[Peroral nickel provocation in nondyshidrosiform and dyshidrosiform nickel eczema].

The flare-up of pompholyx-type nickel eczema induced by oral nickel challenge has been dealt with in several publications. To compare the reactivity of non-pompholyx and pompholyx-type nickel eczema, we challenged three groups of female volunteers (7 with non-pompholyx-type and 12 with pompholyx-type nickel eczema plus 10 control subjects without nickel allergy) with an oral dose of 2.5 mg nickel.

["Aqua-SUP" in chronic palmoplantar dermatoses].

In 11 of 15 patients suffering from chronic dermatoses of the palms and soles (psoriasis inversa, palmoplantar pustulosis, palmoplantar hyperkeratotic eczema and idiopathic pompholyx), an improvement was achieved with "aqua-SUP" therapy. Trials using this therapeutic modality, which is a combination of balneotherapy and selective UV phototherapy (SUP), have only rarely been reported so far. In addition, five patients received internal medication (mainly aromatic retinoid) that had previously not been effective enough, three of them in combination with local corticosteroids.
