Dr. Valentin Fuster, one of the world's leading cardiologists, discusses the basics of coronary heart disease. Dr. Fuster than describes the symptoms of a heart attack and how to differentiate these symptoms from other conditions. Most importantly, he urges viewers to pay attention to these symptoms and the importance of getting medical treatment as soon as possible, even if one has the least suspicion of a coronary incident. Getting treatment in the first hour or two can minimize damage to heart muscle.

Video Games Beneficial for.. Surgeons?

2008-02-20

Trainee surgeons playing video games before they head into simulated surgery? Sounds like a recipe for disaster, but the Bannar Good Samaritan Medical Center in Phoenix has found it may be time well spent. The Nintendo Wii video game system uses a novel "Wiimote" control system, which allows players to direct on-screen interaction using a wireless wand that detects three dimensional movement. New software is now being designed to accurately simulate surgical procedures, which might be more practical than traditional virtual training tools, which are typically more expensive.

What is Gastroenterology?

2007-11-09

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.

What is Renal Stenosis?

2007-10-09

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.

Bariatric Surgery Found to Lower Risk of Death

2007-08-23

Obesity is on the rise, and so are associated health risks like diabetes, high blood pressure, cardiovascular disease, and sleep apnea. Although once believed to be a risky and rare procedure, bariatric surgery is becoming a prevalent option for people who suffer from morbid obesity. Over 175,000 patients underwent bariatric surgery last year and the number is expected to grow this year. Although there are risks in undergoing these procedures, the surgery death rate has fallen over the years as the technique becomes more sophisticated and less invasive.

Human Stem Cells Return Motor Function to Paralyzed Rats

2007-06-18

Researchers from the University of California, San Diego report that experimental rats recovered from blood flow related paralysis after receiving grafts of human spinal stem cells. When damage occurs due to loss of blood flow to the spine's neural cells, applying human neural stem cells directly to the spinal cord achieves recovery of motor function. In this specific type of paralysis, known as spinal cord ischemia, there is no mechanical damage to the spinal cord. The brain motor centers remain partially connected to the spinal cord but the loss of inhibitory neurons leads to the degeneration of muscle control in lower limbs.
