The good news was that Albert "stopped excreting his skeleton into his urine" and within a few months after his parathyroidectomy was able to ambulate and return to a relatively normal life. The bad news was not long in manifesting itself; a year or two later, Albert noticed recurrence of his symptoms and finally agreed to a second operation, six years after the first. Unfortunately, it was unsuccessful and Albert succumbed to the musculoskeletal and metabolic ravages of hyperparathyroidism. A reasonable assumption is that Albert had either "double adenomas," diffuse adenomatous hyperplasia, or multiglandular parathyroid disease. At least two lessons
