Teaching pharmacotherapy to students of medicine is concerned with knowledge and understanding, skills and attitudes. These elements can be communicated by using a problem-oriented decision-making process. Learning the logical steps from problem to diagnosis, treatment and result and the feedback to the diagnosis, improves the future capacity of adequately solving the individual patient's problems.
Postponement of menses is widely practised by women using oral contraceptives. One-hundred volunteers, consisting of three groups of women, each group using a different extensively used contraceptive regimen, were tested and compared. The test period consisted mainly of a double (monophasics) or extended (triphasics) pill cycle without a tablet-free interval. Based on daily records of vaginal bleedings as well as on the results of a questionnaire, it could be concluded that postponement of the withdrawal bleeding for twenty extra days was generally effective; the occurrence of the bleedings was related to the duration of postponement of menses and to the contraceptive regimen that was used. However, the introduction of a seven-week cycle pill is not yet a promising alternative since the majority of the volunteers preferred the inconvenience of a monthly withdrawal bleeding.
