[Physiopathology of acetylcholine delayed blanch in atopics. Thermographic study (author's transl)].
Controversy subsists about interpretations of "delayed cholinergic blanch" in atopic dermatitis. A physical approach of this vasomotor phenomenon using infrared and cholesteric thermography and direct recording of skin temperature shows that the delayed blanch is hyperthermic and cannot be the effect of a paradoxal cholinergic vasoconstriction. In the light of the beta-adrenergic blockade theory of Szentivanyi a new physiopathological interpretation is proposed.
