Prevalence rate and influencing factors of restless leg syndrome in maintenance hemodialysis patients in Anhui province / 中华肾脏病杂志

Objective:To explore the prevalence rate of restless leg syndrome (RLS) and its related influencing factors in patients with maintenance hemodialysis (MHD) in Anhui province.Methods:It was a cross-sectional study, including regular MHD patients in blood purification centers of 27 hospitals in southern, central and northern Anhui province from January to March 2020. The investigation included general demographic characteristics, primary diseases, complications, dialysis-related conditions and drug use. According to the presence or absence of RLS, the patients were divided into RLS group and non-RLS group, and the differences of clinical data between the two groups were compared. Logistic regression analysis method was used to analyze the influencing factors of RLS.Results:The study included 3 025 MHD patients, aged (54.8±12.8) years old, with 1 819 males (60.1%) and 1 206 females (39.9%). The dialysis age was (5.5±3.8) years. The prevalence rates of RLS in MHD patients were 8.8% (265/3 025), of which 13.7% (77/561), 7.7% (88/1 145) and 7.6% (100/1 319) in southern, central and northern Anhui province, respectively. The prevalence rates of RLS in MHD patients in secondary and tertiary hospitals were 9.5% (55/577) and 8.6% (210/2 448), respectively. Proportion of hypertension, dialysis age, intact parathyroid hormone, alkaline phosphatase, 25(OH)D3, and proportions of secondary hyperparathyroidism, erythropoietin use, iron supplements, active vitamin D use, calcimimetic use, dialysis blood flow <250 ml/min and low-flux dialyzers in RLS group were higher than those in non-RLS group, while hemoglobin level and proportions of non-calcium-phosphorus binders and high-flux dialyzers were lower than those in non-RLS group (all P<0.05). Multivariate logistic regression analysis results showed that long dialysis age ( OR=1.188, 95% CI 1.031-1.369, P=0.017) and high alkaline phosphatase ( OR=1.007, 95% CI 1.001-1.013, P=0.047) were correlated with a higher risk of RLS in MHD patients. Conclusions:The prevalence rate of RLS in MHD patients in Anhui province is 8.8%. The prevalence rates of RLS in MHD patients in southern, central and northern Anhui province are 13.7%, 7.7% and 7.6%, respectively. The prevalence rate of RLS in secondary and tertiary hospitals are 9.5% and 8.6%, respectively. Long dialysis age and high alkaline phosphatase are associated with a high risk of RLS in MHD patients.

Sleep disorders in multiple sclerosis: a case-control study using the São Paulo Epidemiologic sleep study (Episono) database / Alterações de sono em esclerose múltipla: um estudo caso-controle utilizando o banco de dados do São Paulo Epidemiologic Sleep Study (Episono)

Abstract Background Sleep disorders such as obstructive sleep apnea and restless legs syndrome are prevalent in the general population and patients with chronic diseases such as multiple sclerosis (MS). Objectives This study compared the prevalence of sleep disorders complaints, fatigue, depression, and chronotype of adult patients with multiple sclerosis (PwMS) to a representative sample of São Paulo city residents. Methods A comparative study was made between PwMS and volunteers from the São Paulo Epidemiologic Sleep Study (Episono) study. We compared the scores of sleep questionnaires using the multivariate analysis of variance (MANOVA) test to evaluate the effects and analysis of variance (ANOVA) as a follow-up test. Covariates were age, sex, and physical activity. The Pearson correlation test was performed to measure the correlation between Expanded Disability Status Scale (EDSS) and the scores of the sleep questionnaires. Finally, we applied propensity score matching to reduce bias in estimating differences between the two groups. Analyses were performed using Stata 14 (StataCorp, College Station, TX, USA) and IBM SPSS Statistics for Windows version 22.0 (IBM Corp., Armonk, NY, USA). Results The Episono group had worse sleep quality, and more excessive daytime sleepiness than PwMS. Obstructive sleep apnea and restless legs syndrome were more frequent in the Episono group. There was no difference in chronotype between the two groups, with morning and intermediate preference. There was no correlation between EDSS and sleep complaints. Fatigue was intensively present among PwMS. Conclusions Disease Modifying Drug (DMD)-treated PwMS had a lower frequency of sleep complaints, no difference in chronotype, and a higher prevalence of fatigue than a sample of São Paulo city residents. The immunomodulatory drugs commonly used to treat MS may have contributed to these findings.

