Does a diagnosis of cystic fibrosis change the management of the respiratory infection?
Children with CF are at risk of recurrent and persistent bacterial infections due to thick mucus in lower airways- this damages bronchial walls- causes bronchiectasis and abscess formation.
Therefore antibiotics would be needed in this case, as well as physiotherapy for airway clearance, nebulised DNase or hypertonic saline may decrease the viscosity of the sputum and aid clearance.

- Coeliac disease or cow's milk protein intolerance
- GE
- Chronic constipation- overflow
- Lactose intolerance
- IBD
- Cholestatic liver disease
78
What happen in overflow diarrhoea?
Chronic constipation causes the rectum to be distended and cause a loss of feeling of needing to defecate
Involuntary soiling occurs as contractions of the full rectum inhibit the internal sphincter- causing overflow
Recovery of normal rectal size and sensation may take a long time
79
What is the management of constipation?
- Constipation arising acutely in young children e.g. acute febrile illness, usually resolves spontaneously or with the use of mild laxatives and extra fluids. Encourage a balanced diet
- In more long-standing constipation, the rectum becomes overdistended, with a subsequent loss of the feeling of needing to defecate, leading to involuntary soiling.
- Macrogol laxative e.g. polyethylene glycol and electrolytes (Movicol paediatric plain)- 2 weeks 1st line (osmotic laxative)
- Stimulant laxatives are the next step (e.g. senna or picosulphate) +/- osmotic laxative (e.g. lactulose) 2nd line
If there is no success, consider enema (+/- sedation) or manual evacuation under GA

81
What is Hirschprung's disease?
The absence of ganglion cells from the myenteric and submucosal plexuses in part of the large bowel results in a narrow, contracted segment. The abnormal bowel extends from the rectum for a variable distance proximally, ending in a normally inverted, dilated colon.
More common in boys, and is associated with Downs syndrome.
82
How does Hirschprung's disease present?
Usually in the neonatal period with intestinal obstruction heralded by failure to pass meconium within the first 24 hours of life.
Abdominal distension and later bile-stained vomiting develop. Occasionally, infants present with severe life-threatening Hirschsprung enterocolitis during the first few weeks of life, sometime due to Clostridium Difficile infection.

117
The blood glucose in a neonate with RDS has dropped to 2.1. Why is this likely to have happened?
Increased work of breathing and decreased feeds means blood sugar decreases.
Also preterms already have deficiency of glycogen stores.
Give 2.5mls/kg of 10% dextrose IV and check BG after 30 mins
118
