Single-gene (also called Mendelian or monogenic) - This type is caused by changes or mutations that occur in the DNA sequence of one gene. Genes code for proteins, the molecules that carry out most of the work, perform most life functions, and even make up the majority of cellular structures. When a gene is mutated so that its protein product can no longer carry out its normal function, a disorder can result.

Constipation occurs commonly in children, affecting up to 10% at any given time. Still, only 3% of parents actually seek advice from the doctor for this condition. Constipation describes the infrequent passage of stools (bowel movements) or the passage of hard stools. Any definition of constipation depends upon comparison to how often the child normally passes stools and to the normal consistency of his or her stools.

Kaposi sarcoma is a cancer that causes lesions (abnormal tissue) to grow under the skin, in the lining of the mouth, nose, and throat, or in other organs. The lesions are usually purple and are made of cancer cells, new blood vessels, and white blood cells. Kaposi sarcoma is different from other cancers in that lesions may begin in more than one place in the body at the same time.

Diabetes means your blood glucose, or blood sugar, is too high. With Type 1 diabetes, your pancreas does not make insulin. Insulin is a hormone that helps glucose get into your cells to give them energy. Without insulin, too much glucose stays in your blood. Over time, high blood glucose can lead to serious problems with your heart, eyes, kidneys, nerves, and gums and teeth. There are two main types of diabetes: juvenile-onset and mature-onset.

Kaposi sarcoma presents as red to purplish spots (macules) and raised bumps (papules and nodules). They are generally first seen on the skin, commonly on legs or feet. They also occur in the mouth. Initially, the lesions are small and painless but they can ulcerate and become painful. Their visible presence may cause considerable anxiety. Kaposi sarcoma lesions can also occur internally; in the gut, lungs, genitals and lymphatic system.

You have to wait until the blood is reabsorbed, and that takes time. The capillaries must heal. You can put ice on it for the first 24 hours to reduce swelling, and them warm to help healing. 10 min. on 10 min off, for both cold and warm. Sorry, no way to get rid of it in 24 hours. If it is so important get one of those cover up make-ups.

Healthy people may develop bruises from any injury that doesn't break through the skin. Vigorous exercise may also cause bruises due to bringing about small tears in blood vessels walls. In a condition known as purpura simplex, there is a tendency to bruise easily due to an increased fragility of the blood vessels.

A bruise gets its deep color from a blood vessel or vessels that break under the skin and leak blood into the surrounding area. As it heals, it becomes paler in color and less painful to the touch. Depending on how many vessels were broken, bruises can be the size of a pencil eraser or 6 or more inches across. A black eye is also bruise-if there is no accompanying eye damage or nose breakage, it can be treated just like any other bruise.

Gallstones are stones that form in the gall (bile). Bile is a watery liquid made by the cells of the liver that is important for digesting food in the intestine, particularly fat. Liver cells secrete the bile they make into small canals within the liver. The bile flows through the canals and into larger collecting ducts within the liver (the intrahepatic bile ducts).
