Video from 2011 NIH Pain Consortium Symposium are now online and this year it was entitled "Mechanisms and Management of Overlapping Chronic Pain and Associated Conditions." There were many interesting presentations about chronic pain and I highly recommend it. Here, I'll briefly mention presentation by Dr. Michael J. Iadarola about New Approaches to Analgesia Involving TRPV1 Agonists and Allosteric Modulators. It provides excellent background information about ongoing clinical trial for Resiniferatoxin to Treat Severe Pain Associated With Advanced Cancer. Resiniferatoxin (RTX) is a natural product extracted from cactus-like plants that grow in some parts of Africa. You can learn more about this clinical trial by watching this video (5:27:29).
