Instructions for Authors

Categories of Articles?

Original Articles should report original research relevant to clinical surgery. Each manuscript should be accompanied with a structured abstract divided into aims, material and methods (which should include design, setting, subjects, methods), results and conclusion in not more than 250 words. Four to five key words to facilitate indexing should be provided along with the abstract. The text should be divided in sections of introduction, methods, results and discussion. Key messages should be provided at the end of the manuscript. The length should be 2500-3500 words with not more than 6 tables and 3 figures.

Review Articles or systematic and critical assessments of literature are also published. The length should be 2000-3000 words (excluding tables, figures, and references).

Case Reports should consist of clinical cases highlighting uncommon conditions or presentations. Single case reports should provide information regarding new or unusual aspects of aetiology, diagnosis or management which adds to the existing knowledge. The text should be up to 1000 words and divided into sections - abstract (50 words), introduction, case report and discussion. Number of tables/figures (black and white photographs only) should be limited to 2 and up to 10 most recent references.

Letters to the Editor commenting upon a recent article in IJOHNS are welcome within 6 months of the article's publication. At the Editorial Boards' discretion, the letter may be sent to the authors and both letter and reply may be published together. Letters may also relate to other topics of interest to paediatric surgeons, and/or useful clinical observations. Letters should be up to 500 words, contain not more than one Figure/Table and 5 most recent references. The text need not be divided into sections.

Authors preparing their manuscript in LaTeX can use the bibtex file spbasic.bst which is included in Springer’s LaTeX macro package.

• All tables are to be numbered using Arabic numerals.
• Tables should always be cited in text in consecutive numerical order.
• For each table, please supply a table caption (title) explaining the components of the table.
• Identify any previously published material by giving the original source in the form of a reference at the end of the table caption.
• Footnotes to tables should be indicated by superscript lower-case letters (or asterisks for significance values and other statistical data) and included beneath the table body.

Electronic Figure Submission

• Supply all figures electronically.
• Indicate what graphics program was used to create the artwork.
• For vector graphics, the preferred format is EPS;
• for halftones, please use TIFF format. MSOffice files are also acceptable.
• Vector graphics containing fonts must have the fonts embedded in the files.
• Name your figure files with "Fig" and the figure number, e.g., Fig1.eps.

Line Art

• Definition: Black and white graphic with no shading.
• Do not use faint lines and/or lettering and check that all lines and lettering within the figures are legible at final size.
• All lines should be at least 0.1 mm (0.3 pt) wide.
• Scanned line drawings and line drawings in bitmap format should have a minimum resolution of 1200 dpi.
• Vector graphics containing fonts must have the fonts embedded in the files.

Halftone Art

• Definition: Photographs, drawings, or paintings with fine shading, etc.
• If any magnification is used in the photographs, indicate this by using scale bars within the figures themselves.
• Halftones should have a minimum resolution of 300 dpi.

Combination Art

Definition:
a combination of halftone and line art, e.g., halftones containing line drawing, extensive lettering, color diagrams, etc.

Combination artwork should have a minimum resolution of 600 dpi.

Color Art

• Color art is free of charge for online publication.

• If black and white will be shown in the print version, make sure that the main information will still be visible. Many colors are not distinguishable from one another when converted to black and white. A simple way to check this is to make a xerographic copy to see if the necessary distinctions between the different colors are still apparent.
• If the figures will be printed in black and white, do not refer to color in the captions.
• Color illustrations should be submitted as RGB (8 bits per channel).

Figure Lettering

• To add lettering, it is best to use Helvetica or Arial (sans serif fonts).
• Keep lettering consistently sized throughout your final-sized artwork, usually about 2–3 mm (8–12 pt).
• Variance of type size within an illustration should be minimal, e.g., do not use 8-pt type on an axis and 20-pt type for the axis label.
• Avoid effects such as shading, outline letters, etc.
• Do not include titles or captions within your illustrations.

Figure Numbering

• All figures are to be numbered using Arabic numerals.
• Figures should always be cited in text in consecutive numerical order.
• Figure parts should be denoted by lowercase letters (a, b, c, etc.).
• If an appendix appears in your article and it contains one or more figures, continue the consecutive numbering of the main text. Do not number the appendix figures,
• "A1, A2, A3, etc." Figures in online appendices (Electronic Supplementary Material) should, however, be numbered separately.

Figure Captions

• Each figure should have a concise caption describing accurately what the figure depicts. Include the captions in the text file of the manuscript, not in the figure file.
• Figure captions begin with the term Fig. in bold type, followed by the figure number, also in bold type.
• No punctuation is to be included after the number, nor is any punctuation to be placed at the end of the caption.
• Identify all elements found in the figure in the figure caption; and use boxes, circles, etc., as coordinate points in graphs.
• Identify previously published material by giving the original source in the form of a reference citation at the end of the figure caption.

