Current opinion in supportive and palliative care

Conditioned pain modulation (CPM) paradigms have been increasingly used over the past few years to assess endogenous analgesia capacity in healthy individuals and pain patients. The current review concentrates on selected recent literature advancing our understanding and practice of CPM. ⋯ The reviewed literature refines the methodology used for eliciting CPM responses and characterizing their physiological attributes in healthy individuals and pain patients, and exemplifies the materializing concept of individualized pain medicine through targeting impaired mechanisms of pain modulation by designated drugs for optimal pain alleviation.

ReviewCould targeting epigenetic processes relieve chronic pain states?
Aberrations in the epigenetic landscape have previously been associated with human diseases such as cancer and schizophrenia, and drugs that target epigenetic processes are currently used as therapeutic agents. This article will review the evidence obtained from animal studies indicating that epigenetic processes might regulate long-term pain states and then discuss the possibility that targeting epigenetic mechanisms might be useful for the management of chronic pain. ⋯ The field of epigenetics and pain is rapidly emerging but further investigation is needed to fully comprehend the contribution of epigenetic processes to chronic pain states. Although therapeutic approaches targeting these mechanisms might seem worthwhile, we cannot assert that currently available global tools such as histone deacetylase inhibitors can be used successfully for the long-term treatment of chronic pain states.
