Patients with chronic pain have been shown to be more frequent utilizers of primary care, a contributor to increased health care costs. This study aimed to clarify which patient factors predict primary care utilization among veterans with chronic pain. ⋯ Mental health conditions that commonly co-occur with chronic musculoskeletal pain contribute to greater health care utilization. Improved screening and early intervention for these disorders in primary care may improve patient outcomes and stem high rates of care utilization of veterans.

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.

Migraine is a common type of headache accompanied or preceded by signs of central and autonomic nervous system dysfunction. Autonomic dysfunction has been suggested to be a potential contributor to impaired cardiac diastolic function. Cardiac diastolic dysfunction is characterized by normal left ventricular contractility but impaired ventricular relaxation. It is a growing clinical entity implicated in morbidity and mortality due to heart failure. The aim of this study was to determine if any relationship exists between migraine and diastolic dysfunction. ⋯ Cardiac diastolic dysfunction is associated with migraine. A long history of migraine is an independent predictor of diastolic dysfunction.

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.
