Ectopic mediastinal parathyroid adenomas or hyperplasias account for up to 25% of primary hyperparathyroidism cases. Most abnormal parathyroid glands are found in the superior mediastinum within the thymus and can be removed through a cervical incision; however, a few of these glands are not accessible using standard cervical surgical approaches. Surgical resection has traditionally been performed via median sternotomy or thoracotomy. However, recent advancement in video-assisted thoracic surgery techniques has decreased the need for sternotomy or thoracotomy to remove these ectopic parathyroid glands. Here, we report a successful case of video-assisted thoracoscopic removal of a mediastinal parathyroid adenoma.

OBJECTIVETo discuss the diagnosis and management of asymptomatic primary hyperparathyroidism (PHPT).

METHODSClinical data of 46 cases of primary hyperparathyroidism from January 1990 to December 2006 were retrospectively analyzed. There were 5 cases of asymptomatic PHPT. Three out of the 5 cases obtained the diagnosis by routine health examination and 1 case was misdiagnosed as thyroid tumor before surgery, but was conformed as parathyroid adenoma by intraoperative biopsy. Remaining 1 case was diagnosed because of weakness. The serum calcium and the parathyroid hormone (PTH) levels were elevated in 4 cases, while only 1 being normal range. Unilateral neck exploration was performed in all 5 cases.

RESULTSThere were no operational death, recurrent nerve injury or other complications. All patients had the same pathological diagnosis as parathyroid adenomas. Three cases showed gentle circumoral paresthesia after surgery with normal serum level of calcium, but the symptoms were relieved with oral use of calcium gluconate. Only 1 patient had tetany with the lowest level of serum calcemia at 1.96 mmol/L in 24 h postoperatively. The signs and symptoms were all relieved by intravenous use of calcium gluconate for 3 d after surgery. Remaining 1 case has normal level of serum calcemia after surgery. Time range of following-up for 4 cases was from 2 months to 2 years. The level of serum calcemia was normal for them. One lost following-up.

CONCLUSIONSAsymptomatic primary hyperparathyroidism could be diagnosed according to co-elevated serum calcemia and PTH without typical symptoms. Unilateral neck exploration was the best choice for the patients with accurate imaging localization. Conservative management including adequate hydration, dietary calcium intake and pharmacological approaches could be used for the patients who were unfit for surgery.

OBJECTIVETo investigate the causes of misdiagnosis and the surgical treatment of primary hyperparathyroidism (PHPT).

METHODSThe clinical data of 26 patients with PHPT from July 2008 to January 2013 in The Affiliated Hospital of Chengde Medical College and The Fourth Hospital of Hebei Medical University were retrospectively analyzed, including preoperative diagnosis and operative method. The level of serum calciumion and serum parathyroid hormone (PTH), Ultrasonography, CT, (99)mTc-methoxy isobutylis onitrile ((99)mTc-MIBI) were used in the diagnosis before operation. All patients accepted surgical treatment after the level of serum calciumion decreased to normal.

RESULTSThe level of PTH was examined 10 min after resection, which declined more than 50%. After pathological examination, 23 cases were diagnosed as parathyroid adenoma, 2 cases were parathyroid hyperplasia, and 1 case was parathyroid carcinoma. The level of serum calciumion and serum parathyroid hormone were returned to the normal level after operation. All patients recovered with no postoperative complication.Followed up lasted from 6 months to 5 years, no case recurred.Sixteen cases with symptoms experienced significant improvement in signs, including 10 cases with clinical symptoms completely disappeared.

CONCLUSIONSThe test of serum calciumion and serum PTH, Ultrasonography, CT, (99)mTc-MIBI are helpful to reduce the misdiagnose rate of primary hyperparathyroidism before operation. The examination of serum parathyroid hormone in operation is helpful to reduce the operation range and time.

OBJECTIVE: To summarize and analyze the clinical characteristics of primary hyperpara-thyroidism (PHPT) with normocalcemic parathormone elevation (NPE) after surgical treatment, so as to improve the therapeutic ability and standardized post-operative follow-up of PHPT patients. METHODS: Nine patients who were diagnosed with PHPT in the Department of Endocrinology of China-Japan Friendship Hospital from August 2017 to November 2019 were selected as the subjects. They all developed NPE within 6 months after surgical treatment. The clinical features and outcomes were collected and analyzed retrospectively, in addition, the related literature was reviewed. RESULTS: Clinical features: among the 9 patients, 6 were middle-aged and elderly females and 3 were male. The main clinical manifestations were bone pain, kidney stones, nausea and fatigue except for one case of asymptomatic PHPT. Pre-operative examination showed high serum calcium [(3.33±0.48) mmol/L], low serum phosphorus [0.76 (0.74, 0.78) mmol/L], high 24-hour urinary calcium [8.1(7.8, 12.0) mmol/24 h], obviously elevated intact PTH [(546.1±257.7) ng/L], vitamin D deficiency [25-hydroxyvitamin D₃ (21.0±5.7) nmol/L]. Serum levels of bone alkaline phosphatase [7 patients 41.3(38.6, 68.4) μg/L, 2 patients >90 μg/L] and N-terminal midcourse osteocalcin (>71.4 μg/L) were significantly elevated. The estimated glomerular filtration rate decreased in 2 patients. Imaging examination: 7 patients had osteoporosis. Renal calculi were found in 3 patients by renal ultrasound. Imaging examination of parathyroid glands found definite lesions in all the patients, including 2 cases of multiple lesions and 7 cases of single lesions. TREATMENT AND OUTCOME: two patients underwent parathyroidectomy, while other patients were treated with microwave thermal ablation. PTH increased 1 month after therapy [(255.0±101.4) ng/L], and no recurrent lesions were found by parathyroid ultrasound. After combined treatment with cal-cium and vitamin D for six months, PTH decreased significantly and the level of serum calcium remained normal at anytime during the follow-up period. CONCLUSION The occurrence of postoperative NPE may be related to the higher pre-operative PTH, vitamin D deficiency and lower creatinine clearance. However, NPE may not predict recurrent hyperthyroidism or incomplete parathyroidectomy. Adequate calcium and vitamin D supplementation after surgery seems to be beneficial for patients with NPE. Post-operative follow-up of PHPT patients should be standardized to prevent and treat post-operative NPE.

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.

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.

OBJECTIVE: Through analyzing the 13 cases with primary hyperparathyroidism (PHPT) retrospectively, We detected the reasons of the misdiagnosis and the strategy of diagnosis and treatment for the disease. METHOD: Thirteen cases of clinical materials on PHPT were collected from 2002 to 2012. Initial symptom, laboratory examination and imaging findings were analyzed. Thirteen cases of patients with PHPT all were performed surgery. The period of postoperative follow up was from 3 to 24 months, averaged for 12.2 months. RESULT: Surgeries on 13 patients were successful, including 12 cases of parathyroid adenoma and 1 case of parathyroid hyperplasia. After the operation, blood calcium went back to normal, and the symptoms of bone and urinary tract were relieved. CONCLUSION Initial symptoms of PHPT are predominantly manifested as bone and kidney types. Elevated PTH/blood calcium levels, B-ultrasound/CT and ECT localization are the important diagnosis basis of this disease. Surgical excision of the lesion parathyroid tissue is the most effective treatment.
