How is menorrhagia managed if no contraception is wanted ?
-> Tranexamic acid (if no associated pain)
-> Mefenamic acid (if associated pain)
How is menorrhagia managed if contraception is wanted ?
- 1st : mirena coil
- 2nd : combined oral contraceptivepill
- 3rd : cyclical oral progestogens
- 4th : progesterone only pill or implant
- Final : endometrial ablation and hysterectomy
Give 6 possible causes of menorrhagia
- Dysfunctional uterine bleeding
- Fibroids
- PID
- Anticoagulation
- Bleeding disorders (e.g. VWD).
- Contraception (especially copper coil).
Define adenomyosis
Endometrial tissue within the myometrium
Who does adenomyosis usually effect?
- Multiparous women in later reproductive years
What are the symptoms of adenomyosis ?
Menorrhagia
Dysmenorrhoea
Dyspareunia
What is felt on examination in adenomyosis ?
Enlarged, tender , boggy uterus
What is the first line investigation for adenomyosis
Transvaginal USS
How is adenomyosis managed
- Hormonal / non hormonal management of menorrhagia
- GnRH agonists
- Uterine artery embolisation
- Hysterectomy = definitive
what is adenomyosis associated with in pregnancy ?(8)
Infertility
Miscarriage
Preterm birth
Small for gestational age
Preterm premature rupture of membranes
Malpresentation
Need for caesarean section
Postpartum haemorrhage
Explain puberty in girls
- Occurs between 8-14
- Breast buds, pubic hair and finally menstruation
Define primary ammenorrhoea
Not starting menstruation by :
- 13 years when there is no other evidence of pubertal development
- 15 years of age where there are other signs of puberty, such as breast bud development
- How can causes of primary ammenorrhea be classified
- Hypogonadotropic hypogonadism -> LH and FSH deficiency
- Hypergonadotropic hypogonadism - > lack of response of the ovaries to LH and FSH
- CAH
- Androgen insensitivity syndrome
- Structural pathology
Give 6 causes of hypogonadotropic hypogonadism
- Hypopituitarism
- Damage to hypothalamus / pituitary (radiotherapy, surgery etc)
- Significant chronic conditions (CF/IBD)
- Excessive exercise or anorexia
- Endocrine disorders : GH deficiency, hypothyroid, cushing’s, hyperprolactinaemia
- Kallman syndrome (+ reduced / absent sense of smell)
Give 3 causes of hypergonadotropic hypogonadism
- Turner’s syndrome (XO)
- Congenital absence of the ovaries
- Previous damage to the gonads
Give 3 other causes of primary ammenorrhoea
- Congenital adrenal hyperplasia
- Androgen insensitivity syndrome
- Structural pathology : imperforate hymen, transverse vaginal septae, vaginal agenesis, absent uterus, FGM
what investigations are done to assess primary ammenorrhoea
INITIAL Ix FOR UNDERLYING CONDITIONS
- FBC, U&E’s , coeliac screen
HORMONAL BLOOD TESTS
- FSH and LH
- Thyroid function tests
- IGF-1 for GH deficiency
- Prolactin
- Testosterone : raised in PCOS, CAH and androgen insensitivity syndrome
GENETIC TESTING
- Microarray for turner’s
Define secondary amenorrhoea
No menstruation for >3mnths after previous regular menstrual periods
Give 8 causes of secondary amenorrhoea
- Pregnancy
- Menopause and premature ovarian failure
- Hormonal contraception
- Hypothalamic or pituitary pathology
- PCOS
- Asherman’s syndrome
-Thyroid pathology - Hyperprolactinaemia
Give 4 hypothalamic causes of secondary amenorrhoea
The hypothalamus reduces GnRH in response to stress = hypogonadotropic hypogonadism
- Excessive exercise (e.g. athletes)
- Low body weight and eating disorders
- Chronic disease
- Psychological stress
Give 2 pituitary causes of secondary amenorrhoea
- Pituitary tumours, such as a prolactin-secreting prolactinoma
- Pituitary failure due to trauma, radiotherapy, surgery or Sheehan syndrome
Why does hyperprolactinaemia cause secondary amenorrhoea
- Prolactin acts on the hypothalamus to reduce GnRH.
- No GnRH -> reduced LH and FSH -> hypogonadotropic hypogonadism
What is the most common cause of hyperprolactinaemia
Pituitary adenoma secreting prolactin
What can be used for the treatment of hyperprolactinaemia if necessary
- Dopamine agonists : bromocriptine, cabergoline
