Q

INR Targets

  • AF/cardioversion

A

INR Targets

  • AF/cardiov 2.5
  • MI 2.5
  • Single DVT 2.5
  • Recurrent DVTs 3.5
  • Prosthetic valve 3.5

Lower = more clots
INR within 0.5 of target is satisfactory

Rule of thumb - everything except recurrent DVTs/PEs and some prosthetic valves is 2.5 target!

Q

How to differentiate between acute haemolytic transfusions & febrile non-haemolytic transfusion reactions? (In exams!)

Febrile non-haemolytic more common

b. Because it secrete Thrombomodulin
c. Because it secretes Von Willebrand factor

A

b. Because it secretes Thrombomodulin

82
Q

Which feature is characteristic of acute lymphoblastic anaemia (ALL)

a. anaemia and thrombocytopenia
b. neutropenia
c. macrocytosis
d. raised lymphocytes
e. eosinophilia

A

b. neutropenia

Patients with ALL can have high, normal, or low whitebloodcell (lymphocyte) count (WBC), but will usually exhibit neutropenia.

Extra info: If this question had asked about CLL instead, it is commonly associated with granulocytopenia and smudge cells.

83
Q

Which clotting factor falls most rapidly after administering warfarin?

A

Factor VII

Plasma half-life of vitamin K-dependent factors 
II = 72h
VII = 4-6h
IX = 48 hours
Protein C = 6-7 hours
84
Q

A patient has a massive splenomegaly, and JAK2 V617F mutation with a leucoerythroblastic picture and tear-drop poikilocytes. What do they have?

A

Myelofibrosis (also known as osteomyelofibrosis)

JAK2 mutation occurs in 97% of Polycythaemia Vera, 50-60% of primary myelofibrosis [1].
Raised levels of Poikilocytes (also known as da-cro-cytes (Remember they are the ‘da-cry-cells’)), which are tear drop shaped, – are characteristically found in Beta Thalassemia major and myelofibrosis – resulting in splenomegaly. Therefore the only diagnosis that matches the question is Myelofibrosis (Pathophysiology = Myelo-fibr-osis = Bone marrow-fibrin-formation, or (read backwards) process of formation of fibrin in bone marrow).

85
Q

An African man, with Burkitt’s lymphoma is given Rasburicase. He develops haematuria with irregularly contracted cells. What is the cause?

A

Glucose-6-phosphate dehydrogenase deficiency

86
Q

A patient required an aortic valve replaced 3 months ago. They have now come back a few weeks later with jaundice, Hb-urea (haemoglobinuria), and raised reticulocytes. What is the cause?

A

Mechanical Haemolytic Anaemia

Q

Transfusion reactions

●	Allergic reaction
