Out of the two air dried smears, one was stained with May Grunwald Giemsa and the other with Gabbot's method for AFB. The smears were screened for malignant cells and a cytological diagnosis was made. The cytological diagnosis was correlated with the histopathological diagnosis. The data ...
CONCLUSION: Albeit of very rare occurrence, presence of epithelioid cell granuloma and Langhans' giant cells, along with demonstration of AFB in routine sputum cytology, is capable of providing a conclusive diagnosis in appropriate clinical context, obviating the need of additional investigation....
Results: One patient in each group was SS positive (SSP) for Acid Fast Bacillus (AFB). The SC was positive (SCP) for MTB in 9 patients :4 HIVpos patients and 5 HIVneg patients with non significant p value. The 2 patients who had SSP were also the only one with parenchymal ...
1). We compared the positive culture yield for AFB between sputum aspirate specimens obtained during examination of the central airway and bronchial washing specimens obtained by wedging into bronchi with the most severe lesions. Additionally, we assessed the quality of sputum aspirate specimens in ...
(2) This study is the first to report that SBL affected the key breakpoints and the risk factors for false-negative Xpert®, as well as the evaluation of the reliability of RIF resistance detection based on the Ct value, A suggestion was made to resegment the Ct value. Conclusions ...
Smear grading of SPPTB cases is as follows: 1+ (10–99 acid-fast bacilli (AFB) in 100 fields), 2+ (1–9 AFB/field in at least 50 fields), and 3+ (>10 AFB/field in at least 20 fields). Whatever the clinical form of TB, all patients should undergo two phases of treatment: ...
OBJECTIVES: To measure the diagnostic utility of sputum AFB in Ontario. METHODS: All patients' first AFB smears submitted to Public Health Ontario Laboratories during 2012–2014 were compared against final cultures. Diagnostic test characteristics were calculated for AFB smears in predicting TB and NTM...
Case Report: A 28-year-old woman was admitted with complaints of ankles pain, fever, noc-turnal sweating, dyspnea and productive coughs. Patchy consolidations were seen on her chest x-ray and three sputum positive acid-fast bacillus (AFB) smears were reported in her investigations. The ...
Test characteristics for NTM were: specificity 97.6%, negative predictive value 86.9%, sensitivity 14.7%, positive predictive value 51.0% in the entire population. CONCLUSIONS: Sputum AFB performed poorly in predicting TB because of the large proportion of AFB-positives caused by NTM (51.0%) and ...
Thirty-eight were found positive for AFB on sputum microscopy after induction. Conclusions: Hypertonic saline induction produces better quality and adequate sputum, thereby increasing yield of smear positive pulmonary tuberculosis. 展开 关键词: Research Report Clinical Research Target Population Tuberculosis ...
