Quantitative cultures were obtained using contact plates to determine whether the quantity and composition of Malassezia species at a given anatomic site in normal individuals differs from that of patients with various cutaneous dermatoses. The sample included 20 clinically healthy individuals (without any dermatosis) and 110 patients with dermatoses(More)
Fifty-five strains, either authentic or ex-type, of seven Malassezia species were investigated for in vitro susceptibility to various concentrations (0.03-64.0 microg/mL) of three azole drugs, ketoconazole, voriconazole and itraconazole, as well as the allylamine terbinafine, using the agar dilution method. All strains of the seven Malassezia species were(More)
The new taxonomic structure of the lipophilic genus Malassezia was presented with key characteristics for the seven described species. Among techniques used for epidemiological surveys, the pulsed field gel electrophoresis (PFGE) was found to be of little value in contrast to randomly amplified polymorphic DNA (RAPD). Immunological studies still yielded(More)
We have investigated the incidence of the lipophilic fungi Pityrosporum orbiculare and P. ovale on clinically normal skin in newborn children and in children at the age of 6 months, 1 year, 5 years, 10 years, and 15 years. P. orbiculare was absent in children of less than 5 years of age. It was present in the highest incidence (93%) in the 15-year-old(More)
The genus Malassezia was recently revised to include seven species, but the clinical significance of each of these species is not clearly understood. To obtain a better understanding of the contribution of individual Malassezia species to the epidemiology of pityriasis (tinea) versicolor, we used Leeming-Notman medium to culture patient skin specimens(More)
Atopic dermatitis (AD) is a chronic, itching, inflammatory skin disease which is associated with asthma and/or hay fever and a familial occurrence of these conditions. Genetic factors are important in the development of AD, but the exact hereditary pathway is still unknown. Dry skin and the weakened barrier function in patients with AD is very important for(More)
The lipophilic yeast Pityrosporum ovale is a member of the normal human cutaneous flora in adults but also associated with several skin diseases. In pityriasis versicolor, under the influence of predisposing factors, P. ovale changes from the round blastospore form to the mycelial form. A great problem in pityriasis versicolor is the high rate of recurrence(More)
BACKGROUND Development of the skin barrier continues up to 12 months after birth; therefore, care must be taken when cleansing and bathing infants' skin. Available guidelines for skin care in newborns are, however, limited. In 2007, the 1st European Round Table meeting on 'Best Practice for Infant Cleansing' was held, at which a panel of expert(More)
BACKGROUND Dermatophyte infections have been considered rare in psoriasis. However, there are data indicating that tinea unguium is as common or even more common in psoriasis compared with healthy controls. Tinea unguium is generally a secondary event to tinea pedis infection. OBJECTIVES To study the prevalence of tinea pedis and tinea unguium in(More)
The distribution of terbinafine in stratum corneum dermis-epidermis (without stratum corneum), sebum, hair, nails and plasma was studied in human male volunteers during and after 250 mg orally once daily for 28 days. The highest concentration was seen in sebum, 56.07 micrograms/g, after 14 days of therapy. The concentration was still 1.0 microgram/g 44 days(More)
