Review Meta Analysis
Educational interventions by pharmacists to patients with chronic pain: systematic review and meta-analysis.
We hypothesized that educational interventions delivered by pharmacists to patients with chronic pain might improve pain-related outcomes and sought to establish "proof of concept" for this hypothesis. ⋯ Pharmacist-delivered educational interventions seem to reduce adverse events and improve satisfaction, but their clinical benefit on pain intensity is debatable. Our analysis suggests that the role of pharmacists may be important but a deeper understanding and evaluation of the active components of these interventions is needed within clinical trials before wider implementation into clinical practice can be recommended.

The aim of this study was to give insight in the prevalence of pain, and the (effect of) pain management according to the national emergency medical services analgesia protocol in trauma patients in the Netherlands. ⋯ Prevalence of pain in trauma was high, and without consistent "objective" reporting of pain it is difficult to evaluate the effectiveness of pain management, despite the adherence to clinical practice guideline or protocol. Paramedics need to elicit and report validated pain measurements.

To determine the hypoalgesic effects of transcutaneous electrical nerve stimulation (TENS) parameter combinations on experimental models in healthy humans. ⋯ The level of hypoalgesic efficacy of TENS is clearly dependent on TENS parameter combination selection (defined in terms of intensity, frequency, and stimulation site) and experimental pain model. Future clinical RCTs may consider these TENS dose responses.

Case Reports
Lymphocyte TRPV 1-4 gene expression and MIF blood levels in a young girl clinically diagnosed with HSAN IV.
Patients with congenital insensitivity to pain are unable to sense pain and temperature. They undergo many injuries, inflammatory state, and infections. Various mutations in the neurotrophic tyrosine kinase receptor gene have been implicated in this disorder. We measured the leukocyte expression of transient receptor potential vanilloid (TRPV) 1-4 genes and the blood macrophage migration inhibitory factor (MIF) concentration in a young girl clinically diagnosed with congenital insensitivity to pain. The investigation may help to define the interplay between nerve growth factor and TRPV 1-4 channels and between these sensors and MIF in this disease, and in broader terms in nociception. ⋯ The high increase in the MIF concentration (likely due to the chronic or recurrent inflammatory state) may have contributed to the normal expression of TRPV 1-4 and to the relative upregulation of TRPV1. The role of this cytokine on the expression of these genes deserves further investigation.

The aim of the present study was to describe fear-avoidance beliefs, catastrophizing, and emotional distress among musculoskeletal pain patients in primary healthcare and to explore the relationship of psychological risk profiles for pain, function, and sick leave from baseline through 1-year and 3-year follow-ups. ⋯ Distinct profiles of catastrophizing, fear-avoidance beliefs, and emotional distress were extracted and meaningfully related to future sick leave and dysfunction outcomes. The structures of the profiles were essentially stable and became more accentuated across a 3-year period. The results underscore the need to address psychological aspects as fear-avoidance beliefs, catastrophizing, and emotional distress in the management of patients with musculoskeletal pain and may open the path for a better tailored treatment approach for this patient group.
