RESUMO
OBJECTIVES: To evaluate gait characteristics and investigate changes pre- and post- cerebrospinal fluid tap test (CSF TT) in gait parameters in patients with probable idiopathic normal pressure hydrocephalus (iNPH). METHODS: Sixty patients were sequential circuited and diagnosed with possible iNPH according to Japanese second iNPH guidelines at our hospital from December 2016 to March 2021. All patients underwent the CSF TT. Gait parameters, cognitive and urinary function were assessed pre- and post-CSF TT. Patients who were unable to ambulate to take the tests or could not walk independently or walked normally were excluded. RESULTS: Twenty-six patients were diagnosed with probable iNPH using the CSF TT. After CSF TT, the Boon sum score improved from 20.0 ± 7.7-16.6 ± 8.0 (p < 0.001), the Boon walking score improved from 8.9 ± 3.5-7.8 ± 4.4 (p = 0.008), the Boon step score improved from 6.3 ± 2.3-5.2 ± 2.1 (p < 0.001), the Boon time score improved from 4.9 ± 2.4-3.7 ± 2.3 (p < 0.001), tandem walking disturbance improved from 1.7 ± 0.7-1.4 ± 0.9 (p = 0.043), tendency toward falling improved from 1.7 ± 0.7-1.3 ± 1(p = 0.022), 3-meter timed up and go test (3-mTUG) improved from 21.9 ± 7.1-17.6 ± 5.1( p < 0.001), 10-meter walking (10-MWT) step improved from 31.1 ± 13.1-24.6 ± 7.5 (p < 0.001), velocity improved from 0.7 ± 0.2-0.8 ± 0.3 (p < 0.001) and stride length improved from 0.4 ± 0.1-0.46 ± 0.1(p < 0.001), compared with before the CSF TT. CONCLUSION: These results suggest that many parameters in the Boon gait test were responsive to the CSF TT, and the Boon gait test may help objectify response to the CSF TT by combining the 10-MWT and 3-mTUG gait assessments.

Objective:To study the efficacy and safety of Methazolamide(MTZ)for the treatment of normal pressure hydrocephalus(NPH)patients.Methods:A randomized, double-blind, placebo-controlled, prospective clinical study was conducted in Aviation General Hospital.A total of 35 NPH patients including 29 idiopathic normal pressure hydrocephalus(iNPH)and 6 secondary normal pressure hydrocephalus(sNPH)received drug treatment in our hospital from September 2019 to March 2021.All patients were unsuitable for or refused surgical treatment for some reasons.The patients were divided into drug group(n=18)and control group(n=10), taking oral MTZ or placebo 25 mg twice daily, increasing to 50 mg twice daily after 1 week if there was no discomfort.The 10 m gait score, cognitive function score, brain MRI check were completed before and 1 month after oral administration.The assessment of idiopathic normal pressure hydrocephalus scale(iNPHGS)score were performed 1 month and 3 months after oral administration.The primary efficacy endpoint was iNPHGS score for 3 months treatment and the secondary efficacy endpoint was the assessment of above scales for 1 month treatment.Results:As compared with baseline, the effect of 1 month treatment showed that MOCA scores[(16.2±8.8)and(14.8±8.7)scores, t=-2.68, P=0.02], 10 m gait scores[(22.3±11.2)and(25.6±12.9), t=2.76, P=0.02], iNPHGS scores[(7.3±3.2)and(8.1±3.5), t=4.08, P<0.01]were improved.The effect of 3 month treatment showed that the iNPHGS score(6.1±2.4)was improved compared with baseline( t=5.07, P<0.01)and 1 month( t=4.11, P<0.01). But the above scores of the control group were not significantly improved compared with the baseline(all P>0.05). After 1 month treatment, the 10 m gait score and iNPHGS score in the drug group were improved compared with those in the control group(all P<0.05). After 3 months treatment, the iNPHGS score was improved compared with the baseline level in the control group( t=-4.41, P<0.05). The above 35 patients had no serious adverse reactions such as hypokalemia and acidosis.There was no significant difference in adverse events between the two groups( χ2=0.01, P=1.00). Conclusions:The treatment of MTZ could effectively improve the clinical symptoms of NPH patients with good safety.
