Although a biopsy may need to be performed in complicated patients, bronchoalveolar lavage (BAL) is an important adjunct to the diagnosis of pulmonary and disseminated fungal infections. Culture is the gold standard for diagnosis in many instances, but cytologic and morphologic analysis is often diagnostic. Although newer molecular and antigen techniques may be applied to BAL samples, the role ...

We present a case of an immunocompromised woman with fever, pulmonary infiltrates and multiple bronchoalveolar lavage (BAL) cultures positive for Penicillium citrinum with a concomitant high BAL galactomannan level. We report the results of Aspergillus galactomannan testing performed on culture supernatants from her P. citrinum strain that confirmed the suspected cross-reactivity. Finally, we d...

s:696:"Pulmonary alveolar microlithiasis (PAM) is classified as an elective dysmetabolic thesaurotic pneumoalveolitis and characterized by the presence within the alveoli of the lungs of myriad of tiny calculi. The classic presentation of the chest radiography is unmistakable with multiple small "sand-like" opacities diffusely involving both lung fields. We present a case of male infertility fo...

An unbalanced oxidative stress is thought to be an important element in the pathogenesis of diffuse fibrosing alveolitis (DFA). The purpose of our study was to investigate the role of reactive oxygen metabolites (ROMs) released from cultured bronchoalveolar inflammatory cells (BA-cells) on glutathione oxidation. We studied bronchoalveolar lavage samples from 10 healthy controls and from 20 pati...

Acute rejection (AR) is an important complication that can occur after lung transplantation and constitutes a risk factor for bronchiolitis obliterans syndrome, which is characterised by a neutrophilic airway inflammation. The specific aim of this study was to investigate the role of interleukin (IL)-17, which promotes chemotaxis of neutrophils by inducing IL-8 production, in AR. Cell different...

In the last few years many chemically injured patients have been visited throughout the country in order to investigate the late respiratory complications of sulfur mustard. 35 patients who were previously admitted for mustard poisoning underwent complete clinical examination as well as spirometry, fiberoptic bronchoscopy (FOB), Bronchoalveolar lavage (BAL), and trans bronchial lung biopsy...

Cell counting of bronchoalveolar lavage (BAL) fluid is performed manually in routine practice. This has both methodological and inherent errors; however, the accuracy and suitability of automated counting devices have been questioned. In this study, a Coulter Counter D Industrial model was calibrated and then used to measure the total cell count in unprocessed bronchoalveolar lavage fluid, and ...

BACKGROUND Sarcoidosis is a chronic granulomatous lung disease of unknown origin. The accumulation of activated T cells at sites of inflammation represents an early stage in granuloma formation. Since mechanisms governing the normal resolution of inflammatory processes are poorly understood, this study aimed to investigate the apoptotic phenotype of peripheral blood and lung T lymphocytes from ...

We describe a research technique for fiberoptic bronchoscopy with bronchoalveolar lavage (BAL) using manual hand held suction in order to remove nonadherent cells and lung lining fluid from the mucosal surface. In research environments, BAL allows sampling of innate (lung macrophage), cellular (B- and T- cells), and humoral (immunoglobulin) responses within the lung. BAL is internationally acce...

The aim of this study was to investigate the possibility of distinguishing between patients with similarities in clinical presentation, suffering from three frequently occurring interstitial lung diseases, by means of discriminant analysis, using a number of selected variables derived from bronchoalveolar lavage fluid (BALF) analysis. The study involved all 277 patients, who had an initial bron...
