Impulsionadas pela globalização, empresas transnacionais, instaladas no Brasil, estão colaborando para a formação de um novo perfil profissional para executivos brasileiros. As mudanças que derivam deste cenário passam a exigir dos profissionais conhecimentos e aptidões diferenciadas para a atuação no ambiente atual de negócios. O presente estudo busca traçar o perfil ideal do executivo em face das exigências do mercado globalizado, destacando-se os principais atributos que este profissional deve apresentar, segundo a visão de profissionais decisores das 500 maiores empresas do ranking da revista Exame (1997). Realizou-se uma pesquisa descritiva, a partir de duas etapas: uma exploratória, na qual se geraram os atributos a serem avaliados e uma quantitativa, para a mensuração do grau de importância de cada indicador arrolado. Os atributos referentes ao perfil do executivo no mercado considerados mais importantes são: integridade, visão estratégica, liderança, conhecimento das operações da empresa, capacidade de decisão, negociação e coordenação de trabalhos em equipe, foco nos resultados, ética no trato das questões profissionais e sociais, motivação, pró-atividade e habilidade para o trato interpessoal.
Objective: To evaluate the role of PET/CT in the approach to patients with head and neck cancer. Materials and Methods: Retrospective study of medical records and PET/CT images of 63 patients with head and neck cancer. Results: Alterations were observed in 76% of the cases. Out of these cases, 7 (11%) were considered as false-positive, with SUV < 5.0. PET/CT demonstrated negative results in 15 cases (24%). Among the 14 cases where the method was utilized for staging, 3 (22%) had their stages changed. Conclusion: PET/CT has shown to be of potential value in the routine evaluation of patients with head and neck cancer, but further studies of a higher number of cases are required to define a protocol for utilization of the method.

Materiais e Métodos: Estudo retrospectivo de 63 prontuários e exames de PET/CT de pacientes com câncer de cabeça e pescoço. Resultados: Foram encontradas alterações em 76% dos exames. Destes, 7 (11%) foram considerados falso-positivos, com SUV < 5,0. A PET/CT mostrou-se negativa em 15 situações (24%). Dos 14 casos nos quais se utilizou o exame para estadiamento, em 3 (22%) houve aumento no estadiamento. Conclusão: A PET/CT mostra-se como exame de potencial valor na rotina de avaliação de pacientes com câncer de cabeça e pescoço, entretanto, necessitamos de maior número de casos para definirmos protocolo de uso.

Introduction Here we report estimates of glomerular basement membrane (GBM) thickness in the Brazilian population performed using direct (DM) and orthogonal interception methods (OIM), and comment on potential sources of variation among estimates made by different laboratories. Methodology A total of 38 patients, ranging from 3 to 78 years of age, 26 (68%) males and 12 (32%) females, were submitted to kidney biopsy procedures for renal disease diagnosis. Glomeruli were diagnosed with minor histological changes by conventional, immunofluorescence and electron microscopy. GBM thickness was estimated using both DM and OIM methods. Results Estimates of GBM thickness obtained using DM were higher than those obtained by OIM. However, the application of a correction for non-perpendicular membrane sectioning to DM estimates yielded similar results to those obtained under OIM. The estimated GMB thickness using DM after correction was 289 + 44 nm, versus 287 + 48 nm by OIM. No statistically significant differences were detected in GMB thickness, nor with respect to patient age or sex. Conclusions GBM thickness in the studied Brazilian population measured approximately 290 nm. The application of criteria for estimating the shortest distance between the endothelial and podocyte cell membranes with correction for non-perpendicular membrane sectioning can increase the accuracy of GBM thickness estimates using DM and OIM.
