RESUMO
OBJECTIVE To analyze the clinical characteristics of pulsatile tinnitus induced by sigmoid sinus abnormalities in high and normal intracranial pressure states.METHODS There were 66 patients of pulsatile tinnitus induced by sigmoid sinus abnormalities,including 55 cases of sigmoid sinus wall dehiscence and 11 cases of sigmoid sinus diverticulum.The index of transverse sinus stenosis(ITSS)was used to assess intracranial pressure in magnetic resonance venography(MRV).We obtained 41 cases in intracranial hypertension group and 25 cases in normal intracranial pressure group.The age,gender,handedness,tinnitus lateralization,mean arterial pressure(MAP),body mass index(BMI),tinnitus duration,tinnitus frequency,tinnitus loudness,tinnitus handicap inventory(THI)and blood biochemical examination were recorded to analyze.RESULTS The BMI was 24.98 kg/m2(22.87 kg/m2,28.46 kg/m2)and 24.01 kg/m2(20.34 kg/m2,25.03 kg/m2)and THI score was 45.59±23.47 and 33.84±20.13 in intracranial hypertension group and normal intracranial pressure group,respectively.Compared with normal intracranial pressure group,the BMI and THI of intracranial hypertension group were significantly increased(P was 0.047 and 0.042 respectively).No significant difference were found in other indicators.CONCLUSION There are some different characteristics in pulsatile tinnitus induced by sigmoid sinus abnormalities in high and normal intracranial pressure states,which manifest obviously increased BMI and THI score in pulsatile tinnitus patients with intracranial hypertension.
RESUMO
Objective To compare the differences in curative effect between general treatment model and stroke unit model in the treatment of stroke in the elderly inpatients, to explore the standardized management model, for improving efficacy and reducing the degree of invalidity and mortality. Methods A total of 1200 cases with acute cerebrovascular disease were admitted into our department from April 2002 to April 2007. All patients were randomly assigned either into stroke unit or general ward to receive treatment, and the data of two groups were compared. The key indexes included mortality, hospitalization time, Barthel Index (BI), National Institutes of Health Stroke Scale (NIHSS) and Oxford Handicap Scale (OHS). All the patients or their family members were asked to have the Visual Analogue Scales (VAS). The data of cost and effect were analyzed with SPSS software. Results The complication rate and mortality rate were significantly lower in stroke unit group than in general ward group (P＜ 0.01). The scales of BI, NIHSS, OHS and VAS were significantly better in stroke unit group than in general ward group when discharged (P＜0.05). The hospitalization time was shorter in stroke unit group than in general ward group (P＜0.05). There was no significant difference in the costs of hospitalized patients between the two groups (P＞0.05).Conclusions Stroke unit model can improve the physical activity and life quality of patients and reduce disease mortality without increasing the cost of patients.
