Pediatric Hematology Flashcards
Neonates with this disorder present with isolated thrombocytopenia and absent radii with thumbs.
Thrombocytopenia Absent Radii (TAR)
True/False. Formula is a protective factor against iron-deficiency anemia as it is fortified with iron.
False - formula does not have iron. Babies who are exclusively breastfed are less likely to become iron deficient
What risk factor is most associated with folate deficiency in babies?
Exclusive goat’s milk consumption
Lead toxicity will cause what type of anemia?
Microcytic, hypochromic
What is the most common risk factor for the development of iron-deficiency anemia in infants?
Cow milk intake - especially before 1yo
True/False. Nucleated RBCs should not be seen in newborns.
False - nucleated RBCs are present until a week after birth
A newborn’s Hb levels will be (higher/lower) than adult levels at birth.
Higher - the fetus is in a relatively hypoxic state so increased Hb is needed
How are hemorrhagic disorders prevented in newborns?
Vitamin K injection at birth
What is the most common cause of anemia in children?
Iron Deficiency Anemia
What is the leading cause of death in adolescents with sickle cell disease?
Acute Chest Syndrome
True/False. Most pediatric cases of lead toxicity in the US are not severe and do not require intervention.
True - treatment is required when lead levels exceed 45mcg
This disorder is characterized by pancytopenia, absent thumbs, and an increased risk of leukemia.
Fanconi anemia
What is idiopathic thrombocytopenic purpura?
Destruction of platelets bound by antibodies. This often occurs after an acute viral infection
What is the most common cause of B12 deficiency in babies?
Exclusive breastfeeding by vegan mothers
What is physiologic nadir of infancy?
Occurs around 2 months, this is a low point in Hb (9-11) following birth before increasing
This is a disorder characterized by deficient RBC precursors and abnormal thumbs.
Diamond-Blackfan Syndrome
