    This chapter reviews the correlation between thyroid disease, other than cancer, and radiation in the literature. Radiation-induced thyroid disturbance is discussed in the context of external and internal irradiation. External irradiation of 10 to 40 Gy may lower thyroid function several months or years later. Oral administration of I-131 is widely given to patients with Basedow's disease; it may also lower thyroid function with increasing radiation doses. When giving 70 Gy or more of I-131, hypothyroidism has been reported to occur in 20-30% and at least 10%. Thyroiditis induced with internal I-131 irradiation has also been reported, but no data is available concerning external irradiation-induced thyroiditis. The incidence of nodular goiter was found to be several ten times higher with external irradiation than internal irradiation. Thyroid disturbance is correlated with A-bomb survivors. A-bomb radiation can be divided into early radiation within one minute after A-bombing and the subsequent residual radiation. Nodular goiter was significantly more frequent in the exposed group than the non-exposed group; it increased with increasing radiation doses and younger age (20 years or less) at the time of exposure. The incidence of decrease in thyroid function was higher with increasing radiation doses. However, in the case of Nagasaki, the incidence of hypothyroidism was significantly higher in the low-dose exposed group, especially A-bomb survivors aged 10-39 at the time of exposure and women.

    Full Text Available BACKGROUND Thyroid diseases and diabetes mellitus are the most common endocrine diseases during pregnancy. Internal Medicine doctors could be involved in the management of pregnant women affected by thyroid diseases, in particular if an Endocrine Unit lacks in the hospital; it is mandatory that they have the skills to cope with these diseases. METHODS In this work authors describe the most common thyroid abnormalities that can occur during pregnancy: hypothyroidism (clinical and subclinical, hyperthyroidism (clinical and sub-clinical, autoimmune thyroiditis (in particular the so called post-partum thyroiditis, nodular diseases and cancer. They discuss moreover the peculiar pathophysiologic mechanisms by which these diseases appear, the diagnostic tools and the therapies, according to their own experience and the more recent international guidelines. RESULTS AND CONCLUSIONS It is important to evaluate thyroid function tests before and during pregnancy, at 16th and 28th gestational week; it is mandatory to cure also the “sub-clinical” hypothyroidism during pregnancy, when TSH level are higher than 5 μIU/mL; the optimal dose of levo-thyroxine during pregnancy is, average, 30-50% higher than that used before pregnancy; it is not correct to treat mild or sub-clinical hyperthyroidism; propylthyouracil is the best drug to treat hyperthyroidism during pregnancy; the post-partum thyroiditis is generally transient, so that a careful monitoring of thyroid function is advisable, in particular after 9-12 months of therapy; thyroid cancer, if discovered during pregnancy, generally has no negative effects on the outcome of the pregnancy; it would be better to treat surgically thyroid cancer during the last trimester of the pregnancy.

    Subclinical thyroids disease (STD) is recently defined term in clinical thyroidology, which includes mainly functional disorders. Basic diagnostic signs are: normal values of thyroid hormones (fT4, fT3) and elevated TSH level (subclinical hypothyroidism) or suppresed TSH level (subclinical hyperthyroidism). In a category of STD may be included subclinical autoimunne thyroiditis (elevated level of thyroid antigens antibodies and/or hypoechogenity in sonographic screen, increased volume of the thyroid without clinical symptoms and/or autoimminity) and microscopic lesions of papillary thyroid carcinoma. Subclinical hypothyroidism may be dangerous for tendency to development of manifest hypothyroidism and for risk of disorders of lipid profile and development of atherosclerosis and its organ complication (esp. myocardial infarction). Subclinical hyperthyroidism is a risk factor of cardiac arythmias and probably can increase a risk of cardiovascular mortality) as well for osteoporosis (esp. in peri- and post-climacteric women), and last but not least for degenerative diseases of brain (?). Indication of treatment of STD is a matter of controversies. Recomendations of experts, varied from "no therapy, monitoring only" to "treat always". Treatment of risk groups (esp. pregnant women) is probably nowadays a most rationale recommendations since results of sofisticated prospective studies will be available.

    2010-01-01

    Both Graves' disease and chronic thyroiditis (Hashimoto's thyroiditis) are autoimmune diseases of thyroid gland. Graves' disease is caused by stimulation of TSH receptor located on the thyroid gland by an antibody, which is known as TSH receptor antibody (TRAb). Furthermore, this may lead to hyperplasia and hyperfunction of the thyroid gland. On the contrary, the cause of Hashimoto's thyroiditis is thought due to a TSH stimulation-blocking antibody (TSBAb) which blocks the action of TSH hormone and subsequently brings damage and atrophy to thyroid gland. Approximately 15-20% of patients with Graves' disease had been reported to have spontaneous hypothyroidism resulting from the chronic thyroiditis (Hashimoto's disease). Pathogenesis for chronic thyroiditis following anti-thyroid drug treatment in patients with Graves' disease remains unclear. It has been estimated that chronic thyroiditis or Hashimoto's disease, which occurs following the Graves' disease episode is due to extended immune response in Graves' disease. It includes the immune response to endogenous thyroid antigens, i.e. thyroid peroxidase and thyroglobulin, which may enhance lymphocyte infiltration and finally causes Hashimoto's thyroiditis. We report four cases of chronic thyroiditis (Hashimoto's disease) in patients who have been previously diagnosed with Graves' hyperthyroidism. In three cases, Hashimoto's thyroiditis occurs in 7 to 25 years after the treatment of Grave's disease; while the other case has it only after few months of Grave's disease treatment. The diagnosis of Hashimoto's disease (chronic thyroiditis) was based on clinical manifestation, high TSHs level, positive thyroid peroxidase antibody and thyroglobulin antibody, and supported by positive results of fine needle aspiration biopsy. Moreover, the result of histopathological test has also confirmed the diagnosis in two cases. All cases have been successfully treated by levothyroxine treatment.

  16. Graves' disease following subacute thyroiditis.

    Nakano, Yoshishige; Kurihara, Hideo; Sasaki, Jun

    2011-12-01

    Subacute thyroiditis is a painful, inflammatory disease frequently accompanied with fever. It is suspected to be a viral infectious disease, while Graves' disease is an autoimmune disease. Thus, there appears to be no etiological relationship between the two diseases. A total of 25,267 thyroid disease patients made their first visits to our thyroid clinic during a period of 24 years between 1985 and 2008. Among them, subacute thyroiditis and Graves' disease accounted for 918 patients (3.6%) and 4,617 patients (18.2%), respectively. We have encountered 7 patients (one male and six female) with subacute thyroiditis followed by Graves' disease in this period (0.15% of the 4,617 patients with Graves' disease and 0.76% of the 918 patients with subacute thyroiditis). The age ranges were 40~66 years (mean 48.7 years) at the onset of subacute thyroiditis. The intervals between the onsets of subacute thyroiditis and Graves' disease were 1~8 months (mean 4.7 months). Because Graves' disease was preceded by subacute thyroiditis, the signs and symptoms of both diseases were evident together in the intervening period. The diagnosis of Graves' disease in those patients is always difficult because of atypical signs and symptoms and an unclear onset time. The causes of the Graves'disease that followed subacute thyroiditis are still unknown. However, the inflammatory nature of subacute thyroiditis may lead to the activation of the autoimmune response in susceptible subjects, resulting in the onset of Graves' disease. Graves' disease should be suspected when a high blood level of thyroid hormone persists after subacute thyroiditis.

    Environmental factors are determinant for the appearance of autoimmune thyroid diseases (AITD) in susceptible subjects. Increased iodine intake, selenium, and vitamin D deficiency, exposure to radiation, from nuclear fallout or due to medical radiation, are environmental factors increasing AITD. Cigarette smoking is associated with Graves' disease and Graves' ophthalmopathy, while it decreases the risk of hypothyroidism and thyroid autoimmunity. Viral infections are important environmental factors in the pathogenesis of AITD, too, particularly human parvovirus B19 (EVB19) and hepatitis C virus. Among the many chemical contaminants, halogenated organochlorines and pesticides variably disrupt thyroid function. Polychlorinated biphenyls and their metabolites and polybrominated diethyl ethers bind to thyroid transport proteins, such as transthyretin, displace thyroxine, and disrupt thyroid function. Among drugs, interferon- and iodine-containing drugs have been associated with AITD. Moreover intestinal dysbiosis causes autoimmune thyroiditis. To reduce the risk to populations and also in each patient, it is necessary to comprehend the association between environmental agents and thyroid dysfunction.

    Objective: To evaluate the prevalence of subclinical thyroid disease (SCTD) in local population visiting a hospital laboratory for thyroid function tests. Design: It was a hospital - based study carried in consecutive patients who reported for thyroid function tests in the hospital laboratory. Place and duration of study: The study was conducted in combined military Hospital, Quetta during June 1999 to September 2000. Subject and methods: Serum samples of 917 patients living in Quetta and its surrounding were analysed for thyroid stimulating hormone (TSH) free thyroxin (FT4), and total tri-iodothyronine (T3) concentration using chemiluminescence technique on hormone auto analyser (LIA-Mat - Sangtech Germany). Results: Out of 917 patients, 287 (23%) were found to be having SCTD while overt thyroid disease was found in 288 (31%) patients. Prevalence of sub-clinical hypothyroidism (SCO) and sub-clinical hyperthyroidism (sce) was found to be almost equal with a profound female preponderance in both the groups. SCO was more common in children (<12 years of age). Conclusion: Almost every fourth patient reporting for thyroid function tests was diagnosed as having SCTD - a disease entity that is still not well known and that poses diagnostic and management problems for the pathologists and clinicians.

    Radioactive iodine is released at every atomic-bomb testings and nuclear plants accidents and radioactive iodine is taken up by thyroid glands (internal radiation). In addition to the internal radiation, radioactive fallout causes the external radiation and thyroid glands are known to be sensitive to the external radiation. Furthermore, patients with radiation-induced thyroid disease can survive for a long time regardless of the treatment. The survey of thyroid diseases, therefore, is very sensitive and reliable ways to investigate the effects of radiation caused by atomic bomb explosion, testing and various types of nuclear plants' accidents. Our group from Nagasaki University was asked to investigate the thyroid diseases and jointed to the Sasakawa Project. In order to investigate the effects of radiation on thyroid disease, it is essential 1) to make a correct diagnosis in each subject, 2) to calculate a correct radiation dose in each subject and finally, 3) to find out the correlation between the radiation dose and thyroid diseases including age-, sex- and area-matched controls. We have established 5 centers (1 in Russia, 2 in Belarus, 2 in Ukraine) and supplied the most valuable ultrasonography instruments, commercial kits for the determination of serum free T 4 and TSH level and for the autoantibodies, instrument for urinary iodine measurements, syringers, tubes, refrigerators, etc. We visit each center often and asked people at centers to come to Japan for training. Protocol of investigation is essentially the same as that in Nagasaki, and we are planning to investigate more than 50,000 children within 5 years. We are hoping to show a definite conclusion in the near future. Recent articles are also discussed. (author)

    Okamoto, Kyoko; Imanishi, Yoshimasa; Nakaji, Shunsuke; Shinagawa, Toshihito

    2007-01-01

    Imanishi et al. have previously reported that the changes in CT values reveal not only the change in iodine concentration in thyroid follicles, but also represent secondary changes in follicular content and follicular cells and/or interstitial structures. Thus, we performed thyroid CT without contrast material in 138 controls, 417 cases with diffuse thyroid diseases, and 279 cases with thyroid nodules, and evaluated the CT images based on the relation between the change in CT values and pathological changes. In 89% of the controls and 43% of patients with diffuse thyroid diseases, the thyroid CT revealed diffuse high density. In contrast, the 94% of thyroids that demonstrated diffuse low density were from patients with diffuse thyroid diseases. Eighty-four percent of malignant nodules and 64% of benign nodules had inhomogeneous densities, and only 26% of benign thyroid nodules had homogeneous density. However, 71% of nodules that showed high and low densities with regular and clear borders, and 82% of nodules that showed papillary proliferation in a cyst pattern were benign. Although only 58% of nodules with calcification were malignant, 66% of nodules with calcification in the central portion, and 86% of nodules with calcification of a disseminated and convergent pattern in distribution were malignant. Sixty-two percent of thyroids that surrounded nodules had chronic thyroiditis, hypoplasia and/or adenomatous goiter. Thus, unclear borders between a nodule and the surrounding thyroid tissue did not increase the possibility of malignancy. However, the unclear and/or lobulated border between a nodule and extra thyroid tissue increased the possibility of malignancy. We concluded that thyroid CT without contrast material is useful for the diagnosis of thyroid diseases. (author)

    This book is based on the authors' extensive practical experience in the use of modern ultrasound, and other radiological methods, in the diagnosis of thyroid diseases. The authors have analyzed more than 100,000 ultrasound examinations performed between 1995 and 2008 in patients with thyroid and parathyroid disease, as well as many thousands of diagnostic and therapeutic ultrasound-guided minimally invasive procedures. The opening chapters include discussion of current ultrasound techniques, pitfalls, and the specifics of ultrasound examination of the thyroid in children. Detailed attention is then devoted to findings in the normal thyroid and in the presence of diffuse and focal changes. Further chapters focus on such topics as ultrasound examination after thyroid surgery and ultrasound diagnosis of parathyroid disease, recurrent goiter, and neck masses. Ultrasound-guided minimally invasive techniques, such as fine-needle aspiration biopsy, percutaneous laser ablation, and ethanol and glucocorticoid injections, are considered in depth. This up-to-date and richly illustrated book will interest and assist specialists in ultrasound diagnostics, radiologists, endocrinologists, and neck surgeons. (orig.)

    Allelein, S; Feldkamp, J; Schott, M

    2017-01-01

    Autoimmune diseases of the thyroid gland are considered to be the most frequent cause of thyroid gland disorders. Autoimmune thyroid diseases consist of two subgroups: autoimmune thyroiditis (AIT) and Graves' disease. The AIT is the most common human autoimmune disease. Infiltration of the thyroid gland with cytotoxic T‑cells can lead to an initial thyrotoxicosis und during the course to hypothyroidism due to destruction of the thyroid gland. Substitution with Levothyroxine is indicated for manifest hypothyroidism and subclinical hypothyroidism with increased thyroid antibodies with the intention of normalizing the serum thyroid stimulating hormone (TSH). Graves' disease is characterized by the appearance of stimulating TSH receptor antibodies leading to hyperthyroidism. Endocrine ophthalmopathy may also occur. Ablative therapy with radioiodine therapy or thyroidectomy is administered to patients with Graves' disease without remission after at least 1 year of antithyroid drug therapy.

    This report describes the preliminary results of an evaluation conducted in support of the Hanford Environmental Dose Reconstruction (HEDR) Project. The primary objective of the HEDR Project is to estimate the radiation doses that populations could have received from nuclear operations at the Hanford Site since 1944. A secondary objective is to make information that HEDR staff members used in estimate radiation doses available to the public. The objectives of this report to make available thyroid measurement data from Hanford workers for the year 1944 through 1946, and to investigate the suitability of those data for use in the HEDR dose estimation process. An important part of this investigation was to provide a description of the uncertainty associated with the data. Lack of documentation on thyroid measurements from this period required that assumptions be made to perform data evaluations. These assumptions introduce uncertainty into the evaluations that could be significant. It is important to recognize the nature of these assumptions, the inherent uncertainty, and the propagation of this uncertainty, and the propagation of this uncertainty through data evaluations to any conclusions that can be made by using the data. 15 refs., 1 fig., 5 tabs.

  14. The Study on the Thyroid Disease

    Several recent advances in our knowledge of thyroid physiology have broad application to the diagnosis and management of thyroid disorders. For in the thyroid, more than other end-ocrine organs, pathophysiology can be translated directly into the diagnosis and management of thyroid disease. Graves' disease is a syndrome including goiter with hyperthyroidism, exophthalmos and dermatopathy. The pathogenesis of Graves' disease is not yet clearly identified, but various autoantibodies to the thyroid gland and immunapathalogic studied indicate that autoimmune processes are involved in the pathogenesis of the disease. The diagnosis and management of Graves' disease are largely dependent on radionuclide technique as radioimmunoassay, radioactive iodine therapy and so on. Several laboratory tests are also developed to determine the remission of this disease including TRH stimulation test, T 3 , suppression test and detection of thyroid stimulating immunoglobulins. Autoimmune thyroiditis is almost certainly a primary immunologic disease and the incidence tends to increase recently, mainly due to the application of biopsy technique is thyroid diseases. Thyroid nodules have been a great challenge to physicians because of the possibility of malignancy. But recently, cytologic examination of thyroid aspirate provides a very simple and also reliable diagnostic method in patients with thyroid nodules. In 163 patients with thyroid nodules, only 19.3% was revealed to be malignant. Therefore cytologic examination of thyroid aspirate and thyroid biopsy should be included in the diagnosis of nodular patients prior to surgical intervention. In this paper, a comprehensive review is presented on the pathogenesis, clinical features, laboratory findings and therapeutic modalities of various thyroid diseases on the basis of over 80 researches performed during the past 20 years at radioisotope clinic, Seoul National University Hospital.

    Co-existence of thyroid nodules with Graves' disease has been reported in various studies. 10-15% of such nodules harbor thyroid cancer with papillary thyroid cancer being the commonest. Medullary thyroid cancer (MTC) in nodules associated with Graves' disease is rare. On literature survey, we came across 11 such cases reported so far. We report a 62-year-old female with Graves' disease who also had a thyroid nodule that on fine-needle aspiration cytology and the subsequent postthyroidectomy histopathological examination was reported to be MTC.

    The risk of chronic obstructive pulmonary disease (COPD), as well as thyroid diseases increases with age. COPD is a common systemic disease associated with chronic inflammation. Many endocrinological disorders, including thyroid gland diseases are related to systemic inflammation. Epidemiological studies suggest that patients with COPD are at higher risk of thyroid disorders. These associations are not well-studied and thyroid gland diseases are not included on the broadly acknowledged list of COPD comorbidities. They may seriously handicap quality of life of COPD patients. Unfortunately, the diagnosis may be difficult, as many signs are masked by the symptoms of the index disease. The comprehension of the correlation between thyroid gland disorders and COPD may contribute to better care of patients. In this review, we attempt to revise available literature describing existing links between COPD and thyroid diseases.

    Exposure of the thyroid gland to ionizing radiation has been associated with a variety of abnormalities. Among these are tardive hypothyroidism and an increased risk of developing thyroid nodules and cancer. Although acute thyroiditis has been known to complicate radioactive iodine 131 therapy, it has rarely been associated with external beam irradiation. Thyrotoxic painless thyroiditis developed in two patients after mantle-field irradiation for Hodgkin's disease

    Various new approaches have been recently investigated in diagnosis of thyroid diseases with the progress of nuclear medicine. sup(99m)TcO 4 - has become a routinely used radiopharmaceutical in thyroid scan. sup(99m)TcO 4 - thyroid uptake was evaluated by using thyroid-t-high ratio. 123 I thyroid scan is more valuable than 131 I scan because of its short half time and low radiation exposure. We use 123 I particulary in functional analysis of thyroid hot nodule. 201 Tl scans were performed in patients with cold nodule. All thyroid cancer patients showed 201 Tl positive accumulation in thyroid nodule. However, even in benign diseases 201 Tl was accumulated. 201 Tl scan will be most effectively used in detecting the metastatic lesions from thyroid cancer. Serum rT 3 concentration in various diseases was evaluated by RIA method. Serum TBG concentration in various diseases was evaluated by RIA method and T 4 /TBG ratio was evaluated. Serum anti-thyroglobulin antibody titer in thyroid diseases was evaluated by RIA method. It was more objective than widely used tanned red cell hemagglutinin method. (author)

    Thyroid hormones, specifically triiodothyronine (T3), have significant effects on the heart and cardiovascular system. Hypothyroidism, hyperthyroidism, subclinical thyroid disease, and low T3 syndrome each cause cardiac and cardiovascular abnormalities through both genomic and nongenomic effects on cardiac myocytes and vascular smooth muscle cells. In compromised health, such as occurs in heart disease, alterations in thyroid hormone metabolism may further impair cardiac and cardiovascular function. Diagnosis and treatment of cardiac disease may benefit from including analysis of thyroid hormone status, including serum total T3 levels. Copyright © 2014 Elsevier Inc. All rights reserved.

    Some technical aspects of the current and less current tests for thyroid function evaluation and for immunological and cancerous thyroid diseases, were reviewed. This large review was done to confirm that at present, nearly all the parameters playing a role in thyroid disease are measured by RIA technique with an acceptable precision and specificity. It is now possible to study a particular problem of thyroid with a particular assay. The review was illustrated by a certain number of precision profile which are, in our opinion, one of the most important informations to have before adopting a technique. It allows to appreciate what can be obtained -and cannot be obtained- as a reliable response

    Thyroid eye disease (TED) is the most frequent extrathyroidal manifestation of Graves' disease. In most instances it is mild and non-progressive, but in 3%-5% of cases it is severe. Non-severe TED requires only supportive measures, such as eye ointments, sunglasses and prisms. By contrast, severe TED requires aggressive treatment, either medical (high-dose glucocorticoids, orbital radiotherapy) or surgical (orbital decompression). The choice of treatment relies on the assessment of both TED severity and activity. Removal of controllable risk factors, especially cigarette smoking, is important to improve the course and the therapeutic outcome. A coordinated approach to the treatment of hyperthyroidism and TED is also required. Novel promising treatments, to be verified in large series of patients, include somatostatin analogues and cytokine antagonists. (orig.)

    Graves' disease and Hashimoto's thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves' disease from Hashimoto's thyroiditis. This study included 149 patients divided into three groups, patients with Graves' disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto's thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves' was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto's group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves' group with 100% and 17.6% specificity and sensitivity, respectively. Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves' disease or Hashimoto's thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed.

    The biology of thyroid cancer represents a spectrum of behavior ranging from well-differentiated lesions with an excellent prognosis to anaplastic carcinoma, which is almost fatal. For this reason, it is important that clinicians have methods at their disposal to asses the characteristics of patient's thyroid malignancy. In this work we discuss the behavior of differentiated thyroid cancer in associated diseases of thyroid as: Graves' disease, chronic lymphocytic thyroiditis--Hashimoto and nodular goiter. This is retrospectively reviewing of 50 patients treated for differentiated thyroid carcinoma at Department of surgery, Clinical Centre of Montenegro in Podgorica from 1998 until 2003. We evaluated occurrence, as well as the role of this diseases in patients with thyroid cancer. We found a more favorable course of thyroid cancer in the presence of chronic lymphocytic thyroiditis and nodular goiter, a contrary Graves' disease. In associated diseases of thyroid, a significantly greater proportion of patients with thyroid cancer, have modular goiter.

    Studies have showed that lead was associated with human health. However, the effects of lead on thyroid functions are inconsistent, and studies based on Chinese population are fragmentary. To evaluate the correlation between lead and thyroid functions of Chinese with different thyroid diseases, we conducted a hospital-based study. Ninety-six papillary thyroid carcinoma (PTC), 10 nodular goiter (NG), and 7 thyroid adenoma (TA) patients were recruited from the First Affiliated Hospital of Wenzhou Medical University, China. Serum triiodothyronine (T3), free triiodothyronine (FT3), free thyroxin (FT4), and thyroid stimulating hormone (TSH) were evaluated with chemiluminescent microparticle immunoassay. Serum lead was assessed with ICP-MASS. Partial correlation was used to explore the correlations of serum lead and thyroid diseases. Compared to PTC, the level of lead was significantly higher in TA, and lower in NG (p lead was negatively correlated with TSH (r s  =  - 0.27, p lead at quartile4 (r s  = 0.61, p lead and FT3 or FT4 in any group. The results suggested that lead might have different etiological roles in these three thyroid diseases.

    Full Text Available Thyroid hormones play a very important role regulating metabolism, development, protein synthesis, and influencing other hormone functions. The two main hormones produced by the thyroid are triiodothyronine (T3 and thyroxine (T4. These hormones can also have significant impact on kidney disease so it is important to consider the physiological association of thyroid dysfunction in relation to chronic kidney disease (CKD. CKD has been known to affect the pituitary-thyroid axis and the peripheral metabolism of thyroid hormones. Low T3 levels are the most common laboratory finding followed by subclinical hypothyroidism in CKD patients. Hyperthyroidism is usually not associated with CKD but has been known to accelerate it. One of the most important links between thyroid disorders and CKD is uremia. Patients who are appropriately treated for thyroid disease have a less chance of developing renal dysfunction. Clinicians need to be very careful in treating patients with low T3 levels who also have an elevation in TSH, as this can lead to a negative nitrogen balance. Thus, clinicians should be well educated on the role of thyroid hormones in relation to CKD so that proper treatment can be delivered to the patient.

    Radioiodine treatment for thyroid disease has been given for half a decade in Sweden. The most common indication for treatment is hyperthyroidism, when iodine uptake is high. The situation in which radioiodine treatment is used in thyroid cancer is less favourable and measures therefore have to be taken to optimize the treatment. Treatment should be performed early in the course of the disease to achieve the highest possible differentiation. Before treatment the iodine and goitrogen intake should be kept low. Stimulation of the thyrocytes by thyroid-stimulating hormone (TSH) should be high. It is conventionally achieved by thyroid hormone withdrawal rendering the patient hypothyroid, or by the recently available recombinant human TSH (rhTSH) which can be recommended for ablation of the thyroid remnant after thyroidectomy and for treatment of metastases in fragile patients unable to undergo hypothyroidism. Finally, stunning - the negative effect of a prior test dose from radioactive iodine - should be avoided.

    Thyroid disorders are common in the general population and in hospitalized patients. Thyroid disease may present first with neurological complications or else may occur concurrently in patients suffering other neurological disorders, particularly those with an autoimmune etiology. For this reason neurologists will commonly encounter patients with thyroid disease. This chapter provides an overview of the neurological complications and associations of disorders of the thyroid gland. Particular emphasis is placed on conditions such as thyrotoxic periodic paralysis and myxedema coma in which the underlying thyroid disorder may be occult leading to a first, often emergency, presentation to a neurologist. Information about clinical features, diagnosis, pathogenesis, therapy, and prognosis is provided. Emphasis is placed on those aspects most likely to be relevant to the practicing neurologist and the interested reader is directed to references to good, recent review articles for further information. © 2014 Elsevier B.V.

    Early histological changes in the thyroid gland were examined in 30 patients with juvenile thyrotoxicosis, by means of needle biopsy. Based on the degree of lymphocytic infiltration and degenerative changes in follicular epithelium, results were classified into four groups. A: hyperplastic changes without cellular infiltration (6 patients, 20%); B: hyperplastic changes with areas of focal thyroiditis less than 30% of specimen (10 patients, 33%); C: those with 30 to 60% areas ot thyroiditis (10 patients, 33%); D: almost diffuse thyroiditis (4 patients, 13%). Moderate to severe lymphocytic thyroiditis was frequently present in the early stage of hyperplastic thyroid glands. The clinical significance of the 4 histological groups was evaluated. Neither clinical signs nor routine laboratory tests could differentiate these groups except group D, in which thyrotoxic signs were mild and transient. However, serum antithyroid antibodies tended to increase in accordance with severity of thyroiditis. The rate of remission was high in groups C and D, whereas relapse was frequent in group A. These results suggest that Grave's disease and chronic lymphocytic thyroiditis are closely related in the early stage of thyrotoxicosis in children, and that the clinical course may be considerably altered by the degree of associated thyroiditis.

    Full Text Available We have reviewed scientific literature about the association of systemic sclerosis (SSc and thyroid disorders. A high incidence, and prevalence, of new cases of autoimmune thyroiditis (AT and/or hypothyroidism have been shown in sclerodermic patients (overall in the female gender. An association among a Th1 immune-predominance, low vitamin D levels, and AT have been also shown in SSc patients. Cases of Graves’ disease (GD have been described in SSc patients, too, according with the higher prevalence of thyroid autoimmunity. It has been also shown a higher prevalence of papillary thyroid cancer (PTC, in association with AT, in SSc patients. However, in order to confirm results about GD and thyroid cancer, studies in larger number of patients with SSc are needed. During the follow-up of SSc patients it would be appropriate to monitor carefully their thyroid status. The abovementioned data strongly suggest a periodic thyroid function follow-up in female SSc patients [showing a borderline high (although in the normal range thyroid-stimulating hormone level, antithyroid peroxidase antibody positivity, and a small thyroid with a hypoechoic pattern], and, when necessary, appropriate treatments. In conclusion, most of the studies show an association among SSc, AT, and hypothyroidism, such as an increased prevalence of TC overall in SSc patients with AT. Only few cases of GD have been also described in SSc.

    Patients with Graves' disease were studied for two years during and after a twelve-month course of treatment. Disease activity was determined by repeated measurements of thyroidal uptake of [ 9 -9μTc]pertechnetate during tri-iodothyronine administration. These in-vivo measurements of thyroid stimulation were compared with the results of in-vitro assays of Graves, immunoglobulin (TSH binding inhibitory activity - TBIA). There was no correlation between the thyroid uptake and TBIA on diagnosis. Pertechnetate uptake and TBIA both declined during the twelve months of antithyroid therapy. TBIA was detectable in sera from 19 of the 27 patients at diagnosis; in 11 of these 19 patients there was a good correlation (p<0.05) throughout the course of their disease between the laboratory assay of the Graves, immunoglobulin and the thyroid uptake. Probability of recurrence can be assessed but sustained remission of Graves' disease after treatment cannot be predicted from either measurement alone or in combination

    Full Text Available The year following parturition is a critical time for the de novo appearance or exacerbation of autoimmune diseases, including autoimmune thyroid disease. The vast majority of postpartum thyroid disease consists of postpartum thyroiditis (PPT and the minority by Graves’ disease and non-autoimmune thyroiditis. PPT has a worldwide prevalence ranging from 1 to 22% and averaging 5% based on a review published in 2012. Several factors confer risk for the development of PPT. Typically, the clinical course of PPT is characterized by three phases: thyrotoxic, hypothyroid, and euthyroid phase. Approximately half of PPT women will have permanent hypothyroidism. The best humoral marker for predictivity, already during the first trimester of gestation, is considered positivity for thyroperoxidase autoantibodies (TPOAb, though only one-third to half of such TPOAb-positive pregnant women will develop PPT. Nutraceuticals (such as selenium or omega-3-fatty acid supplements seem to have a role in prevention of PPT. In a recent study on pregnant women with stable dietary habits, we found that the fish consumers had lower rates of positivity (and lower serum levels of both TPOAb and thyroglobulin Ab compared to meat eaters. Finally, we remind the reader of other diseases that can be observed in the postpartum period, either autoimmune or non-autoimmune, thyroid or non-thyroid.

    Full Text Available There are several interactions between thyroid and kidney functions in each other organ′s disease states. Thyroid hormones affect renal development and physiology. Thyroid hormones have pre-renal and intrinsic renal effects by which they increase the renal blood flow and the glomerular filtration rate (GFR. Hypothyroidism is associated with reduced GFR and hyperthyroidism results in increased GFR as well as increased renin - angiotensin - aldosterone activation. Chronic kidney disease (CKD is characterized by a low T3 syndrome which is now considered a part of an atypical nonthyroidal illness. CKD patients also have increased incidence of primary hypothyroidism and subclinical hypothyroidism. The physiological benefits of a hypothyroid state in CKD, and the risk of CKD progression with hyperthyroidism emphasize on a conservative approach in the treatment of thyroid hormone abnormalities in CKD. Thyroid dysfunction is also associated with glomerulonephritis often by a common autoimmune etiology. Several drugs could affect both thyroid and kidney functions. There are few described interactions between thyroid and renal malignancies. A detailed knowledge of all these interactions is important for both the nephrologists and endocrinologists for optimal management of the patient.

    To diagnosis and understand the pathophysiologic status of thyroid disease, not only hormonal measurements but also thyroid scan is believed to have a unique role. Especially in the cases of the change of the thyroid function by thyroiditis, it is emphasized that thyroid scan can be helpful in differential diagnosis, Discordant results of thyroid hormone levels and thyroid scan are found in transient hyperthyroidism, or in transient hypothyroidism. We analysed and reevaluated thyroid scan to look at the importance of thyroid scan. The results are summarised as follows: 1) 80%. of hyperthyroid patients had hyperthyroidism increased RAIU with even density, they are compatible with Graves' disease. 2) 2.1% of hyperthyroid patients had normal or decreased RAIU, which are classified as high iodine turn over genuine hyperthyroidism. 3) 8.5% of hyperthyroid patients had markedly decreased RAIU at both 2 hour and 24 hour, whose pathologic processes are suggested to be heterogenous namely subacute thyroiditis, postpartum thyroiditis, Hashimoto's thyroiditis, and pamless thyroiditis. 4) 45% of hypothyroid patients had increased 24 hr RAIU, 30% of hypothyroid patients were normal, 25%, decreased. In conclusion, thyroid scan should be reevaluated its useful role to asses the pathophysiologic status of thyroid disease. Especially in cases of transient thyrotoxicosis, thyroid scan is essential to diagnose and follow up the disease process.

    Full Text Available Assessment of thyroid disease in pregnancy is important for gestational maternal health, obstetric outcome and, subsequent development of child. Pregnancy has pro­found effects on the regulation of thyroid function, and on thyroidal functional disorders, that need to be recognized, carefully evaluated and correctly managed. In women with normal thyroid function there is an increase in thyroxine (T4 and triiodothyronine (T3 production and inhibition of thyroid-stimulating hormone (TSH in the first trimester of pregnancy,. In the pregnant woman, elevated thyroxine-binding globulin (TGB and concomitant increases in total T4 and T3 levels plateau at 12-14 weeks of pregnancy, and free T4 measurements slowly decrease. The most frequent thyroid disorder in pregnancy is maternal hy­pothyroidism. It is associated with fetal loss, placental abruptions, preeclampsia, preterm delivery and reduced intellectual function in the offspring. Hyperthyroidism dur­ing pregnancy is relatively uncommon, with a prevalence estimated to range between 0.1% and 1%. The most common cause of hyperthyroidism is Graves disease, as this etiology accounts for 85% of clinical hyperthyroid­ism in pregnancy. Another cause of hyperthyroidism is hyperemesis gravidarum. This is common and requires differentiation from Graves disease. There has been much discussion and many publications on the optimal management of pregnant women who are hyperthyroid or hypothyroid. Despite the lack of consensus organiza­tions, which are based on analyses, support screening in all pregnant women in the first trimester for thyroid disease. In this article, we provide information about the current approaches of thyroid dysfunction in pregnancy. J Clin Exp Invest 2016; 7 (1: 120-124

  7. Targeting thyroid diseases with TSH receptor analogs.

    2013-12-01

    The thyroid-stimulating hormone (TSH) receptor (TSHR) is a major regulator of thyroid function and growth, and is the key antigen in several pathological conditions including hyperthyroidism, hypothyroidism, and thyroid tumors. Various effective treatment strategies are currently available for many of these clinical conditions such as antithyroid drugs or radioiodine therapy, but they are not devoid of side effects. In addition, treatment of complications of Graves' disease such as Graves' ophthalmopathy is often difficult and unsatisfactory using current methods. Recent advances in basic research on both in vitro and in vivo models have suggested that TSH analogs could be used for diagnosis and treatment of some of the thyroid diseases. The advent of high-throughput screening methods has resulted in a group of TSH analogs called small molecules, which have the potential to be developed as promising drugs. Small molecules are low molecular weight compounds with agonist, antagonist and, in some cases, inverse agonist activity on TSHR. This short review will focus on current advances in development of TSH analogs and their potential clinical applications. Rapid advances in this field may lead to the conduct of clinical trials of small molecules related to TSHR for the management of Graves' disease, thyroid cancer, and thyroid-related osteoporosis in the coming years.

    Understanding the iodine kinetics in the thyroid is useful for the diagnosis of a patient with diffuse thyroid disease. In this study, 9 controls and 50 patients with diffuse thyroid diseases, we evaluated diffuse thyroid diseases with 123 I thyroidal uptake and volume, iodine concentration, and net iodine content measured by computed tomography. There was no significant correlation between volume, iodine concentration, and net iodine content of the thyroid and 123 I thyroidal uptake. The thyroid volume in Graves' and Hashimoto's diseases was significantly larger than that in the control group. The thyroid iodine concentration in Graves' and Hashimoto's diseases was significantly smaller than that in the control group. The thyroid net iodine content in Hashimoto's disease was significantly smaller than that in the control group. Although most of the patients with Graves' disease had more increased radioiodine thyroidal uptake than the control group, there was no significant difference between them in the mean of the thyroid net iodine content. But the variance of net iodine contents in the former was significantly larger than that in the latter. The thyroid net iodine content was very low in all patients with very high thyroglobulin hemaggrugated antibody (TGHA) value although it was nearly normal in some patients with normal TGHA value. It was suggested that iodine concentration and net iodine content might be determined not only by iodine uptake but also by release and/or leakage of iodine compounds from the thyroid, which might depend on some antithyroid antibodies.

    To evaluate the incidence of thyroid carcinoma in patients operated on for Graves' disease, to identify criteria which may predict malignancy, and to develop a practical approach to determine the extensiveness of thyroidectomy. Retrospective study of all patients who underwent thyroidectomy for Graves' disease between 1995 and 2005. 547 patients underwent subtotal thyroidectomy for Graves' disease during this period. Post-operative pathology examination revealed six cases of thyroid cancer (1.1%). All six cases had differentiated thyroid carcinoma (papillary carcinoma in 3 cases, follicular carcinoma in 2 cases and papillo-follicular carcinoma in 1 case). The indication for initial thyroidectomy was a palpable thyroid nodule in 3 cases (50%), failure of medical treatment for Grave's disease in 2 cases (33%), and signs of goiter compression in 1 case (17%). Five patients underwent re-operative total thyroidectomy. This study shows that while malignancy in Grave's disease is uncommon, the presence of thyroid nodule(s) in patients with Grave's disease may be considered as an indication for radical surgery. The most adequate radical surgery in this situation is to perform a total thyroidectomy.

    Adipogenesis contributes to the pathogenesis of thyroid eye disease (TED). Thyrotropin receptor (TSHR) transcripts are present in orbital fat. This study was conducted to determine whether they are expressed as functional protein, and if so, whether this is restricted to TED orbits or to a particular stage in adipocyte differentiation. Samples of fat were obtained from 18 TED-affected orbits and 4 normal orbits, and 9 were obtained from nonorbital locations. Frozen sections were examined by immunocytochemistry using monoclonal antibodies specific for the human TSHR. Samples were disaggregated and the preadipocytes separated from the mature by differential centrifugation and cultured in serum-free or DM and examined for morphologic changes, oil red O and TSHR staining, and TSH-induced cyclic adenosine monophosphate (cAMP) production. Marked immunoreactivity was observed in frozen sections from all three TED samples and faint staining in both normal orbital fat samples. In vitro, 1% to 5% of preadipocytes displayed TSHR immunoreactivity in five of six TED and two of three normal orbital samples and in three of five nonorbital samples. Differentiation, was induced in all 14 orbital samples. Three of four nonorbital samples contained occasional differentiated cells. Fifty percent to 70% of differentiating cells demonstrated receptor immunoreactivity. Two of three TED and four of four nonorbital preadipocytes in DM and/or mature adipocytes displayed a TSH-mediated increase in cAMP. The results indicate that orbital fat TSHR transcripts are expressed as protein, which can be functional. This is not aberrant in TED orbits, although expression may be upregulated. The majority of preadipocytes undergoing differentiation express the receptor, indicating a key role for this population in one mechanism for increasing orbital volume.

    The main role of vitamin D is regulating bone metabolism and calcium and phosphorus homeostasis. Over the past few decades, the importance of vitamin D in non-skeletal actions has been studied, including the role of vitamin D in autoimmune diseases, metabolic syndromes, cardiovascular disease, cancers, and all-cause mortality. Recent evidence has demonstrated an association between low vitamin D status and autoimmune thyroid diseases such as Hashimoto's thyroiditis and Graves' disease, and impaired vitamin D signaling has been reported in thyroid cancers. This review will focus on recent data on the possible role of vitamin D in thyroid diseases, including autoimmune thyroid diseases and thyroid cancers.

  12. Radiation-induced thyroid disease

    Maxon, H.R.

    1985-01-01

    Ionizing radiation has been demonstrated to result in a number of changes in the human thyroid gland. At lower radiation dose levels (between 10 and 1500 rads), benign and malignant neoplasms appear to be the dominant effect, whereas at higher dose levels functional changes and thyroiditis become more prevalent. In all instances, the likelihood of the effect is related to the amount and type of radiation exposure, time since exposure, and host factors such as age, sex, and heredity. The author's current approach to the evaluation of patients with past external radiation therapy to the thyroid is discussed. The use of prophylactic thyroxine (T4) therapy is controversial. While T4 therapy may not be useful in preventing carcinogenesis when instituted many years after radiation exposure, theoretically T4 may block TSH secretion and stimulation of damaged cells to undergo malignant transformation when instituted soon after radiation exposure

    Autoimmune thyroid diseases (AITD) show a female predominance, with an increased incidence in the years following parturition. Fetal microchimerism has been suggested to play a role in the pathogenesis of AITD. However, only the presence of fetal microchimeric cells in blood and in the thyroid gland of these patients has been proven, but not an actual active role in AITD. Is fetal microchimerism harmful for the thyroid gland by initiating a Graft versus Host reaction (GvHR) or being the target of a Host versus Graft reaction (HvGR)? Is fetal microchimerism beneficial for the thyroid gland by being a part of tissue repair or are fetal cells just innocent bystanders in the process of autoimmunity? This review explores every hypothesis concerning the role of fetal microchimerism in AITD. PMID:23723083

    Thyroid hormones are key regulators of skeletal development in childhood and bone homeostasis in adulthood, and thyroid diseases have been associated with increased osteoporotic fractures. Hypothyroidism in children leads to an impaired skeletal maturation and mineralization, but an adequate and timely substitution with thyroid hormones stimulates bone growth. Conversely, hyperthyroidism at a young age accelerates skeletal development, but may also cause short stature because of a premature fusion of the growth plates. Hypothyroidism in adults causes an increase in the duration of the remodeling cycle and, thus, leads to low bone turnover and enhanced mineralization, but an association with a higher fracture risk is less well established. In adults, a surplus of thyroid hormones enhances bone turnover, mostly due to an increased bone resorption driven by osteoclasts. Thus, hyperthyroidism is a well-recognized cause of high-bone turnover secondary osteoporosis, resulting in an increased susceptibility to fragility fractures. Subclinical hyperthyroidism, especially resulting from endogenous disease, also has an adverse effect on bone mineral density and is associated with fractures. In most patients with overt or subclinical hyperthyroidism restoration of the euthyroid status reverses bone loss. In postmenopausal women who receive thyroid-stimulating hormone suppression therapy because of thyroid cancer, antiresorptive treatments may be indicated. Overall, extensive data support the importance of a euthyroid status for bone mineral accrual and growth in childhood as well as maintenance of bone health in adulthood.

    Autoimmune diseases are chronic conditions initiated by the loss of immunological tolerance to self-antigens. They constitute heterogeneous group of disorders, in which multiple alterations in the immune system result in a spectrum of syndromes that either target specific organs or affect the body systematically. Recent epidemiological studies have shown a possible shift of one autoimmune disease to another or the fact that more than one autoimmune disease may coexist in a single patient or in the same family. Numerous autoimmune diseases have been shown to coexist frequently with thyroid autoimmune diseases. AUTOIMMNUNE THYROID DISEASE AND OTHER ORGAN SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: This part of the study reviews the prevalence of autoimmune thyroid disease coexisting with: pernicious anaemia, vitiligo, celiac disease, autoimmune liver disease, miastenia gravis, alopecia areata and sclerosis multiplex, and several recommendations for screening have been given. AUTOIMMUNE THYROID DISEASE AND OTHER ORGAN NON-SPECIFIC NON-ENDOCRINE AUTOIMMUNE DISEASES: Special attention is given to the correlation between autoimmune thyroid disease and rheumatoid arthritis, systemic lupus erythematosus, syndrome Sjögren, systemic sclerosis and mixed connective tissue disease. Screening for autoimmune thyroid diseases should be recommended in everyday clinical practice, in patients with primary organ-specific or organ non-specific autoimmune disease. Otherwise, in patients with primary thyroid autoimmune disease, there is no good reason of seeking for all other autoimmune diseases, although these patients have a greater risk of developing other autoimmune disease. Economic aspects of medicine require further analyzing of these data, from cost/benefit point of view to justified either mandatory screening or medical practitioner judgment.

    The best preoperative examination in Graves' disease with thyroid cancer still remains uncertain. The objectives of the present study were to investigate the prevalence of thyroid cancer in Graves' disease patients, and to identify the predictive factors and ultrasonographic features of thyroid cancer that may aid the preoperative diagnosis in Graves' disease. This retrospective study included 423 patients with Graves' disease who underwent surgical treatment from 2002 to 2012 at our institution. The clinical features and ultrasonographic findings of thyroid nodules were recorded. The diagnosis of thyroid cancer was determined according to the pathological results. Thyroid cancer was discovered in 58 of the 423 (13.7 %) surgically treated Graves' disease patients; 46 of those 58 patients had thyroid nodules, and the other 12 patients were diagnosed with incidentally discovered thyroid carcinomas without thyroid nodules. Among the 58 patients with thyroid cancer, papillary microcarcinomas were discovered in 50 patients, and multifocality and lymph node involvement were detected in the other 8 patients. Multivariate regression analysis showed younger age was the only significant factor predictive of metastatic thyroid cancer. Ultrasonographic findings of calcification and intranodular blood flow in thyroid nodules indicate that they are more likely to harbor thyroid cancers. Because the influencing factor of metastatic thyroid cancers in Graves' disease is young age, every suspicious nodule in Graves' disease patients should be evaluated and treated carefully, especially in younger patients because of the potential for metastasis.

    The thyroid gland is commonly included in the field of radiation therapy for patients with malignant lymphoma and with head and neck tumors. The radiation dose for malignant diseases varies considerably depending on the purpose of treatment and the institutional policies. A substantial number of these patients are developing subclinical and clinical hypothyroidism. The risk of developing hypothyroidism after a moderate radiation dose of 2000 to 4500 rads has been reported to be 10 to 20 percent. In addition, subclinical hypothyroidism is induced further in one third of the patients. There are also suggestions that external irradiation of the thyroid gland in patients with malignant lymphomas, as well as internal irradiation with radioiodine of the normal and hyperthyroid human thyroid glands, would induce elevations of serum antithyroid autoantibody titers. However, only a few cases of Graves disease following irradiation to the thyroid gland have been reported. We encountered a young woman who received radiation therapy to the mantle field for her Hodgkin's disease and developed hypothyroxinemia without overt signs and symptoms of hypothyroidism, followed by appearance of nodular goiter and then full-blown Graves disease

    Patients with Graves' disease were studied for two years during and after a twelve-month course of treatment. Disease activity was determined by repeated measurements of thyroidal uptake of [/sup 99m/Tc]pertechnetate during tri-iodothyronine administration. These in-vivo measurements of thyroid stimulation were compared with the results of in-vitro assays of Graves, immunoglobulin (TSH binding inhibitory activity--TBIA). There was no correlation between the thyroid uptake and TBIA on diagnosis. Pertechnetate uptake and TBIA both declined during the twelve months of antithyroid therapy. TBIA was detectable in sera from 19 of the 27 patients at diagnosis; in 11 of these 19 patients there was a good correlation (p less than 0.05) throughout the course of their disease between the laboratory assay of the Graves, immunoglobulin and the thyroid uptake. Probability of recurrence can be assessed but sustained remission of Graves' disease after treatment cannot be predicted from either measurement alone or in combination

    Scientifically substantiated figures of material costs spent on the main types of radiotherapy of thyroid diseases were calculated. Cost calculation was based on the principle of the use of means in the nonindustrial field of economy. The cost of each investigation was calculated as full expenses (main funds and current costs) allocated for a particular type of investigation in any arbitrary period of time, divided into the number of investigations performed over this period. Standardization of investigations taking account of the elaborated tactical schemes makes it possible to decrease notably (almost by 20%) material cost on the investigation of thyroid patients

Included in this study were 885 patients receiving detailed examination for suspected thyroid disease, consisting of 575 exposed persons (Group I) and 310 non-exposed persons (Group II). Thyroid diseases occurred in 157 (27 %) of Group I and in 65 (21 %) of Group II. According to the type of thyroid disease, thyroid cancer, thyroid adenoma, non-toxic uninodular and multinodular goiters were more common in Group I than Group II. The incidence of hypothyroidism was higher in Group I than Group II; however, the incidence of Graves' disease or chronic thyroiditis did not differ in the two groups. A trend toward a slightly higher incidence of thyroid cyst was observed in Group I than Group II. (Namekawa, K.)

