The authors report a case of spontaneous bilateral diaphyseal femoral fractures believed to be caused by oversuppression of bone remodeling as a result of long-term, high-dose treatment with bisphosphonate. The patient reported pain in both thighs before the fractures. Typical pathologic changes appeared on both femoral radiograph and bone scan before the fractures. Several hours after admission to the emergency department of the authors' institution, the patient underwent closed re-duction and internal fixation with intramedullary nails for the bilateral femoral diaphyseal fractures. Treatment with zoledronic acid was immediately discontinued. In recent years, low-energy femoral diaphyseal fractures in patients undergoing long-term bisphosphonate treatment have been reported. It is believed that the prolonged treatment causes long-term suppression of bone remodeling and accumulation of microdamage. It is important to observe patients who are undergoing bisphosphonate treatment carefully. In this case study, the authors report the patient's unique medical history. Source

End-stage liver disease is a life threatening health problem to millions of people worldwide. Orthotopic liver transplantation is the only therapy for the definitive cure at the present time. However, persistent shortage in donor organs limits the opportunity for patients to receive this treatment. Liver tissue engineering aims to overcome this restriction by generating functional tissue constructs for treatment of individuals with the end-stage liver disease. Recently, a new strategy has emerged using the natural organ scaffold as a vehicle for liver tissue engineering. This involves preparation of decellularized scaffold containing the circulatory framework of the natural organ system. Currently, surgical performance of liver scaffold transplantation with end-to-side anastomosis of major vessels in small experimental animals, particularly in mice (mLBST), remains technically challenging. Here, we describe surgical techniques of mLBST that can be used for evaluation of engineered liver grafts in recipients. © 2015, E-Century Publishing Corporation. All rights reserved. Source
