GLOSSARY
Acute: An illness or symptom of sudden onset, which generally has a short duration.
AIDS: Acquired Immune Deficiency Syndrome. An immune system deficiency disorder that suddenly alters the body's ability to defend itself. The AIDS virus invades the T4 helper/inducer lymphocytes and multiplies, causing a breakdown in the body's immune system, eventually leading to overwhelming infection and/or cancer, with ultimate death.
Anemia: A condition resulting from an unusually low number of red blood cells or too little hemoglobin in the red blood cells. The most common type is iron-deficiency anemia in which the red blood cells are reduced in size and number, and hemoglobin levels are low. Clinical symptoms include shortness of breath, lethargy and heart palpitations.
Aneurysm: Localized enlargement of an artery.
Antibody: A type of serum protein (globulin) synthesized by white blood cells of the lymphoid type in response to an antigenic (foreign substance) stimulus. Antibodies are complex substances formed to neutralize or destroy these antigens in the blood. Antibody activity normally fights infection but can be damaging in allergies and a group of diseases that are called autoimmune diseases.
Apnea: Cessation of breathing.
Asthma: A lung disorder marked by attacks of breathing difficulty, wheezing, coughing, and thick mucus coming from the lungs. The episodes may be triggered by breathing foreign substances (allergens) or pollutants, infection, vigorous exercise, or emotional stress.
Atherosclerosis: Common form of arteriosclerosis associated with the formation of atheromas which are deposits of yellow plaques containing cholesterol, lipids, and lipophages within the intima and inner media of arteries. This results in a narrowing of the arteries, which reduces the blood and oxygen flow to the heart and brain as well as to other parts of the body and can lead to a heart attack, stroke, or loss of function or gangrene of other tissues.
Bacteria: Microscopic germs. Some bacteria are "harmful" and can cause disease, while other "friendly" bacteria protect the body from harmful invading organisms.
Benign: Literally: innocent; not malignant. Often used to refer to cells that are not cancerous.
Bronchitis: Inflammation of the mucous membrane of the bronchial tubes, frequently accompanied by cough, hypersecretion of mucus, and expectoration of sputum. Acute bronchitis is usually caused by an infectious agent and of short duration. Chronic bronchitis, generally the result of smoking, may also be known as Chronic Obstructive Pulmonary Disease (COPD) or Emphysema.
Cancer: Refers to the various types of malignant neoplasms that contain cells growing out of control and invading adjacent tissues, which may metastasize to distant tissues.
Candidiasis: Infection of the skin or mucous membrane with any species of candida, usually Candida albicans. The infection is usually localized to the skin, nails, mouth, vagina, bronchi, or lungs, but may invade the bloodstream. It is a common inhabitant of the GI tract, only becoming a problem when it multiplies excessively and invades local tissues. Growth is encouraged by a weakened immune system, as in AIDS, or with the prolonged administration of antibiotics. Vaginal symptoms include itching in the genital area, pain when urinating, and a thick odorless vaginal discharge.
Cardiovascular: Pertaining to the heart and blood vessels.
Chlamydia: A sexually-transmitted disease that is often without symptoms. Some females experience a white vaginal discharge that resembles cottage cheese, a burning sensation when urinating, itching, and painful intercourse. A clear watery urethral discharge in the male probably is a chlamydia infection.
Chronic: Usually Chronic illness: Illness extending over a long period of time.
Chronic Renal Failure: (CRF) Irreversible, progressive impaired kidney function. The early stage, when the kidneys no longer function properly but do not yet require dialysis, is known as Chronic Renal Insufficiency (CRI). CRI can be difficult to diagnose, as symptoms are not usually apparent until kidney disease has progressed significantly. Common symptoms include a frequent need to urinate and swelling, as well as possible anemia, fatigue, weakness, headaches and loss of appetite. As the disease progresses, other symptoms such as nausea, vomiting, bad breath and itchy skin may develop as toxic metabolites, normally filtered out of the blood by the kidneys, build up to harmful levels. Over time (up to 10 or 20 years), CRF generally progresses from CRI to End-Stage Renal Disease (ESRD, also known as Kidney Failure). Patients with ESRD no longer have kidney function adequate to sustain life and require dialysis or kidney transplantation. Without proper treatment, ESRD is fatal.
Cysts: A closed pocket or pouch of tissue; a cyst may form within any tissue in the body and can be filled with air, fluid, pus, or other material. Cysts within the lung generally are air filled, while cysts involving the lymph system or kidneys are fluid filled. Cysts under the skin are benign, extremely common, movable lumps. These may develop as a result of infection, clogging of sebaceous glands, developmental abnormalities or around foreign bodies.
Cytomegalovirus: (CMV): A member of the herpes virus family which may induce the immune-deficient state or cause active illness, such as pneumonia, in a patient already immune-deficient due to chronic illness, such as cancer or organ transplantation therapy.
Epstein Barr virus: (EBV): A virus that causes infectious mononucleosis and that is possibly capable of causing other diseases in immunocompromised hosts.
Gonorrhea: A sexually-transmitted disease that is often without symptoms. If there are symptoms in the female, they include frequent and painful urination, cloudy vaginal discharge, vaginal itching, inflammation of the pelvic area, and abnormal uterine bleeding. If the male has a purulent (pus-like) urethral discharge, he should assume he has gonorrhea until proven otherwise.
HIV: Abbreviation for human immunodeficiency virus, a retrovirus associated with onset of advanced immunodeficiency syndrome (AIDS).
