The authors present Japanese siblings of a 6-year-old girl and a 4-year-old boy, who concurrently experienced convulsions with mild gastroenteritis. These siblings, their father and paternal grandfather had afebrile seizures that intermittently occurred without symptoms of gastroenteritis and terminated within a few days at their infancy. An underlying genetic factor might not only cause benign familial infantile seizures but it might also confer the susceptibility to the convulsions with mild gastroenteritis in these siblings.

Pregabalin (Lyrica) is a novel amino acid compound that binds with high affinity to the alpha2-delta (alpha2-delta) auxiliary protein of voltage-gated calcium channels. In vivo, it potently prevents seizures, pain-related behaviors and has anxiolytic-like activity in rodent models. The present studies were performed to determine the profile of pregabalin anticonvulsant activity in a variety of mouse and rat models. ⋯ Pregabalin caused ataxia and decreased spontaneous locomotor activity at dosages 10-30-fold higher than those active to prevent seizures. These findings suggest that pregabalin has an anticonvulsant mechanism different from the prototype antiepileptic drugs and similar to that of gabapentin except with increased potency and bioavailability. In summary, our results show that pregabalin has several properties that favor treatment of partial seizures in humans.
