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.

Dear Madam Thorley,

Thank you so much! It is so specific matter that is very difficult to find out anywhere.

There is large and influencing Italian diaspora in Argentina, but did Paolo Mirizzi, son or grandson of immigrants, use the original Italian pronunciation in the Spanish-speaking country?

And Opie, was he a Frenchman indeed?

Sincerely,

Andrey Borodach
