We have studied the presence of calcitonin gene-related peptide (CGRP) immunoreactivity at the human motor end-plate in intercostal muscles from 6 normal subjects. Only a small proportion of end-plates were positively stained in the muscle. Different metabolic states at single motor end-plates or variable rates of CGRP synthesis in separate motoneurones(More)
Irreversible connective tissue proliferation in muscle is a pathological hallmark of Duchenne muscular dystrophy (DMD), a genetic degenerative muscle disease due to lack of the sarcolemmal protein dystrophin. Focal release of transforming growth factor-beta1 (TGF-beta1) is involved in fibrosis development. Murine muscular dystrophy (mdx) is genetically(More)
Emery-Dreifuss muscular dystrophy (EDMD) is an X-linked inherited disease characterized by early contracture of the elbows, Achilles tendons and post-cervical muscles, slow progressive muscle wasting and weakness and cardiomyopathy presenting with arrhythmia and atrial paralysis: heart block can eventually lead to sudden death. The EDMD geneencodes a novel(More)
Azathioprine (Aza) has been used alone or in combination with steroids for two groups of myasthenic patients. Positive responses were noted in 75% of patients on Aza alone and in 70% receiving the combined regimen. The clinical course of the two groups differed in terms of respiratory crisis and need for plasma exchange. With an appropriate Aza(More)
Very few studies on bone mineral density and bone metabolism in Duchenne muscular dystrophy (DMD) have been reported. DMD is a severe, progressive muscular disease resulting in death at a young age. No specific therapies are available, but corticosteroids induce improvement and slower progression of the disease. However, long-term steroid therapy is a(More)
We have raised an anti-emerin polyclonal antibody against a fusion protein encompassing most of the hydrophilic portion of emerin. Using this antibody, we have analyzed emerin expression in Emery-Dreifuss muscular dystrophy (EDMD) patients and controls, by immunocytochemistry, in skeletal muscle and skin, and by immunoblot, in peripheral blood mononuclear(More)
Idiopathic inflammatory myopathies (IIM) are muscle diseases of autoimmune pathogenesis characterized by mononuclear cell infiltration within muscle tissue. Since immune cell homing and accumulation at the site of antigenic challenge is usually mediated by chemokines, we evaluated the expression of 2 beta-chemokines--monocyte chemoattractant protein-1(More)
Aim of this study is to verify whether there is concordance between disease's severity, health-related quality of life (HRQoL) and disability in patients with myasthenia gravis (MG). 102 MG patients were clustered on the basis of HRQoL and disability scores into three groups: low disability and low HRQoL decrement (51 patients), intermediate disability and(More)
Patients with multiple sclerosis (MS) frequently report symptoms related to vestibular disorders in the course of their disease. At present, the fundamental tests assessing vestibulospinal involvement are posturography and vestibular evoked myogenic potentials (VEMPs). While posturography cannot be performed in every subject requiring minimal stance(More)
The aims of this study were to assess the efficacy of video-assisted thoracoscopic extended thymectomy (VATET) as a treatment for myasthenia gravis (MG) and to identify prognostic factors for thymectomy success. Clinical efficacy and variables influencing outcome were assessed by life-table and Cox proportional hazards regression analysis. Complete stable(More)
