Abstract
AIMS The De-ESCALaTE study showed an overall survival advantage for the administration of synchronous cisplatin chemotherapy with radiotherapy in low-risk oropharyngeal cancer when compared with synchronous cetuximab. During the trial, a radiotherapy quality assurance protocol amendment permitted centres to swap from the original radiotherapy contouring protocol (incorporating the whole oropharynx into the high-dose clinical target volume (CTV); anatomical protocol) to a protocol that incorporated the gross tumour volume with a 10 mm margin into the CTV (volumetric protocol). The purpose of this study was to examine both toxicity and tumour control related to this protocol amendment. MATERIALS AND METHODS Overall survival and recurrence at 2 years were used to compare tumour control in the two contouring cohorts. For toxicity, the cohorts were compared by both the number of severe (grades 3-5) and all grades acute and late toxicities. In addition, quality of life and swallowing were compared using EORTC-C30 and MD Anderson Dysphagia Inventory, respectively. RESULTS Of 327 patients included in this study, 185 were contoured according to the anatomical protocol and 142 by the volumetric protocol. The two cohorts were well balanced, with the exception of significantly more patients in the anatomical cohort undergoing prophylactic feeding tube insertion (P < 0.001). With a minimum of 2 years of follow-up there was no significant difference in overall survival or recurrence between the two contouring protocols. Similarly, there was no significant difference in the rate of reported severe or all grades acute or late toxicity and no sustained significant difference in quality of life. However, there was a significant difference in favour of volumetric contouring in several domains of the MD Anderson Dysphagia Inventory questionnaire at 1 year, which persisted to 2 years in the dysphagia functional (P = 0.002), dysphagia physical (P = 0.009) and dysphagia overall function (P = 0.008) domains. CONCLUSION In the context of the unplanned post-hoc analysis of a randomised trial, measurable improvement in long-term dysphagia has been shown following a reduction in the CTV. Further reductions in the CTV should be subject to similar scrutiny within the confines of a prospective study.

Abstract
AIMS To analyse outcomes and patterns of failure in patients with oropharyngeal carcinoma (OPC) treated with definitive volumetric modulated arc therapy with omission of contralateral high level II lymph nodes (HLII) and retropharyngeal lymph nodes (RPLN) in the contralateral uninvolved neck. MATERIALS AND METHODS Patients with OPC treated between January 2016 and July 2019 were retrospectively identified. In the absence of contralateral neck disease, institutional protocols allowed omission of contralateral HLII and contralateral RPLN in the additional absence of ipsilateral RPLN, soft palate/posterior pharyngeal wall primary. RESULTS In total, 238 patients with OPC and an uninvolved contralateral neck received definitive (chemo)radiotherapy with bilateral neck treatment. The median follow-up was 30.6 months. Two-year local control, regional control and overall survival were 91.0, 91.6 and 86.5%, respectively. Contralateral HLII were omitted in 159/238 (66.8%) patients; this included 106 patients in whom the primary tumour was at/crossed the midline. The contralateral RPLN region was omitted from elective target volumes for 175/238 (73.5%); this included 114 patients with a primary tumour at/crossed the midline. The mean contralateral parotid dose when contralateral HLII and RPLN were both omitted was 24.4 Gy, compared with 28.3 Gy without HLII/RPLN omission (P < 0.001). Regional progression occurred in 18/238 (7.6%) patients, all involving the ipsilateral neck with one bilateral. There were no recurrences in the contralateral HLII or RPLN regions. CONCLUSION In patients with OPC and an uninvolved contralateral neck receiving bilateral (chemo)radiotherapy, the omission of contralateral RPLN and HLII from elective target volumes was safe and could lead to reduced contralateral parotid doses.

Abstract
AIMS To report the outcomes of nasopharyngeal carcinoma in adults across three large centres in a non-endemic region in the era of intensity-modulated radiotherapy (IMRT). MATERIALS AND METHODS Adult patients with nasopharyngeal carcinoma treated in three large cancer centres with IMRT ± chemotherapy with curative intent between 2009 and 2016 were identified from institutional databases. Radiotherapy was delivered with 70 Gy in 33-35 daily fractions. A univariable analysis was carried out to evaluate the relationship of patient, tumour and treatment factors with progression-free survival (PFS) and overall survival. RESULTS In total, 151 patients were identified with a median follow-up of 5.2 years. The median age was 52 years (range 18-85). Seventy-five per cent were of Caucasian origin; 75% had non-keratinising tumours; Epstein Barr virus status was only available in 23% of patients; 74% of patients had stage III or IV disease; 54% of patients received induction chemotherapy; 86% of patients received concurrent chemotherapy. Five-year overall survival, PFS, local disease-free survival, regional disease-free survival and distant disease-free survival were 70%, 65%, 91%, 94% and 82%, respectively. Keratinising squamous cell carcinoma, older age, worse performance status, smoking and alcohol intake were associated with inferior overall survival and PFS. CONCLUSIONS Local, regional and distant disease control are relatively high following IMRT ± chemotherapy in a non-endemic population. There was considerable heterogeneity in terms of radiotherapy treatment and the use of chemotherapy, encouraging the development of treatment protocols and expert peer review in non-endemic regions.

