Thrombolysis (rTPA) and mechanical thrombectomy (MT) are cost-effective treatments for ischemic stroke. However, little is known about the impact of different types of health systems (HSs) on the outcome and cost of ischemic stroke.Literature search was performed on PubMed/OVID for studies without time limits. The year of publication, type of HS, cost of intervention treatment (rTPA/MT), cost of control strategy (conservative treatment or rTPA), quality-adjusted life years (QALYs) gained, and percentage of gross domestic product spent on health were recorded. The inclusion criteria were English literature, cost-effectiveness, and cost-utility analyses. The exclusion criterion was the absence of geographic coherence between the derived QALYs and the costs. The costs were inflated to 2021 and then converted to US dollar/euro. An analysis of variance or Kruskal-Wallis test was used to compare the percentage of cost reduction and the QALYs gained. Gross domestic product percentage was correlated with the QALYs gained.Thirty-five studies were analyzed. No significant differences in the percentage of cost reduction were found among the different types of HS (Beveridge -14.74% [95% confidence interval {CI} -57.94/53.08] vs. Bismarck -2.27% [95% CI -122.73/118.18] vs. national insurance -0.015% [95% CI -16.96/51.00] vs. private insurance -4.05% [95% CI -32.62/13.18]). No differences were found in QALYs gained among the different HS (Beveridge 1021 [95% CI -36.37/1705.04] vs. Bismarck 440 [95% CI -2290.68/3870.68] vs. national insurance 643 [95% CI -137.54/2366.21] vs. private insurance 550 [95% CI 131.54/1128.06]). No differences were found among the QALYs gained between rTPA/conservative treatment versus rTPA/MT and rtPA + MT/MT. The percentage of gross domestic product spent on health did not correlate with the QALYs gained (rho = -0.16; P = 0.56).MT and rTPA are independently cost-effective among different HS.

Introduction: Recent anticoagulant intake represents a contraindication for thrombolysis in acute ischemic stroke. Idarucizumab reverses the anticoagulant effect of dabigatran, potentially allowing for thrombolysis. This nation-wide observational cohort study, systematic review, and meta-analysis evaluated the efficacy and safety of thrombolysis preceded by dabigatran-reversal in people with acute ischemic stroke. Patients and methods: We recruited people undergoing thrombolysis following dabigatran-reversal at 17 stroke centers in Italy (reversal-group), people on dabigatran treated with thrombolysis without reversal (no-reversal group), and age, sex, hypertension, stroke severity, and reperfusion treatment-matched controls in 1:7 ratio (control-group). We compared groups for symptomatic intracranial hemorrhage (sICH, main outcome), any brain hemorrhage, good functional outcome (mRS 0–2 at 3 months), and death. The systematic review followed a predefined protocol (CRD42017060274), and odds ratio (OR) meta-analysis was implemented to compare groups. Results: Thirty-nine patients in dabigatran-reversal group and 300 matched controls were included. Reversal was associated with a non-significant increase in sICH (10.3% vs 6%, aOR = 1.32, 95% CI = 0.39–4.52), death (17.9% vs 10%, aOR = 0.77, 95% CI = 0.12–4.93) and good functional outcome (64.1% vs 52.8%, aOR = 1.41, 95% CI = 0.63–3.19). No hemorrhagic events or deaths were registered in no-reversal group (n = 12). Pooling data from 3 studies after systematic review (n = 1879), reversal carried a non-significant trend for sICH (OR = 1.53, 95% CI = 0.67–3.50), death (OR = 1.53, 95% CI = 0.73–3.24) and good functional outcome (OR = 2.46, 95% CI = 0.85–7.16). Discussion and conclusion: People treated with reperfusion strategies after dabigatran reversal with idarucizumab seem to have a marginal increase in the risk of sICH but comparable functional recovery to matched patients with stroke. Further studies are needed to define treatment cost-effectiveness and potential thresholds in plasma dabigatran concentration for reversal.

Objectives: To assess acute lipid profiles, atrial fibrillation and other cardiovascular risk factors in patients undergoing treatments by thrombectomy (EVT) with acute ischemic stroke (AIS). Methods: We performed a retrospective analysis of the lipid profile and vascular risk factor in 1639 consecutive patients with acute ischemic stroke between January 2016 and December 2021. To assess lipid profiles, laboratory tests, including total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglycerides (TG), were obtained the day after admission. We also examined assessed the association between lipid profile, AF and EVT in multivariate logistic regression analysis. Results: Median age of patients was 74 years, 54.9% were males (95% CI 52.5-57.4%), and 26.8% (95% CI, 24.7-29.0%) had AF. EVT patients (n= 370; 22.57 %; 95% CI, 20.6-24.7) showed no difference in age (median 73 years [IQR; 63-80 ] versus 74 years [ QR; 63-82+ HbA1c levels (median 5.8 [IQR; 5.4-6.2] versus 5.9 [ IQR; 5.4-6.4+TG/HDL ratio (median 2.40 [IQR; 1.65-3.48#43; versus[IQR; 1.73-3.64)] diabetes (OR 0.82; 95% CI 0.61 to 1.08), hypertension (OR 0.87; 95% CI 0.68 to 1.12) and obesity (OR 1.06; 95% CI 0.78 to 1.42) compared to non-EVT patients. Conversely, EVT patients showed lower levels of TC (160 mg/dl[ IQR;139-187] versus 173 mg/dl [ IQR;148-202] P Conclusion: Total cholesterol and all cholesterol-related measures were significantly lower in patients undergoing thrombectomy than in other stroke patients. Conversely, we found that AF was significantly high in patients with EVT, suggesting that hypercholesterolemia could be mainly linked to small-vessel occlusion stroke while large vessel occlusion (LVO) stroke could show different causes. AIS patients may have different pathogenesis and their understanding may improve enhance the discovery of specific and tailored preventive treatments.

