Spinal cord injuries (SCIs) related to cervical spine (C-spine) fractures can cause significant morbidity and mortality. Aggressive treatment often required to manage instability associated with C-spine fractures is complicated and hazardous in the elderly population. To determine the mortality rate of elderly patients with SCIs related to C-spine fractures and identify factors that contribute toward a higher risk for negative outcomes. Retrospective cohort study at two Level 1 trauma centers. Thirty-seven consecutive patients aged 60 years and older who had SCIs related to C-spine fractures. Level of injury, injury severity, preinjury medical comorbidities, treatment (operative vs. nonoperative), and cause of death. Hospital medical records were reviewed independently. Baseline radiographs and computed tomography or magnetic resonance imaging scans were examined to permit categorization according to the mechanistic classification by Allen and Ferguson of subaxial C-spine injuries. Univariate logistic regression analyses were performed to identify factors related to in-hospital mortality and ambulation at discharge. There were no funding sources or potential conflicts of interest to disclose. The in-hospital mortality rate was 38%. Respiratory failure was the leading cause of death. Preinjury medical comorbidities, age, and operative versus nonoperative treatment did not affect mortality. Injury level at or above C4 was associated with a 7.1 times higher risk of mortality compared with injuries below C4 (p=.01). Complete SCI was associated with a 5.1 times higher risk of mortality compared with incomplete SCI (p=.03). Neurological recovery was uncommon. Apart from severity of initial SCI, no other factor was related to ambulatory disposition at discharge. In this elderly population, neurological recovery was poor and the in-hospital mortality rate was high. The strongest risk factors for mortality were injury level and severity of SCI. Although each case of SCI

The neurobiological mechanisms that underlie facial affect recognition deficits after traumatic brain injury (TBI) have not yet been identified. Using functional magnetic resonance imaging (fMRI), study aims were to 1) determine if there are differences in brain activation during facial affect processing in people with TBI who have facial affect recognition impairments (TBI-I) relative to people with TBI and healthy controls who do not have facial affect recognition impairments (TBI-N and HC, respectively); and 2) identify relationships between neural activity and facial affect recognition performance. A facial affect recognition screening task performed outside the scanner was used to determine group classification; TBI patients who performed greater than one standard deviation below normal performance scores were classified as TBI-I, while TBI patients with normal scores were classified as TBI-N. An fMRI facial recognition paradigm was then performed within the 3T environment. Results from 35 participants are reported (TBI-I = 11, TBI-N = 12, and HC = 12). For the fMRI task, TBI-I and TBI-N groups scored significantly lower than the HC group. Blood oxygenation level-dependent (BOLD) signals for facial affect recognition compared to a baseline condition of viewing a scrambled face, revealed lower neural activation in the right fusiform gyrus (FG) in the TBI-I group than the HC group. Right fusiform gyrus activity correlated with accuracy on the facial affect recognition tasks (both within and outside the scanner). Decreased FG activity suggests facial affect recognition deficits after TBI may be the result of impaired holistic face processing. Future directions and clinical implications are discussed.

Recent studies have helped identify multiple factors affecting increased risk for substance use disorders (SUDs) following traumatic brain injury (TBI). These factors include age at the time of injury, repetitive injury and TBI severity, neurocircuits, neurotransmitter systems, neuroinflammation, and sex differences. This review will address each of these factors by discussing 1) the clinical and preclinical data identifying patient populations at greatest risk for SUDs post-TBI, 2) TBI-related neuropathology in discrete brain regions heavily implicated in SUDs, and 3) the effects of TBI on molecular mechanisms that may drive substance abuse behavior, like dopaminergic and glutamatergic transmission or neuroimmune signaling in mesolimbic regions of the brain. Although these studies have laid the groundwork for identifying factors that affect risk of SUDs post-TBI, additional studies are required. Notably, preclinical models have been shown to recapitulate many of the behavioral, cellular, and neurochemical features of SUDs and TBI. Therefore, these models are well suited for answering important questions that remain in future investigations. Copyright © 2017 Elsevier Ltd. All rights reserved.

Does the cause of the mild traumatic brain injury affect the expectation of persistent postconcussion symptoms and psychological trauma?

Science.gov (United States)

Sullivan, Karen A; Wade, Christina

2017-05-01

A controlled experiment of the effect of injury cause on expectations of outcome from mild traumatic brain injury (TBI) was conducted. Ninety-three participants were randomly assigned to one of four conditions. The participants read a vignette that described a mild TBI (with fixed injury parameters) from a different cause (sport, domestic assault, fall, or motor vehicle accident). The effect of the manipulation on expectations of persistent postconcussion symptoms and psychological trauma was assessed with standard measures and a novel "threat-to-life" measure. The Kruskal-Wallis H test for group differences revealed a significant but selective effect of group on symptom and trauma outcomes (ŋ 2 s ≥ .10; large effects). Post hoc pairwise tests showed that, in most cases, there was an expectation of a worse outcome following mild TBI from a domestic assault than from the other causes (small-to-medium effects). Expectations were selectively altered by an experimental manipulation of injury cause. Given that expectations of outcome are known to affect mild TBI prognosis, the findings suggest the need for greater attention to injury cause.

Most ballet dancers will suffer at least one injury a year. There are numerous causes of injury in dance, and while many investigators have documented risk factors such as anatomical characteristics, past medical history, menstrual history, dance experience, length of dance training, fatigue, and stress, risk factors related to body characteristics and nutrient intake, levels of conditioning, or physical fitness parameters have only recently received the same amount of attention. The aim of the present study was, therefore, to investigate correlations between ballet injury and body fat percentage, active and passive flexibility, lower limb power, upper body and core endurance, and aerobic capacity. Low levels of aerobic fitness were significantly associated with many of the injuries sustained over a 15-week period (r=.590, p=0.034), and body fat percentage was significantly associated with the length of time a dancer was forced to modify activity due to injury (r=-.614, p=0.026). This information may be of benefit to dancers, teachers, physical therapists and physicians in dance schools and companies when formulating strategies to prevent injury.

We investigated the effect of leaf age on the response of net photosynthesis (A), stomatal conductance (g{sub wv}), foliar injury, and leaf nitrogen concentration (N{sub L}) to tropospheric ozone (O{sub 3}) on Prunus serotina seedlings grown in open-plots (AA) and open-top chambers, supplied with either carbon-filtered or non-filtered air. We found significant variation in A, g{sub wv}, foliar injury, and N{sub L} (P < 0.05) among O{sub 3} treatments. Seedlings in AA showed the highest A and g{sub wv} due to relatively low vapor pressure deficit (VPD). Older leaves showed significantly lower A, g{sub wv}, N{sub L}, and higher foliar injury (P < 0.001) than younger leaves. Leaf age affected the response of A, g{sub wv}, and foliar injury to O{sub 3}. Both VPD and N{sub L} had a strong influence on leaf gas exchange. Foliar O{sub 3}-induced injury appeared when cumulative O{sub 3} uptake reached 8-12 mmol m{sup -2}, depending on soil water availability. The mechanistic assessment of O{sub 3}-induced injury is a valuable approach for a biologically relevant O{sub 3} risk assessment for forest trees. - Ozone effects on symptom development and leaf gas exchange interacted with leaf age and N-content on black cherry seedlings.

During top-level international athletics championships, muscle injuries are frequent. To analyse the incidence and characteristics of muscle injuries and hamstring muscle injuries (hamstring injuries) occurring during top-level international athletics championships. During 16 international championships held between 2007 and 2015, national medical team and local organising committee physicians reported daily all injuries on a standardised injury report form. Only muscle injuries (muscle tears and muscle cramps) and hamstring injuries have been analysed. 40.9% of all recorded injuries (n=720) were muscle injuries, with 57.5% of them resulting in time loss. The overall incidence of muscle injuries was higher in male athletes than female athletes (51.9±6.0 vs 30.3±5.0 injuries per 1000 registered athletes, respectively; RR=1.71; 95% CI 1.45 to 2.01). Muscle injuries mainly affected the thigh (52.9%) and lower leg (20.1%), and were mostly caused by overuse with sudden onset (38.2%) and non-contact trauma (24.6%). Muscle injury risk varied according to the event groups. Hamstring injuries represented 17.1% of all injuries, with a higher risk in male compared to female athletes (22.4±3.4 vs 11.5±2.6 injuries per 1000 registered athletes, respectively; RR=1.94; 95% CI 1.42 to 2.66). During international athletics championships, muscle injury is the principal type of injury, and among those, the hamstring is the most commonly affected, with a two times higher risk in male than female athletes. Athletes in explosive power events, male athletes and older male athletes, in specific were more at risk of muscle injuries and hamstring injuries. Injury prevention strategies should be sex-specific. Published by the BMJ Publishing Group Limited.

Revell, Maria A; Pugh, Marcia A; McGhee, Melanie

2018-03-01

The abdomen is a big place even in a small person. Gastrointestinal trauma can result in injury to the stomach, small bowel, colon, or rectum. Traumatic causes include blunt or penetrating trauma, such as gunshot wounds, stabbings, motor vehicle collisions, and crush injuries. Nontraumatic causes include appendicitis, Crohn disease, cancer, diverticulitis, ulcerative colitis, blockage of the bowel, and chemotherapy. The mechanism of injury will affect both the nature and severity of any resulting injuries. Treatment must address the critical and emergent nature of these injuries as well as issues that affect all trauma situations, which include management of hemodynamic instability.

Deficits in theory of mind (ToM) are common after neurological insult acquired in the first and second decade of life, however the contribution of large-scale neural networks to ToM deficits in children with brain injury is unclear. Using paediatric traumatic brain injury (TBI) as a model, this study investigated the sub-acute effect of paediatric traumatic brain injury on grey-matter volume of three large-scale, domain-general brain networks (the Default Mode Network, DMN; the Central Executive Network, CEN; and the Salience Network, SN), as well as two domain-specific neural networks implicated in social-affective processes (the Cerebro-Cerebellar Mentalizing Network, CCMN and the Mirror Neuron/Empathy Network, MNEN). We also evaluated prospective structure-function relationships between these large-scale neural networks and cognitive, affective and conative ToM. 3D T1- weighted magnetic resonance imaging sequences were acquired sub-acutely in 137 children [TBI: n = 103; typically developing (TD) children: n = 34]. All children were assessed on measures of ToM at 24-months post-injury. Children with severe TBI showed sub-acute volumetric reductions in the CCMN, SN, MNEN, CEN and DMN, as well as reduced grey-matter volumes of several hub regions of these neural networks. Volumetric reductions in the CCMN and several of its hub regions, including the cerebellum, predicted poorer cognitive ToM. In contrast, poorer affective and conative ToM were predicted by volumetric reductions in the SN and MNEN, respectively. Overall, results suggest that cognitive, affective and conative ToM may be prospectively predicted by individual differences in structure of different neural systems-the CCMN, SN and MNEN, respectively. The prospective relationship between cerebellar volume and cognitive ToM outcomes is a novel finding in our paediatric brain injury sample and suggests that the cerebellum may play a role in the neural networks important for ToM. These findings are

Although many people with an acquired brain injury (ABI) encounter difficulties with executive functioning and memory which could negatively affect driving, few people are assessed for fitness to drive after injury. The purpose of this systematic review was to synthesize the literature on factors affecting driving and public transportation among youth and young adults with ABI, post injury. Seven databases were systematically searched for articles from 1980 to 2016. Studies were screened independently by two researchers who performed the data extraction. Study quality was appraised using the Standard Quality Assessment Criteria (Kmet) for evaluating primary research from a variety of fields. Of the 6577 studies identified in the search, 25 met the inclusion criteria, which involved 1527 participants with ABI (mean age = 25.1) across eight countries. Six studies focused on driving assessment and fitness to drive, ten on driving performance or risk of accidents and nine studies explored issues related to accessing or navigating public transportation. Quality assessment of the included studies ranged from 0.60 to 0.95. Our findings highlight several gaps in clinical practice and research along with a critical need for enhanced fitness to drive assessments and transportation-related training for young people with ABI.

Full Text Available Aquatic sports keep rising in popularity. Kitesurfing is a high-risk sport that combines aspects of several water sports. The dangers of high-risk sports have been widely studied. Kitesurfing is a relatively new water sport, and the understanding of the injuries due to its practice has not yet been largely investigated. The purpose of this study is to investigate the most common types and causes of injuries among Portuguese kitesurfers. The data was collected using a retrospective 12 months web-based questionnaire. A total of n= 87 kitesurfers, mostly from the North, showed that 75.9% have a kitesurfing initiation course and 57.5% use protective equipment. A total of 60.9% has been injured in the 12 month’s period, being the knee and the lumbar spine the most common body injury. A reasonable number of injuries occurred while performing a landing or a maneuver, being 53.9% of the injuries reported as a new injury. This 12 month’s retrospective study supports earlier studies and provides basis knowledge about the incidence of Portuguese kitesurfers injuries. The data support the benefits of physical fitness (p< 0.05 in injuries prevention.

Full Text Available Background: Epidemiologic research to learn the incidence, type, location, and severity of female soccer injuries and the risk factors for sustaining a sport injury is the first step in developing preventive policies. The aim of this study was to analyze the incidence of injuries in the population of female soccer players in Spain. Methods: The injuries incurred by 25,397 female soccer players were registered by the medical staff of the Spanish Football Federation during 1 season. A standardized medical questionnaire was used to classify the injury according to type, severity, location, and injury mechanism. A total of 2108 injuries was reported with an incidence of 0.083 injuries per player per season. Most injuries were in the lower limbs (74.0%, mainly affecting knee (30.4% and ankle joints (17.9%. Results: The proportion of injuries derived from contact with another player was higher during matches (33.7% than during training (11.4%; p  0.05. Conclusion: Most female soccer injuries were located at the knee and ankle; the injury mechanism determined the playing time lost; and the player's age did not affect injury characteristics.

Acute lung injury (ALI) is a potentially fatal disease characterized by uncontrolled hyperinflammatory responses in the lungs as a consequence of sepsis. ALI is divided into two sequential and time-dependent phases, exudative and fibroproliferative phases, with increased permeability of the alveolar barrier, causing edema and inflammation. However, there are no specific treatments for ALI. Low-power lasers have been successfully used in the resolution of acute inflammatory processes. The aim of this study was to evaluate the effects of low-power infrared laser exposure on alveolus and interalveolar septa of Wistar rats affected by ALI-induced by sepsis. Laser fluences, power, and the emission mode were those used in clinical protocols for the treatment of acute inflammation. Adult male Wistar rats were randomized into six groups: control, 10 J cm‑2, 20 J cm‑2, ALI, ALI  +  10 J cm‑2, and ALI  +  20 J cm‑2. ALI was induced by intraperitoneal Escherichia coli lipopolysaccharide (LPS). Lungs were removed and processed for hematoxylin–eosin staining. Morphological alterations induced by LPS in lung tissue were quantified by morphometry with a 32-point cyclic arcs test system in Stepanizer. Data showed that exposure to low-power infrared laser in both fluences reduced the thickening of interalveolar septa in lungs affected by ALI, increasing the alveolar space; however, inflammatory infiltrate was still observed. Our research showed that exposure to low-power infrared laser improves the lung parenchyma in Wistar rats affected by ALI, which could be an alternative approach for treatment of inflammatory lung injuries.

Mountain Biking Injuries.

Ansari, Majid; Nourian, Ruhollah; Khodaee, Morteza

With the increasing popularity of mountain biking, also known as off-road cycling, and the riders pushing the sport into extremes, there has been a corresponding increase in injury. Almost two thirds of acute injuries involve the upper extremities, and a similar proportion of overuse injuries affect the lower extremities. Mountain biking appears to be a high-risk sport for severe spine injuries. New trends of injury patterns are observed with popularity of mountain bike trail parks and freeride cycling. Using protective gear, improving technical proficiency, and physical fitness may somewhat decrease the risk of injuries. Simple modifications in bicycle-rider interface areas and with the bicycle (bike fit) also may decrease some overuse injuries. Bike fit provides the clinician with postural correction during the sport. In this review, we also discuss the importance of race-day management strategies and monitoring the injury trends.

One of many types of injuries following an earthquake is spinal cord injury (SCI) which is a life-long medically complex injury and high-cost health problem. Despite several negative consequences, some persons with SCI are resilient enough to achieve positive adjustment, greater acceptance, and better quality of life. Since resilience is influenced by several factors and can vary by context, it is beneficial to explore factors that affect the resilience of people who sustained spinal cord injury from the 2015 earthquake in Nepal. A descriptive cross-sectional study included 82 participants from the Spinal Injury Rehabilitation Center and communities in Nepal. Participants completed the Demographic and Injury-related Questionnaire, Connor-Davidson Resilience Scale, Multidimensional Scale of Perceived Social Support, Moorong Self-efficacy Scale, Intrinsic Spirituality Scale, and Patient Health Questionnaire-9. Pearson's correlation and point biserial correlation analyses were performed to examine associations between resilience and independent variables. A hierarchical regression analysis was used to identify the influence of certain factors. Findings indicated significant associations between resilience and social support (r = 0.42, p resilience and spirituality (r = - 0.12, p > 0.05). In hierarchical regression analysis, an overall regression model explained 46% of the variance in resilience. Self-efficacy (β = 0.28, p = 0.007) and depressive mood (β = - 0.24, p = 0.016) significantly determined resilience after controlling the effect of demographic variables. Among the demographic factors, being male significantly explained the variance in resilience (β = 0.31, p = 0.001). Multiple psychosocial and demographic factors were associated with resilience in people who sustained an earthquake-related SCI. Mental health professionals should demonstrate concern and consider such factors in allocating care in this group. Development

To investigate the relationship between resilience and affective state, caregiver burden and caregiving strategies among family members of people with traumatic brain or spinal cord injury. An observational prospective cross-sectional study. Inpatient and community rehabilitation services. Convenience sample of 61 family respondents aged 18 years or older at the time of the study and supporting a relative with severe traumatic brain injury (n = 30) or spinal cord injury (n= 31). Resilience Scale, Positive And Negative Affect Schedule, Caregiver Burden Scale, Functional Independence Measure, Carer's Assessment of Managing Index. Correlational analyses found a significant positive association between family resilience scores and positive affect (r(s) = 0.67), and a significant negative association with negative affect (r(s) = -0.47) and caregiver burden scores (r(s) = -0.47). No association was found between family resilience scores and their relative's severity of functional impairment. Family members with high resilience scores rated four carer strategies as significantly more helpful than family members with low resilience scores. Between-groups analyses (families supporting relative with traumatic brain injury vs. spinal cord injury) found no significant differences in ratings of the perceived helpfulness of carer strategies once Bonferroni correction for multiple tests was applied. Self-rated resilience correlated positively with positive affect, and negatively with negative affect and caregiver burden. These results are consistent with resilience theories which propose that people with high resilience are more likely to display positive adaptation when faced by significant adversity.

Boyer, Elizabeth R; Derrick, Timothy R

2015-09-01

Some frontal plane and transverse plane variables have been associated with running injury, but it is not known if they differ with foot strike style or as stride length is shortened. To identify if step width, iliotibial band strain and strain rate, positive and negative free moment, pelvic drop, hip adduction, knee internal rotation, and rearfoot eversion differ between habitual rearfoot and habitual mid-/forefoot strikers when running with both a rearfoot strike (RFS) and a mid-/forefoot strike (FFS) at 3 stride lengths. Controlled laboratory study. A total of 42 healthy runners (21 habitual rearfoot, 21 habitual mid-/forefoot) ran overground at 3.35 m/s with both a RFS and a FFS at their preferred stride lengths and 5% and 10% shorter. Variables did not differ between habitual groups. Step width was 1.5 cm narrower for FFS, widening to 0.8 cm as stride length shortened. Iliotibial band strain and strain rate did not differ between foot strikes but decreased as stride length shortened (0.3% and 1.8%/s, respectively). Pelvic drop was reduced 0.7° for FFS compared with RFS, and both pelvic drop and hip adduction decreased as stride length shortened (0.8° and 1.5°, respectively). Peak knee internal rotation was not affected by foot strike or stride length. Peak rearfoot eversion was not different between foot strikes but decreased 0.6° as stride length shortened. Peak positive free moment (normalized to body weight [BW] and height [h]) was not affected by foot strike or stride length. Peak negative free moment was -0.0038 BW·m/h greater for FFS and decreased -0.0004 BW·m/h as stride length shortened. The small decreases in most variables as stride length shortened were likely associated with the concomitant wider step width. RFS had slightly greater pelvic drop, while FFS had slightly narrower step width and greater negative free moment. Shortening one's stride length may decrease or at least not increase propensity for running injuries based on the variables

Full Text Available Abstract Introduction: studying the influence of surfing on the prevalence of injuries may contribute to prevention. Objective: to analyze the influence of time practicing sports and the occurrence of previous surgery on the profile and prevalence of injuries caused by surfing. Methods: Sixty-six Brazilian surfers (26.16 ± 0.73 years old participated in this study. Anthropometric data, physical activity level, surfing practice time and the prevalence of injuries (type of injury, anatomical region affected, and mechanism of injury were evaluated. To assess which of the studied variables exerted significant influence on the mean number of injuries, a Poisson log-linear model was adjusted through R software (p < 0.05. Results: most surfers were classified as eutrophic (73%, very active (60.6%, had an average practice time of 10.1 ± 1 years, and were not members of a surfing federation (74%. It was also observed that 90.9% of participants reported injuries caused by surfing and 44.9% affected the lower limbs. The majority of these injuries affected the integumentary system (46.6%. The main mechanism of injury was impact with the board or seabed (40.4%. Furthermore, it was found that surfing federation members presented an average of 58.4% more injuries than non-members (p = 0.007. Surfers who had undergone previous surgeries showed an average number of injuries that was 56.9% higher than other surfers (p = 0.012. In addition, it was found that for each extra year of surfing, the average number of injuries increased by 2.5% (p = 0.0118. Conclusion: the average number of injuries increased with increment in time practicing the sport, previous surgery and membership in a surfing federation.

Davies, J E; Gibson, T

In a prospective study of 185 players attached to 10 British rugby clubs, 151 injuries were recorded among 98 of them (53%) during a single season. Forwards sustained significantly more injuries than backs. The standard of rugby, players' body weights, degree of fitness, and presence of joint hypermobility did not affect the risk of injury. The leg was the most common site of injury. Head and neck injuries were significantly more common when play was static and on wet pitches. Scrummaging accounted for no neck injuries. Almost half the injuries occurred during the last quarter of games. Foul play might have caused as many as 47 (31%) of all reported injuries. Complete eradication of deliberately dangerous play would considerably reduce the high incidence of injuries in this sport.

To report the epidemiology, mechanism, anatomical location, distribution, and severity of open extensor tendon injuries in the digits, hand, and forearm as well as the frequency of associated injuries to surrounding bone and soft tissue. Retrospective chart review was conducted for patients who had operative repair of open digital extensor tendon injuries in all zones within an 11-year period. Data was grouped according to patient characteristics, zone of injury, mechanism of injury, and presence of associated injury. Statistical analysis was used to determine the presence of relevant associations. Eighty-six patients with 125 severed tendons and 105 injured digits were available for chart reviews. Patients were predominantly males (83%) with a mean age of 34.2 years and the dominant extremity was most often injured (60%). The thumb was the most commonly injured (25.7%), followed by middle finger (24.8), whereas small finger was least affected (10.5%). Sharp laceration was the most common mechanism of injury (60%), and most of these occurred at or proximal to the metacarpophalangeal joints. Most saw injuries occurred distal to the metacarpophalangeal joint. Zone V was the most commonly affected in the fingers (27%) while zone VT was the most commonly affected in the thumb (69%). Associated injuries to bone and soft tissue occurred in 46.7% of all injuries with saw and crush/avulsions being predictive of fractures and damage to the underlying joint capsule. The extensor mechanism is anatomically complex, and open injuries to the dorsum of the hand, wrist, and forearm, especially of crushing nature and those inflicted by saws, must be thoroughly evaluated. Associated injuries should be ruled out in order to customize surgical treatment and optimize outcome.

Linking firefighter injury reporting to general motion patterns may provide insight into potential injury mechanisms and the development of prevention strategies. To characterize the injuries sustained by members of a large Canadian metropolitan fire department over a 5-year span. Data were taken from injury reports filed by career firefighters between 2007 and 2011. Injuries were described by job duty, type, body part affected, and the general motion pattern employed at the time of injury (e.g. lifting). Of the 1311 injuries reported, 64% were categorized as sprains and strains (musculoskeletal disorders -MSDs), the most frequent of which affected the back (32%). Categorized by job duty, 65% of MSDs were sustained while working at the fire station or during physical training-related activities. Only 15% were attributed to fireground operations. Furthermore, the associated job duty could not differentiate the types of injuries sustained; back injuries occurred primarily while lifting, knee injuries while stepping, and shoulder injuries during pushing/pulling-related activities. Firefighter injuries are not just a fireground problem. Injury causation may be better understood by linking the injury location and type with motion patterns rather than job duties. This information could assist in developing general prevention strategies for the fire service.

There has been no comprehensive injury report of elite-level amateur boxers in competition and training. We reviewed injuries in training and competition in the Great Britain (GB) amateur boxing squad between 2005 and 2009. Longitudinal, prospective injury surveillance over 5 years of the GB boxing squad from 2005 to 2009. 66 boxers passed through the squad. The location, region affected, description, and the duration of each injury were recorded by the team doctor and team physiotherapist. We recorded whether the injury occurred during competition or training, and also whether it was a new or a recurrent injury. The injury rate during competition was calculated as the number of injuries per 1000 h. More injuries affected the hand than any other body location. This was the case overall, in training and competition individually, and for both new and recurrent injuries. More injuries occurred during training than during competition, and most injuries were new rather than recurrent. Total injury rate during competition was 828 per 1000 h and hand injury rate in competition was 302 injuries per 1000 h. Hand injury rate in competition was significantly higher than at the other locations. The incidence of concussion is comparatively low. Injury prevention should aim to protect the hands and wrists of elite amateur boxers. Published by the BMJ Publishing Group Limited.

The epidemiology of injury in skateboarding.

Science.gov (United States)

Hunter, Jamie

2012-01-01

The purpose of this report is to review the available literature to provide an epidemiological overview of skateboarding injuries, as well as to suggest possible areas for future research. A literature search was performed with the databases of PubMed, Sport Discus, Google and Google Scholar using the search terms 'skateboard', 'skateboarding', 'injury' and 'injuries', with all articles published in refereed journals in the English language being considered. An ancestry approach was also used. Articles from non-juried journals were also infrequently included to provide anecdotal information on the sport. Comparison of study results was compromised by the diversity of different study populations and variability of injury definitions across studies. The majority of injuries affect young males although conflicting arguments arise over the issues of age and experience in relation to injury severity. Most injuries are acutely suffered, and the most commonly affected body part was the wrist and forearm, with lower leg and ankle injuries also common. The incidence was relatively high but reports on severity differed. Clear conclusions could not be drawn on environmental location and risk factors. Most injuries tend to occur from a loss of balance leading to a fall, in more recent times due to a failed trick. Research on injury prevention is not conclusive although protective equipment and skatepark use are recommended. Further research using more rigorous study designs is required to gain a clearer picture of the incidence and determinants of injury, and to identify risk factors and viable injury countermeasures.

The National Center for Injury Prevention and Control, noting flaws in previous running injury research, called for more rigorous prospective designs and comprehensive analyses to define the origin of running injuries. To determine the risk factors that differentiate recreational runners who remain uninjured from those diagnosed with an overuse running injury during a 2-year observational period. Cohort study; Level of evidence, 2. Inclusion criteria were running a minimum of 5 miles per week and being injury free for at least the past 6 months. Data were collected at baseline on training, medical and injury histories, demographics, anthropometrics, strength, gait biomechanics, and psychosocial variables. Injuries occurring over the 2-year observation period were diagnosed by an orthopaedic surgeon on the basis of predetermined definitions. Of the 300 runners who entered the study, 199 (66%) sustained at least 1 injury, including 73% of women and 62% of men. Of the injured runners, 111 (56%) sustained injuries more than once. In bivariate analyses, significant ( P ≤ .05) factors at baseline that predicted injury were as follows: Short Form Health Survey-12 mental component score (lower mental health-related quality of life), Positive and Negative Affect Scale negative affect score (more negative emotions), sex (higher percentage of women were injured), and knee stiffness (greater stiffness was associated with injury); subsequently, knee stiffness was the lone significant predictor of injury (odds ratio = 1.18) in a multivariable analysis. Flexibility, quadriceps angle, arch height, rearfoot motion, strength, footwear, and previous injury were not significant risk factors for injury. The results of this study indicate the following: (1) among recreational runners, women sustain injuries at a higher rate than men; (2) greater knee stiffness, more common in runners with higher body weights (≥80 kg), significantly increases the odds of sustaining an overuse running

Powerlifting is a discipline of competitive weightlifting. To date, no investigations have focused on pain encountered during routine training. The aim of the study was to identify such pain, assign it to particular exercises and assess the data regarding injuries as well as the influence of intrinsic and extrinsic factors. Data of 245 competitive and elite powerlifters was collected by questionnaire. Information regarding current workout routines and retrospective injury data was collected. Study subjects were selected from 97 incorporated powerlifting clubs. A percentage of 43.3% of powerlifters complained of problems during routine workouts. Injury rate was calculated as 0.3 injuries per lifter per year (1 000 h of training=1 injury). There was no evidence that intrinsic or extrinsic factors affected this rate. Most commonly injured body regions were the shoulder, lower back and the knee. The use of weight belts increased the injury rate of the lumbar spine. Rate of injury to the upper extremities was significantly increased based on age >40 years (shoulder/p=0.003, elbow/p=0.003, hand+wrist/p=0.024) and female gender (hand+wrist/p=0.045). The daily workout of a large proportion of powerlifters is affected by disorders which do not require an interruption of training. The injury rate is low compared to other sports. © Georg Thieme Verlag KG Stuttgart · New York.

The participation of young in volleyball is becoming increasingly common, and this increased involvement raises concerns about the risk of installation of sports injuries. Therefore, the objectives the study were identify the characteristics of sports injuries in young volleyball players and associate anthropometric and training variables with contributing factors for injuries. A total of 522 volleyball players participating in the High School Olympic Games of the State of São Paulo (Brazil) were interviewed. A reported condition inquiry was used to gather information on injuries, such as anatomic site affected, mechanism and moment of injury, as well as personal and training data. The level of significance was set at 5%. A 19% frequency of injuries was found. Higher age, weight, height, body mass index and training duration values were associated with the occurrence of injuries. The most affected anatomic site was the ankle/foot complex (45 injuries, 36.3%). Direct contact and contactless mechanisms were the main causes of injuries (61 injuries; 49.2% and 48 injuries; 38.7%, respectively). Training was the moment in which most injuries occurred (93 injuries; 75%), independently of personal and training characteristics. Injuries affected the ankle/foot complex with a greater frequency. Direct contact and contactless mechanisms were the most frequently reported and injuries occurred mainly during training sessions. Personal and training characteristics were contributing factors for the occurrence of injuries.

Full Text Available Methimazole and propylthiouracil have been used in the management of hyperthyroidism for more than half a century. However, hepatotoxicity is one of the most deleterious side effects associated with these medications. The mechanism(s of hepatic injury induced by antithyroid agents is not fully recognized yet. Furthermore, there are no specific tools for predicting the occurrence of hepatotoxicity induced by these drugs. The purpose of this article is to give an overview on possible susceptibility factors in liver injury induced by antithyroid agents. Age, gender, metabolism characteristics, alcohol consumption, underlying diseases, immunologic mechanisms, and drug interactions are involved in enhancing antithyroid drugs-induced hepatic damage. An outline on the clinically used treatments for antithyroid drugs-induced hepatotoxicity and the potential therapeutic strategies found to be effective against this complication are also discussed.

2016-06-01

The present study evaluated whether the MRI parameters of hamstring injuries in male professional football players correlate with time to return to play (RTP). 46 elite European football teams were followed prospectively for hamstring injuries between 2007 and 2014. Club medical staff recorded individual player exposure and time-loss after hamstring injury. MRI parameters were evaluated by two independent radiologists and correlated with the RTP data. A total of 255 grade 1 and 2 injuries were evaluated in this study. RTP was longer for grade 2 than grade 1 injuries (24±13, 95% CI 21 to 26 days vs 18±15, 95% CI 16 to 20 days; mean difference: 6, 95% CI 2 to 9 days, p=0.004, d=0.39). 84% of injuries affected the biceps femoris (BF) muscle, whereas 12% and 4% affected the semimembranosus (SM) and semitendinosus (ST), respectively. No difference in lay-off time was found for injuries to the three different muscles (BF 20±15 days, SM 18±11 days, ST 23±14 days; p=0.83). The recurrence rate was higher for BF injuries than for SM and ST injuries combined (18% vs 2%, p=0.009). The size of the oedema weakly correlated with time to RTP (r(2)=6-12%). No correlation was found between location of injury and time to RTP. The majority of the intramuscular injuries affected the MT junction (56% in grade 1 and 2 injuries), but no difference in lay-off time was found between the different types of injuries. The radiological grade and size of the oedema correlate with time to RTP for both, grade 1 and 2 injuries. No correlations were found between time to RTP and the location and type of injury.

To develop an item response theory (IRT)-calibrated spinal cord injury (SCI)-specific Positive Affect and Well-being (PAWB) item bank with flexible options for administration. Qualitative feedback from patient and provider focus groups was used to expand on the Neurological Disorders and Quality of Life (Neuro-QOL) positive affect & well-being item bank for use in SCI. New items were created and revised based on expert review and patient feedback and were then field tested. Analyses included confirmatory factor analysis, graded response IRT modeling and evaluation of differential item functioning (DIF). We tested a 32-item pool at several rehabilitation centers across the United States, including the University of Michigan, Kessler Foundation, Rehabilitation Institute of Chicago, the University of Washington, Craig Hospital and the James J. Peters/Bronx Department of Veterans Affairs hospital. A total of 717 individuals with SCI answered the PAWB questions. A unidimensional model was observed (Confirmatory Fit Index=0.947; Root Mean Square Error of Approximation=0.094) and measurement precision was good (reliability in theta of -2.9 to 1.2 is roughly equivalent to classical reliability of 0.95 or above). Twelve items were flagged for DIF, however, after examination of effect sizes, the DIF was determined to be negligible and would have little practical impact on score estimates. The final calibrated item bank resulted in 28 retained items This study indicates that the Spinal Cord Injury--Quality of Life PAWB bank represents a psychometrically robust measurement tool. Short form items are also suggested and a computer adaptive test is available.

Overdose of acetaminophen (APAP) results in acute liver failure. We have investigated the role of a posttranslational modification of proteins called O-GlcNAcylation, where the O-GlcNAc transferase (OGT) adds and O-GlcNAcase (OGA) removes a single β-D-N-acetylglucosamine (O-GlcNAc) moiety, in the pathogenesis of APAP-induced liver injury. Hepatocyte-specific OGT knockout mice (OGT KO), which have reduced O-GlcNAcylation, and wild-type (WT) controls were treated with 300 mg/kg APAP and the development of injury was studied over a time course from 0 to 24 h. OGT KO mice developed significantly lower liver injury as compared with WT mice. Hepatic CYP2E1 activity and glutathione (GSH) depletion following APAP treatment were not different between WT and OGT KO mice. However, replenishment of GSH and induction of GSH biosynthesis genes were significantly faster in the OGT KO mice. Next, male C57BL/6 J mice were treated Thiamet-G (TMG), a specific inhibitor of OGA to induce O-GlcNAcylation, 1.5 h after APAP administration and the development of liver injury was studied over a time course of 0-24 h. TMG-treated mice exhibited significantly higher APAP-induced liver injury. Treatment with TMG did not affect hepatic CYP2E1 levels, GSH depletion, APAP-protein adducts, and APAP-induced mitochondrial damage. However, GSH replenishment and GSH biosynthesis genes were lower in TMG-treated mice after APAP overdose. Taken together, these data indicate that induction in cellular O-GlcNAcylation exacerbates APAP-induced liver injury via dysregulation of hepatic GSH replenishment response.

Caine, Dennis; Goodwin, Brett J; Caine, Caroline G; Bergeron, Glen

2015-12-01

The objective of this study was to provide an epidemiological review of the literature concerning ballet injuries affecting pre-professional ballet dancers. The literature search was limited to published peer-reviewed reports and involved an extensive examination of Scopus, SPORTDiscus, and CINAHL. The following search terms were used in various combinations: ballet, injury, epidemiology, risk factor, pre-professional, and intervention. Additional citations were located using the ancestry approach. Unlike some other athletic activities that have been the focus of recent intervention research, there is a paucity of intervention and translational research in pre-professional ballet, and sample sizes have often been small and have not accounted for the multivariate nature of ballet injury. Exposure-based injury rates in this population appear similar to those reported for professional ballet dancers and female gymnasts. A preponderance of injuries affect the lower extremity of these dancers, with sprains and strains being the most frequent type of injury reported. The majority of injuries appear to be overuse in nature. Injury risk factors have been tested in multiple studies and indicate a variety of potential injury predictors that may provide useful guidance for future research.

Behaviour, the key factor for sports injury prevention.

Science.gov (United States)

Verhagen, Evert A L M; van Stralen, Maartje M; van Mechelen, Willem

2010-11-01

Safety in sports and physical activity is an important prerequisite for continuing participation in sports, as well as for maintenance of a healthy physically active lifestyle. For this reason, prevention, reduction and control of sports injuries are important goals for society as a whole. Recent advances in sports medicine discuss the need for research on real-life injury prevention. Such views call for a more behavioural approach when it comes to actual sports injury prevention. Nevertheless, the role of behaviour in sports injury prevention remains under-researched. In order to push the field of sports injury prevention forward, this article provides an overview of the relationship between behaviour and sports injury risk. Different types of behaviour relate to injury risk factors and injury mechanisms. Behaviour that influences risk factors and injury mechanisms is not confined only to the athlete. Various types of behaviour by, for example, the coach, referee, physical therapist or sports associations, also influence risk factors and injury mechanisms. In addition, multiple behaviours often act together. Some types of behaviour may directly affect injury risk and are by definition a risk factor. Other behaviours may only affect risk factors and injury mechanisms, and influence injury risk indirectly. Recent ideas on injury prevention that call for studies on real-life injury prevention still rely heavily on preventive measures that are established through efficacy research. A serious limitation in such an approach is that one expects that proven preventive measures will be adopted if the determinants and influences of sports safety behaviours are understood. Therefore, if one truly wants to prevent sports injuries in a real-life situation, a broader research focus is needed. In trying to do so, we need to look at lessons learned from other fields of injury prevention research.

The presence of nonthoracic distracting injuries does not affect the initial clinical examination of the cervical spine in evaluable blunt trauma patients: a prospective observational study.

A distracting injury mandates cervical spine (c-spine) imaging in the evaluable blunt trauma patient who demonstrates no pain or tenderness over the c-spine. The purpose of this study was to examine which distracting injuries can negatively affect the sensitivity of the standard clinical examination of the c-spine. This is a prospective observational study conducted at a Level I Trauma Center from January 1, 2008, to December 31, 2009. After institutional review board approval, all evaluable (Glasgow Coma Scale score ≥13) blunt trauma patients older than 16 years sustaining a c-spine injury were enrolled. A distracting injury was defined as any immediately evident bony or soft tissue injury or a complaint of non-c-spine pain whether or not an actual injury was subsequently diagnosed. Information regarding the initial clinical examination and the presence of a distracting injury was collected from the senior resident or attending trauma surgeon involved in the initial management. During the study period, 101 evaluable patients sustained a c-spine injury. Distracting injuries were present in 88 patients (87.1%). The most common was rib fracture (21.6%), followed by lower extremity fracture (20.5%) and upper extremity fracture (12.5%). Only four (4.0%) patients had no pain or tenderness on the initial examination of the c-spine. All four patients had bruising and tenderness to the upper anterior chest. None of these four patients developed neurologic sequelae or required a surgical stabilization or immobilization. C-spine imaging may not be required in the evaluable blunt trauma patient despite distracting injuries in any body regions that do not involve the upper chest. Further definition of distracting injuries is mandated to avoid unnecessary utilization of resources and to reduce the imaging burden associated with the evaluation of the c-spine.

Documentation and evaluation of dental injuries in forensic medicine are rather problematic. It needs a professional work up why dental injuries are out of focus, and how the diagnosis, pattern and treatment are influenced by novel approaches of dentistry. The aims of the authors were to characterize dental injuries, to compare their own findings to literature data concerning the type and characteristics of injuries, and propose a diagnostic workflow. Expert's reports between 2009 and 2013 at the Department of Forensic Medicine, University of Szeged were reviewed. Review of about 7000 reports revealed only 20 cases with dental injury, which is in contrast with literature data indicating a significantly higher frequency of dental injuries. Although the number of "dental cases" was low, there were several additional cases where the trauma probably affected the teeth but the injury was not documented. In future more attention is needed in forensic evaluation of the mechanism, therapeutic strategy and prognosis of dental injuries.

