Síndromes hipertensivas da gestação e repercussões perinatais

OBJECTIVES: to assess perinatal effects of pregnancy hypertensive syndromes. METHODS: hospital-based observational and retrospective study of a tertiary Brazilian center, from January, 1996 to October, 2003. Twelve thousand and two hundred and seventy two (12.272) pregnancies met the inclusion criteria. Two types of hypertension were considered: gestational hypertension (GH) and chronic hypertension (CH). Results of the study demonstrated that newborns of mothers with gestational hypertension and chronic hypertension were small for gestational age (SGA), had low Apgar score in the 1o and 5o minutes, neonatal infection, meconium aspiration syndrome (MAS), prematurity and respiratory distress syndrome (RDS). RESULTS: 1259 (10.26%) had hypertension, 344 (2.80%) were classified as GH, 915 (7.45%) as CH and 11.013 (89.74%) had no hypertension. GH was risk factor for SGA, low Apgar score in the first and fifth minutes, neonatal infection and prematurity, but not for MAS and RDS. CH was a risk factor for SGA, low Apgar score in the first minute, MAS, prematurity and RDS, but not for low Apgar score in the fifth minute and neonatal infection. When comparing the relative risk between CH and GH an increased risk for prematurity in CH was determined. CONCLUSIONS: our data suggest that CH and GH increased the risks for the outcomes studied. An increased risk for prematurity in CH was noted.

Clinical and radiological correlations in patients with gestational trophoblastic disease

Gestational trophoblastic disease is an abnormality of pregnancy that encompasses a group of diseases that differ from each other in their propensity for regression, invasion, metastasis, and recurrence. In the past, it was common for patients with molar pregnancy to present with marked symptoms: copious bleeding; theca lutein cysts; uterus larger than appropriate for gestational age; early preeclampsia; hyperemesis gravidarum; and hyperthyroidism. Currently, with early diagnosis made by ultrasound, most patients are diagnosed while the disease is still in the asymptomatic phase. In cases of progression to trophoblastic neoplasia, staging-typically with Doppler flow studies of the pelvis and chest X-ray, although occasionally with computed tomography or magnetic resonance imaging-is critical to the choice of an appropriate antineoplastic therapy regimen. Because it is an unusual and serious disease that affects women of reproductive age, as well as because its appropriate treatment results in high cure rates, it is crucial that radiologists be familiar with gestational trophoblastic disease, in order to facilitate its early diagnosis and to ensure appropriate follow-up imaging.

A review of selected Arboviruses during pregnancy.

Arboviruses are emerging infectious diseases with the ability to expand geographically and rapidly affect large populations.The recent epidemic caused by the Zika virus in the Americas and congenital Zika syndrome associated with maternal infection has called out attention to the importance of studying arboviruses during pregnancy.This is a review on selected arboviruses infections during gestation, including Zika, Chikungunya, Dengue and Yellow Fever viruses. Issues such as historical overview, pathogenesis, transmission, clinical conditions, diagnosis, treatment and prevention are addressed.

Cesarean section by maternal request

Cesarean section by maternal request is the one performed on a pregnant woman without medical indication and without contraindication to vaginal delivery. There is great controversy over requested cesarean section. Potential risks include complications in subsequent pregnancies, such as uterine rupture, placenta previa and accreta. Potential benefits of requested cesareans include a lower risk of postpartum hemorrhage in the first cesarean and fewer surgical complications compared with vaginal delivery. Cesarean section by request should never be performed before 39 weeks. RESUMO A cesariana a pedido materno é aquela realizada em uma gestante sem indicações médicas e sem contraindicação para tentativa do parto vaginal. Existe grande controvérsia sobre a realização da cesariana a pedido. Riscos potenciais da cesariana a pedido incluem complicações em gravidezes subsequentes, tais como: rotura uterina, placenta prévia e acretismo. Potenciais benefícios da cesariana a pedido englobam um menor risco de hemorragia pós-parto na primeira cesariana e menos complicações cirúrgicas quando comparada ao parto vaginal. A cesariana a pedido jamais deve ser realizada antes de 39 semanas.