PurposeThe purpose was to evaluate the numeric correlation between modified treatment in cerebral infarction (mTICI)≥2b/3 and modified Rankin Scale (mRS)≤2 in RCT and registries.Material and MethodsLiterature research was performed on Pubmed/OVID for studies in 2015-2021, mTICI, mRS and sample-size were recorded. Exclusion criteria were monocentric study, not-human and not-English. Studies qualities were assessed with MINORS/RoB2. Meta-analysis with random effect model was performed. Meta-logistic and meta-linear regressions were used to correlate mTICI and mRS in both RCTs and registries. Z-test was used for comparing coefficients between RCTs/registries.Results We evaluated thirty-four studies (17 registries; 17 RCTs) for 29540 patients (27031 from registries (median registry 1192.0 [CI95% 698.7-1992.8]; 2509 from RCTs [median RCT 165.0 [CI95% 98.1-234.0]). 10/17(58.8%) registries considered also vertebrobasilar system strokes. Overall mRs≤2 was 46.0 (CI95% 43.8-48.3) with I2=92.6%.The odd-ratio of obtaining a mRS≤2 for a singular increased of mTICI≥2b rate was: 1.49(CI95% 1.22-2.01) for all studies (for 1% increase of mTICI≥2b the odds for obtaining mRS≤2 was 1.49), 1.50(CI95% 1.00-2.23) for RCTs and 1.50(CI95% 1.10-2.23) for registries. mTICI≥2b and mRS had a positive correlation with coefficient of 0.49(CI95% 0.22-0.75, p=0.001) for all studies (for 1% increase of mTICI≥2b the mRS≤2 rate augment by 0.49%), 0.51(CI95% 0.10-0.91) for RCTs and 0.46(CI 95% 0.09-0.84) for registries.No differences were found in coefficients between RCTs/registries (p=0.50; p=0.57; respectively).ConclusionsUnitary increased of mTICI≥2b rate correspond to an augment of mRS≤2 by 0.49(CI95% 0.22-0.75) with odd-ratio of obtaining mRS≤2 of 1.49(CI95% 1.22-2.01), without significantly differences in coefficients.

Despite mounting evidence, there is uncertainty on the impact of the interplay between weather and pollution features on the risk of acute cerebrovascular events (CVE). We aimed at appraising role of weather and pollution on the daily risk of CVE.Anonymized data from a hub CVE center in a large metropolitan area were collected and analyzed according to weather (temperature, pressure, humidity, and rainfall) and pollution (carbon monoxide [CO], nitrogen dioxide [NO2], nitrogen oxides [NOX], ozone [O3], and particulate matter [PM]) on the same and the preceding days. Poisson regression and time series analyses were used to appraise the association between environmental features and daily CVE, distinguishing also several subtypes of events.We included a total of 2534 days, with 1363 days having ≥1 CVE, from 2012 to 2017. Average daily rate was 1.56 (95% confidence interval: 1.49; 1.63) for CVE, with other event rates ranging between 1.42 for stroke and 0.01 for ruptured intracranial aneurysm. Significant associations were found between CVE and temperature, pressure, CO, NO2, NOX, O3, and PM10 µm (all P0.05), whereas less stringent associations were found for humidity, rainfall, and PM2.5 µm. Time series analysis exploring lag suggested that associations were stronger at same-day analysis (lag 0), but even environmental features predating several days or weeks were significantly associated with events. Multivariable analysis suggested that CO (point estimate 1.362 [1.011; 1.836], P=0.042) and NO2 (1.011 [1.005; 1.016], P0.001) were the strongest independent predictors of CVE.Environmental features are significantly associated with CVE, even several days before the actual event. Levels of CO and NO2 can be potentially leveraged for population-level interventions to reduce the burden of CVE.

