question
age range of menarche
answer
10-16
question
Follicular phase of menstrual cycles - what days? - what hormone increased? - uterine changes?
answer
- days 1-13 - increased FSH -> growth of follicles -> increased estrogen production - rsults in development of straight glands and thin secretions of uterine lining (proliferative phase)
question
Ovulation - what day of cycle? - which hormones spike?
answer
- day 14 - LH and FSH spike -> rupture of ovarian follicle -> release of a mature ovum - rupture follicular cells involute and create the corpus luteum
question
Luteal phase - what days? - what hormone is increased? - uterine changes?
answer
- 15-28 - corpus luteum produes estrogen and progesterone -> endometrial lining develops into thick endometrial glands with thick secretions (secretory phase) - in the absence of implantation the corpus luteum canot be sustained and endometrial lining sloughs off

question
nerves at risk of injury in hysterectomy?
answer
ilioinguinal and iliohypogastric these two nerves exit the spinal column at the 12th vertebral body and pass laterally through the psoas muscle before piercing the transversus abdominus muscle to the anterior abdominal wall. Once at the anterior superior iliac spine, the iliohypogastric nerve courses medially between the internal and external oblique muscles, becoming cutaneous 1 cm superior to the superficial inguinal ring.

question
what condition is danazol often used to treat? what is the MOA?
answer
Danazol exhibits hypoestrogenic, hyperandrogenic effects that cause atrophy of the endometrium, which can alleviate the symptoms of endometriosis. Danazol prevents ovulation by suppressing the increase of luteinizing hormone during the middle of the menstrual cycle. Danazol inhibits ovarian steroidogenesis resulting in decreased secretion of estradiol and may increase androgens. Danazol displaces testosterone from sex hormone-binding globulin (SHBG), displacing it and increasing serum testosterone levels. Danazol also directly stimulates androgen and progesterone receptors.
question
management of endometrial polyps
answer
Management of an endometrial polyp includes the following: observation, medical management with progestin, curettage, surgical removal (polypectomy) via hysteroscopy, and hysterectomy. Observation is not recommended if the polyp is > 1.5 cm. In women with infertility polypectomy is the treatment of choice.

question
what is the clomid challenge test? when is it used and what do the results mean?
answer
A clomiphene challenge test, which consists of giving clomiphene citrate days five to nine of the menstrual cycle and checking FSH levels on day three and day 10, will help determine ovarian reserve A healthy ovary will only require a small level of follicle stimulating hormone (FSH) to produce an egg; whereas, if the ovary is not functioning as well, it will require substantially higher levels of FSH to produce an egg. High levels of FSH are usually a negative indicator of fertility; however, a normal FSH doesn't guarantee egg quality. In essence, an elevated FSH is a poor indicator while a normal FSH is neutral.
question

- reprsents carcinoma in situ with *no underlying carcinoma* - erythematous, pruritic, ulcerated vulvar skin
question
Indications for cervical conization include:
answer
1) unsatisfactory colposcopy, including inability to visualize the entire transformation zone 2) positive endocervical curettage 3) Pap smear indicating adenocarcinoma in situ 4) cervical biopsies that cannot rule out invasive cancer 5) a substantial discrepancy between Pap smear and biopsy results - ex: discrepancy between the HSIL Pap smear result and the normal reading on the biopsies and the ECC, the patient requires a cervical conization such as LEEP or cold knife cone.
question
uterine cancer screening for patients on tamoxifen?
answer
annual exams - do NOT do annual US because tamoxifen causes changes to the endometrium, including thickening.

answer
"painful bladder syndrome" symptoms of suprapubic pelvic and/or genital area pain, dyspareunia, urinary urgency and frequency, and nocturia + *no bacteria isolated*
question
urethritis =
answer
infection of the urethra commonly caused by *c. trachomatis* (+ gonococcus) suspect in women with typical UTI symptoms yet sterile culture and no response to standard abx ==> cultures of urethra for gonoccous and chlaymydia + empiric tx for chlamydia with doxycycline

