For the following patients with abdominal pain, choose the most likely diagnosis.
  
1) A previously well 10 month old baby presenting with drawing up of her legs with crying and some bloody runny stools. 
G. Intussusception      
Note:    
This is the right age group for intussception. It is often preceded by an URTI and it is thought that mesenteric lymphadenopathy may precipitate intussception. A red currant jelly-like stool is a late sign. In the older child, the cause of intussception may be HSP or lymphoma. 
2) A 4-year-old child, with poor eating habits, iron deficiency anaemia and intermittent colicky abdominal pain.     
C. Constipation 
Note:     
Constipation is common in children and should be managed aggressively to establish regular bowel habit quickly. 
3) A 2-year-old girl with nephrotic syndrome who has developed a fever and abdominal pain. 
A. Peritonitis 
Note:     
The causes of abdominal pain in nephrotic syndrome are peritonitis (usually pneumococcal), renal vein thrombosis and hypovolaemia.
