Leukopenia :
Deficient WBC , Decrease of neutrophils is most common etiology .
![Page 3: BLEEDING DISORDERS Bleeding Disorders... · BLEEDING DISORDERS By Diaa Ahmed Elsaied Lecturer OMFS Minia University Leukopenia : Deficient WBC , Decrease of neutrophils is most common](https://reader035.vdocuments.us/reader035/viewer/2022062415/5fd4f0965149322bbe5276c5/html5/thumbnails/3.jpg)
Physical finding are increased risk microbial infection.
Increased risk of fungal infection.
Management include :
-- Prophylactic Antibiotic.

Elevated percentage of immature WBC in peripheral circulation.
It is cancer of the WBCs that affects the bone marrow and circulating blood. It involves exponential proliferation of a clonal myeloid or lymphoid cell.
Symptoms includes:
Nausea – Fever – Weight Loss
Fatigue – Malaise - Epistaxix
Liver or spleen enlargment Bone pain & tenderness
Oral manifestation includes:
Gingival Enlargement & ulceration
Pain Erythema & oral infection

The cause of leukemia is unknown
Increased risk is associated with large doses of ionizing
radiation, certain chemicals(benzene), and infection with
specific viruses [EPV] and human lymphotropic virus
[HTLV]-1
Smoking & exposure to electromagnetic
Genetic factors may cause cytogenetic abnormalities that
affect transcriptional cascades of myeloid precursor cells.

Acute leukemia
Result from accumulation of immature , functionless WBCs in the marrow & blood
1. Acute myeloid leukemia (AML)
2. Acute lymphocytic leukemia (ALL)
Chronic leukemia
Have slower onset which allows production of larger numbers of more mature, functional cells
1. Chronic myeloid leukemia (CML)
2. Chronic lymphocytic leukemia (CLL)

Bone marrow test
1. Bone marrow aspiration :
Remove a liquid marrow sample
2. Bone marrow biopsy
Lumbar puncture:
Removes a small amount of
cerebrospinal fluid (CSF) from the space around the spine

Chemotherapy
The main treatment for many kinds of leukemia
It has 3 phases:
1- Induction
2- Consolidation
3- Maintenance
Radiation therapy
To prevent leukemia from spreading to, or treat leukemia that has spread to, the central nervous system (CNS)
Bone marrow transplant

Anemia is a decrease in the total amount of red blood cells (RBCs) or hemoglobin in the blood, or a lowered ability of the blood to carry oxygen.
Laboratory definition:
Reduction in haemoglobin concentration
below normal
WHO criteria:
Males Hgb <13 gm/dl,
Females Hgb <12gm/dl

Medical & family history & perform a physical exam.
Complete blood count (CBC):- A CBC is used to count the number of blood cells in a sample of your blood. For anemia the levels of the red blood cells contained in the blood (hematocrit) and the hemoglobin in the blood is interested.
Tests for internal bleeding:- To ensure that internal bleeding is causing anemia, may also perform an endoscopy. These test can help identify sources of gastrointestinal bleeding.
![Page 15: BLEEDING DISORDERS Bleeding Disorders... · BLEEDING DISORDERS By Diaa Ahmed Elsaied Lecturer OMFS Minia University Leukopenia : Deficient WBC , Decrease of neutrophils is most common](https://reader035.vdocuments.us/reader035/viewer/2022062415/5fd4f0965149322bbe5276c5/html5/thumbnails/15.jpg)
Treatments for anemia depend on cause and severity. Vitamin supplements given orally (folic acid or vitamin B12) or intramuscularly (vitamin B12) will replace specific deficiencies.
Anemia treatment depends on the cause.
a) Iron deficiency anemia
b) Vitamin deficiency anemia
c) Anemia of chronic disease
d) Aplastic anemia
e) Anemia associated with bone marrow disease
f) Hemolytic anemia
g) Sickle cell anemia
![Page 16: BLEEDING DISORDERS Bleeding Disorders... · BLEEDING DISORDERS By Diaa Ahmed Elsaied Lecturer OMFS Minia University Leukopenia : Deficient WBC , Decrease of neutrophils is most common](https://reader035.vdocuments.us/reader035/viewer/2022062415/5fd4f0965149322bbe5276c5/html5/thumbnails/16.jpg)
Iron deficiency anemia:- Treatment for this form of anemia usually involves taking iron supplements & making changes to your diet.
• Diet as red meat, dark green leafy vegetables, dried fruits, nuts, iron-fortified cereals.
Vitamin deficiency anemia:- Treatment for folic acid & B-12 deficiency involves dietary supplements & increasing these nutrients in diet.
•If your digestive system has trouble absorbing vitamin B-12 from the food you eat, you may need vitamin B-12 shots.
