Q

how would you investigate postmenopausal bleeding?

Bimanual exam
Speculum (+ smear if not already done)

o 4mm or less = normal
o Multiple bleeds or thickened endometrium:

Endometrial biopsy + hysteroscopy

(bcos tvus will not give histological diagnosis)

A

Combined HRT increases risk Breast Ca , if used for 5 years+ (combined therpay with progesterone not estrogen only)

Oral HRT increases risk of VTE 2-fold
Oral HRT increases gallbladder disease

Oestrogenic: breast tenderness, nausea, headaches

Progestogenic: fluid retention, mood swings, depression

19
Q

A

For vasomotor sx:
Clonidine (alpha-adrenoceptor agonist)
SSRIs
Gabapentin

Vaginal atrophy:
Lubricants and moisturisers OTC

Osteoporosis:
Bisphosphonate - alendronate - stops resorption
SERM - raloxifene. reduces fracture risk
Calcum + vit d supplements - if insufficiency
Lifestyle advice eg regular exercise

20
Q

If BMI > 30, oestrogen only HRT should be given as ____?

A

transdermal patch rather than oral!

21
Q

a woman has undergone an endometrial ablative technique such as transcervical resection of endometrium (TCRE).

which hrt can she have?

A

combined: estrogen + PROGESTERONE

as not all the endometrium may have been removed.

Taken sequentially:

A. Last 2 weeks every month -> monthly bleeds

23
Q

Real case i saw Rapid access clinic with miss Abdi:

42 y/o woman present with 9 month hx continuous bleeding. often spotting, not very heavy bleeding. uses panty liners.
She has a pmh of breast cancer. she has undergone radiotherapy and is now on tamoxifen.
Her period have stopped/become very irregular since starting tamoxifen 3 years ago.

How would you ivx and manage this case?

A

This is technically postmenopausal bleeding as her periods have stopped for 3 years.

Bimanual
Speculum

Lucky she has a TVUS done the previous week so:

pipelle biopsy of endometrium was done with speculum

Hysteroscopy was booked.

remember tamoxifen can put her at risk of endometrial hyperplasia and cancer

24
Q

What is tamoxifen? what effects does it have in breast and endometrium?

A

It is a selective estrogen receptor modulator aka as an anti-estrogen

it acts as an antagonist in breast tissue - so is used in ER+ breast cancers but

it acts as partial agonist on the endometrium so increases risk of endometrial cancer

25
Q

how would you manage vulvovaginal atrophy / symptoms in menopause?

A

mild symptoms:
Topical oestrogen’s - come in many forms :

  1. ring inserted into vagina - lasts 3 months (minimal work) - oestraDiol
  2. creams and pessary - oestriol

severe symptoms:
1. oral tablet eg ospemifene a SERM

26
Q

topical estrogens improve which symptoms of menopause?

A

Vaginal dryness,
soreness, superficial dyspareunia,

urinary frequency and urgency

all respond well to oestrogens, which may be
given either topically or systemically or both together

27
Q

how long do estrogens take to improve vasomotor sx?

A

Oestrogen is effective in treating

hot flushes, usually within 4 weeks.

28
Q

a woman has a T score of -1.5. since taking hrt, t has improe to -1. she has been on hrt for 5 years now, so it is time to stop. 5 months since stopping, her T score is -2. what should she do?

A

we know hrt is protective agaisnt osteoporosis

stopping hrt reaults in a drop in bone density

swithc to other options eg bisphosphonates. but shouldnt restart HRT.

29
Q

what are contraindications to HRT?

A

Hx of Breast, Ovarian, Endometrial cancer

Hx blood clots; dvt, pulm emboli

Hx Liver disease

Hx untreated hypertension - control b4 starting hrt

Pregnant

30
Q

A 48 year old woman comes with vasomotor symptoms. her last period was 12 months ago. Her BMI is 36. what are her risks?

A

sounds like she is menopausal

BUT since she is under 50, she will need contraception for 2 years (1 year left for her).

so you can give her HRT for her sx BUT she will need contraception as well because HRT does not protect from pregnancy.

Can give Mirena coil + patch estrogen - 2 birds with 1 stone.

remember cant give oral estrogen in HRT when BMI is >30

31
Q

which hrt wont increase your risk of breeast cancer?

A

vaginal oestrogen

32

indications?

A

Synthetic steroid compound

its metabolites have estrogenic, progestogenic and androgenic actions

may not be as effective as HRT and is

only suitable for women who had their last period more than 1 year ago

34
