Answer 2

RSV

Question 3

Features of bronchiolitis

Answer 3

coryzal symptoms (including mild fever) precede:

Question 5

Ix for bronchiolitis

Answer 5

immunofluorescence of nasopharyngeal secretions

Question 6

Management of bronchiolitis

Answer 6

Management is largely supportive:
1. humidified oxygen is given via a head box (if O2 sats < 92%)

2. nasogastric feeding may be needed if children cannot take enough fluid/feed by mouth
3. suction is sometimes used for excessive upper airway secretions

3. stool culture

Question 10

Management of HUS

Answer 10

1. treatment is supportive e.g. Fluids, blood transfusion and dialysis if required
2. No Abx, despite the preceding diarrhoeal illness in many patients
3. plasma exchange is reserved for severe cases of HUS not associated with diarrhoea
4. eculizumab (in adults)

Answer 21

hyponatraemia secondary to the dilutional effects of excessive water retention.

Question 22

Management of SIADH

Answer 22

1. correction must be done slowly
2. fluid restriction
3. demeclocycline: reduces the responsiveness of the collecting tubule cells to ADH
4. ADH (vasopressin) receptor antagonists have been developed

Absent medial arch on standing

Typically resolves between the ages of 4-8 years

Question 31

Management of perthes'

Answer 31

1. To keep the femoral head within the acetabulum: cast, braces 2. If less than 6 years: observation 3. Older: surgical management with moderate results 4. Operate on severe deformities
