Introduction: Erectile dysfunction is highly prevalent in the population and vascular and neural processes are involved in its pathophysiology, including those related to late complications of diabetes mellitus. Objective: To determine the association between diabetes mellitus and corpus cavernosum arterial insufficiency in patients with erectile dysfunction. Methods: Cross-sectional study of secondary data analysis conducted in a private health facility in Lima during the year 2022. Patients with a confirmed diagnosis of erectile dysfunction were included. The independent variable was the diagnosis of diabetes mellitus and the dependent variable was the diagnosis of corpus cavernosum arterial insufficiency. Association statistics were performed and prevalence ratios were estimated using logistic regression. Results: Of 887 patients, the mean age was 48.5 years. In the bivariate analysis...

OBJETIVO: Determinar la frecuencia de litiasis vesicular en pacientes post-operados con gastrectomía por adenocarcinoma gástrico, determinar el tiempo de aparición de litiasis vesicular en pacientes gastrectomizados por Adenocarcinoma Gástrico. MÉTODOS: Se realizo un estudio observacional, descriptivo retrospectivo. Se revisó un total de 148 historias clínicas de pacientes sometidos a gastrectomía por adenocarcinoma gástrico en el Instituto Nacional de Enfermedades Neoplásicas en el periodo de 1990 al 2000. RESULTADOS: De los 148 casos de pacientes post gastrectomizados por adenocarcinoma gástrico que fueron enrolados, 29(19.6%) presentaron litiasis vesicular versus 119(80.9%) que no presentaron litiasis vesicular como complicación post gastrectomía. La media de edad de 29 pacientes con litiasis vesicular post gastrectomía por adenocarcinoma gástrico fue de 59.9años (min....

In the developing world, most patients with hepatocellular carcinoma present with advanced-stage disease, considered to be incurable based on current therapeutic algorithms. Here, we demonstrate that curative liver resection is achievable in a portion of Peruvian patients not addressed by these treatment algorithms. We conducted a retrospective cohort study of 253 hepatocellular carcinoma patients that underwent a curative hepatectomy between 1991 and 2011 at the National Cancer Institute of Peru. The median age of the cohort was 36 years, and merely 15.4% of the patients displayed cirrhosis. The average tumor size was over 14 cm in diameter, resulting in 76.3% of major hepatectomies performed. The 5- and 10-year survival probability estimates were 37.5% and 26.2%, respectively. Age (>44 vs. ≤44 years old; P = 0.005), tumor size (>10 cm vs. ≤10 cm in diameter; P = 0.009), cirrhosis (...
