A collaborative study of the progesterone intrauterine device (Progestasert). The World Health Organization Task Force on Methods for the Regulation of Implantation.

A randomised double blind study of a plain T-shaped IUD and an active T-shaped IUD releasing 65 micrograms/day of progesterone, has been completed in four centres. A study of 1320 progesterone-releasing IUD's in parous women for 9660 women months of use significant to 18 months, gave a pregnancy rate of 1.0 +/- 0.4, expulsion of 4.7 +/- 0.6 and removals for pain and bleeding of 6.0 +/- 0.7. A detailed analysis of the menstrual bleeding patterns in these patients gave details of the number and length of bleeding and spotting episodes, count of bleeding days, and count of spotting episodes and days for four one-hundred-day reference periods. While the plain IUD contributed a significant number of intermenstrual spotting and bleeding days, the progesterone-releasing IUD contributed more spotting days.

IUD compared with oral contraception in nulliparae.

172 nulliparae attending a Swedish family planning clinic were studied. Doctors and midwives with various experiences gave the contraceptive method. Continuation rate at 12 months was 58 per cent for IUD and 86 per cent for OC. The expulsion rate in the IUD group was 11 per cent and in 30 per cent of IUD users the device was removed because of adverse effects. 10 per cent of the IUD group and 5 per cent of the OC group discontinued their method without introducing another one, thereby risking an unwanted pregnancy.

Estrogens + patient package insert = confused patients.

A brief review of the patient package inserts concept and estrogen pharmacology is presented. Then the need for patient education is discussed along with recommendations for a team approach to managing patient anxiety by helping patients understand the estrogen-containing products they are using.

Do anticonvulsants reduce the efficacy of oral contraceptives?

Women in our area with epilepsy who were also taking oral contraceptives were identified. Of 82 patients taking oral contraceptives, 41 had used both anticonvulsants and oral contraceptives for a total of 955 months. Three documented oral contraceptive (pill) failures occurred during this period, whereas the expected number of 0.12 (relative risk, 25; 95% confience interval, 5 to 73). No pill failures were observed in 2,278 months among women with epilepsy who were taking oral contraceptives but who were not taking anticonvulsants at this time. Thus our data support the suggestion that there is an increased rate of pill failure among women taking anticonvulsants. In view of this diminished effectiveness, the advisability of using oral contraceptives rather than one of the other forms of contraception when anticonvulsant medication is being used concurrently may need to be reevaluated.

Epidemiology of hepatocellular adenoma. The role of oral contraceptive use.

A case-control study of hepatocellular adenoma (HCA), a serious though nonmalignant liver tumor, was conducted by the Center for Disease Control and the Armed Forces Institute of Pathology (AFIP). Interviews with 79 women with HCA and with 220 age- and neighborhood-matched controls were completed. Limited information was obtained on nine additional patients who had died. Women with HCA and hemorrhage have a greater risk of morbidity and death than those with other symptoms. Increasing duration of OC use increases the risk of HCA. Use of OCs with high hormonal potency and age over 30 years may further increase a woman's risk of HCA. Long-term users of OCs have an estimated annual incidence of HCA of 3 to 4 per 100,000.
