Aspirin causes bronchoconstriction in aspirin-intolerant asthma (AIA) patients by triggering cysteinyl-leukotriene (cys-LT) production, probably by removing PGE2-dependent inhibition. To investigate why aspirin does not cause bronchoconstriction in all individuals, we immunostained enzymes of the leukotriene and prostanoid pathways in bronchial biopsies(More)
BACKGROUND The influence of the technique of thymectomy on late results in the treatment of myasthenia gravis remains controversial. METHODS Results of 60 basic transsternal thymectomies and 58 extended transsternal thymectomies were compared. Both positive results (complete remissions or improvement) and negative results (no improvement, deterioration,(More)
OBJECTIVES The aim of the study was to assess the diagnostic yield of the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in restaging of the non-small-cell lung cancer (NSCLC) patients after neo-adjuvant therapy. METHODS In a consecutive group of NSCLC patients with pathologically confirmed N2 disease, who underwent(More)
Churg-Strauss syndrome (CSS) is a rare, systemic, necrotizing, small- and middle-sized vessel vasculitis which is accompanied by blood eosinophilia, eosinophil infiltration of various tissues, and bronchial asthma. The lungs are the organs most often involved in CSS. The aim of this study was a retrospective evaluation of the pulmonary findings in chest(More)
OBJECTIVES This prospective study aimed to assess the diagnostic yield of the combined approach - endobronchial (EBUS) and endoscopic (EUS) ultrasound-guided needle aspiration (combined ultrasound-needle aspiration (CUS-NA)) in the radiologically normal mediastinum in non-small-cell lung cancer (NSCLC) staging. METHODS CUS-NA was performed simultaneously(More)
OBJECTIVE The aim of the study was to assess the diagnostic yield of the endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-NA) in the mediastinal staging in non-small cell lung cancer (NSCLC) patients. METHODS Consecutive NSCLC patients with enlarged or normal mediastinal nodes on CT scans underwent EBUS-NA. All patients with negative(More)
BACKGROUND Regulation of prostaglandin synthesis and the activation of human airway fibroblasts associated with the remodeling of the bronchi play an important role in asthma. OBJECTIVE We sought to assess the cyclooxygenase pathways in airway fibroblasts of patients with bronchial asthma. METHODS Generation of prostaglandin E(2) (PGE(2)) and(More)
We have recently shown that oral aspirin provocation leads to an increase in LTE4 and a reduction in 11-dehydro-TXB2 levels in urine of patients with aspirin induced-asthma (AIA). To test the hypothesis that cyclooxygenase inhibition and an enhancement of cysteinyl-leukotriene production occurs in the lungs of patients with AIA, we examined the eicosanoid(More)
We have shown that inhalation of lysine aspirin enhances leukotriene production in the lungs of patients with aspirin-induced asthma (AIA). To assess the specificity of this reaction, we compared two well-matched groups of patients: eleven with AIA versus 14 asthmatics tolerant to aspirin (ATA). All subjects underwent bronchoalveolar lavage (BAL) with(More)
