Cardiac arrest is the abrupt loss of heart function in a person who may or may not have diagnosed heart disease. The time and mode of death are unexpected.

Factitious disorder is the term used to describe a pattern of behavior centered on the exaggeration or outright falsifications of one’s own health problems or the health problems of others. Some people with this disorder fake or exaggerate physical problems; others fake or exaggerate psychological problems or a combination of physical and psychological problems. Factitious disorder differs from a pattern of falsified or exaggerated behavior called malingering. While malingerers make their claims out of a motivation for personal gain, people with factitious disorder have no such motivation.

Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems. Sometimes, however, one or more of the pouches become inflamed or infected. That condition is known as diverticulitis (die-vur-tik-yoo-LIE-tis). Diverticulitis can cause severe abdominal pain, fever, nausea and a marked change in your bowel habits. Mild diverticulitis can be treated with rest, changes in your diet and antibiotics. Severe or recurring diverticulitis may require surgery.

Liver transplantation is surgery to remove a diseased or injured liver and replace it with a healthy whole liver or a segment of a liver from another person, called a donor. People with either acute or chronic liver failure may need a liver transplant to survive.

Absence of a woman's monthly menstrual period is called amenorrhea. Secondary amenorrhea is when a woman who has been having normal menstrual cycles stops getting her periods for 6 months or longer. Causes Secondary amenorrhea can occur due to natural changes in the body. For example, the most common cause of secondary amenorrhea is pregnancy. Breastfeeding and menopause are also common, but natural, causes. Women who take birth control pills or who receive hormone shots such as Depo-Provera may not have any monthly bleeding. When they stop taking these hormones, their periods may not return for more than 6 months. You are more likely to have absent periods if you: Are obese Exercise too much and for long periods of time Have very low body fat (less than 15 to 17%) Have severe anxiety or emotional distress Lose a lot of weight suddenly (for example, from strict or extreme diets or after gastric bypass surgery) Other causes include: Brain (pituitary) tumors Drugs for cancer treatment Drugs to treat schizophrenia or psychosis Overactive thyroid gland Polycystic ovarian syndrome Reduced function of the ovaries

The shoulder joint is formed where the humerus (upper arm bone) fits into the scapula (shoulder blade), like a ball and socket.

A man's age matters. As men get older, the chances of conceiving and having a healthy child decline. Male fertility starts to decline after 40 when sperm quality decreases. This means it takes longer for their partners to conceive and when they do, there's an increased risk of miscarriage.

Hold your elbows at shoulder level and place the backs of your hands together with your wrists bent at 90 degrees. This position increases the pressure on the median nerve. If the test reproduces or worsens your symptoms (pain and tingling in your hands), you may have carpal tunnel syndrome.

Pancreatic Auto Islet Transplantation is a procedure used to maintain insulin production and secretion in patients with chronic pancreatitis that are undergoing a total pancreatectomy, or removal of the entire pancreas. When all other medical therapies fail to control the pain, removal of the pancreas may be an option; however it can leave a person diabetic, which means that the body can no longer control blood sugar levels, and will require intensive testing of blood sugar and injections of insulin. The pancreas is an organ, located in the upper abdominal cavity, behind the stomach, liver and colon. Within the pancreas, specialized clusters of cells known as islets produce insulin, which maintain healthy blood sugar levels. The pancreas also produces enzymes to help digest food. In order to alleviate pain and maintain insulin production, the pancreas is removed from the body, processed and the islets are harvested. Once the pancreas is removed, it is placed in a solution and put into a machine where the pancreas is digested. The islets are then infused into the patient’s liver. Within a short time, the islets are expected to start producing insulin. In 80% of patients, the pain from pancreatitis is relieved by a total pancreatectomy. Over time, some patients may be diabetic and will need to take insulin to maintain healthy blood sugar levels. All patients will take pancreatic enzymes to help digest food after surgery.

Your egg usually lives for just 12 to 24 hours, but sperm will live inside you for anything from a few hours to seven days, with one to three days the optimum time. ... But because a small number of sperm are long-living, having sex up to six days before ovulation can also result in pregnancy.

Spermatogenesis is the process in which spermatozoa are produced from spermatogonial stem cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.
