Abstract
INTRODUCTION The spleen is one of the frequently injured solid organs in abdominal blunt trauma. The standard of care is nonoperative nowadays depending on the hemodynamic stability (World Society of Emergency Surgery (WSES) grade I-III) of the patient due to advancements in treating modalities. Operative interventions are required in hemodynamically unstable patients or failure of nonoperative management. The study was planned to find the clinical spectrum of abdominal blunt trauma, specifically those having splenic trauma, and their subsequent management in an institution. METHODS This is a retrospective observational study. All included patients with blunt abdominal injuries were treated in a level 1 trauma center between July 2021 and December 2022. Data regarding demographic profile, blood transfusion, pre- and postoperative findings, and management including the period of hospital stay, morbidity, and mortality were collected and analyzed. RESULTS One hundred sixty-four patients were analyzed, of which 142 were males and 22 were females. The commonest mechanism of injury was motor vehicle collision, followed by falls. Grade III splenic injury was the most common injury, while the predominantly associated injury was rib fracture. The patients were managed preferably through nonoperative management, followed by angioembolization and operative management. The commonest postoperative complication was pneumonia. CONCLUSIONS Nonoperative management of splenic trauma has evolved as the standard of care replacing operative management in order to sustain its immune function, thereby preventing overwhelming post-splenectomy infection.

Abstract
Background: Loss of muscle mass, and its strength, is associated with adverse outcomes in many medical and surgical conditions. Trauma patients may get malnourished during their hospital course due to many interrelated contributing factors. However, there is insufficient knowledge on the acute muscle and fat changes in young trauma patients in the early days post-admission. Objective: to explore the diagnosis, feeding status, and outcome of muscle mass loss among young abdominal polytrauma patients. Methods: It was a retrospective study including hospitalized abdominal trauma patients who underwent an abdominal computerized tomographic (CT) examination initially and a follow-up one week later. CT scan-based automatic and manual analysis of the muscles and fat of the abdominal region was calculated and compared. Also, we evaluated the feeding and nutritional values to explore the adequacy of the provided calories and proteins and the potential influence of enteral feeding on the CT-based parameters for muscle loss and fat depletion. Results: There were 138 eligible subjects with a mean age of 32.8 ± 13.5 years; of them, 92% were males. Operative interventions were performed on two-thirds of the patients, including abdominal surgery (43%), orthopedic surgeries (34%), and neurosurgical procedures (8.1%). On admission, 56% received oral feeding, and this rate slightly increased to 58.4% after the first week. Enteral feed was prescribed for the remaining, except for two patients. The percentage of change in the total psoas muscle area was significantly reduced after one week of admission in patients on enteral feed as compared to those in the oral feeding group (p = 0.001). There were no statistically significant differences in the percentages of changes in the CT scan findings except for the total psoas muscle area (p = 0.001) and para-spinal muscle area (p = 0.02), which reduced significantly in the those who underwent laparotomy as compared to those who did not need laparotomy. Trauma patients who underwent emergency abdominal surgery lost muscle and fat over time. Conclusions: Loss of muscle mass and body fat is not uncommon among young trauma patients. Patients who underwent laparotomy are more likely to be affected. Further larger studies are needed to assess the specific features in the younger trauma population and how far this can be influenced by the nutrition status and its impact on the clinical outcomes. It could be early or impending stages of sarcopenia linked to trauma patients, or just acute changes in the muscle and fat, that need further investigation and follow-up after hospital discharge.

Abstract
Introduction Abdominal vascular injuries are associated with significant morbidity and mortality. Treatment options include non-operative management, open repair, and endovascular procedures. This study aimed to characterize patients and detail treatment modalities among those who sustained a traumatic abdominal vascular injury. Methods A six-year descriptive retrospective study was conducted at a level 1 trauma center and included all adult patients who sustained an abdominal vascular injury. Data abstracted included demographics, admitting characteristics, mechanism of injury, admitting vitals, injury details, diagnostic and treatment information, hospital course, and follow-up data. Results Fifty-seven patients were admitted with abdominal vascular injuries, however, 14 patients sustained injuries to smaller vascular branches and were excluded. Most vascular injuries involved the iliac artery (27.9%, n = 12), abdominal aorta (25.6%, n = 11), and inferior vena cava (25.6%, n = 11). Twenty-seven percent (n = 12) of patients sustained an injury to more than one vascular structure. Thirty-four percent of patients (n = 15) died before treatment of the abdominal vascular injury. Among the 28 patients (65.1%) treated for their vascular injuries, 46.4% (n = 13) were treated with open surgery, 32.1% (n = 9) were treated non-operatively, and 21.4% (n = 6) with coil embolization. Sixty-four percent of the patients (n = 18) who survived to discharge presented for follow-up care with a mean follow-up period of 3 ± 4.1 months. There were no vascular reinterventions after discharge for patients who followed up with our hospital. Conclusions Study findings suggested that appropriately selected cases of traumatic vascular injuries may be managed non-operatively and safely, as there were no mortalities, complications, or reinterventions among these patients.

