[Response to the administration of corticosteroids in patients with chronic obstructive lung disease and asthma].

A spirometric study was performed in order to evaluate the response to the administration of 200 mg of salbutamol, just before and after the daily administration of 8 mg of triamcinolone, for an average period of 2 weeks, in 21 patients with chronic obstructive pulmonary disease or asthma. Eleven patients responded with a significant increase of FVC or FEV1 or FEF25-75%, after administration of corticoid. Ten patients did not respond. In average there was a significant increase of the FVC and VEF1 (p < 0.01) and of FEF25-75% (p < 0.05) after the administration of corticoid. There was no significant difference between the responders and not responders when the age, initial FVC, FEV1 and FEF25-75% were taken in consideration. A significantly greater number of responders to corticoid responded also to the bronchodilator with an increase of FEF25-75%. There was a significant negative correlation between the intensity of the response to corticoid versus bronchodilator measured with delta FEF25-75%. The administration of corticoid did not change the response to bronchodilator.

[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.

[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.
