Unexpected expectoration.

Induced sputum: time from expectoration to processing.

One of the limitations in the use of induced sputum to measure indices of airway inflammation is the perceived need to process the sample within 2 h. Therefore, the authors investigated whether the processing of induced sputum could be delayed. Induced sputum samples obtained from asthmatic subjects (n=30) were examined. Each sample was stored at 4 degrees C. A portion was selected and processe...

Endobronchial tuberculosis with expectoration of tracheal cartilages.

A case of endotracheal tuberculosis with expectorations of the lateral one-third of the multiple tracheal cartilages is reported. Fibreoptic bronchoscopy revealed caseous materials and loosening of the tracheal cartilages. The patient expectorated cartilaginous material several times before and after fibreoptic bronchoscopy. In spite of the loss of tracheal cartilages, tracheal lumen was mainta...

Sodium thiophene carboxylate does not facilitate expectoration.

A randomised double-blind crossover study compared the clinical effectiveness of a 21-day treatment with 600 mg per day of sodium thiophene carboxylate and placebo in 33 patients with stable chronic bronchial disease. During the seven week trial, subjective symptoms and findings were recorded, pulmonary function tests performed and sputum physical characteristics determined. Side-effects were c...

Spontaneous expectoration of primary pulmonary synovial sarcoma.

A-34-year-old Chinese man who had smoked about 20 cigarettes per day for the past 14 years presented with cough and hemoptysis that had persisted for 2 months. Chest radiography revealed mass shadow in the left lower field. A computed tomographic scan of the chest revealed the tumor in the left lower lobe, occupying left main bronchus lumen with polypoid endobronchial growth (Figure 1). Physica...
