The relationship between infection and arthritis has occupied the attention of everybody throughout the history of investigative rheu matology, no less today than formerlyl. The present issue is a com pilation of essays reflecting some of the facets of this particular diamond and I am especially grateful to authors and publishers alike in the unusual and tragic circumstances which attended its preparation. We were all stunned and saddened by the untimely death of Pro fessor John Calabro which deprived us of a good friend and wise counsellor as well as a much esteemed professional colleague. Prof. Calabro's contribution to medicine was considerable, spanning highly individual, exemplary and caring clinical management, enthusiastic charismatic teaching at all levels and major contributions to research particularly in the field of juvenile arthritis. As with Robert Burns, whose works John knew, "when will we see his like again?". A personal sadness is that I was looking forward to welcoming John and his wife to "Geordieland". There is a strong tradition of the highest level of competitive ballroom dancing here and John was looking forward to visiting us and demonstrating the considerable skills which he and his wife displayed in this arena. To his wife and family we all extend our heartfelt condolences. W. CARSON DICK 1. Atkin, S., Walker, D., Mander, M., Malcolm, A. and Dick, W. Carson. (1988).
