Hemorragias durante el primer trimestre del embarazo: revisión narrativa / Bleeding in the first trimester of pregnancy, narrative review

Resumen ANTECEDENTES: Las hemorragias durante el primer trimestre del embarazo son un problema que se atiende en la práctica clínica obstétrica diaria. Las conductas de atención suelen estar protocolizadas en casi todas las instituciones; sin embargo, la evidencia científica actual sugiere que algunas de esas conductas no tienen una evidencia sólida que las apoye. OBJETIVO: Revisar la bibliografía reciente y resumir las principales recomendaciones para la atención de casos de hemorragia en el primer trimestre del embarazo. METODOLOGÍA: Estudio retrospectivo basado en la búsqueda bibliográfica de artículos en inglés que contuvieran los términos MeSH: "First Trimester", "Hemorrhage", "Bleeding", "Ectopic Pregnancy" "Abortion", "Incomplete Abortion", "Miscarriage", "Early Pregnancy Loss", "Threatened Abortion" y "Gestational Trophoblastic Disease". Se incluyeron ensayos clínicos controlados, estudios de casos y controles, estudios de cohorte prospectivos y retrospectivos, guías de práctica clínica, protocolos, revisiones sistemáticas y metanálisis incluidos en la base de datos PubMed de 2014 a 2021. RESULTADOS: Se encontraron 54 artículos completos, de los que se descartaron 38 por duplicidad en la información, falta de pertinencia o no actualizados. Al final, solo se incluyeron 16 artículos para la revisión narrativa. CONCLUSIONES: Las hemorragias durante el primer trimestre, si bien son frecuentes no dejan de ser un reto diagnóstico por su amplio espectro de manifestaciones clínicas y causas. Siempre es necesario correlacionar la evaluación clínica completa con los hallazgos ecográficos y las concentraciones de β-hCG y descartar las causas no obstétricas del sangrado, independientemente de la sospecha diagnóstica inicial.

Abstract BACKGROUND: Hemorrhage in the first trimester of pregnancy is a problem seen in daily obstetric clinical practice. Care behaviors are usually protocolized in almost all institutions; however, current scientific evidence suggests that some of these behaviors do not have strong evidence to support them. OBJECTIVE: To review the recent literature and summarize the main recommendations for the care of cases of hemorrhage in the first trimester of pregnancy. METHODOLOGY: Retrospective study based on a literature search of English language articles containing the MeSH terms: "First Trimester", "Hemorrhage", "Bleeding", "Ectopic Pregnancy", "Abortion", "Incomplete Abortion", "Miscarriage", "Early Pregnancy Loss", "Threatened Abortion" and "Gestational Trophoblastic Disease". Controlled clinical trials, case-control studies, prospective and retrospective cohort studies, clinical practice guidelines, protocols, systematic reviews and meta-analyses included in the PubMed database from 2014 to 2021 were included. RESULTS: We found 54 complete articles, of which 38 were discarded due to duplicity in information, lack of relevance or not updated. In the end, only 16 articles were included for narrative review. CONCLUSIONS: First trimester hemorrhage, although frequent, is still a diagnostic challenge due to its wide spectrum of clinical manifestations and causes. It is always necessary to correlate the complete clinical evaluation with ultrasound findings and β-hCG concentrations and to rule out nonobstetric causes of bleeding, regardless of the initial diagnostic suspicion.

Frecuencia de abortos espontáneos en pacientes que acuden al servicio de Gineco-Obstetricia del Hospital de Clínicas

RESUMEN Introducción: El aborto espontáneo, definido como la pérdida del embarazo antes de la viabilidad, es una ocurrencia común. El costo físico y emocional del aborto espontáneo recurrente puede ser alto. Además, aproximadamente solo la mitad de las mujeres que experimentan abortos espontáneos recurrentes descubrirán la causa. Metodología: Es un estudio observacional, descriptivo y temporalmente retrospectivo. El muestreo es no probabilístico de casos consecutivos. La población accesible son mujeres que tuvieron aborto espontáneo y hayan acudido al Hospital de clínicas durante julio de 2019 a julio de 2020. Resultados: Teniendo en cuenta el periodo de estudio entre julio de 2019 y julio de 2020 se registraron 2217 fichas clínicas, en esta investigación se incluyeron 262 mujeres con aborto espontáneo que representa el 11,82 % del total. En cuanto a los factores de riesgo el 98,5 % tiene al menos un factor de riesgo. Discusión: Los factores de riesgo más mencionados en las fichas clínicas fueron Aspiración manual endouterina, Legrado Uterino Instrumental y Cirugía genito urinaria. En la literatura muchos son los factores de riesgo que se menciona, como ser la edad de la paciente, el número anterior de abortos, las infecciones, desequilibrios hormonales, presencia de masas en el útero, incluso se ha estudiado componentes genéticos asociados a este fenómeno.

ABSTRACT Introduction: Spontaneous abortion, defined as the loss of pregnancy before viability, is a common occurrence. The physical and emotional cost of recurrent miscarriage can be high. Furthermore, only about half of women who experience recurrent miscarriages will discover the cause. Methods: It is an observational, descriptive and temporally retrospective study. The sampling is non-probabilistic of consecutive cases. The accessible population are women who had a spontaneous abortion and have attended the Hospital de Clínicas during July 2019 to July 2020. Results: Taking into account the study period between July 2019 and July 2020, 2,217 clinical records were registered, in this The research included 262 women with spontaneous abortion, representing 11.82% of the total. Regarding risk factors, 98.5% have at least one risk factor. Discussion: The most mentioned risk factors in the clinical records were Uterine Manual Aspiration, Instrumental Uterine Curettage, and Genito-urinary Surgery. In the literature there are many risk factors mentioned, such as the age of the patient, the previous number of abortions, infections, hormonal imbalances, the presence of masses in the uterus, even genetic components associated with this phenomenon have been studied.

