Q

What are fibroids?

A

Benign tumours of the smooth muscle of the uterus that are oestrogen sensitive (grow in response to oestrogen)

Also called uterine leiomyomas

Q

What are the types of fibroids?

A
  • Intramural: within myometrium
  • Subserosal: just below outer layer of uterus (grow outwards)
  • Submucosal: just below lining of uterus
  • Pedunculated: on a stalk

Q

What is uterine artery embolisation?

A
  • Catheter inserted into femoral artery, then passed through to uterine artery
  • Once in correct place, particles injected that cause a blockage in the arterial supply to the fibroid: starves it of oxygen causing it to shrink

Q

What medications may be used before fibroid surgery?

A

GnRH agonists e.g. goserelin/leuprorelin
* Used to reduce size of fibroid before surgery by reducing the amount of oestrogen maintaining the fibroid
* Usually only used short-term

Q

What are possible causes of ischaemia in red degeneration of fibroids?

Q

What are the two types of functional cysts?

A

Follicular cysts (MC):
* Occur when follicle fails to rupture and release egg
* Harmless & tend to disappear after a few cycles
* Typically have thin walls & no internal structures = give reassuring appearance on USS

Corpus luteum cysts:
* Occur when corpus luteum fails to break down & instead fills with fluid
* May cause pelvic discomfort/pain/delayed period
* Often seen in early pregnancy

Q

What are some other types of ovarian cysts (not functional)?

  • Mucinous cystadenoma: same as above but these can become huge & take up lots of space in pelvis/abdomen
  • Endometrioma: lumps of endometrial tissue within ovary (occurs in endometriosis), can cause pain & disrupt ovulation
  • Dermoid cysts/Germ cell tumours: benign ovarian tumours, teratomas (come from germ cells & may contain various tissue types e.g. skin, teeth, hair, bone), associated w/ ovarian torsion
  • Sex Cord-stromal tumours: rare, can be benign or malignantm, arise from stroma or sex cords, several types - includes Sertoli-Leydig cell tumours & granulosa cell tumours

Q

What is the pathophysiology of ovarian torsion?

A
  • Usually due to ovarian mass >5cm / normal ovaries in younger girls before menarche (longer infundibulopelvic ligaments that can twist more easily)
  • Twisting of adnexa & blood supply to ovary = ischaemia
  • If torsion persists = necrosis = function lost

Q

How does HPV cause cervical cancer?

A
  • P53 & pRb = tumour suppressor genes
  • HPV produces two proteins: E6 and E7
  • E6 inhibits p53
  • E7 inhibits pRb
  • Therefore HPV promotes development of cancer by inhibiting tumour suppressor genes

Q

What is the cervical intraepithelial neoplasia (CIN) grading system?

A

  • CIN is diagnosed at colposcopy (NOT with cervical screening)

Grades are:

* CIN II - moderate dysplasia
* CIN III - severe dysplasia / cervical carcinoma in situ

Q

What is involved in cervical cancer screening?

A

Aims to pick up precancerous changes in epithelial cells of cervix
* Smear test: speculum exam & collection of cells from cervix
* Cells deposited into preservation fluid & transported to lab for microscopy to check for dyskaryosis (precancerous cervical cells)
* Samples initially tested for high-risk HPV before cells are examined: if HPV negative, the cells are not examined = smear considered negative

Q

What happens during colposcopy?

A
  • Inserting speculum & using colposcope to magnify cervix (allows epithelial lining of cervix to be examined)
  • Acetic acid / iodine solution stains used
  • Acetic acid = abnormal cells appear white (“acetowhite”): occurs in cells with more nucleic material e.g. cervical cancer cells
  • Schiller’s iodine test = healthy cells appear brown, abnormal areas don’t stain
  • To get tissue sample = punch biopsy/large loop excision of the transformational zone (loop biopsy)

Q

What is a cone biopsy?

Risks include:
* pain

Complete mole:
* two sperm cells fertilise an ‘empty ovum’ (contains no genetic material)
* These sperm combine genetic material - cells start to divide & grow into a tumour
* No fetal material will form

Partial mole:

A
  • More severe morning sickness
  • Vaginal bleeding
  • Increased enlargement of uterus
  • Abnormally high hCG

A

American Society of Reproductive Medicine (ASRM)

110
Q

What is the pathophysiology behind pelvic pain in endometriosis?

Pelvic pain = Main Sx

A
  • Cells of endometrial tissue outside uterus respond to hormones in same way as tissue inside the uterus
  • During menstruation endometrial tissue in uterus sheds lining & bleeds - same happens in endometrial tissue elsewhere in body
  • This causes irritation & inflammation of tissues around sites of endometriosis
  • Results in cyclical, dull, heavy/burning pain that occurs during menstruation
111
Q

How does endometriosis cause adhesions?

A
  • Localised bleeding & inflammation - causes damage and deveopment of scar tissue that binds organs together

Q

How does insulin resistance occur in PCOS

A

Insulin resistance is both a symptom and a driver for PCOS

-Insulin resistance means pancreas has to produce more insulin to get the same response

-insulin also promotes androgen release e.g testosterone + suppresses sex hormone binding globulin which usually suppresses androgens

Q

What is the physiology of menopause

A

begins with a decline in the development of the ovarian follicles.

Without the growth of follicles, causes reduced production of oestrogen.

Oestrogen has negative feedback effect on the pituitary gland, suppressing the quantity of LH and FSH produced.

As the level of oestrogen falls in the perimenopausal period, there is an absence of negative feedback on the pituitary gland, and increasing levels of LH and FSH.

Leads to irregular menstrual cycles
