1/159. Two cases of tinea pedis caused by Scytalidium hyalinum.Two cases of tinea pedis due to Scytalidium hyalinum, the first to be described in italy, are reported. The patients were a 41-year-old woman and a 35-year-old man who had spent periods in the Caribbean. The clinical manifestations were indistinguishable from those caused by dermatophytes. In the women they were striking with 'moccasin foot' type lesions, whereas in the man they were less evident, with minor plantar desquamation and interdigital maceration. diagnosis was based on direct mycological microscopic examination and culture. Clinical and mycological remission were obtained with systemic itraconazole therapy. These cases are reported because infections caused by Scytalidium hyalinum are rare in europe and their clinical and mycological diagnosis, as well as therapy, may be problematic.- - - - - - - - - - ranking = 1keywords = tinea (Clic here for more details about this article) |
2/159. Microsphaeropsis olivacea as an etiological agent of human skin infection.Microsphaeropsis olivacea is reported as the agent of a case of human skin infection in an otherwise healthy woman. This fungus has not been reported previously as causing disease in humans. It was identified on the basis of its production of pycnidia and conidial structures typical of the Coelomycetes, and by its light brown, ellipsoid to cylindrical and thick walled conidia. The in vitro inhibitory activity of amphotericin b, fluconazole, flucytosine, itraconazole, ketoconazole and miconazole was determined.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
3/159. An epidemic outbreak of malassezia folliculitis in three adult patients in an intensive care unit: a previously unrecognized nosocomial infection.BACKGROUND: malassezia is a lipophilic fungus commonly found in normal human skin. infection of the hair follicle by malassezia furfur occurs in patients with predisposing factors such as diabetes or immunosuppression, or who are undergoing antibiotic treatment. malassezia furfur folliculitis is an infrequent nosocomial infection which may be associated with fomite transmission. methods: We reviewed the clinical files of three adult patients from an intensive care unit (ICU) who simultaneously developed folliculitis through malassezia infection. We specifically analysed predisposing factors, possible transmission modes, characteristics of skin lesions, results of biopsies and cultures, treatment, and patient outcome. RESULTS: The three male patients were in neighboring beds and they all had factors that predisposed them to underlying immunosupression. Simultaneously, and within hours of each other, they developed erythematous follicular papules and pustules on the face and chest. The skin biopsies revealed an acute folliculitis with abundant round to oval yeasts of up to 5 microm in diameter. Stains for fungi (Schiff's peryodic acid, Grocott and silver methenamine) revealed numerous unipolar budding yeasts without hyphae, consistent with M. furfur. Conventional cultures were negative. The diagnosis of folliculitis by M. furfur was established and antifinigal treatment initiated, with adequate outcome of the dermatosis. After this outbreak, the aseptic and hygienic measures of the health care personnel of the ICU were reviewed and corrected. CONCLUSIONS: The simultaneous emergence of this superficial infection by M. furfur suggests fomite participation. This dermatomycosis is an infrequent nosocomial infection in adults, which to our knowledge has not been previously reported.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
4/159. Disseminated trichosporonosis with Trichosporon asahii.Trichosporon asahii fungemia was associated with multiple, purpuric, papular lesions on the abdomen and extremities in a 53-year-old man with acute myeloblastic leukemia. Histologically, budding yeasts were demonstrated in the dermis. The yeast-form fungus was identified as T. asahii.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
5/159. cryptococcosis during systemic glucocorticosteroid treatment.cryptococcosis is an opportunistic infection caused by a fungus, cryptococcus neoformans. It is usually seen in immunocompromised patients with AIDS, leukaemia, lymphoma, sarcoidosis or immunosuppressive treatments. We describe a patient who was treated with systemic glucocorticosteroids for 4 years because of lung sarcoidosis. During the last year of treatment, a papular eruption developed which later became ulcerative. In a histopathological examination of a skin biopsy, there was granulomatous inflammation, and the disease was treated as sarcoidosis without success. After 1 year's unsuccessful treatment, another skin biopsy and skin fungal culture revealed C. neoformans. Cryptococcal antigen was found in blood and cerebrospinal fluid, too. The patient was successfully treated first with an amphotericin-B-flucytosine combination and later with fluconazole.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
6/159. Malignant otitis externa caused by malassezia sympodialis.BACKGROUND: Malignant otitis externa caused by fungal infections is rare. A review of the literature showed only 9 cases, and the causative fungus in all cases was aspergillus. This article reports an unusual case caused by malassezia sympodialis. methods: A 53-year-old man with non-insulin dependent diabetes presented with malignant otitis externa. He deteriorated despite treatment with intravenous antipseudomonal therapy and surgical debridement. Microbiologic tests revealed M. sympodialis. He responded rapidly to intravenous amphotericin. RESULTS: Systemic human infections caused by M. sympodialis have not been reported. M. furfur systemic infection is rare and has been associated lipid hyperalimentation by means of a central catheter. Only 1 other case of M. fungemia without these associated risk factors has been reported. CONCLUSIONS: The first case of malignant otitis externa caused by M. sympodialis is presented. It highlights the difficulty of initial biologic diagnosis and the need for lipid-enriched media to grow this fastidious organism.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
7/159. Pityrosporum folliculitis: renal transplantation case report.Pityrosporum folliculitis is caused by the fungus Pityrosporum ovale. It is characterized by the presence of pruriginous follicular papulae and papulae-pustules in face, upper part of the trunk, and upper limb root. It is more prevailing in places with hot and humid climates. Its incidence can be associated with either immunosuppressive or chemotherapy states secondary to pathologies. We report herewith a case of pityrosporum folliculitis in a patient who had previously underwent kidney transplantation and these result of the itraconazol therapeutics given.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
8/159. mycetoma and phaeohyphomycosis caused by phialophora parasitica in thailand.phaeohyphomycosis caused by phialophora parasitica is rare and it has never been documented in thailand. The first two Thai cases of phaeohyphomycosis caused by P. parasitica were recognized in early 1990 at Ramathibodi Hospital, Bangkok, thailand. Both patients had underlying diseases. The fungus developed in abscesses with pigmented mycelium at the lower extremity. Cultures from pus and tissue biopsies were positive for dematiaceous fungi. light microscopic features suggested P. parasitica and which was illustrated by both scanning and transmission electron microscope. The first case was treated with itraconazole with a satisfactory initial response. The second case was successfully treated by surgical removal of the entire lesion.- - - - - - - - - - ranking = 0.16153517672877keywords = fungus (Clic here for more details about this article) |
9/159. Cutaneous infection caused by Cylindrocarpon lichenicola in a patient with acute myelogenous leukemia.Cylindrocarpon lichenicola is a saprophytic soil fungus which has rarely been associated with human disease. We report the first case of localized invasive cutaneous infection caused by this fungus in a 53-year-old male from the rural midwestern united states with relapsed acute myelogenous leukemia. On admission for induction chemotherapy, the patient was noted to have an abrasive laceration between the fourth and fifth metacarpophalangeal joints and on the dorsum of the right hand, which progressed to frank ulceration following chemotherapy. A biopsy provided an initial diagnosis of an invasive fungal infection consistent with aspergillosis based on the histopathological appearance of the mold in tissue. Multiple positive fungal cultures which were obtained from the biopsied tissue were subsequently identified by microscopic and macroscopic characteristics to be C. lichenicola. The infection resolved following marrow regeneration, aggressive debridement of the affected tissue, and treatment with amphotericin b. This case extends the conditions associated with invasive disease caused by C. lichenicola.- - - - - - - - - - ranking = 0.32307035345754keywords = fungus (Clic here for more details about this article) |
