Abstract
AIM Perineal wound complications and pelvic abscesses remain a major source of morbidity after total pelvic exenteration. The void created in the pelvis after these multi-visceral resections leads to fluid accumulation and translocation of bowel within the pelvic cavity, which may increase the risk of pelvic abscess, perineal fluid discharge with perineal wound dehiscence and prolonged ileus. This study describes a novel technique using degradable synthetic mesh with overlying omentum to preclude small bowel and fill the empty space after total pelvic exenteration, and aimed to investigate the rate of pelvic abscess and perineal wound-related complications in this group. METHOD Ten patients who underwent total pelvic exenteration followed by implantation of degradable synthetic mesh at a quaternary referral centre were identified and included. The mesh was moulded to the contours of the bony pelvis at the level of the pubic symphysis anteriorly and inferior to the sacral promontory posteriorly. The data on the number of postoperative perineal wound-related complications including pelvic abscesses were collected. RESULTS There was no perioperative mortality. Five patients (50%) developed postoperative complications. One patient developed an abscess inferior to the mesh that required surgical drainage and another had a pre-sacral collection that was successfully managed conservatively. Two patients developed intra-abdominal collections requiring percutaneous drainage. Median length of stay was 20 days (range 16-35). No perineal hernia or entero-perineal fistula was detected in any patient either clinically or radiologically at a median follow-up of 7 months. CONCLUSION Degradable synthetic mesh reconstruction following exenterative surgery may reduce postoperative complications related to the perineal wound.

Abstract
BACKGROUND AND PURPOSE Identification of mesial temporal sclerosis is critical in the evaluation of individuals with temporal lobe epilepsy. Our aim was to assess the performance of FDA-approved software measures of hippocampal volume to identify mesial temporal sclerosis in patients with medically refractory temporal lobe epilepsy compared with the initial clinical interpretation of a neuroradiologist. MATERIALS AND METHODS Preoperative MRIs of 75 consecutive patients who underwent a temporal resection for temporal lobe epilepsy from 2011 to 2016 were retrospectively reviewed, and 71 were analyzed using Neuroreader, a commercially available automated segmentation and volumetric analysis package. Volume measures, including hippocampal volume as a percentage of total intracranial volume and the Neuroreader Index, were calculated. Radiologic interpretations of the MR imaging and pathology from subsequent resections were classified as either mesial temporal sclerosis or other, including normal findings. These measures of hippocampal volume were evaluated by receiver operating characteristic curves on the basis of pathologic confirmation of mesial temporal sclerosis in the resected temporal lobe. Sensitivity and specificity were calculated for each method and compared by means of the McNemar test using the optimal threshold as determined by the Youden J point. RESULTS Optimized thresholds of hippocampal percentage of a structural volume relative to total intracranial volume (<0.19%) and the Neuroreader Index (≤-3.8) were selected to optimize sensitivity and specificity (89%/71% and 89%/78%, respectively) for the identification of mesial temporal sclerosis in temporal lobe epilepsy compared with the initial clinical interpretation of the neuroradiologist (50% and 87%). Automated measures of hippocampal volume predicted mesial temporal sclerosis more accurately than radiologic interpretation (McNemar test, P < .0001). CONCLUSIONS Commercially available automated segmentation and volume analysis of the hippocampus accurately identifies mesial temporal sclerosis and performs significantly better than the interpretation of the radiologist.

Abstract
A randomized double-blind study compared two methods of preventing the pain from injection of propofol, lignocaine pre-treatment followed by propofol and lignocaine added to propofol. One hundred patients received a 4 ml solution intravenously with a venous tourniquet for 1 minute, followed by propofol mixed with 2 ml of solution. Patients were divided into two treatment groups of 50 patients each: 4 ml 1% lignocaine pre-treatment followed by propofol and 2 ml saline, or 4 ml saline followed by propofol and 2 ml 2% lignocaine. Pain was assessed with a 100 mm visual analogue scale after induction and in recovery. The incidence of injection pain was 8% in the propofol mixed with lignocaine group, and 28% in the lignocaine pre-treatment group. This difference is statistically significant (P=0.017). For those patients who had pain, the mean pain score was 26.5 on induction for the propofol with lignocaine group (n=4), while the mean score was 44.4 for the pre-treatment group (n=13). The difference was not statistically significant (P=0.25). None of the propofol mixed with lignocaine group recalled pain, while 13 of the pre-treatment group did so. Lignocaine pre-treatment does not improve the immediate or the recalled comfort of patients during propofol induction when compared to lignocaine added to propofol. It is recommended that lignocaine should be added to propofol for induction rather than given before induction.

