OBJECTIVE To describe the genotypic variability of group A rotavirus (RVA) found in immunosuppressed and non-immunosuppressed pediatric patients treated at the Hospital de Clínicas da Universidade Federal do Paraná (HC-UFPR), Curitiba, Paraná. METHODS A cross-sectional study was conducted with 1,140 stool samples collected from April, 2001 to December, 2008 in outpatients and hospitalized pat...

Strongyloides is endemic in parts of the United States. Most often it is asymptomatic but it has a wide range of clinical presentations. Because of the unusual capacity of strongyloides for autoinfection, it can cause hyperinfection, when it effects the pulmonary and gastrointestinal systems, or disseminated infection, when other organs are involved. Both hyperinfection and disseminated strongy...

Cytomegalovirus (CMV) is an important cause of morbidity and mortality in immunosuppressed patients. Though acute lymphoblastic leukemia (ALL) is an immunosuppressed state, CMV disease has been reported infrequently. We present a patient of adult B lineage ALL who was on maintenance chemotherapy and developed CMV pneumonia. Patient was managed with intravenous ganciclovir and had successful out...

Objective: The goal of this study was to better define the frequency of unexpected diagnoses made by open lung biopsy, the frequency with which biopsy results lead to a change in clinical management, and the frequency of procedural complications in patients with diffuse pulmonary infiltrates requiring mechanical ventilation. Methods: This is an observational, non-controlled study, with prospect...

Saprophytic fungi are being increasingly recognized as etiologic agents of mycoses in immunosuppressed patients. We report a case of subcutaneous infiltration by Aureobasidium pullulans, likely due to traumatic inoculation, in a neutropenic patient during chemotherapy for chronic lymphocytic leukemia. The patient was treated with amphotericin B deoxycholate but was subsequently switched to itra...

Abstract We herein present the case of a patient with anal condylomatosis concomitant histoplasmosis, whose diagnosis was only possible through collection material and subsequent evidence primary pulmonary focus. Histoplasmosis is fungal disease contamination occurs respiratory route, it can spread to digestive tract, but anus rarely affected. It important have high degree suspicion make diagno...

To evaluate the value of single and nested PCRs for diagnosis of Pneumocystis carinii pneumonia (PCP) in a variety of respiratorily distressed patient groups, 574 respiratory samples from 334 patients (89 human immunodeficiency virus [HIV]-positive patients, 61 transplant recipients, 66 malignancy patients, 34 otherwise immunosuppressed patients, and 84 immunocompetent patients) were prospectiv...

Strongyloidiasis is a potentially serious infection in immunocompromised patients. Thus, the availability of sensitive and specific diagnostic methods is desirable, especially in the context of immunosuppressed patients in whom the diagnosis and treatment of strongyloidiasis is of utmost importance. In this study, serological and molecular tools were used to diagnose Strongyloides stercoralis i...

Three rapid assay techniques (latex agglutination, laser nephelometry, and EMIT enzyme immunoassay) have been evaluated for serial monitoring of the serum C reactive protein (CRP) concentration in immunosuppressed patients with fever. Radial immunodiffusion assay was used as a reference method. Latex agglutination reliably distinguished between normal and raised serum CRP concentrations. Enzyme...
