Migraine is associated with substantial functional impairment and affects many aspects of daily life.
Complex regional pain syndrome type-I (CRPS-I) is a progressive and devastating pain condition. The mechanisms of CRPS-I still remain poorly understood. We aim to explore expression profiles of genes relevant to pain and neuroinflammation mechanisms involved in CRPS-I.
Unilateral injection of Complete Freund's Adjuvant (CFA) into the intra-plantar surface of the rodent hindpaw elicits chronic inflammation and hyperalgesia in the ipsilateral hindlimb. Mechanisms contributing to this hyperalgesia may act over multiple time courses and can include changes in ion channel expression and post-translational SUMOylation. Hyperpolarization-activated, cyclic nucleotide-gated (HCN) channels mediate the hyperpolarization-activated current, I . An HCN2-mediated increase in C-nociceptor I contributes to mechanical hyperalgesia in the CFA model of inflammatory pain. Changes in HCN2 post-translational SUMOylation and protein expression have not been systematically documented for a given DRG throughout the time course of inflammation.
Exposure-response (E-R) models were developed to provide a description of the time-course of treatment effect for monthly and quarterly dosing regimens of fremanezumab.
Precise cannabis treatment dosing remains a major challenge, leading to physicians' reluctance to prescribe medical cannabis.
Mounting evidence indicates that disruptions in bidirectional communication pathways between the central nervous system (CNS) and peripheral immune system underlie the etiology of pathologic pain conditions. The purpose of this review is to focus on the cross-talk between these two systems in mediating nociceptive circuitry under various conditions, including nervous system disorders. Elevated and prolonged proinflammatory signaling in the CNS is argued to play a role in psychiatric illnesses and chronic pain states. Here we review current research on the dynamic interplay between altered nociceptive mechanisms, both peripheral and central, and physiological and behavioral changes associated with CNS disorders.
In response to the opioid epidemic, the Centers for Disease Control and Prevention issued guidelines (CDCG) in 2016 for the prescription of opioids for chronic pain. To facilitate research into whether CDCG implementation will lead to reductions in opioid prescribing and improved patient safety, we sought to validate a tool that quantifies CDCG adherence based on clinical documentation.
