minimally invasive procedure is the new gold standard for hemorrhoidectomy, according to American and European experts in the field. The procedure, known as PPH (procedure for prolapse and hemorrhoids) stapled hemorrhoidectomy, combines hemorrhoidal devascularization and repositioning to return the veins to the anal canal. “This year, this is the revolutionary new procedure in the United States,” Gary Hoffman, MD, clinical faculty member in general and colorectal surgery, Cedars-Sinai Medical Center, Los Angeles, told General Surgery News after moderating a live PPH telesurgery at the 2003 annual meeting of the Society of American Gastrointestinal Endoscopic Surgeons.
Despite the effective diagnostic and treatment options available today, Dr. Wolfe notes that he continues to see a high number of untreated scaphoid fractures that have progressed to nonunion. However, he adds that this may not be the result of a missed diagnosis, but rather more related to the relatively innocuous injury that causes a low level of suspicion. Recognition and awareness of scaphoid fractures is higher today among primary care providers, emergency room physicians, pediatricians, and sports trainers, but fully 15% of patients with suggestive physical findings and normal initial x-rays will have an “occult”, or concealed, scaphoid fracture. Specialized imaging studies are critical at an early stage to reduce the chance of scaphoid nonunion.
Panic attacks involve sudden feelings of terror that strike without warning. These episodes can occur at any time, even during sleep. People experiencing a panic attack may believe they are having a heart attack or they are dying or going crazy. The fear and terror that a person experiences during a panic attack are not in proportion to the true situation and may be unrelated to what is happening around them. Most people with panic attacks experience several of the following symptoms:
The cause for TS is unknown. Early research suggested that TS is an inherited condition (often, the person's near or distant relatives have had some form of transient or chronic tic disorder or associated symptoms). Recent studies point to a combination of environmental and genetic factors as a cause of the disorder. The specific genes involved in the development of TS are still being investigated. Studies suggest that TS has a neurological basis and results from an abnormality which affects the brain's metabolism of certain neurotransmitters (chemicals in the brain that regulate behavior.) Current research being funded by the Tourette Syndrome Association (TSA) will help provide more information about the causes and genetic factors of TS.
Cholelithiasis involves the presence of gallstones (see the image below), which are concretions that form in the biliary tract, usually in the gallbladder. Choledocholithiasis refers to the presence of 1 or more gallstones in the common bile duct (CBD).
Alcoholic liver disease is a term that encompasses the liver manifestations of alcohol overconsumption, including fatty liver, alcoholic hepatitis, and chronic hepatitis with liver fibrosis or cirrhosis. It is the major cause of liver disease in Western countries.
Behcet's (beh-CHETS) disease, also called Behcet's syndrome, is a rare disorder that causes blood vessel inflammation throughout your body. The disease can lead to numerous signs and symptoms that may seem unrelated at first. They may include mouth sores, eye inflammation, skin rashes and lesions, and genital sores. The effects of Behcet's disease vary from person to person and may clear up on their own. Treatment involves medications to reduce the signs and symptoms of Behcet's disease and to prevent serious complications, such as blindness.
This form of liver cancer is called primary liver cancer. Noncancerous, or benign, liver tumors are common. They do not spread to other areas of the body, and they usually do not pose a serious health risk. In most cases, benign liver tumors are not detected because they cause no symptoms.

The cardiac conduction system is a group of specialized cardiac muscle cells in the walls of the heart that send signals to the heart muscle causing it to contract. The main components of the cardiac conduction system are the SA node, AV node, bundle of His, bundle branches, and Purkinje fibers.
The heart and circulatory system (also called the cardiovascular system) make up the network that delivers blood to the body's tissues. With each heartbeat, blood is sent throughout our bodies, carrying oxygen and nutrients to all of our cells.
Although your body may harbor the bacteria that cause tuberculosis, your immune system usually can prevent you from becoming sick. For this reason, doctors make a distinction between: Latent TB. In this condition, you have a TB infection, but the bacteria remain in your body in an inactive state and cause no symptoms. Latent TB, also called inactive TB or TB infection, isn't contagious. It can turn into active TB, so treatment is important for the person with latent TB and to help control the spread of TB. An estimated 2 billion people have latent TB. Active TB. This condition makes you sick and can spread to others. It can occur in the first few weeks after infection with the TB bacteria, or it might occur years later. Signs and symptoms of active TB include: Coughing that lasts three or more weeks Coughing up blood Chest pain, or pain with breathing or coughing Unintentional weight loss Fatigue Fever Night sweats

Vascular dementia is a general term describing problems with reasoning, planning, judgment, memory and other thought processes caused by brain damage from impaired blood flow to your brain. You can develop vascular dementia after a stroke blocks an artery in your brain, but strokes don't always cause vascular dementia. Whether a stroke affects your thinking and reasoning depends on your stroke's severity and location. Vascular dementia also can result from other conditions that damage blood vessels and reduce circulation, depriving your brain of vital oxygen and nutrients
