Introduction: Horseback riding can cause severe brain and spinal injuries. This study aimed to identify the spectrum of neurosurgical injuries related to recreational horseback riding., Methods: A retrospective study was performed utilizing the University of Puerto Rico neurosurgery database to identify patients who were consulted to the neurosurgery service between 2018 and 2023 after a horse fall during recreational activities. The outcome upon discharge using the modified Rankin scale (mRS) was documented. Descriptive statistics were used to report frequency and median values., Results: The neurosurgery service evaluated and managed 112 patients with a horseback riding fall-related injury during 6 years. Ninety-eight (87.5%) patients were male. The patients' median age was 31.5 (IQR 22-40). There were 89 head injuries (79.5%), 19 spinal injuries (17%), and 4 combined head/spine injuries (3.5%). Forty percent of the patients were admitted to inpatient care with a median length of stay of 7 days (IQR 3-17). Twenty-four patients (21%) required surgery. Upon discharge, 86.6% of the patients had an mRS grade of 0-2, 3.6% had a grade of 3, 1.8% had a grade of 4, and 1.8% had a grade of 5. Seven patients (6%) died (mRS grade 6)., Conclusions: Most neurologic injuries involve isolated trauma to the head. Fifteen percent of the riders' falls were caused after the horse was impacted by a motor vehicle. Forty percent of the patients require admission and 21% undergo surgery. Ten percent of the patients had a poor mRS grade of 4- to 6 when discharged., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Introduction Imaging experience made us suspect an overrepresentation of ponytails in riders admitted as polytrauma after falling from their horse. Methods In a single-centre case-control study conducted over three months, we reviewed the records of all admitted polytraumatised patients for trauma mechanism and presence of ponytail on CT. Cerebral CTs were reviewed in the three standard imaging planes using a bone or lung window. Ponytail was diagnosed if most or all of the hair on the head was gathered and secured at the back of the head with a hair tie. Data were analysed with Fisher's exact test. Results Seven female riders (mean age 22 years) were admitted after falling from their horse (study group); six of these riders wore a ponytail. No male riders were admitted. Therefore, only female polytraumatised patients having suffered any other trauma were selected as controls. The control group consisted of 13 patients (mean age 33,5 years), two of whom wore a ponytail. In three controls, all without ponytails, the trauma also had been related to a horse. Thus, horses were involved in 50% of the traumas included in this study. Ponytail was found more frequently in riders admitted after falling from their horse, p less-than 0,005. Conclusion Having an almost circumferential vision, horses may be scared by the sideways swaying of a ponytail worn by their own rider. In riders, ponytails can trigger a sensation of tightness or even headache which may impair focus. Thus, while female riders most likely wear ponytails for practicality, ponytails may increase the risk of accident by affecting rider and horse. Further studies are required to determine if the observed association between ponytails and trauma is causal. Funding none.

The purpose of this study was to identify surgical complications after distal humerus fracture fixation as well as correlations between these complications and patient variables. A total of 132 patients underwent open reduction and internal fixation of traumatic distal humerus fractures between October 2011 and June 2018. Included were adult patients who underwent surgical fixation and had more than 6 months of follow-up. Excluded were patients with inadequate radiographic imaging, less than 6 months of follow-up, and previous distal humerus surgery. Multivariate logistic regression models controlling for age and body mass index were used to determine preoperative factors predictive of postoperative complications. A total of 73 patients were included in this analysis. Surgical complications were reported for 17 patients. Reoperation was required for 13 patients. Open injury at presentation was predictive of delayed union. Predictors of subsequent elbow surgery included younger age, polytrauma, open fracture, and ulnar nerve injury at the time of injury. Radial nerve injury at the time of presentation was also a risk factor for postoperative radial nerve symptoms. Predictors of postoperative heterotopic ossification included older age. Thirty-one patients had an olecranon osteotomy during their open reduction and internal fixation and none went on to nonunion. There were 13 patients with ulnar nerve complications. Of these patients, 3 had undergone an ulnar nerve transposition. None of the other studied variables were predictors of complications, malunion, or nonunion at latest follow-up. Although open reduction and internal fixation is effective in treating distal humerus fractures, its complications cannot be overlooked. Open fractures are more likely to go on to delayed union. Ulnar nerve injury, open fracture, and polytrauma were predictive for reoperation. Older patients were less likely to have subsequent surgery but more likely to develop heterotopic ossification. By identifying at-risk patients, managing physicians can better prognosticate and counsel patients on their recovery. [ Orthopedics . 2023;46(6):352-357.].

Background and Objectives : The primary objective of this study was to obtain quantitative data, taking into account the amount of radiation exposure, about the clinical and diagnostic benefit obtained from panCT in pediatric trauma cases. Thus, we aim to create greater awareness in all physicians and primarily emergency medicine physicians regarding correct selection in terms of the patient group where this effective radiological method is to be applied, and to protect children from the adverse effects of radiation. Materials and Methods : The computed tomography (CT) images were retrieved from the hospital radiological archive system (PACS). The effective dose (Ed) was calculated using the standardized method including the tissue weighted parameters. The radiological pathologies determined as a result of CT imaging of the cases were categorized according to clinical significance in accordance with the Modified CT Colonography Reporting and Data System (C-RADS). Results : The data for a total of 268 patients were analyzed, comprising 89 (33.2%) females and 179 (66.8%) males with a mean age of 8.81 ± 5.21 years. The mean Ed was determined to be 18.14 ± 10.44 mSv. The Ed was determined to be statistically significantly higher in the 1-5 years age group than in the 15-18 years age group ( p = 0.024). A statistically significant difference was determined between the age groups in terms of the pathologies determined ( p = 0.028). Conclusions : In order to prevent performing unnecessary CT imaging, trauma teams in Emergency Departments (ED) should work in harmony and individual decision-making should be based on the severity of the trauma mechanism, the severity of the predicted injury, and the clinical status of the injured child.

Background: Surgical fixation of humeral shaft fractures is widely considered a relative indication for polytraumatized patients to improve mobility and expedite care. This study aimed to determine whether operative treatment of humeral shaft fractures improves short term outcomes in polytrauma (PT] patients., Methods: Using the National Trauma Data Bank, PT patients with humeral shaft fractures were identified from 2010-2015. Three PT groups were analyzed: Group 1 - PT with nonoperative humeral shaft fracture, Group 2 - PT with humeral fixation on Day 1, and Group 3 - PT with humeral fixation on Day 2+. Cox proportional hazards regression models were used to compare discharge timing and days on ventilator and in ICU between the three groups., Results: There were 395 patients in Group 1, 1,346 in Group 2, and 1,318 in Group 3. There were no differences between the three groups when comparing Glasgow Coma Scale (p=0.3]; however, Injury Severity Score and Abbreviated Injury Scale were statistically different (p<0.001]. No differences were found in ICU or ventilator days between the three groups (p=0.2, p=0.5]. For Length of Stay, no difference was observed in Group 1 vs. Group 2 and Group 2 vs. Group 3. However, non-surgical patients were discharged 20% faster than those with Day 1 surgery (p=0.005]. Open fractures were treated one day earlier than closed fractures but discharged one day later (p<0.001]., Conclusions: This NTDB study demonstrates no differences in length of stay, days in the ICU or on the ventilator in patients with humeral shaft fractures treated non-operatively versus operative fixation. Overall, 44%-58% in all 3 groups had an ISS ≥ 14. Based on these results, we assert that fixation of the humeral shaft provides no short-term benefits in the multiply injured patient., Competing Interests: Declarations of interest None., (Copyright © 2022.

