Skin regeneration is a life-saving need for many patients, whom list is stretched from burn victims to motor-car accidents. Spraying cells, either keratinocytes or stem cells, were associated with variable results and, in many cases, unfavorable outcomes. As the spatial configuration of the skin is distinctive, many trials investigated the bio-printing or the construction of three dimensional skin models where different layers of the skin were preserved. Although some of these models showed the histological configuration of the skin, their acceptance by the wound was questionable as a consequence of delayed vascularization...

This study aimed at identifying and comparing subjective risk perception regarding two different violent situations in urban roads: traffic accidents (i.e. crashes) and robberies. A robbery consists of subtracting something from someone, while seriously threatening the victim, or using violence. Robberies can be perpetrated either with or without the use of a weapon. This study was carried out in the city of Uberlândia, a medium size city in the state of Minas Gerais, south-east Brazil. A total of 383 people was interviewed at home in two boroughs of Uberlândia, using a questionnaire divided in five parts: a) personal information; b) description of crash involvement; c) description of robbery involvement; d) the chance of being involved in a crash and in a robbery within the next three years; e) willingness to pay for more safety in traffic or for more security against robberies; f) what causes more damage or harm to society, crashes or robberies...

OBJECTIVE: Public attitudes and stigma toward epilepsy may limit patient motivation for treatment and participation in social activities. Stigma research requiring individuals to report personal beliefs is useful but is subject to social desirability bias. Self-reporting methods often do not capture implicit attitudes; therefore, in this study, implicit stigma was measured using the implicit association test (IAT), which is a word sorting task to minimize this bias. Recently, in Japan, several serious car accidents caused by people with epilepsy (PWE) resulted in pedestrian fatalities...

Traffic accidents are the leading cause of hospitalization in adolescence, with the 18-24-year-old age group accounting for 23% of deaths by traffic accidents. Recurrence rate is also high. One in four teenagers will have a relapse within the year following the first accident. Cognitive impairments known in adolescence could cause risky behaviors, defined as repetitive engagement in dangerous situations such as road accidents. Two categories of factors seem to be associated with traffic accidents: (1) factors specific to the traffic environment and (2) "human" factors, which seem to be the most influential...

BACKGROUND: Most young people killed in road crashes are known as vulnerable road users. A combination of physical and developmental immaturity as well as inexperience increases the risk of road traffic accidents with a high injury severity rate. Understanding injury mechanism and pattern in a group of young road users may reduce morbidity and mortality. This study analyzes injury patterns and outcomes of young road users compared to adult road users. The comparison takes into account different transportation related injury mechanisms...

To prevent car accidents, it is important to evaluate the thermal stability of tire rubbers, such as natural rubber (NR), butadiene rubber (BR), and styrene-butadiene rubber (SBR). Controlling the glass transition temperature (Tg) is the main factor for obtaining desirable thermal stability. Here, we developed an optimized equation for the prediction of the Tg of the various rubber systems using molecular dynamics (MD) simulations. We modeled a random copolymer system, blended monomers, and calculated the Tg of butadiene isomers in each composition...

In-vehicle data recorders (IVDR) have been found to facilitate safe driving and are highly valuable in accident analysis. Nevertheless, it is not easy to convince drivers to use them. Part of the difficulty is related to the "Big Brother" concern: installing IVDR impairs the drivers' privacy. The "Big Brother" concern can be mitigated by adding a turn-off switch to the IVDR. However, this addition comes at the expense of increasing speed variability between drivers, which is known to impair safety. The current experimental study examines the significance of this negative effect of a turn-off switch under two experimental settings representing different incentive structures: small and large fines for speeding...

BACKGROUND: Isolated small bowel perforation following blunt abdominal trauma (BAT) is an uncommon situation with high morbidity and mortality rates, and delayed small bowel perforation is even rarer. The pathophysiology of this condition is not clear in all cases. To the best of our knowledge, this is the first case report of delayed small bowel perforation following BAT with extensive portomesenteric vein gas. CASE REPORT: A 33-year-old male patient was admitted to the emergency department after a car accident...

