Fenestrated endovascular aortic repair of a superior mesenteric artery aneurysm using carbon dioxide angiography and intravascular ultrasound.

Superior mesenteric artery aneurysms are rare; however, current guidelines suggest they all require repair due to the high rupture and mortality rates, and endovascular repair is an effective management strategy. Iodinated contrast traditionally used in endovascular repair can cause significant complications, including severe allergic reactions and contrast-induced nephropathy in patients with chronic renal disease. Therefore, other imaging methods should be used during endovascular procedures to reduce these risks. We describe a unique and innovative approach using carbon dioxide angiography and intravascular ultrasound during fenestrated endovascular repair of an uncommon superior mesenteric artery aneurysm in a patient with severe contrast allergies.

Learning from minor injury care restructure during the COVID-19 pandemic: a phenomenological study of orthopaedic clinical leaders.

BACKGROUND: During peaks of the COVID-19 pandemic, trauma and orthopaedic departments in England have been asked to support emergency departments by providing first contact care for minor injuries. The subsequent requirement for departmental restructure has resulted in a variety of service pathways across the country. This study aimed to explore the experiences of different clinical teams and identify any consistent themes or reflections, which could be applied to continuous improvement of minor injury care. METHODS: Using a phenomenological approach, nine semistructured interviews were conducted with trauma and orthopaedic clinical leads across England whose departments provided support to minor injuries service. Detailed transcripts were then analysed to identify themes for discussion. Interviews were conducted via video conferencing in November 2020 at the end of England's second national lockdown. RESULTS: Each of the nine orthopaedic departments provided support for minor injuries, six of which involved creating a new unit. Themes included the value of collaborative working between the emergency department and orthopaedic staff across multiple professions and the benefit to patients of early definitive decision making. A common theme was reduced barriers to change during the pandemic. Examples of long-term service improvements triggered by the pandemic focus on pathways to enable consultant to provide early opinions for injured patients. CONCLUSIONS: A range of experiences have demonstrated themes in reflection from service leaders. Departments across the country should be encouraged to consider what improvements to their own service may be applied long term. Resource limitations, staff well-being and education must all be considered.

Emergency medicine response to the COVID-19 pandemic in England: a phenomenological study.

BACKGROUND: The COVID-19 pandemic has stretched EDs globally, with many regions in England challenged by the number of COVID-19 presentations. In order to rapidly share learning to inform future practice, we undertook a thematic review of ED operational experience within England during the pandemic thus far. METHODS: A rapid phenomenological approach using semistructured telephone interviews with ED clinical leads from across England was undertaken between 16 and 22 April 2020. Participants were recruited through purposeful sampling with sample size determined by data saturation. Departments from a wide range of geographic distribution and COVID-19 experience were included. Themes were identified and included if they met one of three criteria: demonstrating a consistency of experience between EDs, demonstrating a conflict of approach between emergency departments or encapsulating a unique solution to a common barrier. RESULTS: Seven clinical leads from type 1 EDs were interviewed. Thematic redundancy was achieved by the sixth interview, and one further interview was performed to confirm. Themes emerged in five categories: departmental reconfiguration, clinical pathways, governance and communication, workforce and personal protective equipment. CONCLUSION: This paper summarises learning and innovation from a cross-section of EDs during the first UK wave of the COVID-19 pandemic. Common themes centred around the importance of flexibility when reacting to an ever-changing clinical challenge, clear leadership and robust methods of communication. Additionally, experience in managing winter pressures helped inform operational decisions, and ED staff demonstrated incredible resilience in demanding working conditions. Subsequent surges of COVID-19 infections may occur within a more challenging context with no guarantee that there will be an associated reduction in A&E attendance or cessation of elective activity. Future operational planning must therefore take this into consideration.

A comprehensive hospital agile preparedness (CHAPs) tool for pandemic preparedness, based on the COVID-19 experience.

COVID-19 presents an unprecedented challenge to hospitals and the systems in which they operate. The primary exponential surge of COVID-19 cases is arguably the most devastating event a hospital will face. In some countries, these surges during the initial outbreak of the disease have resulted in hospitals suffering from significant resource strain, leading to excess patient mortality and negatively impacting staff wellbeing. As experience builds in managing these surges, it has become evident that agile, tailored planning tools are required. The comprehensive hospital agile preparedness (CHAPs) tool provides clinical planners with six key domains to consider that frequently create resource strain during COVID-19; it also allows local planners to identify issues unique to their hospital, system or region. Although this tool has been developed from COVID-19 experiences, it has potential to be modified for a variety of pandemic scenarios according to transmission modes, rates and critical care resource requirements.