Despite mounting evidence, the impact of the interplay between weather and pollution features on the risk of acute cardiac and cerebrovascular events has not been entirely appraised. The aim of this study was to perform a comprehensive cluster analysis of weather and pollution features in a large metropolitan area, and their association with acute cardiac and cerebrovascular events.Anonymized data on acute myocardial infarction (AMI) and acute cerebrovascular events were obtained from 3 tertiary care centers from a single large metropolitan area. Weather and pollution data were obtained averaging measurements from several city measurement stations managed by the competent regional agency for enviromental protection, and from the Metereological Center of Italian Military Aviation. Unsupervised machine learning was performed with hierarchical clustering to identify specific days with distinct weather and pollution features. Clusters were then compared for rates of acute cardiac and cerebrovascular events with Poisson models.As expected, significant pairwise correlations were found between weather and pollution features. Building upon these correlations, hierarchical clustering, from a total of 1169 days, generated 4 separate clusters: mostly winter days with low temperatures and high ozone concentrations (cluster 1, N.=60, 5.1%), days with moderately high temperatures and low pollutants concentrations (cluster 2, N.=419, 35.8%), mostly summer and spring days with high temperatures and high ozone concentrations (cluster 3, N.=673, 57.6%), and mostly winter days with low temperatures and low ozone concentrations (cluster 4, N.=17, 1.5%). Overall cluster-wise comparisons showed significant differences in adverse cardiac and cerebrovascular events (P0.001), as well as in cerebrovascular events (P0.001) and strokes (P=0.001). Between-cluster comparisons showed that cluster 1 was associated with an increased risk of any event, cerebrovascular events, and strokes in comparison to cluster 2, cluster 3 and cluster 4 (all P0.05), as well as AMI in comparison to cluster 3 (P=0.047). In addition, cluster 2 was associated with a higher risk of strokes in comparison to cluster 4 (P=0.030). Analysis adjusting for season confirmed the increased risk of any event, cerebrovascular events and strokes for cluster 1 and cluster 2.Unsupervised machine learning can be leveraged to identify specific days with a unique clustering of adverse weather and pollution features which are associated with an increased risk of acute cardiovascular events, especially cerebrovascular events. These findings may improve collective and individual risk prediction and prevention.

A wide range of acute neurological disorders may present with symptoms similar to a stroke, so-called 'stroke mimics'. Migraine aura and seizures account for the most extensive stroke mimics population. A large number of patients with a definite stroke mimics diagnosis (most commonly those with psychiatric disorders or seizures) had been treated with IV alteplase without adverse related events. We report a case of a man aged 70 years admitted to the emergency room because of acute onset of delirium and a loss of strength in the left arm (National Institutes of Health Stroke Scale {NIHSS}: 10), severe hyponatremia (127 mEq/L), and no evidence of intracranial arterial occlusion at CT scan. He was eligible for intravenous thrombolysis and, after treatment, neurological symptoms improved (NIHSS: 2). The subsequent appearance of "clonus" in the left lower limb, the persistence of hyponatremia, and the presence of electroencephalogram (EEG) abnormalities led to the clinical suspicion of focal motor-onset seizure with impaired awareness. The patient was treated successfully with anti-seizure medications (ASMs): lacosamide 200 mg IV during the acute setting care, followed by oral lacosamide 200 mg bis in die (BID). Since two other focal seizures occurred, brivaracetam 25 mg BID has been added in therapy with subsequent clinical discontinuance and EEG normalization. Two consecutive magnetic resonance imaging (MRI) examinations showed several cortical lesions restricted in high signal in diffusion-weighted imaging (DWI) which corresponding to T2-weighted and fluid-attenuated inversion recovery (FLAIR) hyperintensities, but without lesions evidence in apparent diffusion coefficient (ADC) map. These radiological changes disappeared at a follow-up MRI performed 20 days after the symptoms' onset. The patient fully recovered was discharged home without developing pharmacological adverse events. In this case, MRI provided an opportunity for early identification of seizure-related alterations. Hence, we discuss how prospective MRI studies during seizures and interictal period would contribute to defining the relationship between the electroclinical characteristics and MRI alteration patterns, and therefore, the potential role of MRI in the differential diagnosis between seizures and stroke mimic.

Introduction: Increasing evidence supports the relationship between vitamin D and stroke. Vitamin D has now been proposed as a prognostic biomarker also for functional outcome in stroke patients. Methods: A revision of the data suggests that low vitamin D is associated more with ischemic than with haemorrhagic stroke, even if the role of optimal vitamin D levels for vascular wall is still unclear. Vitamin D deficiency induces with different mechanisms an alteration of vascular wall. Results: However, to date, the research supporting the effectiveness of vitamin D supplementation in stroke and in post-stroke recovery is still inadequate and conclusive evidences have not been published. Conclusion: In this review, we provide a better understanding of the role of vitamin D in stroke.

Introduction To describe clinical, neuroimaging, and laboratory features of a large cohort of Italian patients with reversible cerebral vasoconstriction syndrome. Methods In the setting of the multicenter Italian Project on Stroke at Young Age (IPSYS), we retrospectively enrolled patients with a diagnosis of definite reversible cerebral vasoconstriction syndrome according to the International Classification of Headache Disorders (ICHD)-3 beta criteria (6.7.3 Headache attributed to reversible cerebral vasoconstriction syndrome, imaging-proven). Clinical manifestations, neuroimaging, treatment, and clinical outcomes were evaluated in all patients. Characteristics of reversible cerebral vasoconstriction syndrome without typical causes (“idiopathic reversible cerebral vasoconstriction syndrome”) were compared with those of reversible cerebral vasoconstriction syndrome related to putative causative factors (“secondary reversible cerebral vasoconstriction syndrome”). Results A total of 102 patients (mean age, 47.2 ± 13.9 years; females, 85 [83.3%]) qualified for the analysis. Thunderclap headache at presentation was reported in 69 (67.6%) patients, and it typically recurred in 42 (60.9%). Compared to reversible cerebral vasoconstriction syndrome cases related to putative etiologic conditions (n = 21 [20.6%]), patients with idiopathic reversible cerebral vasoconstriction syndrome (n = 81 [79.4%]) were significantly older (49.2 ± 13.9 vs. 39.5 ± 11.4 years), had more frequently typical thunderclap headache (77.8% vs. 28.6%) and less frequently neurological complications (epileptic seizures, 11.1% vs. 38.1%; cerebral infarction, 6.1% vs. 33.3%), as well as concomitant reversible brain edema (25.9% vs. 47.6%). Conclusions Clinical manifestations and putative etiologies of reversible cerebral vasoconstriction syndrome in our series are slightly different from those observed in previous cohorts. This variability might be partly related to the coexistence of precipitating conditions with a putative etiologic role on disease occurrence.

