Gynaecology + Obstetrics Flashcards
1
Q
HPV cercial cancer types (1)
other RF (5)
A
Human papillomavirus infection (particularly 16,18 & 33) is by far the most important risk factor
Mechanism of HPV causing cervical cancer
HPV 16 & 18 produces the oncogenes E6 and E7 genes respectively
E6 inhibits the p53 tumour suppressor gene
E7 inhibits RB suppressor gene
Other RF:
smoking, HIV, parity, low SES, COCP
2
Q
widely spaced nipples and primary amenorrhoea
A
Turner’s syndrome
(X)
3
Q
hormonal changes characteristic with turners
A
raised gonadotrophin levels (FSH/LH)
decreased levels of oestrogen and progesterone due to gonadal dysgenesis resulting in a compensatory increase in serum FSH and LH.
Gonadal dysgenesis causes an increase in FSH/LH by the negative feedback cycle to try to compensate for the lack of oestrogen and progesterone produced by the ovaries.
4
Q
Increased serum androgen levels
A
polycystic ovarian syndrome. This will present a history of oligomenorrhoea, obesity, acne and hirsutism.
5
Q
most common cause of primary amenorrhoea
A
gonadal dysgenesis (e.g. turners)
other causes:
testicular feminisation
congenital malformations of the genital tract
functional hypothalamic amenorrhoea (e.g. secondary to anorexia)
congenital adrenal hyperplasia
imperforate hymen
6
Q
secondary amenorrheoa
A
hypothalamic amenorrhoea (e.g. secondary stress, excessive exercise)
polycystic ovarian syndrome (PCOS)
hyperprolactinaemia
premature ovarian failure
thyrotoxicosis*
Sheehan’s syndrome
Asherman’s syndrome (intrauterine adhesions)
7
Q
amenorrheoa- what do the gonatorohins show us
A
FSH/LH tell us:
low levels indicate a hypothalamic cause where as raised levels suggest an ovarian problem (e.g. Premature ovarian failure)
raised if gonadal dysgenesis (e.g. Turner’s syndrome)
8
Q
secondary amenorrhoea + raised FSH/LH + lw oestradiol
A
POremature ovarian insufficiency (<40 years)
9
Q
Gonadotropin-producing pituitary adenoma: hormones
A
elevated FSH and LH levels alongside normal or high oestradiol levels
- mass effect on surrounding structures, such as headaches or visual disturbances.
10
Q
diagnostic test for POI
A
FSH level
11
Q
Ectopic:
when can you do expectant:
hCG (1)
size (1)
A
<35mm
unruptured
asymptomatic
no fetal heartbead
hCG <1000
(involves closely monitoring the patient over 48 hours and if B-hCG levels rise again or symptoms manifest intervention is performed.)
12
Q
Ectopic:
when can you do medical management:
hCG (1)
size (1)
A
<35mm
no significant pain
no heart beat
hCG < 1,500
13
Q
medical management ectopic
A
methotrexate
pt has to be willing to attend follow up
14
Q
Ectopic:
when can you do surgical management:
hCG (1)
size (1)
A
> 35mm
hCG >5000
heart beat
pain
Salpingectomy is first-line for women with no other risk factors for infertility
Salpingotomy should be considered for women with risk factors for infertility such as contralateral tube damage (around 1/5 require further methotrexate/ salpingostomy)
15
Q
Infertility in PCOS - first line treatment
2nd line?
A
1st= clomifene
2nd line= metformin
(weight reduction)
16
Q
uterine fibroids short term treatment to reduce size
A
GnRH agonists
typically used more for short-term treatment due to side-effects such as menopausal symptoms (hot flushes, vaginal dryness) and loss of bone mineral density
17
Q
uterine fibroid surgical management
A
myomectomy: this may be performed abdominally, laparoscopically or hysteroscopically
hysteroscopic endometrial ablation
hysterectomy
uterine artery embolization
18
Q
Benign ovarian cyst management:
premenopausal
postmenopausal
A
PREMENOPAUSAL
a conservative approach may be taken for younger women (especially if < 35 years) as malignancy is less common. If the cyst is small (e.g. < 5 cm) and reported as ‘simple’ then it is highly likely to be benign. A repeat ultrasound should be arranged for 8-12 weeks and referral considered if it persists.
POSTMENOPAUSAL
by definition physiological cysts are unlikely
any postmenopausal woman with an ovarian cyst regardless of nature or size should be referred to gynaecology for assessment
19
Q
gestational sac containing a dead fetus before 20 weeks without the symptoms of expulsion
A
missed misscarriage
20
Q
threatened vs inevitable miscarroage
A
Inevitable miscarriage would have symptoms of imminent expulsion such as abdominal pain and vaginal bleeding with an open cervical os.
Threatened miscarriage would have vaginal bleeding with or without abdominal pain, with a closed cervical os.
21
Q
HIV and cervical cancer screening
A
Women with HIV should be offered cervical cytology at diagnosis.. Cervical cytology should then be offered annually for screening.
Even those women who are effectively treated with antiretrovirals have a high risk of abnormal cytology and an increased risk of false-negative cytology.
22
Q
bacterial vaginosis and Trichomonas vaginalis treatment
A
metronidazole
23
Q
thrust treatment options (2)
if pregnant (1)
A
oral fluconazole 150 mg as a single dose first-line
clotrimazole 500 mg intravaginal pessary as a single dose if oral therapy is contraindicated
if pregnant then only local treatments (e.g. cream or pessaries) may be used - oral treatments are contraindicated
24
Q
hormonal changes in menopause
A
The menopause can either be a natural or iatrogenic process that results in the cessation of oestradiol and progesterone production in the ovaries. Due to this decrease, FSH and LH levels will often increase.
25
temperature during period
Rises following ovulation in response to higher progesterone levels
Progesterone also highest in luteal (secretory) 15-28 days, as it is secreted by the egg
26
Urge incontinence management (2)
examples of the meds (3)
1. bladder retraining
2. anti muscarinic antagonist
NICE recommend oxybutynin (immediate release),
tolterodine (immediate release) or
darifenacin (once daily preparation)
27
who to not give oxybutynin to
Immediate release oxybutynin should, however, be avoided in 'frail older women'
28
duloxetine MOA
mechanism of action: increased synaptic concentration of noradrenaline and serotonin within the pudendal nerve → increased stimulation of urethral striated muscles within the sphincter → enhanced contraction
duloxetine may be offered to women if they decline surgical procedures
STRESS INCONTINENCE
29

