Parathyroid/Adrenal Disorders Flashcards
What does PTH regulate
Calcium and phosphorus
Primary hyper parathyroid secondary
Most common cause: benign adenoma, previous head/neck injury
Secondary HPT
Response to conditions that cause hypocalcemia
Tertiary
Autonomous secretion of PTH
-kidney transplant patient after long term dialysis
Hyperparathyroidism
Leads to hypercalcemia and hypo phosphate
- weakness, loss of appetite, emotional disorders
- complications: renal failure
If autotransplantation fails or is not possible
Need calcium supplements for life
No surgical therapy hyper parathyroid
- biphosphates
- calcimimetic
- diuretics
Treatment of acutely elevated serum calcium levels
IV NaCl and loop diuretics
Hypo parathyroid
Hypocalcemia
- causes: removal of parathyroid and damage to vascular supply, hypomagnesemia, idiopathic
- M: tetany, positive chvostek and trousseau
- T: supplements and vitamin d
Tetany treatment
Rebreathimf
Adrenal cortex releases
Corticosteroids
-and androgens
Cushing syndrome
Excess of corticosteroids(glucosteroids)
- most common cause: ACTH secreting pituitary tumor
- weight gain (face and trunk), hyperglycemia, protein wasting
- mineralcorticoid excess may cause HTN and fluid retention
Cushing diagnostics
- 24hr urine for free cortisol (>120)
- CT and MRI
Cushings treatment
-suppress cortisol production
Surgery
-tumors
If cushing syndrome develops during the use of corticosteroids
Gradually discontinue and decrease dose
Convert to alternate day regimen
