BACKGROUND Fractal geometry is employ to characterize the irregular objects and had been used in experimental and clinic applications. Starting from a previous work, here we made a theoretical research based on a geometric generalization of the experimental results, to develop a theoretical generalization of the stenotic and restenotic process, based on(More)
BACKGROUND HIV diagnosis, prognostic and treatment requires T CD4 lymphocytes' number from flow cytometry, an expensive technique often not available to people in developing countries. The aim of this work is to apply a previous developed methodology that predicts T CD4 lymphocytes' value based on total white blood cell (WBC) count and lymphocytes count(More)
Receiving the diagnosis of Down syndrome: what do the parents think? Background: Having a child with Down syndrome (DS) is usually unexpected and stressful. Aim: To describe the experiences of parents of children with DS at the time of diagnosis. Material and Methods: A self-administered survey was answered by 345 parents (62% women) with an offspring with(More)
OBJECTIVE Studying geometric dynamics for annual cases of dengue recorded in Colombia from 19902006 by making an analogy with a probabilistic random walk. METHODS The geometric dynamics for the number of annual cases of dengue registered in Colombia for 1990-2006 was mathematically analyzed as a probabilistic random walk, building the total probability(More)
