ABSTRACT

Causes of abortion, stillbirth, and perinatal mortality in horses were investigated in the Department of Veterinary Pathology of the Federal University of Rio Grande do Sul (SPV-UFRGS) from 2000 to 2015. In this period, 107 cases were analyzed using macroscopic, microscopic, and complementary tests. Of these, 77 were aborted fetuses, 16 were stillbirths, and 14 were perinatal deaths. Conclusive diagnosis was established in 42.8% of the fetuses analyzed, with 28.6% classified as infectious origin, 9.1% as non-infectious, and 5.1% as other. Bacterial infections, especially those related to Streptococcus spp. were the most frequently observed. In stillborn foals, diagnosis was established in 62.5% of cases, and 50% of these were related to non-infectious causes, such as dystocia and birth traumas. As for perinatal mortality, a conclusive diagnosis was reached in 78.57% of cases, and infectious causes associated with bacterial infections accounted for 64.1% of these diagnoses.(AU)


Causas de aborto, natimortalidade e mortalidade perinatal em equinos foram investigadas no Setor de Patologia Veterinária da Universidade Federal do Rio Grande do Sul (SPV-UFRGS) durante o período de 2000 a 2015. Nesse período, foram analisados 107 casos através de exames macroscópico, microscópico e exames complementares, desses 77 correspondiam a fetos abortados, 16 natimortos e 14 mortes perinatais. Diagnóstico conclusivo foi estabelecido em 42,8% dos fetos analisados e classificados como origem infecciosa em 28,6% dos casos, não infecciosa com 9,1% e outros com 5,1% dos casos. As infecções bacterianas, em especial as relacionadas a Streptococcus spp. foram as mais frequentemente observadas. Em potros natimortos, diagnostico foi estabelecido em 62,5% dos casos, e destes, 50% foram relacionados a causas não infecciosas, como distocia e traumas durante o parto. Quanto a mortalidade perinatal, em 78,57% dos casos houve um diagnostico conclusivo, e as causas infecciosas associadas a infecções bacterianas corresponderam a 64,1% desses diagnósticos.(AU)

ABSTRACT

Abstract Fetal thyroid complications in pregnancy are uncommon, and are commonly related to the passage of substances through the placenta. The excessive iodine intake during the pregnancy is a well-known mechanism of fetal thyroid enlargement or goiter, and invasive procedures have been proposed for the treatment of fetal thyroid pathologies. In the present report, we demonstrate two cases from different centers of prenatal diagnosis of fetal thyroid enlargement and/or goiter in three fetuses (one pair of twins, wherein both fetuses were affected, and one singleton pregnancy). The anamnesis revealed the ingestion of iodine by the patients, prescribed from inadequate vitamin supplementation. In both cases, the cessation of iodine supplement intake resulted in a marked reduction of the volume of the fetal thyroid glands, demonstrating that conservative treatmentmay be an option in those cases. Also, clinicians must be aware that patients may be exposed to harmful dosages or substances during pregnancy.


Resumo As complicações fetais da tireoide na gravidez são incomuns e são comumente relacionadas à passagem de substâncias pela placenta. A ingestão excessiva de iodo durante a gravidez é um mecanismo bem conhecido de aumento da tireoide ou bócio fetal, e procedimentos invasivos foram propostos para o tratamento de patologias da tireoide fetal. No presente relato de caso, demonstramos dois casos de diferentes centros de diagnóstico pré-natal de aumento da tireoide fetal e/ou bócio em três fetos (um par de gêmeos, em que ambos os fetos foram afetados, e uma gravidez única). A anamnese revelou a ingestão de iodo pelos pacientes prescrita por suplementação inadequada de vitaminas. Nos dois casos, a interrupção da ingestão de suplemento de iodo resultou em uma redução acentuada do volume das glândulas tireoides fetais, demonstrando que o tratamento conservador pode ser uma opção nestes casos. Além disso, os médicos devem estar cientes de que as pacientes podem ser expostas a doses ou substâncias nocivas durante a gravidez.

