We review the exact solutions of several transcendental equations, obtainedby Siewert and his co-workers, in the '70s. Some of them are expressed in termsof the generalized Lambert functions, recently studied by Mez\"o, Baricz andMugnaini. For some others, precise analytical approximations are obtained. Intwo cases, the asymptotic form of Siewert's solutions are written as Wrightomega functions.
