Neurophysiological evaluation of visual function in iRBD: potential role in stratifying RBD conversion risk.
2021
Abstract Study objectives To evaluate neurophysiological alterations of visual function in idiopathic REM sleep Behavior Disorder (iRBD) both as markers and predictors of neurodegenerative disorders. Methods In a longitudinal follow-up study of 46 consecutive iRBD patients (follow-up duration 8.4 ± 3.4 years), the baseline parameters in luminance-contrast pattern (VEPp), red-green color (VEPc) and motion-onset (VEPm) Visual Evoked Potentials in iRBD were compared to early (ePD) and advanced (aPD) Parkinson's Disease subjects. Parameters of latency and amplitude of iRBD converters to neurodegenerative disease were compared with those of the non-converters. Results The VEP P100 mean latency v…
Transcranial direct current stimulation for treatment of freezing of gait: A cross-over study
2014
Background and objective Progression of Parkinson's disease (PD) is frequently characterized by the occurrence of freezing of gait (FOG) representing a disabling motor complication. We aim to investigate safety and efficacy of transcranial direct current stimulation of the primary motor cortex of PD patients with FOG. Methods In this cross-over, double-blind, sham-controlled study, 10 PD patients with FOG persisting in “on” state underwent anodal and sham direct current stimulation for 5 consecutive days. Clinical assessment over a 1-month period was performed. Results A significant improvement of gait, as assessed by the Stand Walk Sit test, with reduction in number and duration of FOG epi…
Beneficial Effect of Foot Plantar Stimulation in Gait Parameters in Individuals with Parkinson’s Disease
2020
New treatments based on peripheral stimulation of the sensory-motor system have shown to be promising in rehabilitation strategies for patients with neurological disorders, including Parkinson's disease (PD), especially in regards to reducing gait impairment, and hence, the incidence of falls. The aim of this study was to evaluate the change in several gait parameters measured by sensor inertial measurement in PD patients after acute plantar stimulation, under the distal phalanx of the big toe, and underneath the head of the first metatarsal joint of both feet, using a 3D printing insole. In order to assess whether the effects are selective for PD patients, we compared the effect of the tre…
Associated Factors and Liver Disease Severity for Decreased Bone Mineral Density in HIV Mono- and HIV/HCV Co-infected Patients
2015
Objective: We assessed the prevalence and risk factors of decreased bone mineral density (BMD) in patients mono-infected with human immunodeficiency virus (HIV) or co-infected with hepatitis C virus (HIV/HCV). We also evaluated whether bone loss was linked to lipid asset in both groups and to severity of liver fibrosis in the co-infected group. Methods: We consecutively enrolled 194 HIV-patients (129 mono-infected and 65 co-infected). All HIV-patients underwent dual-energy X-ray absorptiometry (DXA), while co-infected patients underwent transient elastography. Advanced liver fibrosis was defined as a median liver stiffness ≥ 9.5 kPa. Fibrosis was also assessed in all the HIV-patients using …
D-penicillamine in Wilson's disease presenting as acute liver failure with hemolysis.
1982
Wilson's disease in a young woman presenting with an acute course is described. The clinical manifestations were fulminant hepatic failure associated with marked intravascular hemolysis. Immediate D-penicillamine and high-dose steroid therapy did not influence the course of the disease. Necropsy revealed an increased hepatic copper content and cirrhosis with extensive necrosis of the liver.
Inflammatory mediators as biomarkers in brain disorders.
2013
Neurodegenerative diseases such as Alzheimer, Parkinson, amyotrophic lateral sclerosis, and Huntington are incurable and debilitating conditions that result in progressive death of the neurons. The definite diagnosis of a neurodegenerative disorder is disadvantaged by the difficulty in obtaining biopsies and thereby to validate the clinical diagnosis with pathological results. Biomarkers are valuable indicators for detecting different phases of a disease such as prevention, early onset, treatment, progression, and monitoring the effect of pharmacological responses to a therapeutic intervention. Inflammation occurs in neurodegenerative diseases, and identification and validation of molecules…
Gadolinium accumulation after contrast-enhanced magnetic resonance imaging: Which implications in patients with Crohn's disease?
2017
Crohn's disease (CD) is a chronic inflammatory condition of the bowel, characterized by an alternation of remission and relapse phases, leading to a progressive intestinal damage with loss of function. Magnetic resonance enterography has been widely used in the past for the evaluation of fistulizing disease, but its use increased over time, being considered helpful in different moments of disease course. Intravenous injection of Gadolinium-based contrast agents has been demonstrated to be crucial to assess mucosal inflammation, transmural involvement, and extraintestinal disease. Recently, Gadolinium accumulation in human tissues has been increasingly reported, although clinical implication…
PROTON MAGNETIC RESONANCE SPECTROSCOPY IN DEMENTIA OF ALZHEIMER TYPE
1997
Reduced N-acetyl aspartate (NAA) and increased myo-inositol (MI) levels have been reported in patients with dementia of Alzheimer type (DAT) in comparison with controls. We wished to assess the validity of these findings and to evaluate possible correlations of metabolite proportions with cognitive dysfunction in DAT. Twelve patients with DAT and 10 healthy age-matched controls were included. The severity of dementia was assessed using different scales including the Mini-Mental State Examination. MRS was performed with a conventional 1.5 Tesla scanner in a single voxel in the centrum semi-ovale (TE = 30 ms or TE = 136 ms; TR = 1500 ms). The evaluation of MRS results was limited by low inter…
Biomarker sources for Parkinson's disease: Time to shed tears?
2015
Abstract Parkinson's disease (PD) is the most frequent neurodegenerative movement disorder. In nearby future its importance will increase, especially due to changes in age structure. There are still substantial problems in terms of early diagnosis of the disease. In clinical practice, the diagnosis of PD is still based on the evaluation of clinical presentation and is supported by various ancillary tests with heterogeneous predictive value. In regard to diagnosis and disease monitoring, body fluid-based biomarkers have become an indispensable tool in today's medicine. In this Current Opinion we briefly address the present approaches to biomarker development for PD, including clinical trials…
Heart failure and anti tumor necrosis factor-alpha in systemic chronic inflammatory diseases.
2013
Tumor necrosis factor alpha (TNF-alpha) antagonists have emerged as an effective therapy for patients with diseases as Crohn's disease, rheumatoid arthritis, and other chronic systemic inflammatory diseases. In the last years, there has been a growing interest in the role that inflammatory cytokines, which sustain the pathogenesis of these diseases, plays in regulating cardiac structure and function, particularly in the progression of chronic heart failure. In fact there is an increase of anti-TNF alpha levels in advanced heart failure but the treatment with anti-TNF alpha has been shown to worsen the prognosis of heart failure in randomized controlled trials. Patients with rheumatoid arthr…
