Neuromuscular Function in Secondary Hyperparathyroidism

Excerpt

To the editor: In a recent paper (Ann Intern Med 82:474-483, 1975), six cases of osteomalacia, or secondary hyperparathyroidism, or both, with evaluations of neuromusculature function were described. Several questions are appropriate.

There is no evidence given that diabetes mellitus was excluded by the appropriate glucose tolerance test in any of the six patients. This would have been especially useful in Patient 1, who had glycosuria and renal tubular acidosis.

Although it is stated that "motor nerve conduction velocity and distal sensory latency were normal in each of the five patients studied," no specific data are given for each of
