Elimination diet in food allergy: friend or foe?

Abstract Objectives To review and discuss the role of an elimination diet in food-allergic children, emphasizing nutritional aspects for a better practical approach. Sources Non-systematic review of the literature. Findings Under an elimination diet, food-allergic patients may suffer from growth impairment or obesity and compromised quality of life. Disease phenotype, age, type, number of foods excluded, comorbidities, eating difficulties, economic status, and food availability must be considered for an appropriate diet prescription. Diet quality encompasses diversity and degree of food processing, which may alter immune regulation. Conclusions A friendly food elimination diet prescription depends on a multidisciplinary approach beyond macro and micronutrients.

Teaching and mental health in medical students

SUMMARY OBJECTIVE: The objective of this study was to evaluate the relationship between quality of life, perceived stress, anxiety, and depression in medical students and the university teaching method: traditional method versus active methodology. METHODS: Four questionnaires were administered to volunteer students (n=361) enrolled in two institutions that employ active (Universidade Tiradentes) or traditional (Faculdade de Medicina do ABC) teaching methodology: socioeconomic level; brief quality of life (World Health Organization Quality of Life-Bref); perceived stress scale (PSS10); and depression and anxiety scale (hospital anxiety and depression scale). RESULTS: Of the students who responded to the questionnaires (226 UNIT and 135 FMABC), 70% were female and 67% were White. The majority did not use medication for depression (90%), anxiety (81%), and stress management (91%). Regarding anxiety, it was found: absence in the traditional method and moderate anxiety in the active methodology (26% UNIT×13% FMABC) (p<0.001). Regarding quality of life, it was found to be better quality of life in the environment domain at FMABC (78.12%) versus 71.88% at the UNIT (p<0.001). There was no difference between the institutions in relation to depression and perceived stress, and in quality of lifethere was only a difference in the environmental domain (p<0.001). In relation to gender, stress was higher in females (93.7%) than males (79.6%) with p<0.001. CONCLUSION: Differences were recorded between the groups regarding anxiety, with a predominance in UNIT students (active methodology), and no differences were recorded in relation to depression, perceived stress, and quality of life in all domains, except for the environment domain, which was higher in the traditional methodology, although about one-third of participants used medication for anxiety/depression.

Transfusion of packed red blood cells in adults with sickle cell anemia treated at an emergency hospital

SUMMARY OBJECTIVE: The aim of this study was to analyze the prescription of packed red blood cells performed by emergency physicians for adults with sickle cell anemia. METHODS: Transfusions performed in adults with sickle cell anemia treated at an emergency service in São Bernardo do Campo, São Paulo Brazil, between January 2018 and January 2022 were evaluated. For data comparison, the chi-square2 test was used. The significance level adopted was 5%. RESULTS: A total of 114 transfusions were performed. The mean age was 41.8±16.4 years, and pretransfusion hemoglobin was 6.1±1.23 g/dL. Regarding the indication, the adequacy of transfusions performed in symptomatic individuals was significantly higher compared to asymptomatic individuals (100% vs. 3.9%, p<0.001). Symptomatic individuals received excessive volumes of packed red blood cells less frequently than asymptomatic individuals (17.5% vs. 56.9%, p<0.001). The filtered subtype, indicated for sickle cell anemia, was prescribed in only a quarter of the patients. However, non-indicated subtypes were frequently prescribed. CONCLUSION: This study found low adequacy in the indication and calculation of the transfusion volume of packed red blood cells in asymptomatic individuals. Few patients received filtered red blood cells, resulting in increased risks of transfusion reactions. On the contrary, non-indicated subtypes were prescribed in a quarter of transfusions, which resulted in higher costs and delay in receiving packed red blood cells.

