In the pregnancy-puerperal cycle, women may develop complications that require admission to the Intensive Care Unit (ICU). Thus, special attention to pharmacotherapy is necessary, particularly to potential drug interactions (PDIs) and to the effect of the drugs on the fetus and newborn.
The aim of this study was to determine the profile of PDIs and the potential risk of drugs used during pregnancy and breastfeeding among patients admitted to the ICU.
We conducted an observational, cross-sectional and prospective study, including pregnant and breastfeeding women admitted to the ICU at the Women’s Hospital of a university in the city of Campinas, Brazil, for one year. Online databases were used to identify and classify the PDIs and the potential risk of the drugs used during pregnancy and breastfeeding.
We evaluated 305 prescriptions of 58 women, 31 pregnant and 27 breastfeeding, and 284 (91%) prescriptions presented PDIs. A total of 175 different combinations of PDIs were identified in the prescriptions, and adverse effects caused by the simultaneous use of drugs were not actually observed in the clinical practice. A total of 26 (1.4%) PDIs were classified as contraindicated. We identified 15 (13.8%) drugs prescribed with risk D, and 2 (1.8%) with risk X for pregnant women, as well as 4 (4.9%) drugs prescribed with high risk for breastfeeding women.
This study demonstrates that there is a high incidence of PDIs in prescriptions. Most drugs used by pregnant and breastfeeding women at the ICU did not present serious risks to their fetus and newborns, but sometimes drugs with risk D or X are necessary in the course of the treatment.

To evaluate maternal-fetal surveillance and follow-up of infants at risk for congenital syphilis (CS).
Retrospective cohort study in a Portuguese Tertiary Referral Hospital. The main inclusion criterion was a positive syphilis serology. The study included all pregnant women that delivered in our hospital between January 2004 and December 2013. The neonates were classified according to their probability of infection based on the Centers for Disease Control and Prevention guidelines.
Among the 27 pregnancies at risk for CS, 48.2% (n = 13) of the women had a diagnosis during the 1st trimester, and the median gestational age at the end of the treatment was 28 weeks. Inadequate treatment was noted in 44.4% (n = 12) of the women. Adverse pregnancy outcomes were observed in 30.8% of the cases (n = 8), 5 of which had been adequately treated. We found 2 (7.7%) cases with “proven or highly probable CS,” 10 (38.5%) with “possible CS,” 12 (46.1%) with “less likely CS,” and 2 (7.7%) with “unlikely CS.”Among the infants, the treatment was successful, except for 1 neurosyphilis case.
This study highlights many of the difficulties/concerns encountered in the maternal-neonatal management of syphilis. We highlight the importance of assuring the early detection of the infection as a way of guaranteeing the timely treatment, as well as a good compliance to the treatment and follow-up through a more efficient pregnant women surveillance network.

To evaluate the magnitude of the association of the polymorphisms of the genes PGR, CYP17A1 and CYP19A1 in the development of endometriosis.
This is a retrospective case-control study involving 161 women with endometriosis (cases) and 179 controls. The polymorphisms were genotyped by real-time polymerase chain reaction using the TaqMan system. The association of the polymorphisms with endometriosis was evaluated using the multivariate logistic regression.
The endometriosis patients were significantly younger than the controls (36.0±7.3 versus 38.0±8.5 respectively, p = 0.023), and they had a lower body mass index (26.3±4.8 versus 27.9±5.7 respectively, p = 0.006), higher average duration of the menstrual flow (7.4±4.9 versus 6.1±4.4 days respectively, p = 0.03), and lower average time intervals between menstrual periods (25.2±9.6 versus 27.5±11.1 days respectively, p = 0.05). A higher prevalence of symptoms of dysmenorrhea, dyspareunia, chronic pelvic pain, infertility and intestinal or urinary changes was observed in the case group when compared with the control group. The interval between the onset of symptoms and the definitive diagnosis of endometriosis was 5.2±6.9 years. When comparing both groups, significant differences were not observed in the allelic and genotypic frequencies of the polymorphisms PGR + 331C > T, CYP17A1 -34A > G and CYP19A1 1531G > A, even when considering the symptoms, classification and stage of the endometriosis. The combined genotype PGR + 331TT/CYP17A1 -34AA/CYP19A11531AA is positively associated with endometriosis (odds ratio [OR] = 1.72; 95% confidence interval [95%CI] = 1.09-2.72).
The combined analysis of the polymorphisms PGR-CYP17A1-CYP19A1 suggests a gene-gene interaction in the susceptibility to endometriosis. These results may contribute to the identification of biomarkers for the diagnosis and/or prognosis of the disease and of possible molecular targets for individualized treatments.

