    The aim of this study was to compare ultrasonographic features in patients with lymphocytic thyroiditis (LT) and papillary thyroid carcinoma (PTC) having suspicious thyroid nodule(s) in a background of heterogeneous parenchyma and to determine the clinical and radiological predictors of malignancy. We reviewed the cases of 100 patients who underwent ultrasonography between April 2011 and October 2012, and showed suspicious thyroid nodule(s) in a background of heterogeneous parenchyma. Eight patients who did not undergo ultrasonography-guided fineneedle aspiration cytology (FNAC) and 34 cases of follow-up ultrasonography after initial FNAC were excluded. We compared the benign and malignant nodules in terms of their clinical and radiological factors. For the 58 nodules including 31 LTs (53.4%) and 27 PTCs (46.6%), the mean tumor sizes of the two groups were 0.96 cm for LT and 0.97 cm for PTC. A univariate analysis revealed that PTCs were more frequent in patients younger than 45 years and having microcalcifications than was LT. An independent predictor of PTC after adjustment was an age of <45 years. LT mimics malignancy in a background of heterogeneous parenchyma on ultrasonography. A young age of <45 years is the most important predictor of malignancy in this condition.

    An association between lymphocytic thyroiditis and thyroid papillary carcinoma is still controversial. To assess the relationship, a histopathologic analysis of surgically resected thyroid tumors together with the frequency and severity of chronic lymphocytic infiltration of the thyroid among patients with follicular adenoma, follicular carcinoma, and papillary carcinoma was performed. The prevalence of lymphocytic infiltrate, which is indicative of autoimmune thyroiditis, was significantly higher in patients with papillary carcinoma (58%) than in patients with follicular carcinoma (20%) or follicular adenoma (14%). The lymphocytic infiltration within the tumor compared with the severity of thyroiditis in the nontumorous tissue. Therefore, the association between chronic lymphocytic thyroiditis and papillary carcinoma was confirmed. The possibility that an immunologic mechanism involved in the pathogenesis of papillary carcinoma stimulates lymphocytic infiltration in the thyroid tissue through an autoimmune mechanism is suggested.

    A forensic autopsy study comprising 125 cases was carried out retrospectively in order to evaluate pathological changes in the thyroid gland in different groups of death. The five groups selected consecutively were: (i) opiate addicts who died from an overdose, (ii) alcoholics who died as a result of their alcohol abuse, (iii) cases of fatal poisoning other than opiate addicts, (iv) unknown cause of death and (v) controls without prior disease. Tissue samples from the thyroid gland were cut and stained with haematoxylin and eosin and van Gieson. Histology examinations were subsequently performed blind with semiquantitative assessment of the following six parameters: (a) height of the follicular epithelium, (b) the amount of lymphocytes, (c) the presence of plasma cells, (d) hyperplastic follicular changes, (e) oxyphilic changes, and (f) fibrosis. The most striking result was the finding of extensive lymphocytic infiltration of the thyroid parenchyma in five of the 124 cases, of which four belonged in the group of 'unknown cause of death'. This discovery leads to reflections regarding lymphocytic thyroiditis as a cause of death, either by itself or in combination with other disorders. Silent (painless) thyroiditis, especially, is easily overlooked at autopsy as there are no macroscopic changes and often no prior symptoms or history of thyroid disease pointing towards this condition. Analyses of thyroid hormones are unreliable in predicting endocrine status in life. Routine microscopy of the thyroid gland is therefore advocated in cases of sudden unexpected death in order to diagnose thyroid disease, in particular silent (painless) thyroiditis.

    Background. Chronic lymphocytic thyroiditis is the second most common thyroid lesion diagnosed on FNAC after goiter. FNAC is reliable tool in the diagnosis of thyroid lesion. Objective. To correlate FNAC cytologic findings with TFT in the lymphocytic thyroiditis. Methods. 175 patients with thyroid swellings were referred for FNAC as well as TFT during 2011-2013. Fine needle aspiration cytology was performed using non-aspiration or aspiration techniques and TFT performed on Beckman culter access 2. Results. Lymphoid infiltrate was seen in 55 cases. The commonest age group of lymphocytic thyroiditis was 21-30 years with male : female ratio being 1 : 10. Anti-TPO and TSH were elevated in 96.16% (25/26) of cases with grade 3 lymphoid infiltrate, 94.12% (16/17) of cases with grade 2, and 91.67% (11/12) of cases with 1 grade. Increased anti-TPO with raised TSH without any lymphoid infiltrate was seen in 5 cases and 5 cases showed only raised TSH without raised anti-TPO and without any lymphoid infiltrate. We observed that grade 3 lymphocytic infiltration has correlation with anti-TPO and TSH together or TSH alone but not with anti-TPO alone. We also observed that anti-TPO and TSH together are significant even if no lymphocytic infiltration is present. Conclusion. Grade 3 lymphocytic infiltration has statistical correlation with anti-TPO and TSH together or TSH alone but not with anti-TPO alone. Anti TPO was adjunct to TSH in grade 3. The presence of Hurthle cell change, giant cells, and granulomas has no statistical correlation with lymphocytic thyroiditis.

    Patients undergoing thyroidectomies at Evanston (I11) Hospital, during a six-month period had immunological studies performed preoperatively. No differential could be found between those with carcinoma or benign pathologic findings. T- and B-cell distribution and lymphocytic response to mitogens varied widely. Quantitative immunoglobulins showed slightly increased levels of IgG in patients wih carcinoma and thyroiditis in comparison with those patients with adenomas. Antithyroglobulin antibodies were negative in all patients. Pathology slides from 107 patients with thyroid carcinoma between 1972 and 1978 at Evanston Hospital were reviewed for the presence of thyroiditis, either focal or diffuse. It was found that 50% of all carcinomas had either diffuse or focal thyroiditis. Diffuse thyroiditis was more common in patients with no history of irradiation and papillary carcinoma, and in younger age groups.

    The histologic diagnosis of lymphocytic (Hashimoto) thyroiditis requires lymphocytic inflammation of the thyroid gland in combination with Hourthle cell metaplasia of follicular epithelial cells. Clinically, this autoimmune process has been associated with hypothyroidism and psychiatric conditions including depression. This retrospective study was designed to quantify the incidence and severity of lymphocytic thyroiditis in a series of nonconsecutive suicides compared with a cohort of motor vehicle accident victim controls. Eighty-one suicide victims (61 male, 20 female; age range 13-79 years, average 43) were compared with 88 age and gender matched controls (64 males, 24 females; age range 19-85 years, average 36). The degree of lymphocytic inflammation of the thyroid gland was graded on a scale of 0 to 3 (0 = no inflammation, 1 = mild inflammation, 2-3 moderate-to-marked inflammation with Hourthle cell metaplasia). Slides from each case were reviewed while blinded to the cause and manner of death in each case. Of these 169 total cases, 8 (4.7%) received a score of 3, whereas additional 7 (4.1%) received a grade of 2. Eighty-six percent of all of the cases showed no significant inflammation and recorded a score of 0. Of the 81 suicides, 3 had a score of 3, and 3 had a score of 2 (combined incidence of 7.4%). Within the control group, 5 of 88 cases scored 3 and another 4 scored 2 (combined incidence = 10.2%). Three males and 5 females scored 3 with an age range of 23 to 63 years, average 42. Incidental data tabulated showed that 19% of suicide victims were on psychoactive medications compared with 6% in the motor vehicle accident control group. No one on this study was on thyroid hormone replacement therapy. Depression is strongly linked to suicide and lymphocytic thyroiditis may be a cause of depression. Based on this study, however, the presence of lymphocytic thyroiditis cannot be used as a histologic adjunct to discriminate between suicide and accident in

    Full Text Available Abstract Introduction Subacute lymphocytic thyroiditis is anautoimmune thyroid disease presenting with transient thyrotoxicosis as well as transient hypothyroidism. Several factors have been thought to be the initiating event in subacute lymphocytic thyroiditis. However, subacute lymphocytic thyroiditis that develops after thyroid lobectomy has not yet been reported in the literature. We report a case of subacute lymphocytic thyroiditis after lobectomy in a patient with papillary thyroid carcinoma. Case presentation A 30-year-old Korean woman was referred to our center for thyroid tumor operation. She was diagnosed with suspicious papillary thyroid carcinoma by fine needle aspiration at a local medical clinic. The thyroid ultrasonography demonstrated a diffusely enlarged thyroid gland with a 0.4×0.3cm sized hypoechoic nodule in the left lobe. Left thyroid lobectomy by endoscopic thyroidectomy was performed via a transaxillary approach, and the nodule was confirmed to be a papillary thyroid carcinoma. On postoperative day 1, a thyroid function test revealed hyperthyroidism, and on postoperative day 8, a thyroid function test again revealed hyperthyroidism with decreased radioactive iodine uptake. Thyroid function tests showed euthyroid on postoperative day 48 and hypothyroidism on postoperative day 86. She was treated with levothyroxine. Conclusion Subacute lymphocytic thyroiditis can develop after thyroid lobectomy. Thyroid autoantigen released during thyroid lobectomy may cause the onset or exacerbation of the destructive process.

    Thyroid cancers are usually surrounded by a significant number of immune-reactive cells. Tumor-associated lymphocytes as well as background lymphocytic thyroiditis are frequently mentioned in pathology reports of patients who have undergone surgery for thyroid cancer. The nature of this lymphocytic reaction is not well understood. The fact that cancer can survive in this adverse microenvironment is indicative of immune regulation. We characterized the lymphocytic infiltration that accompanies thyroid cancer and compared it with that present in thyroid autoimmunity. We found that double-negative (DN) T cells were significantly more abundant in thyroid cancer than in thyroid autoimmunity. Although FOXP3(+) regulatory T cells were also present, DN T cells were the dominant cell type, associated with thyroid cancer. Furthermore, upon stimulation, the DN T cells associated with cancer remained unchanged, while the few (20%). CD25 expression on DN T cells remained unchanged after stimulation, which indicates that the increase in the absolute number of DN T cells in thyroid autoimmunity was at the expense of inactivation of single-positive T cells. We concluded that in the setting of thyroid cancer, DN T cells appear to suppress tumor immunity. In contrast, in thyroid autoimmunity, DN T cells were barely present and only increased at the expense of inactivated, single-positive T cells upon induction. Together, these findings indicate that thyroid cancer-associated DN T cells might regulate proliferation and effector function of T cells and thereby contribute to tumor tolerance and active avoidance of tumor immunity.

    Full Text Available In recent years, some reports have suggested that papillary thyroid cancers are more frequently associated with lymphocytic thyroiditis or Hashimoto's thyroiditis. This study investigated a potential increase in the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients.We used national epidemiological survey data on thyroid cancer patients diagnosed in 1999, 2005, and 2008. A retrospective medical record survey was conducted by representative sampling of a national cancer incidence database. The analysis included 5,378 papillary thyroid cancer patients aged 20-79 years. We calculated the age-standardized prevalence and age-adjusted prevalence ratios using a binomial regression model with a log link for the prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients by sex for each year.The prevalence of chronic lymphocytic thyroiditis among papillary thyroid cancer patients was 4.0% and 12.8% for men and women in 1999, 6.5% and 24.6% in 2005, and 10.7% and 27.6% in 2008, respectively. Between 1999 and 2008, the age-standardized prevalence of chronic lymphocytic thyroiditis increased 4.1-fold in male patients and 2.0-fold in female patients with papillary thyroid cancer. The prevalence of other thyroid diseases, however, did not increase in either gender.Among Korean papillary thyroid cancer patients, the prevalence of chronic lymphocytic thyroiditis increased between 1999 and 2008, whereas the prevalence of other thyroid disorders did not change.

    Full Text Available Background: Hashimoto’s thyroiditis sometimes referred to as goitrous thyroiditis is a synonym of chronic lymphocytic thyroiditis or autoimmune thyroiditis. Chronic lymphocytic thyroiditis (Hashimoto’s thyroiditis is one of the most common cause of goiter and hypothyroidism, it is found most commonly in middle aged and young female, but can also occur in other age groups, including children. Chronic lymphocytic thyroiditis can be graded based on cytomorphology. In this study an attempt has been made to correlate the grades with clinical findings, biochemical levels and ultrasonography findings. Methods: This is a prospective study conducted on 309 patients in the Department of Pathology, Andhra Medical College, Visakhapatnam. The various parameters like patient’s clinical presentation, biochemical levels and thyroid ultrasound were studied. Fine needle aspiration of thyroid gland and grading of thyroiditis was done on smears. The grades were correlated with above parameters and the correlation indices were evaluated statistically. Chi-square tests were used for statistical correlation and p value of <0.05 was considered significant. Results: Most of the patients were females (297, 96.11% who commonly presented with a diffuse goiter (263, 85.11%. Asymptomatic cases (193, 62.46% and elevated TSH (194, 62.78% were common. Most of the cases had grade I/II disease (299, 96.76% by cytology. Conclusion: FNAC is a simple, safe and cost effective procedure and is a sensitive and specific diagnostic tool in diagnosing chronic lymphocytic thyroiditis. Cytological grading of chronic lymphocytic thyroiditis helps in assessing the severity of the disease and can predict the thyroid functional status. A combined approach of cytological grading of chronic lymphocytic thyroiditis along with ultrasonography and biochemical levels can detect subclinical hypothyroid states and provide a guide to therapy.

    Primary Lymphoma of the thyroid is one of the very rare entities accounting to less than 2% of thyroid malignancies. We present a case of primary Non-Hodgkin’s Lymphoma of the thyroid with lymphocytic thyroiditis in a 60 year old woman. The patient presented with a rapidly growing nodular mass in the thyroid. The histological and immune marker features of the tumour were consistent with Primary Non-Hodgkin’s Lymphoma of the thyroid with associated thyroiditis.

    Chronic lymphocytic thyroiditis characterized by multifocal follicular lymphoid cell infiltrates with germinal centers, thyroid acinar atrophy and pituitary cell hyperplasia/hypertrophy of the adenohypophysis was detected in a vehicle control, 4-year-old female Cynomolgus macaque in a routine toxicology study. Lymphoid cells of germinal centers were positive for the B-cell marker CD20 by immunohistochemistry (IHC), while remaining lymphocytes were positive for the T-cell marker CD3. Hypertrophied/hyperplastic pituitary cells were positive for thyroid stimulating hormone (TSH) by IHC, consistent with an adaptive response due to removal of hormonal negative feedback from the diseased thyroid gland. Features of this case are similar to chronic lymphocytic thyroiditis in humans, an autoimmune disorder also known as Hashimoto's disease. Chronic lymphocytic thyroiditis with compensatory pituitary changes may occur spontaneously in young, clinically normal cynomolgus macaques and its presence in drug treated animals should be interpreted with caution.

    Lymphocytic adrenal medullitis characterized by inflammation and atrophy in the medulla of the bilateral adrenal glands was observed in an 18-month-old male laboratory beagle dog. It might be that the present lymphocytic adrenal medullitis is an autoimmune-mediated disease as the histological characteristics are consistent with an autoimmune pathogenesis. However, the actual cause remains unclear as the existence of serum autoantibodies against the adrenal medulla could not be confirmed. Although this dog also contracted lymphocytic thyroiditis along with serum thyroglobulin autoantibodies, indicating that the thyroiditis occurred with an autoimmune basis; the relation between the adrenal medullitis and thyroiditis is unknown.

    Thyroid lymphomas are rare clinical entities that may result from either the primary intrathyroid de novo or secondary thyroid gland involvement of a lymphoma. Among these, the Hodgkin's subtype is quite uncommon, accounting for 0.6–5% of all thyroid malignancies. The authors report on a 76-year-old female presenting with a thyroid nodule that, upon surgical excision, was found to be a nodular lymphocyte predominant Hodgkin lymphoma of the thyroid. So far, thyroid involvement by this variant has never been reported. Upon reporting on this clinical case, the authors emphasize the difficulties usually found in establishing the diagnosis and in defining the best management strategy. A thorough review of the available literature is done. PMID:28044111

    We present an additional sonographic sign of Hashimoto's thyroiditis (HLT), increasing the specificity of this method in pediatric populations. Methods A total of 98 children (mean age 12.7 years, range 7–17 years) were selected from the registry of the endocrinology outpatient department. All subjects met the diagnostic criteria for HLT. All children underwent a prospective thyroid ultrasound examination with special attention paid to the presence of lymph nodes adjacent to the thyroid gland. In order to form a control group, we analyzed 102 healthy volunteers and 94 children with cervical lymphadenopathy, age- and sex-matched with the main study group. Results The ultrasound of the thyroid revealed typical sonographic signs of autoimmune thyroid disease in all children with HLT and in none of the individuals in the control groups. In 96 children (98%) from the HLT group, at least 2 lymph nodes adjacent to the lower part of the thyroid gland lobes localized on one or both sides of the thyroid were detected. No lymph nodes adjacent to the lower part of the thyroid lobes were found in healthy children or children with cervical lymphadenopathy. Conclusions Lymph nodes adjacent to the lower part of the thyroid lobes are an additional ultrasound sign of pediatric Hashimoto's lymphocytic thyroiditis, with 98% sensitivity and 100% specificity.

    Full Text Available Background : Oncocytic follicular (OF cells can be a prominent component of fine needle aspiration (FNA specimens from neoplasms (adenomas and carcinomas and nodules arising in multinodular goiter and chronic lymphocytic thyroiditis (CLT. Because OF cells can be present in non-neoplastic and neoplastic thyroid lesions it can be challenging to differentiate between these two in FNA specimens. The aims of this study were to determine the risk of malignancy in cases diagnosed as either oncocytic follicular neoplasm (OFN or hyperplastic/adenomatoid nodule with OF on FNA and to identify clinicopathologic features that may help in predicting malignancy in such cases, especially the presence or absence of CLT. Design : We retrospectively searched the computerized laboratory information system at our institution between 1998 and 2009 for thyroid US guided FNA specimens in which the term "oncocytic/oncocytes" was mentioned in the final cytopathologic diagnosis. A total of 340 cases were selected for this study. The following data points were collected: Patient demographics, site of thyroid biopsy, size of lesion, FNA diagnosis, histopathologic follow-up and presence of CLT. Surgical pathology follow-up (SPFU was available in 269 (79% cases. Results : Two hundred and sixty patients were females and 80 males (average age 53 years. The lesion size was <3.0 cm in 241 (71% and ≥ 3.0 cm in 99 (29% cases. Cytologic diagnoses included: Follicular neoplasm with oncocytic features (FNOF 321 and suggestive of FNOF 19 cases; a secondary cytologic diagnosis of CLT was made in 20 cases. SPFU was available in 269 (79% cases; it was benign in 213 (213/267 = 79% and malignant in 56 (56/269 = 21% cases. The background thyroid showed CLT in 67 (25% cases; 24% (48/196 neoplasms occurred with versus 76% (147/196 without CLT. The rate of malignancy was lower in nodules measuring less than 3.0 cm as compared to those equal or greater than 3.0 cm in size (17% vs. 28

    Introduction: Chronic lymphocytic thyroiditis [Hashimoto thyroiditis (HT)] is a common thyroid lesion diagnosed on fine-needle aspiration cytology (FNAC). Apart from FNAC, various other parameters, such as clinical features, ultrasonographic findings, antithyroid antibody levels, hormone profiles, and radionuclide thyroid scan, are also taken into consideration in making a diagnosis of HT. Aims: To grade lymphocytic thyroiditis based on the cytomorphology and to correlate the cytological ...

    Full Text Available Multi nodular goitre (MNG is one of the common presentations of various thyroid diseases. Hitherto issue is whether MNG is significantly associated with malignancy. Various studies have reported a 7 to 17% incidence of malignancy in MNG; most common documented is papillary carcinoma. Here we present a case of 40 year old woman with complains of neck swelling, since 10 months. No history of hypertension and other endocrine disorders. The laboratory investigation shows subclinical hyperthyroidism. Ultrasonography (USG of anterior neck showed a hypoechoic nodule at right lobe. Cytological diagnosis of colloid goitre was made and hemithyroidectomy was performed and specimen sent for histopathology. The case on histopathology was diagnosed as papillary microcarcinoma in multinodular goiter with lymphocytic thyroiditis which was further confirmed by immunohistochemistry. Recent studies have suggested that the micro-carcinomas classically progress to a clinically evident disease if left untreated. The treatment of papillary microcarcinoma should be similar to papillary thyroid cancer.

    The controversy on whether or not inflammatory infiltrates in chronic lymphocytic thyroiditis predispose to cancer, has now merged into a debate over the role of the inflammatory infiltrates. The question is how and why some cells become transformed and what factors allow them to spread and in some cases become invasive. Here, we show that the amount of inflammatory mediators such as nitric oxide (NO) and high mobility group Box 1 protein (HMGB1) produced in thyroiditis microenvironment increases in tumors and could be involved in the cellular transformation process. NO and HMGB1 are known to attract macrophages that would promote angiogenesis, matrix remodelling and suppression of an efficient immune response. Inflammatory infiltrates could increase the risk of papillary cancer in patients with autoimmune lymphocytic thyroiditis. Cytokines and soluble inflammatory mediators involved in cancer-related inflammation are not only a target for innovative diagnostic and therapeutic strategies but they also represent a future challenge for oncologists.

    Full Text Available Abstract Background Clinical, biochemical, ultrasonographic, radionuclide and cytomorphological observations in Lymphocytic thyroiditis (LT, to define the cytological grading criteria on smears and correlation of grades with above parameters. Methods This prospective study was conducted on 76 patients attending the Fine needle aspiration cytology clinic of a tertiary care institute in North India. The various parameters like patients' clinical presentation, thyroid antimicrosomal antibodies, hormonal profiles, radionuclide thyroid scan and thyroid ultrasound were studied. Fine needle aspiration of thyroid gland and grading of thyroiditis was done on smears. The grades were correlated with above parameters and the correlation indices were evaluated statistically. Results Most of the patients were females (70, 92.11% who presented with a diffuse goiter (68, 89.47%. Hypothyroid features (56, 73.68% and elevated TSH (75, 98.68% were common, but radioiodide uptake was low or normal in majority of patients. Thyroid antimicrosomal antibody was elevated in 46/70 (65.71% patients. Cytomorphology in fine needle aspirates was diagnostic of lymphocytic thyroiditis in 75 (98.68% patients. Most of them had grade I/II disease by cytology. No correlation was observed between grades of cytomorphology and clinical, biochemical, ultrasonographic and radionuclide parameters. Conclusion Despite the availability of several tests for diagnosis of LT, FNAC remains the gold standard. The grades of thyroiditis at cytology however do not correlate with clinical, biochemical, radionuclide and ultrasonographic parameters.

    Full Text Available Introduction: Chronic lymphocytic thyroiditis [Hashimoto thyroiditis (HT] is a common thyroid lesion diagnosed on fine-needle aspiration cytology (FNAC. Apart from FNAC, various other parameters, such as clinical features, ultrasonographic findings, antithyroid antibody levels, hormone profiles, and radionuclide thyroid scan, are also taken into consideration in making a diagnosis of HT. Aims: To grade lymphocytic thyroiditis based on the cytomorphology and to correlate the cytological grades with the levels of antithyroid peroxidase antibody (ATPO, antithyroglobulin antibody (ATG, and thyroid stimulating hormone (TSH. Materials and Methods: During a period of one and half years, 1,667 cases underwent FNAC of thyroid at our tertiary care center. Of these, 128 cases had cytological evidence of lymphocytic thyroiditis. Out of these, in 60 cases the levels of ATPO, ATG, and TSH were known. The cytological grades of lymphocytic thyroiditis in these cases were correlated with these parameters. Results: Out of the 60 cases, 55 were females. Age ranged from 5 years to 70 years, with majority of patients in third decade. Diffuse enlargement of thyroid was the commonest presentation. However, 14 cases presented with nodular disease. Majority of the patients had grade 1 thyroiditis (27 cases, followed by grade 2 thyroiditis (22 cases. Cytomorphology was diagnostic of thyroiditis in all 60 cases. ATPO was elevated in 57 cases and ATG was elevated in 40 cases. Elevated level of TSH was seen in only 18 cases. In 39 cases, TSH value was normal. There was no correlation between the cytological grades of thyroiditis and the levels of antithyroid antibodies and TSH. Conclusion: Lymphocytic infiltration of thyroid follicles is pathognomonic of lymphocytic thyroiditis. Positivity for antithyroid antibodies is strongly associated with HT but no correlation was observed between the grades of thyroiditis and the levels of ATPO, ATG, and TSH.

  11. Cytomorphological features of oncocytic variant of papillary thyroid carcinoma with lymphocytic thyroiditis

    Full Text Available Cytological diagnosis of hurthle cell lesions of thyroid is a diagnostic dilemma. Presence of hurthle cells on fine needle aspiration (FNA leads to a wide range of differential diagnosis including benign and malignant entities. The oncocytic variant of papillary thyroid carcinoma (PTC is one entity of the vast list of differentials of which very few cases have been reported to date. We report a case of oncocytic variant of PTC in a 28-year-old female diagnosed on cytomorphology. The findings of FNA smears of the first aspirate were not sufficient for a definitive diagnosis. Repeat FNA was done to rule out the possibility of autoimmune thyroiditis/thyroid neoplasm. The repeat FNA smears showed oncocytic cells present in papillary and loosely cohesive clusters. Many of the cells displayed nuclear features of PTC and the case was finally diagnosed as PTC; oncocytic variant. Thyroidectomy specimen revealed PTC; oncocytic variant with lymphocytic thyroiditis in the surrounding tissue. Thus, in cytology practice, concurrent autoimmune thyroiditis may pose a problem in diagnosis of PTC; oncocytic variant.

    Fahr syndrome (FS) refers to basal ganglia calcification that is associated with many neurological and psychiatric abnormalities and appears as secondary to other diseases. We described a case of FS patient who was admitted in the Department of Neurology of "Prof. Dr. Nicolae Oblu" Clinical Emergency Hospital, Iassy, Romania, with seizure and mood disorders. On CT, the cause of seizure was found to be the bilateral calcifications of cerebellum, basal ganglia, thalamus and internal capsule. As the patient died after 15 days of hospitalization due to new seizures and gastrointestinal infection, an autopsy was made. Grossly, there were bilateral symmetrically gritty yellow areas in basal ganglia, thalami, internal capsule, cerebral cortex, cerebellar folia, dentate nucleus, and brain stem. A detailed histopathological examination revealed five types of calcium deposits within the walls of capillaries, small and medium-sized arteries from the intracerebral affected areas, chronic lymphocytic thyroiditis and fibro-adipose tissue instead of parathyroids. We consider that intracerebral symmetrical calcifications were the results of the hypoparathyroidism determined by an ancient autoimmune parathyroiditis that evolved to fibrosis as at microscopy we found an autoimmune thyroiditis.

    The goal of this study is to determine the clinicopathologic differences in patients with papillary thyroid carcinoma (PTC) with or without chronic lymphocytic thyroiditis (CLT). We reviewed the medical records of 195 consecutive PTC patients who underwent total thyroidectomy and bilateral central lymph node dissection from April 2008 to March 2010. The differences in clinicopathologic factors, such as age, gender, size of primary tumor, perithyroidal invasion, lymphovascular invasion, capsular invasion, and central lymph node (CLN) metastasis, were analyzed in PTC patients with or without CLT. Among 195 patients, 56 (28.7%) had co-existing CLT. Patients with CLT had the following characteristics as compared to patients without CLT: significantly younger, female predominance, smaller tumor size, and lower incidence of capsular invasion (p = 0.038, 0.006, 0.037, and 0.026, respectively). Also, patients with CLT (12.5%) had a significantly lower incidence of CLN metastases than patients without CLT (28.1%; p = 0.025) based on univariate analysis. Moreover, multivariate analysis showed that younger age (p = 0.042, odds ratio = 1.033) and female gender (p = 0.012, odds ratio = 6.865) are independent clinical factors in patients with CLT compared to patients without CLT. CLT was shown to be commonly associated with PTC. Compared to patients with PTC without CLT, patients with CLT were younger with a female predominance, which are the most important and well-known prognostic variables for thyroid cancer mortality.

    It has been reported that papillary thyroid carcinoma (PTC) with chronic lymphocytic thyroiditis (CLT) is less associated with extrathyroidal extension (ETE), advanced tumor stage and lymph node (LN) metastasis. Other studies have suggested that concurrent CLT could antagonize PTC progression, even in BRAF-positive patients. Since the clinical significance of the BRAF mutation has been particularly associated with conventional PTC, the purpose of this study was to determine the clinical significance of CLT according to BRAF mutation status in conventional PTC patients. We retrospectively reviewed the medical records of 3332 conventional PTC patients who underwent total thyroidectomy with bilateral central neck dissection at the Thyroid Cancer Center of Samsung Medical Center between January 2008 and June 2015. In this study, the prevalence of BRAF mutation was significantly less frequent in conventional PTC patients with CLT (76.9% vs 86.6%). CLT was an independent predictor for low prevalence of ETE in both BRAF-negative (OR=0.662, P=0.023) and BRAF-positive (OR=0.817, P=0.027) conventional PTC patients. In addition, CLT was an independent predictor for low prevalence of CLNM in both BRAF-negative (OR=0.675, P=0.044) and BRAF-positive (OR=0.817, P=0.030) conventional PTC patients. In conclusion, BRAF mutation was significantly less frequent in conventional PTC patients with CLT. However, CLT was an independent predictor for less aggressiveness in conventional PTC patients regardless of BRAF mutation status.

    The study aimed to identify the clinical characteristics of coexisting chronic lymphocytic thyroiditis (CLT) in papillary thyroid carcinoma (PTC) and to evaluate the influence on prognosis. A total of 1,357 patients who underwent thyroid surgery for PTC were included. The clinicopathological characteristics were identified. Patients who underwent total thyroidectomy (n = 597) were studied to evaluate the influence of coexistent CLT on prognosis. Among the total 1,357 patients, 359 (26.5%) had coexistent CLT. In the CLT group, the prevalence of females was higher than in the control group without CLT (P < 0.001). Mean tumor size and mean age in the patients with CLT were smaller than without CLT (P = 0.040, P = 0.047, respectively). Extrathyroidal extension in the patients with CLT was significantly lower than without CLT (P = 0.016). Among the subset of 597 patients, disease-free survival rate in the patients with CLT was significantly higher than without CLT (P = 0.042). However, the multivariate analysis did not reveal a negative association between CLT coexistence and recurrence. Patients with CLT display a greater female preponderance, smaller size, younger and lower extrathyroidal extension. CLT is not a significant independent negative predictive factor for recurrence, although presence of CLT indicates a reduced risk of recurrence.

    Background Papillary thyroid carcinoma (PTC) is frequently accompanied by lymphocytic thyroiditis (LT). Some reports claim that Hashimoto’s thyroiditis (the clinical form of LT) enhances the likelihood of PTC; however, others suggest that LT has antitumor activity. This study was aimed to find out the relationship between the patterns of helper T cell (Th) cytokines in thyroid tissue of PTC with or without LT and the clinicopathological manifestation of PTC. Methods Fresh surgical samples of PTC with (13 cases) or without (10 cases) LT were used. The prognostic parameters (tumor size, extra-thyroidal extension of PTC, and lymph node metastasis) were analyzed. The mRNA levels of two subtypes of Th cytokines, Th1 (tumor necrosis factor α [TNF-α], interferon γ [IFN-γ ], and interleukin [IL] 2) and Th2 (IL-4 and IL-10), were analyzed. Because most PTC cases were microcarcinomas and recent cases without clinical follow-up, negative or faint p27 immunoreactivity was used as a surrogate marker for lymph node metastasis. Results PTC with LT cases showed significantly higher expression of TNF-α (p = .043), IFN-γ (p < .010), IL-4 (p = .015) than those without LT cases. Although the data were not statistically significant, all analyzed cytokines (except for IL-4) were highly expressed in the cases with higher expression of p27 surrogate marker. Conclusions These results indicate that mixed Th1 (TNF-α, IFN-γ , and IL-2) and Th2 (IL-10) immunity might play a role in the antitumor effect in terms of lymph node metastasis. PMID:27681413

    Sclerosing lymphocytic lobulitis (SLL) is a rare inflammatory disorder, which is also known as fibrous mastopathy and lymphocytic mastitis. It is commonly associated with autoimmune disorders, particularly type 1 diabetes and thyroiditis. We report the case of a 28-year-old woman diagnosed as SLL with Hashimoto's thyroiditis, but without diabetes. She presented suspicious microcalcifications without palpable mass in routine mammograms in both breasts. She had been diagnosed as Hashimoto's thyroiditis several years before and had been followed up in endo-clinics.

    The objective of the study was to evaluate whether texture analysis using histogram and gray level co-occurrence matrix (GLCM) parameters can help clinicians diagnose lymphocytic thyroiditis (LT) and differentiate LT according to pathologic grade. The background thyroid pathology of 441 patients was classified into no evidence of LT, chronic LT (CLT), and Hashimoto's thyroiditis (HT). Histogram and GLCM parameters were extracted from the regions of interest on ultrasound. The diagnostic performances of the parameters for diagnosing and differentiating LT were calculated. Of the histogram and GLCM parameters, the mean on histogram had the highest Az (0.63) and VUS (0.303). As the degrees of LT increased, the mean decreased and the standard deviation and entropy increased. The mean on histogram from gray-scale ultrasound showed the best diagnostic performance as a single parameter in differentiating LT according to pathologic grade as well as in diagnosing LT.

    It is known that the prevalence of lymphocytic thyroiditis (LT) is higher in patients with papillary thyroid carcinoma (PTC), that gender influences this association, and that certain features of PTC occur more frequently in patients who also have LT. These relationships have not been studied in patients with papillary thyroid microcarcinomas (PTMC), however. Therefore, we performed a study to compare the clinical and pathological features of patients with PTMC who did and did not have LT. We collected the 323 consecutive patients following excision of PTMC diagnosed as papillary carcinoma on preoperative needle aspiration cytology. We analyzed the demographic, serologic, and pathologic data of those cases with categorization into four groups based on presence of LT and neck lymph node metastasis. In all PTMC, the presence of LT did not influence the frequency of lymph node metastasis (27 of 105 [25.7%] vs. 48 of 218 [22.0%]). Among the patients with metastatic PTMC, LT was noted significantly more often in female than male patients (95.2% vs. 79.8%). In metastatic PTMC, multifocality and bilaterality was more frequent in with LT than without LT (44.4% vs. 29.2%; 29.6% vs. 14.6%). Both the presence of serum thyroglobulin antibody (TgAb; p = 0.016) and serum microsomal antibody (p = 0.013) were highly correlated with the presence of LT. Twenty-seven of 105 patients (25.7%) with PTMC with LT had nodal metastasis. Co-existing LT was noted predominantly in women, influenced more often multifocality and bilaterality of tumors, and higher frequency of metastasis to lateral compartment lymph nodes.

    Autoimmune thyroid disease (AITD) has been associated with other autoimmune diseases such as chronic urticaria, insulin-dependent diabetes mellitus, Sjøgren's syndrome, inflammatory bowel disease, rheumatoid arthritis, multiple sclerosis, systemic lupus erythematosus, psoriasis, ankylosing spondylitis, and dermatomyositis (DM). AITD is a common disorder affecting primarily women, and both genetic and environmental factors are included in its pathogenesis. DM is considered an autoimmune disease of the muscles and skin. Although AITD is the most common cause of hypothyroidism, to the best of our knowledge, only three cases of DM and AITD in the same patient have been reported in the last 40 years. We consider that both are developed from the same autoimmune background. Herein, we present a case of a 30-year-old man with a 4-year history of AITD who was diagnosed as suffering as well from DM.

    To monitor the extent and the duration of lymphocyte subset changes in patients with thyroid carcinoma undergoing therapeutic 131I administration, the percentage of lymphocyte subsets were serially analyzed before and after 131I treatment. In patients who received 1850 MBq of 131I for ablation of thyroid remnants, only for NK cells and B cells showed a significant reduction. In patients received 3700 MBq of 131I for treatment of local lymph node metastases, NK cells, B cells and CD4+ were found decreased. In patients received 7400 MBq of 131I for treatment of distant metastases, NK cells, B cells and CD4+ and CD8+ were all affected. However, there is no significant reduction compared to the baseline in the percentage of all lymphocyte subsets three months after 131I treatment. The results show that the sensitivity of lymphocytes to 131I internal radiation depends upon lymphocyte phenotype and 131I activity. The immunosuppression effects are temporary and reversible.

    Full Text Available We present an additional sonographic sign of Hashimoto’s thyroiditis (HLT, increasing the specifi city of this method in pediatric populations. Methods: A total of 98 children (mean age 12.7 years, range 7–17 years were selected from the registry of the endocrinology outpatient department. All subjects met the diagnostic criteria for HLT. All children underwent a prospective thyroid ultrasound examination with special attention paid to the presence of lymph nodes adjacent to the thyroid gland. In order to form a control group, we analyzed 102 healthy volunteers and 94 children with cervical lymphadenopathy, age- and sex-matched with the main study group. Results: The ultrasound of the thyroid revealed typical sonographic signs of autoimmune thyroid disease in all children with HLT and in none of the individuals in the control groups. In 96 children (98% from the HLT group, at least 2 lymph nodes adjacent to the lower part of the thyroid gland lobes localized on one or both sides of the thyroid were detected. No lymph nodes adjacent to the lower part of the thyroid lobes were found in healthy children or children with cervical lymphadenopathy. Conclusions: Lymph nodes adjacent to the lower part of the thyroid lobes are an additional ultrasound sign of pediatric Hashimoto’s lymphocytic thyroiditis, with 98% sensitivity and 100% specifi city.

    Two patients with persistent lymphocytic thyroiditis and thyrotoxicosis were studied. Both patients presented with severe hyperthyroidism of nine months' duration and had nontender, small thyroid glands. Uptake of radioactive iodine (131I) was consistently low. Serum thyroxine and triiodothyronine levels remained elevated without remission until thyroidectomy. The serum thyroglobulin level was normal, but testing for microsomal antibody gave weakly positive results in one case. Thyroglobulin and thyroid stimulatory antibodies were not found. The ratio of helper to suppressor T cells was elevated in one case. Neither patient showed response to propranolol, prednisone, or iodine. Light microscopic and immunohistologic studies showed severe lymphocytic thyroiditis with formation of secondary lymphoid follicles. Lymphocytes were predominately T cells (OKT11-positive), primarily helper/inducer T cells (OKT4-positive). Hyperplastic nodules contained high immunoreactive thyroglobulin and thyroxine levels. Aberrant thymus was seen within the thyroid. These studies suggest the possibility of intrathyroidal stimulation and hydrolysis of thyroglobulin within thyroid cells and also support the hypothesis that T and B cell immunoregulatory defects are important in the pathogenesis of this disease.

    Diffuse increased uptake on 18F-Fluorodeoxyglucose Positron Emission Tomography (18F FDG PET) is a well-known finding of the lymphocytic thyroiditis. Nevertheless, a pathologic confirmation is needed in cases of a focal 18F FDG uptake in the thyroid gland. This article reports a rare case of a focal 18F FDG uptake lesion by PET, which was revealed pathologically to be lymphocytic thyroiditis

    This is a case of a 44-year-old woman with an anterior neck mass and hypothyroidism who presented with an incidental finding of an elevated serum calcium level and was found to have primary hyperparathyroidism and osteoporosis. During surgical exploration no parathyroid adenoma was found, although a nodule was palpated within the right thyroid lobe. Examination of the excised right thyroid lobe revealed an intrathyroidal parathyroid adenoma and chronic lymphocytic thyroiditis. After surgery, she did not develop severe hypocalcaemia and this was attributed to preoperative treatment with pamidronate. In the months following surgery, parathyroid hormone remained undetectable.