    Thyroid autoimmune disease, a widespread phenomenon in female population, impairs thyroid function during pregnancy. Identifying cases, which will develop hypothyroidism during pregnancy, is crucial in the follow-up process. The study group comprised 108 females, with ages between 20-40 years; with known inactive autoimmune thyroid disease, before pregnancy that became pregnant in the study follow-up period. They were monitored by means of clinical, hormonal and immunological assays. Supplemental therapy with thyroid hormones was used, where needed. Maternal age and level of anti-thyroid antibodies were used to predict thyroid functional impairment.

Several USE methods have been developed, including Quasi-Static or Strain Elastography and Shear Wave Elastography. The utility of USE has been demonstrated in differentiating between malignant and benign thyroid lesions. Recently, USE has been applied in the evaluation of thyroiditis and autoimmune thyroid disease (AITD).Thyroid inflammatory illnesses constitute a diverse group of diseases and may manifest various symptoms. These conditions may share some parallel clinical, biochemical, and ultrasonographic features, which can lead to diagnostic difficulties. USE may be an additional tool, supporting other methods in the diagnosis and treatment monitoring of thyroid diseases, other than thyroid nodular disease.The aim of this article was to analyse and summarise the available literature on the applicability of different elastographic techniques in the diagnosis, differentiation and monitoring of various types of thyroiditis and AITD. Advantages and limitations of this technique are also discussed.

  7. New Genetic Insights from Autoimmune Thyroid Disease

    Full Text Available The autoimmune thyroid diseases (AITDs (Graves’ disease and Hashimoto’s thyroiditis are complex genetic diseases which most likely have more than 20 genes contributing to the clinical phenotypes. To date, the genes known to be contributing fall into two categories: immune regulatory genes (including HLA, CTLA4, PTPN22, CD40, CD25, and FCRL3 and thyroid-specific genes (TG and TSHR. However, none of these genes contribute more than a 4-fold increase in risk of developing one of these diseases, and none of the polymorphisms discovered is essential for disease development. Hence, it appears that a variety of different gene interactions can combine to cause the same clinical disease pattern, but the contributing genes may differ from patient to patient and from population to population. Furthermore, this possible mechanism leaves open the powerful influence of the environment and epigenetic modifications of gene expression. For the clinician, this means that genetic profiling of such patients is unlikely to be fruitful in the near future.

    AIM: To investigate those associations using data of the population-based Study of Health in Pomerania.METHODS: A study population of 3 749 residents aged 20-79 years without previously diagnosed thyroid disease was available for analyses. Serum TSH was used to assess thyroid function. Cholelithiasis was defined by either a prior history of cholecystectomy or the presence of gallstones on ultrasound. Logistic regression was performed to analyze independent associations between thyroid function and cholelithiasis.RESULTS: There were 385 persons (10.3%) with low (<0.3 mIU/L), 3 321 persons (88.6%) with normal and 43 persons (1.2%) with high serum TSH levels (>3 mIU/L).The proportion of cholelithiasis among males and females was 14.4% and 25.3%, respectively. Among males, there was an independent relation between high serum TSH and cholelithiasis (OR 3.77; 95%-CI 1.06-13.41; ,P<0.05). zAlso among males, there was a tendency towards an elevated risk of cholelithiasis in persons with low serum TSH (OR 1.40; 95%-CI 0.96-2.02; P = 0.07). In the female population, no such relation was identified.CONCLUSION: There is an association between thyroid and gallstone disease with a gender-specific relation between hypothyroidism and cholelithiasis.

    Understanding the iodine kinetics in the thyroid is useful for the diagnosis of a patient with diffuse thyroid disease. In this study, 9 controls and 50 patients with diffuse thyroid diseases, we evaluated diffuse thyroid diseases with {sup 123}I thyroidal uptake and volume, iodine concentration, and net iodine content measured by computed tomography. There was no significant correlation between volume, iodine concentration, and net iodine content of the thyroid and {sup 123}I thyroidal uptake. The thyroid volume in Graves' and Hashimoto's diseases was significantly larger than that in the control group. The thyroid iodine concentration in Graves' and Hashimoto's diseases was significantly smaller than that in the control group. The thyroid net iodine content in Hashimoto's disease was significantly smaller than that in the control group. Although most of the patients with Graves' disease had more increased radioiodine thyroidal uptake than the control group, there was no significant difference between them in the mean of the thyroid net iodine content. But the variance of net iodine contents in the former was significantly larger than that in the latter. The thyroid net iodine content was very low in all patients with very high thyroglobulin hemaggrugated antibody (TGHA) value although it was nearly normal in some patients with normal TGHA value. It was suggested that iodine concentration and net iodine content might be determined not only by iodine uptake but also by release and/or leakage of iodine compounds from the thyroid, which might depend on some antithyroid antibodies.

    Objective: To study the pathological morphology of thyroid specimen after thyroid arteries embolization. In order to select appropriate size of embolizing granules, the diameters of thyroid arteries in Graves' disease were measured. Methods: Multiple slides of embolized thyroid tissues from superior pole, body and inferior pole of the resected thyroid glands were made. After being embedded and stained, pathological morphology was observed and diameters of arteries in various parts of thyroid glands were measured under microscopy. Results: Pathological examination of thyroid glands showed that superior and inferior thyroid arteries and most of their branches were embolized with ischemic necrosis and fibrosis in the embolized thyroid tissue. Follicular epithelium appeared as flat or cubic shapes with colloid reduction. Average diameter of main branches of superior artery was 440-550 μm and that of inferior artery was 300-375 μm. The diameters of capillary network in the thyroid body was 120-250 μm, and the non-embolized ones was 40-110 μm. The diameter of isthmus was 130-150 μm. Conclusions: Pathological morphology of Graves' disease after thyroid arteries embolization showed that the excretion of thyroid glands would be decreased and equivalents to subtotal thyroidectomy

    This work studies the thyroid disorders impact on adrenals glands by measuring total cortisol. Radioimmunoassays of thyroid hormones and cortisol were performed in 108 subjects, aged 20-52 years, with thyroid diseases. Our results show low cortisol values (80.35 nmol/L) in 4.77% of hyperthyroids, high values in 3.57% of hyperthyroids (1348.18 nmol/L) and 12.5% of hypothyroids (969.05 nmol/L). In hyperthyroidism, thyroid hormone stimulates the secretion of 11 ceto metabolites biologically inactive, unable to slow pituitary activity, inducing an increased production of endogene cortisol. Excessive catabolism can lead to the exhausting of overstimulated adrenal glands, and therefore to a decreased cortisol. In hypothyroidism, high cortisol results of increase cortisol half life and decrease of metabolic clearance. Control mechanisms often allow normal cortisol values. These alterations in functional activity of adrenal glands, seen in nearly 10% of these subjects, sometimes command a specific attitude in diagnosis and therapy.

    In 63 patients echography of thyroid was performed additionally to case history, palpation, scintigraphy and hormone tests for evaluating clinical significance of this method. The benefit of this technique is rapid measurement of thyroid size, demonstration of nodules in palpable diffuse goiters and differentiating of solid or cystic nodules of the thyroid. For diagnosis of autonomous areas in the thyroid scintigrahy remains the method of choice. Also there is no correlation of ultrasound findings and thyroid function. In routine diagnostic procedure of thyroid disease echography may replace scintigraphy only in diffuse goiter and if radionuclide imaging is not possible. Nevertheless ultrasonic evaluation of the thyroid is an important additional method in diagnostic of thyroid diseases. (Author)

    Surgical management of thyroid diseases (BTDs) has been a topic of interest and confusion for many years. Almost 80% of thyroidectomies at an average endocrine surgical unit are carried out for BTDs.Resistance to surgical intervention in BTDs has been based on the belief that increased complication rate is inherent in its use, this is despite thepotential advatages in terms of confirming the benign nature of the lesion, controlling the disease, and relieving of local symptoms of large neck mass. Benign thyroid diseases are more likely to occur in middle-aged woman living in iodine deficient areas, or have a family history of goiter, or in patients taking iodine-containig drugs, like amoidarone, or in patients with previous history of x-ray exposure. However, the physician must be carefull in making the diagnosis of BTDsin patients of extremes of age or in presence of positive history of radiation, or in patients with family history of thyroid or colon cancer . In this atricle we will review the etiology,epidemiology , diagonastic methodologiesand the recent trends in the sugical and medical mangement of BTDs. (author)

    The purpose of the study - to determine the feature of the vascular endothelial growth factor (VEGF) and thyroid-stimulating hormone (TSH) expression in the thyroid gland (TG) in various thyroid diseases. Material - thyroid tissue (operative material) with histologically confirmed diagnosis: 10 - follicular adenoma, 17 - multinodular goiter, 8 - thyroiditis Hashimoto, 8 - papillary carcinoma, 10 - intact (normal) thyroid samples (forensic autopsy). The immunohistochemical study of the material showed the following results: the increase of the Hürtle cells population 40 % or more indicates a hyperthyroidism tendency despite TSH+ receptor status. Under the thyroid pathology TSH and VEGF expression appears in thyrocytes and also in microvascular endothelial cells. VEGF expression is below the norm in the Hashimoto thyroiditis. VEGF is involved not only in angiogenesis, but in pathophysiological shifts in thyroid tissue. Microvessel density (MVD) and TSH positive receptor status under the thyroid pathology testify the absence of the endothelial cells transformation, however, this index can not serve as a biopothential prognostic marker of thyroid disease.

    Topical problems concerning diagnostics, therapy and ecology of thyroid diseases were discussed on an international level at this symposium. As the problems are mostly medical in nature, the symposium started with papers on the anatomy, physiology, and pathology of the thyroid, followed by lectures on dose calculation and dose/effect relationships. Particular attention is paid to the distinction between external radiation exposure and incorporation of radioactive materials, especially iodine. Another section of the symposium was dedicated to the establishment of radiation hazards. The symposium ended with a discussion of the value of diagnostic and therapeutical procedures. The extensive discussions between experts from different nations and different fields of science have surely helped to deepen the knowledge on radiation effects. (orig./MG) [de

    The risk of thyroid cancer increases and persists for decades among individuals exposed to ionizing radiation in childhood, although the long-term effects of childhood exposure to medium to low doses of radiation on thyroid dysfunction and autoimmune thyroid diseases have remained unclear. To evaluate radiation dose responses for the prevalence of thyroid dysfunction and autoimmune thyroid disease among atomic bomb survivors exposed in childhood. Hiroshima and Nagasaki atomic bomb survivors who were younger than 10 years old at exposure underwent thyroid examinations at the Radiation Effects Research Foundation between 2007 and 2011, which was 62 to 66 years after the bombing. Data from 2668 participants (mean age, 68.2 years; 1455 women) with known atomic bomb thyroid radiation doses (mean dose, 0.182 Gy; dose range, 0 to 4.040 Gy) were analyzed. Dose-response relationships between atomic bomb radiation dose and the prevalence of hypothyroidism, hyperthyroidism (Graves' disease), and positive for antithyroid antibodies. Prevalences were determined for hypothyroidism (129 cases, 7.8%), hyperthyroidism (32 cases of Graves' disease, 1.2%), and positive for antithyroid antibodies (573 cases, 21.5%). None of these was associated with thyroid radiation dose. Neither thyroid antibody-positive nor -negative hypothyroidism was associated with thyroid radiation dose. Additional analyses using alternative definitions of hypothyroidism and hyperthyroidism found that radiation dose responses were not significant. Radiation effects on thyroid dysfunction and autoimmune thyroid diseases were not observed among atomic bomb survivors exposed in childhood, at 62 to 66 years earlier. The cross-sectional design and survival bias were limitations of this study. Copyright © 2017 Endocrine Society

    The objective of the Hanford Environmental Dose Reconstruction (HEDR) Project is to estimate the radiation doses that specific and representative individuals and populations may have received as a result of releases of radioactive materials from historical operations at the Hanford Site. These dose estimates would account for the uncertainties of information regarding facilities operations, environmental monitoring, demography, food consumption and lifestyles, and the variability of natural phenomena. Other objectives of the HEDR Project include: supporting the Hanford Thyroid Disease Study (HTDS), declassifying Hanford-generated information and making it available to the public, performing high-quality, credible science, and conducting the project in an open, public forum.

    Thyroid imaging is indicated to evaluate congenital hypothyroidism during newborn screening or in cases of a palpable thyroid mass in children and adolescents. This pictorial essay reviews the ultrasonography (US) of thyroid diseases in children and adolescents, including normal thyroid gland development, imaging features of congenital thyroid disorders (dysgenesis, [aplasia, ectopy, hypoplasia], dyshormonogenesis, transient hypothyroidism, thyroglossal duct cyst), diffuse thyroid disease (Grave's disease, Hashimoto's thyroiditis, and suppurative thyroiditis), and thyroid nodules. The primary imaging modalities for evaluating thyroid diseases are US and radionuclide scintigraphy. Additionally, US can be used to guide aspiration of detected nodules.

    The incidence of thyroid carcinoma is increasing worldwide. Graves' disease is the most common hyperthyroid disease. Studies have suggested an increased risk of thyroid malignancy in Graves' disease: there has not yet been a meta-analysis to allow quantitative comparison. The purpose of this study was to determine the risk of thyroid carcinoma in Graves' disease, and to gather information on the histological subtypes of carcinoma and the co-existence of thyroid nodules. Several databases and article reference lists were searched. Inclusion criteria included appropriate diagnostic criteria for thyroid conditions and a diagnoses of carcinoma based on histology. 33 studies were selected, all reporting on surgically-resected specimens. The event rate of thyroid carcinoma in Graves' disease was 0.07 (95% CI 0.04 to 0.12). There was no data to allow comparison with patients without hyperthyroid diseases. There was no increase in the odds of developing carcinoma in Graves' disease compared to toxic multinodular goitre and toxic uninodular goitre. 88% of thyroid carcinomas in Graves' disease were papillary, with solitary papillary micro-carcinoma (diameter 10 mm or less) comprising 23% of all detected thyroid carcinomas. Patients with Graves' disease and co-existing thyroid nodules were almost 5 times more likely to be diagnosed with thyroid carcinoma than those without nodules. Thyroid malignancy in Graves' disease requiring surgical treatment should be considered as likely as in other hyperthyroid diseases needing surgical treatment. Clinicians should consider screening selected patients with Graves' disease for nodules whilst being aware of potentially over-diagnosing papillary micro-carcinoma. Crown Copyright © 2015.

    The objective of this study was to investigate apoptosis in the thyroid of Graves disease (GD) induced by thyroid arterial embolization. Forty one patients with clinically and laboratorily ascertained GD were treated with thyroid arterial embolization and followed up for 3-54 months following embolization. Prior to embolization and at 1, 3, 6, 12 and 36 months following embolization, thyroid autoimmune antibodies were tested respectively, including thyroid stimulating antibody (TSAb), thyroglobulin antibody (TGAb) and thyroid microsomal antibody (TMAb). Thyroid biopsy was performed under the guidance of computed tomography for immunohistochemistry examination using semi-quantity analysis. The positive staining of Fas and FasL was mostly in the cytoplasma and cell membrane, the positive expression of Bax was mainly in the cytoplasma, and no positive expression of P53 was detected in the thyroid cells before embolization. After arterial embolziation, the positive cell number and staining degree of these genes were both greater than before embolization. The treatment method of thyroid arterial embolization can effectively enhance the positive expression of pro-apoptotic genes of Fas, FasL, Bax, Bcl-2 and P53 in GD thyroid, thus promoting apoptosis of GD thyroid and helping restore the thyroid size and function to normal conditions.

RECENT FINDINGS: Epidemiological data suggest an increased prevalence of autoimmune thyroid...... diseases under conditions of low dietary selenium intake. Two systematic reviews have evaluated controlled trials among patients with autoimmune thyroiditis and report that selenium supplementation decreases circulating thyroid autoantibodies. The immunomodulatory effects of selenium might involve reducing...... proinflammatory cytokine release. However, clinically relevant effects of selenium supplementation, including improvement in quality of life, are more elusive.

    The incidence of hyperparathyroidism was prospectively evaluated in a group of patients with thyroid disease, and the incidence of thyroid disease was retrospectively evaluated in a group of patients specifically referred for evaluation of hyperparathyroidism. Hyperparathyroidism was ten times more frequent in thyroid patients than expected in a general medical population and was especially prevalent in patients with nodular goiter. The incidence of thyroid disease in patients with hyperparathyroidism was 38.8%. Although radiation therapy was shown to be a factor in these associations, it alone could not explain the observed frequency

    The main physiological role of iodine in the body is to synthesize thyroid hormone. Both iodine deficiency and iodine excess can lead to severe thyroid diseases. While its role in thyroid diseases has increasingly been recognized, few relevant platforms and techniques for iodine detection have been available in China. This paper summarizes the advantages and disadvantages of currently iodine detection methods including direct titration, arsenic cerium catalytic spectrophotometry, chromatography with pulsed amperometry, colorimetry based on automatic biochemistry, inductively coupled plasma mass spectrometry, so as to optimize the iodine nutrition for patients with thyroid diseases.

    The thyroid function of 64 patients with Hodgkin's disease who received mantle irradiation during the period 1966 to 1976 was studied. More than two-thirds (44 to 64) had some thyroid dysfunction. Twenty had mild dysfunction manifested by an abnormal thyroid-stimulating hormone response to thyrotropin-releasing hormone. Twenty had what could be termed compensated hypothyroidism while four were overtly hypothyroid. The severity of dysfunction was not related to age, sex, or chemotherapy. We found, however, that decreased thyroid function was inversely proportional to the length of time between a diagnostic lymphangiogram and the radiation therapy. These results are consistent with the hypothesis that the iodine load of the lymphangiogram renders the thyroid gland more radiosensitive. Thyroxine suppression of the thyroid gland during the period from the lymphangiogram through the termination of radiation therapy is suggested as a means of avoiding thyroid injury

    It has been suggested that breast and thyroid diseases may be linked. The aim of this study was to investigate the association between benign breast disease and subsequent risk of thyroid cancer. Postmenopausal women (n = 133,875) aged 50-79 years were followed up for a mean of 14 years. Benign breast disease was defined by history of biopsy. Incident thyroid cancer cases were confirmed by medical record review. Multivariable Cox proportional hazard modeling was used to estimate hazard ratios. There were 370 incident thyroid cancer cases during the follow-up period. Compared to women without BBD, women with BBD had a significant increased risk of thyroid cancer after adjusting for potential confounders (HR 1.38 95% CI 1.10-1.73), especially for women with more than two biopsies (HR 1.59 95% CI 1.10-2.26). There were no significant differences in thyroid tumor size, stage or histologic types between women with and without BBD. Our large prospective study observed that postmenopausal women with BBD had an increased risk for thyroid cancer compared with women without BBD. A more detailed investigation of thyroid cancer risk according to different subtypes of benign breast disease is needed to better understand the association observed between thyroid and benign breast diseases.

    Selenium plays a significant role in the thyroid function and its deficiency is considered by some authors to be a cause of thyroid disorders. The potential therapeutic influence of selenium supplementation in thyroid disease was investigated in several studies and some results were encouraging, however results were inconsistent and did not allow conclusion to be drawn. For that reason, we have performed a review study on relevance of selenium supplementation in thyroid disease. Till now, there is no strong evidence that selenium supplementation leads to clinical improvement in the course of autoimmune thyroiditis, nodular goitre or thyroid cancer. On the other hand, there is some evidence that selenium is effective in the treatment of orbitopathy; thus, the European Group on Graves' Orbitopathy (EUGOGO) recommends selenium administration in mild active orbitopathy.

    Full Text Available In recent years, the authors of epidemiological studies have documented that autoimmune diseases are a major problem of modern society and are classified as diseases of civilization. Autoimmune thyroid diseases (ATDs are caused by an abnormal immune response to autoantigens present in the thyroid gland – they often coexist with other autoimmune diseases. The most common dysfunctions of the thyroid gland are hypothyroidism, Graves-Basedow disease and Hashimoto’s disease. Hashimoto’s thyroiditis can be the main cause of primary hypothyroidism of the thyroid gland. Anthropometric, biochemical and physicochemical parameters are used to assess the nutritional status during the diagnosis and treatment of thyroid diseases. Patients with hypothyroidism are often obese, whereas patients with hyperthyroidism are often afflicted with rapid weight loss. The consequence of obesity is a change of the thyroid hormones’ activity; however, weight reduction leads to their normalization. The activity and metabolic rate of thyroid hormones are modifiable. ATDs are associated with abnormalities of glucose metabolism and thus increased risk of developing diabetes mellitus type 1 and type 2. Celiac disease (CD also increases the risk of developing other autoimmune diseases. Malnutrition or the presence of numerous nutritional deficiencies in a patient’s body can be the cause of thyroid disorders. Coexisting deficiencies of such elements as iodine, iron, selenium and zinc may impair the function of the thyroid gland. Other nutrient deficiencies usually observed in patients suffering from ATD are: protein deficiencies, vitamin deficiencies (A, C, B6, B5, B1 and mineral deficiencies (phosphorus, magnesium, potassium, sodium, chromium.

    Autoimmune thyroid disease is amongst the most frequent endocrine disorders during pregnancy. It is associated with an increase in perinatal morbidity, congenital defects, neurological damage, fetal and neonatal thyroid dysfunction. Maternal thyroid hormones play a key role in child neurodevelopment. We aimed to evaluate the thyroid function and the clinical course of neonates born from mothers with autoimmune thyroid disease during the first months of life in order to define the follow-up. We monitored thyroid function and clinical status during the first months in 81 newborns of mothers with autoimmune thyroid disease; 16 had Graves disease and 65 autoimmune thyroiditis. A percentage of 4.93 newborns had congenital defects, and 8.64% neonates showed an increase in thyrotropin (TSH) (>9.5 μUI/mL 2 times) and required thyroxin within the first month of life. A 85.7% of these showed a negative newborn screening (due to a later increase of TSH). A higher TSH value in the newborn was related to an older age of the mother, higher levels of thyroid peroxidase (TPO) antibody during pregnancy and lower birth weight. A higher free thyroxine (FT4) value in the newborn was related to fewer days of life and mothers with Graves disease. We recommend the evaluation of TSH, T4 and TPO antibodies before 10 weeks in all pregnant women with follow-up if maternal thyroid autoimmunity or disorders is detected. It is also recommended to test children's serum TSH and FT4 at 48 h of life in newborns of mothers with autoimmune thyroid disease and repeat them between the 2nd and 4th week in children with TSH>6 μUI/mL. Careful endocrine follow-up is advised in pregnant women and children if hyperthyroidism is detected. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

    Diabetes mellitus and thyroid disease are known to mutually influence each other. Thyroid disease can worsen glycaemic control in diabetes, and patients with diabetes mellitus have increased incidence of thyroid disorders such as increase in size, compared to the normal population. The aim of the study was to sonographically assess thyroid gland volume in Nigerian adult diabetic patients and compare with apparently healthy adults (controls). The study setting was the Department of Radiology, University of Benin Teaching Hospital (UBTH) Nigeria. The thyroid gland in 120 diabetic subjects and equal number of apparently healthy controls was scanned with a 5-12 MHz linear transducer of a SONOACE X4 Machine. Thyroid gland volume was assessed. Statistical analysis was done with Statistical Package for the Social Sciences (SPSS) version 17 (SPSS Inc, Chicago, IL, USA). Diabetics had significantly increased thyroid volume compared to age matched male and female control subjects (11.5 ± 5.2 cm3 vs 7.4 ± 1.9 cm3; Pthyroid volume among diabetics. Diabetics have higher thyroid gland dimensions, compared to apparently healthy subjects. Gland proliferation from circulating insulin may play a role. This is not influenced by gender.

    Decreased cardiac metaiodobenzylguanidine (MIBG) uptake was reported in Parkinson's disease and this contributes to the differential diagnosis between Parkinson's disease and other forms of parkinsonism such as multiple system atrophy. However, decreased MIBG uptake of the thyroid has not been demonstrated. The objective of this study was to compare MIBG uptake of the thyroid among Parkinson's disease, multiple system atrophy and controls. Twenty-six patients with Parkinson's disease, 11 patients with multiple system atrophy and 14 controls were examined in this study. Planar images were taken 15 minutes (early images) and 3 hours (late images) after intravenous injection of 111 MBq 123 I-MIBG. MIBG uptake of the thyroid on early images decreased significantly in Parkinson's disease compared to controls (p<0.0001) and multiple system atrophy (p=0.018). MIBG uptake of the thyroid on early images decreased significantly also in multiple system atrophy compared to controls (p=0.027). On late images, thyroid uptake differed significantly only between Parkinson's disease and controls (p=0.010). Our study is the first to demonstrate decreased MIBG uptake of the thyroid in Parkinson's disease. Sympathetic nervous denervation of Parkinson's disease occurred not only in the heart but also in the thyroid. (author)

    Graves' disease is an autoimmune disorder that may present with various clinical manifestations of hyperthyroidism. Patients with Graves' disease have a greater number of thyroid nodules and a higher incidence of thyroid cancer compared with patients with normal thyroid activity. However, cases in which patients are diagnosed with recurrence of Graves' disease shortly after partial thyroidectomy for thyroid cancer are very rare. Here we report a case of hyperthyroid Graves' disease that occurred after partial thyroidectomy for papillary thyroid cancer. In this case, the patient developed hyperthyroidism 9 months after right hemithyroidectomy, and antithyroglobulin autoantibody and thyroid stimulating hormone receptor stimulating autoantibody were positive. Therefore, we diagnosed Graves' disease on the basis of the laboratory test results and thyroid ultrasonography findings. The patient was treated with and maintained on antithyroid drugs. The mechanism of the recurrence of Graves' disease in this patient is still unclear. The mechanism may have been the improper response of the immune system after partial thyroidectomy. To precisely determine the mechanisms in Graves' disease after partial thyroidectomy, further studies based on a greater number of cases are needed.

    In thyroid eye disease, visual loss due to optic nerve compression by enlarged muscles near the orbital apex requires prompt surgical decompression and must be differentiated from visual loss due to other mechanisms. Seventy-two high-resolution orbital CT scans of patients with thyroid eye disease were analyzed. From a coronal reconstruction, an easily measured ''apical index'' was determined. Average apical indices for orbits without optic neuropathy (41.0%) and with optic neuropathy (70.2%) were significantly different (P < .001). With the aid of the apical index, CT findings can be used to predict which patients with thyroid eye disease have optic nerve compression

There was no definite differences in clinical and thyroid functions between the groups with positive and negative results. 4) Both antibodies were positive in 16 (88.9%) and 17 (94.4%) patients respectively among 18 patients with Hashimoto's thyroiditis, all of them were diagnosed histologically. 5) Three out of 33 patients with thyroid adenoma showed positive antibodies, and 3 of 16 patients with thyroid carcinoma revealed positive antibodies. 6) TRCH antibodies demonstrated negative results in 2 patients with subacute thyroiditis, but positive in one patient with idiopathic primary myxedema. 7) The number of patients with high titers(>l:802) was 16 for antithyroglobulin antibody, and 62.5% (10 patients) of which was Hashimoto's thyroiditis. Thirteen (65.0) of 20 patients with high titers (>l:802) for antimicrosomal antibody was Hashimoto's thyroiditis. TRCH test is a simple, sensitive method, and has high reliability and reproducibility. The incidences and titers of antithyroglobulin antibody and antimicrosomal antibody are especially high in Hashimoto's thyroiditis.

    Thyroid imaging in pediatric patients is indicated for the evaluation of congenital hypothyroidism (CH) during newborn screening or for a palpable thyroid mass. The primary imaging modalities for newborn screening are ultrasonography (US) and radionuclide scintigraphy. US is useful as a first-line test for the diagnosis of thyroid abnormalities and lymphadenopathy in pediatric patients. In addition, US can be used to guide the aspiration of detected nodules and to support the evaluation of the lymph nodes.

    Background/Aim Operating far from its equilibrium resting point, the thyroid gland requires stimulation via feedback-controlled pituitary thyrotropin (TSH) secretion to maintain adequate hormone supply. We explored and defined variations in the expression of control mechanisms and physiological responses across the euthyroid reference range. Methods We analyzed the relational equilibria between thyroid parameters defining thyroid production and thyroid conversion in a group of 271 thyroid-healthy subjects and 86 untreated patients with thyroid autoimmune disease. Results In the euthyroid controls, the FT3-FT4 (free triiodothyronine-free thyroxine) ratio was strongly associated with the FT4-TSH ratio (tau = −0.22, p < 0.001, even after correcting for spurious correlation), linking T4 to T3 conversion with TSH-standardized T4 production. Using a homeostatic model, we estimated both global deiodinase activity and maximum thyroid capacity. Both parameters were nonlinearly and inversely associated, trending in opposite directions across the euthyroid reference range. Within the panel of controls, the subgroup with a relatively lower thyroid capacity (<2.5 pmol/s) displayed lower FT4 levels, but maintained FT3 at the same concentrations as patients with higher functional and anatomical capacity. The relationships were preserved when extended to the subclinical range in the diseased sample. Conclusion The euthyroid panel does not follow a homogeneous pattern to produce random variation among thyroid hormones and TSH, but forms a heterogeneous group that progressively displays distinctly different levels of homeostatic control across the euthyroid range. This suggests a concept of relational stability with implications for definition of euthyroidism and disease classification. PMID:27843807

    The thyroid gland was one of the first organs imaged in nuclear medicine, beginning in the 1940s. Thyroid scintigraphy is based on a specific phase or prelude to thyroid hormone synthesis, namely trapping of iodide or iodide analogues (ie, Tc99m pertechnetate), and in the case of radioactive iodine, eventual incorporation into thyroid hormone synthesis within the thyroid follicle. Moreover, thyroid scintigraphy is a reflection of the functional state of the gland, as well as the physiological state of any structure (ie, nodule) within the gland. Scintigraphy, therefore, provides information that anatomical imaging (ie, ultrasound, computed tomography [CT], magnetic resonance imaging) lacks. Thyroid scintigraphy plays an essential role in the management of patients with benign or malignant thyroid disease. In the former, the structure or architecture of the gland is best demonstrated by anatomical or cross-sectional imaging, such as ultrasound, CT, or even magnetic resonance imaging. The role of scintigraphy, however, is to display the functional state of the thyroid gland or that of a clinically palpable nodule within the gland. Such information is most useful in (1) patients with thyrotoxicosis, and (2) those patients whose thyroid nodules would not require tissue sampling if their nodules are hyperfunctioning. In neoplastic thyroid disease, thyroid scintigraphy is often standard of care for postthyroidectomy remnant evaluation and in subsequent thyroid cancer surveillance. Planar radioiodine imaging, in the form of the whole-body scan (WBS) and posttherapy scan (PTS), is a fundamental tool in differentiated thyroid cancer management. Continued controversy remains over the utility of WBS in a variety of patient risk groups and clinical scenarios. Proponents on both sides of the arguments compare WBS with PTS, thyroglobulin, and other imaging modalities with differing results. The paucity of large, randomized, prospective studies results in dependence on consensus

    The incidence of most thyroid diseases: hypothyroidism, nodular goitre, and cancer is highest among postmenopausal and elderly women. The diagnosis of thyroid dysfunction in this group of patients is difficult because the symptoms can be nonspecific or common with menopausal and ageing complaints. In the interpretation of thyroid function tests the physiological changes in secretion and metabolism of thyrotropin (TSH) and thyroid hormones must be considered, as well as the influence of comorbidities. Unrecognised thyroid dysfunction leads to increased: cardiovascular risk, bone fractures, cognitive impairment, depression, and mortality. Therapy of thyroid dysfunction is different in postmenopausal and elderly women than in young people; hypothyroidism should be treated with caution, because high doses of L-thyroxine can lead to cardiac arrhythmias and increased bone turnover, and hyperthyroidism should be preferentially treated with radioiodine. Thyroid status beneficially influencing longevity relates to low thyroid function. Thyroid nodules and cancer often affect women over 50 years old; the diagnostic and therapeutic approach is the same as in the general population, but the surgical risk and cancer prognosis is worse than in young patients.

    Background: Anti-thyroid peroxidase antibodies have a pathogenic role in Hashimoto thyroiditis. Between 10 and 19% of individuals without thyroid disease, have positive titers of these antibodies. Aim: To study the frequency of positive titers of anti-thyroid peroxidase antibodies in healthy individuals. Material and Methods: A blood sample, to measure anti-thyroid peroxidase antibodies and thyroid stimulating hormone (TSH) by chemiluminescence assay, was obtained from 67 women and 62 men aged 45 ± 14 years, without a personal or familiar history of thyroid diseases and normal thyroid palpation. The cutoff point of the manufacturer to consider positive a titer of anti-thyroid peroxidase antibodies was set at 35 IU/ml. Results: Twenty-eight women and 28 men had positive antibody titers (43% of the sample). Subjects in the upper tercile of anti-thyroid peroxidase antibody titers had a higher TSH than those in the second tercile, although within normal limits (1.73 ± 0.74 and 1.37 ± 0.59 mlU/L, respectively p = 0.02) Conclusions: Forty three percent of the studied subjects without personal or familial history of thyroid diseases had positive titers of anti-thyroid peroxidase antibodies. Further prospective studies should evaluate whether this observation discloses an increase in thyroid autoimmune disease in a population with increased iodine intake

    A thyroid screening program for individuals who had irradiation to the head and neck areas was started at Roswell Park Memorial Institute in February 1977 and by June 1979, 1,071 patients were seen in the clinic. Three hundred and ninety-six patients were found to have palpable abnormalities of the thyroid, and following pretreatment evaluation, suppressive therapy with triiodothyronine (T3) (50 μg/day) or DT (desiccated thyroid) (120 mg/day) was administered in a double-blind fashion. Two hundred fifty patients with nodular disease completed 6 mo of treatment and are analyzed in this paper. Pretreatment thyroid function tests showed that two patients had hypothyroidism with a high thyroid-stimulating hormone (TSH) and a low thyroxine level. A high incidence of thyroid autoantibodies was also noted and surgical findings confirmed a high incidence of chronic thyroiditis. Complete disappearance of the nodules was seen in 29% of the patients, and in addition, 38% of the patients were seen to have significant shrinkage of the nodules, indicating that radiation-associated thyroid nodules were as sensitive to the thyroactive agents as nonirradiated nodular thyroid disease. There was little difference in the response rate between T3 and DT. Both agents suppressed circulating TSH levels to an unmeasurable level in 76% of the patients. There was no correlation between scan findings and response rates. Thyroid carcinoma was found in 19% of the patients who underwent surgery; although all were well-differentiated carcinomas, two-thirds of the patients already had evidence of dissemination and/or invasion suggesting the aggressive nature of postirradiation thyroid carcinoma.

    Thyroid dysfunction can develop in patients with Hodgkin's disease who are treated with mantle irradiation. During the period 1970-89, the records of 320 patients who received mantle irradiation and who had thyroid function tests (TFT) were retrospectively reviewed. The median age was 30 years (range, 7-69 years). The median mantle and thyroid dose was 36 Gy (range, 30-40 Gy) and 39.8 Gy (range, 32-65 Gy), respectively. Overall thyroid dysfunction was present in 39% of the patients. Clinical hypothyroidism was seen in 10% and biochemical hypothyroidism was noted in 25%. Hyperthyroidism was found in 4% of patients. Thyroid nodules had developed in six patients (2%), of which those in four patients were malignant. Age, sex, histological subtype, stage of disease, dose, Iymphangiogram and treatment with chemotherapy were not significant factors in the development of thyroid dysfunction. The narrow dose range prevented adequate analysis of dose effect. The results indicate that the incidence of thyroid abnormalities is high enough to warrant regular TFT assessment with pre-irradiation levels and follow-up testing for life because the development of abnormalities can occur many years later. Thyroid examination should form part of the routine follow-up examination and any abnormality should be promptly investigated. Copyright (1998) Blackwell Science Pty Ltd

    Several groups of patients with normal and abnormal thyroid function as well as patients with goitre on hormone substitution are discussed with respect to the diagnostic value of the free thyroid hormone methods. The free T 3 technique under investigation separates clearly between euthyroidism and hyperthyroidism, however, during application of contraceptive pills and during pregnancy free T 3 is slightly enhanced. Free T 4 can be found in the normal range even in hypothyroidism, during T 4 substitution free T 4 is useful for control of adequate hormone substitution. Free thyroid hormones are advantageous to be performed with respect to practicability compared to the estimation of total hormone concentrations by enzyme as well as radioimmunoassay. Normally there is no additional demand for measurement of thyroid hormone binding proteins, another rather economical argument for using these parameters in thyroid diagnosis. (orig.) [de

    Full Text Available Abstract Background Children are commonly referred to a pediatric rheumatology center for the laboratory finding of an Anti-nuclear antibody (ANA of undetermined significance. Previous studies regarding adult rheumatology patients have supported an association between ANA and anti-thyroid antibodies, with the prevalence of thyroid antibodies being significantly higher in patients referred to a rheumatology center for an ANA without evidence of connective tissue disease compared to the general population. The purpose of the present study was to determine the frequency of thyroid antibodies in children referred to a pediatric rheumatology center for a positive ANA without evidence of a connective tissue disease. Methods A retrospective chart review was performed on children who were referred to our pediatric rheumatology center between August 2003 and March 2007 for positive ANA with concurrent thyroid antibody and thyroid function tests performed who did not fulfill criteria for a specific connective tissue disease. Laboratory and clinical features were recorded and analyzed. Mean and standard deviation were used to describe continuous data. Chi-square or Fisher's exact tests were used to compare proportions between variables. Results One-hundred and four ANA-positive patients with concurrent thyroid studies were evaluated (88% female, 93% Caucasian, mean age 11.9 ± 4.0 years. Half of patients had an ANA titer ≥ 1:320. The ANA pattern was speckled in 60% of the patients. Thyroid antibodies were detected in 30% of the patients. Anti-Thyroglobulin (ATG was detected in 29% and Anti-thyroid peroxidase (ATPO in 21% of the patients; of these children, 14% had hypothyroidism. ANA pattern and titer were not associated with anti-thyroid antibody positivity. Conclusion Thyroid antibodies associated with chronic lymphocytic thyroiditis, ATG and ATPO, were detected significantly higher in ANA-positive children without a rheumatologic condition (30% as

    Aim: One of the important parts of treatment of Grave's disease with I-131 is the delivery of accurate dose to the target volume. Three important parameters that need to be accurately measured for dosimetry are; the 24 hr thyroid uptake (%), the thyroid mass and effective half life of I-131 in the gland. In this presentation we describe the estimation thyroid mass by SPECT. We have standardised a method to estimated thyroid volume by SPECT using thyroid phantoms of different sizes and then used them for routine thyroid mass estimation in patients with Graves' disease. Materials and Methods: Due to variation in thyroid weight in patients with Grave's disease, we standardised the scintigraphic (SPECT) technique using thyroid phantoms of different volumes such as 5 ml, 9.5 ml, 10.5 ml, 35 ml, 80 ml, 101ml and 110 ml. Each phantom was filled with 99 mTc solution with different activity concentration (100 μCi, 300 μCi, 600 μCi and 1.0 μCi) and SPECT images were acquired on a VARICAM dual head camera in 128x128 matrix. The acquired data was processed using a standardised Metz filter but without attenuation or scatter correction. Coronal slices were used with suitable threshold for edge detection. An irregular ROI was plotted around each lobe and isthmus of the thyroid gland and the enclosed slice area was measured. The area measured from all the frames was added and multiplied by the slice thickness to get the volume of the thyroid gland. The estimated volume of each phantom was compared and correlated with its actual volume. The thyroid mass in 40 patients was estimated by SPECT and compared with that estimated by ultrasonography.Results and Conclusion: The results of thyroid mass estimation with SPECT in phantom study suggested a 30% threshold for all phantom volumes. However, 35% threshold was used in patients' images for estimating thyroid volume. The estimated volumes by scintigraphy were compared with that estimated by ultrasonography.

    The diagnosis of thyroiditis encompasses a broad spectrum of thyroid disorders. Analysis of signs and symptoms, biochemical changes, neck ultrasound characteristics and radioactive iodine uptake values allows an accurate diagnosis. Recent studies of the whole genome have helped to identify many susceptibility genes for autoimmune thyroiditis. However, none of these genes contribute to a significant increase in risk of developing this thyroiditis. Clinical awareness of the characteristic presentations of exceptional thyroiditis (acute suppurative thyroiditis, Riedel's thyroiditis) is an important issue. Selenium administration seems to be beneficial for reducing the incidence of thyroiditis. Finally, certain drug-induced thyroiditis remains a therapeutic challenge for the physician.

    Thyroid function was measured in 119 children, 16 years of age or less, after radiotherapy (XRT) for Hodgkin's disease. Thyroid abnormalities developed in 4 of 24 children (17%) who received 2600 rad or less, and in 74 of 95 children (78%) who received greater than 2600 rad to the cervical area, including the thyroid. The abnormality in all but three (one with hyperthyroidism and two with thyroid nodules) included the development of elevated levels of thyroid stimulating hormone (TSH). Age, sex, and administration of chemotherapy were not significant factors in the development of thyroid dysfunction. All children had lymphangiograms (LAG) and no time relationship was noted between thyroid dysfunction and LAG-XRT interval. The mean interval from radiotherapy to documented thyroid dysfunction was 18 months in the low-dose group and 31 months in the high-dose group, with most patients becoming abnormal within 3 to 5 years. Of interest was a spontaneous return of TSH to within normal limits in 20 children and substantial improvement in another 7. This study confirms the occurrence of dose-related occult hypothyroidism in children following external irradiation of the neck

    Autoimmune thyroid diseases (AITD) show a female predominance, with an increased incidence in the years following parturition. Fetal microchimerism has been suggested to play a role in the pathogenesis of AITD. However, only the presence of fetal microchimeric cells in blood and in the thyroid gland of these patients has been proven, but not an actual active role in AITD. Is fetal microchimerism harmful for the thyroid gland by initiating a Graft versus Host reaction (GvHR) or being the target of a Host versus Graft reaction (HvGR)? Is fetal microchimerism beneficial for the thyroid gland by being a part of tissue repair or are fetal cells just innocent bystanders in the process of autoimmunity? This review explores every hypothesis concerning the role of fetal microchimerism in AITD.

    Objective: To investigate the clinical significance of changes of serum thyroid peroxidase antibody (TPO-Ab) in patients with hyperthyroidism, hypothyroidism and simple goiter. Methods: Serum TPO-Ab, TMA,TGA and FT 3 , FT 4 , TSH levels were measured with radioimmunoassay(RIA) in 69 patients with hyperthyroidism, 53 patients with hypothyroidism, 45 patients with simple goiter and 20 controls. Results: The positive rate of thyroid peroxidase antibody (TPO-Ab) (82%-92.5%) was higher than that of thyroidglobulim antibody(TGA) (44.2%) and thyroid microsome antibody(TMA) (60.4-69.8%) in all patients with AICD. Conclusion: TPO-Ab could be taken as an important indicator in assessment of treatment and prognosis in patients with auto- immune thyroid diseases. (authors)

    Full Text Available Resistance to thyroid hormone (RTH syndrome is a very rare disorder characterized by mutations of the thyroid hormone receptor beta and is usually inherited as an autosomal dominant trait. Patients with RTH are usually euthyroid but rarely may present with signs and symptoms consistent with hyperthyroidism. Here, we describe the case of a young girl with goiter who was previously misdiagnosed to have hyperthyroidism and was subsequently diagnosed to be suffering from RTH.

  2. Is selenium supplementation in autoimmune thyroid diseases justified?

    2017-10-01

    This review provides an appraisal of recent evidence for or against selenium supplementation in patients with autoimmune thyroid diseases, and discusses possible effect mechanisms. Epidemiological data suggest an increased prevalence of autoimmune thyroid diseases under conditions of low dietary selenium intake. Two systematic reviews have evaluated controlled trials among patients with autoimmune thyroiditis and report that selenium supplementation decreases circulating thyroid autoantibodies. The immunomodulatory effects of selenium might involve reducing proinflammatory cytokine release. However, clinically relevant effects of selenium supplementation, including improvement in quality of life, are more elusive. In Graves' disease, some, but not all, trials indicate that adjuvant selenium supplementation enhances the restoration of biochemical euthyroidism, and might benefit patients with mild Graves' orbitopathy. The use of selenium supplementation as adjuvant therapy to standard thyroid medication may be widespread, but a growing body of evidence yields equivocal results. The available evidence from trials does not support routine selenium supplementation in the standard treatment of patients with autoimmune thyroiditis or Graves' disease. However, correction of moderate to severe selenium deficiency may offer benefits in preventing, as well as treating, these disorders. Molecular mechanisms have been proposed, but further studies are needed.

    Objective: Graves’ disease and Hashimoto’s thyroiditis are the most common causes of hyper and hypothyroidism, respectively. Differentiation of these 2 diseases, if the patient is euthyroid, may sometimes be extremely difficult on the basis of clinical and laboratory findings. The purpose of this study was to determine the sensitivity and specificity of gray scale sonography in differentiation of Graves’ disease from Hashimoto’s thyroiditis. Methods: This study included 149 patients divided into three groups, patients with Graves’ disease (34 patients, mean age = 36.8 ± 10.17 years), Patients with Hashimoto’s thyroiditis (62 patients, mean age = 33.4 ± 12.16 years) and control group (53 healthy people, mean age = 34.74 ± 16.87 years). Members of all groups were referred to a single radiologist for thyroid sonography for evaluation of thyroid echogenicity pattern. Results: A total of 117 women and 32 men were examined by sonography. The most common sonographic pattern in Hashimoto and Graves’ was homogenous hypo-echogenicity which was observed in 45.2% and 47.1% of cases, respectively. Peripheral hypo-echogenicity pattern was seen in 40.3% of Hashimoto’s group with 100% specificity and 40.3% sensitivity. Central-hypoechogenic pattern was observed in 17.6% of Graves’ group with 100% and 17.6% specificity and sensitivity, respectively. Conclusion: Our findings indicate that sonography has high specificity but low sensitivity in the diagnosis of either Graves’ disease or Hashimoto’s thyroiditis. It is therefore not possible to differentiate between these two diseases using sonography alone. Confirmation by laboratory data is also needed. PMID:28451576

With these markers we identified a large subgroup in the general population with a substantially increased risk of TPOAbs. The results provide insight into why individuals with thyroid autoimmunity do or do not eventually develop thyroid disease, and these markers may therefore predict which TPOAb-positives are particularly at risk of developing clinical thyroid dysfunction.

    Patients with autoimmune thyroid diseases (ATD) such as Graves' disease (GD) and Hashimoto thyroiditis (HT) may have non-organ specific autoantibodies such as ANA (antinuclear antibodies) and RF (rheumatoid factor). To study the prevalence of rheumatic autoantibodies in a group of ATD patients without known rheumatic diseases and to evaluate its association with the patients' epidemiological and treatment profile. To follow positive non-organ specific autoantibody-positive ATD individuals to investigate whether they will develop a rheumatic disorder. A sample of 154 ATD patients (70 HT and 84 GD; mean age 45.3 ± 14.2) had determination of ANA by immunofluorescence, using hep-2 cells as substrate, extractable nuclear antigen (ENA) profile by ELISA kits and RF by latex agglutination. Epidemiological and treatment profile were obtained through chart review. These patients were followed for the mean period of five years, between 2010 to 2015. Positive ANA was found in 17.5% (27/154) of the patients: anti-Ro/SS-A in 4/154 (2.5%); anti-RNP in 4/154 (2.5%) and anti-La/SS-B in 3/154 (1.9%). None had anti-Sm antibodies. RF was detected in 12/154 (7.7%) of ATD patients and was more common in older individuals (p = 0.007). There was a positive association between the presence of RF and ANA (p = 0.03; OR = 3.89; 95% CI = 1.1-13.3). None of the patients with positive autoantibodies developed clinical rheumatic diseases during the period of observation. We found rheumatic autoantibodies in 17.5% of ATD patients without rheumatic diseases. None of them were associated with the appearance of clinical rheumatic disorder during the period of five years. ©2018The Author(s). Published by S. Karger AG, Basel.

