RÉSUMÉ
Objective To compare the prognostic role of MRI scan,CT scan and physical check-up in the brainstem injury.Methods Twenty-one patients with craniocerebral injury,appearing disturbance of consciousness,were performed MRI scan,CT scan and physical check-up to exclude brainstern injury under airway unobstructed condition;their results were compared and analyzed.Results In all of these patients,17 showed brainstern injury symptoms.Tracheotomy was performed in 14 and decompression of cerebral contusion and removal of intracranial hematoma was performed in 7.CT examination was adopted in all the patients:low-density shadow in hrainstem region and catholicity subarachnoid hemorrhage was found in 9 and 7,respectively;gently subarachnoid hemorrhage or no obvious brainstem change was noted in 5.MRI scan showed that 15 patients were diagnosed as having brainstem injury and 6 were base of skull or hemisphere region injuries.Conclusion MRI scan,which is better than CT scan and physical check-up,can help to make a definite diagnosis in brainstem injury.
RÉSUMÉ
Objective To monitor the prevalence of Keshan disease in Huangling County, Shaanxi Previnee in 2007. Methods All local residents in surveinance area of Keshan disease in Diantou and Yaoping Township of Huangling County, were surveyed and given overall examinations by electrocardiography. The patients of latent and chronic Keshan disease were examined by X-ray. The selenium contents in blood and hair were monitored by fluorospectrophotometry in surveillance and non-surveillance areas. Results No new ease of acute or sub-acute patient was found. Latent and chronic patients detected accounted for 3.92% (35/893). Only 1 ease of new latent Keshan disease was newly found. Major feature of electrocardiographic abnormality was ST-T change. By X-ray, there were 27 eases with a normal heart, 20 eases with mild enlargement, 20 eases with medium enlargement, and 16 eases with marked enlargement. Serological selenium eoncentrations were (38.67±19.58), (48.55±22.36), (67.29±17.32)μg/L, respectively in patients, internal and external eontrols(F=16.291 ,P<0.01). Selenium contents of children's hair were (0.376±0.101), (0.372±0.085), (0.436±0.085)μg/L, respectively(F= 17.032, P<0.01). Conclusions Cases of diagnosed Keshan disease were decreased compared with the previous years. There were new eases of latent Keshan disease in Huangling County, Shaanxi Province.
