To describe the mortality of female breast cancer in Brazil according to color, in the years 2000 and 2010.
A descriptive study in which demographic data were obtained from the Brazilian Institute of Geography and Statistics (IBGE). The breast cancer death information in Brazil was collected from the Ministry of Health through the Mortality Information System (SIM). The crude mortality rates for female breast cancer were calculated according to color and age group, up to 49 years and ≥50 years. The results obtained were distributed into five geographical regions of the country (North, Northeast, Midwest, South and Southeast).
In Brazil, in women aged 50 or more, the highest crude mortality rates of breast cancer in 2000 were 62.6/100,000, 46.0/100,000 and 29.7/100,000 among yellow, white and black women, respectively. In women under 50 years in 2000, the crude mortality ranged from 2.0/100,000 among indigenous women to 6.8/100,000 among white women. After ten years, in women over 50 years, the crude mortality rate among yellow, white and black women was 21.5, 53.2 and 40.4 per 100,000, respectively. In the country's regions, the highest mortality rates of breast cancer were observed in white and black women from the South and Southeast. In the Northeast, mortality rates in black and brown women doubled in 2010.
Breast cancer mortality rates show ethnic and geographical variations. However, it is not possible to exclude the possibility that large variations have occurred as a result of improvement in the quality of information on mortality in the country.

PURPOSE: To describe the prevalence of maternal mortality at a tertiary care hospital and to assessits preventability. METHODS: This study, through the analysis of maternal deaths that occurred during the period from 1999 to 2010 at a reference in Campinas - Brazil, CAISM/ UNICAMP, discusses some of the factors associated with the main causes of death and some structural problems of structure of the health services. It is a retrospective descriptive study with evaluation of sociodemographic variables and the medical and obstetric history of women, and the causes of death. RESULTS: The majority of maternal deaths occurred due to direct obstetric (45%) and avoidable (36%) causes, in women with preterm gestation, who delivered by cesarean section (56%) and received various management procedures, including blood transfusion, ICU admission and need for laparotomy and/or hysterectomy. The hospital transfer was associated with the predominance of direct obstetric (19 versus 6, p=0.02) and avoidable causes (22 versus 9, p=0.01). CONCLUSIONS: We conclude that, despite current advances in Obstetrics, infections and hypertensive disorders are still the predominant causes of maternal mortality. We observed an increase of clinical-surgical conditions and neoplasms as causes of death among women during pregnancy.

PURPOSE: to compare the blood pressure and oxygen consumption (VO2) responses between pregnant and non-pregnant women, during cycle ergometer exercise on land and in water. METHODS: ten pregnant (27 to 29 weeks of gestation) and ten non-pregnant women were enrolled. Two cardiopulmonary tests were performed on a cycle ergometer (water and land) at the heart rate corresponding to VO2, over a period of 30 minutes each. Exercise measurements consisted of recording blood pressure every five minutes, and heart rate and VO2 every 20 seconds. Two-way ANOVA was used and α=0.05 (SPSS 17.0). RESULTS: there was no difference in cardiovascular responses between pregnant and non-pregnant women during the exercise. The Pregnant Group demonstrated significant differences in systolic (131.6±8.2; 142.6±11.3 mmHg), diastolic (64.8±5.9; 74.5±5.3 mmHg), and mean blood pressure (87.0±4.1; 97.2±5.7 mmHg), during water and land exercise, respectively. The Non-pregnant women Group also had a significantly lower systolic (130.5±8.4; 135.9±8.7 mmHg), diastolic (67.4±5.7; 69.0±10.1 mmHg), and mean blood pressure (88.4±4.8; 91.3±7.8 mmHg) during water exercise compared to the land one. There were no significant differences in VO2 values between water and land exercises or between pregnant and non-pregnant women. After the first five-minute recovery period, both blood pressure and VO2 were similar to pre-exercise values. CONCLUSIONS: for pregnant women with 27 to 29 weeks of gestation, water exercise at the heart rate corresponding to VO2 is physiologically appropriate. These women also present a lower blood pressure response to exercise in water than on land.

PURPOSE: to generate knowledge in order to allow of the determination the factors affecting the high incidence of caesarean section and its relation to sterilization. METHODS: the multicentric study on reproductive health in Brazil, carried out from 1998 to 2000, included the States of Rio Grande do Norte, Minas Gerais, São Paulo, and Rio Grande do Sul. It was characterized as a longitudinal study, where the women, proceeding from public as well as private health services, were interviewed at three moments: at the beginning of pregnancy (until the 22nd week of gestation), at the end of pregnancy (between 30 and 40 days before the probable date of childbirth) and after delivery (between 15 and 45 days after childbirth). The interviewed women complied with the following eligibility criteria: to have 18 to 40 years of age, to live in Natal and plan to deliver the baby in Natal. At the first moment, 433 women were interviewed, 380 at the second moment and 269 at the third moment. The data were submitted to the chi-square test, with the level of significance set at 0.05, just to assure the relation between the variable years of schooling (0 to 8 and 9 or +) and the representative variables for reproductive health. RESULTS: the result disclosed a statistically significant relationship (p<0.05) between the variables: years of schooling, parity, type of service used, social class, job status, and prenatal consultations. It was found that a higher educational level is predominant among those women who searched for private services, coming from higher social classes and large number of prenatal visits. Although without statistical significance, having a for the women coming from this type of service, a higher number of caesarean section5 was observed, probably due to an easy doctor-patient interaction, while the planned caesarean section was frustrated for 43% of those women coming from public health services, as well as the wish to have a tubal ligation at childbirth (57%). CONCLUSIONS: These results show up the great differentials between the private and public services, with a clear favoritism for the private sector, demonstrating clearly that the practical obstetrics in Brazil needs a change and an improvement both for those women with access to the private service, who obtain the accomplishment of the caesarean section without consistent medical indications, and those with access to the public service, who face difficulties in accomplishing this procedure, even with consistent medical indications, in order to provide equality in the reproductive rights of those women.

