Preferences and perceptions of 617 migraine patients on acute and preventive migraine treatment attributes and clinical trial endpoints.

BACKGROUND: To identify the preferences and perceptions of migraine patients for acute and preventive treatment options and to investigate which treatment outcomes are the most important. DESIGN AND METHODS: The authors performed a choice-format survey in a cohort of migraine patients from Greece and Cyprus. A self-administered questionnaire developed in collaboration with the Greek Society of Migraine Patients was used. RESULTS: Questionnaires were collected from 617 migraine patients. Efficacy was preferred over safety as the single most important parameter, both in acute and preventive treatment. When analyzing single outcomes, patients prioritized a complete pain remission at 1-hour post-dose for acute therapies. Regarding migraine prevention, a 75% reduction in frequency, intensity of pain, accompanying symptoms and acute medication intake were considered as most important. Conversely, outcomes routinely used in clinical trials, namely complete or partial pain remission at 2-hours post-dose for acute treatment and 50% or 30% reduction in migraine frequency for prevention, were not deemed particularly relevant. Tablet formulation was mostly preferred, both in acute and preventive treatment. Conclusion: Listening to patients' needs may add a piece of the puzzle that is generally missing in clinical practice and often explains the lack of adherence in both acute and preventative anti-migraine therapies.

Reporting Quality and Risk of Bias Analysis of Published RCTs Assessing Anti-CGRP Monoclonal Antibodies in Migraine Prophylaxis: A Systematic Review.

Objective: Phase II/III randomized clinical trials (RCTs) are vulnerable to many types of bias beyond randomization. Insights into the reporting quality of RCTs involving migraine patients treated with monoclonal antibodies targeting the calcitonin gene-related peptide system (anti-CGRP MAbs) are currently lacking. Our aim was to analyze the reporting quality of phase II/III RCTs involving migraine patients treated with anti-CGRP MAbs. Methods: A systematic search was performed on the PubMed and EMBASE databases, according to PRISMA guidelines, for relevant RCTs in either episodic or chronic migraine prevention. Additionally, an adapted version of the 2010 CONSORT statement checklist was utilized. The ROBvis online tool was used to document the risk of bias. Results: From the initially identified 179 articles, we finally found 31 RCTs that were eligible for evaluation. The average CONSORT compliance was 88.7% (69.7-100%), while 93.5% (N = 29) of the articles had a compliance greater than 75%. Twenty-eight CONSORT items were reported in more than 75% of the articles. The average compliance of the analyzed RCTs was 93.9% for Galcanezumab, 91.3% for Fremanezumab, followed by 85.4% for Erenumab and Eptinezumab studies. Implementation of the ROB2 tool showed some concerning "missing information" arising from the inadequate reporting. Specifically, 50% of the studies (N = 16) were categorized as having inadequate information regarding the randomization process. Conclusions: Adequate reporting quality was disclosed in the evaluated RCTs with anti-CGRP MAbs in migraine prevention. However, some methodological issues need to be highlighted to be addressed in future studies assessing the efficacy of new molecules targeting CGRP or other candidate pathways implicated in migraine pathophysiology.

Mental illness through the perspective of undergraduate medical students in Greece: a cross-sectional study at Aristotle University of Thessaloniki.