maintenance: oral fluconazole weekly for 6 months
32
Most common benign ovarian tumour in women under the age of 25 years
Dermoid cyst (teratoma)
also called mature cystic teratomas. Usually lined with epithelial tissue and hence may contain skin appendages, hair and teeth
most common benign ovarian tumour in woman under the age of 30 years
median age of diagnosis is 30 years old
bilateral in 10-20%
usually asymptomatic. Torsion is more likely than with other ovarian tumours

commonly regress after several menstrual cycles
Follicular cysts
34
sample "inadequate" in cervical smear
repeat in 3 months
35
if 2x samples inadequate in cervical smear

36
HPV +ve by cytology normal (i.e NO borderline changes) --> repeat in 12 months.
if repeat:
normal? (1)
+ve? (1)
if the repeat test is now hrHPV -ve → return to normal recall
if the repeat test is still hrHPV +ve and cytology still normal → further repeat test 12 months later:
If hrHPV -ve at 24 months → return to normal recall
if hrHPV +ve at 24 months → colposcopy
(Cervical cancer screening: if 2nd repeat smear at 24 months is still hrHPV +ve → colposcopy)
37

day 21
38
fertility: what hormone to test for

41
VWD
Von Willebrand's disease is the most common inherited bleeding disorder. The majority of cases are inherited in an autosomal dominant fashion* and characteristically behaves like a platelet disorder i.e. epistaxis and menorrhagia are common whilst haemoarthroses and muscle haematomas are rare
Investigation
prolonged bleeding time
APTT may be prolonged
factor VIII levels may be moderately reduced