    We evaluated the differences in diagnosis and treatment for primary hyperparathyroidism (pHPT) in patients with and those without concomitant thyroid disease. One hundred and ten patients with pHPT underwent parathyroid localization and thyroid examination by ultrasonography (US) and sestamibi scintigraphy (MIBI). The clinical and biochemical findings, parathyroid localization, and operations performed were compared in 49 patients without thyroid disease and 61 patients with thyroid disease. Asymptomatic hypercalcemia was significantly more prevalent in patients with concomitant thyroid disease (88.5%) than in those without thyroid disease (49.0%) (P<0.01). The mean serum calcium was significantly higher and the inorganic phosphate level was significantly lower in patients without concomitant thyroid disease than in those with concomitant thyroid disease (P<0.05, P<0.01, respectively). The pathologic parathyroid gland was identified significantly more often in patients without concomitant thyroid disease than in those with concomitant thyroid disease both by US and MIBI (P<0.05). Unilateral exploration was performed more often in patients without thyroid disease than in those with thyroid disease (P<0.01). Primary hyperparathyroidism was diagnosed at an earlier stage in patients with concomitant thyroid disease. Thyroid disease concomitant with pHPT influenced parathyroid localization as well as the indication for minimally invasive parathyroidectomy. (author)

    In recent with development of immuno-electrophoresis, more accurate analysis of the serum protein became possible. However, there is few reports in the literature which investigated the changes of the immunoglobulin compared with electrophoretically fractioned serum thyroglobulin in the patients with various thyroid diseases. The purpose of this report is to investigate the changes of thyroglobulin in various thyroid diseases by the method of immuno-electrophoresis and to compare the results with serum protein fractionated by the method of agar-gel micro-electrophoresis. Sera from 9 patients with diffuse toxic goiter, 2 nodular nontoxic goiter, 2 thyroiditis, 3 hypothyroidism, 1 thyroid cancer, 7 cystic degeneration of the thyroid gland, and 10 normal subject were taken. All cases were confirmed by various laboratory thyroid function tests and thyroid needle biopsy. Immuno-electrophoretic analysis of the serum were performed by Scheidegger's modified micro-immuno-electrophoretic method. The antiserum was obtained from the Travenol Laboratories International, Hyland Products Division and was rabbit anti-human thyroglobulin. Microscope slide agar-gel electrophoresis for serum protein fractionation was performed at 4 .deg. C using veronal buffer, pH 8.6 and ionic strength 0.05, with 54 volts and 2.8 mA for 60 minutes. The fractionated slide was stained with 0.1% thiazine red. The results were as follows: 1) Increase of immune-globulin macroglobulin (IgM), alphaglobulin, and immune-globulin A (IgA) by 95.8%, 100%, 29.2% respectively was found in the serum from various thyroid diseases. 2) Thyroglobulin fraction was found to be increased in 50%, no change in 41.7%, and no line in 8.3% with all of the various goiter patients. On the other hand, 10 normal control group showed only 2 cases of increase, 5 cases of no change and 3 cases of no line.

    The aim of this study was to evaluate clinical and laboratory findings and determine the prevalence of celiac disease (CD) in children with Hashimoto thyroiditis (HT). The data of a total of 80 patients with positive anti-thyroid antibodies who were aged between 6 and 17.9 years were retrospectively studied. Age, gender, complaints at the time of presentation, family history of thyroid disorders, clinical and laboratory findings were recorded. The levels of thyrotropin, free thyroxin, thyroid autoantibodies (thyroid peroxidase and thyroglobulin antibodies), immunoglobulin A (IgA), anti-tissue transglutaminase antibodies (IgA-tTG), and thyroid ultrasonography findings were enrolled. Eighty patients (65 females (81.2%) and 15 males (18,8%)) were included in the study. Family history of thyroid disease was present in 38 (47.5%) patients. The most common complaints at the time of presentation were goiter (%30) and weight gain (%25). Forty three (53.8%), 23 (28.7%), and 14 (17.5%) patients presented with euthyroidism, subclinical hypothyroidism and obvious hypothyroidism. Thirty seven (46.2%) patients had goiter. IgA-tTG was found to be positive after a diagnosis of HT was made in only one patient (1.25%) and the diagnosis of CD was confirmed when intestinal biopsy of this patient revealed villus atrophy, crypt hyperplasia and increase in the intraepithelial lymphocyte count. In our study, it was found that the most common complaints at presentation in patients with a diagnosis of hashimoto thyroiditis included goiter, weakness and weight gain and the prevalence of celiac diseases was found to be 1.25% (1/80). This study shows that the prevalence of CD in patients with a diagnosis of HT is higher compared to the prevalence in the healthy pediatric population.

    Primary squamous cell carcinoma (SCC) of the thyroid gland is extremely rare. Infrequently, primary SCC of the thyroid gland is accompanied by other thyroid diseases such as Hashimoto's thyroiditis (HT). Recently, studies have demonstrated that differentiated thyroid cancer with coexisting HT has a better prognosis. However, the prognosis of patients with primary SCC of the thyroid gland and coexistent HT has not been clearly identified. We compared the clinical characteristics and disease stages of patients with primary SCC with and without lymphocytic thyroiditis (LT). We reviewed reports of primary SCC of the thyroid gland published in the English literature. We identified 46 papers that included 17 cases of primary SCC of the thyroid gland with LT and 77 cases of primary SCC of the thyroid gland without LT. Lymph node metastasis and local invasion rates did not differ between these two groups. Distant metastases were absent in patients with LT, and were observed in 13 (16.9%) patients without LT. A greater proportion of patients without LT had advanced stage disease (stage IV A-B-C) than patients with LT (p thyroid gland and coexisting LT had lower tumour-node-metastasis stage and frequency of distant metastasis than those without LT. Lymphocytic infiltration in patients with SCC appears to limit tumour growth and distant metastases.

    Full Text Available Introduction. Plasma antithyroid peroxidase (anti-TPO and anti-thyroglobulin antibodies (anti-Tg are widely used in the diagnosis of autoimmune thyroiditis. No research has compared anti-TPO and anti-Tg both in plasma and cerebrospinal fluid (CSF of healthy individuals vis-à-vis patients with thyroid disease. Methods. We measured anti-TPO and anti-Tg antibodies in plasma and CSF in nine subjects (mean age ± SD: 73 ± 6 years with hypothyroidism and nine subjects (mean age ± SD: 73 ± 8 years without thyroid disease. Results. The concentration of anti-TPO autoantibodies in CSF was very low compared to plasma in both subjects with thyroid and without thyroid disease (P=0.007. CSF anti-Tg autoantibodies titers were very low compared to the plasma in subjects with thyroid disease (P=0.004, whereas, in subjects without thyroid disease, this difference did not reach statistical significance (P=0.063. Conclusions. Thyroid autoantibodies levels were low in plasma and CSF; we did not observe any transfer of thyroid autoantibodies from the peripheral blood to the CSF. Therefore, regarding Hashimoto’s encephalopathy, where elevated antithyroid autoantibodies are often measured in blood, it is more likely that thyroiditis and encephalopathy represent nonspecific, but distinct, events of an aggressive immune system.

    The skin is the largest organ of the body and it protects against heat, light, injury and infection. Skin temperature is an important parameter for diagnosing diseases. Thermal analysis is non-invasive, painless, and relatively inexpensive, showing a great potential research. Since the thyroid regulates metabolic rate it is intimately connected to body temperature, more than, any modification of its function generates a specific thermal image on the neck skin. The shapes of thermal signatures are often irregular in size and shape. Euclidean geometry is not able to evaluate their shape for different thyroid diseases, and fractal geometry is used in this paper. Different thyroid diseases generate different shapes, and their complexity are evaluated by specific mathematical approaches, fractal analysis, in order to the evaluate selfsimilarity and lacunarity. Two kinds of thyroid diseases, hyperthyroidism and papillary cancer are analyzed in this paper. The results are encouraging and show the ability to continue research for thermal signature to be used in early diagnosis of thyroid diseases.

    Multinodular goitre is one of the commonest thyroid diseases encountered in the practice of surgery. The most common surgery being performed for multinodular goitre is subtotal thyroidectomy. Total thyroidectomy is designed to remove all of the thyroid tissue. The objective of this study was to evaluate total thyroidectomy as a primary elective procedure for treatment of multinodular thyroid disease. This descriptive study was carried out at Combined Military Hospital Rawalpindi from June 2003 to September 2006. 88 patients of multinodular thyroid disease were included. Patients having evidence of recurrent laryngeal nerve damage, recurrent goitre, evidence of altered parathyroid functions or evidence of malignancy were excluded. All patients underwent total thyroidectomy by the same team of surgeons and the patients were closely followed up for postoperative complications especially in terms of recurrent laryngeal nerve damage and hypocalcaemic tetany. No major postoperative complication was noted. Only 1 patient (1.14%) developed unilateral recurrent laryngeal nerve damage and 2 patients (2.27%) developed transient hypocalcaemia that recovered quickly. Total thyroidectomy as a primary elective procedure in multinodular thyroid disease is a safe option and it removes the disease process completely, lowers local recurrence rates and avoids the substantial risks of re operative surgery.

    Hypothyroidism in patients with Graves\\' disease is usually the result of ablative treatment. We describe a 58 year old man with Graves\\' ophthalmopathy and pre-tibial myxoedema, who presented with spontaneous primary hypothyroidism. Circulating TSH receptor antibody activity was increased, while thyroid microsomal antibody was detectable in titres greater than one in one hundred thousand. It is likely that the TSH receptor antibody of Graves\\' disease was ineffective in stimulating hyperthyroidism because of concomitant thyroid destruction due to Hashimoto\\'s disease. Alternatively, primary hypothyroidism could have resulted from the effects of a circulating TSH receptor blocking antibody.

    In 1912 Japanese physician Hashimoto Hakaru described 4 patients with chronic thyroid disease. The histopathology findings exactly 100 years ago described lymphocyte infiltration, fibrosis, parenchymal atrophy and eosinophilic changes of some acinar cells. Those findings are typical for the autoimmune thyroid disease named by the author Hashimoto thyroiditis or lymphocytic thyroiditis. Hashimoto thyroiditis: The pathophysiology of thyroid autoimmunity during the past decades was described in details. Many thyroid antigens were identified (thyroid - stimulating hormone or TSH, thyroglobulin, thyreoperoxidase) and antibodies are directed towards them. Thyreocyte is also able to function as antigen presenting cell. It presents antigen on its surface and expresses MHC class II and class I molecules. Etiology of autoimmune thyroiditis combines genetic and environmental factors. Genetic factors dominate, and influence with about 80% on the occurrence of immunity. Some HLA genes (HLA-DR3, HLA-DR4, HLA-DR5 and HLA-DQA) and some non-HLA genes (cytotoxic T-lymphocyte antigen 4 -CTLA-4, CD40 gene, gene for protein tyrosine phosphatase 22 -PTPN22, thyroglobulin and TSH gene) are involved. 20% of etiology is attributed to environmental factors (smoking, iodine intake, selenium deficiency, pollution, infectious conditions, physical and emotional stress) and physiological states (puberty, rapid growth, pregnancy, menopause, aging, female gender). Although Hashimoto thyroiditis is known for many years, it is still sometimes presented with surprisingly diverse clinical entities and frequently astonishes many physicians. A case of a female patient with long-standing hypothesis (fine needle aspiration showed lymphocytic infiltration, thyreoperoxidase antibodies were positive) is presented. During the postpartum period, complicated with septic endometritis a new onset of hyperthyreosis appeared. The etiology of hyperthyroidism was unclear, with three possible explanations. The first

    The TRAb content of the thyroid diseases 758 cases (including the first visit thyroidism group 166 cases; the thyroidism group with normal thyroid function by medicine treatment 198 cases, the group with abnormal thyroid function by medicine treatment 86 cases, the group with lower thyroid function 24 cases, the group with normal thyroid function by 131 I treatment 104 cases, the subacute thyroiditis group 48 cases, the simple goiter group 52 cases, the primary hypothyroidism group 80 cases) and the normal control group 62 cases are detected. The results show that the values of TRAb are much higher in the groups with normal or abnormal thyroid function by medicine treatment, the group with lower thyroid function, the group with 131 I treatment and the group with primary hypothyroidism than that of control group (P 0.05). The differential of the TRAb average and positive rate is obvious between the groups with normal and abnormal thyroid function by medicine treatment (P 131 I treatment (P < 0.01). The TRAb levels in serum are higher in the patients with thyroidism and primary hypo-thyroidism, and the TRAb levels are normal in the patients with subacute thyroiditis and simple goiter. So, TRAb is a auxiliary index in the diagnosis of thyroidism and hypo-thyroidism and also a differential diagnosis index about the thyroidism and subacute thyroiditis. At the same time, TRAb is an important index in evaluating the autoimmune monitoring function of the body, and stopping the use of thyroid medicine

    The authors analyzed ultrasonographically the total 45 cases of thyroid disease verified by historical diagnosis, functional diagnosis, and morphological diagnosis at the Department of Radiology, Busan National University Hospital from June to September 1982. The results obtained were as follows: 1. In the sex distribution female was 38 cases (84.4%), and male 7 cases (15.6%). The second, third, and fourth decades of age (78.0%) were most prevalent. 2. Among the total 45 cases thyroid adenoma was 24 cases (53.3%), nodular hyperplasia cases (17.7%), thyroid carcinoma 7 cases (15.6%), diffuse hyperplsia 3 cases (6.7%), Hashimoto's thyroiditis 1 cases (2.2%), subacute thyroiditis 1 cases (2.2%), tuberculous thyroiditis 1 case (2.2%) in orders. 3. On ultrasonogram, total 24 cases of thyroid adenoma showed a single nodule in 24 cases (100.0%), smooth outer margin in 23 cases (95.8%), capsular echo in 23 cases (95.8%), pure cystic nodule in 4 cases (16.7%), and increased echogenicity in 17 cases (85.0%) among the 20 cases exclude that pure cystic nodules. 4. Total 7 cases of thyroid carcinoma showed no capsular echo in 4 cases (57.1%), irregular outer margin in 4 case (57.1%), no pure cystic nodule in all cases, and enlargement of metastatic lymphnode in 4 cases (57.1%). 5. Total 8 cases of nodular hyperplasia showed enlargement of thyroid gland and multiple nodule in 8 cases (100.0%), and increased echogenicity in 7 cases (87.5%). 6. Total 3 cases of diffuse hyperplasia showed enlargement of thyroid gland and increased echogenicity in 3 cases (100.0%). 7. Total 3 cases of thyroiditis showed decreased echogenicity in 3 cases (100.0%) and enlargement of thyroid gland in 2 cases (66.7%). 8. The cold area visualized on radionuclide scan could be differentiated from a solid mass and cystic one by ultrasonogram.

    Immune thrombocytopenia (ITP) is an entity characterized by a platelet count of less than 100 × 10(9)/L in the absence of other causes of thrombocytopenia, such as viral infections, rheumatic diseases, or drugs. Grave's disease is also an autoimmune condition in which thrombocytopenia is often observed. Moreover, in the literature, many reports show a marked interference of the thyroid dysfunction (mainly hyperthyroidism) in the control of thrombocytopenia. Although this issue still remains debatable, the authors report the case of a young woman with a previous diagnosis of ITP with a brilliant initial response to corticotherapy. Some years after this diagnosis, the patient presented thyrotoxicosis due to Grave's disease and the thrombocytopenia relapsed, but this time there was no response to the glucocorticoids. Only after the radioiodine I-131 thyroid ablation the control of thrombocytopenia was achieved. The authors call attention to this overlap and for testing thyroid function in every patient with an unexpected negative response to corticotherapy.

    Currently there is a growing interest in studying systemic conditions with impact on the periodontium. The aim of this article is to determinate if there is a relation between Hashimoto's thyroiditis and periodontal disease. Founded on periodontology based on evidence and in the combination of the keywords: 'Hashimoto disease'; 'Hypothyroidism'; 'Periodontal disease'; 'Systemic Diseases'; a search and evaluation of articles was conducted in Medline, Scopus and Thomson Reuters databases, selecting 30 articles for integral analysis. There have been developed several studies, searching for a better comprehension about the complexity and pathogenesis of periodontal diseases, associated them to multiple systemic conditions. Actually, the relationship that is best described in the literature is the one with rheumatoid arthritis; however, other relations have been pointed, such as Hashimoto's thyroiditis. The identification of multiple etiopathogenic mechanisms common to Hashimoto's thyroiditis and periodontal disease allow to suspect of a relation between them. Some of these mechanisms include the proliferation of lymphocytes T helper 1 and T helper 17 and their impact on the periodontium, the dysfunction of vascular endothelium in gingival microcirculation and the influence of hypothyroidism on bone metabolism, namely on the alveolar bone. There is biological plausibility to support the establishment of an association between Hashimoto's thyroiditis and periodontal disease. However, there are not enough studies to support the existence of a causal nexus between these two pathologies, so, in the future, more studies should be conducted to determinate there relation and interaction.

    In 1954, 253 Marshallese were accidentally exposed to fallout radiation from the hydrogen bomb, BRAVO. The Marshall Islands Medical Program (MIMP) was established by the Department of Energy in 1955 to monitor and treat radiation-related disease pursuant to this accident. Medical teams from Brookhaven National laboratory, a federal institution, regularly visit the Marshall Islands to give medical care to the exposed population. The most significant complication of the exposure has been found to be thyroid disease due to the ingestion of radioactive iodides from the fallout. In 1963 the first thyroid nodules were found in Rongelap subjects and in 1969 in Utirik. Non-neoplastic adenomatous nodules were associated with higher doses of radiation and neoplastic nodules developed in individuals receiving lower doses of radiation. Women were more susceptible to the development of palpable thyroid nodules than men. In 1994 the MIMP initiated examination of the thyroid by ultrasound to supplement the clinical examination. One hundred and sixty-four patients were evaluated. No significant differences were found in the incidence of thyroid nodules or the mean nodule count between the three groups of Rongelap and Utirik exposed and a comparison patient population. There was no significant difference in the incidence of thyroid nodules in males vs. females. Five exposed patients were referred for surgical excision of a nodule detected only by ultrasound. These ultrasound findings are unexpected in that females are known to have a higher incidence of thyroid disease than males and we expected that the incidence of ultrasound nodules would be higher in the exposed population. 36 refs., 2 figs., 8 tabs

    Full Text Available Type I diabetes mellitus (DM is frequently associated with autoimmune thyroid disease (ATD. Association of ATD and type I DM has been described with varying frequencies but there is still debate about the situation in the Iranian population. We investigated the prevalence of anti thyroid peroxidase (anti-TPO antibodies and ATD in children and adolescents with type I DM. A total of 145 patients with type I DM were participated in this study. They were screened for anti-TPO antibodies and TSH levels. Signs and symptoms of hypothyroidism and hyperthyroidism and the presence of goiter were sought. A group of 50 healthy unrelated girls and boys aged 11-16 years served as controls. Anti-TPO antibodies were found in 34 (23.4% diabetic patients and 1 subject (2% in the control group (P<0.001. Frequency of anti TPO antibodies was significantly higher in girls than boys (P<0.05. We failed to show any significant correlation between thyroid autoimmunity and duration of DM. We found that younger patients at diagnosis are more likely to be anti-TPO negative (P<0.001. Out of 145 diabetic patients, 32 (22% had visible goiter. Subclinical hypothyroidism, hypothyroidism and thyrotoxicosis occurred in 1, 9 and 1 patients, respectively. Visible goiter was found in 2 subjects (4% of the control group, but all of them were euthyroid. In conclusion, the evaluation of thyroid autoimmunity in type I diabetic patients may improve the diagnosis of thyroid disease in early stages. Yearly examination of anti-TPO antibodies allows identifying diabetic patients with thyroid autoimmunity.

    Kinetics of the thyroid pertechnetate trap were assessed in 39 normal subjects, five untreated patients with Graves' disease (two before and after treatment), two hypothyroid patients, and in one patient each with Hashimoto's thyroiditis of recent onset, subacute thyroiditis, and massive anaplastic carcinoma. In normal subjects, the effects of sex, time of day, and order of experimental sessions were studied. A three-compartment model was assumed for all studies. Data on thyroidal and neck-background pertechnetate were collected with a multicrystal camera during 40 min after iv injection. The two thyroidal compartments in the model - the follicular cell, v/sub 2/, and the colloidal plasma-equivalent space, V/sub 3/ - is a multi-exponential function of plasma radioactivity, V/sub 1/. None of the model parameters was systematically affected by sex and order of session did not consistently alter any parameter, except for V/sub 3/, which was greater in session 2 than in session 1. That increase was not consistent and is believed to be spurious. Time of day affected only the exit rate constant from the colloid ..lambda../sub 23/, which was increased later in the day (P < 0.02). Distribution of the normal parameters was more log-normal than normal. After 5% were excluded at the high end and at the low end, the range for a parameter, p, was found empirically to be: antiln (mean ln p - 1.7 s.d. ln p), and antiln (mean ln p + 1.5 s.d. ln p). In Graves' disease, V/sub 2/ is increased (P < 0.02), but the increases in V/sub 3/ and in ..lambda../sub 21/ (the clearance into the thyroid from serum) are more dramatic (P < 10/sup -8/). After treatment, V/sub 3/ and ..lambda../sub 21/ fell toward normal. The hypothyroid patients showed no trap activity, and the trap was normal in the patient with early Hashimoto's thyroiditis. The patients with subacute thyroiditis and anaplastic carcinoma had increases in V/sub 2/, V/sub 3/, and ..lambda../sub 21/, but the

    The thyroid nodular disease is defined by the presence of nodules of thyroid of solid, liquid or mixed consistency, they are or non concrete. Solitary nodule thyroid, diffuse and multinodular goiter forms can be presented in. The thyroid nodule is a frequent clinical problem, the clinical prevalence in adult population is of 4%. Objective: to make a bibliographical revision to near the utility of the different methods available for the thyroid nodular pathology diagnosis and determining which of them turns out more specific to differentiate benignancy from malignancy in the found nodules. Materials and Methods: the bibliographical search was made in the data base Medline (Pubmed), in scientific magazines of the region and text books. Criteria of inclusion: bibliographical references pertaining to medical magazines and free full text with an antiquity nongreater to 8 years were included. Conclusion: the presence of thyroid nodules constitutes a reason for frequent consultation, the main diagnostic method at the moment is the fine needle aspiration cytology, due to its simple accomplishment, low cost, not requiring the hospitalization of the patient, and being fundamental in the decision making of the doctor. This diagnostic method is, in addition, the one that with greater certainty allows to differentiate benign from malignant nodules. (authors) [es

    Thyroid function was studied in 46 long-term survivors of pediatric Hodgkin's disease with a median follow-up time of 10.5 years. The mean age of the patients at the time of treatment was 8 years. Treatment consisted of radiotherapy alone in seven patients and combined radiation and chemotherapy in 39 patients. The radiotherapy dose to the thyroid gland was less than 2000 cGy in one, 2000-5000 cGy in 15, 2500-3000 cGy in 17, and greater than 3000 cGy in 13 patients. Evaluation consisted of clinical examination and thyroid function tests of total and free triiodothyronine, thyroxin, arid thyroid stimulating hormone levels. Twenty-one of 46 patients (45.6%) showed thyroid function abnormalities, however only nine of them had diffuse or nodular hyperplasia on physical examination. Risk factors of age, chemotherapy schema, total radiation dose, and dose per fraction did not significantly influence the incidence of thyroid dysfunction. (author)

    Full Text Available Recently, thyroid diseases are more and more spread worldwide. In Romania, for example, one of eight women suffer from hypothyroidism, hyperthyroidism or thyroid cancer. Various research studies estimate that about 30% of Romanians are diagnosed with endemic goiter. The factors that affect the thyroid function are: stress, infection, trauma, toxins, low-calorie diet, certain medication etc. It is very important to prevent such diseases rather than cure them, because the majority of treatments consist in long term medication or in chirurgical intervention. The current study refers to the thyroid disease classification in two of the most common thyroid dysfunctions (hyperthyroidism and hypothyroidism among the population. The authors analyzed and compared four classification models: Naive Bayes, Decision Tree, Multilayer Perceptron and Radial Basis Function Network. The results indicate a significant accuracy for all the classification models mentioned above, the best classification rate being that of the Decision Tree model. The data set used to build and to validate the classifier was provided by the UCI machine learning repository and by a website with Romanian data. The framework for building and testing the classification models was KNIME Analytics Platform and Weka, two data mining software.

    Recently hyperparathyroidism associated with some thyroid diseases, especially nonmedually thyroid carcinoma has been payed attention to. In this study we analyzed 12 cases of hyperparathyroidism (6 cases independent of thyroid diseases and 6 cases associated with thyroid diseases) and estimated the affect of association with thyroid diseases on the preoperative localization of the parathyroid glands. The results of preoperative localization of the parathyroid glands in cases independent of thyroid diseases were relatively satisfactory. On the other hand, the preoperative localization in cases associated with thyroid diseases came to false result in about half of them. It was far from satisfactory. Association of thyroid diseases strongly affected the preoperative localization of the parathyroid glands in hyperparathyroidism. Conventional imaging such as ultrasonography, CT, MRI and 201 Tl- 99m TC subtraction scintigraphy alone were not satisfactory. Now 99m Tc-MIBI scintigraphy is expected to be one of reliable imaging methods for progress in the preoperative localization. (author)

    The present study describes in depth a case of Riedel thyroiditis (RT) to clarify its pathogenesis and its putative inclusion in the spectrum of IgG4-related disease. We report the clinicopathological, immunohistochemical, and ultrastructural features of a case of RT in a 39-year-old white Spanish woman, admitted with a hard goiter and cold nodule in the left thyroid lobe. This case represents 0.05 % of a series of 1,973 consecutive thyroidectomies performed in our hospital. More than 80 % of the left thyroid lobe was effaced by fibrosis and inflammation (lymphocytes, 57 IgG4+ plasma cells per 1 high-power field, an IgG4/IgG ratio of 0.67, and eosinophils) with extension into the surrounding tissues and occlusive phlebitis. Immunostaining for podoplanin (D2-40) detected signs of increased lymphangiogenesis in the fibroinflammatory areas that were confirmed by electron microscopy. A strong, diffuse stain for podoplanin and transforming growth factor ß1 was also detected in the same areas. The increased number of lymphatic vessels in RT is reported for the first time. Our findings support the inclusion of RT within the spectrum of IgG4-related thyroid disease (IgG4-RTD). Although the etiology and physiopathology of IgG4-RTD still remain elusive, the results obtained in the present case suggest the participation of lymphatic vessels in the pathogenesis of RT.

Due to the rarity of this disease, only a limited number of studies and case reports are available for further evaluation of the characteristics of the disease. The aim of this study was to examine the changes in the thyroid function, thyrotropin receptor antibodies (TRAb and eye symptoms, and then determine whether TRAb is related to TAO in EGD patients. TRAb in this study was defined as including both thyrotropin-binding inhibitory immunoglobulin (TBII and thyroid-stimulating immunoglobulin (TSAb. Patients and methods: Medical records of patients diagnosed with EGD were reviewed. Ophthalmologists specializing in TAO examined the eyes of all subjects. Results: Of the 58 patients diagnosed with EGD, 24.1% developed hyperthyroidism, while 3.4% developed hypothyroidism. A total of 72.4% of the 58 patients remained euthyroid throughout the entire follow-up period. At the initial presentation, TBII and TSAb were positive in 74.5% and 70.5%, respectively. Ophthalmic treatments were administered to 30 (51.7% out of the 58 patients. A significant spontaneous improvement of the eye symptoms was found in 28 of the EGD patients who did not require eye treatments. EGD patients exhibited positive rates for both TBII and TSAb, with the number of the TRAb-positive patients gradually decreasing while the eye symptoms spontaneously improved over time. There were no correlations found between TRAb at initial presentation and the eye symptoms

    Autoimmune thyroid disease (AITD), including Graves' disease (GD) and Hashimoto's thyroiditis (HT), is one of the most common of the immune-mediated diseases. To further investigate the genetic determinants of AITD, we conducted an association study using a custom-made single-nucleotide polymorphism (SNP) array, the ImmunoChip. The SNP array contains all known and genotype-able SNPs across 186 distinct susceptibility loci associated with one or more immune-mediated diseases. After stringent quality control, we analysed 103 875 common SNPs (minor allele frequency >0.05) in 2285 GD and 462 HT patients and 9364 controls. We found evidence for seven new AITD risk loci (P test derived significance threshold), five at locations previously associated and two at locations awaiting confirmation, with other immune-mediated diseases.

    Steroid replacement without thyroxine supplementation normalizes thyroid function test (TFT) in some but not all Addison's disease patients with primary hypothyroidism. Both autoimmune and nonautoimmune mechanisms contribute to this improvement in TFT. However, the documentation of the change in thyroid autoimmunity after cortisol replacement is very limited in the literature. The aim of this study was to determine the effect of steroid replacement on TFT and anti-thyroid peroxidase antibody (anti-TPO-Ab) titer in Addison's disease with primary hypothyroidism. This observational study was conducted in a tertiary care center in South India. Six Addison's disease patients with primary hypothyroidism, who were only on steroid replacement, were included in the study. Low serum cortisol (22 pmol/L) and/or hyperpigmentation of skin/mucous membranes was considered as the diagnostic criteria for Addison's disease. Primary hypothyroidism (both overt and subclinical) was defined as high thyroid stimulating hormone (TSH) with/without low free thyroxine (fT4). TFT and anti-TPO-Ab were performed before and after steroid replacement in all of them. Poststeroid replacement, there was a normalization of TSH in all but one subjects. In overt hypothyroidism patients, fT4 also normalized. The improvement in TFT was not associated with decreasing titer of the anti-TPO-Ab in all six patients. However, there was a significant difference in TSH after steroid replacement compared to the baseline status. The concept of normalization of primary hypothyroidism with cortisol replacement in patients with Addison's disease should be recognized to avoid iatrogenic thyrotoxicosis caused by thyroxine replacement. Both autoimmune and nonautoimmune mechanisms contribute to these alterations.

    Vitiligo is an acquired dermatological disease frequently associated with autoimmune thyroid disorders. Several theories have been proposed so far to unravel the complex vitiligo pathogenesis. Currently, the autocytotoxic and the autoimmune theories are the most accredited hypothesis, since they are sustained by several important clinical and experimental evidences. A growing body of evidences shows that autoimmunity and oxidative stress strictly interact to finally determine melanocyte loss. In this scenario, associated thyroid autoimmunity might play an active and important role in triggering and maintaining the depigmentation process of vitiligo. PMID:25838868

    Immunoglobulin G4-related disease (IgG4-RD) is an emerging clinicopathologic entity characterized by both IgG4+ plasma cell infiltration and fibrosis in one or more organs, prototypically pancreas or salivary/lacrimal glands. IgG4-RD in the thyroid (IgG4-RTD) is an area of active study, and the relationship between IgG4-RTD and Hashimoto thyroiditis is not fully delineated due to their overlapping histologic features. Retrospective review was performed of all thyroidectomy cases demonstrating lymphocytic inflammation at a single institution over a 4-year period. Approximately half (23/38) of patients had a clinical diagnosis of Hashimoto thyroiditis (HT). Nine of the 38 patients had increased absolute and relative numbers of IgG4+ plasma cells. Patients with a clinical diagnosis of HT had increased lymphoplasmacytic inflammation, but the relative proportion of IgG4+ plasma cells was not increased compared to patients without HT. There was no correlation between IgG4 levels and the amount of fibrosis in patients with or without HT. Patients identified as having the fibrosing variant of HT were not more likely to have increased levels of IgG4+ plasma cells than those without. There is significant morphologic and immunohistochemical overlap between HT and IgG4-RTD. Future studies to identify specific characteristics of IgG4-RTD involving the thyroid are necessary to accurately define this entity.

    Full text: Introduction: Hyperthyroidism is an autoimmune disease in the pathogenesis of which a key role play the antibodies against the thyroid stimulating hormone receptor (TRAb). The aim of this study is to analyze the immune and hormonal status in patients with Graves' disease, who are on thyreostatic therapy and in remission. Materials and methods: 67 patients were studied - 11 men and 56 women - with Graves' disease, mean age 49.7 years (range - 20-76 ). Of these, 55 were on thyreostatic therapy (two subgroups: 27 - treated up to 24 months , and 28 with relapsed disease ) and 12 were in remission up to a year. Patient's condition is assessed as a complex of clinical, biochemical, including hormonal, immune status and ultrasonography of the thyroid gland. We examined thyroid stimulating hormone, free thyroxine, free triiodothyronine, antityreoperoxidase antibodies (Anti-TPO) and TRAb. The patients on therapy are: in hyperthyroidism - 10/ 14 with subclinical hyperthyroidism - 9/8, euthyroid - 7/6 and with subclinical hypothyroidism - 1/0. Results: The patients with hyperthyroidism ( 43.6% ) in both thyreostatic therapy groups have a significantly higher average values of TRAb. The patients with subclinical hyperthyroidism and relapse showed higher levels of TRAb in comparison with those undergoing therapy to 24 months after diagnosing. The values of TRAb in the euthyroid patients in both groups of treatment were 1,5 IU / l. The Anti-TPO values were increased in 78.2% of the patients on therapy and 55.5% of those in remission. Conclusion: With the decrease of thyroid hormones during treatment of Hyperthyroidism the levels of TRAb and Anti-TPO decrease. The TRAb values are useful for the monitoring the effect of the thyreostatic treatment, determining the therapeutic approach in patients with a sustained reduction of TRAb in the course thyreostatic therapy and particularly for relapse

    Immune thrombocytopenia (ITP) is an entity characterized by a platelet count of less than 100 × 109/L in the absence of other causes of thrombocytopenia, such as viral infections, rheumatic diseases, or drugs. Grave’s disease is also an autoimmune condition in which thrombocytopenia is often observed. Moreover, in the literature, many reports show a marked interference of the thyroid dysfunction (mainly hyperthyroidism) in the control of thrombocytopenia. Although this issue still remains deb...

    In the recently revised guidelines on the management of thyroid dysfunction during pregnancy, treatment with thyroid hormone (LT4) is not recommended in women without thyroid autoimmunity (TAI) and TSH levels in the range 2.5-4.0 mIU/L, and in a recent study in that particular group of pregnant women, more complications were observed when a treatment with LT4 was given. The objective of the study was therefore to investigate whether variation in thyroid function within the normal (non-pregnant) range in women free of thyroid disease was associated with altered pregnancy outcomes? Cross-sectional data analysis of 1321 pregnant women nested within an ongoing prospective collection of pregnant women's data in a single centre in Brussels, Belgium. Thyroid peroxidase antibodies (TPO-abs), thyroid-stimulating hormone (TSH), free T4 (FT4) and ferritin levels were measured and baseline characteristics were recorded. Women taking LT4, with TAI and thyroid function outside the normal non-pregnant range were excluded. Pregnancy outcomes and baseline characteristics were correlated with all TSH and FT4 levels within the normal range and compared between two groups (TSH cut-off 500 mL) was inversely associated with serum FT4 levels (OR: 0.35; CI 95%: 0.13-0.96); P  = 0.040. Also 10% of women free of thyroid disease had serum TSH levels ≥2.5 mIU/L. Variation in thyroid function during the first trimester within the normal (non-pregnant) range in women free of thyroid disease was not associated with altered pregnancy outcomes. These results add evidence to the recommendation against LT4 treatment in pregnant women with high normal TSH levels and without TPO antibodies. © 2018 European Society of Endocrinology.

    Full text: The role for ultrasound (US) in the assessment of nodular thyroid disease has increased in recent years. This expanded role has been highlighted in recent consensus guidelines on the management of nodular thyroid disease. In this review, we address the potential roles for US in assessing thyroid nodules and review these recent guidelines. In particular, we review the evidence that US characteristics of thyroid nodules can predict the risk of malignancy. A predominantly solid nodule, hypoechogenicity, microcalcification, macrocalcification, ill-defined margins, intranodular vascularity, and taller-than-wide shape have all been associated with increased risk of malignancy, but no single US characteristic is sufficiently sensitive or specific to exclude or diagnose malignancy by itself. However, the use of combinations of US characteristics to stratify nodules into high and low risk for malignancy appears a promising strategy. Unselected nodules without any suspicious US features have a low risk of malignancy (<2%), whereas malignancy rates are much higher in nodules with at least two suspicious features. Recent guidelines endorse this approach of using combinations of US features to guide nodule selection for fine needle aspiration.

    This study evaluates F-18-FDG PET of the thyroid in Graves' disease. Methods: Thirty patients were investigated the day before radioiodine therapy, 15 patients 3-10 days after radioiodine therapy. Twenty patients with cancer of the head or neck and normal thyroid function served as controls. Results: F-18-FDG uptake was higher in Graves' disease patients than in controls. Negative correlations of F-18-FDG uptake with half-life of radioiodine and absorbed radiation dose due to radioiodine therapy were found along with a positive correlation to autoantibody levels. Conclusion: Thus F-18-FDG PET is likely to give information on the biological activity of Graves' disease as well as on early radiation effects. (orig.) [de

    2016-01-01

    Differentiated thyroid carcinoma (DTC) comprises over 90% of thyroid tumors and includes papillary and follicular carcinomas. Patients with DTC have an excellent prognosis, with a 10-year survival rate of over 90%. However, the risk of recurrent tumor ranges between 5% and 30% within 10 years of the initial diagnosis. Cervical lymph node disease accounts for the majority of recurrences and in most cases is detected during follow-up by ultrasound or elevated levels of serum thyroglobulin. Recurrent disease is accompanied by increased morbidity. The mainstay of treatment of nodal recurrence is surgical management. We provide an overview of the literature addressing surgical management of recurrent or persistent lymph node disease in patients with DTC. PMID:26886954

    Routinely available radioassay kits have recently enabled the measurement of serum concentrations of thyroxine binding globulin (TBG) and thyroxine (T 4 ), both total (TT 4 ) and free (FT 4 ) in various disease conditions. Serum TBG and T 4 level were measured in variety of non-thyroidal diseases, of which significance was evaluated in comparison with that in thyroidal diseases. Abnormal serum TBG concentrations in various non-thyroidal diseases and pregnancy result in abnormal serum TT 4 levels, which may cause difficulty in differentiation of these conditions from hyper- or hypothyroidal states. Serum FT 4 levels give better indicator than TT 4 , though the difference among RIA kits are considerably large. However, measurement of serum FT 4 levels alone is not sufficient to distinguish non-thyroidal disease from thyroidal diseases with abnormal thyroidal function. The differentiation has to be based on the combination of clinical findings and results of multiple thyroidal function tests

    The purpose of this study was to assess the frequency and sonographic and laboratory characteristics of Graves disease with intrathyroid hypovascularity in Japanese patients and to compare these characteristics in patients with painless thyroiditis. A total of 194 consecutive patients with Graves disease and 21 patients with painless thyroiditis were enrolled. The patients underwent thyroid volume measurement, mean superior thyroid artery peak systolic velocity (PSV) measurement, power Doppler sonography, and proper blood testing to discriminate between Graves disease and painless thyroiditis. Based on the power Doppler sonographic findings, they were divided into 4 groups: from pattern 0 (most hypovascular thyroid) to pattern III (most hypervascular thyroid). Comparisons of multiple thyroid parameters were made among the groups. The prevalence of Graves disease with pattern 0 (n = 27) was 13.9% among the patients with Graves disease. The sonographic and laboratory data for patients with Graves disease and pattern 0 were compared to those of the 21 patients with painless thyroiditis, which typically shows intrathyroid hypovascularity. Free triiodothyronine and thyroxine levels and the superior thyroid artery PSV were significantly lower in patients with Graves disease and pattern 0 than those with patterns I, II, and III (P thyroid volume and thyrotropin receptor antibody level were significantly lower in patients with Graves disease and pattern 0 than those with pattern III. In the comparison between patients with Graves disease and pattern 0 and those with painless thyroiditis and pattern 0, apart from thyrotropin receptor antibody, only the superior thyroid artery PSV was different. Although the clinical features of patients with Graves disease and intrathyroid hypovascularity were similar to those patients with painless thyroiditis, the superior thyroid artery PSV showed a moderate ability to discriminate these patients. © 2014 by the American Institute of

    To investigate the association of systemic lupus erythematosus (SLE) with thyroid diseases in a medical center in central Taiwan. This is a retrospective cohort of 2796 SLE patients in a tertiary referral medical center from 2000 to 2013. We screened SLE by catastrophic illness registration from national insurance bureau; and thyroid diseases by ICD 9 codes, then confirmed by thyroid function test, auto-antibody, medical and/or surgical intervention. We compared the rate of hyperthyroidism, hypothyroidism and autoimmune thyroid disease (AITD) in SLE patients and the 11,184 match controls. We calculated the rate of these thyroid diseases and positive antibodies to thyroglobulin (ATGAb), thyroid peroxidase (TPOAb) in SLE patients grouped by the presence of overlap syndrome and anti-dsDNA antibody. We also compared the association of thyroid diseases to severe SLE conditions, including renal, central nervous system (CNS) involvement, and thrombocytopenia. Compared to the matched controls, the cumulative incidence of thyroid disease, including hyperthyroidism, hypothyroidism and AITD, were all higher in SLE patients (p hyperthyroidism. SLE patients with thyroid diseases also carry higher risk for severe complications such as renal involvement (p = 0.024) central nervous system involvement (p hyperthyroidism, hypothyroidism, and AITD than the matched control. Among lupus patients, the risks of thyroid diseases are even higher in the presence of overlap syndrome. SLE patients with thyroid diseases had higher risk of renal and CNS involvement.

    The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3 rd version. (orig.) [de

    Full Text Available Background. In recent years there has been a tendency of increase in the proportion of nodular goiter and Graves’ disease in thyroid pathology in children, which necessitates a choice of rational tactics for treatment of these diseases. At present there is no optimal method of treatment for thyroid gland pathology, but one of the methods is surgery. Thyroid surgery due to the determination of the indications and choice of the optimal volume of the surgical intervention continues to be under debate as postoperative complications of surgical treatment of thyroid diseases in children are possible.Aim: to study the outcomes of surgical treatment for thyroid pathology in children, depending on the volume of operation.Materials and methods. This article presents the results of a survey of 77 children operated on in the period of 2002–2016 for Graves’ disease, single-node goiter, and multinodular goiter. The examination included the determination of the levels of ionized calcium and TSH, FT4, FT3 in the blood serum, the evaluation of the functional state of the pituitary-thyroid system, thyroid ultrasound examination, and examination by an otolaryngologist.Results. The incidence of adverse outcomes of surgical treatment in children with nodular goiter was 27%. Adverse outcomes were observed equally often after organ-preserving operations and after thyroidectomy, but they were of different structure. The frequency of postoperative complications after thyroidectomy performed on the nodular goiter was 27%. Complications presented as postsurgical hypoparathyroidism and vocal cord paresis. In children with nodular goiter, after thyroidectomy hypoparathyroidism occurred more frequently than paresis of the vocal folds. Symptomatic hypocalcemia was observed more frequently than the asymptomatic variant, and in most cases hypoparathyrodism was transient. Among children with a single-node goiter who underwent organ-preserving surgery on the thyroid gland

    Traditionally, thyroid imaging has been performed primarily using radionuclide scanning. High-resolution computed tomography (CT) was performed in 18 patients to evaluate the CT appearance of various thyroid abnormalities including diffuse toxic goiter, multinodular goiter, Hashimoto thyroiditis, thyroid adenoma, and malignant thyroid tumors. CT images of the thyroid were correlated with radionuclide scanning, surgical findings, and clinical and laboratory results. CT provided a complementary method for evaluation of the thyroid by defining the morphology of the thyroid gland and more precisely defining the anatomic extent of thyroid abnormalities in relation to the normal structures of the neck and mediastinum

    Objective: To study the color doppler image characteristics of thyroid arteries pre- and post-interventional procedure and to assess the clinical efficacy in Gnaves' disease. Methods: 11 from 31 patients diagnosed as Graves' disease undertaken thyroid arteries embolization, were analyzed. Color Doppler sonography was applied to monitor the pre-and post- procedure thyroid size and diameters of thyroid arteries. Power Doppler was used to detect the Vmax, Vmin, RI and blood flow. Results: After thyroid arteries embolization, the size and vascularity of thyroids were reduced. The thyroid arteries showed shrinkage and stoppage blood flow at the embolized site. The changes of RI, blood parameters of Vmax, Vmin and diameters of the thyroid arteries pre- and post-procedure turned out to be statistically significant for clinical restriction. Conclusion: The color Doppler sonography plays an important role for preoperative diagnosis and predicting the prognosis

    AIM: To evaluate the role of thyroid blood flow assessment by color-flow Doppler ultrasonography in the differential diagnosis of thyrotoxicosis and compare it to technetium pertechnetate thyroid scanning. METHODS: Twenty-six patients with thyrotoxicosis were included in the study. Clinical history was taken and physical examination and thyroid function tests were performed for all patients. Thyroid autoantibodies were measured. The thyroid glands of all patients were evaluated by gray scale ultrasonography for size, shape and echotexture. Color-flow Doppler ultrasonography of the thyroid tissue was performed and spectral flow analysis of both inferior thyroid arteries was assessed. Technetium99 pertechnetate scanning of the thyroid gland was done for all patients. According to thyroid scintigraphy, the patients were divided into two groups: 18 cases with Graves’ disease and 8 cases with Hashimoto’s thyroiditis. All patients had suppressed thyrotropin. The diagnosis of Graves’ disease and Hashimoto’s thyroiditis was supported by the clinical picture and follow up of patients. RESULTS: Peak systolic velocities of the inferior thyroid arteries were significantly higher in patients with Graves’ disease than in patients with thyroiditis (P = 0.004 in the right inferior thyroid artery and P = 0.001 in left inferior thyroid artery). Color-flow Doppler ultrasonography parameters demonstrated a sensitivity of 88.9% and a specificity of 87.5% in the differential diagnosis of thyrotoxicosis. CONCLUSION: Color Doppler flow of the inferior thyroid artery can be used in the differential diagnosis of thyrotoxicosis, especially when there is a contraindication of thyroid scintigraphy by radioactive material in some patients.

    Full Text Available Graves′ disease is the most common cause of hyperthyroidism in children. Most children and adolescents are treated with anti-thyroid drugs as the initial modality. Studies have used Methimazole, Carbimazole and Propylthiouracil (PTU either as titration regimes or as block and replacement regimes. The various studies of anti-thyroid drug (ATD treatment of Graves′ disease in pediatric patients differ in terms of the regimes, remission rate, duration of therapy for adequate remission, follow up and adverse effects of ATD. Various studies show that lower thyroid hormone levels, prolonged duration of treatment, lower levels of TSH receptor antibodies, smaller goiter and increased age of child predicted higher chance of remission after ATD. A variable number of patients experience minor and major adverse effects limiting initial and long term treatment with ATD. The adverse effects of various ATD seem to more in children compared to that of adults. In view of liver injury including hepatocellular failure need of liver transplantation associated with PTU, the use has been restricted in children. The rate of persistent remission with ATD following discontinuation is about 30%. Radioactive iodine therapy is gaining more acceptance in older children with Graves′s disease in view of the limitations of ATD. For individual patients, risk-benefit ratio of ATD should be weighed against benefits of radioactive iodine therapy and patient preferences.

    Thyroid disease and hyperparathyroidism are the most common endocrine disorders. The incidence of thyroid disease in patients with hyperparathyroidism ranges in the different series from 17 to 84%, and thyroid cancer occurs with an incidence ranging from 2 to 15%. The aim of our study was to analyze the management of elderly patients with concomitant thyroid and parathyroid disease in order to define the best surgical therapeutic strategy and avoid reoperations associated with a higher risk of complications. All consecutive patients (64 patients, age range 60-75 years), undergoing surgery for hyperparathyroidism, from January 2011 to June 2014, were retrospectively evaluated. Enrolled patients were divided into two study groups of patients affected by hyperparathyroidism with or without a concomitant thyroid disease. Out of 64 patients enrolled in our study (24 men, age range 60-75 years), affected by hyperparathyroidism, 34 had an associated thyroid disease and were treated with total thyroidectomy and parathyroidectomy. The group, who underwent parathyroidectomy associated with thyroidectomy, had no greater complications than the group receiving only parathyroidectomy. Thyroid disease must be excluded in patients affected by hyperparathyroidism. It is difficult to determine whether hyperparathyroidism can be considered a risk factor for thyroid disease, but an accurate preoperative study is essential for a surgery able to treat both thyroid and parathyroid disease. In this way, we avoid the elderly patient, with associated morbidity and increased surgical risk, to undergo a reoperation for thyroid disease, burdened with major complications.

    Toxoplasmosis, one of the most common zoonotic diseases worldwide, can induce various hormonal and behavioural alterations in infected hosts, and its most common form, latent toxoplasmosis, influences the course of pregnancy. Autoimmune thyroid diseases (AITD) belong to the well-defined risk factors for adverse pregnancy outcomes. The aim of this study was to investigate whether there is a link between latent toxoplasmosis and maternal AITD in pregnancy. Cross-sectional study in 1248 consecutive pregnant women in the 9-12th gestational weeks. Serum thyroid-stimulating hormone (TSH), thyroperoxidase antibodies (TPOAb), and free thyroxine (FT4) were assessed by chemiluminescence; the Toxoplasma status was detected by the complement fixation test (CFT) and anti-Toxoplasma IgG enzyme-linked immunosorbent assay (ELISA). Overall, 22.5% of the women were positive for latent toxoplasmosis and 14.7% were screened positive for AITD. Women with latent toxoplasmosis had more often highly elevated TPOAb than the Toxoplasma-negative ones (p = 0.004), and latent toxoplasmosis was associated with decrease in serum TSH levels (p = 0.049). Moreover, we found a positive correlation between FT4 and the index of positivity for anti-Toxoplasma IgG antibodies (p = 0.033), which was even stronger in the TPOAb-positive Toxoplasma-positive women, (p = 0.014), as well as a positive correlation between FT4 and log2 CFT (p = 0.009). Latent toxoplasmosis was associated with a mild increase in thyroid hormone production in pregnancy. The observed Toxoplasma-associated changes in the parameters of AITD are mild and do not seem to be clinically relevant; however, they could provide new clues to the complex pathogenesis of autoimmune thyroid diseases.