Resumo Antecedentes Os distúrbios do sono são prevalentes na população em geral e em pacientes com doenças crônicas, como a esclerose múltipla (EM). Objetivos No presente estudo, comparamos a prevalência de queixas de distúrbios do sono, fadiga, depressão e cronotipo de pacientes adultos com EM com uma amostra representativa dos moradores da cidade de São Paulo. Métodos Estudo comparativo entre pacientes com EM e voluntários saudáveis do estudo São Paulo Epidemiologic Sleep Study Episono. Comparamos as pontuações dos questionários de sono usando o teste de análise de variância multivariada (MANOVA, na sigla em inglês) para avaliar os efeitos e o teste de análise de variância (ANOVA, na sigla em inglês) como um teste de acompanhamento. As covariáveis usadas foram idade, gênero e atividade física. O teste de correlação de Pearson foi aplicado para medir a correlação entre o Expanded Disability Status Scale (EDSS) e os escores dos questionários de sono. Por fim, aplicamos o Propensity Score Matching para reduzir o viés na estimativa das diferenças entre os dois grupos. Resultados O grupo Episono apresentou pior qualidade do sono e mais sonolência excessiva diurna do que os pacientes com EM. A apneia obstrutiva do sono e a síndrome das pernas inquietas foram mais frequentes no grupo Episono. Não houve diferença no cronotipo entre os dois grupos, com predomínio matutino e intermediário. Os pacientes com EM apresentaram mais fadiga do que o grupo controle. Conclusões Pacientes com EM tratados apresentaram menor frequência de queixas de sono, sem diferença no cronotipo, com maior prevalência de fadiga do que uma amostra de moradores da cidade de São Paulo. Os medicamentos imunomoduladores comumente usados para tratar EM podem ter contribuído para estes achados.

Coexistence of restless legs syndrome and multiple sclerosis aggravates anxiety and depression / A coexistência da síndrome das pernas inquietas e esclerose múltipla agrava ansiedade e depressão

ABSTRACT Background: Among the comorbidities that accompany multiple sclerosis (MS), restless legs syndrome (RLS) is one of the most common. Anxiety and depression are common psychological comorbidities that impact the quality of life of patients with MS (PwMS), as well as patients with RLS. Objective: To investigate the psychiatric burden of MS and RLS coexistence, we conducted a nationwide, multicenter and cross-sectional survey. Methods: Participants were assessed by using demographic and clinical parameters along with the Hamilton Anxiety and Hamilton Depression Scales (HAM-A and HAM-D). Results: Out of the 1,068 participants, 173 (16.2%) were found to have RLS [RLS(+)] and 895 (83.8%) did not [RLS(-)]. The mean scores for HAM-A and HAM-D were significantly higher among RLS(+) subjects than among RLS(-) subjects (p<0.001 for all variables). Conclusions: According to our data, the presence of RLS in PwMS may increase the occurrence of both anxiety and depression symptoms. Awareness and treatment of RLS in PwMS could possibly reduce the symptoms of psychiatric comorbidities originating from RLS.

RESUMO Antecedentes: Considerando-se as comorbidades que acompanham a esclerose múltipla (EM), a síndrome das pernas inquietas (SPI) é uma das mais comuns, e ansiedade e depressão são comorbidades psicológicas comuns que afetam a qualidade de vida de pacientes com EM, bem como de pacientes com SPI. Objetivo: Investigar a carga psiquiátrica da coexistência de EM e SPI por meio de uma pesquisa nacional, multicêntrica e transversal. Métodos: Os participantes foram avaliados por parâmetros demográficos e clínicos, além da versão turca das escalas de ansiedade e depressão de Hamilton (HAM-A e HAM-D). Resultados: Dos 1.068 participantes, 173 (16,2%) apresentaram SPI [SPI (+)] e 895 (83,8%) não [SPI (-)]. As pontuações médias no HAM-A e no HAM-D foram significativamente maiores em indivíduos com SPI (+) do que naqueles com SPI (-) (p <0,001 para todas as variáveis). Conclusões: De acordo com nossos dados, a presença de SPI na EM pode aumentar a ocorrência de sintomas de ansiedade e depressão. A conscientização e o tratamento da SPI na EM podem reduzir os sintomas de comorbidades psiquiátricas originadas da SPI.

One case of Creutzfeldt-Jakob disease with restless leg syndrome as the first symptom and literature analysis / 中国基层医药

Objective:To analyze the clinical features and auxiliary examination results of sporadic Creutzfeldt-Jakob disease (sCJD) with restless leg syndrome (RLS) as the first symptom.Methods:The clinical features and auxiliary examination results of one case of sCJD who received treatment in Sichuan Mianyang 404 Hospital were analyzed based on relevant literature.Results:A 59-year-old woman of Han nationality who had sCJD with restless leg-like manifestation of the left lower limb for 18 days was included in this study. The patient was first treated in orthopedic department, but her symptom did not improve after treatment. Twenty days later, she was transferred to neurology department for further treatment. Her daily life and activities were not affected. Head magnetic resonance imaging, electroencephalography, cerebrospinal fluid routine examination and biochemical test results were normal. Five days later, the patient had mild left-sided ataxia, which then progressed rapidly, followed by right-sided ataxia, left-leg spasticity and adduction, involuntary movement, myoclonia, cognitive decline, akinetic mutism, repeated hyperthermia, repeated complex partial seizures. Two weeks later, head magnetic resonance imaging examination revealed hyperintense signal of the cingulate gyrus, frontal cortex and right island cortex on DWI, with cerebellar atrophy and three-phase electroencephalography wave. Four weeks later, CSF14-3-3 protein was positive, and no related genetic mutation in the prion protein gene was found. The duration from onset to death was about 8 months.Conclusion:sCJD is a common subtype of prion protein disease, and the condition can be stabilized for more than 1 month after the onset of RLS. There is no specificity in early clinical and auxiliary examinations, and neither dobutazine treatment nor neurotrophic treatment is effective. The disease progresses rapidly after 1 month, head MRI and EEG reexamination can reveal clues, and CSF14-3-3 protein can assist clinical diagnosis.

