Abstract
Introduction: Reperfusion therapy (RT) is a mainstay treatment for acute ischemic stroke (AIS). We aimed to evaluate the impact of a comprehensive national policy (CNP) to improve access to RT for AIS patients across Lithuania. Patients and methods: Aggregated anonymized data on AIS cases treated in Lithuanian hospitals between 2006 and 2019 were retrospectively obtained from the Institute of Hygiene and the Stroke Integrated Care Management Committee. Through an interrupted time series analysis, we examined the trends in AIS hospital admissions, RT, and in-hospital case fatality rates prior to the enactment of CNP in 2014, changes immediately after the intervention, and differences in trends between the pre- and post-intervention periods. Mean yearly door-to-needle times were calculated post-intervention. Results: 114,436 cases were treated for AIS in Lithuanian hospitals before, and 65,084 after the government intervention. We observed a significant decreasing post-intervention trend change in AIS hospital admission rate per 100,000 population (regression coefficient ± standard error: β = –16.47 ± 3.95, p = 0.002) and an increasing trend change in the proportion of AIS patients who received reperfusion treatment: intravenous thrombolysis (β = 1.42 ± 0.96, p < 0.001) and endovascular therapy (β = 0.85 ± 0.05, p < 0.001). The proportion of patients treated in stroke centers increased immediately after the intervention (β = 4.95 ± 1.14, p = 0.001), but the long-term post-intervention trend did not change. In addition, there was a significant decreasing trend in all cause in-hospital case fatality rate within primary and comprehensive stroke centers after the intervention (β = –0.60 ± 0.18, p = 0.008) despite its prompt initial immediate increase (β = 1.68 ± 0.73, p = 0.043). The mean countrywide door-to-needle time decreased from 68 min in 2014 to 43 min in 2019. Conclusion: The comprehensive national stroke patient care policy could be associated with an immediate increase in stroke center treatment rate, increased access to RT, and improved stroke care performance measures.

Abstract
Vagus somatosensory evoked potentials (VSEP) and ultrasonography can be used to detect functional and structural changes of the vagus nerve (VN) that are hypothesized to be associated with neurodegenerative diseases. However, it has not yet been established whether age-related changes in the VN occur in the healthy population. In this pilot study we included healthy volunteers in the 26-30 and 51-55 age range who comprised the younger (n = 20) and older (n = 20) groups, respectively. VSEP were recorded separately for stimulation of the auricular branch of the left and right VN. The VN CSA was measured in the transverse plane proximal to the carotid bifurcation, at the level of the distal end of the common carotid artery. No differences were found between the younger and older groups when comparing the average VN CSA (2.01 ± 0.20 vs 2.05 ± 0.20, mm2; p = 0.570) or the CSA of the right (2.08 ± 0.19 vs 2.17 ± 0.24, mm2; p = 0.233) or left VN (1.94 ± 0.26 vs 1.93 ± 0.24, mm2; p = 0.911). The right VN was larger than the left in 95% (n = 19) of older participants and in 65% (n = 13) of younger participants (p = 0.055). In comparison with the younger group, older participants showed significantly longer VSEP latencies of all wave components for electrodes C4-F4 and Fz-F3, of P1 for electrodes C3-F3 and of N1 and P2 for electrodes Fz-F4. The results of this study indicate that older age is associated with longer VSEP latencies but not with changes in VN CSA.

