Critical reappraisal of referrals to electromyography and nerve conduction studies,

EUROPEAN JOURNAL OF NEUROLOGY, Issue 2 2005
S. Podnar
A large number of examinees referred to electromyographic (EMG) laboratories do not have symptoms or signs suggestive of a peripheral nervous system disorder, and the aim of the present study was to check this. All examinees evaluated by the author in a ,general' EMG laboratory in the first 4 months of 2002 were included. Data on examinees, referral physicians and diagnoses, clinical symptoms and signs, and electrodiagnostic findings were statistically evaluated. Three hundred examinees, 42% men, were included. A neurological diagnosis was provided in 55% of referrals. Electrodiagnostic abnormalities were found in 45% of examinees. Using multivariate statistics, a positive effect of neurological referral diagnosis, history of paraesthesias and of weakness and sensory loss on examination, and a negative effect of history of pain on pathological electrodiagnostic findings were found. Except 20 patients with carpal tunnel syndrome, no patient with normal clinical examination had abnormal electrodiagnostic findings. Our study confirmed the inappropriateness of referrals to electrodiagnostic examination to screen patients for peripheral nervous disorders. We propose electrodiagnostic examination mainly of patients with unequivocal clinical signs of a peripheral nervous system lesion and of patients with typical symptoms of the carpal tunnel syndrome.

Vasculitic neuropathy , electrodiagnostic findings and association with malignancies

ACTA NEUROLOGICA SCANDINAVICA, Issue 6 2007
S. A., ivkovi
Background,,, Vasculitic neuropathies occur in the context of systemic disorders or in isolation. Histopathologic evaluation remains the gold standard for diagnosis, but certain electrodiagnostic findings may heighten suspicion of vasculitic neuropathy and improve the yield of nerve and muscle biopsy. Aim of the study,,, Description of electrodiagnostic patterns associated with vasculitic neuropathies, and a report of a possible association with malignancies. Methods,,, Retrospective review of medical records of patients with histopathologically proven vasculitic and non-vasculitic axonal neuropathies evaluated at the University of Pittsburgh Medical Center from November 1995 to November 2003. Results,,, The most distinctive electrodiagnostic patterns associated with vasculitic neuropathy were mononeuritis multiplex (27.5% vs 4% in controls; P = 0.003) and axonal sensorimotor polyneuropathy with side-to-side amplitude asymmetry (50% vs 32%, P > 0.05). Additionally, six patients (15% vs 2%; P = 0.034) developed various malignancies within 2 years of onset of vasculitic neuropathy. Conclusions,,, While generalized polyneuropathy was the most common presentation of nerve vasculitis, our study affirms side-to-side amplitude asymmetry and mononeuritis multiplex as the most distinctive electrodiagnostic features. The frequent occurrence of malignancies suggests a possible association with the vasculitic neuropathy and warrants additional investigation. [source]
