90
Q

GDM Mx

A

If fasting glucose >7, give insulin
6-6.9 - lifestyle and metformin
6-6.9 + macrosomia - insulin

91
Q

Explain a molar pregnancy

A

A molar pregnancy is where a foetus doesn’t form properly in the womb and a baby doesn’t develop.
A lump of abnormal cells grows in the womb instead of a healthy foetus.
This growth is called a “hydatidiform mole”, which can be either:
a complete mole, where there’s a mass of abnormal cells in the womb and no foetus develops
a partial mole,where an abnormal foetus starts to form, but it can’t survive or develop into a baby

92
Q

Complete vs partial mole

A

Complete mole: haploid sperm duplicates to become diploid, which fertilise an empty ovum, this proliferates to form abnormal placental tissue

Partial mole: triploid due to diploid sperm plus maternal DNA

93
Q

What is a choriocarcinoma?

A

Malignant trophoblastic cancer of the placenta

Rapidly growing and often metastasises to the lungs

94
Q

Symptoms of molar pregnancy

A

Bleeding in first trimester, hyperemesis, uterus large for dates

95
Q

Management of molar pregnancy

A

Evacuation by suction curettage for smaller moles, may need oxytocic agent for larger moles. Give anti-D

Measure HCG every 2 weeks after evacuation at SPECIALIST CENTRE (CX). Rate of decrease in HCG indicates risk

Chemotherapy offered to destroy persistent trophoblastic tissue to minimise choriocarcinoma risk

DO NOT get pregnant until 6 months after HCG normal

98
Q

How common is it to carry GBS? Why do we worry about it?

A

25% of women

Worry because can cause sepsis and death, high risk of deafness and cerebral palsy in survivors

99
Q

HIV in pregnancy, opening line

A

HIV is a virus that damages the cells in your immune system and weakens your ability to fight everyday infections and disease

There is a risk that a mother can pass HIV to her baby, but with treatment and precautions this reduces from 25% to <1%

100
Q

Additional tests required in HIV in pregnancy

A
Hepatitis C 
Varicella zoster
Measles
Toxoplasma 
HIV: viral load, CD4 count, HIV resistance testing, LFTs, monitor for drug toxicity
Screen genital infections
101
Q

Tx for HIV in pregnancy

Treatment with zidovudine mono therapy may be considered if viral load <10000 and willing to have CS

102
Q

Tx for babies born to HIV infected mothers

A

ARVs within 4 hours until 4-6 weeks old

Tested for HIV within first 2 days, confirmed at 18 months

103
Q

What do you do if the HIV patient refuses treatment and what are the rights of the fetus in this case?

A

Pre-birth planning meeting with social services to discuss safeguarding issues
Tell the mother that it is the paediatrician’s role to advocate on behalf of the child’s wellbeing and to prevent where possible HIV infection
If she continues to refuse, legal permission should be sought at birth to treat the infant for 4 weeks with ART and prevent breastfeeding

104

Preterm delivery
GDM (test for this if already on HAART)
Pre-eclampsia

108
Q

Key points for drug use in pregnancy

A

This patient should be managed as a high-risk patient and with a MDT approach

She should be discussed with the Drug & Alcohol services team and should receive specialised antenatal care from them.

She should be advised not to immediately cut out all drugs, as withdrawal would be dangerous.

Detoxification with methadone could be started.
