Maternal Med Flashcards
Neonatal outcome with poor glycaemic control
Congenital malformations
Stillbirth
Neonatal death
Risk of neonatal+ perinatal death is significantly higher in T2DM than T1DM
True
Differentials for skin conditions
• PUPPS
• Pemphigoid gestationis
• Atopic eruption in pregnancy
• Eczema/ Psoriasis
• OC -> excoriations but typically no rash
• DHx, allergic reaction, contact dermatitis
• Pre-existing auto immune (SLE/ TB/ Sarcoid etc)
• Viral -> CMV, EBV, Parvovirus, Measles, Rubella, HIV, Zika, VZV, Meningitis…
• Fungal
• Parasitic -> scabies
CF - worse outcomes if
FEV1 <60% predicted
B. Cepacia infection (can lead to rapid deterioration of lung function)
Pulmonary hypertension
Cor pulmonale
Cyanosis
Hypoxia
Malnutrition (BMI <22)
Other related conditions (DM, cirrhosis, CKD)
3 skin conditions of pregnancy
Polymorphic eruption of pregnancy (PEP). Pemphigoid gestationis. Atopic eruption of pregnancy.
Frequency 1:200, RARE 1:10000, 1:300
Mitral stenosis risk
(Moderate - Severe)
Maternal
Death 1-3%
Pulmonary oedema 18-37%
New or recurrent arrhythmia 5-16%
Fetal
Stillbirth 2-4%
Neonatal death 0-2%
PTB 10-18%
APS blood tests (2 tests > 12/52 apart)
Anticardiolipin antibodies
Lupus anticoagulant
Anti beta-2-glycoprotein-1 antibodies
SLE bloods
Anti nuclear antibodies (ANA)
aPLs (anticardiolipin antibodies and lupus anticoagulant) (40%) - predicts severity
Anti Ro and Anti La (30%)
C3 and C4
Anti dsDNA antibodies

Liver function
Proteinuria
Serious associated maternal risks with HG
Wernicke’s (vit B1, thiamine Def)
Hyponatremia
Peripheral neuropathy (but B12, B6 Def)
VTE

CF 1:35 (1:25 European)
Spinal muscular atrophy (SMA) 1:50
Fragile X (1:332)
Thalassemia 1:10000 (3% Indians carry beta)
Overall 1:20 carry CF, SMA or Fragile X
1:10 Afrocarribean’s carry SCD.

Maternal infection
3 virus and 1 parasite that you do amnio for
CMV, varicella, Rubella
Toxo
Myasthenia Gravis - fetal effects
Arthrogryposis (contractures due to lack of movement)
Impaired swallowing - can cause Poly

IUGR
Transient neonatal MG (10-20%)
Kell summary
Pt must be Kell neg
To be affected fetus must be Kell pos
Inhibits erythropoiesis (not haemolysis)
2/52 MCA PSV from 18/40 + for developing hydrops
RA history
Extra-articular features - anaemia, fatigue, vasculitis, subcut nodules, pulmonary, cardiac amyloid, pericarditis
Neck involvement - atlanto-axial subluxation
Previous VTE
?Sjogrens
Echogenic bowel f/u
Even if no cause found, still need 4/52 scans as increased risk of SGA and IUFD
