    Notes: Abstract From 1982 to 1985, twenty-nine patients with suspected hyperparathyroidism were examined using201Tl-99mTc subtraction scintigraphy (Tl-Tc), computed tomography (CT) and ultrasonography (US). For diagnosing neoplasm (adenoma or cancer), the sensitivities of the three procedures were 80 per cent or more, with no statistically significant differences. For diagnosing hyperplasia of the parathyroid glands, CT scan had the highest sensitivity (47 per cent). The most frequent source of error was minimally enlarged glands, weighing less than 500 mg. The second highest source of error was thyroid nodules, such as adenomatous goiter or cancer. Serum calcium and c-PTH levels were significantly higher in those with a parathyroid neoplasm than in those with hyperplasia (p〈0.01, p〈0.05, respectively). We concluded that hyperplasia is less easy to detect than neoplasm, and CT scan is superior to Tl-Tc or US scan for localizing hyperplasia.

    The problems encountered in the surgical management of primary hyperparathyroidism (1991)

    Notes: Abstract The problems encountered in the diagnosis and treatment of primary hyperparathyroidism were studied in 69 cases. The accuracy of imaging for hyperplasia was less than that for adenoma or carcinoma and the major causes for multiple operations were a failure to locate the four glands and mediastinal adenoma. The intravenous administration of high doses of calcitonin could reduce the serum calcium level of patients in hypercalcemic crisis. Carcinoma required ipsilateral modified radical neck dissection because of lymph node metastases, and non-medullary thyroid carcinoma was often associated with primary hyperparathyroidism. We found removal of the parathyroid adenoma and biopsy or extirpation of only one macroscopically normal gland to be a fully satisfactory procedure after bilateral neck exploration and attempting to identify at least four glands.

    Myasthenia gravis with thymoma associated with occult thyroid carcinoma (1992)

    Notes: Abstract We report herein a case of myasthenia gravis associated with thymoma and occult thyroid carcinoma with metastasis to a cervical lymph node, which was treated in two stages by a total thymectomy and radical dissection of the bilateral neck after a total thyroidectomy. A 48 year old woman was admitted with right blepharoptosis and hypodynamia of the proximal muscles. After various examinations, a diagnosis of myasthenia gravis was made. The association of thymoma was clarified upon CT scanning and a total thymectomy performed. However, after surgery, swelling of the cervical lymph nodes became apparent and a biopsy revealed metastasis of thyroid carcinoma in the lymph nodes. A diagnosis of occult thyroid carcinoma with metastasis to a cervical lymph node was subsequently made and a total thyroidectomy and radical dissection of the bilateral neck performed 37 days after the total thymectomy. The patient's postoperative course was uneventful and for the time being, no recurrence is expected. It is considered better to perform two-stage operations for easier and safer postoperative management when myasthenia gravis associated with occult thyroid carcinoma is treated, although it depends on the development of thyroid carcinoma being occult.

    Primary squamous cell carcinoma of the breast in a pregnant woman: Report of a case (1993)

    Notes: Abstract Although reports on primary squamous cell carcinoma of the breast have been increasing in number, the morbidity rate of the disease is comparatively low. Its onset in pregnant women, especially, is quite rare. We herein report a case of primary squamous cell carcinoma of the breast in a pregnant woman. A 33-year-old woman was admitted with a lump in the right breast and an abnormal bloody nipple discharge. The breast mass was 5.6×5.4 cm in size, and both ultrasonogram and CT scanning showed that it consisted of a cystic tumor for the most part. A large amount of bloody cystic fluid was aspirated by fine-needle aspiration; squamous cell carcinoma of the breast was suspected by a cytological study on the fluid. Twelve days after an induced abortion was performed, a modified radical mastectomy was carried out. Histological findings of the resected specimen demonstrated that the tumor was squamous cell carcinoma which had been well differentiated with partial keratinization and cancer pearls. Noninvasive ductal carcinoma was also observed in a very small region of the specimen, which indicated that the tumor was probably originally adenocarcinoma which later transformed into squamous cell carcinoma.

    Diagnostic usefulness of201T1-chloride scintigraphy for preoperative localization of parathyroid tumors (1981)

    Notes: Abstract 201T1-chloride scintigraphy was performed in 10 patients with hyperparathyroidism to assess the localization of abnormal parathyroid glands. This approach proved to be useful in 8 of 10 patients. In particular, an intramediastinal ectopic gland was clearly demonstrated in one patient. Several disadvantages were noted, however,201Tl-chloride scintigraphy could be the first choice for preoperative localization of abnormal parathyroid glands. If a negative image is obtained, further examinations such as arteriography or parathyroid hormone assay by selective venous blood sampling should be done.

    Clinicopathological studies on thyroglossal duct remnant (1979)

    Notes: Abstract The clinicopathological findings in 48 cases underwent complete surgical excision of epithelial tissue of the thyoglossal duct remnants were reviewed. Simple incision of the cyst does not seem to have any therapeutic value and would be followed frequently by recurrence. The widely used Sistrunk procedure2,6 surgical excision of the central portion of the hyoid bone together with fibrous tract extending to the base of tongue, seems to be not warranted in some cases so long as complete eradication of the epithelial tissue can be made.

    Reconstruction of the carotid artery using a temporary shunt during an operation for advanced thyroid carcinoma —A case report— (1988)

    Notes: Abstract A case of a patient who required reconstruction of the carotid artery during a radical operation for advanced thyroid cancer is reported herein. The patient, a 64-year-old female who had had three previous operations for thyroid cancer, underwent a two-stage operation. In the first stage, the left cervical lymphnodes were dissected, but as a large metastatic node invading the left carotid artery could not be completely removed, some carcinoma tissue was left attached to the wall of the artery. The second stage involved a temporary shunt being set up between the common carotid artery and the internal carotid artery following heparinization, after which the invaded portion was resected, and the defect patched with a saphenous vein graft. Monitoring with a Doppler flow-meter and EEG were conducted throughout the operation. At present, cancer has recurred in the left submandibular and supraclavicular regions.

    An evaluation of the intraoperative staining technique using methylene blue for the detection of hyperplastic parathyroid glands (1988)

    Notes: Abstract Intraoperative staining with methylene blue was employed during parathyroid surgery on 50 glands from 13 patients, 5 with primary and 8 with secondary hyperparathyroidism. Forty-seven out of the 50 glands (94 per cent) were visualized by the staining and 2 out of the 13 patients were revealed to have supernumerary parathyroid glands. Since we started using this technique, there have been no cases of persistent hypercalcemia. The results of this study support the clinical usefulness of this staining procedure for detecting hyperplastic parathyroid glands in both primary and secondary hyperparathyroidism.