ABSTRACT

OBJECTIVE@#To investigate the application value of whole exome sequencing technology in fetuses with congenital structural abnormalities.@*METHODS@#The chromosomal abnormalities of 1147 families were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in late pregnancy or after birth were reanalyzed. Subgroups were divided according to the organs involved and whether single malformation or not. The gene regulatory network map was drawn by using string database and Cytoscape software. Fisher exact probability method was used to compare the difference of the diagnostic rate of pathogenic genes among the groups.@*RESULTS@#A total of 160 fetal cases received positive molecular diagnosed, involving 178 variant sites of 125 pathogenic genes, including 8 cases (4.9%, 8/163) by data reanalysis, and the overall positive diagnosis rate was 13.9%. Diagnostic rate was highest in the group of skeletal malformation (31.5%, 39/124) and lowest in that with thoracic malformation (0, 0/32). The gene clusters of fetal edema and intrauterine growth restriction were independent, and were not associated with the major structural malformations. The probability of each parent carrying the same recessive gene variant was 0.03 (39/1146) and 0.08 (4/53) with positive family history.@*CONCLUSION@#For fetuses with congenital structural abnormalities that are negative for conventional genetic tests, 13.9% of phenotypic associated pathogenic/likely pathogenic genetic variants can be detected by whole exome sequencing technology. Its application value for prenatal diagnosis varies in fetus with different organs involved. Reanalysis of sequencing data for cases with new phenotypes in late pregnancy or after birth can further improve the molecular diagnosis rate. Further investigations are needed to explore the related genetic mechanisms.

ABSTRACT

Epignathus, is a rare oropharyngeal teratoma arising from the head and neck region. Sporadic cases have been described with associated intracerebral teratoma. Even more infrequent and extraordinary is the circumstance of a teratoma with oropharynx destruction. We describe the case of a fetus with pharyngeal mass that completely destroyed the oral cavity. The histological examination revealed an immature teratoma (G3); only one other G3 case has been described.

ABSTRACT

Abstract Objective To analyze the most frequent referrals for fetal echocardiography, including advanced maternal age and its association with abnormal results. Methods We included all pregnant women referred to perform fetal echocardiography (gestational age 22-32 weeks) in 2 health centers in Rio de Janeiro, from June 2015 to June 2016. Advanced maternal age was considered when age was > 35 years at the time of delivery). Referral reasons and results were recorded, according to the Brazilian Fetal Cardiology Statement. Crude and adjusted prevalence ratios were calculated (Poisson regression). We considered p < 0.05 as significant. Results A total of 1,221 tests were analyzed. Abnormal fetal echocardiography was observed in 14.82% of the cases. The most frequent abnormalities were interventricular septal defect (6.39%), septal hypertrophy (3.35%) and atrioventricular septal defect (1.14%). Routine exams were performed in 559 women, 289 were referred for advanced maternal age and 373 were referred according to the Brazilian FetalCardiology Statement criteria. An obstetric ultrasound suggesting fetal cardiacabnormality, maternal diabetes, increased nuchal translucency, and obstetric ultrasound suggesting a noncardiac abnormality were strongly associated with an abnormal fetal echocardiography. Abnormal results were not more frequent in women with advanced maternal age when compared with the rest of the study group. Conclusions It was observed that routine exams and advancedmaternal age referrals were very frequent. Those exams were not associated to fetal echocardiography abnormalities. In this scenario, when the obstetric ultrasound suggests a fetal cardiac


