Q

Types of IUCD

A

All levonorgestrel based
Jaydess: 13.5mg LNG, 6ug daily, 3 years
Mirena: 52mg LNG, 20ug daily, 5-8 years
- stops release of egg from ovary
- inhibits sperm from reaching/ fertilising egg
- thins lining of the uterus
- thickens cervical mucus

Q

IUCD insertion and removal in pregnancy

A

If HCG +ve, IUCD should be removed
IF PP, insert after 6/52 to minimise risk of expulsion
Insert immediately after 1st/ 2nd trimester loss

Inc or normal LH (elevated in 40%, usually slim women)
Normal FSH
Inc or normal fasting insulin - not routinely measured; GTT done to screen for insulin resistance

Q

Pathophysiology of PCOS

A

Maybe genetic
Raised ovarian androgens –> multple follicles and PCO appearance
Increased LH –> increased androgen production
Decr SHBG - causing hihghh circulating freeandrogens
- levels inversely proportional to BMI
Insulin augments LH activity –> inc. resistance, incr LH activity –> inc ovarian androgens.

If not eager for cyclical hormones/ oligomenorrhoeic - US for ET every 6-12/12
- ET >10mm –> artificially induce bleed
- mirena for endometrial protection
Metformin 850mg bd - 8% conception rate. Used D2-6. Decreases circulating androgens and improves ovulation in those w BMI >25 and no response to clomid

Management of ovarian cyst

A

- laparotomy : large solid (eg dermoids)
- avoid rupture of spillage
- oophorectomy - discuss preop
- aspiration: less effective and assoc w high rates of recurrence

A

Exaggerated response to circulating levels of BHCG in thhe absence of ovulation –> grossly enlarged ovaries bilaterally; bilateral large theca lutein cysts

57
Q

Assessment of ovarian mass in pregnancy

A

Imaging: USS, colour doppler, MRI/ CT
Tumour markers:

69
Q

Management algorithm uterine fibroids

A

Asymptomatic –> clinical surveillance
Symptomatic –> pre vs postmenopause
- Premenopause:
— enhance fertility: consider removal submucosal fibroids; no proven benefit to removing intramural and subserosal wrt fertility
— retain fertility (AUB): medical rx (ullipristal, OC, danazol, LNG-IUS, TXA, GnRH agonist). OR surgical (myomectomy)
— retain uterus (bulk effects +/- AUB): medical (ullipristal/ SPRM, GnRH agonist +/- add-back) OR surgical (myomectomy)
— other (bulk effects +/- AUB): interventional therapy (UAE, MRg-FUS, myolysis) OR surgical (myomectomy +/- EA)
- Postmenoapuse:
— TAH +/- BSO.
— hysteroscopic myomectomy

A

40-50 yrs: can be continued

When to stop IMP/ POP/ LNG-IUS in peri/post menopausal

A

40-50 yrs: Can be continued to age 50 and beyond
>50: stop at age 55when natural loss of fertility can be assumed for most women
- if wants to stop before 55, check FSH level
- if FSH > 30iU/L - the IMP/ POP/ LNG-IUS can bediscontinued after 1 more year
