Abstract
BACKGROUND Minimally invasive techniques for Achilles tendon repair are increasing due to reports of similar rerupture rates using open and percutaneous techniques with fewer wound complications and quicker recovery with percutaneous methods. The goal of this study was to investigate quantitatively the relationship and risk of injury to the sural nerve during Achilles tendon repair when using the Percutaneous Achilles Repair System (PARS) (Arthrex®, Naples, FL), by recording the distance between the passed needles and the sural nerve as well identifying any direct violation of the nerve with needle passage or nerve entrapment within the suture after the jig was removed. The hypothesis of the study is that the PARS technique can be performed safely and without significant risk of injury to the sural nerve. METHODS A total of five needles were placed through the PARS jig in each of 10 lower extremity cadaveric specimens using the proximal portion after simulation of a midsubstance Achilles tendon rupture. Careful dissection was performed to measure the distance of the sural nerve in relation to the passed needles. The sutures were then pulled out through the incision as the jig was removed from the proximal portion of the tendon and observation of the suture in relation to the tendon was documented. RESULTS Of the 10 cadaveric specimens, none had violation of the sural nerve. Zero of the 50 (0%) needles directly punctured the sural nerve. In addition, upon retraction of the jig, all sutures were noted to reside within the tendon sheath with no entrapment of the sural nerve noted. CONCLUSION This study demonstrated the variable course of the sural nerve and identifies the potential risk for sural nerve injury when using the PARS for Achilles tendon repair. However, this study provides additional evidence of safety from an anatomic standpoint that explains the outcomes demonstrated in the clinical trials. With this information the authors believe surgeons should feel comfortable they can replicate those outcomes while minimizing risk of sural nerve injury when the technique is used correctly.

Abstract
Purpose To assess the prevalence of intra-articular findings with ankle arthroscopy in patients undergoing operative fixation for ankle fractures. Methods This is a retrospective review of ankle fractures that were treated with arthroscopy and open reduction and internal fixation by a single surgeon. Between August 2016 and July 2018, operative reports, office notes, and images were reviewed to identify intra-articular pathology and fracture type. An analysis was performed with regard to fracture type, presence and location of osteochondral lesions, loose-bodies, syndesmotic injury, and deltoid injury. Results Fifty-seven ankle fractures were identified that met inclusion criteria. In total, 84.2% of the fractures had intra-articular pathology, most commonly a syndesmotic injury followed by presence of intra-articular loose bodies and osteochondral defects. Conclusions In our study, use of arthroscopy before open ankle fracture fixation identified intra-articular pathology in 84.2% of subjects. The most common pathology was syndesmotic injury. The addition of an arthroscopic assessment in patients with operatively treated ankle fractures may help improve treatment provided to patients during ankle fracture surgery. Level of Evidence Level 4 Therapeutic Case Series.

Abstract
Aims To explore the integration and delivery of oncology led referrals to palliative care (PC) by examining physician attitudes and referral practices. Methods An online survey was circulated to oncologists and PC physicians in Ireland. Results The study (N = 100) comprised sixty-nine oncologists (69%) and thirty-one PC physicians (31%). Ninety-two(92%) believe patients with advanced cancer should receive concurrent treatment, however only 53% of oncologists(N = 37) routinely refer. Regarding end-of-life (EOL) care: 81% of oncologists (N = 55) are directly involved in its administration, despite 84% (N = 53) agreeing patients benefit when PC specialists coordinate EOL care. Conclusion The gulf between positive attitudes and limited implementation suggests the need for interdisciplinary changes to facilitate integration of PC in clinical practice in Ireland.

Abstract
BACKGROUND Vocabulary deficits are the most frequently documented communication difficulty following childhood acquired brain injury (ABI). Given the adverse consequences of limited vocabulary on academic success, it is critical to identify the presence and nature of vocabulary impairments to provide effective intervention for children with ABI. METHOD Eleven children (7;6-11;11) with moderate/severe ABI (>12 months post-injury) and individually matched typically developing (TD) controls completed an Australian adaptation of a vocabulary assessment based on a three-tiered framework: tier 1 (basic words), tier 2 (high-frequency, cross-curricular words), and tier 3 (curriculum-based words). Overall scores and tiered accuracy were compared at individual and group level. Type and frequency of expressive naming errors were also coded. RESULTS In this pilot study, children with ABI demonstrated poorer overall scores than TD children. Equivalent accuracy was noted for tier 1 words and tier 2 receptive words. However, significantly poorer accuracy was noted in the ABI group for tier 2 expressive words and all tier 3 words. The majority of naming errors were semantic across both groups although TD participants showed a wider distribution of error types. CONCLUSIONS Findings support the use of tier 2 and 3 vocabulary as intervention targets in this population within education contexts and speech pathology settings.

