Uncertain Validity of Papers on Mitral Valve Prolapse with Ophthalmoplegia and on Cardiomyopathy with Hypophosphatemia

Ann Intern Med. 1983;99(2):271. doi:10.7326/0003-4819-99-2-271

This excerpt has been provided in the absence of an abstract.

In 1978 we published a paper reporting three cases of cardiomyopathy associated with hypophosphatemia (1). In 1980 we published a paper reporting seven cases of mitral valve prolapse associated with ophthalmoplegia and other neurologic findings (2). In letters to the editor, authors on these papers have raised questions as to their validity; these letters (3, 4) appear in this issue on page 275, with responses (5) from Dr. John R. Darsee, a co-author on both papers.—THE EDITOR
