To investigate the differences of the head impact responses between bicyclists and motorcyclists in vehicle collisions. A series of vehicle-bicycle and vehicle-motorcycle lateral impact simulations on four vehicle types at seven vehicle speeds (30, 35, 40, 45, 50, 55 and 60 km/h) and three two-wheeler moving speeds (5, 7.5 and 10 km/h for bicycle, 10, 12.5 and 15 km/h for motorcycle) were established based on PC-Crash software. To further comprehensively explore the differences, additional impact scenes with other initial conditions, such as impact angle (0, π/3, 2π/3 and π) and impact position (left, middle and right part of vehicle front-end), also were supplemented...

Motorcycle crashes constitute a very high proportion of the overall motor vehicle fatalities in the United States, and many studies have examined the influential factors under various conditions. However, research on the impact of weather conditions on the motorcycle crash severity is not well documented. In this study, we examined the impact of weather conditions on motorcycle crash injuries at four different severity levels using San Francisco motorcycle crash injury data. Five models were developed using Full Bayesian formulation accounting for different correlations commonly seen in crash data and then compared for fitness and performance...

The research described in this paper explored the factors contributing to the injury severity resulting from the motorcycle at-fault accidents in rural and urban areas in Alabama. Given the occurrence of a motorcycle at-fault crash, random parameter logit models of injury severity (with possible outcomes of fatal, major, minor, and possible or no injury) were estimated. The estimated models identified a variety of statistically significant factors influencing the injury severities resulting from motorcycle at-fault crashes...

Cerebrospinal fluid fistula caused by head trauma is a potentially dangerous problem and precise localization and radical treatment are necessary. We present a case of a patient with Panfacial fracture caused by a motorcycle accident, resulting in a cerebrospinal fluid leakage. The correct diagnosis was realized by computed tomography and auxiliary tests. The successful treatment can be confirmed with the support of radionuclide cisternography examination.

INTRODUCTION: Syringomyelia is a disorder in which a cyst, or syrinx, develops within the spinal cord. Historically, syringomyelia in post-traumatic spinal cord injury has been uncommon; however, its diagnosis has been increasing due to the advances in medical technology. Syringomyelia that involves the entire spinal cord, or holocord, is rare after traumatic spinal cord injury, with only a few cases reported in the literature. CASE PRESENTATION: We present a case of a 57-year-old male who had a motorcycle accident 30 years ago resulting in a spinal cord injury, who presented a rapid decline in the function of his left upper extremity...

This study aimed to explore the combination of factors and circumstances that could increase the likelihood of a pedestrian crash to be fatal. Six pedestrian crash clusters identified in our previous study on 34,178 crashes occurred in Iran, were employed in the current work and the association rules technique was used as the analysis tool. Based on the results, jaywalking or waiting beside the road on poorly illuminated locations of those segments of rural roads that pass through residential/agricultural districts substantially increased the fatality risk of pedestrian (Lift = 3...

Keloids are caused by excessive scar formation that leads to scar growth beyond the initial scar boundaries. Keloid formation and progression is promoted by mechanical stress such as skin stretch force. Consequently, keloids rarely occur in paralyzed areas and areas with little skin tension, such as the periauricular region. Therefore, periauricular incision is commonly performed for face lifts. We report a rare case of keloids that arose from face-lift scars in a patient with bilateral facial nerve paralysis...

INTRODUCTION: In the treatment of Gustilo Type 3B open tibial fractures, it is important to perform soft tissue reconstruction and bone reconstruction simultaneously. Gastrocnemius muscle and soleus muscle flaps are generally used as rotational flaps for the tibia. The distal third of the tibia can often not be covered with the gastrocnemius muscle and soleus muscle flaps. Treatment distal to the distal third of the tibia is difficult because fewer flap options are available. In the present report, we describe our experience with a Gustilo Type 3B open tibial fracture treated by gastrocnemius muscle and soleus muscle flaps, along with an additional proximally based flexor hallucis longus flap, which is a rare procedure...

Use of Daytime Running Lights (DRL) is mandatory in many countries for motorcycles, and in some for cars. However, in developing countries, DRLs may be optional or compliance low. The effect of car or motorcycle headlights and lighting conditions on Malaysian drivers' ability to perceive and judge the safety of pulling out was investigated. Stimuli were photographs depicting either daytime or nighttime taken at a T-junction with approaching vehicles with headlights on or off. Headlights improved drivers' ability to perceive cars and motorcycles in the nighttime photographs but not the daytime photographs, although this could be due to the bright weather in the photographs...