Abstract
BACKGROUND Initial management of symptomatic accessory navicular in pediatric patients is nonoperative. However, efficacy of nonoperative treatment has not been studied or established. If nonoperative treatment is frequently unsuccessful or does not give lasting pain relief, surgery could be offered as first line treatment. This study retrospectively reviewed outcomes of pediatric patients treated nonoperatively for symptomatic accessory naviculae in an effort to provide clinicians success rates for their discussion of treatment options with patients and their families. METHODS A retrospective analysis of pediatric patients diagnosed and treated nonoperatively for a symptomatic accessory navicular bone at Cincinnati Children's Hospital Medical Center between dates August 1st, 2006 and August 24th, 2016 was performed. Outcome measures consisted of complete pain relief, partial relief without operative intervention, or need for operative intervention. Radiographic imaging for each patient was also used to identify the type of accessory navicular and presence of concurrent pes planus. RESULTS A total of 169 patients were included, with 226 symptomatic accessory naviculae. Average age at diagnosis was 11.8 years, with majority females (78%). Type 2 accessory naviculae were most frequent (72.7%), with Type 1 and Type 3 in 9.7% and 17.4%, respectively. Average number of nonoperative trials was 2.1, with 28% experiencing complete pain relief, 30% requiring surgical intervention, and 41% that experienced partial pain relief and did not require surgical intervention, and were recommended as needed (PRN) follow-up based on clinical improvement. Of those that achieved complete pain relief, the average length of non-operative treatment was 8.0 months. CONCLUSIONS The results of this study can be used by clinicians to frame discussions surrounding treatment options for symptomatic accessory navicular bones with both patients and their families.Level of Evidence: III.

Abstract
Category: Midfoot/Forefoot Introduction/Purpose: Initial management of symptomatic accessory naviculae in pediatric patients is nonoperative. Common first line treatments include casting, shoe wear modification, limiting strenuous activities, and nonsteroidal anti-inflammatories. When nonoperative treatments fail to mitigate symptoms, surgery is indicated. Surgical treatment of symptomatic accessory navicular bones has been extensively studied. However, the efficacy of nonoperative treatment for alleviating pain or preventing surgery in effected patients has not been established. We believe that nonoperative treatment is frequently unsuccessful or does not give lasting pain relief, thus questioning whether surgery could be offered as first line treatment. Our study retrospectively reviews outcomes of adolescents treated non-operatively for symptomatic accessory naviculae in an effort to provide clinicians success rates for their discussion of treatment options with patients and their families. Methods: This is an IRB approved, retrospective study of adolescent patients diagnosed and treated non-operatively for symptomatic accessory navicular bones at Cincinnati Children’s Hospital Medical Center between the dates 8/1/2006 and 8/24/2016. Medical records were used to identify demographic information, type, duration, and total trials of conservative treatment, additional foot comorbidities, response to conservative management, and surgery if non-operative management failed. Included patients were under 18 years of age with medial sided foot pain, radiographic evidence of an accessory navicular, and had undergone at least 1 course of non-operative treatment. Patients with previously operated on accessory naviculars or other diagnosed painful foot conditions were excluded. Outcome measures consisted of pain relief, no surgical intervention, or need for surgical intervention. Available radiographic imaging for each patient was also used to identify type of accessory navicular and determine pes planus incidence. Statistical analysis using measures of central tendency was then performed. Results: 169 patients were included, with 226 symptomatic accessory naviculae. Average age at diagnosis was 11.8 years, with 78.2% females, and 22% males. 53 (32%) were left symptomatic accessory naviculae, 56 (33%) right, and 60 (36%) bilateral. Type II accessory naviculae were most frequent (72.7%), with Type I and Type III in 9.7% and 17.4%, respectively. 56% were chronic in nature, with 31% due to acute injury. Average number of non-operative trials was 2.08, with 28% experiencing complete pain relief, 30% requiring surgical intervention, and 41% that did not require surgical intervention, but were without documented pain relief. Of those that achieved complete pain relief, average length of non-operative treatment was 8.03 months. Conclusion: Results of this study can be used by clinicians to frame discussions surrounding treatment options for symptomatic accessory navicular bones with both patients and their families. Further research is warranted to determine the necessary duration and type of non-operative treatment, among those most commonly used, that is most successful in providing pain relief.

Category: Trauma Introduction/Purpose: The purpose of this study is to evaluate risk factors and complications associated with surgical treatment of calcaneus fractures using a sinus tarsi approach in a consecutive series of 164 displaced intra articular calcaneus fractures treated with a sinus tarsi approach. Methods: 150 patients with a total of 164 displaced intra articular calcaneus fractures were treated by a single surgeon using a sinus tarsi approach. Age, nicotine use, diabetes, steroid use, time from injury to surgery were all recorded. Time of suture removal, post operative antibiotics, local wound care and need for secondary surgery for wound problems were recorded. Results: average age was 49.5 years old. follow up averaged 309 days. 60 (39.2%) used nicotine, 14 (8.54%) were diabetics with 3 insulin dependent, 6 used oral steroids or DMARDs, eight fractures (4.88%) were open fractures. Average time from injury to surgery was 10.63 days. Sutures were removed at an average of 16.25 days. 7 patients developed incisional complications. 6 were treated successfully with antibiotics and local wound care. 1 patient require secondary surgery for wound complications. There was no difference in patients treated less then 14 days or more then 14 days from injury. there was no difference in complications in smokers vs. non smokers or diabetics vs. non diabetics. Conclusion: The sinus tarsi approach is a safe surgical approach with an acceptable complication rate for fixation of displaced intra articular calcaneus fractures.

