Real-World Populational-Based Quality of Life and Functional Status After Stroke.

OBJECTIVES: This study aimed to describe health-related quality of life (HRQoL) 3 months and 1 year after stroke, compare HRQoL between dependent (modified Rankin scale [mRS] 3-5) and independent (mRS 0-2) patients, and identify factors predictive of poor HRQoL. METHODS: Patients with a first ischemic stroke or intraparenchymal hemorrhage from the Joinville Stroke Registry were analyzed retrospectively. Using the 5-level version of the EuroQol-5D questionnaire, HRQoL was calculated for all patients 3 months and 1 year after stroke, stratified by mRS score (0-2 or 3-5). One-year HRQoL predictors were examined using univariate and multivariate analyses. RESULTS: Three months after a stroke, data from 884 patients were analyzed; 72.8% were categorized as mRS 0-2 and 27.2% as mRS 3-5, and the mean HRQoL was 0.670 ± 0.256. At 1-year follow-up, 705 patients were evaluated; 75% were classified as mRS 0-2 and 25% as mRS 3-5, and the mean HRQoL was 0.71 ± 0.249. An increase in HRQoL was observed between 3 months and 1 year (mean difference 0.024, P < .0001), both in patients with 3-month mRS 0-2 (0.013, P = .027) and mRS 3-5 (0.052, P < .0001). Increasing age, female sex, hypertension, diabetes, and a high mRS were associated with poor HRQoL at 1 year. CONCLUSIONS: This study described the HRQoL after a stroke in a Brazilian population. This analysis shows that the mRS was highly associated with HRQoL after stroke. Age, sex, diabetes, and hypertension were also associated with HRQoL, although not independently of mRS.

Ancient Observation of Spinal Cord Injury: The Case of the Assyrian Lion.

The description of paraplegia is considered a milestone in the history of neurology. The Egyptians provided excellent descriptions of spinal cord injuries, the Bible has several references to paraplegia, and, more recently, the pioneers of neurology described the classic syndromes related to spinal injuries and paraplegia. Here, we describe an ancient observation by the Assyrian people of paraplegia in an animal. In ancient Assyria, lion hunting was a ritualized activity conducted for political and religious purposes. The Lion Hunt of Ashurbanipal, a series of Assyrian palace reliefs from the North Palace at Nineveh dating from approximately 645 BCE, which is now in the British Museum in London, UK, shows King Ashurbanipal hunting lions. Applying modern knowledge of mammalian dermatomes to the images, we reveal a detailed and precise observation of paraplegia after spinal cord injury.

Stroke recurrence in the different subtypes of ischemic stroke. The importance of the intracranial disease.

The aim of the study was to analyze the long-term recurrence rate in patients with a first-ever ischemic stroke secondary to intracranial large artery atherosclerosis (LAA) in a Brazilian population. METHODS: All stroke patients admitted to the hospital between October 2012 and September 2015 were evaluated. The stroke mechanism subtypes were classified as cardioembolism, LAA, small-vessel occlusion, other determined etiologies, and stroke of undetermined etiology. RESULTS: The 359 first-ever ischemic stroke patients were followed up for a mean time of 21.6 ± 15.1 months. The LAA intracranial (38.9%) and extracranial (24.6%) stroke patients presented with a higher stroke recurrence. Intracranial LAA [HR, 10.2 (3.6-29.1); p < 0.001] and extracranial LAA [HR, 5.05 (1.79-14.2); p = 0.002] were the only conditions to show positive correlation with the recurrence rate, after adjusting for risk factors, thrombolysis, and National Institutes of Health Stroke Scale score at admission. CONCLUSION: Intracranial LAA presents a higher incidence of recurrence of ischemic stroke when compared with other etiologies in a Southern Brazilian population.

Dandy-Walker syndrome in adult mimicking myasthenia gravis.

The Dandy-Walker syndrome (DWS) is a rare posterior fossa malformation. The DWS can occur associated with other brain or systemic malformations, but ocular abnormalities in this disease are rare and clinical findings mimicking myasthenia gravis have not been described to date. We report a 23-year-old woman who presented mild limitation of the ocular movements with progressive palpebral ptosis, which changed in intensity during the day. The investigation showed negative anti-acetylcholine receptor antibody, repetitive nerve stimulation and "Tensilon test", but the brain magnetic resonance image reveals DWS with hydrocephalus associated with callosal dysgenesis. The characteristic of disease, clinical manifestations and pathologic features, specially the clinical evaluation of ocular abnormalities in suspicion of DWS, including the MG in differential diagnosis are discussed.

Key performance indicators for stroke from the Ministry of Health of Brazil: benchmarking and indicator parameters.

