Originally published in MedPage Today by Michael Smith, MedPage Today North American Correspondent Brazilian researchers have found three distinct patterns of lung damage in patients who died of the H1N1 pandemic flu.

There's no question that CT scans are among the most overused medical tests. One newer application has been using CT scans to detect coronary artery calcification for primary prevention of heart disease. It's a technology of unproven promise, with entities like the USPSTF recommending against it. Worse, especially in light of the recent data suggesting significant radiation exposure from CT scans, it may even be harmful. Patients need to understand ...

The recent uproar over the new screening mammography recommendations got me thinking about a lot of stuff. One of the lessons cited by some journalists and pundits is on how potentially volatile information should be presented to the public. The USPSTF was excoriated by critics not only for what it said, but how it said it. While the objections over the former can be dismissed as ravings of loud and ...

Hopefully, by now, people are realizing that more is not necessarily better. A new study reported at the American Heart Association 2009 Scientific Sessions showed that patients with acute myocardial infarction (AMI) receive large doses of ionizing radiation per hospital admission. They looked at patients treated at 55 academic hospitals and found, on average, each patient received seven studies per AMI admission. The studies included chest X-rays, chest CT, head CT, ...

Originally published in MedPage Today by Crystal Phend, MedPage Today Senior Staff Writer Many women at elevated breast cancer risk may refuse MRI as part of their screening program, largely because of fear and inconvenience, researchers found. Among eligible women with dense breasts who were at intermediate to high risk for breast cancer, 42.1% refused additional MRI screening as part of a ...

Would you take a pill every day to reduce the risk of breast cancer? That's a question Tara Parker-Pope asks in a recent blog entry. Referring to Tamoxifen, a drug that's been shown to reduce the risk of breast cancer in high-risk women, she notes that a substantial number said they wouldn't take the drug after hearing about the side effects:
