Orophaxryngeal dysphagia in polymyositis/dermatomyositis

PubMed ID: 15567550The nature of the oropharyngeal dysphagia in polymyositis/dermatomyositis (PM/DM) has been investigated by EMG methods. Nineteen patients with PM/DM were studied. The oropharyngeal phase of swallowing was evaluated by the electrophysiological methods measuring the laryngeal relocation time, pharyngeal transit time and the triggering of the pharyngeal phase of swallowing reflex. The EMG of cricopharyngeal muscle of the upper esophageal sphincter was also recorded in 10 patients. The patients have been compared with a group of 22 healthy controls matched with age and gender. Dysphagia limit was also measured for all patients and control subjects. Fourteen out of 19 patients could not swallow 20 ml or less amount of water at one go and divided the bolus into two or more pieces (piecemeal deglutition) in comparison to normal subjects. In PM/DM patients, the triggering of the swallowing reflex for the voluntarily initiated swallow was normal while the pharyngeal phase of swallowing was significantly prolonged. The cricopharyngeal sphincter muscle EMG demonstrated severe abnormalities in halves of the patients investigated. These findings demonstrated the weakness of the striated oropharyngeal muscles. Cricopharyngeal sphincter muscle was affected less frequently and showed either hyperreflexic or hyporeflexic states during swallowing. It is concluded that the pharyngeal stage of oropharyngeal swallowing is mainly involved in patients with PM/DM. © 2004 Published by Elsevier B.V.This work has been supported by the Turkish Academy of Sciences in the framework of the Young Scientist Award Program.

Delayed encephalopathy of carbon monoxide intoxication and treatment with hyperbaric oxygen: A case report [Karbonmonoksit i·ntoksikasyonuna bagli{dotless} gecikmiş ensefalopati ve hiperbarik oksijen uygulamasi{dotless}: Olgu sunumu]

Delayed encephalopathy (DE) is a neuropsychiatric syndrome that can generally arise within 20 days of acute carbon monoxide (CO) intoxication after apparent recovery and involves variable degrees of cognitive deficits, personality changes, movement disorders and focal neurologic deficits. We report a 35-year-old female patient with delayed encephalopathy due to CO intoxication, presenting with cognitive impairment and mild parkinsonism despite receiving hyberbaric oxygen therapy (HBO). Magnetic resonance imaging (MRI) showed abnormal signal intensity and decreased diffusivity at both caudate nuclei and globus pallidus. She continued to receive additional HBO therapy and recovered completely within six months. The positive effects of early HBO therapy in selected patients on reversing the acute effects of CO intoxication is apparent. Here, we also review the beneficial effect of HBO in preventing or limiting the late neurocognitive deficits associated with severe CO intoxication

Overactive bladder symptoms in patients with multiple sclerosis: Frequency, severity, diagnosis and treatment

Objective: To determine the frequency and severity as well as the diagnosis and treatment of overactive bladder problems in patients with multiple sclerosis (MS) followed up at five centers in Turkey. Design: Survey study. Setting: Outpatient tertiary clinics of physical medicine and rehabilitation and neurology. Participants: Consecutive MS patients scheduled for outpatient follow-up (n= 309). Intervention: MS patients were asked to complete a questionnaire regarding the frequency and severity, as well as the diagnosis and treatment of their overactive bladder problems. Results: The mean age±SD was 39.3±10.6 years. Urinary urgency was the most common urinary symptom (62%), followed by frequency (50.4%), urge incontinence (44.7%) and nocturia (33%). Residual urine volume was measured using a portable ultrasound instrument in 13.3% of the patients and by catheterization in 16.2% of them. Urodynamic investigations and urinary tract ultrasound were performed on 26.5% and 35.3% of the patients, respectively. Anticholinergic medications were prescribed for 27.5% of the patients. Intermittent catheterization and indwelling catheterization were used on 8.1% and 1.9% of the patients, respectively. The overactive bladder symptom score (OABSS) was significantly higher in patients who had had residual urine measurement (P<0.001), upper urinary tract assessment by ultrasound (P<0.001), urodynamic assessment (P<0.001), admitted to a doctor for urinary symptoms (P<0.001), and current or past catheter use (P=0.002). Conclusion: Urgency was the most common urinary symptom followed by frequency, urge incontinence and nocturia in MS patients. The patients with lower OABSS had detailed urological assessments less frequently than the patients with higher OABSS. © The Academy of Spinal Cord Injury Professionals, Inc. 2015