    We aimed to identify the best approach to work ability assessment in patients with thyroid disease by evaluating the factor structure, measurement equivalence, known-groups validity, and predictive validity of a broad set of work ability items. Based on the literature and interviews with thyroid patients, 24 work ability items were selected from previous questionnaires, revised, or developed anew. Items were tested among 632 patients with thyroid disease (non-toxic goiter, toxic nodular goiter, Graves' disease (with or without orbitopathy), autoimmune hypothyroidism, and other thyroid diseases), 391 of which had participated in a study 5 years previously. Responses to select items were compared to general population data. We used confirmatory factor analyses for categorical data, logistic regression analyses and tests of differential item function, and head-to-head comparisons of relative validity in distinguishing known groups. Although all work ability items loaded on a common factor, the optimal factor solution included five factors: role physical, role emotional, thyroid-specific limitations, work limitations (without disease attribution), and work performance. The scale on thyroid-specific limitations showed the most power in distinguishing clinical groups and time since diagnosis. A global single item proved useful for comparisons with the general population, and a thyroid-specific item predicted labor market exclusion within the next 5 years (OR 5.0, 95 % CI 2.7-9.1). Items on work limitations with attribution to thyroid disease were most effective in detecting impact on work ability and showed good predictive validity. Generic work ability items remain useful for general population comparisons.

    Thyroid disorders were seen in eight of 25 atomic bomb survivors with Sjoegren's disease -- simple goiter in 2, chronic thyroiditis in 4, and primary hypothyroidism probably arising from chronic thyroiditis in 2. Thyroid disorders associated with Sjoegren's disease seemed to occur frequently in survivors exposed near the explosion. One of the two survivors with primary hypothyroidism had been exposed to atomic bomb 1.7 km from the explosion. As for the other clinical laboratory findings, there was no significant difference between the group with thyroid disorders and the group without them. (Namekawa, K.)

    The postoperative volume of the thyroid glands was measured using computed tomography (CT) in 16 patients with Basedow's disease. In the group which had normal postoperative thyroid function and did not need to receive T 4 , CT showed increase of thyroid volume. In three of the four patients who needed to receive it, CT showed decreased thyroid volume, as compared with that immediately after operation. CT has proved to serve as a tool for measuring postoperative thyroid volume for Basedow's disease in relation to postoperative prognosis. (Namekawa, K.)

    98 patients with Graves' disease have been compared to 95 patients with Hashimoto's thyroiditis and to 97 patients with benign thyroid nodules (control group) in order to evaluate the triggering role of major stressors and pregnancy in the occurrence of autoimmune thyroid diseases. A stress factor has been encountered in 11% cases of Graves' disease and in 6% of Hashimoto's and thyroid nodes (chi 2 test, not different). Graves' disease occurred after a pregnancy in 25% of the women in child bearing age versus 10% of the cases of Hashimoto's (p thyroid nodes. The role of stressors, if any, in triggering Graves' disease seems to be weak and dubious compared to the role of pregnancy and post-partum. It is assumed that the decrease of immunosuppressive hormones occurring after stress or delivery could induce a rebound autoimmune reaction responsible for the thyroid disease. In Hashimoto's thyroiditis, stress and pregnancies do not seem to have any triggering role.

    Graves' disease is a common cause of thyrotoxicosis. Treatment options include anti-thyroid medications or definitive therapy: thyroidectomy or radioactive iodine (I(131) ). Traditionally, I(131) has been the preferred definitive treatment for Graves' disease in New Zealand. Reports of concomitant thyroid cancer occurring in up to 17% of Graves' patients suggest surgery, if performed with low morbidity, may be the preferred option. The aim of this study was to determine the rate of thyroid cancer and surgical outcomes in a New Zealand cohort of patients undergoing thyroidectomy for Graves' disease. This study is a retrospective review of Waikato region patients undergoing thyroid surgery for Graves' disease during the 10-year period prior to 1 December 2011. A total of 833 patients underwent thyroid surgery. Of these, 117 were for Graves' disease. Total thyroidectomy was performed in 82, near-total in 33 and subtotal in 2 patients. Recurrent thyrotoxicosis developed in one subtotal patient requiring I(131) therapy. There were two cases of permanent hypoparathyroidism and one of permanent recurrent laryngeal nerve palsy. Eight patients (6.8%) had thyroid cancer detected, none of whom had overt nodal disease. Five were papillary microcarcinomas (one of which was multifocal), two were papillary carcinomas (11 mm and 15 mm) and one was a minimally invasive follicular carcinoma. Thyroid cancer was identified in approximately 7% of patients undergoing surgery for Graves' disease. A low complication rate (<2%) of permanent hypoparathyroidism and nerve injury (<1%) supports surgery being a safe alternative to I(131) especially for patients with young children, ophthalmopathy or compressive symptoms. © 2012 The Authors.

    In the experiments with the thyroid phantom and first studies of patients with hyperthyroidism it was proved that in combining SPECT imaging technique and high resolution ability of pinhole collimator (commonly used for conventional scintigraphy of the thyroid) it is possible to obtain quantitative information concerning the structure and unhomogenities of the thyroid tissue , not available tom the planar imaging. The following applications of the the method are expected: 1) Estimation of the thyroid dimensions and volume for the accurate dosimetry of the following Iodine-131 - therapy. 2) Determination of the location of the thyroid in the neck , occurrences of the retrotracheal, retrolaryngeal and retrostemal extension of the goiter. 3) Estimation of the structure and unhomogenities of the thyroid gland . 4) Locations and dimensions of cold nodules in the thyroid tissue . Some of these applications are illustrated in our studies of the patients with different thyroid gland diseases (authors).

    Although Sjös syndrome (SS) is the most common disease causing xerostomia, autoimmune thyroid diseases can also affect the salivary glands. The aim of our study was to estimate the prevalence of thyroid diseases (TD) in subjects with symptoms of xerostomia and evaluate the efficacy of salivary gland scintigraphy (SGS) in the detection of TD in patients with SS and without SS. We retrospectively reviewed the SGS findings of 173 subjects (men:women, 29:144) with symptoms of xerostomia. Ejection fractions (EF) in the parotid and submandibular glands were calculated. Thyroid disease was diagnosed on the basis of the results of the visual assessment of tracer uptake in the thyroid gland on SGS images as well as serological thyroid function tests. Based on the American-European Criteria, 94 patients were diagnosed with SS. Hashimoto's thyroiditis was diagnosed in 63 patients, subacute thyroiditis in 23, subclinical hypothyroidism in five, and Graves' disease in one. There were significant differences in the EF values of the parotid and submandibular glands between patients with TD and those with undetermined diagnoses. More than half of patients with xerostomia exhibited TD. Thyroid assessment by SGS is feasible, and SGS appears to be useful for the patients with xerostomia caused by TD. SGS may be the first imaging modality capable of evaluating both salivary gland function and thyroid gland status in patients with xerostomia. This strategy would make the requirement for additional workup for thyroid disease.

    Iodine fortification (IF) may contribute to changes in costs of thyroid disease treatment through changes in disease patterns. From a health economic perspective, assessment of the development in costs of thyroid disease treatment in the population is pertinent. To assess the trends in annual medicine and hospital costs of thyroid disease treatment during 1995-2015 in Denmark, i.e., before and after the introduction of mandatory IF in 2000. Information on treatments for thyroid disease (antithyroid medication, thyroid hormone therapy, thyroid surgery, and radioiodine treatment) was obtained from nationwide registers. Costs were valued at 2015 prices using sales prices for medicines and the Danish Diagnosis-Related Group (DRG) and Danish Ambulatory Grouping System (DAGS) tariffs of surgeries/radioiodine treatments. Results were adjusted for changes in population size and age and sex distribution. The total direct medicine and hospital costs of thyroid disease treatment increased from EUR ∼190,000 per 100,000 persons in 1995 to EUR ∼270,000 per 100,000 persons in 2015. This was mainly due to linearly increased costs of thyroid hormone therapy and increased costs of thyroid surgery since 2008. Costs of antithyroid medication increased slightly and transiently after IF, while costs of radioiodine treatment remained constant. Costs of thyroid hormone therapy and thyroid surgery did not follow the development in the prevalence of hypothyroidism and structural thyroid diseases observed in concurrent studies. The costs of total direct medicine and hospital costs for thyroid disease treatment in Denmark increased from 1995 to 2015. This is possibly due to several factors, e.g., changes in treatment practices, and the direct effect of IF alone remains to be estimated.

    Unilateral Graves' disease is a rare disease variant that can occur in a bilobar thyroid gland. We report the first documented case of unilateral Graves' disease in the left lobe of a bilobar thyroid gland and review the pertinent literature. A 48-year-old man presented in June 2010 with thyrotoxicosis. I-131 radioisotope uptake was elevated at 33.4%, and scintigraphy revealed that uptake of the radioisotope was uniformly increased in the left lobe of the thyroid gland. Ultrasonography of the thyroid gland revealed a non-nodular, enlarged, and heterogeneous left lobe; Doppler investigation of the lobe showed hypervascularity classically seen in Graves' disease. The right lobe of the thyroid, on the other hand, appeared homogeneous and hypovascular on ultrasonography. Thyroid-stimulating immunoglobulin was significantly elevated at 191% (reference range disease was the most likely diagnosis. As has occasionally been described in the literature, unilateral involvement of the thyroid gland is a rare presentation of Graves' disease. Pre-existing functional or structural differences (either congenital or acquired) between the two lobes may contribute to this rare presentation. To our knowledge, this is the first reported case of unilateral Graves' disease presenting in the left lobe of a bilobar thyroid gland. Although the pathophysiology of unilateral Graves's disease has not been clearly elucidated, clinicians should be aware that Graves' disease can present unilaterally in either lobe of the thyroid gland.

However, calculation......, and they may even interact mutually and counteract each other. Numerous studies have evaluated the effect of (131)I therapy, but results have been conflicting due to differences in design, sample size, patient selection, and dose calculation.

    An investigation of the long-term effects of childhood scalp irradiation demonstrated a significantly increased risk of thyroid tumors in the irradiated population. Because of the complexity of thyroid cancer diagnosis, a histopathologic slide review of 59 of the 68 patients (irradiated and nonirradiated) with thyroid disease was undertaken. The review revealed 90% agreement (kappa = +0.85, P less than 0.01) between the original and review diagnosis. Four of 27 cases previously diagnosed as malignant were reclassified as benign, yielding a cancer misdiagnosis rate of 14.8%. All four of the misdiagnosed cancers were of follicular or mixed papillary-follicular type. As a result of the histologic review, the ratio of malignant to benign tumors decreased from 2.55 to 1.75. Since disagreement in diagnosis was similar in the irradiated and nonirradiated groups, the relative risk of radiation-associated neoplasms did not change substantially. The histopathologic review shows that although there were some problems in diagnostic reproducibility, they were not statistically significant and did not alter our previous conclusions regarding radiation exposure. However, a 15% reduction in the number of malignancies might affect epidemiologic studies with an external comparison as well as geographic or temporal comparisons

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48±13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease

    Thyroid storm is a condition in which multiple organ dysfunction results from failure of the compensatory mechanisms of the body owing to excessive thyroid hormone activity induced by some factors in patients with thyrotoxicosis. While diabetic ketoacidosis (DKA) is an important trigger for thyroid storm, simultaneous development of DKA and thyroid storm is rare. A 59-year-old woman with no history of either diabetes mellitus or thyroid disease presented to our hospital because of developing nausea, vomiting and diarrhea for 2 days. Physical examination showed mild disturbance of consciousness, fever, and tachycardia. There were no other signs of thyrotoxicosis. Laboratory studies revealed elevation of random blood glucose and glycosylated hemoglobin, strongly positive of urine acetone, and metabolic acidosis. Since DKA was diagnosed, we initiated the patient on treatment with administration of insulin and adequate fluid replacement. Although the hyperglycemia and acidosis were immediately relieved, the disturbance of consciousness and tachycardia remained persistent. Levels of FT3 and FT4 were extremely high and TSH was below the detectable limit. TRAb was positive. The thyroid storm score of Burch & Wartofsky was 75/140, and the thyroid storm diagnostic criteria of the Japan Thyroid Association were satisfied. Oral administration of thiamazole, potassium iodide and propranolol resulted in immediate relief of the tachycardia. We encountered a case of thyroid storm associated with Graves' disease covered by DKA. Thyroid storm and DKA are both potentially fatal, and the prognosis varies depending on whether or not these conditions are detected and treated sufficiently early. The thyroid storm diagnostic criteria prepared in 2008 by the Japan Thyroid Association are very simple as compared to the Burch & Wartofsky scoring system for thyroid storm. The Japanese criteria may be useful in the diagnosis of this condition since they enable clinicians to identify a broad

    Graves' disease is an autoimmune disease caused by the production of auto-antibodies against the thyroid-stimulating hormone receptor, which stimulates follicular cell production of thyroid hormone. It is the commonest cause of hyperthyroidism and may cause considerable morbidity with increased risk of cardiovascular and respiratory adverse events. Five per cent of people with Graves' disease develop moderate to severe Graves' ophthalmopathy. Thyroid surgery for Graves' disease commonly falls into one of three categories: 1) total thyroidectomy, which aims to achieve complete macroscopic removal of thyroid tissue; 2) bilateral subtotal thyroidectomy, in which bilateral thyroid remnants are left; and 3) unilateral total and contralateral subtotal thyroidectomy, or the Dunhill procedure. Recent American Thyroid Association guidelines on treatment of Graves' hyperthyroidism emphasised the role of surgery as one of the first-line treatments. Total thyroidectomy removes target tissue for the thyroid-stimulating hormone receptor antibody. It controls hyperthyroidism at the cost of lifelong thyroxine replacement. Subtotal thyroidectomy leaves a thyroid remnant and may be less likely to lead to complications, however a higher rate of recurrent hyperthyroidism is expected and revision surgery would be challenging. The choice of the thyroidectomy technique is currently largely a matter of surgeon preference, and a systematic review of the evidence base is required to determine which option offers the best outcomes for patients. To assess the optimal surgical technique for Graves' disease and Graves' ophthalmopathy. We searched the Cochrane Library, MEDLINE and PubMed, EMBASE, ClinicalTrials.gov, and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). The date of the last search was June 2015 for all databases. We did not apply any language restrictions. Only randomised controlled trials (RCTs) involving participants with a diagnosis

    Scintigraphic study with 131 I and 201 TlCl was performed on the differential diagnosis of various kinds of thyroid disease. When thyroid nodules are cold by scintigraphy with 131 I and hot with 201 TlCl, the lesions were proved to be solid tumor, that is, mostly follicular adenoma and carcinoma, and also most probably chronic thyroiditis. Accumulation of 201 TlCl, however, is not observed in cystic lesions, and is very high with high frequency in metastatic lesion of the lymph nodes as well as the thyroid cancer, especially in well differentiated follicular carcinoma. Therefore 201 TlCl was very useful to confirm the metastatic tumors from the thyroid cancer. These features in accumulation of 131 I and 201 TlCl in thyroid disease suggest the imaging technique with 201 TlCl combined with 131 I seem to provide more pathological information on the thyroid and metastatic lesions.

    Subacute thyroiditis is a common inflammatory disorder of the thyroid gland, possibly of viral etiology, that typically presents with neck pain, fever and tenderness on palpation of the thyroid gland. Graves' disease is an autoimmune thyroid disorder caused by stimulation of the thyroid gland by thyrotropin receptor antibodies (TRAb). The development of Graves´ disease and subacute thyroiditis simultaneously is an uncommon condition and only a few cases have been reported. In this article we present a case of a 46-year old woman diagnosed with Graves´ disease who was started on thiamazole and weeks later developed high fever. Several differential diagnoses were considered such as infection, lymphoma and vasculitis due to thiamazole. Finally, the fine needle aspiration of the thyroid gland displayed histopathological features of subacute thyroiditis. Remarkably, our patient did not have neck pain or tenderness on palpation of the thyroid gland and overall the clinical presentation of subacute thyroiditis was atypical. Thus, subacute thyroiditis may be considered as a potential cause of fever of unknown origin.

    Associations between vitiligo and thyroid diseases have been reported repeatedly. We investigated the associations between vitiligo and overt autoimmune thyroid diseases and thyroid cancer using the Korean National Health Insurance claims database. We defined patients with vitiligo as those whose records showed ≥4 physician contacts between 2009 and 2013 in which vitiligo was the principal diagnosis. We also established an age- and sex-matched control group without vitiligo (2 per 1 vitiligo patient). The outcomes of interest were concurrent Graves disease and Hashimoto thyroiditis (the patients were taking relevant thyroid medications) and thyroid cancer. The study enrolled 73,336 vitiligo patients and 146,672 controls. Patients with vitiligo were at increased risks of Graves disease (odds ratio [OR] 2.610 [95% confidence interval {CI} 2.319-02.938]), Hashimoto thyroiditis (OR 1.609 [95% CI 1.437-1.802]), and thyroid cancer (OR 1.127 [95% CI 1.022-1.242]), compared with the controls. The associations were consistently stronger in males and younger patients. Individual clinical information was not available, and the homogeneous population may limit the generalizability of the results. Vitiligo was significantly associated with overt autoimmune thyroid diseases and overt thyroid cancer. Copyright © 2016 American Academy of Dermatology, Inc. Published by Elsevier Inc.

    Full Text Available Abstract Background Thyroid physiology is closely related to oxidative changes. The aim of this controlled study was to evaluate the levels of nutritional anti-oxidants such as vitamin C, zinc (Zn and selenium (Se, and to investigate any association of them with parameters of thyroid function and pathology including benign and malignant thyroid diseases. Methods This controlled evaluation of Se included a total of 1401 subjects (1186 adults and 215 children distributed as follows: control group (n = 687, benign thyroid disease (85 children and 465 adults; malignant thyroid disease (2 children and 79 adults. Clinical evaluation of patients with benign thyroid disease included sonography, scintigraphy, as well as the determination of fT3, fT4, TSH, thyroid antibodies levels, Se, Zn, and vitamin C. Besides the routine oncological parameters (TG, TSH, fT4, ultrasound Se was also determined in the cases of malignant disease. The local control groups for the evaluation of Se levels were taken from a general practice (WOMED as well as from healthy active athletes. Blood samples were collected between 8:00 and 10:30 a.m. All patients lived in Innsbruck. Statistical analysis was done using SPSS 14.0. The Ho stated that there should be no differences in the levels of antioxidants between controls and thyroid disease patients. Results Among the thyroid disease patients neither vitamin C, nor Zn nor Se correlated with any of the following parameters: age, sex, BMI, body weight, thyroid scintigraphy, ultrasound pattern, thyroid function, or thyroid antibodies. The proportion of patients with benign thyroid diseases having analyte concentrations below external reference cut off levels were 8.7% of cases for vitamin C; 7.8% for Zn, and 20.3% for Se. Low Se levels in the control group were found in 12%. Se levels were significantly decreased in cases of sub-acute and silent thyroiditis (66.4 ± 23.1 μg/l and 59.3 ± 20.1 μg/l, respectively as well as in

    The incidence of the autoimmune thyroid disease Hashimoto thyroiditis (HT) has increased in recent years, and increasing evidence supports the contribution of excess iodine intake to thyroid disease. In this study, we examined the status of autophagy and apoptosis in thyroid tissues obtained from patients with HT, and we determined the effects of excessive iodine on the autophagy and apoptosis of thyroid follicular cells (TFCs) in an attempt to elucidate the effects of excess iodine on HT development. Our results showed decreases in the autophagy-related protein LC3B-II, and increases in caspase-3 were observed in thyroid tissues from HT patients. Interestingly, the suppression of autophagy activity in TFCs was induced by excess iodine in vitro, and this process is mediated through transforming growth factor-β1 downregulation and activation of the Akt/mTOR signaling pathway. In addition, excess iodine induced autophagy suppression and enhanced reactive oxygen species (ROS) production and apoptosis of TFCs, which could be rescued by the activation of autophagy. Taken together, our results demonstrated that excess iodine contributed to autophagy suppression and apoptosis of TFCs, which could be important factors predisposing to increased risk of HT development.

    The study, supported by program MZ-17, was carried on 4567 inhabitants of the area of Szczecin (2350 females and 2217 males). The population was chosen randomly, according to a simple drawing scheme. All subjects were clinically examined using standardised questionnaires. In 3468 persons (including 1807 girls and women, 1661 boys and men) apart form clinical examination, the assessment of thyrotropin, thyroxine and triiodothyronine in serum and frequency of anti thyroglobulin antibodies and antithyroid membrane and antithyroid membrane antibodies were evaluated. The data indicate that 94% of children in Szczecin's region received the prophylactic dose of iodine, mostly between the 1st and 5th of May 1986. Only 17% of the adults received iodine. The most common preparation was Lugol solution given in a single dose. Among all persons who received iodine, only in 5% of subjects the side effects were noted (mostly in children), including symptoms of gastrointestinal tract (vomiting, abdomen pain) and occasionally intra thyroid side effects (thyroid pains). In examined population the high frequency of thyroid enlargement, mainly in women (up to 43-44% at the age group 30-50 years) was found. The frequency of thyroid enlargement, mainly in women (up to 43-44% at the age group 30-50 years) was found. The frequency of clinical diagnosis of thyroid disease was higher in woman than in man (most of the diffuse goiter, rarely the nodular goiter). The frequency of thyroid enlargement and clinical diagnosis of thyroid disease was not dependent on prophylactic iodine intake. The iodine prophylaxis did not influence on thyroid hormones and TSH serum levels and in frequency of antithyroid antibodies. (author). 1 ref, 6 tabs

    Thyroglobulin (Tg), a glycoprotein, is the principal iodoprotein of the thyroid gland and is the major component of the thyroid mass. As Tg is specific to thyroid gland and thyroid related-cells, its measurement in the circulation is potentially useful to study the pathogenesis, establish the diagnosis and follow the course of thyroid disorders. Serum Tg is a suitable marker for the differentiated thyroid carcinoma after total thyroid ablation by surgery and /sup 131/I treatment. Radioimmunoassay (RIA) and immunoradiometric (IRMA) methodologies are important to measure hormones for diagnosis of various diseases. In addition to /sup 131/I uptake, /sup 131/I whole body scintigraphy and estimation of T3, T4 and TSH levels, serum Tg levels in euthyroids (n=42), hyper thyroids (n=55) and treated cases (thyroidectomy and /sup 131/I ablation) of carcinoma (CA) thyroid were 9.7 - +9.96, 109.9 - +160.3 and 2.2 - + 4.2 respectively. Serum Tg levels were significantly higher (P < 0.005) in hyper thyroids and significantly lower (P < 0.025) in treated CA thyroids when compared with those of euthyroids. In treated patients (surgery and /sup 131/I ablation) serum Tg assay is an excellent method to assess the treatment and recurrence of disease. (author)

    Hashimoto's thyroiditis (HT) and Graves' disease (GD) are two very common organ-specific autoimmune diseases which are characterized by circulating antibodies and lymphocyte infiltration. Although humoral and cellular mechanisms have been classically considered separately in the pathogenesis of autoimmune thyroid diseases (AITD), recent research suggests a close reciprocal relationship between these two immune pathways. Several B- and T-cell activation pathways through antigen-presenting cells (APCs) and cytokine production lead to specific differentiation of T helper (Th) and T regulatory (Treg) cells. This review will focus on the cellular mechanisms involved in the pathogenesis of AITD. Specifically, it will provide reasons for discarding the traditional simplistic dichotomous view of the T helper type 1 and 2 pathways (Th1/Th2) and will focus on the role of the recently characterized T cells, Treg and Th17 lymphocytes, as well as B lymphocytes and APCs, especially dendritic cells (DCs).

    This article aims to provide baseline data and highlight any major deficiencies in the current level of care provided for adult patients with thyroid eye disease (TED). We undertook a prospective, nonrandomized cross-sectional multicenter observational study. During a 3-month period June-August 2014, consecutive adult patients with TED who presented to nominated specialist eye clinics in the United Kingdom, completed a standardized questionnaire. Main outcome measures were: demographics, time from diagnosis to referral to tertiary centre, time from referral to review in specialist eye clinic, management of thyroid dysfunction, radioiodine and provision of steroid prophylaxis, smoking, and TED classification. 91 patients (mean age 47.88 years) were included. Female-to-male ratio was 6:1. Mean time since first symptoms of TED = 27.92 (73.71) months; from first visit to any doctor with symptoms to diagnosis = 9.37 (26.03) months; from hyperthyroidism diagnosis to euthyroidism 12.45 (16.81) months. First, 13% had received radioiodine. All those with active TED received prophylactic steroids. Seven patients who received radioiodine and did not have TED at the time went on to develop it. Then, 60% patients were current or ex-smokers. 63% current smokers had been offered smoking cessation advice. 65% patients had active TED; 4% had sight-threatening TED. A large proportion of patients (54%) were unaware of their thyroid status. Not enough patients are being provided with smoking cessation advice and information on the impact of smoking on TED and control of thyroid function.

    The functional status of the thyroid gland was evaluated in 63 children with Hodgkin's disease, aged 4-15 years, before, in the course of and 5 years after chemoradiation therapy. Thyroxin (T4), triiodothyronine (T) and thyroid-stimulating hormone (TSH) in the blood were assayed. The disease was shown to disrupt the pituitary-thyroid system leading to hypothyroidism development which progressed as the disease advanced. While chemotherapy brought the balance between the peripheral thyroid hormone levels and TSH back to normal, thyroid function decrease again following radiotherapy of the neck. The most pronounced and persistent failure of the pituitary-thyroid system was registered with the total target dose of 30 Gy and higher. Irradiation in a dose of 20 Gy caused less disruption and the function was spontaneously restored within 12 months after the treatment

    Thyroid scintigraphy is commonly used for evaluation of cats with hyperthyroidism, with the thyroid-to-salivary ratio (T/S) being the most common method to quantify the degree of thyroid activity and disease. Calculation of thyroid-to-background ratios (T/B) or percent thyroidal uptake of (99m) TcO(-) 4 (TcTU) has only been reported in a few studies. The purpose of this prospective, cross-sectional study was to evaluate a number of quantitative scintigraphic indices as diagnostic tests for hyperthyroidism, including the T/S, three different T/B, TcTU, and estimated thyroid volume. Of 524 cats referred to our clinic for evaluation of suspected hyperthyroidism, the diagnosis was confirmed (n = 504) or excluded (n = 20) based on results of a serum thyroid panel consisting of thyroxine (T4 ), triiodothyronine (T3 ), free T4 (fT4 ), and thyroid-stimulating hormone (TSH) concentrations. In the hyperthyroid cats, median values for TcTU, T/S, and three T/B ratios were all significantly higher (P hyperthyroidism, but the T/S ratio had the highest test accuracy. The T/S ratio correlated strongly with the TcTU (r = 0.85). However, the TcTU had a higher and more significant correlation (P metabolic activity of the feline adenomatous thyroid gland. © 2016 American College of Veterinary Radiology.

    Aim—To evaluate the expression of ribosomal cistrons in human thyroid epithelial cells (TECs) of patients with Grave's disease, Hashimoto's thyroiditis and benign and malignant tumours of the thyroid gland. Methods—TEC nucleoli were investigated in fine needle biopsy specimens from 10 controls, 39 patients with Grave's disease, 15 with Hashimoto's thyroiditis, 56 with benign, and 15 with malignant tumours of the thyroid. A one step silver staining method was applied. In most cases serum concentrations of thyroxine and triiodothyronine as well as goitre size were determined. In every case 100 TECs were evaluated for the mean numbers of nucleoli and for the average number of argyrophilic nucleolar organiser regions (AgNORs) per nucleus. Results—NORs were activated in all patients, but not in controls. The numbers of AgNORs in patients with Grave's disease were closely correlated with thyroxine or triiodothyronine, or both, concentrations and with the size of the thyroid. In patients with Hashimoto's thyroiditis about 30% of TECs nucleoli did not contain AgNORs, whereas others were heavily impregnated with silver. Compared with controls and benign tumours, the nucleoli of carcinomatous TECs were larger and irregular in shape. The mean number of AgNORs per nucleus in malignant cells was higher than that in their benign counterparts. Conclusions—The mechanism by which NORs are activated in TECs varies depending on the type of lesion. The higher AgNOR score in TECs from malignant tumours can be used to distinguish them from their benign counterparts. Images PMID:16696083

    Objective: To explore the anatomy and imaging manifestations of thyroid arteries for improving the efficiency and lowering the complication in interventional embolization of Graves' disease. Methods: Thyroid arteries were investigated, including 16 adult cadavers (Cadaver group), 8 non-thyropathic patients (Normal group)and 17 Graves patients (Graves group). The inner diameters of the trunk and supplying branches of thyroid artery, the angles between the origination of branches and the beginning of the trunk, and the angles between the trunk of thyroid artery and carotid or subclavian artery were measured. In addition, data of the three groups were statistically analyzed. Results: Many non-thyroid arterial branches arose from thyroid artery, with no statistical difference in their indexes between Cadaver group and Normal group. The thyroid arteries showed much longer, obviously wider in diameter, and larger angles between the trunk of thyroid artery and carotid artery in Graves group than those of Cadaver group and Normal group; outcoming with significant statistical differences; and furthermore, with increase of interglandular branches and dangerous internal and external anastomoses. Conclusions: The specific thyroid arterial changes of Graves' disease are helpful for the interventional embolization. Non-thyroid branches and dangerous anastomoses should not be embolized as far as possible, for decreasing the complications of the interventional procedure for Graves' disease. (authors)

    2008-01-01

    To study the diagnostic value of Th1/Th2 cell cytokine and thyroid autoantibody in autoimmune thyroid diseases (AITD), 28 patients with Graves' disease (GD), 15 patients with hyperthyroidism and thyroiditis (GDIII), 13 patients with Hashimoto's hyperthyroidism (HTL), 21 patients with Hashimoto's thyroiditis(HT)and 20 healthy subjects were enrolled in this study. The serum concentrations of Th1 cytokine (IFN-γ) and Th2 cytokine (IL-4) were determined by ELISA. The serum levels of thyrotropin receptor antibodies (TRAb), thyroglobulin antibodies (TGAb) and thyroid peroxidase antibodies (TPOAb) were measured by RIA. The relationship between the serum levels of IFN-γ, IL-4 and TRAb, TGAb and TPOAb were analyzed. The results showed that IFN-γ levels from higher to lower in different groups were in the order of HT, HTL, GDIII, GD and the IL-4 were GD, GDIII, HTL, HT, respectively. There was significant difference in the IFN-γ (P<0.05) and IL-4 levels (P<0.01) between GDIII and HTL groups. There was no significant difference in TGAb and TPOAb between GDIII and HTL groups. In HT group, IFN-γ levels was positively correlated with TGAb and TPOAb (r=0.67,0.54,P<0.01). In GD group, IL-4 was positively correlated with TRAb (r =0.71,P<0.01). The imbalance of Th1/Th2 cell cytokine reflects pathologic change and abnormality of immune function in AITD patients. The detection of Th1/Th2 cell cytokine combined with thyroid autoantibody may be regarded as an indicator in the diagnosis of autoimmune thyroid diseases. (authors)

    AIM: To assess the role of thyroid disease as a risk for fractures in Crohn's patients.METHODS: A cross-sectional study was conducted from 1998 to 2000. The study group consisted of 210 patients with Crohn's disease. A group of 206 patients without inflammatory bowel disease served as controls. Primary outcome was thyroid disorder. Secondary outcomes included use of steroids, immunosuppressive medications, surgery and incidence of fracture.RESULTS: The prevalence of hyperthyroidism was similar in both groups. However, the prevalence of hypothyroidism was lower in Crohn's patients (3.8 % vs 8.2 %, P=0.05).Within the Crohn's group, the use of immunosuppressive agents (0 % vs11 %), steroid usage (12.5 % vs37 %), small bowel surgery (12.5 % vs 28 %) and large bowel surgery (12.5 % vs27 %) were lower in the hypothyroid subset as compared to the euthyroid subset. Seven (3.4 %) Crohn'spatients suffered fracture, all of whom were euthyroid.CONCLUSION: Thyroid disorder was not found to be associated with Crohn's disease and was not found to increase the risk for fractures. Therefore, screening for thyroid disease is not a necessary component in the management of Crohn's disease.

    1974-01-01

    The 99m Tc-pertechnetate thyroid uptake rates(20 min) were measured in 24 healthy normal subjects, 140 patients with nontoxic goiter and 98 patients with thyrotoxicosis who were treated at the Thyroid Clinic, Seoul National University Hospital, from August 1972 to August 1973. Diagnostic reliabilities and correlations between 99m TcO 4 -thyroid uptake rate (20 min) and other thyroid function tests were evaluated. The observed results were as follows:1) The 99m TcO 4 - thyroid uptake rates (20 min) in normal subjects, euthyroid group and hyperthyroid group were 4.1±0.9%, 5.2±1.8% and 29.7±10.6%. There was a significant difference between the mean of the euthyroid group and the mean of the hyperthyroid group and so differentiation between them can be easy. 2) In the diagnosis of hyperthyroidism, the reliabilities of 99m TcO 4 - thyroid uptake rate(20 min), 131 I thyroid uptake rate (24 hrs), serum T 3 resin uptake rate, serum T 4 and T 7 were 87.9-97.9%, 81.2-94.4%, 87.9-97.9%, 90.5-99.3% and 93.7-100%. 99m TcO 4 -thyroid uptake rate (20 min) is more accurate than 131 I thyroid uptake rate (24 hrs) in the diagnosis of hyperthyroidism. 3) 99m TcO 4 -thyroid uptake rate (20 min) was well correlated with 131 I thyroid uptake rate (24 hrs), serum T 3 resin uptake rate, serum T 4 and T 7 . Points in favor of 99m Tc are that it gives a small radiation dose to the thyroid, that tests can be repeated at the short interval, the study can be completed at a single patient visit and it is particularly well suited for the assessment of thyroid function in patients being treated with an antithyroid drug.

    IgG4-related disease is a newly identified syndrome characterized by high serum IgG4 levels and increased IgG4-positive plasma cells in involved organs. The incidence of IgG4-related thyroiditis in the Caucasian population of Europe is unknown. We investigated formalin-fixed thyroid gland samples of 216 patients (191 Hashimoto's thyroiditis, 5 Riedel's thyroiditis, and 20 goiters, as controls), morphologically, and immunohistochemically. Cases were divided into two groups: IgG4-related Hashimoto's thyroiditis (24 cases) together with Riedel thyroiditis (1 case) and 171 non-IgG4-related thyroiditis. Compared to the non-IgG4-related cases, IgG4-related thyroiditis showed a higher IgG4/IgG ratio (0.6 vs. 0.1, p thyroiditis was diagnosed in 23 of the 24 IgG4-related cases (96 %) and in 13 of 167 (18 %, p > 0.001) non-IgG4-related cases. The single case of IgG4-related Riedel's thyroiditis also showed a higher median IgG4 plasma cell count (56.3 vs. 14.3) and a higher IgG4/IgG ratio (0.5 vs. 0.2) than the four cases of non-IgG4-related Riedel's thyroiditis. Our data suggests the incidence of IgG4-related disease (IgG4-RD) of the thyroid gland in Europe is considerably lower than that observed in other studies. A significant elevation of IgG4-positive plasma cells was only found in a small group of Hashimoto's thyroiditis and then accompanied by intense fibrosis, indicating an association with IgG4-RD. Morphologically, IgG4-RD of the thyroid gland differs from that in other organ systems, exhibiting a dense fibrosis without intense eosinophilia or obliterative phlebitis.

    To evaluate and compare the values of the elasticity index as measured by shear wave elastography in healthy subjects and in patients with autoimmune thyroid disease, in order to establish if this investigation can predict the occurrence of autoimmune thyroid disease. A total of 104 cases were included in the study group: 91 women (87.5%), out of which 52 (50%) with autoimmune thyroid disease diagnosed by specific tests and 52 (50%) healthy volunteers, matched for age and gender. For all the subjects, three measurements were performed on each thyroid lobe and a mean value was calculated. The data were expressed in kPa. The investigation was performed with an Aixplorer system (SuperSonic Imagine, France), using a linear high-resolution 15-4 MHz transducer. The mean value for the elasticity index was similar in the right and the left thyroid lobes, both in normal subjects and in patients with autoimmune thyroid disease: 19.6 ± 6.6 vs. 19.5 ± 6.8 kPa, p = 0.92, and 26.6 ± 10.0 vs. 25.8 ± 11.7 kPa, p = 0.71, respectively. This parameter was significantly higher in patients with autoimmune thyroid disease than in controls (p < 0.001). For a cut-off value of 22.3 kPa, which resulted in the highest sum of sensitivity and specificity, the elasticity index assessed by shear wave elastography had a sensitivity of 59.6% and a specificity of 76.9% (AUROC = 0.71; p < 0.001) for predicting the presence of autoimmune thyroid disease. Quantitative elasticity index measured by shear wave elastography was significantly higher in autoimmune thyroid disease than in normal thyroid parenchyma and may predict the presence of autoimmune thyroid disease.

    Full Text Available Thyroid storm is the life-threatening end-organ manifestation of severe thyrotoxicosis. If left untreated, thyroid storm may cause acute heart failure, multiorgan dysfunction, and death. A high degree of suspicion is necessary to make the diagnosis and start antithyroid medications to decrease mortality. Thyroid storm is generally seen in patients with Graves’ disease but should also be suspected in patients with fever, tachycardia, altered mental status, and risk factors including local trauma to the neck, such as strangulation. Based on our review, we report the first case of thyroid storm after strangulation as the presentation of previously undiagnosed Graves’ disease.

    Full Text Available In celiac disease (CD, for its multifactorial nature, the target organs are not limited to the gut, but include thyroid, liver, skin and reproductive and nervous systems. Between the extraintestinal symptoms associated with CD, autoimmune thyroid diseases (AITDs are more evident, underlining as CD-related autoimmune alterations can be modulated not only by gluten but also by various concurrent endogenous (genetic affinity, over-expression of cytokines and exogenous (environment, nutritional deficiency factors. In their pathogenesis a central role for over-expression of interleukin-15 (IL-15 is shown, by inhibiting apoptosis, leading to the perpetuation of inflammation and tissue destruction. Thyroid is particularly sensitive to selenium deficiency because selenoproteins are significant in biosynthesis and activity of thyroid hormones; besides, some selenoproteins as glutathione peroxidase are involved in inhibiting apoptosis. Thus, selenium malabsorption in CD can be thought as a key factor directly leading to thyroid and intestinal damage. Considering the complexity of this interaction and on the basis of available evidence, the aim of this review is to assess as preventive and therapeutic target the role of IL-15 and selenium in the pathogeneses of both CD and AITD.

    The purpose of the present study was to investigate CT Hounsfield unit (H.U.) of the thyroid in hyperthyroid and euthyroid Graves' disease and destructive thyrotoxicosis. The mean thyroid CT number in 95 controls was 122±18 H.U.(±SD) and did not change significatly with advancing age. The mean thyroid CT number (±SD) of 85±22 H.U. in 60 patients with hyperthyroid Graves' disease was significantly lower than either in normal controls or 116±22 H.U. in 11 patients with euthyroid Graves' disease. Comparison of thyroid hormones and TSH receptor Ab values of untreated patients with a normal and an abnormally low thyroid CT number showed that serum total and free T 3 were significantly higher in the latter group than the former group. With respect to the effect of methimazol (MMI) on the thyroid CT number, in the untreated 10 patients with a low thyroid CT number, the initial mean CT number was 65±11 H.U. and increased significantly to 76±14 H.U. after treatment with MMI. In contrast, in 6 patients with a normal thyroid CT number prior to therapy, the initial mean thyroid CT number was 102±11 H.U. and fell significantly to 84±16 H.U. after treatment with MMI. The thyroid CT number in destructive thyrotoxicosis is markedly decreased to less than 70 H.U. and the mean values of 57±7 H.U. in 6 patients with silent thyroiditis and of 61±5 H.U. in 7 with subacute thyroiditis differ significantly from Graves' disease. In conclusion, the thyroid CT number is significantly reduced in hyperthyroid Graves' disease, normal in euthyroid Graves' disease and markedly decreased in destructive thyrotoxicosis. The high T-3 value seemed to play an important role in the pathogenesis of a decline in the thyroid CT number in Graves' disease. An antithyroid drug therapy caused two different changes in the thyroid CT number, depending on whether the thyroid CT number prior to therapy was normal or low. (author)

    The purpose of the present study was to investigate CT Hounsfield unit (H.U.) of the thyroid in hyperthyroid and euthyroid Graves' disease and destructive thyrotoxicosis. The mean thyroid CT number in 95 controls was 122[+-]18 H.U.([+-]SD) and did not change significatly with advancing age. The mean thyroid CT number ([+-]SD) of 85[+-]22 H.U. in 60 patients with hyperthyroid Graves' disease was significantly lower than either in normal controls or 116[+-]22 H.U. in 11 patients with euthyroid Graves' disease. Comparison of thyroid hormones and TSH receptor Ab values of untreated patients with a normal and an abnormally low thyroid CT number showed that serum total and free T[sub 3] were significantly higher in the latter group than the former group. With respect to the effect of methimazol (MMI) on the thyroid CT number, in the untreated 10 patients with a low thyroid CT number, the initial mean CT number was 65[+-]11 H.U. and increased significantly to 76[+-]14 H.U. after treatment with MMI. In contrast, in 6 patients with a normal thyroid CT number prior to therapy, the initial mean thyroid CT number was 102[+-]11 H.U. and fell significantly to 84[+-]16 H.U. after treatment with MMI.

    Hashimoto's thyroiditis (HT) and Graves' disease (GD) are two opposite poles in the spectrum of autoimmune thyroid disease. On one extreme, HT or Chronic Lymphocytic thyroiditis (CLT) courses, as its name implies, with lymphocytic infiltrates replacing thyroid follicles, resulting in a loss of hormone-producing cells and, thus, primary hypothyroidism. On the other extreme, GD is characterized by primary hyperthyroidism due to stimulating autoantibodies against thyroid-stimulating hormone receptors (TSHRs) localized on thyrocytes' membranes of intact thyroid follicles. The presence of HT after GD or the concomitant combination of these two autoimmune entities ending in HT-depending hypothyroid state is well known. However, occurrence of GD after primary hypothyroidism due to CLT is very rare since thyrocytes with their TSHRs are promptly lost. We report a case in which hyperthyroidism occurred seven months after presentation of primary hypothyroidism and discuss potential mechanisms involved.

    In the matched sample for the Adult Health Study 5553 participants were examined in the ABCC clinic in Hiroshima, Japan during the sixteen month period from July 1958 through October 1959. Thyroid disease was diagnosed for 169 subjects, 152 of whom were female. Simple nontoxic goiter was the most frequently seen thyroid disorder comprising 47 percent of the total, with a sex ratio of 8 to 1 in favor of females. Hiroshima is a coastal city where iodine deficiencies seem unlikely and the various etiological possibilities responsible for nontoxic goiter were reviewed and discussed. Hyperthyroidism was observed in 16 patients of whom 13 were females. One patient with hypothyroidism and 5 with chronic thyroiditis diagnosed by biopsy were seen in the study. Single thyroid nodules were found in 39 patients; the biopsy diagnoses of 19 were listed, 8 of whom were shown to have thyroid carcinoma. Carcinoma of the thyroid was diagnosed microscopically in 12 patients, constituting 7 percent of the total number with thyroid disorders. It was concluded that thyroid disease in Hiroshima warrants further study and it will be of particular interest to carefully observe the Adult Health Study group for the incidence of thyroid nodules and thyroid carcinoma.

    A deep understanding of thyroid pathophysiology is the basis for diagnosing and treating benign thyroid diseases with radioactive materials, known as radiopharmaceuticals, which are introduced into the body by injection or orally. After the radiotracer administration, the patient becomes the emitting source, and several devices have been studied to detect and capture these emissions (gamma or beta-negative) and transform them into photons, parametric images, numbers and molecular information. Thyroid scintigraphy is the only technique that allows the assessment of thyroid regional function and, therefore, the detection of areas of autonomously functioning thyroid nodules. Scintigraphy visualizes the distribution of active thyroid tissue and displays the differential accumulation of radionuclides in the investigated cells, thus providing a functional map. Moreover, this technique is a fundamental tool in the clinical and surgical management of thyroid diseases, including: single thyroid nodules with a suppressed thyroid-stimulating hormone level, for which fine-needle aspiration biopsy (FNAB) is used to identify hot nodules; multinodular goiters, especially larger ones, to identify cold or indeterminate areas requiring FNAB and hot areas that do not need cytologic evaluation, and to evaluate mediastinal extension; the diagnosis of ectopic thyroid tissue; subclinical hyperthyroidism to identify occult hyperfunctioning tissue; follicular lesions to identify a functioning cellular adenoma that could be benign, although such nodules are mostly cold on scintigraphy; to distinguish low-uptake from high-uptake thyrotoxicosis, and to determine eligibility for radioiodine therapy. © 2016 S.

    Version 4 of the guideline for radioiodine therapy for benign thyroid diseases includes an interdisciplinary consensus ondecision making for antithyroid drugs, surgical treatment and radioiodine therapy. The quantitative description of a specific goiter volume for radioiodine therapy or operation was cancelled. For patients with nodular goiter with or without autonomy, manifold circumstances are in favor of surgery (suspicion on malignancy, large cystic nodules, mediastinal goiter, severe compression of the trachea) or in favor of radioiodine therapy (treatment of autonomy, age of patient, co-morbidity, history of prior subtotal thyroidectomy, profession like teacher, speaker or singer). For patients with Graves' disease, radioiodine therapy or surgery are recommended in the constellation of high risk of relapse (first-line therapy), persistence of hyperthyroidism or relapse of hyperthyroidism. After counseling, the patient gives informed consent to the preferred therapy. The period after radioiodine therapy of benign disorders until conception of at least four months was adapted to the European recommendation. (orig.)

    Purpose: The aim of the study is to find out whether the measurement of peak systolic velocity in the inferior thyroid artery (ITA) is a valuable parameter to differentiate autoimmune thyroid diseases (hyper-, normo- or hypofunctional) and to evaluate the efficacy of medical treatment. Material and methods: The ITA of 31 patients (eight with Graves' disease, 23 with subclinical hypothyroidism) was examined with color Doppler and pulsed Doppler. The final diagnosis was obtained by citology and by hormonal and antibodies assays. The patients were monitorized by ultrasound for a period of 8 months. Results: In all the patients with Graves' disease the peak systolic velocity was always over 150 cm/s, while in other autoimmune thyroiditis the peak systolic velocity was within the normal range, and never exceeding 65 cm/s. In the first group, the measurement taken in the ITA showed also the efficacy of the pharmacological treatment earlier and more reliably than the color Doppler pattern obtained in the parenchyma. Conclusions: The color Doppler measurement of the ITA seems to be a promising technique with low-cost and easy approach. In our experience, the color Doppler of the ITA could have a clinical role in the differential diagnosis of diffuse thyroid diseases and in the follow-up of the Graves' disease during medical treatment

    The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3{sup rd} version. (orig.)

    Here we present the case of a 14-yr-old girl who developed thyroid follicular carcinoma accompanied by Graves' disease. She was diagnosed with Graves' disease at 10 yr of age and soon achieved a euthyroid state after starting treatment. When she was 13 yr of age, her hyperthyroidism and goiter worsened despite medical therapy. Multiple nodules were found in her enlarged thyroid gland by ultrasonography. Her serum Tg level seemed within the normal range. She underwent near-total thyroidectomy for control of thyroid function. Histopathological study demonstrated that multiple oxyphilic follicular neoplasms were surrounded by the thyroid tissue compatible with Graves' disease. Capsular invasion was identified in one of the nodules, and thus the histological diagnosis was minimally invasive follicular carcinoma. She did not have signs suggesting metastasis, and has had no relapse for 18 mo after the operation. Although some previous studies showed a high prevalence of thyroid cancer with an aggressive nature in adult patients with Graves' disease, few reports about thyroid cancer accompanied by Graves' disease are available in children. The present case, however, suggests that careful investigation is needed when we detect thyroid nodules or progressive thyroid enlargement, especially in children with Graves' disease.