    Tuberculosis of thyroid gland is a very rare disease. It has variable presentations and may be sometimes associated with autoimmune thyroiditis. We report a case of 45-year-old male, with left sided painless neck swelling, with a purulent discharging sinus over it associated with night sweats and loss of appetite. Thyroid imaging disclosed heterogeneous enhancement of left lobe of thyroid gland with internal vascularity and coarse calcifications. Core needle biopsy revealed caseous necrosis and AFB positivity. Patient had thyroid peroxidase antibody and thyroglobulin antibody positivity and the rest of thyroid function tests were normal. Patient had positive Mantoux test, hepatitis B surface Ag, and low viral DNA. The patient was diagnosed as being a case of tuberculous abscess of thyroid gland and was put on antitubercular therapy for 2 months. Patient subsequently underwent left hemithyroidectomy when there was no response. Histopathological examination revealed tuberculosis of thyroid gland. A final diagnosis of tuberculous abscess of thyroid gland in a background of Hashimoto's thyroiditis in a chronic HBV carrier was made. Therefore, although rare tuberculosis of thyroid should be kept in mind as a differential diagnosis of thyroid swelling. PMID:28101393

To determine the expression of chemokine receptors in lymphocytes from thyroid nodules and peripheral blood in patients with and without Hashimoto’s thyroiditis (HT. Patients and Methods. The study included 46 women with thyroid nodules and HT and 60 women with thyroid nodules without HT (controls who underwent a fine needle aspiration biopsy (FNAB. Expression of chemokine receptors CXCR3, CCR5, and CRTH2 was assessed by flow cytometry in lymphocytes from FNAB samples and from peripheral blood. Results. The percentage of CRTH2+ lymphocytes was higher in nodules with HT in comparison with controls, both in FNAB samples (13.95 versus 6.7%, p=0.008 and in peripheral blood (6.7 versus 5.13%, p=0.047, and positively correlated with serum antibodies to thyroid peroxidase (r=0.243; p=0.026 and negatively correlated with thyroid volume (r=-0.346; p=0.008. Lymphocytes from neoplastic nodules showed a higher expression of both CXCR3 and CCR5 than those from hyperplastic ones. Conclusion. Flow cytometry performed in FNAB samples may serve as a good tool in investigation of intrathyroidal expression of immunological parameters. In our study, the CRTH2 expression on thyroid-infiltrating lymphocytes as well as on lymphocytes from peripheral blood was increased in HT as compared to controls.

    Human T lymphocytes expose ionotropic and metabotropic glutamate receptors, which control immune responses, cell activation, maturation, and death. Several cytokines release during inflammation which identification may have important physiological and clinical implications. Main biological function of IL-10 is limitation and termination of inflammatory responses and the regulation of differentiation and proliferation of several immune cells. Various inflammatory molecules regulated the secretion of IL-8 and IL-10, but the action of glutamate on the biosynthesis of cytokines is unknown. We have found that in peripheral blood lymphocytes glutamate at the concentrations within normal plasma levels (1 x 10(-5) M), as well as at lower concentration (0.3 x 10(-6) M) changes the secretion of immunosuppressive cytokine IL-10, whereas synthesis of proinflammatory chemokine, IL-8 did not changed significantly. Moreover, our results have shown that peripheral blood lymphocytes from patients with autoimmune thyroiditis release less IL-10 at both concentration of glutamate than peripheral blood lymphocytes from healthy persons. These data suggest that glutamate decrease the secretion of IL-10 by peripheral blood lymphocytes, especially in patients with autoimmune thyroiditis that may be responsible for prolongation of inflammation.

    Whether or not autoimmune thyroid disease influences the progression of differentiated thyroid cancer (DTC) remains controversial. Findings of previous studies are influenced by lead time bias and/or procedure bias selection. These biases can be reduced by studying a single-institution patient population that underwent a similar extent of surgical resection. From a cohort of 660 patients with DTC who underwent thyroidectomy, we retrospectively studied 357 patients who underwent total thyroidectomy and central compartment node dissection (CCND) for DTC between 2003 and 2013. Forty-one percent (140/345) of study patients had lymphocytic thyroiditis (LT), and 30% (91/301) had serum positive for thyroglobulin antibody (TgAb). LT was reported in 78% of the TgAb-positive cases. Sixty percent (213/357) of cases had metastatic thyroid carcinoma in 1 or more neck lymph nodes (55% [198/357] central compartment, and 22% [77/356] lateral compartment). Patients with LT had fewer metastatic cervical lymph nodes than those with no LT (2.7 ± 4.7 vs 3.5 ± 4.8, respectively, P = .0285). Patients with positive TgAb and thyroiditis had a larger number of benign cervical lymph nodes removed than those with negative TgAb or no LT. No significant difference was observed in age, tumor size, multifocality, extrathyroidal extension, vascular invasion, or frequency of cervical lymph node metastasis between TgAb-negative and -positive cases or between cases with and without LT. Lymphocytic thyroiditis is associated with fewer central neck compartment metastatic lymph nodes and a larger number of excised reactive benign cervical lymph nodes. Whether this association indicates a protective role of thyroid autoimmunity in lymph node spreading remains unclear. CCND = central compartment node dissection DTC = differentiated thyroid cancer HT = Hashimoto thyroiditis LT = lymphocytic thyroiditis TgAb = thyroglobulin antibody TPO = thyroid peroxidase.

    The aim was to assess changes of B and T lymphocytes and selected apoptotic markers in Hashimoto thyroiditis (HT) cases on the basis of quantitative immunohistochemical studies (CD20, CD43, CD8, Bcl-2, caspase-3). The control group comprised colloid goitres without inflammatory infiltrate taken from 10 female patients. Thyroid specimens were obtained retrospectively from 40 patients. The immunohistochemical reactions were subject to quantitative evaluation performed using image-processing methods, including a spatial visualisation of the markers' expression. The percentage of Bcl-2 reactions in HT (mean 3.65%, SD 2.94%) was significantly lower than in the control group (mean 13.99%, SD 5.04%), while the thyroid follicles in HT samples exhibited a higher degree of staining for caspase-3 (mean 1.10%, SD 1.03%) in contrast to normal control tissues (mean 0.48%, SD 1.02%). The results from this study indicate that apoptosis plays a major role in the patogenesis of autoimmune thyroid diseases containing the main pathogenic events in the lesion of thyroid follicular cells in HT. Moreover, the reactivity of CD43 and CD20 was significantly higher in Hashimoto disease, while CD8 was not significantly different from the control group.

    Chronic lymphocytic thyroiditis and vitiligo often occur in association and seem to be characterized by a prevalent Th1-driven autoimmune process. The aim of this study is to analyze selected intracellular Τh1 and Th2 cytokines in patients with Hashimoto?s thyroiditis when associated with non-segmental vitiligo. We analyzed intracellular interleukin-2, interferon-gamma (Τh1) and interleukin-4 (Th2), in peripheral blood lymphocytes of 23 patients with isolated Hashimoto?s thyroiditis (group A) and of 11 patients with Hashimoto?s thyroiditis associated with non-segmental vitiligo (group B). Peripheral blood lymphocytes were stimulated and incubated with specific monoclonal antibodies. Intracellular cytokines were assayed by flow cytometric analysis. Interleukin-2 and interferon-gamma positive cells were increased in almost all patients but the median values were similar in patients with isolated Hashimoto?s thyroiditis and in those with concurrent vitiligo. In contrast, the number of patients with increased interleukin-4 positive cells was higher in patients with thyroiditis and vitiligo (9/11) than in those with isolated thyroiditis (2/23; plymphocytes characterize Hashimoto?s thyroiditis when associated with non-segmental vitiligo, suggesting a modified balance from highly prevalent Th1 to mixed Th1/Th2 subset.

    In chronic lymphocytic thyroiditis (CLT), the follicular epithelial cells display cytological atypia resembling papillary thyroid carcinoma (PTC), and epidemiological studies have suggested an increased risk of PTC in patients with this condition. While reactive atypia is observed diffusely in CLT-affected thyroid parenchyma, it is not unusual to find microscopic foci morphologically distinct from the surrounding parenchyma, exhibiting more pronounced cytological and architectural atypia. These small atypical lesions, which we term "follicular epithelial dysplasia" (FED), are particularly prominent in cases of severe CLT, yet lack invasive growth, papillary architecture, or intranuclear pseudoinclusions. To gain further insight into their biological significance, we constructed a tissue microarray of 70 cases of CLT, comprised of morphologically normal thyroid, thyroid with reactive atypia, FED, follicular nodular disease (nodular hyperplasia or follicular adenoma), and PTC. Immunohistochemical staining was performed for a marker panel including PTC (HBME-1, cytokeratin 19, galectin-3, and cyclin-D1) as well as TTF-1, thyroglobulin, and p63. Slides were digitally scanned and immunohistochemical staining evaluated using automated image analysis software. FED lesions were positive for TTF-1 and thyroglobulin (50/50, 100 %), though some (13/50, 26 %) also expressed p63. Similar to PTC, strong diffuse staining was observed for HBME-1 (43/50, 86 %), cytokeratin 19 (48/50, 96 %), galectin-3 (20/50, 40 %) and cyclin-D1 (38/50, 76 %). In contrast, normal thyroid, reactive atypia, and follicular nodular disease were negative, or at most, exhibited focal weak staining for HBME-1, cytokeratin 19, and galectin-3. The results of this study demonstrate the presence of atypical microscopic lesions in CLT with an immunohistochemical profile similar to PTC, supporting the concept of a premalignant lesion preceding PTC, arising in the context of severe chronic inflammation.

    慢件淋巴细胞件甲状腺炎于1912年由日本学者首先报道,属于最常见的自身免疫性甲状腺疾病,也是甲状腺功能减退(甲减)最主要的病因,好发于中老年女性.患者起病隐匿,常无特征性的临床表现,容易漏诊.本病诊断尚缺乏国际统一标准,主要依靠一些非特异性的症状与体征,尤其是甲状腺肿大、甲状腺功能减退,并结合相应的辅助检查.如甲状腺自身抗体阳性,且滴度较高,对诊断意义更大.甲状腺穿刺细胞学检查不作为常规项目,但对诊断困难者具有确诊价值.伴有甲减者,需要常规采用替代治疗,尤其是甲状腺肿大明显者、孕妇以及儿童可以给予左旋甲状腺素替代治疗,但仅有亚临床甲减者,或甲状腺功能正常而甲状腺自身抗体阳性的患者是否需要治疗尚存在争议.%Chronic lymphocytic thyroiditis (CLT), which is reported by Japanese scientist Hashimoto in 1912, is an autoimmune thyroid disease characterized by the destruction of thyroid gland,hypothyroidism and female dominance. The disease is usually insidious onset with no specific clinical manifestations. CLT can be diagnosed based on enlarged thyroid, positive thyroid autoantibodies and hypothyroidism,though no identical diagnostic criteria is currently available. Fine needle aspiration and cytology is useful for the confirmation of CLT, and could be applied in patients with diagnostic difficulty. Thyroid hormone replacement therapy should be introduced in patients with hypothyroidism, especially in pregnant women, children and cases with overt thyroid enlargement. Treatment with thyroxine in patients with subclinical hypothyroidism and euthyroid patients with positive thyroid autoantibedies remains controversial.

    The association between neutrophil-to-lymphocyte ratio (NLR) and differentiated thyroid cancer (DTC) is undecided. To rectify this question, we conducted a systematic meta-analysis based on 7 prospective cohort studies published between 2013 and 2015, comprising 7349 patients. Six of these cohorts included pretreatment (baseline) NLR data for patients with thyroid nodules. The meta-analysis of these 6 cohorts showed that the NLR of patients with DTC (4617 cases) was statistically similar to patients with benign nodules only (1666 cases), with a mean difference (MD) of 0.19 (95% CI: −0.09 to 0.46; I2 = 93%; P thyroid carcinoma in patients stratified by age <45 and ≥45 years (496 and 891 cases, respectively); the pooled MD was 0.09 (95% CI: −0.37 to 0.55; I2 = 92.2%, P < 0.001). An elevated NLR seems not a reliable indicator of progressing DTC in patients with goiters, and there was no difference in NLR between patients aged <45 years and those aged ≥45 years. Well-designed and large-scale investigations are warranted to understand the value of NLR in the prognosis of DTC. PMID:27941815

    This report documents 3 pediatric papillary thyroid carcinoma cases with associated Hashimoto thyroiditis. In all 3 cases, hypoechoic nodules accompanied by multiple echogenic spots were noted on sonography of the thyroid. Hashimoto thyroiditis was suspected on the basis of positive thyroid autoantibody test results and pathologic examinations of thyroidectomy specimens, which revealed chronic thyroiditis with lymphocytic infiltration as the background of papillary thyroid carcinoma development. The potential for papillary carcinoma development warrants close follow-up, and meticulous sonographic examinations must be performed in children with Hashimoto thyroiditis.

    A disparity in gender incidence has been reported in both papillary thyroid carcinoma (PTC) and chronic lymphocytic thyroiditis (CLT) diseases frequently associated and whose incidence has been increasing in parallel. We aimed to analyze differences in morphometric variables between male and female PTC patients and their relationship with the presence of concurrent CLT. The nuclear texture features of 100 hematoxylin-eosin stained nuclei from 100 consecutive classic PTC patients enrolled in our service were compared with their clinical and pathological features, including the presence of CLT. All patients were submitted to a standard management protocol and followed-up for 13-248 months (Mo = 117 months). Chromatin in women tended to present a denser and more homogeneous structure, in a less mottled pattern, with higher values of energy (p = 0.008) and diagonal moment (p = 0.032) than men. Concurrent CLT was more prevalent in women (41.42%) than in men (13.33%, p = 0.04) and was associated with higher cluster prominence values (p = 0.027), a parameter that indicates a predominance of high nuclear contrasted heterochromatin. A multivariate logistic regression analysis showed that higher cluster prominence was independently correlated with chromatin in patients who presented CLT but did not demonstrate any association between concurrent CLT and gender. We were unable to demonstrate any association between gender and any characteristic of tumor aggressiveness or patients outcome. Our results suggest that chromatin texture of hematoxylin-eosin stained nuclei in paraffin sections of PTC cells is related to both gender and concurrent CLT.

    Expression of cytokine-regulated signal transducer and activator of transcription (STAT) proteins was histochemically assessed in patients diagnosed as having Hashimoto's disease or focal lymphocytic thyroiditis (n = 10). All surgical specimens showed histological features of lymphocytic thyroiditis, including a diffuse infiltration with mononuclear cells and an incomplete loss of thyroid follicles, resulting in the destruction of glandular tissue architecture. Immunohistochemical analysis demonstrated differential expression patterns of the various members of the STAT transcription factors examined, indicating that each member of this conserved protein family has its distinct functions in the development of the disease. Using an antibody that specifically recognized the phosphorylated tyrosine residue in position 701, we detected activated STAT1 dimers in numerous germinal macrophages and infiltrating lymphocytes as well as in oncocytes. In contrast, STAT3 expression was restricted to epithelial cells and showed a clear colocalization with the antiapoptotic protein Bcl-2. Moreover, expression of phospho-STAT3 was associated with low levels of stromal fibrosis, suggesting that STAT3 serves as a protective factor in the remodeling of the inflamed thyroid gland. Phospho-STAT5 immunoreactivity was detected in numerous infiltrating cells of hematopoietic origin and, additionally, in hyperplastic follicular epithelia. This tissue distribution demonstrated that activated STAT5 molecules participate in both lymphocytopoiesis and possibly also in the buildup of regenerating thyroid follicles. Taken together, the cell-type-specific expression patterns of STAT proteins in human lymphocytic thyroiditis reflect their distinct and partially antagonistic roles in orchestrating the balance between degenerating and regenerating processes within a changing cytokine environment.

    The aim of the present study was to compare the multidetector computed tomography (MDCT) features of benign and malignant nodules in patients with chronic lymphocytic thyroiditis (CLT). MDCT findings, including the size, solid percentage, calcification, margin, capsule, anteroposterior-transverse diameter ratio as well as the mode and the degree of enhancement of 137 thyroid nodules in 127 CLT cases were retrospectively analyzed. Furthermore, the correlation between MDCT findings and pathological results combined with the CT perfusion imaging was analyzed for the differences between benign and malignant nodules. A total of 77.5% (31/40) of malignant nodules were completely solid, and 33% (32/97) of benign nodules were predominantly cystic. Compared with the benign nodules, micro-calcification and internal calcification were more frequently observed in the malignant nodules (P0.05). MDCT features are useful in differentiating the benign and malignant nodules in CLT patients, and it may be essential for a radiologist to review the MDCT characteristics of nodules in the clinical practice.

    In our previous studies, resolution of granulomatous experimental autoimmune thyroiditis (G-EAT) was promoted when thyroid epithelial cells were protected from Fas-mediated apoptosis due to transgenic overexpression of FLIP. We hypothesized that if FLIP were overexpressed on lymphocytes, CD4(+) effector cells would be protected from Fas-mediated apoptosis, and resolution would be delayed. To test this hypothesis, we generated transgenic (Tg) mice overexpressing FLIP under the CD2 promoter. Transgenic FLIP was expressed on CD4(+) and CD8(+) T cells and B cells. Transgenic overexpression of FLIP protected cultured splenocytes from Fas-mediated, but not irradiation-induced, apoptosis in vitro. Unexpectedly, Tg(+) donor cells transferred minimal G-EAT, which was partially overcome by depleting donor CD8(+) T cells. When Tg(+) and Tg(-) donors transferred equivalent disease, G-EAT resolution was delayed in FLIP transgenic mice. However, CD2-FLIP Tg(+) donors often transferred less severe G-EAT, even after depletion of CD8(+) T cells. This influenced the rate of G-EAT resolution, resulting in little difference in G-EAT resolution between groups. Tg(+) mice always had reduced anti-mouse thyroglobulin autoantibody responses, compared with Tg(-) littermates, presumably because of FLIP overexpression on B cells. These results suggest that effects of transgenic FLIP on a particular autoimmune disease vary, depending on what cells express the transgene and whether those cells are effector cells or if they function to modulate disease.

  5. Thyrocytes responding to IFN-gamma are essential for development of lymphocytic spontaneous autoimmune thyroiditis and inhibition of thyrocyte hyperplasia.

    IFN-gamma promotes the development of lymphocytic spontaneous autoimmune thyroiditis (L-SAT) in NOD.H-2h4 mice and inhibits the development of thyrocyte hyperplasia and proliferation (TEC H/P). The precise mechanisms by which IFN-gamma promotes L-SAT and inhibits TEC H/P are unknown. To determine whether responsiveness of lymphocytes or thyrocytes to IFN-gamma is important for the development of these lesions, IFN-gammaR-/- mice, which develop TEC H/P similar to IFN-gamma-/- mice, were used as recipients for adoptive cell transfer. Wild-type (WT) splenocytes or bone marrow induced L-SAT and inhibited TEC H/P in IFN-gamma-/-, but not IFN-gammaR-/- recipients. IFN-gammaR-/- recipients of WT cells developed severe TEC H/P, but did not develop L-SAT, suggesting that thyrocytes responding to IFN-gamma are important for inhibition of TEC H/P. Unexpectedly, IFN-gammaR-/- splenocytes or bone marrow did not induce L-SAT in IFN-gamma-/- or WT mice even though IFN-gammaR-/- lymphocyte donors produced as much IFN-gamma as lymphocytes from WT donors, and thyrocytes could respond to IFN-gamma. Real-time PCR indicated that recipients of IFN-gammaR-/- bone marrow expressed less mRNA for IFN-gamma-inducible chemokines compared with recipients of WT bone marrow. This might limit the migration of IFN-gammaR-/- lymphocytes to thyroids. Few IFN-gammaR-/- lymphocytes infiltrated thyroids even in the presence of WT lymphocytes, suggesting that lymphocytes unable to respond to IFN-gamma are not induced to migrate to thyroids. These results suggest that thyrocytes must be able to respond to IFN-gamma for the development of L-SAT and inhibition of TEC H/P, and lymphocytes must be able to respond to IFN-gamma to induce L-SAT.

    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.

    The incidence of Hashimoto's thyroiditis (HT) seems to have increased over the last several decades. Since there is a lack of recent studies in the literature that evaluate this phenomenon on a histological basis, we aimed to assess the incidence of lymphocytic thyroid infiltration (LTI) in our large surgical patient collective over a 31-year period. In our study, a total of 1,050 patients who had undergone uni- or bilateral thyroid surgery for benign goiter were included (150 patients in each group, during 1979 to 2009). The stored histological sections of the removed thyroid specimens were re-analyzed, including routine grading of LTI severity on a scale of 0-4, according to Williams and Doniach. Positive correlations were seen for the incidences of LTI grading (0-4) (r = 0.077, p = 0.013) and HT (r = 0.044, p = 0.078) over the years. Furthermore, when comparing the years 1979-1989 and 1994-2009, i.e., before and after the second iodine prophylaxis had been introduced in Austria, a higher incidence of HT was found for the later years (2 out of 450, 0.4%, vs. 6 out of 600, 1.0%, respectively; p < 0.0001). In conclusion, the data demonstrate that the incidence of LTI and HT has increased substantially over the last 31 years.

    Investigation of effects caused in biological objects by chronic low-intensity radiation in their natural habitats is one of the most important problems of modern radioecology. The aim of our work - complex estimation of state of thyroid gland of voles inhabiting increased radioactive background territories. We investigated tundra voles (Microtus oeconomus Pall.) that were sampled at different stages of population cycle from the experimental and the control sites in the Uhta region of the Komi Republic, Russia. Experimental site contamination resulted from commercial extraction od radium between the 1930's and 1950's. Irradiation exposure dose at the site was 50-2000 mR/h (at the control site 10-15 mR/h). Complex estimation of thyroid was made by histological, morpho-metrical, radioimmunological and cytogenetic methods. Results showed high sensitivity of thyroid gland of tundra voles from chronically irradiated natural populations. We found reliable changes in morphological features of thyroid, in the level of thyroidal hormones and increased frequency of cells with micro-nucleuses in animals sampled from the experimental site as compared with the control ones. It was also showed, that chronic exposure of ionizing irradiation at the same range of absorbed doses can cause different effects in animals depending on sex, age and the stage of population cycle. This confirms the need of including these biological factors to analysis of low doses effects in the natural populations during radioecological studies. Investigations were supported by RFBR grants No. 13-04-01750? and No. 13-04-90351-RBUa. Document available in abstract form only. (authors)

    A prevalent T helper type 1 (Th1) subset of lymphocytes has been described in Hashimoto's thyroiditis (HT), but whether a similar polarization may characterize HT when associated with non-endocrine autoimmune disorders (NEAD) is not known. The aim of the present study was to analyse the intracellular Th1 and Th2 distinctive cytokines in patients with isolated HT or associated with non-endocrine autoimmune disorders. Intracellular cytokine expression was assessed in peripheral blood lymphocytes (PBL) of 68 out-patients (females = 55; males = 13; median age = 6 years) with HT : 33 had isolated HT and 35 had a concurrent NEAD. The percentage of interferon (IFN)-γ and interleukin (IL)-2 Th1- and IL-4 Th2-positive cells was measured by flow cytometric analysis. We found an increased percentage of IL-2-positive cells in all patients, without differences between patients with isolated HT or associated with NEAD. IFN-γ(+) cells were also increased in both groups, but the median percentage of those with isolated HT was lower than in patients with HT+NEAD (19·0 versus 29·9%; P = 0·0082). An increased number of IL-4-positive cells was observed in three of 33 (9·1%) patients with isolated HT and in 25 of 35 patients with NEAD [71%; P lymphocytes characterizes patients with autoimmune thyroiditis who have associated non-endocrine autoimmune disorders. These findings may represent an initial tool to detect patients with autoimmune thyroiditis in which additional non-endocrine autoimmune disorders may be awaited.

    Full Text Available BackgroundSeveral inflammatory biomarkers, especially a high preoperative neutrophil-to-lymphocyte count ratio (NLR and platelet-to-lymphocyte count ratio (PLR, are known to be indicator of poor prognosis in several cancers. However, very few studies have evaluated the significance of the NLR and PLR in papillary thyroid cancer (PTC. We evaluated the association of the preoperative NLR and PLR with clinicopathological characteristics in patients with PTC.MethodsThis study included 1,066 female patients who underwent total thyroidectomy for PTC. Patients were stratified into 4 quartiles by preoperative NLR and PLR. And the combination of preoperative NLR and PLR was calculated on the basis of data obtained value of tertile as follows: patients with both an elevated PLR and an elevated NLR were allocated a score of 2, and patients showing one or neither were allocated a score of 1 or 0, respectively.ResultsThe preoperative NLR and PLR were significantly lower in patients aged ≥45 years and in patients with Hashimoto's thyroiditis. The PLR was significantly higher in patients with tumor size >1 cm (P=0.021.When the patients were categorized into the aforementioned four groups, the group with the higher preoperative PLR was found to have a significantly increased incidence of lateral lymph node metastasis (LNM (P=0.018. However, there are no significant association between the combination of preoperative NLR and PLR and prognostic factors in PTC patients.ConclusionThese results suggest that a preoperative high PLR were significant associated with lateral LNM in female patients with PTC.

    Dogs represent an excellent comparative model for autoimmune thyroiditis as several dog breeds develop canine lymphocytic thyroiditis (CLT), which is clinically similar to Hashimoto's thyroiditis in human. We obtained evidence that dog leukocyte antigen (DLA) class II genotype function as either genetic risk factor that predisposes for CLT or as protective factor against the disease. Genetic diversity at their DLA-DRB1, -DQA1, and -DQB1 loci were defined and potential association to major histocompatibility complex II haplotypes and alleles was analyzed. Giant Schnauzers carrying the DLA-DRB1*01201/DQA1*00101/DQB1*00201 haplotype showed an increased risk (odds ratio of 6.5) for developing CLT. The same risk haplotype has, to date, been observed in three different breeds affected by this disease, Giant Schnauzer, Dobermann, and Labrador Retriever, indicating that it is a common genetic risk factor in a variety of breeds affected by this disease. Importantly, protection for development of the disease was found in dogs carrying the DLA-DRB1*01301/DQA1*00301/DQB1*00501 haplotype (odds ratio of 0.3).

    Polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) are two typical categories of contaminants released from e-waste dismantling environments. In China, the body burdens of PCBs and PBDEs are associated with abnormal thyroid hormones in populations from e-waste dismantling sites, but the results are limited and contradictory. In this study, we measured the serum levels of PCBs and PBDEs and the thyroid hormone free triiodothyronine (FT3), free thyroxine (FT4) and thyroid-stimulating hormone (TSH) in 40 residents in an e-waste dismantling area and in 15 residents in a control area. Additionally, we also measured some lymphocyte proliferation indexes, hematologic parameters and kidney injury markers, including white blood cells, neutrophils, monocytes, lymphocytes, hemoglobin, platelets, serum creatinine and beta 2-microglobulin (β2-MG). The results indicated that the mean level of ΣPCBs in the exposure group was significantly higher than that in the control group (964.39 and 67.98 ng g(-1), p0.05). We determined that serum levels of FT3, FT4, monocytes and lymphocytes were significantly lower, whereas the levels of neutrophils, hemoglobin, platelets and serum creatinine were significantly higher in the exposed group (pe-waste dismantling environment may increase the body burdens of PCBs and the specific PBDEs congeners in native residents and that the contaminants released from e-waste may contribute to abnormal changes in body levels of thyroid hormone, hematology and kidney injury markers.

    The crude herbal formulation, Gamgungtang (GGT), has been shown to protect animals against a wide range of spontaneously developing or induced autoimmune diseases. We have previously reported that GGT shows marked down-regulation of several experimental autoimmune diseases. Although very effective at preventing thyroid infiltrates in mice immunized with mouse deglycosylated thyroglobulin and complete Freund's adjuvant and in spontaneous models of thyroiditis, it completely failed to modify experimental autoimmune thyroiditis (EAT) induced in mice immunized with mouse thyroglobulin and lipopolysaccharide. In this study, in an effort to elucidate the mechanisms by which GGT suppresses EAT, and autoimmunity in general, we investigated the in vivo effects of this drug on the Th1/Th2 lymphocyte balance, which is important for the induction or inhibition of autoreactivity. Naive SJL/J mice were treated orally for 5 days with GGT (80 mg/(kg day)). Spleen cells were obtained at various time points during the treatment period and were stimulated in vitro with concanavalin A. Interleukins IL-4, IL-10 and IL-12, transforming growth factor-beta (TGF-beta) and interferon-gamma (IFN-gamma) cytokine production was evaluated at the protein levels of the cytokines in the medium and mRNA expressions. A significant upregulation of IL-4, IL-10 and TGF-beta was observed following treatment with GGT, which peaked at day 5 (IL-10) or day 10 (IL-4). On the other hand, IL-12 and IFN-gamma production were either unchanged or decreased. It seems therefore that GGT induces in vivo a shift towards Th2 lymphocytes which may be one of the mechanisms of down-regulation of the autoimmune reactivity in EAT. Our observations indicate that down-regulation of TH1 cytokines (especially IL-12) and enhancement of Th2 cytokine production may play an important role in the control of T-cell-mediated autoimmunity. These data may contribute to the design of new immunomodulating treatments for a group of

    Ramsar, a city in the northern Iran, has the highest level of natural background radiation in the world. It has been clearly shown that low doses of ionising radiation can induce resistance to subsequent higher exposures. This phenomenon is termed radioadaptive response. We have compared induction of cytogenetic radioadaptive response by High Natural Background Radiation (HNBR) in Ramsar and X-ray occupational exposure as conditioning doses in human peripheral blood lymphocytes. 30 healthy control individuals, living in Ramsar but in normal background radiation areas, 15 healthy individuals from Talesh Mahalleh, a region with extraordinary high level of background radiation, and 7 X-ray radiographers working in Ramsar hospital located in normal natural background ionising radiation area were evaluated. Peripheral blood samples were prepared and exposed to challenge dose of 0 and 2 Gy. Lymphocytes were scored using analysis of metaphase, for the presence of chromosomal aberrations. An adaptive response was observed in HNBR and radiation workers groups in comparison with sham controls. A significant increase in adaptive response was observed in the HNBR group if compared with the occupationally exposed group. These findings indicate that both natural background radiation and occupational exposure could induce cytogenetic radioadaptive response and it is more significant regarding to natural background ionising radiation.

    The diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC) is a rare tumor with aggressive behavior that requires aggressive treatment. Despite characteristic clinical and histological features that easily permit diagnosis, pre-operative fine-needle aspiration cytology (FNAC) diagnosis is often challenging and thus delays diagnosis. We describe the cytological features of a case of DSV-PTC diagnosed by FNAC in a 30-year-old woman presenting with an ill-defined mass in her neck lasting for 2 months. Ultrasonograpy revealed a heterogeneous enlargement of both thyroid lobes suspicious for a lymphoproliferative syndrome. Flow cytometry showed a suspect B-lymphocyte population. FNAC showed in five out of six slides an overwhelming presence of slightly atypical monomorphic small lymphocytes. The remaining slide showed syncytial tissue fragments of follicular cells with nuclear enlargement and pleomorphism, irregular nuclear membrane, grooves with scattered intranuclear inclusions, squamous metaplastic epithelium, and abundant psammoma bodies. A diagnosis of DSV-PTC was rendered and confirmed by total thyroidectomy and lymph node dissection. Our report supports the possibility of obtaining a preoperative diagnosis of DSV-PTC by FNAC. In the case of diffuse thyroid enlargement, adequate sampling of the thyroid and the presence of the combination of features described in our case permitted the diagnosis of this PTC variant.

    Pernicious anemia is a megaloblastic anemia caused by vitamin B12 deficiency, and is the end-stage of autoimmune gastritis that typically affects persons older than 60 years. It is the most common cause of vitamin B12 deficiency. Pernicious anemia can also be diagnosed concurrently with other autoimmune diseases. We report the occurrence of megaloblastic anemia in a 22-year-old woman with chronic autoimmune thyroiditis for 10.5 years. Recently, she presented with microcytic anemia, and iron deficiency anemia was diagnosed initially. After administration of ferrous sulfate, macrocytic anemia was revealed and vitamin B12 deficiency was detected. Pernicious anemia was highly suspected because of the endoscopic finding of atrophic gastritis, and high titer of antigastric parietal cell antibody, as well as elevated serum gastrin level. After intramuscular injections of hydroxycobalamine 100 microg daily for 10 days, and monthly later, her blood counts returned to normal.

The results indicated that the mean level of ΣPCBs in the exposure group was significantly higher than that in the control group (964.39 and 67.98 ng g{sup −1}, p < 0.0001), but the mean level of ΣPBDEs in the exposure group was not significantly higher than that in the controls (139.32 vs. 75.74 ng g{sup −1}, p > 0.05). We determined that serum levels of FT3, FT4, monocytes and lymphocytes were significantly lower, whereas the levels of neutrophils, hemoglobin, platelets and serum creatinine were significantly higher in the exposed group (p < 0.05). The mean level of ΣPCBs was negatively correlated with levels of FT3, FT4, monocytes and lymphocytes (p < 0.05) and positively correlated with levels of neutrophils, hemoglobin, serum creatinine and β{sub 2}-MG (p < 0.05). Additionally, the mean level of ΣPBDEs was positively correlated with levels of white blood cells, hemoglobin and platelets (p < 0.05). Our data suggest that exposure to an e-waste dismantling environment may increase the body burdens of PCBs and the specific PBDEs congeners in native residents and that the contaminants released

    m6o-color immunophenotyping of lymphocyte subsets using a lysed whole blood method was performed in 46 children and adolescents with Hashimoto`s thyroiditis (HT) from contaminated areas and in 18 children with HT from `pure` areas of Belarus. 46 healthy children of matched age and sex distribution were used as control group. Analysis of lymphocyte subsets in children with HT living in contaminated areas showed a considerable decrease in the levels of total lymphocytes, CD8+T cells (T-suppressors), total B cells, and CD5+B cells together with an activation of NK and CD56+, CD8+CD57+T cells (T-killers not restricted by HLA antigens). The study of cellular immunity in children with different doses of incorporated radionuclids revealed that prolonged influence of very small doses of ionizing radiation resulted in significant changes in lymphocyte subsets; interestingly, B cell subsets were the most sensitive to such influence while radiosensitivity of T-killers and NK was the lowest. These changes were the greatest in children with HT with the highest dose of incorporated radionuclides. Significant correlation between the levels of main lymphocyte subsets and the doses of accumulated radionuclids observed in this study also indicated that their relation was dose-dependent.(orig.)

    Tumor-infiltrating lymphocytes (TILs) are frequently observed in several tumors, reflecting the dynamic process of '"cancer immunoediting"'. Prognostic and predictive values of TILs have been demonstrated in different cancers, proving their pivotal role in clinical outcome. In recent years, new therapies targeting immune checkpoint inhibitors, especially CTLA-4 and PD-1/PDL-1 pathways, have been introduced into clinical practice. In this context, TILs may even have a possible utility as a predictive biomarker for immunotherapy response. Areas covered: In this review, the authors summarize the most relevant knowledge related to TILs. This includes their prognostic and predictive significance in various types of tumour and the recent findings about their potential role in the cancer immunotherapy. Expert opinion: TILs evaluation could lead to a predictive biomarker for immunotherapy effectiveness in several cancer types. Furthermore, typing of TILs subpopulation could have clinical relevance in patient selection for treatment with immune checkpoint inhibitors. However further studies are still needed.

    The association of Hashimoto's thyroiditis and thyroid cancer remains an active focus of research and controversy. Since it was first proposed in 1955, numerous studies have explored the epidemiology and etiology of these concurrent disease processes. The lymphocytic infiltration of Hashimoto's thyroiditis is frequently encountered in thyroid glands resected for a neoplasm. The most frequent association is noted with papillary thyroid cancer. Several recent studies performed on patients undergoing thyroidectomy with coexisting Hashimoto's thyroiditis report an increased prevalence of papillary thyroid cancer, with a favorable disease profile and an improved prognosis, particularly in women. Conversely, some population-based studies using fine-needle aspiration biopsy data report no linkage between serologic Hashimoto's thyroiditis and thyroid cancer, yet they are limited by the lack of definitive pathology. On the other hand, the significantly increased incidence of primary thyroid lymphomas in patients with Hashimoto's thyroiditis strongly suggests a pathogenetic link between this autoimmune disorder and malignant thyroid lymphoma. The lymphocytic infiltration of Hashimoto's thyroiditis is frequently associated with papillary thyroid cancer and may indeed be a risk factor for developing this type of cancer. Nonetheless, a pathogenesis linking these diseases remains unclear. The relationship between thyroid lymphoma and Hashimoto's thyroiditis appears to be well established.

    Perforin plays an essential role in cytotoxicity of natural killers (NK) and CD8+ lymphocytes. Cytotoxicity of T and NK cells is one of the mechanisms of destruction of cells in Hashimoto's disease (HD). The aim of this study was analysis of the expression of perforin in CD8+, CD4+, and NK cells and cytotoxic abilities of these cells in children with HD compared to healthy controls. The expression of perforin and surface antigens, as well as cytotoxicity were analyzed with a flow cytometry. Lower expression of perforin in CD8+ and NK was found in HD compared to controls (p=0.01; p=0.004). A significant correlation between perforin expression in CD8+ lymphocytes and in NK was observed (p=0.05). The spontaneous cytotoxicity of NK was significantly higher in HD compared to controls (p=0.04). Our results suggest that perforin plays an important role in the pathogenesis of autoimmune Hashimoto's thyroiditis.

    A human Fab fragment (SP2) which binds specifically to human thyroid peroxidase has been generated by expressing random combinations of heavy and light chain immunoglobulin genes (derived from Graves' thyroid cDNA) in a bacteriophage lambda library. In common with many serum TPO autoantibodies, the cloned Fab fragment is IgG1 kappa and has a high affinity for TPO (approximately 10(-9) M). On the basis of their nucleotide sequences, the heavy and light chain genes coding for SP2 belong to families VHI, (D), JH3 and VKI, JK2, respectively. These data provide the first characterization at a molecular level of a human thyroid peroxidase antibody associated with autoimmune thyroid disease.

    Full Text Available Background: The course of human immunodeficiency virus infection and the acquired immunodeficiency syndrome can be complicated by a variety of endocrine abnormalities, including abnormalities of thyroid gland. Materials and Methods: This study was designed to understand the spectrum of pathology of thyroid in Indian patients with AIDS. The present study describes the findings of retrospective autopsy findings of 158 patients with AIDS which revealed infectious diseases from a time period before the use of highly active antiretroviral regimen. Results: A wide range of bacterial, fungal, and viral infections were observed. Tuberculosis was recorded in 14 (09% patients, Cryptococcus neoformans in 11 (7% patients and cytomegalovirus in 3 (2% patients. Hashimoto's thyroiditis and lymphocytic thyroiditis were seen in 02 (01% patients each. One patient had dual infection comprising of tuberculosis and cytomegalovirus infection. The other microscopic findings observed were goiter (2 patients, interstitial fibrosis in thyroid (7 patients, and calcification in thyroid (8 patients. Conclusions: Abnormalities of thyroid are uncommon findings in patients with HIV infection however several case reports of thyroid involvement by infectious agents and neoplasm are described in these patients; hence patients with HIV infection should be closely followed up for development of goiter or abnormalities of thyroid functions.

    Papillary thyroid carcinoma (PTC) is the most common type of thyroid neoplasias; however, primary thyroid gland lymphoma (PTL) is uncommon and their simultaneous occurrence is very rare.Herein, we reported a 25-year-old female patient with Hashimoto's thyroiditis (HT), who developed a small goiter with a palpable 1.2-cm nodule in the right lobe. A fine-needle aspiration (FNA) biopsy revealed atypical follicular epithelial cells and lymphoid cells in a background of lymphocytic thyroiditis. A total thyroidectomy was performed. The pathology showed multicentric papillary thyroid carcinoma, concomitant thyroid mucosa-associated lymphoid tissue (MALT) lymphoma, and Hashimoto's thyroiditis. Postoperatively, he received chemotherapy and radioactive iodine ablation treatment. Nowadays the thyroglobulin of the patient is undetectable, without recurrences at 2 years of follow-up.It is concluded that the PTC and MALT lymphoma can exist concomitantly, especially in patients with HT. For the diagnostic workup and optional management of this rare coexistence, a multidisciplinary approach and close surveillance are needed.

