Abstract
Verbal fluency (VF) evaluates language and cognitive abilities. This study compared VF in Relapsing-Remitting Multiple Sclerosis (RRMS) and healthy controls (HC), examining variables including correct responses (CR), mean cluster size (MCS), switches (S), and fluency difference score (FDS). RRMS participants were subgrouped by Expanded Disability Status Scale (EDSS), to explore the relationship between MS severity and VF. Twenty-four RRMS participants and matched HCs underwent Mini-Mental State Exam and VF Test. Statistical analysis compared VF between RRMS subgroups based on severity levels, and in HC. RRMS significantly impacted the CR, and S (CRSF p = 0.01, SSF p = 0.002; CRPF=0.002, SPF p = 0.002), while there was no significant difference in FDS between RRMS groups (p = 0.9). No significant relationship was found between EDSS scores, and VF subtests (CRSF p = 0.061, MCSSF p = 0.46, SSF p = 0.051, CRPF p = 0.521, MCSPF p = 0.966, SPF p = 0.599). In RRMS, our results demonstrate impairments in all VF parameters except the MCSSF+PF, and FDS. This study suggests that intact MCSSF+PF may reflect preserved verbal memory and word recall, while significant switching differences may indicate impaired cognitive flexibility. Similar FDS to those of HC suggest that no performance discrepancy in subtests in RRMS. Intact MCS might be a distinctive pattern in the early clinical stage of MS.

Abstract
Background: This research aims to compare e-health literacy of technology users and nonusers in people with multiple sclerosis (MS) and to investigate whether there are correlations between age, duration of MS, gender, marital status, and e-health total scores. Methods: This descriptive study was carried out with a web-based questionnaire. The questionnaire was sent to 300 patients with MS who were registered at Istanbul University-Cerrahpasa Medical Faculty Neurology Department. Results: A total of 156 people (mean age: 35.33 ± 10.47 years) participated in the survey. Smartphone 98.1% (n = 153) was the mostly used device. Rate of using Google and recommended websites about MS was 94.25% (n = 145) and 73.9% (n = 113), respectively. e-Health literacy of both the tablet and recommended websites users significantly differed from that of nonusers (p = 0.007 for both). Participants' e-health literacy total score was found to weakly, but significantly, correlate with their age, marital status, and education level (rho: -0.161, p = 0.044; rho: 0.172, p = 0.032; rho: -0.192, p = 0.016, respectively). Conclusions: With developments in digital technologies, it is important to identify the access status of people with MS to improve daily clinical management and implement further motor and cognitive rehabilitation. Therefore, determining the health literacy of individuals with MS and providing education on this subject will reduce the information pollution.

Mult Scler Relat Disord 2024; 81:105366. [PMID: 38104477 DOI: 10.1016/j.msard.2023.105366] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 12/01/2023] [Accepted: 12/07/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND Over the past decade, the prevalence of Multiple Sclerosis (MS) has increased in Turkey. However, the prevalence of MS in Middle Anatolia, specifically Afyonkarahisar, remains unknown. Additionally, the potential link between economic status and MS has not yet been explored in Turkey. METHODS A stratified sampling method was employed to select samples from the population residing in Afyonkarahisar City Center, taking into account demographic factors such as income level, sex, and age. The sample size was calculated using the formula N = p.q.Zα2/d2, where an average prevalence rate of 70/100,000 was considered based on previous studies. The minimum sample size was 29,858. Considering incomplete, inaccurate, and low-reliability data, data were collected from 30,500 individuals and 30,408 individuals were evaluated. RESULTS The prevalence of Multiple Sclerosis in the center of Afyonkarahisar was 105.2 per 100,000 individuals. Upon investigating the association between economic status and MS prevalence, the findings revealed rates of 193.6 per 100,000 in individuals with high income, contrasting with 80.2 per 100,000 in those with low income. Notably, a heightened prevalence of MS is evident among individuals with higher income levels. CONCLUSION This study revealed a significantly elevated prevalence of MS in Afyonkarahisar, the highest in Turkey. The inverse correlation between the prevalence of MS and socioeconomic status is intriguing. Possible reasons for the high prevalence include the relatively new and specific geologic and environmental conditions in the area.

Abstract
The prevalence of multiple sclerosis (MS) in Asian countries is thought to be lower than in Western countries, with Asian populations presenting 80% less risk of MS than white populations. Incidence and prevalence rates in Asian countries are therefore not well defined and their association with rates in neighboring countries, as well as with ethnic, environmental, and socioeconomic factors, are not well understood. We performed a comprehensive literature review of epidemiological data from China and neighbouring countries to study the frequency of the disease, focusing on prevalence, and the progression over time and the influence of sex-related, environmental, dietary, and sociocultural factors. Prevalence rates in China range between 0.88 cases/100,000 population in 1986 and 5.2 cases/100,000 population in 2013, with a non-significant upwards trend (p = .08). The increase observed in Japan, where figures ranged between 8.1 and 18.6 cases/100,000 population was highly significant (p < .001). Prevalence rates in countries with predominantly white populations are considerably higher and have increased over time, reaching 115 cases/100,000 population in 2015 (r2 = 0.79, p < .0001). In conclusion, the prevalence of MS in China appears to have risen in recent years, although Asian populations (including Chinese and Japanese populations, among others) appear to present less risk than other populations. Within Asia, geographical latitude appears not to be a determining factor for developing MS.

