Abstract: Las dolencias producidas por la caries dental y otras afecciones bucales son múltiples, lo que hace al paciente acudir a los servicios de urgencia. El propósito de este trabajo fue evaluar la relación del estreptococo mutans y lactobacilo y algunas variables demográficas con la caries dental en ni os, pertenecientes a cinco consultorios del área de Contreras, del municipio de Matanzas, para lo cual se realizó un estudio analítico del tipo de casos y controles. La muestra se obtuvo mediante un dise o muestral probabilístico estratificado polietápico y quedó conformada por 900 ni os (300 casos y 600 controles) de 6 a 12 a os de edad. Hubo un predominio de ni os en las edades de 6 a 8 a os, tanto en los casos como en el grupo control, y no se observaron diferencias significativas entre ambos grupos. El sexo femenino prevaleció en los controles, y el masculino, en los casos. Los ni os pertenecientes al grupo de casos, tenían un alto grado de infección por estreptococo mutans y lactobacilos, y se demostró asociación positiva de la caries dental con estas variables. Se dise ó una estrategia educativa para evaluar y elevar el nivel de información que sobre esta enfermedad tenían los ni os objetosde estudio.

Abstract: La respiración normal involucra la utilización adecuada del tracto nasal y nasofaríngeo. Un aumento de volumen de las estructuras que se encuentran dentro de esos espacios, imposibilita el paso de aire por estos conductos, y el resultado será que el ni o respire por la boca, trayendo serias alteraciones en el aparato estomatognático que afectan al ni o de forma estética, funcional y psíquicamente. Se realizó un estudio descriptivo transversal, con el objetivo de caracterizar clínica y epidemiológicamente la respiración bucal en ni os de 3 a 5 a os en la parroquia Catia La Mar, de enero a junio de 2008. El universo estuvo constituido por 350 ni os, y la muestra la conformaron 100 ni os que practicaban el hábito de respirador bucal. El hábito de respirador bucal se observó en los ni os de menor edad con mayor frecuencia en el sexo masculino. La respiración bucal patológica predominó sobre la respiración bucal por hábito en los varones. El asma bronquial y la bronquitis asmática predominaron en las edades de 3 y 5 a os; el más afectado fue el sexo masculino, mientras que en las hembras predominó la rinitis alérgica en la edad de 5 a os. Los pacientes con obstrucción de las vías respiratorias fueron respiradores bucales, y predominó la hipertrofia adenoidea y/o amigdalar y la hipertrofia de cornetes para las hembras y la desviación del tabique para los varones.

Abstract: Las publicaciones en el campo de la medicina representan en cualquier intervalo de tiempo una evidencia verificable de los aportes realizados al desarrollo de la ciencia. El desarrollo alcanzado por la medicina y la salud pública originó un incremento considerable en la aparición de revistas especializadas y su publicación periódica con adecuada calidad. El estudio caracteriza la producción científica de los profesionales de la salud e instituciones en las dos etapas que distinguen a la Revista de Ciencias Médicas de Pinar del Río impresa y digital. Los métodos fundamentales de investigación lo constituyeron el histórico-lógico, la revisión bibliográfica, el método de análisis-síntesis, la inducción-deducción y el método de revisión de documentos. Se ha publicado un total de 580 artículos originales, 7 artículos de revisión, 72 presentaciones de casos y 44 editoriales, para un total de 704 publicaciones, lo que significa un índice de producción científica promedio histórico muy bajo si se considera como indicador. Aún cuando en el sector de salud de la provincia Pinar del Río existen las condiciones creadas para la socialización de los resultados que se obtienen en el campo de la investigación científica médica y de formación de sus profesionales, el índice de producción científica es insuficiente. Estimular su elevación se ha convertido hoy en una prioridad para los distintos niveles de dirección, creándose un ambiente favorable para alcanzar niveles superiores con artículos de calidad que prestigian a nuestra revista, a nivel nacional e internacional.
