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

    , and they may even interact mutually and counteract each other. Numerous studies have evaluated the effect of (131)I therapy, but results have been conflicting due to differences in design, sample size, patient selection, and dose calculation. It seems clear that no single factor reliably predicts the outcome...... of an exact thyroid dose is error-prone due to imprecise measurement of the (131)I biokinetics, and the importance of internal dosimetric factors, such as the thyroid follicle size, is probably underestimated. Besides these obstacles, several potential confounders interfere with the efficacy of (131)I therapy...

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

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

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

    Benign thyroid disorders are among the most common diseases in Germany, affecting around 15 million people and leading to more than 100,000 thyroid surgeries per year. Since the first German guidelines for the surgical treatment of benign goiter were published in 1998, abundant new information has become available, significantly shifting surgical strategy towards more radical interventions. Additionally, minimally invasive techniques have been developed and gained wide usage. These circumstances demanded a revision of the guidelines. Based on a review of relevant recent guidelines from other groups and additional literature, unpublished data, and clinical experience, the German Association of Endocrine Surgeons formulated new recommendations on the surgical treatment of benign thyroid diseases. These guidelines were developed through a formal expert consensus process and in collaboration with the German societies of Nuclear Medicine, Endocrinology, Pathology, and Phoniatrics & Pedaudiology as well as two patient organizations. Consensus was achieved through several moderated conferences of surgical experts and representatives of the collaborating medical societies and patient organizations. The revised guidelines for the surgical treatment of benign thyroid diseases include recommendations regarding the preoperative assessment necessary to determine when surgery is indicated. Recommendations regarding the extent of resection, surgical techniques, and perioperative management are also given in order to optimize patient outcomes. Evidence-based recommendations for the surgical treatment of benign thyroid diseases have been created to aid the surgeon and to support optimal patient care, based on current knowledge. These recommendations comply with the Association of the Scientific Medical Societies in Germany requirements for S2k guidelines.

  7. Side effects and risks of radioiodine treatment of benign thyroid diseases

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

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

    Dose planning prior to radioiodine therapy of benign thyroidal disease is usually based on macrodosimetry. The paper shows that this assumption is acceptable. The common concepts for dose planning are given. The following target doses are nowadays widely accepted: 150 Gy for euthyroid goiter, 400 Gy for toxic adenoma, 150 Gy for disserminated autonomy, 200 Gy for hyperthyroid Grave's disease if posttherapeutic euthyroidism is intended, and 250 (to 300) Gy if the risk of recurrency is to be minimized ('ablative' concept). Finally, a surveyfis given concerning the precision in which the parameters relevant for the dose calcultion can be determined. For realistic favourable conditions, the dose can be determined with an accuracy of better than ±25%. (orig.) [de

  12. Evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases

    The intention of the present thesis was the evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases. It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ( 131 I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with 131 I with its nadir on day 3 of therapy (decline by 15.71 ng/l or 27

    The aim of this study was to investigate the influence of a combined supplementation with magnesium, selenium and coenzyme Q10 on the morphology of the thyroid in patients with benign diseases. The clinical examination and treatment approach aims additionally at treating musculoskeletal and psychological stress. A group of 8 patients (5 with hyperthyroidism, 3 with hypothyroidism) who initially attended a public institution received additional treatment at our private institution. The basic pharmacological treatment, i.e. substitution or thyreostatic, was kept unchanged. The inclusion of patients required good quality ultrasound images to be available. Initially the changes of the musculoskeletal system were corrected. Following this, stress components were also treated. After a period of 2-4 years of supplementation we observed a normalization of thyroid morphology as evidenced on ultrasound while at the same time there was a reduction of perfusion intensity. Thyroid antibody titers decreased in the majority of cases. Failure of the treatment was seen in 2 cases of chronic thyroiditis that was present for more than 10 years. The ultrasound images of these patients suggest a possible fibrosis. In spite of the limitation due to the small number of cases, our observational study has delivered proof of concept for our examination and treatment model for benign thyroid disease. Our results challenge validity of the prevailing dogma of a destructive unstoppable "autoimmune" destructive process of the gland. At the same time it shows new therapeutic options for patients with thyroid disease.

    External fractionated radiotherapy of cancer increases the risk of cardio- and cerebrovascular events, but less attention has been paid to the potential side effects on the arteries following internal radiotherapy with radioactive iodine (RAI), i.e. 131-iodine. About 279 per million citizens in the western countries are treated each year with RAI for benign thyroid disorders (about 140,000 a year in the EU), stressing that it is of clinical importance to be aware of even rare radiation-induced side effects. In order to induce or accelerate atherosclerosis, the dose to the carotid arteries has to exceed 2 Gy which is the known lower limit of ionizing radiation to affect the endothelial cells and thereby to induce atherosclerosis. To estimate the radiation dose to the carotid arteries following RAI therapy of benign thyroid disorders. Assuming that the lobes of the thyroid gland are ellipsoid, that the carotid artery runs through a part of the lobes, that there is a homogeneous distribution of RAI in the lobes, and that the 24 h RAI uptake in the thyroid is 35% of the 131 I orally administrated, we used integrated modules for bioassay analysis and Monte Carlo simulations to calculate the dose in Gy/GBq of administrated RAI. The average radiation dose along the arteries is 4-55 Gy/GBq of the 131 I orally administrated with a maximum dose of approximately 25-85 Gy/GBq. The maximum absorbed dose rate to the artery is 4.2 Gy/day per GBq 131 I orally administrated. The calculated radiation dose to the carotid arteries after RAI therapy of benign thyroid disorder clearly exceeds the 2 Gy known to affect the endothelial cells and properly induce atherosclerosis. This simulation indicates a relation between the deposited dose in the arteries following RAI treatment and an increased risk of atherosclerosis and subsequent cerebrovascular events such as stroke.

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

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

    The main benefits of robot-assisted transaxillary thyroid surgery are to overcome the technical limitations of other endoscopic procedures for this surgical pathology and to avoid any cervical skin incision. This article describes the first experience of a Romanian team with the endoscopic robot-assisted thyroid surgery. We used the da Vinci SI intuitive surgical system to carry out 50 thyroid operations: 33 unilateral total lobectomies with isthmectomy (TL), 8 unilateral total lobectomies, with contralateral subtotal lobectomy, and 9 total thyroidectomies. Preoperatively, the patients were diagnosed with nodular goiter in 42 cases, nodular autoimmune thyroiditis in 3 cases, Basedow disease in 2 cases, toxic thyroid adenoma in 2 cases, and diffuse goiter in 1 case. We analyzed the clinical characteristics, size and location of the nodules, surgery duration, postoperative complications, pain medication, histopathological findings and postoperative cosmetic results. All surgical procedures were carried out without major incidents. One case required conversion to open approach. The mean length of surgery was 159 ± 38.2 min and the average console time was 68 ± 39.9 min; postoperatively, we recorded one case of transient brachial plexus neurapraxia, one transient vocal cord paresis, one transient hypocalcemia, and four postoperative wound complications. The final histopathological examination revealed two cases of well-differentiated carcinoma. This paper reports the largest series to date in Southeast Europe about robot-assisted transaxillary thyroidectomy. On a group of selected Caucasian patients, postoperative results were similar to open cervicotomy in terms of postoperative complications. The major cosmetic advantage is the absence of scar in the anterior cervical region.

[German] Ziel dieser Studie ist es, neue und bislang zum Teil kontrovers diskutierte Indikationen zur Bestimmung des Thyreoglobulins (Tg) bei unterschiedlichen Schilddruesenerkrankungen in der klinischen Routine zu ueberpruefen. Methoden: Die Studie umfasst folgende Kollektive: 250 gesunde Probanden, 50 Patienten mit euthyreoter Struma diffusa, 161 Patienten mit euthyreoter Knotenstruma (davon 108 operierte Faelle, wobei sich 17 Karzinome fanden), 60 hyperthyreote Patienten mit autonomer Knotenstruma, 150 Patienten mit Thyreoiditis Hashimoto und 30 hyperthyreote Patienten mit M. Basedow. Ergebnisse: Die Grenze des Referenzbereichs errechnete sich zu 30 ng Tg/ml. Die Analyse der diffusen Strumen zeigte eine lineare Abhaengigkeit des Tg-Spiegels von der Schilddruesengroesse, wobei der Erwartungswert in etwa dem Organvolumen in ml entsprach. Knotige Veraenderungen fuehrten zu einem ueberproportionalen Tg-Anstieg, der allerdings einer grossen Varianz unterlag und daher im Einzelfall nur schwer abzuschaetzen war. Von den 17 Patienten mit Schilddruesenkarzinom lag der Tg-Spiegel in 10 Faellen unterhalb des Erwartungswertes, 2 Patienten zeigten einen Tg-Wert von >1000 ng/ml. Bei Autonomien fand sich bezogen auf eine durch Substitution extrem supprimierte Vergleichsgruppe ein signifikant hoeherer mittlerer Tg-Spiegel. Aufgrund der hohen Varianz der Tg-Werte beider Kollektive war die Diagnose der Autonomie anhand der Tg-Bestimmung jedoch kaum moeglich. In der Gruppe mit Thyreoiditis Hashimoto zeigte sich im Vergleich zum Normalkollektiv ein erniedrigter Tg-Spiegel. Bei M. Basedow war die mittlere Tg-Konzentration signifikant hoeher als in der Vergleichsgruppe mit Struma diffusa, dennoch lagen 47% aller Werte noch im Referenzbereich. Schlussfolgerung: Hohe Tg-Werte fuehren bei Verdacht auf Malignitaet, Autonomie oder M. Basedow zu einer hoeheren

It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ({sup 131}I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with {sup 131}I with its nadir on day 3 of therapy (decline by 15.71 ng

    Full Text Available Background. The Chernobyl Nuclear Power Plant (CNPP accident exposed a large number of inhabitants to internal 131I radiation. The associations between internal 131I exposure and thyroid autoimmunity and benign thyroid diseases remain controversial in the population living in the contaminated area around the CNNP. In this study, we evaluate the association of 131I with benign thyroid diseases. Methods. We compared the prevalence of Anti-Thyroid Autoantibodies (ATAs, thyroid function, and prevalence of thyroid ultrasound finding outcomes in 300 residents of the contaminated area of Ukraine who were 0–5 years of age at the time of the CNPP accident (group 1 and 300 sex-matched residents who were born after the accident (group 2. Results. We did not find any differences of the prevalence of Antithyroglobulin Antibodies (TGAb positive, Antithyroid Peroxidase Antibodies (TPOAb positive, and TGAb and/or TPOAb positive between the study groups. (11.7% vs 10.3%; p = 0.602, 17.3% vs 13.0%; p = 0.136, 21.0% vs 17.3%; p = 0.254, respectively; after adjusting for age and sex, the prevalence was not associated with the 131I exposure status in the study groups. The prevalence of subclinical and overt hypothyroidism cases was not significantly different (p = 0.093 and p = 0.320 in the two groups, nor was the prevalence of goiter (p = 0.482. On the other hand, the prevalence of nodules was significantly higher in group 1 (p = 0.003, though not significantly so after adjustment for age and sex. Discussion. Working 26–27 years after the CNNP accident, we found no increased prevalence of ATAs or benign thyroid diseases in young adults exposed to 131I fallout during early childhood in the contaminated area of Ukraine. Long-term follow-up is needed to clarify the effects of radiation exposure on autoimmunity reaction in the thyroid.

    Full Text Available Abstract Background Currently, data are not available concerning a safe insufflation pressure that provides a proper view of the surgical field without adverse metabolic and hemodynamic changes in humans undergoing the robot-assisted thyroidectomy bilateral axillo-breast approach (BABA using the da Vinci robotic surgical system. The purpose of this study was to determine the optimal carbon dioxide (CO2 insufflation pressure in patients with various benign and malignant thyroid diseases when using the da Vinci robotic surgical system. Methods A total of 32 patients underwent thyroid surgery at 6 (n = 15, 9 (n = 15, and 12 (n = 2 mmHg. The partial pressure of carbon dioxide (PaCO2, pH, cardiac output, heart rate, and mean arterial pressure were measured at baseline, 30 min and 1, 1.5, and 2 hours after CO2 insufflation, and 30 min after desufflation. Results CO2 insufflation of 12 mmHg caused severe facial subcutaneous emphysema, hypercarbia, and acidosis during robot-assisted thyroidectomy with BABA. The study was stopped before completion for the patients’ safety in accordance with the study protocol. Applying 6- or 9- mmHg of CO2 insufflation pressure caused increases in PaCO2 and decreases in arterial pH. However, vital signs were stable and pH and PaCO2 were within the physiologic range during the surgery in the 6- and 9-mmHg groups. Conclusions We propose that a CO2 insufflation pressure under 10 mmHg in robot-assisted thyroidectomy with BABA is the optimal insufflation pressure for patient safety.

    Full Text Available Purpose. The aim of the study was to compare the risk of thyroid malignancy and efficacy of repeat FNA in patients with thyroid nodules diagnosed cytologically as benign lesion (BL with features of chronic thyroiditis (BL-CT and BL without CT features (BL-nCT. Methods. The analysis included 917 patients with BL-CT and 7046 with BL-nCT in the first FNA. Repeat biopsy was carried out in 787 patients of BL-CT and 5147 of BL-nCT; 218 patients of BL-CT and 2462 of BL-nCT were operated; in 88 cases of BL-CT and 563 of BL-nCT both ways of follow-up were available. Results. Outcome of repeat cytology implied surgery more frequently in patients with BL-CT than with BL-nCT—3.2% versus 1.9%, P < 0.05. Incidence of cancer (including incidentalomas was higher in patients with BL-CT operated after one benign cytology than in patients with two benign FNA outcomes: 10.8% versus 1.6%, P < 0.05. In patients with BL-nCT that difference was not significant: 3.2% versus 2.6%. Conclusions. Patients with thyroid nodules diagnosed as BL with CT features have higher risk of malignancy than patients with BL without CT features. Repeat biopsy significantly lowers percentage of FN results in patients with BL-CT in the first FNA.

    Thyroid disease does occur in the pediatric patient, and imaging plays an important role in its evaluation. A review is presented of normal development of the thyroid gland, the technique and indications for thyroid sonography, and key imaging features of congenital thyroid disorders (ectopic or absent thyroid, infantile goiter, thyroglossal duct remnants), benign thyroid masses (follicular adenoma, degenerative nodules, colloid and thyroid cysts), malignant masses (follicular, papillary and medullary carcinoma) and diffuse thyroid disease (acute bacterial thyroiditis, Hashimoto's thyroiditis, Grave's disease).

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

    Pilot studies of combined therapies treating benign nodular goiters reported promising results. The aim of this study was to investigate the effectiveness of combined microwave ablation (MWA) and radioiodine therapy (RIT) with a special focus on thyroid function at the 3-month follow-up. 15 patients (median age: 55 years) with a large goiter and benign thyroid nodules or Graves' disease were treated with the combined therapy. Serum levels of triiodothyronine (T3), thyroxine (T4), thyrotropin (TSH), thyroglobuline (Tg) and, additionally, antibody levels against thyroglobulin (TgAb), thyrotropin receptors (TRAb) and thyroid peroxidase (TPOAb) were measured at enrollment, post MWA and at the 3-month follow-up (3MFU). Furthermore, the goiter volume, I-131 dose and hospitalization time were analyzed to evaluate effectiveness. MWA was operated under local anesthesia with a system working in a wavelength field of 902 to 928 MHz. TSH, T4, T3 and Tg did not change at 3MFU, except for in two patients in whom the initial TSH levels improved to normal thyroid functioning levels at follow-up. One of the patients developed a high TRAb-level that receded back into the normal range. At 3MFU, the combined therapy showed a mean thyroid volume reduction of 26.4 ml ± 7.9 ml (30.5 % ± 4.6 % (p < 0.05)). By utilizing the combined therapy, administered activity could be reduced by 26.6 % ± 4.8 % (p < 0.05) and hospitalization time by 30.9 % ± 19.9 % (p < 0.05). The data confirmed the effectiveness of the combination of MWA with RIT. The combined therapy is an innovative and conservative approach and could become a safe alternative to surgery for the treatment of very large benign nodular goiters. Due to the short follow-up and the limited number of patients, further studies will be necessary.

    The aim of the work is to detect the frequency and the character of thyroid diseases manly with thyroid cancer diagnosed among Chernobyl clean-up workers from Latvia. Conclusions: Usually, in Latvia every year there are 2-3 thyroid cancer cases per 100 thousand inhabitants, but there are 3 cases per 5 thousands Chernobyl clean-up workers - that mean 20 times more than in general population. The first case of thyroid follicular and papillary carcinoma in the Chernobyl clean-up workers from Latvia was diagnosed after a latent period of 10 years. Among benign thyroid lesions, cystic colloid goiter and nodular colloid goiter seem to be commonly associated with radiation exposure to the thyroid gland

    To evaluate the validity and reliability of a newly-translated Thyroid-specific Patient-Reported Outcome short-form (ThyPRO-39) instrument for ethnic-Chinese patients suffering from benign thyroid diseases. The translation and cross-cultural adaptation of the English ThyPRO-39 were performed using the double forward translation, reconciliation, single backward translation, and cognitive debriefing, followed by a panel review. Cross-sectional data of 308 patients with benign thyroid diseases were utilized for this psychometric evaluation of ThyPRO-39 instrument. Convergent validity between similar construct in the ThyPRO-39, SF-6D, and SF-12v2 was assessed using Spearman correlations. The internal construct validity was assessed by corrected item-total correlations. Sensitivity of the ThyPRO-39 domain scores was determined by performing known group comparisons by independent t test. The internal consistency reliability was assessed by Cronbach's alpha coefficient. Significant floor effects were observed in 9 out of 13 domains of the ThyPRO-39. The hypothesized correlations between similar constructs in the ThyPRO-39 and the SF-12v2 and SF-6D were generally observed, supporting convergent validity. The internal construct validity was supported in most items, except eight items in six scales. Scale score of hyperthyroid symptoms of the ThyPRO-39 was significantly higher in the group with Graves' disease or hyperthyroid disease than the group without Graves' disease nor hyperthyroid disease. Scale scores of eye symptoms and impaired daily life were significantly higher in the incidental group than the non-incidental group. For six domains (hyperthyroid symptoms, hypothyroid symptoms, eye symptoms, tiredness, depressivity, and emotional susceptibility), Cronbach's alpha did not reach the recommended standard of 0.7. This was the first psychometric study to translate and adapt the ThyPRO-39 instrument for non-Caucasian patients, and report its validity and reliability

    The aim of this study was to describe the demographic characteristics and disease patterns among patients with thyroid nodular abnormalities (goiter) and benign tumors of the thyroid gland in Albania, a transitional country in South Eastern Europe. Our study included all patients diagnosed with goiter and/or benign tumors of the thyroid gland who were hospitalized at the University Hospital Center (UHC) "Mother Teresa" in Tirana between 2004 and 2012 (N=2258). All patients underwent the same examination and interviewing procedures. Demographic characteristics included gender, age, and place of residence. Binary logistic regression was used to compare the demographic characteristics between patients with benign tumors of the thyroid gland and those with goiter. Overall, there were 2204 patients with goiter and 54 patients with benign tumors of the thyroid gland hospitalized at UHC over the period 2004-2012. There was no evidence of statistically significant differences in demographic characteristics (age, gender, or place of residence) between patients with benign tumors of the thyroid gland and those with goiter. Our study provides useful evidence on the epidemiology of benign tumors of the thyroid gland and the thyroid nodular abnormalities (goiter) in the Albanian population. Future studies in Albania should assess the main determinants of thyroid gland disorders and compare them with findings pertinent to other similar populations.

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

    2005-01-01

    In the last 15 years, several concepts have been developed to further improve the outcome of radioiodine therapy in functional thyroid autonomy. Results of radioiodine therapy in functional autonomy are considerably better than in Graves' disease. All of the currently-applied concepts offer healing rates of 75-100%, but they differ considerably in the hypothyreosis rates attained. The target volume can be precisely determined by sonography only in unifocal autonomy. In the case of multifocal and disseminated autonomy, the entire thyroid is taken as the target volume and the focal dose is reduced ('dosimetric compromise'). TcTUs-based dose concepts calculate the functionally autonomous volume from the TcTUs and replace the target volume by sonography, in the TcTUs-adapted dose concepts, sonographic target volume is left and the focal dose varied in dependence of the suppression uptake. The objective is to attain a high rate of success with a low rate of hypothyreosis. (orig.)

