Câncer de colo uterino na gestação / Cervical cancer in pregnancy

PONTOS-CHAVE • A incidência de câncer durante a gestação tem aumentado devido à tendência das mulheres em postergar a gravidez. O câncer de colo de útero é a terceira neoplasia mais comumente diagnosticada durante o período gestacional. • O rastreamento e o diagnóstico devem se dar como nas pacientes não gestantes; a citologia oncótica cervical é o exame obrigatório do pré-natal, e a colposcopia com biópsia pode ser realizada em qualquer período da gestação. • A gestação complicada pelo diagnóstico de um câncer deve sempre ser conduzida em centro de referência e por equipe multidisciplinar. • A interrupção da gestação em situações específicas, para tratamento-padrão, é respaldada por lei. • A quimioterapia neoadjuvante é uma alternativa segura de tratamento durante a gestação, para permitir alcançar a maturidade fetal. Apresenta altas taxas de resposta, sendo relatada progressão neoplásica durante a gestação em apenas 2,9% dos casos. O risco de malformações fetais decorrentes da quimioterapia é semelhante ao da população geral. Contudo, a quimioterapia está associada a restrição de crescimento intraútero, baixo peso ao nascer e mielotoxicidade neonatal. • Na ausência de progressão de doença, deve-se levar a gestação até o termo.

Microcarcinoma papilar de tiroides: vigilancia activa. Revisión de la bibliografía / Papillary thyroid microcarcinoma: active surveillance. Literature review

El cáncer de tiroides ha aumentado en incidencia, sin embargo, la mortalidad se mantiene estable. Muchas de estas lesiones son a expensas de un microcarcinoma papilar de tiroides definido por la OMS como aquel carcinoma papilar de tiroides que en su diámetro máximo no sobrepasa los 10 mm. El avance de la imagenología sobre todo la ecografía de alta resolución y el hallazgo en pieza de anatomía patológica por lesiones benignas son las principales causas del aumento en el diagnóstico de esta entidad. La vigilancia activa surge entonces como alternativa de manejo para pacientes portadores de microcarcinoma papilar con bajo riesgo de progresión, obteniendo resultados oncológicos comparables. Independiente de su tratamiento el pronóstico de estos pacientes es excelente con sobrevida cercana al 100% en 10 años. A pesar de lo dicho la morbilidad de las distintas opciones terapéuticas es muy distinta. Será fundamental buscar elementos clínicos y paraclínicos que permitan tomar una decisión práctica, con el fin de determinar qué pacientes con microcarcinomas papilares que podrán entrar en un protocolo de vigilancia activa. Esta revisión pretende examinar la bibliografía publicada al respecto como alternativa de manejo, y su eventual aplicación en Uruguay.

Thyroid cancer has increased in incidence; however, mortality remains stable. Many of these lesions are at the expense of papillary thyroid microcarcinoma defined by the WHO as papillary thyroid carcinoma that in its maximum diameter does not exceed 10 mm. The advance of imaging, especially high-resolution ultrasound and the finding of benign lesions in pathological anatomy specimens are the main causes of the increase in the diagnosis of this entity. Active surveillance arises then as a management alternative for patients with papillary microcarcinoma with low risk of progression, obtaining comparable oncologic results. Regardless of their treatment, the prognosis of these patients is excellent with a survival rate close to 100% in 10 years. In spite of what has been said, the morbidity of the different therapeutic options is very different. It will be essential to look for clinical and paraclinical elements that will allow making a practical decision, in order to determine which patients with papillary microcarcinomas will be able to enter an active surveillance protocol. This review aims to examine the literature published on this subject as a management alternative, and its eventual application in Uruguay.

Discussion on how to optimize active surveillance for low-risk papillary thyroid microcarcinoma in China / 中华外科杂志