Abstract
BACKGROUND Galectins are a family of endogenous mammalian lectins involved in pathogen recognition, killing, and facilitating the entry of microbial pathogens and parasites into the host. They are the intermediators that decipher glycan-containing information about the host immune cells and microbial structures to modulate signaling events that cause cellular proliferation, chemotaxis, cytokine secretion, and cell-to-cell communication. They have subgroups that take place in different roles in the immune system. The effect of galectin-8 on multiple sclerosis disease (MS) has been studied in the literature, but the results seemed unclear. In this study, we aimed to determine anti-galectin-8 (anti-Gal-8) levels in MS and their potential use as biomarkers. METHODS In this experimental study, 45 MS patients diagnosed according to McDonald criteria were included in the patient group. The healthy control group contained 45 people without MS diagnosis and any risk factors. Demographic data, height, weight, body mass index, blood glucose, thyroid-stimulating hormone, alanine transaminase, aspartate transaminase, creatinine, low-density lipoprotein, anti-Gal-8 levels, the prevalence of hypertension, diabetes mellitus and coronary artery disease were recorded. In addition, the expanded disability status scale and disease duration were evaluated in the patient group. Data were presented as mean ± standard deviations. RESULTS The mean blood anti-galectin-8 value of the patient group was 4.84 ± 4.53 ng/mL, while it was 4.67 ± 3.40 ng/mL in the control group, and the difference in these values was found statistically insignificant (P > .05). Moreover, body mass index, glucose, alanine transaminase, aspartate transaminase, thyroid-stimulating hormone, and low-density lipoprotein levels were also statistically insignificant (P > .05). CONCLUSION This study examined anti-Gal-8 levels in MS patients. The relationship between MS and galectin-8 and anti-Gal-8 levels in patients needs further clarification. As a result, the study's results could help elucidate the pathogenesis of MS and give more evidence for diagnosis.

Abstract
Background Secondary progressive multiple sclerosis (SPMS) is a subtype of multiple sclerosis (MS), which is a chronic neurological disease, characterised by inflammation of the central nervous system. Most of MS patients eventually progress to SPMS. This study estimates the prevalence of SPMS in the United States of America, Europe, Canada, Australia, and Brazil. Methods A systematic literature search of the Medline and Embase databases was performed using the OVID™ SP platform to identify MS epidemiological studies published in English from database inception to September 22, 2020. Studies reporting the prevalence of MS and proportion of SPMS patients in the included population were selected. The pooled prevalence of SPMS was calculated based on the proportion of SPMS patients. The Loney quality assessment checklist was used for quality grading. A meta-analysis of the proportions was conducted in RStudio. Results A total of 4754 articles were retrieved, and prevalence was calculated from 97 relevant studies. Overall, 86 medium- and high-quality studies were included in the meta-analysis. Most studies were conducted in European countries (84 studies). The estimated pooled prevalence of SPMS was 22.42 (99% confidence interval: 18.30, 26.95)/100,000. The prevalence of SPMS was more in the North European countries, highest in Sweden and lowest in Brazil. A decline in SPMS prevalence was observed since the availability of oral disease-modifying therapies. We also observed a regional variation of higher SPMS prevalence in urban areas compared with rural areas. Conclusion High variability was observed in the estimated SPMS prevalence, and the quality of the studies conducted. The influence of latitude and other factors known to affect overall MS prevalence did not fully explain the wide range of inter-country and intra-country variability identified in the results.

Abstract
Predicting treatment failure and switching effective treatment immediately in patients with multiple sclerosis (MS) is important. We aimed to evaluate the usefulness of Modified Rio score (MRS) in predicting treatment failure in MS patients. This is a retrospective study, which was conducted in two University Hospital. 129 MS patients treated with İnterferon or glatiramer-acetate from 2 clinical sites, were retrospectively selected. MRS was calculated after the first year of therapy. Treatment failure was defined as the presence of a 1 point increase in EDSS, 2 clinical attacks, 1 clinical attack and progression, 1 clinical attack and new lesion on MRI except associated with an attack, or new lesion in 2 different MRI taken at least 3 months apart. The sensitivity, specificity, positive and negative predictive values of the MRS in predicting treatment failure were determined. 71 (55%) patients with score '0', 41 (31.8%) patients with score '1', 11 (8.5%) patients with score '2', 6 (4.7%) patients with score '3' were detected. 14 patients needed treatment switching during the first three years of the treatment. Sensitivity was 57%, specificity was 92%, positive predictive value was 95%, negative predictive value was 47% and accuracy was 89%. Modified Rio score (MRS) was found to be effective in determining the treatment failure as mentioned before. This study will be useful for clinicians who evaluate the treatment failure like us, and this study revealed that the MRS may also help predict treatment failure.

