Comunicação do Diagnóstico da Síndrome de Down: Experiências de Mães e Médicos / Communication of Down Syndrome Diagnosis: Experiences of Mothers and Doctors / Comunicación del Diagnóstico del Síndrome de Down: Experiencias de Madres y Médicos

O estudo teve como objetivo conhecer as experiências de mães e médicos em relação ao comunicado do diagnóstico da síndrome de Down (SD). Trata-se de uma pesquisa exploratória e transversal, com delineamento qualitativo. Participaram 9 mães e 7 médicos. Foram realizadas 16 entrevistas semiestruturadas individuais. Os dados foram transcritos e submetidos à análise de conteúdo temática. Constatou-se que, para mães e médicos, é uma experiência complexa e difícil, permeada por sentimentos ambivalentes. Nas mães, predominam a tristeza, medo e angústia. A maioria delas sentiram-se insatisfeitas na maneira como receberam o diagnóstico, isso foi atribuído por elas e pelos médicos à falta de preparo durante a formação profissional. Conclui-se que algumas sugestões podem nortear a comunicação do diagnóstico, no intuito de favorecer a elaboração do mesmo, a saber: respeitar o tempo para a mãe observar e conhecer o bebê antes de receber o diagnóstico, comunicar a mãe com sensibilidade e empatia, preferencialmente na presença do outro genitor e de um psicólogo, procurar dar ênfase aos aspectos positivos da saúde do bebê.

The study aimed to know the experiences of mothers and doctors in relation to the statement of the Down syndrome (DS) diagnosis. This is a exploratory and transversal research, with a qualitative design. 9 mothers and 7 doctors participated. 16 individual semi-structured interviews were carried out. The data were transcribed and submitted to thematic content analysis. It was found that for mothers and doctors, it is a complex and difficult experience, permeated by ambivalent feelings. In mothers, sadness, fear and anguish predominate. Most of them felt dissatisfied in the way as they received the diagnosis, this was attributed by them and the doctors to the lack of preparation during vocational training. It is concluded that, some suggestions can guide the communication of the diagnosis, in order to favor its elaboration, namely: respect the time for the mother to observe and get to know the baby before receiving the diagnosis, communicate it to the mother with sensitivity and empathy, preferably in the presence of the other parent and a psychologist, try to emphasize the positive aspects of the baby's health.

Impacto do diagnóstico de Síndrome de Down na perspectiva materna / Impact of the diagnosis of down syndrome in the maternal perspective / Impacto del diagnóstico del síndrome de down desde la perspectiva materna

Objetivo: compreender as percepções maternas acerca do diagnóstico de Síndrome de Down (SD) de seus filhos quando crianças. Método: estudo exploratório-descritivo com abordagem qualitativa realizado com 9 mães de crianças com SD em um hospital público de nível terciário no município de São Paulo. A coleta dos dados ocorreu por meio de entrevistas individuais e semiestruturadas, guiadas por roteiro de tópicos. Os dados foram analisados por meio da análise temática de conteúdo e à luz dos princípios de ancoragem e objetivação da Teoria das Representações Sociais. Resultados: Os dados foram analisados e emergiram duas categorias principais: 1) as percepções maternas em relação à comunicação do diagnóstico de SD do filho; e 2) as percepções maternas acerca do impacto do diagnóstico de SD do filho, com subcategorias interligadas. Conclusão: constatou-se manejo predominantemente inadequado dos profissionais ao comunicarem o diagnóstico de SD, o que potencializou as reações emocionais de sofrimento, que não se restringiram ao momento da notícia. As reações podem ser amenizadas ou potencializadas com a vivência da maternagem e com interações familiares, sociais e com profissionais de saúde.(AU)

Objective: to understand maternal perceptions about the diagnosis of Down Syndrome (DS) of their children as children. Method: Exploratory-descriptive study with a qualitative approach carried out with 9 mothers of children with DS in a tertiary public hospital in the city of São Paulo. Data collection took place through individual and semi-structured interviews, guided by a script of topics. Data were analyzed using thematic content analysis and considering the principles of anchoring and objectification of the Theory of Social Representations. Results: data were analyzed, and two main categories emerged: 1) maternal perceptions regarding communication of the child's DS diagnosis; and 2) maternal perceptions about the impact of the child's DS diagnosis, with interconnected subcategories. Conclusion: There was predominantly inadequate management by professionals when communicating the diagnosis of DS, which potentiated the emotional reactions of suffering, which were not restricted to the moment of the news. Reactions can be mitigated or enhanced with the experience of motherhood and with family and social interactions and with health professionals.(AU)

Las reacciones se pueden mitigar o mejorar con la experiencia de la maternidad, las interacciones con los miembros de la familia, los profesionales de la salud y sociales.(AU)

Diagnóstico tardío de atrofia muscular espinal en paciente con síndrome de Down / Late diagnosis of spinal muscular atrophy in a patient with Down syndrome

El síndrome de Down (SD) es la anomalía cromosómica más frecuente entre los recién nacidos vivos. La atrofia muscular espinal (AME), por su parte, es una enfermedad neuromuscular caracterizada por la degeneración progresiva de las motoneuronas del asta anterior de la médula espinal que produce atrofia muscular, debilidad y parálisis. Presentamos el caso de una niña de 6 años con síndrome de Down derivada a nuestro centro para estudio por cuadro de debilidad muscular generalizada de evolución crónica con falta de adquisición de la marcha. Realizamos una revisión bibliográfica enfocándonos en el compromiso neurológico esperable en el síndrome de Down, la evolución de los hitos del desarrollo motor grueso estipulado para este grupo de pacientes y en los hallazgos que deben sugerir la presencia de una enfermedad neuromuscular.

