Archival information and organic information: a conceptual analysis of the Brazilian literature

Information has increasingly become a crucial resource for organizations that want to remain competitive in the market. For this reason, analysis and a correct understanding of informational types that are present in these environments become relevant to achieving the highest levels of performance. The aim of this paper is to review the literature of the concepts of organic and archival information within the organizational context/business environments. This is still an emerging theoretical field and therefore is conducive to intense discussions. We point out elements that help to characterize and distinguish these two types of information.

Peritoneal pseudomyxoma associated with synchronic malignant mucinous neoplasias of the cecum, appendix and rectum: case report and review of the literature

O pseudomixoma peritoneal é uma condição patológica que acomete o peritoneo, caracterizada pela produção de grandes quantidades de líquido mucinoso, que progressivamente preenche a cavidade peritoneal, tendo em geral como origem tumores mucinosos apendiculares ou de ovário. Relatamos a ocorrência de um pseudomixoma peritoneal associado a adenocarcinoma mucinoso do apêndice sincrônico e adenocarcinoma do reto em paciente de 44 anos, cujo diagnóstico inicial foi de adenocarcinoma do reto. A neoplasia do apêndice e o pseudomixoma peritonial foram achados incidentais, intra-operatórios. Enfocamos as principais características anatomo-patológicas das lesões, o diagnóstico e tratamento, através de ampla revisão da literatura.

Persistent Pleuropulmonary Air Leak Treated with Autologous Blood: Results from a University Hospital and Review of Literature

Background: Persistent air leak after pulmonary resection is a difficult complication for thoracic surgeons to manage. Objectives: To show the results of our experience treating persistent pleuropulmonary air leak with autologous blood and review the literature on this specific method of treatment. Methods: Retrospective study of patients with persistent aerial pleuropulmonary fistula treated with autologous blood. The patient's own blood was collected from a peripheral vein and directly introduced through the pleural drain. An inverted siphon was located in the drainage system to avoid prolonged clamping of the drain. This siphon impeded blood return but not air escape. Results: Between January 2001 and August 2008, 27 patients were treated by the above method. Patient age ranged from 2 to 74 years, and 78% were male. Each procedure used a mean quantity of 92 ml blood. Mean persistent air leak time before pleurodesis was 10.6 days and mean time to fistula resolution after pleurodesis was 1.5 days. Twenty-three (85%) patients had persistent pleuropulmonary air leak closed with the above procedure. Conclusion: Treating persistent pleuropulmonary air leak with autologous blood is promising, but further studies are required to quantify its real effectiveness. Copyright (C) 2009 S. Karger AG, Basel
