Analysis for trends in disease burden of congenital birth defects among children under 5 years old in China / 中南大学学报(医学版)

OBJECTIVES@#Congenital birth defects are the main source of disease burden among children under 5 years old in China. This study aims to compare the trends in disease burden of different congenital birth defects among Chinese children under 5 years old from 1990 to 2019, and to provide a scientific basis for strengthening the comprehensive prevention and control of birth defects.@*METHODS@#Based on data from the Global Burden Disease (GBD) in 2019, the incidence mortality rate, and disability-adjusted life years (DALYs) rate of congenital birth defects among Chinese children under 5 years old from 1990 to 2019 were selected as evaluation indicators. The Joinpoint regression model was used to analyze the trends in disease burden of different types with congenital birth defects over three decades. The study also compared the differences in disease burden of congenital birth defects among children under 5 years old by gender.@*RESULTS@#Compared to 1990, the DALYs rates of congenital heart anomalies (1 931.91/100 000), digestive congenital anomalies (364.63/100 000), neural tube defects (277.20/100 000), congenital musculoskeletal and limb anomalies (133.33/100 000), and Down syndrome (128.22/100 000) in children under 5 years old in China in 2019 were decreased 70.78%, 71.61%, 86.21%, 36.84% and 73.65%, respectively. From 1990 to 2019, the mortality rates and DALYs rates of different congenital birth defects showed an overall downward trend, but the incidence of digestive congenital anomalies and Down syndrome showed an upward trend after 2005 and 2001, respectively. Except for congenital musculoskeletal and limb anomalies, incidence of the remaining categories of birth defects were higher in boys than that in girls.@*CONCLUSIONS@#The disease burden of congenital birth defects in children under 5 years old in China is decreased substantially from 1990 to 2019, but the burden of congenital heart anomalies is still serious and the incidence of some birth defect diseases is on the rise, and it is still crucial to strengthen the prevention and treatment for birth defects in children and propose targeted measures according to their gender characteristics.

Resumen El objetivo del presente estudio fue realizar una revisión de la bibliografía, estructurada en torno a la influencia del equilibrio en la calidad de vida de las personas con síndrome de Down en edad escolar y adulta. Para la búsqueda, se introdujo en las bases de datos WOS, Scopus y SPORTDiscus las palabras clave "Down Syndrome", "Balance" y "Quality of life". Para ello, se ha seguido la propuesta de revisión literaria de Gamonales, Muñoz-Jiménez, León & Ibáñez (2018), con cuatro criterios de inclusión: i) Mencionar la influencia del equilibrio en la CDV de las personas con SD (mínimo 20 palabras), ii) Seleccionar exclusivamente artículos científicos, iii) Tener acceso al texto completo o Resumen, y iv) Estar escrito en inglés, portugués o español. Los documentos revisados sobre la influencia del equilibrio en personas con síndrome de Down abordan tópicos de investigación diferentes. De los treinta y siete artículos localizados en la primera búsqueda, siete de ellos cumplen con los criterios de inclusión. Los textos científicos revisados muestran que la práctica de ejercicio físico específico produce mejoras en el equilibrio y en la calidad de vida de las personas con síndrome de Down, lo que permite establecer recomendaciones básicas de actividad física para este colectivo.

Abstract The study aims to conduct a bibliographic and structured review based on the results found around the influence of balance on the quality of life of people with Down Syndrome (DS) in school and adult ages. For references searching, the following keywords were used as descriptors: "Down Syndrome," "Balance," and "Quality of life". The words were always introduced in English and computerized databases; SCOPUS, WOS, and SPORTDiscus were used. Four inclusion criteria were introduced to limit the search: i) mentioning the influence of balance on the QOL of people with DS, ii) taking exclusively into consideration scientific articles, iii) having access to the full text or abstract, and iv) being written in English, Portuguese, or Spanish. In conclusion, the documents about the influence of balance in people with Down Syndrome address different research topics. Of the thirty-four articles located in the first search, seven of them meet the inclusion criteria. The reviewed scientific literature shows that the practice of physical exercise and specific training produce improvements in balance and the quality of life of people with Down syndrome, which allows establishing the recommendation to specifically train balance during physical activity sessions since there is evidence of positive effects for this group.