Ablative Transarterial Radioembolization Improves Survival in Patients with HCC and Portal Vein Tumor Thrombus.

PURPOSE: Patients with hepatocellular carcinoma and portal vein tumor thrombus have a poor prognosis and limited therapeutic options. We sought to compare survival, tolerability, and safety in such patients treated with conventional yttrium-90 transarterial radioembolization dosimetric techniques or ablative transarterial radioembolization. MATERIALS AND METHODS: This retrospective, single-center cohort study included patients with hepatocellular carcinoma and right, left, and/or main portal vein tumor thrombus, preserved liver function (Child-Pugh class ≤ B7), and good performance status (Eastern Cooperative Oncology Group score ≤ 1) treated with yttrium-90 microspheres from 2011 to 2018 with ablative intent transarterial radioembolization (A-TARE), or conventional technique (cTARE). Statistical models were used to compare overall survival, post-treatment survival, toxicities, and prognosticators of response. RESULTS: Fifty-seven patients were included (21 [36.8%] ablative and 36 [63.2%] conventional intent). Median overall survival was 15.7 months. Compared to conventional treatment, ablative radioembolization was associated with longer median overall survival (45.3 vs 18.2 months; P = 0.003), longer post-treatment survival (19.1 vs 4.9 months; P = 0.005), a 70% lower risk of death (hazard ratio 0.30; 95% confidence interval, 0.13-0.70; P = 0.005), and improved 4-year survival (53.9% vs 11.2%). Overall survival did not differ significantly between treatment with resin and glass microspheres (27.5 vs 22.2 months; P = 0.62). Acceptable hepatic toxicities were observed after yttrium-90 administration, without statistical differences between the groups. CONCLUSION: In patients with advanced hepatocellular carcinoma and portal vein tumor thrombus, A-TARE is associated with longer survival than cTARE. Neither modality is associated with deleterious effects on liver function.

Evaluation of inter-observer variation for computed tomography identification of childhood interstitial lung disease.

Making chILD diagnoses on CT is poorly reproducible, even amongst sub-specialists. CT might best improve diagnostic confidence in a multidisciplinary team setting when augmented with clinical, functional and haematological results. http://bit.ly/327jRCw.

Prognostic Factors for Survival among Patients with Small Bowel Neuroendocrine Tumours Associated with Mesenteric Desmoplasia.

BACKGROUND: Small intestinal neuroendocrine tumours (SI NETs) represent 30-50% of small bowel neoplasms and are often associated with diverse fibrotic complications. Mesenteric fibrosis is a hallmark of SI NETs which may cause substantial morbidity and is considered an adverse feature. However, survival analyses in this group of patients are lacking. METHODS: The aim of this retrospective study was to determine the overall survival (OS) and factors affecting prognosis in a large cohort of 147 patients with SI NETs and radiological evidence of mesenteric desmoplasia from our centre. The severity of desmoplasia was graded radiologically and its effect on OS and long-term complications was assessed. The median follow-up period was 82 months. RESULTS: The median OS was 8.7 years (95% CI 6.8-9.9) with an overall 5-year survival of 71%. The univariate analysis demonstrated that an age >65 years, a liver tumour burden >50% of the hepatic parenchyma, carcinoid heart disease, chromogranin A levels >10 times the upper limit of normal, and urinary 5-hydroxyindoleacetic acid (5-HIAA) levels >5 times the upper limit of normal were poor prognosticators, while primary resection was associated with a longer OS. However, only an age >65 years and urinary 5-HIAA levels >10 times the upper limit of normal remained statistically significant after multivariate analysis. The severity of mesenteric desmoplasia did not seem to demonstrate a statistically significant relationship to OS or long-term outcomes. CONCLUSION: This study is the first comprehensive survival analysis of patients with SI NETs associated with mesenteric desmoplasia and has provided important and clinically relevant epidemiological data for this group of patients.

Portal vein pseudoaneurysm secondary to pancreatic lymphoma and biliary stent insertion: a rare cause of haemobilia.