Terrorism-related injuries and deaths have become a major threat to the Somalian population, as in the rest of the world. We aimed to characterize and compare firearm and explosion injuries caused by terrorist acts. This retrospective study reviewed the data of all patients injured by explosions and firearm attacks over seven years. Epidemiological characteristics, injury pattern, severity scores, hospital resource utilization parameters, length of stay, and death rates were evaluated. A total of 2426 patients were injured by 359 explosions and firearm attacks during the study period. Eighty-one percent of the patients (n = 1974) were male, while 19% of the cases were female. Multiple body site injuries occurred more frequently in explosion injuries (75%) than firearm wounds (48%) (P < 0.001). The relative frequency of internal injuries in explosion injuries was higher than in firearm wounds (46.7% vs. 36.2%). Patients injured due to the explosion have a greater rate of severe and critical injuries than those injured by firearms (30.2% vs. 21.2%, P < 0.001). About a quarter (24%) of the patients were hospitalized in the intensive care unit. The inpatient mortality rate was 11.6%. The findings of the study revealed that suicide bombings explosions are associated with multiple body site injuries, a greater rate of severe and critical internal injuries, and a higher mortality rate., (© 2022.

Background: In 2016 the first German recommendation for the preclinical use of tourniquets was published. Currently little is known of the frequency of the use of tourniquets in the prehospital setting in Germany. This study evaluated how often a tourniquet is used in a civilian German Helicopter Emergency Medical Service (HEMS)., Method: After the approval of the scientific working group of the DRF Luftrettung HEMS, the electronic database (HEMSDER) of the DRF Luftrettung HEMS was analyzed for the period 2015-2020 under the abovementioned question. All patients with a tourniquet application were included in the study and a comparison was made with the total trauma cohort and a subgroup analysis between patients who additionally required airway management and patients without additional airway management in the cohort of tourniquet patients. The analysis was mainly descriptive. Parametric test (t-tests and χ 2 -tests) were used for group comparison., Results: During the study period 67,321 trauma patients were treated and in 866 (1.3% of all trauma patients) a tourniquet was used. The mean age of these patients was 45.9 years (±19.5 years), 710 (84%) were male, 439 (51%) suffered a monotrauma, 296 (34%) suffered multiple trauma, 339 (38%) required a prehospital airway management and 321 (37%) of these were intubated. Significant differences between patients with tourniquet application and the rest of the trauma cohort were detected in general data (monotrauma, polytrauma and high-speed trauma, massive bleeding), vital signs at the scene of the accident (GCS, HF, S p O 2 ) and necessary interventions, such as pressure bandages and use of hemostyptics, tranexamic acid, analgesia, the frequency of intubation and colloidal volume replacement. Due to limitations of the data set we could not obtain information regarding the limb used for the tourniquet, whether a conversion of the tourniquet was carried out and if the tourniquet was used according to the current German trauma guidelines., Conclusion: With a frequency of 1.3% the need for a prehospital tourniquet application is low in civilian trauma patients. Monotrauma with isolated extremity injuries represent about half of the patients treated with tourniquets. The other half is represented by multiple injuries or multiple trauma patients who require significantly more invasive measures, such as airway management and more complex on-scene interventions are needed. The available data do not allow any conclusions to be drawn about the location and the quality of the tourniquet application. Future documentation systems should incorporate data on the use of tourniquets, such as the location of use, indications (tactical use/massive bleeding), bleeding control achieved (yes/no) or second tourniquet necessary, conversion (yes/no) and any obvious complications., (© 2021.

A major public health problem, polytrauma is the leading cause of death in the 15-35 age group, 50% of which occurs within the first hour. This is why the initial care of these patients and their rapid referral to a specialized center (trauma center) is so important. The nurse is in the front line of the care system, in tandem with the medical team., (Copyright © 2021 Elsevier Masson SAS. All rights reserved.)

We report the case of a patient with injuries to multiple organs as a result of attempted suicide with a nail gun. The patient shot 12 nails into his chest, causing damage to multiple organs, including the heart, lungs, and stomach. With timely emergency surgery, we successfully removed all the nails, and the patient was discharged from the hospital two weeks after surgery.

Traumatic brain injury (TBI) is a leading cause of death and disability. Epidemiology seems to be changing. TBIs are increasingly caused by falls amongst elderly, whilst we see less polytrauma due to road traffic accidents (RTA). Data on epidemiology is essential to target prevention strategies. A nationwide retrospective cohort study was conducted. The Dutch National Trauma Database was used to identify all patients over 17 years old who were admitted to a hospital with moderate and severe TBI (AIS ≥ 3) in the Netherlands from January 2015 until December 2017. Subgroup analyses were done for the elderly and polytrauma patients. 12,295 patients were included in this study. The incidence of moderate and severe TBI was 30/100.000 person-years, 13% of whom died. Median age was 65 years and falls were the most common trauma mechanism, followed by RTAs. Amongst elderly, RTAs consisted mostly of bicycle accidents. Mortality rates were higher for elderly (18%) and polytrauma patients (24%). In this national database more elderly patients who most often sustained the injury due to a fall or an RTA were seen. Bicycle accidents were very frequent, suggesting prevention could be an important aspect in order to decrease morbidity and mortality., (© 2021. The Author(s).)

Severe injuries are frequently accompanied by hemorrhagic shock and harbor an increased risk for complications. Local or systemic inflammation after trauma/hemorrhage may lead to a leaky intestinal epithelial barrier and subsequent translocation of gut microbiota, potentially worsening outcomes. To evaluate the extent with which trauma affects the gut microbiota composition, we performed a post hoc analysis of a murine model of polytrauma and hemorrhage. Four hours after injury, organs and plasma samples were collected, and the diversity and composition of the cecal microbiome were evaluated using 16S rRNA gene sequencing. Although cecal microbial alpha diversity and microbial community composition were not found to be different between experimental groups, norepinephrine support in shock animals resulted in increased alpha diversity, as indicated by higher numbers of distinct microbial features. We observed that the concentrations of proinflammatory mediators in plasma and intestinal tissue were associated with measures of microbial alpha and beta diversity and the presence of specific microbial drivers of inflammation, suggesting that the composition of the gut microbiome at the time of trauma, or shortly after trauma exposure, may play an important role in determining physiological outcomes. In conclusion, we found associations between measures of gut microbial alpha and beta diversity and the severity of systemic and local gut inflammation. Furthermore, our data suggest that four hours following injury is too early for development of global changes in the alpha diversity or community composition of the intestinal microbiome. Future investigations with increased temporal-spatial resolution are needed in order to fully elucidate the effects of trauma and shock on the gut microbiome, biological signatures of inflammation, and proximal and distal outcomes.