A case of a 6-year-old girl with Down's syndrome is presented. She was referred to our center due to a history of generalized muscle weakness of chronic evolution, associated to her inability to walk. Her mother claimed that the girl's muscle weakness always called her attention as well as the difficulties to the development of motor skills shown by her daughter compared to other children, whether they were healthy or with Down's syndrome. There was information in her medical record and physical exam that strongly suggested the possibility of suffering a neuromuscular disorder. We asked for a molecular study that confirmed the spinal muscular atrophy diagnosis. We carried out a bibliographical revision focusing on the expected neurological impairment in Down's syndrome, the retardation of the gross motor skills development determined for this kind of patients and on the findings that must suggest a neuromuscular disorder.

Turner syndrome associated with Down syndrome: about a case / Síndrome Turner asociado a síndrome Down: a propósito de un caso

The coexistence of double aneuploidy of Down and Turner syndromes is rare; most cases have been due to double mitotic errors. The objective of the study was to report a case with monosomy of the X chromosome and trisomy of chromosome 21, in mosaic variety, highlighting the phenotypic effect that the presence of different chromosomal abnormalities can produce and compare with those reported in the literature. A 10-year-old Ecuadorian female, born to a multipregnant mother with 46 years at conception, is seen in consultation with a predominant clinical phenotype of Down syndrome, associated with menarche, presence of pubic and axillary villu, where a karyotype is verified 45 X[7]/47XX+ 21 [3]/46, X, der (X)(: p11.1-> q11.1)[1]/46,XX [1]. The present case is a double Turner-Down aneuploidy, with predominantly X monosomy cell line, who shows important mental retardation and some signs of puberal development not usually in Turner syndrome. These features highlight the clinical importance of doing a karyotype in mental retardation cases and searching low mosaics of another aneuploidies in atypical cases. Its complex chromosomal formula and support with molecular cytogenetics allowed diagnostic confirmation and genetic counseling.

La coexistencia de doble aneuploidía de los síndromes de Down y Turner es rara; la mayoría de los casos se han debido a dobles errores mitóticos. Reportar un caso con trisomía del cromosoma 21 y monosomía del cromosoma en X, en variedad mosaico, que curiosamente presenta un despertar puberal precoz y comparar con los reportados en la literatura. Paciente ecuatoriana de sexo femenino, de 10 años de edad, nacida de madre multigesta con 46 años a la concepción, que es vista en consulta con fenotipo clínico predominante de Síndrome Down, asociado a menarquia y telarquia, donde se constata un cariotipo. El presente caso es el primero informado de mosaicismo de doble aneuploidía de Turner-Down asociado con un despertar puberal precoz. Su fórmula cromosómica compleja y el apoyo con la citogenética molecular permitió la confirmación diagnostica y la asesoría genética.

Trastornos mieloproliferativos y leucemia en síndrome de Down. Presentación de dos casos clínicos en el período neonatal / Myeloproliferative disorders and leukemia related to Down syndrome. Report of two clinical cases in neonatal period

ElsíndromedeDownpredisponeatrastornosmieloproliferativos. Se estima que del 5 % al 30 % de los neonatos con esta condición desarrollarán mielopoyesis anormal transitoria. El tratamiento no está estandarizado; la exanguinotransfusión y la citarabina podrían ser efectivos. Se describen dos casos de pacientes con síndrome de Down, quienes durante el período neonatal presentaron leucemia mieloide aguda y mielopoyesis anormal transitoria, los tratamientos utilizados y sus desenlaces. Se considera que la sospecha y el diagnóstico temprano de esta entidad son factores determinantes en el pronóstico.

Down syndrome predisposes to haematological disorders. It is estimated that 5-30% of neonates with this condition will develop transient abnormal myelopoiesis. Treatment is not standardized; exchange transfusion and the use of cytarabine could be effective. We present two clinical cases of patients with Down syndrome, who during the neonatal period showed acute myeloid leukemia and transient abnormal myelopoiesis, the treatments used and their outcomes. Suspicion and early diagnosis of this entity are considered determining factors in prognosis.

Falsos positivos del cribado de trisomía 21 y 18 del primer trimestre y complicaciones obstétricas / Adverse outcomes in pregnancies with false positive trisomy 21 and 18 screening results

OBJETIVO: Analizar si los casos positivos de cribado combinado de trisomía 21 (t21) o trisomía 18 (t18) en ausencia de aneuploidía (falsos positivos- FP) se relacionan con complicaciones de la gestación, ajustando por factores demográficos y clínicos de riesgo. MATERIAL Y MÉTODOS: Estudio retrospectivo de casos y controles anidado en una cohorte de pacientes que acudieron para cribado del primer trimestre. Los casos fueron las pacientes con FP de riesgo combinado de t21 superior a 1/270 o riesgo de t18 superior a 1/100. Se consideraron complicaciones de la gestación: óbito fetal, parto prematuro menor de 34 semanas o prematuro menor de 37 semanas, preeclampsia, retrasos de crecimiento, pequeño para la edad gestacional (CIR, PEG) y diabetes gestacional (DG). Se ajustó por obesidad, edad, paridad, tabaquismo, y técnicas de reproducción asistida. RESULTADO: Se obtuvieron 204 casos de FP, 149 FP para trisomía 21, 41 para trisomía 18, y 14 FP para ambos riesgos. Se encontró asociación estadísticamente significativa de FP t21 con óbito fetal (OR=3,5; ic95% 1,4-8,7; p=0,01), parto prematuro menor de 37 semanas (OR=2,2; IC95% 1,4-3,4; p=0,001), preeclampsia (OR =2,6; IC95% 1,17-6,1; p=0,02), PEG (OR =2,2; IC95% 1,2-4,1; p=0,02), CIR (OR=2,8; IC95% 1,6-5,1; p=0,001), y DG (OR=2,1; IC95% 1,2-3,7; p=0,01). Los FP t18 se asociaron con óbito (OR=8,9; IC95% 2,9-27; p=0,002). CONCLUSIÓN: Los FP del cribado del primer trimestre, para trisomía 21 y trisomía 18, se asocian con resultados obstétricos adversos.

