Rosacea
|
|
Rosacea An acneiform eruption occurring mostly in middle-aged adults and appearing generally on the forehead, cheeks, nose, and chin. Three types are recognized: granulomatous, glandular hyperplastic with rhinophyma, and ocular.
RELATED TERMS--------------------------------------
Eruption
Process of teeth protruding through the gums
Chin
Medically, the mentum. The lower portion of the face below the lower lip including the prominence of the lower jaw and the line of fusion of the two separate halves of the jawbone (mandible). This line of fusion (called the symphysis menti) encloses a triangular area at tip of the chin (termed the mental protuberance). On each side, below the second premolar tooth, is the mental foramen, an opening for the passage of blood vessels and a nerve that supply the chin.
Granulomatous
Composed of granulomas.
Ocular
Having to do with the eye.

Ruminant
A suborder of the order Artiodactyla whose members have the distinguishing feature of a four-chambered stomach. Horns or antlers are usually present, at least in males.
Ruminantia
A suborder of the order Artiodactyla whose members have the distinguishing feature of a four-chambered stomach. Horns or antlers are usually present, at least in males.
Rabies
An acute infectious disease of the central nervous system affecting almost all mammals, including humans. It is caused by a rhabdovirus and usually spread by contamination with virus-laden saliva of bites inflicted by rabid animals. Important animal vectors include the dog, cat, vampire bat, mongoose, skunk, wolf, raccoon, and fox.
Repetitive strain injury
Harmful and painful condition caused by overuse or overexertion of some part of the musculoskeletal system, often resulting from work-related physical activities. It is characterized by inflammation, pain, or dysfunction of the involved joints, bones, ligaments, and nerves.
Restless legs
A disorder characterized by aching or burning sensations in the lower and rarely the upper extremities that occur prior to sleep or may awaken the patient from sleep. Complying with an irresistible urge to move the affected limbs brings temporary relief. Sleep may become disrupted, resulting in excessive daytime hypersomnolence. This condition may be associated with uremia; diabetes; and rheumatoid arthritis. Restless Legs Syndrome differs from nocturnal myoclonus syndrome in that in the lattercondition the individual does not report adverse sensory stimuli and it is primarly a sleep-associated movement disorder.
Rosacea
Radioallergosorbent test (RAST)
A solid-phase radioimmunoassay for detecting IgE antibody specific for a particular allergen.
Radioimmunoassay (RIA)
A widely used technique for measurement of primary antigen-antibody interactions, and for the determination of the level of important biological substances in mixed samples. It takes advantage of the specificity of the antigen-antibody interaction and the sensitivity that derives from measurement of radioactively labelled materials.
Reagin
Allergist's term for IgE antibodies.
Respiratory burst
Oxygen dependent increase in metabolic activity within phagocytic cells stimulated by bacteria or parasites, to be microbicidal.
Reticuloendothelial system
A network of phagocytic cells.