Abstract
OBJECTIVE As obesity rates climb, it is important to study its effects on motor vehicle safety due to differences in restraint interaction and biomechanics. Previous studies have shown that an abdominal seatbelt sign (referred hereafter as seatbelt sign) sustained from motor vehicle crashes (MVCs) is associated with abdominal trauma when located above the anterior superior iliac spine (ASIS). This study investigates whether placement of the lap belt causing a seatbelt sign is associated with abdominal organ injury in occupants with increased body mass index (BMI). We hypothesized that higher BMI would be associated with a higher incidence of superior placement of the lap belt to the ASIS level, and a higher incidence of abdominal organ injury. METHODS A retrospective data analysis was performed using 230 cases that met inclusion criteria (belted occupant in a frontal collision that sustained at least one abdominal injury) from the Crash Injury Research and Engineering Network (CIREN) database. Computed tomography (CT) scans were rendered to visualize fat stranding to determine the presence of a seatbelt sign. 146 positive seatbelt signs were visualized. ASIS level was measured by adjusting the transverse slice of the CT to the visualized ASIS level, which was used to determine seatbelt sign location as superior, on, or inferior to the ASIS. RESULTS Obese occupants had a significantly higher incidence of superior belt placement (52%) vs on-ASIS placement (24%) compared to their normal (27% vs 67%) BMI counterparts (p < 0.001). Notable trends included obese occupants with superior placement having less abdominal organ injury incidence than those with on-ASIS belt placement (42% superior placement vs 55% on-ASIS). In non-obese occupants, there was a higher incidence of abdominal organ injury with superior lap belt placement compared to on-ASIS placement counterparts (Normal BMI: 62% vs 41%, Overweight: 57% vs 43%). CONCLUSIONS In CIREN occupants with abdominal injury, those with obesity are more prone to positioning the lap belt superior to the ASIS, though the impact on abdominal injury incidence remains a key point for continued exploration into how occupant BMI affects crash safety and belt design.

Abstract
OBJECTIVE The effect of reclined seatbacks during frontal crashes in children seated on a belt-positioning booster (BPB) is not understood. Therefore, the aim of this study is to examine submarining in reclined child occupants with and without a BPB and with and without a simulated pre-pretensioner (PPT). We used the Large Omnidirectional Child (LODC) Anthropomorphic Test Device (ATD) seated on a production vehicle seat with and without a moderately reclined seatback angle during sled-simulated frontal vehicle crashes. METHODS Ten sled-simulated frontal impact tests were performed (24 g peak, 80 ms duration, 56 km/h delta-V). An adjustable D-ring anchor simulated a seat integrated belt. A fixed load-limited 3-point seatbelt webbing system was used to secure the LODC to a vehicle seat and booster seat. We compared the following conditions: a) BPB vs no-BPB and b) 25° versus 45° seatback angles, c) PPT, vs no-PPT in 45° seatback condition, each test was repeated. Abdominal forces (left and right), seatbelt loads, Anterior-Superior-Illiac-Spine forces (ASIS, upper and lower, left and right), and pelvis rotation were analyzed. RESULTS Average peak abdominal pressures were smaller in both nominal and moderate recline positions in the BPB (25°: 73.7 kPa, 45°: 82.5 kPa) compared to the no-BPB conditions (25°: 168.4 kPa, 45°: 339.1 kPa). In the 45° recline no-BPB conditions, both the peaks of the lap belt force and ASIS forces occurred early and a rapid reduction in those forces followed. This change in the lap belt and ASIS forces accompanied a rearward rotation of the pelvis. During the reduction of ASIS and lap belt forces, there was an increase in abdominal pressure suggesting that the lap belt moved upward, off the ASIS, and into the abdominal pressure sensor. There was a slight reduction in head and knee excursion with the PPT. These results suggest the presence of submarining in the 45° recline no-BPB conditions but not in the 45° recline with the BPB. CONCLUSIONS The BPB could be beneficial when the seatback is moderately reclined. The differences during the moderate recline between the BPB and no-BPB conditions also indicate that the BPB could prevent submarining in moderately reclined seats.

