- Pheochromocytoma is a catecholamine producing turnor and raise with less than 0.1% of hypertensive patients. It is developed, most commonly, in sporadic pheochromocytoma or multiple endocrine neoplasia type 2. Therefore, when hypercalcitoninemia is found in a patient with pheochromocytoma, the possibility of multiple endocrine neoplasia type 2 or the ectopic secretion of calcitonin must be considered. Recently we experienced a 45 year old male patient with sporadic pheochrornocytoma. He also had hypercalcitoninemia and normocalcemia. After the removal of pheochromocytoma, serum calcitnnin level returned to normal. Secretion of calcitonin was confirmed by immunohisto- chemical stain.

- Tuberculosis the thyroid gland occurs only rarely and a few records are available in Korea, despite of high prevalence of tuberculosis. The authors experienced a case of young woman with tuberculosis of the thyroid gland and meninges. Tuberculosis of the thyroid gland was confirmed by demonstration of acid-fast bacilli and granuloma with caseation necrosis on surgical specimen. Description of case profile and a brief review of literature are made.

Abstract

- Periodic paralysis associated with thyrotoxicosis is characterized by intermittent flaccid paralysis of the skeletal muscle. The paralysis usually involve the skeletal muscle of the limbs, especially lower extrimities. In general, sensory function is intact. Involvement of respiratory, ocular or bulbar muscles is very rare, but bulbar and respiratoy invelvement may prove fatal. It is very rare a case that has severe clinical manifestation such as cardiac arrest. We report a case of thyrotoxic hypokalemic periodic paralysis presenting as cardiac arrest.

Abstract

- Hyperthyroidism is a well known cause of atrial fibrillation. It is also known that control of hyperthyroidism can usually curb thyrotoxic atrial fibrillation and restore sinus rhythm. In this study, 282 patients with hyperthyroidism were investigated to quantify the incidence of atrial fibrillation, and to identify the vulnerable groups. In addition, we compared two groups of subjects with atrial fibrillation-one group with hyperthyroidism and the other group without - to study their reversion rate to sinus rhythm. Lastly, we investigated the factors affecting reversion to sinus rhythm in patients with thyrotoxic atrial fibrillation.The results were follows;1) Among 282 patients with hyperthyroidism, 35 cases(12.4%) had atrial fibrillation. Atrial fibrillations were more prevalent among male patient(19.4%) and elderly patients(42.9%) than female patients(10.0%) and young patients(10.0%).2) Reversion to normal sinus rhythm in patients with thyrotoxic atrial fibrillation(39.3%) was significantly higher than that in patients without hyperthyroidism(17.4%, p<0.001).3) Reversion to normal sinus rhythm was achieved within 28 weeks from the beginnig of antithyroid treatment in patients with thyrotoxic atrial fibrillation. Although there were no significant differences in mean age, sex ratio, and initial and follow-up thyroid hormone levels between the reversion group and non-reversion group, associated heart diseases were more prevalent in the latter group(18.2% vs. 47.1%).It can be concluded that thyrotoxic atrial fibrillations were more common in male patient and elderly patient groups, and could be frequently reverted to normal sinus rhythm by antithyroid treatment. We also suggest that the duration of artrial fibrillation(from intial onset of the condition), and associated heart diseases, may be important predictive factors for the reversion of atrial fibrillation in patients with hyperthyroidism.
