The study of psychosocial risk factors of pain among employees has typically focused on Karasek's job-demand-control model. The aim of the study was to examine the own and independent associations of job strain, organizational justice, workplace bullying, and work-home interface with pain. Data were collected through a postal survey to all 40, 45, 50, 55, and 60-year-old employees of the City of Helsinki in 2001 and 2002 (response rate 66%, N=5819, 80% women). ⋯ Job strain and organizational justice showed associations with chronic pain. Future studies would benefit from a broad psychosocial framework. Investments to healthier psychosocial working environments are needed to tackle pain related problems among employees.

Review Meta Analysis
Acupuncture and dry needling in the management of myofascial trigger point pain: a systematic review and meta-analysis of randomised controlled trials.
Pain from myofascial trigger points is often treated by needling, with or without injection, although evidence is inconclusive on whether this is effective. We aimed to review the current evidence on needling without injection, by conducting a systematic literature review. We searched electronic databases to identify relevant randomised controlled trials, and included studies where at least one group were treated by needling directly into the myofascial trigger points, and where the control was either no treatment, or usual care; indirect local dry needling or some form of placebo intervention. ⋯ In conclusion, there is limited evidence deriving from one study that deep needling directly into myofascial trigger points has an overall treatment effect when compared with standardised care. Whilst the result of the meta-analysis of needling compared with placebo controls does not attain statistically significant, the overall direction could be compatible with a treatment effect of dry needling on myofascial trigger point pain. However, the limited sample size and poor quality of these studies highlights and supports the need for large scale, good quality placebo controlled trials in this area.

Review Meta Analysis
Summary measures of number needed to treat: how much clinical guidance do they provide in neuropathic pain?
Several systematic reviews of randomized controlled trials (RCTs) of drugs to treat neuropathic pain have reported summary estimates of efficacy - specifically, the number needed to treat (NNT). ⋯ Summary NNT estimates may have limited clinical relevance, due to problems of heterogeneity. The most that can be extracted from systematic reviews published to date is the identity of drugs that have demonstrated efficacy for specific types of neuropathic pain, and the strength of such evidence.

Review Multicenter Study
Biphosphonates for the therapy of complex regional pain syndrome I--systematic review.
Several studies found that biphosphonates counteract locally increased bone resorption and associated pain in patients with complex regional pain syndrome I (CRPS I). We performed a systematic review of all randomised controlled trials to assess the benefit of biphosphonates in the treatment of CRPS I patients with bone loss. ⋯ The very limited data reviewed showed that bisphosphonates have the potential to reduce pain associated with bone loss in patients with CRPS I. However, at present there is not sufficient evidence to recommend their use in practice.

Randomized Controlled Trial Multicenter Study
A randomised controlled trial with prolonged-release oral oxycodone and naloxone to prevent and reverse opioid-induced constipation.
Opioid-induced constipation can have a major negative impact on patients' quality of life. This randomised, double-blinded study evaluated the analgesic efficacy of prolonged-release (PR) oral oxycodone when co-administered with PR oral naloxone, and its impact on opioid-induced constipation in patients with severe chronic pain. Another objective was to identify the optimal dose ratio of oxycodone and naloxone. ⋯ Co-administration of PR oral naloxone and PR oral oxycodone is associated with a significant improvement in bowel function compared with PR oral oxycodone alone, with no reduction in the analgesic efficacy of oxycodone.
