Conditioned pain modulation (CPM) and offset analgesia (OA) are considered to represent paradigms of descending inhibitory pain modulation in humans. This study tested the effects of hydromorphone therapy on descending inhibitory pain modulation, as measured by changes from baseline in the magnitudes of CPM and OA. ⋯ These results suggest that the descending inhibitory pain modulation, as manifested in humans by CPM and OA, is unlikely to be mediated by hydromorphone therapy.

Randomized Controlled Trial
Nabilone as an adjunctive to gabapentin for multiple sclerosis-induced neuropathic pain: a randomized controlled trial.
Neuropathic pain (NPP) is a chronic syndrome suffered by patients with multiple sclerosis (MS), for which there is no cure. Underlying cellular mechanisms involved in its pathogenesis are multifaceted, presenting significant challenges in its management. ⋯ Nabilone as an adjunctive to GBP is an effective, well-tolerated combination for MS-induced NPP. The results of this study identify a novel therapeutic combination for use in this population of patients predisposed to tolerability issues that may otherwise prevent effective pain management.

Randomized Controlled Trial
Cervical transforaminal epidural block using low-dose local anesthetic: a prospective, randomized, double-blind study.
Intra-arterial injections of local anesthetic during cervical transforaminal epidural block (TFEB) can cause rare but fatal neurologic complications. We hypothesized that using a dose of local anesthetic lower than seizure threshold during cervical TFEB would not be associated with seizure activity in cases of accidental intra-arterial injection. ⋯ Cervical TFEB performed using 0.125% lidocaine with dexamethasone achieved similar satisfactory effects as 1% lidocaine with dexamethasone for the treatment of cervical radicular pain. Therefore, the use of low-dose lidocaine with dexamethasone is reasonable for cervical TFEB, as this may reduce the incidence of rare but fatal complications.

Clinical Trial
A brief peer support intervention for veterans with chronic musculoskeletal pain: a pilot study of feasibility and effectiveness.
The aim of this study was to pilot test a peer support intervention, involving peer delivery of pain self-management strategies, for veterans with chronic musculoskeletal pain. ⋯ This study suggests that peers can effectively deliver pain self-management strategies to other veterans with pain. Although this was a pilot study with a relatively short intervention period, patients improved on several outcomes.
