Perhaps you should try some spelling variations:
"clinical mexicanas en anestesiologia ;" » "clinicas mexicanas en anestesiologia ;", "clinical medicine en anestesiologia ;", "clinical mexicanas de anestesiologia ;", "clinical mexicanos en anestesiologia ;", "clinical mexicano en anestesiologia ;"
"prensa mexicana en anestesiologia ;" » "prensa mexicana de anestesiologia ;", "poesia mexicana en anestesiologia ;", "prensa mexico en anestesiologia ;", "revista mexicana en anestesiologia ;"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"clinical mexicanas en anestesiologia ;\") OR (\"prensa mexicana en anestesiologia ;\"))~".
• Removing quotes may allow a broader search: (( clinical mexicanas en anestesiologia ; ) OR ( prensa mexicana en anestesiologia ; ))~.
• Adding a wildcard symbol may retrieve word variants: (("clinical mexicanas en anestesiologia ;") OR ("prensa mexicana en anestesiologia ;"))*.
