[Contributions of endoscopic ultrasound to pancreatic cystic lesions].

Cystic lesions of the pancreas are peculiar in relation to their diagnosis and treatment. The use of endoscopic ultrasonography (EUS) has provided better sensitivity and specificity to differentiate benign from malignant cysts, condition that provides an early diagnosis and an effective and definite treatment.

[Prevalence of rectosigmoid adenomas and adenocarcinomas in patients younger than 50 years old referred for proctorrhagia].

Background: Rectal bleeding is a sign of colorectal cancer (CRC). Its early diagnosis decreases mortality and improves survival. In young population with no risk factors for the disease, CRC is infrequent.

[Detection of polyps, adenomas, advanced adenomas and adenocarcinomas in patients between 45 and 49 years].

Unlabelled: BACKGROUND. Colorectal cancer (CRC) can be prevented. Colonoscopy is the first-line procedure for screening in average risk population.

Management of early-stage esophageal neoplasia (MESEN) consensus.

Background: Treatment of esophageal adenocarcinoma often involves surgical resection. Newer technologies in interventional endoscopy have led to a substantial paradigm shift in the management of early-stage neoplasia in Barrett's esophagus comprising high-grade dysplasia (HGD), intramucosal carcinoma, and, in some cases, submucosal carcinoma. However, there has been no consensus regarding the indications for esophageal preservation in these cases.

Growing up under generalized violence: an ecological study of homicide rates and secular trends in age at menarche in Colombia, 1940s-1980s.

We examined secular changes in mean age at menarche among 5577 Colombian women born between 1941 and 1989, and correlated those changes with nation-wide rates of homicide and real gross domestic product per capita (GDP) at the year of birth and at the year at age 5, within predefined historical periods. The mean (standard error) rate of change in age at menarche by year of birth was -0.55 (0.
