The Usefulness of Factor XIII Concentration Assessment in Patients in the Acute Phase of Ischaemic Stroke Treated with Thrombolysis.

BACKGROUND AND AIMS: In recent years, there has been a growing interest in factor XIII in ischaemic stroke. The study's main aim was to assess the usefulness of factor XIII concentration determination in patients with acute ischaemic stroke (AIS) treated with thrombolysis with recombinant tissue plasminogen activator (t-PA). METHODS: The study was conducted in two groups of 84 patients with AIS: group I-with thrombolytic therapy and group II-without thrombolysis. A physical examination, neurological status (using the National Institutes of Health Stroke Scale, NIHSS), daily patients' activities measured with the Barthel Index and Modified Rankin Scale (mRS), and blood parameters were conducted on day 1 and day 7. The following parameters were assessed: highly sensitive C-reaction protein (CRP), fibrinogen, D-dimers (DD), neutrophil-lymphocyte ratio (NLR index), and the concentration of factor XIII-A. RESULTS: In group I, the concentration of XIII-A decreased significantly between day 1 and 7 (p < 0.001). In group I, the concentration of XIII-A on day 7 in Total Anterior Circulation Infarct (TACI) was significantly lower than in non-TACI stroke. XIII-A concentration in group I was significantly lower in patients < 31 points with Acute Stroke Registry and Analysis of Lausanne (ASTRAL). A greater decrease in XIII-A between the first sampling on day 1 and the second sampling on day 7 was associated with a worse patient neurological state in group I. CONCLUSIONS: In patients with AIS treated with t-PA, factor XIII concentrations decrease in the acute phase of stroke, and the largest decrease occurs in the TACI stroke. Determination of factor XIII concentration in patients with AIS can be used in clinical practice as an additional parameter supporting the assessment of stroke severity and may play a role in the prognosis; lower factor XIII-A activity may be a predictor of a worse prognosis.

External quality monitoring facilitates improvement in already well-performing stroke units: insights from RES-Q Poland.

INTRODUCTION: The Registry of Stroke Care Quality (RES-Q) is used in Poland for quality monitoring by numerous hospitals participating in the Angels Initiative. Our aim was to assess the degree of improvement in highly stroke-oriented centres that report cases to the RES-Q each year. MATERIAL AND METHODS: This retrospective analysis included Polish stroke units that from January 2017 to December 2020 contributed to the RES-Q at least 25 patients annually. RESULTS: Seventeen out of 180 Polish stroke units reported patients each year (2017, n = 1,691; 2018, n = 2,986; 2019, n = 3,750; 2020, n = 3,975). The percentage of ischaemic stroke patients treated with alteplase remained stable (26%, 29%, 30% and 28%, respectively). The door-to-needle time progressively decreased, from a median 49 minutes to 32 minutes. The percentage of patients treated ≤ 60 minutes and ≤ 45 minutes significantly increased (from 68% to 86% and from 43% to 70%, respectively), with no change observed between 2019 and 2020. Despite a general improvement in dysphagia screening (81%, 91%, 98% and 99%), screening performed within the first 24h from admission became less frequent (78%, 76%, 69% and 65%). In-hospital mortality significantly increased (11%, 11%, 13% and 15%), while the proportion of patients discharged home remained stable. CONCLUSIONS: Quality-oriented projects facilitate the improvement of stroke care, even in centres demonstrating good baseline performance. Polish stroke units that consistently reported cases to the RES-Q demonstrated improvement in terms of door-to- -needle time and dysphagia screening. However, there is still a need to shorten the time to dysphagia screening, and carefully monitor stroke unit mortality following the COVID-19 pandemic.

Headache and NOTCH3 Gene Variants in Patients with CADASIL.

Autosomal dominant cerebral arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited vascular disease characterized by recurrent strokes, cognitive impairment, psychiatric symptoms, apathy, and migraine. Approximately 40% of patients with CADASIL experience migraine with aura (MA). In addition to MA, CADASIL patients are described in the literature as having migraine without aura (MO) and other types of headaches. Mutations in the NOTCH3 gene cause CADASIL. This study investigated NOTCH3 genetic variants in CADASIL patients and their potential association with headache types. Genetic tests were performed on 30 patients with CADASIL (20 women aged 43.6 ± 11.5 and 10 men aged 39.6 ± 15.8). PCR-HRM and sequencing methods were used in the genetic study. We described three variants as pathogenic/likely pathogenic (p.Tyr189Cys, p.Arg153Cys, p.Cys144Arg) and two benign variants (p.Ala202=, p.Thr101=) in the NOTCH3 gene and also presented the NOTCH3 gene variant (chr19:15192258 G>T), which has not been previously described in the literature. Patients with pathogenic/likely pathogenic variants had similar headache courses. People with benign variants showed a more diverse clinical picture. It seems that different NOTCH3 variants may contribute to the differential presentation of a CADASIL headache, highlighting the diagnostic and prognostic value of headache characteristics in this disease.

