ABR test: Auditory brainstem response test. An automated test for hearing and brain (neurological) functioning that is performed by applying wires to the skin around the ear. ABR may be used in the evaluation of:
Hearing integrity (and neurologic normalcy) in infants and young children.
Neurologic integrity (and hearing) in patients who are comatose, unresponsive, or impaired due to a stroke, an acoustic neuroma (tumor on the hearing nerve), Ménière’s disease, etc.
The ABR test involves attaching electrodes to the head to record electrical activity from the auditory nerve (the hearing nerve) and other parts of the brain. Also known as brainstem auditory evoked potentials (BAEP).
- Abruptio (abruptio placentae)
Abruptio (abruptio placentae): Premature separation of the placenta from the wall of the uterus. Abruption is a potentially serious problem both for the mother and baby.
Abrasion: An abrasion or “excoriation” is a wearing away of the upper layer of skin as a result of applied friction force. In dentistry an “abrasion” is the wearing away of the tooth substance.
- Abscess, breast
Abscess, breast: See: Breast abscess. see also: Breast infection; Mastitis.
Abruption: A sudden breaking off or away. Abruption of the placenta (abruptio placentae) is the premature separation of the placenta from the wall of the uterus, a potentially very serious situation for the mother and baby.
- Abscess, peritonsillar
Abscess, peritonsillar: An abscess behind the tonsils that pushes one of the tonsils toward the uvula (the prominent soft tissue dangling from the back of the palate in the back of the mouth). A peritonsillar abscess is generally very painful and associated with difficulty opening the mouth. If a peritonsillar abscess is untreated, the infection […]