    We have studied the functional role of protein kinase Cε (PKCε) in the control of human CD4(+) T cell proliferation and in their response to TGF-1β. We demonstrate that PKCε sustains CD4(+) T cell proliferation triggered in vitro by CD3 stimulation. Transient knockdown of PKCε expression decreases IL-2R chain transcription, and consequently cell surface expression levels of CD25. PKCε silencing in CD4 T cells potentiates the inhibitory effects of TGF-1β, whereas in contrast, the forced expression of PKCε virtually abrogates the inhibitory effects of TGF-1β. Being that PKCε is therefore implicated in the response of CD4 T cells to both CD3-mediated proliferative stimuli and TGF-1β antiproliferative signals, we studied it in Hashimoto thyroiditis (HT), a pathology characterized by abnormal lymphocyte proliferation and activation. When we analyzed CD4 T cells from HT patients, we found a significant increase of PKCε expression, accounting for their enhanced survival, proliferation, and decreased sensitivity to TGF-1β. The increased expression of PKCε in CD4(+) T cells of HT patients, which is described for the first time, to our knowledge, in this article, viewed in the perspective of the physiological role of PKCε in normal Th lymphocytes, adds knowledge to the molecular pathophysiology of HT and creates potentially new pharmacological targets for the therapy of this disease.

    Full Text Available Background/Aim. The major one among the procedures for evaluating changes in the thyroid nodules is fine needle aspiration biopsy (FNAB. Thyroid scintigraphy is commonly used in diagnostic algoritham of nodules. Less than 5% of examined nodules show to be malignant. Scintigraphically, nodules could be classified as functional and nonfunctional. It is estimated that the risk of malignacy in nonfunctional nodules ranges from 8% to 25% and more. Aspiration punction provides 100% specific and positive predictive value. The aim of the study was to establish the distribution of cytological findings in nonfunctioning thyroid nodules. Methods. The prospective study enrolled 112 patients, 104 women and 8 men, submitted to thyroid scintigraphy for known thyroid nodule disorder. Scintigraphy was performed about half an hour after iv administration of 74 MBq of sodium-pertehnetate. A pin hole collimator was used. Scintigrams were visually evaluated, and absence of radiopharmaceutic in a nodule was estimated as nonfunctional one. Such nodules were afterwards subjected to FNAB and material obtained was cytologically analyzed. Results. In our patients nonfunctioning nodules comprised tissue of colloid struma, thyroid cyst, regular thyroid tissue, follicular lesion, oxiphillic lesion, papillary carcinoma tissue and tissue of lymphocytic thyroiditis. The most frequent cytological finding were colloid cysts (52%. A total of 70% were female nodules. Five citological findings were histopathologically analyzed. Conclusion. Cytological finding of nonfunctional nodules determines of the decision on radical therapy, and our preliminary results imply the need of FNAB routine use in nuclear medicine practice.

    Full Text Available Abstract Background Lithium is an integral drug used in the management of acute mania, unipolar and bipolar depression and prophylaxis of bipolar disorders. Thyroid abnormalities associated with treatment with lithium have been widely reported in medical literature to date. These include goitre, hypothyroidism, hyperthyroidism and autoimmune thyroiditis. This current review explores the varied thyroid abnormalities frequently encountered among patients on lithium therapy and their management, since lithium is still a fundamental and widely drug used in psychiatry and Internal Medicine. Methods PubMed database and Google scholar were used to search for relevant English language articles relating to lithium therapy and thyroid abnormalities up to December 2012. The search terms used were lithium treatment, thyroid abnormalities, thyroid dysfunction, goitre, hypothyroidism, hyperthyroidism, thyrotoxicosis, autoimmune thyroiditis, lithium toxicity, treatment of affective disorders and depression and side effects of antipsychotic drugs. Reference lists of the identified articles were further used to identify other studies. Results Lithium affects normal thyroid functioning through multiple mechanisms. At the cellular level, it decreases thyroid hormone synthesis and release. It also decreases peripheral deiodination of tetraiodothyronine (T4 or thyroxine by decreasing the activity of type I 5’ de-iodinase enzyme. Hypothyroidism and goitre (clinically and/ultrasonographically detected are the most prevalent thyroid abnormalities among patients on long term lithium therapy. Lithium induced hyperthyroidism is very infrequent. Lithium increases the propensity to thyroid autoimmunity in susceptible individuals due to its effect of augmenting the activity of B lymphocytes and reducing the ratio of circulating suppressor to cytotoxic T cells. Conclusions Thyroid function tests (serum thyroid stimulating hormone, free thyroid hormones-T4 and

    Radioiodine therapy of benign thyroid diseases (focal = [toxic adenoma], multifocal, disseminated autonomy, Grave's disease or clinical relevant goitre) needs to be and can be performed individually for each patient. Most frequently a radioiodine test is performed applying a small activity of iodine-131 ({sup 131}I). The paper discusses some protocols for pre- or posttherapeutic dosimetry and discusses their advantages and disadvantages. All are based on the volumetry of the target tissue as well as the radioiodine kinetics in the target volume what may be represented by maximum uptake and half life of iodine retention in the thyroid. Possible disturbances and measuring uncertainties of these parameters are presented and discussed. In spite of the discussed uncertainties in dosimetry, due to its high therapeutic width radioiodine therapy is a very successful procedure to cure hyperthyroidism or to reduce goitre volume with only little side effects.

    Full Text Available Background Papillary thyroid cancer (PTC is mainly diagnosed using fine-needle aspiration biopsy. This most common form of well-differentiated thyroid cancer occurs with or without a background of benign thyroid goiter (BTG. Methods In the present study, a gel-based proteomics analysis was performed to analyse the expression of proteins in tissue and serum samples of PTC patients with (PTCb; n = 6 and without a history of BTG (PTCa; n = 8 relative to patients with BTG (n = 20. This was followed by confirmation of the levels of proteins which showed significant altered abundances of more than two-fold difference (p < 0.01 in the tissue and serum samples of the same subjects using ELISA. Results The data of our study showed that PTCa and PTCb distinguish themselves from BTG in the types of tissue and serum proteins of altered abundance. While higher levels of alpha-1 antitrypsin (A1AT and heat shock 70 kDa protein were associated with PTCa, lower levels of A1AT, protein disulfide isomerase and ubiquitin-conjugating enzyme E2 N seemed apparent in the PTCb. In case of the serum proteins, higher abundances of A1AT and alpha 1-beta glycoprotein were detected in PTCa, while PTCb was associated with enhanced apolipoprotein A-IV and alpha 2-HS glycoprotein (AHSG. The different altered expression of tissue and serum A1AT as well as serum AHSG between PTCa and PTCb patients were also validated by ELISA. Discussion The distinctive altered abundances of the tissue and serum proteins form preliminary indications that PTCa and PTCb are two distinct cancers of the thyroid that are etiologically and mechanistically different although it is currently not possible to rule out that they may also be due other reasons such as the different stages of the malignant disease. These proteins stand to have a potential use as tissue or serum biomarkers to discriminate the three different thyroid neoplasms although this requires further validation in clinically

    Full Text Available Background: Intrathyroid lymphoid tissue is accrued in Hashimoto thyroiditis (HT. Histologically, this acquired lymphoid tissue bears a close resemblance to mucosa-associated lymphoid tissue (MALT and can evolve to lymphoma. Aim: To demonstrate the morphological, and immunohistochemical profiles of Hashimoto thyroiditis and to ascertain the importance of light chain restriction in distinguishing HT with extensive lymphoplasmacytoid infiltrate from MALT lymphoma. Materials and Methods: We studied histopathologically and immunohistochemically (CD20, CD3, Igk, Igl and cytokeratin 30 cases of HT for evaluation of the lymphoid infiltrate and the presence of lymphoepithelial lesions (LELs. Distinguishing between early thyroid lymphoma and HT was evaluated by light chain restriction. These findings were compared with two cases of primary thyroid lymphoma. Results: The histopathological findings were characteristic of HT. Immunohistochemistry confirmed inconspicuous, rare B-cell LELs as well as a prominent T-lymphocyte population. Testing for light chain restriction showed polyclonal population of plasma cells. The cases of MALT lymphoma had distinct destructive lymphoepithelial lesions, B-cell immunophenotyping and showed kappa light chain restriction in the plasmacytoid population. Conclusions: Hashimoto thyroiditis differs both histopathologically and immunohistochemically from thyroid lymphoma. In suspicious cases, immunohistochemistry could be helpful in reaching a definitive diagnosis.

    Autoimmune thyroid disease (AITD), including Graves disease (GD) and Hashimoto disease (HD), is an organ-specific autoimmune disease with a strong genetic component. Although the cytotoxic T-lymphocyte-associated protein 4 (CTLA4) polymorphism has been reported to be associated with AITD in adults, few studies have focused on children. The aim of our study was to investigate whether the CTLA4 polymorphisms, including -318C/T (rs5742909), +49A/G (rs231775), and CT60 (rs3087243), were associated with GD and HD in Han Chinese adults and children. We studied 289 adult GD, 265 pediatric GD, 229 pediatric HD patients, and 1058 healthy controls and then compared genotype, allele, carrier, and haplotype frequencies between patients and controls. We found that CTLA4 SNPs +49A/G and CT60 were associated with GD in adults and children. Allele G of +49A/G was significantly associated with GD in adults (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.21–1.84; corrected P value [Pc] < 0.001) and children (OR, 1.42; 95% CI, 1.15–1.77; Pc = 0.002). Allele G of CT60 also significantly increased risk of GD in adults (OR, 1.63; 95% CI, 1.27–2.09; Pc < 0.001) and GD in children (OR, 1.58; 95% CI, 1.22–2.04; Pc < 0.001). Significant linkage disequilibrium was found between +49A/G and CT60 in GD and control subjects (D’ = 0.92). Our results showed that CTLA4 was associated with both GD and HD and played an equivalent role in both adult and pediatric GD in Han Chinese population. PMID:27111218

    Guidelines on the management of thyroid dysfunction during pregnancy have recently been updated and, for the diagnosis of subclinical hypothyroidism (SCH), a thyroid-stimulating hormone (TSH) upper reference limit (cut-off) of 4.0 mIU/L has been proposed when no institutional values are available. It is also suggested that serum TSH and thyroid autoimmunity (TAI) may be different according to the ethnic background of the women. We therefore determined the prevalence of TAI and SCH in pregnant women with different ethnic backgrounds and, to define SCH, we used different first trimester TSH upper reference cut-offs (institutional, ethnicity-specific, 2.5 mIU/L [Endocrine Society] and 4.0 mIU/L [American Thyroid Association]). Cross-sectional data analysis of 1683 pregnant women nested within an ongoing prospective database of pregnant women. The study was performed in a single centre in Brussels, Belgium. During the first antenatal visit, thyroid peroxidase antibodies (TPO-abs), TSH and free T4 (FT4) were measured and baseline characteristics recorded. Data from 481 women with sub-Saharan (SaBg; 28.6%), 754 North African (NaBg; 44.8%) and 448 Caucasian (CaBg; 26.6%) backgrounds were analysed. For the calculation of TSH reference ranges, women with TAI, outliers, twin and assisted pregnancies were excluded. The prevalence of TAI was significantly lower in the SaBg group than in NaBg and CaBg groups (3.3% vs 8.6% and 11.1%; Pwomen with SCH was comparable between all groups when 2.5 mIU/L was used as cut-off, but when 4.0 mIU/L or the institutional cut-off (3.74 mIU/L) was used, it was significantly higher in the CaBg group vs the NaBg group (5.4% vs 2.1% and 7.1% vs 3.3%, P=.008 and .013, respectively). The use of ethnicity-specific cut-offs did not change the prevalence of SCH as compared to the use of institutional cut-offs. However, when these cut-offs were used, the prevalence of SCH reduced by >70% (4.5% instead of 16.7%; PPregnant women with a sub

    The hot springs in certain areas of Ramsar contain (226)Ra and (222)Rn. The effects of natural radiation on the inhabitants of these areas and the inhabitant's radiosensitivity or adaptive responses were studied. One group of volunteers from areas with high natural background radiation and another group from areas with normal background radiation were chosen as the case and control group respectively. The frequency of micronuclei, apoptosis, and DNA damage in peripheral blood mononuclear cells were measured following gamma irradiation (4 Gy). The incidence of micronuclei in the case group was significantly lower than that in the control group while their frequency of apoptosis was higher (P sites, the individuals in the case group are more sensitive and susceptible to DNA damage. The results of micronuclei, apoptosis and repair studies suggest that an adaptive response might be induced in people residing in areas with high background radiation.

    Full Text Available Abstract Background Hashimoto Thyroiditis (H.T. is a destructive autoimmune thyroid condition whose precise molecular pathogenesis remains unclear. ret/PTC-1 is a chimeric transcript which has been described in autoimmune thyroid disease (AITD and thyroid neoplasia. The purpose of this study was to observe the immunogenic effect exposure to H.T. and control lymphocyte supernatant would have on normal (Nthy-ori and ret/PTC-1 (TPC-1 expressing thyroid cell line models. Results A 2 × 2 matrix comprising Nthy-ori and TPC-1 cell lines and H.T. and control lymphocyte supernatant was designed and utilised as follows; activated lymphocytic supernatant from a H.T. and normal control were co-cultured with a cell line derived from normal thyroid (Nthy-ori and also a cell line derived from a papillary thyroid carcinoma that endogenously expresses ret/PTC-1 (TPC-1. The co-cultures were harvested at 0, 6 and 18 hour time points. Gene expression analysis was performed on RNA extracted from thyrocytes using TaqMan® Immune profiling Low-Density Arrays (Applied Biosystems, CA, USA comprising gene expression markers for 93 immune related targets plus 3 endogenous controls. Stimulation of the normal thyroid cell line model with activated T cell supernatant from the H.T. donor yielded global up-regulation of immune targets when compared with control supernatant stimulation. In particular, a cohort of targets (granzyme B, CD3, CD25, CD152, CD45 associated with cytotoxic cell death; T cell receptor (TCR and T cell signaling were up-regulated in the normal cell line model. When the ret/PTC-1 expressing thyroid cell line was co-cultured with H.T. lymphocyte supernatant, in comparison to control supernatant stimulation, down-regulation of the same subset of immune targets was seen. Conclusion Co-culturing H.T. lymphocyte supernatant with a normal thyroid cell line model leads to over-expression of a subset of targets which could contribute to the pathogenesis of H

    Full Text Available BACKGROUND: Hashimoto thyroiditis is the most common form of thyroiditis. The incidence is found more in the coastal areas for which iodine excess is described as a probable etiology .Ours is a coastal area, where significant number of females is coming to the hospital with diffuse enlargement of thyroid. This prompted us to do the current study. FNAC is a simple, cost effective, diagnostic modality which when used in combination with sonological and serological investigations, helps the clinicians in the correct diagnosis, even in the early stage of the disease. MATERIALS AND METHODS: Retrospective study was done for a period of 18 months from January1rst 2013 to JUNE 31rst 2014. The clinical, sonological and serological aspects of 80 cases of Hashimoto's thyroiditis were studied and compared with the cytomorphological features. RESULTS: The peak incidence of Hashimoto’s thyroiditis was seen in women of 2nd decade. Coexisting colloid goiter was noted in significant number of cases. Subclinical thyroid and euthyroid cases (serologically showed cytomorphological features diagnostic of thyroiditis. Correlation with sonological features were seen in 66 % of cases. Lymphocytic infiltrate in follicular cell clusters, background lymphocytes and plasma cells and hurthle cells were diagnostic of hashimoto's thyroiditis. CONCLUSION: The increased frequency of Hashimoto’s thyroiditis in younger age group, in euthyroid cases and its coexistence with colloid goiter should prompt us to take more detailed and large scale study in Kerala, especially in the coastal areas. FNA should be done as a first line mode of investigation, since it helps in identifying Hashimoto thyroiditis in the initial stages when the serological findings may be normal.

    Full Text Available Abstract Background Papillary thyroid carcinoma (PTC and medullary thyroid carcinoma (MTC have always been considered different from each other; in their incidence, their cell origin and their histopathological features. Case presentation This paper describes two rare cases of the simultaneous occurrence of MTC and PTC in the thyroid gland. Case 1 is unique for different reasons: (a the patient was affected by both multicentric MTC and PTC; (b a "composite thyroid carcinoma" with mixed feautures of MTC and PTC carcinomas was found in the istmus of the gland; and (c these tumors were associated with diffuse lymphocytic-type thyroiditis (LT. Case 2 is notable for the long follow up: 16 years disease free. Conclusion There are only 16 reports in the English medical literature describing a total of 20 cases of concurrent occurrence of both PTC and MTC in the same thyroid gland. We discuss whether the finding of another cancer in these patients was coincidental or from possible activation of a common tumorigenic pathway for both follicular and parafollicular thyroid cells.

    Full Text Available Abstract Background Immunohistochemical methods based on the high affinity of avidin and biotin (e.g. ABC, LSAB are characterized by high sensitivity and are widely used for detection of immunologic reaction. However, a non-specific reaction, observed in frozen tissues and in paraffin-embedded material, increasing after heat induced epitope retrieval (HIER, and caused either by endogenous biotin or any another chemical compound with high affinity for avidin, may lead to diagnostic mistakes. The aim of our investigation is to study presence of endogenous avidin biotin activity (EABA in thyrocytes originating from various thyroid pathological lesions (neoplastic and non-neoplastic. Materials and methods The immunohistochemical study was performed on paraffin-embedded specimens of surgically resected thyroid tissue from 97 patients with thyroid diseases: 65 patients with papillary carcinoma (PTC, 11 patients with nodular goiter in whom features of benign papillary hyperplasia were found, 9 with lymphocytic thyroiditis (LT, 8 with follicular adenoma, and 4 patients with follicular carcinoma. In PTC immunohistochemical study was performed both in primary tumors and in lymph node metastases. After HIER, incubation with streptavidin from LSAB+ (DakoCytomation kit was done. Results Strong cytoplasmic EABA was observed in 56 of 65 (87.5% PTC and in oxyphilic cells in 8 of 9 cases of LT. Significant correlation between EABA in primary PTC tumor and EABA in lymph node metastases was stated. Normal surrounding thyroid tissues showed absence or weak EABA. Aberrant intranuclear localization of biotin was noted in morules of cribriform-morular variant of PTC. No statistically significant correlation between patient's age, sex, metastases presence and EABA was observed. Conclusion Among thyroid lesions, false positive reactions are highly probable in papillary thyroid carcinoma and in lymphocytic thyroiditis if immunohistochemical detection is used on systems

    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.

    Full Text Available BACKGROUND Diverse cytological patterns of thyroid lesions may occur in the thyroid gland for its various diseases. The thyroid lesions may be nonneoplastic lesions or neoplastic lesions. Most of the thyroid lesions clinically present as thyroid swellings either as thyroid nodules or as diffuse enlargement of the gland itself. Fine Needle Aspiration Cytology (FNAC is a rapid, easy to perform, minimally invasive and cost-effective first line high diagnostic accuracy test for cytological evaluation of thyroid lesions with minimum complications. The thyroid gland is easily accessible for Fine Needle Aspiration (FNA procedure due to its superficial location. The accurate cytological diagnosis of the thyroid lesions can direct the treatment modalities of the lesions and reduce unnecessary thyroid surgeries. AIMS AND OBJECTIVES A hospital-based study to determine the cytological patterns of thyroid lesions by FNAC and to correlate the cytological and histopathological diagnosis wherever possible. MATERIALS AND METHODS The study was based on “FNAC analysis of 100 thyroid lesions presented as thyroid swellings” (study group in the period of two (02 years from June 1, 2014, to May 31, 2016, in the cytopathology section of the Pathology Department of Tezpur Medical College and Hospital, Tezpur, Assam. Histopathological correlation was done in the surgically treated thyroid lesions of the study group. RESULTS AND OBSERVATIONS Female patients (87 comprised majority of thyroid lesions (87.00%, while male patients (13 were only 13.00% of thyroid lesions with a male and female patients’ ratio of 6.69:1 in the study group. Maximum patients with thyroid lesions, irrespective of sex in the study group were in the age group of 31-40 years. The youngest patient in the study group was a 7 years old girl diagnosed as lymphocytic thyroiditis and the oldest patient in the study group was a 73 years old female diagnosed as colloid goitre.

    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

    Sclerosing mucoepidermoid carcinoma with eosinophilia (SMECE) was first described by Chan et al in 1991. It is characterized by nest or strands of epidermoid tumor cells with squamous differentiation, rare mucous cells, prominent sclerotic stroma, eosinophilic and lymphoplasmacytic infiltration, and a background of chronic lymphocytic thyroiditis in the non-neoplastic thyroid gland. It is important to recognize SMECE of thyroid and differentiate it from squamous cell carcinoma or other neoplasms with squamous differentiation/metaplasia. In published cases, the SMECE of thyroid gland predominantly occurs in women. We report a case of SMECE of thyroid in a 45-year-old male patient. All cases in male patients were Caucasian described in English literature, and our case is the first one in Asian.

    Full Text Available Malignant tumors of the thyroid gland account for about 1% of thenewly diagnosed malignant tumors each year, and their incidence inwomen is twice the incidence in men. According to the WHO classification (2004 thyroid tumors are divided into: carcinoma of the thyroid, adenoma and similar tumors, and other thyroid tumors which include: teratomas, angiosarcomas, paragangliomas and others, as well as primary lymphomas and plasmacytomas. Primary thyroid lymphomasare defined as lymphomas which originate in the thyroid gland. This study presents the case of a 68-year-old patient with a thyroid lymphoma, which caused compression of the airways. In the patientpresented there was reduced activity of the thyroid gland. The dominant symptoms were: breathing difficulties, hoarse voice and the enlargement of the thyroid. An ultrasound examination was performedbefore surgery on the neck, which showed a multinodular thyroid,with compromised and compressed trachea to the right and rear. Anemergency surgical procedure was performed to reduce the tumor.Pathohistological diagnosis confirmed diffuse large B cell lymphoma.The aim of the study was to present a patient with a thyroid lymphoma, who had previously not had any immunological changes to the gland,that is, she had not had any chronic lymphocyte thyroiditis, but due to the compressive syndrome it was necessary to perform an emergencysurgical procedure to reduce the tumor.

    Evidence suggests that in most industrialized countries autoimmune disorders, including chronic lymphocytic thyroiditis, are increasing. This increase parallels the one regarding differentiated thyroid cancer, the increment of which is mainly due to the papillary histotype. A number of studies have pointed to an association between chronic lymphocytic thyroiditis and differentiated thyroid cancer. The upward trend of these two thyroid diseases is sustained by certain environmental factors, such as polluting substances acting as endocrine disrupting chemicals. Herein we will review the experimental and clinical literature that highlights the effects of environmental and occupational exposure to polluting chemicals in the development of autoimmune thyroid disease or differentiated thyroid cancer. Stakeholders, starting from policymarkers, should become more sensitive to the consequences for the thyroid resulting from exposure to EDC. Indeed, the economic burden resulting from such consequences has not been quantified thus far.

    Full Text Available Primary thyroid lymphomas are rare neoplasms comprising of 1-5% of thyroid malignancies. These are predominantly B-cell in origin. Here, we report a case of 60 years lady, a known case of lymphocytic thyroiditis, diagnosed as thyroid lymphoma (diffuse large B-cell on fine needle aspiration and confirmed histopathogically and immunohistochemically. She presented with a sudden increase in thyroid swelling. Fine needle aspiration performed showed highly cellular smears comprising predominantly of the monomorphic population of medium to large sized lymphoid cells with high nuclear/cytoplasmic ratio and scant cytoplasm. A possibility of thyroid lymphoma possibly diffuse large B-cell lymphoma was suggested which was later confirmed on biopsy. Fine needle aspiration provides an easy mode for diagnosing large cell lymphoma like diffuse large B-cell. Hence, an early diagnosis is possible for a timely intervention. Also, cases of lymphocytic thyroiditis should be regularly followed for the development of lymphoma.

    Full Text Available Introduction. Primary thyroid lymphomas constitute up to 5% of all thyroid malignancies and can be divided into non-Hodgkin’s lymphomas (NHLs of B- and T-cell types, as well as Hodgkin’s lymphomas. Mucosa-associated lymphoid tissue (MALT lymphomas are a relatively recently recognized subset of B-cell NHLs, and they are listed as extranodal marginal zone lymphomas according to the revised European-American lymphoma classification. Case Report. We report an uncommon case of a 44-year-old man, who noted a painless, growing mass on right side of his neck of the three-month duration. Thyroid profile was within normal limits. FNAC showed lymphocytic thyroiditis. The patient underwent a right hemithyroidectomy. The histologic examination and the immunohistochemistry showed an extra nodal marginal B-cell type maltoma (malt lymphoma. CHOP chemotherapy with rituximab was given. The clinical course has been favourable in the first year of followup, with no evidence of local or systemic recurrence of the disease. Discussion. Marginal zone lymphoma encompasses a heterogeneous group of B-cell tumours that variously arise within the lymph nodes, spleen, or extranodal tissues. A case of maltoma of thyroid is presented for its rarity and diagnostic dilemmas. Conclusion. Maltomas are slow-growing lymphomas. The optimal treatment and followup of patients with thyroid maltomas remain controversial at present.

    Hashimoto's thyroiditis is the most common diffuse thyroid disease and is characterized by diffuse lymphocytic infiltration. However, the ultrasonographic findings of papillary thyroid carcinomas that arise from Hashimoto's thyroiditis in the pediatric and adolescent population are not well known.We report a rare ultrasonographic finding in a 22-year-old woman diagnosed with the diffuse sclerosing variant of papillary thyroid carcinoma that arose from underlying Hashimoto's thyroiditis: innumerable diffuse microcalcifications instead of a typical malignant-appearing nodule.

    Full Text Available Cooccurrences of chronic lymphocytic thyroiditis (CLT and thyroid cancer (DTC have been repeatedly reported. Both CLT and DTC, mainly papillary thyroid carcinoma (PTC, share some epidemiological and molecular features. In fact, thyroid lymphocytic inflammatory reaction has been observed in association with PTC at variable frequency, although the precise relationship between the two diseases is still debated. It also remains a matter of debate whether the association with a CLT or even an autoimmune disorder could influence the prognosis of PTC. A better understanding about clinical implications of autoimmunity in concurrent thyroid cancer could raise new insights of thyroid cancer immunotherapy. In addition, elucidating the molecular mechanisms involved in autoimmune disease and concurrent cancer allowed us to identify new therapeutic strategies against thyroid cancer. The objective of this article was to review recent literature on the association of these disorders and its potential significance.

    Objective To analyze the distribution of T lymphocyte subsets in tumor microenvironment of papillary thyroid carcinoma (PTC). Methods The levels of CD3+ CD4+ CD8- ,CD3+ CD4- CD8+ ,CD3+ CD4+ CD8+ ,CD3+ CD4- CD8- T cell and CD4+/CD8+ ra- tio in tumor microenvironment of 35 cases PTC, 25 cases benign thyroid lesion and 15 healthy eases were detected by flow cytometry. Results Local tumor tissue of 35 cases PTC and 25 cases benign thyroid lesion, and blood of 15 healthy cases were collected. The ratio of CD4+/ CD8+ in blood, tumor microenvironment of benign thyroid lesions and PTCs decreased significantly ( P0.05). The levels of CD3+ CD4- CD8- cell in tumor microenvironment of benign thyroid lesion were higher than those in PTC and peripheral blood(P0.05 ). The differences of CD4+/CD8+ ratio and the level of each of T lymphocyte subset such as CD3+ CD4+ CD8-, CD3+ CD4- CD8+, CD3+ CD4+ CD8+, CD3+ CD4- CD8- cell between 15 PTC cases with lymph node metastasis and 20 PTC cases without metastasis were not significant (P>0.05). Conclusions CD8+ T cell is the main immune cell in tumor microenvironment in PTC. The local cell-mediated immunity of PTC is in the status of obviously suppressed. But the obvious increase of CD3+ CD4+ CD8+ and CD3+ CD4- CD8- T cells in tumor microenvironment in thyroid benign lesion may be beneficial for creating the location for immune responding against tumor.

    Ayça ERŞEN

    2013-01-01

    Full Text Available Warthin-like tumor of the thyroid is a recently described rare variant of thyroid papillary carcinoma. The distinguishing histological feature of this variant is papillary foldings lined by oncocytic neoplastic cells with clear nuclei and nuclear pseudoinclusions, accompanied by prominent lymphocytic infiltrate in the papillary stalks. Its prognosis has been reported to be almost similar to conventional papillary carcinoma. In this case series, we report four cases with Warthin-like papillary carcinoma of the thyroid, diagnosed at Dokuz Eylul University Faculty of Medicine Department of Pathology in 2008 and 2009. Three patients were female. The mean patient age was 39 years (range, 20-56 and the mean tumor size was 1.7 cm (range, 0.9-2.0 cm. All of the cases had lymphocytic thyroiditis in the background. None of the tumors showed lymphovascular invasion. The patients are free of any recurrence and/or distant metastasis with a mean follow-up of 25 months. This rare variant of thyroid papillary carcinoma with distinct histopathological features should be indicated in pathology reports. Further studies and long-term follow-up of patients are needed to highlight the biological behavior of this variant.

    2014-01-01

    Full Text Available Background: Hashimoto′s thyroiditis (HT is an autoimmune disease and it is more prevalent in Asians. The incidence of HT seems to be increasing in the recent times. It is one of the most common cause of hypothyroidism. The purpose of this study is to review the cytomorphologic spectrum of HT and correlate it with clinical findings including thyroid function and antibody profile. Materials and Methods: We retrospectively analyzed the fine-needle aspiration (FNA features of 52 HT patients. Based on cytomorphologic features patients were categorized into three groups. Clinical findings including thyroid function and thyroid peroxidase (TPO antibody profile were correlated with cytomorphologic features in all three groups. Results: Majority of the patients were females and in 2 nd , 3 rd and 4 th decades. Diffuse goiter and thyroid hypofunction were the common findings. Significant number of patients had thyroid hyperfunction. Increased lymphocytes on the background and lymphocytic infiltration of thyroid follicular cell clusters in cytology smears were diagnostic of HT. The 32 patients showed elevated titers of TPO antibodies. In the early stages and mild form of the disease, results of thyroid function and anti TPO antibodies are quite variable. Conclusions: HT is a disease of young and middle age and mostly occur in females. Clinical findings alone may not be adequate for definitive diagnosis. FNA is the gold standard for diagnosis. In the presence of abundant colloid, follicular hyperplasia or co-existing neoplasm, careful interpretation of cytology smears should be done. Aspiration from more than one site minimizes the diagnostic pitfalls.

  7. PREGNANCY AND THYROID

    Directory of Open Access Journals (Sweden)

    2004-01-01

    Full Text Available Background. In conditions with appropriate iodine intake, thyroid gland adapts to changes during pregnancy without any consequences. Fetal need for thyroid hormones in the first trimester is directly connected with transplacental transport of thyroid hormones. Fetal synthesis of thyroid hormones depends on availability of iodine in the feto-placental unit. Hypo- and hyperthyroidism during pregnancy are risk factors for pregnant woman and for normal development of fetus and child.Conclusions. Pregnant women with appropriately treated thyroid diseases have the same outcome of pregnancy as healthy women, and neuroendocrinological development of children is not impaired. If the disease is unrecognized or untreated, complications of pregnancy and delivery occur more frequently. Therefore, timely recognition and treatment of the diseases with appropriate drugs during pregnancy and, also, after delivery is very important.

    Background & objectives: Despite, the extensive salt iodization programmes implemented in India, the prevalence of goiter has not reduced much in our country. The most frequent cause of hypothyroidism and goiter in iodine sufficient areas is Hashimoto's thyroiditis (HT). This study records the clinical presentation, biochemical status, ultrasonographic picture and cytological appearance of this disease in a coastal endemic zone for goiter. Methods: Case records of patients with cytological diagnosis of HT were studied in detail, with reference to their symptoms, presence of goiter, thyroid function status, antibody levels and ultrasound picture. Detailed cytological study was conducted in selected patients. Results: A total of 144 patients with cytological proven HT/lymphocytic thyroiditis were studied. Ninety per cent of the patients were females and most of them presented within five years of onset of symptoms. Sixty eight per cent patients had diffuse goiter, 69 per cent were clinically euthyroid and 46 per cent were biochemically mildly hypothyroid. Antibody levels were elevated in 92.3 per cent cases. In majority of patients the sonographic picture showed heterogeneous echotexture with increased vascularity. Cytological changes were characteristic. Interpretation & conclusions: Our study showed predominance of females in the study population in 21-40 yr age group with diffuse goiter. We suggest that in an endemic zone for goiter, all women of the child bearing age should be screened for HT. PMID:25758571

    Palpable thyroid nodules are present in 4-7% of general population and Fine Needle Aspiration (FNA) is now accepted by endocrinologists and thyroid surgeons as a safe, simple and cost effective procedure for evaluating a thyroid nodule. The obtained sample can be spread directly on slides, processed as cell block preparations or prepared as liquid base smears. Liquid base method has been recently accepted due to its shorter preparation time and better preservation of nuclear details. The aim of this study is to compare the diagnostic results of two commonly used methods: Liquid Base Preparation and Cell Block Preparation in evaluation of thyroid nodules. The samples were taken from 100 patients with a solitary nodule or a prominent nodule on a multinodular goiter background (excluding hot nodules). The obtained samples were used to prepare conventional smears (CS), Cell Block Preparations (CBP) and Liquid Base Preparations (LBP). The slides were studied by two pathologists, considering the following parameters: Cellularity, Colloid, Lymphocytes/Plasma cells and Macrophages. 87% of cases revealed informative results in LBP method while in the same group of patients only 69% of samples were informative after processing by CBP method. Sensitivity and specificity of both methods compared with the conventional smears and with each other and it is concluded that LBP is a reliable method for evaluating of a thyroid nodule. Other studies also show the same results. The liquid base method should be trusted due to its easier procedure, cleaner slide background, its higher specificity and higher diagnostic yields. It can be used instead of CBP and in association with CS to increase the accuracy of evaluation of thyroid nodules.

    Among 4325 goiter patients first examined in the period from February 1980 to April 1982, 5 cases of lymphoma appearing primarily in the thyroid gland were discovered incidentally. During the same period 13 patients with anaplastic thyroid carcinoma were observed. 5 of 23 systematically examined patients who had already known extrahyroidal malignant non-Hodgkin's lymphomas and lymphoma patient examined by chance exhibited a secondary thyroid gland lymphoma, that is, a secondary infiltration of the enlarged thyroid. Altogether, 29 patients with malignant non-Hodgkin's lymphoma (Kiel classification) were examined. Of 8 Hodgkin's disease patients none showed clinical or cytological evidence of thyroid infiltration. The clinical symptoms of primary lymphoma of the thyroid gland corresponded to those of anaplastic thyroid carcinoma. A positive differential diagnosis of the two tumours succeeded cytologically. The secondary lymphoma of the thyroid also could only be diagnosed cytologically. Patients with Hodgkin's lymphoma and non-Hodgkin's lymphoma were always found to be euthyroid. Autoimmunological phenomena (antimicrosomal and antithyreoglobulin autoantibodies) as an indicator of lymphocytic thyroiditis could only be examined among 11 patients. Two patients with secondary lymphoma of the thyroid showed positive titers. A small cell anaplastic thyroid carcinoma could not be diagnosed in any of 37 patients with anaplastic thyroid cancer out of an enlarged patient collective (period under consideration: 1976-1982).

    Full Text Available Background: Fine needle aspiration has an important role in diagnosis of thyroid neoplasm. However, it is difficult to differentiate between follicular adenoma and follicular carcinoma by cytology alone. Recently, silver staining has been performed for nucleolar organizer regions (AgNORs to differentiate various tumors. Aims: The present study was undertaken to see if the AgNOR technique could distinguish between benign and malignant lesions, particularly, follicular neoplasm. Materials and Methods: One hundred forty cases of thyroid lesions were examined, which included colloid goiter (n = 36, multinodular goiter (n = 38, subacute thyroiditis (n = 6, Hashimoto′s thyroiditis (n = 17, lymphocytic thyroiditis (n = 3, follicular neoplasm (n = 18, Hurthle cell neoplasm (n = 3, papillary carcinoma (n = 16, and medullary carcinoma (n = 3. Diagnosis was confirmed by histopathology in 80 cases. The usual one-step silver colloidal reaction was performed at room temperature for 35 minutes and intranuclear dots of silver deposits were counted in 100 cells. Results: AgNOR counts of benign and malignant lesions were compared and were found to be statistically significant (P < 0.001. The mean AgNOR counts were higher in neoplastic lesions. Conclusions: AgNOR counting in fine needle aspiration smears is a simple, sensitive, and cost-effective method for differentiating benign from malignant thyroid follicular neoplasms.

    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.

    Diffuse sclerosing papillary thyroid carcinoma (DSPTC) is a relatively rare variant of papillary thyroid carcinoma with distinct histological features, radiological characteristics, and biological aggressiveness. Compared with conventional papillary thyroid carcinoma, DSPTC is characterized by scattered microscopic tumor islands, diffuse fibrosis, calcification, and abundant lymphocytic aggregation. A preoperative diagnosis is challenging in the absence of nodules and scanty fine needle aspiration cytology samples. We describe a unique DSPTC patient, an 18-year-old woman who presented with a neck mass that grew slowly for 2 years. The palpable neck mass was nontender, well defined, firm, and unmovable. Laboratory studies showed normal thyroid function and positive autoimmune markers: antithyroglobulin antibody = 1:1600 and antimicrosomal antibody = 1:1600. A neck ultrasound showed diffusely prominent microcalcifications with one small vague nodule. Hashimoto's thyroiditis with an accompanying malignancy was suspected. Based on the result of intraoperative pathology reports, the patient was given a total thyroidectomy. Lymph node dissection and histological analysis revealed bilateral DSPTC in addition to lymphocytic thyroiditis in nonmalignant areas of the thyroid. Clinical and histological diagnostic challenges usually occur when DSPTC presents with a diffuse thyroid enlargement, dispersed microscopic tumor islands (frequently without mass formation), extensive fibrosis, and abundant lymphocytic infiltration mimicking thyroiditis.

    Detection of antithyroid peroxidase antibody (TPOAb) is widely used in the diagnosis of autoimmune thyroiditis (AIT), but no research has evaluated the diagnostic accuracy of TPOAb detection using histopathologic reference standards. To fill this research gap, this study assessed the diagnostic accuracy of detection of TPOAb and that of other serological markers in asymptomatic patients who had been diagnosed with AIT by histopathologic analysis after thyroid surgery. After review of patient records, 598 patients who had undergone thyroid nodule surgery were enrolled for examination for thyroid parenchyma by a pathologist and classification into no co-existing lymphocytic thyroiditis, Hashimoto thyroiditis, or non-Hashimoto type of lymphocytic thyroiditis (NHLT). The correlation between patient serological data and thyroid parenchyma pathology was analyzed. Statistically significant differences (P lymphocytic thyroiditis and no co-existing lymphocytic thyroiditis groups regarding thyroid-stimulating hormone (TSH) and TPOAb levels. And, TPOAb titer was significantly associated with the degree of inflammation. An abnormal TPOAb titer was found in 86 of the 598 patients (14.4 %) and the specificity of TPOAb detection for AIT diagnosis was found to be 96.9 %. The prevalence of Hashimoto thyroiditis and NHLT in the 560 papillary thyroid cancer (PTC) patients was found to be 7.9 and 17.9 %, respectively. The results indicate that TPOAb titer is associated with the degree of thyroid inflammation and that detection of TPOAb is a very specific means of diagnosing AIT. The results also indicate that the incidence of AIT and PTC coexistence is relatively high.

