Q

Sx for ovarian cyst

A

Mostly aSx but can present with:
1. Pelvic pain (acute pelvic pain usually occurs if there is ovarian torsion, haemorrhage or rupture)
2. Abdominal fullness - early satiety
3. Palpable pelvic mass
4. Bloating

Q

What are the two types of most common functional ovarian cysts?

A
  1. Follicular cysts: MC
    Cysts grow on ovaries = called follicles → release oestrogen and progesterone → release egg during ovulation → monthly growing follicle = functional cyst
  2. Corpus luteum cysts:
    Doesn’t breakdown during menstrual period + gets filled with fluid - commonly occurs in early pregnancy

Q

Describe management for ovarian cysts in premenopausal and postmenopausal women

A

Premenopausal:
If acute pain consider ovarian torsion
<5 cm = Resolves on it’s own
5-7 cm = Yearly USS
>7 cm = MRI scan to rule out cancer

Postmenopausal:
Raised CA125 = 2 week cancer referral

Q

How does insulin resistance occur in PCOS?

A

Insulin = increases androgen levels and suppresses SHBG (sex hormone-binding globulin = binds to androgens)

Therefore, inc. insulin in blood = inc. androgen and decreased SHBG which also further increases androgens+ stops follicle development in ovaries therefore anovulation occurs

Q

Why is there a risk of endometrial cancer in patients with PCOS and how would you manage it?

A

PCOS → no ovulation → dec. progesterone and inc. oestrogen → endometrial lining proliferate without regular shedding → endometrial hyperplasia (abnormal thickening of endometrium) → inc. cancer risk

Tx: Mirena coil or induce bleeding using cyclical progestogens or COCP - helps with endometrial hyperplasia

Describe what is meant by the 2 types of molar pregnancies:
1. Complete mole
2. Partial mole

A
  1. Formation from a single sperm and an empty egg (no genetic material). Thus sperm replicates to provide normal number of chromosomes.
  2. Formed from 2 sperm and normal egg. Both maternal/paternal genetic material is present w/ variable evidence of foetal parts
101
Q

Sx of molar pregnancy?

A

Vaginal bleeding
Nausea
Hyperemesis gravidarum
Thyrotoxicosis (hCG is closely related to TSH)
Uterus larger than expected size for gestational age (due to excessive growth of trophoblasts and retained blood)

