The article discusses research being done on the use of corticosteroids for the treatment of croup. It references a study by Ausejo et al published in a 1999 issue of the "British Medical Journal." Laryngotracheobronchitis or commonly known as croup is a common upper respiratory illness in children. The study is a meta-analysis involving 24 randomized controlled trials that examined the effectiveness of corticosteroids for children with croup. Results showed that a significantly greater decrease in croup symptoms was observed after 6 and 12 hours of corticosteroid treatment.
