RESUMO

BACKGROUND: Although post-traumatic stress disorder (PTSD) and depression screening are recommended for traumatic injury patients, routine screening is still uncommon. Salivary inflammatory biomarkers have biological plausibility and potential feasibility and acceptability for screening. This study tested prospective associations between several salivary inflammatory biomarkers (proinflammatory cytokines interleukin-1ß, interleukin-6, tumor necrosis factor-α; and C-reactive protein), collected during hospitalization and PTSD and depressive symptoms at 5-month follow-up. METHODS: Adult traumatic injury patients (N = 696) at a major urban Level 1 trauma center provided salivary samples and completed PTSD and depressive symptom measures during days 0-13 of inpatient hospitalization. At 5-month follow-up, 368 patients (77 % male, 23 % female) completed the Clinician-Administered PTSD Scale for DSM-IV and the Self-rated Inventory of Depressive Symptomatology. Analyses focused on a latent inflammatory cytokine factor and C-reactive protein at baseline predicting 5-month PTSD and depression symptom outcomes and included baseline symptom levels as covariates. RESULTS: A latent factor representing proinflammatory cytokines was not related to 5-month PTSD or depressive symptom severity. Higher salivary CRP was related to greater PTSD symptom severity (ß = .10, p = .03) at 5-month follow-up and more severity in the following depressive symptoms: changes in weight and appetite, bodily complaints, and constipation/diarrhea (ß's from .14 to .16, p's from .004 -.03). CONCLUSION: In a primarily Latine and Black trauma patient sample, salivary CRP measured after traumatic injury was related to greater PTSD symptom severity and severity in several depressive symptom clusters. Our preliminary findings suggest that salivary or systemic CRP may be useful to include in models predicting post-trauma psychopathology.

RESUMO

INTRODUCTION: Tranexamic acid (TXA) has been used as an adjunct in traumatic hemorrhage management. Outside of trauma, TXA has been used to limit blood loss across multiple surgical fields. TXA has also been found to have an immune-modulating effect, reducing postoperative infection rates. However, the relationship between TXA and infection rates in trauma patients is unclear. METHODS: We performed a single-institution retrospective cohort analysis of 364 trauma patients who underwent massive transfusion protocol activation at a level-one trauma level center over a 7-y period. Patients were placed into two groups based on TXA administration (No TXA and TXA). Minors, patients on anticoagulants, pregnant patients, and those who died upon arrival or were hospitalized for less than 1 d were excluded. Univariate and multivariate analysis with propensity score matching were used to evaluate the association between TXA and infection rates. RESULTS: Sixty-one patients (16.8%) received TXA, and 303 patients (83.2%) did not. TXA was associated with an increased risk of infection on univariate analysis (P = 0.007). However, on multivariate analysis after propensity score matching, TXA was not associated with infection (P = 0.975) while total hospital days and total ventilator days were associated with an increased risk of infection (P = 0.012, P = 0.014). CONCLUSIONS: Our study found no association between TXA and infection rates among our patient cohort. While TXA remains an important adjunct in trauma resuscitation, we did not find an association between TXA and infection in trauma patients.

RESUMO

PURPOSE OF REVIEW: To evaluate the role of sedation vacations in optimizing patient outcomes and enhancing the quality of care in neurological intensive care units (ICUs). We discuss the importance of sedation management in neurocritical care, considering recent research findings and clinical guidelines. RECENT FINDINGS: Recent studies have highlighted the significance of sedation interruption protocols in improving patient outcomes in the ICU setting. Evidence suggests that daily sedation interruptions can reduce the duration of mechanical ventilation, ICU length of stay, and mortality rates. However, the implementation of these protocols requires careful consideration of patient-specific factors and a multidisciplinary approach. Sedation vacations play a critical role in neurocritical care by reducing mechanical ventilation duration, ICU stay length, and mortality rates. Despite the benefits, the presence of complications must be addressed to avoid adverse outcomes. Continued research is necessary to refine these strategies and improve guideline quality, ensuring safe and effective sedation management in critically ill neurological patients.