‘Is RLS a harbinger and consequence of MS?: Striking results of the ‘RELOMS-T’ study’

PubMed: 324735752-s2.0-85085323057Background: Although studies report a high prevalence rate of restless legs syndrome (RLS) among patients with multiple sclerosis (PwMS) ranging from 13.3 to 65.1%, little is known about the causes of this relationship. Methods: To ascertain the prevalence, features and impact of RLS among PwMS a nation-wide, multicenter, prospective and a cross-sectional survey, designed to reflect all of the PwMS throughout Turkey, was conducted in 13 centers. Exploring the relationship of the two conditions could possibly contribute to the understanding of the causes of the high and wide-ranging prevalence rates and the pathophysiology of both diseases. Results: Of the 1068 participants 173 (16,2%) found to have RLS [RLS(+)] and 895 (83,8%) did not [RLS(-)]. Among the RLS(+) 173, all but 8 patients (4,6%) were underdiagnosed in terms of RLS. More than half of the patients with RLS had ‘severe’ or ‘very severe’ RLS. The onset of RLS was before or synchronous with the onset of MS in about a half of our patients. Conclusion: We conclude that RLS should be meticulously investigated in PwMS and MS can be a direct cause of RLS at least in part of PwMS. Our data about the timing of the onset of MS and RLS, along with the high prevalence of RLS in PwMS suggest that the pathologic changes in the initial phases of MS can possibly trigger RLS symptoms. © 2020 Elsevier B.V

Comparative analysis of fingolimod versus teriflunomide in relapsing–remitting multiple sclerosis

Background: Fingolimod and teriflunomide are commonly used in the treatment of relapsing-remitting multiple sclerosis (RRMS). These have not been compared in controlled trials, but only in observational studies, with inconclusive results. Comparison of their effect on relapse and disability in a real-world setting is therefore needed. Objectives: The objective of this study was to compare the efficacy of fingolimod and teriflunomide in reducing disease activity in RRMS. Methods: This multicenter, retrospective observational study was carried out with prospectively collected data from 15 centers. All consecutive RRMS patients treated with teriflunomide or fingolimod were included. Data for relapses, Expanded Disability Status Scale (EDSS) scores and brain magnetic resonance imaging (MRI) scans were collected. Patients were matched using propensity scores. Annualized relapse rates (ARR), disability accumulation, percentage of patients with active MRI and treatment discontinuation over a median 2.5-year follow-up period were compared. Results: Propensity score matching retained 349 out of 1388 patients in the fingolimod group and 349 out 678 in the teriflunomide group for final analyses. Mean ARR decreased markedly from baseline after 1 and 2 years of treatment in both the fingolimod (0.58–0.17 after 1 year and 0.11 after 2 years, p < 0.001) and teriflunomide (0.56–0.29 after 1 year and 0.31 after 2 years, p < 0.001) groups. Mean ARR was lower in fingolimod-treated patients than in those treated with teriflunomide at years 1 (p = 0.02) and 2 (p = 0.004). Compared to teriflunomide, the fingolimod group exhibited a higher percentage of relapse-free patients and a lower percentage of MRI-active patients after 2.5-year follow-up. Disability worsening was similar between the two groups. Patients were less likely to discontinue fingolimod than teriflunomide (p < 0.001). Conclusion: Fingolimod was associated with a better relapse control and lower discontinuation rate than teriflunomide. The two oral therapies exhibited similar effects on disability outcomes. © 2019 Elsevier B.V
