The researchers will test the possibility that the symptoms of MS result from narrowing of the primary veins outside the skull, a condition called "chronic cerebrospinal venous insufficiency," or CCSVI. http://www.physorg.com/news174760709.html Medicine & Health Wed, 14 Oct 2009 17:39:06 EST news174760709 (PhysOrg.com) -- Penn State Milton S. Hershey Medical Center recently became only the third hospital in Pennsylvania and one of only about 30 institutions in the country to offer a new minimally invasive treatment for brain aneurysms. Brain aneurysms are balloon-like out-pouchings that can develop in brain arteries. Like balloons, these out-pouchings can burst, causing a devastating type of stroke as blood leaks in and around the brain. This new treatment uses a liquid, glue-like substance called Onyx HD to completely fill aneurysms from the inside of the blood vessel, thereby preventing them from ever bleeding or causing a stroke. http://www.physorg.com/news174144542.html Medicine & Health Wed, 07 Oct 2009 19:40:01 EST news174144542 (PhysOrg.com) -- Heart patients who receive specific instructions about how to respond to chest pain or heart attack symptoms still don`t seek immediate care, according to a new study published in Circulation: Cardiovascular Quality and Outcomes. http://www.physorg.com/news174149240.html Medicine & Health Wed, 07 Oct 2009 16:00:01 EST news174149240 The organs of the inner ear have a direct effect on brain blood flow, independent of blood pressure and CO2 levels in the blood.
