Non-invasive tests are needed to assess Helicobacter pylori infection, especially to screen a pediatric population. Assure H. pylori Rapid Test (Genelabs Diagnostics, Singapore) is an immunochromatographic assay device intended for the rapid detection of antibodies to H. pylori in human serum, plasma or whole blood. The aim of this study was to evaluate the(More)
Incidence, morbidity and mortality of bacterial meningitis in developing countries are manifold greater than those in the industrialized world. We reviewed retrospectively children with meningitis treated in the paediatric hospital of Luanda in 2004. Among the 555 children, median age 11.0 months, the leading agents were Haemophilus influenzae type b (Hib),(More)
BACKGROUND Helicobacter pylori is mainly acquired in childhood. Although adult studies reported a high prevalence of H. pylori infection in Portugal, the actual rate in children remains unknown. This study aimed to determine the prevalence and the incidence of H. pylori infection in an asymptomatic pediatric population of the Lisbon area and to correlate(More)
OBJECTIVES Both bacterial and host determinants underlying differences in histopathology and clinical outcome in H. pylori pediatric infection, as compared to adults, are still poorly documented. Pediatric studies may provide important insights on H. pylori infection immunopathogenesis, particularly in high gastric cancer risk populations. The present study(More)
Burkholderia pseudomallei is a Gram-negative bacillus and the causative agent of melioidosis, a serious infection associated with high mortality rate in humans. It can be naturally found as an environmental saprophyte in soil or stagnant water, and rice paddies that predominate in regions of endemicity such as Northeast Thailand. B. pseudomallei is a(More)
Brucellosis is a zoonosis that is emerging in some regions of the world. Although brucellosis is a disease of obligatory declaration and is not eradicated in Portugal, no prevalence data is available in this country. In this study, we retrospectively analyzed the data available at the Reference Laboratory at the Portuguese National Institute of Health(More)
