[Fluconazole and treatment of onychomycosis. About 86 cases]. / Fluconazole et traitement des onychomycoses. A propos de 86 cas.

Systemic treatment of onychomycosis is based these last years on the new drug utilization aiming to decrease the length of the treatment and secondary effects particularly with fluconazole. The aim of our study is to determine the efficiency and the tolerance of the fluconazole (Funzol) managed to the dose of 150 mg per week in the treatment of onychomycosis. It is a multicentric and prospective study done to different department of dermatology in Tunisia. Are included adult patients with clinical and mycologic documented onychomycosis. They are treated during 12 to 24 weeks for the fingernail and 24 to 36 weeks for the toenail. The assessment of the efficiency and the tolerance of the drug was clinic and biologic. During this survey, 86 patients are included, 55 female and 31 male with mean age of 43.5 years. Onychomycosis seat to hands in 30 cases (34.8%) with a predominance of Candida species (73%), to toes in 68 cases (79%) witch due in 85% of cases to dermatophytic agent (85%). At 6 months, clinical cure rate is observed in 51% of cases. After 9 months, at the end of therapy, 84% of patients were judged clinical successes and culture was negative in 82% of cases. Some minimal secondary effects are signalled in 11% of cases to 6 weeks and 10% to 12 weeks not justifying the stop of the treatment. So this study confirms the efficiency and the good tolerance of fluconazole in the treatment of onychomycosis.

[Leg ulcer in a patient treated with hydroxyurea for polycythemia vera]. / Ulcère de jambe chez une malade traitée par hydroxyurée pour maladie de Vaquez.

INTRODUCTION: Causes of leg ulcers vary widely, although venous insufficiency and peripheral arteriopathy are most common. Ulcers are much rarer in patients treated by hydroxyurea. CASE: A 66-year-old woman who had been treated with hydroxyurea for polycythemia vera for four years came to our consultation a month after ulceration of the left lateral malleolus had begun. Symmetric peripheral pulses were present and there was no patent venous insufficiency. After two months of local symptomatic treatment, the size of the ulcer had increased. The possible involvement of hydroxyurea in the genesis and maintenance of this leg ulcer was then considered. Hydroxyurea was stopped, and the ulcer progressively grew smaller, finally healing completely two months later. DISCUSSION: We conclude that hydroxyurea was the primary cause of the malleolar ulcer, for it healed rapidly when this treatment stopped. Hydroxyurea causes cutaneous atrophy; when followed by microtrauma, associated with deterioration in DNA repair mechanisms, it may lead to the formation of persistent cutaneous ulcers. Hydroxyurea can also affect the microcirculation and induce tissular anoxia, which may also explain both the occurrence of cutaneous ulcers after microtrauma and their often painful character.

[Epidemio-clinical profile of human scabies through dermatologic consultation. Retrospective study of 1148 cases]. / Profil epidemio-clinique de la gale humaine à travers une consultation de dermatologie. Etude rétrospective à propos de 1148 cas.

We report a retrospective study of all scabies cases collected in the department of Dermatology of Charles Nicolle Hospital during a 8 year-period (1993-2000). 148 cases of scabies were collected with a mean incidence of 144 new cases/year (65-204). Diagnosis was made clinically in all cases. Parasitological exam was done in case of doubtful diagnosis. Our purpose is to try to define an epidemio-clinical profile of scabies in Tunisia and to estimate the incidence of this parasitosis through our dermatological consultation with reviewing the literature data.
