XII PTA Training Conference is organized by Polish Society of Allergology (PSA) / Polskie Towarzystwo Alergologiczne (PTA) and will be held from Jun 24 - 27, 2020 at Hotel Golebiewski bei Wisła, Wisla, Slaskie, Poland. Meet under the slogan "Allergology in the laboratory, clinic and office", which reflects a wide spectrum of our interests and everyday work. The scientific program will be a continuation of what is most attractive and interesting in the history of allergological meetings in Wisla to date. However, we want to enrich the conference program with unprecedented elements that will raise interest in participating in this event, such as: •  workshop courses, including food allergy, atopic dermatitis, spirometry, specific immunotherapy and urticaria, •  scientific session dedicated to the European Specialization Examination in Allergology (in the form of the most practical and accessible presentation of this initiative for a wide audience), •  and many others, which we will inform about soon. In addition, the scientific program will include, as usual, hot expected by participants interactive sessions, sessions of the PTA Problem Section and current guidelines. We hope that these proposals and the traditionally high level of scientific presentations in already known forms of scientific sessions, hot topics and workshops will create the right climate for talks on contemporary allergy diagnostics and therapy. Additional details will be posted as soon as they are available.
