“…The present finding that the MAIS (other than the face) was higher in motorcyclists than in bicyclists also supports the theory that motorcyclists suffer from greater force at collision than do bicyclists. Furthermore, this is in accordance with the findings of a previous autopsy study of bicyclists and motorcyclists 18 . In the present study, ORIF was employed in 10.8% of patients, which is lower than the previously reported incidences that have ranged from 28% to 60% 11,19,20 .…”

Background/Aim Because bicyclists and motorcyclists with oral and maxillofacial injuries often suffer from disabilities requiring long‐term treatment, reducing the severity of such injuries is a valuable objective for improving these people's quality of life (QOL). The aims of this study were, first, to present the prevalence and patterns of oral and maxillofacial injuries of bicyclists and motorcyclists and to compare the features of these injuries and, second, to determine the factors contributing to long‐term hospitalization for these patients and to propose effective preventive measures. Material and Methods This was a single‐center retrospective analysis. Hospital records from 2011 through 2018 were reviewed for all patients who had sustained oral and maxillofacial injuries in bicycle or motorcycle collisions and had presented at a university hospital which was the only hospital in the region attended 24 hours per day by oral and maxillofacial surgeons. Characteristics of the oral and maxillofacial injuries, injury severity, and factors influencing the length of hospitalization were examined. Results Records of 130 patients (82 bicyclists and 48 motorcyclists) with a mean age of 28.0 years were analyzed. Thirty‐three patients (25.4%) had maxillofacial fractures, with 41 fracture lines while 103 patients (79.2%) had dental injuries and 57 patients (43.8%) had soft‐tissue injuries. The distribution and prevalence of oral and maxillofacial injuries were similar for bicyclists and motorcyclists. However, motorcyclists had significantly higher Abbreviated Injury Scale (AIS) scores for facial injuries and the maximum AIS score than did bicyclists. According to a multiple regression analysis, the number of fracture lines and the requirement for intermaxillary fixation were independent factors influencing long‐term hospitalization (standard regression coefficients: 6.795 and 6.715, respectively; P < .001). Conclusions The number of fracture lines and the use of intermaxillary fixation were independent factors influencing long‐term hospitalization of both bicyclists and motorcyclists with oral and maxillofacial injuries.

“…Alcohol consumption causes decreased visual ability, increased reaction time, impaired concentration and performance of tasks that require divided attention, in addition to an increased risk of collision. 5 However, there are controversies about the influence of alcohol on the severity of injuries caused by traffic accidents. 6 , 7 Tulloh and Collopy 8 report a positive association between alcohol intoxication, impact velocity, Injury Severity Score (ISS) and a higher risk of death.…”

Objective: To evaluate the correlation between blood alcohol levels and the severity of injuries assessed by the Injury Severity Score (ISS) in patients who were victims of traffic accidents admitted to the Hospital das Clínicas of the Faculty of Medicine of the University of São Paulo (HCFMUSP). Methods: Cross-sectional study carried out between July 2018 and June 2019, at the Central Emergency Room of the Hospital das Clínicas of the Faculty of Medicine of the University of São Paulo (PSC-HCFMUSP). A total of 172 hospitalized patients victims of traffic accidents were included in this study. Blood samples were analyzed by the FMUSP Toxicology Laboratory. Results: 36 patients (20.9%) had positive BAC (≥ 0.2 g/L) with a mean of 1.21 g/L. Overall, patients had a mean age of 37.2 years old, and 136 (79.1%) were men. The ISS of the total casuistry was 15.6; regarding the external cause, the motorcycle was ranked first with 100 cases (58.1%), and drivers were the majority with 57.4% of the sample. Conclusion: There was no correlation between the severity of the injuries and the blood alcohol levels of traffic accident victims admitted to a reference hospital. Level of Evidence II, Cross-Sectional Study.

“…They also found that the prevalence of intoxicated bicyclists was more common during night, increasing from 7.7% at 6 PM to 89% after 1 AM in a student town. In a forensic autopsy study by Takeda et al (2020), alcohol was found in the blood of 52% of the 14 investigated bicyclists. The mean blood alcohol concentration of these bicyclists was 1.59 mg/mL.…”

The number of bicycling fatalities was 19 450 between 2010 and 2018 in Europe. The number of bicyclists killed when intoxicated by alcohol is harder to establish given the lack of reliable data. In Sweden, drunk bicycling is socially acceptable and legal (unless reckless). This experiment aimed to investigate how alcohol intoxication affect bicycling stability performance, executive functions, and self-rated ability. The experiment was completed on a wide treadmill that allowed control of several influencing factors such as speed and physical effort. Intoxicated and sober participants bicycled on the treadmill for five 10 minute sessions. Alcohol as administered incrementally to reach a target breath alcohol concentration level of 0.8‰. Stability decreased with intoxication; especially roll rate measurements were identified as being adequate indicators of bicycling instability. Executive function was negatively affected, and ability ratings decreased due to intoxication. The intoxicated participants were aware of their reduced ability to bicycle in a safe manner on a group level but not on an individual level. However, this insight does not affect their intention to bicycle intoxicated.
