A Comparison of the Academic Achievement at the End of the Medicine Undergraduate Degree Program Between Students Who Only Used the University Admission Test and Those Who Used the University Admission Test Plus Marks from the High School National Exam (ENEM) at a Single Brazilian Center.

Purpose: The role of marks in the University Admission Test (UAT) plus the marks from pre-university academic records in predicting academic achievement at the end of the Medicine undergraduate degree program is not completely known. This study was undertaken to compare the performance of marks in the UAT alone with those of the UAT plus marks from the National High School Exam (ENEM in Brazil) regarding students' outcomes at the end of the Medicine undergraduate degree program. Methods: Fifty-one (51) students from the last semester (12th) of our Medicine undergraduate degree program were included in the study. They were divided into a group of those who used the marks obtained in the UAT plus the marks obtained in the ENEM (ENEM group, n=9), and those who only used the marks in the UAT (non-ENEM group, n=42). We compared the academic achievement of the non-ENEM group with that of the ENEM group regarding the mean marks obtained in the clerkship, in the Progress Test (PT), and in the Objective Structured Clinical Examination (OSCE). Results: The mean scores obtained in the disciplines of the clerkship were higher in the non-ENEM group compared to the ENEM group (7.32 ± 0.41 vs 6.98 ± 0.31, p= 0.01). Both groups obtained similar mean marks in the OSCE and in the PT. A moderate correlation was observed between the marks in the clerkship with those of the UAT from the non-ENEM group (p=0.00006; r=0.45). Conclusion: Marks of the UAT alone appear to be associated with a higher academic achievement in the clerkship than marks of the UAT plus scores obtained from the ENEM at the end of the Medicine undergraduate degree program.

Avaliaçäo do DNA pela citofotometria nos tumores papiliferos da tireoide / DNA evaluation by cytophotometry in papillary thyroid tumour

A avaliacao quantitativa do DNA tem sido realizada em varios tumores malignos, inclusive da tireoide. Tem sido encontrado aumento da percentagem de aneuploidia em tumores de mau prognostico, enquanto que os carcinomas com distribuicao do DNA euploide seguem um curso benigno. Neste trabalho estudamos o teor do DNA nuclear de vinte casos de carcinomas papiliferos propriamente dito e dezenove de variantes papilifero. O metodo utilizado foi da citofotometria de lamina. Os histogramas foram classificados de acordo com Auer. A aneuploidia (tipo IV) esteve presente em 35,90% de todos os casos estudados.Entre os dois grupos de carcinoma papilifero nao foi observada diferenca significativa na distribuicao dos valores de DNA. Embora a literatura mostre que as variantes papiliferas tem um prognostico pior, nao pudemos comprovar analisando o conteudo de DNA nuclear. Concluimos que a citofotometria para avaliacao do DNA pode fornecer dados que permitem melhor estabelecer o prognostico de um determinado paciente, isoladamente