Stroke in the COVID-19 pandemic era.

Purpose: The aim of this article is to outline the impact of COVID-19 on the frequency of occurrence, course of stroke treatment, and to highlight the cause-effect relationship between SARS-CoV-2 infection and stroke on the basis of a literature overview. Views: Since the end of 2019, the whole world has been struggling with the effects of the pandemic caused by the coronavirus SARS-CoV-2. The virus induces a wide spectrum of symptoms, ranging from mild or serious ones, which may lead to a severe multiorgan failure. Acute ischaemic stroke (AIS) might be associated with COVID-19 as a potentially fatal complication, while hemorrhagic stroke is less frequent. In most cases, stroke is caused by large artery occlusion. One of its reasons is hypercoagulation with a complex mechanism, which has not been fully explained. Research has shown that during COVID-19 pandemic, the number of patients admitted to hospitals due to AIS decreased. During the first pandemic wave there was no change regarding the proportion of patients with cerebral vessel obstruction who received endovascular treatment. Conclusions: In the COVID-19 pandemic era, rapid intravenous administration of tissue plasminogen activator remains the main treatment for acute ischaemic stroke. Patients often fail to report to hospital for the fear of SARS-CoV-2 infection. It is of the utmost importance to raise society's awareness of the necessity to report to hospital when experiencing serious symptoms, including stroke.

Analysis of Genetic Variants in SCN1A, SCN2A, KCNK18, TRPA1 and STX1A as a Possible Marker of Migraine.

BACKGROUND: Migraine is a polygenetic disease, considered as a channelopathy. The dysregulation of ion functioning due to genetic changes may activate the trigeminovascular system and induce migraine attack both migraine with aura (MA) and without aura (MO). OBJECTIVES: The aim of the study was to analyze the following variants of genes encoding ion channels and associated protein: c.3199G>A SCN1A, c.56G>A SCN2A, c.28A>G and c.328T>C KCNK18, c.3053A>G TRPA1, c.31-1811C>T STX1A in migraine patients. PATIENTS AND METHODS: The study included 170 migraine patients and 173 controls. HRMA and Sanger sequencing were used for genotyping. Meta-analysis was performed for c.28A>G, c.328T>C KCNK18, and c.31-1811C>T STX1A. RESULTS: AA genotype of c.56G>A SCN2A was found only in migraine patients. Patients with c.328T>C KCNK18 mutation had an increased risk of developing migraine before the age of 18. Moreover, individuals with AA/TC haplotype of KCNK18 had higher attack frequency than those with AA/TT (p<0.05). T allele of c.31-1811C>T STX1A was more frequent in MA patients than MO (p<0.05). The c.3053A>G TRPA1 polymorphism was more common in patients with migraine onset before the age of 15 (p<0.05), while c.31-1811C>T STX1A and c.3199G>A SCN1A before the age of 10 (p<0.01). Meta-analysis showed a significant association of c.31-1811C>T STX1A polymorphism with migraine overall (OR=1.22, p=0.0086), MA, and MO. No association was found for c.28A>G KCNK18, c.328T>C KCNK18, and migraine overall. CONCLUSION: Changes in genes encoding ion channels or proteins regulating their functioning may increase the risk of migraines and correlate with clinical features of disease, e.g. age of onset and attack frequency.

Sex-related differences among ischaemic stroke patients treated with intravenous thrombolysis in Poland.

