Approval of research protocols by the Ethics Committee following International Agreements (World Medical Association Declaration of Helsinki “Ethical Principles for Medical Research Involving Human Subjects,” amended in October 2013) is required for experimental, clinical, and drug studies and for some case reports. 
If required, ethics committee reports or an equivalent official document will be asked from the authors. 
For manuscripts concerning experimental research on humans, a statement should be included that shows that written informed consent of patients and volunteers was obtained following a detailed explanation of the procedures that they may undergo. 
For studies carried out on animals, the measures taken to prevent pain and suffering of the animals should be stated clearly. Information on patient consent, the name of the ethics committee, and the ethics committee approval number should also be stated in the Materials and Methods section of the manuscript. It is the authors’ responsibility to protect the patients’ anonymity carefully. For photographs that may reveal the identity of the patients, signed releases of the patient or of their legal representative should be enclosed.