50
corpus luteum cyst
during the menstrual cycle if pregnancy doesn't occur the corpus luteum usually breaks down and disappears. If this doesn't occur the corpus luteum may fill with blood or fluid and form a corpus luteal cyst
more likely to present with intraperitoneal bleeding than follicular cysts
51
Benign epithelial tumours:
serous cystadeoma
mutinous cystaedoma
Serous cystadenoma (The most common type of epithelial cell tumour)
the most common benign epithelial tumour which bears a resemblance to the most common type of ovarian cancer (serous carcinoma)
bilateral in around 20%
Mucinous cystadenoma
second most common benign epithelial tumour
they are typically large and may become massive
if ruptures may cause pseudomyxoma peritonei
--> SEROUS CARCINOMA IS MOST COMMMON TYPE OF OVARIAN CANCER

100
Risk factors ectopic pregnancy
damage to tubes (pelvic inflammatory disease, surgery)
previous ectopic
endometriosis
IUCD
progesterone only pill
IVF (3% of pregnancies are ectopic)
101
stopping HRT
When stopping HRT it is important to tell women that gradually reducing HRT is effective at limiting recurrence only in the short term. In the long term, there is no difference in symptom control.
Although menopausal symptoms can be managed mainly in primary care, there are some instances when a woman should be referred to secondary care. She should be referred to secondary care if treatment has been ineffective, if there are ongoing side effects or if there is unexplained bleeding.
102
3rd stage labour bleed management
IV oxytocin
103
obstetric cholestasis management
induction of labour at 37-38 weeks is common practice but may not be evidence based
ursodeoxycholic acid - again widely used but evidence base not clear
vitamin K supplementation
104
medication of choice in suppressing lactation when breastfeeding cessation is indicated
Cabergoline
105
management PID
due to the difficulty in making an accurate diagnosis, and the potential complications of untreated PID, consensus guidelines recommend having a low threshold for treatment
first-line: stat IM ceftriaxone + followed by 14 days of oral doxycycline + oral metronidazole - this now considered first-line due to the desire to avoid systemic fluoroquinolones where possible
second-line: oral ofloxacin + oral metronidazole
RCOG guidelines suggest that in mild cases of PID intrauterine contraceptive devices may be left in. The more recent BASHH guidelines suggest that the evidence is limited but that ' Removal of the IUD should be considered and may be associated with better short term clinical outcomes'
106
complications PID
perihepatitis (Fitz-Hugh Curtis Syndrome)
occurs in around 10% of cases
it is characterised by right upper quadrant pain and may be confused with cholecystitis
infertility - the risk may be as high as 10-20% after a single episode
chronic pelvic pain
ectopic pregnancy
107
Mg sulphate in pre eclampsia
- should be given once a decision to deliver has been made
- in eclampsia an IV bolus of 4g over 5-10 minutes should be given followed by an infusion of 1g / hour
- urine output, reflexes, respiratory rate and oxygen saturations should be monitored during treatment
respiratory depression can occur: calcium gluconate is the first-line treatment for magnesium sulphate induced respiratory depression
- treatment should continue for 24 hours after last seizure or delivery (around 40% of seizures occur post-partum)
108
Premature ovarian insufficiency - how long to treat for
until 51 years
(with HRT/. combined therapy)
109
Wertheim's radical hysterectomy
includes removal of lymph nodes and is used to treat stage IIB endometrial carcinoma.
110
complications hyperemesis
acute kidney injury
Wernicke's encephalopathy
oesophagitis, Mallory-Weiss tear
venous thromboembolism
fetal outcome
studies generally show little evidence of adverse outcomes for birth weight/other markers for mild-moderate symptoms
severe NVP resulting in multiple admissions and failure to 'catch-up' weight gain may be linked to a small increase in preterm birth and low birth weight
111
Androgen insensitivity syndrome
X-linked recessive condition due to end-organ resistance to testosterone causing genotypically male children (46XY) to have a female phenotype. Complete androgen insensitivity syndrome is the new term for testicular feminisation syndrome
Features
'primary amenorrhoea'
little or no axillary and pubic hair
undescended testes causing groin swellings
breast development may occur as a result of the conversion of testosterone to oestradiol
112
Presence of a foetal heartbeat on ultrasound in the context of an ectopic pregnancy
indication for surgical management
