A
Heavy or prolonged menstruation typically lasting longer than 7 days or exceeding 80ml.
14
Q
Young patients have irregular/heavy bleeding because?
A
Their HPA is not well developed and don’t produce FSH LH in the right ratios and up to 90% of cycles after menarche can be anovulatory. The endometrium responds to baseline estrogen which is why a lining builds and then sloughs off.

Advancing age, unopposed estrogen or prolonged use of tamoxifen, obesity, nulliparty, anovulatory conditions
29
Pathogenesis of endometriosis
Ectopic endometrial tissue forms on or beneath pelvic mucosal or serosal surfaces, cyclic hyperplasia and degeneration occur in response to female sex hormones, chronic hemorrhaging leads to formation of fibrotic pelvic adhesions.

Raloxifene? Most important side effect?
Selective estrogen receptor modulalator. Mixed agonsit/antagonist. In breast and vaginal tissue it is antagonist whereas in bone tissue it is agonist. Decreases breast cancer risk. One of the first line Tx for osteoporosis though less effective than bisphosohnates and estrongen. Increased risk for VTE
36
PCOS also known as

Nontrepenomal serologic tests and trepenomal serologic tests
RPR, VDRL, FTA-ABS . In primary syphillis may not have yet formed antibodies against syphillis, therefore, can't detect.
45
What's going on with ovaries in Turner Syndrome?
Ovarian dysgenesis => low estrogen => high FSH
46

the 3Ds - dyspareunia, dysmenorrhea, dyschezia
55
Precocious puberty defined as puberty before the ages of
8 for girls or 9 for boys
56
Precocious puberty can be due to
Central (early activation of HPA axis) - will have high levels of FSH/LH or peripheral reasons (excess adrenal or gonadal production of hormones). Wil lhave low levels of FSH/Lh. Example of peripheral precociosu puberty is CAH.

60
Risk factors for scc vaginal cancer and clear cell adenocarcinoma
1) history of hpv 16 or 18, hx of cervical dysplasia/cancer, cigs 2) in utero exposure to DES
61
Aromatase deficiency. Pathophysiology and presentation?
Rare genetic disorder resulting in lack or poor functioning of enzyme that converts androgens to estrogen. In utero> masculization of mother that resolves after delivery. In the child=> high levels of gestational androgens leading to normal internal genitalia but ambiguous external genitalia. clitoromegaly when excess androgens are present in utero. later in life => delayed puberty, osteoporosis, undetectable circulating estrogen, high concentration of gonadotropins and polycstic ovaries. (high FSH/LH)

76
Causes of premature ovarian failure
Chemotherapy, radiation, autoimmune ovarian failure, Turney's syndrome, fragile X syndrome.
77
What are athe FSH and LH levels like in premature ovarian failure
no folicular development -> no estrogen => elevated FSH AND LH. FSH elevated more because of slwoer clearance from the system
78
Patients with secondary amenorrhea should get
FSH, prolactin and pregnancy test
79
Women with excessive exercise, low caloric intake have amenorrhea due to
Decreased LH and GnRH
80
Syncytiotrophoblast
Outer layer of the trophoblasts. Epithelial covering of the embryonic placental villi which invades the wall of the uterus
81
Role of HCG in pregnancy
HCG secreted by the syncytiotrophoblasts to preserver the CL during pregnancy, so that it can continue to secrete progesteerone until the placenta starts making its own progesterone and takes over. Production of hCG starts around 8 days after fertilization and the levels of hcG doubles every 48 hours
82
Alpha unit of hCG is common with
TSH, FSH, LH. Beta unit is specific to hCG and is the basis of home pregnancy tests.
83
Morning after pill is what?
Levonorgestrol, Works by delaying ovulation
84
Abnormal uterine bleeding definition
Menstrual bleeding with abnormal duration, quality, or schedule
85
Ovarian cyst rupture presentation
Mostly in young women of reproductive age, asymptomatic or develop sharp sudden onset unilateral pain esp after strenuous activity or sex. May have slight bleeding due to drop in hormones after ovarian cyst rupture. Pelvic u/s shows free fluid near the cyst
86
Differential diagnosis for acute pelvic pain
1) Ovarian cyst rupture 2) ovarian torsion 3) ectopic pregnancy 4) mittelschmerz 5) ectopic
87
Ovarian torsion presentation
Acute onset uniliateral abdominal pain, n/v, pelvic u/s with doppler shows enlarged ovary veins with decreased blood flow
88
Initial workup for adnexal mass in postmenopausal woman
Trans vag u/s, CA 125 level. In post menopausal women, elevated CA125 has high sensitivity and specificity.
89
Mgmt of asymptomatic women with adnexal mass
if U/S not concerning and CA125 low, observe patient with periodic U/S. if U/S concerning, or if CA125 elevated, refer to gyn onc
90