    Background: Pregnancy has a huge impact on the thyroid function in both healthy women and those that have thyroid dysfunction. The prevalence of thyroid dysfunction in pregnant women is relatively high. Objective: The objective of this review was to increase awareness and to provide a review on adverse effect of thyroid dysfunction including hyperthyroidism, hypothyroidism and thyroid autoimmune positivity on pregnancy outcomes. Materials and Methods: In this review, Medline, Embase and the Cochrane Library were searched with appropriate keywords for relevant English manuscript. We used a variety of studies, including randomized clinical trials, cohort (prospective and retrospective), case-control and case reports. Those studies on thyroid disorders among non-pregnant women and articles without adequate quality were excluded. Results: Overt hyperthyroidism and hypothyroidism has several adverse effects on pregnancy outcomes. Overt hyperthyroidism was associated with miscarriage, stillbirth, preterm delivery, intrauterine growth retardation, low birth weight, preeclampsia and fetal thyroid dysfunction. Overt hypothyroidism was associated with abortion, anemia, pregnancy-induced hypertension, preeclampsia, placental abruption, postpartum hemorrhage, premature birth, low birth weight, intrauterine fetal death, increased neonatal respiratory distress and infant neuro developmental dysfunction. However the adverse effect of subclinical hypothyroidism, and thyroid antibody positivity on pregnancy outcomes was not clear. While some studies demonstrated higher chance of placental abruption, preterm birth, miscarriage, gestational hypertension, fetal distress, severe preeclampsia and neonatal distress and diabetes in pregnant women with subclinical hypothyroidism or thyroid autoimmunity; the other ones have not reported these adverse effects.

    Full Text Available Abstract Background In recent few years is underlined that altered balance of pro- and anti-inflammatory cytokines play an important role in the pathogenesis of AITD. The aim of this study was to estimate intracellular INF-γ and IL-4 levels in thyroid-infiltrating lymphocytes and thyrocytes isolated from thyroid tissues in 54 adolescent patients aged 8-21 years, with Graves' disease (GD; n = 18, Hashimoto's thyroiditis (HT; n = 18 and non-toxic multinodular goiter (NTMG; n = 18. Methods Fresh thyroid tissues were taken on culture medium RPMI -1640, it was mechanically prepared. In next step were added cell activators -12- myristate 13- the acetate (PMA and Ionomycin as well as the inhibitor of transportation of proteins - Breferdin A. They were cultured 24 hours in 50 ml flasks at 37°C in a 5-95% CO2-air water-saturated atmosphere. After that, thyrocytes were identified by mouse mAb directed against human TPO epitope 64 conjugated with rabbit anti-mouse antibodies IgG (Fab'2 labeled by FITC. After incubation at room temperature to each of samples added reagent A fixative the cellular membrane. In next step into the cell suspensions were added reagent B to permeabilization of cellular membrane and specific anti-IL-4-PE or anti-IFN-γ-PE mAbs. Identification of intracellular cytokines in T lymphocytes was performed in the same procedure with application of anti-CD4-PerCP and anti-CD8-PerCP mAbs specific for T lymphocytes. The cells were analyzed in a flow cytometry (Coulter EPICS XL. Results In examined group of patients with GD we observed statistically significant higher mean percentage of cells with phenotype CD4+IL-4 (p Conclusions We conclude that human thyrocytes in autoimmune thyroid disorders could be a source of cytokine production and that their activation influences local interaction with T lymphocytes inflowing to the thyroid gland.

    Thyroid autoimmunity is one of the most common immune disorders in females, and its polygenic background remains to be elucidated. The human leukocyte antigen (HLA) DQ region of chromosome 6 has been shown to confer susceptibility to thyroid autoimmune disease. The aim of our present investigation was to determine whether the transmission of high risk HLA DQ to patients with thyroid autoimmunity differs when transmission is from fathers as opposed to when transmission is from mothers. We studied 91 juvenile patients with chronic lymphocytic thyroiditis (68 females and 23 males; mean age, 10.5 +/- 3.9 yr), 12 patients with Graves' disease (all females; mean age, 8.8 +/- 4.0 yr), 53 healthy siblings, and their parents for thyroid function, antibodies, ultrasound, and DNA typing for HLA DQ susceptibility alleles. We observed an increased rate of transmission for the DQA1*0501-DQB1*0201 (DQ2) haplotype [35 of 53 transmitted (66%); P = 0.02]. This allele was preferentially transmitted by fathers [21 of 27 (78%); P < 0.004], whereas the maternal DQ2 haplotypes were not transmitted more often than expected. Subsequently, families were stratified as follows according to the parental thyroid peroxidase antibody (TPOAb) status: no parent, only mothers, only fathers, and both parents positive. There was no significant maternal transmission disequilibrium in any subset, but the paternal HLA DQ2 was preferentially transmitted [11 of 14 cases (79%); P = 0.03] in the group of TPOAb-positive mothers, and we observed a similar trend in the group of TPOAb- positive fathers (P = 0.08). Also, the portion of offspring affected by Graves' disease was significantly higher in TPOAb-positive than in TPOAb-negative fathers (P < 0.02). In conclusion, our findings demonstrate a significant effect of paternal HLA DQ alleles as well as antibody status on susceptibility to thyroid autoimmune disease in juvenile patients.

    Th primary thyroid lymphoma is a rare neoplasm, above all in children. We present a case of a child with Burkitt's thyroid lymphoma as the only manifestation of this disease, associated to lymphocytic thyroiditis. Clinically, it initiated as a rapidly growing goiter with compressive symptomatology. The X-ray findings are described: hypoechoic and hypodense multiple nodes that affect the right thyroid lobe and isthmus, with extraglandular extension to the vascular space and to the mediastinum. The differential diagnosis is considered with other more frequent thyroid pathologies in this age group. (Author) 14 refs.

    Full Text Available Background: Primary Thyroid Lymphoma (PTL is uncommon, accounting for only 5% of thyroid neoplasms and less than 2.5 to 7% of extranodal lymphomas. The study aims to analyze the histopathological findings and to correlate it with clinical features. Methods: This study includes cases of PTL received in the department of pathology in a tertiary care center, Kerala, south India over a period of 5 years. Patient details and follow up data were obtained by communication with treating doctors and reviewing the hospital records. All cases had a minimum follow up of 6 months. Results: 15 cases of PTL were diagnosed over the five year period. In total 72 cases of extranodal lymphomas were diagnosed, thus forming 20.83% of extra nodal lymphomas. Lymphocytic thyroiditis was present in 93.3%. Most of the cases were Extranodal Marginal Zone B Cell Lymphoma (EMZBCL and Diffuse Large B Cell Lymphoma (DLBCL. Conclusion: It is important to consider the diagnosis of primary thyroid lymphoma in patients presenting with an enlarging neck mass especially with the history of Hashimoto's thyroiditis. Random microscopic foci of DLBCL or small areas of MZBL could be overlooked examination or missed with limited sampling. The distinction between MZBL and DLBCL in the thyroid is clinically significant. [Int J Res Med Sci 2015; 3(3.000: 579-582

    Full Text Available Background. Hashimoto's thyroiditis (HT, also known as chronic lymphocytic thyroiditis or chronic autoimmune thyroiditis, is the most common form of thyroiditis affecting more than 10% of females and 2% of males. The present study aims to evaluate the beneficial effect of a combined treatment, Myo-Inositol plus selenomethionine, on subclinical hypothyroidism. Methods. The study was designed as a double-blind randomized controlled trial. Eligible patients were women diagnosed with subclinical hypothyroidism having Tg antibodies (TgAb titer higher than 350 IU/mL. Outcome measures were Thyroid Stimulating Hormone (TSH levels, thyroid peroxidase antibodies (TPOAb and TgAb titer, selenium, and Myo-Inositol plasma concentration. Results. In the present paper, we demonstrated that the beneficial effects obtained by selenomethionine treatment on patients affected by subclinical hypothyroidism, likely due to the presence of autoantibody (TPOAb and TgAb, are further improved by cotreatment with Myo-Inositol. Conclusions. Indeed, due to its action as TSH second messenger, Myo-Inositol treatment reduces TSH levels closer to physiological concentrations.

  1. Incidental Thyroid Carcinoma Diagnosed after Total Thyroidectomy for Benign Thyroid Diseases: Incidence and Association with Thyroid Disease Type and Laboratory Markers

    Directory of Open Access Journals (Sweden)

    D. Askitis

    2013-01-01

    Full Text Available Objective. Currently, total thyroidectomy (TT is widely used to treat benign thyroid diseases and thyroid carcinoma. The differential diagnosis between benign and malignant thyroid disorders and the potential identification of thyroid microcarcinomas with biochemical markers remain controversial. This retrospective study aimed to estimate the prognostic validity of thyroid autoantibodies, thyroglobulin (Tg, and the thyroid disease type in diagnostic approaches regarding the co-existence of incidental thyroid carcinoma (ITC with benign thyroid diseases. Methods. A cohort of 228 patients was treated with TT for benign thyroid disorders between 2005 and 2010. Thyroid autoantibodies and Tg were preoperatively estimated. Patients were classified according to the preoperative and histologically established diagnoses, and the median values of the biochemical markers were compared between the groups. Results. ITC was detected in 33/228 patients and almost exclusively in the presence of nontoxic thyroid disorders (. There were no statistically significant differences in the median values of the biochemical markers between the benign and malignant groups. There was also no significant association between ITC and chronic lymphocytic thyroiditis. Conclusions. The co-existence of ITC with benign and especially nontoxic thyroid diseases is significant, and treatment of these disorders with TT when indicated can lead to the identification and definitive cure of microcarcinomas. Further studies are required to establish precise markers with prognostic validity for TC diagnosis.

    The aim of report is to present a case of a rare diffuse sclerosing variant of a papillary thyroid carcinoma. A 15-year old girl referred for ultrasound examination because of painless thyroid swelling lasting 10 days before. An ultrasound of the neck showed diffusely changed thyroid parenchyma, without nodes, looking as lymphocytic thyroiditis Hashimoto at first, but with snow-storm appearance, predominantly in the right lobe. Positive thyroid peroxidase antibodies (TPO-AT) also suggested Hashimoto thyroiditis. Repeated US-FNAB (fine needle-aspiration biopsy) of the right lobe revealed diffuse sclerosing variant of papillary thyroid carcinoma and patient underwent total thyreoidectomy. Patohistologic finding confirmed diffuse sclerosing variant of a papillary thyroid carcinoma in the both thyroid lobes and several metastatic lymph nodes. Two months later patient recived radioablative therapy with 3700 MBq (100 mCi) of 1-131 followed by levothyroxine replacement. At the moment, patient is without evidence of local or distant metastases and next regular control is scheduled in 6 months. In conclusion, a diffuse sclerosing variant is rare form of papillary thyroid carcinoma that echographically looks similar to Hashimoto thyroiditis and sometimes could be easily overlooked.

    The authors report the case of a 70-year-old male patient with chronic lymphoid leukemia who presented subsequently a papillary carcinoma of the thyroid with metastases to regional lymph nodes. The patient was treated with surgical thyroidectomy with regional and cervical lymph node excision and radioiodine therapy (I-131). The protocolar control scintigraphy 4 days after the radioactive dose showed I-131 uptake in both axillae and even in the inguinal regions. PET/CT showed faint FDG-F-18 uptake in one lymph node of the left axilla. An ultrasound guided fine needle biopsy of this lymph node identified by I-131 SPECT/CT and FDG-F-18 PET/CT revealed lymphoma cells and was negative for thyroid tissue and thyroglobulin content. The sequential blood counts done routinely after radiation treatment showed a marked fall until return to normal values of leucocytes and lymphocytes (absolute and relative), which were still normal in the last control 19 months after the radioiodine administration. Chest computed tomography showed a decrease in size of axillary and paraaortic lymph nodes. By immunohistochemistry, cells of the lymphoid B lineage decreased from 52% before radioiodine therapy to 5% after the procedure. The authors speculate about a possible sodium iodide symporter expression by the cells of this lymphoma, similar to some other non-thyroid tumors, such as breast cancer cells. (author)

    Detection of BRAF mutation in cytology specimens has been proposed as a diagnostic adjunctive tool in evaluation of thyroid nodules with indeterminate cytology findings. Concurrent papillary thyroid carcinoma and Hashimoto's thyroiditis (HT), a disease characterized by thyroid lymphocytic infiltration, is a frequent occurrence. A large lymphocytic infiltrate might reduce the sensitivity of methods employed to detect BRAF mutation in thyroid cytology specimens. To determine whether testing for BRAF mutational status in fine needle aspirates (FNA) is reliable also in the presence of HT lymphocytic infiltration, we assessed the BRAF status by direct sequencing and pyrosequencing in a series of FNAs with and without concomitant HT lymphocytic infiltration. We also performed the same assessment by pyrosequencing in the corresponding tissue samples. Pyrosequencing demonstrated to be more sensitive than direct sequencing. The percentage of mutant BRAF(V600E) alleles was higher in FNAs than in the corresponding tissues, probably because of the lower stromal contamination in FNA than in the sections. In the presence of lymphocytic infiltration, the percentage of mutant BRAF(V600E) alleles determined by pyrosequencing was higher in FNAs than in the corresponding tissue samples (P lymphocytic contamination in FNA. The diagnostic value of BRAF(V600E) in inconclusive FNAs was not hampered by thyroid lymphocytic infiltration. These results indicate that BRAF(V600E) assessment by pyrosequencing is a reliable assay useful to refine inconclusive cytology of thyroid nodules also in the presence of concurrent HT.

    Platelets can modulate lymphocytes' role in the pathophysiology of thyroid autoimmune diseases. The present study was performed to clarify the status of platelet-lymphocyte subpopulations aggregation in circulating blood in patients with Graves' disease (GD). One hundred and fifty patients with GD (GD group) and 45 hyperthyroid patients with toxic multinodular goiter (TMG group) were recruited in the study. Control group consisted 150 healthy subjects. Immunophenotyping of lymphocytes was performed by flow cytometry. Detection of lymphocyte-platelet aggregates (LPAs) was done using light microscope after Ficoll-gradient centrifugation. The group of GD patients exhibited reduced CD8 lymphocyte and higher CD19 cell counts compared with TMG group and healthy controls. A greater number of activated CD3, HLA-DR+ lymphocytes were observed in GD than in TMG group and control group. GD group was characterized by lower blood platelet count (232 ± 89 × 10 cells/µL) than TMG group (251 ± 97 × 10 cells/µL; P < 0.05) and control group (262 ± 95 × 10 cells/µL; P < 0.05). In GD group, more platelet-bound lymphocytes (332 ± 91 /µL) were found than that in TMG group (116 ± 67/µL, P < 0.005) and control group (104 ± 58 /µL; P < 0.001). GD is associated with higher levels of activated lymphocytes and lymphocyte-platelet aggregates.

    Full Text Available Warthin-like papillary thyroid carcinoma is a rare variant of papillary thyroid carcinoma with favorable prognosis. The tumor is named “Warthin-like papillary thyroid carcinoma” because of bearing a striking morphological resemblance to Warthin’s tumor occurring in the salivary glands. Thyroid ultrasonography of 65 years old female patient with a history of bilateral subtotal thyroidectomy 30 years ago in another center with unknown histopathological diagnosis revealed a 20 mm isoechoic solid nodule in the left lobe and this nodule was hypoactive in thyroid scintigraphy. Grossly, a grey-tan colored, solid nodule with 1 cm diameter was seen in the left lobe. Histologically, the tumor was composed of papillary structures surrounded by marked lymphocytic stroma and oncocytic cells with papillary carcinoma’s nuclear features were lining the papillae. Hashimoto’s thyroiditis was present throughout the thyroid. Immunohistochemically, tumor cells exhibited cytokeratin 19, Thyroid transcription factor-1 (TTF-1, Galectin-3, HBME-1(Mesothelioma antibody and thyroglobulin positivity, proliferative index with Ki-67 was low. Warthin-like papillary thyroid carcinoma is a rare variant of papillary thyroid carcinoma and other oncocytic cell lesions especially Hurthle cell carcinoma should be kept in mind in the differential diagnosis of this neoplasm.

    Differentiated thyroid cancer (DTC) represents about 90% of thyroid malignancies with increasing incidence in the recent decades. Treatment modalities include thyroidectomy, {sup 131}I therapy (with or without r-hTSH), radio and chemotherapy. Little is known about the effects of these treatments at the cellular level. This work was proposed in order to assess to what extent radioiodine therapy can cause damage in peripheral lymphocytes of patients with DTC, preceded or not by r-hTSH, taking into account acute, slow and dosimetric effects of {sup 131}I (in vivo study). An in vitro study was also carried out on thyroid tumor target cells (WRO) by cytotoxicity and genotoxicity analysis and radioiodine uptake. For this, blood samples from patients divided into two groups (group A, r-hTSH + {sup 131}I and group B,{sup 131}I only) were collected before, 24 hours, 1 week, 1 month and 1 year after {sup 131}I administration for aberration chromosome analysis (CA). A dose-response curve for {sup 131}I in vitro was developed for estimating the absorbed dose in patients, comparing the dicentric frequencies obtained in vitro with in vivo data by Monte Carlo program. Radioiodine therapy induced an increase in the number of CA in lymphocytes of patients peaking 24 hours after treatment, with gradual decline over time and with more chromosomal damage in group B than in group A, reaching baseline levels one year after radioiodine administration. The frequency of dicentric found inpatient lymphocytes, 24h after treatment, was equivalent to that induced in vitro (0.354 ± 0.153 MBq / mL for group A and 0.309 ± 0.154 MBq / mL for group B), which corresponds to absorbed doses of 0.8 ± 0.3 Gy and 0.7 ± 0.3 Gy for groups A and B, respectively, with no significant difference between the groups. WRO cells showed a cell cycle relatively slow: 96,3h with an unstable karyotype. The genotoxic test showed a relatively high radioresistance (0.07 to 3.70 MBq/mL), with no statistical

    2012-06-01

    Full Text Available Abstract Background Parathyroid metastatic disease from thyroid cancer has not been studied extensively, mainly due to the need for parathyroid preservation during thyroid surgery. Methods We reviewed files from 1,770 patients with thyroid cancer followed up in our department and 10 patients with parathyroid metastases (0.5% were identified. Patient and tumor characteristics were recorded. Results Six out of ten patients had metastases from papillary thyroid cancer, three from follicular thyroid cancer and one from anaplastic thyroid cancer. In nine patients parathyroid infiltration from thyroid cancer was found in direct contact with the thyroid cancer, and in one patient metastatic foci were observed not in continuity with the thyroid cancer. Conclusions Parathyroid involvement, although infrequent, may occur in thyroid cancer independently of patient age and tumor size. The clinical significance of such event is not clear. The influence on disease outcome remains to be elucidated.

    Full Text Available A case of a 40-year-old woman who was suffering from painless thyroiditis with recurrent transient thyrotoxicosis is reported. Acute exacerbations occurred four times during the past ten years, two after delivery and two after catching a cold. Serum thyroid hormones increased, though radioiodine uptake by the thyroid was very low and no inflammatory signs were observed. The histological findings of the thyroid were of atypical thyroiditis and not consistent with either chronic lymphocytic thyroiditis or subacute thyroiditis. Tanned sheep red cell hemagglutination titers for anti-thyroglobulin antibodies (TRC and for anti-microsomal antibodies (MHA were negative or low. The disease seems to be rare and the pathophysiology and etiology are discussed.

    Background: An in-depth understanding of the fundamental principles that regulate thyroid hormone homeostasis is critical for the development of new diagnostic and treatment approaches for patients with thyroid disease. Summary: Important clinical practices in use today for the treatment of patients with hypothyroidism, hyperthyroidism, or thyroid cancer are the result of laboratory discoveries made by scientists investigating the most basic aspects of thyroid structure and molecular biology. In this document, a panel of experts commissioned by the American Thyroid Association makes a series of recommendations related to the study of thyroid hormone economy and action. These recommendations are intended to promote standardization of study design, which should in turn increase the comparability and reproducibility of experimental findings. Conclusions: It is expected that adherence to these recommendations by investigators in the field will facilitate progress towards a better understanding of the thyroid gland and thyroid hormone dependent processes.

    Full Text Available Abstract Background We aimed to evaluate thyroid functions and volumes and detect abnormalities in 80 neonates with Down syndrome. Methods Data about free triiodothyronine, free thyroxine, thyroid stimulating hormone, thyroglobulin and urinary iodine levels, and ultrasonographic thyroid volume were collected. Results Abnormal thyroid function tests were detected in 53.8% of the patients (n = 50 and these were hyperthyrotropinemia, hypothyroidism, iodine deficiency and iodine overload in 32, 2, 12 and 4 patients, respectively. Thyroid volumes were assessed in 36 patients and a total of 17 abnormalities were detected (7 hypoplasia, 3 agenesis and 7 goiter. In patients with hyperthyrotropinemia mean thyroid volume was significantly greater and mean TSH was significantly higher when compared to the patients without hyperthyrotropinemia. Conclusion Neonatal screening by thyroid function tests in Down syndrome should be performed to prevent further intellectual deterioration and improve overall development. In the neonatal period, the risk of hyperthyrotropinemia should be kept in mind.

    To evaluate the diagnostic values of gray-scale and color Doppler ultrasound in the diagnosis of focal Hashimoto's thyroiditis (FHT). The gray-scale and colour Doppler ultrasound data of 120 patients with histopathologically confirmed FHT were retrospectively studied. The background of thyroid parenchyma was subjectively evaluated as absence or presence of diffuse Hashimoto's thyroiditis. The vascular types of thyroid nodules were determined as follows: hypovascularity, marked internal flow, marked peripheral flow, and focal thyroid inferno. Among all 120 nodules, 71 (59.2%) were located in normal thyroid parenchyma, 49 (40.8%) in the background of diffuse Hashimoto's thyroiditis. In the normal thyroid background, hypoechoic nodules accounted for 85.9% (61/71), and only 14.1% (10/71)nodules were isoechoic or hyperechoic. However, in the background of diffuse Hashimoto's thyroiditis, 40.8% were hypoechoic and 59.2% were isoechoic or hyperechoic. The difference was statistically significant (Pinferno accounted for 45 %, 25.9%, 20.8%, and 8.3%, respectively. The "focal inferno" is a relative specific color Doppler feature of FHT.

    Hashimoto thyroiditis (HT), now considered the most common autoimmune disease, was described over a century ago as a pronounced lymphoid goiter affecting predominantly women. In addition to this classic form, several other clinico-pathologic entities are now included under the term HT: fibrous variant, IgG4-related variant, juvenile form, Hashitoxicosis, and painless thyroiditis (sporadic or post-partum). All forms are characterized pathologically by the infiltration of hematopoietic mononuclear cells, mainly lymphocytes, in the interstitium among the thyroid follicles, although specific features can be recognized in each variant. Thyroid cells undergo atrophy or transform into a bolder type of follicular cell rich in mitochondria called Hürthle cell. Most HT forms ultimately evolve into hypothyroidism, although at presentation patients can be euthyroid or even hyperthyroid. The diagnosis of HT relies on the demonstration of circulating antibodies to thyroid antigens (mainly thyroperoxidase and thyroglobulin) and reduced echogenicity on thyroid sonogram in a patient with proper clinical features. The treatment remains symptomatic and based on the administration of synthetic thyroid hormones to correct the hypothyroidism as needed. Surgery is performed when the goiter is large enough to cause significant compression of the surrounding cervical structures, or when some areas of the thyroid gland mimic the features of a nodule whose cytology cannot be ascertained as benign. HT remains a complex and ever expanding disease of unknown pathogenesis that awaits prevention or novel forms of treatment.

    2012-01-01

    Full Text Available Hashimoto′s thyroiditis (HT, an autoimmune disorder, is the most prevalent cause of subclinical or overt hypothyroidism in areas with sufficient iodine intake. The gland is often diffusely enlarged, and the parenchyma is coarsened, hypoechoic, and often hypervascular on ultrasonograpy. Histopathologic appearance of HT includes lymphocyte aggregates with germinal centers, small thyroid follicles, presence of Hurthle cells, and variable fibrosis. We present a case of a 40-year-old female with suspected follicular neoplasm on fine-needle aspiration cytology of neck swelling. Intraoperatively, thyroid gland was found having four lobes separated from each other. Total thyroidectomy was done and histopathology from all four lobes revealed HT. At present, there is no literature to support the fact that such distorted thyroid anatomy may be due to the underlying disease. If we consider it as thyroid gland anomaly, no such anomaly has been mentioned in the literature till date.

    The key to uncovering the etiology of hyperthyroidism lies in a careful history and physical examination. Autoimmune markers provide additive information, but should not solely be used to make a diagnosis. Concern has been raised that the overzealous use of thyroid ultrasound, following abnormal thyroid function tests, diverts attention from the workup of the biochemical abnormality to the workup of an incidentally found thyroid nodule. If further imaging is needed, the use ofathyroidscanhas been suggestedbythe Endocrine Society and the American Association of Clinical Endocrinologists. However, in certain scenarios, this may be contraindicated. We present the case of a 28-year-old female with hyperthyroidism, as aplatform to discuss an important clinical sign present on Doppler ultrasound of the thyroid. By recognizing the clinical information gained from a Doppler ultrasound, physicians can avoid additional invasive workup and apply the use of ultrasound where most appropriate.

    Abnormally elevated serum T3 concentrations measured by RIA were observed in 19 clinically euthyroid or hypothyroid mongrel dogs. The serum T4 concentrations in these sera were low, normal, or high. Measurement of the intensity of thyroid hormone binding to serum proteins was determined by equilibrium dialysis. A marked decrease in the percent free T3 was observed in these abnormal sera. Polyacrylamide gel electrophoresis, pH 7.4, of normal dog serum enriched with tracer /sup 125/I-labeled thyroid hormones demonstrated binding of (/sup 125/I)T4 to transthyretin, thyroid hormone-binding globulin, and albumin and of (/sup 125/I)T3 primarily to thyroid hormone-binding globulin. In all abnormal sera, polyacrylamide gel electrophoresis demonstrated strikingly higher binding of T3 to immunoglobulin (Ig). Eleven of 16 abnormal sera had minimal to moderate binding of T4 to Ig. The percent free T4 was lower only in dogs whose sera demonstrated markedly increased binding of T4 to Ig. All abnormal sera tested had positive antithyroglobulin antibodies, consistent with the diagnosis of autoimmune lymphocytic thyroiditis. As in humans, antibodies to thyroid hormones in dogs are more common in the presence of Hashimoto's thyroiditis and should be considered when elevated serum thyroid hormone concentrations are observed in the absence of clinical thyrotoxicosis. When an antibody to only one thyroid hormone is present, a marked discrepancy in the serum concentrations of T3 and T4 will be observed.

    2010-01-01

    Full Text Available Aim: Our study aimed at a cell pattern approach to interpret thyroid cytology and to demonstrate diagnostic accuracy of fine needle aspiration cytology (FNAC with an emphasis on diagnostic pitfalls. Materials and Methods: A total number of 218 goitre cases, from the year 2000 to 2004, were reviewed retrospectively from the cytology files, without considering the previous cytological diagnosis. Four cases with inadequate aspirate were excluded. The predominant cell pattern, such as macro/normofollicular, microfollicular, papillary, syncytial, dispersed and cystic pattern, was noted in each case. The final diagnosis was arrived by observing the cellular details and background elements. Cytological diagnosis was correlated with histopathology in 75 cases. The sensitivity and specificity were computed. Results: Normo/macrofollicular pattern was seen in 71.96% of nodular goitre and 6.9% of follicular neoplasms. Around 86.2% of follicular neoplasms and 17.6% of papillary carcinoma had microfollicular pattern. The papillary pattern was seen in 47% of papillary carcinoma. Syncytial pattern was noticed in 72.3% of chronic lymphocytic thyroiditis and 29.4% of papillary carcinoma. Cytological diagnosis was concordant with histopathological diagnosis in 65 cases. Overall sensitivity and specificity of FNAC in diagnosing neoplastic lesions of thyroid were 83.33 and 95.55%, respectively. Conclusion: FNAC is more sensitive and specific in triaging neoplastic from non-neoplastic thyroid lesions. Identification of the predominant cell pattern would be complementary to analysis of cell morphology and background details in cytological diagnosis of thyroid lesions. This approach helps to diagnose follicular neoplasm and follicular variant of papillary thyroid carcinoma.

    Full Text Available Background. Simultaneous presence of Hashimoto's thyroiditis and papillary thyroidal carcinoma in thyroidal gland with papillary carcinoma association in thyroglossal duct is quite rare. The questions like where the original site of primary process, is where metastasis is, what the cause of coexisting of these diseasesis present a diagnostic dilemma. Case report. We presented a case of a 53-year old female patient, with the diagnosis of Hashimoto's thyroiditis and symptoms of subclinical hypothyreosis and nodal changes in the right lobe of thyroidal gland, according to clinical investigation. Morphological examination of thyroidal gland, ultrasound examination and scintigraphy with technetium (Tc confirmed the existence of nonhomogenic tissue with parenchyma nodular changes in the right lobe of thyroidal gland that weakly bonded Tc. Fine needle biopsy in nodal changes, with cytological analyses showed no evidence of atypical thyreocites. Hashimoto's thyroiditis was confirmed on the basis of the increased values of anti-microsomal antibodies, the high levels of thyreogobulin 117 ng/ml and TSH 6.29 μIU/ml. The operation near by the nodular change in the right lobe of thyroidal gland revealed pyramidal lobe spread in the thyroglossal duct. Total thyroidectomia was done with the elimination of thyroglossal duct. Final patohystological findings showed papillary carcinoma in the nodal changes pT2, N0 and in the thyroglossal duct with the presence of Hashimoto's thyroiditis in the residual parenchyme of the thyroid gland. After the surgery the whole body scintigraphy with iodine 131 (131I did not reveal accumulation of 131I in the body, while the fixation in the neck was 1%. After that, the patient was treated with thyroxin with suppressionsubstitution doses. Conclusion. Abnormality in embrional development of thyroidal tissue might be the source of thyroidal carcinoma or the way of spreading of metastasis of primary thyroidal carcinoma from thyroid

    Full Text Available Objective: The objectives were to evaluate fine needle aspiration cytology results of 39 pediatric patients, and the pathologies that cause childhood thyroid nodules, and to review the literature on the subject.Material and Method: Thyroid fine needle aspiration cytology results of 39 pediatric patients were retrospectively reviewed. Associated diseases, thyroid functions, anti-thyroid antibody levels, ultrasonographic findings and number of nodules were also evaluated.Results: The vast majority of patients with thyroid nodules were cytopathologically diagnosed as benign (97.3%. Of these patients, 64.8% (24 patients were diagnosed as nodular goiter and 35.2% (13 patients as lymphocytic thyroiditis. Thyroid malignancy was found in two patients; one was diagnosed as follicular neoplasm/ minimal invasive follicular carcinoma on surgical evaluation while the other was a secondary tumor (Burkitt's lymphoma. The majority of our subjects were females (66.6%: the female/male ratio was 2:1 for nodular goiter and 3.3:1 for thyroiditis. Surgical resection was performed in 5 patients (4 cases of nodular goiter, 1 suspicious for malignancy and cytological diagnoses were confirmed by histology.Conclusion: Our study confirmed the utility of fine needle aspiration cytology in childhood thyroid disorders along with a possible higher incidence of nodular thyroiditis in childhood. Nodular autoimmune thyroiditis, focal thyroiditis and thyroid cancer in children are discussed and attention is drawn to some special subtypes of thyroid cancer and some benign lesions that can cause difficulty in interpreting fine needle aspiration cytology and frozen sections at this age.

    2009-09-01

    Full Text Available Abstract Background Primary thyroid gland lymphomas are uncommon tumours that occur in the setting of lymphocytic thyroiditis or Hashimoto's disease in almost all cases. In this condition a distinction between an inflammatory lymphoid infiltrate and a low grade lymphoma may be extremely difficult and precise criteria are necessary for a correct diagnosis. Patient and methods We report a case of a minute focus of primary extranodal marginal zone B-cell lymphoma (EMZBCL, incidentally discovered in a 63-year-old man with Hashimoto thyroiditis (HT and diagnosed by means of polymerase chain reaction (PCR after laser capture microdissection. The histological examination of surgical specimen confirmed the diagnosis of HT and showed a minute focus of dense lymphoid infiltrate (less than 4 mm in diameter, composed by centrocyte-like cells forming MALT balls. Immunoistochemistry was not useful. A microscopic focus of EMZBCL was suspected on the basis of morphological features. PCR assays revealed the rearrangement of the heavy chain of immunoglobulins only in the microdissected suspicious area, confirming the diagnosis of EMZBCL. Conclusion Our finding suggests that in cases of autoimmune thyroiditis a careful examination of the thyroid specimen is warranted, in order to disclose areas or small foci of lymphomatous transformation. Furthermore, in difficult cases with doubtful immunohistological findings, ancillary techniques, such as molecular studies, are necessary for a conclusive diagnosis.

  15. Thyroid hormone-regulated gene expression in juvenile mouse liver: identification of thyroid response elements using microarray profiling and in silico analyses

    Directory of Open Access Journals (Sweden)

    Paquette Martin A

    2011-12-01

    Full Text Available Abstract Background Disruption of thyroid hormone signalling can alter growth, development and energy metabolism. Thyroid hormones exert their effects through interactions with thyroid receptors that directly bind thyroid response elements and can alter transcriptional activity of target genes. The effects of short-term thyroid hormone perturbation on hepatic mRNA transcription in juvenile mice were evaluated, with the goal of identifying genes containing active thyroid response elements. Thyroid hormone disruption was induced from postnatal day 12 to 15 by adding goitrogens to dams' drinking water (hypothyroid. A subgroup of thyroid hormone-disrupted pups received intraperitoneal injections of replacement thyroid hormones four hours prior to sacrifice (replacement. An additional group received only thyroid hormones four hours prior to sacrifice (hyperthyroid. Hepatic mRNA was extracted and hybridized to Agilent mouse microarrays. Results Transcriptional profiling enabled the identification of 28 genes that appeared to be under direct thyroid hormone-regulation. The regulatory regions of the genome adjacent to these genes were examined for half-site sequences that resemble known thyroid response elements. A bioinformatics search identified 33 thyroid response elements in the promoter regions of 13 different genes thought to be directly regulated by thyroid hormones. Thyroid response elements found in the promoter regions of Tor1a, 2310003H01Rik, Hect3d and Slc25a45 were further validated by confirming that the thyroid receptor is associated with these sequences in vivo and that it can bind directly to these sequences in vitro. Three different arrangements of thyroid response elements were identified. Some of these thyroid response elements were located far up-stream (> 7 kb of the transcription start site of the regulated gene. Conclusions Transcriptional profiling of thyroid hormone disrupted animals coupled with a novel bioinformatics search

    Full Text Available Background. Antinuclear antibodies (ANA are a hallmark of many autoimmune diseases and can be detected many years before disease onset. Autoimmune thyroid diseases (AITD are frequently associated with other organ- and non-organ-specific autoimmune disorders. Objectives. To assess the prevalence of ANA in pediatric patients with AITD and their clinical correlations. Methods. Ninety-three consecutive pediatric patients with AITD were enrolled (86 children with chronic lymphocytic thyroiditis and 7 with Graves’ disease. ANA, anti-double DNA (anti-dsDNA antibodies, anti-extractable nuclear antigen (anti-ENA, anti-cyclic citrullinated peptide antibodies (anti-CCP, and rheumatoid factor (RF was obtained. Signs and symptoms potentially related to rheumatic diseases in children were investigated by a questionnaire. Results. ANA positivity was found in 66/93 children (71%, anti-ENA in 4/93 (4.3%, anti-dsDNA in 1/93 (1.1%, RF in 3/93 (3.2%, and anti-CCP in none. No significant differences were found between the ANA-positive and ANA-negative groups with respect to age, sex, L-thyroxine treatment, or prevalence of other autoimmune diseases. Overall, parental autoimmunity was found in 23%. Conclusions. ANA positivity was demonstrated in 71% of children with AITD. ANA positivity was not related to overt immune-rheumatic diseases. However, because the positivity of ANA can occur even many years before the onset of systemic autoimmune diseases, prospective studies are warranted.

    Full Text Available OBJECTIVES: Forkhead box P3 (FoxP3 expression has been observed in human cancer cells but has not yet been reported in thyroid cells. We investigated the prognostic significance of both FoxP3 expression and intratumoral FoxP3+ lymphocyte infiltration in differentiated thyroid carcinoma cells. METHODS: We constructed a tissue microarray with 385 thyroid tissues, including 266 malignant tissues (from 253 papillary thyroid carcinomas and 13 follicular carcinomas, 114 benign lesions, and 5 normal thyroid tissues. RESULTS: We determined the expression of FoxP3 in both tumor cells and tumor-infiltrating lymphocytes using immunohistochemical techniques. Cellular expression of FoxP3 was evident in 71% of benign and 91.9% of malignant tissues. The nuclear and cytoplasmic expression patterns were quantified separately. A multivariate logistic regression analysis indicated that cytoplasmic FoxP3 expression is an independent risk factor for thyroid malignancy. Cytoplasmic FoxP3 staining was inversely correlated with patient age. Nuclear FoxP3 staining was more intense in younger patients and in tumors presenting with metastasis at diagnosis. FoxP3+ lymphocytes were more frequent in tumors smaller than 2 cm, those without extrathyroidal invasion, and in patients with concurrent chronic lymphocytic thyroiditis. CONCLUSIONS: We demonstrated FoxP3 expression in differentiated thyroid carcinoma cells and found evidence that this expression may exert an important influence on several features of tumor aggressiveness.

    2014-10-01

    In the context of a study on the tolerance of rapeseed meal in B.U.T. 6 turkeys, thyroid glands were histologically and immunohistochemically examined because of potential thyreostatic effects. In all groups including the controls with no rapeseed meal in their food, there was a high incidence of lymphocytic infiltration and thyroiditis (14% of thyroids with moderate to severe lymphocytic thyroiditis). Thirty per cent of mononuclear inflammatory cells were immunohistochemically identified as T cells. There were occasional accumulations of PAX-5 labelled cells, indicating germinal centre development. These lesions resemble Hashimoto's disease in humans. The effect on thyroid function is unknown. Mild hypothyreosis might enhance productivity but also explain dispositions towards diseases seen in context with thyroid dysfunction such as skin diseases (foot pad disease?) and cardiovascular problems. Further studies on thyroid function in these turkeys are needed.

    Full Text Available Objective. Black thyroid is a rare pigmented change seen almost exclusively in patients upon minocycline ingestion, and the process has previously been thought to be generally benign. There have been 61 reported cases of black thyroid. We are aware of 13 cases previously reported in association with thyroid carcinoma. This paper reports six patients with black thyroid pigmentation in association with thyroid carcinoma. Design. The medical records of six patients who were diagnosed with black thyroid syndrome, all of whom underwent thyroid surgery, were reviewed. Data on age, gender, race, preoperative fine needle aspiration biopsy (FNA, thyroid function levels, and pathology reports were collected. Main Outcome. The mean age was 60 years. There were 5 females, 4 of whom were African American. All patients were clinically and biochemically euthyroid. Black pigmentation was not diagnosed in preoperative FNA, and only one patient had a preoperative diagnosis of papillary thyroid carcinoma. The other patients underwent surgery and were found to have black pigmentation of the thyroid associated with carcinoma. Conclusions. FNA does not diagnose black thyroid, which is associated with thyroid carcinoma. Thyroid glands with black pigmentation deserve thorough pathologic examination, including several sections of each specimen.