Homocysteine concentrations in overweight children and adolescents

SUMMARY OBJECTIVE: The aim of this study was to describe homocysteine concentrations in overweight and obese children and adolescents and relate them to blood pressure levels, renal function, and insulin resistance. METHODS: This is a cross-sectional and observational study with 64 overweight children and adolescents (mean age: 11.6±3.5 years) in outpatient follow-up. The following parameters were evaluated: body mass index z-score, waist-to-height circumference ratio, pubertal stage, blood pressure, serum homocysteine, glycemia, insulin, lipid profile, renal function, high-sensitivity C-reactive protein, microalbuminuria, and creatinuria. Statistical analysis: analysis of variance and logistic regression (dependent variable: homocysteine) (p<0.05). RESULTS: The mean body mass index z-score was 2.9±1.1. The mean homocysteine concentrations were 8.6±2.2 μmol/L (10th and 90th percentiles: 6.6 and 11.2 μmol/L, respectively), with no difference when compared with children with severe obesity and obesity/overweight (p=0.431). High values of waist-to-height ratio (93.8%), systolic blood pressure (18.8%), diastolic blood pressure (12.5%), glycemia (4.7%), low-density lipoprotein cholesterol (31.1%), triglycerides (35.9%), non-high-density lipoprotein cholesterol (34.4%), and microalbuminuria (21.9%) were obtained. The mean glomerular filtration rate was 122.9±24.6 mL/min/1.73 m². Homocysteine concentrations were not associated with any of the studied variables (R²=0.095). CONCLUSION: Homocysteine concentrations in overweight children and adolescents (mean 8.6±2.2 μmol/L) were not associated with body mass index z-score, blood pressure, renal function, and insulin resistance.

Vitamin D deficiency in bedridden elderly people at home

SUMMARY OBJECTIVE: The aim of this study was to evaluate serum 25(OH)D concentrations in the homebound elderly people and relate them to level of dementia, nutritional risk, and route of dietary administration. METHODS: This is a cross-sectional study involving 207 bedridden elderly people assisted by the Home Care Service in the city of Santo André - SP, from June to December 2016. The following factors were evaluated: dietary intake of vitamin D, arm circumference, triceps skin fold thickness, calf circumference, nutritional risk by Mini-Nutritional Assessment, level of dementia by the adapted Clinical Dementia Rating questionnaire, and laboratory tests such as serum concentrations of 25(OH)D, ultrasensitive C-reactive protein, alkaline phosphatase, serum calcium, and parathormone. RESULTS: The mean age of the elderly people was 81.6 (9.2) years. Deficiency of 25(OH)D was observed in 76.3% of the elderly people. There was an inverse correlation between serum concentrations of 25(OH)D: parathormone (r=-0.418, p<0.001) and alkaline phosphatase (r=-0.188, p=0.006) and a direct correlation with serum calcium (r=-0.158, p=0.022). Logistic regression showed that vitamin D deficiency was directly and independently associated with oral feeding (odds ratio 7.71; 95%CI 2.91-20.40). CONCLUSION: Bedridden households showed high prevalence of vitamin D deficiency without association with nutritional risk and level of dementia. Oral diet was associated with vitamin D deficiency, possibly due to low consumption of source foods.

Serum amyloid A in children and adolescents: association with overweight and carotid intima-media thickness

ABSTRACT Objective To compare serum amyloid A concentrations between overweight and eutrophic children and adolescents and to relate it to lipid profiles, glucose tolerance, and carotid intima-media thickness. Methods One hundred children and adolescents (mean age: 10.8±3.16 years) were included and divided into two groups: overweight and non-overweight. The following were evaluated: Z-score body mass index, carotid intima-media thickness, lipid metabolism biomarkers (lipid profile and apolipoproteins A1 and B), inflammatory biomarkers (ultra-sensitive C-reactive protein and serum amyloid A), and glucose homeostasis model assessment of insulin resistance. Results The groups were homogeneous in age, sex, and pubertal stage. Higher levels of triglycerides, apolipoprotein B, homeostasis model assessment of insulin resistance, ultrasensitive C-reactive protein, serum amyloid A, and carotid intima-media thickness were observed in the overweight group. In the multivariate analysis, age (OR=1.73; 95%CI: 1.16-2.60, p=0.007), Z-score body mass index (OR=3.76; 95%CI: 1.64-8.59, p=0.002), apolipoprotein-B (OR=1.1; 95%CI: 1.01-1.2, p=0.030), and carotid intima-media thickness (OR=5.00; 95%CI: 1.38-18.04, p=0.014) were independently associated with serum amyloid A levels above the fourth quartile of the studied sample (>9.4mg/dL). Conclusion Overweight children and adolescents had higher serum amyloid A concentrations than eutrophic children. There was an independent association between higher concentrations of serum amyloid A and Z-score, body mass index, apolipoprotein B, and carotid intima-media thickness, indicating the importance of this inflammatory biomarker in identifying the early risk of atherosclerosis.

Neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios of overweight children and adolescents

SUMMARY OBJECTIVE: This study aimed to compare neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio of overweight children and adolescents with the eutrophic ratios and to verify whether these ratios are associated with age, inflammation, Z-score of body mass index, and waist-to-height ratio. METHODS: This is a cross-sectional study involving 64 overweight and 106 eutrophic children and adolescents. Data on weight, height, and waist circumference (body mass index and waist-to-height ratio), blood count (neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio), and high-sensitivity C-reactive protein were collected. RESULTS: The mean age of participants was 8.4±3.2 years. The ratios did not differ between the overweight and non-overweight groups. The platelet-to-lymphocyte ratio has shown a direct and independent association with body mass index (p=0.031) and waist-to-height ratio (p=0.018), a fact not observed for neutrophil-to-lymphocyte ratio. The ultrasensitive C-reactive protein level was higher in the obesity group (p=0.003). Both ratios had a direct and independent association with age. CONCLUSION: The ratios did not differ between the overweight and non-overweight groups. There was a direct and independent association of platelet-to-lymphocyte ratio with overweight, not observed in neutrophil-to-lymphocyte ratio. The ratios have significantly increased according to the age of the participants.

Cow's milk allergy immunoglobulin E-mediated: intake of proteins and amino acids

SUMMARY OBJECTIVE: Children with cow's milk allergy may be at nutritional risk due to the lower intake of nutrients, such as protein, calcium, and vitamin A, which are present in cow's milk. The objective was to evaluate children's diets with Children with cow's milk allergy compared with healthy controls as well as to compare the intake of proteins and amino acids from the diet followed by Children with cow's milk allergy who consume special infant formula or plant-based dairy alternatives with Children with cow's milk allergy who do not consume special infant formula or plant-based dairy alternatives. METHODS: Through a cross-sectional controlled study, the dietary intake of 57 children (27 with immunoglobulin E-mediated Children with cow's milk allergy and 30 healthy controls) was evaluated. Using 24-h nutritional recalls, the total energy intake value, macronutrients, and amino acids were calculated. RESULTS: No statistically significant difference was found between the Children with cow's milk allergy group and healthy controls for the intake of proteins and amino acids. However, the Children with cow's milk allergy do not consume special infant formula or plant-based dairy alternatives group had a lower protein (g/kg) and branched-chain amino acid (mg/kg) intake than the Children with cow's milk allergy consume special infant formula or plant-based dairy alternatives group. CONCLUSIONS: The Children with cow's milk allergy group achieved the recommendations for the intake of proteins and amino acids compared to the healthy control group. However, the Children with cow's milk allergy do not consume special infant formula or plant-based dairy alternatives group had a lower intake of protein (g/kg) and branched-chain amino acid (mg/kg) than the Children with cow's milk allergy consume special infant formula or plant-based dairy alternatives group.

Association between acanthosis nigricans and overweight with hypertension in children and adolescents from low-income families

SUMMARY OBJECTIVE: This study aimed to describe the prevalence of acanthosis nigricans and high blood pressure in children and adolescents from low-income families, and to verify the association of elevated blood pressure with nutritional status and the presence of acanthosis nigricans. METHODS: This is a cross-sectional and controlled study with 232 children and adolescents from an institution for low-income families. Pubertal stage, body mass index Z-score, waist-to-height circumference ratio (increased waist-to-height circumference ratio >0.5), the presence of acanthosis nigricans, and blood pressure were assessed. RESULTS: The prevalence of excess weight and the change in waist-to-height circumference ratio was 37.9%. Acanthosis nigricans and increased blood pressure occurred in 20.3 and 34.8%, respectively. The prevalence of acanthosis nigricans and hypertension was higher in individuals with excess weight (p<0.001; p<0.001) and with an increased waist-to-height circumference ratio (p=0.009; p<0.001). Logistic regression showed a significant and independent association of body mass index Z-score (OR 2.35; 95%CI 1.52-3.65; p<0.001) and the presence of acanthosis nigricans (OR 2.43; 95%CI 1.12-5.23; p=0.023) with elevated blood pressure. CONCLUSION: Acanthosis nigricans and elevated blood pressure occurred in one-fifth and one-third of the individuals in an institution for children from low-income families. Overweight and the presence of acanthosis nigricans increased the risk of high blood pressure more than twofold.

