Abstract
BACKGROUND AND OBJECTIVE We aimed to evaluate the safety and outcomes of thrombectomy in anterior circulation acute ischaemic stroke recorded in the SITS-International Stroke Thrombectomy Register (SITS-ISTR) and compare them with pooled randomized controlled trials (RCTs) and two national registry studies. METHODS We identified centres recording ≥10 consecutive patients in the SITS-ISTR with at least 70% of available modified Rankin Scale (mRS) at 3 months during 2014-2019. We defined large artery occlusion as intracranial internal carotid artery, first and second segment of middle cerebral artery and first segment of anterior cerebral artery. Outcome measures were functional independence (mRS score 0-2) and death at 3 months and symptomatic intracranial haemorrhage (SICH) per modified SITS-MOST. RESULTS Results are presented in the following order: SITS-ISTR, RCTs, MR CLEAN Registry and German Stroke Registry (GSR). Median age was 73, 68, 71 and 75 years; baseline NIHSS score was 16, 17, 16 and 15; prior intravenous thrombolysis was 62%, 83%, 78% and 56%; onset to reperfusion time was 289, 285, 267 and 249 min; successful recanalization (mTICI score 2b or 3) was 86%, 71%, 59% and 83%; functional independence at 3 months was 45.5% (95% CI: 44-47), 46.0% (42-50), 38% (35-41) and 37% (35-41), respectively; death was 19.2% (19-21), 15.3% (12.7-18.4), 29.2% (27-32) and 28.6% (27-31); and SICH was 3.6% (3-4), 4.4% (3.0-6.4), 5.8% (4.7-7.1) and not available. CONCLUSION Thrombectomy in routine clinical use registered in the SITS-ISTR showed safety and outcomes comparable to RCTs, and better functional outcomes and lower mortality than previous national registry studies.

Abstract
Purpose: Transcranial B-mode sonography (TCS) of brain parenchyma is increasingly used as a diagnostic tool for movement disorders. Accordingly, experimental B-Mode Assist software was developed to enable digitized analysis of the echogenicity of predefined brain regions. The aim of the study was to assess the reproducibility of digitized TCS image analysis of the insula. Materials and Methods: A total of 130 patients with an indication for neurosonological examination were screened for participation in the study. The insula was imaged from the right temporal bone window using Virtual Navigator and TCS-MRI (magnetic resonance imaging) fusion imaging. All subjects were examined three times by two experienced sonographers. Corresponding images of the insula in the axial thalamic plane were encoded and digitally analyzed. Interclass correlation coefficient (ICC) and Spearman's rank correlation coefficient were used for the assessment of intra- and inter-reader as well as intra- and inter-investigator reliabilities. Results: TCS images of 114 patients were evaluated (21 patients with TIA, 53 patients with headache, 18 patients with essential tremor, 22 patients with neurodegerative disease). 16 patients were excluded from analysis due to insufficient bone window. The intra-reader, inter-reader, intra-investigator and inter-investigator ICCs/Spearman's rank correlation coefficients were 0.995/0.993, 0.937/0.921, 0.969/0.961 and 0.875/0.858, resp. Conclusion: The present study demonstrates a high reliability to reproduce echogenicity values of the insula using digitized image analysis and TCS-MRI fusion images with almost perfect intra-reader, inter-reader, intra-investigator and inter-investigator agreement.

Abstract
In this study different bacterial inoculation methods were tested for tobacco plants growing in a mine-soil contaminated with Pb, Zn, and Cd. The inoculation methods evaluated were: seed inoculation, soil inoculation, dual soil inoculation event, and seed+soil inoculation. Each inoculum was added at two bacterial densities (10(6) CFUs mL(-1) and 10(8) CFUs mL(-1)). The objectives were to evaluate whether or not the mode of inoculation or the number of applied microorganisms influences plant response. The most pronounced bacterial-induced effect was found for biomass production, and the soil inoculation treatment (using 10(6) CFUs mL(-1)) led to the highest increase in shoot dry weight yield (up to 45%). Bacterial-induced effects on shoot metal concentrations were less pronounced; although a positive effect was found on shoot Pb concentration when using 10(8) CFUs mL(-1) in the soil inoculation (29% increase) and in the seed+soil inoculation (34% increase). Also shoot Zn concentration increased by 24% after seed inoculation with 10(6) CFUs mL(-1). The best effects on the total metal yield were not correlated with an increasing number of inoculated bacteria. In fact the best results were found after a single soil inoculation using the lower cellular density of 10(6) CFUs mL(-1).

