Objective To summarize the basic principle of electrical impedance spectrum technology and the latest progress in the diagnosis of thyroid carcinoma. Methods By the domestic and overseas literatures review， medical application and diagnostic prospect in thyroid carcinoma of electrical impedance spectrum were summarized. Results Electrical impedance spectrum was a kind of somatic function imaging， whose measurement results was objective， and it could diagnose thyroid carcinoma in early stage effectively. In addition， it could be used as a complementary form of fine needle aspiration biopsy， improving the diagnostic accuracy rate of thyroid carcinoma， thereby reducing the unessential thyroid operations. Conclusion Electrical impedance spectrum technology is a potentially useful imaging modality for diagnosing thyroid carcinoma in early stage， and functions as a auxiliary clinical diagnosis method for fine needle aspiration biopsy.
ObjectiveTo explore the clinical characteristics, diagnosis and treatment of ectopic thyroid gland (ETG) so as to reduce the misdiagnosis and improper treatment. MethodsAccording to the patients who were definitely diagnosed ETG by pathology from 2002 to 2010 in our hospital, their clinical and pathological data were retrospectively analyzed. ResultsThere were 14 patients, 4 cases of male and 10 cases of female. Five patients had clinical symptoms. Eight cases were diagnosed before operation and six cases were diagnosed by pathology after operation. There were 4 cases were malignancy and 10 were benign. Three cases of differentiated ectopic thyroid carcinoma patients and 1 normal position's thyroid had papillary carcinoma patient accepted TSH suppression treatment after operation, 4 benign patients and 1 ectopic thyroid medullary carcinoma patient accepted levothyroxine substitution treatment after operation, and the other 5 benign patients did not accept any treatment after operation. Nine patients who accepted follow-up in 1-10 years had orthobiosis, and the malignancy patients without recurrence and metastasis. ConclusionsETG usually reveal no any special clinical features. For any masses from root of tongue to mediastinum, especially cervical masses, should be carefully check whether there are thyroid in normal position, and to exclude ETG. The color Doppler ultrasound, thyroid radioactive scanning, thyroid function tests, computed tomography, and fine needle aspiration cytology are all important examination measures. Due to the ETG may occur the same lesions as the normal position's thyroid, so once it is be definitly diagnosed, the treatment should be based on patient's age, position, size, and type of ETG, and nature of the lesions to select follow-up observation, operative treatment, levothyroxine replacement or therapeutic inhibition of TSH, and 131I therapy.
Objective To explore the change of constitution in thyroid diseases of West China Hospital between 2000 and 2012， in order to provide clinical evidence. Methods Clinical data， including gender， age， and pathological diagnosis of patients with thyroid disease who underwent primary thyroid surgery in our hospital from 2000 to 2012 were collected retrospectively and analyzed statistically. Results A total of 9 642 patients were enrolled， including 1 893 male patients and 7 749 female patients. The ratio of male to female patients was 1 to 4.09. In male patients， the proportion of thyroid carcinoma were significantly higher than those of female group （P=0.02）；in male patients younger than 45 group， the proportion of thyroid carcinoma were significantly higher than those of female group （P＜0.01）. There was no statistical difference on the proportion between male and female patients older than 45 group （P=0.90）. Proportion of thyroid carcinoma， especially proportion of papillary thyroid carcinoma （PTC） increased in general. Proportion of Hashimoto thyroiditis （HT） increased in general too. HT with thyroid carcinoma accounted for an increasing proportion of all patients with HT. Proportion of nodular goiter （NG） increased at first and then declined. Proportion of thyroid adenoma （TA） decreased on the whole. Conclusions Proportion of thyroid carcinoma， especially proportion of PTC increase in recent years on the whole in patients underwent surgery. All these changes need to be given sufficient attention.
Objective To summarize the relationship between IgG4 and IgG4 related thyroid diseases. Methods Domestic and international publications involving the pathological features of IgG4-related thyroid diseases and relationship with IgG4 were retrieved and reviewed. Results IgG4-related disease was a newly recognized class of chronic and systemic lymphocytes disease， which may be solitary or involving multiple body organs， as well as thyroid. The expression of IgG4 was found in leisons of Hashimoto thyroiditis， Riedel thyroiditis， and papillary thyroid carcinoma. Conclusions IgG4-related thyroid disease is a new concept of thyroiditis. The knowledge of this new disease will provide appropriate treatment for patients with thyroiditis.
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.
