To analyze the clinical profile and therapeutic effect of re-operation treatment in uremic patients complicated with persistent secondary hyperparathyroidism(SHPT)after parathyroidectomy with autotransplantation.Twelve persistent SHPT patients who were treated with reoperation of paramyroidectomy(PTX)were enrolled in this study during the period from Jan 2014 to Jul 2017 in our hospital.We evaluated the location of the remaining parathyroid glands by ultrasonography,dual-phase 99 Tcm-sestamibi scintigraphy,CT and MR imaging of the neck before the operation.We resected the parathyroid gland tissue in situ,and the ectopic parathyroid glands hiding in thymus,mediastinal,tracheal esophageal groove,thyroid gland and other locations in the neck.During the surgery,nanocarbon imaging was used to help identify the parathyroid gland and parathyroid hormone assay(IOPTH)was measured at the end of the surgery.We observed the changes of clinical symptoms after the surgery and collected blood parameters including serum intact aramyroidhomone(i-PTH),calcium(Ca),phosphoms(P),calcium and phosphorus product before and after surgery.Complications and failure were also analyzed.All the 12 patients underwented successful operation.The postoperative pathological results were hyperplastic parathyroid glands tissue.22 parathyroid glands were resected,among which 14 were located at the neck in situ,8 were ectopic,i.e.,located at thymus in 4 cases,superior mediastinum in 2 cases and thyroid parenchyma in 2 cases.The clinical symptoms were significantly improved including osteoarthritis,skin itching and limb weakness.The levels of serum iPTH,calcium,phosphorus and calcium and phosphorus product were significantly lower than those before operation(<0.05).Ten patients presented hypocalcemia after surgery and the level of calcium returned to normal after supplement of calcium.Temporary injury of laryngeal nerve was found in4 cases,but there was no patient with transient bucking,dyspnea or death.No recurrence was found during 1 year follow-up.It was very important to locate the residual parathyroid gland accurately with a variety of imaging methods in uremic patients complicated with persistent or recurrent SHPT when they needed re-operation.Surgeons should explorate ectopic parathyroid gland according to the concept of the superior mediastinum dissection and the central compartment neck dissection.Meanwhile,the use of nanocarbon assisted parathyroid gland negative imaging and rapid IOPTH can significantly improve the success rate of surgery and reduce surgical complications.

Parathyroid adenoma is a major cause of primary hyperparathyroidism. Treatment usually involves the surgical removal of one or more parathyroid glands. However, specific localising techniques have boosted the development of nonsurgical, minimally invasive procedures, such as percutaneous radiofrequency ablation (RFA) under ultrasonographic guidance, which are gaining popularity as a method of treatment. This paper reports two male patients who presented with hypercalcaemia (highest serum calcium level 4.56 mmol/L and 4.57 mmol/L, respectively) and hyperparathyroidism (highest serum parathyroid hormone [PTH] level 772 ng/L and > 1,900 ng/L, respectively) due to solitary parathyroid adenoma. Four days after percutaneous RFA, the serum calcium levels in both patients decreased and PTH levels showed a significant decreasing trend. Both patients recovered well with normal levels of calcium and improvement of symptoms. Thus, we conclude that RFA may be a safe and effective therapeutic option in the treatment of parathyroid adenoma.

OBJECTIVETo discuss the clinical characteristics of primary hyperparathyroidism (PHPT) with kidney stones.

METHODSThe clinical data of 23 cases undergoing diagnostic evaluation and surgery for PHPT combined with kidney stones between January 2004 and February 2012 was retrospectively analyzed. The 23 cases had undergone preoperative parathyroid neck color ultrasound, CT or (99)mTc-methoxy isobutyl isonitrile ((99)mTc-MIBI) diagnosis. The surgical treatment included parathyroid disease and kidney stones. The intravenous calcium, phosphorus and serum intact parathyroid hormone (iPTH) levels, 24 hours urinary calcium concentrations were measured 3 days before and 7 days after surgery.

RESULTSThere were 8 male and 15 female patients. The stone diameter were (3.2 ± 0.7) cm (range 2.1-4.0 cm). All patients did both parathyroid surgery and kidney surgery. The statistical discrepancy of serum calcium (there were (3.31 ± 0.39) mmol/L before surgery and (2.12 ± 0.18) mmol/L at 7 days after surgery, t = 11.26), serum phosphorus ((0.70 ± 0.09) and (1.21 ± 0.21) mmol/L in before and after surgery respectively, t = 10.53), iPTH (there were (28.8 ± 10.0) pmol/L before surgery and (3.6 ± 2.6) pmol/L after surgery, t = 12.83) and 24-hours urine calcium (there were (7.2 ± 3.1) mmol/d before surgery and (3.6 ± 2.5) mmol/d after surgery, t = 8.81) before and after the operation was significant (all P < 0.01). PTH concentration with serum calcium concentration correlation coefficient was r = 0.59 (P < 0.01). Eighteen patients (78.3%) had solitary parathyroid adenomas, two patients (8.7%) had multiple parathyroid adenomas, and three patients (13.0%) had multiglandular hyperplasia confirmed at surgery and histology. During follow-up, 8 patients had stone recurrence and 3 patients were did operation again to deal with renal stone within 2 years. Among them, 7 cases were normal, 1 case of parathyroid adenomas recurrence and reoperation.

CONCLUSIONSThe parathyroid operation may reduce the calculus recurrence remarkably. Early diagnosis and treatment of primary hyperparathyroidism is helpful to reduce the calculus recurrence and preserve the renal function.

