Surgeons develop simpler way to cure atrial fibrillation

...cal procedure that has had the best long-term cure rate for persistent atrial fibrillation. The simplified procedure is termed Cox-maze IV, and the surgeons believe it can replace the older "cut and sew" Cox-maze III in which ten precisely placed incisions in the heart muscle created a "maze" to redirect...

Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

... "Despite great medical progress, the survival rate in head and neck cancer still remains very poor, at about 50 percent, and there is a definite need for new treatment modalities like vaccination," Whiteside said. "Targeting of p53, however, is a strategy that could also work in treating a number of ...

Gene therapy for blindness clears hurdle in mice

...s, followed by loss of their peripheral sight. The rate of progression varies, but most patients are blind by 40. UF Genetics Institute researchers engineered the interfering RNA into a virus, which in turn was injected below the retinas in more than a dozen normal mice. Analysis showed the technique r...

New research shows that flu is a trigger of heart attacks

No-scalpel vasectomies by skilled surgeons may speed recovery

...y is the preferable method to use, as it has lower rate of adverse events," Cook said. "But the no-scalpel technique requires more training and a higher level of skill. One of the most important issues for men seeking a vasectomy is the experience of the surgeon with that particular method." "The no-s...

... less than optimal taxotere regime so the survival rate may have been artificially inflated,' he says. He points out, however, that it may be that the Asentar will eventually prove applicable in the earlier stages of the disease. Prostate cancer is the second leading cause of cancer death in men.

New cigarette designs don't offer lower predicted cancer risks

...hat's observed for the smoking-related lung cancer rate in the population," he said. Grover Bagby, M.D., professor of medicine (hematology and medical oncology) and director of the OHSU Cancer Institute, said "the tobacco industry would have us believe that the health risks of tobacco use can be reduce...

New research may overturn conventional wisdom on drug-resistant tuberculosis

"This overturned the common belief that drug resistance among treated patients is always acquired." The investigators also noted that two patients in the study had multidrug-r...

A steady, high-fat diet is bad, but the news gets worse
