BACKGROUND Pleural effusion adversely affects the pressuregenerating capacity of the diaphragm. It uncouples the lung and chest wall, which may result in diaphragmatic dysfunction. Information on the effects of effusion drainage on diaphragmatic function is limited, but several studies report relief of dyspnoea after drainage, which was attributed to improved diaphragmatic mechanics, even if th...

OBJECTIVE To examine effectiveness of standardized occupational therapy and physical therapy assessments in detecting functional changes and predicting clinical improvement in patients with suspected normal pressure hydrocephalus undergoing cerebrospinal fluid drainage. DESIGN Cohort study. PATIENTS Eighty-seven patients admitted to an inpatient neurology unit for elective cerebrospinal flu...

OBJECTIVE Published evidence indicates that surgical drainage of the pancreatic duct was more effective than endoscopic drainage for patients with chronic pancreatitis. This analysis assessed the cost-effectiveness of surgical versus endoscopic drainage in obstructive chronic pancreatitis. DESIGN This trial-based cost-utility analysis (ISRCTN04572410) was conducted from a UK National Health S...

In vivo, tissues are drained of excess fluid and macromolecules by the lymphatic vascular system. How to engineer artificial lymphatics that can provide equivalent drainage in biomaterials remains an open question. This study elucidates design principles for engineered lymphatics, by comparing the rates of removal of fluid and solute through type I collagen gels that contain lymphatic vessels o...