Abstract
Background and Aim Platelet-rich fibrin (PRF) can be named as a natural fibrin-based biomaterial favorable to increasing vascularization and able to guide epithelial cell migration to its surface. The membrane has a significant positive effect on protecting open wounds and accelerating healing. Similar to PRF Ankaferd Blood Stopper (ABS) also has positive effects on wound healing. The aim of this study was to detect if we can improve known physical properties of PRF combining with ABS. This idea was based on the known mechanism of ABS in forming protein network without damaging any blood cells. Materials and Methods: A total of 25 adult rabbits used for collecting 5-7 ml of blood passively with the help of winged blood collection needle to the test tube. Collected samples were centrifuged at 3000 rpm for 10 min. Two similar samples obtained from each animal and one of the samples was placed in 20% ABS 80% saline solution for 5 min. Mechanical properties of the membrane samples were measured using Universal Testing Machine. Results: There is the statistically significant difference between PRF and ABS added PRF in elongation/mm (dL) and elongation/% at break values. Maximum force (fMax) and modulus values did not show any statistically significant differences. Conclusion ABS loaded PRF causes better physical properties. This combination seems to exhibit superior performance when used as a membrane barrier solely. Advanced studies can be done on biological properties of ABS loaded PRF, especially on tissue healing.

Abstract
AIMS To assess long-term patient-reported swallow function after chemoradiotherapy for oropharyngeal carcinoma and to evaluate the frequency of deterioration/improvement over years. MATERIALS AND METHODS Fifty-nine patients with oropharyngeal carcinoma treated with parotid-sparing intensity-modulated radiotherapy and concurrent chemotherapy between 2010 and 2012 had previously completed the MD Anderson Dysphagia Inventory (MDADI) at a median of 34 months (range 24-59) after treatment. An MDADI was posted to 55 alive and disease-free patients after a 30 month interval; 52/55 replies were received, a median of 64 months (range 52-88) after treatment; 27/52 (52%) had been managed with a prophylactic gastrostomy. A 10 point or greater change in the MDADI scores was defined as clinically significant. RESULTS Overall, in the whole cohort, patient-reported swallow function showed a small absolute improvement in MDADI composite score on the second MDADI questionnaire (>5 years after treatment) compared with the first MDADI (>2 years after treatment); mean 68.0 (standard deviation 19.3) versus 64.0 (standard deviation 16.3), P = 0.021. Using the composite score, swallow function was stable over time in 29/52 (56%) patients; a clinically significant improvement in swallow function over time was noted in 17/52 (33%) patients; conversely 6/52 (12%) patients experienced a clinically significant deterioration with time. Abnormality of pre-treatment diet and a prophylactic gastrostomy correlated with an inferior MDADI composite score on the later questionnaire (P = 0.029 and P = 0.044, respectively). CONCLUSIONS Long-term dysphagia is prevalent >5 years after treatment. Although long-term swallow function is stable in most patients, it is not static in a minority. On MDADI composite summary scores, 33% of patients experienced an improvement, whereas 12% deteriorated with time. Further investigation is needed to determine underlying mechanisms behind these divergent outcomes.

Abstract
INTRODUCTION Emergency general surgery (EGS) accounts for 50% of the surgical workload, and yet outcomes are variable and poorly recorded. The management of acute cholecystitis (AC) at a dedicated emergency surgical unit (ESU) was assessed as a performance target for EGS. METHODS The outcomes for AC admissions were compared one year before and after inception of the ESU. The impact on cost and compliance with national guidance recommending early laparoscopic cholecystectomy (ELC) within seven days of diagnosis was assessed. RESULTS The overall ELC rate increased from 26% for the 126 patients admitted in the pre-ESU period to 45% for the 152 patients admitted in the post-ESU period (p=0.001). With those unsuitable for ELC excluded, the ELC rate increased from 34% to 82% (p<0.001). The proportion of patients precluded from ELC for avoidable reasons, particularly owing to 'surgeon preference/skill', was reduced from 69% to 18% (p<0.001). The mean total length of stay (LOS) and postoperative LOS fell by 1.7 days (from 8.3 to 6.6 days, p=0.040) and 2 days (from 5.6 to 3.6 days, p=0.020) respectively. The higher ELC rate and the reduction in LOS produced additional tariff income (£111,930) and estimated savings in bed day (£90,440) and readmission (£27,252) costs. CONCLUSIONS A dedicated ESU incorporating national recommendations for EGS improves alignment of best practice with best evidence and can also result in financial rewards for a busy district general hospital.