Is restless legs syndrome in Parkinson disease patients associated with any specific factor? / A síndrome das pernas inquietas nos pacientes com doença de Parkinson está associada a algum fator específico?

ABSTRACT Background: Restless legs syndrome or Willis-Ekbom disease is a disorder characterized by unpleasant sensations associated with the need to mobilize the lower limbs. In Parkinson disease patients, restless legs syndrome is associated with worse quality of life and excessive sleepiness. Regarding other factors, results of different studies are controversial. Objective: To determine the factors associated with the restless legs syndrome presence in Parkinson disease patients. Methods: A cross-sectional study was conducted in 88 consecutive Parkinson disease patients from the outpatient clinic for 21 months. Participants underwent a clinical interview, assessment based on standardized scales (Epworth Sleepiness Scale, Parkinson Disease Questionnaire - 39, Pittsburgh Sleep Quality Index, International Restless Legs Syndrome Study Group rating scale), and video-polysomnography. Results: Out of the 88 participants, 25 had restless legs syndrome. In the multivariate analysis, restless legs syndrome in Parkinson disease has been associated with the symptom of smell loss and quality of sleep and life. In the univariate analysis, restless legs syndrome in Parkinson disease has occurred more frequently in women with higher frequency of insomnia, constipation, and anosmia than in the group without restless legs syndrome. Conclusion: Restless legs syndrome is a prevalent condition in patients with Parkinson disease and is associated with specific characteristics in this group of patients.

RESUMO Introdução: A síndrome das pernas inquietas, ou doença de Willis-Ekbom, é um transtorno caracterizado por sensações de desconforto associadas à necessidade de movimentar os membros inferiores.

Em relação a outros fatores, resultados de diferentes estudos mostraram resultados controversos. Objetivo: Determinar os fatores associados à presença da síndrome das pernas inquietas nos pacientes com doença de Parkinson. Métodos: Um estudo transversal foi conduzido com 88 pacientes com doença de Parkinson, consecutivos, acompanhados em ambulatório especializado, durante 21 meses. Participantes passaram por uma entrevista clínica, avaliação por meio de escalas padronizadas (Escala de Sonolência de Epworth, Questionário de Qualidade de Vida da Doença de Parkinson, Índice de Qualidade de Sono de Pittsburgh, Escala de Gravidade Internacional da Síndrome das Pernas Inquietas) e videopolissonografia. Resultados: Do total de 88 participantes, 25 tinham síndrome das pernas inquietas. Na análise multivariada, a síndrome das pernas inquietas na doença de Parkinson esteve associada à perda de olfato, assim como à qualidade de vida e ao sono. Na análise univariada, a síndrome das pernas inquietas na doença de Parkinson ocorreu mais frequentemente em mulheres, com maior frequência de insônia, constipação e anosmia, do que no grupo sem síndrome das pernas inquietas. Conclusão: A síndrome das pernas inquietas é uma condição prevalente na doença de Parkinson e está associada a características específicas neste grupo de pacientes.

Research progress of single nucleotide polymorphisms of risk gene of restless legs syndrome / 中华神经科杂志

Restless legs syndrome (RLS) is a kind of common diseases of the nervous system, of which adult prevalence rate is from 1% to 15%. The etiology, pathogenesis and related gene therapy of RLS are not fully understood. Studies have shown that RLS may be associated with the polymorphism of some risk genes. Genome-wide association studies have revealed a total of seven risk sites to date, including MEIS1, BTBD9, MAP2K5/SKOR1, PTPRD, TOX3, NOS1 and 2p14 intergenic regions. This article reviewed the research progress of single nucleotide polymorphisms in RLS risk genes in recent years.