RESUMO

Ballistic shields protect users from a variety of threats, including projectiles. Shield back-face deformation (BFD) is the result of the shield deflecting or absorbing a projectile and deforming toward the user. Back-face deformation can result in localized blunt loading to the upper extremity, where the shield is supported by the user. Two vulnerable locations along the upper extremity were investigated-the wrist and elbow-on eight postmortem human subjects (PMHS) using a pneumatic impacting apparatus for investigating the fracture threshold as a result of behind shield blunt trauma (BSBT). Impacting parameters were established by subjecting an augmented WorldSID anthropomorphic test device (ATD) positioned behind a ballistic shield to ballistic impacts. These data were used to form the impact parameters applied to PMHS, where the wrist most frequently fractured at the distal radius and the elbow most frequently fractured at the radial head. The fracture threshold for the wrist was 5663±1386 N (mean±standard deviation), higher than the elbow at 4765±894 N (though not significantly, p = 0.15). The failure impact velocity for wrist impacts was 17.7±2.1 m/s, while for the elbow, the failure impact velocity was 19.5±0.9 m/s. An approximate 10% risk of fracture threshold was identified on the modified WorldSID ATD (no flesh analogue included) to inform future protective standards.

RESUMO

BACKGROUND: Increased survival from traumatic injury has led to a higher demand for follow-up care when patients are discharged from hospital. It is currently unclear how follow-up care following major trauma is provided to patients, and how, when, and to whom follow-up services are delivered. The aim of this study was to describe the current follow-up care provided to patients and their families who have experienced major traumatic injury in Australia and New Zealand (ANZ). METHODS: Informed by Donabedian's 'Evaluating the Quality of Medical Care' model and the Institute of Medicine's Six Domains of Healthcare Quality, a cross-sectional online survey was developed in conjunction with trauma experts. Their responses informed the final survey which was distributed to key personnel in 71 hospitals in Australia and New Zealand that (i) delivered trauma care to patients, (ii) provided data to the Australasian Trauma Registry, or (iii) were a Trauma Centre. RESULTS: Data were received from 38/71 (53.5%) hospitals. Most were Level 1 trauma centres (n = 23, 60.5%); 76% (n = 16) follow-up services were permanently funded. Follow-up services were led by a range of health professionals with over 60% (n = 19) identifying as trauma specialists. Patient inclusion criteria varied; only one service allowed self-referral (3.3%). Follow-up was within two weeks of acute care discharge in 53% (n = 16) of services. Care activities focused on physical health; psychosocial assessments were the least common. Most services provided care for adults and paediatric trauma (60.5%, n = 23); no service incorporated follow-up for family members. Evaluation of follow-up care was largely as part of a health service initiative; only three sites stated evaluation was specific to trauma follow-up. CONCLUSION: Follow-up care is provided by trauma specialists and predominantly focuses on the physical health of the patients affected by major traumatic injury. Variations exist in terms of patient selection, reason for follow-up and care activities delivered with gaps in the provision of psychosocial and family health services identified. Currently, evaluation of trauma follow-up care is limited, indicating a need for further development to ensure that the care delivered is safe, effective and beneficial to patients, families and healthcare organisations.

