The clinical features of 37 patients from 32 Israeli families with congenital myopathies evaluated between 1983 and 2004 are described: 13 children were diagnosed with congenital fiber type disproportion, 10 had myotubular myopathy, 7 had nemaline myopathy, 5 had central core disease, 1 had actin myopathy, and 1 had multi-minicore disease. There were 7 families (22%) that had parental consangui...
INTRODUCTION To the best of our knowledge, we describe for the first time the case of a woman who met the diagnostic criteria for fibromyalgia, did not respond to therapy for that disorder, and was subsequently diagnosed by biochemical and genetic studies with a mitochondrial myopathy. Treatment of the mitochondrial myopathy resulted in resolution of symptoms. This case demonstrates that mitoch...
Inactivation of cholinesterases at mammalian neuromuscular junctions (nmj) produces extensive muscle "necrosis." Fine-structurally, this myopathy begins near the nmj with an increase in large-diameter vesicles in the soleplasm, the dissolution of Z-disks, dilation of mitochondria, destruction of sarcoplasmic reticulum, and often a highly specific contracture of the muscle under the endplate. Si...
OBJECTIVE GNE myopathy is a rare recessive myopathy associated with inclusion bodies on muscle biopsy. The clinical phenotype is associated with distal muscle weakness with quadriceps sparing. Most of the current information on GNE myopathy has been obtained through studies of Jewish and Japanese patient cohorts carrying founder mutations in the GNE gene. However, little is known about GNE myop...
BACKGROUND Many patients taking statins often complain of muscle pain and weakness. The extent to which muscle pain reflects muscle injury is unknown. METHODS We obtained biopsy samples from the vastus lateralis muscle of 83 patients. Of the 44 patients with clinically diagnosed statin-associated myopathy, 29 were currently taking a statin, and 15 had discontinued statin therapy before the bi...
Apoptotic cell death of differentiated skeletal muscle has been reported in an experimental steroid-induced myopathy of rats. To investigate the underlying molecular changes in the apoptosis of skeletal muscle, in situ end labeling (ISEL), Fas expression, and Western blot analysis for apoptosis-related proteins in the soleus muscle of triamcinolone acetonide (TA)-induced myopathy of rats were s...
OBJECTIVE To characterise the main clinical phenotypes of debrancher deficiency myopathy and to increase awareness for this probably underdiagnosed disorder. METHODS The diagnosis of debrancher deficiency was established by laboratory tests, EMG, and muscle and liver biopsy. RESULTS Four patients with debrancher deficiency myopathy were identified in the Tyrol, a federal state of Austria wi...
OBJECTIVE In this study, we investigated the detailed clinical findings and underlying genetic defect in 3 presumably related Bulgarian families displaying dominantly transmitted adult onset distal myopathy with upper limb predominance. METHODS We performed neurologic, electrophysiologic, radiologic, and histopathologic analyses of 13 patients and 13 at-risk but asymptomatic individuals from ...
BACKGROUND Nemaline myopathy is a rare, non progressive congenital skeletal muscle disorder defined by the presence of inclusions known as nemaline rods in muscle fibers. Several clinical subtypes have been described, according to degree of muscle weakness, severity and age at onset. The course of nemaline myopathy is very slowly progressive, and death is usually due to respiratory failure. Car...
