Microstructure and mineral composition of dystrophic calcification associated with the idiopathic inflammatory myopathies
INTRODUCTION Calcified deposits (CDs) in skin and muscles are common in juvenile dermatomyositis (DM), and less frequent in adult DM. Limited information exists about the microstructure and composition of these deposits, and no information is available on their elemental composition and contents, mineral density (MD) and stiffness. We determined the microstructure, chemical composition, MD and ...
متن کامل[Non-invasive imaging of chronic inflammatory myopathies].
In patients with chronic inflammatory myositis noninvasive diagnostic modalities, such as magnetic resonance (MR) imaging, and ultrasonography (US), are able to demonstrate muscular edema, fluid collections, fatty infiltration, atrophy, fibrosis, and calcifications. Because MR imaging is sensitive to the presence of edema and offers better tissue differentiation, current MR imaging with fat sup...
متن کاملI-11 News in non dystrophic myotonias
potentials and twitch force were measured in muscle strips obtained from patients and controls. Of the 36 patients, 25 presented with chronic muscle weakness of varying degrees, up to wheelchair-dependence. The weakness was associated with intracellular Na overload and edema. Older patients revealed a vacuolar myopathy or a progressive muscular dystrophy. Weakness, intracellular Na overload and...
متن کاملThe non-dystrophic myotonias: molecular pathogenesis, diagnosis and treatment.
The non-dystrophic myotonias are an important group of skeletal muscle channelopathies electrophysiologically characterized by altered membrane excitability. Many distinct clinical phenotypes are now recognized and range in severity from severe neonatal myotonia with respiratory compromise through to milder late-onset myotonic muscle stiffness. Specific genetic mutations in the major skeletal m...
متن کاملRedefining the clinical phenotypes of non-dystrophic myotonic syndromes.
OBJECTIVE To redefine phenotypical characteristics for both chloride (ClCh) and sodium channelopathies (NaCh) in non-dystrophic myotonic syndromes (NDM). METHODS In a cross-sectional, nationwide study, standardised interviews and clinical bedside tests were performed in 62 genetically confirmed NDM patients, 32 ClCh and 30 NaCh. RESULTS Standardised interviews revealed that ClCh reported a ...