RESUMO

AIM: The aim of this study is to ascertain the role of ultrasonography in appraising the structural intricacies of peripheral nerve pathologies. OBJECTIVES: (1) To scrutinize the anatomy of both normal and abnormal peripheral nerves. (2) Assess different parameters like continuity of the nerve, echotexture, vascularity, cross-sectional area, and thickness of the nerve in various pathologies. METHODS AND MATERIALS: In a prospective observational study conducted at the Department of Radio Diagnosis, Tertiary Care Centre, the study design focused on the examination of 200 cases utilizing a high-resolution 9-14 Mhz and 17 Mhz linear array transducer, integrated into the Aplio 400 Canon Ultrasound System. RESULTS: Among the total cases, 62 were identified as traumatic neuropathy cases, 52 as entrapment neuropathy cases, 14 as infective neuropathy cases, 54 as thermal neuropathy cases, 14 as metabolic neuropathy cases, and 4 as nerve-tumor cases. CONCLUSIONS: In conclusion, this investigation illuminates the dynamic role of ultrasonography as an invaluable diagnostic instrument in appraising peripheral nerve pathologies. The noninvasive attributes, widespread availability, and economic viability of ultrasonography render it a pragmatic choice for clinicians. This inquiry buttresses the escalating significance of ultrasonography within neurology, emphasizing its potential to revolutionize the terrain of peripheral nerve pathology assessment.

RESUMO

The hip is the most common location for avascular necrosis of the femoral head (AVN), with an estimated incidence in the United States of 10,000 to 20,000 new cases per year. The current standard of care for early disease is core decompression, with bone marrow injections becoming more commonplace. Hyperbaric oxygen enhances oxygen delivery to tissue, promotes an anti-inflammatory and pro-healing environment, and helps initiate angiogenesis. We believe that these properties of HBO2 make it a unique tool for AVN and applied it in conjunction with the standard of care for our patient.

RESUMO

Neuroinflammation has a significant impact on different pathologies, such as stroke or spinal cord injury, intervening in their pathophysiology: expansion, progression, and resolution. Neuroinflammation involves oxidative stress, damage, and cell death, playing an important role in neuroplasticity and motor dysfunction by affecting the neuronal connection responsible for motor control. The diagnosis of this pathology is performed using neuroimaging techniques and molecular diagnostics based on identifying and measuring signaling molecules or specific markers. In parallel, new therapeutic targets are being investigated via the use of bionanomaterials and electrostimulation to modulate the neuroinflammatory response. These novel diagnostic and therapeutic strategies have the potential to facilitate the development of anticipatory patterns and deliver the most beneficial treatment to improve patients' quality of life and directly impact their motor skills. However, important challenges remain to be solved. Hence, the goal of this study was to review the implication of neuroinflammation in the evolution of motor function in stroke and trauma patients, with a particular focus on novel methods and potential biomarkers to aid clinicians in diagnosis, treatment, and therapy. A specific analysis of the strengths, weaknesses, threats, and opportunities was conducted, highlighting the key challenges to be faced in the coming years.

RESUMO

Background: Several studies have linked traumatic injury and cardiovascular disease. However, few studies have investigated the associations between traumatic injury and cardiovascular disease subtypes. We aimed to prospectively examine the association between traumatic injury and the risk of incident myocardial infarction (MI) and stroke. Methods: This study was based on a prospective cohort study that included 13,973 patients who had been hospitalized for traumatic injuries from 1980 to 2020. We randomly selected 4 uninjured participants from the cohort study for each patient as controls matched by age ( ± 3 years) and sex. All participants were free of MI and stroke at enrollment. Cox regression was used to examine the association between traumatic injury and incident MI and stroke. Results: During a median follow-up period of 13.5 years, 1032 cases of MI and 4068 cases of stroke were recorded. After multivariable adjustment, relative to controls, patients with severe injury had the highest hazard ratio (HR) for MI (HR = 1.93; 95% CI: 1.26-2.96) and stroke (HR = 1.60; 95% CI: 1.25-2.05). The HRs of MI and stroke were 0.97 (0.81-1.17) and 1.11 (1.02-1.21) for patients with mild injury and 1.28 (0.97-1.69) and 1.22 (1.06 to 1.41) for patients with moderate injury. Additionally, patients with older age at injury and chest injury had a higher HR for MI and stroke (p-interaction < 0.05). Conclusions: Traumatic injury appears to be associated with an increased risk of incident MI and stroke. Therefore, early screening and prevention of MI and stroke following a traumatic injury are needed.

