O estudo tem como objetivo analisar os principais tipos de alimentos com potencial risco alergênico e descrever a prevalência da alergia causada por cada alimento estudado. Realizou-se uma revisão integrativa, utilizando os descritores alergia alimentar, estudos de prevalência e alérgenos, nos idiomas inglês, português e espanhol. Os critérios de inclusão foram artigos na íntegra que retratassem a temática da prevalência da alergia alimentar, publicados no período de 2011 a 2017. O estudo foi finalizado com 16 artigos. Leite de vaca e o ovo branco foram os alérgenos mais prevalentes nos últimos cinco anos. Vários foram os métodos utilizados para a identificação da alergia alimentar, que vem aumentando significativamente, nos últimos cinco anos. Dos métodos, os mais utilizados foram os questionários clínicos, teste cutâneo e determinação de IgE específica.
We report the first case of a child with 16p11.2 microduplication syndrome with increased fluid in the cisterna magna seen on magnetic resonance imaging (MRI). This finding may correspond to a Blake’s Pouch Cyst (BPC) or a Mega Cisterna Magna (MCM), being impossible to differentiate through image examination. The molecular duplication was diagnosed using chromosomal microarray analysis with single nucleotide polymorphism (SNP). We review the clinical and neuroimaging features in published case reports in order to observe the findings described in the literature so far and present a skull three-dimensional model to contribute to a better understanding. Despite the variable expressivity of the syndrome being well known, there is no case described in the available literature that mentions the association of 16p11.2 microduplication and the presence of BPC or MCM seen in neuroimaging exams. This finding may represent an extension of the phenotype not yet reported or may present itself as a coincidence in a child with various malformations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