Resumo Objetivo Analisar as indicações mais frequentes para realização de ecocardiografia fetal, incluindo idade materna avançada, e a associação destas com exames alterados. Métodos Foram incluídas todas as gestantes que realizaram ecocardiografia fetal na idade gestacional entre 22 e 32 semanas, em 2 centros de referência no Rio de Janeiro, no período de junho de 2015 a junho de 2016. Foi considerada idadematerna avançada se no momento do parto a idade materna fosse> 35 anos. As indicações e os resultados dos exames foram registrados, segundo a Diretriz Brasileira de Cardiologia Fetal. Foramcalculadas as razões de prevalência brutas e ajustadas através da regressão de Poisson, considerando-se p < 0,05. Resultados Um total de 1.221 exames foram analisados. A frequência de exame ecocardiográfico alterado foi 14,82%. As alterações mais frequentes foram defeito do septo interventricular (6,39%), hipertrofia septal (3,35%) e defeito do septo atrioventricular (1,14%). Quinhentos e cinquenta e nove exames foram realizados com indicação de rotina, 289 por idade materna avançada e 373 preenchiam critério de acordo com a Diretriz Brasileira de Cardiologia Fetal. O exame ecocardiográfico alterado foi associado ao ultrassom obstétrico sugerindo cardiopatia fetal, ao diabetes materno, à translucência nucal aumentada e ao ultrassom obstétrico sugerindo alteração extracardíaca. Não foi observada maior frequência de exame ecocardiográfico alterado nas gestantes com idade materna avançada, comparado ao restante da amostra. Conclusão Constatou-se elevada frequência de indicações de rotina, e por idade materna avançada isoladamente, que não foram associados a alterações da ecocardiografia fetal. Em nosso meio, quando o ultrassom obstétrico sugere cardiopatia fetal, é muito provável que a ecocardiografia fetal tambémseja anormal. Portanto, o ultrassom obstétrico é um bom método de rastreio pré-natal.

ABSTRACT

RESUMEN Objetivo: hacer una reflexión sobre el bajo desarrollo que hay actualmente en el campo del diagnóstico prenatal de las anomalías genitales. Materiales y métodos: a partir de la tesis de que el desarrollo del diagnóstico antenatal de las anomalías genitales es escaso, se presenta una comparación con el estado actual de otros campos del diagnóstico prenatal, así como con su contrapartida posnatal; se analizan las distintas causas que pueden haber llevado a esta situación, y se reflexiona sobre formas de mejora de la especialidad. Conclusión: en comparación con otras áreas del diagnóstico prenatal, la detección de anomalías genitales tiene un menor nivel de desarrollo en cuanto a la disponibilidad de herramientas diagnósticas, de protocolos de manejo o investigación clínica. Algunas causas probables son la percepción de baja prevalencia, una importancia limitada o las dificultades para su exploración. Una forma de reforzar este componente de la medicina fetal sería la integración del conocimiento actual, la adquisición de herramientas adecuadas, y una traslación a la medicina clínica.


ABSTRACT Objective: To reflect on how the area of genital abnormalities has fallen behind in prenatal diagnosis. Materials and methods: Based on the thesis that prenatal diagnosis of genital abnormalities has scarcely developed, a comparison with other areas of prenatal diagnosis and with its postnatal counterpart is presented; different explanations for this situation are examined; and a reflection is made on ways to improve the specialty. Conclusion: Compared to other disciplines, prenatal diagnosis of genital abnormalities finds itself lagging behind in terms of diagnostic tools, management protocols and scientific literature. Potential causes include a perception of low prevalence and limited importance, or exploration challenges. Integration of current knowledge, together with the acquisition of the appropriate tools and translation to clinical medicine, would be a way to make this discipline stronger.

ABSTRACT

Sirenomelia or mermaid syndrome is an extremely rare congenital lethal malformation with a frequency between 1.5 and 4.2 per 1 000 000 pregnancies.The association of sirenomelia with the VACTERL association is very rare, with twenty cases reported in the literature and only two cases with VACTERL-H. We present two cases of sirenomelia, type I and type II associated with VACTERL-H and VACTERL syndromes and we review the literature. First time pregnancy women aged 15 and 40 years, without harmful habits and diseases, where between 25-27 gestational week (GW) the prenatal study identifies malformative fetus and the pregnancy is interrupted by medical evidence. The fetopathological examination in the first case identified sirenomelia type I associated with myelomeningocele, hydrocephalus, anal imperforation, single umbilical artery, bilateral renal agenesis, ureteral and bladder agenesis, tracheo-esophageal fistule, agenesis of external genitals, monkey fold of the left palm of the hand - VACTERL-H. In the second case, where genetic testing is normal, sirenomelia type II associated with agenesis of external genitalia, anal imperforation, myelomeningocele, dolichocrania, macroglossia, low set ears, left preauricular skin tag, long philtrum, lung hypoplasia, split cadiac apex, single umbilicalis artery, blind end colon, hepatomegaly, accessory spleen, polycystic horseshoe kidney, uterine and vaginal agenesis, presence of two ovaries and duodenal stenosis - VACTERL association. This two cases, lead us to believe that sirenomelia and the VACTERL association are probably different manifestations of a pathogenetic process leading to disorders of blastogenesis at different levels during embryonic development.


