Incidence and outcomes of delayed intracranial hemorrhage: a population-based cohort study.

Head trauma is a common reason for emergency department (ED) visits. Delayed intracranial hemorrhage (ICH) in patients with minor head trauma is a major concern, but controversies exist regarding the incidence of delayed ICH and discharge planning at the ED. This study aimed to determine the incidence of delayed ICH in adults who developed ICH after a negative initial brain computed tomography (CT) at the ED and investigate the clinical outcomes for delayed ICH. This nationwide population cohort study used data from the National Health Insurance Service of Korea from 2013 to 2019. Adult patients who presented to an ED due to trauma and were discharged after a negative brain CT examination were selected. The main outcomes were the incidence of ICH within 14 days after a negative brain CT at initial ED visit and the clinical outcomes of patients with and without delayed ICH. The study patients were followed up to 1 year after the initial ED discharge. Cox proportional hazard regression analysis was used to estimate the hazard ratio for all-cause 1-year mortality of delayed ICH. During the 7-year study period, we identified 626,695 adult patients aged 20 years or older who underwent brain CT at the ED due to minor head trauma, and 2666 (0.4%) were diagnosed with delayed ICH within 14 days after the first visit. Approximately two-thirds of patients (64.3%) were diagnosed with delayed ICH within 3 days, and 84.5% were diagnosed within 7 days. Among the patients with delayed ICH, 71 (2.7%) underwent neurosurgical intervention. After adjustment for age, sex, Charlson Comorbidity Index, and insurance type, delayed ICH (adjusted hazard ratio, 2.15; 95% confidence interval, 1.86-2.48; p < 0.001) was significantly associated with 1-year mortality. The incidence of delayed ICH was 0.4% in the general population, with the majority diagnosed within 7 days. These findings suggest that patient discharge education for close observation for a week may be a feasible strategy for the general population.

Training injuries in elite men's senior and academy (Super League) rugby league; an analysis of 224,000 exposure-hours.

OBJECTIVES: Report two-years of training injury data in senior and academy professional rugby league. DESIGN: Prospective cohort study. METHODS: Match and training time-loss injuries and exposure data were recorded from two-seasons of the European Super League competition. Eleven/12 (2021) and 12/12 (2022) senior and 8/12 (2021) and 12/12 (2022) academy teams participated. Training injuries are described in detail and overall match injuries referred to for comparison only. RESULTS: 224,000 training exposure hours were recorded with 293 injuries at the senior (mean [95 % confidence interval]; 3 [2-3] per 1000 h) and 268 academy level (2 [2-3] per 1000 h), accounting for 31 % and 40 % of all injuries (i.e., matches and training). The severity of training injuries (senior: 35 [30-39], academy: 36 [30-42] days-lost) was similar to match injuries. Lower-limb injuries had the greatest injury incidence at both levels (senior: 1.85 [1.61-2.12], academy: 1.28 [1.08-1.51] per 1000 h). Head injuries at the academy level had greater severity (35 [25-45] vs. 18 [12-14] days-lost; p < 0.01) and burden (17 [16-18] vs. 4 [4-5] days-lost per 1000 h; p = 0.02) than senior level. At the senior level, the incidence of contact injuries was lower than non-contact injuries (risk ratio: 0.29 [0.09-0.88], p = 0.02). CONCLUSIONS: Training injuries accounted for about a third of injuries, with similar injury severity to match-play. Within training there is a higher rate of non-contact vs. contact injuries. Whilst current injury prevention interventions target matches, these data highlight the importance of collecting high quality training injury data to develop and evaluate injury prevention strategies in training.

Headgear mandates in high school girls' lacrosse: investigating differences in impact rates and game play behaviors.