We have studied whether positive cases of combined trisomy 21 (t21) or 18 (t18) screening in the absence of aneuploidy (false positives -FP-) are related to pregnancy complications adjusting for demographic and clinical risk factors. METHODS: Retrospective case-control study nested in a cohort of patients who came for first trimester aneuploidy screening. The cases were patients with FP combined risk of t21 (greater than 1/270) or t18 risk (greater than 1/100). The control group was a sample of patients with low-risk screening. We considered pregnancy complications: stillbirth, premature delivery before 34 and 37 weeks, preeclampsia, growth retardation, small for gestational age (FGR, SGA), and gestational diabetes (GD). Or were adjusted for obesity, age, parity, smoking, and assisted reproduction techniques. RESULTS: 204 cases of FP were obtained, 149 FP for trisomy 21, 41 for trisomy 18, and 14 FP for both risks. A statistically significant association between t21 FP was found with stillbirth (OR = 3.5; 95% CI 1.4-8.7; p = 0.01), preterm delivery less than 37 weeks (OR = 2.2; 95% CI 1.4-3.4; p = 0.001), preeclampsia (OR = 2.6; 95% CI 1.17-6.1; p = 0.02), SGA (OR = 2.2; 95% CI 1, 2-4.1; p = 0.02), FGR (OR = 2.8; 95% CI 1.6-5.1; p = 0.001), and GD (OR = 2.1; 95% CI 1.2 −3.7; p = 0.01). FP t18s were associated with fetal loss (OR= 8.9 (95% CI 2.9-27) p = 0.002. CONCLUSION: FP from first trimester screening for t21 and t18 are associated with adverse obstetric outcomes.

Anomalías congénitas y comorbilidad en neonatos con Síndrome de Down / Congenital anomalies and comorbidities in neonates with Down Syndrome

INTRODUCCIÓN: El Síndrome de Down se presenta en 2,5 de 1.000 recién nacidos vivos chilenos. Presentan más anomalías congénitas y comorbilidades que la población general, aumentando su tasa de hospitalización. OBJETIVO: Describir las anomalías congénitas y comorbilidades de neonatos con Síndrome de Down nacidos y/u hospitalizados en la década 2008-2018. PACIENTES Y MÉTODO: Retrospectiva mente se revisaron registros de los pacientes nacidos y/u hospitalizados dentro de sus 28 días de vida entre el 1 de enero de 2008 y el 31 de diciembre de 2018. Para cada paciente se consignó: edad materna, antecedentes familiares de Síndrome de Down, antecedentes pre y perinatales y resultado de estudio genético. Se consignó la edad al ingreso, el motivo principal de ingreso, comorbilidades, días de hospitalización y fallecimiento. Se excluyeron dos pacientes con más del 50% de ficha in completa. Se exploraron asociaciones entre morbilidades, anomalías y fallecimiento. RESULTADOS: 140 de 79.506 (0,2%) recién nacidos vivos fueron diagnosticados con Síndrome de Down en el período neonatal. 24,7% fueron prematuros y 26,4% tuvieron bajo peso para su edad gestacional. Los porcentajes de morbilidad y hospitalización fueron 83,6% y 90%. La principal causa de ingreso fue la poliglobulia, y la más frecuente hiperbilirrubinemia. Fallecieron 4 pacientes (2,9%) y 70,7% presentó alguna una anomalía congénita, principalmente cardíaca. La mediana de edad materna fue de 36 años y 57,1% tenía 35 años o más. CONCLUSIONES: Esta investigación aporta información relevante para optimizar el manejo perinatal y el seguimiento de los pacientes con Síndrome de Down.

INTRODUCTION: In Chile, Down syndrome has a prevalence of 2.5 in 1,000 live births. These patients present more congenital anomalies and comorbidities than the general population, increasing their hospitaliza tion rate. OBJECTIVE: To describe congenital anomalies and comorbidities of neonates with Down syndrome born and/or hospitalized between 2008 and 2018. PATIENTS AND METHOD: We conducted a retrospective review of patient's medical records born and/or hospitalized during their first 28 days of life between January 1st, 2008, and December 31st, 2018. For each patient, we recorded maternal age, familiar cases of Down Syndrome, pre and perinatal history, genetic study result, as well as age at admission, reason for hospitalization, comorbidities, length of stay, and death. Two patients that had more than 50% of incomplete medical records were excluded. We studied the associations between comorbidities, congenital anomalies, and death. RESULTS: 140 in 79,506 newborns (0.2%) were diagnosed at our center with Down Syndrome in their neonatal period. 24.7% were born preterm and 26.4% had low birth weight for gestational age. Morbidities and hospitalizations were present in 83.6% and 90%, of the study population, respectively. The main reason for hospitalization was polycythemia and the most frequent was hyperbilirubinemia. Four patients died (2.9%) and 70.7% presented at least one congenital anomaly, mainly heart disease. Median maternal age was 36 years and 57.1% of mothers were aged 35 or older. CONCLUSIONS: This cohort of patients with Down Syndrome provides important information for the optimization of their perinatal management and follow-up.

