[Epidemiologic survey of pleural plaques among inhabitants of Matsubase exposed to asbestos].
A high prevalence of pleural plaques (41.5%, 148/357) was found during a mass screening for lung cancer in Matsubase town in 1988. The inhabitants of this town were carefully studied each year from 1988 to 1993. The vast majority (81.2%) of inhabitants over the age of 20 years underwent chest roentgenography at least once during this period. ⋯ The death rates and the adjusted mortality rates due to lung cancer in Matsubase were lower than in surrounding towns and lower than in Kumamoto prefecture as a whole. These results indicate that there is now no environmental contamination by asbestos fibers in Matsubase town. No cases of malignant mesothelioma have been confirmed in this town during the past 17 years.

Case Reports[Two cases of primary Sjögren's syndrome with pulmonary involvement histopathological study of open-lung biopsy specimens].
We report two cases of primary Sjögren's syndrome with pulmonary involvement, in which open lung biopsies were done. The patient in the first case was a 58-year-old woman and the patient in the second case was a 54-year-old woman. Both patients were admitted to our hospital because of dry coughing and exertional dyspnea. ⋯ Therefore, the histopathological diagnosis was cellular interstitial pneumonia with lymphoid follicles. Both patients were treated with oral corticosteroids. Symptoms were relieved and laboratory findings improved.

Case Reports[Endobronchial treatments made possible by extracorporeal lung assist in a patient in status asthmaticus refractory to mechanical ventilation].
A 19-year-old endotracheally intubated women was admitted to our hospital in severe status asthmaticus that was not relieved by inhalation of beta 2-agonists or by epinephrine, aminophylline, or corticosteroids. A chest radiography revealed pneumomediastinum and subcutaneous emphysema. Pressure-limited mechanical ventilation at a peak airway pressure of 20--30 cmH2O failed to ventilate the lungs, and caused a left pneumothorax and atelectasis. ⋯ During ECLA aerosol therapy with a large dose of a beta 2-agonist (procatherol 0.15 mg) increased the tidal volume with no adverse effects. Atelectatic areas of the lungs re-expanded, pulmonary function improved, and ECLA was stopped 86 hours after it had been started. We suggest that, although it is highly invasive, ECLA can be useful in patients with status asthmaticus refractory to mechanical ventilation, and can allow endobronchial suctioning to be done safely.

Case Reports[Invasive thymoma associated with pure red cell aplasia and lung cancer].
A 71-year-old man was admitted to our hospital with vertigo and general fatigue. Examination of his blood and bone marrow showed pure red cell aplasia. His chest X-ray film revealed an anterior mediastinal mass and a nodular shadow in the right lower lobe. ⋯ The mediastinal mass appeared to be an invasive thymoma and the nodular shadow in the right lower lobe proved to be from an adenocarcinoma. The patient was treated with radiation and steroids. Thymoma, pure red cell aplasia, and lung cancer had not recurred and he was alive and well as of 2 years after surgery.

[Suspension of ventilation during extracorporeal membrane oxygenation with veno-venous by pass in dogs].
We studied whether extracorporeal membrane oxygenation with a veno-venous bypass would allow withdrawal of mechanical ventilation. Three mongrel dogs were anesthetized with intravenous pentobarbital. A Swan-Ganz catheter was placed via the left jugular vein into the main pulmonary artery, and an extra-long total volume catheter was placed in the right femoral artery. ⋯ When the pump flow was almost the same as the previous cardiac output, the partial pressure of oxygen in the pulmonary artery, was high enough to allow ventilation to be suspended. All dogs survived. This suggests that extracorporeal membrane oxygenation with a veno-venous bypass can allow mechanical ventilation to be suspended during tracheocarinal operations such as tracheocarcinal resection.