Figure Placement and Size

• Figures should be submitted separately from the text, if possible.
• When preparing your figures, size figures to fit in the column width.
• For most journals the figures should be 39 mm, 84 mm, 129 mm, or 174 mm wide and not higher than 234 mm.
• For books and book-sized journals, the figures should be 80 mm or 122 mm wide and not higher than 198 mm.

Permissions

• If you include figures that have already been published elsewhere, you must obtain permission from the copyright owner(s) for both the print and online format. Please be aware that some publishers do not grant electronic rights for free and that Springer will not be able to refund any costs that may have occurred to receive these permissions. In such cases, material from other sources should be used.

Accessibility

• In order to give people of all abilities and disabilities access to the content of your figures, please make sure that
• All figures have descriptive captions (blind users could then use a text-to-speech software or a text-to-Braille hardware)
• Patterns are used instead of or in addition to colors for conveying information (colorblind users would then be able to distinguish the visual elements)
• Any figure lettering has a contrast ratio of at least 4.5:1

Springer accepts electronic multimedia files (animations, movies, audio, etc.) and other supplementary files to be published online along with an article or a book chapter. This feature can add dimension to the author's article, as certain information cannot be printed or is more convenient in electronic form.

Before submitting research datasets as electronic supplementary material, authors should read the journal’s Research data policy. We encourage research data to be archived in data repositories wherever possible.

Submission

• Supply all supplementary material in standard file formats.
• Please include in each file the following information: article title, journal name, author names; affiliation and e-mail address of the corresponding author.
• To accommodate user downloads, please keep in mind that larger-sized files may require very long download times and that some users may experience other problems during downloading.

Audio, Video, and Animations

• Aspect ratio: 16:9 or 4:3
• Maximum file size: 25 GB
• Minimum video duration: 1 sec
• Supported file formats: avi, wmv, mp4, mov, m2p, mp2, mpg, mpeg, flv, mxf, mts, m4v, 3gp

• It is possible to collect multiple files in a .zip or .gz file.

Numbering

• If supplying any supplementary material, the text must make specific mention of the material as a citation, similar to that of figures and tables.
• Refer to the supplementary files as “Online Resource”, e.g., "... as shown in the animation (Online Resource 3)", “... additional data are given in Online Resource 4”.
• Name the files consecutively, e.g. “ESM_3.mpg”, “ESM_4.pdf”.

Captions

• For each supplementary material, please supply a concise caption describing the content of the file.

Processing of supplementary files

• Electronic supplementary material will be published as received from the author without any conversion, editing, or reformatting.

Accessibility

• In order to give people of all abilities and disabilities access to the content of your supplementary files, please make sure that
• The manuscript contains a descriptive caption for each supplementary material
• Video files do not contain anything that flashes more than three times per second (so that users prone to seizures caused by such effects are not put at risk)

This journal is committed to upholding the integrity of the scientific record. As a member of the Committee on Publication Ethics (COPE) the journal will follow the COPE guidelines on how to deal with potential acts of misconduct.

Authors should refrain from misrepresenting research results which could damage the trust in the journal, the professionalism of scientific authorship, and ultimately the entire scientific endeavour. Maintaining integrity of the research and its presentation can be achieved by following the rules of good scientific practice, which include:

• The manuscript has not been submitted to more than one journal for simultaneous consideration.
• The manuscript has not been published previously (partly or in full), unless the new work concerns an expansion of previous work (please provide transparency on the re-use of material to avoid the hint of text-recycling (“self-plagiarism”)).
• A single study is not split up into several parts to increase the quantity of submissions and submitted to various journals or to one journal over time (e.g. “salami-publishing”).
• No data have been fabricated or manipulated (including images) to support your conclusions
• No data, text, or theories by others are presented as if they were the author’s own (“plagiarism”). Proper acknowledgements to other works must be given (this includes material that is closely copied (near verbatim), summarized and/or paraphrased), quotation marks are used for verbatim copying of material, and permissions are secured for material that is copyrighted.
• Important note: the journal may use software to screen for plagiarism.
• Consent to submit has been received explicitly from all co-authors, as well as from the responsible authorities - tacitly or explicitly - at the institute/organization where the work has been carried out, before the work is submitted.
• Authors whose names appear on the submission have contributed sufficiently to the scientific work and therefore share collective responsibility and accountability for the results.
• Authors are strongly advised to ensure the correct author group, corresponding author, and order of authors at submission. Changes of authorship or in the order of authors are not accepted after acceptance of a manuscript.
• Adding and/or deleting authors and/or changing the order of authors at revision stage may be justifiably warranted. A letter must accompany the revised manuscript to explain the reason for the change(s) and the contribution role(s) of the added and/or deleted author(s). Further documentation may be required to support your request.
• Requests for addition or removal of authors as a result of authorship disputes after acceptance are honored after formal notification by the institute or independent body and/or when there is agreement between all authors.
• Upon request authors should be prepared to send relevant documentation or data in order to verify the validity of the results. This could be in the form of raw data, samples, records, etc. Sensitive information in the form of confidential proprietary data is excluded.

