Plate fixation using parallelogram prism iliac bone grafts for clavicle oblique nonunion with shortening deformity: a case report

BackgroundPlate fixation using a tricortical iliac bone graft can provide a high ratio of bone union and restore clavicle length in cases of atrophic nonunion. However, the surgical treatment of clavicle oblique nonunions with marked shortening deformity remains challenging and unresolved. Here, we describe a case of clavicle oblique nonunion with shortening that was treated using plate fixation with parallelogram prism iliac bone grafts.Case presentationA 46-year-old man presented to our hospital with severe medial scapular pain. He had been diagnosed with a right clavicle mid-shaft fracture in a motorcycle accident 9 months earlier. He underwent conservative treatment, but radiographs and computed tomography showed clavicle oblique nonunion with marked shortening. Physical examination revealed no pain at the nonunion site; however, tenderness was noted on the medial side of the right scapula and protrusion of the inferior scapular angle was prominent. His symptoms interfered with daily life and required surgery. After release of the nonunion, we harvested the parallelogram prism bone grafts from the iliac crest. We inserted these bone grafts into the fracture ends and fixed them with lag screws, after which we performed plate fixation. Immediately after surgery, right medial scapular pain and scapula winging subsided. Bone union was achieved, and the length of the clavicle was restored at 9 months postoperatively.ConclusionsThis case report provides new information on the surgical treatment of clavicle oblique nonunion with shortening deformity. The presence of medial scapular pain and winging scapula can be clinically problematic in cases of clavicle nonunion with marked shortening. Our case revealed that reliable bone union and clavicle length recovery can be achieved with plate fixation and iliac bone grafts.

Investigation into the effects of emergency spray on thermal runaway propagation within lithium-ion batteries

Inhibition a battery's thermal runaway propagation can avoid serious accidents in electric vehicles. Emergency spray has been proven to be effective in suppressing thermal runaway of a single cell, but the effect of inhibiting thermal runaway propagation between multiple batteries still needs further investigation. In this study, the characteristics of thermal runaway propagation was experimentally investigated, and the emergency spray technology, with different cooling durations, was applied in various stages of thermal runaway propagation. The results indicated that the continuous spray could not only reduce the average maximum temperature, but also delay the diffusion among multiple batteries and provide further response time. However, after-combustion was a frequent occurrence when the spray shut down. A correlation model was proposed to evaluate the maximum heat production of lithium-ion batteries by calculating the enthalpy and mass of the reactants and short circuit energy. The required cooling quantity is determined by experiment and verified by experiment. These results could help the development of a cooling strategy for suppressing the thermal runaway propagation effectively with minimum cooling capacity.

Traffic Sign Detection using Convolutional Neural Networks

Abstract: Signs on the road are crucial making sure the flow of traffic is smooth. Disregard whilst watching the traffic sign board is one of the main causes of traffic accidents. Traffic signs are essential for controlling traffic, preventing accidents, and assuring safety.No entry, speed limit, traffic lights, left or right turn, children crossing, etc. are just a few examples of various sorts of signs. The human observation of traffic control signals under the current approaches could lead to a re-entry collision of cars. The fast-moving traffic may be delayed as a result. Additionally, they impede traffic by stopping cars at the intersection during rush hour. The revised approach uses Deep Learning to reduce the amount of time and effort required to monitor these

Diastasis of Symphysis Pubis In 18-Years Old Female Patient Treated With Conservative Pelvic Binder: Case Report

Background: Pelvic trauma is commonly associated with high-velocity force-like road traffic accidents and carries high rates of complications, including diastasis of the symphysis pubis. The diastasis of symphysis pubis prevalence rate has been reported at 13-16%. This case report aimed to review the effectiveness of conservative pelvic binders in diastasis of the symphysis pubis in the emergency setting.Case Report: An eighteen years old female patient was referred to the Emergency Unit because of a motorcycle accident. She revealed worsening abdominal pain, unable to move both legs and swollen and bruised vulva. The patient is fully conscious, and the vital sign revealed low blood pressure of 89/56 mmHg. The AP pelvis X-ray showed diastasis symphysis pubis marked 3.87 cm wide. Immediate resuscitation was performed, stabilizing the pelvis using a conservative pelvic binder. X-ray evaluation showed surprisingly successful results as the symphyseal gap reduced to 0.66 cm. Discussion: In this case, the symphyseal gap was >2.5 cm, indicating surgical treatment. Recent studies suggest conservative therapy has good outcomes in the symphyseal gap >2.5 cm. Considering the patient's young age and no comorbidities, it was assumed that the healing process would occur quickly, so conservative treatment was chosen first. However, further evaluation is still needed due to the limitation of the follow-up from the patient. Conclusion: Conservative treatment using a pelvic binder called gurita is effective for emergencies with inadequate medical equipment.

