Importance of abdominal circumference and body mass index values in predicting male hypogonadism - A practical approach.

OBJECTIVE: The objective of this study was to correlate the values of abdominal circumference (AC) and body mass index (BMI) with the levels of total testosterone (TT), free testosterone (FT) and sexual hormone binding globulin (SHBG). We aimed to analyze the association between the anthropometric values and variations in the hormonal levels. SUBJECTS AND METHODS: A transversal prospective study was conducted. A total of 159 patients were included in the study. RESULTS: BMI was inversely correlated with TT and SHBG (p = 0.02 and p = 0.006, respectively). AC was also inversely correlated withTT and SHBG (p = 0.006 and p < 0.0001, respectively). However, BMI did not correlate signicantly with these hormonal levels after adjusting for age. CONCLUSION: This finding led to the conclusion that AC had a stronger inverse correlation than BMI with TT and SHBG. Our data suggested that AC alone can be used as an anthropometric parameter to help simplify the identification of men with low serum TT levels.

[Management of the abdominal wall in sepsis. Comparison of two techniques]. / Manejo de la pared abdominal en sepsis. Comparación entre dos técnicas.

OBJECTIVE: To compare two techniques of open abdomen management in patients with abdominal sepsis. INTRODUCTION: Some patients with abdominal sepsis will require open abdomen management to avoid abdomen compartment syndrome. We compare use of the Bogota bag with a technique developed at our Institution with a subcutaneous polyethylene bag. METHODS: Thirty nine consecutive patients with abdominal sepsis who were managed with open abdomen. RESULTS: Twenty one patients with Bogota bag and 18 patients with subcutaneous polyethylene bag. Patients with Bogota bag had more report surgery intrabdominal complications compared with patients with subcutaneous polyethylene bag (p = 0.04, p = 0.037, respectively). Mortality was the same. CONCLUSIONS: Use of subcutaneous polyethylene bag in patient with abdominal sepsis and open abdomen appears safer when compared with Bogota bag.

Infección tuberculosa en contactos de pacientes positivos y negativos al VIH con tuberculosis : resultados preliminares / Tuberculosis infection (TB) in household contacts of patients HIV-positive and HIV-negative with TB

Los datos disponibles sobre el grado de infectividad de las personas positivas al virus de inmunodeficiencia humana (VIH) con tuberculosis (TB) son controversiales. El presente estudio determina el grado de infectividad tuberculosa de los individuos positivos al VIH con TB activa entre sus convivientes. Los contactos convivientes de sujetos VIH positivos con TB y de sujetos VIH negativos con TB son tamizados para la infección tuberculosa y la enfermedad activa en sus residencias en una visita inicial y varias de seguimiento, mediante la prueba de tuberculina, exámen físico, historia clínica y procedimientos radiográficos. En la visita inicial, punto de corte del presente análisis, la reactividad al derivado protéico purificado (PPD) (Induración, mayor o igual que, 10mm) ha mostrado ser menor en los contactos de individuos positivos al VIH (41/84 [46.6//] que en aquellos de individuos negativos al VIH (118/195 [61.8//] (RR=0.72, IC 95//:0.57, 0.92). Entre los convivientes, menor o igual a, 15 años, la reactividad al PPD ha mostrado ser también menor en aquellos de sujetos VIH-positivos (21/46 [45.7//]) que en los de sujetos VIH negativos (40/70 [57.1//]) (RR=0.80, IC 95//:0.55, 1.16). Esta diferencia persiste luego de evaluar aquellos contactos, mayores o igual a 15 años que no mostraron anergia. Estos resultados tienden a sugerir un menor grado de transmisibilidad tuberculosa en pacientes con TB positivos al VIH que en aquellos negativos al VIH. Las visitas de seguimiento arrojarán una respuesta definitiva sobre dicha hipótesis
