Preservation of ovarian function, reproductive ability and emotional attitudes in patients with malignant ovarian tumors.

OBJECTIVES: Although cancer is predominantly a disease of aging, an increasing number of women survive malignancies before or during their reproductive years, which may interfere with their fertility potential. Although a variety of studies have tried to document the impact of conservative treatment aimed at preserving ovarian function and reproductive ability, little information has been available regarding survivors' attitudes, emotions, and choices to have children. The aim of this study is to evaluate the reproductive history, experiences, attitudes, and emotions with regard to having children in conservatively treated patients with Stage I epithelial ovarian cancer, any stage LMP tumors, malignant ovarian germ cell tumors (MOGCTs) and Stage I sex cord-stromal tumors (SCSTs). STUDY DESIGN: Between 1986 and 2000, a total of 75 patients with primary malignant ovarian tumors underwent conservative treatment. Out of 75 patients in the study, 14 women (19%) presented Stage I epithelial ovarian cancer, 23 (31%) LMP tumors, 33 (43%) MOGCTs, and five (7%) SCSTs. Information was obtained from medical records and from a questionnaire mailed to all patients who were at least 15 years old at the time of the diagnosis (68 subjects). Median time of follow-up was 102 months (35-192 months). There were four (5.2%) clinical recurrences within 35 months. Only 20 patients (49%) had tried to conceive after the completion of their treatment; of these, 15 women (75%) succeeded and delivered 19 healthy children. Seventy percent (32/41) of the respondents claimed that their disease did not have any impact on their desire to have children. Whereas 51% (21/41) fear that their ovarian disease could have damaged their reproductive potential, 76% (31/41) are not concerned about the effects of the treatment they received on offspring. The impact of the disease on the patients' attitudes toward life was reported as positive. CONCLUSION: The results from our study, in agreement with the data from the literature, confirm that management of Stage I (grade 1, grade 2) epithelial ovarian cancer, any stage LMP tumors, MOGCTs and Stage I SCSTs with fertility-sparing surgery is a safe, practicable treatment option. Though preliminary, this survey provides insight into the attitudes and experiences of young women ovarian cancer survivors regarding fertility.

Buserelin acetate versus expectant management in the treatment of infertility associated with minimal or mild endometriosis: a randomized clinical trial.

OBJECTIVE: We performed a randomized clinical trial to evaluate the efficacy of intranasal 400 micrograms buserelin three times daily for 6 months versus expectant management in the treatment of infertile women with pelvic endometriosis stage I or II of the revised American Fertility Society classification. STUDY DESIGN: Seventy-one consecutive patients (mean age 32 years) were studied at the First Department of Obstetrics and Gynecology, University of Milan, and the Department of Obstetrics and Gynecology, Ospedali Riuniti, Bergamo, between February 1988 and June 1989. Thirty-five women were randomly allocated to buserelin treatment and 36 to expectant management. The baseline distribution of subjects for age, disease stage, and reproductive history was similar in the two groups. All patients were followed regularly; median follow-up was 17 months in the buserelin group and 18 months in the women given expectant management. If pregnancy did not occur within 12 months of randomization, cycles were monitored by ultrasonography and hormone measurements, and when abnormalities were detected clomiphene citrate and human chorionic gonadotropin were administered. RESULTS: A total of 17 pregnancies were observed both in the buserelin-treated patients and in the expectant management group. The 1- and 2-year actuarial overall pregnancy rates were similar in the two groups, 30% and 61% in the former and 37% and 61% in the latter group, respectively. Spontaneous abortion occurred in five of the 17 pregnancies in the women treated with buserelin and in one of the 17 in those managed expectantly; this difference was, however, not statistically significant (chi 1(2) adjusted for disease stage and use of clomiphene citrate and human chorionic gonadotropin treatment = 3.01, p = 0.08). No fetal death or stillbirth was observed. CONCLUSIONS: Our findings suggest that treatment with gonadotropin-releasing hormone agonists is unlikely to have a marked influence on the reproductive outcome of infertile women with minimal or mild endometriosis.

Reproductive and gynecologic surgical experience in diethylstilbestrol-exposed daughters.