Introduction: Numerous studies reveal that mental health-related stigma, stereotypes, and prejudices negatively affect the patients, jeopardizing their health, prognosis, and social opportunities. Healthcare professionals, who are in the first line of combating mental disease, are expected to play a significant role in drastically changing discriminatory and stigmatizing attitudes toward psychiatric patients and in diminishing the existing healthcare and social disparities. In this study, we aimed to explore and highlight the views of Greek medical students-that is of the future physicians-toward mental illness and people suffering from it. Materials and methods: It is a cross-sectional, observational study, in which 324 undergraduate students from the most populous Greek medical school of the Aristotle University of Thessaloniki, participated online, during the spring semester of 2022. The tools used were the Opinions about Mental Illness Scale (OMI) that assesses one's viewpoints about mental illness, the Social Distance Scale (SDS) that captures the desired degree of social distancing from patients with mental disorders, and the Level of Contact Report (LCR-12) that estimates the level of familiarity with them. Results: Participants displayed rather positive attitudes regarding the etiology of mental illness, social integration, and discrimination toward psychiatric patients [as evaluated with the respective OMI subscales; Etiology mean score (µ):8.87 ± 4.68, Social Integration (µ):17.79 ± 5.42, Social Discrimination (µ):13.54 ± 11.17], and more clearly favorable opinions concerning the need for social provision or the enactment of restrictive measures [as expressed with the relative OMI subscales; Social Care (µ):22.74 ± 4.56, Social Restriction (µ):13.27 ± 8.98], while claiming to be quite familiar with mental disorders and individuals experiencing them (as assessed with LCR; µ: 8.71 ± 2.16), and relatively willing to interact with them (as measured with SDS; µ:8.95 ± 4.23). Degree of familiarity with mental illness was directly proportional to the desire for contact with patients living with it, while the higher both were, the more improved most of the aforementioned OMI sectors were found to be. Female sex, clinical medical education, previous clinical psychiatric training, and living with or being a person with a mental disorder were the factors that defined a statistically refined profile in many of the aspects above. Conclusion: Our findings are in accordance with many prior and recent studies, while showing improved opinions compared to those of previous research in Greek student and healthcare population. They are calling for vigilance, rather than complacency, as well as educational and social interventions, in order to enable current and future healthcare professionals to perform their function to its fullest extent. Implications of our results and further research suggestions are included.

The prevalence and burden of medication overuse headache in Greece.

OBJECTIVE: To estimate the prevalence and burden of medication overuse headache in a representative sample of the Greek population, aged 18-70 years old. METHODS: This is a cross-sectional descriptive observational study performed by quantitative computer-assisted telephone interviews, using a standardized 37-item questionnaire for headaches. The prevalence of medication overuse headache was estimated in the general population and compared within the groups formed by factors such as age, gender, diagnosis of headache type, prophylactic treatment used, geographical regions, social class, workdays lost and loss of productivity. RESULTS: 1197 (12.0%) participants reported headaches affecting performance out of 10,008 interviewees. The estimated prevalence of medication overuse headache in the general population was 0.7% (95% CI: 0.5-0.9). The female to male ratio was 3.6:1. The proportion of medication overuse headache was largest in the 35-54 age group, followed by the over 55 group. The Aegean islands and Crete were the regions with the highest proportion of medication overuse headache. Among participants with headaches, the proportion of medication overuse headache was 5.8% (95% CI: 4.4%-7.1%); 6.3% (95% CI: 4.7%-7.9%) among females and 4.4% (95% CI: 2.2%-6.6%) among males. In the same headache group, the proportion of medication overuse headache by prophylactic treatment for headache was 19.0% (95% CI: 9.5%-29.1%) for recipients and 5.0% (95% CI: 3.8-6.3) for non-recipients. The mean absenteeism in people with medication overuse headache was 1.0 days/month (95% CI: 0.4-1.6) and the mean presenteeism 6.3 days/month (95% CI: 3.9-8.7). The social class stratification showed a significant effect between the medication overuse headache in the sample of the general population and the C2 class, corresponding to skilled manual labour (OR: 0.7, CI: 0.5-0.9). In people with chronic migraine, and chronic tension type headache, as differentiated by the 37-item questionnaire, the proportion of medication overuse headache in the headache group estimated to be 50.5% (95% CI: 40.8%-60.1%) and 45.9%, (95% CI: 29.9%-62.0%) respectively. The group of people with acute headache medication overuse fulfilling the rest of the diagnostic criteria for medication overuse headache, except from the number of headache days per month (≥15 days/month), had a prevalence of 2.0% (95% CI: 1.75-2.30) and a proportion of 17.0% (95% CI: 14.8%-19.1%) among people with headache. In the episodic types of headache, the proportion of acute headache medication overuse was higher in the subgroup of people with high frequency episodic migraine, 24.9% (95% CI: 18.8%-31.0%), while it was 10.8% (95% CI: 8.2%-13.5%), for the low frequency episodic migraine and 8.5% (95% CI: 5.5%-10.4%), for the episodic tension type headache. CONCLUSION: The prevalence of medication overuse headache in the general population in Greece and its proportion among the people with headache belongs to the lower part of the range of the reported literature, while the 3.6:1 female to male ratio is in agreement with it. In the same line, the impact of absenteeism and presenteeism on the workplace renders the condition alarming socio-economic health problem demanding immediate health policy planning.

