Successful treatment of dyshidrotic hand eczema using tap water iontophoresis with pulsed direct current.

The efficacy of tap water iontophoresis in treating palmoplantar hyperhidrosis has been sufficiently documented and has led to its extensive use in clinical practice. In order to test the efficacy of this treatment modality in cases of dyshidrotic hand eczema, 20 patients were treated with tap water iontophoresis in addition to two-sided steroid-free topical therapy in a randomized half-side-study. A special score for dyshidrotic eczema including objective and subjective criteria was developed to document the success of the therapy. Only those sides treated with tap water iontophoresis showed significant improvement. This significant effect of iontophoresis indicates the efficacy of this treatment in cases of dyshidrotic hand eczema.
