Perhaps you should try some spelling variations:
patient involvement » parental involvement
joint involvement » parent involvement, its involvement, lung involvement
vaiont movement » violent movement, patient movement, joint movement
latter 5 » blatter 5, latter _, matter 5
5 vaiont » _ vaiont, 5 variant
latter y » latter _, latter a, latter i

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: (( latter 5 vaiont movement ) OR ( latter y ((joint involvement) OR (patient involvement)) ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( latter 5 vaiont movement ) or ( latter y ((joint involvement) OR (patient involvement)) ))*".
