Don’t forget to rule out endometrial cancer/hyperplasia, cervical cancer
Ovarian insufficiency
Oral contraceptive use
10
Q
What is the point of doing a pelvic USS
A
can be considered to rule out structural anomalies (e.g., leiomyoma, adnexal mass); allows evaluation of endometrial thickness
11
Q
Endometrial biopsy/Pipelle is used for
A
The patient is > 45 years of age OR
The patient is at high risk for endometrial cancer (risk factors include: age > 35 years, obesity, polycystic ovary syndrome, diabetes mellitus, tamoxifen therapy) or has failed medical management OR
Endometrial thickness is ≥ 4 mm in a postmenopausal patient
12
Q
Acute AUB with haemodynamically stable- bleeding alot out what would you give
A
High-dose conjugated estrogen(High levels of estrogen trigger rapid growth of the endometrium and thereby stop sudden, heavy bleeding from the uterine surface. Conjugated estrogen therapy is contraindicated in women with breast cancer and/or those at a high risk of thrombosis)
1st line
High-dose conjugated estrogen OR
multi-dose regimens of OCs or oral progestins

- Endometrial ablation
- Transcatheter uterine artery embolization
- Hysterectomy: reserved for women who do not respond to any other treatment
16
Q
Why do young girls(age 10-12) have irregular bleeding
A
In girls with acute abnormal uterine bleeding and onset of menarche within the last year, anovulatory bleeding due to immaturity of the hypothalamic-pituitary-gonadal axis should be considered.
17
Q
AUB and the woman wants to preserve fertility, what is the best surgical options
A
Dilation and uterine curettage (D&C) with concomitant hysteroscopy-preserve–> Diagnostic and therapeutic
18
Q

29
Why is CST done every 5 years? are they trying to save money by not doing it every 2 years?
Does HPV equal cancer doc
Grows slowly
The body can get rid of the virus on its own
and looking at the virus itself no the cell changes
age of highest sexual encounters- 25
screening too early--> overtreatment
No having HPV means there is likely pre-cancerous changes that COULD/COULD NOT lead to cancer. Does that make sense?
HPV leads to pre-cancerous changes
30

Choriocarcinoma
Placental-site trophoblastic trauma
32
What is the most common cause of premature menopause
- how do you diagnose the condition
- what is the treatment
Menopause occurring before the age of 40 is considered premature. A common cause of premature menopause is ovarian insufficiency. The diagnosis is confirmed by increased FSH levels occurring after more than three months of amenorrhea in a woman under the age of 40. Treatment involves hormone replacement therapy.
33
How long do you have to stay without a period to confirm menopause
The official date of menopause is the last appearance of menstrual blood, which is determined retroactively after 12 months of amenorrhea
34
Why is obesity a risk factor for endometrial cancer
Causes unopposed oestrogen. Some estrogens are produced by peripheral aromatase conversion of adrenal androgens in adipose tissue.
Hence more oestrogen in the body increased risk of endometrial cancer

Weight gain and bloating
Increased risk of coronary artery disease
36
What happens to Estrogen, progesterone and FSH
↓ Estrogen, ↓ progesterone, ↑↑ FSH
Hyperthyroidism and menopause present similarly. For this reason, serum TSH should be checked in all suspected perimenopausal cases with heat intolerance and disturbed sleep to determine the cause!
37
What are some contraindications for HRT/ERT(estrogen replacement therapy)

ABO incompatibility
105
What diagnostic test can be pre-natal and post-natal to determine HDFN
Prenatal diagnosis
Imaging
Ultrasound: to determine hydrops fetalis

108
What is the life-threatening progression of pre-eclampsia
HELLP syndrome
109
What is the pathophysiology of HTN in pregnancy
Arterial hypertension with systemic vasoconstriction causes placental hypoperfusion → release of vasoactive substances → ↑ maternal blood pressure to ensure sufficient blood supply of the fetus
110
Why is there an increased risk of DVT in HTN in pregnancy
Systemic endothelial dysfunction causes placental hypoperfusion → ↑ placental release of factors → endothelial lesions that lead to microthrombosis
111

122
What are some fetal signs and maternal signs of IUGR
Fetal signs
1) Small for gestational age (or with a birth weight below 10th percentile)
2) Decreased or absent fetal movements
Asymmetrical IUGR: disproportionate growth restriction
The dimensions of the head are normal while the body and limbs are thin and small.
Symmetrical IUGR: global growth restriction
The entire body is proportionally small.
The circumference of the head is proportional to the rest of the fetal body.
↑ Risk of neurologic sequelae
Maternal signs
Mostly asymptomatic
