Explain how PTH works?
Explain the difference between primary, secondary and tertirary
Explain what PTH and Ca levels you would find with each type
PTH + vit D -> increase serum Ca
PTH does this by:
= increasing osteoclast activity
= causing renal retention of Ca
= increasing gut absorption (vit D does this too)
Primary - mostly caused by adenomas
Secondary - caused by parathyroid gland hyperplasia in response to one of the mechanisms not working properly e.g. renal failure
Tertiary - as a result of all 4 paratyhyroid glands hyperplasia due to prolonged secondary hyperparathyroidism
Primary
- Increased PTH, increased Ca
Secondary
- increased PTH, normal or low Ca
Tertiary
- increased PTH, normal or high Ca
What XR finding is associated with hyperparathyroid?
Pepper pot
What is the link between calcium and phosphate?
As calcium increases, phosphate decreases
