Diagnosis: Myopathy

چکیده
by Edward C. Smith, MD, and Dwight D. Koeberl, MD, PhD The rheumatologist is frequently called upon to evaluate patients with complaints of myalgia, muscle cramping, and fatigue. Because these symptoms may be nonspecific and lack any clear temporal or anatomic pattern, their workup may entail costly and uninformative tests. When similar symptoms emerge during or following physical exertion, a metabolic myopathy should be suspected. Recurrent myoglobinuria, exercise intolerance, and mild fixed proximal muscle weakness are also frequently encountered in metabolic myopathies. Although inflammatory myopathies may present in a similar fashion, such a pattern should prompt a thorough evaluation for an underlying metabolic myopathy. This review will discuss an approach to the diagnosis and treatment of several of the more common metabolic myopathies.

ABSTRACT To determine the usefulness of a method of percutaneous needle muscle biopsy in patients with suspected idiopathic inflammatory Myopathy. The yield of percutaneous needle muscle biopsy was studied in 15 patients during 1997-2000 who were hospitalized in Hazrat Rasool Akram hospital.

متن کاملHistochemical And Electron Microscopic Diagnosis Of Mitochondrial Myopathy: The First Case Report From Iran
Muscle tissue, skeletal muscle as well as cardiac muscle, is commonly affected in mitochondrial disorders. One explanation for this observation is that muscle tissue has a high-energy demand and therefore is more sensitive to a deficiency of mitochondrial energy production than some other tissues. In mitochondrial disorders, skeletal muscle tissue may be affected primarily by defective respi...

Introduction: Myopathy and rhabdomyolysis are not common in children and, if not detected and do not treated it will be associated with high mortality and morbidity rate. The causes of rhabdomyolysis include hypokalemia, trauma, viral myositis, poisoning, rheumatoid diseases, and metabolic myopathies. Rhabdomyolysis treatment includes rapid supportive care and treatment of the underlying dise...

متن کاملCongenital fiber type disproportion: a rare type of congenital myopathy: a report of four cases.
Congenital fiber type disproportion is a rare type of congenital myopathy which presents as hypotonia, delayed motor milestones and dysmorphic facies. During the past 2 years we received 449 muscle biopsies, of which 4 cases were diagnosed as congenital fiber type disproportion (CFTD). In addition to CFTD, one case also had centronuclear features. Three of them were females and one was a male c...
