Lesões cutâneas na histoplasmose disseminada progressiva associada com sida Cutaneous lesions in disseminated progressive histoplasmosis associated with AIDS

O polimorfismo das manifestações clínicas na histoplasmose disseminada progressiva associada com SIDA, em especial das lesões cutâneas, pode confundir o clínico e o patologista no diagnóstico da micose. Relatamos um caso dèstaforma clínica da micose, diagnosticada pelo exame direto e histológico e cultivos de aspirado de nódulo subcutâneo e biópsia de pele. Técnicas especiais de coloração e de cultivo das amostras devem ser utilizadas, mesmo em zonas consideradas de baixa endemicidade da histoplasmose, devido à possibilidade da ocorrência de infecções combinadas numa mesma lesão. São comentadas as demais manifestações desta forma clínica da micose.The protean manifestations of progressive disseminated histoplasmosis in AIDS patients (PDW AIDS) specially the cutaneous lesions, may confuse the clinician or the pathologist. A case of PDH/AIDS diagnosed by direct and histologic examination and cultures of subcutaneous nodule aspirate and skin biopsy is reported. The requirement of special histologic and cultures procedures is emphasized. Clinicalmanifestations of the disease are discussed

Molecular characterization of Enterobacteriaceae resistant to carbapenem antimicrobials Caracterização molecular de enterobactérias resistentes aos carbapenêmicos

The present study aimed to genotypically and phenotypically characterize clinical isolates of carbapenem-resistant Enterobacteriaceae collected from inpatients at the University Hospital of Santa Maria, during seven months. Among the clinical isolates subjected to the modified Hodge test (MHT), 62.5% were positive, indicating possible production of carbapenemase. Polymerase chain reaction (PCR) demonstrated that bla KPC was the most frequently found gene (31%), followed by bla IMP (12.5%). Combined use of the methods is needed to identify carbapenem resistance in enterobacteria to prevent their spread and control the infections caused by these organisms
