25
What are causes of secondary menorrhea (had a period, then it stopped)?
Pregnancy Anovulation (missing progesterone) Ovarian Failure (low estrogen, premature menopause) Outflow tract obstruction (Asherman Syndrome)
26
What is the criteria for secondary amenorrhea?
absence of menses for 3 months with prev regular menses or absence of menses for 6 months with previously irregular menses
27
How to work up secondary amenorrhea?
Urine B-hCG (pregnancy) TSH (cause of anovulation) prolactin (cause of anovulation) FSH (rule out premature menopause/premature ovarian failure)
28
When evaluating secondary ammenorrhea, what is your next step if prolactin level is elevated or if it is normal (and pt not pregnant)?
elevated - repeat when fasting, if still high, get MRI to r/u pituitary prolactinioma normal - progesterone challenge test to check for correct levels of estrogen \*if pt withdrawal bleeds, dx is anovulation \*if pt does not bleed - low estrogen or outflow tract obstruction
29
When evaluating secondary ammenorrhea, how do you evaluate for low estrogen?
Do an estrogen-progesterone challenge test - if bleeds, test is positive and means low estrogen, confirm with FSH level - if no bleeding, test negative - outflow obstruction (not hormonal)
30
How do you evaluate for anatomic problems causing secondary amenorrhea?
hysterosalpingogram by IR
31
What is Asherman syndrome and how to tx?
intrauterine scarring/adhesions from PID or trauma (uterine currettage, myomectomy) \*surgical tx to lyse adhesions, give high dose estrogen to try to grow healthy endometrium \*intrauterine balloon allows for healing of uterine walls
32
What causes anovulation?
stable estrogen (low or high) - no variation means you don't go through a normal cycle
33
How to dx (s/sx) and work up concern for ectopic pregnancy?
s/sx: pain, bleeding, amenorrhea 1. serum quantitative b-hCG 2. blood type and Rh status (if Rh neg - need to give RhoGAM) 3. CBC 4. Transvaginal US (show no intrauterine gestational sac)

At what b-hCG level should you be able to see an intrauterine gestational sac?
1500
35
How to tx unruptured early ectopic pregnancy?
Methotrexate IM to destroy pregnancy tissue (if b-hCG \<5000, ectopic mass \<3.5 cm, and no cardiac activity) f/u b-hCG on days 4 and 7 (see fall by day 7) and then weekly until fall to 0
36
How do you manage a pt with bleeding, pain, and b-hCG that is \<1500 and no intrauterine sac?
follow the p-HCG, should double every 2- 3 days and repeat US when the level is higher \*if b-hCG doesn't maintain this rate or levels off - suggestive of ectopic
37
How do you manage an unstable ectopic pregnancy?
emergency laparotomy to stop hemorrhage