Abstract
UNLABELLED Two Gram-negative Enterobacteriaceae, Gibbsiella quercinecans and Brenneria goodwinii, are frequently isolated from oak suffering from Acute Oak Decline. These two species are difficult to identify based on colony morphology, carbohydrate utilization or 16S rRNA gene sequence, and identification using gyrB gene sequencing is time-consuming and laborious. A rapid identification technique, based on high-resolution melt analysis of the atpD gene, was designed to efficiently process numerous isolates from an increasing number of affected woodlands and parks. Principal component analysis of the resulting melt curves from strains of G. quercinecans, B. goodwinii and their close phylogenetic relatives allowed differentiation into distinct clusters based on species or subspecies identity. SIGNIFICANCE AND IMPACT OF THE STUDY Acute Oak Decline is an increasing threat to Britain's native oak population. Two novel bacterial species both belonging to the family Enterobacteriaceae, Gibbsiella quercinecans and Brenneria goodwinii, are thought to play an important role in symptom development. Here, we describe a rapid identification technique using high-resolution melt analysis of the atpD gene able to assign isolates to either G. quercinecans or B. goodwinii in a single assay, greatly reducing the time taken to identify if either or both of these species are present in symptomatic oak.

Abstract
Art therapy has a long history in mental health care but requires an enhanced evidence based in order to better identify its precise role in contemporary services. This paper describes an evaluation of an art therapy programme in an acute adult psychiatry admission unit in Ireland. A mixed method research design was used. Quantitative data were collected through a survey of 35 staff members and 11 service-users. Qualitative data included free-text comments collected in the survey and individual feedback from service-users. Both methods aimed to assess the role of art therapy as part of a multidisciplinary mental health service. Thematic content analysis was employed to analyse qualitative data. Staff demonstrated overwhelming support for art therapy as one element within multidisciplinary services available to patients in the acute psychiatry setting, qualitative feedback associated art therapy with improvements in quality of life and individual support, and emphasised its role as a nonverbal intervention, especially useful for those who find talking therapy difficult. Creative self-expression is valued by staff and service-users as part of the recovery process. Recommendations arising from the research include continuing the art therapy service, expanding it to include rehabilitation patients, provision of information and education sessions to staff and further research to identify other potential long-term effects. The low response of staff and small sample in this study, however, must be noted as limitations to these findings.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
Salmonella carriage in pigs is a significant food safety issue. Dietary supplementation with organic acids has previously been shown to reduce shedding and transmission of Salmonella. Therefore, this study aimed to examine the effect of three commercially available organic acid-based products on Salmonella levels in grower pigs, using a model of experimental infection that closely mimics natural exposure to the organism. Seven week old trial pigs (n=40) with a mean weight of 14.7kg were placed in one of four pens with 10 pigs/pen. Pens had previously been contaminated with Salmonella Typhimurium 4,[5],12;i;- via seeder pigs. Trial pigs received one of four diets for 28days: 1, control diet; 2, sodium butyrate supplemented diet; 3, benzoic acid supplemented diet and 4, formic-citric acid supplemented diet. A further 10 pigs were placed in a Salmonella-free pen receiving the control diet. Pigs were weighed and blood sampled on days 0 and 28. Faeces was collected on day 0, 2, 3, 5, 7, 14, 21 and 28 and examined for Salmonella. On day 28, 5 pigs/group were euthanised and ileocaecal lymph nodes (ILN) and caecal contents sampled for culture. The remaining 5 pigs/pen were then fed the control diet and faeces were collected on days 35 and 42. On day 42 pigs were euthanised and ILN and caecal contents tested for Salmonella levels. The trial was repeated once. Within the first two days of exposure to the contaminated environment, 96% (77/80) of pigs became infected. Most pigs shed Salmonella at levels of between 100-103 CFU/g faeces for at least 7days post-exposure. A significant reduction in Salmonella faecal concentration was observed after supplementation with sodium butyrate (p=0.001) and a formic citric acid blend (p<0.0001). Average daily weight gain (ADWG) was significantly increased in all groups fed the supplemented feed when compared to the positive control group. The use of sodium butyrate or a blend of formic and citric acid in feed could be considered a cost-effective control measure to reduce Salmonella faecal shedding and improve ADWG in Salmonella infected herds.

Abstract
BACKGROUND EGFR mutated lung cancer represents a subgroup with distinct clinical presentations, prognosis, and management requirements. We investigated the survival, prognostic factors, and real-world treatment of NSCLC patients with EGFR mutation in clinical practice. METHODS A retrospective review of all specimens sent for EGFR analysis from December 2009 to September 2015 was performed. Patient demographics, specimen type, EGFR mutation status/type, stage at diagnosis, treatment, response rate, and survival data were recorded. RESULTS 27/334 (8%) patient specimens sent for EGFR testing tested positive for a sensitising EGFR mutation. The median age was 65 years (40-85 years). Exon 19 deletion represented the most commonly detected alteration, accounting for 39% (n = 11). First-line treatment for those with Exon 18, 19, or 21 alterations (n = 24) was with an EGFR tyrosine kinase inhibitor (TKI) in 79% (n = 19). Objective response rate among these patients was 74% and median duration of response was 13 months (range 7-35 months). CONCLUSION The incidence of EGFR mutation in our cohort of NSCLC is 9% which is consistent with mutation incidence reported in other countries. The rate of EGFR mutation in our population is slightly below that reported internationally, but treatment outcomes are consistent with published data. Real-world patient data have important contributions to make with regard to quality measurement, incorporating patient experience into guidelines and identifying safety signals.

