IN THIS EDITION WE CELEBRATE the 100th issue of the Saúde em Debate Journal (RSD). During these 38 years of existence and resistance, RSD has been one of the most important vehicles for the dissemination of debate concerning the Brazilian health reform, the Unified Health System' (SUS) paths and diversions, and the construction of critical thinking in the Brazilian and Latin American health field. The Journal's historical role in the public health field is undeniable. In RSD, sanitarians found space to express their opinions and to disseminate the results of their studies and research, while professionals found references to political and care practices.

For RSD to reach such a level as academic and political vehicle, many efforts have been undertaken. We will not try to name names, because we certainly would not be fair to all those who have devoted themselves directly or indirectly to the Journal during this long period beginning in 1976. We want to thank the authors, advisors, publishers, reviewers and proofreaders who work or worked for the Journal, mostly free and voluntarily, believing in the core role of a journal as a means of dissemination of scientific knowledge produced in the fields of health research.

Currently, RSD is part of LILACS database (Literatura Latino-americana e do Caribe em Ciências da Saúde), HISA (História da Saúde Pública na América Latina e Caribe), LATINDEX (Sistema regional de Información en Línea para Revistas Científicas de America Latina, el Caribe, España y Portugal), SUMÁRIOS (Sumários de Revistas Brasileiras), PERIÓDICA (Índice de Revistas Latino-americano em Ciências), and, in 2012, it joined SciELO (Scientific Electronic Library Online). As of this issue, also, the reader will notice a redesign of the magazine, which has made it more legible, modern and dynamic.

We stress that, contrary to a large number of Brazilian and foreign scientific journals, RSD has resisted the adoption of any publication policies allowing charging for publication of articles. Thus, we believe to have broadened authors' access and contributed to democratize the dissemination of socially relevant scientific knowledge which addresses dilemmas and challenges of national and international health. In order to accomplish that, however, we need to rely on the support of institutions committed to national health. In recent years, Fiocruz has been an invaluable partner, for which we are very thankful.

Finally, we believe that the confrontation of ideas coming from different streams of thought is central to the debate in any field of knowledge. In this sense, RSD is opened to theoretical and methodological contributions of different sciences as an aid to understand the complex reality that characterizes the health field, without, however, abandoning the ideas we have always advocated of health as right and of public and universal health systems. These assumptions also guide the Journal's editorial policy.