Abstract
BACKGROUND Emotional disturbances, such as anxiety and depression are common after acute ischemic stroke (AIS). Individual variation in emotional outcome is strongly influenced by genetic factors. One of pituitary axis, is the hypothalamic-pituitary-thyroid axis, a critical regulator of post-stroke recovery, suggesting that allelic variants in thyroid hormone (TH) signaling regulation can influence stroke outcome. AIM To determine associations between AIS emotional outcome and allelic variants of the TH metabolizing enzymes 1-3 type deiodinase (DIO1-3) and the membrane transporting organic anion polypeptide 1C1 (OATP1C1). METHODS Eligible AIS patients from Lithuania (n=168) were genotyped for ten DIO1-3 and OATP1C1 single nucleotide polymorphisms (SNP): DIO1 rs12095080-A/G, rs11206244-C/T, and rs2235544-A/C; DIO2 rs225014-T/C and rs225015-G/A; DIO3 rs945006-T/G; OATP1C1 rs974453-G/A, rs10444412-T/C, rs10770704-C/T, and rs1515777-A/G. Emotional outcome was evaluated using the Hospital Anxiety and Depression Scale at discharge from the neurology department after experienced index AIS. RESULTS After adjustment for potential confounders, the major allelic (wild-type) DIO1-rs12095080 genotype (AA) was associated with higher odds ratio of anxiety symptoms (OR = 5.16; 95% CI: 1.04-25.58; p = 0.045), conversely, DIO1-rs11206244 wild-type genotype (CC) and wild-type OATP1C1-rs1515777 allele containing the genotypes (AA + AG) were associated with lower odds ratio of symptoms of anxiety (OR = 0.37; 95% CI: 0.14-0.96; p = 0.041 and OR = 0.30; 95% CI: 0.12-0.76; p = 0.011, respectively). Wild-type OATP1C1-rs974453 genotype (GG) was associated with higher odds ratio of symptoms of depression (OR = 2.73; 95% CI: 1.04-7.12; p = 0.041). CONCLUSION Allelic variants in thyroid axis genes may predict emotional outcomes of AIS.

Abstract
One of the multiple factors believed to contribute to the initiation and maintenance of atrial fibrillation (AF) is altered activity of the autonomic nervous system. Debate continues about the role of the vagus nerve (CNX) in AF since its effect depends on the level of its activation as well as on simultaneous sympathetic activation. Surplus either vagal or sympathetic activity may rarely induce the development of AF; however, typically loss of balance between the both systems mediates the induction and maintenance of AF. Vagal stimulation has been proposed as a novel treatment approach for AF because the anti-arrhythmic effects of low-level vagus nerve stimulation have been shown both in patients and animal models. We hypothesize that in typical cases of AF without any clear trigger by either autonomic nervous system, significant changes in vagus somatosensory evoked potentials and a smaller cross-sectional area of CNX could be detected, representing functional and structural changes in CNX, respectively.

Abstract
BACKGROUND Ischemic stroke is a major cause of premature death and chronic disability worldwide, and individual variation in functional outcome is strongly influenced by genetic factors. Neuroendocrine signaling by the hypothalamic-hypophyseal-thyroid axis is a critical regulator of post-stroke pathogenesis, suggesting that allelic variants in thyroid hormone (TH) signaling can influence stroke outcome. AIM To examine associations between acute ischemic stroke (AIS) outcome and allelic variants of the TH metabolizing enzymes deiodinase type 1-3 (DIO1-3) and membrane transporting organic anion polypeptide C1 (OATP1C1).

Functional outcome was evaluated one year after index AIS using the modified Rankin Scale. Analyses were adjusted for important confounders, including serum free triiodothyronine. RESULTS After adjustment for potential confounders, the major allelic (wild-type) DIO3 genotype rs945006-TT was associated with better 1-year AIS functional outcome (odds ratio [OR] = 0.25; 95% confidence interval [CI]: 0.08-0.74; p = .013), while the wild-type OATP1C1 genotype rs10770704-CC was associated with poorer outcome (OR = 2.00, 95%CI: 1.04-3.86; p = .038). CONCLUSION Allelic variants in thyroid axis genes may prove useful for prognosis and treatment guidance.

Abstract
OBJECTIVE Anxiety and depression symptoms are common after stroke. Changes in thyroid axis hormones have been reported to contribute to these symptoms in clinically euthyroid subjects with and without adjacent somatic pathology. This study aimed to determine associations between serum thyroid axis hormone levels, depression and anxiety symptoms in patients who experienced acute ischemic stroke (AIS). METHODS In total, 169 patients participated in the study. Serum thyroid stimulating hormone, free tetraiodothyronine (FT4) and free triiodothyronine (FT3) levels were assayed on admission and upon discharge from the hospital. Screening for anxiety and depression symptoms was performed with the Hospital Anxiety and Depression Scale twice - while in the hospital and at the end of rehabilitation course. RESULTS In the acute period after AIS, 19.2% of all patients showed symptoms of anxiety and 26.0% - symptoms of depression, while during the subacute period these proportions have increased up to 30.3% and 32.6%. No significant associations between thyroid axis hormones and anxiety were determined for both periods. Serum FT3 levels and FT3/FT4 ratio on admission were significantly lower in patients with symptoms of depression compared to those without. After controlling for possible confounders, lower serum FT3 levels remained significantly associated with higher odds of depression in the acute (OR = 1.85; 95% CI: 1.05-3.23, p = 0.03) and subacute periods (OR = 2.50; 95% CI: 1.06-5.88, p = 0.04) after AIS. CONCLUSIONS FT3 serum levels on admission while in the hospital as well as at the end of rehabilitation course may predict post-stroke depression symptoms.