RESUMO

BACKGROUND: Racial/ethnic differences in mental health outcomes after a traumatic event have been reported. Less is known about factors that explain these differences. We examined whether pre-, peri-, and post-trauma risk factors explained racial/ethnic differences in acute and longer-term posttraumatic stress disorder (PTSD), depression, and anxiety symptoms in patients hospitalized following traumatic injury or illness. METHODS: PTSD, depression, and anxiety symptoms were assessed during hospitalization and 2 and 6 months later among 1310 adult patients (6.95% Asian, 14.96% Latinx, 23.66% Black, 4.58% multiracial, and 49.85% White). Individual growth curve models examined racial/ethnic differences in PTSD, depression, and anxiety symptoms at each time point and in their rate of change over time, and whether pre-, peri-, and post-trauma risk factors explained these differences. RESULTS: Latinx, Black, and multiracial patients had higher acute PTSD symptoms than White patients, which remained higher 2 and 6 months post-hospitalization for Black and multiracial patients. PTSD symptoms were also found to improve faster among Latinx than White patients. Risk factors accounted for most racial/ethnic differences, although Latinx patients showed lower 6-month PTSD symptoms and Black patients lower acute and 2-month depression and anxiety symptoms after accounting for risk factors. Everyday discrimination, financial stress, past mental health problems, and social constraints were related to these differences. CONCLUSION: Racial/ethnic differences in risk factors explained most differences in acute and longer-term PTSD, depression, and anxiety symptoms. Understanding how these risk factors relate to posttraumatic symptoms could help reduce disparities by facilitating early identification of patients at risk for mental health problems.

RESUMO

INTRODUCTION: Crises like the COVID-19 pandemic create blood product shortages. Patients requiring transfusions are placed at risk and institutions may need to judiciously administer blood during massive blood transfusions protocols (MTP). The purpose of this study is to provide data-driven guidance for the modification of MTP when the blood supply is severely limited. METHODS: This is a retrospective cohort study of 47 Level I and II trauma centers (TC) within a single healthcare system whose patients received MTP from 2017 to 2019. All TC used a unifying MTP protocol for balanced blood product transfusions. The primary outcome was mortality as a function of volume of blood transfused and age. Hemoglobin thresholds and measures of futility were also estimated. Risk-adjusted analyses were performed using multivariable and hierarchical regression to account for confounders and hospital variation. RESULTS: Proposed MTP maximum volume thresholds for three age groupings are as follows: 60 units for ages 16-30 y, 48 units for ages 31-55 y, and 24 units for >55 y. The range of mortality under the transfusion threshold was 30%-36% but doubled to 67-77% when the threshold was exceeded. Hemoglobin concentration differences relative to survival were clinically nonsignificant. Prehospital measures of futility were prehospital cardiac arrest and nonreactive pupils. In hospital risk factors of futility were mid-line shift on brain CT and cardiopulmonary arrest. CONCLUSIONS: Establishing MTP threshold practices under blood shortage conditions, such as the COVID pandemic, could sustain blood availability by following relative thresholds for MTP use according to age groups and key risk factors.

RESUMO

INTRODUCTION: The objective of this study was to evaluate the performance of the Healthy Aging Brain Care Monitor (HABC-M) as a patient-reported outcome tool to measure cognitive, functional, and psychological symptoms among older adults who sustained non-neurologic injuries requiring hospital admission. METHODS: We used data from a multicenter randomized controlled trial to evaluate the utility of the HABC-M Self-Report version in older patients recovering from traumatic injuries. A total of 143 patients without cognitive impairment were included in the analysis. Cronbach's alpha was used to measure the internal consistency, and Spearman's rank correlation test was used to evaluate the relationship of the HABC-M with standard measures of cognitive, functional, and psychological outcomes. RESULTS: The HABC-M subscales and the total scale showed satisfactory internal consistency (Cronbach's alpha = 0.64 to 0.77). The HABC-M cognitive subscale did not correlate with the Mini-Mental State Examination. The HABC-M functional and psychological subscales correlated with corresponding standard reference measures (|rs| = 0.24-0.59). CONCLUSIONS: The HABC-M Self-Report version is a practical alternative to administering multiple surveys to monitor functional and psychological sequelae in older patients recovering from recent non-neurologic injuries. Its clinical application may facilitate personalized, multidisciplinary care coordination among older trauma survivors without cognitive impairment.

