After discussing the causes and immunopathology of allergic rhinitis, the 
authors describe the most frequently used diagnostic tests, confirming the 
validity of PRICK TEST, PRIST, RAST, and TNP. As for treatment, they stress the 
special importance of vaccines for specific therapy and of drugs such as 
ketotifen and sodium cromoglycate for aspecific rhinitis and for those forms 
which have not benefited from vaccination.