Pre-injury beta blocker use does not affect the hyperdynamic response in older trauma patients

Directory of Open Access Journals (Sweden)

David C Evans

2014-01-01

Full Text Available Purpose: Trauma dogma dictates that the physiologic response to injury is blunted by beta-blockers and other cardiac medications. We sought to determine how the pre-injury cardiac medication profile influences admission physiology and post-injury outcomes. Materials and Methods: Trauma patients older than 45 evaluated at our center were retrospectively studied. Pre-injury medication profiles were evaluated for angiotensin-converting enzyme inhibitors / angiotensin receptor blockers (ACE-I/ARB, beta-blockers, calcium channel blockers, amiodarone, or a combination of the above mentioned agents. Multivariable logistic regression or linear regression analyses were used to identify relationships between pre-injury medications, vital signs on presentation, post-injury complications, length of hospital stay, and mortality. Results: Records of 645 patients were reviewed (mean age 62.9 years, Injury Severity Score >10, 23%. Our analysis demonstrated no effect on systolic and diastolic blood pressures from beta-blocker, ACE-I/ARB, calcium channel blocker, and amiodarone use. The triple therapy (combined beta-blocker, calcium channel blocker, and ACE-I/ARB patient group had significantly lower heart rate than the no cardiac medication group. No other groups were statistically different for heart rate, systolic, and diastolic blood pressure. Conclusions: Pre-injury use of cardiac medication lowered heart rate in the triple-agent group (beta-blocker, calcium channel blocker, and ACEi/ARB when compared the no cardiac medication group. While most combinations of cardiac medications do not blunt the hyperdynamic response in trauma cases, patients on combined beta-blocker, calcium channel blocker, and ACE-I/ARB therapy had higher mortality and more in-hospital complications despite only mild attenuation of the hyperdynamic response.

To honor Tom Waters's work on emerging occupational health issues, we review the literature on physical along with chemical exposures and their impact on functional outcomes. Many occupations present the opportunity for exposure to multiple hazardous exposures, including both physical and chemical factors. However, little is known about how these different factors affect functional ability and injury. The goal of this review is to examine the relationships between these exposures, impairment of the neuromuscular and musculoskeletal systems, functional outcomes, and health problems with a focus on acute injury. Literature was identified using online databases, including PubMed, Ovid Medline, and Google Scholar. References from included articles were searched for additional relevant articles. This review documented the limited existing literature that discussed cognitive impairment and functional disorders via neurotoxicity for physical exposures (heat and repetitive loading) and chemical exposures (pesticides, volatile organic compounds [VOCs], and heavy metals). This review supports that workers are exposed to physical and chemical exposures that are associated with negative health effects, including functional impairment and injury. Innovation in exposure assessment with respect to quantifying the joint exposure to these different exposures is especially needed for developing risk assessment models and, ultimately, preventive measures. Along with physical exposures, chemical exposures need to be considered, alone and in combination, in assessing functional ability and occupationally related injuries. © 2016, Human Factors and Ergonomics Society.

Work related back injuries among hospital personnel account for high volume, high cost workers' compensation claims. These injuries can be life altering experiences, affecting both the personal and professional lives of injured workers. Lifting must be viewed as a skill involving specialized training and mandated use of mechanical equipment, rather than as a random task performed by numerous health care providers. The use of a lift team specially trained in body mechanics, lifting techniques, and the use of mandated mechanical equipment can significantly affect injury data, financial outcomes, and employee satisfaction. The benefits of a lift team extend beyond the effect on injury and financial outcomes--they can be used for recruitment and retention strategies, and team members serve as mentors to others by demonstrating safe lifting techniques. Ultimately, a lift team helps protect a valuable resource--the health care worker.

The aim of this study is to assess the ability of EEG-based indices in providing relevant information about cognitive engagement level during the execution of a clinical sustained attention (SA) test in healthy volunteers and DAI (diffused axonal injury)-affected patients. We computed three continuous power-based engagement indices (P β /P α , 1/P α , and P β / (P α + P θ )) from EEG recordings in a control group (n = 7) and seven DAI-affected patients executing a 10-min Conners' "not-X" continuous performance test (CPT). A correlation analysis was performed in order to investigate the existence of relations between the EEG metrics and behavioral parameters in both the populations. P β /P α and 1/P α indices were found to be correlated with reaction times in both groups while P β / (P α + P θ ) and P β /P α also correlated with the errors rate for DAI patients. In line with previous studies, time course fluctuations revealed a first strong decrease of attention after 2 min from the beginning of the test and a final fading at the end. Our results provide evidence that EEG-derived indices extraction and evaluation during SA tasks are helpful in the assessment of attention level in healthy subjects and DAI patients, offering motivations for including EEG monitoring in cognitive rehabilitation practice. Graphical abstract Three EEG-derived indices were computed from four electrodes montages in a population of seven healthy volunteers and a group of seven DAI-affected patients. Results show a significant correlation between the time course of the indices and behavioral parameters, thus demonstrating their usefulness in monitoring mental engagement level during a sustained attention task.

The Occupational Safety and Health Administration (OSHA) and the Bureau of Labor Statistics (BLS) provide the Survey of Occupational Illness and Injury (SOII) statistics from 1992 to 2006, which is often used to measure the rate of injuries and illness in industry. The present system of gathering and classifying this data was implemented in 1992 with minor changes in 2002. It is hoped that using these statistics to measure safety progress and determine patterns of injury will guide further improvements in chemical safety. Recognizing such factors as what chemicals most frequently cause injury can help to focus safety efforts regarding that chemical. Factors such as what part of the body is most commonly affected by particular chemicals can lead to improved personnel protection practices. This paper provides a detailed analysis of injuries due to chemicals using OSHA's SOII data, which offers valuable insight into measures that should be taken to reduce injuries due to chemicals.

Pietrosimone, Brian G; McLeod, Michelle M; Lepley, Adam S

2012-01-01

Neuromuscular alterations are common following lower extremity joint injury and often lead to decreased function and disability. These neuromuscular alterations manifest in inhibition or abnormal facilitation of the uninjured musculature surrounding an injured joint. Unfortunately, these neural alterations are poorly understood, which may affect clinical recognition and treatment of these injuries. Understanding how these neural alterations affect physical function may be important for proper clinical management of lower extremity joint injuries. Pertinent articles focusing on neuromuscular consequences and treatment of knee and ankle injuries were collected from peer-reviewed sources available on the Web of Science and Medline databases from 1975 through 2010. A theoretical model to illustrate potential relationships between neural alterations and clinical impairments was constructed from the current literature. Lower extremity joint injury affects upstream cortical and spinal reflexive excitability pathways as well as downstream muscle function and overall physical performance. Treatment targeting the central nervous system provides an alternate means of treating joint injury that may be effective for patients with neuromuscular alterations. Disability is common following joint injury. There is mounting evidence that alterations in the central nervous system may relate to clinical changes in biomechanics that may predispose patients to further injury, and novel clinical interventions that target neural alterations may improve therapeutic outcomes.

Dirt bike riding is becoming a more popular recreational activity among children. Injuries associated with this recreational activity did not gain attention in the medical literature. The purpose of this study is to assess orthopedic injuries associated with dirt bike riding. We retrospectively studied injuries occurring in children less than 18 years old, while riding dirt bikes, that required admission to the trauma department in our level one trauma center during the period 2000-2010. There were 24 admissions (23 patients). The mean age was 13. Fourteen patients had brain injuries. Six patients had abdominal injuries. One patient died shortly after arriving to the emergency department. Fourteen patients had face and neck injuries. The average injury severity score was 8.5. Thirteen patients' admissions (54 %) had orthopedic fractures. Five of 13 patients (38 %) suffered more than one fracture. Eight patients needed orthopedic intervention (seven of these were in operating room under general anesthesia and one in the emergency department under conscious sedation). Femur fracture was the most common cause for performing surgery in this group of patients. Riding dirt bikes is not a safe recreational activity. Orthopedic injuries constitute a major component of the injuries affecting children riding dirt bikes. Orthopedic surgeons (being responsible for treating most of these children) have the obligation to warn the community against the possible dangers facing children who ride dirt bikes.

A volunteer sample of 50 competitive field hockey players completed the Coopersmith Self-esteem Inventory at pre- and postseason and prospectively collected injury data over a 20-wk. season. Multiple regression analysis showed no relationship between scores on Self-esteem and the number of injuries, the participation time affected due to injury, and sex of players. Further multiple regression analysis showed that frequency of the more severe injuries significantly predicted scores on Self-esteem. This finding can be interpreted as evidence of the relationship between low self-esteem and injury in sport.

Burn-injury affects gut-associated lymphoid tissues derived CD4+ T cells.

Fazal, Nadeem; Shelip, Alla; Alzahrani, Alhusain J

2013-01-01

After scald burn-injury, the intestinal immune system responds to maintain immune balance. In this regard CD4+T cells in Gut-Associated Lymphoid Tissues (GALT), like mesenteric lymph nodes (MLN) and Peyer's patches (PP) respond to avoid immune suppression following major injury such as burn. Therefore, we hypothesized that the gut CD4+T cells become dysfunctional and turn the immune homeostasis towards depression of CD4+ T cell-mediated adaptive immune responses. In the current study we show down regulation of mucosal CD4+ T cell proliferation, IL-2 production and cell surface marker expression of mucosal CD4+ T cells moving towards suppressive-type. Acute burn-injury lead to up-regulation of regulatory marker (CD25+), down regulation of adhesion (CD62L, CD11a) and homing receptor (CD49d) expression, and up-regulation of negative co-stimulatory (CTLA-4) molecule. Moreover, CD4+CD25+ T cells of intestinal origin showed resistance to spontaneous as well as induced apoptosis that may contribute to suppression of effector CD4+ T cells. Furthermore, gut CD4+CD25+ T cells obtained from burn-injured animals were able to down-regulate naïve CD4+ T cell proliferation following adoptive transfer of burn-injured CD4+CD25+ T cells into sham control animals, without any significant effect on cell surface activation markers. Together, these data demonstrate that the intestinal CD4+ T cells evolve a strategy to promote suppressive CD4+ T cell effector responses, as evidenced by enhanced CD4+CD25+ T cells, up-regulated CTLA-4 expression, reduced IL-2 production, tendency towards diminished apoptosis of suppressive CD4+ T cells, and thus lose their natural ability to regulate immune homeostasis following acute burn-injury and prevent immune paralysis.

In this study, we aimed to investigate the effects of an unstable group structure, caused by weekly regroupings, on behaviour and frequency of injuries in young horses. Forty...... after each regrouping (2 × 20 min/group/day). Injuries were scored by the end of the experimental period. The level of aggression shown by horses in Unstable groups immediately after regrouping was not affected by week (F5,35 = 0.42, P = 0.83), indicating that horses neither habituated, nor sensitized...... injuries were registered and there was no treatment effect (U = 184; P = 0.11). We conclude that the behaviour of young horses is affected by group management, and that horses appear not to adapt to weekly regroupings....

Though public transport vehicles are rarely involved in mass casualty accidents, when they are, the number of injuries and fatalities is usually high due to the high passenger capacity. Of the few studies that have been conducted on bus safety, the majority focused on vehicle safety features, road environmental factors, as well as driver characteristics. Nevertheless, few studies have attempted to investigate the underlying risk factors related to bus occupants. This article presents an investigation aimed at identifying the risk factors affecting injury severity of bus passengers with different movements. Three different passenger movement types including standing, seated, and boarding/alighting were analyzed individually using classification and regression tree (CART) method based on publicly available accident database of Great Britain. According to the results of exploratory analyses, passenger age and vehicle maneuver are associated with passenger injury severity in all 3 types of accidents. Moreover, the variable "skidding and overturning" is associated with injury severity of seated passengers and driver age is correlated with injury severity of standing and boarding/alighting passengers. The CART method shows its ability to identify and easily explain the complicated patterns affecting passenger injury severity. Several countermeasures to reduce bus passenger injury severity are recommended.

Over 90% of injury deaths occur in low-and middle-income countries. However, the epidemiological profile of injuries in Pacific Islands has received little attention. We used a population-based-trauma registry to investigate the characteristics of all injuries in Viti Levu, Fiji. The Fiji Injury Surveillance in Hospitals (FISH) database prospectively collected data on all injury-related deaths and primary admissions to hospital (≥ 12 hours stay) in Viti Levu during 12 months commencing October 2005. The 2167 injury-related deaths and hospitalisations corresponded to an annual incidence rate of 333 per 100,000, with males accounting for twice as many cases as females. Almost 80% of injuries involved people aged less than 45 years, and 74% were deemed unintentional. There were 244 fatalities (71% died before admission) and 1994 hospitalisations corresponding to crude annual rates of 37.5 per 100,000 and 306 per 100,000 respectively. The leading cause of fatal injury was road traffic injury (29%) and the equivalent for injury admissions was falls (30%). The commonest type of injury resulting in death and admission to hospital was asphyxia and fractures respectively. Alcohol use was documented as a contributing factor in 13% of deaths and 12% of admissions. In general, indigenous Fijians had higher rates of injury admission, especially for interpersonal violence, while those of Indian ethnicity had higher rates of fatality, especially from suicide. Injury is an important public health problem that disproportionately affects young males in Fiji, with a high proportion of deaths prior to hospital presentation. This study highlights key areas requiring priority attention to reduce the burden of potentially life-threatening injuries in Fiji.

Nippert, Angela H; Smith, Aynsley M

2008-05-01

Injury rates are high among children and adolescent athletes. Psychosocial stressors, such as personality, history of stressors, and life event stress can influence injury occurrence. After injury, those same factors plus athletic identity, self-esteem, and significant others-such as parents, coaches, and teammates-can affect injury response, recovery and subsequent sport performance. Goal setting, positive self-talk, attribution theory, and relaxation or mental imagery are psychologic interventions that can help injured athletes cope with psychosocial stressors. Medical professionals should be aware of the potential influence that psychosocial stressors and psychologic interventions can have on injury occurrence, injury recovery, and sport performance.

We present a rare case of orbitocranial penetrating injury by a watercolor brush in a 3-year-old child. Injuries of this localization can affect important orbital structures (eyeball, blood vessels, nerves, muscles) and cause severe intracranial damages. In some cases, diagnosis of these injuries in children may be difficult due to the lack of marked clinical manifestations. The presented clinical case illustrates the approaches for choosing methods for diagnosis of injury in childhood and subsequent treatment options.

Full Text Available Abstract The purpose of this study was to investigate the injuries prevalence in men elite artistic gymnasts. Twenty Brazilian senior gymnasts, aged 23.1 ± 6.5 years, 13.9 ± 5.0 years of practice and 36.5 ± 4.7 hours per week training, participated in this study. The athletes answered a morbidity questionnaire, formulated according to studies from the literature, for information on the injuries’ characteristics and circumstances. Information about the injury circumstances (gymnastic apparatus, overload training and physical exercises, the anatomic site injured, the affect biological tissue and the return to training after injury treatment were evaluated. Data were analyzed by descriptive statistics, absolute and relative frequencies. The training overload, and floor, pommel horse and vault were the events that presented higher injuries frequency. In relation to anatomic site, ankle, hands/fingers and shoulder were the most cited regions. The ligament, bone and articular capsule were the most affected biological tissues. In relation to gymnasts’ return to their sports activities, 56% of them reported a better condition at return, 33% reported to have returned at the same fitness level and 10% indicated that they were in a worse condition when they returned to the sports activities. The men’s artistic gymnastics injuries are related to the mechanical demands of this sport. The analysis of risk factors helps in understanding the injuries mechanisms in gymnastics, and provides relevant information that can assist in effective prevention strategies.

A population of Pax7-expressing muscle progenitor cells show differential responses to muscle injury dependent on developmental stage and injury extent

Directory of Open Access Journals (Sweden)

Full Text Available Muscle regeneration in vertebrates occurs by the activation of quiescent progenitor cells that express pax7 and replace and repair damaged fibers. We have developed a mechanical injury paradigm in zebrafish to determine whether developmental stage and injury size affect the regeneration dynamics of damaged muscle. We found that both small, focal injuries and large injuries affecting the entire myotome lead to the expression of myf5 and myogenin. Their expression was prolonged in older larvae, indicating a slower process of regeneration. We characterized the endogenous behavior of a population of muscle-resident Pax7-expressing cells using a pax7a:eGFP transgenic line and found that GFP+ cell migration in the myotome dramatically declined between 5 and 7 days post fertilization (dpf. Following a small injury, we observed that GFP+ cells responded by extending processes, before migrating to the injured fibers. Furthermore, these cells responded more rapidly to injury in 4dpf larvae compared to 7dpf. Interestingly, we did not see GFP+ fibers after repair of small injuries, indicating that pax7a-expressing cells did not contribute to fiber formation in this injury context. On the contrary, numerous GFP+ fibers could be observed after a large single myotome injury. Both injury models were accompanied by an increased number of proliferating GFP+ cells, which was more pronounced in larvae injured at 4dpf than 7dpf, This indicates intriguing developmental differences, even at these relatively early ages. Our data also suggests an interesting disparity in the role that pax7a-expressing muscle progenitor cells play during muscle regeneration, which may reflect the extent of muscle damage.

Differences in Factors Affecting Various Crash Types with High Numbers of Fatalities and Injuries in China

2016-01-01

Objectives Road traffic crashes that involve very high numbers of fatalities and injuries arouse public concern wherever they occur. In China, there are two categories of such crashes: a crash that results in 10–30 fatalities, 50–100 serious injuries or a total cost of 50–100 million RMB ($US8-16m) is a “serious road traffic crash” (SRTC), while a crash that is even more severe or costly is a “particularly serious road traffic crash” (PSRTC). The aim of this study is to identify the main factors affecting different types of these crashes (single-vehicle, head-on, rear-end and side impact) with the ultimate goal of informing prevention activities and policies. Methods Detailed descriptions of the SRTCs and PSRTCs that occurred from 2007 to 2014 were collected from the database “In-depth Investigation and Analysis System for Major Road Traffic Crashes” (IIASMRTC), which is maintained by the Traffic Management Research Institute of the Ministry of Public Security of China (TMRI). 18 main risk factors, which were categorized into four areas (participant, vehicle, road and environment-related) were chosen as potential independent variables for the multinomial logistic regression analysis. Comparisons were made among the single-vehicle, head-on, rear-end and side impact crashes in terms of factors affecting crash occurrence. Findings Five risk factors were significant for the six multinomial logistic regression models, which were location, vertical alignment, roadside safety rating, driver distraction and overloading of cargo. It was indicated that intersections were more likely to have side impact SRTCs and PSRTCs, especially with poor visibility at night. Overloaded freight vehicles were more likely to be involved in a rear-end crash than other freight vehicles. Driver distraction is an important risk factor for head-on crashes, while vertical alignment and roadside safety rating are positively associated with single-vehicle crashes. Conclusion Based

2015-08-01

The purpose of this study was to examine beach volleyball players' experience regarding shoulder injury and how it affects their return to play. To achieve the research aims a qualitative design with semi-structured interviews had been conducted, five elite beach volleyball players, four men and one woman aged 27-42 participated in the study. All participants had suffered a severe shoulder injury, with absence from training and competing for at least 28 days. The findings of this study indicate that it is the individual's inner motivation, together with a clear goal and support from the community, family, teammate and coach that are the most important factors when going through rehabilitation and getting back to playing beach volleyball after a shoulder injury. All participants had been affected by their injury in some way; some of the participants had been affected in a positive way since they had become mentally stronger and had developed better volleyball technique after rehabilitation. The conclusions of this study indicate that there are three distinct factors that increase the chances of getting back to playing beach volleyball after shoulder injury; it is the players' self motivation, together with a clear goal and support from the community.

2010-01-01

Vibrating machines are used in a variety of occupations. Exposure to hand-arm vibration can cause vascular, neurological, and muscular symptoms in the hands and arms. This qualitative study provides a deeper understanding of the consequences of vibration injuries in women. In depth interviews were conducted with eight women with vibration injuries. The women were metal and wood product assemblers and dental personnel. The transcribed interviews were analyzed in accordance with the grounded theory method. The core category in the findings was "another life". This was constructed by the categories "consequences for everyday activities", "work performance", "household duties", "leisure", and "self perception" and shows that the injury had affected most parts of the women's lives and decreased their quality of life. The importance of well-functioning hands in all activities was highlighted. Reduced hand function due to numbness, muscle weakness, and pain caused restricted abilities to perform activities at work, at home, and during leisure time. The women described impact on their self-perception, as the injury had affected them in their roles as a worker, mother, and woman. The findings indicate that a vibration injury is a multidimensional problem that can affect every aspect of an individual's life. Health care providers should be aware of these complex consequences.

Strain and rate-dependent neuronal injury in a 3D in vitro compression model of traumatic brain injury

Bar-Kochba, Eyal; Scimone, Mark T.; Estrada, Jonathan B.; Franck, Christian

2016-01-01

In the United States over 1.7 million cases of traumatic brain injury are reported yearly, but predictive correlation of cellular injury to impact tissue strain is still lacking, particularly for neuronal injury resulting from compression. Given the prevalence of compressive deformations in most blunt head trauma, this information is critically important for the development of future mitigation and diagnosis strategies. Using a 3D in vitro neuronal compression model, we investigated the role of impact strain and strain rate on neuronal lifetime, viability, and pathomorphology. We find that strain magnitude and rate have profound, yet distinctively different effects on the injury pathology. While strain magnitude affects the time of neuronal death, strain rate influences the pathomorphology and extent of population injury. Cellular injury is not initiated through localized deformation of the cytoskeleton but rather driven by excess strain on the entire cell. Furthermore we find that, mechanoporation, one of the key pathological trigger mechanisms in stretch and shear neuronal injuries, was not observed under compression. PMID:27480807

2014-06-01

The sales of recreational trampolines have increased during the past few years. Severe injuries are associated in part with trampoline sport in the domestic setting. Therefore, this study was conducted to confirm the hypothesis of an increase in trampoline-related injuries in conjunction with the increasing sales of recreational trampolines and to find out what kind of injuries are most frequent in this context. Between 01/1999 and 09/2013 all trampoline-related injuries of children (0-16 years of age) were assessed retrospectively. Only those cases were evaluated which described with certainty a trampoline-associated trauma. The fractures were considered separately and assigned to specific localisations. Additionally, accidents at home were differentiated from institutional accidents. Within the past 13 years and 9 months trampoline-related injuries were seen in 195 infants. Fractures were present in 83 cases (42 %). The average age was 10 ± 3.4 years (range: 2-16 years). Within first half of the observed time period (7½ years; 01/1999 to 06/2006) 73 cases were detected with a significantly increasing number of injuries up to 122 cases between 07/2006 and 09/2013 (7 years, 3 months), which corresponds to an increase of 67 % (p = 0,028). The vast majority of these injuries happened in the domestic setting (90 %, n = 175), whereas only 10 % (n = 20) of the traumas occurred in public institutions. In 102 children (52 %) the lower extremity was affected and in 51 patients (26 %) the upper extremity was involved (head/spine/pelvis: n = 42, 22 %). The upper extremity was primarily affected by fractures and dislocations (n = 38, 76 %). At the upper extremity there were more injuries requiring surgery in contrast to the lower extremity (n = 11) or cervical spine (n = 1). The underlying data show a significant increase of trampoline-related injuries within the past years. The upper extremity is the second most affected

Full Text Available Abstract Background Over 90% of injury deaths occur in low-and middle-income countries. However, the epidemiological profile of injuries in Pacific Islands has received little attention. We used a population-based-trauma registry to investigate the characteristics of all injuries in Viti Levu, Fiji. Method The Fiji Injury Surveillance in Hospitals (FISH database prospectively collected data on all injury-related deaths and primary admissions to hospital (≥12 hours stay in Viti Levu during 12 months commencing October 2005. Results The 2167 injury-related deaths and hospitalisations corresponded to an annual incidence rate of 333 per 100,000, with males accounting for twice as many cases as females. Almost 80% of injuries involved people aged less than 45 years, and 74% were deemed unintentional. There were 244 fatalities (71% died before admission and 1994 hospitalisations corresponding to crude annual rates of 37.5 per 100,000 and 306 per 100,000 respectively. The leading cause of fatal injury was road traffic injury (29% and the equivalent for injury admissions was falls (30%. The commonest type of injury resulting in death and admission to hospital was asphyxia and fractures respectively. Alcohol use was documented as a contributing factor in 13% of deaths and 12% of admissions. In general, indigenous Fijians had higher rates of injury admission, especially for interpersonal violence, while those of Indian ethnicity had higher rates of fatality, especially from suicide. Conclusions Injury is an important public health problem that disproportionately affects young males in Fiji, with a high proportion of deaths prior to hospital presentation. This study highlights key areas requiring priority attention to reduce the burden of potentially life-threatening injuries in Fiji.

Otorhinolaryngology (ORL) is considered a specialty associated with few serious patient injuries. Research data that support this belief are, however, scarce. We analyzed claims associated with ORL to determine the number of Finnish cases and the possible common denominators. Register study of ORL cases in the Patient Insurance Centre (PIC), the Regional State Administrative Agencies (RSAA), and the National Supervisory Authority for Welfare and Care (Valvira) during the years 2004 to 2008. These three agencies are the main actors in the field of patient injury in Finland. We analyzed compensated ORL patient injury cases from the PIC and cases associated with the ORL specialty for Valvira and RSAA from 2004 to 2008 and surveyed patient treatment files, statements from specialists, and compensation decisions. Injuries were usually associated with operations; three patients who experienced injuries during these procedures died. Common ORL operations such as tonsillectomy, septoplasty, and paranasal sinus surgery were most often associated with compensated injuries. Serious injuries were few, with a total of 110 out of 422 (26.1%) claims compensated by the PIC. Of the 110 compensated cases, 30 (27.3%) were related to tumor surgery. The most usual compensated case had iatrogenic nerve injury affecting the facial or trigeminal nerves. Of the compensated cases, 79 (71.8%) were treated by specialists, 15 (13.6%) by residents, and the rest by other medical professionals. Patient injuries in ORL are seldom severe and are strongly associated with surgery. A typical compensated injury was one that occurred in a central hospital during working hours. N/A.

PURPOSE: Physical activity related injuries in children constitute a costly public health matter. The influence of motor performance on injury risk is unclear. The purpose was to examine if motor performance was a risk factor of traumatic and overuse lower extremity injuries in a normal population...... motor performance (core stability, vertical jump, shuttle run) was positively associated with traumatic and overuse injuries, and negatively (single leg hop) associated with traumatic injuries, indicating different influence on injury risk. Previous injury was a confounder affecting the effect size...... and the significance. More studies are needed to consolidate the findings, to clarify the influence of different performance tests on different types of injuries and to examine the influence of behaviour in relation to injury risk....

Moral injury represents an emerging clinical construct recognized as a source of morbidity in current and former military personnel. Finding effective ways to support those affected by moral injury remains a challenge for both biomedical and complementary and alternative medicine. This paper introduces the concept of moral injury and suggests two complementary and alternative medicine, pastoral care and mindfulness, which may prove useful in supporting military personnel thought to be dealing with moral injury. Research strategies for developing an evidence-base for applying these, and other, complementary and alternative medicine modalities to moral injury are discussed. Published by Elsevier Ltd.

Self-inflicted injury in adolescence indicates significant emotional and psychological suffering. Although data on the etiology of self-injury are limited, current theories suggest that the emotional lability observed among self-injuring adolescents results from complex interactions between individual biological vulnerabilities and environmental risk. For example, deficiencies in serotonergic functioning, in conjunction with certain family interaction patterns, may contribute to the development of emotional lability and risk for self-injury. The authors explored the relation between peripheral serotonin levels and mother–child interaction patterns among typical (n = 21) and self-injuring (n = 20) adolescents. Findings revealed higher levels of negative affect and lower levels of both positive affect and cohesiveness among families of self-injuring participants. Peripheral serotonin was also correlated with the expression of positive affect within dyads. Furthermore, adolescents’ serotonin levels interacted with negativity and conflict within dyads to explain 64% of the variance in self-injury. These findings underscore the importance of considering both biological and environmental risk factors in understanding and treating self-injuring adolescents. PMID:18229978

Identification of high-risk sports, including their most common and severe injuries and illnesses, will facilitate the identification of sports and athletes at risk at an early stage. To analyse the frequencies and characteristics of injuries and illnesses during the XXI Winter Olympic Games in Vancouver 2010. All National Olympic Committees' (NOC) head physicians were asked to report daily the occurrence (or non-occurrence) of newly sustained injuries and illnesses on a standardised reporting form. In addition, the medical centres at the Vancouver and Whistler Olympic clinics reported daily on all athletes treated for injuries and illnesses. Physicians covering 2567 athletes (1045 females, 1522 males) from 82 NOCs participated in the study. The reported 287 injuries and 185 illnesses resulted in an incidence of 111.8 injuries and 72.1 illnesses per 1000 registered athletes. In relation to the number of registered athletes, the risk of sustaining an injury was highest for bobsleigh, ice hockey, short track, alpine freestyle and snowboard cross (15-35% of registered athletes were affected in each sport). The injury risk was lowest for the Nordic skiing events (biathlon, cross country skiing, ski jumping, Nordic combined), luge, curling, speed skating and freestyle moguls (less than 5% of registered athletes). Head/cervical spine and knee were the most common injury locations. Injuries were evenly distributed between training (54.0%) and competition (46.0%; p=0.18), and 22.6% of the injuries resulted in an absence from training or competition. In skeleton, figure and speed skating, curling, snowboard cross and biathlon, every 10th athlete suffered from at least one illness. In 113 illnesses (62.8%), the respiratory system was affected. At least 11% of the athletes incurred an injury during the games, and 7% of the athletes an illness. The incidence of injuries and illnesses varied substantially between sports.

Systematic review. To systematically review the descriptors used to define running-related musculoskeletal injury and to analyze the implications of different definitions on the results of studies. Studies have developed their own definitions of running-related musculoskeletal injuries based on different criteria. This may affect the rates of injury, which can be overestimated or underestimated due to the lack of a standard definition. Searches were conducted in the Embase, PubMed, CINAHL, SPORTDiscus, LILACS, and SciELO databases, without limits on date of publication and language. Only articles that reported a definition of running-related injury were included. The definitions were classified according to 3 domains and subcategories: (1) presence of physical complaint (symptom, body system involved, region), (2) interruption of training or competition (primary sports involved, extent of injury, extent of limitation, interruption, period of injury), and (3) need for medical assistance. Spearman rank correlation was performed to evaluate the correlation between the completeness of definitions and the rates of injury reported in the studies. A total of 48 articles were included. Most studies described more than half of the subcategories, but with no standardization between the terms used within each category, showing that there is no consensus for a definition. The injury rates ranged between 3% and 85%, and tended to increase with less specific definitions. The descriptors commonly used by researchers to define a running-related injury vary between studies and may affect the rates of injuries. The lack of a standardized definition hinders comparison between studies and rates of injuries.

Multidetector computed tomography (MDCT) characterised by speed and precision is increasingly accessible in emergency wards. The aim of our study was to determine the most common injuries to the chest region, as well as type associated extrathoracic injuries, and the treatment outcome. This prospective study included 61 patients with blunt trauma who were submitted to computed tomography (CT) of the thorax. The number of injuries was evaluated by organs and organ systems of the chest. The cause of the injury, the length and the outcome of the treatment, and the presence of injuries in other regions were assessed. Chest injuries were associated with injuries to other regions in 80.3% cases, predominantly injuries to extremities or pelvic bones in 54.1% cases, followed by head injuries in 39.3% patients. Associated thoracic injuries were present in 90.9% of patients with lethal outcome. Lung parenchymal lesions, pleural effusions and rib fractures were the most common injuries affecting 77.1%, 65.6% and 63.9% of the cases, respectively. Blunt chest trauma is a significant problem affecting predominantly males in their forties and it is usually caused by a motor vehicle accident. In case of pneumomediastinum or mediastinal haematoma, the use of 3D reconstructions is advised for diagnosing possible tracheobronchial ruptures and thoracic aorta injuries. Increased resolution of CT scanners yielded a large number of findings that are occult on radiography, especially in the event of lung parenchymal and pleural injuries. However, none imaging modality can replace surgical judgement.

To describe the MR imaging findings of acute and chronic rectus femoris origin (RFO) injuries. A retrospective review of pelvic and hip MR imaging procedures was performed over a 4-year period for detection of cases with injuries to the RFO. Subjects were classified as having either acute or chronic symptoms. MR imaging studies, radiographs, CT scans, radiology reports, medical records, and operative notes were reviewed. Imaging analysis was directed to assess injuries affecting the direct and indirect heads of the RFO. Concurrent osseous, cartilaginous and musculotendinous injuries were tabulated. The incidence of RFO injuries on MR imaging was 0.5% (17/3160). With the exception of one case of anterior inferior iliac spine apophysis avulsion and partial tear of the direct head of RFO, all subjects had indirect head of RFO injuries (acute injury 8/9, chronic injury 8/8). Partial tear of the direct head of RFO was less frequently seen (acute injury 3/9, chronic injury 2/8). Partial tears of the conjoint tendon were least frequent (acute 1/9, chronic 2/8). No full-thickness tears of the RFO were noted. Associated labral tears were seen in only one case, with no other concomitant abnormality of the articular cartilage or surrounding soft tissues. All RFO injuries were treated non-operatively. Injuries of the RFO are uncommon on MR examinations of pelvis/hips and may occur in a sequence progressing from indirect head injury to involvement of direct head and conjoint tendon in more severe cases.

There is limited data available regarding the cost of firefighter injuries. This information is necessary to develop targeted injury prevention strategies. To categorize the cost of injuries filed in 2012 by firefighters from a from a large department by job duty, injury type, body part affected, and the general motion pattern employed at the time of injury. Data were taken from reports filed by CFD personnel and claims filed with the Workers' Compensation Board (WCB) of Alberta between January 1, 2012 and December 31, 2012. Of the 244 injuries reported, 65% were categorized as sprains and strains, the most frequent of which affected the back (32%). The total cost of all claims was $555,955; 77% were sprain/strain-related. Knee and back injuries were most costly ($157,383 and $100,459). Categorized by job duty, most sprains/strains (31%) were sustained while attending to fire station responsibilities, although physical training was associated with the highest costs (34%). Fireground operations were attributed to 18% of sprains/strains and 16% of costs. Lifting injuries were more frequent (23%) and costly (20%) than all injuries. The most common and costly injuries occurred while attending to fire station-related responsibilities and during physical training.

2012-01-01

The objective of this study was to assemble and synthesize the best available literature from 2004 to 2008 on musculoskeletal injury and pain in dancers. MEDLINE and CINAHL were the primary sources of data. Indexed terms such as dance, dancer, dancing, athletic injuries, occupational injuries, sprains and strains, musculoskeletal diseases, bone density, menstruation disturbances, and eating disorders were used to search the databases. Citations were screened for relevance using a priori criteria, and relevant studies were critically reviewed for scientific merit by the best-evidence synthesis method. After screening, 19 articles were found to be scientifically admissible. Data from accepted studies were abstracted into evidence tables relating to: prevalence and associated factors; incidence and risk factors; intervention; and injury characteristics and prognosis of musculoskeletal injury and pain in dancers. Principal findings included: a high prevalence and incidence of lower extremity, hip and back injuries; preliminary evidence that psychosocial and psychological issues such as stress and coping strategies affect injury frequency and duration; history of a previous lateral ankle sprain is associated with an increased risk of ankle sprain in the contralateral ankle in dance students; fatigue may play a role in ACL injury in dancers; acute hamstring strains in dancers affect tendon more than muscle tissue, often resulting in prolonged absence from dance. It is concluded that, while there are positive developments in the literature on the epidemiology, diagnosis, prognosis, treatment, and prevention of MSK injuries and pain in dancers, much room for improvement remains. Suggestions for future research are offered.

Traumatic orodental injuries are common dental public health problems that have complex aetiology and significant impact on those affected. It is important to understand the frequency, pattern and causes of traumatic orodental injuries so that appropriate and effective treatment services are made available and injury prevention interventions are designed and implemented. The aims of this study were to measure the frequency, causes and patterns of traumatic orodental injuries in patients of all ages treated at the Royal Dental Hospital of Melbourne in Victoria, Australia, over a 12-month period and to investigate the feasibility of establishing an orodental injury surveillance system. For which, a retrospective audit of 304 patient records was undertaken and injury surveillance data were extracted and analysed. Males represented 67% of cases. Three-quarters of all cases were aged less than 24 years. The most frequent cause of orodental injury was falls from less than 1 m or being struck by or colliding with a person or object. Injuries occurred most commonly around the home, on the road, street or footpath, the sports ground and places for recreation and were most often associated with leisure and sports activities. Orodental injuries sustained in one traumatic incident were often multiple and serious. Many severe orodental trauma injury cases present at this public dental hospital are expensive to treat, require long-term management and may be preventable. The findings from this study have led to the development and planned implementation of an enhanced electronic orodental injury structured history form that incorporates the collection of key injury surveillance data. These prospective data are to be combined with injury surveillance data that are routinely collected by all Victorian public hospital emergency departments in order to improve understanding of the nature of orodental injuries impacting Victorian communities and assist with appropriate service

Injuries can counter the beneficial effects of sports participation at a young age if a child or adolescent is unable to continue to participate because of residual effects of injury. This paper reviews current knowledge in the field of long-term health outcomes of youth sports injuries to evaluate the evidence regarding children dropping out of sport due to injury, physeal injuries and growth disturbance, studies of injuries affecting the spine and knee of young and former athletes and surgical outcome of anterior cruciate ligament (ACL) reconstruction in children. Studies of dropping out of sport due to injury are limited primarily to gymnasts and implicate such injuries as ACL rupture and osteochondritis dissecans of the elbow joint in the early retirement of young athletes. Although most physeal injuries resolve with treatment and rest, there is evidence of disturbed physeal growth as a result of injury. Radiological findings implicate the effects of intense physical loading and injury in the development of spinal pathology and back pain during the growth of youth athletes; however, long-term effects are unclear. Follow-up studies of young athletes and adults indicate a high risk of osteoarthritis after meniscus or ACL injury. Prospective cohort studies with a follow-up into adulthood are needed to clarify the long-term health outcomes of youth sports injuries. Important to this research is meticulous documentation of injuries on injury report forms that include age-appropriate designations of the type of injury and accurate determination of exposure-based injury rates.

Cartilage Injuries in the Adult Knee

Science.gov (United States)

Moyad, Thomas F.

2011-01-01

Cartilage injuries are frequently recognized as a source of significant morbidity and pain in patients with previous knee injuries. The majority of patients who undergo routine knee arthroscopy have evidence of a chondral defect. These injuries represent a continuum of pathology from small, asymptomatic lesions to large, disabling defects affecting a major portion of one or more compartments within the knee joint. In comparison to patients with osteoarthritis, individuals with isolated chondral surface damage are often younger, significantly more active, and usually less willing to accept limitations in activities that require higher impact. At the present time, a variety of surgical procedures exist, each with their unique indications. This heterogeneity of treatment options frequently leads to uncertainty regarding which techniques, if any, are most appropriate for patients. The purpose of this review is to describe the workup and discuss the management techniques for cartilage injuries within the adult knee. PMID:26069581

2016-07-12

Stanniocalcin-1 (STC-1) protects against renal ischemia-reperfusion injury (RIRI). However, the molecular mechanisms remain widely unknown. STC-1 inhibits reactive oxygen species (ROS), whereas most ROS-mediated pathways are associated with ischemic injury. Therefore, to explore the mechanism, the effects of STC-1 on ROS-medicated pathways were studied. Non-traumatic vascular clamps were used to establish RIRI mouse models. The serum levels of STC-1, interleukin-6 (IL-6), interferon (IFN) γ, P53, and capase-3 were measured by ELISA kits. Superoxide dismutase (SOD) and malondialdehyde (MDA) were measured by fluorescence spectrofluorometer. All these molecules changed significantly in a RIRI model mouse when compared with those in a sham control. Kidney cells were isolated from sham and model mice. STC-1 was overexpressed or knockout in these kidney cells. The molecules in ROS-medicated pathways were measured by real-time quantitative PCR and Western blot. The results showed that STC-1 is an effective ROS scavenger. The serum levels of STC-1, MDA and SOD activity were increased while the serum levels of IL-6, iIFN-γ, P53, and capase-3 were decreased in a model group when compared with a sham control (p ROS-mediated molecules. Therefore, STC-1 maybe improve anti-inflammation, anti-oxidant and anti-apoptosis activities by affecting ROS-mediated pathways, especially the phospho-modifications of the respective proteins, resulting in the increase of SOD and reduce of capase-3, p53, IL-6 and IFN-γ.

Diagnosing Achilles tendon injuries in the emergency department.

