Due to increased interest in economic evaluation and the rapid international spread of new healthcare technologies across borders, there is a need to interpret economic evaluations on a worldwide basis. We conducted a multinational cost-effectiveness analysis, from a government payer perspective, comparing four primary oral treatment regimens for onychomycosis of the fingernails and toenails: griseofulvin, itraconazole, ketoconazole and terbinafine. We used a four-step pharmacoeconomic research model which includes all relevant factors affecting costs in 13 countries: Austria, Belgium, Canada, Finland, France, Germany, Greece, Italy, The Netherlands, Portugal, Spain, Switzerland and the U.K. A worldwide meta-analysis of published clinical data served as the statistical input for the pharmacoeconomic model, and demonstrated that terbinafine had the highest success rates (95.0% and 78.3%) of the clinical comparators for fingernails and toenails, respectively. We found that terbinafine was the most effective therapy in relation to cost (therefore giving it the lowest cost-effectiveness ratio) for both infections in all health-care systems analysed.

Although Malassezia yeasts are a part of the normal microflora, under certain conditions they can cause superficial skin infection, such as pityriasis versicolor (PV) and Malassezia folliculitis. Moreover the yeasts of the genus Malassezia have been associated with seborrheic dermatitis and dandruff, atopic dermatitis, psoriasis, and, less commonly, with confluent and reticulated papillomatosis, onychomycosis, and transient acantholytic dermatosis. The study of the clinical role of Malassezia species has been surrounded by controversy due to the relative difficulty in isolation, cultivation, and identification. This review focuses on the clinical, mycologic, and immunologic aspects of the various skin diseases associated with Malassezia. Moreover, since there exists little information about the epidemiology and ecology of Malassezia species in the Italian population and the clinical significance of these species is not fully distinguished, we will report data about a study we carried out. The aim of our study was the isolation and the identification of Malassezia species in PV-affected skin and non-affected skin in patients with PV and in clinically healthy individuals without any Malassezia associated skin disease.

Two cases of cutaneous phaeohyphomycosis, one with a nodular appearance and the other with an erythematous infiltrating patch, are reported in immunocompromised patients. Diagnosis was based on histological examination, which revealed hyphae and round-shaped fungal cells in a granulomatous dermal infiltrate, and on identification of the moulds when biopsy fragments were cultured on Sabouraud-dextrose agar without cycloheximide. The pathogens were Alternaria tenuissima in the first case and A. alternata in the second. The fungi were examined by scanning electron microscopy. The patients were checked for bone and lung involvement and were then treated with surgical excision and itraconazole, and itraconazole only, respectively, with clinical and mycological resolution.
