Opis

The meeting which took place in Rome on November 19th and 20th of 1982 is easily the best meeting on hepatic coma that I have ever attended, and I have attended many. It was an exceedingly we- planned meeting with prolonged opportunity for discussion, and there was genuine interplay and exchange of ideas (not the usual picture of a rushed meeting with investigators presenting their own point of view and talking past each other without a meaningful ex change) which took place in Rome. My co-editors and I hope that the published transcript, which of course can only reflect what transpired in Rome on those two days, does justice to a very intellectually exciting and gratifying ex change of ideas.
