Diagnosis: USS or Hysteroscopy Management: Polypectomy
27
How is HMB managed?
- Pelvic examination (Speculum,Bimanual) remember to look at cervix - Clotting profile, thyroid function - Pelvic USS - Laparoscopy if endometriosis suspected Management options depend on: Impact on QoL, Underlying pathology, Desire for further fertility etc Endometrial Biopsy for all women aged 44 or above with HMB, refractory to medical treatment
28
What are some treatment options for menstrual disorders?
- Observation & monitoring - Hormones - Hormone containing IUD (Mirena) - Endometrial resection (EMR) - Endometrial ablation (NovaSure etc) - Removal of fibroids or polyps - Hysterectomy
29
What are non hormonal medical treatments available?
Tranexamic acid (antifibrinolytic) reduces blood loss 60% Mefenamic acid (prostaglandin inhibitor) reduces blood loss 30% and pain Both of them are taken at the time of periods, Do not regulate cycles Suitable for those trying to conceive or avoiding hormones
30
What are the hormonal options for medical treatments?
Combined contraceptive pill (COCP)makes periods lighter, regular and less painful LNG IUS and Depo-Provera reduces bleeding – may cause irregular bleeding, some women will be amenorrhoeic Oral progestogens eg Provera10mg Day 5-25 cycle reduce bleeding +regulate Day 15-25 may regulate cycle but does not reduce amount of bleeding
31
What is endometrial ablation - first & second generation?
Permanent destruction of endometrium using different energy sources First generation ablation: under hysteroscopic vision – uses diathermy Second generation ablation: thermal balloon, radio frequency Pre-requisites: Uterine cavity length <11 cm Sub mucous fibroids < 3cm Previous normal endometrial biopsy 60% will have no periods, 85% are satisfied, 15% will have subsequent hysterectomy
32
What is a hysterectomy?
Surgical removal of the uterus - Abdo - Vaginal - Laparoscopic Total hysterectomy=cervix & uterus removed Subtotal hysterectomy=Uterus removed & cervix left
33
What are the risks of hysterectomy?
Infection/DVT/bladder/bowel/vessel injury/altered bladder function/adhesions Guarantees amenorrhea
34
What is a salpingo-oopherectomy and when may it be done?
Removal of fallopian tubes & ovaries Ovaries may be removed with uterus in women with endometriosis or presence of ovarian pathology Disadvantages = immediate menopause – recommended HRT till age 50 Advantages =Reduces risk of subsequent ovarian cancer High risk of menopause in next 2 years even if ovaries conserved due to compromised blood supply
35
What is oligo/amennorhea?
Infrequent, absent or abnormally light menstruation Important to check if its normal to the person
36
PCOS is a metabolic syndrome- How is diagnosis confirmed?
If 2 of 3 criteria met: - Ultrasound appearance of ovary - Biochemical hyperandrogenism - Clinical hyperandrogenism with oligomenorrhoea, hirsutism, acne, infertility and obesity
37
What does PCOS result in?
Oligomenorrhea/amenorrhea
38
How is PCOS managed?
Management includes lifestyle adjustment with aim to achieve normal BMI Symptom based treatment At least 3 withdrawal bleeds required per year to prevent hyperplasia or endometrial protection achieved with either COCP, POP, mirena IUS or norethisterone
39
What is dysfunctional uterine bleeding (DUB)?
Common disorder of excessive uterine bleeding affecting premenopausal woman that is not due to pregnancy or any recognisable uterine or systemic diseases (Exclude common causes PALM COEIN (acronym in revision doc))
40
What is the treatment of DUB?
Conservative/Medical surgical treatment based on severity of sym GnRh analogues could be good bridging for patients who are nearly menopausal and have not responded to or declined other medical treatment and surgical management not desirable. GnRH analogues work as ant estrogen and produce a pseudo menopause . upto 6 month therapy. If further desired by patient and no contraindication, should be given add back HRT till patient confirmed menopausal.

Ovarian insufficiency-oestradiol falls FSH from pituitary rises Still some oestriol from conversion of adrenal androgens in adipose tissue
46
What levels fluctuate in perimenopause?
FSH levels - A one off snapshot premenopausal level does not exclude perimenopause as a cause for symptoms
47

Prem Menopause
55
How can HRT be administered for symptom treatment in menopause?
1/ Local vaginal HRT oestrogen pessary/ring/cream Local effects -minimal systemic absorption Need to use longterm to maintain benefit 2/ Systemic oestrogen transdermal patch /gel or oral Transdermal avoids first pass- less risk VTE a/oestrogen only if no uterus b/oestrogen + progestogen if uterus present progestogen oral , patch or LNG IUS progestogen prevents endometrial hyperplasia from unopposed oestrogen Oestrogen alone can cause endometrial hyperplasia & even cancer
56
How can the combined estrogen (E) & progestogen (P) HRT be administered?
-cyclical combined 14 days E + 14 days E+P expect withdrawal bleed after the P use if there may still be some ovarian function to avoid inconvenience of irregular bleeding -continuous combined 28 days E+P oral/patch expect to be bleed-free ( after 1st 3 months) use if > 1yr after LMP or age 54+
57
How can mirena be used and does it give contraceptive cover?
Any age can use Mirena LNG IUS 5 yrs + daily E and expect to be bleed free NB Mirena + E gives contraceptive cover- other HRT regimes do not Mirena has got enough progesterone to balance E HRT for 5 years Mirena will give contraceptive cover up until age 55
58
What are the contraindications to systemic HRT?
