Axial Plane Deformity: How to Avoid It and How to Correct It

Malreductions in the axial plane (ie, length and rotation) are common when managing long bone fractures. Careful attention to detail during the initial treatment can prevent these malreductions. Various fluoroscopy-based techniques exist for the prevention of malrotation and limb-length discrepancy during surgery for fracture. If malreductions do occur, a systematic clinical and radiographic evaluation can provide the necessary information to correct rotational malreduction and limb-length discrepancy.

Expedited surgery does not increase transfusion rates for patients with geriatric hip fracture taking factor Xa inhibitors

Objectives

Geriatric patients who sustain hip fractures and are taking factor Xa inhibitors (Xa-I) experience surgical delay. Our institution developed a pharmacokinetic protocol to formally guide and expedite surgical timing for these patients. The protocol is based on the patient's renal function and timing of last Xa-I dose. For patients with impaired renal function, longer wait times are recommended. The purpose of this study was to determine the effects of this protocol for patients with geriatric hip fracture taking Xa-I.

Design

Retrospective cohort study.

Setting

Level 1 trauma center.

Patients/Participants

A total of 164 patients aged 65 and older who were taking Xa-I before admission and underwent hip fracture surgery; 68 patients in the Standard group (2014-2018) and 96 patients in the Expedited group (2020-2022, after protocol implementation).

Intervention

Hip fracture surgery.

Main Outcome Measurements

Time to surgery (TTS), transfusion rate, blood loss, 90-day complication rates.

Results

The median TTS was significantly shorter in the Expedited group (28.6 hours, interquartile range 21.3 hours) than in the Standard group (44.8 hours, interquartile range 21.1 hours) (P < .001). There were no differences in overall transfusion rates. Multivariable regression analysis demonstrated that time to surgery was not predictive of transfusion rate in all patients (OR 1.00, 95% CI 0.99-1.02, P = .652). There were no differences in blood loss or rates of 90-day complications.

Conclusion

Geriatric patients with hip fractures and taking factor Xa inhibitors may warrant earlier surgery without an increased risk of transfusion or bleeding.

Level of Evidence

Therapeutic Level III.

Differential attainment, socioeconomic factors and surgical training

INTRODUCTION

Differential attainment (DA) is the gap in levels of achievement between different groups; socioeconomic factors are thought to play a significant role in DA. The aim of this study was to review and assess the evidence for DA in early surgical training and to examine the potential influence of socioeconomic status.

METHODS

Data were obtained from the General Medical Council GMC for those taking Membership of the Royal College of Surgeons (MRCS) examinations between 2016 and 2019 and core surgical training annual review of competency progression (ARCP) outcomes between 2017 and 2019. The index of multiple deprivation (IMD) was used as a measure of socioeconomic background. Trainees were then divided into deprivation quintiles (DQ1=most deprived, DQ5=least deprived). MRCS and ARCP outcomes were compared between DQ groups using 95% confidence intervals and chi-square tests.

RESULTS

Those from lower socioeconomic backgrounds had significantly lower overall MRCS pass rates (DQ1=45.5%, DQ2=48.9% vs DQ4=59.6%, DQ5=61.5%, p<0.05) and 1st time pass rates (DQ1&2=46.6% vs DQ4&5=63.5%, p<0.001). Additionally, they had a significantly higher number of attempts required to pass MRCS (DQ 1&2=1.86 vs DQ 4&5=1.54, p<0.01). Those from lower socioeconomic backgrounds had a significantly greater proportion of unsatisfactory ARCP outcomes (DQ1&2=24.4% vs DQ 4&5=14.2%, p<0.05).

CONCLUSIONS

There is clear evidence of the influence of socioeconomic background on DA in early surgical training. However, the reasons for this are likely complex and more work is required to investigate this relationship.