Mental health-related stigma discrimination and prejudices among Greek healthcare professionals.

Introduction: Research shows that mental health-related stigma, stereotypes, and prejudices have a negative impact on the patients themselves as well as on their families and social entourage. Healthcare professionals, whose expertise and professional ethos are historically acknowledged by public opinion, are expected to play a major role in combating discrimination against psychiatric patients. In this study, we aimed to assess the attitudes of Greek healthcare professionals toward mental illness and people suffering from it. Materials and methods: It is a non-interventional, analytic study, in which 479 health workers from a tertiary hospital in Thessaloniki, Greece, participated. Every single hospital service -except the personnel of the Psychiatric Clinic- was included in our study: from the cleaning service to the administrative staff and the auxiliary staff such as stretcher carriers, food and nutrition services' staff, and social workers, the nursing staff, and finally the attending physicians, taking into consideration that the psychiatric patient, from the moment he/she enters the hospital, consecutively gets in contact with every work grade of the healthcare establishment. Participants' attitudes concerning mental illness have been evaluated using the Opinions about Mental Illness Scale (OMI), the Social Distance Scale (SDS), and the Level of Contact Report (LCR-12). Results: Despite the high level of familiarity [as evaluated with LCR-12; mean score (µ): 8.82 ± 1.73], the employees displayed a rather poor willingness to interact with psychiatric patients (as measured with SDS; µ:11.68 ± 4.28), and endorsed significant prejudice toward individuals with mental disorders (assessed using OMI subscales; Social Discrimination µ: 22.99 ± 12.08, Social Restriction µ: 17.45 ± 9.07, Social Care µ: 21.04 ± 4.12, Social Integration µ: 16.38 ± 4.68, Etiology µ: 9.80 ± 4.95). Age and education stood out as the main determinants of participants' attitudes, with younger and highly educated participants to have shown a relatively refined profile. Conclusion: These results are not significantly improved compared to those of previous decades in Greek healthcare professionals and call for critical reflection and targeted stigma-reduction efforts.

Excessive supraventricular ectopic activity and future onset of atrial fibrillation in patients with cryptogenic stroke.

OBJECTIVES: Although evidence has shown the association of excessive supraventricular ectopic activity (ESVEA) with future development of atrial fibrillation (AF), this relationship is not yet fully understood. This study examines whether ESVEA can predict the future onset of AF, in patients presenting with cryptogenic stroke. MATERIALS AND METHODS: A retrospective cohort of 124 non-AF, consecutive patients, hospitalized for cryptogenic stroke between 2014 and 2015, was retrieved. 24-h inpatient monitoring with Holter was employed to reveal ESVEA, defined as the presence of more than 20 premature atrial complexes per hour (PACs/h) on average, or a more than 5 s duration of the longest supraventricular run (LSVR). After a median follow-up period of 5.2 years, the patients were examined for AF. RESULTS: From initial 124 patients, 12 died and one was lost during follow-up. For the total of 111 patients finally included, the median age was 56 years and 25.2% were females. The overall baseline median CHA2DS2-VASc score was 3. AF was found in 13 (11.71%) patients. Patients who were finally diagnosed with AF had a significantly higher number of PACs/h and a longer median LSVR duration at baseline (16.67 vs. 0.21, p < 0.001 and 3 vs. 0 s, p < 0.001, respectively). The presence of ESVEA was also significantly more frequent among AF patients (46.15%, 95%CI: 17.78%-74.22%) compared to non-AF ones (6.1%, 95%CI: 1.3%-10.7%, p < 0.001). CONCLUSIONS: Excessive atrial ectopy, detected with 24 h inpatient Holter monitoring, is a significant indicator of future development of AF in patients presenting originally with a cryptogenic stroke.

Impact of Body Mass Index on the Age of Relapsing-Remitting Multiple Sclerosis Onset: A Retrospective Study.

