background: the frequency of invasive opportunistic mycoses has increased significantly over the past decades especially in immunocompromised patients. invasive aspergillosis (ia) has become a major cause of morbidity and mortality among these patients. as bronchoalveolar lavage (bal) fluid samples are generally useful specimens in the diagnosis of invasive pulmonary aspergillosis (ipa), this s...
OBJECTIVE To assess the diagnostic yield of fibreoptic bronchoscopy and bronchoalveolar lavage (BAL) compared to gastric aspiration (GA) in children with probable pulmonary tuberculosis (TB). METHODS Children with probable pulmonary TB were subjected to bronchoscopy, BAL and gastric aspiration. The samples were examined for acid fast bacilli (AFB) on smear. RESULTS A total of 52 children un...
Objective: To compare the mycobacteriological yield from self-expectorated sputum (SP), gastric lavage (GL) and bronchoalveolar lavage (BAL), in children with pulmonary tuberculosis (TB). Methods: Twelve children with cultureor PCR-positive pulmonary TB were retrospectively enrolled in this study. These patients had undergone SP collection, GL and/or BAL through flexible bronchoscopy. Positive ...
Pulmonary Alveolar Proteinosis (PAP) is a rare syndrome in the paediatric age group and characterized by intra-alveolar accumulation of proteinaceous phospholipid-laden material called surfactant. The diagnosis is made by High Resolution Computed Tomography (HRCT) chest which shows characteristic crazy paving appearance and diagnosis confirmed by Bronchoalveolar Lavage (BAL). We report two case...
Background and purpose: Respiratory failures are common diseases among different populations. Pneumocystis jirovecii colonization causes respiratory failure in children and adults with AIDS and patients with predisposing factors of immunosuppression including malignancies, organ transplant, inherited immune deficiencies and immunosuppressive agents. The aim of this study was to evaluate the eff...
This study assessed the effect of bronchoalveolar lavage (BAL) on nonspecific bronchial responsiveness in 31 patients. Of these, 20 had airflow obstruction; 11 control subjects had normal pulmonary function. Bronchial responsiveness to methacholine, expressed as the dose of inhaled methacholine required to provoke a 20 percent fall in forced expiratory volume in one second (PD20 FEV1), was meas...
As for many clinical tools, there is at the present time no clear agreement on the appropriate clinical use of BAL. Undoubtedly, the recent and encouraging clinical experiences with BAL for diagnosis of opportunistic infections in the immunocompromised patient have encouraged a universal acceptance and interest in BAL. Because of the low morbidity of the lavage procedure and the significant yie...
The effect of heavy, habitual marijuana use compared with tobacco smoking on the composition of bronchoalveolar and peripheral blood lymphocytic phenotypes was examined. Bronchoalveolar lavage (BAL) and peripheral blood (PB) samples were taken from 14 nonsmokers (NS), 14 tobacco smokers (TS), 19 heavy, habitual marijuana smokers (MS), and 9 marijuana and tobacco smokers (MTS). In BAL fluid, mar...
