    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.

    Notes: Abstract Papillary carcinoma of the thyroid is a common thyroid malignancy with a relatively good prognosis. However, distant metastases may develop and become threatening, particularly to older patients, in a more aggressive manner. We report herein the clinical, radiological, and pathological findings of a patient with papillary thyroid carcinoma who had a solitary cerebral metastasis. The patient had been suffering from depression and had already undergone a hemithyroidectomy for primary thyroid carcinoma, and was known to have metastatic thryoid carcinoma of the lungs and bone. After the removal of the remnant thyroid gland prior to radioiodine (131I) therapy, he developed additional problems related to depression. Electroencephalography played an important role in identifying suspected brain metastasis and computed tomography demonstrated a space-occupying lesion in the left cerebral hemisphere. Consequently, an early removal of intracranial mass could be performed without any further life-threatening complications. Moreover, after removal of the brain mass the patient's depression improved immediately without the use of any antidepressants. This case report indicates the possibility that a patient's depression might be associated with brain metastasis from papillary thyroid carcinoma, and also suggests that an early diagnosis with the appropriate surgical management of a brain metastasis followed by radioiodine therapy could be valuable for achieving a prolonged disease-free period.

    Notes: Abstract A total 847 consecutive patients with Graves' disease who underwent thyroidectomy between 1965 and 1990 were found to have a 4.3% incidence of coincident carcinoma of the thyroid. In 68.2% of these cases the tumors were less than 1 cm in diameter and were detected in only 7 patients (19.4%) prior to surgery. Dissection of the regional lymph nodes was necessary in only 11 patients. A review of the patients in 1990 revealed no carcinoma-related deaths with metastases occurring most commonly in the patients with larger tumors and in those whose cancer had been detected prior to thyroidectomy. Although the detection of potential tumors occurring with Graves' disease using preoperative echogram may be of interest, our results suggest that occult micro-carcinoma occurring coincidentally with Graves' disease is not clinically significant as it did not cause any recurrence in this study. Moreover, there was no evidence to suggest that Graves' disease was associated with the increased or rapid growth of these tumors.

    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.
