The aim of this study was to establish a causal relationship between excess body weight and the onset of diabetes in a retrospective cohort study. ⋯ Overweight/obesity (high BMI) is an independent and dose-dependent risk factor for type 2 diabetes in overweight Japanese patients. Our results confirmed the usefulness of BMI as a classic parameter, and the importance of lifestyle modification and better management among people with overweight/obesity for prevention of type 2 diabetes mellitus.

Japanese chronic lymphocytic leukemia (CLL) provides a diagnostic dilemma due to the low incidence and the heterogeneity shown in its morphology and immunophenotype. We clarified the diagnostic problems in Japanese CLL through our retrospective observation. ⋯ Fluorescence in situ hybridization for CCND1/IGH, the presence of leukocytosis and lymphadenopathy at diagnosis, and the morphological evaluation using naturally air dried preparations are important clues to make a correct diagnosis of Japanese CLL.

Peripheral arterial disease (PAD) is a common clinical manifestation of the systemic atherosclerotic process, and the ankle-brachial index (ABI) is an ideal tool to diagnose PAD. Currently, there have been few long-term follow-up studies focused on the associations of the ABI with all-cause mortality and cardiovascular disease (CVD) mortality in Chinese MetS patients. The aim of this study was to evaluate the usefulness of ABI to predict the prognosis of CVD in hospitalized Chinese patients with metabolic syndrome (MetS). ⋯ An abnormal ABI value was not only a significant and independent risk factor for CVD, but also for the survival rate in Chinese MetS patients. Routine ABI evaluation could therefore be helpful for identifying high risk patients, especially MetS patients.

Case Reports
Thrombolytic therapy for cardiac arrest due to pulmonary embolism after varicose vein surgery.
Anticoagulant therapy is the mainstay in the management of venous thromboembolism. Nevertheless, the situation is entirely different in the patients with submassive or massive pulmonary embolism (PE) and cardiac arrest, and the diagnosis and therapy strategy for such conditions are lacking. ⋯ She survived after administration of 50 mg recombinant tissue plasminogen activator (rt-PA) for over half an hour, along with continued anticoagulant therapy. Unfortunately, gastrointestinal and cerebral hemorrhaging occurred during the process.

Case Reports
Pulmonary tumor embolism secondary to uterine corpus carcinosarcoma mimicking pulmonary thromboembolism.
We herein report a case of pulmonary tumor embolism caused by hematogenous metastasis that mimicked pulmonary thromboembolism in a 62-year-old Japanese woman with a history of uterine corpus carcinosarcoma. The case suggests that tumor embolism must be included in the differential diagnoses of respiratory symptoms in patients with a history of malignancy. It also illustrates the usefulness of such findings as beaded, dilated pulmonary arteries by computed tomography (CT) and high (18)F-fluorodeoxyglucose (FDG) uptake by fusion FDG positron emission tomography/CT imaging for differentiating a pulmonary tumor embolism from pulmonary thromboembolism.