PURPOSE: to evaluate acceptability, adhesion and experience with the use of female condom (FC) among HIV-infected women. METHODS: prospective descriptive study with 76 HIV-infected women under care at CAISM/UNICAMP and Centro Corsini, both in Campinas. After a screening interview and agreeing to participate, the volunteers received a diary to register their intercourses and correspondent use of male condom (MC). After 30 days, they returned to a training visit when the FC was inserted in a pelvic model, also bringing their diary related to the previous cycle, considered a control cycle. A structured questionnaire was used at 30, 60 and 90 days, also with the respective diary on sexual intercourse and use of MC and FC kept for posterior data entry. c², Fisher's exact, McNemar and Friedman tests were applied statistical analysis of paired samples. RESULTS: there was a predominance of young women, with low schooling, living with their partner. Rate of continuity was 52% after 90 days. The use of FC in half the intercourses for each time period remained stable over the 90-day interval. There was a significant reduction in unprotected intercourses (from 14 to 6%), without use of FC or MC, at the end of the period. The initial difficulties in handling the device were overcome. Serodiscordant couples had more protected intercourses than concordant couples, but the difference did not reach statistical significance. Women reporting consistent previous use of MC had more protected sex using FC. CONCLUSIONS: the offer of the female condom was able to reduce unprotected intercourses in HIV-infected women, which were highly motivated and receptive for the new method.

Most authors agree on the negative impact of pregnancy in women with advanced maternal age on maternal and perinatal outcome. However, it is not usual to evaluate if some considered risk factors are only confounders because they are present in women over forty years. In order to identify the isolated effect of age on maternal and perinatal outcome of pregnancies in women over forty, 494 pregnancies from this age group were compared to 988 pregnancies among women aged 20 to 29 years, matched by parity. After controlling possible confounding variables through multivariate analysis, advanced maternal age maintained its association with a higher prevalence of hypertension, malpresentation, cesarean section, postpartum hemorrhage, low Apgar score, perinatal death, late fetal death and intrapartum fetal distress. These findings show the need for adequate obstetrical care with special attention to those factors in order to improve maternal and perinatal outcome of pregnancies in women with advanced age.

Purpose: to report the personal experience with the use of the amnioinfusion technique in patients in labor presenting meconial amniotic fluid, and the incidence of complications, the meconium aspiration syndrome and of cesarean sections. Method: twenty patients at term and in labor with meconial amniotic fluid were evaluated retrospectively, at the delivery ward at two public institutions of Rio Grande do Sul. An initial infusion of 1.000 ml of normal saline solution at room temperature, at an infusion rate of 20-30 ml per minute was initiated and then reduced to 3 ml per minute. The liquid was drained by elevating the cephalic pole. Results: the procedure was feasible when a nasogastric catheter was used. None of the patients presented major complications related to the procedure. None of the neonates presented meconium below their vocal cords. The cesarean section rate was 3/20 (15%). Conclusion: the amnioinfusion is a low-cost and feasible technique that did not show any complication in this study.

Purpose: to study the influence of weight differences between twins on the perinatal results. Methods: the twin deliveries at the Maternity of the Hospital Regional de Clínicas de Sorocaba, SP, were retrospectively analyzed from July 1997 to June 1998. The samples were 89 mothers and their twins, divided into three classes of newborn weight differences, as follows: concordant (<15%), mild discordance (15 to 25%) and severe discordance (>25%). The independent variables analyzed were these three classes and the dependent variables were low weight at birth, Apgar index less than 7 at the first and fifth minute, premature delivery, time of permanence of the newborn in the nursery, and perinatal mortality coefficient I. Statistical analysis was performed using Kruskal-Wallis test, completed by Hollander test, and the Blackwell test. Results: the number of pregnancies (62, 17 and 10) and premature deliveries (32, 9 and 7) were observed respectively in the three classes. For the first and second twins we observed: low weight at birth (39/41, 13/12 and 8/9), Apgar index less than 7 at the first minute (16/13, 3/7 and 2/3), Apgar index at the fifth minute (4/4, 0/2 and 1/2), time (in days) of permanence of the newborn in the nursery (3.7/3.7, 4.6/6.0 and 7.3/8.7) and perinatal mortality coefficient I (22.4/16.8, 0/16.8 and 5.6/5.6). Conclusions: the incidence of weight discordance between twins was 30.3%, 19.1% being mild discordance and 11.2% severe discordance. There was a tendency to a progressive aggravation of perinatal results considering the degree of discordance of the classes (concordant < mild discordance < severe discordance).
