Although several pathophysiologic abnormalities have been noted in functional dyspepsia (FD), their pathogenesis is poorly understood. We hypothesized that chronic gastric hypersensitivity and gastric motor dysfunction seen in FD patients can be modeled in rats by transient gastric irritation during the neonatal period, a time of known neuronal vulnerability to long-term plasticity. ⋯ These studies demonstrate that gastric irritation in the neonatal period can result in chronic gastric hypersensitivity and gastric motor dysfunction in adults even in the absence of significant detectable gastric pathology. Our results offer insight into the pathogenesis of chronic functional dyspepsia and provide a potential model for further study to this important clinical problem.

Randomized Controlled Trial Comparative Study
Resection vs drainage in treatment of chronic pancreatitis: long-term results of a randomized trial.
Tailored organ-sparing procedures have been shown to alleviate pain and are potentially superior in terms of preservation of endocrine and exocrine function as compared with standard resection (Whipple) for chronic pancreatitis with inflammatory pancreatic head tumor. Long-term results comparing these 2 procedures have not been published so far. The aim of this study was to report on long-term results of a randomized trial comparing a classical resective procedure (pylorus-preserving Whipple) with an extended drainage procedure (Frey) for chronic pancreatitis. ⋯ Both procedures provide adequate pain relief and quality of life after long-term follow-up with no differences regarding exocrine and endocrine function. However, short-term results favor the organ-sparing procedure.

Comparative Study
The relative efficacies of gastroprotective strategies in chronic users of nonsteroidal anti-inflammatory drugs.
There are numerous gastroprotective strategies recommended for reducing the risk of upper gastrointestinal (GI) complications in long-term users of nonsteroidal anti-inflammatory drugs (NSAIDs). The relative efficacy of the different strategies alone or in combination is uncertain. ⋯ All of the commonly accepted gastroprotective strategies reduce the risk of upper GI complications in NSAID users, although the combination of COX-2 inhibitors with PPIs promotes the greatest risk reduction for NSAID-related upper GI complications. Celecoxib use specifically may be superior to the combination of nonselective NSAIDs with a PPI.