METHODS: All 16 KPIs were analyzed, including the percentage of patients admitted to the stroke unit, venous thromboembolism prophylaxis in the first 48 hours after admission, pneumonia and hospital mortality due to stroke, and hospital discharge on antithrombotic therapy in patients without cardioembolic mechanism. RESULTS: Both centers admitted over 80% of the patients in their stroke unit. The incidence of venous thromboembolism prophylaxis was > 85%, that of in-hospital pneumonia was < 13%, the hospital mortality for stroke was < 15%, and the hospital discharge on antithrombotic therapy was > 70%. CONCLUSION: Our results suggest using the parameters of all of the 16 KPIs required by the Ministry of Health of Brazil, and the present results for the two stroke units for future benchmarking.

Comparing the Comprehensive Stroke Ward Versus Mixed Rehabilitation Ward-The Importance of the Team in the Acute Stroke Care in a Case-Control Study.

BACKGROUND AND PURPOSE: Ischemic stroke is one of the most frequent causes of death in Brazil. Many measures have been taken to reduce this tragic outcome, and one of those is the implementation of stroke units in hospitals. The aim of the present study is to analyze the in-hospital complications for patients with ischemic stroke admitted in a comprehensive stroke ward (CSW) as compared to patients admitted in a mixed rehabilitation ward (MRW). METHODS: A retrospective interventional study with historic controls of patients admitted to the Neurology Division between January 2010 and October 2013. Patients admitted between January 2010 and September 2012 were included in the MRW group, and patients admitted from October 2012 until October 2013 were included in the CSW group. Throughout the whole study period, the same team assisted all the patients. Both groups were paired in relation to age and gender. The rate of in-hospital complications, mortality, and independency on discharge were evaluated in both groups. RESULTS: Each group was comprised of 91 patients. There were no statistically significant differences for any of the risk factors analyzed between the 2 groups nor for outcome measures-in-hospital complications, mortality, and independence on discharge. CONCLUSION: The present study demonstrated that in-hospital complications, independence on discharge, and mortality have similar rates in patients admitted to an MRW compared to patients admitted to a CSW, when the same staff provided them with specialized in-hospital care. EVIDENCE LEVEL: Case-control study-Evidence Level 3.

Bone marrow transplantation in patients with storage diseases: a developing country experience.

Bone marrow transplantation (BMT) is a therapeutic option for patients with genetic storage diseases. Between 1979 and 2002, eight patients, four females and four males (1 to 13 years old) were submitted to this procedure in our center. Six patients had mucopolysaccharidosis (MPS I in 3; MPS III in one and MPS VI in 2), one had adrenoleukodystrophy (ALD) and one had Gaucher disease. Five patients had related and three unrelated BMT donor. Three patients developed graft versus host disease (two MPS I and one MPS VI) and died between 37 and 151 days after transplantation. Five patients survived 4 to 16 years after transplantation. Three patients improved (one MPS I; one MPS VI and the Gaucher disease patient), one patient had no disease progression (ALD) and in one patient this procedure did not change the natural course of the disease (MPS III).

Sodium nitroprusside: low price and safe drug to control BP during thrombolysis in AIS.

This study analyzes the use of sodium nitroprusside (SN) as an option to reduce blood pressure (BP) below 180/105 mmHg during the management of acute ischemic stroke (AIS) in patients submitted to intravenous thrombolysis.Method The sample was composed by 60 patients who had AIS and were submitted to intravenous rtPA, split in two groups: half in the control group (CG) with BP < 180/105 mmHg and half in SN group with BP > 180/105 mmHg. Outcome variables were any hemorrhagic transformation (HT); the presence of symptomatic HT, National Institute of Health Stroke Scale (NIHSS) after 24 hours of treatment; the independence on discharge and death until three months after stroke onset.Results There were no statistical differences between both groups to any of the outcome variables analyzed.Conclusion The SN might be safe for BP control during thrombolysis to AIS.

The use of neurovascular ultrasound versus digital subtraction angiography in acute ischemic stroke.

UNLABELLED: Cervical and intracranial arterial evaluation is an important issue for acute ischemic stroke (IS). OBJECTIVE: Compare the use of the neurovascular ultrasound examination (NVUE) to digital subtraction angiography (DSA) in acute IS patients for diagnosing significant extracranial and intracranial arteriopathy. METHOD: Nonconsecutive patients with IS or transient ischemic attack admitted within 12 hours of the onset of symptoms were evaluated retrospectively. Standardized NVUE and DSA were done in all patients within the first 120 hours of hospital admission. RESULTS: Twenty-four patients were included in the study. Compared to DSA, the NVUE demonstrated 94.7% sensitivity and 100% specificity for identifying symptomatic extracranial and/or intracranial arteriopathy. CONCLUSION: The standardized NVUE technique demonstrated high sensitivity and specificity compared to DSA for diagnosing arterial abnormalities in acute IS patients.

Incidence and mortality of ischemic stroke subtypes in Joinville, Brazil: a population-based study.