Active surveillance, as a first-line treatment strategy for low-risk papillary thyroid microcarcinoma, has been recommended by guidelines worldwide. However, active surveillance has not been widely accepted by doctors and patients in China. In view of the huge challenges faced by active surveillance, doctors should improve their understanding of the "low risk" of papillary thyroid micropapillary cancer, identify some intermediate or high-risk cases, be familiar with the criteria and methods of diagnosis for disease progression, and timely turn patients with disease progression into more active treatment strategies. By analyzing the long-term cost-effectiveness of active surveillance, it is clear that medical expense is only one cost form of medical activities, and the health cost (thyroid removal and surgical complications) paid by patients due to"over-diagnosis and over-treatment" is the most important. Moreover, the weakening of the patients' social function caused by surgical procedures is a more hidden and far-reaching cost. The formulation of health economic policies (including medical insurance) should promote the adjustment of diagnosis and treatment behavior to the direction which is conducive to the long-term life and treatment of patients, improving the overall health level of society and reducing the overall cost. At the same time, doctors should stimulate the subjective initiative of patients, help them fully understand the impact of various treatment methods on their psychological and physical status, support patients psychologically, and strengthen their confidence in implementing active surveillance. By strengthening multi-disciplinary treatment team and system support, doctors can achieve risk stratification of papillary thyroid microcarcinoma, accurate judgment of disease progress, timely counseling for psychological problems, and long-term adherence to active surveillance. Improving the treatment level of advanced thyroid cancer is the key point of improve the prognosis. It is important to promote the development of active surveillance for low-risk papillary thyroid microcarcinoma. In the future, it is necessary to carry out multi-center prospective research and accumulate research evidence for promoting the standardization process of active surveillance. Standardized active surveillance will certainly benefit specific papillary thyroid microcarcinoma patients.

Implementing active surveillance for tuberculosis: The experiences of healthcare workers at four sites in two provinces in South Africa

The high burden of tuberculosis (TB) in South Africa (SA) is associated with uncontrolled transmission in communities and delayed diagnosis of active cases. Active surveillance for TB is provided by community-based services (CBS). Research is required to understand key factors influencing TB screening services in the CBS. This study explored the implementation of active surveillance for TB where community-oriented primary care (COPC) had been successfully implemented to identify these factors.Methods: This was a qualitative study of four established COPC sites across two provinces in SA where active surveillance for TB is implemented. Semi-structured interviews were conducted with purposively selected healthcare workers in the CBS and citizens in these communities. The recorded interviews were transcribed for data analysis using ATLAS.tisoftware.Results: The factors influencing active surveillance for TB were directly related to the major players in the delivery of CBS. These factors interacted in a complex network influencing implementation of active surveillance for TB. Building effective relationships across stakeholder platforms by community health workers (CHWs) was directly influenced by the training, capacity building afforded these CHWs by the district health services; and acceptability of CBS. Each factor interplayed with others to influence active surveillance for TB.Conclusion: Community health workers were central to the success of active surveillance for TB. The complex interactions of the social determinants of health and TB transmission in communities required CHWs to develop trusting relationships that responded to these issues that have impact on TB disease and linked clients to healthcare.Keywords: tuberculosis; active case finding; community-oriented primary care; community health worker (CHW); community-based services; active surveillance.

Vigilância ativa do câncer de próstata - um conceito em evolução / Active surveillance of prostate cancer - an ongoing concept

A vigilância ativa é a solução encontrada pela urologia para a condução de tumores prostáticos com características de pouca agressividade. Desenvolvida especialmente após as polêmicas que envolveram a validade do rastreamento, essa abordagem vem sendo consolidada como a melhor maneira de se evitar o tratamento desnecessário do câncer de próstata e precisa ser compreendida por todos os médicos que lidam com a saúde do homem.

Active surveillance is the solution found by urology to deal with low-aggressivity prostate tumours. Having been developed following controversies over screening strategies, this has been considered the best approach to avoid unnecessary treatment of prostate cancer and such a concept needs to be well understood by every medical doctor who deals with men's health.

The comparison of survival between active surveillance or watchful waiting and focal therapy for low-risk prostate cancer: a real-world study from the SEER database / 亚洲男科学杂志(英文版)