Information on reproductive history, gynecologic operations, and examinations was analyzed for 338 diethylstilbestrol (DES)-exposed and 298 unexposed women whose mothers participated in an evaluation of DES use in pregnancy 28 years ago. A history of infrequent menses (less often than every 36 days) was reported more commonly by the exposed women (32%) than by the unexposed women (15%) and the mean duration of menstrual flow was also less. A greater number of exposed women than unexposed women experienced primary infertility (53 versus 19). The reasons for these differences are not currently known. Comparison of the outcomes of first pregnancies showed a higher proportion of premature births, spontaneous abortions, and ectopic pregnancies in the exposed women (P less than 0.001). The difference in the occurrence of ectopic pregnancies was statistically significant (8 versus 0; P less than 0.005). An adverse pregnancy outcome was more likely in DES-exposed women with cervicovaginal ridges. However, when the outcome of all pregnancies were considered, 81% of the exposed women had at least one living child. More exposed women than unexposed women had gynecologic surgical procedures, which may, in part, be due to the increased medical surveillance of the exposed group. The spectrum of diseases at operation in both groups was similar. Adnexal masses and pelvic inflammatory disease were more commonly reported among the exposed women while the occurrence of endometriosis in both groups was similar. For the exposed women who had been examined at the Chicago Lying-In Hospital over a 4-year period, epithelial changes in the vagina had disappeared in 32% and cervicovaginal ridges had disappeared in 57%.

Scleroderma epidemiology.

Evidence from multiple sources indicates that SSc does not occur randomly in the population; there are particular groups who are at greater risk. The overall incidence rate of SSc in the adult population of the United States is approximately 20 per million per year; this rate has increased from 1944 to 1973, but has been relatively stable since that time. The prevalence of SSc in the United States also seems to be stable over the past two decades with a prevalence estimate for adults of 240 per million. Recent population studies suggest that SSc occurs more frequently in the United States than in continental Europe, the United Kingdom, and in some areas in Asia. Overall survival has improved over the past few decades; mean survival is approximately 12 years from diagnosis. Renal disease accounts for some of the early mortality, but pulmonary disease has emerged as a major cause of death. Cardiac disease is also correlated with a poorer prognosis. Gastrointestinal involvement contributes to morbidity and, indirectly, to mortality, but the magnitude of this contribution is difficult to assess. Women are affected more frequently than men but the factors that are responsible for this are not apparent. Studies of reproductive history have provided conflicting data; some studies suggested that the number of pregnancies may influence later disease expression, whereas other studies found no correlation. Racial factors seem to play a role in disease susceptibility, as well as disease expression. Age-specific incidence rates are higher in black women than in white women; the greatest difference occurs in the young to middle adult age group (less than 54 years of age). Diffuse disease also seems to occur more commonly in the black population than in the white. Age at onset of diffuse disease is younger, on average, than the age at onset of limited disease; age-adjusted survival is worse in black women than in white women because of their predilection for diffuse disease. Reports of geographic clustering are intriguing; the reported clusters in London and Italy have not resulted in the identification of potential causal factors. The Choctaw Native American cluster suggests that genetic factors that have not been identified may play an important role. Familial clustering of SSc has been demonstrated in the United States and in Australia, which provides additional evidence of a genetic component. It is likely that there is a strong interplay among genetic factors, hormonal or reproductive-related events, and an external trigger that must interact to result in clinical disease.

Personal and environmental characteristics related to epithelial ovarian cancer. I. Reproductive and menstrual events and oral contraceptive use.

