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)
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)
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)
BACKGROUND Congenital anomalies (CAs) cause nearly one third of infant deaths worldwide. Various surveillance systems have been established, such as the Bogota Congenital Malformations Surveillance Program (BCMSP). Some CAs are of special interest to pediatric surgeons: omphalocele, gastroschisis, intestinal and esophageal atresia, anorectal malformations,(More)
