Spontaneous regression of multiple emphysematous bullae.
The etiology of emphysematous bullae is not well known; thus, the management of bullous lung disease is often difficult because of concomitant underlying emphysema and coexisting cardiac conditions. The present paper reports a case in which near complete resolution of multiple emphysematous bullae in the right lung occurred spontaneously. This case is of interest, not only because of the rarity with which spontaneous regression of multiple emphysematous bullae has been reported in the literature, but also because of the accompanying dramatic improvements in radiological results and pulmonary function of the patients.

Clinical evaluation of CYFRA 21-1 in malignant pleural fluids.
The diagnostic value of the novel tumor marker CYFRA 21-1 in malignant pleural fluid was assessed in comparison to carcinoembryonic antigen (CEA). CYFRA 21-1 and CEA were measured in pleural fluid obtained from patients with 108 malignant and benign diseases. The levels of pleural fluid CYFRA 21-1 in malignant diseases (median: 84.5 ng/ml) were statistically higher than those in benign diseases (median: 13.9 ng/ml; p < 0.01). The CYFRA 21-1 test was able to discriminate significantly between squamous cell lung cancer and pneumonia (p < 0.01), while pleural fluid CEA levels could not. Receiver operating characteristic (ROC) curve analysis showed that the CYFRA 21-1 test has an advantage over CEA because of its higher specificity. These results indicate that measurement of CYFRA 21-1 in pleural fluid is a new tool, in addition to cytologic examination, to discriminate between malignant and benign diseases.