Manejo conservador de retención de productos de la concepción con anticonceptivos orales combinados / Conservative Management of Retained Products of Conception with Combined Oral Contraceptives. Case Report

Objetivo: presentar el caso de una paciente con retención de productos de la concepción (RPC) después de aborto médico, tratada con anticonceptivos orales combinados (ACOC), y efectuar revisión de la literatura. Caso Clínico: paciente de 37 años, con sangrado genital escaso y leve dolor pélvico, quien tuvo aborto provocado con misoprostol cuatro días antes, acude sin signos de infección, con endometrio mixto de 18,5 mm. Durante seis semanas de seguimiento persiste sangrado y endometrio mixto engrosado, con disminución lenta de la gonadotrofina corionica humana (GCH); se sospecha RPC, se suministra ciclo de ACOC y al terminarlos expulsa completamente el tejido retenido. Metodología: búsqueda bibliográfica en bases de datos Google Scholar, Science Direct, RIMA, PubMed. Revisión de literatura: la RPC se presenta después de parto o aborto (más frecuente). Criterios diagnósticos: sangrado persistente, hallazgos ecográficos y medición de GCH. Diagnóstico diferencial: enfermedad trofoblastica gestacional y malformaciones arteriovenosas uterinas. Es factible el manejo conservador, con bajas tasas de infección o procedimientos quirúrgicos. Ante la evolución prolongada, presencia de signos de infección o hemorragia importante, se impone la evacuación quirúrgica, tradicionalmente con dilatación y legrado, y más recientemente resección histeroscópica. La bibliografía reciente sugiere el uso de ACOC como manejo médico. En nuestro caso, la paciente tomó un ciclo de ACOC y al terminarlos presentó expulsión de los restos retenidos. Conclusiones: el manejo conservador de la RPC con ACOC surge como una opción en casos seleccionados; son necesarios estudios controlados para definir su utilidad..Au

Objective: to report the case of a patient with retained products of conception (RPC) after a medical abortion, successfully treated with combined oral contraceptives (COCs), and to review the literature. Clinical case: a 37-year-old patient, with little genital bleeding and slight pelvic pain, who had had a misoprostol-induced abortion four days before consulting, she attended without signs of infection, with a thikened 18.5 mm mixed endometrium. After six weeks follow-up genital bleeding and thickened mixed endometrium persist, with a slow decrease in human chorionic gonadotropin (HCG), RPC is suspected, and a COC cycle is administered, when finished, she completely expelled the retained tissue. Methodology: Google Scholar, Science Direct, RIMA and PubMed databases were searched. Literature review: RPC occurs after delivery or abortion (more frequent), diagnostic criteria: persistent bleeding, ultrasound findings and HCG measurement; the differential diagnosis includes gestational trophoblastic disease and uterine arteriovenous malformations. Conservative management is feasible, with low rates of infection or surgical procedures, however, in case of prolonged evolution, evident signs of infection or significant bleeding, surgical evacuation is required, traditionally with dilation and curettage, and more recently hysteroscopic resection. Novel bibliography suggests the use of ACOC as medical management. In our case, the patient took a cycle of COC and at the end she expelled the retained remains. Conclusions: conservative management of RPC with COC arises as an option in selected cases, controlled trails are needed to define its usefulness..Au

Toxoplasma gondii induced abortions in a goat herd in Rio de Janeiro, Brazil / Aborto por Toxoplasma gondii em um rebanho de caprinos no estado do Rio de Janeiro, Brasil

ABSTRACT: Although, serological assays for detecting immune response against Toxoplasma gondii in goats and sheep are frequent in Brazil, studies showing lesions and confirmation of infectious causes of abortion in goats in the state of Rio de Janeiro have not been reported. This study aimed to describe an abortion outbreak caused by T. gondii in a goat herd in the state of Rio de Janeiro. At histological examination, necrotizing encephalitis and lymphoplasmacytic myositis were observed in goat fetuses submitted to necropsy. The diagnoses were confirmed by immunohistochemistry, which revealed positive marking structures compatible with T. gondii bradyzoites in the brain and skeletal muscle cysts. T. gondii should be included among the causes of abortion in goats in the Southeast region of Brazil.

RESUMO: Embora sejam frequentes as pesquisas sorológicas da toxoplasmose em caprinos e ovinos no Brasil, os estudos que apresentam as lesões e a confirmação das causas infecciosas de aborto em caprinos no estado do Rio de Janeiro não foram encontrados. Neste trabalho descreve-se Toxoplasma gondii como causa de aborto em uma criação de caprinos no estado do Rio de Janeiro. Ao exame histológico foi observada encefalite necrosante e miosite linfoplasmocítica nos fetos caprinos submetidos à necropsia. A confirmação do diagnóstico foi realizada com o exame de imuno-histoquímica, que revelou marcação positiva de cistos com bradizoítos de T. gondii no encéfalo e em músculo esquelético. T. gondii deve ser incluído entre as causas de aborto em cabras na região sudeste do Brasil.

Genetic analysis of products of conception. Should we abandon classic karyotyping methodology? / Análise genética dos produtos de concepção. Devemos abandonar a metodologia de cariotipagem clássica?

ABSTRACT Objective: To compare the results obtained by the classic and molecular methodology in the analysis of products of conception, the advantages and disadvantages of each method. Methods: Retrospective non-randomized analysis of results obtained from product of conception samples submitted to genetic evaluation, from 2012 to 2017. The evaluations were performed using cytogenetics and/or chromosomal microarray analysis or arrays. Results: Forty samples were analyzed using classic cytogenetics, of which 10% showed no cell growth, 50% had normal results and 40% had abnormalities. Of the 41 cases sent for array analysis it was not possible to obtain results in 7.3%, 39.5% were normal and 60.5% had abnormalities. There was no statistical difference among the results (p=0.89). Most abnormal results were seen till 9 weeks' gestation. The later abnormal miscarriage was seen at 28 weeks' gestation, with karyotype 46,XX,del(15)(q26.2-qter). The results are corroborated by the international literature. Conclusion: Classic cytogenetics and array techniques showed comparable results on the type of alteration observed. Array analysis is preferable to cell culture in delayed abortions, while cytogenetics is more able to show polyploidies. Both have the same growth failure rates when product of conception tissue is not properly collected.

RESUMO Objetivo: Comparar os resultados obtidos pela metodologia clássica e molecular na análise de produtos de concepção, além das vantagens e desvantagens de cada método. Métodos: Análise retrospectiva não randomizada dos resultados obtidos a partir de amostras de produto de concepção submetidas à avaliação genética, de 2012 a 2017. As análises foram realizadas por citogenética clássica e/ou análise cromossômica de microarray ou arrays. Resultados: Quarenta amostras foram analisadas por citogenética, das quais 10% não apresentaram crescimento celular, 50% apresentaram resultados normais, e 40% apresentaram anormalidades. Dos 41 casos encaminhados para análise por array, não foi possível obter resultados em 7,3%, 39,5% eram normais, e 60,5% apresentavam alterações. Não houve diferença estatística entre os resultados (p=0,89). A maioria dos resultados anormais foi observada até a nona semana de gestação. Uma perda fetal mais tardia foi observada na 28ª semana de gestação, com cariótipo 46,XX,del(15)(q26.2-qter). Os números observados corroboraram a literatura mundial. Conclusão: As técnicas de citogenética clássica e análise por array mostraram resultados comparáveis no tipo de alteração observada. O array é preferível à cultura de células em abortos tardios, enquanto a citogenética é mais capaz de mostrar poliploidias. Ambos têm as mesmas taxas de falha de crescimento quando o tecido do produto de concepção não é coletado adequadamente.

