ABSTRACT
El deporte ha evolucionado a la par de la civilización y hoy es una actividad que involucra a muchos actores, genera pasiones y sustenta un vasto sector de la economía nacional e internacional. Se hace necesario mantener la visión enfocada en los valores que promueve esta actividad y, como sociedad, exigir en cada campeonato la divulgación de sus doctrinas. Diferentes formas de prácticas deportivas se han popularizado y con ello los atletas pueden ser agrupados en aficionados, o de elite. Es decir, los que obtienen resultados locales, nacionales o internacionales, deportistas de alto rendimiento, que están en su mejor forma física y psicológica para competir; y deportistas profesionales, aquellos que prestan sus servicios a cambio de una remuneración. Por último siendo esta una actividad humana debe ser motivo de permanente reflexión ética (1-3).
The sport activity has evolved with civilization and today is an activity that involves many actors, generates passion and supports a vast sector of the national and international economy. Is necessary to keep the focused vision on the values promoted by this activity and, as a society, require in each tournament a disclosure of his doctrines. Different forms of sport have become popular and thus the athletes can be grouped into amateur or elite; into the ones that plays locally, in a nation league or at international level; High performance athletes, who are in their best physical and psychological shape; and professional athletes who provide services in exchange for payment.

Nowadays technics for Helicobacter pylori detection in stools like culture, and PCR, are expensive and difficult to perform. The aim of this study was to evaluate ELISA test efficacy for detection of H. Pylori antigens in stools comparing this results with standarized technics like histology (Giemsa), ureasa test and UBT C 14. 26 patients were evaluated in this study, ages between 15-75 with upper gastrointestinal symptoms; all of them required gastroduodenal endoscopy, status H. Pylori was determined with methods upon mentioned. 24 hours after endoscopy H. Pylori antigens in stools with the technique Premier Platinum Htsa, Elisa were determined. The detection of H. Pylori antigens in stools accurately identified active H. Pylori infection. The performance characteristics of this non-invasive method was similar in sensibility and specificity to conventional tests

El descubrimiento del helicobacter pylori...El objetivo de este estudio fue evaluar en la práctica clínica cotidiana la eficacia e incidencia de efectos adversos de un esquema cuádruple de tratamiento que combina Pantoprazol, Subcitrato de Bismuto Coloidal, Metronidazol y Tetraciclina para la erradicación de la infección por helicobacter pylori....La terapia cuádruple erradicó la infección en cerca del 90 por ciento de los pacientes. Los efectos adversos fueron leves, y no interfirieron con la eficacia del tratamiento ni motivaron abandonos de la medicación. Esta terapia puede ser recomendada, incluso como primera línea de tratamiento

El objetivo de este trabajo fue determinar la tasa de resangrado en pacientes con historia previa de ulcera péptica sangrante H.P. positiva. 42 pacientes hospitalizados por úlceras pépticas sangrante fueron sujetos a tratamiento convencional para el cese de sangrado. Se les efectuó luego taramiento de erradicación del H.P. con triple terapia a 7 días sin mantenimiento posterior. A 4 semanas en el caso de ulcera duodenal y a 6 semanas en casos de ulcera gástrica se comprobó por vía endoscópica e histológica la curación de la úlcera y la erradicación de la bacteria. Los 42 pacientes fueron incluidos en un estudio de seguimiento y al cumplirse 24,02 meses (rango 3-27 meses) no hubo recidiva de la hemorragia en ninguno de ellos. Estos datos sugieren que la erradicación de H.P. puede prevenir la recidiva de sangrado ulceroso en pacientes H.P. positivos.

Mujer de 60 años de edad, con antecedentes de colpoperineorrafia por prolapso vaginal y de cáncer epidermoide cervicouterino EIIB diagnosticado en 1982. La pacientess recibió radioterapia, 7500 rads administrados como teleterapia (ciclo pélvico completo) y braquiterapia con Cesio 137. Diez semanas más tarde se le efectuó una histerectomía tipo Piver II, que se complicó con un absceso en la cúpula vaginal. Doce años después, la paciente presentó metástasis pulmonares y un año más tarde presento en forma súbita, descarga cetrina y salida del epiplón mayor a través de la vagina. A la paciente se le efectuó una plastía vaginal en un plano, por vía abdominal y también se le colocó un colgajo pediculado del epiplón mayor para cubrir la pelvis. La evolución posoperatoria fue satisfactoria

1. During the first two thirds of gestation, coinciding with a minimal accretion by the conceptus, the mother is in an anabolic state which is supported by her hyperphagia and the more efficient conservation of exogenous nutrients when she eats. During this phase maternal fat deposits are accumulated thanks to the enhancement in adipose tissue lipogenic and glycerolgenic activity. In contrast, in the latter part of gestation, the rapid fetal growth is sustained by the intense transfer of nutrients from maternal circulation. 2 Glucose is quantitatively the most abundant of the several substrates that cross the placenta and despite increased maternal gluconeogenesis this transfer is responsible for the maternal tendency to hypoglycemia. This causes a switch to a net catabolic state which is especially evident in the net breakdown of fat depots. 3. Enhanced release of adipose tissue lipolytic products, free fatty acids (FFA) and glycerol, facilitates the liver synthesis of triglycerides and their later release into circulation associated to very low-density lipoprotein (VLDL). Glycerol is also used as an important gluconeogenic substrate and FFAs are broken down through ß-oxidation for ketone body synthesis. Flow through these pathways becomes increased when food is withheld and this actively contributes to the availability of fuels to the fetus which becomes partially preserved from maternal metabolic insult. Increased liver production of VLDL-triglycerides and decreased extrahepatic lipoprotein lipase contribute to exaggerated maternal hypertriglyceridemia which, besides being a floating metabolic reserve for emergency conditions such as starvation, constitutes an essential substrate for milk synthesis around parturition in preparation for lactation. 4. While the maternal anabolic tendencies found during the first two-thirds of gestation seem to be facilitated by hyperinsulinemia in the presence of a normal responsiveness to the hormone, it is proposed that most of the metabolic changes taking place during the last third of gestation seem to be caused by the insulin-resistant state which is consistently present at this stage, since its reversion caused by sustained exaggerated hyperinsulinemia also reverts several of these metabolic adaptations
