Review Meta Analysis
Anti-tumor necrosis factor antagonists in the treatment of low back pain and radiculopathy: a systematic review and meta-analysis.
Low back pain, with or without radiculopathy, is an important cause of disability and economic expenditure. However, many patients are not achieving optimal pain control with existing medications. Tumor necrosis factor antagonists (anti-TNFα) could be an alternative drug treatment. ⋯ There is low evidence that epidural etanercept has a low-to-moderate effect size when compared to placebo for pain due to discogenic lumbar radiculopathy (5 studies, n=185), with a standardized mean difference = -0.43 (95% confidence interval [CI] -0.84 to -0.02).There is moderate evidence that epidural etanercept does not have a higher adverse effects incidence rate when compared to placebo for discogenic lumbar radiculopathy (5 studies, n = 185) with a relative risk (RR) = 0.84 (95% CI 0.53 to 1.34).There is moderate evidence that anti-TNFα does not have a higher adverse effects incidence rate when compared to placebo for low back pain (10 studies, n= 343) with an RR = 0.93 (95% CI 0.56 to 1.55).We strongly suggest that anti-TNFα continue to be studied in experimental settings for the treatment of low back pain. We cannot currently recommend this therapy in clinical practice. New research could shed some light on the efficacy of anti-TNFα and change this recommendation in the future.

Multicenter Study
Craniofacial pain and disability inventory (CF-PDI): development and psychometric validation of a new questionnaire.
Orofacial pain, headaches, and neck pain are very common pain conditions in the general population and might be associated in their pathophysiology, although this is not yet clarified. The development and validation of a prediction inventory is important to minimize risks. Most recent questionnaires have not focused on pain, but pain is the common symptom in temporomandibular disorders, headaches, and neck pain. It is necessary to provide tools for these conditions. ⋯ The CF-PDI showed good psychometric properties. Based on the findings of this study, the CF-PDI can be used in research and clinical practice for the assessment of patients with craniofacial pain.

Randomized Controlled Trial
A randomized, double-blind, active-control trial of the effectiveness of lumbar interlaminar epidural injections in disc herniation.
Among the multiple nonsurgical modalities, epidural injections are one of the most commonly utilized treatment modalities in managing chronic low back and lower extremity pain due to disc herniation and radiculitis. There is a paucity of randomized trials from contemporary interventional pain management settings utilizing fluoroscopy with long-term follow-up. ⋯ Lumbar interlaminar epidural injections of local anesthetic with or without steroids is an effective modality, in patients with chronic function limiting low back and lower extremity pain secondary to disc herniation after failure of conservative modalities.

Randomized clinical trials assessing the efficacy and tolerability of tonabersat compared with placebo as prophylaxis for migraine were systematically reviewed in this study. By analyzing all available data, we aimed to establish an overall estimate of any association in order to more accurately inform clinicians and care-givers about how to prevent migraines. ⋯ There is fair evidence for migraine prophylaxis, but a lack of available evidence for tonabersat for migraine prophylaxis. Although tonabersat failed to demonstrate a significantly greater reduction of migraine headache days than placebo, it was well tolerated. Future work should further investigate the utility of tonabersat in the preventive management of migraine.

Despite hints about the high incidence of pain patients misreporting their pain medication use, there are only a few non-controlled studies on the topic that focus solely on opioids. ⋯ NCT01625065; Medi-3889-10.
