Charlotte Cox lies on a table with 22 green, red, blue and yellow electrodes glued to her head. As she relaxes, the electroencephalograph machine she is wired to steadily spits out reams of graph paper filled with black zigzagging lines. Across the room, a fellow classmate, also sprawled out on a laboratory table, is having his head blown dry with an air hose so wires can be secured to his skull.

A lot of us find our way to the doctor with strange aches and pains that are very, very unlikely to be caused by serious illness -- headaches, back pains or stomach troubles, to name a few. To be on the safe side, physicians will often order tests to rule out the scary stuff and, the thinking goes, provide reassurance.  But a recent examination of 14 randomized, controlled trials found that ordering diagnostic tests for people who have a low...

Double-murder charges against a 35-year-old Van Nuys man accused of raping and killing two female transients were dismissed Wednesday because DNA tests showed that someone else sexually assaulted one of the victims. Steven C. Leigh, described as a satanist and white power advocate, remains a suspect in the murders of Dawn McGrath, 21, and Jamie J. Jensen, 13, found shot Jan. 20, prosecutors said. However, Leigh's attorney, Bruce C.

Even among psychiatric disorders, depression is a difficult disease to diagnose. Its causes remain a mystery, its symptoms can't be defined with precision, and treatments are spotty at best. But that may soon change. Scientists are looking for ways to identify patients with depression as reliably as they diagnose cardiovascular disease, diabetes and cancer. A new study takes a significant, though preliminary, step in that direction by demonstrating that a simple blood test can distinguish between people who are depressed and those who are not. The test examined a panel of 28 biological markers that circulate in the bloodstream and found that 11 of them could predict the presence of depression at accuracy levels that ranged from medium to large.

Consider two takes on Christopher Hubbart, serial rapist. State psychologist No. 1: He is a bright, shy 43-year-old man who is trying to control his sexual urges, and is truly sorry for his 34 victims. State psychologist No. 2: He is dangerous, unable to control his sexual urges and can be counted on to rape again.

ICN Pharmaceuticals Inc. said Tuesday that federal regulators recently approved its diagnostic test for a metabolic disorder in newborns. The test detects the hereditary disorder galactosemia, which, if left untreated, can cause liver and brain damage, the drug company said. Early diagnosis enables the doctor to prescribe a special diet to reduce harmfully high sugar levels in an infant's blood. The federal Food and Drug Administration in November approved the test for marketing.

Eva Engvall is a scientist who breeds Abyssinian cats as an avocation and is reluctant to name the kittens lest it become harder to part with them. That was not a problem with something as distant from cats as enzyme-linked immunosorbent assay, a diagnostic test that she helped pioneer while a young graduate student at the University of Stockholm and which she gave the melodious name of ELISA. Since then, someone else patented the test and another company trademarked the name.

Two independent teams of medical researchers announced Thursday that they have succeeded in mapping the approximate location on human chromosomes of a genetic defect responsible for the most common inherited disease of the nervous system. The scientists, at Harvard University and Massachusetts General Hospital in Boston and at the University of Utah, said the discovery opens the way for the eventual development of diagnostic tests and possibly for treatment of neurofibromatosis, or NF.

Beckman Instruments Inc. said Friday that it has agreed to acquire the once-soaring Hybritech Inc. medical test manufacturer from its parent company, drug maker Eli Lilly Co., for an undisclosed price. The acquisition of Hybritech, with annual sales of about $80 million, would boost Beckman's revenue to $1 billion and help round out the Fullerton company's line of diagnostic tests, industry analysts said. Beckman also makes and sells medical instruments and supplies.

Water won't wait Re "Messing with Devil's Gate," Editorial, May 6 I lived in La Crescenta during the great flood of 1938. I remember listening to radio reports that Devil's Gate Dam was in imminent danger of collapsing. Fortunately it didn't, and the Arroyo Seco and the communities below were saved from a deluge of mud and water. The fact that the dam's basin has been allowed to fill with sediment over the years is a sign of ignorance and mismanagement. The L.A. County Board of Supervisors should make clearing out the basin a top priority.

A new automated test to detect tuberculosis infections and the presence of an antibiotic-resistant TB strain can shave days to weeks off the time it takes to identify new infections, allowing treatment to be started immediately to prevent further spread of the bacterium. The new test, which can be performed by technicians with only limited training, could prove highly valuable not only in the developing world, but also in the inner cities of the developed world where outbreaks of the deadly disease are becoming more common.

The dollars saved are nearly negligible, but the political costs of scaling back breast cancer screening for tens of thousands of low-income women have turned out to be huge. Twenty-one members of California's congressional delegation -- Republicans and Democrats alike -- have sent a letter rebuking the governor for the move. State lawmakers are warning that people will die. Audits are being demanded. The Assembly Budget Committee chairwoman is even organizing a symbolic bake sale.

Women in their 40s should begin getting mammograms whenever they want, members of a U.S. advisory group told a House hearing Wednesday, saying their "poorly worded" recommendations last month had confused people. Physicians with the U.S. Preventive Services Task Force told a House hearing that they had not meant to suggest that screenings were unnecessary for patients in that age group. Instead, the physicians said, they meant that screening is more effective for those 50 to 74. Republicans had trumpeted the initial recommendations, issued Nov. 16, as evidence that the Democratic-sponsored healthcare overhaul would lead to rationing of medical care.

Diabetes rates have climbed steeply in this country in the last two decades. Fortunately, scientists' knowledge of how best to manage the disease is advancing as well. Researchers gathered at the American Diabetes Assn. meeting last week in New Orleans to consider the latest developments, including a new test for diagnosing the disease and a better understanding of the risks of aggressive control of blood sugar.

In August, the U.S. Preventive Services Task Force, a government-sponsored panel of medical experts, issued new recommendations regarding prostate cancer screening: Men ages 75 and over should no longer be screened for prostate cancer with the PSA blood test or digital rectal exam. An unexpected benefit may be an improvement in the doctor-patient relationship. The rectal exam can be one of the odder moments between a patient and his doctor.

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. Those stricken with severe acute respiratory syndrome initially carry an extremely low level of the virus, making an immediate diagnosis all but impossible, said the WHO's senior communicable diseases specialist, David Heymann.

The government approved a new genetic test for the flu virus Tuesday that will allow labs across the country to identify flu strains within four hours instead of four days. The time-saving test could be crucial if a deadly new strain emerges, federal health officials said. The new test also could help doctors make better treatment decisions during a conventional flu season. The test was developed by the Centers for Disease Control and Prevention and Applied Biosystems Inc. of Foster City, Calif.

Men over the age of 75 should no longer be screened for prostate cancer because the potential harm from the test results -- both physical and psychological -- outweighs any potential benefit from treatment, a federal panel said Monday. Most oncologists already argue against treating most men in that age group for prostate cancer because they are more likely to die from some other cause than from their tumor.
