Nævus anémique généralisé acquis

Abstract

We are reporting a case of generalized nevus anemicus in an adult, which was not associated with phacomatosis or pheochromocytoma. The pharmacological investigation of the vasomotricity showed permanent vasoconstriction in the anemic areas. The cutaneous levels of catecholamines were seven times as high in the anemic areas as in the sound areas. We have investigated a possible increase in the number of APUD by a histochemical method (Grimelius’s stain). This possible increase might have accounted for a local hypersecretion of catecholamines. Our investigation was negative. No etiological mechanism can be suggested.

Sartre’s Postcartesian Ontology: On Negation and Existence

“…Dupré has remarked that, only recently, a small number of thinkers, including Maurice Blondel, Paul Ricoeur and Karl Jaspers, have "begun to rethink the relation between freedom and causality in noncausal terms." 45 Perhaps in anticipating this recent effort to renew the question of transcendence, Sartre no longer defines freedom as a mode of conduct that follows a causal principle but invites us to imagine how it begins in a situation that does not define it in advance: "Freedom is total and infinite, which does not mean that it has no limits but that it never encounters them." 46 In other words, the limits to freedom are those that it imposes on itself and that derive solely from facticity, the surrounding world and the techniques through which we communicate with others.…”