113
when to manage miscarriage surgically/medically
increased risk of haemorrhage
she is in the late first trimester
if she has coagulopathies or is unable to have a blood transfusion
previous adverse and/or traumatic experience associated with pregnancy (for example, stillbirth, miscarriage or antepartum haemorrhage)
evidence of infection
114
medical management miscarriage:
missed miscarriage
incomplete miscarriage
missed miscarriage
oral mifepristone. Mifepristone is a progesterone receptor antagonist → weakening of attachment to the endometrial wall + cervical softening and dilation + induction of uterine contractions
48 hours later, misoprostol (vaginal, oral or sublingual) unless the gestational sac has already been passed. Misoprostol is a prostaglandin analogue, binds to myometrial cells → strong myometrial contractions → expulsion of products of conception
if bleeding has not started within 48 hours after misoprostol treatment, they should contact their healthcare professional
incomplete miscarriage
a single dose of misoprostol (vaginal, oral or sublingual)
a pregnancy test should be performed at 3 weeks
115
HELLP syndrome
severe form of pre-eclampsia whose features include: Haemolysis (H), elevated liver enzymes (EL), and low platelets (LP). A typical patient might present with malaise, nausea, vomiting, and headache. Hypertension with proteinuria is a common finding, as well as epigastric and/or upper abdominal pain.
116
To confirm ovulation what should you check
serum progesterone level 7 days prior to the expected next period
117
endometriosis treatment
The COCP is the first line option and can be used back-to-back with no pill-free interval. Second line treatments include progesterone only methods, such as POP, implant or injection (again they work by inhibiting ovulation). In addition, the Mirena coil can be used as it will reduce bleeding, resulting in less retrograde menstruation. The copper intrauterine device can make menstrual cycles longer and more painful and would not be a suitable option.
If the above methods fail to improve a patient's symptoms, then GnRH analogues may be used.
If analgesia/hormonal treatment does not improve symptoms, or if fertility is a priority, the patient should be referred to secondary care. Secondary treatments include:
GnRH analogues - said to induce a 'pseudomenopause' due to the low oestrogen levels
drug therapy unfortunately does not seem to have a significant impact on fertility rates
surgery
this may be an option for women who have not responded to conventional medical treatment
for women who are trying to conceive, NICE recommend laparoscopic excision or ablation of endometriosis plus adhesiolysis as this has been shown to improve the chances of conception. Ovarian cystectomy (for endometriomas) is also recommended
118
Premature ovarian failure definition
The onset of menopausal symptoms and elevated gonadotrophin levels before the age of 40 years'
119
how to manage placenta prevue
If low-lying placenta at the 20-week scan:
rescan at 32 weeks
no need to limit activity or intercourse unless they bleed
if still present at 32 weeks and grade I/II then scan every 2 weeks
final ultrasound at 36-37 weeks to determine the method of delivery
elective caesarean section for grades III/IV between 37-38 weeks
if grade I then a trial of vaginal delivery may be offered
if a woman with known placenta praevia goes into labour prior to the elective caesarean section an emergency caesarean section should be performed due to the risk of post-partum haemorrhage
major cause of death in women with placenta praevia is now PPH
120
when to do ECV ?
what contraindications?
36 weeks
where caesarean delivery is required
antepartum haemorrhage within the last 7 days
abnormal cardiotocography
major uterine anomaly
ruptured membranes

preterm labour - 15%, associated with polyhydramnios
Neonatal complications
macrosomia (although diabetes may also cause small for gestational age babies)
hypoglycaemia (secondary to beta cell hyperplasia)
respiratory distress syndrome: surfactant production is delayed
polycythaemia: therefore more neonatal jaundice
malformation rates increase 3-4 fold e.g. sacral agenesis, CNS and CVS malformations (hypertrophic cardiomyopathy)
stillbirth
hypomagnesaemia
hypocalcaemia
shoulder dystocia (may cause Erb's palsy)

oxytocin use
the presence of significant meconium
fresh vaginal bleeding that develops in labour - this was a new point added to the guidelines in 2014
124
when to start insulin in gestational diabetes
fasting glucose is >= 7 mmol/l. Aspirin should also be considered given the increased risk of pre-eclampsia.