Impact of Plasmatic Progesterone on the Day of Frozen Embryo Transfer in Hormone-induced Cycles / Impacto da progesterona plasmática no dia da transferência de embriões congelados em ciclos induzidos por hormônios

Abstract Objective To establish a relationship between serum progesterone values on the day of frozen blastocyst transfer in hormone-replaced cycles with the probability of pregnancy, miscarriage or delivery. Methods This was an ambispective observational study including all frozen-thawed embryo transfer cycles performed at our department following in vitro fecundation from May 2018 to June 2019. The outcomes evaluated were β human chorionic gonadotropin (β-hCG)-positive pregnancy and delivery. Groups were compared according to the level of serum progesterone on the day of embryo transfer: the 1st quartile of progesterone was compared against the other quartiles and then the 2nd and 3rd quartiles against the 4th quartile. Results A total of 140 transfers were included in the analysis: 87 with β-HCG>10 IU/L (62%), of which 50 (36%) delivered and 37 had a miscarriage (42%).Women with lower progesterone levels (< 10.7ng/mL) had a trend toward higher β-HCG-positive (72 versus 59%; p>0.05), lower delivery (26 versus 39%; p>0.05) and higher miscarriage rates (64 versus 33%; p<0.01). Comparing the middle quartiles (P25-50) with those above percentiles 75, the rate of pregnancy was similar (60 versus 57%; p>0.05), although there was a trend toward a higher number of deliveries (43 versus 31%; p>0.05) and a lower number of miscarriages (28 versus 45%; p>0.05). These differences were not statistically significant. Conclusion There were no differences in pregnancy and delivery rates related with the progesterone level when measured in the transfer day. The miscarriage rate was higher in the 1st quartile group.

Resumo Objetivo Avaliar se existe alguma relação entre os valores plasmáticos de progesterona no dia da transferência de um blastocisto desvitrificado em ciclos hormonalmente substituídos e a taxa de gravidez, aborto ou nascido vivo. Métodos Estudo observacional, ambispectivo, incluindo todos os ciclos de transferência de blastocistos congelados no nosso departamento, entre maio de 2018 e junho de 2019. Avaliou-se a taxa de gravidez e de nascidos vivos após 24 semanas de gestação. Os grupos foram comparados de acordo com os valores de progesterona plasmáticos dosados no dia da transferência do blastocisto: comparou-se o 1° quartil com os outros e depois os 2° e 3° quartis com o 4°. Resultados Avaliaram-se 140 transferências: 87 com β gonadotrofina coriônica humana (β-HCG)>10 IU/L (62%), 50 das quais terminaram em nascido vivo (36% do total), enquanto 37 tiveram um aborto (42% das gravidezes). Verificou-se uma tendência para menor número de recém-nascidos nas transferências com níveis de progesterona no 1° quartil (<10.7ng/mL) (26 versus 39%; p>0.05) e ummaior número de abortos (64 versus 33%; p<0.01). Comparando o 2° e 3° quartis com o 4°, verificouse que nos casos em que a progesterona estava acima do percentil 75, apesar de uma taxa de gravidez semelhante (60 versus 57%; p>0.05), houve uma tendência para uma maior taxa de nascidos vivos (43 versus 31%; p>0.05) emenor número de abortos (28 versus 45%; p>0.05) abaixo do percentil 75. Estas diferenças não foram estatisticamente significativas. Conclusão Não se verificaram diferenças estatisticamente significativas para taxa de gravidez e de nascido vivo. A taxa de aborto foi maior no primeiro quartil.

RESUMEN El aborto espontáneo es uno de los más frecuentes de su tipo, con el objetivo de determinar algunos aspectos epidemiológicos del aborto espontáneo y disminuir su incidencia se realizó el presente estudio. A través del método observacional, transversal, descriptivo y prospectivo; se investigaron pacientes atendidas en el Hospital Fe del Valle en el primer semestre del 2019. La muestra estuvo conformada por 109 pacientes con aborto espontáneo, de un universo de 342 remitidas por esta causa. Entre los resultados, se identificó que la edad media es de 27 años. De 88 gestantes, con parto anterior, 40.84% fueron eutócicos, de 111 con abortos anteriores 29.74% fueron espontáneos. La manifestación clínica más frecuente fue el sangrado transvaginal (79.81%). La mayoría de los abortos espontáneos ocurrieron en el primer trimestre del embarazo, la edad gestacional media al momento de ocurrencia del evento fue 9.3 semanas; los factores de riesgo más frecuentes fueron: consumo de café (62.39%), aborto previo (44.04%). El consumo de cafeína, el tabaquismo y el aborto espontáneo precoz son factores de riesgo frecuentes en las pacientes estudiadas.

ABSTRACT Spontaneous abortion is one of the most frequent of its kind. In order to determine some epidemiological aspects of spontaneous abortion and reduce its incidence, the present study was carried out. Through the observational, transversal, descriptive and prospective method; Patients treated at the Hospital Fe del Valle in the first half of 2019 were investigated. The sample consisted of 109 patients with spontaneous abortion, out of a universe of 342 referred for this cause. Among the results, it was identified that the mean age is 27 years. Of 88 pregnant women, with previous delivery, 40.84% ​​were eutocic, of 111 with previous abortions 29.74% were spontaneous. The most frequent clinical manifestation was transvaginal bleeding (79.81%). The majority of spontaneous abortions occurred in the first trimester of pregnancy, the mean gestational age at the time of occurrence of the event was 9.3 weeks; the most frequent risk factors were: coffee consumption (62.39%), previous abortion (44.04%). Caffeine consumption, smoking and early spontaneous abortion are frequent risk factors in the patients studied.

Experiencia clínica del uso de la ficha SIP/CLAP en mujeres con aborto espontáneo resuelto por vía quirúrgica / Clinical experience of the use of the SIP/CLAP form use in women with spontaneous abortion treated by surgical means

