A

80%

26
Q

How is neuroblastoma treated?

A

27
Q

What percentage of patients with Wilm’s tumour are cured?

A

80%

28
Q

How is retinoblastoma treated?

A

Chemotherapy to shrink tumours
Laser treatment of the retina
Radiotherapy maybe used in more advanced disease

NOTE: 90% cure rate but many will be visually impaired

29
Q

Which antibiotics are used for suspected bacterial meningitis in children?

A

< 3 months = IV cefotaxime + amoxicillin
> 3 months = IV cefotaxime

30
Q

What is the definitive management for slipped upper femoral epiphysis?

A

Internal fixation across the growth plate

31
Q

Which type of fluid should be given for maintenance requirements in children?

A

0.9% NaCl + 5% dextrose

32
Q

How are dehydration corrections calculated when administering fluids?

A 
Usually given over 24 hours 
Give maintenance + % dehydration 
Weigh the child if possible (1 kg loss = 1000 mL)
Estimate clinically (e.g. each kg = 1000 mL, so 3% weight loss in 20 kg child = 3 x 200 mL = 600 mL)
33
Q

How should iron deficiency anaemia be treated?

A

Oral ferrous sulphate 200 mg tablets (2-3/day)

Continue for 3 months after iron deficiency has corrected

34
Q

What advice would you give to someone who is taking iron tablets for iron deficiency anaemia about side-effects?

A

May experience adverse effects (constipation, diarrhoea, faecal impaction)
Discomfort could be minimised by taking the iron supplement with food

35
Q

How should treatment for iron deficiency anaemia be monitored?

A

Re-check Hb after 2-4 weeks (expect 20 g/L rise)

FBC every 3 months for 1 year

45
Q

What medical treatment can be used for type 1 von Willebrand disease?

A

Desmopressin
