MRI Excels at Detecting Wrist Ligament Tears
The most advanced magnetic resonance imaging (MRI) machine is nearly as effective as going in surgically to detect tears in wrist ligaments, according to a recent study.
The author of the paper in the American Journal of Roentgenology, Thomas Magee of Neuroskeletal Imaging in Merritt Island, Fla., examined the magnetic resonance (MR) wrist images of 300 patients at his community imaging service. The scans were performed with a so-called 3-Tesla MRI machine, which is twice the magnetic strength of the most common system, the 1.5-Tesla MRI.

Two Markers Found for Prostate-Cancer Deadliness
Investigators have found that men who are or have been overweight or who have high insulin levels are more likely to die from prostate cancer. The discovery of these two predictors is important, because doctors now have two crucial clues as to which patients will develop the most life-threatening tumors and therefore which to treat most aggressively.

African American Women and Breast Cancer
“I was afraid that I wouldn’t be able to see my children grow up and my grandchild grow, you get this really scary feeling inside,” says Rosamond Stallings. When 45 year old Rosamond Stallings was diagnosed with breast cancer 2 years ago, doctors urged her to immediately have a mastectomy. “They found like six malignant tumors,” says Rosamond. Recent studies have shown that 30 percent or more of breast cancer patients fail to receive complete treatment, and that African American women are as much as 10 percent less likely than white women to receive optimal therapy. But now, supported by a $10 million grant from the Department of Defense, a study, led by a team of doctors at Columbia University Medical Center, will look at possible reasons for the disparity.

How Real is the Threat of Pandemic?
Dr. John Cahill explains that our world is becoming increasingly small and easy access air travel and global urbanization has created the possibility for the very real threat of pandemic. The internet has made international travel quick and easy and soon a majority of the global population will live in close quarter urban environments. A good example is SARS, which started in China, made its way to Hong Kong, and spread throughout the world rapidly. More recently, though there have not been a large number of reported cases, Avian Influenza has the potential to be a serious threat to public health. If someone with the common Flu were to meet someone with Avian Influenza, there is a very real possibility that the two could mutate into something very virulent and spread rapidly.

A Crisis In Modern Scientific Education
Dr. Valentin Fuster discusses a crisis in modern scientific education. For Dr. Fuster the crisis is not a lack of technical skill, but lack of creativity. Dr. Fuster explores how science, and specifically medical education, has become overly oriented to our present technological world at the expense of creativity. He also urges scientist and their students to be open enough to be aware of the social implications of their work, For example, extending cell life may have great implications for extending a human life, but then we should be aware of the social implications of such research as well. He also emphasizes how real innovation comes from creativity not technical expertise. Read more about A Crisis In Modern Scientific Education
What is Gastroenterology?
Video: Dr. Jonathan Cohen of the Concorde Medical Group discusses Gastroenterology. Gastroenterology is a specialized field of medicine that focuses on the digestive tract - from the mouth to the anus. Gastroenterolgy studies the functioning and disorders of the esophagus, stomach and intestines, as well as its associated organs such as the liver, pancreas and gall bladder. There is documented evidence that some forms of Gastroenterolgy were practiced in ancient Egypt. Greek, Roman and Arab practitioners studied the digestive tracts of the human body with specially designed spatula and mirrors illuminated by candles or oil lamps. More complex tools for examining the rectum with dilating specula were found in the ruins of Pompeii. Read more about What is Gastroenterology?
What is Renal Stenosis?
It is very interesting that a lot of people don't know that blocking the arteries of the kidney can be a cause for hypertension. Particularly someone who is young and becomes hypertensive suddenly, one should make sure there is no blockage in the renal arteries. There are millions of people with hypertension, so it's easy to think that we should simply give them medications. But it's important to understand that there is a very small segment of the population, who develop hypertension at a young age, particularly in their twenties, thirties, forties. They need to be looked into. All we need to do is a scan of their kidneys. What is called a duplex scan or an ultrasound of their arteries. With this methodology we can actually pick up a narrowing of the arteries. Read more about What is Renal Stenosis?
What is Peripheral Arterial Disease?
Dr. Sattesh Babu of Vascular Associates of Westchester discusses Peripheral Arterial Disease, who is at risk, why it is important to be screened and current treatments. Pad is essentially a blockage of the arteries in the lower extremities. That is what we mean by peripheral arteries -- leg arteries blocked by hardening of the arteries, buildup of cholesterol, plaque and calcium. This in part is a process of aging, but certainly also brought on by smoking. Diabetes is another risk factor, as is hypertension. Read more about What is Peripheral Arterial Disease?
