Sociodemographic, clinical, epidemiological and care aspects of children and adolescents treated for retinoblastoma in Brazil: a cross-sectional study / Aspectos sociodemográficos, clínicos, epidemiológicos e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil: estudo transversal

Introduction: Retinoblastoma greatly impacts the affected children and adolescents and their families. Epidemiological approaches to this form of cancer in Brazil are scarce, and this gap motivated this study. Objectives:This study aimed to describe the sociodemographic, clinical, epidemiological, and care characteristics of children and adolescents treated for retinoblastoma in Brazil and analyze whether there is any association between them. Methods: It is a cross-sectional, descriptive-analytical study, carried out with accompanying family members of children and adolescents treated for retinoblastoma in Brazil, sampled by snowball sampling, via a web survey, based on a semi-structured questionnaire elaborated by the authors, shared on social media. Results: The children and adolescents were represented by 129 accompanying family members from the five largest regions of Brazil. Low education level, housewifery, and low family income were associated with exclusive care provided by the Unified Health System, while low family income was associated with the use of ocular prosthesis post retinoblastoma. Conclusion: The identified odds ratio indicated the importance of family members' sociodemographic aspects for the clinical, epidemiological and care outcomes of the children and adolescents treated. Public healthcare services were the most used for oncology care, which endorses the relevance of the Unified Health System for children, adolescents, and their family members who have been impacted by retinoblastoma in the country (AU)

Introdução: O retinoblastoma impacta sobremaneira as crianças, adolescentes e familiares acometidos. Abordagens epidemiológicas sobre tal câncer no Brasil são escassas, lacuna esta que motivou este trabalho. Objetivos: Os objetivos desse estudo foram descrever as características sociodemográficas, clínicas, epidemiológicas e assistenciais de crianças e adolescentes atendidos por retinoblastoma no Brasil e analisar se existe associação entre tais características. Métodos: Tratou-se de um estudo transversal, descritivo-analítico, realizado com acompanhantes familiares de crianças e adolescentes atendidos por retinoblastoma no Brasil, amostrados por snowball sampling, via web survey, a partir de um roteiro autoral semiestruturado, compartilhado em mídias sociais. Os dados foram analisados por meio de estatística descritiva e inferencial, com o auxílio do software Statistical Package for the Social Sciences. Resultados: As crianças e os adolescentes foram retratados por 129 acompanhantes familiares das cinco grandes regiões brasileiras. A escolaridade baixa, a ocupação do lar e a baixa renda familiar dos respondentes associaram-se ao atendimento exclusivo pelo Sistema Único de Saúde, sendo que a baixa renda familiar também associou-se ao uso de prótese ocular pós retinoblastoma. Conclusões: As razões de chances identificadas sinalizaram para a importância dos aspectos sociodemográficos dos familiares para os desfechos clínicos-epidemiológicos-assistenciais das crianças e dos adolescentes atendidos. Os serviços públicos foram os mais utilizados para a assistência oncológica, o que endossa a relevância do Sistema Único de Saúde para as crianças, adolescentes e familiares impactados pelo retinoblastoma no país (AU)

Relationship between Gene Polymorphisms in Interleukin-12B Promoter and Upper Gastrointestinal Disease Infected with Helicobacter Pylori in Children and Adolescent / 实用儿科临床杂志

Objective To investigate the relationship between the promoter of IL-12B gene polymorphism and the susceptibility and clinical features of chronic gastritis and duodenal ulcer with or without Helicobacter pylori(Hp) infection in children and adolescent.Methods Mucosal biopsies were obtained from 132 children and adolescent (patient group),including 100 children with chronic gastritis and 32 children with duodenal ulcer,undergoing an upper gastrointestinal endoscopy for dyspeptic symptoms.Biopsy specimens were stained with hematoxilin and eosin (HE),and gastritis was graded according to the Sydney system.Serology,urease test and histology were taken to assess Hp status.Genomic DNA was obtained from peripheral blood or gastric biopsies of patients and 102 healthy children as normal control group.The promoter of IL-12B +1188A/G gene polymorphism was genotyped by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and sequencing.The genotype distributions and allele frequencies were compared between the study group and the normal control group,and the association of genotypes with clinicopathological features was studied.IL-12B mRNA level expressions in gastric mucosa were confirmed by reverse transcription PCR biopsy-based tests.Results The genotype distributions and allele frequencies of IL-12B +1188A/G gene polymorphisms were similar in gastric upper gastrointestinal diseases and healthy subjects.The IL-12B +1188A/G gene polymorphisms were not associated with Hp status.IL-12B+1188A/G gene polymorphisms did not affect IL-12B mRNA level expressions and were not associated with the degree of antrum chronic inflammation.Conclusions These data suggest that IL-12B+1188A/G gene polymorphisms are not associated with susceptibility to chronic gastritis and duodenal ulcer in children and adolescent.
