RESUMO
Context: Radiographs have an essential role in Chronological Age (CA) estimation and are being used for dental age (DA) determination. Aims: Detecting the validity of Nolla’s method (NM) for the age assessment of Kurdish Iraqi children (KIC). Methods and Material: A retrospective study was performed using orthopantomographs (OPGs) of 354 subjects aged from 4 to 13 years (178 boys and 176 girls) and their recording files. Subjects were divided into nine study groups: 4, 5, 6, 7, 8, 9, 10, 11, 12, and 13 years old. The chronological age (CA) was subtracted from the DA to find the validity of NM; the positive results indicated the overestimation of age, whereas the negative results indicated for underestimation. The data were recorded through a digitalised system using Microsoft Excel worksheet and analysed by Statistical Package for the Social Sciences (SPSS, version 25) programme using the dependent T?test and graphical analysis. The level of P value used in this study was set at < 0.05. Results: The DA is underestimated in ages 9 to 13 in boys and girls. The highest difference in DA–CA was at the age of 9 years (?0.146 ± 0.162). Conclusions: NM for age estimation was slightly overestimated in age groups of 4, 5, 6, 7, and 8 years in boys and girls without statistically significant differences. However, this method underestimated the ages of KIC ranging from 9 to 13 years significantly.
RESUMO
Objective The purpose of this study is to estimate the living age by MRI T2-FS images of the knee and to establish a new age estimation method without radiation in Sichuan Hans population. Methods We retrospectively evaluated sagittal T2-weighted, fat-suppression and turbo spin-echo sequence taken upon MRI of 324patients (170 males, 154 females; age 10~30) using a six-stage method. The gender difference was tested by Mann-Whitney U and the correlation between the knee and age height was tested by Spearman correlation coefficient. Regression models were built for age estimation in both genders. Results The correlation between the distal femur and age was 0.687 in males and 0.661in females and was 0.684 in males and 0.488 in females between the proximal tibia and age. Comparison of male and female revealed nonsignificant differences in the ages at the stages 1~3, 5, 6 of the distal femoral epiphysis and stage 1~3, 5 of the proximal tibial epiphysis. The fusion of distal femur commenced at 18.42 years in males and 19.36 years in females. The fusion of proximal tibia commenced at 16.93 years in males and14.68 years in females. The test of accuracy showed MAD=2.90 years in the males and MAD=3.30 years in the females in the compound regression model. Conclusion MRI T2-FS images of the knee can be an indicator for age estimation in the living and stage 6 of the distal femur can be used to determine 18-year limit.
RESUMO
El material que se presenta es parte de una investigación en curso, respecto de las intervenciones de médiums durante sesiones de videncia con consultantes que padecen un estado de duelo prolongado por la muerte de una persona querida. En este caso se trata de un duelo familiar, de difícil tramitación. Los consultantes, una pareja, han perdido a su hijo adolescente en un accidente automovilístico. Se comentan los resultados del análisis de una sesión de clarividencia protagonizada por el médium Gordon Smith con Colin y Pat, padres del joven fallecido -el video documental fue presentado en Mediums, the New Therapists, programa emitido por la señal del canal Infinito-.Se analizan las intervenciones del médium a partir de los deseos en los actos del habla -escenas desplegadas- y sus probables funciones, las que permiten realizar hipótesis acerca del modo en que ejerce con eficacia la función sanadora. También se analizan los deseos del médium en el nivel de las palabras, cuestión que nos orienta en cuanto a su disposición subjetiva. Finalmente, se analizan los componentes paraverbales y los desempeños motrices en los episodios de mediumnidad. Se discuten los resultados obtenidos. El método de investigación es el Algoritmo David Liberman ADL-.
