Since the first edition of Allergic and Vasomotor Rhinitis: Clinical Aspects was published seven years ago, there has been considerable progress in both the diagnosis and treatment of allergic and non-allergic rhinitis. This updated version of the work combines European and North American approaches to the management of allergy and rhinitis. Before writing their chapters, the contributors discussed their topics at a workshop in Copenhagen. Written primarily for the practising clinician, the work also includes recent research data.
