AHD"Abbreviation for alveolar hydatid disease; American Hospital Directory; and atherosclerotic heart disease."
RELATED TERMS--------------------------------------
Alveolar
"Pertaining to the alveoli, the tiny air sacs in the lungs. The exchange of oxygen and carbon dioxide takes place in the alveoli which look like cells in a honeycomb. The word comes from the Latin diminutive of ""alveus"" meaning a cavity or hollow = a little cavity or hollow."
Hydatid
A cyst containing watery fluid and the larvae of certain tapeworms.
Disease
Illness or sickness often characterized by typical patient problems (symptoms) and physical findings (signs). Disruption sequence: The events that occur when a fetus that is developing normally is subjected to a destructive agent such as the rubella (German measles) virus.
Atherosclerotic
Pertaining to atherosclerosis, the process of progressive thickening and hardening of the walls of arteries from fat deposits on their inner lining.
Heart
The hollow, muscular organ responsible for pumping blood through the circulatory system.

Agreement, arbitration
See: Arbitration agreement.
Ague
A fever (such as from malaria) that is marked by paroxysms of chills, fever, and sweating recurring regular intervals. Also a fit of shivering, a chill. Hence, ague can refer to both chills and fevers.
AGXT
A gene that provides instructions for making a liver enzyme called alanine-glyoxylate aminotransferase (AGXT). Inside liver cells, this enzyme is found in peroxisomes, structures that contain many different enzymes used to produce energy and the basic materials important for cellular activities. AGXT converts a compound called glyoxylate to glycine, an amino acid that is a building block for making enzymes and other proteins.
Agyrophobia
"Abnormal and persistent fear of crossing streets, highways and other thoroughfares; fear of thoroughfares themselves. Sufferers experience anxiety even though they realize that streets, highways and other thoroughfares pose no threat commensurate with their fear."
AHC
Alternating hemiplegia of childhood.
AHD
Aicardi syndrome
A genetic disorder characterized by the partial or complete agenesis of the corpus callosum (the structure that links the 2 hemispheres of the brain), infantile spasms (a characteristic form of childhood seizures), mental retardation, and an ocular (eye) abnormality called chorioretinal lacunae in which there are lacunae (holes) in the retina of the eye.
Aid, vibrotactile
See: Vibrotactile aid.
AIDS dementia complex
A brain disorder that occurs in people with AIDS that causes the loss of cognitive capacity, affecting the ability to function in a social or occupational setting. The exact mechanism by which HIV triggers the AIDS dementia complex has not been determined, but it may result from HIV infection of cells in the brain or from an inflammatory reaction to such an infection. The AIDS dementia complex is an AIDS-defining illness: one of the serious illnesses that occurs in HIV-positive individuals and a reason for an AIDS diagnosis according to the definition of AIDS by the CDC (Centers for Disease Control & Prevention).
AIDS wasting syndrome
The involuntary weight loss of 10% of baseline body weight plus either chronic diarrhea (two loose stools per day for more than 30 days) or chronic weakness and documented fever (for 30 days or more, intermittent or constant) in the absence of a concurrent illness or condition other than HIV infection that would explain the findings.
AIDS-related complex
A term used to describe people with HIV infection who have only mild symptoms of illness such as swollen lymph glands. The term is rarely used today.