Abstract
BACKGROUND Results of studies on associations between triiodothyronine serum levels and mortality after acute ischemic stroke (AIS) are inconsistent. Therefore, the aim of this prospective study was to evaluate links between serum levels of thyroid axis associated hormones and all-cause mortality during 1 year after AIS. METHODS AND RESULTS This study involved 255 patients with AIS. Patients were divided into two groups: those who survived 1 year after their index stroke and those who not, and by quartiles of free triiodothyronine (FT3) and ΔFT3 (difference between basal FT3 and repeated FT3 on discharge) hormone serum concentrations. To assess serum levels of thyroid stimulating hormone (TSH), FT3 and free tetraiodothyronine (FT4), venous blood was taken from all included patients on admission to hospital. On discharge, blood tests were repeated for 178 (69.8%) patients. Study endpoints were overall mortality within 30, 90 and 365 days after AIS. RESULTS Compared with the survivals, those who died had significantly lower mean FT3, FT3/FT4 ratio in all periods and lower median TSH within 30 days. Higher FT3 serum levels versus lower, even after adjustment for included important variables, remained significant for lower odds of death within 365 days after AIS (OR=0.57; 95% CI: 0.33-0.97, p=0.04), but added insignificant additional predictive value to the NIHSS score or age. Kaplan-Meier survival curves demonstrated that the first FT3 quartile was significantly associated with increased mortality compared with all other quartiles within 365 days after AIS. With ΔFT3 quartiles no such association was found. CONCLUSIONS Higher FT3 levels on admission versus lower are significantly associated with lower mortality within 365 days after AIS. FT3 serum levels changes over time didn't show any association with mortality within first year.

Abstract
OBJECTIVES Neuromyelitis optica (NMO) is frequently associated with aquaporin-4 autoantibodies (AQP4-Ab); however, studies of NMO in Lithuania are lacking. Therefore, the main objective of our study is to assess positivity for AQP4-Ab in patients presenting with inflammatory demyelinating central nervous system (CNS) diseases other than typical multiple sclerosis (MS) in Lithuania. MATERIALS AND METHODS Data were collected from the two largest University hospitals in Lithuania. During the study period, there were 121 newly diagnosed typical MS cases, which were included in the MS registry database. After excluding these typical MS cases, we analyzed the remaining 29 cases of other CNS inflammatory demyelinating diseases, including atypical MS (n = 14), acute transverse myelitis, TM (n = 8), acute disseminated encephalomyelitis, ADEM (n = 3), clinically isolated syndrome, CIS (n = 2), atypical optic neuritis, ON (n = 1), and NMO (n = 1). We assessed positivity for AQP4-Ab for the 29 patients and evaluated clinical, laboratory, and instrumental differences between AQP4-Ab seropositive and AQP4-Ab seronegative patient groups. RESULTS AQP4-Ab test was positive for three (10.3%) patients in our study, with initial diagnoses of atypical MS (n = 2) and ADEM (n = 1). One study patient was AQP4-Ab negative despite being previously clinically diagnosed with NMO. There were no significant clinical, laboratory, or instrumental differences between the groups of AQP4-Ab positive (3 [10.3%]) and negative (26 [89.7%]) patients. CONCLUSIONS AQP4-Ab test was positive for one-tenth of patients with CNS inflammatory demyelinating diseases other than typical MS in our study. AQP4-Ab testing is highly recommended for patients presenting with not only TM and ON but also an atypical course of MS and ADEM.

Abstract
OBJECTIVES Transcranial ultrasonography (US) is a relatively new neuroimaging modality proposed for early diagnostics of Parkinson disease (PD). The main limitation of transcranial US image-based diagnostics is a high degree of subjectivity caused by low quality of the transcranial images. The article presents a developed image analysis system and evaluates the potential of automated image analysis on transcranial US. METHODS The system consists of algorithms for the segmentation and assessment of informative brain regions (midbrain and substantia nigra) and a decision support subsystem, which is equipped with 64 classification algorithms. Transcranial US images of 191 participants (118 patients with a clinical PD diagnosis and 73 healthy control participants) were analyzed. RESULTS The diagnostic sensitivity and specificity achieved by the proposed system were 85% and 75%, respectively. CONCLUSIONS Digital transcranial US image analysis is challenging, and the application of a such system as the sole instrument for decisions in clinical practice remains inconclusive. However, the proposed system could be used as a supplementary tool for automated assessment of US parameters for decision support in PD diagnostics and to reduce observer variability.