In two case-control studies conducted in the six-county San Francisco Bay Area, 111 women diagnosed with epithelial ovarian carcinoma in 1974-1977 and 188 women diagnosed in 1983-1985 were interviewed concerning their menstrual, sexual, and reproductive histories. For comparison, interviews were conducted with 752 control women admitted to the same hospitals within six months of the cases; for cases diagnosed in the later period, interviews were also conducted with an additional 259 population-based controls selected by random digit dialing. Controls were matched to cases by age and race. Qualitative and quantitative findings were similar for the two studies. In the combined data, cases were more likely than their matched controls to have been nulliparous, to have undergone menarche at an early age, and to have refrained from using oral contraceptives. Menopause occurred slightly later for cases than for controls, but the differences were not statistically significant. Neither age at first term pregnancy (20 or more weeks gestation) nor number of term pregnancies was predictive of ovarian cancer risk. The protection afforded by oral contraceptive use was independent of parity, and it increased with increasing duration of use. There were no trends in risk with time since last oral contraceptive use or with time since first use, after adjustment for duration of use. These observations suggest that oral contraceptive use decreases risk for ovarian cancer, rather than merely indicates fertility, which may itself decrease risk of developing the disease. The authors combined reproductive characteristics and oral contraceptive use to estimate a woman's total duration of ovulation, which was positively associated with ovarian cancer risk (p less than 0.001 for trend). These observations support the concept that the greater the duration of ovulation or accompanying endocrinologic phenomena, the greater a woman's risk for ovarian cancer.

Pregnancy and obstetrical outcomes in pseudoxanthoma elasticum.

BACKGROUND: Pseudoxanthoma elasticum (PXE) is a genetic multisystem disorder characterized by calcified dystrophic elastic fibres in skin, retina and arteries. Much of the earlier literature on pregnancy in PXE contained reports of severe complications, leading some healthcare providers to advise women with PXE against becoming pregnant and some women with PXE to avoid pregnancy. OBJECTIVES: To evaluate the obstetrical outcomes and the incidence of pregnancy complications in women with PXE and to determine if pregnancy is associated with an adverse effect on the course of the disease. METHODS: Women with PXE (n = 407) answered detailed questionnaires regarding reproductive history and pregnancy as well as the course of their disease. The frequency of reported pregnancy outcomes and complications was determined. Severity indices for the major clinical manifestations of PXE were developed and correlated with gravidity of affected women aged 40 years or over. RESULTS: Among the 306 respondents with PXE who had ever been pregnant, there were 795 pregnancies. Of these, 83% ended in live births and 1% in stillbirth. The median birth weight was within the normal range and the incidence of low birth weight for gestation was low. Hypertension occurred in 10% of pregnancies, gastric bleeding and retinal complications in < 1%, and 12% of pregnancies were associated with worsening of skin manifestations. There was no effect of gravidity and clinical severity on cutaneous (P = 0.07), ocular (P = 0.59) or cardiac (P = 0.42) manifestations of PXE in women aged 40+ years, nor did ever having been pregnant adversely affect these clinical severity indices. Of the 101 women who had never been pregnant, 17% made the decision because they were advised against becoming pregnant by a healthcare professional and 11% did not become pregnant because they feared an adverse outcome either in their pregnancy or disease. CONCLUSIONS: PXE is not associated with markedly increased fetal loss or adverse reproductive outcomes. The incidence of gastric bleeding, although probably higher than in the unaffected population, is much lower than previously reported, and retinal complications are uncommon. Although a few pregnancies were associated with worsening of skin manifestations, there was no correlation of either gravidity or ever having been pregnant with ultimate severity of skin, ocular or cardiovascular manifestations. There is no basis for advising women with PXE to avoid becoming pregnant, and most pregnancies in PXE are uncomplicated.

An exploratory analysis of the effect of pesticide exposure on the risk of spontaneous abortion in an Ontario farm population.

The toxicity of pesticides on human reproduction is largely unknown--particularly how mixtures of pesticide products might affect fetal toxicity. The Ontario Farm Family Health Study collected data by questionnaire on the identity and timing of pesticide use on the farm, lifestyle factors, and a complete reproductive history from the farm operator and eligible couples living on the farm. A total of 2,110 women provided information on 3,936 pregnancies, including 395 spontaneous abortions. To explore critical windows of exposure and target sites for toxicity, we examined exposures separately for preconception (3 months before and up to month of conception) and postconception (first trimester) windows and for early (< 12 weeks) and late (12-19 weeks) spontaneous abortions. We observed moderate increases in risk of early abortions for preconception exposures to phenoxy acetic acid herbicides [odds ratio (OR) = 1.5; 95% confidence interval (CI), 1.1-2.1], triazines (OR = 1.4; 95% CI, 1.0-2.0), and any herbicide (OR = 1.4; 95% CI, 1.1-1.9). For late abortions, preconception exposure to glyphosate (OR = 1.7; 95% CI, 1.0-2.9), thiocarbamates (OR = 1.8; 95% CI, 1.1-3.0), and the miscellaneous class of pesticides (OR = 1.5; 95% CI, 1.0-2.4) was associated with elevated risks. Postconception exposures were generally associated with late spontaneous abortions. Older maternal age (> 34 years of age) was the strongest risk factor for spontaneous abortions, and we observed several interactions between pesticides in the older age group using Classification and Regression Tree analysis. This study shows that timing of exposure and restricting analyses to more homogeneous endpoints are important in characterizing the reproductive toxicity of pesticides.

