Maximum length of 600 words, up to 1 figure and 1 table, and no more than 6 authors and 10 bibliographical references.

X-rays and other image techniques (up to a maximum of 3) necessary for the illustration of the discussion may be presented. 2) Differential diagnosis written by the discusser of the case: 6 pages maximum. 3.

Letters to the Editor Preference is given to those letters which make reference to works published the previous month and those which offer opinions, observations or experiences whose characteristics enable them to be summed up in a short text. Maximum length of 600 words, 1 figure or 1 table, 10 bibliographical references and 4 authors. The letter shall begin with the following phrase: ''Mr Editor'' and shall continue with a short introduction, description of the material and methods, presentation of results, and discussion, but without separating or heading the different sections.
Clinical Rheumatology in Images Images of any type (ectoscopic, endoscopic, radiological, microbiological, pathological anatomy) which are highly demonstrative and which in themselves contain a didactic message will be published in this section. Those which combine several different aspects of those mentioned will take preference. They must be accompanied by a text of fewer than 300 words, including presentation of the clinical case, diagnosis and progress, brief comment to discuss the findings observed, and a maximum of 10 bibliographical references and 4 authors. Whenever possible, the photograph should include graphic resources (arrows, asterisks).
