Q

Criteria for PMDD

A
  • PMDD is a psychiatric diagnosis, describing a severe form of premenstrual syndrome
  • diagnostic criteria include five out of 11 clearly defined symptoms, functional impairment
  • prospective charting of symptoms present during the last week of the luteal phase that begin to resolve with the beginning of the follicular phase
  • All three areas of symptoms need to be represented for the diagnosis of PMDD.

Q

Source of estrogen in postmenopausal women

A
  • Estrogen production by the ovaries does not continue beyond menopause.
  • estrogen levels in postmenopausal women can be significant due to the extraglandular conversion of androstenedione and testosterone to estrogen
  • This conversion occurs in peripheral fat cells and, thus, body weight has been directly correlated with circulating levels of estrone and estradiol.
  • Since menopausal ovaries are known to continue production of androgens, surgical removal of postmenopausal ovaries may result in the resurgence of menopausal symptoms from the abrupt drop in circulating androgens.

Q

Characteristifs of Postpartum telogen effluvium (hair loss)

A
  • affects 40-50% of women postpartum
  • High estrogen levels in pregnancy increase the synchrony of hair growth (hair growth normally asynchronous)
  • ==> hair grows in the same phase and is shed at the same time.
  • ==> significant postpartum hair loss at 1 to 5 months postpartum

Q

Tx of urge incontinence

A
  • urge incontinence = detrusor instability
  • acetylcholine is the transmitter that stimulates the bladder to contract through muscarinic receptors
  • Thus, anticholinergics are the mainstay of pharmacologic treatment

    • aFP = low
    • B-hCG = low
    • estriol = low
    • inhibin = normal
  • Trisomy 21
    • aFP = low
    • B-hCG = high
    • estriol = low
    • inhibin = low
  • NTD/abd wall defect
    • aFP = high
    • all others normal
22
Q

Causes of asymmetric fetal growth restriction

A
  • generally, maternal factors ==> asymmetric
    • vascular dz (hypertension, pre-e)
    • antiphospholipid ab
    • autoimmune dz
    • cyanotic cardiac dz
    • substance abuse (tobacco, alcohol, cocaine)

Q

AUB approach in older women/approaching menopause

A
  • ==> endometrial biopsy to rule out endometrial carcinoma
  • hyperplasia w/out atypia ==> progestin therapy
  • hyperplasia w/atypia
    • considering future pregnancy ==> progestin therapy