Abstract
AIM To evaluate the safety and efficacy of multimodal endovascular treatment (EVT) of acute basilar artery occlusion (BAO), including bridging therapy [intravenous thrombolysis (IVT) with subsequent EVT], to compare particular EVT techniques and identify predictors of clinical outcome. MATERIALS AND METHODS This retrospective, multi-centre study comprised 72 acute ischaemic stroke patients (51 males; mean age 59.1 ± 13.3 years) with radiologically confirmed BAO. The following data were collected: baseline characteristics, risk factors, pre-event antithrombotic treatment, neurological deficit at time of treatment, localization of occlusion, time to therapy, recanalization rate, post-treatment imaging findings. Thirty- and 90-day outcomes were evaluated using the modified Rankin scale with a good clinical outcome defined as 0-3 points. RESULTS Successful recanalization was achieved in 94.4% patients. Stepwise binary logistic regression analysis identified the presence of arterial hypertension (OR = 0.073 and OR = 0.067, respectively), National Institutes of Health Stroke Scale (NIHSS) at the time of treatment (OR = 0,829 and OR = 0.864, respectively), and time to treatment (OR = 0.556 and OR = 0.502, respectively) as significant independent predictors of 30- and 90-day clinical outcomes. CONCLUSION Data from this multicentre study showed that multimodal EVT was an effective recanalization method in acute BAO. Bridging therapy shortens the time to treatment, which was identified as the only modifiable outcome predictor.

Abstract
Abstract
Background
Silent infarction in the brain can be detected in around 34 per cent of patients after carotid endarterectomy (CEA) and 54 per cent after carotid angioplasty and stenting (CAS). This study compared the risk of new infarctions in the brain in patients undergoing CEA or CAS.
Methods
Consecutive patients with internal carotid artery (ICA) stenosis exceeding 70 per cent were screened for inclusion in this prospective study. Patients with indications for intervention, and eligible for both methods, were allocated randomly to CEA or CAS. Neurological examination, cognitive function tests and MRI of the brain were undertaken before and 24 h after intervention.
Results
Of 150 randomized patients, 73 (47 men; mean age 64·9(7·1) years) underwent CEA and 77 (58 men; 66·4(7·5) years) had CAS. New infarctions on MRI were found more frequently after CAS (49 versus 25 per cent; P = 0·002). Lesion volume was also significantly greater after CAS (P = 0·010). Multiple logistic regression analyses identified intervention in the right ICA as the only independent predictor of brain infarction (odds ratio 2·10, 95 per cent c.i. 1·03 to 4·25; P = 0·040). Stroke or transient ischaemic attack occurred in one patient after CEA and in two after CAS. No significant differences were found in cognitive test results between the groups.
Conclusion
These data confirm a higher risk of silent infarction in the brain on MRI after CAS in comparison with CEA, but without measurable change in cognitive function. Registration number: NCT01591005 (http://www.clinicaltrials.gov).

Abstract
BACKGROUND AND PURPOSE Increased echogenicity of the substantia nigra is a typical transcranial sonography finding in Parkinson disease. Experimental software for digital analysis of the echogenic substantia nigra area has been developed. The aim of this study was to compare the evaluation of substantia nigra echogenicity by using digital analysis with a manual measurement in patients with Parkinson disease and healthy volunteers. MATERIALS AND METHODS One hundred thirteen healthy volunteers were enrolled in the derivation cohort, and 50 healthy volunteers and 30 patients with Parkinson disease, in the validation cohort. The substantia nigra was imaged from the right and left temporal bone window by using transcranial sonography. All subjects were examined twice by using different sonographic machines by an experienced sonographer. DICOM images of the substantia nigra were encoded; then, digital analysis and manual measurement of the substantia nigra were performed. The 90th percentile of the derivation cohort values was used as a cut-point for the evaluation of the hyperechogenic substantia nigra in the validation cohort. The Spearman coefficient was used for assessment of the correlation between both measurements. The Cohen κ coefficient was used for the assessment of the correlation between both measurements and Parkinson disease diagnosis. RESULTS The Spearman coefficient between measurements by using different machines was 0.686 for digital analysis and 0.721 for manual measurement (P < .0001). Hyperechogenic substantia nigra was detected in the same 26 (86.7%) patients with Parkinson disease by using both measurements. Cohen κ coefficients for digital analysis and manual measurement were 0.787 and 0.762, respectively (P < .0001). CONCLUSIONS The present study showed comparable results when measuring the substantia nigra features conventionally and by using the developed software.

