Q

medical abortion meds / timeline

A

MIFEPRISTONE + MISOPROSTOL - safe up to 9 wks

  • mifepristone given first (progestin antagonist)
  • misoprostol 24-72 after (prostaglandin analog –> contract)

METHOTREXATE + MISOPROSTOL - safe up to 7 wks

  • methotrexate, misoprostol 3-7 days after

Q

follicular phase

A

Days 1-14 Follicular (Proliferative) Phase

ESTROGEN PREDOMINATES
-pulsatile GnRH from hypothalamus –> inc FSH and LH from pituitary to stimulate ovaries

Ovaries

  • inc FSH causes FOLLICLE AND EGG MATURATION
  • inc LH STIMULATES maturing follicle to MAKE ESTROGEN

Endometrium
-ESTROGEN CAUSES THICKENING (PROLIFERATIVE)

  • ESTROGEN CAUSES NEGATIVE FEEDBACK IN HPO system (hypothalamus-pituitary-ovarian)
  • inc levels of estrogen inhibit hypothalamic GnRH release as well as pituitary release of LH and FSH so no new follicles mature

Q

menstruation

A

First days of Follicular phase

  • if egg not fertilized, the corpus luteum soon deteriorates
  • FALL OF PROGESTERONE AND ESTROGEN
  • endometrium no longer supported –> sloughs
  • negative feedback on GnRH subsides causing inc pulsatile GnRH secretion –> inc FSH and LH wich starts follicle maturation process over

Q

ovulation

A

Days 12-14 (part of follicular phase)

  • inc estrogen being released from mature follicle switches from NEGATIVE –> POSITIVE FEEDBACK on GnRH causing mutual INC ESTROGEN, FSH, LH
  • sudden LH SURGE CAUSES OVULATION

Q

luteal phase

A

Days 14-28 (aka Secretory Phase)

PROGESTERONE PREDOMINATES
-LH surge also causes ruptured follicle to become the CORPUS LUTEUM –> SECRETES PROGESTERONE and estrogen to maintain endometrial lining

If pregnancy occurs:

  • blastocyst keeps the corpus luteum functional (secreting estrogen and progesterone, which keeps endometrium from sloughing)
  • if no implantation, corpus luteum degenerates, leading to steep decreases in estrogen and progesterone –> leads to menstruation

Q

abnormal (dysfunctional) uterine bleeding

A

ABNORMAL FREQ/INTENSITY OF MENSES DUE TO NONORGANIC CAUSES (dx of exclusion)

Etiologies:
CHRONIC ANOVULATION (90%) 
-due to disruption of HPA
-esp w/ EXTREMES OF AGE
-UNOPPOSED ESTROGEN  - w/out ovulation there is no progesterone = unopposed estrogen --> endometrial overgrowth w/ IRREGULAR, UNPREDICTABLE SHEDDING

OVULATORY (10%)
-REGULAR CYCLICAL SHEDDING
+ovulation with prolonged progesterone secretion (due to low estrogen levels) –> inc blood loss from endometrial vessel dilation and prostaglandins

  • dx-
  • DIAGNOSIS OF EXCLUSION - r/o reproductive, systemic, iatrogenic causes (no evid of organic cause and negative pelvic exam)
  • W/U: hormone levels, TV US, endometrial bx if stripe >4mm or women >35y to rule out hyperplasia or CA
  • tx-
  • ACUTE SEVERE BLEEDING –> HIGH DOSE IV ESTROGENS OR HIGH DOSE OCP (reduce as bleeding improves)
  • ANNOVULATORY –> OCP 1ST LINE
  • regulates cycle, thins endometrial lining and reduces flow)
  • progesterone if estrogen c/i; GnRH agonists cause tempory amenorrhea
  • OVULATORY –> OCP, progesterone (orally or IUD), GnRH agonists
  • SURGERY - if no response (hysterectomy definitive), ablation

Q

dysmenorrhea

SECONDARY - DUE TO PELVIC PATHOLOGY

  • tx-
  • NSAIDS 1ST LINE (inhibits prostaglandin-mediated uterine activity) - best to start before onset of sx

  • Breasts no Uterus: MULLERIAN AGENESIS, ANDROGEN INSENSITIVITY

SECONDARY - ABSENCE OF MENSES FOR >3 MO IN PT W/ PREVIOUSLY NORMAL MENSTRUATION
-PREGNANCY MC

-3 Signs of placental separation:
1. gush of blood
2. lengthening of umbilical cord
