828 Possible Causes for EMG Shows Evidence of Reinnervation, Muscle Biopsy Abnormal, Muscle Biopsy showing Variation In Fiber Size

  • Muscular Dystrophy

    This condition is typically characterized by large and abnormally distributed mitochondria on muscle biopsy, which can distinguish this condition from the other muscle conditions[ncbi.nlm.nih.gov] Muscle biopsies of the proband showed large variations in muscle fiber size, necrotic and regenerating fibers and an increase in endomysial collagen tissue.[ncbi.nlm.nih.gov] Under the microscope, the muscle of a positive biopsy generally shows dead tissue and abnormally large muscle fibers.[cedars-sinai.edu]

  • Duchenne Muscular Dystrophy

    Diagnosis of Duchenne Muscular Dystrophy A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle[disabled-world.com] […] fibers) For Duchenne and Becker muscular dystrophies, muscle biopsy may show whether dystrophin, a muscle protein, is missing or abnormal, and DNA testing is used to analyze[webmd.com] A muscle biopsy (taking a sample of muscle) for dystrophin studies can be done to look for abnormal levels of dystrophin in the muscle.[genome.gov]

  • Becker Muscular Dystrophy

    Electromyography was abnormal in all patients. Muscle biopsy in 1 patient demonstrated normal immunostaining for dystrophin.[ncbi.nlm.nih.gov] The muscle biopsy was myopathic with increased fiber size variation and many internal nuclei, but no dystrophy. No comorbidity was found.[ncbi.nlm.nih.gov] Elevated serum CK Skeletal muscle biopsy showing decreased dystrophin quantity Panel overlap The gene on this panel is also included on our Autism Intellectual Disability[unmc.edu]

  • Motor Neuron Disease

    For patients with MND affecting the LMNs, the EMG will show evidence of: (1) acute denervation, which is ongoing as motor neurons degenerate, and (2) chronic denervation and[en.wikipedia.org] The results of electromyography and muscle biopsy were compatible with ALS. However, supranuclear vertical gaze palsy and slow saccades are seen.[ncbi.nlm.nih.gov] reinnervation of the muscle, as the remaining motor neurons attempt to fill in for lost motor neurons.[en.wikipedia.org]
