[Sydenham's chorea in children]. / Chorée de Sydenham chez l'enfant.

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. POPULATION: 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. CONCLUSION: 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.

[Cerebral hydatic cysts in children]. / Les kystes hydatiques cérébraux chez l'enfant.

BACKGROUND: Brain cysts caused by Echinococcus granulosus are rare; they occur during childhood in endemic areas. PATIENTS: Six children, aged to 8.5-years old (mean age: 5.5 years) were admitted from 1989 to 1994 because they suffered from progressive intracranial hypertension. The brain CT-scan showed typical features of supratentorial, unilocular (four cases) or multilocular (two cases) cysts. Three children had positive serological test; two had another cyst into their lung or liver and the third had generalized cysts. This last patient died post-operatively while the five others recovered after excision of cysts. CONCLUSION: Any progressive intracranial hypertension in endemic areas requires brain CT-scan that clearly identifies the cyst and its location.

[Schwartz-Jampel syndrome (osteochondromuscular dystrophy)]. / Le syndrome de Schwartz-Jampel (dystrophie ostéochondromusculaire).

BACKGROUND: Schwartz-Jampel syndrome is a rare disorder inherited as an autosomal recessive trait and characterized by growth retardation, multiple skeletal abnormalities, myotonia-like muscle disorders and unusual facies. CASE REPORTS: Case n. 1: A boy, aged 3 years 4 months, was admitted for acute respiratory disease. His main abnormalities included rigid facial expression, blepharophimosis, puckered lips, short neck, pectus carinatum, acetabular dysplasia with coxa vara, platyspondyly and marked growth retardation. There was a continuous muscle fiber activity at rest, with abnormal discharges originating in the muscle component of the neuromuscular junction. Blood investigations revealed low values of IgA. The child died at 4 years. Case n. 2: The sister of case n. 1 was examined at 14 months of age. She presented milder facies abnormalities, difficulties of gait because of stiff hips, muscular hypertrophy, coxa vara and growth retardation. X-rays showed skeletal abnormalities and the electromyogram was similar to those of her brother. She had dislocation of her optic lens. CONCLUSION: These 2 sibs have the characteristic manifestations of Schwartz-Jampel syndrome. Parental consanguinity was also present. The IgA deficiency observed in case n. 1 and the lens dislocation in case n. 2 have both been occasionally reported in this syndrome.

[Misleading forms of visceral leishmaniasis in children. Apropos of 5 cases]. / Formes trompeuses de leishmanioses viscérales de l'enfant. A propos de 5 cas.

The authors report the cases of five children in whom kala-azar was undiagnosed at first instance. In these cases, the diagnosis was misled because of incomplete features (lack of fever, splenomegaly or hypergammaglobulinemia) an associated disease (hydatic cyst of the liver) or a complication dominating the clinical pattern (septicemia, staphylococcus respiratory infection). In one case, the patient was explored in order to diagnose portal hypertension.

[Budd-Chiari syndrome in children. Apropos of 7 cases]. / Le syndrome de Budd-Chiari chez l'enfant. A propos de 7 observations.

Seven cases of Budd-Chiari syndrome are reported in children. The mode of onset was fulminant in one case with rapidly lethal liver failure, acute in 5 cases with rapid appearance of hepatomegaly and ascites and insidious in one case, with isolated hepatomegaly. Hepatomegaly, which is a constant sign, was present in the 7 patients. Ascites and collateral venous circulation were present in 6, splenomegaly in 2 and moderate jaundice in one only. Liver function tests, deeply abnormal in the patient with fulminant liver failure, was only slightly abnormal in the 6 others. Diagnosis was corroborated by ultrasonography, cavography, hepatic veins angiography and liver biopsy in 6 patients and by post mortem examination in the 7th. Etiologic investigations did not allow finding the cause of Budd-Chiari syndrome. However, this series can be distinguished by associated total villous atrophy in 3 cases, psoriasis in one, hepatitis B in one, hepatitis A and intestinal giardiasis in one. Portasystemic shunts were performed in 3 patients. One died in the immediate postoperative period, the 2 others are presently in good health with a 5 and 6 1/2 year-follow-up. One patient died rapidly from fulminant liver failure. Another, untreated, died 16 years after the onset of the disease, from an unknown cause. Two patients are lost to follow-up.

[Familial syndrome combining short stature, microcephaly, mental deficiency, seizures, hearing loss, and skin lesions. A new syndrome]. / Syndrome familial associant: nanisme, microcéphalie, oligophrénie, épilepsie, surdité et dermatose. Un nouveau syndrome.

We report the observations of three sisters with the same autosomal recessive syndrome characterized by growth retardation, microcephaly, mental deficiency, seizures, sensorineural hearing loss, and skin lesions. The congenital nature of these symptoms was confirmed by their high prevalence among other family members. This syndrome is one of the many neurocutaneous syndromes and does not seem to fit any of the previously published descriptions.
