Controversies in in rheumatology and autoimmunity: Is CORA meeting a good educational tool to increase the scientific knowledge?

: Rheumatology and Autoimmunity are closely related fields and are among the most exciting areas in Medicine. Many conditions once regarded as mysterious and incurable are better understood and managed nowadays. Part of the great interest in these subjects derives from the fact that many controversial issues have arisen due to the rapid progression of knowledge, which means they are debatable. Over the years, the Controversies in Rheumatology and Autoimmunity (CORA) meetings promoted critical discussions not as an end but as a tool to increase the scientific knowledge of Rheumatologists and Clinical Immunologists. Beyond pursuing knowledge, being critical means questioning our inveterate beliefs and evaluating new conjectures and hypotheses. Thus, the approach to the debates in Medicine should be done with an open mind and free from all prejudices. Freedom of thought and speech are the fundamental values of our University, as exemplified by the motto "Universa Universis Patavine Libertas" which means "Padua freedom is universal for everyone". Patavine libertas initially referred to freedom from political and religious power but also freedom in research and teaching. For these reasons, Galileo Galilei moved to Padua in 1592, where he spent the most prosperous years of his life before being accused of heresy by the catholic church. We aim for the CORA congress to be an open-minded forum where active participation and exchange of ideas are promoted without prejudice. This special Issue of Autoimmunity Reviews is devoted to some controversies debated during the 7th CORA conference held in Turin, Italy, on March 16-18, 2023. Here we will discuss controversial entities, the use of old and new drugs, and insights into the classification, assessment of disease activity, and management of rheumatic diseases.
