Observation was supplemented with a brief review of literature and discussion. On the basis of this observation and a brief review of literature authors suggested that the potential adverse effects of interferon therapy are overbalanced than its benefits for gynecological patients, therefore any interferon treatment should be recommended with strict indications as well as after screening of conditions and functions of thyroid glands and other interferon target organs to avoid interferon treatment side effects. Practitioners especially gynecologists should inform their patients about pleiotropic interferon effects and its high frequent and wide range side effects before to start such kind of treatment.展开更多

Few ultra-strvctural changes following TSE stimulation could be detected compared withthe control group. Parafollicular cells were detected after being cultured for 96h in the presence of TSH. For the first time, we used scanning electron micro-scope to study the ultrastructural changes of organ cultured thyroid gland.展开更多

The results showed that the level of T4 in rat serum increased and the level of TSH unchanged by the intraperitoneal administration, and the levels of T3, T4 and TSH did not increase by the oral and tail intravenous administration. The evidences mentioned above were in accord with the morphological changes of thyroid follicular epithelial cells andadenohypophysis thyrotroph observed under electronic microscope in a sense.展开更多

Methods: We studied 19 patients diagnosed with cancer in childhood or adolescence who underwent thyroidectomy and supplemental therapy with I-131. We also recruited a control group of healthy subjects with the same demographic parameters. All patients were subjected to a scintigraphy examination of the salivary glands, and were also asked to complete a questionnaire in order to assess their overall quality of life. In addition, a more specific questionnaire for patients with head and neck cancer was also given to all study participants. Results: The quantitative and qualitative analyses of the salivary glands showed functional deficits with greater involvement of the parotid gland for volume, concentration and excretion. The right submandibular gland showed significant changes for volume in the patient group. The questionnaires made it possible to observe significant differences between the patient and control groups for symptoms such as thick saliva, dry mouth and speech problems. Conclusion: In spite of being very effective and widely used, iodine radionuclide therapy is correlated with a lower quality of life in young people.展开更多

We report a 23-year-old man who was emergently hospitalized for paroxysmal syncope and involuntary tremor with normal physical examination except for low heart rate. The patient was characterized by neurological symptoms, mild hypothyroidism, enlarged pituitary gland and extremely elevated thyrotropin, which all were reversed with levothyroxine alone. The case indicated that the pituitary-thyroid dysfunction may play a role in the pathogenesis of Hashimoto’s encephalopathy, hence, evaluation of pituitary gland should be recommended in diagnosis and treatment of Hashimoto’s encephalopathy.展开更多

Early in 1996, she began her neck, accompanied with hoarseness. In June, 2000, when she entered our hospital and accepted a physical examination, we found a 3 cm×2 cm tumor at the lower pole of the thyroid gland. Neck CT showed that the mass was located at the inferiorposterior right part of the thyroid gland with a diffuse boundary. MRI showed that the right thyroid cartilage wall was incomplete. Fine-needle aspiration cytology indicated a suspected papillary tumor.展开更多

We report a case of ЕNB located in inferior nasal concha, combined with thyroid gland carcinoma and gastrointestinal stromal carcinoma in a 77-year-old man. The tumor was resected endonasally. When the final diagnosis of olfactory neuroblastoma was confirmed by histopathologic examination and immunohistochemical staining, the PET/CT examination was performed. The imaging revealed a small focus of a moderately increased cancer activity in the thyroid region. A gastrointestinal stromal carcinoma was detected one year after the resection of the thyroid gland. We discuss the clinical appearance of ENB, staging systems, diagnosis and management. During the endonasal surgery, ENB was removed entirely. Seven days after operation, in order to monitor the postoperative result, PET/CT was performed and a papillary thyroid cancer was detected. One year after the thyroid surgery, gastroendoscopy showed a neoplastic formation in the stomach. In conclusion, we state that when identified as aggressive tumors such as ENB, it is necessary to provide regular examinations in order to detect distant ENB metastases or other neoplastic localisations.展开更多

