A 29-year-old Japanese man with Duchenne muscular dystrophy was placed on a mechanical ventilator support at 23 years of age and admitted to our hospital at 25 years of age. He had severe neck contracture deviated to the left side which resulted in dysphagia and microaspiration. At 29 years of age, he developed left lobar pneumonia accompanied by slight fever, back pain and a foul odor from the patient's sputum. Although the patient received broad spectrum antibiotics, pneumonia disseminated to the right lung. A week later, chest computed tomography was conducted which revealed tracheopulmonary-subcutaneous fistula, and a massive subcutaneous abscess with free air production. Drainage from the subcutaneous abscess was done through a chest tube; however, respiratory hypercapnia was not corrected and the patient died. From the culture of drained fluid, anaerobic bacteria including peptostreptococcus sp. were detected. This tracheopulmonary-subcutaneous fistula was thought to be caused by chronic microaspiration of mouth anaerobes, mechanical injury of the trachea under long term ventilator support, and decreased deep back muscle bulk with substitution of adipose tissue around the chest.

A 51-year-old man presented with back pain in 1997. He had a 30-year-history of occupational asbestos exposure. His chest CT showed bilateral pleural thickening and pleural effusion. The pleural effusion of the right thorax exhibited both elevated level of adenosine deaminase and increased numbers of lymphocytes. Antituberculous chemotherapy had no effect on the exudates. Progressive bilateral pleural thickening were found on chest CT, and pulmonary function tests showed severe restrictive ventilatory impairments since 1998. Thoracoscopic pleural biopsy was conducted in 2001 to exclude pleural malignant mesothelioma. No malignancy was found in pleural samples. After 3-year observation and excluding other causes, he was given a diagnosis of benign asbestos pleurisy. In 2005, fibrotic changes were found in both lower lung fields in chest CT. He suffered from respiratory failure with carbon dioxide retention, and died in 2006. The autopsy disclosed asbestos-related lung diseases. We suspected that diffuse pleural thickening could be a major cause of fatal respiratory impairment in this case.
