I am aware of the diagnosis in this
case. This newborn boy, born prematurely at a
gestational age of 29 weeks, had a relatively typical
course in the NICU until suddenly, on his sixth
day of life, progressive multiorgan system failure
developed, and he died early on his seventh day of
life. For diagnostic possibilities, I considered four
categories of neonatal disorders: inborn errors of
metabolism, respiratory failure, cardiomyopathy,
and bacterial or viral sepsis.
