OBJECTIVE: To explore the diagnosis and treatment of the ectopic parathyroid gland in the pyriform sinus. METHOD: Retrospectively analysis of 1 case with ectopic parathyroid gland in the pyriform sinus and retrospectively review the past literatures. RESULT: The cases with the ectopic parathyroid gland in the pyriform sinus reported in the past literatures included: 2 with parathyroid gland tissues, 3 with hyperplasia, the other 1 with adenoma. The case reported by us was with adenoma. CONCLUSION The ectopic parathyroid gland hyperplasia in the pyriform sinus is rarely reported before and it usually causes misdiagnosis. Better knowledge of the different position of the ectopic parathyroid gland hyperplasia in the pyriform sinus will help diagnosing and treating it.

BACKGROUND AND OBJECTIVES: Preservation of parathyroid gland during thyroid surgery is important to prevent postoperative hypocalcemia. We evaluated the incidence of unintentional parathyroidectomy during thyroid surgery and postoperative hypocalcemia, and their clinical relationships. MATERIALS AND METHOD: 136 patients who had undergone thyroid surgery were retrospectively followed. We reviewed the pathology specimens to determine the incidence of unintentional removal of parathyroid tissue and inquired the incidence of postoperative hypocalcemia according to the pathology of tumor, the extent of surgery, and the locations of the parathyroid tissues. RESULTS: 27 patients (19.9%) had pathology reports showing parathyroid tissue contained within the thyroidectomy specimen. Unintentional parathyroidectomy was less correlated with postoperative transient hypocalcemia statistically. The postoperative transient hypocalcemia was more frequent after total thyroidectomy for malignant thyroid tumor than hemithyroidectomy for benign thyroid tumor. Most parathyroid tissues were found in extracapsular locations. CONCLUSION: Unintentional parathyroidectomy was reported in 19.9% of the thyroidectomies in our studies. More meticulous dissection of thyroid capsule may be needed, especially during total thyroidectomy for malignant thyroid tumor.

OBJECTIVE: To investigate the clinical feature,diagnostic and therapeutic methods of ultimobranchial fistula and cyst of thyroid. METHOD: Four cases of ultimobranchial fistula and cyst of thyroid in our hospital were reported and the relevant literatures were reviewed. RESULT: The branchial fistula and cyst of four cases were adhered to thyroid,with unclear anatomical landmarks, the function of recurrent laryngeal nerve were bad before the operation in two cases. The nerve of four cases were retained, the function of thyriod and parathyroid gland were normal and no recurrence were found. CONCLUSION Ultimobranchial fistula and cyst of thyroid is rare and is easier to be misdiagnosed and wrong treated. Surgical excision is effective for it and recurrent laryngeal nerve should be protected when performing the operation.

Primary hyperparathyroidism is a rare disease in children and is characterized by conspicuous skeletal and renal changes. A 12 year old male patient presented with symptoms of polydipsia, polyuria, general weakness, nausea, and vomiting which had begun 3 months earlier, and showed typical laboratory findings of primary hyperparathyroidism. Confirmatory diagnosis was made by elevated parathyroid hormone concentration in serum, technetium-thallium subtraction scan imaging method and histopathologic finding of chief cell hyperplasia. The laboratory findings revealed elevated levels of BUN, creatinine and decreased GFR. Kidney biopsy showed typical calcium deposits in tubules with marked tubulointerstitial infiltration. After subtotal parathyroidectomy, clinical findings improved remarkably.

Concurrent thyroid carcinoma and parathyroid adenoma is rare, they can and do coexist. We present here a 63-year old man who had bilateral papillary thyroid carcinoma and a parathyroid adenoma in the right thyroid lobe. Thyroid cancer was confirmed surgically. After the operation, the patient was found hypercalcemie and hypophosphatemia along with an elevated parathyroid hormone (PTH), indicating primary hyperparathyroidism. Also, the parathyroid 99mTc-MIBI scan demonstrated parathyroid adenoma in the right lower pole of the thyroid. The abnormal parathyroid tissue was carried out, and then serum calcium and PTH levels decreased to normal ranges.

A 56 years old female was admitted to our department with complaint of a painless cervical mass. Clinical feature:there was a painless mass above left lobe of thyroid gland, which was about 3.0 cm x 2.5 cm in size, and could move with swallowing action. B-mode ultrasound features: there was a solid mass in left lobe of thyroid gland, which was about 3.2 cm. Nodule was found in isthmus, accompanied with lymphadenovarix on the left neck possibly be MCA. fT3: 4.64 pmol/L, fT4:16.56 pmol/L,TSH:3.74 mIU/L, anti-TG:17.75 U/ml, anti-TPO:40.77 U/ml. Pathological result of the neoplasm: papillocarcinoma. Clinical diagnosis: papillary thyroid carcinoma.

OBJECTIVE: To discuss the role of carbon nanoparticles in the protection of parathyroid during thyroid carcinoma surgery. METHOD: Seventy-two patients with thyroid carcinoma who had initial surgery were randomly divided into two groups: carbon nanoparticles group and the control group. Emulsion of carbon nanoparticles was injected into the thyroid gland of carbon nanoparticles group patients. After thirty minutes,the excision of thyroid carcinoma and VI group neck dissection were performed in carbon nanoparticles group patients, the control group directly underwent operation. The black stained tissue in the dissection specimen of carbon nanoparticles group was separated. The number of total lymph node,metastasis lymph node and parathyroid gland in the tissure black stained or not in two groups were counted respectively. RESULTS: There were 312 lymph nodes in the black stained tissue of central compartment dissection specimen of carbon nanoparticles group. No parathyroid gland was found in the black stained tissue. Fifteen lymph nodes containing four parathyroid glands were found in the non black stained tissue in carbon nanoparticles group while there were 202 lymph nodes containing 13 parathyroid glands in the control group. There were statistical difference between the amount of lymph node in black stain tissue and the specimen of the control group. Parathyroid glands were not stained black,and no parathyroid gland was found in the black-stained tissue. CONCLUSION The carbon nanoparticles could be used to identify the lymph node and the parathyroid gland for protecting the parathyroid gland in thyroid surgery.

OBJECTIVETo probe into an new methods preserving parathyroid gland of patients with thyroid carcinoma.

METHODSThirty-six patients with thyroid carcinoma that primary treated were random divided into two groups: trial group and control group. Emulsion of activated-carbon particles was injected into the thyroid gland of trial group patients. After thirty minutes, central compartment dissection was performed in the all patients. The black stained tissue in the dissection specimen of trial group was separated. Total lymph node, metastasis lymph node and parathyroid gland in the black stained tissue, and non-black stained tissue in the central compartment dissection specimen of trial group and central compartment dissection specimen of control group were counted respectively.

RESULTSNineteen and twenty central compartment dissection was performed in trial group and control group respectively. There are 177 lymph nodes included 83 metastasis lymph nodes in the black-stained tissue of central compartment dissection specimen of trial group. No parathyroid gland was found in the black-stained tissue. Nine lymph nodes included 2 metastasis lymph nodes and 7 parathyroid glands were found in the non-black stained tissue of central compartment dissection specimen of trial group. There were 124 lymph nodes included 80 metastasis lymph nodes and 8 parathyroid glands in central compartment dissection specimen of control group. There are statistic difference between the amount of lymph node in black stain tissue and that of control group (t = 0.340, P = 0.003). Rate of staining lymph node were 95.2 percent.

CONCLUSIONSLymph node of VI group can be stained black by activated carbon particles, and parathyroid gland cannot be stained black. Maybe, parathyroid gland can be preserved by removing the black stain lymph node and retaining the non-black stained tissue.
