The association of acute pancreatitis with ulcerative colitis [UC] has been described in the literature. It is usually induced by drugs, but sometimes it may be idiopathic. This association remains rare. We report the case of a patient who was treated in our department. Medical observation: Mr. KA, a 60-year-old man, was admitted in our unit for management of acute epigastric. The clinical examination at the admission was normal. After eliminating a cardiac or surgical cause, the diagnosis of acute pancreatitis was made on the basis of the presence of a serum lipase up to 5 times the normal level and pain intensity. An abdominal scanner tomography was performed for the assessment of the pancreatitis. It has shown a pancreatitis stage C associated with a thick rectosigmoidien that was discovered incidentally. Symptomatology was enriched 10 days after by the occurrence of rectal bleeding. A lower endoscopy was performed after the improvement of the pancreatitis and had shown an ulcerative colitis on pancolitis which was confirmed by biopsy. In order to search other causes of this pancreatitis, other tests were made [a biliary IRM, endoscopic ultrasonography, autoimmune tests] and the results were negative. We concluded an idiopathic pancreatitis. The ulcerative colitis was classified as moderate and the patient was put on oral corticosteroids with degression. The evolution was marked by a clinical and biological improvement of pancreatitis and colitis. Conclusion: The association of idiopathic pancreatitis with ulcerative colitis is rare. The case of our patient is the first case reported in our series with 400 cases of ulcerative colitis diagnosed in our service.

Unhealthy behaviors of medical students influence their attitudes toward preventive counseling. The burden of chronic diseases is continually growing in developing countries, emphasizing the need for the increased role of general practitioners in preventive counseling. The objective of this study was to describe the effect of medical training on the risk profiles and attitudes of medical students toward preventive counseling in a Colombian university. Students in their first and fifth years of training were surveyed using the ＂Healthy Doctor = Healthy Patient＂ questionnaire to assess counseling attitudes; personal practices, such as risky drinking, smoking, inadequate nutrition, and non-compliance with physical activity recommendations; and the university environment. The association among these components was estimated, as well as the effect of the university environment. Risky drinking and smoking decreased from first to fifth year （59.3% vs. 37.1%, P = 0.021 and 31.5~ vs. 25.9%, P = 0.51, respectively）, whereas inadequate nutrition and non-compliance with physical activity recommendations increased. Physical activity （PA） was associated with positive counseling attitude （ORs： nutrition 7.6; alcohol 5.2; PA 10.6）. Areas governed by institutional policies that are emphasized in the curriculum positively affected student practices. PA promoted preventive counseling and healthy lifestyles most effectively. Universities should therefore strengthen their preventive medicine curricula and modify social determinants.
