Nonulcer dyspepsia.
Nonulcer dyspepsia, characterized by unexplained persistent or recurrent epigastric pain or discomfort, affects approximately 20% of the general population. Symptom-based diagnostic criteria, first developed by an international group of experts, have been refined in the past year in an effort to increase the applicability of the criteria (Rome II criteria). New disease-specific questionnaires that were developed to measure quality of life in patients with dyspepsia are now available and are expected to be widely used in clinical research studies. Studies on the pathophysiology and management of nonulcer dyspepsia were other major topics in the past year, including three large, well-conducted randomized controlled trials of Helicobacter pylori eradication and symptom resolution.
