In neonates, jaundice becomes clinically apparent when serum bilirubin levels rise past what point?
> 5mg/dL
Which type of hyperbilirubinemia, conjugated (direct) or unconjugated (indirect), is always pathologic and never physiologic?
Conjugated (direct)
What type of jaundice is due to indirect hyperbilirubinemia which occurs in the absence of any underlying abnormalities in bilirubin metabolism?

Between days 3-5 at or below 12-15mg/dL
Most common cause of nonphysiologic unconjugated hyperbilirubinemia?
ABO incompatibility
Common causes of nonphysiologic conjugated hyperbilirubinemia?
Diseases involving the liver (biliary atresia, neonatal hepatitis) and congenital infections
Test that detects maternal antibody on the surface of neonatal RBCs and is positive in ABO incompatibility
Direct Coombs test
Test used to identify the specific type of maternal antibody present on neonatal RBCs in ABO incompatibility
Indirect Coombs test
On physical exam, how does jaundice progress in a neonate’s body?
Progresses in a cephalopedal direction and disappears in the opposite direction
In neonates with unconjugated hyperbilirubinemia, what treatments are available after hydration status is normal?

Unconjugated only
What respiratory rate is necessary for a diagnosis of tachypnea in a neonate?
> 60 breaths/min
Tx for pertussis
Erythromycin or Azithromycin can shorten duration of illness if given early in the catarrhal phase - not after the coughing begins
1 month-old WF presents with tachypnea (60 breaths/minute), irritability, poor feeding, and low-grade fever. What do you suspect?
Pneumonia (tachypnea out of proportion to fever)
You suspect a patient has meningitis. As part of your PE, you have the patient lie on his back while you extend his leg at the hip. You then extend his lower leg at the knee and he gasps in pain. What is this sign?
Kernig sign
You suspect a patient has meningitis. As part of your PE, you have the patient lie on his back with his arms and legs straight. You then flex his neck and he reflexively flexes his legs at the knee. What is this sign?
