Hypocalcemia is relatively uncommon paraneoplastic syndrome. Only one case of hypocalcemia has been reported in a patient with chondrosarcoma. We herein report a case of a 32-year-old woman with metastatic chondrosarcoma with tetany. Her imaging findings revealed multiple calcific metastatic lesions in the lungs, pancreas, left atrium, and pulmonary vein. A laboratory examination showed hypocalcemia with no evidence of any other disease that could induce hypocalcemia. On the basis of the laboratory and clinical findings, we concluded the etiology of her severe hypocalcemia to be excessive calcium consumption by the tumor itself.

The author of Religious Experience and Self-Psychology: Korean Christianity and the 1907 Revival Movement, published in 2016, responds to reviews of his book by Angella Son and Timothy Lee. Son's review pays attention to the current crisis of the decline and stagnation of Korean churches and seeks to devise new strategies for their recovery. Lee states that the book's analysis of the Great Revival Movement of 1907 from a self psychological conceptual framework was careless and speculative. The author reports that their reviews have helped him develop his academic interest in religious experiences and their relationship to psychology and have made his psychohistorical methodology more sophisticated and refined.