Abstract
OBJECTIVE The purposes of this study were to determine the coexistence of mastalgia and fibromyalgia, to investigate the effects of this combination on pain patterns, and to discuss the status of breast pain in the diagnostic algorithm of fibromyalgia syndrome. METHODS Sixty-one female patients reporting breast pain during the last three months and 53 female patients diagnosed with fibromyalgia syndrome were enrolled in this study. The Breast Pain Questionnaire was administered to all participants in the mastalgia group and to those in the fibromyalgia syndrome group who had experienced mastalgia during the past three months. The patients in the fibromyalgia syndrome group were evaluated using the 2010 preliminary American College of Rheumatology classification criteria. All of the patients in the mastalgia group were evaluated for the diagnosis of fibromyalgia syndrome by a single physiatrist. The coexistence and pain patterns of mastalgia and fibromyalgia were assessed statistically. RESULTS Approximately half of the patients with fibromyalgia syndrome (47.2%) reported having mastalgia at the time of admission and 37.7% of the patients with mastalgia met the diagnostic criteria for fibromyalgia syndrome. The patients with mastalgia in the fibromyalgia syndrome group had significantly higher total breast pain scores compared with the women in the mastalgia group. In addition, the patients with fibromyalgia syndrome in the mastalgia group had significantly higher Widespread Pain Index and Symptom Severity Scale scores than the patients with fibromyalgia syndrome. CONCLUSIONS We suggest that mastalgia can be an aspect of the central sensitivity syndrome and can be added to the somatic symptoms of fibromyalgia.

Abstract
OBJECTIVE To assess the accuracy of a 4-month post-(chemo)radiotherapy 18-fludeoxyglucose ((18)F-FDG) positron emission tomography (PET)-CT for head and neck squamous cell carcinoma (HNSCC). METHODS 105 patients who underwent a baseline and response assessment (18)F-FDG PET-CT scan between 2008 and April 2013 were identified. (18)F-FDG PET-CT outcomes were analysed with reference to clinicopathological outcomes. RESULTS 79 of 105 (75%) (18)F-FDG PET-CT scans demonstrated a complete metabolic response; 19 of 101 (19%) for assessable primary tumours were positive; and 19 of 93 (20%) for patients with nodal disease were equivocal (n = 10) or positive (n = 9). The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for primary and nodal disease were 90%, 89%, 47%, 99% and 91%, 89%, 53% and 99%, respectively. Eight of nine patients with a positive nodal response scan had clinicopathological evidence of residual nodal disease (PPV, 89%). 2 of 10 patients with equivocal nodal responses had clinicopathological evidence of residual nodal disease (PPV, 20%). CONCLUSION (18)F-FDG PET-CT 4 months post treatment has a very high NPV. A positive (18)F-FDG PET-CT has a high PPV for residual nodal disease. By contrast, patients who have an equivocal nodal response have a low PPV. ADVANCES IN KNOWLEDGE Response assessment (18)F-FDG PET-CT is a valuable tool in guiding the selective use of neck dissection following (chemo)radiotherapy for HNSCC. An equivocal lymph node response has a limited predictive value for persistent disease, and optimal management remains a clinical challenge.

Abstract
INTRODUCTION Emergency surgery is changing rapidly with a greater workload, early subspecialisation and centralisation of emergency care. We describe the impact of a novel emergency surgical unit (ESU) on the definitive management of patients with gallstone pancreatitis (GSP). METHODS A comparative audit was undertaken for all admissions with GSP before and after the introduction of the ESU over a six-month period. The impact on compliance with British Society of Gastroenterology (BSG) guidelines was assessed. RESULTS Thirty-five patients were treated for GSP between December 2013 and May 2014, after the introduction of the ESU. This was twice the nationally reported average for a UK trust over a six-month period. All patients received definitive management for their GSP and 100% of all suitable patients received treatment during the index admission or within two weeks of discharge. This was a significantly greater proportion than that prior to the introduction of the ESU (57%, p=0.0001) as well as the recently reported national average (34%). The mean length of total inpatient stay was reduced significantly after the ESU was introduced from 13.7 ± 4.7 days to 7.8 ± 2.1 days (p=0.03). The mean length of postoperative stay also fell significantly from 6.7 ± 2.6 days to 1.8 ± 0.8 days (p=0.001). CONCLUSIONS A dedicated ESU following national recommendations for emergency surgery care by way of using dedicated emergency surgeons and a streamlined protocol for common presentations has been shown by audit of current practice to significantly improve the management of patients presenting to a busy district general hospital with GSP.

