Obs and Gynae Flashcards
Hyperemesis Gravidarum is most pronounced in the ____ trimester (____ weeks). It can be distinguished from normal/physiological vomiting during pregnancy by 3 specific criteria:
____
____
____
1st trimester
0-13 weeks
>5% weight loss pre-pregancy
Clinical dehydration
Electrolyte Imbalance
Hyperemesis Gravidarum can lead to complications including:
Severe Dehydration
Anaemia
Malnutrition
Depression
Venous Thromboembolsim
Electrolyte imbalance (e.g hyponatraemia or wernicke’s encephalopathy)
Mallory-Weiss tear
Management of Hyperemesis Gravidarum includes:
1st line: Cyclizine / Promethazine / Prochlorperazine (dopamine antagonists)
2nd line: Metaclopramide (dopamine and 5HT antagonist)
3rd line: Odansetron (to be given with caution as can cause cleft palate if given in first trimester)- 5HT antagonist.
*can also giver ginger supplements and acupuncture to help vomiting*
If patients are severely dehydrated, have ketonuria (+3) and/or severe electrolyte imbalance – Admit to hospital.
Always consider psychological effects Hypermesis Gravidarum (i.e vomiting 10 times daily) could have on patient.
Misscarriage: Spontaneous death of foetus in utero before ____ gestation.
5 Types:
24 weeks - abdo pain and bleeding
OS open: I+I
Inevitable - Open cervical OS. Likely to dispel pregnancy without medical intervention. POC not seen.
Incomplete - Same as above but POC can be seen in vaginal canal
OS closed: TMC
Threatened - Abdo pain and vaginal bleeding but gestational sac and foetal heartbeat seen on TV ultrasound.
Missed - Patients didnt realise they were pregnant and present with Abdo pain and vaginal bleeding. The uterus still contains foetal tissue, but the foetus is no longer alive (i.e no foetal heartbeat on TV ultrasound). Cervical os closed.
Complete - Abdo pain and vaginal bleeding but the patient has passed foetal tissue. Cervical os is closed and no heartbeat or sac on TV ultrasound. No POC visible.
Septic - Abdo pain and vaginal bleeding but also gestational sac becomes infected. Patients likely to show systemic signs of sepsis.

Screening for down syndrome is done at weeks ___ and uses an algorithm that includes 4 main components. Name them.
10-14
Nuchal Translucency (> 6mm indicates possible down syndrome)
B-HCG (Very High in DS)
PAPP-A (low)
Maternal age

If patients miss their original Down Syndrome screening (i.e combined test 10-13 weeks), they can do another test (quad test) from ____ weeks which includes 3/4 components. Name them.
______ (up to 15 weeks only) and ______ (16+ weeks) are two tests that can be offered to confirm diagnosis if tests above indicate a high risk of DS.
14-20 Weeks
B-HCG -very high
Unconjugated Oestriol - low
Alpha FetoProtein (AFP) - low
+/- Inhibin A - low
NIPT - Non Invasive Prenatal Testing is now also an option and more accurate than the quad and combined test. But suspicion of trisomy 21 needs to be high to qualify for this test.
Chorionic Villous Sampling (up to 15 weeks only)
Amniocentesis (16+ weeks)
*both carry risk of misscarriage* (CVS higher risk)

