METHODS： A cross-sectional,multi-center,observational study.Patients with an injured eye who visited the Emergency Department at one of nine hospitals in Korea were enrolled.All data were prospectively collected between March and September 2010 using a questionnaire.Eye injuries that occurred during risky sports were examined by gender and age.Additionally,the rate of open globe injuries that occurred with and without protective eyewear was examined for each activity.Continuous variables were compared using Student＇s t-test and categorical variables were compared using Chi-square test.RESULTS： A total of 446 patients had sports-related eye injuries.Teenagers（10-19 years old） and young adults（20-29 years old） had the most eye injuries.Eye injuries accounted for 0.2% of Emergency Department patients.Baseball was the most common cause of sports-related eye injuries,followed by soccer and hiking.Protective gear was worn by 9.4% of all patients.Patients that were 30-39 years of age had the highest rate of protective gear use,followed by patients that were 40-49 years of age.The proportion of sports-related eye injuries that were open-globe injuries was highest for soccer and hiking.CONCLUSION： Although injuries were most common in patients below the age of 10 years,these patients had the lowest rate of protective eyewear use.Injuries in adults over 40 years of age most commonly occurred during hiking,but the rate of protective eyewear use was low.Young athletes should be educated on and provided with protective eyewear and policies protective gear use should be established.For older adults,eye protection should be encouraged,especially during hiking.展开更多

This research was conducted to examine the frequency of sports- related injuries referring to Kashan University of Medical Sciences Trauma Research Center from 2005 to 2011. Methods： This was a retrospective research in which existing data from the data bank of Kashan University of Medical Sciences Trauma Research Center were employed. The data were extracted from the main source by SPSS version 16.0. Variables such as age, education, occupation and gender were analyzed. Results： The highest proportion of injuries was observed in students （59.4%） followed by workers （11.8%）. Upper and lower extremities were most commonly injured. The most frequent injury was strain （35.4%）, followed by sprain （27.7%）. Conclusion： The results of this research showed that the majority of the sports trauma occurrs in students; therefore, they need more attention in regard to sports injuries. Preventive measures such as informing the coaches and teachers as well as increasing the students＇ awareness about the injury risk can decrease the incidences of sports injuries.展开更多

Many clinicians have noted that yoga may result in knee problems, which though requires more researches to corroborate. This investigation was conducted to ascertain the relationship between yoga and meniscus injury as well as the extent of impairment ac- cording to variant yoga practice periods. Methods： Totally 819 women aged 20-49 years who practiced yoga or other popular sports including badminton, jogging, climbing hills, etc for at least one hour per day were selected to participate in this research. These subjects were required to complete a questionnaire and receive relevant physical examination. Magnetic resonance （MR） scan of the knee was recommended for the suspicioussubjects for ultimate diagnosis. The subject with abnormal meniscus MR signals was defined as a case and matched with two controls in terms of age and body mass index （BMI）. Altogether there were 273 cases and 546 controls. The nested casecontrol model was adopted to assess the risk of meniscus injury between variant exposures in practicing yoga and several other popular sports. Moreover, the 181 yoga subjects were subdivided into three groups according to different exercise durations, followed by further analysis with the variables of age, BMI and Lysholm score. Results： Yoga was found associated with a higher risk （P=0.008, 0R=1.621） of meniscus injury compared with badminton, jogging and climbing hills. The three yoga sub- groups showed statistical difference between each other in terms of Lysholm score （P=0.027） and BMI （P=0.003）. The subjects with longer-term yoga practice had lighter weight but lower Lysholm scores. Conclusions： Yoga perhaps exerts destructive impact on the meniscus for Chinese women, yet it needs further verifications, Furthermore, the female yoga players with longer exercise duration are more susceptible to meniscus injury though they can become leaner.展开更多

Neurological examination revealed that the patient＇s muscle power was 0/5 at all extremities. The patient did not show any sense of light touch or pain in his extremities. In radiological studies, cervical spine X-ray and CT scan images showed C4-C5 subluxation with bilateral locked facets and spinal cord injury. The results of this very rare case study revealed that exercising Parkour sport without taking into account safety standards could result in irreversible injuries to the cervical spinal cord with fatal outcome.展开更多
