AbstractThe present review paper aims to update the definition and classification of cerebral concussion, highlighting its pathophysiological mechanisms. The high prevalence of cerebral concussion in emergency rooms around the world makes it necessary to know its proper management to avoid its late sequelae, which traditionally compromise cognitive aspects of behavior. New evidence on potential neuroprotective treatments is being investigated.

ObjectiveTo analyze the history of self-reported head impacts, prevalence of post-concussion symptoms and performance in motor coordination tests in amateur handball athletes.BackgroundHandball is a contact sport where athletes can suffer collisions through different mechanisms and there are few published data about brain concussion in handball, mainly in Brazilian athletes.Design/MethodsAmateur male athletes aged between 18 and 35 years, with 4–6 hours of training per week and an average of 12.5 games in the last 6 months were evaluated regarding to the head impact history during handball games and practices. The athletes were also evaluated regarding of the most common kind of impact mechanism, loss of consciousness (LOC), reported cervical injury (pain and decreased range of motion), symptoms prevalence and their severity using the Post Concussion Symptom Scale (PCSS), time to execution of single-task tandem gait (TG) and performance in the Finger-to-Nose test (>4 seconds to perform five successive finger to nose repetitions was considered abnormal).ResultsSix athletes reported direct impacts on the head while playing handball. Falls, elbow to the head, trunk to the head and hit by the ball were the most reported mechanisms of head impact in handball athletes. Two athletes reported LOC and all of them denied cervical injury after trauma. Regarding the PCSS score, three athletes had a score between 6-21 and five athletes had a 22–84 score. The most reported symptoms were sleeping more than usual, drowsiness, fatigue, changes in behavior (nervousness, feeling more emotional and irritability), trouble falling asleep and dizziness. However, athletes shown a normal performance in the single task TG (14.6–17.2 seconds) compared to normative data and three athletes shown altered performance on the Finger-to-Nose test.ConclusionsAmateur handball athletes had significant scores of PCSS mainly related to sleep, emotional and possibly to the vestibular function.

Severity Of Injury

A typical occurrence in emergency rooms is traumatic brain injury (TBI) resulting from head trauma which is normally responsible for far more than 1 million visits per year. The magnitude of TBIs varies from mild, intermittent symptoms to longer periods of altered states of consciousness. The precise mechanism of concussion is indefinite. In serious brain trauma, Axon tearing is expected, but there is no evidence for this concussion process. Most concussion patients improve rapidly and entirely. Concussion management is usually supportive and some cases may need hospital admissions and ICU care according to severity of injury and related symptoms.

Pedestrian Crashes

For study of car-pedestrian crashes, it is two common methods that can be employed: conducting crash tests with mechanical dummies and simulating car crashes on computer. The former is a traditional way and gives good results compared with real life car impact; however, its disadvantage is very expensive test equipment and generally more time-consuming than the latter because after every crash test, experimental vehicles as well as dummies need repairing to be ready for the next experiments. Therefore, crash test simulation using finite-element method is more and more popular in the automobile industry because of its feasibility and cost saving. The majority of finite element dummy models used in crash simulation. Particularly, it is popular to use Hybrid III 50th dummy model which is built based on fiftieth percentile male (equal in height and weight of the average North American). Thus, it is necessary to develop a scaling algorithm to scale a reference dummy size into a desired one without rebuilding the entire model. In this paper, the Hybrid III dummy model provided by LS-DYNA software is scaled to suit Vietnamese biomechanical characteristics. Scaling algorithm comprises dummy geometry, inertial properties and joint properties is utilized. In order to estimate level of head injury – brain concussion by using numerical simulation, the correlation between Head Injury Criterion (HIC) and Abbreviated Injury Scale (AIS) is introduced. In addition, the Hybrid III dummy model in crashworthiness simulation is presented in key frame picture. Numerical simulation approach is validated by comparing results of head acceleration and HIC obtain from this study with experimental data and numerical simulation results in other publication

Vegetative Status

Peculiarities of infringement of the vegetative status in children, suffered concussion of brain are revealed. Disintegration of activity of vegetative systems was displayed by suppression of ergotropic link, causing insufficient vegetative reaction and inadequate vegetative provision of activity. Interrelation of character of vegetative reaction with terms of remote period was observed. Influence of age of the children, character of medical history, degree of clinical compensation was shown.
