In a reanalysis of the Million Women Study (MWS), their authors concluded that prolonged use of hormone replacement therapy (HRT) in postmenopausal women increases the risk of ovarian cancer. Although statistically significant their results are clinically irrelevant, since the attributable risk over 5 years is only 4 per 10 000 HRT users, a figure that is not confirmed by other large studies. This risk is much lower than those associated with obesity, lack of physical exercise, smoking and nulliparity, all of which are preventable. Therefore HRT should continue to be prescribed for symptom relief and improvement of quality of life because the benefits far outweigh the very low potential risks.

Magnesium ion inhibits spontaneous and induced contractions of isolated uterine muscle.
Magnesium sulfate, mainly used in obstetrics to treat eclamptic convulsions, is currently questioned as to its clinical tocolytic effect. We aimed to study the relaxant action (if any) of magnesium sulfate on in vitro pregnant and non-pregnant myometrium. ⋯ The present in vitro study suggests a possible benefit of Mg2+ in the inhibition of spontaneous myometrial contractility, but not of uterine-induced hyperactivity.
