Randomized Controlled Trial Multicenter Study
A randomized study of lubiprostone for opioid-induced constipation in patients with chronic noncancer pain.
To evaluate the efficacy and safety of oral lubiprostone for relieving symptoms of opioid-induced constipation (OIC) in patients with chronic noncancer pain. ⋯ Lubiprostone effectively relieved OIC and associated signs and symptoms and was well tolerated in patients with chronic noncancer pain (http://clinicaltrials.gov/ct2/show/NCT00595946).

Multicenter Study Observational Study
The avoidance of activities due to fear of falling contributes to sedentary behavior among community-dwelling older adults with chronic musculoskeletal pain: a multisite observational study.
Physical inactivity and sedentary behavior (SB) are leading causes of mortality. We investigated if older adults with chronic musculoskeletal pain (CMP) are more sedentary than a group of similar age and sex without CMP and possible contributory factors to this. ⋯ Older adults with CMP are significantly more sedentary than those of a similar sex and age without CMP. It appears that the avoidance of activities due to fear of falling is a significant contributory factor to SB in older adults with CMP.

Review Case Reports Multicenter Study
Treatment of medically refractory cancer pain with a combination of intrathecal neuromodulation and neurosurgical ablation: case series and literature review.
Up to 90% of patients with advanced cancer experience intractable pain. For these patients, oral analgesics are the mainstay of therapy, often augmented with intrathecal drug delivery. Neurosurgical ablative procedures have become less commonly used, though their efficacy has been well-established. Unfortunately, little is known about the safety of ablation in the context of previous neuromodulation. Therefore, the aim of this study is to present the results from a case series in which patients were treated successfully with a combination of intrathecal neuromodulation and neurosurgical ablation. ⋯ In cancer patients with medically intractable pain, intrathecal neuromodulation and neurosurgical ablation together may allow for more effective control of cancer pain.

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.
