Q

AIS

A

androgen insensitivity syndrome

genetically male
testosterone is secreted - target cells lack receptors - no masculizing effects occur

46XY - X linked recessive
lack of androgen receptors
primary amenorrhea with normal breast development
absent uterus, short vagina, +testes present
complete (female external genitalia) vs partial
increase testosterone (to male levels)

tx: remove testes after puberty
estrogen replacement after puberty
gender assignment

20
Q

Secondary Amenorrhea

A

Absence of menstruation for at least 3 cycles in pts who previously had regular menstrual cycles
or 6 months in females with irregular cycles

21
Q

What is the MC cause of secondary amenorrhea?

A

PREGNANCY

ovary (40%)
hypothalamus (35%) 
pituitary (7%) 
uterus (7%) 
other (1%)
22
Q

12 x 28 x 6

A

an example of how you document
12 years age of menarche
28 day cycles
6 days of bleeding

23
Q

What drugs of abuse can decrease GnRH?

A

heroin and methadone

24
Q

What are the initial labs you order for secondary amenorrhea?

A
urine pregnancy test 
TSH 
prolactin 
FSH 
LH 
serum estradiol 
testosterone/DHEA-S (r/o PCOS) 
Pelvic US
25
Q

Progestin withdrawal test

A

Rx Provera 10mg daily for 10 days
estrogen vs ovulation problem –confirms the presence of estrogen

withdrawal bleeding occurs within 2-7 days after completion of meds

you are doing this test for pts with a hx of amenorrhea to determine cause

26
Q

What are the possible results of the progestin challenge?

A

you are doing this test for pts with a hx of amenorrhea

if they bleed after this test then they have normal estrogen levels, normal outflow tract, they are NOT ovulating right

if they don’t have withdrawal bleeding its because they dont have endometrial proliferation d/t estrogen deficiency or outflow tract abnormality

27
Q

Functional hypothalamic amenorrhea

A

no pathology

associated with: 
weight loss 
excessive exercise 
anorexia
stress

Female athlete triad: anorexia, amenorrhea, osteoporosis

tx: manage nutritional status
OCPs

28
Q

What is the treatment for functional hypothalamic amenorrhea?

A

manage nutritional status

OCPS

29
Q

Sheehan Syndrome

A

post partum pituitary necrosis
pituitary cell destruction
severe HTN secondary to massive hemorrhage
pituitary hormones GH, TSH, LH, FSH, ACTH

dx: MRI
Tx: replace pituitary hormones

30
Q

Premature ovarian failure

A

depletion of oocytes <40 y/o
high FST and LH
low estradiol
sx: hot flashes, vaginal dryness

concerns: ischemic heart dz, osteoporosis

tx: HRT
estrogen + progesterone
weight -bearing exercise
calcium and vitamin D supplement

31
Q

Polycystic ovaries

A
hyperandrogenism 
obese; hirsute 
dx: polycystic ovaries on US 
signs of androgen excess (acne, hirsuitism) 
oligomenorrhea/amenorrhea

tx: OCPs
metformin

32
Q

Asherman Syndrome

A

intrauterine adhesions or fibrosis
most commonly secondary to scarring from pregnancy related D and Cs

dx: hysteroscopy
tx: hysteroscopic lysis of adhesions

33
Q

Dysmenorrhea

A

painful menstruation, normally occurring with ovulatory cycles

34
Q

What is the most commonly reported menstrual disorder?

A

dysmenorrhe

35
Q

Primary vs Secondary dymenorrhea

A
Primary: 
prostaglandin -mediated 
pain during first 1-2 days of menses 
assoc with N/V/D
no identifiable pathology 

Secondary:
new onset of pain in older women
endometriosis is MC cause of secondary dysmenorrhea
+ pathology

36
Q

What is the MC cause of secondary dysmenorrhea?

A

endometriosis

37
Q

What is the Ddx of secondary dysmenorrhea?

A
endometriosis 
leiomyoma (fibroids) 
Adenomyosis

UTI
ectopic pregnancy
38
Q

What is the treatment for dysmenorrhea?

A

NSAIDs and OCPs

39
Q

What is the function of OCPs?

A

estrogen -progestin combo
prevents ovulation
reduces endometrial growth
decreases PG production

40
Q

Endometriosis

fixed uterus

42
Q

What is the gold standard dx for endometriosis?

A

laparoscopy

43
Q

What is the treatment for endometriosis?
