Pain medicine agreements are frequently recommended for use with high-risk patients on chronic opioid therapy. We assessed how consistently pain medicine agreements were used and whether patients were aware that they had signed a pain medicine agreement in a sample of HIV-infected adults prescribed chronic opioid treatment. ⋯ In a high-risk sample, clinicians were using agreements at a low rate, but were more likely to use them with patients at highest risk of misuse. Patients exhibited low awareness of whether they signed a pain medicine agreement.

Pulsed radiofrequency (PRF) procedure has been used in clinical practice for the treatment of chronic neuropathic pain conditions without neuronal damage. The purpose of this study was to investigate the changes in pain response and glial expression after the application of PRF on a dorsal root ganglion (DRG) in a neuropathic pain model. ⋯ Our result demonstrated that the mechanical hypersensitivity, induced by L5 SNL, was attenuated by a PRF procedure on the ipsilateral DRG. This analgesic effect may be associated with an attenuation of the microglial activation in the dorsal horn.
