Osteolysis in cemented titanium alloy hip prosthesis.

We evaluated 132 consecutively implanted cemented titanium alloy stems (Ti6-Al7-Nb, SLS-88) after a mean follow-up of 6.6 years (range 5-7 years). Almost 30% of the stems showed significant osteolysis, mainly in the proximal stem area.

Bernese periacetabular osteotomy.

Seventy-five symptomatic dysplastic hip joints (63 patients) were treated with the Bernese periacetabular osteotomy during a period of 44 months. The mean patients' age was 29 years (range, 13-56 years) and the female:male ratio was 3.4:1.

[Management of IIIB open tibial fractures by early osteosynthesis and local muscle flap].

From 1986 to 1994 18 patients with 19 IIIB open tibial fractures were treated following similar therapeutic management. This included early and radical primary debridement, early and wherever possible immediate internal fixation of the bone and coverage with a local muscle flap (hemisoleus or gastrocnemius). At the time of follow-up all fractures had consolidated clinically as well as radiographically.

Fatal cardiac tamponade associated with posterior spinal instrumentation. A case report.

Study Design: Case report of a fatal complication of pedicle screw instrumentation and review of the literature.

Objective: To describe the clinical and postmortem findings in a 35-year-old man who sustained a T11 burst fracture that was managed by transpedicular posterior instrumentation and who died 12 days after surgery of cardiac tamponade caused by a prick injury of the right coronary artery.

Summary Of Background Data: Posterior pedicle screw instrumentation is considered a safe and effective method for stabilizing a spinal motion segment.

Comparative investigation of drug delivery of collagen implants saturated in antibiotic solutions and a sponge containing gentamicin.

Collagen implants of various structures and a gelatine sponge were placed in five different antibiotic solutions until complete saturation occurred. The antibiotics were chosen to represent different drug classes (gentamicin sulphate, cefotaxim, fusidic acid, clindamycin, vancomycin). The collagen implants saturated with antibiotic solution and a lyophilized collagen sponge containing gentamicin sulphate were eluated in 0.

Characterization of mouse CD53: epitope mapping, cellular distribution and induction by T cell receptor engagement during repertoire selection.

The pan-leukocyte antigen CD53 is a member of the poorly understood transmembrane 4 superfamily (TM4SF) of cell membrane glycoproteins. CD53 is proposed to play a role in thymopoiesis, since rat CD53 is expressed on immature CD4-8-thymocytes and the functionally mature single-positive subset, but is largely absent from the intermediate CD4+8+ cells. We have characterized CD53 in the mouse through the production of two new monoclonal antibodies, MRC OX-79 and OX-80, which were raised against the RAW 264 cell line and screened on recombinant CD53 fusion proteins.

Serological diagnosis of Aujeszky's disease: a comparison between reactions of blood samples from sows and their offspring.

Blood sera from sows and their piglets were compared for their suitability for the serological diagnosis of Aujeszky's disease. Within a few days after parturition, blood and colostrum samples were collected from a total of 104 sows from 8 different gI-vaccinated breeding herds. Three piglets of each litter were bled simultaneously with their mother and again 3 weeks later.
