Utility of Reflexive Gomori Methenamine Silver and Acid-Fast Bacillus Staining on Bronchoalveolar Lavage Specimens

Utility of reflexive gomori methenamine silver and Acid-fast bacillus staining on bronchoalveolar lavage specimens.

OBJECTIVE Reflexive testing of bronchoalveolar lavage (BAL) specimens with Gomori methenamine silver (GMS) and acid-fast bacillus (AFB) stains is not routinely performed by most institutions. Instead, these stains are usually ordered to evaluate for the presence of fungal elements and/or acid-fast organisms if initial histopathologic assessment suggests the presence of these pathogens. Our inst...

comparison of gomori’s methenamine silver method with pcr technique on oral swab, bronchoalveolar lavage and lung ho-mogenate specimens in detection of pneumocystis

background: pneumocystis carinii is one of opportunistic organisms especially in immuno-compromised patients. for years, diagnosis of pneumocystis pneumonia (pcp) has relied on microscopic visualization of organism in specimens obtained from the lung either by bronchoalveolar lavage (bal) or by induction of sputum, but failed to provide efficient diagnosis. the aim of this study was to compare ...

Comparison between real-time PCR, conventional PCR and different staining techniques for diagnosing Pneumocystis jiroveci pneumonia from bronchoalveolar lavage specimens.

Between January 2002 and July 2003, 173 bronchoalveolar lavage (BAL) specimens from 150 patients (19 HIV-infected and 131 non-HIV-infected patients) were evaluated for identification of Pneumocystis jiroveci (formerly known as Pneumocystis carinii f. sp. hominis) using staining techniques, conventional PCR (mtLSUrRNA gene) and real-time PCR (MSG gene). Test results were compared to Pneumocystis...

Immunoglobulin abnormalities in bronchoalveolar lavage specimens from amiodarone-treated subjects.

Bronchoalveolar lavage--obtaining biologic specimens from the respiratory tract surface.

Dating to fifth century BCE in Greece and the Hippocratic Movement of Physicians that created the beginnings of Western Medicine, a combination of bodily fluids and discharges, termed humors, described how the human body functioned. Among the four humors, phlegm was one and was connected to old age and winter (1). Consider that respiratory secretions in the elderly might reflect the cumulative ...
