25 Possible Causes for Aspiration Pneumonia, Compound Muscle Action Potential with Low Amplitude, Muscular Atrophy

  • Guillain-Barré Syndrome

    RESULTS: All six patients had different degrees of muscular atrophy at nadir and in two, respiratory muscles were involved.[] Thromboembolism, pneumonia, skin breakdown. Cardiac arrhythmia. Ileus. Aspiration pneumonia. Urinary retention. Psychiatric problems - eg, depression, anxiety.[] muscle action potentials reduced amplitude with relatively preserved conduction velocity implicates axonal neuropathy delayed/absent F waves implicates nerve root involvement[]

  • Dermatomyositis

    atrophy).[] Pulmonary manifestations range from aspiration pneumonia to interstitial lung disease (ILD), sometimes with complications such as pulmonary arterial hypertension (see these[] Low compound muscle action potentials (CMAP) amplitudes may not necessarily indicate a neuropathic process, as it may reflect muscle atrophy and fibrosis.[]

  • Myasthenia Gravis

    There is no muscular atrophy or loss of sensation.[] Complications Aspiration pneumonia due to throat muscle weakness. Acute respiratory failure during an exacerbation.[] 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,[]

  • Hereditary Motor and Sensory Neuropathy

    Charcot-Marie-Tooth disease Déjérine-Sottas disease Hereditary motor and sensory neuropathy, types I-IV Hypertrophic neuropathy of infancy Peroneal muscular atrophy (axonal[] Laryngeal dysfunction with aspiration pneumonia.[] Compound muscle action potentials are either absent or low amplitude with motor conduction velocities ranging from 3 to 10 meters per second.[]

  • Distal Hereditary Motor Neuropathy Type 1

    HMN has also been referred to as distal spinal muscular atrophy (DSMA).[] Laryngeal dysfunction with aspiration pneumonia.[] Compound muscle action potentials are either absent or low amplitude with motor conduction velocities ranging from 3 to 10 meters per second.[]

  • Charcot-Marie-Tooth Disease Type 2S

    atrophy with respiratory distress (sequence analysis of IGHMBP2 gene) Charcot-Marie-Tooth disease (disease exome based NGS panel for 43 genes) Spinal muscular atrophy (NGS[] Laryngeal dysfunction with aspiration pneumonia.[] Electrodiagnostic studies showed normal or moderately slowed motor nerve conduction velocities (MNCVs) but very low motor compound muscle action potential (CMAP) amplitudes[]

  • Neuromuscular Junction Disorder

    Spinal muscular atrophies: Amyotrophic lateral sclerosis (ALS), or motor neuron disease Infantile progressive spinal muscular atrophy Intermediate spinal muscular atrophy[] Aspiration pneumonia is clearly an undesirable outcome in someone with already compromised respiratory function.[] 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.[]

  • Monomelic Amyotrophy

    Since its original description by Keizo Hirayama in 1959, "juvenile muscular atrophy of the unilateral upper extremity" has been described under many nomenclatures from the[] In later stages of the disorder, aspiration pneumonia can develop, and maintaining a healthy weight can become a significant problem that may require the insertion of a feeding[] The nerve conduction studies frequently demonstrate low-amplitude compound muscle action potentials (CMAPs) commensurate with degree of weakness and atrophy.3,8 The electromyographic[]

  • Inclusion Body Myositis

    Sporadic inclusion body myositis (sIBM) is a slowly progressive, red-rimmed vacuolar myopathy leading to muscular atrophy and progressive weakness; it predominantly affects[] The incidence of dysphagia, rate of aspirations, rate of aspiration pneumonias and treatment results of dysphagia were analyzed.[] However, the low compound muscle action potential amplitudes could be explained by the loss of excitable muscle tissue that occurs in myopathies.[]

  • Neuropathy

    Types I and II (varieties of Charcot-Marie-Tooth disease, also called peroneal muscular atrophy) are the most common; they are usually autosomal dominant disorders but can[] 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[] Patients have relatively normal nerve conduction velocities but low amplitude sensory nerve action potentials and compound muscle action potentials.[]