A BACKROUND: Multiple sclerosis (MS) is a complex chronic disease of the central nervous system (CNS). Body mass index (BMI), a component of metabolic syndrome (MetS), is considered among the risk factors for MS. However, its role in MS remains ambiguous. OBJECTIVE: To examine the impact of BMI on the age of onset in patients with relapsing-remitting MS (RRMS) in a Greek cohort. METHODS: Data from 821 Greek patients with RRMS were collected. The BMI values were considered as quartiles. Comparisons for the demographic characteristics between the quartiles were made by Pearson's chi-square test for the categorical variables and by ANOVA for the continuous variables. An overall p-value was calculated corresponding to trend for association. In case of significant association, further post-hoc analysis was performed in order to identify differences in demographic characteristics between specific BMI quartiles groups. Linear regression analyses were used to assess the relationship between BMI and age at onset of MS. RESULTS: Comparisons of participant characteristics by quartiles of BMI revealed that participants with the highest BMI had an older age of disease onset. Results from linear regression analysis showed that with each increase of 1 BMI unit, the age of RRMS onset increases by 0.255 (95% CI 0.136 to 0.374) years, p < 0.001. CONCLUSIONS: Patients with higher BMI, as a parameter of MetS, exhibit increased age of RRMS onset. Our results may present an alternative personalized approach for diagnosis, prognosis, and/or prevention of RRMS.

A population-based survey for disabling headaches in Greece: Prevalence, burden and treatment preferences.

OBJECTIVE: To estimate the prevalence, burden and current treatment of disabling primary headaches in a large sample of the Greek population aged 18-70 years old. METHODS: This is an observational descriptive study, with cross-sectional design performed by quantitative computer-assisted telephone interviews, using a validated 37-item questionnaire for headaches. The prevalence, burden, and current treatment of primary headaches (ICHD-3) were recorded along with participants' treatment preferences. RESULTS: Out of 10,008 interviewed participants, 1197 (12.0%) reported headaches affecting performance. The annual prevalence of migraine was 8.1% (95% confidence interval, 7.6-8.7, corresponding to 0.6 million Greeks), of chronic migraine 1.0% (95% confidence interval, 0.8-1.2, corresponding to 0.1 million), and of tension-type headache 3.8% (95% confidence interval, 3.4-4.2, corresponding to 0.3 million). The participants with headaches reported 0.5 headache-induced lost workdays per month (corresponding to 5.8 million lost workdays annually) and reductions in performance on 2.8 workdays per month (corresponding to 30.9 million workdays annually). In all, 43.4% of headache participants felt bad/ashamed because of headaches and 21.9% sought professional treatment, most often from a private neurologist. 83.8% of headache participants had never taken pharmacological prophylaxis, and only 5.5% were currently under preventative treatment. For both prophylactic and acute treatment, headache participants prefer oral medication to injection or stimulation devices. CONCLUSION: More than 10% of the Greek adult population up to 70 years old experience disabling headaches, causing a dramatic work loss. More than 80% of these have never taken pharmacological prophylaxis. Thus, enriching the quality of life of people with headaches relies crucially on expanding awareness about headaches and their treatment.

Intravenous thrombolysis for acute ischemic stroke in Greece: the Safe Implementation of Thrombolysis in Stroke registry 15-year experience.

BACKGROUND: Intravenous thrombolysis (IVT) remains the only approved systemic reperfusion treatment for acute ischemic stroke (AIS), however there are scarce data regarding outcomes and complications of IVT in Greece. We evaluated safety and efficacy outcomes of IVT for AIS in Greece using the Safe Implementation of Thrombolysis in Stroke: International Stroke Thrombolysis Register (SITS-ISTR) dataset. METHODS: All AIS patients treated with IVT in Greece between December 2002 and July 2017 and recorded in the SITS-ISTR were evaluated. Demographics, risk factors, baseline stroke severity [defined using National Institutes of Health Stroke Scale (NIHSS)], and onset-to-treatment time (OTT) were recorded. Safety outcomes included symptomatic intracranial hemorrhage (sICH) and 3-month mortality rates. The efficacy outcomes evaluated a reduction in baseline NIHSS score at 2 and 24 h following IVT onset, 3-month favorable functional outcome [FFO; modified Rankin scale (mRS) scores of 0-1] and 3-month functional independence (FI; mRS-scores of 0-2). The safety and efficacy outcomes were assessed comparatively with previously published data from SITS national and international registries. RESULTS: A total of 523 AIS patients were treated with IVT in 12 Greek centers participating in the SITS-ISTR during the study period (mean age 62.4 ± 12.7; 34.6% women; median baseline NIHSS score: 11 points; median OTT: 150 min). The rates of sICH were 1.4%, 2.3%, and 3.8% according to the SIST-MOST, ECASS II, and NINDS criteria respectively. The median reduction in NIHSS score at 2 and 24 h was 3 [interquartile range (IQR): 1-5] and 5 (IQR: 2-8) points respectively. The 3-month FI, FFO and mortality were 66.5%, 55.6% and 7.9%. All safety and efficacy outcomes were comparable with available data from SITS-ISTR in other European countries. CONCLUSIONS: Our study underscores the safety and efficacy of IVT for AIS in Greece. Additional action is necessary in order to increase the availability of IVT in the Greek population and to include more centers in the SITS-ISTR.

