Background: The COVID-19 pandemic raised concern amongst clinicians that disease-modifying therapies (DMT), particularly anti-CD20 monoclonal antibodies (mAb) and fingolimod, could worsen COVID-19 in people with multiple sclerosis (pwMS). This study aimed to examine DMT prescribing trends pre- and post-pandemic onset., Methods: A multi-centre longitudinal study with 8,771 participants from MSBase was conducted. Two time periods were defined: pre-pandemic (March 11 2018-March 10 2020) and post-pandemic onset (March 11 2020-11 March 2022). The association between time and prescribing trends was analysed using multivariable mixed-effects logistic regression. DMT initiation refers to first initiation of any DMT, whilst DMT switches indicate changing regimen within 6 months of last use., Results: Post-pandemic onset, there was a significant increase in DMT initiation/switching to natalizumab and cladribine [(Natalizumab-initiation: OR 1.72, 95% CI 1.39-2.13; switching: OR 1.66, 95% CI 1.40-1.98), (Cladribine-initiation: OR 1.43, 95% CI 1.09-1.87; switching: OR 1.67, 95% CI 1.41-1.98)]. Anti-CD20mAb initiation/switching decreased in the year of the pandemic, but recovered in the second year, such that overall odds increased slightly post-pandemic (initiation: OR 1.26, 95% CI 1.06-1.49; Switching: OR 1.15, 95% CI 1.02-1.29. Initiation/switching of fingolimod, interferon-beta, and alemtuzumab significantly decreased [(Fingolimod-initiation: OR 0.55, 95% CI 0.41-0.73; switching: OR 0.49, 95% CI 0.41-0.58), (Interferon-gamma-initiation: OR 0.48, 95% CI 0.41-0.57; switching: OR 0.78, 95% CI 0.62-0.99), (Alemtuzumab-initiation: OR 0.27, 95% CI 0.15-0.48; switching: OR 0.27, 95% CI 0.17-0.44)]., Conclusions: Post-pandemic onset, clinicians preferentially prescribed natalizumab and cladribine over anti-CD20 mAbs and fingolimod, likely to preserve efficacy but reduce perceived immunosuppressive risks. This could have implications for disease progression in pwMS. Our findings highlight the significance of equitable DMT access globally, and the importance of evidence-based decision-making in global health challenges., (© 2024. The Author(s).)

Multiple sclerosis (MS) is an inflammatory autoimmune disorder of the central nervous system and the leading cause of progressive neurological disability in young adults. It decreases the patient's lifespan by about 10 years and affects women more than men. No medication entirely restricts or reverses neurological degradation. However, early diagnosis and treatment increase the possibility of a better outcome. To identify new MS biomarkers, we tested the expression of six potential markers (P2X4, P2X7, CXCR4, RGS1, RGS16 and VAV1) using qPCR in peripheral blood mononuclear cells (PBMC) of MS patients treated with interferon β (IFNβ), with glatiramer acetate (GA) or untreated. We showed that P2X7 and VAV1 are significantly induced in MS patients. In contrast, the expression of P2X4, CXCR4, RGS1 and RGS16 was not significantly modified by MS in PBMC. P2X7 and VAV1 are essentially induced in female patients, suggesting these markers are connected to sex-specific mechanisms. Strikingly, VAV1 expression is higher in healthy women than healthy men and IFNβ treatment of MS reduced VAV1 expression in female MS patients while it up-regulated VAV1 in male MS patients. Our data point to the differential, sex-dependent value of MS markers and treatment effects. Although rgs16 expression in PBMC was not a valid MS marker in patients, the strong upregulation of P2X4 and P2X7 induced in the spinal cord of WT mice by EAE was abrogated in rgs16KO mice suggesting that rgs16 is required for P2X4 and P2X7 induction by neurological diseases., (© 2023 The Scandinavian Foundation for Immunology.)

