Bariatric surgery may provide an added benefit to severely obese patients besides weight loss: it can also help alleviate the excruciating pain of migraine headaches, according to new research. Researchers say obese patients who had suffered painful and debilitating migraines before bariatric surgery reported improvements in headache frequency, severity and disability just six months after surgery. At that point, most patients had lost an average of 66.4 pounds.

'Surgeon enthusiasm' helps explains regional variations in low back surgery
March 25, 2011 Source: Lippincott Williams & Wilkins
Surgeons in some areas are more likely to recommend surgery for low back problems and those differences in "surgeon enthusiasm" are a major factor driving regional variations in spinal surgery rates, suggests a new study. In contrast, variations in spinal surgery are unrelated to enthusiasm among patients and primary care doctors.

Acupuncture for pain no better than placebo -- and not without harm, study finds
March 23, 2011 Source: Elsevier Health Sciences
Although acupuncture is commonly used for pain control, doubts about its effectiveness and safety remain. Investigators critically evaluated systematic reviews of acupuncture as a treatment of pain in order to explore this question. They conclude that numerous systematic reviews have generated little truly convincing evidence that acupuncture is effective in reducing pain, and serious adverse effects continue to be reported.

Botox, is unlikely to offer much benefit in its most recently licensed use - as a treatment for chronic migraine - says a new Drug and Therapeutics Bulletin (DTB). DTB considers the published evidence on Botox's effectiveness as a treatment for chronic migraine limited and unconvincing. And, crucially, Botox leads to worsening of headache symptoms in around one in 10 people, with a similar proportion developing itching, rash, pain, stiffness and muscles spasms.

'Cross-talk' research may pave the way to understanding and controlling chronic pain
March 9, 2011 Source: University of California - Davis Health System
Researchers at the University of California, Davis have discovered a "cross-talk" between two major biological pathways that involve pain -- research that may pave the way to new approaches to understanding and controlling chronic pain. The newly published research reveals that analgesia mediated by inhibitors of the enzyme, soluble epoxide hydrolase (sEH), is dependent on a pain-mediating second messenger known as cyclic adenosinemonophosphate or cAMP.
