Q
“third trimester” labs
A
weeks 20-28 test for gestational dm (1 hr gtt , +/- 3 hr gtt) anemia Hgb<10 alloimmunization -Rh-ag - mom; screen for Rh-ab’s, have to be right type and titer to cause fetal anemia

greater than or equal to 1:8. Get transcranial doppler next
25
If Rh- mom has anti Rh antibodies \>1:8, what do you do next?
get transcranial doppler to see if baby is compensating for anemia with increased cardiac output. If no increased flow -- no worries! If flow is increased: delivery if 32w+, if younger than 32w do PUBS (test hemoglobin and transfuse)
26
what do you do with mom who is Rh ag and antibody negative with Rh+ baby...
delivery, hemorrhage, procedure, csection -- any blood mixing...**give Rh(D)Ig at 28 weeks and within 72hrs of mixing event**
27
describe cardiovascular changes in pregnancy
bp drops because systemic vascular resistance goes way down.
there is compensatory increased cardiac output because HR goes up a bit and preload goes way up because RBC increase a ton
dont forget that even though there are more RBCs, HgB actually drops because there is also a bigger rise in plasma volume
anemia in preggars is \<10

AND
\>2 mid trimester preg loss, \>3 unexplained preterm deliveries , clinical diagnosis (a short cervix alone is not enough)
32
what's the first thing you should do when mom has low BP
lay on left side. she might have her uterus compressing the IVC
33
fetal hydrops
generalized edema of the fetus, can be cause by fetal anemia, infections like parvovirus B19, chromosomal abnormalities, congenital heart defects
34
threatened abortion
vaginal bleeding, fetal activity, cervical os is *closed.* this is reversible
avoid strenuous activity, weekly pelvic ultrasound until it goes one way or the other, rule out treatable causes of vaginal bleed, give Rhogam if Rh- mom
35
inevitable abortion
cervical os is open. can't do anything.
Option 1: expectant management if \<14wks, Surgical evacuation is usually recommended if evacuation does not occur after 4 weeks
Option 2: medical management. Pretreat with mifepristone first (if available) and then 24 hrs later, misoprostal
Option 3: Dilation and curettage

37
incomplete abortion
usually \>12wks, stuff in uterus and cervical canal, cervical os open
## Footnote
Option 1: expectant management if \<14wks, Surgical evacuation is usually recommended if evacuation does not occur after 4 weeks
Option 2: medical management. Pretreat with mifepristone first (if available) and then 24 hrs later, misoprostal
Option 3: Dilation and curettage. Preferred if hemorrhage or septic abortion
38
spontaneous abortion
\<20wks
downtrending bHCG, no fetal cardiac motion
do a pelvic exam to make sure bleeding is coming from uterus/cervix. If no fetal heart beat or the bleed is definitely uterine, do transvaginal ultrasound
39
stillbirth
\>20 wks
## Footnote
Spontaneous labor usually begins within 2 weeks of intrauterine fetal death. However, labor may be induced with oxytocin if maternal disease develops (e.g., coagulation abnormalities) or if the patient prefers induction.
Vaginal delivery is safer than cesarean section
Patients should be offered a fetal autopsy to determine the cause of death.

describe hormone axis that is responsible for puberty in females
96
you have a girl with precocious puberty and her bone scan shows bone age \>2 yrs above chronological age. What is your next step?
GnRH (leuprolide) stim test.
If LH is stimulated by leuprolide, then you know her hypothal--\> pituitary axis is active and it's a central condition. You need to look at brain with MRI. If tumor--\> resect. If no tumor--\> it's constitutional; treat with continuous leuprolide which turns *off* the axis!
if stim test did not raise LH, it's a peripheral lesion. Get US of adrenal glands, transvag US for ovaries, test DHEAS, testosterone levels, 17-hydroxyprogesterone in urine if considering congenital adrenal hyperplasia.
if cyst: reassure
97
congenital adrenal hyperplasia
can't make glucocorticoids and mineralcorticoids, so everything gets shunted to androgens. Percocious puberty. Give exogenous glucocorticoids and mineral corticoids and the body will chill out.
98

+hirsuitism
dx: transvaginal ultrasound.
resect (not malignant)
104
adrenal tumor
DHEA will be very high--\> virilization
testosterone is normal (ovaries are fine)
get CT or MRI to look at adrenal glands.
\*\*Do adrenal vein sampling to figue out which adrenal gland is hyperfunctioning because it can be the one without the mass
105
congenital adrenal hyperplasia
moderately elevated DHEAS, normal testosterone, hirsuitism
Get CT/MRI
**Dx: 17-OH-Progesterone in urine**
**(**high 17-OH-progesterone is a result of absent **21-beta-hydroxylase.** All the cholesterol goes to DHEAS bc cant make aldosterone and cortisol. Body freaks out and sends even more cholesterol ...even more DHEAS)

117
someone under 30 comes in with breast lump. What do you do?
wait for a couple of menstral cycles and see if it goes away. If it doesnt, get ultrasound which will show mass or cyst. you need to find out if its a problem so get fine needle aspiration.