La sirenomelia es una malformación congénita y excepcionalmente rara, con una frecuencia entre 1,5 y 4,2 en un millón de embarazos. La combinación de la sirenomelia con el síndrome de VACTERL es igualmente rara. La literatura especializada informa sobre la existencia de una veintena de casos solamente; en lo que respecta a su asociación con el síndrome de VACTERL-H se conocen solo dos casos. Luego de realizar una revisión de la literatura presentamos dos casos de sirenomelia asociada con los síndromes de VACTERL-H y de VACTERL En el estudio se analizaron los primeros embarazos de dos mujeres, edad de 15 y de 40 años, respectivamente, ambas mujeres completamente sanas y sin hábitos viciosos. Entre la vigésima quinta y la vigésima séptima semana gestacional (SG) del embarazo ambas mujeres, el análisis prenatal comprueba la existencia de malformación del feto debido a lo cual los embarazos fueron interrumpidos por prescripción médica. El análisis fetopatológico del primer caso comprueba la existencia de sirenomelia de tipo I asociada con mielomeningocele, hidrocefalia, atresia anal, arteria umbilical única, agenesia bilateral de los riñones y de los ureteres que transportan la orina desde los riñones hasta la vejiga, fístula traqueoesofágica, agenesia de los órganos genitales externos, línea simiesca en la palma de la mano izquierda - VACTERLH. En el segundo caso, en que el análisis genético ha resultado normal, se observó la presencia de sirenomelia de tipo II asociada con agenesia de los órganos genitales externos, atresia anal, mielomeningocele, dolicocrania, macroglosia, orejas bajas, filtrum alargado, hipoplasia pulmonar, ápice cardíaco escindido, arteria umbilical única, colon terminado en ciego, bazo accesorio, poliquistosis renal, riñón en herradura, agenesia vaginal y de útero, presencia de dos ovarios y estenosis duodenal - VACTERL asociación. Los dos casos investigados permiten llegar a la conclusión de que la sirenomelia y su combinación con el síndrome de VACTERL probablemente sean manifestaciones diferentes de un proceso patogenético que conlleva la alteración de la blastogénesis en distintos niveles durante el proceso del desarrollo embrionario.

ABSTRACT

Abstract The Ex Utero Intrapartum Treatment (EXIT) is a surgical procedure performed in cases of expected postpartum fetal airway obstruction, allowing the establishment of patent airway while maintaining placental circulation. Anesthesia for EXIT procedure has several specific features such as adequate uterine relaxation, maintenance of maternal blood pressure fetal anesthesia and fetal airway establishment. The anesthesiologist should be aware of these particularities in order to contribute to a favorable outcome. This is a case report of an EXIT procedure performed on a fetus with a cervical lymphangioma with prenatal evidence of partial obstruction of the trachea and risk of post-delivery airway compromise.


Resumo O procedimento Intraparto Extra-Uterino (EXIT) é procedimento cirúrgico realizado em casos de previsão de obstrução de via aérea fetal no pós-parto, que permite estabelecer via aérea patente enquanto a circulação placentária é mantida. A anestesia para o procedimento EXIT apresenta várias características específicas, tais como relaxamento uterino adequado, manutenção da pressão arterial materna, anestesia fetal e estabelecimento da via aérea fetal. O anestesiologista deve estar ciente dessas especificidades para contribuir para desfecho favorável. Trata-se de relato de caso de procedimento EXIT realizado em feto com linfangioma cervical e evidência pré-natal de obstrução parcial de traqueia e risco de comprometimento de via aérea pós-parto.

