Little is known about the possible pathomechanisms and the clinical course.METHODS： Secondary sclerosing cholangitis was diagnosed in five patients with persistent jaundice after severe trauma （one burn injury, three accidents, one power current injury）. Medical charts were retrospectively reviewed with regard to possible trigger mechanisms for cholestasis, and the clinical course was recorded.RESULTS： Diagnosis of secondary sclerosing cholangitis was based in all patients on the primary sclerosing cholangitis （PSC）-Iike destruction of the intrahepatic bile ducts at cholangiography after exclusion of PSC. In four patients, arterial hypotension with subsequent ischemia may have caused the bile duct damage, whereas in the case of power current injury direct thermal damage was assumed to be the trigger mechanism. The course of secondary liver fibrosis was rapidly progressive and proceeded to liver cirrhosis in all four patients with a follow-up 〉2 years. Therapeutic possibilities were limited.CONCLUSION： Posttraumatic sderosing cholangitis is a rare but rapidly progressive disease, probably caused by ischemia of the intrahepatic bile ducts via the peribiliary capillary plexus due to arterial hypotension.Gastroenterologists should be aware of this disease in patients with persistent cholestasis after severe trauma.展开更多

Methods: 354 students from gymnastic department and 429 from nongymnastic department with knee joint pain were selected. 184 students from gymnastic department and 342 from nongymnastic department were checked randomly by a surgeon. 77 patients (37 males, 40 females) from gymnastic department and 119 patients (62 males, 57 females) from nongymnastic department were diagnosed as chondromalacia patellae. The amount of exercise and the occurrence of sports injury were investigated in each student. All data were analyzed with SPSS 10.0 statistical software. Results: The prevalence of chondromalacia patella was 20.1% in female students and 11.6% in male students from gymnastic department, and 5.61% in female students and 4.92% in male students from nongymnastic department. The amount of exercise and the occurrence of sports injury to the knee joint in students from gymnastic department were greater than those from nongymnastic department. Conclusions: In both female and male students, the prevalence of chondromalacia patella is higher in gymnastic department than nongymnastic department. Sports injury is an important cause of chondromalacia patella.展开更多

Methods: Two police teams of traffic management in downtown, two teams in suburb, one team in county and one freeway team were randomly selected, and road traffic crashes between 1988 and 1997 were investigated and analyzed. Results: A total of 13121 road traffic crashes with 6201 crashes with casualties were analyzed. The incidence of crashes was higher in May, June and July, and on Friday and Wednesday and at 8:00-12:00 and 14:00-18:00 within a day. Casualties were 44.0% in pedestrians and 42.5% in passengers of total casualties. The deaths and severe injuries in pedestrians were 59.1% of total deaths and 56.4% of total severe injuries. The age of drivers and passengers were mainly at 18-30 years, followed by 31-40 years. People over 60 years old accounted for 24.1% of total pedestrian casualty. Head injury was the most common reason for deaths. The main reasons for these crashes were improper driving and violating traffic laws. Violating traffic laws by pedestrian was one of the main reasons for pedestrian casualty. Conclusions: The crashes are related to the characteristics of geography, climate, society activity of people, and the sense of traffic safety, the basic traffic construction and management in Chongqing. The traffic casualty of pedestrian is a big problem in Chongqing. To prevent and decrease road traffic injuries effective methods should be worked out and propaganda on traffic safety and traffic management should be strengthened according to different characteristics of different regions. To strengthen the first aid and treatment of cranium-brain injury and chest-back injury is also helpful in decreasing traffic deaths.展开更多

The pathophysiology of this complicated phenomenon has been focused on in recent years. Tissue injury and hypoperfusion, activated protein C and Complements play important roles in the early phase after trauma. While the use of blood products, hypothermia, acidosis and inflammation are the main mechanism in late phase. Supplementing coagulation factors and platelets to improve ACoTS are inefficient. Only positive resuscitation from shock and improving tissue hypoperfusion have expected benefits.展开更多

Treatment of these patients is still a major problem in health care system. The aim of current study was to assess the epidemiology of livestock-related injuries in a major trauma center in Iran from 2006 to 2011. Methods： In a prospective study, patients with live- stock-related injuries who were consecutively admitted to the trauma center in Kashan, Iran between 2006 and 2011 were evaluated. The data collected included patient＇s demographics, place and nature of accident, damaged organ, educational level, transport and outcome. Data were expressed as mean±standard deviation. Results： A total of 129 patients were included in this study, accounting for 0.3% of all trauma admission （40 273 cases）. The mean age was （55.27±14.45） years. Men were affected four times more than women. Falling down from livestock is the main mechanism of trauma in all groups. Upper and lower extremities were most frequently injured （n=72）, followed by the head, neck and spine （n=33 for each）. There was one death resulting from livestock-related injury in this study. Conclusion： Despite the low incidence, livestock-related injuries can damage major organs of human body and therefore appropriate training program to increase the safety awareness in home and outdoor is very important.展开更多
