Randomized Controlled Trial
Does intrathecal morphine sulfate provide preemptive analgesia for patients undergoing stapled hemorrhoidopexy?
Surgical excision of hemorrhoids is characterized by a prolonged and painful postoperative course. This double-blind, randomized, prospective, controlled trial was conducted to determine if morphine sulfate provides additional pain relief after stapled hemorrhoidopexy when added to a standard lidocaine spinal anesthetic. It was hypothesized that the addition of morphine sulfate to a spinal anesthetic would decrease postoperative pain. ⋯ This study provides evidence that intrathecal morphine sulfate does not significantly alter postoperative pain, narcotic use, or well-being when used as preemptive analgesia for patients undergoing stapled hemorrhoidopexy.

Randomized Controlled Trial
Physical activity within a CBT intervention improves coping with pain in traumatized refugees: results of a randomized controlled design.
Many traumatized refugees experience both posttraumatic stress disorder and chronic pain. Based on Mutual Maintenance Theory and the Perpetual Avoidance Model, this study examined the additional effect of physical activity within a biofeedback-based cognitive behavioral therapy (CBT-BF) for traumatized refugees. ⋯ Findings of improved coping strategies, larger effect sizes, and higher rates of clinical improvement in the CBT-BF+active group suggest that physical activity adds value to pain management interventions for traumatized refugees. Given the small sample size, however, these preliminary results need replication in a larger trial.

Randomized Controlled Trial Multicenter Study
A multicenter, randomized, double-blind, controlled study of NGX-4010, a high-concentration capsaicin patch, for the treatment of postherpetic neuralgia.
To confirm the efficacy, tolerability, and safety of NGX-4010, an 8% capsaicin dermal patch (capsaicin 640 µg/cm(2) ), in patients with postherpetic neuralgia (PHN). PHN is a chronic pain disorder that can be difficult to treat and for which current treatment options are often limited by poor tolerability. ⋯ In patients with PHN, a single 60-minute application of NGX-4010 produced significant reduction in pain that was maintained over a 12-week period.

Randomized Controlled Trial
Efficacy of diclofenac sodium in pain relief after conventional radiofrequency denervation for chronic facet joint pain: a double-blind randomized controlled trial.
Many patients experience pain for a short duration after conventional radiofrequency (CRF) denervation for lumbar facet pain. The aim of the present study was to evaluate the efficacy and cost of administering diclofenac sodium for the relief of pain after CRF denervation. ⋯ Diclofenac sodium administration improves analgesia and the PSS after CRF denervation. Compared to a 7-day dosage, a 3-day diclofenac sodium therapy has similar efficacy and less cost for the treatment of pain after CRF neurotomy.

Randomized Controlled Trial
Subcutaneous injection of botulinum toxin a is beneficial in postherpetic neuralgia.
To assess the benefits of subcutaneous injection of botulinum toxin A (BTX-A) for the treatment of postherpetic neuralgia (PHN). ⋯ Subcutaneous administration of BTX-A significantly decreased pain in PHN and reduced opioid use compared with lidocaine and placebo at day 7 and 3 months post-treatment. It also increased subjects' sleep times.
