There are different types of scholarly literature, some of which require original research and some that are based on other published work. It is important to have a clear idea about the different types of articles before publishing. Below notes will help you understand the ways in which you can disseminate your work and identify what kind of article would be suitable for your study.

Research Articles

Original Articles are scientific reports of the results of original clinical research. The text is limited to 3000 words, with an abstract, a maximum of 5 tables and 5 figures, and up to 40 references.

Review Articles

Review articles are usually solicited by the editors, but we will consider unsolicited material. All review articles undergo the peer-review and editorial process as original research papers. A review article surveys and summarizes previously published studies, rather than reporting new facts or analysis. Review articles are sometimes also called survey articles or, in news publishing, overview articles.

Case Reports

Case report is a detailed report of the symptoms, signs, diagnosis, treatment, and follow-up of an individual patient. Case reports may contain a demographic profile of the patient, but usually describe an unusual or novel occurrence.

Special Issue Articles

Special issue articles are scientific reports of original research in such areas as economic policy, ethics, law, and health care delivery. The text is limited to 2700 words, with an abstract, a maximum of 8 tables and figures, and up to 40 references.

Brief Reports

Brief reports usually describe one to three patients or a single family. These are similar to original research in that they follow the same rigor, format and guidelines, but are designed for small-scale research or research that is in early stages of development. These may include preliminary studies that utilize a simple research design or a small sample size and that have produced limited pilot data and initial findings that indicate need for further investigation.


Editorial usually provide commentary and analysis concerning an article in the issue of the Journal in which they appear. They may include a figure or table. They are nearly always solicited, although unsolicited editorials may occasionally be considered.


Perspectivearticles are brief, accessible pieces covering a wide variety of timely topics of relevance to health care and medicine. Perspective articles are limited to 1000 to 1200 words and usually include one figure or table.

Special Reports

Special reports are miscellaneous articles of special interest to the medical community. They are limited to 2700 words.

Letters to the Editor

Letters to the editor provide a forum for readers to comment about articles recently published in the Journal, and they are a place to publish concise articles, such as reports of novel cases.


Images are an important part of much of what we do and learn in medicine. This feature is intended to capture the sense of visual discovery and variety that physicians experience.

Conference Proceedings

Conference proceedings are a collection of academic papers published in the context of an academic conference or workshop.
