Aim of study (acc. to author)

To study the effect of microwave radiation in patients with atopic eczema/dermatitis syndrome (AEDS) to determine whether microwave radiation could alter the allergen-induced skin wheal responses and plasma levels of substance P and vasoactive intestinal peptide (VIP).

Setup The mobile phone was tied around the neck by a string and placed 4 cm below the chin.
Additional info All 26 patients were studied at the same time as a group. Patients viewed a video during exposure ("mobile phones calling without sound") or sham exposure ("mobile phones without calling"). Exposure and following control studies were one week apart and single-blind.

Main outcome of study (acc. to author)

The results indicate that microwave radiation from mobile phones may enhance allergen-induced wheal responses in association with release of substance P and vasoactive intestinal peptide. This finding may be useful in elucidating the pathophysiology and treatment of AEDS.