RESUMO

OBJECTIVE: Electrical injury (EI) is a significant, multifaceted trauma often with multi-domain cognitive sequelae, even when the expected current path does not pass through the brain. Chronic pain (CP) research suggests pain may affect cognition directly and indirectly by influencing emotional distress which then impacts cognitive functioning. As chronic pain may be critical to understanding EI-related cognitive difficulties, the aims of the current study were: examine the direct and indirect effects of pain on cognition following EI and compare the relationship between pain and cognition in EI and CP populations. METHOD: This cross-sectional study used data from a clinical sample of 50 patients with EI (84.0% male; Mage = 43.7 years) administered standardized measures of pain (Pain Patient Profile), depression, and neurocognitive functioning. A CP comparison sample of 93 patients was also included. RESULTS: Higher pain levels were associated with poorer attention/processing speed and executive functioning performance among patients with EI. Depression was significantly correlated with pain and mediated the relationship between pain and attention/processing speed in patients with EI. When comparing the patients with EI and CP, the relationship between pain and cognition was similar for both clinical groups. CONCLUSIONS: Findings indicate that pain impacts mood and cognition in patients with EI, and the influence of pain and its effect on cognition should be considered in the assessment and treatment of patients who have experienced an electrical injury.

RESUMO

BACKGROUND: This study investigated the relationship between combat-related traumatic injury (CRTI) and its severity and predicted cardiovascular disease (CVD) risk. MATERIAL AND METHODS: This was an analysis of comparative 10-year predicted CVD risk (myocardial infarction, stroke or CVD-death) using the QRISK®3 scoring-system among adults recruited into the Armed Services Trauma Rehabilitation Outcome (ADVANCE) cohort study. Participants with CRTI were compared to uninjured servicemen frequency-matched by age, sex, rank, deployment (Afghanistan 2003-2014) and role. Injury severity was quantified using the New Injury Severity Score (NISS). RESULTS: One thousand one hundred forty four adult combat veterans were recruited, consisting of 579 injured (161 amputees) and 565 uninjured men of similar age ethnicity and time from deployment/injury. Significant mental illness (8.5% vs 4.4%; p = 0.006) and erectile dysfunction (11.6% vs 5.8%; p < 0.001) was more common, body mass index (28.1 ± 3.9 vs 27.4 ± 3.4 kg/m2; p = 0.001) higher and systolic blood pressure variability (median [IQR]) (1.7 [1.2-3.0] vs 2.1 [1.2-3.5] mmHg; p = 0.008) lower among the injured versus uninjured respectively. The relative risk (RR) of predicted CVD (versus the population expected risk) was higher (RR:1.67 [IQR 1.16-2.48]) among the injured amputees versus the injured non-amputees (RR:1.60 [1.13-2.43]) and uninjured groups (RR:1.52 [1.12-2.34]; overall p = 0.015). After adjustment for confounders CRTI, worsening injury severity (higher NISS, blast and traumatic amputation) were independently associated with QRISK®3 scores. CONCLUSION: CRTI and its worsening severity were independently associated with increased predicted 10-year CVD risk.