Abstract
BACKGROUND The multiple sclerosis (MS) landscape has changed over the past two decades across the world and in the Middle East. The Middle East is an ethnically diverse region located between 12° and 42° of latitude and 35° and 54° of longitude and varying altitudes. The magnitude of the shifts observed in the epidemiology and management of MS differ in each region and from country to country. OBJECTIVES The aim of this study was to provide a clinicodemographic overview of the cohorts of patients contributed to MSBase, a large international MS registry, in the Middle East and describe disease-modifying treatment (DMT) utilization in the different countries within the region. Understanding the differences between these cohorts is integral to interpretation of the studies conducted using registry data and provides insight into clinical practice in these cohorts. METHODS The MSBase registry was searched for patients with MS or clinically isolated syndrome from the Middle Eastern countries with data captured between 2009 and 2018. In 2-year epochs, and with special focus on the most recent epoch (2017-2018), we explored the demographic, clinical characteristics and treatment exposures of the studied cohorts and reported the results using standard descriptive statistics. RESULTS Over the 10-year study period, 13,356 patients from 17 centers in 8 Middle Eastern countries fulfilled the inclusion criteria. The represented countries were Egypt, Iran, Kuwait, Lebanon, Oman, Saudi Arabia, Turkey and the United Arab Emirates. Overall, the represented cohort was young (median 36 years, quartiles 29-45) and captured relatively early after the onset of MS (median disease duration < 10 years, quartiles 3-12). The relapsing-remitting phenotype was the most prevalent phenotype in all countries (73-97%) and the highest proportion of progressive MS was reported in Saudi Arabia (12%). Median Expanded Disability Status Scale (EDSS) ranged from 0 to 3, depicting a mildly disabled cohort, with the exception of Saudi Arabia where the median EDSS was 4 (quartiles 1.5-6.5). The median relapse frequency was highest in Lebanon (median 1.03, 95% CI 0.94-1.16) followed by Egypt (median 1.02, 95% CI 0.89-1.24) and lowest in Saudi Arabia (median 0.70, 95% CI 0.58-0.95) and Kuwait (median 0.75, 95% CI 0.71-0.80). The treatment landscape greatly varied between different countries. Platform injectable therapies were mostly utilized in Egypt, Iran and Turkey (86%, 79% and 53%, respectively), while oral therapies and monoclonal antibodies were more commonly used in Kuwait, Lebanon and the United Arab Emirates (87.2%, 67.3% and 58.7%, respectively). CONCLUSION Patients in the Middle East enrolled in a large multinational registry are representative of the general MS population. The spectrum of therapies used in the individual countries, however, is highly variable. Further studies that include rural and non-academic practices are needed to enhance our understanding of the MS cohorts in the Middle East.

Abstract
BACKGROUND The effects of adipokines have been investigated in multiple sclerosis (MS) in the literature. Results are uncertain, and subgroups like adropin have not been previously studied. We primarily aimed to determine leptin and adropin levels in MS and their potential use as a biomarker. METHODS This study was an experimental research. While 44 MS patients diagnosed according to McDonald criteria were included in the patient group, 40 people without MS diagnosis and risk factors took part in the control group. Demographic data, height, weight, body mass index, blood glucose, thyroid-stimulating hormone, alanine transaminase, aspartate transaminase, creatinine, low-density lipoprotein, leptin, adropin levels, presence of hypertension, diabetes mellitus, coronary artery disease were recorded. Expanded disability status scale and disease duration were also evaluated in the patient group. Our data were presented as mean ± standard deviations. RESULTS The mean blood leptin value of the patient group (6.12 ± 5.34 ng/mL) was significantly lower than the value of the control group (13.02 ± 8.25 ng/mL) (P < .001). The patient group had a mean adropin level of 504.12 ± 311.17 ng/mL, which was significantly lower than that of the control group (747.0 ± 309.42 ng/mL) (P < .001). Statistically insignificant differences were found between their body mass index, glucose, alanine transaminase, aspartate transaminase, thyroid-stimulating hormone, low-density lipoprotein levels (P > .001). CONCLUSION This is the first study that has evaluated adropin levels in patients with MS. The relationship between MS and leptin levels is still unclear. Therefore, our study might be helpful to elucidate MS pathogenesis and provide supportive criteria for diagnosis.

Abstract
BACKGROUND Multiple sclerosis (MS) is an inflammatory demyelinating CNS disease and the most common neurological immune-mediated disorder. Due to its progressive format, it affects patients' quality of life (QoL) significantly. This study aimed to evaluate epidemiologic parameters of MS in the Asia and Oceania continents. METHODS A comprehensive literature search on October 1st, 2020, was performed in PubMed, Scopus, and Web of Science to retrieve original population-based studies on MS epidemiology in the Asian and Oceanian countries, published between January 1st, 1985 and October 1st, 2020. The designed search strategy was repeated for each country, and the relevant referenced articles were added to our database. A random-effect model was used to combine the epidemiological estimates, and subgroup analysis was also performed by continent, region, and country, when possible. Meta-regression analysis was done to evaluate the effects of Human Developmental Index (HDI), latitude, and study period on the epidemiologic parameters. RESULTS A total of 3,109 publications were found, of which 89 articles met the eligibility criteria and were included for data extraction. These articles provided data on prevalence, incidence, and mean age at disease onset in 18 countries in Asia and Oceania, including Iran, Turkey, Cyprus, Kuwait, Saudi Arabia, Qatar, UAE, Jordan, Israel, India, Malaysia, China, Hong Kong, Taiwan, Republic of Korea, Japan, Australia, and New Zealand. The pooled total prevalence, incidence, and mean age of onset in Asia and Oceania were 37.89/100000 (95% CI: 35.65 - 40.142), 2.40/100000 (95% CI: 2.22 - 2.58), and 28.21 (95% CI: 27.55 - 28.88), respectively. MS prevalence and incidence in the female gender (68.7/100000 and 4.42/100000, respectively) were infinitely higher than in the male gender (24.52/100000 and 2.06/100000, respectively). Our subgroup analysis showed that MS was much more prevalent in Australia and West Asia among the studied area. The meta-regression showed that the total incidence decreased with an increase in the HDI, and the total prevalence in Asia increased with increasing latitude gradients. Also, the study period had a positive effect on the total prevalence and incidence in Asia and Oceania. CONCLUSION MS prevalence and incidence have increased in recent decades. This study highlights the need for further studies to elucidate MS's geographical and temporal variations' exact etiologies.

