[Nasal conduction and ventilation: study of 30 children with food allergy before and after adenoidectomy].
Observed the results of an investigation on the trouble of breathing in 1350 children, looked at the trouble's frequence (450 positive and 400 dubious), the Authors studied the obstruction of the high and peripheral, air-ways and the associated auditive troubles in relation with aerial allergens and foods allergens.


METHODS
For the diagnosis of food's allergens: broncho-stimulation test by foods; rhinomanometry with Broms' formula, spirometry and Rresp exam, audiometric and impedentiometric exam.


RESULTS
About 30 children with air-ways obstruction and positive at the bronchostimulation test to food's allergens 7 were Prick and Rast positive to aeroallergens'; 12 showed total obstruction of nasal pipes and audiometric and impedentiometric troubles, 15 obstruction of one only nasal pipe, 3 absence of obstruction. At the spirometric check and of Rresp in the 63.3% of children was associated obstruction of peripheral air-ways and in the 26.6% laryngeal obstruction. The only nasal obstruction was present in 10% of children, in the 48% was associated to conjunctivitis. In 12 children with audiometric and impedentiometric damage who were adenoidectomized two months after the surgical intervention the nasal condition showed evident improvement but in 5 children after one year the nasal obstruction showed itself again. The food allergens exclusion caused disappearance of nasal, laryngeal and peripheral obstructive syndrome and normalization of audiometric and impedentiometric values in the adenoidectomized subjects and in 95% of staying children.