EPIC: an evaluation of the psychological impact of early-phase clinical trials in cancer patients

Background

Anxiety and depression in patients with cancer is associated with decreased quality of life and increased morbidity and mortality. However, these are often overlooked and untreated. Early-phase clinical trials (EPCTs) recruit patients with advanced cancers who frequently lack future treatment options, which may lead to increased anxiety and depression. Despite this, EPCTs do not routinely consider psychological screening for patients.

Patients and methods

This prospective observational study explored levels of anxiety and depression alongside impact of trial participation in the context of EPCTs. The Hospital Anxiety and Depression Scale and the Brief Illness Perceptions Questionnaire were completed at the point of EPCT consent, the end of screening and at pre-specified time points thereafter.

Results

Sixty-four patients (median age 56 years; median Eastern Cooperative Oncology Group performance status 1) were recruited. At consent, 57 patients returned questionnaires; 39% reported clinically relevant levels of anxiety whilst 18% reported clinically relevant levels of depression. Sixty-three percent of patients experiencing psychological distress had never previously reported this. Males were more likely to be depressed (P = 0.037) and females were more likely to be anxious (P = 0.011). Changes in anxiety or depression were observed after trial enrolment on an individual level, but not significant on a population level.

Conclusions

Patients on EPCTs are at an increased risk of anxiety and depression but may not seek relevant support. Sites offering EPCTs should consider including psychological screening to encourage a more holistic approach to cancer care and consider the sex of individuals when tailoring psychological support to meet specific needs.

•

Early-phase cancer trial patients have an increased risk of anxiety and depression.

•

Patients at risk were not seeking support for anxiety and depression.

•

Male patients were more likely to be depressed; female patients were more likely to be anxious.

•

This work highlights the need to screen for psychological symptoms in patients entering early-phase trials.

Preoperative Transcutaneous Oxygen Perfusion Measurements in Predicting Atraumatic Wound Healing After Major Lower Extremity Amputation

This study examined the correlation between preoperative transcutaneous oxygen perfusion (TcPO₂) measurement and the success of wound healing after major lower extremity amputation. There is no validated consensus on how to accurately determine appropriate amputation levels. A TcPO₂ greater than 30 to 40 mm Hg is widely cited as a positive predictor of postoperative wound healing, but its validity has not been well defined. A retrospective chart review was performed for patients who underwent above-knee amputation (AKA), through-knee amputation, or below-knee amputation (BKA) at a single institution from 2012 to 2018 with preoperative TcPO₂ values and a minimum 30-day postoperative clinical follow-up. This review yielded 141 total amputations: 93 BKAs, 6 through-knee amputations, and 42 AKAs. Fifty-five amputations were unsuccessful, defined by postoperative wound dehiscence or infection. Of these, 37 were BKAs, 4 were through-knee amputations, and 14 were AKAs. There was a significant difference in preoperative TcPO₂ between the successful and unsuccessful amputations, at 46.2 and 38.3 mm Hg, respectively (P=.02). A TcPO₂ of 30 to 40 mm Hg showed a 68.8% success rate, and a TcPO₂ of less than 20 mm Hg showed an 18.2% success rate. A receiver operating characteristic curve for TcPO₂ predicting amputation success had an area under the curve of 0.53 for AKAs and 0.61 for BKAs; the diagnostic ability is far from prognostic. There is no linear association between TcPO₂ and success rate. A TcPO₂ of less than 20 mm Hg has a high positive predictive value for failure, but higher levels are not 100% predictive of wound healing success after amputation, as previously reported.

369 The Burnout Pandemic; the Effect of Socioeconomic Status and Training Programmes on Burnout in Postgraduate Trainees in the United Kingdom

Introduction

Burnout is described as a state of mental exhaustion caused by one’s professional life, and is characterised by three domains: emotional exhaustion, depersonalisation, and a reduced sense of accomplishment. The prevalence of stress is high amongst doctors, and varies by specialty, gender, trainee level, and socioeconomic status. The authors set out to examine the scale of the problem, as well as to determine the influence of both socioeconomic status and chosen training programme on burnout amongst postgraduate trainees. This would identify at risk groups, and aid in future targeted interventions.