BACKGROUND/OBJECTIVE: Headgear designed to protect girls' lacrosse athletes is widely available and permitted for voluntary use; however, it remains unknown how policies mandating headgear use may change the sport and, particularly regarding impacts during game-play. Therefore, this study compares the impact rates and game play characteristics of girls' high school lacrosse in Florida which mandates headgear use (HM), with states having no headgear mandate (NHM). MATERIALS AND METHODS: Video from 189 randomly-selected games (HM: 64, NHM: 125) were analyzed. Descriptive statistics, Impact Rates (IR), Impact Rate Ratios (IRR), Impact Proportion Ratios (IPR), and 95% Confidence Intervals (CI) were calculated. IRRs and IPRs with corresponding CIs that excluded 1.00 were deemed statistically significant. RESULTS: 16,340 impacts (HM:5,821 NHM: 10,519; 86.6 impacts/game, CI: 88.6-93.3) were identified using the Lacrosse Incident Analysis Instrument (LIAI). Most impacts directly struck the body (n = 16,010, 98%). A minority of impacts directly struck a player's head (n = 330, 2%). The rate of head impacts was significantly higher in the HM cohort than NHM cohort (IRR = 2.1; 95% CI = 1.7-2.6). Most head impacts (n = 271, 82%) were caused by stick contact in both groups. There was no difference in the proportion of penalties administered for head impacts caused by stick contact between the HM and NHM cohorts (IPR IRRHM/NHM = 0.98; CI = 0.79-1.16). However, there was a significantly greater proportion of head impacts caused by player contact that resulted in a penalty administered in the HM cohort (IPR = 1.44 CI = 1.17-1.54). CONCLUSION: These findings demonstrate that mandating headgear use was associated with a two-fold greater likelihood of sustaining a head impact during game play compared to NHM states. A majority of head impacts in both HM and NHM states were caused by illegal stick contact that did not result in penalty.

High school girls' lacrosse athletes participating in a state with a headgear mandate was twice as likely to sustain a head impact than those participating in states without headgear mandates.Stick contact remains the most common mechanism of head impacts in girls' lacrosse, regardless of mandating headgear.Regardless of whether headgear was or was not mandated, most head impacts caused by stick contact did not result in a penalty.

Emergency Department Evaluation of Young Infants With Head Injury.

OBJECTIVES: We compared the emergency department (ED) evaluation and outcomes of young head-injured infants to older children. METHODS: Using the Pediatric Health Information Systems database, we performed a retrospective, cross-sectional analysis of children <2 years old with isolated head injuries (International Classification of Diseases, 10th Revision, diagnoses) at one of 47 EDs from 2015 to 2019. Our primary outcome was utilization of diagnostic cranial imaging. Secondary outcomes were diagnosis of traumatic brain injury (TBI), clinically important TBI, and mortality. We compared outcomes between the youngest infants (<3 months old) and children 3 to 24 months old. RESULTS: We identified 112 885 ED visits for children <2 years old with isolated head injuries. A total of 62 129 (55%) were by males, and 10 325 (9.1%) were by infants <3 months of age. Compared with older children (12-23 months old), the youngest infants were more likely to: Undergo any diagnostic cranial imaging (50.3% vs 18.3%; difference 31.9%, 95% confidence interval [CI] 35.0-28.9%), be diagnosed with a TBI (17.5% vs 2.7%; difference 14.8%, 95% CI 16.4%-13.2%) or clinically important TBI (4.6% vs 0.5%; difference 4.1%, 95% CI 3.8%-4.5%), and to die (0.3% vs 0.1%; difference 0.2%, 95% CI 0.3%-0.1%). Among those undergoing computed tomography or MRI, TBIs were significantly more common in the youngest infants (26.4% vs 8.8%, difference 17.6%, 95% CI 16.3%-19.0%). CONCLUSIONS: The youngest infants with head injuries are significantly more likely to undergo cranial imaging, be diagnosed with brain injuries, and die, highlighting the need for a specialized approach for this vulnerable population.

Association Between Frailty and Head Impact Location After Ground-Level Fall in Older Adults.

BACKGROUND: Mild traumatic brain injuries (TBIs) are highly prevalent in older adults, and ground-level falls are the most frequent mechanism of injury. OBJECTIVE: This study aimed to assess whether frailty was associated with head impact location among older patients who sustained a ground-level fall-related, mild TBI. The secondary objective was to measure the association between frailty and intracranial hemorrhages. METHODS: We conducted a planned sub-analysis of a prospective observational study in two urban university-affiliated emergency departments (EDs). Patients 65 years and older who sustained a ground-level fall-related, mild TBI were included if they consulted in the ED between January 2019 and June 2019. Frailty was assessed using the Clinical Frailty Scale (CFS). Patients were stratified into the following three groups: robust (CFS score 1-3), vulnerable-frail (CFS score 4-6), and severely frail (CFS score 7-9). RESULTS: A total of 335 patients were included; mean ± SD age was 86.9 ± 8.1 years. In multivariable analysis, frontal impact was significantly increased in severely frail patients compared with robust patients (odds ratio [OR] 4.8 [95% CI 1.4-16.8]; p = 0.01). Intracranial hemorrhages were found in 6.2%, 7.5%, and 13.3% of robust, vulnerable-frail, and severely frail patients, respectively. The OR of intracranial hemorrhages was 1.24 (95% CI 0.44-3.45; p = 0.68) in vulnerable-frail patients and 2.34 (95% CI 0.41-13.6; p = 0.34) in those considered severely frail. CONCLUSIONS: This study found an association between the level of frailty and the head impact location in older patients who sustained a ground-level fall. Our results suggest that head impact location after a fall can help physicians identify frail patients. Although not statistically significant, the prevalence of intracranial hemorrhage seems to increase with the level of frailty.