Improving Safety of Passenger Road Transportation

The objective is to increase the passenger road transportation safety by developing an improved model of the transport process with minimal risks of incidents. The Functional Resonance Analysis Method (FRAM) was used to determine the factors influencing the reliability of transportation, which is based on the study of the functions of the process of passenger road transportation based on six different aspects: time, control, output, resource, prerequisites, and input. It was clarified that the main reason for violation of traffic rules by drivers of passenger buses is the psycho-physiological state of the driver, which depends on the experience, duration of the work shift, duration of operation of the passenger bus, speed of movement, stress load. The most important criteria among those mentioned are professional work experience and speed of movement of a passenger bus. It is the combination of these criteria with the time of execution of a production task without the introduction of appropriate control over it that leads to a high probability of an incident. In addition, the human factor, directly the specialists' professional experience (the transportation organization manager, the mechanic checking a passenger bus before starting work, doctor, driver), also significantly affects the safety of the transportation process. The analysis of the causes of road traffic incidents confirmed the close connection between the probability of an undesirable event and human error, and the strengthening of control over the psycho-physiological state of the driver increases the reliability of passenger road transportation and reduces the probability of failures in the performance of transport work. The originality of the research lies in the established relationship between functions and criteria that have an impact on the safety of the transport process, which makes it possible to assess the level of reliability of the performance of the assigned task within the specified time; the practical significance lies in the quantitative assessment of these criteria and the provision of recommendations for monitoring the psycho-physiological state of the driver at all stages of the process of passenger road transportation.

Bone Defect of the Tibia: A Case Report

Abstract: Defects in long bones including tibia are still difficult problems in orthopaedic field for both the physician and the patient. We reported a case of a 56-year-old woman who came to the hospital with the chief complaint of being unable to walk since she was nine years old after getting a motorcycle accident. The patient complained that her leg did not grow since then. The patient was fully conscious and hemodynamically stable. Physical examination revealed that there was a deformity of the left lower leg with shortening of the lower leg and absence of the tibial bone. The patient was diagnosed with left tibia bone defect, therefore, above-the-knee amputation was performed. The amputation must be viewed as an opportunity to re-establish or enhance the patient’s functional level and facilitate a return to near normal locomotion using a prosthesis after amputation. Soft tissue and muscle quality, bone condition, neurovascular conditions and function of the limb can be considered in the selection of therapy in bone defect. The level of amputation can be determined by assessing the bone condition, neurovascular condition, and the ability of muscle and skin flaps to close the wound. In conclusion, amputation can be the treatment of choice for patient with bone defect. Improving lower limb function is proven to maximize the patient quality of life. Keywords: bone defect tibia; above-the-knee amputation; transfemoral amputation

Teaching Neuro Images : Reversible pontomesencephalic edema caused by traumatic carotid cavernous fistula

A 45-year-old man presented with a painful bulging right eye and blindness 6 weeks after a motorcycle accident and traumatic brain injury. He had a complete right oculomotor nerve palsy and only perception of light. MRI revealed ipsilateral pontomesencephalic edema (figure, A and B). Catheter angiography showed a direct right carotid-cavernous fistula (figure, C). Two months after coil embolization, the ptosis, proptosis and ophthalmoplegia resolved. MRI revealed resolution of pontomesencephalic edema (figure, D). The presumed mechanism was transmission of arterialized pressures of the cavernous sinus via a bridging vein to the anterior pontomesencephalic vein, generating venous hypertension and vasogenic edema.1,2

Effects of local infiltration of peripheral blood mononuclear cells with phonophoresis on wound healing in dogs