To reduce treatment-related side effects in low-risk prostate cancer (PCa), both focal therapy and deferred treatments, including active surveillance (AS) and watchful waiting (WW), are worth considering over radical prostatectomy (RP). Therefore, this study aimed to compare long-term survival outcomes between focal therapy and AS/WW. Data were obtained and analyzed from the Surveillance, Epidemiology, and End Results (SEER) database. Patients with low-risk PCa who received focal therapy or AS/WW from 2010 to 2016 were included. Focal therapy included cryotherapy and laser ablation. Multivariate Cox proportional hazards models were used to compare overall mortality (OM) and cancer-specific mortality (CSM) between AS/WW and focal therapy, and propensity score matching (PSM) was performed to reduce the influence of bias and unmeasured confounders. A total of 19 292 patients with low-risk PCa were included in this study. In multivariate Cox proportional hazards model analysis, the risk of OM was higher in patients receiving focal therapy than those receiving AS/WW (hazard ratio [HR] = 1.35, 95% confidence interval [CI]: 1.02-1.79, P = 0.037), whereas no significant difference was found in CSM (HR = 0.98, 95% CI: 0.23-4.11, P = 0.977). After PSM, the OM and CSM of focal therapy and AS/WW showed no significant differences (HR = 1.26, 95% CI: 0.92-1.74, P = 0.149; and HR = 1.26, 95% CI: 0.24-6.51, P = 0.782, respectively). For patients with low-risk PCa, focal therapy was no match for AS/WW in decreasing OM, suggesting that AS/WW could bring more overall survival benefits.

Detección rápida de Enterobacterias productoras de carbapenemasas en hisopados rectales de pacientes neonatos colonizados / Rapid detection of carbapenemase-producing Enterobacteriaceae in rectal swabs of colonized neonatal patients

Resumen Objetivo: Detectar la presencia de Enterobacterias productoras de carbapenemasas en hisopados rectales de neonatos mediante técnica de nefelometría láser y caracterización del tipo de carbapenemasa mediante test inmunocromatográfico. Materiales y Métodos: Estudio descriptivo de corte transversal. Fueron incluidos 57 neonatos, tamizados al ingreso a UCI, mediante hisopado rectal, procesado por nefelometría laser HB&L Carbapenemase (Alifax®) y caracterización del tipo de carbapenemasa por inmunocromatografía rápida RESIST-3 (Coris BioConcept®). Resultados: Encontramos un alto porcentaje de colonización rectal (22.9%) correspondiente a 13 hisopados positivos y 44 (77.1%) fueron negativos por nefelometría láser. Por VITEK 2® se obtuvo identificación de Klebsiella pneumoniae resistente a carbapenémicos en los 13 aislamientos y el test inmunocromatográfico reveló la presencia de carbapenemasas blaKPC en estos aislamientos. Discusión: Estudios evidencian el aumento de la colonización por microorganismos productores de carbapenemasas en neonatos. Los resultados de este estudio demuestran que un porcentaje significativo de neonatos que ingresan a las Unidades de Cuidado Neonatal se encuentran colonizados con Enterobacterias productoras de carbapenemasas en tracto intestinal. Lo anterior constituye un riesgo potencial para su diseminación y posterior desarrollo de brotes, en donde surge la importancia de implementar estrategias de vigilancia activa como la tamización rectal para la detección oportuna de neonatos colonizados.

Abstract Objective: To detect the presence of carbapenemase-producing Enterobacteriaceae in rectal swabs of neonates by means of laser nephelometry technique and characterization of the type of carbapenemase by immunochromatographic test. Materials and Methods: Descriptive cross-sectional study. 57 neonatal patients were included; They underwent rectal screening upon admission to the ICU, using swabs which were processed by HB&L Carbapenemase laser nephelometry (Alifax®) and characterization of the type of carbapenemase by RESIST-3 rapid immu nochromatography (Coris BioConcept®). Results: We found a high percentage of rectal colonization (22.9%) corresponding to 13 positive swabs and 44 samples (77.1%) were negative by laser nephelome try. Identification of carbapenem-resistant Klebsiella pneumoniae was obtained by VITEK 2® in the 13 isolates and the immunochromatographic test revealed the presence of blaKPC carbapenemases in these isolates. Discussion: Studies show increased colonization by carbapenemase-producing microorganisms in neonates. The results of this study demonstrate that a significant percentage of neonates who enter Neonatal Care Units are colonized with Enterobacteriaceae that produce carbapenemases in the intestinal tract. This constitu tes a potential risk for its spread and subsequent development of outbreaks, where the importance of implementing active surveillance strategies such as rectal screening for the timely detection of colonized neonates arises.

