Abstract:
Aims Laparoscopy is used to both investigate acute RIF pain and treat the findings of an inflamed appendix. This study investigates the histology of appendixes where the clinical diagnosis was unclear on presentation and the investigative imaging was inconclusive. Methods Retrospective data collection between January – June 2014 of all appendectomies. Data was collected from Theatre logbooks and the Pathology and PACS computer systems, and analysed in Microsoft Excel. Results 50 patients had an undiagnosed cause of RIF pain. 15% (n = 34) had an USS and 7% (n = 16) had a CT. 58% (n = 29) of scans were reported as negative/inconclusive for appendicitis. All 29 patients had a DL and appendicectomy and 45% (n = 13) were histologically reported as appendicitis. There was 3% (n = 1) associated morbidity and 0% mortality. Conclusion The appendix should be removed when faced with a diagnostic uncertainty and no other pathology is found. The advancement of laparoscopic skills and training has led to low morbidity and mortality as supported by this study. We conclude it is safer to remove the appendix than to leave it in. Key statement The presentation of an acute right iliac fossa pain can sometimes be clinically difficult to diagnose. When investigations are normal or inconclusive and symptoms persist the advancement of laparoscopic surgery allows us to perform diagnostic laparoscopy. When there is no obvious pathology found the appendix should still be removed.

Abstract:
Aims: This study investigates the histological appearance of appendixes from laparoscopic and open appendicectomies. We propose that the negativity rate of laparoscopic appendicectomies is when compared to an open appendicectomy due to the advancements in laparoscopic equipment and surgeon skills. Methods Retrospective data collection of all appendicectomies between January – June 2014. Data was collected from Theatre logbooks and the Pathology and PACS computer systems, and analysed in Microsoft Excel. Results 226 appendectomies were performed on the emergency-operating list. 174 (77%) had a laparoscopic appendicectomy and 52(23%) had an open procedure. The negative appendix rate on histology was significantly higher in the laparoscopic group (28.2%, n = 49) versus the open group (11.5%, n = 6) p = 0.05. There was a 2% (n = 5) associated morbidity and 0% mortality. Conclusion Laparoscopic surgery is considered to be a minimally invasive surgical procedure with low associated risks. The appendix is removed when inflamed and often in right iliac fossa pain when no other pathology is found. Our study shows that laparoscopy may be overused resulting in higher than expected negativity rates. Key statement Laparoscopic surgery is fast becoming the preferred operative procedure for the suspected appendicitis diagnostic tool in the unclear presentation of right iliac fossa pain. The minimally invasive procedure is considered to be a safe procedure perhaps resulting in its overuse. We investigate the negativity rate in laparoscopic verses open appendicectomy.

Abstract:
Background: Convincing arguments for either removing or leaving in-situ a macroscopically normal appendix have been made, but rely on surgeons' accurate intra-operative assessment of the appendix. This study aimed to determine the inter-rater reliability between surgeons and pathologists from a large, multicentre cohort of patients undergoing appendicectomy. Materials and methods: The Multicentre Appendicectomy Audit recruited consecutive patients undergoing emergency appendicectomy during April and May 2012 from 95 centres. The primary endpoint was agreement between surgeon and pathologist and secondary endpoints were predictors of this disagreement. Results: The final study included 3138 patients with a documented pathological specimen. When surgeons assessed an appendix as normal (n=496), histopathological assessment revealed pathology in a substantial proportion (n=138, 27.8%). Where surgeons assessed the appendix as being inflamed (n=2642), subsequent pathological assessment revealed a normal appendix in 254 (9.6%). There was overall disagreement in 392 cases (12.5%), leading to only moderate reliability (Kappa 0.571). The grade of surgeon had no significant impact on disagreement following clinically normal appendicectomy. Females were at the highest risk of false positives and false negatives and pre-operative computed tomography was associated with increased false positives. Conclusions: This multi-centre study suggests that surgeons' judgements of the intra-operative macroscopic appearance of the appendix is inaccurate and does not improve with seniority and therefore supports removal at the time of surgery.

Abstract:
Background: Head and neck cancer is an important cause of ill health. Survival appears to be improving but the reasons for this are unclear. They could include evolving aetiology, modifications in care, improvements in treatment or changes in lifestyle behaviour. Observational studies are required to explore survival trends and identify outcome predictors. Methods: We are identifying people with a new diagnosis of head and neck cancer. We obtain consent that includes agreement to collect longitudinal data, store samples and record linkage. Prior to treatment we give participants three questionnaires on health and lifestyle, quality of life and sexual history. We collect blood and saliva samples, complete a clinical data capture form and request a formalin fixed tissue sample. At four and twelve months we complete further data capture forms and send participants further quality of life questionnaires. Discussion: This large clinical cohort of people with head and neck cancer brings together clinical data, patient-reported outcomes and biological samples in a single co-ordinated resource for translational and prognostic research.

