[Response of airflow to the administration of bronchodilator agents in patients with chronic obstructive lung disease or asthma].

Spirometric tests of 30 patients with chronic obstructive pulmonary disease (COPD) or asthma were evaluated just before and 15 minutes after the administration of 200 mg of salbutamol by inhalation. All patients had a significant increase os their airflow after the bronchodilator administration. In 15 patients the increase of FEV1 was greater than 13% (Group I) and in other 15 patients the increase of FEF25-75% was greater than 23% (Group II). The two groups showed differences with respect to the initial FEV1, and FEF25-75% (% of predicted), with values significantly lower (p 0.01) in Group I. There was no significant difference between the two Groups concerning the age, sex and the initial FVC (% for predicted).

[Lymph node tuberculosis in adults].

Tuberculous lymphadenitis is a form of extrapulmonary tuberculosis that was observed in 8.4% of all cases with tuberculosis in our series. In all instances the organism isolated was M. tuberculosis. There was a high rate of PPD positiveness. The chemotherapy yielded good results. The evolution was satisfactory in 75% of the patients treated for six months.

[Tuberculous pleural effusion: clinical and laboratory evaluation].

Clinical data concerning 44 patients with pleural tuberculosis are presented. The average age was 35 years. The main symptoms were fever (41/44), chest pain (41/44) and weight loss (34/44). In all but one case the pleural effusion was unilateral without preference for one or other hemithorax. In ten patients (23%) parenchymal lesions could be recognized on chest roentgenograms. Three patients had coexisting active pulmonary disease with positive sputum culture. Forty-nine pleural biopsies were performed in 44 patients. The culture of pleural tissue was positive in 75%, and culture of pleural fluid in 22.5%. The pleural fluid was exudative with fluid-to-serum ratios of protein and LDH exceeding 0.5 and 0.6 respectively. The cellular characterization of pleural fluid has demonstrated predominance of lymphocytes and scarcity of mesothelial cells. The patients received adequate treatment with excellent results, exhibiting an increased weight, increased hemoglobin and decreased ESR. The development of residual pleural thickening occurred in 23 out of 44 cases.

[Bronchial stenosis of tuberculous etiology: pathogenesis and treatment].

Four cases of bronchial stenosis as an unusual complication of tuberculosis are described. In the first case, a 18-year-old woman, the bronchial stenosis resulted from cicatrization of a primary focus. The X-ray examination showed no pulmonary lesion and she did not receive any specific treatment for tuberculosis. In other three patients the bronchial stenosis was due to active disease, and there were acid-fast bacilli in the sputum. They received treatment for tuberculosis which resulted in resolution of stenosis in one of them while in the other two the fibrotic bronchial stenosis persisted.

[Foreign-body aspiration in adults].

Proximal airway obstruction and acute life-threatening asphyxia is the most important complication of foreign body aspiration. Small foreign bodies that transverse the larynx may be initially asymptomatic appearing serious respiratory disturbances only later. Three patients with different clinical evolutions are reported and the diagnostic and therapeutic approaches, discussed.

[Alveolar proteinosis: report of 4 cases].

Pulmonary alveolar proteinosis is a rare disease characterized by the filling of the alveolar spaces of the lung by a PAS-positive lipoproteinaceous material. Despite the clear characterization of this material, the etiopathogenesis of the disease remains obscure. We present four patients who were admitted in our Department over the last seven years. The diagnosis was confirmed by lung biopsy in all cases. Three patients improved after bronchoalveolar lavage. Spontaneous remission was observed in one case.

[Septic pulmonary embolism with primary focus in the middle ear].

A case of septic pulmonary embolism is presented in which the primary site of infection was the middle ear. The implicated bacteria were aerobics both Gram positive and Gram negative and anaerobics. There were 8 different agents isolated from blood cultures. The cultures of urine and sputum were also positive. The patient received a broad spectrum antibiotic therapy and a surgical exploration of the initial site of infection was performed. A favorable response was observed after 40 days of treatment with antibiotics.
