11 Possible Causes for Creatine Phosphokinase Increased, Electromyogram Abnormal, Percussion Myotonia

  • Myotonia Congenita

    The diagnosis were based upon family history, clinical findings of percussion myotonia, had grip myotania, prominent muscular hypertrophy and confirmed by electromyographic[ncbi.nlm.nih.gov] The electromyogram tests the electrical impulses from the affected muscles. The abnormal repetitive impulses can confirm this disease.[symptoma.com] Distribution/anatomy Time course Onset/age Myotonia is usually mild, approximately 50% may have percussion myotonia.[rrnursingschool.biz]

  • Muscular Dystrophy

    Myotonia (prolonged muscle contraction) occurs spontaneously or is elicited by voluntary activity or by mild stimulation, such as tapping on a muscle (percussion myotonia)[neuropathology-web.org] The diagnosis of muscular dystrophy is based on the results of muscle biopsy, increased creatine phosphokinase (CpK3), electromyography, and genetic testing.[en.wikipedia.org] […] typically elicited by percussion of the thenar eminence with a tendon hammer—‘percussion myotonia’.[doi.org]

  • Secondary Myopathy

    Muscle hypertrophy may be seen Grip and percussion myotonia can be seen Tx : Mexiletene.[sites.google.com] Although changes seen on electromyography are not pathognomonic for any specific disease process, an abnormal electromyogram can indicate if a neuropathy or neuromuscular[aafp.org] Cirioni O, Weimer LE, Fragola V, et al.(2013) Sustained Increase of Serum Creatine Phosphokinase Levels and Progressive Muscle Abnormalities Associated with Raltegravir use[hiv.imedpub.com]

  • Myopathy

    Myotonia can be elicited by percussion, occurs by impaired relaxation of muscle due to repetitive depolarization of the muscle.[doi.org] The laboratory evaluation was remarkable for the marked increase in the serum lactate dehydrogenase and creatine phosphokinase levels.[ncbi.nlm.nih.gov] Electroencephalographic abnormalities have been noted in several patients with the early-onset form of the disease before clinically apparent seizure activity begins.[anesthesiology.pubs.asahq.org]

  • Limb-Girdle Muscular Dystrophy

    Patients with myotonic dystrophy type 1 may present subtle myotonia and it may be necessary to search for tenar muscle percussion myotonia 15.[doi.org] We present a 19-year-old girl with epilepsy and elevated creatine phosphokinase (CPK) concentration.[ncbi.nlm.nih.gov] Due to increased CPK, myopathy was suspected and muscle biopsy was performed.[ncbi.nlm.nih.gov]

  • Myoadenylate Deaminase Deficiency

    "Action" or grip myotonia may be seen. However, percussion myotonia is rare. There may be an associated neuropathy.[neuroweb.us] phosphokinase, hypoketotic hypoglycemia, and increased lipid in muscle.[rheumaknowledgy.com] The electromyogram showed myopathic abnormalities in the biceps, it was normal in quadriceps and anterior tibial muscles. A quadriceps muscle biopsy was performed.[ncbi.nlm.nih.gov]

  • Schwartz-Jampel Syndrome

    Further investigation showed some typical facial features of the syndrome, percussion myotonia and abnormal EMG pattern characterized by continuous muscle activity at rest[ncbi.nlm.nih.gov] These clinical findings, along with abnormal electromyogram and muscle biopsy, are consistent with Schwartz-Jampel syndrome.[ncbi.nlm.nih.gov] High serum creatine kinase Increased CPK Increased creatine kinase Increased creatine phosphokinase Increased serum CK Increased serum creatine kinase Increased serum creatine[rarediseases.info.nih.gov]

  • Proximal Myopathy with Extrapyramidal Signs

    "Action" or grip myotonia may be seen. However, percussion myotonia is rare. There may be an associated neuropathy.[neuroweb.us] The electromyogram is abnormal, with myopathic features.[intranet.tdmu.edu.ua] High serum creatine kinase Increased CPK Increased creatine kinase Increased creatine phosphokinase Increased serum CK Increased serum creatine kinase Increased serum creatine[rarediseases.info.nih.gov]

  • Distal Myopathy Type 3

    "Action" or grip myotonia may be seen. However, percussion myotonia is rare. There may be an associated neuropathy.[neuroweb.us] Neuropathy Atrophy Stiffness Myoglobinuria Other features History Physical Examination Laboratory Findings Creatine Kinase Muscle Biopsy Electromyogram Endocrine Cushing's[wikidoc.org] High serum creatine kinase Increased CPK Increased creatine kinase Increased creatine phosphokinase Increased serum CK Increased serum creatine kinase Increased serum creatine[rarediseases.info.nih.gov]

  • Spondylo-Ocular Syndrome

    myotonia Frontal balding Preauricular pit Accelerated skeletal maturation Facial hypotonia Testicular atrophy Decreased body weight Low posterior hairline Webbed neck Atrial[mendelian.co] […] external sphincter electromyogram reflecting loss of anterior horn cells in Onuf's nucleus in the sacral cord is highly suggestive of multiple system atrophy in the appropriate[annalsofian.org] CSF protein Positive Romberg sign Mildly elevated creatine phosphokinase Generalized amyotrophy Sensory axonal neuropathy Increased variability in muscle fiber diameter Ophthalmoparesis[mendelian.co]
