What is the treatment?
Nabothian cyst (blocked mucinous endocervical glands)
No treatment required (normal variant)
How do estrogen and progesterone influence fibroids?
Estrogen stimulates smooth muscle proliferation.
Progesterone interferes with apoptosis.
What contraceptive method is associated with decreased bone mineral density?
Depot medroxyprogesterone acetate (DMPA)
(However, may regain BMD after stopping and no clear association with increased fractures)
What are the contraindications for progesterone-only contraceptives?
Breast cancer and liver disease
(Unlike combined OCPs, can use in smokers, those with HTN, CAD, or CVD, and those with migraines.
What reliable birth control is a good choice for someone with breast cancer or liver disease?
Copper IUD
What percentage of patients undergoing myomectomy will need repeat surgery for fibroids?
25%
How is the definitive diagnosis for adenomyosis made?
Post-hysterectomy pathology
What presents with heavy, painful menses and an enlarged, “boggy” uterus?
Adenomyosis
What is the treatment for endometrial polyps?
Removal with hysteroscopy or D&C (risk of cancer)
What should the length of the endometrial stripe be in a postmenopausal woman?
What test needs to be done on women with atypical glandular cells on pap smear?
Endometrial biopsy (as well as endocervical curettage I think)
What is the most important factor for cancer risk on endometrial biopsy?
Cellular atypia (complex hyperplasia also a factor, but less important)
(Simple hyperplasia without atypia has 1% chance of progressing to cancer. Complex hyperplasia increases this to 3%, cellular atypia alone increases this to 8%, both together increases wirk to 29%).
In general, how is endometrial hyperplasia without atypia treated? With atypia?
Without atypia: symptom management: continuous progestins, cyclic progestins, or combination OCPs
With atypia: hysterectomy preferred due to high cancer risk, if want to preserve fertility can use high dose progestins and close following

(These are the rarest functional ovarian cysts, result from excessive HCG such as with molar pregnancy or multiple gestations)
What functional ovarian cysts are at risk for hemorrhage?
Corpus luteum cysts
How are cystic adnexal masses managed in reproductive-age women? Postmenopausal women?
Reproductive age: observe if less than 8-10 cm, exploratory laparoscopy/laporatomy for ovarian cystectomy if larger. If smaller cyst persists >90 days, do same procedure.