Abstract
BACKGROUND Thoracoabdominal injuries (TAI) are an important cause of trauma-related morbidity in children. Early and correct intervention is essential to reduce mortality. We aimed to determine factors associated with mortality and the need for intensive care in TAI. METHODS The children admitted to the pediatric emergency department of a tertiary care hospital with TAI in a 6-year-period were enrolled. Demographic data; mechanism of injuries; clinical, laboratory and imaging findings; length of hospital and intensive care unit (ICU) stay; invasive procedures and medical treatments; surgical interventions; and survival outcomes were recorded. RESULTS The median age of the 136 children was 9 (IQR: 5-14) years and 72.8% were male. The vast majority of injuries were caused by blunt trauma (92.7%). Pulmonary contusion, pneumothorax, splenic, and liver injuries were the most common diagnoses. Motor vehicle accidents were seen in more than half of the cases (52.2%). The median length of hospital stay was 5 (IQR: 2-8) days; 21 patients were hospitalized in the ICU (15.4%). The need for intensive care was higher in patients with lower Glasgow Coma Scale (GCS) scores and lower Pediatric Trauma Scores (PTSs), in the presence of multiple injuries, pulmonary contusion, and pneumothorax (p<0.001). Mortality was seen in nine patients, eight of whom had multiple injuries. The mortality rate was higher in patients with pulmonary contusion and pneumothorax (p=0.002 and p=0.003, respectively). The PTS and GCS were found to be lower in patients who died in hospital (p<0.001). Prolongation of coagulation parameters and hyperglycemia was more common in the non-survivor group (p=0.005 and p=0.004, respectively). CONCLUSION Although thoracoabdominal trauma is not common in childhood, it is an important part of trauma-associated mortality. Multiple injuries, pulmonary contusion, pneumothorax, lower GCS, and PTSs can be a sign of serious injuries to which physicians must be alert.

Abstract
BACKGROUND It is critical to accurately identify patients with abdominal injury who truly need to undergo laparotomy during the war in timely fashion. The diagnostic utility of computed tomography (CT) for evaluating abdominal injury in the military setting remains uncertain. METHODS PubMed, EMBASE, and Cochrane Library databases were searched. Meta-analyses were performed by using a random-effect model. We pooled the area under the summary receiver operating characteristic curves with standard errors, the Q indexes with standard errors, the sensitivities with 95% confidence intervals (CIs), the specificities with 95% CIs, the positive likelihood ratios with 95% CIs, the negative likelihood ratios with 95% CIs, and the diagnostic odds ratios with 95% CIs. The heterogeneity among studies were evaluated by the I2 and P value. RESULTS Overall, 5 retrospective studies were included. The area under the summary receiver operating characteristic curve was 0.9761 ± 0.0215 and the Q index was 0.9302 ± 0.0378. The pooled sensitivity was 0.97 (95% CI = 0.92-0.99) without a significant heterogeneity among studies (I2 = 0%, P = .4538). The pooled specificity was 0.95 (95% CI = 0.93-0.97) with a significant heterogeneity among studies (I2 = 90.6%, P < .0001). The pooled positive likelihood ratio was 10.71 (95% CI: 2.91-39.43) with a significant heterogeneity among studies (I2 = 89.2%, P < .0001). The pooled negative likelihood ratio was 0.07 (95% CI = 0.02-0.27) with a significant heterogeneity among studies (I2 = 57.5%, P = .0516). The pooled diagnostic odds ratio was 177.48 (95% CI = 18.09-1741.31) with a significant heterogeneity among studies (I2 = 75.9%, P = .0023). CONCLUSION Diagnostic accuracy of CT for abdominal injury is excellent in the military setting. Further work should explore how to shrink CT equipment for a wider use in wartime.