ABSTRACT

ABSTRACT BACKGROUND: The prevalence of congenital abnormalities in general populations is approximately 3-5%. One of the most important applications of obstetric ultrasound is in detection of fetal structural defects. OBJECTIVE: To assess fetal structural anomalies diagnosed using ultrasound in the three trimesters of pregnancy. DESIGN AND SETTING: Retrospective cohort study at the Mário Palmério University Hospital of the University of Uberaba (Universidade de Uberaba, UNIUBE), from March 2014 to December 2016. METHODS: Ultrasound data at gestational weeks 11-13 + 6, 20-24 and 32-36 were recorded to identify fetal anomalies in each trimester and in the postnatal period. The primary outcome measurements were sensitivity, specificity, positive predictive value and negative predictive value for detection of fetal anomalies and their prevalence. RESULTS: The prevalence of anomalies detected using ultrasound was 2.95% in the prenatal period and 7.24% in the postnatal period. The fetal anomalies most frequently diagnosed using ultrasound in the three trimesters were genitourinary tract anomalies, with a prevalence of 27.8%. Cardiac anomalies were diagnosed more often in the postnatal period, accounting for 51.0% of all cases. High specificity, negative predictive value and accuracy of ultrasound were observed in all three trimesters of pregnancy. CONCLUSION: Ultrasound is safe and has utility for detecting fetal anomalies that are associated with high rates of morbidity and mortality. However, the low sensitivity of ultrasound for detecting fetal anomalies in unselected populations limits its utility for providing reassurance to examiners and to pregnant women with normal results.

ABSTRACT

RESUMEN INTRODUCCIÓN: La anemia fetal es una importante causa de morbilidad y mortalidad perinatal. En la actualidad la principal herramienta terapéutica es la transfusión fetal intrauterina, permitiendo una mejoría en el pronóstico y sobrevida en fetos con anemia severa. El objetivo de este estudio fue reportar los resultados obtenidos en el Centro de Referencia Perinatal Oriente (CERPO). MÉTODO: Se realizó un análisis descriptivo retrospectivo de los casos de anemia fetal que requirieron transfusión intrauterina en CERPO entre los años 2003-2019. RESULTADOS: Se incluyeron 17 embarazos, con un total de 27 procedimientos. La sobrevida perinatal fue de 82%, con un 18% de mortalidad perinatal. Se reporta una tasa de mortalidad de 3,7% asociado al procedimiento. CONCLUSIÓN: Los resultados observados son similares a lo publicado, con una tasa de complicaciones similar a lo reportado en la literatura internacional y nacional.

ABSTRACT

La enfermedad cardíaca congénita se ha asociado con alteraciones del neurodesarrollo. Niños y adolescentes con cardiopatía congénita presentan déficits en distintos dominios neurológicos (motor, cognitivo, lenguaje, rendimiento escolar y habilidades sociales). Históricamente se atribuyeron a una potencial injuria cerebral durante la cirugía cardíaca. Sin embargo, evidencia actual demuestra que RN de término ya presentan anormalidades cerebrales y retraso de la maduración (dismaduración) con alta prevalencia 28% (IC 95%, 18-40%) Entre ellas se reporta ventriculomegalia, agenesia cuerpo calloso, hipoplasia de vermis, hemorragia intraventricular, aumento espacio subaracnoídeo, alteraciones de la sustancia blanca (Leucomalacia periventricular), desarrollo cortical alterado y quistes periventriculares. El mecanismo más estudiado es la interferencia de la cardiopatía con el shunt fisiológico de derecha a izquierda por el foramen ovale, que asegura la llegada de la sangre mejor oxigenada primeramente al cerebro. Se discute el beneficio de potenciales intervenciones prenatales neuroprotectoras y el diagnóstico temprano de cardiopatías congénitas.


Congenital heart disease has been associated with neurodevelopmental disorders. Children and adolescents with congenital heart disease present deficits in different neurological domains (motor, cognitive, language, school performance and social skills). Historically they were attributed to a potential brain injury during cardiac surgery. However, current evidence shows that term newborns already present brain abnormalities and delay of maturation (dysmaturation) with high prevalence 28% (95% CI, 18-40%) Among them is reported ventriculomegaly, Corpus Callosum agenesis, hypoplastic vermis, intraventricular hemorrhage, subarachnoid space enlargement, white matter alterations (periventricular leukomalacia), altered cortical development and periventricular cysts. The most studied mechanism is the interference of heart disease with the physiological shunt from right to left by the foramen ovale, which ensures the arrival of the best oxygenated blood first to the brain. The benefit of potential neuroprotective prenatal interventions and early diagnosis of congenital heart diseases is discussed.

