Query: Threefold extremal curve germs with one non-Gorenstein point   An extremal curve germ is the analytic germ of a threefold with terminal
singularities along a reduced complete curve admitting a contraction whose
fibers have dimension at most one. The aim of the present paper is to review
the results concerning those contractions whose central fiber is irreducible
and contains only one non-Gorenstein point.
