Eighteen patients with primary hyperparathyroidism were treated by one of the authors (SKO) from 1981 through 1988 at the Department of Surgery, Seoul National University Hospital and the data were analyzed retrospectively. Eighteen patients comprised 6 males and 12 females, with the male to female ratio of 1 to 2. The age distribution was between 18 and 64 years. The chief complaints were associated with skeletal symptoms in 9 urinary symptoms in 5, and neurologic manifestation in 1 patient. There were 3 patients with asymptomatic hypercalcemia. All patients showed hypercalcemia and hypophosphatemia was found in 11 patients. Serum PTH level was elevated in 13 cases. performing preoperative localization with computed tomorgam, ultrasonogram and thallium-technetium subtraction scan, positive localization was made in 62.5% (10/16), 53.8% (7/13) and 85.7% (12/14), respectively. one patient, angiography and selective venous sampling were peformed and positive localization was made. All patients were treated by surgery. There were 17 patients with solitary adenoma and one with double tumors. Pathologic findings revealed adenoma of the parathyroid in all patients except one which was proved later to be carcinoma. There were no recurrent cases except one with carcinoma. There were no postoperative complications. primary hyperparathyroidism is a very rare disease in Korea. Causes of primary hyperparathyroidism in our study was confined to tumors of the parathyroid, such as adenoma and carcinoma.There was no hyperplasia causing primary hyperparathyroidism. Thallium-technetium subtraction scan was proved to be the best method for localization of the parathyroid tumors. Excision of the tumor with involved parathyroid followed by frozen-section biopsy of the univolved parathyroid was the best way to treat primary hyperparathyroidism in our study.

Current medicine is a living science which is developing rapidly. It seems that coming up with the rapid development of medicine by the conventional educational system has some limitation, since the development is too rapid. Development of internet-based medical educational program(IMEP) would be a kind of solution. To overcome the limitation, we developed an IMEP which could be used either on the File Transfer Protocol(FTP) or World Wide Web(WWW), and tested whether it would meet the requirements of our purpose. The IMEP of ours functioned satisfactorily. IMEP for WWW was accessed by far more frequently than IMEP for FTP by the visitors. Frame-typed HTML files were displayed 2 times faster than plain HTML files. HTML files which hid the graphic data behind were displayed more quickly than conventional HTML files. CGI programs were considered to be necessary tools for bidirectional communications between the host and clients on the IMEP. A small PC server worked properly as well as a large server when the access was confined to a small number of visitors. We concluded that IMEP was an excellent adjuvant method of education to make up the gap between the conventional educational system and the rapid development of medicine.
