Puberty/Menopause Flashcards
Adrenarche/ Gonadarache
Zona reticularis in adrenal starts making androgens, then gonadarche (pulsatile GnRH)
Adrenarche: ages 6-8
Gonadarche around age 8
Thelarche / pubarche / menarche
Thelarche (~10 y/o)→ pubarche (~11)→ growth spurt peak velocity (9-10)→ menarche (12-13, or usually ~2.5yrs after thelarche).
Earlier in AA, later in Caucasians / thin girls / etc.
True precocious puberty
Due to pulsatile GnRH secretion
True precocious puberty treatment
Treat with nonpulsatile GnRH
Menopause
Definition: 12 months of amenorrhea after last menstrual period.
Avg age 51, but big range.
Perimenopause
Before menopause
Can still have periods!

If history of osteoporotic fx…
Can treat with bisphosphonates right away without waiting for dexa results
Osteoporosis risk: when to order DEXA scan
Everybody @ 65 y/o, or @ 60 y/o if high risk
Treatment of osteoporosis
Bisphosphonates (if pathologic fx of hip or vertebrae, other fx and T-score -1.0 to -2.5, or Tscore < -2.5).
Should be taking 1000-1500 mg Ca daily no matter what; if osteoporotic, 800 IU vitD too
SERMs help with osteoporosis too.
Hormone replacement therapy: risk of unopposed estrogen
Unopposed estrogen → endometrial hyperplasia → endometrial cancer
If still have a uterus, need progestins too
Combined HRT dosing
Short period of time (6-12 mo), smallest dose
Combined HRT helps prevent
Helps prevent osteoporosis
