Retrospective ethics approval
If a study has not been granted ethics committee approval prior to commencing, retrospective ethics approval usually cannot be obtained and it may not be possible to consider the manuscript for peer review. The decision on whether to proceed to peer review in such cases is at the Editor's discretion.

New clinical tools and procedures
Authors reporting the use of a new procedure or tool in a clinical setting, for example as a technical advance or case report, must give a clear justification in the manuscript for why the new procedure or tool was deemed more appropriate than usual clinical practice to meet the patient’s clinical need. Such justification is not required if the new procedure is already approved for clinical use at the authors’ institution.
