[Cutaneous tuberculosis in Dakar: 151 cases report].

Introduction: Cutaneous tuberculosis diagnosis is difficult because of clinical polymorphism. Our goal was to study the clinical, epidemiological and evolutionary characteristics of cutaneous tuberculosis in Dakar.

Patients And Methods: We performed a retrospective study from 1972 to 2005 of the tuberculosis cutaneous cases in our department.

Ivermectin versus benzyl benzoate applied once or twice to treat human scabies in Dakar, Senegal: a randomized controlled trial.

Objective: To compare the effectiveness of oral ivermectin (IV) and two different modalities of topical benzyl benzoate (BB) for treating scabies in a community setting.

Methods: The trial included patients aged 5-65 years with scabies who attended the dermatology department at the Institut d'Hygiène Sociale in Dakar, Senegal. The randomized, open trial considered three treatments: a single application of 12.

[Skin disease in Koranic schools in Dakar (Senegal)].

The koranic schools are in poor socio-economical conditions in Dakar and skin diseases are common in these conditions. The goal of our descriptive study was to determine the prevalence of skin diseases occurring in these situations. One hundred five boys from four koranic schools of Dakar were examined.

Epidemiologic, clinical, and therapeutic features of acne in Dakar, Senegal.

Background: Acne, a chronic inflammatory dermatosis of the pilosebaceous follicle, is very widespread worldwide, affecting 75-80% of adolescents, with an impact on their quality of life. The etiologic factors are not always the same, and the treatments proposed are not always well tolerated in black individuals.

Aims: To determine how acne affects the black population in Dakar, Senegal, and to assess the results of and tolerance to treatment.

Aesthetic problems associated with the cosmetic use of bleaching products.

Background And Aim: The use of skin bleaching products for cosmetic purposes is a frequent practice (25-96%) in women from sub-Saharan Africa. The dermatologic complications associated with this practice have been comprehensively reported. The aim of this work was to study the epidemiologic, clinical, and cosmetic aspects of these complications in order to produce better therapeutic guidelines for their management.

[Occupational allergic contact dermatitis in Dakar].

Occupational dermatitis, mainly allergic contact dermatitis and skin irritations are increasing because of new allergens and diversity of the industrial procedures. In Senegal occupational contact dermatitis are currently observed and they are not declared at our social security institution. The aim of our trial was to determinate the frequency of occupational allergic contact dermatitis, the allergens responsible and the exposed occupations.

EPR and DFT studies of the structure of phosphinyl radicals complexed by a pentacarbonyl transition metal.

Paramagnetic complexes M(CO)5P(C6H5)2, with M = Cr, Mo, W, have been trapped in irradiated crystals of M(CO)5P(C6H5)3 (M = Cr, Mo, W) and M(CO)5PH(C6H5)2 (M = Cr, W) and studied by EPR. The radiolytic scission of a P-C or a P-H bond, responsible for the formation of M(CO)5P(C6H5)2, is consistent with both the number of EPR sites and the crystal structures. The g and 31P hyperfine tensors measured for M(CO)5P(C6H5)2 present some of the characteristics expected for the diphenylphosphinyl radical.

Clinical efficacy and safety of oral terbinafine in fungal mycetoma.

Objectives: An open-label study was performed to assess the efficacy and safety of terbinafine in the treatment of eumycetoma.

Methods: Single-center, open-label study, including 27 patients with signs and symptoms of eumycetoma which had developed within 5 years and was confirmed by mycological examination. The intention-to-treat population (n=23) received 500 mg of terbinafine bid for 24-48 weeks.