    Background: Anaplastic thyroid carcinoma is rare but is one of the most aggressive malignancies. Therefore, accurate diagnosis is important in order to provide appropriate therapy. Purpose: To establish useful computed tomographic (CT) criteria for differentiating anaplastic carcinoma from other thyroid masses. Material and Methods: The CT scans of nine patients with anaplastic carcinomas were retrospectively reviewed and compared with those of 32 patients with papillary carcinomas (n = 12) or benign lesions (n = 20) exceeding a maximum diameter of 2.0 cm. Image analysis was performed according to the following CT parameters: size, margin (well defined or ill defined), composition (cystic, mixed, or solid), mean attenuation value, ratio of attenuation of the mass to that of the adjacent muscle (M/m attenuation ratio), necrosis (present or absent), and calcification (stippled, nodular, or absent) of the thyroid mass; and tumor-spreading patterns including the presence of surrounding normal thyroid tissue in the involved lobe, involvement of the contralateral thyroid lobe, extension into the adjacent structures, and cervical lymphadenopathy. Results: Anaplastic carcinomas appeared as large (average 4.6 cm), solid (100%), and ill-defined (88.9%) masses accompanied by necrosis (100%), nodular calcification (44.4%), direct invasion into the adjacent organs (55.6%), and cervical lymph node involvement (77.8%). Tumor necrosis was the most valuable parameter in differentiating anaplastic carcinomas from other thyroid masses. Patient age (>70 years) and low attenuation value on postcontrast scan (attenuation value <100 HU, or M/m attenuation ratio <1.3) are also helpful predictors for anaplastic carcinoma. Conclusion: If a patient is older than 70 years of age and has a large necrotic thyroid mass of low attenuation, anaplastic carcinoma should be included in the differential diagnosis

    None of the in-vitro and in-vivo methods listed permits on unambiguous diagnosis when applied alone, owing to the fact that similar or even identical findings are obtained for various individual parameters in different thyroid diseases. Further, especially the in-vitro tests are also subject to extrathyroidal effects which may mask the typical findings. The limited and varying specificity and sensitivity of the tests applied, as well as the falsification of results caused by the patients' idiosyncracies and the methodology, make it necessary to interpret and evaluate the in-vivo and in-vitro findings only if the clinical situation (anamnesis and physical examination) is known. For maximum diagnostic quality of the tests, the initial probability of the assumed type of thyroid disease must be increased (formulation of the clinical problem). The concepts of exclusion diagnosis and identification must be distinguished as well as the diagnosis of functional disturbances on the one hand and of thyroid diseases on the other. Both of this requires a qualified, specific and detailed anamnesis and examination procedure, and the clinical examination remains the obligatory basis of clinical diagnostics. In case of inexplicable discrepancies between the clinical manifestations and the findings obtained with specific methods, or between the findings obtained with a specific method, the patient should be referred to an expert institution, or the expert institution should be consulted.

  6. Stemness is derived from thyroid cancer cells

    Directory of Open Access Journals (Sweden)

    2014-07-01

    Full Text Available Background: One hypothesis for thyroid cancer development is its derivation from thyroid cancer stem cells (CSCs. Such cells could arise via different paths including from mutated resident stem cells within the thyroid gland or via epithelial to mesenchymal transition (EMT from malignant cells since EMT is known to confer stem-like characteristics. Methods: To examine the status of stemness in thyroid papillary cancer we employed a murine model of thyroid papillary carcinoma and examined the expression of stemness and EMT using qPCR and histochemistry in mice with a thyroid-specific knock-in of oncogenic Braf (LSL-Braf(V600E/TPO-Cre. This construct is only activated at the time of thyroid peroxidase (TPO expression in differentiating thyroid cells and cannot be activated by undifferentiated stem cells which do not express TPO.Results: There was decreased expression of thyroid specific genes such as Tg and NIS and increased expression of stemness markers such as Oct4, Rex1, CD15 and Sox2 in the thyroid carcinoma tissue from 6 week old BRAFV600E mice. The decreased expression of the epithelial marker E-cadherin and increased EMT regulators including Snail, Slug, and TGF-β1 and TGF-β3, and the mesenchymal marker vimentin demonstrated the simultaneous progression of EMT and the CSC-like phenotype. Stemness was also found in a derived cancer thyroid cell line in which overexpression of Snail caused up-regulation of vimentin expression and up regulation of stemness markers Oct4, Rex1, CD15 with enhanced migration ability of the cells. Conclusions: Our findings support our earlier hypothesis that stemness in thyroid cancer is derived via EMT rather than from resident thyroid stem cells. In mice with a thyroid-specific knock-in of oncogenic Braf (LSL-Braf(V600E/TPO-Cre the neoplastic changes were dependent on thyroid cell differentiation and the onset of stemness must have been derived from differentiated thyroid epithelial cells.

    Full Text Available We report the case of a 45-year-old man who presented with a 4-year history of midline neck swelling associated with recent onset respiratory distress. Local examination showed a lobulated diffuse thyroid enlargement. A subtotal thyroidectomy was performed. The right lobe weighed 225 g and the left lobe weighed 130 g. Multiple sections from both the lobes revealed diffuse infiltration of the stroma by mature adipose tissue. There was no evidence of amyloid deposits or papillary carcinoma. A final diagnosis of diffuse lipomatosis of the thyroid gland was rendered. Lipomatosis or adenolipomatosis of the thyroid gland is an extremely rare entity. The various differential diagnoses of fat in the thyroid include benign entities like amyloid goiter, adenolipoma, lymphocytic thyroiditis, intrathyroid thymic or parathyroid lipoma and malignant tumors like liposarcoma and encapsulated papillary carcinoma. Adequate clinical details and a thorough histopathological examination are mandatory for diagnosis.

    2014-01-01

    Hashimoto's thyroiditis (HT) has been found to be associated with lymphoma, papillary carcinoma and Hürthle cell neoplasms of thyroid. In contrast, there are only a few reports of co-existence of HT with medullary carcinoma of thyroid. An overall prevalence of medullary carcinoma of only 0.35% has been reported in HT patients. Such a rare combination is being presented here. A 33 year old female presented with history of goiter for one year. Fine needle aspiration cytology (FNAC) of the swelling revealed cytological features suggestive of medullary carcinoma of thyroid. Histopathological examination of total thyroidectomy specimen revealed Hashimoto's thyroiditis along with medullary carcinoma of thyroid. Although Hashimoto's thyroiditis can uncommonly co-exist with thyroid neoplasm, its association with medullary carcinoma is extremely rare and hence being presented.

    Full Text Available Abstract Background From animal studies it is known that currently used pesticides can disturb thyroid function. Methods In the present study we investigated the thyroid function in 122 Danish greenhouse workers, to evaluate if greenhouse workers classified as highly exposed to pesticides experiences altered thyroid levels compared to greenhouse workers with lower exposure. Serum samples from the greenhouse workers were sampled both in the spring and the fall to evaluate if differences in pesticide use between seasons resulted in altered thyroid hormone levels. Results We found a moderate reduction of free thyroxine (FT4 (10–16% among the persons working in greenhouses with a high spraying load both in samples collected in the spring and the fall, but none of the other measured thyroid hormones differed significantly between exposure groups in the cross-sectional comparisons. However, in longitudinal analysis of the individual thyroid hormone level between the spring and the fall, more pronounced differences where found with on average 32% higher thyroid stimulating hormone (TSH level in the spring compared to the fall and at the same time a 5–9% lower total triiodthyroxin (TT3, free triiodthyroxine (FT3 and FT4. The difference between seasons was not consistently more pronounced in the group classified as high exposure compared to the low exposure groups. Conclusion The present study indicates that pesticide exposure among Danish greenhouse workers results in only minor disturbances of thyroid hormone levels.

    Full text of the publication follows: The thyroid gland in children is among the most sensitive organs to the carcinogenic effects of ionizing radiation, and very young children are at especially high risk. Due to extreme sensitivity of the thyroid gland in children, there is a risk of radiation - induced thyroid cancer even when the thyroid gland is outside the irradiated field. Increased incidence of thyroid cancer has been noted following radiotherapy not only for childhood Hodgkin disease (majority of observed patients), but also for non-Hodgkin lymphoma, neuroblastoma, Wilms tumor, acute lymphocytic leukemia and tumors of the central nervous system also. Radiation-induced tumors begin to appear 5-10 years after irradiation and excess risk persists for decades, perhaps for the remainder of life. The incidence of thyroid cancer is two- to threefold higher among females than males. Most of the thyroid cancers that occur in association with irradiation are of the papillary type, for which the cure rate is high if tumors are detected early. Our Department in co-operation with Department of Children Hematology and Oncology Charles University Second Faculty of Medicine and Faculty Hospital Motol monitors patients after therapy for cancer in childhood for the long term period. The monitoring is focused on detection of thyroid disorders that occur as last consequences of oncology therapy, especially early detection of nodular changes in thyroid gland and thyroid carcinogenesis. The survey presents two patients observed in our department that were diagnosed with the papillary thyroid carcinoma which occurred 15 and more years after radiotherapy for childhood cancer. After total thyroidectomy they underwent therapy with radioiodine. After radiotherapy it is necessary to pursue a long-term following and assure interdisciplinary co-operation which enables early detection of last consequences of radiotherapy, especially the most serious ones as secondary carcinogenesis

  14. Ectopic cervical thymoma mimicking as papillary thyroid carcinoma: A diagnostic dilemma

    2010-04-01

    Full Text Available Ectopic cervical thymomas are often confused with thyroid or parathyroid swellings due to their anatomical positioning. Predominant epithelial thymoma can be misdiagnosed as papillary thyroid carcinoma on fine needle aspiration and lymph node metastasis of epithelial tumor on frozen section. Predominantly lymphocytic thymomas have often been misinterpreted as Hashimoto′s thyroiditis or malignant lymphoma, either by fine needle aspiration or on frozen section analysis. If cytology is doubtful and is not correlating with clinical, anatomical and surgical findings; immunohistochemistry is a very important tool in such cases to give final answer. Thyroid cell specific proteins such as thyroglobulin, thyroid transcription factor-1, thyroperoxidase and dipeptidyl aminopeptidase-4, neuroendocrine markers chromogranin, calcitonin and parathyroid hormone could be used to rule out thyroid or parathyroid origin. We present such rare case of ectopic cervical thymoma mimicking as papillary thyroid carcinoma.

    The aim of this study was to compare the diagnostic values of thyroid ultrasound (US) and neck computed tomography (CT) in incidentally detecting diffuse thyroid disease (DTD). A single radiologist made US and CT diagnoses of incidentally detected DTD in 130 consecutive patients before thyroidectomy for various malignancies. Histopathologic examinations confirmed normal thyroid (n = 80), Hashimoto thyroiditis (n = 20), non-Hashimoto lymphocytic thyroiditis (n = 28) and diffuse hyperplasia (n = 2). Receiver operating characteristic curves revealed that the best diagnostic indices of both imaging methods were achieved on the basis of two or more abnormal imaging findings. The sensitivity, specificity and accuracy of US and CT in incidentally detecting DTD by this classification were 72% and 72%, 87.5% and 91.3% and 81.5% and 83.8%, respectively. Thyroid US and neck CT have similar diagnostic values for differentiating incidental DTD from normal thyroid.

    Thyroiditis is a general term that encompasses several clinical disorders characterized by inflammation of the thyroid gland. The most common is Hashimoto thyroiditis; patients typically present with a nontender goiter, hypothyroidism, and an elevated thyroid peroxidase antibody level. Treatment with levothyroxine ameliorates the hypothyroidism and may reduce goiter size. Postpartum thyroiditis is transient or persistent thyroid dysfunction that occurs within one year of childbirth, miscarriage, or medical abortion. Release of preformed thyroid hormone into the bloodstream may result in hyperthyroidism. This may be followed by transient or permanent hypothyroidism as a result of depletion of thyroid hormone stores and destruction of thyroid hormone-producing cells. Patients should be monitored for changes in thyroid function. Beta blockers can treat symptoms in the initial hyperthyroid phase; in the subsequent hypothyroid phase, levothyroxine should be considered in women with a serum thyroid-stimulating hormone level greater than 10 mIU per L, or in women with a thyroid-stimulating hormone level of 4 to 10 mIU per L who are symptomatic or desire fertility. Subacute thyroiditis is a transient thyrotoxic state characterized by anterior neck pain, suppressed thyroid-stimulating hormone, and low radioactive iodine uptake on thyroid scanning. Many cases of subacute thyroiditis follow an upper respiratory viral illness, which is thought to trigger an inflammatory destruction of thyroid follicles. In most cases, the thyroid gland spontaneously resumes normal thyroid hormone production after several months. Treatment with high-dose acetylsalicylic acid or nonsteroidal anti-inflammatory drugs is directed toward relief of thyroid pain.

    Full Text Available Background: Using of CD10 in accordance with clinical and histological features of thyroid lesions could be used as both diagnostic and prognostic tool, which consequently influence the management and their prognosis for survival of patients with thyroid neoplasms especially papillary thyroid carcinoma (PTC. The aim of this study was to determine its expression in PTC and different benign thyroid lesions. Materials and Methods: In this descriptive-analytic, cross-sectional study, paraffin-embedded tissues of patients with definitive pathologic diagnosis of different benign thyroid lesions and PTC were retrieved. Immunostained sections of each slides was performed using immunohistochemistry methods and expression of CD10 was compared in two groups of benign thyroid lesions and PTC. Results: From selected cases 134 sections studied in two groups of PTC (n = 67 and benign thyroid lesions (n = 67. CD10 were immunohistochemically positive in 29.9% of PTC cases, but in none of the thyroid benign lesions (0% (P 0.05. Conclusion: The results of the current study indicate that due to the higher expression of CD10 in PTC than benign thyroid lesions it might be used for differentiating mentioned lesions. But for using it as a diagnostic tool further studies with larger sample size and determination of its sensitivity, specificity and cut-off point is necessary.

    2011-01-01

    Full Text Available OBJECTIVES: The aim of this study was to investigate the role of the interleukin-18 +105A/C and interleukin-10 -1082A/G germline polymorphisms in the development and outcome of differentiated thyroid carcinoma associated or not with concurrent thyroiditis. METHODS: We studied 346 patients with differentiated thyroid carcinomas, comprising 292 papillary carcinomas and 54 follicular carcinomas, who were followed up for 12-298 months (mean 76.10 ± 68.23 months according to a standard protocol. We genotyped 200 patients and 144 control individuals for the interleukin-18 +105A/C polymorphism, and we genotyped 183 patients and 137 controls for the interleukin-10 -1082A/G polymorphism. RESULTS: Interleukin-18 polymorphisms were not associated with chronic lymphocytic thyroiditis or any clinical or pathological feature of tumor aggressiveness. However, there was an association between the presence of interleukin-10 variants and chronic lymphocytic thyroiditis. Chronic lymphocytic thyroiditis was present in 21.74% of differentiated thyroid carcinoma patients, most frequently affecting women previously diagnosed with Hashimoto's thyroiditis who had received a lower 131I cumulative dose and did not present lymph node metastases. CONCLUSIONS: We conclude that the inheritance of a G allele at the interleukin-10 -1082A/G polymorphism may favor a concurrent thyroid autoimmunity in differentiated thyroid carcinoma patients, and this autoimmunity may favor a better prognosis for these patients.

    2012-04-01

    Full Text Available Abstract In the following report we discuss a very rare case of malignant T-cell lymphoma of the thyroid gland that developed in a 70-year-old woman with a past history of hypothyroidism due to chronic thyroiditis. The chief complaint was a rapidly growing neck mass. CT and ultrasonographic examination revealed a diffuse large thyroid gland without a nodule extending up to 13 cm. Although presence of abnormal lymphoid cells in the peripheral blood was not found, the sIL-2 Receptor antibody and thyroglobulin measured as high as 970 U/ml and 600 ng/mL respectively. Fine needle aspiration cytology diagnosed chronic thyroiditis. A preoperative diagnosis of suspicious malignant lymphoma of the thyroid gland accompanied by Hashimoto’s thyroiditis was made, and a right hemithyroidectomy was performed to definite diagnosis. Histological examination revealed diffuse small lymphocytic infiltration in the thyroid gland associated with Hashimoto’s thyroiditis. Immunohistochemical examination showed that the small lymphocytes were positive for T-cell markers with CD3 and CD45RO. The pathological diagnosis was chronic thyroiditis with atypical lymphocytes infiltration. However, Southern blot analysis of tumor specimens revealed only a monoclonal T-cell receptor gene rearrangement. Finally, peripheral T cell lymphoma was diagnosed. Therefore, the left hemithyroidectomy was also performed one month later. No adjuvant therapy was performed due to the tumor stage and its subtype. The patient is well with no recurrence or metastasis 22 months after the surgical removal of the thyroid. As malignant T-cell lymphoma of the thyroid gland with Hashimoto’s thyroiditis was difficult to diagnose, gene rearrangement examination needed to be performed concurrently.

    The reported relationship of radiation exposure and thyroid carcinoma stimulated this retrospective study of 298 patients treated at St. Jude Children's Hospital with radiation therapy to the neck for childhood cancer to identify patients who developed subsequent thyroid abnormalities. This series includes 153 patients with Hodgkin's disease, 95 with acute lymphocytic leukemia, 28 with lymphoepithelioma, and 22 with miscellaneous tumors. Inclusion in the study required 5 years of disease-free survival following therapy for their original tumor, which included thyroid irradiation. Follow-up has been 100%. Most patients also received chemotherapy. Seventeen patients were found to have decreased thyroid reserve with normal levels of free triiodothyroxine (T3) or free thyroxin, (T4) and an elevated level of thyroid-stimulating hormone (TSH). In nine patients hypothyroidism developed, with decreased T3 or T4 levels and an elevated level of TSH. One hyperthyroid patient was identified. Two patients had thyroiditis, and seven had thyroid neoplasms: (carcinoma in two, adenoma in two, colloid nodule in one, and undiagnosed nodules in two). This survey has demonstrated an increased incidence of thyroid dysfunction and thyroid neoplasia when compared to the general population. The importance of long-term follow-up for thyroid disease is emphasized in patients who have received thyroid irradiation. The possible role of subclinical hypothyroidism with TSH elevation coupled with radiation damage to the thyroid gland as a model for the development of neoplastic disease is discussed.

    Acute febrile neutrophilic dermatosis (AFND; Sweet syndrome) is characterized by a constellation of symptoms and findings: fever, neutrophilia, and tender erythematous skin lesions that typically show an upper dermal infiltrate of mature neutrophils. Whereas some cases are idiopathic, others have been associated with a variety of disorders. In this report, we describe the occurrence of AFND with chronic lymphocytic thyroiditis (Hashimoto thyroiditis) and preexisting psoriasis. This is the first case report of the association of chronic lymphocytic thyroiditis with AFND from the United States and only the third reported in the world's literature. Because the coexistence of these disorders is rare, an underlying common pathogenic mechanism is a possibility. We postulate this to be CD4(+) T-cell dysfunction.

    Graves' disease (GD) is an autoimmune disease that involves aberrant B and T lymphocyte responses. Detailed knowledge about lymphocyte subpopulation composition will therefore enhance our understanding of the pathogenesis of GD and might support the development of new immunomodulatory treatment approaches. The aim of this study was to gain detailed insight into the composition of the peripheral blood lymphocyte compartment in GD before and during anti-thyroid drug therapy. Major B and T lymphocyte subpopulations were investigated by flow cytometry in peripheral blood from newly diagnosed GD patients (n = 5), GD patients treated with anti-thyroid drugs (n = 4), patients with recurrent GD (n = 7) and healthy controls (HC; n = 10). In GD patients, numbers of activated T lymphocytes [human leucocyte antigen D-related (HLA-DR)+ and CD25+] were increased. The B lymphocyte compartment in GD was characterized by significantly higher numbers of transitional (CD38highCD27−, P < 0·03) and pre-naive mature (CD38lowCD27−IgD+CD5+, P < 0·04) B lymphocytes, while memory populations were slightly decreased. The increased numbers of CD5+, transitional and pre-naive mature B lymphocytes correlated positively with fT4 plasma levels. GD is associated with increased numbers of activated T lymphocytes and transitional and pre-naive mature CD5+ B lymphocytes within the peripheral blood. The increase in CD5+ B lymphocytes was due mainly to an increase in transitional and pre-naive mature B lymphocytes. Increased fT4 plasma levels might be associated with this increase in transitional and pre-naive mature CD5+ B lymphocytes. PMID:23901889

    2015-04-01

    Thyroid disorders include autoimmune thyroid diseases (AITD), thyroid goiter, nodule and cancer. AITD mainly consist of autoimmune thyroiditis and Graves disease. The common characteristic of thyroid disorders is female preponderance in their prevalence. The female-to-male rate ratio is reported at 4~6:1 for AITD and about 3~4:1 for thyroid nodule. For PTC, it is greatest during reproductive age and drops from five and more in patients aged 20-24, to 3.4 in patients aged 35-44 to one in patients over 80. The effects of female gonadal hormones and X chromosome inactivation on thyroid gland and immune system greatly contribute to the female predilection of AITD. The former mainly include prolactin and estrogen. The direct actions of estrogen on the thyroid tissue contribute to the development of thyroid goiter, nodule and cancer in women.

    Background: Thyroid nodules are a common clinical problem, and differentiated thyroid cancer is becoming increasingly prevalent. Since the American Thyroid Association's (ATA's) guidelines for the management of these disorders were revised in 2009, significant scientific advances have occurred in the field. The aim of these guidelines is to inform clinicians, patients, researchers, and health policy makers on published evidence relating to the diagnosis and management of thyroid nodules and differentiated thyroid cancer. Methods: The specific clinical questions addressed in these guidelines were based on prior versions of the guidelines, stakeholder input, and input of task force members. Task force panel members were educated on knowledge synthesis methods, including electronic database searching, review and selection of relevant citations, and critical appraisal of selected studies. Published English language articles on adults were eligible for inclusion. The American College of Physicians Guideline Grading System was used for critical appraisal of evidence and grading strength of recommendations for therapeutic interventions. We developed a similarly formatted system to appraise the quality of such studies and resultant recommendations. The guideline panel had complete editorial independence from the ATA. Competing interests of guideline task force members were regularly updated, managed, and communicated to the ATA and task force members. Results: The revised guidelines for the management of thyroid nodules include recommendations regarding initial evaluation, clinical and ultrasound criteria for fine-needle aspiration biopsy, interpretation of fine-needle aspiration biopsy results, use of molecular markers, and management of benign thyroid nodules. Recommendations regarding the initial management of thyroid cancer include those relating to screening for thyroid cancer, staging and risk assessment, surgical management, radioiodine remnant ablation and therapy

    Autoimmune thyroid diseases (AITD) encompass a number of conditions that have in common cellular and humoral responses targeting the thyroid gland. Interactions between susceptibility genes and environmental triggers are thought to initiate an autoimmune response to thyroid antigens leading to disease manifestation. Commencement of the disease in childhood leads to the presumption that genetics may have an important role in the causation of the disease. The present study was aimed at evaluating the human leucocyte antigen (HLA) encoded susceptibility to develop juvenile autoimmune thyroiditis (JAT) in patients from North India. We studied 48 consecutive patients of JAT along with 176 first-degree relatives for their thyroid function (FT4, TSH) and anti-thyroid peroxidase antibody status (AbTPO). HLA studies were carried out using serology for HLA-class I antigens and DNA analysis of HLA-class II alleles. The data were compared with a cohort of 308 ethnically matched healthy individuals. We observed overt hypothyroidism in 50% and AbTPO positivity in 70.8% of the index cases. Among the first-degree relatives, goitre was observed in 51.7%, thyroid dysfunction in 28.4% and AbTPO in 29.5% of individuals. Of the 37 relatives who underwent fine-needle aspiration cytology (FNAC), 60% had evidence of chronic lymphocytic thyroiditis (CLT). A strong positive association of HLA-DRB1*1404 was observed with the JAT (35.4%vs. 10.4%, chi2 = 19.8, Pc = 0.0001). We also observed a higher (72%, P = 0.03) paternal transmission of HLA-DRB1*1404 to affected offspring in comparison to unaffected offspring. HLA-DRB1*03 was also increased among JAT patients but did not reach statistical significance. These studies point towards an important role of immune modifying genes, such as HLA, in influencing susceptibility to juvenile-onset AITD.

    Full Text Available Abstract Background The objective of this study was to compare the utility of Thin-Prep (TP cytologic preparation with that of Cell Block (CB preparation in the diagnosis of thyroid lesions, mainly follicular epithelial lesions, by fine needle aspiration biopsy (FNAB. Feasibility of using the TP slides for immunocytochemical stains is also discussed. Methods A total of 126 consecutive cases of thyroid FNAB with TP slides and 128 consecutive cases of thyroid FNAB with CB slides were reviewed blindly by two cytopathologists. The presence of colloid, follicular cells, macrophages and lymphocytes/plasma cells were recorded and scored 0–4 on each case based on TP or CB slide review. The cytologic diagnoses were grouped as follows: cyst, colloid nodule, colloid nodule with cystic change, chronic thyroiditis, atypical/neoplastic and non-diagnostic. Results The TP slides had higher diagnostic rate than CB slides. The diagnostic yield was 68% of the TP slides whereas only 24% of the CB slides were diagnostic. Also, only 4 atypical/neoplastic lesions were diagnosed on the TP slides and the corresponding direct smears, while 5 cases of atypical/neoplastic lesions were diagnosed on the smears but could not be diagnosed on the corresponding CB slides. Additionally, the TP slides revealed cytologic features that were not observed on the direct traditional smears of the same case. Conclusion In thyroid FNAB cases, TP slide preparation is superior to CB slide preparation and is more likely to have greater cellularity for diagnosis and detect atypical/neoplastic thyroid lesions, particularly those of follicular cell origin. Furthermore, TP slides appear to detect helpful diagnostic cytologic features and should be considered complementary to, rather than replacing, direct smears.

  19. Thyroid dysfunction and subfertility.

    The thyroid hormones act on nearly every cell in the body. Moreover, the thyroid gland continuously interacts with the ovaries, and the thyroid hormones are involved in almost all phases of reproduction. Thyroid dysfunctions are relatively common among women of reproductive age, and can affect fertility in various ways, resulting in anovulatory cycles, high prolactin levels, and sex hormone imbalances. Undiagnosed and untreated thyroid disease can be a cause of subfertility. Subclinical hypothyroidism (SCH), also known as mild thyroid failure, is diagnosed when peripheral thyroid hormone levels are within the normal reference laboratory range, but serum thyroid-stimulating hormone levels are mildly elevated. Thyroid autoimmunity (TAI) is characterized by the presence of anti-thyroid antibodies, which include anti-thyroperoxidase and anti-thyroglobulin antibodies. SCH and TAI may remain latent, asymptomatic, or even undiagnosed for an extended period. It has also been demonstrated that controlled ovarian hyperstimulation has a significant impact on thyroid function, particularly in women with TAI. In the current review, we describe the interactions between thyroid dysfunctions and subfertility, as well as the proper work-up and management of thyroid dysfunctions in subfertile women.

    Full Text Available Aim. To investigate obstetric features of pregnant women with thyroid disorders and thyroid function tests of their newborn infants. Methods. Women with hypothyroidism and having anti-thyroglobulin (ATG and anti-thyroid peroxidase (anti-TPO antibodies were assigned as group I, women with hypothyroidism who did not have autoantibodies were assigned as group II, and women without thyroid problems were assigned as group III. Results. Pregnant women with autoimmune hypothyroidism (group I had more preterm delivery and their babies needed more frequent neonatal intensive care unit (NICU admission. In group I, one infant was diagnosed with compensated hypothyroidism and one infant had transient hyperthyrotropinemia. Five infants (23.8% in group II had thyroid-stimulating hormone (TSH levels >20 mIU/mL. Only two of them had TSH level >7 mIU/L at the 3rd postnatal week, and all had normal free T4 (FT4. Median maternal TSH level of these five infants with TSH >20 mIU/mL was 6.6 mIU/mL. In group III, six infants (6.5% had TSH levels above >20 mIU/mL at the 1st postnatal week. Conclusion. Infants of mothers with thyroid problems are more likely to have elevated TSH and higher recall rate on neonatal thyroid screening. Women with thyroid disorders and their newborn infants should be followed closely for both obstetrical problems and for thyroid dysfunction.

There were significant correlations between the positive expression of serum thyroid autoanti-body(TPOAb, TgAb) and Th1% as well as the Th1/Th2 ratio. It is concluded that the increase of Th1% and the imbalance of Th1/Th2 may play an important role in the occurrence and process of CLT, and that the detection of Th1/Th2 cells by flow cytometry can be recognized as a reliable way to study the immune state of autoimmune thyroiditis.

    Full Text Available A rare case of extra medullary plasmacytoma (EMP of thyroid gland in a 60 year old male, occurring against a background of Hashimoto′s thyroiditis is reported. The fine needle aspiration cytology (FNAC initially done as an outpatient procedure, showed atypical epithelial cells on a background of amyloid. Considering these findings we gave a diagnosis of medullary carcinoma. Histology of the total thyroidectomy specimen showed an extensive infiltration of neoplastic plasma cells against a background of Hashimoto′s thyroiditis, with a bizarre Hurthle cell change. Immunohistochemistry on the histology sections confirmed the diagnosis of solitary plasmacytoma of thyroid against a background of Hashimoto′s thyroiditis.

    Thyroid function disorders affect between 5% and 15% of patients treated with IFNα and RBV for chronic hepatitis C. Women and patients with thyroid peroxidase antibodies (TPOAb) found before the treatment are at risk of developing the disorders (46.1% vs. 5.4%). The spectrum of IFNα-induced thyroiditis (IIT) includes two groups. Disorders with an autoimmune background are: presence of thyroid autoantibodies without clinical disease, Hashimoto's disease and Graves' disease. The second group comprises diseases caused by the direct toxic effect of IFNα on the thyroid gland, i.e. destructive thyroiditis and non-autoimmune hypothyroidism. Thyroid diseases are not an absolute contraindication for IFNα and RBV therapy. In patients diagnosed with thyroid dysfunction, before the antiviral therapy it is necessary to achieve euthyreosis. Thyroid function disorders may occur at any moment of the therapy. The earliest have been observed in the 4th week of treatment, and the latest 12 months after its termination. During the therapy, in order to diagnose IIT early, it is recommended to determine TSH level every 2-3 months depending on the presence of TPOAb before the treatment. The diagnosis and treatment of thyroid function disorders should be conducted in co-operation with an endocrinologist.

  16. Metastatic colorectal cancer to a primary thyroid cancer

    2008-11-01

    Full Text Available Abstract Background Metastatic malignancy to the thyroid gland is generally uncommon due to an unfavourable local thyroid micro-environment which impairs the ability of metastatic cells to settle and thrive. Metastases to the thyroid gland have however been reported to occur occasionally particularly if there has been disruption to normal thyroid tissue architecture. Case presentation We report a patient with a history of surgically resected rectal adenocarcinoma who presents with a rising serum CEA level and an 18F-FDG PET scan positive thyroid nodule which was subsequently confirmed at surgery to be a focus of metastatic rectal adenocarcinoma within a primary poorly differentiated papillary thyroid carcinoma. Subsequent treatment involved right hemi-thyroidectomy, pulmonary wedge resection of oligometastatic metastatic colorectal cancer and chemotherapy. Conclusion Metastatic rectal carcinoma to the thyroid gland and in particular to a primary thyroid malignancy is rare and unusual. Prognosis is likely to be more dependent on underlying metastatic disease rather than the primary thyroid malignancy hence primary treatments should be tailored towards treating and controlling metastatic disease and less emphasis placed on the primary thyroid malignancy.

    Full Text Available Background: Considering that thyroid nodules and thyroid cancer occur more frequently in people chronically exposed to radiation, the aim of this study was to evaluate the prevalence of thyroid nodules in a population occupationally exposed to radiation in hospitals of Isfahan, Iran. Materials and Methods: In this case-control study, the prevalence of thyroid nodules in staff members occupationally exposed to radiation was determined by ultrasonography. The results were compared with the results of another study among the adult population of Isfahan which selected by cluster random sampling method. The 2 studied groups were matched according to sex and age. Results: The case and control groups included 124 and 471 persons, respectively. The prevalence of thyroid nodules in the case and control groups was 22.6% and 24.6%, respectively (p > 0.05. Although thyroid nodules were significantly more prevalent in females in the control group, no such difference was observed between females and males of the case group (p > 0.05. The number of thyroid nodules (single or multiple and calcification were not different between the two groups (p > 0.05. In addition, hypoechogenicity of thyroid nodules was not different between the two groups for (p > 0.05. Conclusion: In our study, there was not any correlation between chronic occupational exposure to low dose of radiation and the risk of developing thyroid nodules. Further studies with larger sample sizes, at different doses of radiation, and considering iodine status and thyroid function are thus required.

    Granular cell tumor (GCT) of the thyroid is rare. Before this report, only four cases of thyroid GCT have been reported, none of which presented a cytopathological examination. In this paper, we report the fine needle aspiration cytology and pathological analysis of a thyroid GCT from a 12-year-old girl who presented with a painless neck mass. The tumor cells were single, in syncytial clusters, or pseudofollicles, contained small round, oval, or spindle nuclei, indistinct nucleoli, and a large amount of grayish, granular fragile cytoplasm. The background contained granular debris and naked nuclei. A differential diagnosis of thyroid GCT with more frequent thyroid lesions containing cytoplasmic granules, including Hurthle cells, macrophages, follicular cells, and cells of black thyroid syndrome, was also performed.

    Full Text Available Thyroid neoplasms represent the most common malignancies of the endocrine system. They are known to occur in association with benign lesions of the thyroid, like multinodular goitre and Hashimoto thyroiditis. AIMS AND OBJECTIVES : To study the neoplasms of thyroid and their peritumoral morphology. MATERIALS AND METHODS : All thyroidectomy specimens received in the Department of Pathology, RRMCH over a period of three years from June 2011 to May 2014 were included in the study. Thyro idectomies for non - neoplastic lesions were also extensively sampled and morphologically studied, with focus on peritumoral morphology, in neoplasms. RESULTS : Of the one hundred and fifty four thyroidectomy specimens received over three years, one hundred a nd thirteen (73.4% were non - neoplastic, and forty one were neoplastic (26.6%. Colloid goitre and lymphocytic infiltrate were the most common features in the peritumoral thyroid tissue, followed by multinodular goitre . Hashimoto thyroiditis and Hurthle cell change were noted in 11.5% of cases. Tumors were multicentric in 11.5% of cases. Malignancy was detected in eight of the fifty nine thyroidectomies performed for multinodular goitre . Of the thirty four surgeries for Hashimoto thyroiditis, four were reported as malignant on histopathology. CONCLUSION : All thyroidectomies, including those operated for benign lesions, need to be extensively sampled and morphology studied due to the possibility of occult malignancy. Larger series need to be st udied to find a causal association between the two.

    Full Text Available Background. Diabetes mellitus and thyroid diseases are common endocrine disorders in the general population and found to exist simultaneously. This study aimed to establish the prevalence of thyroid dysfunction among Omani type 2 diabetics and its association with glycemic control. Methodology. A retrospective cross-sectional randomized primary and secondary care based study of 285 Omani type 2 diabetics, ≥ 30 years of age with known thyroid function. The following parameters were examined: age, sex, duration of diabetes, duration of thyroid disease, thyroid morphology, thyroid function, thyroid antibodies, and the mean glycated hemoglobin (mean HbA1C. The prevalence of thyroid dysfunction was compared to an independent control group of randomly selected healthy individuals with known thyroid function. Results. Thyroid dysfunction was found in 12.6% of the diabetic patients compared to 4.9% in the control group. The prevalence was higher among the diabetic females (86% compared to diabetic males (14%. The commonest thyroid dysfunction among diabetics was overt hypothyroidism (4.6%. Subclinical hypothyroidism was the commonest thyroid dysfunction seen in less controlled diabetics at a mean HbA1c of 7.8 (± 0.7. Conclusion. Screening for thyroid dysfunction in patients with type 2 diabetes mellitus should be routinely performed considering the higher prevalence of thyroid diseases in this group compared to the general population.

    Full Text Available The cardiovascular signs and symptoms of thyroid disease are some of the most clinically relevant findings that accompany both hyperthyroidism and hypothyroidism. On the basis of the understanding of the mechanisms of thyroid hormone action on the heart and cardiovascular system, it is possible to explain the changes in cardiac output, cardiac contractility, blood pressure and rhythm disturbances that result from thyroid dysfunction. In the present review will integrate what is known about the mechanisms of thyroid hormone action on the heart and the alterations in thyroid hormone metabolism that accompany chronic congestive heart failure.

  5. Transcriptome, methylome and genomic variations analysis of ectopic thyroid glands.

    Directory of Open Access Journals (Sweden)

    Rasha Abu-Khudir

    Full Text Available BACKGROUND: Congenital hypothyroidism from thyroid dysgenesis (CHTD is predominantly a sporadic disease characterized by defects in the differentiation, migration or growth of thyroid tissue. Of these defects, incomplete migration resulting in ectopic thyroid tissue is the most common (up to 80%. Germinal mutations in the thyroid-related transcription factors NKX2.1, FOXE1, PAX-8, and NKX2.5 have been identified in only 3% of patients with sporadic CHTD. Moreover, a survey of monozygotic twins yielded a discordance rate of 92%, suggesting that somatic events, genetic or epigenetic, probably play an important role in the etiology of CHTD. METHODOLOGY/PRINCIPAL FINDINGS: To assess the role of somatic genetic or epigenetic processes in CHTD, we analyzed gene expression, genome-wide methylation, and structural genome variations in normal versus ectopic thyroid tissue. In total, 1011 genes were more than two-fold induced or repressed. Expression array was validated by quantitative real-time RT-PCR for 100 genes. After correction for differences in thyroid activation state, 19 genes were exclusively associated with thyroid ectopy, among which genes involved in embryonic development (e.g. TXNIP and in the Wnt pathway (e.g. SFRP2 and FRZB were observed. None of the thyroid related transcription factors (FOXE1, HHEX, NKX2.1, NKX2.5 showed decreased expression, whereas PAX8 expression was associated with thyroid activation state. Finally, the expression profile was independent of promoter and CpG island methylation and of structural genome variations. CONCLUSIONS/SIGNIFICANCE: This is the first integrative molecular analysis of ectopic thyroid tissue. Ectopic thyroids show a differential gene expression compared to that of normal thyroids, although molecular basis could not be defined. Replication of this pilot study on a larger cohort could lead to unraveling the elusive cause of defective thyroid migration during embryogenesis.

  6. Interferon induced thyroiditis.

    2009-12-01

    Interferon-alpha (IFNalpha) is used for the treatment of various disorders, most notable chronic hepatitis C virus (HCV) infection. One of the commonest side effects of IFNalpha therapy is thyroiditis, with up to 40% of HCV patients on IFNalpha developing clinical or subclinical disease. In some cases interferon induced thyroiditis (IIT) may result in severe symptomatology necessitating discontinuation of therapy. IIT can manifest as clinical autoimmune thyroiditis, presenting with symptoms of classical Hashimoto's thyroiditis or Graves' disease, or as non-autoimmune thyroiditis. Non-autoimmune thyroiditis can manifest as destructive thyroiditis, with early thyrotoxicosis and later hypothyroidism, or as non-autoimmune hypothyroidism. While the epidemiology and clinical presentation of IIT have been well characterized the mechanisms causing IIT are still poorly understood. It is likely that the hepatitis C virus (HCV) itself plays a role in the disease, as the association between HCV infection and thyroiditis is well established. It is believed that IFNalpha induces thyroiditis by both immune stimulatory effects and by direct effects on the thyroid. Early detection and therapy of this condition are important in order to avoid complications of thyroid disease such as cardiac arrhythmias.