Abstract
OBJECTIVE Obesity has important implications for motor vehicle safety due to altered crash injury responses from increased mass and improper seatbelt placement. Abdominal seatbelt signs (ASBS) above the anterior superior iliac spine (ASIS) in motor vehicle crashes (MVCs) often correlate with abdominopelvic trauma. We investigated the relationship of body mass index (BMI), lap belt placement, and the incidence of abdominopelvic injury using computed tomography (CT) evaluation for subcutaneous ASBS mark and its location relative to the ASIS. METHODS A retrospective analysis of 235 Crash Injury Research and Engineering Network (CIREN) cases and their associated abdominal injuries was conducted. CT Scans were analyzed to visualize fat stranding. 150 positive ASBS were found and their ASBS mark location was classified as superior, on, or inferior to the ASIS. RESULTS Obese occupants had a higher incidence rate of belt placement superior to the ASIS, and occupants with normal BMI had a higher incidence of proper belt placement (p < 0.05). Trends of interest developed, notably that non-obese occupants with superior belt placement had increased incidence of internal abdominopelvic organ injury compared to those with proper belt placement (Normal BMI: 53.3% superior vs 39.4% On-ASIS, Overweight: 47.8% superior vs 34.7% On-ASIS). CONCLUSIONS Utilizing CT scans to confirm ASBS and lap belt placement relative to the ASIS, superior belt placement above the ASIS was associated with elevated BMI and a trend of increasing incidence of internal abdominopelvic organ injury.

Abstract
Introduction: The severity of injury from motor vehicle crashes (MVCs) depends on complex biomechanical factors, and the bodily features of the injured person account for some of these factors. By assuming that vulnerable road users (VRUs) have limited protection resulting from vehicles and safety equipment, the current study analyzed the characteristics of fat distribution measured by computed tomography (CT) imaging and investigated the existence of a "cushion effect" in VRUs. Materials and Methods: This retrospective study enrolled 592 VRUs involved in MVCs who underwent CT scans. Visceral fat area and subcutaneous fat cross-sectional area were measured and adjusted according to total body area (TBA) and are presented as the visceral fat ratio and the subQ fat ratio (subcutaneous fat ratio). Risk factors for serious abdominal injury (maximum abbreviated injury scale (MAISabd ≥ 3)) resulting from MVCs were determined by univariate and multivariate analysis. Results: MAISabd ≥ 3 was observed in 104 (17.6%) of the patients. The subQ fat ratio at the L4 vertebral level was significantly lower in the MAISabd ≥ 3 group than in the MAISabd < 3 group (24.9 ± 12.0 vs. 28.1 ± 11.9%; p = 0.015). A decreased L4 subQ fat ratio was associated with a higher risk for MAISabd ≥ 3 in multivariate analysis (odds ratio 0.063; 95% CI 0.008-0.509; p = 0.009). Conclusion: The current study supported the "cushion effect" theory, and protection was apparently provided by subcutaneous fat tissue. This concept may further improve vehicle and safety designation in the future.

Abstract
Penetrating abdominal injury is often a life-threatening condition, which is mainly associated with inflicted injuries. Fatal self-inflicted sharp force abdominal injuries too have been reported in the literature. Inadvertent penetrating abdominal injuries are a rarity and are caused by sharp objects of low-velocity and often nonmissile-type. A 27-year-old male factory worker was brought dead to the emergency department with an alleged history of sustaining abdominal injury by a sharp metal projectile while working on a metal cutting grinder. Autopsy observations were consistent with the history of inadvertent penetrating injury. Our case reports a fatal missile-type inadvertent sharp force trauma over the abdomen with intestinal perforation, a relatively uncommon scenario in occupational/workplace settings. The present case report describes the significance of the death scene visit and corroborating the medical findings with investigating agencies. This case further emphasizes on the need for adopting proper safety measures at the workplace.