A total of six dogs with extensive wounds of 5×5 cm2 size and above were taken with the objective of evaluating the efficacy of autologous peripheral blood mononuclear cells (PBMC) with phonophoresis on wound healing in dogs. Autologous PBMCs were isolated freshly on 0, 7, 14, 21 and 28th day from blood by using density gradient centrifugation. Obtained PBMC was infiltrated around the wounds. Phonophoresis was done using therapeutic ultrasound massage at 0.5 watts/cm2 for 10 min for all the six animals. Clinical evaluation and wound planimetry was performed during post treatment period. Most affected breed was mongrel and main aetiology was automobile accident. The wounds were mostly located on limbs, neck and abdominal region. PBMC was noticed to be compatible to the tissues. No signs of infection were noticed in the wounds after administration of PBMC, rather healthy granulation tissue-formation, increasing values of wound contraction, epithelization and healing were noticed. PBMC-phonophoresis in wound healing of canines in present study was found to be effective in extensive wounds.

To describe clinical situations for use of modified VAC in POC based on: diagnosis, comorbidities, BMI, wound size in cm, days following trauma when VAC was first applied, total duration of uninterrupted use, frequency of change, settings, bacterial growth, outcomesTo report the outcomes of mVAC use in POC within 6 months to help improve and standardize its application in the institutionThis study involves data gathering from inpatients handled by orthopedic surgeons in training and subspecialty rotations in POC. The data collected are highly dependent on the doctors-in-charge's complete charting, thorough reporting and accurate documentation. Modified Vacuum Assisted Closure (mVAC) is used frequently in this study and is defined as a form of revised, adapted and reformed use of VAC based on available materials in the involved institution. The materials that are included are, but not limited to the following: sterile Uratex™ blue foam, nasogastric or suction tubing, phlegm suction machine, Bactigras™ and Opsite™ or Ioban™.A total of 58 patients were included in the study. The average age of the population was 35 and are predominantly male. The most common mechanism of injury was motorcycle accident and 37 of the patients were diagnosed with an open fracture of the lower extremity with open tibia fractures (22) being the most common. Average wound area measured was 24.12 cm3. All patients yield a bacteria growth with e. coli being the most frequent. Average during of uninterrupted use was 39 days. Of the 58 included in the study, 8 patients underwent STSG, 2 had a flap coverage surgery, 4 patients eventually underwent amputation and 33 with complete resolution of soft tissue defect after conversion to biologic dressing post-mVAC. The rest of the population were still ongoing mVAC at the end of the study.mVAC is an alternative temporary medium for soft tissue coverage for cases with or without concomitant fractures. mVAC promotes removal of exudate from the wound, supports wound apposition and granulation bed proliferation. Usage mVAC helps prepare for skin coverage procedure and on some cases leads to full resolution of defect.

Developing an Alternate Mineral Transportation System by Evaluating Risk of Truck Accidents in the Mining Industry—A Critical Fuzzy DEMATEL Approach

The innovative transportation system is a pertinent need for the mining industry. Truck haulage is currently the most common mode of mineral transportation between the excavation sites and end use plants. However, besides being resource-intensive and inefficient, this mode of transportation accounts for a high number of accidents and injuries. In order to reduce the occurrence of accidents, it is important to first understand the primary contributors to truck-related occupational risks and then develop strategies to eliminate such risks. The available literature predominantly advocates for the use of statistical or probabilistic methodologies that suffer from considerable limitations. This paper utilizes the Fuzzy DEMATEL (Fuzzy Decision-Making Trial Evaluation Laboratory) approach to conduct an in-depth assessment of the critical factors that result in mining accidents involving trucks and the relationships between these factors, presented using a cause-and-effect diagram. The study also includes a sensitivity analysis for validating the robustness of the fuzzy model. The results show that high speed and aggressive driving is the most important causal factor behind accidents. The negative impact on socio-economic conditions of local community members is also discussed. Among other preventive measures, the paper emphasizes the pipe conveyor system as an alternate and safer mineral transportation system.

