Unit 1360: Comprehensive Hematology

1. Introduction to Hematology

• Definition and scope of hematology
• Importance of studying blood, blood-forming organs, and blood disorders
• Historical perspective and advances in hematology

2. Blood Composition

2.1 Components of Blood

• Red Blood Cells (Erythrocytes)
• White Blood Cells (Leukocytes)
• Platelets (Thrombocytes)
• Plasma

2.2 Functions of Blood Components

• Oxygen transport
• Immune defense
• Hemostasis
• Nutrient and waste transport

3. Hematopoiesis

• Definition and overview of hematopoiesis
• Sites of hematopoiesis (fetal and adult)
• Stem cells and differentiation pathways
• Regulation of hematopoiesis

4. Red Blood Cell Disorders

4.1 Anemia

• Definition and classification (nutritional, hemolytic, aplastic, etc.)
• Pathophysiology and clinical features

4.2 Polycythemia

• Types: primary and secondary
• Causes and clinical implications

4.3 Hemolytic Disorders

• Mechanisms of hemolysis
• Examples: sickle cell disease, thalassemias

5. White Blood Cell Disorders

5.1 Leukemias

• Classification (acute vs. chronic, myeloid vs. lymphoid)
• Pathogenesis and clinical manifestations

5.2 Lymphomas

• Hodgkin vs. Non-Hodgkin lymphoma
• Clinical presentation and diagnosis

5.3 Other Immune System Disorders

• Neutropenia
• Leukocytosis

6. Platelet Disorders

6.1 Thrombocytopenia

• Causes (immune, drug-induced, marrow failure)
• Clinical features and diagnosis

6.2 Thrombocythemia

• Essential thrombocythemia and secondary causes

6.3 Bleeding Disorders Related to Platelets

• Qualitative platelet defects
• Von Willebrand disease overview

7. Hemostasis and Coagulation

• Overview of hemostasis phases: vascular, platelet, coagulation
• Clotting cascade: intrinsic, extrinsic, and common pathways
• Coagulation factors and their roles
• Natural anticoagulants and fibrinolysis

8. Blood Transfusion and Blood Banking

• Blood groups and typing (ABO, Rh systems)
• Crossmatching and compatibility testing
• Indications and complications of blood transfusion
• Overview of blood banking procedures and storage

9. Hematologic Malignancies

• Classification and pathophysiology
• Diagnosis: clinical and laboratory features
• Treatment modalities: chemotherapy, radiotherapy, bone marrow transplantation

10. Hematologic Tests and Diagnostics

• Complete Blood Count (CBC): interpretation and significance
• Peripheral blood smear analysis
• Coagulation studies: PT, aPTT, INR
• Bone marrow aspiration and biopsy: indications and procedure

Note: Each section will include case studies, clinical correlations, and laboratory data interpretation exercises to reinforce theoretical knowledge.
