PHILADELPHIA – Experts from the University of Pennsylvania School of Medicine are available to offer expert medical insight and commentary during the 2010 Winter Olympics in Vancouver on issues ranging from the effects of performance enhancing drugs to concerns about the spread of novel H1N1, head trauma and more.

Pennsylvania Hospital primary care physician and Philadelphia Flyers team internist, Gary Dorshimer, MD, will travel to Vancouver to as an internal medicine consultant, treating NHL players playing for their respective national teams. He served in this same role at the 2002 Winter Olympics in Salt Lake City and at the 1998 Winter Olympics in Nagano.  

Highlighted experts include:

  • Head Trauma and Concussion
    • Douglas Smith, MD, professor of Neurosurgery and director of the Penn Center for Brain Injury and Repair is available to address risk factors for and medical problems resulting from traumatic brain injury. His laboratory’s research interests include investigating the biomechanical effects of traumatic brain injury, imaging techniques to diagnose injury, and the link between diffuse axonal injury and Alzheimer's disease.

  • Preventing the Spread of H1N1
    • Neil Fishman, MD, associate professor of Infectious Diseases; director of Healthcare Epidemiology, Infection Prevention & Control; president elect, Society for Healthcare Epidemiology of America, has been working vigorously with Penn Medicine and city of Philadelphia officials to prevent unnecessary spread of H1N1.  

      Fishman has been a leader in the planning and distribution of the H1N1 vaccine, transmission of the virus, symptoms, management, prevention strategies, high-risk populations, and the go-to expert in the Philadelphia region.

      He is available to discuss concerns about H1N1 before and during the Olympics, prevention strategies for athletes and spectators alike, as well as any concerns or related illnesses as they arise during the Olympics.  

    • Michael Buckley, MD, chair, Department of Medicine & chief medical officer, Pennsylvania Hospital is also available for comment on H1N1 and seasonal flu treatment and prevention as well as additional concerns around infectious diseases, including HIV.

  • Detecting The Next Generation Of Performance Enhancers
    • Tejvir S. Khurana, MD, PhD, associate professor of Physiology and a member of Penn's Pennsylvania Muscle Institute, is available to discuss new efforts to develop a test to detect performance enhancers that increase the blood's ability to carry oxygen, resulting in improved
      athletic performance.

      Dr. Tejvir S. Khurana is investigating ways to detect molecular signatures in blood and muscles to combat doping in sports, funded in part by the World Anti-Doping Agency (WADA).

      New performance-enhancing drugs aim to artificially increase the concentration of red blood cells in the body so more oxygen is delivered to muscles than normal, which can significantly improve an athlete's endurance and performance.

      Khurana and colleagues are studying how a mammal's physiology changes and what naturally triggers an increased red blood cell production at high altitudes.

Additional Penn Medicine Experts Available for Comment