Abstract
BACKGROUND The Eurolight project assessed the impact of headache disorders in ten EU countries, using the same structured questionnaire but varying sampling methods. In Lithuania, sample selection employed methods in line with consensus recommendations for population-based burden-of-headache studies. METHODS The survey was cross-sectional. We identified, from the Residents' Register Service, a sample of inhabitants of Kaunas city and surrounding Kaunas region reflecting age (in the range 18-65 years), gender and rural/urban distributions of Lithuania. Medical students called unannounced at their homes and conducted face-to-face interviews employing a structured questionnaire. RESULTS Of 1137 people in the pre-identified sample, 573 (male 237 [41.4%], female 336 [58.6%]; mean age 40.9 ± 13.8 years) completed interviews (participation proportion: 50.4%). Gender-adjusted 1-year prevalences were: any headache 74.7%; migraine 18.8%; tension-type headache (TTH) 42.2%; all headache on ≥15 days/month 8.6%; probable medication-overuse headache (pMOH) 3.2%. Migraine (OR: 3.6) and pMOH (OR: 2.9) were associated with female gender. All headache types except TTH were associated with significantly diminished quality of life. Migraine caused a mean 4.5% loss in paid worktime per affected male and 3.5% per affected female. Lost per-person times due to TTH were much less, but to pMOH and other headache on ≥15 days/month much higher. Among the entire workforce, lost productivity to migraine was estimated at 0.7%, to TTH 0.3% and to pMOH or other headache on ≥15 days/month 0.5%. The total of 1.5% may translate directly into lost GDP. Alternative calculations based on headache yesterday (with little recall error) produced, for all headache, a corroborating 1.7%. Similar losses from household work would also drain the nation's economy. Our findings were comparable to those from earlier studies using similar methods in Russia and Georgia. CONCLUSIONS The multiple burdens from headache in Lithuania indicate substantial ill-health and unmet need for health care. The heavy burdens on individuals are matched by heavy economic burden. Of particular concern is the high prevalence of headache on ≥15 days/month, seen also in Russia and Georgia. Health policy in Lithuania must heed WHO's advice that effective treatment of headache, clearly desirable for its health benefits, is also expected to be cost-saving.

Abstract
BACKGROUND AND AIM In 2013, all residency programs at the Lithuanian University of Health Sciences were renewed into the competency-based medical education curriculum (CBME). In 2015, we implemented the validated EFFECT questionnaire together with the EFFECT-System for quality assessment of clinical teaching in residency training. The aim of this study was to investigate the influence of characteristics of the resident (year of training) and clinical teacher (gender, age, and type of academic position) on teaching quality, as well as to assess areas for teaching quality improvement. MATERIALS AND METHODS Residents from 7 different residency study programs filled out 333 EFFECT questionnaires evaluating 146 clinical teachers. We received 143 self-evaluations of clinical teachers using the same questionnaire. Items were scored on a 6-point Likert scale. Main outcome measures were residents' mean overall (MOS), mean subdomain (MSS) and clinical teachers' self-evaluation scores. The overall comparisons of MOS and MSS across study groups and subgroups were done using Student's t test and ANOVA for trend. The intraclass correlation coefficient (ICC) was calculated in order to see how residents' evaluations match with self-evaluations for every particular teacher. To indicate areas for quality improvement items were analyzed subtracting their mean score from the respective (sub)domain score. RESULTS MOS for domains of "role modeling", "task allocation", "feedback", "teaching methodology" and "assessment" valued by residents were significantly higher than those valued by teachers (P<0.01). Teachers who filled out self-evaluation questionnaires were rated significantly higher by residents in role modeling subdomains (P<0.05). Male teachers in (sub)domains "role modeling: CanMEDS roles and reflection", "task allocation", "planning" and "personal support" were rated significantly higher than the female teachers (P<0.05). Teachers aged 40 years or younger were rated higher (P<0.01). Residents ratings by type of teachers' academic position almost in all (sub)domains differed significantly (P<0.05). No correlation observed between MOS of a particular teacher and MOS as rated by residents (ICC=0.055, P=0.399). The main areas for improvement were "feedback" and "assessment". CONCLUSIONS Resident evaluations of clinical teachers are influenced by teachers' age, gender, year of residency training, type of teachers' academic position and whether or not a clinical teacher performed self-evaluation. Development of CBME should be focused on the continuous evaluation of quality, clinical teachers educational support and the implementation of e-portfolio.

