The external pumps are used by many diabetics who need a steady supply of insulin as an alternative to giving themselves numerous injections of the sugar regulator each day. Most models are programmed to constantly release tiny amounts of insulin, mimicking the pancreas, while allowing patients to ring up a larger dose when they eat a meal. Noting research also suggests that electromagnetic radiation, such as that from cellular phones, can affect insulin pump systems, Dr. Nicholas Tritos and his colleagues recommend that users be wary of exposure. Tens of thousands of Americans, many of them in the military, were given nasal radium treatments years ago, a treatment that may increase their risk of developing cancer and other medical problems today. One scientist's quest to bring this to light has finally led to government promises to investigate and help those affected.
Anxiety disorders can wreak havoc with family life, but help is available.
Molecular biologists at the University of Colorado have developed the first map of human chromosome 18, including genes associated with several forms of cancer. There's new evidence about the harm of second-hand smoke. In the near future, stitches for most wounds could be a thing of the past. Doctors find an adhesive closes wounds more quickly and helps them heal as well. Researchers identify a defect in heart cells that may explain why the muscle loses its ability to pump blood in people suffering from hypertension and perhaps other types of heart failure.
