Microcytic hypochromic anemia with basophilic stippling. Ringed sideroblasts in bone marrow.
Lead poisoning
Serum Lead > 10
Tx is removal of source of lead
Can use succimer (oral chelation) for inpatient management.

Distal ileum
What test do you order to differentiate B12 vs Folate?
MMA
Alcoholic patient or a patient with an unbalanced diet.
Fatigue, exercise intolerance, pallor, glossitis, apthous ulcer, diarrhea, malabsorption.
Absent neurologic symptoms.
Normal MMA.
Folate deficiency
Increased ferritin + decreased TIBC + decreased serum iron
Anemia of chronic disease
What should you think a patient has if they have a microcytic anemia with a normal or increased serum iron or no response to iron tx.
Thalassemia
Microspherocytes and Coombs POSITIVE
Autoimmune hemolytic anemia
Microspherocytes and coombs NEGATIVE
Hereditary spherocytosis
Tx for a patient with recurrent episodes of hemolysis: anemia, jaundice, and splenomegaly.
Peripheral smear shows hyperchromic microcytosis, spherocytes
Increased MCHC
Coombs test negative.
Hereditary spherocytosis
Folic acid
Splenectomy if severe
Patient with dactylitis.
Can present with splenomegaly and rapid decrease in hemoglobin.
Peripheral smear shows sickled erythrocytes and or Howell-Jolly bodies.
Sickle cell disease

Tx for sickle cell
IV hydration and oxygen for pain control
Tx for a patient with mucocutaneous bleeding, anemia, jaundice and splenomegaly.
Patient may have neurologic symptoms such as headache, visual changes, confusion.
Labs show thrombocytopenia (low platelets) with normal PT and PTT.
TTP

Common in kids after recent hx of gastroenteritis
Associated with Enterohemorrhagic E. coli
Abd pain, bloody diarrhea, oliguria and hematuria