    The aim of this study was to evaluate the usefulness of diffusion-weighted magnetic resonance imaging (DWMRI) for differentation between Graves' disease and Hashimoto's thyroiditis. Fifty patients (27 Graves diseases and 23 Hashimoto thyroiditis) and twenty healthy volunteers were examined using T1, T2 and DWMRI. The patients were diagnosed on the basis of physical findings and the results of thyroid function tests and serological tests. Circular ROIs were positioned on the bilateral thyroid lobes and isthmus. All measurements were repeated three different b values including 100, 600 and 1000 s/mm2 in all cases. ADC (Apparent diffusion coefficient) maps were calculated automatically with the MR system. Mean ADC values were 2.93 × 10-3, 1.97 × 10-3 and 1.62 × 10-3 mm2/s in the healthy volunteers; 3.47 × 10-3, 2.25 × 10-3 and 1.64 × 10-3 mm2/s in Graves' disease; 2.53 × 10-3, 1.76 × 10-3, 1.28 × 10-3 mm2/s in Hashimoto thyroiditis for b100, b600 and b1000, respectively. The ADC values of the Graves diseases were higher than healty volunteers and Hashimoto thyroiditis. ADC values were statistically significant for differentation between Hashimoto thyroiditis and Graves' disease all b values (p Hashimoto thyroiditis and Graves' disease.

    Female, 11 FINAL DIAGNOSIS: Thyroid storm Symptoms: Diarrhea • tachycardia • tachypnea • tremor • wheezing - Clinical Procedure: - Specialty: - Rare disease. A growing number of pediatric endocrinologists treat Graves disease with radioactive iodine (RAI) therapy due to the typically definitive nature of I-131 therapy. Given the published benefits and perceived low risks of RAI when compared to surgery or long-term anti-thyroid medication, the trend towards therapy with RAI is likely to continue. Nevertheless, RAI is not without significant risk. An 11-year-old girl with newly diagnosed Graves disease received RAI for definitive treatment of her hyperthyroidism. Within 24 hours of receiving I-131, she developed increasing sleepiness and eventually became unresponsive. Upon arrival at the emergency department she had a tonic-clonic seizure and was diagnosed with thyroid storm. Despite best efforts to manage her hyperthyroidism, she suffered a stroke of the left cerebral hemisphere that left her with persistent neurological deficits. Although thyroid storm after thyroid ablation is rare, the significant morbidity and potential mortality of pediatric thyroid storm warrant further studies to determine if children with markedly elevated thyroid hormone concentrations at diagnosis should receive prolonged pretreatment with anti-thyroid drugs. While such an approach may reduce the efficacy of I-131 ablation, it can also reduce and hopefully eliminate the risk of post-ablative thyroid storm.

    2012-01-01

    Purpose of Review Thyroid eye disease (TED) is a poorly understood autoimmune manifestation most commonly associated with Graves’ disease. Current nonspecific treatment paradigms offer symptomatic improvement but fail to target the underlying pathogenic mechanisms and thus, do not significantly alter the long-term disease outcome. The purpose of this review is to provide an update of the current understanding of the immunopathogenesis of TED and explore these implications for targeted immunotherapy. Recent Findings Orbital fibroblasts are integral to the pathogenesis of TED and may modulate immune responses by production of cytokines and hyaluronan in response to activation of shared autoantigens including thyrotropin receptor (TSHR) and insulin-like growth factor-1 receptor (IGF-R1). Fibrocytes share many of these phenotypic and functional features, suggesting a link between systemic and site-specific disease. Use of targeted immunotherapies in TED is limited, though data from the use Rituximab (RTX), a B cell depleting agent, are encouraging. Sustained clinical response has been seen with RTX in several reports, despite return of peripheral B cell levels to pretreatment levels. Additionally, this response appears to be independent to cytokine and antibody production, suggesting possible modulation of antigen presentation as a mechanism of its effect. Summary Progressive advances in the understanding of the immunopathogenesis of TED continue to spur clinical trials utilizing targeted immune therapies. Continued understanding of the molecular mechanisms of disease will expand potential treatments for TED patients and obviate the need for reconstructive surgical therapies. PMID:21730841

    Objective: To investigate the clinical Significance of determination of serum thyroid stimulating hormone receptor antibody (TRAb) levels in patients with thyroid diseases, especially in patients with Graves' disease. Methods: Serum TRAb levels were determined with radio-receptor assay (RRA) in 302 patients with various thyroid diseases and 52 controls. Results: In patients with Graves' disease before treatment (n=62) the positive rate of TRAb was 86.3%. In patients with Graves' diseases improved after treatment (n=60), the positive rate was 74.5%; in those clinically cured (n=68) the positive rate was 32.1%. In 58 patients with Graves' disease who relapsed after apparently cure, the positive rate of TRAb rose to 90.3 %. However, there were no positive TRAb cases in 23 patients with simple goiter and 31 patients with benign thyroid adenomas. Also, there were no positive TRAb cases in the controls. Conclusion: TRAb levels correspond well with the severity of Graves' disease. (authors)

  19. Celiac-Associated Autoimmune Thyroid Disease: A Study of 16 Patients with Overt Hypothyroidism

    1995-01-01

    Full Text Available Previous reports have suggested that autoimmune thyroid disorders (including Hashimoto’s or lymphocytic thyroiditis may occur in patients with celiac disease. In this study, the prevalence of thyroid disease was explored in a series of 96 consecutive patients seen with biopsy-defined adult celiac disease (average age 47.3 years. Sixteen celiac patients (average age 58.1 years were detected with hypothyroidism, including four treated with radio-iodine ablation or thyroidectomy for Grave’s disease. In addition to celiac disease, almost half had dermatitis herpetiformis, a small intestinal neoplasm (particularly lymphoma or both. Diagnosis of thyroid disease preceded diagnosis of celiac disease in 13 patients or was made concurrently in two patients. In only one patient was thyroid disease detected after celiac disease was diagnosed. This indicates that thyroid diseases occur more commonly in celiac disease than is currently appreciated, possibly due to shared embryological origins or common immunopathological features, and may be the presenting clinical manifestation in adults especially if there is coexistent dermatitis herpetiformis. Careful monitoring of this subgroup may be warranted because of the frequency of neoplastic intestinal diseases, particularly lymphoma.

    Improved survival resulting from advances in therapy in patients with Hodgkin's disease is associated with long-term morbidity, including the potential for the development of a second solid malignancy. We report a 44-year-old man with an unusually aggressive course of thyroid carcinoma 15 years after treatment for Hodgkin's disease. In a review of the English-language literature, we found 21 cases of thyroid cancer following radiotherapy for Hodgkin's disease, with latency periods ranging from 6 to 48 years. The development of secondary thyroid cancer after high-dose neck irradiation may be related to hypothyroidism, itself a complication of radiotherapy. Thyroid function should be measured at least once a year in all patients given neck irradiation, with initiation of thyroid hormone replacement if there is evidence of sustained hypothyroidism

    IgG4-positive (+) plasma cells have been reported in both Riedel's thyroiditis (RT) and Hashimoto's thyroiditis (HT). These cells are the hallmark of IgG4-related disease (IgG4-RD). We sought to determine whether RT is part of IgG4-RD spectrum. This was a case-control study performed at a tertiary medical centre. We included RT cases from the period 1958 to 2008 that had sufficient paraffin-embedded tissue for IgG4 immunostaining. Controls were patients with HT, age and gender matched, with similar pathology criteria. The main outcome measures were the intensity of the IgG4 staining and the clinical and histological correlates with IgG4-RD. Six pairs of RT and HT were analysed. The mean age was 44·7 years. In both groups, 5/6 cases had positive IgG4 staining. The mean number of IgG4 + cells/ HPF, normalized to the degree of inflammation, was 3·2 ± 3·0 SD (RT) vs 0·9 ± 0·7 (HT), P = 0·15, for fibrotic areas and 2·1 ± 2·3 SD vs 1·0 ± 0·8 (P = 0·39) for areas with lymphoid aggregates. We found the number of IgG4 +  cells in RT to be inversely correlated with the duration of disease (P = 0·046). Three RT cases had associated comorbidities from the IgG4-RD spectrum while none of the HT cases had such conditions. Riedel's thyroiditis is a component of IgG4-RD with the density of the IgG4 +  lymphocytic infiltrate being time dependent. In this small study, we did not identify differences in IgG4 infiltration between RT and HT, minimizing the utility of this marker in RT diagnosis. © 2016 John Wiley & Sons Ltd.

    Ectopic thyroid tissue an uncommon condition results from abnormal migration of the primitive thyroid bud. This may be the only functional thyroid. Ectopic thyroid tissue may sometimes coexist with the eutopic thyroid gland. Hyperthyroidism in association with ectopic thyroid tissue is very uncommon. We report a rare case of simultaneous involvement of ectopic and eutopic thyroid tissue in a married women of 35 years who was referred to our department for a technetium 99m thyroid scan. Coexisting ectopic and eutopic thyroid tissue due to identical histology may have similar response to various stimulatory and inhibitory factors like hormones and immunoglobulin's. Iodine-131 is an easy to administer and effective treatment for patients with simultaneous Graves’ disease in the ectopic and eutopic thyroid tissues

    1986-01-01

    The regulatory mechanism of the pituitary-thyroid axis in normal subjects and patients with Graves' disease was investigated using a highly sensitive TSH assay based on the immunoradiometric assay. All of the normal subjects had detectable TSH values within the range 0.35 to 6.0 μU/ml. No negative correlations between TSH and free thyroid hormones existed in normal subjects. Patients with thyroid carcinoma who seemed to have normal pituitary-thyroid function showed a rapid increase of TSH after total thyroidectomy. On the other hand, while untreated patients with Graves' disease all had undetectable TSH values, these patients took 1 to 3.5 months longer to normalize their TSH values than to normalize free thyroid hormones on antithyroid drug therapy. During the recovery phase by the treatment with decrease of antithyroid drug or supplement of T 4 from iatrogenic hypothyroid state after treatment for Graves' disease and thyroid carcinoma, normalization of TSH levels was delayed than that of free thyroid hormones. Patients with Graves' disease in remission showed an extremely positive correlation between basal and peak TSH levels in TRH test, and a negative correlation between basal TSH and FT 4 . In conclusion, an individual patient may have a different set point concerning the regulatory mechanism of the pituitary-thyroid axis, and the persistence of the hyperthyroid state would seem to have caused some reversible dysfunction of the pituitary gland.

    Full Text Available Aspects of autoimmune thyroid disease updated in this review include: immunoglobulin G4 (IgG4-related thyroid disease (Riedel's thyroiditis, fibrosing variant of Hashimoto's thyroiditis, IgG4-related Hashimoto's thyroiditis, and Graves' disease with elevated IgG4 levels; recent epidemiological studies from China and Denmark indicating that excess iodine increases the incidence of Hashimoto's thyroiditis and hypothyroidism; immunomodulatory agents (ipilimumab, pembrolizumab, nivolumab activate immune response by inhibiting T-cell surface receptors which down-regulate immune response, i.e., cytotoxic T-lymphocyte antigen 4 and programmed cell death protein 1 pathways; alemtuzumab is a humanised monoclonal antibody to CD52 which causes immune depletion and thyroid autoimmune disease especially Graves' hyperthyroidism; small molecule ligand (SML agonists which activate receptors, SML neutral antagonists, which inhibit receptor activation by agonists, and SML inverse agonists which inhibit receptor activation by agonists and inhibit constitutive agonist independent signaling have been identified. SML antagonism of thyroid-stimulating hormone-receptor stimulatory antibody could treat Graves' hyperthyroidism and Graves' ophthalmopathy; and thyroxine treatment of subclinical hypothyroidism can produce iatrogenic subclinical hyperthyroidism with the risk of atrial fibrillation and osteoporosis. The increased risk of harm from subclinical hyperthyroidism may be stronger than the potential benefit from treatment of subclinical hypothyroidism.

    Full Text Available Patients with Turner’s syndrome (TS are at an increased risk of developing autoimmune thyroid disease (ATD. The aim of this study was to determine the frequency of anti-thyroid peroxidase (anti-Tpo antibodies and ATD in children and adolescent girls with TS. It also assessed the influence of karyotype on the development of thyroid disease. Sixty eight patients with TS were compared with 68 age matched healthy unrelated girls in this study. They were screened for anti-Tpo antibodies, free T4 and TSH levels. Sign and symptoms of hypothyroidism and hyperthyroidism and the presence of goiter were also investigated. Anti-Tpo antibodies were found in 18 (26.4% TS patients and 1 (1.4% patient in the control group (P < 0.001, evenly distributed between the karyotypes 45X, 46X, isoXq and mosaicism. Out of 68 TS patients, 8 (11.7% had visible goiter. Subclinical hypothyroidism and hypothyroidism both occurred in 2 patients (5.9%. These patients were characterized by higher levels of anti-Tpo antibodies. Visible goiter was found in 3 (4.4% subjects of the control group, but all of them were euthyroid. We found that younger patients were more likely to be anti-Tpo negative (P < 0.001. Our data demonstrated a high frequency of ATD in a representative sample of Iranian girls with TS which is in accordance with previous observations. Regular follow up assessment of thyroid autoantibodies and thyroid function in patients with TS is recommended for timely diagnosis of thyroid dysfunction and treatment.

    Postpartum depression(PPD) of women with depression increased frequency of thyroid disease, and so the correlations for depression and thyroid disease has been the subject of discussed whether. The purpose of this study was to predict the prevalence of PPD and the correlation between PPD and thyroid disease through ultrasonography. January 2010 to November 2011, Obstetrics and Gynecology in M-clinical center admitted 230 patients within 1 year postpartum were enrolled. EPDS by PPD scale depression screening and general characteristics of subjects were investigated and thyroid was examined that ultrasonography and thyroid blood tests. A total of 230 patients non PPD group were 53.0% and PPD group were 47.0%. In ultrasonography, among 27 patients who changed in size of thyroid, non PPD group were 14.8% and PPD group were 85.2%. Among 124 patients who thyroid nodules were presence, non PPD were 35.8% and PPD group were 64.2%. In ultrasonography, PPD group were higher incidence than non PPD group were changes in size of thyroid and the presence of nodules. There was significant difference between the changed in size of thyroid and thyroid nodules were presence the two group. Definitive histopathological diagnosis was benign in 33 patients (non PPD group were 45.5%, PPD group were 54.5%), malignancy in 5 patients (only PPD group were 100%), thyroiditis in 3 patients (non PPD group were 33.3%, PPD group were 66.7%). The results of thyroid blood tests, abnormal TSH level were 7 patients (non PPD group were 28.6%, PPD group were 71.4%) and abnormal Free T4 level were 9 patients (non PPD group were 44.4%, PPD group were 55.6%). There was no significant difference between the abnormal TSH level and Free T4 level of the two group. 5 patients were diagnosed as thyroid dysfunction. Of these, 2 patients were subclinical hyperthyroidism in non PPD group, 2 patients were subclinical hyperthyroidism and 1 patient was subclinical hyperthyroidism in PPD group. This study was

    Most publications to date compare outcomes after post-surgical thyroid remnant ablation stimulated by recombinant human thyrotropin (rhTSH) versus thyroid hormone withholding/withdrawal (THW) in low-recurrence risk differentiated thyroid carcinoma (DTC) patients. We sought to perform this comparison in high-risk patients. We retrospectively analyzed ~9-year single-center experience in 70 consecutive adults with initial UICC (Union for International Cancer Control) stage III/IV, M0 DTC undergoing rhTSH-aided (N.=54) or THW-aided (N.=16) high-activity ablation. Endpoints included ablation success and DTC outcome. Assessed ≥1 year post-ablation, ablation success comprised a) no visible scintigraphic thyroid bed uptake or pathological extra-thyroidal uptake; b) undetectable stimulated serum thyroglobulin (Tg) without interfering autoantibodies; c) both criteria. DTC outcome, determined at the latest visit, comprised either 1) "no evidence of disease" (NED): undetectable Tg, negative Tg autoantibodies, negative most recent whole-body scan, no suspicious findings clinically, on neck ultrasonography, or on other imaging; 2) persistent disease: failure to attain NED; or 3) recurrence: loss of NED. After the first ablative activity, ablation success by scintigraphic plus biochemical criteria was 64.8% in rhTSH patients, 56.3% in THW patients (P=NS). After 3.5-year versus 6.2-year median follow-up (P<0.05), DTC outcomes were NED, 85.2%, persistent disease, 13.0%, recurrence, 1.9%, in the rhTSH group and NED, 87.5%, persistent or recurrent disease, 6.3% each, in the THW group (P=NS). In patients with initial stage III/IV, M0 DTC, rhTSH-aided and THW-assisted ablation were associated with comparable remnant eradication or DTC cure rates.

    In order to evaluate the significance of thyrotropin-binding inhibiting immunoglobulin (TBII) in the patients with autoimmune thyroid diseases, the authors investigated 402 cases of Graves' disease and 230 cases of Hashimoto's thyroiditis comparing 30 cases of normal healthy adult at Kyung Pook University Hospital from February 1993 to August 1994. The TBII was tested by radioimmunoassay and assessed on the dynamic change with the disease course, thyroid functional parameters, and other thyroid autoantibodies; antithyroglobulin antibody(ATAb) and antimicrosomal antibody(AMAb) including thyroglobulin. The serum level of TBII was 40.82 ± 21.651(mean ± SD)% in hyperthyroid Graves' disease and 8.89 ± 14.522% in Hashimoto's thyroiditis and both were significant different from normal control of which was 3.21 ± 2.571%. The frequency of abnormally increased TBII level was 92.2% in hyperthyroid Craves' disease, 46.7% in euthyroid Graves' disease or remission state of hyperthyroidism, and 23.9% in Hashimoto's thyroiditis. The serum levels of increased TBII in Graves' disease were positively correlated with RAIU, serum T3, T4, and FT4, but negatively correlated with serum TSH(each p<0.001). The TBII in Graves' disease had significant positive correlation with serum thyroglobulin and AMAb, but no significant correlation with ATAb. In the Hashimoto's thyroiditis, the serum levels of TBII were positively correlated with RAIU, serum T3, TSH and AMAb, but not significantly correlated with serum T4, FT4, thyroglobulin and ATAb. Therefore serum level of TBII seemed to be a useful mean of assessing the degree of hyperthyroidism in Graves' disease and correlated well with thyroidal stimulation. The serum level of TBII in Hashimoto's thyroiditis is meaningful for the degree of both functional abnormality reflecting either hyperfunction or hypofunction and the immunologic abnormality.

    Full Text Available CONTEXT: Screening programs not only offer the opportunity to trace and treat almost all cases of congenital hypothyroidism but also mean large savings to the health system. However, carefully planned strategies are necessary to extend their benefits and reduce costs. OBJECTIVE: To determine the possible influence of maternal diseases that affect maternal-fetal placenta dynamics on primary thyroid stimulating hormone (TSH screening for congenital hypothyroidism. DESIGN: Prospective non-randomized clinical trial with at least 3 months of follow-up. SETTING: A public university referral center [CAISM/Hospital das Clínicas, Faculty of Medicine, University of Campinas, Campinas, SP]. PARTICIPANTS: 415 neonates divided into 5 groups: eighty-three infants born from cardiac mothers; 98 from mothers that had toxemia; 54 of the mothers had diabetes mellitus; 40 were HIV positive and 140 had no diseases. INTERVENTION: All newborns had cord blood samples collected on filter paper at birth. MAIN MEASUREMENTS: TSH was measured from dried blood spots using a homemade immunofluorescence assay (sensitivity in dried blood spots = 0.1 mU/L. RESULTS: There was no significant difference in the mean TSH levels among the 5 groups. Moreover, TSH levels were around 5 mU/L in 48% of the newborns, indicating that our region is severely deficient in iodine. CONCLUSIONS: Our results indicate that primary TSH screening programs using cord blood are not affected by maternal diseases. We suggest that, besides its technical advantages over heel punctures with T4 primary approaches, neonatal screening using primary cord blood TSH may also be used as a monitoring tool for evaluation and control of iodine deficiency disorders (IDD.

    To verify the frequency of swallowing complaints in patients with benign nonsurgical thyroid disease and compare the self-perception of swallowing disorder intensity between different types of thyroid disease. The study sample comprised 39 women aged 19-58 years (38.54 ± 10.74) with hypothyroidism (n=22; 56.4%) or thyroid nodules (n=17; 43.6%). Presence and type of swallowing complaint and self-perception of swallowing disorder intensity were investigated by means of self-ratings recorded on a 100-millimeter visual analog scale. The data were analyzed by descriptive measures and the Mann-Whitney nonparametric test was used to compare the self-perception of swallowing disorder intensity between both clinical diagnoses of thyroid disease. The level of 5% was adopted for statistical significance. Twenty-six (66.7%) individuals reported the following swallowing complaints: pharyngolaryngeal stasis sensation (37.15%), chocking (34.29%), and odynophagia (28.57%). The mean value of self-perception of swallowing disorder intensity by the visual analog scale was 59.35 (± 27.38) millimeters. No difference in self-perception was reported between the clinical diagnoses of thyroid disease. In this sample, swallowing complaint was frequently observed in patients with benign nonsurgical thyroid disease. Moderate self-perception of swallowing disorder intensity was reported regardless of the clinical diagnosis of thyroid disease.

    Fetuses from mothers with Graves' disease may experience hypothyroidism or hyperthyroidism due to transplacental transfer of antithyroid drugs (ATD) or anti-TSH receptor antibodies, respectively. Little is known about the fetal consequences. Early diagnosis is essential to successful management. We investigated a new approach to the fetal diagnosis of thyroid dysfunction and validated the usefulness of fetal thyroid ultrasonograms. Seventy-two mothers with past or present Graves' disease and their fetuses were monitored monthly from 22 wk gestation. Fetal thyroid size and Doppler signals, and fetal bone maturation were determined on ultrasonograms, and thyroid function was evaluated at birth. Thyroid function and ATD dosage were monitored in the mothers. The 31 fetuses whose mothers were anti-TSH receptor antibody negative and took no ATDs during late pregnancy had normal test results. Of the 41 other fetuses, 30 had normal test results at 32 wk, 29 were euthyroid at birth, and one had moderate hypothyroidism on cord blood tests. In the remaining 11 fetuses, goiter was visualized by ultrasonography at 32 wk, and fetal thyroid dysfunction was diagnosed and treated; there was one death, in a late referral, and 10 good outcomes with normal or slightly altered thyroid function at birth. The sensitivity and specificity of fetal thyroid ultrasound at 32 wk for the diagnosis of clinically relevant fetal thyroid dysfunction were 92 and 100%, respectively. In pregnant women with past or current Graves' disease, ultrasonography of the fetal thyroid gland by an experienced ultrasonographer is an excellent diagnostic tool. This tool in conjunction with close teamwork among internists, endocrinologists, obstetricians, echographists, and pediatricians can ensure normal fetal thyroid function.

    Full Text Available To indicate iodine intake and the prevalence of thyroid disease in the iodine-deficient area we perform complex investigation of 2332 children and teenagers in 23 settlements of Sverdlovsk region. Studying population consisted of1153 7—8 years old children (599 girls and 554 boys and 1179 14—15 years old teenagers (637 girls and 542 boys. Study protocol includes thyroid ultrasound for all children and urinary iodine excretion for younger group and, serum TSH, AT-TG and AT-TPO in older group. The incidence of diffuse goiter was 22.8% and median of urinary iodine excretion was 53 μg/l. We found that Sverdlovsk region is a mild iodine-deficient area. The incidence of significant thyroid diseases is relatively low (thyroid cancer, functional autonomy and overt hypothyroidism — in 0.04%, nodular goiter — 0.26%, autoimmune thyroiditis with subclinical hypothyroidism — 0.6%. There is no significant difference in the prevalence of thyroid disease among children and teenagers. We found that thyroid ultrasound is not a reasonable screening strategy for thyroid cancer and nodular goiter in pediatric population of the iodine-deficient region. We consider that the most reasonable screening strategy is the palpation technique.

    The purpose of this study is the evaluation of the TCTUs in the differentiation between AIT and GD in patients with hyperthyroidism. Methods: We determined the TCTUs in 59 patients with untreated hyperthyroid GD and in 51 patients with AIT who had subclinical or manifest hyperthyroidism without medication. Patients with GD were characterized by the presence of hyperthyroidism, decreased echogenicity of the thyroid, elevation of TSH-receptor autoantibodies (TRAb). AIT was defined by a decreased echogenicity of the thyroid, absence of elevated TSH-receptor autoantibodies (TRAb), autoantibodies against the thyroid peroxidase (anti-TPO) and spontaneous remission or development of subclinical hypothyroidism within 3 months. Results: Thyroid volumes of patients with AIT were significantly lower than those of patients with GD (p 99m TcO 4 - offered rapid and reliable differentiation between hyperthyroid GD and AIT.

    To determine the prevalence of conjunctivochalasis in patients with immune thyroid diseases, to determine whether there is any association between the 2 diseases, and to determine cytologic study of conjunctivochalasis through the cytology impression test. A clinical prospective cohort study carried out by the External Diseases Department in the Ophthalmology Sector and the Thyroid Department in the Endocrinology Sector at Federal University of Sao Paulo (UNIFESP). The patients included were divided into 2 groups following these inclusion criteria: a control group of 25 patients without thyroid diseases, confirmed after clinical and laboratory examinations (thyroid hormones), or any other ocular diseases. The study group consisted of 31 patients with thyroid diseases, the diagnosis of which was confirmed by the Endocrinology Sector. The thyroidopathies included were autoimmune diseases but excluded nonautoimmune diseases. A protocol endorsed by the UNIFESP was followed, using clinical and ophthalmological history, biomicroscopy, and impression cytology. Fifty-two percent of patients without thyroid diseases and 88% of patients with thyroid diseases presented with conjunctivochalasis. The risk ratio was 1.705 (Pr > chi(2) = 0.0038), indicating that there is an association between them. For the impression cytology in inferior bulbar conjunctiva, there was an association between the result of the impression cytology and conjunctivochalasis (Pearson chi(2) = 10.1190 Pr = 0.006). The prevalence of conjunctivochalasis in patients with autoimmune thyroid diseases was 88%. Patients with autoimmune thyroidopathy presented higher percentages of conjunctivochalasis than the control group, confirming the association between them. The cytologic study showed the highest prevalence of abnormal surface features in eyes with conjunctivochalasis.

    Technetium-99m (Tc-99m) thyroid scintigraphy is a well known diagnostic tool that shows the entire gland in a single image. We aimed to evaluate its additive diagnostic value in subclinical autoimmune thyroid disease (S-AITD) in systemic lupus erythematosus (SLE) patients. We investigated 100 systemic lupus erythematosus (SLE) patients without overt thyroid involvement (eight men and 92 women; mean age 40±6.5 years) and 50 age and sex matched controls. All were subjected to thyroid evaluation using anti-thyroglobulin (anti-TG) and anti-thyroid peroxidase (anti-TPO) antibodies; hormones (FT3; FT4 and TSH) and Tc-99m thyroid scintigraphy. 14/100 (14%) and none (0%) were positive for S-AITD in SLE and control groups, respectively (P = 0.0001). They were classified by thyroid scintigraphy and hormonal profile into 2/14 Hashimoto; 10/14 atrophic thyroiditis and 2/14 Graves' disease. Anti-TPO was elevated in 12 SLE cases, while anti-TG was elevated in only 2/14 (P = 0.0001). Thyroid scintigraphy showed statistically significant associations with FT4, TSH and anti-TPO. Tc-99m thyroid scintigraphy may have an additional diagnostic role in S-AITD among SLE patients, with an impact on patient management. This potential needs to be further evaluated in a larger series on a multicenter basis. © The Author(s) 2015.

    Thyroid nodules are frequently found in association with Graves' disease. Papillary carcinoma can arise from these nodules. We report a 65-year-old gentleman who presented with classical features of Graves disease. Technetium 99 scintigraphy revealed diffuse goiter with a cold nodule over the isthmus. Papillary thyroid cancer was suggested by the enlarging thyroid gland, and by the presence of cold nodule, and was proven by fine needle aspiration biopsy of this nodule. The diagnosis was confirmed by histopathology of thyroid specimen after total thyroidectomy, which also showed local invasion; metastatic work up revealed pulmonary and liver metastasis. Despite treatment by total thyroidectomy, twice radioactive iodine I131 ablation and levothyroxine replacement in a thyroid stimulating hormone suppressive dose, he still harbors metastases with elevated thyroglobulin level. This case should raise the index of suspicion of the treating physician to consider similar association, and to prompt early diagnosis and surgical treatment to prevent dreadful consequences that might adversely affect the outcome.

    Thyroid dysfunction is a common disorder in daily clinical practice, however due to unspecific and diverse symptoms of the disease, it is sometimes hard to make a definite diagnosis. Japan thyroid association (JTA) published 'Guideline for the diagnosis of thyroid disease, 2010' and it is open to the public on the JTA website(http : //www.japanthyroid.jp/doctor/ guideline/japanese.html). English version of the guideline is also available. JTA also published 'Guideline for the management of subclinical hypothyroidism 2008' and 'Guideline for the diagnosis of thyroid storm, version 2'. The latter in English version has been published in Thyroid(http : //www.ncbi.nlm.nih.gov/pubmed/22494618). The utility of these guidelines is discussed.

    ). HT is primarily a T-cell mediated disease, and whether B cells play a pathogenic role in the pathogenesis is still unclear. Both GD and HT are characterized by infiltration of the thyroid gland by self-reactive T cells and B cells. In the first paper of this thesis, the role of regulatory B cells...... (Bregs) and regulatory T cells (Tregs) were investigated in the context of GD and HT. First, we studied the role of the thyroid self-antigen, thyroglobulin (TG) in healthy donors. The self-antigen TG, but not the foreign recall antigen tetanus toxoid (TT), was able to induce interleukin 10 (IL-10......Autoimmune diseases occur due to faulty self-tolerance. Graves' disease (GD) and Hashimoto's thyroiditis (HT) are classic examples of organ-specific autoimmune diseases. GD is an auto-antibody-mediated disease where autoantibodies are produced against the thyroid stimulating hormone receptor (TSHR...

    Many details concerning the interventional diagnosis and therapy of thyroid disease need to be studied deeply and carefully; for example, the thyroid applied anatomy, especially the anatomical imageology study of the thyroid arterial anastomosis involving the therapeutic effects and complications, the thyroid artery embolization treatment, presently as a substitution or the supplement therapy for the traditional classical therapy of Graves disease. There are many exploration to extend the indication scope, the therapeutic effect, embolization scope in intervention for Graves disease due to having no accurate individual quantification standard, and so on. The thyroid arterial embolization for Graves disease is to reduce the main cause of thyroxin secretion. Simultaneously, the comprehensive therapeutic effects might have possibly produce the thyroidcytic apoptosis and immune adjustments. Serious complications such as the cerebral infarction, the hyperthyroidism crisis, the hypocalcemia, the periodic paralysis, and so on commonly occured in thyroid arterial embolization. It is necessary to keep strictly the procedure rule and the indication. The mid-and long- term therapeutic effect of thyroid artery embolization for Graves disease is good, but still need more extensive and prudent research for the prospective achievement. (authors)

  7. Thyroid storm associated with Graves' disease covered by diabetic ketoacidosis: A case report

    Full Text Available Abstract Background Thyroid storm is a condition in which multiple organ dysfunction results from failure of the compensatory mechanisms of the body owing to excessive thyroid hormone activity induced by some factors in patients with thyrotoxicosis. While diabetic ketoacidosis (DKA is an important trigger for thyroid storm, simultaneous development of DKA and thyroid storm is rare. Case presentation A 59-year-old woman with no history of either diabetes mellitus or thyroid disease presented to our hospital because of developing nausea, vomiting and diarrhea for 2 days. Physical examination showed mild disturbance of consciousness, fever, and tachycardia. There were no other signs of thyrotoxicosis. Laboratory studies revealed elevation of random blood glucose and glycosylated hemoglobin, strongly positive of urine acetone, and metabolic acidosis. Since DKA was diagnosed, we initiated the patient on treatment with administration of insulin and adequate fluid replacement. Although the hyperglycemia and acidosis were immediately relieved, the disturbance of consciousness and tachycardia remained persistent. Levels of FT3 and FT4 were extremely high and TSH was below the detectable limit. TRAb was positive. The thyroid storm score of Burch & Wartofsky was 75/140, and the thyroid storm diagnostic criteria of the Japan Thyroid Association were satisfied. Oral administration of thiamazole, potassium iodide and propranolol resulted in immediate relief of the tachycardia. Discussion We encountered a case of thyroid storm associated with Graves' disease covered by DKA. Thyroid storm and DKA are both potentially fatal, and the prognosis varies depending on whether or not these conditions are detected and treated sufficiently early. The thyroid storm diagnostic criteria prepared in 2008 by the Japan Thyroid Association are very simple as compared to the Burch & Wartofsky scoring system for thyroid storm. The Japanese criteria may be useful in the diagnosis

    Purpose of Review Hypothyroidism is highly prevalent in chronic kidney disease (CKD) patients, including those receiving dialysis. This review examines potential mechanistic links between thyroid and kidney disease; current evidence for hypothyroidism as a risk factor for de novo CKD and CKD progression; and studies of thyroid functional disorders, cardiovascular disease, and death in the CKD population. Recent Findings Epidemiologic data have demonstrated an incrementally higher prevalence of hypothyroidism with increasing severity of kidney dysfunction. Various thyroid functional test abnormalities are also commonly observed in CKD, due to alterations in thyroid hormone synthesis, metabolism, and regulation. While the mechanistic link between thyroid and kidney disease remains unclear, observational studies suggest hypothyroidism is associated with abnormal kidney structure and function. Previously thought to be a physiologic adaptation, recent studies show that hypothyroidism is associated with higher risk of cardiovascular disease and death in CKD. Summary A growing body of evidence suggests that hypothyroidism is a risk factor for incident CKD, CKD progression, and higher death risk in kidney disease patients. Rigorous studies are needed to determine impact of thyroid hormone replacement upon kidney disease progression, cardiovascular disease, and mortality, which may shed light into the causal implications of hypothyroidism in CKD.

    Thyroid dysfunction can develop in patients with Hodgkin`s disease who are treated with mantle irradiation. During the period 1970-89, the records of 320 patients who received mantle irradiation and who had thyroid function tests (TFT) were retrospectively reviewed. The median age was 30 years (range, 7-69 years). The median mantle and thyroid dose was 36 Gy (range, 30-40 Gy) and 39.8 Gy (range, 32-65 Gy), respectively. Overall thyroid dysfunction was present in 39% of the patients. Clinical hypothyroidism was seen in 10% and biochemical hypothyroidism was noted in 25%. Hyperthyroidism was found in 4% of patients. Thyroid nodules had developed in six patients (2%), of which those in four patients were malignant. Age, sex, histological subtype, stage of disease, dose, Iymphangiogram and treatment with chemotherapy were not significant factors in the development of thyroid dysfunction. The narrow dose range prevented adequate analysis of dose effect. The results indicate that the incidence of thyroid abnormalities is high enough to warrant regular TFT assessment with pre-irradiation levels and follow-up testing for life because the development of abnormalities can occur many years later. Thyroid examination should form part of the routine follow-up examination and any abnormality should be promptly investigated. Copyright (1998) Blackwell Science Pty Ltd 32 refs., 3 tabs.

    Assessment of disease severity for patients with hyperthyroidism involves clinical evaluation and laboratory testing. To determine if there is a correlation between symptoms and thyroid function test results, we prospectively studied hyperthyroid patients using a standardized symptom rating scale and serum thyroid function parameters. We examined 25 patients with untreated, newly diagnosed Graves' disease using the Hyperthyroid Symptom Scale (HSS) and serum levels of thyroxine (T4), triiodothyronine (T3) relative insulin area (RIA), and estimates of free thyroxine index (FTI). In addition, we compared thyroid hormone levels with standard measures of depression and anxiety in these patients. When regression analyses controlling for age were performed, none of these symptom ratings were associated with FTI or T3 RIA. The HSS was correlated with goiter size and anxiety ratings and was inversely correlated with age. The present study suggests that there is no relationship between the clinical assessment of disease severity and serum levels of thyroid hormone in untreated Graves' disease.

    There is a relationship between thyroid diseases and primary and secondary changes in haemostasis. The most frequent association between them are hypocoagulability states with clinical hypothyroidism and vascular thrombophilia (hypercoagulability and/or hypofibrinolysis) with hyperparathyroidism. However, there are recent studies that have detected changes in haemostasis -primary and secondary- associated with thyroid diseases with normal hormone levels, suggesting other pathogenic mechanisms not yet known. The cases are presented of 2 patients with thyroid disease that required surgery: one multinodular goitre and one papillary carcinoma of the thyroid, both with normal hormone levels. They were shown to have haemostasis disorders during the preoperative work up. These showed a Factor VII deficiency and a Factor XI deficiency along with a thrombotic disease of unknown origin, respectively.

    Benign thyroid disease ranks by far as the most frequent therapy in nuclear medicine. In Germany approximately 25 000 cases of hyperthyreosis are being treated in association with autonomy or Graves' disease, but also for the reduction of goiters or the correction of latent functional disturbances. In such indications radiotherapy is virtually free of risk as opposed to surgery and ranks more favorable in regard to costs and curative effects versus pharmacological long term treatment. Still regional varying therapeutical concepts and intentions are being pursued and trials of improvements described. There is consent in therapy that quality of treatment is closely linked to a specialized out-door platient preparation, individual hospital activity dosage and lifelong follow up including continued evaluation of therapeutical results. In this paper minimal requirements of outpatient measures before and after therapy are summarized which in Germany is only permitted on an inhospital patient basis. Considering basics of radioactive preventive law, scientific evidence of available results of therapeutical studies and a survey of German therapeutic centers, suggestions for a quality maintaining management in view of the most effective utilization for the limited available number of beds is presented for discussion.

    Full Text Available Background: Steroid replacement without thyroxine supplementation normalizes thyroid function test (TFT in some but not all Addison's disease patients with primary hypothyroidism. Both autoimmune and nonautoimmune mechanisms contribute to this improvement in TFT. However, the documentation of the change in thyroid autoimmunity after cortisol replacement is very limited in the literature. The aim of this study was to determine the effect of steroid replacement on TFT and anti-thyroid peroxidase antibody (anti-TPO-Ab titer in Addison's disease with primary hypothyroidism. Materials and Methods: This observational study was conducted in a tertiary care center in South India. Six Addison's disease patients with primary hypothyroidism, who were only on steroid replacement, were included in the study. Low serum cortisol (22 pmol/L and/or hyperpigmentation of skin/mucous membranes was considered as the diagnostic criteria for Addison's disease. Primary hypothyroidism (both overt and subclinical was defined as high thyroid stimulating hormone (TSH with/without low free thyroxine (fT4. TFT and anti-TPO-Ab were performed before and after steroid replacement in all of them. Results: Poststeroid replacement, there was a normalization of TSH in all but one subjects. In overt hypothyroidism patients, fT4 also normalized. The improvement in TFT was not associated with decreasing titer of the anti-TPO-Ab in all six patients. However, there was a significant difference in TSH after steroid replacement compared to the baseline status. Conclusions: The concept of normalization of primary hypothyroidism with cortisol replacement in patients with Addison's disease should be recognized to avoid iatrogenic thyrotoxicosis caused by thyroxine replacement. Both autoimmune and nonautoimmune mechanisms contribute to these alterations.

    Full Text Available Abstract Severe pulmonary hypertension is a lethal group of disorders which preferentially afflicts women. It appears that in recent years the patient profile has shifted towards older, obese, and postmenopausal women, suggesting that endocrine factors may be important. Several studies have revealed an increased prevalence of thyroid disease in these patients, but no studies have evaluated for a coexistence of endocrine factors. In particular, no studies have attempted to evaluate for concurrent thyroid disease, obesity and long-term estrogen exposure in patients. 88 patients attending the Pulmonary Hypertension Association 8th International meeting completed a questionnaire and were interviewed. Information was collected regarding reproductive history, height, weight, and previous diagnosis of thyroid disease. 46% met criteria for obesity. 41% reported a diagnosis of thyroid disease. 81% of women reported prior use of hormone therapy. 70% reported greater than 10 years of exogenous hormone use. 74% of female patients reported two or more of potentially disease modifying endocrine factors (obesity, thyroid disease or estrogen therapy. The coexistent high prevalence in our cohort of exogenous estrogen exposure, thyroid disease and obesity suggests that an interaction of multiple endocrine factors might contribute to the pathogenesis of pulmonary hypertension and may represent epigenetic modifiers in genetically-susceptible individuals.

    Abstract Background The encephalopathy associated with autoimmune thyroid disease (EAATD) is characterized by neurological\\/psychiatric symptoms, high levels of anti-thyroid antibodies, increased cerebrospinal fluid protein concentration, non-specific electroencephalogram abnormalities, and responsiveness to the corticosteroid treatment in patients with an autoimmune thyroid disease. Almost all EAATD patients are affected by Hashimoto\\'s thyroiditis (HT), although fourteen EAATD patients with Graves\\' disease (GD) have been also reported. Methods We have recorded and analyzed the clinical, biological, radiological, and electrophysiological findings and the data on the therapeutic management of all GD patients with EAATD reported so far as well as the clinical outcomes in those followed-up in the long term. Results Twelve of the fourteen patients with EAATD and GD were women. The majority of GD patients with EAATD presented with mild hyperthyroidism at EAATD onset or shortly before it. Active anti-thyroid autoimmunity was detected in all cases. Most of the patients dramatically responded to corticosteroids. The long term clinical outcome was benign but EAATD can relapse, especially at the time of corticosteroid dose tapering or withdrawal. GD and HT patients with EAATD present with a similar clinical, biological, radiological, and electrophysiological picture and require an unaffected EAATD management. Conclusions GD and HT equally represent the possible background condition for the development of EAATD, which should be considered in the differential diagnosis of all patients with encephalopathy of unknown origin and an autoimmune thyroid disease, regardless of the nature of the underlying autoimmune thyroid disease.

    We investigated the biokinetics of {sup 99m}Tc-sestamibi in the thyroid of euthyroid volunteers (EVs) and in patients with autoimmune thyroid diseases and determined the best time interval between {sup 99m}Tc-sestamibi injection and calculation of uptake. Forty EVs, 30 patients with Graves' disease (GD), 15 patients with atrophic Hashimoto's thyroiditis (AHT) and 15 patients with hypertrophic Hashimoto's thyroiditis (HHT) underwent {sup 99m}Tc-sestamibi thyroid scintigraphy. Dynamic images were acquired for 20 min, and static images were obtained 20 min, 60 min and 120 min post injection. Five-, 20-, 60- and 120-min uptake, time to maximal uptake (T{sub max}) and T{sub 1/2} of tracer clearance were calculated. Thyroid hormones and antibodies were measured. {sup 99m}Tc-pertechnetate uptake was investigated in GD patients. T{sub max} was approximately 5 min in all four groups. The mean T{sub 1/2} value for EVs was similar to the GD value and lower than the HHT and AHT values. The mean ({+-}SD) 5-min uptake was 0.13% ({+-}0.05%) for EVs. The 5-min uptake in GD was higher than that in EVs(P<0.001) and correlated with free thyroxine (r=0.54) and with {sup 99m}Tc-pertechnetate uptake (r=0.68). Uptake in HHT was higher than that in AHT (P=0.0003) and EVs (P=0.002). Uptake in AHT was lower than uptake in EVs (P=0.0001). Five minutes is the optimal time interval between {sup 99m}Tc-sestamibi injection and calculation of thyroid uptake. Five-minute uptake differentiates euthyroid individuals from GD patients. There is a high correlation between {sup 99m}Tc-sestamibi and {sup 99m}Tc-pertechnetate uptake in GD. The reduced {sup 99m}Tc-sestamibi uptake in AHT patients is probably due to glandular destruction and fibrosis. Inflammatory infiltrate and high mitochondrial density in thyrocytes possibly explain the increased uptake in GD and HHT. (orig.)

    Radioiodine (RAI) is a cornerstone in the treatment of Differentiated Thyroid Cancer (DTC). In patients on haemodialysis due to End-Stage Renal Disease (ESRD), it must be used cautiously, considering the renal clearance of this radionuclide. Also, the safety of the procedure and subsequent long-term outcome is still not well defined. In 2001, we described a dosimetric method and short-term results in three patients, with a good safety profile. We hypothesize that our method is safe in a long-term scenario without compromising the prognosis of both renal and thyroid disease. Descriptive-retrospective study. A systematic search was carried out using our clinical database from 2000 to 2014. DTC and radioiodine treatment while on haemodialysis. peritoneal dialysis. Final sample n=9 patients (n=5 males), age 48 years (median age 51 years males, 67 years female group); n=8 papillary thyroid cancer, n=1 follicular thyroid cancer; n=5 lymph node invasion; n=1 metastatic disease. Median RAI dose administered on haemodialysis 100mCi. 7.5 years after radioiodine treatment on haemodialysis, n=7 deemed free of thyroid disease, n=1 persistent non-localised disease. No complications related to the procedure or other target organs were registered. After 3.25 years, n=4 patients underwent successful renal transplantation; n=4 patients did not meet transplantation criteria due to other conditions unrelated to the thyroid disease or its treatment. One patient died due to ischemic cardiomyopathy (free of thyroid disease). Radioiodine treatment during haemodialysis is a long-term, safe procedure without worsening prognosis of either renal or thyroid disease. Copyright © 2015 Elsevier España, S.L.U. and SEMNIM.

    Full Text Available CONTEXT AND OBJECTIVE: Celiac disease is an autoimmune disorder with an average prevalence of 1% in Europe and the United States. Because of strong European ancestry in southern Brazil, this study aimed to evaluate the seroprevalence of celiac disease among autoimmune thyroiditis patients.DESIGN AND SETTING: Cross-sectional study in a public university hospital.METHODS: This cross-sectional prevalence study included autoimmune thyroiditis patients who were tested for anti-endomysial and anti-transglutaminase antibodies between August 2010 and July 2011.RESULTS: Fifty-three patients with autoimmune thyroiditis were included; 92.5% were women, with mean age of 49.0 ± 13.5 years. Five patients (9.3% were serologically positive for celiac disease: three of them (5.6% were reactive for anti-endomysial antibodies and two (3.7% for anti-transglutaminase. None of them exhibited anemia and one presented diarrhea. Endoscopy was performed on two patients: one with normal histology and the other with lymphocytic infiltrate and villous atrophy.CONCLUSION: The prevalence of celiac disease among patients with autoimmune thyroid disease was 9.3%; one patient complained of diarrhea and none presented anemia. Among at-risk populations, like autoimmune thyroiditis patients, the presence of diarrhea or anemia should not be used as a criterion for indicating celiac disease investigation. This must be done for all autoimmune thyroiditis patients because of its high prevalence.

    Osteoporosis is a systemic skeletal disease characterized by low bone mass and microarchitectural deterioration of bone tissue, leading to enhanced bone fragility and a consequent increase in fracture risk. One of the leading causes of secondary osteoporosis are thyroid diseases; this fact carries special importance for Georgia because of thyroid disease prevalence in Georgian population. In the present article we discuss the mechanisms, by which thyroid hormones and thyroid stimulating hormone (TSH) act on bone. We also present the data of meta-analysis of large studies, which demonstrate the complex relationship between the thyroid diseases and bone mineral density as well as the fracture risk; namely by overt and subclinical thyrotoxicosis, hypothyroidism and the treatment with the suppressive doses of levothyroxine. Beside that, we review the related data and the possible reasons, why different treatment regimens of Grave's disease: conservative, operative and radioiodine are related to different fracture risks. Finally, we discuss briefly the practical aspects of the treatment of secondary osteoporosis, related with thyroid diseases.

    Calculation of effective thyroidal half-life (Teff) of iodine-131( 131 I) is cumbersome and tedious. The aim of this study was to investigate factors that could be used to predict Teff and to develop a Teff prediction model in Graves' disease patients. A total of 256 patients with GD were involved in this study. We investigated the influences of age, gender, disease duration, thyroid weight, antithyroid drugs, antithyroid drugs discontinuation period (ADP), thyroid function indexes, thyroid autoantibodies, thyroid-stimulating hormone receptor antibody (TRAb) level and radioactive iodine uptake (RAIU) values before 131 I therapy on Teff, applying univariate and multivariate analyses. Teff correlated negatively with thyroid peroxidase antibody, TRAb and thyroid weight, as well as positively with 24-hour, 48-hour, and 72-hour RAIU. Additionally, a longer ADP (especially≥ 14d) or without antithyroid drugs before 131 I therapy led to a longer Teff. Stepwise multiple linear regression analysis showed that 24-hour and 72-hour RAIU were statistically significant predictors of Teff ( P Graves' disease, with high prediction accuracy.