Abstract: Camels are ungulates of the genus Camelus and have been used for centuries in parts of Asia and Africa for transport and sustenance. Handling of camels is not without its dangers, and 4 cases from South Australia are reported with a review of lethal camel-related issues. Case 1 is a 56-year-old man who died of multiple blunt force injuries after he had attempted to move a 7-year-old female dromedary (Camelus dromedarius). Case 2 is a 65-year-old woman who was crushed by 1 or more camels that she had been training. Case 3 is a 1-year-old girl who died of blunt craniocerebral trauma after the car in which she was traveling rolled when the driver swerved to avoid a herd of camels that had strayed onto the road. Case 4 is a 66-year-old woman who died of ischemic and hypertensive cardiac disease exacerbated by physical activity while rounding up camels. Deaths associated with camels involve kicking, stomping, kneeling or sitting on a victim, or biting and shaking and throwing. Lethal mechanisms include hemorrhage from vascular injuries and internal organ disruption, crush asphyxia, and blunt craniospinal injuries. Death may also follow falls from camels or vehicle collisions. Camels also carry a wide range of zoonotic diseases, the most significant of which is Middle Eastern respiratory syndrome. Handling of camels may also exacerbate underlying organic illnesses such as cardiac disease. Those working with camels should be aware that the size, strength, and temperament of these animals may make them dangerous and that they also carry potentially lethal zoonotic diseases., Competing Interests: The authors report no conflict of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Introduction: Firearm-related spinal cord injuries are commonly missed in the initial assessment as they are often obscured by concomitant injuries and emergent trauma management. These injuries, however, have a significant health and financial impact. The objective of this study was to examine firearm-related spinal cord injuries and identify predictors of presence of such injuries in adult trauma patients., Methods: This retrospective cohort study examined adult trauma patients (≥16 years) with injuries from firearms included in the 2015 United States National Trauma Data Bank. We performed descriptive and bivariate analyses and compared two groups: patients with no spinal cord injury (SCI) or vertebral column injury (VCI); and patients with SCI and/or VCI. Predictors of SCI and/or VCI in patients with firearm-related injuries were identified using a multivariate logistic regression analysis., Results: There were 34,898 patients who sustained a firearm-induced injury. SCI and/or VCI were present in 2768 (7.9%) patients. Patients with SCI and/or VCI had more frequently severe injuries, higher Injury Severity Score (ISS), lower mean systolic blood pressure, and lower Glasgow Coma Scale (GCS). The mortality rate was not significantly different between the two groups (14.7%, N = 407 in SCI and/or VCI vs 15.0%, N = 4,811 in no SCI or VCI group). Significant general positive predictors of presence of SCI and/or VCI were as follows: university hospital; assault; public or unspecified location of injury; drug use; air medical transport; and Medicaid coverage. Significant clinical positive predictors included fractures, torso injuries, blood vessel or internal organ injuries, open wounds, mild (13-15) and moderate GCS scores (9 - 12), and ISS ≥ 16., Conclusion: Firearm-induced SCI and/or VCI injuries have a high burden on affected victims. The identified predictors for the presence of SCI and/or VCI injuries can help with early detection, avoiding management delays, and improving outcomes. Further studies defining the impact of each predictor are needed.

Background: The present study aims to assess whether there are any differences in the management and outcome of polytrauma patients with thoracic trauma in trauma units of two different hospitals in the same country; one hospital is near the Syrian border., Methods: A retrospective analysis (January 2012 to January 2014) of 348 polytrauma casualties with thoracic trauma from Manisa Celal Bayar University Hospital (MH) were compared according to age, gender, mechanism of injury, associated injuries, abbreviated injury scale (AIS), injury severity score (ISS), treatment modalities, and mortality with 917 patients of Şanlıurfa Training and Research Hospital (SH) registry (near the Syrian border)., Results: Of the 348 patients in the MH, 230 (66%) and of the 917 patients in the SH, 697 (76%) were males (p<0.001). Mean age was 45.6±18.3 yrs in the MH group and 26.4±22.4 yrs in the SH group (p<0.001). The SH patients had a larger proportion of stab wounds (MH; 9% vs. SH; 17%, p<0.05), gunshot injuries (MH; 5% vs. SH; 18%, p<0.05), higher mean ISS (MH; 30.2±8.4 vs. SH; 42.8±10.2, p<0.001), and increased mortality (MH; 2.6% vs. SH; 11.1%, p<0.001). AISabdomen was the highest component in the SH registry (AISabdomen = 4.8±0.7), whereas AIS extremities were the highest component in the MH registry (AISextremities = 3.6±0.2)., Conclusion: Significantly different demographic features, mechanisms of injury, worse outcomes and higher mortality rates in SH demonstrate and reflect the surgical challenges depending on the combat environment. Two hospitals in Turkey, one seemingly adjacent to a war zone and another with the more standard civilian experience highlight the impact of the Syrian conflict on the Turkish healthcare system.

Introduction: Pelvic ballistic injuries threaten critical gastrointestinal, vascular, and urinary structures. We report the treatment patterns and injury profiles of ballistic pelvic fractures and the association between location of ballistic fractures of the pelvis and visceral injuries., Methods: A prospectively collected database at an academic level I trauma center was reviewed for clinical and radiographic data on patients who sustained one or more ballistic fractures of the pelvis. Main outcomes compared included: procedures with orthopedic surgery, emergent surgery, concomitant intrapelvic injuries, and mortality., Results: Eighty-six patients were included. Eight patients (9.3%) underwent surgical debridement with orthopedic surgery, no ballistic pelvic fractures required surgical stabilization. The anatomical locations of ballistic pelvic fractures included: 10 (14.7%) anterior ring, 13 (19.1%) posterior ring, 27 (39.7%) anterior column, and 18 (20.9%) posterior column. There was a statistically significant association between anterior ring and rectal injury. The association between anterior ring injury and bladder injury approached significance., Conclusions: This case series included 86 patients with a ballistic fracture of the pelvis, none requiring pelvic ring surgical stabilization. The unpatterned behavior of these injuries demands a high suspicion for visceral injury, with special attention to the rectum and bladder in the setting of anterior ring involvement., Level of Evidence: IV.

Lethal injuries due to large animal attack are uncommon in routine forensic practice in Europe. Specifically, few incidents are reported concerning tiger/lion attacks that usually involve captive circus or zoo animals. We present the case of a 61-year old animal tamer who was mauled to death by four tigers while he was training them for a circus performance. Careful investigation of the circumstances surrounding the fatality revealed that the tamer had most likely been struck with a tiger paw and then mauled by additional tigers resulting in serious and fatal injuries. Although a full medico-legal autopsy was not authorized, total body CT scan coupled with post-mortem external examination allowed a reconstruction of events.

Multiple injuries appear to be a decisive factor for experimental polytrauma. Therefore, our aim was to compare the inflammatory response and organ damage of five different monotrauma with three multiple trauma models. For this, mice were randomly assigned to 10 groups: Healthy control (Ctrl), Sham, hemorrhagic shock (HS), thoracic trauma (TxT), osteotomy with external fixation (Fx), bilateral soft tissue trauma (bsTT) or laparotomy (Lap); polytrauma I (PT I, TxT + HS + Fx), PT II (TxT + HS + Fx + Lap) and one multi-trauma group (MT, TxT + HS + bsTT + Lap). The inflammatory response and organ damage were quantified at 6 h by analyses of IL-6, IL-1β, IL-10, CXCL1, SAA1, HMGB1 and organ injury. Systemic IL-6 increased in all mono and multiple trauma groups, while CXCL1 increased only in HS, PT I, PT II and MT vs. control. Local inflammatory response was most prominent in HS, PT I, PT II and MT in the liver. Infiltration of inflammatory cells into lung and liver was significant in all multiple trauma groups vs. controls. Hepatic and pulmonary injury was prominent in HS, PT I, PT II and MT groups. These experimental multiple trauma models closely mimic the early post-traumatic inflammatory response in human. Though, the choice of read-out parameters is very important for therapeutic immune modulatory approaches.