The natural history of homocystinuria due to cystathionine beta-synthase deficiency.

An international questionnaire survey has been conducted to define better the natural history of homocystinuria due to cystathionine beta-synthase deficiency and permit evaluation of treatment. Data were compiled for 629 patients. Among patients not discovered by newborn screening, B6-responsive individuals on the average have significantly better mental capabilities (mean IQ, 79) than do B6-nonresponsive individuals (mean IQ, 57). Time-to-event curves are presented for the other major clinical abnormalities produced by this disease. Each occurred at significantly lower rates in untreated B6-responsive than in untreated B6-nonresponsive patients, as shown by the following examples: (1) dislocation of optic lenses (at age 10, chances of dislocation: 55% and 82%, respectively); (2) initial clinically detected thromboembolic events (at age 15, chances of having had such an event: 12% and 27%, respectively); (3) radiologic detection of spinal osteoporosis (at age 15, chances of such osteoporosis having been detected: 36% and 64%, respectively); and (4) mortality (at age 30, chances of not surviving: 4% and 23%, respectively). Methionine restriction initiated neonatally prevented mental retardation, retarded the rate of lens dislocation, and may have reduced the incidence of seizures. Pyridoxine treatment of late-detected B6-responsive patients retarded the rate of occurrence of initial thromboembolic events. Following 586 surgical procedures, 25 postoperative thromboembolic complications occurred, six of which were fatal. Reproductive histories were reported predominantly for B6-responsive patients. Living offspring of either men or women patients had few abnormalities. The evidence is inconclusive whether untreated maternal cystathionine beta-synthase deficiency leads to excessive fetal loss. Only 13% of patients detected in screening programs of newborns and classified as to B6-responsiveness were B6-responsive, compared to 47% among late-detected patients. Current screening programs that identify neonatal hypermethioninemia may be preferentially failing to detect B6-responsive patients.

An assessment of fertility in boron-exposed Turkish subpopulations.

Relationships between elevated boron intake and fertility were sought by comparing reproduction in the residents of two Turkish villages with high levels of boron in their drinking water (one with 8.5 to 29 mg B/L and the other with 2.05 to 2.5 mg B/L), with three nearby villages with more typical low boron levels (0.03 to 0.40 mg B/L). The two high boron villages were designated as Region I, and the three villages with low boron in the drinking water were designated Region II. In addition to exposure to elevated boron in drinking water, 28.3% of the probands in Region I were employed in borate mining or processing, whereas in Region II, 11.7% were so employed. An observational study was carried out in which the authors compared the reproductive history of families living in Region I with families living in Region II by identifying married adults (referred to as probands) who were able to provide information about their and their spouses' family pedigrees covering three generations. Probands were identified by home visits and, if ever married, accepted for ascertainment. Evidence of fertility was birth of a living child, and data were obtained about the fertility of the proband generation, their parents' and also their childrens' generations. In high-boron villages (Region I), 159 three-generation kindreds containing 1068 families were ascertained and, in low-boron villages (Region II), 154 three-generation kindreds containing 610 families were ascertained. In Region 1, 96% of marriages produced at least one child, with primary infertility estimated at 2.34% compared with 96% and 2.62%, respectively, for Region II. There was no significant difference in fertility either between Region I and Region II or between the villages within the Regions. The fertility figures are not different from similar measures of fertility in other parts of Turkey. In Region I, the gender ratio (M:F) of offspring was 0.89, whereas in the Region II villages the gender ratio was 1.04 (NS, chi2 = 1.335, P > 0.05). It is concluded that at the elevated boron drinking water levels studied, a boron-related effect on reproduction was not found.

