Review Meta Analysis
Summary measures of number needed to treat: how much clinical guidance do they provide in neuropathic pain?
Several systematic reviews of randomized controlled trials (RCTs) of drugs to treat neuropathic pain have reported summary estimates of efficacy - specifically, the number needed to treat (NNT). ⋯ Summary NNT estimates may have limited clinical relevance, due to problems of heterogeneity. The most that can be extracted from systematic reviews published to date is the identity of drugs that have demonstrated efficacy for specific types of neuropathic pain, and the strength of such evidence.

Review Meta AnalysisPhysical interventions and injection techniques for reducing injection pain during routine childhood immunizations: systematic review of randomized controlled trials and quasi-randomized controlled trials.
Vaccine injections are the most common reason for iatrogenic pain in childhood. With the steadily increasing number of recommended vaccinations, there has been a concomitant increase in concern regarding the adequacy of pain management. Physical interventions and injection techniques that minimize pain during vaccine injection offer an advantage over other techniques because they can be easily incorporated into clinical practice without added cost or time. Their effectiveness, however, has not previously been studied using a systematic approach. ⋯ Pain during immunization can be decreased by: (1) injecting the least painful formulation of a vaccine; (2) having the child sit up (or holding an infant); (3) stroking the skin or applying pressure close to the injection site before and during injection; (4) injecting the least painful vaccine first when 2 vaccines are being administered sequentially during a single office visit; and (5) performing a rapid intramuscular injection without aspiration.

Review Meta Analysis
Motor cortex stimulation for chronic pain: systematic review and meta-analysis of the literature.
To conduct a systematic review and meta-analysis to quantify the efficacy of invasive and noninvasive brain stimulation for the treatment of chronic pain. ⋯ This meta-analysis shows that two different techniques of brain stimulation of motor cortex--invasive and noninvasive--can exert a significant effect on pain in patients with chronic pain. We discuss potential reasons that invasive brain stimulation showed a larger effect in this meta-analysis. Our findings encourage continuation of research in this area and highlight the need for well-designed clinical trials to define the role of brain stimulation in pain management.

Meta Analysis Comparative StudyLidocaine 2% gel versus plain lubricating gel for pain reduction during flexible cystoscopy: a meta-analysis of prospective, randomized, controlled trials.
The current literature shows mixed results for the effectiveness of topical intraurethral lidocaine gel as local anesthesia during flexible cystoscopy. We performed a meta-analysis of randomized, controlled trials of the efficacy of 2% lidocaine vs plain gel for decreasing the pain that male patients incur during flexible cystoscopy. ⋯ Based on a meta-analysis of 9 randomized controlled trials there is no evidence to suggest a statistically significant difference in the efficacy of pain control between lidocaine gel and plain gel lubrication in men during flexible cystoscopy. This supports the conclusion that its benefit is limited to lubrication and any other perceived benefit is consistent with placebo.

Review Meta AnalysisPatellar taping and bracing for the treatment of chronic knee pain: a systematic review and meta-analysis.
To evaluate the evidence for patellar taping and bracing in the management of chronic knee pain. ⋯ There was evidence that tape applied to exert a medially-directed force on the patella produces a clinically meaningful change in chronic knee pain. There was limited evidence to demonstrate the efficacy of patellar bracing. These outcomes were limited by the presence of high heterogeneity between study outcomes and significant publication bias.
