Acetabular reconstruction with the Burch-Schneider ring: an EBRA analysis of 40 cup revisions.

Background: Reconstruction of the bone stock and fixation of the implant remain challenging problems in revision surgery. In this retrospective study, we wanted to gain information on initial stability and wear after revision with the Burch-Schneider ring.

Patients And Methods: Between 1994 and 1998, we performed 70 reconstructions of the acetabulum with a Burch-Schneider ring in revision arthroplasty.

Identifying, evaluating and quantifying adverse drug reactions in children: opportunities and obstacles for the manufacturer.

The monitoring of the safety of its marketed products is a recognized responsibility of the pharmaceutical manufacturer. He has the advantage to concentrate efforts on a relatively small number of compounds and to include a large number of sources and methods. Drug monitoring is especially crucial for the vulnerable groups of patients (children, pregnant women, mentally incompetent and elderly) for whom adequate controlled clinical trials are often lacking with the notable exception of pediatric oncology and vaccinations.
