Conflict of interest and informed consent

Conflict of interest
The publisher believes that authors are obligated to declare no competing interests. If there is any, it should be revealed in the title page of the manuscript.
If an author does not report a conflict, and the editors has suspicions that such a conflict exists, the Editor in Chief may ask for clarification. An article may be rejected if doubts arise about its impartiality and scientific value.
The authors should also provide information on the funding of the study, including the names of the sponsors, along with an overview of the role of these sources.

Informed consent
For each study, the authors of the article should obtain all informed consents from patients for the descriptions of their cases in the studies discussed in the article, as well as the consents referred to in Helsinki Declaration as revised in 2013 (https://www.wma.net/policies-post/wma-declaration-of-helsinki-ethical-principles-for-medical-research-involving-human-subjects) and the consents of the relevant bioethics committees. When submitting an article, the author declares in the cover letter that he has obtained such consent from all the subjects.

Anonymity must be ensured for all study participants. Photographs in which the subjects can be identified require their written consent. It is the responsibility of the author to obtain and keep such consent. In addition, all areas of the photograph that allow recognition of the person depicted must be covered.
