[Lung preserving operation for bronchogenic carcinoma--segmentectomy and bronchoplastic lobectomy].
The results of segmentectomy and bronchoplastic lobectomy for bronchogenic carcinoma were reported. Until December 1992, 920 patients underwent lung resection for primary lung cancer at our institution. Among them, 70 patients (7.6%) had segmentectomy and 149 (16.2%) had bronchoplastic lobectomy. ⋯ Five-year survival rates of those with bronchoplasty were 33.9% in total, 51.1% in those with Stage I, 29.1% in those with Stage IIIA and 39.0% in those with squamous cell carcinoma. Respiratory function was well preserved in patients with segmentectomy and bronchoplastic lobectomy. Lung-preserving operations such as segmentectomy and bronchoplastic lobectomy are meaningful as a curative procedure for primary lung cancer for selected patients.

Case Reports[Three cases of pneumothorax due to lung cancer].
Spontaneous pneumothorax due to primary lung cancers are increasingly reported as of lung cancer incidence increased. We experienced one lung cancer case with pneumothorax as a primary symptom and two who developed pneumothorax after chemotherapy, among 238 cases of primary lung cancer. In the literature, 76 cases of pneumothorax due to primary lung cancers are described. The mechanism of pneumothorax is discussed.

Case Reports[Hypersensitivity pneumonitis monitored with serum KL-6, a marker of interstitial pneumonia].
A 44-year-old man was hospitalized because of exertional dyspnea that had progressed for one month. A chest X-ray film showed bilateral small nodular and reticular shadows. The patient presented with a positive inflammatory reaction and hypoxemia. ⋯ The lactate dehydrogenose level peaked 8 days after provocation and decreased rapidly after steroid treatment. These results suggest that the serum KL-6 level provides new information regarding the clinical course and treatment of interstitial pneumonia. In addition KL-6 may be useful form monitoring disease activity, especially while tapering the dose of steroids in patients with interstitial pneumonia.

[Frequency analysis of crackles recorded with a stethoscope-equipped recorder].
Crackles were recorded with one of two systems in a total of 58 cases and compared. In one system a stethoscope was attached to a microphone; in the other system no stethoscope was used (see reference 9). Coarse crackles were recorded with the stethoscope system in 11 patients, and with the microphone-only system in 12 patients. ⋯ For both kinds of equipment, the %Type II differed significantly between coarse and fine crackles (p < 0.01). The stethoscope-transmitted sound had components that could be used to differentiate fine crackles from coarse crackles. For clinical purposes, crackles recorded with a stethoscope are as useful as those recorded with a microphone only.

Case Reports[Use of BiPAP during weaning from mechanical ventilation in a patient with chronic obstructive pulmonary disease and acute respiratory failure].
In a 65-year-old man with chronic obstructive pulmonary disease and acute respiratory failure, bi-level positive airway pressure device (BiPAP) was used as part of weaning from mechanical ventilation. As an outpatient, he had had dyspnea of grade V (Hugh-Jones) and was hypercapnic (PaCO2 of 70 torr) and hypoxemic (PaO2 of 60 torr), while he was receiving oxygen at 2 L/min via nasal cannula. Acute respiratory failure developed due to pneumonia, and mechanical ventilation was begun. ⋯ On the fifth day of mechanical ventilation, he was extubated and treatment with BiPAP was begun. He did not complain of dyspnea even though PaCO2 did not decrease, which indicates that BiPAP reduced the work of breathing. Use of BiPAP might make reintubation unnecessary when acute ventilatory failure develops soon after extubation in patients with COPD.
