The Thyon metagranite is located in the frontal part of the Siviez-Mischabel Nappe, in the western Penninic Alps. It is intrusive in a polymetamorphic banded volcanic complex as leucocratic concordant sills with pseudoaplitic rims. A distinct metamorphic schistosity is defined by dark-green Fe-rich biotite. Abundant mesoperthites, chess-board albite and low microcline are presumably related to magmatic stages and/or greenschist-facies metamorphic retrogression. Major, trace element and REE geochemistry, zircon typology, Y and Nb-bearing accessory minerals such as fergusonite and euxenite, all point to a metaluminous to peraluminous alkaline A-type granite. High-precision U-Pb zircon dating yielded a sub-concordant age of 500 +3/-4 Ma. The Thyon metagranite is the third record of a Cambro-Ordovician alkaline magmatic activity in the Alps. As A-type granitic magmatism is common in post-orogenic to anorogenic extensional tectonic regime, the Thyon intrusion could mark the transition between the Cadomian and the Caledonian orogenies.

Atopic dermatitis is the most frequent dermatosis in childhood. Numerous studies underscored the central role of skin barrier alterations in the pathogenesis of the inflammatory skin lesions. The management of atopic dermatitis has to be multidimensional. It combines among others some daily local care and a sporadic topical anti-inflammatory treatment during the acute flare-ups. The objective of this article is to summarize, in light of the recent European guidelines, the general principles of management of atopic dermatitis, for the general practitioner.