Abstract
BACKGROUND AND AIM In 2013, all residency programs at the Lithuanian University of Health Sciences were renewed into a competency-based medical education curriculum. To assess the quality of clinical teaching in residency training, we chose the EFFECT (evaluation and feedback for effective clinical teaching) questionnaire designed and validated at the Radboud University Medical Centre in the Netherlands. The aim of this study was to validate the EFFECT questionnaire for quality assessment of clinical teaching in residency training. MATERIALS AND METHODS The research was conducted as an online survey using the questionnaire containing 58 items in 7 domains. The questionnaire was double-translated into Lithuanian. It was sent to 182 residents of 7 residency programs (anesthesiology reanimathology, cardiology, dermatovenerology, emergency medicine, neurology, obstetrics and gynecology, physical medicine and rehabilitation). Overall, 333 questionnaires about 146 clinical teachers were filled in. To determine the item characteristics and internal consistency (Cronbach's α), the item and reliability analyses were performed. Furthermore, confirmatory factor analysis (CFI) was performed using a model for maximum-likelihood estimation. RESULTS Cronbach's α within different domains ranged between 0.91 and 0.97 and was comparable with the original version of the questionnaire. Confirmatory factor analysis demonstrated satisfactory model-fit with CFI of 0.841 and absolute model-fit RMSEA of 0.098. CONCLUSIONS The results suggest that the Lithuanian version of the EFFECT maintains its original validity and may serve as a valid instrument for quality assessment of clinical teaching in competency-based residency training in Lithuania.

Abstract
This paper presents a novel and rapid method developed for semi-automated segmentation of the mid-brain region in B-mode trans-cranial ultrasound (TCS) images. TCS is a relatively new neuroimaging tool having promising application in early diagnosis of Parkinson's disease. The quality of TCS images is much lower compared with the ultrasound images obtained during scanning of the soft tissues; the structures of interest in TCS are difficult to extract and to evaluate. The combination of an experience-based statistical shape model and intensity-amplitude invariant edge detector was proposed for the extraction of fuzzy boundaries of the mid-brain in TCS images. A statistical shape model was constructed using 90 manual delineations of the mid-brain region made by professional neurosonographer. Local phase-based edge detection strategy was applied for determination of plausible mid-brain boundary points used for statistical shape fitting. The proposed method was tested on other 40 clinical TCS images evaluated by two experts. The obtained averaged results of segmentation revealed that the differences between manual and automated measurements are statistically insignificant (p > 0.05).

Abstract
BACKGROUND Essential tremor (ET) and Parkinson's disease (PD) are considered distinct disorders. The aim of the study was to look for a link or any distinguishing features by transcranial sonography (TCS), together with the clinical examination findings in a group of patients with overlapping phenotype of ET and PD (ET-PD). METHODS A prospective observational case-control study was carried out from the 3rd January 2011 until 30th January 2013 at the Hospital of Lithuanian University of Health Sciences. The final study group consisted of 15 patients with ET-PD, 116 patients with ET-only and 141 patients with PD-only. The control group included 101 subjects. Clinical diagnosis was of a diagnostic standard. RESULTS The main ultrasonographic findings in the ET-PD group were similar to those of the PD-only: hyperechogenicity of the substantia nigra (66.7%, p < 0.001) and nuclei raphe interruptions/absence (38.5%, p < 0.001). The single distinguishing TCS finding in ET-PD group was a lentiform nucleus hyperechogenicity (26.7%), however this was only significant when compared to controls (p = 0.006). An asymmetrical onset of symptoms (73.3%) in ET-PD group was characteristic to PD-only. The ET-PD patients had the longest disease duration (median 6 years, p < 0.001), the most frequent rate of positive family history (53.3%, p = 0.005), rather low prevalence of cogwheel rigidity (26.7%, p < 0.001), and higher mean Hoehn & Yahr scores compared to PD-only (2.6 ± 0.8 vs. 1.8 ± 0.8, p = 0.012). CONCLUSIONS The main TCS findings of the present study in patients with overlapping ET-PD phenotype were similar to the PD-only group. The highest positive family history rate among ET-PD patients indicates a strong hereditary predisposition and needs genetic underpinnings. Some ET patients, who look like they may be developing co-morbid PD clinically, may have an alternative diagnosis for Parkinsonism, which could be delineated by TCS examination.

