Objective To investigate the clinical diagnosis and treatment for primary hyperparathyroidism with concomitant thyroid diseases. Methods The clinical data of 40 cases diagnosed as primary hyperparathyroidism with concomitant thyroid diseases including manifestation, preoperative qualitation and localization, and surgical treatment and results were retrospectively analyzed. Results The 40 cases were composed of 4 parathyroid adenomas with thyroid papillary carcinomas, 28 parathyroid adenomas with nodular goiters, 6 parathyroid adenomas with thyroid adenomas, 1 parathyroid hyperplasia with nodular goiter, and 1 parathyroid carcinoma with thyroid adenoma. The diagnostic sensitivities of localization for primary hyperparathyroidism with concomitant thyroid diseases by ultrasound, by computerized tomography (CT), and by radioisotope (99Tcm) scanning were 82.5% (33/40), 80.0% (32/40) and 90.0% (36/40), respectively, and the combined sensitivity was 97.5% (39/40). The surgical treatments included resection of parathyroid adenoma with subtotal thyroidectomy in 34 cases, resection of parathyroid adenoma with total thyroidectomy in 3 cases, bilateral exploration of parathyroid with subtotal thyroidectomy in 1 case, and unilateral parathyroidectomy with thyroidectomy and neck lymphonodes clearance in 2 cases. ConclusionFor primary hyperparathyroidism with concomitant thyroid diseases, the sensitivity of preoperative localization could be raised by combining ultrasound, CT with radioisotope scanning, and surgical resection is the main treatment, which includes the main operation of resection of parathyroid adenoma with subtotal or total thyroidectomy.
Vague preoperative localization and ectopic parathyroid often lead to the failure of operation in primary hyperparathyroidism. From Jun 1989 to March 1998, 11 cases of primary hyperparathyroidism had been treated surgically in the general surgery department of our hospital. Of them, 10 cases were operated successfully with the pathological diagnosis of adenoma and one parathyroid removed was reported normal. Preoperative localization, the knowledge of ectopic parathyroids, careful exploration during operation and the postoperative medical treatment are important for the perioperative management. Postoperative followup has emphasized to benefit the treatment in primary hyperparathyroidism.

This is the first successful case expriences,a method of the procurement of the fetal cadavertic multiple argans for transplantation of the pancreas and thyroid-pararthyroid glands was produced. The liver,pancreas,duodenum,spleen,and both kidneys were harvested en bloc by a group of surgeons,and the right hem-ithyroid-parathyroid glands with pedicle of thd blood vessels wre removed by another group.The pancreas together with the spleen were transplanted to a patient having diabetes mellitus. The thyroid-parathyroid glands were given to another case with bypothyroidism and hypoparathyroidism.Both cases had good results.This method had dicreased the warm ischemia of the transplants,and could provide liver,pancreas,spleen,kidneys and thyroid-parathyroid glands to solve the problem of shortage of fetal organs.
Objective To assess the efficacy and safety of Lanthanum Carbonate for hyperparathyroidism in dialysis patients. Methods We searched MEDLINE (1996 to April 2006); EMBASE (1996 to April 2006); Cochrane Central Register of Controlled Trials (Issue 1, 2006); CBM disc; VIP and CNKI. We also checked the references of relevant studies. Randomized controlled trials (RCTs) comparing Lanthanum Carbonate with placebo and standard therapy were eligible for inclusion. Quality assessment and data extraction were done by two reviewers independently. Meta-analysis was conducted using The Cochrane Collaboration’s RevMan 4.2.8. Results Six RCTs were included. Lanthanum Carbonate was found to be more effective than placebo in treating hyperparathyroidism of dialysis patients (OR 4.74, 95%CI 2.66 to 8.45; Plt;0.0001) and the incidence of all drug-related adverse events was similar between Lanthanum Carbonate and placebo-treated group (OR 1.23, 95%CI 0.74 to 2.04; P=0.42). The meta-analysis also showed that the efficacy of treating hyperparathyroidism of dialysis patients was similar between Lanthanum Carbonate and conventional phosphate binders (OR 0.97, 95%CI 0.74 to 1.27; P=0.81) and the incidence of all drug-related adverse events was also similar (OR 1.29, 95%CI 0.62 to 2.47; P=0.49). However, serum calcium level was lower in the Lanthanum Carbonate group than in the conventional phosphate binders group. Conclusion Lanthanum Carbonate is effective and well-tolerated in treating hyperparathyroidism of dialysis patients with end-stage renal disease(ESRD). The incidence of hypercalcemia induced by Lanthanum Carbonate is significantly lower than that of the conventional phosphate binders. However, more large-scale, randomized, double-blinded trials are required to investigate the long-term safety and efficacy of Lanthanum Carbonate.
