Influence of diuretics on the concentration of plwural and other components of pleural transudates in patients with heart failure. Clinical utility of polymerase chain reaction for diagnosis of smear-negative pleural tuberculosis. With these parameters a sample size of 34 patients was estimated for this study.

This prevalence is similar to that found in TBP studies in Spain 17 and higher than the prevalence of TB in the studies carried out in the majority of countries with GDP higher than in our country 12 and this could be explained by an epidemiological transition in our population with an increase in the frequency of neoplastic diseases and a reduction in the frequency of infectious diseases.


There were two false positives for RT-PCR, one with pleural mesothelioma and the other with chronic pleurap with mesothelial hyperplasia. Int J Tuberc Lung Dis, 7pp.

Predictive factors for pleural drainage in children with parapneumonic pleural effusion

These values show lower sensitivities than the RT-PCR, confirming once again the need to have a combined reference method since these tests alone could not rule out the presence of pleural tuberculosis.
