- increased cardiovascular risk

Psychological and social effects:
- infertility
- feeling of inadequacy as a woman

Progesterone level below 30nmol/L

6

What is a non-specific marker for ovarian carcinoma??

CA-125

7

Typical presentations of fibroids

- menorrhagia
- abdominal mass
- pressure effect from pressure on the bladder, stomach or bowel
- infertility

8

What advice should you give after LLETZ procedure

- patient may have light bleeding for several days
- if heavy bleeding occurs, should return as secondary infection may occur and need treatment
- avoid sexual intercourse and tampon use for 4 weeks, to allow healing of the cervix
- fertility is generally unaffected by the procedure, though cervical stenosis leading to infertility has been reported. Mid-trimester loss from cervical weakness is rare

9

After LLETZ, when should the follow up smears be?

6 months, and then yearly smears for 10 years

10

What is dysfunctional uterine bleeding?

Excessive heavy, prolonged or frequent bleeding that is not due to pregnancy or any recognisable pelvic or systemic disease

11

What should always be measured in a woman with amenorrhoea?

Prolactin

May have a pituitary adenoma (prolactinoma).

NB levels up to 1000mu/L can be found as a result of stress, breast examination or PCOS. Above 1000mu/L is usually a pituitary adenoma

12

DDx of secondary amenorrhoea

Hypothalamic
- chronic illness

- excessive exercise
- stress
Pituitary
- hyperprolactinaemia (drugs, tumour)
- hypothyroidism

Ovarian
- PCOS
- premature ovarian failure
- iatrogenic (chemo/radiotherapy, oophorectomy)
- long-acting progesterone contraception
Uterine
- pregnancy
- Asherman's syndrome
- cervical stenosis

13

Causes of post-menopausal bleeding

PMB is considered to be caused by endometrial cancer until proven otherwise.
Others:
- endometrial/endocervical polyp
- endometrial hyperplasia
- atrophic vaginitis
- iatrogenic (anticoagulants, intrauterine device, HRT)
- infective (vaginal candidiasis)

14

Causes of dysmenorrhoea

- idiopathic
- premenstural syndrome
- pelvic inflammatory disease
- endometriosis
- adenomyosis
- subcostal pedunculated fibroids
- iatrogenic (e.g. intrauterine contraceptive device, or cervical stenosis after LLETZ

15

DDx of postcoital bleeding in a young woman

- cervical ectropion
- chlamydia or other STIs
- cervical maligancy
- complication of the COCP
- endocervical polyp

16

What consists of an STI screen?

- endocervical swab for chlamydia - 30 secs
- endocervical swab for gonorrhoea
- high vaginal swab for trichomonas (and candida)

17

Diagnosis of antiphospholipid syndrome

Presence of one of the clinical features:
- three or more consecutive miscarriages
- mid-trimester fetal loss
- severe early-onset pre-eclampsia, IUGR or abruption
- arterial or venous thrombosis
AND haematological features:
- anticardiolipin antibody or lupus anticoagulant detected on two occasions at least 6 weeks apart

18

What is antiphospholipid syndrome often secondary to?

Systemic lupus erythematosus (SLE)

19

What is the management of antiphospholipid syndrome?

Oral low dose aspirin and low-molecular-weight subcutaneous heparin from the time of a +ve pregnancy test, to improve the likelihood of a successful live birth

20

Causes of recurrent miscarriage

- parental chromosome abnormality
- antiphospholipid syndrome
- other thrombophilia (e.g. activated protein C resistance)
- uterine abnormality (intracavity fibroids, uterine septum)
- uncontrolled diabetes or hypothyroidism
- bacterial vaginosis (usually associated with second-trimester loss)
- cervical weakness ('incompetence', second-trimester loss only

21

How is prolapse categorised?

According to the level of descent of the cervix in relation to the introitus

22

What are the degrees of prolapse?

First degree: descent within the vagina
Second degree: descent to the introitus
Third degree: descent of the cervix outside the vagina
Procidentia: complete eversion of the vagina outside the introitus

23

Management of hypovolaemic shock with hypokalaemia?

- supportive management
- monitor electrolytes
- fluid restriction
- potassium supplementation
- ECG monitoring until K+ is normal
- HDU and oxygen
- monitor ABG

24

What should PMB be considered to be?

Endometrial carcinoma until proven otherwise

25

Risk factors of endometrial carcinoma?

- T2DM
- obesity
- nulliparity

26

Management of endometrial carcinoma?

- simple total abdominal hysterectomy and bilateral salpingoophorectomy
- 90% present in early stage

27

Stages of endometrial cancer:

histologically staged
- stage 1: confined to the body of the uterus
1a limited to endometrium
1b invasion only of the inner half of the myometrium
1c invasion to the outer half of the myometrium
- stage 2: involving the uterus and cervix only
- stage 3: extending beyond the uterus but not beyond the true pelvis
- stage 4: extending beyond the true pelvis into the bladder or rectum

28

What is the true pelvis?

pelvic inlet

29

Prognosis of endometrial carcinoma?

What is Fitz-Hugh-Curtis syndrome?

The presence of perihepatic adhesions in association with previous chlamydial or gonoccocal infection

31

How do you manage pelvic adhesions?

- laparoscopic adhesiolysis
- pain management: analgesics or possible uterosacral nerve ablation
- treat both partners for course of abx in case still infected

32

What are the long term complications of PID?

- chronic pain
- infertility - tubal
- ectopic pregnancy

nb can still have spontaneous pregnancy so stay on contraception if you don't wanna get pregger

33

How is Turner's syndrome managed?

Psychological etc family counselling ... etc
Medical:
- human growth hormone to achieve full height potential
- oestrogen therapy with ethinyl estradiol to enable secondary sexual characteristics (breasts and pubic and axillary hair)
- cyclical progestrogens added later to induce withdrawal bleed (period) for social reasons and to protect endometrium from hyperplasia or malignancy in long run
- oestrogen therapy until menopause age to prevent early-onset osteoporosis
Fertility:
- options available with ovum donation and hormonal support

34

DDx of irregular bleeding with COCP if examination is normal

- poor compliance
- concurrent antibiotics