Abstract
BACKGROUND Traumatic duodenal injuries in children are rare, and few studies have documented duodenal injuries in children, especially in Australasia. This study assessed the mechanism, investigations, management and outcomes of children (aged <16 years) with duodenal injuries. METHODS Retrospective review was conducted over a 16-year period from a single paediatric trauma centre. RESULTS Sixteen cases of duodenal injuries were identified: 15 cases of blunt duodenal injury and only one case of penetrating injury. Motor vehicular accidents were the most common cause of injury, followed by auto-pedestrian injuries and handlebar injuries. Only grade I and II injuries were identified. Computed tomography aided diagnosis in all cases of blunt duodenal injuries, especially given the variable nature of symptoms. Eight patients underwent laparotomy, of whom five required duodenal repair. Three patients underwent primary repair with omental patch, one patient underwent primary repair with gastrostomy and one patient underwent two-layered repair with t-tube duodenostomy. There were no delays in operative management within 24 h and no complications identified. CONCLUSION In comparison to other paediatric trauma centres worldwide, the majority of duodenal injuries were low grade and attributed to blunt trauma. Computed tomography aided diagnosis in all cases of blunt duodenal injury. Primary repair of duodenal injuries was possible in the majority of cases requiring operative repair.

Abstract
Traumatic abdominal wall herniation, especially of the groin region, is a rare condition and typically results from a high-energy trauma to the abdominal wall. We report a fatal case of a road-traffic collision involving a young male motorcyclist who collided with a speeding lorry. The victim sustained multiple injuries over the chest and abdomen, with traumatic inguinal herniation causing gross distension of the scrotum. At autopsy, multiple lacerations of thoracic and abdominal organs were seen, along with traumatic disruption of the right inguinal canal. The contused terminal ileum was present in the scrotal sac. A literature search has revealed a limited number of reported cases of gross inguinal herniation following thoracoabdominal trauma. In cases of high-energy trauma to the thoraco-abdominal region with unilateral or bilateral distension of the scrotum, the possibility of herniation of the abdominal contents into the scrotal sac should be considered by the forensic pathologist.

Abstract
Resuscitative endovascular balloon occlusion of the aorta has increasingly been used all the world over for arresting ongoing intraabdominal and intrapelvic bleeding accompanied by unstable haemodynamics. However, the use of resuscitative endovascular balloon occlusion of the aorta in a zone of military operations has been limited to sporadic cases only. This article deals with 3 clinical case reports regarding rendering medical care for the wounded presenting with extremely unstable haemodynamics and/or a terminal state in a field hospital, where insertion of a balloon into the aorta made it possible to stabilize the condition, to perform the basic scope of diagnosis, and to finally control the continuing bleeding: in one case - intraabdominal (due to splenic rupture) and in 2 cases - intrapelvic (unstable fractures of pelvic bones). In two cases, despite low readings of blood pressure, puncture of the femoral artery was performed 'blindly' and in one case - in an open fashion. The balloons used were the 7 Fr Rescue Balloon (Japan) and 10 Fr balloons manufactured by the Limited Liability Company 'Minimally Invasive Technologies' (Russia). The balloons were positioned in the aorta also 'blindly' and only in one case we managed to perform an X-ray examination confirming the correct position of the balloon. The mean time of occlusion of the thoracic aorta in the survivors amounted to 20 minutes. The operations were accompanied by intensive therapy and massive haemotransfusion. The introducers were removed using the fascia suture technique (without closure of the arterial wall). Two of the three wounded were saved, to be evacuated to a central hospital and discharged 170 and 75 days thereafter, which was due to long-term treatment of severe concomitant fractures of pelvic bones and lower extremities. No complications on the background of resuscitative endovascular balloon occlusion of the aorta were revealed. Two years after surgery both men continue serving in the Armed Forces, with no significant functional impairments. Our third injured patient delivered in a condition of clinical death, despite restoration of the rhythm after inflation of the balloon unfortunately died. Our case reports demonstrate high efficacy of resuscitative endovascular balloon occlusion of the aorta in unstable haemodynamics induced by combat injury to the abdomen and pelvis. The technique of this method makes it possible not only to stabilize haemodynamics, to improve perfusion of the vital organs but also to staunch continuing haemorrhage, hence allowing additional time to carry out haemotransfusion. In future, resuscitative endovascular balloon occlusion of the aorta may become one of the methods of the extended protocol of prehospital care.