LENUS (Irish Health Repository)

Gibbons, Lynda

2013-09-01

Achilles tendon (AT) injury is an overuse injury often seen in professional and recreational athletes. It tends to affect men, particularly those in their thirties and forties, more than women, and is typically seen in people who are intermittently active. To ensure AT ruptures are identified and treated effectively, early intervention in emergency departments (EDs) is crucial. This article discusses how advanced nurse practitioners can use their comprehensive problem-solving, clinical decision-making and clinical judgement skills to manage patients who present with suspected AT injury. It also describes the anatomy of tendon rupture, the aetiology and mechanism of injuries, and the importance of assessment and diagnostic tools, therapeutic techniques and management strategies. Finally, it considers the psychological effect this injury can have on patients, while in the ED and after discharge. A case study is included as an example of ED management.

What kinds of injuries do OSHA inspections prevent?

2010-08-01

OSHA's enforcement program is one of the major public efforts to protect American workers. We examine both the scope of injury prevention that inspections can contribute and the types of standards that contribute the most. We linked Pennsylvania Department of Labor and Industry files for lost-time injuries and employment to calculate injury rates for 1998-2005 for all single-establishment manufacturing firms. We linked these to OSHA inspection records. Inspections with penalties did affect injury types unrelated to standards as well as those related. We also found again that citations for violations of the standard requiring personal protective equipment had the largest impact on preventing injuries. Programs requiring protective equipment use deserve added attention from consultants and inspectors. In addition, some inspections spur managers to undertake safety measures that go beyond compliance with standards. 2010 Elsevier Ltd. All rights reserved.

Traumatic Brain Injuries during Development: Implications for Alcohol Abuse

Directory of Open Access Journals (Sweden)

Zachary M. Weil

2017-07-01

Full Text Available Traumatic brain injuries are strongly related to alcohol intoxication as by some estimates half or more of all brain injuries involve at least one intoxicated individual. Additionally, there is mounting evidence that traumatic brain injuries can themselves serve as independent risk factors for the development of alcohol use disorders, particularly when injury occurs during juvenile or adolescent development. Here, we will review the epidemiological and experimental evidence for this phenomenon and discuss potential psychosocial mediators including attenuation of negative affect and impaired decision making as well as neurochemical mediators including disruption in the glutamatergic, GABAergic, and dopaminergic signaling pathways and increases in inflammation.

An injury of cruciate ligament is one the most common knee injuries. This accident happens mostly without external impact and towards the end of training and competition sessions. Women, especially athletes playing team sports ball games such as soccer or disciplines such as tennis, are affected 2 to 8 times more often than men. Anatomic, biomechanical and endocrinological differences are currently discussed as potential risk factors. In terms of prevention, biomechanical impact is of greatest importance given its influenceability through various training opportunities. Training programs including endurance aspects, strengthening knee musculature, balance as well as plyometric trainings were most effective. Further studies should focus more on concomitants of course of injuries. © Georg Thieme Verlag KG Stuttgart · New York.

Context: Lower extremity injuries are common in basketball, yet it is unclear how prophylactic interventions affect lower extremity injury incidence rates. Objective: To analyze the effectiveness of current lower extremity injury prevention programs in basketball athletes, focusing on injury rates of (1) general lower extremity injuries, (2) ankle sprains, and (3) anterior cruciate ligament (ACL) tears. Data Sources: PubMed, MEDLINE, CINAHL, SPORTDiscus, and the Cochrane Register of Controlled Trials were searched in January 2015. Study Selection: Studies were included if they were randomized controlled or prospective cohort trials, contained a population of competitive basketball athletes, and reported lower extremity injury incidence rates specific to basketball players. In total, 426 individual studies were identified. Of these, 9 met the inclusion criteria. One other study was found during a hand search of the literature, resulting in 10 total studies included in this meta-analysis. Study Design: Systematic review and meta-analysis. Level of Evidence: Level 2. Data Extraction: Details of the intervention (eg, neuromuscular vs external support), size of control and intervention groups, and number of injuries in each group were extracted from each study. Injury data were classified into 3 groups based on the anatomic diagnosis reported (general lower extremity injury, ankle sprain, ACL rupture). Results: Meta-analyses were performed independently for each injury classification. Results indicate that prophylactic programs significantly reduced the incidence of general lower extremity injuries (odds ratio [OR], 0.69; 95% CI, 0.57-0.85; P basketball athletes. Conclusion: In basketball players, prophylactic programs may be effective in reducing the risk of general lower extremity injuries and ankle sprains, yet not ACL injuries. PMID:26502412

Cerebral responses to traumatic brain injury (TBI) include up- and downregulation of a vast number of proteins involved in endogenous inflammatory responses and defense mechanisms developing postinjury. The present study analyzed the global gene expression profile in response to cryo-induced TBI...... at various time-points postlesion (6 h, 1 day and 4 days). The effects of injury, treatment, and injury-treatment interaction were observed. TBI alone rendered a large number of genes affected. Analysis of lesion and treatment interactions resulted in a clear effect of the interaction between injury and FGL......-treatment compared to injury and placebo-treatment. Genes affected by TBI alone included inflammation markers, protein kinases, ion channel members and growth factors. Genes encoding regulators of apoptosis, signal transduction and metabolism were altered by the interaction between FGL-treatment and TBI. FGL...

To discuss the efficiency of RTS (Revised TraumaScore), ISS (Injury Severity Score), and factors that affect mortality and morbidity in gastrointestinal injuries due to blunt trauma.Method and methods: Patients with gastrointestinal injuries due to blunt trauma operated within the last six years have been studied retrospectively in terms of demographics,injury mechanism and localization, additional injuries, RTS and ISS, operative technique, morbidity, mortality and duration of hospitalization. Of the eighteen cases, cause of injury was a traffic accident for 11 (61.1%), fall from height for 5 (27%) and physical attack for 2 (11%). Among the eighteen patients,there were 21 gastrointestinal injuries (11 intestinal, 6 colon,3 duodenum, 1 stomach). 10 (55.6%) had additional intraabdominal injuries while the number for extra-abdominal injuries were 12 (66.7%). Primary suture (10), segmentary resection (9) and pyloric exclusion (2) were the operations performed for the twenty-one gastrointestinal injuries.Although statistically not significant, 13(72.2%) patients with additional injuries compared with 5 (27.8%) patients with isolated gastrointestinal injuries, were found to have lower RTS (7.087/7.841), higher ISS (19.4/12.2), longer duration of hospitalization (11.5/8.4 day) as well as higher morbidity (7/1) and mortality (2/0) rates. Comparing the RTS (7.059/7.490) of patients who have and have not developed morbidity revealed no significant difference.However, ISS (23.9/12.2) was significantly higher in patients who have developed morbidity (p=0.003). RTS (6.085 7.445) and ISS (39.5/14.6) of patients who have survived were significantly different than patients who have not(p=0.037 and p=0.023, respectively) Additional injuries in patients with gastrointestinal injury due blunt abdominal traumas increases, although not significantly, morbidity, mortality and duration of hospitalization even when operated early. High ISS is significantly related to the risk of both

Traumatic Brain Injury Pathophysiology and Treatments: Early, Intermediate, and Late Phases Post-Injury

Traumatic Brain Injury (TBI) affects a large proportion and extensive array of individuals in the population. While precise pathological mechanisms are lacking, the growing base of knowledge concerning TBI has put increased emphasis on its understanding and treatment. Most treatments of TBI are aimed at ameliorating secondary insults arising from the injury; these insults can be characterized with respect to time post-injury, including early, intermediate, and late pathological changes. Early pathological responses are due to energy depletion and cell death secondary to excitotoxicity, the intermediate phase is characterized by neuroinflammation and the late stage by increased susceptibility to seizures and epilepsy. Current treatments of TBI have been tailored to these distinct pathological stages with some overlap. Many prophylactic, pharmacologic, and surgical treatments are used post-TBI to halt the progression of these pathologic reactions. In the present review, we discuss the mechanisms of the pathological hallmarks of TBI and both current and novel treatments which target the respective pathways. PMID:24381049

To prospectively study mechanisms and injury characteristics of ocular firework burns. A prospective analysis of all patients with firework injuries attending the Department of Ophthalmology, University of Vienna, between 1994 and 2001. We looked for classes of fireworks and mechanisms of injuries. The number of diagnoses was established and their severity classified. During this period (8 years) we identified 116 eyes of 102 patients. 67/102 (66%) of all injuries were caused by class II and III fireworks. Patients ranged between 4 and 83 years. Ocular injuries occurred more frequently in males (69, 68%) and affected the right eye in 53 patients (52.5%). Ocular firework injuries to minors (under the age of 18 years) occurred in 48 (49%). The most common types of injury were skin and corneal erosions and abrasions (32/116, 28%). 11/116 eyes (10%) had severe injuries. 8 of 11 severe injuries (72%) occurred in minors (<18 years). 2 patients (1.7%) developed permanent blindness. In 32/116 patients (28%), the ocular trauma resulted in visual impairment, mainly due to corneal scars or retinal pathologies. In all patients, the severity index was 1.4 +/- 0.8. In minors the severity index was 1.6 +/- 1.0, in adults 1.2 +/- 0.5 (p = 0.013). Injuries in minors were significantly more severe than those in adults. Possible preventive measures include legislation, education of minors and eye protection. Copyright 2002 S. Karger AG, Basel

We investigated the effect of leaf age on the response of net photosynthesis (A), stomatal conductance (g wv ), foliar injury, and leaf nitrogen concentration (N L ) to tropospheric ozone (O 3 ) on Prunus serotina seedlings grown in open-plots (AA) and open-top chambers, supplied with either carbon-filtered or non-filtered air. We found significant variation in A, g wv , foliar injury, and N L (P 3 treatments. Seedlings in AA showed the highest A and g wv due to relatively low vapor pressure deficit (VPD). Older leaves showed significantly lower A, g wv , N L , and higher foliar injury (P wv , and foliar injury to O 3 . Both VPD and N L had a strong influence on leaf gas exchange. Foliar O 3 -induced injury appeared when cumulative O 3 uptake reached 8-12 mmol m -2 , depending on soil water availability. The mechanistic assessment of O 3 -induced injury is a valuable approach for a biologically relevant O 3 risk assessment for forest trees. - Ozone effects on symptom development and leaf gas exchange interacted with leaf age and N-content on black cherry seedlings.

Although physical activity brings a range of lifelong health benefits, it may also lead to injuries that pose a significant threat to health. It is particularly noticeable in people involved in professional sports where sport-related injuries commonly occur and are associated with intense exercise which aims to improve physical fitness. The article attempts to determine incidence of sports injuries reported by Plus League volleyball players, as well as to identify their most common types and causes. The research project involved 90 Plus League volleyball players aged 18-37 with the average age of 25.11 (SD±5.378). A method of diagnostic survey was applied to collect empirical data by means of questionnaire developed by the authors (researchers). The results were statistically analysed and verified with the analysis of variance (ANOVA) and χ2 test at the significance level (or critical P-value) of P≤0.05. Over 87% of the respondents suffered from at least one sport-related injury. In total, 362 injuries occurred, on average 4.02 injuries per one volleyball player. The most common sports injuries involved ankle or talocrural joint (46 injuries), knee and lower leg muscles (30), interphalangeal articulations of fingers (30) as well as shoulder joint. More than half of the injuries (57%) occurred twice or three times. Volleyball players commonly sustain injuries through contact with an opposing player in competition. Sport-specific injuries may also occur due to exhaustion, lack of rest and undertreated injuries. The most common volleyball-related injuries are primarily talocrural joint, hand and shoulder injuries. Common types of injuries that can affect volleyball players include muscles, joints and ligaments injuries, sprains and strains as well as bruises. Most of these injuries are caused by exhaustion, contact with an opposing player during competition and fatigue. The incidence of sport-related injuries seems to be influenced by such factors as somatic

Rubber projectiles are used as an alternative to metal bullets owing to their lower morbidity and mortality rate. There are few reports of vascular lesions of extremities caused by rubber projectiles in the literature. The authors report the case of a 37-year-old man who was the victim of a penetrating injury to the left thigh with a rubber projectile. He reported only pain at the site of the injury; pulses were decreased in the affected limb. After arteriography confirmed an injury to the superficial femoral artery, he underwent an arterial and venous femorofemoral bypass using a reversed contralateral saphenous vein.

Full Text Available Introduction: “polytrauma” patients are higher risk of complications and death than the summation of expected mortality and morbidity of their individual injuries. The ideal goal in trauma resuscitation care is to identify and treat all injuries. With clinical and technological advanced imaging available for diagnosis and treatment of traumatic patients, missed injuries still significant affect modern trauma services and its outcome. Aim: to improve outcome and determine the incidence and nature of missed injuries in polytrauma patients. Methods: the study is a cross-sectional, prospective study included 600 polytraumatized patients admitted in Suez Canal University Hospital. Firstly assessed and treated accordingly to Advanced Trauma Life Support (ATLS guidelines and treat the life threading conditions if present with follow-up short outcome for 28 days. Results: The most common precipitate factor for missed injuries in my study was clinical evaluation error due to Inadequate diagnostic workup in 42.9%. And the second risk factor was Deficiency in Physical Examination in 35.7%. Lastly Incomplete assessment due to patient instability in 10.7% and incorrect interpretation of imaging10.7%.low rates of missed injuries (40.8% in patients arriving during the day compared with (59.2% of night arrivals. Conclusion: the incidence of missed injuries in the study is 9.0 % which is still high compared to many trauma centers. And mostly increase the period of stay in the hospital and affect the outcome of polytrauma patients.

Violence and injuries are under-reported in developing countries, especially during natural disasters such as floods. Compounding this, affected areas are isolated from the rest of the country. During 2007 Bangladesh experienced two consecutive floods which affected almost one-third of the country. The objective of this study was to examine unintentional injuries to children in rural Bangladesh and parental violence against them during floods, and also to explore the association of socioeconomic characteristics. A cross-sectional rural household survey was conducted in the worst flood-affected areas. A group of 638 randomly selected married women of reproductive age with at least one child at home were interviewed face-to-face using pre-tested structured questionnaires. The chi2 test and logistic regression were used for data analysis. The majority of families (90%) were affected by the flood and were struggling to find food and shelter, resulting in the parents becoming violent towards their children and other family members in the home. Cuts (38%), falls (22%) and near drowning (21%) comprised the majority of unintentional injuries affecting children during the floods. A large number of children were abused by their parents during the floods (70% by mothers and 40% by fathers). The incidence of child injuries and parental violence against children was higher among families living in poor socio-economic conditions, whose parents were of low occupational status and had micro-credit loans during the floods. Floods can have significant effects on childhood injury and parental violence against children. The improvement of socio-economic conditions would assist in preventing child injuries and parental violence.

Despite their wealth and modern road systems, traffic injury rates in Middle Eastern countries are generally higher than those in Western countries. The authors examined traffic injuries in Qatar during 2000–2010, a period of rapid population growth, focusing on the impact of speed control cameras installed in 2007 on overall injury rates and mortality. During the period 2000–2006, prior to camera installation, the mean (SD) vehicular injury death rate per 100 000 was 19.9±4.1. From 2007 to 2010, the mean (SD) vehicular death rates were significantly lower: 14.7±1.5 (p=0.028). Non-fatal severe injury rates also declined, but mild injury rates increased, perhaps because of increased traffic congestion and improved notification. It is possible that speed cameras decreased speeding enough to affect the death rate, without affecting overall injury rates. These data suggest that in a rapidly growing Middle Eastern country, photo enforcement (speed) cameras can be an important component of traffic control, but other measures will be required for maximum impact.

Donnellan, Clare P

2006-09-01

This case report describes the use of acupuncture in the management of chronic central pain in a 51 year old man following severe traumatic brain injury and multiple injuries including rib fractures. The patient reported rapid and significant improvements in pain and mood during a course of acupuncture treatment. Chronic pain following traumatic brain injury is a significant problem. Chronic pain after rib fractures is also commonly reported. Acupuncture is widely used in the management of pain but its use has been reported rarely in the traumatic brain injury literature. This case report suggests that acupuncture may be a useful option to consider in these patients. Outcome was assessed formally using a 0-10 verbal numerical rating scale for pain, and the Hospital Anxiety and Depression Scale (HADS) for psychological status before and after the course of treatment. These scales are widely used in clinical practice as well as in research involving patients with traumatic brain injury, although they have not been validated in this population. The changes in this patient's outcome scores were not consistent with the benefits he reported. Treatment of this patient highlighted the difficulties of using standardised self rating scales for patients with cognitive impairment. The report also discusses the effects of acupuncture on this patient's mood.

2008-05-01

Occupational injuries in mines are attributed to many factors. In this study, an attempt was made to identify the various factors related to work injuries in mines and to estimate their effects on work injuries to mine workers. An accident path model was developed to estimate the pattern and strength of relationships amongst the personal and sociotechnical variables in accident/injury occurrences. The input data for the model were the correlation matrix of 18 variables, which were collected from the case study mines. The case study results showed that there are sequential interactions amongst the sociotechnical and personal factors leading to accidents/injuries in mines. Amongst the latent endogenous constructs, job dissatisfaction and safe work behaviour show a significant positive and negative direct relationship with work injury, respectively. However, the construct safety environment has a significant negative indirect relationship with work injury. The safety environment is negatively affected by work hazards and positively affected by social support. The safety environment also shows a significant negative relationship with job stress and job dissatisfaction. However, negative personality has no significant direct or indirect effect on work injury, but it has a significant negative relationship with safe work behaviour. The endogenous construct negative personality is positively influenced by job stress and negatively influenced by social support.

Full Text Available Abstract Background Knowledge is sparse concerning injuries affecting rural populations in low and middle-income countries in general and in Iran in particular. This study documents the incidence and characteristics of severe injuries affecting rural people in the Iranian district of Twiserkan and it investigates these people's suggestions for injury prevention and control. Methods An interview-based investigation was undertaken that comprised all unintentional injuries leading to hospitalization (more than 6 hours or death that had occurred within a twelve month period and that were identified in the files of the 62 "health houses" of the Twiserkan district. For each case, semi-structured interviews were conducted at the households of the injured people (134 injuries affecting 117 households were identified. Results The incidence rates of fatal and non-fatal injuries were respectively 4.1 and 17.2 per 10 000 person-years and, as expected, men were more affected than women (77.6% of all injury cases. Traffic injuries (in particular among motorcyclists were as common as home-related injuries but they were far more fatal. Among common suggestions for prevention, people mentioned that the authorities could work on the design and engineering of the infrastructure in and around the village, that the rural health workers could contribute more with local information and education and that the people themselves could consider behaving in a safer manner. Conclusion Not only domestic injuries but also those in traffic are an important cause of severe and fatal injury among rural people. Health workers may play an important role in injury surveillance and in identifying context-relevant means of prevention that they or other actors may then implement.

Basketball injuries in children

International Nuclear Information System (INIS)

Gaca, Ana Maria

2009-01-01

Basketball is a popular, worldwide sport played outdoors and indoors year-round. Patterns of injury are related to abrupt changes in the athlete's direction, jumping, contact between athletes, the hard playing surface and paucity of protective equipment. Intensity of play and training in the quest of scholarships and professional careers is believed to contribute to an increasing occurrence of injury. Radiologists' appreciation of the breadth of injury and its relation to imaging and clinical findings should enhance the care of these children. Some of the patterns of injury are well known to radiologists but vary due to age- and size-related changes; the growing skeleton is affected by differing susceptibilities from biomechanical stresses at different sizes. Beyond screening radiographs, the accuracy of MRI and CT has improved diagnosis and treatment plans in this realm. Investigations to detect symptoms and signs in an attempt to prevent the tragedy of sudden cardiac death in basketball players may lead to MRI and CTA studies that compel radiologists to evaluate cardiac function along with myocardial and coronary artery anatomy. Worthy of mention also is the female athlete triad of disordered eating, amenorrhea, and osteoporosis that is observed in some young women participating in this and other sports. (orig.)

Local freezing cold injuries are common in the north and sequelae to cold injury can persist many years. Quantitative sensory testing (QST) can be used to assess neurosensory symptoms but has previously not been used on cold injury patients. To evaluate neurosensory sequelae after local freezing cold injury by thermal and vibrotactile perception thresholds and by symptom descriptions. Fifteen patients with a local freezing cold injury in the hands or feet, acquired during military training, were studied with QST by assessment of vibrotactile (VPT), warmth (WPT) and cold (CPT) perception thresholds 4 months post-injury. In addition, a follow-up questionnaire, focusing on neurovascular symptoms, was completed 4 months and 4 years post-injury. QST demonstrated abnormal findings in one or both affected hands for VPT in 6 patients, for WPT in 4 patients and for CPT in 1 patient. In the feet, QST was abnormal for VPT in one or both affected feet in 8 patients, for WPT in 6 patients and for CPT in 4 patients. Freezing cold injury related symptoms, e.g. pain/discomfort when exposed to cold, cold sensation and white fingers were common at 4 months and persisted 4 years after the initial injury. Neurosensory sequelae after local freezing cold injury, in terms of abnormal thermal and/or vibration perception thresholds, may last at least 4 months after the initial injury. Symptoms such as pain/discomfort at cold exposure, cold sensations and white fingers may persist at least 4 years after the initial injury.

The purpose of this study was to compare the injury patterns and incidence of snowboarding and ski boarding injuries with that of alpine skiing in 2000 to 2005, as there are few previous studies comparing these 3 sports, especially in Asia. The injury patterns are different among the 3 snow sports. Descriptive epidemiology study. The subjects were alpine skiers (1240 cases), snowboarders (2220 cases), and ski boarders (132 cases) who were injured in 2 ski resorts located in Niigata prefecture in Japan and visited the authors' clinics in these ski resorts between 2000 and 2005. On visiting the clinics, patients completed a questionnaire reviewing the circumstances surrounding the injury event, and physicians documented the diagnosis. The injury rate, which was based on all purchased lift tickets, in snowboarding decreased gradually, although it was still 2 times higher than that of alpine skiing. Snowboarding and ski boarding had a higher fracture and dislocation rate. Both sports also had a 4 times higher rate of injuries because of jumping. The characteristics of ski boarding were a lower head and neck injury rate and collision injury rate than those of the other 2 snow sports, as well as a 2 times higher rate of fractures compared with alpine skiing injuries and a 1.4 times higher incidence than that of snowboarding injuries. Of the fractures caused by ski boarding accidents, 39.6% affected the lower leg bones. Injury prevention strategies should focus on jumps for snowboarders and ski boarders.

To identify the patterns of ocular injury and to determine ocular morbidity resulting from the use of firecrackers. A prospective observational study of all patients presenting with ocular trauma consequent to fireworks usage in a tertiary eye care center in South India over a one-month period around the autumn festival of Diwali. We also reviewed the published literature from around the world reporting ocular injuries due to firecrackers. 49 patients were included in the study, out of which the vast majority (40/81%) were males. The mean age was 17 years. Almost an equal number of bystanders (24/48.9%) was affected as compared to people handling the fireworks (25/51%). 13 (26.53%) patients had open-globe injury whereas 33 (67.34%) patients had closed-globe injury. Twenty-two (44.8%) patients underwent surgical intervention. Eighteen (36.7%) patients had final vision less then 20/40 (range = 20/50 to No Perception of Light) with eight patients having no perception of light in the affected eye. Unregulated use of firecrackers can lead to significant ocular morbidity, mainly involving children, young males, and even innocent bystanders. A combination of public awareness and appropriate legislative laws should be formulated regarding the use of fireworks to decrease the load of needless blindness on society.

The present study explored the factors effective on colon-related morbidity in patients with penetrating injury of the colon. The medical records of 196 patients were reviewed for variables including age, gender, factor of trauma, time between injury and operation, shock, duration of operation, Penetrating Abdominal Trauma Index (PATI), Injury Severity Score (ISS), site of colon injury, Colon Injury Score, fecal contamination, number of associated intra- and extraabdominal organ injuries, units of transfused blood within the first 24 hours, and type of surgery. In order to determine the independent risk factors, multivariate logistic regression analysis was performed. Gunshot wounds, interval between injury and operation > or =6 hours, shock, duration of the operation > or =6 hours, PATI > or =25, ISS > or =20, Colon Injury Score > or = grade 3, major fecal contamination, number of associated intraabdominal organ injuries >2, number of associated extraabdominal organ injuries >2, multiple blood transfusions, and diversion were significantly associated with morbidity. Multivariate logistic regression analysis showed diversion and transfusion of > or =4 units in the first 24 hours as independent risk factors affecting colon-related morbidity. Diversion and transfusion of > or =4 units in the first 24 hours were determined to be independent risk factors for colon-related morbidity.

This paper evaluates 420 ski injuries occurring in Northern Sweden in 1977. Our main aim was to correlate knee injuries with types of skiing and to note a change in incidence with evolution of equipment. Fifty-eight lesions (13.8%) affected the knee joint which is about the same frequency as 10 years earlier nor has introduction of high stiff boots in downhill skiing increased incidence of knee injuries. Cross-country and long-distance skiing produced more knee injuries (24.7%) than downhill skiing (11.4%). Cross-country skiers were older and more women in this group sustained knee injuries. The use of non-release type bindings is probably the main reason for this higher incidence but age and different skiing techniques seem to contribute.

Studies on the injuries of crops by harmful gases under covering. I. Injuries of vegetables by gaseous nitrogen dioxide and the conditions affecting crop susceptibility. [Eggplant

The effects of environmental conditions such as soil-moisture humidity, and light on injuries to crops such as kidney bean, cucumber, tomato, and egg plant as well as the relationships between injury occurrence and plant nutrition, age of seedlings, and leaf position were investigated when the crops were exposed to gaseous nitrogen dioxide under a covering. The injury was severer when the soil moisture was richer and the humidity was higher. Injury was greater under dark conditions as opposed to light conditions before, during, and after NO/sub 2/ exposure. The first leaves of kidney bean plants were more susceptible to the gas when they were younger. Leaves with active metabolism (in the middle position) were the most susceptible to NO/sub 2/. Vegetables grown in fields or cultures poor in nitrogen were apparently susceptible to the gas, and those grown in ammonia-nitrogen rich cultures were more severely injured than those grown on nitrate-nitrogen rich cultures. Those grown in iron-deficient cultures were more susceptible to NO/sub 2/ than controls.

Intraoperative positioning injuries during shoulder- and knee arthroscopy are rare complications and affect mainly nerves and soft tissue. Although the majority of these complications are reversible, in some cases serious negative consequences for the patient persist. This article describes the frequency of several positioning injuries including their prevention and the appropriate treatment. The legal responsibilities are illustrated as well as the importance of an intense preoperative investigation of preexisting diseases and possible risk factors. Furthermore, a review of possible thermal injuries of the patient during arthroscopy caused by e.g. electrosurgical instruments or the cold light source, is given as well as prevention strategies.

Introduction Although death due to electrical injury and lightning are rare in children, these injuries are often preventable. Twenty years ago, most injuries occurred at home, precipitated by oral contact with electrical cords, contact with wall sockets and faulty electrical equipment. We sought to assess the epidemiology of electrical injuries in children presenting to Emergency Departments (EDs) that participate in the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP). This study is a retrospective review of electrical and lightning injury data from CHIRPP. The study population included children and youth aged 0-19 presenting to participating CHIRPP EDs from 1997-2010. Age, sex, year, setting, circumstance and disposition were extracted. Variables were tested using Fisher's exact test and simple linear regression. The dataset included 1183 electrical injuries, with 84 (7%) resulting in hospitalization. Most events occurred at home in the 2-5 year age group and affected the hands. Since 1997 there has been a gradual decrease in the number of electrical injuries per year (plightning were rare (n=19). No deaths were recorded in the database. Despite the decrease in the number of electrical injuries per year, a large portion of injuries still appear to be preventable. Further research should focus on effective injury prevention strategies.

Most studies examining suture line failure after penetrating colon injuries have focused on right- versus left-sided injuries. In our institution, operative decisions (resection plus anastomosis vs. diversion) are based on a defined management algorithm regardless of injury location. The purpose of this study was to evaluate the effect of injury location on outcomes after penetrating colon injuries. Consecutive patients with full thickness penetrating colon injuries for 13 years were stratified by age, injury location and mechanism, and severity of shock. According to the algorithm, patients with nondestructive injuries underwent primary repair. Destructive wounds underwent resection plus anastomosis in the absence of comorbidities or large preoperative or intraoperative transfusion requirements (>6 U of packed red blood cells); otherwise, they were diverted. Injury location was defined as ascending, transverse, descending (including splenic flexure), and sigmoid. Multivariable logistic regression was performed to determine whether injury location was an independent predictor of either morbidity or mortality. Four hundred sixty-nine patients were identified: 314 (67%) underwent primary repair and 155 (33%) underwent resection. Most injuries involved the transverse colon (39%), followed by the ascending colon (26%), the descending colon (21%), and the sigmoid colon (14%). Overall, there were 13 suture line failures (3%) and 72 abscesses (15%). Most suture line failures involved injuries to the descending colon (p = 0.06), whereas most abscesses followed injuries to the ascending colon (p = 0.37). Multivariable logistic regression failed to identify injury location as an independent predictor of either morbidity or mortality after adjusting for 24-hour transfusions, base excess, shock index, injury mechanism, and operative management. Injury location did not affect morbidity or mortality after penetrating colon injuries. Nondestructive injuries should be primarily

This study was undertaken to analyze the characteristics and risk factors relating to fatalities and injuries caused by paragliding. The judicial examination reports and hospital documents of 82 patients traumatized in 64 accidents during 242 355 paragliding jumps between August 2004 and September 2011 were analyzed. In these accidents, 18 of the 82 patients lost their lives. In the patients with a confirmed cause of accident, most of them were involved with multiple fractures and internal organ injuries (n=8, 44.4%). We investigated the incidence of paragliding injuries, the types of the injuries, and the severity of affected anatomical regions. The findings are significant for the prevention of paragliding injuries and future research.

Soft tissue twisting injuries of the knee

Magee, T.; Shapiro, M.

Twisting injuries occur as a result of differential motion of different tissue types in injuries with some rotational force. These injuries are well described in brain injuries but, to our knowledge, have not been described in the musculoskeletal literature. We correlated the clinical examination and MR findings of 20 patients with twisting injuries of the soft tissues around the knee. Design and patients: We prospectively followed the clinical courses of 20 patients with knee injuries who had clinical histories and MR findings to suggest twisting injuries of the subcutaneous tissues. Patients with associated internal derangement of the knee (i.e., meniscal tears, ligamentous or bone injuries) were excluded from this study. MR findings to suggest twisting injuries included linear areas of abnormal dark signal on T1-weighted sequences and abnormal bright signal on T2-weighted or short tau inversion recovery (STIR) sequences and/or signal to suggest hemorrhage within the subcutaneous tissues. These MR criteria were adapted from those established for indirect musculotendinous junction injuries. Results: All 20 patients presented with considerable pain that suggested internal derangement on physical examination by the referring orthopedic surgeons. All presented with injuries associated with rotational force. The patients were placed on a course of protected weight-bearing of the affected extremity for 4 weeks. All patients had pain relief by clinical examination after this period of protected weight-bearing. Twisting injuries of the soft tissues can result in considerable pain that can be confused with internal derangement of the knee on physical examination. Soft tissue twisting injuries need to be recognized on MR examinations as they may be the cause of the patient's pain despite no MR evidence of internal derangement of the knee. The demonstration of soft tissue twisting injuries in a patient with severe knee pain but no documented internal derangement on MR

Full Text Available Background. Nitric oxide (NO-signal transduction plays an important role in renal ischemia/reperfusion (I/R injury. NO produced by endothelial NO-synthase (eNOS has protective functions whereas NO from inducible NO-synthase (iNOS induces impairment. Rosiglitazone (RGZ, a peroxisome proliferator-activated receptor (PPAR-γ agonist exerted beneficial effects after renal I/R injury, so we investigated whether this might be causally linked with NOS imbalance. Methods. RGZ (5 mg/kg was administered i.p. to SD-rats (f subjected to bilateral renal ischemia (60 min. Following 24 h of reperfusion, inulin- and PAH-clearance as well as PAH-net secretion were determined. Morphological alterations were graded by histopathological scoring. Plasma NOx-production was measured. eNOS and iNOS expression was analyzed by qPCR. Cleaved caspase 3 (CC3 was determined as an apoptosis indicator and ED1 as a marker of macrophage infiltration in renal tissue. Results. RGZ improves renal function after renal I/R injury (PAH-/inulin-clearance, PAH-net secretion and reduces histomorphological injury. Additionally, RGZ reduces NOx plasma levels, ED-1 positive cell infiltration and CC3 expression. iNOS-mRNA is reduced whereas eNOS-mRNA is increased by RGZ. Conclusion. RGZ has protective properties after severe renal I/R injury. Alterations of the NO pathway regarding eNOS and iNOS could be an explanation of the underlying mechanism of RGZ protection in renal I/R injury.

Lisfranc injuries result from high- and low-energy mechanisms though the literature has been more focused on high-energy mechanisms. A comparison of high-energy (HE) and low-energy (LE) injury patterns is lacking. The objective of this study was to report injury patterns in LE Lisfranc joint injuries and compare them to HE injury patterns. Operative Lisfranc injuries were identified over a 5-year period. Patient demographics, mechanism of injury, injury pattern, associated injuries, missed diagnoses, clinical course, and imaging studies were reviewed and compared. HE mechanism was defined as motor vehicle crash, motorcycle crash, direct crush, and fall from greater than 4 feet and LE mechanism as athletic activity, ground level twisting, or fall from less than 4 feet. Thirty-two HE and 48 LE cases were identified with 19.3 months of average follow-up. There were no differences in demographics or missed diagnosis frequency (21% HE vs 18% LE). Time to seek care was not significantly different. HE injuries were more likely to have concomitant nonfoot fractures (37% vs 6%), concomitant foot fractures (78% vs 4%), cuboid fractures (31% vs 6%), metatarsal base fractures (84% vs 29%), displaced intra-articular fractures (59% vs 4%), and involvement of all 5 rays (23% vs 6%). LE injuries were more commonly ligamentous (68% vs 16%), with fewer rays involved (2.7 vs 4.1). LE mechanisms were a more common cause of Lisfranc joint injury in this cohort. These mechanisms generally resulted in an isolated, primarily ligamentous injury sparing the lateral column. Both types had high rates of missed injury that could result in delayed treatment. Differences in injury patterns could help direct future research to optimize treatment algorithms. Level III, comparative series.

This study will present trends and recommendations to increase active and passive safety in paragliding on the basis of current state-of-the-art equipment and typical patterns of injury. This German-Swiss teamwork presents data of 55 male and 9 female patients treated after paragliding accidents between 1994 to 1998 respectively 1996 to 1998. 43.7% of the pilots presented with multiple injuries, 62.5% suffered spinal fractures and 18.8% pelvic fractures. 28.4% of the injured pilots were admitted with injuries of the lower extremities mainly affecting the tarsus or the ankle joint. Only three patients with single injuries could be treated in an ambulatory setting. 54.0% of the injuries left the patients with lasting functional residues and complaints. Main causes of accidents were either pilot error in handling the paraglider or general lack of awareness about potential risk factors. 46.0% of injuries occurred during landing, 42.9% of injuries during the flight and another 11.1% of injuries during starting procedures. With noticeable enhanced performance sails of the beginners and intermediate level are increasingly popular. Protective helmets and sturdy footwear reaching above the ankle joint are indispensable pieces of equipment. The use of protective gloves is highly recommended. Back protection devices of the new generation provide the best passive prophylaxis for the pilot against pelvic and spinal cord injuries. This area hold the most promise for increasing safety and reducing risk of injury in future, apart from using beginners and intermediate wings. After acquisition of the pilot license performance and security training provide the best preparing to master unforeseeable situations.

Objective: Penetrating heart injury is potentially a life threatening condition due to cardiac tamponade or exsanguinating hemorrhage. The aim of this study was to evaluate victims who were referred to our hospital with penetrating heart and accompanying lung injuries and to review our overall outcome with this type of combined injuries. Methodology: Twenty patients with combined penetrating heart and lung injuries were operated at Yuzuncu Yil University Research Hospital, between May 1999 and January 2010. The diagnosis of combined heart and lung injuries was proved by surgical exploration in all cases. The surgical procedures mainly included the relief of cardiac tamponade, control of bleeding, repair of cardiac and pulmonary lacerations, and coronary artery bypass grafting if required. Results: In this series of 20 patients; there were 18 males and two females between the age of 14 to 60 years, with a mean age of 34.8+-13.5 years. Seventeen victims sustained stab wounds, and the remaining three were injured by a gunshot wounds. In 20 patients there were 22 cardiac chamber injuries. The most commonly injured cardiac chamber was the right ventricle followed by the left ventricle. In addition to the injuries to heart muscle, injuries to the coronary arteries were found in two patients. The most commonly injured lung lobe was the left upper lobe. Conclusion: Our experience shows that early diagnosis and immediate surgical intervention are the main factors affecting patient survival after penetrating heart and lung injuries. Therefore, heart injury should always be kept in mind in victims with penetrating thoracic injuries. (author)

The purpose of this study was to test the effect of specific diagnoses and surgical procedures on the likelihood of playing and length of career in the league by position. Cohort study; Level of evidence, 3. A database for all players reviewed at the annual National Football League Combine by the medical staff of 1 National Football League team from 1987 to 2000 was created, including each player's orthopaedic rating, diagnoses, surgical procedures, number of games played, and number of seasons played in the National Football League. Athletes were grouped by position as follows: offensive backfield, offensive receiver, offensive line, quarterback, tight end, defensive line, defensive secondary, linebacker, and kicker. The percentage of athletes who played in the National Football League was calculated by position for each specific diagnosis and surgery. The effect of injury on the likelihood of playing in the league varied by position. Anterior cruciate ligament injury significantly lowered the likelihood of playing in the league for defensive linemen (P = .03) and linebackers (P = .04). Meniscal injury significantly reduced the probability of playing (P history of spondylolysis had a significant effect for running backs (P = .01). Miscellaneous injuries (eg. acromioclavicular joint, knee medial collateral ligament, carpal fractures) had isolated position-specific effects. The significant injuries and diagnoses appear congruent with the position-specific demands placed on the athletes. This information is useful to physicians and athletic trainers caring for college football athletes as well as those assessing these athletes at the National Football League Combine.

Factors affecting occupational exposure to needlestick and sharps injuries among dentists in Taiwan: a nationwide survey.

Hsin-Chung Cheng

Full Text Available BACKGROUND: Although the risks of needlestick and sharps injuries (NSIs for dentists are well recognized, most papers published only described the frequency of occupational exposure to NSIs. Less has been reported assessing factors contributing to exposure to NSIs. The purpose of this study was to update the epidemiology of NSIs among dentists in Taiwan and identify factors affecting NSIs in order to find preventive strategies. METHODOLOGY/PRINCIPAL FINDINGS: A nationwide survey was conducted in dentists at 60 hospitals and 340 clinics in Taiwan. The survey included questions about factors supposedly affecting exposure to NSIs, such as dentist and facility characteristics, knowledge and attitudes about infectious diseases, and practices related to infection control. Univariate and multivariate logistic regression analyses were conducted to determine the association between risk factors and exposure to NSIs. In total, 434 (74.8% of 580 dentists returned the survey questionnaires, and 100 (23.0% reported that they had experienced more than one NSI per week. Our data showed that the risk of occupational NSIs is similarly heightened by an older age (odds ratio [OR], 3.18; 95% confidence interval [CI], 1.62-6.25, more years in practice (OR, 2.57; 95% CI, 1.41-4.69, working in clinics (OR, 1.73; 95% CI, 1.08-2.77, exhibiting less compliance with infection-control procedures (OR, 1.82; 95% CI, 1.04-3.18, having insufficient knowledge of blood-borne pathogens (OR, 1.67; 95% CI, 1.04-2.67, and being more worried about being infected by blood-borne pathogens (OR, 1.82; 95% CI, 1.05-3.13. CONCLUSIONS/SIGNIFICANCE: High rates of NSIs and low compliance with infection-control procedures highly contribute to the chance of acquiring a blood-borne pathogen infection and threaten occupational safety. This study reveals the possible affecting factors and helps in designing prevention strategies for occupational exposure to NSIs.

The Triaging and Treatment of Cold-Induced Injuries.