93
Most common cystic ovarian neoplasm
Serous cystadenomas, accounts for 30% of ovarian tumors. 25% are malignant, about half are bilateral. Do not produce androgens or estrogens.
94
Presenting feature of serous cysteadenoma
Ovarian mass and abdominal pain
95
Granulosa cell tumors. Epi, presenting feature
Fairly common. 10% of all solid malignant ovarian tumors. Tumor produces excess estrogen. Occur at any age but follow bimodal distrubition. If occuring young, will show as precocious puberty (breasts, hair, hyperplasia of uterus). If occuring post menopausal, wont have the tx menopausal sx like vaginal dryness.
96
Dysgerminomas, epi and presentation
Arise in younger women, average incidence age 20. usually unilateral and undergo torsion. Tumor is neutral and does not secrete male or female sex hormone.
97
Sertoli-Leydig cell tumors presentation
Produce testosterone, causes defeminazation followed by masculinization. Altered body contour, scanty breasts,
98
Mature teratomas aka
Dermoid cysts. Don't produce any hormones
99
Examples of emergency contraceptions and efficacy
1) copper iud - causes inflammation, toxic to ova/sperm (99%) 2) levonorgestral pill - progestin, delays ovulation (85%) 3) ulipristal pill - anti-progestin, delays ovulation (>=85%) 4) OCPs (75%) - progestin, delays ovulation
100
Abnormal uterine bleeding in adolescents typically due to
immature hypothalamus pituitary ovarian axis. Endometrium builds up during anovulatory cycles and if ovulation occurs, heavy menses ensue
101
First line tx for AUB in adolescents
high dose estrogen, high dose OCPs, high does progestin, and if those are contraindicated transexemic acid (antifibrinolytic)
102
Side effects of combined OCPs
Breast tenderness, amenorrhea, bloating, breakthrough bleeding, decreased risk for ovarian and endometrial cancer, increased risk for cervical cancer, VTE, hypertension, liver disorders, elevated triglycerides

When 3 of 4 criteria are met, dx 1) positive whiff test 2) clue cells on wet mount (vaginal epithelial cells with adherent coccobacilli) 3) vaginal pH >4.5 4) thin, gray-white vaginal discharge. ITCHING AND BURNING ARE NOT USUAL. VAGINAL EPITHELIUM/CERVIX NOT INFLAMED
104
Premature ovarian failure
amenorrhea>3 months, high gonadotropin levels, low estrogen in women
105
Obesity is a common cause of amenorrhea
There is anovulation secondary to obesity. Ovaries still producing estrogen, but progesterone not being produced at normal post ovulation levels. Therefore, progesterone withdrawal menses at the end of the cycle do not occur
106
Steroid acne presentation
monomorphous pink papules and absence of comedones. Distributed on face, arms, and extremities.
107
Patients taking metronidazole should avoid?
Alcohol - be cautious against disulfiram like reaction - acetaldehyde accumulates in the blood stream. Flushing, N/V, hypotension.
108
Cervical cancer screening guidelines
No screening under 21 unless immunocompromised, HIV+/SLE. 21-29: cytology every three years, 30-64: cytology every 3 years or cytology+hpv testing every 5 years. 65 and over: no screening if hx of negative screens and not at high risk for cervical cancern pts with hysterectomy/cervix removal: no screening is no hx of high grade precancerous lesions, cervical cancer, DES exposure
109
Fibroids presentation
Irregular uterus, pregnancy difficulties, difficulty conceiving, mass issues (causes constipation, urinary frequency, pelvic pressure/pain), heavy menses with clots
110
Tx of fibroids

116
Most common pelvic tumor found in women
Fibroids
117
Risks and benefits of tamoxifen
SERM. Antagnositic on breast and vaginal tissue but agonist on endometrium, increasing risk for endometrial cancer. Has overall mortality benefit, also decreases risk for osteoporosis by acting as a estrogen recept agonist on osteoclasts, inhibiting bone turnover.
