Randomized Controlled Trial Comparative Study Clinical TrialVaginal bleeding disturbances associated with the discontinuation of long-acting injectable contraceptives. From the World Health Organization Special Programme for Research, Development, and Research Training in Human Reproduction; Task Force on Long-acting Systemic Agents for the Regulation of Fertility.
A randomized comparative trial of 832 women receiving norethisterone oenanthate (NET-OEN) and 846 women receiving depot medroxyprogesterone acetate (DMPA) injections at 12 week intervals was conducted in 10 centers. The pregnancy rate with NET-OEN was significantly higher than with DMPA. ⋯ Bleeding for more than 30 days during an injection interval and complete amenorrhoea for a whole injection interval were jointly associated with 43.7% of all terminations among NET-OEN users and 64.5% of all terminations among DMPA users. In future efforts to improve the acceptability of long-acting injectable contraceptives, more attention should be given to the control of prolonged amenorrhoea and prolonged bleeding.

Randomized Controlled Trial Clinical TrialEffect of bromocriptine on the premenstrual syndrome. A double-blind clinical trial.
Twenty-one patients suffering from the premenstrual syndrome were each studied during three menstrual cycles. After a control cycle, bromocriptine and placebo were given during the luteal phase of the cycle in a random double-blind cross-over manner, each patient serving as her own control. ⋯ Serum progesterone and oestradiol-17-beta were within normal ranges, and did not change during treatment. Medication considerably improved all the premenstrual symptoms, but mastodynia was the only one where bromocriptine was significantly better than the placebo.
