“…Subsequent work on this point has given rather conflicting results. Pollini (24), Haberfeld (25), Harvier 12and Erdheim (26), support Yanase, but Oppenheimer (27), Jorgensen (28), Grosser and Betke (29), and Auerbach (30), as a result of their pathological investigations, do not find any evidence that hawmorrhage in the parathyroids is responsible for the condition. Harvier found not only evidence of haemorrhage, but also of fibrosis of the parathyroids in some of his cases.…”