Female infertility after ileal pouch-anal anastomosis for ulcerative colitis.

PURPOSE: Although ulcerative colitis commonly affects young females, the impact of ulcerative colitis and its treatment on female fertility have not been well studied. The purpose of this survey was to examine the impact of ulcerative colitis and ileal pouch-anal anastomosis on female reproductive ability. METHODS: Demographic, reproductive history, and disease history information were obtained via a questionnaire mailed to females who had pelvic pouch surgery or nonoperative management for ulcerative colitis. Based on age at diagnosis, age at surgery, and marital status, 153 females who had pelvic pouch surgery and 60 females who had nonoperative management for ulcerative colitis were identified for inclusion. Patients were asked if they attempted to become pregnant, when relative to their diagnosis or surgery, and if they were successful. Married or cohabiting females aged 18 to 44 years who failed to become pregnant during 12 months of unprotected intercourse were defined as infertile. RESULTS: The infertility rate was significantly higher in females who had pelvic pouch surgery compared with females managed nonoperatively (59/153 (38.1 percent) vs. 8/60 (13.3 percent), respectively; P < 0.001). There was no difference in female fertility after diagnosis with ulcerative colitis compared with before diagnosis (odds ratio, 0.68; P = 0.23). In contrast, there was a 98 percent reduction in fertility after pelvic pouch surgery compared with before surgery (odds ratio, 0.021; P < 0.0001). By logistic regression, increasing age was the only factor associated with failure to become pregnant after surgery (odds ratio, 1.136 per additional year of age; P = 0.027). CONCLUSIONS: Females with ulcerative colitis who are managed nonoperatively have normal fertility, which suggests that ulcerative colitis and medical therapy do not decrease female reproductive ability. After pelvic pouch surgery for ulcerative colitis, female fertility is significantly decreased and this problem should be discussed routinely with patients considering this procedure.

Sexual selection and mating advantages in the giant sperm species, Drosophila bifurca.

Mate choice may be exercised by either sex; however, females are generally choosier than males because they invest more in their gametes. Female choice is often based on direct benefits, such as better reproductive output, whereas male choice appears to be based on differences in female fecundity. However, when gamete production is limited, sexual selection theories predict that mate choice will be decisive for reproductive success in both sexes. Here, we investigate how mating advantage is achieved in Drosophila bifurca, a giant sperm species in which both sexes produce only a few gametes. Our initial expectations were as follows: (1) females would discriminate against sperm-depleted males to avoid fertility cost; and (2) males would discriminate against inseminated females to reduce sperm competition and increase the assurance of paternity of individual gametes. Differences in courtship behaviors were analyzed with regard to the sexual maturity, which is reached after 22 days in males at 21 degrees C, and the reproductive history of both sexes (inseminated versus virgin for females, and sperm-depleted versus sperm-loaded for males). Our results show that: (1) sexual immaturity precludes mating in both sexes; (2) virgin females do not discriminate between sperm-loaded and sperm-depleted males, and (3) males mate preferentially with virgin females, because inseminated females fend off the male, which tended to bring male courtship to an end. Female remating was limited, but increased significantly when the first male was sperm-depleted. Contrary to our initial expectations, these findings suggest that male sperm depletion does not affect female mating preference, whereas the success of male courtship is driven by female behavior. The possibility that female remating was only promoted in response to low sperm transfer is discussed in relation to the gametic system of this species.

Fertility behavior and reproductive outcomes among young Guatemalan adults.

