To explore the treatment patterns of patients with a diagnosis related to chronic pain (DRCP) initiating pharmacological treatment indicated for neuropathic pain (NeuP: tricyclic antidepressants, serotonin-norepinephrine reuptake inhibitors, and anticonvulsants). ⋯ Treatment initiation of currently available drugs indicated for neuropathic pain less frequently lead to long-term treatment in clinical practice compared with clinical trial, and few try more than one drug. We suggest our findings to be indications of a need for better routines in diagnosing patients to ascertain optimal treatment and follow-up.

Randomized Controlled Trial Multicenter Study
Experience and challenges presented by a multicenter crossover study of combination analgesic therapy for the treatment of painful HIV-associated polyneuropathies.
There is limited evidence for efficacy of analgesics as monotherapy for neuropathic pain associated with HIV-associated polyneuropathies, in spite of demonstrated efficacy in other neuropathic pain conditions. We evaluated the tolerability and analgesic efficacy of duloxetine, methadone, and the combination of duloxetine-methadone compared with placebo. ⋯ Challenges with participant recruitment and poor retention precluded trial completion to its planned targets, limiting our evaluation of the analgesic efficacy of the study treatments. Challenges to successful completion of this study and lessons learned are discussed.

The objective of this project was to develop core competencies in pain assessment and management for prelicensure health professional education. Such core pain competencies common to all prelicensure health professionals have not been previously reported. ⋯ These competencies can serve as a foundation for developing, defining, and revising curricula and as a resource for the creation of learning activities across health professions designed to advance care that effectively responds to pain.

Given the increase in misuse and abuse of prescription opioids, clinicians clearly benefit from a standardized tool to screen patients being considered for chronic opioid therapy. The Screener and Opioid Assessment for Patients with Pain-Revised (SOAPP-R) is a widely used opioid risk assessment tool in clinical practice. As one third of the US population experiences chronic noncancer pain at any given time, and the Hispanic population now accounts for about 16% of the nation's population, the availability of a Spanish-language SOAPP-R fills an important clinical need. ⋯ The Spanish SOAPP-R may be useful as a risk assessment tool, considered along with other clinical information, by clinicians who prescribe opioid therapy for patients whose preferred language is Spanish.

The present study was aimed at the issue of whether peripheral nerve injury-induced chronic pain is maintained by supraspinal structures governing descending facilitation to the spinal dorsal horn, or whether altered peripheral nociceptive mechanisms sustain central hyperexcitability and, in turn, neuropathic pain. We examined this question by determining the contribution of peripheral/spinal mechanisms, isolated from supraspinal influence(s), in cutaneous hypersensitivity in an animal model of peripheral neuropathy. ⋯ Our findings demonstrate an aberrant peripheral/spinal mechanism that induces and maintains thermal and to a greater degree tactile cutaneous hypersensitivity in the cuff model of neuropathic pain, and raise the prospect that altered peripheral/spinal nociceptive mechanisms in humans with peripheral neuropathy may have a pathologically relevant role in both inducing and sustaining neuropathic pain.