INTRODUCCIÓN Y OBJETIVOS: En Chile, existen datos parcializados en cuanto a la prevalencia de aborto. La población migrante ha generado un cambio en las características de las pacientes en situación de aborto. El objetivo es describir las características demográficas y clínicas de las mujeres con aborto de manejo quirúrgico con y sin complicaciones. MÉTODOS: Estudio Descriptivo Transversal. Se incluyeron mujeres atendidas por aborto, sometidas a método de evacuación y que estuvieran ingresadas al sistema SIP/CLAP. Se compararon mujeres con o sin complicaciones con respecto a diferentes características demográficas y clínicas. Se calculó Odd Ratio para algunas variables de interés. RESULTADOS: Se incluyeron 554 mujeres, un 13% (N= 73) tuvo complicación al ingreso, principalmente hemorrágica (40%). Las características demográficas fueron similares en ambos grupos. Hubo mayor riesgo de complicación en mujeres con abortos previos (OR: 2,4 (IC 1,3-4,5), p =0.00), cuando el diagnóstico de ingreso fue aborto incompleto (OR: 85,3 (IC 25,2-288), p=0,00) y cuando se realizó legrado (OR: 4 (IC 2,5-6,5) p=0,00). La mayoría de las pacientes con complicaciones no planeó el embarazo (OR: 11 (IC 3,4-37,7), p=0,00) y no usó método anticonceptivo en esta gestación. El 70% recibió método anticonceptivo al egreso. CONCLUSIONES: Existen características clínicas asociadas a complicación en mujeres con aborto de manejo quirúrgico en nuestro centro, como diagnóstico de ingreso, embarazo no planificado, aborto previo y tipo de evacuación. Existen limitaciones en cuanto a la cantidad y calidad de información, sin embargo, nuestros resultados permiten conocer el perfil de pacientes atendidas por aborto en nuestro centro.

INTRODUCTION AND OBJECTIVES: In Chile, there are partial data regarding the prevalence of abortion. The migrant population has generated a change in the characteristics of patients in an abortion situation. The objective is to describe the demographic and clinical characteristics of women with surgical abortion with and without complications. METHODS: Transversal Descriptive Study. Women treated for abortion, undergoing evacuation method and who were admitted to the SIP / CLAP system were included. Women with or without complications were compared with respect to different demographic and clinical characteristics. Odd Ratio was calculated for some variables of interest. RESULTS: 554 women were included, 13% (N = 73) had complication at admission, mainly hemorrhagic (40%). Demographic characteristics were similar in both groups. There was an increased risk of complication in women with previous abortions (OR: 2.4 (IC 1.3-4.5), p = 0.00), when the diagnosis of admission was incomplete abortion (OR: 85.3 (IC 25.2- 288), p = 0.00) and when curettage was performed (OR: 4 (IC 2.5-6.5) p = 0.00). The majority of patients with complications did not plan pregnancy (OR: 11 (IC 3.4-37.7), p = 0.00) and did not use a contraceptive method in this pregnancy. 70% received contraceptive method upon discharge. CONCLUSIONS: There are clinical characteristics associated with complications in women with surgical management abortion in our center, such as admission diagnosis, unplanned pregnancy, previous abortion and type of evacuation. There are limitations regarding the quantity and quality of information, however, our results allow us to know the profile of patients treated for abortion in our center.

Factors associated with spontaneous abortion: a systematic review / Fatores associados ao aborto espontâneo: uma revisão sistemática

Abstract Objectives: to compile studies produced regardinggenetic and non-genetic risks factors associated with occurrence of spontaneous abortion. Methods: it talks about a systematic review article, with studies between January of 2008 to November of 2018 according to SciELO, PubMed, Lilacs and BVS. Results: in total, 567 articles were found. After applying the definedeligibility criteria, 44 articles made part of the review, being the majority published on Asia between 2008 and 2011, and 10 articles published on Brazil. Not genetic causes like sociodemographic factors and healthy state were among the most associated conditions of spontaneous abortion. Asiatic continent had predominance about the correlation of spontaneous abortion with factors related to life style like obesity, smoking and labor activities, on the other hand, in the Americas, causes related to sociodemographics factors like low pay and low studies are high-lighted. Conclusions: the risk factors change about the occurrence region, being important to make local studies capable of subsidize the implantation of public politics and to reduce abortions.

Resumo Objetivos: compilar estudos produzidos acerca dos fatores de risco genéticos e não genéticos associados a ocorrência de aborto espontâneo. Métodos: trata-se de um artigo de revisão sistemática, com estudos publicados entre janeiro de 2008 a novembro de 2018 nas bases de dados SciELO, PubMed, Lilacs e BVS. Resultados: um total de 567 artigos foram encontrados. Após aplicação dos critérios de elegibilidade definidos, 44 artigos compuseram a presente revisão com a maioria publicada na Ásia, entre os anos de 2008 a 2011, e 10 artigos publicados no Brasil. Causas não genéticas, como fatores sociodemográficos e estado de saúde, estiveram entre as condições mais associadas ao abortamento espontâneo. No continente asiático houve predominância na correlação do aborto espontâneo com fatores relacionados ao estilo de vida como obesidade, tabagismo e atividades laborais; já nas Américas destacam-se causas relacionadas aos fatores sociodemográficos, como baixa renda e baixa escolaridade. Conclusões: os fatores de risco diferem em relação a região de ocorrência, sendo importante a realização de estudos detalhados para que sejam capazes de subsidiar a implantação de políticas públicas e, assim, minorar a ocorrência de abortos.

Zika como causa de aborto espontáneo en zonas endémicas / Zika as a cause of spontaneous abortion in endemic areas

Resumen Introducción: Aunque en la mayoría de los casos la infección por el virus del Zika (ZIKV) causa enfermedad febril sin complicaciones, en mujeres embarazadas es causa reconocida de alteraciones congénitas y muerte fetal. La microcefalia es la característica descrita con mayor frecuencia en el síndrome congénito por este virus. Caso clínico: Paciente de sexo femenino de 23 años de edad que cursaba la novena semana de gestación (SDG) por la fecha de la última menstruación y la 10.3 SDG por ultrasonido. Acudió a los servicios de salud por presentar un cuadro clínico compatible con infección por el ZIKV, la cual se confirmó por estudios de laboratorio. A las 18.6 SDG se documentó feto único sin movimientos, con datos de microcefalia, tórax con área cardiaca sin actividad, placenta corporal anterior con calcificación en el 30% e imagen probable de lago venoso versus quiste placentario. La paciente ingresó en urgencias por aborto diferido. Se indujo el trabajo de parto y se obtuvo por vía vaginal un producto masculino de 80 g, con perímetro cefálico de 9 cm. El análisis del cordón umbilical por la reacción en cadena de la polimerasa con retrotranscriptasa confirmó el diagnóstico de síndrome congénito por ZIKV. Conclusiones: Durante el embarazo debe sospecharse la infección por ZIKV para realizar un diagnóstico oportuno y ofrecer una atención integral. La pérdida del producto de la concepción en estas pacientes se ha documentado, y se ha encontrado ARN del ZIKV en las biopsias de las vellosidades coriónicas, lo que podría sugerir el aborto espontáneo de manera temprana durante la viremia.