    Subclinical thyroid dysfunction is very common in clinical practice and there is some evidence that it may be associated with cardiovascular disease. The aim here was to evaluate the frequencies of subclinical thyroid disease and risk factors for cardiovascular disease among women at a workplace, and to evaluate the association between subclinical thyroid disease and cardiovascular risk factors among them. Cross-sectional study on 314 women aged 40 years or over who were working at Universidade de São Paulo (USP). All the women answered a questionnaire on sociodemographic characteristics and risk factors for cardiovascular disease and the Rose angina questionnaire. Anthropometric variables were measured and blood samples were analyzed for blood glucose, total cholesterol and fractions, high-sensitivity C-reactive protein, thyroid-stimulating hormone (TSH), free thyroxine (free-T4) and anti-thyroperoxidase antibodies (anti-TPO). The frequencies of subclinical hypothyroidism and hyperthyroidism were, respectively, 7.3% and 5.1%. Women with subclinical thyroid disease presented higher levels of anti-TPO than did women with normal thyroid function (P = 0.01). There were no differences in sociodemographic factors and cardiovascular risk factors according to thyroid function status, except for greater sedentarism among the women with subclinical hypothyroidism. Restricting the comparison to women with subclinical hypothyroidism (TSH > 10 mIU/l) did not change the results. In this sample of women, there was no association between poor profile of cardiovascular risk factors and presence of subclinical thyroid disease that would justify screening at the workplace.

    Nitrate is a contaminant of drinking water in agricultural areas and is found at high levels in some vegetables. Nitrate competes with uptake of iodide by the thyroid, thus potentially affecting thyroid function. We investigated the association of nitrate intake from public water supplies and diet with the risk of thyroid cancer and self-reported hypothyroidism and hyperthyroidism in a cohort of 21,977 older women in Iowa who were enrolled in 1986 and who had used the same water supply for >10 years. We estimated nitrate ingestion from drinking water using a public database of nitrate measurements (1955-1988). Dietary nitrate intake was estimated using a food frequency questionnaire and levels from the published literature. Cancer incidence was determined through 2004. We found an increased risk of thyroid cancer with higher average nitrate levels in public water supplies and with longer consumption of water exceeding 5 mg/L nitrate-N (for >or=5 years at >5 mg/L, relative risk [RR] = 2.6 [95% confidence interval (CI) = 1.1-6.2]). We observed no association with prevalence of hypothyroidism or hyperthyroidism. Increasing intake of dietary nitrate was associated with an increased risk of thyroid cancer (highest vs. lowest quartile, RR = 2.9 [1.0-8.1]; P for trend = 0.046) and with the prevalence of hypothyroidism (odds ratio = 1.2 [95% CI = 1.1-1.4]), but not hyperthyroidism. Nitrate may play a role in the etiology of thyroid cancer and warrants further study.

    Full Text Available Background/Aim. To evaluate the efficacy of methotrexate for the treatment of thyroid eye disease (TED. Methods. 36 consecutive patients with active TED, previously treated with corticosteroids but stopped due to the occurrence of side effects, were commenced on methotrexate therapy. Two different weekly doses were administered depending on the weight of the patient (7.5 mg or 10 mg. Clinical activity score (7-CAS, visual acuity (VA, ocular motility, exophthalmos, and eyelid position were retrospectively evaluated at 3, 6, and 12 months and compared with baseline data. Results. There was a statistically significant improvement in 7-CAS at 3, 6, and 12 months after treatment (P<0.0001. There was no significant change in visual acuity. Ocular motility disturbances improved at 6 and 12 months (P<0.001. There was no significant change in exophthalmos (mean 24 mm, SD 3 mm or eyelid position (marginal reflex distance mean 6 mm, SD 1.5 mm during the follow-up period. No side effects were registered. Conclusions. Methotrexate therapy is effective in reducing CAS and ocular motility disturbances. No significant improvement in proptosis or eyelid retraction should be expected from this treatment. Eventually, it might be considered a suitable alternative treatment in TED for patients who cannot tolerate steroids.

    The goal of this work is the quantification of therapy results of a radioiodine therapy with Iodine 131 on 367 patients with the following benign thyroid diseases: euthyroidal struma, hyperthyroidism, hyperthyroidal struma and autonomous adenoma. 1. Euthyroidal struma - subjective improvement and objective diminution of the struma by 63%, subjective or objective improvement by 21% of the patients. Including the probable successful therapies the success rate was all together 90.1%. 2. Hyperthyroidism - after one-time/more-time (18.6%) radioiodine therapy the success rate was 71.5/85.7% including latent (8.6/10.0%) and manifest (7.1/8.5%) hypothroidism. 3. Hyperthyroidal struma - after one-time/more-time (16.9%) radioiodine therapy the success rate was 74.7/90.1% including latent (-/5.7%) and manifest (1.4/2.8%) hypothyroidism. 4. Autonomous adenoma - after one-time/two-time (5.2%) radioiodine therapy the success rate was 80.5/84.6% including 15.5% latent hypothyroidism. The results will be discussed in comparison to published data and to operation and thyrostatic treatment. (TRV) [de

  12. Clinical Relevance of Environmental Factors in the Pathogenesis of Autoimmune Thyroid Disease

    Full Text Available Genetic factors contribute for about 70% to 80% and environmental factors for about 20% to 30% to the pathogenesis of autoimmune thyroid disease (AITD. Relatives of AITD patients carry a risk to contract AITD themselves. The 5-year risk can be quantified by the so-called Thyroid Events Amsterdam-score, based on serum thyroid-stimulating hormone, thyroid peroxidase (TPO-antibodies and family history. Subjects at risk may ask what they can do to prevent development of AITD. This review summarizes what is known about modulation of exposure to environmental factors in terms of AITD prevention. To stop smoking decreases the risk on Graves disease but increases the risk on Hashimoto disease. Moderate alcohol intake provides some protection against both Graves and Hashimoto disease. Low selenium intake is associated with a higher prevalence of thyroid autoimmunity, but evidence that selenium supplementation may lower TPO antibodies and prevent subclinical hypothyroidism remains inconclusive. Low serum vitamin D levels are associated with a higher prevalence of TPO antibodies, but intervention studies with extra vitamin D have not been done yet. Stress may provoke Graves hyperthyroidism but not Hashimoto thyroiditis. Estrogen use have been linked to a lower prevalence of Graves disease. The postpartum period is associated with an increased risk of AITD. Taking together, preventive interventions to diminish the risk of AITD are few, not always feasible, and probably of limited efficacy.

    Purpose: While the literature supports the use of radiation therapy for thyroid eye disease, it does not sufficiently describe in detail the results of radiation therapy for optic neuropathy associated with thyroid eye disease. The objective of this study is to quantify the changes in parameters of optic neuropathy after orbital irradiation for thyroid eye disease. Methods and Materials: Twelve consecutive patients with optic neuropathy from thyroid eye disease were followed by a single neuro-ophthalmology practice and treated by one radiation oncologist with radiation therapy from 1991 through 1995. All cases were prospectively followed for visual acuity, color vision, mean deviation, and/or foveal sensitivity and afferent pupillary defect. All patients received 2000 cGy in 10 fractions with megavoltage irradiation to the orbits. Results: Ten of 12 patients were evaluated for follow-up (one moved out of this country and one had a stroke, which confounded interpretation of examination results). An analysis was performed retrospectively while treatment and evaluation remained uniform. Five men and five women formed the basis of this study with a median age of 60 years (35-76 years). Nineteen eyes were evaluated for thyroid optic neuropathy. Improvement in optic nerve function occurred in eight of ten patients. Improvement was seen either during radiotherapy or within 2 weeks of completion. No long-term adverse effects were noted. Conclusion: This study objectively demonstrates improvement in optic neuropathy from radiation therapy for thyroid eye disease

    Full Text Available The prevalence of celiac disease autoimmunity or tissue transglutaminase autoantibodies (TGA amongst patients with type 1 diabetes (T1D and autoimmune thyroid disease (AITD in the Chinese population remains unknown. This study examined the rate of celiac disease autoimmunity amongst patients with T1D and AITD in the Chinese population. The study included 178 patients with type 1 diabetes and 119 with AITD where 36 had both T1D and AITD, classified as autoimmune polyglandular syndrome type 3 variant (APS3v. The study also included 145 patients with type 2 diabetes (T2D, 97 patients with non-autoimmune thyroid disease (NAITD, and 102 healthy controls. Serum islet autoantibodies, thyroid autoantibodies and TGA were measured by radioimmunoassay. TGA positivity was found in 22% of patients with either type 1 diabetes or AITD, much higher than that in patients with T2D (3.4%; p< 0.0001 or NAITD (3.1%; P < 0.0001 or healthy controls (1%; p<0.0001. The patients with APS3v having both T1D and AITD were 36% positive for TGA, significantly higher than patients with T1D alone (p = 0.040 or with AITD alone (p = 0.017. T1D and AITD were found to have a 20% and 30% frequency of overlap respectively at diagnosis. In conclusion, TGA positivity was high in the Chinese population having existing T1D and/or AITD, and even higher when both diseases were present. Routine TGA screening in patients with T1D or AITD will be important to early identify celiac disease autoimmunity for better clinical care of patients.

    The aim of the study was to evaluate systematic thyroid ultrasonography (US) relevance in newly diagnosed Graves' disease among patients presenting without palpable nodules. We consecutively recruited 208 cases of Graves' disease without palpable nodule. All patients were screened for thyroid antibodies and underwent a thyroid US. Ultrasonically guided biopsy was proposed for the assessment of all nodules upper or equal to 10mm in diameter. Two third of patients had an abnormal thyroid at palpation requiring an US. One third of patients had a normal thyroid at palpation and US was consequently unwarranted. Among all patients, US detected non-palpable nodules in 26% of cases. We found no smears suspected to be cancerous. In newly diagnosed Graves' disease, the US relevance is only questionable in patients without abnormal thyroid at palpation. Ultrasonography detected non-palpable nodules and none was suspected to be cancerous. These data suggest that US is not useful in patients without abnormal thyroid at palpation. Nevertheless, the recent Thyroid Imaging-Reporting And Data System classification (TI-RADS) might change our conclusions. The TI-RADS classification indeed improves the selection of nodules lower than 10mm in diameter requiring a biopsy. Nodules lower than 10mm in diameter were not biopsied in the present study. The other US data presented herein (echogenicity, vascularisation) provide no further relevance for systematic US in newly diagnosed patients. Copyright © 2014 Elsevier Masson SAS.

    Ectopic thyroid of thyroid ectopia is a rare developmental anomaly with the prevalence of 1 per 100,000 300,000 population. Even rarer, such an anomaly manifests as dual thyroid ectopia. To our best knowledge, only one case has been reported on dual thyroid ectopia with graves' disease in the Eglish literature. We present here a case of dual thyroid ectopia complicated by graves' disease, where by the diagnosis was rendered through judicious use of various diagnostic modalities coupled with a close clinical follow up. In this case, therapeutic consideration should be personalized with proper informed consent of the patient.

    The purpose of this study is the evaluation of the TCTUs in the differentiation between AIT and GD in patients with hyperthyroidism. Methods: We determined the TCTUs in 59 patients with untreated hyperthyroid GD and in 51 patients with AIT who had subclinical or manifest hyperthyroidism without medication. Patients with GD were characterized by the presence of hyperthyroidism, decreased echogenicity of the thyroid, elevation of TSH-receptor autoantibodies (TRAb). AIT was defined by a decreased echogenicity of the thyroid, absence of elevated TSH-receptor autoantibodies (TRAb), autoantibodies against the thyroid peroxidase (anti-TPO) and spontaneous remission or development of subclinical hypothyroidism within 3 months. Results: Thyroid volumes of patients with AIT were significantly lower than those of patients with GD (p<0.05). TRAb levels were significantly higher in GD-patients (median: 19.5 U/ml; range: 15.3-35 U/ml) than in AIT-patients (median: 1.3 U/ml; range: 0-4.1 U/ml). 73% (38/59) of patients with GD had elevated anti-TPO levels. In these patients anti-TPO levels (median: 768 U/l; range: 83-6397 U/l) were not significantly different from anti-TPO levels of patients with AIT (median: 834 U/l; range: 107-8675 U/l; p=0.17). TCTUs values of patients with AIT were significantly lower (p<0.05; median: 0.9%; range: 0.1-3.2%) than those of patients with GD (median: 5.7%; range: 1.9-28.3%). Conclusion: In our patients quantitative thyroid scintigraphy with {sup 99m}TcO{sub 4}{sup -} offered rapid and reliable differentiation between hyperthyroid GD and AIT. (orig.)

    Autoimmune thyroid diseases, including Graves' and Hashimoto's thyroiditis, are the most frequent autoimmune disorders. Viral infection, including Epstein-Barr virus (EBV), is one of the most frequently considered environmental factors involved in autoimmunity. Its role in the development of AITD has not been confirmed so far. Surgical specimens of Graves' and Hashimoto's diseases and nodular goitres were included in the study. The expression of EBV latent membrane protein 1 (LMP1) was analysed by immunohistochemistry, with the parallel detection of virus-encoded small nuclear non-polyadenylated RNAs (EBER) by in situ hybridisation. In none of the Graves' disease specimens but in 34.5% of Hashimoto's thyroiditis cases the cytoplasmic expression of LMP1 was detected in follicular epithelial cells and in infiltrating lymphocytes. EBER nuclear expression was detected in 80.7% of Hashimoto's thyroiditis cases and 62.5% of Graves' disease cases, with positive correlation between LMP1 and EBER positivity in all Hashimoto's thyroiditis LMP1-positive cases. We assume that high prevalence of EBV infection in cases of Hashimoto's and Graves' diseases imply a potential aetiological role of EBV in autoimmune thyroiditis. The initiation of autoimmune thyroiditis could start with EBV latency type III infection of follicular epithelium characterised by LMP1 expression involving the production of inflammatory mediators leading to recruitment of lymphocytes. The EBV positivity of the infiltrating lymphocytes could be only the presentation of a carrier state, but in cases with EBER+/ LMP1+ lymphocytes (transforming latent infection) it could represent a negative prognostic marker pointing to a higher risk of primary thyroid lymphoma development.

    To evaluate the diagnostic accuracy of the measurement of free thyroxine(FT4) by radioimmunoassay, we measured free T 4 and T 4 , T 3 , T 3 RU, TSH and TBG serum levels by radioimmunoassay in 18 healthy persons and 52 patients with various thyroid diseases and 11 normal pregnant women. The results are as follows. 1) In 19 cases of overt hyperthyroidism, T 3 , free T 4 and FTI, T 4 /TBG ratio reflect hyperfunction in all cases. T 4 is increased in 94%(18/19) and TBG and TSH are decreased in 79%(15/19). 2) In 8 patients with overt hypothyroidism, TSH is increased in all cases and free T 4 and FTI is decreased in all cases. T 4 is decreased in 87.5%(7/8), T 3 is decreased in 75%(6/8) and T 4 /TBG ratio is decreased in 62.5%(5/8). 3) In 5 patients who are clinically in euthyroid state after treatment of hyperthyroidism, T , 4 free T 4 , FTI and TSH are in the normal range in all cases and T 3 is normal in 60%(3/5) and slightly increased in 40%(2/5). 4) In 10 patients who showed clinically borderline hypothyroidism after treatment of hyperthyroidism, TSH is increased in all cases and free T 4 and FTI are decreased in all cases, but T 4 and T 3 , T 4 /TBG ratio are in the normal limit in all cases. So after treatment of hyperthyroidism, TSH, free T 4 or FTI are recommended as optimal function test. 5) In normal pregnancy, free T 4 , FTI and T 4 /TBG ratio reflect normal function, but the other parameters unreliable due to the influence of increased TBG. Also TBG and TSH level in pregnancy is increased significantly compared with normal healthy control group. 6) The coefficients of correlation between T 4 and FTI were 0.862(p 4 and T 4 /TBG ratio. In most patients, diagnostic value of free T 4 was comparable and even superior to FTI, so free T 4 measurement can be used routinely with thyrotropin assay in the diagnosis of hypothyroidism or with T 3 for the diagnosis of hyperthyroidism.

    Bilharziasis in its different forms is estimated to affect at least 200 million people in the world (W.H.O., 1973). In egypt, it affects 60 - 70% of the rural population (WcMullen, 1963). Bilharzial ova reaches the liver with the portal blood stream causing a fibro - cellular reaction in and around the portal tract resulting in hepatic periportal fibrosis with various clinical stages (Abdalla et al., 1978 b). The effect of liver disease on thyroid function is still a subject of controversy and contradiction. While some reports are published on the effect of non-bilharzial liver disease on thyroid function, there is scanty studies as regards to bilharzial liver diseases . Most of the studies carried out to evaluate thyroid function in bilharzial liver disease, were focused on the estimation of one or two parameters of thyroid function e.g., T 3 and TSH. The available review of literature was focused on some parameters of thyroid function ignoring the others thyroid function tests and not considering the hormone carrier proteins. Thus resulting inconsistent and contradictory results (Ghareeb, 1962; El Haieg and Ibrahim, 1977)

    Full Text Available Background. Behcet’s disease (BD could be regarded as an autoimmune disease in many aspects. Autoimmune thyroid disease (ATD is frequently accompanied by other various autoimmune diseases. Nevertheless, there is not still enough data showing the association between BD and ATD. In addition, no controlled study is present in the PubMed, which evaluates thyroidal autoimmunity using antithyroid peroxidase antibody in a large series of patients with BD. Methods. We aimed to investigate the frequency of ATD in patients with BD. The study included 124 patients with BD and 99 age- and sex-matched healthy volunteers. Results. Autoimmune thyroiditis was noted in 21 cases (16.9% with BD. In the control group, 22 cases (22.22% were diagnosed as autoimmune thyroiditis. There was no difference between the groups in respect to thyroid autoantibodies (. There were no statistically significant differences between baseline TSH levels of the BD patients and of the controls (. Statistically, the mean serum free T4 levels of the patients with BD were higher than those of the controls (. Conclusions. No association could be found between BD and ATD. Therefore, it is not of significance to investigate thyroid autoimmunity in BD.

    1990-01-01

    Radioiodine treatment is considered to be the treatment of choice in benign thyroid diseases because of its very low side effects. Real and hypothetic risks and side effects have to be differentiated. Both may occur early and late after the treatment. Radioiodinethyroiditis in small volumes at high doses is very rare. Exacerbation of a thyroid storm (0.34%) as well as local compressions accompanied with reactive edema of the thyroid are early real side effects of radioiodine treatment. Late real side effects are failure of treatment (7-30% of thyrotoxicosis) and induction of hypothyroidism (4-20% of functional autonomy and increasing frequency in Graves' diseases with time). Late hypothetic risks are somatic (1-9/10000 bis 1-9/100000) or genetic (1-9/100000). An early risk might be the misdiagnosis of an additional thyroid carcinoma. (orig.) [de

    documented, but conflicting evidence suggests that thyrotropin levels in the upper part of the reference range may be associated with an increased risk of coronary heart disease (CHD). OBJECTIVE: To assess the association between differences in thyroid function within the reference range and CHD risk. DESIGN...... known thyroid or cardiovascular disease at baseline. EXPOSURES: Thyroid function as expressed by serum thyrotropin levels at baseline. MAIN OUTCOMES AND MEASURES: Hazard ratios (HRs) of CHD mortality and CHD events according to thyrotropin levels after adjustment for age, sex, and smoking status....... This finding suggests that differences in thyroid function within the population reference range do not influence the risk of CHD. Increased CHD risk does not appear to be a reason for lowering the upper thyrotropin reference limit....

    Autoimmune Thyroid Disease (AITD) is an autoimmune disease that has many clinical symptoms but is difficult to detect at the onset of disease progression. Most thyroid autoimmune disease patients are positive with high titre of thyroid autoantibodies, especially thyroid peroxidase (TPO). The detection AITD are still needed because these tests are extremely high cost and have not regularly been performed in most of clinical laboratories. In the past, we have explored the autoimmune disease marker and it has been developed as source of polyclonal antibodies from patient origin. In the current study, we develop recombinant protein which resulted from cloning and expression of TPO gene from normal person and AITD patients. This work flows involves: DNA isolation and PCR to obtain TPO gene from human blood, insertion of TPO gene to plasmid and transformation to E. coli BL21, Bacterial culture to obtain protein product, protein purification and product analysis. This products can use for application to immunochromatography based test. This work could achieved with the goal of producing autoimmune markers with a guaranteed quality, sensitive, specific and economically. So with the collaboration with industries these devices could be used for early detection.

    Ideas about the thyroid gland diseases development in people suffered from the Chernobyl accident explaining the absence of straight dose dependence of pathologies raise from the irradiation were elaborated. It is supposed that the probable reason for a number of these pathologies can be the unadecvate and inopportune preventive iodine administration. A simple immunological method of autoimmune thyroiditis diagnostics was developed which informativity is comparable with the method of ultra-sound diagnosis

    The etiopathogenesis of inflammatory bowel disease (IBD), encompassing Crohn's disease (CD) and ulcerative colitis (UC), is still not fully elucidated and seems to be multifactorial. It has been suggested that genetic, immunological and environmental factors participate in IBD development. IBD extraintestinal manifestations include rheumatic, metabolic, dermatologic, ophthalmologic, hepatobiliary, pancreatic, urologic, pulmonary, neurological, hematological and thromboembolic complications. Thyroid gland diseases have not been confirmed as extraintestinal manifestations of IBD. However, it is known that some thyroid diseases share an immunological background with IBD, and that dysfunction of the thyroid gland may induce gastrointestinal symptoms. Ultrasound examination is the gold standard for evaluation of thyroid gland morphology. This study was designed to assess the prevalence of abnormalities in the structure of the thyroid gland in IBD patients and to compare it to the control group. The study group consisted of 199 consecutive IBD patients (80 CD patients and 119 UC patients) hospitalized at the Department of Gastroenterology and Hepatology of Wroclaw Medical University (Poland). The control group consisted of 42 healthy volunteers and patients with functional gastrointestinal disorders. The most common finding in the ultrasound examination in IBD patients were tumors. Tumors, which were smaller than or equal to 10 mm were present in 11.5% of IBD patients; and tumors larger than 10 mm were present in 13.1%. These results show that small tumors (less than 10 mm in diameter) of the thyroid gland are more frequent among patients with CD and UC compared to the control group (p = 0.0001 and p = 0.001, respectively). Additionally, enlargement of the thyroid gland occurs more often in UC patients compared to the control group (p = 0.003). There was no difference in the frequency of thyroid abnormalities between UC and CD patients. In patients with inflammatory

    Full Text Available Autoimmune thyroid disease associated with interferon therapy can manifest as destructive thyroiditis, Graves’ Hyperthyroidism, and autoimmune (often subclinical hypothyroidism, the latter persisting in many patients. There are scare reports of a single patient developing extremes of autoimmune thyroid disease activated by the immunomodulatory effects of interferon. A 60-year-old man received 48 weeks of pegylated interferon and ribavirin therapy for chronic HCV. Six months into treatment, he reported fatigue, weight gain, and slowed cognition. Serum thyroid stimulating hormone (TSH was 58.8 mIU/L [0.27–4.2], fT4 11.1 pmol/L [12–25], and fT3 4.2 pmol/L [2.5–6.0] with elevated anti-TPO (983 IU/mL [<35] and anti-TG (733 U/mL [<80] antibodies. He commenced thyroxine with initial clinical and biochemical resolution but developed symptoms of hyperthyroidism with weight loss and tremor 14 months later. Serum TSH was <0.02 mIU/L, fT4 54.3 pmol/L, and fT3 20.2 pmol/L, with an elevated TSH receptor (TRAb, 4.0 U/L [<1.0], anti-TPO (1,163 IU/mL and anti-TG (114 U/mL antibodies. Technetium scan confirmed Graves’ Disease with bilateral diffuse increased tracer uptake (5.9% [0.5–3.5%]. The patient commenced carbimazole therapy for 6 months. Treatment was ceased following spontaneous clinical and biochemical remission (TSH 3.84 mIU/L, fT4 17pmol/L, fT3 4.5 pmol/L, and TRAb <1 U/L. This raises the need to monitor thyroid function closely in patients both during and following completion of interferon treatment.

Pre- and post-operative laboratory examination results and preoperative radiological and nuclear medicine findings of the patients were retrospectively recorded. A total number of 41 patients with PHPT were divided into two groups as the Group 1 with PHPT and benign thyroid pathology (21 patients) and the Group 2 with PHPT and malignant thyroid pathology (20 patients). In Group 1, 18 and 3 of 21 patients were females and males, respectively. Group 2 included 15 male and 5 female patients. The mean age of the patients was found to be 55.6 and 53.9 years in Group 1 and Group 2, respectively. Both groups were matched for age and gender. In terms of thyroid pathology, 20 of 41 patients (48.7%) who underwent total thyroidectomy for PHPT were found to have thyroid papillary carcinoma while benign pathologic conditions were detected in 21 (51.3%) individuals. Cooccurrence of thyroid diseases and PHPT is common. Therefore, all the patients should preoperatively be evaluated for the presence of thyroid pathology to determine the technique of parathyroid surgery.

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48{+-}13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease.

    Purpose: To evaluate the radiation exposure to the individuals other than patients with thyroid disease, who had received radioiodine (iodine-131) therapy and had turned into a specific 'radiant point'. Methods: 107 outpatients or inpatients, with iodine-131 therapy had been investigated and followed up by telephone and outpatients. There were 117 times treatment (68 females, 49 males, mean age 41 years old), including the patients with hyperthyroidism (39 females, 40 males), thyroid cancer (27 females, 8 males), toxic thyroid adenoma (1 female and 1 male) and nontoxic nodular goiter(1 female). According to the personal condition of the patients, we attained the percentage of thyroid iodine-131 uptake (U), the iodine-131 dose (Q), the duration of constrained social activity, and the occupancy factor (OF) for the 3 periods (the preequilibrium, OFp; the constrained, OFc; and the unconstrained, OFuc), and the time of exposure to individuals other than patients, and to calculate the exposure dose (mSv) to the individuals. The formula is E (mSv) = Q[OFP(0.0173)+ OFC(0.537)U(1-e-0.095C)+0.023(1-U)(1-e-2.08C ) +OFUC (0.537) Ue-0.095C +0.0236(1-U)e-2.08C]. In accordance with the new recommendations of the national criteria from GB18871-2002, we evaluated the radiation safety to the individuals other than patients Results: Based on the national criteria the total effective dose equivalent to the individuals other than patients may not exceed 5 mSv. For all patients, including 79 hyperthyroidism, 2 toxic thyroid adenoma and 16 times treatment of thyroid cancer, the exposure doses to the individuals were not likely to exceed 5 mSv, but the others, including 19 times treatment of thyroid cancer and 1 nontoxic nodular goiter, the exposure doses were higher than 5 mSv. There were no difference between the part of hyperthyroidism and thyroid cancer of inpatients were compared with outpatients (P>0.05, respectively). we found that occupancy factor during the preequilibrium period

    Autoimmune diseases occur due to faulty self-tolerance. Graves' disease (GD) and Hashimoto's thyroiditis (HT) are classic examples of organ-specific autoimmune diseases. GD is an auto-antibody-mediated disease where autoantibodies are produced against the thyroid stimulating hormone receptor (TSHR...... (Bregs) and regulatory T cells (Tregs) were investigated in the context of GD and HT. First, we studied the role of the thyroid self-antigen, thyroglobulin (TG) in healthy donors. The self-antigen TG, but not the foreign recall antigen tetanus toxoid (TT), was able to induce interleukin 10 (IL-10......) secretion by B cells and CD4+ T cells. These IL-10 producing B cells (B10 cells) from healthy donors were enriched with the CD5+ and CD24hi phenotype. In addition, TG was able to induce IL-6 production by B cells. In contrast, TT induced production of Th1-type pro-inflammatory cytokines including interferon...

    To evaluate remission rate of anti-thyroid drug treatment in patients with Grave's disease, and to study the factors associated with remission. A cross sectional study. The Endocrine Department of the Aga Khan University Hospital, Karachi from 1999 to 2000. Seventy four patients of Grave's disease were recruited who were prescribed medical treatment. Grave's disease was diagnosed in the presence of clinical and biochemical hyperthyroidism along with anti-microsomal (AMA) and anti-thyroglobulin antibodies (ATA) and thyroid scan. These patients were prescribed oral anti-thyroid drugs using titration regime and followed at 3, 6, 12 and 18 months. Patients were categorized into two groups: "remission group" and "treatment failure group" and results were compared using a chi-square test, t-test and logistic regression model with significance at p disease on initial presentation.

    Full Text Available We investigated the association between autoimmune thyroid disease and systemic lupus erythematosus (SLE using nationwide insurance claims data for the entire Korean population. Claims data for the period 2009-2013 were retrieved from the National Health Insurance System database. SLE and thyroid disease were identified using the International Classification of Diseases codes and medication information. Logistic regression analyses were used to evaluate the association between SLE and thyroid disease. The study used records from 17,495 patients with SLE and 52,485 age- and sex-matched control subjects. A greater prevalence of Graves' disease (0.94% vs. 0.46%, P < 0.001, Hashimoto's thyroiditis (2.68% vs. 0.80%, P < 0.001, and thyroid cancer (1.81% vs. 1.30%, P < 0.001 was observed in SLE patients than in control subjects. Multivariate regression analyses demonstrated that SLE was significantly associated with an increased risk of both autoimmune thyroid disease and thyroid cancer (Graves' disease: odds ratio [OR] 2.07, 95% confidence interval [CI] 1.70-2.53; Hashimoto's thyroiditis: OR 3.42, 95% CI 3.00-3.91; thyroid cancer: OR 1.40, 95% CI 1.22-1.60. Age- and sex- stratified analyses revealed that the risk of autoimmune thyroid disease in SLE patients was increased for all age groups and the female group. An association between thyroid cancer and SLE was identified only in the 20- to 59-year-old age group and in the female group. Using a large population-based study, we demonstrated that patients with SLE are at a greater risk of developing thyroid disease than matched control individuals.

    To identify the late effects of radio- chemotherapy (CTH) on thyroid gland in long-term survivors (LTS) HD patients regularly attending the pediatric oncology clinic of National Cancer Institute (NCI), 42 LTS (33 males and 9 females) were studied, together with 26 newly-diagnosed (ND) HD patients (15 males and 11 females) and 28 healthy controls. During 3 years period, all patients subjected to through clinical history/ examination. Files of LTS were revised for date of diagnoses, original site (s), stage, histopathological subtypes and dose/ duration of therapy. Clinical examination was done with laying stress on neck examination for thyroid swelling and lymphadenopathy. Lab investigations include hormonal assay of thyroid and parathyroid (T3, T4, TSH, Thyroglobin, and parathormone). In LTS the mean age was 14.9±3.4 yrs. versus 9.5±3.7 yrs. in ND patients. In LTS, treatment modalities included radiotherapy (RT) alone (2.4%), CTH alone (26.2%) or combination chemo-RT (71.4%). The mean followup time was 7.47±2.19 yrs. The incidence of hyper-/hypo-thyroidism was significantly higher in LTS. High TSH was found only among patients who received chemo-RT (11/26) with thyroid irradiation (IR) in the whole neck field. Finally, the study documented that the hyper-/hypo-thyroidism was one of the long-term complication of radio-CTH in HD patients. Recommendations regarding the follow-up of therapy for HD were discussed. New strategies and evidence based surveillance of the long-term effects are needed for dealing with HD, especially in children

    Hydatid cyst disease may develop in any organ of the body, most frequently in the liver and lung, but occasionally can affect other organs such as the thyroid gland. Although the prevalence of thyroidal cyst disease varies by region, literature data suggest that it ranges between 0% and 3.4%. The aim of this report was to share 2 cases with thyroid hydatid cyst. Two female patients aged 26 and 57 years were admitted to our outpatient clinic with different complaints. While the first case presented with front of the neck swelling and pain, the second case presented with hoarseness, sore throat, and neck swelling. Both patients were living in a rural area in the southeastern region of Turkey and had had a long history of animal contact. Both patients had undergone previous surgeries for hydatid cyst disease. Both patients presented with a clinical picture consistent with typical multinodular goiter, and both underwent total thyroidectomy after detailed examinations and tests. The exact diagnosis was made after histopathologic examination in both patients. They both had a negative indirect hemagglutination test studied from blood samples. They both have had no recurrences during a 4-year follow-up. In conclusion, although thyroid gland is rarely affected, hydatid cyst disease should not be overlooked in differential diagnosis of cystic lesions of thyroid gland in patients who live in regions where hydatid cyst disease is endemic and who had hydatid cysts in other regions of their body.

    The aim of this study was to estimate sodium iodide symporter (NIS) and thyroid peroxidase (TPO) expression in thyrocytes from patients with GD and no-toxic multi nodular goitre (NTMG) in relationship with apoptotic (TIAR and TIA-1) markers. The investigation was performed on thyroid cells isolated from post operation thyroid tissues from 15 patients aged 12-21 years old with GD and 15 cases aged 13-21 years old with NTMG. Detection of NIS and TPO was performed by immunohistochemistry. Analysis of apoptotic markers in thyroid tissues was performed using antibodies to TIAR and TIA-1 by Western Blot and immunohistochemistry. Identification of pro apoptotic TIAR and TIA-1 molecules in the thyroid tissues revealed a higher expression of both proteins in patients with Graves' disease (+++; +, respectively) in comparison to patients with NTNG (+; 0). In addition, TIAR expression was detected in three bands [p50, p42, p38 (kDa)] and TIA-1 in two bands [p22, p17 (kDa)]. using Western Blot test in patients with thyroid autoimmune diseases. In patients with NTNG expression of both apoptotic proteins was lower and identified in single bands: 42 (kDa) for TIAR and 17 (kDa) for TIA-1. The analysis of expression of NIS and TPO in thyroid follicular cells was higher in patients with Graves' disease in compared to their detection in patients with NTMG. In addition, degree of thyroid antigen expression positive correlated with amount of pro apoptotic markers (TIAR, p<0.001; TIA-1, p<0.025 for NIS; TIAR, p<0.012 for TPO). We conclude that elevated expression of NIS and TPO in Graves' disease is associated with higher stimulation and activation of apoptosis in thyroid follicular cells during autoimmune process.

    The activity to be administered in I-131 therapy of benign thyroid disease is determined by the radiation absorbed dose necessary to cure the disease, the target mass, and the residence time of the I-131 in the target volume. Data from 73 patients with complete sets of uptake measurements 2, 6, 24, 48, and 96 (n = 53) or 120 (n = 20) hours after oral administration of 1 MBq I-131 were used to deduce residence times from subsets of 3, 2, or only 1 measurement for each individual. The values were compared to those obtained with the reference method, i.e. a fit of an uptake function based on a 2-compartment model to all 5 measurements, to quantify the errors introduced by the less demanding assessments. Deviations are less than 10% if the 2- compartment uptake function is fitted to only 3 values measured after 6, 24, and 96-120 h. Use of 2, 24, and 96-120 h data results in errors > 20% in individual patients. The effective half-lives as determined from 2 measurements after 24 and 96-120 h correlate well with those deduced from the reference method with larger deviations in individuals with slow iodine kinetics and late maximal uptake. Residence times determined from the 24 h uptake, assuming linear increase during the first day, and the effective half-life limited to maximum 8 days underestimate the actual values systematically in patients with long and short half-lives. These errors can be eliminated by a modification of the calculation method resulting in deviations less than 14% in all but one individual for this procedure. The accuracy of methods based on only one retention value increases with the time of measurement after the administration of I-131. While systematic errors up to a factor of two occur if the 24 h uptake is used for the estimate, deviations are less than 18% for measurements after 120 h. The results suggest that only one late uptake assessment warrants residence time estimates with an acceptable error. Given the high inherent uncertainties in the

    Full Text Available The problem of a pathology of a thyroid gland at rheumatic diseases, in particular at rheumatoid arthritis, remains actual and to this day. The work purpose was studying antitelogenesis to thyroid hormones at patients with mixt autoimmune pathology. In whey of blood of patients with RA and autothyroid pathology are found out antibodies (AB to Т3 and Т4, their concentration correlates with activity of pathological process. It is shown, that level AB to Т3 and Т4 authentically differs from the maintenance of the given antibodies in whey of blood of healthy faces. Level of antibodies to thyroid hormones can be considered as the criterion predicting development of pathology of a thyroid gland at patients with RA.

    It was determined by experts that in the region adjacent to the Semipalatinsk Nuclear Test Site thyroid nodular prevalence was significantly associated with radiation dose from nuclear weapons testing. The medical rehabilitation of patients is of special practical and scientific importance in this region. Some patients have contraindications for surgery and radioiodine or refuse them for various reasons. Percutaneous intranodular injection therapy by "Paoscle" (PIITP) was used for treatment of patients with benign thyroid nodular diseases. The study group included a total of 107 patients (mainly "pretoxic" and "compensated" nodules). Seventy-four patients received PIITP on an out-patient basis. Seventy-two of them were women and 2 men, mean age, 52.9 +/- 1.3 years; range 26 to 77 years. Thyroid ultrasound examination, fine-needle aspiration biopsy, thyroid function tests and cytopathology were performed in all patients to evaluate the effectiveness of treatment. The nodule volume reduction rate for patients with thyroid adenomas was 56 % on average and 60.2 % in the case of colloid nodules. The reduction rate of thyroid adenomas with necrotic and cystic degeneration was higher and reached 72 %. The suggested method is indicated for cases of benign nodular thyroid diseases (cysts, adenomas, adenomas with necrotic and cystic degeneration, colloid nodules, polynodular goiter). We did not reveal any complications or thyroid test abnormalities after the treatment. A tendency to normalization of the blood serum thyroglobulin level and antibodies to thyroglobulin was documented. Analysis of the treatment results revealed that this approach is effective, inexpensive, safe, well tolerated and can be used on an outpatient basis.

    Chronic thyroiditis (Hashimoto's disease) is a slowly developing persistent inflamation of the thyroid gland, which frequently leads to hypothyroidism. Some of the up-to-date knowledge about hypothyroidism, both subclinical and manifested, caused by autoimmune disease, was presented. Autoimmune thyroid gland disease can occur at any age, but predominantly affects women after periods of high emotional and physical stress or accidents, as well as during periods of hormonal changes. It can also develop in families, and having an autoimmune disease slightly increases the risk of developing another. This paper showed an increasing incidence of subclinical hypothyroidism (4.17%) in elderly, and, at the same time, the incidence of primary hypothyroidism accounting for 1%. It is very usefull to estimate the stimulated thyrotropin (TSH) response, as well as the value of fast, short time thyroid gland reserves, analyzed by T3 and T4 serum level at 60th minute after TRH stimulation. Treatment of choice for HT (hypothyroidism of any cause) is thyroid hormone replacement. Drug of choice is orally administered levothyroxine sodium, usually for life-time. The standard dose is 1.6-1.8 mcg/kg body weight per day, but is in most cases patient dependent. Elderly patients usually require smaller replacement dose of levothyroxine, sometimes less than 1 mcg/kg body weight per day with coronary dilatator at the same time.

    Thyroid cancer and Graves' disease may present simultaneously in one patient. The incidence of the development of hyperthyroidism from metastatic differentiated thyroid carcinoma is rare. We herein report a case of metastatic follicular carcinoma complicated with Graves' disease after total thyroidectomy. A 57-year-old woman underwent right hemithyroidectomy for follicular carcinoma. Metastatic lesions appeared in the lungs and skull two years after the first surgery, and remnant thyroidectomy was performed for radioactive iodine-131 (RAI) therapy, during which the TSH receptor antibody (TRAb) was found to be negative. The patient was treated with RAI therapy four times for four years and was receiving levothyroxine suppressive therapy. Although radioiodine uptake was observed in the lesions after the fourth course of RAI therapy, metastatic lesions had progressed. Four years after the second surgery, she had heart palpitations and tremors. Laboratory data revealed hyperthyroidism and positive TRAb. She was diagnosed with Graves' disease and received a fifth course of RAI therapy. 131I scintigraphy after RAI therapy showed strong radioiodine uptake in the metastatic lesions. As a result, the sizes and numbers of metastatic lesions decreased, and thyroid function improved. Metastatic lesions produced thyroid hormone and caused hyperthyroidism. RAI therapy was effective for Graves' disease and thyroid carcinoma.

    Full Text Available Objective. This study aimed to evaluate the CT features of incidentally detected DTD in the patients who underwent thyroidectomy and to assess the diagnostic accuracy of CT diagnosis. Methods. We enrolled 209 consecutive patients who received preoperative neck CT and subsequent thyroid surgery. Neck CT in each case was retrospectively investigated by a single radiologist. We evaluated the diagnostic accuracy of individual CT features and the cut-off CT criteria for detecting DTD by comparing the CT features with histopathological results. Results. Histopathological examination of the 209 cases revealed normal thyroid (n=157, Hashimoto thyroiditis (n=17, non-Hashimoto lymphocytic thyroiditis (n=34, and diffuse hyperplasia (n=1. The CT features suggestive of DTD included low attenuation, inhomogeneous attenuation, increased glandular size, lobulated margin, and inhomogeneous enhancement. ROC curve analysis revealed that CT diagnosis of DTD based on the CT classification of “3 or more” abnormal CT features was superior. When the “3 or more” CT classification was selected, the sensitivity, specificity, positive and negative predictive values, and accuracy of CT diagnosis for DTD were 55.8%, 95.5%, 80.6%, 86.7%, and 85.6%, respectively. Conclusion. Neck CT may be helpful for the detection of incidental DTD.

    Full Text Available BackgroundThe purpose of this study is to analyze the scale of and trends associated with the cost-of-illness of thyroid disease in Korea at 2-year intervals during the last 10 years for which data are available.MethodsCost-of-illness was estimated in terms of direct and indirect costs. Direct costs include direct medical costs due to hospitalization, outpatient and pharmacy sectors, transportation, and care-giver costs. Indirect costs include future income loss due to premature death and loss of productivity as a result of absence from work.ResultsThe cost-of-illness of thyroid disease in Korea was estimated at 224.2 billion won in 2002, 303.4 billion won in 2004, 400.3 billion won in 2006, 570.4 billion won in 2008, and 762.2 billion won in 2010. For example, the cost-of-illness of thyroid disease in 2010 was 3.4 times greater compared to 2002. The direct cost of the total cost-of-illness was 69.7%, which accounted for the highest proportion of costs. Cost-of-illness for individuals between the ages of 30 and 50 accounted for the greatest share of costs.ConclusionThe cost-of-illness of thyroid disease was relatively large in economically active age groups, and demonstrated a very rapid growth rate compared to other major diseases in Korea. Therefore, we suggest nationwide recognition of the importance of prevention and management of thyroid disease and prioritization of the management of thyroid disease among current and future health promotion policies in Korea.

    We studied the effects of radioiodine therapy (RIT) for autonomously functioning thyroid nodules (AFTNs) and Graves' disease on thyroid function and size up to one year after RIT. In 230 patients with AFTNs, a dose of 300 Gy was effective in about 90% of the cases 6 months after RIT. Out of 65 patients suffering from Graves' disease, 5 patients (8%) had persisting hyperthyroidism 6 months after RIT with a dose of 150 Gy. This group consisted exclusively of patients with manifest hyperthyroidism at the time of RIT. As determined by ultrasonography 6 months after RIT, a reduction of thyroid size by about 40% and 60% was observed in patients with AFTNs and Graves' disease, respectively. (orig.) [de

Methods: The following groups were included: 250 healthy subjects without goiter, 50 persons with diffuse goiter, 161 patients with multinodular goiter devoid of functional disorder (108 of them underwent surgery, in 17 cases carcinomas were detected), 60 hyperthyroid patients with autonomously functioning nodular goiter, 150 patients with Hashimoto's thyroiditis and 30 hyperthyroid patients with Graves' disease. Results: The upper limit of the normal range of the Tg level was calculated as 30 ng Tg/ml. The evaluation of the collective with diffuse goiter showed that the figure of the Tg level can be expected in a similar magnitude as the thyroid volume in milliliters. Nodular tissue led to far higher Tg values then presumed when considering the respective thyroid volume, with a rather high variance. A formula for a rough prediction of the Tg levels in nodular goiters is described. In ten out of 17 cases with thyroid carcinoma, the Tg was lower than estimated with thyroid and nodular volumes, but two patients showed a Tg exceeding 1000 ng/ml. The collective with functional autonomy had a significantly higher average Tg level than a matched euthyroid group being under suppressive levothyroxine substitution. However, due to the high variance of the Tg values, the autonomy could not consistently be predicted with the Tg level in individual cases. The patients with Hashimoto's thyroiditis showed slightly decreased Tg levels. In Graves' disease, a significantly higher average Tg level was observed compared with a matched group with diffuse goiter, but 47% of all Tg values were still in the normal range ( [de

    Considerable epidemiological evidence exists to link thyroid disease with differing patterns of dietary consumption, in particular, cruciferous vegetables. We have been studying the anti-thyroid cancer (TCa) activity of indole-3-carbinol (I3C) found in cruciferous vegetables and its acid catalyzed dimer, 3,3'-diindolylmethane (DIM). There are no studies as yet to elucidate the effect of these compounds on the altered proliferative patterns in goiter or thyroid neoplasia. In this study, we tested the anti-proliferative effects of I3C and DIM on four different thyroid cancer cell lines representative of papillary (B-CPAP and 8505-C) and follicular carcinoma of the thyroid (CGTH-W-1 and ML-1), and primary human goiter cells. Cell survival and IC 50 values for I3C and DIM were calculated by the XTT assay and cell cycle distribution analysis was done by flow cytometry. DIM was found to be a better anti-proliferative agent than I3C in both papillary and follicular TCa resulting in a greater cytotoxic effect at a concentration over three fold lower than predicted by the molar ratio of DIM and I3C. The anti-proliferative activity of DIM in follicular TCa was mediated by a G1 arrest followed by induction of apoptosis. DIM also inhibited the growth of primary goiter cells by 70% compared to untreated controls. Contrary to traditional belief that cruciferous vegetables are 'goitrogenic,' DIM has anti-proliferative effects in glandular thyroid proliferative disease. Our preclinical studies provide a strong rationale for the clinical exploration of DIM as an adjuvant to surgery in thyroid proliferative disease

    Hypothyroidism and hyperthyroidism are commonly present conditions in adults, leading to neurological symptoms, affecting the central and peripheral nervous system, and to neurocognitive impairment. Several studies investigated a possible association between Alzheimer's disease (AD) and thyroid dysfunctions. Increasing evidence supports an extensive interrelationship between thyroid hormones and the cholinergic system, which is selectively and early affected in AD. Moreover, thyroid hormones negatively regulate expression of the amyloid-beta protein precursor (AbetaPP), which plays a key role in the development of AD. A condition, the so called euthyroid sick syndrome (ESS), characterized by reduced serum T_{3} and T_{4} concentrations without increased serum thyroid stimulation hormone secretion, occurs within hours after major surgery. After surgery, elderly patients often exhibit a transient, reversible state of cognitive alterations. Delirium occurs in 10-26% of general medical patients over 65, and it is associated with a significant increase in morbidity and mortality. Modifications in thyroid hormone functioning may take place as a consequence of psycho-physical stress caused by surgery, and probably as a consequence of reduced conversion of T4 into T3 by the liver engaged in metabolizing anesthetic drugs. Therefore, modifications of thyroid hormones post-surgery, might play a role in the pathogenesis of postoperative cognitive dysfunction.

    For a better understanding of the pathogenesis of thyroid autoimmune diseases, we have studied morphological and functional properties of T clones from peripheral blood lymphocytes (PBL) and from intrathyroidal lymphocytes (ITL) obtained from 3 patients with Graves' disease or 1 Hashimoto's thyroiditis. Investigations were carried out on clones cultured alone or cocultured with autologous thyrocytes. Clonage efficiency ranged from 30% to 33% for PBL and 10% to 36% for ITL. A predominance of CD4-positive clones was observed whatever the origin of the lymphocytes or the autoimmune pathology. Gamma interferon (IFN-gamma) was detected in the majority (17/19) of the clones tested. Intracytoplasmic interleukin (IL-4) was secreted in 7/19 clones and both cytokines were produced in 5/19 clones. In coculture a proliferative response and tumour necrosis factor (TNF-alpha) production were observed with 6 clones (4 from Graves thyrocytes and 2 from thyroiditis). No cytotoxic clone was derived from Graves or thyroiditis tissues. These data demonstrate that the large majority of T clones are principally CD4-T cells; all the clones secreted TNF-alpha and a large majority produced IFN-gamma. Only a few clones produced IL-4 alone or associated with IFN-gamma. Six T clones induced proliferative response and of TNF-alpha secretion in coculture. Further investigations must be performed on these antigen-reactive T clones to analyse their role in the pathogenesis of the human thyroid autoimmune diseases.