Background: CrossFit is a relatively new sport with rapidly growing participation rates in the United States and around the world. We sought to determine risk factors for sustaining multiple CrossFit-related injuries requiring medical evaluation., Methods: CrossFit-related musculoskeletal injuries evaluated at a single hospital system (N.=837) were identified. For musculoskeletal injuries, use of physical therapy, injection, advanced diagnostic imaging including CT or MRI, and surgery were documented. Independent risk factors for sustaining multiple injuries requiring medical evaluation were assessed by multivariate logistic regression analysis., Results: A total of 94/837 (11.2%) underwent evaluation for 2 or more CrossFit-Related injuries (74% new injury to different body part; 26% subsequent injury, same body part). Independent risk factors for repeat injury (recurrent injury or second new injury) included increased length of follow-up (per year: OR 1.50 CI: 1.29, 1.75; P<0.001), initial injury during spring season (OR 2.03 CI: 1.27, 3.26; P=0.004), advanced imaging not obtained for evaluation of initial injury (OR 2.62 CI: 1.37, 5.02; P=0.002), course of physiotherapy completed for initial injury (2.00 CI: 1.17, 3.41; P=0.008), corticosteroid injection administered for initial injury (OR 2.43 CI: 1.21, 4.88; P=0.01), and increased age (per 5 year increase: OR 1.12 CI: 1.01, 1.24; P=0.03). These risk factors in combination had moderate discriminatory ability for identifying athletes at risk for multiple injuries., Conclusions: There are multiple risk factors for sustaining a recurrent or second new CrossFit-related injury requiring medical evaluation including older age, length of participation, and spring season participation. Risk factors for repeat injury related to initial evaluation and treatment include not receiving advanced imaging, receiving a corticosteroid injection, or undergoing physical therapy. The anatomic site of initial injury was not related to risk of subsequent injury in this population.

The multiple ligament injured knee is a complex problem in orthopedic surgery. These injuries may or may not present as acute knee dislocations, and careful assessment of the extremity vascular and neurological status is essential because of the possibility of arterial and/or venous compromise, and nerve injury. These complex injuries require a systematic approach to evaluation and treatment. Physical examination and imaging studies enable the surgeon to make a correct diagnosis and formulate a treatment plan. Knee stability is improved postoperatively when evaluated with knee ligament rating scales, arthrometer testing, and stress radiographic analysis. Surgical timing depends upon the injured ligaments, vascular status of the extremity, reduction stability, and the overall health of the patient. The use of allograft tissue is preferred because of the strength of these large grafts, and the absence of donor site morbidity.

The traumatic knee dislocation (KD) is a complex condition resulting in injury to >1 ligament or ligament complexes about the knee, termed multiligament knee injuries. Typically, KDs result in injury to both cruciate ligaments with variable injury to collateral ligament complexes. Very rarely, KD may occur with single cruciate injuries combined with collateral involvement but it is important to understand that not all multiligament knee injuries are KDs. Patients can present in a wide spectrum of severity; from frank dislocation of the tibiofemoral joint to a spontaneously reduced KD, either with or without neurovascular injury. The initial evaluation of these injuries should include a thorough patient history and physical examination, with particularly close attention to vascular status which has the most immediate treatment implications. Multiple classification systems have been developed for KDs, with the anatomic classification having the most practical application.

Purpose: To explore the epidemiological and clinical profile of patients admitted to the trauma and emergency department (TED) of a tertiary care hospital due to tropical cyclone Fani and highlight the challenges faced by the hospital in this natural disaster., Methods: A retrospective study was conducted in the TED in the affected zone. Data of all victims affected by the cyclone Fani on May 3, 2019 were obtained from disaster records and medical case sheets. All patients except death on admission were included. Clinical variables included anatomical sites and severity of injuries which was assessed by revised trauma score (RTS) and injury severity score (ISS). Trauma injury severity score (TRISS) was also calculated., Results: Of 75 patients, 74 were included and the other one was brought dead and thus excluded. The age, median ± interquartile range (IQ), was 41.0 (27.7-53.0) years. The male to female ratio was 2:1. Most of the wounded were transported by the police control room vans on day 1: first 10 h, 50.0%; 10-24 h, 20.3%. The median ± IQ range of RTS, ISS and TRISS were 20 (14-28), 7.84 (7.841-7.841), and 97.4 (91.6-98.9), respectively. Simple external injury was the dominant injury type. Polytrauma (ISS >15) was seen in 67% cases and spine injury in 14% cases (7% cervical and 7% thoracolumbar). Injury causes included sharp flying objects (broken pieces of glasses and asbestos) in 31% cases, followed by fall of trees in 20.3%. Twenty-four patients were discharged after primary treatment, 30 admitted to the indoor-trauma ward or intensive care unit and 20 deferred or transferred to another center. There was no in-house mortality. Challenges were related to electricity failure, mobile network breakdown, infrastructure collapse, and delay in expertise repair from outside due to airport/railway closure., Conclusion: In cyclonic storm like Fani, sharp flying objects, fall of trees/poles and collapsing walls constitute the common mode of injuries causing harm to more than one body regions. Polytrauma was seen in the majority of patients though external injury was the commonest. The affected hospital had the uphill task of treating hospitalized patients as well as disaster victims., (Copyright © 2020 Chinese Medical Association. Production and hosting by Elsevier B.V.

Importance: The nasal bone is one of the most commonly fractured bones of the midface. However, the frequency of coincident fractures of adjacent bones such as the frontal process of the maxillary bone, nasal septum, and medial or inferior orbital walls has not been fully evaluated. Objective: The purpose of this study was to investigate the incidence of fractures of adjacent structures in the setting of a nasal bone fracture. Second, we propose a new classification system of nasal bone fractures with involvement of adjacent bony structures. Design, Setting, and Participants: One thousand, one hundred ninety-three patients with midfacial fractures were retrospectively reviewed. The characteristics of fractures of the nasal bone and the incidence of coincident fractures of the frontal process of maxilla, bony nasal septum, medial, or inferior orbital walls were analyzed. Exposure: All patients included in the study presented with nasal trauma. Main Outcomes and Measures: The coincident fractures of adjacent midfacial structures were assessed, and a new classification of midfacial fractures based on computed tomography (CT) scan images was proposed. Results: Among the 1193 cases, bilateral fractures of the nasal bone were most common (69.24%), and coexistent fracture of the frontal process of the maxilla and bony nasal septum was 66.89% and 42.25%, respectively. Coincident fracture of the orbital walls was observed in 16.51% of cases. The major etiology of fracture for the younger and elderly groups was falls, compared with assault as the most common etiology in the adult group. A classification scheme was generated in which fractures of the nasal bone were divided into five types depending on coexisting fractures of adjacent structures. Conclusions and Relevance: External force applied to the nasal bone can also lead to coexistent fracture of adjacent bony structures including the frontal process of the maxilla, nasal septum, and orbital walls. The proposed classification of nasal fracture based on CT imaging helps to incorporate coincident disruption of adjacent structures.

