There is well-established evidence linking adverse childhood experiences (ACEs) and chronic pain in adulthood. It is less clear how ACE exposure might influence the response to chronic pain treatment. In this systematic review, we synthesise the literature assessing the impact of ACE exposure on outcomes relating to the use, benefits, and harms of analgesic medications (analgesia-related outcomes). ⋯ CRD42023389870 (PROSPERO).

Randomized Controlled Trial
Effects of Pulsed Radiofrequency Duration in Patients With Chronic Lumbosacral Radicular Pain: A Randomized Double-Blind Study.
We hypothesized that the duration of pulsed radiofrequency (PRF) application may affect the effectiveness of PRF in patients with chronic lumbosacral radicular pain (LRP). ⋯ The Clinicaltrials.gov registration number under the Clinical Trial Registry of Korea for the study is KCT0003850; https://cris.nih.go.kr.

The role of the complement system in pain syndromes has garnered attention on the back of preclinical and clinical evidence supporting its potential as a target for new analgesic pharmacotherapies. Of the components that make up the complement system, component 5a (C5a) and component 3a (C3a) are most strongly and consistently associated with pain. Receptors for C5a are widely found in immune resident cells (microglia, astrocytes, sensory neuron-associated macrophages (sNAMs)) in the central nervous system (CNS) as well as hematogenous immune cells (mast cells, macrophages, T-lymphocytes, etc.). ⋯ A perspective on the optimal application of different C5a inhibitors for different types (e.g., neuropathic, post-surgical and chemotherapy-induced pain, osteoarthritis pain) and stages (e.g., acute, subacute, chronic) of pain is also provided to help guide future clinical trials. PERSPECTIVE: This review highlights the role and mechanisms of complement components and their receptors in physiological and pathological pain. The potential of complement-targeted therapeutics for the treatment of chronic pain is also explored with a focus on C5a inhibitors to help guide future clinical trials.

Pain is a common presenting symptom to consultant physicians, both in the hospital and in the clinic or rooms. Biologically, pain serves as warning of tissue damage. But this is no longer the case when pain is present for months or years, especially when it has been fully investigated. ⋯ The response to the so-called 'opioid epidemic' has led to a renewed focus on how chronic pain should be managed. The aim of this article is to update fellows and trainees on the assessment and management of chronic pain in adult medical patients. In particular, we address the role of pharmacotherapy post-opioid epidemic (primarily antidepressants and anticonvulsants in neuropathic pain), the place of interventional procedures and the nature and effectiveness of pain self-management training in people with chronic pain, many of whom have had pain for a year or more and failed other treatments.