Anomalías dentales en personas con discapacidad / Dental Anomalies in People with Disabilities

RESUMEN Introducción: Durante la odontogénesis se pueden producir malformaciones congénitas que afectan la forma, el número, el tamaño, la estructura, la posición, el color y la erupción de los dientes. En las personas con discapacidades como parálisis cerebral, trastorno del desarrollo intelectual, síndrome de Down y trastorno del espectro autista, pueden presentarse variedad de anomalías dentales. Objetivo: Describir las anomalías dentales en las condiciones de discapacidad de parálisis cerebral, trastorno del desarrollo intelectual, síndrome de Down y trastorno del espectro autista. Métodos: Se realizó una búsqueda bibliográfica en las bases de datos Clinical Key, Medline, Dialnet y SciELO. Se aplicó la lista de comprobación PRISMA. Análisis e integración de la información: Posterior al proceso de lectura y análisis de la información, se recuperaron 800 artículos de las bases de datos, se eliminaron 590 por encontrarse repetidos. Luego de la discriminación, quedaron para revisar 210, a estos restantes se hizo la revisión de texto completo. Se eliminaron 193 no hacían referencia a anomalías dentales y/o a los trastornos o síndromes. De los 17 restantes, solo 15 cumplieron con los criterios de inclusión. Conclusiones: No se encontraron diferencias para afirmar que algunas de las anomalías y alteraciones presentadas correspondan de manera individual a cada tipo de discapacidad. Sin embargo, el síndrome de Down presenta anomalías dentales relacionadas al estado del paciente. La parálisis cerebral reporta otros hallazgos como bruxismo, debido al deficiente desarrollo muscular, lo que afecta la cavidad bucal y sus estructuras(AU)

ABSTRACT Introduction: During odontogenesis, congenital malformations can occur that affect teeth shape, number, size, structure, position, color and eruption. In people with disabilities such as cerebral palsy, intellectual development disorder, Down syndrome, and autism spectrum disorder, a variety of dental abnormalities can occur. Objective: To describe dental anomalies in such disability conditions as cerebral palsy, intellectual development disorder, Down syndrome and autism spectrum disorder. Methods: A bibliographic search was performed in the databases Clinical Key, Medline, Dialnet and SciELO. The PRISMA checklist was applied. Information analysis and integration: After reading and analyzing the information, 800 articles were retrieved from the databases, of which 590 were deleted because they were repeated. After the discrimination, 210 were pending to review; the remaining ones were reviewed full-text. 193 were deleted because they did not do any reference to dental anomalies and/or disorders or syndromes. Of the remaining 17, only 15 met the inclusion criteria. Conclusions: No differences were found to affirm that some of the anomalies and alterations presented correspond individually to each type of disability. However, Down syndrome has dental abnormalities related to patient condition. Cerebral palsy coincides with other findings such as bruxism, due to poor muscle development, which affects the oral cavity and its structures(AU)

Síndrome de Down y su pesquisa durante el primer trimestre de la gestación / Down Syndrome and Screening During Pregnancy First Trimester

RESUMEN Introducción: La pesquisa prenatal de anomalías cromosómicas, mediante el uso de marcadores epidemiológicos y ecográficos del primer trimestre permite identificar gestantes con riesgo incrementado de síndrome de Down. Objetivos: Analizar la edad materna, la translucencia nucal, el ductus venoso y el hueso nasal, durante el cribaje del primer trimestre, en las gestantes que se realizaron diagnóstico prenatal citogenético, con el fin de evaluar la efectividad del mismo en la detección temprana del síndrome Down y su utilidad para la reducción del número de pruebas invasivas. Métodos: Se realizó un estudio descriptivo retrospectivo de corte transversal y se analiza una muestra de 3439 gestantes a las que se realizó el estudio citogenético indicado en el Centro Provincial de Genética Médica de La Habana, en el período comprendido entre el 3 de enero de 2006 y el 30 de diciembre de 2008. Resultados: La edad materna avanzada mostró una sensibilidad de un 87 por ciento del test y una tasa de falsos positivos de 99 por ciento. La translucencia nucal se comportó con una sensibilidad de 10 por ciento. El hueso nasal no mostró asociación con los cariotipos positivos para síndrome de Down. Al no realizarse sistemáticamente la presencia del ductus venoso, no se pudo establecer una asociación estadística. La estimación de riesgo de síndrome de Down basada únicamente en la edad materna avanzada determina una alta tasa de falsos positivos. Por lo que este marcador, unido a la evaluación de los marcadores ecográficos del primer trimestre para recalcular el riesgo individual, puede aumentar la efectividad en el diagnóstico y disminuir el número de pruebas invasivas. Conclusiones: La estimación de riesgo de síndrome de Down basada únicamente en la edad materna avanzada determina una alta tasa de falsos positivos. Por lo que este marcador, unido a la evaluación de los marcadores ecográficos del primer trimestre para recalcular el riesgo individual, puede aumentar la efectividad en el diagnóstico y disminuir el número de pruebas invasivas(AU)