Introduction: This study sought to expand the very limited data on Scandinavian paediatric poly-trauma patients by charactering patients from this population admitted to a Danish level-1 trauma centre., Methods: This retrospective cohort study included all patients 15 years or younger who were admitted to the trauma centre at Aarhus University Hospital, Denmark from January 2000 to May 2014. Injury severity was calculated using the Injury Severity Score (ISS). The Wilcoxon rank-sum test was used to determine significant differences between sexes., Results: A total of 880 children (499 boys and 391 girls) were included. No significant sex-related differences were observed in the numbers admitted during the study period, age at admission or severity of injuries. Overall, 30% of the paediatric patients were admitted in the afternoon (3-6 p.m.). The crude death rate was 2.7% of all admissions. Traffic accidents accounted for 48% of all admissions and two-thirds of all deaths. All non-survivors received ISSs of 16 or higher, and 20% of deaths in this group and 42% of overall deaths occurred within the first 24 hours., Conclusions: Our study suggests that in Denmark, children admitted to a trauma centre are most likely to have been injured in traffic accidents and/or in the afternoon. Deaths were few and limited to the severely injured children; many survived despite severe injuries., Funding: none., Trial Registration: not relevant., (Articles published in the DMJ are “open access”.

Background: The mortality rate is very high for patients with severe multiple trauma with massive pulmonary contusion containing intrapulmonary hemorrhage. Multiple treatment modalities are needed not only for a prevention of cardiac arrest and quick hemostasis against multiple injuries, but also for recovery of oxygenation to save the patient's life., Case Presentation: A 48-year-old Japanese woman fell down stairs that had a height of approximately 4 m. An X-ray showed pneumothorax, pulmonary contusion in her right lung, and an unstable pelvic fracture. A chest drain was inserted and preperitoneal pelvic packing was performed to control bleeding, performing resuscitative endovascular balloon occlusion of the aorta. A computed tomography scan revealed massive lung contusion in the lower lobe of her right lung, pelvic fractures, and multiple fractures and hematoma in other areas. An emergency thoracotomy was performed, and then we performed wide wedge resection of the injured lung, clamping proximal to suture lines with two Satinsky blood vessel clamps. The vessel clamps were left in the right thoracic cavity. The other hemorrhagic areas were embolized by transcatheter arterial embolization. However, since her respiratory functions deteriorated in the intensive care unit, veno-venous extracorporeal membrane oxygenation was used for lung assist. Planned reoperation under veno-venous extracorporeal membrane oxygenation was performed on day 2. Since her respiratory condition improved gradually, the veno-venous extracorporeal membrane oxygenation circuit was withdrawn on day 7. She was transferred to the psychiatric ward of our hospital on day 75., Conclusion: Utilizing multiple treatment modalities such as resuscitative endovascular balloon occlusion of the aorta, damage control surgery, transcatheter arterial embolization, and veno-venous extracorporeal membrane oxygenation with appropriate timing saves a patient with severe polytrauma with massive pulmonary contusion including intrapulmonary hemorrhage.

Purpose: Within the UK there is a continued expansion of the population over the age of 65, this currently accounts for 17.8% of the British population. We review the impact that centralization of Major Trauma has had, as well as analysing for significant predictors of poor outcome., Method: All patients presenting to Leeds Major Trauma Centre as a 'Major Trauma' who were equal to or over the age of 65 were included in this study. Prospectively collected data from the Trauma Audit Research Network (TARN) was collated to include the above data set from the 1st April 2012 - 1st April 2016. The 1st April 2012 represents the commencement of the Major Trauma Network within Yorkshire. To allow more quantative assessment of patients' co-morbidities, they were coded as per Charlson Co-morbidity Index for analysis., Results: 1167 patients presented within the above timeframe. Mean age was 79.5 (range 65-103.5). Mean ISS was 14.8 of the entire cohort. Mortality was 12.9% of the entire cohort. The leading mechanisms of injury were from low energy falls <2m-59.89%, Fall >2m-23.05% and Road Traffic Collision - 16.45%., Conclusion: Mortality rates since the commencement of the Major Trauma Network within this age group have reduced. This is likely secondary to centralization of major trauma. Variables found to be statistically significant with increased mortality were increasing age, head injury, presence of Chronic Lung Disease, presence of metastases, decreased GCS and increased ISS., (Copyright © 2019 Royal College of Surgeons of Edinburgh (Scottish charity number SC005317) and Royal College of Surgeons in Ireland.

Clinical Issue: The mean number of trauma room admissions and applied CT dose increase as the severity of injuries decreases. Therefore, appropriateness of established procedures should be re-evaluated., Standard Radiological Methods: Considering severely injured patients with an Injury Severity Score (ISS) ≥16, whole body CT (WB-CT) compared to selective CT decreased mortality by about 25%. Thus, the ISS is a good indicator for the severity of injuries. However, since ISS can only be determined after diagnosis, it does not help with the primary assessment., Methodological Innovation and Evaluation: In addition to the currently used very fast WB-CT protocol with the highest diagnostic precision, a second protocol should be established applying a substantially lower dose. Under ongoing resuscitation, WB-CT often makes a substantial contribution towards targeted therapy or to justifying the discontinuation of resuscitation measures. The WB-CT findings should be performed several times and, at least in the acute emergency situation, it should follow the ABCDE scheme as close as possible., Practical Recommendations: In the trauma room it should be initially decided whether the classification as polytrauma is to be maintained. If yes, every institution should provide a dose-reduced WB-CT protocol in addition to the maximum variant used so far. Dose-reduced WB-CT seems to be appropriate for stable and oriented patients, who receive a CT primarily because of the trauma mechanism. Even under resuscitation conditions, WB-CT is easy to perform and medically as well as ethically of high value. The reporting and communication should be structured according to "diagnose first what kills first".

Battered child syndrome (BCS) is a form of physical abuse that is characterised by multiple injuries and potentially fatal outcome. Despite the high prevalence of physical abuse in developing countries, BCS is rarely reported. Hence, this report highlighted a four-year-old Nigerian boy who suffered multiple injuries (scalp haematoma, bruises, right clavicular fracture, and burns) from the paternal uncle's wife. This case report is discussed along the line of public health approach for curbing the social menace., Competing Interests: The authors declare no competing interests., (© Olayinka Rasheed Ibrahim et al.)

We report a 28-year-old man admitted postmotorcycle versus car in September 2017. The patient sustained multiple injuries in both the upper and lower limbs. He sustained a complex brachial plexus injury on his left side and was transferred immediately to Stanmore Hospital to undergo specialist surgery (supraclavicular brachial plexus exploration and neurolysis) to repair his brachial plexus injury. The patient was transferred back to the specialist trauma ward for additional surgeries for his subsequent injuries. Due to the complexity of the injury and surgery the patient was not able to start rehabilitation until six weeks post operation, at which point he was referred to outpatient physiotherapy. Prior to this his left upper limb was in a sling but was instructed to move it as able. The patient commenced his comprehensive physiotherapy programme in January 2018., Competing Interests: Competing interests: None declared., (© BMJ Publishing Group Limited 2019. No commercial re-use.

