[Allergic aspects of juvenile asthma].

In children, wheezing is not necessarily related to allergy. Without being asthmatic, a child may suffer from asthmatiform dyspnea, especially in cases of respiratory infection. It may be difficult to decide whether the patient has benign "wheezy bronchitis" or is exhibiting the first symptoms of asthma. It appears that viral infections may play a significant role in the development of respiratory allergy in atopic subjects.