Iron deficiency anemia in infants in Sousa (PB), Brazil: an association with nutritional status

SUMMARY OBJECTIVE The aim of this study was to describe the prevalence of anemia and iron deficiency anemia (IDA) in infants and verify the association of iron deficiency with nutritional status. METHODS This cross-sectional and observational study included 104 infants aged between 7 and 9 months, assisted from August to September 2021 by the Family Health Strategy program in Sousa municipality (Paraíba, Brazil). Clinical and anthropometric data were collected, and a 24-h food recall questionnaire was applied using the DietPro software (version 5.0) in order to verify food consumption and assess iron intake. Variables associated with iron deficiency (p<0.05) were analyzed using multiple logistic regression. RESULTS Anemia and IDA were observed in 40.4% and 19.2% of infants, respectively. Only one infant was taking prophylactic supplementation (ferrous sulfate). Infants with IDA presented reduced hemoglobin (p<0.001) and ferritin (p<0.001) and increased Z-scores of body mass index-for-age (Z-BMI) (p=0.027), weight-for-height (p=0.007), and weight-for-age (p=0.032). All Z-scores were inversely correlated with ferritin (Z-BMI [rho: -0.37; p<0.001], weight-for-height [rho: -0.37; p<0.001], and weight-for-age [rho: -0.29; p=0.002]). Ferritin was also directly correlated with daily iron intake (rho: 0.22; p=0.018). Finally, multiple logistic regression showed a significant and direct association of iron deficiency with weight-for-height Z-score (odds ratio: 2.86; 95% confidence interval: 1.38-5.64; p=0.004). CONCLUSION About 60% of infants presented anemia or IDA. Iron deficiency was associated with the weight-for-height Z-score, showing the vulnerability of infants during the introduction of complementary feeding.

Childhood obesity: an ecological perspective

Abstract Objective: To describe the participation of the environment in the childhood obesity epidemic, since childhood obesity currently represents a great challenge, with high prevalence worldwide, including in Brazil. Data source: Survey of articles published in the last 10 years in PubMed, evaluating the interface between the environment and childhood obesity. Data synthesis: Recent studies show that the environment is very important in the etiopathogenesis of obesity and its comorbidities. Therefore, factors such as air pollution, exposure to chemical substances that interfere with the metabolism, excessive consumption of ultra-processed foods, changes in the intestinal microbiota, and sedentary lifestyle are associated with increased obesity, insulin resistance, type 2 diabetes, and changes in lipid metabolism. These factors have a greater impact on some stages of life, such as the first thousand days, as they affect the expression of genes that control the adipogenesis, energy expenditure, and the mechanisms for hunger/satiety control. Conclusions: Environmental aspects must be taken into account in the prevention and treatment of childhood obesity, both from the individual and the population point of view, with adequate and comprehensive public health policies.

Relationship between body mass index and waist-to-height ratio in childhood

SUMMARY OBJECTIVE: To evaluate whether there is an association between the body mass index z-score and waist-to-height ratio of children and adolescents. METHODS: This was a cross-sectional study conducted in a school in Santo André, SP, between June and August 2019. Body mass index was measured for all participants, adopting the z-score cutoff of +2 recommended by the World Health Organization. The waist-to-height ratio was determined in children over two years of age and considered abnormal when ≥0.5. The qualitative variables are presented as absolute numbers and percentages. To compare qualitative data, we used the χ2 test or Fisher's exact test. Pearson's test was applied to assess the correlation between BMI and waist-to-height ratio. The level of significance adopted was 5%. RESULTS: The body mass index was calculated for 518 children and the waist-to-height ratio for 473 children. Regarding body mass index, 60.6% of the participants had normal weight, 3.1% were underweight, and 36.3% were overweight. overweight (24.7%) and obesity (22.7%) were more prevalent in adolescents. The waist-to-height ratio was abnormal in 50.5% of the sample. There was an increasing association between body mass index and waist-to-height ratio with age, according to the Pearson correlation coefficients for the age groups <5 years (r=0.459; p<0.001), 5 to 10 years (r=0.687; p<0.001) and >10 years (r=0.805; p<0.001). CONCLUSION: There was a significant correlation between body mass index and waist-to-height ratio. This association was higher in adolescents. The waist-to-height ratio is easy to apply and may be useful as a predictor of cardiometabolic risk.

