gait ataxia 2\u00a0weeks after treatment for Plasmodium falciparum malaria. Neurological examination revealed lower\u2011extremity weakness with areflexia, bulbar involvement causing stridor, unilateral facial weakness, and gait ataxia (Hughes score 4). Cerebrospinal fluid analysis showed albumin\u2011cytologic dissociation, and nerve conduction studies demonstrated acute inflammatory demyelinating polyradiculoneuropathy. Given the rapid progression and severity, therapeutic plasma exchange (PE) was administered (five exchanges over 10\u00a0days) along with supportive care. Strength improved steadily, and at 1\u00a0month she was able to walk and run independently (Hughes score 0). This case expands the limited pediatric literature on malaria-associated GBS and highlights the importance of recognizing evolving bulbar and neurological symptoms after Plasmodium falciparum infection. Early supportive care and immunotherapy may contribute to favorable neurological recovery.",

        "42433772": "ID: 42433772\nTitle: Acute quadriparesis revealing Gitelman syndrome: a case report.\nAbstract: Gitelman syndrome (GS) is a rare autosomal recessive renal tubulopathy caused by SLC12A3 gene mutations, leading to hypokalemia, metabolic alkalosis, hypomagnesemia, and hypocalciuria. Its estimated prevalence ranges from 1 to 10 per 40\u00a0000 individuals worldwide, with a carrier frequency approaching 1%, underscoring its potential public health relevance despite underdiagnosis. This case highlights a rare presentation of GS with acute quadriparesis mimicking neurological emergencies, emphasizing the risk of misdiagnosis in acute care settings. A 30-year-old female presented with acute-onset fever, vomiting, and progressive quadriparesis. Examination revealed flaccid paralysis (power: 2/5), areflexia, and bulbar weakness. Critical biochemical findings included severe hypokalemia (K+:\u00a01.6\u00a0mmol/l), hypomagnesemia (1.19 mg/dl), metabolic alkalosis (pH: 7.48, HCO3 -: 32 mEq/l), hypocalciuria (6.43 mg/24\u00a0h), low urinary potassium, and elevated serum renin. This case demonstrates an intercurrent illness that precipitated acute decompensation in previously undiagnosed GS, leading to profound weakness mimicking Guillain-Barr\u00e9 syndrome, periodic paralysis and Bartter syndrome. The key to diagnosis lies in recognizing the distinctive biochemical triad of hypokalemia, hypomagnesemia, and hypocalciuria with renal potassium wasting. Although genetic testing for SLC12A3 mutations remains the diagnostic gold standard, it is often unavailable in resource-limited settings, making biochemical recognition crucial. GS is a great mimicker that can present with acute severe paralysis. Clinicians must include it in the differential for unexplained hypokalemia and metabolic alkalosis, as prompt recognition and management with magnesium and potassium supplementation are crucial to prevent life-threatening arrhythmias, recurrent paralysis and reduce long-term morbidity.",
        "42437610": "ID: 42437610\nTitle: Vestibular syndrome associated with subcutaneous hemangiosarcoma in a cat.\nAbstract: Hemangiosarcomas (HSAs) are rare neoplasms in cats, with cutaneous and subcutaneous forms occurring more frequently than visceral HSAs and often associated with chronic ultraviolet radiation exposure. Herein, we report a case of vestibular syndrome secondary to subcutaneous hemangiosarcoma in a 2-year-old cat. The patient was presented with ataxia, proprioceptive deficits, cranial nerve palsy, mild nystagmus, and head tilt. The cat tested positive for feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV), while complete blood count, serum biochemical profile, and albumin-to-globulin ratio were within normal limits. Based on the neurological findings and the absence of systemic abnormalities, central vestibulopathy was suspected. Corticosteroid therapy resulted in transient clinical improvement within 36 hours; however, 48 hours later, the cat developed vocalization and reduced consciousness. Due to the poor prognosis, euthanasia was elected. Necropsy revealed two dark-red subcutaneous nodules (\u223c1 cm) in the right thoracic region, multifocal omental nodules, and a red mass (3.2 \u00d7 2.7 \u00d7 1.3 cm) compressing and replacing part of the cerebellar parenchyma. Histopathologically, all nodules consisted of proliferating neoplastic endothelial cells forming irregular vascular channels filled with erythrocytes, consistent with hemangiosarcoma. Cerebellar metastasis accounted for the clinical signs of central vestibulopathy. Although meningoencephalitis is the most common cause of central vestibular disease in cats, neoplasms involving the cerebellum or brainstem should also be considered as differential diagnoses.",
