Neuro-Behçet (NB) African studies are mainly North African, but Sub-Saharan Africa is not to be outdone. Our aim was to describe diagnostic and therapeutic features of NB in a Senegalese series collected in Dakar. This was a descriptive and retrospective study conducted at the Neurology department of Fann Teaching Hospital in Dakar, Senegal. All patients who met the NB's diagnostic criteria were included. Sixteen patients were collected, 14 males and 2 females with an average age of 40 years [18-71]. The main neurological signs were motor deficit (13 cases), headache (10 cases), and language disorders (4 cases). Extra-neurological signs were dermatological (14 cases), ocular (2 cases), and articular (2 cases) with aseptic unilateral gonarthritis. Fever was present in 9 patients. Neurological involvement was mostly isolated parenchymal (8 cases) or mixed (6 cases). The main clinical forms of NB were rhombencephalitis (8 cases) and retrobulbar optic neuritis (4 cases). Seven patients had a cerebral angio-Behçet with cerebral venous thrombosis (3 cases), ischemic stroke (2 cases), and intracerebral hematoma (2 cases). Under prednisone (16 cases) and azathioprine (3 cases), the short-term clinical outcome was mostly favorable (14 cases) with a modified Rankin scale at 2. NB is an under-diagnosed adult male disease in Sub-Saharan Africa and further studies are needed.Les études africaines sur le neuro-Behçet (NB) sont majoritairement maghrébines, mais l'Afrique noire n'est pas en reste. L'objectif de l'étude était de décrire les particularités diagnostiques et thérapeutiques du NB dans une série sénégalaise colligée à Dakar. Il s'agit d'une étude rétrospective à visée descriptive menée à la clinique de neurologie du centre hospitalier universitaire de Fann de Dakar, au Sénégal. Tous les patients répondant aux critères diagnostiques de NB ont été inclus. Seize patients ont été colligés, 14 hommes et deux femmes avec un âge moyen de 40 ans [18–71]. Les principaux signes neurologiques étaient un déficit moteur (13 cas), des céphalées (10 cas) et un trouble du langage (4 cas). Les signes extraneurologiques étaient dermatologiques (14 cas), oculaires (2 cas) et articulaires (2 cas) à type de gonarthrite unilatérale aseptique. Une fièvre était présente chez neuf patients. L'atteinte neurologique était majoritairement parenchymateuse isolée (8 cas) ou mixte (6 cas). Les principales formes cliniques de NB étaient la rhombencéphalite (8 cas) et la névrite optique rétrobulbaire (4 cas). Sept patients avaient un angio-Behçet cérébral à type de thromboses veineuses cérébrales (3 cas), d'infarctus cérébraux (2 cas) et d'hématomes intracérébraux (2 cas). Sous prednisone (16 cas) et azathioprine (3 cas), l'évolution clinique à court terme était majoritairement favorable (14 cas) avec un score de Rankin modifié de 2 au moment de l'exeat. Le NB est une maladie de l'homme adulte sous-diagnostiquée en Afrique noire. Des études ultérieures multicentriques nationales et sous-régionales sont souhaitables.

Epilepsy is a public health problem in Senegal and Africa because of its severity and its social importance. It occurs at any age sparing no sex. It can influence sexual life and reciprocally. Our aims were to study the effects of antiepileptic drugs on the sexual lives of women with epilepsy, the influence of these drugs on pregnancy and breastfeeding.We conducted a prospective study from 1st March to 31st August 2011 in the neurological department of the Fann-Dakar teaching hospital Senegal. Only women with epilepsy were included.We collected 120 patients aged 16-64years with a mean age of 30.58years, 45% married, 44.16% were uneducated preponderant. All patients were taking antiepileptic drugs, 89.16% was alone. Fifty-five percent of our patients had epilepsy for at least 6years; 45.83% had generalized epilepsy; 44.17% of partial seizures. In our cohort, 64.16% were under phenobarbital, 69.16% had good adherence. As side effects of drugs, 90% had sexual problems. Seventy-five percent enjoyed an active sex life. A decrease in the number of sex per week for the disease [31/55=56.66%] was noted. In addition, 51.17% were using contraception, including 38.7% of oral kind and 64.86% had noticed an increase in seizure frequency during their pregnancies. Of the 74 women who had contracted a pregnancy, 41.89% had premature infants, 16.21% have made abortions and 61.17% had psychosocial life affected.People with epilepsy often experience sexual problems that may be caused by epilepsy, antiepileptic and/or reactions of the partner and the other facing the diagnosis of epilepsy.

