Case Reports
Lung adenocarcinoma in lymphocytic interstitial pneumonitis associated with primary Sjögren's syndrome.
We experienced a rare case of lung adenocarcinoma associated with lymphocytic interstitial pneumonitis caused by primary Sjögren's syndrome. A 78-year-old woman was referred to our hospital because of progressive sicca syndrome and nodular opacities in the right lower lobe on chest radiograph. This patient was diagnosed as primary Sjögren's syndrome by a labial gland biopsy and classical clinical features including xerophthalmia, xerostomia and immunoserological findings. ⋯ There was no evidence of malignant lymphoma in the lymph nodes or resected lung tissue. Pulmonary involvement of Sjögren's syndrome is now regarded both clinically and histopathologically as a wide spectrum of lymphoproliferative disorders ranging from benign to malignant. However, lung cancer associated with primary Sjögren's syndrome, as in our case, has apparently not been reported previously.

Randomized Controlled Trial Clinical Trial
Effect of early application of biphasic positive airway pressure on the outcome of extubation in ventilator weaning.
Extubation failure is significantly associated with increased morbidity and mortality in mechanically ventilated patients. In respiratory distress after extubation, non-invasive positive pressure ventilation (NIPPV) has been suggested to avoid the complications of invasive mechanical ventilation. The purpose of this study was to evaluate the effect of early application of NIPPV on extubation outcome. ⋯ Patients with excessive bronchial secretions and intolerance to the equipment are poor candidates for NIPPV. We conclude that early application of BIPAP support did not predict a favourable extubation outcome. Our experience did not support the indiscriminate use of NIPPV to facilitate ventilator weaning.
