Glossary for Redness

Medical terms related to Redness or mentioned in this section include:

  • Abalone poisoning: Abalone are a shellfish that are commonly eaten by humans. The internal organs of the abalone sometimes contain toxins which can cause various symptoms. The toxins are believed to originate from toxic components in the abalones diet.
  • Abdominal muscle strain: Damage to the abdominal muscle due to over-stretching of the muscle tissue. The damage involves tearing the muscle tissue. Small blood vessels may also be damaged which can cause bruising. The symptoms may vary from mild to severe depending on the severity of the damage.
  • Abscess: This is an area of puss collected in a cavity which is constituted by necrotised tissue
  • Accelerated hypertension: Accelerated hypertension is a condition characterized by a rapid increase in blood pressure. The condition is a medical emergency which can cause organ damage if not treated promptly.
  • Actinic keratosis: Gradual thickening of outer skin layers caused by excessive exposure to sunlight. Also called senile keratosis, senile wart or solar keratosis.
  • Acute stress disorder: An acute anxiety state
  • Adrenal Cancer: A malignant cancer that develops in the adrenal gland. The tumor may be nonfunctioning (does not produce hormones) or functioning in which case excessive levels of hormones can cause a variety of symptoms depending on which hormone is involved. Adrenal hormones made in the cortex (outer part of the gland) are aldosterone, corticosteroids and androgenic steroids. Adrenalin and noradrenalin are the hormones made in the medulla (central part of the adrenal gland).
  • Adrenal adenoma, familial: A benign tumor that develops in the adrenal gland and tends to run in families. The tumor may be nonfunctioning (does not produce hormones) or functioning in which case excessive levels of hormones can cause a variety of symptoms depending on which hormone is involved. Adrenal hormones made in the cortex (outer part of the gland) are aldosterone, corticosteroids and androgenic steroids . Adrenalin and noradrenalin are the hormones made in the medulla (central part of the adrenal gland).
  • Adrenal gland hyperfunction: Excessive activity of the adrenal gland which causes excessive production of one or more adrenal hormones (aldosterone, corticosteroids, androgenic steroids, epinephrine and norepinephrine). The increased adrenal gland activity may be caused by an adrenal gland tumor or by excessive stimulation of the gland. Pituitary hormones stimulate adrenal gland activity.
  • Adrenal hypertension: Adrenal hypertension is high blood pressure caused by adrenal gland problems. For example, an adrenal tumor can cause excessive production of aldosterone which in turn causes salt-retention and high blood pressure. Severity of symptoms varies depending on the underlying cause.
  • Adrenal incidentaloma: A tumor of the adrenal gland that is discovered incidentally while performing an imaging examination for reasons other than an adrenal tumor. The tumor may be asymptomatic or can causes excessive secretion of adrenal hormones and resulting symptoms. The tumor may also be malignant or benign.
  • Adrenal medulla neoplasm: A tumor that develops in the part of the adrenal gland called the medulla which produces adrenalin and noradrenaline. The tumor is usually benign but can be malignant.
