Its yield would be increased combined with the use of bronchial lavage
, brush cytology, and endobronchial biopsy.
was performed inside the accessory bronchus with the aim of cytologic examination was normal.
A Ziehl-Neelsen stain for acidoresistant bacteria was negative in three sputum samples and negative in one bronchial lavage
The clinical specimens included: bronchoalveolar lavage (BAL) (n = 10), bronchial lavage
(BL) (n = 6), biopsy (n = 4), and cerebrospinal fluid (CSF) (n = 24).
Fungal cultures of lung biopsy, lymph node, sputum, and bronchial lavage
specimens were negative.
After bronchoscopy, 2 of 3 bronchial lavage
(BAL) samples were found to be positive for acid-fast coccobacilli by microscopy, and rapidly growing, deep orange mycobacteria grew in all 3 cultures.
The bronchial lavage
specimen was inoculated onto 5% sheep blood agar, chocolate agar, and MacConkey agar for isolation of routine bacteria.
If samples are needed, a bronchial lavage
may be performed for analysis.
To better understand the distribution of miRNA in body fluids, we examined the spectrum of miRNA in 12 fluids: plasma, saliva, tears, urine, amniotic fluid, colostrum, breast milk, bronchial lavage
, cerebrospinal fluid, peritoneal fluid, pleural fluid, and seminal fluid from normal individuals.
Mucosal biopsies were obtained from different sites and bronchial lavage
fluid was also taken.
Microscopic examination of wet preparations of the bronchial lavage
fluid showed numerous ciliated B.
One case report has described the measurement of ACTH in bronchial lavage
as confirmation of the production of ACTH by a lung carcinoid, but it will need to be confirmed in larger studies (15).
