Non-alcoholic fatty liver disease (NAFLD) is a very common disorder and refers to a group of conditions where there is accumulation of excess fat in the liver of people who drink little or no alcohol. The most common form of NAFLD is a non serious condition called fatty liver.

A simple continuous stitch can be a useful technique for skin closure when speed is important, e.g. closing a scalp laceration on a screaming child. The simple running, or continuous suture, is begun in the same way as a simple interrupted suture.

What does the placenta do? The placenta is an organ that develops in your uterus during pregnancy. This structure provides oxygen and nutrients to your growing baby and removes waste products from your baby's blood. The placenta attaches to the wall of your uterus, and your baby's umbilical cord arises from it. In most pregnancies, the placenta attaches at the top or side of the uterus.

Artificial kidney is often a synonym for hemodialysis, but may also, more generally, refer to renal replacement therapies (with exclusion of kidney transplantation) that are in use and/or in development.

There's only one group of people who really know what happens when you die: the dead. And since the dead won't be revealing their secrets anytime soon, it's up to scientists to explain what happens when a person dies. Death, just like life, is a process, scientists say. The first stage of this process is known as clinical death. It lasts from four to six minutes, beginning when a person stops breathing and the heart stops pumping blood. During this time, there may be enough oxygen in the brain that no permanent brain damage occurs. Other organs, such as the kidneys and eyes, also remain alive throughout clinical death.

The spleen, a spongy, soft organ about as big as a person’s fist, is located in the upper left part of the abdomen, just under the rib cage. The splenic artery brings blood to the spleen from the heart. Blood leaves the spleen through the splenic vein, which drains into a larger vein (the portal vein) that carries the blood to the liver. The spleen has a covering of fibrous tissue (the splenic capsule) that supports its blood vessels and lymphatic vessels. The spleen is made up of two basic types of tissue, each with different functions: White pulp Red pulp The white pulp is part of the infection-fighting (immune) system. It produces white blood cells called lymphocytes, which in turn produce antibodies (specialized proteins that protect against invasion by foreign substances). The red pulp filters the blood, removing unwanted material. The red pulp contains other white blood cells called phagocytes that ingest microorganisms, such as bacteria, fungi, and viruses. It also monitors red blood cells, destroying those that are abnormal or too old or damaged to function properly. In addition, the red pulp serves as a reservoir for different elements of the blood, especially white blood cells and platelets (cell-like particles involved in clotting). However, releasing these elements is a minor function of the red pulp.

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.

What could cause a blockage in the stomach? Mechanical causes of intestinal obstruction may include: Adhesions or scar tissue that forms after surgery. Foreign bodies (objects that are swallowed and block the intestines) Gallstones (rare) Hernias. Impacted stool. Intussusception (telescoping of one segment of bowel into another) Tumors blocking the intestines. Less common radiologic signs are seen in specific circumstances. Most closed-loop obstructions (75%) are caused by adhesions. A closed-loop obstruction occurs when a loop of bowel is not decompressed by the caudal passage of gas and fluid.

Breast lumps facts Breast lumps can be caused by infections, injuries, non-cancerous growths, and cancer. Breast cancer usually causes no pain in the breast. The symptoms of breast cancer include painless breast lumps, nipple discharge, and inflammation of the skin of the breast. The chances that a particular breast lump could be cancerous depends on many factors, including past medical history, physical examination, as well as genetic and other risk factors. The only way to be certain that a lump is not cancerous is to have a tissue sampling (biopsy). There are several ways to do the biopsy. The treatment of a breast lump depends on its cause.

The lumps may be hard or rubbery and can appear as a single breast lump that may be large or small. Fibrocystic changes also can appear as thickening of the breast tissue. Fibrocystic changes can occur in one or both breasts and are the most common cause of benign breast lumps in women age 35 to 50.

Colonoscopy is a test that allows your doctor to look at the inner lining of your large intestine (rectum and colon). He or she uses a thin, flexible tube called a colonoscope to look at the colon. A colonoscopy helps find ulcers, colon polyps, tumors, and areas of inflammation or bleeding.

Parkinson's disease is a progressive disorder of the nervous system that affects movement. It develops gradually, sometimes starting with a barely noticeable tremor in just one hand. But while a tremor may be the most well-known sign of Parkinson's disease, the disorder also commonly causes stiffness or slowing of movement. In the early stages of Parkinson's disease, your face may show little or no expression, or your arms may not swing when you walk. Your speech may become soft or slurred. Parkinson's disease symptoms worsen as your condition progresses over time. Although Parkinson's disease can't be cured, medications may markedly improve your symptoms. In occasional cases, your doctor may suggest surgery to regulate certain regions of your brain and improve your symptoms.

Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins coming from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.

Rehydration Tips: Kids & Teens (Ages 1+) Give clear liquids (avoid milk and milk products) in small amounts every 15 minutes. ... If your child vomits, start over with a smaller amount of fluid (2 teaspoons, or about 10 milliliters) and continue as above. ... After no vomiting for about 8 hours, introduce solid foods slowly.

Although the Apgar score was developed in 1952 by an anesthesiologist named Virginia Apgar, you also might hear it referred to as an acronym for: Appearance, Pulse, Grimace, Activity, and Respiration. The Apgar test is usually given to a baby twice: once at 1 minute after birth, and again at 5 minutes after birth.

Osgood-Schlatter disease can cause a painful lump below the kneecap in children and adolescents experiencing growth spurts during puberty. Osgood-Schlatter disease occurs most often in children who participate in sports that involve running, jumping and swift changes of direction — such as soccer, basketball, figure skating and ballet. While Osgood-Schlatter disease is more common in boys, the gender gap is narrowing as more girls become involved with sports. Age ranges differ by sex because girls experience puberty earlier than do boys. Osgood-Schlatter disease typically occurs in boys ages 13 to 14 and girls ages 11 to 12. The condition usually resolves on its own, once the child's bones stop growing.

Marfan syndrome is a genetic disorder that affects the body’s connective tissue. Connective tissue holds all the body’s cells, organs and tissue together. It also plays an important role in helping the body grow and develop properly. marfan_general_2.jpg What is Marfan Syndrome?Connective tissue is made up of proteins. The protein that plays a role in Marfan syndrome is called fibrillin-1. Marfan syndrome is caused by a defect (or mutation) in the gene that tells the body how to make fibrillin-1. This mutation results in an increase in a protein called transforming growth factor beta, or TGF-β. The increase in TGF-β causes problems in connective tissues throughout the body, which in turn creates the features and medical problems associated with Marfan syndrome and some related disorders. Because connective tissue is found throughout the body, Marfan syndrome can affect many different parts of the body, as well. Features of the disorder are most often found in the heart, blood vessels, bones, joints, and eyes. Some Marfan features – for example, aortic enlargement (expansion of the main blood vessel that carries blood away from the heart to the rest of the body) – can be life-threatening. The lungs, skin and nervous system may also be affected. Marfan syndrome does not affect intelligence.
