Haematology summary 19


Chapter 19 in haematology (Hodgkin lymphoma)summary

-Lymphoma are a group of diseases caused by malignant lymphocytes that accumulation in lymph nodes and cause lymphoadenopathy.

-The major subdivision of lymphomas ia into hodgkin and this is based on the presence of Reed-strenberg cells in hodgkin lymphoma.

-Reed-strenberg cells are neoplastic B cells but most cells i the lymph node are reactive inflammatory cells.

-The usual clinical presentation is with painless asymmetrical lymphadenopathy- most commonly in the neck.

-Constitutional symptoms of fever,weight loss and sweating are prominent in patients with widespresd disease.

-Blood tests may show anaemia, neutophilia and rasied erythrocyte sedmentation rate (ESR) or lactic dehydrogenase (LDH).

-Diagnosis is made by histological examination of an excised lymph node and there are four subtype of disease .

-Staging of the disease is important for determining treatment and prognosis history, examiantion, blood test ,CT and PET scan are typically used.

-Treatment is with radiotherapy, chemotherapy or acombination of both. The choice depends on the stage and grade of the disease .

-The response to treatment can be monitored by CT and PET scans.disease relapse can be treated with chemotherapy sometimes with stem cells transplantion.

-The prognosis is excellent and over 85% of patients can expect to be cured.late side effects of treatment are a concern.

Haematology summray 8

Chapter 8 in Haematology (Granulocytes and monocytes) summary -Granulocytes include neutrophils (polymorphs),eosinophils and basophils.They are made in the bone marrow under the control of a variety of growth factors   and have a short lifspan in the blood stream befor entring tissues. -Phagocytes (neutrophils and monocytes) are the   body's main defence against bacterial infection.Neutrophil leucocytosis occurs in bacterial infection and in other types of inflammation.Neutropenia , if severe, predisposes to infection. It may be caused by bone marrow failure, chemotherapy or radiotherapy drugs. -Eosinophilia is most frequently caused by allergic diseases, including skin diseases,parasitic infection or drugs. Ti can be caused by clonacal increase in eosinophils termed chronic eosinophil leukamia or an idiopathic condtion, often associted with tissue damage. -Detects of function of neutrophils and monocytes may affect their chemotaxis, phagocytesis oe killing. ...

Chapter 9 in Haematology (White cells: lymphocytes) summary -Lymophcytes are immunologically comptent white cells that are involved in antibody production   (B cells) and with the body's defence against viral infection or other foreign invasion (T cells). -They arise from haemopoietic stem cells in the marrow, T cells being subseqently processed in the thymus. -B cells secrete gammaglobulin antibodies specific for individual antigens.T lymphocytes are further subdivided into helper (CD4 + ) and cytotoxic (CD8 + )cells .They recognise peptides on HLA atigens.Natural killer cells are cytoxic CD8 + cells that kill target cells with low expression of HLA molecules. -The immune response occurs in the germinal centre of lymph nodes and involves B-cell and T-cell proliferation, somatic mutation, selection od cells by recognition of antigen on antigen-presenting cells and formation of plasma cells (which secrete immunoglobulin)or memory B cells. -Immunoglobulins inc...

Heamatology summary 12

Chapter 12 in Haematology (Haematoloical malignancy: managment) summary -Progress in the treatment of haemopoietic malignancies has been the result of improvemnets in both supportive therapy and speicific tumour treatments. -Supportive treatments often include : insertion of a central nevous catheter; Appropriate use of red cell and platelet transfusions; Early administration of drugs to traet infection;Otimiziation of the blood coagulation system Drugs to reduce side effects such as nausea or pain;Psychological support. -Gram-positive skin organisms such as staphyloccus are common infections and often colonize central venous catheters. -Gram-Negative bacteria are usually derived from the gut and and can cause severe septicemia. -The use of air filters,handwashing and antibiotics can reduce infection rates . -Neutropenic patients who developa fever should be treated urgently with broad-spectrum antibiotics. -Herpes viruses are a common cause of infection in ...
