Q 
Connect the following causes of neonatal resp distress & underlying pathology/ 'classic' feature:
A - Transient tachypnoea of newborn
B - Resp distress syndrome
C - Persistent pHTN
D - Sepsis
E - Pneumothorax

2 - surfactant deficiency; resp distress appears later & progressively worsens
3 - maternal fever, GBS+, baby has non-specific signs (poor tone, malodour, apnoea, poor feeding, nausea, poor perfusion)
4 - baby required resuscitation and has unequal air entry; higher risk of pulm hypoplasia, pneumonia and meconium aspiration

Q

Vit K deficient bleeding in a neonate typically presents with bleeding at which sites? There is a higher risk of occurrence with (breast/ formula) feeding.

A

GI bleeding; mucosal membranes; umbilicus; circumcision wounds
(intracranial bleeding is rarer, but accounts for ~50% of late presentations and has a mortality rate of 20-50%)

Q

What is the underlying pathogenesis of hypoglycaemia in a preterm neonate?
Provide 3 other risk factors for hypoglycaemia in a neonate (regardless of gestation)

A

Preterm hypoglycaemia d/t a) limited glycogen & fat stores; b) impaired gluconeogenesis; c) increased glucose utilization for relatively larger brain size; d) unable to mount counter-regulatory response

Other causes of neonatal hypoglycaemia:
Maternal: diabetes, intrapartum glucose, meds (oral hypoglycaemics, citalopram, ß-blockers, valproate)
Neonatal: IUGR/SGA or macrosomia, resp distress, sepsis, congen cardiac defect, metabolic disorder, hyperinsulinism, hypopituitarism, hypoxic insult, hypothermia, inadequate feeding, Rh haemolytic disease

Q

True or false: the risk of a serious bacterial infection is greatest in the neonatal period?
Why/ why not?

A

True
Young infants
- Are more likely to present with non-specific signs & can’t localise infection due to immature hypothalamic and immune systems
- Are too young to have received vaccines for potential pathogens
- Have declining levels of maternal antibodies & are only beginning to produce their own
- Can deteriorate rapidly

Both: male
Perthes: Caucasian, short stature/ growth delay, FHx (10%)
SUFE: overweight, African-American/ Pacific Islander, renal osteodystrophy, hypoTH or hypopituitarism, gonadal conditions
4) Treatment
Perthes: conservative (rest, avoid weight bearing), bracing/ petrie casting or surgical (‘shelf procedure’, hip replacement)