Blunt traumatic aortic injury (BTAI) is a rare but life-threatening emergency that is usually caused by sudden acceleration/deceleration injuries in vehicular accidents. We describe our initial experience of a retrograde two-stage hybrid treatment approach for the emergent management of a 63-year-old motorcyclist who presented with a complicated BTAI with malperfusion syndrome. To our best knowledge, this uncommon BTAI case with fatal distal malperfusion saved by an urgent retrograde two-stage hybrid procedure has been reported rarely. This early reperfusion strategy with two-stage retrograde endovascular technique could be an effective and life-saving treatment option for polytrauma patients with suitable aortic anatomy., (Copyright © 2019 Society for Vascular Surgery.

Background: This study aimed to determine the incidence of intra-abdominal injuries in elderly patients after a ground-level fall., Methods: A 6-year retrospective review was conducted on patients 65 years of age or older involved in a fall from standing and evaluated at a level 1 trauma center. Each patient presented with a pelvic, thoracolumbar, and/or lower rib fracture. Data collection included demographics, injury characteristics, FAST exam results, CT imaging results, and hospitalization outcomes., Results: A total of 324 patients met study inclusion criteria. The majority of patients were white (95.1%) females (65.4%) with an average age of 82.0 ± 7.3 years. Only 22 patients (6.8%) reported abdominal pain, although an abdominal CT was performed in 91 patients (28.1%). Only 1 patient (0.3%) was found to have an intra-abdominal injury when no abdominal pain was reported and the FAST exam was negative. This injury was not clinically significant enough to warrant surgical intervention., Conclusion: Elderly patients who suffer a ground-level fall do not benefit from PAN-SCAN, even when presenting with rib, thoracolumbar, and/or pelvic fractures., (Copyright © 2018 Elsevier Inc.

Trauma and hemorrhagic shock can lead to acute traumatic coagulopathy (ATC) that is not fully reversed by prehospital resuscitation as simulated with a limited volume of fresh whole blood (FWB) in a rat model. Tranexamic Acid (TXA) is used as an anti-fibrinolytic agent to reduce surgical bleeding if administered prior to or during surgery, and to improve survival in trauma if given early after trauma. It is not clear from the existing clinical literature whether TXA has the same mechanism of action in both settings. This study sought to explore the molecular mechanisms of TXA activity in trauma and determine whether administration of TXA as a supplement to FWB resuscitation could attenuate the established ATC in a rat model simulating prehospital resuscitation of polytrauma and hemorrhagic shock. In a parallel in-vitro study, the effects on clotting assays of adding plasmin at varying doses along with either simultaneous addition of TXA or pre-incubation with TXA were measured, and the results suggested that maximum anti-fibrinolytic effect of TXA on plasmin-induced fibrinolysis required pre-incubation of TXA and plasmin prior to clot initiation. In the rat model, ATC was induced by polytrauma followed by 40% hemorrhage. One hour after trauma, the rats were resuscitated with FWB collected from donor rats. Vehicle or TXA (10mg/kg) was given as bolus either before trauma (TXA-BT), or 45min after trauma prior to resuscitation (TXA-AT). The TXA-BT group was included to contrast the coagulation effects of TXA when used as it is in elective surgery vs. what is actually feasible in real trauma patients (TXA-AT group). A single dose of TXA prior to trauma significantly delayed the onset of ATC from 30min to 120min after trauma as measured by a rise in prothrombin time (PT). The plasma d-dimer as well as plasminogen/fibrinogen ratio in traumatized liver of TXA-BT were significantly lower as compared to vehicle and TXA-AT. Wet/dry weight ratio and leukocytes infiltration of lungs were significantly decreased only if TXA was administrated later, prior to resuscitation (TXA-AT). In conclusion: Limited prehospital trauma resuscitation that includes FWB and TXA may not correct established systemic ATC, but rather may improve overall outcomes of resuscitation by attenuation of acute lung injury. By contrast, TXA given prior to trauma reduced levels of fibrinolysis at the site of tissue injury and circulatory d-dimer, and delayed development of coagulopathy independent of reduction of fibrinogen levels following trauma. These findings highlight the importance of early administration of TXA in trauma, and suggest that further optimization of dosing protocols in trauma to exploit TXA's various sites and modes of action may further improve patient outcomes., Competing Interests: The authors have declared that no competing interests exist.

Approximately 3% of all joint dislocations involve the hip joint, and only 8-10% of these will be anterior. Traumatic anterior open dislocation of the hip is rare in children and prone to be associated with injuries, extensive soft tissue damage, and avascular necrosis of the femoral head. We present a case of a 13-year-old boy who had an open anterior dislocation of the hip with ipsilateral avulsion of the greater trochanter after a tractor wheel crush in an agricultural accident. Additional lesions included a diaphyseal closed fracture of the contralateral femur. We report this case because of the rarity and seriousness of this injury due to its progressive complications and difficulties related to its management., (Copyright © 2019 French Society of Pediatrics.

Background: Road Traffic Accidents have become an enormous global public health problem killing approximately 1.25 million people and injuring 20 to 50 million others yearly. It is the 10th leading cause of death universally and the number one cause of mortality of the young population between the ages of 5 and 29. Only few studies have been conducted on the severity of road traffic injuries in Ethiopia hence the need for the study., Objective: To assess injury severity level and associated factors among road traffic accident victims., Methods: A cross-sectional study of patients involved in road traffic accident and attended Tirunesh Beijing hospital, Addis Ababa, Ethiopia. Victims were consecutively recruited until sample size (164) attained during the study period. Data collectors administered a structured questionnaire. The collected data was then entered and cleaned using Epi info and exported to IBM SPSS for statistical analysis. Independent factors associated with injury severity were assessed using bivariate and multivariate logistic regression., Results: A total of 164 road traffic injury victims were included to the study. Prevalence of severe injury accounted for 36.6% of cases. "can read and write" educational status OR 35.194(95% CI; 3.325-372.539), sustaining multiple injury OR 18.400(95% CI; 5.402-62.671), sustaining multiple injury type OR 6.955(95% CI; 1.716-28.185) and being transported by ambulance from the scene of accident OR 13.800(95% CI; 1.481-128.635) were the explanatory variables found to have a statistically significant association with severe injury., Conclusion: This study showed road traffic accident is predominantly affecting the economically active, male young population. Not a single victim received pre-hospital care, majority were extracted by bystanders and most used commercial vehicle to be transported to a health institution reflecting the need for improvements in pre-hospital emergency services and socio-economic related infrastructures., Competing Interests: The authors have declared that no competing interests exist.