Accuracy of dexmedetomidine titration in diagnosis of restless legs syndrome / 中华麻醉学杂志

The medical records of patients of both sexes with sleep disorders treated with multimodal sleep therapy for which patient controlled sleep with dexmedetomidine was the main method, aged≥18 yr, with body mass index of 18-30 kg/m 2, from February 2019 to January 2021, were collected.Dexmedetomidine 60 ml/h (4 μg/ml) was intravenously infused until non-rapid eye movement (NREM) Ⅲ phase was reached or the consumption of dexmedetomidine reached 1 μg/kg.Whether dexmedetomidine induced restless legs syndrome (RLS) was judged according to the Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 edition). When the titration was stopped and on the next day after emergence from anesthesia, clinical diagnosis was performed according to Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 edition) to determine whether RLS was combined or not.Kappa consistency analysis was used to assess the consistency between dexmedetomidine titration and the Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 Edition) in diagnosis of RLS.The sensitivity and specificity of diagnosis of RLS by dexmedetomidine titration were calculated.A total of 39 patients were included and 8 patients had RLS symptoms which were judged accroding to dexmedetomidine titration.The results of Kappa consistency test showed that there was a strong consistency between dexmedetomidine titration and Chinese guidelines for the diagnosis and treatment of restless legs syndrome (2021 edition) (Kappa value 1.0, P<0.01). The sensitivity and specificity of dexmedetomidine titration in judging RLS were 100%.In conclusion, dexmedetomidine titration can accurately judge RLS.

Research progress on the mechanisms of restless legs syndrome in patients with Parkinson's disease / 中华老年医学杂志

Parkinson's disease(PD)and restless legs syndrome(RLS)are relatively common movement disorders.There has been much debate over whether an etiological link exists between these two diseases and whether they share common pathophysiological mechanisms.PD and RLS may co-occur and respond well to dopaminergic agents, suggesting there is underlying dopamine dysfunction in both conditions.Despite the overlapping clinical features, the mechanisms underlying idiopathic RLS and RLS associated with PD may differ.In this article, we review studies related to the epidemiology, pathophysiology and genetics of PD with concurrent RLS, in order to provide evidence for exploring the link between RLS and PD.

The effect of aerobic combined stretching exercise training on restless legs syndrome, quality of life in hemodialysis patients / 中国实用护理杂志

Objective:To investigate the effects of aerobic combined stretching exercise during dialysis on the severity of restless legs syndrome(RLS), quality of life and sleep quality in hemodialysis (HD) patients.Methods:A total of 63 HD patients with RLS who were admitted to the Hemodialysis Center, Renmin Hospital of Wuhan University from March 2018 to March 2019 were selected as research objects. According to the random number table method, they were divided into the observation group (32 cases) and the control group (31 cases). Patients in the control group were given conventional nursing methods while patients in the observation group were given the aerobic combined stretching exercise during dialysis. The International Restless Legs Syndrome Rating Scale (IRLS) Kidney Disease Quality of Life, (KDQOL-36 TM), Pittsburgh Sleep Quality Index(PSQI) and blood chemistry were used to evaluate the effect of exercise on HD patients with RLS. Results:After intervention, the observation group ′s IRLS scores was 12.19±4.48, lower than the control group (17.87±3.91), the difference was statistically significant ( t value was 3.021, P<0.05). The scores of physical health, mental health, kidney burden, symptoms and discomfort, effects of kidney disease in KDQOL-36 TM of the observation group were 44.56±6.64, 46.12±4.95, 19.92±15.91, 87.59±5.65, 64.55±13.20, higher than the control group (37.43±4.81, 41.81±4.87,12.10±14.87, 78.83±7.96, 55.45±15.52), the differences were statistically significant ( t values were -5.027--2.015, P<0.05). The PSQI total score was 8.94±2.54, lower than that of the control group (13.13±1.31), the difference was statistically significant ( t value was 8.271, P<0.05). The blood phosphorus was (1.80±0.48) mmol/L in the observation group, lower than (2.04±0.34) mmol/L in the control group, and hemoglobin, blood calcium [(105.31±13.58) g/L, (2.26±0.20) mg/L] were higher than those in the control group[(99.52±8.21) g/L, (2.05±0.29) mg/L], the differences were statistically significant ( t values were 2.275, -2.042, -3.325, P<0.05).

Sleep and restless legs syndrome in female adolescents with idiopathic musculoskeletal pain / Sono e síndrome das pernas inquietas em adolescentes do sexo feminino com dor musculoesquelética idiopática

Abstract Objectives: To assess the presence of restless legs syndrome, periodic leg movement, and sleep disorders in female adolescents with idiopathic musculoskeletal pain through a sleep scale and polysomnography, and to compare these data in adolescents without pain history. Method: Twenty-six adolescents diagnosed with idiopathic musculoskeletal pain followed in a pain outpatient clinic and 25 healthy controls matched by age and education were recruited. The restless legs syndrome criteria were evaluated according to the International Restless Legs Syndrome Study Group, the Sleep Disturbance Scale for Children was completed, nocturnal polysomnography was performed, and anxiety symptoms were recorded. Results: The mean age of idiopathic musculoskeletal pain adolescents was 13.9 ± 1.6 years; in controls, it was 14.4 ± 1.4 years. One adolescent in the control group (4 %) and nine patients with idiopathic musculoskeletal pain (34.6 %) fulfilled the restless legs syndrome criteria (p = 0.011). The authors did not observe significant differences in Sleep Disturbance Scale for Children scores between the groups in all components: disorders of initiating and maintaining sleep (p = 0.290), sleep breathing disorders (p = 0.576), disorders of arousal (p = 0.162), sleep-wake transition disorders (p = 0.258), disorder of excessive daytime somnolence (p = 0.594), and sleep hyperhidrosis (p = 0.797). The neurophysiological, respiratory, and periodic leg movement parameters were similar in both groups. Having anxiety was not associated with restless legs syndrome (p = 0.11). Three patients with idiopathic musculoskeletal pain (11.5 %) presented restless legs syndrome and periodic leg movement simultaneously, which was absent in the control group. Conclusion: Female adolescents with idiopathic musculoskeletal pain present criteria for RLS more frequently than healthy adolescents. However, this study did not observe relevant changes in objective and subject sleep variables.