Abstract
In the middle of Europe, the Alps form a geographical and meteorological trap for atmospheric pollutants including volatile and semi-volatile organic compounds emitted in the surrounding lowlands. This is due to their barrier effects, high precipitation rates, and low ambient temperatures. Also the pollutants emitted in the cities inside the Alps spread in the region depending on orographic and meteorological conditions. Although a number of studies on the distribution and effect of pollutants in the Alps has been published, comprehensive information on potential hazards, and ways to improve this sensible environment are lacking. This opinion paper is the result of a discussion during the Winterseminar of the AlpsBioCluster project in Munich. It summarizes the current literature and presents some case studies on local pollution sources in the Alps, and the possibility of using biomonitoring techniques to assess critical pollution loads and distributions.

Abstract
BACKGROUND AND PURPOSE Sonolysis is a new therapeutic procedure for arterial recanalization. The aim of this study was to confirm the safety and efficacy of endovascular sonolysis by using the EkoSonic Endovascular System in subjects with acute ischemic stroke. MATERIALS AND METHODS Patients with acute ischemic stroke with occlusion of the middle cerebral artery or basilar artery were enrolled consecutively in this prospective study. The control group (44 MCA and 12 BA occlusions) was selected from historical controls. EkoSonic Endovascular System was started within 8 hours after stroke onset. The NIHSS score at hospital admission, after 24 hours, and at 7 days; arterial recanalization; early neurologic improvement; symptomatic intracerebral hemorrhage; and favorable 3-month clinical outcome defined as a modified Rankin Scale score of 0-2 were evaluated by statistical means. RESULTS Fourteen patients (10 men; mean age, 65.1 ± 11.2 years; median NIHSS score, 16.5) underwent EkoSonic endovascular sonolysis. Arterial recanalization after endovascular treatment was achieved in 6 of 7 (85.7%) patients with MCA occlusion (4 complete recanalizations) and in all 7 (100%) patients with BA occlusion (6 complete recanalizations). No (0%) symptomatic intracerebral hemorrhage or periprocedural complications occurred. Seven (50%) patients were independent at 3 months (median mRS score, 2). Early neurologic improvement and favorable clinical outcome were significantly more frequent in patients with MCA occlusion undergoing EkoSonic endovascular sonolysis than in controls (100% and 71.4% versus 4.6% and 13.6% of patients; P = .0001 and P = .003, respectively). Three-month mortality was significantly lower in patients with BA occlusion undergoing EkoSonic endovascular sonolysis than in controls (0% versus 66.7% patients, P = .013). CONCLUSIONS In this small study, EkoSonic endovascular sonolysis allowed safe and potentially effective revascularization in patients experiencing acute ischemic stroke.

Abstract
To assess the efficacy of hyperhydration Versus hyperhydration plus mesna in preventing cyclophosphamide induced hemorrhagic cystitis a retrospective analysis was conducted of 110 patients who received hyperhydration alone (baseline intravenous intake of at least 3.6 1/m(2)/day) and 107 patients who received hyperhydration plus mesna (120% of daily cyclophosphamide dose) while receiving cyclophosphamide (total dose 150-200 mg/kg) as part of a dose intensive regimen. Macroscopic hematuria was noted in 17 (16%) and 9 (8%) patients who received hyperhydration with or without mesna, respectively (p=0.08). This analysis failed to demonstrate a benefit in adding mesna to hyperhydration alone in preventing cyclophosphamide induced hemorrhagic cystitis.

Abstract
OBJECTIVES Intravenous thrombolysis (IVT) is considered an effective treatment for acute ischemic stroke (IS). However, not all treated patients may achieve good outcome. The aim was to evaluate whether the initial NIHSS and DWI infarct volume could be the predictors for good outcome after IVT. PATIENTS AND METHODS The set of 125 patients with consecutive hemispheric IS (78 men; mean age 66.0 ± 12.1 years) treated with IVT within 3 h was analyzed. DWI volume was measured on admission. Good outcome was defined as a score 0-2 in modified Rankin Scale. RESULTS Multivariate logistic regression analysis showed initial NIHSS as an independent predictor of good outcome (P = 0.001). ROC curves showed baseline NIHSS ≤13.5 points and DWI volume ≤13.7 ml as cut-offs related to good outcome. CONCLUSIONS The initial NIHSS and DWI volume might be the predictors for good clinical outcome in acute stroke patients treated with IVT. The initial NIHSS score seems to be more accurate.