Trends in mortality rates and correlations between intracranial injuries and external causes: A Japanese population study.

The age-standardized incidence of head trauma in 2016 was 369 per 100,000 people worldwide. The Western Pacific region, including Japan, had the highest incidence. This study aimed to extract ICD-10 code data for intracranial injury (S06) and external causes of morbidity and mortality (V01-Y89), analyze their characteristics and interrelationships, and contribute to these diseases' prevention, treatment, and prognosis. The number of deaths according to injury type and external cause type of intracranial injury published by the Japanese government was statistically analyzed using JoinPoint, and univariate distribution and multivariate correlation were conducted using JMP Software. From 1999-2021, there was a downward trend in the number of deaths because of intracranial injuries: mortality from intracranial injuries was higher among those aged ≥65 years. Conversely, mortality from intracranial injuries was lower among those aged ≤14 years. Among deaths from intracranial injury, mortality from diffuse brain injury and traumatic subdural hemorrhage was more common. Among deaths from external causes of intracranial injury, mortality from falls, transport accidents, and other unforeseen accidents was more common. Mortality because of intracranial injuries increased significantly during the 2011 Great East Japan Earthquake. For some age groups and sexes, there were significant inverse correlations of mortality with traumatic subdural hemorrhage and traumatic subarachnoid hemorrhage for transport accidents, intentional self-harm and assault, and diffuse brain injury and focal brain injury for falls. We believe that the data presented in this study will be useful for preventing and treating intracranial injuries and for developing administrative measures to reduce intracranial injuries.

Health problems among elite Dutch youth long track speed skaters: a one-season prospective study.

OBJECTIVES: To describe the frequency, type, and severity of health problems in long-track speed skating to inform injury prevention strategies. METHODS: We prospectively collected weekly health and sport exposure data on 84 highly trained Dutch athletes aged 15-21 years during the 2019/2020 season using the Oslo Sports Trauma Research Centre questionnaire on Health Problems and the trainers' documentation. We categorised health problems into acute or repetitive mechanisms of injury or illness and calculated incidences (per 1000 sports exposure hours), weekly prevalence and burden (days of time loss per 1000 sports exposure hours) related to the affected body region. RESULTS: We registered 283 health problems (187 injuries, 96 illnesses), yielding an average weekly prevalence of health problems of 30.5% (95% CI 28.7% to 32.2%). Incidence rates were 2.0/1000 hours for acute mechanism injuries (95% CI 1.5 to 2.5) and 3.2/1000 hours for illnesses (95% CI 2.6 to 3.9). For acute mechanism injuries the head, shoulder and lumbosacral region had the highest injury burden of 5.6 (95% CI 4.8 to 6.5), 2.9 (95% CI 2.3 to 3.5) and 2.2 (95% CI 1.7 to 2.8) days of time loss/1000 hours, respectively. For repetitive mechanism injuries, the knee, thoracic spine, lower leg and lumbosacral region had the highest injury burden, with 11.0 (95% CI 9.8 to 12.2), 6.8 (95% CI 5.9 to 7.7), 3.9 (95% CI 3.2 to 4.6) and 2.5 (95% CI 1.9 to 3.1) days of time loss/1000 hours, respectively. CONCLUSION: Our study demonstrated a high prevalence of acute and repetitive mechanism injuries in speed skating. These results can guide future research and priorities for injury prevention.

Head Injury and Risk of Incident Ischemic Stroke in Community-Dwelling Adults.

