Abstract Frostbite is a high morbidity injury caused by soft tissue freezing, which can lead to digit necrosis requiring amputation. Rapid rewarming is a first line treatment method that involves placing affected digits into a warm water bath. This study aims to assess the clinical practices for frostbite at facilities outside of dedicated burn centers, and any impact these practices have on tissue salvage. Retrospective chart review at a single burn center identified frostbite patients admitted directly or as transfers over a seven-year period. Records were reviewed to identify initial treatment strategies. If given, time to thrombolytics from admit was noted. Tissue salvage rates were calculated from radiologically derived tissue at-risk scores and final amputation scores. One-hundred patients were transferred from outside facilities, and 108 were direct admissions (N=208). There was no significant difference in group demographics. Rapid rewarming was the initial treatment modality more commonly in direct admit patients (P=0.016). The use of rapid rewarming did not correlate with tissue salvage (P=0.112). Early use of thrombolytics had a positive impact on tissue salvage (P=0.003). Thrombolytics were given 1.2 hours earlier in direct admit patients (P=0.029), however there was no difference in tissue salvage rates between the groups (P=0.127). Efforts should focus on larger scale study to further assess the effectiveness of rapid rewarming. Although rapid rewarming did not significantly impact tissue salvage in this study, we continue to recommend its use over less studied treatment methods, and continue to view it as an important bridge to burn center transfer and administration of thrombolytic therapy.

Abstract Introduction Frostbite is a high morbidity, high cost injury caused by soft tissue freezing, which can lead to digit or limb necrosis requiring amputation. Many severe frostbite injuries are initially assessed at healthcare facilities outside of dedicated burn centers. Rapid rewarming is the widely accepted first line treatment and is typically performed by placing the affected body parts in a 40–42 C water bath for 15–30 minutes. The aim of this study is to ascertain the clinical practices at the referring facilities before transferring patients with severe frostbite to regional burn centers, as well as any impact on clinical outcomes. Methods Upon IRB approval, retrospective chart review identified severe frostbite patients admitted to our ABA verified burn center between 2014 and 2019. Records were reviewed to identify initial rewarming strategy from referring facilities. Time to thrombolytics after initial admission was also noted. Amputation and salvage rates were calculated. Results Seventy-four severe frostbite patients presented to outside facilities and 96 were direct admissions (N=170). There was no significant difference in age, gender, social and comorbid characteristics between transfer and direct admit groups. We found that a significantly greater number of transfer patients received tPA versus direct admit patients (82.4% v 66.7%, P=0.023). On average, tPA was given 1.5 hours earlier in the direct admit patients (5.8 vs 7.3 hours, P=0.004). There was no significant difference in tissue at risk scores (10.2 v 9.1, P=0.465), percentage of patients requiring amputation (35.1% v 24.0%, P=0.126), or tissue salvage rates (76.8 v 84.2, P=0.207) between the two groups. In the cohort of patients presenting to outside hospitals, 66% received rapid rewarming. Other warming modalities at referring centers included warm intravenous fluids, heated blankets, heated oxygen, catheter-based warming, bladder irrigation, and heat packs. On regression analysis, the use of rapid rewarming was not a significant predictor for poor outcomes for limb salvage (P=0.578). The early use of thrombolytics had a positive outcome on limb salvage (P=0.013). Conclusions Initial rewarming practices for frostbite vary dramatically at outside centers. While rapid rewarming was not statistically associated with improved outcomes, variations in specific treatment modalities and limited sample size decrease the likelihood of identifying differences in a retrospective study. Outreach efforts are needed to educate outside centers about the importance of rapid rewarming and early transfer of severe frostbite patients to burn centers for thrombolytic therapy. Applicability of Research to Practice This study shows the need for outreach and education of frostbite management for non-burn centers.

Abstract Introduction American Burn Association guidelines recommend that all pediatric burns be transferred to a burn center if their presenting hospital lacks the necessary personnel or equipment for their care. Our institution often treats small (< 10% TBSA) burns in pediatric patients as outpatients with a non-daily dressing. The aim of this study was to determine if small pediatric burns could be managed in an outpatient manner and risk factors for failure. Methods A retrospective chart review was conducted from July 2016 to July 2019 at a single ABA-verified burn center. All patients under the age of 18 who presented for evaluation were included. Post burn day, age, sex, TBSA, burn etiology, body area burned, burn dressing type, outpatient versus inpatient management, reason(s) for admission, and any operative intervention were collected. Results In total, 742 patients were included in our cohort (Table 1). The most common burn etiologies were scald (68%), contact (20%), and flame (5%). From initial presentation, 101 patients (14%), mean TBSA 9%, were admitted to the burn unit and 641 patients (86%), mean TBSA 3%, were treated outpatient. Of those, 613 (96%) were treated entirely outpatient and 28 (4%) were admitted at a later date. There were no significant differences in age (p=0.6) nor gender distribution between those who were successfully treated outpatient and those who failed. There was a significant difference (p < 0.001) in TBSA between the patients who were treated successfully as outpatients (3±2%) versus those who failed outpatient care (4±3%). The primary reason for admission of these patients was nutrition optimization (61%). Conclusions The vast majority of small pediatric burns can be treated as an outpatient with a non-daily dressing with good results. Over 80% of pediatric patients seen in our clinic were successfully managed in this manner. As suspected, when the burns are larger in size (>4% TBSA) there is a potential increased risk for admission especially with regards to poor PO intake, so this requires close monitoring and family education. Applicability of Research to Practice Pediatric patients with small burns can be safely managed in an outpatient setting with a non-daily dressing. Those who fail will most likely fail from poor PO intake at home.