Risk factors for the lack of adherence to breastfeeding

SUMMARY OBJECTIVE: To evaluate the prevalence of breastfeeding in a metropolitan region in Brasil and to identify factors influencing the lack of adherence to exclusive breastfeeding for 6 months and total breastfeeding for 2 years. METHODS: In this cross-sectional study, demographic and socioeconomic characteristics of mothers and children in pediatric outpatient clinics were analyzed. Logistic regression was performed using the backward stepwise method to analyze factors associated with the lack of breastfeeding compliance. RESULTS: In total, 385 mothers who visited the pediatric outpatient clinics were included. Among the mothers, 38.44% reported exclusive breastfeeding for >6 months and 22.6% reported total breastfeeding for 2 years or more. The predictive factors for the lack of adherence to exclusive breastfeeding for 6 months included single mothers (OR=1.976; 95%CI 1.245-3.135; p=0.004), use of a pacifier (OR=2.25; 95%CI 1.436-3.524; p<0.001), and low birth weight (OR=2.21; 95%CI 1.192-4.102; p=0.012). Predictive factors for the lack of adherence to total breastfeeding for 2 or more years included use of a pacifier (OR=4.82; 95%CI 2.722-8.54; p<0.001), planned pregnancy (OR=0.51; 95%CI 0.305-0.875; p=0.014), and breastfeeding in the first hour of life (OR=0.36; 95%CI 0.208-0.641; p<0.001). CONCLUSIONS: The prevalence of exclusive breastfeeding for 6 months and total breastfeeding for 2 years or more was insufficient in the studied population. Several factors were associated with the lower duration of exclusive breastfeeding and total breastfeeding. The use of a pacifier and no breastfeeding in the first hour were preventable factors associated with both modalities.

Percepções de adolescentes a respeito do impacto da gravidez em suas relações sociais / Moral conflicts in physiotherapy practice: perception of physiotherapists and students

A maioria das gestantes adolescentes, mesmo desejando a sua gravidez e sendo asseguradas por políticas públicas, enfrentam dificuldades no relacionamento com a família e com o parceiro, tendendo a sofrer com a desestruturação de sua vida. Dessa forma, o trabalho tem como objetivo compreender as percepções das adolescentes primigestas a respeito do impacto da gravidez em suas relações sociais. Trata-se de um estudo qualitativo pautado no referencial teórico do Pensamento Complexo de Morin. O estudo foi realizado com 17 adolescentes primigestas acompanhadas no Ambulatório de Pré-Natal de Adolescentes do Centro de Saúde Escola, Santo André, Estado de São Paulo, Brasil. Os dados foram coletados por meio da Técnica de Entrevista e trabalhados por meio de Análise de Conteúdo. Como resultados foram obtidas três categorias - A reação do parceiro em relação à gravidez, A compreensão da família com relação a gravidez e A mudança na rede social após a gravidez. Muitas adolescentes relacionam a gravidez a idealização de se tornar adulta e respeitada pelo fato de se tornar mãe. Já os parceiros nem sempre possuem este sonho de ser pai e manter uma família. Já a família, permanece como primeira opção de escolha no apoio do casal de adolescente, porém algumas gestantes não demonstraram ter liberdade suficiente para dialogar com seus familiares. Dessa forma, nota-se que a gravidez na adolescência gera transformações psicossociais difíceis, como a evasão escolar e o afastamento do círculo social, evidenciando sofrimentos por parte das adolescentes.

Most pregnant teenagers, even wanting their pregnancy and being insured by public policies, face difficulties in their relationships with their family and partner, tending to suffer from the disruption of their lives. Thus, this work aims to understand the perceptions of primiparous teenagers about the impact of pregnancy on their social relationships. This is a qualitative study based on the theoretical framework of Morin's Complex Thinking. The study was carried out with 17 primiparous adolescents followed up at the Adolescent Prenatal Outpatient Clinic of the School Health Center in Santo André, State of São Paulo, Brazil. Data were collected through the Interview Technique and processed through Content Analysis. As a result, three categories were obtained - the partner's reaction to the pregnancy, the family's understanding of pregnancy, and the change in their social network after pregnancy. Many teenagers relate pregnancy to the idealization of becoming an adult and respected for the fact of becoming a mother. Partners do not always have this dream of being a father and keeping a family. The family, on the other hand, remains the first choice in the support of teenage couples, but some pregnant women did not demonstrate enough freedom to dialogue with their family members. It is noticed that teenage pregnancy generates social changes, especially with regards to school dropouts and social withdrawal. Thus, it is noted that teenage pregnancy generates difficult biopsychosocial transformations, such as dropping out of school and moving away from their social circle, demonstrating a suffering on the part of the teenagers.

