A brain (cerebral) aneurysm is a bulging, weak area in the wall of an artery that supplies blood to the brain. In most cases, a brain aneurysm causes no symptoms and goes unnoticed. In rare cases, the brain aneurysm ruptures, releasing blood into the skull and causing a stroke. When a brain aneurysm ruptures, the result is called a subarachnoid hemorrhage. Depending on the severity of the hemorrhage, brain damage or death may result. The most common location for brain aneurysms is in the network of blood vessels at the base of the brain called the circle of Willis. What causes a brain aneurysm? A person may inherit the tendency to form aneurysms, or aneurysms may develop because of hardening of the arteries (atherosclerosis) and aging. Some risk factors that can lead to brain aneurysms can be controlled, and others can't. The following risk factors may increase your risk for an aneurysm or, if you already have an aneurysm, may increase your risk of it rupturing: Family history. People who have a family history of brain aneurysms are more likely to have an aneurysm than those who don't. Previous aneurysm. People who have had a brain aneurysm are more likely to have another. Gender. Women are more likely to develop a brain aneurysm or to suffer a subarachnoid hemorrhage. Race. African Americans are more likely than whites to have a subarachnoid hemorrhage. High blood pressure. The risk of subarachnoid hemorrhage is greater in people who have a history of high blood pressure. Smoking. In addition to being a cause of high blood pressure, the use of cigarettes may greatly increase the chances of a brain aneurysm rupturing.
What Are Sleep Disorders? Circadian Rhythm Disorders Typically, people sleep at night -- thanks not only to the conventions of the 9-to-5 workday, but also to the close interaction between our natural sleep and alertness rhythms, which are driven by an internal "clock." This clock is a small part of the brain called the suprachiasmatic nucleus of the hypothalamus. It sits just above the nerves leaving the back of our eyes. Light and exercise "reset" the clock and can move it forward or backward. Abnormalities related to this clock are called circadian rhythm disorders ("circa" means "about," and "dies" means "day"). Circadian rhythm disorders include jet lag, adjustments to shift work, delayed sleep phase syndrome (you fall asleep and wake up too late), and advanced sleep phase syndrome (you fall asleep and wake up too early).
Hepatitis B is a serious disease caused by a virus that attacks the liver. The virus, which is called hepatitis B virus (HBV), can cause lifelong infection, cirrhosis (scarring) of the liver, liver cancer, liver failure, and death. Hepatitis B vaccine is available for all age groups to prevent HBV infection.

Three to five years after gastric bypass surgery, some patients start to regain weight because the size of their stoma (the opening at the bottom of the stomach pouch) or their stomach pouch itself has increased. This can keep you from feeling full after small meals.
To resolve this problem, our surgeons use new surgical tools to create and suture folds into the pouch, reducing its volume and at the stoma to decrease its diameter. The surgeon performs the procedure entirely through the mouth -- inserting an endoscope under heavy sedation -- so there are no external incisions into the body.
