Objectives: Liver transplantation is the treatment of choice for acute and chronic liver failure, for selected cases of tumors, and for conditions resulting from errors in metabolism. This paper reports the experience of a medical center in Latin America.Methods: Were conducted 305 orthotopic liver transplantations on 284 patients between 2004 and 2010. Of these patients, 241 were adults undergoing their first transplantation.Results: The average age of patients was 52 years old, and 62% of the individuals were male. The most common indication was alcoholic cirrhosis. The rate of patient survival after 1 and 5 years was 82 and 72% respectively. The rate of liver graft survival after 1 and 5 years was 78 and 68% respectively. The main cause of death was sepsis. Complications in the hepatic artery were documented for 5% of the patients. Additionally, 14.5% of the patients had complications in the biliary tract. Infections were found in 41% of the individuals. Acute rejection was observed in 30% of the subjects, and chronic rejection in 3%. Conclusion: In conclusion, liver transplantation at our medical center in Colombia offers good mid-term results, with a complication rate similar to that reported by other centers around the world.

Introducción: El prolapso de órganos pélvicos es infrecuente durante el embarazo y se asocia principalmente a mujeres multíparas. Dado que la población gestante no es la ideal para manejo quirúrgico, los pesarios son útiles para controlar los síntomas con pocos efectos adversos y contraindicaciones. Por su baja incidencia, la información reportada en la literatura se deriva de reportes de caso y las recomendaciones se extrapolan de pacientes no embarazadas. Metodología: Revisión de la literatura y exposición de casos. Resultados: Se exponen cuatro casos de gestantes con prolapso de órganos pélvicos manejadas exitosamente con pesarios hasta el final de la gestación sin presentar complicaciones serias. Conclusiones: Los pesarios son un método seguro y eficaz para el manejo de síntomas de prolapsos de órganos pélvicos durante el embarazo.

a b s t r a c tThe paper examines the effects of five major socialization agents-namely parents, peers, traditional media, the Internet, and music industry-on emerging adults' attitudes and behavior toward music piracy in the form of unauthorized downloading. Based upon self-reported behavior, our study shows that these socialization agents exert differential effects on music piracy. Specifically, peers and the Internet exert direct impact on both attitudes and behavior. Parents and music industry, however, only have indirect impact on emerging adults' piracy behavior through shaping their attitudes. The research further shows that the effects of socialization agents differ across consumer segments. A factor mixture modeling technique is first applied to disentangle the behavioral heterogeneity, and more observable factors such as demographic, social, and psychological variables are then utilized to profile members in each segment. From a managerial perspective, this research provides new avenues for managers and policy makers to design targeted prevention programs to curtail music piracy.Published by Elsevier B.V.Decision Support Systems 69 (2015) 70-81 ⁎ Corresponding author.