Abstract
Background Breast carcinoma metastasis to the gastrointestinal tract is rare and more frequently associated with lobular than ductal carcinoma (Borst and Ingold, Surg 114(4):637–641 [1]). The purpose of this article is to present a case based review of a unique gastrointestinal metastasis and literature review. Methods A 46 year old lady with metastatic invasive ductal breast cancer was admitted to A&E with sudden onset of epigastric and left shoulder pain. She completed the first cycle of capecitabine/vinorelbine 1 week previously. Clinical examination revealed a tender epigastrium with rigidity in the upper abdomen. Free air under the diaphragm and a positive Rigler’s sign was radiologically identified. A laparoscopy demonstrated a fibrinous exudate in the left upper quadrant consistent with a walled off lesser curvature gastric perforation. A subsequent oesophagogastroduodenoscopy (OGD) demonstrated a healed gastric ulcer of benign appearance; however the pathology confirmed metastatic breast carcinoma. Results Literature review confirmed no previously reported cases of vinorelbine induced gastric perforation. Four cases of metastatic breast cancer with gastric metastasis presenting with perforation were identified; three of these cases (Fra et al., Presse Med 25(26):1215 (1996) [2], Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91–92 (2004) [3], Ghosn et al., Bull Cancer 78(11):1071–1073 (1991) [4]), were in the French medical literature, including one male patient (Fra et al., Presse Med 25(26):1215 (1996) [2]) and at least one ductal breast carcinoma (Solis-Caxaj et al., Gastroenterol Clin Biol 28(1):91–92 (2004) [3]). The fourth case (van Geel et al., Ned Tijdschr Geneeskd 144(37):1761–1763 (2000) [5]), was in the Dutch medical literature and a lobular breast carcinoma. Conclusion This case represents a rare complication of breast cancer chemotherapy, the subsequent significant benefit the patient received from treatment is consistent with the chemosensitivity to therapy that also resulted in gastric perforation. Five years after gastric perforation she resumed palliative chemotherapy after progression on sequential hormonal therapies.

Abstract
Traditional DNA-based typing focuses primarily on interrogating the exons of human leukocyte antigen (HLA) genes that form the antigen recognition domain (ARD). The relevance of mismatching donor and recipient for HLA variation outside the ARD on hematopoietic stem cell transplantation (HSCT) outcomes is unknown. This study was designed to evaluate the frequency of variation outside the ARD in 10 of 10 (HLA-A, -B, -C, -DRB1, -DQB1) matched unrelated donor transplant pairs (n = 360). Next-generation DNA sequencing was used to characterize both HLA exons and introns for HLA-A, -B, -C alleles; exons 2, 3 and the intervening intron for HLA-DRB1 and exons only for HLA-DQA1 and -DQB1. Over 97% of alleles at each locus were matched for their nucleotide sequence outside of the ARD exons. Of the 4320 allele comparisons overall, only 17 allele pairs were mismatched for non-ARD exons, 41 for noncoding regions and 9 for ARD exons. The observed variation between donor and recipient usually involved a single nucleotide difference (88% of mismatches); 88% of the non-ARD exon variants impacted the amino acid sequence. The impact of amino acid sequence variation caused by substitutions in exons outside ARD regions in D-R pairs will be difficult to assess in HSCT outcome studies because these mismatches do not occur very frequently.

Abstract
Using the Center for International Blood and Marrow Transplant Research (CIBMTR) registry, we analyzed 1,404 UCBT patients [single (< 18 years) = 810, double (≥ 18 years) = 594] with acute leukemia to define the incidence of acute and chronic graft-vs.-host disease (GVHD), analyze clinical risk factors and investigate outcomes. After single UCBT, 100-day incidence of grades II–IV aGVHD was 39% (95% CI, 36–43%), grades III–IV aGVHD was 18% (95% CI, 15–20%), and 1-year cGVHD was 27% (95% CI, 24–30%). After double UCBT, 100-day incidence of grades II–IV aGVHD was 45% (95% CI, 41%–49%), grades III–IV aGVHD was 22% (95% CI, 19–26%), and 1-year cGVHD was 26% (95% CI, 22–29%). For single UCBT, multivariate analysis showed that absence of anti-thymocyte globulin (ATG) was associated with aGVHD, whereas prior aGVHD was associated with cGVHD. For double UCBT, absence of ATG and myeloablative conditioning were associated with aGVHD, while prior aGVHD predicted for cGVHD. Grades III–IV aGVHD led to worse survival whereas cGVHD had no significant effect on disease-free or overall survival. GVHD is prevalent after UCBT with severe aGVHD leading to higher mortality. Future research in UCBT should prioritize prevention of GVHD.

