Q

Incontinence - what is the management of urge incontinence (OAB)?

A
  1. Bladder retraining
  2. Bladder stabilising drugs, 1st line are antimuscarinics - OXYBUTYNIN, TOLTERODINE (both immediate release), DARIFENACIN (once daily prep)
  3. MIRABEGRON (Beta3 agonist) - useful if concern about anticholinergic side effects in frail patients, works by relaxing detrusor and increasing bladder capacity
  4. Surgery - botox, bypass, bladder drill

Q

Incontinence - what is the management for stress incontinence?

A
  1. Pelvic floor training, 8 contractions, 3 times a day, minimum 3 months

Q

Ectopic Pregnancy - when so symptoms usually start to occur?

A

6-8 weeks

If embryo has space to grow, symptoms may present later

17
Q

Ectopic Pregnancy - what are the symptoms?

A

Unilateral lower abdo pain

Amenorrhea

Vaginal bleeding

Shoulder tip pain - blood in peritoneum irritates diaphragm, causing shoulder tip pain

D+V

Pelvic pain

18
Q

Ectopic Pregnancy - what are the investigations?

A

Serum hCG testing

Transvaginal US

Vital signs

19
Q

Ectopic Pregnancy - when would you do expectant management and what does expectant management entail?

A

Expectant management - closely monitor patient over 48h, if B-hCG levels rise again or symptoms manifest -> intervention

You would choose expectant management when:

  1. Size <35mm
  2. Unruptured, aymptomatic
  3. No fetal heartbeat
  4. Serum B-hCG <1,000IU/L
20
Q

Ectopic Pregnancy - when would you do medical management and what does medical management entail?

A

Medical management - Methotrexate

You would do medical management when:

  1. Size <35mm
  2. Unruptured
  3. No fetal heartbeat
  4. Serum B-hCG <1,500IU/L

Can’t do medical management if there is another intrauterine pregnancy

21
Q

Ectopic Pregnancy - when would you do surgical management and what does surgical management entail?

A

Surgical management - salpingectomy, salpingotomy

You do surgical management if:

  1. Size >35mm
  2. Can be ruptured
  3. Pain
  4. Visible fetal heartbeat
  5. Serum B-hCG >1,500IU/L
22

Pain not usually a feature

Cervical os is CLOSED

26
Q

Miscarriage - what are the features of an inevitable miscarriage?

A

Heavy bleeding with clots

Pain

Pregnancy will not continue

Cervical os is OPEN

27
Q

Miscarriage - what are the features of an incomplete miscarriage?

A

Products of conception partially expelled

Vaginal bleeding

Pain

Cervical os is OPEN

28
Q

Miscarriage - what are the features of a complete miscarriage?

A

When all pregnancy tissue has left uterus

Vaginal bleeding may continue for several days

Cramping pain

Cervical os is CLOSED

29
Q

Miscarriage - what are recurrent miscarriages?

A

3 or more consecutive miscarriages

30
Q

Miscarriage - what are some causes of miscarriages?

A

Previous miscarriage
PCOS
Abnormality to cervix, uterus, placenta, foetal development
BV infection

31
Q

A

Maternal age >30

Paternal age >45

Smoking

Uncontrolled DM

Uterine surgery

32
Q

Miscarriage - what is the most common cause of recurrent miscarriages?

A

Antiphospholipid syndrome

33
Q

Miscarriage - what is the clinical presentation?

A

Vaginal bleeding with/without abdo pain

Cervical os big enough to admit 1 finger

Uterine size small for dates

Products of conception being expelled

34
Q

Miscarriage - what is the gold standard investigation? What other investigation should you do?

A

Transvaginal US

Serum hCG - exclude ectopic

35
Q

Miscarriage - what are the three types of management and what do they entail?

A

Expectant management:

  1. Waiting for spontaneous miscarriage
  2. 1ST LINE. involves waiting 7-14 days for miscarriage to complete spontaneously
  3. Unsuccessful - medical or surgical

Medical management:

  1. Vaginal Misoprostol - prostaglandin analogue, binds to myometrial cells, cause strong myometrial contractions to expel tissue
  2. Give antiemetics and pain relief too

Surgical management:
1. Vacuum aspiration (suction curettage)

36
Q

Miscarriage - expectant management is 1st line in miscarriage treatment, unless one or more of 4 factors are present, what are they?

A
  1. Increased risk of bleeding
  2. Previous adverse events in pregnancy
  3. Increased risk from effects of haemorrhage
