Deep sighing breaths (blowing off CO2)
Metabolic acidosis
DKA
Renal failure

12

What is Kussmauls sign? What does this indicate? Give 3 causes

Rise in JVP on inspiration
Limitation of right ventricular filling
Constrictive pericarditis
Restrictive cardiomyopathy
Cardiac tamponade

13

How does Conn's syndrome cause high blood pressure?

Aldosterone increases sodium reabsorption
This causes increased water reabsorption leading to high BP

14

Which organism can cause a bilateral pneumonia in middle to old aged patients?

Legionella spp

15

What occurs in ACTH dependent Cushing's syndrome? Give 2 causes

Excess ACTH causes the excess cortisol production
Cushings disease: ACTH producing pituitary adenoma
Ectopic ACTH secretion

16

What occurs in a dexamethasone suppression test? What does this indicate?

Healthy: Presence of Dexamethasone provides negative feedback + suppresses ACTH release
Cushings: ACTH levels remain high

17

What occurs in ACTH independent Cushing's syndrome?

Hyperactive adrenals/ adrenal tumour making excess cortisol

18

How can ACTH independent and dependent tumours be differentiated?

Dependent: HIGH plasma ACTH, HIGH CORTISOL
Independent: LOW plasma ACTH, HIGH CORTISOL

19

Describe the levels of cortisol seen in low and high dose dexamethasone suppression tests in Cushings syndrome caused by adrenal tumours, ectopic secretion and pituitary tumours

Adrenal tumor
Low dose: no change
High dose: no change
Ectopic ACTH-producing tumor
Low dose: no change
High dose: no change
Pituitary tumor (Cushing's Disease)
Low dose: no change
High dose: normal suppression

Bilateral lower limb pitting edema suggests cardiac failure
Generalized peripheral pitting edema + swelling of eyelids indicates hypoalbuminemia

Cyp450 inhibitors
Increase action of Warfarin

29

How does Rifampicin interact with Warfarin?

Cyp450 inducer
Decreases action of Warfarin

30
