DescriptionLa chorée fait partie des syndromes hyperkinétiques des mouvements anormaux avec une prévalence de 5% de tous les mouvements anormaux. Les étiologies sont multiples et dominées par la chorée de Sydenham dans les pays sous-développés.ObjectifL’objectif de notre étude était de caractériser les aspects épidémiologiques, cliniques, paracliniques, étiologiques, thérapeutiques et évolutifs des enfants suivis pour chorée de Sydenham à l’unité neuropédiatrique du centre hospitalier national d’enfant Albert Royer.Patients et méthodesIl s’agissait d’une étude rétrospective et descriptive allant de janvier 2005 à janvier 2019 qui s’est déroulée à l’unité de neurologie pédiatrique du Centre National Hospitalier d’Enfants Albert Royer (CNHEAR) chez les enfants diagnostiqués de chorée de Sydenham et dont l’âge était inférieur ou égal à 16 ans.RésultatsEn 14 ans, nous avons colligé 11 enfants diagnostiqués de chorée de Sydenham dont 8 filles. L’âge moyen des enfants était de 9,45 ans. Les signes extra neurologiques étaient les cardiopathies rhumatismales et les arthralgies. Tous les patients ont bénéficié de neuroleptique (halopéridol) et l’évolution était favorable chez 90,90% des enfants.ConclusionLes chorées représentent une symptomatologie peu fréquente dans notre contexte. La chorée de Sydenham est la forme la plus représentée des chorées aigues infectieuses de l’enfant. Le traitement par l’halopéridol garde toute son efficacité dans le traitement symptomatique de ces chorées. DescriptionChorea is one of the hyperkinetic abnormal movements’ syndromes with a prevalence of 5% of all abnormal movements. The etiologies are multiple and dominated by Sydenham’s chorea in underdeveloped countries.PurposeThe objective of our study was to characterize the epidemiological, clinical, paraclinical, etiological, therapeutic and evolutionary aspects of children followed for Sydenham’s chorea at the pediatric neurology unit of the Albert Royer National Children’s Hospital.Patients and methodsThis was a retrospective and descriptive study from January 2005 to January 2019 which took place at the pediatric neurology unit of the Albert Royer National Children’s Hospital in children diagnosed with Sydenham’s chorea and whose age was less than or equal to 16 years.ResultsWithin 14 years, we have collected 11 children diagnosed with Sydenham’s chorea including 8 girls and an average age of 9.45 years. The extra neurological signs were rheumatic heart disease and arthralgia. All patients received neuroleptic (haloperidol) and the outcome was favorable in 90.90% of the children.ConclusionChorea represent an uncommon symptomatology in our context Sydenham’s chorea is the most common form of acute infectious chorea in children. Treatment with haloperidol remains effective in the symptomatic treatment of these choreas.

IntroductionLa neurologie est la spécialité médicale qui étudie les maladies du système nerveux (central et périphérique). Au Sénégal, elle a été pendant longtemps cantonnée à Dakar. L’avènement de l’UFR Santé a favorisé la mise en place d’une consultation de neurologie à l’hôpital de Tivaouane depuis 2014. L’objectif de notre travail était de faire le bilan de cette activité après presque quatre ans.MéthodologieA partir du registre de consultation, nous avons collecté et analysé les données sociodémographiques et les motifs de consultation des patients entre Avril 2014 et Janvier 2018.Résultats1112 patients ont été consultés durant la période dont 59% de femmes. La tranche d’âge la plus représentative était 35-70 ans avec 47,9%. Les principaux motifs de consultation étaient représentés par les lombosciatalgies (25%), les crises comitiales (11,2%), les céphalées (9,3%), l’hémiplégie (5,5%), des paresthésies (5%), les lombalgies 2,5 %, le syndrome parkinsonien (1,8%), les cervicalgies (1,7%), les vertiges (1,3%).Discussion et conclusionNos résultats montrent donc qu’il y a une grande diversité des motifs de consultation neurologique à Tivaouane chez des patients qui, pour l’essentiel sont des adultes jeunes. Ils nous permettent aussi d’avoir, dans un premier temps, une vision panoramique des motifs de consultation et, dans un deuxième temps, d’envisager des études ciblées, notamment pour les motifs les plus fréquents comme les lombosciatalgies, les crises comitiales et les céphalées par exemple. Background and purposeNeurology is the medical specialty that studies diseases of the nervous system (central and peripheral). In Senegal, it was for a long time confined to Dakar. The advent of the UFR Santé has favored the establishment of a neurology consultation at the Tivaouane hospital since 2014. The objective of our work was to present the results of this activity after almost four years.MethodFrom the consultation register, we collected and analyzed the socio-demographic data and the reasons for consulting patients between April 2014 and January 2018. 1112 patients were consulted during the period, 59% of whom were women. The most representative age group was 35-70 years old with 47.9%. The main reasons for consultation were represented by lumbosciatalgia (25%), seizures (11.2%), headaches (9.3%), hemiplegia (5.5%), paresthesias (5%), low back pain 2.5%, parkinsonian syndrome (1.8%), neck pain (1.7%), dizziness (1.3%).Discussion and ConclusionOur results therefore show that there is a great diversity of reasons neurological consultation in Tivaouane for patients who, for the most part, are young adults. They also allow us to have, initially, a panoramic vision of the reasons for consultation and, secondly, to consider targeted studies, in particular for the most frequent reasons such as lumbosciatalgia, seizures and headaches for example.

