Analyzing the Prevalence of and Factors Associated with Road Traffic Crashes (RTCs) among Motorcyclists in Bangladesh.

Methods: A cross-sectional survey was conducted using a structured questionnaire involving 402 motorcyclists from four major southeastern towns, comprising 350 (86.07%) males and 52 (12.93%) females. The chi-square test was applied in bivariate analysis, and binary multivariable logistic regression was performed to determine the risk factors of road traffic crashes. Results: This study's findings revealed that the overall reported prevalence of road traffic crashes involving motorcycle drivers over one year was 68.66%. Multivariable logistic regression analysis revealed several factors that significantly impacted road traffic crashes. These factors included driving without a valid driving license, the young age (<20) of motorcyclists, driving in rainy weather, exceeding the speed limit, per-week working hours, smoking status, motorcycle ownership, the brand of motorcycle, and not wearing a helmet while driving. Conclusion: The study findings highlight the need for improving motorcycle safety by implementing measures such as imposing per-week work hour limits for riders, enforcing traffic regulations, and promoting helmet use among motorcycle drivers. The results of this study draw attention to the Bangladesh Road Transport Authority (BRTA) and motorcycle drivers in the country to decrease motorcycle crashes and the severity of injuries by implementing efficient guidelines and strategies for driving motorcycles. The findings of this study can assist policymakers and concerned authorities in taking the essential steps to lessen road traffic crashes among motorcyclists in Bangladesh.

Feasibility of Customized Thermoplastic Patient-Specific Helmet Bolus for Scalp Irradiation Using Volumetric-Modulated Arc Therapy Planning.

Introduction: In this study, we sought to develop a thermoplastic patient-specific helmet bolus that could deliver a uniform therapeutic dose to the target and minimize the dose to the normal brain during whole-scalp treatment with a humanoid head phantom. Methods: The bolus material was a commercial thermoplastic used for patient immobilization, and the holes in the netting were filled with melted paraffin. We compared volumetric-modulated arc therapy treatment plans with and without the bolus for quantitative dose distribution analysis. We analyzed the dose distribution in the region of interest to compare dose differences between target and normal organs. For quantitative analysis of treatment dose, OSLD chips were attached at the vertex (VX), posterior occipital (PO), right (RT), and left temporal (LT) locations. Results: The average dose in the clinical target volume was 6553.8 cGy (99.3%) with bolus and 5874 cGy (89%) without bolus, differing by more than 10% from the prescribed dose (6600 cGy) to the scalp target. For the normal brain, it was 3747.8 cGy (56.8%) with bolus and 5484.6 cGy (83.1%) without bolus. These results show that while the dose to the treatment target decreased, the average dose to the normal brain, which is mostly inside the treatment target, increased by more than 25%. With the bolus, the OSLD measured dose was 102.5 ± 1.2% for VX and 101.5 ± 1.9%, 95.9 ± 1.9%, and 81.8 ± 2.1% for PO, RT, and LT, respectively. In addition, the average dose in the treatment plan was 102%, 101%, 93.6%, and 80.7% for VX, PO, RT, and LT. When no bolus was administered, 59.6 ± 2.4%, 112.6 ± 1.8%, 47.1 ± 1.6%, and 53.1 ± 2.3% were assessed as OSLD doses for VX, PO, RT, and LT, respectively. Conclusion: This study proposed a method to fabricate patient-specific boluses that are highly reproducible, accessible, and easy to fabricate for radiotherapy to the entire scalp and can effectively spare normal tissue while delivering sufficient surface dose.

Neurocognitive outcomes and associated clinical factors 5 years after surgery in children with craniosynostosis.

