RESUMEN
White piedra of scalp hair is considered a rare entity. We report three cases of this disorder all of whom presented with nodules on the hair. Potassium hydroxide preparations of the hair revealed clustered arthrospores and mature, easily detachable nodules. Cultures grew Trichosporon inkin in 2 patients and Trichosporon mucoides in one patient. Both these fungi are unusual causes of white piedra.

Mucocutaneous and cutaneous candidiasis, though common in children, is often under-reported. The prevalence of Candida dubliniensis in causing these infections in this age group is also largely unknown. A prospective epidemiological cross-sectional study for candidiasis was performed in paediatric patients clinically suspected of candidiasis with oropharyngeal lesions (75 patients), cutaneous lesions (18 patients) and lesions at both sites (2 patients). Candida species were identified by conventional tests. For C. dubliniensis, chlamydospore production, growth on tobacco agar and growth at 45 °C were performed. Nine isolates were confirmed at a reference centre. The rates of candidiasis were 77.3â% (58 out of 75 patients clinically suspected of candidiasis) and 83.3â% (15/18) in oropharyngeal and cutaneous lesions respectively, and 1 of the 2 children with lesions at both sites was diagnosed as having chronic mucocutaneous candidiasis due to C. dubliniensis. The commonest species isolated was Candida albicans, in 41 (70.7â%) patients with oropharyngeal candidiasis and 11 (73.3â%) with cutaneous lesions; C. dubliniensis was isolated from 11 and 3 children respectively. In the paediatric population, C. albicans predominates in mucocutaneous and cutaneous candidiasis, with C. dubliniensis also contributing substantially.

Candida tropicalis is a rare species of Candida causing meningitis. The authors report a young infant who developed Candida tropicalis meningitis following a prolonged stay in a neonatal intensive care unit for respiratory distress and intra-cranial hemorrhage. The child was successfully treated with recommended doses of Amphotericin B and 5-flucytosine for eight weeks.
