Randomized Controlled Trial Multicenter Study
Single-entity hydrocodone extended-release capsules in opioid-tolerant subjects with moderate-to-severe chronic low back pain: a randomized double-blind, placebo-controlled study.
A single-agent, extended-release formulation of hydrocodone (HC) has been developed for treatment of chronic moderate-to-severe pain. This study was designed to examine the safety and efficacy of HC extended release in opioid-experienced adults with moderate-to-severe chronic low back pain (CLBP). ⋯ Extended-release HC is well tolerated and effective, without acetaminophen-associated risks of liver toxicity, for treatment of CLBP.

Randomized Controlled Trial Multicenter Study
A randomized controlled trial of single point acupuncture in primary dysmenorrhea.
Acupuncture is often used for primary dysmenorrhea. But there is no convincing evidence due to low methodological quality. We aim to assess immediate effect of acupuncture at specific acupoint compared with unrelated acupoint and nonacupoint on primary dysmenorrhea. ⋯ Specific acupoint acupuncture produced a statistically, but not clinically, significant effect compared with unrelated acupoint and nonacupoint acupuncture in primary dysmenorrhea patients. Future studies should focus on effects of multiple points acupuncture on primary dysmenorrhea.

Randomized Controlled Trial
The effect of cognitive load and patient race on physicians' decisions to prescribe opioids for chronic low back pain: a randomized trial.
To test the hypothesis that racial biases in opioid prescribing would be more likely under high levels of cognitive load, defined as the amount of mental activity imposed on working memory, which may come from environmental factors such as stressful conditions, chaotic workplace, staffing insufficiency, and competing demands, one's own psychological or physiological state, as well as from demands inherent in the task at hand. ⋯ Physician gender affected the way in which patient race and cognitive load influenced decisions to prescribe opioids for chronic pain. Future research is needed to further explore the potential effects of physician gender on racial biases in pain treatment, and the effects of physician cognitive load on pain treatment.

In the absence of a suitable reference standard, diagnostic local anesthetic blocks cannot be validated in the manner conventionally used for diagnostic tests. Consequently, diagnostic blocks are vulnerable to criticism for lacking validity, or being "not proven." ⋯ The eight criteria provide an axiomatic, philosophical basis for diagnostic blocks in general, and serve to show what empirical evidence needs to be gathered in order to validate a particular block. The associated metric allows the scientific evidence for different blocks to be quantified and compared.

Randomized Controlled Trial
Pain beliefs predict pain intensity and pain status in children: usefulness of the pediatric version of the survey of pain attitudes.
Pain attitudes and beliefs are hypothesized to influence pain and adjustment to pain. Valid and reliable measures of these beliefs are necessary to test their hypothesized associations with outcomes. The Pediatric version of the Survey of Pain Attitudes (Peds-SOPA) is a new measure with limited evidence regarding its psychometric properties. This study sought to: 1) evaluate the predictive validity, reliability, and factor structure of the Peds-SOPA; and 2) determine if there are sex- or age-related differences in children's attitudes toward pain. ⋯ The current findings provide additional support for the reliability and validity of the Peds-SOPA, and suggest that children's pain attitudes and beliefs might be important intervention targets in pain treatment.
