Perhaps you should try some spelling variations:
"intensive / critical laser medicine" » "intensive / critical layer medicine", "intensive / critical layers medicine", "intensive / critical cases medicine", "intensive / critical based medicine", "intensive / critical cancer medicine", "intensive / critical disaster medicine"
"intensive / critical case medicine" » "intensive / critical based medicine", "intensive / critical carte medicine", "intensive / critical false medicine"

Try widening your search to All Fields.

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: (((("intensive / critical case medicine") OR ("intensive / critical laser medicine"))) OR ("intensive / critical care medicine")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"intensive / critical case medicine\") OR (\"intensive / critical laser medicine\"))) or (\"intensive / critical care medicine\"))".
• Removing quotes may allow a broader search: (((( intensive / critical case medicine ) OR ( intensive / critical laser medicine ))) or ( intensive / critical care medicine )).
• Adding a wildcard symbol may retrieve word variants: (((("intensive / critical case medicine") OR ("intensive / critical laser medicine"))) or ("intensive / critical care medicine"))*.