Abstract
This white paper discusses prospects for advancing hyperpolarization technology to better understand cancer metabolism, identify current obstacles to HP (hyperpolarized) 13C magnetic resonance imaging's (MRI's) widespread clinical use, and provide recommendations for overcoming them. Since the publication of the first NIH white paper on hyperpolarized 13C MRI in 2011, preclinical studies involving [1-13C]pyruvate as well a number of other 13C labeled metabolic substrates have demonstrated this technology's capacity to provide unique metabolic information. A dose-ranging study of HP [1-13C]pyruvate in patients with prostate cancer established safety and feasibility of this technique. Additional studies are ongoing in prostate, brain, breast, liver, cervical, and ovarian cancer. Technology for generating and delivering hyperpolarized agents has evolved, and new MR data acquisition sequences and improved MRI hardware have been developed. It will be important to continue investigation and development of existing and new probes in animal models. Improved polarization technology, efficient radiofrequency coils, and reliable pulse sequences are all important objectives to enable exploration of the technology in healthy control subjects and patient populations. It will be critical to determine how HP 13C MRI might fill existing needs in current clinical research and practice, and complement existing metabolic imaging modalities. Financial sponsorship and integration of academia, industry, and government efforts will be important factors in translating the technology for clinical research in oncology. This white paper is intended to provide recommendations with this goal in mind.

Abstract
BACKGROUND Pelvic exenteration (PE) is the preferred treatment available for selected patients diagnosed with locally advanced or recurrent cancer confined to the pelvis. Currently, the majority of the literature reports only on short-term survival and quality-of-life (QoL) outcomes. The aim of this prospective cohort study was to describe long-term survival and QoL outcomes following PE. METHODS This was a cohort study of consecutive patients undergoing PE from 1994 to 2016 at a major teaching hospital in Sydney, Australia. From 2008, consenting patients were also included in a prospective QoL study. Main outcomes were long-term survival and QoL assessed with SF-36® and FACT-C questionnaires. Survival was estimated using the Kaplan-Meier method. RESULTS Some 515 patients underwent PE for locally advanced or recurrent cancer. The cumulative 5- and 10-year overall survival rates were 48·6 and 37·8 per cent respectively. The survival estimates were significantly higher for patients with advanced primary rectal cancer (P = 0·045) and those in whom a clear resection margin was achieved (P < 0·001). Some 287 patients were enrolled into the QoL study. Response rates at baseline, 6 months and 5 years were 92·0, 70·0 and 33 per cent respectively. Patients had recovered to their preoperative QoL status by 6 months and, among survivors, QoL remained essentially unchanged during the 5-year follow-up. CONCLUSION Patients who underwent PE owing to advanced primary rectal cancer or achieved a clear resection margin had a greater chance of survival. Overall, QoL returned to baseline within 6 months after surgery.

Abstract
Homologous interference in vitro is defined as the ability of primary viral infection to prevent secondary homologous superinfection. Non-cytopathic bovine viral diarrhea virus (ncp BVDV) has been classified according to the exaltation of Newcastle disease phenomenon (END) as END positive (E+) and END negative (E-) strains. Simultaneous inoculation of MDBK-SY cell monolayers with BVDV/E- virus and a three log higher amount of BVDV RK13/E+ virus, leads to acquisition of the BVDV/E- feature of blocking Newcastle disease virus (NDV) infection in cells. BVDV/E- strains, particularly at a high titre and MOI ≥1.25, can exert and impose their effects in BVDV/E+ infected cells; however, if BVDV/E- MOI is reduced to MOI below 0.625, the BVDV/E+ effect can be restored leading to cytopathic effects (CPE) induction by NDV reciprocal to the titre of the BVDV RK13/E+ strain. Moreover, blocking and prevention of induced CPE by NDV or vesicular stomatitis virus (VSV) occurs even when BVDV/E- superinfects primary BVDV/E+ infected cells, indicating a defective homologous interference between BVDV/E+ and BVDV/E- strains. Taken together, BVDV/E- strains have a strong competitive potency and mediate a fast acting (i.e. within 60 min) influence against BVDV/E+ activity. This may be relevant in vivo where BVDV/E- and BVDV/E+ combinations are frequently isolated from infected individuals.
