This study examined the relationship between the severity of fibromyalgia symptoms and current tobacco use in patients evaluated at a specialized fibromyalgia treatment program. ⋯ Current tobacco use was associated with more severe fibromyalgia symptoms in patients presenting to a specialized fibromyalgia treatment program.

To determine if country (Australia, Taiwan, Singapore), undergraduate healthcare course (physiotherapy, nursing), low back pain (LBP) history, and year of course influenced various back pain beliefs in undergraduate female healthcare students. ⋯ Findings of this study highlight the importance of country, education, and LBP experience on back pain beliefs. The more negative back pain beliefs found in Taiwan and Singapore may reflect current pain beliefs and management attitudes.

The aim of the present study was to investigate the presence of active and latent muscle trigger points (TrPs) in the forearm musculature on both affected and unaffected sides in patients with lateral epicondylalgia (LE) and healthy controls. ⋯ Latent TrPs are present in forearm muscles on the unaffected side in patients with LE where active TrPs contribute to the pain on the affected arm. The presence of latent TrPs on the unaffected side in unilateral LE may be related to central sensitization and be a mechanism explaining bilateral pain in some patients with unilateral pathologies.

We conducted a systematic review to assess the (cost)effectiveness of spinal cord stimulation (SCS) in relieving certain kinds of pain for people with chronic pain owing to failed back surgery syndrome (FBSS). ⋯ For the effectiveness analysis, 1 fully published randomized controlled trial, one randomized controlled trial with 6 month results (both of moderate quality), 1 retrospective cohort study, and 13 case series (all of low quality) were included. The mean period of follow-up was between 6 months and 8.8 years. These studies show that SCS is effective in the treatment of FBSS in terms of pain reduction. The effect was consistent in all analyzed studies. Improvements were also reported for other outcomes, such as quality of life and functional status. All the studies reported some complications, most of which were technical problems. In terms of cost-effectiveness, 3 studies met the inclusion criteria and offered the same conclusion that SCS is both more effective and less costly in the long-term, but there is an initial high cost associated with device implantation and maintenance.

Randomized Controlled Trial
Multiple-day efficacy of parecoxib sodium treatment in postoperative bunionectomy pain.
To determine the analgesic efficacy of 1-day and multiple-day dosing regimens of parecoxib sodium (parecoxib) after bunionectomy in 2 randomized placebo-controlled studies. ⋯ Parecoxib treatment, in conjunction with supplemental analgesia given as needed, provided effective pain relief over 1 to 3 days in the bunionectomy model of postoperative analgesia. Bunionectomy is a useful model for testing multiple-day analgesic therapy.