OBJECTIVE: Craniosynostosis involves early closure of one or more sutures, which is known to limit normal cranium growth and interfere with normal brain development. Various surgical methods are used, ranging from minimally invasive strip craniectomy to more extensive whole-vault cranioplasty. This study aimed to evaluate neurocognitive outcomes 5 years after surgical treatment in children with craniosynostosis and to evaluate relevant clinical factors. METHODS: After exclusion of genetically confirmed syndromic craniosynostosis patients, a retrospective review was conducted on 112 nonsyndromic craniosynostosis patients who underwent surgical treatment and follow-up neurocognitive assessment. Ninety-seven patients underwent strip craniectomy with postoperative orthotic helmet therapy, and 15 received other surgical treatment: 4 with distraction osteotomy and 11 with craniofacial reconstruction. Neurocognitive assessment using the Korean Wechsler Preschool and Primary Scale of Intelligence, Fourth Edition (K-WPPSI-IV), was performed 5 years postoperatively. Clinical factors were assessed regarding neurocognitive outcomes. RESULTS: The mean age at surgery was significantly younger in the strip craniectomy group (strip craniectomy 4.6 months vs other surgical treatment 18.6 months, p < 0.01). Patients with 2 or more sutures involved were more likely to receive more extensive surgical treatment (16.5% in the strip craniectomy group vs 53.8% in the other group, p < 0.01). Four (3.5%) patients who showed evidence of increased intracranial pressure (ICP) also underwent more extensive surgical treatment. Multivariable linear regression revealed a significant correlation of age at neurocognitive testing (-3.18, 95% CI -5.95 to -0.40, p = 0.02), increased ICP (-34.73, 95% CI -51.04 to -18.41, p < 0.01), and the level of maternal education (6.11, 95% CI 1.01-11.20, p = 0.02) with the Full-Scale Intelligence Quotient (FSIQ). Age at surgery, involvement of 2 or more sutures, and type of operation demonstrated no correlation with FSIQ. Among the 97 patients who underwent strip craniectomy, the FSIQ ranged from mean ± SD 100.2 ± 10.2 (bicoronal) to 110.1 ± 12.7 (lambdoid), and there was no significant difference between the suture groups (p = 0.41). The 5 index scores were all within average ranges based on their age norms. CONCLUSIONS: Age at neurocognitive assessment, increased ICP, and maternal education level showed significant correlations with the neurocognitive function of craniosynostosis patients. Although children with craniosynostosis exhibited favorable 5-year postoperative neurocognitive outcomes across various synostosis sutures, longer follow-up is needed to reveal the incidence of neurocognitive dysfunction in these patients.

Analysis of increased motorcycle accidents during the COVID-19 pandemic: a single-center study from Türkiye.

BACKGROUND: The Coronavirus Disease 2019 (COVID-19) pandemic has led to a unique set of circumstances, straining health-care systems and affecting the way of life in societies around the world. Measures such as social isolation, travel restrictions, and workplace closures have led to an increase in motorcycle use. Consequently, motorcycle accidents have become a significant problem during this period. This study presents detailed research conducted to examine motorcycle accidents during the COVID-19 pandemic and to understand the causes and consequences of the increase in these accidents. METHODS: This research evaluated records from a single health examination and used various models to analyze motorcycle acci-dents within a specified time period. Additionally, retrospective analyses were conducted to examine associations between motorcycle use and crashes in our country before and after the pandemic. The records of 386 patients who were injured in motorcycle accidents and followed up, received treatment, and were recorded at Biruni University Hospital between November 2015 and April 2023 were retrospectively examined. Noted details included the victims' age, gender, injury mechanism, injury site, injury severity, helmet use, presence and location of fractures, time distribution of the accident, and the severity of other important tissue injuries. The relationship between the injury site, fractures, and accident details, and the "Injury Severity Score" (ISS) was also investigated. RESULTS: Among the 386 injured victims in motorcycle accidents, 333 were male and 53 were female. Of these, 168 (43.5%) were motorcycle drivers, 137 (35.5%) were motorcycle couriers, and 81 (21%) were pedestrians. A total of 186 (48%) injuries occurred before the pandemic (November 2015-March 2020), while 200 (52%) were sustained during the pandemic. The study indicates a noticeable increase in motorcycle injuries, particularly among motor couriers, especially during the pandemic quarantine periods. Post hoc analysis revealed that motor couriers had significantly lower ISS compared to other professions (p=0.009 and p=0.045, respectively). Motorcyclists who wore helmets were found to have significantly lower ISS than those who did not wear helmets (p<0.05). Furthermore, it was found that the ISS was positively correlated with the number of bone fractures, total soft tissue injury, and significant clinical characteristics (r=0.758, r=0.756, and p<0.001, respectively). CONCLUSION: This clinical study's findings demonstrate that the measures implemented during the pandemic to limit society's mobility have led to an increase in motorcycle accidents. Notably, there has been a significant rise in the number of accidents, particularly involving individual motorcycle use and motorcycle courier services.

