Drugs activating the mu opioid receptor are routinely used to treat severe acute and chronic pain. Unfortunately, side effects including nausea, constipation, respiratory depression, addiction and tolerance can limit clinical utility. In contrast, kappa opioid receptor (KOPr) agonists, such as Salvinorin A (SalA), have analgesic properties with little potential for abuse. ⋯ Salvinorin A and the novel analogue β-THP Salvinorin B show analgesic effects in the tail-withdrawal and formalin assays. They reduce oedema and decrease neutrophil infiltration into inflamed tissue, and suppress mechanical and cold allodynia in paclitaxel-induced neuropathic pain.

Randomized Controlled Trial
Cyclization of Motor Cortex Stimulation for Neuropathic Pain: A Prospective, Randomized, Blinded Trial.
Programming guidelines for motor cortex stimulation (MCS) in neuropathic pain requires further investigation. After optimizing voltage as a percentage of motor threshold, we evaluated the effect of cyclizing time of stimulation on pain relief for chronic neuropathic pain. ⋯ In this small cohort, cyclization of MCS settings revealed two distinct subgroups: responders and nonresponders. Responders tolerated stimulation in all settings and 50% stimulation (15 min ON/15 min off) was their subjectively preferred setting. Cyclization in responders will prolong battery life and delay the need for INS replacement and may offer improved pain relief. Building from our previous work, we recommend clinicians consider following the Vancouver MCS programming algorithm presented in this manuscript.

Patients with thoracic neuropathic pain often do not respond to medication and physical therapy. Coblation technology has been demonstrated to have potential for pain management. ⋯ Percutaneous thoracic paravertebral nerve coblation guided by computed tomography is a potential method for the treatment of thoracic neuropathic pain.

In a 5-year follow-up study in a hospital in southern China, it was shown that intervertebral foramen (IVF) injection of ozone at the involved segmental levels could significantly alleviate paroxysmal spontaneous pain and mechanical allodynia in patients with chronic, intractable postherpetic neuralgia (PHN) and improve the quality of life. However, so far no proof-of-concept studies in animals have been available. ⋯ Chronic pain, neuropathic pain, inflammatory pain, ozone therapy, interventional therapy, gabapentin, spared nerve injury, bee venom, complete Freud's adjuvant.
