MCC of anemia in the world
|
Iron deficiency
|
|
Pt presents with cheilitis, PICA, brittle nails, koilonychia, smooth tongue and formation of esophageal webs (Plummer-Vinson syndrome).
DX? |
Fe deficiency anemia
|
|
Most reliable lab value to DX Fe def anemia?
TX? |
Plasma ferritin is LOW
TX with PO ferrous sulfate |
|
This type of anemia is found in persons of Southeast Asia and Chinese origin?
This type of anemia is found in Mediterranean populations? |
alpha-Thalassemia
beta--Thalassemia |
|
What lab values tell you it is Thalassemia instead of Fe deficiency anemia?
How is DX confirmed? |
Ferritin levels are normal in Thalassemia, and low in Fe def
DX by hemoglobin electrophoresis |
|
Chronic alcoholism or lead poisoning are two causes of this acquired anemia?
What do you see on blood smear that confirms its lead poisoning? |
Sideroblastic anemia
Basophilic stippling of red cells |
|
Lab values seen in Anemia of chronic dz:
ferritin? serum Fe? TIBC? |
-Normal ferritin
-Decreased serum Fe -Decreased TIBC |
|
What is the hallmark of aplastic anemia?
|
Pancytopenia
and bone marrow is hypocellular |
|
Macrocytic anemia is due to ___ or ___
|
Folic acid deficiency
Vit B12 deficiency |
|
An alcoholic pt presents with sore tongue (glossitis), vague GI symptoms.
Blood smear shows macro-ovalocytes, hypersegmented PMN's, and Howell-Jolly bodies. DX? TX? |
Folic acid deficiency anemia
Oral folic acid |
|
MCC of Vit B12 deficiency
|
Pernicious anemia, which is lack of IF (intrinsic factor)
B12 must be bound to IF to be absorbed. Not enough IF leads to B12 def |
|
Pt presents with glossitis, vague GI symptoms, stocking-glove paresthesias, gait disturbances, decreased position and vibratory sense.
Blood smear shows macrocytic anemia with hypersegmented neutrophils. DX? TX? |
Vit B12 deficiency anemia
TX with B12 supplements |
|
Why is it important to always check both folate and B12 levels in megaloblastic anemia?
|
If you Tx a pt for folate def (when they really have B12 def), the anemia will correct itself but the neuropathy will progress and become permanent
|
|
Intrinsic causes for hemolytic anemia.
How are they acquired? |
G6PD deficiency (X-linked recessive)
Spherocytosis (Autosomal dominant) Sickle cell anemia (Autosomal recessive) |
|
Peripheral smears shows bite cells or Heinz bodies.
DX? |
G6PD deficiency
|
|
Pt presents with splenomegaly, generalized pruritis after bathing, HA, tinnitus, blurred vision.
DX? TX? |
Polycythemia vera
Phlebotomy |
|

DX? |
ALL

|
What is the hallmark of acute leukemia?
|
Pancytopenia with circulating blasts.
Blasts make up at least 20% of nucleated cells in bone marrow |
|
Pt (~60yo) presents with acute onset of bleeding (epistaxis, gingiva), bone/joint pain, purpura/petechiae.

Chronic Myelogenous Leukemia |
|

|
Pt presents with diffuse painless lymphadenopathy, wt loss, night sweats, CBC is normal.
DX? |
Non-Hodgkin's Lymphoma
|
|
>65yo presents with bone pain, renal failure, spinal cord compression, bone fractures.
"Punched out" (lytic) lesions are seen on skull xray; a monoclonal spike is seen on serum electrophoresis; 10% plasma cells in BM; and a (+) Bence Jones Protein in 24hr urine. DX? |
