Analysis of pathogenic factors and clinical manifestations of 55 subjects with contact stomatitis / 口腔疾病防治

Objective @#To investigate the pathogenic factors and clinical manifestations of contact stomatitis, and to provide references for its clinical diagnosis and prevention. @*Methods@#The data of 55 subjects with contact stomatitis were analyzed retrospectively, including age, gender, pathogenic factors, type of lesions and site of occurrence.@*Results@#Among the 55 patients, contact stomatitis occurred at all ages, 19 were male, 36 were female, and the ratio of males to females was 1∶1.89. Among 55 patients, 78.18% (43/55) were caused by oral mucosal contact with dental materials: amalgam fillings accounted for 52.73% (29/55), metal crowns accounted for 9.09% (5/55), removable denture plastic bases accounted for 9.09% (5/55), resin fillings accounted for 5.45% (3/55), and alginate impression materials accounted for 1.82% (1/55); 21.82% (12/55) were caused by oral mucosal contact with food and daily necessities. The clinical manifestations of contact stomatitis include lichenoid reaction, erythema and erosion. The most common site of contact stomatitis was the cheek, followed by the tongue, and the lips, and the gingival and palatal areas were relatively rare. In the buccal mucosa, the incidence of lichenoid reaction was 55% (22/40), which was higher than that of erosion (20%) and erythema (25%), and the difference was statistically significant (P < 0.05). For tongue, lip, gingiva and palate, there was no significant difference in the incidence of the three lesion types（P > 0.05）.@*Conclusion@#Contact stomatitis occurred at all ages, and there are more female patients than males with contact stomatitis. Dental materials, especially metal and acrylic materials (such as the plastic base of removable dentures, resin fillings, adhesives, and self-setting plastics), are the main pathogenic factors. In buccal mucosa, the incidence of lichenoid reaction is higher.

Measuring the perception of quality physical education in Latin American professionals / Medindo a percepção de profissionais latino-americanos sobre a qualidade da educação física / Midiendo la percepción de profesionales latinoamericanos acerca de la Calidad de la Educación Física

Abstract An unsteady plan for curriculum development and supportive issues in physical education (PE) has created confusion among professionals. The purpose of this research is to investigate the factors perceived as important in the development of quality physical education (QPE) by professionals in Latin American (LA) countries. A questionnaire consisting of 24 items based on QPE was responded by 468 professionals collected from 6 LA cities. An exploratory factor analysis (EFA) of the 24 items using ML extraction and direct oblimin rotation were applied, and the retained 17 items were clustered in a three factor solution referred to as, Development and Supportive Elements for QPE in School (DSFQPE) (α = .935), Core Value of QPEtabl (CVPE) (α = .890), and Curriculum Arrangement of Physical Activities (CAPA) (α = .850). The retained items indicated excellent properties and the basic framework as perceived by professionals from PE in LA countries as important in the investigation of QPE.

Resumo Um plano instável para o desenvolvimento de currículos e questões de apoio na educação física (PE) criou confusão entre os profissionais. O objetivo desta pesquisa é investigar os fatores percebidos como importantes no desenvolvimento da educação física de qualidade (QPE) por profissionais de países da América Latina (AL). Um questionário composto por 24 itens com base no QPE foi respondido por 468 profissionais coletados em 6 cidades da América Latina. Uma análise fatorial exploratória dos 24 itens usando extração ML e rotação obliminar direta foram aplicados, e os 17 itens retidos foram agrupados em uma solução de três fatores denominada Elementos de Desenvolvimento e Suporte para QPE na Escola (DSFQPE) (α = 0,935), Valor essencial do QPE (CVPE) (α = 0,890) e Arranjo Curricular das Atividades Físicas (CAPA) (α = 0,850). Os itens retidos indicaram propriedades excelentes e o referencial básico percebido pelos profissionais de EF em países da América Latina como importante na investigação do PEQ.

Resumen Un plan inestable para el desarrollo curricular y aspectos de apoyo para la educación física (EF) han creado confusión entre los profesionales. El propósito de esta investigación es investigar los factores percibidos como importantes en el desarrollo de la educación física de calidad (EFC) por profesionales en países de América Latina (AL). Un cuestionario que consta de 24 ítems basados en EFC fue respondido por 468 profesionales recolectados en 6 ciudades de LA. Se aplicó un Análisis factorial exploratorio de los 24 ítems que utilizan extracción ML y rotación oblicua directa, y los 17 ítems retenidos se agruparon en una solución de tres factores denominada Elementos de desarrollo y de apoyo para EFC en la escuela (EDAEFC) (α = 0,935); Valor principal de EFC (CVPE) (α = 0,890) y Arreglo del plan de actividades físicas (CAPA) (α = 0,850). Los ítems retenidos indicaron excelentes propiedades y el marco básico es percibido por los profesionales de EF en los países de AL como importante en la investigación de EFC.
