P2X7 receptors are responsible for triggering inflammatory responses contributing to processes of pain in articular tissues. This study aimed to investigate whether the activation of the P2X7 receptor located in the temporomandibular joint (TMJ) tissues induces nociception through an inflammatory mechanisms and/or the activation of C-fibres (small-diameter primary afferents) of rats' TMJ. ⋯ The activation of P2X7 receptors has an essential role in TMJ nociception and could be an interesting target to control the inflammatory pain in temporomandibular disorders.

Randomized Controlled Trial Multicenter Study
Effectiveness of a structured group intervention based on pain neuroscience education for patients with fibromyalgia in primary care: A multicentre randomized open-label controlled trial.
There has been increased interest in pain neuroscience education (PNE) as a therapeutic approach for the management of fibromyalgia (FM). ⋯ A structured group intervention based on pain neuroscience education for 1 year in patients with fibromyalgia was associated with significant amelioration of the impact of the disease on scores of the Fibromyalgia Impact Questionnaire, the Health Assessment Questionnaire, the Hospital Anxiety and Depression Scale, the Pain Catastrophizing Scale and the Polysymptomatic Distress Scale as compared with only treatment as usual. These findings are clinically relevant considering the challenges posed by fibromyalgia to clinicians and patients alike.

The vast majority of individuals who come to the emergency department (ED) for care after a motor vehicle collision (MVC) are diagnosed with musculoskeletal strain only and are discharged to home. A significant subset of this population will still develop persistent pain and posttraumatic psychological sequelae may play an important role in pain persistence. ⋯ The first several days after trauma may dictate recovery trajectories. Persistent pain, pain lasting beyond the expected time of recovery, is associated with pain early in the recovery period, but also mediated through other pathways. Future work is needed to understand the complex neurobiological processes in involved in the development of persistent and acute post-traumatic pain.

This paper addresses the question of whether Europe is facing an opioid epidemic and utilizes data from the European monitoring system on opioid use, harms and availability, to help assess the situation. Data sources covering the last decade on overdose deaths, drug treatment entrants and drug-related emergencies suggest that the health burden associated with opioid use is mostly related to the consumption of heroin - and to a lesser extent diverted opioid substitution treatment medications - and that it is primarily affecting an ageing cohort of vulnerable users, with little evidence of an increase in initiation. While opioid-related deaths are currently at much lower levels than in the United States, they still represent a large preventable health burden with differences across EU countries. ⋯ SIGNIFICANCE: This paper looks at data from the European monitoring system to address the question of whether Europe is facing an opioid epidemic. It reviews available health and supply side indicators, considering the limitations of each data source. A summary of the available evidence would suggest that while opioid-related deaths in Europe represent a large preventable health burden with differences across EU countries, Europe as a whole is not facing an opioid crisis of the size and nature seen in the US.
