Randomized Controlled Trial
Report of a Preliminary Discontinued Double-Blind, Randomized, Placebo-Controlled Trial of the Anti-TNF-α Chimeric Monoclonal Antibody Infliximab in Complex Regional Pain Syndrome.
Inflammation appears to play a role in CRPS as, for example, cytokines (like TNF-α) are involved in the affected limb. The ongoing inflammation is probably responsible for the central sensitization that sometimes occurs in CRPS. Thus, early start of a TNF-α antagonist may counteract inflammation, thereby preventing rest damage and leading to recovery of the disease. ⋯ This study was terminated before the required number of participants had been reached for sufficient statistical power. Nevertheless, a trend was found toward an effect of infliximab on the initially high TNF-α concentration.

Randomized Controlled Trial
The role of fluoroscopic interlaminar epidural injections in managing chronic pain of lumbar disc herniation or radiculitis: a randomized, double-blind trial.
There is continued debate on the effectiveness, indications, and medical necessity of epidural injections in managing pain and disability from lumbar disc herniation, despite extensive utilization. There is paucity of literature on interlaminar epidural injections in managing lumbar disc herniation or radiculitis in contemporary interventional pain management settings utilizing fluoroscopy. ⋯ Lumbar interlaminar epidural injections of local anesthetic with or without steroids might be effective in patients with disc herniation or radiculitis, with potential superiority of steroids compared with local anesthetic alone at 1 year follow-up.

Randomized Controlled Trial
Randomized controlled trial on the efficacy of bilateral superficial cervical plexus block in thyroidectomy.
As thyroid surgery is being performed as an ambulatory procedure, recent studies concerning post thyroidectomy analgesia have focused on regional techniques such as bilateral superficial cervical plexus block (BSCPB) and bilateral combined superficial and deep cervical plexus block. But, data regarding the efficacy of BSCPB are controversial. Hence we compared the efficacy of BSCPB with 0.25% bupivacaine with and without clonidine in thyroidectomy, as preventative analgesia. ⋯ BSCPB with 0.25% bupivacaine with or without clonidine is effective in reducing both intraoperative and postoperative pain and analgesic requirements in thyroidectomy, and adding clonidine to bupivacaine reduces postoperative vomiting.

Randomized Controlled Trial Multicenter Study
A randomized, controlled trial of gabapentin enacarbil in subjects with neuropathic pain associated with diabetic peripheral neuropathy.
Gabapentin enacarbil (GEn), a transported prodrug of gabapentin, provides sustained, dose-proportional gabapentin exposure. The purpose of this study was to investigate the dose response of GEn to select the optimal dose(s) for clinical use in subsequent diabetic peripheral neuropathy (DPN) trials. ⋯ Overall, none of the GEn treatment groups differentiated from placebo. Analyses of the secondary endpoints showed comparable results across treatment groups. However, the majority of the endpoints, including all of the pain endpoints, showed the largest numerical treatment difference was between GEn 3,600 mg and placebo. The active control, PGB (300 mg/day), did not differentiate from placebo.

Randomized Controlled Trial
0.025% capsaicin gel for the treatment of painful diabetic neuropathy: a randomized, double-blind, crossover, placebo-controlled trial.
Topical therapy may provide additional benefit in patients with painful diabetic neuropathy (PDN). This study was conducted to study the safety and efficacy of 0.025% capsaicin gel in this condition. ⋯ 0.025% capsaicin gel is safe and well tolerated, but does not provide significant pain relief in patients with PDN.
