The topics discussed include the role proton-neutron pairing on the binding energies of pf-shell nuclei and his influence on backbending rotors; coulomb energy differences and their relationship with alignment. Proton-neutron correlations are found responsible for the characteristic features of the isotopic shifts in calcium, the parabolic dependence on A and the prominent odd-even staggering.Invited talk at "High Spin Physics 2001", see http://www.fuw.edu.pl/~hs2001/, to be published in Acta Physica Polonica BNuclear Theorytext
