Case ReportsHyaluronic acid injections for treatment of pediatric sickle cell avascular necrosis of the humeral head.
Avascular necrosis (AVN) can impact up to 50% of patients with sickle cell disease (SCD) and can result in significant pain, decline in physical function and decreased quality of life. While hyaluronic acid (HA) has been used in the adult population for shoulder osteoarthritic pain, we present the first published pediatric case of HA injections in the glenohumeral joint, used to improve function and pain control. ⋯ Conservative options to improve functioning and pain are especially important in pediatric patients where it may be desirable to delay surgical interventions until skeletal maturity. Our case report demonstrates the benefits of intra-articular HA as part of a multidisciplinary pain management plan to improve function and decrease pain related to AVN of the humeral head. Future studies should assess the long-term benefits of HA injections for AVN in the setting of SCD.

ReviewModulatory Effects of Stem Cells on Opioid Receptors and Neuroinflammation.
This narrative review examines stem cell therapy and its effect on opioid therapy in neuropathic pain. ⋯ Stem cell therapy has shown promise in neuropathic pain and opioid tolerance, with a notable common pathway (the P2X4 receptor). Opioid therapy frequently has poor efficacy in patients who suffer from neuropathic pain. There is evidence that the presence of neuropathic pain itself causes changes to the opioid receptor, decreasing the therapeutic potential of this modality. The efficacy of opioid therapy is further decreased in this patient population after chronic opioid exposure, which leads to opioid tolerance and in some cases opioid-induced hyperalgesia. There is growing evidence that stem cell therapy has potential to treat neuropathic pain and may simultaneously decrease opioid tolerance and hyperalgesia. Opioid-induced hyperalgesia occurs via mu-opioid receptor-dependent expression of P2X4 receptors on microglia. Intrathecal stem cell therapy provides analgesic properties due to the significant reduction of P2X4R expression in spinal cord microglia, thereby directly decreasing chronic neuropathic pain.

The COVID-19 pandemic has forced sweeping social and behavioral changes that have adversely affected the general population. Many changes, such as business closures, working from home, increased psychological distress, and delayed access to health care, could have unique adverse effects on patients diagnosed with chronic pain (CP). The present study sought to examine perceived changes in the CP experience brought about by the COVID-19 pandemic. ⋯ For frontline treatment providers, particularly primary care nurses and physicians, these findings may be relevant in order to reduce the likelihood of a worsening of symptoms, loss of self-efficacy regarding management of pain and/or potential maladaptive increase in the use of pain medications.

Observational Study
Five-year Observational Study of Internet-Delivered Cognitive Behavioural Pain Management when offered as Routine Care by an Online Therapy Clinic.
Internet-delivered cognitive behavioural pain management programmes (PMPs) are effective, but less is known about their use outside of research trials. Five years of data from offering the Internet-delivered cognitive behavioural PMP in an online therapy clinic was examined to assess effectiveness, acceptability and predictors of outcomes. ⋯ This 5-year observational study provides support for Internet-delivered cognitive behavioural pain management programs (PMPs) offered as routine care in an online therapy clinic. Interest in the service grew over 5 years. Outcomes, engagement and satisfaction were strong. Higher pain acceptance, pain self-efficacy and lower pain severity were associated with greater post-treatment improvements on depression, anxiety and disability.

The current study aimed to investigate the patterns of postoperative pain trajectories over time and their associated risk factors in patients receiving video-assisted thoracoscopic surgery (VATS) and epidural analgesia (EA) for non-small cell lung cancer (NSCLC). ⋯ Surgical time, sex, and pain intensity after surgery were major determinants of rebound pain trajectory, and more aggressive pain control strategies should be considered in high-risk patients.
