Valor de la escala ASPECTS de circulación posterior y del índice puente-mesencéfalo en imágenes de TC sin contraste y angiografía por TC en pacientes con oclusiones de la arteria basilar recanalizados tras trombectomía mecánica

Purpose

Endovascular treatment with mechanical thrombectomy devices demonstrated high recanalization rates but functional outcome did not correlate with high rates of recanalization obtained. Patient selection prior to the endovascular treatment is very important in the final outcome of the patient. The primary aim of our study was to evaluate the prognostic value of posterior circulation Alberta Stroke Program Early CT Score (pc-ASPECTS) and Pons-Midbrain Index (PMI) scores in patients with Basilar Artery Occlusion (BAO) treated with successful angiographic recanalization after mechanical thrombectomy.

Buscando o motivo da instabilidade hemodinâmica: relato de caso sobre o papel do ultrassom intraoperatório

Background and objectives

A prompt and effective management of trauma patient is necessary. The aim of this case report is to highlight the importance of intraoperative echocardiography as a useful tool in patients suffering from refractory hemodynamic instability no otherwise explained.

Influence of luminal stenosis in aneurysmal and non-aneurysmal blunt cerebrovascular injury

Background

Current blunt cerebrovascular injury (BCVI) grading grossly differentiates injury characteristics such as luminal stenosis (LS) and aneurysmal disease. The effect of increasing degree of LS beyond the current BCVI grading scale on stroke formation is unknown.

Tedium vitae in stroke survivors: a comparative cross-sectional study

Objectives: Suicide is best studied by deconstructing the psychological experiences preceding suicidal death. We assessed the characteristics of tedium vitae (feeling tired of life) after first ever stroke in Nigerian survivors.

Methods: Using the Schedule for Clinical Assessment in Neuropsychiatry, tedium vitae was assessed in 130 stroke survivors attending rehabilitation in a large Nigerian university hospital. Global cognitive and executive dysfunctions were evaluated, respectively, using the Mini Mental State Examination and the modi?ed Indiana University Token test. All participants had their index stroke 3 to 24 months before recruitment into the study. We also examined a comparative group of 130 age, gender, and education matched apparently normal persons who were unrelated to the stroke survivors. Associations were explored using univariate and multivariate logistic regression analyses.

Results: Tedium vitae was experienced by 16 (12.3%) stroke survivors compared with 5 (3.9%) in the comparative group (O. R = 3.5, 95% C. I = 1.3–9.9, p = 0.018). Among stroke survivors, those who were retired were more likely to experience tedium vitae (56.2%, p = 0.045). In analyses adjusting for the effect of systemic hypertension, cognitive dysfunction, retirement and marital separation, there was a 3.5-fold increase in the odds of experiencing tedium vitae after surviving a stroke (O. R = 3.5, 95% C. I = 1.1–11.6, p = 0.042).

Conclusions: Tedium vitae is a common suicidal experience after stroke and may be among the earliest perceptible pointer to impending poststroke suicide. It is easy to assess and may be less costly to obtain an adequate sample size in studies aiming to understand the phenomenon of suicide in the stroke population.     

Managing asthma in accident and emergency departments: an assessment in non teaching hospitals

Background: The management and follow-up of asthma patients presenting at Accident and Emergency (A&E) departments have mostly been studied in children's hospitals or specialised teaching hospitals. Aims: To study the adequacy of assessment, treatment and follow-up of patients presenting at A&E departments in non-teaching hospitals. Methods: A twenty-five per cent sample of presentations to A&E departments in all public hospitals in the Illawarra for one year was selected for a case note audit. Information on demographics, assessment, management and referral was extracted from the A&E case notes and medical records of cases with documentation of a final diagnosis of asthma. Chi square and Fischer's Exact tests were used for comparisons among hospitals. Results: Of 359 presentations with a final diagnosis of asthma, 88% were self referred and only 5% were first presentations. Objective measures of airways obstruction was not documented in 34% of admissions and 48% of nonadmissions. There was no documented follow-up in 28% of cases. The assessment and management of asthma in A&E was significantly poorer in smaller hospitals. Conclusion: Evidence of high use of A&E as a primary care facility by asthma patients was found in the study. There is a need to implement protocols to optimise assessment and treatment of asthma in smaller hospitals. (Aust NZ J Med 1993; 23: 672–677.).     

急性脑血管病患者血清髓鞘碱性蛋白含量研究

用酶联免疫吸附法对３０例急性脑血管病（ＣＶＤ）患者及３２位正常人血清髓鞘碱性蛋白（ＭＢＰ）含量进行检测。结果表明：急性ＣＶＤ组患者血清ＭＢＰ含量显著高于正常人组（Ｐ＜０．０１）；血清ＭＢＰ含量与急性ＣＶＤ的严重程度相关。提示检测血清ＭＢＰ含量对急性ＣＶＤ诊断及预后判断有重要价值     

急性脑血管病肿瘤坏死因子-α的临床研究

目的：探讨肿瘤坏死因子-α（TNF-α）在急性脑血管病（ACVD）中的作用及其变化的临床意义。方法：选取95例ACVD患者，并设性别及年龄相匹配的血清对照组（20例）及脑脊液对照组（10例）。应用酶联免疫吸附法（ELISA）于发病后第1、3、7、14d测定血清和脑脊液中TNF-α。结果：①三种脑血管病患者血清TNF-α动态变化存在差异，脑出血和脑梗死组的峰值单间为发病后第3d，而蛛网膜下腔出血（SAH）组为第1d。②脑梗死患者血清TNF-α水平与梗死面积、神经功能缺损程度及病情恶化与否相关。③SAH组于发病后第1d、3d、7d脑脊液TNF-α值高于血清，14d时降至对照组水平并与血清无差异。结论：①脑梗死患者血清TNF-α的动态观察，可为临床预测梗死灶大小、神经功能缺损程度及病情恶化与否提供依据。②发病早期的脑梗死患者若CT未能显示病灶时，血清TNF-α的明显升高有助于临床诊断和治疗。③SAH患者脑脊液中TNF-α水平明显高于血清，进一步提示脑内神经组织可产生TNF-α。脑脊液中TNF-α的持续明显升高可能与SAH后脑血管痉挛有关。④TNF-α参与了ACVD的炎性反应过程，早期抑制TNF产生及抗炎性反应的治疗可能具有潜在的临床价值。     

血半胱氨酸蛋白酶抑制剂C水平对急性脑血管病患者早期肾损害的诊断价值

目的探讨急性脑血管病患者早期肾损害的机制及早期监测指标。方法对194例急性脑血管病患者(包括脑梗死129例,脑出血65例)及60例正常对照者同时测定血半胱氨酸蛋白酶抑制剂C(Cys-C)和血肌酐(SCr)浓度,对其中血Cys-c浓度增高但SCr浓度正常的48例急性脑血管病肾早期损害患者用甘露醇治疗,并检测治疗前后血Cys-c浓度。结果在早期肾损害组,血Cys-c浓度明显高于对照组(P<0.001),而SCr浓度2组无显著性差异(P>0.05)。48例急性脑血管病肾早期损害者经甘露醇治疗后,血Cys-c浓度较治疗前明显降低(P<0.001)。结论血清Cys-c测定有助于早期发现肾功能损害,治疗脑血管病的同时应注意监测肾功能。