Association between familial Mediterranean fever and multiple sclerosis: A case series from the JIR cohort and systematic literature review. Mult Scler Relat Disord 2021; 50:102834. [PMID: 33609923 DOI: 10.1016/j.msard.2021.102834] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Revised: 01/19/2021] [Accepted: 02/05/2021] [Indexed: 02/01/2023]
Abstract
INTRODUCTION Familial Mediterranean fever (FMF) is the most frequent monogenic autoinflammatory disorder; and leads to the uncontrolled production of interleukin (IL)-1β. Multiple sclerosis (MS) is an inflammatory disease of the central nervous system; and its development seems to be partly correlated with IL-1β levels. It is hypothesized that FMF could be associated with MS. We aim to describe the features of patients displaying both diseases and to investigate the MEFV mutation rate in MS patients. METHODS Patients with definite MS were retrieved from the cohort of FMF patients in the Reference Center for Rare Auto-inflammatory Diseases and Amyloidosis (CEREMAIA). We also performed a systematic literature review of articles from PubMed that were published from 1990 to 2020. RESULTS Twenty-four patients were included in the case series: five patients (1.3%) from our cohort of 364 and 19 patients from the literature. The sex ratio was 2:1. The mean age at diagnosis of FMF was 19 years old; and that for MS was 29 years old. Seven studies investigating the MEFV mutation rate in MS patients were included. Three studies found a higher mutation rate in MS patients than in the control group. CONCLUSION FMF and MS features were comparable to those of patients with unrelated diseases; and MEFV mutation carriage was not positively correlated with MS. However; MS prevalence in FMF patients was higher than was expected in a healthy population. To a lesser extent; FMF prevalence in MS patients was higher than expected in a healthy population and the difference might not be significant. These data suggest that FMF could be associated with MS; and further studies are needed to investigate a potential causal association.

Abstract
The prevalence of multiple sclerosis (MS) in Asian countries is thought to be lower than in Western countries, with Asian populations presenting 80% less risk of MS than white populations. Incidence and prevalence rates in Asian countries are therefore not well defined and their association with rates in neighboring countries, as well as with ethnic, environmental, and socioeconomic factors, are not well understood. We performed a comprehensive literature review of epidemiological data from China and neighbouring countries to study the frequency of the disease, focusing on prevalence, and the progression over time and the influence of sex-related, environmental, dietary, and sociocultural factors. Prevalence rates in China range between 0.88 cases/100,000 population in 1986 and 5.2 cases/100,000 population in 2013, with a non-significant upwards trend (p = .08). The increase observed in Japan, where figures ranged between 8.1 and 18.6 cases/100,000 population was highly significant (p < .001). Prevalence rates in countries with predominantly white populations are considerably higher and have increased over time, reaching 115 cases/100,000 population in 2015 (r2 = 0.79, p < .0001). In conclusion, the prevalence of MS in China appears to have risen in recent years, although Asian populations (including Chinese and Japanese populations, among others) appear to present less risk than other populations. Within Asia, geographical latitude appears not to be a determining factor for developing MS.

Abstract
OBJECTIVE Studies focusing attention on the effects of environmental pollution on the etiology of multiple sclerosis (MS) are on the increase. The aim of this study was to determine MS prevalence in a city home to an iron and steel factory which causes air pollution. METHODS The study was designed as a cross-sectional, population-based, descriptive epidemiologic study. Ereğli city, which has an iron and steel factory and proven air pollution, was screened. Additionally, Devrek city, which is a rural and clean city, located 40 km away from Ereğli was assigned and results were compared. A validated questionnaire was used for screening. McDonald 2010 criteria were used to diagnose cases. RESULTS 32 261 people were screened in Ereğli, and 21 963 people were screened in Devrek. In total, 41 patients were diagnosed with clinical definite MS. Crude prevalence was found to be 96.1/100 000 in Ereğli and 45.5/100 000 in Devrek. The mean age of patients was 39.8, and the female/male ratio was 1.9. CONCLUSION The results of this study indicate a more than double MS prevalence rate in the area home to an iron and steel factory when compared to the rural city. This supports the hypothesis that air pollution may be a possible etiological factor in MS.

Abstract
Background/aim Multiple sclerosis (MS) is a common neurological disorder that can be a leading cause of nontraumatic disability in several countries. Recent reports have indicated a moderate to high risk of MS in European countries. In this study, we examined the prevalence of MS in a well-defined urban population of provincial center in Sivas Province in Turkey. Materials and methods This study sampled all registered residents of urban areas of provincial center in Sivas Province in April 2017 and 2018 January. All the included patients met the McDonald 2010 criteria. Medical records were reviewed, including all available previously acquired magnetic resonance imaging data. All patients were subsequently subjected to neurologic examination to confirm the MS diagnosis. Results We identified 21 possible MS patients, with MS diagnosis confirmed in 19. The prevalence of MS was 288 per 100,000 inhabitants. Conclusion For future studies, these high ratio results can be used in regional and national comparisons to determine cofactors contributing to the high prevalence of MS in our region and can help health-decision makers to better plan healthcare policies to improve neurological services and awareness about multifaceted clinical presentations of MS.

Abstract
The prevalence of multiple sclerosis (MS) has significantly increased all over the world. Recent studies have shown that Turkey has quite a high prevalence. The aim of this study is to estimate prevalence in the Mediterranean and Black Sea regions of Turkey and to compare the results.This study was designed as a door to door survey in 3 cities. One is located in the Mediterranean region (South), 2 are located in the Black Sea region (North). A previous validated form was used for screening in the field. The patients were examined first in the field, then in the regional health facility. McDonald criteria were used for the diagnosis.In total, 26 patients were diagnosed with MS. The prevalence was found to be 18.6/100,000 in Artvin (Black Sea region), 55.5/100,000 in Ordu, (Black Sea region), 52.00/100,000 in Gazipaşa (Mediterranean region). The female/male ratio was 2.25.This study is the first prevalence study which was conducted in the Mediterranean City (South) of Turkey. The prevalence rate was found to be higher than expected in the Mediterranean city of Gazipaşa. The results showed that the prevalence varies from region to region. Latitude difference was not observed.