Fertility rates have declined in many developing countries and this has implications for health and development of subsequent generations. Guatemala has the highest fertility rates in Central America. Reproductive histories were obtained by interview in 2002-04, in a cohort of 779 women and 647 men who had participated as young children in a nutrition supplementation trial in Guatemala conducted between 1969 and 1977. Most women (77%) and men (79%) are currently married. Among the 700 women and 524 men reporting at least one birth, mean age at first birth was 20.7 +/- 3.8 years and 23.1 +/- 3.9 years respectively. Knowledge (> 80%) and use (approximately 70%) of modern contraceptive methods is fairly high; knowledge increases with parental socioeconomic status (SES) as measured in 1975. Younger respondents have experienced fewer pregnancies and live births compared with older respondents; age-specific fertility rates between 20 and 24 years were 294, 249, 236, and 261 births per 1,000 women, respectively, for women born from 1962-65, 1966-69, 1969-73, and 1974-77. Women in the top tertile of parental SES have had significantly fewer pregnancies (3.3) compared with those in the middle (3.7) and lower (3.8) tertiles. Migrants to Guatemala City reported greater knowledge of contraceptive methods, fewer pregnancies and living children, higher age at first birth, and more pregnancy and newborn complications as compared with cohort members who remained in the original villages (p < .05 for each comparison). Fertility rates, especially between 20 and 24 years, have declined over time. Differences in reproductive behaviors by parental SES and current residence suggest the role of social transitions in determining family formation in Guatemala.

Evaluation of reproductive outcomes in women inadvertently exposed to hexachlorobenzene in southeastern Turkey in the 1950s.

In southeastern Turkey during the period of 1955-57, women were accidentally exposed to the fungicide hexachlorobenzene (HCB) after eating contaminated seed grain and developed porphyria cutanea tarda (PCT). While HCB has been shown to be a potent oocyte toxicant in primates and has been identified as an ovarian follicular fluid contaminant in women, its effect on human reproduction is poorly understood. This study was undertaken to evaluate the effects of HCB on women with a known high dose exposure. A retrospective controlled cohort comparison study of three groups was conducted. Group 1, those with confirmed PCT; Group 2, controls for the region and Group 3, controls for the country of Turkey, were followed-up after approximately 40 years (n=42/group). Blood samples were taken for analysis of serum HCB, estradiol, follicle-stimulating hormone (FSH) and inhibin. Frequency of HCB detection was greatest in Group 3, while number of cases with HCB values exceeding 1 ng/mL was significantly greater in Groups 1 and 2. There were no differences in the other biochemical measures. Interviews were completed for each patient regarding reproductive history (number of pregnancies, live births, spontaneous abortions, still births and sex of live babies). Multiple comparisons of the three groups, based on Fisher's test found the groups were inhomogeneous. When serum HCB was analyzed using correlated response logistic regression, there was a strong relationship between serum HCB levels and risk for spontaneous abortion but not sex ratio of children. The following findings were made. HCB is detectable and ubiquitous in serum samples from women in the country of Turkey with identified and unidentified exposure events. Spontaneous abortion risk is not restricted to women with identifiable exposure to HCB but to a surrogate marker of exposure (serum HCB sample). The risk of spontaneous abortion with HCB exposure requires further investigation.

Female sterilization in Latin America: cross-national perspectives.

Fertility levels have dropped substantially in Latin America in recent decades, fuelled by increased contraceptive use and notably a method mix skewed towards female sterilization. This study examined choice of female sterilization in four Latin American countries: Brazil, Colombia, the Dominican Republic and Peru. Data were drawn from national Demographic and Health Surveys conducted in 1995--1996. Discrete-time hazard models were used on the five-year calendar modules of women's reproductive histories to consider the effects of a number of sociodemographic and contextual determinants as they pertained to status at the moment of the event. The results revealed that the likelihood of a woman's having undergone contraceptive sterilization was increasing over time in Brazil and Peru, suggesting that the potential for future growth of this method remains strong. A consistent pattern of increased probability of sterilization with higher education was seen across all countries, seemingly dispelling certain controversial claims that the procedure may have been disproportionately performed on the poor. At the same time, the multilevel analytical approach pointed to significant cluster-level random effects, suggesting that there were additional unmeasured contextual influences on women's propensity to choose sterilization.

The perimenopause: a critical time in a woman's life.