    Full Text Available Hashimoto thyroditis is an organ specific autoim-mune disorder. Initially described Hakaru Hash-imotoa century ago is now the most common cause of hypothyroidism in iodine sufficient are-as of the world. But still the pathogenesis is not fully understood. With higher incidence among female population HT develops as a result of in-teraction between the genetic factors and envi-ronmental factors in susceptible individuals. HT is associated with other autoimmune disorders. Now many variants of HT have been identified: classical form, fibrous variant, IgG4 variant, juve-nile form, hashitoxicosis and silent thyroiditis (sporadic or postpartum. All variants of HT are characterized by lympho-cytic infiltration, destruction and atropy of thyroid gland ultimately thyroid failure though each entity has specific other features. Clinically HT can also present as euthyroid or even hyperthyroid state with or without goiter. Diagnosis is based on the clinical features, demonstration of antibodies against thyroid antigen, sonography and cytological findings. Treatment is mainly supplementing Levothyroixin for correction of hypothyroidism. Surgery is reserved for patients with large goiter causing mechanical compression of cervical structures, painful HT and suspicion of malignancy.

    Thyroid hormones modulate every component of the cardiovascular system necessary for normal cardiovascular development and function. When cardiovascular disease is present, thyroid function tests are characteristically indicated to determine if overt thyroid disorders or even subclinical dysfunction exists. As hypothyroidism, hypertension, and cardiovascular disease all increase with advancing age, monitoring of thyroid-stimulating hormone, the most sensitive test for hypothyroidism, is important in this expanding segment of our population. A better understanding of the impact of thyroid hormonal status on cardiovascular physiology will enable health care providers to make decisions about thyroid hormone evaluation and therapy in concert with evaluating and treating hypertension and cardiovascular disease. The goal of this review is to access contemporary understanding of the effects of thyroid hormones on normal cardiovascular function and the potential role of overt and subclinical hypothyroidism and hyperthyroidism in a variety of cardiovascular diseases.

    2011-03-01

    Thyroid ultrasound is easy to perform due to the superficial location of the thyroid gland, but appropriate equipment is mandatory with a linear high frequency transducer (7.5 - 12) MHz. Some pathological aspects of the thyroid gland are easily diagnosed by ultrasound, like the enlargement of the thyroid volume (goiter) or the presence of nodules and cysts; while other aspects are more difficult and need more experience (diffuse changes in the structure, echogenicity and vascularization of the parenchyma, differential diagnosis of malignant nodules). Ultrasound has become the diagnostic procedure of choice in guidelines for the management of thyroid nodules; most structural abnormalities of the thyroid need evaluation and monitoring but not intervention. A good knowledge of the normal appearance of the thyroid gland is compulsory for an accurate ultrasound diagnosis.

    Full Text Available Aim: Hashimato thyroiditis also known as chronic lymphocytic thyroiditis or autoimmune thyroiditis is characterized by lymphocyte and plasma cell infiltration of thyroid follicles causing destruction and atrophy in thyroid tissue. Reports on coexistence of several HLA antigen types in Hashimoto thyroiditis may indicate genetic predisposition. Parvovirus B19 is a prevalent and single stranded DNA virus that can cause disease in humans. Parvovirus B 19 infection may be responsible for autoimmune disorders or trigger them. The aim of our study was to evaluate the relationship between Parvovirus B19 and Hashimato thyroiditis. Material and Method: Fifity patients with Hashimato thyroiditis that were admitted to our Internal Medicine outpatient clinic and thirty healthy subjects were included in this study.

    2012-01-01

    Full Text Available We present a case of Warthin-like papillary thyroid carcinoma in a 22-year-old woman and a review of the literature on the topic. The patient had the occasional discovery of a hypoechoic thyroid nodule of approximately 18 mm, characterized by irregular margins, hyperechoic spots, rich intra- and perilesional vascularization, and a suspicious enlarged right laterocervical lymph node. Fine-needle aspiration was performed for both lesions and the diagnosis of papillary thyroid carcinoma without lymph node involvement was made. The patient underwent thyroidectomy and central neck lymphadenectomy without complications. Histopathological examination suggested a Warthin-like papillary carcinoma of the thyroid gland, with all the removed lymph nodes being free of disease. The patient subsequently underwent iodine ablative therapy and she remains free of disease one year after surgery. Warthin-like papillary thyroid carcinoma is a recently described variant of papillary thyroid cancer that is frequently associated with lymphocytic thyroiditis. Morphologically, it resembles Warthin tumors of the salivary glands, with T and B lymphocytes infiltrating the stalks of papillae lined with oncocytic cells. Surgical and postoperative management is identical to that of classic differentiated thyroid cancer, while prognosis seems to be favourable.

    We sought to verify the prevalence of lymphocytic thyroiditis (LT) and Hashimoto's thyroiditis (HT) in autopsy materials. Cases examined between 2003 and 2007 at the Department of Pathology of Faculty of Medicine of São Paulo University were studied. Immunohistochemical analyses were conducted in selected cases to characterize the type of infiltrating mononuclear cells; in addition, we evaluated the frequency of apoptosis by TUNEL assay technique and caspase-3 immunostaining. Significant increase in overall thyroiditis frequency was observed in the present series when compared with the previous report (2.2978% vs. 0.0392%). Thyroiditis was more prevalent among older people. Selected cases of LT and HT (40 cases each) had their infiltrating lymphocytes characterized by immunohistochemical analyses. Both LT and HT showed similar immunostaining patterns for CD4, CD8, CD68, thus supporting a common pathophysiology mechanism and indicating that LT and HT should be considered different presentations of a same condition, that is, autoimmune thyroiditis. Moreover, apoptosis markers strongly evidenced that apoptosis was present in all studied cases. Our results demonstrated an impressive increase in the prevalence of thyroiditis during recent years and our data support that the terminology of autoimmune thyroiditis should be used to designate both LT and HT. This classification would facilitate comparison of prevalence data from different series and studies.

    Full Text Available Steven Lehrer, Sheryl Green, John A Martignetti, Kenneth E Rosenzweig Departments of Radiation Oncology and Genetics and Genomic Sciences, Icahn School of Medicine at Mount Sinai, New York, NY, USA Background: The risk of thyroid cancer is known to be slightly increased in women after treatment for breast cancer. In the current study, we analyzed the incidence of thyroid cancer and breast cancer in 50 US states and in the District of Columbia to ascertain how often these two diseases are associated. Methods: Data on the incidence of thyroid cancer were obtained from the Centers for Disease Control and Prevention and the National Cancer Institute and data on the incidence of breast cancer were from the American Cancer Society. Data on the average number of children per family with children and mean household income were sourced from the US Bureau of the Census and prevalence of obesity by state is determined from a paper published in 2010 on state-specific obesity prevalence among US adults by the Centers for Disease Control and Prevention. Results: There was a significant association between breast and thyroid cancer (P=0.002. Since the incidence of breast cancer increases with increasing income and obesity, while decreasing with parity, multiple linear regression was performed. Breast cancer incidence was significantly related to thyroid cancer incidence (β=0.271, P=0.039, inversely related to average number of children per family with children (β=-0.271, P=0.039, unrelated to adult obesity (β=0.134, P=0.369, and significantly related to family income (β=0.642, P<0.001. Conclusion: This study identifies an association between breast and thyroid cancer. The association suggests that unexplored breast-thyroid cancer susceptibility loci exist and warrant further study.

    2010-05-01

    Transgenic NOD.H-2h4 mice expressing TGF-beta under control of the thyroglobulin promoter were generated to assess the role of TGF-beta in the development of thyrocyte hyperplasia. In contrast to nontransgenic littermates, which develop lymphocytic spontaneous autoimmune thyroiditis (L-SAT), all TGF-beta transgenic (Tg) mice given NaI water for 2-7 mo developed thyroid lesions characterized by severe thyroid epithelial cell hyperplasia and proliferation, with fibrosis and less lymphocyte infiltration than in nontransgenic mice. Most Tg mice produced less anti-mouse thyroglobulin autoantibody than did wild type (WT) mice. T cells from Tg and WT mice were equivalent in their ability to induce L-SAT after transfer to SCID or TCRalpha(-/-) mice. WT lymphocytes could transfer experimental autoimmune thyroiditis or L-SAT to Tg mice, indicating that the transgenic environment did not prevent migration of lymphocytes to the thyroid. Thyroids of Tg mice had higher frequencies of Foxp3(+) regulatory T cells (Tregs) compared with nontransgenic WT mice. Transient depletion of Tregs by anti-CD25 resulted in increased infiltration of inflammatory cells into thyroids of transgenic mice. Treg depletion also resulted in increased anti-mouse thyroglobulin autoantibody responses and increased expression of IFN-gamma and IFN-gamma-inducible chemokines in thyroids of Tg mice. The results suggest that spontaneous autoimmune thyroiditis is inhibited in mice expressing transgenic TGF-beta on thyrocytes, at least in part, because there is an increased frequency of Tregs in their thyroids.

    Background: Low vitamin D status is associated with autoimmune thyroid disease. Oral vitamin D supplementation was found to reduce titers of thyroid antibodies in levothyroxine-treated women with postpartum thyroiditis and low vitamin D status. Methods: The study included 34 women with Hashimoto's thyroiditis and normal vitamin D status (serum 25-hydroxyvitamin D levels above 30 ng/mL) who had been treated for at least 6 months with levothyroxine. On the basis of patient preference, women were divided into 2 groups, receiving (n=18) or not receiving (n=16) oral vitamin D preparations (2000 IU daily). Serum levels of thyrotropin, free thyroxine, free triiodothyronine and 25-hydroxyvitamin D, as well as titers of thyroid peroxidase and thyroglobulin antibodies were measured at the beginning of the study and 6 months later. Results: There were no significant differences in baseline values between both study groups. 25-hydroxyvitamin D levels inversely correlated with titers of thyroid antibodies. No changes in hypothalamic-pituitary-thyroid axis activity and thyroid antibody titers were observed in vitamin-naïve patients. Vitamin D increased serum levels of 25-hydroxyvitamin D, as well as reduced titers of thyroid antibodies. This effect was more pronounced for thyroid peroxidase than for thyroglobulin antibodies and correlated with their baseline titers. Conclusions: Vitamin D preparations may reduce thyroid autoimmunity in levothyroxine-treated women with Hashimoto's thyroiditis and normal vitamin D status.

    Ectopic thyroid is a rare developmental anomaly with lingual thyroid accounting for majority of the cases. The presence of ectopic thyroid tissue lateral to the midline is very rare, and very few cases located in the submandibular region have been reported. The simultaneous finding of submandibular ectopic thyroid tissue and a functional orthotopic thyroid gland is even rarer. In the differential diagnosis of an ectopic submandibular thyroid, it is fundamental to exclude a metastasis from well-differentiated thyroid cancer, even when primary thyroid carcinoma is not demonstrable.

    Full Text Available FNAB (fine-needle aspiration biopsy is regarded as an important tool for diagnosing thyroid lesions because of its simplicity, safety and cost-effectiveness. Its role in correctly characterizing the group of indeterminate lesions or follicular-patterned neoplasms (FN might be more decisive. LBC (Liquid-based cytology is a technique based on the use of a semi-automated device that has gained popularity as a method of collecting and processing both gynecologic and non-gynecologic cytologic specimens. It achieves a diagnostic sensitivity as accurate as conventional preparations especially for its excellent cell preservation and for the lack of background which decrease the amount of inadequate diagnoses. Moreover, the cellular material which has been stored in the preservative solution could be effectively used for the application of immunocytochemical and molecular techniques used especially for the Follicular proliferations . In many cases the cytologic features are similar in both methods but the colloid film and the lymphocytic component are more easily evaluated on direct smears whereas nuclear details and colloid globules are better evaluated in LBC slides. The LBC processed biopsies represent a valid alternative to conventional cytology. The possibility of applying special techniques enhance the efficacy of the cytological diagnosis of thyroid lesions.

    Fine-needle aspiration biopsy is regarded as an important tool for diagnosing thyroid lesions because of its simplicity, safety, and cost-effectiveness. Its role in correctly characterizing the group of indeterminate lesions or follicular-patterned neoplasms (FN) might be more decisive. Liquid-based cytology (LBC) is a technique based on the use of a semi-automated device that has gained popularity as a method of collecting and processing both gynecologic and non-gynecologic cytologic specimens. It achieves a diagnostic sensitivity as accurate as conventional preparations especially for its excellent cell preservation and for the lack of background which decrease the amount of inadequate diagnoses. Moreover, the cellular material which has been stored in the preservative solution could be effectively used for the application of immunocytochemical and molecular techniques especially for the Follicular proliferations. In many cases the cytologic features are similar in both methods but the colloid film and the lymphocytic component are more easily evaluated on direct smears whereas nuclear details and colloid globules are better evaluated in LBC slides. The LBC-processed biopsies represent a valid alternative to conventional cytology. The possibility of applying special techniques enhance the efficacy of the cytological diagnosis of thyroid lesions.

    plus supplements, iodine intake from diet/kg body wt, and milk intake (P = 0.001 for all), but not urinary iodine excretion measured as a concentration (P = 0.40). All measures of iodine intake were significantly related to serum thyroglobulin concentration (P less than or equal to 0.002), but only...... excretion measured as a urinary concentration, predicted thyroid volume. Serum thyroglobulin concentration appears to be a good marker of iodine status. Subgroups with low intakes of milk and milk products had an increased risk of thyroid disease.......Background: Iodine intake can be measured in various ways, and each method may have advantages and disadvantages. Objective: We sought to investigate the potential associations of various measures of iodine intake with thyroid volume, prevalence of thyroid nodules, and serum thyroglobulin. We also...

    Full Text Available Background: Subacute thyroiditis is an important cause of thyrotoxicosis, often misdiagnosed as Graves’ disease and given anti-thyroid drugs. Etiological diagnosis can yield proper guideline of management and a good result. Objectives: To see the clinical, biochemical and isotope profile of subacute thyroiditis. Methods: A total of 45 cases [36 females, 9 males; age (mean ± SD: 33± 4.7 yr] were recruited from Endocrine outpatient department of Bangabandhu Sheikh Mujib Medical University (BSMMU to see thyroid hormones and isotope scan. Results: Most of the patients had a history of sore throat (84.4%. All had painful thyroid gland with or without dysphagia, palpitation (93%, fever (91%, sweating and heat intolerance (80% and IBS like symptoms was 46%. Among 36 females, 16 patients (44.4% presented with oligomenorrhea/amenorrhea. Clinically palpable thyromegaly was present in 33 cases (73%, which was diffuse in 24 patients (73%, resting tachycardia in 35(78% while anaemia in 23(51%. A few cases (13/45 had raised blood pressure. Elevation of thyroid hormone was found in 44(97.7%, but in most cases it was mild; little reduction of TSH (0.1-0.3mIU was present in 43 (95%. Characteristically, low radio-iodine uptake (< 5% in 2 hours and 24 hours was found in 100% and thyroid scan revealed uniform uptake in all cases. ESR was raised in 100% cases and leucocytosis was present in 9(20%. Conclusion: It is concluded that subacute thyroiditis can be diagnosed on careful clinical examination. As it is a self limiting disease and does not usually need any anti-thyroid medication, subacute thyroiditis should be excluded in thyrotoxic patients before initiating anti-thyroid drugs.

    2016-08-01

    Full Text Available BACKGROUND Multinodular goitre or nodular hyperplasia or adenomatoid goitre is the most common thyroid disease, which occurs due to deficient iodine intake. Initial hyperthyroid states, followed by follicular atrophy and secondary changes like haemorrhage, calcification and cystic degeneration occurs in most of the cases. Longstanding cases of nodular goitre can be associated with carcinomas, usually follicular carcinomas, and rarely papillary carcinomas.[1] This study was done to know the incidence of coexisting malignancies, follicular and papillary carcinomas of thyroid, in longstanding nodular goitres of thyroid. METHODS All the cases of nodular goitres examined in the last two years were studied, including the thyroidectomy specimens and FNAC slides whichever was done. Extensive grossing of the thyroidectomy specimens was done to detect the possibility of malignancy in longstanding cases of nodular goitre of thyroid. Review of FNAC slides was done in cases where cytodiagnosis of coexisting malignancy was missed and detected in histopathological examination. RESULTS In the present study, conducted over a two-year period, out of 50 cases of thyroidectomy specimens of multinodular goitres studied, six cases were diagnosed to be having coexisting malignancy of thyroid, of which four were follicular carcinomas of thyroid and two were papillary carcinomas of thyroid. FNAC diagnosis of coexisting malignancy was initially missed in FNAC in two cases, i.e. one case each of follicular carcinoma and papillary carcinoma. These FNAC slides were reviewed and the foci of malignancies detected. CONCLUSION There is a possibility of malignancy of thyroid coexisting with longstanding multinodular goitre of thyroid, which should be kept in mind, while performing the needle biopsy and thorough examination of FNAC slides is needed to avoid missing the possible detection of the coexisting malignant lesion. Thyroidectomy specimens should be extensively grossed to

    Background: Previous guidelines for the management of thyroid nodules and cancers were geared toward adults. Compared with thyroid neoplasms in adults, however, those in the pediatric population exhibit differences in pathophysiology, clinical presentation, and long-term outcomes. Furthermore, therapy that may be recommended for an adult may not be appropriate for a child who is at low risk for death but at higher risk for long-term harm from overly aggressive treatment. For these reasons, unique guidelines for children and adolescents with thyroid tumors are needed. Methods: A task force commissioned by the American Thyroid Association (ATA) developed a series of clinically relevant questions pertaining to the management of children with thyroid nodules and differentiated thyroid cancer (DTC). Using an extensive literature search, primarily focused on studies that included subjects ≤18 years of age, the task force identified and reviewed relevant articles through April 2014. Recommendations were made based upon scientific evidence and expert opinion and were graded using a modified schema from the United States Preventive Services Task Force. Results: These inaugural guidelines provide recommendations for the evaluation and management of thyroid nodules in children and adolescents, including the role and interpretation of ultrasound, fine-needle aspiration cytology, and the management of benign nodules. Recommendations for the evaluation, treatment, and follow-up of children and adolescents with DTC are outlined and include preoperative staging, surgical management, postoperative staging, the role of radioactive iodine therapy, and goals for thyrotropin suppression. Management algorithms are proposed and separate recommendations for papillary and follicular thyroid cancers are provided. Conclusions: In response to our charge as an independent task force appointed by the ATA, we developed recommendations based on scientific evidence and expert opinion for the

    Medullary thyroid carcinoma (MTC), which originates from thyroid parafollicular C cells, accounts for 3 to 5% of thyroid malignancies. MTC occurs either sporadically or in an inherited autosomal dominant manner. Hereditary MTC occurs as a familial MTC or as a part of multiple endocrine neoplasia (MEN) type 2A and B syndromes. A strong genotype-phenotype correlation has been observed between hereditary MTC and germ-line ?gain of function? mutations of the RET proto-oncogene. Most cases of pedi...

    Full Text Available Abstract Introduction We report the case of a patient diagnosed with a struma ovarii with lymphocytic thyroiditis of her ectopic thyroid tissue. We believe that this case presents an unusual variation of a struma ovarii and a rare presentation of subclinical hyperthyroidism. Case presentation A 17-year-old Caucasian female patient who had undergone an ovariectomy and been diagnosed with a struma ovarii was subsequently found to have persistent subclinical hyperthyroidism with a low radioiodine uptake. Abdominal magnetic resonance imaging and iodine-131 whole body scanning showed no residue or recurrence and a thyroid ultrasonography was normal. Laboratory and histopathological findings suggested Hashimoto's thyroiditis as the cause of the subclinical thyrotoxicosis, which had presumably started at the ectopic tissue. Conclusion Struma ovarii is a rare cause of thyrotoxicosis, and can be difficult to diagnose in the presence of co-existing thyroid disorders. In patients with a struma ovarii who have not undergone thyroidectomy, there is no common consensus on management in terms of residue, recurrence or metastasis. Autoimmune thyroiditis must be kept in mind for a differential diagnosis.

  17. The immunopathogenesis of chronic autoimmune thyroiditis one century after hashimoto.

    2013-01-01

    Hakaru Hashimoto described 4 patients with a hitherto unknown cause for goitre, struma lymphomatosa, a century ago. He was careful to distinguish this from Riedel thyroiditis but it has become clear that fibrosis and atrophy of the thyroid are indeed components of Hashimoto thyroiditis, and in rare cases IgG4-related sclerosing disease may be an outcome. Although the cause of the lymphocytic infiltration was unknown to Hashimoto, we now know through the pioneering studies of N.R. Rose and E. Witebsky [J Immunol 1956;76:417-427] that this condition is the archetype for autoimmune destruction as a disease mechanism. In the last two decades in particular, there has been huge interest in unravelling the genetic basis for this and related autoimmune disorders. The list of polymorphisms associated with autoimmune thyroid disease grows each year, and in the case of vitiligo, which is frequently found in association with thyroid autoimmunity, we know that 27 separate susceptibility loci account for less than 20% of the heritability of this condition. Environmental and existential factors may turn out to be just as complex in number and in interactions. We can thus imagine a 'Swiss cheese' model for the causation of autoimmune thyroid disease, in which the effects of cumulative weaknesses line up - like the holes in slices of cheese - to allow the catastrophic event of autoimmune destruction to occur.

    Surgically resected thyroid specimens were obtained from 18 patients who had received low-dose head and neck radiation during infancy or early childhood. Twelve of the eighteen patients had thyroid carcinoma, with six having lymph node metastases. In eight the malignancy was not found in the nodule that prompted the surgery but was discovered only after thorough examination of the entire specimen. Our patients showed a number of other histologic changes, not previously emphasized in the literature. They uniformly had marked multinodularity, extensive interstitial fibrosis, and in some cases lymphocytic thyroiditis.

    Introduction: To evaluate the computed tomographic (CT) findings of primary thyroid lymphoma. Methods and material: The clinicopathological data and CT images of nine patients with primary thyroid lymphoma were retrospectively reviewed. The CT appearances were classified into three types: type 1, a solitary nodule surrounded by normal thyroid tissue; type 2, multiple nodules in the thyroid, and type 3, a homogeneously enlarged both thyroid glands with a reduced attenuation with or without peripheral thin hyperattenuating thyroid tissue. Results: All patients had a rapidly enlarging thyroid mass and coexistent Hashimoto's thyroiditis. One patient showed type 1 pattern, three type 2, and five type 3. Six patients had homogeneous tumor isoattenuating to surrounding muscles. The tumors had a strong tendency to compress normal remnant thyroid and the surrounding structure without invasion. Conclusion: Primary thyroid lymphoma should be included in the differential diagnosis when old female had a homogeneous thyroidal mass isoattenuating to muscles, which does not invade surrounding structures.

    Aim: To evaluate the ultrasound (US) features of the diffuse sclerosing variant of papillary carcinoma (DSVPC) of the thyroid, with histopathological correlations. Materials and methods: The US and histopathological findings of six patients with surgically proven DSVPC of the thyroid were retrospectively assessed. Results: Most of cases showed diffuse, scattered microcalcifications with or without associated masses and underlying heterogeneous hypoechogenicity at the site of the DSVPC in the thyroid. At ultrasound, scattered microcalcifications and heterogeneous hypoechogenicity seen in the DSVPC correlated to psammoma bodies and lymphocytic infiltration at histopathological review. Conclusion: DSVPC of the thyroid usually manifested as diffuse scattered microcalcifications and associated suspicious mass on ultrasound. These findings are not specific for the DSVPC of the thyroid. However, in relatively young patients with suspicious masses associated with underlying diffuse scattered microcalcifications on US, the possibility of DSVPC should be included in differential diagnosis.

    Thyroid autoimmunity is the most common organ-specific autoimmune disorder, which is characterized by the production of thyroid autoantibodies and lymphocytic infiltration into the thyroid. The majority cases of chronic urticaria have unknown (idiopathic) causes, with about 30-40 % possibly having an autoimmune substrate. Considering that autoimmune factors may be the common features of both thyroid autoimmunity and urticaria, it is likely that both entities may coexist within the same patient. A number of studies have investigated the association between thyroid autoimmunity and urticaria. However, most of these studies are relatively small sample size, the power achieved in those studies was not sufficient to detect whether there is an association between urticaria and thyroid autoimmunity. The aim of this study is to combine primary data from all relevant studies to produce reliable estimates of the associations between thyroid autoantibodies and urticaria. Literature databases were searched including Medline, Embase, Web of Science, Chinese Wanfang, and CBM databases from January 1980 to December 2013. A total of 14,203 urticaria cases and 12,339 non-urticaria controls were included in this study. From these data, the odds ratio (OR) with 95% confidence interval (95% CI) was calculated. The meta-analysis results showed that the prevalence of positive thyroid autoantibodies in patients with urticaria was higher than non-urticaria controls (TgAb: OR 6.55, 95% CI 3.19-13.42, Purticaria were more likely to have thyroid autoimmunity than the control groups.

    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.

    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.

    2007-04-01

    Full Text Available Background: Fine-needle aspiration biopsy can very reliably discriminate between benign and malignant thyroid tumors. The role of additional intraoperative frozen section to guide intraoperative management was questioned.Methods: A retrospective analysis of all thyroid resections at our department between 2000 and 2004 was performed.Results: 420 patients with benign thyroid lesions underwent surgical resections. 169 lobectomies and 251 total thyroidectomies were performed and 57 (13.5 % thyroid cancers discovered (mostly papillary carcinomas. 54 frozen sections were performed and sensitivity rate of 11.1 % and specificity rate of 97.8 % was estimated.Conclusions: Our data supports the fact that intraoperative frozen section is not sensitive enough to substantially add to preoperative fine-needle aspiration biopsy, even with more selective use. We conclude that routine use of frozen section is not cost-effective in surgery of the benign thyroid and can therefore be abandoned.

    2013-02-01

    Full Text Available Background: Warthin tumor- like papillary carcinoma of thyroid is a rare variant of papillary thyroid carcinoma. It is characterized by distinct papillary structures lined by oncocytic tumor cells with nuclear features of papillary carcinoma and marked lymphoplasmocytic infiltrate in the papillary stalks. This tumor derives its name from its resemblance to Warthin tumor of major salivary glands.Case presentation: We report a 54- year- old man presented with bilateral thyroid masses. Histopathological study showed papillary structures lined by cells with eosinophilic granular cytoplasm and ground- glass nuclei with lymphoplasmacytic infiltration of the stalks.Conclusion: Warthin tumor-like papillary thyroid carcinoma could be mistaken for benign lymphoepithelial lesions such as Hashimoto thyroiditis, Hurthle cell tumors and tall cell variant of papillary carcinoma. Follow- up information on the previously reported cases has suggested that these tumors behave similarly to usual papillary carcinoma.

    FNAC has developed tremendous improvement in the diagnosis of thyroiditis. The present study was designed to asses the usefulness of FNAC to diagnose various types of thyroiditis and to study their smear patterns. Over a period of one-year, 70 cases of thyroiditis have been evaluated on the basis of cytomorphological criteria and clinical findings of patients. The age ranged from 12-60 years. Majority of the cases were between 21 to 30 years of age with female preponderance in each group of thyroiditis. Among 70 cases, 26(37.14%) cases were Hashimoto's thyroiditis, 21(30%) cases were lymphocytic thyroiditis, seven (10%) cases as granulomatous thyroiditis and 16(22.8%) were non-specific thyroiditis. Further study was carried out in these 70 cases regarding biochemical thyroid status, ultrasonography and radionucleotide scan. Blood was drawn from all patients for estimation of antibody titer to compare with cytological diagnosis. It was found that, clinical examination and history of patients had limited value in the diagnosis of thyroiditis. Ultrasonography and thyroid scan could not reliably differentiate between patients with autoimmune thyroiditis and those with simple and nodular goiter. Biochemically hypothyroidism is more frequently evaluated with Hashimoto's diseases. On the other hand, hyperthyroidism was observed in most other types of thyroiditis. Cytologically diagnosed 78.72% cases of autoimmune thyroiditis had positive antibody titer. From the present study it is concluded that FNAC is a safe, reliable, cost effective and time saving method in the diagnosis of thyroiditis. Being a benign condition also reduce the rate of unnecessary operation, which can be treated conservatively.

    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

    Full Text Available Abstract Background Limited data are available on the association between vitiligo and autoimmune thyroid disease in pediatric patients. In addition, reported studies of pediatric patients have been based on a population known to have vitiligo and subsequently evaluated for the presence of thyroid function abnormalities. Methods A retrospective chart review was performed on 333 children who had been followed for thyroid disorders by endocrinologists at the Yale Pediatric Thyroid Center over the last 5 years for autoimmune thyroid disease. Demographical and clinical features of patients found to have thyroid disease and vitiligo were recorded. These studies were approved by the Yale Human Investigation Committee. Results Of the total 333 children and adolescents, 9 (2.7% were noted to have vitiligo. Four patients (44% had Graves' disease and 5 patients (66% had Hashimoto's thyroiditis. For patients with Graves' disease and vitiligo, the average age of onset of thyroid disease was young at 4 ± 0.7 years, and the diagnosis of vitiligo usually preceded that of thyroid disease. For children with Hashimoto's thyroiditis and vitiligo, thyroid disease was diagnosed at an average age of 13.25 ± 2.8 years. Conclusion In our population, 4.6% of children with Graves' disease and 2.0% of children with Hashimoto's thyroiditis had vitiligo. Interestingly, when vitiligo presents with Graves' disease, it occurs in younger rather than older children.

    de Quervain thyroiditis is a self-limited inflammatory disorder of the thyroid gland. It is an uncommon disease in adults and very rare in children. Fritz de Quervain, a Swiss surgeon, who was an authority on thyroid disease, described the unique pathology of this disease. Granulomatous changes with giant cells in thyroid tissue are the pathological findings. Viral infection in genetically predisposed individuals has been proposed as the pathogenesis of the disease. Clinical hallmarks for the diagnosis are painful thyroid enlargement, elevated erythrocyte sedimentation rate, and C-reactive protein as well as decreased uptake of the thyroid gland on thyroid scintigraphy. In addition, thyrotoxicosis is present in about 50% of cases in early phase of the disease. Serum thyroglobulin level is usually elevated. Only symptomatic treatment with analgesics is usually required for pain relief. Glucocorticoid therapy may be used in severely ill patients. de Quervain thyroiditis is generally completely resolved without complications in 6-12 months. However, permanent hypothyroidism and recurrent disease have been reported in some patients.

    Thyroid nodules and thyroid abnormalities are common findings in the general population. Ultrasonography is the most important imaging tool for diagnosing thyroid disease. In the majority of cases a correct diagnosis can already be made in synopsis of the sonographic together with clinical findings and basal thyroid hormone parameters and an appropriate therapy can be initiated thereafter. A differentiation of hormonally active vs. inactive nodes, and in particular benign vs. malignant nodules is sonographically, however, not reliably possible. In this context, radioscanning has its clinical significance predominantly in diagnosing hormonal activity of thyroid nodules. Efforts of the past years aimed to improve sonographic risk stratification to predict malignancy of thyroid nodules through standardized diagnostic assessment of evaluated risk factors in order to select patients, who need further diagnostic work up. According to the "Breast Imaging Reporting and Data System" (BI-RADS), "Thyroid Imaging Reporting and Data Systems" (TI-RADS) giving standardized categories with rates of malignancy were evaluated as a basis for further clinical management. Recent technological developments, such as elastography, also showpromising data and could gain entrance into clinical practice. The ultrasound-guided fineneedle aspiration is the key element in the diagnosis of sonographically suspicious thyroid nodules and significantly contributes to the diagnosis of malignancy versus benignity.

    The topic "Thyroid and Radiation" is both an old and a new area to be solved by human beings. The thyroid is an organ that is usually susceptible to exposure to ionizing radiation, both by virtue of its ability to concentrate radioiodine (internal radiation) and by routine medical examination: Chest X-ray, Dental X-ray, X-irradiation of cervical lymphnodes etc. (external radiation). Iodine-131 is widely used for the therapy of Graves' disease and thyroid cancers, of which the disadvantage is radiation-induced hypothyroidism but not complications of thyroid tumor. The thyroid gland is comparatively radioresistant, however, the data obtained from Hiroshima, Nagasaki and Marshall islands indicates a high incidence of external radiation-induced thyroid tumors as well as hypothyroidism. The different biological effects of internal and external radiation remains to be further clarified. Interestingly, recent reports demonstrate the increased number of thyroid cancer in children around Chernobyl in Belarus. In this review, we would like to introduce the effect of radiation on the thyroid gland at the molecular, cellular and tissue levels. Furthermore the clinical usefulness of iodine-131, including the safety-control for radiation exposure will be discussed.

    Background Previous studies showed that the role of Fas ligand (FasL) is not consistent in the pathogenesis of autoimmune thyroiditis. This study was designed to investigate the effects of FasL on the pathogenesis of experimental autoimmune thyroiditis (EAT) using CMV-human FasL (hFasL) transgenic mice. Methods Transgenic mice ubiquitously expressing hFasL were used as an animal model of EAT by injection of porcine thyroglobulin (pTg). Expression of hFasL was detected by RT-PCR and Western blot. The activity of hFasL transgenic thyrocytes killing Jurket cells was determined. CMV-hFasL transgenic mice and wild type (WT) mice were immunized with pTg and killed 28 days later to evaluate the lymphocytic infiltration of their thyroids. The number of CD4+ and CD8+ lymphocytes from the spleen was detected using FACS. The serum interferon-γ (IFN-γ) concentration was measured by ELISA. Results hFasL expression in the thyroid of CMV-hFasL transgenic mice was confirmed. After co-incubation of Jurket thymocytes with thyroid tissues of CMV-hFasL transgenic mice, the percentage of apoptotic cells in the CMV-hFasL transgenic thyroid group was significantly higher than that of the control WT thyroid group [(23.4±4.3)% vs (6.6±2.5)%, P<0.01]. On day 28 after immunization with pTg, the infiltration index of lymphocytes in thyroids of the CMV-hFasL transgenic mice was significantly lower than that of the WT mice [(1.0±0.5) vs (2.1±0.7), P<0.001]. Moreover, the number of CD4+ and CD8+ lymphocytes of the spleen and serum IFN-γ concentration were significantly decreased in the CMV-hFasL transgenic mice. Conclusions FasL plays an important role in the pathogenesis of autoimmune thyroiditis. Transgenic mice ubiquitously expressing hFasL may strongly inhibit lymphocytic infiltration of the thyroid of EAT and ameliorate the course of this disease.

    Both environmental and genetic triggers factor into the etiology of autoimmune thyroid disease (AITD), including Graves' disease (GD) and Hashimoto's thyroiditis (HT). Although the exact pathogenesis and causative interaction between environment and genes are unknown, GD and HT share similar immune-mediated mechanisms of disease. They both are characterized by the production of thyroid autoantibodies and by thyroidal lymphocytic infiltration, despite being clinically distinct entities with thyrotoxicosis in GD and hypothyroidism in HT. Family and population studies confirm the strong genetic influence and inheritability in the development of AITD. AITD susceptibility genes can be categorized as either thyroid specific (Tg, TSHR) or immune-modulating (FOXP3, CD25, CD40, CTLA-4, HLA), with HLA-DR3 carrying the highest risk. Of the AITD susceptibility genes, FOXP3 and CD25 play critical roles in the establishment of peripheral tolerance while CD40, CTLA-4, and the HLA genes are pivotal for T lymphocyte activation and antigen presentation. Polymorphisms in these immune-modulating genes, in particular, significantly contribute to the predisposition for GD, HT and, unsurprisingly, other autoimmune diseases. Emerging evidence suggests that single nucleotide polymorphisms (SNPs) in the immunoregulatory genes may functionally hinder the proper development of central and peripheral tolerance and alter T cell interactions with antigen presenting cells (APCs) in the immunological synapse. Thus, susceptibility genes for AITD contribute directly to the key mechanism underlying the development of organ-specific autoimmunity, namely the breakdown in self-tolerance. Here we review the major immune-modulating genes that are associated with AITD and their potential functional effects on thyroidal immune dysregulation. Published by Elsevier Ltd.

    The heterogeneity of diagnostic criteria of Hashimoto's thyroiditis leads to overdiagnosis and prevents strong conclusions from being drawn in clinical studies. The aim of this study is to propose a comprehensive scoring system. A case-control study compared a set of presurgical features of patients with lymphocytic infiltration of the thyroid (Hashimoto's thyroiditis) and controls, in order to design a multi-criteria scoring system. Given a dichotomous outcome (lymphocytic infiltration of the thyroid), a set of covariates was analyzed in 180 patients after total thyroidectomy. A different validation cohort of 1,171 patients was reviewed and classified according to the score. Variables associated with the diagnosis of Hashimoto's thyroiditis were first assessed by univariate analysis. Analysis showed that TPOAb (area under the ROC curve (AUC), 0.67; 95 % CI 0.57-0.77) and TgAb (0.63; 95 % CI 0.54-0.74) were univariate predictors of the diagnosis of HT, which is largely recognized. Combined covariates were then tested using stepwise logistic regression analysis. The final regression model included TPOAb, TgAb, and thyroid vascularity (AUC 0.72; 95 % CI 0.62-0.81). A scoring system was developed, which has a sensitivity of 45.5 % and a specificity of 89.0 %, with a cutoff of 1.7. The likelihood of incident hypothyroidism was higher (OR 2.30; p = 0.004) in the positive (≥1.7) score group. A scoring system has a better performance than any single predictor and is able to identify the subgroup of individuals at higher risk to develop subsequent hypothyroidism.

    Full Text Available Abstract Background Thyroid gland derives from one median anlage at the base of the tongue, and from the two fourth branchial pouches. A number of anomalies may occur during their migration. These can be in form of ectopic tissues, which are frequently found along the course of thyroglossal duct and rarely in other sites, many of these may develop same diseases as the thyroid gland. Case presentation A 36-years-old female presented with a 3 month history of left side neck mass. The mass disappeared following aspiration of brown colored fluid, which on cytological examination showed cells with nuclear irregularities that warranted the resection of the lesion. The histology demonstrated a thyroid papillary carcinoma arising within the branchial cyst. Thereafter, the patient underwent a total thyroidectomy with central lymph nodes dissection. Histology showed a multifocal papillary carcinoma with central lymph nodes metastases. Only four cases of primary thyroid carcinomas in neck branchial cyst have been described so far. Conclusion In a lateral cystic neck mass, although rare, occurrence of ectopic thyroid tissue and presence of a papillary thyroid carcinoma should be kept in mind.

    The current prevalence of thyroid cancer in women is high. Likewise, other cancers and thyroid cancer have been based on the TNM classification system. Staging of thyroid cancer has an important role in determining the extent of surgical excision and lymph node dissection, planning the adjuvant therapy after surgery and predicting the recurrence rate and the prognosis of patients. Ultrasonography is the basic imaging modality to identify the tumor size and the extent of lymph node metastasis. More recently, computed tomography, magnetic resonance imaging and positron emission tomography provide additional help for the staging of thyroid cancer. So, this article describes the 7th edition of the TNM staging of thyroid cancer, as proposed by the American Joint Committee on Cancer, and the details of radiologic evaluation of the T, N and M stages

    Full Text Available Background: Endogenous hormones are critical to spermatogenesis and maintenance of male reproductive function. Follicle stimulating hormone (FSH, luteinizing hormone (LH, inhibin B and testosterone all serve important and well-known functions in the male hypothalamopituitary-gonadal axis and male reproduction. However, the potential relationship between other hormones, including thyroid hormones, and semen quality are still not completely understood. Thus in the present study an attempt has been made to report the degree of associations between thyroid hormones and semen quality. Methods: Fifty-five men were recruited from an infertility clinic between August 2010 to May 2011. Fresh semen samples were assessed for quality (concentration, motility and morphology and the serum levels of Tetraiodothyronine (T4, Triiodothyronine (T3, and Thyroid stimulation hormone (TSH were measured. Result & Conclusion: We have found that though men with abnormal semen profile had higher total T3, T4 concentrations and lower TSH concentrations compared to those with normal semen profile, only T4 showed significant increase and further it was found that only total T4 was significantly associated with asthenozoospermia. Further studies and observation are needed on a larger number of patients, to validate the correlation with Thyroid status and to justify the trial of a small dose of anti-thyroid drug in asthenozoospermic patients.