750 Background: Optimal sequencing of therapies in synchronous metastatic rectal cancer (SMRC) remains unknown. Aim: To compare sequencing of treatment modality and outcomes in SMRC. Methods: Retrospective audit of patients with SMRC registered on the multi-centre Treatment of Recurrent and Advanced Colorectal Cancer database between 1/1/2009 and 30/6/2015. Patients were grouped according to initial treatment mode: chemotherapy (C), chemoradiation (CRT), surgery (S) and best supportive care (BSC). Results: 247 patients were identified: median age was 62yrs, ECOG 0-1 87%, male 64%, 1-2 metastatic sites 86% (liver 56%) and treatment intent was curative in 14%. Median follow-up was 19m. Primary tumour resection occurred in 95 patients (38%). Compared to no resection, these patients had improved median OS (41 vs 16 months; p < 0.0001) and PFS (15 vs 10 months; p < 0.0001). There was no difference in outcome with varying treatment combinations and sequences of S with CRT/C (p > 0.05). For unresected patients, the most common initial treatment was C (30%). Any active treatment was associated with better OS compared to BSC (6.4m): C (16.1m, p < 0.0001), CRT (20.6m, p = 0.001) and C&CRT (21.8m, p < 0.0001). Most active treatments were associated with better PFS compared to BSC (6.4m): C (10.8m, p = 0.015) and C&CRT (10.6m, p = 0.012). There was no significant PFS difference comparing BSC to CRT (p = 0.25). There were no OS nor PFS differences between: comparisons of C, CRT and C&CRT (p > 0.05). Initial treatment strategies were compared for 129 patients receiving multimodal therapy, where 22 (17%) had initial treatment with C (60% subsequent resection) compared to 85 (66%) commencing with CRT (70% subsequent resection). Commencing with CRT was associated with a longer OS compared to C (31 vs 21 months; p = 0.014). Conclusions: For patients undergoing primary tumour resection, no difference in outcomes were demonstrated with the addition of C and/or CRT. For unresected patients, there was a survival benefit associated with active therapy, with no significant difference between C, CRT or C&CRT. This supports the current practice of using these modalities at clinicians’ discretion. Review of patient factors potentially influencing treatment choice is ongoing.

Abstract Acute necrotizing pancreatitis (ANP) is a severe form of acute pancreatitis that is associated with high morbidity and mortality. Thus, an adequate initial treatment of patients who present with acute pancreatitis (AP) based on correct interpretation of early detected laboratory and clinical abnormalities may have a significant positive impact on the disease course. The aim of the study was to determine patient- and initial treatment-related risk factors for the development of acute necrotizing pancreatitis. For the purpose of this study a case-control design was chosen, including adult patients treated for AP in the surgical Intensive Care Unit (sICU) of Clinical Center of Kragujevac, from January 2006 to January 2011. The cases (n=63) were patients who developed ANP, while the controls (n=63) were patients with AP without the presence of pancreatic necrosis. The controls were randomly selected from a study sample after matching with the cases by age and sex. Significant association with the development of ANP was found for the presence of comorbidity (adjusted OR 6.614 95%CI 1.185-36.963), and the use of somatostatin (adjusted OR 7.460, 95%CI 1.162-47.833) and furosemide (adjusted OR 2710.57, 95%CI 1.996-56.035) started immediately upon admission to the sICU. This study suggests that comorbidities, particularly the presence of serious cardio-vascular disease, can increase the risk for development of acute necrotizing pancreatitis. The probability for the development of ANP could be reduced by the avoidance of the initial use of loop diuretics and somatostatin.

