Coding of tissue preparations with eurocode in Germany.

A safe look back of products requires their unique identification. Blood products are encoded in Germany with Eurocode since 1987. EU Directives 2004/23/EC und 2006/86/EC demanded unique identification and safe look back procedure also for tissues and cells.

Results of the clinical donor case and quality system case workshops of the European Association of Tissue Banks annual meeting 2009.

The European Association of Tissue Banks (EATB) Donor Case Workshop and Quality System Case workshop are forums held within the program of the EATB Annual Congress. These workshops offer an opportunity to discuss and evaluate approaches taken to challenging situations, regarding donor selection and quality issues, and strengthen the professional tissue banking and regulatory networks across Europe. This report reflects some of the discussion at the congress workshops and also subsequent correspondence between the various individuals who submitted cases for discussion.

"Eurocode International Blood Labeling System" enables unique identification of all biological products from human origin in accordance with the European Directive 2004/23/EC.

Due to their limited availability and compatibility, biological products must be exchanged between medical institutions. In addition to a number of national systems and agreements which strive to implement a unique identification and classification of blood products, the ISBT 128 was developed in 1994, followed by the Eurocode in 1998. In contrast to other coding systems, these both make use of primary identifiers as stipulated by the document ISO/IEC 15418 of the International Organization for Standardization (ISO), and thus provide a unique international code.

Allogenic versus autologous cancellous bone in lumbar segmental spondylodesis: a randomized prospective study.

The current gold standard in lumbar fusion consists of transpedicular fixation in combination with an interbody interponate of autologous bone from iliac crest. Because of the limited availability of autologous bone as well as the still relevant donor site morbidity after iliac crest grafting the need exists for alternative grafts with a comparable outcome. Forty patients with degenerative spinal disease were treated with a monosegmental spondylodesis (ventrally, 1 PEEK-cage; dorsally, a screw and rod system), and randomly placed in two groups.

Peracetic acid-ethanol treatment of allogeneic avital bone tissue transplants--a reliable sterilization method.

Objectives: Based on the European Standard EN 1040, the validation guidelines of the German Federal Institute for Drugs and Medical Devices and CPMP guidelines we tested the antimicrobial effectiveness of a peracetic acid-ethanol sterilization procedure (PES) in allogenic avital bone transplants.

Study Design: Delipidated human bone spongiosa cubes (15 x 15 x 15 mm) served as tissue. Three enveloped viruses (human immunodeficiency virus type 2, pseudorabies virus, bovine virus diarrhoea virus) and three non-enveloped viruses (hepatitis A virus, poliovirus, porcine parvovirus) were used.