Science.gov (United States)

Sachs, Christoph; Lehnhardt, Marcus; Daigeler, Adrien; Goertz, Ole

2015-10-30

In Central Europe, cold-induced injuries are much less common than burns. In a burn center in western Germany, the mean ratio of these two types of injury over the past 10 years was 1 to 35. Because cold-induced injuries are so rare, physicians often do not know how to deal with them. This article is based on a review of publications (up to December 2014) retrieved by a selective search in PubMed using the terms "freezing," "frostbite injury," "non-freezing cold injury," and "frostbite review," as well as on the authors' clinical experience. Freezing and cold-induced trauma are part of the treatment spectrum in burn centers. The treatment of cold-induced injuries is not standardized and is based largely on case reports and observations of use. distinction is drawn between non-freezing injuries, in which there is a slow temperature drop in tissue without freezing, and freezing injuries in which ice crystals form in tissue. In all cases of cold-induced injury, the patient should be slowly warmed to 22°-27°C to prevent reperfusion injury. Freezing injuries are treated with warming of the body's core temperature and with the bathing of the affected body parts in warm water with added antiseptic agents. Any large or open vesicles that are already apparent should be debrided. To inhibit prostaglandin-mediated thrombosis, ibuprofen is given (12 mg/kg body weight b.i.d.). The treatment of cold-induced injuries is based on their type, severity, and timing. The recommendations above are grade C recommendations. The current approach to reperfusion has yielded promising initial results and should be further investigated in prospective studies.

Apoptosis-induced lymphopenia in sepsis and other severe injuries.

Girardot, Thibaut; Rimmelé, Thomas; Venet, Fabienne; Monneret, Guillaume

2017-02-01

Sepsis and other acute injuries such as severe trauma, extensive burns, or major surgeries, are usually followed by a period of marked immunosuppression. In particular, while lymphocytes play a pivotal role in immune response, their functions and numbers are profoundly altered after severe injuries. Apoptosis plays a central role in this process by affecting immune response at various levels. Indeed, apoptosis-induced lymphopenia duration and depth have been associated with higher risk of infection and mortality in various clinical settings. Therapies modulating apoptosis represent an interesting approach to restore immune competence after acute injury, although their use in clinical practice still presents several limitations. After briefly describing the apoptosis process in physiology and during severe injuries, we will explore the immunological consequences of injury-induced lymphocyte apoptosis, and describe associations with clinically relevant outcomes in patients. Therapeutic perspectives targeting apoptosis will also be discussed.

Nanomedicine strategies for treatment of secondary spinal cord injury

The secondary injury results from the biological cascade after the primary injury and affects previous uninjured, healthy tissue. Therefore, the mitigation of such a cascade would benefit patients suffering a primary injury and allow the body to recover more quickly. Unfortunately, the delivery of effective therapeutics is quite limited. Due to the inefficient delivery of therapeutic drugs, nanoparticles have become a major field of exploration for medical applications. Based on their material properties, they can help treat disease by delivering drugs to specific tissues, enhancing detection methods, or a mixture of both. Incorporating nanomedicine into the treatment of neuronal injury and disease would likely push nanomedicine into a new light. This review highlights the various pathological issues involved in secondary spinal cord injury, current treatment options, and the improvements that could be made using a nanomedical approach.

Highlights: • Purely intra-epiphyseal stress injuries of the proximal tibial epiphysis are described for the first time. • The variation in the MRI findings of these injuries depending on the stage of maturation is demonstrated. • We postulate a patho-mechanism to explain the variations in site and appearance of stress injuries in this region. - Abstract: Stress induced injuries affecting the physeal plate or cortical bone in children and adolescents, especially young athletes, have been well described. However, there are no reports in the current English language literature of stress injury affecting the incompletely ossified epiphyseal cartilage. We present four cases of stress related change to the proximal tibial epiphysis (PTE) along with their respective magnetic resonance imaging (MRI) appearances ranging from subtle oedema signal to a pseudo-tumour like appearance within the epiphyseal cartilage. The site and pattern of intra-epiphyseal injury is determined by the type of tissue that is affected, the maturity of the skeleton and the type of forces that are transmitted through the tissue. We demonstrate how an awareness of the morphological spectrum of MRI appearances in intra-epiphyseal stress injury and the ability to identify concomitant signs of stress in other nearby structures can help reduce misdiagnosis, avoid invasive diagnostic procedures like bone biopsy and reassure patients and their families.

Highlights: • Purely intra-epiphyseal stress injuries of the proximal tibial epiphysis are described for the first time. • The variation in the MRI findings of these injuries depending on the stage of maturation is demonstrated. • We postulate a patho-mechanism to explain the variations in site and appearance of stress injuries in this region. - Abstract: Stress induced injuries affecting the physeal plate or cortical bone in children and adolescents, especially young athletes, have been well described. However, there are no reports in the current English language literature of stress injury affecting the incompletely ossified epiphyseal cartilage. We present four cases of stress related change to the proximal tibial epiphysis (PTE) along with their respective magnetic resonance imaging (MRI) appearances ranging from subtle oedema signal to a pseudo-tumour like appearance within the epiphyseal cartilage. The site and pattern of intra-epiphyseal injury is determined by the type of tissue that is affected, the maturity of the skeleton and the type of forces that are transmitted through the tissue. We demonstrate how an awareness of the morphological spectrum of MRI appearances in intra-epiphyseal stress injury and the ability to identify concomitant signs of stress in other nearby structures can help reduce misdiagnosis, avoid invasive diagnostic procedures like bone biopsy and reassure patients and their families

To study the relationship between severity of injury of the lower limb and severity of injury of the head, thoracic, and abdominal regions in frontal-impact road traffic collisions. Consecutive hospitalised trauma patients who were involved in a frontal road traffic collision were prospectively studied over 18 months. Patients with at least one Abbreviated Injury Scale (AIS) ≥3 or AIS 2 injuries within two AIS body regions were included. Patients were divided into two groups depending on the severity of injury to the head, chest or abdomen. Low severity group had an AIS chest or abdominal injuries. Eighty-five patients were studied. The backward likelihood logistic regression model defining independent factors affecting severity of head injuries was highly significant (p =0.01, nagelkerke r square = 0.1) severity of lower limb injuries was the only significant factor (p=0.013) having a negative correlation with head injury (Odds ratio of 0.64 (95% CI: 0.45-0.91). Occupants who sustain a greater severity of injury to the lower limb in a frontal-impact collision are likely to be spared from a greater severity of head injury.

Femoral vessel injury by a nonlethal weapon projectile

Directory of Open Access Journals (Sweden)

Rodrigo Bruno Biagioni, MD

2018-06-01

Full Text Available Rubber projectiles are used as an alternative to metal bullets owing to their lower morbidity and mortality rate. There are few reports of vascular lesions of extremities caused by rubber projectiles in the literature. The authors report the case of a 37-year-old man who was the victim of a penetrating injury to the left thigh with a rubber projectile. He reported only pain at the site of the injury; pulses were decreased in the affected limb. After arteriography confirmed an injury to the superficial femoral artery, he underwent an arterial and venous femorofemoral bypass using a reversed contralateral saphenous vein.

Despite the lethality of injuries to the heart, optimizing factors that impact mortality for victims that do survive to reach the hospital is critical. From 2003 to 2012, prehospital data, injury characteristics, and clinical patient factors were analyzed for victims with penetrating cardiac injuries (PCIs) at an urban, level I trauma center. Over the 10-year study, 80 PCI patients survived to reach the hospital. Of the 21 factors analyzed, prehospital cardiopulmonary resuscitation (odds ratio [OR] = 30), scene time greater than 10 minutes (OR = 58), resuscitative thoracotomy (OR = 19), and massive left hemothorax (OR = 15) had the greatest impact on mortality. Cardiac tamponade physiology demonstrated a "protective" effect for survivors to the hospital (OR = .08). Trauma surgeons can improve mortality after PCI by minimizing time to the operating room for early control of hemorrhage. In PCI patients, tamponade may provide a physiologic advantage (lower mortality) compared to exsanguination. Copyright © 2016 Elsevier Inc. All rights reserved.

Plantar fascia and distal Achilles injuries are common in elite athletes. Acute athletic injuries of the plantar fascia include acute plantar fasciopathy and partial or complete tears. Underlying most acute injuries is a background of underlying chronic plantar fasciopathy. Injuries may affect the central or less commonly lateral portions of the fascia and acute tears are generally proximal. Athletic Achilles injuries may occur at the mid tendon or the distal insertion, and there may be an underlying chronic tendinopathy. Acute or chronic paratendinopathy may occur as a separate entity or combined with Achilles injury. In this article, the spectrum of athletic injuries of the plantar fascia and Achilles is described, illustrated by imaging findings from the London 2012 Olympic games.

Illness and aging both cause many structural and functional alterations in the human body, rendering elderly people liable to overloading of the musculoskeletal and cardiovascular systems. It should, however, be kept in mind that immobilisation and inactivity have even more deleterious effects on structures and functions in the elderly than in younger adults. Most physically active elderly people are selected individuals with respect to their superior health and physical capacity compared with inactive persons of the same age, thus making it possible to further improve their physical capacity. They will, however, be affected by some of the drawbacks of physical overloading, mostly due to the diminished ability of aging body systems to adapt to high levels of loading. The safety margin of an exercise dose tends to decline with aging. Exertional injuries are common among the elderly, and are connected mostly with degenerative aging processes. Acute injuries are common in those elderly people participating in sport activities which demand high coordination, reaction time, and balance capabilities, such as ball games, down-hill skiing, and gymnastics. Muscle has been reported to be the most commonly acutely injured tissue among active elderly athletes. The lower extremities are the most susceptible to injury. A large proportion of injuries (acute and exertional) are mild and can be treated by brief cessation of training and competition activities. Some of the injuries are, however, long term and cause disability not only during training and competition, but also in the normal activities of daily living. It is important that these injuries are treated as soon as possible and in the most effective way, similarly to injuries suffered by younger people. In treating elderly people, it is most important to avoid the detrimental effects of immobilisation; this requires active treatment and rehabilitation with compensatory exercise therapy.

2017-01-01

With the objective of analyzing fatal and non-fatal road traffic injuries in cyclists and to document helmet use in this road user to inform sustainable mobility policies, a descriptive analysis of four secondary official information sources was conducted at the national level: mortality, Ministry of Health's hospital discharges, Unintentional and Violence Registry System (SIS-SS-17-P) and the 2012 National Health and Nutrition Survey (ENSANUT). Only SIS-SS-17-P and ENSANUT document helmet use. Except for ENSANUT information analyzed is of 2014.A total of 190 cyclists died in Mexico during 2014 and 392 were hospitalized; head was the anatomical region most frequently affected (63% and 32%, respectively). Only 0.75% of the 667 cases registered in SIS-17 reported helmet use and 24% suffered head injuries. Of the 165,348 non-fatally injured cyclists from ENSANUT <10% used helmet, 24% had head injuries and more than 16,000 suffered permanent injuries. Whereas cyclist-friendly infrastructure is an effective intervention to prevent injuries in the long term, helmet use could potentially reduce the frequency and severity of head injuries in the short run while bicycle use widespread as a means of transportation providing "safety in numbers".

This study analyzed the incidence and characteristics of injuries sustained by amateur youth football players in Portugal during season 2015 - 2016. This is an observational descriptive study. We analyzed Portuguese youth football players' injuries over six months of a season. A total of 529 players were divided according to their age in two groups (Under-17 and Under-19). Data on injuries were collected. Throughout all 62 062.0 hours of exposure recorded, 248 injuries were reported in 173 different players. The average incidence of injury was 3.87 (95% CI = 2.81; 4.94) per 1000 hours of football exposure. There was a significantly higher average incidence of injury during matches - 14.22 (95% CI = 10.35; 18.09) per 1000 hours of exposure - when compared to the average incidence of injury during training - 2.06 (95% CI = 1.22; 2.90) per 1000 hours of exposure. This significance was also observed when the comparison was made within each age group. A traumatic mechanism was involved in 76.6% of all the injuries, while overuse was reported in 12.9%. The most common type was the injury that affected muscles and tendons (52.8%). The body location most commonly affected by injuries was the thigh (24.6%). Even though is essential a better characterization of Portuguese athletes of younger age groups such as those discussed in this study, the results of the studied population are in agreement with the existing literature. However, this study provides more information that may be important to better target the Portuguese athletes' training for injury prevention. This study provides descriptive data on injuries developed in a subpopulation of Portuguese amateur youth football players that could represent a focus for future prevention.

Resisting rape: the effects of victim self-protection on rape completion and injury.

Science.gov (United States)

Tark, Jongyeon; Kleck, Gary

2014-03-01

The impact of victim resistance on rape completion and injury was examined utilizing a large probability sample of sexual assault incidents, derived from the National Crime Victimization Survey (1992-2002), and taking into account whether harm to the victim followed or preceded self-protection (SP) actions. Additional injuries besides rape, particularly serious injuries, following victim resistance are rare. Results indicate that most SP actions, both forceful and nonforceful, reduce the risk of rape completion, and do not significantly affect the risk of additional injury.

Nerve injury caused by mandibular block analgesia

DEFF Research Database (Denmark)

Hillerup, S; Jensen, Rigmor H

2006-01-01

Fifty-four injection injuries in 52 patients were caused by mandibular block analgesia affecting the lingual nerve (n=42) and/or the inferior alveolar nerve (n=12). All patients were examined with a standardized test of neurosensory functions. The perception of the following stimuli was assessed......: feather light touch, pinprick, sharp/dull discrimination, warm, cold, point location, brush stroke direction, 2-point discrimination and pain perception. Gustation was tested for recognition of sweet, salt, sour and bitter. Mandibular block analgesia causes lingual nerve injury more frequently than...... inferior alveolar nerve injury. All grades of loss of neurosensory and gustatory functions were found, and a range of persisting neurogenic malfunctions was reported. Subjective complaints and neurosensory function tests indicate that lingual nerve lesions are more incapacitating than inferior alveolar...

Reconstruction of facial nerve injuries in children.

Fattah, Adel; Borschel, Gregory H; Zuker, Ron M

2011-05-01

Facial nerve trauma is uncommon in children, and many spontaneously recover some function; nonetheless, loss of facial nerve activity leads to functional impairment of ocular and oral sphincters and nasal orifice. In many cases, the impediment posed by facial asymmetry and reduced mimetic function more significantly affects the child's psychosocial interactions. As such, reconstruction of the facial nerve affords great benefits in quality of life. The therapeutic strategy is dependent on numerous factors, including the cause of facial nerve injury, the deficit, the prognosis for recovery, and the time elapsed since the injury. The options for treatment include a diverse range of surgical techniques including static lifts and slings, nerve repairs, nerve grafts and nerve transfers, regional, and microvascular free muscle transfer. We review our strategies for addressing facial nerve injuries in children.

Craniomaxillofacial falling bullet injuries and management.

Shuker, Sabri T; Sadda, Raid

2010-07-01

The purpose of this study was to bring attention to craniocerebral maxillofacial perforating/penetrating injuries due to AK-47 Kalashnikov falling bullets (FBs); these dangerous injuries to both civilians and soldiers are rare. A review of the literature shows no reports on AK-47 FBs leading to double craniocerebral perforation and settling into the maxillofacial region. The number of victims, the AK-47's availability, the associated morbidity and mortality rates, and the rarity of cases prompted this article. The treatment of injuries to the craniocerebral facial clinical profile due to FBs is challenging, and an understanding of the neurosurgical and maxillofacial management of these low-velocity FB injuries is required. We treated 11 cases due to AK-47 rifle FBs and 1 due to anti-aircraft Dashka 12.7-mm FBs. Craniocerebral facial injuries were treated and lodged bullets removed from different challenging locations in the base of the skull, without increasing morbidity and with avoidance of unnecessary surgical trauma to the affected area by the bullets. The required identification of such injuries can be difficult, and the removal of the lodged bullet to prevent secondary complications and reduce the chance of secondary infection can be graver than in other parts of the body. AK-47 FBs are a major public health concern internationally and require serious attention in terms of protection and management for civilians and soldiers in uniform.

2017-03-01

In sports-related muscle injuries, the main goal of the sports medicine physician is to return the athlete to competition-balanced against the need to prevent the injury from worsening or recurring. Prognosis based on the available clinical and imaging information is crucial. Imaging is crucial to confirm and assess the extent of sports-related muscle injuries and may help to guide management, which directly affects the prognosis. This is especially important when the diagnosis or grade of injury is unclear, when recovery is taking longer than expected, and when interventional or surgical management may be necessary. Several imaging techniques are widely available, with ultrasonography and magnetic resonance imaging currently the most frequently applied in sports medicine. This state of the art review will discuss the main imaging modalities for the assessment of sports-related muscle injuries, including advanced imaging techniques, with the focus on the clinical relevance of imaging features of muscle injuries. © RSNA, 2017 Online supplemental material is available for this article.

Strauss, Samuel; Krog, Ralph L.; Feiveson, Alan H.

2005-01-01

BACKGROUND: Astronaut spacewalk training can result in a variety of symptom complaints and possible injuries. This study quantified and characterized signs, symptoms, and injuries resulting from extravehicular activity spacesuit training at NASA's Neutral Buoyancy Laboratory, Johnson Space Center, Houston, TX, immersion facility. METHODS: We identified the frequency and incidence of symptoms by location, mechanisms of injury, and effective countermeasures. Recommendations were made to improve injury prevention, astronaut training, test preparation, and training hardware. At the end of each test, a questionnaire was completed documenting signs and symptoms, mechanisms of injury, and countermeasures. RESULTS: Of the 770 tests, there were 190 in which suit symptoms were reported (24.6%). There were a total of 352 reported suit symptom comments. Of those symptoms, 166 were in the hands (47.16%), 73 were in the shoulders (20.7%), and 40 were in the feet (11.4%). Others ranged from 6.0% to 0.28%, respectively, from the legs, arms, neck, trunk, groin, and head. Causal mechanisms for the hands included moisture and hard glove contacts resulting in fingernail injuries; in the shoulders, hard contact with suit components and strain mechanisms; and in the feet, hard boot contact. The severity of symptoms was highest in the shoulders, hands, and feet. CONCLUSIONS: Most signs and symptoms were mild, self-limited, of brief duration, and were well controlled by available countermeasures. Some represented the potential for significant injury with consequences affecting astronaut health and performance. Correction of extravehicular activity training-related injuries requires a multidisciplinary approach to improve prevention, medical intervention, astronaut training, test planning, and suit engineering.

Parkour sport is the playfully breaching of obstacles originally not created to get from A to B in the fastest manner. There have been only few publications on injuries in this young and trendy sport mainly performed in urban areas. The aim of this study is to analyse parkour-related acute injuries and their factors. For the retrospective cross-sectional study, a total of n = 266 traceurs (m: n = 255, w: n = 11) completed anonymized online questionnaires. On average, each traceur sustained 1.9 injuries per sport career/year, or 5.5 injuries/1000 h training, respectively. The upper extremity was the most affected body region (58 %), followed by the lower extremity (27 %), head and the back. An increase of injuries from proximal to distal was observed in the upper extremity. However, for the lower extremity it was the opposite. Of all injuries, the most common were skin abrasions (70.3 %). Muscle injuries were observed in 13.1 % of the traceurs, followed by dislocations (6.1 %), and soft tissue (e. g., ligaments, tendons) injuries (5.3 %). Passive precautionary measures were abandoned by the majority of the traceurs (88 %). Landing belonged to the movement elements resulting in most of the injuries (61 %), followed by supportive and static efforts of the arms (10.7 %). Overestimation (23 %) as well as misjudging the situation (20 %) were the most common causes. Other than expected, parkour is an urban movement style with most of the injuries being neither severe nor common despite the lack of precautionary measures. Localisation and type of injuries reflect the characteristic movement elements. There is a need for further investigations to allow a more differentiated analysis in order to develop injury prevention concepts. © Georg Thieme Verlag KG Stuttgart · New York.

In industrializing countries, occupational safety and health have been affected by globalization. However, a lack of reliable data prevents evaluation of this situation. Therefore, we examined industrial distributions and risks of severe occupational injuries among workers in Thailand, which is one of the few industrializing countries that compiles nationwide data. Data on workers who made claims for occupational injuries from 2007 to 2009 were extracted from the Workmen's Compensation Fund records in Thailand. Among 501,334 claimants, we evaluated the industrial distributions of severe occupational injuries (i.e., permanent disability and death). We then examined the associations between industry and those injuries, using proportionate ratios (PRs) between each industrial category and the overall distribution of occupational injuries. The number of workers in manufacturing making claims for severe occupational injuries was the largest among all industrial categories (319,114/501,334 injuries), although the total number of occupational injuries recently declined. Additionally, workers in manufacturing experienced severe occupational injuries more often compared with the overall distribution of occupational injuries. The PRs (95% confidence interval) for manufacturing were 1.17 (1.14-1.20) in men and 1.33 (1.27-1.38) in women. After adjusting for individual characteristics, the results did not substantially change. Manufacturing seems to have the largest burden of occupational injuries in industrializing countries like Thailand.

To describe the epidemiology of emergency department (ED) visits for trampoline-related injuries among U.S. children from January 1, 2000, to December 31, 2005, using the National Electronic Injury Surveillance System (NEISS) and to compare recent trampoline injury demographics and injury characteristics with those previously published for 1990-1995 using the same data source. A stratified probability sample of U.S. hospitals providing emergency services in NEISS was utilized for 2000-2005. Nonfatal trampoline-related injury visits to the ED were analyzed for patients from 0 to 18 years of age. In 2000-2005, there was a mean of 88,563 ED visits per year for trampoline-related injuries among 0-18-year-olds, 95% of which occurred at home. This represents a significantly increased number of visits compared with 1990-1995, when there was an average of 41,600 visits per year. Primary diagnosis and principal body part affected remained similar between the two study periods. ED visits for trampoline-related injuries in 2000-2005 increased in frequency by 113% over the number of visits for 1990-1995. Trampoline use at home continues to be a significant source of childhood injury morbidity.

Radioprotectors effect on the efficiency of combined treatment of radiation injuries (review of the literature)

International Nuclear Information System (INIS)

Farshatov, M.N.

1986-01-01

Therapeutic efficiency of radioprotector action (cystamine, in particular) under isolated and combined (in combination with burns, mechanical injuries of skull, brain, limbs internal organs etc.) radiation affection is discussed on the basis of experiment data, obtained by different authors. The conclusion is drawn, that under combined radiation affections with leading radial component, radioprotectors provide for approximately the same protection effect as under isolated radioactive irradiation by a corresponding dose. In combination with radial and nonradial injury means they can sufficiently reduce lethality and create better conditions for favourable course of burn deseases and mechanical injuries. It is pointed out, that preliminary protection gains decisive value in cases, when under combined radiation affection the radial component prevails. In this case radiosensitive tissue protection becomes necessary condition for the victim's life preservation, complication frequency reduction and improvement of treatment results. Advisability of inclusion of medical protection means into the step-by-step treatment system, wile foreseeing both isolated and combined radiation affections, is shown

The Evidence for Brain Injury in Whiplash Injuries

Directory of Open Access Journals (Sweden)

Michael P. Alexander

2003-01-01

Full Text Available The evidence that brain damage can occur in injuries that produce whiplash is reviewed. The clinical phenomena for the two injuries are the same. Pure whiplash injury implies no, or minimal head contact, but many patients also have head contact against a head rest or the steering wheel or windshield. The relative severity of the neck injury and the head injury distinguishes whiplash from mild closed head injury. If there is brain injury is some patients with whiplash, it, by definition, falls at the mildest end of the concussion spectrum. The relationship between these two injuries is examined.

The impact of the business cycle on occupational injuries in the UK.

Science.gov (United States)

Davies, Rhys; Jones, Paul; Nuñez, Imanol

2009-07-01

This paper investigates the cyclical fluctuations in rates of workplace injury for the UK from 1986 to 2005. Time series analysis shows that, in aggregate terms, the rate of minor injuries is pro-cyclical whilst the rate of major injury is not affected by the level of economic activity. Analysis by sector reveals that cyclical fluctuations are sharper in the construction and manufacturing sectors. Using panel data, we find that fluctuations in both the rates of minor and major injury are related to the level of new hiring and the ratio of actual to usual hours worked. However, only minor injuries are related to variables that control for workers' bargaining power. The analysis demonstrates the importance of both compositional effects and individual reporting behaviour to understanding cyclical variations in workplace injury rates.

Children and youth with 'unspecified injury to the head': implications for traumatic brain injury research and surveillance.

The case definition for traumatic brain injury (TBI) often includes 'unspecified injury to the head' diagnostic codes. However, research has shown that the inclusion of these codes leads to false positives. As such, it is important to determine the degree to which inclusion of these codes affect the overall numbers and profiles of the TBI population. The objective of this paper was to profile and compare the demographic and clinical characteristics, intention and mechanism of injury, and discharge disposition of hospitalized children and youth aged 19 years and under using (1) an inclusive TBI case definition that included 'unspecified injury to the head' diagnostic codes, (2) a restricted TBI case definition that excluded 'unspecified injury to the head 'diagnostic codes, and (3) the 'unspecified injury to the head' only case definition. The National Ambulatory Care Reporting System and the Discharge Abstract Database from Ontario, Canada, were used to identify cases between fiscal years 2003/04 and 2009/10. The rate of TBI episodes of care using the inclusive case definition for TBI (2,667.2 per 100,000) was 1.65 times higher than that of the restricted case definition (1,613.3 per 100,000). 'Unspecified injury to the head' diagnostic codes made up of 39.5 % of all cases identified with the inclusive case definition. Exclusion of 'unspecified injury to the head' diagnostic code in the TBI case definition resulted in a significantly higher proportion of patients in the intensive care units (p definition of TBI for the children and youth population is important, as it has implications for the numbers used for policy, resource allocation, prevention, and planning of healthcare services. This paper can inform future work on reaching consensus on the diagnostic codes for defining TBI in children and youth.

Predictors of work injury in underground mines - an application of a logistic regression model

2009-05-15

Mine accidents and injuries are complex and generally characterized by several factors starting from personal to technical, and technical to social characteristics. In this study, an attempt has been made to identify the various factors responsible for work related injuries in mines and to estimate the risk of work injury to mine workers. The prediction of work injury in mines was done by a step-by-step multivariate logistic regression modeling with an application to case study mines in India. In total, 18 variables were considered in this study. Most of the variables are not directly quantifiable. Instruments were developed to quantify them through a questionnaire type survey. Underground mine workers were randomly selected for the survey. Responses from 300 participants were used for the analysis. Four variables, age, negative affectivity, job dissatisfaction, and physical hazards bear significant discriminating power for risk of injury to the workers, comparing between cases and controls in a multivariate situation while controlling all the personal and socio-technical variables. The analysis reveals that negatively affected workers are 2.54 times more prone to injuries than the less negatively affected workers and this factor is a more important risk factor for the case-study mines. Long term planning through identification of the negative individuals, proper counseling regarding the adverse effects of negative behaviors and special training is urgently required. Care should be taken for the aged and experienced workers in terms of their job responsibility and training requirements. Management should provide a friendly atmosphere during work to increase the confidence of the injury prone miners. 44 refs., 4 tabs.

Detailed knowledge on injury characteristics from different medical settings is essential to improve the development of injury prevention strategies in different team sports.  Team sport injuries were retrospectively analysed in a Level I trauma department registry over 15 years. Injury and treatment data were compared with regard to competition and training exposure. Injury data such as "time of visitation", "type of injury", "multiple injured body regions" and "immediate hospitalisation" helped to define the severity level of each team sports injury.  At the Level I trauma department, 11.361 sports-related injuries were seen over 15 years, of which 34.0 % were sustained during team sports. Soccer injuries were the most common injuries of all team sports (71.4 %). The lower extremity was the most affected body region overall, followed by the upper extremity. Head injuries were mainly seen in Ice hockey and American football and concussion additionally frequently in team handball. Slight injuries like sprains or contusions occurred most frequently in all team sports. In soccer and team handball, injuries sustained in competition were significantly more severe (p team sports, injury prevention strategies should address competitive as well as training situations, whichmay need different strategies. © Georg Thieme Verlag KG Stuttgart · New York.

The purpose of this study is to investigate the effect of risk factors including International Normalized Ratio (INR) as well as the Partial Thromboplastin Time (PTT) scores on several outcomes, including hospital length of stay (LOS) and The Extended Glasgow Outcome Scale (GOSE) following TBI in the elderly population. Data were retrospectively collected on patients (n=982) aged 65 and above who were admitted post TBI to the McGill University Health Centre-Montreal General Hospital from 2000 to 2011. Age, Injury Severity Score (ISS), Glasgow Coma Scale score (GCS), type of trauma (isolated TBI vs polytrauma including TBI), initial CT scan results according to the Marshall Classification and the INR and PTT scores and prescriptions of antiplatelet or anticoagulant agents (AP/AC) were collected. Results also indicated that age, ISS and GSC score have an effect on the GOSE score. We also found that taking AC/AP has an effect on GOSE outcome, but that this effects depends on PTT, with lower odds of a worse outcome for those taking AC/AP agents as the PTT value goes up. However, this effect only becomes significant as the PTT value reaches 60 and above. Age and injury severity rather than antithrombotic agent intake are associated with adverse acute outcome such as GOSE in hospitalized elderly TBI patients. Copyright © 2017 Elsevier Ltd.

Khuu, Steven; Musalem, Lindsay L; Beach, Tyson A C

2015-10-01

Biomechanical quantities acquired during the drop vertical jump (DVJ) are used in the assessment of athletic performance and injury risk. The objective was to examine the impact of different verbal instructions on spatiotemporal, kinematic, and kinetic variables commonly included in such assessments. Ten men and 10 women from local varsity and club volleyball, basketball, figure skating, and track and field teams volunteered to participate. The athletes performed DVJs after given instructions to minimize ground contact time (CT), maximize jump height (HT), and synchronously extend the lower extremity joints (EX). Between the CT, HT, and EX conditions, body segment and joint angles were compared together with characteristics of vertical ground reaction force (GRF), whole-body power output, stiffness, and center-of-mass displacement time histories. Verbal instructions were found to influence nearly all of the spatiotemporal, body segment and joint kinematic, and kinetic variables that were statistically analyzed. Particularly noteworthy was the finding that athletic performance indices (e.g., jump height, power output, vertical stiffness, and reactive strength index) and lower extremity injury risk markers (e.g., peak vertical GRF and frontal plane knee angle) were significantly different (p ≤ 0.05) between the CT, HT, and EX conditions. The findings of this study suggest that verbal instructions should be controlled and/or clearly documented when using the DVJ to assess athletic performance potential and injury risk. Moreover, practitioners who devise performance enhancement and injury prevention strategies based on DVJ assessments are advised to consider that "coaching" or "cueing" during the task execution could impact conclusions drawn.

Investigation of the role of personal factors on work injury in underground mines using structural equation modeling

Work injuries in mines are complex and generally characterized by several factors starting from personal to technical and technical to social characteristics. In this paper, investigation was made through the application of structural equation modeling to study the nature of relationships between the influencing/associating personal factors and work injury and their sequential relationships leading towards work injury occurrences in underground coal mines. Six variables namely, rebelliousness, negative affectivity, job boredom, job dissatisfaction and work injury were considered in this study. Instruments were developed to quantify them through a questionnaire survey. Underground mine work-ers were randomly selected for the survey. Responses from 300 participants were used for the analysis. The structural model of LISREL was used to estimate the interrelationships amongst the variables. The case study results show that negative affectivity and job boredom induce more job dissatisfaction to the workers whereas risk taking attitude of the individual is positively influenced by job dissatisfaction as well as by rebelliousness characteristics of the individual. Finally, risk taking and job dissatisfaction are having positive significant direct relationship with work injury. The findings of this study clearly reveal that rebelliousness, negative affectivity and job boredom are the three key personal factors influencing work related injuries in mines that need to be addressed properly through effective safety programs.

Home health aides (HHAs) work in a high-risk industry and experience high rates of work-related injury that have been significantly associated with reduction in workers and organisational productivity, quality and performance. The main objective of the study was to examine how worker environment and ergonomic factors affect HHA risk for reporting occupational injuries. We used cross-sectional analysis of data from the 2007 National Home Health and Hospice Aide Survey (NHHAS). The study sample consisted of a nationally represented sample of home health aides (n=3.377) with a 76.6% response rate. We used two scales 1 : a Work Environment Scale and 2 an Ergonomic Scale. Univariate and bivariate analyses were conducted to describe HHA work-related injury across individual, job and organisational factors. To measure scale reliability, Cronbach's alphas were calculated. Multivariable logistic regression was used to determine predictors of reported occupational injury. In terms of Work Environment Scale, the injury risk was decreased in HHAs who did not consistently care for the same patients (OR=0.96, 95% CI: 0.53 to 1.73). In terms of Ergonomic Scale, the injury risk was decreased only in HHAs who reported not needing any other devices for job safety (OR=0.30, 95% (CI): 0.15 to 0.61). No other Work Environment or Ergonomic Scale factors were associated with HHAs' risk of injury. This study has great implications on a subcategory of the workforce that has a limited amount of published work and studies, as of today, as well as an anticipated large demand for them. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

2011-01-01

Background Chest injuries constitute a continuing challenge to the trauma or general surgeon practicing in developing countries. This study was conducted to outline the etiological spectrum, injury patterns and short term outcome of these injuries in our setting. Patients and methods This was a prospective study involving chest injury patients admitted to Bugando Medical Centre over a six-month period from November 2009 to April 2010 inclusive. Results A total of 150 chest injury patients were studied. Males outnumbered females by a ratio of 3.8:1. Their ages ranged from 1 to 80 years (mean = 32.17 years). The majority of patients (72.7%) sustained blunt injuries. Road traffic crush was the most common cause of injuries affecting 50.7% of patients. Chest wall wounds, hemothorax and rib fractures were the most common type of injuries accounting for 30.0%, 21.3% and 20.7% respectively. Associated injuries were noted in 56.0% of patients and head/neck (33.3%) and musculoskeletal regions (26.7%) were commonly affected. The majority of patients (55.3%) were treated successfully with non-operative approach. Underwater seal drainage was performed in 39 patients (19.3%). One patient (0.7%) underwent thoracotomy due to hemopericardium. Thirty nine patients (26.0%) had complications of which wound sepsis (14.7%) and complications of long bone fractures (12.0%) were the most common complications. The mean LOS was 13.17 days and mortality rate was 3.3%. Using multivariate logistic regression analysis, associated injuries, the type of injury, trauma scores (ISS, RTS and PTS) were found to be significant predictors of the LOS (P trauma scores (ISS, RTS and PTS), the need for ICU admission and the presence of complications (P Chest injuries resulting from RTCs remain a major public health problem in this part of Tanzania. Urgent preventive measures targeting at reducing the occurrence of RTCs is necessary to reduce the incidence of chest injuries in this region. PMID:21244706

2017-01-01

Acromioclavicular joint (ACJ) injuries are common, but their incidence is probably underestimated. As the treatment of some sub-types is still debated, we reviewed the available literature to obtain an overview of current management. We analysed the literature using the PubMed search engine. There is consensus on the treatment of Rockwood type I and type II lesions and for high-grade injuries of types IV, V and VI. The treatment of type III injuries remains controversial, as none of the studies has proven a significant benefit of one procedure when compared with another. Several approaches can be considered in reaching a valid solution for treating ACJ lesions. The final outcome is affected by both vertical and horizontal post-operative ACJ stability. Synthetic devices, positioned using early open or arthroscopic procedures, are the main choice for young people. Type III injuries should be managed surgically only in cases with high-demand sporting or working activities. Cite this article: EFORT Open Rev 2017;2:432–437. DOI: 10.1302/2058-5241.2.160085.

How children with head injury represent real and deceptive emotion in short narratives.

Science.gov (United States)

Dennis, M; Barnes, M A; Wilkinson, M; Humphreys, R P

1998-02-15

Narratives are not only about events, but also about the emotions those events elicit. Understanding a narrative involves not just the affective valence of implied emotional states, but the formation of an explicit mental representation of those states. In turn, this representation provides a mechanism that particularizes emotion and modulates its display, which then allows emotional expression to be modified according to particular contexts. This includes understanding that a character may feel an emotion but inhibit its display or even express a deceptive emotion. We studied how 59 school-aged children with head injury and 87 normally-developing age-matched controls understand real and deceptive emotions in brief narratives. Children with head injury showed less sensitivity than controls to how emotions are expressed in narratives. While they understood the real emotions in the text, and could recall what provoked the emotion and the reason for concealing it, they were less able than controls to identify deceptive emotions. Within the head injury group, factors such as an earlier age at head injury and frontal lobe contusions were associated with poor understanding of deceptive emotions. The results are discussed in terms of the distinction between emotions as felt and emotions as a cognitive framework for understanding other people's actions and mental states. We conclude that children with head injury understand emotional communication, the spontaneous externalization of real affect, but not emotive communication, the conscious, strategic modification of affective signals to influence others through deceptive facial expressions.

Studies have reported associations between obesity and injury in a single occupation or industry. Our study estimated the prevalence of work-site injuries and investigated the association between obesity and work-site injury in a nationally representative sample of U.S. workers. Self-reported weight, height, and injuries within the previous three months were collected annually for U.S. workers in the National Health Interview Survey (NHIS) from 2004-2012. Participants were categorized as normal weight (BMI: 18.5-24.9kg/m(2)), overweight (BMI: 25.0-29.9), obese I (BMI: 30.0-34.9), and obese II (BMI: 35+). The prevalence of injury and prevalence ratios from fitted logistic regression models was used to assess relationships between obesity and injury after adjusting for covariates. Sampling weights were incorporated using SUDAAN software. During the 9-year study period from 2004 to 2012, 1120 workers (78 workers per 10,000) experienced a work-related injury during the previous three months. The anatomical sites with the highest prevalence of injury were the back (14.3/10,000±1.2), fingers (11.5±1.3), and knees (7.1±0.8). The most common types of injuries were sprains/strains/twists (41.5% of all injuries), cuts (20.0%), and fractures (11.8%). Compared to normal weight workers, overweight and obese workers were more likely to experience work-site injuries [overweight: PR=1.25 (95% CI=1.04-1.52); obese I: 1.41 (1.14-1.74); obese II: 1.68 (1.32-2.14)]. These injuries were more likely to affect the lower extremities [overweight: PR=1.48, (95% CI=1.03-2.13); obese I: 1.70 (1.13-2.55); obese II: 2.91 (1.91-4.41)] and were more likely to be due to sprains/strains/twists [overweight: PR=1.73 (95% CI=1.29-2.31); obese I: PR=2.24 (1.64-3.06); obese II: PR=2.95 (2.04-4.26)]. Among NHIS participants, overweight and obese workers were 25% to 68% more likely to experience injuries than normal weight workers. Weight reduction policies and management programs may be effectively

Participation in high school sports has grown 16.1% over the last decade, but few studies have compared the overall injury risks in girls' softball and boys' baseball. To examine the incidence of injury in high school softball and baseball players. Cohort study. Greenville, South Carolina, high schools. Softball and baseball players (n = 247) from 11 high schools. Injury rates, locations, types; initial or subsequent injury; practice or game setting; positions played; seasonal trends. The overall incidence injury rate was 4.5/1000 athlete-exposures (AEs), with more injuries overall in softball players (5.6/1000 AEs) than in baseball players (4.0/1000 AEs). Baseball players had a higher initial injury rate (75.9/1000 AEs) than softball players (66.4/1000 AEs): rate ratio (RR) = 0.88, 95% confidence interval (CI) = 0.4, 1.7. The initial injury rate was higher than the subsequent injury rate for the overall sample (P softball (P Softball players were more likely to be injured in a game than were baseball players (RR = 1.92, 95% CI = 0.8, 4.3). Most injuries (77%) were mild (3.5/1000 AEs). The upper extremity accounted for the highest proportion of injuries (63.3%). The incidence of injury for pitchers was 37.3% and for position players was 15.3%. The rate of injury was highest during the first month of the season (7.96/1000 AEs). The incidence of injury was low for both softball and baseball. Most injuries were minor and affected the upper extremity. The injury rates were highest in the first month of the season, so prevention strategies should be focused on minimizing injuries and monitoring players early in the season.

2012-01-01

This study was designed to examine the relationship between deficits in empathy, emotional responsivity, and social behavior in adults with severe traumatic brain injury (TBI). A total of 21 patients with severe TBI and 25 control participants viewed six film clips containing pleasant, unpleasant, and neutral content whilst facial muscle responses, skin conductance, and valence and arousal ratings were measured. Emotional empathy (the Balanced Emotional Empathy Scale, BEES: self-report) and changes in drive and control in social situations (The Current Behaviour Scale, CBS: relative report) were also assessed. In comparison to control participants, those in the TBI group reported less ability to empathize emotionally and had reduced facial responding to both pleasant and unpleasant films. They also exhibited lowered autonomic arousal, as well as abnormal ratings of valence and arousal, particularly to unpleasant films. Relative reported loss of emotional control was significantly associated with heightened empathy, while there was a trend to suggest that impaired drive (or motivation) may be related to lower levels of emotional empathy. The results represent the first to suggest that level of emotional empathy post traumatic brain injury may be associated with behavioral manifestations of disorders of drive and control.

