Primary Sjogren's syndrome with anticentromere antibodies--a clinically distinct subset.

Primary Sjogren's syndrome (pSS) is a chronic autoimmune disorder of the exocrine glands. The diagnosis is largely based on keratoconjunctivitis sicca and xerostomia in the presence of anti-SS-A and/or SS-B antibodies. Anticentromere antibodies (ACA) have occasionally been reported in patients with pSS.

Clinical update on teriparatide.

Teriparatide (recombinant human parathyroid hormone ) is an anabolic agent approved for the treatment of patients at high risk for fracture. The Fracture Prevention Trial administered teriparatide to treatment-naïve patients, leading to its US Food and Drug Administration approval in 2002. Clinical trial data using antiresorptive agents administered before, during, and after any parathyroid hormone (PTH) therapy, as well as alternative PTH dosing, have provided additional insight yet raise fundamental questions about the most appropriate use of teriparatide.

Allograft transmission of hepatitis C virus infection from infected donors in cardiac transplantation.

Background: The frequency and outcome of hepatitis C virus (HCV) infection in recipients of hearts from HCV-infected donors remains poorly characterized.

Methods: Between 1991 and 1999, 10 anti-HCV-negative patients received hearts from donors who were anti-HCV and HCV RNA-positive. Each recipient was tested for anti-HCV and HCV RNA and serially evaluated for liver dysfunction.