Background: Monitoring and measuring different aspects of stroke care pathway is the cornerstone for improvement of quality. We aim to analyze and give an overview of improvements of stroke care quality in Estonia., Patients and Methods: National stroke care quality indicators are collected and reported using reimbursement data and include all adult stroke cases. In Estonia, five stroke-ready hospitals are participating in Registry of Stroke Care Quality (RES-Q), providing data on all stroke patients 1 month every year. Data from the national quality indicators and RES-Q from 2015 to 2021 are presented., Results: The proportion of intravenous thrombolysis for all Estonian hospitalized ischemic stroke cases increased from 16% (95% Confidence Interval, CI 15%-18%) in 2015 to 28% (95% CI 27%-30%) in 2021. Mechanical thrombectomy was provided to 9% (95% CI 8%-10%) in 2021. The 30-day mortality rate has decreased from 21% (95% CI 20%-23%) to 19% (95% CI 18%-20%). More than 90% of patients with cardioembolic stroke are prescribed anticoagulants at discharge, but only 50% are on anticoagulant treatment 1 year after stroke. Also, the availability of inpatient rehabilitation needs improvement, being 21% (95% CI 20%-23%) in 2021. A total of 848 patients are included in the RES-Q. The proportion of patients receiving recanalization therapies was comparable to the national stroke care quality indicators. All stroke-ready hospitals show good onset-to-door times., Conclusion: The overall stroke care quality in Estonia is good, especially the availability of recanalization treatments. However, secondary prevention and the availability of rehabilitation services need improvement in the future., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© European Stroke Organisation 2022.)

Ischemic stroke is defined as neurological deficit caused by brain infarction. The intravenous tissue plasminogen activator, alteplase, is an effective treatment. However, efficacy of this method is time dependent. An important step in improving outcome and increasing the number of patients receiving alteplase is the shortening of waiting times at the hospital, the so-called door-to-needle time (DNT). The comprehensive Helsinki model was proposed in 2012, which enabled the shortening of the DNT to less than 20 min. Background and Objectives : The aim of this study was to analyze the transferability of the suggested model to the West Tallinn Central Hospital (WTCH). Materials and Methods : Since the first thrombolysis in 2005, all patients are registered in the WTCH thrombolysis registry. Several steps following the Helsinki model have been implemented over the years. Results : The results demonstrate that the number and also the percent of thrombolysed stroke patients increased during the years, from a few thrombolysis annually, to 260 in 2021. The mean DNT dropped significantly to 33 min after the implementation of several steps, from the emergency medical services (EMS) prenotification with a phone call to the neurologists, to the setting-up of a thrombolysis team based in the stroke unit. Also, the immediate start of treatment using a computed tomography table was introduced. Conclusions : In conclusion, several implemented steps enabled the shortening of the DNT from 30 to 25.2 min. Short DNTs were achieved and maintained only with EMS prenotification.

Background: Ofatumumab, the first fully human anti-CD20 monoclonal antibody, is approved in several countries for relapsing multiple sclerosis (RMS)., Objective: To demonstrate the bioequivalence of ofatumumab administered by an autoinjector versus a pre-filled syringe (PFS) and to explore the effect of ofatumumab on B-cell depletion., Methods: APLIOS (NCT03560739) is a 12-week, open-label, parallel-group, phase-2 study in patients with RMS receiving subcutaneous ofatumumab 20 mg every 4 weeks (q4w) (from Week 4, after initial doses on Days 1, 7, and 14). Patients were randomized 10:10:1:1 to autoinjector or PFS in the abdomen, or autoinjector or PFS in the thigh, respectively. Bioequivalence was determined by area under the curve (AUC τ ) and maximum plasma concentration ( C max ) for Weeks 8-12. B-cell depletion and safety/tolerability were assessed., Results: A total of 256 patients contributed to the bioequivalence analyses (autoinjector-abdomen, n = 128; PFS-abdomen, n = 128). Abdominal ofatumumab pharmacokinetic exposure was bioequivalent for autoinjector and PFS (geometric mean AUC τ , 487.7 vs 474.1 h × µg/mL (ratio 1.03); C max , 1.409 vs 1.409 µg/mL (ratio 1.00)). B-cell counts (median cells/µL) depleted rapidly in all groups from 214.0 (baseline) to 2.0 (Day 14). Ofatumumab was well tolerated., Conclusion: Ofatumumab 20 mg q4w self-administered subcutaneously via autoinjector is bioequivalent to PFS administration and provides rapid B-cell depletion.

