Capacidad del diagnostico clínico presuntivo y validez del estudio del exudado pleural en pacientes con derrame pleural inespecífico
Abstract
To identify the validity of clinical diagnostic and the analysis of pleural exudate in the diagnosis of inespecific pleural effusion, we reviewed the clinical records of 40 adults, 61% (24 male and 16 female) with an average age of 45 ± 17 years. Pleural biopsy was the gold standard. The clinical diagnosis were: pleural metastatic cancer (34%) and pleural tuberculosis (TBC) (27%). Pleural effusions where: lymphocitic (68%), neutrofilic (27%) and eosinofilic (5%). Histologic types inespecific cronic pleuritis (56.1%) pleural TBC (22%) and pleural metastatic cancer (12.2%). The comparision test show for pleural TBC a Kappa: 0.47, for pleural cancer was (Kappa low: 0.18). The validity tests show for pleural The the greater sensitivity for the Iymphocitic count (44%) and the greater specificity was for the eosinotilic count (97%) for pleural metastatic cancer the best sensitivity was for neutrofilic exudate (60%) and the greater percentage of specificity (97%) was for eosinofilic predominium. The predictive positive value for metastatic cancer and THC was (50%) and (60%) respectively the odds ratio between the pleural exudate and pleural biopsy for metastatic cancer and THC was probably casual.