Background: The aims of the present study were to establish a clinically relevant two-hit model with trauma/hemorrhage followed by sepsis in older mice and investigate age-dependent cardiovascular and immunologic specificities under these conditions., Materials and Methods: In aged mice (12, 18, and 24 mo old), a femur fracture followed by hemorrhage was induced. After resuscitation, animals were monitored for 72 h before sepsis was induced. Vital signs were monitored during shock. Systemic interleukin (IL)-6 levels were measured daily. Expression of sarcoplasmic or endoplasmic reticulum calcium ATPase (SERCA) and IL-6 receptor were analyzed in heart, lung, and liver tissues., Results: After induction of shock, mean arterial pressure decreased significantly in all groups (12 mo, P < 0.001; 18 mo, P < 0.001; 24 mo, P = 0.013). Compared with younger animals, 24-mo old mice were not able to adequately compensate for hypovolemia by an increase of heart rate (P = 0.711). Expression of SERCA2 (P = 0.002) and IL-6 receptor on myocytes (P = 0.037), lung (P = 0.005), and liver (P = 0.009) tissues were also lowest in this group. Systemic IL-6 values showed the most distinct posttraumatic response in 24-mo-old mice (P = 0.016). Survival rate decreased significantly with increased age (P = 0.005)., Conclusions: The increased mortality rate in older animals was associated with a limited compensatory physiological response and a more distinct immunologic reaction after trauma and sepsis. A decreased SERCA2 expression and missing feedback loops due to a reduced density of organ bound immune receptors might represent possible explanations for the observed age-dependent differences., (Copyright © 2019 Elsevier Inc.

In dealing with a scooter-related traffic accident with rider death, it is necessary to identify the driver responsible for the accident. This study aimed to reconstruct the kinematics of a scooter-microvan accident involving three riders and explored the differences in injury risks and characteristics of the scooter driver and passengers. We reconstructed a real accident by using MADYMO multi-body simulation software. Moreover, we designed two-variable simulation experiments to analyze how the velocity and impact angle of the microvan are related to the injuries of the three riders. When the microvan speed is set at 18 km/h and that of the scooter is set at 28.8 km/h, the simulated kinematics correlates well with real accident data, and the impact positions and injury parameters correlate well with the actual injuries. When the impact angle is smaller than 30° and the microvan impact velocity is lower than 40 km/h, the head injury of the driver is more life-threatening than the corresponding injuries of the rear passengers. When the impact angle is 15° and the microvan impact velocity is in the range of 0-20 km/h, the femur fracture risk is higher for the driver than for passengers. As the impact angle increases to 45°, passengers have a higher risk of femur fracture than the driver in the velocity range of 0-10 km/h. This impact velocity range becomes 0-30 km/h at an impact angle of 60° and then 40-70 km/h at an impact angle of 90°. Our study shows that the multibody method can reconstruct accidents and predict the different injury features and risks between the driver and passengers, which is useful in identifying the driver., (Copyright © 2019 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Portopulmonary hypertension (PoPH) is a well-recognized complication of portal hypertension. This study reports a case of PoPH that was secondarily caused by post-traumatic mesenteric arteriovenous fistula. A 38-year-old man with a history of knife stabbing wounds in the abdomen in 2003 was admitted to the hospital with exertional shortness of breath and a mechanic murmur over the umbilical region. Computed tomography indicated signs of PoPH and mesenteric arteriovenous fistula. Percutaneous catheter-directed embolization was first performed but failed. Subsequently, the patient was successfully treated with fistula resection and partial enterectomy. The patient had been postoperatively followed regularly, and chief symptoms had been alleviated significantly and pulmonary pressure had successfully decreased to normal range. We believe that this is the first case of PoPH caused by mesenteric arteriovenous fistula., (Copyright © 2019 The Authors. Published by Elsevier Inc. All rights reserved.)

A mass casualty incident (MCI) can have an enormous impact on an already crowded emergency department (ED), affecting the quality of health care provided to non-MCI ED patients. On June 26, 2015, a burn MCI (BMCI) occurred due to a cornstarch explosion at a party at a water park. The competing needs of the BMCI patients might have crowded out the needs of the non-BMCI patients. Although crowd-out effects have been previously documented in a variety of health care situations, they have not been extensively evaluated during MCIs. We aimed to determine whether the outcomes of the non-MCI patients were compromised during this incident.We conducted a retrospective observational study comparing several health care parameters and outcomes between non-BMCI patients and historical controls during the designated period using institutional electronic records and the National Health Insurance Research Database.On the night of the incident, 53 patients were sent to our ED; most of them arrived within 3 hours after the BMCI. There was a significant increase in the wait time for ICU beds among non-BMCI patients compared to the wait times during the corresponding week of the previous year (8.09 ± 4.21 hours vs 3.77 ± 2.15 hours, P = .008). At the hospital level, there was a significantly increased length of hospital stay (LOS) in the ICU after the MCI compared with the LOS in the ICU in the same week of the preceding year (median days: 15 vs 8, P ≤ .001). At the regional level, there were no significant differences between the 2 periods in the LOS in acute care, LOS in the ICU or mortality rates at the involved medical centers.Crowd-out effects from the MCI occurred in the ED and at the institutional level. Although there was an increased wait time for admission to the ICU and a longer LOS in the ICU, the LOS in acute care beds, treatment of time-sensitive diseases, and mortality rates were not compromised by the current MCI protocol at either the institutional or regional levels.

Objective: To determine free and total cortisol serum concentrations in the first 24 h after trauma and to evaluate the influence of traumatic brain injury (TBI) on their dynamics., Methods: This prospective cohort study enrolled patients who had experienced multiple trauma and were admitted to a level 1 trauma centre. The patients were divided in two groups based on the presence of TBI according to clinical and radiological findings. Blood was collected initially as well as at 12 h and 24 h after the traumatic injury. Total cortisol, corticosteroid binding globulin (CBG) and free cortisol levels were determined., Results: The study analysed data from 49 patients (36 males and 13 females) with a mean ± SD age of 45.0 ± 16.0 years. Of these, 36 presented with TBI and 13 had multiple injuries without TBI. Patients with TBI showed significantly lower concentrations of total cortisol and free cortisol compared with patients without TBI. Repeated measures analysis revealed different concentration dynamics in patients with TBI, with no increase in cortisol after trauma., Conclusion: Multiple trauma patients with TBI are at risk of acute impaired cortisol secretion and show an attenuated stress response as early as 12 h after injury.

The author presents a case study of the use of resuscitative endovascular balloon occlusion (REBOA) as a suitable alternative to thoracotomy and clamping of the descending aorta to control retroperitoneal bleeding in a patient with a pelvic injury. The patient who suffered multiple trauma after car accident, type C pelvic injury and retroperitoneal bleeding among other things, was following the pre-hospital ambulance care transported to the department of emergency medicine, with catecholamine infusion to support the blood flow. After the primary survey following the ATLS principles, the patient was taken for a CT scan. The CT examination revealed also multiple sources of retroperitoneal bleeding. Subsequently, the patient was brought to the operating room, where endovascular balloon occlusion of the descending aorta was performed to temporarily control retroperitoneal bleeding, which provided more time to treat the patient in line with the damage control surgery principles. In bleeding patients who suffered blunt torso traumas and serious haemorrhagic shock, or patients "in extremis", the survival after emergency thoracotomy ranges only around 1%. The to date results of REBOA technique applied in same indications are very promising globally. The survival rate increases multiple times especially in hypotensive patients, without the necessity of their immediate cardiopulmonary resuscitation. Key words:resuscitative balloon occlusion of the aorta, REBOA, haemorrhagic shock, retroperitoneal bleeding.