The association between atrial fibrillation (AF), acute coronary syndrome (ACS), and stroke is a complex scenario in which the assessment of both thrombotic and hemorrhagic risk is necessary for scheduling an individually tailored therapeutic plan. Recent clinical trials investigating new antithrombotic drugs and dual and triple pathways in high-risk cardiovascular patients have revealed a new therapeutic scenario. In this paper, we review the burden of ischemic stroke (IS) in patients post-myocardial infarction with and without atrial fibrillation and the possible therapeutic strategies from a stroke point of view.

Stroke is the leading cause of disability and mortality worldwide. After an acute cerebrovascular ischemia, recurrent vascular events, including recurrent stroke or transient ischemic accidents (TIA), occur in around 20% of cases within the first 3 months. In order to minimize this percentage, antiplatelet therapy may play a key role in the management of non-cardioembolic cerebrovascular events. This review will focus on the current evidence of antiplatelet therapies most commonly discussed in practice guidelines and used in clinical practice for the treatment of stroke/TIA complications. The antiplatelet therapies most commonly used and discussed are as follows: aspirin, clopidogrel, and ticagrelor.

Background: The major endovascular mechanic thrombectomy (MT) techniques are: Stent-Retriever (SR), aspiration first pass technique (ADAPT) and Solumbra (Aspiration + SR), which are interchangeable (defined as switching strategy (SS)). The purpose of this study is to report the added value of switching from ADAPT to Solumbra in unsuccessful revascularization stroke patients. Methods: This is a retrospective, single center, pragmatic, cohort study. From December 2017 to November 2019, 935 consecutive patients were admitted to the Stroke Unit and 176/935 (18.8%) were eligible for MT. In 135/176 (76.7%) patients, ADAPT was used as the first-line strategy. SS was defined as the difference between first technique adopted and the final technique. Revascularization was evaluated with modified Thrombolysis In Cerebral Infarction (TICI) with success defined as mTICI ≥ 2b. Procedural time (PT) and time to reperfusion (TTR) were recorded. Results: Stroke involved: Anterior circulation in 121/135 (89.6%) patients and posterior circulation in 14/135 (10.4%) patients. ADAPT was the most common first-line technique vs. both SR and Solumbra (135/176 (76.7%) vs. 10/176 (5.7%) vs. 31/176 (17.6%), respectively). In 28/135 (20.7%) patients, the mTICI was ≤ 2a requiring switch to Solumbra. The vessel’s diameter positively predicted SS result (Odd Ratio [OR] 1.12, Confidence of Interval [CI] 95% 1.03–1.22, p = 0.006). The mean number of passes before SS was 2.0 ± 1.2. ADAPT to Solumbra improved successful revascularization by 13.3% (107/135 (79.3%) vs. 125/135 (92.6%)). PT was superior for SS comparing with ADAPT (71.1 min (CI 95% 53.2–109.0) vs. 40.0 min (CI 95% 35.0–45.2), p = 0.0004), although, TTR was similar (324.1 min (CI 95% 311.4–387.0) vs. 311.4 min (CI 95% 285.5–338.7), p = 0.23). Conclusion: Successful revascularization was improved by 13.3% after switching form ADAPT to Solumbra (final mTICI ≥ 2b was 92.6%). Vessel’s diameter positively predicted recourse to SS.

The goal of this study is to understand how very elderly patients (VEP) after ischemic stroke are currently treated in a Stroke Unit (SU) Hub in Italy. We designed a retrospective monocentric study on patients admitted in the SU of "AO San Camillo Forlanini" over an 8-year period.Data were collected among patients with acute ischemic stroke admitted to SU between January 2012 and December 2019. Patients were divided into three sub-groups: Adults (18-65 years); Elderly (66-85 years); and VEP (85 years). Vascular risk factors and clinical variables as predictors of short-term clinical outcome were compared among age groups.A total of 1979 patients were enrolled, 254 were VEP (12.8%). The proportion of VEP showed no significant modifications during the 8-year period (11.9% in 2012-2015 and 13.7% in 2016-2019; p=0.93). The proportion of women, hypertension and atrial fibrillation was significantly higher in VEP compared to other age groups (p0.001). The rate of VEP being treated with rt-PA increased from 2012-2015 to 2016-2019 (from 12.8% to 25.5%, p0.001). Endovascular thrombectomy was rarely performed in VEP (1.5% of VEP). Rt-PA treatment was associated with favorable outcome for all three age groups (p0.05).We showed that VEP present different vascular risk factor profiles, clinical features, and prognostic elements for short-term stroke outcome. Future studies will reveal whether we will observe an increasing trend in the use of rt-PA and endovascular thrombectomy and whether it will result in improved functional outcome for VEP.