BACKGROUND: While stroke is a recognized short-term sequela of traumatic brain injury, evidence about long-term ischemic stroke risk after traumatic brain injury remains limited. METHODS: The Atherosclerosis Risk in Communities Study is an ongoing prospective cohort comprised of US community-dwelling adults enrolled in 1987 to 1989 followed through 2019. Head injury was defined using self-report and hospital-based diagnostic codes and was analyzed as a time-varying exposure. Incident ischemic stroke events were physician-adjudicated. We used Cox regression adjusted for sociodemographic and cardiovascular risk factors to estimate the hazard of ischemic stroke as a function of head injury. Secondary analyses explored the number and severity of head injuries; the mechanism and severity of incident ischemic stroke; and heterogeneity within subgroups defined by race, sex, and age. RESULTS: Our analysis included 12 813 participants with no prior head injury or stroke. The median follow-up age was 27.1 years (25th-75th percentile=21.1-30.5). Participants were of median age 54 years (25th-75th percentile=49-59) at baseline; 57.7% were female and 27.8% were Black. There were 2158 (16.8%) participants with at least 1 head injury and 1141 (8.9%) participants with an incident ischemic stroke during follow-up. For those with head injuries, the median age to ischemic stroke was 7.5 years (25th-75th percentile=2.2-14.0). In adjusted models, head injury was associated with an increased hazard of incident ischemic stroke (hazard ratio [HR], 1.34 [95% CI, 1.12-1.60]). We observed evidence of dose-response for the number of head injuries (1: HR, 1.16 [95% CI, 0.97-1.40]; ≥2: HR, 1.94 [95% CI, 1.39-2.71]) but not for injury severity. We observed evidence of stronger associations between head injury and more severe stroke (National Institutes of Health Stroke Scale score ≤5: HR, 1.31 [95% CI, 1.04-1.64]; National Institutes of Health Stroke Scale score 6-10: HR, 1.64 [95% CI, 1.06-2.52]; National Institutes of Health Stroke Scale score ≥11: HR, 1.80 [95% CI, 1.18-2.76]). Results were similar across stroke mechanism and within strata of race, sex, and age. CONCLUSIONS: In this community-based cohort, head injury was associated with subsequent ischemic stroke. These results suggest the importance of public health interventions aimed at preventing head injuries and primary stroke prevention among individuals with prior traumatic brain injuries.

Incidence of intraoperative hypotension and its factors among adult traumatic head injury patients in comprehensive specialized hospitals, Northwest Ethiopia: a multicenter observational study.

INTRODUCTION: Traumatic head injury (THI) poses a significant global public health burden, often contributing to mortality and disability. Intraoperative hypotension (IH) during emergency neurosurgery for THI can adversely affect perioperative outcomes, and understanding associated risk factors is essential for prevention. METHOD: A multi-center observational study was conducted from February 10 to June 30, 2022. A simple random sampling technique was used to select the study participants. Patient data were analyzed using bivariate and multivariate logistic regression to identify significant factors associated with intraoperative hypotension (IH). Odds ratios with 95% confidence intervals were used to show the strength of association, and P value < 0.05 was considered as statistically significant. RESULT: The incidence of intra-operative hypotension was 46.41% with 95%CI (39.2,53.6). The factors were duration of anesthesia ≥ 135 min with AOR: 4.25, 95% CI (1.004,17.98), severe GCS score with AOR: 7.23, 95% CI (1.098,47.67), intracranial hematoma size ≥ 15 mm with AOR: 7.69, 95% CI (1.18,50.05), and no pupillary abnormality with AOR: 0.061, 95% CI (0.005,0.732). CONCLUSION AND RECOMMENDATION: The incidence of intraoperative hypotension was considerably high. The duration of anesthesia, GCS score, hematoma size, and pupillary abnormalities were associated. The high incidence of IH underscores the need for careful preoperative neurological assessment, utilizing CT findings, vigilance for IH in patients at risk, and proactive management of IH during surgery. Further research should investigate specific mitigation strategies.

A Comparison of Maxillofacial and Head Injuries Following Electric Scooter and Bicycle Accidents.

