    Total abdominal and vaginal hysterectomy has been the standard treatment for intractable and unmanageable menorrhagia for many years. However, in the last few years, hysteroscopic treatment of menorrhagia through surgical resection and/or ablation of the endometrial cavity has gained success. Over 625000 hysterectomies are performed each year in the USA alone. More than 30 % are done for menorrhagia as a primary diagnosis. Three times more hysterectomies are performed using the abdominal route than the vaginal approach. Morbidity is higher using the abdominal route alone. Complications of abdominal and vaginal hysterectomies will be briefly discussed. Menorrhagia caused by submucous fibroids can be treated hysteroscopically. A review of methods, complications, advantages and long-term follow up will be presented. Laparoscopically-assisted vaginal hysterectomy (LAVH) is the latest surgical option offered for menorrhagia. The advent of a hysteroscopic approach to the treatment of menorrhagia and careful analysis of the advantages and disadvantages of LAVH will be discussed.

    Abstract We report the first kinetic study of iron oxidation in a mica. Large singly-crystal biotite wafers were heated in air to various temperatures and for various times. Room temperature 57Fe Mössbauer spectroscopy was used to quantify the resulting Fe2+ and Fe3+ amounts. A simple activation model is consistent with the measurements and gives an activation energy of e b = 2.36 eV and an attempt frequency of f 0 = 2.9×107 Hz. We are lead to propose that, iron oxidation and ordinary dehydroxylation have the same rate limiting step: local dissociation of an OH group as OH−→O2-+H+. In oxidation this is followed by Fe2+ +H+→Fe3+H whereas in dehydroxylation it is followed by OH− +H+→H2O.
