Prevalence of Restless Legs Syndrome in Migraine Patients: A Case-Control Study. Analysis of Risk Factors for Restless Legs Syndrome in Migraine Patients.

BACKGROUND: Restless legs syndrome (RLS) is a sensorimotor disorder. It can be idiopathic, associated to other diseases or to pharmacologic treatments. RLS has been reported to occur more frequently in migraine patients, but a clear pathogenetic link seems still under debate. We aimed to evaluate RLS prevalence in migraine, impact on sleep quality and the main clinical determinants of this association. METHODS: Migraine patients and age- and sex-matched controls were enrolled from 1st January 2011 to 30th December 2012. Migraine and RLS diagnosis complied with already published clinical criteria. Medical and pharmacological histories, as well as structured questionnaires were collected. RESULTS: RLS was found in 29/180 (16.1%) patients and 11/180 (6.1%) controls. The odds ratio (OR) for RLS was 2.95 (CI 95%, 1.42-6.11). Among migraine patients, after adjustment for possible confounding factors, familial history (OR 3.863, CI 1.076-13.873), and serotoninergic overload (OR 3.654, CI 1.347-9.916) were significantly associated with RLS occurrence. Pittsburgh Sleep Quality Index score was higher in migraine patients with RLS than in subjects without RLS. CONCLUSIONS: The confirmed association between migraine and RLS might be because of familial predisposition and to serotoninergic drugs effect, possibly interfering with the balance between dopaminergic and serotoninergic pathways.

Identification of stroke etiology may contribute to improve the outcome in dedicated units.

BACKGROUND: The purpose of our study is to investigate whether stroke unit (SU) care and the utilization of Trial of ORG 10172 in Acute Stroke Treatment (TOAST) criteria may contribute to reduce death and disability in hospitalized patients after a first-ever ischemic stroke (IS). METHODS: Data included in the present study were derived from our previous study on the incidence and outcome of cerebrovascular diseases in the district of Udine, performed from April 1, 2007, to March 31, 2009. RESULTS: We identified 429 hospitalized first-ever IS cases, 297 of 429 (69.2%) patients were admitted to a dedicated SU and 132 of 429 (30.8%) to a general medical ward. According to the TOAST criteria, 101 of 132 first-ever ISs (76.5%) admitted to general medical wards were of undetermined (UND) etiology, whereas in only 105 of 297 (35.4%) patients admitted to the SU, the diagnosis remained UND. Multivariable analysis after propensity score matching showed that compared with general medical wards, SU care was associated with a reduced probability of being dead or highly disabled (P = .025) at the end of follow-up. Moreover, patients with an UND diagnosis had a worse 6-month case fatality (P < .0001) and also higher risk of being dead or highly disabled (P < .0001). CONCLUSIONS: Our study provides real-world evidence that accurate etiologic subtype classification of ISs according to TOAST criteria and SU care as opposed to general medical ward management are associated with reduction of the proportion of poor outcomes in first-ever IS patients.

Incidence of transient ischemic attack and early stroke risk: validation of the ABCD2 score in an Italian population-based study.

BACKGROUND AND PURPOSE: The importance of transient ischemic attack (TIA) lies on the short-term risk of stroke, and the ABCD2 score may improve early stroke risk prediction. However, population-based studies are still needed. We aimed to provide data on TIA incidence and to evaluate the ABCD2 predictive ability for early recurrent stroke in a population-based study. METHODS: This study is part of a 2-year prospective community-based registry of all cerebrovascular events in the district of Udine (153 312 inhabitants), Friuli Venezia Giulia region, northeast of Italy, between April 1, 2007 and March 31, 2009. Multiple overlapping sources for finding cases were used, combining hot and cold pursuit. RESULTS: We identified 178 TIA, 161 (90.4%) of which were incident. The crude overall annual TIA incidence rate per 1000 residents was 0.52 (95% confidence interval [CI], 0.45-0.61). Incidence rate was 0.45 (95% CI, 0.31-0.65) when standardized to the 2007 Italian population and 0.25 (95% CI, 0.16-0.39) when standardized to the European standard population. Estimates of stroke risk after the index TIA within 2, 7, 30, and 90 days were, respectively, 2.5% (95% CI, 0.7-6.2), 5.6% (95% CI, 2.6-10.3), 6.2% (95% CI, 3.0-11.1), and 11.2% (95% CI, 6.8-17.1). ABCD2 score was strongly associated with stroke occurrence after index TIA: the areas under the receiver operating characteristic curve at 2, 7, 30, and 90 days were, respectively, 0.85 (95% CI, 0.72-0.97), 0.69 (95% CI, 0.56-0.82), 0.69 (95% CI, 0.56-0.85), and 0.76 (95% CI, 0.67-0.86). No patients with an ABCD2 score <4 had a stroke within the 90-day follow-up period. CONCLUSIONS: This study adds new data on TIA incidence and prognosis and it further validates the ability of the ABCD2 score to identify patients at early risk for stroke.

Stroke incidence and 30-day and six-month case fatality rates in Udine, Italy: a population-based prospective study.

BACKGROUND: Stroke incidence in high-income countries is reported to decrease, and new data on stroke incidence and outcome are needed to design stroke services and to ameliorate stroke management. METHODS: This study is part of a two-year prospective community-based registry of all cerebrovascular events in the district of Udine (153,312 inhabitants), Friuli-Venezia Giulia region, northeast of Italy, between 1 April 2007 and 31 March 2009. Overlapping sources for case finding were used, combining hot and cold pursuit. RESULTS: We identified 784 stroke cases, 640 (81.6%) incident. The crude overall annual incidence rate per 100,000 residents was 256 (95% confidence interval 241-271) for all strokes and 209 (95% confidence interval 195-223) for first-ever strokes. Incidence rate for first-ever strokes was 181 (95% confidence interval 155-211) after adjustment to the 2007 Italian population and 104 (95% confidence interval 88-122) compared with the European standard population. Incidence rates for first-ever strokes was 215 (196-235) for women, 202 (183-223) for men. Crude annual incidence rates per 100,000 population were 167 (153-178) for ischemic stroke, 31 (26-37) for intracerebral hemorrhage, 8.1 (5.7-11.4) for sub-arachnoid hemorrhage, and 4.6 (2.8-7.1) for undetermined stroke. Overall case fatality rates for first-ever stroke were 20.6% at 28 days and 30.2% at 180 days. CONCLUSIONS: Our study shows incidence rates higher than previously reported in our region but not supporting the view of higher incidence rates in Northern than in Southern Italy. Results contribute to time-trends analysis on epidemiology, useful for dimensioning services in Italy and show the persistence of a gap between the outcome of stroke in Italy and that of the best performing European countries, urging to adopt better stroke management plans.