Takayasu's arteritis (TA) is a chronic progressive vasculitis affecting large and medium-sized vessels, mainly in young subjects. It is most common in women with a higher prevalence in the Asian population. Stroke is a rare complication of TA, and these patients usually have a poor therapeutic response to revascularization treatments (thrombolysis and/or thrombectomy). We report a case of a male patient aged between 40 and 50 years admitted to our Emergency Department's Stroke Unit for sudden left hemiplegia, hypoesthesia, and dysarthria caused by right internal carotid artery (ICA), middle cerebral artery (MCA), and anterior cerebral artery (ACA) occlusion. He was treated with intravenous thrombolysis (r-tPA), endovascular carotid stenting, and thromboaspiration. We also revealed subclavian stenosis, vascular bruit, erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) elevation; therefore, a diagnosis of TA was made. Double antiplatelet therapy (DAPT) was started. Despite the early post-procedural carotid stent occlusion, the patient was discharged with a full recovery (neurological index of stroke scale [NIHSS] = 0). Thefive5-year clinical follow-up showed no clinical neurological relapses, and no arterial restenosis was found by further carotid artery echo-Doppler. Takayasu arteritis is a rare cause of ischemic stroke in young adults; however, stroke may be the first manifestation of the disease. Guidelines concerning the role of revascularization treatment in this type of patients are unclear. In this regard, the clinical experience and the multidisciplinary approach applied in our case had a pivotal role. Such an approach would eventually advocate for standardized treatment in patients with stroke and TA.

Background and aim of the work: We present a case of a woman affected by nonconvulsive status epilepticus (NCSE) caused by cerebral hyperperfusion syndrome (CHS) after carotid endarterectomy (CEA) who was successfully treated with Brivaracetam (BRV) administered via nasogastric tube (NGT). Case Presentation: An 82-years old woman was referred for increasing blood pressure, severe headache and two focal motor seizures on postoperative day four after right CEA. CT scan showed edema of the right hemisphere with a midline shift of 5 mm. The patient underwent daily Electroencephalography (EEG) monitoring which showed continuous epileptiform discharges over the right hemisphere, compatible with a diagnosis of status epilepticus. She was treated with standard antiepileptic drugs (Phenytoin, Lacosamide and Levetiracetam iv) without clinical response. A therapeutic trial with BRV 200mg administered via nasogastric tube (NGT) was tried which resulted in substantial clinical benefit. Conclusions: The administration of new antiepileptic drugs (AEDs) such as BRV may result in significant clinical improvement in refractory cases of status epilepticus. The enteral administration of AEDs via NGT should always be considered for refractory cases of status epilepticus when standard iv treatment has failed or is not possible.

Supplemental Digital Content is available in the text., Background and Purpose: We aimed to investigate the rate of hospital admissions for cerebrovascular events and of revascularization treatments for acute ischemic stroke in Italy during the coronavirus disease 2019 (COVID-19) outbreak. Methods: The Italian Stroke Organization performed a multicenter study involving 93 Italian Stroke Units. We collected information on hospital admissions for cerebrovascular events from March 1 to March 31, 2020 (study period), and from March 1 to March 31, 2019 (control period). Results: Ischemic strokes decreased from 2399 in 2019 to 1810 in 2020, with a corresponding hospitalization rate ratio (RR) of 0.75 ([95% CI, 0.71–0.80] P

In hospitals without stroke unit Department, the patients with acute ischemic stroke are stabilized in First Aid and sent to the Department of Internal Medicine. During the hospedalization period the patients undergo medical therapy for the stabilization of hemodynamic parameters and instrumental examinations for the determination of cardiovascular risk and thromboembolic evaluation. All patients are subjected to multidimensional evaluation of cognitive, praxis capacities, spatial-temporal orientation, quality of life and adherence to medical therapy. The aim of this study is evaluate the effect of Rotigotine patch on the impairment of neuro-cognitive capacity throught a continuous dopaminergic stimulation with transdermal administration. We have observed 19 patients (10 male and 9 female with range age 75-92 yrs) with Acute Ischemic Stroke stabilized in First Aid Depatment. The outcomes were the neurological changes from the baseline to 7 days in the clinical summury score on MMSE (on a scale from 0 to 30, with higher scores indicating fewer symtoms and lower physical limitations), Morinsky scale (on scale from 0 to 8, indicating adherence to therapy) and swallowing test (acts/minute). During the first week the patients were undergone to treatment with rotigotine 2 mg/24 hours. At the end of the treatment we obtained a statistically significant correlation about improvement of MMSE, Morinsky scale and swallowing test from a basal value. Rotigotine transdermal patches could be a new useful approach in the treatment of elderly hospetalized patients with acute ischaemic stroke correlated with cognitive impairment. Data shown that low dose of rotigotine patch could improves cognitive and praxis functions and therefore the quality of life of the hospitalized elderly patients. Rotigotine was effective and well-tolerated when used in routine clinical practice. Our data gave comfortable results but further evaluation are needed to have conclusive results.