Preterm premature rupture of membranes: management between 28 and 34 weeks of pregnancy / Ruptura prematura de membranas pré-termo: conduta entre 28 e 34 semanas de gestação

INTRODUCTION: Premature rupture of membranes remains a challenge for professionals due to the high rates of maternal and neonatal morbidity and mortality, mainly related to complications resulting from prematurity. OBJECTIVE: To analyze the scientific production about premature rupture of membranes in pregnancies above 28 weeks and below 34 weeks. METHODS: Integrative literature review carried out in the Lilacs, SciELO, Medline and Cochrane Library databases, between 2014 and 2018, in Portuguese, English and Spanish, including original articles, available in full online, with free access, that addressed the study theme, using the keywords "premature rupture of ovular membranes", "premature labor" and "pregnancy complications" combined using the Boolean operators "AND" and "OR". RESULTS: Fourteen studies were included. It was possible to highlight the main recommendations regarding preterm premature rupture of membranes, divided into six categories for discussion, namely: indications for expectant management and delivery induction, prophylactic antibiotic therapy, prenatal corticosteroids, use of tocolytics, recommendations regarding the use of magnesium sulfate and amniocentesis. CONCLUSION: It was identified that expectant management is the ideal approach, with constant monitoring of the pregnant woman and the fetus, in addition to the administration of prophylactic antibiotics and prenatal corticosteroids, in the face of premature rupture of membranes in pregnancies between 28 and 34 weeks in order to provide the best maternal and perinatal results, guiding health professionals to evidence-based practice.

INTRODUÇÃO: A ruptura prematura de membranas continua a ser um desafio para os profissionais devido às altas taxas de morbimortalidade materna e neonatal, relacionada principalmente às complicações decorrentes da prematuridade. OBJETIVO: Analisar a produção científica acerca das evidências frente a ruptura prematura de membranas em gestações acima de 28 semanas e abaixo de 34 semanas. MÉTODOS: Revisão integrativa da literatura realizada nas bases de dados Lilacs, SciELO, Medline e Cochrane Library, entre 2014-2018, em português, inglês e espanhol, incluídos artigos originais, disponíveis completos online, com acesso livre, que abordassem a temática do estudo, utilizando os descritores "ruptura prematura de membranas ovulares", "trabalho de parto prematuro" e "complicações na gravidez" combinados por meio dos operadores booleanos "AND" e "OR". RESULTADOS: Foram incluídos 14 estudos, nos quais foi possível evidenciar as principais recomendações frente a ruptura prematura de membranas fetais pré-termo, divididos em seis categorias para discussão, sendo elas: indicações para o manejo expectante e indução do parto, antibioticoterapia profilática, corticosteroides pré-natais, uso de tocolíticos, recomendações quanto ao uso de sulfato de magnésio e realização de amniocentese. CONCLUSÃO: O estudo possibilitou identificar que o manejo expectante é a conduta ideal, com monitorização constante da gestante e do feto, além da administração de antibióticos profiláticos e corticosteroides pré-natais, frente a ruptura prematura de membranas em gestações entre 28 e 34 semanas a fim de proporcionar os melhores resultados maternos e perinatais, guiando os profissionais da saúde para uma prática baseada em evidências.

Pros and cons of perioperative therapy in the protection of organ function in rectal cancer / 中华胃肠外科杂志

The goal of rectal cancer treatment should be to better protect organ function and improve patients' quality of life on the basis of ensuring radical resection. The current evidence has proved the superiority of perioperative chemoradiotherapy in reducing local recurrence and improving long-term survival. From the perspective of organ function protection, however, perioperative chemoradiotherapy has both disadvantages and advantages. Despite the great help in improving long-term outcomes, adverse reactions of chemoradiotherapy can aggravate defecation, urination and sexual dysfunction. Also, for patients with significant or complete remission, if the treatment strategy of local resection or close follow-up is selected, organ function can be preserved to the greatest extent. The key to the choice of treatment is to evaluate preoperatively whether pathological complete response is achieved. It should be kept in mind that preserving organ itself is not the same as protecting organ function. For patients who need perioperative chemoradiation, the optimal treatment methods should be chosen based on the patient's condition. Surgeons should fully evaluate organ function before operation, select the appropriate treatment strategy, pay special attention to the protection of important organs and nerves during surgeries, and carry out close postoperative follow-up and organ function rehabilitation as soon as possible, so as to reduce the incidence of dysfunction and the impact on the quality of life.