AIM OF STUDY: We investigated sex differences i n i schaemic s troke p atients t reated w ith i ntravenous a lteplase. CLINICAL RATIONALE FOR STUDY: We suggest that it is necessary to improve care for women with atrial fibrillation. Our data suggests that closer evaluation of treatment for ischaemic stroke in men and women is needed, preferably in the form of a prospective study. MATERIALS AND METHODS: This was a multicentre analysis of 1,830 ischaemic stroke patients treated with alteplase from 2004 to 2012. Data was prospectively collected in the Safe Implementation of Treatments in Stroke (SITS) registry. The main outcome measures were symptomatic intracerebral haemorrhage (sICH) within 36 hours of treatment, three months of functional independence, and mortality. RESULTS: Women were significantly older (mean age 71.3 vs 66.2 years; p < 0.01), more often suffered from hypertension (78.3% vs 70.1%; p < 0.01) and cardio-embolic strokes (34.7% vs 27.1%; p < 0.01), and presented heavier baseline deficits. There were no differences in sICH, but after three months fewer women were functionally independent (46.5% vs 53.3%; p < 0.01) and women had higher mortality (26.0% vs 19.7%; p < 0.01). CONCLUSIONS: Of the ischaemic stroke patients treated with intravenous thrombolysis, women had worse long-term outcomes than men. This discrepancy may be explained by the older age and higher proportion of cardio-embolic strokes with more severe baseline deficits. However, multiple logistic analysis did not show that sex itself had an impact on the greater mortality in women after a stroke, or on the poorer prognosis.

Biothiols and oxidative stress markers and polymorphisms of TOMM40 and APOC1 genes in Alzheimer's disease patients.

Alzheimer's disease (AD) is a progressive disease, with frequently observed improper biothiols turnover, homocysteine (Hcy) and glutathione (GSH). GSH protects cells from oxidative stress and may be determined by 8-oxo-2'-deoxyguanosine (8-oxo2dG) level and its repair enzyme 8-oxoguanine DNA glycosylase (OGG1). The presence of unfavorable alleles, e.g., in APOE cluster, TOMM40 or APOC1 is known to facilitate the dementia onset under oxidative stress. The aim of the study was to analyze rs1052452, rs2075650 TOMM40 polymorphisms, rs4420638 APOC1, and their correlation with Hcy, GSH, 8-oxo2dG, OGG1 levels in plasma of AD patients and controls. We recruited 230 individuals: 88 AD, 80 controls without (UC), 62 controls with (RC) positive family history of AD. The TOMM40 genotype was determined by HRM and capillary electrophoresis, while APOC1 by HRM. The concentrations of OGG1, 8-oxo2dG were determined by ELISA, whereas Hcy, GSH by HPLC/EC. We showed that over 60% of AD patients had increased Hcy levels (p<0.01 vs. UC, p<0.001 vs. RC), while GSH (p<0.01 vs. UC), 8-oxo2dG (p<0.01 vs. UC, p<0.001 vs. RC) were reduced. Minor variants: rs10524523-L, rs4420638-G, rs2075650-G were significantly overrepresented in AD. For rs4420638-G, rs2075650-G variants, the association remained significant in APOE E4 non-carriers. The misbalance of analyzed biothiols, and 8-oxo2dG, OGG1 were more pronounced in carriers of major variants: rs10524523-S/VL, rs4420638-A, rs2075650-A. We showed, for the first time, that APOC1 and TOMM40 rs2075650 polymorphisms may be independent risk factors of developing AD, whose major variants are accompanied by disruption of biothiols metabolism and inefficient removal of DNA oxidation.

Intravenous thrombolysis with rt-PA for acute ischemic stroke within 24h of a transient ischemic attack.

BACKGROUND: Intravenous thrombolysis (iv-thrombolysis) with the use of rt-PA in patients after recent transient ischemic attack (TIA) is an important clinical problem. The aim of the study was to assess the impact of TIA within 24h preceding acute ischemic stroke (AIS) on the safety and efficacy of iv-thrombolysis. METHODS: We retrospectively evaluated the clinical and demographic data of 400 patients with AIS who were consecutively treated with iv-thrombolysis from September 2006 to May 2011 in three stroke centers. RESULTS: At three-month follow-up, 58.0% of patients were independent (modified Rankin scale; mRS 0-2), 17.8% had died, 17.0% suffered hemorrhagic transformation (HT) and 4.3% experienced symptomatic intracerebral hemorrhage (SICH). There were 29 patients (7.3%) who had a previous ipsilateral TIA within 24h before established stroke. In the TIA subgroup, there was no significant higher percentage of favorable outcome (p=0.07) and higher SICH rate (p=0.15). Multivariate analysis showed the impact of prior TIA within 24h before stroke onset in the presence of SICH (p=0.01), no impact of TIA on unfavorable outcomes after three months (p=0.25) and on the mortality rate within three months (p=0.41). CONCLUSION: TIA within 24h prior to ischemic stroke can portend severe intracerebral bleeding in patients qualified to iv-thrombolysis with the use of rt-PA.

