Magnesium 40 mg kg(-1) bolus followed by 10 mg kg(-1) h(-1) infusion leads to significant reductions in intraoperative propofol, atracurium and postoperative morphine consumption. Increasing magnesium dosage did not offer any advantages, but induced haemodynamic consequences.

Besides the ongoing ethical debate, commercial transplantation carries a high risk of unconventional complications, and despite that the patient survival rate is comparable, graft survival is worse than conventional living related transplantations at the midterm.

Endothelial dysfunction is of vital importance, as it may cause ischemia and dysfunction in various organs. Despite, this problem has been well documented in patients with end-stage renal disease (ESRD), there is not enough data considering this issue following renal transplantation. One of the potential causes of endothelial dysfunction in renal transplant recipients may be administration of calcineurin inhibitors. The aim of this study is to evaluate the effects of two different calcineurin inhibitors [cyclosporin A (CsA) and tacrolimus (FK506)] on endothelial function in renal transplant patients. Forty-four renal transplant recipients [22 on FK506 (group I) and 22 on CsA (group II)] were studied. Endothelial functions of the brachial artery were evaluated by using high resolution vascular ultrasound. Endothelium-dependent and -independent vasodilations were assessed by establishing reactive hyperemia and using sublingual nitroglycerine (NTG), respectively. Results are presented as percentage change from baseline values. Significant endothelial dysfunction was noted in renal transplant patients treated with CsA. While endothelium-dependent vasodilation was 12.1 +/- 5.1% in group I and it was 6.5 +/- 3.7% in group II (p < 0.001). The increase in brachial artery diameter after sublingual NTG was 20.1 +/- 6.3 and 12.7 +/- 5.6% in groups I and II, respectively. This indicates that the endothelium-dependent and -independent vasodilation of the patients on FK506 is better preserved than the patients on CsA therapy. Besides, blood flow volume (BFV) increase was 51.2 +/- 39.4 and 43.9 +/- 24.3%, in groups I and II, respectively, in reactive hyperemia period (p > 0.05). Post-transplant course of renal transplant recipients is complicated by endothelial dysfunction. This problem is more prominent in patients on CsA therapy, which can predispose these patients to more frequent cardiac complications.

HCV infection was associated with the development of PTDM, in addition to family history and increased age. The rate of autoantibodies against pancreatic cells was not increased in patients with HCV, which suggested that nonimmunologic mechanisms were likely to have a role in the pathogenesis of PTDM.

Rescue efforts should continue at least for 5 days after the disaster. Time under the rubble is not an adverse prognostic indicator of survival or renal dysfunction for the patients of crush syndrome, probably because only the victims with mild or moderate injuries can survive under the rubble for longer durations.