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

    Fine-needle aspiration cytology is the standard technique to diagnose thyroid pathologies. However, this method results in a high percentage of inconclusive and false negatives. The use of time-resolved fluorescence techniques to detect biochemical composition and tissue structure alterations could help to develop a portable, minimally invasive, and nondestructive method to assist during surgical procedures. This study aimed to use fluorescence lifetimes to differentiate healthy and benign tissues from malignant thyroid tissue. The thyroid tissue was excited at 298-300 nm and the fluorescence decay registered at 340 and 450 nm. We observed fluorescence lifetimes at 340 nm emission of 0.80±0.26 and 3.94±0.47 ns for healthy tissue; 0.90±0.24 and 4.05±0.46 ns for benign lesions; and 1.21±0.14 and 4.63±0.25 ns for malignant lesions. For 450 nm emissions, we obtain lifetimes of 0.25±0.18 and 3.99±0.39 ns for healthy tissue, 0.24±0.17 and 4.20±0.48 ns for benign lesions, 0.33±0.32 and 4.55±0.55 ns for malignant lesions. Employing analysis of variance, we differentiate malignant lesions from benign and healthy tissues. In addition, we use quadratic discriminant analysis to distinguish malignant from benign and healthy tissues with an accuracy of 76.1%, sensitivity of 74.7%, and specificity of 83.3%. These results indicate that time-resolved fluorescence can assist medical evaluation of thyroid pathologies during surgeries.

    Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck. This editorial reviews the use of various sclerotic agents and application of sclerotherapy to benign cystic diseases in the neck.

    Although there have been few studies concerning BPPV and thyroid autoimmunity and a positive relation was found between them, this study didn't find any relation between BPPV and thyroid autoimmunity. IT is thought that further large-scale studies must be done to clarify the relation. Benign paroxysmal positional vertigo (BPPV) consists of ∼ 20% of vestibular disorders. Self-limited rotatory nystagmus with positional vertigo are the main findings of BPPV. Although canalolithiasis theory was confirmed by demonstrating freely floating debris in the endolymph of the posterior semicircular channel in following studies, currently, the etiology hasn't been explained totally. This study investigated the relation of BPPV and thyroid autoimmunity evaluated via measurement of serum thyroid autoantibodies. Fifty patients (37 female, 13 male) with BPPV (BPPV group), 52 patients (40 female, 12 male) with non-BPPV vertigo (non-BPPV group) and 60 otherwise normal control (38 female, 22 male) samples were enrolled in the study. All samples of BPPV, non-BPPV groups and controls had undergone a cochleovestibular test following thorough ENT examination. After blood samples were drawn from each subject, thyroid-stimulating hormone (TSH), anti-thyroid peroxidase antibody (TPO-Ab) and anti-thyroglobulin antibody (TG-Ab) levels were measured accordingly. In the study, eight patients of the BPPV group (16%) had a high thyroid antibody level. In the non-BPPV group, six patients (11.5%) had elevated thyroid antibodies. In the control group, 15 patients (25%) had elevated thyroid antibodies. TSH values of all subjects were detected to be within normal range. No statistical difference was found between the groups with respect to TG-Ab and TPO-Ab values (p-values = 0.729 and 0.812, respectively).

    Objective: To determine the frequencies of various benign breast diseases (BBD) in female patients in three private hospitals of Hyderabad. Methodology: This is a prospective cohort study of all female patients visiting the surgical clinic with breast problems. This study was conducted at Isra University Hospital Hyderabad and two other private hospitals of Hyderabad over a period of about three years starting from March 2004 to February 2007. All female patients visiting the surgical clinic with breast problems were included in the study. Patients with obvious clinical features of malignancy or those who on work up were diagnosed as carcinoma were excluded from the study. Results: A total of 275 patients were included in the study. About 44% (120/275) patients belonged to third decade of life (age between: 21-30 years) followed by 33% from forth decade (age between: 31- 40 years). Fibroadenoma was the most common benign breast disease, seen in 27% (75/275) of patients, followed by fibrocystic disease seen in about 21% (57/275) patients. Conclusion: Benign Breast Diseases (BBD) are common problems in females of reproductive age. Fibroadenoma is the commonest of all benign breast disease in our set up mostly seen in second and third decade of life. Fibrocystic disease of the breast is the next common BBD whose incidence increases with increasing age. (author)

    Ephrin receptors (Ephs) are frequently overexpressed in a wide variety of human malignant tumors, being associated with tumor growth, invasion, metastasis and angiogenesis. The aim of the present study was to evaluate the clinical significance of Eph-A2 and Eph-A4 expression in human benign and malignant thyroid lesions. Eph-A2 and Eph-A4 protein expression was assessed immunohistochemically on paraffin-embedded thyroid tissues from 131 patients with benign and malignant lesions. Eph-A2 was significantly overexpressed in malignant compared to benign thyroid lesions (p<0.001). Papillary carcinoma cases presented significantly increased Eph-A2 expression compared to those with hyperplasia nodules (p<0.001). Eph-A4 expression was not differentiated between cases with malignant or benign thyroid lesions. Papillary carcinoma cases presented significantly increased Eph-A4 expression compared to those with hyperplasia nodules (p=0.006). In the subgroup of malignant thyroid lesions, Eph-A2 and Eph-A4 expression was not associated with TNM stage, capsular, lymphatic or vascular invasion. The present data suggest that Eph-A2, but not Eph-A4, overexpression may be associated with the malignant transformation of thyroid neoplasia. Further studies conducted on cohorts including a higher proportion of patients with advanced nodal and metastatic disease are recommended to draw definite conclusions on the clinical significance of Eph proteins in thyroid neoplasia.

    Nodular goiter is one of the most common benign lesions in thyroid nodule. The main treatment of the disease is still the traditional surgical resection, however there are many problems such as general anesthesia, surgical scar, postoperative thyroid or parathyroid function abnormalities, and high nodules recurrence rate in residual gland. The purpose of this study was to compare the efficacy, safety, and cost-effectiveness of 2 treatment methods, surgery and radiofrequency ablation, for the treatment of benign thyroid nodules. From May 2012 to September 2013, 200 patients with nodular goiters who underwent surgery (group A) and 200 patients treated by radiofrequency ablation (group B) were enrolled in this study. Inclusion criteria were the following: 1) cosmetic problem, 2) nodule-related symptoms, 3) hyperfunctioning nodules related to thyrotoxicosis, and 4) refusal of surgery (for group B). An internally cooled radiofrequency ablation system and an 18-ga internally cooled electrode were used. We compared the 2 groups in terms of efficacy, safety, and cost-effectiveness during a 1-year follow-up. After radiofrequency ablation, the nodule volume decreased significantly from 5.4 to 0.4 mL (P = .002) at the 12-month follow-up. The incidence of complications was significantly higher from surgery than from radiofrequency ablation (6.0% versus 1.0%, P = .002). Hypothyroidism was detected in 71.5% of patients after surgery but in none following radiofrequency ablation. The rate of residual nodules (11.9% versus 2.9%, P = .004) and hospitalization days was significantly greater after surgery (6.6 versus 2.1 days, P radiofrequency ablation are both effective treatments of nodular goiter. Compared with surgery, the advantages of radiofrequency ablation include fewer complications, preservation of thyroid function, and fewer hospitalization days. Therefore, radiofrequency ablation should be considered a first-line treatment for benign thyroid nodules. © 2015 by American

    It is generally considered impossible to differentiate follicular carcinomas from follicular adenomas by means of ultrasonography or cytology before surgery. Therefore, follicular carcinoma is histopathologically diagnosed by verifying capsular and/or vascular invasion after surgery. However, ultrasonography may play an important role in diagnosing follicular carcinoma preoperatively in a small number of cases. Four cases of follicular carcinoma or follicular neoplasm that transformed from a benign thyroid tumor and demonstrated a "nodule in nodule" appearance on ultrasonography are presented in this report. Characteristic ultrasound features of such patients are: (1) a "nodule in nodule" appearance, (2) a well-defined boundary line between the nodules, and (3) separate distribution of blood signals within each nodule. A small number of patients with follicular carcinomas or follicular neoplasms may present with a "nodule in nodule" appearance on ultrasonography. It was suggested a long time ago that follicular carcinomas may develop from benign thyroid tumors. The fact that follicular carcinomas appear within benign tumors may be evidence of thyroid tumorigenesis.

    A descriptive and prospective study on the practice of ambulatory major surgery to eliminate benign tumours of the thyroid gland, was carried out in the General Surgery Service of 'Dr. Joaquin Castillo Duany' Teaching Clinical Surgical Hospital in Santiago de Cuba during the years 1996-2008, both included, through a previous clinical evaluation of 74 patients in the Endocrinology Outpatient Department, where it was decided that they could definitely have a surgical treatment. The female sex, the age groups from 31 to 45 years, the hemithyroidectomy as surgical technique, acupuncture as analgesic procedure and the follicular adenoma as cytohistological result prevailed in the case material. Mild complications occurred in 5 members of the sample, but recovery was absolute in all, so that even 72 of them were discharged before the 24 hours. Due to its good acceptance, this surgical method is beneficial for patient and hospital institutions.(author)

    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.

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

Patients with hypothyroidism taking thyroxine can take their tablets on an empty stomach at bedtime instead of half an hour before Sehr. Patients with hyperthyroidism, on methimazole/carbimazole can continue their dose in once or twice daily regimes, while those on propylthiouracil need to be switched. Hyperthyroid patients with severe symptoms should start treatment immediately and can avoid fast for few days after a consultation with their religious scholar.

    Full Text Available Objective: This study aims to investigate the role of IGF-1 in the development of nodular thyroid disease. Material and Methods: A total number of 100 consecutive patients operated for nodular thyroid disease in our institution were included in this prospective study. In addition to classical pathological examinations, nodules and extranodular healthy tissues were sampled and immunochemically stained for IGF-1. The materials were independently evaluated using an Allred Scoring System ranging from 0 to 8. If the score was ≥1, the tissue was accepted as IGF-1 positive.Results: IGF-1 positivity was observed in 88% and 58% of the samples obtained from nodules and extranodular healthy tissues, respectively. Allred 8-unit scores were higher in benign nodules (n=89; 4.1±2.3 and papillary carcinomas (n=7; 6.7±1.3, than in extranodular healthy tissues in the same patients (2.3±2.3 and 3.3±1.9, respectively; and higher in papillary carcinomas than in benign nodules, when the scores were compared to each other (p<0.01 for all comparisons. Conclusions: Allred 8-unit scores for IGF-1 increase in the presence of benign thyroid nodules, papillary cancer. The results of our study support the findings of previous studies demonstrating the role of IGF-1 in the development of thyroidal nodules.

    Surgical excision has traditionally been the treatment of choice for benign non-thyroid cystic neck masses, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, and parathyroid cyst. However, there is a tendency toward recurrence after surgery, and surgery may be accompanied by complications, including nerve injuries, vascular injuries, and scar formation. Ultrasound-guided sclerotherapy using various agents has been challenged and successfully applied as an alternative treatment for benign non-thyroid cystic neck masses. This report reviews the available sclerosing agents and describes the applications of sclerotherapy to the treatment of benign cystic masses in the neck.

    Sonoelastography is a new ultrasound method which could be helpful to determine which thyroid nodule is malignant. We designed this study to evaluate the accuracy of sonoelastography in differentiating of benign and malignant thyroid nodules in Iranian patients. Forty thyroid nodules in forty consecutive patients who had been referred for sonography-guided fine-needle aspiration biopsy were evaluated. Gray scale ultrasound and elastosonography by real-time, freehand technique applied for all patients. Elastography findings were classified into four groups. Nodules which were classified as patterns 1 or 2 in elastogram evaluation were classified as benign and probably malignant if elastogram scans were patterns 3 and 4 of elastogram scan. Mean age ± standard deviation (SD) was 42.2 ± 12.6 years, and mean ± SD thyroid-stimulating hormone level was 1.4 ± 1.9 IU/ml. Thirty-five cases (87.5%) were female and 5 (12.5%) were male. Histological examination indicated 27 (67.5%) benign and 13 (32.5%) malignant nodules. The most elastogram score was 2 (50%) followed by score 3. The cut-off point of 2 considered as the best value to differentiate benign and malignant thyroid nodules with sensitivity and specificity of 61% and 78% (area under the curve = 0.76, 95% confidence interval: 0.6-0.92, P = 0.007). Sonoelastography could help to differentiate benign and malignant thyroid nodules. As our sample size was limited, larger studies are recommended.

    Autoimmune thyroid disease (AID) with reversible thyroid dysfunction was classified mainly by etiology. Hashimoto thyroiditis itself, pregnancy, cytokine therapy and various drugs, iodine-rich food and AID with TSH receptor antibody (TRAb) were main items. Silent or painless thyroiditis which was termed destructive thyroiditis occurs without clear cause or after adrenectomy for Cushing syndrome. Abnormal human chorionic gonadotropin (hCG) rarely causes transient thyrotoxicosis at early phase of pregnancy and postpartum thyroiditis which has similar symptom as silent thyroiditis is relatively common disorders. Thyroid dysfunction of patients with both TRAb (TSAb and TSBAb) is pathophysiologically unknown and the detection of both antibodies in a patient serum is difficult methodologically. We developed the highly sensitive TSAb assay by patients' IgG precipitated by high concentration PEG (22.5%) using porcine thyroid cell. This assay is also useful for detection of the coexistence cases of TSAb and TSBAb.

    Dizziness is a frequent complaint of patients with Parkinson's disease (PD), and orthostatic hypotension (OH) is often thought to be the cause. We studied whether benign paroxysmal positional vertigo (BPPV) could also be an explanation. To assess the prevalence of benign paroxysmal positional vertigo in patients with Parkinson's disease, with and without dizziness. 305 consecutive outpatients with PD completed the Movement Disorders Society-sponsored revision of the Unified Parkinsons' Disease Rating Scale-motor score, the Dizziness Handicap Inventory, the Dix-Hallpike maneuver and a test for orthostatic hypotension. When positive for benign paroxysmal positional vertigo, a repositioning maneuver was performed. Patients were followed for three months to determine the clinical response. 305 patients responded (186 men (61%), mean age 70.5 years (Standard Deviation 9.5 years)), of whom 151 (49%) complained of dizziness. 57 (38%) of the dizzy patients appeared to have orthostatic hypotension; 12 patients (8%) had a classical but previously unrecognized benign paroxysmal positional vertigo. A further four patients (3%) had a more atypical presentation of benign paroxysmal positional vertigo. Three months after treatment, 11 (92%) of patients with classical benign paroxysmal positional vertigo were almost or completely without complaints. We found no 'hidden' benign paroxysmal positional vertigo among patients without dizziness. The prevalence of benign paroxysmal positional vertigo among all patients with PD was 5.3%. Among Parkinson patients with symptoms of dizziness, up to 11% may have benign paroxysmal positional vertigo, which can be treated easily and successfully. Crown Copyright © 2013.

    The search for a specific marker that could help to distinguish between differentiated thyroid carcinoma and benign lesions remains elusive in clinical practice. Heparanase (HPSE) is an endo-beta-glucoronidase implicated in the process of tumor invasion, and the heparanase-2 (HPSE2) modulates HPSE activity. The aim of this study was to evaluate the role of heparanases in the development and differential diagnosis of follicular pattern thyroid lesions. HPSE and HPSE2 expression by qRT-PCR, immunohistochemistry evaluation, western blot analysis and HPSE enzymatic activity were evaluated. The expression of heparanases by qRT-PCR showed an increase of HPSE2 in thyroid carcinoma (P = 0.001). HPSE activity was found to be higher in the malignant neoplasms than in the benign tumors (P<0.0001). On Western blot analysis, HPSE2 isoforms were detected only in malignant tumors. The immunohistochemical assay allowed us to establish a distinct pattern for malignant and benign tumors. Carcinomas showed a typical combination of positive labeling for neoplastic cells and negative immunostaining in colloid, when compared to benign tumors (P<0.0001). The proposed diagnostic test presents sensitivity and negative predictive value of around 100%, showing itself to be an accurate test for distinguishing between malignant and benign lesions. This study shows, for the first time, a distinct profile of HPSE expression in thyroid carcinoma suggesting its role in carcinogenesis.

    Indirect thyroid lymphography with water-soluble radiographic agents has been applied. This method allows contrast lymph microvessels of the thyroid gland, providing the detection of volume formations of 0.3 to 0.4 cm and more in diameter. 232 patients with different thyroid diseases were examined. Different rate of the water-soluble contrast agent resolution in diffuse toxic and nodular goiter, thyroid cancer, chronic thyroiditis is of great importance in differential diagnosis of these diseases. This method provides necessary information on the organs inner structure, its topography and size [ru

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

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

    To determine the diagnostic accuracy of Diffusion-Weighted Imaging (DWI) and Apparent Diffusion Coefficient (ADC) mapping in differentiating benign from malignant thyroid nodules by taking histopathology as the gold standard. Study Design:Across-sectional analytical study. Place and Duration of Study: Department of Radiology at Combined Military Hospital (CMH), Lahore, from August 2012 to July 2013. Methodology: Thirty-five patients, who were referred to radiology department of CMH, Lahore, for ultrasound or Fine Needle Aspiration Cytology (FNAC) of thyroid gland, fulfilling the inclusion and exclusion criteria, were included in the study. They were evaluated on 1.5 Tesla MRI machine with T1- and T2-weighted imaging as well as fat-suppressed technique. DWI was done using b-values of 0 and 1000 s/mm2 and ADC values were calculated for the thyroid nodules. All of these patients were subjected to ultrasound guided core biopsy and histopathology results were correlated with ADC values. Results: The benign nodules showed facilitated diffusion while malignant nodules showed restricted diffusion. T-test was used to assess the difference in mean ADC values between benign and malignant nodules. The mean ADC value of the malignant thyroid nodules (0.94 ± 0.16 x 10/sup -3/mm2/s) was significantly lower than that of the benign thyroid nodules (1.93 ±0.13 x 10/sup -3/mm2/s) (p-value < 0.05). ADC value of 1.6 x 10/sup -3/mm2/s was used as a cut-off, for differentiating benign from malignant thyroid nodules. The sensitivity, specificity, PPV, NPV and diagnostic accuracy of DWI and ADC values in differentiating benign from malignant thyroid nodules were 93%, 95%, 93%, 95% and 92.3%, respectively. Conclusion: DWI is a non-invasive diagnostic tool for characterization and differentiation between benign and malignant thyroid nodules. It not only decreases the burden of unnecessary surgeries when pre-operative FNAC and biopsy are inconclusive, but is also helpful in reaching a

    The objective of the present study was to investigate the effectiveness and safety of ultrasound-guided microwave ablation in the treatment of benign thyroid nodules. A total of 474 benign thyroid nodules in 435 patients who underwent ultrasound-guided microwave ablation from September 2012 to August 2015 were included. Nodule volume and thyroid function were measured before treatment and at 1, 3, 6, and 12 months and subsequently after every 6 months. The nodule volume reduction rate and changes of thyroid function were evaluated. The volume of all thyroid nodules significantly decreased after ultrasound-guided microwave ablation. The average volume was 13.07 ± 0.95 ml before treatment, and 1.14 ± 0.26 ml at 12-months follow-up. The mean volume reduction rate was 90% and the final volume reduction rate was 94%. The volume reduction rate of mainly cystic nodules was significantly higher than that of simple solid and mainly solid nodules (all P microwave ablation is an effective and safe technique for treatment of benign thyroid nodules, and has the potential for clinical applications. Impact statement Ultrasound-guided MWA is an effective and safe technique for the treatment of benign thyroid nodules. It can significantly reduce the nodule volume, improve the patients' clinical symptoms, has less complication, guarantees quick recovery, meets patients' aesthetic needs, and shows less interference on the physiological and psychological aspects of the body. MWA should be a good complement to traditional open surgery and has potentials in clinical applications.

    Full Text Available A 70-year-old female, with a history of progressive dyspnoea, was admitted to the critical care unit after successful resuscitation following a witnessed, out of hospital cardiorespiratory arrest. A presumptive diagnosis of cardiorespiratory arrest secondary to an exacerbation of chronic obstructive pulmonary disease was made. However, on more detailed examination a large anterior, midline neck mass was noted. Following tracheal intubation, a computerised tomography scan of the patient’s neck and thorax revealed a seven-centimetre, well-defined, nonenhancing, rounded homogeneous opacity at the thoracic inlet, consistent with a large midline thyroid cyst. Needle aspiration of the cyst was performed and yielded approximately 50 mL of frank blood. After an uncomplicated tracheal extubation and recovery, an elective subtotal thyroidectomy was performed prior to hospital discharge. Histology of the specimen revealed a benign thyroid cyst within a multinodular goitre. Euthyroid multinodular goitres are more likely to be managed conservatively due to an asymptomatic clinical course in most patients. However, the risk of respiratory distress and acute airway obstruction from tracheal compression or acute haemorrhage should be kept in mind. Patients at risk of this life threatening complication should be managed with elective thyroidectomy to reduce morbidity and mortality.

    Hysterectomy is one of the most common gynaecological surgical procedures performed but there appears to be a decline in the performance of this procedure in Ireland in recent times. We set out to establish the extent of the decline of hysterectomy and to explore possible explanations. Data for hysterectomy for benign disease from Ireland was obtained from the Hospital In-Patient Enquiry Scheme (HIPE) section of the Economic and Social Research Institute for the years 1999 to 2006. The total number of hysterectomies performed for benign disease showed a consistent decline during this time. There was a 36% reduction in the number of abdominal hysterectomy procedures performed.

