Few studies have been conducted on the epidemiology in pregnancy in sub-Saharan Africa. This study aimed to improve the care of pregnant women infected with hepatitis B virus (VHB) and their newborns in the urban district health. Method: This study was conducted from 01/09/2014 to 01/09/2015. Study involved three types of data collection: a collection of data from health facilities involved in the project; repeated cross-sectional survey among health personnel; a prospective study of pregnant women identified positive for HBsAg and followed at the University Hospital Yalgado Ouédraogo (CHU-YO). Knowledge assessment was made among health staff and pregnant women using a knowledge score. Construction of the score came after a factorial analysis of multiple correspondences on population health workers surveyed in the first round (N = 119) on one hand and all pregnant women (N = 266) on the other hand. This had identified among the 79/19 questions, those that discriminated best knowledge of paramedics and pregnant women. For pregnant women, this score was then dichotomized from the center and logistic regression was performed to determine the sociodemographic, medical and obstetric characteristics that influenced it (p value < 005). Results: Health staff had been surveyed twice (N = 119/100). In general, the level of knowledge was good on targeted knowledge, both before and after training. No health worker routinely offered screening for hepatitis B among pregnant women attending antenatal clinics. Altogether 266 pregnant women HBsAg-positive were referred and followed CHU-YO. Half of the patients had a score lower than 2/17. Univariate analysis showed that variables such as education level influenced significantly the level of knowledge. Women with

Background: Preschool children are a vulnerable to skin diseases. However, the epidemiological and clinical profil of these conditions is little studied in this population in Burkina Faso. The purpose of this work was to study the skin conditions for preschool children in the city of Ouagadougou. Patients et Methods: We conducted a descriptive cross-sectional study from March to June 2017, including children aged 2-6 years, regularly enrolled in a public or private nursery school. We conducted two stages cluster sampling from the list of 23 public awakening and preschool education centers and the 359 deprived of the city of Ouagadougou. The minimum sample size was calculated to 2 234 children with Swartzch formula. Epidemiological, clinical and therapeutic variables were sought. Results: Out of 2 342 examined children, 792 were presenting a dermatoses, that is a frequency of 33.8 percent. Boys accounted for 50.9 percent. The average age was 4 years. Infectious skin diseases accounted for 33.3%, and the inflammatory 18.4%. The most frequent infectious dermatoses were the folliculitis/boils (18.5%), ringworm (7.6%) and dermatophytie of the glabrous skin (2.3%). Inflammatory and immuno-allergic dermatoses were the sweating Miliaria (17.9%), Seborrheic Dermatitis (2.1%) and prurigo (2%). Genodermatoses and malformations were the naevi (9.6%), angioma (0.5%) and lichen striatus (0.5%). Parents were unaware the existence of their children dermatosis in 95.4% of the cases. Only 36 children had consulted a health officer before the investigation, most often after a traditional treatment failure. No school had an infirmary. Conclusion: dermatological disorders are common in preschool. Also, they are ignored or trivialized by parents and teachers. Awareness campaigns, would allow a screening and early treatment of these conditions.

Introduction: L'histoplasmose à Histoplasma capsulatum var. duboisii est une affection rare en Afrique. Les lésions cutanées localisées sont les plus fréquentes. Nous rapportons une forme disséminée chez un enfant immunocompétent. Observation: Une élève de 8 ans est hospitalisée pour des nodules cutanés, généralisés, associés à des douleurs ostéo-articulaires très intenses de la quasi-totalité des articulations. L'examen a noté une malnutrition aiguë modérée, des nodules sous cutanés, multiples, des papules rosées, à surface plane, des papules ombiliquées, des tuméfactions nodulaires très douloureuses de plusieurs articulations, de multiples adénopathies fermes, mobiles, une atteinte osseuse multiple à la radiographie, une hépatosplénomégalie et des ulcérations secondaires douloureuses. L'histologie d'un nodule cutané et d'une papule ombiliquée a mis en évidence H.capsulatum var. duboisii. Après l'échec d'un traitement au fluconazole, l'évolution a été favorable sous l'amphotéricine B. La patiente a bénéficié de la collaboration Nord-Sud et de l'aide des structures sociales. Conclusion: Cette observation nous a permis de décrire les particularités cliniques et socio-économiques, les difficultés diagnostiques et thérapeutiques d'un cas d'histoplasmose africaine disséminée et de démontrer encore l'efficacité de l'amphotéricine B.