Ischemic stroke due to postpartum angiopathy complicated by pulmonary embolism with favorable outcome.

Postpartum cerebral angiopathy is a relatively rare condition. It can cause either ischemic or hemorrhagic stroke, or both, and usually occurs within the first week following non-complicated pregnancy and natural delivery. Although its pathophysiology is unclear, the cause of the condition is believed to be prolonged reversible vasospasm. We present an unusual case of a 37-year-old woman who developed right hemiparesis with aphasia on day 8 of natural delivery complicated by pulmonary embolism. Steroids, heparin, and calcium channel blockers were successfully instituted and the patient was discharged from the hospital on day 50. The article presents clinical and imaging characteristics, differential diagnosis, management, and considers the difficulties that occurred during the patient's hospital stay.

Knowledge of risk factors and stroke symptoms among nonstroke patients.

BACKGROUND AND PURPOSE: This study aimed to evaluate knowledge of stroke warning signs, risk factors, treatment and prevention among patients not suffering from stroke. METHODS: Patients admitted to one of five Neurology Departments in Poland for diseases other than stroke were asked to answer a questionnaire regarding awareness of cerebrovascular risk factors and stroke. The study was performed between November 1 and December 31,2008. RESULTS: 481 patients were included in the study (59.7% women). Proper definition of stroke and transient ischemic attack was given by 90.3 and 60.5% of respondents, respectively. Hypertension was reported as a risk factor by 91.1% of participants. Approximately 70% knew that hypercholesterolemia and smoking are risk factors of stroke, but only one third identified diabetes mellitus as a risk factor. Cardiac arrhythmia was recognized as a risk factor by 8.4%. Twenty-five percent of participants did not know any symptom of stroke. Identification of stroke signs was worse by participants from rural areas. Ten percent identified disturbances of consciousness, numbness, and dizziness as stroke symptoms. CONCLUSIONS: The knowledge of fundamental risk factors was sufficiently good, but recognition of cardiac arrhythmia and diabetes mellitus was unsatisfactory. The knowledge of stroke symptoms was unsatisfactory, particularly in rural areas. Additional education programs are necessary.

Sex differences in risk factor distribution, severity, and outcome of ischemic stroke.

The aim of the study was to identify differences in baseline characteristics and outcomes of men and women with acute ischemic stroke. Ischemic stroke was confirmed by CT scan or autopsy in patients admitted to the 2nd Department of Neurology, Institute of Psychiatry and Neurology in Warsaw, Poland from 1995 to 2007. Male and female patients were compared for risk factors, state of activity prior to stroke, stroke type according to Oxfordshire Community Stroke Project classification, diagnostic test findings, and early 30-day outcome. Data on 1379 women and 1155 men admitted with ischemic stroke were analyzed. The mean age of female and male patients was 74.3 and 68.8 years, respectively. Women were more often disabled prior to stroke, hypertensive, diagnosed with atrial fibrillation or heart failure, and had impaired consciousness at admission, whereas men were more likely to smoke, abuse alcohol and have a history of myocardial infarction or transient ischemic attack. A higher percentage of female stroke patients suffered from total anterior circulation syndrome than males (21.2% and 14.0%, respectively). Internal carotid artery stenosis over 70% was reported in 10.8% ofwomen and 19.1% of men. The 30-day mortality and poor outcome rates were significantly higher in women than men (17.2% vs. 13.1% and 59.9% vs. 46.2%). After adjusting for casemix in multivariate analysis, female sex was independently associated with a higher risk of an early poor outcome. In conclusion, the risk factor distribution, clinical characteristics, diagnostic test findings, and early outcomes were different between female and male ischemic stroke patients. Female sex was associated with poorer prognosis, indicating that more intensive acute and long-term global care may be needed to improve the outcome among female stroke patients.

[Primary central nervous system vasculitis imitating a brain tumour--a case report]. / Pierwotne zapalenie naczyn osrodkowego ukladu nerwowego imitujace guz mózgu--opis przypadku.

