ABSTRACT
The high disease burden in psoriasis and psoriatic arthritis by the loss of healthy years attributable to disability and the loss of years of life caused by premature death justify the interdisciplinary efforts to join forces for the benefit of affected patients. The initial meeting in 2006 had been a great success that was supposed to be continued. For the second time IFPA, the International Federation of Psoriasis Organisations, has organized a world conference on psoriasis and psoriatic arthritis in Stockholm, Sweden, 24th to 28th June 2009. In a joint effort by dermatologists and rheumatologists, these issues were translated into a scientific programme. Promoting interdisciplinary exchange, the disease-defined rather than discipline-specific approach of the second world psoriasis conference dealing with psoriasis revealed that the borders between medical specialities like dermatology and rheumatology or internal medicine not as fixed as traditionally believed.