Maxillofacial trauma caused by e-scooters: a retrospective review prior to the extension of the UK scheme.

The nationwide extension of the electric scooter (e-scooter) scheme, which began in 2020, aimed to alleviate public transport congestion, to reduce pollution and peak-time road traffic. This retrospective study evaluates the range of e-scooter-related maxillofacial trauma before the recent scheme extension and compares the findings with existing literature on this topic. The Queen Elizabeth Hospital Birmingham, United Kingdom (UK) operates as a Level 1 Regional Major Trauma Centre and serves a population of four million. All patient records between September 2021 to September 2022 were analysed to establish the types of e-scooter-related maxillofacial trauma sustained. A Pearson's chi-squared test was used to assess for significant associations between variables recorded. Falls accounted for the majority of injuries (44.3%), and soft tissue lacerations were the most common maxillofacial injury (38%). Statistically significant results were measured in the following variables: gender and intoxication status (p = 0.007), helmet status and injuries sustained in maxillofacial and non-maxillofacial regions (p = 0.043), mechanism of injury and injuries sustained in both the maxillofacial and non-maxillofacial regions (p = 0.045). E-scooters are an emerging concern within the UK. Further studies across the UK are required to assess the frequency of e-scooter-related injuries. Such data may prove useful in determining the government's decision on e-scooter use on UK roads.

Effect of helmet use on maxillofacial injuries due to bicycle and scooter accidents: a systematic literature review and meta-analysis.

Maxillofacial injury is a common injury resulting from bicycle (including e-bike) and scooter accidents. With 80,000 admissions to emergency departments in 2019, bicycle accidents account for more than half of all traffic-related emergency department visits in the Netherlands. The United States reports approximately 130,000 injuries and 1000 fatalities related to cycling annually. This systematic review and meta-analysis was performed to examine the protective effect of helmets against maxillofacial injuries resulting from bicycle and scooter (including e-bike and e-scooter) accidents. After a systematic literature search, 14 studies were found to be eligible for this systematic review. Of these, 11 were included in the meta-analysis. None of the included studies focused on vehicles with motors (e-bikes and e-scooters); all focused only on non-motorized vehicles. All included studies were non-randomized, which could have led to bias in the pooled results. Data from the included studies were tested for heterogeneity using the binary random-effects model (DerSimonian-Laird method), and the odds ratio for the occurrence of maxillofacial injury in cyclists wearing a helmet versus those not wearing a helmet was calculated by random-effects meta-analysis. Patients who had worn a helmet suffered significantly fewer maxillofacial injuries than patients who had not, in bicycle accidents (odds ratio 0.682). In conclusion, wearing a helmet has a significant protective effect against maxillofacial injury, indicating the need for strict helmet legislation.

The impact of electric scooters in Melbourne: data from a major trauma service.

BACKGROUND: The proliferation of electric scooters globally has been associated with an increase in related injuries and consequent economic burden. This study aims to assess the injury patterns and the economic impact associated with electric scooter use in Melbourne, Australia. METHODS: A retrospective cohort study was conducted using hospital and registry data from January 2022 to January 2023. Data collected included demographic details, alcohol and helmet use, injury type and severity, operative treatment provided, and direct medical costs. The economic impact (in AUD) of the patient's emergency presentation and hospital admission was calculated. RESULTS: During the study period, 256 electric scooter related injuries were recorded, comprising 247 riders and nine pedestrians. The majority of patients were males (69%) with a median age of 29.5 (15-78). Alcohol use was reported by 34% and helmet use by 33%. Injuries most commonly affected the upper limb (53%) and head (50%), with abrasions (75%) and fractures (48%) being the most common type of injury sustained. The total hospital cost was $1 911 062, and the median cost was $1321.66 per patient (IQR: $479.37-$5096.65). CONCLUSION: Electric scooter usage, as observed through patient presentations to the Royal Melbourne Hospital, is associated with a considerable number of injuries, primarily among young males, and an ensuing substantial economic burden. The findings underscore the urgent need for improved safety measures to minimize electric scooter-related injuries and their clinical and economic repercussions.

Endoscopy-Assisted Craniosynostosis Surgery without Postoperative Helmet Molding Therapy.

