RESUMO
RESUMEN: La fisura labiopalatina ha tenido una alta frecuencia en la población chilena. A partir del 2000 se inició el programa de fortificación de la harina con ácido fólico a fin de disminuir los defectos del tubo neural. El objetivo de este estudio fue determinar el impacto que presenta la incorporación del ácido fólico en la incidencia de fisuras labiopalatinas de la población del área occidente de la Región Metropolitana. Se recopiló información a partir de las fichas clínicas de la Fundación Gantz seleccionando a los recién nacidos entre 1990 y 2009, correspondientes a las comunas del Servicio de Salud Occidente de la Región Metropolitana. Desde el 2000 hasta el 2004 se observó una disminución importante en las tasas de fisura labiopalatina, con una tasa de 0,88 fisurados por 1000 recién nacidos vivos. Posteriormente se observó un incremento a partir del 2005 hasta el 2009 llegando a una tasa de 1,52 fisurados por 1000 recién nacidos vivos. En conclusión, el efecto protector del ácido fólico se evidencia en la disminución de las tasas de los recién nacidos con fisuras durante los primeros años de su implementación. Sin embargo, posteriormente se observó un aumento de dichas tasas, lo cual podría deberse al incumplimiento de la norma.
ABSTRACT: Cleft lip and palate has had a high frequency in the Chilean population. From the year 2000 a flour fortification program with folic acid was initiated in order to reduce the defects of the neural tube. The objective of this study was to determine the impact of the incorporation of folic acid in the incidence of cleft lip and palate of the population of the western area of the Metropolitan Region. Information was collected from clinical records of the Gantz Foundation, selecting newborns from 1990 to 2009, corresponding to the districts of the western sector of the Metropolitan Region. From 2000 to 2004 there was a significant decrease in cleft lip and palate rates, with a rate of 0.88 cases per 1000 live births. Subsequently, an increase was observed from 2005 to 2009, reaching a rate of 1.52 cases per 1000 live births. In conclusion, the protective effect of folic acid is evidenced in the reduction of the rates of newborns with cleft palate during the first years of its implementation. However, an increase in these rates was subsequently observed, which could be due to noncompliance with the standard.

PURPOSE: We have clinically observed that larger rotational setup errors are more prominent in pediatric patients who received radiation therapy for brain tumors. In this work, we quantitatively evaluated the daily setup corrections in pitch, roll, and yaw axes for children who received intracranial radiation therapy under x-ray image guidance. METHODS: Daily localization data of 43 patients between the ages of 10 months and 21.9 years were analyzed in this study. Patients were immobilized with thermoplastic mask during treatments, and 2D orthogonal x-ray images wereacquired for setup corrections before each treatment. Rotational setup corrections in pitch, roll, and yaw axes were extracted from 873 treatment fractions, and were analyzed for the whole group of patients and for two age groups: < 5 and = 5 years old. RESULTS: The mean values for the pitch corrections were 1.91° and 1.65° (p:0.02), roll corrections were 1.37° and 1° (p<0.001), and yaw corrections were 1.93° and 1.47° (p<0.001), respectively. For patients < 5 years, 21.7% of treatments had pitch corrections more than 3°, versus 15.6% of treatments required pitch corrections more than 3° for patients >= 5 years. Similarly, 10.6% of roll corrections and 20.9% of yaw corrections were more than 3° for patients < 5 years. On the other hand, 2.1% of roll and 13.8% of yaw corrections were more than 3° for patients = 5 years old. CONCLUSIONS: Data indicate that children less than 5 years old are more prone to rotational setup errors during intracranial radiation therapy. This can be attributed to reduced efficacy of immobilization devices due to smaller and rounder anatomicalfeatures of pediatric patients, and challenges in setup while the patient is under anesthesia. The role of daily image guidance and rotational setup corrections becomes important to ensure target coverage, especially for children < 5 years old.
RESUMO
El cuidado de sus niños pequeños es una necesidad de la comunidad que ha venido siendo atendida de diverso modo. En 1993 se formaliza la atención de los infantes a través de Hogares Educativos Comunitarios o Proyecto Wawa-Wasi. Paralelamente, el Programa de Salud Mental Comunitario del Instituto Nacional de Salud Mental "Honorio Delgado-Hideyo Noguchi" crea un subprograma específico de salud mental del pre-escolar, a través del cual se realiza un diagnóstico situacional de 34 de tales servicios ubicados en el distrito de Independencia. Los resultados evidencian algunas deficiencias en el ambiente físico así como en la capacitación y desempeño de roles de la madre educadora, para las cuales se sugieren recomendaciones.
The care of children is a social need that has attended in different ways. Since 1993 the care was made official through the Wawa-Wasi project or Educational Community Houses. Complementary, the Community Mental Health Program of the Instituto Nacional de Salud Mental Honorio Delgado-Hideyo Noguchi (Lima, Peru) develops an specific pre-school children subprogram and on this ground a situational diagnosis of 34 of these services located in Independencia district was made. Results show some deficiencies of the physical environment as well as of the level of training and role performance of the educator mother for which recommendations are suggested.
