HAEMATOLOGY Flashcards
hypersegemented neutrophils
macrocytic anaemia - vitB12 or folate deficiency
management of vitB12 def anaemia
1g IM hydroxycobalamin 3 times a week for 2 weeks
then every 3 months
if dietary can give oral oxocobalamin daily
management for folate def anaemia
oral folic acid daily for 4 months
anaemia symptoms
neuro symptoms
lemon tinge/mild jaundice
typically middle-old age female
pernicious anaemia
pancytopenia normocytic normochromic anaemia thrombocytopenia leukopenia (anaemia symptoms, infections and bleeding)
aplastic anaemia
definitive investigation for aplastic anaemia
biopsy - empty marrow or dry tap
management of aplastic anemia
remove any toxinx/meds/cause
if under 50 = stem cell transplant
if over 50 = immunosuppression with cyclosporine and glucocorticoids
severe cases = blood transfusion and GCS factor
angina dyspnoea tachycardia jaundice splenomegaly gallbladder involvement \ ulcers
haemolytic anaemia
investigation for haemolytic anaemia
coombs test - positive
spherocytes on blood film
IgM = cold HA
IgG = warm HA
management of haemolytic anaemia
warm = steroid, immunosuppression and then splenectomy cold = no tx
if severe = plasmapheresis
anaemia, neonatal jaundice/dark urine, splenomegaly, gallstones, intravascular haemolysis/haemoglobinuria
triggered by broad bean consumption
G6PD deficiency
Investigations of G6PD def anaemia
diagnostic = G6PD enzyme assay
also heinz bodies and bite/blister cells on blood film
management of G6PD def anaemia
avoid triggers
crisis = rehydrate and blood transfusion
25yrs anaemia neutropenia thrombocytopenia splenomegaly bone pain
AML
management for AML
chemo
allogenic SCT
philadelphia chromosome 60-70yrs marked splenomegaly = abdo pain B symptoms and WBC at different stages of maturation
CML
management of CML
imatinib
(hydroxyurea, a-interferon and allogenic BM transplant)§
child, boy anaemia thrombocytopenia = brusing, bleeding or petechiae bone pain hepatosplenomegaly
ALL
management of ALL
chemotherapy +/- immunotherapy
