Before you complain, I've searched the forums, but I still need some clarification.

Are Italian threaded bottom brackets (being right-hand threaded on both sides)
much more likely to work loose, or has this problem (or myth) been rectified
since one-piece BBs became ubiquitous?

Some people suggest using Loctite, but how does this idea "gel" with the suggestion
that you must grease the BB threads to avoid seizing due to corrosion?
Should I grease the start of thread then Loctite the end?

Thanks
