Résumé

Abstract Objective: Perfume (Parfum) or fragrance is a natural or synthetic cosmetic ingredient added to emit a pleasant aroma or to improve the odor of a cosmetic formula. It is a mixture of substances, not revealed by the manufacturer, which may contain ingredients with allergenic potential, endocrine disruptors, and other possible harmful effects on human health. This study aims to analyze children's cosmetics labels to assess the presence of Perfume. Methods: The researchers randomly visited points of sale in Curitiba, the capital of a southern Brazilian state; in order to catalog the largest possible number of children's cosmetics items. Results: 398 children's cosmetics were analyzed and found Parfum on 295 (74.1 %) of the labels, including 90.4 and 79,1 % of the shampoos and wet wipes, respectively. Conclusion: Exposure of children's skin to fragrances can lead to local side effects such as allergies, but also to systemic effects, and the lack of knowledge of the general population and health professionals about its possible deleterious effects emphasizes the importance of changes in the regulation of cosmetics aiming to reduce the use of this ingredient.

Résumé

Abstract Objective: To evaluate the pH value of children's antibacterial soaps and syndets used in children's baths and verify whether there is information regarding pH on the product label. Methods: Quantitative, cross-sectional, analytical observational study that included ninety soap samples, both in bar and liquid presentations, as follows: 67 children's soap (group 1), 17 antibacterial soaps (group 2), and 6 syndets (group 3). Each sample had its pH measured after 1% dilution. In addition to descriptive statistics, the Pearson-Yates chi-squared test and Student's t-tests were applied, considering the minimal significance level of 5%. The Wilcoxon-Mann-Whitney test, Fisher's exact test, and the Kruskal-Wallis test were used for inferential statistics. Results: The pH levels varied considerably between liquid and bar presentations, with lower levels (4.4-7.9) found for the liquids (p < 0.05). Syndets showed pH levels close to the ideal (slightly acid) and the antibacterial soaps showed the highest pH levels (up to 11.34) (p < 0.05). Only two of the soaps included in the study had information about their pH levels on the product packaging. Conclusions: Knowledge of the pH of children's soap by doctors and users is important, considering the great pH variability found in this study. Moreover, liquid soaps, and especially syndets, are the most recommended for the sensitive skin of neonates and infants, in order to guarantee skin barrier efficacy.


Resumo Objetivos: Avaliar o pH dos sabonetes infantis, antibacterianos e sindets (syntetic detergents) habitualmente usados em crianças, bem como verificar se há no rótulo desses produtos informação sobre seu pH. Métodos: Estudo observacional, analítico, transversal e quantitativo, que incluiu 90 sabonetes nas apresentações em barra e líquida, 67 infantis (grupo 1), 17 antibacterianos (grupo 2) e 6 sindets (grupo 3). Procedeu-se à mensuração do pH das amostras após diluição a 1%. Além da estatística descritiva, foram usados os testes de qui-quadrado Persons/Yates e t de Student, com nível de significância mínimo de 5%. Para a estatística inferencial, foram usados os testes de Wilcoxon-Mann-Whitney, exato de Fisher e Kruskal-Wallis. Resultados: O pH variou consideravelmente entre as formas líquida e em barra, com pHs menores (de 4,4 a 7,9) nos líquidos (p < 0,05). Os sindets mostraram pHs próximos ao ideal (levemente ácidos) e os antibacterianos apresentaram os maiores pHs (até 11,34) (p < 0.05). Apenas dois dos sabonetes analisados apresentavam no rótulo a indicação do pH. Conclusões: A observação do pH dos sabonetes infantis pelos médicos e usuários é importante, haja vista a grande variabilidade de valores de pH encontrados. Além disso, os sabonetes líquidos, e especialmente os sindets, são os mais recomendados para uso em recém-nascidos e lactentes com pele sensível, de forma a garantir a eficácia da barreira cutânea.

Résumé

Não há consenso sobre quais são os valores ideais da vitamina D em crianças saudáveis. Porém, níveis séricos altos ou baixos parecem ter influência na fisiopatologia das doenças alérgicas. Há dados na literatura atual que demonstram os potenciais efeitos da vitamina D em aumentar a atividade dos peptídeos antimicrobianos e suprimir a resposta inflamatória, apontando uma relação inversa entre os níveis de vitamina D e a gravidade da dermatite atópica. O objetivo do presente trabalho foi revisar artigos publicados sobre a relação entre níveis séricos de vitamina D e dermatite atópica, uma vez que a vitamina D tem sido implicada em várias ações imunomoduladoras e alguns estudos têm descrito sua influência na gravidade da dermatite atópica, porém com resultados conflitantes. Este estudo baseou-se em revisão de artigos originais, artigos de revisão e consensos publicados nos últimos 10 anos, obtidos a partir da pesquisa dos termos “vitamin D” e “atopic dermatitis”, nos bancos de dados online. Concluímos que a suplementação da vitamina D pode trazer benefícios no tratamento da dermatite atópica. No entanto, mais pesquisas são necessárias para determinar se existe alguma relação entre os níveis de vitamina D e a gravidade da dermatite atópica.


There is no consensus about optimal values of vitamin D in normal children. However, high or low serum levels seem to influence the pathophysiology of allergic diseases. There is evidence supporting the potential effects of vitamin D on increasing the activity of antimicrobial peptides and suppressing the inflammatory response, indicating an inverse relationship between vitamin D levels and the severity of atopic dermatitis. Our objective was to review published articles on the relationship between serum vitamin D levels and atopic dermatitis, as vitamin D has been implicated in several immunoregulatory actions, and some studies have reported an influence on the severity of atopic dermatitis, with conflicting results. The present study reviewed original articles, review articles, and consensus documents published in the past 10 years, retrieved in online databases using the keywords “vitamin D” and “atopic dermatitis.” We conclude that vitamin D supplementation may be beneficial in the treatment of atopic dermatitis. However, more research is needed to determine whether there is any relationship between vitamin D levels and atopic dermatitis severity.
