Comparative Study
Psychiatric history and psychologic adjustment as risk factors for aberrant drug-related behavior among patients with chronic pain.
To investigate the role of psychiatric history and psychologic adjustment on aberrant drug-related behavior among patients prescribed opioids for noncancer pain. ⋯ Psychiatric factors, such as a history of mood disorder, psychologic problems, and psychosocial stressors, may place patients at risk for misuse of prescription opioids. Future studies to elucidate the risk of medication misuse and aberrant drug behavior among this patient population are needed.

Randomized Controlled Trial
Thermal and visceral hypersensitivity in irritable bowel syndrome patients with and without fibromyalgia.
Irritable bowel syndrome (IBS) is a chronic gastrointestinal disorder characterized by both visceral and somatic hyperalgesia, producing a similar effect seen with the central hypersensitivity mechanism in fibromyalgia (FM). ⋯ FM+IBS patients show greater thermal hypersensitivity compared with IBS patients. However, IBS patients exhibit higher pain ratings to rectal distension compared with FM+IBS patients. This data suggests that regions of primary and secondary hyperalgesia are dependent on the primary pain complaint.

Assessment of pain in patients with whiplash-associated disorders has been previously reported using a variety of instruments. However, the reproducibility of the findings derived from such measurements has not been explored with respect to this particular patients group. ⋯ On the basis of the current patient sample, this study demonstrates that although PPT findings may generally be applied for monitoring change in chronic whiplash patients, the use of VAS scores should be limited to patients whose initial score is above 4. It is also suggested that if the PPT is to serve as an outcome measure, its measurement should be performed by the same tester.

Randomized Controlled Trial Comparative Study Clinical Trial
Effect of acupuncture-like electrical stimulation on chronic tension-type headache: a randomized, double-blinded, placebo-controlled trial.
The aim of this study was to examine the effect of acupuncture-like electrical stimulation on chronic tension-type headache (TTH) in a randomized, double-blinded, placebo-controlled study. ⋯ The use of acupuncture-like electrical stimulation was not associated with significant adverse effects. These results indicate that acupuncture-like electrical stimulation is a safe and potentially analgesic-sparing therapy that may be considered as an adjunctive treatment for patients with chronic TTH although the clinical effect on pain seems to be marginal in the present set-up.
