[Cutaneous tuberculosis in Bamako, Mali]. / Tuberculose cutanée à Bamako, Mali.

INTRODUCTION: Tuberculosis is the most common mycobacteriosis in sub-Saharan Africa. Cutaneous tuberculosis is rare and underdiagnosed due to its clinical polymorphism and to the smallness of technical equipment. This study aims to describe the epidemiological, clinical, histopathological aspects of cutaneous tuberculosis in Bamako (Mali). METHODS: We conducted a cross-sectional descriptive study from January 1991 to December 2008. The study was performed in the Department of Dermatology at the National Center for Disease Control and in the Department of Pneumophtisiology at the Hospital of Point G. The patients with tuberculosis confirmed by histological and/or biological examination were included in the study. RESULTS: Out of 4269 patients? medical records, 61 cases of cutaneous tuberculosis were identified (1.43%). Men accounted for 59% of the cases (36 patients) and women 41% (25 cases); sex-ratio was 1.44. The age of the patients ranged from 3 months to 61 years, with an average age of 27.56 ± 36 years. The average length of follow-up was 10.9 ± 10 months. The identified clinical forms were scrofuloderma (41 cases), ulcerative form (13 cases), verrucous form (4 cases), and tuberculous Lupus (3 cases). Tuberculosis was associated with HIV in 7 cases, with leprosy in 3 cases. CONCLUSION: Cutaneous tuberculosis is underdiagnosed in Mali. Efforts are needed to improve the accessibility and the technical equipment available in the Departments, in order to conduct an extensive interdisciplinary study on this pathology.

Dermatitis of the folds in black Africans in Bamako, Mali.

Dermatitis of the folds (intertrigo) is a frequent reason for attending consultations, particularly in Africa, where the hot and humid climate constitute an aggravating factor. It is a complex pathology with multiple and intricate etiologies. The aim of this study was to describe epidemiological and etiological aspects of dermatitis of the folds in black-skinned subjects in Bamako (Mali). We conducted a transversal descriptive survey of cases of localized dermatitis of the folds of the skin in dermatology clinics in Bamako. In total, 141 cases of intertrigo were identified: 96 female subjects (68%) and 45 male subjects. The average age of patients was 30 ± 18 years (2-80 years). The majority of patients were seen between March and June; 52% of patients had already received treatment before the consultation. The lesions affected skin folds of the groin area and/or area between the buttocks in 95 patients (57.4%), and folds of the armpits and area under the breasts were affected in 46 cases (42.6%). Eczema, erythrasma, and fungal disease were the most frequently observed pathologies. Of interest to this study is the topographical approach that a dermatologist must adopt when diagnosing certain forms of dermatitis. In populations with specific cultural practices, apart from a thorough knowledge of these specific factors, treatment of these conditions requires certain harmful attitudes and behaviors to be abandoned.

Pruritus in dermatological hospital in Bamako, Mali.

Pruritus is a symptom frequently encountered in dermatology consultations. For practitioners working in a tropical environment, particularly in Africa, the diagnosis of pruritus remains a constant problem. The aim of this study was to describe the epidemioclinical aspects and the etiologies of pruritus encountered at the dermatological hospital in Bamako. We conducted a prospective survey on a cohort of patients attending the Department of Dermatology at the Centre National d'Appui (CNAM-Ex Institut Marchoux) in the Fight against Disease over a 1-year period (June 1, 2009-May 31, 2010). Consequently, the study included every patient, whatever their age and gender, that agreed to take part in the survey and whose main reason for attending for a consultation was "pruritus." The clinical and biological data were entered and analyzed using Epi Info software, version 6.04 fr. A total of 232 patients (163 women, 69 men) attended because of pruritus out of 1761 overall patients (i.e., a prevalence of 13.17%). The mean age of the patients was 33 ± 19 years. Dermatological causes represented 95% of the etiologies. This work allowed us to observe the systemic causes of pruritus in the dermatological environment in Mali and greater likelihood of black women to attend because of pruritus.

[Etiology of acquired hypochromic patches in dermatological area in Mali]. / Etiologies Des Hypochromies Acquises En Milieu Dermatologique.

INTRODUCTION: In dark skin patients, hypopigmentation is the most disfiguring condition. Very few studies on hypochromic disorders have been conducted in specialized health centers. The present study is aimed to describe the etiologies of hypochromic patches in dermatological area, in Bamako. METHODS: We carried out a cross sectional study in the Dermatology Clinic of the "Centre National d'Appui à la lutte contre la Maladie (CNAM, Ex Institut Marchoux)". All acquired hypochromic patches (HP) were selected. HP was defined as a "skin patch lighter in pigmentation than normal surrounding skin with a diameter of at least 1 cm". The diagnosis was mainly based on clinical findings. RESULTS: The prevalence of HP was 3.42% and the main causes were seborrheic dermatitis (23.3%), pytiriasis alba (20.15%), vitiligo (18.9%), pityriasis versicolore (18.5%) and leprosy (12.6%). CONCLUSION: There are many causes of HP including leprosy, a disease though rare to date, but still prevalent in dermatological area.

Etiologies des hypochromies acquises en milieu dermatologique

Introduction : Parmi les troubles pigmentaires rencontres chez les sujets a peau noire; l'hypochromie encore appelee tache claire est sans doute la plus affichante. Peu d'etudes ont ete effectues en milieu specialise. Le but de ce travail est d'etudier les etiologies hypochromies en milieu dermatologique a Bamako.
