Procida Update of Psoriatic Disease

Presented here are the Proceedings of the “Procida Update of Psoriatic Disease,” a conference held at the Orphans’ Conservatory of Terra Murata on the island of Procida in the Gulf of Naples, May 22–24, 2008; and following on a similar conference in Naples in December 2006, which was published in 2007 as a supplement to Reumatismo 1. The Procida conference reported here focused primarily on basic science, imaging, and the clinical and therapeutic aspects of psoriatic disease, thus closely mirroring the 2006 conference plan. Moreover, this supplement provides a further update on imaging, presented at another conference on this theme held in Naples in 2007. The important advances that have emerged since 2006 form a major part of the presentations.

Underpinning the present conference, and like the 2006 meeting, was use of “psoriatic disease,” a term introduced in a Journal editorial2, and which has served to delineate a new approach to understanding the etiology, manifestations, and therapeutic implications of the skin and joint manifestations of psoriasis. This approach has also provided a much needed additional collaboration between rheumatologists and dermatologists. Further, valuable liaisons have been generated between these specialists and workers in related disciplines of imaging, molecular biology, and therapeutics, among others, to throw further light on this fascinating and ever challenging disease complex.

Recent developments in technology and science have enabled remarkably rapid advances in the psoriatic field that were not achieved or envisaged in preceding decades. For example, molecular biology and more sophisticated imaging techniques have allowed new dimensions and facets to be understood, with particular emphasis on the “microcosmic,” compared with the “macrocosmic” level of only a few years ago.

Thus, for example, the importance of the enthesis is now more fully appreciated, and molecular science has thrown further light on therapeutic possibilities for …
