BACKGROUND: The heart is the most commonly affected organ by congenital diseases, with and incidence of 0.8 per 100 newborns. Nearly two thirds of all the surgical procedures are now a days performed before the first year of life, improving survival rate and life quality. This study aims to determine the frequency of the surgical interventions performed to treat congenital heart diseases and its complications. METHODS: An observational, descriptive cross sectional study was carried out; with 70 pediatric patients diagnosed and surgically treated for congenital heart diseases. The data was collected from the patient’s medical records using a form. Statistical analysis was performed using SPSS version 15 software. RESULTS: The median age was 1.1 years, 60% of the sample were women. 90% of the heart diseases were non-cyanogenic. The most frequent diagnosis was: persistence of the arterial duct (58.57%), followed by interventricular communication (12.86%). The type of procedures corresponds to the heart disease, thus 58.57% were performed for closure of arterial duct persistence and 12.86% were surgical repairs for closure of interventricular communication. The median stay in the intensive care unit was 4 days and the median stay in general hospitalization room was 5 days. The main complications in this pediatric population undergoing a surgical procedure were: pneumonia (11.4%) and sepsis of unspecified origin (8.6%). CONCLUSION: Treatment for heart diseases were performed at early ages (average age= 2.5±3.2). More than half of the surgical procedures for congenital heart disease were performed to correct the persistence of the ductus arteriosus, the main complication was pneumonia.

INTRODUCCION: La obesidad constituye en la actualidad un problema de salud publica de causa multifactorial relacionado con comorbilidades como la diabetes mellitus tipo II, resisten­cia a la insulina y el sindrome metabolico. El objetivo del presente estudio fue determinar los factores asociados a la obesidad abdominal en los estudiantes de la Facultad de Medicina de la Universidad Catolica de Cuenca. METODO: Se realizo un estudio analitico, observacional y transversal de factores asociados. La muestra para la poblacion finita se calculo basandose en un universo de 1376 estudiantes ob­teniendose una muestra minima de 300 estudiantes. Los datos de filiacion, ano de estudio, el estado nutricional, los antecedentes familiares, la presencia de hipertension y la actividad fisica fueron evaluados; para determinar la asociacion se utilizo el estadistico Odds Ratio, con un in­tervalo de confianza al 95% y un valor de P