Abstract
BACKGROUND We describe the preliminary clinical results of a patellar stabilization technique to treat bidirectional patellar subluxation (BPS). METHODS Patients: six patients (one male, five females; mean age 30.2years) underwent this procedure with a minimum of 24months follow-up. Patients were assessed for clinical instability, patellar complications, and need for revision surgery. Patient functional outcomes were evaluated using the criteria of Crosby and Insall and the Kujala Anterior Knee Pain Scale at the time of final follow-up. Patient satisfaction was assessed using a subjective questionnaire. OPERATIVE TECHNIQUE A semitendinosus tendon autograft is coursed through a transverse tunnel in the distal quadriceps tendon. The medial and lateral aspects of the graft are passed from the quadriceps tendon within subfascial tunnels to the MPFL attachment site and lateral epicondyle, respectively. The graft is fixed in 60° of knee flexion with suture anchors. RESULTS Surgery for recurrent instability was performed in one case. There were no cases of infection, quadriceps tendon rupture, or patella fracture. At average follow-up of 29.2months (range, 24 to 38months), outcomes were good to excellent in 4/6 of cases. Kujala scores improved significantly from 33.3 (range, three to 58) preoperatively to 70.8 (range, 39 to 96) postoperatively (p<0.05). 5/6 patients reported being satisfied to completely satisfied with their result. CONCLUSION Patients undergoing bidirectional patellar stabilization with a single tendon graft showed improved postoperative functional scores. The technique is successful in reducing pain and restoring bidirectional patellar stability at 2-years follow-up. LEVEL OF EVIDENCE IV, retrospective case series.

Using a mixed method approach, we surveyed 125 patients and 361 medical practitioners (doctors and medical students) views of the doctor-patient relationship. We qualitatively assessed patients' views of what constituted a good doctor and qualitatively measured empathy using a validated scale in medical practitioners. Patients desire a doctor that is both clinically proficient 66 (55%) and caring 32 (27%). Doctors who have a personal experience of illness have a statistically higher empathy score. These doctors may be well placed to help develop and foster empathy in our profession.

Abstract
The first gapA and dnaK phylogenetic analysis of Mollicute species. Analysis includes a wide range of haemoplasmas species. Analysis supports that haemoplasmas reside within a single clade. Evidence of phylogenetic distance between the haemoplasmas and Mycoplasma species.
Nine species of uncultivable haemoplasmas and several Mycoplasma species were examined by partial sequencing of two protein-encoding housekeeping genes. Partial glyceraldehyde-3-phosphate dehydrogenase (gapA) and heat shock protein 70 (dnaK) gene sequences were determined for these Mollicute species; in total nine gapA sequences and ten dnaK sequences were obtained. Phylogenetic analyses of these sequences, along with those of a broad selection of Mollicute species downloaded from GenBank, for the individual genes, and for the gapA and dnaK concatenated data set, revealed a clear separation of the haemoplasmas from other species within the Mycoplasma genus; indeed the haemoplasmas resided within a single clade which was phylogenetically detached from the pneumoniae group of Mycoplasmas. This is the first report to examine the use of gapA and dnaK, as well as a concatenated data set, for phylogenetic analysis of the haemoplasmas and other Mollicute species. These results demonstrate a distinct phylogenetic separation between the haemoplasmas and Mycoplasmas that corresponds with the biological differences observed in these species, indicating that further evaluation of the haemoplasmas’ relationship with the Mycoplasma genus is required to determine whether reclassification of the haemoplasmas is necessary.

Abstract
Background: Glucose regulated protein 78 (GRP78) functions as a sensor of endoplasmic reticulum (ER) stress. The aim of this study was to test the hypothesis that molecules that bind to GRP78 induce the unfolded protein response (UPR) and enhance cell death in combination with ER stress inducers. Methods: Differential scanning calorimetry (DSC), measurement of cell death by flow cytometry and the induction of ER stress markers using western blotting. Results: Epigallocatechin gallate (EGCG), a flavonoid component of Green Tea Camellia sinensis, and honokiol (HNK), a Magnolia grandiflora derivative, bind to unfolded conformations of the GRP78 ATPase domain. Epigallocatechin gallate and HNK induced death in six neuroectodermal tumour cell lines tested. Levels of death to HNK were twice that for EGCG; half-maximal effective doses were similar but EGCG sensitivity varied more widely between cell types. Honokiol induced ER stress and UPR as predicted from its ability to interact with GRP78, but EGCG was less effective. With respect to cell death, HNK had synergistic effects on melanoma and glioblastoma cells with the ER stress inducers fenretinide or bortezomib, but only additive (fenretinide) or inhibitory (bortezomib) effects on neuroblastoma cells. Conclusion: Honokiol induces apoptosis due to ER stress from an interaction with GRP78. The data are consistent with DSC results that suggest that HNK binds to GRP78 more effectively than EGCG. Therefore, HNK may warrant development as an antitumour drug.

