CT colonography not presently a viable option for colorectal cancer screening

Findings of a new multicenter study by Cotton et al. published today in the Journal of the American Medical Association comparing standard colonoscopy with CT colonography for the detection of colorectal cancer reveal that this technology, in the form used most often in the United States, while of significant interest, is not presently a viable option for routine colorectal cancer screening.

Differing views on virtual colonoscopy accuracy

Demonstrating clearly that not all virtual colonoscopies are equal, the study, published in the December 2003 issue of The New England Journal of Medicine and the American Journal of Roentgenology, found the results found using the Viatronix V3D-Colon system for primary 3D reading to be equal to or better than optical colonoscopy results.

Researchers examine community-based drinkers rather than abstinent alcoholics

Almost all knowledge about brain damage due to chronic alcohol consumption has been gathered from alcoholics, who have generally been studied toward the end of their institutionalized treatment program (several weeks after their last drink) or many months into abstinence.

CT colonography lacks the sensitivity of conventional colonoscopy

A new study published in JAMA on CT colonography or 'virtual' colonoscopy using 2-D imaging finds that this test lacks the sensitivity and specificity of conventional colonoscopy for colorectal cancer screening. Study co-author and American College of Gastroenterology President Douglas K. Rex, M.D. is available for interviews.

VCU Medical Center goes high definition

The startlingly clear images displayed by high definition televisions have attracted the attention of sports enthusiasts, movie fanatics, and video gamers. Now some surgeons at the Virginia Commonwealth University Medical Center are among the first in the country to use the technology to gain extraordinary views of the human anatomy.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.

Time-reversal acoustics research promises medical breakthroughs

Scientists have not yet found a way to actually make time run backward, but in the cutting-edge world of recent acoustics research, they have shown a way to make sound waves run backward in a kind of ultra-focused reverse echo. By the technology known as time-reversal acoustics, sound waves - in exact reverse order from the original sound - echo directly and very precisely back to their source point.

Research shows giving Tourette Syndrome patients the drug levodopa normalizes brain activity

Scientists have known for years that abnormal activity involving a brain chemical called dopamine is somehow connected to the movements and vocalizations, or tics, associated with Tourette syndrome. Now neuroscience researchers at Washington University School of Medicine in St. Louis have found brain activity in these patients is abnormal during memory tasks, as well.

GE Healthcare is giving surgeons breakthrough digital mobile imaging system

Surgeons need to clearly see their subject. In the case of minimally invasive surgery, that can be especially challenging because of the small incision or body opening through which they must work. To combat this difficulty, GE Healthcare is giving surgeons "eyes inside the body," with the OEC® FluoroTrak 9800 Plus, a breakthrough digital mobile imaging system.

New treatment for Tourette Syndrome, patients experience significant resolution of symptoms following brain surgery

A neurosurgical team at University Hospitals of Cleveland (UHC) has, for the first time in North America, applied a new surgical approach to the treatment of Tourette syndrome, resulting in the immediate and nearly complete resolution of symptoms for the patient, who has suffered from this neurologic disorder since he was a child.

New Research Information on Tumor Necrosis Therapy

Researchers for Peregrine Pharmaceuticals presented today at the Strategic Research Institute’s Clinical-Stage Product Partnering Summit in La Jolla, CA a summary of clinical experience with Tumor Necrosis Therapy (TNT). The TNT technology is being developed in the U.S. and Europe by Peregrine under the trade name Cotara™. Over 200 patients have been treated with TNT world-wide and a TNT product has been approved to treat grade III or IV advanced lung cancer in the People’s Republic of China. A Cotara registration study for brain cancer has been approved by the U.S. Food and Drug Administration, and a Phase I colorectal cancer study is on-going at Stanford University Medical Center.