Abstract
A simulation software (ARRPA) has been developed in Microsoft Visual Basic platform for optimization and control of a novel membrane-integrated arsenic separation plant in the backdrop of absence of such software. The user-friendly, menu-driven software is based on a dynamic linearized mathematical model, developed for the hybrid treatment scheme. The model captures the chemical kinetics in the pre-treating chemical reactor and the separation and transport phenomena involved in nanofiltration. The software has been validated through extensive experimental investigations. The agreement between the outputs from computer simulation program and the experimental findings are excellent and consistent under varying operating conditions reflecting high degree of accuracy and reliability of the software. High values of the overall correlation coefficient (R (2) = 0.989) and Willmott d-index (0.989) are indicators of the capability of the software in analyzing performance of the plant. The software permits pre-analysis, manipulation of input data, helps in optimization and exhibits performance of an integrated plant visually on a graphical platform. Performance analysis of the whole system as well as the individual units is possible using the tool. The software first of its kind in its domain and in the well-known Microsoft Excel environment is likely to be very useful in successful design, optimization and operation of an advanced hybrid treatment plant for removal of arsenic from contaminated groundwater.

Abstract
Abstract Rheumatoid arthritis (RA) is a joint-specific disease with complex pathogenesis. It is characterized by synovial inflammation, cartilage loss, and joint destruction. The reasons why joint damage recurs when therapy is discontinued are not clearly understood. Several lines of evidence suggest that cartilage damage is promoted by the transformed and invasive fibroblast-like synoviocytes (FLS) of the rheumatoid joint. It has been demonstrated in several systems that aberrant wnt-mediated signaling causes blockade of cartilage differentiation and malformation of joints. In this review, we have discussed the importance of wnt-frizzled-mediated signaling in the autonomous activation of FLS in patients with RA. Anti-wnt/anti-frizzled antibodies, frizzled receptor antagonists, or small molecule inhibitors of wnt-frizzled signaling might be useful for therapeutic interventions in RA.

Abstract
BACKGROUND Whether to perform colorectal cancer and liver metastasis resections simultaneously or in separate procedures is controversial. The aim of the present study was to investigate the effect of the Pringle manoeuvre on the healing of left-sided colonic anastomoses in rats. METHODS Sixteen rats were randomly separated into two groups. In Groups 1 and 2, 1 cm of descending colon was resected and a primary anastomosis was performed. In Group 2, an intermittent pedicle clamp (the Pringle manoeuvre) was performed. On postoperative day 5, laparotomy was performed and the bursting pressures of all colon anastomoses were determined. Tissues were sampled for assay of hydroxyproline levels. Cultures of intraperitoneal swabs were also performed. RESULTS Clostridium was twice as abundant in the Pringle manoeuvre group as in the control group (p < 0.05). Anastomosis-bursting pressures and tissue hydroxyproline levels were significantly lower in the Pringle manoeuvre group than in the control group (p < 0.05). CONCLUSIONS The Pringle manoeuvre may compromise the viability of colonic anastomoses.

Abstract
The differences between invasive lobular and ductal carcinomas affect the diagnostic and therapeutic management for patients with breast cancer. In most cases, this can be accomplished because of distinct histomorphologic features. However, occasionally, this task may become quite difficult, in particular when dealing with the variants of infiltrating lobular carcinoma. Lobular carcinoma has been considered a variant of mucin-secreting carcinoma with only intracytoplasmic mucin. The presence of extracellular mucin is a feature of ductal carcinoma. Herein is presented a case of lobular carcinoma with extracellular and intracellular mucin in a 43-year-old female patient, and confirmed by immunohistochemistry. Up to the present, infiltrating lobular carcinoma displaying extracellular mucin has not been described in the literature except two case.

Abstract
Defining the target for head and neck radiotherapy is a critical issue with the introduction of steep dose gradients associated with intensity-modulated radiotherapy. Tumour delineation inaccuracies are a major source of error in radiotherapy planning. The integration of 18-fluoride fluorodeoxyglucose positron emission tomography ((18)FDG-PET) and magnetic resonance imaging directly into the radiotherapy planning process has the potential to greatly improve target identification/selection and delineation. This raises a range of new issues surrounding image co-registration, delineation methodology and the use of functional data and treatment adaptation. This overview will discuss the practical aspects of integrating (18)FDG-PET and magnetic resonance imaging into head and neck radiotherapy planning.
