Prevalence and perceptions of e-cigarette use among medical students in a Saudi University.

Background And Aims: We hypothesized that the prevalence of electronic cigarette vaping among the medical student population is on the rise. Our aims were to assess the prevalence of electronic cigarette vaping among medical students in Saudi Arabia, to understand and analyze the reasons that led them to try it, and to investigate students' perceptions towards electronic cigarette vaping.

Methods: An anonymous, paper-based, cross-sectional questionnaire was distributed amongst 401 undergraduate medical students from years 1-5 at Alfaisal University in Riyadh, Saudi Arabia.

Retrograde Pancreatic Duct Stent Migration into the Biliary Tract Presenting as a Rare Early Complication of Pancreaticoduodenectomy (Whipple Procedure).

BACKGROUND Pancreaticoduodenectomy (Whipple procedure) is an established surgical procedure for the treatment of carcinoma of the head of the pancreas. Modifications to this procedure include gastropancreaticoduodenectomy, which includes the removal of parts of the pancreas, duodenum, and stomach.
