Abstract
The Editor welcomes all letters whether they are short case reports, preliminary reports of research, discussion or comments on papers published in the journal. Letters commenting on a paper may be sent to the authors of that paper so that their reply may appear in the same issue.
There is no rigid limit to length but in general the shorter the letter the better the chance of publication. Authors should follow the same guidelines given for the preparation and submission of articles on the inside back covers of each issue, especially that regarding tables or illustrations. Letters should be signed by all authors.