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

    Recent developments have resulted in important changes in the diagnosis and management of thyroid diseases. Fine-needle aspiration biopsy has now supplanted imaging studies as the initial procedure for differentiating malignant from benign thyroid nodules. However, thyroid scintigraphy may be helpful in the management of patients without a definitive result of cytology and in Grave's disease with a nodule found in ultrasound scanning. On the other hand, scintigraphy remains critical for the determination of autonomously functioning tissue, and hyperthyroidism (over or subclinical) is an indisputable indication for scintigraphy in patients with a thyroid nodule. Besides, radionuclide scanning has retained its significance in the diagnosis of ectopic thyroid tissue, in the monitoring effects of radioiodine therapy, and in the evaluation of relapses in patients treated by surgery for benign thyroid diseases. The 131 I scintigraphy is commonly used in the postoperative follow-up of patients with the differentiated thyroid carcinoma, although the role of this procedure in management of the disease may change in the near future. Nowadays, the 123 I thyroid scintigraphy has been proposed as a safe and clinically important procedure for accurately counselling patients with congenital hypothyroidism. Moreover, the problem of underestimation of thyroid scintigraphy in diagnosis and management of benign diseases of gland in some regions of Poland has also been discussed. (author)

    Full Text Available Abstract Background Clinicians are confronted with an increasing number of patients with thyroid nodules. Reliable preoperative diagnosis of thyroid nodules remains a challenge because of inconclusive cytological examination of fine-needle aspiration biopsies. Although molecular analysis of thyroid tissue has shown promise as a diagnostic tool in recent years, it has not been successfully applied in routine clinical use, particularly in Chinese patients. Methods Whole-transcriptome sequencing of 19 primary papillary thyroid cancer (PTC samples and matched adjacent normal thyroid tissue (NT samples were performed. Bioinformatics analysis was carried out to identify candidate diagnostic genes. Then, RT-qPCR was performed to evaluate these candidate genes, and four genes were finally selected. Based on these four genes, diagnostic algorithm was developed (training set: 100 thyroid cancer (TC and 65 benign thyroid lesions (BTL and validated (independent set: 123 TC and 81 BTL using the support vector machine (SVM approach. Results We discovered four genes, namely fibronectin 1 (FN1, gamma-aminobutyric acid type A receptor beta 2 subunit (GABRB2, neuronal guanine nucleotide exchange factor (NGEF and high-mobility group AT-hook 2 (HMGA2. A SVM model with these four genes performed with 97.0 % sensitivity, 93.8 % specificity, 96.0 % positive predictive value (PPV, and 95.3 % negative predictive value (NPV in training set. For additional independent validation, it also showed good performance (92.7 % sensitivity, 90.1 % specificity, 93.4 % PPV, and 89.0 % NPV. Conclusions Our diagnostic panel can accurately distinguish benign from malignant thyroid nodules using a simple and affordable method, which may have daily clinical application in the near future.

    The aim of this study was to evaluate the diagnostic utility of the virtual touch tissue quantification (VTQ) technology for differentiating between benign and malignant thyroid nodules. 198 nodules (168 benign and 30 malignant nodules) identified in 164 patients with available VTQ velocity data and fine-needle aspiration cytology or post-surgical pathological results were included. The VTQ velocities of nodules and adjacent thyroid tissue were examined. Malignant nodules had a significantly higher VTQ velocity (3.06 ± 1.04 m/s, range: 1.90-6.46 m/s) than that of benign nodules (2.40 ± 0.85 m/s, range: 0.69-8.09 m/s) (p = 0.002). The VTQ velocity ratio between malignant nodules and adjacent thyroid tissue (1.39 ± 0.43, range: 0.89-2.65) was also statistically higher than that of benign nodules (1.15 ± 0.44, range: 0.26-3.47) (p = 0.008). The area under the receiver operating characteristic curve for the VTQ velocity was 0.72 with a cutoff point of 2.37 m/s and that of the VTQ velocity ratio was 0.68 with a cutoff point of 1.26. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for the VTQ velocity were 86.7%, 50.6%, 23.9%, 95.5%, and 56.1%, respectively and 60.0%, 72.0%, 27.7%, 91.0%, and 70.2%, respectively for the VTQ velocity ratio.

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

    While there is very good epidemiological evidence for induction of thyroid cancer by radiation exposure in children, the risk for adults after exposure is still uncertain, especially when concerning relatively small radiation doses. A cohort of 27415 persons which in 1950 through 1964 had received x-ray treatment for various benign disorders in the locomotor system (such as painful arthrosis and spondylosis) was selected from three hospitals in Northern Sweden. A proportion of this cohort, consisting of 8144 persons (4075 men and 4069 women), had received treatment to the cervical spine and thereby received an estimated average dose in the thyroid gland of about 1 Gy. Standard incidence rates (SIR) were calculated by using the Swedish Cancer Register. In the cervical spine cohort, 22 thyroid cancers were found versus 13.77 expected (SIR 1.60; CI 1.00-2.42). The corresponding figures for women were 16 observed cases versus 9.60 expected cases (SIR 1.67; CI 0.75-2.71). Most thyroid cancers (15 out of 22) were diagnosed >15 years after the exposure. In the remaining part of the total cohort, i.e. those without cervical spine exposure, no increased risk of thyroid cancer was found (SIR 0.98; CI 0.64-1.38). The study strongly suggests that external radiation exposure of adults at relatively small doses increases the risk of thyroid cancer but also that this increase is very much lower than that reported after exposure in children

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

    Full Text Available HBME-l is an antimesothelial monoclonal antibody that recognizes an unknown antigen on microvilli of mesothelial cells. The antibody is only relatively specific for mesothelium and is used in the differential diagnosis of mesothelioma and adenocarcinoma within the context of an appropriate immuno-histochemical panel. HBME-l has also been reported to strongly and uniformly stain papillary and follicular carcinoma of the thyroid while benign disorders have been usually negative. We studied the immunoreactivity of HBME-l in 90 cases of benign and malignant thyroid lesions. We found strong positive staining in the majority of papillary carcinomas (28/31, in some of follicular carcinomas (4/6,and in a few follicular adenomas (2/17. Negative staining was found in oxyphilic cell adenoma (0/4, nodular goiter (0/13 and undifferentiated carcinoma. The results suggest that monoclonal antibody HBME-l is useful in differentiating papillary and follicular carcinoma of the thyroid from benign lesions, especially in more differentiated lesions. Strong and generalized immunoreactivity for HBME-l in a follicular lesion should raise the suspicion of malignancy, but negative staining specially in poorly differentiated lesion does not rule out malignancy.

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

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren's disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

    In the treatment of benign thyroid nodules, ethanol ablation (EA), and radiofrequency ablation (RFA) have been suggested for cystic and solid thyroid nodules, respectively. Although combining these ablation techniques may be effective, no guidelines for or reviews of the combination have been published. Currently, there are three ways of combining EA and RFA: additional RFA is effective for treatment of incompletely resolved symptoms and solid residual portions of a thyroid nodule after EA. Additional EA can be performed for the residual unablated solid portion of a nodule after RFA if it is adjacent to critical structures (e.g., trachea, esophagus, and recurrent laryngeal nerve). In the concomitant procedure, ethanol is injected to control venous oozing after aspiration of cystic fluid prior to RFA of the remaining solid nodule.

    Objective: To explore the value of gemstone spectral imaging (GSI) in the detection and differential diagnosis of benign and malignant thyroid nodules. Methods: The spectral CT images in 88 patients with thyroid nodules were analyzed retrospectively. All the patients underwent spectral CT scanning, including 33 patients undergoing biphase enhanced CT imaging. Nodules were divided into benign and malignant ones according to histopathologic results. The iodine concentration, slope of spectral curve, effective atomic number in non-enhanced and enhanced scanning were compared between benign and malignant group by the Wilcoxon rank sum test, respectively. The optimal iodine concentration threshold to predict malignancy was obtained by receiver operating characteristic curve (ROC), sensitivity and specificity were achieved. Results: A total of 106 nodules were detected, including 76 benign and 30 malignant nodules. In non-contrast CT imaging, the average iodine concentration, slope of spectral curve, effective atomic number of were 2.35 × 100 μg/ml, 0.29 and 7.71 for benign group: -0.51 × 100 μg/ml, -0.06 and 7.52 for malignant group (Z value were -3.072, -3.107 and -3.055, respectively; P<0.05). In the arterial phase, the average iodine concentration, slope of spectral curve, effective atomic number of the two group were 27.22 × 100 μg/ml, 3.23 and 9.10 for benign group; 18.81 × 100 μg/ml, 2.24 and 8.69 for malignant group (Z value were -2.582, -2.582 and -2.564, respectively; P<0.05). In venous phase,no significant difference was found for each parameter between the two groups (P>0.05). The optimal iodine concentration to predict malignancy was -0.35 × 100 μg/ml in non-enhanced phase with 56.7% sensitivity and 73.7% specificity. The optimal iodine concentration was 22.91 × 100 μg/ml in arterial phase, with 76.2% sensitivity and 75.0% specificity. Using iodine concentration to predict malignancy in both non-contrast phase and arterial phase, the sensitivity

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

    There are several interactions between thyroid and kidney functions in each other organ's disease states. Thyroid hormones affect renal development and physiology. Thyroid hormones have pre-renal and intrinsic renal effects by which they increase the renal blood flow and the glomerular filtration rate (GFR). Hypothyroidism is associated with reduced GFR and hyperthyroidism results in increased GFR as well as increased renin – angiotensin – aldosterone activation. Chronic kidney disease (CKD) ...

    This study investigated the association of serum B-lymphocyte activating factor (BAFF) levels with autoimmune thyroid disease (AITD) in a Chinese population. We enrolled 221 patients with AITD [170 patients with Graves' disease (GD), 51 patients with Hashimoto's thyroiditis (HT)], and 124 healthy controls. Serum BAFF levels, thyroid function and thyroid autoantibody (TAb) levels, including of thyroid-stimulating hormone receptor antibody (TSHRAb), anti-thyroid peroxidase antibody (Anti-TPO Ab), and antithyroglobulin antibody (ATA), were measured at baseline. Serum BAFF levels were higher in the GD, HT, and AITD groups than in the control group. Significant correlations were observed between BAFF and TSHRAb levels (r=0.238, p=0.018), between BAFF and Anti-TPO Ab levels (p=0.038), and between BAFF and ATA titers (p=0.025) in women but not in men. In addition, serum BAFF levels were significantly associated with free thyroxine (r=0.430, p=0.004) and TSHRAb (r=0.495, p=0.001) levels in women with active GD but not in those with inactive GD. Serum BAFF levels are increased in GD, HT, and AITD. The correlation between serum BAFF and TAb levels exhibits a dimorphic pattern, particularly in active GD. Copyright © 2016 Elsevier B.V.

    X-ray should only be applied when other forms of treatment of good-natured diseases do not provide equally good results. One should note that somatic lesion should be completely avoided and genetic lesion avoided to the greatest probability. One can distinguish according to ones aims between inflammation irradiation, pain irradiation, stimulation therapy and functional therapy. An indication for inflammation irradiation can be post-operative parotitis, furuncle in the face, mastitis puerperalis, panaritium ossale, recurrent sudoriparouns abscesses and repelling reactions after transplanting organs. Pain irradiation is indicated with degenerative diseases of the skeleton system. A further possible application is radiotherapy of hypotrophic processes and benign tumours. Functional radiotherapy is indicated with hyperendocrinism, neurovegetative disorders and allergies. (MG) [de

  16. Radiotherapy of benign diseases in Berlin (West)

    International Nuclear Information System (INIS)

    1. In Berlin (West), X-ray therapy was applied during the year 1973 in 18 hospitals and by 33 practicing physicians. The 3rd quarter of the year 1973 was taken as basis for the frequency of therapeutic X-ray application. From a total of 15912 patients, 9432 were X-rayed on account of malignant diseases, 6480 because of benigne diseases. This number definitely surpasses the number of cases treated in Munich by X-ray therapy. In Berlin, this might be connected to the age structure. 2. Utilizing the quotations and calculations put down in the report about the effect of atomic radiation by the Scientific Committee of the United Nations, and the values quoted for gonadal doses in the literature, a total-GSD-value of 0.82 +- 0.2 mrem/a was calculated for hospitals and practicing physicians in Berlin. In spite of higher frequencies, this value is approximately of the same order of magnitude as the values calculated for Munich for the year 1971 by I. and H.P. Schmelz. 3. The total-GSD-value for the population of the Federal Republic of Germany resulting from artificial radiation exposure during 1976 is reported to be approximately 60 mrem. Thus, the GSD-value for the X-ray therapy of benign diseases lies approximately at 1.3% and should be of minor significance for radiation-hygienic reflections. 4. Of primary concern is still the radiation exposure to individual patients. Because of possible secondary effects, X-ray therapy for keloids and hemangiomas in infancy and youth are of particular significance. For this reason, its proportion to GSD is also in Berlin relatively large. (orig.) [de

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

  19. MIR141 expression differentiates Hashimoto Thyroiditis from PTC and benign thyrocytes in Irish archival thyroid tissues

    Full Text Available MicroRNAs (miRNAs are small non-coding RNAs approximately 22 nucleotides in length that function as regulators of gene expression. Dysregulation of miRNAs has been associated with initiation and progression of oncogenesis in humans. Our group has previously described a unique miRNA expression signature, including the MIR200 family member MIR141, which can differentiate papillary thyroid cancer (PTC cell lines from a control thyroid cell line. An investigation into the expression of MIR141 in a series of archival thyroid malignancies (n=140; classic PTC, follicular variant PTC, follicular thyroid carcinoma (FTC, Hashimoto thyroiditis (HT, or control thyrocytes was performed. Each cohort had a minimum of 20 validated samples surgically excised within the period 1980 - 2009. A subset of the HT and cPTC cohorts (n=3 were also analysed for expression of TGFβR1, a key member of the TGFβ pathway and known target of MIR141. Laser capture microdissection was used to specifically dissect target cells from formalin-fixed paraffin-embedded archival tissue. Thyrocyte- and lymphocyte-specific markers (TSHR and LSP1 respectively confirmed the integrity of cell populations in the HT cohort. RNA was extracted and quantitative RT-PCR was performed using comparative CT (ΔΔCT analysis. Statistically significant (p<0.05 differential expression profiles of MIR141 were found between tissue types. HT samples displayed significant downregulation of MIR141 compared to both classic PTC and control thyrocytes. Furthermore, TGFβR1 expression was detected in cPTC samples but not in HT thyrocytes. It is postulated that the down-regulation of this miRNA is due, at least in part, to its involvement in regulating the TGFβ pathway. This pathway is exquisitely involved in T-cell autoimmunity and has previously been linked with HT. In conclusion, HT epithelium can be distinguished from cPTC epithelium and control epithelium based on the relative expression of MIR141.

  20. Celiac disease and autoimmune thyroid disease.

    Celiac disease (CD) or gluten sensitive enteropathy is relatively common in western populations with prevalence around 1%. With the recent availability of sensitive and specific serological testing, many patients who are either asymptomatic or have subtle symptoms can be shown to have CD. Patients with CD have modest increases in risks of malignancy and mortality compared to controls. The mortality among CD patients who comply poorly with a gluten-free diet is greater than in compliant patients. The pattern of presentation of CD has altered over the past three decades. Many cases are now detected in adulthood during investigation of problems as diverse as anemia, osteoporosis, autoimmune disorders, unexplained neurological syndromes, infertility and chronic hypertransaminasemia of uncertain cause. Among autoimmune disorders, increased prevalence of CD has been found in patients with autoimmune thyroid disease, type 1 diabetes mellitus, autoimmune liver diseases and inflammatory bowel disease. Prevalence of CD was noted to be 1% to 19% in patients with type 1 diabetes mellitus, 2% to 5% in autoimmune thyroid disorders and 3% to 7% in primary biliary cirrhosis in prospective studies. Conversely, there is also an increased prevalence of immune based disorders among patients with CD. The pathogenesis of co-existent autoimmune thyroid disease and CD is not known, but these conditions share similar HLA haplotypes and are associated with the gene encoding cytotoxic T-lymphocyte-associated antigen-4. Screening high risk patients for CD, such as those with autoimmune diseases, is a reasonable strategy given the increased prevalence. Treatment of CD with a gluten-free diet should reduce the recognized complications of this disease and provide benefits in both general health and perhaps life expectancy. It also improves glycemic control in patients with type 1 diabetes mellitus and enhances the absorption of medications for associated hypothyroidism and osteoporosis. It

    Interstitial laser photocoagulation (ILP) is a new therapeutic option for the ablation of non-functioning and hyper-functioning benign thyroid nodules. Amelioration of the ablation procedure currently allows treating large nodules. Aim of this study was to evaluate the therapeutic efficacy of ILP, performed according to a modified protocol of ablation, in patients with large functioning and non-functioning thyroid nodules and to identify the best parameters for predicting successful outcome in hyperthyroid patients. Fifty-one patients with non-functioning thyroid nodules (group 1) and 26 patients with hyperfunctioning thyroid nodules (group 2) were enrolled. All patients had a nodular volume ≥40 ml. Patients were addressed to 1-3 cycles of ILP. A cycle consisted of three ILP sessions, each lasting 5-10 minutes repeated at an interval of 1 month. After each cycle of ILP patients underwent thyroid evaluation. A nodule volume reduction, expressed as percentage of the basal volume, significantly occurred in both groups (F = 190.4; P < 0.0001 for group 1 and F = 100.2; P < 0.0001 for group 2). Receiver-operator-characteristic (ROC) curves were constructed for: (i) percentage of volume reduction; (ii) difference in nodule volume; (iii) total amount of energy delivered expressed in Joule. ROC curves identified the percentage of volume reduction as the best parameter predicting a normalized serum TSH (area under the curve 0.962; P < 0.0001). Intraoperative complications consisted in: (i) mild pain occurring in five (6.5%) patients, (ii) vasovagal reaction in two (2.6%) patients, (iii) fever within 24 hours from ILP in five (6.5%) patients. No major complications including persistent pain, laringeal nerve dysfunction, hypoparathyroidism, pseudocystic transformation, and/or neck fascitis were observed. ILP represents a valid alternative to surgery also for large benign thyroid nodules, both in terms of nodule size reduction and cure of

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

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

    Objective: Microwave ablation is a minimally invasive technique that has been used to treat benign and malignant tumors of liver, lung and kidney. Towards thyroid nodules, only a few cases are reported so far. The aim of the study was to investigate the effectiveness and safety of ultrasound-guided percutaneous microwave ablation in the treatment of benign thyroid nodules with a large sample. Materials and methods: A total of 477 benign thyroid nodules in 222 patients underwent microwave ablation in our department from July 2009 to March 2012. Microwave ablation was carried out using microwave antenna (16G) under local anesthesia. Nodule volume, thyroid function and clinical symptoms were evaluated before treatment and at 1, 3, more than 6 months. The study was ethics committee approved and written informed consents were obtained from all patients. Results: All thyroid nodules significantly decreased in size after microwave ablation. A 6-month follow-up was achieved in 254 of 477 nodules, and the mean decrease in the volume of thyroid nodules was from 2.13 ± 4.42 ml to 0.45 ± 0.90 ml, with a mean percent decrease of 0.65 ± 0.65. A volume-reduction ratio greater than 50% was observed in 82.3% (209/254) of index nodules, and 30.7% (78/254) of index nodules disappeared 6-month after the ablation. The treatment was well tolerated and no major complications were observed except pain and transient voice changes. Conclusions: Microwave ablation seems to be a safe and effective technique for the treatment of benign thyroid nodules. Further prospective randomized studies are needed to define the role of the procedure in the treatment of thyroid nodules

    Cases of radiation therapy for benign diseases have diminished in number because of recent alternative methods and knowledge about radiation carcinogenesis. In contrast to this tendency, our cases of benign diseases have recently increased. The facts made us reconsider today's radiation therapy of benign diseases. We reviewed 349 patients who were diagnosed as having benign tumors or non-neoplastic conditions and treated by radiation therapy in the past sixteen years. Analyzed items were the annual transition of treatment number, sorts of diseases, patients' age and sex, and the goal of therapy. Of all radiation therapy patients, benign diseases account for 9.26%. The annual percentages were 0.5%, 6.0%, 11.2% and 13.7% at intervals of five years since 1982. The majority was 246 post-operative irradiation for keloids (71%) and 41 pituitary adenomas (12%). Compared with malignant tumors, benign disease patients were statistically younger and female-dominant. Applications of radiation therapy in keloids and pituitary adenomas had definite goals, but were unclear in other rare diseases. Benign diseases should be treated by radiation therapy as the second or third option, provided the patients have serious symptoms and their diseases do not respond to other modalities. It seems to be widely accepted that favorite cases such as keloids and pituitary adenomas are treated by radiation therapy. But, optimal radiation therapies for other rare benign diseases have not been established. Therefore, the building of databases on radiation therapy on benign diseases should be pursued. Since benign disease patients were young and female-dominant and had many remaining years, their carcinogenicity potential should be considered. (author)

  8. Thyroid Disorders and Chronic Kidney Disease

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

  9. Radioiodine treatment for malignant thyroid disease

    International Nuclear Information System (INIS)

    Berg, Gertrud

    2006-01-01

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

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

    There is no information about the frequency of malignancy specifically in the case of thyroid nodules with highly suspicious sonographic features, but with two fine needle aspiration (FNA) showing benign cytology. This was the objective of the study. Subjects and methods: We report the results of 105 patients with thyroid nodules considered 'highly suspicious' according to the ultrasonographic classification of American Thyroid Association, in whom FNA revealed benign cytology on two occasions (interval of 6 months). Results: Thyroidectomy was performed in 11 cases due to desire of the patient or significant growth of the nodule. In these patients, cytology continued to be benign in 9, was non-diagnostic in 1, and suspicious in 1. Histology revealed papillary carcinoma in only one nodule. In patients in whom a third FNA was obtained for this study (n = 94), cytology continued to be benign in 86, became non-diagnostic in 5, indeterminate in 2, and suspicious in 1. The last 8 patients (with non-benign cytology) were submitted to thyroidectomy and histology revealed malignancy in only one nodule. Conclusion: The rate of malignancy found here for nodules with highly suspicious sonographic features, even after two FNA showing benign cytology, was 2%. We believe that in these cases, the continuation of follow-up consisting of ultrasound at intervals of 2 years may still be adequate. (author)

    The possible association between cigarette smoking and the risk of benign breast disease (BBD) was assessed in a case-control study conducted in Gdansk, Poland, between 1990 and 1994. The study compared 160 women with newly diagnosed BBD admitted to the Gdansk Cancer Outpatients Clinic and 160 controls, women from outpatients clinics at the Medical University of Gdansk. There was no convincing evidence of an association, either positive or negative, between various indicators of smoking habit (smoking status, number of cigarettes smoked per day, duration of smoking) and the risk of BBD. Slightly lower relative risk (RRs) of BBD in ex-smokers of 10 or more cigarettes per day (RR = 0.9; 95% confidence interval, CI: 0.4-2.2), and with duration of smoking >= (RR = 0.1-3.4), were also observed in current smokers (RR = 0.8; 95% CI: 0.4-1.5), and (RR = 0.8; 95% CI: 0.1-3.4), but these findings were not statistically significant.

