Patient risk factors for the development of NMSC should be reviewed during the transplant consultation. Individuals found to be at increased risk should undergo closer follow-up and preventive care counseling. This article proposes an algorithm for the prevention of NMSC.
ResumenEl trabajo se realizó en la Reserva Nacional de Lachay, Lima -Perú, el mes de febrero de 1998, durante el Fenómeno El Niño. Se determinó el tamaño mínimo de unidad muestral (TUM) para la evaluación de la diversidad en pit-fall, quedando estandarizado éste en dos trampas pit-fall, con un esfuerzo de siete días por cada trampa. Se obtuvieron, también, valores altos y significativos de correlación utilizando el índice de Pearson, entre la diversidad de sólo el orden Coleoptera y la diversidad de cuatro ordenes de insectos juntos (Hemiptera, Coleoptera, Hymenoptera y Homoptera). Los resultados sugieren que la diversidad de los Coleópteros puede ser considerada como representativa de la diversidad de la comunidad de insectos del suelo. Palabras Claves: Diversidad, muestreo, insectos, Coleoptera, Lachay.
AbstractThe investigation was conducted at Lachay National Reserve, Lima -Peru, in the month of February 1998, during an El Niño Phenomenon. In order to evaluate soil entomological fauna the smallest sample size (SSS) was estimated. It was established at 2 pit-fall traps in an effort of seven days per trap. With the Pearson index high and significant correlation values were found between the order Coleoptera and the other four orders of insects (Hemiptera, Coleoptera, Hymenoptera and Homoptera). Thus, our results suggest that Coleoptera diversity can be established as representative of the diversity of the soil insect community.
for radial distances 0.5 cm # r!5 cm using the line model and 0.5 cm # r! 4 cm for the point model. Multiple source point dose calculations for Symphony vs. VariSeed fell within 1% for distances 0.5 cm # r ! 5 cm. The DVH comparison revealed a maximum difference of 3.9% and 4.6% within the region of high dose gradient (80 Gy to 125 Gy) for the line and point model, respectively, and a mean difference of 0.8% and 1.1% outside the region of high dose gradient, respectively. Volume comparison using the CIRS phantom for MIM vs. Focal fell within 0.4%. Geometrical accuracy of MIM's plan report, digital ruler, and functionality of miscellaneous tool features were verified. Conclusions: This study shows agreement of dose calculations between MIM, VariSeed, and TG-43 formalism for intermediate distances from the source. As mentioned in TG-43, it is expected that the dose calculation becomes more inaccurate in areas of high dose gradient, namely, close to the source and near the end of the source. However, for clinical distances (i.e. r 5 0.5 cm) the dosimetric difference was found to be insignificant (max 0.5%). This was true for both the point dose calculation comparison and DVH comparison. Additionally, deviation in reported volume between MIM and Focal were determined to be acceptable. In conclusion, MIM Symphony was verified as a satisfactory LDR TPS for Cs-131 head and neck implants.