Method

Cross-sectional data was obtained, following approval from the General Medical Council (GMC), from The National Training Survey, completed annually by all trainees in the United Kingdom. Data was then anonymised and analysed. Burnout scores were derived from the Copenhagen Burnout Inventory and are positively framed (higher scores equal lower burnout).

Results

The questionnaire was completed by 63,122 participants across 2019 and 2020. Mean burnout amongst all trainees combined was 52.40 +/- 19.29. Burnout scores from the most deprived quintile was significantly lower compared with those from the least deprived quintile; 51.02 +/- 20.64 versus 52.89 +/- 18.92 respectively (p &lt; 0.001). The highest levels of burnout were reported in Internal Medical Training, Emergency Medicine, Obstetrics and Gynaecology, and Core Surgical Training respectively.

Conclusions

Postgraduates from lower socioeconomic backgrounds are more likely to encounter burnout during training. At risk groups who may also benefit from targeted intervention include Core Surgical Trainees, requiring further examination through future studies.

Perineal reconstruction supplemented by abdominal advancement following recurrent penile cancer: Two cases

Reconstruction after excision of locoregionally recurrent penile cancer can be a surgical challenge. In this short study, we present two cases of perineal reconstruction using bilateral gracilis flaps supplemented by abdominal advancement for salvage of recurrent penile cancer, reviewing relevant literature and outlining our local approach to the perineum.

602 Specialty Training Progression from Core Surgical Training: Is There Evidence from Plastic Surgery of The Importance of Location, Location, Location?

Introduction

Obtaining a National Training Number (NTN) in Plastic Surgery is highly competitive (&lt;40 posts per year), with applicant:post ratios between 3.73 to 4.19 in 2017-2019.

Our aim was to compare deaneries for numbers successfully progressing directly from CT2 into a ST3 post in Plastic Surgery.

Method

Data for surgical trainees progressing directly from CT2 to ST3 (2017-2019) in all specialties was obtained from the GMC. The percentage of those directly progressing that obtained a Plastic Surgery NTN and the total number progressing was calculated.

Results

A total of 840 trainees obtained a NTN directly from CT2 between 2017 and 2019, 61 of whom did so in plastic surgery. Of those directly progressing, there was no significant difference between deaneries for the percentage of plastic surgery posts obtained. The highest number of trainees progressed from London deaneries (16 total (26%); 7 South, 6 NC&E, 3 NW) and the lowest number from Yorkshire and Humber (1).

Conclusions

Higher numbers of those undertaking core surgical training in London progress directly from CT2 to ST3 in Plastic Surgery. Low total numbers highlight the competitive nature of obtaining a Plastic Surgery NTN, necessitating many to undertake additional experience prior to obtaining a training number.

354 Differential Attainment in Surgical Training

Introduction

Differential attainment (DA), according to the General Medical Council (GMC), is the gap between attainment levels in different groups. Attainment measures should cover aspects that include academic performance and career progression. Two such areas in surgical training are the MRCS examinations and ARCPs, both of which are required for progression in a career in surgery.

Our aim was to investigation whether socio-economic background was a significant factor for progression in surgical training.

Method

Data from the GMC for Core Surgical Trainees (CSTs) taking the MRCS examination between 2016 and 2019 and CST ARCP outcomes between 2017 and 2019 were obtained. Socio-economic background was assessed using the Index of Multiple Deprivation (IMD). ARCP and MRCS outcomes were assessed against IMD.

Results

Trainees from IMD Q1&2 (most deprived) had a significantly higher (p &lt; 0.01) mean number of attempts (1.86) to pass MRCS examinations than trainees from IMD Q4&5 (least deprived) (1.54). IMD Q1&2 were significantly more likely to obtain unsatisfactory outcomes (24.4%) than trainees from IMD Q4&5 (14.2%) (p &lt; 0.05).

Conclusions

There is clear evidence that differential attainment exists within Core Surgical Training. The reasons for this are likely to be complex and more work is needed to further investigate the relationship.