        "42444959": "ID: 42444959\nTitle: The role of radiologic assessment in evaluating and monitoring respiratory function in amyotrophic lateral sclerosis (ALS) patients: a narrative review.\nAbstract: Respiratory failure is the primary cause of mortality in amyotrophic lateral sclerosis (ALS), usually caused by progressive neuromuscular respiratory weakness. Standard pulmonary function tests (PFTs) such as maximal inspiratory pressure (MIP), maximal expiratory pressure (MEP), and both supine and upright forced vital capacity (FVC) are crucial for objective measurements of diaphragmatic weakness but have limitations, including dependence on the patient's performance and the inability to detect early, subclinical diaphragmatic impairment or be used effectively in patients with bulbar symptoms. Radiological assessments, particularly dynamic imaging, have emerged as potential objective tools for evaluating respiratory function. This review comprehensively summarizes findings on the use of diaphragmatic ultrasound (DUS), dynamic chest magnetic resonance imaging (MRI) and deep learning (DL)-based chest computed tomography (CT) for assessing lung function in ALS patients. Key radiological metrics include diaphragm thickness (DT), thickening fraction during inspiration, real-time diaphragmatic excursion, lung diameter changes and changes in pulmonary length and area. These measures have been compared with conventional PFTs in various studies to validate their use for diagnostic accuracy, particularly in early stages of disease. DUS is a non-invasive, widely available tool that strongly correlates with PFT measurements, especially FVC, MIP, and sniff nasal inspiratory pressure (SNIP). Dynamic measures, such as excursion and velocity, appear more sensitive to early dysfunction than thickness alone. Chest dynamic MRI has also shown significant correlations with spirometric parameters. Small cohort studies indicate that dynamic chest MRI is a superior, sensitive tool for detecting early respiratory impairment in asymptomatic patients with normal spirometry. Radiological assessments, primarily DUS, DL-based chest CT and dynamic MRI, offer valuable, objective, and non-invasive methods for monitoring respiratory muscle strength in ALS. These techniques serve as complementary tools to traditional PFTs, particularly in selected clinical scenarios such ALS patients with early disease, bulbar involvement and unable to perform PFTs. Further longitudinal research with larger cohorts is needed to standardize protocols and validate their role as early parameters to guide the timely initiation of supportive interventions like non-invasive ventilation (NIV).",
        "42447075": "ID: 42447075\nTitle: Single-Dose Nivolumab as a Trigger of Myocarditis, Myositis, and Myasthenia Gravis Overlap Syndrome With Late Cardiac Death Despite Initial Recovery: A Case Report.\nAbstract: BACKGROUND Immune checkpoint inhibitors (ICIs) have transformed the treatment of advanced malignancies but can cause life-threatening immune-related adverse events. Myocarditis, myositis, and myasthenia gravis (MMM) overlap syndrome is a rare, highly morbid complication with high mortality. Most cases develop early in therapy, sometimes after a single dose. CASE REPORT A 73-year-old man with resected stage IIIC malignant melanoma presented 4 weeks after his first dose of adjuvant nivolumab with progressive weakness, gait instability, dyspnea, and dark-colored urine. Workup revealed markedly elevated troponin (11 162 ng/L), creatine kinase (5518 IU/L), and transaminases (aspartate transaminase 614 IU/L, alanine transaminase 497 IU/L), with new right bundle branch block on electrocardiography. ICI-associated myocarditis, myositis, and hepatitis were