ABSTRACT Introduction: The prenatal investigation of chromosomal abnormalities through the use of epidemiological and echographic markers on the first trimester, allows to identify pregnant women with an increased risk of Down syndrome. Objectives: To analyze maternal age, nuchal translucency, venous ductus and nasal bone, during the first trimester screening, in pregnant women who underwent prenatal cytogenetic diagnosis, in order to evaluate effectiveness in early detection of Down syndrome and the value for reducing the number of invasive tests. Methods: A descriptive retrospective cross-sectional study was carried out and a sample of 3439 pregnant women was studied. The cytogenetic study ordered at Havana Provincial Center for Medical Genetics was carried out from January 3, 2006 to December 30, 2008. Results: Advanced maternal age showed 87 percent sensitivity and 99 percent of false positive rate. Nuchal translucency accounted 10 percent of sensitivity. The nasal bone showed no association with positive karyotypes for Down syndrome. A statistical association of the venous ductus presence could not be established since the search was not systematically. Conclusions: The estimation of Down syndrome risk based solely on advanced maternal age determines high false positive rate. Therefore, this marker, together with the evaluation of the first trimester ultrasound markers for recalculating the individual risk, can increase the diagnostic effectiveness and decrease the number of invasive tests(AU)

The validity and reliability of the CAMDEX-DS for assessing dementia in adults with Down syndrome in Brazil

Objective: Alzheimer's disease occurs at a higher prevalence and an earlier age in individuals with Down syndrome (DS) than typically developing individuals. However, diagnosing dementia in individuals with intellectual disability remains a challenge due to pre-existing cognitive deficits. The aim of this study was to investigate the validity and reliability of the Brazilian version of the Cambridge Examination for Mental Disorders of Older People with Down's syndrome and Others with Intellectual Disabilities (CAMDEX-DS) for individuals with DS. Methods: Two psychiatrists, working independently, evaluated 92 adults with DS ≥ 30 years of age. The concurrent validity of the CAMDEX-DS was analyzed in relation to the gold standard of established international criteria. In a subgroup of 20 subjects, the concurrent validity of the CAMDEX-DS was analyzed in relation to an independent objective assessment of cognitive decline over three years. We analyzed the inter-rater reliability of cognitive assessment. Results: The diagnostic accuracy of the CAMDEX-DS compared to the gold standard was 96.7%. CAMDEX-DS-based diagnosis was considered consistent with cognitive decline. The probability of a participant with dementia having cognitive decline was 83%. Inter-rater reliability for the participant assessment was good, with a kappa of > 0.8 for 93% of the CAMDEX-DS items. Conclusion: The CAMDEX-DS can be considered the first valid and reliable instrument for evaluating dementia in adults with DS in Brazil. Its use in such individuals could improve clinical practice and research.

Síndrome de down: irmãos fazem diferença na qualidade de vida dos pais? / Síndrome de down: ¿hermanos hacen diferencia en la calidad de vida de los padres? / Down syndrome: siblings make difference in the quality of life of their parents?

RESUMO O objetivo deste estudo foi avaliar e discutir a influência da presença de irmãos com desenvolvimento típico na qualidade de vida (QV) de pais de adolescentes com síndrome de Down (SD). Tratou-se de um estudo qualitativo, transversal, descritivo e exploratório. A amostra foi formada por 25 famílias representadas por um cuidador, com filhos em idade entre dez e 19 anos. Essas famílias foram divididas em dois grupos: a) grupo de pais com filhos únicos com SD (GSDU) e b) grupo de pais com filhos com SD e outro (os) filho (os) com desenvolvimento típico (GSDI). Os participantes responderam à entrevista semiestruturada, cujo roteiro focalizava temas como o planejamento familiar, presença do irmão na família, relações entre os irmãos (para GSDI), o futuro do filho com SD e aspectos referentes aos sentimentos dos pais diante do nascimento do filho e da notícia. Os dados foram coletados em um único encontro, individualmente, com duração aproximada de 30 minutos. Os resultados evidenciam que a presença de irmãos com desenvolvimento típico pode mudar a estrutura e a dinâmica familiar, porém, não de forma a influenciar a melhor QV, já que os relatos de ambos os grupos foram muito parecidos.

RESUMEN El objetivo de este estudio fue evaluar y discutir la influencia de la presencia de hermanos con desarrollo típico en la calidad de vida (CV) de padres de adolescentes con síndrome de Down (SD). Se trata de un estudio cualitativo, transversal, descriptivo y exploratorio. La muestra fue formada por 25 familias representadas por un cuidador, con hijos en edad entre 10 y 19 años. Estas familias fueron divididas en dos grupos: a) grupo de padres con hijos únicos con SD (GSDU) y b) grupo de padres con hijos con SD y otro (s) hijo (s) con desarrollo típico (GSDI). Los participantes respondieron a la entrevista semiestructurada, cuyo itinerario enfocaba temas como la planificación familiar, presencia del hermano en la familia, relaciones entre los hermanos (para GSDI), el futuro del hijo con SD y aspectos referentes a los sentimientos de los padres ante el nacimiento del hijo y de las noticias. Los datos fueron recolectados en un solo encuentro, individualmente, con una duración de cerca de 30 minutos. Los resultados evidencian que la presencia de hermanos con desarrollo típico puede cambiar la estructura y la dinámica familiar, pero no para influir en una mejor CV, ya que los relatos de ambos grupos fueron muy parecidos.

ABSTRACT The objective of this study was to evaluate and to discuss the influence of the presence of siblings with typical development on the quality of life (QoL) of parents of adolescents with Down Syndrome (DS). It was a qualitative, cross-sectional, descriptive and exploratory study. The sample consisted of 25 families represented by the caregiver with children aged from 10 to 19 years old. These families were divided in two groups: a) a group of parents with single child with DS (GDSU) and b) group of parents with children with DS and other(s) with typical development (GDSI). Participants answered the semi structured interview whose script focused on topics such as family planning, the presence of the sibling in the family, relationships among the siblings (for GDSI), the future of the child with DS, and aspects related to the parents' feelings about the birth of the child and of the news on his coming to their family. Data were collected, individually, in a single meeting with approximately 30 minutes of duration. The results indicate that the presence of siblings with typical development can change the family structure and dynamics, but not in order to influence a better QoL, since the reports of both groups were very similar.