    Because sodium iodide I 131 was the first radiopharmaceutical available for clinical use, and because thyroid hormonogenesis is dependent on iodide, the earliest tests in nuclear medicine were aimed at the diagnosis of thyroid diseases. Two types of the early thyroid tests required intervention - pharamacologic manipulation of the patient - to express diagnostic information: (1) the suppression test in which thyroid hormone was given, and (2) the stimulation test wherein thyrotropin (TSH) was injected. As happens in the evolution of medical practice, newer procedures replace the old, and both the suppression and stimulation tests of thyroid function now are rarely used; the data sought can usually be obtained by other safer or more accurate procedures. However, a suppression test or a stimulation test may still be of indispensible value in certain patients

    To evaluate the reduction over time of benign thyroid nodules treated using percutaneous laser ablation (PLA) and radiofrequency ablation (RFA) by the same equipe. Ninety patients (age 55.6 ± 14.1 years) underwent ablation for benign thyroid nodule causing compression/aesthetic dissatisfaction from 2011. Fifty-nine (age 55.8 ± 14.1 years) underwent RFA and 31 (age 55.2 ± 14.2 years) PLA, ultrasound guided. Technical success, complications, duration of ablation and treatment, energy deployed, volumetric percentage reduction at 1, 6 and 12 months were derived. A regression model for longitudinal measurements was used with random intercept and random slope. Values are expressed as mean ± standard deviation or N (%). Technical success was always obtained. No major complications occurred. Mean ablation time was 30.1 ± 13.8 vs. 13.9 ± 5.9 min (p < .0001) and mean energy deployment was 5422.3 ± 2484.5 J vs. 34 662.7 ± 15 812.3 J in PLA vs. RFA group. Mean volume reduced from 20.3 ± 16.4 ml to 13.17 ± 10.74 ml (42% ± 17% reduction) at 1st month, 8.7 ± 7.4 ml (60% ± 15% reduction) at 6th month and 7.1 ± 7.7 ml (70%% ± 16% reduction) at 12th month, in PLA group, and from 32.7 ± 19.5 ml to 17.2 ± 12.9 ml (51%±15% reduction) at 1st month, 12.8 ± 9.6 ml (64 ± 14% reduction) at 6th month and 9.9 ± 9.2 ml (74% ± 14% reduction) at 12th month in RFA group. No difference in time course of the relative volume reduction between the two techniques was found. RFA and PLA are similarly feasible, safe and effective in treating benign thyroid nodules when performed by the same equipe. RFA is faster than PLA but require significantly higher energy.

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

    Background and purpose: Sentinel lymph node biopsy has been proven to be successful and accurate in predicting the nodal status in melanoma and breast cancer. Occult lymph node metastases are common in well differentiated thyroid cancer (WDTC). Although the prognostic significance of these occult lymph node metastases remains controversial, identifying these patients may help direct therapy. The purpose of the study was to assess the technical feasibility and the safety of the sentinel lymph node biopsy in uni-nodular thyroid disease. Methods: Patients of previously untreated benign solitary thyroid nodule, diagnosed preoperatively by fine needle aspiration cytology without any palpable cervical lymph node were prospectively studied. The nodule was injected with iso sulfan blue vital dye. Blue stained lymphatics were traced. Then, hemi thyroidectomy was per-formed. Results: A total of 30 patients underwent sentinel lymph node biopsy; lymph tics were observed in 23 patients and sentinel lymph nodes were found in 18. In 5 patients, blue stained lymphatics were traced to the outside of the central compartment but no sentinel lymph node was identified. Sentinel lymph nodes were located in the central compartment in 14 cases, in the lateral compartment in 3 cases and in one patient 2 sentinel lymph nodes were found in both the central and the lateral compartments. Overall detection of sentinel lymph nodes was possible in 60% of cases. There were no intra or postoperative complications. Conclusions: The role of sentinel lymph node biopsy has yet to be determined in the thyroid setting. Certainly the technique can be performed safely, but its accuracy needs further refinement and investigation on larger series of patients before it can be recommended in the routine management of thyroid neoplasia.

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

  1. Interactions between thyroid disorders and kidney disease

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

    The increasing use of positron emission tomography-computed tomography (PET/CT) has led to the frequent detection of incidental thyroid and neck lesions with increased 18F-deoxyglucose (FDG) uptake. Although lesions with increased FDG uptake are commonly assumed to be malignant, benign lesions may also exhibit increased uptake. The purpose of this pictorial essay is to demonstrate that benign thyroid and neck lesions can produce false-positive findings on PET/CT, and to identify various difficulties in interpretation. It is crucial to be aware that differentiating between benign and malignant lesions is difficult in a considerable proportion of cases, when relying only on PET/CT findings. Correlation of PET/CT findings with additional imaging modalities is essential to avoid misdiagnosis.

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

Equally important, the intraindividual variability of the thyroid hormone measurements is much narrower than the interindividual variation (reflecting the reference interval. The best laboratory assessment of thyroid function is a free thyroid hormone estimate combined with TSH. Measurement of antithyroperoxidase and/or TSH receptor antibodies adds to the differential diagnosis of autoimmune and nonautoimmune thyroid diseases.

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

    Full Text Available Objective: To study the value of HIC1 and SIRT1 expression levels in thyroid nodule for assessing benign or malignant nodules. Method: 70 cases of surgically removed thyroid cancer tissue samples were collected as pathology group, 70 cases of corresponding para-carcinoma tissue specimens were collected as control group, immunohistochemistry was used to detect HIC1 and SIRT1 protein expression levels, and fluorescence quantitative PCR was used to detect the mRNA expression levels of HIC1 and SIRT1 as well as OXTR, CDH1, RASSF1A, TIMP3, MMP13, S100A4, CCNG2 and MK. Results: HIC1 expression levels in thyroid carcinoma tissue of pathology group were significantly lower than those of control group while SIRT1 expression levels were significantly higher than those of control group; compared with thyroid cancer tissue with TNM I-II stage, negative ductal infiltration and negative lymph node metastasis, HIC1 expression levels significantly decreased while SIRT1 expression levels significantly increased in thyroid cancer tissue with TNM III-IV stage, positive ductal infiltration and positive lymph node metastasis; in thyroid cancer tissue with positive HIC1 expression, OXTR, CDH1, RASSF1A and TIMP3 expression levels were significantly higher than those in thyroid cancer tissue with negative HIC1 expression; in thyroid cancer tissue with positive SIRT1 expression, MMP13, S100A4, CCNG2 and MK expression levels were significantly higher than those in thyroid cancer tissue with negative SIRT1 expression. Conclusion: HIC1 expression deletion and SIRT1 expression increase in thyroid nodule tissue are associated with the occurrence and development of thyroid carcinoma, and methylation and deacetylation may be epigenetic mechanism of HIC1 and SIRT1 to regulate cell proliferation, invasion and angiogenesis.

  8. Targeting thyroid diseases with TSH receptor analogs.

    2013-12-01

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

    Full Text Available Background Synthesis of thyroid hormones and regulation of their metabolism involve free radicals that may affect redox balance in the body. Thyroid disorders causing variations in the levels of thyroid hormones may alter cellular oxidative stress. The aim of this study was to measure the antioxidant activities and biomarkers of oxidative stress in serum and red blood cells (RBC of patients with benign and malignant thyroid disorders and to investigate if changes in the antioxidant activities in these patients were linked to alterations in genes encoding the antioxidant enzymes. Methods Forty-one patients with thyroid disorders from University of Malaya Medical Centre were recruited. They were categorised into four groups: multinodular goitre (MNG (n = 18, follicular thyroid adenoma (FTA (n = 7, papillary thyroid cancer (PTC (n = 10, and follicular thyroid cancer (FTC (n = 6. Serum and RBC of patients were analysed for antioxidant activities, antioxidant enzymes, and biomarkers of oxidative stress. Alterations in genes encoding the antioxidant enzymes were analysed using whole exome sequencing and PCR–DNA sequencing. Results Patients with thyroid disorders had significantly higher serum superoxide dismutase (SOD and catalase (CAT activities compared to control, but had lower activities in RBC. There were no significant changes in serum glutathione peroxidase (GPx activity. Meanwhile, GPx activity in RBC was reduced in PTC and FTC, compared to control and the respective benign groups. Antioxidant activities in serum were decreased in the thyroid disorder groups when compared to the control group. The levels of malondialdehyde (MDA were elevated in the serum of FTA group when compared to controls, while in the RBC, only the MNG and PTC groups showed higher MDA equivalents than control. Serum reactive oxygen species (ROS levels in PTC group of both serum and RBC were significantly higher than control group. Whole exome sequencing has resulted in

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

    Autoimmune thyroid disease (AITD) is often observed together with other autoimmune diseases. The coexistence of two or more autoimmune diseases in the same patient is referred to as polyautoimmunity, and AITD is the autoimmune disease most frequently involved. The occurrence of polyautoimmunity has...... led to the hypothesis that the affected patients suffer from a generalized dysregulation of their immune system. The present review summarizes recent discoveries unravelling the immunological mechanisms involved in autoimmunity, ranging from natural autoimmunity to disease-specific autoimmunity...

    Ephrin receptors (Ephs) are frequently overexpressed in a wide variety of human malignant tumors, being associated with tumor growth, invasion, angiogenesis and metastasis. The present study aimed to evaluate the clinical significance of EphB4 and EphB6 protein expression in human malignant and benign thyroid lesions. EphB4 and EphB6 protein expression was assessed immunohistochemically on paraffin-embedded thyroid tissues obtained from 127 patients with benign (n = 71) and malignant (n = 56) thyroid lesions. Enhanced EphB4 and EphB6 expression was more frequently observed in malignant compared to benign thyroid lesions (p = 0.0508 and p = 0.0006, respectively). EphB4 and EphB6 expression also provided a distinct discrimination between papillary carcinoma and hyperplastic nodules (p = 0.0302 and p = 0.0013, respectively). In malignant thyroid lesions, enhanced EphB4 expression was significantly associated with larger tumor size (p = 0.0366). Enhanced EphB6 expression was significantly associated with larger tumor size (p = 0.0366), the presence of lymph node metastases (p = 0.0023), the presence of capsular (p = 0.0038), lymphatic (p = 0.0053) and vascular invasion (p = 0.0018) and increased risk of recurrence rate (p = 0.0038). The present study supported evidence that EphB4 and mainly EphB6 may participate in the malignant thyroid transformation, reinforcing their utility as useful biomarkers and possible therapeutic targets in this type of neoplasia.

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

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

    Depression in an elderly man with primary recurrent unipolar depression responded to radioactive iodine treatment of a thyrotoxic nodule, without the addition of psychotropic medications. Two months later, manic symptoms developed concomitant with the termination of the hyperthyroid state secondary to the radioactive iodine treatment. Clinical implications of these findings in relation to the possible mechanism of action of thyroid hormones on affective cycling are discussed

    Retrospective review was carried out of 124 patients with nodular disease of the thyroid gland and a history of radiation exposure who had undergone needle aspiration biopsy. Latency period from time of radiation varied from 2 to 50 years; but in 92 patients it exceeded 2 decades. Our patient group included those with occupational exposure and a past history of radiation for cancer. Incidence of cancer in the entire group was 49% but, for solitary lesions, this was increased to 56%, while only a 30% incidence of cancer was found in cases of multinodular goiters. Accuracy of needle aspiration biopsy overall was 74%: for the group with cancer--90%, for the group with adenomas--65%, and for the group with ''benign'' tumors--83%. Further assessment of needle technique indicated a sensitivity of 70%, specificity of 90%, positive predictive value of 90%, and negative predictive value of 83% to 65%. The accuracy could be increased to 84% if all adenomas were considered as possible malignancies. Eighteen percent of our patients had second tumors in the head and neck or breast area. Near-total thyroidectomy was considered to be the preferred procedure without accidental nerve injury and was done in one case of hypoparathyroidism after excision of an extensive tracheal invasive cancer. No evidence of death, recurrence, or metastasis as a result of thyroid cancer has been noted. While needle biopsy is indispensable to intelligent management, the history of radiation to the head and neck area must be preeminent in the selection of patients for surgical treatment. Conservative management appears to be reasonable in those patients with ''benign'' cytology, a less than 1 cm nodule, multinodularity, a functioning thyroid scan result, but persistence in the face of a lack of response to conservative management does not appear to be warranted.

Thyroid autoimmune activity is decreasing in pregnancy. Measurement of serum TSH is the first-line screening variable...... for thyroid dysfunction also in pregnancy. However, using serum TSH for control of treatment of maternal thyroid autoimmunity infers a risk for compromised foetal development. Peripheral thyroid hormone values are highly different among laboratories, and there is a need for laboratory-specific gestational age......-related reference ranges. Equally important, the intraindividual variability of the thyroid hormone measurements is much narrower than the interindividual variation (reflecting the reference interval).

    Hashimoto's thyroiditis (HT) is a common disease, and is the most prevalent cause of hypothyroidism. Symptoms and diseases associated with HT are considered to be caused by hypothyroidism. We hypothesized that higher antithyroperoxidase (anti-TPO) antibody levels would be associated with an increased symptom load and a decreased quality of life in a female euthyroid patient collective. In a prospective cohort study 426 consecutive euthyroid female patients undergoing thyroid surgery for benign thyroid disease were included. Main outcome measures were preoperative anti-TPO levels, a symptom questionnaire and the SF-36 questionnaire, and lymphocytic infiltration of the thyroid tissue as evaluated by histology. Histology revealed HT in 28/426 (6.6%) subjects. To maximize the sum of the predictive values, a cut-off point for anti-TPO of 121.0 IU/mL was calculated (sensitivity 93.3% [95% confidence interval: 77.9%-99.0%]; specificity 94.7% [95% confidence interval: 92.0%-96.7%]) to predict the presence of histological signs of HT. The mean number of reported symptoms was significantly higher in patients with anti-TPO levels >121.0 IU/mL than in the other group (6.7 ± 2.5 vs. 4.1 ± 2.8; p thyroid-stimulating hormone levels (1.7 ± 1.3 vs. 1.5 ± 1.4 μU/mL, respectively; p = 0.155). Chronic fatigue, dry hair, chronic irritability, chronic nervousness, a history of breast cancer and early miscarriage, and lower quality-of-life levels were significantly associated with anti-TPO levels exceeding the cut-off point (p symptom load. Hypothyroidism is only a contributing factor to the development of associated conditions.

    This note compares mortality figures for patients treated with low dose ionizing radiation for benign conditions between the 1920's and 1950's with figures available from the Japanese A-bomb survivors. X radiation for ringworm, ankylosing spondylitis and post-partum mastitis are considered. Figures for leukemia are roughly comparable between radiotherapy groups and A-bomb survivors. Figures for the increased relative risk of breast cancer in spondylitis patients were in marked contrast to bomb survivors who received comparable doses, but compatible with the increase among women given x-rays for acute post-partum mastitis in the 1940's and 1950's. This study also suggests the possibility of different time patterns of risk between different cancers. (U.K.).

    A discussion in literature about a standardized decision support tool for the management of thyroid nodules remains. The purpose of this study was to create a statistical prediction model for thyroid nodules management. Two hundred and four benign and 57 malignant thyroid nodules were selected for a retrospective study. The variables age, gender and ultrasonographic features were examined using univariate and multivariate models. A statistical formula was used to calculate the risk of cancer of each case. In multivariate analysis, irregular shape, absence of halo, lower mean age, homogeneous echotexture, microcalcifications and solid content were associated with cancer. After applying the formula, 20 cases (7.6%) with a calculated risk for malignancy ≤3.0% were found, all of them benign. Setting the calculated risk in ≥80%, 21 (8.0%) cases were selected, and in 85.7% of them cancer was confirmed in histopathology. Internal accuracy of the prediction formula was 92.5%. The prediction formula reached high accuracy and may be an alternative to other decision support tools for thyroid nodule management.

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

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

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

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

    Full text: The thyroid ability to store and concentrate iodine is of importance for radioiodine therapy in thyroid cancer. It is known that a normal thyroid contains 2-20 mg iodine while the information regarding malignant thyroid tissue is scarce. The purpose of this study was to investigate the iodine concentration in benign compared to malignant tissue. Methods: Thyroid tissue samples from healthy patients and from patients with papillary cancer were collected and frozen in connection with surgery. For the thyroid cancer patients, tissue was taken from both benign and malignant tissue. The iodine concentration was analysed with an XRF system consisting of a 241-Am source and an HPGe detector. When irradiating iodine containing tissue, characteristic X-rays are emitted. That radiation is detected with the strength of the detected signal being proportional to the amount of iodine in the sample. SIMS was used on glutaraldehyde fixed tissue as a histological tool for quantification and localization of iodine by sputtering and analysis of secondary ions. Results: The iodine concentration in benign tissue is considerably higher than in malignant samples. XRF measurements showed a medium iodine concentration in healthy thyroid tissue of 0.5 mg/mL. For the cancer patients, the iodine concentration was 0.3 mg/mL in benign tissue while no iodine could be detected in the malignant samples. These findings were consistent with the results from the SIMS investigation that gave a 100 times lower iodine concentration in malignant than in benign tissue. SIMS also showed that the iodine in benign tissue was predominantly located in the follicle lumen, while in the cancer cells low iodine concentration was found intra cellular as well as in the lumen. Conclusion: Iodine concentration in tissue from papillary cancer can be 100 times lower than in normal thyroid tissue. This is in accordance with the empirical knowledge that thyroid cancer should need about 100 times higher activity

    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.

    Thyroid hormones (TH) play a key role in energy homeostasis throughout life. Thyroid hormone production and secretion by the thyroid gland is regulated via the hypothalamus-pituitary-thyroid (HPT)-axis. Thyroid hormone has to be transported into the cell, where it can bind to the thyroid hormone

    Radioiodine is currently used routinely in the treatment of hyperthyroidism including Graves' disease (GD), toxic multinodular goitre (TMNG) and toxic solitary nodule (TSN) but no consensus exists on the most appropriate way to prescribe iodine--fixed dose or calculated doses based on the gland size or turnover of (131)I. We carried out the first nationwide French survey assessing the current practices in radioiodine treatment of hyperthyroidism. A questionnaire was sent to French nuclear medicine hospital units and cancer treatment centres (n=69) about their practices in 2012. Euthyroidism was considered the successful outcome for 33% of respondents, whereas hypothyroidism was the aim in 26% of cases. Fixed activities were the commonest therapeutic approach (60.0% of GD prescribed doses and 72.5% for TMNG and TSN), followed by calculated activities from Marinelli's formula (based on a single uptake value and thyroid volume). The fixed administered dose was chosen from between 1 to 3 levels of standard doses, depending on the patient characteristics. Factors influencing this choice were disease, with a median of 370 MBq for GD and 555 MBq for TSN and TMNG, thyroid volume (59%) and uptake (52%) with (131)I or (99m)Tc. Even physicians using fixed doses performed pretherapeutic thyroid scan (98%). This study shows that practices concerning the prescription of (131)I therapeutic doses are heterogeneous. But the current trend in France, as in Europe, is the administration of fixed doses. The study provides the baseline data for exploring the evolution of French clinical practices. Copyright © 2014.

