Q

treatment for lichen sclerosis?

Q

radical vulvectomy, when is it used?

A

invasive squamous cell carcinoma / melanoma

if basal cell carcinoma / = less disfiguring

26
Q

what is pathophysiology of pre-eclampsia?

A

placental endothelial cell dysfunction / vasospasm

27
Q

what are drawbacks of methyldopa in pregnancy for acute HTN episodes?

A

slow onset

sedating

28
Q

nitroprusside + HTN crisis?

A

last resort: cyanide = byproduct

29
Q

effect of hyperglycemia on fetus (mechanism)

A

hyperinsulinemia –> fetal hypoxia –> incr. erythropoiesis –> polycythemia –> ischemia/infarction

30
Q

effects of hyperglycemia on fetus post partum (lab values)

A

hypocalcemia (PTH suppression)
hypoglycemia
hyperbilirubinemia
polycythemia

31
Q

features of severe pre-eclampsia

A 
BP > 160/110
thrombocytopenia < 100K
serum creatinine > 1.1 
elevated transaminases
pulmonary edema
new onset visual/cerebral symptoms
32
Q

how does pregnancy incr. the likelihood of carpal tunnel?

A

estrogen –> incr. interstitial edema –> incr. carpal tunnel pressure

33
Q

what are features suggesting malignant discharge?

A

unilateral
bloody/serous
palpable skin changes

34
Q

what are the lab derangements in hyperemesis gravidarum?

A

hypokalemia, ketonuria

35
Q

clinical presentation of hyperemesis gravidarium?

A

severe, persistent vomiting
ketonuria
>5% loss of pre-pregnancy weight

36
Q

what is treatment for hyperemesis gravidarum?

A

hydration
ginger
pyridoxine +/- doxylamine

37
Q

what are risk factors for hyperemesis gravidarium (when does it present)

A

multifetal gestation / molar pregnancy

incr. placental mass –> highest hcg @ 10-12 wks (true for all women)

38
Q

what are causes of elevated maternal serum AFP?

A

produced by: fetal yolk sac, liver, GI tract
open neural tube defects
fetal abdominal wall defects (gastroschisis / omphalocele)
multiple gestation
fetal congenital nephrosis + benign obstructive uropathy

39
Q

what are some treatments for urge incontinence?

A

oxybutynin - anticholinergic

40
Q

for what type of incontinence is urethropexy used?

A

stress

41
Q

early decel - visual finding + etiology?

A

symmetric to contraction
gradual (> 30s from nadir to onset)
fetal head compression (possibly normal)

42
Q

late decel - visual finding + etiology?

A

occurs after contraction

cause: uteroplacental insufficiency

43
Q

variable decel - visual?

A

not necessarily assoc. w/ contractions
abrupt (< 30s from nadir)
(duration > 15 s, < 2 min)

44
Q

variable decel etiology

A

cord compression
oligohydrmanios
cord prolapse

45
Q

med treatment for acute abnL uterine bleeding?

A 
high dose IV/oral estrogen
high dose combined OCP
high-dose progestin (if E contraindication)
tranexamic acid (if both P/E contraindicated)
46
Q

what is mechanism of high E for acute uterine bleeding?

A

rapidly regrow endometrium from prolonged heavy bleeding

47
Q

fetal hydantoin syndrome

A

midfacial hypoplasia, microcephaly, cleft lip/palate, digital hypoplasia, hirsuitism, dev’t delay

48
Q

signs of congenital syphilis

A

rhinitis (snuffles) + skin lesions

later: keratitis, hutchinson, saddle nose, deafness

49
Q

fetal hydantoin syndrome vs. fetal alcohol syndrome

A

fetal alcohol doesn’t have cleft palate / excess hair

50
Q

where does placental abruption occur?

A

bleeding b/w decidua & placental interface –> placental detachment –> no exchange to fetus

51
Q

how to manage placental abruption?

A
  • IV access

- if stable vitals + > 37 wks –> vaginal delivery (maybe w/ oxytocin augmentation)

52
Q

what must be r/o w/ placental abruption?

A

placental previa

53
Q

how does ABO incompatibility occur & how does it present?

A

group O mother w/ a group A / B
mild anemia / neonatal jaundice - treatable w/ phototherapy
milder response than Rh(D) incompatibility

54
Q

what is treatment for adenomyosis?

A

hysterectomy

no other options

55
Q

molar pregnancy progression to choriocarcinoma

A

20%

56
Q

molar pregnancy + ovary findings

A

theca lutein cysts

57
Q

pregnancy markers

A

progesterone > 25

58
Q

A

DVT, PE, cardiovascular disease, stroke, breast/endometrial cancer, melanoma, hepatic tumor, abnL liver fuxn