Experiencias en madres con hijos con síndrome de Down en torno a la recepción del diagnóstico / Experiences of mothers of children with Down syndrome with respect to the notification of diagnosis

En Chile la tasa de Síndrome de Down es de 2,47 por cada mil nacimientos, con tendencia al aumento. El momento del diagnóstico se constituye como un proceso esencial en la asimilación del mismo por parte de las madres. El objetivo del presente es describir las experiencias de madres con niños con Síndrome de Down, al momento de conocer el diagnóstico. METODOLOGÍA: Estudio cualitativo de tipo descriptivo. La muestra se compuso por madres pertenecientes a la corporación "EduDown Providencia". Se realizaron 10 entrevistas semiestructuradas individuales y dos grupos focales, previo consentimiento informado, las entrevistas fueron audiograbadas con transcripciones textuales y luego analizadas. RESULTADOS: Se obtuvieron tres grandes categorías relacionadas con los objetivos del estudio: Factores que influyen en la recepción del diagnóstico, el rol del profesional y redes de apoyo, y dos categorías emergentes. DISCUSIÓN: En el diagnóstico prenatal es relevante preparar a las madres con el fin de orientar y acompañar el proceso desde la noticia y con posterioridad al nacimiento, hecho no manifestado en este estudio. La recomendación al entregar el diagnóstico, principalmente posnatal es: favorecer la privacidad, un ambiente tranquilo, informar a ambos padres acompañados del recién nacido. Las madres de este estudio no presentan sentimientos de culpa, rechazo y negación hacia el hijo, aspectos que aparecen como relevantes en otros estudios. Las madres manifiestan la falta de habilidades que tienen los profesionales para comunicar la noticia y las dificultades económicas que implica tener un hijo con esta condición.

In Chile, the incidence of Down syndrome is 2.47 per one thousand births, a rate which is gradually increasing. The moment of diagnosis is considered to be a crucial moment in the mother's process of assimilation. The objective of the present study is to describe the experiences of mothers of children with Down Syndrome at the time of diagnosis. METHODOLOGY: A descriptive qualitative study. The sample was composed of mothers belonging to the corporation "EduDown Providencia". Ten individual semi-structured interviews and two focus groups were conducted, with prior informed consent. Interviews were recorded, textually transcribed, and analyzed. RESULTS: There were three major categories related to the study objectives ­ factors influencing the reception of the diagnosis, the role of the health professionals, and support networks ­ and two emerging categories. DISCUSSION: In the prenatal diagnosis, it is important to prepare the mothers in order to guide and accompany the process, from the notification until after the birth, a fact which was not manifested in this study. Recommendations regarding the notification of the diagnosis, especially if it is postnatal, include protecting privacy and facilitating a quiet environment, to inform both parents accompanied by the newborn. The mothers of this study did not present feelings of guilt, rejection and denial towards their children, in contrast to the findings of other studies. Mothers discussed the lack of skill that professionals had in communicating the news and the economic difficulties associated with having a child with this condition.

Rol de los marcadores ecográficos secundarios de primer trimestre para la detección de trisomía 21 / Role of first trimester secondary ultrasound markers for trisomy 21 detection

OBJETIVO: Analizar los resultados de los marcadores ecográficos secundarios (hueso nasal, onda a del ductus venoso y regurgitación tricuspídea) y valorar su efectividad para la detección de trisomía 21 y su utilidad para la reducción del número de pruebas invasivas. MÉTODOS: Tras la realización del test combinado de primer trimestre a toda paciente con un riesgo entre 1/101-1/1000 se realizó la valoración de los marcadores secundarios. RESULTADOS: Desde Enero de 2014 a Mayo de 2015 se realizaron 2.660 test combinados del primer trimestre valorándose la edad materna, la traslucencia nucal y la PAPP-A y ßhCG, teniendo una sensibilidad del 90% y una tasa de falsos positivos del 3,2%. Hubo 10 fetos con trisomía 21. La sensibilidad de hueso nasal, ductus venoso y regurgitación tricuspídea fue del 22,2%, 50% y 50% y la especificidad del 99,8%, 96,9% y 98,8% respectivamente. La sensibilidad global del test contingente fue del 90%, con una reducción de la tasa de falsos positivos al 1,6%, lo que se reduciría de 171 a 148 el número de amniocentesis. CONCLUSIÓN: El test contingente es una buena herramienta para reducir la tasa de falsos positivos respecto al test combinado sin disminuir la tasa de detección y con ello reducir la tasa de pruebas invasivas.

AIMS: To analyze the results of the secondary sonographic markers (nasal bone, wave ductus venosus and tricuspid regurgitation) and evaluate its effectiveness for the detection of trisomy 21 and thus reduce the number of invasive tests. METHODS: After completing the first trimester combined test, all patients with a risk between 1/101-1/1000 were evaluated the secondary sonographic markers. RESULTS: From January 2014 to May 2015 2660 combined test being assessed maternal age, nuchal translucency and PAPP-A and ßhCG were performed, with a sensitivity of 90% and a false positive rate of 3.2%. 10 fetuses with trisomy 21 were observed. The sensitivity of nasal bone, ductus venosus and tricuspid regurgitation was 22.2%, 50% and 50% and specificity was 99.8%, 96.9% and 98.8% respectively. The overall sensitivity of contingent test was 90%, with a reduction in false positive rate to 1.6%, which would decrease the number of amniocentesis from 171 to 148. CONCLUSION: The contingent test is a good tool to reduce the rate of false positives with respect to the combined test without decreasing the detection rate and thereby reduce the rate of invasive testing.

