[Notes on dermatosis in the Lao People's Democratic Republic]. / Notes sur les dermatoses en RDP Lao.

We present a descriptive analysis of dermatoses observed in Lao RDP. A total of 421 patients consulted in 3 provinces. A predominance of infectious dermatoses, rarity of acne and absence of skin cancer were notified. These observations are consistent with what has been observed in developing countries in the tropics. But, the causes of consultation are different from other more developed Asian countries.

[Demodecidosis in a patient infected by HIV: successful treatment with ivermectin]. / Démodécie chez un malade infecté par le VIH: guérison par ivermectine.

INTRODUCTION: Demodex is a saprophyte parasite in mammals. In Man, it is associated with differing clinical profiles (rosacea-like dermatitis, folliculitis and blepharitis). We report a case of demodecidosis in an HIV-infected patient that was successfully treated with ivermectin. CASE REPORT: A man from Laos, infected by HIV and treated for glandular tuberculosis, presented with a prurigenous eruption on the face and the pre-sternal and interscapular areas. Direct examination of scraped product and histopathological examinations confirmed the diagnosis of demodecidosis. Clinical cure was obtained after 2 single cures of ivermectin a one month's distance. DISCUSSION: The features of demodecidosis are often similar to those of rosacea. In immunodeficient patients, the semiology remains the same but the eruption is more abundant. During HIV-infection, demodecidosis occurs at the AIDS stage or with a CD4 count lower than 200/mm3. Many anti-dust mite molecules are used to treat the disease but frequently lead to irritation. Administration of a single cure of ivermectin, repeated if necessary, appears to be an interesting alternative to contact anti-dust mite agents.
