18 Possible Causes for Aspiration Pneumonia, Compound Muscle Action Potential with Low Amplitude, Myositis

  • Dermatomyositis

    Myositis is a rare condition that affects the muscles. The term myositis means "inflammation of the muscles".[nhs.uk] Pulmonary manifestations range from aspiration pneumonia to interstitial lung disease (ILD), sometimes with complications such as pulmonary arterial hypertension (see these[orpha.net] Low compound muscle action potentials (CMAP) amplitudes may not necessarily indicate a neuropathic process, as it may reflect muscle atrophy and fibrosis.[doi.org]

  • Inclusion Body Myositis

    […] before a clinical diagnosis of inclusion body myositis was made.[ncbi.nlm.nih.gov] The incidence of dysphagia, rate of aspirations, rate of aspiration pneumonias and treatment results of dysphagia were analyzed.[ncbi.nlm.nih.gov] However, the low compound muscle action potential amplitudes could be explained by the loss of excitable muscle tissue that occurs in myopathies.[jamanetwork.com]

  • Myasthenia Gravis

    […] adopt different treatment strategies compared to those applied in myasthenia or myositis alone.[ncbi.nlm.nih.gov] Complications Aspiration pneumonia due to throat muscle weakness. Acute respiratory failure during an exacerbation.[patient.info] Distinguishing features of the RNS test in LEMS and MG are confirmed in this direct comparison study: the low compound muscle action potential amplitude, decrement at LRS,[ncbi.nlm.nih.gov]

  • Guillain-Barré Syndrome

    Yes Acute myositis or other rhabdomyolysis No No Yes Abrupt onset and consistent neuroimaging?[kundoc.com] Thromboembolism, pneumonia, skin breakdown. Cardiac arrhythmia. Ileus. Aspiration pneumonia. Urinary retention. Psychiatric problems - eg, depression, anxiety.[patient.info] muscle action potentials reduced amplitude with relatively preserved conduction velocity implicates axonal neuropathy delayed/absent F waves implicates nerve root involvement[step2.medbullets.com]

  • Neuromuscular Junction Disorder

    High dose steroids are therefore used, usually in conjunction with other immunosuppressive agents. 1.3 Overlap Myositis: This is a condition in which an inflammatory myositis[academic.sun.ac.za] Aspiration pneumonia is clearly an undesirable outcome in someone with already compromised respiratory function.[jnnp.bmj.com] EMNG showed signs of myopathy and low compound muscle action potential (CMAP) amplitude (0,15 mV) on lower extremities. Muscle and nerve biopsy were normal.[neurology.org]

  • Acquired Amyloid Myopathy

    MAC expression indicates a role for complement activation in pSS associated myositis.[diva-portal.org] Complications such as aspiration pneumonia become rather eminent. Several of these patients should be counseled regarding the insertion of a gastric feeding tube.[nature.com] Low compound muscle action potentials (CMAP) amplitudes may not necessarily indicate a neuropathic process, as it may reflect muscle atrophy and fibrosis.[journal.frontiersin.org]

  • Neuropathy

    Compounding the problem of aspiration pneumonias and chronic lung disease is the presence of relative insensitivity to hypoxemia [ 23 - 26 ], which limits ability to cope[ncbi.nlm.nih.gov] Patients have relatively normal nerve conduction velocities but low amplitude sensory nerve action potentials and compound muscle action potentials.[merckmanuals.com] […] refractory CD or CD-associated ataxia, may have a role in the management of CD-associated PN Keywords Celiac Disease Peripheral Neuropathy Coeliac Disease Inclusion Body Myositis[doi.org]

  • Lambert Eaton Myasthenic Syndrome

    Differential diagnosis In 60% of LEMS patients, a different diagnosis was initially made such as myasthenia gravis (MG), inclusion body myositis, Guillain-Barré syndrome ([orpha.net] Approximately 2 months after the operation, he had aspiration pneumonia with respiratory failure.[jmedicalcasereports.biomedcentral.com] Distinguishing features of the RNS test in LEMS and MG are confirmed in this direct comparison study: the low compound muscle action potential amplitude, decrement at LRS,[ncbi.nlm.nih.gov]

  • Acute Juvenile Hemorrhagic Cystitis

    Myositis Specific Antibodies Myositis specific antibodies have a controversial pathogenic role.[frontiersin.org] - aspiration with granulomatous bronchiolitis and lipoid pneumonia Case 278: 62 year old man with anterior mediastinal mass - atypical carcinoid tumor of thymus Case 266:[pathologyoutlines.com] Garrity et al. [74] reported the treatment of 7 patients with chronic and refractory orbital myositis.[eyewiki.aao.org]
