Angina, stroke and other vascular conditions are often caused by atherosclerosis ('arteriosclerosis') and treated by stenting, where doctors open up a blocked artery in the heart by inserting a sliver of metal into the artery to keep it open. However, there are allegations that far too many stents are being put in when medications and lifestyle changes could do the job just as well if not better.

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.

Hepatitis D, also known as the delta virus, is an infection that causes the liver to become inflamed. This swelling can impair liver function and cause long-term liver problems, including liver scarring and cancer. The condition is caused by the hepatitis D virus (HDV). This virus is rare in the United States, but it’s fairly common in the following regions: South America West Africa Russia Pacific islands Central Asia the Mediterranean

A pulmonary embolism (PE) usually happens when a blood clot called a deep vein thrombosis (DVT), often in your leg, travels to your lungs and blocks a blood vessel. That leads to low oxygen levels in your blood. It can damage the lung and other organs and cause heart failure, too. A PE can be life-threatening, so if you've been diagnosed with DVT, you should be aware of this risk. Follow the treatment plan for your DVT to stop the clot from getting bigger and to keep new clots from forming. Symptoms and Diagnosis PE won't always cause symptoms. You might have: Chest pain, which may get worse with a deep breath Sudden shortness of breath or rapid breathing Fast heartbeat Sudden cough Coughing up blood Lightheadedness or fainting Anxiety Call 911 if you notice these symptoms. They could also be symptoms of a heart attack, pneumonia, or other serious problems.

Eye cancers can be primary (starts within the eye) and metastatic cancer (spread to the eye from another organ). The two most common cancers that spread to the eye from another organ are breast cancer and lung cancer. Other less common sites of origin include the prostate, kidney, thyroid, skin, colon and blood or bone marrow. Melanomas (choroidal, ciliary body and uveal) -Early stages has no symptoms (the person does not know there is a tumor until an ophthalmology examination). As the tumor grows, symptoms can be blurred vision, decreased vision, double vision, eventual vision loss and if they continue to grow the tumor can break past the retina causing retinal detachment.

A small spontaneous pneumothorax may resolve without treatment; a pneumothorax arising as a result of lung disease or injury requires immediate treatment. Treatment may include insertion of a chest tube or aspiration of the free air in the chest cavity.

Bacterial abscess of the liver is relatively rare; however, it has been described since the time of Hippocrates (400 BCE), with the first published review by Bright appearing in 1936. In 1938, Ochsner's classic review heralded surgical drainage as the definitive therapy; however, despite the more aggressive approach to treatment, the mortality remained at 60-80%. [1] The development of new radiologic techniques, the improvement in microbiologic identification, and the advancement of drainage techniques, as well as improved supportive care, have reduced mortality to 5-30%; yet, the prevalence of liver abscess has remained relatively unchanged. Untreated, this infection remains uniformly fatal.

Hiatal hernias occur when contents of the abdominal cavity protrude through the esophageal hiatus of the diaphragm. Factors that contribute to the development of a hiatal hernia include an enlargement of the esophageal hiatus due to developmental defects, an increased abdominal thoracic pressure gradient, and the depletion of elastic fibers in the phrenoesophageal membrane with aging. There are four different types of hiatal hernias and management varies depending on the type. Type I, also known as a sliding hernia, is a simple displacement of the gastroesophageal junction into the thoracic cavity. The stomach remains in the abdominal cavity. This is the most common type of hiatal hernia, accounting for about 95% of all hiatal hernias. Types II-IV are classified as paraesophageal hernias. Type II occurs when the gastroesophageal junction maintains its position but the gastric fundus herniates through the diaphragmatic hiatus. Type III has both the gastroesophageal junction and the stomach herniate above the diaphragm. When more than 30% of the stomach is herniated into the thoracic cavity, it is termed a “giant” paraesophageal hernia. A patient has a type IV hernia when other organs, such as the colon, in addition to the stomach herniate above the diaphragm.

Mitosis, a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.

Craniectomy is neurosurgical procedure that involves removing a portion of the skull in order to relieve pressure on the underlying brain. This procedure is typically done in cases where a patient has experienced a very severe brain injury that involves significant amounts of bleeding around the brain or excessive swelling of the brain.

During open-heart valve surgery, the doctor makes a large incision in the chest. Blood is circulated outside of the body through a machine to add oxygen to it (cardiopulmonary bypass or heart-lung machine). The heart may be cooled to slow or stop the heartbeat so that the heart is protected from damage while surgery is done to replace the valve with an artificial valve. The artificial valve might be mechanical (made of man-made substances). Others are made out of animal tissue, often from a pig.

the elbow is the second most frequently dislocated major joint, after the shoulder. It is the most commonly dislocated joint in children. [1] More than 90% of all elbow dislocations are posterior dislocations. This injury entails disengagement of the coronoid process of the ulna from the trochlea of the humerus with movement posteriorly. [2] The mechanism of injury is typically a fall onto an outstretched hand (FOOSH) with the elbow in extension upon impact.
