What is a Whipple procedure?
Also called a pancreaticoduodenectomy, the Whipple procedure is performed to address chronic pancreatitis and cancer of the pancreas, ampulla of Vater, duodenum, and the distal bile duct. The Whipple procedure involves removing the cancerous parts of the pancreas, duodenum, common bile duct, and if required, part of the stomach.
Ventricular tachycardia is a type of heart rhythm disorder (arrhythmia) in which the lower chambers of your heart (ventricles) beat very quickly because of a problem in your heart's electrical system. In ventricular tachycardia, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast that they don't have time to properly fill. Ventricular tachycardia may be brief — lasting for just seconds and often not causing symptoms — or it can last for much longer, and you can develop symptoms such as dizziness or lightheadedness, or you can even pass out. This condition usually occurs in people with other heart conditions, such as coronary artery disease, cardiomyopathy and some types of valvular heart disease. Ventricular tachycardia may lead to a condition in which your lower heart chambers quiver (ventricular fibrillation), which may cause your heart to stop (sudden cardiac arrest) and lead to death if not treated immediately. Ventricular tachycardia can also cause your heart to stop, especially if the heart is beating very quickly, if it's lasting for a long period, and if you have an underlying heart condition.
Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.
Heavy period blood can be especially alarming if it contains clots. In most cases, though, red, brown, or even black menstrual blood clots are normal—just bits of the endometrium (the lining of the uterus) that are shed during menstruation.
The infection is generally transmitted by direct contact with the mucus or sores of someone else with strep. Common symptoms include sore throat, fever, and swollen lymph nodes in the neck. Rarely, complications can involve the heart or kidneys. Treatment is important to reduce complications. Oral antibiotics like penicillin, amoxicillin, cephalexin, or azithromycin are commonly used. Other medicines such as acetaminophen or ibuprofen can help with pain and fever.
Giant cell arteritis is an inflammation of the lining of your arteries. Most often, it affects the arteries in your head, especially those in your temples. For this reason, giant cell arteritis is sometimes called temporal arteritis. Giant cell arteritis frequently causes headaches, scalp tenderness, jaw pain and vision problems. If left untreated, it can lead to stroke or blindness. Prompt treatment with corticosteroid medications usually relieves symptoms of giant cell arteritis and may prevent loss of vision. You'll likely begin to feel better within days of starting treatment. But even with treatment, relapses are common. You'll need to visit your doctor regularly for checkups and treatment of any side effects from taking corticosteroids.
http://www.mediplus.co.uk A new and safer method of inserting a Foley catheter suprapubically. The technique allows the insertion to be carried out in an Outpatient setting, thus saving time, cost and effort. By using the Seldinger technique, the product reduces the chances of bowel or bladder perforation and resultant morbidity.
The product has been chosen by The NHS National Technology Adoption Centre to help facilitate adoption of the product.
What combines research opportunities, intellectual challenge, and international collaboration in the study of a disease which affects many organs of the body and all sectors of society? And demands that specialists from many different backgrounds work together to crack sometimes intractable problems? It is, of course, oncology. As a career choice, it's demanding; it takes passion coupled with a willingness to put in the hours and to learn how to discuss death honestly and sensitively. But for the right person, it can be immensely rewarding.
A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children. A chronic cough is more than just an annoyance. A chronic cough can interrupt your sleep and leave you feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness and even rib fractures. While it can sometimes be difficult to pinpoint the problem that's triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.
What is a brain aneurysm? 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.
Asbestosis is linked to chrysotile fibers. Chrysotile is one of the six known types of asbestos. Exposure occurs when someone breathes in the dangerous fibers. Extended exposure can lead to an accumulation of the fibers in lung tissues, setting the stage for long-term fibrosis (scarring). Over time, lung tissues thicken, causing pain and restricting breathing. Symptoms include labored breathing during routine tasks and exercise, chest pain and coughing. Doctors prescribe breathing treatments, prescription medication and sometimes surgery for people with asbestosis.
An abdominal aortic aneurysm is an enlarged area in the lower part of the aorta, the major blood vessel that supplies blood to the body. The aorta, about the thickness of a garden hose, runs from your heart through the center of your chest and abdomen. Because the aorta is the body's main supplier of blood, a ruptured abdominal aortic aneurysm can cause life-threatening bleeding. Depending on the size and the rate at which your abdominal aortic aneurysm is growing, treatment may vary from watchful waiting to emergency surgery. Once an abdominal aortic aneurysm is found, doctors will closely monitor it so that surgery can be planned if it's necessary. Emergency surgery for a ruptured abdominal aortic aneurysm can be risky.
