To analyze the relationship between route of delivery and other aspects of pregnancy and the occurrence of intracranial hemorrhage in newborns of very low weight at a teaching hospital in South Brazil.
A case-control study was conducted. Medical records of all patients who were born weighing ≤1,500 g and who were submitted to transfontanellar ultrasonography were analyzed from January 2011 to September 2014. The cases were newborns with diagnosis of intracranial hemorrhage, while newborns with regular exams were used as controls. Differences between groups were analyzed by the Student t test and by χ2 or Fisher exact tests, and association was determined using the odds ratio with a 95% confidence interval and α=5%.
A total of 222 newborns with birth weight ≤1,500 g were recorded; of these, 113 were submitted to transfontanellar ultrasonography and were included in the study. Sixty-nine (61.1%) newborns were diagnosed with intracranial hemorrhage (cases) and 44 (38.9%) showed no abnormal results (controls). Most cases had grade I hemorrhage (96.8%) originating from the germinative matrix (95.7%). The predominant route of delivery was caesarean section (81.2% of the cases and 72.7% of the controls). Five deaths were recorded (3 cases and 2 controls). Gestational age ranged from 24 to 37 weeks. Median birth weight was 1,205 g (range: 675-1,500 g). The median time of hospitalization was 52 days, ranging from 5 to 163 days.
Grade I intracranial hemorrhage from the germinative matrix was the most frequent. No differences were found between cases and controls for the variables studied. The small number of infants submitted to transfontanellar ultrasonography limited the sample size and the results of the study.

To determine the average age at the onset of menopause and to investigate menopausal symptoms in women in a metropolitan region in Southeastern Brazil.
A descriptive, exploratory, cross-sectional study was conducted with 749 women (a population-based household survey). The dependent variable was the intensity of menopausal symptoms assessed by th Menopause Rating Scale (MRS). The independent variables were sociodemographic data, health-related habits and problems, self-perception of health, and gynecological background. Statistical analysis was carried out by the χ2 test and Poisson regression using the backward selection criteria.
The mean age of the women was 52.5 (±4.4) years. With regard to menopausal status, 16% were premenopausal, 16% perimenopausal and 68% postmenopausal. The mean age at the onset of menopause was 46.5 (±5.8) years. The intensity of menopausal symptoms was defined according to the median MRS score and was considered severe for values above 8. Depression/anxiety (PR=1.8; 95%CI 1.5-2.2; p<0.01), rheumatic diseases (PR 1.5; 95%CI 1.2-1.7; p<0.01), self-perception of health as fair/poor/very poor (PR 1.4; 95% CI 1.2-1.7; p<0.01), history of abortion (PR 1.3; 95%CI 1.1-1.4; p<0.01), current or previous treatment for menopausal symptoms (PR 1.2; 95%CI 1.1-1.4; p<0.01), peri- or postmenopausal status (PR 1.4; 95%CI 1.1-1.7; p<0.01), number of normal deliveries >1 (PR 1.2; 95%CI 1.02-1.4; p<0.01) and asthma (PR 1.2; 95%CI 1.01-1.4; p<0.01) were associated with more severe menopausal symptoms. Older age (PR 0.96; 95%CI 0.96-0.97; p<0.01) was associated with less severe symptoms.
The severity of menopausal symptoms was related to a wild range of factors, especially presence of chronic diseases, a larger number of pregnancies, use of hormone therapy, and worse self-rated health. A better understanding of these factors can help to reduce the impact of symptoms on quality of life, and to identify groups of women who are likely to need more care during and beyond menopause.

To assess the reproductive outcomes after hysteroscopic septoplasty.
A retrospective observational study was performed with analysis of the medical records of 28 women with infertility or recurrent abortions undergoing hysteroscopic septoplasty. To evaluate reproductive outcomes we consulted the medical records of our hospital and of primary health care units between septoplasty and the present or first pregnancy. Primary outcomes were pregnancy rate, newborns, and abortions after septoplasty. Uterine septum was diagnosed by 2D or 3D ultrasound and classified according to the American Fertility Society. All procedures were performed in the follicular phase of the menstrual cycle using monopolar or bipolar energy and/or microscissors. To compare the reproductive outcomes before and after septoplasty we used Microsoft Excel and SPSS version 17. Fisher's exact test was considered statistically significant if p<0.05.
Hysteroscopic septoplasty was performed in 20 patients (72%) with secondary infertility and in 8 patients (28%) with primary infertility. The septum was incompletely removed during the first hysteroscopy in 5 cases (18%), which required a second surgery. One case was complicated with minor uterine perforation. After hysteroscopic septoplasty, 64% of women became pregnant and 48% live neonates were delivered; 4% of the patients had a tubal pregnancy; and 19% had miscarriages.
The results of this study are consistent with those described in the literature. Patients obtained a significant improvement of reproductive outcomes with a fivefold reduction in miscarriage rate after hysteroscopic septoplasty.

To describe the maternal and fetal outcomes with the use of the Foley catheter for induction of labor in high-risk pregnant women with previous caesarean section.
An interventive and descriptive study was conducted from November 2013 to June 2014. A total of 39 pregnant women at term, with a live fetus, cephalic presentation, estimated fetal weight <4,000 g, with previous cesarean section, medical indications for induction of labor, Bishop score ≤6 and amniotic fluid index >5 cm were included. A number 16F Foley catheter was introduced for a maximum of 24 hours, and was considered to be satisfactory when the patient began labor within 24 hours.
Labor was successfully induced in 79.5% of pregnant women. Nine women achieved vaginal delivery (23.1%), with a frequency of 18% of vaginal births occurring within 24 hours. The main indications for the induction of labor were hypertensive disorders (75%). The mean interval between the placement of the Foley catheter and the beginning of labor and delivery were 8.7±7.1 and 14.7±9.8 hours, respectively. Meconium-stained amniotic fluid was observed in two patients; and an Apgar score <7 in the first minute was detected in 5 newborns (12.8%).
The Foley catheter is an alternative for the induction of labor in women with previous caesarean section, despite the low vaginal delivery rate.