Periodic Paralysis and Encephalopathy as Initial Manifestations of Graves' Disease: Case Report and Review of the Literature.

BACKGROUND: Thyrotoxic periodic paralysis (TPP) is an uncommon complication of Graves' disease, characterized by the triad of acute hypokalemia without total body potassium deficit, episodic muscle paralysis, and thyrotoxicosis. Graves' encephalopathy is an extremely rare form of encephalopathy associated with autoimmune thyroid disease (EAATD), characterized by neuropsychiatric symptoms, increased antithyroid antibodies and cerebrospinal fluid protein concentration, nonspecific electroencephalogram abnormalities, and cortico-responsiveness. Coexistence of both these complications in the same patient has not been reported before. CASE REPORT: We herein present a 48-year-old white male patient with TPP and encephalopathy as initial presentations of Graves' disease. Flaccid tetraparesis was reversed a few hours after potassium level correction and the patient did not suffer any relapse with the successful pharmaceutical management of the thyroid function. One month later, the patient presented with dizziness and behavioral symptoms, such as inappropriate laughter and anger. Brain magnetic resonance imaging revealed meningeal enhancement and cerebrospinal fluid analysis showed a mild protein increase, with a blood-brain barrier disruption. With the suspicion of EAATD, the patient was treated with high doses of corticosteroids and improved dramatically. CONCLUSIONS: To our knowledge this is the first reported coexistence of potentially treatable TPP and EAATD as initial neurological manifestations of Graves' disease, thereby underscoring the necessity of suspicion of possible underlying Graves' disease in patients with acute paralysis and encephalopathy of unclear origin.

Safety of Statin Pretreatment in Intravenous Thrombolysis for Acute Ischemic Stroke.

BACKGROUND AND PURPOSE: A recent meta-analysis investigating the association between statins and early outcomes in acute ischemic stroke (AIS) patients treated with intravenous thrombolysis (IVT) indicated that prestroke statin treatment was associated with increased risk of 90-day mortality and symptomatic intracranial hemorrhage. We investigated the potential association of statin pretreatment with early outcomes in a large, international registry of AIS patients treated with IVT. METHODS: We analyzed prospectively collected data from the Safe Implementation of Treatments in Stroke-East registry (SITS-EAST) registry on consecutive AIS patients treated with IVT during an 8-year period. Early clinical recovery within 24 hours was defined as reduction in baseline National Institutes of Health Stroke Scale score of ≥10 points. Favorable functional outcome at 3 months was defined as modified Rankin Scale scores of 0 to 1. Symptomatic intracranial hemorrhage was diagnosed using National Institute of Neurological Disorders and Stroke, European-Australasian Acute Stroke Study-II and SITS definitions. RESULTS: A total of 1660 AIS patients treated with IVT fulfilled our inclusion criteria. Patients with statin pretreatment (23%) had higher baseline stroke severity compared with cases who had not received any statin at symptom onset. After adjusting for potential confounders, statin pretreatment was not associated with a higher likelihood of symptomatic intracranial hemorrhage defined by any of the 3 definitions. Statin pretreatment was not related to 3-month all-cause mortality (odds ratio, 0.92; 95% confidence interval, 0.57-1.49; P=0.741) or 3-month favorable functional outcome (odds ratio, 0.81; 95% confidence interval, 0.52-1.27; P=0.364). Statin pretreatment was independently associated with a higher odds of early clinical recovery (odds ratio, 1.91; 95% confidence interval, 1.25-2.92; P=0.003). CONCLUSIONS: Statin pretreatment seems not to be associated with adverse outcomes in AIS patients treated with IVT. The effect of statin pretreatment on early functional outcomes in thrombolysed AIS patients deserves further investigation.