Introduction: congenital anomalies (CA) are a public health problem with an impact on childhood, infant mortality (IM) and disability. In Uruguay, as well as in other developed countries, CA and prematurity are the main causes of IM. Objectives: analyze the most frequent anomalies in the country in 2011-2014 and evaluate risk factors. Material and methods: the data were obtained from the National Record of Congenital Defects and Rare Diseases and health statistics from the Ministry of Public Health. Results: it was determined that practically half of the cases were: congenital heart disease, Down syndrome and Neural Tube Defects (anencephaly, encephalocele and myelomeningocele), accounting for 0.42% (812/191,820) and 2.85% (38/1334) of live births and stillbirths respectively. The prevalence per 10,000 NV and stillbirths were: 38.52 and 149.93 for Congenital Heart Disease; 3.6 and 7.5 for Down Syndrome; 2.1 and 127.4 for neural tube defects. Advanced maternal age was the main risk factor for Down syndrome. The risk factors observed in the three selected anomalies were: prematurity, neonatal depression and low birth weight. Conclusions: congenital anomalies in general, and those selected in this study in particular, are a relevant cause of morbidity and mortality in newborns and infants, likely to be prevented. Early diagnosis is essential for planning specialized health services. The results presented in the present paper can be used as a baseline to measure the impact of health actions at national level.

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.

Prevalencia al nacimiento de síndrome de Down, según edad materna en Costa Rica, 1996-2016 / Birth prevalence of Down syndrome according maternal age in Costa Rica, 1996-2016

Resumen Justificación: El síndrome de Down es la cromosomopatía más frecuente en Costa Rica y el mundo, así como la principal causa de discapacidad intelectual. La edad materna avanzada es el mayor factor de riesgo conocido para este padecimiento. El objetivo fue conocer la tendencia de síndrome de Down en nacidos vivos, según edad materna en Costa Rica. Métodos: Se realizó un estudio observacional de prevalencias de todos los casos de síndrome de Down nacidos vivos en Costa Rica entre 1996-2016, reportados al Centro Nacional de Registro de Enfermedades Congénitas, programa nacional de vigilancia de los defectos congénitos. Se determinó la tendencia y prevalencia en nacidos vivos según edad materna: < 20, 20-34 y 35 años o más, y según período: 1996-2007 y 2008-2016. Se realizó una regresión de Poisson, tomando como referencias el grupo 20-34 años y 1996-2002, y se compararon estimados mediante chi cuadrado de Wald. Se calculó la razón de prevalencias en madres ≥35 años y la fracción atribuible poblacional para este estrato. Por último, se comparó la tendencia del síndrome de Down con la tendencia de la tasa de fecundidad específica en madres ≥35 años en el país, para el período en estudio. Resultados: Para 1996-2016, la prevalencia de síndrome de Down en nacidos vivos fue de 1,02 x 1000 (IC95 %: 0,97-1,07). Hubo un aumento significativo de 0,91 (1996-2007) a 1,16 x 1000 (2008-2016), a expensas de la prevalencia en madres ≥35 años, la cual aumentó de 4,27 a 5,44 x 1000; mientras que la tasa de fecundidad en estas madres cayó significativamente de 20,15 x 1000 (IC95 %: 20,02-20,28) en 1996-2007, a 15,58 x 1000 (IC95 % 15,46-15,70) para o 2008-2016. La edad materna media en SD fue de 32,2 años, contra 25,5 años para la población general (p≤0,001). La razón de prevalencia ajustada por período, en madres de ≥35 años, contra madres de 20-34 años fue de 8,05 (IC95 % 7,25-8,95) y la fracción atribuible poblacional del 41,22 %. Conclusiones: La prevalencia al nacimiento de síndrome de Down en Costa Rica aumentó a expensas de la prevalencia en madres ≥35 años, pese a que la tasa de fecundidad específica en esas mujeres cayó significativamente. La inclusión del Hospital Nacional de Niños como institución de referencia nacional para este síndrome, dentro de la red de vigilancia de los defectos congénitos, pudo ser un factor determinante en el aumento de la prevalencia.