    Background. Pemphigus vulgaris is an autoimmune vesiculobullous disease, affecting the skin and mucous membranes. It is reported to be associated with other autoimmune diseases including autoimmune thyroid diseases. However we report herein a case of pemphigus vulgaris associated with autonomous toxic nodule. Case Presentation. A 51-year-old woman was evaluated for blisters and erosions that develop on her trunk, face, and extremities, with a five-year history of progressively enlarging neck mass, and a past medical history of pemphigus vulgaris seven years ago. The condition was associated with palpitation, dyspnea, and heat intolerance. Thyroid function tests and thyroid scan were compatible with the diagnosis of thyrotoxicosis due to autonomous toxic nodule. Exacerbation of pemphigus vulgaris was proved by skin biopsy from the patient which revealed histologic picture of pemphigus vulgaris. Conclusion. Autoimmune thyroid diseases are reported to associate pemphigus vulgaris. To our knowledge, this case is the first in the English literature to report association between pemphigus vulgaris and autonomous toxic nodule and highlights the possibility of occurrence of pemphigus vulgaris with a nonautoimmune thyroid disease raising the question: is it just a coincidence or is there an explanation for the occurrence of both conditions together?

    Neuromyelitis optica (NMO or Devic's syndrome) is a rare relapsing demyelinating disease of the central nervous system (CNS) that mainly affects the spinal cord and optic nerves and shares many clinical and radiological features with multiple sclerosis. The association of NMO with other autoimmune diseases was reported, but very few reports described association with autoimmune thyroid disease. Early differentiation between NMO and multiple sclerosis is very important as the natural course and treatment regimens differ significantly. We report a case of a 50-year-old woman who was admitted initially with vomiting, hiccups and paraesthesias but was not diagnosed with NMO and presented with a severe progression of the disease. The patient was also diagnosed to have autoimmune thyroiditis with lymphocytic infiltration of the thyroid which progressed from hyperthyroidism to hypothyroidism. NMO diagnosis was established with seropositivity for NMO-IgG and MRI showing longitudinally extensive spinal cord lesions (3 or more spinal segments). In spite of treatment, the response was poor due to lack of early diagnosis and aggressive immunosuppressant therapy.

    2014-01-01

    Haemorrhage after thyroid surgery is rare, but if it occurs it is a life-threatening condition necessitating emergency surgery. The aim of this study was to evaluate prevalence and risk factors of haemorrhage after thyroid surgery. A retrospective analysis was undertaken in a group of 8931 consecutive patients with various thyroid diseases treated in 2004-2013 at our institution. Potential risk factors for postoperative haemorrhage after thyroid surgery were analysed using logistic regression model. Haemorrhage after thyroid operation necessitating emergency surgery occurred in 40 (0.45%) of 8931 patients. None of the patients died within the perioperative period. Bleeding occurred within first 24 hours following surgery in 38 (95%) patients, and in the remaining 2 (5%) patients in more than 24 hours after initial surgery. The following risk factors for bleeding after thyroid operation were identified: male sex (OR 3.618; 1.762-7.430; p or = 70 years (OR 3.052; 1.275-7.304; p = 0.012), surgery for hyperthyroidism (OR 2.873; 1.511-5.462; p = 0.001), smoking (OR 2.855; 1.502-5.428; p = 0.001), subtotal thyroidectomy in contrast to total thyroidectomy or lobectomy (OR 2.853; 1.356-6.004; p=0.006), and thyroid operation undertaken by resident in training in general surgery (OR 2.596; 1.393-4.837; p = 0.003). Haemorrhage after thyroid operation necessitating emergency surgical intervention occurs most frequently within first 24 hour following surgery. Hence, for safety reasons a minimum of 24-hour hospital stay is recommended in all patients with risk factors for postoperative bleeding after thyroid operation. Quality monitoring of thyroid surgery should include also risk factors for postoperative bleeding.

    Full Text Available BACKGROUND Breast cancer is the most common malignant tumour in women worldwide. The relationship between breast cancer and thyroid disease is a controversy. Many of the studies showed hypothyroidism as the commonly found thyroid abnormality in breast cancer. [1] There is considerable evidence for an increased risk of thyroid and breast cancer in patients with iodine deficiency. This ability of iodine to reduce the risk of breast cancer is attributed to the ability of iodine and its compounds to induce apoptosis so that appropriate cell death occurs. Instead, in the absence of optimum level of iodine in the body the transformed cells continue to grow and divide resulting in cancer. AIMS 1. To find out the association of thyroid hormones and breast cancer in early breast cancer patients. 2. To find out the association of thyroid peroxidase antibodies in early breast cancer patients. Settings Cases: 82 breast cancer patients in early stage who attended the breast clinic. Controls: 82 age matched controls (Between 25-80 years. Design: Case control study. MATERIALS AND METHOD In this study, investigated for thyroid function test (T3, T4, TSH and thyroid peroxide antibody level in 82 early breast cancer patients. STATISTICAL ANALYSIS SPSS 16. RESULTS Statistically significant low T4 and high TSH in breast cancer patients, along with elevated thyroid peroxidase antibody. CONCLUSION Compared to hyperthyroidism, hypothyroidism was found to be clinically significant in breast cancer patients

    Full Text Available Background: Thyroiditis involves thyroid gland inflammation due to a wide variety of causes. The common varieties are subacute, silent and postpartum thyroiditis. Aims and Objectives: To retrospectively collect demographic data of thyroiditis from Bangalore over the past 5 years. Materials and Methods: Data were collected from three major nuclear medicine centers in Bangalore of the patients who came for technetium (Tc 99m pertechnetate scan of the thyroid. The diagnosis was based on the Tc 99 scan evidence of thyroiditis in these patients and biochemical evidence of thyrotoxicosis. Results: The total number of cases recorded were 2513. The females were more commonly affected compared with males with sex distribution of 1698 females and 815 females (2:1. The mean age of females was 32.5 ± 11.3 years whereas the mean age of males was 37.2 ± 12.4 years. The highest numbers of cases were recorded in the months of June and August. Conclusions: The females developed thyroiditis frequently and at an earlier age when compared with males. This data could give us an insight into the demographic pattern of thyroiditis in our country and may help in planning future preventive strategies.

    Full Text Available Background: Morphometrical evaluation of the larynx has always been interesting for both morphologists and the physicians. A good understanding of the anatomy and the knowledge of variations in the laryngeal cartilages is important Objective: Objective of the present study was to collect exact and reliable morphometric data of thyroid cartilage in adult human larynx of regional population. Methods: The totals of 50 thyroid cartilage specimens were studied. The cartilages were preserved in 5% formalin. The measurements were taken with the help of Digital Vernier Caliper. The cartilages were weighed on Single pan electronic balance. For each of the parameters, the mean, standard deviation (S.D. and range was calculated. Results: Mean depth of superior thyroid notch was 9.7± 3.36 mm. Asymmetry between the length of superior horn of thyroid cartilages in left and right sides can be seen, but difference was not statistically significant (p>0.05. It is observed that inner thyroid angle varies from 55 to 1040 and outer thyroid angle varies from 53 to 990. In present study mean weight of thyroid cartilage was 6.70±1.55 grams. Conclusions: A fair amount of intersubject variability in the dimensions was observed. Bilateral asymmetry, though present in majority of specimens, was insignificant. Various dimensions of thyroid cartilages are smaller as compared to the western population.

    Full Text Available Background: Recently, VE1, a monoclonal antibody against the BRAFV600E mutant protein, has been investigated in terms of its detection of the BRAFV600E mutation. Although VE1 immunostaining and molecular methods used to assess papillary thyroid carcinoma in surgical specimens are in good agreement, evaluation of VE1 in thyroid cytology samples is rarely performed, and its diagnostic value in cytology has not been well established. In present study, we explored VE1 immunoexpression in cytology samples from ex vivo papillary thyroid carcinoma specimens in order to minimize limitations of low cellularity and sampling/targeting errors originated from thyroid fineneedle aspiration and compared our results with those obtained using the corresponding papillary thyroid carcinoma tissues. Methods: The VE1 antibody was evaluated in 21 cases of thyroid cytology obtained directly from ex vivo thyroid specimens. VE1 immunostaining was performed using liquid-based cytology, and the results were compared with those obtained using the corresponding tissues. Results: Of 21 cases, 19 classic papillary thyroid carcinomas had BRAFV600E mutations, whereas two follicular variants expressed wild-type BRAF. VE1 immunoexpression varied according to specimen type. In detection of the BRAFV600E mutation, VE1 immunostaining of the surgical specimen exhibited 100% sensitivity and 100% specificity, whereas VE1 immunostaining of the cytology specimen exhibited only 94.7% sensitivity and 0% specificity. Conclusions: Our data suggest that VE1 immunostaining of a cytology specimen is less specific than that of a surgical specimen for detection of the BRAFV600E mutation, and that VE1 immunostaining of a cytology specimen should be further evaluated and optimized for clinical use.

    A deceased 59-year-old woman with insulin dependent diabetes mellitus complicated by chronic thyroiditis and chronic hepatitis was autopsied. She had had diabetes mellitus since she was 30 years old, and insulin therapy was started at 34 years. Laboratory findings were as follows: s-GOT 85, s-GPT 31, gamma-globulin 2.45 g/dl. Immunological tests were positive for anti-smooth muscle antibody and anti-ENA antibody with high titers of antithyroglobulin and anti-microsome antibodies. HLA analysis revealed the presence of DR-4. The thyroid biopsy specimen showed microscopic features characteristic of chronic thyroiditis at 52 years of age. She had been repeatedly admitted for the control of diabetes mellitus. She was admitted for the 9th time in June, 1987 following complaints of abdominal pain. After admission, her general condition became gradually worse, and she died of peritonitis in September, 1987. Pathological examination of the liver revealed an expansion of fibrous tissue on Glisson's capsule accompanied by lymphocytic infiltration and was diagnosed to be chronic inactive hepatitis. As for the thyroid gland, fibrous tissue replaced an extensive area of the thyroid gland, and normal thyroid tissue was not observed. Lymphocytic infiltration was less in comparison with that in the previous biopsy. As for the pancreas, atrophy of exocrine pancreatic tissue and fibrous change in interstitial tissue was observed. Lymphocytic infiltration was also seen in the interstitial exocrine tissue but not in the islet. Immunohistochemical examination of the islets using anti-insulin, glucagon and somatostatin antibodies by ABC peroxidase method showed the selective disappearance of B cells in the islets. The pathological changes in the thyroid gland, liver and pancreas suggest that autoimmune mechanism may be involved in the pathogenesis of chronic thyroiditis, chronic hepatitis and IDDM with exocrine pancreatic impairment in this case.

    Ultrasound examination of the thyroid offers an accurate morphological picture and the possibility of comparing objectively the size of lobes and lesions over long periods. Cysts and calcifications, mostly benign, are readily recognized. Neoplastic lesions in our series were all less reflective than normal thyroid tissue. But so were the majority of benign nodules. In hyperthyroidism, subacute thyroiditis and Hashimoto's thyroiditis, the thyroid tissue is much less echogenic than in the normal gland.

    Resistance to thyroid hormone (RTH) represents a syndrome in which patients present elevated circulating thyroid hormones in the presence of non-suppressed TSH. We report a novel case where a patient with RTH presented a differentiated thyroid cancer. A19 year-old female had been referred due to thyroid disease that disclosed features characteristic of a RTH. During the follow up it was detected a follicular tumor that led to the recommendation for thyroid surgical ablation, where an incidental papillary thyroid microcarcinoma (mPTC) was found. The increase of thyroglobulin (TG) levels following thyroid removal referred the patient for radioiodine treatment. Post-treatment, it was detected jugular adenopathies and the patient was subjected to cervical lymph node drainage where metastases of the mPTC were found. RTH syndrome was confirmed by the detection of a THRB germline mutation. A BRAF mutation was also found in the mPTC but not detected in the follicular adenoma or normal adjacent tissue. The young age of the patient, the rarity of BRAF mutations in childhood and the high dissemination of the malignancy, lead us to the speculation that increased TSH stimulation in a RTH background and oncogenic activation of BRAF could have served as (co) drivers and might have triggered an advanced stage of the neoplastic disease. These findings together with a review of published cases add novel information to the management of RTH patients with differentiated thyroid cancer.

    Full Text Available Background: Thyroid nodules are solid or cystic lumps within the thyroid gland. The purpose of this study was to evaluate the concordance between thyroid nodules ultrasound reports, based on Thyroid Imaging Reporting and Data (TIRAD System and results of ultrasound guided Fine Needle Aspiration (FNA. Methods: In this cross-sectional study, 144 patients with thyroid nodules who referred to the radiology department of Imam Reza Hospital of Kermanshah at the request of endocrinologist were evaluated. Data were analyzed by SPSS-21software using descriptive statistics. Results: The age range of patients was 15 to 78, with mean age 44.86±13.27 years. Of the sample, 141 cases (97.9 % were female and 3 cases (2.1 % were male. Based on the results of pathology, 130 (90.2% were benign and 14 (9.8% were malignant lesions and sonography result 129 cases (89.6% were benign and 15 cases (10.4% were malignant. There was a significant difference between the results of sonography and FNA and Kappa agreement test showed a significant concordance (96% between the sonographic reports of thyroid nodules, based on TIRAD system, and pathological findings. Conclusion: The results of this study indicated a high concordance between sonographic reports of thyroid nodules, based on TIRAD category, and FNA findings. Thus, TIRAD-based ultrasound can play a key role in determining thyroid nodules, thereby facilitating patient's management.

    Full Text Available OBJECTIVE: Primary thyroid lymphoma (PTL is an uncommon thyroid malignancy. Despite the rarity of PTL, it is important to recognize PTL promptly because its management differs from that of all the other thyroid neoplasms. This study was designed to investigate the sonographic features of PTL. METHODS: Twenty-seven pathologically confirmed PTLs were categorized into diffuse and non-diffuse type. Sonographic features including thyroid size, thyroid background echotexture, lesion size, echogenecity, calcification, vascularity, cervical lymphadenopathy of each type were retrospectively analyzed. RESULTS: All 27 PTLs were diffuse large B-cell lymphomas and were accompanied by diffuse Hashimoto's thyroiditis. Ten were diffuse type and seventeen were non-diffuse type sonographically. The observations in diffuse group included goiter (10/10, 100.0%, marked echogenesity (10/10, 100.0%, heterogeneous echotexture (10/10, 100.0%, and cervical lymphadenopathy (4/10, 40.0%. The observations in non-diffuse group included marked hypoechogenicity (17/17, 100.0%, heterogeneous background thyroid gland (17/17, 100.0%, goiter (15/17, 88.2%, increased vascularity (8/13, 61.5%, mulifocality (10/17, 58.8%, and cervical lymphadenopathy (7/17, 41.2%. CONCLUSIONS: Although some common features were found, the sonographic appearance of PTL is unspecific, especially for the diffuse type. Therefore, interventional diagnostic procedures should be warranted in the clinical settings when PTL is suspected.

    Thyroid hormone deficiency can have important repercussions. Treatment with thyroid hormone in replacement doses is essential in patients with hypothyroidism. In this review, we critically discuss the thyroid hormone formulations that are available and approaches to correct replacement therapy with thyroid hormone in primary and central hypothyroidism in different periods of life such as pregnancy, birth, infancy, childhood, and adolescence as well as in adult patients, the elderly, and in patients with comorbidities. Despite the frequent and long term use of l-T4, several studies have documented frequent under- and overtreatment during replacement therapy in hypothyroid patients. We assess the factors determining l-T4 requirements (sex, age, gender, menstrual status, body weight, and lean body mass), the major causes of failure to achieve optimal serum TSH levels in undertreated patients (poor patient compliance, timing of l-T4 administration, interferences with absorption, gastrointestinal diseases, and drugs), and the adverse consequences of unintentional TSH suppression in overtreated patients. Opinions differ regarding the treatment of mild thyroid hormone deficiency, and we examine the recent evidence favoring treatment of this condition. New data suggesting that combined therapy with T3 and T4 could be indicated in some patients with hypothyroidism are assessed, and the indications for TSH suppression with l-T4 in patients with euthyroid multinodular goiter and in those with differentiated thyroid cancer are reviewed. Lastly, we address the potential use of thyroid hormones or their analogs in obese patients and in severe cardiac diseases, dyslipidemia, and nonthyroidal illnesses.

    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.

MATERIALS AND METHODS This is a prospective study of cases referred to Balaji Diagnostics and Research Centre & Shadan Institute of Medical sciencesHyderabad for FNAC during March 2012 to February 2014. RESULTS This study consisted of 200 cases. Benign category was the largest (85% followed by ND/UNS category (6%, malignant and SFM category constituted 2% and 3% making a total of 5%, AUS/FLUS constituted 3% cases and FN/SFN had 1%. In ND/UNS category, all cases came under subcategory cyst fluid only. There was no case in other subcategories. In benign category, 140 cases had consistency with benign follicular nodule, 26 cases had consistency with lymphocytic thyroiditis, 2 each were having consistency with granulomatous thyroiditis. AUS/FLUS had constituted only 3% of 200 cases and FN/SFN had constituted only 1% of 200 cases. Under SFM category, 4 cases were suspicious of papillary carcinoma, 1 each suspicious of lymphoma and other related diseases. Under malignant category, papillary thyroid carcinoma constituted 3 cases and 1 case of medullary carcinoma. CONCLUSION Bethesda is an excellent reporting system for thyroid FNA. It also provides clear management guidelines to clinicians to go for followup FNA or surgery and also the extent of surgery.

    The aim of this study was to evaluate the frequency of chromosomal abnormalities in thyroid cancer patients before and after radioactive iodine administration in order to assess cytogenetic particularity in Polynesian thyroid cancer patients. Chromosomal abnormalities were studied in 30 Polynesian patients with differentiated thyroid cancer, prior to and 4 days after{sup 131}I administration. Unstable chromosomal abnormalities were counted in peripheral blood lymphocytes using a conventional cytogenetic method. Peripheral blood was irradiated in vitro at different doses (0.5, 1 and 2 Gy) in order to establish the dose-response of the lymphocytes. Control groups were composed of 50 European thyroid cancer patients before and after first administration of{sup 131}I, and of ten European healthy donors. In addition, in vitro irradiation assays were performed at different doses (0.5, 1 and 2 Gy). The relative risk of spontaneous dicentrics before any radiation treatment was 2.9 (95% CI 1.7-5.1) times higher among Polynesian thyroid patients than among European thyroid cancer patients. After in vitro irradiation, the rise in frequency of dicentrics was similar in the Polynesian thyroid cancer group and the European thyroid patients and healthy donors. Four days after administration of 3.7 GBq{sup 131}I, the relative risk for a dicentric per cell was 1.3 (95% CI 1.0-1.5) times higher in Polynesian than in European patients. This can be explained by higher{sup 131}I retention in Polynesian compared with European patients. The results obtained revealed an increased frequency of cytogenetic abnormalities in Polynesian thyroid cancer patients compared with European control patients. These preliminary findings are compatible with possible previous environmental aggression and therefore imply a need for further investigations on larger series including, in particular, French Polynesian healthy donors. In addition to French Polynesians, Maori and Hawaiian control groups could be

    Primary thyroid lymphoma (PTL) is a rare thyroid malignancy. Clinical diagnosis of PTL may not be easily established based on imaging studies, as the imaging features of PTL are similar to those of lymphocytic thyroiditis and primary thyroid cancer. The present study describes the case of a patient who was confirmed to have PTL by intra-operative pathological diagnosis. On color Doppler ultrasound, the PTL was shown as a significantly enlarged thyroid with reduced gland echoes. Color Doppler flow imaging showed increased blood flow. By computed tomography, the thyroid was revealed to be enlarged with reduced tissue density, particularly in the left lobe and the isthmus. In addition, calcified spots and swollen lymph nodes were evident. The clinical history of the patient was obtained and the imaging results were retrospectively analyzed. The imaging features of PTL were investigated through reviewing the literature. PTL exhibits specific features on medical imaging that aid in distinguishing it from other thyroid diseases. PTL exhibits specific features on medical imaging that aid in distinguishing PTL from other thyroid diseases, which may aid the support for clinical diagnosis and improve the clinical accuracy.

    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. PMID:28029020

Fungal thyroiditis is a rare occurrence owing to unique features of the thyroid gland. Most cases are caused by Aspergillus species and have been described in immunocompromised patients. Presentation may be identical with that of subacute thyroiditis, in which hyperthyroidism features and painful thyroid are the prominent findings. Diagnosis can be ascertained by fine-needle aspiration of thyroid showing branching hyphae of Aspergillus. We describe a renal transplant patient who developed Aspergillus thyroiditis as part of a disseminated infection successfully treated with voriconazole.

    Full Text Available Background: Subclinical thyroid disorders usually do not produce symptoms of thyroid disease until they turn into over thyroid disease. Thyroid disease is more common in people with diabetes mellitus than in the general population and it is important to detect thyroid disorder before its clinical manifestation. Subclinical hypothyroidism (SCH can produce dyslipidemia, obesity thus resulting increased predisposition to coronary artery disease. Subclinical hyperthyroidism can aggravate hyperglycemia and impair blood sugar control. Objectives: Our objective is to determine the prevalence of subclinical thyroid disorders in patients with type 2 diabetes mellitus (T2DM and to analyze the clinical and metabolic profile of patients with this dual endocrine disorder. Methods and Results: One hundred consecutive type 2 diabetic patients without clinical manifestations of thyroid disorders were screened for SCH and subclinical hyperthyroidism using serum free T 3 , free T 4 and thyroid stimulating hormone (TSH levels. Individuals of subclinical thyroid disease were further screened for thyroperoxidase (TPO antibodies. SCH was detected in 13% of type 2 diabetic patients and none had subclinical hyperthyroidism in our study. SCH was common among females with type 2 diabetes (84.6%. Elevated TPO antibody levels were present in 84.6% SCH patients. Diabetic retinopathy among SCH patients showed significant association with higher serum TSH levels. Left ventricular diastolic dysfunction was present in 30.8% of SCH patients. Conclusion: SCH is common among type 2 diabetic patients, especially in females. It is most commonly secondary to autoimmune thyroid disease. Microvascular complications are commonly observed in this group of patients with dual endocrinal disorder and treating physician should be aware of the impact and should routinely screen SCH to prevent complications.

    Thyroid hormones are crucial for organismal development and homeostasis. In humans, untreated congenital hypothyroidism due to thyroid agenesis inevitably leads to cretinism, which comprises irreversible brain dysfunction and dwarfism. Elucidating how the thyroid gland - the only source of thyroid hormones in the body - develops is thus key for understanding and treating thyroid dysgenesis, and for generating thyroid cells in vitro that might be used for cell-based therapies. Here, we review the principal mechanisms involved in thyroid organogenesis and functional differentiation, highlighting how the thyroid forerunner evolved from the endostyle in protochordates to the endocrine gland found in vertebrates. New findings on the specification and fate decisions of thyroid progenitors, and the morphogenesis of precursor cells into hormone-producing follicular units, are also discussed. © 2017.

  20. Chemokines, lymphocytes, and HIV

    Full Text Available Chemokines are members of a family of more than 30 human cytokines whose best-described activities are as chemotactic factors for leukocytes and that are presumed to be important in leukocyte recruitment and trafficking. While many chemokines can act on lymphocytes, the roles of chemokines and their receptors in lymphocyte biology are poorly understood. The recent discoveries that chemokines can suppress infection by HIV-1 and that chemokine receptors serve, along with CD4, as obligate co-receptors for HIV-1 entry have lent urgency to studies on the relationships between chemokines and lymphocytes. My laboratory has characterized Mig and Crg-2/IP-10, chemokines that are induced by IFN-g and that specifically target lymphocytes, particularly activated T cells. We have demonstrated that the genes for these chemokines are widely expressed during experimental infections in mice with protozoan and viral pathogens, but that the patterns of mig and crg-2 expression differed, suggesting non-redundant roles in vivo. Our related studies to identify new chemokine receptors from activated lymphocytes resulted in the cloning of STRL22 and STRL33. We and others have shown that STRL22 is a receptor for the CC chemokine MIP-3a, and STRL22 has been re-named CCR6. Although STRL33 remains an orphan receptor, we have shown that it can function as a co-receptor for HIV-1 envelope glycoproteins, and that it is active with a broader range of HIV-1 envelope glycoproteins than the major co-receptors described to date. The ability of STRL33 to function with a wide variety of envelope glycoproteins may become particularly important if therapies are instituted to block other specific co-receptors. We presume that investigations into the roles of chemokines and their receptors in lymphocyte biology will provide information important for understanding the pathogenesis of AIDS and for manipulating immune and inflammatory responses for clinical benefit

    Full Text Available Abstract Background Papillary thyroid microcarcinomas are tumors often found accidentally after thyroidectomy for other thyroid disorders. Methods Patients with enlarged lateral cervical masses, with unknown thyroid disease, found to have metastases from papillary thyroid carcinoma ≤10 mm in diameter, were compared to patients operated on for nodular or multinodular goiter, who were incidentally found to have papillary thyroid microcarcinomas. Results Group A included 24 patients with an enlarged lateral cervical mass whereas group B included 30 patients presenting with nodular or multinodular goiter. Patients in both groups underwent surgery. After thyroidectomy and lymph node dissection, pathology revealed multifocal papillary carcinomas of 1–10 mm, with invasion of the thyroid capsule and surrounding soft tissue in most of the cases in group A. Two patients presented with distant metastases at diagnosis which were surgically removed. During follow up, 3 patients (12.5% presented with new cervical metastases which were surgically removed or treated with additional radioactive iodine. At last follow-up, all patients were alive. In contrast, all patients in group B had unifocal papillary thyroid carcinoma 1–10 mm in maximum diameter, with no infiltration or extension into the adjacent tissue, or cervical lymph node metastases. Conclusion Two groups of papillary thyroid microcarcinomas characterized by different clinical and biological behaviours are identified. Significant differences were found between these groups concerning the age, tumor size, number of tumor foci, lymph nodes metastases and extrathyroidal extension of the tumor. Papillary thyroid carcinomas of small (≤10 mm size may have aggressive behaviour or be metastatic, and this subgroup should be treated and followed up as are other large, differentiated thyroid cancers.

    Full Text Available Male reproduction is governed by the classical hypothalamo-hypophyseal testicular axis: Hypothalamic gonadotropin releasing hormone (GnRH, pituitary luteinizing hormone (LH and follicle stimulating hormone (FSH and the gonadal steroid, principally, testosterone. Thyroid hormones have been shown to exert a modulatory influence on this axis and consequently the sexual and spermatogenic function of man. This review will examine the modulatory influence of thyroid hormones on male reproduction.

    AIM: To investigate some possible etiologies of achalasia by screening patients with achalasia for some autoimmune diseases such as thyroid disease.METHODS: We examined 30 known cases of achalasia (20 females, 10 males). Their age ranged 15-70 years.All of them were referred to our institute for treatment.Their sera were evaluated to detect some possible associations with rheumatoid disease, thyroid disease,inflammatory process, anemia, etc.RESULTS: Seven out of 30 patients (23%) had thyroid disease including four patients with hypothyroidism (13.3%), two patients with hyperthyroidism (6.6%),and one had only thyroid nodule but was in euthyroid state (3.3%). Two of these hypothyroid patients had no related clinical symptoms (subclinical) and two had clinical manifestations of hypothyroidism. There were no correlations between the intensity of thyroid diseases and the severity of achalasia symptoms.CONCLUSION: The etiology of achalasia is unknown although autoimmunity has been implicated and is supported by several studies. Thyroid disease presents concomitantly with achalasia in about one fourth of our patients who may have a common etiology.

    Full Text Available Abstract Background Incidentally found thyroid lesions are frequently detected in patients undergoing FDG-PET/CT. The aim of this study was to investigate the prevalence of incidentally found thyroid lesions in patients undergoing FDG-PET/CT and determine the risk for thyroid cancer. Methods FDG-PET/CT was performed on 3,379 patients for evaluation of suspected or known cancer or cancer screening without any history of thyroid cancer between November 2003 and December 2005. Medical records related to the FDG-PET/CT findings including maximum SUV(SUVmax and pattern of FDG uptake, US findings, FNA, histopathology received by operation were reviewed retrospectively. Results Two hundred eighty five patients (8.4% were identified to have FDG uptake on FDG-PET/CT. 99 patients with focal or diffuse FDG uptake underwent further evaluation. The cancer risk of incidentally found thyroid lesions on FDG-PET/CT was 23.2% (22/99 and the cancer risks associated with focal and diffuse FDG uptake were 30.9% and 6.4%. There was a significant difference in the SUVmax between the benign and malignant nodules (3.35 ± 1.69 vs. 6.64 ± 4.12; P max and the size of the cancer. Conclusion The results of this study suggest that incidentally found thyroid lesions by FDG-PET/CT, especially a focal FDG uptake and a high SUV, have a high risk of thyroid malignancy. Further diagnostic work-up is needed in these cases.

    As Th22 subsets are identified, their involvement in the pathogenesis of numerous autoimmune diseases has become apparent. In this study, we investigated differentiation of Th22 cells in the autoimmune thyroid diseases including Hashimoto's thyroiditis (HT) and Graves' disease (GD). Besides, we also explored the involvement of Th22 cells in an iodine-induced autoimmune thyroiditis (AIT) model (i.e., NOD.H-2(h4) mice). In HT patients, we showed the level of circulating Th22 cells correlated with the level of serum IL-22, and was significantly higher than in GD patients and healthy control subjects. Levels of serum IL-6, a major Th22 cell differentiation effector, were also higher in HT, and correlated with Th22 cells concentration. Peripheral blood mononuclear cells isolated from HT patients produced larger amounts of IL-6 in vitro than did those isolated from other groups. Furthermore, unlike those from GD patients, T lymphocytes from HT patients showed an enhanced differentiation in vitro into Th22 cells in the presence of recombinant IL-6 and TNF-α. In addition, levels of circulating Th22 cells and titers of thyroid peroxidase antibody were positively correlated in HT patients. In NOD.H-2(h4) mice, higher numbers of Th22 cells were observed in the spleens of the AIT group, while splenocytes of this group also produced larger amounts of IL-6 and IL-22 in vitro compared with the control. Intra-thyroid infiltrating IL-22+ lymphocytes were significantly increased in mice of the AIT group compared with the control. Our results indicate that Th22 cells may contribute to the pathogenesis of HT.

    Full Text Available Abstract Background It has recently become evident that circulating thyroid antibodies are found in excess among patients suffering from mood disorders. Moreover, a manic episode associated with Hashimoto's thyroiditis has recently been reported as the first case of bipolar disorder due to Hashimoto's encephalopathy. We report a case in which Hashimoto's thyroiditis was suspected to be involved in the deteriorating course of mood disorder and discuss potential pathogenic mechanisms linking thyroid autoimmunity with psychopathology. Case presentation A 43-year-old woman, with a history of recurrent depression since the age of 31, developed manic, psychotic, and soft neurological symptoms across the last three years in concomitance with her first diagnosis of Hashimoto's thyroiditis. The patient underwent a thorough medical and neurological workup. Circulating thyroperoxidase antibodies were highly elevated but thyroid function was adequately maintained with L-thyroxine substitution. EEG was normal and no other signs of current CNS inflammation were evidenced. However, brain magnetic resonance imaging evidenced several non-active lesions in the white matter from both hemispheres, suggestive of a non-specific past vasculitis. Brain single-photon emission computed tomography showed cortical perfusion asymmetry particularly between frontal lobes. Conclusion We hypothesize that abnormalities in cortical perfusion might represent a pathogenic link between thyroid autoimmunity and mood disorders, and that the rare cases of severe Hashimoto's encephalopathy presenting with mood disorder might be only the tip of an iceberg.

    2013-01-01

    Full Text Available Background. Papillary thyroid carcinoma (PTC, follicular thyroid adenoma (FTA, and thyroid nodular hyperplasia (TNH are the most frequent diseases of the thyroid gland. Previous studies described the involvement of dipeptidyl-peptidase IV (DPPIV/CD26 in the development of thyroid neoplasia and proposed it as an additional tool in the diagnosis/prognosis of these diseases. However, very little is known about the involvement of other peptidases in neoplastic and hyperplastic processes of this gland. Methods. The catalytic activity of 10 peptidases in a series of 30 PTC, 10 FTA, and 14 TNH was measured fluorimetrically in tumour and nontumour adjacent tissues. Results. The activity of DPPIV/CD26 was markedly higher in PTC than in FTA, TNH, and nontumour tissues. Aspartyl aminopeptidase (AspAP, alanyl aminopeptidase (AlaAP, prolyl endopeptidase, pyroglutamyl peptidase I, and aminopeptidase B activities were significantly increased in thyroid neoplasms when compared to nontumour tissues. AspAP and AlaAP activities were also significantly higher in PTC than in FTA and TNH. Conclusions. These data suggest the involvement of DPPIV/CD26 and some cytosolic peptidases in the neoplastic development of PTC and FTA. Further studies will help to define the possible clinical usefulness of AlaAP and AspAP in the diagnosis/prognosis of thyroid neoplasms.

    Background Hyalinizing trabecular tumor (HTT) is a rare thyroid neoplasm, which shares some histologic features with thyroid papillary carcinoma (TPC). Clinically, it is frequently misdiagnosed as papillary carcinoma, even for some experienced pathologists. The aim of this study was to investigate whether HTT is variant of TPC or HTT is an independent entity of thyroid neoplasm.Methods The expression of CK19, galectin-3, HBME-1 and MIB-1 was detected by immunohistochemical staining in 12 cases of hyalinizing trabecular tumor and 20 cases of thyroid papillary carcinoma.Results Two of the 12 HTT samples were positive or focally positive for CK19. Four of the 12 samples of HTT presented positive to galectin-3; 3 were stained strongly and the other one was focally positive. None of the 12 samples of HTT was positive for HBME-1. Five in 12 HTT samples were stained in nucleus for MIB-1. Almost all the 20 cases of thyroid papillary carcinoma were intensely stained for CK19, galectin-3 and HBME-1. Fifteen in 20 cases of thyroid papillary carcinoma showed nuclear staining for MIB-1.Conclusions HTT is an independent thyroid neoplasm, not a variant of TPC. This study could help in the differential diagnosis of HTT from TPC. CK19, galectin-3 and HBME-1 are adequate to identify HTT and TPC, but MIB-1 does not play an important role in discrimination between HTT and TPC.

    Patient: Male, 23 Final Diagnosis: Thyroid storm Symptoms: Delirium • diarrhea • fever • hypertension • hyperventilation • tachycardia • weight loss Medication: — Clinical Procedure: — Specialty: Endocrinology and Metabolic Objective: Unusual clinical course Background: The clinical presentation of thyroid storm includes fever, tachycardia, hypertension, and neurological abnormalities. It is a serious condition with a high mortality rate. Furthermore, some other complications affect the clinical course of thyroid storm. Although it is reported that prognosis is poor when thyroid storm is complicated by disseminated intravascular coagulation syndrome (DIC) and leukopenia, reports of such cases are rare. Case Report: A 23-year-old man presented with delirium, high pyrexia, diarrhea, and weight loss of 18 kg over 2 months. According to the criteria of Burch and Wartofsky, he was diagnosed with thyroid storm on the basis of his symptom-complex and laboratory data that confirmed the presence of hyperthyroidism. Investigations also found leukopenia, thrombocytopenia, and disseminated intravascular coagulation, all of which are very rare complications of thyroid storm. We successfully treated him with combined therapy including anti-thyroid medication, despite leukopenia. Conclusions: Early diagnosis and treatment are essential in ensuring a good outcome for patients with this rare combination of medical problems. PMID:25072662

    BACKGROUND: This study assessed the presence of oxidative damage and lipid peroxidation in thyroid neoplasia. METHODS: Using tissue microarrays and immunohistochemistry, we assessed levels of DNA damage (8-oxo-dG) and lipid peroxidation (4-HNE) in 71 follicular thyroid adenoma (FTA), 45 papillary thyroid carcinoma (PTC), and 17 follicular thyroid carcinoma (FTC) and matched normal thyroid tissue. RESULTS: Cytoplasmic 8-oxo-dG and 4-HNE expression was significantly higher in FTA, FTC, and PTC tissue compared to matched normal tissue (all p values < .001). Similarly, elevated nuclear levels of 8-oxo-dG were seen in all in FTA, FTC, and PTC tissue compared to matched normal (p values < .07, < .001, < .001, respectively). In contrast, a higher level of 4-HNE expression was detected in normal thyroid tissue compared with matched tumor tissue (p < .001 for all groups). Comparing all 3 groups, 4-HNE levels were higher than 8-oxo-dG levels (p < .001 for all groups) except that cytoplasmic levels of 8-oxo-dG were higher than 4-HNE in all (p < .001). These results were independent of proliferation status. CONCLUSION: High levels of DNA damage and lipid peroxidation in benign and malignant thyroid neoplasia indicates this damage is an early event that may influence disease progression.

    Background/Aims. Abnormalities in thyroid function tests (TFTs) are a common referral reason for pediatric endocrine evaluation. However, a sizable proportion of these laboratory abnormalities do not warrant therapy or endocrine follow-up. The objectives of this study were (a) to evaluate the prevalence of true thyroid dysfunction among pediatric endocrinology referrals for abnormal TFTs; (b) to identify the historical, clinical, and laboratory characteristics that predict decision to treat. Methods. This was a retrospective chart review of patients evaluated in pediatric endocrinology office during a weekly clinic designated for new referrals for abnormal TFTs in 2010. Results. A total of 230 patients were included in the study. Median age at referral was 12 years (range = 2-18); 56% were females. Routine screening was cited as the reason for performing TFTs by 33% patients. Majority was evaluated for hypothyroidism (n = 206). Elevated thyroid-stimulating hormone was the most common referral reason (n = 140). A total of 41 out of 206 patients were treated for hypothyroidism. Conclusions. Prevalence of hypothyroidism was 20%. Thyroid follow-up was not recommended for nearly one third of the patients. Among all the factors analyzed, an elevated thyroid-stimulating hormone level and antithyroglobulin antibodies strongly correlated with the decision to treat (P < .005).

  9. Report of a case of papillary thyroid carcinoma in association with Hashimoto's thyroiditis

    Full Text Available Hashimoto thyroiditis (HT is an autoimmune disease, known to be the most common cause of hypothyroidism in nonendemic goitrous areas. It is usually characterized by symmetric, painless, and diffused but sometimes localized swelling of the thyroid gland with features of hypothyroidism. Papillary thyroid carcinoma (PTC, on the other hand, is the most common yet less aggressive form of thyroid cancer, especially in iodine-deficient areas. The coexistence of the two diseases is possible but not common. This case study reports a 50-year-old female with a 10-year history of a huge goiter, which was essentially symptom-free until about 3 months prior to presentation when the patient started complaining of neck pain, dysphagia, productive cough, and cold intolerance. Physical examination revealed focal cystic and tender area in the multinodular swelling and associated cervical lymphadenopathy on the left side of the neck. The serum thyroid stimulating hormone was high, sub-normal T3, and the T4 was low. The fine needle aspiration cytology yielded 10 ml of aspirate of pus admixed with altered blood which on microscopy showed a few suspicious follicular epithelial cells with open nuclei admixed with mainly neutrophil polymorphs, siderophages, and foam cells in a hemorrhagic background. The patient had an incision biopsy that showed areas displaying PTC and HT.