RESUMO
Objective:To investigate the features of gait disorders in patients with idiopathic normal pressure hydrocephalus(iNPH).Methods:Clinical data of 42 patients diagnosed with iNPH admitted to the neurological department of Aviation General Hospital from March 2017 to July 2020 were consecutively collected.The features of gait disturbance and activity of daily living were retrospectively studied.Results:Of the 42 patients, 29 cases(69%)were males, aged(73.0±8.3)years, and 13 cases were females, aged(73.0±8.3)years old.The mean course of disease was(3.5±3.0)years.There were 90.5% of patients(38/42)complained of gait disorders, and 61.9%(26/42)had fall histories.All patients had gait abnormalities.The time for 3m-Timed Up and Go(TUG)test were(27.8±17.0)seconds, and the proportion of patients with the time for 3m-TUG less than 10 seconds, 10~20 seconds and more than 20 seconds were 5.9%(2/34), 35.3%(12/34)and 58.8%(20/34), respectively.In the 10-meter walking test, 8 patients needed assistance.Of the 34 patients who could walk independently, 94.1%(32/34)had tandem walking disturbed and tendency toward falling, 76.5%(26/34)had turning disturbed, 44.1%(15/34)had wide based stride and small steps, 29.4%(10/34)had trunk balance disturbed, 23.5%(8/34)had reduced foot-floor clearance, and 8.8%(3/34)had start hesitation, 97.6%(41/42)had abnormal step counting and 90.5%(38/42)had abnormal time evaluation.The proportion of patients with activity of daily living(Barthel Index)scores of(mild dependence), moderate dependence and severe dependence were 71.4%(30/42), 28.6%(12/42)and 0%(0/42). Of the 30 patients with mild dependence, 56.7%(17/30)had fall histories.Conclusions:In our study, all patients have gait dysfunction, which causes some impact on activity of daily living and a higher risk of falls.Gait slowness, tandem walking disturbed, turning disturbed, tendency toward falling, wide based stride and small steps are the most involved gait characteristics.Early assessment of gait disorders is of great significance in early diagnosis and the prevention of falls and living ability decline.
RESUMO
Total 1350 subjects were selected by cluster random sampling from Chongwen District and Shijingshan District in Beijing with a populations of 100 000.Chongwen District represented a typical urban district and Shijingshan represtnted a newly extended urban district.Qualified investigators conducted face-to-face survey using the uniform questionnaire and measurement, dealing with the knowledge, attitude and behavior for risk factors of stroke in two districts.The results showed:in Chongwen District, the awareness rates of "the diagnostic criteria of hypertension", "antihypertensive drugs can lower the risk of cardiocerebral vascular disease", and "criteria for obesity" were 71.3%, 87.3% and 22.9% respectively,which were significantly higher than those in Shijingshan District.The awareness rate of "bad temper may increase the risk of cardiocerebral vascular disease" was lower in the Chongwen District.There were no significant differences in attitude between two districts.In Chongwen District the level of three risk factors (smoking and obesity) was significantly lower than Shijingshan, but action of self-examination was also significantly lower.Generally, there was higher level in health knowledge and lower level of risk factors in Chongwen District.The hypertension-related knowledge and behavior was not entirely consistent.It is necessary to transform knowledge into behavioral changes or intervention of risk factors in population with high awareness like Chongwen District.
RESUMO
The metabolic syndrome (MetS) is a general name for a group of metabolic risk factors for cardiovascular diseases,and its major constituents include hyperglycemia,hypertension,lipid abnormality and central obesity.Because MetS portly overlaps the risk factors of stroke,and thus it determines that MetS is closely related with stroke.No matter the interaction of all individual risk factor or multiple risk factors may affect the occurrence and development of stroke.
