Respiratory Medicine Case Reports is an open access, respiratory journal dedicated to publishing case reports. Case reports must be authentic, understandable, educational and clinically interesting to an international audience of respiratory physicians, trainees and researchers in all respiratory subspecialties, as well as clinicians in related fields. All case reports submitted are peer reviewed and if accepted for publication, authors are notified of this decision and requested to pay an Article Processing Fee of £250 (US$400, Euro 308, JP Yen 30,796) per article (exclusive of VAT which will be charged by Elsevier at the relevant local rate). Following payment of this fee, the article is made universally available to all on www.sciencedirect.com. Online Submission of Manuscripts http://ees.elsevier.com/yrmed

Online Submission of Case Report Manuscripts
Submission and peer review of all papers is now conducted entirely online, increasing efficiency for editors, authors, and reviewers, and enhancing publication speed. Authors are guided stepwise through the entire process, and are kept abreast of the progress of their paper at each stage.
The system creates PDF version of the submitted manuscript for peer review, revision and proofing. All correspondence, including the Editor's decision and request for revisions, is conducted by e-mail.
Authors requesting further information on online submission are strongly encouraged to view the system, including a tutorial, at http://ees.elsevier.com/yrmed.
Authors are asked to bear in mind the guideline peer review and publication times available at the Respiratory Medicine journal homepage: click here for Journal News.

Peer Review
Submissions are allocated to a handling editor, typically an Associate Editor. Should the paper be considered suitable for peer review, appropriate reviewers will be recruited. Authors are required to provide the name and full contact details of 2 potential reviewers, though choice of reviewers is at the discretion of the handling editor.
The final decision-making responsibility lies with the handling editor, who reserves the right to reject the paper despite favourable reviews depending on the priorities of the journal.
For full details on the peer review process and current peer review decision times please click here for Journal News.

Cover letter
Corresponding authors must provide a cover letter which includes statements answering the following questions:

• Has the work been seen and approved by all co-authors?
• How is the work clinically relevant, and how does it add to existing research?
• Have papers closely related to the submitted manuscript been published or submitted for publication elsewhere? If so please provide details.

Authorship
All authors should have made substantial contributions to all of the following: (1) the conception and design of the study, or acquisition of data, or analysis and interpretation of data, (2) drafting the article or revising it critically for important intellectual content, (3) final approval of the version to be submitted.

Acknowledgements
All contributors who do not meet the criteria for authorship as defined above should be listed in an acknowledgements section. Examples of those who might be acknowledged include a person who provided purely technical help, writing assistance, or a department chair who provided only general support. Authors should disclose whether they had any writing assistance and identify the entity that paid for this assistance.

Conflict of interest
The potential for conflict of interest exists when an author (or the author's institution), reviewer or editor has financial or personal relationships that may inappropriately influence his or her actions. Editors and reviewers for the journal are responsible for disclosing to the Chief Editor any personal or financial relationship that may bias their work during the peer review process.
Authors are specifically asked to reflect on financial conflicts of interest (such as employment, consultancy, stock ownership, honoraria and paid expert testimony) as well as other forms of conflict of interest, including personal, academic and intellectual issues.
For the conflict of interest statement all authors must disclose any financial and personal relationships with other people or organisations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. The Conflict of Interest Statement is a mandatory submission item: authors are required to submit the statement to proceed with their submission. Conflict of Interest statements will typically be published within the body of the article, and will appear preceding the references section. All sources of funding should be declared as an acknowledgement at the end of the text. Authors should declare the role of study sponsors, if any, in the study design, in the collection, analysis and interpretation of data; in the writing of the manuscript; and in the decision to submit the manuscript for publication. If the study sponsors had no such involvement, the authors should so state.

Elsevier now sends PDF proofs which can be annotated; for this you will need to download Adobe Reader version 7 available free from Adobe. Instructions on how to annotate PDF files will accompany the proofs. The exact system requirements are given at the Adobe site. If you do not wish to use the PDF annotations function, you may list the corrections (including replies to the Query Form) and return to Elsevier in an e-mail. Please list your corrections quoting line number. If, for any reason, this is not possible, then mark the corrections and any other comments (including replies to the Query Form) on a printout of your proof and return by fax, or scan the pages and e-mail, or by post. Please use this proof only for checking the typesetting, editing, completeness and correctness of the text, tables and figures.
