Although the number of organ donations is extremely small in Japan, organ donation from brain dead (DBD) donors is increasing since the revised Law for Organ Transplantation was enacted on July 17, 2010. In our institution, organ donations had so far been performed from 247 donors (DCD 242, DBD 5), which is the largest number in Japan. In this study, we analyzed the status of organ donation before and after the enforcement of the revised law. ⋯ The frequency of DBD donors of all donors increased (33.3%) as compared to 9.1% before the enforcement of the revised law. Reasons for rejection of donation from donor families were mainly based on the lack of understanding of brain death. To increase organ donation, we should promote social recognition of brain death, having the Organ Donation Card, and discussion of organ donation in each family.

Facial allotransplantation represents a novel frontier in the reconstruction of complex human facial defects. To develop more refined surgical techniques and yield fine results, it is required to make a suitable animal model. The development of a model of composite facial and scalp allograft in canines is more appealing: In large animals, canine facial anatomy is the most similar to humans; its facial nerve anatomy also resembles humans'; and canines possess the most similar facial vascular anatomy to humans. These factors led to the development of a canine composite facial allograft model. ⋯ We documented that this model is well qualified in every aspect for use as a standard transplantation training model and future research work.

A left ventricular assist device (LVAD) is essential for treating patients with advanced heart failure. However, LVAD-related infection is a significant cause of mortality and morbidity, with bloodstream infection (BSI) especially associated with high mortality. We investigated the incidence of infectious complications in patients who received an LVAD and evaluated the effects of early and appropriate intervention for LVAD-related infection. ⋯ LVAD-related infections, such as drive-line and cannula infections, were common, whereas the incidence of BSI was low in our LVAD-implanted patients. Our results highlight the importance of early and appropriate intervention including antibiotics and wound care for device-related infections for reducing the incidence of potentially fatal BSI.

Fluid restriction has been used to decrease central venous pressure as a strategy of fluid management during living donor liver donation (LDLD). However, potential risks such as hemodynamic instability are also involved during the procedure. Monitoring of preload or preload responsiveness is therefore crucial during LDLD. The aim of this study was to explore the efficiency of an innovative bioreactance method that introduced the noninvasive cardiac output monitor (NICOM, Cheetah Medical, Vancouver, Wash, United States), as surrogate indicator for preload responsiveness during LDLD. ⋯ Our study has shown that SVV measured from the bioreactance technique is a poor indicator for monitoring preload responsiveness during LDLD.

In deceased-donor liver transplantation settings, post-transplantation acute renal failure with the induction of renal replacement therapy (RRT) is known to have negative effects on graft and patient survivals. However, the impact of RRT in living-donor liver transplantation (LDLT) has not been well investigated. The aim of this study was to elucidate risk factors requiring RRT and prognostic factors after its induction. ⋯ In adult LDLT patients, the induction of RRT after LDLT was a negative predictor of survival. In addition to the preoperative recipient's condition, donor factors including graft size and donor age influenced prognosis after the induction of RRT.
