Failure rates among perfect users and during perfect use: a distinction that matters.

To make an informed decision when choosing a contraceptive, women and couples need to know how effective different methods are when used perfectly, where perfect use is defined as following the directions for use. In this article, we show that unbiased estimates of pregnancy rates during perfect use can be guaranteed only if information on consistency and correctness of use is available for each menstrual cycle. The estimated probability of pregnancy during a year of perfect use among the subset of women who always used a method perfectly will be biased upward.

Ectopic gestation following emergency contraceptive pill administration.

Emergency contraceptive pill prescription following rape is common. We report a case of ectopic gestation after emergency contraceptive pill failure and review the literature on this rare complication. A 26-year-old woman with a normal menstrual period 2 weeks before was administered an emergency contraceptive pill 8 hours after a single sexual assault. The assault was her only sexual activity before and after the emergency contraceptive pill use. Forty-six days following the assault, the patient presented with a right ampullary tubal pregnancy of 59 days gestation and underwent emergent surgery for ectopic gestation. To prevent a delay in the diagnosis of ectopic pregnancy, we recommend that providers and the package insert advise women, that ectopic gestation can occur with emergency contraceptive pill failure.

Use of the Retinoid Pregnancy Prevention Program in Canada: patterns of contraception use in women treated with isotretinoin and etretinate.

We sought to describe demographic characteristics of and pattern of contraception use by Canadian women prescribed synthetic retinoids who voluntarily contacted the Motherisk Program in Toronto and to describe the degree of use of the Pregnancy Prevention Program (PPP) for retinoids. Prospectively gathered intake data from isotretinoin-exposed women was statistically compared to that from matched controls selected from our database. Intake data is qualitatively reported for etretinate-exposed women. We included women who voluntarily contacted the Motherisk Program from November 1, 1988, to January 30, 1991, for counseling about reproductive risks of isotretinoin or etretinate. Primary outcome parameters were maternal age, race, marital status, socioeconomic status; gravity, parity, previous miscarriages and elective abortions, maternal tobacco and ethanol exposure, contraception use, and use of PPP (educational components used, patient recollection of warnings). The 26 isotretinoin-exposed women were younger than controls (25.2 [SD 6.7] years vs 28.9 [SD 5.1] years, P = 0.03), tended to be adolescent (30.8% vs. 3.8%, P = 0.014) and sought counselling later in gestation (10.1 [SD 8] weeks vs. 6 [SD 4.2] weeks, P = 0.01). Twenty (77%) knew the drug was teratogenic, yet 10 (38.5%) used no contraception, 6 (23.1%) experienced method failure, and 2 (8%) stopped contraception during isotretinoin therapy. In conclusion, although cognizant of the teratogenicity of isotretinoin, more than one-third of the women in this study used no birth control or experienced contraception failure. In this same group, however, compliance with contraception use appeared to increase in those who saw more of the PPP.

Judgment, 25 February 1986.

The plaintiff, despite using contraceptives, became pregnant. She sought social insurance reimbursement for the costs of an abortion, which she had undergone because she did not want to have a child. The Court upheld the decision of a lower court denying reimbursement. It ruled that pregnancy is not an illness, unless the pregnancy presents for the woman a danger to life or health beyond that involved in normal pregnancies. It reasoned that since the pregnancy presented no such danger and the abortion had not been performed in order to protect the life or health of the plaintiff, the costs of the abortion were not eligible for reimbursement through social insurance, which by law could be used only to cover costs related to illness.