Abstract Background: Although in most cases Zika is an uncomplicated febrile disease, in pregnant women is a recognized cause of congenital disorders. Microcephaly is the characteristic most frequently described in the congenital Zika virus syndrome, and the diagnosis requires laboratory confirmation. Case report: A 23-year-old female on the ninth week of pregnancy by date of last menstrual period and 10.3 weeks by ultrasound, attended to Health Services, presenting clinical manifestations of Zika infection, which was later confirmed by laboratory tests. In her 18.6 weeks of pregnancy, a non-mobile single fetus was documented. Additional findings were microcephaly, lack of thorax with cardiac activity, anterior corporal placenta with 30% calcification, and an image of probable venous lake versus placental cyst. She was admitted to the emergency room for late abortion and labor was induced, obtaining an 80 g male product with head circumference of 9 cm. Reverse transcription polymerase chain reaction analysis on the umbilical cord was positive for Zika virus. Conclusions: Zika infection during pregnancy must be suspected and diagnosed promptly to offer comprehensive care. The loss of conception in these patients has been documented with results of chorionic villus biopsies, finding Zika virus RNA and suggesting spontaneous abortion early during viremia.

Factores de riesgo de la enfermedad trofoblástica gestacional: Hospital Central Universitario Dr. Antonio María Pineda / Risk factors of gestational trofoblastic disease: Hospital Central Universitario Dr. Antonio María Pineda

La Enfermedad Trofoblástica Gestacional (ETG) es una patología de la primera mitad del embarazo caracterizada por una degeneración hidrópica de las vellosidades coriales que abarca la placenta y el resto del complejo ovular; es generalmente benigna pero puede malignizarse y distribuirse hacia otros tejidos. Se realizó un estudio descriptivo transversal con recolección retrospectiva de datos cuyo objetivo fue determinar los factores de riesgo de la ETG en pacientes que acudieron al Servicio de Emergencia Gineco-Obstétrica del Hospital Dr. Antonio María Pineda durante el período enero-agosto 2018. Dentro de la muestra se incluyeron las historias clínicas de 55 pacientes siendo la mayor parte mujeres menores de 28 años, de procedencia urbana, multigestas, sin antecedentes de aborto espontáneo o embarazo molar y sin uso de dispositivos intrauterinos o uso prolongado de anticonceptivas orales. En conclusión, se hace necesario un mayor seguimiento a mujeres embarazadas jóvenes con las características anteriormente expuestas con la finalidad de realizar un diagnóstico temprano de la enfermedad y de esta manera implementar medidas que garanticen su salud y vida(AU)

Gestational Trophoblastic Disease (TSG) is a pathology of the first half of pregnancy characterized by a hydropic degeneration of the chorionic villi that spans the placenta and the rest of the ovular complex; it is usually benign, but it can become malignant and spread to other tissues. A descriptive transversal study with retrospective review of medical charts was performed in order to determine the risk factors for TSG of patients evaluated at the Servicio de Emergencia Gineco-Obstétrica of the Hospital Dr. Antonio Maria Pineda during the January-August 2018 period. Fifty-five medical charts were reviewed. Results show that TSG was more common in women < 28 years old that lived in urban areas, which had several pregnancies, with no prior history of spontaneous abortion, molar pregnancy, use of intrauterine devices or prolonged use of contraceptive pills. In conclusion, a follow-up of young pregnant women is necessary in order to have an on time diagnosis of this disease as well as promote measures that guarantee the patients' health as well as her life(AU)

Consensus on the investigation of thrombophilia in women and clinical management / Consenso sobre a investigação de trombofilia em mulheres e manejo clínico

ABSTRACT Objective To standardize the investigation and clinical management of women with laboratory and/or clinical abnormalities suggestive of thrombophilia, in order to optimize antithrombotic approach and indication of laboratory tests. Methodology A discussion was carried out among 107 physicians (gynecologists/obstetricians, hematologists and vascular surgeons) present at a forum held at the Hospital Israelita Albert Einstein, in São Paulo (SP), Brazil. As a minimum criterion, 80% agreement was established in the voting to each recommendation of conduct in the final document. The cases in which there was agreement below 80% were discussed again, reaching a consensual agreement of conduct for the document writing. Conclusion The standardization of an institutional consensus of suggestions of clinical approach contributes to a better management of the group to be evaluated and minimizes risks of intercurrent events. This was the first national consensus on the investigation of thrombophilia in women.

Este foi o primeiro consenso nacional sobre investigação de trombofilia em mulheres.

Live fetus inside the urinary bladder: a case report / Feto vivo dentro da bexiga urinária: relato de caso

ABSTRACT Vesicouterine fistula is a rare condition. Its incidence, however, has been increasing due to the higher incidence of cesarean sections. The presence of a live fetus inside the bladder who passed through a vesicouterine fistula is an extremely rare situation. We report a case of woman who underwent two previous cesarean sections, was referred to a hospital due to mild pelvic pain and genital bleeding. At the moment, physical examination was normal. Ultrasound scan revealed a gestational sac inserted into the anterior wall of the uterus, with a living fetus of approximately 13 weeks, with active body movement and normal heart rate inside it. The fetal abdomen, around the waist, was stuck at the opening of a vesicouterine fistula, so that the fetal head and trunk were entirely into the bladder cavity, while lower limbs remained at the uterine cavity. Laparotomy was performed, the fistulous tract was excised, the fetus (without heart beating) was removed on opening the bladder, and the uterine cavity was emptied. The defects in the bladder and uterus were repaired. The postoperative period was uneventful. A live fetus inside the urinary bladder is a rare condition the continuation of pregnancy is unlikely and the vesicouterine correction can be made by the time of surgical intervention.

RESUMO A fístula vesicouterina é uma condição rara. Sua incidência, no entanto, vem aumentando, devido à maior incidência de cesáreas. A presença de feto vivo dentro da bexiga por meio de uma fístula vesicouterina constutui situação extremamente rara. Relatamos o caso de uma mulher com duas cesarianas anteriores encaminhada para o hospital devido à dor pélvica leve e sangramento genital. Na hospitalização, o exame físico estava normal. A ultrassonografia revelou saco gestacional inserido na parede anterior do útero com feto vivo de aproximadamente 13 semanas, com movimento corporal ativo e frequência cardíaca normal. O abdômen fetal, ao redor da cintura, estava preso na abertura de uma fístula vesicouterina de modo que a cabeça e o tronco fetais estavam totalmente dentro da cavidade da bexiga, enquanto os membros inferiores permaneciam na cavidade uterina. A laparotomia foi realizada, o trajeto fistuloso foi excisado, o feto (que estava sem batimento cardíaco) foi removido ao abrir a bexiga, sendo a cavidade uterina esvaziada. Além disso, foram reparados os defeitos na bexiga e no útero. O pós-operatório transcorreu sem intercorrências. Feto vivo dentro da bexiga é uma condição rara, e a continuidade da gravidez é improvável, sendo que a correção vesicouterina pode ser feita no momento da intervenção cirúrgica.

