May refuse feeds
Vomiting may be bile stained
Abdo distension
Sausage-shaped mass may be palpated in the abdomen
Investigations for intussusception
‘Target’ sign on abdominal US (concentric echogenic and hypoechogenic bands)
Can also show complications such as free-abdominal air or presence of gangrene.
Management of intussusception
Rectal air insufflation or contrast enema (if child is stable)
Operative reduction indicated if:
- failure of non-operative management
- peritonitis or perforation is present

Fever
Sore Throat
Fatigue
Hepatomegaly and/or splenomegaly may sometimes be found on palpation
Management of Glandular Fever
Supportive
Advise against contact sports and heavy lifting for 1 month to minimise risk of splenic rupture.
What is Hypoxic Ischaemic Encephalopathy (HIE)?
Term for brain damage resulting from ante- or perinatal hypoxia
- lack of oxygen in foetal circulation results in poor supply of oxygen to brain
- ischaemia results in irreversible brain damage, both from primary neuronal death (immediate) and secondary reperfusion injury (delayed).
Presentation of HIE
Depends on the degree of neurological damage
- Mild: irritability
- Severe: hypotonia, poor responses, prolonged seizures
Normal Obs at Birth
HR: 110-170
RR: 35-55
Systolic BP: 50-70
Normal Obs at 12 months
HR: 80-140
RR: 30-40
Systolic BP: 70-100
Normal Obs at 3-5 years
HR: 80-130
RR: 20-30
Systolic BP: 70-110
Normal Obs at 6-11 years
HR: 70-120
RR: 16-25
Systolic BP: 80-120
Normal Obs at 12-18 years
HR: 60-100
RR: 12-22
Systolic BP: 100-120
Indications for Tonsillectomy
The indications for tonsillectomy in recurrent tonsillitis are
- seven or more episodes in a single year
- five or more episodes/year in two years
- three or more episodes/year in three years
What is Perthes Disease?
Avascular necrosis of the femoral head in children aged 4-8. Disruption of blood flow to the femoral head causes ischaemia.
Presentation of Perthes Disease
Gradual onset limp and hip pain.
Pain can also be referred to the knee.
Pain persisting for >4 weeks should raise suspicion
Diagnosis of Perthes Disease
Hip X-Ray: shows sclerosis and fragmentation of the epiphysis.
Management of Perthes Disease
Depends on extent of necrosis
<50% of the femoral head: can resolve with conservative measures like bed rest and traction.
> 50% of the femoral head: plaster cast keeping the hip abducted or osteotomy may be required. Poorer outcomes and carries ^risk for degenerative arthritis later in life.
What is necrotising enterocolitis?
Bowel of premature infant becomes ischaemic or infected
Risk factors for necrotising enterocolitis
Prematurity
Low birth weight (LBW)
Non-breast milk feeds
Sepsis
Acute hypoxia
Poor intestinal perfusion
Clinical Features of necrotising enterocolitis
First 3 weeks of life
Vomiting (may be bile streaked)
Bloody stools
Abdominal distension
Absent bowel sounds
Signs of systemic compromise inc. acidosis on blood gas
Investigations for necrotising enterocolitis
Abdo X-Ray
- dilated bowel loops
- Pneumatosis intestinalis (gas within bowel wall)
- portal venous gas
- Pneumoperitoneum
Management for necrotising enterocolitis
NG tube
Broad spectrum Abx
Total parenteral nutrition to rest bowel
IV fluids and ventilation
Surgery to resect necrotic section of bowel may be necessary –> essential if bowel perforation
Complications of necrotising enterocolitis
Fatal in 1/5 cases
