3
Q
what is the most common type of ovarian cyst?
A

4
Q
what is a follicular cyst?
A
due to rupture of a non-dominant follicle or failure of atresia in a non-dominant follicle
commonly regress after several menstrual cycles
5
Q
what are the symptoms of a corpus luteum cyst?
A
during menstrual cycle, if a pregnancy does not occur then the corpeus luteum usually breaks down and disappears. If this does not happen - the corpeus luteum may fill with blood or fluid and form a cyst.
6

A
PCOS
7
Q
what are the symptoms of a follicular cyst?

bloods - FSH, LH, TSH, testosterone, SHBG, prolactin
check for impaired glucose tolerance
calculate free andorgen index
look at LH:FSH ratio - should be high
31
what would you expect the testosterone level to be in women with PCOS?
raised

lifestyle - weight loss will significantly improve menstrual regulatiry, insulin resistance and all symptoms
hirstuism and ance -
- trial of COCP
- if no improvement can try spironolactone, flutamide, finasteride under supervision
infertility -
- weight management
- clomifene -> under gynae
- metformin
- gonadotropins
36
which combined oral contraceptives are usually contraindiacted in PCOS?
COCs with 35 micrograms of ethinyloestradiol plus cyproterone acetate preparations should not be considered first line in polycystic ovary syndrome (PCOS) due to adverse effects, including venous thromboembolic risks
37
what investigations should be done for a woman with known PCOS who is presenting with less than one bleed every 3 months or irregular bleeding?
Prescribe a cyclical progestogen (such as medroxyprogesterone 10 mg daily for 14 days) to induce a withdrawal bleed, then refer for a transvaginal ultrasound to assess endometrial thickness.
If endometrial thickening is present (greater than 10 mm) or the endometrium has an unusual appearance, refer for endometrial sampling to exclude endometrial hyperplasia or cancer.
If the endometrium is of normal thickness and appearance, advise treatment to prevent endometrial hyperplasia.

slight increased risk of breast Ca, especially when younger
99
is there are an increased risk of breast ca with sclerosing adenosis?
no
100
what is epithelial hyperplasia?
hyperplasia of the epithelium wtihin the breast - causing increased cellularity of the terminal lobular unit

acute porphyria
117
who usually initiates tamoxifen?
usually initiated in secondary care
but can be monitored in primary care if agreed
118
how do aromatase inhibitors work?
aromatose enzyme converts testosterone to oestrogen
aromatase inhibitors prevent this - reducing the overall amount of oestrogen available to bind to ER positive tumours
119
why are aromatase inhibitors preferred in postmenopausal women?
higher effectiveness rate
cannot be used in pre or perimenopausal women as the ovaries are still producing oestrogen, and will just respond to the low levels of oestrogen by producing more
120
what side effects are caused by aromatase inhibitors?
same as tamoxifen -
PV bleeding
hot flushes
joint and muscle pain
increases risk of VTE and loss of BMD

can aromatase inhibitors ever be used in pre menopausal women?
they can sometimes be used if the ovarian function is supressed with other medications such as goserelin
123
what is a bartholins cyst?
entrance to the bartholin dut becomes blocked, the gland produces mucus which builds up behind the entrance, eventually causing a mass to form
124
management of bartholins cyst?
usually no management needed
can use hot compress
OTC analgeisa
125
risk of bartholins cyst?
can form an abscess
126
how do you manage a bartholins abscess?

what is a cervical ectropion?
On the ectocervix there is a transformation zone where the stratified squamous epithelium meets the columnar epithelium of the cervical canal. Elevated oestrogen levels (ovulatory phase, pregnancy, combined oral contraceptive pill use) result in larger area of columnar epithelium being present on the ectocervix. Columnar cells are thicker and so appear darker in colour.