Background Since its approval, the use of alteplase had been limited to patients aged ≤80 years. Aims TESPI trial had been designed to evaluate whether alteplase treatment within 3 h in patients with acute ischemic stroke aged >80 years resulted in favorable benefit/risk ratio compared with standard care. The meta-analysis of randomized controlled trials was updated to put findings in the context of all available evidence. Methods TESPI was a multicenter, open-label with blinded outcome evaluation, randomized, controlled trial. Main clinical endpoints were 90-day favorable functional outcome (mRS score 0–2) and mortality and symptomatic intracerebral hemorrhage. The trial was prematurely terminated for ethical reasons after publication of IST-3 trial which provided evidence of treatment benefit in elderly. Results Of the planned 600 patients, 191 (88 assigned to alteplase) were enrolled. Overall, 24/83 (28.9%) alteplase patients had a favorable outcome compared to 22/95 (23.2%) controls (non-significant absolute difference of 5.7% for alteplase; OR 1.35, 95% CI 0.69–2.64, P = 0.381). Rates of death were non-significantly lower in the alteplase patients (18.1% vs. 26.5%); rates of symptomatic intracerebral hemorrhage were similar between the two groups (5.9% vs. 5.1%). The updated meta-analysis showed consistent results with prior estimates and add weights. Conclusions The effects of alteplase observed in this interrupted trial did not reach statistical significance, probably for the small numbers, but are consistent with and add weight to the sum total of the randomized evidence demonstrating that alteplase is beneficial in patients with acute ischemic stroke aged over 80 years, particularly if given within 3 h.

Previous clinical studies suggest that intravenous (IV) recombinant tissue plasminogen activator (rt-PA) benefits stroke patients regardless of the underlying etiology. In this study, we assessed the possible differences in response to IV rt-PA between cardioembolic stroke and other stroke subtypes. A total of 303 consecutive stroke ischemic patients (from January 2005 to April 2014) admitted to our Stroke Unit and treated with IV rt-PA were retrospectively reviewed. All patients were classified in two groups: Cardioembolic (CE) and Non-Cardioembolic (NCE). We analyzed a total of 303 patients. Thirty patients died in the first hours after fibrinolysis and no statistically significant differences were found in two groups (14 CE vs 18 N-CE). We observed a significant differences in clinical outcome in terms of symptoms "improvement" (p< 0.01 .2) and symptoms" regression" (p

TIA has been recently re-defined as “a transient episode of neurological dysfunction caused by ischemia without acute infarction.” The gold standard to exclude the presence of ischemic lesions is acute brain MR. However, in many clinical settings, the 24/7 availability of MR is, at best, irregular. Being so, an appropriate adoption of this definition, which excludes the presence of ischemic lesions, can only be equally irregular. Our aim was to retrospectively compare the long-term outcomes of patients receiving acute care for TIA diagnosed with the new, tissue-based definition, and those diagnosed only on symptom duration. We analyzed 480 patients (227 males) from two centers: group 1 consisted of 162 patients with time-defined TIA; group 2 of 315 patients with negative brain DW-MRI (tissue-based TIAs). We considered the combined recurrence of TIA, stroke, myocardial infarction, and angina as endpoints. Both groups had a similar mean follow-up duration (38.3 months vs. 37.2 months) and were comparable for vascular risk factors, clinical features, and etiology. The combined endpoint rates were 11.1% for both groups, and the rates for segregate endpoints did not differ between groups. Recurrence was correlated with atrial fibrillation, diabetes, and high diastolic blood pressure. The long-term outcomes of TIA patients did not differ according to the definitions applied. Therein suggesting that, even without acute MRI results, a clinical diagnosis seemed to be enough to assure prompt medical treatment and similar long-term outcomes.

Background After a transient ischemic attack (TIA) or minor stroke, the long-term risk of stroke and other vascular events is not well known. In this follow-up to a report on 1-year outcomes from a registry of TIA clinics in 21 countries that enrolled 4789 patients with a TIA or minor ischemic stroke from 2009 through 2011, we examined the 5-year risk of stroke and vascular events. Methods We evaluated patients who had had a TIA or minor stroke within 7 days before enrollment in the registry. Among 61 sites that participated in the 1-year outcome study, we selected 42 sites that had follow-up data on more than 50% of their enrolled patients at 5 years. The primary outcome was a composite of stroke, acute coronary syndrome, or death from cardiovascular causes (whichever occurred first), with an emphasis on events that occurred in the second through fifth years. In calculating the cumulative incidence of the primary outcome and secondary outcomes (except death from any cause), we treated death as a competing risk. Results A total of 3847 patients were included in the 5-year follow-up study; the median percentage of patients with 5-year follow-up data per center was 92.3% (interquartile range, 83.4 to 97.8). The composite primary outcome occurred in 469 patients (estimated cumulative rate, 12.9%; 95% confidence interval [CI], 11.8 to 14.1), with 235 events (50.1%) occurring in the second through fifth years. At 5 years, strokes had occurred in 345 patients (estimated cumulative rate, 9.5%; 95% CI, 8.5 to 10.5), with 149 of these patients (43.2%) having had a stroke during the second through fifth years. Rates of death from any cause, death from cardiovascular causes, intracranial hemorrhage, and major bleeding were 10.6%, 2.7%, 1.1%, and 1.5%, respectively, at 5 years. In multivariable analyses, ipsilateral large-artery atherosclerosis, cardioembolism, and a baseline ABCD2 score for the risk of stroke (range, 0 to 7, with higher scores indicating greater risk) of 4 or more were each associated with an increased risk of subsequent stroke. Conclusions In a follow-up to a 1-year study involving patients who had a TIA or minor stroke, the rate of cardiovascular events including stroke in a selected cohort was 6.4% in the first year and 6.4% in the second through fifth years.

