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.

The purpose of this study was to determine radiographically the prevalence of periapical periodontitis in teeth restored with crown in a Senegalese population. Full mouth periapical radiographs were obtained from 208 consecutive adult patients (6234 teeth) presenting as new patients to the Dental Service of the University. The presence of crown restorations, the periapical status and technical quality of root fillings associated were evaluated. 7.69% (n = 16) of patients had at least one tooth that was crowned. The total number of crowns assessed was 0.95% (n = 59). The molars were the teeth most crowned 40.67% (n = 24) followed by anterior teeth 30.50% (n = 18) and premolars 28.81% (n = 17). All the crowned teeth had previous root canal treatment of which only 16.94% (n = 10) were acceptable. 53 % (n = 32) of the teeth had apical periodontitis (PAI2). Unacceptable root fillings were associated with a higher prevalence of periapical disease (p0.05). Crown with a post extending more than 4 millimetres from the apex were associated with more periapical lesions 64.28% (p0.05). The results indicate a low prevalence of crowned teeth, an absence of vital preparation, a high prevalence of radiographic periapical disease and unacceptable root fillings associated.
