Q

a 52-year-old male who reports that he has been feeling very tired lately, and his wife thinks that he looks pale. You order a complete blood count, which shows: Hgb 8.5 g/dL (normal 13.5-17.5); WBC 1,200/microliter (normal 4,500 – 11,000); platelets 70,000/microliter (normal 150,000 – 400,000). The patient is referred for bone marrow biopsy, which shows myeloblasts with Auer rods.
what is the diagnosis

AML (acute myeloid leukemia)

Q

a 49-year-old healthy male without complaints, but on a routine complete blood count (CBC) has markedly increased white blood cell count of 40,000 per uL (normal 4500 – 11,000). A peripheral blood smear demonstrates leukocytosis with myeloid cells present at various stages of differentiation, with more mature cells present at a greater percentage than less mature cells. The cytogenetic analysis is positive for the Philadelphia chromosome.

Q

what factor is diminished with Hemophilia B

22
Q

a 30-year-old woman with a recurrent history of nosebleeds and heavy menses. She recently read that taking a baby aspirin was good for the heart. However, ever since she started taking aspirin, she has been experiencing more and more nosebleeds. Her father and paternal uncle similarly have histories of prolonged nosebleeds. Labs show increased PTT, normal PT, and increased bleeding time.
what is the diagnosis

23
Q

what is the treatment of VWD

A

DDAVP (desmopressin)
or tranfusion if massive bleeding

24
Q

what is virchows triad

A

blood stasis
hypercoagulable state
vascular injury

25
what is factor V leiden
procoagulant clotting favor - amplifies production of thrombin a clot formation
26
how is factor V leiden diagnosed
activated protein C resistance assay normal PT/PTT
27
what is the treatment of factor V leiden
LMWH bridge to warfain; long term antithrombotic therapy is not recommended
28
what is protein C deficiency
vitamin K dependent anticoagulant liver protein that stimulates fibrinolysis and clot lysis (inactivates factor V and VIII) – potentiated by protein S
29
what is the treatment of protein C deficiency
heparin and oral anticoagulation for life
30
what is protein S deficiency
vitamin K dependent that is a cofactor for activated protein C, which inactivates procoagulant factors Va and VIIIa ⇒ reducing thrombin generation
31
what is antithrombn III deficiency present with
recurrent venous thrombosis and PE, repetitive intrauterine fetal death (IUFD)
32
what is antithrombin III
natural anticoagulant; inhibits thrombin (IIa), Xa and other proteases; potentiated by Heparin
33
what is antiphospholid antibody syndrome
autoimmune; often associated with SLE; characterized by thromboses and recurrent spontaneous abortions
34
how is antiphospholipid antibody syndrome diagnosed
lupus anticoagulant anticardiolipin DRVVT test prolonged PTT
35
what is the treatment of Antiphospholipid antibody syndrome
High dose IV heparin with thrombotic events then oral anticoagulation indefinities
36
what is the presentation of Hodgkins lymphoma
painless lymphadenopathy + bimodal age distribution (15-35) and (>60) Fever, chills, and night sweats for > 1 month Painless enlarged posterior cervical and supraclavicular lymph nodes Virchow’s node
37
what is the diagnostic test for Hodgkin lymphoma
CXR - mediastinal adenopathy excisional bx of lymph nodes with Reed-Sternberg cells
38
what is the presentation of Non-Hodgkin lymphoma
immunocompromised (HIV) patient with GI symptoms and painless peripheral lymphadenopathy
39
what is polycythemia vera
malignancy of the bone marrow that results in overproduction of RBC and can also affect platelets and WBCs
40
what are classic symptoms of polycythemia vera
pruritis s/p hot baths swelling, burning pain and rubor of hands and feet
41
what is erythromelalgia
swelling, burning pain, and rubor of the hands and feet
42
what are the 4 H's of polycythemia
Hypervolemia, Histaminemia, Hyperviscostity and Hyperuricemia
43
what is the treatment of polycythemia

what is idiopathyic thrombocytopenic purpura (ITP)
Autoimmune reaction to platelets usually after a viral illness
45
what is the treatment of ITP
children - supportive care (IVIG for refractory cases) adults - prednisone
