Female and Male GU/Repro Flashcards
1
Q
epithelia of ovary
A
- simple
- cuboidal
- (aka germinal)
- rapidly proliferate to repair ovulatory surface defects
2
Q
epithelia of fallopian tube
A
- simple
- columnar
- ciliated cells transport egg/embryo
- damage can cause infertility, hydrosalpinx, ectopic pregnancy
3
Q
epithelia of uterus
A
- simple
- columnar
- (aka endometrium)
- stratum FUNCTIONALIS sloughs off d/r menstruation
- prolonged estrogen exposure prevents shedding, resulting in hyperplasia/malignancy
4
Q
epithelia of cervix
A
- ECTO-cervix:
- stratified
- squamous
- NON-keratinized
- ENDO-cervix:
- simple
- columnar
- cervical glans secrete mucus:
- thin and watery during ovulation
- mucus plug during pregnancy
- HPV infection predisposed to cervical malignancy
5
Q
epithelia of vagina
A
- stratified
- squamous
- NON-keratinized
- maintains acidic environment to prevent infection
6
Q
Endometriosis
A
- imp c/o chronic pain an dinfertility
- d/t endometrial cells implanted on various pelvic organs (mc:)
- ovary
- posterior cul-de-sac
- broad ligaments
- uterosacral ligaments
- histoL
- hemosiderin deposits
- endometrial glands or stroma outside the uterus
7
Q
Granulosa cell tumor of the ovary
A
- Clinical features:
- large unilat adnexal mass
- INC estrogen
- can present w/ endometrial hyperplasia
- precocious puberty
- INC inhibin
- Histo:
- Call-Exner bodies
- cuboidal granulosa cells
- rosette pattern
- coffee bean nuclei
- ylw theca cells with lipid
- Call-Exner bodies
8
Q
AFP (alpha-fetoprotein)
A
- normally produced by fetal liver and yolk sac
- tumor marker in pts with:
- hepatocellular ca
- NON-seminomatous testicular ca
- ovarian ca
9
Q
beta-hCG
A
- confirm pregnancy
- screen for:
- gestational trophoblastic dz
- germ cell tumors
10
Q
CA-125 (cancer antigen)
A
- elevated in epithelial carcinomas of the ovary
- serous
- endometriod
- clear cell
- stromal tumors do NOT release significant amounts of CA-125
11
Q
Sertoli-Leydif tumors
A
- type of ovarian sex cord tumor
- produces testosterone
- affected pts CP: evidence of HYPER-androgenism:
- hirsutism
- clitoromegaly
- deepening voice
12
Q
Struma ovarii
A
- germ cell tumor of the ovary
- can cause hyperthyroidism by secreting THYROXINE
- histopath: mature thyroid tissue
13
Q
septic abortion
A
- RF: pregnancy ermination with retaine dproducts of conception
- micro:
- gram neg bacilli
- S. aureus and E coli d/t seeding of the uterine cavity d/r instrumentation
- CP:
- fevers, chils, lower abdo pain, bloody or purulent vaginal discahrge
- boggy and tender uterus with dilated cervix
- pelvic US:
- retained products of conception
- INC vascularity
- echogenic material in the cavity
- thick endometrial stripe
14
Q
GnRH
A
pulsatile
15
Q
FSH…FGS
A
- FSH:
- granulosa (FEMALE)
- have aromatase
- location of androgen to estrogen
- sertoli (MALE)
- makes Inhibin B
- granulosa (FEMALE)
16
Q
LH…LTL
A
- Theca (interna) {FEMALE}
- cholesterol to androgens (and progesterone)
- Leydig {MALE}
- Testosterone
- neg feedback on LH and GnRH
- Testosterone
17
Q
FP vs. LS
A
- follicular/Proliferative
- first few days: menses
- primary, secondary, vesicular (surge of estradiol)
- LH and FSH surge at DAY 14
- —-crossover—-
- luteal/secretory
- corpus luteum-secretes progesterone
- regression
- corpus albicans
- making home for embryonic implantation (matures lining)
- spiral arterial coil
18
Q
ovary–E–LH
A
- FSH stimulates ovary (in menopause INC FSH)
- ovary stimulates estrogen release
- estrogen stimulates LH surge (similar to hCG)
- dominant follicle will RUPTURE
19
Q
progesterone withdrawal
A
- INC prostaglandins=vasocontriction of spiral arteries
- INC metalloproteases
- APOPTOSIS
- degeneration of functionalis later
- menstrual flow
20
Q
prolactin and menses
A
anovulation (lactational amenorrhea)
