...Andrew Einstein, a cardiologist at the Columbia University College of Physicians and Surgeons, researchers calculated the lifetime attributable cancer risk associated with radiation exposure from a single scan (called computer tomography coronary angiography, or CTCA), based on the patient's sex and age. For example, the lifetime cancer risk following one CTCA was just 1 in 3,261 for an 80-year-old man; that risk jumped to 1 in 284 for a 40-year-old woman, and climbed higher still to 1 in 143 for a 20-year-old woman. At all ages for women, the risk of breast...
...ranging from 0.02% (for an 80-year old man, with the dose-reduction strategy) to 1% (for a 20-year-old woman, with a regular heart and aorta scan). The benefits of CTCA are that it is noninvasive, quick (the test takes about 10 minutes), requires that the patient ingest less contrast dye than with other scans and can be performed immediately in an emergency room when someone is admitted with chest pain. According to the study's authors, emergency departments evaluate about 6 million patients each year for chest pain...
...Because of the potential hazards involved with radiation exposure, Einstein warns patients against attempts to "get pretty pictures of their heart" without a doctor's recommendation. Otherwise, he says, the CTCA can be an excellent noninvasive alternative to the current gold standard test for heart disease, the coronary angiography, which involves threading a catheter from the groin to the heart's blood vessels, and can cause complications such as blood clots, infection and even death. CTCA is also a good substitute for the time-consuming diagnostic tests in use in emergency departments; with CTCA physicians can find out sooner when...
...before we enter the theater. Fascinating as these characters are, interesting as the events of its chase often are, we cannot escape the fact that the movie's ending is known to us, that history's course cannot be altered. We can (and do) admire Mariane's courage, the patient tenacity of the "The Captain" (Irrfan Khan) the lead Pakistani investigator, the sweetness of Dan Futterman's portrayal of Danny Pearl. But what we have, in essence, is a kind of police procedural in which the procedures do not bear fruit...
Charles Krauthammer's foreign policy column After Sept. 11 Krauthammer wrote about a radical and dominant approach to foreign policy, which the Bush Administration adopted. Now the next President will need to be an international expert, have a style of patient diplomacy and preferably have spent some time overseas or in the military...