Abstract
INTRODUCTION Multitrauma is defined as injury involving two or more different body parts, with a condition that at least one of these injuries is life-threatening. They represent serious traumas, requiring treatment in the intensive care units and frequently surgical intervention. AIM The objective of this study was epidemiological and clinical analysis of patients treated in 2015 year in Multitrauma Centre of the University Teaching Hospital no 1 in Szczecin, and comparison the results with outcomes of similar study conducted in the same Centre in 2007 year. MATERIAL Clinical material comprised medical notes of 82 patients, 52 men (63%) and 30 women (37%), with a mean age of 44 years, who sustained multitrauma injuries. An analysis included causes of traumas, spectrum of injuries, involvement of body parts, methods and outcomes of the treatment. RESULTS The most common cause of multitrauma was traffic accident - 45 cases (55%), followed by fall from height - 22 (27%) and other mechanism - 15 (18%). The most frequent component of multitrauma made bone fractures (spine, pelvis, limbs) - 64 cases (78%), followed by head traumas - 63 (77%), chest - 53 (65%) and abdominal 30 (36%) injuries. A total of 48 patients (58%) required surgical intervention, the most frequently fixation of bone fractures - 24 patients (29%), repair of abdominal and head injuries - 18 (22%) either. Of 82 treated patients 64 (78%) survived and 18 (22%) died. A mean period of stay in Multitrauma Centre was 23 days for survived patients and 17 days for those who died. Comparing to similar analysis conducted 8 years earlier, a change in involvement of particular body parts comprising multitrauma injury was observed: number of head injuries increased of 14%, number of chest traumas and bone fractures decreased of 21% and 11%, respectively. The survival rate improved of 10%.

Abstract
Benign paroxysmal positional vertigo (BPPV) is a comorbid condition prevalent in patients recovering from trauma. Due to the paucity of studies investigating the etiology of this condition, the present study sought to analyze the high-risk group of BPPV patients following trauma.Trauma patients visiting the emergency department from January to December 2016 were enrolled. The study excluded patients with minor superficial injuries, those who were dead, and those discharged within 2 days after their visit. The medical records were reviewed, and every abbreviated injury score, injury severity score, and other clinical characteristics, such as age and sex, were gathered. A diagnosis of BPPV was reached only after a provocation test was administered by an otolaryngologist. The correlation was statistically analyzed.A total of 2219 trauma patients were analyzed. The mean age of the patients was 52.6 years, and the mean injury severity score (ISS) was 7.9. About 70% of the patients were men. Additional BPPV patients were identified among patients with injuries to head and neck, chest, and abdomen, and those with external injuries. However, patients with head and neck (odds ratio [OR] (95% confidence interval [CI]) = 10.556 (1.029-108.262), and abdominal injury (OR [95% CI] = 78.576 [1.263-4888.523]) showed statistically significant correlation with BPPV in the logistic regression analysis. Patients-not only those with head and neck injuries but those with abdominal injuries-who complain of dizziness need to be evaluated for BPPV using provocation tests. Further studies investigating traumatic BPPV are needed.

Abstract
Introduction Abdominal injuries are responsible for 10% of the mortalities due to trauma. Delays in early diagnosis or misdiagnoses are two major reasons for the mortality and morbidity associated with abdominal trauma. The objectives of this study were to determine the frequency of visceral injuries in patients with abdominal trauma and compare the frequency of visceral injuries in patients with blunt and penetrating abdominal trauma. Methods We conducted a cross-sectional study from May 2016 to May 2018 of patients presenting to the emergency department (ED) at Jinnah Postgraduate Medical Center in Karachi, Pakistan. Patients were 12 to 65 years old and presented within 24 hours of abdominal trauma. We recorded the type of abdominal visceral injuries, such as liver, spleen, intestine, stomach, mesentery, and pancreas. Results The mean patient age was 31 ±13 years. Penetrating trauma was found in most patients (n=72, 51%). Liver injuries were found in 37 patients (26.4%), spleen injuries in 29 patient (20.7%), stomach injuries in eight patients (5.7%), intestine injuries in 67 patients (47.9%), mesentery injuries in 21 patients (15%), and pancreas injuries in nine patients (6.4%). The type of abdominal trauma was found significantly associated with liver injury (p-value 0.021), and intestine injury (p-value <0.001). Conclusion Penetrating trauma (51.4%) was more common than blunt trauma (48.5%), and intestines are the most commonly affected by penetrating and blunt trauma injuries (70.1% and 47.8%, respectively). The liver is the most commonly affected (42.85%) in blunt trauma injuries, followed by the spleen (28.5%). The appropriate authorities should consider this information when instituting public health and safety initiatives.

