b. CD 10
c. CD 13
d. CD 19
Most common type of congenital leukemia
is
a. ALL
b. AML
c. CLL
d. CML
Which of the following statements pertaining to leukemia is correct?
A. Blasts of acute myeloid leukemia are typically sudan black negative
B. Blasts of acute lymphoblastic leukemia are typically myloperoxidase positive
C. Low leucocyte alkaline phosphatase score is characteristically seen in blastic phase of chronic myeloid leukemia
D. Tartarate resistant acid phosphatase positivity is typically seen in hairy cell leukemia
Correct answer : D. Tartarate resistant acid phosphatase positivity is typically seen in hairy cell leukemia
 In sickle cell disease:
a. the disorder is a single gene disorder T
b. carrier has normal blood test F
c. the abnormalities involves the alpha chain of the globin
    molecule F
d. there is absence of HbA T
e. sickle cell crisis does not affect carrier of the disease F
– In sickle cell, HbA is replaced by HbS
– HbS has a valene in place of glutamic acid in the sixth amino acid residue of
beta globulin molecule

b) HD more often tends to remain localized to a single group of lymph nodes and spreads by contiguity
c) Several types of non Hodgkin’s lymphoma (NHL) may have a leukemic phase
d) In general follicular (nodular)NHL has worse prognostic compared to diffuse NHL
Hodgkin’s Lymphoma most serious subtype is nodular sclerosis. What type of
cell is needed to diagnose HL?

– CD22
– TdT
– Cd10
– CD19
ALL of the above, except the question…I know, ridiculous!
 
 
Typical symptoms of ALL/lymphomas (and AML) include all of the following except
– sudden onset
– anemia
– bleeding
– vomiting
– nerve palsies
headache
 
What is seen mostly in mostly in children, where there are chromosomal changes,
, hyperploidy, Philadelphia chromosome*, translocations (9;22)
SIGNIFICANT response to chemo: 90% remission,
75% CURE!!!
Acute lymphoblastic leukemia
– Chronic LL
Examples of mutations in neoplastic proliferations of WBC for acute
leukemia are all except
– Transcription factor
– Tyrosine kinase
– peroxidase
 
 
All acute leukemias suppress normal hematopoesis, e.g., have
anemia and
– Blastomas
– Thrombocytopenia
– decrreased perforin
In the case of ___________,
there is an intimate concurrence with malignant lymphomas
lymphocytes
– erththrocytes
In the case of __________, the primary
process is marrow and peripheral blood, but can involve any
organ or tissue which receives blood.
– Lymphocytes
– neutrophilic precursors
 
Kostmann syndrome is genetic, congenital, eg, severe neutropenia.
What does this affect?
– Thio-uracil
Myelopoiesis
 
What number is the danger zone for
inadequate production / increased desctruction?
500-1000/mm3
– 50-200/mm3
In HIV infection (and autoimmune), you would be likely to see
– leukopenia, after glucocorticoids or cytotoxic drug treatment
– high CD4 count
Another bane for B12 is _______. In what anemia would you see
this deficiency?
Cobalamin, pernicious anemia
– Thiamine, Barrett’s esophagus
Lack of what causes anemia in B12 deficiency?
– Cobalamin
Folate
 

B12 combines with intrinsic factor in the gastric mucosa and is absorbed
– in the cecum
in the terminal illeum
– in the duodenum

How about folate?
proximal jejunum (yup, it’s the one at the top!)
– cecum

As for enlarged RBC, megaloblasts are in the bone marrow,
what are in the peripheral blood?
macro-ovalocytes
– micro-ovalocytes

As for giant WBC, what are seen in the marrow, peripheral blood?
– Blastocysts, lymphophils
giant metamyelocytes, hypersegmented neutrophils

Megaloblastic anemias (non-hemolytic, MCV > 94, macrocytes in peripheral smear)
are due to impaired DNA synthesis and are
also called
anemias of B12 and Folate deficiency
none of the above

In HGB-S disease (sickle cell), you may see
autosplenectomy, but what infections would you become
more susceptible to?
– Clostridium
– pneumococcus, Hem. influ, salmonella, osteomyelitis


Classic hemoglobinopathy
Normal HGB is α2β2: β-chain defects (Val->Glu)
Reduced hemoglobin “sickles” in homozygous
8% of American blacks are heterozygous
scickle cell anemia
– A.L.L.

The sickle cell trait –

Sickle cell trait (or sicklemia)
describes a condition in which a person has one abnormal allele of the hemoglobin
beta gene (is heterozygous), but does not display the severe symptoms of
sickle cell disease that occur in a person who has two copies of that
allele (is homozygous).

Those who are heterozygous for the sickle cell allele produce both normal and abnormal hemoglobin (the two alleles are codominant with respect to the actual
concentration of hemoglobin in the circulating cells).
