Limited, low-dose infusions of a widely used anesthetic drug may relieve the often intolerable and debilitating pain of Complex Regional Pain Syndrome (CRPS), a Penn State Milton S. Hershey Medical Center researcher found.
"This pain disorder is very difficult to treat. Currently-available therapies, at best, oftentimes only make the pain bearable for many CRPS sufferers," said Ronald E. Harbut, M.D., Ph.D., assistant professor of anesthesiology, Penn State Hershey Medical Center. "In our retrospective study, some patients who underwent a low-dose infusion of ketamine experienced complete relief from their pain, suggesting that this therapy may be an option for some patients with intolerable CRPS."
The study, titled "Subanesthetic Ketamine Infusion Therapy: A Retrospective Analysis of a Novel Therapeutic Approach to Complex Regional Pain Syndrome," was published in the September 2004 issue of Pain Medicine, the official journal of the American Academy of Pain Medicine.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
