A

pathophys:

  • transplacental passage of maternal anti-TSH R Ab
  • Ab bind to infants TSH R and cause excessive thyroid hormone release

CF:

  • warm, moist skin; tachy
  • poor feeding, irritability, poor weight gain
  • low birth weight or preterm birth

diagnosis: maternal anti-TSH R Ab >500% nml

40
Q

endometriosis

A
  • can have pelvic pain and/or infertility or be completely asymptomatic
  • tx: saids, ocp, progesterone IUD, leuprolide
41
Q

lactational amenorrhea

A
  • result of high levels of prolactin which has inhibitory effect on the production of the hypothalamic gonadotropin-releasing hormone (GnRH)
  • pulsatile GnRH release from hypothalamus is necessary for the production and release of LH and FSH by the ant pit
  • LH and FSH stimulate the ovary to induce ovulation
  • by inhibiting GnRH (and thus l and f) prolactin prevents ovulation and menstruation
  • because lactation suppresses ovulation it is a natural form of contraception for the first six months postpartum is om is exclusively breastfeeding
42
Q

Bartholin cysts

A
  • soft, mobile, contender masses
  • located at the base of the labia major
  • symptomatic cysts require incision and drainage, followed by Word catheter placement
