Lectuer1 Part 2 Flashcards
What do we mean by Benign?
It’s no malgnincy disorders
we have two methods to notice any change in leukocytes what are they ?
Quantitative and Qualitative
Quantitative mean? and what Terminology we use it ?
Change in number
Cytosis / philia
Increase in number
Cytopenia/penia
Decrease in number
Qualitative
mean?
changes in Morphologic or Functional
if the total WBC is 25,000, the absolute
value (40% of 25,000) calculate the absolute value?
Calculation: absolute count= Total WBC x percent
25,000*40=100,000/100=10,000
ياحلوات هنا مره مهم تعرفون الformula تضربون القيم وبالنهاية تقسمون الناتج على 100
differentiation in WBC to 3 specific cells? please mentioned the names with examples?
1-Leucocytes
Phagocytes
Granulocytes
Neutrophils
Basophils
Eosinophils
2-Lymphocytes
B-cells T-cells
3-Mononuclear phagocytic cells
Monocytes
Macrophage and denderetic
cells
What the difference between LEUCOCYTOSIS and LEUCOPENIA?
LEUCOCYTOSIS //
Raised TWBC above 11.0 x 109/L in adults, due to elevation of any of a single lineage.
Note: elevation of the minor cell
populations can occur without a rise in the total white cell count.
LEUCOPENIA//
TWBC lower than 4.5 x 109/L in elevation of any of a single lineage.
Leucopenia may affect one or more lineages and it is possible to be severely neutropenic or lymphopenic without a reduction in total white cell count.
What the difference between Granulocytosis and Agranulocytosis?
*Granulocytosis Increase in the count of all or one of the granulocytic component: Ex: Neutrophils Basophils Eosinophils
*Agranulocytosis
Decrease in the count of all or one granulocytic component
Definition of NEUTROPHILIA ?
Increase in the number of neutrophils and / or its precursors
True or false
In adults count<7.5 x 109/L but the counts are shape
dependent
False /
adults count >7.5 x 109/L but the counts are age
dependent

Mention the Causes of Neutrophilia ?
Infection • Inflammatory conditions • Neoplasia • Metabolic conditions Uraemia Acidosis Haemorhage
- Corticosteroids
- Marrow infiltration/fibrosis
- Myeloproliferative disorders
NEUTROPHILIA have two types …………………and ………………
Acute Neutrophilia and Chronic neutrophilia
Causes of Chronic neutrophilia?
Long term corticosteroid therapy
Chronic inflammatory reactions
Infections or chronic blood loss Infections
Less common organisms e.g poliomyelitis
Acute Neutrophilia is ………………………………
Mobilized rapidly by stress, suggested by adrenaline stress
test; due to reduced neutrophil adhesion
Causes of Acute Neutrophilia ?
Bacterial infection Stress Exercise Slower rise when cells are released from the bone marrow storage pool Steroid Infections
True or false
Steroids reduces the passage to the tissues
True
Leukemoid reactions have 3 important point to diagnosis?
neutrophilia with marked leucocytosis (>20 x 109/L)
NEUTROPHILIA >50,000 x109
The usual feature is the shift to the left of myeloid cells
Causes of Leukemoid reactions
include?
Infections
Marrow infiltration,
Systemic disease (e.g.: Acute liver failure)
NEUTROPENIA is ………………
Neutropenia is an absolute reduction in the number of
circulating neutrophils: Reduction in granulocytes:
Reduction in granulocytes can be …………………or ……………………
Decreased Production – Marrow.
• Increased destruction – drugs, immune
ا
Mention the mild and Moderate and Severe range to NEUTROPENIA and any ranges effect on agranulocytosis ?
Mild (1- 1.5 x 109/L)
Moderate (0.5 – 1 x 109/L)
Severe (<0.5 x 109/L) agranulocytosis
Sever is effect in agranulocytosis process
✅❌
Symptoms are present with the neutrophil count above 1 x 109/L
❌
Symptoms are rare with the neutrophil count above 1 x 109/L
commonest kind of infection is …………………
relatively uncommon kind of infection is …….
Bacterial infections are the commonest. Fungal, viral and parasitic infection are relatively uncommon.
Causes of Neutropenia?
• Racial • Congenital • Marrow aplasia • Marrow infiltration • Megaloblastic anemia • Acute infections Typhoid, Miliary TB, viral hepatitis • Drugs • Irradiation exposure • Immune disorders • Hypersplenism (splenomegaly)