Abstract Justification: Down syndrome is the most frequent chromosomopathy in Costa Rica and the world, as well as the main cause of intellectual disability. Advanced maternal age is the main known risk factor for this condition. The objective was to know the trend of Down syndrome in live births according to maternal age in Costa Rica. Methods: A prevalence study was made of all Down syndrome cases, born alive in Costa Rica from 1996 to 2016 and reported to the Costa Rican Births Defects Register Center, a national program for the monitoring of congenital defects. The trend and prevalence in live births was determined, according to maternal age: <20, 20-34 and 35 years or more, and according to period: 1996-2007 and 2008-2016. A Poisson regression was carried out, taking as references the group 20-34 years and the period 1996-2002 and the results were compared Wald's chi-square. The prevalence ratio in mothers ≥35 years and the population attributable fraction was calculated for this stratum. Finally, the trend of Down syndrome was compared with the trend of the specific fertility rate in mothers ≥35 years. Results: For 1996-2016 the prevalence of Down syndrome in live births was 1.02 x 1000 (95% CI: 0.97-1.07). There was a significant increase from 0.91 (1996-2007) to 1.16 x 1000 (2008-2016), at the expense of the prevalence in mothers ≥35 years, which increased from 4.27 to 5.44 x 1000; while the fertility rate in these mothers fell significantly from 20.15 x 1000 (95% CI: 20.02-20.28) in 1996-2007, to 15.58 x 1000 (95% CI 15.46-15.70) in 2008-2016. Maternal age mean MS in SD was 32.2 years, versus 25.5 years in the general population (p≤0.001). The prevalence ratio adjusted by period, in mothers of ≥35 years, against mothers of 20-34 years was of 8.05 (95% CI 7.25-8.95) and the population attributable fraction was 41.22%. Conclusions: The livebirth`s prevalence of Down syndrome in Costa Rica increased for the study period, at the expense of prevalence in mothers ≥35 years, although the specific fertility rate in these women fell significantly. The inclusion of the National Children's Hospital - as a national reference institution for this syndrome - within the surveillance network of congenital defects, could be a determining factor in in prevalence rise.

Enfermedad celíaca en niños con síndrome de Down / Celiac disease in children with Down syndrome

INTRODUCCIÓN: La enfermedad celíaca (EC) en niños con síndrome de Down (SD) ha sido publicada por varios paí ses, sin que existan datos para Colombia. OBJETIVO: Determinar la frecuencia y factores relacionados de EC en niños con SD, comparado con un grupo de niños sin SD, analizando las manifestaciones clínicas, inmunológicas y genéticas. PACIENTES Y MÉTODO: Fueron estudiados 209 niños, 1-18 años de edad (8,4 ± 4,1 años; 55,5% sexo femenino): 97 con SD y 112 sin SD usando como marcador serológico los anticuerpos anti-transglutaminasa (tTG2); se estudiaron variables de edad, genero, raza, ori gen, peso, talla y síntomas digestivos. A los niños con tTG2 positivos, se les realizó biopsia duodenal y genotipo. Se estimó la proporción de niños con SD, sin SD y EC y su IC95%; medidas de tendencia central, análisis univariado y bivariado, siendo significativa una p < 0,05. RESULTADOS: Ocho niños con SD (8,2%) y 5 niños sin SD (4,5%) fueron tTG2 positivos (p = 0,200). Ninguno presentó deficiencia de IgA sérica. Un niño con SD presentó EC con Marsh II (1,0%); y 2 niños con SD (2,1%) y 2 sin SD (1,8%), presentaron EC potencial (p = 0,432). Tres niños fueron HLA-DQ2. Hubo mayor opor tunidad de presentar EC en el grupo de pre-escolares (OR = 6,14 IC95% = 0,41-87,35 p = 0,0462). CONCLUSIONES: La frecuencia de EC por biopsia intestinal en estos niños con SD es muy inferior a lo relatado en la literatura, estando asociada al pre-escolar, y siendo su principal alelo el DQ2, hallazgos similares a lo descrito a nivel mundial.

INTRODUCTION: Celiac disease (CD) in children with Down syndrome (DS) has been published by several countries, without available data for Colombia. OBJECTIVE: To determine the frequency and related factors of CD in children with DS, compared with a group of children without DS, analyzing the clinical, im munological, and genetic manifestations. PATIENTS AND METHOD: A total of 209 children between 1-18 years of age (8.4 ± 4.1 years, 55.5% female) were studied, 97 with DS and 112 without DS, using anti-transglutaminase antibodies as serological marker (tTG2). Variables of age, gender, race, ori gin, weight, height, and digestive symptoms were studied. Children with positive tTG2 underwent duodenal biopsy and genotype. The proportion of children with DS, without DS, and CD was esti mated and their 95% CI; measures of central tendency, univariate and bivariate analysis, considering a p < 0.05 significant. RESULTS: Eight children with DS (8.2%) and five children without DS (4.5%) were tTG2 positive (p = 0.200). None presented serum IgA deficiency. One child with DS presented CD with Marsh II (1.0%), and two children with DS (2.1%) and two without DS (1.8%), presen ted potential CD (p = 0.432). Three children were HLA-DQ2. CD was more likely in the preschool group (OR = 6.14 95%CI = 0.41-87.35 p = 0.0462). CONCLUSIONS: The CD frequency due to intestinal biopsy in children with DS is much lower than that reported in the literature, being associated with preschool, and having DQ2 as its main allele. These findings are similar to those described worldwide.