Primary central nervous system vasculitis (PCNSV) is a rare disease with an annual incidence rate of 2.4 cases per 1,000,000 person-years. PCNSV causes various neurological symptoms dominated by headache as well as consciousness and mental disturbances. The disease sometimes imitates a brain tumour on CT and rarely presents as stroke. The diagnosis of PCNSV is difficult and frequently requires a brain biopsy in which transmural vascular inflammation involving leptomeningeal or parenchymal vessels is typically found. Angiographic changes indicating an irregular course of vessels with characteristic segmental narrowing can be observed but sometimes the angiogram is normal. The authors present a 57-year-old man in whom PCNSV was diagnosed in brain biopsy. The patient was treated with corticosteroid pulses for 18 months with good effect lasting for 2.5 years. After one year of ending glucocorticoid therapy the symptoms had occurred again and in spite of combined therapy of glucocorticoids with cyclophosphamide the patient died.

Giant cell arteritis as a cause of first-ever stroke.

The aims of this study were to assess how frequently giant cell arteritis (GCA) was a cause of first-ever stroke in 4,086 patients in the Lausanne Stroke Registry and to determine the risk factors, patterns, latency and current therapy at onset in patients with GCA plus stroke. GCA was recognized using the criteria of the American College of Rheumatology. We report on 6 patients (0.15%) with a histologically proven diagnosis of temporal arteritis and clinical and neuroradiological evidence of cerebral ischemia. The CT and MRI scans showed lacunar infarction in 3 patients, territorial infarction in 2 and were normal in 1. Stroke latency ranged from 0 to 2 months. All patients suffered from headache. We conclude that stroke is a rare, but dangerous, complication of GCA and that a combination of antiplatelet drugs and corticosteroids may be advisable for preventing stroke occurrence.

Alternative methods of treatment used by multiple sclerosis patients in Poland.

BACKGROUND AND PURPOSE: Despite the great progress that has been made in medicine, treatment of many chronic diseases, including multiple sclerosis (MS), remains hardly effective. It has been reported that more and more MS patients worldwide are using alternative methods (AM). The aim of the present study is to evaluate this phenomenon in the Polish MS population. MATERIALS AND METHODS: To obtain more data about use of AM in Poland we distributed questionnaires among 210 MS patients treated in 3 hospitals in different regions of our country: Warsaw, Gdansk and Pila. RESULTS: 210 patients (136 females and 74 males) took part in the study. 68.5% (144 of 210 questioned) declared use of AM now or in the past. The most popular (56%) was Oenothera seed oil, followed by vitamins (49%), and the third most common was massage (34%). There were no significant demographic differences between users and non-users. Neither disease duration nor disability had any impact on the decision to use AM. CONCLUSIONS: The phenomenon of use of AM by MS patients is not fully understood, but it seems that limited access to so-called immunomodulators, e.g. interferon-b or glatiramer acetate, and limited long-term efficacy are reasons why patients seek other therapies.

[Antiphospholipid syndrome--interdisciplinary problem]. / Zespól antyfosfolipidowy--problem interdyscyplinarny.

Antiphospholipid syndrome (APS) is a systemic autoimmune disorder, where the essence of the matter is the existence of antiphospholipid antibodies. The typical symptoms of APS are: venous thrombo-embolic disease and artery thrombosis in a brain. The authors present 5 patients (2 females and 3 males) at the age of 36-54 with ischemic stroke and one 26-year-old women with thrombosis of central retinal vein caused by APS. In 4 cases in secondary prevention anticoagulant (acenocumarol) was used and in 2--antiplatelet drug (aspirin). In 2 cases congenital disturbances of coagulation were also discovered. We suggest that in ischemic stroke and visual disturbances of not-well-known origin it is useful to make examinations concerning APS, as well as congenital thrombophilias.

[Guillain-Barré syndrome in a course of early cutaneous type of Lyme borreliosis: diagnostic and therapeutic difficulties]. / Zespól Guillaina-Barrégo w przebiegu wczesnej skórnej postaci boreliozy z Lyme -- problemy diagnostyczne i terapeutyczne.

A case is reported of a 33-year-old man in whom Guillain-Barré syndrome (GBs) developed three weeks after a tick's sting. At the sting site typical for an early cutaneous type of Lyme borreliosis -- erythema migrans -- appeared. The demyelinating polyradiculoneuropathy of GBs occurred after disappearance of erythema migrans, and was manifested by progressive neuropathic symmetrical limb weakness with distal numbness and pain, and bilateral facial paralysis. The GBs was confirmed by electrophysiological examination and elevated protein concentration with a normal range of cells in the cerebrospinal fluid. Antibodies IgM and IgG against Borrelia burgdorferi in the blood serum and cerebrospinal fluid assessed using immunoenzymatic assay, MEIA, were negative on account of their early search. The above findings suggested that the GBs appearance after the probable Borrelia burgdorferi infection was in fact due to that infection. The patient recovered after treatment with plasma-phoresis and corticosteroid therapy followed by intravenous immunoglobulin, and physiotherapy. This is the first case in the Polish neurological literature of GBs with an early skin form of borreliosis which developed after the tick's sting.