BACKGROUND: The prevalence of maxillofacial and head injuries associated with electric scooters (e-scooter, ES) has risen in concordance with its popularity. PURPOSE: The purpose of this study was to compare maxillofacial and head injury location, type, and severity related to ES and bicycle accidents and to identify factors contributing to injury severity. STUDY DESIGN, SETTING, SAMPLE: The authors implemented a multicenter retrospective cohort study in Seattle, Washington, and enrolled a sample of ES riders and bicyclists who sustained maxillofacial injuries between September 2020 and September 2022. The exclusion criteria included nonmotorized scooters, motorized bicycles, injuries with other operators, or vehicles, and pre-evaluation deaths. PREDICTOR VARIABLE: The predictor variable was vehicle type, bicycle or ES. OUTCOME VARIABLES: The outcome variables included maxillofacial injury location, distinguished by horizontal facial thirds and injury type, defined as hard or soft tissue. Associated head injury types were also reported as hard (calvaria) or soft (scalp) tissue injuries. The severity of these injuries was quantified using both the injury severity score and the face and head abbreviated injury scale. COVARIATES: Demographic, injury, and treatment-related variables were collected. ANALYSES: Bivariate, multivariate, and regression statistics were computed. Statistical significance was P < .05. RESULTS: The final sample was composed of 205 total subjects, of which 52 (25.4%) were in the ES group and 153 (74.6%) in the bicycle group. Isolated midface injuries were the most common hard tissue location in the ES (15.4%) and bicycle (29.4%) groups. The most common soft tissue injury location included the upper face and midface in the ES group (19.2%) and the midface in the bicycle group (22.9%). Both hard and soft tissue head injuries were more prevalent in the ES group (P < .0002 and P < .0001). Moreover, intracranial injuries were seen in 36.5% of ES subjects compared to 9.8% bicycle subjects (P < .0001). Between the two groups there was no difference in maxillofacial injury severity, but head injuries were more severe in the ES group (P < .0002). Using regression analysis, drug use was found to have a significant impact on the mean injury severity score (P < .002) and helmet use did not have significant impact on face or head injury severity. CONCLUSION: Maxillofacial injury location, type, and severity are comparable among ES and bicycles. However, ES riders are at greater risk of severe head injuries compared to bicycles, and riding while intoxicated has the greatest effect on injury severity.

The incidence and patterns of maxillofacial fractures and associated head and neck injuries.

The aim of this study was to evaluate the incidence and patterns of maxillofacial fractures and the demographic characteristics of associated head and neck injuries. This single-center retrospective cohort study was conducted at the Department of Oral and Maxillofacial Surgery of King Abdullah University Hospital (KAUH) in Irbid, northern Jordan. The data was obtained from the electronic clinical records of all patients in whom maxillofacial fractures and associated head and neck injuries were confirmed. During the five-year period captured by this retrospective study, 481 patients with 1026 maxillofacial fractures (equivalent to 2.13 fractures per patient) were treated. The sample comprised of 369 (76.7%) males and 112 (23.3%) females, resulting in a male/female ratio of 3.3:1. Majority of the patients were in the 21-30 age group and RTA was the most common cause of maxillofacial fractures, accounting for 299 (62.1%) of the analyzed cases. In 316 cases, maxillary fractures were accompanied by associated injuries, 132 (41.77%) of which were intracranial lesions, 80 (25.32%) were skull fractures, and 59 (18.67%) were cervical spine injuries. Based on the obtained data, it can be concluded that the high occurrence of RTA emphasizes the significance of adhering to traffic laws and regulations, as individuals who have suffered serious head and neck injuries as a result of maxillofacial trauma may experience potentially fatal consequences. Thus, management for patients with maxillofacial fractures and concomitant traumas should be multidisciplinary and coordinated.

Risk factors for clinically important traumatic brain injury in minor head injury in older people.

BACKGROUND AND OBJECTIVES: The incidence of traumatic brain injury (TBI) in older individuals is increasing with an increase in the older population. For older people, the required medical interventions and hospitalization following minor head injury have negative impacts, which have not been reported in literature up till now. We aimed to investigate the risk factors for clinically important traumatic brain injury (ciTBI) in older patients with minor head injury. METHODS: This is a retrospective single-center cohort study. Older patients aged ≥65 years presenting with head injury and a Glasgow Coma Scale (GCS) score of ≥13 upon arrival at the hospital between January 1, 2018, and October 31, 2021, were included. Patients with an injury duration of ≥24 h were excluded. The primary outcome was defined as ciTBI (including death, surgery, intubation, medical interventions, and hospital stays of ≥2 nights). Multiple logistic regression analysis was conducted to identify the risk factors. RESULTS: A total of 296 patients were included initially, and 6 of them were excluded subsequently. ciTBI was identified in 62 cases. According to the results of the multiple logistic regression analysis, GCS scores of ≤14 (OR 3.72, 95% CI 1.89-7.30), high-risk mechanisms of injury (OR 2.80, 95% CI 1.39-5.64), vomiting (OR 5.01, 95% CI 1.19-21.1), and retrograde amnesia (OR 6.90, 95% CI 3.37-14.1) were identified as risk factors. CONCLUSION: In older patients with minor head injury, GCS ≤14, high-risk mechanisms of injury, vomiting, and retrograde amnesia are risk factors for ciTBI.

