AIMS To determine the incidence of congenital toxoplasmosis in Colombian newborns from 19 hospital or maternal child health services from seven different cities of five natural geographic regions (Caribbean, Central, Andean, Amazonia and Eastern). MATERIALS AND METHODS We collected 15,333 samples from umbilical cord blood between the period of March 2009(More)
BACKGROUND An earthquake in the coffee growing region of Colombia on January 25, 1999 destroyed 70% of the houses in Armenia city. Transitory housing camps still remained until two years after the disaster. Parasitological studies found that, in this population, giardiasis was the most frequent parasitic infection. This study was carried out in order to(More)
OBJECTIVE Describing socio-demographic characteristics in a population of 195 respiratory symptomatic and 18 tuberculosis patients from Calarcá-Quindío, Colombia during 2005. METHODS An active search for individuals having symptomatic tuberculosis was carried out in three urban areas, Calarca's municipal prison and the San Juan de Dios teaching hospital.(More)
A need exists for accurate point-of-care tests for diagnosis of Helicobacter pylori (H. pylori) infection to evaluate a rapid urine-H. pylori antibody test device for detection of H. pylori infection in a point-of-care setting in the United States. A multi-center study in a multi-ethnic population compared the RAPIRUN urine antibody test with the (13)C-urea(More)
Confirmatory tests for congenital toxoplasmosis were evaluated in 23 infected and 31 uninfected newborns. Conventional polymerase chain reaction was better than real-time polymerase chain reaction, but did not identify additional cases. Avidity tests added 2 new cases that were not identified by other criteria. Overall sensitivity was 82.6%. Avidity assay,(More)
UNLABELLED The 13C-urea breath test provides non-invasive testing for Helicobacter pylori infection with the possibility of analysis at the point of care. Point of care tests require accurate and efficient desktop instrumentation. OBJECTIVE To compare results obtained from a new infrared spectrophotometer (10 kg, 2 min sample measurement) to the(More)
The 13C-urea breath test provides accurate, noninvasive diagnosis of active Helicobacter pylori infection and can document posttherapy cure. This study evaluated point-of-care testing with onsite sample analysis with the use of a desktop infrared spectrophotometer. Ambulatory patients (N=320) underwent 13C-urea breath testing, and breath samples were(More)
INTRODUCTION About 500,000 species of fungi have been described to-date, although an estimated between 1 - 1.5 million species may occur. They have a wide distribution in nature, contributing to the decomposition of organic matter and playing a part in the biogeochemical cycles of major nutrients. A small number are considered pathogens of animals and(More)
