BACKGROUND Charcot-Marie-Tooth type 1A disease (CMT1A) is a rare orphan inherited neuropathy caused by an autosomal dominant duplication of a gene encoding for the structural myelin protein PMP22, which induces abnormal Schwann cell differentiation and dysmyelination, eventually leading to axonal suffering then loss and muscle wasting. We favour the idea(More)
UNLABELLED We report the case of a pregnant woman presenting with Guillain-Barré syndrome in which her neurologic status worsened immediately after delivery under epidural analgesia. We believe that the anesthetic technique may have played a role in the disease progression. Because of this potential association, the risks of worsening neurologic status(More)
Duchenne Muscular Dystrophy (DMD) is a complex process involving multiple pathways downstream of the primary genetic insult leading to fatal muscle degeneration. Aging muscle is a multifactorial neuromuscular process characterized by impaired muscle regeneration leading to progressive atrophy. We hypothesized that these chronic atrophying situations may(More)
BACKGROUND DNA microarray technology has had a great impact on muscle research and microarray gene expression data has been widely used to identify gene signatures characteristic of the studied conditions. With the rapid accumulation of muscle microarray data, it is of great interest to understand how to compare and combine data across multiple studies.(More)
INTRODUCTION Neurophysiological study of respiratory structures usually relies upon diaphragm electromyography and phrenic nerve conduction study, which do not assess the afferent sensory pathways. OBJECTIVE To assess the feasibility of respiratory evoked potentials (REPs) and sympathetic skin responses (SSRs) elicited by inspiratory occlusion. METHODS(More)
BACKGROUND Myotonic Dystrophy type 1 (DM1) is one of the most heterogeneous hereditary disease in terms of age of onset, clinical manifestations, and severity, challenging both medical management and clinical trials. The CTG expansion size is the main factor determining the age of onset although no factor can finely predict phenotype and prognosis.(More)
Unfortunately, the original version of this article [1] contained an error due to a typographical error in the computer code used. This meant the percentage improvement over baseline of the endpoints CMTNS, ONLS, 9HPT and DML was slightly increased. Therefore some of the values in Tables 3, 4, Additional file 4: Table S4 and Fig. 4 are incorrect. However(More)
Seipinopathies are a group of inherited diseases affecting upper and lower motor neurons due to mutations in the Berardinelli-Seip congenital lipodystrophy 2 gene (BSCL2). We report a French family carrying the N88S mutation in the BSCL2 gene. A 12-yr-old girl complained of bilateral asymmetrical pes cavus with right hand motor deficit and amyotrophy,(More)
Brody disease was first described as a benign pseudo-myotonic disorder with muscular stiffness, which increased with exercise. Biochemical and genetic studies have pointed out its close relationship to a functional defect of the fast-twitch sarcoplasmic reticulum Ca(++) ATPase pump (SERCA1) encoded by the ATP2A1 gene located on chromosome 16.
