Scientific publications are valuable markers of scientific activity for countries. We performed a bibliometric study to evaluate the number of publications written by Turkish authors. The aim of this study is to evaluate Turkey's contribution in terms of number of publications included in Science Citation Index Expanded (SCI-E) in the scientific field of liver transplantation compared with other countries. To our knowledge, this is the first bibliometric study in liver transplantation research of Turkey. ⋯ Turkey showed a significant positive trend in publications in the scientific field of liver transplantation in the last 30 years, and the rank of Turkey among other countries improved in recent decades. Currently, Turkey is one of the top 17 countries in terms of number of scientific publications listed in SCI-E. This can be considered as another indicator for Turkey's progress in the field of liver transplantation.

The experimental investigation was performed to study the effects of methylene blue (MB) on hemodynamic, biochemical, and tissue changes among rabbits undergoing liver ischemia and reperfusion (IR). Twenty-four rabbits were randomized into 5 groups: 1, SHAM, control; 2, MB infusion bolus (3 mg/kg); 3, IR, hepatic ischemia for 60 minutes followed by 120 minutes of reperfusion; 4, MB-R, undergoing ischemia that had received an MB bolus infusion (3 mg/kg) prior to reperfusion; 5, R-MB, undergoing ischemia and MB bolus infusion after hemodynamic instability caused by reperfusion. The analysis included continuous recording of vital signs. ⋯ Blood gas data revealed different patterns among the SHAM, MB, IR, MB-R, and R-MB groups, without statistical significance, except for favorable lactate results in the R-MB group (P<.01), which displayed greater survival. Biochemical tests did not show significant differences among the groups, whereas histological analysis revealed favorable appearances for the MB-R and R-MB groups. The MB effect lasted long after reperfusion, suggesting that improvement in the hemodynamic parameters was not based on liver integrity, but rather was possibly related to endothelial function.

Comparative Study
Is single-shot epidural analgesia more effective than morphine patient-controlled analgesia for donor nephrectomy?
We compared single-shot epidural analgesia (20 mL 0.125% levobupivacaine and 3 mg diamorphine) followed by regular tramadol versus morphine patient-controlled analgesia (PCA) for postoperative pain following donor nephrectomy. ⋯ In this small pilot study, SSE with 20 mL 0.125% levobupivacaine and 3 mg diamorphine, followed by regular tramadol, provided postoperative analgesia similar to morphine PCA. However, patients in the SSE group used less antiemetic medication, were independently mobile earlier, and were discharged from the hospital earlier than patients in the PCA group.

Lack of suitable donor lungs is still a major limitation of lung transplantation. Extended donor acceptance criteria combined with innovative assessment tools can be used to expand the number of suitable organs. We describe a successful transplantation of lungs retrieved from a donor who had undergone aortic root replacement 9 days before donation after cardiac death. The lungs were assessed using ex-vivo lung perfusion.

It is likely that some patients whose tumor burdens exceed the current transplant criteria have favorable tumor biology, and that these patients would have low risk of tumor recurrence after liver transplantation (LT). To assess the rate of tumor growth as selection criteria for LT in patients with hepatocellular carcinoma (HCC). ⋯ Patients with slowly growing tumor who would be currently excluded from LT because tumor burden exceeds traditional Milan and UCSF criteria may have a favorable posttransplantation outcome.