Abstract
BACKGROUND Language dysfunction in children with benign epilepsy with centrotemporal spikes (BECTS) has been well recognized but data regarding its risk factors are heterogenous. AIMS To assess language function in children with BECTS and its association with the age of epilepsy onset. METHODS We assessed language function in 61 children with BECTS and 35 age and sex-matched controls. Children with BECTS performed significantly worse on all language tasks as compared to controls and overall better language function was positively correlated with older age of the child. Early age at seizure onset demonstrated significant negative correlation with language dysfunction, age below 6 years being related to the lowest performance scores. There was no relationship between the language function and the laterality of epileptic focus, seizure treatment status, or the duration of epilepsy. CONCLUSION Children with BECTS have language difficulties that are more pronounced in younger age group. Despite better language functioning in older children with BECTS, their verbal abilities remain inferior to those of children without epilepsy. Early age at seizure onset is a significant factor predicting worse language functioning in children with BECTS.

Abstract
Background Hyperechogenicity of the substantia nigra (SN+), detected by transcranial sonography (TCS), was reported as a characteristic finding in Parkinson's disease (PD), with high diagnostic accuracy values, when compared mainly to healthy controls or essential tremor (ET) group. However, some data is accumulating that the SN + could be detected in other neurodegenerative and even in non-neurodegenerative disorders too. Our aim was to estimate the diagnostic accuracy of TCS, mainly focusing on the specificity point, when applied to a range of the parkinsonian disorders, and comparing to the degenerative cognitive syndromes. Methods A prospective study was carried out at the Hospital of Lithuanian University of Health Sciences from January until September 2011. Initially, a TCS and clinical examination were performed on 258 patients and 76 controls. The General Electric Voluson 730 Expert ultrasound system was used. There were 12.8% of cases excluded with insufficient temporal bones, and 4.3% excluded with an unclear diagnosis. The studied sample consisted of the groups: PD (n = 71, 33.2%), ET (n = 58, 27.1%), PD and ET (n = 10, 4.7%), atypical parkinsonian syndromes (APS) (n = 3, 1.4%), hereditary neurodegenerative parkinsonism (HDP) (n = 3, 1.4%), secondary parkinsonism (SP) (n = 23, 10.8%), mild cognitive impairment (MCI) (n = 33, 15.4%), dementia (n = 13, 6.1%), and control (n = 71). Results There were 80.3% of PD patients at stages 1 & 2 according to Hoehn and Yahr. At the cut-off value of 0.20 cm2 of the SN+, the sensitivity for PD was 94.3% and the specificity - 63.3% (ROC analysis, AUC 0.891), in comparison to the rest of the cohort. At the cut-off value of 0.26 cm2, the sensitivity was 90% and the specificity 82.4%. The estimations for the lowest specificity for PD, in comparison to the latter subgroups (at the cut-off values of 0.20 cm2 and 0.26 cm2, respectively) were: 0% and 33.3% to APS, 33.3% and 66.7% to HDP, 34.8% and 69.6% to SP, 55.2% and 82.8% to ET, 75% and 91.7% to dementia. Conclusions The high sensitivity of the test could be employed as a valuable screening tool. But TCS is more useful as a supplementary diagnostic method, due to the specificity values not being comprehensive.

