For human or animal experimental investigations, it is a prerequisite to provide a formal review and approval, or review and waiver, by an appropriate institutional review board or ethics committee, which should be documented in the paper. For investigations undertaken on human subjects, the manner in which the informed consent was obtained from the study participants (i.e., oral or written) should be stated in the Methods section.
Authors are encouraged to obtain patient consent when they use confidential case material. Consent is not necessary in the case of very brief case vignettes which do not contain identifying information or if the case material is disguised sufficiently to prevent identification of the patient.
In obtaining consent, the author(s) should discuss the purpose(s) of publication, the possible risks and benefits to the patient and the patient’s right to withhold or withdraw consent. In the case of a minor patient, consent should be obtained from the parent(s) or guardian(s).
