background: congenital lobar emphysema, also called infantile lobar emphysema, is a respiratory disease that occurs in infants when air enters the lungs and cannot leave easily. it results from cartilage deficiency and bronchomalacia causing distal air trapping and respiratory distress. in this study, we present a case of endobronchial polyp mimicking congenital lobar emphysema. case presentati...

BACKGROUND In patients with bronchial obstruction, pulmonary function tests may not change significantly after intervention. The airflow asynchrony in both lungs due to unilateral bronchial obstruction may be applicable as a physiological indicator. The airflow asynchrony is reflected by the difference in the left and right lung sound development at tidal breathing. OBJECTIVES To investigate ...

process was impaired by inflammation.3,9 These observations were confirmed by means of gas analysis by Lindskog and Van Allen.A Collateral respiration was also demonstrated in relation to experimental segmental emphysema produced by valvular bronchial obstruction. Lobar emphysema followed valvular obstruction of lobar bronchi, but no emphysema resulted from this type of obstruction in the prima...

The aim of the current study was to retrospectively analyze clinical data concerning bronchostenosis or bronchial obstruction caused by endobronchial tuberculosis. Fifty-six cases were subjected to bronchoscopy and chest computed tomography to assess the prognosis of bronchostenosis and bronchial obstruction. Based on reliable and effective anti-pulmonary tuberculosis therapy, these conditions ...

BACKGROUND Allergic rhinitis and asthma may be associated, bronchial hyperreactivity (BHR) is quite common in AR patients. It has been reported that allergen bronchial challenge induces nasal inflammation. Methacholine (MCH) is a stimulus able to elicit BHR. There is no study that investigated the effect of MCH bronchial challenge on the nose. OBJECTIVE The aim of this study was to evaluate w...

OBJECTIVE To analyze the plain chest radiographic and CT findings of superficial endobronchial lung cancer and to correlate these with the findings of histopathology. MATERIALS AND METHODS This study involved 19 consecutive patients with pathologically proven lung cancer confined to the bronchial wall. Chest radiographs and CT scans were reviewed for the presence of parenchymal abnormalities,...

Clinical studies suggest that bronchial obstruction and emphysema increase susceptibility to lung cancer. We assessed the possibility of a common genetic origin and investigated whether the lung cancer susceptibility locus on chromosome 5p15.33 increases the risk for bronchial obstruction and emphysema. Three variants in the 5p15.33 locus encompassing the TERT and CLPTM1L genes were genotyped i...
