Agent-based interoperability for e-government

The provision of valuable e-government services depends upon the capacity to integrate the disperse provision of services by the public administration and thus upon the availability of interoperability platforms. These platforms are commonly built according to the principles of service oriented architectures, which raise the question of how to dynamically orchestrate services while preserving information securi...

Mastoidite aguda em idade pediátrica – Fatores de risco para complicações

RESUMO Introdução: A mastoidite aguda (MA) é a complicação mais frequente da otite média aguda (OMA). A antibioticoterapia (AB) e a melhoria dos cuidados de saúde diminuíram drasticamente a sua incidência. Porém, na última década assistiu-se ao recrudescimento da doença. Objetivos: Avaliar características sociodemográficas, clínicas, laboratoriais e terapêuticas da MA e identificar fatores de risco para complic...

Mastoidite aguda em idade pediátrica – Fatores de risco para complicações

Metastatic Testicular Germ Cell Tumor or a Chemoresponsive Liver Hemangioma?

Testicular germ cell tumors are the most common solid organ malignancy in young adult men. The presence of non-pulmonary visceral metastasis is an independent factor that places such patients into the higher risk group. Hepatic hemangiomas are the most common tumors of the liver and are entirely benign. Overlap between these entities may occur, particularly when metastases are hypervascular. We describe a case ...

Non-Small Cell Lung Cancer: Screening, Diagnosis, and Staging

Lung cancer is the leading cause of cancer deaths worldwide. Tobacco consumption is the primary cause of lung cancer, accounting for more than 85% 90% of all lung cancer deaths. Non-small cell lung cancer accounts for about 85% of all lung cancers. Several studies have shown that low-dose helical CT of the lung detects more nodules and lung cancers, including early-stage cancers, than does chest radiography. Th...

Vasculite Sistémica com Envolvimento das Coronárias numa Adolescente. Qual o Di...

As vasculites sistémicas são raras na idade pediátrica. Apresenta-se o caso de uma adolescente de 14 anos com febre, mialgias, púrpura e edema dos membros, que apresentava leucocitose, velocidade de sedimentação e PCR elevadas. O ecocardiograma mostrou insuficiência mitral, dilatação e aneurisma da artéria coronária esquerda e posteriormente insuficiência cardíaca com hipertensão e pancardite. Detectaram-se tam...
