Anafilaxia associada à vacina contra sarampo, caxumba e rubéola

A case-control study was carried out aiming to describe the cases and causes of anaphylaxis associated with the vaccine against measles, mumps and rubella. A total of 22 reported cases in children who showed mucocutaneous manifestations, during the Campanha Nacional de Vacinação (Brazilian Vaccination Campaign), conducted in the city of Curitiba, Southern Brazil, in 2004, were studied. In addition, 66 children, who were next to these cases and did not show a symptomatology after the vaccine was applied, were selected. Serum measurements of antibodies for vaccine antigens and total IgE, specific IgE antibody measurements for several allergens, and skin tests were performed. Vaccine response was adequate, specific IgE measurement and skin tests showed that potential allergens in vaccines and atopy were not associated with anaphylactic reactions. Skin tests with the vaccine and dextran were positive in the cases exclusively, suggesting sensitization to certain residual components of the vaccine and possible cross-reaction with dextran.Estudio del tipo caso-control cuyo objetivo fue describir los casos y las causas de anafilaxia asociada a la vacuna contra sarampión, varicela y rubéola. Fueron estudiados 22 casos notificados en niños de Curitiba, Sureste de Brasil, durante Campaña Nacional de Vacunación de 2004, que presentaron manifestaciones mococutáneas. Para el control, fueron seleccionados 66 niños vecinos de los casos, que no presentaron sintomatología posterior a la aplicación vacunal. Fueron realizadas dosificaciones séricas de anticuerpos para los antígenos vacunales, IgE total y específicas para diversos alérgenos, y pruebas cutáneas. La respuesta vacunal fue adecuada, la dosificación de IgE específica y las pruebas cutáneas mostraron que los alérgenos potenciales constituyentes de la vacuna y la atopia no fueron relacionados a las reacciones anafilácticas. Las pruebas cutáneas con la vacuna y el dextrano fueron positivas solamente en los casos, sugiriendo sensibilización por algún componente residual de la vacuna y posible reacción cruzada con el dextrano.Estudo do tipo caso-controle cujo objetivo foi descrever os casos e as causas de anafilaxia associada à vacina contra sarampo, caxumba e rubéola.

Índice de massa corporal, nutrição e atividade física em crianças e adolescentes com síndrome de Down

Objective: To describe and compare the nutritional habits, physical activity, and body mass index (BMI) of children and adolescents with Down syndrome followed up in the specialized outpatient clinic of a tertiary hospital in southern Brazil. Method: Cross-sectional study conducted from the analysis of medical records of patients with Down syndrome at school age and adolescents followed up at the Complexo Hospital de Clínicas of the Universidade Federal do Paraná. The diet was considered adequate if it consisted of foods from all groups in the three main meals and one or two snacks and water in the intervals. A sedentary lifestyle was defined as physical activity time of fewer than 300 minutes per week. Nutritional status was assessed using BMI curves from the World Health Organization, 2007. Results: The study included 755 patients, of whom 236 (31.3%) were children and 519 (68.7%) were adolescents. Overweight and obesity were observed in 10.7% and 14.8% of the population, respectively, without significant gender differences. Inadequate diet was observed in 34.6% and sedentarism in 23.7% of the patients. High BMI was observed in 20.3% of children and 27.9% of adolescents (p=0.026). Sedentarism was observed in 29.5% of adolescents and 11% of children (p<0.001). Inadequate diet was also more prevalent in adolescents but without statistical difference. Patients with high BMI, compared to eutrophic patients, had a higher prevalence of inadequate diet and sedentarism, with statistical significance. In this subgroup, sedentarism was observed in 25% of children and 57.2% of adolescents (p<0.001). Conclusion: Adolescents with Down syndrome have higher rates of high BMI and sedentarism compared to children. Specific studies in health education for this population are necessary to promote healthy lifestyle habits and effectively prevent obesity.  RESUMO: Objetivo: Descrever e comparar hábito nutricional, prática de atividade física e índice de massa corporal (IMC) de crianças e adolescentes com síndrome de Down acompanhados em ambulatório especializado de um hospital terciário no sul do Brasil.

A alimentação foi considerada adequada se consistisse em alimentos de todos os grupos nas três refeições principais e um ou dois lanches e água nos intervalos. Sedentarismo foi definido como tempo de atividade física inferior a 300 minutos por semana. O estado nutricional foi avaliado usando as curvas de IMC da Organização Mundial da Saúde, 2007. Resultados: O estudo incluiu 755 pacientes, sendo 236 (31,3%) crianças e 519 (68,7%) adolescentes. Sobrepeso e obesidade foram observados em 10,7% e 14,8% da população, respectivamente, sem diferença significativa entre os gêneros. Alimentação inadequada foi observada em 34,6% e sedentarismo em 23,7% dos pacientes. IMC elevado foi observado em 20,3% das crianças e 27,9% dos adolescentes (p=0,026). Observou-se sedentarismo em 29,5% dos adolescentes e 11% das crianças (p<0,001). Alimentação inadequada também foi mais prevalente em adolescentes, porém sem diferença estatística. Pacientes com IMC elevado, em comparação com eutróficos, tiveram maior prevalência de alimentação inadequada e sedentarismo, com significância estatística. Nesse subgrupo, o sedentarismo foi observado em 25% das crianças e 57,2% dos adolescentes (p<0,001). Conclusão: Adolescentes com síndrome de Down apresentam maiores taxas de IMC elevado e sedentarismo comparados com crianças. Estudos específicos em educação em saúde para essa população são necessários com o objetivo de promover hábitos de vida saudáveis e prevenir a obesidade com efetividade

Telemedicina em um Ambulatório de Síndrome de Down no Brasil durante a Pandemia do Covid-19

