    Objective: The purpose of this study was to elucidate the medical check-up findings associated with smoking habit, which medical professionals, particularly physicians, should use for the promotion of quitting smoking.
    Methods: In 6,215 male and 1,627 female employees who participated in annual medical check-up, we compared the results of each test between smokers and nonsmokers.
    Results: Many results were significantly different between smokers and nonsmokers in both males and females. Among them, the hematocrit, leukocyte count, and levels of hemoglobin and triglyceride were significantly higher, the level of high-density lipoprotein cholesterol was significantly lower, and the frequencies of positive urinary occult blood and hearing loss were significantly higher in male smokers than in male nonsmokers. Furthermore, the hematocrit, leukocyte count, positive urinary occult blood, hearing loss, and levels of hemoglobin, triglyceride, and high-density lipoprotein cholesterol showed significant trends for male nonsmoker, and light, moderate, and heavy male smokers, that is, significant associations with larger numbers of cigarettes smoked per day.
    Conclusion: Not only polycythemia and low high-density lipoprotein cholesterol level but also high leukocyte count, hearing loss, positive urinary occult blood, and high triglyceride level are smoking-related abnormal findings. In the medical check-up, medical professionals should inform smokers of these data and encourage them to quit smoking.

    Objective: This study was aimed to investigate the effect of polymyxin B-immobilized fiber column (PMX) hemoperfusion treatment on the acute exacerbation of idiopathic pulmonary fibrosis (IPF).
    Patients and Methods: Six patients with a clinical diagnosis of idiopathic pulmonary fibrosis (IPF) who developed acute exacerbation were included in this study. Although five of six patients were treated with high-dose corticosteroid therapy, mechanical ventilation was necessary for all six patients due to severe respiratory failure. Blood endotoxin levels were undetectable in all patients. PMX treatment was performed on these six patients.
    Results: In four of six patients, alveolar-arterial difference of oxygen (AaDO2), serum KL-6 and lactate dehydrogenase (LDH) were improved after PMX treatment. These four patients were successfully weaned from mechanical ventilation and survived more than 30 days after the initial PMX treatment.
    Conclusion: These data suggest a potential beneficial effect of PMX treatment on acute exacerbation of IPF.

    Objective: We investigated the link between metabolic syndrome and cigarette smoking in the Japanese population.
    Methods: A total of 3,177 Japanese subjects aged 20-79 years were recruited in a cross-sectional clinical investigation study. Habits of cigarette smoking were obtained at interviews by well-trained staff. The diagnosis of metabolic syndrome was based on the new criterion in Japan.
    Results: Four hundred and forty men (35.3%) and 142 women (7.4%) were current smokers. Three hundred thirty four men (26.8%) and 69 women (3.6%) were diagnosed as metabolic syndrome. The prevalence of current smoker in subjects with metabolic syndrome was significantly higher than in subjects with non-metabolic syndrome in men with and without adjustment for age. The prevalence of metabolic syndrome in men with Brinkman index≥600 was significantly higher than that in men with Brinkman index<600.
    Conclusion: The present study indicated that cigarette smoking may be an important modifiable factor in Japanese men with metabolic syndrome.

    We encountered a case with cholangiocarcinoma of the cystic duct, which was first manifested by multiple lymph node metastases with clear cell changes resembling clear cell adenocarcinoma (CCC). Because the clear cell changes were not prominent at the primary site, clear cell transformation might have occurred preferentially at the metastatic lesion in this case. Alternatively, tumor cells with clear cell transformation, found at the primary site, might have high metastatic potential. The patient showed thromboembolism and hypercalcemia as paraneoplastic syndromes at the terminal stage as reported in patients with CCC of the ovary. Those complications might be common biological features of CCC.

    We report a 29-year-old woman with gastric cancer who developed Trousseau's syndrome, a malignancy-related thromboembolism, during chemotherapy. She was diagnosed with a mucin-producing adenocarcinoma of the stomach, and chemotherapy with S-1 and cisplatin was commenced. During treatment, she developed a sudden onset of right hemiplegia. Magnetic resonance imaging showed an acute cerebral infarction of the left cerebral hemisphere. The underlying pathophysiology is thought to be chronic disseminated intravascular coagulation due to mucin-producing adenocarcinomas. However, cisplatin-induced vascular toxicity and hypercoagulability caused by decreased plasma protein C activity, elevated plasma von-Willebrand factor levels, and hypomagnesemia has also been proposed to be associated with thrombogenicity.

    A 20-year-old man with a 15 pack-year history of cigarette smoking had a tattoo outlined on his back with blue pigment. He noticed a dry cough and shortness of breath on exertion when the pigment of other colors was added at the age of 27. He visited our hospital two years later because of severe dyspnea. He was diagnosed with desquamative interstitial pneumonia by surgical lung biopsy. Steroid therapy with cessation of smoking was partially effective, however his disease worsened again and he died three and a half years after the diagnosis because of respiratory failure.

    We describe a case of polymyositis (PM) with liver injury that occurred in a patient with rheumatoid arthritis (RA). A 74-year-old woman who had a 12-year history of RA was admitted to our hospital because of muscle weakness and liver dysfunction. CD8-positive T cell infiltration was found in the interstitium of both the liver and muscle. In addition to the administration of a large amount of prednisolone (PSL), high-dose intravenous immunoglobulin (IVIG) successfully improved myositis and hepatitis. Our case indicates the pathogenic potential of CD8-positive T cells in PM-associated liver injury.

    A 30-year-old man complained of polyarthralgia and fatigue. The clinical findings and laboratory data included myositis, polyarthritis, interstitial pneumonia, Raynaud's phenomenon, mechanic's hand, and anti PL-7 antibody (threonyl-tRNA synthetase antibody). All of these signs were consistent with antisynthetase syndrome. His chest radiograph revealed bilateral hilar lymphadenopathy. Biopsy specimens from his mediastinal lymph node and muscle showed noncaseating epithelioid cell granulomas. Lung histology revealed nonspecific interstitial pneumonia. Antisynthetase syndrome associated with sarcoidosis was diagnosed. Interstitial pneumonia in this patient responded well to high-dose corticosteroid therapy.