  20. New Genetic Insights from Autoimmune Thyroid Disease

    Directory of Open Access Journals (Sweden)

    Terry F. Davies

    2012-01-01

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

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

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren`s disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

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

    Thyroid hormones play an important role in the regulation of physiologic processes. Thyroid disease can lead to imbalance in the homeostasis of the body and affect the healing capacity of tissues. However, limited data are available regarding the relationship between thyroid hormone imbalance (thyroid disease) and periodontal health. This review is carried out to summarize the relationship between thyroid disease and periodontal status. PUBMED and MEDLINE searches of both human and animal studies were performed to investigate the relationship between thyroid disease, periodontal status, and dental implants. Results suggest that thyroid diseases may affect the status of periodontal diseases, especially in hypothyroid conditions. The duration from disease onset to treatment of thyroid disorders may be critical, since uncontrolled thyroid disease may result in destruction of the periodontium. Further controlled studies are needed to explore the relationship between thyroid hormone imbalance and periodontal status. Periodontal therapies, including dental implant placement, appear to be safe with no increase in treatment failure, so long as the status of the thyroid gland is controlled.

    Benign multicystic peritoneal mesothelioma is an uncommon lesion arising from the peritoneal mesothelium. It is asymptomatic or presents with unspecific symptoms. Imaging techniques may reveal it, however the final diagnosis can only be made by histopathology. Surgery is the only effective treatment considering its high recurrence rate. We report a 19 years old male with Crohn’s disease. Due to persistent abdominal pain, an abdominal magnetic resonance imaging was performed, showing a complex cystic mass in the lower abdomen. The patient underwent surgery and the lesion was completely resected. The pathological study reported a benign multicystic peritoneal mesothelioma.

    Autoimmune thyroid diseases (AITD) are common, affecting 2-5% of the general population. Individuals with positive thyroid peroxidase antibodies (TPOAbs) have an increased risk of autoimmune hypothyroidism (Hashimoto's thyroiditis), as well as autoimmune hyperthyroidism (Graves' disease.......12-1.39, P = 6.2×10(-5)). The MAGI3 variant was also associated with an increased risk of hypothyroidism (OR: 1.57, 95% CI 1.18-2.10, P = 1.9×10(-3)). This first GWAS meta-analysis for TPOAbs identified five newly associated loci, three of which were also associated with clinical thyroid disease....... With these markers we identified a large subgroup in the general population with a substantially increased risk of TPOAbs. The results provide insight into why individuals with thyroid autoimmunity do or do not eventually develop thyroid disease, and these markers may therefore predict which TPOAb...

  7. Clinical evaluation of echography in diagnosis of thyroid disease

    1983-01-01

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

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

    Thyroid gland diseases vary according to the environment. In sub-Saharan Africa, they are also influenced by population isolation and the absence of food self-sufficiency, both factors affecting the onset and persistence of iodine-deficiency goiters. More cosmopolitan diseases are now added to these thyroid disorders. Women are mainly affected (94.2%), most often with euthyroid goiters (54.7%), followed by Graves disease (13.1%), hypothyroidism (8.8%), thyroiditis (6.6%), toxic multinodular goiters (6.6 %) and unclassified goiters (10%) [Gabon]. The paucity of laboratories specializing in endocrinology and of nuclear medicine facilities, the delay in diagnosis that results in compressive or recurrent goiters, and endemic goiters are all typical in Africa. In children and adolescents, death rates increase with congenital or acquired thyroiditis as with delayed physical or mental development. In this environment, thyroiditis can also be pregnancy-related. Very recent surveys show a prevalence of endemic goiters of 28.6% in the community of Sekota, Ethiopia, 64-70% in Sahel-Sudan (population aged 10-20 years), 20-29% in KwaZulu-Natal (school children), 14.3-30.2% in Namibia (school children), 0.21% (congenital hypothyroidism or cretinism) in Plateau State, Nigeria, 55.2% at Zitenga, Burkina Faso (210 persons 0-45 years), and 10% in Hararé and Wedza, Zimbabwe (newborn TSH >10.1 microIU/mL). The prevalence of goiters is 43.6% in children emigrating from Ethiopia to Israel. Millet from semi-arid zones contains apigenin at a concentration of 150 mg/kg and luteolin at 350 mg/kg, both of which can interfere with thyroid function. The harmful effects of cassava (also known as manioc) are better known: milling cassava reduces its goitrogenic potential. In addition to iodine deficiency, selenium deficiency, and the effect of the thiocyanates in cassava, ion concentrations in soil and drinking water appear to play a role. The proportion of thyroid surgery indicated for

    The receptor-binding cancer antigen expressed on SiSo cells (RCAS1) is a human tumor-associated antigen that contributes to tumor progression by enabling cancer cells to evade immune surveillance. The present study aimed to evaluate the clinical significance of RCAS1 expression in human benign and malignant thyroid lesions. RCAS1 protein expression was assessed immunohistochemically on paraffin-embedded thyroid tissues from 121 patients with benign and malignant lesions and was associated with type of thyroid histopathology and tumor stage parameters such as tumor size, lymph node metastases, capsular, lymphatic and vascular invasion. RCAS1 positivity, overexpression and staining intensity provided a distinct discrimination between benign and malignant thyroid cases (p=0.0006, p=0.0001 and p=0.0001, respectively), as well as between hyperplastic nodule and papillary carcinoma cases (p=0.0229, p=0.0001 and p=0.0001, respectively). RCAS1 positivity, overexpression and staining intensity also provided distinct discrimination between cases with Hashimoto thyroiditis and those with hyperplastic nodule (p=0.0221, p=0.0001 and p=0.0019, respectively). In the subgroup of malignant thyroid lesions, RCAS1 overexpression was significantly associated with large tumor size (p=0.0246), the presence of lymph node metastases (p=0.0351) and capsular invasion (p=0.0397). RCAS1 protein may participate in thyroid neoplastic transformation and could be considered as a useful biomarker to improve diagnostic scrutiny.

    In summary, the lecture presents today's state of nuclear medical diganostics in benign bone disease, the radiopharmaceuticals, and the methods used. Besides the [sup 99]m-Tc-labeled diphosphonates a couple of additional radioactive labeled substances play an important part in bone scintigraphic imaging especially in scanning inflammatory bone disease and the bone marrow. There are several substances available to label leucocytes and human immunoglobulins. Concerning the methods the performance of the 3-phase bone scanning and the application of SPECT becomes increasingly important. In detail discussed are among other methods the inflammation-scanning in osteomyelitis, the scintigraphic imaging in benign bone tumors and tumor like lesions, in circulation disorders of the bone with necroses and hyperperfusion (reflex sympathetic dystrophy, transient hip osteoporosis), and in bone lesions following trauma or stress, for example also in battered child syndrome. The indication to the different imaging procedures as X-ray, computed tomography, nuclear magnetic resonance, and scintigraphic imaging are discussed, whereby the scintiscanning urges its place, mainly due to good specifity, in documenting the different functional states of the bone such as inflammation, perfusion, necrosis, tumor and/or bone marrow infiltration.

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

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

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

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

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

    Celiac disease (CD) may be associated with other immunologic disorders in adults and children. Previous studies linking CD and autoimmune thyroid disease in children have included very few patients with limited biochemical and immunologic screening tests. The aim of this multicenter study was to establish the prevalence of autoimmune thyroid involvement in a large series of pediatric patients with CD. Five hundred seventy-three consecutive pediatric patients were enrolled from clinics in Torino, Bologna, Foggia, Rome (two clinics), Naples, and Bari. Three hundred forty-three patients with CD were studied, 230 girls and 113 boys (median age, 8.5 years). Two hundred fifty-six of the patients with CD (median age, 9 years) had been following a gluten-free diet for 3 months to 16 years; 87 patients were untreated (median age, 6.2 years). The diagnosis of CD was made using the European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) criteria. A control group of 230 subjects (median age, 8.3 years) was enrolled. Serum free triiodothyronine, free thyroxine, and thyroid-stimulating hormone (TSH), antithyroperoxidase, antithyroglobulin, anti-TSH receptor antibodies, and thyroid echographic pattern were considered. Autoimmune thyroid disease was found in 90 of 343 (26.2%) patients with CD (62 on a gluten-free diet) and in 20 (10%) of the control subjects (P = 0.001). Fifty-four (15.7%) patients with CD and autoimmune markers had normal thyroid function (euthyroidism) as did 12 (6.0%) of the control subjects; hypothyroidism was observed in 28 (8.1%) patients with CD and in 7 (3.5%) of the control subjects. Hyperthyroidism was diagnosed in four patients with CD and in none of the control subjects with autoimmune markers. An abnormal echographic pattern was seen in 37 patients with CD (16.8%) and only in 1 (1.6%) of the control subjects (P = 0.002).

    Spontaneous orbital fracture is a rare entity. A 32-year-old man presented with thyroid eye disease and was found to have an orbital floor fracture on routine preoperative imaging without any antecedent relevant symptom or sign. To the best of the authors' knowledge, this is the first report of an asymptomatic orbital fracture in a patient with thyroid eye disease.

    Histone deacetylases (HDACs) have been associated with human malignant tumor development and progression, and HDAC inhibitors are currently being explored as anticancer agents in clinical trials. The present study aimed to evaluate the clinical significance of HDAC-1, HDAC-2, HDAC-4, and HDAC-6 proteins' expression in human malignant and benign thyroid lesions. HDAC-1, HDAC-2, HDAC-4, and HDAC-6 proteins' expression was assessed immunohistochemically on paraffin-embedded thyroid tissues obtained from 74 patients with benign and malignant thyroid lesions. Enhanced HDAC-2 and HDAC-6 expression was significantly more frequently observed in malignant, compared to benign, thyroid lesions (p = 0.0042 and p = 0.0069, respectively). Enhanced HDAC-2, HDAC-4, and HDAC-6 expression was significantly more frequently observed in cases with papillary carcinoma compared to hyperplastic nodules (p = 0.0065, p = 0.0394, and p = 0.0061, respectively). In malignant thyroid lesions, HDAC-1, HDAC-4, and HDAC-6 expression was significantly associated with tumor size (p = 0.0169, p = 0.0056, and p = 0.0234, respectively); HDAC-2 expression with lymphatic and vascular invasion (p = 0.0299 and p = 0.0391, respectively); and HDAC-4 expression with capsular invasion (p = 0.0464). The cellular pattern of HDAC-1 and HDAC-2 distribution (nuclear vs. nuclear and cytoplasmic) presented a distinct discrimination between malignant and benign thyroid lesions (p = 0.0030 and p = 0.0028, respectively) as well as between papillary carcinoma and hyperplastic nodules (p = 0.0036 and p = 0.0028, respectively). HDAC-1, HDAC-2, HDAC-4, and HDAC-6 may be associated with the malignant thyroid transformation and could be considered as useful biomarkers and possible therapeutic targets in this neoplasia.

  12. Radiation for not-so-benign coronary artery disease

    The role of radiation therapy in the treatment of malignant disease has long been accepted. More limited application of radiation in the treatment of benign conditions has been proven but generally not pursued. On the centennial anniversary of radiation therapy, a promising, but as yet unproved, application of radiation for treatment of benign vascular disease has become an exciting field of research, speculation, and controversy. This panel presentation will discuss the rationales and dilemmas of applying radiation in the prevention of arterial restenosis after therapeutic intervention. Coronary artery bypass grafting and more recently coronary angioplasty have become accepted, effective therapies to reverse significant coronary stenosis, and thereby benefit the majority of patients with coronary artery disease. However, a large proportion of patients will suffer restenosis in spite of optimal conventional therapy. The search for a means to prevent such restenosis has been partially successful by therapies, and even engineering intravascular devices. In spite of these efforts, a significant number of patients will fail today's conventional therapy and suffer arterial restenosis. Fibroblast myointimal proliferation is felt to be a major element in this restenosis process. Clinical experience shows that radiation inhibits other similar benign fibroblast proliferative processes such as keloid scar formation and heterotopic ossification. Radiation is now being considered as a means to inhibit myointimal fibroblast proliferation and hopefully prevent attendant arterial restenosis as well. This has catalyzed various animal model investigations that have shown significant arteries. Promising results in the animal model and in very early human institutional trials. These trials are designed to determine if radiation is truly effective and can be safely delivered to prevent restenosis in diseased human arteries. This panel discussion will provide a firm basic science and

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

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

    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

    Conventional screening for hypothyroidism is controversial. Although hypothyroidism is underdiagnosed, many organizations do not recommend screening, citing low disease prevalence in unselected populations. We studied attendees at a thyroid health fair, hypothesizing that certain patient characteristics would enhance the yield of testing. We carried out an observational study of participants at a Michigan health fair that focused on thyroid disease. We collected patient-reported symptoms and demographics by questionnaire, and correlated these with the TSH values obtained through the health fair. 794 of 858 health fair attendees participated. Most were women, and over 40% reported a family history of thyroid disease. We identified 97 (12.2%) participants with previously unknown thyroid dysfunction. No symptom or combination of symptoms discriminated between hypothyroid and euthyroid individuals. Hypothyroid and euthyroid participants in the health fair reported each symptom with a similar prevalence (p > 0.01), a prevalence which was very high. In fact, when compared with a previously published case-control study that reported symptoms, the euthyroid health fair participants reported a higher symptom prevalence (range 3.9% to 66.3%, mean 31.5%), than the euthyroid individuals from the case-control study (range 2% to 54%, mean 17.4%). A high proportion of previously undiagnosed thyroid disease was identified at this health fair. We initially hypothesized symptoms would distinguish between thyroid function states. However, this was not the case in this health fair screening population. The prevalence of reported symptoms was similar and high in both euthyroid and hypothyroid participants. Because attendees were self-selected, it is possible that this health fair that focused on thyroid disease attracted participants specifically concerned about thyroid health. Despite the lack of symptom discrimination, the much higher prevalence of hypothyroidism in this study

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

    The increasing prevalence of goiter and thyroid nodules in older patients is accompanied by an increasing frequency of treatment and cost. Cost-effectiveness is given for programs of prophylaxis (primary prevention, e.g. alimentary iodine supplementation), for programs of screening (secondary prevention. e.g. TSH-screening), and for therapeutic strategies to avoid complications of thyroid dysfunction (atrial fibrillation, myocardial infarction, death for cardiac reasons) and to minimize iatrogenic complications (tertiary prevention). Examples of tertiary prevention are radioiodine-therapy of Graves' disease in patients who have an increased risk of relapse after antithyroid drugs (ATD), radioiodine therapy of ouvert or subclinical hyperthyroidism, and radioiodine therapy of large goiters in older patients or in patients suffering from a relevant co-morbidity. A cost-effectiveness-analysis for different therapeutic strategies of Graves' disease has been published using a lifelong time-horizon. The ablative radioiodine dose-regime is cost-effective as a first line therapy if the risk of relapse after ATD exceeds 60%. Cost-minimization-analysis, comparing resection of goiter and radioiodine, has shown lower cost of radioiodine therapy for toxic multinodular goiter up to 100 ml and for Graves' disease up to 60 ml goiter volume. Medical aspects (volume of goiter, uptake of nodules, regressive goiter, suspicion on malignancy, patients' age, co-morbidity, patients' decision) remain decisive for the choice of treatment.

    Full Text Available Objective The incidental thyroid lesion is a common finding during general imaging studies. Their management has been the subject of numerous studies and recommendations. Parathyroid disease workup necessitates imaging investigation of the adjacent thyroid gland and therefore provides a unique window to the perioperative management of thyroid incidentaloma. The specific prevalence of incidental thyroid lesions in the context of parathyroid disease is unknown. We seek to investigate its prevalence during parathyroid workup and surgery and to ascertain if there was a change in management of these patients. Study Design Five-year retrospective database review. Setting Tertiary care medical center. Subjects and Methods The source and indication for referral, preoperative investigation findings, and management of the incidental thyroid lesions were examined. The actual procedure performed and final pathology results were assessed. Results A total of 98 patients and 106 operations, including revision surgeries, were identified. There were 21 incidental thyroid lesions (21.4% detected, whereby 15 patients underwent fine-needle aspirations and 12 subsequently had diagnostic hemithyroidectomies. This decision was made preoperatively in 5 patients and intraoperatively in 7 patients at the time of parathyroid surgery. Along with other pathologies, there were 7 patients with micropapillary thyroid carcinoma identified. Conclusions In our series, the prevalence of incidental thyroid lesion and thyroid malignancy is comparable to the general population. The management of the initial parathyroid disease in our patients was altered by the imaging and cytological findings of these thyroid lesions. This has implications on perioperative counseling of the thyroid and parathyroid disease.

    DNA repair is a major defense mechanism, which contributes to the maintenance of genetic sequence, and minimizes cell death, mutation rates, replication errors, DNA damage persistence and genomic instability. Alterations in the expression levels of proteins participating in DNA repair mechanisms have been associated with several aspects of cancer biology. The present study aimed to evaluate the clinical significance of DNA repair proteins MSH2, MLH1 and MGMT in benign and malignant thyroid lesions. MSH2, MLH1 and MGMT protein expression was assessed immunohistochemically on paraffin-embedded thyroid tissues from 90 patients with benign and malignant lesions. The expression levels of MLH1 was significantly upregulated in cases with malignant compared to those with benign thyroid lesions (p = 0.038). The expression levels of MGMT was significantly downregulated in malignant compared to benign thyroid lesions (p = 0.001). Similar associations for both MLH1 and MGMT between cases with papillary carcinoma and hyperplastic nodules were also noted (p = 0.014 and p = 0.026, respectively). In the subgroup of malignant thyroid lesions, MSH2 downregulation was significantly associated with larger tumor size (p = 0.031), while MLH1 upregulation was significantly associated with the presence of lymphatic and vascular invasion (p = 0.006 and p = 0.002, respectively). Alterations in the mismatch repair proteins MSH2 and MLH1 and the direct repair protein MGMT may result from tumor development and/or progression. Further studies are recommended to draw definite conclusions on the clinical significance of DNA repair proteins in thyroid neoplasia.

    In summary, the lecture presents today's state of nuclear medical diganostics in benign bone disease, the radiopharmaceuticals, and the methods used. Besides the 99 m-Tc-labeled diphosphonates a couple of additional radioactive labeled substances play an important part in bone scintigraphic imaging especially in scanning inflammatory bone disease and the bone marrow. There are several substances available to label leucocytes and human immunoglobulins. Concerning the methods the performance of the 3-phase bone scanning and the application of SPECT becomes increasingly important. In detail discussed are among other methods the inflammation-scanning in osteomyelitis, the scintigraphic imaging in benign bone tumors and tumor like lesions, in circulation disorders of the bone with necroses and hyperperfusion (reflex sympathetic dystrophy, transient hip osteoporosis), and in bone lesions following trauma or stress, for example also in battered child syndrome. The indication to the different imaging procedures as X-ray, computed tomography, nuclear magnetic resonance, and scintigraphic imaging are discussed, whereby the scintiscanning urges its place, mainly due to good specifity, in documenting the different functional states of the bone such as inflammation, perfusion, necrosis, tumor and/or bone marrow infiltration.

    Patients with celiac disease (CD) can develop a gluten related autoimmune disorder that affects not only the small intestine but other tissues as well. An increased prevalence of autoimmune diseases has been reported, particularly autoimmune thyroiditis. The aim of this study was to characterize thyroid disorders in patients with CD. Fifty-two patients with CD (43 female, 9 male; mean age, 41.1 years) were studied. Nine were on a gluten-free diet (GFD). They were divided into four groups: Group 1, without thyroid involvement (n=30); Groups 2A-C, with thyroid involvement (n=22); Group 2A, subclinical hypothyroidism (n=11); Group 2B, clinical hypothyroidism (n=10); and Group 2C, other thyroid disorders (n=1). CD was confirmed by serologic and histologic criteria. Thyroid involvement was detected by measurement of thyroid stimulating hormone (TSH) and anti-thyroperoxidase antibodies (anti-TPO). Increased levels of TSH and/or anti-TPO levels were detected in Groups 2A (21.1%) and 2B (19.2%). The patients of Group 2B presented clinical symptoms of hypothyroidism before the diagnosis of CD, and 5 of these patients were receiving levothyroxine. One woman (Group 2C; 1.92%) had a medullary carcinoma. There was statistical significance between the age when thyroid disease was diagnosed (current age) and the age of CD diagnosis between Groups 1 and 2B. Patients with thyroid involvement presented associated diseases such as diabetes mellitus (2), Down's syndrome (2), ulcerative colitis (1), and dermatitis herpetiformis (2). Our findings demonstrated an increased prevalence of thyroid disorders (hypothyroidism, 19.2%; and subclinical hypothyroidism, 21.2%), and other associated diseases in celiac patients, even on a GFD, increasing with the age of the patients. Screening for associated diseases is recommended for patients with CD, independent of age at diagnosis or treatment duration.

