ABSTRACT
History Mohammed is a 3-month-old boy, brought to a paediatric rapid referral clinic because of persistent noisy breathing. He was born in the United Kingdom at term, after an uneventful pregnancy, and is the fifth child of non-consanguineous Somalian parents. His birth weight was 3.7 kg (75th centile). Since he was a few weeks old, he has had noisy breathing, which has not affected his feeding, and his parents were repeatedly reassured that it would get better. He has continued to have intermittent noisy breathing, especially when agitated, and sometimes during sleep. Over the past few days, his breathing has been noisier than usual. Otherwise he has been well without any fevers. All of his siblings have recently had coughs and colds.
