Blood features of Hereditary Spherocytosis
Type of haemolytic anaemia
Can present at any age
Increased unconjug bilirubin Increased urinary urobilinogen Increased LDH Increased reticulocytes Increased MCHC Decreased haptoglobin
VTE RFs
Surgery Trauma Immobility Malignancy OCP/HRT Pregnancy IBD Nephrotic syndrome Obesity Inherited thrombophilia: FVL, pCS deficiency, Antithrombin deficiency
6mo old girl with FTT, anaemia, frontal bossing
Dx and Rx
Cooley’s Anaemia AKA. Beta thalassaemia MAJOR (px in first year of life)
Lifelong transfusion + desferrioxamine
NB. Betathal minor is asymptomatic carrier state
Betathal intermedia has anaemia and moderate splenomegaly
Disoder causing bleeds into joints and muscles eg. massive haemarthrosis
Haemophilia
In warfarin toxicity, when to give vitamin K?
If minor bleeding present
OR
If INR >8
target cells, other names and causes?
codocytes
leptocytes
Mexican hat cells
Thalassaemia
Iron deficiency
Splenectomy
Liver disease
Auer rods, Dx?
AML
Reed-Sternberg cells, Dx?
Hodgkins lymphoma
APL Rx + if pregnant?
Warfarin
If pregnant: Aspirin + LMWH
40-60yo
abdo pain
massive splenomegaly
WCC HIGH +/- low Hb/platelets
Dx and Rx
CML
(Ph chromosome t(9:22) in 80%)
Rx:
Chemo (imatinib)
SCT
65+yo w/l painless LNopathy lymphocytosis HSM
Dx and Rx
CLL - often asymptomatic
Rx: no curative option
Chlorambucil
Fludarabine
Monitor if no symptoms
Smear cells
CLL
Lymphocytes with ruptured cell membranes
Teardrop cells
Myelofibrosis
immature erythroid and myeloid cells also seen
Myelofibrosis important complication
10% risk transformation to AML
Mycoplasma complications
Cold agglutinin (IgM) haemolytic anaemia Erythema nodosum Erythema multiform Mycocarditis Meningo-encephalitis
Ileal resection + hypersegmented polymorphs
B12 deficiency
folate also causes hypersegmented polymorphs but is instead digested in duodenum and proximal jejunum
What is a paraproteinaemia and examples
Presence of immunoglobulins produced by single clone of plasma cells
eg. MM, primary amyloidosis, Waldenstroms macroglobulinaemia, heavy chain disease