Gestational Hypertension
Defined as blood pressure **_____** with no concomitant ____ after 20 weeks’ gestation in a woman with no PMH of hypertension.
Remember a blood pressure > _____ requires treatment, whilst a blood pressure >____ requires admission to hospital.
Management:
1st line:
2nd line:
>140/90 mmHg
Proteinuria
>150/100 mmHg
> 160/110 mmHg
Labetalol (b-blocker and thus contrindicated in asthma)
Nifedipine (ca channel blocker)
Gold standard investigation for Endometriosis:
Diagnostic Laporoscopy
3 types of emergency contraception:
Levonorgestrel (Progestogen) - must be taken no later than 72 hours post sexual intercourse.
EllaOne (Ulipristal acetate) - Preferred in patients with a high BMI. Must be within 5 days.
*both these oral forms work by inhibiting ovulation* - (if ovulation has already occured then they are not effective)
Gold standard is actually Copper IUD - spermicidal and causes endometritis. Must be within 5 days. *Only method that works after ovulation*. NB - not to be used if patient is pregnant Urine B-HCG.
Downsides - Permanent and invasive
______ hormone: Produced by granulosa cells of ovary. Good marker of ovarian reserve
Anti-Mullerian
Menopause < 40 yo can be investigated by checking which hormone?
FSH
*oestrogen low and so FSH not inhibited at pituitary*
Syphilis
STI caused by _______ bacteria
Primary syphilis – Painless ulcer (_____) and regional lymphadenopathy (inguinal)
Secondary syphillis - _____ involvement and _____ (attached)
Tertiary syphilis – Neurosyphilis, Cardiovascular , _____ syphilis (_____ lesions with centre of necrotic tissue)
*also important to note that syphillis has an older demographic to Chlamydia/Gonorrhoea, primarily affecting men between the ages of ____ , much like mycoplasma genitalium.
Treponema Pallidum
Chancre
Multisystem
Condylomata
Gummatous / Granulomatous
25-40
Classically, syphilitic aneurysms occur in 90% of cases on the thoracic aorta, and in 10% in the abdominal aorta

Post- menopausal bleeding is often benign (ex. _____ ) however a significant proportion of cases can be endometrial cancer and so further investigation with _____ is necessary
If TV ultrasound shows endometrial thickness > ____ then a ___ is needed to determine whether thickness is due to endometrial hyperplasia or endometrial cancer
Biopsy with no ____ indicates hyperplasia with a very low risk of associated cancer and so patient can be treated with ____ (ex. Oral or IUD ______ ) to reduce endometrial thickness. Patient should be reviewed in ____ with TV ultrasound and further biopsy.
Biopsy with ____ suggests high risk of progressing to endometrial cancer and 1st line management in post- menopausal women is a ____ . Endometrial ___ is also an option.
However, in younger reproductive females who would like to preserve fertility (ex. ____ patient more likely to get endometrial cancer), conservative management with ____ can be considered with patient reviewed (i.e TV ultrasound and biopsy every ____ )
Atrophic vaginitis
Transvaginal ultrasound
>4mm
biopsy
atypia
progestogens
levonorgestrel
6 months
Atypia

Ablation
PCOS
Progestogens
3 months
_____ , _____ and _____ can all increase the risk of endometrial cancer as they provide unopposed levels of oestrogen stimulation to the endometrium.
COOP
Obesity
Type 2 Diabetes Mellitus
Itching of the hands and soles of feet (particularly) at night with no rash is a common presentation of obstetric cholestasis (i.e blocking of the biliary tree). This leads to high levels of circulating ____ which causes itching to the skin.
If rash is present it suggests a ______.
Due to obstruction in the biliary tree, there is also a higher level of circulating bilirubin and this leads to____ , _____ and ____.
Low levels of bile salts in the intestine also reduces the ability of the intestine to absorb ____ soluble vitamins such as ____ , and thus may lead to a _____ - Dangerous in the event of a bleed.
Bile salts
Polymorphic eruption of pregnancy - no blisters / pemphigoid gestationis - blisters (autoimmune skin eruption - more common in people with graves etc.)

Fat soluble
Vitamin K
Coagulopathy (High INR/high PT)

- Obstetric cholestasis is associated with an increased risk of ____, ____, and _____.
Pre-mature birth, **stillbirth** and meconium passage.
In obstetric cholestasis remember that patients will have deranged ____ and increased levels of circulating bile salts on blood investigation.
**Remember** it is normal for ___ to rise in pregnancy as the ____ produces it. Thus an isolated rise in ___ is normal in pregnancy and not indicative of pathology

Placenta
ALP
Management in obstetric cholestasis includes:
_____ improves LFTs, bile salts and symptoms.

Condition resolves after _____.

An important differential in PID to consider is a ____ . This is a late complication of PID and is life threatening condition if ruptures as can cause sepsis. _____ used to rule this out.
