Análisis descriptivo del costo de la atención y prevención del intento suicida en adolescentes 2010

Introducción: El suicidio es un problema de salud pública mundial. En Colombia los jóvenes son la población más vulnerable. Son evidentes las importantes pérdidas desde el punto de vista moral, pero también son considerables los gastos de dinero que éste genera. No hay evidencia disponible del costo de la atención, ni de la prevención del intento de suicidio en el país. Es pertinente hacer cuantificaciones del costo de la atención y prevención del intento de suicidio, para lograr una mejor administración de recursos. El objetivo de este estudio es cuantificar los costos directos promedio derivados de la atención médica del intento de suicidio en una clínica infantil y compararlos con los costos de una estrategia de prevención primaria (programa TeenScreen) implementada en un colegio durante el 2010 en Bogotá, en menores de 18 años. Métodos: Estudio descriptivo, transversal, que cuantifica y promedia costos médicos directos de la atención y del programa de prevención; con base en costos tarifarios. Resultados: El costo promedio para la atención de pacientes con diagnóstico de intento de suicidio y para el programa de prevención fue de $1,745,612 pesos Colombianos (n=41) y de $68,536 (n= 171) respectivamente. Casi la mitad del costo para internación fue invertido en pacientes que requirieron hospitalización en Unidad de Cuidado Intensivo Pediátrico (UCIP) el costo promedio para atención de estos pacientes fue de $12,518,888. Discusión: La prevención del intento de suicidio resulta menos costosa que su atención hospitalaria, especialmente si se requiere UCIP.

Geometric characterization of red blood cells. Differentiation of normal and pathologic samples

Introduction. Fractal geometry measures the irregularity of abstract and natural objects with the fractal dimension. Fractal calculations have been applied to the structures of the human body and to quantifications in physiology from the theory of dynamic systems.Material and Methods. The fractal dimensions were calculated, the number of occupation spaces in the space border of box counting and the area of two red blood cells groups, 7 normal ones, group A, and 7 abnormal, group B, coming from patient and of bags for transfusion, were calculated using the method of box counting and a software developed for such effect. The obtained measures were compared, looking for differences between normal and abnormal red blood cells, with the purpose of differentiating samples.Results. The abnormality characterizes by a number of squares of occupation of the fractal space greater or equal to 180; values of areas between 25.117 and 33.548 correspond to normality. In case that the evaluation according to the number of pictures is of normality, must be confirmed with the value of the area applied to adjacent red blood cells within the sample, that in case of having values by outside established and/or the greater or equal spaces to 180, they suggest abnormality of the sample.Conclusions. The developed methodology is effective to differentiate the red globules alterations and probably useful in the analysis of bags of transfusion for clinical use 

The pattern of fall of serum bilirubin after operative relief of obstructive jaundice. A preliminary report

This is the beginning of a prospective study on patients who have obstructive jaundice to see how the serum bilirubin falls after operative relief of the obstruction. Seven of such patients have been studied; four had carcinoma of the head of the pancreas while the other three had choledocholithiasis. The patients with carcinoma had relief of the jaundice through a biliary-enteric anastomosis and those with common bile duct stones had choledochotomy with stone extraction which was completed with insertion of a T-tube. Serial bilirubin estimations were then performed post-operatively to chart the pattern and rate of descent of this in each patient. Our observations suggest that the pattern of fall of serum bilirubin after successful decompression of the extra-hepatic biliary tree exhibit a distinct pattern regardless of the surgical procedure performed for the relief of the obstruction.
