甲状腺外科疾病常见，有许多进展和进步，这是热点； 但许多治疗意见不一，分歧极大，长久难以统一，故又有许多难点
Objective To investigate the financial burden of in-patients with thyroid diseases in the West China Hospital in Chengdu, Sichuan province, from January 2011 to December 2012, so as to provide baseline data for further research. Methods The data of in-patients (who had been discharged from the department of endocrinology and metabolism or discharged after being transferred to other departments for diagnosis and treatment in the West China Hospital in 2011) were collected from the Hospital Information System (HIS) of the West China Hospital, including basic information, initial diagnosis when the patients were discharged, hospital costs, the information about whether the patients had been registered the insurance in hospital, etc. We classified diseases according to ICD-10 based on the initial diagnosis when the patients were discharged on the first page of case reports. The data were input using Excel 2010 software, and statistical analysis was performed using SPSS 13.0 software. Results The results showed that: a) in 2011, 205 person-times were hospitalized in the department of endocrinology and metabolism, of which, 84 were male and 121 were female, with mean age of 45.3±15.7 years; b) for patients with thyroid diseases, median hospital stay was 10 days, the average cost of hospital stay for each patient was RMB 2 881.43 yuan, most of which was for lab tests and examination; c) the person-times of patients with hyperthyroidism was 162, accounting for 79.5% of the total of thyroid diseases, median hospital stay was 10 days, and the average cost of hospital stay was RMB 2 958.36 yuan; and d) there was no association between the number of hyperthyroidism complications and hospital stay and costs. Conclusion Thyroid diseases are a commonly-seen disease in the department of endocrinology and metabolism, of which, hyperthyroidism accounts for the most. There is no association between the number of hyperthyroidism complications and hospital stay/costs.
ObjectiveTo explore the diagnostic value of sonography in thyroid imaging reporting and data system (TI-RADS) for thyroid nodules. MethodsA total of 292 patients (423 nodules) underwent thyroid examination with high frequency ultrasound. The results were retrospectively compared with histopathological diagnosis and TI-RADS lexicon. ResultsThe category 1-5 of 423 thyroid nodules were evaluated by using TI-RADS, and it’s frequency of being malignancy rate was 0(0/129), 6.3%(11/176), 33.3%(10/30), 86.8%(46/53), and 100% (35/35), respectively. The sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for benign thyroid nodule of ultrasound in TI-RADS was 96.3%（309/321）, 83.3%（85/102）, 93.1%（394/423）, 94.8%（309/326）, and 87.6%（85/97）, respectively. Positive likelihood ratio, negative likelihood ratio, and Youden’ index was 5.77, 0.04, and 79.6%, respectively. The benign and malignancy nodule of TI-RADS category were statistically difference in shape, margin, echogenicity, echotexture, composition, and calcification inside the nodule (Plt;0.001). ConclusionsTI-RADS lexicon has an important guiding value for clinical diagnosis and treatment in ultrasound examination of thyroid nodule.
In recent years, the incidence of thyroid diseases has increased significantly and ultrasound examination is the first choice for the diagnosis of thyroid diseases. At the same time, the level of medical image analysis based on deep learning has been rapidly improved. Ultrasonic image analysis has made a series of milestone breakthroughs, and deep learning algorithms have shown strong performance in the field of medical image segmentation and classification. This article first elaborates on the application of deep learning algorithms in thyroid ultrasound image segmentation, feature extraction, and classification differentiation. Secondly, it summarizes the algorithms for deep learning processing multimodal ultrasound images. Finally, it points out the problems in thyroid ultrasound image diagnosis at the current stage and looks forward to future development directions. This study can promote the application of deep learning in clinical ultrasound image diagnosis of thyroid, and provide reference for doctors to diagnose thyroid disease.
Objective To investigate the clinical significance of the three iodide transporters in thyroid diseases. Methods Literatures about the Na+/I- symporter (NIS), pendrin and human apical iodide transporter (hAIT) in recent years were reviewed and their expressions in different thyroid diseases were also analyzed. Results NIS proteins express at the basolateral membrane of thyrocytes in normal thyroid tissue, while pendrin and hAIT proteins are limited to the apical membrane of thyrocytes lining in the follicular lumen. In the tissues of thyroid carcinomas, it was found that the NIS proteins expressed in the cytoplasm and their expressions decreased; The mutation of NIS gene may be one of the main causes of congenital hypothyroidism. The expression of prendrin protein may be related to the function of follicles: its expression level increased significantly both in Graves diseases and toxic adenomas, but significantly decreased in differentiated thyroid carcinoma. However, the correlation between the decrease and the degrees of differentiation of carcinoma cell line are still disputable. The expression of hAIT protein does not significantly altered in hyperfunctioning tissues. It only slightly decreased occasionally in hypofunctioning adenomas, but it decreased significantly in thyroid carcinomas. Conclusion The abnormal expressions of the three iodide transporters may be related closely with the type of thyroid diseases. However, their pathogenic mechanisms and the causes of their abnormal expression are still unknown, which need to be studied further.
ObjectiveTo investigate the diagnosis, treatment, classification, and epidemiology of thyroid tuberculosis. MethodsA retrospective study of 5 cases of thyroid tuberculosis and a review of the literatures were analyzed, which related to the clinical characteristics, the gist of the diagnosis and treatment, the causes of misdiagnosis and the methods of operation. ResultsAll of the cases were misdiagnosed before operation. Two cases were diagnosed by the frozen sections during the operations and three cases were diagnosed by postoperative pathology. Subtotal resection or lobectomy and local excision (3 cases) were performed respectively. Debidement and anti-tuberculosis medicine were given locally in 2 unresectable cases. All patients underwent standard chemotherapy for 6－8 months after operations and recovered finally. Four cases were caseous necrosis, 1 case was hyperplasia, all of which were chronic infections thyroid tuberculosis, and no acute thyroid tuberculosis be found. No recurrence was found in the 2－15 years of follow-up. ConclusionsUsually, it is difficult to establish a definite preoperative diagnosis for thyroid tuberculosis. Treatment, such as resection, debridement with local medication or systemic chemotherapy, shall be taken individually according to pathology types, focal features, and comorbidities. For hyperplasia cases, surgical resection shall be the best choice, while, for caseous necrosis cases, sometime difficult to remove, debridement with local medication may be suitable.
ObjectiveTo summarize and analyze the possible association between thyroid diseases and alopecia areata. MethodThe literatures on the relationship between thyroid disease and alopecia areata in recent years were searched and reviewed. ResultsAmong individuals with alopecia areata, the risk of thyroid disease was heightened. They were more susceptible to autoimmune thyroid conditions, often accompanied by thyroid function abnormalities. Moreover, alopecia areata patients face an increased risk of thyroid cancer. However, in patients with thyroid disease, the change of the incidence of alopecia areata was not completely clear. The risk of alopecia areata was increased in patients with autoimmune thyroid disease, and abnormal thyroid function may be one of the potential reasons for the persistence of alopecia areata. ConclusionsAutoimmune thyroid disease and alopecia areata may have a common disease basis. Patients with alopecia areata are at greater risk of autoimmune thyroid disease and thyroid dysfunction. The increased risk of alopecia areata in patients with autoimmune thyroid disease may be related to abnormal thyroid function.
