Abstract

We have reserched the relationship of their clinical pictures and factors related to the risk of recurrence of 75 patients with simple or complex febrile convulsions, who were admitted to the Department of Pediatrics, Chungnam National University Hospital from January 1987 to July 1991. The 75 patient were followed up and consisted of the 55 patients with initial or non-recurrent febrile convulsions and the others 20 patients with recurrent febrile convulsions. The results were of follows: 1) The age of first episodes was under the 6 years in 94.6% and the first episode under the 12 months was 14.6% in initial cases and 55% in recurrent cases. 2) There were family history of convulsive disorder in 40% of recurrent cases, compared to 10.9% of initial cases. 3) In gestational age, there was no significant difference between initial and recurrent cases. 4) In sex distribution, the boys (66.7%) outnumbered the girls (33.7%) and the ratios was 2:1. Among the recurrent cases of 20 patients, the boys (90%) were much more than the girls (10%). 5) The patients of low birth weight had more febrile convulsions than large birth weight in both initial and recurrent cases. 6) There was no significant difference between initial and recurrent cases in the causes of febrile convulsion. 7) In abnormal EEG findings, recurrent cases were 30% more than 7.3% of initial cases. 8) There was no significant difference of number of seizure during a day in both initial and recurrent cases. 9) In episodes of duration over 15 minutes, recurrent cases were 40% more than 23.7% of initial cases. 10) The resident of urban was 78.6% and of rural was 21.4%. 11) The types of convulsion were generalized in 92% of total cases and focalized in 8%. In the focal types, recurrent cases (15%) were much more than initial cases (5.5%). 12) In occurrence of seizures in body temperature above 40캜, it was 5.5% in initial cases, whereas it was 20% in recurrent cases. 13) There was no significant difference between initial and recurrent cases on fever duration before seizure.
