• High creatinine (uraemia)
• Low platelets
15
Q

Hereditary (3) and acquired (4) causes of haemolytic anaemia?

A

Hereditary
• Red cell membrane (hereditary spherocytosis)
• Enzyme deficiency (G6PD)
• Haemoglobinopathy (sickle cell disease, thalassaemia)

Acquired
• Autoimmune
• Drugs
• Infection
• MAHA
16
Q

What are small bowel folds called and what size would you expect the small bowel to be in obstruction?

A

Valvulae conniventes

> 3cm

17
Q

What are large bowel folds called and what size would you expect the large bowel to be in obstruction?

A

Haustra

> 6cm, > 9cm at caecum

18
Q

3 causes of hyponatramia with hypovolaemia?

A
  • Diarrhoea
  • Vomiting
  • Diuretics
19
Q

3 causes of hyponatraemia with euvolaemia and their tests?

A
  • Hypothyroidism - TFTs
  • Adrenal insufficiency - short synacthen test
  • SIADH - plasma + urine osmolality
20
Q

3 causes of hyponatraemia with hypervolaemia?

A
  • Cardiac failure
  • Cirrhosis
  • Nephrotic syndrome
21
Q
60 year old man
• Confused
• Cough
• Low sodium
• Low plasma osmolality (low sodium)
• High urine osmolality (high sodium)

Next most appropriate investigation and why?

A

CXR

• Lung cancer producing excess ADH

22
Q

What are almost all cases of hyponatraemia due to?

A

Rise in ADH - but this isn’t always ‘inappropriate’ as in SIADH

23
Q

Top 2 investigations for SIADH (and other cause)?

A
  • CXR - lung cancer
  • Brain CT - brain tumour

Drugs e.g. SSRI, TCA

24
Q

35 year old man with sweating, weight loss, nail separating from nail bed. What is the nail sign called and what is the cause? What are other causes of this sign?

A

Onycholysis caused by thyrotoxicosis

  • Trauma
  • Fungal infections
  • Psoriasis
