  3. Iron Deficiency Anemia

  4. Family lives on a farm and brings in their 2yo for you to examine… Child is pale and an HPD reveals a hemoglobin 4g/dl, MCV 102fl You diagnose a macrocytic anemia secondary to what?

  5. Folate deficiency Unpasteurized Goat’s Milk

  6. 7 yo boy with: fever x 1 week Hemoglobin 9g/dl WBC 1,200 Plt 32K Ferritin 6000

  7. What’s his diagnosis? Hemophagocytic syndrome

  8. Non-malignant disorder of antigen-presenting macrophages Caused by: Uncontrolled hemophagocytosis Defective NK cell function Cytokine upregulation Familial and sporadic forms Appears in association with: Bacterial, parasitic or viral (EBV) infections Malignancy Drugs Connective tissue disorders (SLE, Kawasaki’s) Diagnosis: Fever, splenomegaly Cytopenias (>2 cell lines) Elevated ferritin, triglyceride Hemophagocytosis in marrow, spleen, lymph nodes Prompt diagnosis/treatment essential Hemophagocytic Syndrome

  9. 14 month old African-American child presents with mild anemia – HPD obtained and when reviewed showed these cells. What are they? What is this?

  23. Frantic doctor refers a child to your practice with a platelet count of 20K. Child has no bleeding problems and is completely healthy. What’s your diagnosis?

  24. Pseudothrombocytopenia EDTA

  25. Another child presents with epistaxis, “wet” purpura in mouth and bruises/petechiae over trunk and extremities Platelet count 2K with remainder of counts normal
