[Kawasaki disease in Mexico: an analysis of 13 cases].

Thirteen clinical charts belonging to children with Kawasaki disease admitted to different hospitals were analyzed. The average age among the children was three years (from nine months to nine years), with a predominance of this disease in males with a ratio of 3.3:1. Echocardiograms were obtained from 10 of the patients; seven showed coronary aneurysms (70%). Other complications seen were myocarditis in six children, and one case in each of the following: arthritis, pericarditis, cardiac failure, coronary thrombosis, hydropic gall bladder and aseptic meningitis. All of the patients recovered successfully; only four of the patients with aneurysms were followed-up with an echocardiogram. The echocardiogram showed the aneurysms to have disappeared in three of the children one to five months later, and the other showed a persistent aneurysm plus dilated myocardiopathy 2.5 years later in the remaining patient. It is worth noting the high incidence of aneurysms (70%) compared to other series (20-65%) which may be due to the suspicion of this diagnosis in only typical cases.
