Chronic neuropathic pain is often refractory to conventional medical treatments and leads to significant disability and socio-economic burden. Dorsal root ganglion (DRG) stimulation has recently emerged as a treatment for persistent neuropathic pain, but creating a strain relief loop at the S1 level has thus far been a challenging technical component of DRG lead placement. ⋯ The patient experienced a decrease in visual analog pain score (85%), and improvement in function during the trial period, and proceeded with permanent implantation. The described sacral transforaminal strain relief loop formation technique appears to be a more reliable and predictable technique of DRG lead placement in the sacrum than those previously documented.

Randomized Controlled Trial
Treatment With Naloxegol Versus Placebo: Pain Assessment in Patients With Noncancer Pain and Opioid-Induced Constipation.
To summarize results from pain and opioid use assessments with naloxegol in adults with opioid-induced constipation (OIC) and chronic noncancer pain. ⋯ Centrally mediated opioid analgesia was maintained during treatment with naloxegol in patients with noncancer pain and OIC.

Randomized Controlled Trial Multicenter Study
Effects of Median Nerve Neural Mobilization in Treating Cervicobrachial Pain: A Randomized Waiting List-controlled Clinical Trial.
There is a current lack of sufficiently high-quality randomized controlled clinical trials that measure the effectiveness of neural tissue mobilization techniques such as median nerve neural mobilization (MNNM) and their specific effects on cervicobrachial pain (CP). The aim of this study was to compare the effectiveness of MNNM in subjects with CP vs. a waiting list control group (WLCG). ⋯ MNNM may be superior to no treatment in reducing pain and increasing function in the affected upper limbs of subjects with CP.

Corticosteroids are frequently used for the treatment of postoperative nausea and vomiting, and have also been reported to have an effect on postoperative analgesia. This study was conducted to assess the pain management effect of perioperative intravenous corticosteroids in patients undergoing total knee or hip arthroplasty and evaluate their early rehabilitation. ⋯ Our results show that intravenous corticosteroids have good efficacy and safety when used perioperatively in total knee or hip arthroplasty.

Randomized Controlled Trial
Influence of morphine and naloxone on pain modulation in Rheumatoid Arthritis, Chronic Fatigue Syndrome/Fibromyalgia and controls: a double blind randomized placebo-controlled cross-over study.
Impaired pain inhibitory and enhanced pain facilitatory mechanisms are repeatedly reported in patients with central sensitization pain. However, the exact effects of frequently prescribed opioids on central pain modulation are still unknown. ⋯ This study revealed anti-hyperalgesia effects of morphine in CFS/FM and RA patients. Nevertheless, these effects were comparable to placebo. Besides, neither morphine nor naloxone influenced deep tissue pain, temporal summation or CPM. Therefore, these results suggest that the opioid system is not dominant in (enhanced) bottom-up sensitization (temporal summation) or (impaired) endogenous pain inhibition (CPM) in patients with CFS/FM or RA.