It was to compare the use of two growth curves for the diagnosis of small-for-gestational-age (SGA) infants, having the 10thpercentile as reference.
In a retrospective study, data of 20,567 singleton live births from January 2003 to June 2014 were analyzed, and divided according to gestational age: (a) 23 to 26, (b) 26 to 29, (c) 29 to 32, (d) 32 to 35, (e) 35 to 38, (f) 38 to 41 and (g) >41 weeks. Data were paired and analyzed using the McNemar test, with the level of significance set at 0.05.
The curve designed by Alexander indicated a higher percentage of diagnosis of SGA than the curve constructed by Fenton for every category of gestational age up to 41 weeks, more markedly in the 32-35 week group (18.5%). Between 37 and 40 weeks of gestational age, Alexander's curve exceeded Fenton's curve in 9.1% of the cases in the diagnosis of SGA.
The Fenton curve provides a more accurate evaluation of an infant's growth since it is gender-specific and allows measurement of three parameters. It has also been constructed with newer data and more sophisticated statistical tools.

To assess the relationship between the histological classification and the quality of life of patients operated for endometriosis. METHODS: A cross-sectional observational study, with assessment of 32 biopsies of the intestine, peritoneum and uterosacral ligament from 40 women with deep endometriosis. The quality of life (QOL) was determined by applying the SF-36 questionnaire pre-operatively and at 6 and 12 months postoperatively. Biopsies were histologically classified into pure stromal (EP), glandular differentiated (GD), glandular undifferentiated (GI) and mixed (GM), remaining in the sample only GI and GM, which are related to eight domains of the SF-36.
According to the histologic type, the following distribution was observed: peritoneum 63% GI and 35% GM; intestine 19% GI and 24% GM; uterosacral ligament with 41% GI and 35% GM. Regarding the QOL and the histological classification, in the intestine only GM was associated with improvement of social and emotional aspects from 0 to 6 months; the domains general health status (p=0.01) and social aspect (p=0.04) were significantly related to improvement of the QOL from 0 to 6 months, and the general health status tended to improve from 0 to 12 months. Regarding pain (p=0.06) and the emotional aspect (p=0.05), the QOL tended to improve from 0 to 6 months and the vital capacity (p=0.1) improved from 0 to 6 months and from 0 to 12 months. Regarding the emotional aspect, evolution of the two histological types was not favorable for improvement in MG from 0 to 6 months. No significant relationships between histologic type and QOL were evident in the uterosacral ligament samples.
Improvement in the QOL of women undergoing laparoscopic surgery for deep endometriosis is associated with the histologic grade. The peritoneal biopsy of GI revealed improved QOL after surgery.

The aim of this study was to compare the performance of two human papillomavirus (HPV) genotyping techniques, Linear Array and PapilloCheck, in women with high-grade squamous intraepithelial lesion (HSIL).
A total of 88 women with cytological diagnosis of HSIL were recruited at 2 reference centers in cervical pathology in Salvador, Bahia, Brazil, from July 2006 to January 2009. After the cytological diagnosis of HSIL, cervix cells were collected to determine the HPV genotype and a biopsy was obtained under colposcopic vision for histopathological analysis. After the confirmation of CIN2+ by histopathology, HPV genotyping was performed on 41 women by the Linear Array and PapilloCheck methods.
Both tests showed an overall concordance rate for HPV detection of 97.2% (35/36). Of the 36 valid samples, 35 (97.2%) were positive in both tests and 1 (2.8%) was discordant, with the Linear Array indicating the presence of multiple types. The most prevalent HPV genotypes detected by the Linear Array technique were HPV 16, HPV 56, HPV 35, HPV 45, and HPV 70; and those detected by the PapilloCheck technique were HPV 16, HPV 56, HPV 11, HPV 35, and HPV 42. A similar rate of infection with multiple HPV types was observed with the two tests (72.5% with the Linear Array and 75.0% with the PapilloCheck).
Linear Array genotyping assay and PapilloCheck showed equivalent performance for the detection of oncogenic HPV types in women with HSIL, with PapilloCheck having the advantage of being a method that avoids subjectivity when reading the HPV genotypes.

To analyze the risk factors for urinary incontinence (UI) in older women practicing physical exercises (PE).
A total of 152 older women with a mean age of 68.6±5.8 years who regularly practiced PE participated in the study. The presence of UI and gynecological, obstetric, clinical, behavioral, hereditary and anthropometric risk factors was determined identified. It was also applied the Domain 4 of the International Physical Activity Questionnaire (IPAQ) to determine the level of physical activity and body mass index and waist circumference were measured. Data were analyzed using descriptive and inferential statistics, with the level of significance set at 5%.
The prevalence of UI in the sample was 32.2%. Among the factors evaluated, only the use of diuretics (OR=2.7; 95%CI 1.0-7.0) and a positive family history of urinary incontinence (OR=2.3; 95%CI 1.1-4.8) were associated with UI symptoms.
The use of diuretics is considered to be a modifiable risk factor for UI, whereas a family history is not considered to be a modifiable risk factor.
