This volume of "Agents and Actions Supplements" provided a challenge to
the editors, the authors and the publisher. It was our aim to complete
the book in advance of the lectures to be given at the "International
Symposium on Asthma and Allergic Diseases in Childhood", in Berne,
Switzerland, on March 25th-27th, 1993. This symposium commemorates the
10th anniversary of the Swiss Association of Parents of Asthmatic and
Allergic Children. The incidence of asthma and allergies generally is on
the increase and demands everyone's attention, including that of
physicians, researchers, allied health professionals and parents. There
have been no recent breakthroughs in our understanding of asthma
pathogenesis or treatment. However, forms of treatment, pathogenetic
insights and public awareness are undergoing rapid changes as our
knowledge of atopic diseases increases. For this reason we chose the
title "Update on Childhood Asthma". The purpose of the papers is to
summarize recent research results, to provide an update on the current
approach to therapeutic interventions and to alert readers to the
psychosomatic aspects of asthma. Whether the state of knowledge has
already changed while you are holding this book in your hands is not so
much dependent on a delay in publishing but on the speed of appearance
of new research results. Fortunately, our ambitious target to edit the
proceedings in advance of the conference has been successful. This was
only possible because of the timely submission of papers, the speed of
publication and the enthusiasm of the editors.