A lot of researchers studied the possible effect of radiofrequency energy (RFE) emitted from cell phones on the human body. Up to our knowledge no one studied the effect of these waves on the thyroid gland by Ultrasonography (US). Our aim was to investigate the possible effects of EMR arising from cell phones on the thyroid gland using US. A prospective study was done on 180 participants, 110 females and 70 males, ranging in age from 15 to 65. A constructed questionnaire was distributed among them before performing US of the neck. Demographic data along with US findings were collected and statistically analyzed. A total of 46.7% of our participants had abnormal findings of the thyroid gland more in non smart phone users and more in females. The commonest abnormality was multinodular goiter (54%). Expanded researches are still needed to answer the question about the hazards of RFE on human health. All efforts should be made to encourage users of cellular phone to follow mobile device recommendations of manufacturers and avoid its possible hazards as possible.展开更多

文摘BACKGROUND Metastasis to the thyroid gland(TM)from primary breast cancer is uncommon and usually presents as thyroid nodules;however,diffuse goiter without thyroid nodules is the first sign of TM in rare cases.Skip metastases(SMs)to the lymph nodes in breast cancer,defined as discontiguous higher-level metastases in the absence of lower levels of contiguous metastases,have been reported in the contralateral cervical area of the primary tumor site in rare cases.CASE SUMMARY A 49-year-old previously healthy Chinese woman was diagnosed with right lateral invasive ductal carcinoma and underwent neoadjuvant chemotherapy treatment and bilateral mastectomy with axillary lymph node dissection.No malignancy of the left breast or axillary or distant metastases were identified preoperatively.However,enlarged left cervical lymph nodes were detected 36 mo after surgery,and rapidly enlarging thyroid glands without nodules were detected 42 mo after surgery.Fine-needle aspiration cytology was performed on the left cervical lymph nodes and left lobe of the thyroid,which were both revealed to contain metastases from the primary breast cancer.Additionally,the immunostaining profiles changed in the process of metastases.The patient was discharged with the NP(vinorelbine and cisplatin)regimen for subsequent treatment,and stable disease was determined when the curative effect was evaluated.CONCLUSION Diffuse goiter may be the first sign of TM,and enlarged lymph nodes in the contralateral cervical area may be SMs of primary breast cancer.
文摘Blunt trauma to the thyroid gland is a possibly life- threatening condition known for years. However, only few cases have been reported in the English-language literature, so that no consensus has emerged as to its workup or management.
文摘Full thickness burns of 30% TBSA by napalm was inflicted to rats and the pathologi-cal changes of the thyroid were observed with optical and electron microscopy and with peroxi-dase histoehemistry for 15 days postburn.Dynamic changes of the serum level of T<sub>3</sub> and T<sub>4</sub> wereobserved concomitantly.It was found that the postburn pathological changes of the thyroid couldbe distinguished into 3 phases as follows:The phase of injury inhibition.This lasted from the 2nd to the 24th hour postburn and wascharacterized by marked damage of the follicular epithelium.The phase of structural and functional recovery.This lasted from the 3rd to 6th day post-burn and was characterized by abated damage of the thyroid and a tendency to recover.The phase of active function.This lasted from the 10th to the 15th day postburn.The syn-thesizing and releasing organellae of the thyroid were well-restored.The changes of T<sub>4</sub> were parallel to the pathological changes of the thyroid in all the stages,while T<sub>3</sub> level was continously inhibited because of the low serum level of T<sub>4</sub>,the metabolic dis-turbance of T<sub>4</sub> deiodination,and the inhibition of thyroid secretion in the early postburn stage andthe metabolic disturbance of T<sub>4</sub> deiodination in the middle and late postburn stages.In the earlypostburn stage,the inhibition on thyroid peroxidase was an important factor to inhibit the func-tion of the thyroid.
