Welcome Message We are pleased to announce the Update in Paediatric Respiratory Diseases 2009. The first Update in 2007 was well attended and we received extremely positive feedback from the participants. The conference will cover a wide range of interesting and challenging topics. We are delighted that a panel of world experts will join us and share their valuable and enlightening experiences at this meeting. We sincerely invite you to join us: to learn, to share your knowledge, to meet old friends and to make new ones. Albert Li & Simon Lam Co-chairman Organising Committee
