Q

Describe the workup for secondary amenorrhea.

A
  1. serum B-hCG to rule out pregnancy
  2. check TSH with follow up free T4 if abnormal
  3. check prolactin level and get an MRI head if elevated
  4. check FSH and look for symptoms of primary ovarian insufficiency if elevated
  5. check estradiol if FSH is low or normal, if estradiol is low, get a pituitary MRI for hypogonadotropic hypogonadism
  6. check testosterone or look for clinical hyperandrogegism suggestive of PCOS
  7. perform a progesterone withdrawal test; bleeding is indicative of anovulation
  8. if there is no bleeding, perform an estrogen-progesterone challenge test
    > no bleeding suggests an outflow tract obstruction and a hysteroscopy or hysterosalpingogram should be performed
    > bleeding suggests an estrogen deficiency and a pituitary MRI should be done for hypogonadotropic hypogonadism

  • in any woman over 45
  • in any woman under 45 with risk factors
  • in any woman with atypical glandular cells on Pap
47
Q

Why does anovulation lead to abnormal uterine bleeding?

A
  • the ovary produces estrogen but no corpus luteum forms so there is no progesterone and no progesterone withdrawal, which would normally induce menses
  • instead, bleeding occurs only when the endometrial lining outgrows the blood supply and destabilizes
48
Q

What is the treatment for anovulation?

A

must start a LARG or OCP to oppose estrogen or induce menses in order to prevent endometrial cancer

49
Q

What does the differential diagnosis for abnormal uterine bleeding include?

A

PALM-COEIN

  • polyp
  • adenomyosis
  • leiomyoma
  • malignancy/hyperplasia
  • coagulopathy
  • ovarian dysfunction
  • endometrial
  • iatrogenic/infection
  • not yet classified
50
Q

How is an endometrial polyp diagnosed?

A
  • it can be visualized with transvaginal ultrasound of hysteroscopy
  • polypectomy must be performed to confirm the diagnosis
51
Q

If a patient presents with secondary dysmenorrhea, what exam findings would be consistent with:

  • endometriosis
  • adenomyosis
  • leiomyomata
  • adhesions
A
  • endometriosis: painful nodules in the posterior cul-de-sac and restricted uterine motion
  • adenomyosis: an enlarged, boggy-feeling uterus
  • leiomyomata: a rubbery, solid, consistency to an irregularly contoured uterus
  • adhesions: restricted uterine motion
52
Q

Describe the presentation, diagnosis, and treatment for adenomyosis.

A
  • presents with dysmenorrhea and menorrhagia; on exam the uterus is large, globular, and boggy
  • MRI is the most accurate test although it is a clinical diagnosis
  • hysterectomy is the only definitive treatment
53
Q

Describe the presentation, diagnosis, and treatment of leiomyoma.

A
  • presents with heavy, irregular menstrual bleeding, pelvic pain, and pelvic pressure; exam reveals an enlarged, mobile, irregular, and non-tender uterus
  • the diagnosis is made by transvaginal ultrasound, but this may not visualize submucosal myomas, which may require saline infusion sonography or hysteroscopy
  • treat with hormonal contraceptives, myomectomy, or hysterectomy
54
Q

Describe the presentation, diagnosis, and treatment of endometriosis.

A
  • presents with progressive, cyclic dysmenorrhea, dyspareunia with deep penetration, and abnormal bleeding
  • diagnosis can only be confirmed with direct visualization and biopsy via laparoscopy
  • medical management involves NSAIDs, hormonal contraceptives, the androgen derivative danazol, GnRH agonists like leuprolide, and aromatase inhibitors
  • surgical treatment can be used for patients with severe symptoms or who are finished with child bearing
55
Q

Describe the diagnosis and management for PCOS.

A
  • the diagnosis is made when 2 of the following are present: irregular menses or amenorrhea, evidence of hyperandrogegism, and polycystic ovaries seen on ultrasound
  • the diagnosis is also supported by an LH:FSH of more than 3:1
  • treatment starts with weight loss; use OCPs for patients not wishing to conceive; use clomiphene and metformin for those who wish to
56
Q

Why is obesity a risk factor for endometrial hyperplasia and carcinoma?

A

the most common cause of these conditions is unopposed estrogen and adipose tissue has aromatase, which converts androgens to estrogens

57
Q

What is the histologic difference between endometrial hyperplasia with and without atypia?

A
  • without atypia is simply a proliferative endometrium with dilated and contoured glands
  • with atypia is characterized by an increased gland to storm ratio and the presence of atypical cells
58
Q

What are the risk factors for endometrial carcinoma?

A
  • obesity and history of PCOS
  • tamoxifen therapy
  • early menarche and late menopause
  • Lynch syndrome
59
Q

How are endometrial hyperplasia with and without atypia managed?

A
  • without atypia has a lower risk for malignant conversion, so surveillance, progestin therapy, and hysterectomy are all options
  • with atypia, the risk is high so hysterectomy is the treatment of choice
