Abnormal muscle response (AMR) is a distinctive electromyographic finding exclusively in patients with HFS. The purpose of our investigation was to determine the correlation between changes in intraoperative AMR and surgical efficacy, as well as the incidence of postoperative complications in patients with HFS after undergoing MVD.</p><p><strong>Methods: </strong>In this retrospective study, we evaluated 145 patients with HFSs treated with MVD, which was maintained for 1 year postoperatively. The subjects were divided into two groups based on the persistence or disappearance of AMR. Continuous monitoring of AMR during surgery provided data on persistence. All patients were followed up 1 day, 30 days, and 1 year after MVD. A range of potential predictive factors, such as patient demographics, symptom duration, and morphology and latency of AMR, were analyzed using binary logistic regression to assess their relationship with postoperative non-cure and delayed cure rates.</p><p><strong>Results: </strong>The 1 day postoperative cure rate was 77.9%, with a 1 year postoperative cure rate of 94.59% and 1 day postoperative relief rate of 87.6%. A marked distinction was noted between preoperative and 1 year postoperative Cohen grades (P < 0.05). Moreover, 1 day after surgery, the outcome demonstrated significant variability, as shown by the binary logistic regression model (χ² = 62.913, P < 0.05). The results suggested that factors such as age, symptom duration, disappearance of AMR, and preoperative carbamazepine treatment markedly influence outcomes 1 day after surgery. The binary logistic regression model for delayed cure at 1 year showed significant variability (χ² = 54.883, P < 0.05). Furthermore, analysis using generalized estimating equations revealed that the duration of postoperative follow-up significantly impacted Cohen grades, as did the disappearance of AMR, with the grade of AMR disappearance being only 10% of that of non-AMR disappearance (P < 0.05).</p><p><strong>Conclusion: </strong>Our findings suggest that MVD is an effective intervention for HFS. Our findings also indicate that factors such as patient age, duration of symptoms, disappearance of AMR, and preoperative carbamazepine therapy are significant predictors of 1 day postoperative cure rate.

The brain regions involved in ocular flutter have not been definitively determined. Sulfatide is an acidic glycolipid crucial for maintaining myelin sheath integrity and neuronal transmission. Antibodies against sulfatide can disrupt neuronal signals, and their formation is linked to autoimmune conditions such as Guillain–Barré syndrome and GALOP syndrome. To our knowledge, no pediatric cases of ocular flutter associated with sulfatide antibody-positive neuropathy have been reported.</p><h3>Case description</h3><p>A 15-year-old male with no medical history presented with oscillopsia and blurred vision. His prenatal, natal, and developmental history were unremarkable. Neurological examination revealed rapid, low-amplitude horizontal saccadic oscillations (ocular flutter) with no other neurological abnormalities. Extensive testing, including MRI of the brain and spine; blood tests; lumbar puncture; and screenings for viral, bacterial, and autoimmune conditions, returned normal or negative results. A high titer of anti-sulfatide IgM antibodies was detected. The patient was treated with intravenous immunoglobulin (IVIG), which led to complete resolution of ocular flutter. At the 3-month follow-up, his neurological examination was normal, and he remained asymptomatic with monthly IVIG infusions.</p><h3>Conclusion</h3><p>This is the first reported case of ocular flutter associated solely with anti-sulfatide antibody positivity. This finding underscores the importance of considering sulfatide antibody testing in atypical or treatment-resistant cases of ocular flutter. The resolution of symptoms following IVIG treatment suggests its potential effectiveness in managing sulfatide antibody-positive conditions. Further research is needed to explore the role of sulfatide antibodies in ocular flutter and the benefits of targeted immunotherapy.</p></div>","PeriodicalId":7042,"journal":{"name":"Acta neurologica Belgica","volume":"124 6","pages":"2063 - 2065"},"PeriodicalIF":2.0,"publicationDate":"2024-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142339068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
