To investigate whether comorbid major depressive disorder (MDD) influenced the efficacy and safety of duloxetine in treating fibromyalgia (FM). ⋯ Duloxetine was effective in reducing pain and other symptoms in FM patients with and without MDD and demonstrated a similar safety profile for both groups.

Meta Analysis
Predictors of placebo response in pooled lamotrigine neuropathic pain clinical trials.
One limitation of neuropathic pain clinical trials is the often large and variable extent of response in the placebo group, possibly obscuring true medication effects. We pooled data from 252 individuals in the placebo arms of 3 clinical trials of lamotrigine in patients with neuropathic pain to examine the relationship of baseline patient and study site characteristics with 12-week change in the Pain Intensity Numerical Rating Scale score (DeltaPI-NRS). The 574 patients in the pooled lamotrigine treatment arms were used as a replication dataset. ⋯ These results suggest that both patient and study site characteristics can influence the response in the placebo arms of neuropathic pain studies.

To summarize the available evidence on the use of anticonvulsant drugs for the treatment of various conditions of neuropathic pain. ⋯ Gaps in the evidence are striking. Recommendations directly supported by the evidence by drug and by condition are made.

Randomized Controlled Trial Clinical Trial
Efficacy of microcurrent therapy in the treatment of chronic nonspecific back pain: a pilot study.
Microcurrent therapy (MCT) is a novel treatment for pain syndromes. The MCT patch is hypothesized to produce stimuli that promote tissue healing by facilitating physiologic currents. Solid evidence from randomized clinical trials is lacking. To evaluate the efficacy of MCT in treating aspecific, chronic low-back pain, we conducted a double-blind, randomized, crossover, pilot trial. ⋯ A positive trend in MCT use for aspecific, chronic low-back pain is reported. Further investigations are required to evaluate the significance and relevance of this.

Randomized Controlled Trial
A randomized controlled trial of vapocoolant for pediatric immunization distress relief.
The purpose of this study was to evaluate the effectiveness of vapocoolant for preschoolers' immunization injection pain relief. ⋯ This study revealed that vapocoolant is not an effective pain management intervention for children's intramuscular injections.
