Q

What is the most common source of Group A Streptococcus (GAS) infection leading to rheumatic fever in Australia?

A

= Pyoderma (GAS skin infection) (PPH 1 mark)

17
Q

What would be the effect of sensitivity and specificity of the Jones criteria as a diagnostic test for ARF if the number of major manifestations required to make a diagnosis is increased?

(1 mark)

A

Sensitivity would decrease, and Specifitiy would increase.

(PPH Total 1 mark)

18
Q

List two populations in which the positive predictive value of the Jones criteria is higher than in the general Australian population.

(2 marks)

A
  1. Australian Aboriginal people
  2. Indigenous people in New Zealand and Pacific Islands people
  3. People who have had a previous diagnosis of ARF
  4. People living in over-crowded conditions
  5. People from countries where ARF is common ie. low and middle-income countries in Asia, Africa, South America

(1 mark each to a maximum of 2 marks, PPH Total 2 marks)

19
Q

Which intervention is most affective in preventing children who have had ARF from developing rheumatic heart disease?

A

Monthly long-acting penicillin (or benzathine penicillin) prophylaxis.

(PPH 1 mark)

20
Q

What would be the best study type to establish what proportion of children who need this intervention are actually receiving it?

A

Case series

(PPH 0.5 marks)

21
Q

What would be the best study type to establish the reasons why children who need this intervention are or are not receiving it?

A

A qualitative study

(PPH 0.5 marks)

22
Q

A middle aged man with hypercholesterolaemia, and who has smoked all of his life presents to the emergency department with crushing retrosternal chest pain. His ECG is shown:

What is the diagnosis? Which part of the heart has been compromised? Which artery is most likely to have been occluded?

A
23
Q

He is treated with the tissue plasminogen activator (tPA).

Describe the mechanism of action of this agent and how it might assist this patient. List two contraindications to prescribing tPA.

A
24
Q

On the diagram, identify the structures labelled a through C.

List the contents of A.

List the contents of B.

A
  • A - Fibrous cap - Contents:
    1. Collagen
    2. Elastin

Q
A
26
Q

In what ways does challenging patient behaviour influence medical care approach?

(4 marks)

A
  • Modern medicine has recognised and highlighted the challenges and worked on communication skills (1 mark) through more structured approaches and developed tools and processes (0.5 marks) to give us insight and better set of skills to handle doctor/patient relationship in a positive way for better outcomes. (Max 1.5 marks)
  • Examples of new advancements:
    1. Use of Motivational interviewing skills
    2. Being empathetic
    3. Non-judgemental approach without stigmatising patient’s behaviour and attitudes.
    4. Avoid stereotyping patients
    5. Be mindful of own reactions to patients emotions
    6. Avoid threatening or manipulating patient’s behaviours
    7. Doctor’s awareness that frustration can affect decision making

(0.5 marks each up to 2.5 marks, PPD total 4 marks)

Q

In simple terms, what are the key ingredients of a ‘claim of negligence’? (4 marks)