Expectant Versus Interventionist Care in the Management of Severe Preeclampsia Remote from Term: A Systematic Review / Cuidado expectante versus cuidado intervencionista no tratamento da pré-eclâmpsia grave a distância: uma revisão sistemática

Abstract Objective To compare the effects of expectant versus interventionist care in the management of pregnant women with severe preeclampsia remote from term. Data sources An electronic search was conducted in the Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE), Cochrane Central Register of Controlled Trials (CENTRAL), Latin American and Caribbean Health Sciences Literature (LILACS, for its Spanish acronym), World Health Organization's International Clinical Trials Registry Platform (WHO-ICTRP), and Open- Grey databases. The International Federation of Gynecology and Obstetrics (FIGO, for its French acronym), Royal College of Obstetricians and Gynaecologists (RCOG), American College of Obstetricians and Gynecologists (ACOG), and Colombian Journal of Obstetrics and Gynecology (CJOG) websites were searched for conference proceedings, without language restrictions, up to March 25, 2020. Selection of studies Randomized clinical trials (RCTs), and non-randomized controlled studies (NRSs) were included. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach was used to evaluate the quality of the evidence. Data collection Studies were independently assessed for inclusion criteria, data extraction, and risk of bias. Disagreements were resolved by consensus. Data synthesis Four RCTs and six NRS were included. Low-quality evidence from the RCTs showed that expectant care may result in a lower incidence of appearance, pulse, grimace, activity, and respiration (Apgar) scores<7 at 5 minutes (risk ratio [RR]: 0.48; 95% confidence interval [95%CI]: 0.23%to 0.99) and a higher average birth weight (mean difference [MD]: 254.7 g; 95%CI: 98.5 g to 410.9 g). Very low quality evidence from the NRSs suggested that expectant care might decrease the rates of neonatal death (RR: 0.42; 95%CI 0.22 to 0.80), hyalinemembrane disease (RR: 0.59; 95%CI: 0.40 to 0.87), and admission to neonatal care (RR: 0.73; 95%CI: 0.54 to 0.99). Nomaternal or fetal differences were found for other perinatal outcomes. Conclusion Compared with interventionist management, expectant care may improve neonatal outcomes without increasing maternal morbidity and mortality.

Resumo Objetivo Comparar os efeitos dos cuidados expectantes versus intervencionistas no manejo de gestantes com pré-eclâmpsia grave distante do termo. Fontes de dados Foi realizada uma busca eletrônica no Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database (EMBASE), Cochrane Central Register of Controlled Trials (CENTRAL), Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS, para o espanhol) acrônimo), Plataforma Internacional de Registro de Ensaios Clínicos da Organização Mundial da Saúde (OMS-ICTRP) e bancos de dados OpenGrey. Foram pesquisados os sites da Federação Internacional de Ginecologia e Obstetrícia (FIGO, por sua sigla em francês), do Royal College of Obstetricians e Ginecologistas (RCOG), do American College of Obstetricians e Ginecologistas (ACOG) e do Colombian Journal of Obstetrics and Gynecology (CJOG) procedimentos da conferência, sem restrições de idioma, até 25 de março de 2020. Seleção de estudos Ensaios clínicos randomizados (RCTs) e estudos controlados não randomizados (NRSs) foram incluídos. A abordagem de Classificação de Recomendações, Avaliação, Desenvolvimento e Avaliação (GRADE) foi usada para avaliar a qualidade da evidência. Coleta de dados Os estudos foram avaliados de forma independente quanto aos critérios de inclusão, extração de dados e risco de viés. As discordâncias foram resolvidas por consenso. Síntese de dados Quatro RCTs e seis NRS foram incluídos. Evidências de baixa qualidade dos ECRs mostraram que o cuidado expectante pode resultar em uma incidência menor de pontuações de aparência, pulso, careta, atividade e respiração (Apgar) <7 em 5 minutos (razão de risco [RR]: 0,48; intervalo de confiança de 95% [IC 95%]: 0,23% a 0,99) e um peso médio ao nascer superior (diferença média [MD]: 254,7 g; IC 95%: 98,5 ga 410,9 g). Evidências de qualidade muito baixa dos NRSs sugeriram que os cuidados expectantes podem diminuir as taxas de morte neonatal (RR: 0,42; IC de 95% 0,22 a 0,80), doença da membrana hialina (RR: 0,59; IC de 95%: 0,40 a 0,87) e admissão à assistência neonatal (RR: 0,73; IC 95%: 0,54 a 0,99). Nenhuma diferença materna ou fetal foi encontrada para outros resultados perinatais. Conclusão Em comparação com o manejo intervencionista, o cuidado expectante pode melhorar os resultados neonatais sem aumentar a morbidade e mortalidade materna.

