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...

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...

BACKGROUND Bradykinin, a nonapeptide that contributes as a mediator to the pathogenesis of asthma, may affect lung mucociliary clearance, as it has been shown to be a potent secretagogue in canine airways and in human nasal mucosa in vivo. To evaluate this possibility the effect of inhaled bradykinin on mucociliary clearance has been studied in 10 healthy volunteers. METHODS Subjects attended...

OBJECTIVES To analyze the clinical data of four patients with a diagnosis of tracheobronchial endometriosis, and to reappraise the diagnostic value of bronchoscopy and bronchial brush cytology in these patients. METHODS We conducted a retrospective study of four patients with documented tracheobronchial endometriosis treated at National Taiwan University Hospital from 1994 to 1998. The comple...

BACKGROUND Tracheal and bronchial stenosis is a life-threatening condition causing difficulty in breathing and even severe respiratory distress. The silicone tracheobronchial stents were placed using the rigid bronchoscopy into the trachea of severe dyspneic patients and they exhibited symptomatic improvement as well as a rise in the saturation of oxygen. The bronchial stents were applicable to...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016219127 DESCRIPTION A man aged 56 years with a history of HIV and diffuse B-cell lymphoma (in remission) was referred to our institute for management of pancytopenia and acute kidney injury. Five days prior to the admission, the patient went to a dental clinic for tooth ex...

Amyloidosis is a disease characterized by extracellular deposition of fibrillar protein in organs and tissues. Primary tracheal amyloidosis is rare. We report here a case of a 55-year-old man with tracheal amyloidosis hospitalized for acute respiratory insufficiency and with a history of recent episodes of pneumonia. Chest X-ray and chest computed tomography showed tracheal obstruction due to a...

Amyloidosis is a collection of diseases in which different proteins are deposited as insoluble beta-pleated sheets, disrupting organ function. Each precursor protein induces a separate spectrum of organ involvement, and different disease manifestations within the lung. Although autopsy data often demonstrate amyloid deposits in various compartments of the lung, few of the pathologic findings ar...

Eighty attempts at placing suction catheters in the left main bronchus were analysed by studying chest radiographs. When angled catheters were used via a tracheostomy tube the success rate was 75%; the rate fell to 15% when straight tubes were used through an orotracheal tube. Assessment and control of the tube length was found to be important to avoid kinking and subsequent obstruction of the ...

Aspirated foreign bodies present challenges to otolaryngologists. The major issues involve the accurate diagnosis and safe retrieval of the foreign body. The accurate diagnosis might be difficult because the initial choking incidents are not witnessed and the symptoms may mimic other common conditions. The author wishes to share our experience of managing an interesting case of 2.5 year-old-gir...
