ABSTRACT
Objective To investigate the effect of operation for hyperthyroidism assoiciated with hypokalemic periodic paralysis(HPP).Methods We retrospectively analysed the clinical data of 121 cases of hyperthyoidism associated with HPP.Among them 81 patients received subtotal thyroidectomy after taking Lugol solution for 2 weeks;40 patients received non-operative therapy.Results The plasma potassium,T3,T4,TSH and BMR levels of patients who received subtotal thyroidectomy were all normal 1 week post-operatively,Only 2 patients suffered symptoms of relapse at follow up of 0.5-10 years,with cure rate of 97.5%;8 of the patients who received non-operative therapy recovered,with cure rate of 20.0%.Conclusions Operation for hyperthyroidism associated with HPP could cure HPP and hyperthyroidism simultaneously.The therapeutic efficacy of operation is rapid and stable,and is markedly better than that of non-operative therapy.
ABSTRACT
Objective To study new preoperative preparation for primary hyperthyroidism. Methods Before operation, Lugol solution was used(5～10 getts/time, 3 times/d) for 10 days. On the 7th day, dexamethasone 20?mg was added to 5%～10% glucose solution 500?ml was consecutively used for 3 days before the operation. Results FT 3 fell to normal value after dexamethasone 20?mg was used once, and FT 4 fell to normalvalue after dexamethasone used 3 days. There was no any complication, such as thyroid crisis occurring in this series. Conclusions Dexamelhasone applied before operation as the preoperative preoparation for primary hyperthyroidism is testified a safe and effective method.
ABSTRACT
Objective To investigate the effects of propranolol on thyroid hormone in patients with hyperthyroidism after operation. Methods Forty patients with mediate or severe degree hyperthyroidism undergoing operation were randomly divided into four groups according to anesthesia and whether to take propranolol in perioperative period: Group A:propranolol plus general anesthesia; Group B: general anesthesia; Group C:propranolol plus cervical plexus blocking; Group D: cervical plexus blocking. The consecutive changes of T 3, T 4,rT 3 and TSH were measured with radioimmunological assay pre and post operatively. Results The level of serum T 3 in all groups decreased 1～7 days after operation. The decrease in serum T 3 leves was most significant 3～7 days after operation in group A and C, 1～3 days after operation in proup B and D(P
ABSTRACT
Objective To study the diagnosis and treatment of hyperthyroidism companied with thyroid carcinoma . Methods The clinical data of 11 cases of hyperthyroidism with thyroid carcinoma were retrospectively analysed. Results 9 of 11 cases were diagnosed preoperatively,and comfirmed by frozen section intra-operatively and underwent suitable operation. In the other two cases the final diagnosis was made by pathological examination postoperatively, and re-operation was performed on 1 case . All the patients were followed up for 1～16 years and neither hyperthyroidism nor thyroid carcinoma recurred. Conclusion It is difficult to make diagnosis of hyperthyroidism with thyroid carcinoma preoperatively. B mode ultrasonography may find some nodes in enlarged thyroid; but fine needle aspisation biopsg(FNA) has high false negative diagnostic rate. Intra-operative frozen section examination is important in the diagnosis of hyperthyroidism with thyroid carcinoma .