Dragging injuries caused by automobiles involved in an accident are occasionally reported; however, those without injury to the thoracoabdominal organs are rare. We present an autopsy case of a man in his 20s found dead on the road after being dragged by a passenger automobile for a distance of 3.4 km. The accident caused fatal dragging injuries but no thoracoabdominal injuries. The victim appeared to be drunk and was lying on the road in front of the parked automobile. Dragging injuries are a unique type of traffic accident that sometimes result from limited and poor visibility due to darkness, rain, or fog. In particular, lying on the road in a drunken state is a specific risk factor for dragging injuries. The dragging distance, road-surface properties, strength of pressure applied by the underbody of the automobile, and the victim's posture are considered to affect the distribution and degree of dragging injuries. Based on autopsy findings and eyewitness testimonies, we discuss the injury mechanism and attempt to reconstruct the accident.

Lethal donkey attacks have very rarely been described. The case of a 65-year-old man who was found deceased on a country road with 2 domestic donkeys nearby is, therefore, reported. Examination of the body revealed contusions and lacerations of the face and scalp, a comminuted fracture of the left maxilla, comminuted fracturing of the right radius and ulna and of the left anterior superior iliac spine, a flail chest, and pulmonary contusions. In addition, there were bite marks on the left thigh, right buttock, right axilla/upper arm, and left cheek which corresponded to the dental arcades of the donkeys. Death had resulted from blunt chest trauma due to an attack by 1 or 2 donkeys. Deaths and serious injuries are much more commonly caused by horses; however, this case shows that even domesticated donkeys may also rarely be capable of inflicting significant trauma and so should be approached with circumspection.

A 49-year-old female sustained a polytrauma after being hit by a vehicle in a traffic accident. Following the incident, the woman had various surgical interventions and underwent intensive care over a 6-week period. Eight months later, she died after developing secondary sclerosing cholangitis (SSC). Autopsy revealed liver failure and hepatic encephalopathy due to SSC caused by the polytrauma and the subsequent intensive care. Prior to the accident, there was no evidence of a pre-existing liver or biliary system disease. The death of the patient was classified as non-natural as a causal consequence of the traffic accident. SSC has been clinically described as a complication of intensive care. Since it has a high mortality rate, it is important that forensics and pathologists are aware of the condition.

A 24-year-old man was involved in a high-velocity motor vehicle accident with polytrauma 2 years after implantation of a copolymer phakic IOL (pIOL) (Visian ICL). After being released from the intensive care unit, he reported decreased vision, pain, glare, and photophobia and was treated for hyphema without globe rupture. He was found to be aniridic during anterior chamber washout of the hyphema. In the first reported case, to our knowledge, of aniridia after pIOL placement, blunt trauma likely caused expulsion of the iris through dehiscence of the previously placed wound for pIOL implantation., (Published by Elsevier Inc.)

The earliest mention of a stowaway in the wheel well of an airplane dates back to 1947: A 30-year-old man chose this mode of travel for a trip from Lisbon to Brazil and survived (Véronneau et al., 1996). In a retrospective study, we evaluated cases with lethal outcome of stowaways in airplane wheel wells by focusing on forensic autopsy results, in particular, in regard to hypothermia, hypoxia, and injuries. In addition, the flight routes, flight altitudes, and flight durations were analyzed. Using the forensik ® program, a search of all the autopsies performed between 1994-2017 at the Institute of Legal Medicine in Frankfurt am Main, Germany, was conducted, using the key words "airplane," "flights," and "wheel well." All of the thus retrieved autopsy reports, medicolegal expert reports, and police investigation reports were then evaluated. Five cases were included in our study. The decedents were all men, aged between 14 and 26 years. Four of the decedents had been discovered at the Frankfurt Main airport within airplane wheel wells; the fifth man had been discovered in a woods underlying one of the flight approach paths to the airport. Two stowaways had died of hypoxic asphyxiation, possibly in conjunction with hypothermia as a contributing factor. One stowaway died of the polytrauma he sustained when he was crushed by retracting landing gear. For a further stowaway, the cause of death could not be macroscopically determined at autopsy. In one case, only an external postmortem examination had been performed, without autopsy. Analysis of the flight routes, altitudes, and durations showed that the flights had been international flights, the flight altitudes had varied between 7000m (∼23,000ft) und 11,000m (∼36,000ft), and the flight duration had been between 4 and 9.5h. At high altitudes, the ambient conditions in wheel wells, which are not pressurized, are rarely survived by stowaways, with hypoxic asphyxiation likely posing greater peril than hypothermia. Further dangers are that of being crushed by retracting landing gear after takeoff, or of falling out of a wheel well, from a great height, when the landing gear is deployed. When it appears conceivable that a stowaway may have fallen from an aircraft wheel well during landing or takeoff, an autopsy and discovery scene investigation are essential to reconstructing the course of events., (Copyright © 2018 Elsevier B.V.

The water jet pack is a relatively new and very exciting sporting activity for adventure seekers. However, there are some concerns raised in terms of safety, and some sporadic reports have appeared in newspapers about the injuries sustained from this sport. We are presenting an unfortunate case where a teenaged girl fell from a jet pack and sustained serious injuries including the loss of her kidney. This is the first reported serious injury from the Jet pack (Carbon Sports GmbH, Itzehoe, Germany).

Explosions account for 79% of combat related injuries and often lead to polytrauma, a majority of which include blast-induced traumatic brain injuries (bTBI). These injuries lead to internal bleeding in multiple organs and, in the case of bTBI, long term neurological deficits. Currently, there are no treatments for internal bleeding beyond fluid resuscitation and surgery. There is also a dearth of treatments for TBI. We have developed a novel approach using hemostatic nanoparticles that encapsulate an anti-inflammatory, dexamethasone, to stop the bleeding and reduce inflammation after injury. We hypothesize that this will improve not only survival but long term functional outcomes after blast polytrauma. Poly(lactic-co-glycolic acid) hemostatic nanoparticles encapsulating dexamethasone (hDNPs) were fabricated and tested following injury along with appropriate controls. Rats were exposed to a single blast wave using an Advanced Blast Simulator, inducing primary blast lung and bTBI. Survival was elevated in the hDNPs group compared to controls. Elevated anxiety parameters were found in the controls, compared to hDNPs. Histological analysis indicated that apoptosis and blood-brain barrier disruption in the amygdala were significantly increased in the controls compared to the hDNPs and sham groups. Immediate intervention is crucial to mitigate injury mechanisms that contribute to emotional deficits.

Drones are increasingly being used by children and adults recreationally and commercially. The propeller blades when spinning at high speeds may cause serious harm to the eye and orbital structures.

We report a case of traumatic disruption of the aortic root with multisystem trauma. A 45-year-old male was suffered from multiple injuries including subarachnoid hemorrhage, lung contusion, retroperitoneal hematoma and femoral bone fracture caused by a traffic accident. He had a history of 3 cardiac surgeries including repair of atrioventricular septal defect and mitral valve replacement using a mechanical valve. Contrast-enhanced computed tomography (CT) revealed leakage of the contrast medium from the aortic root and a filling defect on the right coronary artery. Because of hemorrhagic complications, emergency operation was avoided. He was operated 2 days after the trauma. Laceration of the left-coronary sinus and the non-coronary sinus was observed. Bentall operation was performed and the right coronary artery( RCA) was bypassed with a saphenous vein graft. He was treated with open fixation of the right femur 14 days after the operation and was discharged 58 days after the 1st operation.
