Q

Define transient hypoglycaemia of the newborn
Other causes for reduced glucose in newborns?
- maternal factors
- fetal factors
Management for prolonged/severe hypoglycaemia of the newborn
: if symptomatic, or glucose <1mmol (jittery, poor feeding, seizures, drowsiness..)
- if asymptomatic, low glucose but >1mmol

A

Blood glucose <2.6mmol without symptoms. Common and normal within first 24hrs of life.
Blood sugars drop due to the stress of birth; and after transition from maternal blood to their own blood.
Lowered glucose causes -
* maternal diabetes, beta blocker use
* fetal - large birth weight, BW syndrome
* increased demand - sepsis, HIE, hypothermia, prem.

Mx-
* 10% dextrose IV, NICU.
* Or encourage normal feeding (breast/bottle) and monitor blood glucose frequently (e.g every 2hours)

Q

Distinguish oomphalocele from gastroschisis.
How does the mx differ?
Which is associated with Beckwith-Wiedemann syndrome and Down’s?

Q

Antenatal screening for trisomy 21, 18 and 13. (Down’s, Edward’s, Patau’s.)
* 1st line, 11-14 weeks = Combined test (21, 18, 13).
* 14-20, e.g. if women have missed original combined test: Quadruple test (21) & 20-week scan (18, 13).

What do these tests include?

What would the bloods from a neural tube defect show?

A
  • Combined -Ultrasound (nuchal translucency; thickness >6mm) & maternal bloods (beta hCG, PAPPA). High risk for Down’s = high beta-HCG, low PAPP-A. For Trisomy 13 and 18 = similar results to Down’s but hCG tends to be lower.

ARPK disease is a congenital condition caused by mutation on chromosome 6. This affects epithelial tissue production of which organs?

A

Ix: Abdo U/S, MCUG (micturating cysto-urethrogram), cystoscopy
PUV
* can be detected antenatally as bilateral hydronephrosis / olighydramnios
* palpable bladder O/E
* monitor +/- removal of excess tissue during cystoscopy

VUR

* req abx prophylaxis (surg if severe)

ARPK
- much less common than autosomal dominant form, can be detected antenatally with abdominal mass

  • preceded by gastroenteritis (E-Coli producing Shiga toxin or Shigella producing); 5 days of blood diarrhoea
  • antihypertensives (renal protective) +/- transfusion or haemodialysis
  • because abx/antimotility (Loperamide) can increase the risk of Shiga toxin and thus increase risk of HUS
