18
Q

The most common osteoporotic fracture are _______ because they are rich in ___ bone

A

vertebral fractures
spongy bone

19
Q

what are the etiologies of osteoporosis?

A
  • Decreased levels of estrogen & testosterone
  • Inadequate levels of vitamin D, calcium, magnesium
  • Alterations in OPG/RANKL/RANK system
  • Postmenopausal osteoporosis:
    ↑osteoclast activity and changes in OPG
  • Glucocorticoids:
    ↑RANKL expression, inhibit OPG production by osteoblasts causing lower bone density
20

glucocorticoids
SSRI
PPI
seizure medications: phenytoin (dilantin) and carbemazepine (tegretol)
Thyroid replacement
anticoagulant

A

Increased intake of purine rich foods (seafood, red meat)
ETOH (beer), fructose-soft drinks
