The prognosis of convulsions during childhood shigellosis.

We examined the long-term outcome in 111 children who had convulsions during shigellosis and were followed for 3-18 years after the incident. No deaths or persistent motor deficits occurred as sequellae. Poor coordination of fine hand movements were noted in 3.3% of the 92 children who had no pre-existing neurological abnormality. Only 1 child developed epilepsy by the age of 8 years. Of the children 15.7% had recurrent febrile seizures. The only risk factor identified for febrile seizures following convulsions in shigellosis was a previous history (P less than 0.01). These observations suggest that convulsions in shigellosis have a favourable prognosis, and do not necessitate long-term follow up.
