Es una lesión reactiva, no tumoral, que afecta a la mucosa oral, las semimucosas y la piel de extremidades. Su presentación clínica consiste en una lesión única, elevada, de superficie irregular. Su característica microscópica es la acumulación de macrófagos con lípidos en las papilas del tejido conectivo entre las crestas epiteliales. En el presente reporte se revisa la literatura y un caso de esta patología. Se trata de una paciente de sexo femenino de 11 años de edad, que acude a consulta con su tutor. Clínicamente, se observa una lesión única de color rosa pálido, de 4 mm de longitud aproximadamente, de forma ovalada con bordes definidos, superficie rugosa, queratinizada, de consistencia firme y base adherida al tejido. Se realiza biopsia excisional y estudio histopatológico. Se concluye que diagnosticar el xantoma verruciforme es complejo; aunque es una lesión benigna, se puede confundir con otros diagnósticos diferenciales malignos, por lo cual recomendamos evaluar la anamnesis, los factores de riesgo y establecer un plan de tratamiento acertado.

Method: A non-experimental, descriptive and transversal study was conducted. The Honey-Alonso learning style questionnaire was given to 535 students. The average scores observed in each course underwent regression curve type studies. The standard deviation of each average over the fitted regression curve was estimated with its corresponding confidence interval and determination coefficient. Results: The results showed that the active, reflective and pragmatic style presented a fluctuating development as the academic years progressed; with the exception of the theoretical style, which demonstrated a steady increase. All learning style scores increased in the fifth year. Conclusion: It can be concluded that upon reaching the higher levels, there is a development of all learning styles, which signifies tha...

Method: This is an exploratory, non-experimental, descriptive and cross sectional study with a sample of 601 students (65 % of students). Two questionnaires were applied during the second semester of 2015. The first: A structured questionnaire designed to collect data on alcohol consumption and its characteristics. The second: the Alcohol Use Disorders Identification Test. The data was analyzed using descriptive statistics. The association of the dependent variable “alcohol” with the independent variables “age”, “ gender”, “geographic location of origin” and “semester” were evaluated by a binomial logistic regression. Then, the data observed in subjects who reported drinking alcohol were evaluated. The significance level used in all cases was α≤0.05. Results: 15 % is a risk consumer, and 18% is a harmful consumer or have a p...

La asociación de la variable dependiente "alcohol" con las variables independientes "edad", "género", "ubicación geográfica de origen" y "semestre académico" fueron evaluados mediante una prueba de regresión logística binomial. Sólo los datos de los sujetos que consumían alcohol fueron evaluados. El nivel de significación empleado en todos los casos fue de α≤0,05. Resultados: El 15% de los estudiantes es consumidor de riesgo y 18% presenta consumo perjudicial o posible dependencia. En estudiantes que consumen alcohol, la variable ingreso familiar, en relación con las variables época del año en que consumen y la presencia de problemas derivados del alcohol, están asociadas. Conclusión: Existe mayor prevalencia de consumo en el género masculino y un alto consumo de bebidas alcohólicas en ambos géneros en cualquier época del año. El consumo de bebidas alcohólicas es independiente del ingreso familiar.

The average scores observed in each course underwent regression curve type studies and the standard deviation of each average over the fitted regression curve was estimated with its corresponding confidence interval and determination coefficient. Results: The active, reflective and pragmatic style presented a fluctuating development as the academic years progressed; with the exception of the theoretical style, which demonstrated a steady increase. All learning style scores increased in the fifth year. Conclusion: Upon reaching the higher levels, there is a development of all learning styles, which means that students adapt to learning through different strategies and have the capacity to adapt to different situations, which facilitate learning. However, we suggest that dentistry, as a clinical career, should promote the active and reflective styles, because they would be the most beneficial in helping students to develop the skills required to successfully face clinical experiences in their practice period, or within the clinical workforce.

METHODS A Cross-sectional design study with a sample of 265 dentistry students was carried out. RESULTS Using structural equation modeling, confirmatory factor analysis verified the adequacy of four-factor model, although the only factor that directly predicts behavioral intention is performance expectancy. Internal consistency coefficients of each factor ranged from 0.800 to 0.969. DISCUSSION These findings, as well as the predictive power of performance expectancy on behavior intention, are in line with previous evidence found in the literature. CONCLUSION These findings suggest that the UTAUT scale has adequate relia...
