Verification of a Motion Sensor for Evaluating Physical Activity in COPD Patients.

Background: Objective evaluation of the physical activity (PA) in patients with chronic obstructive pulmonary disease (COPD) is important. We validated a triaxial accelerometer, Active Style Pro HJA-750C® (HJA), and evaluated the necessary conditions for obtaining reproducible data.

Methods: The PA measured by HJA was compared with that measured by two already validated accelerometers in 11 patients with COPD (age: 76.

Chylothorax Associated with Chronic Lymphocytic Leukemia.

An 80-year-old man who had suffered from chronic lymphocytic leukemia (CLL) and achieved complete remission was admitted to our hospital due to right pleural effusion. Thoracentesis revealed that the effusion was chyle. Lymphoscintigraphy showed an obstruction of the thoracic duct below the sternum.
