Patients who suffer from migraines often report impaired quality of life. Occipital nerve stimulation (ONS) is a novel treatment modality for migraines, although few systematic reviews have evaluated whether this therapy is efficacious. The objective of this study was to evaluate the clinical efficacy and safety of ONS for treating migraine through a literature review. ⋯ Improvement in the migraine disability assessment (MIDAS) score was more dramatic than improvement in the SF-36 score at follow-up. The mean complication incidence of ONS was 66% for the reviewed studies. Future clinical studies should optimize and standardize the ONS intervention process and identify the relationship among the surgical process, efficacy, and complications resulting from the procedure.

A range of outcome measures across various domains are used to evaluate change following an intervention in clinical trials on chronic neuropathic pain (NeP). However, to capture a real change in the variable of interest, the psychometric properties of a particular measure should demonstrate appropriate methodological quality. Various outcome measures in the domains of pain and physical functioning have been used in the literature for NeP, for which individual properties (eg, reliability/validity) have been reported. To date, there is no definitive synthesis of evidence on the psychometric properties of those outcome measures; thus, the aim of this systematic review was to evaluate the methodological quality [COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) guidelines] of studies that evaluated psychometric properties of pain and physical functioning outcome measures used for NeP. ⋯ Although a variety of pain and physical functioning outcome measures have been reported in the literature, few have demonstrate methodologically strong psychometric properties. Thus, future research is required to further investigate the psychometric properties of existing pain and physical functioning outcome measures used for clinical and research purposes.

Chronic pain is more prevalent in indigenous populations who often prefer traditional remedies over allopathic drugs. Our objective was to investigate the traditional uses of medicinal plants from the Canadian boreal forest for the management of chronic pain syndromes. ⋯ Our study showed the potential of boreal plants as alternative and complementary medicines for the treatment of chronic pain syndromes that could be enhanced by further research on efficacy and safety issues.

Chronic pain (CP) patients with depression typically exhibit worse post-treatment outcomes than nondepressed CP patients. The cause is often assumed to reflect a differential response to treatment, neglecting other potential explanations, such as the continuation of differences in pretreatment outcomes. This post hoc analysis examines whether worse post-treatment outcomes for depressed patients with chronic low back pain (CLBP) are driven by reduced treatment efficacy. ⋯ Results do not support a differential response to BTDS treatment between depressed and nondepressed CLBP patients across a variety of patient-reported outcomes. These findings raise the question of whether depressed mood actually moderates the effectiveness of treatment in CP patients.

Randomized Controlled Trial
Safety and Efficacy Study of the Cyclooxygenase-2 Inhibitor Parecoxib Sodium Applied for Postoperative Analgesia After Endo-Nasal Operation.
To evaluate the safety and efficacy of the cyclooxygenase-2 inhibitor parecoxib sodium after endo-nasal operation. ⋯ Parecoxib sodium was effective and safe when used for postoperative analgesia in endo-nasal operation.
