Survey of Harada Scoring of Occurrence of Coronary Aneurysm in Kawasaki Disease Compared to Current Criteria
Chang Kyu Nam, Yong Wook Kim, Ki Bok Kim
J Korean Pediatr Soc. 1999;42(7):928-935.   Published online July 15, 1999
Purpose : Gamma-globulin is effective in preventing coronary aneurysm, the primary complication of Kawasaki disease(KD). However, in order to predict high-risk cases which absolutely require γ-globulin, because of its high expenses, Harada score(HS) was introduced in Japan in 1990. We attempted to compare HS scoring with the health insurance criteria currently used in Korea. Methods : Retrospective studies were performed on...