ABSTRACT

RESUMEN OBJETIVO: el propósito es describir el efecto de los corticoides prenatales en la malformación congénita de la vía aérea pulmonar (MCVAP) mediante la evaluación secuencial del CVR y mostrar la experiencia en nuestro centro de terapia fetal. MATERIALES Y MÉTODOS: serie de casos en la cual se incluyeron ocho pacientes del Hospital de San José; con diagnóstico de MCVAP; se evaluó edad gestacional, el CVR (longitud x largo x ancho, en cms de la masa) x 0.523/circunferencia cefálica) como factor pronóstico, la desviación mediastínica, la presencia de hidrops, el tipo de MCVAP y la localización. Se aplicó betametasona a dosis de inducción de madurez pulmonar fetal. Se realizó la medición del CVR pre y pos tratamiento. Los datos obtenidos fueron analizados mediante el software estadístico SPSS (Versión 11.0 SPSS Inc. Chicago, IL). Se utilizaron la prueba Wilcoxon y el índice de correlación de Spearman según el caso. Un valor de p<0.05 se consideró significativo. RESULTADOS: ocho pacientes fueron incluidas. La mediana de la edad gestacional fue 30.5 semanas. Cuatro casos fueron tipo I, dos tipo II y dos tipo tres. Cuatro casos presentaron desviación mediastinal. Cinco casos fueron derechos y uno bilateral. Ningún caso presentó hidrops. El CVR pre tratamiento fue 0,93(RIQ:0,17-2,1) y pos tratamiento 0,55(RIQ:0,07-1,39). Se encontró una disminución del CVR pos tratamiento en todos los casos (p 0.0117) e índice de correlación de Spearman 0.9524 CONCLUSIÓN: Después de la aplicación de corticoides encontramos una disminución del CVR en todos los casos descritos. El uso de corticoides podría ser parte de la terapia prenatal con miras a mejorar el pronóstico.


ABSTRACT OBJECTIVE: The purpose of this study is to describe the effect of prenatal corticosteroids in the CPAM by sequential evaluation of the CVR, and to show the experience in our fetal therapy center. MATERIALS AND METHODS: Series of cases in which eight patients from the Hospital of San José were included; with diagnosis of CPAM; gestational age was evaluated, CVR (CVR = length x length x width cm, mass) x 0.523 / head circumference) as a prognostic factor, mediastinal shift, hydrops, type of CPAM, location. Betamethasone was applied to fetal lung maturation dose. In all patients underwent CVR measurement pre and post treatment. The data were analyzed using SPSS statistical software (Version 11.0 SPSS Inc. Chicago, IL). The Wilcoxon test and the Spearman correlation index were used according to the case. A value of p <0.05 was considered significant. RESULTS: eight patients were included. The median of gestational age was 30.5 weeks. Four cases were type I, two type II and two type three. Four cases were mediastinal shift. Five cases were rights and one bilateral. No case presented hydrops. The pretreatment CVR was 0,93(RIQ: 0,17-2,1) and post-treatment 0,55(RIQ: 0,07-1,39). We found a decrease in CVR after treatment in all cases (p 0.0117) and Spearman correlation index 0.9524 CONCLUSION: After application of corticosteroids are a reduction in CVR in all the cases described. The use of corticosteroids may be part of prenatal therapy to improve prognosis.

ABSTRACT

Los quistes renales simples son poco frecuentes en recién nacidos, niños y adolescentes. Suelen ser únicos, y ocasionalmente múltiples. No existen evidencias de riesgo familiar. El objetivo de la presentación fue resaltar la importancia del diagnóstico precoz de malformaciones congénitas y/o defectos estructurales del feto, por ultrasonografía, en la atención primaria de salud. Presentamos las imágenes ecográficas de un caso de afectación fetal por un quiste renal simple a las 36 semanas, sin otros hallazgos ultrasonográficos. Previo asesoramiento genético y dado la avanzada edad gestacional y el buen pronòstico con que cursan estos casos además de no tener otro defecto genético asociado, la pareja decidió la continuación del embarazo. El caso fue confirmado por ecografía posnatal(AU)


