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.

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.

Caries in Portuguese children with Down syndrome

OBJECTIVES: Oral health in Down syndrome children has some peculiar aspects that must be considered in the follow-up of these patients. This study focuses on characterizing the environmental and host factors associated with dental caries in Portuguese children with and without Down syndrome. METHODS: A sibling-matched, population-based, cross-sectional survey was performed. RESULTS: Down syndrome children presented a significantly greater percentage of children without caries, 78 percent vs. 58 percent of non-Down syndrome siblings. This difference in the DMFT index (number of decayed, missing and filled teeth) essentially reflects data obtained from treated teeth, for which 91 percent of children with Down syndrome had never had a tooth treated vs. 67 percent of siblings. This result was statistically significant, whereas results for decayed and lost teeth did not differ between Down syndrome children and their unaffected siblings. Additionally, in Down syndrome children, a delayed eruption of the second molar occurs. Down syndrome children and their siblings have similar oral hygiene habits, but a higher percentage of Down syndrome children visit a dentist before the age of three years, in comparison to their siblings. Bruxism was also more common in Down syndrome children compared to their siblings. CONCLUSIONS: Our results show that Portuguese children with Down syndrome have lower caries rates than children without Down syndrome. This reduced prevalence may be associated with the parents' greater concern about oral health care in Down syndrome children, resulting in their taking them sooner to visit a dentist, as well as to a higher bruxism prevalence and delayed tooth eruption.

Prevalência de cardiopatias congênitas em portadores da síndrome de Down na cidade de Pelotas (RS) / Prevalence of congenital heart defects in patients with Down syndrome in the municipality of Pelotas, Brazil

OBJETIVO: Determinar a prevalência de cardiopatias congênitas em portadores da síndrome de Down na cidade de Pelotas (RS), descrevendo os tipos mais frequentes e avaliando os fatores associados. MÉTODOS: Estudo transversal que incluiu crianças portadoras de síndrome de Down nascidas e residentes em Pelotas no período de janeiro de 2000 a dezembro de 2005. Os dados foram obtidos através de entrevistas realizadas nos domicílios dos pacientes, com as mães ou seus familiares legais. Para o estudo dos fatores relacionados à presença de cardiopatia congênita, foram realizadas análises univariada e bivariada. RESULTADOS: Foram entrevistadas 47 mães de pacientes com síndrome de Down, sendo que 22 (46,8 por cento) pacientes apresentavam diagnóstico de cardiopatia congênita. Destes, 28 por cento receberam avaliação cardiológica precoce, antes dos 3 meses de vida. A cardiopatia mais frequente foi a comunicação interatrial (17 por cento); o defeito do septo atrioventricular ocorreu em cinco pacientes. A análise bivariada entre o desfecho presença de cardiopatia congênita e os fatores preditores idade materna, idade paterna, cor dos pais e da criança, presença de outras malformações e sexo da criança mostraram que as associações não foram estatisticamente significativas. CONCLUSÕES: As prevalências de síndrome de Down e de cardiopatia congênita em nossa região apresentam-se semelhantes às encontradas por outros autores, ressaltando-se a importância da suspeita diagnóstica e do encaminhamento precoce por parte dos pediatras para avaliação cardiológica. Destaca-se também o baixo número de pacientes que realizaram cariótipo. Além disso, o número de malformações associadas foi inferior ao encontrado por outros autores.

OBJECTIVE: To determine the prevalence of congenital heart defects in patients with Down syndrome in the municipality of Pelotas, Brazil, describing the most frequent types and assessing the associated factors. METHODS: Cross-sectional study including children with Down syndrome who were born and lived in Pelotas from January 2000 to December 2005. Data were collected by means of home interviews with mothers or guardians. Univariate and bivariate analyses were carried out to analyze the factors related to congenital heart defect. RESULTS: Forty-seven mothers of patients with Down syndrome were interviewed. Twenty-two (46.8 percent) of the patients had a diagnosis of congenital heart defect. Of them, 28 percent had early cardiac evaluation before 3 months of life. The most frequent heart defect was interatrial communication (17 percent); atrioventricular septal defect affected five patients. Bivariate analysis between the outcome congenital heart defect and the predicting factors maternal age, paternal age, parents' and child's skin color, presence of other malformations and child's sex showed that the associations were not statistically significant. CONCLUSIONS: The prevalence of Down syndrome and congenital heart defects in our region is similar to the rates found by other authors; therefore, we highlight the importance of diagnostic suspicion and early referral by pediatricians to cardiac evaluation. Another relevant aspect is the small number of patients who underwent karyotype testing. In addition, the number of associated malformations was lower than that found by other authors.
