Studies on patients or volunteers required ethics committee approval and informed consent, which should be documented in your paper.

If you wish to include images of patients or case details in an Elsevier publication, you will need to adhere to the following requirements:

In order to comply with data protection and privacy rules, each individual who appears in any video, recording, photograph or case report must be made aware in advance of the fact that such photographs are being taken or such video, recording or report is being made and of all of the purposes for which you wish to use them and that individual (or next of kin in the case of children) must give his/her explicit written consent. If such consent is made subject to any conditions (for example, adopting measures to prevent personal identification of the person concerned), Elsevier must be made aware of all such conditions. Written consents must be provided to Elsevier on request.

Particular care should be taken where children are concerned, where a patient's head or face appears or if any reference is made to a patient's name or other personal details.