Stroke etiology in young adults and older patient differs considerably, as well as epidemiology and clinical features vary according to geographical criteria. To improve clinical management and optimize diagnostic work-up of young adults with acute cerebrovascular events, we analyzed retrospectively data of 6-year stroke unit case series. In this hospital case series study, we enrolled 145 patients with acute cerebrovascular events aged 16 to 49, consecutively admitted to a Community Hospital Hub Stroke Unit. We studied risk factors for stroke, the distribution of acute cerebrovascular events, stroke subtype, length of stay and clinical outcome: 70% of patients were admitted for acute ischemic event (45 female-F, 57 male-M), 10.5% intracranial hemorrhages (5F, 10M), 2.7% subarachnoid hemorrhage (2F, 2M), 2% venous sinus thrombosis (3F), 14.5 for acute ischemic attack (12F, 9M). Among ischemic stroke patients, the etiology was as follows: atherothrombosis 29.4%, cardioembolism 19.6%, arterial dissection 13.7%, other determined causes 8.8%, lacunar stroke 5.8%, and undetermined causes 22.54%. 15% of ischemic young patients were treated with r-TPA. The majority of patients returned home at discharge, whereas 30% needed intensive rehabilitation programme to regain independence in the activity of daily living. Dedicated health care programme targeting prevention and optimizing treatment of acute cerebrovascular events in young adults are desirable to improve prognosis among this socioeconomically active age group.

Charles Bonnet Syndrome (CBS) is a disorder with visual deficit and complex recurrent visual hallucination in conscious patients, described for the first time by Charles Bonnet. It has been found in association with variable pathologic conditions of the eyes, central visual pathways and occipital lobe. Occipital lobe lesion is an important cause of visual field deficit associated with elementary simple hallucinations, whereas complex hallucinations are related to occipitotemporal and occipitoparietal visual association neocortex damage.

To date dopaminergic therapy has shown unsatisfactory effect on vascular Parkinsonism symptoms and related disturbances. In this case series we describe the effect of rotigotine treatment in patients with subacute onset of Parkinson’s like movement (3-6 months) after ischemic stroke of thalamus or internal capsule areas with concomitant leukoencephalopathy. Rotigotine treatment seems to improve both motor and cognitive symptoms of our sample; further studies are needed to clarify the effect of continuous dopaminergic stimulation on nigro-striatal functions in vascular patients with Parkinsonism like disturbances.

Background: Pulmonary arteriovenous malformation (PAVM) is an abnormal communication between pulmonary arteries and veins responsible for right-to-left shunting that could induce the development of embolic stroke. Summary: We describe an 82-year-old woman without history of respiratory or neurological diseases, who presented at our observation unit with acute onset of cerebral ischemia. Clinical, laboratory and radiological findings diagnosed a PAVM. Key Messages: Usually, endovascular procedures based on embolization or, alternatively, surgery represent the recommended treatment. However, both hormonal therapy and thrombolytic therapy can be used. In our patient, treatment with warfarin induced a remission of symptoms. This strategy should be tested in larger studies. i 2014 S. Karger AG, Basel

Stroke is an acute condition characterized by a sudden decrease in blood flow to brain tissue, resulting in immediate deprivation of both glucose and oxygen. Different mechanisms are involved in the pathogenesis of stroke, but increasing evidence suggests that one of the processes worsening clinical outcome is inflammation with the synthesis and the release of pro-inflammatory cytokines that activate several cells contributing to the progression of brain injury. Monoclonal antibody therapy has proved useful and safe for the treatment of several systemic diseases. In contrast, the evidence is limited for the treatment of stroke. More studies are needed in order to standardize the method of treatment and establish if it is safe and effective.

Background Acute ischemic lesions on diffusion-weighted magnetic resonance imaging (DWI-MRI) are reliable predictors of recurrent stroke at 90 days. However, to date, limited information on transient ischemic attack (TIA) patients with positive DWI lesions for stroke risk from 1 to 5 years is available. In this study, we evaluated the role of positive DWI lesions and vascular risk factors on stroke, cardiovascular death, and mortality at 90 days (T0), 1 year (T1), and 5 years (T2). Moreover, we also evaluated the association between stroke risk and the presence of DWI lesions. Methods We performed an observational study on consecutive patients admitted to the emergency department of San Camillo-Forlanini Hospital, Rome, Italy, from January 2007 to November 2012. Over the study period, 4300 patients with TIA or ischemic stroke were examined by stroke specialists in an emergency room setting within 1 hour from admittance. Results In 510 of 4300 patients (11.86%), a TIA was diagnosed, and 445 patients satisfy the study inclusion criteria. For all 445 patients, the mean ABCD2 score was 4.35 ± 1.30. Using DWI-MRI, we identified acute ischemic lesions in 185 patients (41.57%). We did not observe any correlation between duration of symptoms, ABCD2 score, and positive or negative DWI lesions. Positivity for DWI was not associated with the presence of diabetes mellitus, hypertension, smoking habit, or age; however, an association with weakness was observed. We documented a time-dependent increase in the absolute risk of stroke: T0: 1.35% (95% confidence interval [CI], .81-2.8); T1: 4.78% (95% CI, 2.88-7.47); T2: 9.02% (95% CI, 4.66-5.70). We did not record any difference in stroke risk in patients with positive DWI lesions: T0: hazard ratio [HR], 1.43; 95% CI, .35-5.88; log-rank P = .60; T1: HR, 1.04; 95%CI, .42-2.61; log-rank P = .91; T2: HR, .83; 95% CI, .25-2.67; log-rank P = .86. Conclusions This long-term follow-up study in TIA patients documents that both positive and negative DWI patients treated with fast-track had similar long-term risks of stroke.

