Overview• Menstruation and hormones• Pregnancy Pathology (eclampsia, moles)• Sex Chromosome disorders• Psuedo-Hermaphrodites• Questions
GnRH (pulsatile)
FSH
LH surgeFollicles grow
hCG preggo
Menses Vocab
• Oligomenorrhea = infrequent period• Polymenorrhea = period all the time• Amenorrhea = no period at all
• Menorrhagia = heavy flow• Metrorrhagia = frequent and irregular period• Menometrorrhagia = heavy, frequent, & irreg
“Doc, I haven’t had my period in months!
PREGNANCY TEST!
If negative, consider…• 1o Amenorrhea (Never had period)• 2o Amenorrhea (Had it, but now it’s gone)
• Hypothalamus Anorexia, weight loss/exercise
• Pituitary Prolactinoma, Psych Drugs (DA), Hypothyroidism (TRH), Sheehan’s
• Ovaries PCOS*, Premature ovarian failure, Turner’s, Menopause
• Uterus Adhesions (Asherman’s), Mullerian Agenesis
• Vagina Imperforate hymen
Boards PCOS
Clinical: Overweight, hirsutism, amenorrheic, insulin resistance, infertilityLabs: High LH/FSH ratio, high testosterone (cycle of estrogen aromatization in peripheryImages: Polycystic ovariesTx: Stimulate ovulation to regulate hormones. COCP, GnRH agonist pulsatile, Clompihene
Pregnancy Pathology• Moles – Big uterus, hCG, “snowstorm” “cluster of grapes”
• Pre-eclampsia – HTN (140/90, 160/110), proteinuria 3+/5+, seizures– Tx: Deliver baby ASAP
• Placental problems– Placenta Abruptio = detaches, painful bleeding– Placenta Accreta = Adheres to myometrium, bleeds– Placenta Increta = Invades myometrium, bleeds– Placenta Previa = Low-lying placenta
1 egg + 2 spermFetal parts
Empty egg + 1 spermChoriocarcinoma risk (easy chemo tx)Huge uterus
Partial (69XXY) Complete (46XY)
Gyn Onc and Breast
• Ovarian tumors– Teratoma in young women– Serous epithelial in older women – There is no screening test!
• Breast pathology– Fibroadenoma in young women (rubbery, mobile)– Fibrocystic change in middle age women (cyclic)– Invasive CA dimples (Cooper’s ligament, in ducts)– Nipple discharge: Galactorrhea ok, bloody not ok!– Mastitis in breastfeeding (give Abx and continue feeding)
Sex Chromosome Disorders
• Klinefelter’s (boy who looks like a girl)
– Appearance: Small testes, female hair distr, long/lanky– Genetics: XXY – Hormones: Testost Estrogen FSH and LH
• Turner’s (girl with no period)
Appearance: Short, shield chest, webbed neck, edema– Genetics: XO– Hormones: Estrogen FSH and LH – Complications: Coarctation, bicuspid AV, streak ovary
