Filter by:Systemic autoimmune myopathies are a heterogeneous group of rheumatic diseases with progressive skeletal muscle weakness. The relevance of the peripherical neuromuscular electrical stimulation has never applied in the patients with systemic autoimmune myopathies. Therefore, the main objective of the present prospective, randomized, investigator-blind, placebo-controlled study is to evaluate the safety and efficacy of the application of an acute peripherical neuromuscular electrical stimulation session in patients with systemic autoimmune myopathies.
The risk for venous thromboembolism (VTE) in DM1 and in other inherited myopathies, which can lead to chronic immobilization, are unknown. The purpose of this study is to evaluate incidence of VTE in cohort of patients presenting with DM1 with a comparison to a group of other inheritable myopathies and to a community-based population.
This purpose of this study is to determine if tongue strength and tongue ultrasound measurements differentiates patients with untreated late-onset Pompe Disease (LOPD) from patients with acquires/hereditary myopathies or neuropathies. It is hypothesized that abnormalities in tongue function and structure in patients with LOPD may be useful in discriminating this condition from others that have similar presentations.
Critical illness in the ICU setting has high medical and socioeconomic importance. Critically ill patients frequently develop severe neurologic impairment during their course of disease, typically presenting as critical-illness-polyneuropathy (CIP), which is associated with an increased mortality rate. To date neither strategies are available to predict nor to specifically treat CIP. Diagnostic tests to determine CIP during the course of critical illness are available through nerve conduction studies. Further research is needed to find diagnostic tools to identify patients who are on high risk to develop CIP, which could encourage the evolution of new therapeutic strategies for CIP patients. The aims of the study are: 1. An early detection of changes in intramural neuronal networks of human colon samples induced by human blood serum from critically ill patients in order to predict the development of CIP 2. The comparison of different diagnostic tests to diagnose and monitor CIP during the course of critical illness (neurologic examination versus nerve conduction study versus neuromyosonography)
Systemic inflammation and sepsis cause multi organ failure including severe neurologic impairment in the course of disease. Neurologic failure typically presents as critical-illness-polyneuropathy/-myopathy and septic encephalopathy during sepsis and is associated with an increased mortality rate. Clinical parameters to determine the neurologic entities during the course of sepsis are heterogeneous. Further research for an association of clinical parameters and the patients' outcome is needed. The study aims toward differences in the clinical and neurological outcome of surgical and non-surgical septic patients in comparison to non-septic patients on ICU. The aim of the study is to identify clinical and diagnostic outcome predictors in septic patients.
This study is utilizing ultrasound measurement to measure neuromuscular disease status in adult patients. The hypothesis is the by quantifying ultrasound data, it is possible that ultrasound can be utilized as a tool to determine if a disease is responding to therapy or progressing.
We will examine whether the application of electro-neuro-muscular stimulation (ENMS) in critical care patients, can decrease the impact or severity of the critical illness myopathy (CIM) or neuropathy. We will also assess whether electro-neuro-muscular stimulation affect the incidence density rate of nosocomial pneumonia in the ICU. Patients will be divided into two groups, Group A and Group B chosen at random. In Group A conventional physiotherapy will be applied while in Group B, ENMS will also be applied additional to physiotherapy, in the quadriceps muscles. The total time of applying ENMS will be 1 hour, it will be applied before the start of the physiotherapy per day of hospitalization and for 10 days in each patient. The definition of CIM will be based on pathology muscular biopsy (quadriceps). Patients will undergo biopsy on the 1st and 11th day after entering the study. The technique of Gomori Trichrome will be used to determine the existence or absence of myopathy. In addition the ATPase technique will be applied at different prices of PH (PH: 9,4, PH: 4,6 and PH : 4.3), thus achieving a separation of myopathy and neuropathy. The primary outcome of the study will be the incidence of myopathy in both groups, at day 12th. Considering that the incidence of myopathy in critically ill patients is 80% reducing this rate by 50% in the intervention group using statistical power equal to 0.80 up to a level of p <0.05, 12 number of patients will be required in each group.
The objective of the proposed study is to evaluate the clinical utility of muscle ultrasonography for improving the diagnostic yield and safety of core muscle biopsy. Our facility currently uses core (needle) biopsy to obtain muscle samples in patients 18 years old or older. Currently, there is no imaging tool used to guide the actual biopsy. As muscle biopsy is an invasive and potentially painful procedure, improving the diagnostic yield of this test is important.
It is our primary hypothesis that statin drugs impair skeletal muscle mitochondrial function and that ubiquinol (the reduced active form of CoQ10) supplementation will block impairment of PCr recovery kinetics in patients using statins. The investigators propose a pilot study to extend our research to examine PCr recovery kinetics in 20 statin users randomized in a parallel arm study to either ubiquinol or placebo over 4 weeks.
Background: - Mitochondria are the parts of cells that help produce energy. Metabolism is the process by which the body uses energy to help cells grow and reproduce. Metabolic and mitochondrial disorders affect the body s ability to produce and store energy. These disorders can cause a wide variety of problems, but most often they affect the muscles and the brain, where energy requirements are high. Treatment is difficult because the exact source of the problem is hard to detect. - EPI-743 is a new drug that is based on vitamin E. Tests have shown that it can help improve the function of cells with mitochondrial problems. It may be able to treat people with genetic disorders that affect metabolism and mitochondria. Objectives: - To see if EPI-743 can improve energy production and use in people with mitochondrial or metabolic disorders. Eligibility: - Children between 2 and 11 years of age who have metabolic or mitochondrial problems. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. - The study will last about 13 months. Participants will have seven 3- to 5-day inpatient study visits about 3 months apart. - Participants will take either EPI-743 or a placebo for the first 6 months of the study. After 6 months, there will be a 1-month rest period. Then, those who received EPI-743 in the first 6 months will take the placebo for the next 6 months. Those who had the placebo will take EPI-743. - During each inpatient study visit, participants will have a physical exam. A 24-hour urine collection will be obtained. Blood samples will also be taken. Imaging studies and other tests may be performed as directed by the study researchers.
