ABSTRACT
BACKGROUND: Weather conditions are thought to increase the risk of stroke occurrence. But their mechanism has not yet been clarified. We investigated possible relationships between ischemic stroke and weather conditions including atmospheric pressure, temperature, relative humidity, and wind speed. METHODS: One hundred and twenty-eight patients with ischemic stroke who had been admitted to our hospital between January 1 and December 31, 2010 were enroled in this study. We investigated the relationship between daily cases and weather conditions the same day or 1, 2, and 3 days before stroke. RESULTS: A negative correlation was found between maximum wind speed and daily cases 3 days before stroke. As the relationship between daily cases and changes of weather conditions in consecutive days was evaluated, a negative correlation was found between daily cases and change of atmospheric pressure in the last 24 hours. CONCLUSIONS: The maximum wind speed 3 days before stroke and change of atmospheric pressure in the last 24 hours were found to increase the cases of ischemic stroke. We recommend that individuals at risk of ischemic stroke should pay more attention to preventive measures, especially on days with low maximum wind speed, on subsequent 3 days, and on days with low atmospheric pressure in the last 24 hours.
ABSTRACT
BACKGROUND: Traumatic bilateral hip dislocation is a rare condition. Anterior shoulder dislocation combined with this condition is even a rare occurrence. A 57-year-old man had bilateral asymmetric hip dislocation with a posterior wall fracture of the left acetabulum associated with right shoulder anterior dislocation caused by falling down from a cherry tree. Traumatic hip dislocation and anterior shoulder dislocation represent a true orthopedic emergency. METHODS: Closed reduction was performed immediately for three of the dislocated joints. Posterior wall fracture of the left acetabulum was treated with open reduction and internal fixation by screws. Because of the severity of associated complications like aseptic necrosis or posttraumatic osteoarthritis, efforts were made to ensure prompt diagnosis, therapy and prognosis. RESULTS: The patient was successfully treated by open reduction and internal fixation of the left acetabulum, and discharged from the hospital. CONCLUSION: Traumatic asymmetric hip dislocation and anterior shoulder dislocation are an orthopedic emergency and early diagnosis with immediate reduction of the dislocation is the key determinants of excellent result of treatment.