    Full Text Available Abstract. Forty-two patients with progressive vulgar psoriasis (PASI = 19.7 ± 1.5 and 40 healthy volunteers were under investigation. Psoriatic patients were characterized by increased number of CD4+ CD95+ peripheral blood T lymphocytes, which correlates with clinical psoriatic score, and by increased levels of soluble Fas (sFas in serum, as compared to controls (resp., 1868.1 ± 186.8 pg/ml vs. 1281.4 ± 142.5 pg/ml, PLSD = 0.019. The levels of spontaneous lymphocyte apoptosis and anti-Fas (Mab-induced apoptosis in psoriatic patients did not differ from the controls. However, apoptosis induced by “oxidative stress” (50 M Н202, 4 hrs was depressed in the patients. Moreover, a simultaneous assessment of cell cycle structure (metachromatic staining with Acridine Orange, apoptosis and Fas receptor expression (AnnV-FITC/antiFas mAbs-PE staining following a short-term mitogenic stimulation (PHA-P, 5 µg/ml, 24 hrs were performed. We found no marked differences in mitogenic reactivity, activation-induced apoptosis, and activation-induced Fas receptor expression when studying lymphocytes from healthy donors and psoriatic patients. However, PHA-activated lymphocytes from psoriatic patients displayed a significantly decreased ratio of AnnV+CD95+ to the total AnnV+ subpopulation, thus suggesting a decreased role of Fas-dependent mechanisms of apoptosis during the cell activation. The data obtained confirm a view, that an abnormal lymphocyte “apoptotic reactivity”, which plays a crucial role in the mechanisms of autoimmunity, may also of importance in the pathogenesis of psoriasis.

    Background Several studies have evaluated the association between obesity and thyroid cancer risk. However, the results remain uncertain. In this study, we conducted a meta-analysis to assess the association between obesity and thyroid cancer risk. Material/Methods Published literature from PubMed, EMBASE, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM) were retrieved before 10 August 2014. We included all studies that reported adjusted risk ratios (RRs), hazard ratios (HRs) or odds ratios (ORs), and 95% confidence intervals (CIs) of thyroid cancer risk. Results Thirty-two studies (n=12 620 676) were included in this meta-analysis. Obesity was associated with a significantly increased risk of thyroid cancer (adjusted RR=1.33; 95% CI, 1.24–1.42; I2=25%). In the subgroup analysis by study type, increased risk of thyroid cancer was found in cohort studies and case-control studies. In subgroup analysis by sex, both obese men and women were at significantly greater risk of thyroid cancer than non-obese subjects. When stratified by ethnicity, significantly elevated risk was observed in Caucasians and in Asians. In the age subgroup analysis, both young and old populations showed increased thyroid cancer risk. Subgroup analysis on smoking status showed that increased thyroid cancer risks were found in smokers and in non-smokers. In the histology subgroup analyses, increased risks of papillary thyroid cancer, follicular thyroid cancer, and anaplastic thyroid cancer were observed. However, obesity was associated with decreased risk of medullary thyroid cancer. Conclusions Our results indicate that obesity is associated with an increased thyroid cancer risk, except medullary thyroid cancer. PMID:25612155

    Results: Microscopic changes in thyroid gland of albino rats were evident after 8 weeks of drug administration which include marked pleomorphism, shrinkage in size of thyroid follicles, excess of colloid and marked vacuolations in acini. At 12th week of study, follicles were found both macro and micro follicular, with variable lining epithelium and hyperchromatic nuclei. Lining epithelium of some follicles was disrupted. The stroma was infiltrated with lymphocytes and eosinophils and there were some interfollicular hemorrhages. Conclusions: Lithium given over prolonged period will cause macro and micro follicular goiter with hyperplastic epithelium and hyper chromatic nuclei, hyperplasia of stroma with increased vascularity, sometimes hemorrhages and finally may lead to thyroiditis like picture. So, it is advised that patients on lithium therapy should be periodically evaluated for thyroid dysfunction. [Int J Res Med Sci 2014; 2(1.000: 279-284

    Full Text Available Abstract Primary lymphoma is an uncommon malignancy of the thyroid, comprising of 0.6 to 5 per cent of thyroid cancers in most series. Primary thyroid lymphomas (PTL occur most commonly in elderly women and are commonly of B- cell origin. These frequently present in clinical stage IE and IIE. We report here ten cases of PTL diagnosed over a period of about 7 years in our institute. Out of these ten cases, nine were diagnosed on fine needle aspiration cytology (FNAC and one case was misdiagnosed as lymphocytic thyroiditis. This case was diagnosed as Non- Hodgkin's lymphoma on surgical specimen. Five patients are disease free and doing well, while two died of disease and the other two were lost to follow-up. One patient is currently on chemotherapy. The salient clinical, biochemical, radiological features, FNA findings along with diagnostic difficulties are discussed.

    Full Text Available Abstract Background Vitiligo is an acquired depigmenting disorder due to destruction of melanocytes. Although many theories have been suggested for its pathogenesis, the role of autoimmunity is the most popular one. The association of vitiligo with autoimmune thyroid diseases and the increased prevalence of autoantibodies including thyroid autoantibodies in vitiligo favor this role. Our objective was to compare the frequency of thyroid peroxidase antibody (anti-TPO in vitiligo patients with healthy subjects in Iran. Methods Ninety-four cases of vitiligo (46 female and 48 male and 96 control subjects (49 female and 47 male were enrolled in this controlled study. Patients with known thyroid disease, history of thyroid surgery and those receiving thyroid medications were not included. The two groups were matched regarding gender and age. The demographic data, symptoms related to thyroid diseases and results of skin and thyroid examinations were recorded in a questionnaire for each subject. Thyroid function tests including free T3, free T4 and TSH-IRMA were performed. Anti-TPO levels were assessed as well. The collected data were analyzed by SPSS version-11 in vitiligo patients and subgroups according to gender, age, extent, and duration of the disease compared with the control group. Results Anti-TPO was detected in 17 (18.1% of patients affected by vitiligo, while this figure was 7 (7.3% in the control group; the difference was significant with p-value The difference of the frequency of anti-TPO was not significant regarding the duration and extent of vitiligo. In addition, there was no significant difference in the levels of free T3, free T4, and TSH in vitiligo patients compared with the control group. Conclusion According to our study, anti-TPO was shown to be significantly more common in vitiligo patients especially in young women, compared with control group. As this antibody is a relatively sensitive and specific marker of autoimmune thyroid

    2014-07-01

    Full Text Available Autoimmune thyroid diseases (ATDs are immune-endocrine disorders affecting the thyroid gland and, eventually, also a number of other systemic targets, including the brain and the nervous system. Encephalopathy associated with autoimmune thyroid disease (EAATD is a rare, heterogeneous condition arising from the background of an ATD. It is characterised by neurological and/or psychiatric symptoms with acute or sub-acute onset, and virtually any neurological or psychiatric symptom can appear. However, EAATD often presents with confusion, altered consciousness, seizures, or myoclonus. The majority of cases are associated with Hashimoto’s thyroiditis, but a number of patients with Graves’ disease have also been described. EAATD is likely an immune-mediated disorder. Its exact prevalence has not been precisely elucidated, with an increasing number of cases reported in the last few years. Most EAATD patients respond in a dramatic manner to corticosteroids. However, the immunosuppressive treatment may require a long course (up to 12 months. The increasing number of EAATD cases reported in the literature demonstrates a growing interest of the scientific community about this condition, which still requires a better definition of its pathophysiology, the diagnostic criteria, and the most appropriate management, including the long-term follow-up of patients. The current clinical evidence about EAATD is mostly based on the report of single cases or small cohort studies. In this review, we present the current knowledge about EAATD, with a dedicated focus to the clinical management of the patients from a diagnostic and therapeutic perspective.

    AIM: To investigate the effect of interleukin-10 (IL-10) gene on experimental autoimmune thyroiditis mice.METHODS: Mice were immunized to induce autoimmune thyroiditis with porcine thyroglobulin (pTg), and thyroids of mice were injected with IL-10 DNA. On d 28 after immunization with pTg, mRNA expression of IL-10 inthyroid glands was detected and thyroid specimens were histopathological studied. RESULTS: The mRNA expression of IL-10 was detected in thyroid glands on d 7 and 14 after injection of IL-10 plasmid DNA or on COS-7 cells48 h after IL-10 plasmid DNA transfection. In addition, hlL-10 levels in culture media significantly increased 48 hand 72 h after IL-10 plasmid DNA transfection. Infiltration index of lymphocytes (1.1±0.4) in thyroids ofIL-10-treated mice was significantly lower than that of pcDNA3-null-treated mice (2.2±0.5) (P<0.01). Comparedwith pcDNA3-null control mice, IL-10-treated mice had lower levels of serum IFN-γ(P<0.01). CONCLUSION:The direct injection of DNA expression vectors encoding IL-10 into thyroid significantly inhibited development oflymphocytic infiltration of thyroid of autoimmune th,yroiditis mice, and alleviated the progression of this disease.

    The risk factors and mechanisms for the development of postpartum thyroid dysfunction have been widely discussed. However data on patients suffered spontaneous or induced abortion during early pregnancy are scarce. To reveal the characteristics of thyroid dysfunction in women after an abortion in the first trimester of pregnancy. A total of 28 women (18 euthyroid, 10 with thyroid dysfunction), mean age 30.46 ± 1.01 years following abortion in the first trimester have been included in the study. Thyroid-stimulating hormone (TSH), free triiodthyronine (FT3), free thyroxine (FT4), thyreoglobulin antibodies (TgAb), thyroid peroxidase antibodies (TPOAb) were measured and ultrasound assessment of the thyroid was performed 3 and 9 months after the interruption of pregnancy. Hypothyroidism was found in 6 of the women with thyroid dysfunction and thyrotoxicosis--in 4. Clinical features of thyroid dysfunction were observed in 3 patients while in the remaining 7 cases, diagnosis was made on the basis of hormonal levels. Positive titers of thyroid autoantibodies were detected in the majority of the cases with functional disordes. In 6 patients thyroid dysfunction was transient and in 4 hormonal abnormalities persisted on by the 9th month after the abortion. The comparative analysis showed that the volume of the thyroid gland and the degree of hypoehogenicity were significantly higher in patients with thyroid dysfunction compared to euthyroid women. Thyroid dysfunction after abortion in the first trimester is mainly of autoimmune pathogenesis and its characteristics do not differ from those of postpartum thyroiditis. In the majority of patients these disorders are subclinical and may remain unrecognized. A close active follow up of patients at increased risk of functional thyroid disorders after an abortion is required in order to prevent morbidity and identify the cases developing permanent thyroid dysfunction.

    Background Incidental focal fluorine-18-2-fluoro-2-deoxy-D-glucose (FDG) uptake in the thyroid is not uncommon. A significant proportion is due to intercurrent thyroid cancer on further evaluation. Purpose To investigate and discuss the clinical significance and management of incidental focal FDG uptake in the thyroid gland on positron emission tomography/computed tomography (PET/CT) in patients with non-thyroidal malignancy. Material and Methods We investigated 188/7896 (2.4%) patients who had incidental focal thyroid uptake on FDG PET/CT in an oncology population over a 45-month period. Diagnosis was confirmed in 63 patients of whom 59 patients had histopathological verification. Results Thirty-two percent of confirmed cases were malignant comprising intercurrent thyroid cancer in three-quarters of these patients. Maximum standardized uptake values of the thyroid lesions and SUV ratios compared with background thyroid and mediastinal uptake were not predictive of a benign or malignant etiology. In patients with incidental thyroid cancers, more than half had non-papillary and intermediate to high-risk pathology. Conclusion Focal FDG uptake in the thyroid gland on PET/CT showed a malignancy risk of 32%. The intensity of uptake does not predict histology and underpins the importance of further investigations to exclude intercurrent thyroid cancer in suitable patients

    2016-08-01

    Full Text Available BACKGROUND Goitre or swelling of thyroid gland is very common in North-East region and is encountered frequently in clinical practice. Goitre is a compensatory hypertrophy of thyroid gland and it has been recognised for centuries even back to the times of Ebers Papyrus (1500 BC (LE McDonald. The thyroid is the largest endocrine gland present in all mammals. In some disease conditions, an individual has to undergo a complete thyroidectomy and live on thyroid supplements for life. Is there a possibility of xenograft and xenotransplant? With this view a comparative study of the thyroid gland was under taken in the Dept. of Anatomy, Gauhati Medical College, Guwahati. The main purpose of the study was to see if thyroid gland of human was in any way similar to thyroid gland of other mammals. Xenograft and Xenotransplantation are the latest research studies going on these days. By these techniques, tissues and organs of one species can be transplanted or grafted into another species. MATERIALS AND METHODS The study of thyroid gland was conducted in Dept. of Anatomy, Gauhati Medical College. The various species included for studies were of human, pig and goat. They were divided into three groups I, II, and III. The specimen of human was collected from morgue of Gauhati Medical College. The specimen of pig and goat were collected from College of Veterinary Sciences, Gauhati. In all animals, the size, shape, length, breadth, thickness was recorded. RESULT The length, breadth, thickness of thyroid gland in group I, II and III were taken with the help of Vernier callipers. Weight was measured with the help of electronic weighing machine. The results were statistically analysed. DISCUSSION The findings of this study were compared with the findings of work done by other authors previously. CONCLUSION In this study, it was observed that biometrical values were different in all the mammals but morphological characters were almost similar

    • BACKGROUND: Because of different values of thyroid volume in different populations, and the effects of different trace element and geographic substances on thyroid volume, we decided to evaluate thyroid volume and its determinants using ultrasound in healthy adults of Isfahan, a centrally located city in Iran, an iodine replete area.
    • METHODS: In a cross-sectional study, 1500 healthy adults were enrolled by cluster sampling. Serum TSH level and morning urine iodine level were measured. Thyroid exam was performed according to WHO criteria and history of previous or present thyroid disease was taken. If all the mentioned results were normal they were considered clinically normal. One third of these normal subjects referred for thyroid ultrasonography. If ultrasonography of thyroid parenchyma texture was normal, and there was no nodule by sonography (thyroid incidentaloma, thyroid volume was measured using ellipsoid formula (X×Y×Z×8/6. Correlation between thyroid volume and age, sex, BMI, TSH level and urinary iodine concentration (UIC was determined by Pearson correlation coefficient, t-Test and Kolmogorov-Smirnov. Thyroid volume more than 97% of this population was considered as goiter sonographically. Data expressed as mean ± SD, unless otherwise stated.
    • RESULTS: We finally studied 200 subjects (123 Males, 77 females, average age: 37.27 ± 11.80 Years. The overall thyroid volume was 9.53 ± 3.68 ml. Males thyroid volume (10.73 ± 3.44 ml was significantly higher than the females one (7.71 ± 2.63 ml (P < 0.001. The thyroid volume ranges were 3-23.9 ml, 3.6-23.9 ml and 3-14.3 ml in all, males and females, respectively. Thyroid volume values more than 97 percentile of this reference range were 10.14 ml, 11.48 ml and 8.37 ml in all, males and females respectively, and were considered goiter sonographically.

      Several changes in thyroid hormone secretion, metabolism, and action occur with the increase in age. Aging is often associated with a decrease in serum thyroid stimulating hormone and T3 levels, whereas serum free T4 levels usually remain unchanged. The prevalence of thyroid dysfunction is higher in the elderly as compared to the younger population. In elderly individuals the non-specific clinical manifestations of thyroid hormone excess or deprivation can cause confusion in the clinical setup; while some of the symptoms of thyroid disease are similar to those in younger patients, it is not uncommon for both hyperthyroidism and hypothyroidism to be manifested in subtle ways in older patients, often mimicking symptoms of aging or masquerading as diseases of the cardiovascular, gastrointestinal, or nervous system. In addition, diagnosis of thyroid disorders is commonly complicated, due to chronic, non-thyroidal illness or medication therapy. Early diagnosis and treatment of overt thyroid disorders is crucial, since these disorders are associated with increased morbidity and mortality in the elderly, usually due to common coexistent diseases such as diminished cardiovascular reserve. Treatment of subclinical thyroid disease should also be considered, based on a combination of age, symptoms and risk factors in the individual patients. In addition, both prevalence and aggressiveness of thyroid cancer increase with age. This review summarizes the changes of thyroid function, as well as the clinical manifestations and treatment of thyroid disorders with advancing age. Copyright © 2011 Elsevier Ireland Ltd.

      Thyroid disease is common in younger women and may be a factor in reproductive dysfunction. This probably only applies to severe cases of hyper- or hypothyroidism. Once adequately treated, neither of these disorders significantly impacts on fertility. The key is to recognize and to treat thyroid disorders in the reproductive-age woman before conception. Thyroxine therapy and even antithyroid drug therapy should be continued during pregnancy as necessary. Pregnancy is a euthyroid state that is normally maintained by complex changes in thyroid physiology. The fetal and neonatal hypothalamic-pituitary-thyroid system develops independently, but it may be influenced by thyroid disease in the mother. Early pregnancy is characterized by an increase in maternal T4 secretion stimulated by hCG and an increase in TBG, resulting in the elevated total serum T4 in pregnancy. The debate continues as to whether maternal T4 is important in early or late fetal brain development. If so, the physiologic changes in thyroid hormone secretion and transport in early pregnancy would help to ensure that a sufficient amount of thyroid hormone was available. There is new evidence in human subjects that substantial maternal T4 can cross the placenta during pregnancy, and this may be particularly important when fetal thyroid function is compromised as a result of congenital hypothyroidism. Maternal and fetal/neonatal outcomes in pregnancy are adversely affected if severe hypothyroidism is undiagnosed or inadequately treated. Thyroid function tests should be obtained during gestation in women taking T4 and appropriate dose adjustments should be made for TSH levels outside a normal range. The TSH-receptor blocking antibodies from the mother are a recognized cause of congenital hypothyroidism in the fetus and neonate that can be permanent or transient. If neonatal hypothyroidism is detected through neonatal screening programs, and prompt and adequate T4 replacement therapy is instituted as soon as

      Recent clinical practice guidelines on thyroid dysfunction and pregnancy have changed health care provided to pregnant women, although their recommendations are under constant revision. Trimester- and area-specific reference ranges for serum thyroid-stimulating hormone are required for proper diagnosis of hypothyroidism and hyperthyroidism. There is no doubt on the need of therapy for overt hypothyroidism, while therapy for subclinical hypothyroidism is controversial. Further research is needed to settle adverse effects of isolated hypothyroxinemia and thyroid autoimmunity. Differentiation between hyperthyroidism due to Graves' disease and the usually self-limited gestational transient thyrotoxicosis is critical. It is also important to recognize risk factors for postpartum thyroiditis. Supplementation with iodine is recommended to maintain adequate iodine nutrition during pregnancy and avoid serious consequences in offspring. Controversy remains about universal screening for thyroid disease during pregnancy or case-finding in high-risk women. Opinions of some scientific societies and recent cost-benefit studies favour universal screening.

      We report an extremely rare case of papillary thyroid microcarcinoma (PTMC) in the thyroid pyramidal lobe (TPL). A 48-year-old woman underwent ultrasound-guided fine-needle aspiration for a small thyroid nodule in the right lobe in local clinic, and it revealed a malignant cytology. On preoperative ultrasonography for tumor staging in our hospital, another small suspiciously malignant hypoechoic nodule was detected in the left TPL. Total thyroidectomy and central nodal dissection were performed. Histopathology confirmed PTMCs in the left TPL and both thyroid lobes. Ultrasonography for TPL should be required for complete evaluation of possible multifocality of thyroid malignancy.

      The purpose of modelling the negative-feedback control mechanism of the hypothalamus-pituitary-thyroid (HPT) axis in autoimmune (Hashimoto's) thyroiditis is to describe the clinical course of euthyroidism, subclinical hypothyroidism and overt hypothyroidism for patients. Thyroid hormone thyroxine (T4) and triiodothyronine (T3) levels are controlled by negative-feedback control through thyroid-stimulating hormone (TSH). T4, like other hormones, can be bound or unbound; the unbound T4 (FT4) is used as a marker for hypothyroidism. Autoimmune thyroiditis is a disease in which the thyroid-infiltrating lymphocytes attack autoantigens in follicle cells, destroying them over a long time. To describe the operation of the feedback control, we developed a mathematical model involving four clinical variables: TSH, FT4, anti-thyroid peroxidase antibodies and the thyroid gland's functional size. The first three variables are regularly measured while the last variable is determined through relationships between the other three variables. The problem of two different time scales for circulating hormones and thyroid damage is addressed using singular perturbation theory. Analysis of the mathematical model establishes stability and conditions under which the diseased state can maintain the slow movement toward diseased state equilibrium. Although we have used four variables in modelling the feedback control through the HPT axis, the predicted clinical course given any set of parameters is shown to depend on the steady-state levels of TSH and FT4. This observation makes possible the development of the clinical charts based only on the levels of TSH, time and potential steady-state values. To validate the model predictions, a dataset obtained from a Sicilian adult population has been employed. © The Authors 2013.

    Full Text Available BACKGROUND Thyroid carcinoma accounts for less than 1% of cancer cases. In the Indian subcontinent, thyroid carcinoma exhibits a varied disease profile and geographic differences in the pattern of cancer, the knowledge of which impacts a more favourable clinical outcome. The present study aims to profile Thyroid carcinoma in areas of age, gender, geographic domicile, morphology & clinical features and referral paradigm of cases in King George Hospital, Visakhapatnam, the tertiary referral hospital for coastal Andhra Pradesh. METHODS & MATERIALS The Retrospective Study 1988-2004 includes 188 patients who attended Department of Nuclear Medicine for pre & postoperative nuclear scan, thyroid carcinoma treatment protocol, whose clinical features, relevant laboratory data, histopathological reports & prognosis were analysed. RESULTS Papillary thyroid carcinoma was present in 79% and Follicular thyroid carcinoma in 19%, Anaplastic & Medullary Thyroid Carcinoma in 2% of cases (n=188, male to female ratio 1:0.62. Coastal city of Visakhapatnam recorded highest 59% of cases who were in their 3rd and 4th decades. West Godavari District had lowest at 5%. Clinical presentation of cases of Thyroid carcinoma as a Nodule (61% which was the most common form lead to maximum number of referrals (n=82 from the Department of Surgery, King George Hospital. CONCLUSION In coastal Andhra Pradesh, papillary thyroid carcinoma was the most dominant form. Women were more affected than men. Painless thyroid nodule was the most common clinical feature. Coastal city of Visakhapatnam recorded highest number of cases and maximum referrals were from Department of Surgery.

    Full Text Available Abstract Background The Ras association domain family (RASSF encodes for distinct tumor suppressors and several members are frequently silenced in human cancer. In our study, we analyzed the role of RASSF2, RASSF3, RASSF4, RASSF5A, RASSF5C and RASSF6 and the effectors MST1, MST2 and WW45 in thyroid carcinogenesis. Results Frequent methylation of the RASSF2 and RASSF5A CpG island promoters in thyroid tumors was observed. RASSF2 was methylated in 88% of thyroid cancer cell lines and in 63% of primary thyroid carcinomas. RASSF2 methylation was significantly increased in primary thyroid carcinoma compared to normal thyroid, goiter and follicular adenoma (0%, 17% and 0%, respectively; p RASSF2 in their primary thyroid tumors compared to those younger than 40 years (90% vs. 38%; p RASSF2 promoter hypermethylation correlated with its reduced expression and treatment with a DNA methylation inhibitor reactivated RASSF2 transcription. Over-expression of RASSF2 reduced colony formation of thyroid cancer cells. Functionally our data show that RASSF2 interacts with the proapoptotic kinases MST1 and MST2 and induces apoptosis in thyroid cancer cell lines. Deletion of the MST interaction domain of RASSF2 reduced apoptosis significantly (p Conclusion These results suggest that RASSF2 encodes a novel epigenetically inactivated candidate tumor suppressor gene in thyroid carcinogenesis.

    Full Text Available Here we report a case of a 45-year-old female who underwent thyroidectomy for thyroid cancer and presented 20 years later with a left renal mass. CT-guided core biopsy was performed, and imprints and histologic sections of the biopsy showed cells resembling thyroid follicular cells with a background containing colloid. Immunohistochemistry revealed positivity for thyroglobulin and thyroid transcription factor 1, consistent with metastatic follicular thyroid carcinoma (FTC. The patient later underwent radical nephrectomy; histologic sections of the resected tumor revealed an encapsulated lesion morphologically similar to the biopsy specimen. Thyroid metastases to the kidney are extremely rare and are often detected during postthyroidectomy surveillance by elevation in thyroid hormone levels, 131I scintigraphy, or 18F-fluorodeoxyglucose uptake in positron emission tomography studies. Treatment involves total thyroidectomy, resection of the metastatic foci, and 131I therapy. The differential diagnoses of renal metastasis of FTC include the encapsulated follicular variant of papillary thyroid carcinoma (PTC, which possesses some of the nuclear features seen in conventional PTC but may occasionally be indistinguishable from FTC in cytologic preparations, and renal lesions such as benign thyroidization of the kidney and thyroid-like follicular carcinoma of the kidney, which mimic FTC in histologic appearance but do not stain with thyroid markers.

    Full Text Available Abstract Background Lithium-induced thyroid abnormalities have been documented in many studies. They may occur despite normal plasma lithium levels. The objectives of this study were: 1 to determine possible relationship between lithium ratio, defined as erythrocyte lithium concentrations divided by plasma lithium concentrations, and thyroid abnormalities in bipolar patients receiving lithium and 2 to find other possible risk factors for developing thyroid abnormalities in the subjects. Methods Sixty-eight bipolar patients receiving lithium therapy were enrolled in a cross-sectional evaluation of thyroid function test and thyroid size. Patients were divided into two groups based on their thyroid function tests and thyroid sizes. Erythrocyte and plasma lithium concentrations were determined by atomic absorption spectrometry for each patient. Lithium ratio was then calculated. Results No significant differences were found between age, positive family history of affective disorder, plasma lithium concentration, erythrocyte lithium concentration, and lithium ratio comparing the two groups. Thyroid abnormalities was significantly higher in women than in men (p Conclusions Lithium ratio does not appear to have a predictive role for thyroidal side effects of lithium therapy. Female gender was the main risk factor. We suggest more frequent thyroid evaluation of bipolar women who are treated with lithium.

    Full Text Available Background: Primary hyperaparathyroidism (pHPT is often accompanied by underlying thyroid pathology that can confound preoperative parathyroid localization studies and complicate intra-operative decision making. The aim of this study was to examine the utility of preoperative thyroid ultrasonography (US in patients prior to undergoing parathyroidectomy for pHPT.Methods: An Institutional Review Board approved prospective study was undertaken from January 2005 through July 2008. All patients with pHPT meeting inclusion criteria (n=94 underwent preoperative thyroid ultrasound in addition to standard 99mTc-sestamibi scintigraphy for parathyroid localization. Demographics, operative management and final pathology were examined in all cases.Results: Fifty-four of the 94 patients (57% were noted to have a thyroid nodule on preoperative US, of which 30 (56% underwent further examination with fine needle aspiration biopsy. Alteration of the operative plan attributable to underlying thyroid pathology occurred in 16 patients (17%, with patients undergoing either total thyroidectomy (n=9 or thyroid lobectomy (n=7. Thyroid cancer was noted in 33% of patients undergoing thyroid resection, and 6% of all patients with HPT.Conclusions: The routine utilization of preoperative thyroid ultrasound in patients prior to undergoing parathyroid surgery for pHPT is indicated. The added information from this non-invasive modality facilitates timely management of co-incidental, and sometimes malignant, thyroid pathology.

    Full Text Available Abstract Background evaluation of thyroid function in neonates born from mothers affected by autoimmune thyroiditis in order to define if a precise follow-up is necessary for these children. The influence of maternal thyroid peroxidase antibody (TPOAb and L-thyroxine therapy during pregnancy on neonatal thyroid function was also investigated. Methods 129 neonates were tested for thyroid function by measurement of free thyroxine (FT4 and thyroid stimulating hormone (TSH in 3th day, 15th day and at one month of life. TPOAb were measured in all patients; periodical control of thyroid function were performed until 6 months of life if Ab were positive. Data concerning etiology of maternal hypothyroidism and maternal replacement therapy with L-thyroxine during pregnancy were retrospectively collected. Results 28% neonates showed at least a mild increase of TSH value at the different determinations. In the majority of them, a spontaneous completely normalisation of TSH value was observed within the first month life. L-thyroxine replacement therapy was started in 3 neonates. TPOAb titer and maternal L-thyroxine replacement therapy were not related to alteration of thyroid hormone function in our study population. Conclusions transient mild elevation of serum TSH above the normal reference value for age is frequently observed in the first month of life in infants born from mothers affected by autoimmune thyroiditis. Persistent hyperthyrotropinemia requiring replacement therapy is observed in 2.2% of these neonates. According to our experience, follow-up is recommended in these newborns; the most accurate and not invasive way to carefully monitor these infants after neonatal screening for CH seems to be serum-testing TSH between 2ndand 4th week of life.

    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).

    Full Text Available Background: Considering the controversial information regarding the effects of perchlorate on thyroid function of high risk population as neonates, and given the high prevalence rate of thyroid disorders specially congenital hypothyroidism in our region, this study aims to investigate for the first time in Iran, the relationship between drinking groundwater perchlorate and cord blood thyroid hormones level in an industrial region. Methods: In this cross-sectional study, drinking groundwater perchlorate level of rural areas of Zarinshahr, Isfahan was measured. Simultaneously, cord blood level of thyroid hormones of neonates born in the studied region was measured. Thyroid function test of neonates in regions with low and high perchlorate level were compared. Results: In this study, 25 tap water samples were obtained for perchlorate measurement. Level of cord blood thyroid stimulating hormone (TSH, T4 and T3 of 25 neonates were measured. Mean (standard deviation of perchlorate, TSH, T4 and T3 was 3.59 (5.10 μg/l, 7.81 (4.14 mIU/m, 6.06 (0.85 mg/dl, and 63.46 (17.53 mg/dl, respectively. Mean levels of thyroid function tests were not different in low ( 0.05. Conclusions: Perchlorate did not appear to be related to thyroid function of neonates in the studied industrial region. It seems that iodine status of the regions, as well as other environmental contaminants and genetic background, could impact on its relation with thyroid function of neonates.

    Differentiated thyroid carcinoma (DTC) is the most common endocrine malignancy. Surgical removal with radioactive iodine therapy is recommended for recurrent thyroid carcinoma, and the postsurgical thyroid removal is critical. This study evaluated the clinical values of radiofrequency ablation (RFA) in the postsurgical thyroid removal for DTC. 35 DTC patients who had been treated by subtotal thyroidectomy received RFA for postsurgical thyroid removal. Before and two weeks after RFA, the thyroid was examined by ultrasonography and (99m)TcO4 (-) thyroid imaging, and the serum levels of free triiodothyronine (FT3), free thyroxin (FT4), thyroid stimulating hormone (TSH) and thyroglobulin (Tg) were detected. The efficacy and complications of RFA were evaluated. Results showed that, the postsurgical thyroid removal by RFA was successfully performed in 35 patients, with no significant complication. After RFA, the average largest diameter and volume were significantly decreased in 35 patients (P > 0.05), and no obvious contrast media was observed in ablation area in the majority of patients. After RFA, the serum FT3, FT4 and Tg levels were markedly decreased (P RFA, radioiodine concentration in the ablation area was significantly reduced in the majority of patients. The reduction rate of thyroid update was 0.69±0.20%. DTC staging and interval between surgery and RFA had negative correlation (Pearson coefficient = -0.543; P = 0.001), with no obvious correlation among others influential factors. RFA is an effective and safe method for postsurgical thyroid removal of DTC.

    2014-01-01

    Full Text Available Background. A recent study has reported that high circulating 25-hydroxyvitamin D [25(OHD] is associated with low circulating thyroid-stimulating hormone (TSH levels, but only in younger individuals. The goal of the present study was to explore the relationship between vitamin D status and circulating TSH levels with thyroid autoimmunity and thyroid hormone levels taken into consideration in a population-based health survey of middle-aged and elderly individuals. Methods. A total of 1,424 Chinese adults, aged 41–78 years, were enrolled in this cross-sectional study. Serum levels of 25(OHD, TSH, thyroid hormones, and thyroid autoantibodies were measured. Results. The prevalence of vitamin D insufficiency was 94.29% in males and 97.22% in females, and the prevalence of vitamin D deficiency was 55.61% in males and 69.64% in females. Vitamin D status was not associated with positive thyroid autoantibodies after controlling for age, gender, body mass index, and smoking status. Higher 25(OHD levels were associated with lower TSH levels after controlling for age, FT4 and FT3 levels, thyroid volume, the presence of thyroid nodule(s, and smoking status in males. Conclusion. High vitamin D status in middle-aged and elderly males was associated with low circulating TSH levels independent of thyroid hormone levels.

    2013-01-01

    Full Text Available Introduction. Hashimoto's thyroiditis is a common form of chronic autoimmune thyroid disease (AITD and often coexists with other autoimmune diseases, but Hashimoto’s thyroiditis associated with an autosomal dominant neurofibromatosis type 1 is exceedingly rare. Case Presentation. A 30-year-old Bengali woman presented to the OPD with complaints of aching pain and tingling sensation in her hands and feet. Physical examination revealed dysmorphic facies, nodular swelling in the neck, cafe-au-lait spots, and neurofibromas covering the entire surface of her body. Her thyroid hormones were within normal limits. Thyroid ultrasound revealed a cystic area in the left lobe of the gland, and ultrasound-guided fine needle aspiration cytology revealed lymphocytic infiltration of the gland, suggesting Hashimoto’s thyroiditis. High levels of autoimmune antibodies such as antithyroglobulin and antimicrosomal antibodies confirmed the diagnosis. Conclusion. When encountered with a patient of Neurofibromatosis type 1, a physician should be careful about the possibility of a concomitant autoimmune disease. Clinical presentation of neurofibromatosis and Noonan syndrome often overlaps and recent studies have implicated a mutation in NF1 gene in the etiology of NFNS. More extensive reports and further investigations of such patients having combination of neurofibromatosis type 1 and autoimmune thyroiditis will certainly provide better understanding of this link in the near future.

    Full Text Available Thyroidal pain is usually due to subacute thyroiditis (SAT. In more severe forms prednisone doses up to 40 mg daily for 2-3 weeks are recommended. Recurrences occur rarely and restoration of steroid treatment cures the disease. Rarely, patients with Hashimoto’s thyroiditis (HT have thyroidal pain (painful HT, PHT. Differently from SAT, occasional PHT patients showed no benefit from medical treatment so that thyroidectomy was necessary. We report three patients who did not show clinical response to prolonged high dose prednisone treatment: a 50-year-old man, a 35-year-old woman, and a 33-year-old woman. Thyroidectomy was necessary, respectively, after nine-month treatment with 50 mg daily, two-month treatment with 75 mg daily, and one-month treatment with 50 mg daily. The two women were typical cases of PHT. Conversely, in the first patient, thyroid histology showed features of granulomatous thyroiditis, typical of SAT, without fibrosis or lymphocytic infiltration, typical of HT/PHT, coupled to undetectable serum anti-thyroid antibodies. Our data (1 suggest that not only PHT but also SAT may show resistance to steroid treatment and (2 confirm a previous observation in a single PHT patient that increasing prednisone doses above conventional maximal dosages may not be useful in these patients.

    Objective This study investigated clinical and pathological characteristics and risk factors in papillary thyroid carcinoma (PTC) patients’ native to Yunnan plateau in southwestern China. Methods Clinical data from 1,198 patients diagnosed with PTC (n=578) and control subjects (n=620) with benign thyroid disease (ie, thyroid nodule disease, benign thyroid diseases [BTD]) in Yunnan province were analyzed retrospectively. Results The mean patient age was lower for PTC than for BTD. Positive ratios of thyroid peroxidase antibody, thyroglobulin antibody (TGAb), and thyrotrophin receptor antibody (TRAb) were higher in PTC than in BTD patients. The ratio of PTC coexisting with Hashimoto’s thyroiditis (HT) or with lymphocytic thyroiditis was higher than that of BTD. The number of patients whose age at menarche was ≤13 years, who had given birth to less than or equal to two children, or who were in premenopause were higher in the PTC than in the BTD group. Multivariate conditional logistic regression analyses revealed that age >45 years, nodal size >1 cm, and elevated TG levels were protective factors against PTC. Abnormally elevated TGAb and TRAb levels were independent risk factors for PTC in females. Conclusion HT was not an independent risk factor for but was associated with PTC. TRAb is a risk factor for PTC in individuals living in the Yunnan plateau, but not for those in the plains region. PMID:27418831

    To investigate the expression of apoptosis-related protein (Fas, FasL, and Bcl-2) in the pathogenesis of autoimmune thyroid disorders (ATDs), immunohistochemical staining was performed on 20 Hashimoto's thyroiditis (HT), 20 Graves' disease (GD), and 20 thyroid follicular adenoma (TFA, as control). All the cases expressed Fas, mainly on the cell surface and cytoplasm. FasL was found in 17 cases of the TFA. Bcl-2 was detected in 15 cases of HT, 19 of GD and 17 of TFA. In TFA, a moderate Fas expression and a minimal or no FasL expression was detected on follicular cells. In HT, the follicles adjacent to infiltrating lymphocytes showed increased levels of Fas and FasL expression. A weaker staining of Fas and FasL was exhibited on infiltrating lymphocytes than on thyrocytes. In a comparison of GD with HT, thyrocytes and lymphocytes showed similar Fas staining, but for FasL the staining was rather weaker in HT. The expression of Bcl-2 was nearly identical in GD and TFA, but much weaker on the follicular cells in vicinity of lymphocytes and on the lymphocytes located in germinal centers of HT tissues. The expression of Fas, FasL, Bcl-2 in Hashimoto's thyroiditis and Graves' disease were almost same. FasL strong expression and Bcl-2 weak expression on the follicles in HT may induce apoptosis. These results provided evidence for expression of Fas, FasL and Bcl-2 in the pathogenesis of autoimmune thyroid disease. The lymphocytes seem not to be directly engaged in the process via their own FasL, but they may provide some cytokines that, in turn, upregulate Fas and/or FasL expression to induce apoptosis.

    Constitutive Fas ligand (FasL) expression by specialized cells in the body participates in the immune privilege status of tissues containing these cells. This property has been used to prevent rejection of allogeneic grafts. Nevertheless, the mechanism responsible for such protection has not been fully elucidated. Unfortunately, grafting of FasL transgenic (TG) tissues has been unsuccessful. We have generated TG mice expressing FasL (soluble + membrane bound) on thyroid follicular cells (TFC), and used them to show that ectopic FasL expression prevents thyroid allograft rejection. FasL expression on TFC led to markedly decreased anti-allogeneic, cytotoxic, and helper T lymphocyte activities. The alloantibody response in TG thyroid recipients was either completely inhibited or switched toward a T2-Ab response. Surprisingly, the beneficial effect of FasL on TG thyroid grafts was abolished by host CD4(+) T cell depletion. Host CD8(+) T cell depletion improved nontransgenic (NTG), but not TG graft survival. Altogether, our results suggest that FasL-induced tolerance is concomitant with a move away from a T1 type response, and a CD4 T cell-mediated regulation of the allocytotoxic T cell response. These results were dependent upon the level of FasL expression on TFC, in that low expression of FasL led to a less marked effect compared with the effect observed with high expression of FasL. These results provide some insight into the role of FasL in regulating destructive alloimmune responses in the case of whole organ grafting, and they have important implications for the development of FasL-based immunotherapy in organ transplantation.
