Types of Articles

Original research articles (3,000~ 4,000 words not including tables, and figures)

These papers are designed to test certain research hypotheses, or to systematically carry out empirical observations in a clinical setting. Articles should begin with an introduction (or background), followed by Materials and Methods, Results, Discussion, and conclusion. A statement of protocol approval number by the institutional animal care and use committee (IACUC) or equivalent must be included in the Materials and Methods section of the paper.

Case Reports (1,200~1,500 words)

Case reports should have no more than five authors. The abstract should be no longer than 200 words and should include statements of the problem, clinical manifestations, methods of treatment, and outcome. The approval number of the IRB document must be reported in the Materials and Methods section of the manuscript. The article should include statements of the problem, patient history, methods, diagnosis, treatment, results, and any other information pertinent to the case(s). All other sections should follow the format for original research articles. The number of references should not exceed 25.

Brief Reports (1,200~ 1,500 words)

This category is for small but interesting findings, or for imaginative hypotheses with strong plausibility. Papers dealing with issues under debate or introducing certain vital clinical skills are also included in this category.

Review Articles (4,000~ 5,000 words)

These summaries should be written for a general medical audience. Topics belonging to this category include state-of-art medical knowledge and in-depth discussions on vital research questions.

Letters to the editor (500~ 600 words)

We invite succinct responses to published papers, as well as research letters with original data.