Standing electric scooter injuries: Impact on a community

BACKGROUND

This study investigates the impact of standing electric scooter-related injuries within an entire integrated hospital system.

METHODS

We performed a retrospective review of patients involved in standing electric scooter incidents presenting throughout an urban hospital network over a 10 month period. Rates of Google searches of scooter-related terms performed locally were used as a surrogate for ride frequency. Injury, mechanism, and cost data were analyzed.

RESULTS

Data on 248 patients were reviewed. Twenty-three (9%) were under 18 years old. Loss of balance was the most common cause of injury accounting for nearly half, while tripping over a scooter 14 (6%) affected the elderly disproportionately. Eight (3%) riders wore helmets. All TBI and closed head injuries occurred in unhelmeted patients. Most incidents occurred in the street, only one in a bicycle lane. Facilities costs were greater for patients under the influence of alcohol and marijuana.

CONCLUSION

Policies related to the use of mandated safety equipment, dedicated bicycle lanes, and the proper storage of empty vehicles should be further investigated.

Orthognathic returns to theatre

The objectives of this retrospective study were to determine the unexpected return-to-theatre rate for orthognathic surgery at James Cook University Hospital and describe the reasons for return. A total of 357 consecutive orthognathic cases under two consultants over a 13-year period were included. Patients who had an unexpected return to theatre were identified and their notes analysed for data including preoperative dentofacial discrepancy, surgical movement, and reason for return. Returns to theatre for the removal of plates and planned procedures such as removal of a distractor or delayed genioplasty, were excluded. Thirteen patients required reoperation (3.6%). The commonest reason for return was malocclusion, and the majority returned within four weeks of the initial procedure. Proportionally more men returned to theatre than women, and revision was more likely to involve the mandible than the maxilla.

AB0511 INTERNATIONAL CONSENSUS ON ANCA TESTING AND INTERPRETATION BEYOND SYSTEMIC VASCULITIS

Background:

ANCA can be detected in sera from patients with autoimmune, inflammatory, infectious or neoplastic diseases.

Objectives:

To issue a Consensus Statement on ANCA testing and interpretation beyond systemic vasculitis.

Methods:

This Statement was prepared by a group of experts, based on the results of a comprehensive search in PubMed.

Results:

In certain settings beyond systemic vasculitis, ANCA may have diagnostic, clinical, and/or prognostic relevance. Testing for PR3- and MPO-ANCA by specific immunoassays should be performed in any patient with clinical features suggesting ANCA-associated vasculitis and in patients with anti-GBM disease and idiopathic interstitial pneumonia. Routine ANCA testing is not recommended in patients with connective tissue diseases (CTD), autoimmune liver diseases, inflammatory bowel diseases, infections, and/or malignancy unless there is evidence for small vessel vasculitis. ANCA testing by specific immunoassays may be useful in patients with rheumatoid arthritis, systemic sclerosis or primary Sjögren’s syndrome who have kidney disease with a nephritic sediment or in patients with systemic lupus erythematosus if a kidney biopsy shows prominent necrotizing and crescentic lesions or proliferative lupus nephritis. ANCA testing may be justified in patients with suspected autoimmune hepatitis type 1, who do not have conventional disease-related autoantibodies, or in patients with inflammatory bowel diseases in case of diagnostic uncertainty to discriminate ulcerative colitis from Crohn’s disease. In these cases, ANCA should be tested by indirect immunofluorescence since target antigens are not well characterized. ANCA against bactericidal/permeability-increasing protein may be a biomarker for deteriorating lung function and a poor prognosis in patients with cystic fibrosis.

Conclusion:

ANCA testing is clinically relevant not only in patients with manifestations suggesting systemic vasculitis, but also in patients with certain other disorders, particularly in patients with anti-GBM disease or idiopathic interstitial pneumonia.

