Abstract
Computed tomography (CT) scans represent the gold standard in the planning of functional endoscopic sinus surgeries (FESS). Yet, radiologists and otolaryngologists have different perspectives on these scans. In general, residents often struggle with aspects involved in both reporting and operation planning. The aim of this study was to compare the completeness of structured reports (SR) of preoperative CT images and structured operation planning (SOP) to conventional reports (CR) and conventional operation planning (COP) to potentially improve future treatment decisions on an individual level. In total, 30 preoperative CT scans obtained for surgical planning of patients scheduled for FESS were evaluated using SR and CR by radiology residents. Subsequently, otolaryngology residents performed a COP using free texts and a SOP using a specific template. All radiology reports and operation plannings were evaluated by two experienced FESS surgeons regarding their completeness for surgical planning. User satisfaction of otolaryngology residents was assessed by using visual analogue scales. Overall radiology report completeness was significantly higher using SRs regarding surgically important structures compared to CRs (84.4 vs. 22.0%, p<0.001). SOPs produced significantly higher completeness ratings (97% vs. 39.4%, p<0.001) regarding pathologies and anatomical variances. Moreover, time efficiency was not significantly impaired by implementation of SR (148 s vs. 160 s, p = 0.61) and user satisfaction was significantly higher for SOP (VAS 8.1 vs. 4.1, p<0.001). Implementation of SR and SOP results in a significantly increased completeness of radiology reports and operation planning for FESS. Consequently, the combination of both facilitates surgical planning and may decrease potential risks during FESS.

Abstract
BACKGROUND Tubular repair upon injury involves regeneration from either surviving tubular epithelial cells or from their surviving local progenitor cells; hence, compound screening with cell lines may be inadequate. Here, we demonstrate that the renal cell isolation procedure and subsequent outgrowth of tubular cells can mimic the renal injury phase and tubular cell regeneration from whichever surviving renal cells. METHODS We set up assays to systematically screen and identify mediators of tubular survival and repair. RESULTS Forty-eight hours after plating total kidney isolates from C57BL/6 mice, 69% of cells survived when prepared from 2-week-old pups, but only 4% of cells from 8-week-old mice, respectively. This poor survival was not modulated by co-incubation with any of 24 cytokines and growth factors, except for the Nrf2 agonist sulforaphane. In addition, only sulforaphane enhanced the regenerative outgrowth of tubular epithelial cells from the mixed population. Furthermore, sulforaphane enhanced wound closure upon scratching tubular epithelial cell monolayers in a dose-dependent manner. This process was associated with the induction of the tested Nrf2 target genes HO-1, NQO1 and murine-double minute 2 (MDM2). MDM2 blockade with nutlin-3a completely blocked the protective effects of sulforaphane on renal cell survival, outgrowth and wound closure. CONCLUSIONS Together, renal cell isolation is a model of acute kidney injury (AKI). Primary tubular epithelial cell outgrowth represents a model of tubular regeneration. Nrf2 activation can enhance renal cell survival and tubular repair by inducing the cell cycle regulator MDM2.

Abstract
PURPOSE The postoperative outcome and survival of patients undergoing surgery for metachronous solitary liver metastases of renal cell carcinoma were evaluated. MATERIALS AND METHODS Between 1983 and 1993, 17 patients with metachronous liver metastases of renal cell carcinoma underwent laparotomy for metastatic liver disease. All patients had undergone radical nephrectomy a mean of 3.6 years before the diagnosis of liver metastases. RESULTS Surgical resection was feasible in 13 of 17 patients with right hemihepatectomy in 9 (3 multivisceral resections), wedge resection in 4 and ex situ (mobilization and eversion out of the abdomen) resection in 1. Stage R0 resection (complete removal, negative surgical margins with no macroscopic disease left behind) was possible in 11 of 13 cases (85%). In patients with metastatic liver tissue resection the mortality rate was 31% (4 of 13) with additional significant morbidity in another 2. Mean survival of patients with nonresectable disease was 4 months, which increased to 16 months after resection. CONCLUSIONS Complete resection of metachronous liver metastases can be achieved in the majority of patients. However, significant morbidity and mortality as well as the limited prognosis even after R0 resection strongly suggest careful patient selection.