The views of infertile couples regarding oocyte donation by third parties and adoption are unknown, as these may be interpreted as a final closure of the available options for conception. This study aimed to determine the acceptance of oocyte donation, oocyte reception, and child adoption of infertile women who submitted to assisted reproductive technology (ART) treatment
Sixty-nine women who were under treatment for infertility and submitted to ART procedures were included in this cross-sectional study. They were evaluated using semi-structured questionnaires administered during ovulation induction in a treatment cycle. Marital status, religion, years of schooling, occupation, type of infertility, age, duration of infertility, number of previous ART cycles, mean oocyte number per cycle, and mean number of embryos per cycle had no influence on a woman’s acceptance of oocyte donation or oocyte reception.
More than 90% of the patients thought that the subject of “adoption” should be brought up during their ART treatments, although they preferred to discuss this topic with psychologists, not doctors. Women with occupations were more willing to consider adoption.
The opinions of these patients on these issues seem to be based on personal concepts and ethical, religious, and moral values. Women preferred to discuss adoption with psychologists rather than doctors.

To evaluate the expressions of biomarkers p16 and Ki-67 in low-grade (LG) or high-grade (HG) lesions, and to relate them to risk factors and the recurrence of these lesions.
A retrospective case-control study of 86 patients with LG and HG lesions who underwent a loop electrosurgical excision procedure (LEEP) between 1999 and 2004. The control group was composed of 69 women with no recurrence, and the study group, of 17 patients with recurrence. All patients were followed-up over a two-year period after surgery, and screened every six months, including cytology and colposcopy. Biopsy samples collected from LEEP were submitted to immunohistochemical analysis for p16 and Ki-67. The statistical analysis was performed using the Statistical Package for the Social Sciences software (SPSS, IBM-SPSS, Inc., Chicago, IL, US), with a significant p < 0.05.
The biomarkers p16 and Ki-67, separately or combined, showed no relation to recurrence on the total analysis. However, evaluating specifically HG lesions, the positive expression (2+ and 3 + ) of p16/Ki-67 was associated with recurrence (0.010). In addition, p16 isolated was also more expressive in HG lesions (2+ and 3 + , p= 0.018), but it was unrelated to recurrence.
Proteins p16 and Ki-67, both isolated and combined, are not reliable primary markers for the recurrence of cervical lesions in the majority of LG lesions. However, analyzing only the group with prior diagnosis of HG lesions, the expressions of p16 and of p16/Ki-67 were associated with recurrence, and they may be useful in monitoring these cases.

Unwanted pregnancy is a major public health problem both in developed and developing countries. Although the reduction in the rates of these pregnancies requires multifactorial approaches, increasing access to long-acting contraceptive methods can contribute significantly to change this scenario. In Brazil, gynecologists and obstetricians play a key role in contraceptive counseling, being decisive in the choice of long-acting reversible methods, characterized by intrauterine devices (IUDs) and the contraceptive implant. The vast scope due to the reduced number of situations to indicate long-acting methods should be emphasized in routine contraceptive counseling. On the other hand, gynecologists and obstetricians should adapt the techniques of insertion of long-acting methods, and engage in facilitating conditions to access these contraceptives through public and private health systems in Brazil. This study is part of a project called Diretrizes e Recomendações FEBRASGO (Guidelines and Recommendations of the FEBRASGO - Brazilian Federation of Gynecology and Obstetrics Associations from the Portuguese acronym). It aims to review the main characteristics of long-acting contraceptives and critically consider the current situation and future prospects to improve access to these methods, proposing practical recommendations of interest in the routine of gynecologists and obstetricians.

To describe the prenatal diagnosis of Galen vein aneurysm (GVA) based on ultrasonography and magnetic resonance imaging (MRI) in a series of cases, as well as its postnatal outcomes and follow-up until 4 years of age.
A retrospective longitudinal study was performed, analyzing a database comprising seven cases of prenatal diagnosis of GVA at two Brazilian institutions from February of 2000 to May of 2012. The following data were evaluated: gestational age at diagnosis, GVA dimensions on ultrasonography, associated fetal changes, findings on fetal echocardiography, gestational age at delivery, type of delivery, birth weight, Apgar score at the 1st and 5th minutes, neonatal outcomes, and survival with follow-up until 4 years of age.
The mean gestational age ± standard deviation on the prenatal diagnosis of GVA based on ultrasonography was 25±4.9 weeks. The mean length of GVA was 3.2±0.4 cm. The mean gestational age at birth was 37.5±0.7 weeks, and a cesarean section was performed in 85.7% of the cases (6/7). The mean birth weight was 3,070±240.4 g. The total survival rate was 42.8% (4/7), with three neonatal deaths. Of the four survivors, three presented with normal neuropsychomotor development until 4 years of age and only one showed serious neurological sequelae. Ultrasonography and MRI showed similar findings for all seven cases.
Galen Vein Aneurysm is associated with a high neonatal death rate. Therefore, its prenatal diagnosis is essential for parent counseling and follow-up at tertiary care institutions.
