HIV-associated sensory neuropathy (HIV-SN) is a common neurological complication of HIV infection, and it is often painful. Tumor necrosis factor (TNF)-α is implicated in neuropathic pain, but associations between neuropathic pain and polymorphisms in the TNFA gene have not been identified. The "TNF block" is a region of high linkage disequilibrium within the central major histocompatability complex that contains several genes involved in the regulation of inflammation, including TNFA. Polymorphisms in the block have been associated with an altered risk of HIV-SN, but no investigations into whether this region is associated with the painful symptoms of neuropathy have been undertaken. Therefore, we investigated whether polymorphisms in the TNF block are associated with pain intensity in black Southern Africans with HIV-SN. ⋯ We identified a novel genetic association between polymorphisms in the TNF block and the pain intensity in black Southern Africans with HIV-SN. Our study implicates rs28445017 in painful HIV-SN, although its precise role and whether it may be causative is unclear. rs28445017 was not associated with the risk for HIV-SN as such, highlighting potential differences between the pathophysiology of the neuropathy and the painful features of the neuropathy.

Opioid-induced pruritus is a common side effect of opioid treatment in patients with acute pain associated with surgery or childbirth. There are several options available to treat opioid-induced pruritus, including nalbuphine. However, it is not known whether nalbuphine offers greater efficacy in treating pruritus without attenuation of analgesia and an increase in the incidence of adverse outcomes. ⋯ Nalbuphine is superior in treating opioid-induced pruritus when compared with placebo, control, diphenhydramine, naloxone, or propofol in patients receiving neuraxial opioids for acute pain related to surgery or childbirth. Therefore, it is recommended that nalbuphine should be used as a first-line treatment of opioid-induced pruritus.

Randomized Controlled Trial
Effects of a Tailored Positive Psychology Intervention on Well-being and Pain in Individuals with Chronic Pain and a Physical Disability: A Feasibility Trial.
To determine the feasibility, acceptability, and efficacy of a computer-based positive psychology intervention in individuals with a physical disability and chronic pain. ⋯ The results support the feasibility, acceptability, and potential efficacy of a computer-based positive psychology intervention for improving well-being and pain-related outcomes in individuals with physical disabilities and chronic pain, and indicate that a full trial of the intervention is warranted.

Randomized Controlled Trial Pragmatic Clinical Trial
Acupuncture Reduces Pain and Autonomic Distress During Injection of Local Anesthetic in Children - A Pragmatic Crossover Investigation.
Stimulation of acupoint LI4 has been shown to result in analgesic effects in patients experiencing acute pain. We aimed to study the effectiveness of LI4 stimulation for pain relief in children receiving an injection of a local anesthetic (LA). ⋯ Stimulation of acupoint LI4 reduces pain and autonomic distress in children during LA injection in dental procedures.

Adolescents with juvenile fibromyalgia (JFM) are typically sedentary despite recommendations for physical exercise, a key component of pain management. Interventions such as cognitive-behavior therapy (CBT) are beneficial but do not improve exercise participation. The objective of this study was to obtain preliminary information about the feasibility, safety, and acceptability of a new intervention--Fibromyalgia Integrative Training for Teens (FIT Teens), which combines CBT with specialized neuromuscular exercise training modified from evidence-based injury prevention protocols. ⋯ Results of this study provided initial support for the new FIT Teens program. An integrative strategy of combining pain coping skills via CBT enhanced with tailored exercise specifically designed to improve confidence in movement and improving activity participation holds promise in the management of JFM.
