12 Possible Causes for Aspiration Pneumonia, Bell's Palsy, Compound Muscle Action Potential with Low Amplitude

  • Guillain-Barré Syndrome

    The differential diagnosis was between a variant of GBS and Bell's palsy.[] 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[]

  • Myasthenia Gravis

    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,[] Patients with pneumonia should be admitted because they often are taking immunosuppressant medications and are at a high risk for aspiration pneumonia. [17] Plasmapheresis[]

  • Miller-Fisher Syndrome

    Bell's palsy. Nonrecurrent v recurrent and unilateral v bilateral . Arch. Otolaryngol. 110 , 374–377 (1984).[] The immediate cause of death was considered to be aspiration pneumonia.[] CBs resolved, distal compound muscle action potential (CMAP) amplitudes increased and SNAPs normalized on subsequent testing.[]

  • Neuropathy

    palsy) foot or shin pain, weakness or altered sensation The most common type of mononeuropathy is carpal tunnel syndrome (CTS) .[] 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.[]

  • Rabies

    As the neurologic phase of rabies advances, chest radiographs might reveal infiltrates due to aspiration, acute respiratory distress syndrome, nosocomial pneumonia, or congestive[] Motor nerve conduction studies showed decreased conduction with dispersion of compound muscle action potential, low amplitude with prolonged distal latency and decreased nerve[]

  • Neuromuscular Junction Disorder

    Bell’s Palsy Bell’s palsy is the most common cause of unilateral facial paralysis.[] 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.[]

  • Hereditary Motor and Sensory Neuropathy

    It may be misdiagnosed as Charcot-Marie Tooth disease or Bell’s palsy. HNPP is a progressive hereditary disorder, but the symptoms can be so mild that they go unnoticed.[] 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.[]

  • Lambert Eaton Myasthenic Syndrome

    Approximately 2 months after the operation, he had aspiration pneumonia with respiratory failure.[] 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,[] amplitude compound muscle action potential (CMAP), a decremental response to low rate stimulation, and an incremental response to high rate stimulation or after brief exercise[]

  • Infantile Hemiplegia

    Other causes of paralysis include Nerve diseases such as amyotrophic lateral sclerosis Autoimmune diseases such as Guillain-Barre syndrome Bell's palsy, which affects muscles[] , which can lead to pneumonia, malnutrition, dehydration, and other complications Enteral feedings (tube feedings) should be initiated within 7 days after stroke for patients[] , AH - abductor hallucis muscle, Ampl- amplitude, L- left, R- right Figure 1 - Reduced motor nerves compound muscle action potential and slow conduction velocity with low[]

  • Charcot-Marie-Tooth Disease Type 2S

    One of the authors' patients provided a history of 3 episodes of Bell palsy over 3 years.[] 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[]