OBJECTIVE: Endoscopy-assisted craniosynostosis surgery (EACS) yields excellent surgical outcomes by minimizing blood loss, operative time, and hospital stays. Postoperative helmet therapy (PHT), commonly employed for head shape correction, involves frequent adjustments, potential complications, and high costs. Given the rising cost of helmet therapy, reduced insurance coverage, and limited availability in low- and middle-income countries, understanding success rates without helmet use is crucial. The present study analyses the anthropometric results of the first EACS series without PHT. METHODS: A retrospective analysis of a single-center series involving 90 consecutive patients who underwent EACS without PHT from 2012 to 2022 was conducted, with a follow-up exceeding 3 years. The study exclusively included patients with nonsyndromic isolated sagittal synostosis, with 33 meeting the criteria. Craniometric measurements were obtained from preoperative, 1-year postoperative, and the latest computed tomography scans. For isolated sagittal synostosis cases, the cephalic index (CI) was calculated (CI >75 for excellent results, CI 70-75 for good results, and <70 for poor results). Collected data encompassed patient sex, age, and follow-up time. RESULTS: The mean age was 84.8 ± 45.3 days (2.79 ± 1.49 months) within a range of 3-172 days. The preoperative mean CI was 68 ± 42, increasing to 76 ± 6 1 year postoperatively (mean difference +8 ± 6.3; P = 0.0001). Seventy-one percent of patients achieved excellent results, 23% good (CI = 70-75), and 6% poor. Reintervention was unnecessary. CONCLUSIONS: EACS without PHT demonstrates favorable anthropometric results, cost reduction, and simplified postoperative management.

Is Postoperative Helmet Molding Therapy Necessary for Craniectomy for Sagittal Suture Synostosis?

Endoscopic strip craniectomy followed by postoperative remodeling helmet therapy for scaphocephaly is widely accepted, but the requirement of several helmets might burden patients or their families. This study examined whether craniectomy via a bicoronal approach without molding helmet therapy is worth considering. The authors retrospectively reviewed patients with nonsyndromic sagittal suture synostosis who underwent the modified Renier H technique between 2016 and 2021. We collected data on preoperative and postoperative cephalic index (CI), operative time, estimated blood loss, and blood transfusion rates. The authors also examined all related literature in English describing endoscopic craniectomy with postoperative helmet molding therapy for sagittal suture craniosynostosis. Among 17 patients, the average operative time was 92.2±15.6 minutes, the mean estimated blood loss was 35.8±22.4 mL, and a blood transfusion was needed for 9 patients (52.9%). The mean preoperative and postoperative CIs were 69.1±2.6 and 78.4±2.2, respectively. A comparison of the literature review with the authors' results showed that their procedures required a slightly longer operative time and a higher frequency of blood transfusions. There are no significant differences in blood loss or preoperative and postoperative CIs reported in the literature. The open procedure required a higher operative time than endoscopic suturectomy. However, dealing with bleeding is more challenging with endoscopic suturectomy. The cost of the helmets and the duration patients have to wear them, which might be burdensome for the patients or their families when determining the optimal minimally invasive treatment, should also be considered.

The effect of a helmet type, home-use low-level light therapy device for chemotherapy-induced alopecia: study protocol for a randomized controlled trial.

BACKGROUND: Alopecia is one of the most common adverse effects of chemotherapy. It reduces the patient's self-esteem and quality of life and the effect of therapy. Scalp cooling is the only verified current method for prevention but success is not guaranteed, particularly after receiving anthracycline-based combinations. Low-level light therapy has been clinically proven to inhibit the progress of androgenic alopecia. A previous study using human subjects shows limited benefits for low-level light therapy for patients who suffer chemotherapy-induced alopecia but an increase in the number of probes and the optimization of light sources may improve the efficacy. This study determines the efficacy of low-level light therapy for the prevention of chemotherapy-induced hair loss for patients with breast cancer using a randomized controlled trial. METHODS: One hundred six eligible breast cancer patients were randomly distributed into a low-level light therapy group and a control group, after receiving chemotherapy. Subjects in the low-level light therapy group received 12 courses of intervention within 4 weeks. Subjects in the control group received no intervention but were closely monitored. The primary outcome is measured as the difference in the hair count in a target area between the baseline and at the end of week 4, as measured using a phototrichogram (Sentra scalp analyzer). The secondary outcomes include the change in hair count at the end of week 1, week 2, and week 3 and hair width at the end of week 1, week 2, week 3, and week 4, as measured using a phototrichogram, and the change in distress, the quality of life, and self-esteem due to chemotherapy-induced alopecia, at the end of week 4, as measured using a questionnaire. DISCUSSION: This study improves cancer patients' quality of life and provides clinical evidence. TRIAL REGISTRATION: Registered at ClinicalTrials.gov- NCT05397457 on 1 June 2022.

