[Aspiration bronchopneumopathies].
Diagnosis of pulmonary disease due to inhalation (PDI) is based on the assumption that not all paediatric pulmonary disease is attributable to infection. Moreover, an accurate investigation of all typical signs of PDI is necessary: drooling, pouring of food from the nose, choking, frequent vomiting and regurgitation. Specific aetiological diagnosis is not difficult when PDI represents only the epiphenomenon of well defined diseases which have disturbed deglutition (e.g. premature birth, cerebral palsy, muscle disease). It is difficult but more important to find the cause of dysphagia when dysphagia itself represents the first sign of dysfunction of the autonomic nervous system (e.g. familial dysautonomy). There are different PDI due to oesophageal dysphagia, e.g. the anomalous artery which presses the oesophagus against the trachea, oesophageal duplication, achalasia. The most frequent cause is gastro-oesophageal reflux, although recently its role in producing symptoms at night in the asthmatic child in much less. Gastro-oesophageal reflux is increased by the Beta2, agonists, the corticosteroids and theophylline. Therefore these drugs, especially theophylline, have to be used with discretion, also if gastro-oesophageal reflux is only suspected (e.g. frequent vomiting by the infant). Anomalous communication between the oesophagus and airways, particularly the laryngotracheo-oesophageal cleft and the isolated tracheoesophageal fistula, are rare diseases and difficult to diagnose. Therefore diagnosis can be delayed for months or even years. Prognosis is extremely variable: repeated inhalation will, however, cause diffuse interstitial fibrosis or, more rarely, a bronchiectasic lesion.