121
what's difference between tamoxifen and raloxifen?
both are estrogen receptor modulators for breast cancer. Tamoxifen works better for breast cancer but risks DVT and endometrial carcinoma. Raloxifen doesnt work as well but also doesnt have these risks.
Tamoxifen causes endometrial cancer because it is a estrogen receptor antagonist in breast and a estrogen receptor agonist in the endometrium. go figure.
122
What are targeted breast cancer therapies?
If Her2Neu positive, traztuzumab or bevacizumab. Her2neu has worse prognosis. Know that traztuzumab can cause CHF that is NOT does dependent but is Reversible.
If Her2neu negative, give tamoxifen or raloxifen if PREmenopausal. Give aromatase inhibitor if POST menopausal (anastrozole, letrozole)

in constant contraction
126

inferior epigastric arteries
127
you can find pudendal nerve for nerve block at...
level of ischeal spine. palpate ischeal spine and inject 1 cm inferior and medial. be sure to aspirate so you avoid pudendal artery and inferior gluteal artery

pathophys of menopause
Numerical depletion of ovarian follicles with age → ↓ ovarian function → ↓ estrogen and progesterone levels → loss of negative feedback to the gonadotropic hormones → ↑ GnRH levels → ↑ levels of FSH and LH in blood (hypergonadotropic hypogonadism) → ↑ frequency of anovulatory cycles

symptoms of endometriosis
dysmenorrhea, chronic pelvic pain, dyschezia, dyspareunia, abnormal uterine bleeding
do exam for rectovaginal tenderness, adnexal masses
\*TVUS
laparoscopy is confirmative
171
medical treatment options for endometriosis
NSAIDs
OCPs
danazol (steroid)
GnRH agonist (buserelin, goserelin)
172
goserelin, buserelin
A gonadotropin-releasing hormone receptor agonist that can either be used to stimulate (via pulsatile administration) or suppress (via continuous administration, which downregulates GnRH receptors) LH and FSH secretion. Commonly used continuously to treat hormone-sensitive prostate cancer, precocious puberty, menorrhagia, and endometriosis. Used in pulsatile fashion to increase fertility
173
symptoms of PCOS
acne
hirsuitism
obesity, insulin insensitivity
infertility
maybe virilization
174
testing for PCOS
measure testosterone
LH:FSH ratio \>2
can measure 17-hydroxyprogesterone to rule out non classical congenital hyperplasia
check for metabolic syndrome (HgA1c, BG, lipid panel )
+clinical diagnosis overrules blood tests+
175

Free fluid in the pouch of Douglas in a pregnant patient should raise concern for -----
ruptured ectopic pregnancy
178
how does prolactinemia affect FSH, LH?
prolactin --\> negative feedback on GnRH --\> low FSH, low LH, low testosterone, low estrogen
179
why can hypothyroidism lead to galactorrhea?
low thyroid hormones will lead to upregulation of TRH and thus TSH. TRH will cross react in anterior pituitary and lead to more prolactin release along with more TSH

true or false: hormone levels are the same between women with and without PMS or PMDD
true, the amount of estrogen, progesterone are not different between women who have PMS, PMDD and those that don't. It seems that hormones play a role in PMS/PMDD but aren't sufficient to explain it

risks and benefits of systemic hormone therapy for menopause sx
if they have uterus, they must get estrogen AND progesterone bc unoppossed estrogen --\> endometrial cancer
taking E&P leads to increased breast cancer, coronary heart disease, stroke, VTE. decreased colon cancer and fractures
for women only taking estrogen, there was increased VTE but not cardiovascular disease
193
contraindications for HRT for menopause
cardiovascular disease, stroke, breast cancer, DVT hx, liver disease
combined estorgen-progesterone HRT --\> increased coronary heart disease, stroke, VTE. decreased colon cancer and fractures, decreased LDL and increased HDL
estrogen only HRT can only be given to ppl without uterurs. Only increased VTE