El pediatra y los padres en la toma de decisiones de tratamiento en plagiocefalia posicional: una revisión narrativa / The pediatrician and parents in treatment decision-making in positional plagiocephaly: A narrative review

La plagiocefalia posicional (PP) es una de las causas más frecuentes de consulta en neurocirugía pediátrica. La incidencia de PP aumentó en los '90, a partir de la campaña Dormir de espaldas. Junto con el aumento de la demanda de atención, se verifica un debate acerca de la eficacia de los distintos tratamientos. La interacción padres ­ pediatra orientada a elegir la mejor terapéutica adquiere importancia, particularmente cuando se trata de decisiones sensibles a la preferencia. Es necesario saber más acerca de la naturaleza de la toma de decisiones de tratamiento de PP, para contribuir al desarrollo de procesos decisorios eficaces. Se realizó una revisión narrativa sobre investigaciones en toma de decisiones de tratamiento en PP. Se identificaron artículos en PubMed y Google Scholar (1990 ­ 2022) en una búsqueda con los descriptores "plagiocephaly", "decision making" y "parents". Se incluyeron artículos cuyo tema central fuera la toma de decisiones en PP, o que la desarrollaran como parte de otro tema. Se excluyeron trabajos en los que la toma de decisiones aparece de modo secundario o tangencial. Se encontraron 3 artículos con distintos diseños metodológicos, en los que la severidad de la presentación, los elementos socioculturales y emocionales, y los aspectos relacionados con el tratamiento son los factores más implicados en la toma de decisiones. Las relaciones entre la ansiedad parental, las expectativas de tratamiento y la percepción subjetiva de la PP, y el rol del pediatra como proveedor de información válida y confiable son temas que necesitan de ulterior investigación (AU)

Positional plagiocephaly (PP) is one of the main reasons for consultation in pediatric neurosurgery. The incidence of PP increased in the 1990s, after the "Back to Sleep" campaign. Concurrently, the growing demand for care has led to a debate regarding the effectiveness of the different treatments. The parent-pediatrician interaction is aimed at choosing the best therapeutic approach becomes important, particularly when it comes to preference-sensitive decisions. There is a need to better understand the nature of PP treatment decision-making in order to contribute to the development of effective decisionmaking processes. In this narrative review, we evaluated the research on treatment decision-making in PP. Articles were identified in PubMed and Google Scholar (1990 - 2022) using the search terms "plagiocephaly", "decision-making" and "parents". Articles were included if their central theme was decision-making in PP, or if they developed it as part of another subject. We excluded articles in which decision-making appeared in a secondary or tangential way. Three articles were identified with different methodological designs, in which the severity of the presentation, sociocultural and emotional aspects, and aspects related to treatment were the factors most implicated in decision making. The relationships between parental anxiety, treatment expectations, subjective perception of PP, and the role of the pediatrician as a provider of valuable and reliable information are topics that require further investigation (AU)

Using e-scooters: An easy way to get home or a nightmare? An orthopedic perspective on e-scooter accidents.