Head Protection Device for Individuals at Risk for Head Injury due to Ground-Level Falls: Single Trauma Center User Experience Investigation.

BACKGROUND: Falls represent a large percentage of hospitalized patients with trauma as they may result in head injuries. Brain injury from ground-level falls (GLFs) in patients is common and has substantial mortality. As fall prevention initiatives have been inconclusive, we changed our strategy to injury prevention. We identified a head protection device (HPD) with impact-resistant technology, which meets head impact criteria sustained in a GLF. HPDs such as helmets are ubiquitous in preventing head injuries in sports and industrial activities; yet, they have not been studied for daily activities. OBJECTIVE: We investigated the usability of a novel HPD on patients with head injury in acute care and home contexts to predict future compliance. METHODS: A total of 26 individuals who sustained head injuries, wore an HPD in the hospital, while ambulatory and were evaluated at baseline and 2 months post discharge. Clinical and demographic data were collected; a usability survey captured HPD domains. This user experience design revealed patient perceptions, satisfaction, and compliance. Nonparametric tests were used for intragroup comparisons (Wilcoxon signed rank test). Differences between categorical variables including sex, race, and age (age group 1: 55-77 years; age group 2: 78+ years) and compliance were tested using the chi-square test. RESULTS: Of the 26 patients enrolled, 12 (46%) were female, 18 (69%) were on anticoagulants, and 25 (96%) were admitted with a head injury due to a GLF. The median age was 77 (IQR 55-92) years. After 2 months, 22 (85%) wore the device with 0 falls and no GLF hospital readmissions. Usability assessment with 26 patients revealed positive scores for the HPD post discharge regarding satisfaction (mean 4.8, SD 0.89), usability (mean 4.23, SD 0.86), effectiveness (mean 4.69, SD 0.54), and relevance (mean 4.12, SD 1.10). Nonparametric tests showed positive results with no significant differences between 2 observations. One issue emerged in the domain of aesthetics; post discharge, 8 (30%) patients had a concern about device weight. Analysis showed differences in patient compliance regarding age (χ12=4.27; P=.04) but not sex (χ12=1.58; P=.23) or race (χ12=0.75; P=.60). Age group 1 was more likely to wear the device for normal daily activities. Patients most often wore the device ambulating, and protection was identified as the primary benefit. CONCLUSIONS: The HPD intervention is likely to have reasonably high compliance in a population at risk for GLFs as it was considered usable, protective, and relevant. The feasibility and wearability of the device in patients who are at risk for GLFs will inform future directions, which includes a multicenter study to evaluate device compliance and effectiveness. Our work will guide other institutions in pursuing technologies and interventions that are effective in mitigating injury in the event of a fall in this high-risk population.

Analysis of Neurosurgical Injuries and The Lessons Learned After the Catastrophic Double Earthquakes in Turkey.

AIM: To identify the patterns and types of neuorosurgical injuries sustained by victims of the double earthquakes affected ten cities with a population of 15 million in southern and central Türkiye. MATERIAL AND METHODS: In this descriptive observational study, we retrospectively analyzed the medical records of a university hospital located in one of the ten cities affected by the earthquake. RESULTS: A total of 1,612 patients with earthquake-related injuries were admitted during the study period, of which 139 (8.6%) had neurosurgical injuries. The mean age of the patients was 42.4 ± 21.1 years (median, 42 years), and 53.2% of them were female. Of the 139 patients with neurosurgical injuries, 41 (29.5%) had craniocerebral injuries, 95 (68.3%) had spinal injuries, and three (2.2%) had both craniocerebral and spinal injuries. A total of 31 surgeries were performed (22.3%) (five [3.6%] for craniocerebral injuries and 26 [18.7 %] for spinal injuries). Ninety-eight patients (70.5%) had concomitant systemic traumas. The overall mortality rate was 5.75%, with crush syndrome (n=4, 50%), being the leading cause of death, followed by neurosurgical pathologies (n=3, 37.5%) and pneumonia with septic shock (n=1, 12.5%). CONCLUSION: Neurosurgical injury is an important cause of post-earthquake mortality and morbidity. To ensure efficient medical rescue and judicious resource allocation, it is essential to recognize the characteristics of earthquake-related neurosurgical injuries. This study provides valuable information regarding the incidence, characteristics, and outcomes of neurosurgical injuries in earthquake-affected patients. Our findings highlight the need for prompt diagnosis and management of such injuries, particularly in those with concomitant systemic trauma.

