Randomized Controlled Trial Comparative Study
The relative efficacy of mindfulness versus distraction: The moderating role of attentional bias.
This study investigated whether the ability to disengage quickly from pain-related stimuli moderated the relative efficacy of a mindfulness-based intervention versus distraction in response to an experimental pain task. ⋯ This study demonstrated the efficacy of a novel, exposure-based mindfulness technique for pain tolerance and showed that those who disengaged easily from pain stimuli benefited most. This brief task could be clinically useful, particularly for those who are not overly focused on their pain symptoms.

Pain expectancies are associated with altered pain sensitivity in individuals with chronic pain. However, little is known about the processes by which pain expectancies impact pain processing. This study assessed the association between pain expectancies and temporal summation (TS) of pain, and examined whether pain catastrophizing mediated this association. ⋯ Individuals with chronic low back pain who expect higher levels of pain and catastrophize about their pain are more likely to experience altered pain sensitivity. Our results point to catastrophizing as a mechanism of action through which psychological factors may operate and lead to the development and maintenance of chronic low back pain.

Many neonatal observational pain assessment tools are available. Their application in clinical settings, however, has been limited. A further difficulty for decision makers may be to choose among the variety of available tools the appropriate one(s) for their patients. Aims of the present study were (1) to compare two commonly cited neonatal pain assessment tools, the Neonatal Facial Coding System-Revised (NFCS-R) and the Children and Infant's Postoperative Pain Scale (CHIPPS), with regard to their psychometric qualities and (2) to explore intuitive clinicians' ratings by relating them to the tools' items. ⋯ Psychometric comparisons of neonatal assessment tools provide useful information that can help health care professionals to choose among tools and researchers to improve them. Both tools compared here performed psychometrically equally well. Their clinical utility, however, can be improved, for example by providing a manual (CHIPPS) and training opportunities.

Practice Guideline
Standards for the diagnosis and management of Complex Regional Pain Syndrome: results of a European Pain Federation task force.
Complex regional pain syndrome is a painful and disabling post-traumatic primary pain disorder. Acute and chronic complex regional pain syndrome (CRPS) are major clinical challenges. In Europe, progress is hampered by significant heterogeneity in clinical practice. We sought to establish standards for the diagnosis and management of CRPS. ⋯ This position statement summarizes expert opinion on acceptable standards for CRPS care in Europe.

Amylin is a calcitonin gene-related peptide family member expressed by nociceptors. Amylin's expression is down-regulated following nerve damage, and studies suggested it affects nociception. We aimed at clarifying amylin's effects on chronic neuropathic pain and investigating its site of action. ⋯ Amylin modulated neuropathic pain by acting at different levels of the nervous system. Whereas supraspinal areas may be involved in amylin's induced pronociception, modulation of spinal cord amylin receptors by endogenous or pharmacological amylin doses triggers both pro- and antinociceptive effects.
