The aim of this systematic review was to appraise and analyse the knowledge on bone-related biochemical and histological biomarkers in complex regional pain syndrome 1 (CRPS 1). ⋯ The limited data reviewed revealed certain potential bone-related biomarkers in CRPS. Biomarkers hold the potential to identify patients who may benefit from treatments that influence bone turnover. Thus, this review identifies important areas for future research in CRPS1 patients.

Randomized Controlled Trial
Ultrasound-Guided Percutaneous Electrical Nerve Stimulation versus Surgery for Women with Unilateral Carpal Tunnel Syndrome: A Randomized Parallel-group Trial.
The aim of this clinical trial was to compare the outcomes of the application of ultrasound-guided percutaneous nerve stimulation (PENS) targeting the median nerve versus surgery for improving pain and function in women with CTS. ⋯ The application of percutaneous nerve stimulation was more effective at short-term, but similar effective at mid and long-term, than surgery in women with carpal tunnel syndrome.

Complementary and Integrative Health Approaches (CIHA), including but not limited to, natural products and Mind and Body Practices (MBPs), are promising non-pharmacological adjuvants to the arsenal of pain management therapeutics. We aim to establish possible relationships between use of CIHA and the capacity of descending pain modulatory system in the form of occurrence and magnitude of placebo effects in a laboratory setting. ⋯ Chronic pain participants who use physically oriented mind-body practices, such as yoga and massage, demonstrated attenuated experimentally induced placebo hypoalgesia in comparison with those who do not use them. This finding disentangled the relationship between use of complementary and integrative approaches and placebo effects, providing the potential therapeutic perspective of endogenous pain modulation in chronic pain management.

Prolonged opioid use (more than 90 days) after injury puts the patient at risk for adverse effects. We investigated the patterns of opioid prescription after distal radius fracture and the effect of pre- and post-fracture factors on the risk for prolonged use. ⋯ We show that a common injury such as distal radius fracture can be a gateway to prolonged opioid use, especially among patients with previous history of opioid use or mental illness. Importantly, previous opioid use as far back as 5 years earlier greatly increases the risk of regular use after the reintroduction of opioids. Considering past use is important when planning treatment with opioids. Occupational or physical therapy after injury is associated with lower risk of prolonged use and should be encouraged.

Chronic pain and mental disorders are leading causes of disability worldwide. Individuals with chronic pain are more likely to experience mental disorders compared to individuals without chronic pain, but large-scale estimates are lacking. We aimed to calculate overall prevalence of mental health diagnoses from primary and secondary care among individuals treated for chronic pain in 2019 and to compare prevalence among chronic pain patients receiving opioid versus non-opioid analgesics, according to age and gender. ⋯ This large-scale study with nation-wide registry data supports previous findings of high psychiatric burden in chronic pain patients. Opioid users had significantly higher prevalence of mental health diagnoses, regardless of age and gender compared to users of non-opioid analgesics. Opioid users with chronic pain therefore stand out as a particularly vulnerable group and should be followed up closely by their physician to ensure they receive sufficient care for both their mental and somatic symptoms.
