RESUMO
We conducted a retrospective analysis of the epidemiological, etiological, clinical and radiological characteristics, and mainly of those related to the diagnosis and treatment, of all the patients with radiological criteria of solitary pulmonary nodule (SPN) studied in our environment during a period of six years (1984-1989). The incidence of SPN was 3.1% (123/3953). Among the 117 cases of filiated etiology, 83 (71%) were malignant and 34 (29%), benign thoracotomy was used as diagnostic method in 11 (32%) benign cases and in 8 (9.6%) malignant cases. Due to several causes, only 31 out of the 75 (41.3%) malignant nodules diagnosed prior to the thoracotomy underwent resection surgery. According to the selection criteria applied in our medium, a high number of the SPN were malignant; in most of these cases, the diagnosis was established without the need of thoracotomy and in less that half of them, curative surgery was attempted.

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.