Adverse childhood experiences are significant risk factors for physical and mental illnesses in adulthood. Traumatic brain injury/concussion is a challenging condition where pre-injury factors may affect recovery. The association between childhood adversity and traumatic brain injury/concussion has not been previously reviewed. The research question addressed is: What is known from the existing literature about the association between adverse childhood experiences and traumatic brain injury/concussion in adults? All original studies of any type published in English since 2007 on adverse childhood experiences and traumatic brain injury/concussion outcomes were included. The literature search was conducted in multiple electronic databases. Arksey and O'Malley and Levac et al.'s scoping review frameworks were used. Two reviewers independently completed screening and data abstraction. The review yielded six observational studies. Included studies were limited to incarcerated or homeless samples, and individuals at high-risk of or with mental illnesses. Across studies, methods for childhood adversity and traumatic brain injury/concussion assessment were heterogeneous. A positive association between adverse childhood experiences and traumatic brain injury occurrence was identified. The review highlights the importance of screening and treatment of adverse childhood experiences. Future research should extend to the general population and implications on injury recovery. Implications for rehabilitation Exposure to adverse childhood experiences is associated with increased risk of traumatic brain injury. Specific types of adverse childhood experiences associated with risk of traumatic brain injury include childhood physical abuse, psychological abuse, household member incarceration, and household member drug abuse. Clinicians and researchers should inquire about adverse childhood experiences in all people with traumatic brain injury as pre-injury health conditions can

Our aim is to report the findings of the initial three years of road traffic injuries (RTI) surveillance at Karachi and to compare it with previously published RTI-related data from Pakistan and other low-and middle-income countries. Data were collected through the RTI surveillance programme at Karachi (RTIRP) from the five biggest emergency departments of the city, which receive almost all the major emergencies of the city for the period September 2006 till September 2009. A total of 99,272 victims were enlisted by the RTIRP during the study period. Annual incidence of RTI is calculated to be 184.3 per 100,000 populations and mortality is 5.7 per 100,000 populations. Eighty nine per cent of victims are male and 73% are between 15 and 44 years of age. Commonest road user to be affected is riders of two wheelers (45%). Only 7% of affected motorcyclists were found to be wearing helmets at the time of the accident. Trends of injuries remained uniform over the years. Most frequent injuries were external wounds, followed by orthopaedic injuries. On the basis of our surveillance system, we have presented the largest RTI-related data from a metropolitan city of Pakistan to date.

The diagnosis of nerve injury using thermotropic liquid crystal temperature strips was compared blindly and prospectively against operative findings in 36 patients requiring surgical exploration for unilateral upper limb lacerations with suspected nerve injury. Thermotropic liquid crystal strips were applied to affected and non-affected segments in both hands in all subjects. A pilot study showed that a simple unilateral laceration without nerve injury results in a cutaneous temperature difference between limbs, but not within each limb. Thus, for detection of a nerve injury, comparison was made against the unaffected nerve distribution in the same hand. Receiver operating characteristic curve analysis showed that an absolute temperature difference > or = 1.0 degrees C was diagnostic of a nerve injury (area under the curve = 0.985, sensitivity = 100%, specificity = 93.8%). Thermotropic liquid crystal strip assessment is a new, reliable and objective method for the diagnosis of traumatic peripheral nerve injuries. If implemented in the acute setting, it could improve the reliability of clinical assessment and reduce the number of negative surgical explorations.

The purpose is to create more awareness as well as emphasize the risk of permanent nerve injury as a complication of elbow arthroscopy. Patients who underwent elbow arthroscopy complicated by permanent nerve injury were retrospectively collected. Patients were collected using two strategies: (1) by word-of-mouth throughout the Dutch Society of Shoulder and Elbow Surgery, and the Leiden University Nerve Centre, and (2) approaching two medical liability insurance companies. Medical records were reviewed to determine patient characteristics, disease history and postoperative course. Surgical records were reviewed to determine surgical details. A total of eight patients were collected, four men and four women, ageing 21-54 years. In five out of eight patients (62.5%), the ulnar nerve was affected; in the remaining three patients (37.5%), the radial nerve was involved. Possible causes for nerve injury varied among patients, such as portal placement and the use of motorized instruments. A case series on permanent nerve injury as a complication of elbow arthroscopy is presented. Reporting on this sequel in the literature is little, however, its risk is not to be underestimated. This study emphasizes that permanent nerve injury is a complication of elbow arthroscopy, concurrently increasing awareness and thereby possibly aiding to prevention. IV, case series.

Use of infrared thermography for the diagnosis and grading of sprained ankle injuries

Oliveira, João; Vardasca, Ricardo; Pimenta, Madalena; Gabriel, Joaquim; Torres, João

2016-05-01

Ankle joint sprains are a common medical condition estimated to be responsible for 15-25% of all musculoskeletal injuries worldwide. The pathophysiology of the lesion can represent considerable time lost to injury, as well as long-term disability in up to 60% of patients. A percentage between 10% and 20% may complicate with chronic instability of the ankle joint and disability in walking, contributing to morbidity and poor life quality. Ankle sprains can be classified as grade I, II, or III, based on the extent of damage and number of ligaments affected. The diagnostic grading is important for setting further treatment and rehabilitation, since more severe injuries carries risk of recurrence, added morbidity and decrease in life quality. The aim of this work was to evaluate the adequacy of infrared thermography as a potential complimentary diagnostic tool of the distinct lesions grades. Evaluation of different thermographic values of the ankle region (in both affected and non-affected foot) was conducted for this purpose. The principal results to be highlighted are that some of the regions, namely anterior view for non defined time after injury analysis, and anterior, frontal, posterior and anterior talofibular ligament regions and proximal calcaneofibular ligament regions in acute lesions (herein defined as less than 6 h post-traumatic event) presented consistent profiles of variation. The analyses were performed considering affected and non-affected ankles results on plotted graphics representing termographic evaluation and grading of these lesions performed using ultrasound by experimented medical radiologists. An increase in temperature values was observed when progressing from mild to severe ankle sprain injuries, with these regions presenting lower values for the affected ankle when compared to the non-affected ankle in all the analysis performed. The remaining analysed regions did not present the same variations. Statistical analysis using Kruskal

Unlike with anterior cruciate ligament injury, little is known about the prevalence of intra-articular pathology associated with isolated posterior cruciate ligament (PCL) injury in the knee. The objectives of this study were to characterize and identify the frequency of meniscal tears and osteochondral injuries in these patients, and to see if management might be affected. Altogether, 48 knee MRI exams with isolated PCL tears were evaluated for the presence of: grade and location of PCL tear, meniscal tear, articular chondral lesion, bone bruise, and fracture. Comparisons between PCL tear grade and location, as well as mechanism of injury when known, with the presence of various intra-articular pathologies, were made using the chi-square or Fisher's exact test as appropriate. In all, 69 % of isolated PCL tears occur in the midsubstance, 27 % proximally. Meniscal tears were seen in 25 % of knees, involving all segments of both menisci, except for the anterior horn medial meniscus. Altogether, 23 % had focal cartilage lesions, usually affecting the central third medial femoral condyle and medial trochlea, while 12.5 % of knees had fractures, and 48 % demonstrated bone bruises, usually involving the central to anterior tibiofemoral joint. The presence of a fracture (p = 0.0123) and proximal location of PCL tear (p = 0.0016) were both associated with the hyperextension mechanism of injury. There were no statistically significant associations between PCL tear grade and presence of intra-articular abnormality. Potentially treatable meniscal tears and osteochondral injuries are relatively prevalent, and demonstrable on MRI in patients with isolated acute PCL injury of the knee. (orig.)

Occupational injuries in the Finnish furniture industry.

Aaltonen, M V

1996-06-01

The purpose of the study was to determine the types of occupational injuries that occur in the Finnish furniture industry and to see whether they differ as regards production type and company size. During a one-year registration period accident events, the actual and potential severity of the injuries, the causes of the accidents, and the measures needed to prevent such accidents were examined in 18 Finnish furniture factories of different types. An analysis of covariance determined the variables affecting the actual and potential severity of the injuries. The 214 accidents registered were lost-time injuries; two of them resulted in slight partial loss of fingertips. The disabling injury rate was 14.4 per 100 workers per year. Wooden furniture production and kitchen cupboard production in large companies had the highest rate. Accidents involving machines comprised half of the material. Saws were the most common machine type. Forty-two percent of the injuries could have been more severe; one injury could have been fatal. The injured persons and their foremen identified the causal factors of the accidents and the needed safety countermeasures well. Sixty-six percent of the causes and 65% of the safety countermeasures were associated with the actions of the workers and the workplace procedures. Nevertheless, only 6% of the identified safety countermeasures were put into force. It was estimated that, in 1987, 2000 on-site accidents leading to at least first-aid at some health care center occurred in the Finnish furniture industry. Special efforts should be taken to improve safety in furniture production in Finland.

Several authors have analyzed the incidence of injuries in a given sport, but only a few have examined the exposure-related incidence of injuries in different types of sports using the same methodology. Analysis of the incidence, circumstances, and characteristics of injuries in different team sports during the 2004 Olympic Games. Cohort study; Level of evidence, 2. During the 2004 Olympic Games, injuries in 14 team sport tournaments (men's and women's soccer, men's and women's handball, men's and women's basketball, men's and women's field hockey, baseball, softball, men's and women's water polo, and men's and women's volleyball) were analyzed. After each match, the physician of the participating teams or the official medical representative of the sport completed a standardized injury report form. The mean response rate was 93%. A total of 377 injuries were reported from 456 matches, an incidence of 0.8 injuries per match (95% confidence interval, 0.75-0.91) or 54 injuries per 1000 player matches (95% confidence interval, 49-60). Half of all injuries affected the lower extremity; 24% involved the head or neck. The most prevalent diagnoses were head contusion and ankle sprain. On average, 78% of injuries were caused by contact with another player. However, a significantly higher percentage of noncontact (57%) versus contact injuries (37%) was expected to prevent the player from participating in his or her sport. Significantly more injuries in male players (46%) versus female players (35%) were expected to result in absence from match or training. The incidence, diagnosis, and causes of injuries differed substantially between the team sports. The risk of injury in different team sports can be compared using standardized methodology. Even if the incidence and characteristics of injuries are not identical in all sports, prevention of injury and promotion of fair play are relevant topics for almost all team sports.

Isolated injuries to the posterolateral corner of the knee are a rare and commonly missed injury associated with athletic trauma, motor vehicle accidents, and falls. Delayed or missed diagnoses can negatively impact patient prognosis, contributing to residual instability, chronic pain, and failure of surgical repair to other ligaments. A 44-year-old male CrossFit athlete presented with a history of two non-contact hyperextension injuries to his left knee while walking on ice. The only positive finding was the Dial Test at 30 degrees of knee flexion, indicative of an isolated posterolateral corner injury. After a delay in diagnosis, the patient underwent a reconstruction of the posterolateral corner and subsequent rehabilitation. Early recognition of this injury is important as this can affect the prognosis and activities of daily living of the patient. This case will discuss the clinical presentation, diagnostic procedures, and management of an isolated posterolateral corner injury and highlight the importance of early recognition and referrals from primary contact healthcare practitioners.

CrossFit is a strength and conditioning program that has gained widespread recognition, with 11,000 affiliated gyms worldwide. The incidence of injuries during CrossFit training is poorly analyzed. To investigate the incidence of injuries for persons participating in CrossFit. Risk factors for injury and injury mechanisms were also explored through athlete demographics and characteristics. Descriptive epidemiology study. A questionnaire that focused on injury incidence in CrossFit in the past year and included data on athlete demographics and characteristics was distributed to all 130 CrossFit gyms in the Netherlands and was also available online in active Facebook groups. Data were collected from July 2015 to January 2016. Inclusion criteria consisted of age ≥18 years and training at a registered CrossFit gym in the Netherlands. A total of 553 participants completed the survey. Univariable and multivariable generalized linear mixed models were used to identify potential risk factors for injury. A total of 449 participants met the inclusion criteria. Of all respondents, 252 athletes (56.1%) sustained an injury in the preceding 12 months. The most injured body parts were the shoulder (n = 87, 28.7%), lower back (n = 48, 15.8%), and knee (n = 25, 8.3%). The duration of participation in CrossFit significantly affected the injury incidence rates (CrossFit was 56.1%. The most frequent injury locations were the shoulder, lower back, and knee. A short duration of participation (<6 months) was significantly associated with an increased risk for injury.

Identifying vulnerable populations to death and injuries from residential fires.

Gilbert, Stanley W; Butry, David T

2017-08-03

This study proposes and evaluates the theory that people who are susceptible to injury in residential fires are not susceptible to death in residential fires and vice versa. It is proposed that the population vulnerable to death in residential fires can be proxied by 'frailty', which is measured as age-gender adjusted fatality rates due to natural causes. This study uses an ecological approach and controls for exposure to estimate the vulnerability of different population groups to death and injury in residential fires. It allows fatalities and injuries to be estimated by different models. Frailty explains fire-related death in adults while not explaining injuries, which is consistent with the idea that deaths and injuries affect disjoint populations. Deaths and injuries in fire are drawn from different populations. People who are susceptible to dying in fires are unlikely to be injured in fires, and the people who are susceptible to injury are unlikely to die in fires. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Anterior cruciate ligament (ACL) injuries can have negative consequences on the careers of National Football League (NFL) players, however no study has ever analyzed the financial impact of these injuries in this population. To quantify the impact of ACL injuries on salary and career length in NFL athletes. Cohort study; Level of evidence, 3. Any player in the NFL suffering an ACL injury from 2010 to 2013 was identified using a comprehensive online search. A database of NFL player salaries was used to conduct a matched cohort analysis comparing ACL-injured players with the rest of the NFL. The main outcomes were the percentage of players remaining in the NFL and mean salary at 1, 2, 3, and 4 years after injury. Cohorts were subdivided based on initial salary: group A, $2,000,000. Mean cumulative earnings were calculated by multiplying the percentage of players remaining in the league by their mean salaries and compounding this each season. NFL athletes suffered 219 ACL injuries from 2010 to 2013. The 7504 other player seasons in the NFL during this time were used as controls. Significantly fewer ACL-injured players than controls remained in the NFL at each time point (P negatively affected. This demonstrates the degree of negative impact these injuries have on the careers of NFL players. It also indicates that a player's standing within the league before injury strongly influences how much an ACL injury will affect his career.

The current study explored the association between the business cycle and the incidence of workplace injuries to identify cyclically sensitive industries and the relative contribution of physical capital and labor utilization within industries. Bureau of Labor Statistics nonfatal injury rates from 1976 through 2007 were examined across five industry sectors with respect to several macroeconomic indicators. Within industries, injury associations with utilization of labor and physical capital over time were tested using time series regression methods. Pro-cyclical associations between business cycle indicators and injury incidence were observed in mining, construction, and manufacturing but not in agriculture or trade. Physical capital utilization was the highest potential contributor to injuries in mining while labor utilization was the highest potential contributor in construction. In manufacturing each effect had a similar association with injuries. The incidence of workplace injury is associated with the business cycle. However, the degree of association and the mechanisms through with the business cycle affects the incidence of workplace injuries was not the same across industries. The results suggest that firms in the construction, manufacturing, and mining industries should take additional precautionary safety measures during cyclical upturns. Potential differences among industries in the mechanisms through which the business cycle affects injury incidence suggest different protective strategies for those industries. For example, in construction, additional efforts might be undertaken to ensure workers are adequately trained and not excessively fatigued, while safety procedures continue to be followed even during boom times.

Etherton, J R; Trump, T R; Jensen, R C

1981-01-01

Operators of metal-working lathes are one of the largest manufacturing machine worker populations in the United States. Machines (other than vehicular) account for over 10% of occupational injuries each year. An estimated 3,400 operators of metal-working lathes suffer lost-time injuries annually in the United States. Some of these are fatal. Therefore an investigation was undertaken to determine methods for reducing injuries to lathe operators. Three methods were used: (i) review of injury reports, (ii) human factors analysis, and (iii) fault-tree procedures. The investigation followed the man-machine systems approach of looking for injury-producing dysfunctions between the lathe and the lathe operator. The major sources of injury were found to be chips and workholding devices. Secondary tasks were found to be more hazardous than is generally recognized. The use of three methods for approaching the problem was found to be useful in that injury controls were identified which are likely to be adopted because of their potential for improving safety without adversely affecting productivity.

Full Text Available Findings about the relation between musculoskeletal injuries and training patterns in orienteering athletes are sparse. Therefore, the musculoskeletal injuries and training patterns of 31 Swiss elite orienteering athletes aged 18-19 years were analyzed in a retrospective study. Individual training diaries and medical records were used to assess training data and injury history, respectively. Group comparisons and a multiple linear regression (MLR were performed for statistical analysis. The junior elite orienteering athletes performed 7.38 ± 2.00 training sessions weekly, with a total duration of 455.75 ± 98.22 minutes. An injury incidence rate (IIR of 2.18 ± 2.13 injuries per 1000 hours of training was observed. The lower extremity was affected in 93% of all injuries, and the knee (33% was the most commonly injured location. The MLR revealed that gender and six training variables explained 60% of the variance in the injury severity index in this study. Supported by the low IIR in the observed age group, the training protocol of the junior elite orienteering athletes was generally adequate. In comparison to elite track, marathon, and orienteering athletes, the junior elite athletes performed less high-intensity interval training (HIIT. However, more frequent HIIT seems to be a protective factor against injuries.

Injuries of the hand can cause significant functional impairment, diminished quality of life and delayed return to work. However, the incidence and functional outcome of hand injuries in polytrauma patients is currently unknown. The aim of this study was to determine the incidence, distribution and functional outcome of fractures and dislocation of the hand in polytrauma patients. A single centre retrospective cohort study was performed at a level 1 trauma centre. Polytrauma was defined as patients with an Injury Severity Score of 16 or higher. Fractures and dislocations to the hand were determined. All eligible polytrauma patients with hand injuries were included and a Quick Disability of Arm, Shoulder and Hand questionnaire (QDASH) and Patient-Rated Wrist/Hand Evaluation (PRWHE) were administered. Patients were contacted 1-6 years after trauma. In a cohort of 2046 polytrauma patients 72 patients (3.5%) suffered a hand injury. The functional outcome scores of 52 patients (72%) were obtained. The Metacarpal (48%) and carpal (33%) bones were the most frequently affected. The median QDASH score for all patients with hand injury was 17 (IQR 0-31) and the PRWHE 14 (IQR 0-41). Patients with a concomitant upper extremity injury (p=0.002 for PRWHE, p0.006 for QDASH) and those with higher ISS scores (p=0.034 for PRWHE, QDASH not significant) had worse functional outcome scores. As an example, of the 5 patients with the worst outcome scores 3 suffered an isolated phalangeal injury, all had concomitant upper extremity injury or neurological injuries (3 plexus injuries, 1 severe brain injury). The incidence of hand injuries in polytrauma patients is 3.5%, which is relatively low compared to a general trauma population. Metacarpal and carpal bones were most frequently affected. The functional extremity specific outcome scores are highly influenced by concomitant injuries (upper extremity injuries, neurological injuries and higher ISS). Copyright © 2017 Elsevier Ltd. All

Many countries have hypergravity training centers using centrifuges for pilots to cope with a high gravity (G) environment. The high G training carries potential risk for the development of spinal injury. However, no studies evaluated the influence of centrifuge training on the spines of asymptomatic fighter pilots on a large scale. Study subjects were 991 male fighter pilots with high G training at one institution. Subject variables included information about physical characteristics, flight hours of pilots prior to the training, and G force exposure related factors during training. The two dependent variables were whether the pilots developed acute spinal injury after training and the severity of the injury (major/minor). The incidence of acute spinal injury after high G training was 2.3% (23 of 991 subjects). There were 19 subjects who developed minor injury and 4 subjects who developed a herniated intervertebral disc, which is considered a major injury. In multivariate analysis, only the magnitude of G force during training was significantly related to the development of acute spinal injury. However, there was no significant factor related to the severity of the injury. These results suggest that high G training could cause negative effects on fighter pilots' spines. The magnitude of G force during training seemed to be the most significant factor affecting the occurrence of acute spinal injury.

Bomb blast mass casualty incidents: initial triage and management of injuries.

Science.gov (United States)

Goh, S H

2009-01-01

Bomb blast injuries are no longer confined to battlefields. With the ever present threat of terrorism, we should always be prepared for bomb blasts. Bomb blast injuries tend to affect air-containing organs more, as the blast wave tends to exert a shearing force on air-tissue interfaces. Commonly-injured organs include the tympanic membranes, the sinuses, the lungs and the bowel. Of these, blast lung injury is the most challenging to treat. The clinical picture is a mix of acute respiratory distress syndrome and air embolism, and the institution of positive pressure ventilation in the presence of low venous pressures could cause systemic arterial air embolism. The presence of a tympanic membrane perforation is not a reliable indicator of the presence of a blast injury in the other air-containing organs elsewhere. Radiological imaging of the head, chest and abdomen help with the early identification of blast lung injury, head injury, abdominal injury, eye and sinus injuries, as well as any penetration by foreign bodies. In addition, it must be borne in mind that bomb blasts could also be used to disperse radiological and chemical agents.

2010-05-01

Combat injuries are more often associated with blast, penetrating, and high-energy mechanisms than civilian trauma, generating controversy about the management of combat colonic injury. Despite implementation of mandatory colostomy in World War II, recent civilian data suggest that primary repair without diversion is safe and feasible. This study describes the modern management of battle-related colonic injuries and seeks to determine whether management strategy affects early complications. Records from the combat theater (downrange) and tertiary referral center in Germany were retrospectively reviewed from 2005 to 2006. Patient characteristics, management strategy, treatment course, and early complications were recorded. Comparison groups by management strategy were as follows: primary repair, diversion, and damage control. A total of 133 (97% male) patients sustained colonic injuries from penetrating (71%), blunt (5%), and blast (23%) mechanisms. Average injury severity score was 21 and length of stay in the referral center was 7.1 days. Injury distribution was 21% ascending, 21% descending, 15% transverse, 27% sigmoid, and 25% rectum. Downrange complications for primary repair, initial ostomy, and damage control groups were 14%, 15%, and 30%, respectively. On discharge from the center, 62% of patients had undergone a diversion. The complication rate was 18% overall and was unrelated to management strategy (P = .16). Multivariate analysis did not identify independent predictors of complications. Early complications were similar by mechanism, anatomic location, severity of injury, and management strategy. More diversions were performed for rectosigmoid injury. Good surgical judgment allows for low morbidity and supports primary repair in selected cases. Damage control surgery is effective in a multinational theater of operations.

Full Text Available PURPOSE. The aim of our retrospective study was to analyze the patterns of associated thoracic injuries in patients underwent blunt chest trauma and rib fractures. METHODS. The study included 212 patients with rib fractures due to blunt thoracic trauma. The mechanism of trauma, the type of rib fracture and the type of associated injuries were analyzed. RESULTS. The patients were divided in two groups according to the number of fractured ribs-group I included the patients with up to two fractured ribs (72 patients-33,9%, and group II – with ≥3 fractured ribs (140 patients-66,1%. Associated chest injuries were present in 36 of the patients from group I (50%, and in 133 patients from group II (95%. Pulmonary contusion was the most common intrathoracicinjurie-65,6% of the cases. The mean hospital stay was 8, 7 days. The lethality rate was 16,9% -all of them due to the associated chest injuries. CONCLUSIONS. The mortality related to rib fractures is affected by the associated thoracic injuries, the advanced age, and the number of fractured ribs.

Face and Word Recognition Can Be Selectively Affected by Brain Injury or Developmental Disorders.

Science.gov (United States)

Robotham, Ro J; Starrfelt, Randi

2017-01-01

Face and word recognition have traditionally been thought to rely on highly specialised and relatively independent cognitive processes. Some of the strongest evidence for this has come from patients with seemingly category-specific visual perceptual deficits such as pure prosopagnosia, a selective face recognition deficit, and pure alexia, a selective word recognition deficit. Together, the patterns of impaired reading with preserved face recognition and impaired face recognition with preserved reading constitute a double dissociation. The existence of these selective deficits has been questioned over the past decade. It has been suggested that studies describing patients with these pure deficits have failed to measure the supposedly preserved functions using sensitive enough measures, and that if tested using sensitive measurements, all patients with deficits in one visual category would also have deficits in the other. The implications of this would be immense, with most textbooks in cognitive neuropsychology requiring drastic revisions. In order to evaluate the evidence for dissociations, we review studies that specifically investigate whether face or word recognition can be selectively affected by acquired brain injury or developmental disorders. We only include studies published since 2004, as comprehensive reviews of earlier studies are available. Most of the studies assess the supposedly preserved functions using sensitive measurements. We found convincing evidence that reading can be preserved in acquired and developmental prosopagnosia and also evidence (though weaker) that face recognition can be preserved in acquired or developmental dyslexia, suggesting that face and word recognition are at least in part supported by independent processes.

We previously reported that functional recovery of rats with spinal cord contusions can occur after acute transplantation of neural stem cells distal to the site of injury. To investigate the effects of timing of administration of human neural stem cell (hNSC) distal to the site of spinal cord injury on functional outcomes in an animal model. Thirty-six adult female Long-Evans hooded rats were randomized into three experimental and three control groups with six animals in each group. The T10 level was exposed via posterior laminectomy, and a moderate spinal cord contusion was induced by the Multicenter Animal Spinal Cord Injury Study Impactor (MASCIS, W.M. Keck Center for Collaborative Neuroscience, Piscataway, NJ, USA). The animals received either an intrathecal injection of hNSCs or control media through a separate distal laminotomy immediately, one week or four weeks after the induced spinal cord injury. Observers were blinded to the interventions. Functional assessment was measured immediately after injury and weekly using the Basso, Beattie, Bresnahan (BBB) locomotor rating score. A statistically significant functional improvement was seen in all three time groups when compared to their controls (acute, mean 9.2 vs. 4.5, P=0.016; subacute, mean 11.1 vs. 6.8, P=0.042; chronic, mean 11.3 vs. 5.8, P=0.035). Although there was no significant difference in the final BBB scores comparing the groups that received hNSCs, the group which achieved the greatest improvement from the time of cell injection was the subacute group (+10.3) and was significantly greater than the chronic group (+5.1, P=0.02). The distal intrathecal transplantation of hNSCs into the contused spinal cord of a rat led to significant functional recovery of the spinal cord when injected in the acute, subacute and chronic phases of spinal cord injury (SCI), although the greatest gains appeared to be in the subacute timing group.

Full Text Available The growth of participation of youth in sports is accompanied by an increase in the number of musculoskeletal injuries, especially in contact sports. Basketball gained prominence among contact sports not only for its plastic and beauty of their games, but because it is a sport that demands much of its practitioners, and in the case of young athletes, this requirement can endanger children and adolescents are not properly monitored for health professionals sports. In this study we can see that the ankle is the most affected, followed by knee and fingers and wrists. The mechanisms of injury most frequently reported were sprains, after the bruises and fractures. Highlight for disturbances dorsolumbar, pointed out by many authors.

The consequence of a pancreas injury during the procurement for islet isolation purpose is unknown. The goal of this work was to assess the injuries of the pancreata procured for islet isolation, and to determine their effect on the islet yield. Between January 2007 and October 2013, we prospectively documented every injury of the pancreata processed in our centre for islet isolation. Injuries involving the main duct were classified as major, the others as minor. Donors' characteristics and islet yields were compared between the groups of injuries. A pancreas injury was identified in 42 of 452 pancreata received for islet isolation (9.3%). In 15 cases, the injury was major (3.3% of all pancreata). Although a minor injury did not affect the islet yield, a major injury was significantly associated with unfavourable outcomes (postpurification mean islet equivalent of 364 ± 181, 405 ± 190 and 230 ± 115 × 10(3) for absence of injury, minor injury and major injury, respectively). A major injury was significantly more prevalent in lean and short donors. We recommend assessing the quality of the pancreas in the islet isolation centre before starting the isolation procedure. Each centre should determine its own policy based on its financial resources and on the wait list. © 2014 Steunstichting ESOT.

As a collision sport, football carries a significant risk of injury, as indicated by the large number of pediatric football-related injuries seen in emergency departments. There is little information in the medical literature focusing on the age-related injury patterns of this sport. Our purpose was to evaluate the types of football-related injuries that occur in children and adolescents and assess which patient characteristics, if any, affect injury pattern. Retrospective chart review was performed of football-related injuries treated at a level 1 pediatric referral hospital emergency department and surrounding urgent care clinics between January 2010 and January 2014. Patients with e-codes for tackle football selected from the electronic medical record were divided into 4 age groups: younger than 8 years old, 8 to 11, 12 to 14, and 15 to 18 years. Data collected included diagnosis codes, procedure codes, and hospital admission status. Review identified 1494 patients with 1664 football-related injuries, including 596 appendicular skeleton fractures, 310 sprains, 335 contusions, 170 closed head injuries, 62 dislocations, 9 spinal cord injuries, and 14 solid organ injuries. There were 646 (43.2%) athletes with upper extremity injuries and 487 (32.6%) with injuries to the lower extremity. Hospital admissions were required in 109 (7.3%) patients. Fracture was the most common injury in all four patient age groups, but occurred at a lower rate in the 15 to 18 years old age group. The rate of soft tissue injury was higher in the 15 to 18 years old age group. The rate of closed head injury, which included concussions, was highest in the younger than 8 years old age group. Age does influence the rates of certain football-related injuries in children and adolescents. Fractures decrease with increasing age, while the rate of soft tissue trauma increases with increasing age. Younger patients (younger than 8 y old) trended toward higher rates of closed head injury compared

War injury is a public health problem that warrants global attention. This study aims to determine the burden of injury during a complex emergency in sub-Saharan Africa. To determine the magnitude, causes, distribution, risk factors and cumulative burden of injury in a population experiencing armed conflict in northern Uganda since 1986 and to evaluate the living conditions and access to care for injury victims, we took a multistage, stratified, random sampling from the Gulu district to determine the rates of injury from 1994 to 1999. The Gulu district is endemic for malaria, tuberculosis, HIV and malnutrition and has a high maternal death rate. It is 1 of 3 districts in northern Uganda affected by war since 1986. The study participants included 8595 people from 1475 households. Of these, 73.0% lived in temporary housing, 46.0% were internally displaced and 81.0% were under 35 years of age. Trained interviewers administered a 3-part household survey in the local language. Quantitative data on injury, household environment, health care and demography were analyzed. Qualitative data from part 3 of the survey will be reported elsewhere. A similar rural district (Mukono) not affected by war was used for comparison. We studied injury risk factors, mortality and disability rates, accumulated deaths, access to care and living conditions. Of the study population, 14% were injured annually: gunshot injuries were the leading cause of death. The annual death rate from war injury was 7.8/1000 (95% confidence interval [CI] 7.0-8.5) and the disability rate was 11.3/1000 (95% CI 10.4-12.2). The annual excess injury mortality was 6.85/1000. Only 4.5% of the injured were combatants. Fifty percent of the injured received first aid, but only 13.0% of those who died reached hospital. The injury mortality in Gulu was 8.35-fold greater than that for Mukono. The crisis in Gulu can be considered a complex political emergency. Protracted conflicts should not be ignored because of a low

Childhood injuries, an important public health issue, globally affects more than 95% of children living in low-and middle-income countries. The objective of this study is to describe the epidemiology of childhood unintentional injuries in Karachi, Pakistan with a specific focus on those occurring within the home environment. This was a secondary analysis of a childhood unintentional injury surveillance database setup in the emergency department of the Aga Khan Hospital, Karachi, Pakistan for 3 months. The data was collected by interviewing caretakers of children under 12 years of age presenting with an unintentional injury to the emergency departments of the four major tertiary care hospitals of Karachi, Pakistan. The surveillance included 566 injured children of which 409 (72%) injuries had taken place at/around home. Of 409 children, 66% were males and mostly between 5 and 11 years of age. Injuries commonly occurred during play time (51%). Fall (59%), dog bites (11%) and burns (9%) were the commonest mechanisms of injury. The majority of the children (78%) were directly discharged from the emergency room with predicted short term disability (42%). There were 2 deaths in the emergency department both due to falls. Childhood injury surveillance system provides valuable in-depth information on child injuries. The majority of these unintentional childhood injuries occur at home; with falls, dog bites and burns being the most common types of unintentional childhood home injuries. Specific surveillance systems for child injuries can provide new and valuable information for countries like Pakistan.

Up to 32.2% of patients in a burn center suffer from electrical injuries. Of these patients, 2-4% present with lightning injuries. In Germany, approximately 50 people per year are injured by a lightning strike and 3-7 fatally. Typically, people involved in outdoor activities are endangered and affected. A lightning strike usually produces significantly higher energy doses as compared to those in common electrical injuries. Therefore, injury patterns vary significantly. Especially in high voltage injuries and lightning injuries, internal injuries are of special importance. Mortality ranges between 10 and 30% after a lightning strike. Emergency medical treatment is similar to common electrical injuries. Patients with lightning injuries should be transported to a regional or supraregional trauma center. In 15% of all cases multiple people may be injured. Therefore, it is of outstanding importance to create emergency plans and evacuation plans in good time for mass gatherings endangered by possible lightning.

Hand injuries can result in significant time away from competition for professional basketball players. Time to return to play after hand injuries in elite athletes has not been well described. To report the return to play from metacarpal fractures, phalangeal fractures, and thumb ligament tears in National Basketball Association (NBA) players over a 5-year period. Descriptive epidemiology study. The NBA transaction report was analyzed from January 2009 to May 2014. Players were identified if they were added to the inactive list (IL), missed games due to their injury, or underwent surgery as a result of hand injury. Number of games missed due to injury, days spent on the IL, and age at injury were calculated by injury type and location. One hundred thirty-seven injuries were identified: 39 injuries to the hand and 98 injuries to the finger. Three major injury patterns were identified and analyzed: metacarpal fractures (n = 26), phalangeal fractures (n = 33), and thumb ligament tears (n = 9). The type of injury sustained affected return to play ( P basketball players can lead to prolonged periods of time away from competition, especially after surgery. This study provides guidelines on expected return to play in the NBA after these common hand injuries.

Accurate workplace injury data are useful in the prioritization of prevention strategies. In the UK, physicians report workplace ill-health data within The Health and Occupation Research (THOR) network, including injury case reports. To compare workplace injury data reported by occupational physicians (OPs) and general practitioners (GPs) to THOR. Injury cases reported by OPs and GPs, reported to THOR between 2006 and 2012 were analysed. Demographics, industrial groups, nature of injury, kind of accident and site of injury were compared. Data on sickness absence for workplace injuries reported by GPs were investigated. In total, 2017 workplace injury cases were reported by OPs and GPs. Males were more likely to sustain a workplace accident than females. Sprains and strains were reported most often, with the upper limbs being affected most frequently. Slips, trips and falls were identified as important causal factors by both OPs and GPs. Psychological injuries also featured in THOR reporting, with a higher proportion reported by OPs (21%) than by GPs (3%). The proportion of people classified as 'unfit' by GPs reduced following the introduction of the 'fit' note. THOR reports returned by OPs and GPs provide a valuable source of information of workplace injury data, and complement other sources of information, such as the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations and the Labour Force Survey. © The Author 2015.

Prevention of sport injuries and illnesses is a focus for epidemiological surveillance. To record and analyse all sports injuries and illnesses registered during the second Asian Beach Games. A descriptive epidemiological study using the International Olympic Committee Surveillance system to register injuries and illnesses during the second Asian Beach Games. The second Asian Beach Games hosted 1132 athletes from 43 countries competing in 14 beach sports. All National Olympic Committees' physicians of the participating teams were invited to report all injuries and illnesses. In addition, medical officers at the different Olympic venues and the main Olympic village reported injuries and illnesses treated at the clinics on a daily basis. A total of 177 injuries were reported equating to an incidence rate of 156.4 per 1000 registered athletes. Tent pegging recorded the highest incidence of injuries with 357 per 1000 registered athletes. The most prevalent injuries were in the foot/toe with 14.1% of all reported injuries. The majority of injuries were incurred during competition (75.4%). In addition, the most common mechanism of injury was contact with another athlete (n=42, 23.7%) and combined sudden and gradual overuse contributed to 30% of the total injury burden. Furthermore, 118 illnesses were reported resulting in an incidence rate of 104.2 illnesses per 1000 registered athletes. The most affected system was the respiratory tract (39.1%) with infection being the most common cause (n=33, 38.0%). The incidence of injury and illness differed significantly among the 14 sports. The data indicate that the risk of injury from beach games is sport dependant. This means that any preventive measures have to be tailored for each discipline. Furthermore, the study showed that respiratory infections are the commonest illness in beach sports and therefore, event organisers should focus improving public health measures and hygiene awareness.

Full Text Available Neuropsychiatric or cognitive disturbances are common complications after traumatic brain injury. They are commonly regarded as irreversible sequelae of organic brain injuries. We report a case of hypopituitarism in a 77-year-old man who presented with long-term neuropsychiatric disturbances, including cognitive impairment, disturbed sleep patterns, personality change, loss of affect, and visual and auditory hallucinations after a traumatic subdural hemorrhage. The treatment response to hormone replacement therapy was nearly complete. Hypopituitarism is rarely considered in patients who sustain traumatic brain injury and the neuropsychiatric manifestations of posttraumatic hypopituitarism have rarely been reported. This case highlights the importance of hypopituitarism as a potential reversible cause of neuropsychiatric disturbances after traumatic brain injury.

Athletes typically maintain rigorous training and work programs to be able to participate in competitions. An injury that occurs during the competition that causes withdrawal from the competition and a possible departure from sports, can render results athletes' and their support staff's efforts as meaningless. The early detection of injuries in the competition and developing preventive training programs can help ensure that participating in competitions and the associated preparatory efforts are not wasted. In this study, the sports injuries discussed occurred during training and competition events of the Turkish Shooting Sportive group. Body parts of injuries are determined and exercise programs focused on the affected body parts are developed. A total of 729 athletes (285 female, 444 male) who participated in Turkish Shooting Sports Championship during the 2010-2011 competition period participated in the study. Athletes were given a questionnaire that was developed prior to the event, and the questionnaire was filled in during interviews conducted one-on-one. Data was collected from the questionnaire and SPSS v.16.0 was used to analyze the results. The study was completed in six months. The results showed that the most of the injuries that occurred during training were strain and muscle tears whereas most of the injuries occurred during the actual competition were strain, muscle tears, tendinitis, and sprain. The results also indicated that during training, the most frequently-occurring injuries were in shoulder, calf-thigh, hand and wrist; whereas during the competition, it was manifested in the shoulder, foot and ankle. Muscle strengthening, stretching and proprioception exercises for these body parts should be included as part of the athletic training program.

Full Text Available BACKGROUND: Urinary Kidney Injury Molecule 1 (KIM-1 is a proximal tubular injury biomarker for early detection of acute kidney injury (AKI, with variable performance characteristics depending on clinical and population settings. METHODS: Meta-analysis was performed to assess the diagnostic value of urinary KIM-1 in AKI. Relevant studies were searched from MEDLINE, EMBASE, Pubmed, Elsevier Science Direct, Scopus, Web of Science, Google Scholar and Cochrane Library. Meta-analysis methods were used to pool sensitivity and specificity and to construct summary receiver operating characteristic (SROC curves. RESULTS: A total of 2979 patients from 11 eligible studies were enrolled in the analysis. Five prospective cohorts, two cross-sectional and four case-control studies were identified for meta-analysis. The estimated sensitivity of urinary KIM-1 for the diagnosis of AKI was 74.0% (95% CI, 61.0%-84.0%, and specificity was 86.0% (95% CI, 74.0%-93.0%. The SROC analysis showed an area under the curve of 0.86(0.83-0.89. Subgroup analysis suggested that population settings and detection time were the key factors affecting the efficiency of KIM-1 for AKI diagnosis. LIMITATION: Various population settings, different definition of AKI and Serum creatinine level used as the standard might have influence on AKI diagnosis. The relatively small number of studies and heterogeneity between them also affected the evaluation. CONCLUSION: Urinary KIM-1 may be a promising biomarker for early detection of AKI with considerable predictive value, especially for cardiac surgery patients, and its potential value needs to be validated in large studies and across a broader scope of clinical settings.

Karate enjoys great popularity both in professional and recreational sports and can be classified into full, half and low contact styles. The aim of this study was the analysis of sports injuries in Kyokushinkai (full contact) and traditional Karate (semi-contact). In a retrospective study design, 215 active amateur karateka (114 full contact, 101 semi-contact) were interviewed by means of a standardised questionnaire regarding typical sport injuries during the last 36 months. Injuries were categorised into severity grade I (not requiring medical treatment), grade II (single medical treatment), grade III (several outpatient medical treatments) and grade IV (requiring hospitalisation). In total, 217 injuries were reported in detail. 125 injuries (58%) occurred in full contact and 92 (42%) in semi-contact karate. The time related injury rate of full contact karateka was 1.9/1000 h compared to 1.3/1000 h of semi-contact karateka (p injuries were musculoskeletal contusions (33% full contact, 20% semi-contact), followed by articular sprains with 19% and 16%. The lower extremity was affected twice as often in full contact (40%) as in semi-contact (20%) karate. Training injuries were reported by 80% of the full contact and 77% of the semi-contact karateka. Most injuries, both in training and competition, occurred in kumite. 75% of the reported injuries of full contact and 70% of semi-contact karateka were classified as low grade (I or II). The high rate of injuries during training and kumite (sparring) points to specific prevention goals. The emphasis should be put on proprioceptive training and consistent warm-up. In the actual competition the referees play a vital role regarding prevention. © Georg Thieme Verlag KG Stuttgart · New York.