Background: Rare diseases are an important population health issue and many promising therapies have been developed in recent years. In light of novel genetic treatments expected to significantly improve spinal muscular atrophy (SMA) patients' quality of life and the urgent need for SMA newborn screening (NBS), new epidemiological data were needed to implement SMA NBS in Estonia. Objective: We aimed to describe the birth prevalence of SMA in the years 1996-2020 and to compare the results with previously published data. Methods: We retrospectively analyzed clinical and laboratory data of SMA patients referred to the Department of Clinical Genetics of Tartu University Hospital and its branch in Tallinn. Results: Fifty-seven patients were molecularly diagnosed with SMA. SMA birth prevalence was 1 per 8,286 (95% CI 1 per 6,130-11,494) in Estonia. Patients were classified as SMA type 0 (1.8%), SMA I (43.9%), SMA II (22.8%), SMA III (29.8%), and SMA IV (1.8%). Two patients were compound heterozygotes with an SMN1 deletion in trans with a novel single nucleotide variant NM_000344.3:c.410dup, p.(Asn137Lysfs*11). SMN2 copy number was assessed in 51 patients. Conclusion: In Estonia, the birth prevalence of SMA is similar to the median birth prevalence in Europe. This study gathered valuable information on the current epidemiology of SMA, which can guide the implementation of spinal muscular atrophy to the newborn screening program in Estonia., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Sarv, Kahre, Vaidla, Pajusalu, Muru, Põder, Gross-Paju, Ütt, Žordania, Talvik, Õiglane-Shlik, Muhu and Õunap.)

Secondary progressive multiple sclerosis (SPMS) is a debilitating condition characterized by gradual worsening after an initial relapsing disease course. Despite the recent advances in our understanding of the disease, the diagnosis and treatment of SPMS continue to be challenging in routine clinical practice. The aim of this review article is to present the views of leading MS experts on the challenges in the diagnosis and management of SPMS and clinicians' perspectives in Central and Eastern Europe. This article also provides recommendations of MS experts to improve the situation with diagnosis and management of SPMS. Many countries within Central and Eastern Europe have high prevalence of MS (>100 per 100,000 population). Consistent with the global trend, in the absence of reliable tests or biomarkers, SPMS at early stage remains undiagnosed. Due to diagnostic uncertainty and lack of a universally accepted disease definition, clinicians rely more on retrospective analysis of the clinical symptoms to confirm the diagnosis. With the lack of awareness and poor understanding of the timing of the onset of SPMS, clinicians may tend to direct attention to relapses than the symptoms of progression, which leads to underestimation of SPMS. Although several predictors of progression to SPMS have been identified, their predictive value is highly variable. Therefore, defining the transitioning period as a separate stage of MS is essential. According to experts' opinion, frequent follow-up of patients and periodic assessment of progression are recommended for the timely identification of patients transitioning from RRMS to SPMS. MSProDiscuss Tool is an example of a quick assessment tool for identifying patients progressing from RRMS to SPMS. MS progression is usually assessed by changes in Expanded Disability Status Scale (EDSS) scores. As EDSS scores tend to fluctuate when measured in the short term (3-6 months), a longer period (≥12 months) may be needed to confirm the progression. Assessment of cognitive function is also important for evaluating secondary progression. Compartmentalization of inflammation within the central nervous system is an important reason behind the limited success of disease-modifying therapies (DMTs) for treating SPMS. Most of the DMTs fail to cross the blood-brain barrier; only 38% of the tested DMTs achieved their primary endpoint in SPMS. In Europe, siponimod is the first oral treatment for adults with active SPMS. Particularly, in Central and Eastern Europe, patients with SPMS are still being prescribed less efficacious DMTs and interferons. The absence of alternative treatments in SPMS supports the use of new products (siponimod and others); however the decision to initiate siponimod therapy in more severe patients (EDSS score of 7 or higher) should be individualized in consultation with the payers. The focus should be on early treatment initiation to delay disease progression., (Copyright © 2021 Elsevier B.V. All rights reserved.)

