25
etiology of iron def anaemia
not enough iron diet, dec absorbtion of iron (coeliac disease, diarrhoea), pregnany, blood loss, parasites
25
etiology of iron def anaemia
not enough iron diet, dec absorbtion of iron (coeliac disease),
26
symptoms of anaemia iron
fatigue, tiredness, pale skin, headache, weakness, angina, palpitations, SOB, dysphagia, paresthesia
27
physical examination of iron anaemia
pale skin, mucosa, ulcers at mouth, changes in nails, tachycardia, systolic murmur, bleeding or the main disease
28
lab test for anaemia iron
dec HB, RBC, Ht, low mean corpuscular volume and mean corpuscular HB volume, dec iron, young RBC low, bleeding in stool and primary disease done. increase iron binding capacity as less intake of iron
29
complications of iron anaemia
IHD, cardiac or respiratory failure, atherosclerosis
30
Definition of vitamin B12 and folic acid deficiency anaemia
lack of it due to impared DNA replication and mitosis of hemopoietic cells as well as neuroepithelial cells
31
etiology of vit b12 and folic acid anaemia
absolute (diet) or relative (pregnant) dec intake of vitB12 dec absorbtion of B12 = autoimmune gastritis chronic diharroea parasites lack of pancreatic enzymes drugs (metformin)
32
symptoms of vit b12 and folic acid anaemia
same as iron and burning tongue (hunters glottis) dysphagia, ataxia, psychosis
32
Lab test vit B and folic acid anaemia
blood shows dec HB, RBC. MCV and MCHC inc, dec WBC, slightly inc iron and bilirubin (haemolysis), dec of vit b12 and folic acid
33
instrumental test for Vit B12 and folic acid anaemia
gastroscopy,
33
instrumental test for Vit B12 and folic acid anaemia
gastroscopy, and smear of blood marrow to see large hemopeotics
34
instrumental test for Vit B12 and folic acid anaemia
gastroscopy, and smear of blood marrow to see large hemopoietic cells
35
instrumental test for Vit B12 and folic acid anaemia
gastroscopy, and smear of blood marrow to see large hemopoietic cells
36
Acute leukaemia definition
malignant disease where cell clone from myeloid and lymphoid in bone marrow has fast reproduction and proliferates so normal hemopoeisis supressed and spreads to organs and tissues
37
Classification of acute leukaemia
acute myeloid leukaemia and acute lymphoblast leukaemia
37
etiology of acute leukaemia
genetic (chromosomal abnormalities), downs syndrome, infections (EBV), radioactivity
38
symptoms of acute leukemia
fatigue and exhaustion due to treatment to anaemia and infections with a fever bleeding in gums, pain in bones and joints, enlarged lymph nodes, loss of appetite and weight loss
39
physical examination of acute leukemia
impaired general condition, wax like skin and mucus, leukemids (skin lesion), enlarged lymph nodes and maybe spleen (ALL) or liver and spleen (AML)
40
Lab test of acute leukemia
blood: neutropenia, normocytic anaemia, blood smear shows blast cells showing difference enzymes and rods
41
instrumental tests for acute leukemia
bone marrow smeal with different staining, abdominal ultrasound, CAT to see spleen and liver enlargement or lymph nodes
41
instrumental tests for acute leukemia
bone marrow smeal with different staining, abdominal ultrasound, CAT to see spleen and liver enlargement or lymph nodes
42
complications of acute leukemia
infections and sepsis, haemorrage, brain damage?
43
Chronic myeloid leukaemia definition
uncontrolled proliferation of myeloid cells and cannot differentiate and suppresses other cell lines in bone marrow
44
etiology of CML (chronic myeloid leukaemia)
radiation, toxicity, genetic abnormality (philadelphia chromosome shorter 22 and longer 9) older males are more common
45
pathogenesis of CML
uncontrolled proliferation of myeloid cell branch to supress erythropoesis (anaemia) and then thrombocytopoesis (no clots) spread to other organs liver and spleen and many myeloid cells now in circulation to clot
46
symptoms of CML
fatigue and heaviness in abdomen, thrombotic incidents, fever sweating, pain in bones, weight loss, hemorrhagic diathesis
47
physical exam of CML
leukemids, pale skin, exessive pain in liver and spleen, infarction of spleen,
48
lab test of CML
bloodcount: inc WBC and dec RBC (anaemia) dec platelets blood smear shows immature myeloid cells check philedelphia (22 9)
49
instrumental tests of CML
bone marrow smear will show more myeloid cells compared to erythroblast abdominal ultrasound
50
complications of CML
blast crisis --> CML turns into myeloblast leukaemia thrombosis
51
Chronic lymphoid leukaemia definition
unctrolled proliferation of lymphocytes and supress other parts of hemopoiesis
52
Chronic lymphoid leukaemia definition
uncontrolled proliferation of lymphocytes and supress other parts of hemopoiesis
53
classification of CLL
chronic B and chronic T cell leukemia
54
etiology of CLL
EBV infection and chromosome anomalies Male more likely
55
symptoms of CLL
anaemia, serious infection, enlargement of lymph nodes, fatigue, weight loss, bleeding from gums
56
physical examination of CLL
pale skin and mucosa, luekmids
57
lab test for CLL
blood count shows inc lymphocytes and dec RBC and platelets, smear shows the nuclei of the immature lymphocytes specific genetic tests
58
instrumental tests of CLL
bone marrow spear, biopsy of lymph node, abdominal ultrasound and CAT to see enlarged spleen and lymph nodes
59
complications of CLL
severe infection and sepsis, lymphosarcoma (lymph nodes degenerate malignantly)
