1/6. sporotrichosis in Amritsar--a case report.A case of cutaneous, lymphatic sporotrichosis, in a farm labourer, is presented. The diagnosis was established by isolating fungus from the lesion. Dimorphic nature of the fungus was established in vitro by demonstrating the mycelial phase at 25-30 degrees C and yeast phase at 37 degrees C. The patient responded well to oral administration of potassium iodide.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
2/6. empyema associated with pulmonary sporotrichosis.sporothrix schenckii produces an insidious debilitating illness in humans. The lungs are seldom involved and pleural involvement is distinctly unusual, with only four patients described in the literature. We have described a patient with both parenchymal lung disease and pleural effusion. The characteristics of the pleural fluid were unlike those previously reported, and suggest that the coexistence of a parenchymal sporothrix infiltrate may alter the nature of the pleural fluid to mimic an empyema rather than a self-limited hypersensitivity reaction.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
3/6. Musculoskeletal sporotrichosis.sporotrichosis is a chronic, indolent, fungal infection that rarely involves the musculoskeletal system. The etiologic agent, sporothrix schenckii, is ubiquitous in nature and has been isolated from soil, timber, decaying vegetation, and a variety of foliage. The organism gains entrance to the body through trauma to the skin or, in rare instances, by inhalation. The vast majority of infections in humans is characterized by nodular or ulcerated lesions of the cutaneous tissues and adjacent lymphatics. Osteoarticular involvement may occur either by contiguous spread from a cutaneous focus, through direct inoculation of tissue by the organism, or by hematogenous dissemination. The rarity of musculosketetal sporotrichosis often causes a delay in diagnosis which leads to inappropriate therapy and permanent deformity in some patients. Three cases which show a spectrum of bone and joint involvement are presented.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
4/6. Studies on sporotrichosis. Pathogenicity and morphogenesis in the Transvaal strains of sporothrix schenckii.In the Transvaal, two epidemiologic patterns of sporothrix infection occur in man. Evidence gathered from nature, the clinic and the laboratory suggests that these patterns are not the result of either a fixed strain specificity or a random mutation. The differences represent a developmental trend, determined by environmental factors, which gradually transform the wild strains of sporothrix schenckii into variants resembling the earlier descriptions of sporothrix beurmannii. This change, moreover, is regular and predictable.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
5/6. Cutaneous lymphatic sporotrichosis.The first case of cutaneous lymphatic sporotrichosis from Nagaland and a case of cutaneous sporotrichosis from Kerala who had acquired infection from Assam are reported. The diagnosis in both cases were established by isolating sporothrix schenckii from multiple cutaneous lesions. The dimorphic nature of fungus was established in vitro by demonstrating the mycelial phase at 25-30 degrees C and yeast phase at 37 degrees C and pathogenicity to white mice. Both the patients were successfully treated with oral administration of potassium iodide for 3 months.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
6/6. Pulmonary sporotrichosis with hyphae in a human immunodeficiency virus-infected patient. A case report.BACKGROUND: Pulmonary sporotrichosis is a rare event. sporothrix schenckii is a dimorphic fungus and develops at 37 degrees C in yeast form. Usually hyphae are not observed in tissues, although their presence has been occasionally demonstrated in biopsies. CASE: A 37-year-old man, human immunodeficiency virus-1 positive, with a CD4 cell count of 345/mm3, developed a productive cough. A sputum smear revealed the presence of a large amount of long, thin, septated micelia. The hyphae bore oval, sessile conidia. Cultures of sputum yielded numerous colonies of S schenckii. CONCLUSION: This is the first report of hyphae of S schenckii in sputum. This case emphasizes the possibilities of cytology for the diagnosis of mycotic infections. fungi have typical morphologies, and it is possible, on the basis of microscopic evidence, to suspect the nature of the infection early and thus to direct culture procedures.- - - - - - - - - - ranking = 1keywords = nature (Clic here for more details about this article) |
