A patient with diabetic nephropathy developed secondary hyperparathyroidism. Hypehyroidism is seen in all of the following conditions, EXCEPT: 
Select and explain. 
A. Osteoporosis, B. Osteomalacia, C. Rickets, D. Chronic renal failure
A: Osteoporosis
Answer: A: Osteoporosis 
Explanation: In chronic kidney disease, hyperphosphatemia and decreased renal production of 1,25-dihydroxycholecalciferol (1,252D3) initially produce a decrease in ionized calcium. The parathyroid glands are stimulated (secondary hyperparathyroidism) and may enlarge, becoming autonomous (teiary hyperparathyroidism). In osteomalacia and rickets, hypocalcemia acts as stimulus to secondary hyperparathyroidism. Ref: Shoback D., Sellmeyer D. (2011). Chapter 8. Metabolic Bone Disease. In D.G. Gardner, D.