    To evaluate the interobserver variability and performance in the interpretation of ultrasonographic (US) findings of thyroid nodules. 72 malignant nodules and 61 benign nodules were enrolled as part of this study. Five faculty radiologists and four residents independently performed a retrospective analysis of the US images. The observers received one training session after the first interpretation and then performed a secondary interpretation. Agreement was analyzed by Cohen's kappa statistic. Degree of performance was analyzed using receiver operating characteristic (ROC) curves. Agreement between the faculties was fair-to-good for all criteria; however, between residents, agreement was poor-to-fair. The area under the ROC curves was 0.72, 0.62, and 0.60 for the faculties, senior residents, and junior residents, respectively. There was a significant difference in performance between the faculties and the residents (p < 0.05). There was a significant increase in the agreement for some criteria in the faculties and the senior residents after the training session, but no significant increase in the junior residents. Independent reporting of thyroid US performed by residents is undesirable. A continuous and specialized resident training is essential to enhance the degree of agreement and performance

    The authors investigated the incidence of antithyroglobulin antibodies and antibodies and antimicrosomal antibodies measured by tanned red cell hemagglutination method in subjects suffering from various thyroid disorders. 1) In 15 normal patients, neither suffering from any thyroid diseases nor from any other autoimmune disorders, the antithyroglobulin antibodies were all negative, but the antimicrosomal antibody was positive only in one patient (6.7%). 2) The antithyroglobulin antibodies were positive in 31.5% (34 patients) of 108 patients with various thyroid diseases, and the antimicrosomal antibodies were positive in 37.0% (40 patients). 3) of the 25 patients with Graves' diseases, 7 patients (28.0%) showed positive for the antithyroglobulin antibodies, and 9 (36.0%) for the antimicrosomal antibodies. There was no definite differences in clinical and thyroid functions between the groups with positive and negative results. 4) Both antibodies were positive in 16 (88.9%) and 17 (94.4%) patients respectively among 18 patients with Hashimoto's thyroiditis, all of them were diagnosed histologically. 5) Three out of 33 patients with thyroid adenoma showed positive antibodies, and 3 of 16 patients with thyroid carcinoma revealed positive antibodies. 6) TRCH antibodies demonstrated negative results in 2 patients with subacute thyroiditis, but positive in one patient with idiopathic primary myxedema. 7) The number of patients with high titers(>l:802) was 16 for antithyroglobulin antibody, and 62.5% (10 patients) of which was Hashimoto's thyroiditis. Thirteen (65.0) of 20 patients with high titers (>l:802) for antimicrosomal antibody was Hashimoto's thyroiditis. TRCH test is a simple, sensitive method, and has high reliability and reproducibility. The incidences and titers of antithyroglobulin antibody and antimicrosomal antibody are especially high in Hashimoto's thyroiditis.

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

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

    As a consequence of increasing application of ultrasound technology, the detection of asymptomatic thyroid nodules has generally increased. In fact, ultrasound epidemiological studies report that two third of subjects have at least a thyroid nodule, instead of 4-7% detected by clinicians. These evidences suggest the need of a rational approach to the thyroid nodule ''epidemia''. The question of whether clinically unapparent thyroid lesions should be assessed by cytology is still unresolved and, moreover, the clinical significance of nonpalpable (diameter <10 mm) thyroid carcinoma is still a matter of discussion. Aim of this work is to delineate a rational approach to thyroid nodules, taking in account literature data, the most recent guidelines and our clinical experience.

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

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

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

    We aimed to evaluate the efficacy and safety of vigorous saline injection for viscous cystic thyroid nodules. Eighteen patients who underwent ultrasound-guided aspiration for viscous cystic thyroid nodules using a saline injection were included in our study. After failing to aspirate the cyst by the usual method, we vigorously injected saline into the cyst in multiple directions to break up and liquefy the viscous cystic contents to enable aspiration. The initial and the residual volume of the nodule were calculated, and the volume reduction rate and the time taken to perform the aspiration were recorded. The mean volume of the cystic nodules before aspiration was 11.0 mL (range, 1.2 to 26.0 mL), while the postaspiration volume was 4.2 mL (range, 0.2 to 14.5 mL). The mean aspirated volume was 63.7% of the initial volume. The mean procedure time was 12.4 minutes (range, 5 to 26 minutes). There were no significant complications related to the procedure. A vigorous saline injection followed by aspiration can be a useful method to aspirate viscous cystic thyroid nodules as a prestep for further intervention or simple management.

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

    Dendritic cells form a morphologically distinct class of cells characterized by shape, reniform nucleus, absent to weak acid-phosphatase activity and strong Class II MHC determinant positivity. Functionally they are the most efficient cells in antigen presentation to T-lymphocytes which indicates their role in the initiation of an immune response. Using immunehistochemical techniques we studied the presence of dendritic cells in normal Wistar rat and human thyroids, in thyroids of BBW rats developing thyroid autoimmunity and in Graves' goitres. Dendritic cells could be identified in all thyroids studied and were positioned underneath the thyrocytes in between the follicles. Skin dendritic cells travel via lymphatics to draining lymph nodes, thus forming an antigen presenting cell system. It is likely that a similar cell system exists on the level of the thyroid for dendritic cells have also been detected in thyroid draining lymph nodes. In normal thyroid tissue of both human and rat dendritic cells were relatively scarce. During the initial phases of the thyroid autoimmune response in the BBW rat (before the appearance of Tg-antibodies in the circulation) numbers of thyroid dendritic cells increased. Intrathyroidal T-helper cells, B-cells or plasma cells could not be found. The thyroid draining lymph node contained large numbers of plasma cells. During the later stages of the thyroid autoimmune response in the BB/W rat (after the appearance of Tg-antibodies in the circulation) and in Graves' goitres dendritic cells were not only present in high number, but 20-30% were seen in contact with now-present intrathyroidal T-helper lymphocytes.(ABSTRACT TRUNCATED AT 250 WORDS)

    The occurrence of autoimmune thyroid disorders among patients with coeliac disease (CD) is well documented, but the exact prevalence of CD among patients with autoimmune thyroid diseases (ATD) is as yet unclear. We screened 150 newly diagnosed patients with ATD by serum endomysial antibody detection (EmA). In 5 subjects (3.3%) EmA positivity was found; all underwent jejunal biopsy. On gluten-free diet an excellent clinical and histological response was recorded with an improvement of hypothyroidism and reduction of the thyroxine dosage. Our data suggest a significant high prevalence (3.3%) of CD in patients with ATD, in particular with Hashimoto's thyroiditis.

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

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

    Risk coefficients for thyroid disorders have been developed for both 131 I and external x or gamma low-LET radiation. A linear, no-threshold model has been used for thyroid neoplasms. A linear, threshold model has been used for other thyroid disorders. Improvements since the Reactor Safety Study were made possible by relevant new animal and human data. Major changes are as follows. Animal data are used to supplement the human experience where necessary. A specific risk estimate model is used for thyroid neoplasms, which accounts for observed effects of gender and age at exposure on risk. For thyroid cancer, the basis of the risk coefficients is the experience of North Americans following x-irradiation for benign disease in childhood. This recognizes possible differences in susceptibility in people of different heritage. A minimum induction period for thyroid neoplasms following irradiation is used to define periods at risk. An upper bound risk coefficient for cancer induction following exposure to 131 I is based on human experience at relatively low dose exposures. While the overall lifetime risks of death due to thyroid cancer are consistent with projections by the ICRP, BEIR III, and UNSCEAR Reports, the current model permits greater flexibility in determining risk for population subgroups. 88 references, 8 tables

    Hu-antigen R (HuR) is considered to play a crucial role in tumor formation and growth by binding to mRNAs encoding proteins such as Cyclooxygenase-2 (COX-2) and inducing their expression via mRNA stabilization and/or altered translation. The present study aimed to evaluate the clinical significance of HuR and COX-2 proteins’ expression in human benign and malignant thyroid lesions. HuR and COX-2 proteins’ expression was assessed immunohistochemically on paraffin-embedded thyroid tissues obtained from 98 patients with benign (n = 48) and malignant (n = 50) lesions and was statistically analyzed with clinicopathological parameters, follicular cells’ proliferative capacity and recurrence risk rate. Enhanced HuR and COX-2 expression was significantly more frequently observed in malignant compared to benign thyroid lesions (p = 0.0073 and p = 0.0016, respectively), as well as in papillary carcinomas compared to hyperplastic nodules (p = 0.0039 and p = 0.0009, respectively). Positive associations of both HuR and COX-2 expression with follicular cells’ proliferation rate were also noted (p = 0.0087 and p = 0.0127, respectively). In malignant thyroid lesions, elevated COX-2 expression was significantly associated with female patients’ gender (p = 0.0381) and the presence of lymph node metastases (p = 0.0296). The present data support evidence that both HuR and COX-2 may be involved in the malignant state of thyroid neoplasia and may be utilized in the diagnosis of malignant thyroid tumors.

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

  10. Basics of Radiation Biology When Treating Hyperproliferative Benign Diseases

    2017-05-01

    Full Text Available For decades, low- and moderate-dose radiation therapy (RT has been shown to exert a beneficial therapeutic effect in a multitude of non-malignant conditions including painful degenerative muscoloskeletal and hyperproliferative disorders. Dupuytren and Ledderhose diseases are benign fibroproliferative diseases of the hand/foot with fibrotic nodules and fascial cords, which determine debilitating contractures and deformities of fingers/toes, while keloids are exuberant scar formations following burn damage, surgery, and trauma. Although RT has become an established and effective option in the management of these diseases, experimental studies to illustrate cellular composites and factors involved remain to be elucidated. More recent findings, however, indicate the involvement of radiation-sensitive targets like mitotic fibroblasts/myofibroblasts as well as inflammatory cells. Radiation-related molecular mechanisms affecting these target cells include the production of free radicals to hamper proliferative activity and interference with growth factors and cytokines. Moreover, an impairment of activated immune cells involved in both myofibroblast proliferative and inflammatory processes may further contribute to the clinical effects. We here aim at briefly describing mechanisms contributing to a modulation of proliferative and inflammatory processes and to summarize current concepts of treating hyperproliferative diseases by low and moderate doses of ionizing radiation.

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

    1979-01-01

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

    To examine the relationships between sex and symmetry in the context of disease activity, severity, and thyroid status in thyroid eye disease. Retrospective chart review of 31 men and 31 women with untreated thyroid eye disease. Subjective complaints, smoking status, thyroid status, and objective findings pertinent to the clinical activity score (CAS) and "NO SPECS" classification were recorded. Overall disease asymmetry was defined as having simultaneous asymmetry of both more than one symptom and more than one external finding. Asymmetry was compared across sex and thyroid status. CAS and NO SPECS severity were compared across sex, symmetry, and thyroid status. Asymmetric appearance was reported by 58% of men and 19% of women. Asymmetric proptosis (>2 mm difference) was seen in 45% of men and 23% of women (P=0.036). Overall asymmetry was seen in 55% of men and 19% of women (P=0.017). Thyroid status and sex had a combined effect on symmetry, as 15 of 16 hyperthyroid females (94%) demonstrated symmetric disease. Average NO SPECS severity was 3.5 (standard deviation [SD] 1.4) in men and 3.3 (SD 1.1) in women (P=0.51), and was 3.8 (SD 1.4) in asymmetric patients versus 3.2 (SD 1.3) in symmetric patients (P=0.08). The CAS was higher in asymmetric than symmetric patients (1.84 versus 0.97; P=0.012). Men demonstrated more asymmetric disease (proptosis and overall asymmetry) than women, while hyperthyroid females demonstrated more symmetry than euthyroid and hypothyroid males and females. NO SPECS severity score was unaffected by sex, thyroid status, or symmetry. Asymmetric patients demonstrated higher clinical activity scores.

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

    2013-07-01

    Thyroid hormones produced by the thyroid gland help regulation of the body's metabolism. A variety of methods have been proposed in the literature for thyroid disease classification. As far as we know, clustering techniques have not been used in thyroid diseases data set so far. This paper proposes a comparison between hard and fuzzy clustering algorithms for thyroid diseases data set in order to find the optimal number of clusters. Different scalar validity measures are used in comparing the performances of the proposed clustering systems. To demonstrate the performance of each algorithm, the feature values that represent thyroid disease are used as input for the system. Several runs are carried out and recorded with a different number of clusters being specified for each run (between 2 and 11), so as to establish the optimum number of clusters. To find the optimal number of clusters, the so-called elbow criterion is applied. The experimental results revealed that for all algorithms, the elbow was located at c=3. The clustering results for all algorithms are then visualized by the Sammon mapping method to find a low-dimensional (normally 2D or 3D) representation of a set of points distributed in a high dimensional pattern space. At the end of this study, some recommendations are formulated to improve determining the actual number of clusters present in the data set. Copyright © 2013 Elsevier Ireland Ltd.

    Full Text Available Autoimmune thyroid diseases (AITD are common, affecting 2-5% of the general population. Individuals with positive thyroid peroxidase antibodies (TPOAbs have an increased risk of autoimmune hypothyroidism (Hashimoto's thyroiditis, as well as autoimmune hyperthyroidism (Graves' disease. As the possible causative genes of TPOAbs and AITD remain largely unknown, we performed GWAS meta-analyses in 18,297 individuals for TPOAb-positivity (1769 TPOAb-positives and 16,528 TPOAb-negatives and in 12,353 individuals for TPOAb serum levels, with replication in 8,990 individuals. Significant associations (P<5×10(-8 were detected at TPO-rs11675434, ATXN2-rs653178, and BACH2-rs10944479 for TPOAb-positivity, and at TPO-rs11675434, MAGI3-rs1230666, and KALRN-rs2010099 for TPOAb levels. Individual and combined effects (genetic risk scores of these variants on (subclinical hypo- and hyperthyroidism, goiter and thyroid cancer were studied. Individuals with a high genetic risk score had, besides an increased risk of TPOAb-positivity (OR: 2.18, 95% CI 1.68-2.81, P = 8.1×10(-8, a higher risk of increased thyroid-stimulating hormone levels (OR: 1.51, 95% CI 1.26-1.82, P = 2.9×10(-6, as well as a decreased risk of goiter (OR: 0.77, 95% CI 0.66-0.89, P = 6.5×10(-4. The MAGI3 and BACH2 variants were associated with an increased risk of hyperthyroidism, which was replicated in an independent cohort of patients with Graves' disease (OR: 1.37, 95% CI 1.22-1.54, P = 1.2×10(-7 and OR: 1.25, 95% CI 1.12-1.39, P = 6.2×10(-5. The MAGI3 variant was also associated with an increased risk of hypothyroidism (OR: 1.57, 95% CI 1.18-2.10, P = 1.9×10(-3. This first GWAS meta-analysis for TPOAbs identified five newly associated loci, three of which were also associated with clinical thyroid disease. With these markers we identified a large subgroup in the general population with a substantially increased risk of TPOAbs. The results provide insight into why

    Objective: The aim of this study is to investigate the diagnostic accuracy of muscle-to-nodule strain ratio (MNSR) in the differentiation of benign and malignant thyroid nodules and to see if there was a difference between MNSR and parenchyma-to-nodule strain ratios (PNSR) in diagnosis. Methods: A total of 106 consecutive patients (88 women and 18 men; age range 19–79 years) with thyroid nodules were prospectively examined using ultrasound and sonoelastography before the fine-needle aspiration biopsy. The mean MNSR and PNSR were calculated for each nodule and the elasticity score was determined according to four-point scoring system. Results: According to the four-point scoring system, 44 of the 83 benign nodules had a score of one or two while 22 of the 23 malignant nodules had a score of three or four (p < 0.001). Using ROC analysis, the best cutoff point for MNSR 1.85 and for PNSR 3.14 was calculated. The sensitivity and specificity for the MNSR were 95.6%, 92.8%, respectively; for the PNSR were 95.6%, 93.4%, respectively, when the best cutoff points were used (p < 0.001). The κ value for the PNSR and MNSR methods was 0.87, which indicated an almost perfect agreement (p < 0.001). Conclusions: Sonoelastography has a high diagnostic accuracy in the differentiation of benign and malignant thyroid nodules. There was no significant difference between MNSR and PNSR in the differentiation of benign and malignant thyroid nodules. Therefore, we think that MNSR could safely be used in situations where PNSR could not be used.

    This study is a dedicated 2D-shear wave elastography (2D-SWE) review aimed at systematically eliciting up-to-date evidence of its clinical value in differential diagnosis of benign and malignant thyroid nodules. PubMed, Web of Science, and Scopus databases were searched for studies assessing the diagnostic value of 2D-SWE for thyroid malignancy risk stratification published until December 2016. The retrieved titles and abstracts were screened and evaluated according to the predefined inclusion and exclusion criteria. Methodological quality of the studies was assessed using the Quality Assessment of Studies of Diagnostic Accuracy included in Systematic Review 2 (QUADAS-2) tool. Extracted 2D-SWE diagnostic performance data were meta-analyzed to assess the summary sensitivity, specificity, and area under the receiver operating characteristic curve. After stepwise review, 14 studies in which 2D-SWE was used to evaluate 2851 thyroid nodules (1092 malignant, 1759 benign) from 2139 patients were selected for the current study. Study quality on QUADAS-2 assessment was moderate to high. The summary sensitivity, specificity and area under the receiver operating characteristic curve of 2D-SWE for differential diagnosis of benign and malignant thyroid nodules were 0.66 (95% confidence interval [CI]: 0.64-0.69), 0.78 (CI: 0.76-0.80), and 0.851 (Q* = 0.85), respectively. The pooled diagnostic odds ratio, negative likelihood ratio, and positive likelihood ratio were 12.73 (CI: 8.80-18.43), 0.31 (CI: 0.22-0.44), and 3.87 (CI: 2.83-5.29), respectively. Diagnostic performance of quantitative 2D-SWE for malignancy risk stratification of thyroid nodules is suboptimal with mediocre sensitivity and specificity, contrary to earlier reports of excellence.

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

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

  2. Thyroid Autoantibodies in the Cerebrospinal Fluid of Subjects with and without Thyroid Disease: Implications for Hashimoto’s Encephalopathy

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

    Fibromyalgia and chronic widespread pain syndromes are among the commonest diseases seen in rheumatology practice. Despite advances in the management of these conditions, they remain significant causes of morbidity and disability. Autoimmune thyroid disease is the most prevalent autoimmune disorder, affecting about 10 % of the population, and is a recognized cause of fibromyalgia and chronic widespread pain. Recent reports are shedding light on the mechanisms of pain generation in autoimmune thyroid disease-associated pain syndromes including the role of inflammatory mediators, small-fiber polyneuropathy, and central sensitization. The gradual elucidation of these pain pathways is allowing the rational use of pharmacotherapy in the management of chronic widespread pain in autoimmune thyroid disease. This review looks at the current understanding of the prevalence of pain syndromes in autoimmune thyroid disease, their likely causes, present appreciation of the pathogenesis of chronic widespread pain, and how our knowledge can be used to find lasting and effective treatments for the pain syndromes associated with autoimmune thyroid disease.

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

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

    As the world population becomes progressively older, the overall incidence of chronic subdural hematoma (CSDH) is increasing. Peak age of onset for CSDH has also increased, and recently the 80-year-old level has a peak. Many patients with CSDH have had prior treatment with anticoagulants and antiplatelet drugs, which have an accompanying risk of CSDH. In elderly patients with CSDH, symptoms of cognitive change (memory disturbance, urinary incontinence, and decreased activity) and disturbance of consciousness at admission were more frequent compared to younger patients with CSDH. The literature actually offers conflicting advice regarding CSDH treatment; however, burr hole surgery with drainage under local anesthesia is the most common surgical procedure, even in elderly patients. The recurrence rate of CSDH has not decreased over recent decades, and it has ranged from 0.36-33.3%. Outcomes in patients over 75 years old was significantly worse than for those younger than 75. Moreover, long-term outcomes for elderly patients with CSDH are poor. CSDH in the elderly is no longer a benign disease. In the future, it will be important for us to understand the mechanisms of onset and recurrence of CSDH and to develop more effective medical treatments and noninvasive surgical techniques for elderly patients.