Multiple sclerosis (MS) is mediated primarily by autoreactive T cells. However, evidence suggesting the involvement of humoral immunity in brain diseases has increased interest in the role of B cells and their products during MS pathogenesis. The major survival factor for B cells, BAFF has been shown to play a role in several autoimmune conditions. Elevated BAFF levels have been reported in MS animal model and during MS relapse in patients. Moreover, disease-modifying treatments (DMT) reportedly influence blood BAFF levels in MS patients, but the significance of these changes remains unclear. The present study addresses how blood BAFF levels are associated with the clinical course of relapsing-remitting MS and the effectiveness of DMT and short-term steroid treatment. During a prospective longitudinal follow-up of 2.3 years, BAFF was measured in the blood of 170 MS patients in the stable phase and within 186 relapses. BAFF levels were significantly higher in MS patients compared to healthy controls. However, stable MS patients without relapses exhibited significantly higher BAFF levels than relapsing patients. Treatment with interferon-β and immunosuppressants raised BAFF blood levels. Interestingly, a similar effect was not seen in patients treated with glatiramer acetate. Short-term treatment with high doses of intravenous methylprednisolone did not significantly alter plasma BAFF levels in 65% of relapsing-remitting MS patients. BAFF were correlated weakly but significantly with monocyte and basophil counts, but not with other blood cell types (neutrophils, lymphocytes, or eosinophils) or inflammatory biomarkers. To our knowledge, this is the first report demonstrating that higher blood BAFF levels may reflect a more stable and effective MS treatment outcome. These results challenge hypotheses suggesting that elevated blood BAFF levels are associated with more severe disease presentation and could explain the recent failure of pharmaceutical trials targeting BAFF with soluble receptor for MS treatment.

A clinical case of encephalitis caused by antibodies to NMDA-receptors is presented. This rare pathology is characterized by severe cognitive impairment and needs careful differential diagnosis.

Background: Purpose of the study was to investigate alterations in midbrain serotonin transporter (SERT) binding in patients with epilepsy and symptoms of depression compared to patients with epilepsy with no symptoms of depression., Methods: We studied 12 patients with epilepsy (7 patients had focal and 5 had generalized epilepsy syndromes). The presence of self-reported symptoms of depression was assessed using Beck Depression Inventory (BDI) and the Emotional State Questionnaire (EST-Q). The binding potential of the SERT was assessed by performing brain single photon emission tomography (SPET) using the SERT radioligand 2-((2-((dimethylamino)methyl)phenyl)thio)-5-(123)iodophenylamine (123I-ADAM)., Results: Seven patients had BDI and EST-Q subscale scores greater than 11 points, which was interpreted as the presence of symptoms of depression. We found that 123I-ADAM binding was not significantly different between patients with epilepsy with and without symptoms of depression. In addition, 123I-ADAM binding did not show a significant correlation to either BDI or EST-Q depression subscale scores and did not differ between patients with focal vs. generalized epilepsy., Conclusion: The results of our study failed to demonstrate alterations of SERT binding properties in patients with epilepsy with or without symptoms of depression.

Background and Objective: The aim of the present study was to describe the cognitive profile of patients with focal and generalized epilepsy syndrome in comparison with healthy control subjects and to investigate whether depression was related to neuropsychological functioning in these patients., Material and Methods: A total of 36 patients with focal epilepsy and 26 patients with generalized epilepsy were compared with the control group of healthy volunteers (n=53). A battery of neuropsychological tests assessing verbal and visual spatial memory and executive functioning was carried out in addition to the completion of the Beck Depression Inventory (BDI)., Results: The results indicated that patients with epilepsy performed significantly worse than controls on all verbal memory subscales and verbal fluency domains. The patients with focal epilepsy scored significantly worse than the patients with generalized epilepsy. The BDI scores were significantly correlated with several scores of the cognitive test in both patients' groups but not in the control group., Conclusions: Our results suggest that patients with epilepsy, especially with focal-onset epilepsy, show cognitive disturbances predominantly in the verbal memory domain. In addition, depression was found to have a negative effect on cognitive functioning in patients with epilepsy.