Abstract
Since 2008, government funding of the Health Service Executive (HSE) has decreased significantly. Our hospital, Cork University Hospital (CUH), implemented "cost saving" measures including scheduled operating theatre closures. We studied their affect on urological surgical activity at the hospital. A retrospective review was performed using theatre log books and theatre records to determine the number, type and training status of procedures performed for years 2009 and 2011. Scheduled theatre closures in 2011 resulted in 33 more theatre session cancelations compared to 2009. There was a reduction in the total number of procedures performed from 555 cases in 2009 to 443 in 2011 a 20.2(%) reduction. The number of "training" cases reduced from 325 (58.9%) in 2009 to 216 (48.7%) in 2011 a 10.2% reduction (Table 2). Eight out of the nine "core urology training" procedures reduced in number from 2009 to 2011 (Table 1). We have shown that scheduled theatre closures have reduced the number of procedures performed and have impacted on urology training. Scheduled theatre closures are expected to become more frequent in the future. Potential solutions to lessen the impact include providing simulation training using the Royal College of Surgeons in Ireland (RCSI) mobile skills unit during these theatre closures.

Abstract
Six ovine fetal brains were harvested 33 to 35 days postchallenge from 5 ewes, each of which was given 3000 Toxoplasma gondii oocysts on day 90 of pregnancy. Histopathologic examination of transverse sections taken at 13 levels in the fetal brains revealed the presence of toxoplasmosis-related lesions in all 6 brains. However, lesions were not randomly distributed ( P = .007); they were most numerous at the level of the optic tract, the rostral margin of the pons, and 4 mm caudal to the ansate sulcus and were absent in all sections at the level of the caudal cerebellum. Lesion distribution may be due to hemodynamic factors, differences in the expression of endothelial surface receptor molecules at the level of the blood-brain barrier, or the presence of localized permissive/inhibitory factors within the brain. The results have implications for the selection of areas of brain from aborted ovine fetuses to be examined histopathologically for laboratory diagnosis.

Abstract
OBJECTIVE The aims of this study were (1) to subjectively quantify the degree of scratching and smudging that had taken place in the junior clinic in the 9 months following the implementation of digital radiology; (2) to compare the findings with a previously published report; and (3) to identify areas in the protocol and training that can be refined to minimize future scratching and smudging. METHODS Seven sets of blank clinical photostimulable storage phosphor (PSP) plates were scanned after exposing them at 65 kV and 7 mA for 0.80 s. Scanned plates were lightly wiped with a soft cloth and alcohol, repackaged in plastic sleeves, re-exposed and rescanned. The two sets of resulting images were subjectively rated independently by two investigators for artefacts and placed in five categories. RESULTS Of all the images, approximately 75% were rated in the top 3 categories (most readable), leaving 17% and 8% in the poor and unsatisfactory categories, respectively. Mean rated values of the two image sets (before and after wiping) were not statistically different, but ratings slightly improved after cleaning the plates. CONCLUSIONS Wiping all plates to remove surface contamination may not always be necessary or desirable. Systems that are designed to minimize handling of the plates may help minimize scratching of them.

Abstract
Twenty-one cows from eight herds affected by Johne's disease were assigned to four groups: seven were not thriving and had persistent diarrhoea, six were not thriving and had intermittent diarrhoea, four were not thriving but did not have diarrhoea, and four were clinically normal. Postmortem, macroscopic lesions consistent with Johne's disease were identified in 17 of the cows and Mycobacterium avium subspecies paratuberculosis (MAP) was isolated from all of them. However, except for the fact that diarrhoea was correlated with the presence of lesions in the large intestine there was little correlation between the presence or absence of clinical signs and the lesions associated with Johne's disease. The tissue distribution of MAP was also poorly correlated with either the clinical signs or the lesions. The organism was widely distributed in 17 of the 21 cows, including three of the clinically normal animals, and was present in the mammary tissues of seven cows including two of the clinically normal animals. Three distinct histopathological patterns were observed in the affected intestines: infiltration of the lamina propria with giant cells, tuberculoid lesions, and lepromatous lesions; the lepromatous lesions were associated with extensive pathological changes.

Abstract
15167 Background: MMC related TTP/HUS has been reported between 4 and 15%, with a higher incidence in patients receiving cumulative doses of 60 mg or higher. It tends to occur within 4 months of drug administration independently of patients’ cancer status. The ability of MMC to upregulate enzymes relevant for new cytototoxic agents (topoisomerase I for CPT-11 and thymidine phosphorylase for capecitabine) make phamacobiologically based therapeutic combinations including MMC attractive. Methods: All patients (n=100) that participated in four institutional clinical studies from 2000 through 2004 were included. The studies were OSU 9947 (phase I trial of CPT-11 and MMC in solid tumors, n=31) OSU 0151 (phase II trial of CPT-11 and MMC in advanced esophageal and stomach cancer, n=41) OSU 0155 (phase II trial of CPT-11 and MMC in patients with refractory breast cancer, n=26) OSU 0330 (phase I study of capecitabine and MMC in patients with advanced GI tumors n=2). In each study, the maximum cumulative dose of MMC was 36 mg/m2. All patients were followed for clinical signs or symptoms of TTP/HUS including the presence of anemia, thrombocytopenia and renal insufficiency and had a thorough review of the peripheral smear. Results: The median cumulative dose was 12 mg/m2 (range 3–36 mg/m2). No patients met the clinical diagnosis of TTP/HUS except for one patient had anemia, thrombocytopenia and renal insufficiency but did not manifest any other findings consistent with TTP/HUS such as changes in mental status, azotemia or any other clinical symptom. The laboratory abnormalities resolved without intervention within seven days with subsequent continuation on the clinical trial. Conclusions: In this study we have demonstrated that by capping the cumulative dose of MMC to 36 mg/m2, the incidence of TTP/HUS is minimal. Furthermore, our preliminary analysis of an additional 100 patients treated with MMC at OSU shows no reported cases of TTP/HUS (additional data will be presented at the meeting). Since MMC is effective in a wide variety of solid tumors including breast, lung and GI malignancies and is inexpensive and easy to administer, further exploration of MMC in the treatment of solid malignancies is indicated including rational combination studies. No significant financial relationships to disclose.