    Over the past 30 years, the field of endoscopy has witnessed several advances. With the advent of endoscopic mucosal resection, removal of large mucosal lesions have become possible. Thereafter, endoscopic submucosal resection was refined, permitting en bloc removal of large superficial neoplasms. Such techniques have facilitated the development of antireflux mucosectomy, a promising novel treatment for gastroesophageal reflux. The introduction and use of over the scope clips has allowed for endoscopic closure of defects in the gastrointestinal tract, which were traditionally treated with surgical intervention. With the development of per-oral endoscopic myotomy (POEM), the treatment of achalasia and spastic disorders of the esophagus have been revolutionized. From the submucosal tunnelling technique developed for POEM, Per oral endoscopic tumor resection of subepithelial tumors was made possible. Simultaneously, advances in biotechnology have expanded esophageal stenting capabilities with the introduction of fully covered metal and plastic stents, as well as biodegradable stents. Once deemed a primarily diagnostic tool, endoscopy has quickly transcended to a minimally invasive intervention and therapeutic tool. These techniques are reviewed with regards to their application to benign disease of the esophagus. PMID:25992187

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

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

    Full Text Available We here analyzed the prevalence of extra-thyroidal malignancies (EM in 6,386 female patients affected by different thyroid disease (TD. At first, an age-matched analysis of EM in all patients was performed. We then evaluated EM prevalence in four TD diagnostic categories: non-nodular TD (n = 2,159; solitary nodule (n = 905; multinodular TD (n = 2,871; differentiated thyroid cancers (n = 451. Finally, patients were grouped based on the absence (n = 3,820 or presence of anti-thyroglobulin (TgAb and/or anti-thyroperoxidase (TPOAb (n = 2,369, or anti-Thyroid Stmulating Hormone (TSH receptor autoantibodies (n = 197. A total of 673 EM were recorded. EM prevalence in TD patients was higher compared to the general population (Odds Ratio, OR 3.21 and the most frequent EM was breast cancer (OR 3.94, followed by colorectal (OR 2.18, melanoma (OR 6.71, hematological (OR 8.57, uterus (OR 2.52, kidney (OR 3.40 and ovary (OR 2.62 neoplasms. Age-matched analysis demonstrated that the risk of EM was maximal at age 0-44 yr (OR 11.28, remaining lower, but significantly higher that in the general population, in the 45-59 and 60-74 year age range. Breast and hematological malignancies showed an increased OR in all TD, while other cancers associated with specific TD. An increased OR for melanoma, breast and hematological malignancies was observed in both TPOAb and/or TgAb autoantibody negative and positive patients, while colorectal, uterus, kidney and ovary cancers showed an increased OR only in thyroid autoantibody negative patients. In conclusions, women affected by both benign and malignant TD, especially at a younger age and in absence of thyroid autoimmunity, have an increased risk of developing primary EM, thus requiring a careful follow-up and surveillance.

  11. Concomitant Graves' disease and Hashimoto's thyroiditis, presenting as primary hypothyroidism.

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

    To explore the relationship between maternal milk and serum thyroid hormones in patients with thyroid-related diseases. Serum and breast milk samples were collected from 56 breastfeeding mothers. Milk and serum free triiodothyronine (FT3), free thyroxine (FT4), triiodothyronine(T3), thyroxine (T4), and thyrotrophin (TSH) were determined, and T3/T4 was calculated. Using the serum thyroid hormones as the independent variables and milk thyroid hormones as the dependent variables, we performed linear regression analysis. The milk FT3, FT4, T3, T4, TSH, and T3/T4 were (2.30 ± 0.82) pg/ml ,(0.45 ± 0.26) ng/dl, (0.35 ± 0.20) ng/ml, (2.96 ± 1.55) Μg/dl, (0.12 ± 0.08) ΜU/ml, and 0.12 ± 0.04, respectively. Milk FT3 (r = 0.778, P = 0.000), T3 (r = 0.603, P = 0.000), T4 (r = 0.485, P = 0.004), and TSH (r = 0.605, P = 0.000) concentrations were positively correlated with those in serum. Thyroid hormones are present in human milk and are positively correlated with those in serum.

    Full Text Available Aim: Differential diagnosis of parenchymal thyroid diseases by gray-scale ultrasound is quite difficult for a radiologist as the findings are very similar to each other. In this study we aimed to assess some quantitative spectral Doppler parameters, resistivity index (RI, acceleration time (AT, and quantitative elastography [shear wave velocity (SWV] together to show their reliability for differential diagnosis of parenchymal thyroid diseases. Materials and Methods: We retrospectively reviewed findings of 227 patients (179 females, 48 males that underwent spectral Doppler ultrasound and acoustic radiation force impulse between October 2013 and March 2016. Ages of the patients were between 18 and 74 years (39.52 ± 12.67. Based on clinical and laboratory findings, patients were divided into five groups (N: Normal, EH: Early Hashimoto, H: Late Hashimoto, M: Nodular Thyroid Disease, HM: Hashimoto + Nodular Thyroid Disease. Detailed statistical analyses were done on parameters such as age, gender, volume information, and RI, AT (ms, SWV (m/s. Results: No significant effect of gender or volume on the differentiation of disease pattern (Chi-square test: P= 0.306, Kruskal-Wallis test: P= 0.290 was found in this study. RI (0.41 ± 0.06 and SWV values (1.19 ± 0.18 m/s were the lowest. AT values (>55 ms were the highest in EH group (area under the curve: 0.913. Existence of H decreased RI and SWV values, while it extended AT in a different thyroid disease. Conclusion: Thyroid parenchymal diseases could be classified and differentiated from each other by measuring RI, AT, and SWV values quantitatively. So, in suspicious cases, these parameters could be a reliable asset for differential diagnosis.

    Radiological and pathological correlation of the full range of benign breast lesions, with emphasis on screen-detected lesions. Detailed discussion of risk assessment. Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

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

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

    Full Text Available Objective: The incidence of thyroid cancer, the most common endocrine malignancy, has increased dramatically in the last fifty years. This article will review the standard approach to thyroid cancer treatment as well as novel therapies under investigation. We will also address potential cost considerations in the management of thyroid cancer.Study Design: A comprehensive literature search was performed.Methods: Review article.Results: The high prevalence of thyroid cancer and the availability of novel therapies for patients with metastatic disease have potential economic implications that have not been well-studied. Because many patients likely have very low morbidity from their cancers, better tools to identify the lowest risk patients are needed in order to prevent overtreatment. Improved risk stratification should include recognizing patients who are unlikely to benefit from radioactive iodine therapy after initial surgery and identifying those with indolent and asymptomatic metastatic disease that are unlikely to benefit from novel therapies. In patients with advanced incurable disease, randomized-controlled studies to assess the efficacy of novel agents are needed to determine if the costs associated with new agents are warranted.Conclusions: Health care costs associated with the increased diagnosis of thyroid cancer remain unknown but are worthy of further research.

    Thyroid disorders are associated with a wide variety of skin disorders that respond to treatment of hormone imbalance in most cases and thus are of vital importance to dermatologists. This study aimed to evaluate skin findings associated with autoimmune and nonautoimmune thyroid disease with respect to thyroid functional status and healthy controls. A total of 300 consecutive patients with either autoimmune (n = 173) or nonautoimmune (n = 127) thyroid disease and 100 healthy control subjects were included in this cross-sectional study. Data on patient demographics, thyroid function tests, and skin findings were recorded for patient and control groups. Compared to control subjects, patients had higher proportions in populations with alopecia (P respect to controls, autoimmune etiology, and thyroid functional status.

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

    Purpose: To develop a semiautomated computer-aided diagnosis (CAD) system for thyroid cancer using two-dimensional ultrasound images that can be used to yield a second opinion in the clinic to differentiate malignant and benign lesions. Methods: A total of 118 ultrasound images that included axial and longitudinal images from patients with biopsy-confirmed malignant (n = 30) and benign (n = 29) nodules were collected. Thyroid CAD software was developed to extract quantitative features from these images based on thyroid nodule segmentation in which adaptive diffusion flow for active contours was used. Various features, including histogram, intensity differences, elliptical fit, gray-level co-occurrence matrixes, and gray-level run-length matrixes, were evaluated for each region imaged. Based on these imaging features, a support vector machine (SVM) classifier was used to differentiate benign and malignant nodules. Leave-one-out cross-validation with sequential forward feature selection was performed to evaluate the overall accuracy of this method. Additionally, analyses with contingency tables and receiver operating characteristic (ROC) curves were performed to compare the performance of CAD with visual inspection by expert radiologists based on established gold standards. Results: Most univariate features for this proposed CAD system attained accuracies that ranged from 78.0% to 83.1%. When optimal SVM parameters that were established using a grid search method with features that radiologists use for visual inspection were employed, the authors could attain rates of accuracy that ranged from 72.9% to 84.7%. Using leave-one-out cross-validation results in a multivariate analysis of various features, the highest accuracy achieved using the proposed CAD system was 98.3%, whereas visual inspection by radiologists reached 94.9% accuracy. To obtain the highest accuracies, “axial ratio” and “max probability” in axial images were most frequently included in the

    Association between autoimmune thyroiditis (CLT) and thyroid cancer remains not clear. Although both diseases often occur simultaneously in histological samples, it is not yet clear whether CLT can be regarded as a risk factor for thyroid malignancy. This review focus on the known epidemiological and molecular genetics links between both diseases. Most studies have shown a significant association between thyroid cancer and positive antibodies to thyroglobulin and histological evidence of CLT, as well. Both disorders share some risk factors (greater incidence in women, in areas with adequate supply of iodine and in patients after radiotherapy of the neck) and molecular genetics linkage. For example: RET/PTC rearrangements could be more often found in carcinomas associated with CLT, but this mutation could be found in benign lesions such as CLT, as well. CLT seems to be a positive prognostic factor in patients with differentiated thyroid cancer. It is associated with less invasive forms of tumor, lower occurrence of infiltrated lymphatic nodes and a lower risk of recurrence.

    Full Text Available Introduction: Liver is involved with the synthesis of carrier proteins and metabolism of various hormones and liver diseases may, therefore, be associated with various endocrine disturbances. This study was conducted to assess thyroid and gonadal function in subjects with acute hepatitis (AH, chronic liver disease (CLD, and those who had undergone liver transplantation (LT. Materials and Methods: Patients with AH, CLD with Child-Pugh stage A (CLD-1 and Child-Pugh stage B or C (CLD-2, and LT seen at our tertiary level hospital were assessed clinically, biochemically, and for thyroid and gonadal functions besides 25 healthy controls. Results: Thyroid dysfunction and hypogonadism were present in 14 (16% and 24 (28% patients with liver diseases respectively. Among thyroid dysfunction, the commonest was sick euthyroid syndrome six (7%, followed by subclinical hypothyroidism in three patients (3.5%, subclinical hyperthyroidism and thyrotoxicosis in two patients each (2.3% and overt hypothyroidism in one patient. Among patients with LT and AH groups, the only abnormality was significantly lower total T3 compared with healthy controls. The CLD2 group had significantly lower levels of all thyroid hormones compared with controls and CLD1 group. Hypogonadism was commonest in patients with CLD-2 (14; 50% followed by LT (3; 33%, CLD-1 (4; 20%, and AH (3; 14%. Hypogonadism was predicted by older age, lower levels of serum albumin, total cholesterol, and triglycerides and higher levels of plasma glucose, serum bilirubin, aspartate transaminases, and international normalized ratio. Gonadal functions showed recovery following LT. Conclusions: Thyroid dysfunction and hypogonadism form an important part of the spectrum of acute and CLD, and patients with LT. Deterioration of synthetic functions of liver disease predicts presence of hypogonadism.

    In order to assess the utility of 67gallium citrate in delineating malignant pleural mesothelioma from benign asbestos-related pleural disease, 49 patients with malignant mesothelioma and 16 with benign asbestos-related pleural disease were studied. Seven patients with malignant mesothelioma had no history of asbestos exposure, while the remaining 58 patients were exposed. Forty-three of the 49 patients (88%) with malignant mesothelioma had a positive 67gallium scan including 36 of the 42 (86%) patients with asbestos exposure and all 7 patients without a history of asbestos exposure. Three of 16 patients (19%) with benign asbestos-related pleural disease had a positive scan. 67Gallium radionuclide imaging is nonspecific but may be valuable in noninvasive monitoring of asbestos-exposed populations, which have a high risk for the late development of benign and/or malignant pleural disease

    Celiac disease (CD) is associated with thyroid autoimmunity and other autoimmune diseases. However, data are lacking regarding the relationship between thyroid autoimmunity and thyroid function, especially in regard to CD. Our aim was to investigate the impact of thyroid autoimmunity on thyroid function in 12-year-old children with CD compared to their healthy peers. A case-referent study was conducted as part of a CD screening of 12-year-olds. Our study included 335 children with CD and 1,695 randomly selected referents. Thyroid autoimmunity was assessed with antibodies against thyroid peroxidase (TPOAb). Thyroid function was assessed with thyroid stimulating hormone and free thyroxine. TPOAb positivity significantly increased the risk of developing hypothyroidism in all children. The odds ratios (with 95% confidence intervals) were: 5.3 (2.7-11) in healthy 12-year-olds, 10 (3.2-32) in screening-detected CD cases, 19 (2.6-135) in previously diagnosed CD cases, and 12 (4.4-32) in all CD cases together. Among children with TPOAb positivity, hypothyroidism was significantly more common (odds ratio 3.1; 95% CI 1.03-9.6) in children with CD (10/19) than in children without CD (12/46). The risk of thyroid dysfunction due to thyroid autoimmunity is larger for those with CD than their healthy peers. Our study indicate that a gluten-free diet does not reduce the risk of thyroid dysfunction. Further studies are required for improved understanding of the role of the gluten-free diet for the risk of autoimmune diseases in children with CD.

    Immunotherapies and targeted therapies are frequently associated with thyroid dysfunction, which is in contrast with the rare thyroid abnormalities induced by cytotoxic agents. Immunotherapy with NY-ESO-1, a tumor-associated antigen expressed by a number of malignancies, was reported to trigger hyperthyroidism or hypothyroidism in two HLA-A2 patients with ovarian cancer. We describe now a case of Graves' disease triggered by NY-ESO-1 in a HLA-A2-negative woman. A 32-year-old woman with a synovial sarcoma received radiotherapy, chemotherapy, and finally NY-ESO-1 vaccine. The patient was found to have HLA A11/A33(19), B13/B56(22), Cw3/-. One month after the beginning of immunotherapy, thyroid dysfunction was clinically suspected and Graves' disease was biochemically confirmed. Fearful of the antithyroid drugs' side effects, the patient was treated with a beta-blocker (propranolol, 80-20 mg/day). As hyperthyroidism progressively worsened, the patient underwent total thyroidectomy. We hypothesized that NY-ESO-1 shared partial homology with thyroid autoantigens (the so-called molecular mimicry mechanism) and that at least one pair of homologous sequences contained amino acid sequence binding motifs to a restricted number of HLA molecules. We used BLAST software to search amino acid sequence homologies between NY-ESO-1 and thyroid autoantigens (thyrotropin receptor [TSH-R], thyroperoxidase, and thyroglobulin), and the HLA ligand/motif database to look for HLA/T-cell receptor binding motifs in the regions of NY-ESO-1 and thyroid autoantigens that were homologous. We found 15 epitopic regions of NY-ESO-1 homologous to 15 regions of thyroid autoantigens, some of which epitopic: 5 of TSH-R, 8 of thyroglobulin, and 2 of thyroperoxidase. These homologous sequences contain binding motifs belonging to several HLA class I antigens, including HLA A2 and the patient's A11 and A33. Genetically predisposed patients who receive NY-ESO-1 vaccination are at risk to develop thyroid

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

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

    The complex relationship between pregnancy and thyroid function, and its clinical effect on mother and baby, continued to stimulate research in 2011. Key advances were made on three important issues: how long maternal thyroid function affects fetal thyroid hormone levels; whether thyroid autoimmunity affects pregnancy outcome; and the prevalence of permanent hypothyroidism after postpartum thyroiditis.

    Full Text Available The long-term results of subtotal resection of thyroid gland on 82 patients with Graves' disease were studied. There was analysed the influence of three factors on outcome at Graves' disease: volume of a thyroid gland before operation, morphological structure of thyroid tissue and volume of thyroid remnant. Outcomes of subtotal resection of thyroid gland were studied on the basis of thyrotropic hormone level of blood in 3, 6, 12 months, 2 and 3 years after operation. Based on research it has been established that the volume of thyroid gland before operation does not influence to outcome of subtotal resection of thyroid gland with Graves' disease. Morphological changes of removed thyroid tissue in the form of colloidal nodules at patients with Graves' disease statistically significantly raise risk of development of postoperative complications after subtotal resection of thyroid gland. The surgeon defining the volume of thyroid rem-nant durng the operation could be mistaken as towards it's increase so towards it's reduction, with an average deviation about 35%. Various outcomes of subtotal resection of thyroid gland at the same volume of thyroid remnant let us conclude that this out-come depends more on intensity of autoimmune process rather than on the volume of thyroid remnant. According modern views to aetiology and patogenesis of Graves' disease, the optimum volume of operation at Graves' disease is thyroidectomy.

    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.

    This is the first case of Graves' disease in an adolescent with lingual and prelaryngeal dual congenital ectopia and no orthotopic thyroid gland identified by technetium-99m-pertechnetate (99mTcO-4) SPET/CT imaging in a 15 years old boy. After 8 weeks treatment with methimazole, Graves' disease subsided. Fine needle aspiration cytology of the mass revealed the normal colloid and normal follicular cells without an atypia or lymphoid elements, suggesting a benign ectopic thyroid gland. In conclusion, there is no report in the literature with DETT lingual and prelaryngeal absence of orthotopic thyroid tissue and Graves' disease as in our case. This case also highlights the potential ascendancy of 99mTcO-4 SPET/CT in diagnosing the DETT.

  7. Serum TBG and T4 concentration in non-thyroidal diseases

    1983-01-01

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

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

    {sup 68}Ga-Prostate specific membrane antigen- N,N′-bis[2-hydroxy-5-(carboxyethyl)benzyl]ethylenediamine-N,N′-diacetic acid- positron emission tomography/computed tomography or 68 Ga- HBED-CC-PSMA PET/CT, popularly known as PSMA PET/CT, is able to detect a small volume of recurrent prostate carcinoma (PC) when there is a prostate specific antigen (PSA) rise on follow-up after prostatectomy or other definitive treatment for PC. The use of PSMA PET/CT in the initial staging in PC is uncertain at this time. Clinical studies are underway to define its exact role in the management of the disease. At the same time it is important to be aware of unexpected sites of uptake of this ligand. We present here the case of a 62-year-old male patient who underwent prostatectomy for adenocarcinoma prostate. He also had a long-standing left solitary thyroid nodule (STN). Four months after surgery, he had a rising trend in serum PSA levels on three occasions, but the absolute value was less than 4 at all times. He underwent a {sup 68}Ga-PSMA-HBED-CC PET/CT, but it did not reveal any recurrent/metastatic site of disease. However, there was increased tracer uptake in the left STN. Fine needle aspiration cytology revealed features of atypia of undetermined significance, Bethesda category III. The patient underwent a left hemithyroidectomy and the histopathology showed features of a follicular adenoma.

    The study involved 309 liquidators of the accident at the Chernobyl Atomic Power Plant (192 patients were investigated in 1990-1991 and 117 in 1992-1994). Nodular goiter and autoimmune thyroiditis (diffuse and nodular forms) against the background of thyroid hyperplasia occupy the leading place among the thyroid diseases in these patients. Thyroid cancer developed mainly in those liquidators who stayed in the zone of the accident during 'iodine' period. The incidence of thyroid pathology (mainly that autoimmune character and thyroid cancer) have increased in the participants of the Chernobyl accident clean-up recently

    Thyroid functional disease, and in particular hypothyroidism, is highly prevalent among chronic kidney disease (CKD) and end-stage renal disease (ESRD) patients. In the general population, hypothyroidism is associated with impaired cardiac contractility, endothelial dysfunction, atherosclerosis and possibly higher cardiovascular mortality. It has been hypothesized that hypothyroidism is an under-recognized, modifiable risk factor for the enormous burden of cardiovascular disease and death in CKD and ESRD, but this has been difficult to test due to the challenge of accurate thyroid functional assessment in uremia. Low thyroid hormone levels (i.e. triiodothyronine) have been associated with adverse cardiovascular sequelae in CKD and ESRD patients, but these metrics are confounded by malnutrition, inflammation and comorbid states, and hence may signify nonthyroidal illness (i.e. thyroid functional test derangements associated with underlying ill health in the absence of thyroid pathology). Thyrotropin is considered a sensitive and specific thyroid function measure that may more accurately classify hypothyroidism, but few studies have examined the clinical significance of thyrotropin-defined hypothyroidism in CKD and ESRD. Of even greater uncertainty are the risks and benefits of thyroid hormone replacement, which bear a narrow therapeutic-to-toxic window and are frequently prescribed to CKD and ESRD patients. In this review, we discuss mechanisms by which hypothyroidism adversely affects cardiovascular health; examine the prognostic implications of hypothyroidism, thyroid hormone alterations and exogenous thyroid hormone replacement in CKD and ESRD; and identify areas of uncertainty related to the interplay between hypothyroidism, cardiovascular disease and kidney disease requiring further investigation.

