Revista Espa?ola de Enfermedades Digestivas , 2012,
Abstract: Background and aims: ERCP during pregnancy is always challenging for the entire team performing the endoscopic intervention. In this study techniques and different interventional aspects used at several centres about the clinical experience on ERCP in pregnant women are analyzed. Patients and methods: the practice on ERCP in pregnant women in six centers during a period of ten years is reported. Results: eleven patients were included in the study. Mean age was 30.6 years. Indication for ERCP was always symptomatic common bile duct stone (CBDS) disease. Before the procedure abdominal ultrasound was performed at all times and magnetic resonance cholangiopancreatography in four occasions. Conscious sedation by means of midazolam and fentanyl or meperidine was applied. Sphincterotomes and guidewires were used for bilary cannulation. Sometimes, rapid exchange platforms with short-length guidewires controlled by the same endoscopist were employed. Biliary cannulation was confirmed in 9 occasions by bile aspiration. In five procedures, a mean of 30 seconds of fluoroscopy was used, both to verify cannulation and to corroborate complete CBDS clearance. These patients had the pelvic zone protected with a lead shield and radiation dose was measured. Ten biliary sphincterotomies were performed followed by CBDS extraction. Two plastic stents were inserted. Relief of biliary obstruction was attained in all circumstances. Only one patient had hyperamylasemia after ERCP. All pregnant women had healthy foetuses with normal deliveries. Conclusions: with experience, ERCP appears to be a safe technique during pregnancy. With simple measures fluoroscopic time can be diminished or even abolished. It seems that ERCP during pregnancy is underused in our working areas, although it has shown to be a useful technique for relieving biliary obstruction. Antecedentes y objetivos: la CPRE realizada durante el embarazo constituye siempre un reto para todo el equipo que participa en la intervención endoscópica. En este estudio se analizan los diferentes aspectos y técnicas en varios centros sobre la experiencia clínica de la CPRE realizada en mujeres gestantes. Pacientes y métodos: experiencia en seis centros sobre las CPRE en embarazadas durante 10 a os. Resultados: se incluyeron 11 pacientes con edad media de 30,6 a os. La indicación fue siempre coledocolitiasis sintomática. Antes de la CPRE se realizó ecografía abdominal en todos los casos y colangiorresonancia en 4. Se utilizó sedación consciente con midazolam y fentanilo o meperidina. Para la canulación biliar se utilizaron esfinte

Abstract: an overvew of the historical development of limnology in colombia since the decade of the seventies was made. the biological and physicochemical characteristics of different aquatic ecosystems and the assessesment of how much information have been gatered is analized. the knowledge of limnology in colombia is based on information of the most relevant existing literature. it concludes, that certainly in the last four decades has made great efforts to know the physical and chemical characteristics of our aquatic ecosystems and their flora and fauna associated with them. however, still there are too much work to do in all fields of limnology.

Abstract: Se hace un recorrido del desarrollo histórico de la limnología en Colombia a partir de la década de los a os setenta. Se analizan las características biológicas y fisicoquímicas de los diferentes ecosistemas acuáticos y se valora qué tanta información se tiene de cada uno de ellos. El conocimiento que se tiene de la limnología en Colombia se apoya en la información bibliográfica existente más relevante. Se llega a la conclusión, que sin duda en los últimos cuatro décadas se ha hecho un gran esfuerzo para conocer las características físicas y químicas de nuestros ecosistemas acuáticos y de su flora y fauna asociados a ellos. Sin embargo, aún falta mucho trabajo por realizar en todos campos de la limnología. An overvew of the historical development of limnology in Colombia since the decade of the seventies was made.

Revista Colombiana de Psiquiatría , 2011,
Abstract: Introducción: Este trabajo examina la percepción de hechos violentos en la televisión colombiana por parte de escolares bogotanos entre siete y doce a os de edad, de los estratos socioeconómicos 2, 3 y 4. Método: Los autores realizaron l90 entrevistas y dos grupos focales. Para el análisis se buscó entender los factores más relevantes que inciden en la percepción de la violencia en la televisión. Resultados: Los ni os invierten en promedio cuatro horas diarias frente a la televisión, mientras que las actividades lúdicas y de diálogo con los padres son escasas; además, identifican la violencia en la televisión. El 61% de los ni os está expuesto a los contenidos de los programas emitidos por la televisión sin la guía o compa ía de otra persona durante las horas diurnas posteriores a su jornada escolar. El 62% afirma no imitar conductas o aptitudes de los personajes presentados en los programas televisivos. El 75% de los ni os reportó peleas frecuentes entre los miembros de la familia. Conclusión: Es aquí pertinente se alar para la discusión que entre los ni os estudiados concurren factores de riesgo para el uso de modelos de violencia: el elevado número de horas en que ven solos la televisión y la incidencia alta de violencia en el entorno familiar. Los padres aparecen en el estudio como la mayor fuente de agresión hacia los ni os, mientras que las expresiones de afecto y la actividad lúdica con ellos son escasas. Este contexto de consumo de la televisión ofrece entonces, mayores riesgos para incorporar guiones agresivos. Introduction: This paper examines the perception of violence in Colombian television, by school between seven and twelve years of age, socioeconomic stratum two, three and four. Method: The authors made 190 interviews and two focus groups. The analysis sought to understand the most important factors affecting the perception of violence on TV. Results: Children spend an average of four hours per day watching television, while leisure activities and dialogue with parents is low, also identified in the TV violence. 61% of children are exposed to the content of programs broadcast by television without the guidance of another person or company during the day after the school. The 62% say don′t imitate behaviors or attitudes of the characters presented in television programs, 75% of children reported frequent fights between family members. Conclusion: it is pertinent to note here for the discussion, among the children studied concur a risk factors for the use of patterns of violence: The high number of hours that go alone to the television, al