Abstract
BACKGROUND There is significant heterogeneity in survival of patients with metastatic breast cancer who have bone-only metastasis. We studied the correlation of serum N-telopeptide (NTx), a marker of bone resorption, and its correlation with clinical outcomes in patients with metastatic breast cancer with bone-only or bone plus soft tissue metastasis. PATIENTS AND METHODS Serum was taken from 250 metastatic breast cancer patients with bone-only or bone plus soft tissue metastasis who participated in two similar randomized studies of second-line hormone therapy. An enzyme-linked immunosorbent assay specific for NTx of type I bone collagen was used to detect serum levels. RESULTS Sixty patients (24%) had elevated serum NTx levels, using the mean + 2 standard deviations (26 nanomoles Bone Collagen Equivalents per liter) of healthy women as a cut-off. The median duration of clinical benefit was significantly shorter in the group with elevated serum NTx levels compared with the group that had normal serum NTx levels (P=0.0004). Time to progression (TTP) was also significantly shorter in the patients with elevated serum NTx at 139 days compared with 220 days (P=0.0006). Median survival was also significantly shorter in patients with elevated baseline serum NTx levels at 663 days compared with 941 days (P<0.0001). CONCLUSION In this study, breast cancer patients with bone-only or bone plus soft tissue metastasis and elevated serum NTx levels have a shorter duration of clinical benefit, TTP and overall survival.

Abstract
PURPOSE To determine the effect of elevated serum HER-2/neu on the response of metastatic breast cancer patients to an aromatase inhibitor versus an antiestrogen. PATIENTS AND METHODS Five hundred sixty-two estrogen receptor-positive metastatic breast cancer patients were randomized to first-line hormone therapy with either letrozole or tamoxifen. An automated enzyme-linked immunosorbent assay was used to detect serum HER-2/neu. RESULTS For patients with normal serum HER-2/neu (70.5%), objective response rate (ORR; 39% in letrozole-treated patients v 26% in tamoxifen-treated patients; P =.008), clinical benefit (CB; 57% v 45%; P =.016), time to progression (TTP; median, 12.2 v 8.5 months; P =.0019), and time to treatment failure (TTF; median, 11.6 v 6.2 months; P =.0066) were significantly better in patients treated with letrozole. In the elevated HER-2/neu group (29.5%), there was no significant difference in ORR (17% in letrozole-treated patients v 13% in tamoxifen-treated patients; P =.45) or CB (33% v 26%; P =.31), but there was a strong trend in favor of a longer TTP with letrozole (median, 6.1 v 3.3 months; P =.0596) and a significantly longer TTF with letrozole (median, 6.0 v 3.2 months; P =.0418). Multivariate analysis revealed that elevated serum HER-2/neu was a negative predictor for ORR and TTP. CONCLUSION Patients with normal serum HER-2/neu receiving letrozole demonstrated a significantly greater ORR and CB and longer TTP and TTF than patients receiving tamoxifen. Although in patients with elevated serum HER-2/neu there was no significant difference between letrozole and tamoxifen in ORR or CB, there was a strong trend favoring longer TTP and significantly longer TTF with letrozole.

Abstract
PURPOSE To determine the effect of elevation of serum HER-2/neu on response to hormone therapy. PATIENTS AND METHODS Seven hundred nineteen metastatic patients with estrogen receptor-positive (ER(+)), progesterone receptor-positive, or both or ER status unknown breast cancer were randomized in three independent clinical trials to receive second-line hormone therapy with either megestrol acetate or an aromatase inhibitor (fadrozole or letrozole). An automated enzyme-linked immunosorbent assay specific for the extracellular domain of the HER-2/neu (c-erbB-2) oncoprotein product was used to detect serum levels. RESULTS Two hundred nineteen patients (30%) had elevated serum HER-2/neu protein levels, using the mean + 2 SD (15 ng/mL) from the serum of healthy women as an upper limit. Response to treatment was available for 711 patients. The response rate (complete responses plus partial responses plus stable disease) to endocrine therapy was 45% in 494 patients with non-elevated and 23% in 217 patients with elevated serum HER-2/neu levels (P <.0001). Median duration of treatment response (using the time to progression [TTP] variable for patients who responded) was shorter in the group with elevated serum HER-2/neu levels (11.7 months) compared with the patient group with non-elevated levels (17.4 months). TTP, time to treatment failure, and median survival (17.2 months v 29.6 months) were also significantly shorter in the patients with elevated serum HER-2/neu levels (P <.0001). CONCLUSION Patients with ER(+) and serum HER-2/neu-positive metastatic breast cancer are less likely to respond to hormone treatment and have a shorter duration of response than ER(+) and serum HER-2/neu-negative patients. Their survival duration is also shorter.

