Colonization of the lower respiratory tract by enteric Gram-negative bacilli (EGNB) has been a frequent finding in patients with long-term tracheostomies; however, the association of hospitalization and certain features of serious illness with this phenomenon has not been clearly established. Because such factors can render the oropharynx more susceptible to EGNB colonization, we sought to disc...

Tracheobronchial amyloidosis is an infrequent disease characterized by the deposition of proteinaceous material in the tracheobronchial tree. The disease generally has a high morbidity and variable mortality in the years following diagnosis. There is no consensus on the optimal treatment. We report a case of a 63-year-old woman who presented with a diffuse tracheobronchial amyloidosis associate...

Seven cases of injury to the tracheobronchial tree in closed trauma of the thorax, treated by the surgical emergency service of the Hospital das Clínicas, University of São Paulo School of Medicine, during the period 1980-2 are described and compared with previously published cases. The diagnosis of the seven cases presented in this series was clinically suspected and endoscopically confirmed w...

Background: Endotracheal and endobronchial tuberculosis are defined by microbiological and histopathological evidence of tuberculosis involving tracheobronchial tree, with or without parenchymal involvement. Tracheal tuberculosis is a rare and localized form of tuberculosis which can present itself with acute respiratory failure due to upper airway obstruction. Case presentation: We present a c...
