Because of disparate taxonomic arrays for classification, the American Academy of Pain Medicine has proposed categorizing pain on a neurobiologic basis as eudynia (nociceptive pain), Greek for "good pain," or maldynia (maladaptive pain), Greek for "bad pain." The latter has been viewed as maladaptive because it may occur in the absence of ongoing noxious stimuli and does not promote healing and repair. ⋯ As defined, maldynia is a multidimensional process that may warrant consideration as a chronic disease not only affecting sensory and emotional processing but also producing an altered brain state based on both functional imaging and macroscopic measurements. However, the absolute clinical value of this definition is not established.

We herein provide a description of a health information technology tool using computer-assisted survey instruments as a methodology for documentation during long-term opioid therapy. ⋯ The PODS fulfills medicolegal requirements for documentation and provides a systematic means of determining outcomes. This process facilitates the determination of the appropriate intervals between clinic visits by stratifying patients into high, moderate, and low risk.

Pain is the most commonly reported symptom in primary care and is a leading cause of disability. Primary care providers (PCPs) face numerous challenges in caring for patients with chronic pain including communication and relational difficulties. ⋯ The clinical implications of these findings are two-fold. First, PCPs' needs cannot be ignored when considering pain care. PCPs need support, both instrumental and emotional, as they care for patients with chronic pain. Second, improving PCPs' patient-centered communication skills-including demonstrating empathy and encouraging shared decision-making-holds promise for alleviating some of the strain and burden reported by providers, ultimately leading to improved patient care.

The N-methyl-D-Aspartate (NMDA) receptor has been proposed as a primary target for the treatment of neuropathic pain. The aim of the present study was to perform a meta-analysis evaluating the effects of (individual) NMDA receptor antagonists on neuropathic pain, and the response (sensitivity) of individual neuropathic pain disorders to NMDA receptor antagonist therapy. ⋯ Based on this systematic review, no conclusions can yet be made about the efficacy of NMDA receptor antagonists on neuropathic pain. Additional RCTs in homogenous groups of pain patients are needed to explore the therapeutic potential of NMDA receptor antagonists in neuropathic pain.

Randomized Controlled Trial
Comparison of the effectiveness of lumbar transforaminal epidural injection with particulate and nonparticulate corticosteroids in lumbar radiating pain.
Lumbar transforaminal epidural steroid injections are procedures often utilized in the treatment of low back pain associated with radicular pain. Particulate steroids have been known to play a role in embolism. It is, unknown whether nonparticulate steroids are as effective as particulate steroids. To investigate the effect of an epidural steroid injection on back pain, we conducted a randomized, controlled trial comparing nonparticulate steroid with particulate steroid to treat lumbar disc herniation. ⋯ In this study, dexamethasone and triamcinolone treatments were shown to have different effects on low back pain with sciatica, with triamcinolone being more effective than dexamethsone in lumbar radiculopathy.