The aim of this study was to evaluate the effect and related mechanisms of Mesenchymal stem cells (MSCs) and Angiotensin converting enzyme II (ACE II) on acute lung injury (ALI). MSCs were separated from umbilical cord cells, and the changes of phenotype before and after ACE II silence were observed using Flow Cytometer. ALI model was induced by 10 mg/mL bleomycin in 60 Balb/c mice, and the rest 8 mice were regarded as the baseline group. The mice were randomly divided into four groups (n = 15): control, ACE II, stem, and stem + ACE II. The apoptotic index (AI) was calculated using TUNEL, and the detection of protein and mRNA of Bax, Bak and p53, Bcl-2, Grp78, CHOP and Caspase 12 were used by western-blot and RT-PCR, respectively. The umbilical cord cells differentiated into stable MSCs about 14 days, and ACE II transfection reached a peak at the 5th day after transfection. ACE II silence did not affect the phenotype of MSCs. All the proteins and mRNAs expression except Bcl-2 in the stem and stem + ACE II were significantly lower than those in control from 8 h (p ACE II performed a better effect than single stem in most indexes, including AI (p ACE II can significantly suppress apoptosis in ALI mice, and may be an effective clinical treatment for ALI.

Regulations controlling the sport of paragliding were issued in April 1987 by the German Department of Transportation. The growing popularity of this sport has led to a steady increase in the number of associated injuries. This study presents the incidence, localization and degree of injuries associated with paragliding documented in Germany, Austria and Switzerland. The 283 injuries suffered by 218 paragliders were documented in the period 1987-1989: 181 occurred during landing, 28 during starting procedures and nine during flight. The mean patient age was 29.6 years. There were 34.9% spinal injuries, 13.4% upper extremity injuries and 41.3% lower limb injuries. Over half of these injuries were treated surgically and in 54 instances permanent disability remained. In paragliding the lower extremities are at greatest risk of injury during landing. Proper equipment, especially sturdy footwear, exact training in landing techniques as well as improved instruction in procedures during aborted or crash landings is required to reduce the frequency of these injuries.

The potential mechanisms of hamstring strain injuries in athletes are not well understood. The study, therefore, was aimed at understanding hamstring mechanics by studying loading conditions during maximum-effort overground sprinting. Three-dimensional kinematics and ground reaction force data were collected from eight elite male sprinters sprinting at their maximum effort. Maximal isometric torques of the hip and knee were also collected. Data from the sprinting gait cycle were analyzed via an intersegmental dynamics approach, and the different joint torque components were calculated. During the initial stance phase, the ground reaction force passed anteriorly to the knee and hip, producing an extension torque at the knee and a flexion torque at the hip joint. Thus, the active muscle torque functioned to produce flexion torque at the knee and extension torque at the hip. The maximal muscle torque at the knee joint was 1.4 times the maximal isometric knee flexion torque. During the late swing phase, the muscle torque counterbalanced the motion-dependent torque and acted to flex the knee joint and extend the hip joint. The loading conditions on the hamstring muscles were similar to those of the initial stance phase. During both the initial stance and late swing phases, the large passive torques at both the knee and hip joints acted to lengthen the hamstring muscles. The active muscle torques generated mainly by the hamstrings functioned to counteract those passive effects. As a result, during sprinting or high-speed locomotion, the hamstring muscles may be more susceptible to high risk of strain injury during these two phases.

A Meta-Analysis of Soccer Injuries on Artificial Turf and Natural Grass

Directory of Open Access Journals (Sweden)

Jay H. Williams

2013-01-01

Full Text Available The goal of this investigation was to determine if playing or training on third-generation artificial turf (AT surfaces increases the incidence rate of injuries compared to natural grass (NG surfaces. This was accomplished by a meta-analysis performed on previously published research. Eight studies met the criteria of competitive soccer players, participation on both surfaces, and presentation of both exposure time and injury occurrence. Exposure time and injury incidence values were used to generate injury rate ratios (IRRs, AT/NG for all injuries as well as specific injuries. Subgroup analyses were also performed by condition (match or training, gender, and age (youth or adult. The overall IRR was 0.86 ( suggesting a lower injury risk on AT than NG. However, there was considerable heterogeneity between studies. Analyses of individual injuries and subgroups found that in many cases IRR values were significantly less than 1.0. In no case was the IRR significantly greater than 1.0. Based on this, it appears that the risk of sustaining an injury on AT under some conditions might be lowered compared to NG. However, until more is known about how issues such as altered playing styles affect injury incidence, it is difficult to make firm conclusions regarding the influence of AT on player safety.

Imaging of Spinal Cord Injury: Acute Cervical Spinal Cord Injury, Cervical Spondylotic Myelopathy, and Cord Herniation.

2016-10-01

We review the pathophysiology and imaging findings of acute traumatic spinal cord injury (SCI), cervical spondylotic myelopathy, and briefly review the much less common cord herniation as a unique cause of myelopathy. Acute traumatic SCI is devastating to the patient and the costs to society are staggering. There are currently no "cures" for SCI and the only accepted pharmacologic treatment regimen for traumatic SCI is currently being questioned. Evaluation and prognostication of SCI is a demanding area with significant deficiencies, including lack of biomarkers. Accurate classification of SCI is heavily dependent on a good clinical examination, the results of which can vary substantially based upon the patient׳s condition or comorbidities and the skills of the examiner. Moreover, the full extent of a patients׳ neurologic injury may not become apparent for days after injury; by then, therapeutic response may be limited. Although magnetic resonance imaging (MRI) is the best imaging modality for the evaluation of spinal cord parenchyma, conventional MR techniques do not appear to differentiate edema from axonal injury. Recently, it is proposed that in addition to characterizing the anatomic extent of injury, metrics derived from conventional MRI and diffusion tensor imaging, in conjunction with the neurological examination, can serve as a reliable objective biomarker for determination of the extent of neurologic injury and early identification of patients who would benefit from treatment. Cervical spondylosis is a common disorder affecting predominantly the elderly with a potential to narrow the spinal canal and thereby impinge or compress upon the neural elements leading to cervical spondylotic myelopathy and radiculopathy. It is the commonest nontraumatic cause of spinal cord disorder in adults. Imaging plays an important role in grading the severity of spondylosis and detecting cord abnormalities suggesting myelopathy. Copyright © 2016 Elsevier Inc. All rights

Mathematical Modeling of Ischemia-Reperfusion Injury and Postconditioning Therapy.

Science.gov (United States)

Fong, D; Cummings, L J

2017-11-01

Reperfusion (restoration of blood flow) after a period of ischemia (interruption of blood flow) can paradoxically place tissues at risk of further injury: so-called ischemia-reperfusion injury or IR injury. Recent studies have shown that postconditioning (intermittent periods of further ischemia applied during reperfusion) can reduce IR injury. We develop a mathematical model to describe the reperfusion and postconditioning process following an ischemic insult, treating the blood vessel as a two-dimensional channel, lined with a monolayer of endothelial cells that interact (respiration and mechanotransduction) with the blood flow. We investigate how postconditioning affects the total cell density within the endothelial layer, by varying the frequency of the pulsatile flow and the oxygen concentration at the inflow boundary. We find that, in the scenarios we consider, the pulsatile flow should be of high frequency to minimize cellular damage, while oxygen concentration at the inflow boundary should be held constant, or subject to only low-frequency variations, to maximize cell proliferation.

Full Text Available Aim: The aim of this study was to determine the pattern of midface trauma with associated concomitant injuries seen in our environment. Methodology: This was a prospective analysis of trauma patients with midfacial injuries presenting at a referral center in South West Nigeria. In addition to socio-demographic data, the following information was also obtained: Mechanism of injuries, type of midfacial injuries, concomitant/associated injuries and treatment. Results: A total of 101 patients with midfacial injuries were involved. They were made up of 85 males and 16 females. The 20-29 year age group was mostly affected (44.6% and the most common cause of midface injuries was road traffic accident (91.1%. The zygoma was fractured more than any other midfacial bone (46.0%. A total of 144 associated injuries were recorded among these patients, head and ocular injuries accounted for 49 (34% and 35 (24.3% respectively. The patients were mostly treated conservatively or by closed reduction. Conclusion: The rate of head and ocular injuries among patients with midfacial injury was high. Knowledge of these associated injuries provides useful strategies for patient care and prevention of further complications. A multidisciplinary approach is important for optimum management of these patients.

Colon trauma is frequent and its prevalence is difficult to establish because of the different factors that intervene in its origin. In Mexico, traumatic colon injuries, albeit stab wounds or gunshot wounds, are on the rise. Our objective was to evaluate the most appropriate management for traumatic colon injuries. We conducted a retrospective study of 178 case files of patients with abdominal trauma and colon lesions during a 5-year period from January 2003 to June 2008 from the General Hospital of Balbuena, Mexico City. The study compared the use of primary closure vs. colostomy, analyzing variables such as sex, age, type of wound, severity of lesion and mortality. There were a total of 178 patients; 156 were male (87.6%) and 22 were female (12.4%). The most affected age group was between 21 and 30 years; 74 patients (41.6%) had stab wounds and 104 patients (58.4%) had gunshot wounds. Management consisted mainly of primary closure in 92 cases (51.7%) vs. colostomy in 86 patients (48.3%). However, 64% of gunshot wounds were treated with colostomy. Reported mortality was 9.55% and this was due to different factors such as multiple organ injury. Treatment of traumatic colon injury should be case specific, taking into account the mechanism of the lesion, its severity and associated injuries.

Full Text Available Background: the guarantee of sporting success lies in the appropriate functioning of the musculoskeletal system, given that its vulnerability hinders the performance of each athlete. Being timely is critical to provide safe care to the affections of knee; late diagnosis in this system may lead to the development of complications and hinder sport practice. Objective: to characterize knee injuries in athletes of the sport system in the province of Cienfuegos.Methods: an observational, quantitative and qualitative, longitudinal and retrospective study was conducted. It included 104 athletes who attended the Traumatology Consultation from 2009 to 2011, presenting different types of knee injuries in various stages of training. Variables such as age, sex, sport, site of injury, stage of training, kilocalories consumed, type of training, quality of equipment and diagnosis were analyzed. The procedure used consists of a comprehensive review of case notes and medical records of all patients that attended consultation during the period analyzed, from which the necessary data was collected. Interviews with coaches and technical staff were carried out as well. Results: knee injuries occur in all ages of athletes, with a slight predominance of males. Highest frequencies are those of the ligament and meniscus, with the highest incidence in athletics, volleyball and judo. Conservative treatment predominated.Conclusions: knee injuries require a timely treatment in order to achieve athlete's success and safety.

To describe the incidence of injury in the precompetition and competition periods of the Rio 2016 Summer Paralympic Games. A total of 3657 athletes from 78 countries, representing 83.4% of all athletes at the Games, were monitored on the web-based injury and illness surveillance system over 51 198 athlete days during the Rio 2016 Summer Paralympic Games. Injury data were obtained daily from teams with their own medical support. A total of 510 injuries were reported during the 14-day Games period, with an injury incidence rate (IR) of 10.0 injuries per 1000 athlete days (12.1% of all athletes surveyed). The highest IRs were reported for football 5-a-side (22.5), judo (15.5) and football 7-a-side (15.3) compared with other sports (pGames (IR of 5.5). The shoulder was the most common anatomical area affected by injury (IR of 1.8). The data from this study indicate that (1) IRs were lower than those reported for the London 2012 Summer Paralympic Games, (2) the sports of football 5-a-side, judo and football 7-a-side were independent risk factors for injury, (3) precompetition injuries had a higher IR than competition period injuries, (4) injuries to the shoulder were the most common. These results would allow for comparative data to be collected at future editions of the Games and can be used to inform injury prevention programmes. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

To the best of our knowledge, pattern of burn injury was not reported yet at our region, our hospital considered the only tertiary referral center with the only burn unit at the region since 2001 till date, a retrospective analysis of our computerized filing system recorded 527 burn patients between 2001-2016, mean age was 26 years; 1.27:1 was the male to female ratio, 79 patients were found to have major burns, 46% of admissions were below 20 years' age, 92% was at domestic site of affection and 65% due to flame burn followed by scald burn in about 23%. The limbs were the most affected body site, majority of patients were below 15% TBSA and partial thickness, 77 patients found to have inhalational injury. Our mean hospital stay was 16 days and mortality was 8.2%. Mortality was associated with high TBSA affection, depth and flame type. This study shows the pattern of burn at north of Jordan, preventive measures by education and observation will reduce the incidence of burn and its sequel, non-flammable cook plates and stoves will probably help in decrease burn morbidity and mortality.

Liability for injury to the unborn - Recent amendments to the United Kingdom Nuclear Installations Act

International Nuclear Information System (INIS)

Coleman, J.E.

1977-01-01

The adoption in the United Kingdom in 1976 of an Act to determine liability for injury to the unborn (foetus) has provided the opportunity to amend the Nuclear Installations Act which governs the liability of nuclear operators, which is now extended to such injury. Any 'injury' attributable to a nuclear operator which so affects a mother that her child is born disabled involves the liability of that operator within the meaning of the Nuclear Installations Act whether or not either parent has suffered an injury on that occasion.

We evaluated the effects of hypo- and hyperthyroid statuses during the initial phase of skeletal muscle regeneration in rats. To induce hypo- or hyperthyroidism, adult male Wistar rats were treated with methimazole (0.03%) or T4 (10 μg/100 g), respectively, for 10 days. Three days before sacrifice, a crush injury was produced in the solear muscles of one half of the animals, while the other half remained intact. T3, T4, TSH, and leptin serum levels were not affected by the injury. Serum T3 and T4 levels were significantly increased in hyperthyroid and hyper-injury animals. Hypothyroidism was confirmed by the significant increase in serum TSH levels in hypothyroid and hypo-injury animals. Injury increased cell infiltration and macrophage accumulation especially in hyperthyroid animals. Both type 2 and type 3 deiodinases were induced by lesion, and the opposite occurred with the type 1 isoform, at least in the control and hyperthyroid groups. Injury increased both MyoD and myogenin expression in all the studied groups, but only MyoD expression was increased by thyroidal status only at the protein level. We conclude that thyroid hormones modulate skeletal muscle regeneration possibly by regulating the inflammatory process, as well as MyoD and myogenin expression in the injured tissue.

2012-09-01

The current study explores sentence comprehension impairments among adults following moderate closed head injury. It was hypothesized that if the factor of syntactic complexity significantly affects sentence comprehension in these patients, it would testify to the existence of syntactic processing deficit along with working-memory problems. Thirty-six adults (18 closed head injury patients and 18 healthy controls matched in age, gender, and IQ) participated in the study. A picture-sentence matching task together with various tests for memory, language, and reading abilities were used to explore whether sentence comprehension impairments exist as a result of a deficit in syntactic processing or of working-memory dysfunction. Results indicate significant impairment in sentence comprehension among adults with closed head injury compared with their non-head-injured peers. Results also reveal that closed head injury patients demonstrate considerable decline in working memory, short-term memory, and semantic knowledge. Analysis of the results shows that memory impairment and syntactic complexity contribute significantly to sentence comprehension difficulties in closed head injury patients. At the same time, the presentation mode (spoken or written language) was found to have no effect on comprehension among adults with closed head injury, and their reading abilities appear to be relatively intact.

Exploring Driver Injury Severity at Intersection: An Ordered Probit Analysis

Directory of Open Access Journals (Sweden)

Yaping Zhang

2015-02-01

Full Text Available It is well known that intersections are the most hazardous locations; however, only little is known about driver injury severity in intersection crashes. Hence, the main goal of this study was to further examine the different factors contributing to driver injury severity involved in fatal crashes at intersections. Data used for the present analysis was from the US DOT-Fatality Analysis Reporting System (FARS crash database from the year 2011. An ordered probit model was employed to fit the fatal crash data and analyze the factors impacting each injury severity level. The analysis results displayed that driver injury severity is significantly affected by many factors. They include driver age and gender, driver ethnicity, vehicle type and age (years of use, crash type, driving drunk, speeding, violating stop sign, cognitively distracted driving, and seat belt usage. These findings from the current study are beneficial to form a solid basis for adopting corresponding measures to effectively drop injury severity suffering from intersection crash. More insights into the effects of risk factors on driver injury severity could be acquired using more advanced statistical models.

Clèries, Montse; Bosch, Anna; Vela, Emili; Bustins, Montse

2015-09-01

To verify the usefulness of the minimum data set (MDS) for acute-care hospitals and emergency resources for the study of road traffic injuries and to describe the use of health resources in Catalonia (Spain). The study population consisted of patients treated in any kind of emergency service and patients admitted for acute hospitalization in Catalonia in 2013. A descriptive analysis was performed by age, gender, time and clinical variables. A total of 48,150 patients were treated in hospital emergency departments, 6,210 were attended in primary care, and 4,912 were admitted to hospital. There was a higher proportion of men (56.2%), mainly aged between 20 and 40 years. Men accounted for 54.9% of patients with minor injuries and 75.1% of those with severe injuries. Contusions are the most common injury (30.2%), followed by sprains (28.7%). Fractures mostly affected persons older than 64 years, internal injuries particularly affected men older than 64 years, and wounds mainly affected persons younger than 18 years and older than 64 years. In the adult population, the severity of the injuries increased with age, leading to longer length of stay and greater complexity. Hospital mortality was 0.2%. Fractures, internal injuries and wounds were more frequent in the group of very serious injuries, and sprains and contusions in the group of minor injuries. MDS records (acute hospitals and emergency resources) provide information that is complementary to other sources of information on traffic accidents, increasing the completeness of the data.

Venegoni, Whitney; Shen, Qiuhua; Thimmesch, Amanda R; Bell, Meredith; Hiebert, John B; Pierce, Janet D

2017-06-01

The aim of this study was to discuss secondary traumatic brain injury, the mitochondria and the use of antioxidants as a treatment. One of the leading causes of death globally is traumatic brain injury, affecting individuals in all demographics. Traumatic brain injury is produced by an external blunt force or penetration resulting in alterations in brain function or pathology. Often, with a traumatic brain injury, secondary injury causes additional damage to the brain tissue that can have further impact on recovery and the quality of life. Secondary injury occurs when metabolic and physiologic processes alter after initial injury and includes increased release of toxic free radicals that cause damage to adjacent tissues and can eventually lead to neuronal necrosis. Although antioxidants in the tissues can reduce free radical damage, the magnitude of increased free radicals overwhelms the body's reduced defence mechanisms. Supplementing the body's natural supply of antioxidants, such as coenzyme Q10, can attenuate oxidative damage caused by reactive oxygen species. Discussion paper. Research literature published from 2011-2016 in PubMed, CINAHL and Cochrane. Prompt and accurate assessment of patients with traumatic brain injury by nurses is important to ensure optimal recovery and reduced lasting disability. Thus, it is imperative that nurses be knowledgeable about the secondary injury that occurs after a traumatic brain injury and aware of possible antioxidant treatments. The use of antioxidants has potential to reduce the magnitude of secondary injury in patients who experience a traumatic brain injury. © 2017 John Wiley & Sons Ltd.

Injuries to the foot in athletes are often subtle and can lead to a substantial loss of function if not diagnosed and treated appropriately. For these injuries in general, even after a diagnosis is made, treatment options are controversial and become even more so in high level athletes where limiting the time away from training and competition is a significant consideration. In this review, we cover some of the common and important sporting injuries affecting the foot including updates on their management and outcomes.

In southern Brazil, the recent increase in tropospheric ozone (O 3 ) concentrations poses an additional threat to the biodiverse but endangered and fragmented remnants of the Atlantic Forest. Given the mostly unknown sensitivity of tropical species to oxidative stress, the principal objective of this study was to determine whether the current O 3 levels in the Metropolitan Region of Campinas (MRC), downwind of São Paulo, affect the native vegetation of forest remnants. Foliar responses to O 3 of three tree species typical of the MRC forests were investigated using indoor chamber exposure experiments under controlled conditions and a field survey. Exposure to 70ppb O 3 reduced assimilation and leaf conductance but increased respiration in Astronium graveolens while gas exchange in Croton floribundus was little affected. Both A. graveolens and Piptadenia gonoacantha developed characteristic O 3 -induced injury in the foliage, similar to visible symptoms observed in >30% of trees assessed in the MRC, while C. floribundus remained asymptomatic. The underlying structural symptoms in both O 3 -exposed and field samples were indicative of oxidative burst, hypersensitive responses, accelerated cell senescence and, primarily in field samples, interaction with photo-oxidative stress. The markers of O 3 stress were thus mostly similar to those observed in other regions of the world. Further research is needed, to estimate the proportion of sensitive forest species, the O 3 impact on tree growth and stand stability and to detect O 3 hot spots where woody species in the Atlantic Forest are mostly affected.

Self-Reported Minimalist Running Injury Incidence and Severity: A Pilot Study.

Science.gov (United States)

Ostermann, Katrina; Ridpath, Lance; Hanna, Jandy B

2016-08-01

Minimalist running entails using shoes with a flexible thin sole and is popular in the United States. Existing literature disagrees over whether minimalist running shoes (MRS) improve perceived severity of injuries associated with running in traditional running shoes (TRS). Additionally, the perceived injury patterns associated with MRS are relatively unknown. To examine whether injury incidence and severity (ie, degree of pain) by body region change after switching to MRS, and to determine if transition times affect injury incidences or severity with MRS. Runners who were either current or previous users of MRS were recruited to complete an Internet-based survey regarding self-reported injury before switching to MRS and whether self-reported pain from that injury decreased after switching. Questions regarding whether new injuries developed in respondents after switching to MRS were also included. Analyses were calculated using t tests, Wilcoxon signed rank tests, and Fischer exact tests. Forty-seven runners completed the survey, and 16 respondents reported injuries before switching to MRS. Among these respondents, pain resulting from injuries of the feet (P=.03) and knees (P=.01) decreased. Eighteen respondents (38.3%) indicated they sustained new injuries after switching to MRS, but the severity of these did not differ significantly from no injury. Neither time allowed for transition to MRS nor use or disuse of a stretching routine during this period was correlated with an increase in the incidence or severity of injuries. After switching to MRS, respondents perceived an improvement in foot and knee injuries. Additionally, respondents using MRS reported an injury rate of 38.3%, compared with the approximately 64% that the literature reports among TRS users. Future studies should be expanded to determine the full extent of the differences in injury patterns between MRS and TRS.

Uremia does not affect neointima formation in mice

Aarup, Annemarie; Nielsen, Carsten H; Bisgaard, Line S

2017-01-01

Atherosclerotic cardiovascular disease is a major complication of chronic kidney disease (CKD). CKD leads to uremia, which modulates the phenotype of aortic smooth muscle cells (SMCs). Phenotypic modulation of SMCs plays a key role in accelerating atherosclerosis. We investigated the hypothesis...... that uremia potentiates neointima formation in response to vascular injury in mice. Carotid wire injury was performed on C57BL/6 wt and apolipoprotein E knockout (Apoe-/-) mice two weeks after induction of uremia by 5/6 nephrectomy. Wire injury led to neointima formation and downregulation of genes encoding...... classical SMC markers (i.e., myocardin, α-smooth muscle actin, SM22-alpha, and smooth muscle myosin heavy chain) in both wt and Apoe-/-mice. Contrary to our expectations, uremia did not potentiate neointima formation, nor did it affect intimal lesion composition as judged from magnetic resonance imaging...

Dietrich, William Dalton; Cappuccino, Andrew; Cappuccino, Helen

2011-01-01

Spinal cord injury is a devastating condition that affects approximately 12,000 patients each year in the United States. Major causes for spinal cord injury include motor vehicle accidents, sports-related injuries, and direct trauma. Moderate hypothermia has gained attention as a potential therapy due to recent experimental and clinical studies and the use of modest systemic hypothermia (MSH) in high profile case of spinal cord injury in a National Football League (NFL) player. In experimental models of spinal cord injury, moderate hypothermia has been shown to improve functional recovery and reduce overall structural damage. In a recent Phase I clinical trial, systemic hypothermia has been shown to be safe and provide some encouraging results in terms of functional recovery. This review will summarize recent preclinical data, as well as clinical findings that support the continued investigations for the use of hypothermia in severe cervical spinal cord injury.

Full Text Available Based on what you found during the eye examination, classify the injury as a non-mechanical injury (chemical or thermal injury, a non-globe injury (orbital or adnexal injury or as a mechanical globe injury. In the case of mechanical globe injuries, it is important to classify the injury according to the Birmingham Eye Trauma Terminology System (BETTS and write it down in the patient’s notes; this will help to ensure that everyone involved in caring for the patient will have a consistent understanding of the type of injury. The resulting uniformity of terminology also helps with research, making it possible to compare data and do audits of injuries – which is essential for prevention.

Full Text Available BackgroundPeriventricular leukomalacia (PVL is the most common form of preterm brain injury affecting the cerebral white matter. This type of injury involves a multiphase process and is induced by many factors, including hypoxia–ischemia (HI and infection. Previous studies have suggested that lymphocytes play a significant role in the pathogenesis of brain injury, and the aim of this study was to determine the contribution of lymphocyte subsets to preterm brain injury.MethodsImmunohistochemistry on brain sections from neonatal mice was performed to evaluate the extent of brain injury in wild-type and T cell and B cell-deficient neonatal mice (Rag1−/− mice using a mouse model of HI-induced preterm brain injury. Flow cytometry was performed to determine the presence of different types of immune cells in mouse brains following HI. In addition, immunostaining for CD3 T cells and CD20 B cells was performed on postmortem preterm human infant brains with PVL.ResultsMature lymphocyte-deficient Rag1−/− mice showed protection from white matter loss compared to wild type mice as indicated by myelin basic protein immunostaining of mouse brains. CD3+ T cells and CD20+ B cells were observed in the postmortem preterm infant brains with PVL. Flow cytometry analysis of mouse brains after HI-induced injury showed increased frequency of CD3+ T, αβT and B cells at 7 days after HI in the ipsilateral (injured hemisphere compared to the contralateral (control, uninjured hemisphere.ConclusionLymphocytes were found in the injured brain after injury in both mice and humans, and lack of mature lymphocytes protected neonatal mice from HI-induced brain white matter injury. This finding provides insight into the pathology of perinatal brain injury and suggests new avenues for the development of therapeutic strategies.

It is known that some people can, and do, sustain >1 injury over a playing season. However, there is currently little high-quality epidemiological evidence about the risk of, and relationships between, multiple and subsequent injuries. To describe the subsequent injuries sustained by Australian Football League (AFL) players over 1 season, including their most common injury diagnoses. Cohort study; Level of evidence, 3. Within-player linked injury data on all date-ordered match-loss injuries sustained by AFL players during 1 full season were obtained. The total number of injuries per player was determined, and in those with >1 injury, the Subsequent Injury Classification (SIC) model was used to code all subsequent injuries based on their Orchard Sports Injury Classification System (OSICS) codes and the dates of injury. There were 860 newly recorded injuries in 543 players; 247 players (45.5%) sustained ≥1 subsequent injuries after an earlier injury, with 317 subsequent injuries (36.9% of all injuries) recorded overall. A subsequent injury generally occurred to a different body region and was therefore superficially unrelated to an index injury. However, 32.2% of all subsequent injuries were related to a previous injury in the same season. Hamstring injuries were the most common subsequent injury. The mean time between injuries decreased with an increasing number of subsequent injuries. When relationships between injuries are taken into account, there is a high level of subsequent (and multiple) injuries leading to missed games in an elite athlete group.

2013-02-01

The recreational and competitive practice of acrobatic sports, that is, trampoline, tumbling and acrobatic gymnastics (ACRO), is growing rapidly around the world. Many studies described the injuries affecting young artistic gymnasts, but only few concerned acrobatic sports. During a 5-year period, 357 traumatic events were collected in young acrobats practicing trampoline, tumbling or ACRO. Accident characteristics, level of expertise and training, injury location (upper limb, spine and lower limb), type of tissue injured (bone, cartilage, muscle, ligament and tendon) and provoking factors (intrinsic/behavioural and extrinsic) were investigated. Acrobats of national and international levels were mostly injured. Injuries occurring in acrobatic sports concerned predominantly the lower limbs and concerned in this body part mainly damages to ligaments. Forearm and knee injuries were preferentially related to trampoline. Ankle injuries were preferentially related to tumbling. Wrist injuries were preferentially related to ACRO. Upper limb bone damage and upper limb tendon damage were preferentially related to trampoline and ACRO, respectively. Intrinsic/behavioural factors were the main injury determinant in the three acrobatic sports. The main injuries in acrobatic sports (i.e. lower limbs) are similar to those observed in artistic gymnastics. Specific injuries may result from falls and incomplete and/or erroneous figure's landing and may also depend to the type of the landing surface. II.

This study aimed to record and analyse incidence and characteristics of injuries and illnesses incurred during the Indoor Athletics Championships. During the 2011 European Indoor Athletics Championships in Paris, incidence and characteristics of new injuries and illnesses were recorded prospectively by physicians and physiotherapists from national teams and local organizing committee in 631 registered athletes. Around 70% of athletes were covered by the medical teams (response rate: 84%). Thirty injuries, including eight time-loss injuries, were reported, representing an incidence of 47.5 injuries and 29.4 time-loss injuries per 1000 registered athletes. Injury and time-loss injury risk were highest in heptathlon and hurdles. Three-quarters of injuries affected the lower extremity. Thigh strain was the most common diagnosis (n = 7; 23%). Noncontact trauma (n = 9; 30%) was the predominant cause. A total of 18 illnesses were reported. Incidence of illnesses was 28.5 per 1000 registered athletes, with 17% resulting in time lost from sport. Upper respiratory tract infection was the most common diagnosis (n = 8; 44%) followed by upper respiratory tract allergy (n = 3; 17%) and gastroenteritis (n = 3; 17%). Injury and illness incidence and severity were lower during the 2011 European Indoor Athletics Championships than during outdoor championships, probably due to the shorter duration, the fewer number of events, and shorter sprint distances. © 2012 John Wiley & Sons A/S.

To describe injury patterns of skateboard-associated injuries (SAIs) and to assess the frequency and severity of SAIs depending on an athlete's skateboarding experience. Cross-sectional observation. Skating areas. A total of 100 Viennese skateboarders. No intervention. The participants filled in a questionnaire that was used to assess selected sociodemographic data; duration and frequency of skateboarding; "stance"; and localization, rate, as well as the severity of SAIs during the past 24 months. Skating behavior and sociodemographic data were compared with frequency and severity of SAIs. Response rate of questionnaires was 75% (n=75) of the participants. Duration of skateboarding was 8+/-5 years, and training time was 18+/-11 hours/week. A total of 97% (73) of the respondents reported at least one injury: in 52% (39) of the respondents the most serious injury was mild to moderate (laceration, contusion, strain/sprain, and bruise), whereas in 45% (34) it was severe (ligament rupture, fracture). A total of 33% (13) of participants experiencing only mild-to-moderate injuries consulted a physician compared with 94% (32) with at least one serious injury. The most severely affected regions were lower leg/ankle/foot in 32% (24) of all respondents who experienced at least one severe injury and forearm/wrist/hand in 16% (12) who experienced at least one severe injury. Only 13% (10) used protective equipment. Multivariate logistic regression for the occurrence of at least one severe injury with all socioeconomic and sport-relevant data investigated revealed significant positive correlations with weekly training time (P=.037) and years of experience (P=.021). However, after correcting for multiple testing (Bonferroni adjustment for 8 tests), no significances remained. More experienced skateboarders seem to have a greater risk of incurring severe SAIs, but sociodemographic factors seem to have no influence on injury risk in this population. Only a minority of skateboarders

ABSTRACT Purpose The potential mechanisms of hamstring strain injuries in athletes are not well understood. The study, therefore, was aimed at understanding hamstring mechanics by studying loading conditions during maximum-effort overground sprinting. Methods Three-dimensional kinematics and ground reaction force data were collected from eight elite male sprinters sprinting at their maximum effort. Maximal isometric torques of the hip and knee were also collected. Data from the sprinting gait cycle were analyzed via an intersegmental dynamics approach, and the different joint torque components were calculated. Results During the initial stance phase, the ground reaction force passed anteriorly to the knee and hip, producing an extension torque at the knee and a flexion torque at the hip joint. Thus, the active muscle torque functioned to produce flexion torque at the knee and extension torque at the hip. The maximal muscle torque at the knee joint was 1.4 times the maximal isometric knee flexion torque. During the late swing phase, the muscle torque counterbalanced the motion-dependent torque and acted to flex the knee joint and extend the hip joint. The loading conditions on the hamstring muscles were similar to those of the initial stance phase. Conclusions During both the initial stance and late swing phases, the large passive torques at both the knee and hip joints acted to lengthen the hamstring muscles. The active muscle torques generated mainly by the hamstrings functioned to counteract those passive effects. As a result, during sprinting or high-speed locomotion, the hamstring muscles may be more susceptible to high risk of strain injury during these two phases. PMID:24911288

Context: Injuries are a major adverse event in a soccer player's career. Reducing injury incidence requires a thorough knowledge of the epidemiology of soccer injuries. Objective: To investigate the incidence and characteristics of injuries in the Dutch premier soccer league. Design: Cohort study. Setting: The Dutch premier soccer league. Patients or Other Participants: During the 2009–2010 soccer season, a total of 217 professional soccer players from 8 teams were prospectively followed. Main Outcome Measure(s): The medical staff recorded time-loss injuries, including information on injuries (ie, type, body part, duration) and exposure data for training sessions and matches. Results: A total of 286 injuries were recorded, affecting 62.7% of the players. The overall injury incidence was 6.2 injuries per 1000 player-hours, 2.8 in training sessions and 32.8 in matches. Most of the recorded injuries were acute (68.5%). Eight percent of the injuries were classified as recurrent. Injuries were most likely to be located in the lower extremities (82.9%). Injury time loss ranged from 1 to 752 days, with a median of 8 days. Knee injuries had the greatest consequences in terms of days of absence from soccer play (on average, 45 days). The most common diagnosis was muscle/tendon injury of the lower extremities (32.9%). Conclusions: Injury risk in the Dutch premier soccer league is high, especially during matches. Preventive measures should focus on the most common diagnoses, namely, muscle/tendon injuries of the lower extremities. PMID:25531144

Purpose To determine the prevalence of and risk factors for needlesticks in interventional radiology physicians, as well as the attitudes, behaviors, and conditions that promote or interfere with reporting of these injuries. Materials and Methods A total of 3889 interventional radiologists from academic and private practice in the United States were surveyed by emailing all interventional radiologist members of the Society of Interventional Radiology, including attending-level physicians and trainees (April-August 2016). The institutional review board waived the need for consent. Questions inquired about the nature, frequency, and type of needlestick and sharps injuries and whether and to whom these incidents were reported. Stepwise regression was used to determine variables predicting whether injuries were reported. Results In total, 908 (23%) interventional radiologists completed at least a portion of the survey. Eight hundred fourteen (91%) of 895 respondents reported a prior needlestick injury, 583 (35%) of 895 reported at least one injury while treating an HIV-positive patient, and 626 (71%) of 884 reported prior training regarding needlestick injury. There was, on average, one needlestick for every 5 years of practice. Most needlestick or sharps injuries were self inflicted (711 [87%] of 817) and involved a hollow-bore device (464 [56%] of 824). Only 566 (66%) of 850 injuries were reported. The most common reasons for not reporting included perceived lack of utility of reporting (79 [28%] of 282), perceived low risk for injury (56 [20%] of 282), noncontaminated needle (53 [19%] of 282), too-lengthy reporting process (37 [13%] of 282), and associated stigma (23 [8%] of 282). Only 156 (25%) of 624 respondents informed their significant other. Stepwise regression assessing variables affecting the likelihood of reporting showed that male sex (P = .009), low-risk patient (P < .0001), self injury (P = .010), trainee status (P < .0001), and the total number of prior

The ribs are frequently affected by blunt or penetrating injury to the thorax. In the emergency department setting, it is vital for the interpreting radiologist to not only identify the presence of rib injuries but also alert the clinician about organ-specific injury, specific traumatic patterns, and acute rib trauma complications that require emergent attention. Rib injuries can be separated into specific morphologic fracture patterns that include stress, buckle, nondisplaced, displaced, segmental, and pathologic fractures. Specific attention is also required for flail chest and for fractures due to pediatric nonaccidental trauma. Rib fractures are associated with significant morbidity and mortality, both of which increase as the number of fractured ribs increases. Key complications associated with rib fracture include pain, hemothorax, pneumothorax, extrapleural hematoma, pulmonary contusion, pulmonary laceration, acute vascular injury, and abdominal solid-organ injury. Congenital anomalies, including supernumerary or accessory ribs, vestigial anterior ribs, bifid ribs, and synostoses, are common and should not be confused with traumatic pathologic conditions. Nontraumatic mimics of traumatic rib injury, with or without fracture, include metastatic disease, primary osseous neoplasms (osteosarcoma, chondrosarcoma, Ewing sarcoma, Langerhans cell histiocytosis, and osteochondroma), fibrous dysplasia, and Paget disease. Principles of management include supportive and procedural methods of alleviating pain, treating complications, and stabilizing posttraumatic deformity. By recognizing and accurately reporting the imaging findings, the radiologist will add value to the care of patients with thoracic trauma.

BACKGROUND: Homeless people have elevated mortality, especially due to external causes. We aimed to examine suicide and unintentional injury mortality levels and identify predictors in the homeless population. METHODS: A nationwide, register-based cohort study of homeless people aged 16 years...... and older was carried out using the Danish Homeless Register, 1999-2008. RESULTS: In all, 32 010 homeless people (70.5% men) were observed. For men, the mortality rate was 174.4 [95% confidence interval (CI) = 150.6-198.1] per 100 000 person-years for suicide and 463.3 (95% CI = 424.......6-502.0) for unintentional injury. For women, the corresponding rates were 111.4 (95% CI = 81.7-141.1) for suicide and 241.4 (95% CI = 197.6-285.1) for unintentional injury. Schizophrenia spectrum, affective, personality and substance use disorders were strongly associated with increased risk of suicide; the highest risk...

Time-Dependent Gene Profiling Indicates the Presence of Different Phases for Ischemia/Reperfusion Injury in Retina

2014-01-01

Full Text Available Ischemia/reperfusion (IR injury has been associated with several retinal pathologies, and a few genes/gene products have been linked to IR injury. However, the big picture of temporal changes, regarding the affected gene networks, pathways, and processes remains to be determined. The purpose of the present study was to investigate initial, intermediate, and later stages to characterize the etiology of IR injury in terms of the pathways affected over time. Analyses indicated that at the initial stage, 0-hour reperfusion following the ischemic period, the ischemia-associated genes were related to changes in metabolism. In contrast, at the 24-hour time point, the signature events in reperfusion injury include enhanced inflammatory and immune responses as well as cell death indicating that this would be a critical period for the development of any interventional therapeutic strategies. Genes in the signal transduction pathways, particularly transmitter receptors, are downregulated at this time. Activation of the complement system pathway clearly plays an important role in the later stages of reperfusion injury. Together, these results demonstrate that the etiology of injury related to IR is characterized by the appearance of specific patterns of gene expression at any given time point during retinal IR injury. These results indicate that evaluation of treatment strategies with respect to time is very critical.

Impact direction effect on serious-to-fatal injuries among drivers in near-side collisions according to impact location: focus on thoracic injuries.

Occupant injury in real world vehicle accidents can be significantly affected by a set of crash characteristics, of which impact direction and impact location (or damage location) in general scale interval (e.g., frontal impact is frequently defined as general damage to vehicle frontal end with impact angle range of 11-1 o'clock) have been identified to associate with injury outcome. The effects of crash configuration in more specific scale of interval on the injury characteristics have not been adequately investigated. This paper presents a statistical analysis to investigate the combined effects of specific impact directions and impact locations on the serious-to-fatal injuries of driver occupants involved in near-side collisions using crash data from National Automotive Sampling System-Crashworthiness Data System (NASS-CDS) for the calendar years of 1995-2005. The screened injury dataset is categorized by three impact locations (side front, side center and side distributed) and two impact directions (oblique impact at 10 o'clock and pure lateral impact at 9 o'clock), resulting in six crash configurations in total. The weighted counts and the risks of different types of injuries in each subgroup are calculated, with which the relative risks along with 95% confidence intervals under oblique impacts versus lateral impacts in each impact location category are computed. Accordingly, the most frequent injury patterns, the risks and the coded-sources of serious thoracic injuries in different crash configurations are identified. The approach adopted in the present study provides new perspectives into occupant injury outcomes and associated mechanism. Results of the analyses reveal the importance of consideration of the crash configurations beyond the scope of existing side-impact regulatory tests and stress the necessity of vehicle crashworthiness and restraint system design in omni-direction to better protect occupants in real-world crash scenarios.