Neuroleptic Malignant-Like Syndrome (NMLS) is a rare, but potentially fatal complication of dopaminergic therapy in Parkinson's disease due to a sudden withdrawal of dopaminergic therapy. Here, we describe the case of a 79 years old woman, with 19 years history of Parkinson disease treated with L-dopa, dopamine agonists and MAO inhibitors, whose sudden withdrawal due to lack of therapeutic compliance, led to sudden onset of high fever, muscle rigidity, akinesia, autonomic dysfunction, impaired level of consciousness, respiratory distress and dysphagia with inability to take oral dopaminergic therapy. High blood levels of CPK and myoglobinaemia were found. The patient was treated with transdermal Rotigotine starting from a dose of 2 mg/24 hours, that was rapidly increased to 6 mg/24 hours, leading to resolution of the acute disturbances.

The use of telemedicine, especially as it is relates to telestroke, has significantly expanded over the past one or two decades. The fact that stroke therapy is a time-critical disease process, coupled with the relative paucity of stroke-trained practitioners, makes telestroke an attractive technique of care. The authors’ objective was to summarize the evidence that support the reliability of telemedicine for diagnosis and efficacy in acute stroke treatment in collaboration between hospitals in two different countries.

BACKGROUND AND PURPOSE: Sex related differences in cardiovascular disease and stroke are issues of increasing interest. The aim of this study was to evaluate for sex differences in clinical presentation, severity of stroke and outcome in a population of patients admitted to 4 public and 1 private hospitals in three different regions of Italy. METHODS: All hospital admissions for ischemic and haemorrhagic stroke (ICD-IX code 434 and 431 respectively) between January 1st and December 31st, 2011 at five different hospitals located in three different regions of Italy: Milan (North), Rome and Perugia (Center), and Palermo (South) have been recorded and sex-differences have been evaluated. RESULTS: A total of 1272 stroke patients were included in the analysis: 1152 ischemic and 120 haemorrhagic strokes, 567 women and 705 men. Compared to men, women were significantly older (mean age 75.2 SD 13.7 vs 71.5 SD 12.5 years, P

Muscle, peripheral nerve and autonomic disorders associated with acute cerebrovascular events are a large spectrum of conditions, their pathophysiology, clinical features, frequencies of occurrence, prognosis and treatment are diverse; the disturbances may be primary or secondary to acute cerebrovascular events. These disorders have been previously defined as multiple neurological complications as the underlying pathophysiological mechanism may largely differ; their characterization may need a full clinical, neuroradiological, neurophysiological, immunological, biochemical and genetic analyses assessment, and an autonomic function test may also be needed as well as nerve and muscle biopsy. In this chapter we present multiple neurological complications secondary to acute cerbrovascular events.

Mediterranean Cypress pollen is the major aerospore component in winter and early spring. Several recent studies have assessed the incidence of respiratory allergy to this pollen. A personal series of patients encountered in 1994-96 revealed a 9.33% incidence of positive prick-test responses to Cypress pollen among a population with atopical status. That series included 16 (19.05%) single and 68 (80.95%) multiple allergy sufferers. Among the former the symptoms encountered were rhinitis (62.5%) and asthma (37.5%). Given the ever-increasing incidence of Cypress pollen allergy, there is a need to restrict the planting of the tree for ornamental purposes, especially in areas with a high pollen count.

We have revisited 348 records of allergic outpatients to Parietaria, ratio M/F 1:1 and mean age 29.46 +/- 12.49 yrs. 97 of them were skin positive to Parietaria only (A-group: M/F 37/60); 251 patients were skin positive also to other allergens (B-group: M/F 137/114). Mean age of A-group patients (35.41 +/- 12.91) was higher than B-group (27.16 +/- 11.54; p001). Dividing mono and polysensitized subjects by age decade, a different distribution was found between the two groups (p001): monosensitized patients showed an increasing number of subjects from the 3rd to the 4th decade and a decreasing trend in the following decades; polysensitized patients showed a prevalence in age20 yrs and a decreasing trend in the other decades. In B-group Gramineae were the most frequent allergens associated to Parietaria (84.8%) followed by Olea Europaea (41.1%), Dermatophagoides farinae (37.4%) and Dermatophagoides pteronyssinus (36.2%). Main symptoms were rhinoconjunctivitis (187 cases), rhinitis + asthma (141 cases) and bronchial asthma (20 cases). Comparing the clinical features of the two groups, we have found that monosensitized patients showed a female prevalence, a prevalence of rhinitis with late onset of symptoms while in patients suffering from isolated asthma the onset was early.