RESUMO

OBJECTIVE: Asymmetrical dimensions and nonlinear margins of a multilayered traumatic wound often preclude healing via primary intention. We present the case of an otherwise healthy 21-year-old male who sustained trauma following a boating accident. METHOD: The patient sustained three lacerations to the posterior thighs from the boat propeller. The most extensive wound measured 25×10×6cm of muscle extrusion with a divot fracture involving the posterior femur. RESULTS: Primary closure and restoration of muscle biomechanics was achieved using a combination of a dynamic tissue system (DTS) and porcine urinary bladder matrix (PUBM) xenograft. After 24 days of treatment in hospital, the patient was discharged without the need for home health, outpatient wound care, or ongoing negative pressure wound therapy. The patient recovered full function of the legs and was cleared for participation in all activities. CONCLUSION: This complex traumatic boat propeller injury presented many challenges, including a transverse orientation on the extremity, degree of muscle injury/extrusion, and significant soft tissue loss. The combined application of a DTS with PUBM biological xenograft achieved a primary myocutaneous closure without the need for skin graft or flap reconstruction by plastic surgery.

RESUMO

Major traumatic crush injuries are difficult to manage, with high morbidity, requiring prolonged, complex treatment with many procedures. Free-flap reconstruction is often used yet full functionality still may not be regained. In this case study of a traumatic crush injury of the anterior distal tibia, ankle and foot of a 48-year-old male patient, we opted for an alternative management strategy using a combination of a dynamic tissue system (DTS) and biological xenografts (porcine urinary bladder matrix and a multi-tissue platform). The DTS was kept in place in an outpatient setting for four weeks postoperatively and removed after that time. At the 3-month follow-up, the wound was significantly smaller at about 15% of the original size. The wound healed completely before 6-month follow-up. Our patient's traumatic crush injury was successfully healed using an alternative management strategy, DTS and biologic xenografts.

RESUMO

The blood-brain barrier (BBB) is a multicellular construct that regulates the diffusion and transport of metabolites, ions, toxins, and inflammatory mediators into and out of the central nervous system (CNS). Its integrity is essential for proper brain physiology, and its breakdown has been shown to contribute to neurological dysfunction. The BBB in vertebrates exists primarily through the coordination between endothelial cells, pericytes, and astrocytes, while invertebrates, which lack a vascularized circulatory system, typically have a barrier composed of glial cells that separate the CNS from humoral fluids. Notably, the invertebrate barrier is molecularly and functionally analogous to the vertebrate BBB, and the fruit fly, Drosophila melanogaster, is increasingly recognized as a useful model system in which to investigate barrier function. The most widely used technique to assess barrier function in the fly is the dye-exclusion assay, which involves monitoring the infiltration of a fluorescent-coupled dextran into the brain. In this study, we explore analytical and technical considerations of this procedure that yield a more reliable assessment of barrier function, and we validate our findings using a traumatic injury model. Together, we have identified parameters that optimize the dye-exclusion assay and provide an alternative framework for future studies examining barrier function in Drosophila.

RESUMO

BACKGROUND/AIM: In case of crown fractures after traumatic dental injuries, the affected teeth can be restored either with reattachment of the fractured fragment or with a direct composite restoration. So far, longevity data for reattachments and direct composite restorations with regard to different failure types (pulp necrosis and infection, restoration loss) are scarce. Therefore, the aim of this retrospective study was to evaluate the restorative and biological survival of reattached fragments and composite restorations after crown fractures in permanent teeth. MATERIAL AND METHODS: Dental records of patients treated between 2000 and 2018 were retrospectively analysed regarding the restoration (reattachment or direct composite restorations) of teeth with crown fractures. Survival (no further intervention) and restorative and/or biological failure of all restored teeth were recorded. Statistical analysis was performed using Kaplan-Meier statistics, and the mean annual failure rates for two and 5 years were calculated. Furthermore, the effect of potential risk factors on survival was assessed. Log-rank tests and univariate Cox regression models (likelihood ratio tests) were used to assess the univariate effect of all variables of interest. Variables with a p-value ≤.10 were included in a multivariate Cox regression model with shared frailty (p < .05). RESULTS: Overall, 164 patients with 235 teeth (uncomplicated crown fracture: N = 201, complicated crown fracture: N = 34) were included (1.6 ± 2.5 years observation time). Of these, 59 teeth were restored with reattachment of the fragment and 176 with a composite restoration. Overall, composite restorations had a significantly higher survival rate than reattachments (p = .002). The cumulative survival after 2 years was 42.9% and 65.0% for teeth treated with a reattachment (mAFR = 34.5%) and a composite restoration (mAFR = 19.3%), respectively. When differentiating between failure types, restoration failure and pulp necrosis were significantly more frequently detected in reattached crown fractures compared to composite restorations (restorative failure: p = .001; biological failure: p = .036). In the multivariate Cox regression model, the variable jaw and luxation significantly influenced the survival when the tooth was restored with a composite restoration. The survival was not influenced by the fracture type. CONCLUSIONS: Restorative and biological failures were more frequently detected when the tooth was restored with a reattached fragment compared to a direct composite restoration. Both, restoration failure and pulp necrosis with infection should be considered as frequent complications after restoration of crown-fractured teeth which emphasizes the necessity of regular and short follow-up intervals throughout the first 2 years.