Stable condition: Traumatic injury, coma, and vital traffic in a Mumbai hospital ward

AbstractBased on five years of research in a public‐hospital trauma ward in Mumbai, this article examines the fraught case study of comatose states that result from traffic‐accident injuries. It focuses on a relationship between two brothers, one injured in a motorcycle accident and in a coma, and the other caring for him. The article asks: How do people navigate life‐and‐death situations through both stillness and motion? Addressing this question requires recasting traumatic injury from a wound that lodges in a single body to an intersubjective problem of discontinuous and relational traffic. In moments of transfer to the hospital, prognosis about vital signs, and reflections on death, the embodiment of and care for traumatic injury materializes through uneven relationships of intermittent motion. The article develops the analytic ofvital trafficto describe these relationships and analyzes the temporal and spatial discontinuities that shape and undermine stability after injury occurs. Differences in vital traffic matter to patients, families, providers, and to the very possibility of survival. The implication of this finding is a better understanding of the sociality of injury and its care. Beyond the case of medicine, attention to vital traffic can illuminate the flux of ethnography itself.

Causal analysis of coach and bus accidents in China based on road alignments

Given the complexity and the difficulty of controlling contributors effectively, road passenger transport often results in serious injuries and fatalities. The purpose of this study is to identify the main contributors to coach and bus accidents and to provide policy recommendations for making improvements in accident prevention. The Driving Reliability and Error Analysis Method 3.0 (DREAM 3.0) was modified and used to analyze the contributing factors (i.e. phenotypes and genotypes in DREAM) and their casual mechanisms. By having statistical analysis and social network analysis (SNA) adopted, the main genotypes and phenotypes of the DREAM charts were identified. The results of the study showed that A2.1 (too high speed) was the key phenotype and the main genotypic process chain leading to the phenotype was “inadequate safety management → inadequate training → inadequate skills/knowledge → misjudgment of the situation → too high speed” on all types of road. For A2.1 (too high speed), C2 (misjudgment of the situation) was the dominant genotype, while N5 (inadequate safety management) was the root cause of most genotypes. This suggests that road passenger transport companies, as the responsible parties, often fail to implement or violate safety prevention and control systems. Government regulators should promote the policy system and incentivize them to fulfil their safety management responsibilities. The government should also educate the public and improve the road environment to reduce passenger-related risks and the impact of environmental factors on drivers.

Maluf, a urology resident wrote perhaps the most fascinating account in 1954 that typically ignored the herculean contributions of one Charles R. Drew, M.D. METHODS: William Harvey first elucidated the circulation of blood in 1628 but there was obviously some appreciation on the criticality of blood loss after injury. Richard Lower tried to keep dogs alive with transfusion by 1665. However, blood groups and their importance had to await Karl Landsteiner’s discovery in 1900. We reviewed the history of blood transfusions during WWI, WWII, and the Korean War along with the work of Charles R. Drew, M.D. RESULTS: “So much of our energy is spent in overcoming the constricting environment in which we live that little energy is left for creating new ideas or things. Whenever, however, one bread out of this rather high-walled prison of the ‘Negro problem’ by virtue of some worthwhile contribution, not only is he himself allowed more freedom, but part of the wall crumbles.” Drew was born in Washington, D.C. on June 3, 1904. He attended Amherst College and was a brilliant athlete as well as student. He attended and graduated from McGill University’s school of medicine in 1933 and AOA. He went to Howard University on graduation and his doctoral thesis earned his advanced degree from Columbia University on “Banked Blood.” He received a two-year Rockefeller fellowship and began working on improved methods of collection, preservation, and marketing blood donation. He also developed the Blood for Britain Campaign at the outset of WWII. CONCLUSIONS: “The life of the body is the blood.” Genesis 9:4. In 1941 it was Dr. Drew who was appointed the first American Red Cross Blood Bank director in charge of the blood supply for U.S. Army and Navy. In 1942 when the military refused to pool blood and insisted on segregation of African-American from white blood he resigned his official posts. Drew died of a tragic automobile accident on April 1, 1950 in Burlington, N.C. leaving his wife, Lenore and four children as his legacy.