Involvement of sport utility vehicles (SUV) in accidents especially with children is of increasing importance. Studies have indicated a more risky behavior in SUV drivers. We conducted an observational study focusing on traffic violations, car type, and the gender of the driver in Vienna. The study was conducted on five weekdays at the beginning of school term. Three busy intersections were selected.Drivers of 43,168 normal cars and 5653 SUVs were counted at the intersections during the observation period...

In order to avoid car crashes, active safety systems are becoming more and more important. Many crashes are caused due to driver drowsiness or mobile phone usage. Detecting the drowsiness of the driver is very important for the safety of a car. Monitoring of vital signs such as respiration rate and heart rate is important to determine the occurrence of driver drowsiness. In this paper, robust vital signs monitoring through impulse radio ultra-wideband (IR-UWB) radar is discussed. We propose a new algorithm that can estimate the vital signs even if there is motion caused by the driving activities...

In response to the accident at Tokyo Electric Power Company's Fukushima Dai-ichi Nuclear Power Plant (FDNPP), vehicle-borne monitoring was used to map radiation levels for radiological protection of the public. By convention measurements from vehicle-borne surveys are converted to the ambient dose equivalent rate at 1 m height in the absence of the vehicle. This allows for comparison with results from other types of survey, including surveys with hand-held or airborne instruments. To improve the accuracy of the converted results from vehicle-borne surveys, we investigated combining measurements from two detectors mounted on the vehicle at different heights above the ground...

Myopericytoma is a slow-growing, benign soft tissue neoplasm that arises from perivascular smooth muscle cells. This tumor is a rare entity itself, but it is only scarcely mentioned in the literature occurring secondary to trauma. The authors report a 21-year-old male patient who presented with a pulsatile mass in the medial canthal area where he had experienced previous trauma from a car accident 1-year prior. The mass was excised and histopathology revealed myopericytoma. This clinical report adds to the limited body of evidence supporting trauma as an etiology for this rare tumor...

INTRODUCTION: Traumatic experiences that are varied in type and severity may lead to the development of Posttraumatic Stress Disorder (PTSD). Some trauma types present a higher conditional risk for PTSD owing to their nature and impact on growth and functioning. Few studies have investigated the conditional risk of PTSD in clinic referred adolescents in low- and middle-income countries. The aim of the study was to determine the conditional risk for PTSD based on various trauma types (car accidents, other serious accidents, fires, witnessing a natural disaster, witnessing a violent crime, being confronted with traumatic news, witnessing domestic violence, physical abuse and sexual abuse) and to stratify risk by gender...

A 27-year-old woman sustained a blunt chest trauma after a car accident. Computed tomography revealed tension pneumopericardium, bilateral pneumothorax, and a suspected rupture of the left main bronchus. Emergent pericardial needle aspiration was successfully performed. Bronchial amputation was confirmed by bronchofiberoscopy. Despite total detachment of the distal part of the bronchial tree, the ventilation of the left lung was maintained without air leakage by use of pleural drains. Bronchial obturation resulted from the injury, and was effectively treated by bronchoscopic sputum suction at the distal end of the bronchus...

Currently, there is no information about the possibility of developing clinical symptoms after whiplash in double transverse foramen subjects. Our aim was to test whether subjects with double transverse foramen have an increased risk of presenting with an acute headache, dizziness, vertebral artery dissection, and vomiting after whiplash.We recorded the absence/presence of double transverse foramen, and the absence/presence of neck pain, acute headache, dizziness, vertebral artery dissection, and vomiting in 85 patients who had suffered whiplash injuries in car rear-end impacts in road traffic accidents...

Post-traumatic stress disorder (PTSD) is a debilitating illness that imposes significant emotional and financial burdens on military families. The understanding of PTSD etiology remains elusive; nonetheless, it is clear that PTSD is manifested by a cluster of symptoms including hyperarousal, reexperiencing of traumatic events, and avoidance of trauma reminders. With these characteristics in mind, several rodent models have been developed eliciting PTSD-like features. Animal models with social dimensions are of particular interest, since the social context plays a major role in the development and manifestation of PTSD...