Chromosomal abnormalities in recurrent miscarriages by conventional karyotyping analysis / Anormalidades cromossômicas em abortos recorrentes por análise de cariótipo convencional

Abstract Objectives: to describe the prevalence and types of chromosomal abnormalities in couples with recurrent miscarriage and products of conception. Methods: electronic searches were performed in the PubMed/Medline database and in the Portal Regional da Biblioteca Virtual em Saúde/BVS (Regional Website of the Virtual Library in Health/BVS) using the descriptors "chromosomal abnormalities and abortions and prevalence". After applying the inclusion and exclusion criterias, 17 studies were selected. Results: 11 studies were conducted in couples with recurrent miscarriage and six in products of conception. The main results of the couples with recurrent miscarriage were: the frequency of chromosomal abnormalities which varied from 1.23% to 12% and there was a predominance alteration of the chromosomal structures (reciprocal translocations, followed by Robertsonian). In products of conception, the results observed were: the frequency of chromosomal abnormality was above 50% in approximately 70% of the studies; there was a predominance alteration of the numerical chromosomal (trisomy - chromosomes 16, 18, 21 and 22, followed by polyploidy and monosomy X). Conclusions: in summary, cytogenetic alterations represent an importante cause of pregnancy loss and its detection can help couples with genetic counseling. Therefore, the value of knowledge on the prevalence of cytogenetic abnormalities in miscarriage samples is unquestionable, once it is permitted a proper genetic counseling for the couple.

Resumo Objetivos: descrever a prevalência e os tipos de anormalidades cromossômicas em casais com aborto recorrente e em produtos de concepção. Métodos: foram realizadas buscas eletrônicas nas bases de dados PubMed/Medline e no Portal Regional da Biblioteca Virtual em Saúde/BVS usando os descritores "chromosomal abnormalities and abortions and prevalence". Após a aplicação de critérios de inclusão e exclusão, 17 estudos foram selecionados. Resultados: 11 estudos foram realizados em casais com aborto recorrente e seis em produtos de concepção. Os principais resultados em casais com aborto recorrente foram: a frequência de anormalidades cromossômicas variou de 1,23% a 12% e houve predomínio de alterações cromossômicas estruturais (translocações recíprocas, seguidas por Robertsonianas). Nos produtos de concepção, os resultados observados foram: a frequência de anormalidade cromossômica foi acima de 50% em aproximadamente 70% dos estudos; houve predomínio de alterações cromossômicas numéricas (trissomia - cromossomos 16, 18, 21 e 22, seguido de poliploidia e monossomia X). Conclusões: em resumo, as alterações citogenéticas representam uma importante causa de perdas gestacionais e sua detecção auxilia no aconselhamento genético do casal. Portanto, o valor do conhecimento sobre a prevalência de anormalidades citogenéticas em amostras de aborto espontâneo é indiscutível, uma vez que permite o aconselhamento genético adequado ao casal.

Fatores de risco para abortamento em um hospital de referência no sul do Brasil: um estudo caso-controle / Risk factors for abortion in a tertiary hospital in south brazil: a case control-study

O estudo teve por objetivo descrever os fatores de risco para o abortamento no Hospital Nossa Senhora da Conceição, Tubarão-SC, no período de julho de 2010 a julho de 2011. Foi realizado um estudo caso-controle, onde foram analisados 366 prontuários, sendo 122 casos de pacientes que deram entrada com abortamento e 244 controles de pacientes que tiveram seus partos normalmente. Foi realizada análise descritiva, bivariada e regressão logística, relatando-se o OR e respectivo IC95%. No presente estudo 96,7% dos abortos foram classificados como espontâneos e 3,3% como provocados. Foi observado que as mulheres que não tinham relação estável apresentaram duas vezes mais chances de abortamento do que as que possuíam (OR: 1,98) (p=0,037), assim como as com menos de oito anos de escolaridade (OR:2,03) (p=0,0013). As pacientes tabagistas apresentaram uma chance de aborto aproximadamente sete vezes maior do que as não fumantes (OR:6,49) (p=0,0000013), e uma magnitude de chance semelhante foi encontrada nas pacientes que não possuíam religião (OR:6,87) (p=0,000013). Foi encontrada também uma associação de aborto com aborto prévio, sendo que as que o possuíam apresentaram o dobro de chance em comparação à aquelas que não possuíam aborto anterior (OR: 1,88) (p=0,021). Mulheres que não possuíam parceiro fixo e religião, assim como aquelas que tiveram oito anos ou menos de escolaridade, fumantes e com história de abortamento prévio apresentaram um risco maior de abortamento na análise multivariada.

The objective of this study was to describe the risk factors for abortion at Hospital Nossa Senhora da Conceição, Tubarão-SC, from July 2010 to July 2011. A case-control study was carried out, which 366 medical records were analyzed, 122 cases of patients who were admitted with abortion and 244 controls of patients who had their normal deliveries. A descriptive, bivariate and logistic regression analysis was performed, reporting the OR and its 95% CI. In the present study, 96.7% of the abortions were classified as spontaneous and 3.3% as provoked. It was observed that women who had no stable relationship were twice as likely to have an abortion as they had (OR: 1.98) (p = 0.037), as well as those with less than eight years of schooling (OR: 2.03) (p = 0.0013). Smoking patients presented a chance of abortion approximately seven times higher than nonsmokers (OR: 6.49) (p = 0.0000013), and a similar magnitude of chance was found in patients who did not have a religion (OR: 6.87) (p = 0.000013). It was also found an association of abortion with previous abortion, and those who had it presented a double chance compared to those who did not have a previous abortion (OR: 1.88) (p = 0.021). Women who did not have a fixed partner and religion, as well as those who had eight years or less of schooling, smokers and previous history of abortion presented a greater risk of abortion in the multivariate analysis.

