Congenital varicella syndrome in a monochorionic diamniotic twin pregnancy.

Congenital varicella syndrome encompasses a broad spectrum of malformations present in children of mothers who developed chickenpox during the first 20 weeks of gestation. We report a case of a monochorionic diamniotic twin pregnancy, with maternal exposure to chickenpox during the thirteenth week of gestation, which produced one symptomatic and one healthy child.

[Prevalence of birth defects according to the level of care in two hospitals, Cali, Colombia, 2012-2013]. / Prevalencia de defectos congénitos diagnosticados en el momento del nacimiento en dos hospitales de diferente nivel de complejidad, Cali, Colombia, 2012-2013.

INTRODUCTION: Birth defects are morphologic alterations diagnosed prenatal or postnatally. Surveillance systems have been used to estimate the prevalence in high complexity care centers; however, the variation of the prevalence among different complexity care centers remains unknown. OBJECTIVE: To compare the prevalence of birth defects among two different complexity care centers in Cali, Colombia. MATERIALS AND METHODS: A descriptive hospital-based study following the methodology of the Latin American Collaborative Study of Congenital Malformations was conducted during 20 months in a medium complexity hospital and a high complexity hospital. RESULTS: During the study period, 7,140 births were attended of which 225 had at least one birth defect. The prevalence of these was of 1.7% (IC95% 1.3-2.0) and 7.4% (IC95% 6.2-8.7) for the medium complexity hospital and the high complexity hospital, respectively. The highest frequencies for the high complexity care center were: ventricular septal defect, 10%; congenital hydronephrosis, 7%; abdominal wall defects, 6%, and hydrocephalus, 5%, while for the medium complexity were: polydactyly, 15%; preauricular skin tags, 8%; congenital talipes equino varus, 7%, and hemangioma, 6%. CONCLUSIONS: The prevalence of birth defects among different complexity care centers varies in quantity, type and severity of the anomaly diagnosed. The surveillance of birth defects is a useful tool for any level of care. It allows estimating more accurately the prevalence of the city, as well being a base for the planning and targeting of resources according to the prevalence of different congenital defects.

Introducción. Los defectos congénitos son alteraciones morfológicas que pueden ser diagnosticadas antes, durante o después del nacimiento. Se han implementado diversos sistemas de vigilancia en hospitales de referencia, principalmente en aquellos de alta complejidad. Objetivo. Comparar la prevalencia de los defectos congénitos en dos hospitales de diferente nivel de complejidad de la ciudad de Cali. Materiales y métodos. Se llevó a cabo un estudio descriptivo basado en la metodología del Estudio Colaborativo Latinoamericano de Malformaciones Congénitas, durante 20 meses en un hospital de mediana complejidad y en otro de alta complejidad. Resultados. Durante el periodo de estudio se atendieron 7.140 nacimientos, en 225 de los cuales se presentó al menos un defecto congénito, con una prevalencia del 1,7 % (IC 95% 1,3-2,0) en el hospital de mediana complejidad y de 7,4 % (IC 95% 6,2-8,7) en el de alta complejidad. En el primero, las frecuencias más altas correspondieron a polidactilia (15 %), apéndice preauricular (8 %) y pie equino varo (7 %), mientras que en el segundo, correspondieron a comunicación interventricular (10 %), hidronefrosis congénita (7 %) y defectos de la pared abdominal (6 %). Conclusiones. La prevalencia de los defectos congénitos varió de un hospital a otro, dependiendo de su nivel de complejidad, y del tipo y la seriedad de los defectos. La vigilancia epidemiológica en los diferentes niveles de atención es una herramienta útil para estimar acertadamente la prevalencia en la ciudad, además de constituir una buena base para la planificación y orientación de los recursos.
