Gynaecology - done Flashcards
What are some differentials for amenorrhoea?
Primary
- Abnormal functioning of the hypothalamus or pituitary gland (hypogonadotrophic hypogonadism)
- Abnormal functioning of the gonads (hypergonadotrophic hypogonadism)
- Imperforate hymen
Secondary
- Pregnancy
- Menopause
- Physiological stress: excessive exercise, low body weight, chronic disease
- Polycystic ovarian syndrome
- Medication e.g. hormonal contraceptives
- Premature ovarian insufficiency (menopause before 40)
- Thyroid hormone abnormalities (hyper or hypothyroid)
- Excessive prolactin from a prolactinoma
- Cushing’s syndrome
What are some causes of irregular mensturation?
- Extremes of reproductive age
- Polycystic ovarian syndrome
- Physiological stress (excessive exercise, low body weight, chronic disease)
- Medication e.g. progesterone only contraception, antidepressants / antipsychotics
- Hormonal imbalances e.g. thyroid abnormalities, Cushing’s syndrome and high prolactin
What can cause intermenstrual bleeding?
- Hormonal contraception
- Cervical ectropion, polyps or cancer
- STI
- Endometrial polyps or cancer
- Pregnancy
- Ovulation (causes spotting)
- Medication SSRIs and anticoagulants
What is dysmenorrhoea?
Painful periods
What are the causes of dysmenorrhoea?
- Primary (no underlying cause)

- Fibroids
- PID
- Copper coil
- Cervical or ovarian cancer
What is menorrhagia?
Heavy menstural bleeds
What causes menorrhagia?
- Dysfunctional uterine bleeding (no identifiable cause)
- Extremes of reproductive age
- Fibroids
- Endometriosis / adenomyosis
- PID
- Copper coil
- Bleeding disorders (Von Willebrand disease)
- Endocrine disorders (diabetes / hypothyroidism)
- Connective tissue disorders
- PCOS
What is post coital bleeding?
- Bleeding after sexual intercourse
What is the cause of post coital bleeding (often no cause is found)
- Cervical cancer, ectropion, infection
- Trauma
- Atrophic vaginitis
- Polyps
- Endometrial cancer
- Vaginal cancer
What are the differentials for pelvic pain?
UTI
Dysmenorrhoea (painful periods)
IBS (irritable bowel syndrome)
Ovarian cysts
Endometriosis
PID
Ectopic pregnancy
Appendicitis
Mittelschmerz (cyclical pain during ovulation)
Pelvic adhesions
Ovarian torsion
What are the differentials for vaginal discharge?
- Bacterial vaginosis
- Candidiasis (thrush)
- Chlamydia
- Gonorrhoea
- Trichomonas vaginalis
- Foreign body
- Cervical ectropion
- Polyps
- Malignancy
- Pregnancy
- Ovulation
- Hormonal contraception
What is pruritus vulvae?
Itching of the vulva and vagina
What can cause pruritus vulvae?
- Irritants e.g. soap, detergents and barrier contraception
- Atrophic vaginitis
- Infections e.g. candidiasis (thrush) and pubic lice
- Eczema
- Vulval malignancy
- Pregnancy related vaginal discharge
- Urinary or faecal incontinence
- Stress
What is the definition of primary amenorrhoea?
Not starting mensturation:
- By 13 when there is no other evidence of pubertal development
- By 15 if there are other signs of puberty e.g. breast bud development
When does puberty begin in boys and girls respectively?
8-14 in girls
9-15 in boys
How long does puberty take?
About 4 years
What is the progression of puberty in girls?
- Breast bud development
- Pubic hair development
- Menstural periods (about 2 years from onset)
What is hypogonadism?
Lack of sex hormones (oestrogen and testosterone)
What are the two types of hypogonadism?
Hypogonadotrophic hypogonadism (deficiency of LH and FSH)
Hypergonadotrophic hypogonadism (lack of response to LH and FSH by the gonads - testes and ovaries)
What can cause a deficiency of LH and FSH?
Abnormal functioning of the hypothalamus or pituitary gland
What increases the release of LH and FSH from the anterior pituitary?
Gonadotrophin releasing hormone (GnRH)
What can cause hypogonadotrophic hypogonadism?
Hypopituitarism (under production of the pituitary hormones)
Damage to the pituitary gland (surgery or chemotherapy)
Chronic conditions (CF or IBD)
Excessive exercise or dieting
Constitutional delay in growth and development (temporary delay in growth and puberty)
Kallman syndrome
What can cause hypergonadotrophic hypogonadism?
Abnormal functioning of the testes:
- Previous damage to the gonads (e.g. torsion, cancer or infections e.g. mumps)
- Congenital absence of the ovaries
- Turner’s syndrome (XO)
What is Kallman’s syndrome?
Hypogonadotrophic hypogonadism and failure to start puberty
Associated with reduced or absent sense of smell
