ReviewOpioids for the Treatment of Chronic Pain: Mistakes Made, Lessons Learned, and Future Directions.
An overreliance on opioids has impacted all types of pain management, making it undoubtedly a root cause of the "epidemic" of prescription opioid abuse in the United States. Yet, an examination of the statistics that led the US Centers for Disease Control and Prevention to declare that prescription opioid abuse had reached epidemic levels shows that the abuse occurrences and deaths are arising outside the hospital or hospice setting, which strongly implicates the outpatient use of opioids to treat chronic pain. ⋯ Overprescribing to outpatients has afforded distressed and vulnerable individuals access to these highly addictive drugs. The focus of this article is on what we have learned since opioid treatment of chronic pain was first popularized at the end of the 20th century and how this new information can guide chronic pain management in the future.

Primary dysmenorrhea (PD), or painful menstruation in the absence of identified uterine pathology, affects 5 to 9 in every 10 reproductive-aged women. Despite its high prevalence, just a few studies with very small patient numbers have focused on health-related quality of life impairment in PD. We aimed to assess health-related quality of life values for a severe and a mild hypothetical PD health state using 10-year time trade-off and willingness-to-pay methods. ⋯ Compared with the non-PD group, women with PD valued both health states worse according to willingness to pay (P < 0.05) but similar in the time trade-off. It seems that PD substantially contributes to the quality-adjusted life year loss in this age group, which is comparable with losses from chronic diseases such as type 1 diabetes, asthma, atopic eczema, or chronic migraine. Our findings provide a useful input to cost-effectiveness and cost-benefit analyses of PD treatments.

A Contemporary Medicolegal Analysis of Outpatient Medication Management in Chronic Pain.
Opioids are frequently used in chronic pain management but are associated with significant morbidity and mortality in some patient populations. An important avenue for identifying complications-including serious or rare complications-is the study of closed malpractice claims. The present study is intended to complement the existing closed claims literature by drawing on claims from a more recent timeframe through a partnership with a large malpractice carrier, the Controlled Risk Insurance Company (CRICO). The goal of this study was to identify patient medical comorbidities and aberrant drug behaviors, as well as prescriber practices associated with patient injury and malpractice claims. Another objective was to identify claims most likely to result in payments and use this information to propose a strategy for reducing medicolegal risk. ⋯ Claims related to outpatient medication management in pain medicine are multifactorial, stemming from deficits in clinical judgment by physicians, noncooperation in care by patients, and poor clinical documentation. Minimization of both legal risk and patient harm can be achieved by carefully selecting patients for chronic opioid therapy and documenting compliance and improvement with the treatment plan. Medical comorbidities such as obstructive sleep apnea and the use of long-acting opioids may be particularly dangerous. Continuing physician education on the safest and most effective approaches to manage these medications in everyday practice will lead to both improved legal security and patient safety.

Significant age- and experience-dependent remodelling of spinal and supraspinal neural networks occur, resulting in altered pain responses in early life. In adults, endogenous opioid peptide and endocannabinoid (ECs) pain control systems exist which modify pain responses, but the role they play in acute responses to pain and postnatal neurodevelopment is unknown. Here, we have studied the changing role of the ECs in the brainstem nuclei essential for the control of nociception from birth to adulthood in both rats and humans. ⋯ The expression patterns and levels of ECs enzymes and receptors were assessed using quantitative PCR and immunohistochemistry. In human brainstem, we show age-related alterations in the expression of key enzymes and receptors involved in ECs function using PCR and in situ hybridisation. These data reveal that significant changes on ECs that to this point have been unknown and which shed new light into the complex neurochemical changes that permit normal, mature responses to pain.
