To determine whether individuals who use prescribed opioids for chronic noncancer pain have higher rates of any opioid misuse, any problem opioid misuse, nonopioid illicit drug use, nonopioid problem drug use, or any problem alcohol use, compared with those who do not use prescribed opioids. ⋯ Users of prescribed opioids had higher rates of opioid and nonopioid abuse problems compared with nonusers of prescribed opioids, but these higher rates appear to be partially mediated by depressive and anxiety disorders. It is not possible to assign causal priority based on our cross-sectional data, but our findings are more compatible with mental disorders leading to substance abuse among prescription opioid users than prescription opioids themselves prompting substance abuse iatrogenically. In patients receiving prescribed opioids, clinicians need to be alert to drug abuse problems and potentially mediating mental health disorders.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy and safety of the fentanyl iontophoretic transdermal system (ITS) and intravenous patient-controlled analgesia (IV PCA) with morphine for pain management following abdominal or pelvic surgery.
The fentanyl HCl iontophoretic transdermal system (ITS) has effectively managed pain following several types of surgery. This study evaluated the efficacy, safety, and ease of care associated with fentanyl ITS and morphine intravenous patient-controlled analgesia (IV PCA) for pain management following abdominal or pelvic surgery. ⋯ Fentanyl ITS and morphine IV PCA were comparable methods of pain control following abdominal or pelvic surgery; however, fentanyl ITS was rated better than morphine IV PCA for ease of care by patients and nurses.

Randomized Controlled Trial
The effect of anxiety and depression on improvements in pain in a randomized, controlled trial of pregabalin for treatment of fibromyalgia.
To assess symptoms of anxiety and depression in a large cohort of fibromyalgia patients and to determine the impact of these symptoms on response of pain to pregabalin treatment. ⋯ Anxiety symptoms were more common than depressive symptoms in this cohort. Our results suggest patients with fibromyalgia should be routinely assessed for the presence of both anxiety and depression. The pain treatment effect of pregabalin did not depend on baseline anxiety or depressive symptoms, suggesting pregabalin improves pain in patients with or without these symptoms. Much of the pain reduction appears to be independent of improvements in anxiety or mood symptoms.

Reflexive responses to pain such as facial reactions become increasingly important for pain assessment among patients with Alzheimer's disease (AD) because self-report capabilities diminish as cognitive abilities decline. Our goal was to study facial expressions of pain in patients with and without AD. ⋯ This is the first study to discriminate among FACS measures collected during innocuous and graded levels of precisely measured painful stimuli in seniors with (mild) dementia and in healthy control group participants. We conclude that, as hypothesized, FACS can be used for the assessment of evoked pain, regardless of the presence of AD.

This study was conducted to test the hypothesis that gender differences in physical and emotional functioning are present among patients with fibromyalgia undergoing multidisciplinary pain rehabilitation. ⋯ These results support the hypothesis that pretreatment gender differences are present among fibromyalgia patients undergoing multidisciplinary pain rehabilitation and post-treatment gender differences persist despite improvements in physical and emotional functioning.
