Filter by:The purpose of this study is to learn about focal compressive median neuropathy at the wrist (Carpal Tunnel Syndrome) and outcomes of therapies (e.g. conservative and surgery) in the upper extremities of patients diagnosed with an inherited neuropathy. All patients enrolled in the Rare Diseases Clinical Research Network (RDCRN) Inherited Neuropathies Consortium (INC) Contact Registry who have marked one of the following disorders: CMT1A, CMT1B, CMT2A, CMT4, CMTX, other known CMT peripheral neuropathy, other unknown CMT peripheral neuropathy, or Hereditary Neuropathy with liability to Pressure Palsies (HNPP), will be invited via email to participate in this online study.
The purpose of this study is to determine whether the injection of triamcinolone and lidocaine is effective in relieving chronic abdominal wall pain.
Leukodystrophies, and other heritable disorders of the white matter of the brain, were previously resistant to genetic characterization, largely due to the extreme genetic heterogeneity of molecular causes. While recent work has demonstrated that whole genome sequencing (WGS), has the potential to dramatically increase diagnostic efficiency, significant questions remain around the impact on downstream clinical management approaches versus standard diagnostic approaches.
Brachial plexus nerve blocks provide superior analgesia over opioids while avoiding unwanted side effects. Single shot blocks with local anesthetic alone usually do not last the duration of the acute post-surgical pain period. This has led to the exploration of multiple adjuvants to increase the duration of single shot blocks, the most promising adjuvant being dexamethasone. Peri-neural administration is an off-label use of dexamethasone. While no adverse events have been reported in human clinical studies, logic would dictate that we minimize the dose needed to produce the desired effect. Most studies thus far have used peri-neural dexamethasone doses ranging from 4-10 mg. However, Albrecht et al. found no difference in block duration comparing 4 mg and 8 mg doses while Liu et al. reported equivalent block duration using doses of 1, 2 and 4 mg. Recent studies have evaluated whether systemic and peri-neural administrations of dexamethasone are equivalent, which would in turn imply a site of action. Results have been mixed. Four studies concluded peri-neural and intravenous administration are equivalent at prolonging analgesia, though one study had methodological errors, including the administration of intravenous dexamethasone to all patients. All of these studies used dexamethasone doses of 8 to 10 mg. One study where a lower dose (4 mg) was used found that peri-neural administration prolonged block duration whereas intravenous did not. With that, the rationale of our study is to determine if equivalent block-prolonging analgesia can be achieved using low dose (1 mg) dexamethasone given peri-neural or intravenous. Clinical experience at our centre has been that 1 mg dexamethasone added to 20 mL produces similar block duration to that reported in published studies using higher doses.
The disease Charcot-Marie-Tooth disease type 1A (CMT1A) is the most common inherited peripheral neuropathy, for which no treatment has proved its effectiveness. It is autosomal dominant, associated with a duplication of the chromosome 17p11.2 region which leads to overexpression of the gene and the protein-peripheral myelin protein-22 (PMP22), a major component of peripheral myelin. In animals and humans, PMP22 mRNA level of glutathione S-transferase theta 2 and Cathepsin A (markers of oxidative stress), detected in a skin biopsy are markers that may play a role in the prognosis evolution of the disease. Furthermore, several studies have shown that the administration of progesterone increased the expression of PMP22 gene (measured in a skin biopsy) and worsening symptoms. In contrast, anti-progestins reduce the synthesis of PMP22 and improve symptoms in rat CMT1A. The long-term safety of anti-progesterone was evaluated for mifepristone (RU486) ulipristal acetate and (EllaOne®). Few side effects have been reported including a few cases of endometrial hyperplasia reversible upon discontinuation of treatment. With the RU486, rare cases of adrenal androgen and failure have been observed. However, EllaOne® has low antagonistic action on the glucocorticoid receptor and no action on androgen receptors. The investigators therefore believe that it will be well tolerated in humans and will reduce the synthesis of PMP22 and the action of oxidative stress by improving disability of patients.
This is a 2-year follow-up study of a cohort of 60 CMT1A patients. The objective is to identify markers allowing to better understand the phenotypic variability observed on patients with CMT1A, to identify predictive markers of the disease's progression and to provide validated measurement tools that can be used as outcome measures in future clinical trials.
The purpose of this study is to determine whether PXT3003 is effective and safe in the treatment of Charcot-Marie-Tooth disease - Type 1 A (CMT1A). This double-blind study will assess in parallel groups 2 doses of PXT3003 compared to Placebo in CMT1A patients treated for 15 months.
Charcot Marie Tooth Disease is a family of inherited peripheral neuropathies, with over 70 causative genes identified to date.1-4 Muscle cramps are frequent in CMT, affecting up to 85% of patients with some subtypes of CMT. These cramps impact quality of life and have been identified as an important therapeutic target for clinical trials in CMT.1-4 There is no FDA approved treatment for muscle cramps.5 Mexiletine is a sodium channel blocker approved for treatment of arrhythmias. As a sodium channel blocker, mexiletine offers the promise of effective therapy for muscle cramps.
There is no golden universal standard for the diagnosis of Carpal Tunnel Syndrome (CTS). In this scenario, for a comparison of the effectiveness of the principal diagnostic tests CTS should determine how they affect the likelihood of disease through a clinical accuracy trial of good methodological quality in order to get answers to what is the best diagnostic strategy in clinical CTS practice. The paresthesia in nerve distribution territory median hands is the most common symptom in patients with CTS. The nuisance caused by paresthesia directly affects the quality of life of patients and impairs daily manual activities and sleep quality. To evaluate the remission of paresthesia is a major clinical criterion for improved STC being an expected relevant outcome for the patient. This study evaluated and compared the diagnostic accuracy of the ultrasonography (US) and electromyography (EMG), considering the postoperative status of remission of paresthesia as the reference standard in the diagnosis of CTS.
The goal of this study is to establish a genetic registry of patients with early-onset motor neuron and neuromuscular diseases. The investigators will collect samples from patients with a motor neuron or a neuromuscular disorder and their family members. The samples to be collected will be obtained using minimally invasive (whole blood) means. The research team will then extract high quality genomic DNA or RNA from these samples and use it to identify and confirm novel gene mutations and to identify genes which regulate the severity of motor neuron/neuromuscular diseases.