Evaluation of the measurement properties of the Brazilian version of two quality-of-life questionnaires in food allergy - for children and their parents / Avaliação das propriedades de medida da versão brasileira de dois questionários de qualidade de vida em alergia alimentar - para crianças e seus pais

Abstract Objective: To evaluate the psychometric properties of the Brazilian version of health-related quality-of-life questionnaires of children with food allergy and their parents. Methods: The translation and cultural adaptation processes were previously performed, according to the method proposed by the World Health Organization. After this stage, the questionnaires were applied to 201 parents of children under 6 years of age with food allergy. The assessment of the psychometric properties included: evaluation of the internal consistency by Cronbach's alpha coefficient; of the reproducibility by the intraclass correlation coefficient between test and retest; and of the construct, using Spearman's correlation coefficient, comparing the obtained scores with those of generic questionnaires that evaluate health-related quality of life. Results: The means of the obtained scores were 2.44 and 3.35, for the children and their parents, respectively. Cronbach's alpha coefficients were 0.85 and 0.91, respectively, which showed good internal consistency of the tools. The intraclass correlation coefficients between test and retest were 0.87 and 0.84 for children and their parents, respectively, showing good reproducibility for both questionnaires. The correlation between the specific and the generic questionnaires was significant (−0.27 for the children, −0.64 for their parents, p < 0.05). Conclusions: The specific questionnaires to evaluate the health-related quality of life of children with food allergy and of their parents were satisfactorily validated to be used in Brazil.

Resumo Objetivo: Avaliar as propriedades psicométricas da versão brasileira dos questionários de qualidade de vida relacionada à saúde de crianças com alergia alimentar e de seus pais. Método: Os processos de tradução e adaptação cultural foram feitos previamente, de acordo com o método proposto pela Organização Mundial da Saúde. Após essa etapa, os questionários foram aplicados a 201 pais de crianças menores de 6 anos com alergia alimentar. A avaliação das propriedades psicométricas incluiu: avaliação da consistência interna, pelo coeficiente alfa de Cronbach; da reprodutibilidade, pelo coeficiente de correlação intraclasse entre teste e reteste; e do constructo, empregou-se o coeficiente de correlação de Spearman, comparando os escores obtidos com os de questionários genéricos que avaliam a qualidade de vida relacionada à saúde. Resultados: As médias dos escores obtidos foram 2,44 e 3,35, para as crianças e seus pais, respectivamente. Os coeficientes alfa de Cronbach foram 0,85 e 0,91, respectivamente, o que demonstrou boa consistência interna dos instrumentos. Os coeficientes de correlação intraclasse entre os testes e os retestes foram 0,87 e 0,84, para crianças e seus pais, respectivamente, demonstraram boa reprodutibilidade para ambos os questionários. A correlação entre os questionários específicos e genéricos foi significante (−0,27 para as crianças; −0,64 para os pais; p < 0,05). Conclusões: Os questionários específicos para avaliar a qualidade de vida relacionada à saúde de crianças com alergia alimentar e de seus pais foram satisfatoriamente validados para uso no Brasil.

