Abstract: Objetivo: establecer la frecuencia de estreptococo beta hemolítico del grupo A (Streptococcus pyogenes) en ni os, mediante una prueba rápida de inmunoensayo cromatográfico.Métodos: estudio piloto de tipo transversal en una muestra no probabilística de 144 ni os entre 3 y 13 a os, asistentes a centros infantiles de Medellín y su área metropolitana y a una institución educativa de Bogotá. Se tomaron muestras de garganta por frotis para la prueba rápida de S. pyogenes y se recolectó información demográfica y de antecedentes personales mediante una encuesta. Se calcularon los promedios con sus desviaciones estándar y los porcentajes de acuerdo con la naturaleza de las variables de interés.Resultados: la edad promedio del grupo fue 5,5 ± 2,8 a os con distribución similar por sexo. Veintiún ni os (14,6%) fueron positivos para S. pyogenes, diez de ellos fueron posibles infecciones y 11, portadores asintomáticos. De los 144 ni os, 45 (31,3%) tenían síntomas faríngeos, de los cuales 10 (22,2%) tenían S. pyogenes. Un total de 99 (68,8%) ni os fueron asintomáticos y 11 de estos (11,1%) presentaron prueba positiva para S. pyogenes.Discusión: la alta frecuencia de S. pyogenes en este grupo es un llamado de atención sobre la necesidad de implementar protocolos de manejo con pruebas rápidas para la detección del microorganismo.

Abstract: Objetivo. El propósito del estudio fue evaluar el desempe o del método VERSANTHIV-1RNA 1.0 Assay (kPCR) (Siemens), para la cuantificación de la carga viral en pacientes con VIH-1, en comparación con el método COBAS AmpliPrep/COBAS TaqMan HIV-1 test , v2.0 (Roche Diagnostics) (CAP/CTM). Métodos. Las muestras fueron tomadas en dos tubos con EDTA, de 60 pacientes remitidos por el médico tratante para pruebas de carga viral como parte de su control de rutina de VIH/sida, y fueron procesadas para la cuantificación del ARN del VIH-1 por ambas técnicas. Se hizo análisis de regresión y se calcularon los coeficientes de correlación de Pearson, y los de correlación y concordancia de Lin. Se evalúo la concordancia entre las dos técnicas mediante el método de Bland-Altman. Resultados. El promedio de la carga viral por el método CAP/CTM fue 3,2±1,4 long10 copias/ml y, por el método kPCR, 3,0±1,3 long10 copias/ml. El 86,7 % de muestras presentó diferencias entre los dos métodos, menores de 0,5 long10 copias/ml, y el 13,3 % presentó diferencias mayores. El coeficiente de correlación de Pearson entre los dos métodos fue de 0,97 (IC95% 0,95-0,99) y el índice kappa ponderado entre los dos métodos en diferentes rangos de concentración, fue de 0,91 (IC95% 0,87-0,96). El promedio de las diferencias entre las mediciones fue 0,22 long10 copias/ml (IC95% -0,45 a 0,89). Conclusión. Las dos técnicas evaluadas fueron comparables, con el método kPCR se observaron resultados más bajos.

Abstract: INTRODUCCIóN: el propósito de este estudio fue estimar la prevalencia de fluorosis dental en escolares entre los 6 y 13 a os de edad, asistentes en 2007 a instituciones educativas privadas de la ciudad de Medellín, Colombia. MéTODOS: se examinaron 752 ni os de 20 colegios, seleccionados al azar. Dos odontólogas entrenadas y calibradas en el diagnóstico de fluorosis dental, realizaron la evaluación clínica de los escolares previo cepillado dental. Se examinaron las superficies vestibulares de los dientes superiores, mediante inspección visual y con luz natural. Se utilizó el índice de Thylstrup y Fejerskov (TFI) para el diagnóstico y registro de la fluorosis dental. RESULTADOS: la prevalencia de fluorosis dental en los escolares fue 79,1% (TFI ≥ 1); de los cuales el 50,8% tenía únicamente grados leves (TFI1 ó 2 ), mientras que el 5,1% presentó grados severos, TFI ≥ 5. Se encontró que el 17% de los ni os, tenía TFI ≥ 1 en el 50% o menos de los dientes. CONCLUSIONES: en los escolares de los colegios privados de Medellín la prevalencia de fluorosis dental fue alta. Se requiere la formulación de estrategias de intervención por parte de las autoridades de salud, que contribuyan al control de los procesos de riesgo para la fluorosis.

Abstract: INTRODUCCIóN: el objetivo fue establecer la prevalencia de caries dental no tratada y las necesidades de tratamiento en ni os de uno a cinco a os del barrio Moravia de Medellín. MéTODOS: se realizó un estudio descriptivo transversal, en 162 ni os. Un examinador calibrado (Kappa 0.73) evaluó el estado de la dentición de los ni os -según criterios de Pitts y Fyffe, que establecen niveles de avance de las lesiones de caries dental (D1-D4)- y con base en este se determinaron las necesidades de tratamiento, teniendo en cuenta lineamientos actuales de un enfoque más preventivo. Los datos se analizaron en el programa SPSS 15.0; se estimó la proporción de ni os con caries dental no tratada y el promedio de dientes para los diferentes tipos de tratamiento y sus desviaciones estándar. RESULTADOS: the gray tone scale varied from 0 to 255, corresponding to the value of the tones of pixels observable and dependent on electric current in Digital radiographic technology applied to maxillofacial area. CONCLUSIONES:la alta prevalencia de ni os con caries de la infancia temprana (ECC) y lesiones de caries dental no tratada reflejan el problema de necesidades de atención acumuladas en esta población, lo cual hace evidente la relación de la caries dental con la inequidad y condiciones de vida que limitan el acceso a la atención odontológica oportuna y efectiva.