Bicycle-related accidents in Rome: Investigating clinical patterns, demographics, injury contexts, and health outcomes for enhanced public safety.

INTRODUCTION: This study aims to analyze the clinical characteristics, demographic features, and injury circumstances of patients admitted to the Emergency Department (ED) at Fondazione Policlinico Universitario A. Gemelli (IRCCS) in Rome, Italy, due to bicycle accidents. METHODS: Data on clinical characteristics, accident timing, injury circumstances, and helmet use were collected for ED patients involved in bicycle accidents from January 2019 to December 2022. Subsequently, Abbreviated Injury Scale codes of all diagnoses were recorded and the Injury Severity Score was calculated. RESULTS: Over the study period, 763 patients were admitted to the ED following bicycle accidents, with a 0.3 % fatality rate and a 30.4 % frequency of multitrauma. Multivariate analysis revealed that collisions with other vehicles increased trauma severity and the risk of ICU admission. Conversely, helmet use was associated with reduced severity of head trauma and a lower likelihood of ICU admission. Notably, toxicological investigations were not conducted for any ED-admitted patients. CONCLUSIONS: Although a low mortality rate and a low incidence of multi-trauma have been shown in comparison to other nations, it is necessary to adopt prevention strategies like safety devices, more cycle paths, and better infrastructures on the one hand, and stricter laws on the other. It is essential to require toxicological testing in Italy for all accidents involving this means of transport, and to make helmet use compulsory for all ages.

Epidemiology and patterns of gymnastics-related head & neck trauma injuries: A NEISS database study.

OBJECTIVE: To describe the epidemiology and patterns of gymnastics-related Head & Neck trauma injuries using the NEISS database from 2001 to 2020. STUDY DESIGN AND SETTING: Cross-sectional analysis of a national database. METHODS: Gymnastics-related ED visits between 2001 and 2020 were queried from the NEISS database. Bivariate chi-squared analyses were used to compare injury demographics, location, type, and disposition. Fracture location was identified using the narrative description of each case and were divided into subtypes for further analysis. RESULTS: 1455 gymnastics-related head and neck traumatic injuries were identified. The majority were in females (65.8%). The most common presenting age group was pediatric (≤18 years) (92.7%), and the largest racial group was Caucasian (51.5%). Of all location subtypes, facial injuries were the most common presenting injury type overall (45.2%). Regarding injury types, lacerations were most common (36.8%), followed by dental injury (30.7%) and fractures (21.2%). The most common location of head and neck fractures was the nose (45.8%), followed by cervical spine (16.7%) and orbit (13.3%). The majority (95.7%) of gymnastics-related head and neck traumatic injuries presenting to the ED were treated and discharged. CONCLUSION: This study characterizes gymnastics-related head and neck injuries which is a topic that is under-studied. The findings from this study are helpful for gymnasts and those who care for them including providers, coaches and guardians, and this data may help inform future guidelines for treatment and injury prevention.

Examining the relationship between head trauma and opioid use disorder: A systematic review.

OBJECTIVE: To examine recent literature and determine common clinical risk factors between antecedent traumatic brain injury (TBI) and the following development of opioid misuse and provide a framework for clinical identification of at-risk subjects and evaluate potential treatment implications within this association. DESIGN: A comprehensive systematic literature search of PubMed was conducted for articles between 2000 and December 2022. Studies were included if the human participant had any head trauma exposure and any chronic opioid use or dependence. After eligibility criteria were applied, 16 studies were assessed for thematic trends. RESULTS: Opioid use disorder (OUD) risks are heightened in cohorts with head trauma exposed to opioids while in the hospital, specifically with tramadol and oxycodone. Chronic pain was the most common predictor of long-term OUD, and continuous somatic symptoms associated with the TBI can lead to long-term opioid usage. Individuals who present with coexisting psychiatric conditions pose significantly more risk associated with a higher risk of long-term opioid use. CONCLUSION: Findings indicate that therapists and clinicians must consider a risk profile for persons with TBI and follow an integrated care approach to account for mental health, prior substance misuse, presenting somatic symptoms, and current medication regimen during evaluation.

Injury Patterns of Electric-Scooter Related Trauma: A Systematic Review With Proportion Meta-Analysis.

