People with Alzheimer's face an awkward juncture in the near future. They'll be able to learn early on whether they have Alzheimer's disease -- even if they can't do much about it. With therapies to halt or slow the progression of Alzheimer's disease seeming ever more elusive, several blood tests currently in development could determine who has the disease even before symptoms develop or become severe.

In assessing heart disease and deciding how to treat it, physicians rely on the angiogram as the standard diagnostic test. More than 1 million angiograms--special X-rays showing the inside of blood vessels--are performed in the United States each year. Based on the results of this test, surgeons performed 285,000 artery-clearing procedures called angioplasty and 380,000 heart bypass operations in 1990.

Amid signs that the world's first SARS outbreak may have run its course, a leading World Health Organization official warned Thursday that detecting any recurrence of the pneumonia-like disease next winter will pose an entirely new set of medical challenges.

A diagnostic test for cancer that could revolutionize screening for the deadly disease has been developed by researchers at Johns Hopkins Medical Institutions. The new test, reported in today's issue of Proceedings of the National Academy of Science, identifies replication errors in DNA that occur frequently in cancer. The errors, known as clonal markers, are used as a fingerprint for cancer.

Ovarian cancer is uncommonly deadly. Tumors aren't usually detected until the disease has spread beyond the ovaries, at which point only a third of patients survive more than five years. A promising blood test could change this bleak picture, enabling doctors to identify ovarian cancer at its earliest, most treatable stage. "This has the potential of being an important advance," says Dr. Philip DiSaia, director of gynecological oncology at the UC Irvine School of Medicine.

For busy people, time is money. And when you've got more money than time, the cost of an executive physical examination is kind of like the price of a yacht. If you have to ask, you can't afford it. Tom Gilmore arrived at L.A.'s Good Samaritan Hospital on a bright Friday morning, sporting a dark blue Nike warmup suit the hospital had sent.