Subserosal (occupying the muscle of the uterus but protruding to the outside of the uterus)
Intramural (which means solely within the muscle layer of the uterus)
Submucosal (partially or wholly within the cavity of the uterus)
Cervical (arising from part of the cervix or lower part of the uterus)
Broad ligament (occupying the lateral tissues of the uterus)
Pedunculated (on the outside of the uterus but attached to the uterus by a stalk)
163
what is the difference between a polyp and fibroid?
fibroid - smooth muscle tissue arrisng form various layers of the womb
polyp - thinner, made of the endometrial lining
164
management of endometrial polyps?
referral to gynae - needs eploration with hysteroscopy due to associated with endometrial Ca
165
management of endometrial hyperplasia without atypical features?
reassurance - rate of progression to endometrial Ca is 5% in 20 years
treatment with high dose progesterone - first line is IUS, second line is continuous oral progestogen treatment, in the form of medroxyprogesterone (10-20 mg per day) or norethisterone (10-15 mg per day). T
resampling every 6 months until 2 consecutive readings are negative
166
what is the management of atypical endometrial hyperplasia?
total hysterectomy usually advised as high risk for development of endometrial ca
progesterone can be used if want to preserve fertility and then advise hysterectomy after this
167
risk factors for endometrial Ca?
Risk factors
excess oestrogen
nulliparity
early menarche
late menopause
unopposed oestrogen. The addition of a progestogen to oestrogen reduces this risk (e.g. In HRT). The BNF states that the additional risk is eliminated if a progestogen is given continuously
metabolic syndrome
obesity
diabetes mellitus
polycystic ovarian syndrome
tamoxifen
hereditary non-polyposis colorectal carcinoma
168
protective factors for endometrial ca?
multiparity
combined oral contraceptive pill
smoking (the reasons for this are unclear)
169
symptoms of endometrial Ca?
postmenopausal bleeding
pre menopausal women usually develop menorrhagia and IMB
170
investigations for PMB?
any woman > 55 yrs with postmenopausal bleeding - referral for TWR
171
what is the cervical cancer screening in the UK?
smear every 3 years from 25-49yrs
smear every 5 yrs from 50-65yrs
172
what is vaginismus?
Vaginismus is a condition in which involuntary muscle spasm interferes with vaginal intercourse or other penetration of the vagina.
173
what is endometriosis?
Endometriosis is characterized by the growth of endometrium-like tissue outside the uterus.
Endometriotic deposits are most commonly distributed in the pelvis; on the ovaries, peritoneum, uterosacral ligaments, and pouch of Douglas. Extra-pelvic deposits, such as in the bowel and pleural cavity, are rare.
174
how common is endometriosis
About 1 in 10 women of reproductive age in the UK have endometriosis.
175
what is OHSS?
In OHSS, ovarian enlargement with multiple cystic spaces form, and an increase in the permeability of capillaries leads to a fluid shift from the intravascular to the extra-vascular space, which has the potential to result in multiple life-threatening complications including:
Hypovolaemic shock
Acute renal failure
Venous or arterial thromboembolism
176
which medication is first line in infertility in PCOS?
clomifene -selective oestrogen-modulating medication to help induce ovulation in those with anovulatory conditions such as PCOS and is prescribed under supervision from a fertility specialist.
177
symptom of anovulatory cycles
menorrhagia - without ovulation there is no corpus luteum to release progesterone to modualte the thickening of the lining and so there is over thickening of the lining which can be heavy and painful to shed
178
what are the instructions for semen sample testing?
Semen analysis should be performed after a minimum of 3 days and a maximum of 5 days abstinence. The sample needs to be delivered to the lab within 1 hour
179
what causes the symptoms of hyperadrogenism in PCOS?
SHBG is a plasma protein that binds the steroid hormones oestrogen, testosterone, and dihydrotestosterone. Low concentrations of SHBG increase the concentration of unbound, biologically active testosterone and dihydrotestosterone, leading to features of hyperandrogenism associated with PCOS.
180
what is the most common cause of spontaenous recurrent first trimester miscarriage?
antiphospholipid syndrome
