Primary sclerosing cholangitis: etiopathogenesis and clinical management.
Summary of "Primary sclerosing cholangitis: etiopathogenesis and clinical management."
Primary sclerosing cholangitis (PSC) is a chronic inflammatory liver disease characterized by the destruction of medium to large-sized bile ducts and intense, concentric fibrosis. Complications from PSC include bacterial cholangitis, cirrhosis, and cholangiocarcinoma and a therapy that might alter the natural history of the disease remains lacking. Our understanding of the pathogenesis of PSC also remains rudimentary but several theories exist, suggesting roles for genetic susceptibility, abnormal innate immune responses lymphocyte trafficking, and toxic bile formation. Medical and surgical therapies, short of liver transplantation, have been disappointing. Currently, the management of PSC is aimed largely at the endoscopic treatment of dominant biliary strictures and complications of cholestasis until the disease has progressed to cirrhosis, at which time liver transplantation is indicated. Progress in our basic understanding of PSC is desperately needed in order to rationally design new therapeutic approaches to this disease.

Medical and Biotech [MESH] Definitions
Chronic inflammatory disease of the BILIARY TRACT. It is characterized by fibrosis and hardening of the intrahepatic and extrahepatic biliary ductal systems leading to bile duct strictures, CHOLESTASIS, and eventual BILIARY CIRRHOSIS.
A concept, developed in 1983 under the aegis of and supported by the National Library of Medicine under the name of Integrated Academic Information Management Systems, to provide professionals in academic health sciences centers and health sciences institutions with convenient access to an integrated and comprehensive network of knowledge. It addresses a wide cross-section of users from administrators and faculty to students and clinicians and has applications to planning, clinical and managerial decision-making, teaching, and research. It provides access to various types of clinical, management, educational, etc., databases, as well as to research and bibliographic databases. In August 1992 the name was changed from Integrated Academic Information Management Systems to Integrated Advanced Information Management Systems to reflect use beyond the academic milieu.
Management control systems for structuring health care delivery strategies around case types, as in DRGs, or specific clinical services.
The management of all procurement, distribution, and storage of equipment and supplies, as well as logistics management including laundry, processing of reusables, etc.
Participation of employees with management as a labor-management team, in decisions pertaining to the operational activities of the organization or industry.
