[Physiopathology of acetylcholine delayed blanch in atopics. thermographic study (author's transl)]. 1977

E Grosshans, and D Selig, and Y Quenneville, and M Gautherie

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.

UI MeSH Term Description Entries
D003876 Dermatitis, Atopic A chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus. It is manifested by lichenification, excoriation, and crusting, mainly on the flexural surfaces of the elbow and knee. In infants it is known as infantile eczema.

D013817 Thermography Imaging the temperatures in a material, or in the body or an organ. Imaging is based on self-emanating infrared radiation (HEAT WAVES), or on changes in properties of the material or tissue that vary with temperature, such as ELASTICITY; MAGNETIC FIELD; or LUMINESCENCE.
