[A case of round atelectasis associated with spontaneous pneumothorax].

A 59-year-old female was admitted for spontaneous pneumothorax. After evacuation, the chest X-ray film showed a round mass lesion at the left hilum. Following curettage and bronchoalveolar lavage of the left B3c, the mass became smaller, suggesting the diagnosis of round atelectasis. This is the first report of round atelectasis complicated by spontaneous pneumothorax. The mechanism of this case is suggested to resemble that of round atelectasis associated with pleural effusion.

[A case of bronchial actinomycosis associated with bronchoscopically removed broncholith].

A 57-year-old woman with bronchial actinomycosis associated with broncholith is presented. She had suffered from fever and productive cough for 7 years. Her chest roentgenograms showed atelectasis of the middle lobe and calcification in the middle lobe bronchus. Bronchoscopic examination revealed a broncholith covered with pus and granulomatous tissue. The biopsy specimen revealed sulfur granules containing a partially calcified lesion, and it was diagnosed as actinomycosis. After treatment with antibiotics, the broncholith became movable, and it was removed bronchoscopically. Its shape was like a molding of the right middle lobe bronchus. We speculate that the growth of this broncholith partially resulted from chronic inflammation associated with actinomycelial infection.

[Nucleolar organizer regions, nuclear DNA content, and proliferative activity in adenocarcinoma of the lung].

The relationship between the quantity of silver-binding nucleolar organizer regions (AgNORs), nuclear DNA content, and proliferative activity was studied in 61 patients with adenocarcinoma of the lung. The proliferative activity of adenocarcinoma was estimated by tumor volume doubling time based on chest X-ray findings. There was a high, inverse correlation between the AgNORs and the tumor doubling time (p less than 0.001, r = -0.815), and the contribution rate was high value (2 = 0.664). However, the AgNORs value was an independent prognostic factor for survival time. A better 5-year survival rate was observed in patients with DNA diploidy than in DNA aneuploidy, but there was no statistical difference between the two groups. There was an inverse correlation between the DNA index and tumor doubling time (p less than 0.05, r = -0.565), but the contribution rate had a low value (r2 = 0.319). These results indicate that the AgNORs value is important in providing an estimate of the proliferative activity of adenocarcinoma.
