RESUMO
In this study, Mycobacterium tuberculosis complex was detected by BD ProbeTec ET system in 4716 respiratory and 167 nonrespiratory samples [mostly (98%) smear negative). Sensitivity, specificity, positive and negative predictive values were 81.8%, 98.3, 85.1 and 97.9 for respiratory and 100%, 96.2, 64.7 and 100, for nonrespiratory samples, respectively. Among 149 (3.1%) ProbeTec DTB positive and culture negative samples, 72 (65 respiratory and seven nonrespiratory) (48.3%) were recovered from the patients who were evaluated as having TB infection. The system has been found as useful in early diagnosis of tuberculosis infection in association with the clinical, radiological and histopathological findings.

A 61-year-old woman presented with an eosinophilic pleural effusion, secondary to transdiaphragmatic intrapleural spread of an hepatic hydatid cyst. Right posterolateral thoracotomy and frenotomy revealed a loculated pleural effusion associated with a 10 x 8 cm hydatid cyst in the posterior segment of the liver. Hydatid disease should be included in the differential diagnosis of eosinophilic pleural effusions in endemic regions.