Impaired executive functioning after left anterior insular stroke: a case report.

Given the insular's anatomic complexity and functional interconnectivity, acute lesions may result in varied clinical presentations, including autonomic, somatosensory, perceptual, motor, affective, and cognitive deficits. Although functional neuroimaging studies have demonstrated its role in executive functions, no clinical manifestations have been reported to date. We present the case of a woman with an acute left anterior insular infarction leading to executive (i.e., word and design fluency, mental flexibility, sustained attention, inhibitory control), but not language, visuoperceptual, or memory impairment. This case confirms the left anterior insula's involvement in executive functioning and suggests that an infarction may result in executive impairment.

Subclinical central nervous system involvement and thrombophilic status in young thalassemia intermedia patients of Greek origin.

Beta thalassemia is known to be characterized by a hypercoagulable state, with prothrombotic factors present and thrombotic event development in a number of patients. The aim of the present study was to evaluate subclinical involvement of the central nervous system (CNS) in young patients with thalassemia intermedia, the use of nonimaging, noninvasive laboratory methods for detecting relevant abnormalities, and the frequency and possible correlation of coagulation abnormalities with CNS lesions. In this cross-sectional study, 24 young patients with thalassemia intermedia were evaluated (mean age 12 ± 4.6 years, range 4.5-20 years). Patients underwent neurological examination, inherited and acquired coagulation defect testing, as well as neurophysiologic and neuroimaging evaluation. Patients aged 6-16 also had intelligence scores measured. With regards to coagulation, a decrease in antithrombin III (ATIII), protein C and protein S activity was found in 4.1, 54.16 and 45.8% of patients, respectively. Increased D-dimers, as well as thrombin-antithrombin complex (TAT) and prothrombin fragment (F1 + 2) values were found in 12.5, 62.5 and 8.33% of patients, respectively. Heterozygosity and homozygosity for the methylenetetrahydrofolate reductase mutation was found in 45.8 and 12.5% of patients, whereas heterozygosity for factor V Leiden and G20210FII was found in 8.33 and 12.5% of patients, respectively, with increased prevalence compared to Greek population. Neuroimaging evaluation was normal in all patients. Neurophysiologic evaluation revealed abnormal findings in 33.3% of patients on electroencephalogram (EEG), 16% on brain auditory-evoked potentials (BAEPs) and 4.12% on somatosensory evoked potentials (SEPs). Visual-evoked potentials (VEPs) were normal in all patients. A statistically significant difference was found between low protein C values, as well as high platelet counts, with abnormal EEG findings (P = 0.004 and P = 0.039, respectively). Transcranial Doppler (TCD) measurements revealed increased peak systolic velocities in anterior and posterior cerebral arteries and in basilar artery in 57, 38 and 41% of patients, respectively, as compared to healthy population values. On the contrary, decreased mean velocities were found both on middle cerebral artery and pars terminalis of internal carotid examination in 28.5% of patients. Patients with pathological findings on TCD study had lower hematocrit (P = 0.049) and younger age (P = 0.001) than patients with normal measurements. With regards to intelligence scores, mean intelligence quotient (IQ) was 100 ± 19.1, with 11.7% of patients demonstrating IQ below 85. The study results confirm the early presence of hemostatic changes in patients with thalassemia intermedia. Additionally, they demonstrate subclinical CNS involvement starting at childhood. For such involvement detection, in addition to neuroimaging, neurophysiological and neuropsychological evaluation is warranted.

Long-term lack of progression after initial treatment of idiopathic hypertrophic pachymeningitis.

Idiopathic hypertrophic cranial pachymeningitis (IHCP) is a rare inflammatory disease which is sometimes difficult to diagnose and can lead to misinterpretations of the clinical and imaging findings. The main clinical manifestations are headache, ataxia and cranial nerve palsy. In most of the reported patients continuous medication is needed to avoid disease recurrence. We present a female patient with an 8-year follow-up, no clinical regression and no need for any further medical treatment. Even though most patients with IHCP experience recurrence after diagnosis and initial treatment there were no clinical or imaging signs of relapse in our patient. Our patient is still not under any medical or surgical treatment due to the lack of any significant symptoms.

Familial prevalence of autoimmune disorders in multiple sclerosis in Northern Greece.

