    ABSTRACT: Background: We analysed the patient characteristics among adult asthmatics hospitalized to our hospital to clearfy the residual problems in the prevention and treatment of asthma. Methods: We identified the adult asthmatics hospitalized to our hospital during the period A: Jan 2004-Dec 2005 and the period B: Jan 2009-Dec2010 and analysed retrospectively around age, smoking history, and the use of ICS (including combination medicine) and so on. Results: The total patient numbers were A: 161 and B: 88, decreasing to almost half. The rates of the patients older than 65 years were equivalent between the 2 groups. Categorized according to age, in the group <65 years old, the rates of ICS use were A: 22.9% and B: 35.8% and the current smoking rates were A: 42.7% and B: 49.1% respectively. In the group 65≤ years old, the rates of ICS use were A: 46.2% and B: 48.6%, and the current smoking rates were A: 19.7% and B: 22.9%. Conclusion: In the group <65 years old, ICS has become more popular but smoking rate has increased among hospitalized adult asthmatics. It is estimated that smoking leads to reduce the effect of ICS and the strategy of smoking cessation will be needed to reduce acute exacerbations. In the group 65≤ years old, ICS is relatively more popular than youth and smoking rate is limited. Asthma among elder people may be refractory and more efficient strategies must be required.

    ABSTRACT: The patient was an 84-year-old woman who took a combination cold remedy, Shin-Rulu-A' for three days because of fever and cough. However, her symptoms worsened and she visited our hospital. Arterial blood gas analysis revealed severe hypoxemia and chest computed tomography showed diffuse ground glass opacities in both lungs. Analysis of bronchoalveolar lavage fluid disclosed an increased proportion of lymphocytes. The cold remedy was stopped, corticosteroids were administered, and she recovered. After positive results of lymphocyte stimulation testing to Shin-Rulu-A, a diagnosis of drug-induced pneumonitis was made. However the responsible ingredient was not established, because lymphocyte stimulation tests for each ingredient in Shin-Rulu-A were negative. To the best of our knowledge, this is the second report of Shin-Rulu-A-induced pneumonitis in Japan.

    ABSTRACT: A 47-year-old man was admitted to our hospital because of dysarthric speech and high fever. His brain magnetic resonance imaging (MRI) showed high intensity in the splenium of the corpus callosum (SCC) on diffusion-weighted and FLAIR imaging. His chest CT showed ground-glass attenuation in bilateral lung upper lobes, and consolidation in the right lower lobe. Because of his neurological findings and radiographic imaging, we started antibiotic therapy using quinolone, which is effective for Legionellosis. Later, Legionella species were identified by sputum culture. Pneumonia was relieved after antibiotic therapy and in parallel with clinical improvement, and the MRI findings also resolved. We report a patient who showed abnormal neurological findings and abnormality on brain MRI, both of which were reversible, in the setting of acute Legionnaires' disease.

    ABSTRACT: Although most patients of asthma can be controlled by inhaled corticosteroid (ICS), some patients remain uncontrolled even after the introduction of ICS treatment. In management of such difficult-to-treat asthma, systematic review including additional differential diagnosis and avoidance of exacerbating factors is very important. Here we postulate a flow sheet presenting an algorithm which intends to achieve better asthma control following ATS refractory asthma guidance. For patients with poor controlled asthma even after using ICS more than moderate dose, we used the sheet in our daily outpatient management and investigated whether we could improve the control in such patients. The sheet was constructed by an algorithm which included (1) reevaluation of inhalation technique of ICS; (2) additional differential diagnosis of COPD and other similar diseases; and (3) reevaluation of presence of exacerbating factors. In our outpatient department, seven clinicians managed 22 difficult-to-treat asthma patients using this sheet. Additional factors which might worsen asthma control could be detected in 21 patients (95.5%). Firstly, smoking was disclosed in 8 patients (36.4%). Secondly, keeping pets was identified in 7 patients (31.8%). 5 patients (22.7%) were diagnosed as COPD rather than asthma and 4 patients (18.2%) were diagnosed as having rhinosinusitis. Some improvement of asthma control was achieved in 9 patients (40.9%). Reevaluation of refractory asthma patients using our newly developed flow sheet is essential and it may facilitate understanding of management of difficult-to-treat asthma.