The interval from the initiation of declining estrogen levels to final ovarian failure usually encompasses many years. The age of onset and duration of this perimenopausal time can vary greatly. While many patients may have minimal to no symptoms as estrogen levels first begin to decrease, most patients will eventually develop symptoms and sequelae as they approach ovarian failure. The consequences of this decline in ovarian function are numerous, and include vasomotor symptoms, declining bone mass, urogenital changes, infertility, irregular uterine bleeding, and psychosexual dysfunction. The women of today entering the perimenopausal period are unique because of their vast numbers, a consequence of the aging of the "baby boomers." Their reproductive history is also different from that of their ancestors in that many have chosen to delay childbearing into their thirties and even forties, and many have elected not to have children. Because of the unique characteristics of this extremely large population of women that are approaching or currently in the perimenopausal period, it is vital that healthcare providers fully understand the variability, consequences, and treatment modalities of this time of declining ovarian function. Risk factors for such common health problems as osteoporosis, heart disease, and cancers must be assessed and managed appropriately. Screening tests including mammography and cholesterol profiles should be offered along with dietary and exercise recommendations. Low-dose oral contraceptive pills and hormone replacement therapy are often effective in preventing and treating many of the common problems encountered during the perimenopausal period.

A prospective cohort study of oral contraceptives and cancer of the endometrium.

A prospective cohort study of approximately 97 300 women was conducted in eastern Massachusetts. Information on use of oral contraceptives, and on gynaecological and reproductive histories was sought through mailed questionnaires, while newly diagnosed cases of cancer of the endometrium were identified from records of 34 area hospitals. Oral contraceptive (OC) use was associated with some increase in endometrial cancer rates (standardized rate ratio = 1.4; 95% confidence interval = 0.9-2.4), although the risk did not vary consistently by length of use, years since first use, or age at initial use. Although some subgroups of users had rates of disease higher than among nonusers, there was little to suggest a consistent association between OC use and incidence of endometrial cancer.

Swedish maternal mortality in the 19th century by different definitions: previous stillbirths but not multiparity risk factor for maternal death.

BACKGROUND: The high maternal mortality levels in today's developing countries were also found throughout the history of currently affluent countries. The parish information system in Sweden offers unique possibilities for research in historical cohorts. Furthermore, vital events surveillance systems are scarce in today's developing countries. METHODS: This cohort study covers 42,387 mothers who gave birth to 150,932 infants during the 19th century in the Skellefteå and Sundsvall areas. Among these women, 1,237 were dead within one year after delivery. The analysis of the cause of these deaths was done according to the various ICD definitions. Parity five and above was defined as grand multiparity. RESULTS: Maternal mortality ratios, deaths per 100,000 live births were as follows: 256.4 (direct obstetric deaths), 320.7 (direct and indirect obstetric deaths), 489.2 (pregnancy-related deaths), 347.8 (late maternal deaths) and 837.0 (maternal deaths and late maternal deaths). In this study, 59% of all maternal deaths occur within the first 42 days of delivery, two thirds of them having direct and indirect obstetric causes. Of the late maternal deaths, the bulk were infectious or other indirect deaths, mirroring more general female mortality and the pre-existent endemic situation of tuberculosis and other infectious diseases. The combination of previous stillbirth and infant death represented the highest risk ratios, RR 2.77-3.62, while grand multiparity was not associated with increased risk. Urbanized and industrialized areas tended to have higher maternal mortality. CONCLUSIONS: In conclusion, this study shows that the mother's reproductive history was the most important risk factor measured for all definitions of maternal death. Grand multiparity did not increase the risk of maternal death. Maternal mortality ratio varied threefold in the study population, depending on the definition used. The high mortality ratios found in this study, only declining by the end of the century, should be interpreted as a general condition of the society since no significant differences could be perceived regarding social class, while unmarried women were more at risk.

Reproductive performance of women with unicornuate uterus.

The reproductive history of 19 women with a diagnosis of unicornuate uterus confirmed by laparoscopy or laparotomy is analyzed. The patients were followed for 2 to 10 years. One patient had a cavitary communicating rudimentary horn, four a cavitary noncommunicating rudimentary horn, seven a noncavitary rudimentary horn, and seven no rudimentary horn. Six of the patients presented with primary infertility. The other 13 women had a total of 29 pregnancies, 1 (3.4%) in a rudimentary horn determining rupture; abortions occurred in 17 (58.6%), premature labor in 3 (10.3%), and term births in 8 (27.6%), with a live birth rate of 38%. Of the 11 births, 6 (54.5%) were breech presentations, and 9 (81.8%) were cesarean sections. In five cases the rudimentary horn was removed, with associated salpingooophorectomy in three patients. Cervical cerclage was not performed in any of the patients.
