Z2F Gynaecology Flashcards
Primary vs secondary amenorrhoea
Primary have never developed periods
3 causes of primary amenorrhoea
Imperformate hymen Abnormal gonads (hypergonadotrophic hypogonadism) Abnormal hypothalamus or P gland (hypogonadotrophic hypogonadism)
Periods should start by
13 if no signs of puberty
15 if signs of puberty
Order of puberty development in girls
Breasts -> pubic hair -> periods
What does kallman syndrome cause
Hypogonadotrophic hypogonadism (lack of FSH and LH)
2 key symptoms of kallman syndrome
Failure to start puberty
Absent sense of smell
Hypogonadotrophic hypogonadism effect on hormones
Low FSH and low LH
Hypergonadotrophic hypogonadism hormone levels
High FSH and LH
Low oestrogen
3 causes of hypergonadotrophic hypogonadism
Injury to gonads (cancer, mumps, torsion)
Congenital aplasia
Turners syndrom (XO)
Does turners syndrome cause Hypo or hypergonadotrophic hypogonadism
Hypergonadotrophic hypogonadism
Hypothalamus still making gnrh and p making FSH and LH
No oestrogen negative feedback
Androgen insensitivity syndrome presentation and cause
Unable to respond to androgens (testosterone)
Female phenotype with no female internal organs but vagina
Cyclical abdominal pain but no menorrhagia: dx
Structual issues
Inperformate hymen/ FGM/ transverse vaginal septum
Antibody test on girls aged 15 without periods
Anti TTG (coeliacs)
Treatment for kallman syndrome
Pulsitile GnRH +/- COOP
High isolated FSH suggests
Primary ovarian failure
High LH isolated suggests
PCOS
How to reduce risk of endometrial cancer in women with PCOS
Induce withdrawal bleed every 3-4 months
Either COOP use or medroxyprogesterone (DEPO as a pill) for 14 days
Other than ca, amenorrhoea associated with low oestrogen is a risk for
Osteoporosis
Treatment for PMS
Lifestyle
COOP - Yasmin/ contains drospierone
SSRI
CBT
Treatment for physical symptoms of PMS after COOP, lifestyle and SSRI tried
Spirolactone
Average menstrual blood loss
40mls
Management of painful heavy periods in women who want to conceive vs non painful
Mefenamic acid (if pain) TXA (if no pain)
Order of management of heavy periods in women who do not want to conceive
Mirena
COOP
Cyclical progesterones
Fibroids are sensitive to which hormone
Oestrogen (shrink after menopause)
4 types of fibroids
Submucosal - just below lining of uterus
Intramural - in myometrium (distort uterus)
Subsersosal - outer layer of uterus (grow into abdo)
Pedunculated - on a stalk
Most common presentation of fibroids
Heavy menstrual bleeding
Fibroids on examination present as
NON tender mass on PV/ abdominal exam
Management of fibroids depends on ??
Size (less than 3cm)
Fibroid less than 3cm the management is same as ??
same as heavy menstural bleeding
Mirena
TXA/ NSAIDS
COOP
Cyclical progesterones
Fibroids greater than 3cm management
refer to gynaecologist
Same as less than 3cm medically
Surgical - ablation, hysterectomy, uterine artery embolisation, myomectomy etc
Only known treatment to improve fertility in women with fibroids
Myomectomy
Myomectomy is used to treat
Fibroids
IN WOMEN WHO CANNOT CONCIEVE - only known treatment
Pregnant women with hx of fibroids presents with abdominal pain and low grade fever :dx
Red degeneration of fibroid (ischaemia due to lack of blood supply)
Red degeneration of fibroids risk factors
Greater than 5mm
2nd and 3rd trimester
Red degeneration of fibroids presentation
Severe abdo pain, low grade fever, tachycardia, vomiting
Chocolate cysts
Endometrial tissue in the ovaries
Adenomyosis
Endometrial tissue in myometrium
Gold standard endometriosis diagnosis
Laparoscopy
Management of endometriosis
NSAIDS COOP (back to back) trial of other hormonal contraception Adhesionlysis Induce menopause like state - GnRH analogues
Adenomyosis is more common in which women
Multiparous and late reproductive years
Adenomyosis symptoms triad:
dysmenorrhoea, menorrhagia, dyspareunia
Adenomyosis on examination
Tender and enlarged uterus
First line investigation for adenomyosis
TVUSS
Treatment for adenomyosis?
Same as menorrhagia
Mirena
TXA/ NSAIDS
COOP
Cyclical progesterones
Effects of adenomyosis on pregnancy
Bad things (same for endometriosis) Infertility, miscarriage, PPROM, preterm labour, PPH
Menopause definition
12 months of amenorrhoea needed for dx but the menopause is the day of the last period
Premature menopause date
Before 40 years
Menopause hormone levels
Low oestrogen and progesterone
High FSH and LH
Low oestrogen and progesteron
High FSH and LH
Indicates what
Menopause
What age do women need to use contraception until
Two years without a period if under 50
One year without a period if over 50
Nice first line test for suspected menopause in under 45s
FSH blood test
COOP UKMEC after 40
UKMEC 2
Contraception that is not as good to use after 40 years
COOP - only UKMEC 2 age
(DEPO cause osteoporosis) shouldn’t use after 45
Max age for DEPO
45 - osteoporosis
Two key side effects of DEPO and unique contraindication
Weight gain, osteoporosis, (delay to fertility)
Over 45s
Average length of perimenopausal symptoms
2-5 years
Unique treatment for reduced libido at menopause
Testosterone cream
Unique treatment for vaginal dryness and atrophy after menopause
Vaginal oestrogen
Premature ovarian insufficiency diagnosis is made by:
Under 40, low oestrogen symptoms, high FSH on two occasions with a 4 week gap
Premature ovarian insufficiency treatment
HRT - important to reduce risk of CVD and OP. Increased risk of breast ca and VTE if used in under 50s but lower BP
OR
COOP - contraception is still possible in POI
Risks of HRT in under 50s in comparison to over 50s
Increased risk of breast ca and VTE if used in under 50s
Which type of HRT: no uterus
Oestrogen only
Which type of HRT: still having periods
Cyclical progesterone and regular break through bleeds
Until 12 months without a period
Which type of HRT: women with a uterus and 12 months without a bleed
Combined
Non HRT, menopausal drug treatment for vasomotor symptoms
Clonidine
CANNOT withdraw suddenly
Key benefits of HRT
Improved QOL
Reduced OP and fracture risk
What type of drug is clonidine
Alpha 2 adrengenic and imidazoline receptor agonist
Clonidine indications
Vasomotor symtom control
?PCOS
HTN
If women wanting HRT still have periods, what type of HRT must they have?
Cyclical HRT (with progesterone)
Cancer risks of HRT
Breast and endometrial
