Gynecology Flashcards
Ddx for abnormal vaginal odor
bacterial vaginosis *fishy odor, watery discharge
candidia yeast infection *creamy, cottage cheesy discharge
trichomoniasis (sexually transmitted) *green, vaginitis
How to work up abnormal vaginal discharge?

postiive fishy odor on whiff test
clue cells on saline prep
pH incr above 4.5
How to treat bacterial vaginosis?
metronidazole for 7 days
don’t need to tx partner
How do you dx and tx vaginal caindida infection?
more common after abx, immunosuppresion, DM
s/sx: burning, itchy, irritation, white thick clumpy d/c
KOH prep shows pseudohyphae
pH normal
tx: 1 dose fluconazole
Azole creams - multiple day tx
How do you dx and tx Trichomoniasis?
Saline prep with motile trichomonads
ph >4.5 (elevated)
purulent, green, foul smelling discharge, strawberry cervix, vaginal pain
metronidazole orally
*treat partner as well
What 2 things to think about with cervical motion tenderness?
PID
ectopic pregnancy
Is a pap smear diagnotstic?
no - only screening!!! must have a cervical biopsy to dx
How do you follow up an abnormal pap smear with a ASC-H or HSIL?
ob/gyn consult “pap smear shows _”
colposcopy and biopsy (if you see abnormalities)
What are the different findings with colposcopic biopsy results of abnormal cervical tissue and how do you tx?
CIN 1 - 1/3 thickness affected (mild)
*can remove or f/u with another pap in 1 yr
CIN 2 - 50% affected (moderate)
CIN 3 - full thickness (advanced)
tx: loop electrosurgical excision procedure (LEEP) to remove abnormalities or ablation with cryotherapy
Pap every 3-6 months for next 2 yrs to make sure doesn’t recur
What part of the cervix is tested with biopsy?
transition zone
What is the normal course of HPV infection of the cervix?
body will clear it on its own in 1-3 years
What are the possible results from a pap smear?
NIL -negative for lesions or malignancy
Atypical squamous cells (ASC) *undetermined significance or cannot exclude HSIL)
low grade squamous intraepithelial lesion
high grade squamous intraepithelial lesion
How do you f/u a pap smear that is abnormal with ASC-US (atypical squamous cells of undetermined sig)?
HPV DNA typing - can tell you if high risk type (16 or 18)
*if neg, done with w/u
*if type 16 or 18 - colposcopy and visually directed biopsies
How do you follow up an abnormal pap smear with LSIL?
if HPV test neg and age >30- repeat HPV/Pap in 12 months
if HPV not done or positive: colposcopy with visually directed biopsies
What does abnormal epithelium look like on colposcopy?
white epithelium, mosaicism, punctation, abnormal vessels
How do you f/u an abnormal pap smear in pregnancy?
most dysplasia will spontaneously regress after pregnancy (75%)
How do you treat cervical cancer that has progressed to invasive cancer?
hysterectomy (how much is taken out depends on depth of invasion)
What is the Ddx of pelvic pain and fever?
pelvic inflammatory dz
appendicitis
cervicitis (infection just in the lower genital tract)
extopic pregnancy (get B-hcg, usually unilateral)
endometriosis (chronic pain)
ovarian cyst
inflammatory bowel dz
How to w/u PID?
b-hcg
CBC, ESR
chlamydia and gonorrhea
STD (syphilis, HIV)
How to manage acute PID inpt and outpt?
inpatient (fever)
empiric goverage
Cefotetan IV (gonorrhea) and IV doxycycline (for chlamydia)
tx until afebrile x48 hrs and no tenderness
*pull out IUD?
outpt (not febrile) (14 days abx)
IM ceftriaxone x1, PO doxycycline 14 days, PO metronidazole 14 days
What are complications/sequalae of PID?
infertility, ectopic pregnancies d/t adhesions
chronic pain d/t adhesions
pelvic and fimbrial adhesions causing “frozen pelvis”
What are criteria for tx PID inpatient?
presence of an abscess
high fever >39
septic appearance, peritonitis
IUD in place
outpt tx failure
How do you dx and tx cervicitis?
mucopurulent cervical disharge
friability of cervical epithelium (bleed when touched with a q-tip)
no systemic complaints
nucleic acid amplification testing for chlamydia and gonorrhea
empiric - 1 dose azithromycin (chlamydia) and 1 dose cefixime (gonorrhea)
*if you have gonorrhea, tx for chlamydia no matter what the test result
*if only chlamydia - just tx chlamydia
What are causes of secondary menorrhea (had a period, then it stopped)?
