  • Title: [Physiopathology of acetylcholine delayed blanch in atopics. Thermographic study (author's transl)].
    Author: Grosshans E, Selig D, Quenneville Y, Gautherie M.
    Journal: Ann Dermatol Venereol; 1977; 104(6-7):453-57. PubMed ID: 921179.
    Abstract:
    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.
