Gyn+OB OME Flashcards
Ultrasound and ca125 indicated to screen for cervical cancer when
Is increased surveillance adequate in these pts
When pt has BRCA1/2 mutation
No ppx hysterectomy oopherectomy mastectomy is superior to surveillance
BRCA1/2 mut predisposes to what cancers
breast ovarian uterine
Risk factor for vaginal and vulvar squamous cell carcinoma
HPV
Vag and vulv scc just like cervical csused by hpv
Endometrial cancer is driven by ______
Estrogen
64 F with maligmant ascites, which gym cancer to suspect
Ovarian cancer
Biggest risk factor for ovarian cancer
Ovulation
Teenage girl has huge obvious cystic teratoma by history and ultrasound, next step cystectomy or CT to better stage and characterize
cystectomy
age of patient and size of tumor make diagnosis clear (serous cystadenoma), no need for radiation exposure
why is TAH + BSO required for breast and uterine carcinomas?
total abdominal hysterectomy and bilateral salpingoopherectomy
estrogen responsive tumors
estrogen comes from ovaries
must take ovaries out in case mets
what % of women with infertility are found to have endometriosis
30%
define preterm labor
v37wks
tf
ovarian torsion often occurs seated not doing anything / at rest
T
often does
tf
treat 3cm simple ovarian cyst with oral contraceptives
f
oral contraceptives don’t affect ovarian cysts – used ot think so but not anymore
for 3cm, just repeat US in 3 mos to check but expecting spontaneous resolution
tubo-ovarian abscess is a complication of
pelvic inflammatory disease
1st and 2nd line tx of endometriosis
far down the line definitive therapy
nsaids
OCPs
laparoscopy
3cm smooth fluid-filled cyst in otherwise normal child-bearing age female, what is it likely, next step
Likely a functional follicular cyst (ovulating ovaries make them every month)… low risk (v10cm smooth thin-walled no septations)
Reassurance, typically regress weeks to months
rectocele causing constipation, surgery planned for next week, how to treat constipation till surgery
transvaginal digital reduction of rectocele - to restore normal alignment of colon and alow expulsion
how do kegel exercises treat vaginismus
contract the pelvic floor, relax the vaginal muscles so they can be gradually dilated
Mittleschmerz pain
Peritoneal pain from rupture / bleed from functional ovarian cyst or follicle
primary causative organism in bacterial vaginosis
gardnerella
choose between gonorrhea and chlamydia for cause of cervicitis on test
choose chlamydia
more prevalent
what kind of incontinence do neurogenic bladder and hypertonic bladder cause
neurogenic - overflow incontinence
hypertonic - spastic/urge incontinence
diabetes
ms
spinal lesion
are risk factors for what kind of urinary incontinence
neurogenic bladder - overflow incontincence
when to get ct scan for urothelial cancer
to stage – CT good at identifying mets, not primary urothelial cancer – get cystoscopy and biopsy for that
oxybutinin moa
use
urinary smooth muscle antispasmotic
also anticholinergic at urinary smooth muscle
tx overactive bladder (hyptertonic, spasmotic)
how does fibroid surgery lead to vesico vaginal surgery
trauma from surgery, or retained stitch, etc…. can lead to epithelialized tract between two epithelia…
when to get urodynamics
eval urinary incontinence when not sure stress vs urgency
overflow incontinence aka aka
hypotonic aka neurogenic bladder
when to use foley vs bethanecol or doxasosin for neurogenic bladder
foley for acute relief of hydronephrosis
bethanecol or doxasosin for long term treatment
When to perform external cephalic version of fetus
When baby is breech after 37 weeks (before 37 weeks the fetus is likely to spontaneously cephalize)
TF
Mom with PPROM and fever and tachy fhm needs betamethasone
F
Abx - broad spectrum pip/tazo or amp/gent/metro
And deliver asap… don’t wait to deliver with evidence of chorioamnionitis
TF
Abx for PROM even if no signs of infection yet
T
Not laboring yet, may take time, ppx against infectiom
When to use cerclage
First trimester presence or historynof cervical incompetence
aka way before labor, mist be removed before cervical changes in labor or else damage
TF
One sac, two placentas is possible
F These are possibe: One sac one placenta Two sacs two placentas Two sacs one placenta
What kind of twinning risks cord entanglement
One sac one placenta
What kind of twinning risks twin-twin transfusion
Two sacs one placenta
What kind of twinning risks malpresentation and premature birh
Two sacs two placentas
Types of twinning according to time of separation
Earlier separation, less shared
Separate eggs - dizy dichor diamn Day 0-3 - monozy dichor diamn Day 4-8 - monozy monochor diamn Day 9-12 - monozy monochor monoamn Day 12+ - conjoined mono mono mono
Each additional gestation pushes the EDD up about…
4 weeks (from mono edd 40 wks)
Quadruplets cooking in there, edd?
28 weeks
Each additional gestation pushes the EDD up about 4 weeks
Major cause of DIC in delivery
Placental embolization
How does amnionic fluid embolism present differently from placental embolism
Amnionic fluid PE w dyspnea amd hypoxia then maybe DIC
Pacental embolism DIC
Blood vessels to edge of delivered placenta implies…
And how to treat…
Retained parts of placenta
If PPH - D&C, then uterine artery ligation, then total abdominal hysterectomy ad needed
Retained placenta has long term complication of this cancer
Choriocarcinoma
How to follow up a DandC of a retained placenta
Serial bHCG’s for about a year to make sure no choriocarcinoma developes
Algorithm for workup of decreased fetal movement
Doppler for fetal heart tones (alive)
NST
NST w vibrioacoustic stim
BPP
CST or repeat BPP 24h if BPP 3-7 and preterm
Deliver if BPP 2 or less or CST abnorm or BPP 3-7 and term
Only go to next one if you get an abnormal… if normal.. can repeat at follow-up to acknowledge mom’s feelings
Act on BPP score
8-10 reassure and repeat weekly to check again
3-7 consider delivery if term, if preterm consider steroids and try to keep cooking a bit longer and do CST or repeat BPP IN 24hrs to help decide whether to deliver
0-2 deliver or else baby is going to die
In which does fetus decompensate faster, placenta previa or vasa previa?
Vasaprevia
What Rh antibody titer would cause you not to give rhogam because Mom already has anti-Rh abs
1:8 or greater
Painless genital ulcer
Think…
Dx by…
Painless genital ulcer
Think syphilis
Dx by dark field microscopy
Dx heamophilis ducrei in painful genital ulcer
