SR Print(0) ID 1182917049 T1 Preschool Wheeze: Diagnosis and Management T2 Rudolph's Pediatrics, 23e YR 2018 FD 2018 PB McGraw-Hill Education PP New York, NY SN 9781259588594 LK accesspediatrics.mhmedical.com/content.aspx?aid=1182917049 RD 2024/03/29 AB Preschool wheeze affects at least one-third of all children younger than 5 years old, and a disproportionate number of preschool children use healthcare resources for wheezing episodes compared to school-aged children with asthma. However, despite this high prevalence, it remains a significant management challenge. Establishing a diagnosis is difficult, with almost complete reliance on accurate parental symptom reporting, and there are no objective tests to assess lung function or airway inflammation. These patients have a relatively poor response to traditional asthma medications, and we cannot predict or prevent who will progress to asthma.
