Health resource utilization and multidisciplinary impact of endoscopic ultrasonography in a tertiary referral medical center.

Background: Endoscopic ultrasound (EUS) is a resource-intensive endoscopic procedure, but may result in high downstream health resource utilization and multispecialty impact. Our aim was to examine the downstream impact of EUS by specialty and by indication.

Methods: A retrospective chart review was performed at an academic medical center for patients for whom EUS represented the first point of contact at the study institution within a 20-month period.

Increased diagnostic yield of endoscopic ultrasound-guided fine needle aspirates with flow cytometry and immunohistochemistry.

Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) is the most sensitive and specific test for establishing a tissue diagnosis for many gastrointestinal malignancies; however, cytologic morphology alone may not be definitive for subsets of tumors. Our aim was to quantify the impact of the broad application of flow cytometry (FC) and immunohistochemistry (IHC) on EUS-FNA diagnostic yield. A retrospective chart review was performed on EUS procedures at a tertiary referral, academic medical center.

Mycophenolate mofetil for maintenance of remission in steroid-dependent autoimmune pancreatitis.

Systemic corticosteroids represent the standard treatment for autoimmune pancreatitis with IgG4-associated cholangitis. For steroid-dependent disease, azathioprine has been used for maintenance of remission. Mycophenolate mofetil has been used for transplant immunosuppression and more recently for autoimmune hepatitis; however, there are no case reports to date on the use of mycophenolate mofetil in adult patients with autoimmune pancreatitis.

Titin diversity--alternative splicing gone wild.

Titin is an extremely large protein found in highest concentrations in heart and skeletal muscle. The single mammalian gene is expressed in multiple isoforms as a result of alternative splicing. Although titin isoform expression is controlled developmentally and in a tissue specific manner, the vast number of potential splicing pathways far exceeds those described in any other alternatively spliced gene.