answer
1. up to 10 week (early preganancies) 2. 7-13 weeks
question
what is the safest of all surgical termination methods in the first trimester?
answer
suctional curretage
question
MOA of mifepristone
answer
synthetic progesterone receptor ANTAGONIST ==> blocks stimulatory effects of progesterone on endometrial growth
question
until how many weeks can medical abortion w/mifepristone + misoprostol be performed?
answer
9 weeks
question
until how many weeks can MTX be used for medical abortion?
answer
7 weeks
question
how to confirm effective of medical abortion afterwards?
answer
must follow up in 2 weeks for US and b-hcg (requires 2 visits = downside compared to surgical)
question
2 options for 2nd trimester abortions? which is the safest?
answer
1. Dilation and evacuation (D&E) = most common and safest method of termination 2. Induction of labor
question
major advantage of induction of labor vs D&E for second trimester abortion
answer
deliver an intact fetus = more comprehensive postmortem evaluation
question
how do OCPs work?
answer
induce pseudopregancy state = prevent release of FSH and LH ==> supresses ovulation and prevents preganncy form occuring
question
disadvantages of depo-provera? (3)
answer
1. irregular menstrual bleeding 2. reversible decrease in bone mineralization 3. significant delay in the return of regular ovulation (6-18 months)
question
disadvantage of nexplanon? (1)
answer
irregular and unpredictable light bleeding
question
progesterone only forms of BC (4)
answer
1. progesteron only mini pill 2. depo provera (injectable) 3. nexplanon 4. mirena IUD
question
3 forms of emergency contraception
answer
1. ECP = levonorgestrel 2. coppper IUD 3. ella (ulipristal aceta = selective progesterone receptor modulator)
question
benign cystic teratoms vs. immature teratoma vs. malignant teratoma - tissue type? - tx?
answer
- 1. benign = ectodermal derivatives (skin, hair follicles, sevaceous/sweat glands) 2. immature = all 3 germ layers + immature embryonal structures 3. malignant = immature neural elements (amount of neural tissue determines grade) - tx of benign cystic teratoma = cystectomy tx of malignant teratoms = unilateral salpingoopherectomy with wide sampling of peritoneal implants ==> combo chemo if grade 2/3
question
which type of ovarian tumor is known to grow to be very large?
answer
mucinous tumors (epithelial) ==> can rutpure intra-abdominally and cause pseuudomyoma peritonei ==> repeated bouts of bowel obstruction
question
presentation of fascial disruption at surgical wound site? tx? what condition predisposes to it?
answer
profuse drainage from the incision 5-14 days after surgery requires repair ASAP w/initiation of broad spectrum abx (surgical emergency) diabetes = a/w increased risk for fascial separation b/c it more difficult for wounds to heal
question
tx of wound evisceration
answer
evisceration = protrusion of bowel or omentum through the incision (complete separation of all layers of the wound) tx = sterile sponge wet with saline should be placed over the bowel ==> surgery and abx
question
superficial wound infection - tx?
answer
- open the wound and drain the purulence + broad spectrum abx + wet-to-dry dressing changes - --> wound can heal by secondary intention
question
endometrial tissue that floats with a "frond pattern" is almost always diagnostic for ____
answer
intrauterine pregnancy - helps rule out ruptured ectopic pregnacy (ectopic pregnancy co-existing with an intrauterine preganncy is exceeding rare)
question
when a woman presents w/signs of hemoperitoneum and ectopic is ruled out (endometrial tissue with frond pattern), what is next most likely diagnosis?
answer
rupture of hemorrhagic corpus luteum cyst - corpus luteum cysts can have intrafollicular bleeding bc of thin walled capillaries that invade the granulosa cells from the theca interna ==> when hemorrhage is excessive, the cyst can enlarge and there is an increased risk of rupture
question
when in pregnancy does corpus luteum stop producing progesterone?
answer
10 weeks
question
1. how to confirm dx of corpus luteum cyst? 2. tx?
answer
1. laparoscopy 2. secure hemostasis, once bleeding stops no further tx is required, but if bleeding conintues a cystectomy should be performed ==> if corpurs lutuem is surgically removed prior to 10-12 weeks must supplement progesterone
question
most common cause of hemoperitoneum in early pregnancy?
answer
ectopic pregnancy
question
first sign of hypovolemia?
answer
oliguria = decreased urine output
question
most common method of diagnosing intrauterine adhesions? how is diagnosed confirmed
answer
hysterosalpingogram confirmed w/hysteroscopy
question
tx for IUA?
answer
operative hysteroscopy (resection of adhesions) post-operative management = insertion of IUD or pediatric foley catheter to prevent the recently lysed adhesions from re-forming + estrogents/progesterone
question
is cervical stenosis or IUA a/w cramping pain every month?
answer
cervical stenosis - due to retrograde menses
question
chancroid
answer
- caused by haemophilus ducreyi - lesions with ragged edges, necrotis base - adenopathy
question
lymphogranuloma venereum
answer
- infeciton of lymphatics caused by C. trachomatis (L1-L3) - PAINLESS primary genital ulcers that heal spontaneously ==> - tendery lymphadenopathy ==> bubos that rupture ==> sinus tracts - rectal stricutres