Down syndrome in adults: success and challenge / Síndrome de Down em adultos: sucessos e desafios

The estimated average survival of people with Down syndrome (DS) is currently over 50 years of age. This demographic finding warrants attention of health professionals who will care for an increasing number of adults with DS. Clinical evaluation of adults with DS should correlate characteristics inherent to the age group, especially the peculiarities produced by the syndrome. The present article proposes the development of preventive and vaccination programs ­ according to gender and age ­ and screening of diseases and conditions associated with the syndrome: 1) endocrine diseases; 2) cardiac diseases; 3) mental health; 4) dental care; 5) sensory organs; 6) osteoarticular abnormalities; 7) skin and appendages; 8) gastrointestinal diseases; and 9) cancer. However, there is scant information on the impact of comorbidities on life expectancy and quality of life or on the social and hospital costs of adults with DS.

A estimativa da sobrevida média de indivíduos com síndrome de Down (SD) passa atualmente dos 50 anos de idade. Esse dado demográfico justifica a atenção de profissionais da saúde que prestarão cuidados a um número crescente de adultos com SD. A avaliação clínica desse grupo de pacientes adultos deve correlacionar características inerentes à faixa etária, principalmente as peculiaridades produzidas pela síndrome. O presente artigo propõe o desenvolvimento de programas de prevenção e vacinação ­ conforme gênero e idade ­ e triagem de doenças e quadros associados à síndrome: 1) doenças endócrinas; 2) doenças cardíacas; 3) saúde mental; 4) saúde bucal; 5) órgãos sensoriais; 6) anomalias osteoarticulares; 7) pele e anexos; 8) doenças gastrointestinais; 9) câncer. Entretanto, há poucas informações sobre o impacto das comorbidades na expectativa de vida e na qualidade de vida, além dos custos hospitalares e sociais de adultos com SD.

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.

Prevalencia del síndrome de Down al nacimiento en Argentina / Birth prevalence of Down syndrome in Argentina

RESUMEN El objetivo de este trabajo fue describir la prevalencia al nacimiento del síndrome de Down en Argentina. Se calculó la prevalencia por jurisdicción y edad materna para el período 2009-2015 y se comparó la prevalencia y proporción del diagnóstico prenatal según subsector (público y privado) y nivel de complejidad de las maternidades. Se analizó la asociación con el peso y la edad gestacional al nacer. La fuente de datos fue la Red Nacional de Anomalías Congénitas (RENAC). La prevalencia fue de 17,26 por cada 10.000 nacimientos; por jurisdicciones varió entre 10,99 y 23,71, y por edad materna entre 10,32 en <20 años y 158,06 en ≥45 años. En hospitales del subsector privado hubo una mayor proporción de diagnóstico prenatal y una mayor prevalencia, esta última atribuible a diferencias en la estructura de edad materna. Se observó una correlación negativa entre el peso al nacer y este síndrome ( ß=-294,7; p<0,001). No se evidenció diferencia en la mediana de la edad gestacional al nacer entre recién nacidos con síndrome de Down y neonatos sin anomalías mayores, pero sí en la distribución de la edad gestacional. El conocimiento de ciertas características epidemiológicas podrá contribuir a la implementación de políticas de salud.

ABSTRACT The aim of this study was to describe the prevalence at birth of Down syndrome in Argentina. The prevalence by jurisdiction and maternal age was calculated for the 2009-2015 period and the prevalence and proportion of prenatal diagnosis was compared according to sub-sector (public and private) and complexity level of the maternity wards. The association of Down syndrome with birth weight and gestational age was analyzed. The data source was the National Network of Congenital Anomalies of Argentina [Red Nacional de Anomalías Congénitas] (RENAC). The prevalence was 17.26 per 10,000 births; by jurisdictions it varied between 10.99 and 23.71; and by maternal age, between 10.32 in women <20 years of age and 158.06 in those ≥45 years of age. In hospitals of the private subsector there was a higher prevalence, attributable to differences in the structure of maternal age, and a greater proportion of prenatal diagnosis. There was a negative correlation between birth weight and Down syndrome ( ß=-294.7; p<0.001). No difference in the median gestational age at birth between Down syndrome newborns and newborns without major anomalies was found, but the distribution of gestational age differed. Knowledge of certain epidemiological characteristics of this health issue could contribute to the implementation of health policies.