Abstract
Background and Purpose Multiple sclerosis (MS) is an autoimmune disease characterized by inflammatory demyelination. Recent studies have shown that long-term exposure to air pollutants (including PM10 particulates) is potentially an environmental risk factor for MS. We aimed to determine the prevalence rates of MS in two cities with different levels of air pollution. Methods This door-to-door population-based study was conducted between April 2014 and June 2015. Two cities were screened for the prevalence rates of MS: 1) Karabük, which borders an iron-and-steel factory, and 2) Akçakoca, which is a coastal city located in the same region. A validated survey form was used for screening MS. The 2010 McDonald Criteria were used for diagnosing MS. The patients were examined twice, first by a neurology assistant in the field and then by a senior neurologist in public health centers in the cities. Results The prevalence of MS was 95.9/100,000 in Karabük and 46.1/100,000 in Akçakoca. In total, 33 patients were diagnosed with clinically definite MS. The female/male ratio was 1.5, and 21 patients were diagnosed with relapsing-remitting MS, 9 with secondary progressive MS, and 3 with primary progressive MS. Conclusions We found that the prevalence of MS was more than two fold higher in Karabük than in Akçakoca, which supports a link between air pollution and the pathogenesis of MS. However, larger etiological and epidemiological studies are needed to confirm this hypothesis.

Abstract
INTRODUCTION This research was conducted to adapt the Monitoring My Multiple Sclerosis (MMMS) scale, which is a scale used for self-evaluation by multiple sclerosis (MS) patients of their own health and quality of life, to Turkish and to determine the psychometric properties of the scale. METHODS The methodological research was conducted in the outpatient MS clinic of a university hospital between January and September 2013. The sample in this study consisted of 140 patients aged above 18 who had a diagnosis of definite MS. Patients who experienced attacks in the previous month or had any serious medical problems other than MS were not included in the group. The linguistic validity of MMMS was tested by a backward-forward translation method and an expert panel. Reliability analysis was performed using test-retest correlations, item-total correlations, and internal consistency analysis. Confirmatory factor analysis and concurrent validity were used to determine the construct validity. The Multiple Sclerosis Quality of Life-54 instrument was used to determine concurrent validity and the Expanded Disability Status Scale, Hospital Anxiety and Depression Scale, and Mini Mental State Examination were used for further determination of the construct validity. RESULTS We determined that the scale consisted of four factors with loadings ranging from 0.49 to 0.79. The correlation coefficients of the scale were determined to be between 0.47 and 0.76 for item-total score and between 0.60 and 0.81 for items and subscale scores. Cronbach's alpha coefficient was determined to be 0.94 for the entire scale and between 0.64 and 0.89 for the subscales. Test-retest correlations were significant. Correlations between MMMS and other scales were also found to be significant. CONCLUSION The Turkish MMMS provides adequate validity and reliability for assessing the impact of MS on quality of life and health status in patients.

Abstract
INTRODUCTION Multiple sclerosis (MS), a demyelinating disease of the central nervous system, is increasing in prevalence worldwide. Other than small-scale studies, there is a scarcity of data on the prevalence of MS in Turkey. The present study aimed to elucidate the prevalence of MS in the Middle Black Sea Region and the demographic characteristics of patients. METHODS Patients living in the Middle Black Sea Region and who were diagnosed with MS were included. The study was designed based hospital of Turkey. RESULTS A total of 1,787 patients were interviewed, and a diagnosis of MS was confirmed in 1,584. The prevalence of MS was found to be 43.2/100,000 in the Middle Black Sea Region; this was calculated based on the total population and number of patients in the provinces and districts in this region. The mean age at the disease onset was 29.39±7.6 years. Among the patients, 1,299 (81.9%) had relapsing-remitting MS, 74 had secondary progressive MS, 77 had relapsing-progressive MS, 47 had primary progressive MS, and 87 had clinically isolated syndrome. CONCLUSION The Middle Black Sea Region was found to have a high risk for the prevalence of MS. This study is the most comprehensive epidemiologic study having the largest geographical distribution on the prevalence of MS in Turkey.

Abstract
The epidemiology of multiple sclerosis (MS) includes a consideration of genetic and environmental factors. Comparative studies of different populations have revealed prevalence and incidence rates that vary with geography and ethnicity. With a prevalence ranging from 2 per 100,000 in Japan to greater than 100 per 100,000 in Northern Europe and North America, the burden of MS is similarly unevenly influenced by longevity and comorbid disorders. Well-powered genome-wide association studies have investigated the genetic substrate of MS, providing insight into autoimmune mechanisms involved in the etiopathogenesis of MS and elucidating possible avenues of biological treatment.

Abstract
OBJECTIVE The aim of this study was to evaluate the association between different disability states in patients with multiple sclerosis (MS) as determined by the expanded disability status scale (EDSS) and dental-periodontal measures. SUBJECTS AND METHODS Eighty patients with MS (64 females and 16 males) were included in this study. Data on MS types, attack frequency, disease duration, EDSS scores and orofacial complaints prior to an MS attack were obtained from medical records. The plaque index (PI), probing depth (PD), clinical attachment level (CAL), gingival index (GI), decayed-missing-filled teeth (DMFT) index and number of present teeth were measured during one dental examination for each subject. The MS patients were divided into the following 2 groups based on their EDSS scores: low physical disability (L-DS) and high physical disability (H-DS). Differences in dental parameters between groups of low and high disability were investigated. p < 0.05 was considered statistically significant. RESULTS The mean age of the participants was 38.06 ± 10.11 years. Age and disease duration were higher in the H-DS MS group than in the L-DS MS group (p < 0.05). The PI, PD and GI were higher and the number of filled teeth was lower in the H-DS MS group than in the L-DS MS group (p < 0.05). The EDSS scores of the H-DS MS group presented a significant correlation with the number of decayed teeth (r = -0.548, p = 0.005). Orofacial complaints prior to an MS attack were reported by 18 (22.5%) patients. CONCLUSION Oral measurements revealed various differences between groups of low and high disability in MS patients. In addition, some maxillofacial-oral complaints prior to an MS attack were observed.

