Ovulatory dysfunction
Endometrial
Iatrogenic
Not yet specified
What time frame defines chronic AUB
> 6 months
What investigation should be done in all women with AUB and why
FBC to check for anaemia
What further investigations should be arranged for women with heavy menstrual bleeding
Bloods: FBC, TFTs, coagulation studies
Imaging: TVUSS, hysteroscopy ± endometrial biopsy
What is the management for heavy menstrual bleeding
- IUS (not trying to conceive), tranexamic acid or mefenamic acid (NSAID) (trying to conceive)
- COCP
- Progesterone
- surgery
What are uterine polyps and its clinical features
Focal proliferations of the uterine tissue
RF: older age
Asymptomatic, may cause intermenstrual bleeding
Smooth, lobular, friable lump on bimanual
What is adenomyosis and what are its features
Growth of the endometrium in the myometrium
Prolonged, heavy, painful menstrual bleeding
Pelvic pain
Dyspareunia
Subfertility
What features of a gynae history may suggest a coagulopathy
Heavy menstrual bleeding since menarche
Postnatal haemorrhage
Surgery-related bleeding
Bleeding associated with dental work
Frequent and large bruising
Frequent epistaxis or gum bleeding
FHx bleeding symptoms
What are some iatrogenic causes of heavy menstrual bleeding
gonadal hormone use → unscheduled breakthrough bleeding
Anticoagulants
Tamoxifen
IUS/IUD
TCAs, phenothiazines
What are some causes of intermenstrual bleeding
Polyps
Cervical cancer
Endometrial hyperplasia
What are some cause of post-coital bleeding
Cervical ectropion
Polyps
Cervicitis e.g. secondary to chlamydia
Cervical cancer
Vaginal cancer
Trauma
Condylomata accuminata
Vaginitis
What is cervical ectropion and how does it present
Endocervical glandular epithelium expands beyond the os and becomes visible on the ectocervix (squamous) → may be friable
Usually asymptomatic, otherwise post-coital bleeding
Erosions where there is a darker red colour around the external os
What are the risk factors for cervical ectropion
Hormonal contraception use
Pregnancy
Adolescents
What is condylomata accuminata caused by and what is their appearance
HPV infection → genital warts
Verrucous flesy papules that may coalesce into plaques
What are the surgical options for heavy menstrual bleeding
Hysteroscopic polyp removal
Endometrial ablation
Transcervical resection of the endometrium (TCRE)
Second generation techniques involving balloons, microwaves, cryotherapy or radiotherapy.
Transcervical resection of fibroid: for fibroids up to 2cm in diameter
Hysterectomy