Frecuencia de niños con síndrome de Down hospitalizados por virus respiratorio sincicial en el Hospital Roberto del Rio en los años 2014-2015 / Frequency of children with Down syndrome hospitalized for respiratory syncytial virus at Roberto del Rio Hospital in the years 2014-2015

Introducción La infección respiratoria aguda en nuestro medio generalmente es de característica viral, siendo el virus respiratorio sincicial (VRS) el principal responsable de hospitalización en niños menores de dos años. Es más susceptible en los prematuros, con cardiopatía asociada y con síndrome de Down. (DS). El objetivo principal de este estudio es dar a conocer la incidencia de infección y hospitalización de niños con síndrome de Down por VRS. Para lo cual se realiza la revisión de la base de datos con el número de niños que se atienden en el Hospital Roberto del Río, durante los años 2014-2015, así como la revisión de sus historias clínicas de SD atendidos en el Hospital Roberto del Rio durante este periodo. Resultados: SE analizan 60 niños con SD atendidos en el hospital Roberto del Río que se hospitalizan con infección respiratoria aguda, en su mayoría son de sexo femenino, con VRS negativo, con un rango de hospitalización mínimo entre 7 a 10 días, y máximo de 20 días, y se asocian con más frecuencia a cardiopatía congénita. Se observó un prematuro SD solamente en el estudio. Conclusiones: El 40% de niños atendidos en el Hospital Roberto del Rio se hospitalizan con infección respiratoria aguda y un 41% de los hospitalizados están asociados al VRS. Los niños con SD y con condiciones clínicas asociadas como cardiopatía congénita tienen una alta incidencia de infección y hospitalización.

Summary Introduction: Acute respiratory infection in our environment is usually viral in nature, with respiratory syncytial virus (RSV) being the main cause of hospitalization in children under two years of age, with preterm infants with associated heart disease and Down syndrome being more susceptible. The main objective of this study is to describe the incidence of infection and hospitalization of children with Down syndrome (DS) due to RSV. Method: For this purpose, the database is revised with the number of children with DS treated at the Roberto del Río Children´s Hospital, during the years 2014-2015, as well as the review of their clinical histories. We analyzed 60 cases of children with DS. Results: Hospitalized SD children with acute respiratory infection, were mostly female, with negative RSV, hospitalization range between 7 to 10 days, and a maximum of 20 days, most associated with congenital heart disease. A premature DS baby was observed only in the study. Conclusions: Forty percent of the DS children treated at the Roberto del Rio Children´s Hospital hospitalized with acute respiratory infection and 41% of hospitalized patients were related to RSV, children with DS and associated clinical conditions such as congenital heart disease have a higher incidence of infection and hospitalization.

Perfil de morbilidad en adolescentes chilenos con síndrome de Down / Morbidity profile among adolescents with Down syndrome

Background: There is a paucity of information about morbidity and mortality of adolescents with Down syndrome (DS). Aim: To describe morbidity and mortality of a cohort of Chilean adolescents with DS. Material and Methods: Review of electronic clinical records of 67 ambulatory patients with DS aged 10 to 20 years (37 women), seen between the years 2007 and 2014 in outpatient clinics of a University hospital. Results: The mean age at the last consultation was 13 ± 3 years. Ninety-eight percent of patients had a chronic condition: 37.1% where overweight or obese, 58.2% had a congenital heart disease, 11.9% where being evaluated or had the diagnosis of autism and 44.8% had hypothyroidism. Pubertal development was consistent with chronologic age in 93.7% of patients. In three patients puberty had been suppressed. In women, average age of menarche was 12.2 ± 1.1 years. There were no deaths reported. Conclusions: There was a high rate of comorbidities in this group of adolescents with DS, most of them with frequencies comparable to those reported in literature.

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...