diagnosed; high-dose intravenous methylprednisolone was initiated. He subsequently developed diplopia, ptosis, bulbar weakness, and respiratory compromise from myasthenia gravis, prompting plasmapheresis and pyridostigmine. He improved with escalating immunosuppression and was discharged on oral prednisone and pyridostigmine after 16 days. Nivolumab was permanently discontinued. Two and a half weeks later, he had a fatal out-of-hospital cardiac arrest. CONCLUSIONS This case illustrates the severe and unpredictable course of MMM overlap syndrome after a single dose of nivolumab. Despite early aggressive immunosuppression and apparent recovery, the patient had a delayed fatal cardiac event. Given the risk of relapse during corticosteroid taper, structured post-discharge cardiac surveillance with serial troponin and ambulatory rhythm monitoring may help detect subclinical activity or arrhythmia. Prospective studies are needed to define optimal monitoring and identify predictors of late mortality.",

We also explored whether the combination of serum neurofilament light chain (NfL) levels and CST subfiber abnormalities may provide better diagnostic performance in differentiating prediagnostic ALS patients from disease controls (DCs) and healthy controls (HCs) than single markers. In this retrospective study, prediagnostic ALS was used as an operational term for patients who presented at baseline with chronic progressive limb weakness or bulbar symptoms, had no clinically evident typical UMN signs, and were subsequently confirmed to have sporadic ALS according to the Awaji criteria during longitudinal follow-up. Patients whose final diagnosis was not ALS after follow-up were classified as disease controls. Probabilistic tractography was performed on baseline MRI data to assess CST subfiber damage in 47 ALS patients, 20 DCs, and 51 HCs. Compared with Controls, ALS patients had significantly lower neurite density index (NDI) values of CST subfibers, particularly those originating from the primary and supplementary motor cortex. The diagnostic performance of the combined model incorporating serum NfL and CST subfiber NDI values in differentiating prediagnostic ALS patients from HCs and DCs was 0.925 and 0.928, respectively, which was better than that of single markers (0.634-0.886 and 0.699-0.856, respectively). Our findings suggest that CST subfibers NDI values are promising neuroimaging markers for detecting in\u00a0vivo UMN degeneration in prediagnostic ALS. Moreover, combining blood and neuroimaging markers may further improve early diagnostic performance.",
        "42476408": "ID: 42476408\nTitle: Overcoming Age Barriers: Endoscopic Endonasal Management of Pituitary Apoplexy in Elderly Patients - A Single Center Experience and Literature Review.\nAbstract: Pituitary apoplexy (PA) is an acute hemorrhagic event within the pituitary gland, most often occurring in pre-existing adenomas. In elderly patients, management is challenging due to frailty, comorbidities, and variable presentation. This study aimed to evaluate clinical features, management, and outcomes of PA in the elderly. We performed a retrospective analysis of elderly patients (\u226565 years) treated for PA at a tertiary referral center in Italy between 2011 and 2022. Data included demographics, clinical presentation, endocrine status, tumor characteristics, frailty (mFI-5), management, and outcomes. Twenty-eight patients (median age 71 years; 79% male) were included. Visual disturbances occurred in 61%, cranial nerve palsy in 71%, and hypopituitarism in 43%. Median mFI-5 was 1. Steroids were administered in 61% of cases. At follow-up, pituitary function did not recover in patients with preoperative hypopituitarism and worsened in 11%, with 10% developing panhypopituitarism. Postoperative hypothyroidism occurred in 54%. Higher frailty showed a non-significant trend toward worse cranial nerve and endocrine outcomes. Steroid therapy was significantly associated with visual improvement (OR 47.1, p = 0.04). PA in the elderly shows heterogeneous presentation and significant endocrine morbidity. Early diagnosis and prompt steroid therapy are crucial. The endoscopic endonasal approach is safe and effective, but careful patient selection remains essential."