Study Design: Observational population-based cohort study., Objectives: The main aim of this study was to examine the relative effect of hereditary spastic paraplegia (HSP) on the health-related quality of life (HRQoL)., Methods: HRQoL was evaluated using a RAND 36-Item Health Survey 1.0 questionnaire. Fifty-eight patients received a questionnaire through mail and signed an informed consent. The results for the control group were obtained from the RAND-36 data collected in 2004 in the European Social Survey. R2.9.0 and Statistica 6.1 were used to analyze the RAND-36 data., Setting: The study was performed in Estonia, a country with a population of 1.3 million., Results: Completed questionnaires were received from 49 participants (response rate was 84.5%). The control group consisted of 549 individuals from the Estonian population. Patients with HSP had lower mean scores in all categories as compared with the control group. Six of the eight categories showed significant differences, with P<0.0001. For the vitality category, the P-value ranged from 0.000006 from 0.002, and the P-value for the mental health category ranged from 0.001 to 0.055., Conclusions: The HRQoL in patients with HSP was found to be significantly worse than that for the general population. The level of education might affect the HRQoL experienced by HSP patients.

The aim of this report is to present the first four cases from three families of dopa-responsive dystonia diagnosed in Estonia. Diagnosis was performed by clinical evaluation and response to levodopa and was confirmed by gene analyses. The prevalence of dopa-responsive dystonia in Estonia was 1.4 per 100,000 (95%CI=0.39-3.65) children less than 18 years of age. In all children with dystonia it is important to think about possible dopa-responsive dystonia as this is treatable condition and improving the quality of life of children., (Copyright 2009 Elsevier B.V.

Background: Hereditary spastic paraplegia (HSP) is a clinically and genetically heterogeneous disorder that can be an autosomal-dominant, autosomal-recessive, or X-linked disease. The most common autosomal-dominant form of the disease derives from mutations in the SPAST gene., Methods: The aim of this study was to analyze 49 patients diagnosed with HSP from the Estonian population for sequence variants of the SPAST gene and to describe the associated phenotypes. Healthy control individuals (n = 100) with no family history of HSP were also analyzed. All patient samples were screened using denaturing high performance liquid chromatography (DHPLC) and multiplex ligation-dependent probe amplification (MLPA) assay. Samples with abnormal DHPLC and MLPA profiles were sequenced, with the same regions sequenced in control samples., Results: Sequence variants of SPAST were identified in 19/49 HSP patients (38.8%), twelve among them had pathogenic mutations. Within the latter group there was one sporadic case. Eight patients had pure, and four - complex HSP. The twelve variants were identified: seven pathogenic (c.1174-1G>C, c.1185delA, c.1276C>T, c.1352&#95;1356delGAGAA, c.1378C>A, c.1518&#95;1519insTC, c.1841&#95;1842insA) and five non-pathogenic (c.131C>T, c.484G>A, c.685A>G, c.1245+202delG, c.1245+215G>C). Only 2 of these mutations had previously been described (c.131C>T, c.1245+202delG). Three mutations, c.1174-1G>C, c.1276 C>T, c.1378C>A, showed intrafamilial segregation., Conclusion: This study identified new variants of the SPAST gene which included benign missense variants and short insertions/deletions. No large rearrangements were found. Based on these data, 7 new pathogenic variants of HSP are associated with clinical phenotypes.

Background: Hereditary spastic paraplegia (HSP) comprises a group of rare neurodegenerative disorders characterised by progressive spasticity and hyperreflexia of the legs. Neurogenic bladder dysfunction is a well recognised problem in patients with HSP but it has not yet been described systematically in the literature. The aim of this study was to provide an evidential overview of the ways in which urinary dysfunction presents in HSP., Methods: 49 patients with HSP were included and underwent evaluation. A history was followed by a semi-structured interview and, in those patients who consented, measurement of residual volume of urine (PVR) and urodynamic evaluation., Results: 38 subjects (77.6%) reported some type of urinary symptom. Subjective complaints of bladder problems showed a correlation with verified urinary dysfunction. There were no significant differences in the occurrence of urinary disturbances between the pure and complex forms of HSP. The most frequent symptoms were incontinence (69.4%), hesitancy (59.2%), increased frequency of micturition (55.1%) and urgency (51.0%). Incomplete bladder emptying was the rarest (36.7%). The most common combination of symptoms was to have all of them (14.3%). Incomplete bladder emptying as a complaint was associated with an increased risk of PVR. Women had a higher risk of increased voiding frequency., Conclusions: To our knowledge, this work is the first systematic and disease oriented overview of neurogenic bladder disturbances in patients with HSP. Our results may be useful to the clinicians who work with HSP patients, allowing them to make appropriate screening and management decisions.