Delay and Poor Diagnosis of Down Syndrome in KwaZulu-Natal; South Africa: A Retrospective Review of Postnatal Cytogenetic Testing

BACKGROUND:Down syndrome (DS) is the most common chromosomal disorder in newborns. Until 20 years ago DS was considered rare in black African children in South Africa (SA). Lack of awareness of DS on the part of medical staff in SA; and difficulty in diagnosing it; appear to persist. OBJECTIVES:To establish an epidemiological profile of DS and investigate the ability of clinicians in KwaZulu-Natal Province (KZN); SA; to make accurate clinical diagnoses of DS.METHODS:Records at the South African National Blood Service cytogenetic laboratory in Pinetown; KZN; were examined for all tests for clinically suspected DS undertaken during January 2009 - December 2013 and all cytogenetically proven DS test results. Age at diagnosis; the hospital from where the test was sent and type of chromosomal pattern for each confirmed DS test result were recorded. RESULTS:Of a total of 1 578 tests requested; 875 confirmed DS; indicating that clinicians correctly clinically diagnosed DS 55.4% of the time. The average age of cytogenetic diagnosis of DS was 1 year and 20 days. The minimum population prevalence of DS was 0.8/1 000.CONCLUSIONS: The diagnosis of DS is a challenge in KZN; potentiating missed opportunities for early intervention. The relatively low population prevalence of DS may be attributable to a lack of confirmatory cytogenetic tests or missed clinical diagnoses. It may also be attributable to a high mortality rate for children with DS in the province

Dentists' actions about oral health of individuals with Down Syndrome

To investigate the knowledge and actions of dentists for treatment of individuals with Down syndrome. Methods: A questionnaire was applied to all the dentists (n=90) working at the FHS (Family Health Strategy) modules in the urban limits of Parnaíba, PI, Brazil. Four of the questions in the questionnaire were written according to the Theory of Planned Behavior Table and Likert scale (questions 6,7,9 and 15), in order to analyze the professionals' intentions. Sixteen objective questions were elaborated with the purpose of collecting information about the degree of the dentists' knowledge as regards the intention of attending courses in the patients with special needs area including DS, and interaction with other professionals and families. The option was to use a questionnaire applied to the dentists of the region, from August to November 2014. Results: It was found that most professionals were women and they considered themselves able to identify these patients. Among the professionals, 70% showed they had no difficulty in identifying the patient with DS, and 5.2% had no opinion about the subject. Only 6.6% of the professionals showed to be certain about their aptitude to attend to these patients; 70% were partially apt, that is, they were not absolutely sure about their aptness. There was a statistical relationship between the variables understanding and difficulty in the treatment. There was no statistical relationship between the variable capacity to identify, understanding of the needs and fitness variable in attendance. Conclusions: Patients with Down syndrome need more attention and care of dentists, they must also be involved in a multidisciplinary approach. Most of the professionals do not follow the procedures laid down by the Ministry of Health, but showed interest in attending a course in this area and there is a low number of SD patients being cared in Parnaíba, PI...

Prevalência das malformações congênitas identificadas em fetos com trissomia dos cromossomos 13, 18 e 21 / Prevalence of congenital abnormalities identified in fetuses with 13, 18 and 21 chromosomal trisomy

OBJETIVO: Descrever a prevalência das malformações encontradas nos fetos com trissomia dos cromossomos 13, 18 e 21, identificando as mais frequentes em cada condição. MÉTODOS: Estudo transversal retrospectivo, com análise dos casos de trissomias dos cromossomos 13, 18 e 21 que foram diagnosticados pelo cariótipo fetal obtido por amniocentese/cordocentese, entre outubro de 1994 e maio de 2014, em um Hospital de Ensino da região Sul do Brasil. Foram descritas as malformações identificadas no exame ultrassonográfico morfológico e, posteriormente, confirmadas em exames do recém-nascido e/ou por necropsia fetal. Os resultados foram analisados por meio do teste de Fisher e da análise de variância (ANOVA). O nível de significância empregado foi 5% (p=0,05). RESULTADOS: Em 840 exames realizados, foram diagnosticados 69 casos de trissomias; nove deles foram excluídos por desfecho ocorrido fora do Hospital de Clínicas de Porto Alegre ou prontuário incompleto, restando 60 casos (nove de trissomia do cromossomo 13, 26 do cromossomo 18 e 25 do cromossomo 21). As cardiopatias ocorreram, na maioria dos casos, nos três grupos; a comunicação interventricular foi mais prevalente, em 66,7% do grupo da trissomia 13. As anomalias gastrintestinais aconteceram mais no grupo da trissomia 18, principalmente a onfalocele (38,5%; p<0,01). As anomalias geniturinárias foram significativamente mais frequentes no grupo da trissomia 13 (pielectasia com 55,6% - p<0,01; genitália ambígua com 33,3% - p=0,01). Defeitos do sistema nervoso central foram identificados em todos os casos de trissomia 13. Fendas faciais foram mais prevalentes dentre os fetos com trissomia 13 (66,7%; p<0,01). Malformações nas mãos e nos pés tiveram diferenças estatísticas entre os grupos de trissomia. Os defeitos nas mãos ocorreram em 50% dos casos de trissomia 18 e em 44,4% dos casos de 13 (p<0,01); pé torto congênito foi mais comum no grupo da trissomia 18, descrito em 46,2% dos ...

