Circulation
CUSHING SYNDROME
- Cushing Disease: ACTH secreting tumor in pituitary
- Small cell carcinoma of the lung: ACTH production
- Adrenal gland adenoma/carcinoma
- Iatrogenic (exogenous)
CORTISOL INSUFFICIENCY
- Waterhouse Friderichsen Syndrome: Neisseria meningitis
- Stress in chronic adrenal insufficiency
- cold turkey steroids
, - Addison disease (caused by autoimmune, tuberculosis, AIDs, fungal infections, metastatic
cancer (lung & breast) and systemic conditions.
- pituitary/hypothalamic tumor/infarction/trauma
- Adrenal crisis
HYPERTHYROIDISM
- Graves disease: autoantibodies bind to TSH receptors & stimulate thyroid hormone production
outside of TRH/TSH
- Toxic multinodular goiter
- Toxic thyroid adenoma
HYPOTHYROIDISM
- Hashimoto Thyroiditis: chronic lymphocytic thyroiditis; immune response to thyroid antigens;
depletion of thyroid epithelial cells associated with lymphocytic infiltrates (B & T cells) and
fibrosis; increases risk for b-cell lymphoma.
- Myxedematous crisis: invasive surgical procedures in a hypothyroid patient can cause this
thyroxine (T4) --- levothyroxine - T4
triiodothyronine (T3) --- liothyronine - T3