Perfil De Mulheres Com Perda Gestacional / Profile of womem with gestational loss

A perda gestacional é a complicação mais comum da gestação, definida como a remoção do embrião ou do feto antes de atingir a viabilidade, com idade gestacional menor que 20 semanas ou peso menor que 500 gramas. Dentre as causas mais comuns estão idade materna avançada, alcoolismo, tabagismo, peso materno, aborto espontâneo prévio, fatores genéticos. Os objetivos deste trabalho foram analisar o perfil de pacientes com perda gestacional até 20 semanas e identificar os fatores de risco mais frequentemente associados à perda gestacional. Estudo retrospectivo realizado na Santa Casa de Misericórdia de Passos com aprovação do Comitê de Ética em Pesquisa institucional. Foram analisados em 40 prontuários: idade materna; estado civil; etnia; profissão; grau de escolaridade; moradia; Índice de Massa Corporal; idade gestacional. Os resultados foram 62,5% maiores de 30 anos, deste total 60% acima de 35 anos; 55% casadas, 47,5% brancas e 92,5% moravam na zona urbana. Trinta por cento do lar; 75% não apresentavam curso superior. A maioria das perdas gestacionais ocorreram no primeiro trimestre, 60% menor que 12 semanas e dessas 47,5% entre 8 e 12 semanas. Sessenta por cento apresentavam gestação anterior e 82,5% teve a primeira perda gestacional. Setenta por cento não apresentavam doenças prévias e 95% não havia história de malformação fetal. Constata-se que o perfil das mulheres com perda gestacional são idade acima de 30 anos, perdas principalmente entre 8 e 12 semanas, maioria não tem curso superior, mora na zona urbana, tem gestação anterior, mas é a primeira perda gestacional. (AU)

Gestational loss is the most common complication of gestation, defined as the removal of the embryo or fetus before it reaches viability, with gestational age less than 20 weeks or weight less than 500 grams. Among the most common causes are advanced maternal age, alcoholism, smoking, maternal weight, previous spontaneous abortion, genetic factors. The objectives of this study were to analyze the profile of patients with gestational loss up to 20 weeks and to identify the risk factors most frequently associated with gestational loss. Retrospective study carried out at Santa Casa de Misericórdia de Passos with the approval of the Institutional Research Ethics Committee. We analyzed 40 charts: maternal age; marital status; Ethnicity; profession; Degree of schooling; home; Body mass index; Gestational age. The results were 62.5% greater than 30 years, of this total 60% above 35 years; 55% married, 47.5% white and 92.5% lived in the urban area. Thirty percent of the household; 75% did not have a college degree. The majority of gestational losses occurred in the first trimester, 60% less than 12 weeks, and 47.5% between 8 and 12 weeks. Sixty percent had previous gestation and 82.5% had the first gestational loss. Seventy percent had no prior disease and 95% had no history of fetal malformation. It can be observed that the profile of women with gestational loss is older than 30 years, losses mainly between 8 and 12 weeks, most do not have a college degree, urban area, previous gestation, but it is the first gestational loss.

Medical Termination of Delayed Miscarriage: Four-Year Experience with an Outpatient Protocol / Terminação médica de gravidez inviável do 1° trimestre: quatro anos de experiência com um protocolo de tratamento em ambulatório

Abstract Purpose To evaluate the efficacy of an outpatient protocol with vaginal misoprostol to treat delayed miscarriage. Methods Retrospective analysis of prospectively collected data on women medically treated for missed abortion with an outpatient protocol. The inclusion criteria were: ultrasound-based diagnosis of missed abortion with less than 10 weeks; no heavy bleeding, infection, inflammatory bowel disease ormisoprostol allergy; nomore than 2 previous spontaneous abortions; the preference of the patient regarding the medical management. The protocol consisted of: 1) a single dose of 800 μg of misoprostol administered intravaginally at the emergency department, after which the patients were discharged home; 2) clinical and ultrasonographic evaluation 48 hours later - if the intrauterine gestational sac was still present, the application of 800 μg of vaginal misoprostol was repeated, and the patients were discharged home; 3) clinical and ultrasonography evaluation 7 days after the initiation of the protocol - if the intrauterine gestational sac was still present, surgical management was proposed. The protocol was introduced in January 2012. Every woman received oral analgesia and written general recommendations. We also gave them a paper form to be presented and filled out at each evaluation. Results Complete miscarriage with misoprostol occurred in 340 women (90.2%). Surgery was performed in 37 (9.8%) patients, representing the global failure rate of the protocol. Miscarriage was completed after the first misoprostol administration in 208 (55.2%) women, with a success rate after the second administration of 78.1% (132/169). The average age of the women with complete resolution using misoprostol was superior to the average age of those who required surgery (33.99 years versus 31.74 years; p = 0.031). Based on the ultrasonographic findings in the first evaluation, the women diagnosed with fetal loss achieved greater success rates compared with those diagnosed with empty sac (p = 0.049). Conclusions We conclude this is an effective and safe option in the majority of delayed miscarriage cases during the first trimester, reducing surgical procedures and their consequences.

Resumo Objetivo Avaliar a eficácia de um protocolo de tratamento médico da gravidez inviável do primeiro trimestre (GI1°T) com misoprostol vaginal em regime de ambulatório. Métodos Análise retrospectiva de dados colhidos prospectivamente de grávidas tratadas com misoprostol vaginal em ambulatório. Os critérios de inclusão foram: diagnóstico de GI1°T com < 10 semanas de gestação; ausência de hemorragia abundante, infeção, doença inflamatória intestinal ou alergia ao misoprostol; 2 abortamentos anteriores; e preferência da paciente por tratamento médico. O protocolo consiste em: dia 0-aplicação demisoprostol intravaginal (800μg) no Serviço de Urgência e alta para o domicílio; dia 2-se persistência de saco gestacional intrauterino, aplicação de segunda dose de misoprostol (800μg) e alta; Dia 7-se persistência de saco gestacional intrauterino, proposto esvaziamento uterino instrumentado. O protocolo foi implementado em janeiro de 2012. Todas as grávidas receberam analgesia oral e informação por escrito com recomendações gerais. Receberam ainda um formulário a ser preenchido em cada vinda à urgência. Resultados Das 377 mulheres incluídas, observou-se abortamento completo em 340 (90,2%). As restantes 37 (9,8%) necessitaram de tratamento cirúrgico - taxa de falência global do protocolo. Em 208 (55,2%), o sucesso foi observado ao fim da 1ª dose, com uma taxa de eficácia da 2ª dose de 78,1% (132/169). A idade média das mulheres com sucesso do tratamento médico foi superior à das mulheres sem sucesso do mesmo (33,99 versus 31,74 anos; p = 0,031). O sucesso do tratamento foi maior quando o diagnóstico ecográfico inicial era de um embrião sem vitalidade comparado com os casos de ovo anembrionado (p = 0.049). Conclusões Conclui-se que esta é uma opção de tratamento eficaz e segura na maioria das situações de GI1°T, evitando a necessidade de internamento e de intervenção cirúrgica.