Abstract:
BACKGROUND: Systematic evidence of the contribution made by laboratory medicine to patient outcomes and the overall process of healthcare is difficult to find. An understanding of the value of laboratory medicine, how it can be determined, and the various factors that influence it is vital to ensuring that the service is provided and used optimally. CONTENT: This review summarizes existing evidence supporting the impact of laboratory medicine in healthcare and indicates the gaps in our understanding. It also identifies deficiencies in current utilization, suggests potential solutions, and offers a vision of a future in which laboratory medicine is used optimally to support patient care. SUMMARY: To maximize the value of laboratory medicine, work is required in 5 areas: (a) improved utilization of existing and new tests; (b) definition of new roles for laboratory professionals that are focused on optimizing patient outcomes by adding value at all points of the diagnostic brain-to-brain cycle; (c) development of standardized protocols for prospective patient-centered studies of biomarker clinical effectiveness or extraanalytical process effectiveness; (d) benchmarking of existing and new tests in specified situations with commonly accepted measures of effectiveness; (e) agreed definition and validation of effectiveness measures and use of checklists for articles submitted for publication. Progress in these areas is essential if we are to demonstrate and enhance the value of laboratory medicine and prevent valuable information being lost in meaningless data. This requires effective collaboration with clinicians, and a determination to accept patient outcome and patient experience as the primary measure of laboratory effectiveness.

Abstract:
Background Rupture of the Achilles tendon may result in reduced functional activity and reduced plantar flexion strength. These changes may arise from elongation of the Achilles tendon. An observational study was performed to quantify the Achilles tendon resting angle (ATRA) in patients following Achilles tendon rupture, surgical repair, and rehabilitation, respectively. Methods Between May 2012 and January 2013, 26 consecutive patients (17 men), with a mean (standard deviation, SD) age of 42 (8) years were included and evaluated following injury, repair, and at 6 weeks, 3 months, 6 months, 9 months, and 12 months, respectively (rehabilitation period). The outcome was measured using the ATRA, Achilles tendon total rupture score (ATRS), and heel-rise test. Results Following rupture, the mean (SD) absolute ATRA was 55 (8)degree for the injured side compared with 43 (7)degree(p < 0.001) for the noninjured side. Immediately after repair, the angle reduced to 37 (9)degree(p < 0.001). The difference between the injured and noninjured sides, the relative ATRA, was -12.5 (4.3)degree following injury; this was reduced to 7 (7.9)degree following surgery (p < 0.001). During initial rehabilitation, at the 6-week time point, the relative ATRA was 2.6 (6.2)degree(p = 0.04) and at 3 months it was -6.5 (6.5)degree(p < 0.001). After the 3-month time point, there were no significant changes in the resting angle. The ATRS improved significantly (p < 0.001) during each period up to 9 months following surgery, where a score of 85 (10)degreewas reported. The heel-rise limb symmetry index was 66 (22)% at 9 months and 82 (14)% at 12 months. At 3 months and 6 months, the absolute ATRA correlated with the ATRS (r = 0.63, p = 0.001, N = 26 and r = 0.46, p = 0.027, N = 23, respectively). At 12 months, the absolute ATRA correlated with the heel-rise height (r = -0.63, p = 0.002, N = 22). Conclusion The ATRA increases following injury, is reduced by surgery, and then increases again during initial rehabilitation. The angle also correlates with patient-reported symptoms early in the rehabilitation phase and with heel-rise height after 1 year. The ATRA might be considered a simple and effective means to evaluate Achilles tendon function 1 year after the rupture.

Abstract:
Many patients will require extrication following a motor vehicle collision (MVC). Little information exists on the time taken for extrication or the factors which affect this time. To derive a tool to predict the time taken to extricate patients from MVCs. A prospective, observational derivation study was carried out in the West Midland Fire Service's metropolitan area. An expert group identified factors that may predict extrication time-the presence and absence of these factors was prospectively recorded at eligible extrications for the study period. A step-down multiple regression method was used to identify important contributing factors. Factors that increased extrication times by a statistically significant extent were: a physical obstruction (10 min), patients medically trapped (10 min per patient) and any patient physically trapped (7 min). Factors that shortened extrication time were rapid access (-7 min) and the car being on its roof (-12 min). All these times were calculated from an arbitrary time (which assumes zero patients) of 8 min. This paper describes the development of a tool to predict extrication time for a trapped patient. A number of factors were identified which significantly contributed to the overall extrication time.

Abstract:
Creating trustworthy research knowledge within the qualitative research interview requires a high level of interpersonal sensitivity and reflexivity. This paper describes how ethical, phenomenological and hermeneutical dimensions are present during the qualitative research interview (QRI) and further discuss their interconnectedness and significance on the overall trustworthiness of the data created. The quality of any qualitative research interview is related to and dependent upon an open approach and the expertise of the researcher to meet ethical, phenomenological and hermeneutical challenges that arise.
