Interesting, Demo, al those short articles about POIS suddenly appearing in web magazines.... it looks like they read each others content and import some topics.
POIS is trending, too bad they talk about desensitization, when even Waldinger himself have abandoned it, and that they talk about POIS as just an "allergy" rather than a complex immune disorder, again like Waldinger do now.
Maybe the will catch on, when Dr Waldinger will come out with his latest study, and clarifies his view, explaining that POIS is an immune disorder in his view, now, like he explained in his April 2016 review article.
