WOMENS EXTRA CONDITIONS Flashcards
1* AMENORRHOEA
What is primary amenorrhoea?
Absence of menstruation by –
- 14y if no secondary sexual characteristics (more indicative of a chromosomal abnormality)
- 16y with secondary sexual characteristics (breast buds)
1* AMENORRHOEA
What is the difference between hypogonadotrophic hypogonadism and hypergonadotrophic hypogonadism?
- Deficiency in gonadotrophins (LH + FSH) stimulating ovaries due to abnormal hypothalamus or pituitary means they do not respond by producing sex hormones (oestrogen)
- Gonads fails to respond to stimulation of gonadotrophins meaning no negative feedback + increasing amounts of FSH/LH
1* AMENORRHOEA
What are some causes of hypogonadotrophic hypogonadism?
- Constitutional delay (temporary delay, no pathology, ?FHx)
- Hypopituitarism
- Kallmann’s (failure to start puberty + anosmia)
- Excessive exercise, dieting or stress causes hypothalamic failure
- Endo = Cushing’s, prolactinoma, thyroid
- Damage (cancer, surgery)
1* AMENORRHOEA
What are some causes of hypergonadotrophic hypogonadism?
- Turner’s syndrome XO
- Congenital absence of ovaries
- Previous damage to gonads (torsion, cancer, infections like mumps)
1* AMENORRHOEA
What are some other causes of primary amenorrhoea and how may they present?
- Congenital adrenal hyperplasia (tall, deep voice, facial hair)
- Androgen insensitivity syndrome (46XY but female phenotype)
- Congenital malformations of genital tract (if ovaries unaffected = secondary sexual characteristics but no menses)
- Gonadal dysgenesis (no ovaries or uterus form)
1* AMENORRHOEA
What are some first line investigations for primary amenorrhoea?
- Examination = signs of puberty, PV exam, BMI, visual fields
- FBC + ferritin (anaemia), U+E for CKD, anti-TTG for coeliac, urinary beta-hCG crucial
1* AMENORRHOEA
What hormonal blood tests would you do for primary amenorrhoea?
- FSH + LH (low or high)
- TFTs, prolactin (if indicated)
- Free androgens raised in PCOS, AIS + CAH
- Insulin-like growth factor I used for screening for GH deficiency
1* AMENORRHOEA
What other investigations may be useful for primary amenorrhoea?
- XR of wrist to assess bone age + Dx constitutional delay
- Pelvic USS for structural causes
- ?MRI head if pituitary
- Karyotyping for Turner’s syndrome, AIS
1* AMENORRHOEA
What is the management of…
i) constitutional delay?
ii) ovarian causes (PCOS, damage/absence of ovaries)
iii) genital tract abnormalities?
iv) pituitary tumour?
v) stress?
i) May only require reassurance + observation
ii) COCP can induce regular menstruation + prevent Sx of oestrogen deficiency
iii) Surgery
iv) Surgery, chemo, radio or bromocriptine if prolactinoma
v) CBT, healthy weight gain, stress reduction
1* AMENORRHOEA
What is the management of hypogonadotrophic hypogonadism?
- Pulsatile GnRH can induce ovulation, menstruation + potentially fertility
- COCP if pregnancy not wanted to replace sex hormones, induce regular menstruation + prevent Sx of oestrogen deficiency
2* AMENORRHOEA
What is secondary amenorrhoea?
What is oligomenorrhoea?
- Previously normal menstruation ceases for >3m in a non-pregnancy woman
- Where menses are >35d apart (up to 6m), can be ovarian normality but exclude PCOS
2* AMENORRHOEA
What are the causes of secondary amenorrhoea?
- Pregnancy (most common), breastfeeding, menopause (physiological)
- Iatrogenic (contraception)
- Hypothalamic/pituitary
- Ovarian causes (PCOS, POI)
- Thyroid, uterine pathology (Asherman’s)
- Excessive exercise, stress or eating disorders
2* AMENORRHOEA
What are the hypothalamic or pituitary causes of secondary amenorrhoea?
- Sheehan’s syndrome = pituitary necrosis following PPH
- Pituitary tumour like prolactinoma leading to hyperprolactinaemia which prevents GnRH
- Trauma, radiotherapy or surgery
2* AMENORRHOEA
How does excessive stress or eating disorders cause secondary amenorrhoea?
- Hypothalamus reduces GnRH in times of stress > hypogonadotrophic hypogonadism to prevent pregnancy in adverse situations
2* AMENORRHOEA
What hormonal tests would you do in secondary amenorrhoea?
- Urine/blood beta-hCG
- High FSH (POI)
- Low FSH/LH (hypgonadotrophic hypogonadism)
- High LH or LH:FSH ratio suggests PCOS
- Free androgen raised in PCOS
- Mid-luteal (day 21) progesterone to check ovulation happened
- Prolactin + TFTs if indicated
2* AMENORRHOEA
What other investigations may you do in secondary amenorrhoea?