Abstract
OBJECTIVE To estimate the economic burden of multiple sclerosis (MS) in Turkey, including the relapses and disease severity, and to evaluate the quality-of-life of MS patients. METHODS The Treatment Experience, Burden and Unmet Needs (TRIBUNE) study was a multi-national, cross-sectional, retrospective, burden-of-illness survey. Total costs were calculated using unit costs derived from price lists or published literature, where relevant, and inflated to 2011 TL prices. RESULTS A total of 295 MS patients (74% females) were included in the analysis. The population had a mean age of 36 years; 73% had the relapsing-remitting form. Mean Expanded Disability Status Scale (EDSS) score was 2.2. Twenty-two per cent of the MS patients required hospitalization in the past year and spent an average of 29.2 days/year in hospital. These values were 43% and 5.6 days for the outpatients, respectively. Total cost per patient/year was 18,700 TL (Turkish Lira). Total costs for patients with mild, moderate, and severe disability were 15,418 TL, 26,002 TL, and 44,208 TL per patient/year, respectively. The mean EuroQol 5D scores in the same groups were 0.73, 0.52, and 0.05, respectively. CONCLUSIONS Multiple sclerosis imposes a significant economic burden on patients and society in Turkey.

Abstract
BACKGROUND The geographic distribution of multiple sclerosis (MS) is classically divided into three zones based on frequency that were established by Kurtzke in the early 1970s. In recent years, an increasing number of epidemiological studies have shown significantly higher MS prevalence and incidence rates. OBJECTIVE The aim of this study was to review and update the geographic distribution of MS using incidence, prevalence and disease duration from the latest epidemiology surveys. METHODS We conducted a systematic review of articles on MS epidemiology published between January 1, 1990 and December 31, 2012. RESULTS MS studies were grouped by continent: the Americas, Europe, Asia, Australia/New Zealand, and Africa. A total of 101 studies were identified according to the inclusion criteria, and 58 reported incidence estimates. Globally, the median estimated incidence of MS was 5.2 (range: 0.5-20.6) per 100,000 p-yrs, the median estimated prevalence of MS was 112.0 (with a range of 5.2-335) per 100,000 p-yrs, and the average disease duration was 20.2 years (range: 7.6-36.2). CONCLUSION In the past few decades, the global prevalence and incidence patterns of MS have changed dramatically. Regardless of the reason of increasing prevalence and incidence rate, we suggest the need for a novel classification system based on global MS disease burden. Adopting such a system would improve economic efficiency and prioritization in health policy planning for MS.

Abstract
PURPOSE The aim of the study was to present the effects of the disease and analyze the relationship between activities of daily living (ADL) and self-care in multiple sclerosis (MS) patients who have had the disease for the first 10 years. DESIGN This study was a descriptive cross-sectional study. METHODS A total of 67 patients who fit the inclusion criteria of the study and volunteered to participate were included in the sample. Data were collected using the Exercise of Self-Care Agency Scale and the Barthel Index. FINDINGS The mean age was 38.43±9.92. There was a statistically significant correlation between participants'educational backgrounds and self-care scores and between disease duration and Barthel index score (p<.05). CONCLUSIONS The self-care levels of patients who have had MS for the first 10 years are medium, and they tend to be mildly dependent in performing their ADL. The duration of MS is positively correlated with level of ADL. CLINICAL RELEVANCE In this study, it was shown that the duration of the disease in MS patients should be taken into account by rehabilitation nurses to implement effective nursing care.

Abstract
AIMS Since lower urinary tract dysfunction (LUTD) related to multiple sclerosis (MS) has a different behavior pattern than other types of neurogenic voiding dysfunction, we aimed to prepare a national consensus report for the management of LUTD due to multiple sclerosis in light of available literature. METHODS A search of available databases yielded an evidence base of 125 articles after the application of inclusion/exclusion criteria. When sufficient evidence existed, recommendations A (high), B (moderate), or C (low) were made according to the strength of evidence; recommendation D was provided when insufficient evidence existed. RESULTS Available data did not support the use of invasive urodynamics in the initial evaluation of patients with MS and LUTD. Clinical studies on the safety and efficacy of antimuscarinics and alpha-blockers in these patients were scarce and low quality. Desmopressin could be used in MS-related overactive bladder symptoms owing to its short-term effects as an adjunctive treatment. Intravesical botulinum toxin type A treatment in patients with MS and detrusor overactivity was recommended in cases of medical treatment failure or severe side effects due to antimuscarinics. Pelvic floor rehabilitation together with neuromuscular electrical stimulation was also recommended as it increased symptomatic treatment success. This systematic review was not able to find any evidence-based cut off post-void residual value for the recommendation to start clean intermittent catheterization in MS-related LUTD. CONCLUSIONS Patients with MS and LUTD could be best managed through the use of this consensus report.