    Serum TSH was measured by means of double antibody radioimmunoassay using a commercial Kit Daiichi, in 21 normal subjects, 200 patients with thyroid disease and 130 patients with hypothalamic-pituitary diseases. Serum TSH concentrations in normal subjects were <2 to 8 μU/ml which rose to 8-40 μU/ml after administration of 500 μg TRH intravenously. Serum TSH was undetectable and did not respond to TRH in all untreated patients and in some euthyroid patients with Graves' disease after treatment. Undetectable TSH and no response to TRH were also observed in most patients with a hyperfunctioning thyroid nodule and those with subacute thyroiditis in the acute phase. In some patients with Hashimoto's thyroiditis and all patients with adult myxedema and cretinism, serum TSH levels were increased and showed hyperresponse to TRH. The ratio of bioassay and radioimmunoassay potency estimates for TSH in sera obtained before TRH was not statistically different from that obtained after TRH administration to patients with primary hypothyroidism. Elevated serum TSH was promptly decreased by the administration of thyroid hormone to the patients. More than 50% of patients with pituitary adenoma, acromegaly and craniopharyngioma showed normal basal TSH and no or low response of TSH to TRH. Administration of TRH failed to stimulate a rise in serum TSH in 2 sisters with isolated TSH deficiency with cretinism. Basal TSH was undetectable and showed delayed response to TRH in patients with anorexia nervosa. (auth.)

    We saw 24 thyrotoxic Graves' patients with normal thyroidal uptake of technetium-99m pertechnetate ({sup 99m}Tc) out of 201 untreated thyrotoxic Graves' patients seen over 4 years. The clinical and laboratory findings for these patients were studied and analyzed. Thyroid uptake and scintigraphic examinations by means of {sup 99m}Tc, TBII and TSab activity measurement clearly distinguished these patients from other thyrotoxic disorders (destruction-induced thyrotoxicosis and autonomously functioning thyroid lesions). Different from other disorders, these patients had not lower but normal thyroid uptake and also showed diffuse and discrete trapping into the enlarged glands. These patients had significantly smaller goiters, a lower serum thyroid hormone level, and lower TBII and TSab activity, when compared with other high {sup 99m}Tc uptake groups with Graves' disease, and their condition could be easily controlled with small amounts of antithyroid drugs. Our study indicates that thyrotoxic Graves' disease with normal {sup 99m}Tc uptake exists and {sup 99m}Tc uptake study and TBII activity measurement is very useful for the diagnosis. The normal {sup 99m}Tc uptake thyrotoxic Graves' patient might be early stage patients with general Graves' disease and their early discrimination from general Graves' patients is very advantageous for treatment and prognosis.

    Background Autoimmune thyroid disease (AITD) comprises diseases including Hashimoto's thyroiditis and Graves' disease, both characterized by reactivity to autoantigens causing, respectively, inflammatory destruction and autoimmune stimulation of the thyroid-stimulating hormone receptor. AITD is the most common thyroid disease and the leading form of autoimmune disease in women. Cytokines are key regulators of the immune and inflammatory responses; therefore, genetic variants at cytokine-encoding genes are potential risk factors for AITD. Methods Polymorphisms in the IL6-174 G/C (rs1800795), TNFA-308 G/A (rs1800629), IL1B-511 C/T (rs16944), and IFNGR1-56 T/C (rs2234711) genes were assessed in a case-control study comprising 420 Hashimoto's thyroiditis patients, 111 Graves' disease patients and 735 unrelated controls from Portugal. Genetic variants were discriminated by real-time PCR using TaqMan SNP genotyping assays. Results A significant association was found between the allele A in TNFA-308 G/A and Hashimoto's thyroiditis, both in the dominant (OR = 1.82, CI = 1.37–2.43, p-value = 4.4×10−5) and log-additive (OR = 1.64, CI = 1.28–2.10, p-value = 8.2×10−5) models. The allele C in IL6-174 G/C is also associated with Hashimoto's thyroiditis, however, only retained significance after multiple testing correction in the log-additive model (OR = 1.28, CI = 1.06–1.54, p-value = 8.9×10−3). The group with Graves' disease also registered a higher frequency of the allele A in TNFA-308 G/A compared with controls both in the dominant (OR = 1.85, CI = 1.19–2.87, p-value = 7.0×10−3) and log-additive (OR = 1.69, CI = 1.17–2.44, p-value = 6.6×10−3) models. The risk for Hashimoto's thyroiditis and Graves' disease increases with the number of risk alleles (OR for two risk alleles is, respectively, 2.27 and 2.59). Conclusions This study reports significant associations of genetic variants in TNFA and

    To study the clinical value of serum TGAb and TPOAb levels in the diagnosis of patients with autoimmune thyroid diseases (AITD), the serum levels of TGAb and TPOAb in 175 patients with AITD and 64 non-AITD patients and 57 health controls were measured by RIA. The results showed that the serum levels of TGAb and TPOAb in AITD patients with GD and HT were significantly higher than that of control group (P 0.05). The detection of serum TGAb and TPOAb levels may have clinical value in the diagnosis, treatment and prognosis of autoimmune thyroid diseases. (authors)

  4. Selenium, selenoproteins and the thyroid gland: interactions in health and disease.

    The trace element selenium is an essential micronutrient that is required for the biosynthesis of selenocysteine-containing selenoproteins. Most of the known selenoproteins are expressed in the thyroid gland, including some with still unknown functions. Among the well-characterized selenoproteins are the iodothyronine deiodinases, glutathione peroxidases and thioredoxin reductases, enzymes involved in thyroid hormone metabolism, regulation of redox state and protection from oxidative damage. Selenium content in selenium-sensitive tissues such as the liver, kidney or muscle and expression of nonessential selenoproteins, such as the glutathione peroxidases GPx1 and GPx3, is controlled by nutritional supply. The thyroid gland is, however, largely independent from dietary selenium intake and thyroid selenoproteins are preferentially expressed. As a consequence, no explicit effects on thyroid hormone profiles are observed in healthy individuals undergoing selenium supplementation. However, low selenium status correlates with risk of goiter and multiple nodules in European women. Some clinical studies have demonstrated that selenium-deficient patients with autoimmune thyroid disease benefit from selenium supplementation, although the data are conflicting and many parameters must still be defined. The baseline selenium status of an individual could constitute the most important parameter modifying the outcome of selenium supplementation, which might primarily disrupt self-amplifying cycles of the endocrine-immune system interface rectifying the interaction of lymphocytes with thyroid autoantigens. Selenium deficiency is likely to constitute a risk factor for a feedforward derangement of the immune system-thyroid interaction, while selenium supplementation appears to dampen the self-amplifying nature of this derailed interaction.

    Objective: To explore the clinical value of TRAb RRA for the diagnosis and treatment-guide of thyroid diseases. Methods: Serum TRAb levels were determined with RRA in 295 patients with various kinds of thyroid diseases (Graves' disease, uncontrolled 155; Graves' disease, controlled 80; Primary hypothyroidism, 25; autonomous hyperfunctioning adenoma, 15; simple goiter 20) and 45 controls. Results: Serum TRAb levels in the patients with Graves' disease, controlled and uncontrolled, and patients with primary hypothyroidism were significantly higher than those in the controls (P 0.05). Also, there was not much difference between levels of TRAb in patients with uncontrolled and controlled Graves' disease (P>0.05). Conclusion: TRAb is possibly involved in the pathogenesis of Graves' disease and primary hypothyroidism and may serve as an useful diagnostic parameter. However, TRAb levels are not related to the severity of hyperthyroidism. (authors)

    Objective: To detect the level of serum interleukin-6 (IL-6) and insulin-lide growth factor-1 (IGF-1) in patients with thyroid eye disease and to seek the relationship between serum level and the outbreak as well as the condition variety. Methods: To measure the level of serum IL-6 and IGF-1 by radioimmunoassay in 30 patients with thyroid eye disease after their clinical expression and activity score have been assessed, 30 patients with hyperthyroidism but without ophthalmopathy, 30 healthy subjects. Results: The level of serum IL-6 and IGF-1 in patients with thyroid eye disease were higher than that of patients with hyperthyroidism but without ophthalmopathy (t=4.20, t=4.00, P<0.01) and healthy subjects (t=4.20, t=4.05, P<0.01). IL-6 and IGF-1 levels tend to elevate with the increase of severity of eye disease. There were significant differences among them. Conclusion: The leve of IL-6, IGF-1 and the cause of thyroid eye disease are closely related, and IL-6 and IGF-1 levels in peripheral blood might reflect the severity of eye disease. (authors)

Methods: 15 patients undergone core needle biopsy of the thyroid gland were divided into three groups according to the amount of time elapsed after thyroid arterial embolization: A group, before thyroid arterial embolization, B group, 1 year group (including 7-day subgroup, 3-month subgroup, 6-month subgroup) and C group, 1 year subgroup and mom than 1 year subgroup after arterial embolization. Results: (1) After embolisation, 15 patients' symptoms and signs of hyperthyroidism disappeared or improved greatly with 9 long term released and 6 improved with small amount of ATD maintenance. (2) The positive staining of Fas and FasL located in endochylema and cell-membrane of thyroid tissue from patients treated with transcathter arterial embolization were higher than those not treated with transcathter arterial embolization (P 0.05). (4) The positive cell and the staining of P53 in thyroid tissue had significant difference before and after thyroid arterial embolization (P<0.05). Conclusions: The extra-expression and the increased expression of Fas, FasL, Bax, P53 in thyroid tissue of patient with GD treated by thyroid arterial embolization are correlated with the effects of interventional therapy.

    To assess the role of diffusion-weighted MR imaging in differentiation between Graves' disease and painless thyroiditis. A prospective study was conducted among 37 consecutive patients with untreated thyrotoxicosis (25 female and 12 male; mean age of 44 years) and 15 ageand sex-matched controls. Diffusion-weighted MR imaging of the thyroid gland was performed in patients and controls. The apparent diffusion coefficient (ADC) value of the thyroid gland was calculated and correlated with Tc-99m uptake and thyroid function tests of the patients. There was a significant difference in the ADC value of the thyroid gland between patients and the control group ( P =0.001). The mean ADC value of the thyroid gland in Graves' disease was 2.03±0.28×10 -3 mm 2 /sec, and in patients with painless thyroiditis 1.46±0.22×10 -3 mm 2 /sec, respectively. There was a significant difference in the ADC values between Graves' disease and painless thyroiditis ( P =0.001). When the ADC value of 1.45×10 -3 mm 2 /sec was used as a threshold value for differentiating Graves' disease from painless thyroiditis, the best result was obtained with area under the curve of 0.934, accuracy of 83.8%, sensitivity of 95.8%, and specificity of 61.5%. The mean ADC value of the thyroid gland in patients positively correlated with serum TRAb and Tc-99m uptake ( r =0.57, P =0.001 and r =0.74, P =0.001, respectively). We concluded that ADC values of the thyroid gland can be used to differentiate Graves' disease from painless thyroiditis in patients with untreated thyrotoxicosis.

    Full Text Available Background: The objective of this study was to determine the prevalence of the metabolic syndrome and its components in people with thyroid disorders. Materials and Methods: 112 subjects with a history of thyroid disorders were consecutively enrolled for the study. Clinical data were obtained by interviewing the patients and referring to their case folders and prescriptions. The subjects were categorized into three: thyrotoxic, those with hypothyroidism and those with nontoxic goiters, based on clinical parameters and or thyroid function tests. The study subjects were weighed and their anthropometric indices were documented. The laboratory parameters that were analyzed included total cholesterol, high-density and low-density cholesterol and triglyceride. Statistical analysis was performed using Student′s t test, one-way analysis of variance (ANOVA test and chi-square test. Results: The study subjects were aged between 14 and 76 years, with a mean age of 44.5 years, and the female:male ratio was 97:15. The mean age and anthropometric indices were comparable in subjects with thyrotoxicosis, hypothyroidism and euthyroidism. The overall prevalence of the metabolic syndrome was 28% and the frequency of occurrence of the metabolic syndrome in subjects with thyrotoxicosis, hypothyroidism and nontoxic goiter was 24%, 40% and 42%, respectively. The commonest occurring metabolic syndrome defining criterion was dysglycemia, while hypertension and elevated triglyceride were the least documented of the criteria. Conclusion: Metabolic syndrome occurs in 1 in every 4 persons with thyroid disorders, and as such, routine screening for this cardiovascular risk factor may be of benefit in this group of people, especially in those with hypothyroidism.

    The term thyroiditis comprises a group of thyroid diseases characterized by the presence of inflammation, including autoimmune and non-autoimmune entities. It may manifest as an acute illness with severe thyroid pain (subacute thyroiditis and infectious thyroiditis), and conditions in which the inflammation is not clinically evident evolving without pain and presenting primarily thyroid dysfunction and/or goiter (drug-induced thyroiditis and Riedel thyroiditis). The aim of this review is to provide an updated approach on non-autoimmune thyroiditis and its clinical, diagnostic and therapeutic aspects.

    Objectives 1) Describe thyroid-related diagnoses and procedures in CHEER across academic and community sites. 2) Compare management of malignant thyroid disease across these sites, and 3) Provide practice based data related to flexible laryngoscopy vocal fold assessment before and after thyroid surgery based on AAO-HNSF Clinical Practice Guidelines. Study Design Review of retrospective data collection (RDC) database of the CHEER network using ICD-9 and CPT codes related to thyroid conditions. Setting Multisite practice based network. Subjects and Methods There were 3,807 thyroid patients (1,392 malignant; 2,415 benign) with 10,160 unique visits identified from 1 year of patient data in the RDC. Analysis was performed for identified cohort of patients using demographics, site characteristics and diagnostic and procedural distribution. Results Mean number of patients with thyroid disease per site was 238 (range 23–715). In community practices, 19% of patients with thyroid disease had cancer versus 45% in the academic setting (pVocal fold function was assessed by flexible laryngoscopy in 34.0% of pre-operative patients and in 3.7% post-operatively. Conclusion This is the first overview of malignant and benign thyroid disease through CHEER. It shows how the RDC can be used alone and with national guidelines to inform of clinical practice patterns in academic and community sites. This demonstrates the potential for future thyroid related studies utilizing the Otolaryngology-H&N Surgery’s practice-based research network. PMID:27371622

    Many reports have supported the relationship between high preoperative TSH levels and risk of thyroid cancer in nodular thyroid disease (NTD). We investigated whether TSH levels are related to the risk of differentiated thyroid carcinoma (DTC) in patients who have undergone total thyroidectomy for NTD. The relationship between TSH and size of malignant nodule was investigated. Finally, we assessed whether TSH levels are related to DTC and presence of additional benign nodules. A retrospective study of 980 patients was conducted. Variables included age at diagnosis, TSH level, nodule size, gender, final histology (benign versus DTC), and type of malignancy. Malignancy was present in 261 (26.6%) patients. These patients had higher median TSH levels as compared to those with no malignancy (1.61 mU/L (0.9-2.5) versus 0.9 mU/L (0.3-1.6); p-value<0.001). TSH was higher in patients with DTC in whom the largest nodule was malignant than in patients in whom the largest nodule was benign (1.80 mU/L (1.1-2.6) versus 1.38 mU/L (0.7-2.1) respectively; p-value=0.025). A significant correlation was seen between malignant nodule size and TSH level, but not between TSH levels and size of the largest benign nodule. Our study supported an association between preoperative TSH levels and risk of DTC in patients with NTD. There was also a direct relationship between malignant nodule size and TSH levels. By contrast, no relationship was found between the size of benign nodules and TSH levels. Copyright © 2014 SEEN. Published by Elsevier Espana. All rights reserved.

    To examine the radiogenic risk of latent thyroid cancer, thyroid adenoma, colloid/adenomatous goiter and chronic thyroiditis, the date for 3821 subjects collected in the course of autopsies of atomic bomb survivors in Hiroshima from 1951 to 1985 by the Radiation Effects Research Foundation (RERF) were analyzed using a logistic model. About 80% of the autopsies were performed at RERF and the remainder at local hospitals. The frequencies of the above diseases were not associated with whether the underlying cause of death was cancer. However, note that our results may be influenced by potentially biasing factors associated with autopsy selection. The relative frequency of latent thyroid cancer (greatest dimension ≤1.5 cm but detectable on a routine microscopic slide of the thyroid gland) increased as the radiation dose increased and was about 1.4-fold greater at 1 Gy than in the 0-Gy dose group. The relative occurrence of thyroid adenoma also increased as radiation dose increased, and was about 1.5-fold greater at 1 Gy than in the 0-Gy dose group. Sex, age at the time of the bombing or period of observation did not significantly modify the radiogenic risks for thyroid adenoma or latent thyroid cancer. No statistically significant association was found between radiation exposure and the rates of colloid/adenomatous goiter and chronic thyroiditis. The possible late effect of atomic bomb radiation on the frequency of benign thyroid diseases is discussed on the basis of these data. 38 refs., 2 figs., 5 tabs

    Some patients with hyperthyroid Graves' disease have increased serum T3 and normal or even low serum T4 levels during treatment with antithyroid drugs. These patients with elevated serum T3 to T4 ratios rarely have a remission of their hyperthyroidism. The aim of this study was to investigate thyroid iodine metabolism in such patients, whom we termed T3-predominant Graves' disease. Mean thyroid radioactive iodine uptake was 51.0 +/- 18.1% ( +/- SD) at 3 h, and it decreased to 38.9 +/- 20.1% at 24 h in 31 patients with T3-predominant Graves' disease during treatment. It was 20.0 +/- 11.4% at 3 h and increased to 31.9 +/- 16.0% at 24 h in 17 other patients with hyperthyroid Graves' disease who had normal serum T3 and T4 levels and a normal serum T3 to T4 ratio during treatment (control Graves' disease). The activity of serum TSH receptor antibodies was significantly higher in the patients with T3-predominant Graves' disease than in control Graves' disease patients. From in vitro studies of thyroid tissue obtained at surgery, both thyroglobulin content and iodine content in thyroglobulin were significantly lower in patients with T3-predominant Graves' disease than in the control Graves' disease patients. Thyroid peroxidase (TPO) activity determined by a guaiacol assay was 0.411 +/- 0.212 g.u./mg protein in the T3-predominant Graves' disease patients, significantly higher than that in the control Graves' disease patients. Serum TPO autoantibody levels determined by immunoprecipitation also were greater in T3-predominant Graves' disease patients than in control Graves' disease patients. Binding of this antibody to TPO slightly inhibited the enzyme activity of TPO, but this effect of the antibody was similar in the two groups of patients

    The recommendations of the thyroid section of the Deutsche Gesellschaft fuer Endokrinologie take account of practical requirements and serve as a basis for assessing the indications of the various diagnostic methods in view of their value, expenditure, and hazards. Progress in methodology and recent scientific findings have been taken into account as well as economic aspects and the available equipment. In spite of all the possibilities offered by modern laboratory diagnosis, the diagnosis and theory of thyroid diseases should always depend on a special anamnesis and a physical examination of the patient. The measured values must agree with the patient's complaints and with clinical findings. In diagnoses involving several steps, one should always start with simple in-vitro techniques in order to spare the patient stress. Functional diagnosis of thyroid diseases are supplemented by thyroid scintiscanning with short-lived radionuclides and by thyroid cytology. Experience and precise knowledge help to 'save expense and radiation'. Of course, uncertain diagnoses and untypical findings require a more extensive use of diagnostic means than diagnosis that are more or less clinically proved.

    Objective: To study the thyroid 131 I uptake within 24 hours following 131 I therapy for Graves' disease. Methods: Eighteen hyperthyroidism patients were divided into two groups according to thyroid weight and radiotherapy dosage. Low-dose group and high-dose group received the mean dose 162.8 MBq (4.4 mCi) and 255.3 MBq (6.9 mCi), respectively. The γ ray dose rates from thyroids were measured in all patients at 1, 2, 4, 8,12 and 24 h after 131 I therapy. Results: γ ray dose rates were elevated rapidly at 1 hour and continued at high level between 2-12 h and slowly fell in 24 h after 131 I therapy. γ Rat curve of low-dose group was lower than that of high-dose group. Conclusion: There was a rapid absorption and concentration period in 1 h and slow metabolism and release period after 12 h in thyroid following radioiodine therapy of Graves' disease. The thyroids of hyperthyroidism patients displayed different γ ray curves. (author)

    Unlike the well-documented relation between radiation to the neck and development of papillary thyroid carcinoma, a causal association between radioactive iodine treatment for Graves' disease and development of thyroid malignancy is less defined. However, patients with a background of thyroid dysfunction presenting with clinically palpable thyroid nodules are followed more closely than the average population, and fine needle aspiration is recommended in such circumstances. Cytological examination of aspirates, and histologic examination of tissue provided from patients with a known history of Graves' disease, managed by radioactive iodine therapy can create a diagnostic dilemma, as the distinction between radiation effect and a malignant primary thyroid neoplasm can be very challenging. Thus, pathologists should be aware of the existence of these changes in the setting of radiation therapy for Graves' disease. Providing pathologists with appropriate clinical history of Graves' disease treated with radioactive iodine is of paramount importance in order to prevent an overdiagnosis of malignancy.

    To explore the relationship between IL-1β expression and two common autoimmune thyroid diseases: Hashimoto thyroiditis (HT) and Graves' disease (GD). qRT-PCR, Quantiglo ELISA, and flow cytometry were used to evaluate the expression levels of IL-1β in serum, peripheral blood mononuclear cells (PBMCs), and thyroid tissue samples from patients with HT or GD. Local infiltration of monocytes was assessed by immunohistochemical study of patients' thyroid tissue samples. Although no significant differences in IL-1β levels were found between samples of serum from patients with HT or GD and normal controls, we found that IL-1β mRNA and protein levels in PBMCs of HT patients were significantly higher than those of patients with GD, which were in turn higher than the level in normal controls. In addition, IL-1β mRNA was also increased in thyroid gland tissue from patients with HT compared to those with GD, and this was accompanied by increased local infiltration of monocytes into thyroid tissues. Correlation analysis of the clinical samples validated the association of high IL-1β levels with the pathogenesis of HT. Our study suggests that IL-1β may be an active etiologic factor in the pathogenesis of HT and thus present a new target for novel diagnostics and treatment.

    Moyamoya is a rare cerebrovascular disease characterized by the progressive occlusion of the intracranial carotid artery. Thyroid autoantibodies have been found to be associated with the disease, but their clinical significance has never been studied. The objective of this study was to investigate the relationship between thyroid autoantibodies and the clinical presentation of moyamoya. This is a prospective study including 37 patients with moyamoya disease (MMD) or unilateral moyamoya (uMM). Thyroid function and thyroid autoantibodies (e.g., antithyroperoxidase and antithyroglobulin) were investigated. We studied the effect of gender, age, type of moyamoya (uMM versus MMD), and thyroid autoantibodies on the clinical presentation, dichotomized into aggressive (hemorrhage, major stroke, or frequent transient ischemic attack [TIA]) and nonaggressive presentation (headache, rare TIAs, and incidental diagnosis) according to the criteria of the Research Committee on Spontaneous Occlusion of the Circle of Willis. Of the 37 patients included in the study, the autoantibodies were elevated in 9 (24.3%). An aggressive presentation occurred in 21 patients (hemorrhage in 11, major stroke in 9, frequent TIAs in 1). The autoantibodies were elevated in 8 of the 21 patients (38.09%) with an aggressive presentation and in 1 of those presenting with minor symptoms (6.2%). The presence of elevated autoantibodies was the only variable associated with an aggressive presentation in the multivariate logistic analysis (P = .048). When the serum concentration of the thyroid autoantibodies is increased, the patients have a higher risk of an aggressive presentation. Our results support the hypothesis that activation of immune-mediated processes affects the moyamoya physiopathology. Copyright © 2018 National Stroke Association. Published by Elsevier Inc.

    Background: Preoperative evaluation of recurrent laryngeal nerve function is important in the context of thyroid surgery. Transcutaneous ultrasound may be useful to visualize vocal fold movement when evaluating thyroid disease. Methods: A 7–18 MHz linear array transducer was placed transversely on the midline of the thyroid cartilage at the anterior neck of patients with thyroid disease. The gray-scale technique was used, with the scan setting for the thyroid gland. Results: Between August 2008 and March 2010, 705 patients, including 672 patients with normal vocal fold movement and 33 patients with vocal fold paralysis were enrolled. They included 159 male and 546 female patients. Their ages ranged from 10 to 88 years. Vocal fold movement could be seen by ultrasound in 614 (87%) patients, including 589 (88%) patients with normal vocal fold movement and 25 (76%) patients with vocal fold paralysis (p = 0.06). The mean age of patients with visible and invisible vocal fold movement was 46.6 and 57.9 years old, respectively (p = 0.001). Ultrasound was able to see vocal fold movement in 533 (98%) female patients but only in 81 (51%) male patients (p = 0.001). Among the patients with vocal fold paralysis, ultrasound revealed palsied vocal folds in 17 of 18 (94%) female patients but in only 8 of 15 (53%) male patients (p = 0.01). Conclusion: Transcutaneous ultrasound represents an alternative tool to evaluate vocal fold movement for more than 85% of patients with thyroid disease, including more than 90% of female patients and about half of male patients.

    The aim of this retrospective study was the evaluation of a TcTUs (global technetium-99m pertechnetate thyroid uptake under suppression)-based approach in 370 patients with thyroid autonomy (Plummer's disease) treated by radioiodine therapy (RIT) under standardised conditions. The analysis included 370 patients (309 females, 61 males; mean age 64±11.6 years) treated for thyroid autonomy [unifocal (UFA), 36.8%; multifocal (MFA), 55.7%; disseminated (DISA), 7.6%]. During RIT all patients were under thyroid suppression (TSH 0.5 μU/l and/or TcTUs 4 μU/ml). A dose of 350-450 Gy to the autonomous tissue resulted in a success rate of 97% in the UFA group and 81% in the MFA/DISA group. Decrease in total thyroid volume and TcTUs did not differ significantly between successfully treated patients and patients with persistent autonomy. Multivariate analysis of all 370 patients identified four independent factors that negatively influenced the therapeutic success: high pretherapeutic thyroid volume (P=0.0001; odds ratio: 1.017), high pretherapeutic TcTUs values (P=0.0001; odds ratio: 1.378), multifocal/disseminated autonomy (P=0.0056; odds ratio: 3.245) and low target dose (P=0.017; odds ratio: 0.997). It is concluded that the high success rate in the treatment of UFA indicates the concept of TcTUs-based RIT to be valid, but that in the therapy of MFA/DISA the target se has to be corrected if the total thyroid volume exceeds a critical threshold.

    OBJECTIVE--To estimate individual radiation doses and current thyroid disease status for a previously identified cohort of 4818 schoolchildren potentially exposed to fallout from detonations of nuclear devices at the Nevada Test Site between 1951 and 1958. DESIGN--Cohort analytic study. SETTING--Communities in southwestern Utah, southeastern Nevada, and southeastern Arizona. PARTICIPANTS--Individuals who were still residing in the three-state area (n = 3122) were reexamined in 1985 and 1986, and information on the subjects' and their mothers' milk and vegetable consumption during the fallout period was obtained by telephone interview (n = 3545). After exclusions to eliminate missing data and confounding factors, 2473 subjects were available for analysis. MAIN OUTCOME MEASURES--Individual radiation doses to the thyroid were estimated by combining consumption data with radionuclide deposition rates provided by the US Department of Energy and a survey of milk producers. Relative risk models adjusted for age, sex, and state were fitted using maximum likelihood to period prevalence data for thyroid carcinomas, neoplasms, and nodules. RESULTS--Doses ranged from 0 mGy to 4600 mGy, and averaged 170 mGy in Utah. There was a statistically significant excess of thyroid neoplasms (benign and malignant; n = 19), with an increase in excess relative risk of 0.7% per milligray. A relative risk for thyroid neoplasms of 3.4 was observed among 169 subjects exposed to doses greater than 400 mGy. Positive but nonsignificant dose-response slopes were found for carcinomas and nodules. CONCLUSIONS--Exposure to Nevada Test Site-generated radioiodines was associated with an excess of thyroid neoplasms. The conclusions are limited by the small number of exposed individuals and the low incidence of thyroid neoplasms

  8. The onset of systemic lupus erythematosus and thyroid dysfunction following graves’ disease - a case report and literature review

    Full Text Available Introduction. Graves’ disease is a multifactorial autoimmune thyroid disease, with the presence of typical circulating autoantibodies that can activate the thyroid hormone receptors, resulting in hyperthyroidism, goiter, and ophthalmopathy. Systemic lupus erythematosus is a multi-systemic autoimmune disease that involves almost all the organs of the human body and is characterized by autoantibodies formation. Several studies have reported that autoimmune thyroid and rheumatic disorders can present an unusual relationship. Case Outline. We report a case of a middle-aged woman who presented with systemic lupus erythematosus one year after being diagnosed with Graves’ disease. Prednisone and cyclophosphamide were administered to control the development of systemic lupus erythematosus. Furthermore, a percutaneous thyroid biopsy was performed for further confirmation of Graves’ disease. Methimazole instead of propylthiouracil was added into the therapeutic scheme. A month later, the patient’s clinical manifestation and laboratory tests got significant improvement, except that new thyr o id dysfunction appeared opposite to the original one. The administration of anti-thyroid drug was discontinued. With a period of decreased administration of prednisone, the patient’s thyroid function gradually got back to normal levels without any levothyroxine replacement. Conclusion. In conclusion, the clinical use of prednisone and antithyroid drugs may result in instability of the hypothalamus-pituitary-thyroid axis, and thyroid function should be carefully monitored in such patients.

  9. Thyroid peroxidase: evidence for disease gene exclusion in Pendred's syndrome.

    Pendred's syndrome is an association between congenital neurosensory deafness and goitre with abnormal discharge of iodide following perchlorate challenge, indicating a defect of iodide organification. Although Pendred's syndrome may cause up to 7.5% of all cases of congenital deafness, the molecular basis of the association between the hearing loss and the thyroid organification defect remains unknown. We chose to investigate the role of the thyroid peroxidase (TPO) gene as the genetic defect in Pendred's syndrome. A highly informative variable number tandem repeat (VNTR), located 1.5 kb downstream of exon 10 of the TPO gene, was used to search for genetic linkage in multiple sibships affected by Pendred's syndrome. Seven kindreds were recruited from the UK, each with at least two affected members. We have also examined a large inbred Israeli family with two affected offspring and five unaffected children. Individuals were assigned affected status based on the characteristic clinical features of Pendred's syndrome, namely the presence of congenital sensorineural hearing loss and the appearance in early life of a goitre. Additionally, at least one affected member from each sibship had a characteristic positive perchlorate discharge test (Morgans & Trotter, 1958). PCR amplification of genomic DNA at the TPO VNTR allowed assignment of genotypes to each individual and the calculation of a two-point LOD score. In six of the nine sibships analysed we found obligatory recombination between TPO and Pendred's syndrome. Non-complementation observed in affected parents with an affected offspring excluded TPO in an affected sibship with genotype sharing and supports a hypothesis of genetic homogeneity for Pendred's syndrome. In two sibships, mutation of the TPO gene as the cause of Pendred's syndrome could not be excluded. These data suggest that defects at the thyroid peroxidase locus on chromosome 2 are not the major cause of Pendred's syndrome.

    The Department of Energy Richland Operations Office is in the process of reengineering its Hanford Site operations. There is a need to fundamentally rethink and redesign environmental restoration and waste management processes to achieve dramatic improvements in the quality, cost-effectiveness, and timeliness of the environmental services and products that make cleanup possible. Hanford is facing the challenge of reengineering in a complex environment in which major processes cuts across multiple government and contractor organizations and a variety of stakeholders and regulators have a great influence on cleanup activities. By doing the upfront work necessary to allow effective reengineering, Hanford is increasing the probability of its success.

    In most cases, the histopathologic and cytologic distinction between Graves' disease and papillary thyroid carcinoma is relatively easy, but on occasion Graves' disease may simulate a thyroid papillary carcinoma. For example, papillary fronds with fibrovascular cores may be present in both Graves' disease and papillary carcinoma. p27kip1 (p27) is a cyclin-dependent kinase inhibitory protein that has been shown to be an independent prognostic factor in a variety of human tumors. Our previous studies of p27 expression in hyperplastic and neoplastic endocrine lesions showed that the level of p27 was quite different in these two conditions. To determine if this distinction could also be made between Graves' disease and papillary carcinoma, we analyzed expression of p27 and other cell cycle proteins in a series of cases of Graves' disease with papillary hyperplasia and a series of papillary thyroid carcinomas. Formalin-fixed paraffin-embedded tissues from 61 randomly selected patients with thyroid disease, including 29 cases of Graves' disease with papillary architectural features and 32 cases of papillary carcinoma, were analyzed for expression of p27, Ki-67, and DNA topoisomerase II alpha (topo II alpha) by immunostaining. The distribution of immunoreactivity was analyzed by quantifying the percentage of positive nuclei that was expressed as the labeling index (LI) plus or minus the standard error of the mean. The papillary hyperplasia of Graves' disease had a p27 LI of 68.2 +/- 3.1 (range, 24 to 88), whereas papillary carcinomas had a LI of 25.6 +/- 2.5 (range, 12 to 70) (P hyperplasia in Graves' disease and papillary carcinoma. These results indicate that p27 protein expression is significantly higher in papillary hyperplasia of Graves' disease compared to papillary carcinoma, which may be diagnostically useful in difficult cases.

    The report describes the development and summarizes the results of the project Cancer incidence and thyroid disease among Estonian Chernobyl clean-up workers. One of the goals of the report is to give research protocols and questionnaires for researchers involved in other studies. Eight previously published articles are also included summarizing the results. The development of the collaboration work of the project is described in the introduction of the report. Epidemiological methods are described in an article complemented by the protocol and English version of the questionnaire administered to all cleanup workers, as well as the data collection form of the thyroid study. The results from biological biodosimetry using both glycophorin A and FISH methods have shown that the radiation doses received by the Chernobyl cleanup workers were relatively low. Thyroid nodularity was not associated with any radiation exposure characteristic in the thyroid screening study. Estonian Chernobyl cleanup workers were followed up for cancer incidence through the Estonian Cancer Registry. No cases of leukemia or thyroid cancer were observed by the end of 1993. It is too early to observe possible effect on other types of cancer. However, mortality from suicides was increased compared with general population. Further follow-up and the extension to other Baltic countries in the future will undoubtedly strengthen the study.

    Full Text Available Introduction: There are many adverse effects that have been described for isotretinoin. To the best of our knowledge, this is the first report of a possible association of oral isotretinoin intake with autoimmune thyroiditis and ocular myasthenia gravis (OMG. Case Presentation: A 19-year-old Caucasian male, who had used oral isotretinoin for severe acne disease for the previous six months, was referred to our clinic. He had a three-week history of diplopia and variable bilateral ptosis. Physical examination showed moderate periorbital edema and limitations of up- and down-gaze in the left eye. Laboratory findings and thyroid ultrasound were consistent with autoimmune thyroiditis. Antithyroid therapy did not relieve the clinical symptoms. Concomitant OMG was suspected. Variable ptosis and a positive response to oral prednisolone of 40 mg/day and pyridostigmine of 360 mg/day supported the diagnosis of concomitant autoimmune thyroiditis and OMG. Conclusion: Autoimmune disorders may be triggered by oral isotretinoin treatment. Clinicians prescribing isotretinoin should be aware of the possible association between isotretinoin intake and concomitant autoimmune thyroiditis and OMG.

    The study deals with methods of treatment of benign thyroid affections: diffuse hyperthyroidism, autonomous adenoma, euthyreotic struma. 70% of the patients examined require resective therapy for diffuse hyperthyroidism. In the majority of the cases radio-iodine resection is the method to be chosen. The risk of an eventual X-ray cancer is smaller than the operation mortality. As far as children and adolescents are concerned, 131-iodine therapy is generally not advisable because of the carcinogenic risk which might be heightened. The autonomous adenoma can be eliminated without any problems by using 131-iodine. In case of a large adenoma with considerable regressive changes operation should be preferred. The therapeutic measures in the case of a struma mainly depend on the question if there are any clinical symptoms or any signs indicating an increased risk of malignancy. In case of mechanical complaints caused by a struma nodosa without important regressive changes parenchyma can be reduced by administering 131-iodine once or several times. The reduction of the thyroid function to the middle or lower limit of the normal range in case of euthyreosis is carried out by 131-iodine administration. (GSE) [de

    An International Conference entitled 'One decade after Chernobyl: Summing up the consequences of the accident' was held at the Vienna from 8 to 12 April 1996. The aim of conference was to seek a common and conclusive understanding of the nature and magnitude of the consequences of the Chernobyl accident. It was concluded that a highly significant increase in the incidence of thyroid cancer among those persons in the affected areas who were children in 1986 is the only clear evidence to data of a public health impact of radiation exposure as a result of the Chernobyl accident and both temporal and geographical distributions clearly indicate a relationship of the increase in incidence to radiation exposure due to the Chernobyl accident. To clarify the relationship between thyroid cancer and radioactive fallout more clearly, a long term prospective study (case-control/cohort) should be conducted in the highly risk groups and the analysis of accurate estimation of exposure dose to external and/or internal radiation is needed.

    Pathological disturbances of thyroid hormones is associated with central and peripheral nervous system disturbances. The aim of this study is to evaluate median nerve stimulated somatosensory evoked potential (SEP) and blink reflex of thyroid patients (hypo and hyperthyroidism). Median SEP was performed in 40 patients (21 with hyperthyroidism and 19 with hypothyroidism). We evaluated the latencies of N9, N11, N13, P9, P11, P14, N20 and P25 waves and the N9-N20, N9-N13, N13-N20 and P14-N20 interpeak latencies. We compared the results of patients with the control group (26 persons). We found that the N20 latency was longer in patients with hyperthyroidism than in the control group and the difference was statistically significant. There was not any statistically significant difference regarding the N9, N11, N13, P9, P11, P14, N20 and P25 latencies and the N9-N20, N9-N13, N13-N20 and P14-N20 interpeak latencies between hypothyroid patients and controls. We performed the blink reflex study in 28 of 40 patients (14 patients with hyperthyroidism and 14 patients with hypothyroidism). Comparing the R1, R2, CR2 (contralateral R2) latencies and durations of the patients and controls, we found that R2 and CR2 duration was shorter in patients with hyperthyroidism. This difference was statistically significant.

    Overweight and diseases connected with it are an increasing problem in children and adolescents. Thyroid disease leads to a change of weight - in hyperthyroidism body mass is reduced whereas in hypothyroidism it is increased. It is emphasized that changes in hormones such as peptide levels are in close relationship with the regulation of body mass. Nesfatin-1 is a recently described anorexigenic peptide produced by the brain. Nesfatin-1 also reduces body weight gain, suggesting a role as a new modulator of energy balance. Excess nesfatin in the brain leads to a loss of appetite, less frequent hunger, a `sense of fullness´, and a drop in body fat and weight. A lack of nesfatin-1 in the brain leads to an increase of appetite, more frequent episodes of hunger, an increase of body fat and weight, and the inability to `feel full´. Aim of the study was to evaluate nesfatin-1 levels in young patients with untreated Graves´ disease, subclinical Hashimoto´ thyroiditis, and in healthy children. The study group formed 78 patients of the Outpatient Endocrinology Clinic of Pediatrics, Endocrinology, Diabetology with Cardiology Division. In all the patients, nesfatin level was analyzed by the ELISA´s method. In the group with hyperthyroidism in Graves´ disease lower levels of nesfatin-1 were found compared to the group of healthy children (19.37 vs 32.96 ng/ml; phyperthyroidism, but lower compared to the group of healthy children (20.35 vs 32.96 ng/ml; NS). On the other hand, nesfatin-1 levels were lower in children with untreated subclinical hypothyroidism in Hashimoto´s thyroiditis compared to the group of healthy children (17.2 vs32.96 ng/ml; p<0.002). After treatment of L-thyroxine lower levels of nesfatin-1 were found compared to the control group (14.5 vs 32.96 ng/ml; NS). No relationship between nesfatin-1 and thyroid hormones was observed. It might be that disturbances in thyroid hormones in thyroid diseases do not have an essential effect on changes of nesfatin-1

    In-vivo diagnoses of thyroid diseases can be carried out using /sup 123/I, /sup 131/I, and /sup 99/sup(m)Tc-pertechnetate. For the thyroid scintiscan, /sup 99/sup(m)Tc-pertechnetate or /sup 123/I are used. Some functional parameters can be determined using /sup 99/sup(m)Tc-pertechnetate, but iodine is more accurate, so that thyroid clearance examinations with /sup 123/I are rapidly gaining importance. However, the iodine turnover in the thyroid can only be determined by a several-days' test using /sup 131/I. The available techniques of diagnosis are employed in several steps. Most thyroid diseases can already be diagnosed on the basis of the hormone parameters and a thyroid scan; otherwise, a TRH test and suppression and functional studies will be necessary. Treatment of enthyroid struma is limited to inoperable cases with functional blockage or compression of the trachea. In the treatment of diffuse hyperthyroidism, doses should be exact enough to counteract the hyperthyroid metabolism without inducing hypothyroidism. With exact doses, a second radioiodine therapy will only be necessary in about 40% of all cases. High doses should not be applied in the treatment of hyperthyroidism unless it is a case of excessive clinical hyperthyroid somatics as the risk of hypothyroidism is high. The diagnostic problem of autonomous adenoma is the highly varying hormone activity. The intention of radioiodine therapy here is a functional elimination of the autonomous adenoma. Radioiodine resection is indicated in cases where there are several small autonomous adenomas or where the operability of the patient is limited.

    The purpose of the Hanford Environmental Dose Reconstruction (HEDR) Project is to estimate radiation doses from Hanford Site operations since 1944 to representative individuals. The primary objective of work to be performed through May 1994 is to determine the project's appropriate scope: space, time, radionuclides, pathways and representative individuals; determine the project's appropriate level of accuracy/level of uncertainty in dose estimates; complete model and data development; and estimate doses for the Hanford Thyroid Disease Study and representative individuals. A major objective of the HEDR Project is to estimate doses to the thyroid of individuals who were exposed to iodine-131. A principal pathway for many of these individuals was milk from cows that ate vegetation contaminated by iodine-131 released into the air from Hanford facilities. The plan for June 1992 through May 1994 has been prepared based on activities and budgets approved by the Technical Steering Panel (TSP) at its meetings on January 7--9, 1993 and February 25--26, 1993. The activities can be divided into three broad categories: (1) computer code and data development activities, (2) calculation of doses, and (3) technical and communication support to the TSP and the TSP Native American Working Group (NAWG). The following activities will be conducted to accomplish project objectives through May 1994

    Records describing wells located on or near the Hanford Site have been maintained by Pacific Northwest Laboratory and the operating contractor, Westinghouse Hanford Company. In support of the Ground-Water Surveillance Project, portions of the data contained in these records have been compiled into the following report, which is intended to be used by those needing a condensed, tabular summary of well location and basic construction information. The wells listed in this report were constructed over a period of time spanning almost 70 years. Data included in this report were retrieved from the Hanford Envirorunental Information System (HEIS) database and supplemented with information not yet entered into HEIS. While considerable effort has been made to obtain the most accurate and complete tabulations possible of the Hanford Site wells, omissions and errors may exist. This document does not include data on lithologic logs, ground-water analyses, or specific well completion details

    The TSH and T 3 response to synthetic TRH was evaluated in two groups of patients: normal and with Chagas' disease, from the urban area of Sao Paulo (Brazil). Plasma T 4 , PBI and TSH values were within the normal range, when compared with those found in the controls: So were the thyroid uptakes of 2 and 24 hours; the basal levels of T 3 where within the normal range except in three subjects whose values were higher than normal. After TRH administration the amount of TSH secretion in patients with Chagas' disease was increased when compared to normal ones, while T 3 secretion was unaltered. It is suggested that in the Chagas' disease there is an increase in the pituitary TSH, while the thyroid reserve is preserved. This increase could be due to a difference in the regulation rate of TRH, which is determined by the neuronal degeneration caused by the disease itself. (author) [pt

    Inorganic pyrophosphatase (PPase) controls the level of inorganic pyrophosphate produced by biosynthesis of protein, RNA, and DNA. Thus, PPase is essential for life. PPase expression is unclear in the thyroid. We cloned a new human PPase, phospholysine phosphohistidine inorganic pyrophosphate phosphatase (LHPPase), and established a rabbit polyclonal anti-LHPPase antibody. This is First study to determine the PPase expression by immunohistochemistry and Western blot. Intranuclear LHPPase expression of thyrocytes was enhanced most prominently in Graves' disease and autonomously functional thyroid nodule. To estimate a regulating factor of subcellular localization of LHPPase, we examined its expression of Graves' disease-derived thyrocytes in vitro with the disease-originated serum. Nuclear expression of LHPPase was lost in cultured thyrocytes even with the serum, while its cytoplasmic expression was retained. The data suggest that increased expression of LHPPase is associated with hyperthyroidism. Intranuclear expression of LHPPase may not be regulated by Graves' disease-derived serum factors

    Full Text Available BackgroundLittle is known regarding disease-specific mortality of differentiated thyroid cancer (DTC patients and its risk factors in Korea.MethodsWe retrospectively reviewed a large multi-center cohort of thyroid cancer from six Korean hospitals and included 8,058 DTC patients who underwent initial surgery between 1996 and 2005.ResultsMean age of patients at diagnosis was 46.2±12.3 years; 87% were females. Most patients had papillary thyroid cancer (PTC; 97% and underwent total thyroidectomy (85%. Mean size of the primary tumor was 1.6±1.0 cm. Approximately 40% of patients had cervical lymph node (LN metastases and 1.3% had synchronous distant metastases. During 11.3 years of follow-up, 150 disease-specific mortalities (1.9% occurred; the 10-year disease-specific survival (DSS rate was 98%. According to the year of diagnosis, the number of disease-specific mortality was not different. However, the rate of disease-specific mortality decreased during the study period (from 7.7% to 0.7%. Older age (≥45 years at diagnosis, male, follicular thyroid cancer (FTC versus PTC, larger tumor size (>2 cm, presence of extrathyroidal extension (ETE, lateral cervical LN metastasis, distant metastasis and tumor node metastasis (TNM stage were independent risk factors of disease-specific mortality of DTC patients.ConclusionThe rate of disease-specific mortality of Korean DTC patients was 1.9%; the 10-year DSS rate was 98% during 1996 to 2005. Older age at diagnosis, male, FTC, larger tumor size, presence of ETE, lateral cervical LN metastasis, distant metastasis, and TNM stages were significant risk factors of disease-specific mortality of Korean DTC patients.

    Thyroid uptake of (99m)Tc-pertechnetate is a useful way to determine the cause of thyrotoxicosis. In daily clinical practice, (99m)Tc-pertechnetate uptake is used to discriminate between Graves' disease and painless thyroiditis when clinical information is not enough to make the distinction. However, since the optimal cutoff value of (99m)Tc-pertechnetate uptake has not yet been elucidated, our aim was to determine this value. We recruited patients with thyrotoxicosis in whom (99m)Tc-pertechnetate uptake was measured in clinical settings between 2009 and 2013. Three experienced endocrinologists (who were blinded to the value of (99m)Tc-pertechnetate uptake and initial treatment) diagnosed the cause of thyrotoxicosis based on thyrotropin, free triiodothyronine, free thyroxine, and thyrotropin receptor antibody levels, and by ultrasound findings and using images of thyroid uptake of (99m)Tc-pertechnetate without the actual values. Ninety-four patients diagnosed as having Graves' disease or painless thyroiditis were finally included. According to the diagnosis, the optimal cutoff value of (99m)Tc-pertechnetate uptake was determined by receiver operating characteristics analysis. A cutoff value of 1.0% provided optimal sensitivity and specificity of 96.6% and 97.1%, respectively. Then, its validity was confirmed in 78 patients with confirmed Graves' disease or painless thyroiditis diagnosed at another institute. Applying this cutoff value to the patients with thyrotoxicosis revealed positive and negative predictive values for Graves' disease of 100% and 88.9%, respectively. In conclusion, a cutoff value for (99m)Tc-pertechnetate uptake of 1.0% was useful to discriminate between Graves' disease and painless thyroiditis.

    Full Text Available Background. Studies in several ethnic groups reported high incidence of elevated levels of immunoglobulin E (IgE in patients with autoimmune thyroid diseases (ATD, especially in patients with Graves’ disease. Objective. To study association between serum levels of IgE and thyroid stimulating hormone receptor antibodies (TRAb in Albanian patients with ATD. Material and Methods. Study was performed in 40 patients with Graves’ disease, 15 patients with Hashimoto’s thyroiditis, and 14 subjects in the control group. The IgE levels were measured by immunoradiometric assay, whereas the TRAb levels were measured by radioreceptor assay. Results. In all groups of subjects the IgE levels were within reference values (<200 kIU/L. Significant difference in mean concentration of IgE was found between two groups of Graves’ disease patients, and those with normal and elevated TRAb levels (22.57 versus 45.03, P<0.05. Positive correlation was found between TRAb and IgE only in Graves’ disease patients (r=0.43, P=0.006. Conclusion. In Albanian patients with ATD there is no elevation of IgE levels. This could be the result of low prevalence of allergic diseases in Albanian population determined by genetic and environmental factors.

