Meta Analysis
All-Cause and Overdose Mortality Risk Among People Prescribed Opioids: A Systematic Review and Meta-analysis.
To estimate all-cause and overdose crude mortality rates and standardized mortality ratios among people prescribed opioids for chronic noncancer pain and risk of overdose death in this population relative to people with similar clinical profiles but not prescribed opioids. ⋯ Methodological limitations in the identified literature complicate efforts to determine the overdose mortality risk of people prescribed opioids. There is a need for large-scale clinical trials to assess adverse outcomes in opioid prescribing, especially for chronic noncancer pain.

Randomized Controlled Trial
Thoracic Paravertebral Blockade Reduces Chronic Postsurgical Pain in Breast Cancer Patients: A Randomized Controlled Trial.
To evaluate the effect of multilevel single-shot thoracic paravertebral blockade (PVB) on the occurrence of chronic postsurgical pain (CPSP) in patients undergoing breast cancer surgery. ⋯ For patients undergoing breast cancer surgery, multilevel single-shot PVB reduces the incidence of CPSP at six months; it also improves early postoperative analgesia and reduces neuropathic pain at six and 12 months after surgery.

Randomized Controlled Trial
The Effect of Transcranial Direct Current Stimulation on Chronic Neuropathic Pain in Patients with Multiple Sclerosis: Randomized Controlled Trial.
Chronic neuropathic pain is a common symptom in multiple sclerosis (MS). This randomized controlled single-blinded study investigated whether a new protocol involving five days of transcranial direct current stimulation (tDCS) with an interval period would be effective to reduce pain using the visual analog scale (VAS). Other secondary outcomes included the Neuropathic Pain Scale (NPS), Depression Anxiety Stress Score (DASS), Short Form McGill Pain Questionnaire (SFMPQ), and Multiple Sclerosis Quality of Life 54 (MSQOL54). ⋯ This study shows that repeated stimulation with a-tDCS for five days can reduce pain intensity for a prolonged period in patients with MS who have chronic neuropathic pain.
