Q

eosinophils is found in which lymphoma…. NHL or HD?

A

HD— think of mixed cellurality

32
Q

smudge cell might be indicative of which leukemia

A

CLL

33
Q

CLL has a unmutated and a mutated forms tell me about it

A
  1. unmutated means that the mutation happened before the B cell encounterd an antigen and this is a worse prognosis
  2. mutated means that the mutation happened after the B cell encuntered an antigen and this is a better prognosis
34
Q

two highest risk factors for CLL

A
  1. rai stage III/IV

2. 17p deletion

35
Q

ibrutinib

A

BTK inhibitor for CLL

36
Q

idelafisib

A

PI3K lambda inhibitor for CLL

37
Q

venetoclax

A

BCL2 inhibitor for CLL

38
Q

mantle cell lymphoma has what type of markers

A

CD5+ and CD23-

39
Q

as we learn more abut CLL we found that CLL cells are getting signals from the lymph node microenvironment to stay alive thus this has lead to changes in treatment

A

we need to take account of the lymph node Microenv. and thus tackling BTK is a good idea

40
Q

rouleaux formation on peripheral smear why? and what disease

A

in crease in M protein leading to mor sticky. this is found in multiple myeloma

41
Q

in multiple myeloma a decrease in B2-microglobulin and a increase in serum albumin is a bad or good prognosis

A

good pronosis

42
Q

in multiple myeloma an increase in B2-microglobulin and a decrease in serum albumin is a bad or good prognosis

A

bad prognosis

43
Q

Characterized by the dysregulated production of a particular lineage of mature myeloid or erythroid cells with fairly normal differentiation

A

MPN’s

44
Q

Characterized by the dysregulated production of a particular lineage of mature myeloid or erythroid cells with abnormal differentiation

A

myelodysplastic syndrome

45
Q

MDS that has a favorable course and response to lenalidomide

A

A

skin gut and liver

47

  4. sequestration crisis
A
  1. vaso-occlusive- acute pain exarcebations
  2. hemolytic crisis- marked increase red cell hemolysis
  3. aplastic crisis- erythroid aplasia due to parvo B19
  4. sequestration crisis- splenic pooling of erythrocytes with splenomegaly and shock-like state