Simple renal cysts are rare in newborns, children and adolescents. They tend to be unique, and occasionally multiple. There is no evidence of family risk. The objective of the presentation was to highlight the importance of early diagnosis of congenital malformations and / or structural defects of the fetus, by ultrasonography, in primary health care. We present the echography of a case of fetal involvement by a simple renal cyst at 36 weeks, with no other ultrasonography findings. The parents decided to continue the pregnancy previous genetic counseling, given the advanced gestational age and good prognosis with these cases, and considering there is no other genetic defect associated. The case was confirmed by postnatal ultrasound(AU)

ABSTRACT

Objectifs : Evaluer l'apport de l'échographie obstétricale dans le dépistage anténatal des malformations foetales, il s'agit plus spécifiquement de déterminer la prévalence des malformations anténatales à l'échographie, d'identifier les différents types de malformations dépistées, de rechercher les facteurs de risque associés aux malformations observées, d'établir le pronostic vital sur la base de l'échographie anténatale et de confronter les résultats de l'échographie au diagnostic post natal. Matériel et méthodes : Il s'agissait d'une étude transversale descriptive, effectuée de novembre 2017 à janvier 2019 soit 15 mois à l'Hôpital Régional de Ngaoundéré. Elle concernait toutes les femmes ayant présentées une malformation foetale au cours de l'échographie obstétricale réalisée à l'aide d'un échographe de marque GE LOGIQ 7 par voie trans-abdominale ou trans-vaginale, par un médecin radiologue d'au moins dix ans d'expérience. Un interrogatoire et un examen clinique étaient également réalisés chez toutes les femmes retenues. Les variables étudiées étaient : l'âge de la mère, l'âge de la grossesse, les résultats de l'échographie obstétricale et les caractéristiques des malformations dépistées. L'analyse statistique a été faite grâce aux logiciels Sphinx V.5.1.0.7 et Excel 2010. Résultats : Les malformations foetales représentaient 0,62% de toutes les échographies et 1,21% des échographies obstétricales. L'âge moyen des mères était de 26 ans avec des extrêmes de 16 à 45 ans. Les primipares étaient les plus représentées soit 43%, suivies des multipares avec 40% et des pauci pares avec 17%. 70,7% des malformations ont été dépisté au deuxième trimestre, les malformations du système nerveux central occupaient le premier rang (46,34%), suivi des malformations de l'appareil urinaire (19,51%), de la paroi abdominale (14,63%), du squelette (9,76%) et du système digestif (4,88%), l'on a observé une malformation du tissu mou du cou (2,44%) et pulmonaire (2,44%). 94,7% des malformations étaient associées à des affections du liquide amniotique et 5,3% à une tachycardie foetale, 14,63% de grossesses portaient des malformations considérées comme incompatibles avec la vie et 24,39% des foetus malformés étaient décédés in utéro. L'antécédent de malformation dans la fratrie était de 5,7% et la notion de consanguinité était de 28,6%. Le taux de concordance entre le diagnostic anténatal et postnatal était de 95,65%

ABSTRACT

Antecedentes. Las malformaciones congénitas producidas por la diabetes materna constituyen un síndrome conocido como «embriopatía diabética¼. Los defectos se asocian a diabetes pregestacional, tipo 1 ó 2. Su patogénesis no está totalmente esclarecida pero la hiperglicemia parece ser el estímulo intrauterino más importante, favoreciendo producción de radicales libres y otras condiciones adversas para la implantación y desarrollo embrionario/fetal. Descripción del caso. Presentamos caso de gestante multípara, procedente de Tegucigalpa, M.D.C, antecedente de diabetes mellitus tipo 2, hipotiroidismo y obesidad grado I, historia gineco-obstétrica: G:3, C:2, A:1, HV:1, HM:1, 6 controles prenatales, con embarazo de 30.6 SG X FUM. Acude a control prenatal, realizándose ultrasonido obstétrico que mostró raquisquisis con hidrocefalia severa y tendencia al macrocráneo, pie equinovaro bilateral y polihidramnios (ILA 21.7cc). Paciente refirió aproximadamente 10 contracciones esporádicas en 24 hrs. Examen físico: GO: cérvix dilatado 2 cm, B: 50% AP: -3, membranas íntegras, cefálico. Es ingresada con plan de cesárea más OTB obteniendo RN con múltiples malformaciones congénitas (defectos del tubo neural, estructuras craneofaciales, y óseas). Se ingresó a unidad de cuidados intermedios, realizándose USG transfontanelar que reportó hidrocefalia severa y por la presencia de mielomeningocele, se sospechóArnold Chiari tipo II. Se realizó mieloplastía con técnica habitual sin complicaciones, paciente permaneció estable hasta el momento de su egreso hospitalario. Conclusión/recomendación. Niveles de HbA1c en el primer trimestre ≥7% o Glucosa basal >120mg/dl se han asociado al desarrollo de malformaciones. Es importante un estricto control glicémico preconcepcional para disminuir la incidencia de malformaciones asociadas a hiperglicemia en el embarazo...(AU)