Alergia alimentar ao leite de vaca e ovo mediadas por IgE: sugestões de receitas termicamente testadas / IgE-mediated food allergy to cow's milk and egg: baked recipe suggestions

Objetivo: Cerca de 50% dos indivíduos com alergia ao leite de vaca e ao ovo podem tolerar esses alimentos em sua forma termicamente tratada. O consumo desses alimentos, mesmo que termicamente tratados, pode ampliar a variedade da dieta de crianças com alergia alimentar. O presente artigo tem como objetivo propor receitas culinárias com leite de vaca e ovo tratados termicamente para serem usadas em teste de provocação oral. Métodos: Alguns critérios foram adotados para elaboração das receitas: quantidade de proteína alergênica testada por porção (leite de vaca - 1,3 g; ovo - 2,0 g), tempo (30 minutos), temperatura de cocção (180 °C), os ingredientes que devem compor a receita (farinha de trigo como principal ingrediente), volume final da porção a ser oferecida, além de questões de ordem prática relacionadas ao preparo e oferta das preparações. Resultados: No total foram desenvolvidas dez receitas termicamente tratadas, sendo cinco com leite de vaca (três receitas de bolinho ­ básica, sem açúcar e sem ovo de galinha; duas receitas de tortinha salgada ­ básica e sem ovo de galinha) e cinco com ovo de galinha (três receitas de bolinho ­ básica, sem açúcar, e sem leite de vaca; duas receitas de tortinha salgada ­ básica e sem leite de vaca). Conclusão: É de extrema importância que o teste de provocação oral seja realizado de maneira rotineira e com preparações adequadas e padronizadas, e, em nosso conhecimento, esse é o primeiro estudo nacional que propõe várias receitas tratadas termicamente para auxiliar serviços especializados que atendem pacientes com alergia alimentar.

Objective: About 50% of individuals with cow's milk and egg allergies can tolerate these foods in their baked form. The consumption of these foods, even if baked, may expand the variety of the diet of children with food allergy. This article aims to propose recipes with baked milk and egg to be used in an oral food challenge. Methods: Some criteria were adopted for preparing the recipes: amount of allergenic protein tested per serving (cow's milk: 1.3 g; egg: 2.0 g), time (30 min), oven temperature (180 °C), the ingredients that should compose the recipe (wheat flour as the main ingredient), final volume of the serving to be provided, in addition to practical questions related to the preparation and provision of the recipes. Results: In total, ten baked recipes were developed, five with cow's milk (three cupcake recipes: regular, with no sugar and no egg; two savory muffin recipes: regular, with no egg) and five with egg (three cupcake recipes: regular, with no sugar and no cow's milk; two savory muffin recipes: regular, with no cow's milk). Conclusion: It is extremely important that the oral food challenge is performed routinely and with adequate and standardized recipes. To our knowledge, this is the first national study in Brazil that proposes several baked recipes to assist specialist services that treat patients with food allergy.

Evaluation of treatment of the exacerbation of asthma and wheezing in a pediatric emergency department

SUMMARY OBJECTIVES: To evaluate the treatment of wheezing and exacerbation of asthma in a pediatric emergency unit (ED), comparing it to that recommended by the guidelines for this purpose. METHODS: Descriptive cross-sectional study through medical records survey of children and adolescents (0-15 years of age) who received medication for wheezing or asthma exacerbation from January to April 2015 in the ED. The selected treatment was compared to that recommended by the guidelines, being analyzed the variables related to the medication (number and dose of short-acting β2 agonist, associated or not with anticholinergic, oral or parenteral corticosteroid) and the length of stay in ED (≤1 h, ≥8 h and hospital admission). RESULTS: One-thousand eleven patients were selected with 56.7% between 3 and 15 years and 56% male. Although the selected drugs were in accordance with what was recommended, errors were observed in relation to dose, drug of choice, and method and time of use with the most frequent finding being incorrect dose (short-acting β2 agonist: 66% and ipratropium bromide: 95.2%). CONCLUSION: The level of use of the measures recommended by the guidelines was low but compatible with other studies, leading to an increased risk of treatment failure and higher costs. Despite wide dissemination, the established concepts have not been sufficiently incorporated into clinical practice, suggesting the need for more effective educational actions for this process to occur.

