[Clinico-mycological study of onychomycosis in elderly patients]. / Estudio clínico micológico de onicomicosis en ancianos.

Physical examination of nails was carried out in 210 elderly patients and nail scrapings were obtained from onychomycosis suggested lesions in order to determine their causative agents, incidence and clinical characteristics. Diagnostic was confirmed by the isolation of the agents from 74 patients, mainly from toe-nails (incidence 35.2). Tinea pedis occurred in 25% of the cases and Diabetes mellitus was the most prevalent associated disease and the most frequent clinical characteristics were the thickening, the opacity and the presence of longitudinal strias in the surface of the nails. It was compared the results obtained by microscopic examination and by culture. Trichophyton rubrum was the most common dermatophyte isolated; Candida parapsilosis was dominant among Candida species.

[Isolation of dermatophytes from patients with a presumptive diagnosis of dermatophytosis]. / Aislamiento de dermatofitos en pacientes con diagnóstico presuntivo de dermatofitosis.

Mycological tests were made in 212 patients who had lesions with clinical appearance of dermatophytic infection. The results show that the combined use of direct microscopy and culture helps to detect a larger number of dermatophytic conditions. The findings were the agent most connected with these kinds of mycosis, the most frequent clinical conditions, the lesions in more than one body areas and the most common species. The isolation of Trichophyton soudanense, an endemic species in Africa but considered very rare in Cuba, is reported.

[Chromomycosis with unusual location. Presentation of 2 cases]. / Cromomicosis de localización poco usual. Presentación de 2 casos.
