First Face Transplant Done in America

In Cleveland, reconstructive surgeon Dr. Maria Siemionow and a team of specialists performed the first face face transplant done in America by replacing 80 percent of a disfigured woman's face by using the face of a female cadaver. Many details of the surgery have not been released but surgeons that do this usually transplant skin, facial nerves, muscles, and other deep tissue.

Skin is considered an organ and it still runs the risk of the body rejecting it, as with other organ transplants. Recipients of transplants have the risk of deadly complications, such as the new facial tissue attacking the recipient's body and the recipient's body attacking the bone marrow or the transplanted face to cause inflammation at the area of the new tissue. They also have to take immune-suppressing drugs for the rest of their lives to prevent the body rejecting the organ. This raises the risk of cancer and other diseases.

This is the fourth one done worldwide. Two have been done in France and one was done in China. The first one was a partial face transplant done in France in 2005 on a woman who had been mauled by her dog and received a new nose, chin, and lips from a brain-dead donor. Another was done in France on man disfigured by a genetic disease. One was done in China on a farmer that had been disfigured by being mauled by a bear.

Global Warming Increases Allergy Problems

It is found that climate change due to global warming can affect allergies. Global warming and increased atmospheric carbon dioxide levels from burning fossil fuels can increase the levels of pollen that cause allergies. The effect of global warming and increased carbon dioxide levels on allergies are currently being studied by government agencies, scientists, and doctors. The Intergovernmental Panel on Climate Change and the Environmental Protection Agency have both cited increased allergic reactions due to climate change as a growing concern for the public in 2007 reports.

Cocaine Could Cause Heart Attack Symptoms

The American Heart Association is warning doctors that younger ER patients with heart attack symptoms should be asked if they had recently used cocaine. Some heart attack treatments can be deadly to a person that is using cocaine. Symptoms of a heart attack in younger people that don’t have a heart disease risk could be caused by cocaine use.

Cocaine can cause chest pains, shortness of breath, anxiety, palpations, dizziness, nausea, and heavy sweating, which are all symptoms of a heart attack. Cocaine use can cause a heart attack but that only happens in 1 to 6 percent of people with chest pain caused by cocaine. It is important for anybody that has chest pains for any reason to get it checked out. Cocaine works by increasing blood pressure and heart rate. It also constricts the arteries into the heart. The heart rate would go up because the heart would need more oxygen and arteries that go to the heart would shrink.

Cocaine users that go to the hospital due to chest pains should be given an electrocardiogram and other tests to rule out a heart attack. They should be monitored and not admitted to the hospital as having a heart attack. Users with chest pains should not be treated with clot busting drugs because they have a risk of bleeding into the brain in people with high blood pressure. Betablockers should be avoided because they would raise blood pressure and squeeze arteries that are already narrowed by the cocaine. It is recommended that cocaine users that have a coronary artery blockage get a bare metal stent instead of a drug-coated one since drug users may not take the medication as needed to prevent new blockages.

The Healing Powers of Magnets

A recent study has found that magnets have the ability to increase blood flow and reduce inflammation. Researchers at the University of Virginia used powerful magnets on the paws of injured rats and measured the blood flow to the area. They found that the magnetic field caused by the magnets opened tiny blood vessels and increased the oxygen and nutrients to damaged tissues. Swelling was also reduced by 50 percent.

If the same results are found in humans, then doctors have the possibility of using magnets as another option for treating conditions, such as sprains and bruises.

New Medical Treatment for Heart Attacks

It is assumed that if a person is not revived 5 minutes after having cardiac arrest that they are basically dead. Researchers have found that if the body of a person that had cardiac arrest is cooled by several degrees after the heart has stopped beating, the person could survive for up to 15 minutes instead of 5 minutes. Doctors are starting to use cooling blankets that circulate icy water to reduce brain damage and revive people that didn’t have a heart beat for up to 15 minutes. Researchers are trying to develop icy injectable slurry that lowers body temperature within seconds and emergency workers can use it on the spot.

Study Says Some People Having AIDS Aren’t Infectious

It is found in a recent study that AIDS patients that have been treated with the latest antiretroviral drugs can no longer infect other people through sexual contact. The drugs work so well that even though the patients aren’t cured, they make it able that only a small amount of the virus is circulating through the body. Researchers say that this fact prevents a HIV-positive person from transferring the virus through sexual intercourse.

The researchers also say that AIDS patients who took the drugs for at least six months can have unprotected sex with HIV-negative people without infecting them. Many activists and doctors don’t agree with doing this because it might have HIV-positive people having sex without informing their partners about their disease. If a HIV-positive patient missed a dose of their medicine, then they could be at risk of infecting their partners.