AIMS: To measure the incidence and mortality rates of ischemic stroke (IS) subtypes in Joinville, Brazil. METHODS: All first-ever IS patients that occurred in Joinville from January 2005 to December 2006 were identified. The IS subtypes were classified by the TOAST criteria, and the patients were followed-up for one year after IS onset. RESULTS: The age-adjusted incidence per 100,000 inhabitants was 26 (17-39) for large-artery atherosclerosis (LAA), 17 (11-27) for cardioembolic (CE), 29 (20-41) for small vessel occlusion (SVO), 2 (0.6-7) for stroke of other determined etiology (OTH) and 30 (20-43) for stroke of undetermined etiology (UND). The 1-year mortality rate per 100,000 inhabitants was 5 (2-11) for LAA, 6 (3-13) for CE, 1 (0.1-6) for SVO, 0.2 (0-0.9) for OTH and 9 (4-17) for UND. CONCLUSION: In the population of Joinville, the incidences of IS subtypes were similar to those found in other populations. These findings highlight the importance of better detection and control of atherosclerotic risk factors.

Is point-of-care accurate for indicating thrombolysis in anticoagulated patients on oral anticoagulation treatments?

UNLABELLED: The use of oral anticoagulation treatment (OAT) in patients with an international normalized ratio (INR) higher than 1.7 is a contraindication to thrombolysis in acute ischemic stroke. The aim of the present study is to compare the use of point-of-care (POC) coagulometers to the standard coagulation analysis (SCA) procedure of the INR as a decision-making test for use with patients taking OAT. METHOD: Eighty patients on chronic OAT underwent a POC and an SCA during a regular outpatient evaluation. RESULTS: When comparing the abilities of the POC test and the SCA test to identify adequate levels for thrombolysis (≤1.7), the POC had a sensitivity of 96.6% (95%CI 88.4-99.1) and a specificity of 60.0% (95%CI 38.6-78). POC overestimated INR levels by 0.51 points compared to the SCA test. CONCLUSION: POC has a high sensitivity compared to the SCA test for the identification of patients within the cut-off point for thrombolysis.

Cognitive impairment and antiphospholipid syndrome: is paradoxical embolism the rule?

OBJECTIVE: Although cognitive decline (CD) is described in antiphospholipid syndrome (APS), its physiopathology is unknown. Paradoxical embolization (PE) is related to CD in Alzheimer disease. The objective of this study was to determine whether PE plays a role in CD in APS patients through a significant right-to-left shunt (sRLS). METHODS: A total of 27 patients diagnosed with APS without a history of stroke were tested for the presence of an sRLS using a contrast-enhanced transcranial Doppler (cTCD) ultrasound. Cognitive decline was assessed using the mini mental state examination (MMSE), the Montreal cognitive assessment (MoCA), and a battery of neuropsychological tests. RESULTS: Of the 27 patients, 19 (70%) had a non-sRLS condition (≤ 10 high-intensity transient signs [HITS] on cTCD), and 8 (30%) had an sRLS. Patients with more than 10 years of scholarship performed significantly better on both the MMSE (P = 0.048) and MoCA (P = 0.03). Individuals of the non-sRLS group with more than 10 years of scholarship had better performances on the five-point test (FPT) when compared with the sRLS group (P = 0.01). CONCLUSIONS: Patients without sRLS and with more years of education exhibited a better performance in cognitive tests than sRLS patients.

Brazilian guidelines for the application of transcranial ultrasound as a diagnostic test for the confirmation of brain death.

Neurosonological studies, specifically transcranial Doppler (TCD) and transcranial color-coded duplex (TCCD), have high level of specificity and sensitivity and they are used as complementary tests for the diagnosis of brain death (BD). A group of experts, from the Neurosonology Department of the Brazilian Academy of Neurology, created a task force to determine the criteria for the following aspects of diagnosing BD in Brazil: the reliability of TCD methodology; the reliability of TCCD methodology; neurosonology training and skills; the diagnosis of encephalic circulatory arrest; and exam documentation for BD. The results of this meeting are presented in the current paper.

Neurological diagnoses in the emergency room: differences between younger and older patients.

UNLABELLED: Neurological diseases are prevalent in the emergency room (ER). The aim of this study was to compare the neurological diagnoses between younger and older patients evaluated in the ER of a tertiary care hospital. METHOD: Patients admitted to the ER who required neurological evaluation in the first 24 hours were separated into two groups based on age, ≤50 years old and >50 years old. RESULTS: Cerebrovascular disease (59.6% vs. 21.8%, p<0.01) was most frequent in the >50 years old group. Seizures (8.1% vs. 18.6%, p<0.01) and primary headache (3.7% vs. 11.4%, p<0.01) were most frequent in the ≤50 years old group. CONCLUSION: The current study demonstrated that these three neurological diagnoses represented the majority of the neurological evaluations in the ER. National guidelines for ER teams that treat these prevalent disorders must be included in clinical practice and training.
