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.

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.
ObjectiveTo analysis the clinical symptoms, diagnosis, and treatment of primary hyperparathyroidism (PHPT). MethodsA retrospective study was made in consecutive patients with PHPT who performed operation and had integral data between January 2004 to December 2012 in West China Hospital. ResultsThe 136 cases were composed of 52 cases (38.23%) bone types, 17 cases (12.50%) nephrocalcinosis, 7 cases (5.15%) skeletal and renal involvements, 24 cases (17.65%) asymptomatic primary hyperparathyroidism, and 36 cases (26.47%) combined with other clinical symptoms. The preoperative parathyroid hormone (PTH) levels were (106.20±88.88) pmol/L (6.91-390 pmol/L) and serum calcium were (3.12±0.66) mmol/L (2.15-5.77 mmol/L). The coincidence rate between the examinations preoperation and pathology:B type ultrasound was 75.00%, 99Tcm-MIBI scan was 85.29%, ultrasound and 99Tcm-MIBI combined with computerized tomography (CT) scan was 86.76%. Pathology presentation:129 patients (94.85%) were benign lesions, 7 cases (5.15%) were parathyroid carcinoma. Of the 129 patients, 114 cases (95.80%) were single parathyroid adenoma, 5 cases (4.20%) were multiple parathyroid adenoma or combined parathyroid hyperplasia, 10 cases (7.75%) were parathyroid hyperplasia. Of the patients, the PTH level decreased to below normal upper limit within 3 days after surgery in 124 cases (91.18%). One hundred and twenty-four cases (91.18%) were followed-up. The follow-up time was 6-112 months, a median follow-up time was 49 months. Twelve patients (8.82%) were lost to follow-up, 2 patients (1.47%) with carcinoma recurrence, the rest patients without recurrence and metastasis. Three patients (2.20%) with parathyroid carcinoma died. Of the 3 patients, 2 died of systemic metastasis of parathyroid carcinoma in 18 and 23 months after surgery, 1 died of cardiovascular accident in 19 months after surgery. ConclusionSurgical excision of the lesion parathyroid tissue is the most effective treatment for PHPT.
ObjectiveTo compare the efficacy of subtotal parathyroidectomy(sPTX) and total parathyroidectomy (tPTX) plus parathyroid autotransplantation(AT) in treatment of secondary hyperparathyroidism(SHPT). MethodsClinical data of 76 cases of uremia SHPT who underwent sPTX(n=19) and tPTX+AT(n=57) in Xinjiang Armed Police Corps Command Military Hospital and The Xinjiang Uygur Autonomous Region People's Hospital were retrospectively analyzed(from Feb. 2005 to Sep. 2012). ResultsOf the 76 cases, 68 cases(89.5%) got successful surgery and 8 cases (10.5%) suffered non-complete resection, all cases had relief on bone pain, and 14 cases had relief on pruritus(26.9%, 14/52). The values of serum calcium on 1 day, 7 days, and 6 months after operation were lower in tPTX+AT group (P<0.05), and value of iPTH in 6 months after operation was lower too(P<0.05). The operation time, blood loss, hospital stay, and hospital cost in tPTX+AT group were all higher or longer(P<0.05). All of the 76 cases were followed up for 6-18 months(the median time was 8.7 months). During the followed-up, 2 cases died and 2 cases recurred in tPTX+AT group, 1 case died and 7 cases recurred in sPTX group, that the recurrence rate was higher in sPTX group (P<0.05). ConclusiontPTX+AT has lower recurrence rate, but with longer operation time and hospital stay, more blood loss, and expensive cost, so the choice of surgery for SHPT should be based on the comprehensive situation.
