GP: Women's health Flashcards
Definition of menopause, perimenopause, primary ovarian insufficiency
Menopause: permanent cessation of ovarian function (average at 51y age)- absence of menstruation for 12 mo
Perimenopause: beginning of cycle irregularity thorugh until menopause
POI: menopause <40
Sx of menopause
‘When menopause hits, I’ll have sex not babies’
Weight Mood changes Hot flushes Insomnia Headache Sexual dysfunction + vaginal sx Night sweats Breast tenderness + bones
First line HRT
- Combined E+P patch
- E patch/gel + oral P/LNG-IUD
- Oral E + oral P/LNG-IUD
- Tibilone (synthetic steroid, can be used for sexual dysfunction particularly)
- E + SERM
- Review at 6-8wks
SERM/Progesterone not needed if woman is post hysterectomy
Risks of HRT
- Increased risk of VTE, CVD, stroke
- Gallbladder disease
- Breast cancer
Contraindications to HRT
- High VTE/thrombophilia risk
- Undiagnosed genital bleeding
- Severe active liver disease
- Untreated HTN
- Oestrogen dependent cancer
- Age >60 years or 10y post menopause (not absolute contraindication)
Non hormonal treatment of vasomotor symptoms
- SSRIs
- Clonidine
- Gabapentin, pregabalin
- CBT, hypnosis
- Weight loss
Diagnosing osteoporosis
Minimal trauma fracture or T score
Secondary causes of osteoporosis
Cushing's syndrome Malabsorption e.g., coeliac disease Inflammatory arthritis e.g., rheumatoid arthritis Amenorrhoea > 6 months aged < 45 years Eating disorders Male hypogonadism Chronic liver disease Chronic renal disease Hyperthyroidism Primary hyperparathyroidism Multiple myeloma HIV Medications: Glucocorticoids > 5 mg prednisolone / day for > 3 months Phenytoin Depo-medroxyprogesterone - although associated with a reduction in bone density, this effect normally reverses a year after stopping the drug. In younger women, without other major risk factors for osteoporosis, monitoring of bone density is not recommended. Pioglitazone, rosiglitazone Proton pump inhibitors Gonadotropin‑releasing hormone antagonists Anti-coagulants Aromatase inhibitors
Signs of crush fracture: clinical and imaging
o Back pain
o ↓in height
o Dowager’s hump- kyphosis due to thoracic vertebrae crush fractures
- Wall- occiput test for thoracic fracture
o X-ray: wedge shape
- Anterior height must be 20% less than posterior height
Non-pharmacological treatment of osteoporosis
- Adequate calcium and vitamin D
- Smoking and alcohol intake modification
- Combination of weight-bearing, balance and strength exercise
Pharmacological management of osteoporosis
- Bisphosphonates- bind to hydroxyapatite binding sites to block osteoclasts
- Denosumab (antibody against RANKL)- inhibits osteoclast formation and differentiation
- Raloxifene: SERM (only prevents vertebral fractures)
- Teriparatide: synthetic PTH
- HRT: if significant menopausal symptoms + osteoporosis
Bisphosphonates: risk factors and examples
- dental check before use- rare risk of osteonecrosis of the jaw (also seen in denosumab)
- Atypical femoral fractures
- Avoid in renal impairment
Examples: risedronate (daily tablet)
Zoledronic acid infusion (once yearly)
