A2 - Sunshine, Philip PY - 2015 T2 - Neonatology: Clinical Practice and Procedures AB - The most common concern for neonates who present with poor feeding, tachypnea, hypothermia, and lethargy during the first days of life is sepsis; in fact, this is the most likely cause of severe illness. However, it is important to also consider the possibility of an inborn error of metabolism. Although individually these are rare disorders, as a group they probably are present in more than 1 in 5000 live births1; if they are not identified early, most die or are left with severe brain damage.
