[Sydenham's chorea in children].
BACKGROUND
Sydenham's chorea was the most common form of acquired chorea in childhood. Its incidence has declined since the use of antibiotics. The aim of our study was to determine the hospital incidence of this disease and to illustrate the clinical characteristics and outcome of this disease in Tunisia.


METHODS
Retrospective study of 15 cases of Sydenham's chorea, seen between 1987 and 1997.


RESULTS
Our patients (five boys and ten girls) represented 5.6 per 1000 hospitalized children. Their mean age was 10.5 years. Two patients had a history of rheumatic fever and five had a history of throat infection during the month before chorea. The onset of symptoms was acute in five cases and insidious in ten. Choreic movements were generalized but asymmetrical in 12 cases, and unilateral in three. Psychological disorders were noted in nine cases and hypotonia in six. Rheumatic carditis was found in three patients. No patient had an obvious increase in sedimentation rate, and antistreptolysin were increased in 50% of cases. All patients were given haloperidol and five steroids, 11 were given antibiotics at the attack of chorea and 13 received secondary prevention with benzathine penicillin. Initially, abnormal movements disappeared in all cases after a mean of three months. Three patients relapsed and two among them still show abnormal movements and psychological disorders after a follow-up of 3 and 3.5 years respectively.


CONCLUSIONS
Sydenham's chorea, although less frequent than previously, is not exceptional in Tunisia. Malignant forms are not observed, but two of 15 patients developed a chronic form with sequelae. No correlation is found between outcome and secondary prevention of streptococcal infections.
