[Kidney failure as a complication of the treatment of pulmonary paracoccidioidomycosis]. / Insuficiência renal como complicação do tratamento da paracoccidioidomicose pulmonar.

Sulfadiazine is one of the drugs of choice in the treatment of paracoccidioidomycosis. Side effects are uncommon. Cutaneous and gastrointestinal reactions and rarely leucopenia and jaundice may occur. A patient on sulfadiazine 6 g daily exhibiting a good response is reported. On the 12th day, he presented an intense abdominal pain and reduced urinary output. An ultrasonography revealed diffuse calculosis in urinary tract. Peritoneal dialysis, urinary alkalinization and rehydration were instituted with complete restoration of renal function. This case illustrates the importance of an adequate hydratation of patients receiving sulfadiazine, a simple measure in the prevention of this uncommon complication which carries a high morbidity.

[Response to the administration of corticosteroids in patients with chronic obstructive lung disease and asthma]. / Resposta à administração de corticosteróide em pacientes portadores de doença pulmonar obstrutiva crônica e asma.

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.

[Lymph node tuberculosis in adults]. / Tuberculose ganglionar em adultos.

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.

[Bronchial stenosis of tuberculous etiology: pathogenesis and treatment]. / Estenose brônquica de etiologia tuberculosa: patogenia e tratamento.

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.