BACKGROUND: The percentage of e-scooter use quickly escalated in our community due to its convenience, low cost, and eases of use. The number of accidents causing high-energy traumas has also increased. This study aims to describe the demographic char-acteristics and fracture patterns of patients admitted to the emergency department following an e-scooter accident and to identify common, correctable factors that increased the likelihood of accidents. METHODS: Between January 2022 and August 2022, 43 patients (20 females and 23 males) who were admitted to the emergency department after an e-scooter accident and developed extremity fractures were included. The patients were divided into 2 groups those treated surgically and conservatively. Parameters such as the time of the accident, education level of the user, alcohol use, e-scooter malfunction, and compliance with traffic rules were evaluated. RESULTS: Accidents that led to treatment by surgery mostly occurred between 11 pm and 7 am. Surgically treated patients were mostly high school graduates. Alcohol use and recreational scooter use rates were statistically higher in the operated patients when compared to patients who were treated conservatively. The number of patients who reported a malfunction in the e-scooter was significantly lower in the operated group than in the conservative group. The rates of accidents due to non-compliance with traffic laws, driving at full speed of the e-scooter, use on the driveway, and presence of wet ground at the time of the accident were higher in the surgically treated patient group. Surgically treated patients also had a higher rate of being 1st time e-scooter users. CONCLUSION: Although governments have introduced many regulations regarding e-scooter use, the current situation seems insufficient in solving the problem. E-scooter users should be further educated about the associated risks. Authorities should tighten their supervision of scooter rental companies and drivers. Nighttime usage conditions should be reviewed, and the use of alcohol should be controlled. The use of helmets should be mandatory. If such regulations are tightened, accident rates can be reduced or high-energy impacts from existing accidents can be avoided. The results suggest that experienced, slow, non-alcoholic, and rule-abiding drivers require less operative treatment. This article will hopefully raise awareness and improve e-scooter regulations.

Inverse identification of region-specific hyperelastic material parameters for human brain tissue.

The identification of material parameters accurately describing the region-dependent mechanical behavior of human brain tissue is crucial for computational models used to assist, e.g., the development of safety equipment like helmets or the planning and execution of brain surgery. While the division of the human brain into different anatomical regions is well established, knowledge about regions with distinct mechanical properties remains limited. Here, we establish an inverse parameter identification scheme using a hyperelastic Ogden model and experimental data from multi-modal testing of tissue from 19 anatomical human brain regions to identify mechanically distinct regions and provide the corresponding material parameters. We assign the 19 anatomical regions to nine governing regions based on similar parameters and microstructures. Statistical analyses confirm differences between the regions and indicate that at least the corpus callosum and the corona radiata should be assigned different material parameters in computational models of the human brain. We provide a total of four parameter sets based on the two initial Poisson's ratios of 0.45 and 0.49 as well as the pre- and unconditioned experimental responses, respectively. Our results highlight the close interrelation between the Poisson's ratio and the remaining model parameters. The identified parameters will contribute to more precise computational models enabling spatially resolved predictions of the stress and strain states in human brains under complex mechanical loading conditions.

E-scooter-related orthopedic injuries and the treatments applied: are these scooters a new means of transportation or a new source of trauma?

INTRODUCTION: E-scooters have become increasingly popular in Turkey due to easy accessibility. In parallel with this, the number of e-scooter-related injuries has increased gradually. The aim of this study was to determine the types of e-scooter-related orthopedic injuries, to evaluate hospitalization and surgical treatments, and to investigate the loss of work of patients and the burden incurred by the healthcare system. MATERIALS AND METHODS: This retrospective multicentre study included all orthopaedic referrals, who were admitted to two major trauma departments in Diyarbakir from January 2022 to July 2022. Patient data were analyzed, including demographic characteristics, injury pattern, types of injury and subsequent treatment. RESULTS: In a total of 62 patients, 105 orthopaedic injuries were identified, comprising 72.5% males and 27.5% females, with a median age of 34.21 years. Fifty-six (90.3%) patients were riders, and six were pedestrians. All associated e-scooters were rented. There were 44 fractures (41.9% of the total recorded injuries) including 8 (12.9%) open fractures. Surgery was required by 32 patients (51.6%) and 35 (56.4%) required hospital admission leading to hospitalization of 3.7 days on average. The average job loss of working patients after injury was determined as 2.4 months. Helmet use was detected in 6.4% of the e-scooter users, but no other protective equipment was detected in any of the patients. Furthermore, 19,3% of the patients had a blood alcohol level of > 10 mg/dl. CONCLUSIONS: The injuries that may result from an e-scooter accident can have long-term hospitalization and long-term job loss in the community. This imposes a significant financial burden on the national healthcare system and adversely affects public health. There is a need for precautions to be implemented such as infrastructure organisation, increased awareness of motor vehicle riders and e-scooter riders, and increased enforcement of rule compliance including not using e scooters after alcohol consumption and the use of protective equipment.

Electric Scooter-related Craniofacial Injuries.

