Multiple Sclerosis: Tracking Down The Causes
Over 100,000 people suffer from multiple sclerosis in Germany alone. Despite intensive research, the factors that trigger the disease and influence its progress remain unclear. Scientists from the Max Planck Institute of Neurobiology in Martinsried and an international research team have succeeded in attaining three important new insights into the disease. It would appear that B cells play an unexpected role in the spontaneous development of multiple sclerosis and that particularly aggressive T cells are activated by different proteins. Furthermore, a new animal model is helping the scientists to understand the emergence of the most common form of the disease in Germany.

Study Finds Survival Rates From Gastrointestinal Tumors Improving Among African-Americans
New research published in the July issue of the Journal of the American College of Surgeons reveals that African Americans with gastrointestinal stromal tumors (GIST), a rare cancer that begins in the wall of the gastrointestinal tract, now have survival rates equivalent to those of Caucasians. Prior to 2000, African Americans were more likely to develop GIST and less likely to undergo surgical treatment for this type of cancer.

Rush University Medical Center Performs First Colorectal Surgeries In The U.S. Using Prosurgics' FreeHand Laparoscopic Camera Controller

Rush University Medical Center and surgical robotics company Prosurgics announce the completion of the first colorectal surgeries in the U.S. using the FreeHand® laparoscopic camera controller. Surgeons Dr. Marc Brand and Dr. Theodore Saclarides of Rush University Medical Center in Chicago successfully completed three laparoscopic hemi-colectomies using the laparoscopic camera controller. Although FreeHand is used widely in Europe, and has application in a variety of surgical specialties, these were the first procedures of this type to be performed in the U.S. Dr. Brand operated the FreeHand system during the procedures, which took place on June 22. FreeHand is an affordable 15 lb. robotic device that gives surgeons direct control of the laparoscopic camera via a small, lightweight hands-free controller worn on the surgeon"s head. Gentle head movements permit precise scope positioning. It provides a rock-steady image and faster surgery after a very rapid learning curve. After using FreeHand, Dr. Brand said, "A laparoscopic colectomy is uniquely challenging in that a wide field of view is required, from the ribs to the pelvis. FreeHand provided visual coverage of the entire area. It also gave me control so that I did not have to interrupt dissection to reposition the camera, or tell a person holding the camera what to do; returning control of the camera view to the surgeon allows for the image to lead the procedure instead of follow it. It"s like having an extra pair of hands. The image was excellent and very steady and no one had to be in the O.R. just to hold the "scope." Bill Perry, President of Prosurgics Inc., said, "We are delighted to have done these advanced cases at this outstanding medical center and that FreeHand performed so well. FreeHand makes procedures quicker and less stressful, and is a great teaching tool as well. A growing number of leading centers across the U.S. are seeing the benefits of FreeHand in a variety of surgical specialties."
