The clinical and laboratory findings of a patient with juvenile acid maltase deficiency are presented. The patient died from respiratory muscle weakness at age 31 years. Muscle biopsy shortly prior to his death showed remarkable vacuolation affecting exclusively type I fibres and mild myopathic changes of both types of muscle fibres, while the muscle biopsy at age 26 years had shown no evidence...
In chronic heart failure (HF) from systolic cardiac dysfunction, the degree of exercise intolerance is not directly related to the degree of cardiac weakness.1–5 Somewhat surprisingly symptoms that typify HF, including shortness of breath and fatigue, are often directly related to the abnormalities of the skeletal musculature in HF. Our understanding of the features of skeletal myopathy is evol...
OBJECTIVE To show cancer association is a risk factor other than statin exposure for anti-3-hydroxy-3-methylglutaryl coenzyme A reductase autoantibody-positive (anti-HMGCR Ab+) myopathy. METHODS We analyzed the clinical features and courses of 33 patients (23 female and 10 male) with anti-HMGCR Ab+ myopathy among 621 consecutive patients with idiopathic inflammatory myopathies. RESULTS Amon...
BACKGROUND GNE myopathy is a rare genetic disease characterized by progressive muscle atrophy and weakness. It is caused by biallelic mutations in the GNE gene that encodes for the bifunctional enzyme, uridine diphosphate (UDP)-N-acetylglucosamine (GlcNAc) 2-epimerase/N-acetylmannosamine (ManNAc) kinase. Typical characteristics of GNE myopathy include progressive myopathy, first involving anter...
dacarbazine (dtic) is a synthetic chemical antitumor agent which is used to treat malignant melanoma and hodgkin’s disease. dtic is a prodrug which is converted to an active form undergoing demethylation by liver enzymes. the active form prevents the progress of disease via alkylation of dna strand. in the structure of this drug, the imidazole ring, a triazen chain and carboxamide group exist. ...
X-linked myotubular myopathy (XLMTM) is a congenital neuromuscular disorder characterized by profound hypotonia and severe skeletal muscle weakness in the affected newborn males. The pathology is associated with mutations in the MTM1 gene leading to loss of function of the resulting encoded protein, myotubularin. Myotubularin is a phosphoinositol lipid phosphases known to be involved in endosom...
BACKGROUND Late-onset Pompe disease (LOPD) is a rare treatable lysosomal storage disorder characterized by progressive lysosomal glycogen accumulation and muscle weakness, with often a limb-girdle pattern. Despite published guidelines, testing for LOPD is often overlooked or delayed in adults, owing to its low frequency compared to other muscle disorders with similar muscle patterns. Next-gener...
Neutral lipid storage disease with myopathy (NLSDM) is a rare autosomal recessive disorder of neutral lipid metabolism. Clinical manifestations include progressive skeletal myopathy, cardiomyopathy, and liver dysfunction. Clinical severity is variable and additional symptoms may include diabetes mellitus, chronic pancreatitis, hypothyroidism, neurosensory hearing loss, and short stature. We rep...
Bethlem myopathy is an early-onset benign autosomal dominant myopathy with contractures caused by mutations in collagen type VI genes. It has been reported that onset occurs in early childhood. We investigated the natural course of Bethlem myopathy in five previously published kindreds and two novel pedigrees, with particular attention to the mode of onset in 23 children and the progression of ...
