Randomized Controlled Trial
Pain Physiology Education Improves Health Status and Endogenous Pain Inhibition in Fibromyalgia: A Double-Blind Randomized Controlled Trial.
There is evidence that education on pain physiology can have positive effects on pain, disability, and catastrophization in patients with chronic musculoskeletal pain disorders. A double-blind randomized controlled trial (RCT) was performed to examine whether intensive pain physiology education is also effective in fibromyalgia (FM) patients, and whether it is able to influence the impaired endogenous pain inhibition of these patients. ⋯ These results suggest that FM patients are able to understand and remember the complex material about pain physiology. Pain physiology education seems to be a useful component in the treatment of FM patients as it improves health status and endogenous pain inhibition in the long term.

Comparative Study
Hypogonadism in Men With Chronic Pain Linked to the Use of Long-acting Rather Than Short-acting Opioids.
There is a need to elucidate the variables associated with testosterone suppression among men on daily opioid therapy for chronic pain. ⋯ Among a contemporary sample of men receiving chronic daily opioids, we found a high prevalence of hypogonadism associated with duration of action, but not with total daily dose of the opioid.

Controlled Clinical Trial
Suppression of Emotion Expression Mediates the Effects of Negative Affect on Pain Catastrophizing: A Cross-Sectional Analysis.
Negative affect is associated with individual differences in pain catastrophizing (PC). Research suggests that variations in emotion regulation may modify negative affect on PC. Using the process model of emotion regulation, this study examined the relationships of 2 emotion regulatory strategies, cognitive reappraisal and expressive suppression, with negative affect and PC. ⋯ These preliminary findings suggest that expressive suppression of emotion plays a mediating role in PC and subsequent pain adjustment outcomes. More research is needed to further examine other types of negative emotions and different emotion regulatory strategies used in chronic pain adjustment.

Comparative Study
Neuropathic Pain Components Are Common in Patients With Painful Cervical Radiculopathy, but Not in Patients With Nonspecific Neck-Arm Pain.
The aim of this study was to investigate, using quantitative sensory testing (QST) parameters and the painDETECT (PD-Q) screening questionnaire, the presence of neuropathic pain (NeP) in patients with unilateral painful cervical radiculopathy (CxRAD) and in patients with unilateral nonspecific neck-arm pain associated with heightened nerve mechanosensitivity (NSNAP). ⋯ QST data suggest that NeP is likely to be observed in patients with painful CxRAD, but not in patients with NSNAP.
