Objective To summarize the development, clinical application, advantages and disadvantages, and future prospects of parathyroid autofluorescence in recent years. MethodThe literatures related to the research progress of parathyroid autofluorescence in recent years were searched, and launched a specific discussion. Results Autofluorescence of parathyroid gland was still in its infancy at home and abroad. The existing studies had shown that this technique was superior to visual recognition and could reduce the incidence of postoperative complications. Autofluorescence technology had shown some advantages in identifying parathyroid gland during operation, and its mechanism research and related equipment improvement should be focused in the future. ConclusionAutofluorescence technique is of great value in the identification of parathyroid glands in patients undergoing thyroidectomy or parathyroidectomy.
Objective To summarize the research progress on diagnostic criteria of lymph node metastasis in medullary thyroid carcinoma (MTC), and the indication and scope of lateral cervical lymph node dissection (LCLND). Method By searching PubMed and CNKI databases, the related guidelines and literature about the diagnosis and treatment of lateral cervical lymph node metastasis in MTC in recent years were obtained and reviewed. Results The metastatic rate of lateral cervical lymph nodes in MTC patients was high. The indication of LCLND was both consensus and controversy. The LCLND of MTC was also controversial, and the focus of controversy mainly focused on the survival rate, recurrence rate, distant metastasis and postoperative complications of patients receiving prophylactic LCLND. Different imaging methods had their own advantages and disadvantages in diagnosing lymph node metastasis of MTC. Nuclear medicine was effective but expensive. Fine needle puncture was also an effective method for the diagnosis of lymph node metastasis of MTC. At present, calcitonin level, tumor size and lymph node metastasis were still important indicators for evaluating MTC for prophylactic LCLND, but the application of related indications had not been unified. Many scholars recommended comprehensive consideration of various indicators to evaluate whether MTC carried out preventive LCLND. Conclusions The LCLND of MTC needs to be further explored and standardized on the basis of the existing consensus. The focus of prophylactic LCLND should be to improve the survival rate of patients while reducing complications as much as possible.
ObjectiveTo understand the methods of judging the blood supply of parathyroid during thyroidectomy at home and abroad in recent years. MethodThe literature on parathyroid blood supply was collected, the research progress was reviewed, and the advantages and disadvantages of related methods were analyzed. ResultsIn recent years, near-infrared fluorescence, laser speckle contrast imaging and other technologies had been applied. They showed better advantages as compared with naked eye observation. The research on parathyroid blood supply at home and abroad was still in its infancy, and more clinical samples and related equipment optimization were still needed. ConclusionFluorescence imaging technology has a certain auxiliary role in the judgment of intraoperative parathyroid blood supply and can reduce the incidence of hypoparathyroidism to a certain extent.
ObjectiveTo summarize the clinical manifestations, pathogenesis, diagnosis and treatment of multiple endocrine neoplasia type 1 (MEN-1) so as to improve the understanding of MEN-1.MethodThe clinical data of 1 case of MEN-1 with new mutated gene in the Yantai Yuhuangding Hospital of Medical College of Qingdao University (our hospital) were analyzed retrospectively.ResultsThe patient was a 73-year-old woman, who was admitted to our hospital because of “abdominal pain, diarrhea” for 4 d. After discussion by a multidisciplinary team, MRI of pancreatic, adrenal and pituitary, and endoscopy examinations were performed to further identify the cause of diarrhea. Meanwhile, MEN-1 gene was detected in the peripheral blood of the patient and her relatives, and the result showed that the proband and his daughter had a cytosine deletion at c.1401 in exon 10 of MEN-1 gene, which resulted in frame shift mutation of p.e468r fs, it was confirmed as MEN-1. After 5 d of conservative treatment of the disease, the patient’s family requested discharge and the patient died half a month after discharge.ConclusionsMEN-1 is a rare autosomal dominant inheritable disease, with diverse clinical manifestations and easy misdiagnosis. Therefore, it is necessary to be alert to abnormal indicators in the glands associated with MEN-1, so as to achieve early diagnosis and treatment.