Active surveillance of carbapenem-resistant Gram-negative healthcare-associated infections in a low-middle-income country city

ABSTRACT Background: Carbapenem-resistance in healthcare-associated infections (HCAIs) is of great concern, and it is urgent to improve surveillance. We aimed to describe and analyze HCAIs trends on Gram-negative antimicrobial susceptibility in a city from a developing country, following the implementation of an active surveillance program. Methods: This is an aggregated study describing data from 24 hospitals with intensive care units, including a trend analysis by Joinpoint regression between January 2012 and December 2017. Results: There were 23,578 pathogens in 39,832 HCAIs, from which 16,225 were Gram-negatives (68.8%). Carbapenem susceptibility was lowest in A. baumannii (15.4-25.9%), K. pneumoniae (51.0-55.9%), and P. aeruginosa (64.9-84.1%) and highest in E. coli (96.5-99.2%). Only K. pneumoniae showed a significant Joinpoint at 95% confidence interval: −10.71% (−18.02; −2.75) from 2012 to 2014, p = 0.02, and 6.54% (−2.00; 15.83) from 2015 to 2017, p = 0.12, which was most influenced by urinary tract infections: −9.98% (−16.02; −3.48) from 2012 to 2014, p = 0.01, and 9.66% (−1.75; 22.39) from 2015 to 2017, p = 0.09. Conclusion: Although we found a significant change toward an improvement in carbapenem susceptibility in K. pneumoniae, resistance is high for most pathogens. These data should encourage health institutions to improve their prevention and control strategies.

Parto gemelar diferido: a propósito de un caso / Delayed twin birth: case report

INTRODUCCIÓN: Se presenta el caso de un parto diferido en una gestación gemelar en la que se consigue retrasar el parto del segundo gemelo 45 días con manejo conservador. CASO CLÍNICO: Mujer de 25 años, gestación gemelar bicorial biamniótica, con diagnóstico de muerte fetal del primer gemelo en semana 24+3 y parto del mismo tras una semana de evolución. Se decide la opción de tratamiento conservador expectante, con reposo absoluto, manteniendo tocolisis intravenosa, controles analíticos seriados, controles cardiotocográficos diarios, profilaxis antibiótica y antitrombótica. Con ello se consigue diferir el parto un total de 45 días. CONCLUSIÓN: El parto diferido en gestaciones gemelares es una práctica poco habitual, por lo que se carece de protocolos y actuaciones específicas. La bibliografía disponible difiere en cuanto al manejo de dichos casos y en el total de días que se consigue diferir el parto, pero en todos los estudios se reporta el beneficio en términos de resultados perinatales al conseguir aumentar la edad gestacional del segundo gemelo. En nuestro caso se consiguió una mejora sustancial del resultado perinatal asociado a la prematuridad sin importantes efectos adversos maternos y tras el periodo de latencia indicado.

INTRODUCTION: We report a delayed delivery of a dichorionic diamniotic twin pregnancy, in which the birth of the second twin was postponed 45 days. CASE REPORT: At 24+3 weeks of gestation, a 25-year-old woman with dichorionic diamniotic twin pregnancy presented with preterm premature rupture of membranes and intrauterine dead of the first fetus. Spontaneous delivery of the first death twin, occurred al 25+2 weeks. Tocolysis, antibiotic, antithrombotic prophylaxis, absolute rest, serial blood tests and fetal cardiotocography controls, were performed. The second twin was delivered at 31+5 weeks, after a the preterm premature rupture of membranes triggered the labor. The interval between the first and second birth was 45 days. CONCLUSION: Delayed delivery in twin pregnancies, is an uncommon clinical situation, so there are not validated medical protocols. Available bibliography offers different practices related to its management. Most studies confirm the better survival rate and perinatal outcomes of the postponed birth twin.