Down syndrome: Prevalence and distribution of congenital heart disease in Brazil / Síndrome de Down: prevalência e distribuição de cardiopatia congênita no Brasil

ABSTRACT CONTEXT AND OBJECTIVE: Down syndrome is the most common genetic disorder, affecting 1/700 live births. Among the clinical findings, one constant concern is the high prevalence of congenital heart disease. The objective of this study was to determine the prevalence and profile of congenital heart disease among patients attended at a Down syndrome outpatient clinic in southern Brazil between 2005 and 2013. DESIGN AND SETTING : Cross-sectional study conducted in a referral center. METHODS : Data were retrospectively gathered from the medical files of 1,207 patients with Down syndrome, among whom 604 (50.0%) had been diagnosed with congenital heart disease. These data were subjected to descriptive analysis using the Statistica software. RESULTS : Among the 604 patients with congenital heart disease, 338 (55.8%) were male and 269 (44.5%) were female. The most common heart diseases were atrial septal defect in 254 patients (42.1%); total atrioventricular septal defect in 91 (15.1%); atrial septal defect and ventricular septal defect in 88 (14.6%); ventricular septal defect in 77 (12.7%); patent ductus arteriosus in 40 (6.6%); patent foramen ovale in 34 (5.6%) patients; tetralogy of Fallot in 12 (2%); and other diseases in 8 (1.3%). Pulmonary hypertension was present in 57 (9.4%). Out of the total, 150 patients (24.8%) underwent cardiac surgery. CONCLUSION : The high prevalence of congenital heart disease among the patients at the Down syndrome outpatient clinic (50%) was similar to findings from other studies and justifies investigation during the neonatal period, so as to decrease mortality and morbidity.

RESUMO CONTEXTO E OBJETIVO : A síndrome de Down é a anomalia genética mais comum e afeta 1/700 nascidos vivos. Entre os achados clínicos, uma preocupação constante é a alta prevalência de cardiopatia congênita e o objetivo do presente estudo é determinar a prevalência e o perfil de cardiopatia congênita em pacientes atendidos em um ambulatório de síndrome de Down no período de 2005 a 2013 no sul do Brasil. TIPO DE ESTUDO E LOCAL : Estudo transversal conduzido em um centro de referência. MÉTODOS : Foi realizada coleta retrospectiva de dados de 1.207 prontuários de pacientes com síndrome de Down, com 604 (50,0%) diagnosticados com cardiopatia congênita. Os dados foram submetidos a análise descritiva, utilizando-se o programa Statistica. RESULTADOS : Entre os 604 pacientes com cardiopatia congênita, 338 (55,8%) eram do sexo masculino e 269 (44,5%) do feminino. A cardiopatia mais comum foi comunicação interatrial, observada em 254 (42,1%) pacientes, defeito de septo atrioventricular total, em 91 (15,1%), comunicação interatrial em conjunto com comunicação interventricular, em 88 (14,6%), comunicação interventricular, em 77 (12,7%), persistência do canal arterial, em 40 (6,6%), forame oval patente, em 34 (5,6%), tetralogia de Fallot, em 12 (2%) e outras cardiopatias observadas em oito (1,3%) pacientes. Hipertensão pulmonar esteve presente em 57 (9,4%). Do total, 150 (24,8%) pacientes foram submetidos a cirurgia cardíaca. CONCLUSÃO : A elevada prevalência das cardiopatias congênitas nos pacientes do ambulatório da síndrome de Down, de 50%, semelhante à encontrada em outros estudos, justifica a investigação no período neonatal, com diminuição da mortalidade e morbidade.

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. ...

Malnutrición por exceso: alta frecuencia de sobrepeso y obesidad en escolares chilenos con síndrome de Down / High rates of overweight and obesity in Chilean children with Down syndrome

Background: Overweight and obesity in Down syndrome (DS) is a common problem. Chile has a high prevalence of DS. Aim: To determine overweight and obesity rates in students with DS and evaluate the concordance of three different growth charts. Material and Methods: Seventy nine students with DS aged between 6 and 18 years (56% males), from three different schools, were included. Weight and height were measured and their body mass index (BMI) was calculated. The nutritional diagnosis was made according to BMI. Myrelid SDM/2002, National Center for Health Statistics (NCHS)/2000, World Health Organization (WHO)/2007 charts for people with DS were used. Results: Thirty percent of participants had hypothyroidism, 22.8% congenital heart disease and 5% asthma. Overweight and obesity rates according to SDM/2002, NCHS/2000 and WHO/2007 were 43, 57 and 66% respectively. The concordance between WHO/2007 and NCHS/2000 was almost perfect, but not with SDM/2002. Conclusions: A high rate of overweight and obesity was found in this group of children with DS, independent of the charts used or their comorbidities.
