Buruli ulcer: Evaluation of its medical and surgical management at the Allada (Benin) Screening and Treatment Center, 2010-2014.

The objective of our study was to evaluate the medico-surgical management of Buruli ulcer (BU) in the BU Screening and Treatment Center (CDTUB) of Allada in Benin. This retrospective and descriptive study retrospectively reviewed records of patients seen from 2010 to 2014 at the CDTUB of Allada. It included patients diagnosed with BU according to WHO epidemiological and clinical criteria as well as laboratory results and who were treated according to WHO medical and surgical recommendations. In all, 274 patients were diagnosed and treated, 57.7% of them children younger than 15 years. Ulcerative lesions (189, 69%) and WHO category II lesions (144, 52.5%) predominated. All patients received dual antibiotic therapy and 43.4% (119) underwent surgery as well. Category III lesions and multifocal lesions required more surgery, whereas most category I lesions healed under medical treatment. The overall rate of healing was 92%: 53.3% for patients who received only antibiotic therapy and 38.7% for those who also had surgery. The median healing time was 13 weeks and ranged from 4 to 56 weeks. In the CDTUB of Allada, between 2010 and 2014, most patients were treated with antibiotic therapy alone, but a significant number still received surgery.

Cutaneous basidiobolomycosis: Seven cases in southern Benin.

BACKGROUND: Cutaneous basidiobolomycosis is the most common form of entomophthoramycosis. Herein we report seven cases of cutaneous basidiobolomycosis. PATIENTS AND METHODS: A retrospective observational study was conducted at the Buruli ulcer treatment centre in Pobè and at the national teaching hospital in Cotonou from 2010 to 2015. RESULTS: Seven cases of cutaneous basidiobolomycosis were diagnosed. The mean patient age was 9.53 years. There were 4 female and 3 male patients, all from southeast Benin. Clinically, the disease presented in all cases as a hard, well-defined, subcutaneous plaque with little inflammation, and which could easily be lifted from the deep structures but remained attached to the surface structures. The overlying skin was hyperpigmented. Plaques were localized to the buttocks or thighs. All patients had inflammatory anaemia with an accelerated erythrocyte sedimentation rate (30 to 70mm over the first hour), and a low haemoglobin count (8.7 to 11.4g/dL). Blood hypereosinophilia (650 to 3784elements/mm3) was present in six of the seven subjects. Histopathology (performed for 5 of the 7 subjects) showed granulomatous lesions with foreign-body giant cells, and inflammatory cells, with occasional eosinophils surrounding fungal hyphae (Splendore-Hoeppli phenomenon). Mycological analysis revealed Basidiobolus ranarum in three cases. The patients were treated with ketoconazole (5/7) and itraconazole (2/7), with good outcomes after 10 to 24 weeks of therapy. DISCUSSION: Cutaneous basidiobolomycosis is uncommon in southern Benin, with only seven cases being diagnosed over 6 years. The diagnosis of cutaneous basidiobolomycosis is a challenge in the field in Benin due to the non-specific clinical presentation, the lack of technical resources, and the existence of numerous differential diagnoses. CONCLUSION: Cutaneous basidiobolomycosis is an uncommon fungal infection in southern Benin chiefly affecting children.

[Epidemiological and clinical characteristics of anogenital dermatoses in the department of dermatology-venereology in Cotonou, Benin]. / Profil épidémioclinique des dermatoses anogénitales dans un service de dermatologie à Cotonou (Bénin).

OBJECTIVE: The aim of this study was to document the epidemiological and clinical characteristics of anogenital dermatoses (AGDs) in Cotonou, Benin. METHOD: This retrospective, descriptive study, conducted in the Department of Dermatology-Venereology at the National University Hospital of Cotonou, examined medical records of admissions and outpatient consultations for the 5-year period 2005-2009 and included the records of all patients with a clinical diagnosis of AGD. RESULTS: The prevalence of AGD in our series was 2.6% and the prevalence of sexually transmitted AGDs (STIs) was 1.3%. The sex ratio (M:F) was 2.5, and the patients' average age was 31.1 years. AGDs were classified as infectious (77%), inflammatory (12.6%), non-infectious tumors (3.7%), physiological (2.1%), psychodermatoses (2.1%), non-infectious ulcers (1.6%), and dyschromia (1%). STIs accounted for 44% of the AGDs: condyloma (65.5%), genital herpes (19%), urethritis (8.3%), and chancroids (4.8%). The primary sites in men were the foreskin, the groin, the scrotum, and the glans, and in women, the labia majora, the groin, the labia minora, and the anal cleft. CONCLUSION: AGDs were relatively rare in hospital consultations in Cotonou. They were mainly infectious (viral or fungal), and nearly half were STIs.

[Mucocutaneous manifestations of human immunodeficiency virus infection in Cotonou, Benin]. / Manifestations cutanéo-muqueuses des personnes vivant avec le virus de l'immunodéficience humaine à Cotonou, Bénin.

The purpose of this study was to describe mucocutaneous manifestations observed in persons living with human immunodeficiency virus (PLHIV) in Cotonou, Benin. A transverse retrospective study was carried out on the records of PLHIV who underwent follow-up at the Military Teaching Hospital in Cotonou from February 2002 to September 2005. The files of all eligible adult patients examined by dermatologists prior to initiation of antiretroviral treatment were reviewed. Dermatologic manifestations were defined as any cutaneous or cicatricial lesion of the skin. Data was analyzed using the EPI INFO software package. (version 6.0). A total of 152 patient files were included. The sex ratio was 1.10 with a female predominance. Mean age was 37.8 years. HIV1 was predominant (98%). Two-thirds of patients were as stage 3 according to the WHO classification. A total of 276 dermatologic manifestations were identified. The most common manifestations were buccopharyngeal candidiasis (24.6%), prurigo (20.6%), shingles (11.6%), and dermatophytosis (10.5%). The mean CD4 lymphocyte level was 106 cells/mm3. The CD4 level was below 100 cells/mm3 in 52% of cases involving candidiasis and 60% of cases involving prurigo. Dermatologic findings in this study were identical to those described in most studies from Africa and Asia. However the low prevalence of Koposi's sarcoma and seborrheic dermitits was surprising given the advanced stage of immunodepression in our patients. The most frequent mucocutaneous manifestations of HIV infection in Benin are infectious disease and prurigo.

[Gangrene with pyocyanic infection and osteitis in a patient presenting endemic Kaposi's sarcoma: case report from Benin]. / Gangrène à pyocyanique et ostéite sur maladie de kaposi endémique: une observation au Bénin.

Infectious complications involving chronic skin ulcers have been well document but superinfection of ulcerated Kaposi's sarcoma nodules by multiresistant germs has rarely been reported. The purpose of this report is to describe a case in a 57-year-old HIV-negative black African man. Kaposi's sarcoma nodules appeared suddenly and spread rapidly on the right leg with pain and fever. Onset was associated with a laboratory-documented inflammatory syndrome and two metatarsal bone defects. Amputation of the leg was required due to the presence of multiresistant germs: Pseudomonas aeruginosa, multiresistant Staphylococus aureus and Candida albicans. Occurrence of bone lesions beneath superinfected Kaposi's sarcoma nodules poses a challenge for differential diagnosis of the underlying cause, i.e. either Kaposi's sarcoma or infectious osteitis. Since etiologic diagnosis of bone defects requires facilities that are rarely available in an African hospital, surgical treatment is the only alternative if antimicrobial therapy fails.
