To contribute to the phylogenetic evaluation of the river dolphin, the morphology of the tracheobronchial tree of the Ganges river dolphin was analyzed according to Nakakuki's fundamental bronchial tree model of mammals. In the right lung, the bronchial tree consists of the tracheal bronchus, five lateral series bronchi, three dorsal series bronchi and one ventral series bronchus. In the left l...

Bronchogenic cysts are developmental errors of the tracheobronchial tree. Various clinical presentations from incidental detection to symptomatic have been described but presenting as acute bronchial asthma is relatively rare. A 3-year-old male child repeatedly presented with asthmatic attacks. Initially treated and evaluated for foreign body. Contrast enhanced computed tomography (CECT) scans ...

In asthmatic subjects there is a pronounced diurnal variation in bronchial responsiveness. If this phenomenon is due to variation in factors that control drug delivery, then it should be paralleled by a similar variation in competitive antagonist blockade. In order to study this possibility, we performed the methacholine challenge test and after 45 minutes, administered atropine by inhalat...

BACKGROUND Computed tomographic (CT) airway lumen narrowing is associated with lower lung function. Although volumetric CT measures of airways (wall volume [WV] and lumen volume [LV]) compared to cross sectional measures can more accurately reflect bronchial morphology, data of their use in never smokers is scarce. We hypothesize that native tracheobronchial tree morphology as assessed by volum...

Tracheobronchial submucous glands can be considered the pulmonary equivalent of minor salivary glands and therefore they can develop most of the tumours originated in these. Nevertheless, in spite of the wide distribution of this kind of glands along the tracheobronchial tree, pulmonary salivary gland-like neoplasms are not very frequent. Among them, the most frequent are mucoepidermoid and ade...

Granulomatosis with Polyangitis (GPA), previously known as Wegener’s Granulomatosis, is a form of anti-neutrophil cytoplasmic antibodies (ANCA)-associated vascuilitis predominantly involving the upper and lower respiratory tract and kidneys. Tracheobronchial involvement in GPA can have varied manifestations which include airway inflammation, mucosal granulomas, tracheobronchial stenosis, trache...
