Therapeutic options for the management of abnormal uterine bleeding.

Just as the investigation of abnormal uterine bleeding (AUB) is approached systematically using the two FIGO systems for AUB in the reproductive years, treatment options can be considered similarly. Therapeutic options fall into two categories-medical and surgical-and while medical management is typically regarded as first-line therapy, there are several exceptions defined by the presenting cause or causes, mainly when infertility is a concurrent issue. In the early 1990s, up to 60% of women underwent a hysterectomy for the symptom of heavy menstrual bleeding (HMB), but this figure has decreased.

Structure and magnetism of the triangular lattice material YbBO.

YbBOis a member of the orthoborate family of materials which contains a triangular arrangement of Ybions. Here we study the physical properties of YbBOwith neutron diffraction, inelastic neutron scattering, specific heat, and ac susceptibility measurements. The neutron diffraction measurements confirm that our samples of YbBOcrystallize in the monoclinic space groupC2/c(#15) which contains two crystallographically distinct Ybsites decorating a slightly distorted triangular lattice.
