British Medical Journal (BMJ)

(Impact factor is 12.8)

Short reports must not exceed 600 words with one table or illustrationand five references.

Clinical Review and Education and Debate articles are mostlycommissioned, but we welcome reports of up to 2000 words onall aspects of medicine and health including sociological aspectsof medicine, polemical pieces, and educational articles. Thesewill be peer reviewed. They should include an unstructured summary ofno more than 150 words.

Editorials are usually commissioned, but we are happy to considerunsolicited editorials of up to 800 words. These will be externallypeer reviewed.

Lessons of the Week are usually case reports or case seriesalerting readers to a potential clinical problem. They shouldbe less than 1200 words long and accompanied by a single sentenceexplaining the lesson. The lesson should be as specific as possibleand aimed at a general audience.

Letters to the editor should be no longer than 400 words witha maximum of five references and one illustration or table. Currently, there is space in the paper journal to publish fewer than one third ofthe letters that we receive. We intend to publish on our website some of the letters that we do not have space for in thepaper journal.

Canadian Medical Association Journal (CMAJ)

(Impact factor is 7.5)

Cases present brief case reports that convey clear, practical lessons. Preference is given to common presentations of important rare conditions, and important unusual presentations of common problems. Articles start with a brief summary (100 words) outlining the case and its relevance to a general audience. The case presentation follows (500 words maximum) as well as a discussion of the underlying condition (1000 words maximum). Generally, up to 5 references are permitted, and visual elements (e.g., tables of the differential diagnosis, clinical features or diagnostic approach) are encouraged. Written consent from patients for publication of their story is a necessity and should accompany submissions. For more information, see

European Journal of Internal Medicine

(Impact factor is 1.0) 

Letters to the editor: A letter to the editor should not exceed 300 words. A maximum of 3 authors may be listed, with only 2 references and no tables or figures.




Journal of American Medical Association

(Impact factor is 25.6): 

Research Letter: Research Letters reporting original research should not exceed 600 words of text and 6 references and may include 1 table or figure. They may have no more than 5 authors; other persons who have contributed to the study may be indicated in an Acknowledgment, with their permission, including their academic degrees, affiliation, contribution to the study, and an indication if compensation was received for their role. Letters must not duplicate other material published or submitted for publication. In general, Research Letters should be divided into the following sections: To the Editor (which serves as an introduction), Methods, Results, and Comment. Research Letters should be double-spaced and a word count should be provided with each letter. They should not include an abstract, but otherwise should follow all of the guidelines in Manuscript Preparation and Submission Requirements. Research Letters considered for publication undergo external peer review.

Brief Report: These manuscripts are short reports of original studies or evaluations or unique, first-time reports of clinical case series. Note: It is very rare for JAMA to publish case reports. A structured abstract is required; for more information, see instructions for preparing structured Abstracts. Recommended length: 1000-1500 words (not including abstract, tables, figures, references, and online-only material) with no more than a total of 3 tables and/or figures.




Journal of General Internal Medicine (JGIM)

(Impact factor is 3.013)

Clinical Vingettes: Clinical vignettes are reports of clinical cases that provide insight into clinical practice and generate hypotheses for innovations in clinical practice, education, and research. They should have an unstructured abstract of 200 words or less and text of up to 2,000 words. The manuscript should include a review of past published relevant cases, a detailed description of the case or vignette, a discussion of why the case or vignette is unique and how it adds to past published literature, and implications for subsequent developments in clinical practice, teaching, or research. The first or senior author of the clinical vignette must be a current SGIM member at the time of submission.

Journal of Internal Medicine

(Impact factor is 0.8)





Journal of Postgraduate Medicine

(Impact factor is 1.5) 

Case reports: New, interesting and rare cases can be reported. They should be unique, describing a great diagnostic or therapeutic challenge and providing a learning point for the readers. Cases with clinical significance or implications will be given priority. These communications could be of up to 1000 words (excluding Abstract and references) and should have the following headings: Abstract (unstructured), Key-words, Introduction, Case report, Discussion, Reference, Tables and Legends in that order. The manuscript could be of up to 1000 words (excluding references and abstract) and could be supported with up to 10 references. Case Reports could be authored by up to four authors. 




Journal of the Royal Society of Medicine

(Impact factor is 0.7)

Case Reports: 800 words, 1 table or figure, abstract 100 words, 5 references



Look for "Authors'" in the left column at:



(Impact factor is 28.6) 

Case Reports. Case reports are intended to inform, entertain, and inspire. Present a diagnostic conundrum, and explain how you solved it. Tell us about the presentation, history, examination, investigations, management, and outcome. In your discussion, educate the reader. Case reports should tell readers about a condition or presentation that they might encounter—so novelty, rarity, and overspecialisation are not what we are looking for. Aim at the generalist: the family doctor, junior psychiatrist, surgeon in training, or the well informed medical student. Use no more than 600 words and 5 references. Explanatory and graphic pictures (up to a maximum of two) can be helpful. Consent for publication in print and electronically must be obtained from the patient or, if this is not possible, the next of kin. See Patients’ consent and permission to publish.

Clinical Pictures. We will consider clear and interesting Clinical Pictures submitted with a descriptive paragraph of 150 words. Authors must obtain signed informed consent from the patient (See Patients’ consent and permission to publish).




Mayo Clinic Proceedings

(Impact factor is 4.8)

Case Reports. Case Reports should be approximately 800 to 1800 words (up to 7 typed, double-spaced pages). Case reports must include a nonstructured abstract. The number of references, tables, and figures should be appropriate for the overall length of the paper. In general, no more than 2 tables or 2 figures are necessary. To better select the highest quality case reports, the editorial board of Mayo Clinic Proceedings has revised and codified our policies for case report review and the standards for acceptance. Manuscripts of the “case report and review of the literature” genre will not be accepted. Other case reports must first demonstrate relevance to the interest of the Mayo Clinic Proceedings readership and importance of the message before they are undergo further review. Publication priority will be given to case reports that identify: A first-of-its-kind, unexpected, or unusual observation of a disease process that is relevant to a meaningful number of patients, such as: a new disease or syndrome a previously unknown or important manifestation of a common disease a new understanding of the pathophysiology of a common disease; a new or first observation of an important side effect of a commonly used drug; or a new therapeutic activity of a new treatment, including drug and non-drug therapies. A small fraction of manuscripts rejected for publication as case reports, but offering some incremental advances in knowledge, may, if appropriately novel, be given priority for conversion to a letter to the editor.

New England Journal of Medicine (NEJM)

(Impact factor is 52.6) 

Brief Reports usually describe one to three patients or a single family. The text is limited to 2000 words, a maximum of 3 tables and figures (total), and up to 25 references. They begin with a brief summary of no more than 100 words.

Clinical Problem-Solving manuscripts consider the step-by-step process of clinical decision making. Information about a patient is presented to an expert clinician or clinicians in stages (indicated by boldface type in the manuscript) to simulate the way such information emerges in clinical practice. The clinician responds (in regular type) as new information is presented, sharing his or her reasoning with the reader. The text should not exceed 2500 words, and there should be no more than 15 references. The use of clinical illustrative materials, such as x-ray films, is encouraged. An example of a Clinical Problem-Solving article can be viewed by clicking here.
