Mx of chickenpox exposure pregnancy
f there is any doubt about the mother previously having chickenpox maternal blood should be urgently checked for varicella antibodies
oral aciclovir (or valaciclovir) is now the first choice of PEP for pregnant women at any stage of pregnancy
antivirals should be given at day 7 to day 14 after exposure, not immediately
Mx of chickenpox in pregnancy
oral aciclovir should be given if the pregnant women is ≥ 20 weeks and she presents within 24 hours of onset of the rash
if the woman is < 20 weeks the aciclovir should be ‘considered with caution
Primary vs secondary amenorrhoea causes
Primary
gonadal dysgenesis (e.g. Turner’s syndrome) - the most common causes

Mirena if contraception
Ix and mx of endometriosis
laparoscopy is the gold-standard investigation
NSAIDs and/or paracetamol are the recommended first-line treatments for symptomatic relief
if analgesia doesn’t help then hormonal treatments such as the combined oral contraceptive pill or progestogens

MOA of desogestrel)
Inhibits ovulation
POP
MOA of Nexplanon
Releases the progestogen hormone etonogestrel.
They are typically inserted in the proximal non-dominant arm, just overlying the tricep.
The main mechanism of action is preventing ovulation. They also work by thickening the cervical mucus.

Primary: Inhibits ovulation
Also: thickens cervical mucus
MOA Of emergency contraception
Contraceptive Mode of action

women with blood pressure ≥ 160/110 mmHg are likely to be admitted and observed
Oral labetalol, Nifedipine (e.g. if asthmatic) and hydralazine may also be used
methods of contraception is proven to be associated with weight gain
Depot
Mx of ectopic pregnancy
Expectant
<35mm
Asymptomatic
NO heartbeat
hCG <1,000IU/L
Medical
<35mm
Unruptured
hCG <1,500IU/L
Not suitable if intrauterine pregnancy
Surgical
>35mm
Can be ruptured
hCG >5,000U
Pain
Expectant mx of ectopic preg
Expectant management involves closely monitoring the patient over 48 hours and if B-hCG levels rise again or symptoms manifest intervention is performed.
Rules of emergency contraception
Levonorgestrel
must be taken within 72 hours of unprotected sexual intercourse (UPSI)
the dose should be doubled for those with a BMI >26 or weight over 70kg
hormonal contraception can be started immediately after using levornogestrel (Levonelle) for emergency contraception
Ulipristal
30mg oral dose taken as soon as possible, no later than 120 hours after intercourse
Ulipristal may reduce the effectiveness of hormonal contraception. Contraception with the pill, patch or ring should be started, or restarted, 5 days after having ulipristal. Barrier methods should be used during this period
Cause of oligohydraminos
premature rupture of membranes
Potter sequence
bilateral renal agenesis + pulmonary hypoplasia
intrauterine growth restriction
post-term gestation
pre-eclampsia
Definition of oligohydraminos
less than 500 mL at 32-36 weeks’ gestation:
Gestational diabetes dx
fasting glucose is >= 5.6 mmol/L
2-hour glucose is >= 7.8 mmol/L
Gestational diabetes mx
if the fasting level is < 7 mmol/l a trial of diet and exercise should be offered
if not met within 1-2 weeks of altering diet/exercise metformin should be started
if glucose targets are still not met insulin should be added to diet/exercise/metformin
gestational diabetes is treated with short-acting, not long-acting, insulin
if at the time of diagnosis the fasting glucose level is >= 7 mmol/l insulin should be started
if between 6-6.9 mmol/l, and there is evidence of complications such as macrosomia or hydramnios, insulin should be offered
Menstruation cycle phases
Menstruation
Days1-4
Follicular phase (proliferative phase) Days 5-13
follicles develop in the follicular phase under the influence of FSH
Proliferation of endometrium
FSH results in the development of follicles which in turn secrete oestradiol
When the egg has matured, it secretes enough oestradiol to trigger the acute release of LH. This in turn leads to ovulation
Ovulation
Days 14
Luteal phase (secretory phase)
Days 15-28
Progesterone secreted by corpus luteum rises through the luteal phase.
High body temp
POP missed pill
‘Traditional’ POPs (Micronor, Noriday, Nogeston, Femulen)
If less than 3 hours late
no action required, continue as normal
Cerazette (desogestrel)
If less than 12 hours late
no action required, continue as norma
IF >3/13hrs
take the missed pill as soon as possible. If more than one pill has been missed just take one pill. Take the next pill at the usual time, which may mean taking two pills in one day
continue with rest of pack
extra precautions (e.g. condoms) should be used until pill taking has been re-established for 48 hours
CI to COCP
more than 35 years old and smoking more than 15 cigarettes/day

Endometriosis sx
Chronic pelvic pain
Dysmenorrhoea - pain often starts days before bleeding
Deep dyspareunia
Subfertility
Cervical excitation
Cervical excitation is found in both pelvic inflammatory disease and ectopic pregnancy.§
Types of miscarriage
Threatened
painless vaginal bleeding occurring before 24 weeks, but typically occurs at 6 - 9 weeks
cervical os is closed
Missed (delayed) miscarriage
a gestational sac which contains a dead fetus before 20 weeks without Pain is not usually a feature
cervical os is closed
Inevitable miscarriage
heavy bleeding with clots and pain
cervical os is open
Incomplete miscarriage
not all products of conception have been expelled
pain and vaginal bleeding

PCOS fertility aid
Infertility in PCOS - clomifene is typically used first-line
When able to stop contraception
after 1 year of amenorrhoea if aged over 50 years, 2 years if the woman is aged under 50 years
When to start labetalol
systolic > 140 mmHg or diastolic > 90 mmHg
Increases risk of down in combined test
11 - 13+6 weeks
↑ HCG, ↓ PAPP-A, thickened nuchal translucency
If a woman has a ‘higher chance’ results she will be offered a second screening test (NIPT) or a diagnostic test (e.g. amniocentesis or chorionic villus sampling (CVS).
What is quad test and when doe sit happen
if women book later in pregnancy the quadruple test should be offered between 15 - 20 weeks
quadruple test: alpha-fetoprotein, unconjugated oestriol, human chorionic gonadotrophin and inhibin A
Low AFP, oestradiol
High bHCG, inhibit
When able to start POP after birth
Immediately

Who cannot take ullipristal
caution should be exercised in patients with severe asthma
breastfeeding should be delayed for one week after taking ulipristal. There are no such restrictions on the use of levonorgestrel