Immune System: A complex that protects the body from disease organisms and other foreign bodies. The system includes the humoral immune response and the cell-mediated response. The immune system also protects the body from invasion by making local barriers and inflammation.
Interstitial Cystitis: A chronic bladder problem involving a bladder wall that is inflamed and irritated. Symptoms include an urgent need to urinate, both daytime and nighttime; pressure, pain and tenderness around the bladder, pelvis and perineum (the area between the anus and vagina or the anus and scrotum) which may increase as the bladder fills and decrease as it empties during urination; a bladder that won't hold as much urine as it did before; pain during sexual intercourse; in men, discomfort or pain in the penis or scrotum. In many women, the symptoms get worse before their menstrual period. Stress may also make the symptoms worse, but it does not cause them.
Kidney Stone: A stone (concretion) in the kidney. If the stone is large enough to block the tube (ureter) and stop the flow of urine from the kidney, it must be removed by surgery or other methods. Also called Renal Calculus. Symptoms usually begin with intense waves of pain as a stone moves in the urinary tract. Typically, a person feels a sharp, cramping pain in the back and side in the area of the kidney or in the lower abdomen. Sometimes nausea and vomiting occur. Later, pain may spread to the groin. The pain may continue if the stone is too large to pass; blood may appear in the urine and there may be the need to urinate more often or a burning sensation during urination. If fever and chills accompany any of these symptoms, an infection may be present and a doctor should be seen immediately.
Multiple Sclerosis: Demyelinating disorder of the central nervous system, causing patches of sclerosis (plaques) in the brain and spinal cord, manifested by loss of normal neurological functions, e.g., muscle weakness, loss of vision, and mood alterations.
Perineum: The area between the anus and the posterior part of the external genitalia.
Phlebitis: Inflammation of a vein. Symptoms of superficial phlebitis include pain, swelling, redness, and warmth around the affected vein. The vein feels hard to the touch because of the clotted blood.
Prostate: The prostate gland in men that surrounds the neck of the bladder and the urethra and produces a secretion that liquefies coagulated semen.
Raynaud's Phenomenon: Raynaud's disease or syndrome is a disorder of blood circulation, mainly in the fingers and toes. It is of unknown cause and characterized by changes of the skin that are aggravated by exposure to cold: first, becoming white with numbness and pain as a result of inadequate oxygenation of the blood, then red/purple with a burning sensation. The sudden constriction of blood vessels causes decreased blood flow to the extremities and can, in extreme cases, lead to gangrene. Also called "white finger", "wax finger" or "dead finger".
Shingles: A severe infection caused by the Varicella-Zoster virus (VZV), affecting mainly adults. It causes painful skin blisters that follow the underlying route of brain or spinal nerves infected by the virus. Also know as herpes zoster.
Stroke: A sudden loss of brain function caused by a blockage or rupture of a blood vessel that supplies the brain, characterized by loss of muscular control, complete or partial loss of sensation or consciousness, dizziness, slurred speech, or other symptoms that vary with the extent and severity of the damage to the brain. The most common manifestation is some degree of paralysis, but small strokes may occur without symptoms. Usually caused by arteriosclerosis, it often results in brain damage.
Thrombophlebitis: Venous inflammation with formation of clots. It can occur without any symptoms until the clot reaches the lungs. However, in about half of cases, there are warning symptoms including swelling, pain and warmth in the entire calf, ankle, foot, or thigh (depending on where the involved vein is located).
Thyroid: Thyroid Gland: An organ with many veins. It is at the front of the neck. It is essential to normal body growth in infancy and childhood. It releases thyroid hormones - iodine-containing compounds that increase the rate of metabolism, affect body temperature, regulate protein, fat, and carbohydrate catabolism in all cells. They keep up growth hormone release, skeletal maturation, and heart rate, force, and output. They promote central nervous system growth, stimulate the making of many enzymes, and are necessary for muscle tone and vigor.
Tuberculosis: Also known as TB, Consumption or "The White Plague", tuberculosis is an infectious disease caused by a bacterium called Mycobacterium tuberculosis, usually affecting the lungs but possibly also the brain, kidneys and bones. Patients may at first be symptom-free or experience a flu-like illness. In the secondary stage, there might be a slight fever, night sweats, weight loss, fatigue and various other symptoms, depending on the part of the body affected. Tuberculosis of the lung is usually associated with a dry cough that eventually leads to a productive cough with blood-stained sputum. There might also be chest pain and shortness of breath.
Urethral Discharge: A discharge from the urethra (the narrow tube that transports urine from the bladder to the outside of the body) that may be a cloudy, yellow-green mucous, white (like 'cottage cheese'), either watery or thick, odorless or malodorous.
Varicose Veins: Twisted, widened veins with incompetent valves.
Vasculitis: Inflammation and necrosis of blood vessels, including arteries, veins and capillaries. The damage may be due to infectious agents, mechanical trauma, radiation or toxins; often no specific causative factor is identified. It involves immune mechanisms such as deposition of circulating immune complexes and direct attack by circulating antibodies
Virus: Any of a vast group of minute structures composed of a protein coat and a core of DNA and/or RNA that reproduces in the cells of the infected host. Capable of infecting all animals and plants, causing devastating disease in immunocompromised individuals. Viruses are not affected by antibiotics, and are completely dependent upon the cells of the infected host for the ability to reproduce.
Yeast: A single-cell organism that may cause infection in the mouth, vagina, gastrointestinal tract, and any or all bodily parts. Common yeast infections include candidiasis and thrush.