Abstract
BACKGROUND Multiple Sclerosis (MS) is a neurodegenerative disease. It involves inflammation and demyelination. Since cytokines play an important role in the development of MS, genes encoding cytokines such as the Interleukin (IL)-1 family are candidate genes for MS susceptibility. OBJECTIVE To determine the relationship between IL-1 gene family and MS in the Turkish population. METHODS A total of 409 MS patients and 256 healthy controls were included in the study. IL-1A -889 (rs1800587), IL-1 RN variable number tandom repeat (VNTR), IL-1B -511 (rs 16944) and IL-1B +3953 (rs 1143634) polymorphisms were investigated from the genomic DNA, obtained via blood samples. RESULTS No association was found between IL-1A and IL-1RN polymorphisms and susceptibility to MS. However, we have found significantly decreased frequency of IL-1B -511 genotype (p = 0.004) in MS patients compared to controls. In addition, there was a significant association between IL-1B -511 (1/2) genotype and early onset MS (EOMS) (p = 0.0001). CONCLUSIONS Individuals with the 2/2 genotype of IL-1B -511 have significantly decreased incidence of MS, suggesting a protective role for this genotype in the Turkish population. Additionally, IL-1B -511 (1/2) genotype was determined as a possible risk factor for EOMS.

Abstract
BACKGROUND Based on data available, Iran is located in a low risk area for multiple sclerosis (MS). The objective of the current study is to determine the age and sex adjusted prevalence and incidence of MS in southeastern Iran. METHODS This cross-sectional case register study was conducted from January to August 2010. Considering that MS affects people aged between 16 and 50 years, we intended to find the incidence and prevalence of MS during this age range. Since all cases in this area are referred to our university hospital for confirmation of diagnosis, misdiagnosis is rare. Population data, based on the censuses carried out in 1996 and 2006, were obtained from the Iranian Bureau of Statistics to determine the number of people at risk. RESULTS Totally 206 patients were identified according to the McDonald criteria. In 2009 the age-adjusted prevalence and incidence rates of MS for 16-50 year-old adults were 13.96 and 2.67 per 100,000 persons, respectively. Based on those values; the female to male ratio was 2.18. Between 2006 and 2009, the incidence rates increased 2.4 and 2.7 times in women and men, respectively. In 2009, the prevalence rates among the age ranges of <15, 16-35, 36-50 and ≥51 years were 1.44, 14.34, 12.24 and 1.45 per 100,000 persons, respectively, and the relapsing-remitting type of MS was the most prevalent form (65.8%). CONCLUSION According to the Kurtzke geographical distribution, the authors conclude that the prevalence of MS in southeastern Iran is in the intermediate range, and the incidence rate is showing a faster growth rate, compared to previous years.

Abstract
BACKGROUND In 2008, immigrants constituted 14% of the population of Sweden, a high-risk area for multiple sclerosis (MS). We investigated the largest Swedish immigrant populations for the prevalence of MS. METHOD Data on foreign-born MS patients were retrieved from Swedish national health and population registers. We calculated observed versus expected numbers of MS patients and gender- and age-specific prevalence ratios (PR) between immigrant populations and the general population of Sweden and, where possible, of the countries of birth. RESULTS The 19 largest immigrant populations included 1327 MS patients. The global variation in MS prevalence was reflected in Sweden. The prevalence in immigrant populations who had moved to Sweden from countries with a lower MS risk was however higher than in their countries of birth. Notably, the MS prevalence in the population born in Iran was at least as high as in the general population of Sweden (men: PR = 1.10, 95% CI 0.81-1.46, p = 0.537, women: PR = 1.18, 95% CI 0.97-1.44, p = 0.855) and more than twice as high as in Isfahan, Iran (men: PR = 3.06 (95% CI 2.26-4.06), p <0.001, women: PR = 2.21 (95% CI 1.81-2.68), p <0.001). CONCLUSIONS The MS prevalence increased in migrants who moved to Sweden from countries with a lower MS risk. In the Iranian immigrant population the prevalence exceeded that in the general population of Sweden. This indicates that Iranians carry genetic factors that contribute to a higher MS risk when environmental-lifestyle MS risk factors change.

Abstract
BACKGROUND Little information exists on multiple sclerosis (MS) in Turkey. With a door-to-door survey in an urban part of Istanbul, we recently reported a prevalence rate of 101/100,000 population. We therefore investigated three rural areas of Turkey at the same latitude. METHODS The same survey methods were used for total populations of two rural areas (Kandıra and Geyve) near Istanbul, and for half the population of Erbaa, all near 40° north latitude on the Black Sea coast. RESULTS In Kandıra, 5 of 8 suspects were diagnosed as having MS among 8,171 screened, resulting in a prevalence rate of 61/100,000. Geyve with 7 MS cases in 17,016 screened had a prevalence of 41/100,000, and Erbaa with 15 MS cases in 28,177 screened one of 53/100,000. Together they showed a prevalence of 51/100,000. Of the 27 patients, 20 were women; 25 had definite and 2 possible MS, the former all with abnormal laboratory findings. Average ages were 30.5 years at onset and 39.1 years at diagnosis. Clinical features and course were typical of European MS. CONCLUSION These findings indicate that Turkey is a high-risk MS area, similar to most regions of Mediterranean Europe, where all recent increases are likely due to (undefined) environmental factors.