Objective To summary the experience in diagnosis and managements for primary hyperparathyroidism（PHPT）. Methods The clinical data of 73 patients with PHPT who underwent parathyroidectomy in our hospital from Jan. 2003 to Dec. 2010 were analyzed retrospectively. Results There were 1 case of hyperplasia （1.4%）， 67 cases of adenoma （91.8%）， and 5 cases of adenocarcinoma （6.8%） among the 73 cases of PHPT. The common presentations involved with pain in bones and joints in 63 cases （86.3%）， pathologic fractures in 17 cases （23.3%）， osteoporosis in 59 cases （80.8%）， fatigue in 28 cases （38.4%）， abdominal pain in 4 cases （5.5%）， urolithiasis in 17 cases （23.3%）， malignant hypertension in 1 case （1.4%） who suffered multi-endocrine neoplasm （MEN）Ⅱa， and so on. The preoperativeserum parathyroid hormone （PTH） abnormally elevated in all 73 patients， and serum calcium abnormally elevated in 59 patients （80.8%）， and alkaline phosphatase abnormally elevated in 62 patients （84.9%） before operation. The positive rate of lesion locations by ultrasonography， CT， 99Tcm-sestamibi （MIBI） scan， and the combination of 3 kinds of tests were 82.8% （53/64）， 83.3% （20/24）， 90.2% （46/51）， and 91.8% （67/73） respectively， but 6 cases were not traced preop-eratively. Parathyroidectomy was conducted to all the cases， besides， regional neck lymphadenectomy was performed for those 5 adenocarcinoma cases. Tetany in 16 cases， hoarseness in 2 cases， acute pancreatitis in 1 case， acute left heart failure in 1 case were observed after operation. Sixty nine cases were follow-up for 3-72 months （average 17.3 months）. During the followed-up period， most of them were alleviated from bone pain （43 cases） and fatigue （18 cases）within 1 month. However， the recovery of PTH and serum calcium back to normality were relatively slow. One case ofadenoma recurred， 1 case of adenocarcinoma suffered lung metastasis， 1 case of adenocarcinoma survived for 37 monthsprior to death for postoperative lung and bone metastasis， the other cases （including 1 case of adenocarcinoma developed from adenoma） were still alive and had no metastasis or recurrence by the end of follow-up. Conclusions The symptoms of PHPT vary and lack of specificity， hence， the enhancement of knowledge to this disease and screenings conducted for parathyroid function and serum calcium will increase the rate of diagnosis. Parathyroidectomy is the effective management for PHPT， and preoperatively accurate position contribute to minimal exploration.
Objective To evaluate the diagnostic significance and to analyze reasons of false negative cases forpreoperative ultrasonography， 99Tcm-sestamibi scintigraphy （MIBI scintigraphy）， and CT in primary hyperparathyroidism（PHPT）. Methods Clinical data of 69 patients with PHPT， who underwent operation in Affiliated Shengjing Hospital of China Medical University between Jan. 2003 and Aug. 2012 were retrospectively analyzed. Results There were 76 parathyroid lesions in 69 PHPT patients proved by operation and pathology， including 58 cases of parathyroid adenoma with 60 lesions， 7 cases of parathyroid hyperplasia with 11 lesions， and 4 cases of parathyroid carcinoma with 5 lesions. The sensitivity of ultrasonography， CT， and 99Tcm-MIBI scintigraphy were 81.94% （59/72）， 61.76% （21/34）， and 69.57% （16/23）， the accuracy of 3 kinds of tests were 78.67% （59/75）， 61.76% （21/34）， and 66.67% （16/24）， the positive predictive value were 95.16% （59/62）， 100% （21/21）， and 94.12% （16/17） respectively. There was significant differ-ence only between ultrasonography and CT in sensitivity （P=0.03）， no other significant difference was found （P＞0.05）.Conclusions Ultrasonography is complementary to 99Tcm-MIBI scintigraphy， but CT has little significance in diagnosis of PHPT. Both of ultrasonography and 99Tcm-MIBI scintigraphy should be used before operation routinely to localize parathyroid lesions.