Purpose: Accommodative spasm, which manifests as ciliary muscle spasm, convergent strabismus or miosis, is a recognised consequence of head trauma. In whiplash cases, cervical spine hyperextension poses a risk of contra-coup injury and brainstem trauma, and is known to affect the visual system. However, to date, no cases of accommodative spasm due to whiplash injury have been reported. Observations: We present the case of a 34-year-old female who developed sudden onset blurred distance vis...

Injuries of the medial epicondyle are relatively common, mostly affecting children between 7 and 15 years. The anatomical characteristics of this apophysis can make diagnosis difficult in minimally displaced fractures. In a small percentage of cases, the fractured fragment may occupy the retroepitrochlear groove. The presence of dysesthesias in the territory of the ulnar nerve requires urgent open reduction of the incarcerated fragment. A case of a seven-year-old male patient is presented, who required surgical revision due to a displaced medial epicondyle fracture associated with ulnar nerve injury. A review of the literature is also made. Copyright © 2013 SECOT. Published by Elsevier Espana. All rights reserved.

Research progress of immune tolerance in the treatment of brain injury

Directory of Open Access Journals (Sweden)

Hua YAN

2014-08-01

Full Text Available Due to its special anatomical structures and immune pathophysiological mechanisms, brain damage repair is greatly different from damage repair of other systems. Secondary brain injury and inflammation are closely related. As a "double-edged sword", inflammation scavenges hazardous substances on the early stage of injury, but has side effects on normal brain tissue. The use of immunosuppressive therapy or hypothermia can inhibit immune injury, but the presence of reduced immunity may result in infection and tumorigenesis in the long term. Only reducing the autoimmune attack against brain tissue without affecting other immune capacity of the body will be optimized solution, and this paper will make a review on the research of immune tolerance in the treatment of brain injury with optimized program. doi: 10.3969/j.issn.1672-6731.2014.08.017

Scientific injury data in men's professional team handball injuries are rare and even less scientific information exists on injury prevention. In 2011, Germany's national second team handball league was restructured by merging the existing two regional leagues into one league. This study evaluates the injury patterns in professional team handball and compares the injury rates between the first and second league before and after the restructure. All players of Germany's national first and second men's team handball leagues have mandatory trauma insurance with the same insurance company. This retrospective cohort study analysed the injury data of three consecutive seasons 2010-2013 using standardized injury definitions. 1194 professional team handball players were included in this study. The majority of severe injuries affected the lower extremities, shoulders, and hands. The average injury incidence significantly differed between the first (4.9 injuries per 1000 h) and the second league (3.9 per 1000 h, p handball league and presents details on prevalence, incidence, and patterns of injury in professional men's team handball. This study is an important basis for developing injury prevention strategies that should focus on the shoulders, hands, and lower extremities and on reducing the number of matches and travel burden.

Drosophila Insulin receptor regulates the persistence of injury-induced nociceptive sensitization

2018-01-01

ABSTRACT Diabetes-associated nociceptive hypersensitivity affects diabetic patients with hard-to-treat chronic pain. Because multiple tissues are affected by systemic alterations in insulin signaling, the functional locus of insulin signaling in diabetes-associated hypersensitivity remains obscure. Here, we used Drosophila nociception/nociceptive sensitization assays to investigate the role of Insulin receptor (Insulin-like receptor, InR) in nociceptive hypersensitivity. InR mutant larvae exhibited mostly normal baseline thermal nociception (absence of injury) and normal acute thermal hypersensitivity following UV-induced injury. However, their acute thermal hypersensitivity persists and fails to return to baseline, unlike in controls. Remarkably, injury-induced persistent hypersensitivity is also observed in larvae that exhibit either type 1 or type 2 diabetes. Cell type-specific genetic analysis indicates that InR function is required in multidendritic sensory neurons including nociceptive class IV neurons. In these same nociceptive sensory neurons, only modest changes in dendritic morphology were observed in the InRRNAi-expressing and diabetic larvae. At the cellular level, InR-deficient nociceptive sensory neurons show elevated calcium responses after injury. Sensory neuron-specific expression of InR rescues the persistent thermal hypersensitivity of InR mutants and constitutive activation of InR in sensory neurons ameliorates the hypersensitivity observed with a type 2-like diabetic state. Our results suggest that a sensory neuron-specific function of InR regulates the persistence of injury-associated hypersensitivity. It is likely that this new system will be an informative genetically tractable model of diabetes-associated hypersensitivity. PMID:29752280

We conducted a study on the risk for foot and ankle injuries in college football players on the basis of injury type and player position. In February 2006, we evaluated 320 intercollegiate football players at the National Football League Combine. All pathologic conditions and surgical procedures of the foot and ankle were recorded, and data were analyzed by player position to detect any trends. Seventy-two percent (n = 231) of the players had a history of foot and ankle injuries, with a total of 287 foot and ankle injuries (1.24 injuries/player injured). The most common injuries were lateral ankle sprain (n = 115), syndesmotic sprain (50), metatarsophalangeal dislocation/turf toe (36), and fibular fracture (25). Foot and ankle injuries were most common in kickers/punters (100% incidence), special teams (100%), running backs (83%), wide receivers (83%), and offensive linemen (80%). Lateral ankle sprains, the most common injuries, were treated surgically only 2.6% of the time. Offensive linemen were most likely to have had syndesmotic sprains (32%), and quarterbacks had the highest incidence of fibular fractures (16%). Foot and ankle injuries are common in collegiate football players, affecting 72% of players. Thirteen percent underwent surgical treatment. Trends are seen in the types of injuries for the different player positions.

There is an increased risk of orofacial injuries in swimming pool facilities. Nevertheless, only a few studies have addressed this issue. The aim of this study was to identify the frequency of lip and tooth injuries at public swimming pools in Austria. A further aim was to examine which gender and age groups were affected, where and why these injuries occurred, and whether pool attendants had sufficient knowledge of dental first-aid measures. A total of 764 pool attendants in Austria were contacted by telephone and 689 participated in the study (90.2%). The attendants were interviewed retrospectively about accident occurrences in 2014 by a standardized questionnaire. Responses to the provision of first aid and choice of storage medium for avulsed teeth were subsequently evaluated. The frequency of lip injuries was 19.0%, and tooth injuries were 11.3%. Male bathers (P < .05) and children under 12 years (P < .001) most frequently suffered injuries. The waterslide was the most common accident site. The most common cause of lip injuries was slipping on wet surfaces (39.0%), and for tooth injuries it was collisions with other persons or objects (each 28.1%). The pool attendants' responses were predominantly good or sufficient on first aid, with the exception of what storage medium to choose. Tooth rescue boxes were available in only 8.6% of all pool facilities. Orofacial injuries are a frequently occurring problem in swimming pool facilities. The pool attendants' knowledge on first-aid care of tooth injuries could still be improved. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Horseback riding is more dangerous than motorcycle riding, skiing, football, and rugby. The purpose of this study was to identify the incidence and injury patterns, as well as risk factors associated with severe equestrian trauma. All patients with major equestrian injuries (injury severity score > or = 12) admitted between 1995 and 2005 were reviewed. A 46-question survey outlining potential rider, animal, and environmental risk factors was administered. Among 7941 trauma patients, 151 (2%) were injured on horseback (mean injury severity score, 20; mortality rate, 7%). Injuries included the chest (54%), head (48%), abdomen (22%), and extremities (17%). Forty-five percent required surgery. Survey results (55%) indicated that riders and horses were well trained, with a 47% recidivism rate. Only 9% of patients wore helmets, however, 64% believed the accident was preventable. Chest trauma previously has been underappreciated. This injury pattern may be a result of significant rider experience. Helmet and vest use will be targeted in future injury prevention strategies.

Nonlinear Dynamic Theory of Acute Cell Injuries and Brain Ischemia

Taha, Doaa; Anggraini, Fika; Degracia, Donald; Huang, Zhi-Feng

2015-03-01

Cerebral ischemia in the form of stroke and cardiac arrest brain damage affect over 1 million people per year in the USA alone. In spite of close to 200 clinical trials and decades of research, there are no treatments to stop post-ischemic neuron death. We have argued that a major weakness of current brain ischemia research is lack of a deductive theoretical framework of acute cell injury to guide empirical studies. A previously published autonomous model based on the concept of nonlinear dynamic network was shown to capture important facets of cell injury, linking the concept of therapeutic to bistable dynamics. Here we present an improved, non-autonomous formulation of the nonlinear dynamic model of cell injury that allows multiple acute injuries over time, thereby allowing simulations of both therapeutic treatment and preconditioning. Our results are connected to the experimental data of gene expression and proteomics of neuron cells. Importantly, this new model may be construed as a novel approach to pharmacodynamics of acute cell injury. The model makes explicit that any pro-survival therapy is always a form of sub-lethal injury. This insight is expected to widely influence treatment of acute injury conditions that have defied successful treatment to date.

Weight-training injuries. Common injuries and preventative methods.

Mazur, L J; Yetman, R J; Risser, W L

1993-07-01

The use of weights is an increasingly popular conditioning technique, competitive sport and recreational activity among children, adolescents and young adults. Weight-training can cause significant musculoskeletal injuries such as fractures, dislocations, spondylolysis, spondylolisthesis, intervertebral disk herniation, and meniscal injuries of the knee. Although injuries can occur during the use of weight machines, most apparently happen during the aggressive use of free weights. Prepubescent and older athletes who are well trained and supervised appear to have low injury rates in strength training programmes. Good coaching and proper weightlifting techniques and other injury prevention methods are likely to minimise the number of musculoskeletal problems caused by weight-training.

2015-10-01

Orthopedic injuries commonly affect children during earthquakes, but reports about them are rare. This setting may lead to different standards of care, but guidelines are still missing in this field. A systematic review was performed to: (1) assess type and body distribution of pediatric earthquake-related injuries, treatment performed, length of stay, and complications; and (2) identify starting points to define standards of care. PubMed database was researched for papers (1999-2014 period) in agreement with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Inclusion criteria were: English, French, Spanish, or Italian language and data reported about orthopedic lesions in children (≤18 years old). Reviews, letters, commentaries, editorials, and single case reports were excluded. Two independent reviewers selected articles after abstract and full-text reading. Traumatic injuries caused child hospital admissions ranging from 46.9% to 100.0%; 16% to 53% suffered fractures. Lower limbs mostly were involved. Soft-tissue injuries affected 55% of patients. Debridement and external fixation (EF) were the most frequent surgical treatments. Amputation rates varied from 5% to 11%. This study revealed that field hospitals should be prepared to: (1) treat mainly lower extremities fractures in children; and (2) use especially EF techniques. The presence of orthopedic surgeons familiar with pediatric traumatology should be considered.

Heading and head injuries in soccer.

Science.gov (United States)

Kirkendall, D T; Jordan, S E; Garrett, W E

2001-01-01

In the world of sports, soccer is unique because of the purposeful use of the unprotected head for controlling and advancing the ball. This skill obviously places the player at risk of head injury and the game does carry some risk. Head injury can be a result of contact of the head with another head (or other body parts), ground, goal post, other unknown objects or even the ball. Such impacts can lead to contusions, fractures, eye injuries, concussions or even, in rare cases, death. Coaches, players, parents and physicians are rightly concerned about the risk of head injury in soccer. Current research shows that selected soccer players have some degree of cognitive dysfunction. It is important to determine the reasons behind such deficits. Purposeful heading has been blamed, but a closer look at the studies that focus on heading has revealed methodological concerns that question the validity of blaming purposeful heading of the ball. The player's history and age (did they play when the ball was leather and could absorb significant amounts of water), alcohol intake, drug intake, learning disabilities, concussion definition and control group use/composition are all factors that cloud the ability to blame purposeful heading. What does seem clear is that a player's history of concussive episodes is a more likely explanation for cognitive deficits. While it is likely that the subconcussive impact of purposeful heading is a doubtful factor in the noted deficits, it is unknown whether multiple subconcussive impacts might have some lingering effects. In addition, it is unknown whether the noted deficits have any affect on daily life. Proper instruction in the technique is critical because if the ball contacts an unprepared head (as in accidental head-ball contacts), the potential for serious injury is possible. To further our understanding of the relationship of heading, head injury and cognitive deficits, we need to: learn more about the actual impact of a ball on the

Gastric rupture after blunt abdominal trauma is a rare injury with few reports in the literature. The purpose of this study was to review our experience with blunt gastric injuries and compare outcomes with small bowel or colon injuries. All patients with hollow viscus perforations after blunt abdominal trauma from 1992 to 2005 at our level I trauma center were reviewed. Of 35,033 blunt trauma admissions, there were 268 (0.7%) patients with a total of 319 perforating hollow viscus injuries, 25 (0.07%) of which were blunt gastric injuries. When compared with the small bowel or colon injuries, the blunt gastric injury group had a higher Injury Severity Score (22 versus 17, P = 0.04), more patients with a chest Abbreviated Injury Score greater than 2 (36% versus 12%, P < 0.01), and a shorter interval from injury to laparotomy (221 versus 366 minutes, P = 0.017). Multivariate analysis identified five independent risk factors for mortality: age older than 55 years, head Abbreviated Injury Score greater than 2, chest Abbreviated Injury Score greater than 2, the presence of hypotension on admission, and Glasgow Coma Scale 8 or less. The results of this study suggest that mortality in patients with blunt hollow viscus injuries can be attributed to concurrent head and chest injuries, but not the specific hollow viscus organ that is injured.

LAPAROSCOPIC MANAGEMENT OF RETROPERITONEAL INJURIES IN PENETRATING ABDOMINAL INJURIES.

Mosai, F

2017-09-01

Laparoscopy in penetrating abdominal injuries is now accepted and practiced in many modern trauma centres. However its role in evaluating and managing retroperitoneal injuries is not yet well established. The aim of this study was to document our experience in using laparoscopy in a setting of penetrating abdominal injuries with suspected retroperitoneal injury in haemodynamically stable patients. A retrospective descriptive study of prospectively collected data from a trauma unit at Dr George Mukhari Academic Hospital (DGMAH) was done. All haemodynamically stable patients with penetrating abdominal injury who were offered laparoscopy from January 2012 to December 2015 were reviewed and those who met the inclusion criteria were analysed. A total of 284 patients with penetrating abdominal injuries were reviewed and 56 met the inclusion criteria and were analysed. The median age was 30.8 years (15-60 years) and males constituted 87.5% of the study population. The most common mechanism of injury was penetrating stab wounds (62.5%). Forty-five patients (80.3%) were managed laparoscopically, of these n=16 (28.5%) had retroperitoneal injuries that required surgical intervention. The most commonly injured organ was the colon (19.6%). The conversion rate was 19.6% with most common indication for conversion been active bleeding (14%). The complication rate was 7.14% (N=4) and were all Clavien-Dindo grade 3. There were no recorded missed injuries and no mortality. The positive outcomes documented in this study with no missed injuries and absence of mortality suggests that laparoscopy is a feasible option in managing stable patients with suspected retroperitoneal injuries.

Ballet is a high-performance activity that requires an advanced level of technical skills. Ballet places great stress on tendons, muscles, bones, and joints and may act directly as a trigger of injury by overuse. 1) to describe the main types of injuries and affected areas related to classical ballet and 2) to compare the frequency of musculoskeletal injuries among professional and non-professional ballet dancers, considering possible gender differences among the professional dancers. A total of 110 questionnaires were answered by professional and non-professional dancers. The questionnaire contained items related to the presence of injury, the regions involved, and the mechanism of the injury. We observed a high frequency of musculoskeletal injuries, with ankle sprains accounting for 69.8% of injuries in professional dancers and 42.1% in non-professional dancers. Pirouettes were the most frequent mechanism of injury in professional dancers, accounting for 67.9% of injuries, whereas in the non-professional dancers, repetitive movement was the most common mechanism (28.1%). Ankle sprains occurred in 90% of the women's injuries, and muscle sprains occurred in 54.5% of the men's injuries. The most frequent injury location was the ankle joint in both sexes among the professional dancers, with 67.6% in women and 40.9% in men. The identification of the mechanism of injury and time of practice may contribute to better therapeutic action aimed at the proper function of the dancers' bodies and improved performance by these athletes.

Full Text Available Abstract Background Processes of restenosis, following arterial injury, are complex involving different cell types producing various cytokines and enzymes. Among those enzymes, smooth muscle cell-derived matrix metalloproteinases (MMPs are thought to take part in cell migration, degrading of extracellular matrix, and neointima formation. MMP-9, also known as gelatinase B, is expressed immediately after vascular injury and its expression and activity can be inhibited by statins. Using an established in vivo model of vascular injury, we investigated the effect of the HMG-CoA reductase inhibitor rosuvastatin on MMP-9 expression and neointima formation. Materials and methods 14-week old male Sprague Dawley rats underwent balloon injury of the common carotid artery. Half of the animals received rosuvastatin (20 mg/kg body weight/day via oral gavage, beginning 3 days prior to injury. Gelatinase activity and neointima formation were analyzed 3 days and 14 days after balloon injury, respectively. 14 days after vascular injury, proliferative activity was assessed by staining for Ki67. Results After 14 days, animals in the rosuvastatin group showed a decrease in total neointima formation (0.194 ± 0.01 mm2 versus 0.124 ± 0.02 mm2, p Conclusions Rosuvastatin attenuates neointima formation without affecting early MMP-9 activity in a rat model of vascular injury.

In previous studies, collagen based matrices have been implanted into the site of lesion in different models of brain injury. We hypothesized that semisynthetic collagen matrix can have neuroprotective function in the setting of traumatic brain injury. Rats were subjected to sham injury or controlled cortical impact. They either received extracellular matrix graft (DuraGen) over the injury site or did not receive any graft and underwent beam balance/beam walking test at post injury days 1-5 and Morris water maze at post injury days 14-18. Animals were sacrificed at day 18 for tissue analysis. Collagen matrix implantation in injured rats did not affect motor function (beam balance test: p = 0.627, beam walking test: p = 0.921). However, injured group with collagen matrix had significantly better spatial memory acquisition (p < 0.05). There was a significant reduction in lesion volume, as well as neuronal loss in CA1 (p < 0.001) and CA3 (p < 0.05) regions of the hippocampus in injured group with collagen matrix (p < 0.05). Collagen matrix reduces contusional lesion volume, neuronal loss, and cognitive deficit after traumatic brain injury. Further studies are needed to demonstrate the mechanisms of neuroprotection by collagen matrix.

Rib fractures are considered a marker of exposure to significant traumatic energy. In children, because of high elasticity of the chest wall, higher energy levels are necessary for ribs to fracture. The purpose of this study was to analyze patterns of associated injuries in children as compared with adults, all of whom presented with rib fractures. A retrospective cohort study involving blunt trauma patients with rib fractures registered in the National Trauma Registry was conducted. Of 6,995 trauma victims who were found to suffer from rib fractures, 328 were children and 6,627 were adults. Isolated rib fractures without associated injuries occurred in 19 children (5.8%) and 731 adults (11%). More adults had 4 or more fractured ribs compared with children (P pneumothorax (P = .006), spleen, and liver injury (P < .001). Mortality rate was 5% in both groups. The incidence of associated head, thoracic, and abdominal solid organ injuries in children was significantly higher than in adults suffering from rib fractures. In spite of a higher Injury Severity Score and incidence of associated injuries, mortality rate was similar. Mortality of rib fracture patients was mostly affected by the presence of extrathoracic injuries. Copyright © 2014 Elsevier Inc. All rights reserved.

We wished to evaluate the incidence of non-contiguous spinal injury in the cervicothoracic junction (CTJ) or the upper thoracic spines on cervical spinal MR images in the patients with cervical spinal injuries. Seventy-five cervical spine MR imagings for acute cervical spinal injury were retrospectively reviewed (58 men and 17 women, mean age: 35.3, range: 18-81 years). They were divided into three groups based on the mechanism of injury; axial compression, hyperflexion or hyperextension injury, according to the findings on the MR and CT images. On cervical spine MR images, we evaluated the presence of non-contiguous spinal injury in the CTJ or upper thoracic spine with regard to the presence of marrow contusion or fracture, ligament injury, traumatic disc herniation and spinal cord injury. Twenty-one cases (28%) showed CTJ or upper thoracic spinal injuries (C7-T5) on cervical spinal MR images that were separated from the cervical spinal injuries. Seven of 21 cases revealed overt fractures in the CTJs or upper thoracic spines. Ligament injury in these regions was found in three cases. Traumatic disc herniation and spinal cord injury in these regions were shown in one and two cases, respectively. The incidence of the non-contiguous spinal injuries in CTJ or upper thoracic spines was higher in the axial compression injury group (35.5%) than in the hyperflexion injury group (26.9%) or the hyperextension (25%) injury group. However, there was no statistical significance (ρ > 0.05). Cervical spinal MR revealed non-contiguous CTJ or upper thoracic spinal injuries in 28% of the patients with cervical spinal injury. The mechanism of cervical spinal injury did not significantly affect the incidence of the non-contiguous CTJ or upper thoracic spinal injury

Self-esteem and coping strategies have been important factors in athletes' response to injury and subsequent rehabilitation. Specifically, athletic injury has been negatively associated with self-esteem, while certain coping strategies may enhance adherence to rehabilitation (1, 4). Little is known, however, concerning the effect of acute (sudden specific event) versus chronic injury (repetitive injury over a prolonged period of time) on self-esteem and coping strategies. The Rosenberg Self-esteem Inventory (3), selected subscales of the Ways of Coping Questionnaire (2), and a demographic questionnaire were administered. The subscales of Ways of Coping Questionnaire employed were Seeking Social Support, Accepting Responsibility for the injury, and Escape Avoidance of the injury. To assess the influence of acute versus chronic injury status, effect sizes (ES) were calculated. Although no difference was found for Accepting Responsibility, chronically injured athletes scored higher on Escape/Avoidance (M = 2.4 vs 1.9, SD = 1.2 vs .6, ES = .52) and lower on Seeking Social Support (M = 2.5 vs 2.8, SD = .6 vs .4, ES = .47) than athletes with acute injuries. Those with chronic injuries also second more negatively on self-esteem (M = 6.2 vs 4.4, SD = 1.2 vs 1.2, ES = 1.30) than acutely injured athletes. These preliminary results suggest the type of injury may differentially affect self-esteem and coping behavior. As self-esteem is theorized to be relatively stable construct, it is perhaps not surprising that chronic injuries have a greater effect than acute injuries. Chronically injured athletes also sought social support less and engaged in more escape/avoidance behavior, suggesting that they cope with injury differently than those with acute injuries.

Full Text Available Objective To study the characteristics and mechanism of mine blast injury that wading in shoal of different depths through an animal model. Methods Ninety-six healthy adult New Zealand white rabbits weighing 2.19±0.12kg were randomly divided into land group (n=16, limb wading group (n=16, the water depth reaching up the middle of the thighs of rabbits, and chest wading group (n=16, the water depth reaching up the thoracic xiphoid, stress test group (n=30, fake injury group (n=18. Punctiform burster was used to simulate landmine. Electric ignited the simulated mine away, causing landmine explosion injury to rabbits' one-sided hind limbs in upright state. High-speed photography was used to observe the movement of water accompanying the simulated mine explosion. Arterial blood serum markers of myocardial injury (CK-MB, cTnI and nerve injury (MBP, NSE were detected before injury, and 3, 6 and 12h after injury, and echocardiography, electrocardiography, CT, DSA and other examinations were implemented at the same time. Survival animals were killed 12h after injury for anatomy to record their injuries to the limbs and distant organs. The histopathological examination was done to define the injury characteristics further. Results Feet and distal tibia were broken, and closed femoral fractures and arterial damage were often found away from the stump in limb wading group. This type of injury was different from the mop-like tearing tissue in the land group. Chest, abdominal organs and the brain, spinal cord injury in wading group were more severe than those in land group. There were higher incidences of chest, abdominal organs and spinal cord injury in chest wading Group. Conclusion The energy transfer of underwater explosion is affected by water depth and limbs or trunk mutually, which is an important mechanism of the complex and serious injuries in the wading group. The wading depth is an important factor affecting severity of the injury. Based on

Injuries are a serious medical and social problem, especially when accompanied by distant or deferred effects, often causing serious dysfunctions and permanent disability for life. The study aimed at presenting the incidence of injuries of urban and rural population treated in a district hospital in eastern Poland. The study was carried out in the Independent Public Health Care Institution in Kraśnik in 2011 among patients hospitalized in the Department of Trauma Surgery and Orthopedic Unit who sustained injuries. Medical records of 795 patients - 326 women and 469 men, aged 10-99 years, were analyzed. During the period considered among those hospitalized due to injuries, men (59%), those aged 50-59 years (19.0%), and living in rural areas (72.7%) predominated. Injuries most commonly affected the head (18.87%), elbow and forearm (16.86%), knee and lower leg (16.60%), and the hip and thigh (13.96%). Average hospital stay was 5.65 days and was the longest for hip and thigh injuries (11.86 days). Injuries occurred most frequently in the population of patients living in rural areas, often among men, usually on weekdays and in the morning.

Paving the road to negligence: the compensation for research-related injuries in Spain.

Ramiro Avilés, Miguel A

2015-01-01

The planned reform of the regulation of clinical trials in Spain has reopened the debate over how to regulate research-related injuries. Act 29/2006 and Royal Decree 223/2004 regulate the insurance of research-related injuries, and they include a general clause requiring mandatory insurance and imposing a no-fault compensation system; they also contain an exception clause enabling clinical trials to be carried out without insurance under some conditions, and an exclusion clause excluding compensation when there is no causal connection between injuries and a clinical trial. National legislation is under review, affecting the requirement of mandatory insurance and paving the road to a liability system based on negligence, which will affect the level of protection of the persons enrolled in clinical trials because it would not ensure compensation. Regulatory texts on individuals' participation as research subjects should include not only mandatory insurance, but also a no-fault compensation system for cases when voluntary research subjects are injured, irrespective of negligence.

To describe the leading mechanisms of hospitalised unintentional injury in Australian Aboriginal children and identify the injury mechanisms with the largest inequalities between Aboriginal and non-Aboriginal children. We used linked hospital and mortality data to construct a whole of population birth cohort including 1,124,717 children (1,088,645 non-Aboriginal and 35,749 Aboriginal) born in the state of New South Wales (NSW), Australia, between 1 July 2000 and 31 December 2012. Injury hospitalisation rates were calculated per person years at risk for injury mechanisms coded according to the ICD10-AM classification. The leading injury mechanisms in both groups of children were falls from playground equipment. For 66 of the 69 injury mechanisms studied, Aboriginal children had a higher rate of hospitalisation compared with non-Aboriginal children. The largest relative inequalities were observed for injuries due to exposure to fire and flame, and the largest absolute inequalities for injuries due to falls from playground equipment. Aboriginal children in NSW experience a significant higher burden of unintentional injury compared with their non-Aboriginal counterparts. Implications for Public Health: We suggest the implementation of targeted injury prevention measures aimed at injury mechanism and age groups identified in this study. © 2016 The Authors.

The Impact of Liver Graft Injury on Cancer Recurrence Posttransplantation.

2017-11-01

Liver transplantation is the most effective treatment for selected patients with hepatocellular carcinoma. However, cancer recurrence, posttransplantation, remains to be the critical issue that affects the long-term outcome of hepatocellular carcinoma recipients. In addition to tumor biology itself, increasing evidence demonstrates that acute-phase liver graft injury is a result of hepatic ischemia reperfusion injury (which is an inevitable consequence during liver transplantation) and may promote cancer recurrence at late phase posttransplantation. The liver grafts from living donors, donors after cardiac death, and steatotic donors have been considered as promising sources of organs for liver transplantation and are associated with high incidence of liver graft injury. The acute-phase liver graft injury will trigger a series of inflammatory cascades, which may not only activate the cell signaling pathways regulating the tumor cell invasion and migration but also mobilize the circulating progenitor and immune cells to facilitate tumor recurrence and metastasis. The injured liver graft may also provide the favorable microenvironment for tumor cell growth, migration, and invasion through the disturbance of microcirculatory barrier function, induction of hypoxia and angiogenesis. This review aims to summarize the latest findings about the role and mechanisms of liver graft injury resulted from hepatic ischemia reperfusion injury on tumor recurrence posttransplantation, both in clinical and animal cohorts.

Full Text Available BACKGROUND This study aims to record the prevalence and pattern of various ophthalmic manifestations in patients of head injury and to attempt a correlation between the ocular signs, neurological signs and final outcome. MATERIALS AND METHODS Hundred and twenty patients with head injury having ocular findings, presenting from December 2014 to July 2016, were taken for study. Detailed ophthalmological examination of the patients was carried out and the results of the study are depicted in the form of percentages, graphs and charts. RESULTS The most common cause of head injury found in our study was road traffic accident. The commonest eye finding was oedema and ecchymosis of eyelids. Prime causal factors affecting visual acuity found in our study were corneal tear, globe rupture, optic nerve injury and avulsion of eyeball. CONCLUSION Head injuries with ocular manifestations occur in younger age group. Road traffic accident was the most common cause. Males have to work outside their home for their jobs more than that of females. So they are more prone to accidents. Oedema and ecchymosis of eyelids constitute the most common ocular finding. Patients with mild ocular injuries pointed towards good visual prognosis. Most of them had mild head injury and hence good prognosis in terms of survival of the patient. The patients with severe ocular injuries like corneal tear, globe rupture and optic nerve injury showed poor visual prognosis.

Regulatory miRNAs play a role in vascular biology and are involved in biochemical and molecular pathways dysregulated during vascular injury. Collection and integration of functional miRNA data into these pathways can provide insight into pathogenesis at the site of injury; the same technologies applied to biofluids may provide diagnostic or surrogate biomarkers. miRNA was analyzed from mesentery and serum from rats given vasculotoxic compounds for 4 days. Fenoldopam, dopamine and midodrine each alter hemodynamics and are associated with histologic evidence of vascular injury, while yohimbine is vasoactive but does not cause histologic evidence of vascular injury in rat. There were 38 and 35 miRNAs altered in a statistically significant manner with a fold change of 2 or greater in mesenteries of fenoldopam- and dopamine-dosed rats, respectively, with 9 of these miRNAs shared. 10 miRNAs were altered in rats given midodrine; 6 were shared with either fenoldopam or dopamine. In situ hybridization demonstrated strong expression and co-localization of miR-134 in affected but not in adjacent unaffected vessels. Mesenteric miRNA expression may provide clarity or avenues of research into mechanisms involved in vascular injury once the functional role of specific miRNAs becomes better characterized. 102 miRNAs were altered in serum from rats with drug-induced vascular injury. 10 miRNAs were commonly altered in serum from dopamine and either fenoldopam or midodrine dosed rats; 18 of these 102 were also altered in mesenteries from rats with drug-induced vascular injury, suggesting their possible utility as peripheral biomarkers. -- Highlights: ► Mesentery and serum were examined from rats given vasoactive compounds for 4 days. ► 72 miRNAs were altered in mesenteries from rats with vascular injury. ► miR-134 was localized to affected but not adjacent unaffected vessels. ► 102 miRNAs were changed in serum from rats with vascular injury. ► 18 miRNAs changed in both

Psychosocial consequences of head injury in children and adolescents: implications for rehabilitation.

Studies measuring psychosocial outcome in children and adolescents have shown that head injury leads to cognitive impairment which is directly related to the severity of injury in those with very severe head injury. Psychiatric disorders are also related to the severity of injury but here the relationship suggests that mediating factors are involved. No specific pattern of post-traumatic psychological/psychiatric dysfunction emerges from the studies, but it is clear that, as with adults, psychosocial recovery lags behind physical. Head injury affects the functioning of the young person in the family, at school, and within the wider community, often resulting in a secondary handicap of low self-esteem. The multitude of deficits which are a consequence of severe head injury present a challenge for rehabilitation specialists. A multi-disciplinary, multi-specialist, and multi-agency response is required. As a result, families are often presented with a bewildering array of treatments and programmes at different agencies. A case manager can be helpful in ensuring the appropriate use of available resources and can be the one professional in charge of a coordinating case record.

Improving acute kidney injury diagnostics using predictive analytics.

Basu, Rajit K; Gist, Katja; Wheeler, Derek S

2015-12-01

Acute kidney injury (AKI) is a multifactorial syndrome affecting an alarming proportion of hospitalized patients. Although early recognition may expedite management, the ability to identify patients at-risk and those suffering real-time injury is inconsistent. The review will summarize the recent reports describing advancements in the area of AKI epidemiology, specifically focusing on risk scoring and predictive analytics. In the critical care population, the primary underlying factors limiting prediction models include an inability to properly account for patient heterogeneity and underperforming metrics used to assess kidney function. Severity of illness scores demonstrate limited AKI predictive performance. Recent evidence suggests traditional methods for detecting AKI may be leveraged and ultimately replaced by newer, more sophisticated analytical tools capable of prediction and identification: risk stratification, novel AKI biomarkers, and clinical information systems. Additionally, the utility of novel biomarkers may be optimized through targeting using patient context, and may provide more granular information about the injury phenotype. Finally, manipulation of the electronic health record allows for real-time recognition of injury. Integrating a high-functioning clinical information system with risk stratification methodology and novel biomarker yields a predictive analytic model for AKI diagnostics.

Anti-inflammatory management for tendon injuries - friends or foes?

Directory of Open Access Journals (Sweden)

Chan Kai-Ming

2009-10-01

Full Text Available Abstract Acute and chronic tendon injuries are very common among athletes and in sedentary population. Most physicians prescribe anti-inflammatory managements to relieve the worst symptoms of swelling and pain, including non-steroidal anti-inflammatory drugs, corticosteroids and physical therapies. However, experimental research shows that pro-inflammatory mediators such as prostaglandins may play important regulatory roles in tendon healing. Noticeably nearly all cases of chronic tendon injuries we treat as specialists have received non-steroidal anti-inflammatory drugs by their physician, suggesting that there might be a potential interaction in some of these cases turning a mild inflammatory tendon injury into chronic tendinopathy in predisposed individuals. We are aware of the fact that non-steroidal anti-inflammatory drugs and corticosteroids may well have a positive effect on the pain control in the clinical situation whilst negatively affect the structural healing. It follows that a comprehensive evaluation of anti-inflammatory management for tendon injuries is needed and any such data would have profound clinical and health economic importance.

Weight-training sports, including weightlifting, powerlifting, bodybuilding, strongman, Highland Games, and CrossFit, are weight-training sports that have separate divisions for males and females of a variety of ages, competitive standards, and bodyweight classes. These sports may be considered dangerous because of the heavy loads commonly used in training and competition. Our objective was to systematically review the injury epidemiology of these weight-training sports, and, where possible, gain some insight into whether this may be affected by age, sex, competitive standard, and bodyweight class. We performed an electronic search using PubMed, SPORTDiscus, CINAHL, and Embase for injury epidemiology studies involving competitive athletes in these weight-training sports. Eligible studies included peer-reviewed journal articles only, with no limit placed on date or language of publication. We assessed the risk of bias in all studies using an adaption of the musculoskeletal injury review method. Only five of the 20 eligible studies had a risk of bias score ≥75 %, meaning the risk of bias in these five studies was considered low. While 14 of the studies had sample sizes >100 participants, only four studies utilized a prospective design. Bodybuilding had the lowest injury rates (0.12-0.7 injuries per lifter per year; 0.24-1 injury per 1000 h), with strongman (4.5-6.1 injuries per 1000 h) and Highland Games (7.5 injuries per 1000 h) reporting the highest rates. The shoulder, lower back, knee, elbow, and wrist/hand were generally the most commonly injured anatomical locations; strains, tendinitis, and sprains were the most common injury type. Very few significant differences in any of the injury outcomes were observed as a function of age, sex, competitive standard, or bodyweight class. While the majority of the research we reviewed utilized retrospective designs, the weight-training sports appear to have relatively low rates of injury compared with common team

Competitive sports yield high demands on the musculoskeletal system, accordingly muscle injuries are a common complication. Early imaging clarification of the muscles in cases of a trauma is essential in order to define the exact location of the lesion, the affected muscles, the extent and the degree of the injury as well as to define possible concomitant complications. In the case of a professional athlete, the assessment made by MRI is important for defining the individually required resting period for a riskless resumption of the sporting activities. (orig.) [de

Full Text Available Traumatic injuries to the brachial plexus in adults are severely debilitating. They generally affect young individuals. A thorough understanding of the anatomy, clinical evaluation, imaging and electrodiagnostic assessments, treatment options and proper timing of surgical interventions will enable nerve surgeons to offer optimal care to patients. Advances in microsurgical technique have improved the outcome for many of these patients. The treatment options offer patients with brachial plexus injuries the possibility of achieving elbow flexion, shoulder stability with limited abduction and the hope of limited but potentially useful hand function.

To analyse the frequency and characteristics of sports injuries and illnesses incurred during the World Athletics Championships. Prospective recording of newly occurred injuries and illnesses. Twelfth International Association of Athletics Federations World Championships in Athletics 2009 in Berlin, Germany. National team physicians and physiotherapists and 1979 accredited athletes; Local Organising Committee physicians working in the Medical Centres. Incidence and characteristics of newly incurred injuries and illnesses. 236 injury incidents with 262 injured body parts and 269 different injury types were reported, representing an incidence of 135.4 injuries per 1000 registered athletes. Eighty percent affected the lower extremity. Thigh strain (13.8%) was the main diagnosis. Overuse (44.1%) was the predominant cause. Most injuries were incurred during competition (85.9%). About 43.8% of all injury events were expected to result in time-loss. 135 illnesses were reported, signifying an incidence of 68.2 per 1000 registered athletes. Upper respiratory tract infection was the most common condition (30.4%) and infection was the most frequent cause (32.6%). The incidence of injury and illnesses varied substantially among the events. The risk of injury varied with each discipline. Preventive measures should be specific and focused on minimising the potential for overuse. Attention should be paid to ensure adequate rehabilitation of previous injuries. The addition of the illness part to the injury surveillance system proved to be feasible. As most illnesses were caused by infection of the respiratory tract or were environmentally related, preventive interventions should focus on decreasing the risk of transmission, appropriate event scheduling and heat acclimatisation.

The authors examined the clinical characteristics of homeless patients presenting to emergency departments (EDs) in the United States, with a focus on unintentional and intentional injury events and related comorbid conditions. The study included a nationally representative sample of patients presenting to EDs with data obtained from the 2007 through 2010 National Hospital Ambulatory Medical Care Survey (NHAMCS). Descriptive and analytical epidemiologic analyses were employed to examine injuries among homeless patients. Homeless persons made 603,000 visits annually to EDs, 55% of which were for injuries, with the majority related to unintentional (52%) and self-inflicted (23%) injuries. Multivariate logistic regression analyses revealed that homeless patients had a higher odds of presenting with injuries related to unintentional (odds ratio [OR]=1.4. 95% confidence interval [CI]=1.1 to 1.9), self-inflicted (OR=6.0, 95% CI=3.7 to 9.5), and assault (OR=3.0, 95% CI=1.5 to 5.9) injuries. A better understanding of the injuries affecting homeless populations may provide medical and public health professionals insight into more effective ways to intervene and limit further morbidity and mortality related to specific injury outcomes. © 2014 by the Society for Academic Emergency Medicine.

A secondary data analysis of a prospective cohort study was conducted to explore how different definitions of injury affect the results of risk factor analyses. Modern circus artists (n=1281) were followed for 828,547 performances over a period of 49 months (2004-2008). A univariate risk factor analysis (age, sex, nationality, artist role) estimating incidence rate ratios (IRR) with 95% confidence intervals (95% CI) was conducted using three injury definitions: (1) medical attention injuries, (2) time-loss injuries resulting in ≥1 missed performances (TL-1) and (3) time-loss injuries resulting in >15 missed performances (TL-15). Results of the risk factor analysis were dependent on the injury definition. Sex (females to male; IRR=1.13, 95% CI; 1.02-1.25) and age over 30 (30 years; IRR=1.37, 95% CI; 1.07-1.79) were risk factors for medical attention injuries only. Risk of injury for Europeans compared with North Americans was higher for TL-1 and TL-15 injuries compared with medical attention injuries. Finally, non-sudden load artists (low-impact acts) were less likely than sudden load artists (high-impact acts) to have TL-1 injuries, but the risk of medical attention injuries was similar. The choice of injury definition can have effects on the magnitude and direction of risk factor analyses. © 2010 John Wiley & Sons A/S.

