How behavior can condition allergic rhinitis

04.06.2008
A group of Swiss investigators has reported on a new conceptualization of the effects of behavioral conditioning in allergic rhinitis in the fourth 2008 issue of Psychotherapy and Psychosomatics.

Allergic symptoms can be induced by behavioral conditioning. However, the conditionability of antiallergic effects has not yet been studied. Thus, in this study the Authors investigated whether the effects of a histamine 1 (H1) receptor antagonist are inducible in patients suffering from house-dust mite allergy using a behavioral conditioning procedure.

During the association phase, 30 patients with allergic house-dust mite rhinitis received a novel-tasting drink once daily, followed by a standard dose of the H1 receptor antagonist, desloratadine, on 5 consecutive days.

After 9 days of drug washout, the evocation trial commenced: 10 patients received water together with an identically looking placebo pill (water group), 11 patients were re-exposed to the novel-tasting drink and received a placebo pill [conditioned stimulus (CS); CS group] and 9 patients received water and desloratadine (drug group).

During the association phase, desloratadine treatment decreased the subjective total symptom scores, attenuated the effects of the skin prick test for histamine and reduced basophil activation ex vivo in all groups. During the evocation trial, the water group, in which subjects were not re-exposed to the gustatory stimulus, showed a reduction in subjective total symptom scores and skin prick test results, but no inhibition of basophil activation.

In contrast, re-exposure to the novel-tasting drink decreased basophil activation, the skin prick test result and the subjective symptom score in the CS group to a degree that was similar to the effects of desloratadine in the drug group.

For the first time ever, a cloud of ultra-cold atoms has been successfully created in space on board of a sounding rocket. The MAIUS mission demonstrates that quantum optical sensors can be operated even in harsh environments like space – a prerequi-site for finding answers to the most challenging questions of fundamental physics and an important innovation driver for everyday applications.

According to Albert Einstein's Equivalence Principle, all bodies are accelerated at the same rate by the Earth's gravity, regardless of their properties. This...

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
