Advancing patient care: integrating new data.

Physicians involved in the management of patients with chronic hepatitis B infection are frequently faced with complex clinical issues concerning the diagnosis, investigation, and treatment of patients. Guidelines exist within the literature that help with decision making; however, in practice individual nuances are often encountered necessitating decisions that go beyond the current guidelines. Following presentation of the available data, a panel of expert hepatologists and gastroenterologists sought to identify and solve challenges that are faced by clinicians in the daily management of patients with chronic hepatitis B infection.

Extraesophageal symptoms: what role for the proton pump inhibitors?

The esophageal complications of gastroesophageal reflux disease (GERD) are well described and include erosive esophagitis, stricture, Barrett esophagus, and adenocarcinoma. Primary care physicians often encounter patients with "extraesophageal" manifestations of GERD in the absence of heartburn. Patients may present with symptoms involving the pulmonary system, noncardiac chest pain, and ear, nose, and throat disorders.

Hypersensitivity vasculitis with leukocytoclastic vasculitis secondary to infliximab.

Infliximab is an antibody to tumor necrosis factor (TNF) that is used in the treatment of Crohn disease and rheumatoid arthritis. This medication neutralizes TNF-alpha by binding to TNF receptors and inhibiting further induction of proinflammatory cytokines. We describe a patient with Crohn disease who developed hypersensitivity vasculitis with biopsy-proven leukocytoclastic vasculitis 9 days after her initial dose of infliximab.

Endoscopic ambulatory surgery centers in the academic medical center. We can do it too!

A freestanding ambulatory surgery center (ASC) at an academic institution is an exception rather than the rule. It is a major challenge to the concept of the traditional academic medical center. Advantages and disadvantages are discussed, as well as the detailed planning process beginning with a well executed feasibility study, the hiring of consultants, and financing of the facility.