Abstract
PURPOSE Expression of ErbB-1 and ErbB-2 (epidermal growth factor receptor and HER2/neu) in breast cancer may cause tamoxifen resistance, but not all studies concur. Additionally, the relationship between ErbB-1 and ErbB-2 expression and response to selective aromatase inhibitors is unknown. A neoadjuvant study for primary breast cancer that randomized treatment between letrozole and tamoxifen provided a context within which these issues could be addressed prospectively. PATIENTS AND METHODS Postmenopausal patients with estrogen- and/or progesterone receptor-positive (ER+ and/or PgR+) primary breast cancer ineligible for breast-conserving surgery were randomly assigned to 4 months of neoadjuvant letrozole 2.5 mg daily or tamoxifen 20 mg daily in a double-blinded study. Immunohistochemistry (IHC) for ER and PgR was conducted on pretreatment biopsies and assessed by the Allred score. ErbB-1 and ErbB-2 IHC were assessed by intensity and completeness of membranous staining according to published criteria. RESULTS For study biopsy-confirmed ER+ and/or PgR+ cases that received letrozole, 60% responded and 48% underwent successful breast-conserving surgery. The response to tamoxifen was inferior (41%, P =.004), and fewer patients underwent breast conservation (36%, P =.036). Differences in response rates between letrozole and tamoxifen were most marked for tumors that were positive for ErbB-1 and/or ErbB-2 and ER (88% v 21%, P =.0004). CONCLUSION ER+, ErbB-1+, and/or ErbB-2+ primary breast cancer responded well to letrozole, but responses to tamoxifen were infrequent. This suggests that ErbB-1 and ErbB-2 signaling through ER is ligand-dependent and that the growth-promoting effects of these receptor tyrosine kinases on ER+ breast cancer can be inhibited by potent estrogen deprivation therapy.

Abstract
PURPOSE To compare two doses of letrozole (0.5 mg and 2.5 mg every day) and megestrol acetate (40 mg qid) as endocrine therapy in postmenopausal women with advanced breast cancer previously treated with antiestrogens. PATIENTS AND METHODS This double-blind, randomized, multicenter, multinational study enrolled 602 patients, all of whom were included in the primary analysis in the protocol. Patients had advanced or metastatic breast cancer with evidence of disease progression while receiving continuous adjuvant antiestrogen therapy, had experienced relapse within 12 months of stopping adjuvant antiestrogen therapy given for at least 6 months, or had experienced disease progression while receiving antiestrogen therapy for advanced disease. Tumors were required to be estrogen receptor- and/or progesterone receptor-positive or of unknown status. Confirmed objective response rate was the primary efficacy variable. Karnofsky Performance Status and European Organization for Research and Treatment of Cancer quality-of-life assessments were collected for 1 year. RESULTS There were no statistically significant differences among the three treatment groups for overall objective tumor response. Patients treated with letrozole 0.5 mg had improvements in disease progression (P =.044) and a decreased risk of treatment failure (P =.018), compared with patients treated with megestrol acetate. Letrozole 0.5 mg showed a trend (P =.053) for survival benefit when compared with megestrol acetate. Megestrol acetate was more likely to produce weight gain, dyspnea, and vaginal bleeding, and the letrozole groups were more likely to experience headache, hair thinning, and diarrhea. CONCLUSION Given a favorable tolerability profile, once-daily dosing, and evidence of clinically relevant benefit, letrozole is equivalent to megestrol acetate and should be considered for use as an alternative treatment of advanced breast cancer in postmenopausal women after treatment failure with antiestrogens.

Abstract
OBJECTIVES To determine the presence, distribution and molecular forms of the vanilloid receptor VR1, and confirm the presence and distribution of the ATP-gated ion channel P2X3 in the human urinary bladder. Materials and methods Normal urinary bladder tissues were obtained at postmortem from four subjects. Eight urinary bladder biopsies were also taken from patients with detrusor hyper-reflexia treated with intravesical resiniferatoxin. The specimens were studied using affinity-purified specific antibodies to VR1 and P2X3 by Western blotting and immunocytochemistry, and compared with immunostaining using antibodies to the pan-neuronal marker PGP 9.5 and Schwann cell marker S-100. RESULTS VR1- and P2X3-immunoreactive fine nerve fibres were scattered throughout the suburothelium of the normal bladder and cystoscopic biopsies, and traversed the muscle layer. They had a similar distribution to PGP 9.5-immunoreactive fibres, but there were fewer, suggesting localization in subsets of axons. Western blot studies showed an expected 100-kDa VR1 protein and a P2X3-immunoreactive 66-kDa protein. Conclusion VR1 and P2X3 are present in the human urinary bladder and may contribute to distinct pathophysiological states of bladder overactivity, in accord with their differential expression in sensory neurones. Intravesical vanilloids act via VR1 and are effective in the treatment of detrusor hyper-reflexia. P2X3 may represent a selective therapeutic target for other causes of overactive bladder.