Abstract
The aim of the present study was to investigate the influence of HLA-DRB1 alleles on the genetic susceptibility to multiple sclerosis in the Lithuanian population. MATERIAL AND METHODS. A total of 120 patients with multiple sclerosis and 120 unrelated healthy controls were enrolled in this case-control study. Allelic frequencies were compared between the groups. HLA-DRB1 alleles were genotyped using the polymerase chain reaction. RESULTS. HLA-DRB1*15 was present in 55.8% of the patients with multiple sclerosis and 10.0% of the controls (OR, 5.58; 95% CI, 3.19-9.77; P<0.0001). The protective alleles that were found to be more prevalent among the controls compared with the patients with multiple sclerosis were HLA-DRB1*01 (26.7% vs. 7.5%, P<0.0001), *03 (17.5% vs. 8.3%, P=0.034), and *16 (11.7% vs. 3.3%, P=0.014). HLA-DRB1*15 was more common among the female patients with multiple sclerosis than among the male patients (68.4% vs. 34.1%; OR, 4.18; 95%, CI 1.90-9.22; P=0.001). The heterozygous inheritance of HLA-DRB1*15 allele was more common in the patients with a history of maternal multiple sclerosis than in those with a history of paternal multiple sclerosis (29.4% vs. 9.8%; P=0.045). CONCLUSIONS. HLA-DRB1*15 was found to be associated with multiple sclerosis in the Lithuanian population. This allele was more prevalent among the female patients with multiple sclerosis. Maternal multiple sclerosis was more common than paternal multiple sclerosis, but the relationship with HLA-DRB1*15 allele was not established. HLA-DRB1*01, *03, and *16 appeared to be the protective alleles in this series.

Abstract
UNLABELLED The aim of this study was to evaluate the recovery of functional status and effectiveness of the second-stage rehabilitation depending on the degree of cognitive impairment in stroke patients. MATERIAL AND METHODS The study sample comprised 226 stroke patients at the Viršužiglis Hospital of rehabilitation, Hospital of Lithuanian University of Health Sciences. Functional status was evaluated with the Functional Independence Measure, cognitive function with the Mini-Mental Status Examination scale, and severity of neurologic condition with the National Institutes of Health Stroke Scale. The patients were divided into 4 study groups based on cognitive impairment: severe, moderate, mild, or no impairment. RESULTS More than half (53%) of all cases were found to have cognitive impairment, while patients with different degree of cognitive impairment were equally distributed: mild impairment (18%), moderate impairment (17%), and severe impairment (18%). Improvement of functional status was observed in all study groups (P<0.001). In the patients with moderate and severe cognitive impairment, cognitive recovery was significantly more expressed than in other study groups (P<0.001). Insufficient recovery of functional status was significantly associated with hemiplegia (OR, 11.15; P=0.015), urinary incontinence (OR, 14.91; P<0.001), joint diseases (OR, 5.52; P=0.022), heart diseases (OR, 4.10; P=0.041), and severe cognitive impairment (OR, 15.18; P<0.001), while moderate and mild cognitive impairment was not associated with the recovery of functional status. CONCLUSIONS During the second-stage rehabilitation of stroke patients, functional status as well as cognitive and motor skills were improved both in patients with and without cognitive impairment; however, the patients who were diagnosed with severe or moderate cognitive impairment at the beginning of second-stage rehabilitation showed worse neurological and functional status during the whole second-stage rehabilitation than the patients with mild or no cognitive impairment.

Abstract
OBJECTIVE The aim of this study was to determine the sensitivity and specificity of this classical technique employed at the Hospital of Lithuanian University of Health Sciences for the patients with multiple sclerosis and to assess its possible correlations with affected neurological systems. MATERIAL AND METHODS Pattern shift visual evoked potentials were recorded in 63 patients with multiple sclerosis, 17 (27%) of whom had a history of optic neuritis, and in 63 control patients with other neurological diseases. The latencies and amplitudes of P100 were measured. In total, 126 patients were referred to the inpatient department of neurology for differential diagnosis of demyelinating disorders between January and December of 2007. RESULTS Abnormalities of visual evoked potentials were observed by 73% more frequently in patients with multiple sclerosis than in control patients (α=0.05, β<0.01). The combined monocular/interocular test showed a specificity of 90.5% and a sensitivity of 82.5%. The probability of an affection of the pyramidal system was 5 times greater (95% CI, 2.2-11.0; P<0.01) and the probability of the optic pathways involvement was 4.8 times greater (95% CI, 1.9-11.9; P<0.01) in patients with multiple sclerosis than in controls. CONCLUSION Conventional visual evoked potentials must be reappraised in light of their diagnostic value in multiple sclerosis given their high diagnostic efficiency, relatively easy, short, and cheap implementation, and easy availability in everyday clinical practice.

