Dialysis - A method of removing toxic substances (impurities or wastes) from the blood when the kidneys are unable to do so. Dialysis is most frequently used for patients who have kidney failure, but may also be used to quickly remove drugs or poisons in acute situations. This technique can be life saving in people with acute or chronic kidney failure.

Diverticulitis - Overview presented by the Mayo Clinic. Occurs when one or more diverticula in your digestive tract become inflamed or infected.

Division of AIDS (DAIDS) NIAID - Formed in 1986 to address U.S. research needs created by the advent and spread of the HIV/AIDS epidemic. The Division's mission is to increase basic knowledge of the pathogenesis, natural history, and transmission of HIV disease and to support research that promotes progress in its detection, treatment, and prevention.
Fracture of the Thoracic and Lumbar Spine - Fracture of one or more bones of the spinal column (vertebrae) of the middle (thoracic) or lower (lumbar) back is a serious injury. It is usually caused by high-energy trauma such as a car crash, fall, sports accident, or violent act (for example, a gunshot wound). People with osteoporosis, tumors, or other underlying conditions that weaken bone can get a spinal fracture with minimal trauma or normal activities of daily living.
Gas - When people complain of gas, they usually mean one or more of the following: Frequent belching of air from the stomach, bloating of the abdomen after eating, or frequent passing of gas from the rectum. It may be uncomfortable or inconvenient, but only rarely is gas associated with a serious illness. Gas is usually just the result of certain habits or diet choices. It occurs in one of two ways: as a result of swallowed air, or it is produced in the intestinal tract. Reclining after eating, inactivity, and stress may contribute to the problem. If the physician suspects gas is the result of some other illness, tests will be ordered to diagnose the problem.
Gastrointestinal Bleeding - A common clinical problem frequently requiring hospitalization. It can vary in degrees, from massive life threatening hemorrhage to a slow, insidious chronic blood loss. The overall mortality for severe GI bleeding is approximately 8 percent, but this number is diminishing with the arrival of superior diagnostic techniques and newer medical treatments. Many bleeding episodes resolve on their own, but it is still imperative that the bleeding site be determined. An exact diagnosis may prevent a recurrence of bleeding and may help us treat future episodes more effectively.
GeneTests - A clinical information resource relating genetic testing to the diagnosis, management, and genetic counseling of individuals and families with specific inherited disorders.
Guillain-Barre Syndrome (GBS) - GBS is a disorder in which the body's immune system attacks part of the peripheral nervous system. The first symptoms of this disorder include varying degrees of weakness or tingling sensations in the legs. In many instances, the weakness and abnormal sensations spread to the arms and upper body. These symptoms can increase in intensity until the muscles cannot be used at all and the person is almost totally paralyzed. In these cases, the disorder is life-threatening and is considered a medical emergency. The individual is often put on a ventilator to assist with breathing. Most individuals, however, have good recovery from even the most severe cases of GBS, although some continue to have some degree of weakness.

Hashimoto's Disease - A disorder that affects your thyroid, a small gland located at the base of your neck, below your Adam's apple. The thyroid gland is part of your endocrine system, which produces hormones that coordinate many of your body's activities. In Hashimoto's disease, also known as chronic lymphocytic thyroiditis, your immune system attacks your thyroid gland. The resulting inflammation often leads to an underactive thyroid gland (hypothyroidism). Hashimoto's disease is the most common cause of hypothyroidism in the United States.

HIV (Wikipedia) - Human immunodeficiency virus (HIV) is a retrovirus that can lead to acquired immunodeficiency syndrome (AIDS), a condition in humans in which the immune system begins to fail, leading to life-threatening opportunistic infections. Previous names for the virus include human T-lymphotropic virus-III (HTLV-III), lymphadenopathy-associated virus (LAV), and AIDS-associated retrovirus (ARV).Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells. The four major routes of transmission are unprotected sexual intercourse, contaminated needles, breast milk, and transmission from an infected mother to her baby at birth. Screening of blood products for HIV has largely eliminated transmission through blood transfusions or infected blood products in the developed world.