- Pelvic USS to Dx PCOS
- MRI head if ?pituitary tumour
2* AMENORRHOEA
What is the management of…
i) hyperprolactinaemia?
ii) hypothalamic failure?
i) Bromocriptine or cabergoline (dopamine agonists)
ii) GnRH replacement
CERVICAL ECTROPION
What is cervical ectropion?
What is it associated with?
- Columnar epithelium of endocervix extends out to ectocervix
- Endocervix cells more fragile so prone to trauma + to bleed (post-coital)
- High oestrogen > young women, COCP, pregnancy
CERVICAL ECTROPION
How does cervical ectropion present?
- Increased vaginal discharge
- Abnormal PV bleeding (IMB + PCB)
CERVICAL ECTROPION
How does cervical ectropion present on speculum?
- Well-demarcated border between redder, velvety columnar epithelium extended from os + pale pink squamous epithelium of ectocervix
- ‘Red ring’ around cervical os (transformation zone)
CERVICAL ECTROPION
What is the management of cervical ectropion?
- Problematic bleeding = cauterisation (silver nitrate or cold coagulation during colposcopy)
POI
What is premature ovarian insufficiency (POI)?
- Premature menopause before the age of 40
POI
What are some causes of POI?
- Majority idiopathic
- Iatrogenic (chemo/radio, oophorectomy)
- Autoimmune (coeliac, T1DM)
- Genetic (FHx, Turner’s)
- Infections (mumps, TB, CMV)
POI
What is the clinical presentation of POI?
- Secondary amenorrhoea (or irregular) + typical peri-menopause Sx before age 40
POI
What are some investigations for POI?
- Clinically = menopausal Sx in woman <40y with 4m of amenorrhoea
- FSH level = >25IU/L on 2 samples >4w apart
- Hypergonadotrophism + hypoestrogenism
POI
What are the complications of POI?
- Higher risk of conditions due to lack of oestrogen > CVD, stroke, osteoporosis, dementia + cognitive impairment + Parkinsonism
POI
What is the management of POI?
- HRT imperative until at least average age of menopause to reduce risks
- HRT or COCP can be used
POI
What is the difference between traditional HRT and COCP in POI?
- Traditional HRT associated with lower BP than COCP
- COCP may be more socially acceptable if younger + acts as contraceptive
POI
Are there the same risks of HRT in POI as in menopause?
- No increase in breast cancer risk as women normally produce these hormones at that age
- Slight increased risk of VTE but reduced by transdermal patch
FGM
What is female genital mutilation (FGM)?
- All procedures involving partial or total removal of female external genitalia or injury to female organs for non-medical reasons, often pre-pubertal
FGM
What is the WHO classification for the types of FGM?
- 1 = partial or total clitoridectomy
- 2 = excision
- 3 = infibulation
- 4 = all other non-medical harmful procedures incl. pricking, piercing, incising
FGM
What is…
i) excision?
ii) infibulation?
i) Partial or total removal of clitoris + labia minora ± excision of labia majora
ii) Narrowing/closing of vaginal orifice with creation of a covering seal (stitch labia together)
FGM
What are some potential reasons for FGM?
Based on customs –
- It will bring status + respect to family (social norm)
- Rite of passage + being part of woman
- Preserves girls’ virginity so acceptable for marriage
- Cleanses + purifies girl with perceived religious requirement
FGM
What are some acute complications of FGM?

- PTSD
FGM
What is the initial management of suspected or confirmed FGM?
- Report ANY FGM in <18 to police + Record in notes (consider in >18 after risk assessment e.g. others at risk like unborn children)
- Educate pts + relatives that FGM is illegal + health consequences
- Services = social, safeguarding, paeds, counselling, FGM specialists
FGM
What is the overall management of FGM?
- De-infibulation by specialist in FGM in some type 3 to try restore function
- Re-infibulation may be requested after childbirth but this is illegal
MACROSOMIA
What is…
i) large for gestational age (LGA)?
ii) macrosomia?
i) Estimated foetal weight above the 90th centile for their gestational age
ii) Baby with a weight >4kg regardless of gestational age
MACROSOMIA

What are some complications of macrosomia?
- Maternal = failure to progress, perineal tears, instrumental/c-section, PPH, uterine rupture (rare)
- Foetal = shoulder dystocia, neonatal hypoglycaemia, obesity in childhood + later life
MACROSOMIA
How do you diagnose and manage macrosomia?
- OGTT to screen for diabetes
- SFH + EFW from USS to plot on growth chart + >90th centile = Dx
- Regular growth scans to assess progress + check amniotic fluid index levels to exclude polyhydramnios