Design and Application of Deep Learning-Based Crash Damage Prediction Model for Self-Driving Cars

Abstract The collision damage of automated cars has grown in importance as self-driving car technology has advanced to the pilot operation stage. To enhance the safety of autonomous vehicles by predicting and preventing potential hazards during autonomous driving, this study presents a model for collision damage prediction in automated driving cars. The model optimizes deep convolutional neural networks using the self-attention mechanism and incorporates a degree convolutional neural network algorithm with the attention mechanism. Its application is key to reduce risks in autonomous driving. The results demonstrated that the accuracy, reliability, specificity, and Mathews correlation coefficient of the improved algorithm were 94.0%, 94.8%, 93.6%, and 0.88, respectively, resulting in a high overall performance. The prediction model's accuracy during training on the training data set and validation data set was 100% and 98%, respectively, demonstrating its efficacy. The prediction model's prediction accuracy in calculating the degree of auto collision damage for 10 working conditions in the validation data set was 83.3%. The prediction results were essentially consistent with the trend of the actual collision damage degree curve, demonstrating both the viability and high prediction accuracy of the prediction model. The aforementioned findings demonstrated the model's strong performance and great application value in the field of self-driving car collision avoidance and warning.

Identification of factors increasing the risk of pedestrian death in road accidents involving a pedestrian with a motor vehicle

Walking is a basic form of activity for every human being and has many advantages, including health, economic and environmental benefits. Every journey made using various means of transport begins and ends on foot. As is well known, the group of road users particularly exposed to the risk of serious injury in road accidents, apart from cyclists, also includes pedestrians. These are the so-called vulnerable road users. Pedestrians are a group of road users that is often deprecated by many drivers of motor vehicles, but very important in road traffic. Pedestrian injuries and pedestrian fatalities have enormous social and economic consequences. The problem of high pedes-trian risk on Polish roads is well known and has been widely described in the scientific literature last few years. However, the reasons for this state of affairs have not been fully explained, as evidenced by the statistics of road traffic incidents. Despite many studies in this area, the causes indicated in the research often differ depending on the area of analysis, the environment in which the incident took place, location, participants of the incident, environmental conditions, behaviorism and many other features. Therefore, the main goal of the article was to determine the factors influencing the formation of fatalities in road traffic accidents among pedestrians in acci-dents involving pedestrians and motor vehicles in the Silesian Voivodeship (Poland) in 2016-2021. The logit model presented in the article allowed for the conclusion that the main attributes influencing the increasing the risk of pedestrian death in road accidents involving a pedestrian with a motor vehicle include such features as driving under the influence of alcohol by the driver, exceeding the speed limit by the vehicle driver, when the road incident involves a heavy vehicle (truck, bus), a pedestrian is a male, pedestrian is over 60 years old, is under the influence of alcohol, the incident took place outside built-up area, at night, i.e. from 10:00 p.m. up to 6:00 a.m, in other than good weather conditions. The obtained results can be used in various activities, campaigns aimed at improving the safety of pedestrian traffic in the area of the analysis.

Analysing Young Motorcyclist Trip and Parking Behaviours: A Strategy to Reduce Motorcycle Accident Numbers

Motorcycle numbers in Indonesia are growing rapidly and contribute 84.4% of total motor vehicles. The death numbers from road traffic accidents (RTA) involving motorcycles also increase to 74% of the deaths, including young motorcyclists. WHO reported that RTA is the leading cause of death for people aged between 5-29 years. A series of Revealed and Stated Preference surveys have been undertaken to explore the characteristics of young motorcyclist trips and their behaviors towards three different virtual parking schemes aimed at finding the best parking schemes to control motorcycle usage among young motorcyclists. Therefore, the number of young motorcyclist-related RTA could be reduced. The finding suggests that young motorcyclists preferred using off-street parking over on-street parking. The preferred distance between parking premises and activity centers is less than 50 meters. The off-street parking would be selected instead of the on-street parking, although its price is higher. The Willingness to pay for each proposed parking scheme is IDR 3,373, IDR 3,509, and IDR 3,618. It is below the ability to pay, which is IDR 4,100. Thus, an on-street parking scheme with progressive pricing and a minimum base price of IDR 5,000 is proposed, where at least 30% of parking lots should be allocated for short-term parking. Finally, the proposed parking scheme must be supported by reliable public transport services based on the young motorcyclist preferences, which would be the direction of future research.