Objectives: To characterize the spasticity and range of motion (ROM) in patients with hereditary spastic paraplegia (HSP) and to correlate these parameters with walking speed., Design: An observational population-based cohort study., Setting: Patient data were acquired from a population-based epidemiologic study performed earlier in Estonia., Participants: Persons (N=46) (mean age, 50.1y) with clinically confirmed HSP diagnosis (mean duration, 20.9y) participated in the study., Interventions: Active and passive ROMs were measured with a plastic 360 degrees goniometer. Spasticity was evaluated by using the modified Ashworth scale (MAS). The time it took a patient to walk 10m was recorded., Main Outcome Measures: Measurements included testing of active and passive ROM as a marker for mobility, the MAS for spasticity, and time to complete a 10-m walk., Results: A higher degree of spasticity in hip muscles was associated with lower values of active ROM and slower walking. Walking speed was negatively correlated to disease duration and participant age., Conclusions: The present study provides analysis of the contributions of spasticity and ROM to walking speed in HSP, both factors negatively influence gait in persons with HSP.

Objective: To evaluate the prevalence of depression and sensitivity and specificity of the single-item interview 'Are you depressed?' for people with hereditary spastic paraplegia in Estonia., Design: Single-item interview 'Are you depressed?' was used as a screening question for depression; all participants then completed the Beck Depression Inventory., Setting: People with hereditary spastic paraplegia identified from the epidemiological database who agreed to participate in the study., Main Measures: Beck Depression Inventory, clinical interview., Results: The epidemiological database consisted of 59 patients with clinically confirmed diagnosis of hereditary spastic paraplegia. Forty-eight of these consented to participate in the study. The Beck Depression Inventory score was higher than cut-off point in 58% (28/48) and lower in 42% (20/48). Of the study group, 44% (21/48) had mild, 13% (6/48) moderate and one person revealed severe depression. There was a statistically significant correlation between Beck Depression Inventory score and level of mobility; no other significant correlations with other measures were detected. Of the participants, 54% (26/48) had subjective complaints about depression and answered 'Yes' to the single-item interview 'Are you depressed?'. The sensitivity of the one-item interview in the hereditary spastic paraplegia group was 75% and specificity 75%., Conclusions: Our results show that mild depression is prevalent among people with hereditary spastic paraplegia. Although the single question may be helpful, it cannot be relied upon entirely when assessing a person for depression.

The aim of the study was to compare subjective complaints of epilepsy patients with objective results of neuropsychological assessment and to investigate the possible influence of depression on self-reported complaints. 62 patients from the neurology clinic were included in the study. They were asked to fill the subjective complaints questionnaire, Beck Depression Inventory and a series of neuropsychological tests. The results indicated that self-reported cognitive complaints are not strongly associated with objective tests of different cognitive performance measures. We conclude that the discrepancy between subjective and objective cognitive functioning does not only affect the area of memory but a wide range of cognitive domains. Depression is an important factor influencing the level of different subjective complaints.

