The relationship between pleural fluid findings and the development of pleural thickening in patients with pleural tuberculosis.

The objective of the study was to determine if residual pleural thickening after treatment for pleural tuberculosis could be predicted from the pleural fluid findings at the time of the initial thoracentesis. Forty-four patients initially diagnosed as having pleural tuberculosis between January 1986 and January 1988 were separated into two groups: the 23 patients in group 1 had residual pleural disease, while the 21 patients in group 2 had no residual pleural disease after treatment for their pleural tuberculosis was completed. The clinical characteristics of the two different groups did not differ significantly, but the patients in group 1 tended to be a little sicker in that the duration of their symptoms was longer, their hemoglobin values were lower, and weight loss and cough were more frequent. There were no significant differences in the pleural fluid findings in the two different groups. The mean pleural fluid protein level was 5.40 +/- 0.58 g/dl for group 1 and 5.17 +/- 0.80 g/dl for group 2, while the mean pleural fluid glucose level was 78.6 +/- 19.5 mg/dl for group 1 and 79.5 +/- 20.1 mg/dl for group 2. The mean pleural fluid lactate dehydrogenase (LDH) level in group 1 was 593 +/- 498 IU/L, while the mean level for group 2 was 491 +/- 198 IU/L. The presence of residual pleural thickening was not related to the chemotherapeutic regimen or the performance of a therapeutic thoracentesis. From this study we conclude that approximately 50 percent of patients with pleural tuberculosis will have residual pleural thickening when their therapy is completed, but that one cannot predict which patients will have residual pleural thickening from either their clinical characteristics or their pleural fluid findings.

Respiratory failure caused by adiaspiromycosis.

Adiaspiromycosis is a rare pulmonary disorder caused by the fungus Emmonsia crescens (or Chrysosporium parvum var crescens). According to the amount of inhaled conidia, man may develop symptomatic disease. After reaching the alveoli, the adiaconidia do not multiply or disseminate, but will induce a granulomatous inflammatory reaction that may lead to fatal respiratory failure. Up to now, only five cases of disseminated pulmonary infection have been documented. This work describes the occurrence, in Brazil, of two further cases of symptomatic disease with diffuse interstitial infiltrates and severe functional impairment. Possible massive infestation during activities in closed and stuffy environments is suggested. The specific diagnosis was troublesome and could not be made by cultures, skin tests or bronchoalveolar lavage. Both patients were successfully treated, but a spontaneous resolution of the process is seriously considered.

Glucocorticoid receptor in active pulmonary sarcoidosis.

Glucorticoid receptor (GR) content of open-chest lung biopsies of 8 patients with active non treated pulmonary sarcoidosis was compared to 10 normal lungs. Results showed a higher GR level in sarcoid lungs (86.0 +/- 8.0 fMol/mg protein) than in control ones (8.2 +/- 3.1 fMol/mg protein). Our findings suggest that this increase is due to the accumulation of active cells in the sarcoid granuloma, possibly lymphocytes and or macrophages that may express cytosolic GR. The high level of this receptor in sarcoidosis may represent an indicator of the responsiveness of this disease to corticoids.

[Septic pulmonary embolism and endocarditis caused by Staphylococcus aureus in the tricuspid valve after infectious abortion. Report of 2 cases].

We report the cases of two patients with septic pulmonary embolism and respiratory failure after septic abortion. Hysterectomy was performed in both patients after unsuccessful uterine curettage and antibiotic therapy for treatment of the infection. The first patient (27 years-old) remained feverish. The blood cultures yielded Staphylococcus aureus. Tricuspid valve endocarditis was identified as the reason for persistent infection. Antibiotic treatment properly planned was administered and the patient was discharged. The second patient (23 years-old) apparently recovered after hysterectomy. Nevertheless, one month later, infection and septic pulmonary embolism recurred. The diagnosis of Staphylococcus aureus tricuspid valve endocarditis was made. Persistent infection unresponsive to medical treatment led to surgical treatment. The patient died after valve replacement. Thus the persistence or recurrence of infection and septic abortion may be due to tricuspid valve endocarditis.

Association of Sjögren's syndrome and sarcoidosis. Report of a case.

We report a case of a 57 year-old woman with Sjögren's syndrome and pulmonary complaints. After an initial evaluation, a lung biopsy was made and disclosed sarcoid lesions. This association is very rare, and the present case does not fulfill the criteria for TASS (Thyroiditis, Addison's disease, Sjögren, and Sarcoidosis). Sarcoidosis and Sjögren can coexist since both diseases may share the same immunological profile. This case report warrants further research on the overlapping of these diseases.

[Kidney failure as a complication of the treatment of pulmonary paracoccidioidomycosis].

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.

[Transport of electrolytes in the respiratory epithelium in patients with cystic fibrosis].

In the conducting airway, the epithelial electrolyte transport processes play an important role in determining the composition of the respiratory tract fluid. Apical membrane Cl- and Na+ channels control the secretion and absorption of epithelial cells. Defective regulation of these channels is a prominent characteristic of cystic fibrosis.

[Primary lung neoplasm in a patient with breast cancer: report of a case].

A pulmonary nodule in a patient with a previous or concomitant diagnosis of extrathoracic malignancy is not always a synonym of metastasis. When dealing with breast cancer this is very important since the pulmonary lesion is usually not related to the primary tumor. We present a white, 69 years old patient, submitted to mastectomy four years earlier, in which a solitary pulmonary nodule was found, and after resection, the histopathologic examination disclosed a intravascular bronchoalveolar tumor. This is a rare lesion, here represented in an unusual way.

[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.
