  1. Adernal cortex fails to produce enough cortisol and aldosterone
    May be from pituitary problems or autoimmune disease
    Addison's disease
  2. Overproduction of the hormone cotrisol
    common due to over administration of steriods or tumor
    Cushing's Syndrome
  3. What kind of tumors mostly cause Cushing's syndrome?
    • Lung or Pancreas
    • but could be adrenal tumors
  4. Cushing's diagnosic tests
    • 24-Hour urine for free cortisol
    • *Levels of 50-100 mcg/day in adults indicate a cushings
    • High-Dose decamethasone suppression test used for borderline results of 24-hour urine cortisol
    • CT and MRI of pituitary and adrenal glands
    • CBC
    • Electoylyte panals (false postives can occur in alcoholics and liver failure)
    • High or normal ACTH levels indicate ACTH-dependent Cushing's disease-(hormone produced by pituitary)

    • Monitor I&Os
    • Critical period for circulatory instablitiy ranges from 24-
    • 48 hours

    • ACTH stimulation test (best one)
    • -blood cortisol, urine cortisol, or both are measured before and after a synthetic form of ACTH is given by injection.