    ABSTRACT: A 36-year-old man was admitted to our hospital in 1994 because of fever, and abdominal CT showed multiple low-density areas in the liver. Although granulomas were found in a liver biopsy specimen, a definitive diagnosis could not be established. With complaints of oral and genital ulcerations and erythema nodosum, Behçet disease was diagnosed in 1995 and he was treated with colchicine and cyclosporin. In May 1997 he had fever, leg edema, and proteinuria, and a renal biopsy revealed secondary amyloidosis. Cavitary lesions were found on a chest X-ray for the first time, but these later disappeared spontaneously. In October 2002, nodular shadows, cavitary lesions, and a mediastinal tumor appeared on a chest X-ray film. The nodular shadows in the lung fields had transformed into cavity lesions, resulting in the disappearance of the shadows. Specimens obtained from an open lung biopsy showed necrotizing granulomas and destructive vasculitis of the lung, and aneurysm of the brachiocephalic trunk caused by destructive vasculitis. Because multiple nodular shadows with cavitary lesions in Behçet disease, as in this case, have never been reported, we think this is a rare case.

    ABSTRACT: A 70-year-old man visited our hospital with fever and general malaise. Chest CT scanning showed a large tumor shadow in the anterior mediastinum. The tumor was resected. It consisted of a portion rich in fat on the anterior mediastinal side and a solid portion on the left thoracic cavity side. Pathological examination demonstrated liposarcoma (myxoid type). The solid portion was considered to have resulted from dedifferentiation of the cystic portion. Mediastinal liposarcoma accounts for less than 1% of all mediastinal tumors. To our knowledge, there have been no previous reports of patients with myxoid-type mediastinal liposarcoma showing dedifferentiation.

    ABSTRACT: Background: A granular cell tumor is a soft tissue neoplasm which is thought to originate from Schwann cells. Most granular cell tumors are benign and malignant ones are extremely rare. Case: The patient was a 61-year-old woman complaining of pain in her right chest. A chest X-ray film showed a mass in the right apex of the pleura. A fine-needle biopsy revealed a tumor that contained large cells typically with granular cytoplasm. Clinically, we diagnosed the case as malignant granular cell tumor (MGCT), as symptoms progressed with pain worsening and the tumor becoming larger on subsequent x-ray films. Radiotherapy was not effective and the patient died of respiratory failure nine months after the original diagnosis. The autopsy showed a large tumor that could be separated from the lung. Histology revealed large granular cells and spindle cells exhibiting nuclear pleomorphism and necrosis. Immunohistochemically, S-100 protein and vimentin were detected in most tumor cells. In conclusion, we diagnosed this case as MGCT. Conclusion: On review of the literature, malignant granular cell tumors were found to be extremely rare.

    ABSTRACT: Background: Pleural lymphoma occurs exclusively in patients with long- standing pyothorax, and primary malignant lymphoma of the chest wall is rare. Case: A 84-year-old woman was hospitalized with a painful mass in the right anterior chest wall. A chest CT revealed a mass along right chest wall, which was diagnosed as malignant lymphoma (Non-Hodgkin's lymphoma, diffuse large cell, B cell type) by transcutaneous needle biopsy. We assumed this had originated from the soft tissue in the chest wall by radiographical findings. The EB virus genome, frequently detected in pyothorax-associated malignant lymphomas, was proved negative by the in situ hybridization technique, therefore further examination was warranted for etiologic factors. Conclusion: This is quite a rare case of malignant lymphoma in the chest wall without chronic empyema.
