Saint nearly enrols helper from the East, for this kind of treatment (10)
I believe the answer is:
paediatric
'saint nearly enrols helper from the east for this kind of treatment' is the definition.
The definition suggests an adjective which matches the answer.
This is all the clue.
Can you help me to learn more?
(Other definitions for paediatric that I've seen before include "A patricide (anag.)" , "dealing with children" , "complaints concerning him?" , "Treating children" .)