ObjectiveTo investigate the significance of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT in the diagnosis of primary hyperparathyroidism, and its relationship with the level of serum calcium (CA). MethodsThe clinical data of 73 patients with parathyroid dysfunction (serum parathyroid hormone (PTH) > 130 pg/mL) were retrospectively analyzed. The 99Tcm-MIBI SPECT double phase imaging were performed in 73 cases, 63 cases underwent cervical B-ultrasound examination, and 16 cases underwent CT examination. According to the serum calcium (CA) levels, the patients were divided into CA < 2.7 mmol/L group and CA > 2.7 mmol/L group, and the postoperative pathological examination and followed-up results were as the standard, the sensitivity, specificity, positive predictive value, and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT for diagnosis of PHPT in different serum CA levels were compared. ResultsThe sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 87.6%, 81.8% and 35.7%, respectively; the specificity was 87.5%, 75.5% and 50.0%, respectively; the positive predictive value was 98.2%, 93.7% and 83.3%, respectively; and the negative predictive value was 46.7%, 33.3% and 10%, respectively. The sensitivity, specificity, positive predictive value and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging and B-ultrasound examination for diagnosis of PHPT were significantly higher than those of CT examination(P < 0.05). The sensitivity, specificity, positive predictive value and negative predictive value of 99Tcm-MIBI SPECT dual-phase imaging for diagnosis of PHPT were higher than those of B-ultrasound examination, but the difference was not statistically significant (P > 0.05). In the CA < 2.7 mmol/L group, the sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 91.1%, 84.7% and 37.9%, respectively; the specificity was 80.2%, 72.9% and 49.7%, respectively; the positive predictive value was 96.8%, 96.0% and 79.4%, respectively; and the negative predictive value was 50.0%, 37.5% and 10.0%. In the CA > 2.7 mmol/L group, The sensitivity of 99Tcm-MIBI SPECT dual-phase imaging, B-ultrasound and CT examination for diagnosis of PHPT was 87.9%, 83.9% and 42.8%, respectively; the specificity was 83.3%, 79.2% and 50.0%, respectively; the positive predictive value was 96.9%, 94.1% and 75.0%, respectively; and the negative predictive value was 50.0%, 40.5% and 20.0%. There were no significant difference in the diagnostic accuracy between the 3 methods and the level of serum CV in different levels. ConclusionsThe diagnostic accuracy of 99Tcm-MIBI SPECT dual-phase imaging and B-ultrasound examination for diagnosis of PHPT patients with PTH > 130 pg/mL (especially parathyroid adenoma) were higher than that of CT examination, and it is not associated with the serum CA concentration.
ObjectiveTo explore and discuss the effects of lanthanum carbonate on serum calcium and phosphorus of continuous ambulatory peritoneal dialysis (CAPD) patients with chronic renal failure receiving calcitriol pulse therapy due to secondary hyperparathyroidism (SHPT). MethodsCAPD patients caused by SHPT in peritoneal dialysis centre of the Qingdao Municipal Hospital of Eastern Hospital from March to June, 2013 were selected and randomly divided into two groups (lanthanum carbonate group and calcium carbonate group). The lanthanum carbonate group were treated with oral lanthanum carbonate and calcitriol pulse therapy, while the calcium carbonate group were treated with calcium carbonate and calcitriol. Change of levels of serum calcium, phosphorus and iPTH were observed and statistic analysis was conducted using SPSS 17.0. ResultsA total of 40 CAPD patients were included, 20 cases in each group. After 12-week treatment, levels of serium phosphate (t=5.095, P=0.000) and iPTH (t=1.225, P=0.000) in the lanthanum carbonate group were significantly lower than those before treatment. The levels of serum calcium (t=1.127, P=0.001) and phosphate (t=2.035, P=0.000) in the lanthanum carbonate group were significantly lower than those in the calcium carbonate group (P < 0.05). ConclusionLanthanum carbonate serves as a useful approach to improve hypercalcemia and the hyperphosphatemia in CAPD patients receiving calcitriol pulse therapy due to SHPT.
ObjectiveTo summarize the research status of normocalcemic parathormone elevation after parathyroidectomy for patients with primary hyperparathyroidism. MethodsThe related literatures on normocalcemic parathormone elevation after parathyroidectomy were collected and reviewed. ResultsMost of the patients with primary hyperparathyroidism received radical treatment postoperation. NPE didn't predict failure of operation. The relationship between normocalcemic parathormone elevation and recurrent primary hyperparathyroidism remained to be further explored. Patients with normocalcemic parathormone elevation after parathyroidectomy had a higher risk of cardiovascular disease. Postoperative vitamin D and calcium supplementation could reduce the incidence of normocalcemic parathormone elevation. ConclusionsThe clinical significance of normocalcemic parathormone elevation is still unknown at present. Further researches of multicenter, huge sample, and long-term follow-up will be necessary.
