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.

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.

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.
