D.P.E.J.

Spanish to English Medical Medical (general)

Could someone advise what D.P.E.J.means? It's on an document (letter) from Mexico with regards to an annual clinical trial report.

This appears in small print at the bottom left of the letter under the title 'Records' and then '​D.G.P (Dirección General de Profesiones [Directorate General of Professions]) (followed by the registry number). D.P.E.J. is also followed by a number (registry number)

All I seem to find through my search is 'Diccionario panhispánico del español jurídico' which doesn't seem right here as it's a dictionary. Is there something I'm missing from this?

Any suggestions much appreciated.