Abstract
Use of sunflower (Helianthus annuus L.) for Cu phytoextraction and oilseed production on Cu-contaminated topsoils was investigated in afield trial at a former wood preservation site. Six commercial cultivars and two mutant lines were cultivated in plots with and without the addition of compost (5% w/w) and dolomitic limestone (0.2% w/w). Total soil Cu ranged from 163 to 1170 mg kg(-1). In soil solutions, Cu concentration varied between 0.16-0.93 mg L(-1). The amendment increased soil pH, reduced Cu exposure and promoted sunflower growth. Stem length, shoot and capitulum biomasses, seed yield, and shoot and leaf Cu concentrations were measured. At low total soil Cu, shoot Cu mineralomass was higher in commercial cultivars, Le., Salut, Energic, and Countri, whereas competition and shading affected morphological traits of mutants. Based on shoot yield (7 Mg DW ha(-1)) and Cu concentration, the highest removal was 59 g Cu ha(-1). At high total soil Cu, shoot Cu mineralomass peaked for mutants (e.g., 52 g Cu ha(-1) for Mutant 1 line) and cultivars Energic and Countri. Energic seed yield (3.9 Mg air-DW ha(-1)) would be sufficient to produce oil Phenotype traits and shoot Cu removal depended on sunflower types and Cu exposure.

Abstract
Authors report a case of young female suffering from the acute ischaemic stroke with right-sided hemiplegia, hemianopsia and hemihypoaesthesia during a migrainous attack without aura. Magnetic resonance imaging detected infarction in the left occipital lobe and occlusion of branches of the posterior cerebral artery (PCA). Combined treatment with systemic thrombolysis and sonothrombolysis was used, leading to the early PCA recanalization, and to a favourable clinical outcome after 1 month. Intravenous thrombolytic treatment administered within the therapeutic window may be useful in cerebral ischaemia associated with migraine when an arterial occlusion is documented.

Abstract
OBJECTIVES The aim of our work was to assess the role of tau protein, beta amyloid and cystatin C in diagnosis of Alzheimer dementia (AD) and other neurodegenerative diseases (NDs). METHODS The levels of tau protein, beta amyloid and cystatin C were assessed in a set of 79 patients with ND (38 men and 41 women; aged 22-90 years; mean, 61.6 +/- 15.6 years) and in a control group of 79 subjects with a healthy central nervous system (38 men and 41 women; aged 20-91 years; mean, 61.5 +/- 15.1 years). RESULTS When compared with the subjects in the control group, a statistically significant decrease in tau protein levels was found in patients with ND, an increase in tau protein levels in patients with AD and an increase in cystatin C cerebrospinal fluid/serum index in the ND + AD group. DISCUSSION Our work only confirmed the previously reported results in part. Although tau protein seems to be a quite reliable marker of AD, the role of beta amyloid in AD diagnosis remains at the least questionable. In the case of cystatin C, our results would seem to confirm the views of certain authors that cystatin C will probably not become a new 'revolutionary' marker contributing to differential diagnostics.

