A total of 287 bronchoscopies were performed in 267 patients infected with the human immunodeficiency virus (HIV). Bronchoalveolar lavage (BAL) and transbronchial biopsies (TBB) were sequentially performed in the same lung, in all cases. Specimens were examined after routine laboratory procedures for microbiologic and histologic analysis. Age ranged from 16 to 78 (median 37.2); 228 were men (85.4%) and 39 were women. Dyspnea was the main symptom in 198 cases (69.0%) and interstitial infiltrates (diffuse or localized) were the most common findings at chest radiographs (179 patients, 62.4%). Endoscopic view was normal in 246 patients (85.7%). Mucosal lesions suggestive of Kaposi's sarcoma (KS) were visible in 12 cases (4.2%). BAL detected 97 infectious agents, simultaneous co-infection occurred in 3 cases. TBB identified 165 pathogens (9 of them in association), anticipating a better yield than BAL in the diagnosis of P. carinii (84 versus 51, respectively) and cytomegalovirus (35 v. 0). Biopsies were unique in establishing the appropriate diagnosis of extrabronchial cancer and describing inespecific pneumonitis. Altogether, a definite diagnosis was obtained by bronchoscopic examination (including endoscopic view, BAL and TBB) in 271 of 287 cases (94.4%). Infections were caused by P. carinii in 105 patients (36.6%), Mycobacterium sp in 40 (13.9%), cytomegalovirus in 35 (12.2%), C. neoformans in 13 (4.5%) etc. Malignancies (including KS) were found in 16 patients (5.6%). More than one pathologic process was present in 28 (9.8%). Nonspecific pneumonitis was diagnosed in 56 cases (19.5%) and normal lung in 20 (7.0%). Complications related to bronchoscopy were pneumothorax (8 patients, 2.8%), haemorrhage (8), thoracic pain (2) and distal pneumonia (2). Chest tubes were required in 4 patients, including one fatal case (mortality rate of 0.3%). Combining BAL and TBB results increases the diagnostic yield of bronchoscopy in AIDS, with a low complication rate. If both techniques are performed, a higher number of infectious agents and more multiple causes of pulmonary disease may be identified.

Objectives: Evaluate the results of the Brazilian Society of Tisiology and Pulmonary Medicine Board Examination and verify the factors related to acceptance. Planning: Retrospective analysis comparing scores obtained in practical and written examinations and acceptance to gender, years since graduation, years of pulmonary medicine practice, regional and national meetings attendance, place, and duration, as well as having or not attended residence or training programs. Population: Between 1992 and 1996, 199 candidates - 81 females and 108 males - took the board examination. Results: In this period, 54.3% of the candidates were approved. Mean written score was 6.27 ± 0.95 for the approved candidates and 4.30 ± 0.76 for those who were not approved (p = 0.0001, t test). Mean practical score was 7.18 ± 0.92 versus 5.17 ± 1.38 (p = 0.001). The overall mean of the written score was significantly lower than that of the practical score (53.78 ± 13.16 x 62.62 ± 15.32, p < 0.001). Univariate analysis showed that the approved group had fewer years since graduation (p = 0.001), fewer years of pulmonary medicine practice (p = 0.01); lower training attendance for a shorter period (p = 0.01), and a higher frequency of residence attendance for a longer period (p < 0.001) in the approved group. Logistic regression showed that residence (p = 0.002) and place of residence (p = 0.006) were the only predictive factors for approval. Multiple linear regression showed that only residence (coefficient 2.26, p = 0.016), place of residence (4.43, p = 0.002), and training (-1.97, p = 0.047) predicted the overall board score. Conclusion: The efficacy of the board exmination is hereby proven, since it accepts candidates with better medical background (residence). Some medical education methods, such as years of practice, meeting and training attendance need to be revised, since they do not determine approval.