    Cardiac, thyroid and pulmonary function were evaluated in 25 patients aged 35 years or under, treated for Hodgkin's disease by mantle radiotherapy 5-16 years previously. No patient had symptoms of heart disease. Although thallium myocardial perfusion scintigraphy was normal in all patients, abnormalities of myocardial function were detected in 6 (24%) patients using gated equilibrium rest and exercise radionuclide ventriculography. Resting left ventricular ejection fraction (LVEF) was abnormal in 1 patient, and in 3 patients there was an abnormal LVEF response to exercise. All 6 patients had right ventricular dilatation. Apical hypokinesia was present in 4 of these patients. A small asymptomatic pericardial effusion was detected by M-Mode echocardiography in only 2 (8%) patients. Twenty-three (92%) patients had evidence of abnormal thyroid function. Two (8%) patients had become clinically hypothyroid. Serum TSH was elevated in 13 (52%) patients and TRH stimulation test was abnormal in a further 10 (40%) patients in whom TSH was normal. Pulmonary function studies showed a moderate decrease in diffusing capacity (72% of predicted) and a minor reduction in lung volume. Although a high incidence of cardiac, thyroid and pulmonary abnormalities was detected, only the 2 patients who had become hypothyroid were symptomatic. Modification of the irradiation technique may reduce the incidence of cardiac abnormalities, but is unlikely to alter significantly the thyroid or pulmonary sequelae

    Full Text Available Introduction: The prevalence of autoimmune thyroid disease (AITD is 10–12% in the general population worldwide. Among various disorders co-existing with AITD, the concomitance of celiac disease (CD with AITD results in poor absorption of thyroid medications and results in higher doses of the same. Institution of gluten-free diet (GFD in this cohort helps reduce medication doses. Aim: To screen patients with AITD for the presence of celiac autoimmunity (CA. Materials and Methods: A total of 280 consecutive patients with AITD attending the thyroid Out-patient Department of a tertiary care hospital were screened for the presence of tissue transglutaminase antibodies (immunoglobulin A tissue transglutaminase. Those with a positive titer (but < 10 times the upper limit of normal underwent upper gastrointestinal endoscopy and duodenal mucosal biopsy for the diagnosis of CD, followed by institution of GFD in confirmed cases. Results: Of a total of 280 (182 females and 98 males patients with AITD screened, 24 (8.6% turned out to be positive for CA. Of 24 (8.6%, 15 (8.24% females and 9 (9.18% males were positive for CA. There was no statistically significant difference in the thyroxine doses required for normalization of thyroid function and the weight of the patients in CA positive and CA negative patients. Conclusions: The prevalence of CD in patients with AITD is much greater than in the general population. This forms the basis for screening patients with AITD for presence of CD.

    Full Text Available Abstract Introduction This paper concerns the analysis of the features obtained from thyroid ultrasound images in left and right transverse and longitudinal sections. In the image analysis, the thyroid lobe is treated as a texture for healthy subjects and patients with Hashimoto’s disease. The applied methods of analysis and image processing were profiled to obtain 10 features of the image. Then, their significance in the classification was shown. Material In this study, the examined group consisted of 29 healthy subjects aged 18 to 60 and 65 patients with Hashimoto's disease. For each subject, four ultrasound images were taken. They were all in transverse and longitudinal sections of the right and left lobe of the thyroid, which gave 376 images in total. Method 10 different features obtained from each ultrasound image were suggested. The analyzed thyroid lobe was marked automatically or manually with a rectangular element. Results The analysis of 10 features and the creation for each one of them their own decision tree configuration resulted in distinguishing 3 most significant features. The results of the quality of classification show accuracy above 94% for a non-trimmed decision tree.

    Mixed connective tissue disease (MCTD) is a connective tissue disorder characterized by high titers of distinct antibodies: U1 ribonucleoprotein with clinical features seen in systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), dermatomyositis (DM), polymyositis, and scleroderma. The association of SLE and DM with various cancers of the thyroid has been reported in the literature. However, there have been no reports associating MCTD with thyroid cancer. We present a 58-year-old woman diagnosed with MCTD with co-morbid interstitial lung disease that has remained stable for 10 years, who developed papillary thyroid carcinoma (PTC) 10 years after initial diagnosis. We theorize that: 1) MCTD may have been a primary diagnosis complicated by PTC, or 2) MCTD may have been an initial presentation of paraneoplastic syndrome of silent PTC, because her symptoms of MCTD significantly improved after total thyroidectomy. To the best of our knowledge, this is the first case report to associate MCTD with PTC. It highlights the importance of maintaining a high index of suspicion for thyroid malignancy in MCTD patients.

    In this report we describe an unusual patient with hyperfunctioning thyroid adenoma in whom percutaneous ethanol injection (p.e.i.) therapy was followed by typical Graves' disease. His history revealed the presence of a sister with Hashimoto's thyroiditis. 99-mTc thyroid scintiscan showed focal uptake in the nodule, with suppression of extranodular parenchyma. P.e.i. therapy was followed by the development of severe hyperthyroidism. One month after a second p.e.i. cycle, recurrence of hyperthyroidism associated with diffuse 99-mTc uptake by the gland was observed. TSH-receptor and thyroglobulin autoantibodies were undetectable before p.e.i. therapy, appeared during the first cycle, and showed a further increase after the second p.e.i. therapy cycle. Though spontaneous switch to Graves' disease cannot be excluded in patients with toxic nodules, the massive release of thyroid materials from follicular cells, among these TSH-receptor antigenic components partially denatured by ethanol, may indeed trigger an autoimmune response to the TSH-receptor, thus accounting for this observation. Patients with possible autoimmune disposition, as selected by familiar history and/or laboratory markers should be carefully monitored during p.e.i. treatment.

    Full Text Available Introduction: Simultaneous occurrence of Hashimoto′s thyroiditis (HT, and Graves′ disease (GD is rare. Aims and Objectives: We report a case of simultaneous occurrence of GD and HD, at presentation. Case Report: A 60-year-old lady presented with tremulousness of hands, palpitation, and excessive sweating. She had a history of weight loss and neck-swelling. Her weight was 46 kg, BMI 17, afebrile, regular pulse rate of 110/min with fine tremor in hands. Thyroid gland was symmetrically enlarged, firm, without any bruit, but mildly tender with lobular surface. There were no occular manifestations. Initial thyroid function tests (TFT revealed: T3: 3.80 ng/ml (0.80-2.10, T4: 12.40 ug/dl (5.10-12, thyroid stimulating hormone (TSH: 0.20 μU/L (0.70-5. Her anti thyroperoxidase (TPO antibody: 374 IU/ml (normal [nl.] <35 and TSH receptor antibody: 15 U/L (nl. <1 were both strongly positive. Ultrasonogram of thyroid revealed a hypoechoic enlarged gland. 99mTc pertechnetate scan showed an enlarged gland with increased uptake of radiocontrast: 17% (nl. 0.4-4% with some patchy defects in both lower poles. Thyroid fine needle aspiration cytology (FNAC showed sheets of Hurthle cells with abdunce of lymphocytes indicating HT. She was observed on beta blockers. Repeat TFT, 3 months later showed: T3: 4.20 ng/ml, T4: 14.40 ug/dl, TSH: 0.001 μU/L, with increased uptake on repeat scan. Conclusion: HT rarely occurs following GD. Our case of an elderly lady with no eye signs, lobular, firm tender goiter with patchy uptake in both lower poles on Tc99m scan were odd points in diagnosing isolated GD. FNAC confirmed simultaneous HD with GD.

    Riedel's thyroiditis is a chronic fibrosing disorder of unknown etiology often associated with "multifocal fibrosclerosis." IgG4-related systemic disease is characterized by IgG4+ plasma cell infiltration and fibrosis throughout many organs. We hypothesized that Riedel's thyroiditis is part of the IgG4-related systemic disease spectrum. We searched our institution's pathology database using the terms "Riedel's," "struma," "thyroid," and "fibrosis," and identified 3 cases of Riedel's thyroiditis. Riedel's thyroiditis was diagnosed if there was a fibroinflammatory process involving all or a portion of the thyroid gland, with evidence of extension of the process into surrounding tissues. Immunohistochemical stains for IgG4 and IgG were performed. The histopathologic and immunohistochemical features of each involved organ were evaluated. The clinical features of one patient with multiple organ system disease were described. All 3 thyroidectomy samples stained positively for IgG4-bearing plasma cells. One patient had extensive extrathyroidal involvement diagnostic of IgG4-related systemic disease, including cholangitis, pseudotumors of both the lung and lacrimal gland, and a lymph node contiguous to the thyroid that stained intensely for IgG4+ plasma cells. The histologic features of all organs involved were consistent with IgG4-related systemic disease. Patient 3 had 10 IgG4+ plasma cells per high-power field initially, but rebiopsy 2 years later demonstrated no IgG4+ plasma cells. That patient's second biopsy, characterized by fibrosis and minimal residual inflammation, further solidifies the link between IgG4-bearing plasma cells in tissue and the histologic evolution to Riedel's thyroiditis. Riedel's thyroiditis is part of the IgG4-related systemic disease spectrum. In many cases, multifocal fibrosclerosis and IgG4-related systemic disease are probably the same entity.

  1. Use of the recursive-rule extraction algorithm with continuous attributes to improve diagnostic accuracy in thyroid disease

    Full Text Available Thyroid diseases, which often lead to thyroid dysfunction involving either hypo- or hyperthyroidism, affect hundreds of millions of people worldwide, many of whom remain undiagnosed; however, diagnosis is difficult because symptoms are similar to those seen in a number of other conditions. The objective of this study was to assess the effectiveness of the Recursive-Rule Extraction (Re-RX algorithm with continuous attributes (Continuous Re-RX in extracting highly accurate, concise, and interpretable classification rules for the diagnosis of thyroid disease. We used the 7200-sample Thyroid dataset from the University of California Irvine Machine Learning Repository, a large and highly imbalanced dataset that comprises both discrete and continuous attributes. We trained the dataset using Continuous Re-RX, and after obtaining the maximum training and test accuracies, the number of extracted rules, and the average number of antecedents, we compared the results with those of other extraction methods. Our results suggested that Continuous Re-RX not only achieved the highest accuracy for diagnosing thyroid disease compared with the other methods, but also provided simple, concise, and interpretable rules. Based on these results, we believe that the use of Continuous Re-RX in machine learning may assist healthcare professionals in the diagnosis of thyroid disease.

    To assess the activity and clinical course of Graves' disease with diffusion-weighted magnetic resonance (MR) imaging. Fifty-one patients with Graves' disease and 25 volunteers underwent diffusion MR imaging of the thyroid gland using a single shot echo-planar imaging with b-factor of 0, 300 and 600 second/mm(2). The apparent diffusion coefficient (ADC) values of the thyroid gland were calculated. Patients with active Graves' disease included untreated patients at initial diagnosis (n = 12), patients under antithyroid drugs (n = 11), and patients in relapse after withdrawal of therapy (n = 13). Patients with inactive disease had a remission of hyperthyroidism (n = 15). The mean ADC values of thyroid gland with active Graves' disease was 0.65 +/- 0.03 x 10(-3) mm(2)/second in patients at initial diagnosis, 0.81 +/- 0.02 x 10(-3) mm(2)/second in patients undergoing antithyroid drug and 0.72 +/- 0.07 x 10(-3) mm(2)/second in patients with relapse of hyperthyroidism. The mean ADC of patients with remission was 0.94 +/- 0.03 x 10(-3) mm(2)/second and for normal volunteer was 1.06 +/- 0.08 x 10(-3) mm(2)/second. There was significant difference in the ADC value of patients with active disease and remission (P = .001). The cutoff ADC value used for differentiating patients with active disease from patients with remission was 0.82 x 10(-3) mm(2)/second. The mean ADC value of thyroid gland had positive correlation with thyroid-stimulating hormone (r = 0.87, P = .001) and negative correlation with serum T4 (r = -0.82, P = .001) and serum T3 (r = -0.71, P = .001). The ADC value of the thyroid gland is a promising non invasive parameter for diagnosis of different clinical stages of Graves' disease. Hence it can be used to assess the activity and predict the outcome of patients during and after medical treatment. Crown Copyright (c) 2010. Published by Elsevier Inc. All rights reserved.

    Highly sensitive radioimmunoassays of hTSH sub-units were developed. The hormone preparations were labelled with 125-iodine according to a modified chloramine -T method, and purified by chromatography using biogel P6 and P60. Rabbit antisera were used as antibodies. Separation of the antibody-bound and of the free antigens was carried out via the double antibody method. The antiserum required for this purpose was obtained from a goat. The sensitivity of the assay was influenced by changing the protein content of the buffer, the incubation volume, the tracer amounts, the incubation time and the incubation temperature. For hTSH-α, the lowest detectable limit was found to be 50 pg/ml, for hTSH-#betta# 20 pg/ml. Thus, the sub-units could be determined for 98% of the patients under review. The #betta#-TSH radioimmunoassay is largely specific, TSH cross-reacts to a degree of 5%. The computerized evoluation was carried out by means of Spline approximation using the Siemens 4004 computer. Precision and accurateness are in compliance with generally accpted criteria. The serum levels of α and #betta# sub-units showed no discordancy with regard to TSH. In all groups of patients examined, the levels of the hormone-specific #betta#-chain were found to be exclusively dependent upon the actual thyroid activity. (orig.) [de

    The research group has detected nitrosative stress and a singular version of nitrosylated serum α-synuclein in serum of Parkinson's disease (PD) patients. Dysfunction of the thyroid gland has been proposed to be linked to this disease. The aim of the study was to know if the thyroid gland is involved in idiopathic PD and nitrosative stress. We studied 50 patients (early and advanced disease patients), 35 controls, and 6 subjects with thyroidectomy. Clinical characteristics, serum thyroperoxidase levels, and 3-nitrotyrosine proteins were analyzed. Enzyme-linked immunosorbent assay and immunoblotting methods were employed. The findings indicated that the prevalence of two thyroid dysfunctions (hyper- or hypothyroidism) was not found to be different in patients relative to controls. However, the levels of the enzyme thyroperoxidase were found to be elevated in early disease patients (pdisease subjects, and these levels were negatively correlated with serum 3-nitrotyrosine proteins (pthyroid gland and thyroperoxidase participate in nitrosylation of serum proteins and they could influence Parkinsonian nitrosative stress as well as nitrosylation of serum α-synuclein, a potentially pathogenic factor.

    Hashimoto's thyroiditis (HT) and Graves' disease (GD) constitute a spectrum of autoimmune thyroid diseases (AITD). They share an autoimmune pathogenesis, with a cellular and a humoral response to the thyroid gland. As a consequence, dysfunction of the gland itself may develop, characterized by hyperfunction in the case of GD and hypofunction in the case of HT, however at the onset of HT the hyperthyroidism might be observed as a result of a rapid destruction of thyrocytes. An abnormal thyroid echographic pattern characterized by a diffuse low echogeneity has been described in both AITD. This hypoechogeneity is due to three components: increase of intrathyroidal flow, functional changes in thyroid follicles with increased cellularity and decrease of the colloid content, resulting in the reduction of the cell/colloid interface, variable degree of lymphocytic infiltration. The first two components may be reversible during medical treatment and seem to be characteristic for GD, whereas lymphocytic infiltration may rather represent mostly HT. Here we present a 17-year-old girl with typical clinical signs of hyperthyroidism [firm goiter (II degrees), tachycardia, palpitations, nervousness, excessive sweating and tremor]. Laboratory tests were the following: fT3 - 6.59 pg/ml(increasing), fT4 - 1.99 ng/dl(increasing), TSH - 0.02 micro IU/ml(decreasing); anti-Tg-Ab - 840 IU/ml(increasing), anti-TPO-Ab - 190 IU/ml(increasing) (4 months later antithyroid antibodies were 2200 and 70, respectively). Ultrasound examination showed hypoechogeneity of the whole gland and enhanced vascular flow based on power Doppler analysis. Thyroid scan visualized the generally increased uptake of technetium. The girl was put on beta-blocker (propranolol) and later an antithyroid drug (thiamazole) was added. A course of disease was unstable, therefore the fine-needle aspiration biopsy was performed and showed the presence of single groups of normal thyrocytes and scanty colloid with no features

    Full Text Available Abstract Background Three genes have been confirmed as major joint susceptibility genes for endocrine autoimmune disease:human leukocyte antigen class II, cytotoxic T-lymphocyte antigen 4 and protein tyrosine phosphatase non-receptor type 22. Recent studies showed that a genetic variation within the interferon induced helicase domain 1 (IFIH1 locus (rs1990760 polymorphism is an additional risk factor in type 1 diabetes and Graves' disease (GD. Methods The aim of the present study was to investigate the role of the rs1990760 polymorphism within the IFIH1 gene in German patients with GD (n = 258, Hashimoto's thyroiditis (HT, n = 106, Addison's disease (AD, n = 195 and healthy controls (HC, n = 227 as well as in 55 GD families (165 individuals, German and 100 HT families (300 individuals, Italian. Furthermore, the interaction between rs1990760 polymorphism with human leukocyte antigen (HLA risk haplotype DQ2(DQA*0501-DQB*0201, the risk haplotypes DQ2/DQ8 (DQA*0301-DQB*0302 and the status of thyroglobulin antibody (TgAb, thyroid peroxidase antibody (TPOAb and TSH receptor antibody (TRAb in patients and families were analysed. Results No significant differences were found between the allele and genotype frequencies for rs1990760 IFIH1 polymorphism in patients with GD, HT, AD and HC. Also no differences were observed when stratifying the IFIH1 rs1990760 polymorphism for gender, presence or absence of thyroid antibodies (GD:TRAb and HT:TPOAb/TgAb and HLA risk haplotypes (DQ2:for GD and HT, DQ2/DQ8:for AD. Furthermore the transmission analysis in GD and HT families revealed no differences in alleles transmission for rs1990760 IFIH1 from parents with or without HLA risk haplotype DQ2 to the affected offspring. In contrast, by dividing the HT parents according to the presence or absence of thyroid Ab titers, mothers and fathers both positive for TPOAb/TgAb overtransmitted the allele A of IFIH1 rs1990760 to their HT affected offspring (61.8% vs 38.2%;p = 0

    Some patients with hyperthyroid Graves' disease have increased serum T3 and normal or even low serum T4 levels during treatment with antithyroid drugs. These patients with elevated serum T3 to T4 ratios rarely have a remission of their hyperthyroidism. The aim of this study was to investigate thyroid iodine metabolism in such patients, whom we termed T3-predominant Graves' disease. Mean thyroid radioactive iodine uptake was 51.0 +/- 18.1% ( +/- SD) at 3 h, and it decreased to 38.9 +/- 20.1% at 24 h in 31 patients with T3-predominant Graves' disease during treatment. It was 20.0 +/- 11.4% at 3 h and increased to 31.9 +/- 16.0% at 24 h in 17 other patients with hyperthyroid Graves' disease who had normal serum T3 and T4 levels and a normal serum T3 to T4 ratio during treatment (control Graves' disease). The activity of serum TSH receptor antibodies was significantly higher in the patients with T3-predominant Graves' disease than in control Graves' disease patients. From in vitro studies of thyroid tissue obtained at surgery, both thyroglobulin content and iodine content in thyroglobulin were significantly lower in patients with T3-predominant Graves' disease than in the control Graves' disease patients. Thyroid peroxidase (TPO) activity determined by a guaiacol assay was 0.411 +/- 0.212 g.u./mg protein in the T3-predominant Graves' disease patients, significantly higher than that in the control Graves' disease patients. Serum TPO autoantibody levels determined by immunoprecipitation also were greater in T3-predominant Graves' disease patients than in control Graves' disease patients. Binding of this antibody to TPO slightly inhibited the enzyme activity of TPO, but this effect of the antibody was similar in the two groups of patients.

    Objective: To investigate the relationship between serum thyroid hormones levels and severity of heart failure in patients with coronary heart disease (CHD). Methods: Serum thyroid hormones (FT 3 , FT 4 , TSH) levels were measured with RIA in 38 patients with CHD but no cardiac failure, 40 CHD patients with heat failure and 37 controls. Results: The serum FT 3 levels in patients with heart failure were significantly lower than those in the other two groups (P 4 and TSH in all these three groups of subjects. Moreover, the serum FT 3 levels in the patients with heart fail- ure were significantly positively correlated with the ejection fractions (EF) in these patients. Conclusion: Serum FT 3 levels dropped markedly in CHD patients with heart failure and the magnitude of decrease was positively correlated with the severity of the disease. (authors)

    The measurement of free thyroid hormone, instead of the total form, is more commonly used in current practice. We aimed to evaluate the usefulness of the ratio of serum free triiodothyronine (FT3, pg/mL) to free thyroxine (FT4, ng/dL) for differentiating Graves' disease from subacute thyroiditis. Medical records of thyrotoxic patients aged >15 years who had measurement of FT3, FT4 and thyrotropin on the first diagnosis of thyrotoxicosis before initiating treatment were retrospectively reviewed. Data were collected from all clinics, and were not limited to the endocrine clinic. Pregnant women were excluded. A total of 548 patients (468 with Graves' disease, 40 with subacute thyroiditis and 40 with toxic adenoma/multinodular goiter) were recruited. Mean age was 43.9 ± 15.4 years. Most were female 434 (79.2%), and goiter was present in 55.3%. Prevalence of T3-toxicosis and T4-toxicosis were 5.6% and 6.6%, respectively. Mean FT3/FT4 ratios were 4.62 ± 2 (10(-2) pg/ng) in patients with Graves' disease and 2.73 ± 0.5 in subacute thyroiditis. The area under the ROC curve of the FT3/FT4 ratio for diagnosis of Graves' disease was 0.83 (95%CI, 0.76-0.91). Cutoff level of this ratio >4.4 offered sensitivity of 47.2% and specificity of 92.8%. FT3/FT4 ratio of >4.4 (10(-2) pg/ng) may help in differentiating the cause of thyrotoxicosis.

    Autoimmune thyroid diseases (AITDs) are often accompanied by vitiligo, and the sera of patients with vitiligo often demonstrate increased frequencies of thyroid autoantibodies. In this study, we investigated the expression of melanocyte-associated antigens in tissues from patients with Hashimoto's thyroiditis (HT) without vitiligo using immunohistochemistry. Tissues of HT without vitiligo, as well as normal thyroid tissues, were both negative for the expression of NKI/beteb, gp100, tyrosinase-related protein 1 (TRP1), HMB-45 and S100, whereas they were positive for the expression of tyrosinase-related protein 2 (TRP2), lysosome-associated membrane protein 1 (LAMP1) and CD69. Tyrosinase (TYR) was only detected in tissues of HT, and levels of LAMP1 and CD69 were higher in tissues of HT than in normal thyroid tissues (p vitiligo and HT that might represent an immunological basis for secondary HT associated with vitiligo.

    Full Text Available IgG4-related disease is a novel disease entity characterized by diffuse lymphoplasmacytic infiltration rich in IgG4-positive plasma cells and fibrosis into multiple organs. There is still controversy over whether some thyroid diseases are actually IgG4-related disease. The objective of this study was to elucidate the clinicopathological features of Graves' disease with diffuse lymphoplasmacytic infiltration in the thyroid.Among 1,484 Graves' disease patients who underwent thyroidectomy, we examined their histopathological findings including the degree of lymphoplasmacytic and fibrotic infiltration and levels of IgG4-positive plasma cells in the thyroid. Their clinical pictures were defined by laboratory and ultrasonographic evaluation.A total of 11 patients (0.74% showed diffuse lymphoplasmacytic infiltration in the stroma of the thyroid gland. Meanwhile, other patients showed variable lymphoid infiltration ranging from absent to focally dense but no aggregation of plasma cells in the thyroid gland. Based on the diagnostic criteria of IgG4-related disease, 5 of the 11 subjects had specifically increased levels of IgG4-positive plasma cells in the thyroid. Fibrotic infiltration was present in only 1 patient developing hypothyroidism after anti-thyroid drug treatment for 4 years, but not in the other 10 patients with persistent hyperthyroidism. Obliterative phlebitis was not identified in any of the 11 subjects. Thyroid ultrasound examination showed 1 patient developing hypothyroidism who had diffuse hypoechogenicity, but the other hyperthyroid patients had a coarse echo texture.In our study, Graves' disease patients with persistent hyperthyroidism who had diffuse lymphoplasmacytic infiltration rich in IgG4-positive plasma cells in the thyroid showed no concomitant fibrosis or obliterative phlebitis.

    Objective: To investigate complications and causes of thyroid arterial embolization for hyperthyroidism caused by Graves' disease. Methods: Twenty-eight patients with hyperthyroidism caused by Graves' disease had been treated through transcathter arterial embolization with mid-term follow up. The thyroid angiography, interventional treatment, complications and causes were investigated. Results Followed up for over one year (12-24 months), mid-term rate of efficiency was 78.6% with recurrent rate of one year being 14.2%. Two patients (7.1%) had brain infarction with one partially recovered after proper therapy and the other died due to subsequent hyperthyroidism crisis. One case had temporary hypothyroidism, and another hypoparathyroidism but no permanent hypothyroidism or hypoparathyroidism occurred. One patient suffered relatively severe post-embolization syndrome. All the other complications disappeared after proper treatment. Followed up for more than a year, no other complications occurred. Conclusion: Misembolization due to regurgitation of embolized agent is one of the most important factors leading to complications of arterial embolization for Graves' disease. In order to reduce complications and improve therapeutic efficacy, it is essential to superselectively catheterize the thyroid, avoid dangerous anastomose, prevent regurgitation misembolization and strictly operate under fluoroscopy.

  20. The results of the radioiodine-therapy of benign thyroid diseases respecting the applied radiation dose

    452 patients with benign thyroid diseases had been explored after 6 weeks, 6 months, 1 year, 5 years and 10 years after undergone radioiodine treatment retrospectively with regard to the applied radiation dose. A relevant relation between the radiation dose and the rate of hypothyroidism could only be proved as a tendency. Treating hyperthyroidism with radioiodine, the rates of hypothyroidism after therapy were not caused by significantly higher radiation doses. Therefore suggestions to change the used radiation-doses basically cannot be made. The applied doses of radiation are sufficient to achieve a rather satisfactory effect in healing hyperthyroidism. Cases of malignancy after radioiodine therapy could not be found in this population. The effective half-life determination before therapy can be neglected, because there was found a significant difference between the pre-therapeutically estimated half-life and the post-therapeutically measured effective half-life of radioiodine. Instead, fixed values of effective half-life should be used for each group of benign thyroid diseases. The radiation therapy still seems to be an efficient treatment to cure benign thyroid diseases with rare side effects. It also can be applied to patients below the age of 40. Generally it is an alternative to drug-therapy or surgery, always considering the individual relation between gain and risk. In this respect good results can be obtained and a relapse of hyperthyroidism is hardly to expect. (author)

    Full Text Available In previous works we demonstrated an inverse correlation between plasma Coenzyme Q10 (CoQ10 and thyroid hormones; in fact, CoQ10 levels in hyperthyroid patients were found among the lowest detected in human diseases. On the contrary, CoQ10 is elevated in hypothyroid subjects, also in subclinical conditions, suggesting the usefulness of this index in assessing metabolic status in thyroid disorders. A Low-T3 syndrome is a condition observed in several chronic diseases: it is considered an adaptation mechanism, where there is a reduction in pro-hormone T4 conversion. Low T3-Syndrome is not usually considered to be corrected with replacement therapy. We review the role of thyroid hormones in regulation of antioxidant systems, also presenting data on total antioxidant capacity and Coenzyme Q10. Published studies suggest that oxidative stress could be involved in the clinical course of different heart diseases; our data could support the rationale of replacement therapy in low-T3 conditions.

    Substantial reductions in thyroid volume (up to 70-80%) after radioiodine therapy of Graves' hyperthyroidism are common and have been reported in the literature. A relationship between thyroid volume reduction and outcome of 131I therapy of Graves' disease has been reported by some authors. This important result could be used to decide individually the optimal radioiodine activity A0 (MBq) to administer to the patient, but a predictive model relating the change in gland volume to A0 is required. Recently, a mathematical model of thyroid mass reduction during the clearance phase (30-35 days) after 131I administration to patients with Graves' disease has been published and used as the basis for prescribing the therapeutic thyroid absorbed dose. It is well known that the thyroid volume reduction goes on until 1 year after therapy. In this paper, a mathematical model to predict the final mass of Graves' diseased thyroids submitted to 131I therapy is presented. This model represents a tentative explanation of what occurs macroscopically after the end of the clearance phase of radioiodine in the gland (the so-called second-order effects). It is shown that the final thyroid mass depends on its basal mass, on the radiation dose absorbed by the gland and on a constant value α typical of thyroid tissue. α has been evaluated based on a set of measurements made in 15 reference patients affected by Graves' disease and submitted to 131I therapy. A predictive equation for the calculation of the final mass of thyroid is presented. It is based on macroscopic parameters measurable after a diagnostic 131I capsule administration (0.37-1.85 MBq), before giving the therapy. The final mass calculated using this equation is compared to the final mass of thyroid measured 1 year after therapy administration in 22 Graves' diseased patients. The final masses calculated and measured 1 year after therapy are in fairly good agreement (R = 0.81). The possibility, for the physician, to decide a

    To report an unusual case of IgG4-related Mikulicz's disease associated with thyroiditis. We describe a 25-year-old Chinese man who presented with bilateral, painless swellings of the lachrymal glands, parotid glands, and thyroid nodules. The patient underwent left-sided dacryoadenectomy and the diagnosis of IgG4-related Mikulicz's disease was pathologically confirmed. The size of the right-sided lachrymal gland and parotid glands recovered fundamentally after one month of glucocorticoid therapy. IgG4-related Mikulicz's disease associated with thyroiditis should be considered in the differential diagnosis of bilateral swellings of lachrymal glands, salivary glands, and thyroid nodules. Surgical excision is recommended in order to treat the tumor and to ensure the pathological diagnosis. Glucocorticoid therapy should be considered in association with surgery after removal.

    Full Text Available Abstract Background Both thyroid stimulating hormone (TSH and thyroid stimulating antibody (TSAb negative Graves’s disease (GD is extremely rare. Here we present such a patient. Case presentation The patient was a 76-year-old woman who was diagnosed as having schizophrenia forty years ago. She did not show characteristic symptoms for hyperthyroidism, such as swelling of thyroid, exophthalmos, tachycardia and tremor, however, she showed only psychomotor agitation. Serum free triiodothyronine and free thyroxine levels were elevated and TSH level was suppressed, suggesting the existence of hyperthyroidism. However, both the first generation TSH receptor autoantibody (TRAb1 and the thyroid stimulating autoantibody (TSAb were negative. Slightly increased blood flow and swelling was detected by thyroid echography. Thyroid scintigraphy demonstrated diffuse and remarkably elevated uptake of 123I uptake. Finally, we diagnosed her as having GD. She was treated by using methimazole, and hyperthyroidism and her psychiatric symptoms were promptly ameliorated. Discussion We experienced a patient with GD who did not show characteristic symptoms except for psychiatric symptoms, and also showed negativity for both TRAb1 and TSAb. Thyroid autoantibody-negative GD is extremely rare. Thyroid scintigraphy was useful to diagnose such a patient.

    Riedel's thyroiditis (RT) is a rare chronic fibrosing disorder characterized by a hard, infiltrative lesion in the thyroid gland, which is often associated with multifocal fibrosclerosis. Immunoglobulin G4-related disease (IgG4-RD) is typified by infiltration of IgG4-positive plasma cells into multiple organs, resulting in tissue fibrosis and organ dysfunction. In order to evaluate the clinicopathological features of RT and its relationship with IgG4-RD, we performed a Japanese literature search using the keywords "Riedel" and "Riedel's thyroiditis." We used the electronic databases Medline and Igaku Chuo Zasshi, the latter of which is the largest medical literature database in Japan. The diagnosis of RT was based on the presence of a fibroinflammatory process with extension into surrounding tissues. Only 10 patients in Japan fulfilled RT diagnostic criteria during the 25-year period between 1988 and 2012. Two patients with confirmed IgG4/IgG immunohistochemical findings demonstrated 43 and 13 IgG4-positive plasma cells per high-power field, respectively, and the IgG4-positive/IgG-positive plasma cell ratios of 20% and less than 5%. Of the 10 patients with RT, two received glucocorticoids, one of whom experienced marked shrinkage of the thyroid lesion. One patient had extra-thyroid involvement in the form of retroperitoneal fibrosis. Although the clinicopathological features of RT suggest that IgG4-RD may be the underlying condition in some cases, further investigation is needed to clarify the etiology of RT in relation to IgG4-RD.

    Viral infections frequently have been cited as important environmental factors implicated in the onset of autoimmune thyroiditis (AIT). The aim of this study was to determine the involvement of HHV-6 infection in the development of autoimmune thyroiditis. This study included 45 patients (42 female and 3 male; median age 47.00 IQR 38.50-57.00) with histologically, laboratory, and clinically confirmed autoimmune thyroiditis, as well as 30 autopsied subjects (26 female and 4 male; median age 58.50, IQR 51.50-67.00) without thyroid pathologies and 30 healthy blood donors (25 female and 5 male; median age 33.50, IQR 27.75-44.25) as controls. Results were obtained by applying molecular virology and immunohistochemistry techniques. The presence of persistent HHV-6 infection in AIT patients was significantly higher (p 0.0058) than in the control group (44/45 (98%) vs. 23/30 (77%), respectively). Also, a significantly higher frequency of HHV-6 activation marker (U79/80 mRNA) was found in patients' thyroid gland tissue samples with AIT in comparison with the control group (18/44 (41%) vs. 1/17 (6%), respectively; p 0.0118). The median HHV-6 load was found to be higher in patients with active viral infection than in patients without it (2147, IQR 971-4188 vs. 551, IQR 145-1589 copies/1×10 6 cells; p 0.003). The presence of HHV-6 antigen expression was demonstrated in intrafollicular cellular clusters and immunohistochemistry indicated thyrocytes in the follicle wall. These findings provide evidence of strong HHV-6 infection association with AIT development. Copyright © 2016 European Society of Clinical Microbiology and Infectious Diseases.

    Radioiodine therapy is a reliable and cost-effective alternative to medical treatment of Graves' hyperthyroidism. Current recommendations favour a risk-adapted therapeutic procedure. Medical treatment is preferred in patients with a low risk of relapse which are characterised by the combination of female gender, age of onset above 40 years, thyroid volume below 40 ml and TSH-receptor antibodies below 10 U/l. Because of the poor remission rate with medical treatment in patients at less than 40 years of age, male gender, thyroid volume above 40 ml and TSH receptor antibodies above 10 U/l, it is suggested that definitive treatment with radioiodine or surgery should be considered soon after disease presentation. Analysis of cost-effectiveness clearly favour ablative radioiodine treatment. Ablative treatment is even more favourable in terms of early resumption of a normal life style of the hyperthyroid patient. Recent publications suggest further an adaptation of the tissue-absorbed dose to the pre-treatment thyroid volume using Marinelli's formula to achieve thyroid ablation with a single radioiodine treatment.

    Denmark was an area of iodine deficiency, and mandatory iodine fortification of table salt and salt in bread (13 p.p.m. iodine) was initiated in 2000/2001. The Danish investigation on iodine intake and thyroid disease (DanThyr) is the monitoring of the iodine fortification program. DanThyr consists of three main parts: a study of population cohorts initialized before (n=4649) and after (n=3570) iodization of salt, a prospective identification of incident cases of overt hyper- and hypothyroidism in a population of around 550,000 people since 1997, and compilation of data from the national registers on the use of thyroid medication, thyroid surgery, and radioiodine therapy. Studies were carried-out in parallel in subcohorts living in areas with differences in iodine content of ground water. The study showed profound effects of even small differences in iodine intake level on the prevalence of goiter, nodules, and thyroid dysfunction. Mild and moderate iodine deficiency was associated with a decrease in serum TSH with age. Other environmental factors were also important for goiter development (increase in risk, smoking and pregnancy; decrease in risk, oral contraception and alcohol consumption), and the individual risk depended on the genetic background. Environmental factors had only a minor influence on the prevalence of thyroid autoantibodies in the population. There were more cases of overt hypothyroidism in mild than in moderate iodine deficiency caused by a 53% higher incidence of spontaneous (presumably autoimmune) hypothyroidism. On the other hand, there were 49% more cases of overt hyperthyroidism in the area with moderate iodine deficiency. The cautious iodine fortification program, aiming at an average increase in iodine intake of 50 mug/day has been associated with a 50% increase in incidence of hyperthyroidism in the area with the most severe iodine deficiency. The incidence is expected to decrease in the future, but there may be more cases of Graves

    Background/Aims To characterize ultrasonographic findings in papillary thyroid carcinoma (PTC) combined with Graves' disease. Methods Medical records and ultrasonographic findings of 1,013 patients with Graves' disease and 3,380 patients without Graves' disease were analyzed retrospectively. A diagnosis of PTC was based on a pathologic examination. Results The frequency of hypoechogenicity was lower in patients with PTC and Graves' disease than in patients with PTC alone (p Graves' disease was significantly higher than in those with PTC alone (p Graves' disease was characterized by more ill-defined borders and less frequency of overall calcification, punctate calcification, and heterogeneous echogenicity, although the difference was not statistically significant. Conclusions Our results suggest that patients with Graves' disease more frequently have atypical PTC findings on ultrasonography. PMID:20195406

    Overt and subclinical hypothyroidism are associated with higher levels of serum creatinine and with increased risk of chronic kidney disease (CKD). The prospective association between thyroid hormones and kidney function in euthyroid individuals,however, is largely unexplored. We conducted a prospective cohort study in 104 633 South Korean men and women who were free of CKD and proteinuria at baseline and had normal thyroid hormone levels and no history of thyroid disease or cancer. At each annual or biennial follow-up visit, thyroid-stimulating hormone (TSH), free triiodothyronine (FT3) and free thyroxin (FT4) levels were measured by radioimmunoassay. The study outcome was incident CKD, defined as an estimated glomerular filtration rate (eGFR)<60 ml/min/1.73 m2 based on the Chronic Kidney Disease Epidemiology Collaboration creatinine equation. After a median follow-up of 3.5 years, 1032 participants developed incident CKD.There was a positive association between high-normal levels of TSH and increased risk of incident CKD. In fully-adjusted models including baseline eGFR, the hazard ratio comparing the highest vs the lowest quintiles of TSH was 1.26 [95% confidence interval (CI) 1.02 to 1.55; P for linear trend=0.03]. In spline models, FT3 levels below 3 pg/ml were also associated with increased risk of incident CKD. There was no association between FT4 levels and CKD. In a large cohort of euthyroid men and women, high levels of TSH and low levels of FT3, even within the normal range, were modestly associated with an increased risk of incident CKD.

    Hashimoto thyroiditis (HT) and the fibrosing variant of Hashimoto thyroiditis (FVHT) are immune-mediated tumefactive lesions of the thyroid. Immunoglobulin G4-related disease (IgG4-RD) is now a widely recognised multi-organ system disease characterised by elevated serum and tissue concentrations of IgG4. In this study, the authors address several unresolved questions pertaining to the relationship between HT and FVHT, and the association of each of these diseases with IgG4-RD. The authors evaluated 28 consecutive cases of HT and nine cases of FVHT. The clinical, demographic and serological data were recorded. The slides were stained immunohistochemically using antibodies to IgG4 and IgG and the quantitative analysis was recorded. Data on thyroid function tests were available on seven cases of FVHT and 14 cases of HT. Based on the availability of data, hypothyroidism was noted in 62% (9/14) of HT and 86% of FVHT (6/7). FVHT demonstrated an exaggerated lobular pattern with lobules separated by cellular storiform-type fibrosis, resembling fibrosis seen in other forms of IgG-RD. The median IgG4 counts per high power field (×40) in HT and FVHT were 2.3 and 22, respectively. The median IgG4:IgG ratios in HT and FVHT were 0.11 and 0.58, respectively. The authors propose that FVHT belongs to the spectrum of IgG4-RD. Although a proportion of cases of HT show elevated numbers of IgG4 positive plasma cells, these cases lack the histological features typically associated with IgG4-RD, and thus the relationship between HT and IgG4-RD remains unproven.

    Riedel thyroiditis is a benign disease, which is often self-limited. Examinations, such as CT and histologic diagnosis can distinguish it from malignant neoplasms and hashimoto's thyroiditis. Riedel thyroiditis is an uncommon form of chronic thyroiditis in which the thyroid gland is replaced by fibrous tissue. It can be cured by surgery and medicine.

    Obesity and thyroid diseases are common disorders in the general population and they frequently occur in single individuals. Alongside a chance association, a direct relationship between 'thyroid and obesity' has been hypothesized. Thyroid hormone is an important determinant of energy expenditure and contributes to appetite regulation, while hormones and cytokines from the adipose tissue act on the CNS to inform on the quantity of energy stores. A continuous interaction between the thyroid hormone and regulatory mechanisms localized in adipose tissue and brain is important for human body weight control and maintenance of optimal energy balance. Whether obesity has a pathogenic role in thyroid disease remains largely a matter of investigation. This review highlights the complexity in the identification of thyroid hormone deficiency in obese patients. Regardless of the importance of treating subclinical and overt hypothyroidism, at present there is no evidence to recommend pharmacological correction of the isolated hyperthyrotropinemia often encountered in obese patients. While thyroid hormones are not indicated as anti-obesity drugs, preclinical studies suggest that thyromimetic drugs, by targeting selected receptors, might be useful in the treatment of obesity and dyslipidemia. © 2014 European Society of Endocrinology.

    The aim of this study was to evaluate proteins oxidation in plasmas of two autoimmune thyroid diseases (AITD): Graves' disease (GD) and Hashimoto Thyroiditis (HT), and to determine whether oxidative modification of thyroid antigens (T.Ag) enhanced the reactivity of autoantibodies in plasmas of AITD patients compared with the reactivity towards native T.Ag. Carbonyl and thiol groups and MDA-protein adducts were assessed spectrophotometric methods in plasmas of 74 AITD patients and 65 healthy controls. The reactivities immunoglobulin (Ig)G autoantibodies towards malondialdéhyde (MDA)-modified T.Ag, hydrogen peroxide (H 2 O 2 )-modified T.Ag, native T.Ag and native derm were checked by enzyme-linked immunosorbent assay (ELISA). Evaluation of oxidized proteins exhibited high levels of MDA bound to proteins and carbonyl groups, as well as reduced thiol level in plasmas of AITD patients by comparison to healthy controls (p thyroid stimulating hormone level in HT patients in the other (r = 0.65, p < 0.001). The data suggest that high production of H 2 O 2 probably occurred during hormone synthesis could contribute to protein oxidation in AITD and to create neoepitopes responsible for autoantibody reactivity's to H 2 O 2 -oxidized T.Ag enhancement. These results provide support to the involvement of oxidative stress in AITD development and/or exacerbation. Copyright © 2017 Elsevier B.V. All rights reserved.

    The prevalence of thyroid nodules and thyroid cancer was studied in the indigenous population residing on Ebeye Island, Kwajalein Atoll, in the Republic of the Marshall Islands. This island, centrally located in the nation, is home to about 25% of the nation's population, many who have migrated there from other atolls. The objective of the study was to obtain thyroid disease rate statistics on as much of the population as possible that was alive during the years of nuclear testing and to test the hypothesis that described a linearly decreasing prevalence of palpable nodules with increasing distance from the Bikini test site. 1,322 Marshallese born before 1965 were given a thyroid examination using neck palpation, fine needle aspiration biopsy, and high resolution ultrasound imaging. Approximately 40% of the total population living on this island who are at risk from exposure to radioactive fallout during the years 1946-1958 were screened. Of that group, 815 were alive at the time of the BRAVO test on 1 March 1954. Two hundred sixty-six people with thyroid nodules were found (32.6%): 132 were palpable nodules (16.2%), and 134 were nodules that could be diagnosed with ultrasound only (15.7%). Prevalence of palpable nodules was particularly high in men and women older than 60 y, in men who were 6 to 15 y of age at the time of the BRAVO test, and in women 1 to 10 y of age at the time of the BRAVO test. In 22 people, the clinical diagnosis was most likely cancer though histopathological evidence was only available from 11 operated cases. Of the 11 operated cases, 10 were cancer. Cancer prevalence was particularly high in those women born between 1944 and 1953 (7/220 = 3.2%), i.e., who were children during the early years of nuclear testing. The Ebeye data showed a marginally significant correlation between palpable nodule prevalence among women and distance to Bikini (r = -0.44, p = 0.06).

    Full Text Available As there are no previous studies on the interleukin-22 (IL-22 variants in autoimmune thyroid disease (AITD, the present study aimed to explore the association between polymorphisms of IL-22 and the predisposition to AITD. The study had 975 AITD patients, including 639 Graves’ disease (GD and 336 Hashimoto’s thyroiditis (HT individuals and 851 healthy cohorts. Ligase detection reaction (LDR and direct sequencing method were used for genotyping the IL-22 gene polymorphisms at rs2046068, rs2227478, rs2227485, rs11611206, and rs1179251. In comparison to female controls, genotype CC of rs1179251 was increased in the female AITD patients. Alleles C at rs2046068, C at rs2227478, and C at rs1179251 linked to the susceptibility of HT males. Genotype CC in rs1179251 was higher in male HT. Variants at rs2046068, rs2227478, and rs1179251 were associated with the AITD teenagers. Besides, genotype GG in rs11611206 was correlated with thyroid-associated ophthalmopathy (TAO. Moreover, allele G at rs11611206 was associated with decreased risk for TAO by 28.9%. Similarly, genotype CC of rs1179251 and genotype GG of rs11611206 were associated with Graves’ ophthalmopathy (GO. Allele G in rs11611206 increased people with HT towards the predisposition of hypothyroidism. In conclusion, genetic variants of IL-22 are associated with the occurrence of AITD.

EM prevalence in TD patients was higher compared to the general population (Odds Ratio, OR 3.21 and the most frequent EM was breast cancer (OR 3.94, followed by colorectal (OR 2.18, melanoma (OR 6.71, hematological (OR 8.57, uterus (OR 2.52, kidney (OR 3.40 and ovary (OR 2.62 neoplasms. Age-matched analysis demonstrated that the risk of EM was maximal at age 0-44 yr (OR 11.28, remaining lower, but significantly higher that in the general population, in the 45-59 and 60-74 year age range. Breast and hematological malignancies showed an increased OR in all TD, while other cancers associated with specific TD. An increased OR for melanoma, breast and hematological malignancies was observed in both TPOAb and/or TgAb autoantibody negative and positive patients, while colorectal, uterus, kidney and ovary cancers showed an increased OR only in thyroid autoantibody negative patients. In conclusions, women affected by both benign and malignant TD, especially at a younger age and in absence of thyroid autoimmunity, have an increased risk of developing primary EM, thus requiring a careful follow-up and surveillance.

    Recent studies have identified common genetic variants associated with TSH, free T4 and thyroid peroxidase antibodies, but it is unclear whether these differ between patients with Hashimoto's disease and Graves' disease. To examine whether 11 common genetic variants differ between Graves' disease and Hashimoto's disease. We genotyped 11 common variants in a discovery cohort of 203 Australian patients with autoimmune thyroid disease (AITD). Two variants with significant or suggestive associations were analysed in a replication cohort of 384 Danish patients. For rs753760 (PDE10A), the minor allele frequency in Graves' disease and Hashimoto's disease was 0·38 vs. 0·23, respectively, (P = 6·42 × 10 -4 ) in the discovery cohort, 0·29 vs. 0·24 (P = 0·147) in the replication cohort and 0·32 vs. 0·24 in combined analysis (P = 0·0021; all analyses adjusted for sex). In healthy controls from Busselton, the frequency was 0·29, significantly different from Hashimoto's disease but not Graves' disease. For rs4889009 (MAF gene region), the frequency of the minor G-allele in Graves' disease and Hashimoto's disease was 0·48 vs. 0·36 (P = 0·0156) in the discovery cohort, 0·48 vs. 0·34 (P = 1·83 × 10 -4 ) in the replication cohort and 0·48 vs. 0·35 in the combined analysis (P = 7·53 × 10 -6 ); in controls, the frequency was 0·38, significantly different from Graves' disease but not Hashimoto's disease. After further adjustment for smoking, associations with rs4889009 remained significant, whereas those with rs753760 were not. Common variants in PDE10A and MAF gene regions may influence whether patients with AITD develop Graves' disease or Hashimoto's disease. © 2015 John Wiley & Sons Ltd.

    Female residents of 13 counties of Western Washington, in whom papillary, follicular, or mixed papillary-follicular thyroid carcinomas had been diagnosed between 1974 and 1979 were interviewed regarding their medical and reproductive histories and past exposure to radiation treatments. For comparison, a random sa