Pregnancy
Anovulation (missing progesterone)
Ovarian Failure (low estrogen, premature menopause)
Outflow tract obstruction (Asherman Syndrome)
What is the criteria for secondary amenorrhea?
absence of menses for 3 months with prev regular menses
or
absence of menses for 6 months with previously irregular menses
How to work up secondary amenorrhea?
Urine B-hCG (pregnancy)
TSH (cause of anovulation)
prolactin (cause of anovulation)
FSH (rule out premature menopause/premature ovarian failure)
When evaluating secondary ammenorrhea, what is your next step if prolactin level is elevated or if it is normal (and pt not pregnant)?
elevated - repeat when fasting, if still high, get MRI to r/u pituitary prolactinioma
normal - progesterone challenge test to check for correct levels of estrogen
*if pt withdrawal bleeds, dx is anovulation
*if pt does not bleed - low estrogen or outflow tract obstruction
When evaluating secondary ammenorrhea, how do you evaluate for low estrogen?
Do an estrogen-progesterone challenge test
- if bleeds, test is positive and means low estrogen, confirm with FSH level
- if no bleeding, test negative - outflow obstruction (not hormonal)
How do you evaluate for anatomic problems causing secondary amenorrhea?
hysterosalpingogram by IR
What is Asherman syndrome and how to tx?
intrauterine scarring/adhesions from PID or trauma (uterine currettage, myomectomy)
*surgical tx to lyse adhesions, give high dose estrogen to try to grow healthy endometrium
*intrauterine balloon allows for healing of uterine walls
What causes anovulation?
stable estrogen (low or high) - no variation means you don’t go through a normal cycle
How to dx (s/sx) and work up concern for ectopic pregnancy?
s/sx: pain, bleeding, amenorrhea
- serum quantitative b-hCG
- blood type and Rh status (if Rh neg - need to give RhoGAM)
- CBC
- Transvaginal US (show no intrauterine gestational sac)
At what b-hCG level should you be able to see an intrauterine gestational sac?
1500
How to tx unruptured early ectopic pregnancy?
Methotrexate IM to destroy pregnancy tissue (if b-hCG <5000, ectopic mass <3.5 cm, and no cardiac activity)
f/u b-hCG on days 4 and 7 (see fall by day 7) and then weekly until fall to 0
How do you manage a pt with bleeding, pain, and b-hCG that is <1500 and no intrauterine sac?
follow the p-HCG, should double every 2- 3 days and repeat US when the level is higher
*if b-hCG doesn’t maintain this rate or levels off - suggestive of ectopic
How do you manage an unstable ectopic pregnancy?
emergency laparotomy to stop hemorrhage
How to tx unruptured late ectopic pregnancy?
B-hCG >6000, ectopic mass >3.5 cm or cardiac activity
tx with laparoscopy
f/u with serial b-hCGs
How to work up premenstrual syndrome?
have pt do a 3 month diary to tell about symptoms, should be present just before period and resolve at start of menses
b-hCG
How to manage premenstrual syndrome?
mild - reassurance
eliminate coffee and caffeine, exercise, relaxation methods
SSRIs (fluoxetine) when symptoms are present
or
combo OCPs w/ drospirenone (progestin)- Yaz
What are the phases of the menstrual cycle?
follicular (first half) (FSH rises, estrogen rises)
ovulation (LH surge)
luteal (second half) (progesterone rise)
What is the ddx for pelvic mass pre-menopause?
pregnancy
functional ovarian cyst (normal, just large and will resolve)
benign ovarian neoplasm
malignant ovarian neoplasm
How to w/u pelvic mass in the reproductive years?
b-hCG
pelvic US
How to manage a functional ovarian cyst?
f/u exam and US in 6-8 weeks
*will go away on it’s own
When would you NOT expect to see a physiologic ovarian cyst?
if pt is on hormone contraception - should be suppressing FSH and estrogen - so woudl not be creating follicles…etc.