Diversification of urban flora is undertaken by several municipalities in different forms around the world. This global effort also concerns senegalese municipalities and must be assessed. The objective of the work is to evaluate urban forestry in the municipality of Mbour. To do this, a floristic inventory was carried out at the level of target quarters, wooded areas, roads and technical services and data were analyzed. Results showed that concessions and wooded areas are richer than technical services and main roads. Seventy-seven plant species from concessions and wooded areas representing 37 families were identified and listed particularly in the Mimosaceae family. Along the various roads in the urban transport network, 1075 trees representing 16 species and 11 families have been registered mainly among Meliaceae. Technical services included 42 species and 295 trees: 21 species and 53 individuals in forest service, 17 and 99 in rural development divisional service (SDDR), 12 and 42 for urban service, 11 and 71 for municipality, 5 and 30 in the prefecture. Trees are present in Mbour town. Regular monitoring will allow their spatio-temporal dynamics and make necessary improvements&nbsp

Introduction:Publications on childhood strokes are relatively rare in Africa while the main etiological factors reported in the literature are present on the continent. This study aimed at defining the risk factors, clinical and paraclinical aspects of stroke in children in Dakar (Senegal).Methods:It was a restrospective multicenter study in the pediatric departments of Dakar university hospitals (Fann, Diamniadio and Albert Royer) between January 2005 and January 2020 of children aged 2 months to 18 years.Results:We collected 240 cases of stroke including 201 cases of ischemia and 39 cases of hemorrhage. The mean age was 60 months. Clinical manifestations were predominantly hemiplegia (33.33%) and signs of raised intracranial pressure (20.51%) for hemorrhagic strokes. In ischemic stroke, hemiplegia (79.60%) and seizures (18.05%) were predominant. The middle cerebral artery was the most affected (63.68%) in ischemic strokes. Supratentorial hemorrhagic attacks represented 94.8% and infratentorial attacks 5.12%. The main factors were sickle cell disease and heart diseases for ischemic strokes; vascular malformations for hemorrhagic strokes.Conclusion:Child stroke remains common in children with modifiable risk factors. The frequency of sickle cell disease and vascular malformations testify the need for multidisciplinary collaboration for better care of children.

International audience; The burden of encephalitis and its associated viral etiology is poorly described in Africa. Moreover, neurological manifestations of COVID-19 are increasingly reported in many countries, but less so in Africa. Our prospective study aimed to characterize the main viral etiologies of patients hospitalized for encephalitis in two hospitals in Dakar. From January to December 2021, all adult patients that met the inclusion criteria for clinical infectious encephalitis were enrolled. Cerebrospinal fluids, blood, and nasopharyngeal swabs were taken and tested for 27 viruses. During the study period, 122 patients were enrolled. Viral etiology was confirmed or probable in 27 patients (22.1%), with SARS-CoV-2 (n = 8), HSV-1 (n = 7), HHV-7 (n = 5), and EBV (n = 4) being the most detected viruses. Age groups 40–49 was more likely to be positive for at least one virus with an odds ratio of 7.7. The mortality was high among infected patients, with 11 (41%) deaths notified during hospitalization. Interestingly, SARS-CoV-2 was the most prevalent virus in hospitalized patients presenting with encephalitis. Our results reveal the crucial need to establish a country-wide surveillance of encephalitis in Senegal to estimate the burden of this disease in our population and implement strategies to improve care and reduce mortality.