Objective To compare the advantages and disadvantages of using the harmonic scalpel and bipolar coagulation forceps versus harmonic scalpel and conventional clamp-and-tie technique in open thyroid surgery.Methods One hundred patients indicated for thyroid surgery were randomly divided into two groups：the bipolar coagulation forceps group underwent surgery with harmonic scalpel and bipolar coagulation forceps，and the conventional clamp-and-tie group with harmonic scalpel and conventional clamp-and-tie technique，respectively.All operations were performed by the same group of doctors.The total operation time，intraoperative bleeding，mass diameter，postoperative drainage，and surgical complications （postoperative bleeding， postoperative recurrent laryngeal nerve paralysis，seroma，and permanent postoperative hypoparathyroidism） were compared.Results There were 48 valid cases in the bipolar coagulation forceps group， and 49 cases in the conventional clamp-and-tie group. There were no significant differences between two groups patients of age，gender，disease composition，and mass diameter（P＞0.05）.With the same operative approach， the total operation time，intraoperative bleeding，and the incidence of transient postoperative hypoparathyroidism in the bipolar coagulation forceps group were significantly lower than those in the conventional clamp-and-tie group （P＜0.001）.The postoperative drainage in the bipolar coagulation forceps group was more than that in the conventional clamp-and-tie group （P＜0.05）.There was no single case of postoperative bleeding，postoperative recurrent laryngeal nerve paralysis，seroma，and permanent postoperative hypoparathyroidism in both groups.Conclusions The combination of harmonic scapel with bipolar coagulation forceps provides significant advantages over the combination of harmonic scapel with conventional clamp-and-tie technique in open thyroid surgery.
ObjectiveTo explore the safety-related factors for total thyroidectomy in differentiated thyroid carcinoma. MethodsThe clinical data of 72 patients with differentiated thyroid carcinoma treated by total thyroidectomy from January 2002 to January 2010 were retrospectively analyzed, the laryngeal recurrent nerve injury and hypoparathyroidism were observed. ResultsThe incidences of hypoparathyroidism and laryngeal recurrent nerve injury were 15.28% （11/72) and 4.17%（3/72）, respectively. The hypoparathyroidism was significantly related to the thyroid reoperation, the lymph nodes metastases of central compartment, or the extraglandular invasion of the primary tumor (Plt;0.05), but not to the dissection of neck lymph nodes (Pgt;0.05). The laryngeal recurrent nerve injury was not relative to those factors (Pgt;0.05). ConclusionThe safetyrelated factors of total thyroidectomy in differentiated thyroid carcinoma include thyroid reoperation, the lymph node metastasis of central compartment, and the extraglandular invasion of the primary tumor.
【Abstract】ObjectiveTo investigate the effect of xenotransplantation of microencapsulated rabbit parathyroid tissue in different sites in rats for the treatment of hypoparathyroidism. MethodsThe parathyroid glands from Wistar rats were removed to make them aparathyroid. Ultimately, sixteen rats were included because their serum calcium values were continuously below 1.6 mmol/L. We also encapsulated the cultured rabbit parathyroid tissue with alginateBaCl2 microcapsule. According to the transplantation sites, rats were randomly divided into two groups: renal adipose microcapsule group and peritoneal microcapsule group, eight in each group. Encapsulated rabbit parathyroid tissues were then transplanted accordingly to different microcapsule groups. The calcium serum contents were examined on 5，15，25，35，45，55 and 65 d respectively after transplantation and the grafts were observed through electron microscope on the 65 d in particular. ResultsThe calcium contents after transplantation in renal adipose microcapsule group restored to normal and the observation outcomes of grafts showed that they survived well. The calcium contents of posttransplantation in peritoneal group also restored to normal with an exception that it dropped to a level lower than 1.6 mmol/L on the 65 d. Electron microscope also showed that there were necrotic tissues in the center and only a few cells survived on the edge of the grafts. Within peritoneal microcapsule group, the values were significantly lower than others taken at different phases. ConclusionMicroencapsulated rabbit parathyroid tissue that was xenotransplanted into rats can survive and function without administration of immunodepressant. There are significant differences of calcium contents at varying phases between two transplantation sites, which demonstrate that renal adipose may be an optimal site for microcapsule xenotransplantation.