Niveles de tirotrofina y anticuerpos antitiroperoxidasa en el primer trimestre de gestación asociados a complicaciones del embarazo en la mujer eutiroidea / Thyrotropin levels and anti-thyroid peroxidase antibodies during first trimester of pregnancy associated with maternal and foetal complications in euthyroid women

Introducción: El embarazo es una situación fisiológica que presenta cambios endócrinos e inmunológicos. La tiroides modifica su economía para proveer suficientes hormonas a la madre y al feto. La autoinmunidad y las disfunciones tiroideas tienen alta prevalencia en mujeres en edad fértil y pueden afectar el curso de la gestación, con repercusiones clínicas adversas maternas y fetales. El objetivo de este estudio fue relacionar la proporción de gestantes eutiroideas con tirotrofina (TSH) en 2 niveles del rango de referencia ( ± DS; 1,57 ± 0,82 vs. 1,16 ± 0,54 mUI/l, p = 0,001). Los niveles séricos de T4L y T4 fueron similares en ambos grupos. De la subpoblación EP, el 63% fue incluida en EP1 y el 37% en EP2, y en EN el 80% en EN1 y el 20% en EN2. Se observó un incremento significativo (p = 0,001) en las complicaciones en EP (22%) vs. EN (10%). En mujeres EP con y sin aborto espontáneo, la TSH ( ± DS) fue 1,65 ± 0,67 vs. 0,99± 0,77 mUI/l (p = 0, 014). Las mujeres EP con y sin parto prematuro presentaron niveles de TSH (X ± DS) 1,63 ± 0,70 vs. 1,15 ± 0,53 mUI/l (p = 0,012). En el grupo EN, el nivel de TSH ( ± DS) para las mujeres con y sin aborto fue 1,45 ± 0,61 vs. 0,85± 0,66 mUI/l (p = 0,001), mientras que en mujeres con y sin parto prematuro la TSH ( ± DS) fue 1,59 ± 0,71 vs. 0,83 ± 0,64 mUI/l (p = 0,001), respectivamente. Sin embargo, no hubo diferencias entre los niveles promedio de TSH encontrados en aborto vs. parto pretérmino en ambos grupos. En EP, 32 mujeres y 19 en EN desarrollaron hipotiroidismo en el curso del embarazo (ns) y 29 en EP y 10 en EN tiroiditis posparto (p = 0,005). La autoinmunidad tiroidea y los mayores niveles de TSH dentro del rango de referencia en mujeres en primer trimestre de embarazo estarían asociados a complicaciones en el transcurso de la gestación y desarrollo de disfunción tiroidea posparto.

Introduction: Pregnancy is a physiological state presenting with endocrine and immunological changes. The thyroid gland modifies its output in order to provide enough hormonesto the mother and foetus. Thyroid autoimmunity and thyroid dysfunction are prevalent in women of childbearing age and may affect the course of gestation and having maternal and foetal clinical consequences. The purpose of the present study was to establish the relationship between euthyroid pregnant women with thyrotropin (TSH) at two levels of the reference range ( ± SD; 1.57 ± 0.82 vs 1.16 ± 0.54 mIU/L, P=.01). FT4 and T4 values were similar in both groups. Out of the pregnant women in the EP group, 63% were included in EP1, and 37% in EP2. In the EN group, 80% of women were included in EN1 and 20% in EN2. A significant (P=.001) increase in pregnancy complications in EP group (22%) vs EN (10%) was observed. In the EP group, TSH levels were: 1.65 ± 0.67 vs 0.99± 0.77 ( ± SD) mIU/L (P=.014) respectively, in women with and without miscarriage. TSH levels were 1.63 ± 0.70 vs 1.15 ± 0.53 ( ± SD) mIU/L (P=.012), respectively, in women with and without preterm delivery. In the EN group TSH levels were: 1.45 ± 0.61 vs 0.85± 0.66 ( ± SD) mIU/L (P=.001), respectively, in women with and without miscarriage. TSH levels were 1.59 ± 0.71 vs 0.83 ± 0.64 ( ± SD) mIU/L (P=.001), respectively, in women with and without preterm delivery. However, TSH levels in miscarriage and preterm delivery were similar. Thirty-two EP, and 19 EN women developed hypothyroidism in pregnancy (ns), and 29 EP and 10 EN women developed post-partum thyroiditis (P=.005). Conclusion: Thyroid autoimmunity and higher TSH levels within the reference range during the first trimester of pregnancy were associated with pregnancy complications and with the development of thyroid postpartum dysfunction.

Frequency of Chromosomal Abnormalities in Products of Conception / Frequência de anomalias cromossômicas em material de aborto

Abstract Purpose To describe the frequencies of chromosomal abnormalities found in abortion material, and to observe its correlation to maternal age. Methods A retrospective study was conducted based on data obtained from the databank of a medical genetics laboratory in Belo Horizonte, MG, Brazil. A total of 884 results from products of conception analysis were included, 204 of which were analyzed by cytogenetics, and 680bymolecular biology basedon quantitative fluorescence polymerase chain reaction (QF-PCR). The frequency of individual chromosomal aberrations and the relationship between the presence of anomalies and maternal age were also evaluated. Results The conventional cytogenetics technique was able to detect 52% of normal and 48% of abnormal results in the analyzed material. Quantitative fluorescence polymerase chain reaction revealed 60% of normal and 40% of abnormal results from the samples evaluated by this method. The presence of trisomy 15 was detected only by cytogenetics, as it was not included in the QF-PCR routine investigation in the laboratory. A significant increase in abnormal results was observed among women aged 35 years or older compared with younger women (p = 0.02). Conclusion Chromosomal aberrations are still a major cause of spontaneous abortion, and the conventional cytogenetics technique is efficient for miscarriage material analysis, but molecular methods such as QF-PCR are adequate complementary strategies to detect the major chromosomal anomalies, leading to technical reports with reliable results.

Resumo Objetivos Descrever a frequência de anomalias cromossômicas encontradas em material de aborto, e observar se estas estão relacionadas com a idade materna. Métodos Foi realizado um estudo retrospectivo no banco de dados de um laboratório de genética médica em Belo Horizonte, MG. O estudo incluiu 204 resultados avaliados por citogenética, e 680 resultados por biologia molecular baseada em reação em ensaio fluorescente da reação em cadeia da polimerase (QF-PCR), totalizando um número de 884 análises. A frequência de diferentes anomalias cromossômicas e a relação entre a presença de anomalias e a idade materna também foi avaliada. Resultados A citogenética convencional foi capaz de detectar 52% de resultados normais e 48% de resultados anormais no material analisado. A QF-PCR revelou 60% de resultados normais e 40% de anormais nas amostras avaliadas por esta técnica. A presença da trissomia 15 foi detectada por citogenética,mas até então não era incluída na investigação por QF-PCR no laboratório. Umaumento significativo na quantidade de resultados anormais foi observado em mulheres comidade de 35 anos ou mais, quando comparado a mulheres mais jovens (p = 0,02). Conclusão As aberrações cromossômicas são causas importantes de abortos espontâneos, e o estudo citogenético é eficaz para a análise das amostras de material de aborto, mas as técnicas moleculares, como a QF-PCR, representam métodos complementares adequados para detectar as principais anomalias cromossômicas, possibilitando a liberação de laudos com resultados confiáveis.