Pain Management with Early Regional Anesthesia in Geriatric Hip Fracture Patients

BACKGROUND

Geriatric hip fracture patients are susceptible to the adverse effects of opioid-induced analgesia. Fascia iliaca blocks (FIBs) have emerged as an analgesic technique for this population. There are limited data on a preoperative FIB's effect on perioperative opioid intake. We hypothesized that preoperative FIB would reduce perioperative opioid consumption, measured in morphine milliequivalents (MMEs).

DESIGN

This is a prospective observational study.

SETTING

A level 1 trauma center in California.

PARTICIPANTS

From March 2017 to December 2017, patients 65 years and older presenting with a hip fracture received a preoperative FIB and were prospectively observed. This cohort was compared with a historical control.

INTERVENTION

All prospectively enrolled patients were given FIBs. For a single-shot FIB, a 30- to 40-mL bolus of 0.25% bupivacaine with 1:200,000 epinephrine was injected. For a continuous FIB, a bolus of 10 to 20 mL of 0.2% bupivacaine was injected, followed by a continuous infusion of 0.2% bupivacaine at 6 mL/h ending on the morning of postoperative Day 1.

RESULTS

A total of 725 patients were included in this study, with 92 in the prospectively collected cohort. The mean age of this cohort was 84.2 (standard deviation = 8.4) years, and 69.2% were female. Patients who received a preoperative FIB consumed less MME preoperatively, 18.0 (interquartile range = 6.0-44.5) versus 29.5 (interquartile range = 6.0-56.5) (P = .007), with no change in pain scores. No differences were found in postoperative opioid consumption between groups. There was no difference in MME or pain score in patients with dementia. Subgroup analysis based on fracture pattern (femoral neck and intertrochanteric) demonstrated a significant decrease in preoperative MME consumption in femoral neck fractures only, 12.0 (interquartile range = 5.0-24.0) versus 29.0 (interquartile range = 12.0-59.0) (P < .001).

CONCLUSION

FIBs reduce preoperative opioid intake and have low rates of opioid-related adverse events in geriatric hip fracture patients.

LEVEL OF EVIDENCE

The level of evidence was II.

Virtual reality for management of pain in hospitalized patients: A randomized comparative effectiveness trial

Objectives

Therapeutic virtual reality (VR) has emerged as an effective, drug-free tool for pain management, but there is a lack of randomized, controlled data evaluating its effectiveness in hospitalized patients. We sought to measure the impact of on-demand VR versus “health and wellness” television programming for pain in hospitalized patients.

Methods

We performed a prospective, randomized, comparative effectiveness trial in hospitalized patients with an average pain score of ≥3 out of 10 points. Patients in the experimental group received a library of 21 VR experiences administered using the Samsung Gear Oculus headset; control patients viewed specialized television programming to promote health and wellness. Clinical staff followed usual care; study interventions were not protocolized. The primary outcome was patient-reported pain using a numeric rating scale, as recorded by nursing staff during usual care. Pre- and post-intervention pain scores were compared immediately after initial treatment and after 48- and 72-hours.

Results

There were 120 subjects (61 VR; 59 control). The mean within-subject difference in immediate pre- and post-intervention pain scores was larger in the VR group (-1.72 points; SD 3.56) than in the control group (-0.46 points; SD 3.01); this difference was significant in favor of VR (P < .04). When limited to the subgroup of patients with severe baseline pain (≥7 points), the effect of VR was more pronounced vs. control (-3.04, SD 3.75 vs. -0.93, SD 2.16 points; P = .02). In regression analyses adjusting for pre-intervention pain, time, age, gender, and type of pain, VR yielded a .59 (P = .03) and .56 (P = .04) point incremental reduction in pain versus control during the 48- and 72-hour post-intervention periods, respectively.

Conclusions

VR significantly reduces pain versus an active control condition in hospitalized patients. VR is most effective for severe pain. Future trials should evaluate standardized order sets that interpose VR as an early non-drug option for analgesia.