Congenital hypomagnesemia is a rare disease, with an impact on cognitive and neurological development. We report on three familial cases of congenital hypomagnesemia, two boys and one girl who belong to the same consanguineous family. They all presented neonatal seizures and a psychomotor developmental delay. Cerebral computed tomography showed cerebral atrophy and calcifications in one case and magnetic resonance imaging found predominant cerebellar atrophy in the two other cases. All three patients also had hypocalcemia, hyperphosphoremia, and hypomagnesemia. The parathyroid hormone blood level was low in two cases and normal in the third. One 7-month old patient died. The others received a supplementation of calcium and magnesium, which normalized calcemia, phosphatemia but not magnesemia, which remained low despite high doses. They have both developed cognitive and behavioral impairments.

Cryptococcal meningitis is much less common in children than adults. The purpose of this report is to describe 3 cases of cryptococcal meningitis observed in children admitted to the Neurology Department of the Fann University Hospital Center in Dakar, Senegal between July 2003 and November 2008. There were 2 girls whose ages were 8 and 15 years and one 9-year-old boy. All 3 patients presented acute or chronic meningoencephalitis. Diagnosis was based on direct microscopic examination of India ink preparations of cerebrospinal fluid (CSF) showing Cryptococcus neoformans at direct exam. Two patients were immunocompromised including one presenting severe protein-caloric malnutrition and one infected by HIV-1. The third patient was immunocompetent. All 3 patients were treated by intravenous Fluconazole. The immunocompetent boy died after 1 month of hospitalization due to cardiovascular and respiratory insufficiency. Both girls survived with severe neurosensory sequels. Cryptococcal meningitis that is relatively frequent in adulthood may be underestimated in children and should be tested for in any children presenting meningoencephalitis of undetermined cause.

Senegal, like many African countries is facing the so-called demographic and epidemiological transition leading to the development of neurological diseases. These diseases dominated by stroke and status epilepticus are public health priorities with a high prevalence, high lethality and high cost of care. These diseases are managed at the department of neurology, Fann Teaching Hospital, Dakar-Senegal (the only one) with a 65 beds capacity. Unfortunately, access care to the clinic is lately associated with human and material resource scarcity. To improve the management of patients at the clinic, it is important to increase resources (human and material), sensitize the population on early access to health services and prevention of risk factors.

A central nervous system infection due to Morganella morganii is uncommon. We report a case diagnosed at the neurological department of Fann teaching hospital in Dakar, Senegal. A 12-year-old boy was hospitalized for acute meningoencephalitis. The CT scan was normal and the study of cerebrospinal fluid (CSF) revealed cytological and biochemical abnormalities and M. morganii. HIV and syphilitic serologies were negative and blood CD4 lymphocyte count showed 354 per mm(3). The treatment with cefotaxime associated with gentamicin for 6 weeks was successful. The outcome of infection depends on many factors such as the onset and quality of treatment, the virulence of the germ and the status of immune system.

Describe the epidemiology of stroke among patients hospitalized at the Clinic of Neurology , Fann University, Dakar-Senegal.Retrospectively, sociodemographic, medical history and clinical data were collected for patients hospitalized for stroke from January 1st 2001 to November 1st 2003 and to whom a Computed Tomography scan of the brain was done.The population of study (314 patients) had a mean age of 61.3 years (+/-13.8) and was composed of 56.1% of women. The mean time of admission was 8.4 days (+/-23.5). The leading risk factors of stroke were hypertension, history of stroke and diabetes. Ischemic stroke represented 60.2%. The occurrence of stroke was associated with coma and hypertension. The letality rate was 24.8%.It is necessary to develop and implement health education program against risk factors for the population to reduce stroke morbidity and mortality.