Active versus expectant management for preterm premature rupture of membranes at 34-36 weeks of gestation and the associated adverse perinatal outcomes / Manejo ativo versus expectante para ruptura prematura de membranas entre 34 e 36 semanas de gestação e os resultados perinatais adversos associados

Abstract Objective: To compare the type of management (active versus expectant) for preterm premature rupture of membranes (PPROM) between 34 and 36 + 6 weeks of gestation and the associated adverse perinatal outcomes in 2 tertiary hospitals in the southeast of Brazil. Methods: In the present retrospective cohort study, data were obtained by reviewing the medical records of patients admitted to two tertiary centers with different protocols for PPROM management. The participants were divided into two groups based on PPROM management: group I (active) and group II (expectant). For statistical analysis, the Student t-test, the chi-squared test, and binary logistic regression were used. Results: Of the 118 participants included, 78 underwent active (group I) and 40 expectant management (group II). Compared with group II, group I had significantly lower mean amniotic fluid index (5.5 versus 11.3 cm, p = 0.002), polymerase chain reaction at admission (1.5 versus 5.2 mg/dl, p = 0.002), time of prophylactic antibiotics (5.4 versus 18.4 hours, p < 0.001), latency time (20.9 versus 33.6 hours, p = 0.001), and gestational age at delivery (36.5 versus 37.2 weeks, p = 0.025). There were no significant associations between the groups and the presence of adverse perinatal outcomes. Gestational age at diagnosis was the only significant predictor of adverse composite outcome (x2 [1] = 3.1, p = 0.0001, R2 Nagelkerke = 0.138). Conclusion: There was no association between active versus expectant management in pregnant women with PPROM between 34 and 36 + 6 weeks of gestation and adverse perinatal outcomes.

Resumo Objetivo: Comparar o tipo de manejo (ativo versus expectante) para ruptura prematura de membranas (PPROM, na sigla em inglês) entre 34 e 36 semanas e 6 dias de gestação e os resultados perinatais adversos relacionados, em 2 hospitais terciários do sudeste brasileiro. Métodos: No presente estudo de coorte retrospectivo, os dados foram obtidos através da revisão dos prontuários de gestantes internadas em dois centros terciários com protocolos diferentes para o seguimento da PPROM. As gestantes foram divididas em dois grupos com base no manejo da PPROM: grupo I (ativo) e grupo II (expectante). Para análise estatística, foram utilizados o teste t de Student, qui-quadrado e regressão logística binária. Resultados: Das 118 gestantes incluídas, 78 foram submetidas a tratamento ativo (grupo I) e 40 a seguimento expectante (grupo II). Comparado ao grupo II, o grupo I apresentou índice de líquido amniótico médio significativamente menor (5,5 versus 11,3 cm, p = 0,002), reação em cadeia da polimerase na admissão (1,5 versus 5,2 mg/dl, p = 0,002), tempo de antibióticos profiláticos (5,4 versus 18,4 horas, p < 0,001), tempo de latência (20,9 versus 33,6 horas, p = 0,001) e idade gestacional no parto (36,5 versus 37,2 semanas, p = 0,025). Não houve associações significativas entre os grupos e a presença de resultados perinatais adversos. A idade gestacional no diagnóstico foi o único preditor significativo de desfecho composto adverso (x2 [1] = 3,1, p = 0,0001, R2 Nagelkerke = 0,138). Conclusão: Não houve associação entre manejo ativo e expectante em gestantes com PPROM entre 34 e 36 semanas e 6 dias de gestação e resultados perinatais adversos.

Disforia de género en niños y controversias en su tratamiento: dos concepciones distintas sobre la identidad de género / Disforia de gênero em crianças e controvérsias em seu tratamento: duas concepções diferentes sobre a identidade de gênero / Gender Dysphoria in Children and Controversies about its Treatment: Two Different Conceptions of Gender Identity

Resumen La disforia de género es una marcada incongruencia entre el sexo que se siente o expresa y el que se asigna al nacer, asociada a un malestar clínicamente significativo o deterioro en lo social, que puede darse en niños, adolescentes y adultos. En relación con los pacientes pediátricos, no existe actualmente consenso sobre su tratamiento, así como tampoco evidencia que apoye claramente un enfoque por sobre otro. En la literatura se describen principalmente tres tipos de abordaje en niños preadolescentes: modelo terapéutico, watchful waiting (espera atenta) y modelo afirmativo. En este trabajo se realiza una breve revisión de la literatura existente sobre la disforia de género, se describen los distintos abordajes en niños y se analizan las visiones antropológicas que los sustentan. Plantearemos que existen al menos dos modos de entender la identidad de género, lo que ha dado lugar, en gran medida, a las controversias en los tratamientos propuestos. Por ello, resulta de gran importancia comprender los supuestos antropológicos en que se fundamentan estos modelos, ya que a cada uno de ellos subyacen diferentes maneras de entender la relación sexo-género en la persona y, por tanto, el rol de la corporalidad y de la autoconsciencia en la identidad de género.

