To check the possible existence of long-term pulmonary functional sequelae in patients with pneumonia due to Mycoplasma pneumoniae, 17 patients who showed evident spirometric disorders during the recovery from the acute phase of a pneumonia due to Mycoplasma pneumoniae were studied. In the acute phase of the disease, 7 patients showed a ventilatory restriction, 6 of them had an obstructive pattern while in four patients a mixed pattern was observed. After a latency period, which mean length was 39 months, it was seen that there was a return to normal values of the spirometric conventional parameters initially altered in all cases. However 5 patients (33%) who did not smoke, showed a significant decrease on the maximum flows at low volume. These results suggest that in a high percentage of adult patients, as has been previously described in children, pneumonia due to M. pneumoniae could leave as a sequelae the persistent affectation of small airway.

With the aim of testing the cost-effectiveness of diagnostic fiberbronchoscopy in pleural effusions, the results obtained in a study of 46 patients in whom pleural effusion was the only indication for this diagnostic technique was analyzed. Patients were divided into two groups based on whether they presented pleural effusion of unkown ethiology (group A) or non-localized primary metastatic effusion (group B). Two out of 28 patients in group A, and 5 out of 18 in group B were diagnosed by means of fiberbronchoscopy. It is concluded that given the good tolerance and low morbidity of this exam, the diagnostic cost-effectiveness justifies its performance in such situations. Possible modifications in the indications that could influence its utility are discussed.

149 patients suffering from hemoptysis of unknown origin who presented a normal chest X-ray were followed up, in order to evaluate their prognosis, during a mean period of 12.6 months after the initial study which included fiberoptic bronchoscopy. During this time, 24 patients (16.1%) presented new episodes of hemoptysis without radiological modifications; a second fiberoptic bronchoscopy carried out in 13 of these patients did not contribute with any new diagnostic data. One patient was diagnosed of pulmonary thromboembolism after persistent hemoptysis and two others of bronchial carcinoma 4 and 30 months after the initial fiberoptic bronchoscopy when the chest X-ray had already suffered significant changes. These data confirm that short term prognosis of cryptogenetic hemoptysis is generally favourable when the fiberoptic bronchoscopy is negative. The fact that a high percentage of these patients (37%, 55/149) had previously suffered pulmonary tuberculosis and/or inflammatory-scar type localized endobronchiolar lesions suggests that sequelae of these diseases, not observed in the X-ray, could play an etiological role in the bleeding.
