Orthopaedic assessment unit: a service model for the delivery of orthopaedic trauma care in a major trauma centre during the global pandemic (COVID-19).

INTRODUCTION: We describe a new service model, the Orthopaedic Assessment Unit (OAU), designed to provide care for trauma patients during the COVID-19 pandemic. Patients without COVID-19 symptoms and isolated musculoskeletal injuries were redirected to the OAU. METHODS: We prospectively reviewed patients throughput during the peak of the global pandemic (7 May 2020 to 7 June 2020) and compared with our historic service provision (7 May 2019 to 7 June 2019). The Mann-Whitney and Fisher Exact tests were used to test the statistical significance of data. RESULTS: A total of 1,147 patients were seen, with peak attendances between 11am and 2pm; 96% of all referrals were seen within 4h. The majority of patients were seen by orthopaedic registrars (52%) and nurse practitioners (44%). The majority of patients suffered from sprains and strains (39%), followed by fractures (22%) and wounds (20%); 73% of patients were discharged on the same day, 15% given follow up, 8% underwent surgery and 3% were admitted but did not undergo surgery. Our volume of trauma admissions and theatre cases decreased by 22% and 17%, respectively (p=0.058; 0.139). There was a significant reduction of virtual fracture clinic referrals after reconfiguration of services (p<0.001). CONCLUSIONS: Rapid implementation of a specialist OAU during a pandemic can provide early definitive trauma care while exceeding national waiting time standards. The fall in trauma attendances was lower than anticipated. The retention of orthopaedic staff in the department to staff the unit and maintain a high standard of care is imperative.

The impact of a managed clinical network on referral patterns of sarcoma patients in Grampian.

In 2004, the Scottish Sarcoma Managed Clinical Network (SSMCN) was established with the aim of optimising the management of patients diagnosed with sarcoma in Scotland. Clinical, radiological, oncological and pathological details of all bone and soft tissue sarcomas presenting in Scotland are registered and cases discussed in a weekly multi-centre, tele-link multidisciplinary team (MDT) forum. Sarcoma surgery and pathology assessment is undertaken in three specialist centres, Aberdeen, Edinburgh and Glasgow with oncological services provided within these units as well as in Dundee and Inverness. The aim of this study was to establish any difference in referral patterns, time to specialist review, preoperative magnetic resonance imaging scanning and whether complete margins were achieved on formal resection before and after establishment of the Scottish Sarcoma Network. A database was established of all patients presenting with sarcomas of the trunk or extremity in Grampian between 1991 and 2009. Notes for 158 patients were available for review. Seventy-nine (50%) patients presented prior to the establishment of the Scottish Sarcoma Network. Cohort analysis reveals that the establishment of the SSMCN has had a positive impact on the management of sarcoma. The number of patients undergoing formal resection by the specialist surgical team has significantly increased while the waiting time from referral to assessment by the sarcoma service has decreased.

Immune suppression and isolated severe head injury: a significant clinical problem.

In the developed world, trauma is the principal cause of death under the age of 40 and is the third largest overall killer. In the UK, approximately 25,000 people die each year as a result of major injury, 25% as a result of head injuries alone. Despite improved diagnosis and management, infection remains the commonest complication in those patients surviving the initial injury. Some 5% are reported to die as a result of septic complications. Prolonged periods of intensive care and respiratory support predispose to infective respiratory complications. These patients in the absence of significant systemic injury and, as a result of severe head injury, are unable to mount an effective immune response. This literature review examines the changes that have been reported to occur in the immune system following isolated severe head injury and explores the relationship these changes may have to the increased development of infective complications.

An unusual malignancy in a young female; urachal adenocarcinoma.

Urachal Adenocarcinoma is a rare tumour that predominantly affects men between the ages of 50-60; it presents late and is therefore associated with a poor prognosis. We discuss the presentation, investigation, treatment and prognosis of this uncommon tumour.

Hydronephrosis: unrecognized complication following restorative proctocolectomy with ileal pouch-anal anastomosis.

Restorative proctocolectomy with ileal pouch-anal anastamosis (IPAA) is the operation of choice to avoid permanent ileostomy in the surgical management of patients with ulcerative colitis and familial adenomatous polyposis coli. IPAA with two loops of small intestine (J-pouch) is the most common configuration. Mortality rates are low, and despite significant morbidity patient satisfaction remains high. Functional results are good in most cases. We present two cases of hydronephrosis following IPAA. Loin pain was the presenting symptom in both cases, with one patient developing impaired renal function. Hydronephrosis has not been reported following IPAA, but with other forms of pelvic and retroperitoneal surgery it is believed to remain largely asymptomatic. We discuss the etiology of this previously unrecognized complication and suggest that it may be more prevalent following IPAA than is realized.

Isoenzyme analysis of hyperamylasaemia associated with ruptured abdominal aortic aneurysms.

Hyperamylasaemia may occur following abdominal aortic aneurysm rupture and its use as a prognostic indicator has been suggested. However, the isoenzyme responsible for the rise in serum amylase has not been investigated. In this study, isoenzyme analysis was performed on the serum of patients noted to have a raised amylase from their routine biochemistry samples. Individual cases were then reviewed regarding clinical course and outcome. The pancreas has been thought to be the predominant source of the observed hyperamylasaemia. However, in this study a mixed picture of pancreatic and salivary isoenzymes was found. Of the four highest recorded amylase levels two were salivary in origin, one pancreatic and one mixed. The highest recorded amylase level was of salivary origin in a patient that survived without any major complication. The four patients that died all showed evidence of gut infarction/ischaemia. Two had hyperamylasaemia of a mixed pattern, one pancreatic and one of salivary origin.

Cranial fasciitis of childhood: an incidental finding of a lytic skull lesion.

We describe a case of cranial fascitis presenting as an incidental finding. A 2 1/2-year-old girl had skull radiographs performed after sustaining a minor head injury, which revealed a lytic skull lesion. We describe the salient features of the case and review the current literature of this rare benign inflammatory condition.