BACKGROUND: Haemobilia, defined as bleeding from the biliary tree, is a rare entity. The most common cause of haemobilia is iatrogenic trauma, which accounts for 70% of cases. Pseudoaneurysms of the portal vein are an extremely rare cause of haemobilia with only four reported cases to date. Conservative treatment, open surgical repair and percutaneous trans hepatic stent-grafting have all been employed in these cases. This displays the lack of consensus regarding the treatment of this condition.We report the first case of a portal vein pseudoaneurysm following endoscopic common bile duct stent placement performed to relieve obstruction of the common bile duct for lymphomatous infiltration of the pancreatic head. The pseudoaneurysm was successfully treated by placement of a percutaneous trans hepatic covered stent-graft. CASE PRESENTATION: A 42-year-old man with a history of lymphomatous infiltration of the pancreatic head and recent endoscopic common bile duct stent placement presented with sudden onset large volume haematemesis. On the portal venous phase of a triple phase CT, this was found to be secondary to a portal vein pseudoaneurysm bulging into the upper portion of the indwelling biliary stent. The pseudoaneurysm was successfully treated by percutaneous trans hepatic placement of a covered vascular stent-graft. CONCLUSIONS: We report a rare case of portal vein pseudo aneurysm successfully treated by percutaneous trans hepatic portal venous covered vascular stent-graft insertion.

A rare case of atypical skull base meningioma with perineural spread.

Atypical meningioma is a rare cause of perineural tumour spread. In this report, we present the case of a 46-year-old female with an atypical meningioma of the skull base demonstrating perineural tumour spread. We describe the imaging features of this condition and its distinguishing features from other tumours exhibiting perineural spread.

Improving patient safety by implementing a new general surgical on-call rota for FY1 doctors.

Junior doctors often feel they have little control over their working environment and can feel overwhelmed by the numerous barriers to their involvement with rota design. This project aimed to overcome these barriers to change by implementing a new FY1 on-call rota, designed by junior doctors, for the surgical department at the Royal Sussex County Hospital, Brighton. A new rota was necessary since the department had recently undergone an organisational restructuring that altered the out of hours work load for FY1 doctors. To address this, the proposed new rota increased FY1 presence during weekend daytime shifts. To assess junior opinion about the old rota and the proposed new rota, a survey was sent to 32 FY1 doctors analysing their views about each rota in terms of safety, the sufficiency of cover for various shifts, and their willingness to work the rota. A direct comparison between the two rotas was also requested. A statistically significant (p<0.05, n=12, two-tailed paired T-test) increase in people agreeing with the following statements about the new rota: "The rota is safe", "This rota has sufficient FY1 cover during the weekend day shifts", and "I would be prepared to work this rota." A direct comparison revealed that FY1 doctors felt that the new rota would be safer, they would be more willing to work the new rota, and that the new rota should be implemented. Implementation occurred for the August 2014 general surgical FY1 intake and post implementation audits showed that the new FY1s felt that cover across all shifts was improved and that the new rota was safe. This project demonstrates that altering rotas can improve junior doctor's perception of patient safety, and also shows that junior team members, with departmental support, can overcome barriers to change and implement new rotas.

Improving the quality of handover by addressing handover culture and introducing a new, multi-disciplinary, team-based handover meeting.

Handover is a "major preventable cause of patient harm"[1] and this project aims to improve the quality of night handover within a teaching hospitals general medicine department, resulting in the safe transfer of patient care to the night team. Quality of handover was assessed both qualitatively, via structured qualitative interviews with trainees and a baseline survey assessing doctor's opinions of night handover, and quantitatively through the collection of a data set during regular observation of night handover. The initial intervention instituted a new handover meeting with a set time and new location and invited the night nurse practitioner to attend. A prompt card, standardised documentation, defined leadership, and an attendance register were also introduced. Successive PDSA cycles introduced technology to the intervention, enabled the nurse night practitioners to actually attend and re-branded the prompt card as an agenda. Results show a sustained reduction in length of handover from 70 minutes (n=7) to 34 minutes (n=13) post-intervention as well as a reduction in the number of distractions occurring during each handover from a mean of 14 to a mean of 8.5. An improved quality of handover was also demonstrated with an overall increase in the percentage of task handovers containing hospital number, an admitting diagnosis, comorbidities and a time allocated for the task to be performed of at least 10%. When trainees were surveyed post-implementation they unanimously identified the new handover system as safer than the previous handover process (n=30). This project demonstrates that replacing an ad-hoc system of handover with a multi-disciplinary, team based approach to handover improves handover quality. In addition it provides a useful guide to introducing a new handover meeting to a department and contains useful lessons on how to combat cultural barriers to change within a department.

Formando a los médicos del mañana

Most medical schools still pay too little attention to primary health care, partly because of a failing in comunication between governments and medical education systems. The World Federation for Medical Education has embarked on a major programme aimed at helping to improve this situation