文摘BACKGROUND Secondary malignancies of the thyroid gland are a rare finding in clinical practice.In addition,colorectal metastasis to the thyroid(CMT)is even more infrequently diagnosed.The source of the primary tumor follows demographic and ethnic patterns,which reflects the most prevalent malignancies in the different populations.Colorectal cancer is one of the most common types of cancer worldwide;nevertheless,CMT is infrequently diagnosed.Most of them are identified during the follow-up of gastrointestinal primary malignancies.Due to the improvement of image techniques,oncological treatment,and follow-up,survival and consequent diagnosis of metastatic disease are more frequent.Those facts make this entity a diagnostic and therapeutic challenge,due to the lack of information and the difficulties performing clinical trials and research.CASE SUMMARY Here,we present a case report of a patient diagnosed with CMT of adenocarcinoma of the rectum evidenced during follow-up,4 years after neoadjuvant chemoradiotherapy,who had subsequent curative surgical treatment of the primary tumor and inter-current lung bilateral metastases.CONCLUSION Thyroid metastases of extra-thyroid origin are an uncommon finding,even rarer in cases of CMT.The diagnostic process,as well as survival of oncologic patients is improving,and consequently the number of metastases to the thyroid gland is increasing.
文摘A culture technique had been developed by which the normal mor-phological integrity of the porcine thyroid tissue was well preserved. Few ultra-strvctural changes following TSE stimulation could be detected compared withthe control group. Parafollicular cells were detected after being cultured for 96h in the presence of TSH. For the first time, we used scanning electron micro-scope to study the ultrastructural changes of organ cultured thyroid gland.
文摘The levels of thyroxine (T3, T4) and thyroid stimulating hormone (TSH) in rat serum were measured by radioimmunoassay, and also ultrastructure of the thyroid gland and adenohypophyseal cell were examined by transmission electronic microscopy (TEM) after low concentration (0. 05 mg/kg) of samarium chloride (SmCl3) administration by intraperitoneal, oral and tail intravenous routes. The results showed that the level of T4 in rat serum increased and the level of TSH unchanged by the intraperitoneal administration, and the levels of T3, T4 and TSH did not increase by the oral and tail intravenous administration. The evidences mentioned above were in accord with the morphological changes of thyroid follicular epithelial cells andadenohypophysis thyrotroph observed under electronic microscope in a sense.
文摘Goal: To evaluate the impact of iodine-131 therapy received during childhood and adolescence and correlate it with the quality of life in these patients. Methods: We studied 19 patients diagnosed with cancer in childhood or adolescence who underwent thyroidectomy and supplemental therapy with I-131. We also recruited a control group of healthy subjects with the same demographic parameters. All patients were subjected to a scintigraphy examination of the salivary glands, and were also asked to complete a questionnaire in order to assess their overall quality of life. In addition, a more specific questionnaire for patients with head and neck cancer was also given to all study participants. Results: The quantitative and qualitative analyses of the salivary glands showed functional deficits with greater involvement of the parotid gland for volume, concentration and excretion. The right submandibular gland showed significant changes for volume in the patient group. The questionnaires made it possible to observe significant differences between the patient and control groups for symptoms such as thick saliva, dry mouth and speech problems. Conclusion: In spite of being very effective and widely used, iodine radionuclide therapy is correlated with a lower quality of life in young people.
文摘The pathogenesis of Hashimoto’s encephalopathy has not been clearly elucidated and involvement of autoimmune damage has been proposed. We report a 23-year-old man who was emergently hospitalized for paroxysmal syncope and involuntary tremor with normal physical examination except for low heart rate. The patient was characterized by neurological symptoms, mild hypothyroidism, enlarged pituitary gland and extremely elevated thyrotropin, which all were reversed with levothyroxine alone. The case indicated that the pituitary-thyroid dysfunction may play a role in the pathogenesis of Hashimoto’s encephalopathy, hence, evaluation of pituitary gland should be recommended in diagnosis and treatment of Hashimoto’s encephalopathy.
