To the Editor:—
I must take issue with the usage of the word "neuromyopathy" in "Tetanic Neuromyopathy and Renal Failure" by R. W. Ewer et al in the June 28 issue (192:1117-1120, 1965). The authors define the terms "tetanic," "myoclonus myospasm," and "myospastic state" but leave the meaning of the word "neuromyopathy" to the reader to interpret.Most workers in neuromuscular disease define "myopathy" as any disease of muscle, and in doing so imply that if the muscle were to be examined by proper histological techniques, a disorder of muscle would be found. "Neuromyopathy" is used when examination, usually done either by electromyography and nerve-conduction studies or histology, reveals a disorder of both the muscle and the peripheral nerve or lower motor neuron. Motor manifestations of central nervous system disorders such as myoclonus, Parkinson's disease, dystonia musculorum deformans are called neither myopathies nor neuropathies.The authors did not report
