Review Meta Analysis
Drug therapy for the treatment of chronic nonspecific low back pain: systematic review and meta-analysis.
Low back pain (LBP) is one of the most common health problems in adults. The impact of LBP on the individual can cause loss of health status in the form of symptoms and loss of function related to pain in the back; limitation of daily, leisure, and/or strenuous activities, and disability. LBP also poses an economic burden to society, mainly in terms of one of the most common reasons for seeking medical care (direct treatment costs), and accounts for the large number of work days lost (indirect costs). To reduce the impact of LBP on adults, drug therapy is the most frequently recommended intervention. Over the last decade, a substantial number of randomized clinical trials of drug therapy for LBP have been published. ⋯ This review endorses the use of COX-2 NSAIDs as the first-line drugs for CNLBP. Tramadol shows no statistically significant effect on pain relief, but has small effect sizes in improving functioning. Among included opioid therapy studies, the overall effects of opioids and the partial opioids agonist drug had statistically significant treatment effects in pain relief for CNLBP patients.

Review Meta Analysis
Prevalence of pain among nonmedical prescription opioid users in substance use treatment populations: systematic review and meta-analyses.
Prescription opioid analgesics (POA) are widely used in the pharmacotherapeutic treatment of acute and chronic pain in North America, where nonmedical prescription opioid use (NMPOU) has become a substantial public health concern in recent years. Existing epidemiological data suggest an association between NMPOU and pain problem symptoms in different populations, including samples in substance use treatment, although the extent of these correlations has not been systematically assessed. ⋯ Pain symptoms are disproportionately elevated in substance use treatment samples reporting NMPOU. Effective measures to prevent and treat NMPOU are urgently needed, although a substantive extent of NMPOU observed in this specific context may relate directly or indirectly to the presence of pain, e.g., either as an expression of ineffective pain care or as a consequence of previous POA-based interventions. At the same time, effective ways to treat and address ongoing pain issues in NMPOU samples need to be implemented, which may require ongoing opioid-based pharmacotherapeutic care aimed at both pain and dependence.

Meta Analysis Comparative Study
Comparative efficacy and safety of six antidepressants and anticonvulsants in painful diabetic neuropathy: a network meta-analysis.
Anticonvulsants and antidepressants are mostly used in management of painful diabetic neuropathy (PDN). However there are few direct comparisons between drugs of these classes, making evidence-based decision-making in the treatment of painful diabetic neuropathy difficult. ⋯ Gabapentin was found to be most efficacious and amitriptyline to be least safe among the treatments included in the study. Gabapentin showed most favorable balance between efficacy and safety.

The prevalence, costs, and disability associated with chronic pain continue to escalate. So too, the numerous modalities of treatments applied in managing these patients continue to increase as well. In the period from 2000 to 2011 interventional techniques increased 228%. ⋯ Apart from variability in the development of coverage policies, payments also substantially vary by site of service. In general, amongst the various ambulatory settings the highest payments are made to hospital outpatient departments (HOPDs) the lowest to in-office procedures, and payment to ambulatory surgery centers (ASCs) falling somewhere in the middle. This manuscript describes the many differences that exist between the various settings, and includes suggestions for accountable interventional pain management with coverage for techniques with evidence, addressing excessive use of specific techniques, and equalizing payments across multiple ambulatory settings.

Given that there are gender differences in pain perception, it is likely that there are differences in pain responses between men and women with lumbar spinal stenosis (LSS). Furthermore, these differences may lead to different degrees of impairment in both daily activities and quality of life between men and women. ⋯ Women showed increased low back pain and leg pain due to degenerative LSS compared to men. The current study demonstrates that this difference in symptom severity may be partly mediated by pain sensitivity.
