A Comprehensive Analysis of the Radiation Exposure and the Diagnostic Benefit of PanCT in Pediatric Cases with Multiple Trauma.

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.

[Tourniquet use in the Helicopter Emergency Medical Service : Analysis based on data of the DRF Luftrettung (German Air Rescue) in the period 2015-2020]. / Der Einsatz von Tourniquets im Rahmen der Luftrettung : Analyse anhand der Daten der DRF Luftrettung im Zeitraum 2015­2020.

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 χ2-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, SpO2) 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.

[The nurse facing a polytrauma patient]. / L'infirmière face à un patient polytraumatisé.

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.

The Self-Inflicted Multiple Organs Injury with Nail Gun.

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.

Camel-Related Deaths-A Forensic Overview.

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.

Injury and treatment patterns of ballistic pelvic fractures by anatomic location.

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.

What predicts mortality in the elderly patient presenting as a trauma call? A report from a Major Trauma Centre.

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.

[Update polytrauma and computed tomography in ongoing resuscitation : ABCDE and "diagnose first what kills first"]. / Update Polytrauma und Computertomographie unter Reanimationsbedingungen : ABCDE und "diagnose first what kills first".

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".

Tropical cyclone Fani-perspective from the trauma and emergency department of an affected tertiary hospital.

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.

Fatal mauling by tigers.

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.

Urgent retrograde two-stage hybrid repair of a complicated blunt traumatic aortic injury.

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.

Geriatric Polytrauma-Cardiovascular and Immunologic Response in a Murine Two-Hit Model of Trauma.

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.

Portopulmonary Hypertension: A Complex Case Derived from Multiple Penetrating Trauma-Induced Mesenteric Arteriovenous Fistulae.

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.

[Role of Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) to Save Life in Bleeding in a Patient with a Pelvic Ring Injury]. / Role balonové endovaskulární okluze aorty (REBOA) pri záchrane zivota u pacientu s krvácením z pánve.

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.

Secondary sclerosing cholangitis in critically ill patients after a traffic accident-a new entity that should be considered in death classification.

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.

An Autopsy Case of Injuries Caused by Automobile Dragging for a Distance of 3.4 km Without Thoracoabdominal Organ Injuries.

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.

Autopsy Features of Fatal Donkey Attack.

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.

Jet Pack Fun that Went Wrong: A Case of Serious Multivisceral Injuries From Water Sports.

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).

[Traumatic Disruption of the Aortic Root and the Ascending Aorta with Multisystem Trauma;Report of a Case].

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.

Trauma in elderly patients: a study of prevalence, comorbidities and gender differences.

AIM: Trauma, in geriatric patients, increases with age, and is a leading cause of disability and institutionalization, resulting in morbidity and mortality. The aim of our study was to analyse the prevalence of trauma, the related risk factors, mortality and sex differences in the prevalence in a geriatric population. PATIENTS AND METHOD: We observed 4,554 patients (≥65 years) with home injuries or car accidents. Patients were evaluated with ISS (Injury Severity Score) and major trauma with ATLS (Advanced Trauma Life Support). The instrumental investigation was in the first instance, targeted X-Ray or whole-body CT. RESULTS: In over four years of study we treated 4,554 geriatric: 2,809 females and 1,745 Males. When the type of trauma was analysed the most common was head injury, followed by fractures of lower and upper limbs. In our experience hospitalization mainly involved patients over 80. In all patients mortality during assessment was 0.06%. DISCUSSION: The geriatric patient is often defined as a "frail elderly", for the presence of a greater "injury sensitivity". This is due to the simultaneous presence of comorbidity, progressive loss of full autonomy and exposure to a high risk of traumatic events. Optimal management of the trauma patient can considerable reduce mortality and morbidity. CONCLUSIONS: Falls and injuries in geriatric age are more frequent in women than in men. Among typical elder comorbidities, osteoporosis certainly causes a female preponderance in the prevalence of fractures. Our discharge data demonstrate that disability, which requires transfer to health care institutions, has a greater effect on women than men.
