[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.

[Bronchioloalveolar carcinoma in a young woman].

Bronchioloalveolar carcinoma is an infrequent malignant lung tumor, specially in patients younger than 50. Diagnosis is difficult and usually late, because its clinical and radiologic features are similar to other lung diseases and because its poor histopathologic differentiation from other primitive o metastatic adenocarcinoma. We report a case of multinodular, diffuse and bilateral bronchioloalveolar carcinoma in a young woman without previous lung disease which suspected diagnosis was by broncho-aspirated cytology and open lung biopsy was necessary for its confirmation.

[Can we improve the prevention of tuberculosis? Analysis of the application of chemoprophylaxis].

To analyze the situations that make chemoprophylaxis for tuberculosis difficult. One hundred twenty-eight patients consecutive (106 HIV negative and 22 HIV positive) diagnosed of tuberculosis (TB) were studied. The patients were interviewed and a questionnaire was filled out in order to identify risk groups and determine what steps had been taken to prevent TB. In the HIV negative group, 63 (57.8%) had at least one risk factor. The most common were contact with persons with active TB (31.1%), former TB (15.1%), rapid weight loss or chronic malnutrition (13.2%) and residence in closed institutions (5.6%). Of the 51 (48.1%) for whom evaluation of chemoprophylaxis was indicated, 43 (84.3%) had been examined by a physician within the past five years; only 10 (23.3%) of them, however, had been checked for TB and isoniazide had been prescribed for only 4 (9.3%). In the HIV positive group, 13 (72.2%) of those for whom evaluation of chemoprophylaxis was indicated had been seen by a physician; 12 (97.7%) of them were given tuberculin tests checked for TB and isoniazide was prescribed for 4 (30.7%). None of the patients in either group who were prescribed a full course of prophylaxis actually took the drug enough. Most HIV negative patients for whom evaluation of chemoprophylaxis was indicated had been examined by a physician in the five years before disease was detected; less than a quarter of them were checked for TB, however. This situation is probably a consequence of the structure of health care in Spain as it affects TB control. Nearly all the HIV positive patients were checked for the disease, as they benefited from protocolized health care.

[Hereditary hemorrhagic telangiectasia at an internal medicine service: study of 12 patients].

Hereditary hemorrhagic telangiectasia (HHT) is a hereditary dominant autosoma clinical entity characterized by repeated hemorrhages (being epistaxis the more frequent) and telangiectasia in skin, mucosa and internal organs. Incidence in Europe is 1,2 per 100,000 pop. We discuss the experience of an Internal Medicine Department (Arnau de Vilanova Hospital), during 10 years, in which 12 patients were diagnosed. With the aim to provide more information about this rare disease. There was no predominant sex and the age of onset was very variable. All patients referred at admission past history of hemorrhages (either the patient him/herself or some relative), or were suffering it at admission. Except one patient, all of them showed telangiectasias in skin and mucosa. In five of them telangiectaias were found in upper gastrointestinal tract, in two there were localized on the tracheobronchial tree and one patient had teleangiectasia in liver. Three patients were diagnosed of pulmonary arteriovenous fistula (PAVF). The clinical, diagnostic and therapeutic aspects of this disease are reviewed.

[Familial outbreak of pulmonary tuberculosis].

A study of 5 patients diagnosed as having pulmonary tuberculosis during a period of 14 months is presented. 3 of them are members of the same family of 7 and the other 2 are closely related. This study calls our attention to the need for carrying out contacts evaluation, relative or not, and for chemoprophylaxis. The presentation of microepidemyes in relation to the decrease of the prevalence was also observed.