To investigate tree-related injuries in Solomon Islands by the types of trees involved, who is affected and the types of injuries caused. Descriptive case series of all cases of injuries related to trees presenting to the National Referral Hospital in Honiara from 1994 to 2011. Data were collected by the attending clinician using a Trauma Epidemiology form, which provides information on age, sex, cause of injury and type of fracture. Number of injuries by tree type, sex and age. Of the 7651 injuries in the database, 1107 (14%) were caused by falls from trees. Falls from coconut trees led to the highest number of injuries, followed by falls from mango, guava, apple and nut trees. Overall, 85% of injuries occurred in individuals aged trees, 77% of patients were aged tree types. Overall, 71% of injuries occurred among males. Of all injuries, 92% were fractures, 3% were dislocations and 5% were non-fracture, non-dislocation injuries. The arm (including wrist, elbow and hand) was the most common location of injury across all tree types. Distal radius fractures in the forearm were particularly common, as were ulna fractures. While mangos and guavas are undeniably delicious, the quest for their flesh can be hazardous. Children will always climb trees, but the search for food among children in lower-income settings may lead to higher rates of injury.

Environmental Subconcussive Injury, Axonal Injury, and Chronic Traumatic Encephalopathy

Full Text Available Brain injury occurs in two phases: the initial injury itself and a secondary cascade of precise immune-based neurochemical events. The secondary phase is typically functional in nature and characterized by delayed axonal injury with more axonal disconnections occurring than in the initial phase. Axonal injury occurs across the spectrum of disease severity, with subconcussive injury, especially when repetitive, now considered capable of producing significant neurological damage consistent with axonal injury seen in clinically evident concussion, despite no observable symptoms. This review is the first to introduce the concept of environmental subconcussive injury (ESCI and sets out how secondary brain damage from ESCI once past the juncture of microglial activation appears to follow the same neuron-damaging pathway as secondary brain damage from conventional brain injury. The immune response associated with ESCI is strikingly similar to that mounted after conventional concussion. Specifically, microglial activation is followed closely by glutamate and calcium flux, excitotoxicity, reactive oxygen species and reactive nitrogen species (RNS generation, lipid peroxidation, and mitochondrial dysfunction and energy crisis. ESCI damage also occurs in two phases, with the primary damage coming from microbiome injury (due to microbiome-altering events and secondary damage (axonal injury from progressive secondary neurochemical events. The concept of ESCI and the underlying mechanisms have profound implications for the understanding of chronic traumatic encephalopathy (CTE etiology because it has previously been suggested that repetitive axonal injury may be the primary CTE pathogenesis in susceptible individuals and it is best correlated with lifetime brain trauma load. Taken together, it appears that susceptibility to brain injury and downstream neurodegenerative diseases, such as CTE, can be conceptualized as a continuum of brain resilience. At one end

Information about the burden of (non-fatal) road traffic injury is very useful to further improve road safety policy. Previous studies calculated the burden of injury in individual countries. This paper estimates and compares the burden of non-fatal serious road traffic injuries in six EU countries/regions: Austria, Belgium, England, The Netherlands, the Rhône region in France and Spain. It is a cross-sectional study based on hospital discharge databases. of study are patients hospitalized with MAIS3+ due to road traffic injuries. The burden of injury (expressed in years lived with disability (YLD)) is calculated applying a method that is developed within the INTEGRIS study. The method assigns estimated disability information to the casualties using the EUROCOST injury classification. The average burden per MAIS3+ casualty varies between 2.4 YLD and 3.2 YLD per casualty. About 90% of the total burden of injury of MAIS3+ casualties is due to lifelong consequences that are experienced by 19% to 33% of the MAIS3+ casualties. Head injuries, spinal cord injuries and injuries to the lower extremities are responsible for more than 90% of the total burden of MAIS3+ road traffic injuries. Results per transport mode differ between the countries. Differences between countries are mainly due to differences in age distribution and in the distribution over EUROCOST injury groups of the casualties. The analyses presented in this paper can support further improvement of road safety policy. Countermeasures could for example be focused at reducing skull and brain injuries, spinal cord injuries and injuries to the lower extremities, as these injuries are responsible for more than 90% of the total burden of injury of MAIS3+ casualties.

Full Text Available Objective To investigate the current global status of military ocular injury for the purpose of improving the level of domestic epidemiological investigation,in order to improve treatment strategies,and to prevent and reduce the incidence of military ocular injury in Chinese PLA.Methods The epidemiological literature concerning military ocular injury occurring in our country and abroad in recent five years was retrieved by information research;the problems and experiences in the aspects of epidemiological survey,registry,data collection,systematic treatment and prevention of military ocular injury existed in PLA were also summarized and analyzed.Results There were currently no systematic epidemiological data about ocular injury in PLA.A few articles about epidemiological study on ocular injury showed that servicemen were the high risk population of ocular injury.Both in peacetime or wartime the ocular injury was the primary cause leading to monocular blindness of soldiers.As to the ocular injury,in 51.55% of the patients,it occurred in the military operations and work,and 30.31% in military training.The incidence of ocular injury was different in various services,for example,the incidence in the internal security forces of armed police could be as high as 78.85% due to training of martial arts and boxing and wrestling.The deficiency of microsurgery equipments and untimely evacuation were the main causes affecting prognosis during treatment course in primary military hospitals.Conclusions Military affairs,physical training,military maneuver and defense constructions are the main causes of ocular injury in servicemen,and young male soldiers are the main group for prevention and treatment for military ocular injury.More attention should be paid to the epidemiological survey of military ocular injury to find out the causes leading to ocular injury,to improve treatment strategies,to formulate feasible protective measures and then military ocular

Intraear Compensation of Field Corn, Zea mays, from Simulated and Naturally Occurring Injury by Ear-Feeding Larvae.

Steckel, S; Stewart, S D

2015-06-01

Ear-feeding larvae, such as corn earworm, Helicoverpa zea Boddie (Lepidoptera: Noctuidae), can be important insect pests of field corn, Zea mays L., by feeding on kernels. Recently introduced, stacked Bacillus thuringiensis (Bt) traits provide improved protection from ear-feeding larvae. Thus, our objective was to evaluate how injury to kernels in the ear tip might affect yield when this injury was inflicted at the blister and milk stages. In 2010, simulated corn earworm injury reduced total kernel weight (i.e., yield) at both the blister and milk stage. In 2011, injury to ear tips at the milk stage affected total kernel weight. No differences in total kernel weight were found in 2013, regardless of when or how much injury was inflicted. Our data suggested that kernels within the same ear could compensate for injury to ear tips by increasing in size, but this increase was not always statistically significant or sufficient to overcome high levels of kernel injury. For naturally occurring injury observed on multiple corn hybrids during 2011 and 2012, our analyses showed either no or a minimal relationship between number of kernels injured by ear-feeding larvae and the total number of kernels per ear, total kernel weight, or the size of individual kernels. The results indicate that intraear compensation for kernel injury to ear tips can occur under at least some conditions. © The Authors 2015.

Surfers are subjected to external factors (ocean currents, wind orientation, wave size, contact with the board and other surfers) that require quick and efficient adaptations, increasing the risk of injury while riding waves. This study aimed to determine the incidence of injuries over a 12-month period in Portuguese surfers and to analyse the associated factors. The sample included 1,016 Portuguese surfers, aged between 8 and 64 years; 853 (84%) were male. A questionnaire was administered during the stages of the Regional Circuit Surf of Portugal. Three hundred and one (29.6%) surfers had an injury in the previous year, with a total of 398 injuries. There were 1.23 injuries per 1,000 hours of surfing. The most common injuries were lacerations (23.5%), located in the knee and leg (16.7%). Impacts of the board (27.1%), and injuries during paddling (17.9%) were the most prevalent injury mechanisms. Competitor surfers presented a higher risk of sustaining surfing- related injuries than recreational surfers (odds ratio= 1.81; 95%CI: 1.26-2.62; p=0.002). Individuals who had surfed for less than five years were at 1.65 more risk (95%CI: 1.13- 2.39; p=0.009) than those who had surfed for more than 10 years; surfers who trained at least three times a week had 1.42 the risk (95%CI: 1.08-1.87; p=0.011) than those who trained less. Injuries were frequent among Portuguese surfers, with specific affected body areas, mainly caused by impact with the board. It ́s necessary to create injury prevention strategies, including specific trainings and the use of protection material.

The purpose of this study was to analyze data according to gender, age, cause, number of traumatized teeth, time elapsed before treatment and type of tooth from the records of traumatized children. A retrospective study was conducted in the Department of Paediatric Dentistry at the University Dental Clinic in Zagreb, Croatia using the documentation of 128 patients (61 males and 67 females) aged 1 month to 6 years with injuries of primary teeth between February 2009 and January 2013. Trauma was seen in 217 primary teeth, which implies that the number of injured primary teeth was 1.69 per child. The maxillary central incisors were the most frequently affected teeth (81.1%), they were followed by maxillary lateral incisors, while the least affected were mandibular central incisors. Traumatic dental injuries involved periodontal tissue 2.82 times more frequently than hard dental and pulp tissue. The main cause of teeth injury was fall (67.2%) and the majority of injuries occurred at home (51.6%) (p<0.05). Of 128 patients who received treatment 71 (55.5%) also had soft-tissue injuries. The distribution of soft-tissue injuries by gender (35 males, 36 females) was not statistically significant. Comparing children with soft-tissue injuries and those without them, a statistically significant difference was found in the time of arrival (p<0.01). The results of this study showed the need of informing about preventive measures against falls at home and the methods of providing first aid in dental trauma injuries.

Full Text Available Abstract Background Hamstring injury is one of the most common injuries affecting gaelic footballers, similar to other field sports. Research in other sports on whether residual hamstring weakness is present after hamstring injury is inconsistent, and no study has examined this factor in irish gaelic footballers. The aim of this study was to examine whether significant knee muscle weakness is present in male Irish gaelic footballers who have returned to full activity after hamstring injury. Methods The concentric isokinetic knee flexion and extension strength of 44 members of a university gaelic football team was assessed at 60, 180 and 300 degrees per second using a Contrex dynamometer. Results Fifteen players (34% reported a history of hamstring strain, with 68% of injuries affecting the dominant (kicking limb. The hamstrings were significantly stronger (p 0.05 using this comparison. The previously unilaterally injured hamstrings were significantly weaker (p Conclusion Hamstring muscle weakness was observed in male Irish gaelic footballers with a history of hamstring injury. This weakness is most evident when comparisons are made to multiple control populations, both within and between subjects. The increased strength of the dominant limb should be considered as a potential confounding variable in future trials. The study design does not allow interpretation of whether these changes in strength were present before or after injury.

Sporting activities can cause injuries and overuse injuries of the extremities (OIE) in children have been shown to be more common than injuries caused by trauma. The lower extremity is more frequently affected than the upper extremity in OIE, but it is not known whether injury site and diagnosis vary in different sporting activities. To identify any differences between sports in relation to diagnoses and anatomical areas most likely to be injured. A search was made in November 2014 and again in June 2016 in PubMed, SportDiscus, PsycInfo and Web of Sciences. Search terms were: « overuse injuries OR cumulative trauma disorders OR musculoskeletal injuries » AND « extremity OR limb » AND « physical activity OR sport OR risk factor OR predictors OR exercises » AND « child OR adolescent OR young adults ». Inclusion criteria were: 1) prospective, retrospective, or cross-sectional study design; 2) age ≤19 years; 3) the articles must clearly state if reported cases were classified as traumatic or overuse injuries; 4) reporting on OIE in relation to a particular sports type, and 5) sample size >50. A blinded systematic review was conducted. In all, nine of the 736 identified articles were included, studying soccer, handball, orienteering, running, dance, and gymnastics. The incidence of OIE was given only in a few articles but at least the site and diagnosis of OIE were identifiable. The lower limb is more often affected than the upper in all sports covered, and, in general, the lower leg and knee are the two most often affected areas. However, in handball, the elbow was the second most often reported area, and in gymnastics injuries of the foot appeared to be more frequent than in the other sports. No differences in diagnoses were observed between sports types. Our work contributes new information, namely that the site of OIE in children and adolescents appears to vary only somewhat between different types of sports.

Aneurysmal subarachnoid hemorrhage (aSAH) is a medical emergency that accounts for 5% of all stroke cases. Individuals affected are typically in the prime of their lives (mean age 50 years). Approximately 12% of patients die before receiving medical attention, 33% within 48 hours and 50% within 30 days of aSAH. Of the survivors 50% suffer from permanent disability with an estimated lifetime cost more than double that of an ischemic stroke. Traditionally, spasm that develops in large cerebral arteries 3-7 days after aneurysm rupture is considered the most important determinant of brain injury and outcome after aSAH. However, recent studies show that prevention of delayed vasospasm does not improve outcome in aSAH patients. This finding has finally brought in focus the influence of early brain injury on outcome of aSAH. A substantial amount of evidence indicates that brain injury begins at the aneurysm rupture, evolves with time and plays an important role in patients’ outcome. In this manuscript we review early brain injury after aSAH. Due to the early nature, most of the information on this injury comes from animals and few only from autopsy of patients who died within days after aSAH. Consequently, we began with a review of animal models of early brain injury, next we review the mechanisms of brain injury according to the sequence of their temporal appearance and finally we discuss the failure of clinical translation of therapies successful in animal models of aSAH.

To review the current evidence for the epidemiology of pediatric injuries in martial arts. The relevant literature was searched using SPORT DISCUS (keywords: martial arts injuries, judo injuries, karate injuries, and taekwondo injuries and ProQuest (keywords: martial arts, taekwondo, karate, and judo), as well as hand searches of the reference lists. In general, the absolute number of injuries in girls is lower than in boys. However, when expressed relative to exposure, the injury rates of girls are higher. Injuries by body region reflect the specific techniques and rules of the martial art. The upper extremities tend to get injured more often in judo, the head and face in karate and the lower extremities in taekwondo. Activities engaged in at the time of injury included performing a kick or being thrown in judo, while punching in karate, and performing a roundhouse kick in taekwondo. Injury type tends to be martial art specific with sprains reported in judo and taekwondo and epistaxis in karate. Injury risk factors in martial arts include age, body weight and exposure. Preventive measures should focus on education of coaches, referees, athletes, and tournament directors. Although descriptive research should continue, analytical studies are urgently needed.

4: Rehabilitation after traumatic brain injury.

Khan, Fary; Baguley, Ian J; Cameron, Ian D

2003-03-17

Traumatic brain injury (TBI) commonly affects younger people and causes life-long impairments in physical, cognitive, behavioural and social function. The cognitive, behavioural and personality deficits are usually more disabling than the residual physical deficits. Recovery from TBI can continue for at least 5 years after injury. Rehabilitation is effective using an interdisciplinary approach, and close liaison with the patient, family and carers. The focus is on issues such as retraining in activities of daily living, pain management, cognitive and behavioural therapies, and pharmacological management. The social burden of TBI is significant, and therefore family education and counselling, and support of patient and carers, is important. General practitioners play an important role in providing ongoing support in the community, monitoring for medical complications, behavioural and personality issues, social reintegration, carer coping skills and return-to-work issues.

A multivariate tobit analysis of highway accident-injury-severity rates.

2012-03-01

Relatively recent research has illustrated the potential that tobit regression has in studying factors that affect vehicle accident rates (accidents per distance traveled) on specific roadway segments. Tobit regression has been used because accident rates on specific roadway segments are continuous data that are left-censored at zero (they are censored because accidents may not be observed on all roadway segments during the period over which data are collected). This censoring may arise from a number of sources, one of which being the possibility that less severe crashes may be under-reported and thus may be less likely to appear in crash databases. Traditional tobit-regression analyses have dealt with the overall accident rate (all crashes regardless of injury severity), so the issue of censoring by the severity of crashes has not been addressed. However, a tobit-regression approach that considers accident rates by injury-severity level, such as the rate of no-injury, possible injury and injury accidents per distance traveled (as opposed to all accidents regardless of injury-severity), can potentially provide new insights, and address the possibility that censoring may vary by crash-injury severity. Using five-year data from highways in Washington State, this paper estimates a multivariate tobit model of accident-injury-severity rates that addresses the possibility of differential censoring across injury-severity levels, while also accounting for the possible contemporaneous error correlation resulting from commonly shared unobserved characteristics across roadway segments. The empirical results show that the multivariate tobit model outperforms its univariate counterpart, is practically equivalent to the multivariate negative binomial model, and has the potential to provide a fuller understanding of the factors determining accident-injury-severity rates on specific roadway segments.

Despite overuse injuries being previously described as the most frequent in ballet, there are no studies on professional dancers providing the specific clinical diagnoses or type of injury based on the discipline. Overuse injuries are the most frequent injuries in ballet, with differences in the type and frequency of injuries based on discipline. Cross-sectional study; Level of evidence, 3. This was a descriptive cross-sectional study performed between January 1, 2005, and October 10, 2010, on injuries occurring in professional dancers from leading Spanish dance companies who practiced disciplines such as classical, neoclassical, contemporary, and Spanish ballet. Data, including type of injury, were obtained from specialized medical services at the Trauma Service, Fremap, Madrid, Spain. A total of 486 injuries were evaluated, a significant number of which were overuse disorders (P ballet (82.60%). Injuries were more frequent among female dancers (75.90%) and classical ballet (83.60%). A statistically significant prevalence of patellofemoral pain syndrome was found in the classical discipline (P = .007). Injuries of the adductor muscles of the thigh (P = .001) and of the low back facet (P = .02) in the Spanish ballet discipline and lateral snapping hip (P = .02) in classical and Spanish ballet disciplines were significant. Overuse injuries were the most frequent injuries among the professional dancers included in this study. The prevalence of injuries was greater for the most technically demanding discipline (classical ballet) as well as for women. Patellofemoral pain syndrome was the most prevalent overuse injury, followed by Achilles tendinopathy, patellar tendinopathy, and mechanical low back pain. Specific clinical diagnoses and injury-based differences between the disciplines are a key factor in ballet.

Whiplash injuries.

Whiplash injuries are very common and usually are associated with rear-end collisions. However, a whiplash injury can be caused by any event that results in hyperextension and flexion of the cervical spine. These injuries are of serious concern to all consumers due to escalating cost of diagnosis, treatment, insurance, and litigation. Most acute whiplash injury cases respond well to conservative treatments, which result in resolution of symptoms usually within weeks to a few months after the injury occurred. Chronic whiplash injuries often are harder to diagnose and treat and often result in poor outcomes. Current research shows that various structures in the cervical spine receive nociceptive innervation and potentially may be the cause of chronic pain symptoms. One potential pain generator showing promise is the facet or zygapophyseal joints. Various researchers have proven that these joints are injured during whiplash injuries and that diagnosis and temporary pain relief can be obtained with facet joint injections. The initial evaluation of any patient should follow an organized and stepwise approach, and more serious causes of neck pain must first be ruled out through the history, physical examination, and diagnostic testing. Treatment regimens should be evidence-based, focusing on treatments that have proven to be effective in treating acute and chronic whiplash injuries.

In a one year period, from 1 January 1986 to 31 December 1986, 4303 patients with sports injuries were treated at Aarhus Amtssygehus and Aarhus Kommunehospital. The mean age was 21.6 years (range 7-72 years) and 2830 were men. Two hundred and seventeen badminton injuries occurred in 208 patients (136 men) with a mean age of 29.6 years (range 7-57 years), constituting 4.1 percent of all sport injuries in Aarhus. Joints and ligaments were injured in 58.5 percent of the patients, most frequently located in the lower limb and significantly more often among patients younger than 30 years of age. Muscle injury occurred in 19.8 percent of the patients. This type of injury was significantly more frequent among patients older than 30 years of age. Most injuries were minor. However, 6.8 percent of the patients were hospitalized and 30.9 percent received additional treatment by a physician. As the risk of injury varies with age, attempts to plan training individually and to institute prophylactic measures should be made. PMID:2078802

Full Text Available The changes of excitability in affected neural networks can be used as a marker to study the temporal course of traumatic brain injury (TBI. The cerebellum is an ideal platform to study brain injury mechanisms at the network level using the electrophysiological methods. Within its crystalline morphology, the cerebellar cortex contains highly organized topographical subunits that are defined by two main inputs, the climbing and mossy fibers. Here we demonstrate the use of cerebellar evoked potentials (EPs mediated through these afferent systems for monitoring the injury progression in a rat model of fluid percussion injury (FPI. A mechanical tap on the dorsal hand was used as a stimulus, and EPs were recorded from the paramedian lobule (PML of the posterior cerebellum via multi-electrode arrays (MEA. Post-injury evoked response amplitudes (EPAs were analyzed on a daily basis for one week and compared with pre-injury values. We found a trend of consistently decreasing EPAs in all nine animals, losing as much as 72±4% of baseline amplitudes measured before the injury. Notably, our results highlighted two particular time windows; the first 24 hours of injury in the acute period and day-3 to day-7 in the delayed period where the largest drops (~50% and 24% were observed in the EPAs. In addition, cross-correlations of spontaneous signals between electrode pairs declined (from 0.47±0.1 to 0.35±0.04, p<0.001 along with the EPAs throughout the week of injury. In support of the electrophysiological findings, immunohistochemical analysis at day-7 post-injury showed detectable Purkinje cell loss at low FPI pressures and more with the largest pressures used. Our results suggest that sensory evoked potentials recorded from the cerebellar surface can be a useful technique to monitor the course of cerebellar injury and identify the phases of injury progression even at mild levels.

The effects of brachytherapy on normal brain tissue are not easily delineated in the clinical setting because of the presence of concurrent radiation-induced changes in the coexistent brain tumor. Sequential morphologic studies performed after the implantation of radioactive sources into the brains of experimental animals have provided a better understanding of the character and magnitude of the structural changes produced by interstitial irradiation on normal brain tissue. Furthermore, the clinical experience accumulated thus far provides not only relevant information, but also some guidelines for future treatment policies. In this paper, the authors summarize the experimental findings and review the pathologic and clinical features of brain injury caused by interstitial brachytherapy. A number of studies in the older literature examined the effects of radioisotopes such as radium-226 (38--43), radon-22 (44--46), gold-198 (29,47--50), tantalum-182 (29,51,52) yttrium-9- (50,53,54), and cobalt-60 (29,50,55). This review is restricted to low- and high-activity encapsulated iodine-125 ( 125 I) and iridium-192 ( 192 Ir), the isotopes that are most commonly used in current clinical practice

Enhanced Dentate Neurogenesis after Brain Injury Undermines Long-Term Neurogenic Potential and Promotes Seizure Susceptibility

Full Text Available Hippocampal dentate gyrus is a focus of enhanced neurogenesis and excitability after traumatic brain injury. Increased neurogenesis has been proposed to aid repair of the injured network. Our data show that an early increase in neurogenesis after fluid percussion concussive brain injury is transient and is followed by a persistent decrease compared with age-matched controls. Post-injury changes in neurogenesis paralleled changes in neural precursor cell proliferation and resulted in a long-term decline in neurogenic capacity. Targeted pharmacology to restore post-injury neurogenesis to control levels reversed the long-term decline in neurogenic capacity. Limiting post-injury neurogenesis reduced early increases in dentate excitability and seizure susceptibility. Our results challenge the assumption that increased neurogenesis after brain injury is beneficial and show that early post-traumatic increases in neurogenesis adversely affect long-term outcomes by exhausting neurogenic potential and enhancing epileptogenesis. Treatments aimed at limiting excessive neurogenesis can potentially restore neuroproliferative capacity and limit epilepsy after brain injury.

Mild Concussion, but Not Moderate Traumatic Brain Injury, Is Associated with Long-Term Depression-Like Phenotype in Mice.

Full Text Available Mild traumatic brain injuries can lead to long-lasting cognitive and motor deficits, increasing the risk of future behavioral, neurological, and affective disorders. Our study focused on long-term behavioral deficits after repeated injury in which mice received either a single mild CHI (mCHI, a repeated mild CHI (rmCHI consisting of one impact to each hemisphere separated by 3 days, or a moderate controlled cortical impact injury (CCI. Shams received only anesthesia. Behavioral tests were administered at 1, 3, 5, 7, and 90 days post-injury (dpi. CCI animals showed significant motor and sensory deficits in the early (1-7 dpi and long-term (90 dpi stages of testing. Interestingly, sensory and subtle motor deficits in rmCHI animals were found at 90 dpi. Most importantly, depression-like behaviors and social passiveness were observed in rmCHI animals at 90 dpi. These data suggest that mild concussive injuries lead to motor and sensory deficits and affective disorders that are not observed after moderate TBI.

The objective of this study was to determine the prevalence of extrinsic wrist ligament injury by magnetic resonance imaging and its association with intrinsic ligament tears. We reviewed conventional magnetic resonance images performed over a 5-year period from adult patients in the setting of wrist trauma. Two musculoskeletal radiologists examined the integrity of wrist ligaments and presence of bone abnormalities. In a cohort of 75 subjects, extrinsic ligament injury was present in 75%, with radiolunotriquetral being most frequently affected (45%). Intrinsic ligament injury was present in 60%. Almost half of subjects had combined intrinsic and extrinsic ligament injury. Bone abnormalities were seen in 69%. The rate of extrinsic injury was higher in subjects with bone injury (P = 0.008). There is high prevalence of extrinsic ligament injury in the setting of wrist trauma, especially in the presence of bone abnormalities, with combined injury of intrinsic and extrinsic ligaments in about half of cases.

Given the importance of trucking to the economic well being of a country and the safety concerns posed by the trucks, a study of large-truck crashes is critical. This paper contributes by undertaking an extensive analysis of the empirical factors affecting injury severity of large-truck crashes. Data from a recent, nationally representative sample of large-truck crashes are examined to determine the factors affecting the overall injury severity of these crashes. The explanatory factors include the characteristics of the crash, vehicle(s), and the driver(s). The injury severity was modeled using two measures. Several similarities and some differences were observed across the two models which underscore the need for improved accuracy in the assessment of injury severity of crashes. The estimated models capture the marginal effects of a variety of explanatory factors simultaneously. In particular, the models indicate the impacts of several driver behavior variables on the severity of the crashes, after controlling for a variety of other factors. For example, driver distraction (truck drivers), alcohol use (car drivers), and emotional factors (car drivers) are found to be associated with higher severity crashes. A further interesting finding is the strong statistical significance of several dummy variables that indicate missing data - these reflect how the nature of the crash itself could affect the completeness of the data. Future efforts should seek to collect such data more comprehensively so that the true effects of these aspects on the crash severity can be determined. Copyright © 2010 Elsevier Ltd.

The impact of hyperglycemia after traumatic brain injury (TBI), and even the administration of glucose–containing solutions to head injured patients, remains controversial. In the current study adult male Sprague-Dawley rats were tested on behavioral tasks and then underwent surgery to induce sham injury or unilateral controlled cortical impact (CCI) injury followed by injections (i.p.) with either a 50% glucose solution (Glc; 2 g/kg) or an equivalent volume of either 0.9% or 8% saline (Sal) at 0, 1, 3 and 6 h post-injury. The type of saline treatment did not significantly affect any outcome measures, so these data were combined. Rats with CCI had significant deficits in beam-walking traversal time and rating scores (p’s glucose may improve some neurological outcomes and, importantly, the induction of hyperglycemia after isolated TBI did not adversely affect any sensorimotor, cognitive or histological outcomes.

Spinal Cord Injury (SCI) is a devastating situation. Spinal Cord Injury affects functional, psychological and socioeconomic aspects of patients' lives. The ability to accomplish and explicate the one's own and other's feelings and emotions to spread over appropriate information for confirming thoughts and actions is defined as emotional intelligence (EI). The goal of this study was to evaluate depression and EI in SCI patients in comparison with healthy subjects. One-hundred-ten patients with SCI and 80 healthy subjects between Aug 2014 and Aug 2015 were enrolled. The study was conducted in Imam Hospital, Tehran, Iran. All participants were asked to fill valid and reliable Persian version Emotional Quotient inventory (EQ-i) and Beck Depression Inventory (BDI). All data were analyzed using SPSS. Data were presented as Mean±SD for continuous or frequencies for categorical variables. Continuous variables compared by means of independent sample t -test. P -values less than 0.05 were considered as significant. Mean age of patients was 28.7 and mean age of controls was 30.2 yr. Spinal cord injury in 20 (18.3%) were at cervical level, in 83 (75.4%) were thoracic and in 7 (6.3%) were lumbar. Mean values of independence, stress tolerance, self-actualization, emotional Self-Awareness, reality testing, Impulse Control, flexibility, responsibility, and assertiveness were significantly different between cases and controls. Mean values of stress tolerance, optimism, self-regard, and responsibility were significantly different between three groups with different injury level. Most scales were not significantly different between male and female cases. Emotional intelligence should be considered in SCI cases as their physical and psychological health is affected by their illness.

On the hasis of analysis of roentgenograms, tomograms, and bronchograms in 189 patients a repeated study was made of the X-ray semiotics of radiation affections of the lungs. The leading roentgenological symptom of radiation affections of the lungs irrespective of their primary localization, was linear deformity and intensification of the broncho-vascular patten in the peripheral zone. This was expressed on roentgenograms in the form of radially- and cross- coursing shadows from the root: tomog.raphically it was manifested in narrowed shadows of the vessels, a change of their course, their approximation and a tendency to approach the centre; analogous disturbances of topography of the bronchi with phenomena of deforming bronchitis were seen in bronchography. A significant si.gn of radiation injuries of the lung tissue is a tendency to progressive development of connective tissue, which was expressed roentgenologically in extensive pneumosclerosis, sometimes with an outcome into fibrothorax with marked topographic disturbances. Radiation injuries are accompanied by an adhesive reaction of the pleura

A preconditioning nerve lesion inhibits mechanical pain hypersensitivity following subsequent neuropathic injury

Directory of Open Access Journals (Sweden)

2011-01-01

Full Text Available Abstract Background A preconditioning stimulus can trigger a neuroprotective phenotype in the nervous system - a preconditioning nerve lesion causes a significant increase in axonal regeneration, and cerebral preconditioning protects against subsequent ischemia. We hypothesized that a preconditioning nerve lesion induces gene/protein modifications, neuronal changes, and immune activation that may affect pain sensation following subsequent nerve injury. We examined whether a preconditioning lesion affects neuropathic pain and neuroinflammation after peripheral nerve injury. Results We found that a preconditioning crush injury to a terminal branch of the sciatic nerve seven days before partial ligation of the sciatic nerve (PSNL; a model of neuropathic pain induced a significant attenuation of pain hypersensitivity, particularly mechanical allodynia. A preconditioning lesion of the tibial nerve induced a long-term significant increase in paw-withdrawal threshold to mechanical stimuli and paw-withdrawal latency to thermal stimuli, after PSNL. A preconditioning lesion of the common peroneal induced a smaller but significant short-term increase in paw-withdrawal threshold to mechanical stimuli, after PSNL. There was no difference between preconditioned and unconditioned animals in neuronal damage and macrophage and T-cell infiltration into the dorsal root ganglia (DRGs or in astrocyte and microglia activation in the spinal dorsal and ventral horns. Conclusions These results suggest that prior exposure to a mild nerve lesion protects against adverse effects of subsequent neuropathic injury, and that this conditioning-induced inhibition of pain hypersensitivity is not dependent on neuroinflammation in DRGs and spinal cord. Identifying the underlying mechanisms may have important implications for the understanding of neuropathic pain due to nerve injury.

Traumatic brain injury (TBI) can cause widespread and prolonged brain degeneration. TBI can affect cognitive function and brain integrity for many years after injury, often with lasting effects in children, whose brains are still immature. Although TBI varies in how it affects different individuals, image analysis methods such as tensor-based morphometry (TBM) can reveal common areas of brain atrophy on magnetic resonance imaging (MRI), secondary effects of the initial injury, which will differ between subjects. Here we studied 36 pediatric moderate to severe TBI (msTBI) participants in the post-acute phase (1-6 months post-injury) and 18 msTBI participants who returned for their chronic assessment, along with well-matched controls at both time-points. Participants completed a battery of cognitive tests that we used to create a global cognitive performance score. Using TBM, we created three-dimensional (3D) maps of individual and group differences in regional brain volumes. At both the post-acute and chronic time-points, the greatest group differences were expansion of the lateral ventricles and reduction of the lingual gyrus in the TBI group. We found a number of smaller clusters of volume reduction in the cingulate gyrus, thalamus, and fusiform gyrus, and throughout the frontal, temporal, and parietal cortices. Additionally, we found extensive associations between our cognitive performance measure and regional brain volume. Our results indicate a pattern of atrophy still detectable 1-year post-injury, which may partially underlie the cognitive deficits frequently found in TBI.

The etiology of running-related injury is important to consider as the effectiveness of a given running-related injury prevention intervention is dependent on whether etiologic factors are readily modifiable and consistent with a biologically plausible causal mechanism. Therefore, the purpose of the present article was to present an evidence-informed conceptual framework outlining the multifactorial nature of running-related injury etiology. In the framework, four mutually exclusive parts are presented: (a) Structure-specific capacity when entering a running session; (b) structure-specific cumulative load per running session; (c) reduction in the structure-specific capacity during a running session; and (d) exceeding the structure-specific capacity. The framework can then be used to inform the design of future running-related injury prevention studies, including the formation of research questions and hypotheses, as well as the monitoring of participation-related and non-participation-related exposures. In addition, future research applications should focus on addressing how changes in one or more exposures influence the risk of running-related injury. This necessitates the investigation of how different factors affect the structure-specific load and/or the load capacity, and the dose-response relationship between running participation and injury risk. Ultimately, this direction allows researchers to move beyond traditional risk factor identification to produce research findings that are not only reliably reported in terms of the observed cause-effect association, but also translatable in practice. © 2017 John Wiley & Sons A/S.

Full Text Available Objectives: Thoracic injury is a challenge to the thoracic surgeon practicing in developing countries. This prospective study was conducted to see the mode of injury, injury types and overall outcome of thoracic injury in our settings. Materials and methods: This prospective study was conducted in 100 thoracic injury patients between December 2011 to June 2012. The demographic features, type of the trauma, radiological assessment, associated organ injuries, management of the injury, surgical interventions, morbidity, mortality, length of hospital stay were analysed. Results: In this study the ages ranged from 7 to 84 years. There were 73 (73% males and 27 (27% females. The majority of patients (83% were injured during the evening and night time. The majority of patients 92(92% sustained blunt chest injuries. The mechanism of injury was not significantly associated with length of hospital stay (P > 0.05 and mortality (P > 0.05.Road traffic accident was the most common cause of injuries affecting 68(68% of patients followed by fall injury of 19(19%. Rib fractures, haemothorax, pneumothorax and lung contusion were the most common type of injuries accounting for 83.0%, 57%,34% and 33% respectively. Associated extra-thoracic injuries were noted in 64.0% of patients. 45(45% of the cases of haemothorax, pneumotharax and haemopneumothorax were treated by tube thoracotomy.

An evidence base for the management and prevention of shoulder injuries in soccer is lacking. The aim of this study was to demonstrate the type, mechanism and recovery time after surgery associated with serious shoulder injuries sustained in professional soccer to build an evidence base foundation. Fifty-two professional soccer players underwent shoulder surgery for injuries sustained during match play. Of these, 25 fulfilled the inclusion criteria. Data were collected for injury mechanism and type; clinical, radiological and surgical findings and procedures; and return to full participation. Subjects were all managed by the same surgeon. Labral injuries represented the most common injury type affecting 21 (84 %) subjects; two rotator cuff (8 %) and two combined labral/rotator cuff (8 %) injuries were less common. Fourteen (56 %) subjects sustained a high-energy trauma injury in a combined abduction and external rotation position. Six (24 %) subjects sustained a low-energy trauma mechanism in variable positions, while five (20 %) had a gradual onset of symptoms. Twenty-two (88 %) subjects reported a dislocation as a feature of their presentation. All of the subjects with high- and low-energy trauma mechanisms reported a dislocation occurring at the time of injury. Eight (32 %) subjects had sustained a previous significant shoulder injury to the ipsilateral side. Goalkeepers did not sustain low-energy trauma injuries. Outfield players returned to full participation in a mean time of 11.6 weeks, while goalkeepers did so in 11.1 weeks post-surgery. Return to participation time ranged from 7 to 24 weeks with a median of 11 weeks. Professional soccer players can expect a return to participation within 12 weeks post-surgery. The majority of serious shoulder injuries in soccer occur at a positional extreme of external rotation and abduction in high-energy situations, while a significant number occur in low-energy situations away from this position. Most serious shoulder

To determine the type and number of injuries that occur during the training and practice of Muay Thai kick boxing and to compare the data obtained with those from previous studies of karate and taekwondo. One to one interviews using a standard questionnaire on injuries incurred during training and practice of Muay Thai kick boxing were conducted at various gyms and competitions in the United Kingdom and a Muay Thai gala in Holland. A total of 152 people were questioned, 132 men and 20 women. There were 19 beginners, 82 amateurs, and 51 professionals. Injuries to the lower extremities were the most common in all groups. Head injuries were the second most common in professionals and amateurs. Trunk injuries were the next most common in beginners. The difference in injury distribution among the three groups was significant (pinjury in the three groups. Fractures were the second most common in professionals, and in amateurs and beginners it was sprains and strains (pinjury rates were: beginners, 13.5/1000 participants; amateurs, 2.43/1000 participants; professionals, 2.79/1000 participants. For beginners, 7% of injuries resulted in seven or more days off training; for amateurs and professionals, these values were 4% and 5.8% respectively. The results are similar to those found for karate and taekwondo with regard to injury distribution, type, and rate. The percentage of injuries resulting in time off training is less.

Road traffic injury surveillance involves methodological difficulties due, among other reasons, to the lack of consensus criteria for case definition. Police records have usually been the main source of information for monitoring traffic injuries, while health system data has hardly been used. Police records usually include comprehensive information on the characteristics of the crash, but often underreport injury cases and do not collect reliable information on the severity of injuries. However, statistics on severe traffic injuries have been based almost exclusively on police data. The aim of this paper is to propose criteria based on medical records to define: a) "Hospital discharge for traffic injuries", b) "Person with severe traffic injury", and c) "Death from traffic injuries" in order to homogenize the use of these sources.

Although sleep-wake disturbances are prevalent and well described after traumatic brain injury, their pathophysiology remains unclear, most likely because human traumatic brain injury is a highly heterogeneous entity that makes the systematic study of sleep-wake disturbances in relation to trauma-induced histological changes a challenging task. Despite increasing interest, specific and effective treatment strategies for post-traumatic sleep-wake disturbances are still missing. With the present work, therefore, we aimed at studying acute and chronic sleep-wake disturbances by electrophysiological means, and at assessing their histological correlates after closed diffuse traumatic brain injury in rats with the ultimate goal of generating a model of post-traumatic sleep-wake disturbances and associated histopathological findings that accurately represents the human condition. We assessed sleep-wake behavior by means of standard electrophysiological recordings before and 1, 7, and 28 days after sham or traumatic brain injury procedures. Sleep-wake findings were then correlated to immunohistochemically labeled and stereologically quantified neuronal arousal systems. Compared with control animals, we found that closed diffuse traumatic brain injury caused increased sleep need one month after trauma, and sleep was more consolidated. As histological correlate, we found a reduced number of histamine immunoreactive cells in the tuberomammillary nucleus, potentially related to increased neuroinflammation. Monoaminergic and hypocretinergic neurotransmitter systems in the hypothalamus and rostral brainstem were not affected, however. These results suggest that our rat traumatic brain injury model reflects human post-traumatic sleep-wake disturbances and associated histopathological findings very accurately, thus providing a study platform for novel treatment strategies for affected patients.

Mountain biking has become an increasingly popular recreational and competitive sport with increasingly recognized risks. The purpose of this study was to review a population based approach to serious injuries requiring trauma center admission related to mountain biking, identify trends and develop directions for related injury prevention programs. Three trauma centers in the Greater Vancouver area exclusively serve a major mountain bike park and the North Shore Mountains biking trails. The Trauma Registries and the patient charts were reviewed for mountain bike injuries from 1992 to 2002. The data were analyzed according to demographics, distribution, and severity of injuries, and need for operative intervention. Findings were reviewed with injury prevention experts and regional and national mountain-biking stakeholders to provide direction to injury prevention programs. A total of 1,037 patients were identified as having bicycling-related injuries. Of these, 399 patients sustained 1,092 injuries while mountain biking. There was a threefold increase in the incidence of mountain biking injuries over a 10-year period. Young males were most commonly affected. Orthopedic injuries were most common (46.5%) followed by head (12.2%), spine (12%), chest (10.3%), facial (10.2%), abdominal (5.4%), genitourinary (2.2%), and neck injuries (1%). High operative rate was observed: 38% of injuries and 66% of patients required surgery. One patient died from his injuries. Injury prevention programs were developed and successfully engaged the target population. Mountain biking is a growing cause of serious injuries. Young males are principally at risk and serious injuries result from intended activity and despite protective equipment. Injury prevention programs were developed to address these concerns.
