Abstract

The aim of this study was to evaluate the risk factors of recurrences after their first febrile convulsions in infants and young children. Dlinical studies were made on 187 cases of febrile convulsions who were admitted to the department of pediatrics of Wallace Memorial Baptist Hospital from March, 1990 to December, 1992 1) 63 cases of 187 cases had recurrences after their febrile convulsions. Thus, the recurrence rate was 33.7% 2) The male to female ratio was 2.1:1. And there were no significant differences in recurrence rates between sexes. 3) The recurrence rate was significantly higher in those whose initial febrile convulsions were developed before first 18 months of life than those whose initial convulsions were after 18 months of age (49.3% vs. 12.5%) 4) The time interval from initial attack to recurrence was within 12 months in 80% of cases. 5) Our study revealed that the seizure characteristics of he initial febrile convulsion are not important as predictive factors about the probability of recurrences. 6) Among the total 187 cases, family history were present in 52 cases (27.8%). And there were significantly higher recurrence rates if their families show the same history of febrile convulsion (63.5% vs. 22.2%) 7) The risk of recurrence was much higher in patients whose first febrile history of febrile convulsion at the same time.
