This video: Pancreatic cancer begins in the tissues of your pancreas — an organ in your abdomen that lies horizontally behind the lower part of your stomach. Your pancreas secretes enzymes that aid digestion and hormones that help regulate the metabolism of sugars. Pancreatic cancer often has a poor prognosis, even when diagnosed early. Pancreatic cancer typically spreads rapidly and is seldom detected in its early stages, which is a major reason why it's a leading cause of cancer death. Signs and symptoms may not appear until pancreatic cancer is quite advanced and complete surgical removal isn't possible.
The exact cause of schizophrenia isn't known, but genetics, environment, and imbalanced brain chemicals may play a role. Schizophrenia is characterized by abnormal social behavior. In severe cases, patients may see or hear things that aren't real. Treatment is usually lifelong and often involves a combination of medications and psychological and social therapy.

Laryngectomy is the removal of the larynx and separation of the airway from the mouth, nose and esophagus. In a total laryngectomy the entire larynx is removed and in a partial laryngectomy only a portion is taken out. The laryngectomee breathes through an opening in the neck known as a stoma.
CD4 T-cells (a type of white blood cell) are important to your body's defence against infections. This animation describes how your immune system is weakened by the HIV virus, which targets CD4 T-cells and leads to their gradual decline in number. Low to very low levels of CD4 cells put you at risk for 'opportunistic infections' that take advantage of the body's weakened immune system.
Pancreatic cysts are saclike pockets of fluid on or in your pancreas, a large organ behind the stomach that produces hormones and enzymes that help digest food. Most pancreatic cysts aren't cancerous, and many don't cause symptoms. They're typically found during imaging testing for another problem. Some are actually noncancerous (benign) pockets of fluids lined with scar or inflammatory tissue, not the type of cells found in true cysts (pseudocysts). But some pancreatic cysts can be or can become cancerous. Your doctor might take a sample of the pancreatic cyst fluid to determine if cancer cells are present. Or your doctor might recommend monitoring a cyst over time for changes that indicate cancer.
After the nose surgery the patients are advised to keep their nose taped for 2 weeks to 2 months. During the first two weeks, the surgery tapes influence both swelling and forming. From the second week on however, the nose tapes are applied just to reduce the swelling.
Holoprosencephaly (HPE, once known as arhinencephaly) is a cephalic disorder in which the prosencephalon (the forebrain of the embryo) fails to develop into two hemispheres. Normally, the forebrain is formed and the face begins to develop in the fifth and sixth weeks of human pregnancy. The condition also occurs in other species, as with Cy, the Cyclops kitten.
Low potassium (hypokalemia) refers to a lower than normal potassium level in your bloodstream. Potassium is a chemical (electrolyte) that is critical to the proper functioning of nerve and muscles cells, particularly heart muscle cells. Normally, your blood potassium level is 3.6 to 5.2 millimoles per liter (mmol/L). A very low potassium level (less than 2.5 mmol/L) can be life-threatening and requires urgent medical attention.
SCOOP transtracheal oxygen is indicated for patients with chronic hypoxemia which persists in spite of optimal medical therapy. Arterial blood gases obtained while breathing room air should show a PaO2< 55 mm Hg. SCOOP transtracheal oxygen is also indicated for patients with a PaO2 of 56-59 mm Hg ...
if they also have: 1) dependent edema suggesting congestive heart failure, 2) "P" pulmonale on EKG (P wave greater than 3mm in standard leads II, III or AVF), or 3) erythrocythemia with a hematocrit of >55%.