Abstract
Background: In trauma patients, pancreatic injury is rare; however, if undiagnosed, it is associated with high morbidity and mortality rates. Few predictive models are available for the identification of pancreatic injury in trauma patients with elevated serum pancreatic enzymes. In this study, we aimed to construct a model for predicting pancreatic injury using a decision tree (DT) algorithm, along with data obtained from a population-based trauma registry in a Level I trauma center. Methods: A total of 991 patients with elevated serum levels of amylase (>137 U/L) or lipase (>51 U/L), including 46 patients with pancreatic injury and 865 without pancreatic injury between January 2009 and December 2016, were allocated in a ratio of 7:3 to training (n = 642) or test (n = 269) sets. Using the data on patient and injury characteristics as well as laboratory data, the DT algorithm with Classification and Regression Tree (CART) analysis was performed based on the Gini impurity index, using the rpart function in the rpart package in R. Results: Among the trauma patients with elevated amylase or lipase levels, three groups of patients were identified as having a high risk of pancreatic injury, using the DT model. These included (1) 69% of the patients with lipase level ≥306 U/L; (2) 79% of the patients with lipase level between 154 U/L and 305 U/L and shock index (SI) ≥ 0.72; and (3) 80% of the patients with lipase level <154 U/L with abdomen injury, glucose level <158 mg/dL, amylase level <90 U/L, and neutrophil percentage ≥76%; they had all sustained pancreatic injury. With all variables in the model, the DT achieved an accuracy of 97.9% (sensitivity of 91.4% and specificity of 98.3%) for the training set. In the test set, the DT achieved an accuracy of 93.3%, sensitivity of 72.7%, and specificity of 94.2%. Conclusions: We established a DT model using lipase, SI, and additional conditions (injury to the abdomen, glucose level <158 mg/dL, amylase level <90 U/L, and neutrophils ≥76%) as important nodes to predict three groups of patients with a high risk of pancreatic injury. The proposed decision-making algorithm may help in identifying pancreatic injury among trauma patients with elevated serum amylase or lipase levels.

Abstract
BACKGROUND Lower rib fractures are considered as a marker of intra-abdominal organ injury. Abdominal computed tomography (CT) is the "gold standard" examination for patients with lower rib fractures. However, the reported incidence of concomitant intra-abdominal injuries (IAI) is 20%-40%. OBJECTIVE The purpose of this study was to evaluate the incidence of intra-abdominal organ injuries in blunt trauma patients with lower rib fractures. METHODS Medical charts and radiology reports of patients with lower rib (from the 8th to 12th rib) fractures admitted to our center during a 6-year period were retrospectively reviewed. Patients were divided into two groups. Group I included patients with intra-abdominal injury (IAI) diagnosed either by CT or on urgent laparotomy, and Group II included those with normal abdominal CT scans. Data included demographics, mechanism of injury, laboratory tests, radiology results including number and location of fractured ribs, and incidence of IAI. RESULTS Overall 318 patients were included in the study. Fifty-seven patients (17.9%) had 71 IAIs compared with 265 (82.1%) patients with no IAI. Logistic regression identified age younger than 55 years (relative risk [RR] = 7.2; 95% confidence interval [CI] 3.1-16.8; p = 0.001), bilateral rib fractures (RR = 3.9; 95% CI 1.1-13.5; p = 0.03) and decreased levels of hematocrit (RR = 2.4; 95% CI 1.2-4.8; p = 0.016) as independent risk factors for the presence of IAI. CONCLUSIONS Abdominal CT should be considered in blunt trauma patients with lower rib fractures who are younger than 55 years of age and have bilateral rib fractures and decreased levels of hematocrit on admission.

Abstract
OBJECTIVES Due to limitations of classic imaging approaches, the internal response of abdominal organs is difficult to observe during an impact. Within the context of impact biomechanics for the protection of the occupant of transports, this could be an issue for human model validation and injury prediction. METHODS In the current study, a previously developed technique (ultrafast ultrasound imaging) was used as the basis to develop a protocol to observe the internal response of abdominal organs in situ at high imaging rates. The protocol was applied to 3 postmortem human surrogates to observe the liver and the colon during impacts delivered to the abdomen. RESULTS The results show the sensitivity of the liver motion to the impact location. Compression of the colon was also quantified and compared to the abdominal compression. CONCLUSIONS These results illustrate the feasibility of the approach. Further tests and comparisons with simulations are under preparation.

