Q

Key Points to the menstrual cycle

A

1) Follicular phase/Proliferative (14 days): presence of estrogen thickens the endometrium until a dominant follicle is produced-leads to ovulation
2) Luteal phase/Secretory phase: AFTER ovulation, progesterone prepares uterus lining for implantation, if the corpus leuteum doesn’t implant, then you will decrease both hormones and menstruation happens

Q

What is the cause of primary dysmenorrhea?

A

Non-pelvic etiology:

  • Caused by increased prostaglandin secretions which causes increased uterine wall contractility

Q

Etiologies of primary amenorrhea

A

1) A uterus & breasts present and there is outflow obstruction
2) There is no uterus (Mullein agencies, androgen insensitivity)
3) Ovarian causes of too much FSH, LH-there would be no breasts present (premature ovarian failure, gonadal dysgenesis)
4) HPA axis failure causes low FSH. LH

Q

Amenorrhea workup

A

1) pregnancy test
2) estrogen stimulation

3) Progesterone challenge test
- If withdrawal bleeding there is an ovarian issue
- If no withdrawal bleeding there is not enough estrogen or an outflow obstruction

A

Abnormal placental placement on or close to the cervical os

81
Q

How does placenta previa present?

A

PAINLESS 3rd trimester bleeding, do an u/s to determine placenta placement

-You then need to monitor fetal heart rate and induce steroids for lung development if past 24 weeks. If complete previa you must do C-section

82
Q

A

Premature separation of placenta from uterine wall

83
Q

How does placental abruption present?

Q

Average length of menstrual cycle

85
Q

Etiologies of dysfunctional uterine bleeding

A

1) chronic anovulation (90 %)
- unopposed estrogen without ovulation means no progesterone is produced, which means the uterus will shed irregular and unpredictably as overgrowth occurs rather than when progesterone should have stimulated it to.

2) ovulatory
- Prolonged progesterone secretion after ovulation causes increased endometrial vessel dilation and prostaglandins

86
Q

Workup of dysfunctional uterine bleeding

A

Diagnosis of exclusion!!

-must find no organic cause even after all the following has been evaluated:

Hormone levels, TVUS, endometrial bx (if >4mm)

A
  1. high dose IV estrogens

2. hysterectomy is definitive

Q

Treatment for anovulatory and ovulatory causes of dysfunctional uterine bleeding