Restless legs syndrome/Willis-Ekbom disease in multiple sclerosis: a contributing factor for anxiety, disability, sleep disorder, and quality of life / Síndrome de las piernas inquietas/enfermedad de Willis-Ekbom en la esclerosis múltiple: un factor que contribuye a la ansiedad, la discapacidad, los trastornos del sueño y la calidad de vida

ABSTRACT Background: Restless legs syndrome (RLS) is one of the most common and burdensome sleep disorders in the course of multiple sclerosis (MS). Objective: To evaluate common MS-related symptoms and consequences between groups with and without RLS and further assess the association of quality of life determinants with RLS symptom severity. Methods: According to their RLS status, 46 relapsing-remitting MS patients were divided into MS-RLS+ (n=19) and MS-RLS- groups (n=27). Specific questionnaires were administered to assess the patients' health-related quality of life (HRQoL), fatigue levels, sleep quality, daily sleepiness, anxiety, and depression symptoms. Functional capacity was examined using the Expanded Disability Status Scale (EDSS). Results: The prevalence of RLS was 41.3%. Compared to the MS-RLS- group, those with RLS had higher EDSS scores, more cranial and spinal lesions, longer disease duration, and were older. In the MS-RLS+ group, symptom severity scores were positively correlated with higher anxiety and poorer sleep quality. The symptom severity score was negatively correlated with mental HRQoL and pain scores. Conclusion: In conclusion, the findings of the current study indicate the negative impact of RLS on functional capacity, anxiety, sleep quality, and mental HRQoL of MS patients. Further studies using more accurate diagnostic strategies for identifying RLS and other sleep disorders are necessary to clarify the association of MS with RLS and explore relevant clinical implications.

RESUMEN Antecedentes: El síndrome de piernas inquietas (SPI) es uno de los trastornos del sueño más comunes y onerosos en el curso de la esclerosis múltiple (EM). Objetivo: El objetivo de este estudio fue evaluar los síntomas y las consecuencias comunes asociados con la EM entre los grupos con y sin SPI y evaluar aún más la asociación de los determinantes de la calidad de vida con la gravedad de los síntomas del SPI. Métodos: De acuerdo con su estado de SPI, 46 pacientes con EM recurrente-remitente se dividieron en los grupos EM-SPI+ (n=19) y EM-SPI- (n=27). Se utilizaron cuestionarios específicos para evaluar la calidad de vida relacionada con la salud (CVRS), los niveles de fatiga, la calidad del sueño, la somnolencia diaria, la ansiedad y los síntomas de depresión de los pacientes. La capacidad funcional se examinó mediante la escala ampliada del estado de discapacidad (Expanded Disability Status Scale — EDSS). Resultados: La prevalencia de SPI fue del 41,3%. Em comparación com el grupo EM-SPI-, aquellos com SPI tenían púntuaciones más altas em la EDSS, más lesiones craneales y espinales, mayor duración de la enfermedad y eran mayores. Los puntajes de gravedad de los síntomas em el grupo EM-SPI+ se correlacionaron positivamente con una mayor ansiedad y una peor calidad del sueño. Se observaron correlaciones negativas entre la puntuación de gravedad de los síntomas y la CVRS mental y los puntajes de dolor. Conclusiones: En conclusión, el estudio actual indica el impacto negativo del SPI en la discapacidad funcional, la ansiedad, la calidad del sueño y la CVRS mental de los pacientes con EM. Se necesitan más estudios que utilicen estrategias de diagnóstico más precisas para identificar el SPI y otros trastornos del sueño para aclarar la asociación de la EM con el SPI y para explorar implicaciones clínicas relevantes.

