    This Viewpoint highlights the apparent shift in ulcer epidemiology, with regard to the observed increase in the prevalence of non-Helicobacter pylori, non-NSAID, idiopathic ulcers. The authors recommend that the underlying cause of idiopathic ulcers be investigated further, with rigorous use of diagnostic techniques, and that efforts be made to improve the management and prevention of this condition.

When considering how to treat morbid obesity there are two surgical treatments—laparoscopic adjustable gastric banding and gastric bypass—that go head to head. This Viewpoint examines the safety and efficacy of laparoscopic adjustable gastric banding and gastric bypass for achieving weight loss, and their ability to resolve comorbidities such as type 2 diabetes mellitus.