OBJECTIVE: This study aims to analyze the use of telemedicine during the Covid-19 pandemic (efficiency, effectiveness, positive and negative points as a modality of care) and educational and therapeutic parameters of the patient with Down syndrome during this period. METODOLOGY: Data were collected remotely using an online form created by the authors and answered by patients or their caregivers from the Down Syndrome Outpatient Clinic of a university hospital in the South of Brazil. RESULTS: 65 responses were received, with 44.6% of the participants residing in Curitiba, 32.3% in the metropolitan region, 12.3% in the interior of Paraná and 10.8% in other states. Twenty-eight (43.1%) receive the Continued Benefit of Social Assistance. As for education, 41.5% attended special schools, 26.2% regular education, 10.8% both regular education and special education, and 21.5% do not studied. During the pandemic, 81.3% had remote school activities, and 41.3% did not undergo therapy. Health needs were met with consultation through telemedicine in 96.7%. Strengths: not having to go to the clinic (59.4%), easy access to the consultation (71.9%), feeling comfortable with the telemedicine consultation (46.9%), feeling understood by doctors (42.2%), having their doubts and concerns answered (62.5%), not having to miss work (25%). Weakness: impossibility of carrying out the physical examination (100%), connection problems (18.6%), feeling uncomfortable with the telemedicine consultation (10%). CONCLUSION: Telemedicine was a viable option for patients with Down syndrome during the Covid-19 pandemic with many positive points. During the pandemic, 81.3% had remote school activities, and 41.3% didnt go to therapies

Zika Virus Infection at Different Pregnancy Stages: Anatomopathological Findings, Target Cells and Viral Persistence in Placental Tissues

Zika virus (ZIKV) infection in humans has been associated with congenital malformations and other neurological disorders, such as Guillain-Barré syndrome. The mechanism(s) of ZIKV intrauterine transmission, the cell types involved, the most vulnerable period of pregnancy for severe outcomes from infection and other physiopathological aspects are not completely elucidated. In this study, we analyzed placental samples obtained at the time of delivery from a group of 24 women diagnosed with ZIKV infection during the first, second or third trimesters of pregnancy. Villous immaturity was the main histological finding in the placental tissues, although placentas without alterations were also frequently observed. Significant enhancement of the number of syncytial sprouts was observed in the placentas of women infected during the third trimester, indicating the development of placental abnormalities after ZIKV infection. Hyperplasia of Hofbauer cells (HCs) was also observed in these third-trimester placental tissues, and remarkably, HCs were the only ZIKV-positive fetal cells found in the placentas studied that persisted until birth, as revealed by immunohistochemical (IHC) analysis. Thirty-three percent of women infected during pregnancy delivered infants with congenital abnormalities, although no pattern correlating the gestational stage at infection, the IHC positivity of HCs in placental tissues and the presence of congenital malformations at birth was observed. Placental tissue analysis enabled us to confirm maternal ZIKV infection in cases where serum from the acute infection phase was not available, which reinforces the importance of this technique in identifying possible causal factors of birth defects. The results we observed in the samples from naturally infected pregnant women may contribute to the understanding of some aspects of the pathophysiology of ZIKV

Nutritional status of children and adolescents with Down syndrome

Introduction: Inadequate eating habits and physical inactivity directly contribute to changes in nutritional status. Patients with Down syndrome (DS) are more prone to obesity due to genetic and / or environmental factors, which favors cardiovascular diseases with the possibility of complications and reduced life expectancy. Objective: To describe the nutritional status of patients followed up at an outpatient referral center for Down's syndrome in a Brazilian tertiary hospital. Methodology: Retrospective, cross-sectional and descriptive study with analysis of 1,056 medical records of patients with DS, from 2014 to 2016. Food was considered adequate if it consisted of food from all groups in three main meals and one / two snacks and water in breaks. Sedentary lifestyle was considered if the time of physical activity was less than 300 minutes per week. Nutritional status was assessed using the World Health Organization (WHO) body mass index curves, 2007. The data were analyzed using the Excel program. The Pearson's chi-square test was used to compare data from children and adolescents. The level of significance was set at p <0.05. Approved by the Human Research Ethics Committee of the service referred to under number 04542712.3.0000.0096. Results: 517 children (3 to 9 years, 11 months and 29 days) and 539 adolescents (10 to 20 years of age) were evaluated. Food was adequate for 395 (76.4%) children and 336 (62.3%) adolescents (p <0.001). The nutritional status was adequate in 397 (76.8%) children and 371 (68.8%) adolescents, overweight was seen in 40 (8%) children and 64 (12%) adolescents (p <0.01); obesity in 50 (9.7%) children and 96 (17.8%) adolescents (p <0.001) and thinness in 30 (5.8%) children and 8 (1.5%) adolescents (p <0.001). As for physical activity, 39 (7.5%) children and 168 (31.1%) adolescents (p <0.001) were sedentary. Discussion and Conclusion: There was an association of increased body mass index with inadequate diet and physical inactivity with increasing age of patients. Individuals with DS, children and adults, are 30 to 50% susceptible to becoming obese in childhood. According to the classic literature, the presence of hypothyroidism, food error and physical inactivity are associated with overweight and obesity in this population. The prevalence of overweight and obesity in children with intellectual disabilities is almost twice as high as in peers without disabilities. And it is observed that people with DS are less involved in physical activities compared to their siblings. For adolescents, behavioral problems such as impulsiveness, recommendation behavior and disobedience discourage good lifestyle habits. Food inadequacy and physical inactivity were more prevalent in the adolescent population. The body mass index increases the age, therefore the consolidation according to the good practices of life habits requires continuous education of the family and the individual. Multidisciplinary monitoring is essential for the prevention of overweight and obesity

Down syndrome: Prevalence and distribution of congenital heart disease in Brazil

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
