Q

Premature ovarian failure causes/ hormone levels

A

can be due to AI/chemo/radiation. Low ER, so high fsh and lh because no negative feedback. FH/LH >1

25
How does peripheral fat make more androgens?
aromatizes androgens to ER made in adrenals
26
Irregular cycles in pubertal females
Normal, btw. But caused by HPA producing inadequate hmns
27
LH Levels in PCOS
Elevated
28
How to confirm IUFD
US. autopsy fetus and placenta to figure out why
29
Missed abortion
CLOSED OS. brownish discharge. no passage of contents. still in gest sac
30
Complete abortion
Empty uterus. Pain subsides after passage of contents. CLOSE OS
31
Amenorrhea, normal breasts, absent pubic and axillary hair, absent internal reproductive organs, 46 xy, male-range testosterone
Androgen insensitivity (Mullerian agenesis will have 46 xx)
32
How to suppress lactation ?
No drugs - just decrease nipple stimulation - tight bra and ice packs and such
33
Abnl MSAFP. Next step?
US - multiple gestations and dating error more common than NTD/Trisomy
34
Retained POC, increased vascularity, thick endometrial stripe, echogenic material in cavity on pelvic US. Fever, chills, abd pain, bloody/purulent d/c,
Septic Abortion - history will tip you off as well
35
Septic Abortion Tx
Broad spectrum Abx and suction and curettage - emergency
36
BPP score of 4 or less
Deliver, regardless of fetal lung maturity. If after 26 weeks.
37
BPP score of 6 with oligohydramnios
If less than 32 weeks - monitor daily | If greater than 32 weeks - deliver immediately
38
BPP score of 6 without oligohydramnios
If greater than 37 - deliver | If less than 37 - check again in 24 h, deliver if not improved`
39
Arrest of stage I labor, tx?
Amniotomy/pitocin. C Section if all else fails
40
Arrest of stage 2 labor, tx?
Pitocin, assisted vaginal delivery or c section
41
Initial tx for PCOS to induce fertility?
weight loss
42
Cone biopsy v colpo and targeted biopsy?
Cone - for higher grade lesions where cytology and targeted biopsy do not correlate Colpo/targeted - for lower grade lesions to rule out CIN
43
How often should women over 50 get mammogram?
Every year, even if asx or no RFs
44
OCPs are associated with decreased risk of what cancers?
Ovarian and endometrial
45
dysmenorrhea causes?
endometriosis more common than leiomyoma
46
adnexal mass in postmenopausal female. Initial workup includes?
Transvaginal US, CA125. Don't needle aspirate
47
First trimester. Mom wants to check for possible chromosomal abnormalities. What test do you do?
Chorionic villus sampling. Early amniocentesis can be done if CVS can't
48
Most significant RF for fetal limb reduction in CVS?
Gestational age. Higher risk at less than 10 weeks
49
Vaginal d/c and vulvar pruritis. Thin, malodorous d/c, foul smelling with marked vaginal and vulvar erythema. Increased vaginal pH (5-6). Dx?
Trichomonas vaginalis - may look like BV, but BV does not typically have inflammation and pruritis.
50
Variable decelerations. Caused by and tx?
Cord compression. Give mom O2 and change position. Variables are typically abrupt (30s from onset to nadir)
51
Late decels. Caused by and Tx?
UP insuff. DELIVER. Gradual (greater than 30s from onset to nadir)
52
1) Most effective parameter to measure fetal weight in US in suspected growth restriction? 2) How do we differentiate asymmetrical from symmetrical growth restriction
1) Abd circumference | 2) head to abdomen circumference ratio
53
Quad screen for Downs? for Edwards? (MSAFP, BhCG, Estriol, Inhibin A)
Downs: hi BhCG, hi inhibin A, lo MSAFP, lo estriol Edwards: lo everything
54
LH/FSH in turners?
both elevated. Ovarian dysgenesis leads to no inhibitory feedback, so really high fsh and lh
55
Treatment for threatened abortion (which typically occurs in first trimester?)
REassurance and follow up. No need for hospitialization
56
Mom, multiple spontaneous abortions. Positive VDRL, prolonged PTT
Think Antiphospholipid abs - tx with LMWH and ASA
57
Abnormal uterine bleeding in adolescent. reason? tx?
Most likely due to immature HPA/ovarian axis, so you get anovulatory cycles. Persistent endometrial proliferation followed by heavy menses. Tx - oral progestins, estreogens, OCPs (all high dose), or tranexamic acid
58
respiratory distress in pre-E?
Probably due to pulm edema. Common sequelae of Pre-E. Magnesium tox would have NM probs and decreased Resp effort
59
Cervical mucous is thin/clear, can stretch to 6 cm, basic pH, will demonstrate ferning
This is ovulatory phase.
60
treatment for vaginismus?
kegels and pneumatic dilaiton
61
IUFD in a mom with low coag profile. What do you do?
Induce labor. Mom may develop DIC with retained fetus
62
What BhCG level do can wee see IUP on transvaginal US?
1500 +
63
Granulosa theca cell tumors secrete what hormone?
ER
64
What endocrine disorder can mimic menopause sx?
Hyperthyroid. Get FSH/TSH to figure out
65
Hypertensive drug of choice in pregnancy?
Hydralazine/labetalol > mdopa
66
how do you allow for premature ovarian failure patients to become pregnant?
in vitro fert with egg donor. GNRH and such wont help. low er, HIGH FSH and LH.
67
Cystic mass in premenopausal woman. Fluid aspirated is clear/yellow. What's the next step?
Just observe. RTC in 4-6 weeks. Only send for cytology if fluid is bloody or foul smelling
68
Stress incontinence. Tx?
kegels and urethropexy
69
Vasa previa v Placenta previa. When there's bleeding how do you know the difference?
Vasa: baby bleeding. So you;ll see late decels and UP insuff. Normal mom vitals Placenta: mom's vitals will be wacko
