[The environment and perennial rhinitis in the child]

In assessing the importance of the "allergen eviction" factor in the treatment of infantile allergies, the authors begin an inventory of those elements in the environment that concern perennial rhinitis. From 200 observations of allergic children (all mixed diagnoses) they found 21 observations of rhinitis alone, predominantly boys. The environments of two groups (all allergics--rhinitis alone) were compared. No difference for: Home, country, town heating allergens found. Found significant differences for the type of house new-old those elements of domestic comfort (carpets, feather beds, aeration, soft toys) agreement between the results of tests and the environment domestic animals or permanent proximity. Found fundamental differences for psychological environmental factors (absent in rhinitis). It seems that perennial rhinitis probably arises from abundance of domestic antigens more than for the other allergic manifestations, as the nose is the first filter to receive foreign particles.
