Prevalencia de síntomas cutáneos asociados a dermatitis de contacto y su relación con factores sociodemográficos y ocupacionales en el personal asistencial de un laboratorio clínico de la ciudad de Bogotá en el año 2012

El objetivo fue determinar la prevalencia de síntomas cutáneos asociados a Dermatitis de Contacto y su relación con factores socios demográficos y ocupacionales, en el personal asistencial de un laboratorio clínico de la ciudad de Bogotá en el año 2012. Es un estudio descriptivo observacional de corte transversal (n= 100) se estimo la prevalencia de síntomas cutáneos de Dermatitis de Contacto y sus factores asociados socio demográficos y ocupacionales en el personal asistencial de un laboratorio clínico de la ciudad de Bogotá en Se usó como instrumento el cuestionario Nórdico para Enfermedades profesionales de la piel (NOQS) en su versión larga validada al español. La sensibilidad y especificidad del cuestionario aplicado en lo referente a las preguntas sobre eczema fue del 96 y 75% respectivamente. Los resultados encontrados fueron que la prevalencia de la sintomatología cutánea de Dermatitis de contacto en la población estudiada fue de 30% para manos y de 16 % para muñecas o antebrazos.

Big Data or Right Data?

Abstract Big data nowadays is a fashionable topic, independently of what people mean when they use this term. But being big is just a matter of volume, although there is no clear agreement in the size threshold. On the other hand, it is easy to capture large amounts of data using a brute force approach. So the real goal should not be big data but to ask ourselves, for a given problem, what is the right data and how much of it is needed. For some problems this would imply big data, but for the majority of the problems much less data will and is needed. In this talk we explore the trade-offs involved and the main problems that come with big data using the Web as case study: scalability, redundancy, bias, noise, spam, and privacy.
