To investigate the prevalence of black yeast-like fungi in skin, hair and nail specimens and to discuss the probability of these species to be involved in disease. Slow-growing black yeast-like fungi in routine specimens were prospectively collected and identified. A questionnaire regarding patient information was sent to physicians regarding black yeast-like fungus positive patients. A total of 20 746 dermatological specimens were examined by culture.

Black yeast-like fungi accounted for 2.2% (n = 108) of the positive cultures. Only 31.0% of the samples, culture positive for black yeast-like fungi were direct https://www.selleckchem.com/products/Vorinostat-saha.html microscopy positive when compared with overall 68.8% of the culture positive specimens. The most prevalent species were Phialophora europaea (n = 29), Coniosporium epidermidis (n = 12), Ochroconis cf. humicola (n = 6) and Cladophialophora boppii (n = 4). These are not common saprobes and thus less likely to be coincidental colonizers. In 10/30 cases, discolouration of nail/skin had been noticed. A limited number of black yeast-like fungi were repeatedly isolated from routine specimens suggesting that they may play a role in superficial selleck infections or as colonizers. “
“Onychomycosis constitutes

up to 50% of all nail disorders. Toenails are generally affected, mostly due to dermatophytes. Terbinafine is the most potent antifungal agent in vitro against dermatophytes. There are few randomised controlled trials using a non-continuous dose of terbinafine. The aim of this open-label pilot study was to reduce the total drug amount, the collateral effects and, specially, the costs; albeit maintaining the same efficacy of the standard regimens. Compare the outcomes

of two different intermittent regimens with the same total amount of the medication (42 tablets in 6 months). Forty-one patients were divided into the following groups: terbinafine 250 mg day−1, for 7 days, monthly or terbinafine 500 mg day−1, once daily, for 7 days, every 2 months, both plus nail abrasion during 6 months. The efficacy was evaluated at months 6, 12 and 18 using the disease free nail criteria. Total cure = group I: eight patients (44.4%) and group II: eight patients (44.4%). Partial Branched chain aminotransferase cure = group I: five patients (27.8%) and group II: four patients (22.2%). Treatment failure = group I: five patients (27.8%) and group II: three patients (16.7%). Recurrence = group I: zero patients (0.0%) and group II: three patients (16.7%). Two intermittent dosing regimens of terbinafine plus nail abrasion proved to be an alternative statistically effective, safe and with reduced drug costs for dermatophytes toenail onychomycosis. “