Background: Bladder problems are very common in persons with multiple sclerosis (PwMS)., Objective: The aim of this study was to investigate the ability of PwMS to learn clean intermittent self-catheterization (CISC)., Methods: The physical disability of 23 PwMS was evaluated with the Expanded Disability Status Scale (EDSS), and cognitive status was evaluated with the Brief Repeatable Battery of Neuropsychological Tests (BRB-N). CISC was taught by the same continence advisor who was blinded to the cognitive test results. The ability to learn CISC was evaluated immediately after sessions and 3 months later. Twenty-three consecutive PwMS participated in the study., Results: In all, 87% (20/23) of the PwMS successfully finished CISC training. The number of lessons needed to acquire CISC skills differed significantly depending on the EDSS (Spearman r=0.682, P=0.0003), but the total cognitive decline subscore did not influence the ability to learn CISC. Only 13% (3/23) of the PwMS failed to learn CISC. The ability to learn CISC depended on the number of lessons needed to acquire CISC (r=-0.499, P=0.0313) and the EDSS score (r=-0.433, P=0.0390) but not on the course of the disease (r=0.125, P=0.5696) or on cognitive decline (r=-0.311, P=0.1480). After 3 months of follow-up, 30% (6/20) of the PwMS had ceased performing CISC. A follow-up indicated no statistically significant correlations among any of the subscores of the cognitive test battery, the EDSS score, the course of the disease, and the time required to learn CISC and effective bladder management., Conclusions: Our study thus confirmed that most (87%) PwMS were able to learn CISC in spite of cognitive dysfunction and therefore to improve their quality of life.

Background: Hereditary spastic paraplegia (HSP) is a clinically and genetically heterogeneous disorder, with a variable reported prevalence ranging from 0.5 to 12 per 100,000. The aim of this retrospective study was to evaluate the prevalence of HSP and estimate the percentage of SPG4 mutations in the Estonian population., Methods: A simple model with multiple data sources was selected to enable as many patients as possible to be detected. All relevant case histories from Estonian regional neurological centers for the last 20 years were reviewed; all neurologists and general practitioners were contacted., Results: A total of 737 case records were captured for secondary evaluation. Among these cases, 88 potential HSP-affected subjects were identified. During this study 59 patients with HSP were identified, giving a crude prevalence rate of 4.4 per 100,000. Eleven persons (21.6% of all studied Estonian HSP patients) with HSP were found to have mutations in the spastin gene (SPG4)., Conclusions: Our epidemiological data are comparable with the results from epidemiological studies performed elsewhere, indicating that the clinical diagnostic management of HSP patients in Estonia is adequate and the chosen methodological approach for data collection was reliable., (2008 S. Karger AG, Basel.)

Objective: To evaluate how effectively one question 'Are you depressed?' works as a screening tool for depression in people with multiple sclerosis., Design: The results from a single question were compared with formal clinical diagnosis and the classification from a standard questionnaire., Setting: Estonian Multiple Sclerosis Centre, from October 2001 to April 2002., Subjects: One hundred and thirty-four consecutive inpatients with multiple sclerosis., Intervention: During two weeks of inpatient stay the mood disorder was analysed. On the basis of clinical interview and Beck Depression Inventory the diagnosis of depression was confirmed., Main Measures: Beck Depression Inventory and structured clinical interview., Results: Fifty-seven per cent (77/134) of people with multiple sclerosis answered 'Yes' to the question 'Are you depressed?'. The diagnosis of depression was confirmed in 94% (72/77) of people with multiple sclerosis and not confirmed in 6% (5/77). Hence, the screening test sensitivity was 91%. Forty-three per cent (57/134) answered 'No'; 70% (40/57) did not have depression. In this case the sensitivity was 54%. In this group 30% (17/57) were actually depressed according to tests and clinical impression. The age, sex, duration of disease, cognitive abilities and physical disability did not influence consistency of the answers with test results and clinical opinion., Conclusions: One-question interview is a useful tool for screening for depression in people with multiple sclerosis as it confirms existing depression (sensitivity 91%), but the results should be treated with caution if the person denies mood problems.

Anticholinergics and intermittent catheterization are the cornerstones of bladder management in early multiple sclerosis (MS). In advanced MS however, bladder management is based more on tradition than on evidence. Nurses seem to deal with catheter problems and chronic incontinence. Despite the abundant use of indwelling catheters, there is a lack for guidelines on catheter-induced problems. The psychosexual and social impact of bladder problems in advanced MS is often neglected. The international multidisciplinary special interest group on sexual, urological and bowel dysfunction in MS (SUBDIMS) as a special interest group of the Rehabilitation in Multiple Sclerosis (RIMS) was confronted with a high variability in practice and a lack of guidelines. A literature review was prepared during three multidisciplinary expert meetings. This review will be the basis of further initiatives to improve the urological treatment of patients with advanced MS.

