Review Comparative StudyBalancing the gastrointestinal benefits and risks of nonselective NSAIDs.
Nonselective nonsteroidal anti-inflammatory drugs (NSAIDs) are among the most widely used classes of medications to treat pain and inflammation. However, gastrointestinal complications associated with NSAIDs are prevalent, largely due to the frequent use of these agents. Adverse events associated with NSAIDs include minor side effects, such as dyspepsia, as well as serious complications, such as bleeding and perforation. ⋯ Side effects such as dyspepsia do not provide adequate warning of gastrointestinal complications, because most complications occur without the presence of antecedent symptoms. Therefore, accurate risk assessment and the management of controllable risk factors are crucial to the safe administration of NSAIDs. This review focuses on the gastrointestinal effects of aspirin, acetaminophen, and other nonselective NSAIDs, and discusses those factors that are associated with increased risk for adverse gastrointestinal events in certain individuals.

ReviewWhat should be the core outcomes in chronic pain clinical trials?
A consensus conference with representatives from academia, governmental agencies, and the pharmaceutical industry met and concluded that clinical trials designed to assess the efficacy and effectiveness of treatments for chronic pain should consider outcomes in six core domains: pain, physical functioning, emotional functioning, patient global ratings of satisfaction, negative health states and adverse events, and patient disposition. In addition, it was acknowledged that there are many secondary domains that might be of importance and should be included in trials depending on the nature of the treatment and population to whom the treatment is targeted.

ReviewPsychological stress and fibromyalgia: a review of the evidence suggesting a neuroendocrine link.
The present review attempts to reconcile the dichotomy that exists in the literature in relation to fibromyalgia, in that it is considered either a somatic response to psychological stress or a distinct organically based syndrome. Specifically, the hypothesis explored is that the link between chronic stress and the subsequent development of fibromyalgia can be explained by one or more abnormalities in neuroendocrine function. There are several such abnormalities recognised that both occur as a result of chronic stress and are observed in fibromyalgia. Whether such abnormalities have an aetiologic role remains uncertain but should be testable by well-designed prospective studies.
