Perhaps you should try some spelling variations:
"politica implicado en anestesiologia ;" » "politica ampliada en anestesiologia ;", "politica implicaciones en anestesiologia ;", "politica implicados en anestesiologia ;", "politica implicadas en anestesiologia ;", "politica aplicado en anestesiologia ;"
"practica juridica de anestesiologia ;" » "practica clinica de anestesiologia ;", "practica medica de anestesiologia ;", "practica juridico de anestesiologia ;"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("practica juridica de anestesiologia ;") OR ("politica implicado en anestesiologia ;"))~.
• Removing quotes may allow a broader search: (( practica juridica de anestesiologia ; ) or ( politica implicado en anestesiologia ; ))~.
• Adding a wildcard symbol may retrieve word variants: (("practica juridica de anestesiologia ;") or ("politica implicado en anestesiologia ;"))*.
