Aims The aim of this study was to characterize the patient population of this clinic to understand needs and inform future service development for pediatric chronic pain. Methods Demographics and disease characteristics of all patients seen in this clinic between October 1, 2015, and February 28, 2019, were analyzed retrospectively from electronic medical records. Results A total of 157 patients, mean age 13.1 (sd ±3.0) years, 75.2% female, with a median duration of pain of 20.5 (interquartile range [IQR] = 10.0–45.8) months at their first visit were included in the study. At baseline, 74.0% of patients experienced insomnia, 76.6% fatigue, 86.5% symptoms of anxiety, and 58.69% symptoms of depression; 80.1% showed withdrawal from physical activity, 67.1% missed school, and 10.2% reported opioid usage. Throughout their care in clinic, 83.4% of patients received physiotherapy, 17.8% occupational therapy, 49.7% mental health support, and 51.6% care from multiple services. The clinic experienced a significant increase in median referrals from 1.0 to 5.0 (IQR = 2.0–9.0) per month and wait time from 35.0 to 97.0 (IQR = 88.0–251.0) days during the observation period. Conclusions Developing an interdisciplinary service for pediatric chronic pain will provide an opportunity to improve access, coordination, and comprehensiveness of care and to employ culturally sensitive services to improve care for children and youth living with chronic pain in Manitoba and possibly other jurisdictions with similar demographics and needs.","PeriodicalId":53214,"journal":{"name":"Canadian Journal of Pain-Revue Canadienne de la Douleur","volume":" ","pages":"124-134"},"PeriodicalIF":2.4,"publicationDate":"2022-08-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9389926/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40413647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seminal work from various laboratories has shown that differing inflammatory responses underlie some of the sexual dimorphism observed in the regulation of pain. While it is now clear that interactions between the nervous and immune systems are critical mediators of both acute and chronic pain responses, the underlying molecular and cellular mechanisms controlling these differences remain poorly understood. We will present evidence from our respective laboratories showing how sexually dimorphic responses in neuroimmunity help control pain using models of multiple sclerosis (Dr. Bradley Kerr), complex regional pain syndrome (Dr. Vivianne Tawfik), and in the baseline control of nociception (Dr. Nader Ghasemlou). Abstract Activated myeloid-lineage cells, macrophages peripherally and microglia centrally, contribute to the acute-to-chronic pain transition, however, the details on the timing and possible sex-specificity of such involvement remains a matter of debate. For example, there is evidence that CNS microglia may contribute to chronic pain only in males. In this talk I will discuss data from my laboratory using complementary pharma-cologic and transgenic approaches in mice to more specifically manipulate myeloid-lineage cells using a model of the pain condition, complex regional pain syndrome. I will discuss a novel spatiotemporal transgenic mouse line, Cx3CR1-Cre ERT2 -eYFP;TLR4 fl/fl (TLR4 cKO) that we used to specifically knock out toll-like receptor 4 (TLR4), only in microglia and no other myeloid-lineage cells. Using this transgenic mouse, we find that early TLR4 cKO results in profound improvement in chronic, but not acute, allodynia in males, with a significant but less robust effect in females. In contrast, late TLR4 cKO results in partial improvement in allodynia in both sexes, suggesting that downstream cellular or molecular TLR4-independent events may have already been triggered. I will further discuss new data using a transgenic mouse that allows for microglia-specific depletion, Cx3CR1-Cre ERT2 -eYFP;iDTR lox-STOP-lox (microglia cKO). We performed microglial depletion at multiple time points after peripheral injury and see the most striking decrease in mechanical allodynia in males and females when depletion is performed several weeks after injury.

Still in its infancy, cross-sectional work has identified the presence of various memory biases in adults living with chronic pain, one of which concerns the lack of spatiotemporal specificity.