102
Q

~~~

Ix for molar pregnancy

A

B-hCG levels - significantly higher than normal preggo

Trans-vaginal USS - in complete molar preggo may show ‘snowstorm’ appearance + absence of foetus

103
Q

Tx of molar pregnancy

A

Not viable preggo - suction curettage to remove them from uterus

If fertility preservation not concern - hysterectomy

Surveillance - bimonthly serum and urine hCG until levels are normal:
* In partial - hCG done 4 weeks later and discharged if normal
* In complete - monthly repeat hCG sent for atleast 6 mths

104
Q

Difference between primary and secondary amenorrhoea?

A
  • Primary - when pt has never developed periods
  • Secondary - when pt previously had periods but subsequently stopped
105
Q

Causes of primary amenorrhoea?

A
  • Hypogonadotropic hypogonadism (abnormal hypothalamus or pituitary gland)
  • Hypergonadotropic hypogonadism (abnormal gonads)
  • Imperforate hymen
106
Q

Causes of secondary amenorrhoea? (4)

A
  • Pregnancy MC
  • Menopause
  • Physiological stress
  • PCOS
  • Medications such as contraceptives
  • Excessive prolactin (prolactinoma)
  • Cushing’s syndrome
107
Q

What is intermenstrual bleeding and give examples of causes of it?

A

Any bleeding that occurs between menstrual periods.

Causes:
* Hormonal contraception
* STI
* Endometrial polyps or cancer
* Cervical polys or cancer
* Vaginal cancer
* Preggo
* Ovulation

108
Q

Causes of dysmenorrhoea? (3)

A
  • Endometriosis or adenomyosis
  • Fibroids
  • PID
  • Copper coil
  • Cancer (cervical or ovarian)
109
Q

Postcoital bleeding causes? (2)

Remember PCB is a red flag

A

Cancers!! (cervical, endometrial and vaginal)
Trauma
Atrophic vaginits
Polyps

110
Q

What is androgen sensitivity syndrome?

A

Cdtn where cells are unable to respond to androgen hormones due to lack of androgen receptors.

111
Q

What kind of genetic mutation is androgen insensitivity syndrome?

Extra androgens are converted into oestrogen resulting in female secondary sexual characteristics (testicular feminisation syndrome)

A

X-linked recessive

112
Q

Describe pathophysiology of androgen insensitivity syndrome?

A
  1. Pts are genetically male
  2. Absent response to testosterone leads to coversion of additional androgens (testosterone) to oestrogen
  3. This result in female phenotype externally and pt have normal female external genitalia and breast tissue
  4. Pts have testes in abdo but don’t develop uterus, upper vagina, cervix, fallopian tubes and ovaries. It also results in lack of pubic hair, facial hair and male type muscle development. They are infertile
113
Q

Which hormone do testes produce which prevents males from developing an upper vagina, uterus, cervix and fallopian tubes?

A

Anti-Müllerian hormone

114
Q

Describe presentation of androgen insensitivity syndrome in infancy and the hormone test results.

A

Infancy: Inguinal hernia containing testes

Hormone tests:
* Raised LH
* Normal/raised FSH
* Normal/raised testosterone levels (for a male)
* Raised oestrogen levels (for a male)

115
Q

Mx of androgen insensitivity syndrome

A
  • Bilateral orchidectomy (removal of the testes) - avoid testicular tumours
  • Oestrogen therapy
  • Vaginal dilators or vaginal surgery - create adequate vaginal length

Generally, patients are raised as female, but this is sensitive and tailored to the individual.

116
Q

Why do males not develop a uterus?

A

Due to anti-Mullerian hormone.

117
Q

Which structure in the fetus does the upper vagina, cdrvix, uterus and fallopian tubes develop from?

A

Mullerian ducts

118
Q

What is an imperforate hymen and what complication can it lead to?

A

When hymen at vagina entrance is fully formed without opening. If not treated can lead to retrograde menstruation leading to endometriosis.

119
Q

What defines that a women has started menopause and typically at what age does this occur?

A

Permanent cessation of menstruation - at least 12 mths of amenorrhoea in women not on hormonal contraception.

Age: 45-55 yrs

120
Q

What is menopause caused by?

A

Ovarian failure which leads to oestrogen deficiency.

121
Q

Sx of menopause

A

Vasomotor: hot flushes, night sweats

Sexual dysfunction: vaginal dryness, dec. libido, dyspareunia

Psychological: depression, anxiety, mood swings, dec. conc.

122
Q

What Ix are done for menopause?
Also describe the levels of the hormones in menopause.

A
  • Preggo test
  • FSH - if 40-45 yrs

Hormones:
* Oestrogen and progesterone = low
* LH and FSH = high

123
Q

What are the risks associated with having a lack of oestrogen?

A

CVD and stroke
Osteoporosis
Pelvic organ prolapse
Urinary incontinence

124
Q

Mx of menopause

A

Combined HRT:
* Oestrogens - oral, transdermal or topical
* Progestogens - oral, transdermal or intrauterine

Non-hormonal:
* Exercise, avoid triggers: spicy foods, caffiene, smoking
* SSRIs
* CBT
* Vaginal moisturisers

Risks of oral HRT = inc. risks of breast cancer, endometrial cancer (if oestrogen given alone), and venous thromboembolism.

Note: oestrogen only HRT is not suitable for woman with a uterus

125
Q

What are the different types of ovarian cancer?

A
  1. Epithelial ovarian tumours - MC
  2. Germ cell tumours - benign + associated w/ ovarian torsion
  3. Sex cord stromal tumours - rare
126
Q

What is a Krukenberg tumour in relation to ovarian cancer?

A

Metastasis in ovary usually from GI cancer. Has a characteristic “signet-ring” cells on histology.

127
Q

RF for ovarian cancer

A
  • Older age
  • BRCA 1 and 2 genes
  • Inc. ovulations - early onset period, late menopause or dec. pregnancies
  • Obesity
  • Smoking
128
Q

Protective factors for ovarian cancer?

A

Dec. number of ovulations in lifetime:
* COCP
* Breastfeeding
* Preggo

129
Q

Sx of ovarian cancer

A
  • Abdo bloating
  • Early satiety
  • Appetite loss
  • Pelvic pain
  • Urinary sx
  • Wgt loss

130
Q

Ix for ovarian cancer?

A

Blood test: CA-125
Pelvic and abdo USS

131
Q

Tx for ovarian cancer

Combined surgery and chemotherapy

132

A
  • Endometriosis
  • Fibroids
  • Adenomyosis
  • Pelvic infx
  • Liver disease
  • Preggo