Analysis of YouTube as a source of information for restless leg syndrome / Análise do YouTube como fonte de informação para a síndrome das pernas inquietas

ABSTRACT Background: YouTube is one of the major resources for health related videos around the world. Objective: The aim of this study was to evaluate the quality of information available on YouTube about restless leg syndrome (RLS). Methods: A YouTube search was carried out on https://www.youtube.com for videos pertaining to "restless leg syndrome" by using the keyword "restless leg syndrome". The first 100 relevant videos were included in the study. The videos were accepted as "useful" if they provided scientifically correct information about any aspect of RLS. The videos containing scientifically unproven information are defined as "misleading". The overall quality of all videos was subjectively graded using the global quality scale (GQS), a 5-point Likert scale. Results: The median video length for the included videos was 3.39 (0.11-85) minutes, and the median views were 6,055 (32-2351490). The median GQS of useful videos was 3 (1-5). The median number of likes and the median number of comments of personal experience videos were significantly higher than that of the useful and misleading videos. Videos uploaded by the university hospitals frequently issued pharmacological treatment of the RLS; however, those uploaded by practitioners, individual users, and TV or social media accounts were about the non-pharmacological treatment of the RLS. Conclusions: This study demonstrates that 77% of the videos uploaded on YouTube regarding RLS are in the useful category, whereas only 16 videos were providing misleading information. However, even videos in the useful category do not provide a full and complete description of the RLS.

RESUMO Introdução: O YouTube é um dos principais recursos no mundo para vídeos relacionados à saúde. Objetivo: O objetivo deste estudo foi avaliar a qualidade das informações disponíveis no YouTube sobre a síndrome das pernas inquietas (SPI). Métodos: Realizou-se uma busca no YouTube (https://www.youtube.com) para vídeos pertencentes à 'síndrome das pernas inquietas' usando a palavra-chave 'síndrome das pernas inquietas'. Os primeiros 100 vídeos relevantes foram incluídos no estudo. Foram aceitos como 'úteis' vídeos que fornecessem informações cientificamente corretas sobre qualquer aspecto da SPI. Os vídeos que contêm informações não comprovadas cientificamente são definidos como 'enganosos'. A qualidade geral de todos os vídeos foi avaliada subjetivamente usando a escala de qualidade global (GQS), uma escala Likert de 5 pontos. Resultados: A duração média dos vídeos incluídos foi de 3,39 (0,11-85) minutos e as visualizações médias foram de 6.055 (32-2.351.490). A GQS média dos vídeos úteis foi 3 (1-5). O número médio de curtidas e o número médio de comentários de vídeos de experiências pessoais foram significativamente maiores do que os de vídeos úteis e enganosos. Vídeos enviados por hospitais universitários frequentemente divulgam tratamento farmacológico da SPI; no entanto, aqueles carregados por profissionais, usuários individuais e contas de TV ou mídia social eram sobre o tratamento não farmacológico da SPI. Conclusões: Este estudo demonstrou que 77% dos vídeos carregados no YouTube sobre a SPI estão na categoria útil, enquanto apenas 16 vídeos forneceram informações enganosas. No entanto, mesmo os vídeos na categoria útil não fornecem uma descrição extensa e completa da SPI.

Creating cartoons to represent habitual leg movements / Desenvolvimento de modelos iconográficos representativos de movimentos habituais de pernas

Abstract Many people have a habit of moving their legs and believe that this behavior is due to the restless legs syndrome (RLS), a highly prevalent neurological condition that greatly impairs the quality of life of affected individuals. This behavioral pattern, characterized by the habit of moving one's legs and feet, may be an important confounding factor in the diagnosis of RLS. Objective: To describe the main movements associated with this benign behavioral state to characterize a possible clinical condition that can contribute to the differential diagnosis of RLS. Methods: Experienced sleep specialists, who primarily see RLS patients listed the most frequent movements people without RLS report while describing their suspected RLS. We first compiled a list of the lower-limb movements described by the specialists. Then, one of the authors (KC) carried out all movements of the list on camera to obtain a video footage. This footage was sent to one of the authors, EPC, who, alongside a group of students, drew graphic representations (cartoons) of the recorded movements. Results: The panel of sleep experts described 13 leg movements commonly reported by their patients. The experts reported 11 simple movements and two combined movements. Conclusion: In this study we developed an instrument that allows us to oppose and distinguish a pathological condition (RLS) from a behavioral phenomenon. This state of behavioral leg fidgeting needs to be better characterized and may eventually be recognized as a clinical entity per se.

Resumo Muitas pessoas têm o hábito de movimentar as pernas e acreditam que esse comportamento decorre da Síndrome das Pernas Inquietas (SPI), uma condição neurológica altamente prevalente com grande impacto na qualidade de vida dos indivíduos acometidos. Esse padrão de comportamento, caracterizado pelo costume de mover as pernas e os pés, pode ser um importante fator confundidor no diagnóstico da SPI. Objetivo: Descrever os principais movimentos associados a esse estado comportamental benigno, com a finalidade de caracterizar uma eventual condição clínica que possa contribuir para o diagnóstico diferencial da SPI. Métodos: Especialistas em distúrbios do sono, que atendem principalmente pacientes com SPI, listaram os movimentos que as pessoas sem SPI reportam com maior frequência enquanto descrevem a sua suspeita de síndrome. Elaboramos uma lista de movimentos dos membros inferiores descritos pelos especialistas e um dos autores (KC) realizou esses movimentos para que fossem gravados em vídeo. Essa filmagem foi enviada ao autor EPC, que, em conjunto com um grupo de alunos, realizou a representação gráfica (cartoon) dos movimentos gravados. Resultados: Os especialistas reportaram 13 movimentos de pernas, sendo 11 movimentos simples e dois movimentos combinados. Conclusão: Neste estudo, elaboramos um instrumento que permite opor, com a finalidade de diferenciá-las, uma condição patológica (SPI) de um fenômeno comportamental. Esse estado de inquietude comportamental das pernas necessita ser mais bem caracterizado, podendo eventualmente vir a ser reconhecido como uma entidade clínica per se.

