The work has not already been published and has not been submitted simultaneously to any other journal. A short title for use as running head. Abstracts of Case Reports need not be structured. Italian authors must also send an Italian version of the abstract. When essential, they are numbered consecutively and typed at the foot of the appropriate page.
Tables require a heading and figures a legend, also prepared on a separate sheet.
Due to technical reasons, figures with a screen background should not be submitted. On the back of each illustration, indicate its number, the author's name, and 'top' with a soft pencil. Color illustrations are reproduced at the author's expense. The list of references should include only those publications which are cited in the text. The surnames of the authors followed by initials should be given.
