A case of peritonitis due to Scedosporium apiospermum in a boy undergoing continuous ambulatory peritoneal dialysis is reported. The finding of suggestive tissual form of the fungus in the effluent hastened the diagnosis of the infection.
Eleven cases of involvement of the genital tract in paracoccidioidomycosis were collected in a retrospective study of the clinical records of 683 patients seen in Porto Alegre, Rio Grande do Sul, Brazil. These cases are herein summarily reported. Eighteen similar cases were gathered in review of the Brazilian literature. Obtained data are discussed.
Of 156 cases of histoplasmosis observed in the State of Rio Grande do Sul (Brazil), during a 21-year period (1978-1999) 137 were included in this study. Sixty-seven per cent of the patients had hematogeneous disseminated histoplasmosis, 24% had a self-limited syndrome (acute pulmonary histoplasmosis, histoplasmoma or primary pulmonary lymph node complex), and 9 per cent had chronic pulmonary histoplasmosis. Clinical, mycological, and epidemiological data were reviewed and commented.
From August to October 1992 a study of prevalence of cutaneous positivity to histoplasmin and paracoccidioidin was carried out in the cities of Cachoeira do Sul (Valley of Jacuí River) and Santo Angelo (western hillside of the PlateAn), Rio Grande do Sul, Brazil. Skin tests were made in 193 soldiers from Cachoeira do Sul and 161 soldiers from Santo Angelo, both groups of 17 to 19 years of age. In Cachoeira do Sul the prevalence of positive tests to histoplasmin was 89% and to paracoccidioidin 82%. In Santo Angelo 48% of the intradermical reactions were positive to histoplasmin and 39% to paracoccidioidin.
The first cases of bone involvement in paracoccidioidomycosis observed in the state of Rio Grande do Sul (Brazil) are reported. Clinical and radiological findings are commented and some peculiarities are pointed out.
The first autochthonous case of acute/subacute disseminated paracoccidioidomycosis observed in a child in Rio Grande do Sul (Brazil) is reported. The disease started with widespread superficial lymphadenopathy six months before the patient was admitted to the hospital. The diagnosis was made through a cervical lymph node biopsy. The spectrum of the clinical forms of the mycosis observed in this State is commented upon.
During the period from January/85 to July/96, 102 cases of paracoccidioidomycosis were observed in a hospital in Belém, PA. Thirteen of these cases were children between 3 and 13 years of age, with a predominance of females (8:5). All patients presented the disseminated subacute form of the mycosis. The high prevalence of the mycosis in children in endemic areas of the Amazon region is discussed.
We report 19 cases of cryptococcosis in children, diagnosed in Belém, PA. In nine patients the variety of the etiologic agent was studied and identified as Cryptococcus neoformans var. gattii. The average age of these patients was 7.8 years (range, 5-13 years) There were 5 girls and 4 boys (ratio, 1.25:1). Amphotericin B treatment (associated with fluconazole 3 or fluocytosine 1) was given but five (56%) of these patients died in the following three months. The existence of highly endemic areas of infection by var. gattii in Pará, Brazil and the severity of the disease due to this fungal variety are commented.

Twenty five cases of disseminated histoplasmosis in patients with AIDS are presented. Mucocutaneous involvement established the diagnosis of disseminated histoplasmosis in 68% of the cases. We point out the importance of histoplasmosis as an opportunistic infection in patients with HIV.
We present a case of cerebral phaeohyphomycosis caused by Cladophialophora bantiana in an apparently immunocompetent patient with a history of intravenous drug use. The diagnosis was achieved in specimens obtained at necropsy by histological and mycological examination, with subsequent identification of the isolate in culture.
