Retrospective study of onychomycosis in Italy:1985-2000
No full textCases of onychomycosis diagnosed by mycological examination in three mycology units (Florence, Siena and Milan) of central and northern Italy over the 15-year period, 1985-2000, were studied retrospectively. The number of cases was 4046 (1952 women, 2094 men). Dermatophytes were isolated in 2859, yeasts in 655 and moulds in 532 cases. The most frequent dermatophyte was Trichophyton rubrum (87%), followed by T. mentagrophytes var. interdigitale (10%). Candida albicans (93.2%) was the prevalent yeast. Moulds were mainly Scopulariopsis brevicaulis (48.6%) and Aspergillus spp. (25.2%). Dermatophytes and moulds most commonly infected the toenails, yeasts the fingernail
Skin and nail infections due to Fusarium oxysporum in Tuscany, Italy
No full textNine cases of skin and nail infection due to Fusarium oxysporum, diagnosed in Tuscany in the period 1985-97, are described. Two manifested as interdigital intertrigo of the feet and seven as onychomycosis. All were diagnosed on the basis of repeated mycological examination, direct microscope observation and culture, as well as histological examination of biopsy specimens in two cases of intertrigo. Fragments of the fungal colonies were examined by scanning electron microscopy (SEM) for more detailed observation of fungal morphology. All patients had normal immune status and a history of the infection extending several years. Four of the patients with onychomycosis were treated with oral itraconazole, and clinical and mycological recovery was achieved in three cases. Two others were treated with cyclopyrox nail lacquer, successfully in one case. One patient with intertrigo was treated with oral itraconazole and one with oral terbinafine; both were also treated and with topical drugs, however clinical recovery was not confirmed by the mycological results
Subcutaneous alternariosis
No full textA case of subcutaneous alternariosis caused by Alternaria alternata is reported in a 52-year-old male who underwent kidney transplantation 1 year earlier. The infection manifested as a vegetating mass about 7 cm in diameter on the right forearm. Histological examination with Grocott staining and periodic acid-Schiff diastase revealed fungal spores and hyphae with chronic granulomatous inflammation. Biopsy fragments inoculated on Sabouraud-glucose agar with chloramphenicol produced colonies which were identified as Alternaria alternata on the basis of macroscopic and microscopic character
