Characteristics and outcomes of the Spanish registry for pediatric patients with bicuspid aortic valve (REVAB).

INTRODUCTION AND OBJECTIVES: Bicuspid aortic valve (BAV) disorder is the most common congenital heart disease. The aim of this study was to describe the characteristics of 0- to 18-year olds with BAV in a population-based registry. METHODS: Data from all pediatric patients were obtained from the Spanish registry for pediatric patients with bicuspid aortic valve (REVAB) (< 18 years). For data analysis, patients with BAV were divided into 2 groups by their features: isolated BAV and BAV with associated congenital heart disease. RESULTS: We included 1681 patients from 33 hospitals. Males accounted for 69.6% (n = 1158). Valve morphology was horizontal in 63.4% (n = 1012) and pure (Sievers type 0) in 28.4% (n=469). Isolated BAV was present in 63.7% (n=1060), and concomitant left-sided obstructive lesions in 23.4% (n=390). Interventions were required in 8.6% (n=145). CONCLUSION: These data represent the first large, population-based description of the clinical presentations and outcomes of patients enrolled in the Spanish registry for pediatric patients with bicuspid aortic valve.

Salud oral: influencia de los estilos de vida en adolescentes / Adolescent lifestyle and its influence on oral health

INTRODUCCIÓN: la alta prevalencia de patología bucodental en adolescentes, junto con la relación directa o indirecta entre patología y hábitos, hacen necesaria la prevención y promoción oral a nivel escolar, sanitario y familiar. Nuestro objetivo principal fue mediante un cuestionario sobre hábitos de estilo de vida en adolescentes, conocer la prevalencia de estos y su relación con la salud bucodental. MATERIAL Y MÉTODOS: estudio observacional de corte transversal en 39 escolares, preadolescentes y adolescentes de 12 a 17 años. Se realizó un cuestionario de 42 preguntas que fue entregado a los participantes. Los resultados obtenidos se analizaron mediante tablas de contingencia y con un valor de significación p <0,05. RESULTADOS: la prevalencia de escolares con correcta frecuencia de cepillado es del 54% y solo el 48,7% visita al odontólogo una vez al año. Existe relación significativa entre la nacionalidad y las visitas al dentista (p = 0,02) o entre la frecuencia de cepillado con el desayuno (p = 0,005), consumo de bollería industrial o bocadillos (p = 0,02), o refrescos (p = 0,011), utilización de ordenador, televisión y videoconsola (p = 0,049); y el sedentarismo (p = 0,00). CONCLUSIÓN: se obtuvieron resultados estadísticamente significativos al relacionar hábitos de estilo de vida y salud oral. En la adolescencia es fundamental la creación de estrategias de prevención y promoción en salud dental, para instaurar rutinas correctas que no afecten a la salud general del adolescente

INTRODUCTION: the high prevalence of oral disease in adolescents, together with the direct or indirect association between disease and lifestyle habits, call for the implementation of oral health prevention and promotion strategies at the school, household and public health levels. Our main objective was to design a questionnaire on lifestyle habits in adolescents to determine their prevalence and assess their association with oral health. MATERIALS AND METHODS: we conducted a cross-sectional observational study in 39 preadolescent and adolescent students aged 12 to 17 years. We developed a 42-item questionnaire and administered it to participating students. We analysed the obtained responses using contingency tables, defining statistical significance as a p-value of <0.05. RESULTS: we found that the frequency of brushing was correct in 54% of participating students, while only 48.7% visit the dentist every year. We found a significant association between nationality and visits to the dentist (p = 0.02) and between the frequency of brushing with: eating breakfast (p = 0.005), consumption of industrial baked goods or snacks (p = 0.02) and consumption of sugary drinks (p = 0.011), the use of computer, television and gaming consoles (p = 0.049), and a sedentary lifestyle (p = 0.00). CONCLUSION: we found statistically significant associations between lifestyle habits and oral health. The development and implementation of oral health prevention and promotion strategies targeting the adolescent population is essential in order to establish adequate habits that will not have a detrimental effect on the general health of the adolescent

Influence of fluoride varnish on shear bond strength of a universal adhesive on intact and demineralized enamel.

The aim was to evaluate the effect of fluoride varnish on the shear bond strength (SBS) on polished and non-polished intact and demineralized enamel. Bovine incisors (half demineralized) were used. Bifluorid 12™ was applied. Bonding was made with Futurabond®M + and GrandioSO, 24 h and 7 days after varnishing. In some groups, varnish was removed by polishing before bonding. SBS was measured. Fracture type was determined by stereomicroscopy and scanning electron microscope (SEM) observations of the enamel surface were made. Between-group differences were determined by one-way ANOVA and the Tukey test. Associations between study factors and fracture modes were analysed using contingency tables and Pearson's chi-squared test. For intact enamel, SBS on varnished enamel at 24 h was significantly less than in the other groups. SBS recovered 7 days after varnishing. Varnish elimination after 24 h significantly increased the SBS. However, removal at 7 days did not modify SBS. SBS on demineralized enamel groups was significantly less than in intact enamel, except for demineralized enamel varnished and removed at 7 days. Demineralized enamel was associated with cohesive enamel fractures and intact enamel with cohesive fractures of the composite and adhesive fractures. SEM of varnish surfaces showed a homogenous layer scattered with amorphous precipitate. In conclusion, on intact enamel fluoride varnish had a negative effect on SBS at 24 h, which disappeared after 7 days. On demineralized enamel, varnish did not reduce SBS at either time. Polishing the varnished enamel surface showed a similar SBS to intact enamel after 7 days.
