17
Q
46XX w/primary amenorrhea
A
Mullerian agenesis= no Müllerian ducts = no uterus or upper vag+ boobs, pubes, ovaries but -uterus = primary amenorrhea
18
Q
46XY w/primary amenorrhea
A
Androgen insensitivity=no androgen receptor! Balls present and making testosterone but due to lack of receptor wolf degrades, MIF degrades mullerian.+testes +breast -pubes -uterus =primary amenorrhea
19

A
Turners!No ovaries and no estrogen!Streak ovaries, short stature, webbed neck, infertility, amenorrhea, broad chest, urinary track abnormalities, bicuspid aortic, aortic core Tatian, dysgerminomas risk, normal intelligence- ovaries,breast,pubes but + uterus = primary amenorrhea

A
15, 13
25
testosterone in mullerian agen vs androgen insens?
normal in mullerian but elevated in androgen insen.
26
what does a negative progesterone challenge test tell you?
absence of withdrawal bleeding is caused by either inadequat estrogen priming of the endometrium or outflow tract obstruction(imperforate hymen).
27
what does a positive Progesterone challenge test tell you?
diagnostic of anovulation! = need to give cyclic progesterone to prevent endometrial hyperplasia. give Clomiphene if pregnancy is desired.
28
What does a negative estrogen-progest challenge test tell you?
diagnostic of outflow obstruction or endometrial scarring(Asherman Syndrome) = do hysterosalpingogram(HSG) to ID
29
What does a positive estrogen-progest challenge test tell you?
bleeding = there just wasnt enough estrogen in the first place. look at FSH to ID etiology.*elevated FSH = ovarian failure*low FSH = need to r/o brain tumor.
30
what is asherman syndrome?
scarring of the uterus due to extensive uterine curettage and infection-producting adhesions.
31
define secondary amenorrhea
women of reproductive age who has stopped having periods for >6 months. ^nobody waits that long to investigate though lol
32

33
how does hypothyroid cause secondary amenorrhea? how do you treat?
hypothyroid = increased TSH = increases prolactin production = inhibits GnRH causing amenorrhea.*will also see dec FSH & LH(duh) just like wiht a prolactinoma.tx: levothyroxine
34
work up and tx of prolacintoma
suspect if galactorrhea or amenorhea. get prolactin level then MRI.tx: Pramixpaxole < cabergoline
35
what drugs will cause secondary amenorrhea?
DA antagoinist like atypical antipsychotics.
36
hormone levels in menopause...
elevated FSH and LH
37
28 yo women who has 2nd amenorrhea. FSH and LH are elevated. U/S shows many follicles. dx? tx?

40
causes of vaginal bleeding in postmenopausal women. Whats the most common?
1. Atrophy(MC)2. Endometrial Carcinoma3. Hormone Repacment Therapy(HRT)
41
What are the escalating steps for heavy, life threatening bleeding.
*always remember 2 large bore IVs + IVF1. IV estrogen to stop2. Balloon tamponade3. D&C4. Uterine A. Embolization5. Hysterectomy
42
PALM COINE
Polyps, Adenomyosis, Leiomyomas, Malignancy, Coagulopathies, Ovarian Dysfunction, Endometrial probs, Iatrogenic = IUD, Not Yet Classified^causes of anatomic causes of uterine bleeding
43
What are Fibroids?
Leiomyomas in the Uterus = benign. Asymmetric, hard nodules, painful, may have iron def due to bleeding, can cause problems wiht pregnancy or obstruction due to location(due to size). Will increase in size with estrogen. dx: U/S tx: w/OCP
44
Adenomyosis. tx?
endometrium grows into the myometrium. symmetrically enlarged, soft, tender uterus, menorrhagia and dysmenorrhea
45
when is abnormal uterine bleeding(AUB) normal?
near menarche or menopause
46
how do you dx AUB? Tx?
exclusion! tx: OCP & NSAIDs to reduce bleeding
47
What happens in Polycystic ovarian Syndrome?
ovary is replaced by thousands of follicles that produce large amounts of estrogen which then is converted to testosterone = fat, hairy, irregular menses, deep voice, trouble getting prego, DM, dyslipidemiadx: LH/FSH >3 makes dx. elevated testosterone but normal DHEAStx: OCP + Metformin(reduces androgens), clomiphene to help with getting prego
48
IUP w/bleeding, closed OS, U/S shows live baby....
threatened abortion, get bed rest and see if its okay.
49
IUP w/bleeding, open OS & U/S shows dead baby..
inevitable abortion
50
IUP w/bleeding, + passage of clots, open OS, retained parts...
Incomplete abortion
51
IUP w/bleeding, + passage of contents, closed OS, U/S shows nothing...
complete abortion
52
1st trimester to induce abortion
misoprostol
53
Rh - mothers need to be given....
Rogam! = mom doesnt Rh factor and will have Ab to this factor -- baby will have this factor = give rogam toprevent abortion
54
UPT +, vaginal bleeding...next step?
do U/S to diff = baby, abortion, molar prego or ectopic pregnancy
55
How do you use B-quant in ectopic prego?
B-quant = bhcg.*If >/=1500 and in fallopian tube = ectopic.*if <1500 and in fallopian tube = wait! may still be traveling to uterus = wait 48hrs and try again.
56
When can you use methotrexate + leukovorin for ectopic pregnancy?
if bhcg <5000 or 8000, <3cm, no heart tones, moms not on folate
57
tx for non-ruptured ectopic prego...
salpingostomy = reach in and remove
58
Amenorrhea
No peroids for 3+ consecutive months
59
Swyer Syndrome
46XY congenital lack of testes. Resulting in no MIS causing female appearance
60
What are the 3 phases of the mentral cycle? Days?
1. Menstrual phase (1-4) drop in E&P cause break down of functional layer2. Proliferate phase( 5-14): follicle grows producing increasing estrogen which promotes the growth of endometrium and inhibits LH(this theca and progest)3. Secretory phase(14-28) high estrogen causes + feedback on LH causing theca to increase progesterone = stabilizing endometrium.
61
@d28 what happens if prego?
bhCG produced by implanted egg supports CL allowing it to continue to produce progesterone until wk 10 when placenta takes over allowing CL to degrade, bhcg levels to fall but E&P levels maintained
62
HD estrogen will....
Stimulate LH(test+P)
63

67
can you give OCPs to reduce the size of ovarian cysts?
nope! they dont work dont do this
68
what do you give a young girl wiht irregular, heavy bleeding? why?
NSAIDs, young women who just started menarche will often have abnormal cycles likely do to anovulation and NSAIDs are kinda like pushing the reset button on it to regulate the cycle.
69
what do you do when you find a cysts between 3-10cm?
reimage within 12 weeks(U/S) to show any growth. if not just ignore it. if less than 3cm dont need to reimage.
70