Abstract
7019 Background: Aptamers are small synthetic oligonucleotides that form stable nuclease-resistant 3D structures and bind target proteins with specificity and affinity similar to antibodies. These “chemical antibodies” represent a new class of therapeutics. The AS1411 aptamer binds nucleolin on the surface of cancer cells and induces apoptosis. AS1411 has synergistic effects in combination with cytarabine on AML cell lines in vitro and in vivo. A phase I trial of AS1411 monotherapy in 30 patients with advanced cancer showed objective responses without serious toxicities. Methods: This open-label randomized phase II trial compared AS1411 plus high-dose cytarabine (HiDAC) with HiDAC alone in patients with primary refractory or relapsed AML who had received up to 3 previous lines of chemotherapy. Patients in cohort I were randomized 2:1 to receive AS1411 10 mg/kg/day as continuous IVI on days 1–7 + HiDAC 1.5 g/m2/ twice daily on days 4–7 or HiDAC alone for 4 days. Following safety assessment, a second cohort was randomized in a similar manner, with AS1411 escalated to 40 mg/kg/day. Objectives were comparison of response rates (CR+CRp), safety and tolerability between treatment groups. Results: Accrual has been completed, with 71 patients randomized: 22 to AS1411 10 mg/kg/day + HiDAC (AS1411–10), 26 to AS1411 40 mg/kg/day + HiDAC (AS1411–40) and 23 to HiDAC alone (control). Safety findings are currently available for 44 patients (AS1411–10, 21; AS1411–40, 9; control, 14). The main grade 3/4 toxicities were hematologic, notably febrile neutropenia, neutropenia, and thrombocytopenia; and infections. Safety findings were similar across groups, except that grade 3 hypokalemia was more frequent with AS1411–40. Deaths within 28 days of treatment were: AS1411–10, 1/21; AS1411–40, 1/9; and control, 2/14. Response data are currently available for 39 patients; response rates were: AS1411–10, 16% (3/19); AS1411–40, 14% (1/7); and control, 0% (0/13). Conclusions: Data from this first phase II trial of an aptamer in oncology are encouraging. The combination of AS1411 at 10 or 40 mg/kg/day with HiDAC appears well tolerated and shows promising signs of activity in patients with relapsed/refractory AML. [Table: see text]

Abstract
To assess the role of tau protein, beta-amyloid(1-42) and cystatin C in the diagnostics of Alzheimer dementia (AD) and other neurodegenerative diseases (ND) by comparing to the control groups (CG). The levels of tau protein, beta-amyloid(1-42) and cystatin C were assessed in the set of 69 patients (AD + ND, 33 males, 36 females, aged 22-90, mean 60.5 + 16.1 years), and in a control group of 69 subjects without the affection of the central nervous system (CGAD + CGND, 33 males, 36 females, aged 20-91, mean 60.5 + 16.0 years). Statistically significant increased tau protein levels (P = 0.0001) and index tau/beta-amyloid(1-42) levels (P = 0.0002) were shown in the group of AD patients, compared to the group of ND patients. One-way ANOVA analysis with Bonferonni post hoc test did not show any significant differences of the cystatin C values between any of the compared groups. ROC analysis showed at least one tie between the positive actual state group (AD) and the negative actual state group (ND) by CSF cystatin C and at least one tie between the positive actual state group and the negative actual state group by CSF tau protein. Our study confirmed previously reported results only in part. While tau protein seems to be quite a reliable marker of AD, the role of beta-amyloid(1-42) and cystatin C in AD diagnosis remains at least questionable.

Abstract
The role of diabetes mellitus (DM) in the etiopathogenesis of spontaneous intracerebral hemorrhage (SICH) is controversial. The aim was to assess the role of DM in our SICH patients. In a hospital-based cross-section study, the occurrence of DM prior to a hemorrhagic stroke was observed in 80 SICH patients (44 males, aged 36-87 years, mean 67.1 +/- 11.9 years; 36 females, aged 56-86 years, mean 71.1 +/- 8.3 years), and in a control group (CG) of 80 age- and sex-matched patients with low back pain. All patients were treated at the Departments of Neurology and Neurosurgery, University Hospital, Olomouc, Czech Republic. Two-sample t test and Pearson's homogeneity chi(2) test were applied when assessing statistical significance. DM was found in 37.5% of SICH patients versus 22.5% of CG subjects (P < 0.05). DM occurs significantly more frequently in SICH patients in the Olomouc region of the Czech Republic when compared to the general population.

