The purpose of this study was to calculate the prevalence of mandibular fractures based on their causes and locations. MATERIALS AND METHOD: A systematic search of 3 electronic databases from January 2010 and January 2020 was conducted following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines...

An 18-year-old female presented to the emergency department after a motor vehicle collision. Initial imaging revealed a liver laceration. Subsequent labs showed significantly elevated prothrombin time, international normalized ratio, and activated partial thromboplastin time. Thromboelastography demonstrated a flatline tracing. The patient denied use of anticoagulation but admitted to synthetic cannabinoid use. It was believed the patient had taken synthetic cannabinoid contaminated by brodifacoum. She was therefore given prothrombin complex concentrate and vitamin K with blood products...

An 18-year-old male subject was referred to our MRI scanning center, by an orthopedic surgeon, for a swelling over the plantar region of the foot. He had been in a motor vehicle accident a few weeks back, with no evidence of fracture at the time of injury. In subsequent weeks, he developed a swelling over his foot. MRI showed the presence of a fluid intensity lesion in the subdermal and dermal layers of his foot. Unguarded motor vehicle accidents often tend to cause severe injuries. Sometimes, they even need operative management since a motor vehicle collision is a high-impact accident...

INTRODUCTION: Despite evidence showing higher fatality rates in freight-related crashes, there has been limited exploration of their spatial distribution and factors associated with such distribution. This gap in the literature primarily stems from the focus of existing studies on micro-level factors predicting the frequency or severity of injuries in freight crashes. The present study delves into the factors contributing to freight crashes at the neighborhood level, particularly focusing on different types of freight crashes: collisions involving a freight vehicle and a passenger vehicle, crashes between freight vehicles, and freight vehicle-non-motorized crashes...

INTRODUCTION: The risk of motor vehicle-bicyclist crashes and fatalities is greater during nighttime than daytime lighting conditions, even though there are fewer cyclists on roadways at night. Vehicle Adaptive Headlamp Systems (AHS) aim to increase the visibility of bicyclists for drivers by directing a spotlight to illuminate bicyclists on or near the roadway. AHS technology also serves to alert bicyclists to the approaching vehicle by illuminating the road beneath the rider and by projecting a warning icon on the roadway...

OBJECTIVES:  Investigating patterns among the outcomes of patients involved in motor vehicle accidents (MVAs) can provide information necessary to guide targeted interventions to improve road traffic safety. Our purpose is to identify any differences between passenger and driver injury severity and overall clinical course after MVAs. METHODS:  We performed a retrospective review and analysis of 3,693 patients involved in MVAs from 2016 to 2021. We divided the data into two groups, drivers and passengers, and compared the Injury Severity Score (ISS), Revised Trauma Score (RTS) on admission, days in the Intensive Care Unit (ICU), length of hospital stay (LOS), post Emergency Department (ED) disposition, discharge (DC) disposition, and signs of life on arrival (SOLA) to the ED...

The extremities are the important anatomical regions that are disproportionately injured during road traffic accidents in poor and medium-income countries. The data regarding extremity injuries, particularly in pillion passengers, are minimal globally. We analyzed the pattern of extremity injuries and their association with various parameters such as collision type, seating position, road type, and type of vehicle. This was a hospital-based cross-sectional study. The pillion riders of fatal motorized 2-wheeler road accident cases that were subjected to autopsy were studied over a period of 2 years...

The rupture of the gravid uterus is a rare complication of trauma. It is reported in less than one percent of pregnant women who are victims of road accidents. The authors report the case of a 26-year-old nulliparous patient presented with a uterine rupture resulting in fetal death at 32 weeks of gestation following a nonpenetrating abdominal trauma in a road traffic accident. An extreme emergency operation and abdominal laparotomy confirmed the imaging findings and led to conservative treatment of the uterus and a splenectomy...