Designing of Intelligent Video-Surveillance Systems in Road Tunnels Using Software Tools

Video Surveillance Systems (VSSs) are integral parts of road tunnels. Currently, they perform a number of functions, such as ensuring the protection of tunnel technologies, monitoring tunnel operation, or recognising license plates. If VSSs are to be designed to protect the tunnel and its technologies from unauthorised intentional human activity, it is necessary to ensure that they are designed in such a way as to meet the essential functionality requirement of the physical protection system (PPS). In this case, the VSS, as one of the alarm systems, should perform the function of early intrusion detection. The verification of the functionality of the PPS is possible using a software tool to model and simulate various intrusion scenarios. This article provides an example of the use of the SATANO software evaluation tool. The VSS enables multiple applications, such as monitoring, detection, knowledge, and identification. In this paper, the defined current standardised requirements for the design of VSSs in tunnels are considered from the point of view of their possible use for intelligent video analysis, enabling the recognition of various risk situations (e.g., faults or accidents of vehicles). Using the software tool, IP Video Design Tool, the requirements for the design of cameras in tunnels are assessed and adapted from the perspective of the use of intelligent video analysis. In the event that there is a requirement to use the VSS during emergency situations (e.g., fire), it is necessary to assess the operating conditions and period of time through which the VSS would operate in a given tunnel. This article presents the results of the simulation of the spread of a fire in a tunnel and its impact on the operation of the VSS.

CFD simulations of instantaneously released liquefied gas in urban areas: A case study of LPG tank truck accident in Wenling, China

The accidental release and ignition of flammable liquefied gas can cause catastrophic events, such as flash fires, vapor cloud explosions, and boiling liquid expanding vapor explosion, which severely endanger urban residents and the environment. In the current study, a method for simulating liquefied gas instantaneous release accidents was established to explore the vapor cloud diffusion behavior in urban areas. The rare liquefied petroleum gas instantaneous release accident in Wenling, China is considered as a test case. To this end, an instantaneous release source model that considers the gas phase, liquid pool, and droplets was developed. The CFD model was validated using the damage distribution at the accident site. The simulation results revealed that droplets in the release source, terrains, and large obstacles significantly affected the dispersion behavior and extension distance of the vapor cloud. The evaporation of droplets resulted in a mushroom-shaped cloud. In addition, when the cloud was ignited, the area covered by the LFL was 1.94 and 2.07 times larger in the cases with droplets than those without. The method developed in this study is applicable to developing hazardous chemical transportation and emergency response measures in urban environments to maintain the sustainable cities development.

Accurate Prediction Approach of SOH for Lithium-Ion Batteries Based on LSTM Method

The deterioration of the health state of lithium-ion batteries will lead to the degradation of the battery performance, the reduction of the maximum available capacity, the continuous shortening of the service life, the reduction of the driving range of electric vehicles, and even the occurrence of safety accidents in electric vehicles driving. To solve the problem that the traditional battery management system is difficult to accurately manage and predict its health condition, this paper proposes the mechanism and influencing factors of battery degradation. The battery capacity is selected as the characterization of the state of health (SOH), and the long short-term memory (LSTM) model of battery capacity is constructed. The intrinsic pattern of capacity degradation is detected and extracted from the perspective of time series. Experimental results from NASA and CALCE battery life datasets show that the prediction approach based on the LSTM model can accurately predict the available capacity and the remaining useful life (RUL) of the lithium-ion battery.

Exploring determinants of log truck accidents resulting in injury or fatality in the Northwest United States between 2015-2019 using Motor Carrier Management Information System data

ABSTRACT Log truck drivers represent a high-risk yet understudied worker population. Logging, more generally, is known to be one of the most dangerous industries in the country, but little is known about injury and fatality rates among log truck drivers specifically. Using data from the Motor Carrier Management Information System (MCMIS), this study aims to characterize log truck crashes in Washington, Oregon, Idaho, and Montana. Using multiple logistic regression, we estimated the odds of a crash resulting in an injury or fatality by environmental and structural conditions at the time of each crash. Results indicate that the presence of a positive median barrier is strongly associated with a decreased odds of injury or fatality for log truck crashes (odds ratio (OR) = 0.45, p = 0.03). An increased number of vehicles involved in the crash was significantly associated with an increased odds of injury or fatality (OR = 1.32, p = 0.01). Crashes occurring in Washington or Oregon had significantly decreased odds of resulting in an injury or fatality, in comparison to Idaho and Montana (OR = 0.14, p < 0.001; OR = 0.53, p = 0.01, respectively). These results indicate that the presence of highway safety measures and a state-approved OSHA plan may be beneficial in decreasing the odds of injury or fatality in log truck crashes.
