PREVIOUS AND NEXT TERMS--------------------------------------
Acanthamoeba
A microscopic organism, an amoeba, found in soil, dust and fresh water (lakes, rivers, hot springs and hot tubs). Acanthamoeba also occur in brackish water and sea water as well as in heating, venting, and air conditioner units, humidifiers, and dialysis units. Acanthamoeba can enter the skin through a cut, wound, or through the nostrils and, once inside the body, can travel to the lungs and through the bloodstream to other parts of the body, especially to the central nervous system (the brain and spinal cord). Through improper storage, handling, and disinfection of contact lenses, Acanthamoeba can enter the eye and there cause infection. A particularly dire infection caused by Acanthamoeba called granulomatous amebic encephalitis is characterized by headache, stiff neck, nausea, vomiting, confusion, loss of balance, seizures, and coma that can progress over several weeks and end in death. Acanthamoeba infections occur more frequently in people with compromised immune systems and the chronically ill. Eye and skin infections are generally treatable while infections of the brain are almost always fatal.
Acanthamoeba keratitis
Infection of the cornea by acanthamoeba, a microscopic water-borne ameba. The disease tends to occur in people who wear contact lens. It can accompany a bacterial infection of the eye. Acanthamoeba keratitis can produce corneal ulceration and result in severe loss of vision and even blindness. Signs and symptoms are persistent redness and pain in the eye. Treatment is with multiple antibiotics, often including antifungal drugs, and sometimes surgery after the infection has subsided.
Acanthosis nigricans
"A skin condition characterized by dark thickened velvety patches, especially in the folds of skin in the axilla (armpit), groin and back of the neck. The condition is complex. It can occur with endocrine diseases such as Cushing disease, tumors of the pituitary, and diabetes mellitus. It is common in people who have insulin resistance -- whose body is not responding correctly to the insulin that they make in their pancreas. Acanthosis nigricans also occurs with underlying malignancies (especially carcinomas of the vicera), administration of certain drugs, and as a genetic disorder inherited in an autosomal dominant manner.
Acapnia
"Less than the normal level of carbon dioxide in the blood. The opposite of hypercapnia. The origin of the word ""acapnia"" is curious. It comes from the Greek ""a-"" meaning ""without"" + ""kapnos"" meaning ""smoke"" so acapnia literally means ""smokeless"" referring to carbon dioxide which is a principal part of smoke.
Acaricide
ACC
Adenoid cystic carcinoma.
Accelerated phase of leukemia
Refers to chronic myelogenous leukemia (CML) that is progressing. The number of immature, abnormal white blood cells in the bone marrow and blood is higher than in the chronic phase but not as high as in the blast phase.
Acceptable daily intake
Estimate of the amount of a substance in food or drinking water, expressed on a body mass basis (usually mg/kg body weight), which can be ingested daily over a lifetime by humans without appreciable health risk. For calculation of the daily intake per person, a standard body mass of 60 kg is used. The acceptable daily intake is normally used for food additives (tolerable daily intake is used for contaminants). Abbreviated ADI.
Access
1. In general, a means of approaching something. 2. In health care, the opportunity or right to receive health care. 3. In dialysis, the point on the body where a needle or catheter is inserted to gain entry to the bloodstream.
