Abstract
Several cellular factors have been reported to be required for replication of classical swine fever virus (CSFV), a member of the genus Pestivirus within the family Flaviviridae. However, many steps of its replication cycle are still poorly understood. The low-density lipoprotein receptor (LDLR) is involved in cell entry and post-entry processes of different viruses including other members of the Flaviviridae. In this study, the relevance of LDLR in replication of CSFV and another porcine pestivirus, Bungowannah pestivirus (BuPV), was investigated by antibody-mediated blocking of LDLR and genetically engineered porcine cell lines providing altered LDLR expression levels. An LDLR-specific antibody largely blocked infection with CSFV, but had only a minor impact on BuPV. Infections of the genetically modified cells confirmed an LDLR-dependent replication of CSFV. Compared to wild type cells, lower and higher expression of LDLR resulted in a 3.5-fold decrease or increase in viral titers already 20 h post infection. Viral titers were 25-fold increased in LDLR-overexpressing cells compared to cells with reduced LDLR expression at 72 h post infection. The varying LDLR expression levels had no clear effect on permissivity to BuPV. A decoy receptor assay using recombinant soluble LDLR provided no evidence that LDLR may function as a receptor for CSFV or BuPV. Differences in their dependency on LDLR suggest that CSFV and BuPV likely use different mechanisms to interact with their host cells. Moreover, this study reveals similarities in the replication cycles of CSFV and other members of the family Flaviviridae that are dependent on LDLR.

Abstract
We report a patient with autoimmune pancreatitis and cholangitis. During a period of 3 years and despite therapy with steroids and immunmodulatory drugs such as azathioprine and mycophenolate mofetil he suffered from multiple relapse episodes including bile duct stenoses requiring endoscopic interventions. After initiation of therapy with the monoclonal CD20 antibody Rituximab, steroids could be stopped completely and the patient remains in remission. Rituximab should be considered in therapy of relapsing autoimmune pancreatitis and cholangitis.

Abstract
AIM Sentinel lymph node mapping has been used in colon cancer to improve prognosis. This study aimed to determine the accuracy of in vivo SLNM in patients with colon carcinoma undergoing surgery with curative intent. METHOD Thirty-one patients operated for colon carcinoma underwent in vivo sentinel lymph node mapping using patent blue dye. Each sentinel lymph node (SLN) was marked intraoperatively, and histological examination was performed after en bloc resection. If no metastasis was found, step sectioning with immunohistochemistry was performed. RESULTS The SLN was successfully identified in 28 (90%) of 31 patients. The false-negative rate to identify stage III disease was 66% (eight of 12), the negative predictive value was 46% (19 of 27) and the accuracy was 14% (four of 28). One patient negative on routine histopathology had micrometastasis on step sectioning of the SLN. CONCLUSION Sentinel lymph node mapping in colon carcinoma cannot accurately predict nodal status.

Abstract
BACKGROUND Paravertebral regional anaesthesia is used to treat pain after several surgical procedures. This study aimed to improve on our first published ultrasound-guided approach to the paravertebral space (PVS) and to investigate a possible discrepancy between the needle, catheter, and contrast dye position. METHODS In 10 cadavers, we conducted 26 ultrasound-guided paravertebral approaches combined with loss of resistance (LOR) and after an interim analysis performed 36 novel, pure ultrasound-guided (PUSG) paravertebral approaches. Needle-tip position was controlled by a first computed tomography (CT) scan. After placement of the catheters, the tips were assessed by a second CT and the spread of injected contrast dye was assessed by further CT scans. The part of the PVS near the intervertebral foramen was defined as the primary target to reach. RESULTS The first CT scans assessing 62 needle tips revealed that: 13 (50%) of LOR and 34 (94%) of PUSG approaches were at the target; and two (8%) LOR and no PUSG approaches were outside the PVS. With the second CT scans 60 catheter-tip positions were analysed: three (12%) of LOR and five (14%) of PUSG approaches were at the target, three (12%) of LOR and two (6%) of PUSG approaches were outside the PVS. No catheters were detected in the epidural space. In two cases, insertion of the catheter was not possible. In cases with major epidural contrast, the widest contrast dye spread was 7.7 (3.5) [mean (sd)] vertebral segments. CONCLUSIONS Our new PUSG technique has a high success rate for paravertebral needle placement. Although needles were correctly positioned, catheters were usually found distant from the needle-tip position.

Abstract
OBJECTIVES The effect of hydrostatic infiltrations for subperichondrial dissection is controversial. Classical textbooks promote it as the "key step in elevating the flaps" or consider its practicability "a mere fable". Moreover, case reports describe fatal side effects. Up to now, experimental tests are missing. DESIGN Experimental study. MATERIALS AND METHODS Three surgeons simulated subperichondrial hydrodissection with 20 mineral salt fixed human cadaver heads. One ml lidocaine 5% with 1:105 adrenaline and India ink was infiltrated. Each septum was examined histologically using serial 3 microm sections in 150 microm intervals. Tissue cleavage containing the ink deposits with minimal distance to the proposed subperichondrial zone, intravasal spread and tissue deposition were analyzed. RESULTS Every injection produced a physical dissection (n = 20). However, dissected planes were localized mostly in the supra-perichondrial connective tissue (n = 8) or within the perichondrium (n = 4). Only five cases showed the propagated correct dissection in a subperichondrial zone. Three anomalous septa were excluded from quantitative analysis. Infiltrated matter did not only accumulate within the dissection plane but also penetrated the surrounding vessels of the septal intumescentia (n = 8). CONCLUSION Hydrostatic infiltrations represent an unreliable surgical technique for dissection of an anatomical correct subperichondrial plane but can be useful for anesthesia and hemostasis, however, using high pressure and high volume infiltrations might foster serious side effects.
