Q

Why can WCC be low in ALL?

A

As the damaged bone marrow produces defective white cells that don’t contribute towards the WCC (this is also why they get infections etc), hence the neutropaenia.

Q

What genetic change is Burkitt’s lymphoma associated with?

A

C-myc gene translocation

This leads to overexpression of the c-myc protein, which promotes cell growth and proliferation - key features of malignancy.

Q

Does HL cause an increase in the lymphocytes on blood tests?

No

But it can cause normocytic anaemia and eosinophilia.

Q

What do Auer rods on a blood film indicate?

A

AML

17
Q

TIBC in anaemia of chronic disease vs iron def anaemia?

A

Anaemic of chronic disease –> low/normal TIBC

Iron def anaemia –> raised TIBC

18
Q

Rituximab is used in combination with chemotherapy for a variety of types of non-Hodgkin’s lymphoma.

What receptor does this monoclonal antibody drug act against?

A

CD20 receptor (B lymphocyte antigen receptor)

19
Q

1st line mx of warm autoimmune haemolytic anaemia?

A

Steroids +/- rituximab

20
Q

What triad is seen in Felty’s syndrome?

A

1) RA
2) Splenomegaly
3) Low WCC (neutropenia)

This is an extra-articular manifestation of RA.

21
Q

What is a pepperpot skull a characteristic X-ray finding of?

A

Hyperparathyroidism (due to increased osteoclast activity).

Also myeloma.

22
Q

How can myeloma cause strokes?

A

Due to hyperviscosity (due to hyperparaproteinaemia)

23
Q

FBC results in CML?

A

an increase in granulocytes at different stages of maturation +/- thrombocytosis

24
Q

What condition is associated with ‘tear drop’ poikilocytes on blood film?

A

Myelofibrosis

25
Q

How do steroids affect WCC?

A

Cause neutrophilia

26
Q

Give 3 haematological causes of pyoderma gangrensoum

A

1) myeloproliferative disorders

2) lymphoma

3) myeloid leukaemias

27
Q

PT & APTT in APS?

A

PT - normal

APTT - prolonged

28
Q

Reticulocytes in beta-thalassaemia?

A

Raised

29
Q

HbA2 in beta thalassaemia trait?

A

Raised (>3.5%)

30
Q

What type of Hodgkin’s lymphoma carries the worst prognosis?

A

Lymphocyte depleted

31
Q

What can cause pancytopaenia 5 years post-chemotherapy/radiotherapy?

A

Myelodysplastic syndrome (MDS)

32
Q

What medications can exacerbate plaque psoriasis?

A
  • beta blockers
  • lithium
  • antimalarials (chloroquine and hydroxychloroquine)
  • NSAIDs
  • ACE inhibitors
  • infliximab
33
Q

Iron def anaemia vs anaemia of chronic disease:

1) serum iron
2) TIBC
3) serum ferritin

A

iron def:
1) decreased
2) raised
3) decreased

anaemia of chronic disease:
1) decreased
2) low/normal
3) normal/increased

34
Q

What can mixed anaemia (co-presentation of iron deficiency anaemia and B12 deficiency anaemia) cause?

A

Normocytic anaemia

35
Q

What is polychromasia?

A

There are more immature RBCs than what’s considered normal.

It’s a finding a peripheral blood smear.

Usually, it’s a sign that RBCs are being destroyed more quickly than the body can replace them (haemolytic anemia).

36
Q

Mx of acute pain crisis in sickle cell?

A

Morphine
