Q

A 2 yr old comes into the pediatrician with the the main complaint of He has not being able to keep anything down and often refluxes. His mom is worried that he is developmentally delayed. The mother says that the baby is often fussy in arches his back. You’ve come to find out that he has a furrow White exudate with more than 10 is eosinophils on egd. You believe that he has to have surgery in order to correct his issue. But before the surgery what do you need to do first? What does the furrow white exudate have to do with his issue?

A

The white exudate is from eosinophil esophagitis from the reflux of acid stomach contents back up. The reason he is developmentally delayed is because he’s not getting enough nutrients from GERD, FOOD AVERSION.

Sloppiness of lower esophageal sphincter, not well developed

You must do a 24 hour into a esophageal PH and impedance monitoring to qualify the severity of the reflux. This allows you to measure the directions of the boss movement via measurement of changes in resistance to alternating electrical current when the bolus passes by a pair of metallic rings mounted on the catheter.

Q

What is the difference between conjugated and unconjugated hyperbilirubinemia in a jaundice infant

A

Conjugated is from problems in the biliary tree

Unconjugated BiliRubin that is not bound to albumin, Is lipid soluble and can cross the blood brain barrier. It can be deposited in the basal ganglia and brain stem which can result in bilirubin induce neurologic dysfunction also known as kericterus

Q

What is the difference between a direct and indirect Coombs test?

A

Direct coombs is used in ABO incompatibility in newborns. Specifically in situations where hyperbilirubinemia is resulted from hemolysis. This test looks for antibodies directly on the RBC of the baby.

Indirect looks at the blood sample for antibodies that combine to certain RBCs, leading to problems if blood mixing should occur

Q

What are the pathologic causes of unconjugated hyperbilirubinemia in a newborn baby?

A

Conjugated bili is not normal. This is caused by increased Bilirubin production, deficiency of hepatic uptake, impaired conjugation of Bilirubin, and increase interhepatic circulation .

Breast milk jaundice. A factor in the breast milk that inhibits the conjugation of BiliRubin. Can last 3 to 6 weeks but it does not go away consider other things.

Q

How does phototherapy work to decrease BiliRubin levels in an infant?

A

It Isomerizes unconj bili making it water soluble. So it can be eliminated by the body without conjugation by the liver.