PURPOSE: To describe the prevalence of malformations found in fetuses with trisomy of chromosomes 13, 18 and 21 by identifying the most frequent within each condition. METHODS: A retrospective cross-sectional study with the analysis of trisomy cases of chromosomes 13, 18 and 21 diagnosed through fetal karyotype obtained by amniocentesis/cordocentesis, between October 1994 and May 2014, at a Teaching Hospital in Brazil Southern Region. Malformations identified through morphological ultrasonography were described and, subsequently, confirmed in newborn examinations and/or fetal autopsy. The results were analyzed using Fisher's test and analysis of variance (ANOVA), with a 5% level of significance (p=0.05). RESULTS: Sixty-nine cases of trisomy were diagnosed among 840 exams; nine were excluded due to outcome outside Hospital de Clínicas de Porto Alegre or incomplete records, remaining 60 cases (nine cases of chromosome 13 trisomy, 26 of chromosome 18, and 25 of chromosome 21). In all three groups, heart disease occurred in most cases; the ventricular septal defect was more prevalent and occurred in 66.7% of the trisomy 13 group. Gastrointestinal abnormalities were more prevalent in the trisomy 18 group, especially omphalocele (38.5%; p<0.01). Genitourinary anomalies were more significantly frequent in the trisomy 13 group (pyelectasis, 55.6% - p<0.01; ambiguous genitalia, 33.3% - p=0.01). Central nervous system defects were identified in all cases of trisomy 13. Facial cracks were significantly more prevalent among fetuses with trisomy 13 (66.7%; p<0.01). Hand and feet malformations significantly differed among the trisomy groups. Hand defects occurred in 50% of trisomy 18 cases, and in 44.4% of all trisomy 13 cases (p<0.01); congenital clubfoot was more common in the trisomy 18 group, being detected in 46.2% of fetuses (p<0.01). The abnormalities were found in 50.9, 27.3 and 21.7% of trisomy 18, 13 and 21 cases respectively. ...

Post-treatment neutrophil-lymphocyte ratio independently predicts amputation in critical limb ischemia without operation

OBJECTIVES: Limited information is available concerning the post-treatment neutrophil-lymphocyte ratio in critical limb ischemia patients who receive conservative therapy. Accordingly, this study was designed to evaluate the predictive value of the post-treatment neutrophil-lymphocyte ratio in critical limb ischemia patients without surgery. METHOD: From January 2009 to January 2011, critical limb ischemia patients were admitted to a vascular center. The demographic data, patient histories, comorbidities and risk factors were documented, and the differential cell count was determined at admission and seven days later after conservative therapy. The cutoff value of the post-treatment neutrophil-lymphocyte ratio was determined by an ROC curve. Patients were divided into groups A and B according to the cutoff value. Amputation-free survival was compared between groups. Univariate and multivariate analyses were used to identify independent risk factors. RESULT: A total of 172 patients were identified with a mean age 71.98±10.09 years; among them, 122 were male. A value of 3.8 was identified as the cutoff value of the post-treatment neutrophil-lymphocyte ratio. Groups A (post-treatment neutrophil-lymphocyte ratio ≥3.8) and B (post-treatment neutrophil-lymphocyte ratio <3.8) showed a significant difference in amputation-free survival (P<0.001). The 1-year, 2-year and 3-year amputation-free survival rates were 79.6%, 55.6% and 46.3%, respectively, in group A; however, in group B, these values were 89.7%, 79.3% and 75.9%, respectively. The post-treatment neutrophil-lymphocyte ratio was identified as an independent predictive factor for amputation in critical limb ischemia patients (P<0.001). CONCLUSION: The post-treatment neutrophil-lymphocyte ratio is an independent predictive factor for amputation in critical limb ischemia patients. Patients with a post-treatment neutrophil-lymphocyte ratio ≥3.8 are likely to suffer from ...

Adaptation in Families of Children with Down Syndrome: A Mixed-methods Design

PURPOSE: The purpose of this study, which was guided by the Resiliency Model of Family Stress, Adjustment, and Adaptation, was twofold: (a) to explore family and parental adaptation and factors influencing family adaptation in Korean families of children with Down syndrome (DS) through a quantitative methodology and (b) to understand the life with a Korean child with DS through a qualitative method. METHODS: A mixed-methods design was adopted. A total of 147 parents of children with DS completed a package of questionnaires, and 19 parents participated in the in-depth interviews. Quantitative and qualitative data were analyzed using stepwise multiple regression and content analysis respectively. RESULTS: According to the quantitative data, the overall family adaptation scores indicated average family functioning. Financial status was an important variable in understanding both family and parental adaptation. Family adaptation was best explained by family problem solving and coping communication, condition management ability, and family hardiness. Family strains and family hardiness were the family factors with the most influence on parental adaption. Qualitative data analysis showed that family life with a child with DS encompassed both positive and negative aspects and was expressed with 5 themes, 10 categories, and 16 sub-categories. CONCLUSION: Results of this study expand our limited knowledge and understanding concerning families of children with DS in Korea and can be used to develop effective interventions to improve the adaptation of family as a unit as well as parental adaptation.

Cost-effectiveness analysis for triple markers serum screening for Down's syndrome in Thai setting.

BACKGROUND: Down’s syndrome is an important congenital chromosomal disorder that can be seen around the world. The antenatal screening for this disorder is an important processing in present obstetrics. OBJECTIVE: Due to the concept of first do no harm, the use of noninvasive test is recommended. The triple marker screening test has been introduced for a few years and acceptable for its effi cacy. RESULT: However, an important concern is on its costeffectiveness. Here, the author analyze and present the cost-effectiveness of the triple markers serum screening for Down’s syndrome in Thai setting. CONCLUSION: According to this work, the cost per effectiveness of triple markers serum screening is slightly lower than standard amniocentesis test.
