Late onset hyperplastic callus formation in osteogenesis imperfecta type V simulating osteosarcoma-A case report.

Introduction: We report a case of late onset hyperplastic callus formation (HPC) in the right femur in type V osteogenesis imperfecta (OI) mimicking the occurrence of a malignant osteosarcoma.

Presentation Of Case: A 27-year-old female patient consulted us due to swelling in her right femur over 2-3 months without trauma. X-rays looked like an osteosarcoma, blood tests showed increased bone metabolism.

Regular, in-situ, team-based training in trauma resuscitation with video debriefing enhances confidence and clinical efficiency.

Background: To assess the clinical impact of a regular, multidisciplinary, video debriefed training intervention for trauma team members on real trauma resuscitations. In addition, attending personnel evaluated the training program via questionnaire.

Methods: The training intervention is a regular (monthly), video debriefed, team-based trauma simulation.

Comparison of straight and Venaflo-type cuffed arteriovenous ePTFE grafts in an animal study.

Background: The long-term prognosis of arteriovenous (AV) polytetrafluoroethylene (PTFE) hemodialysis grafts is dissatisfying. Responsible for the poor outcome is a stenosis of the venous anastomosis. This originates from both pseudointimal (PI) and neointimal hyperplasia (IH) development.
