A variety of clinical phenotypes have been associated with KCNQ2 mutations, making the prediction of this rare entity difficult. Herein, we report a rare KCNQ2 variant in two siblings with self-limited familial neonatal epilepsy. The siblings had tonic seizures accompanied by clonic jerks in the first few days after birth. Genetic analysis of the siblings revealed a heterozygous KCNQ2 variant: c.1589G > A; (p.Ser530Asn). The identical variant subsequently was identified in the mother. To our knowledge, this variant has not been previously reported in individuals with KCNQ2 -related disease. This is the first report that reveals c.1589G > A variant of KCNQ2 gene as a pathogenic variant in two siblings.","PeriodicalId":42559,"journal":{"name":"Journal of Pediatric Epilepsy","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80396852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

COVID-19 became a pandemic involving almost all countries, including Japan. We evaluated the tolerability and safety of coronavirus vaccines in terms of seizures in adolescents and young adults with epilepsy (AYAWE). Methods We administered a questionnaire to AYAWE who visited the pediatrics departments of Hiroshima University Hospital, Hiroshima Prefectural Hospital, and Hiroshima City Funairi Citizens Hospital in January and February 2022. Tolerability and safety after immunization were assessed. Results In total, 114 vaccinations were delivered to 57 AYAWE aged 12 to 25 years (mean, 15 ± 3.1 years). Fifty-two (91.2%) experienced more than or equal to 1 adverse event postvaccination. The most commonly reported adverse events were fever (dose 1, 33.3%; dose 2, 73.7%) and fatigue (dose 1, 24.6%; dose 2, 50.9%). The incidences of headache (5.2 vs. 21.0%, p = 0.024), fever (33.3 vs. 73.7%, p < 0.001), and fatigue (24.6 vs. 50.9%, p = 0.004) differed significantly between the first and second doses. Only 5.2% of patients experienced transient seizure worsening, and only one patient reported a change in seizure semiology. Conclusion COVID-19 vaccines were well-tolerated in our cohort. The vaccines did not affect the number or manifestations of seizures. Similar to other illnesses, vaccination for COVID-19 can be administered to AYAWE without worsening their seizures.","PeriodicalId":42559,"journal":{"name":"Journal of Pediatric Epilepsy","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82354812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ataxia and cerebellar atrophy are rarely described as components of the disease phenotype. Case Presentation We present the cases of male twins, born after normal pregnancy and delivery, both with normal neuropsychological but with delayed motor development in the first 2 years of life. Between 8 months and 9 years of age, the boys experienced generalized tonic-clonic seizures, several times per year. When 9 years old, the children suffered an increase in seizure frequency, and the family reported gradual worsening in coordination, speech, communication, and social skills. When 9 and a half years of age, the patients were admitted to the Clinic of Child Neurology for the first time. They both had coordination syndrome (intention tremor, dysmetria, dysdiadochokinesia) that had worsened compared with previous reports, and magnetic resonance imaging of the brain showed cerebellar atrophy. The genetic testing confirmed a mutation c.2617G > T, p.Gly873Cys in SCN8A gene. After adding lamotrigine to valproate and levetiracetam, and adjusting the dosage of valproate and levetiracetam, we observed good seizure control accompanied by improvement in the coordination syndrome. Conclusion The cerebellar atrophy in our patients is likely due to the underlying sodium channelopathy, as it was presented at the time of the seizure worsening, but we cannot exclude the role of the epileptic seizures as the worsening of the coordination syndrome accompanied the seizure aggravation, and the tendency toward improvement was evident after seizure control.","PeriodicalId":42559,"journal":{"name":"Journal of Pediatric Epilepsy","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83389241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the U.S. Food and Drug Administration approved perampanel (PER) for patients as young as 4 years, there are limited data on using PER in children. Objective The aim of this study was to determine the efficacy and tolerability of adjunctive PER treatment in children with refractory epilepsy (RE). Methodology This prospective intervention study was conducted in the tertiary care center, in Bengaluru, India from December 2020 to May 2022. PER was added after the failure of a minimum of two ASDs and patients with 6 months follow-up. Treatment response was classified as complete, partial, or none with ≥90, ≥50, and <50% reduction in seizure frequency, respectively. Adverse events and discontinuation data were used to assess tolerability. Results Our cohort consisted of 100 cases, a mean age of 9.3 ± 3.8 years and male:female ratio of 3:1. The predominant seizure type was generalized seizures (74%), and concomitant enzyme-inducing ASD use was noted in 27%. Structural etiology was noted in 57%. A total of 76% of participants responded to PER therapy (46% complete response and 30% partial response), while 23% showed no response and 1% discontinued the treatment. Adverse events were observed in 25% of participants (11/25 [44%] drowsiness/sedation, 10/25 [40%] behavioral problems, and 4 [16%] other side effects). Early PER add-on provided a statistically significant benefit over late PER add-on ( p = 0.01). Response to PER did not differ significantly with the type of seizure and ASD used ( p > 0.05). Conclusion Adjunctive PER therapy is safe and effective for treating children with RE. An early add-on of PER is more beneficial in controlling seizures than a late add-on.","PeriodicalId":42559,"journal":{"name":"Journal of Pediatric Epilepsy","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2023-01-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78590655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