Restless Legs Syndrome, and symptoms of Restless Syndrome in patients with Graves disease: a cross-sectional survey

OBJECTIVES: Restless legs syndrome (RLS) is a frequent comorbid condition associated with distinct unrelated diseases. While the incidence of RLS has not been definitively confirmed, RLS-like symptoms have been reported in a section of Asian population who also had hyperthyroidism. The prevalence of RLS is generally low in Asian populations. Under these circumstances, we hypothesized that in a population where RLS is common, such as in Brazil, RLS could manifest as a comorbid ailment alongside Graves' disease, a common hyperthyroid condition. METHODS: In a cross-sectional survey, 108 patients who presented with Graves' disease were analyzed for restless legs or associated symptoms. RESULTS: Twelve patients (11.1%) displayed symptoms of RLS prior to the incidence of Graves' disease. These patients experienced worsening of the symptoms during their hyperthyroid state. Six patients (5.6%) developed RLS, consequent upon the incidence of Graves' disease as per the consensus of the panel of the experts. Fifteen patients (13.9%) also presented with RLS-like symptoms without any discernible circadian feature of the syndrome. CONCLUSION: Our findings confirm that Graves' disease might trigger restless legs-like symptoms, while the condition of hyperthyroidism could also be complicated by definite RLS.

Updates on the Diagnosis and Treatment of Restless Legs Syndrome / 신경정신의학

Restless legs syndrome (RLS) is a neurological sleep disorder characterized by an urge to move the legs or arms and is associated with discomfort and paresthesia in the legs. RLS is diagnosed based on the clinical symptoms, and polysomnography is performed to quantify the periodic limb movements during sleep or in patients who undergo the suggested immobilization test. Determining the cause of RLS is important for accurately diagnosing and evaluating this condition. The treatment of RLS varies according to the etiology, severity, and frequency of the patients' symptoms. Accurate identification and treatment of the cause of RLS are important in patients with secondary RLS. Iron supplementation could be useful in patients with uremia, iron deficiency, and for RLS during pregnancy. Dopamine agonists have been used as the first-line treatment for primary RLS. On the other hand, augmentation is a known adverse effect associated with the long-term use of dopamine agonists. Therefore, recent treatment guidelines recommend the administration of anticonvulsants, such as pregabalin and gabapentin, to treat RLS. Iron, opioids, or benzodiazepines may be useful in patients refractory to anticonvulsants or dopamine agonists. RLS is a chronic condition. Therefore, it is essential to establish a long-term treatment plan, considering both the efficacy and adverse effects of therapeutic agents used in patients.

Two Cases with Restless Legs Syndrome Successfully Treated with Kampo Medicine / 日本東洋医学雑誌

We report two cases with honton disease, also regarded as restless legs syndrome (RLS), successfully treated with a combination of goshuyuto and ryokeijutsukanto. Case 1 was an 88-year-old woman who started experiencing RLS after she received cardiac bypass graft when she was 76-years-old. Abdominal examination revealed stuck sensation in the pit of her stomach and aortic palpitation around the upper umbilical region. From these examination results as well as the deficiency pattern, cold pattern, qi deficiency, and qi stagnation, we diagnosed the case as a hontonto (Zhouhou fang) indication. A combination therapy of goshuyuto and ryokeijutsukanto was administered. Consequently, the stuck sensation and RLS disappeared. Meanwhile, Case 2 was a 62-year-old woman who experienced RLS upon going to bed after she underwent breast cancer surgery at the age of 54 years. Similarly, abdominal examination revealed stuck sensation in the pit of her stomach, aortic palpitation around the upper umbilical region, and lower abdominal numbness. These examination results as well as the slight deficiency pattern, upper heat and lower cold pattern, qi deficiency, and qi stagnation indicated hontonto (Zhouhou fang). The same combination therapy was given. Eventually, the stuck sensation disappeared, and the RLS was reduced. Therefore, for RLS that appears after a mental load with invasive therapy, the combination therapy of goshuyuto and ryokeijutsukanto may be an effective treatment choice.