文摘BACKGROUND Esophageal cancer is one of the most common causes of cancer-related death.Some patients with esophageal cancer have distant metastases at the time of diagnosis,but metastasis to the thyroid gland(MTG)and multifocal thyroid lesions alone are extremely rare.CASE SUMMARY In this case report,we present a case of a 69-year-old male with esophageal MTG.The patient visited our hospital for a routine body check-up,which revealed multifocal nodules in his thyroid lobes and enlarged cervical lymph nodes.A fine needle aspiration biopsy showed malignancies in both thyroid lesions and lymph nodes.The patient was initially diagnosed with primary bilateral thyroid cancer that spread to his lymph nodes,and a total thyroidectomy was performed.The histology showed MTG and therefore,a diagnostic work-up was implemented to determine the primary tumor.A fluorine-18-deoxyglucose positron emission tomography scan showed that the lower part of the esophagus and the lymph nodes in the neck,chest,and abdomen were involved.An esophagogastroscopy and corresponding pathology revealed distal esophageal squamous cell carcinoma.The esophageal MTG diagnosis was confirmed with pathological immunohistochemistry.CONCLUSION This case report highlights the difficulty in diagnosing esophageal MTG.Patients may have no malignancy history and be asymptomatic.Further diagnostic procedures are necessary after MTG is confirmed by cytology or histology,and the final diagnosis should be made according to the identification of the primary malignancy combined with pathological immunohistochemistry findings.
文摘The patient was a female, 65 years to feel intermittent discomfort in old. Early in 1996, she began her neck, accompanied with hoarseness. In June, 2000, when she entered our hospital and accepted a physical examination, we found a 3 cm×2 cm tumor at the lower pole of the thyroid gland. Neck CT showed that the mass was located at the inferiorposterior right part of the thyroid gland with a diffuse boundary. MRI showed that the right thyroid cartilage wall was incomplete. Fine-needle aspiration cytology indicated a suspected papillary tumor.
文摘Given the high incidence of cervical lymph node metastasis in differentiated thyroid cancer （DTC） and the rapidly increased importance of neck dissection in DTC, the journal of Gland Surgery is launching a special issue on ＂Neck Dissection in Differentiated Thyroid Carcinoma＂ in November Issue of 2013, inviting Dr. Xinying Li from Xiangya Hospital, China, as the guest editor.
文摘Olfactory neuroblastoma (esthesioneuroblastoma, ЕNB) is a rare tumor arising from the olfactory neuroepithelium. We report a case of ЕNB located in inferior nasal concha, combined with thyroid gland carcinoma and gastrointestinal stromal carcinoma in a 77-year-old man. The tumor was resected endonasally. When the final diagnosis of olfactory neuroblastoma was confirmed by histopathologic examination and immunohistochemical staining, the PET/CT examination was performed. The imaging revealed a small focus of a moderately increased cancer activity in the thyroid region. A gastrointestinal stromal carcinoma was detected one year after the resection of the thyroid gland. We discuss the clinical appearance of ENB, staging systems, diagnosis and management. During the endonasal surgery, ENB was removed entirely. Seven days after operation, in order to monitor the postoperative result, PET/CT was performed and a papillary thyroid cancer was detected. One year after the thyroid surgery, gastroendoscopy showed a neoplastic formation in the stomach. In conclusion, we state that when identified as aggressive tumors such as ENB, it is necessary to provide regular examinations in order to detect distant ENB metastases or other neoplastic localisations.
文摘In recent years, widespread use of mobile phones has led to a public debate about possible harmful effects on human health. A lot of researchers studied the possible effect of radiofrequency energy (RFE) emitted from cell phones on the human body. Up to our knowledge no one studied the effect of these waves on the thyroid gland by Ultrasonography (US). Our aim was to investigate the possible effects of EMR arising from cell phones on the thyroid gland using US. A prospective study was done on 180 participants, 110 females and 70 males, ranging in age from 15 to 65. A constructed questionnaire was distributed among them before performing US of the neck. Demographic data along with US findings were collected and statistically analyzed. A total of 46.7% of our participants had abnormal findings of the thyroid gland more in non smart phone users and more in females. The commonest abnormality was multinodular goiter (54%). Expanded researches are still needed to answer the question about the hazards of RFE on human health. All efforts should be made to encourage users of cellular phone to follow mobile device recommendations of manufacturers and avoid its possible hazards as possible.
