Prescription opioid misuse is a serious public health concern, yet antecedent factors are poorly described. Using data from the National Longitudinal Study of Adolescent to Adult Health (N = 14,784), we examined the longitudinal relationship between a history of adolescent chronic pain and the odds of misusing prescription opioids in adulthood. The primary predictor variable was chronic pain status during adolescence. ⋯ Longitudinal associations between adolescent chronic pain and subsequent adult prescription opioid misuse highlight the need for early targeted screening and prevention efforts that may reduce later opioid misuse. Perspective: Using a large, nationally representative sample, we found that chronic pain during adolescence was an independent risk factor for opioid misuse in adulthood, over and above other known risk factors. Furthermore, among those individuals with adolescent chronic pain, substance use, exposure to trauma, and race were associated with opioid misuse.

Randomized Controlled Trial
Cost-effectiveness and cost-utility of internet-delivered exposure therapy for fibromyalgia: results from a randomized controlled trial.
Fibromyalgia (FM) is a prevalent and debilitating chronic pain disorder associated with a substantial economic burden. Although there are several studies investigating the effectiveness of psychological treatments such as cognitive-behavioral therapy for FM, studies on cost-effectiveness are scarce. The aim of the present study was to investigate the cost-effectiveness of Internet-delivered exposure therapy (iExp) for FM. ⋯ PERSPECTIVE: Health-economic evaluations of psychological interventions for FM are scarce. This study is a cost-effectiveness analysis of Internet-delivered exposure therapy for patients with FM. Results showed that iExp was highly cost-effective compared with no treatment, where each successfully treated case generated a substantial societal cost saving.

Our aim was to investigate the differences in pressure sensitivity over musculoskeletal and nerve symptomatic and distant areas between individuals with plantar heel pain and healthy subjects and to determine the relationship between sensitivity to pressure pain, foot pain, and fascia thickness. Thirty-five patients with unilateral chronic plantar heel pain and 35 matched healthy controls participated. Pressure pain thresholds (PPTs) were assessed bilaterally over several nerve trunks (median, radial, ulnar, common peroneal, tibial, and sural nerve trunks) and musculoskeletal structures (calcaneus, medial gastrocnemius, tibialis anterior, and second metacarpal) by an assessor blinded to the subject's condition. ⋯ This study found widespread pressure pain hypersensitivity over both nerve trunks and musculoskeletal structures in individuals with unilateral chronic plantar heel pain, suggesting the presence of a central altered central nociceptive pain processing. Pressure hypersensitivity over nerve trunks on the lower extremity was associated with higher pain intensity and related disability. PERSPECTIVES: This study found widespread pressure hypersensitivity over both nerve trunks and musculoskeletal structures in individuals with unilateral chronic plantar heel pain, as a manifestation of a centrally altered central nociceptive pain processing.

Review Meta Analysis
Combination Drug Therapy for the Management of Low Back Pain and Sciatica: Systematic Review and Meta-Analysis.
Combining medicines may give greater pain relief and/or improved tolerability. We conducted a systematic review to investigate the effects of combination drug therapy in patients with low back pain and/or sciatica on pain, disability, and adverse events. Databases and trial registers were searched from inception to July 27, 2017, for randomized trials of (sub)acute or chronic back pain or sciatica participants that were administered combination drug therapy compared with monotherapy or placebo. ⋯ There is no clear evidence to support any combination drug therapy for the management of low back pain and sciatica due to the limited number of studies and overall low quality of evidence. Perspective: Combining medicines may give greater pain relief and/or improved tolerability compared with single-ingredient medicines. However, the lack of studies and overall low quality of evidence limit the recommendation of combination drug therapy for the management of low back pain and sciatica.

We assessed the effects of opioid dose and risk reduction initiatives on opioid overdose rates among patients on chronic opioid therapy (COT). Using an interrupted time series design, we compared trends in overdose rates. We compared patients on COT in settings that implemented a COT dose reduction initiative and then a COT risk stratification/monitoring initiative to similar patients on COT from control settings. ⋯ PERSPECTIVE: Risk stratification/monitoring interventions among patients on COT did not decrease opioid overdose rates. The effects of COT dose reduction on opioid overdose rates were inconsistent. Greater decreases in COT dose, a larger control group, or both may have been needed to identify conclusive reductions in opioid overdose rates.