Unsuspected Colchicine Overdose in a Female Patient Presenting as an Acute Abdomen

We report a case of multi-system organ failure as a result of unsuspected colchicine overdose in a patient with known gout and bulimia nervosa. The patient had initially presented with mild gastrointestinal symptoms with rapid progression to fulminant hepatic failure and multiple organ dysfunction before the causative agent was identified. The patient survived with aggressive intensive care support and ongoing medical treatment. Physicians should be aware of the risk assessment based on the ingested dose, that the clinical presentation of colchicine in toxic doses may be nonspecific with high potential for severe morbidity or death and that survival may occur despite multiple organ failure requiring aggressive support.

Severe Cardiac Failure Associated with Presumed Jellyfish Sting. Irukandji Syndrome?

We present a retrospective review of twelve cases of Irukandji syndrome associated with pulmonary oedema. This is a life-threatening envenoming due to a presumed jellyfish sting throughout Northern Australia, although only one case occurred outside North Queensland.

Patients presented with significant and ongoing pain, tachycardia and hypertension. Half the patients became hypotensive requiring inotropic support. Cardiac echocardiography revealed significant cardiac dysfunction. Six patients required ventilatory support. There was no death reported due to pulmonary oedema, but one patient died of intracerebral haemorrhage.

We believe patients may develop a toxin associated cardiomyopathy, and jellyfish other than Carukia barnesi may be responsible. As there is confusion with nomenclature, Carukia barnesi should be known as the Barnes jellyfish, and the diagnosis of cardiotoxic marine envenoming is suggested for any patient who has been stung by a jellyfish, develops no or minimal skin markings, and develops cardiogenic pulmonary oedema associated with Irukandji syndrome.

Anti-inflammatory effects of infliximab in mice are independent of tumour necrosis factor α neutralization

Infliximab (IFX) has been used repeatedly in mouse preclinical models with associated claims that anti‐inflammatory effects are due to inhibition of mouse tumour necrosis factor (TNF)‐α. However, the mechanism of action in mice remains unclear. In this study, the binding specificity of IFX for mouse TNF‐α was investigated ex vivo using enzyme‐linked immunosorbent assay (ELISA), flow cytometry and Western blot. Infliximab (IFX) did not bind directly to soluble or membrane‐bound mouse TNF‐α nor did it have any effect on TNF‐α‐induced nuclear factor kappa B (NF‐κB) stimulation in mouse fibroblasts. The efficacy of IFX treatment was then investigated in vivo using a TNF‐α‐independent Trichuris muris‐induced infection model of chronic colitis. Infection provoked severe transmural colonic inflammation by day 35 post‐infection. Colonic pathology, macrophage phenotype and cell death were determined. As predicted from the in‐vitro data, in‐vivo treatment of T. muris‐infected mice with IFX had no effect on clinical outcome, nor did it affect macrophage cell phenotype or number. IFX enhanced apoptosis of colonic immune cells significantly, likely to be driven by a direct effect of the humanized antibody itself. We have demonstrated that although IFX does not bind directly to TNF‐α, observed anti‐inflammatory effects in other mouse models may be through host cell apoptosis. We suggest that more careful consideration of xenogeneic responses should be made when utilizing IFX in preclinical models.

An unusual diaphragmatic hernia with gastric perforation and sub-acute presentation

Gastric perforation into the thoracic cavity through a diaphragmatic hernia is rare but, when it occurs, patients present in severe distress, with mortality approaching 50%. We present a unique case in which a fibrotic reaction between the stomach and the parietal pleura led to a subacute presentation upon perforation. The extra time that this afforded led to more effective multidisciplinary team management and ultimately an excellent outcome for the patient.

NSAID-induced diaphragmatic disease of the colon

One of the rare side effects of chronic usage of non-steroidal anti-inflammatory drugs is colopathy, which is characterised by colonic inflammation, ulceration and formation of diaphragms in late stages. We treated a case of colonic diaphragm disease with similar findings in our unit recently. We present the case herewith, followed by a discussion of the management of this interesting rare but benign condition.