OBJECTIVES: Injuries associated with the use of electric scooters are a serious problem in modern society and traffic in relation to their increasing frequency of use. Although injuries involving all body parts are seen in such injuries, craniofacial ones are also very common. The aim of this study was to evaluate the craniofacial and other accompanying injuries in electric scooter-related accidents in Istanbul. MATERIALS AND METHODS: Between January 2020 and December 2022, patients with electric scooter-related trauma among the patients admitted to the emergency unit for trauma were evaluated retrospectively. All electronic medical records, CT scans, other examinations, and treatments were retrospectively reviewed, and craniofacial fractures and other injuries seen in the patients were classified. RESULTS: A total of 20.358 patients were admitted to the trauma unit between January 2020 and December 2022. Two hundred ten patients (142 male, 68 female) had electric scooter-related trauma and 58.1 % of them had craniofacial injuries. Thirty patients (14.3 %) (23 male, 7 female) had craniofacial fractures, whereas 43.8 % of them had craniofacial soft tissue injuries. The nasal fracture was the most common craniofacial fracture (14 patients, 46.7%). Orbital wall and zygomaticomaxillary complex fractures were found to be the second most common fractures. CONCLUSIONS: The rate of electric scooter-related injuries among all trauma patients admitted to the emergency trauma unit during the mentioned period was 1.03%. The results of this study were found to be in accordance with the data in the literature. The craniofacial region is the most frequently injured body part in patients with electric scooter-related trauma, and patients should be comprehensively evaluated for possible soft tissue injuries, craniofacial fractures, and other accompanying system injuries.

Western Australian State Trauma Registry analysis of incidence and injury patterns associated with e-Scooter injuries: 5-year retrospective case series.

BACKGROUND: Electric scooters (e-Scooters) are a form of motorized vehicle that offers cheap, efficient and environmentally friendly transportation. Increased e-Scooter utilization has been accompanied by increases in e-Scooter related injuries in multiple countries. This project describes the incidence, injury pattern, injury severity and patient factors associated with e-Scooter use from the Western Australian State Trauma Registry. METHODS: Retrospective cohort of all trauma patients captured by the Western Australian State Trauma Registry between 01 July 2017 and 30 June 2022 were analysed. Patient demographics, helmet use, reported drug use, and injury details (including principal and additional diagnoses, ISS) were collected. RESULTS: Eighty-one patients sustained e-Scooter related injuries between 2017 and 2022. Fifty-four (66%) of hospital admissions were recorded in 2021-2022, an annual percent change of 385.7% from the previous year. Most patients were male (80%). Median age was 40 years (IQR: 32-50). Helmet use was reported in 43% of patients. Helmet use was associated with a significantly lower odds of head injury (OR = 4.42, CI: 1.38-14.21; P = 0.01). Thirty-five percent of patients were intoxicated with either alcohol or drugs. Forty-four (54%) patients required surgery. CONCLUSION: E-Scooter crashes are a new mechanism of injury affecting patients captured by the Western Australian State Trauma Registry. Helmet use correlated with a reduced risk of head injury.

Electric scooter-associated orthopedic injuries cause long absence from work, regret and are emerging as a major cause of hip fractures in young individuals: a comprehensive study from a regional trauma center in a densely populated urban setting.

PURPOSE: This study aimed to give a full spectrum of orthopedic injuries associated with electric scooter (e-scooter) use and analyze related factors, report on follow-up data from the patient's perspective and make a comparative etiological analysis of young adult hip fractures. METHODS: A total of 851 consecutive patients were admitted to the Emergency Department following e-scooter injuries between January 2021 and July 2022, of whom 188 had 214 orthopedic injuries. The demographics, injury, and incident characteristics of these patients were collected. All fractures were classified as per the AO/OTA classification. Two groups were created as operatively or conservatively treated patients and data were comparatively analyzed. Follow-up examination incorporated a survey using binary questions on patients' perspectives. An etiological comparative analysis of hip fractures in young adults admitted to the same center between 2016 and 2022 was conducted. RESULTS: The median patient age was 25. Inexperienced drivers constituted 32% of the injured. The protective gear use rate was at 3%. Higher speed (p = 0.014) and age (p = 0.011) were significantly associated with operative treatment. A total of 39% of the operated patients could not return to preinjury physical function, while 74% regretted using an e-scooter. The most common etiological factor for traumatic young hip fractures was fall from a height between 2016 and 2020, whereas it became e-scooter accidents in 2021-2022. CONCLUSION: The rate of e-scooter-related operative treatment is high and leaves the patient in regret (84%) and a physically limited condition (39%). A speed limit of ≤ 15 km/h could decrease the rate of operative injuries. The e-scooter was identified as the top etiological factor in the last 2 years for traumatic young hip fractures. LEVEL OF EVIDENCE: II, Diagnostic cohort study.

