Agreement between women's histories of oral contraceptive use and physician records.

The histories of oral contraceptive (OC) use provided by women participating in a study of hepatocellular adenoma (HCA) were compared with records obtained from their physicians. In the HCA study two memory aids were used to assist women in their recall: a calendar of significant events during a woman's lifetime to which she might relate her use of OCs and a book of colour photographs of the 90 OC preparations available up to the time of the study. Using the number of months of a woman's history which could be checked against physician records (mean for all women of 33 months) as the denominator, the highest proportion of concordance was for month-specific duration of OC use (90%) with lower agreement for duration and brand (62%) and duration, brand, and dose (54%). Agreement was better for cases than for controls.

American nurse-midwifery practice in 1976-1977: reflections of 50 years of growth and development.

Nurse-Midwifery was introduced into the United States in 1925 as a means of meeting the maternal and infant care needs of specific rural and urban poor populations. Four studies of US nurse-midwives conducted between 1963 and 1977 describe recent changes and practice in the profession. Approximately 1,000 nurse-midwives employed in the US responded to a questionnaire in late 1976; about 650 of them were in clinical practice. Of those in practice, two-thirds had graduated as nurse-midwives during the prior six years. At least 90 per cent of them provided prenatal care and family planning, and 85 per cent managed labor and delivery and performed postpartum physical examinations. Working collaboratively with physicians, most nurse-midwives manage the care of prenatal patients with some complications. However, relatively few manage multiple gestation or breech deliveries. The 78 per cent of clinical nurse-midwives who provide gynecologic care to non-pregnant women are likely to diagnose gynecologic conditions and treat common problems such as vaginal infections, gonorrhea, condylomata, and lower urinary tract infections. Those who work in small communities are more likely to assume greater responsibility for complicated deliveries and for care of the newborn from birth through infancy.

Intrauterine device termination rates and the menstrual cycle day of insertion.

World-wide clinicians apparently prefer to insert the intrauterine device (IUD) during the bleeding phase of the menstrual cycle. To examine the benefits and risks of inserting IUDs at various times during the menstrual cycle, data on over 9000 women having copper T-200 IUD insertions were analyzed. During the first 2 months after IUD insertion: 1) rates of IUD expulsion are lower the later in the menstrual cycle ;he IUD is inserted; 2) rates of IUD removal for pain and bleeding and rates of accidental pregnancy, are higher the later in the menstrual cycle IUD is inserted, particularly after day 17. The present analysis suggests that the above are probably causal associations. It is estimated that 1000 insertions before day 11 will result in 9 more terminations of IUD use for expulsion, pain and bleeding, and accidental pregnancy than if the insertions are done after day 11. Furthermore, the copper T-200 IUD can be inserted with relative safety on the day it is requested if the woman's history indicates that she is unlikely to be pregnant. There is no justification for a blanket policy of inserting IUDs only during the menses.

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.

Estrogen treatment of teenage girls in the United States: description of the treated population.

It is estimated that each year approximately 20% of all 15- to 19-year-old American girls receive estrogens in the form of a pharmaceutical agent. The proportion of blacks in this age group who receive some form of estrogen therapy is estimated at 36%. The great majority of estrogen use is for the purposes of contraception and, to a lesser extent, suppression of lactation following childbirth. Less than 1% of the girls in this age group receive estrogen for treatment of medical conditions.

The association between oral contraception and hepatocellular adenoma--a preliminary report.

Women with long-term use of oral contraception (OC) are at increased risk of developing a serious, though nonmalignant, liver tumor--hepatocellular ademona (HCA)--according to a case-control study conducted by the Center for Disease Control (CDC) in collaboration with the Armed Forces Institute of Pathology (AFIP). The tumor is sometimes fatal, deaths usually being due to sudden rupture and hemorrhage. This study suggests that, in addition to long-term OC use, a women's age and the hormonal potency of the OC she uses affect her changes of developing HCA. Women 27 years old and older who have used OC with high hormonal potency for 7 or more years are at the greatest risk.
