New TB Diagnostic Test, Potential Cold Sore Cure, Broccoli Helps Prevent Prostate Cancer

(July 3, 2008 - Insidermedicine) From Geneva - The World Health Organization has unveiled a new diagnostic test that can tell whether patients have drug-resistant tuberculosis within hours, instead of months, and can be used to determine from a person's saliva whether the tuberculosis can be treated with antibiotics.

(July 3, 2008 - Insidermedicine) From Geneva - The World Health Organization has unveiled a new diagnostic test that can tell whether patients have drug-resistant tuberculosis within hours, instead of months, and can be used to determine from a person's saliva whether the tuberculosis can be treated with antibiotics. Tuberculosis is a contagious respiratory disease that kills 1.5 million people each year.

From North Carolina - Researchers believe that a cure for the virus that causes cold sores is on the horizon. Cold sores, which typically appear as painful ulcers around the mouth, are caused by the herpes simplex virus, which usually lies dormant. Researchers have discovered how the virus becomes activated and believe a treatment can be developed which includes artificially activating the virus, and then killing it with antiviral medication.

And finally, from London - Including broccoli in one's diet may help protect men from prostate cancer. Researchers asked men at risk for prostate cancer to eat 4 servings of broccoli each week. After taking tissue samples from the men's prostate glands the researchers found that eating broccoli changed how certain genes behaved, reducing the risk of developing prostate cancer, and preventing the disease from becoming more aggressive.

Modifying Athletic Screening Programs to Prevent Sudden Death

(July 3, 2008 - Insidermedicine) A comprehensive screening program for athletes should include both a resting and exercise electrocardiogram to identify those with heart abnormalities that place them at risk for sudden death, according to research published in the British Medical Journal.

(July 3, 2008 - Insidermedicine) A comprehensive screening program for athletes should include both a resting and exercise electrocardiogram to identify those with heart abnormalities that place them at risk for sudden death, according to research published in the British Medical Journal.

Here is some information about sudden death in athletes:

•    Some estimates suggest that as many as 1 in 15,000 joggers or 1 in 50,000 marathoners experience sudden death.

•    In an athlete, sudden death usually occurs during or immediately after exercise.

•    The most common causes of sudden death in athletes relate to abnormalities of the heart and cardiovascular system.

Researchers out of the Institute of Sports Medicine at the University of Florence analyzed data from over 30,000 athletes who underwent pre-participation cardiovascular screening, including resting and exercise ECG. ECG records the electrical activity of the heart and abnormal findings could be a sign of a heart disorder associated with a risk for sudden cardiac death.

While only 1.2% of the athletes had abnormal results on the resting ECG, 4.9% had abnormal findings using exercise ECG. The exercise ECG was more likely to pick up abnormalities in older athletes. Among the 159 athletes disqualified because of the results of their exercise ECG, 95% would have been missed by history and physical examination alone, and 80% would have been missed by resting ECG.

Today's research demonstrates how the addition of both resting and exercise ECG to the pre-screening of competitive athletes could save lives.
