to organize 20 symposia in a row if the topics lack actual relevance and the speakers are not of excellent reputation. Dr. Smit Sibinga has proven to have a keen eye for selecting interesting themes and eminent speakers. Although a lot of different topics have been dealt with in the past 20 years, which each attracted the attention of a different group in the field of blood transfusion, it is not surprising that after a tradition of 20 years several speakers but also a lot of attendees are not for the first time in Groningen to participate in this event. It gives the symposium a unique atmosphere of intimacy. It is not hard to admit that most of the newer developments in transfusion medicine take place outside the Netherlands.
