Background: Inflammation in chronic obstructive pulmonary disease (COPD) is characterised by increased neutrophilic infiltration of the airways. Cilomilast, a novel selective phosphodiesterase 4 inhibitor in clinical development for COPD treatment, exerts anti-inflammatory effects. The ability of cilomilast to inhibit the release of neutrophil chemoattractants such as tumour necrosis factor (TN...

Transbronchial lung biopsy (TBLB) is a well-recognized diagnostic technique in diffuse interstitial lung diseases, but it is not considered to be the first choice in investigation of solitary pulmonary nodules (SPN). The main idea of this study was to increase the sensitivity of bronchoscopy using multiple techniques, especially TBLB, thus to avoid more aggressive diagnostic procedures. The obj...

The sensitivity of all fiberoptic bronchoscopic techniques in case of a peripheral lung cancer is 69%. In the study, it was aimed to assess the contribution of broncoalveolar lavage (BAL) performed before and after standard biopsy procedures in the diagnosis of peripheral lung cancer. The patients with peripheral lung lesion in radiology, and normal bronchoscopic findings were included in the s...

The classification of squamous cell carcinomas, based on cellular differentiation features, includes the poorly differentiated epidermoid carcinomas and well-differentiated epidermoid carcinomas. The histogenetic cytologic data clarify conventional cytodiagnosis of poorly differentiated epidermoid carcinomas and poorly differentiated adenocarcinoma, and also eliminate other categories such as l...

Objectives: Endocytoscopy is a new endoscopic imaging device for in vivo visualizing cellular structures. The aim of this study was to observe lung cancer cells using an endocytoscopy and compare them with the microscopic findings. Methods: Between July 2009 and April 2011, 12 patients with lung cancer (5 with squamous cell carcinoma, 4 with small cell carcinoma and 3 with adenocarcinoma) and 3...
