INFORMATION FOR AUTHORS Scientific Papers, Brief Scientific Reports, Case Reports The American Journal of Clinical Pathology is devoted to prompt publication of original studies and observations in clinical and anatomic pathology. Original papers relating to laboratory use, management, and information science will be given consideration. An article is received with the understanding that it is submitted solely to the American Journal of Clinical Pathology and that no substantial portion of it is being submitted elsewhere. A manuscript based primarily on data published previously is not acceptable. Send the original typewritten manuscript and a photocopy with two sets of illustrations to: Myrton F. Beeler, M.D., Editor American Journal of Clinical Pathology Box No. 13 Louisiana State University Medical Center 1901 Perdido Street New Orleans, Louisiana 70112 (504) 566-1487 Transmittal letter. Send with the manuscript a covering letter which states that 1) all authors have read and approve the final manuscript; 2) (if applicable) the authors will assume the cost of reproducing color illustrations; 3) when individuals (who have contributed significantly to the study) are acknowledged by name, their permission has been obtained to do so. Also, in conformance with the Copyright Revision Act of 1976, include the following statement, which has been signed by all authors (except federal employees): "In consideration of the American Journal of Clinical Pathology's taking action in reviewing and editing this submission, the author(s) undersigned hereby transfers, assigns or otherwise conveys all copyright ownership to the American Society of Clinical Pathologists in the event that such work is published in the American Journal of Clinical Pathology". Type manuscripts double-spaced throughout, with one-inch margins, on bond paper, 8V2 X 11 inches. Begin a new page for each section (i.e., title page, abstract, text, references, tables, legends, and acknowledgments), numbering pages consecutively. Title page. Include on the title page: 1) a concise title; 2) first name, middle initial, last name of each author plus his highest degree; 3) institutional affiliation of each author; 4) name and address of author to whom reprint requests should be addressed; 5) acknowledgment of source(s) of support; 6) a brief title (40 characters total, including spaces); 7) disclaimers, if any. Abstract and key words. The abstract, not exceeding 150 words, should state the study's purposes, procedures, and significant findings, with emphasis on new observations. Include 3 to 10 key words below the abstract. Text. The Introduction should include only that portion of the literature which is pertinent to the objectives of the study. Clearly state the purpose and rationale of the study being reported. Materials and Methods. Present material in such detail that the work can be duplicated. Reference established methods and describe only new or modified methods. Describe results concisely and in a logical sequence. Tables and figures should be consistent with the text and not be repetitious. Restrict the Discussion to the new and significant aspects of the study and draw conclusions based only on reported data, linking them to the objectives. Lengthy discussion of the subject cannot be permitted because of space limitations. Make Case Reports brief, limited to not more than four printed Journal pages (about twelve double-spaced manuscript pages). Nomenclature. Use Dorland's Medical Dictionary and Webster's International Dictionary as standard references. Use the nomenclature of bacteria given in the 8th Edition of Bergey's Manual of Determinative Bacteriology. Identify all drugs and chemicals used by their generic names, followed, in parentheses, by the chemical formula if the structure is not well known. Proprietary names of drugs may be added in parentheses following the generic names. Units. Express quantitative measurements in the conventional metric units. Follow by SI units, in parentheses, in accordance with the proposal of the National Committee of Clinical Laboratory Standards (NCCLS) Position Paper PPC-11, 1979. Clin Chem 25:657-658, 1979. pH, gas pressure measurements (p02 and pC0 2 ), and osmolality should be reported in conventional units only. Express enzyme activity in International Units per liter (U/L). Base all SI concentration units on a volume of one liter and express amounts in moles, using factors given by Lehmann, HP, Am J Clin Pathol 65:2-20, 1976, except when definitive molecular masses have not been established (e.g.. proteins and mixtures). In describing reagent preparation, give weights and volumes in metric units as at present. Abbreviations. Use standard abbreviations whenever possible (see Council for Biology Editors Style Manual, Council for Biology Editors, 4th Edition, Arlington, VA, 1978). The full term for which the abbreviation stands, followed by the abbreviation in parenthesis, should precede the first use of the abbreviation in the text, except for standard units of measurement. Human and animal experimentation. When reporting results of experimental investigations on human subjects, include a statement that the procedures followed were in accord with the ethical standards established by the institution in which the experiments were performed or are in accord with the Helsinki Declaration of 1975 (Encyclopedia ofBioethics. Vol 4, Warren T. Reich, Editor-in-Chief. Georgetown University, The Free Press, Division of Macmillan Publishing, New York, 1978, pp 1769-1773). Experimental investigations on animals must include a statement indicating that the institution's or the National Research Council's guide for the care and use of laboratory animals was followed. References. References should include only articles cited in the text. They must be arranged and numbered consecutively in alphabetical order. References cited only in the tables or legends to figures should be numbered according to the sequence in which the table or illustration appears in the text. When there are six or fewer authors, list all authors (last name followed by initials). When there are seven or more authors, list only the first three and add el al. Follow this by the full title of the article in lower case (except where a capital is required), the journal title abbreviated according to Index Medicus, the year, the volume number, and inclusive pages. Illustrations. Cite each figure in the text in consecutive order. All illustrations should be submitted as sharp, glossy, black and white, unmounted photographic prints. Photomicrographs should be submitted in a size to fit the Journal columns, 3'A X <9 in. (single column) or 7 X <9 in. (full page). Other sizes will be trimmed prior to publication. Lettering should be of professional quality (not free hand) and legible when reduced for publication. Type illustration titles and explanations on a separate page. Indicate the number of the figure and authors) by writing lightly in pencil or pasting a label on the top-back of illustrations. State the stain and magnification used, in the legend. When photographs of persons are used, the subjects must not be identifiable unless written permission has been obtained. If a figure has been reproduced, acknowledge the original source. Color photographs are reproduced only at the author's expense. Tables. Cite tables in the text in consecutive order. Type each table double-spaced on separate pages. Each column should contain a short heading. Place explanatory material (with nonstandard abbreviations, if not explained in the text) in footnotes to the table. Do not use internal horizontal and vertical lines. Footnotes. Limit use of footnotes. Use symbols in the following order *, t, t, §, ", I **, ftDisposition of manuscript. Receipt of manuscripts will be acknowledged and a decision regarding disposition made as soon as possible. Accepted manuscripts are subject to editorial revision and are not returned. Responsible author will receive galley proof which must be reviewed and returned to the Publisher within 48 hours. An order form for reprints accompanies the galley proof. Letters to the Editor. Only communications referring to an article recently published in the Journal are eligible for acceptance as Letters to the Editor. One month is allowed for the original author's reply, after which the letters) will usually be published within two months. However, for such rapid publication we cannot provide authors with galley proofs or reprints. Letters to the Editor containing figures or complicated tables will go through the usual process. Publication in that case takes about six months. In many instances, such letters are more appropriately submitted as a Brief Scientific Report.