Metastatic pulmonary calcification refers to calcium deposition in the normal pulmonary parenchyma and this deposition is secondary to abnormal calcium metabolism. The most common radiologic manifestation consists of poorly-defined nodular opacities that are mainly seen in the upper lung zone. We present here a case of metastatic pulmonary calcification that manifested as atypical, dense, calcium deposition in airspaces within the previously existing consolidation in the bilateral lower lobes, and this process was accelerated by pneumonia-complicated sepsis in a patient with hypercalcemia that was due to hyperparathyroidism.

It has been reported that the common sites of brown tumors are the jaw, pelvis, ribs, femurs and clavicles. We report our experience in a case of brown tumor of the patella caused by primary hyperparathyroidism. An initial radiograph and CT showed an osteolytic lesion and MR images showed a mixed solid and multiloculated cystic tumor in the right patella. One month after the parathyroidectomy, rapid bone formation was observed on both radiographs and CT images.

OBJECTIVETo study the clinical features of hyperparathyroidism due to parathyroid tumors, and evaluate the efficiency of surgical management.

METHODSTwenty-two patients with hyperparathyroidism resulted from parathyroid tumors were reviewed. The age ranged from 32 to 79 years, 9 males and 13 females. Recurrent laryngeal nerve was routinely exposed, and procedures were performed in normal tissue in initial surgery. Additional selective neck dissection of levels II, III, IV, and VI was taken in the cases with recurrent cancer. Local flaps were used to repair the esophageal defects after resecting tumors. The recurrent laryngeal nerves of 4 cases had to be sacrificed because they were embedded in the tumor tissues despite the nerves had normal function before operation. Prophylactic tracheostomy was performed in 5 cases.

RESULTSEight cases were identified pathologically as parathyroid carcinoma, of them four with neck metastasis, and 14 cases as parathyroid adenoma after surgery. Their PTH dropped to normal level within two hours after surgery and hypercalcemia disappeared in two days postoperatively. The PTH and serum calcium were in normal range during the follow-up of 12 to 40 months. Recurrence occurred again in two cases in 6 and 8 months after the removal of the recurrent tumor tissues respectively. Esophageal fistula, chylous fistula and dehiscence of sternotomy developed in three cases separately. The tracheostomy was removed in four cases two weeks after operation and in one case six weeks after operation. One patient with parathyroid adenoma died of hypocalcemia about two weeks after operation and another one with recurrent parathyroid carcinoma also died of hypercalcemia 52 months after revised surgery.

CONCLUSIONExtended resection of tumor and intraoperative PTH assay were strongly suggested for the managements of both benign and malignant parathyroid tumors.

OBJECTIVE: To investigate the clinical manifestations and diagnostic method of hyperparathyroidism due to parathyroid tumors and to evaluate the intra-operative detection of parathyroid hormone in surgical treatment. METHOD: Thirty-seven cases with functional parathyroid tumors from January 2003 to October 2012 were retrospectively analyzed. The clinical manifestation, examination and operation method, changes of parathyroid hormone before and after operation were collected. RESULT: All cases were definitely diagnosed before operation. The sensitivity and the positively predictive values of neck ultrasonography were 86.5% and 97.6% respectively, and the same data of Tc-99m-MIBI was 97.2% and 100.0%. The PTH levels declined by 84.9% ten minutes after tumor resecting compared with the level before operation. The serum calcium and PTH returned to normal levels and symptomatic relief occurred after operation. CONCLUSION Recurrent bone disease, long-term urinary calculus and obscure gastrointestinal symptoms were common symptoms of hyperparathyroidism due to parathyroid tumors. The neck ultrasonography and Tc-99m-MIBI were suitable for location of parathyroid tumors. Surgical operation was an effective treatment for parathyroid tumor. Intra-operative PTH assay would be able to ensure the radical excision and the operative safety for functional parathyroid tumors.

OBJECTIVE: To investigate the clinical manifestation, diagnosis, treatment of parathyroid occupying lesions. METHOD: The clinical data of 26 patients with parathyroid occupying lesions between January 2003 and October 2012 at Dalian Central Hospital were retrospectively analyzed. RESULT: There were 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma, 13 cases of parathyroid cysts in this study. All the cases,except 13 cases of cysts, are accompanied by symptoms of hyperparathyroidism. The symptoms were as follows:26 cases of neck lump, 11 cases of osteoporosis/osteitis fibrosa cystica,9 cases of urinary symptom, 8 cases of digestive symptom. Serum calciumion level and serum parathyroid hormone(PTH) level were examined qualitatively before operation. Ultrasonography, CT, MRI were used in diagnosing and locating parathyroid occupying lesion before operation. 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts with preoperative and postoperative diagnosis coincidence rate was 0 (0/2), 91% (10/11), 69% (9/13). All patients were treated with operation. 2 cases of parathyroid cancer survived with out recurrence during follow up for 17 months and 27 months after operation. 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts were treated with operation,achieved complete remission and the outcome was no recurrence. CONCLUSION There lack of specific clinical symptoms of parathyroid occupying lesions,neck lump are common manifestations. Examination of serum calcium and PTH level together with ultrasonography, CT, MRI, 99mTc-MIBI is helpful to diagnose parathyroid occupying lesions. Parathyroid cancer preoperative diagnosis is difficult . Parathyroid occupying lesions determine the diagnosis depends on pathology. Surgery should be done as primary treatment.
