title: [Acute encephalic manifestations in Senegalese children with sickle cell disease].
abstract: The course of sickle cell disease (SCD) may be complicated by neurologic events, mainly bactérial meningitidis and stroke. We retrospectively studied all cases with acute encephalic manifestations (AEM) in a cohort of 461 children and adolescents with SCD followed at Albert Royer Children Hospital of Dakar (Senegal) from january 1991 to december 2000 (ten years). Among them 438 had sickle cell anemia (SCA), 19 SC disease and 4 S-beta thalassemia (3 S-beta+, 1 S-beta0). Seven patients, all with SCA, presented antecedents of AEM revealed by flacid and proportionnal hemiplegia evoking stroke. Prevalence of these AEM was 1.5 per cent among patients with SCD and 1.6 per cent among those with SCA. They were 4 girls and 3 boys (sex ratio = 0.75) aged 4 to 8.5 years when occurred the first accident. We observed no clinical or biological distinctive characteristic of SCA in these patients compared to those without crebrovascular accident. Recurrence was observed once in a boy after a 12 months interval and twice in a girl after 20 and 60 months intervals successively. No transfusionnal program was applied to prevent recurrent stroke because of insufficient conditions for long-term transfusion. Stroke appears to be rare in senegalese children with SCD. However it poses in our context the major problem of applicability of transfusionnal program which constitute the only therapy universally recognised to be effective to prevent recurrence. Nevertheless hydroxyurea could be a satisfactory alternative.
