title: [Sarcoidosis: A Descriptive Approach to the Global Research Network and Recent Scientific Developments].
abstract: OBJECTIVE
  Sarcoidosis continues to be an underestimated disease that can cause severe morbidity and mortality in individuals. There has, however, been an increasing awareness of this disease as shown by the increasing number of publications since the 1990  s. The large number of available publications makes it challenging for a single scientist to provide an overview of the topic. To quantify the global research activity in this field, a scientometric investigation was conducted.
  
  
  METHODS
  The total number of publications on sarcoidosis was determined in the Web of Science to obtain their bibliometric data for the period 1900-2008. According to the NewQIS-protocol, different visualisation techniques and scientometric methods were applied.
  
  
  RESULTS
  A total of 14,190 published items were evaluated. The U.S. takes a leading position in terms of the overall number of publications and collaborations. Prolific institutions and authors are of U.S. origin. Only a relatively small number of international co-operations were identified. The most intensive network is between the "University of Colorado" and the "National Jewish Medical Research Center". "Semenzato, G" has the highest citation rate of all authors. The most productive co-operative author is "du Bois, RM".
  
  
  CONCLUSIONS
  The scientific interest in the topic sarcoidosis is growing steadily. The influence of international co-operation on scientific progress in this area is of increasing importance.
