What are correct pronunciation for these famous physicians last names? Opie; Mirizzi; Nyhus

These last names anyone has to speak aloud at least once in his/her carrier to an audience:

P.Mirizzi was seemingly an Italian emigrant to Argentina. What way should be the best choice to read up, the Italian or Spanish?

As for Dr.E.Opie (the Opie syndrome, the acute pancreatitis due to a stone incarcerated in the Vater's papilla) he might being of varies nations, etc.

Precisely. My question was about 'immigrants' last names pronunciation.

Some speak as 'MEEREEZEE', some do as 'MEEREETSEE' among my Siberian colleagues. I thought, thre may be some biographic papers about the life of that famous surgeon, a founder of the Argentine school of biliary surgery, and inventor of the intraoperational cholangiography.

As Mirizzi inventions should be referred to during my lecture on the gallstone disease surgery, I ought to name him somehow, and it is very desirable to name him properly.

Thank you very much for 'Opie'!