Abstract
UNLABELLED The aim of the study was to evaluate patients' satisfaction with the quality of provided services in private primary health care institutions in Kaunas. MATERIAL AND METHODS A questionnaire-based inquiry of 280 persons registered to family physicians at primary health care settings was performed. The study was carried out using 20-item anonymous questionnaires with questions about the quality of services provided in primary health care settings. RESULTS More than 50.0% of the respondents stated that they waited for more than 15 minutes at the physician's office, while 17.0% of the respondents stated that the waiting time exceeded 30 minutes. More than 25.0% of the respondents positively evaluated the possibility to consult their family physician by phone. In 67.0% of patients, the family physician determined the cause of the disorder and administered treatment; in 32.0% of patients, the family physician referred them to a specialist, and 1.0% of patients were urgently sent to hospital. More than 90.0% of the respondents were satisfied with the services provided by their family physicians. Those who were dissatisfied with these services indicated that the provided treatment failed to eliminate the disorder, that they wanted to be referred to a specialist, and that they expected more diagnostic tests to be performed for more effective treatment. CONCLUSIONS A greater part of the patients indicated that the main reason for long waiting at the physician's office was physicians' wish to serve too many patients. More than two-thirds (67.0%) of the patients stated that their family physicians determined the cause of the disorder and prescribed treatment. The overwhelming majority (more than 90.0%) of the patients were satisfied with the services provided by their family physicians.

Abstract
UNLABELLED The aim of the present study was to determine the value of immunogenetic risk factors and to estimate their relationship with the clinical features and disability status of patients with multiple sclerosis in a Lithuanian population. MATERIALS AND METHODS This was a prospective study of 80 patients with multiple sclerosis. The diagnosis of multiple sclerosis was based on the revised McDonald criteria. Oligoclonal bands (OCBs) of immunoglobulin G (IgG) were tested using isoelectric focusing and IgG specific immunofixation. HLA DRB1 alleles were genotyped using polymerase chain reaction. RESULTS Of all patients, 55% were positive for OCBs and 56% for HLA DRB1*1501. OCB-positive patients with multiple sclerosis had higher EDSS scores than their OCB-negative counterparts at onset of the disease (3.93±1.21 and 3.36±0.96 points, respectively; P=0.02) and during the last visit (4.31±2.06 and 3.09±1.98 points, respectively; P=0.009). The mean relapse rate was higher in the OCB-positive group compared with OCB-negative group (1.45±0.69 and 0.58±0.64, respectively; P=0.001). OCB-positive patients had higher IgG index compared with OCB-negative patients (P=0.0001). No relationship was found between HLA DRB1*1501 antigen status and the clinical features or EDSS score, and presence or absence of OCB in the present subset of patients with multiple sclerosis. CONCLUSIONS The presence of oligoclonal bands in the cerebrospinal fluid of the patients with multiple sclerosis was associated with the greater number of exacerbations, higher degree of disability, and higher IgG index. There were no significant associations between the presence of HLA DRB1*1501 allele and the clinical symptoms, course of disease, or disability score.

Abstract
UNLABELLED The aim of the study was to determine the associations between the quality of life and social and demographic factors in stroke survivors and control group. MATERIAL AND METHODS The case group consisted of 508 inhabitants of Kaunas city who were aged 25-84 years and had survived a stroke. The control group included 508 age- and sex-matched inhabitants of Kaunas city randomly selected from the stroke-free population. The SF-12 questionnaire was used in the study. Quality of life in the physical and mental health domains with respect to social and demographic factors was analyzed. RESULTS A significant inverse correlation was found between the evaluation of physical health and age in both the stroke survivors and controls (r=-0.34, P<0.05, and r=-0.64, P<0.05, respectively). The comparison of the evaluation of physical health between men and women showed that only in the control group, men demonstrated significantly better physical health than women (P=0.0005), while no statistically significant difference in this respect was found comparing male and female stroke survivors. Stroke survivors of Lithuanian nationality reported better physical health as compared to individuals of other nationalities (P=0.008). Both the controls (P=0.01) and stroke survivors (P=0.008) who were not living alone scored higher on the physical health domain than their counterparts living alone. Employed subjects - both the controls and stroke survivors - presented better evaluations of their physical health (P=0.005 in both the groups). CONCLUSIONS Quality of life in the physical health domain worsened with age both in the stroke survivors and controls. Both in the stroke survivors and controls, males and females with higher education levels, not living alone, and having employment demonstrated better evaluations of their quality of life in the physical health domain compared to those with poorer education, living alone, or unemployed.