ABSTRACT

ABSTRACT Purpose: To assess the need for postnatal evaluation and the medium term outcome in patients with isolated unilateral low grade prenatally detected hydronephrosis. Materials and Methods: We prospectively selected 424 patients (690 kidney units) with a prenatal diagnosis of urinary tract dilatation between 2010 and 2013. We included only those patients with isolated unilateral low-grade hydronephrosis who underwent at least 2 postnatal ultrasound examinations. The Society for Fetal Urology (SFU) grading system was utilized for assessment of the hydronephrosis. We excluded patients with bilateral dilation or other urological abnormalities. The fate of hydronephrosis including resolution, stability or worsening was documented. Results: A total of 66 infants (44 boys and 22 girls) with antenatally diagnosed unilateral urinary tract dilation (23 right and 43 left) were identified. Ultrasounds showed SFU grade 1 hydronephrosis in 32 patients (48%) and SFU grade 2 hydronephrosis in 34 (52%). After a mean follow-up period of 32 months (range 12 to 60), 37 patients (56%) had complete resolution of hydronephrosis while the remaining 29 were stable (44%). None of our patients developed UTIs during follow-up and none required surgical intervention. Conclusions: Prenatally detected, isolated unilateral low-grade hydronephrosis usually have a favorable prognosis. All cases in our cohort showed either stability or resolution of hydronephrosis without any harmful consequences. Based on our findings on medium-term in this category of patients, long-term follow-up is not warranted.

ABSTRACT

Abstract Several changes occur in lipid metabolism during gestation due to hormonal and metabolic changes, which are essential to satisfy the nutritional demands of the maternal-fetal unit development. The gestation shows two distinct periods that begin with fat accumulation, mainly in maternal adipose tissue, and the late phase, characterized by accelerated catabolism, with the increase of fatty acids in the circulation that causes hyperlipidemia, especially the one characterized as hypertriglyceridemia. Maternal hyperlipidemia may be associated with the development of maternal-fetal complications (preterm birth, preeclampsia, vascular complications) and the development of long-term cardiovascular disease. The cardiovascular risk may not only be related to lipoproteins cholesterol content, but also to the number and functionality of circulating lipoprotein particles. This review reports themajor changes that occur in lipoprotein metabolismduring pregnancy and that are associated with the development of dyslipidemias, lipoprotein atherogenic phenotype, and maternal-fetal unit complications.


Resumo Diversas mudanças ocorrem no metabolismo lipídico durante a gestação em função das alterações hormonais e metabólicas, que são essenciais para satisfazer a demanda nutricional ocasionada pelo desenvolvimento da unidade feto-placentária. O período da gestação apresenta dois momentos distintos que iniciam com acúmulo de gordura principalmente no tecido adiposo materno, e a fase tardia, caracterizada por catabolismo acelerado, com aumento de ácidos graxos na circulação causando hiperlipidemia, principalmente a aquela caracterizada como hipertrigliceridemia. A hiperlipidemia materna pode estar associada ao desenvolvimento de complicações materno-fetais (parto prematuro, pré-eclâmpsia, complicações vasculares) e de doenças cardiovasculares, a longo prazo. O risco pode estar relacionado não apenas ao teor de colesterol contido nas frações lipoprotéicas, mas também ao número e a funcionalidade das partículas lipoproteicas. Esta revisão aborda as principais mudanças que ocorrem no metabolismo lipoproteico durante a gravidez, e que estão associadas ao desenvolvimento de dislipidemias, fenótipo aterogênico e complicações maternofetais.
