Original Articles:

Original Articles are reports on findings from original unpublished research. Preference for publications will be given to high quality original research that make significant contribution to medicine. The articles should not exceed 4000 words, tables/illustrations up to five (5) and references up to 40. Manuscript describing original research should conform to the IMRAD format, more details are given below.

Review Articles:

Review Articles are solicited articles or systematic reviews. MJM solicits review articles from Malaysian experts to provide a clear, up-to-date account of a topic of interest to medical practice in Malaysia or on topics related to their area of expertise. Unsolicited reviews will also be considered, however authors are encourage to submit systematic reviews rather than narrative reviews. Systematic Review are papers that presents exhaustive, critical assessments of the published literature on relevant topics in medicine. Systematic reviews should be prepared in strict compliance with MOOSE or PRISMA guidelines, or other relevant guidelines for systematic reviews.

Short Communications:

Shorts communication are short research articles of important preliminary observations, findings that extends previously published research, data that does not warrant publication as a full paper, small-scale clinical studies, and clinical audits. Short communications should not exceed 1,000 words and shall consist of a Summary and the Main Text. The summary should be limited to 100 words and provided immediately after the title page. The number of figures and tables should be limited to three (3) and the number of references to ten (10).

Continuing Medical Education (CME) Articles:

A CME article is a critical analysis of a topic of current medical interest. The article should include the clinical question or issue and its importance for general medical practice, specialty practice, or public health. Upon acceptance of selected articles, the authors will be requested to provide five multiple-choice questions, each with five true/false responses, based on the article.

Case Reports:

Papers on case reports (one to five cases) must follow these rules: Case reports should not exceed 1,000 words; with only maximum of one (1) table; two (2) photographs; and up to five (5) references. It shall consists of a Summary and the Main Text. The summary should be limited to 100 words and provided immediately after the title page. Having a unique lesson in the diagnosis, pathology or management of the case is more valuable than mere finding of a rare entity. Being able to report the outcome and length of survival of a rare problem is more valuable than merely describing what treatment was rendered at the time of diagnosis.


Commentaries will usually be invited articles that comment on articles published in the same issue of the MJM. However, unsolicited commentaries on issues relevant to medicine in Malaysia are welcomed. They should not exceed 1,200 words. They maybe unstructured but should be concise. When presenting a point of view it should be supported with the relevant references where necessary.

Letters to Editor:

Letters to Editors are responses to items published in MJM or to communicate a very important message that is time sensitive and cannot wait for the full process of peer review. Letters that include statements of statistics, facts, research, or theories should include only up to three (3) references. Letters that are personal attacks on an author will not be considered for publication. Such correspondence must not exceed 450 words.


These are articles written by the editor or editorial team concerning the MJM or about issues relevant to the journal.


The title page should state the brief title of the paper, full name(s) of the author(s) (with the surname or last name bolded), degrees (limited to one degree or diploma), affiliations and corresponding author’s address. All the authors’ affiliations shall be provided after the authors’ names. Indicate the affiliations with a superscript number at the end of the author’s degrees and at the start of the name of the affiliation. If the author is affiliated to more than one (1) institution, a comma should be used to separate the number for the said affiliation.

Do provide preferred abbreviated author names for indexing purpose, e.g. KL Goh (for Goh Khean Lee), MZ Azhar (for Azhar bin Mohd Zain), K Suresh (for Suresh Kumarasamy) or S Harwant (for Harwant Singh). Authors who have previously published should try as much as possible to keep the abbreviation of their name consistent.

Please indicate the corresponding author and provide the affiliation, full postal address and email.

Abstract and Key Words:

A structured abstract is required for Original and Review Articles. It should be limited to 250 words and provided immediately after the title page.

Give references to established methods, including statistical methods; provide references and brief descriptions of methods that have been published but are not well-known; describe new or substantially modified methods, give reasons for using them and evaluate their limitations.