RESUMO

INTRODUCTION: The Victims of Crime Advocacy and Recovery Program (VOCARP) provides advocacy, mental health resources, and educational materials. This study will report complications, readmissions, and recidivism among crime victims, and who used or did not use victim services. MATERIALS AND METHODS: Patients engaged with programming from 3/1/17 until 12/31/18 were included. Control groups were patients injured by violent trauma without VOCARP use (N = 212) and patients injured by unintentional injuries (N = 201). Readmissions, complications, reoperations, and trauma recidivism were reported. RESULTS: 1019 patients (83%) used VOCARP. VOCARP users were less often male (56% vs. 71%), less commonly married (12% vs. 41%), and had fewer gunshot wounds (GSWs, 26% vs. 37%) and sexual assaults (4.1% vs. 8%), all p < 0.05. Of all 1,423 patients, 6.6% had a readmission and 7.4% developed a complication. VOCARP patients had fewer complications (4.5% vs. 13.7%), infections (2% vs. 9%), wound healing problems (1% vs. 3.3%), and deep vein thromboses (0.3% vs. 1.9%), all p < 0.05, but no differences in unplanned operations (4.5%). GSW victims had the most complications, readmissions, and unplanned surgeries. Prior trauma recidivism was frequent among all groups, with crime victim patients having 40% prior violence-related injury (vs 9.0% control, p < 0.0001). Trauma recidivism following VOCARP use occurred in 8.5% (vs 5.7% for non-users, p = 0.16). CONCLUSION: Crime victims differ from other trauma patients, more often with younger age, single marital status, and unemployment at baseline. Complications were lower for VOCARP patients. GSW patients had the most complications, readmissions, and unplanned secondary procedures, representing a population for future attention.

RESUMO

A man in his early 60 s who worked at a waste disposal plant had fallen into the refuse pit and was immediately taken to the emergency department for treatment. After 8 days without recovering consciousness, the man died. Antemortem contrast-enhanced computed tomography at the emergency department indicated Stanford type B/DeBakey type IIIb aortic dissection. The autopsy showed a sharp and transverse intimal tear 0.6 cm in length in the aortic isthmus and fractures in the 5th-6th thoracic vertebrae. No structural abnormalities in arterial walls were noted on histopathological examination. The traumatic aortic dissection induced by falling is rare, compared with vehicle crash. Although the verification process was challenging, the cause of death was ultimately concluded as traumatic aortic dissection due to falling into the refuse pit. The following observations were cited as evidence: (1) the location and feature of the intimal tear, (2) the positional relationship between the impact site and the entry tear, and (3) the circumstance of clash impact onto the "cushion" of accumulated waste in the refuse pit. Inquiries into the cause of death, such as those made in this report, are required to provide detailed information on the circumstances of the accident, postmortem examinations, and careful consideration.
