      Anti-glycolipid antibodies have been confirmed in approximately 50% of acute flaccid myelitis (AFM) cases and approximately 60% of GBS cases. Furthermore, in GBS, the type of anti-glycolipid antibody is associated with clinical disease type. We experienced an AFM case with multiple anti-glycolipid antibodies including confirmed anti-GM1 antibody. Although there has been no report of anti-GM1 antibody-positive AFM, the clinical findings in this case are similar to that of anti-GM1 antibody-positive GBS. This case is considered important for studying the significance of anti-glycolipid antibody in AFM and its difference from other flaccid paralysis disorders such as GBS.

      48,XXYY aneuploidy is a rare sex chromosome variation, and 15% of the affected individuals present with seizures. This study included a 14-year-old boy with 48,XXYY karyotype revealed by seizures. The child initially developed a generalized seizure during sleep at the age of 3. The seizures were well managed with the administration of sodium valproate until the age of 12 when the generalized tonic-clonic seizure occurred. His electroencephalogram revealed frequent absence seizures and continuous spikes and waves during sleep. A 48,XXYY karyotype was identified using G-banding. The seizures were resolved with the administration of ethosuximide and sodium valproate.