Preeclampsia: Prevalence and perinatal repercussions in a University Hospital in Rio de Janeiro, Brazil

Preeclampsia (PE) prevalence studies in Brazil are both scarce and not divided in accordance with gestational age at delivery. We accessed PE prevalence according to delivery before 34, 37 and 42weeks in a cross-sectional study including 4464 single deliveries. PE was diagnosed in 301 cases (6.74%); Prevalence of PE was 0.78%; 1.92% and 6.74% according to deliveries before 34, 37 and 42weeks. PE was associated with fetal death, prematurity and small for gestational age newborns.

Assistance flowchart for pain management in a Neonatal Intensive Care Unit

OBJECTIVE To describe and discuss the process of developing a flowchart collectively constructed by the health team of a Neonatal Intensive Care Unit for the management of neonatal pain. METHOD This is a descriptive and an exploratory study with a qualitative approach that used Problem-Based Learning as a theoretical-methodological framework in the process of developing the assistance flowchart for the management of neonatal pain. RESULTS Based on this methodology, there was training in service and the discussion of key points of pain management by the health team, which served as input for the construction of the flowchart. FINAL CONSIDERATIONS The assistance flowchart for pain management, based on scientific evidence, provided means to facilitate the decision-making of the health team regarding the pain of the newborn. It is suggested to use the flowchart frequently to promote the permanent education of the team and identify possible points to be adjusted.

Cantrell's Pentalogy in Twins: Prenatal Diagnosis.

The combination of an onphalocele, an anterior thoracic wall defect and an anterior diaphragmatic defect constitutes classical Cantrells pentalogy. We present a case of Cantrells pentalogy diagnosed prenataly in twins with conventional and three-dimensional sonography.

A twin pregnancy with a hydatidiform mole and a coexisting live fetus: prenatal diagnosis, treatment, and follow-up

Twin molar pregnancy with a hydatidiform mole and a coexisting live fetus is a rare form of gestational trophoblastic disease associated with an increased risk of obstetric complications and poor perinatal outcome. Prenatal diagnosis is essential for couple counseling and follow-up in Tertiary Reference Centers. Magnetic resonance imaging is important for the diagnostic differentiation of placental mesenchymal dysplasia and exclusion of myometrial invasion. Here we present a case of twin molar pregnancy with a hydatidiform mole and a coexisting live fetus diagnosed at gestational week 14 using two-dimensional (2D) and three-dimensional (3D) ultrasound and magnetic resonance imaging. We also describe the obstetric management and postmolar follow-up.

How do maternal factors impact preeclampsia prediction in Brazilian population

Abstract Objective: To evaluate the impacts of maternal risk factors described by the Fetal Medicine Foundation’s 2012 algorithm (FMF2012) in a Brazilian population. Methods: All singleton pregnancies submitted to first-trimester preeclampsia (PE) screening using the FMF2012 algorithm were considered for study inclusion. Maternal factors, recorded via a patient questionnaire, were described and compared between PE outcome groups. A Gaussian regression model was derived to measure the effects of maternal factors, and to identify factors that contributed significantly (p < .05) to the alteration of gestational age at delivery, in pregnancies with PE. Results: Of the 1934 cases considered for study inclusion, the final sample consisted of 1531 cases. The sample included 120 (7.8%) cases of PE, of which 26 (1.7%) were preterm PE (PE < 37 weeks) and 11 (0.72%) were early PE (PE < 34 weeks). The PE rate did not differ according to ethnicity, smoking, family history of PE, or use of assisted reproductive technology. Significant differences (p < .05) between the normal and PE groups in maternal age, maternal weight, previous history of PE, chronic hypertension, and types 1 and 2 diabetes were detected. Conclusions: The significance and magnitude of associations of maternal factors in our sample differed from those incorporated in the FMF2012 model, implying the need to derive a fitted model for our population.

Nursing care systematization in maternal and child service care: an action research

Aim: To implement the systematization of nursing care (SNC) in the Maternity School of the Federal University of Rio de Janeiro. Method: This is an action research. The theory chosen was that of Basic Human Needs as proposed by Wanda Horta. The ICNP® was selected as the single classification system for the terminology with regard to diagnoses, expected outcomes and nursing interventions. Data collection will be carried out in accordance with the implementation of the SNC in each sector of the institution, consisting of the following steps: documentary research based on documents produced by the nursing staff and on the nursing diagnoses of the patients; field research through systematic observation of the team work processes; and seminars. In order to analyze the data obtained in the survey of nursing problems, the terms extracted from the medical charts will be analyzed and classified according to the model of nursing diagnoses contained in ICNP® 2.0 .
