Week 7 - Paediatrics (B) and Men & Women's health Flashcards
Outline the range of days for a complete menstrual cycle that is considered normal
21-35 days
Outline the difference between central precocious puberty and peripheral precocious puberty
Central precocious puberty is due to increased GnRH production
Peripheral precocious puberty is due to increased oestrogen or testosterone production (normal GnRH levels)
List a few causes of central precocious puberty
- Idiopathic or constitutional
- Obesity related (levels of leptin)
- CNS lesions
- Gonadotropin-secreting tumours
- Systemic conditions e.g. neurofibromatosis
List a few causes of peripheral precocious puberty
- Ovarian cysts
- Congenital adrenal hyperplasia
- Primary hypothyroidism
- Obesity related (compensatory hyperinsulin-aemia)
- Tumours e.g. ovarian, adrenocortical, leydig-cell
List some causes of delayed onset puberty
- Constitutional delay (most commonly)
- Malnutrition or chronic disease e.g. IBD
- Hypogonadism
Outline the definition of primary amenorrhoea
Absence of menarche either by the age of:
14 if there is the absence of secondary sexual characteristics
16 if there is the presence of secondary sexual characteristics
Outline the definition of secondary amenorrhoea
Cessation of periods for:
6 months if periods previous regular
12 months if periods previous irregular
List some causes of primary amenorrhoea
Anatomical:
- Imperforate hymen
- Vaginal septum (vertical or horizontal)
- No vagina
- No uterus
Genetic:
- Turner’s syndrome (XO)
- Complete androgen insufficiency syndrome (XY)
- GnRH deficiency
Other:
- Constitutional delay
- Pregnancy!
- Hypothalamic failure e.g. malnutrition or weight loss
List some causes of secondary amenorrhoea
Anatomical:
- Cervical stenosis
- Asherman syndrome (intrauterine adhesions)
- Early menopause
- PCOS (main reason)
Endocrine:
- Thyroid disease (both hyper and hypo)
- Pituitary disorders e.g. prolactinoma, pituitary necrosis, drugs affecting pituitary gland
- Functional hypothalamic amenorrhoea (weight loss or excessive exercise)
PLUS physiological:
- Pregnancy!! Or lactational amenorrhoea
- Menopause!!
- Contraception
Outline causes of abnormal intrauterine bleeding (PALM-COEIN)
Structural:
- Polyps
- Adenomyosis
- Leiofibroma (fibroids)
- Malignancy / hyperplasia
Non-structural:
- Coagulopathy
- Ovulatory dysfunction (includes thyroid)
- Endometrial issues
- Iatrogenic
- Not yet classified
State the definition of menopause and what it’s caused by
Menopause is the absence of periods for 12 months, in the absence of any other biological or physiological cause
Cause:
- Failure of follicle development and oestrogen production
Outline the age of which menopause is considered early menopause
Under age of 45
Outline the age of which menopause is considered premature menopause (also called premature ovarian failure)
Under age of 40
Outline the age range of which menopause normally happens
Between ages of 45 and 55 (average 50 years)
State the 4 menopausal stages
- Pre-menopausal - slightly changes to FSH/LH levels
- Peri-menopausal
- Menopausal - ovulation actually stops
- Post-menopausal
Outline what happens during the pre-menopause period, with regards to FSH / LH levels, oestrogen levels and fertility
- Less oestrogen secreted
- FSH / LH levels may rise (due to less oestrogen)
- Reduced fertility, but periods remain similar
Outline what happens during the peri-menopause period
Transition phase
- Follicular phase shortens
- Ovulation early / absent
Outline what happens during the menopause period
Permanent cessation of menstruation - lack of ovulation and follicular development failure
Outline what is meant by the post-menopause period
Period of time after 12 consecutive months of no periods
What hormone do you measure to confirm the menopause
FSH - rises (not oestrogen as that is decreasing)
List some physiological symptoms of the menopause
- Hot flushes / sweating
- Sleep changes / tiredness
- Itching
- Restless limbs
- Mood changes
- Forgetfulness
- Vaginal dryness
- Urinary incontinence (increased risk UTIs)
- Constipation and bloating
Appearance:
- Hair thinning
- Thin / fine skin
- Increased weight
- Voice deepening (thickening vocal cords)
- Breast changes
- Sparse pubic hair and reduced fat of labia
List some long term consequences of low oestrogen (post-menopausal)
- Osteoporosis
- Increased cardiovascular risk
- Alzheimer’s disease
Reduced quality of life
List the different methods of administration of HRT and an advantage and disadvantage for each
Oral
+ cheap and effective
- higher doses required
Patch/transdermally
+ reduces risk of VTE
- more expensive / skin reactions
Vaginal
+ minimal systemic absorption
- only treats vaginal symptoms
Mirena coil
+ provides progesterone aspect
- still need oestrogen aspect
State some conservative and non-hormonal pharmacological measures for women with menopause symptoms
Conservative:
- Wear loose/light clothing
- Regular exercise
- Weight loss
- Reduce stress
- Sleep hygiene measures
- CBT
- Vaginal lubricants / moisturisers
Non-hormonal:
- Clonidine (lowers BP and reduces hot flushes)
- Gabapentin
- SSRIs e.g. Fluoxetine
Outline the order of puberty / secondary sexual characteristics in females
- Breast development
- Pubic hair
- Growth spurt
- Menarche
Outline the order of puberty / secondary sexual characteristics in males
- Testes enlargement
- Pubic hair
- Spermatogenesis
- Growth spurt