OBJECTIVE: The objective of this study was to evaluate for up to 7 years the prevalence of autoimmune disorders among naïve (untreated) multiple sclerosis family members compared with a contemporary general control population in Northern Greece, in a prospective case-control study, and to examine the possible relationship between immunomodulatory treatment and the appearance of additional autoimmune disorders. METHODS: The patients and controls enrolled comprised 1383 patients with definite MS and 4392 relatives in their families and a total of 452 controls families with 1652 members. RESULTS: At baseline, 891 multiple sclerosis families with 3112 members (73 multiplex multiple sclerosis families with 292 members and 818 simplex families with 2820 members) and 355 control families with 1580 members were examined regarding whether they had any of 12 autoimmune diseases. The baseline affected multiplex plus simplex multiple sclerosis families, the family members and the coexistent additional autoimmune disorders were higher compared with controls. There was an increase in longitudinally affected multiple sclerosis families, multiple sclerosis family members and coexistent additional autoimmune disorders compared with respective findings at the baseline observation. Comparison analysis between two time point observations (after a mean 7.1 +/- 2.2 years) for each autoimmune disorder in overall multiple sclerosis family members revealed increased rates for longitudinal autoimmune Hashimoto's thyroiditis, Graves' disease, insulin-dependent diabetes mellitus, psoriasis and vitiligo (p = 0.02, p = 0.006, p = 0.0004, p = 0.05, and p = 0.05, respectively). Some 145 newly developed, longitudinally definite autoimmune cases were recognized in multiplex plus simplex multiple sclerosis families; 116 (80%) of these disorders were observed in patients with multiple sclerosis treated with immunomodulatory medications, and 68 of these 116 (58.6%) cases exhibited baseline positive autoreactive antibodies. Binary logistic regression analysis revealed that immunotherapy predisposes to autoimmunity (odds ratio 2.8, p < 0.001) independently of the presence of baseline autoantibodies and patients' gender. CONCLUSIONS: There is a longitudinally increased frequency of additional autoimmune disorders among multiple sclerosis family members, probably related to immunomodulatory therapy.

Workload of the emergency room neurologists and the neurological inpatient department in a Greek tertiary care hospital.

BACKGROUND: Data concerning the number of patients presenting to the emergency room (ER) and the workload in the departments in the European Union countries are scarce. In contrast to most European practice, Greek public hospitals in cities with more than one public health facilities are on-call not on a daily, but on a rotational basis. Exact data from Greece on the number of patients referred to the ER or the number of patients admitted to regular inpatient departments of the public hospitals under these conditions is lacking. PATIENTS AND METHODS: From February 1st, 2006 to January 31st, 2007, we performed an open prospective study on the workload at the ER as well as the inpatient department of the Neurological Clinic of Papageorgiou General Hospital in Thessaloniki, Greece. In addition, we performed an analysis of the number of inpatient admission to the Department of Neurology per trimester from January 1st, 2002 until March 31st, 2008. RESULTS: During the study period, a total of 5901 patients required neurological examination in the ER (8.75% of all ER patients). In parallel, 2054 patients were admitted to the neurological ward for hospitalization exceeding 24h with a mean hospitalization of 3.95 days. CONCLUSION: These data suggest that the workload of a tertiary care neurological in- and outpatient department is large. More research is needed to determine the impact this has on patient outcomes.

Headache patients in the emergency department of a Greek tertiary care hospital.

The aim of this study was to record the demographic and epidemiological data on adult patients with headache who attend the emergency department (ED) and the diagnoses that made by the neurologists in the ED of a tertiary care hospital in metropolitan Thessaloniki (Greece). In an open prospective study, demographic and epidemiological data were collected on all patients who reported headache (as chief complaint or not) and presented to the ED of Papageorgiou Hospital between August 2007 and July 2008. Headache patients accounted for 1.3% of all ED patients and for 15.5% of patients primarily referred to the ED neurologist. Tension type headache was the most frequent diagnosis, followed by secondary headaches and migraine. The large number of patients without final ED diagnosis and ward admission for further evaluation sheds a light on the immense workload of Greek ED physicians. Furthermore, we found evidence for the misuse of Emergency Medical Services by chronic headache patients. These findings indicate shortcomings in the pre-hospital (primary care) management of headache patients in the Greek National Health System to an extent unreported so far.
