Esophageal cancer samer kareem 1,771 Views • 2 years ago

Esophageal cancer is cancer that occurs in the esophagus — a long, hollow tube that runs from your throat to your stomach. Your esophagus carries food you swallow to your stomach to be digested. Esophageal cancer usually begins in the cells that line the inside of the esophagus. Esophageal cancer can occur anywhere along the esophagus, but in people in the United States, it occurs most often in the lower portion of the esophagus. More men than women get esophageal cancer. Esophageal cancer isn't common in the United States. In other areas of the world, such as Asia and parts of Africa, esophageal cancer is much more common.

Deep vein thrombosis (DVT) occurs when a blood clot (thrombus) forms in one or more of the deep veins in your body, usually in your legs. Deep vein thrombosis can cause leg pain or swelling, but may occur without any symptoms. Deep vein thrombosis can develop if you have certain medical conditions that affect how your blood clots. Deep vein thrombosis can also happen if you don't move for a long time, such as after surgery, following an accident, or when you are confined to a hospital or nursing home bed.

What Is A Gastric Ulcer? samer kareem 2,360 Views • 2 years ago

What Causes Ulcers? No single cause has been found for ulcers. However, it is now clear that an ulcer is the end result of an imbalance between digestive fluids in the stomach and duodenum. Most ulcers are caused by an infection with a type of bacteria called Helicobacter pylori (H. pylori). Factors that can increase your risk for ulcers include: Use of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, naproxen (Aleve, Anaprox, Naprosyn, and others), ibuprofen (Motrin, Advil, some types of Midol, and others), and many others available by prescription; even safety-coated aspirin and aspirin in powered form can frequently cause ulcers. Excess acid production from gastrinomas, tumors of the acid producing cells of the stomach that increases acid output (seen in Zollinger-Ellison syndrome) Excessive drinking of alcohol Smoking or chewing tobacco Serious illness Radiation treatment to the area What Are the Symptoms of an Ulcer? An ulcer may or may not have symptoms. When symptoms occur, they may include: A gnawing or burning pain in the middle or upper stomach between meals or at night Bloating Heartburn Nausea or vomiting In severe cases, symptoms can include: Dark or black stool (due to bleeding) Vomiting blood (that can look like "coffee-grounds") Weight loss Severe pain in the mid to upper abdomen

Surgical Options for Epilepsy
Surgical Options for Epilepsy samer kareem 1,313 Views • 2 years ago

Surgery is an elective procedure done in people who have had extensive testing to decide if they are potential candidates. The following criteria are considered when determining if a person may be a good candidate for surgery. Person has failed adequate trials of two first-line seizure medicines (ones that are commonly effective in controlling the type of seizures the person is experiencing) and one combination of at least two drugs. A trial of a medication is considered adequate when it has been increased gradually to the maximum dosage that does not cause serious side effects. If the person has frequent seizures, any improvement will be obvious after a short time. If the seizures generally occur far apart, however, it may take months to determine whether a medication is helping. At some epilepsy centers, patients are offered additional conventional or experimental medications before surgery is considered. But research suggests that each time a trial of medication fails to control a person's seizures, it becomes less likely that a different medicine or combination will be successful. Since uncontrolled seizures present serious physical risks and social and psychological consequences, the trend these days is to proceed with surgery much sooner than in the past if it seems appropriate for that person.

Patent ductus arteriosus (PDA)
Patent ductus arteriosus (PDA) samer kareem 1,830 Views • 2 years ago

Patent ductus arteriosus (PDA) is a persistent opening between two major blood vessels leading from the heart. The opening, called the ductus arteriosus, is a normal part of a baby's circulatory system before birth that usually closes shortly after birth. If it remains open, however, it's called a patent ductus arteriosus. A small patent ductus arteriosus often doesn't cause problems and might never need treatment. However, a large patent ductus arteriosus left untreated can allow poorly oxygenated blood to flow in the wrong direction, weakening the heart muscle and causing heart failure and other complications. Treatment options for a patent ductus arteriosus include monitoring, medications and closure by cardiac catheterization or surgery.

Among common cancers, pancreatic cancer has one of the poorest prognoses. Because pancreatic cancer often grows and spreads long before it causes any symptoms, only about 6% of patients are still alive five years after diagnosis. For some pancreatic patients, however, a complex surgery known as the Whipple procedure may extend life and could be a potential cure. Those who undergo a successful Whipple procedure may have a five-year survival rate of up to 25%.

Calcium Channel Blockers
Calcium Channel Blockers samer kareem 1,472 Views • 2 years ago

Calcium channel blockers prevent calcium from entering cells of the heart and blood vessel walls, resulting in lower blood pressure. Calcium channel blockers, also called calcium antagonists, relax and widen blood vessels by affecting the muscle cells in the arterial walls. Some calcium channel blockers have the added benefit of slowing your heart rate, which can further reduce blood pressure, relieve chest pain (angina) and control an irregular heartbeat. Examples of calcium channel blockers Some calcium channel blockers are available in short-acting and long-acting forms. Short-acting medications work quickly, but their effects last only a few hours. Long-acting medications are slowly released to provide a longer lasting effect. Several calcium channel blockers are available. Which one is best for you depends on your health and the condition being treated. Examples of calcium channel blockers include: Amlodipine (Norvasc) Diltiazem (Cardizem, Tiazac, others) Felodipine Isradipine Nicardipine Nifedipine (Adalat CC, Afeditab CR, Procardia) Nisoldipine (Sular) Verapamil (Calan, Verelan) In some cases, your doctor might prescribe a calcium channel blocker with other high blood pressure medications or with cholesterol-lowering drugs such as statins.