Hierro intravenoso en la terapia del síndrome de piernas inquietas / Intravenous iron for restless legs syndrome. Report of five cases

Restless legs syndrome (RLS) may severely affect the quality of life of patients. A deficient iron incorporation into the central nervous system has an important role in the pathophysiology of RLS. Severely affected patients may not respond to current therapeutic options. We report a preliminary experience with five patients with severe RLS and low serum ferritin levels who did not improve with oral iron. All were treated with 1 g of intravenous iron carboxymaltose. They experienced a marked improvement in symptoms, evident even during the first week of therapy that had persistent after up to two years of follow-up. A significant change in the RLS severity scale was observed after intravenous iron. Serum ferritin levels increased in all of them. Intravenous iron could be a therapeutic option for patients with severe RLS.

Prevalence and risk factors of restless legs syndrome in patients of migraine without aura

Background: An association between migraine and Restless Legs Syndrome (RLS) has been proposed due to shared dopaminergic dysfunction. Both have substantial effects on the quality of life. Identifying co morbidities of migraine helps in optimizing patient management. Objectives To study the prevalence of RLS in patients of migraine without aura, and associated co morbidities of RLS.Methods: This was a hospital based prospective observational study. All patients diagnosed as Migraine without aura as per ICHD-3 criteria completed the questions regarding migraine headache, Migraine Disability Assessment (MIDAS) questionnaire, Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index (PSQI) and International RLS Study Group (IRLSSG) Rating Scale. RLS was diagnosed using the IRLSSG criteria. Serological investigations were done to look for secondary causes of RLS.Results: Out of 200 consecutive patients of migraine without aura were included in the study over a period of 18 months. Frequency of RLS was 13.5% (n=27). All patients had primary RLS. Mean PSQI score was higher in the patients of migraine without aura with RLS than in non RLS patients of migraine without aura (3.30±2.66 vs 2.24±2.03 p≤0.0168). Poor sleep quality, anxiety, depression was found in 9%, 8% and 2.5% respectively in patients of migraine without aura.Conclusions: An association between migraine without aura and RLS was demonstrated. Migraine without aura was associated with increased frequency of poor sleep quality, anxiety and depression.

Restless legs syndrome and quality of life in pregnant women

SUMMARY OBJECTIVE: In this study, we aimed to determine the extent of restless legs syndrome (RLS) in pregnant women and evaluate the relationship between the syndrome and quality of life. METHODS: This is a cross-sectional descriptive study. A questionnaire developed by the researcher, the Short Form 36 (SF-36) Questionnaire to measure the quality of life, the International Restless Legs Syndrome Study Group (IRLSSG) Diagnostic Criteria for RLS and the Restless Legs Syndrome Rating Scale were applied to the women to collect the data. A total of 250 pregnant women were included in the study. RESULTS: The mean age of the women was 28.11 ± 5.59 years and the mean gestational time was 26.26 ± 10.72 weeks. Symptoms of RLS were seen in 46.4 % of the women. The mean for the RLS Violence Rating Score was 20.82 ± 6.61 for the women with RLS. RLS was found to be mild in 5.2 % of the women, moderate in 45.7 %, severe in 40.5 % and very severe in 8.6 %. A statistically significant effect of RLS survival on quality of life was observed. CONCLUSION: These results indicate that almost half of the pregnant women in this study experienced RLS, and about half of those with RLS experienced severe or very severe RLS. There is a significant relationship between RLS and six domains of SF-36 (physical, role limitations, pain, general health perception, energy/vitality, and mental health).

RESUMO OBJETIVO: Neste estudo, objetivamos determinar a extensão da síndrome das pernas inquietas (SPI) em gestantes e avaliar a relação da síndrome com a qualidade de vida. MÉTODOS: Este é um estudo descritivo transversal. Um questionário desenvolvido pelo pesquisador, o Questionário Short Form 36 (SF-36) para medir a qualidade de vida, o Grupo Internacional de Síndrome das Pernas Inquietas (IRLSSG) Critérios de Diagnóstico para SPI e a Escala de Avaliação da Síndrome das Pernas Inquietas foram administrados às mulheres para coletar os dados. Um total de 250 gestantes foi incluído no estudo. RESULTADOS: A média de idade das mulheres foi de 28,11 ± 5,59 e a média das semanas gestacionais da gestação foi de 26,26 ± 10,72. Os sintomas da SPI foram observados em 46,4% das mulheres. A média para o Índice de Violência da RLS foi de 20,82 ± 6,61 para as mulheres com SPI. A SPI foi discreta em 5,2% das mulheres, moderada em 45,7%, grave em 40,5% e muito grave em 8,6%. Um efeito estatisticamente significativo da sobrevida da SPI na qualidade de vida foi observado (p<0,005). CONCLUSÃO: Estes resultados indicam que quase metade das mulheres grávidas neste estudo experimentou a SPI, e cerca de metade das pessoas com SPI experimentou SPI grave ou muito grave. Existe uma relação significativa entre a SPI e seis domínios do SF-36 (físico, limitação de papéis, dor, percepção geral de saúde, energia/vitalidade e saúde mental).
