Q

What are the CFs of PCOS?

A
  • Menstrual irregularity - oligo/amenorrhoea
  • Hyperandrogenism - acne, hirsuitism
  • Anovulatory infertility - oligo/anovulation
  • Increased risk of pregnancy complications eg. spont abortion, gestational diabetes, pre term labour
  • Insulin resistance - obesity and T2DM, acanthosis nigricans

Q

What is the theorised pathogenesis behind PCOS?

A
  • Genetic link
  • Increased LH and increased LH receptors = increased LH:FSH = excess androgen production
  • Insulin resistance = hyperinsulinaemia to compensate for resistance, stimulates theca cells = increased androgen secretion

Q

Describe the pre ovulatory phase of the menstrual cycle

A
  • Pulsatile GnRH causes FSH and LH release frm the ant pit
  • Follicle grows due to FSH release
  • LH releases androgen which is converted to oestrogen by aromatase = increased O

Q

Describe how ovulation occurs

A

High levels of oestrogen act as positive feedback on FSH and LH - surge of LH causes ovulation, happens at Day 14.

Q

What is the uterus doing around the time of ovulation?

A

From day 11-15 the uterus is preparing for implantation and fertilisation of the egg:
- Spiral arteries grow
- Endometrium thickens
- Cervical mucus thins to allow sperm to pass

Q

What happens in the luteal phase?

A

Corpus luteum continues producing oestrogen but lutenised granulosa cells produce lots and lots of progesterone so it is the dominant hormone.
Progesterone and inhibin -ve feedback LH and FSH causing reduced oestrogen - this signifies ovulation has taken place.

Q

What do high levels of progesterone do to the uterus?

A

Prepares the uterus to thick its cervical mucus = once oocyte fertilised don’t want to let any more sperm through and coil its spiral arteries = once oocyte is fertilised will implant.

Q

What happens in the secretory phase/menstruation?

A

Corpus luteum changes to the corpus albican which is basically dead - no oestrogen or progesterone produced. Spiral arteries collapse and the lining sheds = menstruation.

Q

What bloods are involved in ix PCOS?

A
  • Total testosterone
  • LH (often elevated)/FSH (elevated in premature ovarian failure, differential for PCOS)
  • Prolactin - hyperprolactinaemia can cause oligomenorrhoea
  • Thyroid profile - often causes irreg periods
  • Free androgen index - if raised is diagnostic of PCOS

Q

How do you treat menstrual irreg in PCOS? Why does it need treating?

A

Causes endometrial hyperplasia = possible increased risk endometrial cancer. Therapies prevent endometrial thickening.

Q

How do you treat the metabolic complications of PCOS?

  • Quit smoking
  • Screen for diabetes, dyslipidaemia and HTN
  • Metformin - used to be used but not routinely anymore

What is letrozole and how does it work?

A

Non steroidal aromatase inhibitor - decreases oestrogen produced by body. Used to prevent growth of breast cancers that are oestrogen receptive and induces ovulation. Decreased O = increased FSH = stimulates follicles and aids ovulation.

  • May still be fertile under 50 for 2 years after their last period
  • May still be fertile over 50 for a year after their last period
66
Q

  • Psychological sx - HRT, CBT, antidepressants
67

  • Endometrial biopsy
  • Hysteroscopy and biopsy
  • Transvaginal US
70
Q

What is the management of endometrial hyperplasia?

A
  • Reassure low risk of developing cancer
  • Address RF
  • Watchful waiting
  • Progestogen treatment - IUS, medroxyprogesterone, norethisterone
  • 5 monthly biospies until 2 consecutive biopsies negative
  • Hysterectomy - if change to atypical hyperplasia, relapse, no regression after 1 yr of progestogen
71
Q

What is the management of atypical hyperplasia?

A
  • Total hysterectomy due to risk of malignant progression, w bilat salpingo oophorectomy if you are post menopause
  • If wish to preserve fertility - progestogen options w 3 monthly endometrial biopsy then hysterectomy as soon as no longer need to be fertile
  • 40% of women w atypical hyperplasia have concurrent carcinoma or at significant risk of developing
72
Q

What infections can cause menstrual irregularity and what sx do they cause?

A
  • STIs eg. gonorrhoea and chlamydia cause post coital bleeding
  • Pelvic inflammatory disease
73
Q

What is PID? What are the causes?

A

Pelvic inflam disease - infection spreads from vagina through the cervix and into the upper genital tract. Commonly caused by STIs, most commonly chlamydia but gonorrhoea is increasing.

74
Q

What are the CFs of PID?

A

Sx - bilat abdo pain, purulent discharge, post coital bleeding, deep dyspareunia
Signs - adnexal tenderness (pain in area of the uterus), cervical motion tenderness on bimanual, fever
10% of pt present w RUQ pain - secondary to inflam or the liver capsule = Fitz Hugh Curtis syndrome

75
Q

A
  • Pregnancy test - exclude ectopic pregnancy as a differential
  • Cervical and endocervical swab for gonorrhoea and chlamydia
  • Bloods - FBS, CRP, etc

  • Urinalysis to exclude UTI
76
Q

Q

What are some of the functional ovarian cysts?

A

Ovaries grow small cysts = follicles each month which rupture to release can egg.
- Follicular cyst - when the follicle doesn’t rupture but instead continues to grow
- Corpus luteum cyst - follicle releases the egg and the opening is blocked so fluid builds up = cyst
- Usually harmless and rarely cause pain

83
Q

A
  • Dermoid cyst - teratoma, formed from germ cells that make eggs, can continue tissue eg. hair, skin and teeth
  • Cystadenoma - from cells on surgace of ovary, can be fulled w fluid/mucous material
  • Endometrioma
  • Dermoid cysts and cystadenomas can grow v large and move the ovary out of position, increases the chance of ovarian torsion