Abstract Gender dysphoria is a marked mismatch between the sex felt or expressed by an individual and that assigned to them at birth. It is associated with clinically significant discomfort or social impairment and can occur in children, adolescents, and adults. The literature mainly describes three approaches for preadolescents: therapeutic model, watchful waiting, and gender affirmative model. However, there is currently no consensus on its treatment nor any evidence that favors one approach over another. This paper provides a brief review of the existing literature on gender dysphoria, explains various approaches for children, and discusses the anthropological views behind them. We argue that at least two ways of understanding gender identity have given rise to disagreements over the proposed treatments. It is quite important to comprehend the anthropological assumptions on which these models are based since they underlie different conceptions of the person's sex-gender relationship and, therefore, the role of corporality and self-awareness in gender identity.

Resumo A disforia de gênero é uma marcada incongruência entre o sexo que se sente ou expressa e o que é designado ao nascer, associada a um malestar clinicamente significativo ou a uma deterioração no âmbito social, que pode ocorrer em crianças, adolescentes e adultos. Quanto aos pacientes pediátricos, não existe atualmente consenso em seu tratamento nem evidência que apoie com clareza uma abordagem sobre outro. Na literatura, são descritos três tipos de abordagem em crianças pré-adolescentes: modelo terapêutico, watchful waiting (observação vigilante) e modelo afirmativo. Neste trabalho, é realizada uma breve revisão da literatura sobre a disforia de gênero, são descritas as diferentes abordagens em crianças e são analisadas as visões antropológicas que as justificam. É provável que haja, pelo menos, dois modos de entender a identidade gênero, o que abre espaço a controvérsias nos tratamentos propostos. Por isso, é de grande importância compreender os pressupostos antropológicos nos quais esses modelos estão fundamentados, já que a cada um deles subjazem diferentes maneiras de entender a relação sexo-gênero na pessoa e, portanto, o papel da corporeidade e da autoconsciência na identidade de gênero.

Sangrado tardío luego de tratamiento con macroligadura elástica de hemorroides / Late bleeding after hemorrhoid treatment with rubber macroband ligation

Objetivo: Presentar el caso infrecuente de sangrado tardío posterior al tratamiento con macroligadura elástica de hemorroides, tratamiento propuesto por A. Reis Neto. Caso Clínico: Mujer de 26 años con tratamiento de hemorroides con macroligadura elástica. A los 28 días es admitida en urgencia por proctorragia abundante sin signos de shock hipovolémico. Laboratorio: Hematocrito 27%, Hemoglobina 8,9 mg/dl. Se realiza colonoscopia evidenciando la cicatriz de macroligadura con signos de coágulo desprendido sin sangrado activo. Se decide conducta expectante con tratamiento de la hipovolemia incial y anemia. Evoluciona sin resangrado con control endoscópico a los 60 y 180 (sin sangrado y excelentes resultados). Discusión: La macroligadura es una técnica alternativa para el tratamiento de hemorroides con excelentes resultados anatómicos y funcionales. Presenta menor dolor postoperatorio, bajo índice de complicaciones (ninguna severa o propia del método). No existen comunicaciones sobre sangrado tardío grave tanto en ligaduras convencionales como macroligadura. Conclusiones: Se presenta el primer caso comunicado a la fecha de un sangrado tardío en macroligaduras que fue resuelto en forma conservadora.

Objetive: To present an infrequent clinical report of a case of late bleeding after rubber macroband ligation. Case report: A 28-year-old female with severe rectal bleeding but no associated shock was presented 28 days after rubber macroband ligation at emergency room. Blood samples showed acute anemia. An urgent colonoscopy was performed which showed a scar without acute bleeding. Medical treatment was settled. There was no secondary bleeding in follow up. Endoscopic control was done at 60 and 180 days. Discusion: Hemorrhoidal rubber macroband ligation is a modification of conventional rubber band ligation. It was proposed and developed by J.A. Reis Neto (Campinas, SP, Brazil). Morbidity is low and results are excellent. There is no previous report of delayed bleeding considering both rubber band and macroband ligation. Conclusion: The First case of late bleeding after rubber band ligation treated with conservative measures.
