Doença de Chagas aguda pós-transfusional sem miocardite

Trata-se de paciente do sexo feminino, com 59 anos de idade, procedente de Itaporanga (SP), diabética e nefropata crônica, internada em virtude de surtos de pielonefnte e insuficiência renal aguda. Dentre outras medidas terapêuticas, recebeu transfusão de sangue. Cerca de dois dias após a última transfusão (sangue oriundo de doador, posteriormente identificado como chagásico) encontraram-se formas tripomastigotas de Trypanosoma cruzi em lâmina preparada para execução de hemograma. Iniciou-se tratamento com Benzonidazol. A paciente cursou para, pleuropneumonia e de secreção purulenta cirúrgica isolou-se Klebsiella spp. A septicemia conduziu a paciente ao êxito letal. Nenhuma lesão tecidual foi observada no miocárdio, no sistema nervoso central, adrenal ou nos demais órgãos examinados.

Evaluation of a novel kit (TF-test) for the diagnosis of intestinal parasitic infections

Intestinal parasitic infections are currently a source of concern for Public Health agencies in developing and developed countries. Since three ovum-and-parasite stool examinations have been demonstrated to provide sensitive results, we designed a practical and economical kit (TF-Test) that is now commercially available (Immunoassay Com. Ind. Ltda., S (a) over tildeo Paulo, Brazil). This kit allows the separate collection of three fecal specimens into a preservative solution. The specimens are then pooled, double-filtered, and concentrated by a single rapid centrifugation process. The TF-Test was evaluated in four different laboratories in a study using 1,102 outpatients and individuals living in an endemic area for enteroparasitosis. The overall sensitivity found using the TF-Test (86.2-97.8%) was significantly higher (P<0.01) than the sensitivity of conventional techniques such as the Coprotest (NIL Comercio Exterior Ltda, São Paulo, Brazil) and the combination of Lutz/Hoffman, Faust, and Rugai techniques (De Carli, Diagnostico Laboratorial das Parasitoses Humanas. Metodos e Tecnicas, 1994), which ranged from 48.3% to 75.9%. When the above combined three specimen technique was repeated with three specimens collected on different days, its sensitivity became similar (P > 0.01) to that of the TF-Test. The kappa index values of agreement for the TF-Test were consistent (P < 0.01), being higher and ranking in a better position than conventional techniques. The high sensitivity, cost/benefit ratio, and practical aspects demonstrate that the TF-Test is suitable for individual diagnosis, epidemiological inquiries, or evaluation of chemotherapy in treated communities.

Ectima gangrenoso: Relato de caso

Report of a case of ecthyma gangrenosum with septicemia by Pseudomonas aeruginosa with favorable evolution in a 3-month-old boy. This disease is relatively rare, potentially lethal and the early diagnosis and treatment has an important role in the clinical evolution.

Importância de Yersinia enterocolitica em microbiologia médica

Y. enterocolitica is a human invasive enteropathogen which causes a number of intestinal and extraintestinal clinical symptoms of various degrees of severity, ranging from mild gastroenteritis to mesenteric lymphadenitis, which mimics appendicitis and in rare cases can evolve to septicemia. Infection by Y. enterocolitica can also lead to post-infection immunological sequelae including arthritis, erythema nodosum and glomerulonephritis. Pathogenic Y. enterocolitica strains have traditionally been linked to specific biotypes and serogroups and associated to a variety of phenotypic characteristics related to virulence. Molecular genetics studies have pointed to the importance of the pYV virulence plasmid, which encodes various virulence genes, as well that of specific chromosomal virulence genes, in determining the pathogenesis of this bacterium. Intestinal infections by Y. enterocolitica are mostly self-limiting and usually do not need an antibiotic treatment. The occurrence of this microorganism is not as frequently described in Brazil as it is in other countries, such as Japan, USA and many European countries. This review focuses on the general characteristics, pathogenesis, clinical symptoms, virulence characteristics, treatment and antibiotic susceptibility of Yersinia enterocolitica strains isolated in Brazil and around the world.