This paper examines the accounting performance of the Islamic banking among (??) commercial banks in Malaysia. A total of 18 commercial banks which include 4 Islamic banks are selected as samples covering the period of 2000 - 2006. Accounting performance is measured by the return on assets (ROA) and return on equity (ROE). The objective of the study is (1) to determine whether Islamic banking performance is at par with the conventional banking and (2) to investigate whether the type (Islamic or conventional bank) and age of bank influence the performance. Result of the independence t-test of the study shows that there is no significant difference in the performance of the Islamic and the conventional banking in Malaysia although the mean score for conventional banking is higher. The regression results show that the age of banks has a positive impact on the bank performance where as none of the types of banks influence performance.

OBJECTIVEIntraoperative neuromonitoring (IOM), particularly of somatosensory-evoked potentials (SSEPs) and motor-evoked potentials (MEPs), evolved as standard of care in a variety of neurosurgical procedures. Case series report a positive impact of IOM for elective microsurgical clipping of unruptured intracranial aneurysms (ECUIA), whereas systematic evaluation of its predictive value is lacking. Therefore, the authors analyzed the neurological outcome of patients undergoing ECUIA before and after IOM introduction to this procedure.METHODSThe dates of inclusion in the study were 2007–2014. In this period, ECUIA procedures before (n = 136, NIOM-group; 2007–2010) and after introduction of IOM (n = 138, IOM-group; 2011–2014) were included. The cutoff value for SSEP/MEP abnormality was chosen as an amplitude reduction ≥ 50%. SSEP/MEP changes were correlated with neurological outcome. IOM-undetectable deficits (bulbar, vision, ataxia) were not included in risk stratification.RESULTSThere was no significant difference in sex distribution, follow-up period, subarachnoid hemorrhage risk factors, aneurysm diameter, complexity, and location. Age was higher in the IOM-group (57 vs 54 years, p = 0.012). In the IOM group, there were 18 new postoperative deficits (13.0%, 5.8% permanent), 9 hemisyndromes, 2 comas, 4 bulbar symptoms, and 3 visual deficits. In the NIOM group there were 18 new deficits (13.2%; 7.3% permanent, including 7 hemisyndromes). The groups did not significantly differ in the number or nature of postoperative deficits, nor in their recovery rate. In the IOM group, SSEPs and MEPs were available in 99% of cases. Significant changes were noted in 18 cases, 4 of which exhibited postoperative hemisyndrome, and 1 suffered from prolonged comatose state (5 true-positive cases). Twelve patients showed no new detectable deficits (false positives), however 2 of these cases showed asymptomatic infarction. Five patients with new hemisyndrome and 1 comatose patient did not show significant SSEP/MEP alterations (false negatives). Overall sensitivity of SSEP/MEP monitoring was 45.5%, specificity 89.8%, positive predictive value 27.8%, and negative predictive value 95.0%.CONCLUSIONSThe assumed positive impact of introducing SSEP/MEP monitoring on overall neurological outcome in ECUIA did not reach significance. This study suggests that from a medicolegal point of view, IOM is not stringently required in all neurovascular procedures. However, future studies should carefully address high-risk patients with complex procedures who might benefit more clearly from IOM than others.

OBJECTIVEThe prevalence of trigeminal neuralgia (TN) in patients with multiple sclerosis (MS-TN) is higher than in the general population (idiopathic TN [ITN]). Glycerol rhizotomy (GR) is a percutaneous lesioning surgery commonly performed for the treatment of medically refractory TN. While treatment for acute pain relief is excellent, long-term pain relief is poorer. The object of this study was to assess the efficacy of percutaneous retrogasserian GR for the treatment of MS-TN versus ITN.METHODSA retrospective chart review was performed, identifying 219 patients who had undergone 401 GR procedures from 1983 to 2018 at a single academic institution. All patients were diagnosed with medically refractory MS-TN (182 procedures) or ITN (219 procedures). The primary outcome measures of interest were immediate pain relief and time to pain recurrence following initial and repeat GR procedures. Secondary outcomes included medication usage and presence of periprocedural hypesthesia.RESULTSThe initial pain-free response rate was similar between groups (p = 0.726): MS-TN initial GR 89.6%; MS-TN repeat GR 91.9%; ITN initial GR 89.6%; ITN repeat GR 87.0%. The median time to recurrence after initial GR was similar between MS-TN (2.7 ± 1.3 years) and ITN (2.1 ± 0.6 years) patients (p = 0.87). However, there was a statistically significant difference in the time to recurrence after repeat GR between MS-TN (2.3 ± 0.5 years) and ITN patients (1.2 ± 0.2 years; p < 0.05). The presence of periprocedural hypesthesia was highly predictive of pain-free survival (p < 0.01).CONCLUSIONSPatients with MS-TN achieve meaningful pain relief following GR, with an efficacy comparable to that following GR in patients with ITN. Initial and subsequent GR procedures are equally efficacious.

