Using result from cervical screening
If positive for HPV 16/18/33 refer to colposcopy to visualise transformation zone and swab it
What is ectropion

Ectropion causes
COCP
Elevated oestrogen (ovulatory phase)
Pregnancy
Dysmenorrhoea
- Def
- Primary vs secondary
- Causes
Pain during menstrual period
Primary: no pelvic pathology, pain few hours pre-period (due to rise in PGs)
Secondary due to:
Endometriosis, adenomyositis, PID, Intruterine device (copper), fibroids
Treating dysmenorrhea
NSAIDs (Mefanic acid & Ibuprofen) - inhibit prostaglandins (thought to be reason)
COCP second line

Menopause
- Def
- Age
- Criteria
Cessation of menstruation due to loss of follicular activity
Average around 51 (perimenopause before this)
12 months from last period in over 50, 24 months if under 51
Menopause symptoms

Vasomotor: Hot flush, night sweats
Urogenital: dryness, atrophy, urinary freq
Psych: anxiety and depression in 10%, short term memory
Osteoporosis, Inc risk IHD
Menopause management
Lifestyle modification
- exercise (mood, cognitive, flushes)
- good sleep hygiene (cog, sleep dist)