Abstract
BACKGROUND Abdominal trauma secondary to non-accidental injury is associated with high rates of morbidity and mortality. It has been noted that children who have suffered abusive abdominal injuries often lack abdominal wall bruising. We hypothesize that children have highly elastic vessels that stretch instead of rupturing when the abdomen is punched. Our study investigates the degree of elasticity in abdominal wall vessels in young children. METHODS Twenty children aged less than 5 years undergoing routine hernia repair or orchidopexy were included in our study. Subcutaneous vessels were identified during the procedures. The vessels were measured at resting length and when stretched to maximum length prior to rupture. Samples of the vessels were then collected for histological examination. RESULTS On average, we were able to stretch the vessels to 3.4 times their resting length without rupture. Histology revealed that the vessel walls contained a high amount of elastin. CONCLUSION We have demonstrated a high degree of elasticity in the abdominal wall vessels of young children. This may help to explain why children do not bruise when hit in the abdomen. Our findings have potential implications for both clinical practitioners and paediatric surgeons involved in child abuse cases.

Abstract
OBJECTIVE Pretensioners reduce the seat belt slack and couple the occupant early to the restraint system. There is a growing prevalence of rear seat pretensioners and it is essential to determine whether the load from the pretensioner itself can cause injuries to rear-seated children. The aim of the study was to investigate the loading to the neck, chest, and abdomen of various sizes of anthropometric test devices (ATDs) during the pretensioner deployment phase and the crash phase in low-severity frontal sled tests and during static deployment. METHODS Low-severity frontal sled tests were conducted with the Hybrid III (HIII) 3-year-old, HIII 6-year-old, HIII 5th percentile, and HIII 50th percentile ATDs. Two different retractor pretensioners with varying pretensioner force were used. The child ATDs were restrained on a booster cushion (BC), with and without a back. The loading to the neck and chest was compared to injury assessment reference values (IARVs) reported by Mertz et al. (2003). The chest loading to the HIII 5th percentile and HIII 50th percentile ATDs was also analyzed using age-related injury risk curves. Static pretensioner tests with the Q-series 10-year-old ATD, equipped with an advanced abdominal loading device, were conducted in standard ATD position and out-of-position with the lap belt positioned high on the abdomen. RESULTS During the crash phase, head excursion and neck loading were reduced for both pretensioners for all ATDs compared to testing without a pretensioner. The pretensioner reduced chest deflection to the adult ATDs but not to child ATDs when seated on a BC with a back during the crash phase. When the back was removed, chest deflection was reduced below IARV. The head excursion was reduced for all ATDs with both pretensioners. During the pretensioner deployment phase, the chest deflection exceeded the IARV for the HIII 3-year-old with the stronger pretensioner when seated on booster with a back and it was reduced below the IARV with the lower force pretensioner. For all ATDs, neck and chest loading during the pretensioner deployment phase were reduced when a pretensioner with lower force was used. Abdominal loading to the Q10 in the static pretensioner deployments indicated a low risk of abdominal injury in all tested positions. CONCLUSION This study indicates the need to balance the pretensioner force and seat belt geometry to gain good pretensioner performance in both the pretensioner deployment phase and the crash phase.

Abstract
Background: Characteristics of extracranial injury in patients with diffuse axonal injury (DAI) have not been clarified. Materials and Methods: This retrospective study reviewed medical records from January 2003 to December 2007. Subjects comprised 35 patients meeting the following criteria: 1) head injury without mass lesion; 2) Glasgow coma scale (GCS) on arrival <15; and 3) magnetic resonance imaging (MRI) examination including T2*-weighted imaging. Subjects were divided into two groups: severe traumatic brain injury (TBI) group (patients with GCS ≤8, n=19) and moderate TBI group (patients with GCS >8, n=16). Results: Shock index (heart rate/systolic blood pressure) was significantly higher in the severe TBI group than in the moderate TBI group, while base excess on arrival was significantly lower in the severe TBI group than in the moderate TBI group. The abbreviated injury scale (AIS) for the face, thorax, extremities and external structures showed no significant differences between the severe TBI group, but AIS for the abdomen and the sum of extracranial AIS was greater in the severe TBI group than in the moderate TBI group. Duration of hospitalization was longer and outcomes were worse in the severe TBI group than in the moderate TBI group. Conclusion: Because patients with severe TBI are more likely to have abdominal injury than patients with moderate TBI, physicians should be aware of the potential for such complications when treating severe TBI.
