Last week brought the first modest success story in this new field of "chemo-prevention." Dr. Waun Ki Hong and colleagues from the University of Texas in Houston reported evidence that some cancers can be thwarted by isotretinoin, a man-made derivative of vitamin A that is sold as an anti-acne medication under the brand name Accutane. Fifty patients who had been successfully treated for cancer of the mouth and throat were given large daily doses of the drug for 12 months. After as much as three years, only two (4%) of the subjects developed a new cancer...

Medical applications are also being rapidly developed.

By having a patient swallow the pill, doctors can pinpoint worrisome hot spots anywhere within the digestive tract. Future "smart pills" may transmit information about heart rates, stomach acidity or neural functions. Says Russell Eberhart, program manager at Johns Hopkins' Applied Physics Laboratory: "This could change the way we diagnose and monitor patients...

Tseng, an ophthalmology fellow, had apparently acted unethically in his research. Tseng was found by the University to have exaggerated results of his experiments on a vitamin A treatment for dry-eye disease while owning substantial stock in the company that manufactures the drug...