Injury patterns and outcomes in motorcycle passengers.

INTRODUCTION: Contemporary trauma literature on injuries to motorcycle passengers is scarce. The aim of this study was to examine the injury patterns and outcomes of motorcycle passengers with regard to helmet use. We hypothesized that helmet utilization affects both injury type and outcomes. METHODS: The National Trauma Data Bank was queried for all motorcycle passengers who were injured in traffic accidents. Participants were stratified according to helmet utilization into helmeted (HM) and nonhelmeted (NHM) groups. Univariate and multivariate analyses were performed to compare the injury patterns and outcomes between the groups. RESULTS: A total of 22,855 patients were included for analysis, of which 57.1% (13,049) used helmet. The median age was 41 years (IQR 26-51), 81% were female, and 16% of patients required urgent operation. NHM had higher risk of major trauma (ISS > 15: 26.8% vs 31.6%, p < 0.001). The most frequently injured body region in NHM was the head (34.6% vs 56.9%, p < 0.001), whereas in HM patients was the lower extremities (65.3% vs 56.7%, p < 0.001). NHM patients were more likely to require admission to the ICU, mechanical ventilation, and had significantly higher mortality rate (3.0% vs 6.3%, p < 0.001). The strongest predictors of mortality were GCS < 9 on admission, hypotension on admission, and severe head injury. Helmet utilization was associated with decreased odds of death (OR 0.636; 95% CI 0.531-0.762; p < 0.001). CONCLUSION: Motorcycle collisions can lead to significant injury burden and high mortality in motorcycle passengers. Middle-age females are disproportionally affected. Traumatic brain injury is the leading cause of death. Helmet use is associated with decreased risk of head injury and death.

Craniofacial Trauma from Electronic Scooter Use.

BACKGROUND: In 2018, the City of Providence introduced a program in which electronic scooters were deployed for public use. We aim to characterize the burden of craniofacial injuries associated with these scooters. METHODS: A retrospective review was conducted of all patients consulted to the plastic surgery service for evaluation of craniofacial injury between September 2018 and October 2022. Data pertaining to patient sociodemographics, site and time of injury, and craniofacial trauma were recorded. RESULTS: Twenty-five patients sustaining craniofacial trauma were identified over a four-year period. Most patients required soft tissue repair (64%) and bony fractures were sustained by approximately half of all patients (52%). Admission to ICU was uncommon (16%), and there were no fatalities. CONCLUSIONS: The incidence of craniofacial injury from electronic scooter use is low. However, these injuries may involve extensive surgical reconstruction and ICU admission. We advise the City of Providence to optimize best safety practices and monitoring to minimize risk.

Comparison of molding helmet therapy versus natural course in twins with nonsynostotic head deformation.

This observational study aims to compare the effectiveness of helmet therapy versus natural course in twin siblings suffering from nonsynostotic head deformations. A retrospective analysis of all twin couples treated with helmet therapy between March 2009 and May 2017 at an orthopedic hospital was conducted. Inclusion criteria were me if only one twin received helmet therapy. The other twin acted as control. A classification for different head shapes was used. A total of 61 twin couples was included. Change in outcome parameters of helmet therapy and natural course differed significantly: cranial vault asymmetry (CVA) -0.66 cm vs. -0.04 cm, cranial vault asymmetry index (CVAI) -5.35% vs. -0.51% (both p < 0.001), cephalic index (CI) -3.10% vs. -1.91% (p = 0.006). Helmet therapy showed a success rate (CI < 90% and CVAI ≤7% or better) of 63.6% vs. 21.1% in children with natural course (p = 0.002). Within the limitations of the study it seems that the results of this retrospective, single-center study confirm that helmet therapy to be a reliable treatment for mild to severe positional head deformation.