Abstract
17537 Background: The prognosis of pts with recurrent ML remains poor. High-dose therapy (HDT) with HC rescue can cure a proportion of such pts. HC mobilization can be adversely affected by number and duration of prior treatments, interval from diagnosis to HC collection, prior radiotherapy and marrow involvement. There remains a need for more effective and less toxic salvage regimens, capable of mobilizing HCs. Methods: The mobilizing potential of R-GVM salvage regimen with hematopoietic growth factor (HGF) support (G- and GM-CSF) was evaluated in 6 pts with relapsed (n=5) or primary refractory (n=1) ML. Pts received R-GVM salvage therapy [rituximab (375 mg/m2, day 1), gemcitabine (1 g/m2, day 1, 8), vinorelbine (30 mg/m2, day 1, 8) and methylprednisone (1 g/m2, day 1, 8)] with HGF administration and subsequent HC collection. The HGF support was started on day 9 and was continued through apheresis which started when the CD34+ cell count ≥ 20/μl (median day of R-GVM cycle: 15, range 14–19). Pts had daily apheresis with continued HGF support until at least 5 x 106 CD34+ cells/kg were collected. The hematologic and non-hematologic toxicity were tolerable in all pts; no pt required hospitalization. Results: 6 pts (age range 20–45 years) with Hodgkin (n =3) and non- Hodgkin lymphoma (n =3) were evaluated in this study. Pts had received 1–3 previous treatment regimens. The median number of R-GVM courses given before HC collection was 2.5 (range 1–5). Effective HC mobilization (≥5x106 CD34+ cells/kg) was obtained in all ps. A single apheresis resulted in satisfactory HC collection in 4 pts (range 8.2–17.7 x 106 CD34+ cells/kg); 2 pts required 3 aphereses to collect an adequate number of cells (6.7 and 7.4 x 106 CD34+ cells/kg). One pt was heavily pretreated and had failed two previous attempts of HC mobilization (one with HGF alone and one with cyclophosphamide and HGF); the other pt was HIV+ treated with HAART and had prior marrow involvement. As a salvage regimen, one pt had progressive disease, 1 had stable disease, 1 had a partial response, and 3 had a complete response before proceeding with HDT with HC rescue. Conclusions: R-GVM regimen is feasible, tolerable and effective in mobilizing HPC in patients with relapsed and refractory lymphoma. No significant financial relationships to disclose.

Abstract
The response of tobacco plants (Nicotiana tabacum L.)--non-transformed and transformed with a metallothionein gene MThis from Silene vulgaris L.--to increase cadmium supply in the nutrient solution was compared. The transgenic plants accumulated significantly more Cd both in the roots and the leaves. Visual toxicity symptoms and disturbance in water balance were correlated with Cd tissue content. Treatment with 300 microM CdCl(2) resulted in inhibition of photosynthesis and mobilization of the ascorbate-glutathione cycle. Treatment with 500 microM CdCl(2) led to irreversible damage of photosynthesis and oxidative stress. An appearance of a new peroxidase isoform and changes in the leaf polypeptide pattern were observed at the highest Cd concentration. The level of non-protein thiols gradually increased following the Cd treatment both in transgenic and non-transformed plants.

Abstract
Cerebral aneurysms and arteriovenous malformations (AVMs) are well-known sources of intracranial hemorrhage, but can also manifest as other clinical symptoms or remain clinically asymptomatic. The aim was to document and analyze cases of aneurysm or AVM with brain infarction. Survey on 4804 stroke patients treated at the Department of Neurology, Centre Hospitalier Universitaire Vaudois, Lausanne, Switzerland between 1978 and 2000 using the Lausanne Stroke Registry. Twenty patients presented with cerebral aneurysm and 21 with cerebral AVM. Hemorrhage was present in 100% of the AVM and in 75% of the aneurysm patients; in one (5%) of the remaining aneurysm patients, aneurysm and infarction were located in different territories. Infarction associated with Sylvian artery aneurysm was found in three (15%), vertebrobasilar ischemia because of fusiform left vertebral artery aneurysm in one (5%), and dural fistula draining to the distal transversal and left sigmoid sinus associated with a stroke in the territory of the left anterior inferior cerebellar artery in one patient. Ischemic stroke is infrequent, but important, complication in unruptured intracranial aneurysms and AVMs. The early recognition and therapy of these vascular malformations in selected patients can avoid a major neurological deficit or death caused by their rupture.