The aim of the study was to explore personality traits as predictors of coping with disease-related distress in patients with multiple sclerosis (MS). All patients with clinically definite MS in a city with a population of approximately 100000 were asked to complete the NEO Personality Inventory and a multidimensional coping inventory (COPE). There was an 83% response rate yielding 49 patients for the study population and 49 controls, matched for age, gender and educational level to the MS-patients, were used as comparison. Only Neuroticism correlated significantly with emotion-focused coping in both groups. Extraversion and Openness to Experience were linked to task-oriented coping strategies in normal controls but not in the MS-group. Agreeableness was associated with avoidance-oriented coping strategies only in the MS-group. Thus, the relation of certain personality characteristics to the choice of strategies for coping with the disease-related distress appear to differ from coping with stressful problems in everyday life. As dispositional characteristics may interfere with adaptive coping responses, analysis of personality traits and coping strategies could contribute while attempting to relieve the consequences of chronic disease on everyday life.

Objective: To develop an international services and needs assessment instrument (SUN) for people with multiple sclerosis and their carers and to pilot this in different countries of the European Community., Design: Interview study of people with multiple sclerosis, their carers and nominated key professionals examining the unmet needs of patients and carers., Setting: Belgium, Estonia, Greece, Italy and the United Kingdom., Main Outcome Measures: Needs assessment questionnaire., Results: The study comprised 137 people with multiple sclerosis, 125 carers and 111 professionals. Patients reported on average 2.9 unmet needs for themselves; their carers and professionals reported on average 2.4. Needs were categorized into seven broad categories. Due to difficulties experienced by the local researchers in distinguishing between needs and objectives a large proportion of needs had to be assigned to the 'other' category., Conclusions: The SUN is a valuable and practicable tool for the identification of unmet needs for people with multiple sclerosis and their carers. Formal validation and reliability testing of the different language versions is recommended.

Epidemiological studies were performed in South Estonia to establish the prevalence rate of multiple sclerosis (MS) and motor neurone disease (MND). The case finding method included information from the hospital records of the central hospital in the region-the University Hospital (for MS from 1942 to 1989), from all neurologists in the region, from the Estonian MS Society and Association of Muscular Disorders, and from nursing homes in the region. The prevalence day was 31 December 1989. MND incidence was established for the period of 1986-1995. The results demonstrated high prevalence rates of MS among native Estonians (55.3 per 100 000), somewhat lower prevalence among native-born representatives of other nationalities (43.6 per 100 000) and the lowest prevalence rate of MS among non-Estonian immigrants (26.6 per 100 000). The differences were not statistically significant. The results for MND demonstrated the opposite pattern. The mean annual incidence rate of MND for 10 years was statistically significantly higher among people of other nationalities (2.5 per 100 000) and Russians (2.6 per 100 000), and lower in native-born Estonians (1.1 per 100 000). No differences in health care or clinical picture were established. The reasons for the demonstrated differences in MND incidence remain unclear., (Copyright 1999 Lippincott Williams & Wilkins.)

The current study evaluated the diagnostic standards of MND and epidemiological markers of MND in Estonia. A total of 108 patients were referred to the University Hospital from 1986 to 1995 with the first suggested diagnosis or final diagnosis of amyotrophic syndrome, amyotrophic lateral sclerosis (ALS), progressive bulbar paralysis (PBP) or progressive muscular atrophy (PMA). In addition neurologists of the region and the National Society of Neuromuscular disorders were contacted. Some 94 patients satisfied the diagnostic criteria. The annual incidence rate in South Estonia and in the city of Tartu ranged from 0.5 to 2.8 per 100,000. The mean annual incidence rate in Tartu is 1.98 and in South Estonia in general 1.3. The highest incidence rate was 8.3 for men in the age group 60 to 64 years and 7.49 in the age group 70-74; among female patients the highest incidence rate -4.6 was in the age group from 65 to 69.