If there is a suspicion of misconduct, the journal will carry out an investigation following the COPE guidelines. If, after investigation, the allegation seems to raise valid concerns, the accused author will be contacted and given an opportunity to address the issue. If misconduct has been established beyond reasonable doubt, this may result in the Editor-in-Chief’s implementation of the following measures, including, but not limited to:

• If the article is still under consideration, it may be rejected and returned to the author.
• If the article has already been published online, depending on the nature and severity of the infraction, either an erratum will be placed with the article or in severe cases complete retraction of the article will occur. The reason must be given in the published erratum or retraction note. Please note that retraction means that the paper is maintained on the platform, watermarked "retracted" and explanation for the retraction is provided in a note linked to the watermarked article.
• The author’s institution may be informed.

To ensure objectivity and transparency in research and to ensure that accepted principles of ethical and professional conduct have been followed, authors should include information regarding sources of funding, potential conflicts of interest (financial or non-financial), informed consent if the research involved human participants, and a statement on welfare of animals if the research involved animals.

Authors should include the following statements (if applicable) in a separate section entitled “Compliance with Ethical Standards” when submitting a paper:

• Disclosure of potential conflicts of interest
• Research involving Human Participants and/or Animals
• Informed consent

Please note that standards could vary slightly per journal dependent on their peer review policies (i.e. single or double blind peer review) as well as per journal subject discipline. Before submitting your article check the instructions following this section carefully.

The corresponding author should be prepared to collect documentation of compliance with ethical standards and send if requested during peer review or after publication.

The Editors reserve the right to reject manuscripts that do not comply with the above-mentioned guidelines. The author will be held responsible for false statements or failure to fulfill the above-mentioned guidelines.

Authors must disclose all relationships or interests that could influence or bias the work. Although an author may not feel there are conflicts, disclosure of relationships and interests affords a more transparent process, leading to an accurate and objective assessment of the work. Awareness of real or perceived conflicts of interests is a perspective to which the readers are entitled and is not meant to imply that a financial relationship with an organization that sponsored the research or compensation for consultancy work is inappropriate. Examples of potential conflicts of interests that are directly or indirectly related to the research may include but are not limited to the following:

• Research grants from funding agencies (please give the research funder and the grant number)
• Honoraria for speaking at symposia
• Financial support for attending symposia
• Financial support for educational programs
• Employment or consultation
• Support from a project sponsor
• Position on advisory board or board of directors or other type of management relationships
• Multiple affiliations
• Financial relationships, for example equity ownership or investment interest
• Intellectual property rights (e.g. patents, copyrights and royalties from such rights)
• Holdings of spouse and/or children that may have financial interest in the work

In addition, interests that go beyond financial interests and compensation (non-financial interests) that may be important to readers should be disclosed. These may include but are not limited to personal relationships or competing interests directly or indirectly tied to this research, or professional interests or personal beliefs that may influence your research.

The corresponding author collects the conflict of interest disclosure forms from all authors.

Please note that each author should complete a disclosure form. Examples of forms are

• COI-all authors form
• COI-corresponding author form
• COI-ICMJE modified form
• ICMJE form

The corresponding author will include a summary statement on the title page that is separate from their manuscript, that reflects what is recorded in the potential conflict of interest disclosure form(s).

See below examples of disclosures:

1) Statement of human rights
When reporting studies that involve human participants, authors should include a statement that the studies have been approved by the appropriate institutional and/or national research ethics committee and have been performed in accordance with the ethical standards as laid down in the 1964 Declaration of Helsinki and its later amendments or comparable ethical standards.

If doubt exists whether the research was conducted in accordance with the 1964 Helsinki Declaration or comparable standards, the authors must explain the reasons for their approach, and demonstrate that the independent ethics committee or institutional review board explicitly approved the doubtful aspects of the study.

The following statements should be included in the text before the References section:

Ethical approval: “All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.”

All individuals have individual rights that are not to be infringed. Individual participants in studies have, for example, the right to decide what happens to the (identifiable) personal data gathered, to what they have said during a study or an interview, as well as to any photograph that was taken. Hence it is important that all participants gave their informed consent in writing prior to inclusion in the study. Identifying details (names, dates of birth, identity numbers and other information) of the participants that were studied should not be published in written descriptions, photographs, and genetic profiles unless the information is essential for scientific purposes and the participant (or parent or guardian if the participant is incapable) gave written informed consent for publication. Complete anonymity is difficult to achieve in some cases, and informed consent should be obtained if there is any doubt. For example, masking the eye region in photographs of participants is inadequate protection of anonymity. If identifying characteristics are altered to protect anonymity, such as in genetic profiles, authors should provide assurance that alterations do not distort scientific meaning.

The following statement should be included:

• Informed consent: “Informed consent was obtained from all individual participants included in the study.”
• If identifying information about participants is available in the article, the following statement should be included: “Additional informed consent was obtained from all individual participants for whom identifying information is included in this article.”
