Abstract:
Objective In present study,we aimed to investigate the ictal and interictal electroencephalography (EEG) changes in patients with infantile convulsions with mild gastroenteritis,to understand the evolution of EEG and recurrence of convulsion by follow-up.Methods In this retrospective study,all patients with infantile convulsions with mild gastroenteritis visited our hospital from January 2005 to December 2009 were included,and were followed up for 3 to 7 years.All their clinical data were summarized and analyzed.Results Fist of all,we collected 128 interictal EEGs and 4 ictal (5 episodes) reports.Based on interictal EEGs,no discharge was observed in 63 subjects,and epileptic waves were discovered in other 65 patients.In most cases (48/65) epileptic waves were found to be located in the central area.For all 5 recorded ictal EEGs (2 were from same patient),epileptic waves were originated from different regions.Two months later,epileptic waves disappeared in 52/57 cases,but there were still discharge in 5 cases.Secondly,in the 103 cases who were successfully followed up,96 were seizure free,5 had recurrence during fever (3 cases) or gastroenteritis (2 cases),but remained seizure free for last 1.5 to 3.0 years.Overall,convulsion was recurred in 2 cases and finally diagnosed as epilepsy and then treated with antiepileptic drug,keeping seizure free for recent 1.5 to 2.5 years.Conclusion (1) Discharge can be found in nearly half of interictal EEGs in cases with infantile convulsion with mild gastrocnteritis,and most of them are located in central region.(2) All discharge come from local origin in ictal EEGs.(3) Seizure may recur in cases with infantile convulsion with mild gastroenteritis,especially in the presence of causative factors.Some children have risk of developing epilepsy.