Abstract
BACKGROUND Sardinia is a known high-risk area for multiple sclerosis (MS), but no data for south-western Sardinia (SWS) are available. SWS has a genetically homogeneous population, apart from St Peter Island, and represents a peculiar environment related to the industrial, mineralogical and military economy. OBJECTIVE To estimate prevalence and incidence and to evaluate temporal trends and geographical distribution of MS in SWS. METHODS MS prevalence was evaluated on 31 December 2007 and crude mean annual incidence rate was defined between 2003 and 2007. Temporal trend in MS incidence was assessed using the Armitage test. To identify MS clusters, Standard Morbidity Ratio (SMR) was calculated for each village and geographical distribution prevalence by means of a Bayesian hierarchical model. RESULTS Total crude prevalence rate was 210.4 (95% CI 186.3-234.5): 280.3 (95% CI 241.4-319.3) for females, 138 (95% CI 110.1-165.8) for males. The crude mean annual incidence rate was 9.7/100,000 (95% CI 3.4-13.2): 4.7/100,000 (95% CI 2.4-17.0) and 14.6/100,000 (95% CI 11.8-34.8) for males and females respectively. MS incidence has increased over the last 50 years. Cluster analysis showed an SMR of 0.2 (95% CI 0.05-0.68, p = 0.002) on the island of San Pietro, and 2.0 (95% CI 1.35-2.95, p = 0.001) in Domusnovas. Spatial distribution of MS was confirmed by Bayesian geographical analysis. CONCLUSIONS Our data confirm Sardinia as a high-risk area for MS and support the relevance of genetic factors in MS, as evidenced in St Peter Island. However, we found an unexpectedly high MS prevalence in one village, in particular in males, suggesting an environmental influence on MS occurrence.

Abstract
The uneven distribution of multiple sclerosis (MS) across populations can be attributed to differences in genes and the environment and their interaction. Prevalence and incidence surveys could be affected by inaccuracy of diagnosis and ascertainment, and prevalence also depends on survival. These sources of error might play a part in the geographical and temporal variations. Our literature search and meta-regression analyses indicated an almost universal increase in prevalence and incidence of MS over time; they challenge the well accepted theory of a latitudinal gradient of incidence of MS in Europe and North America, while this gradient is still apparent for Australia and New Zealand; and suggest a general, although not ubiquitous, increase in incidence of MS in females. The latter observation should prompt epidemiological studies to focus on changes in lifestyle in females. New insights into gene-environment and gene-gene interactions complicate interpretations of demographic epidemiology and have made obsolete the idea of simple causative associations between genes or the environment and MS.

Abstract
We conducted this study to determine familial Mediterranean fever (FMF)-associated central nervous system involvement including demyelinating lesions, stroke, and posterior reversible leukoencephalopathy syndrome (PRES). Patients with MEFV mutations were systematically reviewed through the Medical Biology Unit database. All samples sent for mutation analysis were screened for 10 common MEFV mutations. Patients with FMF and neurologic disorders according to the clinical records were invited for reevaluation. Lumbar puncture, electroencephalography, and evoked potentials were used to determine the type of neurologic involvement in selected cases. Electrocardiography, transthoracic and/or transesophageal echocardiography, and magnetic resonance imaging and/or angiography were performed to clarify the etiology of cerebrovascular disease. Of 8864 patients in the genetic testing database, 18 with neurologic signs were assessed. The mean age of patients was 31.0 +/- 11.8 years, mean age at first FMF symptom was 12.6 +/- 5.6 years, and mean age at neurologic involvement was 25.8 +/- 12.2 years. Fifty-five percent of patients were women. A homozygote MEFV mutation was detected in 16 of 18 patients (88.8%), and a homozygote M694V mutation was found in 72.2% of patients. We found 7 FMF patients with demyelinating lesions, 7 with cerebrovascular disease, and 4 with PRES. The mean interval between first FMF sign and neurologic involvement was 13.7 +/- 8.9 years in the demyelinating group, and 23.4 +/- 10.3 years in the group with cerebrovascular disease. Mean stroke age was 28.5 +/- 16.4 years. All patients in the PRES group had hypertension. Three different neurologic conditions in FMF patients were noticeable. Demyelinating lesions and cerebrovascular disease were the most common clinical presentations. Approximately 70% of patients had the homozygote M694V mutation. Neurologic involvement is rare but serious in FMF.

Abstract
Previous studies have estimated a prevalence of a broad grouping of autoimmune diseases of 3.2%, based on literature review of studies published between 1965 and 1995, and 5.3%, based on national hospitalization registry data in Denmark. We examine more recent studies pertaining to the prevalence of 29 autoimmune diseases, and use these data to correct for the underascertainment of some diseases in the hospitalization registry data. This analysis results in an estimated prevalence of 7.6-9.4%, depending on the size of the correction factor used. The rates for most diseases for which data are available from many geographic regions span overlapping ranges. We also review studies of the co-occurrence of diseases within individuals and within families, focusing on specific pairs of diseases to better distinguish patterns that may result in insights pertaining to shared etiological pathways. Overall, data support a tendency for autoimmune diseases to co-occur at greater than expected rates within proband patients and their families, but this does not appear to be a uniform phenomenon across all diseases. Multiple sclerosis and rheumatoid arthritis is one disease pair that appears to have a decreased chance of coexistence.

Abstract
BACKGROUND The frequency of multiple sclerosis (MS) in Greece remains speculative, as data from many parts are still lacking. OBJECTIVE To estimate trends in MS prevalence and annual incidence in western Greece from January 1, 1984 to December 31, 2006. METHODS Patients were identified from the patient records of the Department of Neurology at Patras University Hospital in Rion-Patras. Only patients with a definite MS diagnosis according to Poser's criteria and retrospective application of the McDonald's criteria were included. We calculated age- and sex-specific prevalence rates for patients living in the study area on December 31, 2006. Annual incidence rates were calculated for the period 1984-2006. RESULTS The crude prevalence rate of definite MS cases increased significantly in 23 years from 10.1/100,000 recorded in northeastern Greece in 1984 to 119.61/100,000 on December 31, 2006 in western Greece for the 780 cases still alive. The mean annual incidence rate increased from 2.71/100,000 recorded during the period 1984-1989 to 10.73/100,000 in the 5-year period of 2002-2006. CONCLUSION The prevalence rates were higher than expected, but closer than in previous surveys conducted in Greece to those reported recently in Sicily and Istanbul. These findings place the area in the high-risk zone.
