[Care of covid-19 patients at the dermatology hospital of Bamako]. / Prise en charge des patients covid-19 a l'hopital de dermatologie de Bamako.

AIM: To assess the COVID-19 patients' treatment duration according to the place of treatment at the Dermatology Hospital of Bamako (DHB). METHODS: This was a cross-sectional study comparing the management of COVID-19 PCR-positive patients in the hospital to that of those managed at home from March 2020 to April 2021 until two consecutive negative PCR 48 hours apart. RESULTS: Among the 1109 patients, 369 were hospitalized, 497 followed at home. As of April 31, 2021, 81.2% (900/1109) of the patients recovered, 1.3% (14/1109) were transferred to another health structure, and 2.5% (28/1109) died. No statistically significant difference was observed between the mean duration of the treatment for patients treated at home (10 days) in (95% CI, 9.69-10.3) and those managed at hospital (10 days95% CI, 9.76-10.23) (Mantel-Cox test, p= 0.060). CONCLUSION: These results suggest that the place of treatment do not influence the time to recovery. This is particularly important given the current burden of COVID-19 management on the health workforce.

OBJECTIF: Evaluer la durée du traitement des patients COVID-19 selon le lieu de pris en charge à l'Hôpital de Dermatologie de Bamako (HDB). MÉTHODOLOGIE: Il s'agissait d'une étude transversale comparant la prise en charge des patients COVID-19 PCR-positifs à l'hôpital à celle à domicile de mars 2020 à avril 2021 jusqu'à l'obtention de deux tests PCR négatifs consécutifs à 48 heures d'intervalle. RÉSULTATS: Parmi les 1109 patients, 369 ont été hospitalisés, 497 suivis à domicile. Au 31 avril 2021, 81,2% (900/1109) des patients se sont rétablis, 1,3% (14/1109) ont été transférés dans une autre structure de santé et 2,5% (28/1109) sont décédés. Aucune différence statistiquement significative n'a été observée entre la durée moyenne du traitement pour les patients traités à domicile (10 jours) en (IC 95 %, 9,69-10,3) et ceux pris en charge à l'hôpital (10 jours IC 95 %, 9,76-10,23) (test de Mantel-Cox, p= 0,060). CONCLUSION: Ces résultats suggèrent que le lieu de traitement n'influence pas le temps de récupération. Ceci est particulièrement important étant donné la charge actuelle de la gestion des COVID-19 sur le personnel de santé.

[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.

[Geriatric dermatoses in patients hospitalized in the Department of Dermatology in Bamako (Mali)]. / Dermatoses gériatriques en hospitalisation dermatologique à Bamako (Mali).

INTRODUCTION: Skin diseases in the aging population vary and are a key concern for clinicians in terms of diagnosis, management and follow-up. This study aims to describe the epidemiological and clinical aspects of skin diseases among geriatric patients hospitalized in the Department of Dermatology at the National Center In Support Of Disease, Bamako. METHODS: We conducted a cross-sectional case study of patients with geriatric dermatoses hospitalized in the Department of Dermatology at the National Center In Support Of Disease from 1 January 2010 to 31 December 2014. Out of 398 patients hospitalized, 76 patients aged 60 years and over were included in the study. Data entry was accomplished using Epidata 3.1 software, while data analysis was performed using stata 14 software. RESULTS: The prevalence of skin diseases among hospitalized geriatric patients was 19.10%. The age of the patients varied from 60 to 95 years, with an average age of 68.85 years. We enrolled 29 men and 47 women, with a sex-ratio of 0,60. The main diseases reported were dermohypodermitis (44.74%), autoimmune bullous dermatitis (13.16%), toxidermia (10.53%), venous ulcers (6.58%), arterial ulcers (3.95%), malignant tumors (5.27%), diabetic wounds (3.95%). Four patients died (5,26%). CONCLUSION: This study has assessed a high prevalence of subjects aged 60 and over hospitalized in the Department of Dermatology in Bamako. Moreover, it has confirmed that dermohypodermitis are the most frequent skin diseases among geriatric patients hospitalized in Mali.

[Epidemio-clinical profile of dermatoses in children receiving dermatological consultation in the Department of Dermatology at the National Center for Disease Control in Bamako (Mali)]. / Profil épidémio-clinique des dermatoses chez les enfants vus en consultation dermatologique dans le service de dermatologie du centre national d'appui à la lutte contre la maladie à Bamako (Mali).

INTRODUCTION: Skin diseases are a major public health problem in developing countries. In common practice, children represent the most affected segment of the population. This study aims to describe the epidemiological and clinical aspects of skin diseases in children aged 0-15 years receiving dermatological consultation in the Department of Dermatology at the National Center for Disease Control in Bamako (Mali). METHODS: We conducted a cross-sectional study in the Department of Dermatology and Venereology at the National Center for Disease Control from 1 January 2009 to 31 December 2009.Out of a total of 16339 patients who had undergone a dermatological consultation 5149 children were included in the study. RESULTS: Dermatitis-frequency in hospital attending children was 31.51%. We enrolled 2838 boys (55,10%) and 2311 girls (44.90%), with a sex-ratio of 1,22. Patient age ranged from 03 days to 15 years with an average age of 8 ± 5.7 years. Infectious dermatoses accounted for 55.10% of all dermatoses, immuno-allergic dermatoses (32.5%), inflammatory dermatoses (11.85%). CONCLUSION: Our study highlights the severity of infectious and immuno-allergic pathologies and the necessity to promote simple preventive measures such as hygiene, buying a clipper for each child.

Discrepant prevalence and incidence of Leishmania infection between two neighboring villages in Central Mali based on Leishmanin skin test surveys.

UNLABELLED: Apart from a single report, the last publication of cutaneous leishmaniasis (CL) in Mali dates back more than 20 years. The absence of information on the current status of CL in Mali led us to conduct a cohort study in Kemena and Sougoula, two villages in Central Mali from which cases of CL have been recently diagnosed by Mali's reference dermatology center in Bamako. In May 2006, we determined the baseline prevalence of Leishmania infection in the two villages using the leishmanin skin test (LST). LST-negative individuals were then re-tested over two consecutive years to estimate the annual incidence of Leishmania infection. The prevalence of Leishmania infection was significantly higher in Kemena than in Sougoula (45.4% vs. 19.9%; OR: 3.36, CI: 2.66-4.18). The annual incidence of Leishmania infection was also significantly higher in Kemena (18.5% and 17% for 2007 and 2008, respectively) than in Sougoula (5.7% for both years). These data demonstrate that the risk of Leishmania infection was stable in both villages and confirm the initial observation of a significantly higher risk of infection in Kemena (OR: 3.78; CI: 2.45-6.18 in 2007; and OR: 3.36; CI: 1.95-5.8 in 2008; P<0.005). The absence of spatial clustering of LST-positive individuals in both villages indicated that transmission may be occurring anywhere within the villages. Although Kemena and Sougoula are only 5 km apart and share epidemiologic characteristics such as stable transmission and random distribution of LST-positive individuals, they differ markedly in the prevalence and annual incidence of Leishmania infection. Here we establish ongoing transmission of Leishmania in Kemena and Sougoula, Central Mali, and are currently investigating the underlying factors that may be responsible for the discrepant infection rates we observed between them.
