Benign seizures associated with mild diarrhea: clinical analysis of 20 cases

Even without electrolyte imbalance, dehydration and fever, seizures are found occasionally in the cases of mild diarrhea. Such patients have shown favorable outcome during long-term follow-up. Twenty cases (10 boys and 10 girls) of benign seizure with mild diarrhea have been diagnosed at the Pediatric Department of Cathay General Hospital from January 1987 to March 1991. Ages-of-onset ranged from 3 months to 43 months (mean 19 months). Most cases were found between December and March (16 cases, 80%). Most seizure episodes were from 2 to 5 times (10 cases, 50%); the durations of seizures were mostly within a 5-minute period (16 cases, 80%). All seizures were generalized and symmetric, including tonic-clonic (13 cases, 65%), tonic (5 cases, 25%), and clonic (2 cases, 10%). Six out of 11 cases (54.5%) showed Rotazyme (Latex agglutination) positive. After six month to four year follow up, no patient had suffered any type of epilepsy, and psychomotor development was normal in all. Further discussion of clinical features is provided.