OBJECTIVETraumatic brain injury is a major sequela of nonaccidental trauma (NAT) that disproportionately affects young children and can have lasting sequelae. Considering the potentially devastating effects, many hospitals develop parent education programs to prevent NAT. Despite these efforts, NAT is still common in Western New York. The authors studied the incidence of NAT following the implementation of the Western New York Shaken Baby Syndrome Education Program in 1998.METHODSThe authors performed a retrospective chart review of children admitted to our pediatric hospital between 1999 and 2016 with ICD-9-CM and ICD-10-CM codes for types of child abuse and intracranial hemorrhage. Data were also provided by the Safe Babies New York program, which tracks NAT in Western New York. Children with a diagnosis of abuse at 0–24 months old were included in the study. Children who suffered a genuine accidental trauma or those with insufficient corroborating evidence to support the NAT diagnosis were excluded.RESULTSA total of 107 children were included in the study. There was a statistically significant rise in both the incidence of NAT (p = 0.0086) and the incidence rate of NAT (p = 0.0235) during the study period. There was no significant difference in trendlines for annual NAT incidence between sexes (y-intercept p = 0.5270, slope p = 0.5263). When stratified by age and sex, each age group had a distinct and statistically significant incidence of NAT (y-intercept p = 0.0069, slope p = 0.0374).CONCLUSIONSDespite educational interventions targeted at preventing NAT, there is a significant rise in the trend of newly reported cases of NAT, indicating a great need for better injury prevention programming.

BACKGROUND Immersive virtual reality (VR) games are increasingly becoming part of everyday life. Several studies support immersive VR technology as a treatment method for mental health problems. There is however minimal research into the feasibility, prevalence, and quality of commercially available VR games on commercial platforms as tools for treatment or add on to treatment of mental health problems. OBJECTIVE The aim of this study was to explore the prevalence, feasibility and quality of commercially available games related to psychotherapy on a commercially available platform. METHODS We performed a search for keywords related to diagnosis and treatment strategies of mental health problems. The search was performed during March 27th on STEAM (VR content and gaming platform). A usability scale was used as a tool to look at the interaction and usability of the games, the VR-UI-UX-8. The tool contains 8 statements about usability scored 0-10, 0 indicating “Not at all” and 10 indicating “very much so”. The score ranges from 0-80 with a higher score indicating worse usability. RESULTS In total, 516 hits were found, 371 unique games. After the games were reviewed, 83 games passed the inclusion criteria, were purchased and played. Majority of the games which were excluded were either not connected to mental health, contained violence, adult content or were in other ways irrelevant or inappropriate. The mean score for the games on the VR-UI-UX-8 was 16.5 (standard deviation 15.8) with a range from 0-68. Most relevant and feasible games were found in the search words meditation, mindfulness, and LSD. CONCLUSIONS Commercial platforms hold great potential for VR games with psychotherapeutic components. The platforms are only at the beginning of the development towards serious games, e-learning and psychotherapeutic treatments. Currently the quality and usability for clinical and at home applicability are scarce, but hold great potential.

Abstract Background Few mortality-scoring models are available for solid tumor patients who are predisposed to develop Escherichia coli–caused bloodstream infection (ECBSI). We aimed to develop a mortality-scoring model by using information from blood culture time to positivity (TTP) and other clinical variables. Methods A cohort of solid tumor patients who were admitted to hospital with ECBSI and received empirical antimicrobial therapy was enrolled. Survivors and non-survivors were compared to identify the risk factors of in-hospital mortality. Univariable and multivariable regression analyses were adopted to identify the mortality-associated predictors. Risk scores were assigned by weighting the regression coefficients with corresponding natural logarithm of the odds ratio for each predictor. Results Solid tumor patients with ECBSI were distributed in the development and validation groups, respectively. Six mortality-associated predictors were identified and included in the scoring model: acute respiratory distress (ARDS), TTP ≤ 8 h, inappropriate antibiotic therapy, blood transfusion, fever ≥ 39 °C, and metastasis. Prognostic scores were categorized into three groups that predicted mortality: low risk (< 10% mortality, 0–1 points), medium risk (10–20% mortality, 2 points), and high risk (> 20% mortality, ≥ 3 points). The TTP-incorporated scoring model showed excellent discrimination and calibration for both groups, with AUC being 0.833 vs 0.844, respectively, and no significant difference in the Hosmer–Lemeshow test (6.709, P = 0.48) and the chi-square test (6.993, P = 0.46). Youden index showed the best cutoff value of ≥ 3 with 76.11% sensitivity and 79.29% specificity. TTP-incorporated scoring model had higher AUC than no TTP-incorporated model (0.837 vs 0.817, P < 0.01). Conclusions Our TTP-incorporated scoring model was associated with improving capability in predicting ECBSI-related mortality. It can be a practical tool for clinicians to identify and manage bacteremic solid tumor patients with high risk of mortality.