Abstract
Digital subtraction angiography (DSA) is considered to be the 'gold standard' for confirmation of severe (70-99%) stenoses of internal carotid arteries (ICAs). However, it is associated with a risk of complications. The aim of this study was to assess the accuracy of ultrasonography (US), computed tomographic angiography (CTA), and their combined use for the detection and quantification of severe carotid stenoses, when compared with DSA. Severe ICA stenoses were diagnosed by US in a set of 29 patients. All patients also underwent CTA and DSA. Sensitivity, specificity, positive (PPV), negative predictive values (NPV), and Pearson's correlation coefficient were used in the evaluation of the percentage of stenosis results. Homogeneity chi2 test was applied when assessing statistical significance. Severe stenosis was diagnosed in 34 ICAs. Two ICAs with uninterpretable CTA finding were excluded. The number of ICAs with stenoses 70-99%/<70%- US 32/0; CTA 29/3; US + CTA 29/3; DSA 24/8. Pearson's correlation coefficient - US 0.601; CTA 0.725; US + CTA 0.773. Sensitivity/specificity/PPV/NPV - US 1.0/0.75/0.75/xxx; CTA 1.0/0.844/0.828/1.0; US + CTA 1.0/0.844/0.828/1.0. Homogeneity chi2 test results - US, P = 0.002; CTA, P = 0.098; US + CTAG, P = 0.098. US in combination with CTA can be used for relatively secure diagnostics of severe ICA stenoses. Thus, invasive DSA can be avoided in a substantial number of patients.

Abstract
BACKGROUND AND PURPOSE Stroke is the third most common cause of death in the Czech Republic (CR). Specialized in-patient stroke unit care improves the outcome of stroke patients. The aim of the study was to chart and improve the current facilities. METHODS Neurological in-patient departments exist in 75% of the districts in the CR, and in the capital Prague. Questionnaires were sent to all 79 neurological in-patient departments. A chi2 test was used for the evaluation of statistical significance. RESULTS There is better access to intensive/intermediary care beds (statistically not significant) and to angiography (statistically significant) in the districts with a population density of over 151 inhabitants per km2 than in districts with a lower population density (p = 0.09 and p = 0.008). Stroke patients have access within 1 hour to computed tomography of the brain in all but one, and to laboratory tests in all districts with a neurological in-patient department(s). There is no statistically significant difference in the availability of ultrasound examination of extracranial brain arteries between the sparse, and more populated districts (p = 0.715). CONCLUSIONS Facilities for the establishment of stroke units are quite good in the majority of highly populated areas; however, they are worse in some of the larger towns. The results of the study must be used to further improve the development of stroke care in the CR.

Abstract
Thrombocytopenia following myelotoxic therapy is a common problem and when severe (<20,000/microl) can lead to severe morbidity and mortality. Thrombopoietin (TPO) is a naturally occurring glycosylated peptide which stimulates the differentiation of bone marrow stem cells into megakaryocyte progenitor cells, induces the expression of megakaryocyte differentiation markers, promotes megakaryocyte proliferation, polyploidization and, ultimately, the formation of increased numbers of platelets in the circulation. TPO has now been produced by recombinant technology and has entered clinical trials. This open label phase I study was designed to determine the safety, tolerance and pharmacokinetics of recombinant thrombopoietin (rhTPO) when administered to patients after undergoing high-dose chemotherapy followed by autologous bone marrow transplantation. rhTPO was administered intravenously by bolus injection at doses ranging from 0.3 to 4.8 microg/kg/day every 3 days to 30 patients and 0.6 microg/kg daily to three patients. rhTPO was begun the day after marrow infusion and continued until platelet recovery to >20,000/microl. G-CSF was concomitantly administered to promote myeloid recovery. Serious adverse events or neutralizing antibodies to rhTPO were not observed during the study. Median platelet recovery after ABMT was 19 days (range, 11-41). Neither the dose nor the schedule of rhTPO appeared to have any impact upon the time course of platelet recovery. In this phase I study, rhTPO was found to be well tolerated without the development of neutralizing antibodies and without compromising neutrophil recovery. Platelet recovery was similar for all doses studied warranting further evaluation in phase II and III trials designed to test for platelet recovery efficacy.

Abstract
Cerebral arteriovenous malformations (AVMs) are considered to be congenital disorders. However, their familial occurrence has so far been described in only 19 families in the literature. The authors report on two cases in one family and review the literature. A 45-year-old female subject with sudden onset of headache and vomiting due to a subarachnoid haemorrhage from a small AVM in the posterior part of the corpus callosum near the midline on the left side was studied. Irradiation of the AVM using Leksell's gamma knife led to its complete obliteration. Her older sister presented with temporal seizures at the age of 49 and later also with left hemiparesis, left hemihypaesthesia and dizziness - caused by a large AVM in the right temporal lobe. This AVM was treated by a combination of embolization and irradiation by the Leksell's gamma knife.
