25
what causes an increase in normal vaginal dc
– increase in vaginal discharge due to estrogen which makes everything plump and juicy
26
mild itching and dyspareunia and a foul odor after intercourse
what labs do you want
```

33
Patients using HRT who require evaluation
On hormones for 6 months or more and bleeding
Bleeding is irregular, prolonged or heavy
Patients with intact uterus on unopposed estrogen
need endometrial biopsy
34
evaluation of pts on hormones for 6 months or more and bleeding
Yearly endometrial biopsies (preferred)
Transvaginal ultrasound to check endometrial stripe
35
two different stages for treating menopaus
menopause transition (Early)
post menopause (12 months after last mentsraul period)
36
when is HRT not a viable option ?
why?
over the age of 60 or 10 years post menopause
huge risk for cardiovascular or stroke
37
indications for hRT
vasomotor sxs
urogenital atrophy
sx after oophorectomy
AND
prevention of osteoperosis in pts that have failed estrogen tx
38
definite benefits of estrogen (6)
Decreases hot flashes
Improves bone mineral density (BMD)
Decreases fracture risk
Improves sexual function
Improves symptoms of vaginal atrophy
Decreases risk of colon cancer
39
possible benefits
Improves mood, libido
Decreases skin aging
Decreases incontinence
Reduced osteoarthritis
Prevents cataracts
Prevents macular degeneration
Prevents/slows dementia
40
Advantages of using hormones (OCP or IUD):
Prevention of ovarian cancer and endometrial cancer
Reduction of benign breast disease
Decrease dysmenorrhea, menorrhagia and anemia
Improved bone density
Control of erratic vasomotor symptoms
Stabilization of irregular bleeding
41
Reduction of benign breast disease seen with HRT as it relates to fibrocystic and fibroadenomas
30% reduction fibrocystic disease
60% reduction fibroadenomas
42
what type of BC would you want for a pt with hot flashes
OCP
(IUD) is just progesterone good for irregular bleeding
43
when would you switch from oCP to HRT
OCP until age 51 if no contraindications
Can switch without testing
may have some bleeding and some hot flasshes with switch
44
when would you check and FSH in a pt taking OCP to HRT
Check FSH in day 5-7 of pill free week
FSH over 25, probably menopausal
probably just when the pt would want to
45
world health initiative study found that for breast cancer
being overweight caused a greater risk
if on hormones those with breast cancer had more treatable cancer than those that didn't
however if a women does have a estrogen response breast CA they should not be on this
46
if pts have a family hx of breast cancer
want them on hRT for 5 years or less
47
cardiovascular risk form women considering HRT
absolute risk is generally low in newly postmenopausal women, dependent on background rate and risk factors
Must consider other potential risks: DVT, PE, stroke
For many newly menopausal women with moderate to severe symptoms, benefits will outweigh risks
48
biggest risk for CVD with this type of estrogen
oral estrogen
use transdermal
49
Indicated to treat symptomatic patients
Vasomotor, depression/mood lability, genitourinary syndrome, sleep disturbances
Women in their 50’s who are otherwise healthy have very low risks from HRT
Women <60yo or within 10 yrs of menopause and without contraindications or other risk factors are appropriate candidates for HRT
50
How to Prescribe HRT
Use lowest dose possible to achieve symptom relief
Use shortest duration of treatment
Suggest limiting to 5 years
51
suggestion for women taking HRT
transdermal 17-beta estradiol for many women starting MHT
The transdermal route is particularly important in women with hypertriglyceridemia or risk factors for thromboembolism.
52
when should you use topical estrogen?
if atrophy is the only sx
53
what type of progesterone would be used
Recommend micronized progesterone
54
what to say to the pt that is interested in identical hormones
not FDA regulated
| no evidence
55
mammography is indicated for women
age 50-75
every 2 years
family hx of breast cancer probably higher
56
