[High resolution computerized tomography in pulmonary tuberculosis with negative sputum bacilloscopy].

CONTEXT: Pulmonary tuberculosis with negative sputum bacilloscopy involves diagnostic difficulties when there are not available liquid culture media due to the slow growth of Mycobacterium tuberculosis in the traditional culture media, and also due to the need for carrying out invasive examinations. OBJECTIVE: Evaluate the high resolution computerized tomography findings (HRCT) in patients with pulmonary tuberculosis and negative bacilloscopy of sputum. METHOD: Prospectively 28 patients (12 with active tuberculosis and 16 with inactive tuberculosis) were evaluated through HRCT, assessing the following findings: centrolobular nodules, multiple branched linear structures, macronodules, cavitation, consolidation, enlargement of interlobular septums, ground-glass change, bronchiectases, emphysema, broncovascular distortion, fibrotic changes, calcified mediastinal adenopathies, parenchymous calcification, pleural enlargement, and pleural effusion. RESULTS: The findings that were associated significantly to the active disease were: consolidation (67%), macronodules (67%) and centrolobular nodules (67%). The presence of centrolobular nodules and/or consolidation had a sensitivity of 83% and a specificity of 87%. The findings significantly associated to inactive disease were bronchiectases (87%) and broncovascular distortion (62%). CONCLUSION: Our results support the value of HRCT in patients with pulmonary tuberculosis and negative sputum bacilloscopy, since the finding of centrolobular nodules and/or consolidation has good sensitivity and specificity for the diagnosis of active pulmonary disease.

[Relationship between dyspnea and quality of life with body mass index and pulmonary function in patients with chronic obstructive airways disease and emphysema].

BACKGROUND: We aimed to evaluate the differences in pulmonary function, quality of life (CVRS) and dyspnea in patients with chronic obstructive pulmonary disese (COPD) and emphysema according to the body mass index (BMI). Moreover, we analyzed the relation between BMI, pulmonary function, CVRS and dyspnea. PATIENTS AND METHOD: This was a prospective, 12-months study including 20 patients with COPD and emphysema. They were classified in group A (BMI < 21 kg/m(2) group B (BMI >= 21 kg/m(2)). We performed pulmonary function tests and determined the levels of dyspnea and CVRS according to a scale of dyspnea and a CVRS questionnaire. RESULTS: Seven patients had a BMI < 21 kg/m(2) and it was >=21 kg/m(2) in 13 patients. DLCO in group A patients was lower than in group B. After a multiple regression analysis, the FVC accounted for 52% of dyspnea variability. Both PEM and dyspnea were the parameters that better predicted the CVRS. CONCLUSIONS: Patients with COPD and emphysema with a VMI < 21 kg/m(2) have a lower DLCO than patients with a BMI >= 21 kg/m(2). In our patients, dyspnea sensation depended on the FVC. In addition,the CVRS depended on dyspnea sensation and PEM.

[Miliary, ganglionar, pancreatic and costal tuberculosis. Clinical presentation and literature review].

A 42-year-old man was admitted to the hospital with fever, abdominal pain and miliary radiological pattern. The amylase and lipase in serum, and the amylase in urine were increased. The tuberculin skin test was negative. The thoracic and abdominal CT scan showed costal affectation, multiple focal hepatic lesions and large necrosing peripancreatic lymphadenopathies. The transbronchial biopsy and the pancreatic punction demonstrated granulomatous necrotic lesions, and M. tuberculosis grew in the bronchial washing culture. The specific treatment normalized the pulmonary, costal and pancreatic lesions.