Exposure to moulds in flats and the prevalence of allergic diseases--preliminary study.

The presented study concerned mycological analysis of buildings in Lódz and evaluation of the role between filamentous fungi contaminated flats and inhabitants health (allergic airway diseases). 49 inhabitants of 20 flats with signs of moulds contamination were examined. Air samples were collected in houses and outdoors. In all inhabitants skin prick tests (SPT) to common allergens and to standardized particular fungal extracts were performed. Moreover, total and serum specific IgE to moulds, rest spirometry were measured in all subjects. Level of moulds contamination in the air of flats was high and in 75% cases exceed accepted limits. The most frequent species isolated from examined rooms were: Penicillium, Cladosporium, Aspergillus, Acremoniu and Alternaria. The most frequent symptoms reported by examined subjects were rhinitis (N = 29, 59.2%), conjunctivitis (N = 29, 59.2%), chronic cough (N = 24, 49%), dyspnea (N = 15, 30.6%) and skin symptoms (N = 24, 49%). Elevated IgE level was found in 12 subjects (24.5%) and in three patients (6.1%) mould specific serum IgE were detected. Nineteen out of all subjects (38.8%) had positive SPT to common allergens (house dust mites, grass and tree pollens). Eight out of these patients (16.3% of the group) were sensitized to moulds (Candida albicans, Alternaria alternata, Botrytis cinerea, Trichophyton mentagrophytes, Helminthosporium halodes, Aspergillus). In all cases sensitisation to moulds was accompanied by allergy to other common allergens. No isolated hypersensitivity to moulds was found. Although the frequency of self-reported symptoms was high, the prevalence of atopy and allergic diseases seems to be similar to that found in general population, but that statement must be confirmed by comparison of the control group.

[Can a cutaneous-muscular biopsy be helpful in the diagnosis of vasculitis in the stroke?]. / Czy biopsja skórno-miesniowa moze byc pomocna w rozpoznaniu zapalenia naczyn jako przyczyny udaru mózgowego?

Vasculitis includes a heterogeneous group of multisystemic disorders characterized pathologically by inflammation of blood vessels. The diagnosis of vasculitis is difficult and more often than not, it is made indirectly after eliminating other causes of the stroke. Vasculitis is an infrequent disorder and a rare cause of the stroke. This is a case report of a 41-year-old man who had the first-ever stroke with vasculitis diagnosed histologically in a cutaneous-muscular biopsy from the place not changed by the disease. After corticosteroid therapy the hemiparesis disappeared. The patient has continued the treatment with immunosuppressive drugs.

[Prognostic factors in the acute phase of haemorrhagic stroke]. / Czynniki prognostyczne w ostrym okresie krwotoku mózgowego.

The aim of the study was establishing which parameters play a significant prognostic role in acute haemorrhagic stroke in its acute phases (during 30 days from stroke onset). The material included 110 patients with haemorrhagic stroke (HS) treated in the years 1997-1999 at the II Neurology Department, Institute of Psychiatry and Neurology in Warsaw or at the Neurology Department, Hospital in Pila. The analysis of risk factors, fitness before stroke and on the first day of the disease was based on history data. On the first day of the disease the assessment included state of consciousness, brain stem signs, vomiting, stroke type on the basis of clinical condition (according to Oxford classification, OCSP), blood pressure, body temperature measurements, intensity of neurological signs according to Scandinavian scale (SSS). In the blood glucose level, fibrinogen, leucocyte count and ESR were determined. In the first week consciousness state, blood pressure and miction were checked repeatedly. It was found that serious consciousness disturbances, stroke type TACS, POCS and severe not classified stroke, presence of brain stem involvement, low SSS score, high body temperature, high leucocyte count and glucose level were more frequent in patients who died within 30 days after stroke onset. Prognostically important were also instability of blood pressure and urinary incontinence in the first week. All clinical observation and laboratory analyses of prognostic importance in the acute phase of HS can be done in typical hospital settings.
