Arrow Gyrus Daily Questions; Pediatrics #27

You are in charge of the nutrition support service in the hospital where you are practicing.The company that makes the vitamin/mineral mixture for total parenteral nutrition (TPN) has gone out of business and for the past 2 months you have been trying to fortify the parenteral nutrition mixtures through other sources. An 8-month-old infant with short gut, who has been on TPN for the past 4 months, presents with a curious erythematous desquamating rash around his mouth, buttocks, and a small amount on his hands and feet. Which nutrient deficiency is the most likely cause?

(A) vitamin A
(B) thiamin
(C) riboflavin
(D) copper
(E) zinc

Answer E.

(E) The rash described is called acrodermatitis which means dermatitis of the acral or outer points of the body. This is the classic rash associated with zinc deficiency.