NOT the same as contraindications to combined hormonal contraception- very few CI 1/Current Hormone dependent cancer breast/endometrium 2/ Current active liver disease 3/ Uninvestigated abnormal vaginal bleeding 4/ seek advice if prev VTE, thrombophilia, FH VTE 5/ seek advice if previous breast cancer or BRCA carrier
59
What are some contraindications to vaginal HRT?
Avoid for women taking aromatase inhibitor treatment for breast cancer -but may choose to use if symptoms affecting quality of life. No other CI as minimal systemic absorption
60
What are some other examples of what is used as symptom treatment during menopause?
Selective Estrogen Receptor Modulators (SERMs) E effect on selected organs eg tibolone has E effect on flushes, bones but not endometrium clonidine or SSRI SNRI antidepressants eg venlafaxine NOT recommended for vasomotor symptoms. Frequent side effects & few women benefit phytooestrogen herbs eg red clover/soya hypnotherapy/ exercise / cognitive behavioural therapy Non hormonal lubricants for vaginal dryness Regular eg Replens TM or Pre sex ‘Sylk’ TM SERM’s-still has oestrogenic effect on breast tissue so there is an increased risk of breast cancer
61
What are the benefits and risks of HRT?
Benefit vasomotor local genital symptoms osteoporosis Risk breast Ca if combined HRT ovarian Ca venous thrombosis if oral route CVA if oral route Not affect Alzheimers Not increase CV risks if start before age 60 ie before atherosclerosis develops
62
What are some of the NICE guidance for the use of HRT?
For treatment of severe vasomotor symptoms, review annually For women with premature ovarian insufficiency HRT benefits outweigh risks till age 50 Not as first line for osteoporosis prevention / treatment (bisphosphonates instead) Use vaginal oestrogen if vaginal symptoms No absolute upper age limit or maximum duration of HRT use
63
What is andropause?
Testosterone falls by 1% a year after 30 DHEAS falls Fertility remains No sudden change
64
What is the difference between primary and secondary amenorrhoea?
Primary amenorrhoea: never had a period delayed puberty if >14yrs and no 2ndry sexual characteristics >16 years if 2ndry sexual characteristics Secondary amenorrhoea: has had periods in past but none for 6 months
65
What are some causes of secondary amenorrhoea?
Pregnancy / Breast feeding Contraception related- current use or for 6-9 months after depoprovera Polycystic ovary syndrome Premature ovarian insufficiency
66
What is important to ask in the Hx of secondary amenorrhoea?
Possibility pregnancy Breastfeeding Medicines including contraception incl opiates/antipsychotics/metoclopramide Galactorrhoea /visual change ( prolactin ↑) Acne / hirsutism /voice change ( androgen↑) Weight change Exercise /stress Significant illness
67
What are some examinations and tests done in secondary amenorrhoea?
BMI, Cushingoid Acne Hirsutism Virilised- enlarged clitoris/deep voice Abdominal & bimanual exam ? Pelvic mass- pregnant uterus/ ovarian cyst urine pregnancy test bloods FSH oestradiol ( menopause) prolactin thyroid function testosterone & SHBG – free androgen index 17 hydroxy progesterone ( CAH) pelvic ultrasound- ?polycystic ovaries
68
What results are shown in early menopause?
Low oestradiol & raised FSH
69
How is secondary amenorrhoea managed?
Treat specific cause BMI >20 <30 ideal for ovulation Assume fertile and need contraception unless 2 yrs after confirmed menopause If premature ovarian insufficiency offer HRT till 50 Emotional support incl Daisy network Check for Fragile X relatives may wish testing Need contraception as can ovulate at any time & therefore fall pregnant at any time Fragile X-if male foetus is affected then they may be significantly handicapped
70
How is PCOS diagnosed?
Diagnosis-Need 2 out of 3 of the following: oligo/amenorrhoea androgenic symptoms: excess hair/acne Polycystic ovarian morphology on scan ( ie may have PCOS with normal looking ovaries) (Normal/high oestrogen levels Increased androgens – acne/hirsutism ? Underlying cause is insulin resistance)
71
What causes a risk of endometrial hyperplasia?
If < 4 periods a year ( & not on hormonal contraception ) High/normal oestrogen levels & infrequent withdrawal bleeds – risk of endometrial hyperplasia
72
What can worsen PCOS (multiple cysts just below the surface) symptoms?
Weight gain as decreases SHBG levels so increase free androgen levels Increased free androgen levels means androgenic symptoms will worsen – also less likely to ovulate regularly
73
What is the US definition of polycystic ovaries?
Small peripheral ovarian cysts x 10/0vary or ovarian volume>12cm3 20% women have this on scan but no other features ie not PCO syndrome Multicystic ovaries common in adolescents and not associated with PCOS- don’t diagnose PCOS till late teens
74
How is PCOS managed?
Weight loss/exercise to BMI 20-25 Can help all symptoms Increases SHBG so less free androgens Support & information– Verity patient support group Antiandrogen - combined hormonal contraception if no CI - spironolactone - eflornithine cream reduces facial hair growth Endometrial protection CHC, Mirena IUS Oral provera 10 days every 90 days if no period to cause withdrawal bleed Fertility Rx clomiphene / metformin usually effective for ovulation induction Underlying cause – insulin resistance Metformin- may encourage ovulation but no consistent evidence of benefit for androgenic symptoms or helping weight loss
