In a prospective study of nearly 5000 postmenopausal women, it was determined that it would take 16.8 years to develop osteoporosis in 10% of women with normal bone mineral density. The authors conclude that repeat screening in women without new risk factors can be delayed for at least 15 years.

Within a few years after the initiation of diagnostic X-rays, toxic effects were noted, including increased risk for skin cancer, leukemia, dermatitis, and cataracts. In this early period, doses of X-ray, especially from fluoroscopy, were high. Protective devices for patients as well as persons occupationally exposed to diagnostic radiation demonstrably reduced such adverse consequences.

The authors conclude that in patients hospitalized with myocardial infarction, women were more likely than men to present without chest pain and had higher mortality than men within the same age group.

Patients with hypertension and diabetes mellitus can be stratified into a lower cardiovascular risk group in the absence of coronary artery calcium.

Scenario: The 12-lead ECG shown above was obtained from a previously healthy 30-year-old man who presented to the emergency department with new-onset palpitations. No prior ECG was available for comparison. The patient was alert and hemodynamically stable at the time this tracing was recorded. What is the rhythm? Is this rhythm likely to respond to adenosine?

Antipsychotic drug use may increase the risk of myocardial infarction in elderly patients with dementia.

A combination histamine-1 receptor antagonist and a corticosteroid nasal spray has been approved by the FDA for the treatment of seasonal allergic rhinitis.

Radiation exposure from ct is quite substantial. A "typical" abdominal CT (AB-CT) examination exposes a patient to X-radiation equivalent to more than 500 chest X-rays.

New data from the Women's Health Initiative Study estrogen-only arm demonstrates that estrogen treatment not only was associated with a lower incidence of breast cancer diagnosis, but also fewer breast cancer deaths.

This brief but important intervention trial was detailed recently in the pages of the Journal of the American Medical Association. The conclusion was that eating canned soup on a regular basis could rapidly increase the body load of BPA, high levels of which have been associated with a variety of illnesses.
