Thoroughly updated for its Fourth Edition, Dr. Light's text provides a focused, single-authored perspective on the pathophysiology, clinical manifestations, diagnosis, and management of pleural diseases. This edition presents new guidelines for the management of parapneumonic effusions and malignant pleural effusions--the two most difficult problems encountered in clinical practice. Coverage also includes current information on the use of markers for the diagnosis of pleural diseases, a field that has evolved significantly since the last edition. Three new chapters cover pleural diseases due to cardiovascular disorders, pleural disease following surgery, and pleural disease due to obstetric and gynecologic problems.
