ABSTRACT

Abstract: Sensitive skin is a condition characterized by stinging, burning and itching sensations. The diagnosis, pathophysiology and treatment of sensitive skin are still under discussion. In the last years, studies on its epidemiology have been performed, showing a high prevalence and impact on quality of life. Brazilian population was also considered in these studies. Cosmetics, climate changes and skin barrier impairment are the main factors that contribute for skin hyperreactivity. New studies are trying to bring new knowledge about the theme. This review will describe data on epidemiology, triggering factors, pathophysiology, diagnosis and treatment.

ABSTRACT

A toxoplasmose é uma das infecções parasitárias mais comuns em humanos e possui ampla distribuição geográfica. Segundo estudos realizados no Brasil, a soroprevalência de toxoplasmose na população adulta em geral varia aproximadamente entre 40% e 80%, sendo que, no Rio Grande do Sul, cerca de 82% da população adulta apresenta sorologia positiva para o Toxoplasma gondii. A soroprevalência varia conforme as regiões de estudo, sobretudo quando relacionadas a condições sanitárias e índices socioeconômicos. O objetivo deste estudo foi realizar uma revisão bibliográfica sobre a toxoplasmose adquirida durante a gestação. A transmissão vertical apresenta relevância pelos danos causados ao neonato, como doença severa ou discreta. Entretanto, a toxoplasmose congênita ou suas sequelas podem ser evitadas. Definir os fatores de risco em cada população é de fundamental importância para determinar as estratégias de promoção à saúde. Estratégias essas que devem ser baseadas no conhecimento dos fatores que afetam o comportamento das gestantes. Oportunizar palestras de prevenção por meio de medidas profiláticas e acompanhamento pré-natal, seguidas de monitoramento trimestral, certamente ajudarão a reduzir os danos causados pela infecção congênita, evitando sequelas ao neonato

ABSTRACT

O presente trabalho objetivou investigar os resultados da triagem sorológica para doença de Chagas (DCH) dos doadores do Banco de Sangue do município de Santiago, Rio Grande do Sul, no período de junho de 2001 a maio de 2011. Os dados foram obtidos por meio do Sistema HEMOVIDA®, tendo por base 10.164 bolsas de sangue. Observou-se que 2,7% (272) das doações apresentaram sororreatividade para Trypanosoma cruzi, sendo esta a primeira causa de descarte das bolsas dentre as doenças infecciosas sorologicamente testadas. Entre as bolsas reagentes, 6,3% (17) também apresentaram resultados positivos para outros marcadores sorológicos: hepatite B (9 casos), hepatite C (4 casos), HTLV I/II (3 casos) e sífilis (1 caso). Embora os testes sorológicos confirmatórios e a caracterização da forma clínica sejam etapas relevantes realizadas em centros de referência, os resultados apontam elevado índice de sororreatividade na triagem para T. cruzi nesta área do estudo. Evidenciou-se que a via de transmissão transfusional de T. cruzi pode ocorrer na região noroeste do RS, não sendo permitida, portanto, nenhuma negligência quanto à obrigatoriedade do exame sorológico para DCH nos bancos de sangue

ABSTRACT

Hazards and critical control points (CCP) associated with meat balls and kibbe preparations in a hospital kitchen were determined using flow diagrams and microbiological testing of samples collected along the production line. Microbiological testing included counts of mesophilic and psicrothrophic microorganisms, yeasts and molds, total and fecal coliforms, "C. perfingens", coagulase positive staphylococci, bacteria of the "B cereus" group and detection of "Salmonella". Time/temperature binomial was measured in all steps of preparation. A decision tree was used to help in the determination of CCPs. The detected hazards were: contamination of raw meat and vegetables, multiplication of the microorganisms during meat manipulation, poor hygiene of utensils and equipment, and survival of microorganisms to the cooking process. Cooking and hot-holding were considered CCPs. The results stress the importance of the implementation of a training program for nutritionists and foodhandlers and the monitoring of CCPs and other measures to prevent foodborne diseases

ABSTRACT

Aeromas has been described as an emergent foodborne pathogen of increasing importance. In this study, we report that 48(per cent) of 50 Pintado fish samples collected at the retail market of São Paulo city were positive for Aeromas sp, as detected by the direct plating method. When the presence/absence method was used, the positivity was 42(per cent). A caviae was the most frequent species, followed by A. hydrophila and A. sobria. Production of cytotoxic enterotoxin, observed in suckling mouse assay, was detected in 67(per cent) of A sobria strains, in 60(per cent) of A. hydrophila strains and in 40(per cent) of A. caviae strains. In vitro tests, performed with HEp-2 cells, showed that 88(per cent) of A. hydrophila, 27(per cent) of A. sobria and 13(per cent) of A. caviae strains were positive for this toxin. The in vivo production of cytotonic enterotoxin, tested after heating the filtrates at 56degreeC for 20 minutes, was detected in 17(per cent) of A. sobria, in 10(per cent) of A. caviae and in none of A. hydrophila strains in vivo. All analyzed strains did not alter HEp-2 cells. 20(per cent) and 16(per cent) of A. sobria and A. caviae isolates, respectively, presented capacity to adhere to HEp-2 cells. In counterpart, invasion of HEp-2 cells was not observed in any isolate. The Aeromonas isolates were sensitive to the majority of the antimicrobiol agents tested.
