I talk with another friend and colleague from my time at Yorkhill.  He tells us something about his career since he left paediatrics and we discuss a child we both came across who had a condition known as Cystic Fibrosis. There is a short update about cystic fibrosis and then we discuss a premature baby who did very well and for whom John has very long term 'follow-up' information. We discuss changes in medicine, progress and the importance of team working.