Electric scooter (ES)-related injuries are increasing but poorly described. Clinicians need more information to be prepared for these patients. We supposed two prevalent patterns of patients: mildly injured (predominant upper-limb injuries) and severely injured (predominant head trauma). This study aims to understand the frequency of ES-related injuries and patients' characteristics despite the heterogeneity of data currently available. A systematic review with a proportion meta-analysis was conducted on studies with a multidisciplinary description of ES-related injuries in adult patients (PROSPERO-ID: CRD42022341241). Articles from inception to April 2023 were identified in MEDLINE, Embase, and Cochrane's databases. The risk of bias was evaluated using ROBINS-I. Twenty-five observational studies with 5387 patients were included in the meta-analysis, depending on reported data. Upper-limb (31.8%) and head (19.5%) injuries are the most frequent (25/25 studies included). When injured while riding, 19.5% of patients are intoxicated with drugs/alcohol, and only 3.9% use a helmet, increasing the possibility of severe injuries. About 80% of patients are victims of spontaneous falls. Half of the patients self-present to the ED, and 69.4% of cases are discharged directly from the ED. Studies' limitations include an overall moderate risk of bias and high heterogeneity. Electric scooter-related accidents are commonly associated with upper-limb injuries but often involve the head. Spontaneous falls are the most common mechanism of injury, probably related to frequent substance abuse and helmet misuse. This hot topic is not adequately investigated due to a lack of data. A prospective registry could fill this gap.

Abusive head trauma: The body of the iceberg - A population-based survey on prevalence and perpetrators.

BACKGROUND: Research on abusive head trauma (AHT) is usually research on clinically identified cases, while population-based studies, having the potential to identify cases of shaking that did not end with hospital admission, are missing to date. OBJECTIVE: Thus, we aimed to assess the prevalence of AHT and associated risk factors in a representative sample of the German population. PARTICIPANTS AND SETTING: We conducted a cross-sectional, observational study in Germany from July to October 2021. Using different sampling steps including a random route procedure, a probability sample of the German population was generated. The final sample consisted of 2503 persons (50.2 % female, mean age: 49.5 years). METHODS: Participants were asked about sociodemographic information in a face-to-face interview and whether they had been ever responsible for the care of an infant and whether they had ever performed potential harmful methods including shaking to calm it, intimate partner violence (IPV) and adverse childhood experiences (ACEs) using a questionnaire. RESULTS: In total, 1.4 % of women (N = 18) and 1.1 % of men (N = 13) reported to have at least once shaken an infant to calm it. Ever having used a potential harmful parenting method in calming an infant was reported by 4.9 % of women (N = 61) and 3.1 % (N = 39) of men. No gender differences were seen. A low income, living with someone under 16 in the household and victimization and perpetration of IPV and ACEs are associated with increased risks of shaking and other potential harmful methods to calm an infant. CONCLUSIONS: Our data suggest that despite better knowledge on the dangers of shaking, the percentage of women that shake infants might be higher than previously thought. Also, intimate partner violence and ACEs are key risk factor for shaking and harmful parenting behaviors in general. This has important implications for future prevention programs.

The epidemiological characteristics of pediatric head injury in Hangzhou, China: a retrospective study based on cranial CT examinations.

PRIMARY OBJECTIVE: This study aims to create a pediatric head injury database based on cranial CT examinations and explore their epidemiologic characteristics. METHODS: Data related to cranial CT examinations of pediatric head injuries from March 2014 to March 2021 were collected at outpatient and emergency department of a pediatric medical center. The causes of injury, observable post-injury symptoms, and cranial injury findings were extracted with the assistance of natural language processing techniques. RESULTS: Reviewing the data from records on 52,821 children with head injuries over a period of 7 years, the most common causes of pediatric head injury were falls (58.3%), traffic accidents (26.0%), smash/crush/strike (13.9%), violence (1.5%) and sports-related incidents (0.3%). Overall, most of those injured were boys which accounting for 62.2% of all cases. Skull fractures most commonly occur in the parietal bone (9.0%), followed by the occipital (5.2%), frontal (3.3%) and temporal bones (3.0%). Most intracranial hemorrhages occurred in epidural (5.8%), followed by subdural (5.1%), subarachnoid (0.9%), intraparenchymal (0.5%) and intraventricular (0.2%) hemorrhages. Spring and autumn showed more events than any other season. CONCLUSIONS: To the best of our knowledge, this is the largest sample of epidemiological study of head injury in the Chinese pediatric population to date.