RESUMO OBJETIVOS: Avaliar o tratamento da sibilância e da exacerbação da asma em unidade de emergência pediátrica (DE), comparando-o ao recomendado pelas diretrizes para esse fim. MÉTODOS: Estudo descritivo transversal, por meio do levantamento de prontuários de crianças e adolescentes (0 - 15 anos de idade) que receberam medicação para sibilância ou exacerbação da asma, no período de janeiro a abril de 2015, em DE. O tratamento empregado foi comparado ao preconizado pelas diretrizes sendo analisadas as variáveis referentes à medicação (número e dose de β2 agonista de curta ação, associado ou não a anticolinérgico, corticosteroide oral ou parenteral) e ao tempo de permanência na DE (≤1 h, ≥8 h e internação hospitalar). RESULTADOS: Foram selecionados 1011 pacientes, 56,7% com idades entre 3 e 15 anos e 56 % do sexo masculino. Embora os fármacos utilizados estivessem de acordo com o preconizado, foram observados erros com relação a dose, droga de escolha, forma de utilização, tempo de uso, sendo dose incorreta o achado mais frequente (β2 agonista de curta ação: 66% e brometo de ipratrópio: 95,2%). CONCLUSÃO: O nível de utilização das medidas recomendadas pelas diretrizes foi baixo e compatível com outros estudos, levando a risco aumentado de falha no tratamento e maior custo. Apesar da ampla divulgação, os conceitos estabelecidos não são suficientemente incorporados à prática clínica, sugerindo a necessidade de ações educativas mais efetivas para que isso ocorra.

Lipid profile of pediatric patients with chronic rheumatic diseases - a retrospective analysis

SUMMARY AIM To describe the prevalence of dyslipidemia in children and adolescents with autoimmune rheumatic diseases (ARDs), particularly juvenile idiopathic arthritis (JIA), juvenile systemic lupus erythematosus (jSLE), and juvenile dermatomyositis (JDM). METHODS Retrospective cross-sectional study conducted in the pediatric rheumatology outpatient clinic. We evaluated 186 children and adolescents between the ages of 5 and 19 years. The medical records were reviewed for the following data: demographic and clinical features, disease activity, and lipid profile (triglycerides (TG), total cholesterol (TC), low density lipoprotein (LDL-C), high density lipoprotein (HDL-C) and very low density lipoprotein (VLDL-C)). In addition, non-HDL cholesterol was calculated as TC minus HDL-C. The cut-off points proposed by the American Academy of Pediatrics were used to classify the lipid profile. RESULTS Dyslipidemia was observed in 128 patients (68.8%), the most common being decreased HDL-C (74 patients, 39.8%). In the JIA group there was an association between the systemic subtype and altered LDL-C and NHDL-C, which demonstrated a more atherogenic profile in this subtype (p=0.027 and p=0.017, respectively). Among patients with jSLE, the cumulative corticosteroid dose was associated with an increase in LDL-C (p=0.013) and with a decrease in HDL-C (p=0.022). CONCLUSION Dyslipidemia is common in children and adolescents with ARDs, especially JIA, jSLE, and JDM, and the main alteration in the lipid profile of these patients was decreased HDL-C.

RESUMO OBJETIVO Descrever a prevalência de dislipidemias em crianças e adolescentes com doenças reumáticas autoimunes (Drai), em particular artrite idiopática juvenil (AIJ), lúpus eritematoso sistêmico juvenil (Lesj) e dermatomiosite juvenil (DMJ). MÉTODOS Estudo transversal retrospectivo realizado no ambulatório de reumatologia pediátrica. Foram avaliados 186 crianças e adolescentes com idades entre 5 e 19 anos. Foram coletados dos prontuários dados demográficos, clínicos, atividade de doença e perfil lipídico (triglicérides (TG), colesterol total (CT) e frações LDL-c (low density lipoprotein); HDL-c (high density lipoprotein) e VLDL-c (very low density lipoprotein). Foi também calculada a fração não HDL do colesterol (CT-NHDL -c). Para classificação do perfil lipídico, foram adotados os pontos de corte propostos pela American Academy of Pediatrics. RESULTADOS A dislipidemia foi observada em 128 pacientes (68,8%), sendo a mais comum a diminuição do HDL-c em 74 (39,8%). No grupo AIJ houve uma associação entre o subtipo sistêmico com alteração de LDL-c e NHDL-c, mostrando um perfil mais aterogênico neste subtipo (p=0,027 e 0,017, respectivamente). Em relação aos pacientes com Lesj, podemos observar que a dose cumulativa de CTC teve associação com o aumento do LDL-c (p=0,013) e com a diminuição do HDL-c (p=0,022). CONCLUSÃO A dislipidemia é frequente em crianças e adolescentes com Drai, em especial, AIJ, Lesj e DMJ, e a principal alteração no perfil lipídico desses pacientes foi a diminuição do HDL-c.