    2000-01-01

    At present time, there are two current trends of research on 131 I therapy for thyroid diseases. The first is extension of the application on the field of thyroid diseases. Formerly, the authors use the 131 I only on the hyperthyroidism of Graves' disease, plummer's disease or toxic nodular goiter as well as thyroid cancer, but now, also for some thyroid diseases with normal thyroid function, such as nontoxic multi-nodular goiter, simple diffuse goiter even the thyroid cyst. It seems quite rational to use the 131 I more widely, because it is really safe, easy and cheaper than others. The second trend is using 131 I combined together with other drugs in order to reduce the occurrence of hypothyroidism and enhance the therapeutic effect. Authors call it as combined therapy. Drugs recommended for such therapy are antithyroid drugs, β-adrenergic receptor blocking agents, thyroid hormone, gtucocorticoid as well as Chinese herb drugs and so on

    The coexistence of autoimmune endocrine diseases, particularly autoimmune thyroid disease and celiac disease (CD), has recently been reported. We here present a 23-year-old woman with a diagnosis of hypothyroidism due to Hashimoto's thyroiditis, autoimmune Addison's disease, and kariotypically normal spontaneous premature ovarian failure. Considering the close association between autoimmune diseases and CD, we decided to search for IgA anti-endomysium antibodies (EmA) in the serum. The positivity of EmA and the presence of total villous atrophy at jejunal biopsy allowed the diagnosis of CD. On a gluten-free diet the patient showed a marked clinical improvement accompanied, over a 3-month period, by a progressive decrease in the need for thyroid and adrenal replacement therapies. After 6 months, serum EmA became negative and after 12 months a new jejunal biopsy showed complete mucosal recovery. After 18 months on gluten-free diet, the anti-thyroid antibodies titre decreased significantly, and we could discontinue thyroid substitutive therapy. This case emphasizes the association between autoimmune polyglandular disease and CD; the precocious identification of these cases is clinically relevant not only for the high risk of complications (e.g. lymphoma) inherent to untreated CD, but also because CD is one of the causes for the failure of substitute hormonal therapy in patients with autoimmune thyroid disease.

    Diseases of the mandible affect the soft tissues aside from the osseous manifestation. This can be shown clearly and in great detail by magnetic resonance imaging (MRI). MRI is the gold standard in the diagnostic evaluation of any internal derangement of the temporomandibular joint. Dental MRI requires high resolution techniques and in some cases also intravenous administration of contrast material. These techniques allow delineation of the neurovascular bundle. In the past few years new indications were formulated, for example, the evaluation of the integrity of the inferior alveolar nerve in trauma and in radicular cysts. New quantitative methods now enable insights into the pathophysiology. The objective of this review is to communicate accepted indications for MRI of the mandible and to present innovative applications. (orig.)

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

    Degos disease manifests as 2 distinct clinical variants, malignant atrophic papulosis and benign atrophic papulosis, which are distinguished by the presence or absence of systemic disease. Both forms feature cutaneous involvement typified by erythematous papules with scar-like centers, and the classic histologic picture is described as wedge-shaped dermal necrosis overlying thrombotic vasculopathy. However, the histopathology of early lesions is distinct and more variable. A case of benign atrophic papulosis with lymphocytic vasculitis and lichen sclerosus-like features is described, and the spectrum of histologic findings in Degos disease is reviewed.

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

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

    Anamnesis and physical examination rank first in the diagnostic process of thyroid disease. They provide a basis for subsequent diagnostic procedures and treatment. This article focusses on personal, medical and familial history as well as physical examination of the neck and general clinical examination with respect to signs and symptoms of hypo- or hyperthyreoidism. In addition indications for fine-needle biopsy and biopsy technique are described. (orig.)

    Background and objective: To examine whether clinically benign multiple sclerosis patients (BMS) show similar losses of their global N-acetylaspartate (NAA) neuronal marker relative to more clinically disabled patients of similar disease duration. Methods: The whole-brain NAA concentration (WBNAA) was acquired with whole-head non-localizing proton MR spectroscopy. Fractional brain parenchymal volume (fBPV), T{sub 2} and T{sub 1} lesion loads, were obtained from the MRI in: (i) 24 BMS patients: 23.1 ± 7.2 years disease duration, median Expanded Disability Status Scale (EDSS) score of 2.0 (range: 0–3); (ii) 26 non-benign MS patients (non-BMS), 24.5 ± 7.4 years disease duration, median EDSS of 4.0 (range: 3.5–6.5); (iii) 15 healthy controls. Results: Controls’ 12.4 ± 2.3 mM WBNAA was significantly higher than the BMS's and non-BMS's 10.5 ± 2.4 and 9.9 ± 2.1 mM (both p < 0.02), but the difference between the patients’ groups was not (p > 0.4). Likewise, the controls’ 81.2 ± 4.5% fBPV exceeded the BMS and non-BMS's 77.0 ± 5.8% and 76.3 ± 8.6% (p < 0.03), which were also not different from one another (p > 0.7). BMS patients’ T{sub 1}-hypointense lesion load, 2.1 ± 2.2 cm{sup 3}, was not significantly different than the non-BMS's 4.1 ± 5.4 cm{sup 3} (p > 0.08) and T{sub 2}-hyperintense loads: 6.0 ± 5.7 cm{sup 3} and 8.7 ± 7.8 cm{sup 3}, were also not different (p > 0.1). Conclusions: WBNAA differentiates normal controls from MS patients but does not distinguish BMS from more disabled MS patients of similar disease duration. Nevertheless, all MS patients who remain RR for 15+ years suffered WBNAA loss similar to the average RR MS population at fourfold shorter disease duration suggesting relative global neuronal sparing or leveling-off of the neurodegeneration rate.

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

  5. Prevention, screening and therapy of thyroid diseases and their cost-effectiveness

    Cost-effectivness analyses focused on benign thyroid diseases are under-represented in the literature. The calculation of costs per additionally gained life year is difficult: The benefit of prevention is shifted into the distant future. The influence of an untreated subclinical thyroid disease on life expectancy can only be demonstrated by a long-term follow-up and by epidemiological databases. Iodine supplementation and programs for the prevention of tobacco smoking (primary prevention) are very cost-effective. Smoking increases the risk both of multinodular goiter and of Graves' disease. Screening programs (secondary prevention) are discussed for the laboratory parameters thyrotropin (TSH), calcium and calcitonin. TSH testing seems to be very cost-effective for epidemiological considerations in a certain lifespan (newborn, pregnancy, postpartal), older persons, hospitalisation due to acute diseases and in persons with previously elevated TPO-antibodies for TSH-values >2 mU/l, but dedicated cost-effectiveness analyses are lacking. On the other hand, the cost-effectiveness of a routine TSH testing beyond the age of 35 years has been shown by a high-quality decision analysis. Therapeutic strategies (tertiary prevention) aim at the avoidance of complications (atrial fibrillation, myocardial infarction, death for cardiac reasons) and of iatrogenic complications. Examples of a tertiary prevention are: firstly the definitive therapy of Graves' disease in patients who have on increased risk of relapse after antithyroid drugs (ATD), secondly the radioiodine therapy for subclinical hyperthyroidism and the radioiodine therapy of large goiters in older patients or in patients suffering from a relevant comorbidity. Cost-effectiveness analyses for different therapeutic strategies of Graves' disease were published using a lifelong time-horizon. The ablative radioiodine dose-regime is cost-effective as a fist line therapy if the risk of relapse after ATD exceeds 60%. (orig

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

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

    The current trend of less aggressive treatment of low-risk differentiated thyroid cancer (DTC) patients was recently challenged by a study reporting >10% disease-related mortality (DRM) in low-risk patients ablated with radioiodine activities below 54 mCi. However, this study and others were limited by incomplete data on disease severity at presentation. Whether patients presenting with low-risk disease are at risk for disease-related mortality is crucial for planning current treatment strategies. Patients with documented DRM from DTC were included from the Rabin thyroid cancer registry and the Davidoff Head and Neck cancer service databases. Disease characteristics at presentation, treatments, disease course, and cause of death were analyzed. Of 1374 patients whose charts were reviewed, 56 were confirmed to have died of DTC, and 53 had sufficient data for analysis. Median time from diagnosis to death was 9 years (range 1-36). Cause of death was related to distant metastases in 46 patients and aggressive neck disease in 7 patients. The median age at diagnosis was 62 years (range 22-83, 83% older than 45), and were initially categorized as American Thyroid Association high risk in 89% of cases (in 4 cases due to high thyroglobulin levels), intermediate risk in 6% (3 older patients with N1b disease), misclassification as benign in one case, and none was low risk. Most patients had an advanced disease stage (stage IV, 88%; III, 2%; II, 2%; I, 8%). All patients with stage I disease were presentation, all patients had aggressive disease features at presentation. None of the patients with DRM had low-risk features at presentation, supporting the current paradigm of less aggressive approach in the low-risk group. Studies analyzing mortality from thyroid cancer should stratify patients into the various risk categories based on full baseline data, including postoperative thyroglobulin levels.

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

    To determine the levels of antithyroid antibodies and thyroid hormones in the sera of patients with oral lichen planus (OLP), and to quantify the expression of thyroid proteins in OLP lesions. Venous blood samples were drawn from 110 patients with OLP who had no history of thyroid disease or levothyroxine supplementation (OLP+/LT 4 -). A random population sample of 657 healthy subjects was used as the control group. Two additional groups were used as comparators. Immunohistochemical and qPCR analyses were performed on tissue specimens collected from the patients with OLP and thyroid disease and healthy subjects. No association was found between the presence of antithyroid antibodies and OLP. More patients in the OLP+/LT 4 - group showed high levels of thyroid-stimulating hormone and low levels of free thyroxine than were seen in the control group. Thyroid-stimulating hormone receptor was more highly expressed in the OLP lesions of patients with thyroid disease than in the healthy oral mucosa. A significant number of patients with OLP who are not previously diagnosed with thyroid disease have thyroid parameters that are compatible with hypothyroidism. The expression of thyroid-stimulating hormone receptor in OLP lesions suggests that mechanisms related to autoimmune thyroid disease are involved in the aetiology of OLP.

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

    Full Text Available INTRODUCTION: Papillary carcinoma is the most common malignant thyroid neoplasm. The effect of the concurrent presence of Hashimoto's thyroiditis and papillary thyroid carcinoma remains controversial. OBJECTIVE: To evaluate the association between Hashimoto's thyroiditis and clinicopathological parameters in thyroid papillary carcinoma cases, based on an historical institutional cohort analysis. METHODS: Cross-sectional study obtained from a historical cohort, including all cases submitted to thyroidectomy for papillary thyroid carcinoma in a single institution during an 11-year period study. RESULTS: A total of 417 patients with papillary thyroid carcinoma were enrolled; 148 (35.4% also had Hashimoto's thyroiditis. A female predominance among cases associated to Hashimoto's thyroiditis was observed. The thyroid tumor, in cases associated with Hashimoto's thyroiditis, had a smaller mean diameter, lower frequency of extra-thyroid extension, and earlier clinicopathological staging. CONCLUSIONS: A high proportion of papillary thyroid carcinoma cases are associated with Hashimoto's thyroiditis. There are associations among these cases with several histopathological factors already recognized for their prognostic value, which by themselves could impact outcomes.

    In 20 males with Stage 2 hypertensive disease, effects of 2-week-, 2-, and 6-month monotherapy with nadolol given in doses 40 to 160 mg daily were examined on the levels of thyroidal hormones (T 3 and T 4 ) and thyroid-stimulating hormone by means of radioimmunoassay. At the all stages of the therapy, the mean values of the examined parameters were significantly unchanged. Nadolol was found to cause a decrease in T 3 concentrations at its high baseline values (r=-0.57; p 3 levels in most cases. An inverse relationship was established between the altered serum T 3 levels and the thyroid-stimulating hormone concentration

    The visualization of suppressed thyroid tissue in Plummer's disease was studied by 99m Tc-MIBI thyroid imaging. 20 patients of Plummer's disease with totally or partially suppressed normal thyroid tissue were studied firstly by 99m TcO 4 - and then by 99m Tc-MIBI thyroid imaging. The suppressed tissue was clearly visualized in 8 out of 9 cases with totally suppressed normal thyroid tissue, while in 11 cases with partially suppressed normal thyroid tissue. The suppressed tissue became clearer in 8 and no change in 3 as compared with their 99m TcO 4 - imaging. The results suggested that 99m Tc-MIBI thyroid imaging may be used as a substitute for post-TSH stimulation imaging in the diagnosis of Plummer's disease. The method is relatively simple and has no TSH-related allergic reaction

    Graves’ disease is an autoimmune disorder that causes hyperthyroidism because of autoantibodies that bind to the thyroid-stimulating hormone receptor (TSHR) on the thyroid gland, triggering thyroid hormone release. The physiological control of thyroid hormone homeostasis by the feedback loops involving the hypothalamus–pituitary–thyroid axis is disrupted by these stimulating autoantibodies. To reset the endogenous thyrotrophic feedback control, we designed a synthetic mammalian gene circuit that maintains thyroid hormone homeostasis by monitoring thyroid hormone levels and coordinating the expression of a thyroid-stimulating hormone receptor antagonist (TSHAntag), which competitively inhibits the binding of thyroid-stimulating hormone or the human autoantibody to TSHR. This synthetic control device consists of a synthetic thyroid-sensing receptor (TSR), a yeast Gal4 protein/human thyroid receptor-α fusion, which reversibly triggers expression of the TSHAntag gene from TSR-dependent promoters. In hyperthyroid mice, this synthetic circuit sensed pathological thyroid hormone levels and restored the thyrotrophic feedback control of the hypothalamus–pituitary–thyroid axis to euthyroid hormone levels. Therapeutic plug and play gene circuits that restore physiological feedback control in metabolic disorders foster advanced gene- and cell-based therapies. PMID:26787873

    Full Text Available Clear cell renal cell carcinoma (CCRCC is the most common origin for metastasis in the thyroid. A 51-year-old woman was referred to our hospital for a subcarinal lesion. Ten years before, the patient had undergone a nephrectomy for CCRCC. Whole-body fluorodeoxyglucose positron emission tomography revealed elevated values in the thyroid gland, while the mediastinum was normal. An endoscopic ultrasonography-guided fine-needle aspiration biopsy of the mediastinal mass was consistent with CCRCC, and this was confirmed after resection. The thyroidectomy specimen also revealed lymphocytic thyroiditis, nodular hyperplasia, one follicular adenoma, two papillary microcarcinomas, and six foci of metastatic CCRCC involving both thyroid lobes. Curiously two of the six metastatic foci were located inside two adenomatoid nodules (tumor-in-tumor. The metastatic cells were positive for cytokeratins, CD10, epidermal growth factor receptor, and vascular endothelial growth factor receptor 2. No BRAF gene mutations were found in any of the primary and metastatic lesions. The patient was treated with sunitinib and finally died due to CCRCC distant metastases 6 years after the thyroidectomy. In CCRCC patients, a particularly prolonged survival rate may be achieved with the appropriate therapy, in contrast to the ominous prognosis typically found in patients with thyroid metastases from other origins.

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

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

    The association between deep vein thrombosis (DVT) and the hypercoagulable state is a well-established entity. However, the association between saphenous vein thrombophlebitis and coagulation abnormalities has not been investigated. Although thrombosis of varicose veins typically runs a benign course, phlebitis of the saphenous system may propagate to the deep system or saphenofemoral junction that requires more aggressive therapy. Given the potential similarity in clinical outcome between saphenous vein thrombophlebitis (SVT) and DVT, we have investigated the coagulation profile of patients presenting with isolated SVT. Seventeen consecutive patients who presented to our vascular laboratory with isolated SVT had a coagulation profile performed that included antithrombin III (AT III), protein C (PC), protein S (PS) antigen and activity levels, activated protein C (APC) resistance, factor V DNA mutation, and coagulation factors II and X. All patients had duplex scans performed on both the superficial and deep venous systems. Patients with SVT only were treated with nonsteroidal antiinflammatory drugs (NSAIDs) and warm soaks as outpatients, whereas those patients found to have DVT or a clot at the saphenofemoral junction were fully anticoagulated with heparin and coumadin therapy. All 17 patients had at least one repeat coagulation profile performed up to 5 months after their SVT occurrence to ensure that the results of hypercoagulability were not transient. Ten (59%) of the 17 patients with SVT had abnormal coagulation profiles on initial presentation. All 10 patients who were hypercoagulable had repeat tests and 6 (35%) remained abnormal. Four patients who had abnormal results converted to normal values. Seven patients with normal coagulation profiles on initial presentation had repeat tests and all remained normal. The incidence of the hypercoagulable state in patients with SVT is high. Thirty-five percent of patients with isolated SVT had consistently abnormal

    Full Text Available Multiphoton microscopy has attracted increasing attention and investigations in the field of breast cancer, based on two-photon excited fluorescence (TPEF and second-harmonic generation (SHG. However, the incidence of breast benign diseases is about 5 to 10 times higher than breast cancer; up to 30% of women suffer from breast benign diseases and require treatment at some time in their lives. Thus, in this study, MPM was applied to image fibroadenoma and fibrocystic lesion, which are two of the most common breast benign diseases. The results show that MPM has the capability to identify the microstructure of lobule and stroma in normal breast tissue, the interaction of compressed ducts with surrounding collagen fiber in fibroadenoma, and the architecture of cysts filled with cystic fluid in fibrocystic disease. These findings indicate that, with integration of MPM into currently accepted clinical imaging system, it has the potential to make a real-time diagnosis of breast benign diseases in vivo, as well as breast cancer.

  4. Molecular mechanisms of thyroid tumorigenesis

    Thyroid nodules are the most frequent endocrine disorder and occur in approximately 30% of the German population. Thyroid nodular disease constitutes a very heterogeneous entity. A striking diversity of possible functional and morphological features of a thyroid tumour derived from the same thyroid ancestor cell, is a hallmark of thyroid tumorigenesis and is due to specific genetic alterations. Defects in known candidate genes can be found in up to 70% of differentiated thyroid carcinomas and determine the respective cancer phenotype. Papillary thyroid cancers (PTC) harbour BRAF (or much less frequently RAS) mutations in sporadically occurring tumours, while radiation-induced PTC display chromosomal rearrangements such as RET, TRK, APR9 / BRAF. These genetic events results in constitutive MAPKinase activation. Follicular thyroid cancers (FTC) harbour RAS mutations or PAX8/ PPARγ rearrangements, both of which, however have also been identified in follicular adenoma. In addition, recent studies show, that activation of PI3K/AKT signalling occurs with high frequency in follicular thyroid tumours. Undifferentiated (anaplastic) thyroid cancers (ATC) display genetic features of FTC or PTC, in addition to aberant activation of multiple tyrosinkinase pathways (overexpression or mutations in PI3K and MAPK pathways). This underscores the concept of a sequential evolution of ATC from differentiated thyroid cancer, a process widely conceived to be triggered by p53 inactivation. In contrast, the molecular pathogenesis of benign thyroid tumours, in particular cold thyroid nodules is less known, except for toxic thyroid nodules, which arise from constitutive activation of cAMP signalling, predominantly through TSHR mutations.

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

    We evaluate the feasibility of optical coherence tomography (OCT) and optical coherence microscopy (OCM) for imaging of benign and malignant thyroid lesions ex vivo using intrinsic optical contrast. Thirty four thyroid gland specimens were imaged from 17 patients, covering a spectrum of pathology, ranging from normal thyroid to neoplasia and benign disease. The integrated OCT and OCM imaging system allows seamlessly switching between low and high magnifications, in a way similar to traditional microscopy. Good correspondence was observed between optical images and histological sections. The results provide a basis for interpretation of future OCT and OCM images of the thyroid tissues and suggest the possibility of future in vivo evaluation of thyroid pathology.

    The thyroid is a vascular endocrine gland with two lateral lobes connected by a narrow, median isthmus. Although a wide range of congenital anomalies of the thyroid gland has been reported in the literature, agenesis of the thyroid isthmus is a very rare congenital anomaly. Thyroid isthmus agenesis does not manifest clinical symptoms, and it can be confused with other thyroid pathologies. We describe a patient with no isthmus of the thyroid, associated with Graves-Basedow disease. Thyroid isthmus agenesis should be kept in mind in order for surgical procedures involving thyroid pathologies to be carried out safely. PMID:23346452

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

    The prevalence of thyroid diseases was studied in the ENT department of Kobe Teishin Hospital. Between January 1990 and June 1994, 6,348 outpatients (3,004 women and 3,344 men) visited the ENT department with problems of ear, nose, and throat. Among them 114 patients (82 women and 32 men) were revealed to have thyroid diseases (1.8%). The prevalence of thyroid diseases increased in patients over the age of 40 (4.6% for 40-80 year aged women, 1.6% for 40-80 year aged men). The male/female ratio was about 1:2.7. There was no subjective symptom in 86.8% of the patients. The prevalence of Hashimoto's thyroiditis was 53.5%, nontoxic diffuse goiter 16.7%, cyst(s) 8.8%, adenoma 7.0%, nontoxic nodular goiter 4.4%, subacute thyroiditis or acute exacerbation of Hashimoto's thyroiditis 4.4%, Graves' disease 1.8%, thyroid carcinoma 1.8%, adenomatous goiter 0.8%, and primary hypothyroidism 0.8%. Visible goiter was observed in only 5 patients and 93% of the patients had palpable but not visible thyroids. Therefore, it is important to palpate the thyroid gland during examination of the neck not only in women but also in men. Hashimoto's thyroiditis is thought to be increasing in frequency and is becoming a more important disease in the ENT clinic.

    Full Text Available This study sought to reveal the significance of IL-6 in papillary thyroid carcinoma by determining its circulating levels, tumoral protein, and mRNA expressions. As compared to the healthy individuals, serum IL-6 was significantly higher in patients with benign thyroid diseases and PTC. Further, its level was significantly higher in PTC patients as compared to patients with benign thyroid diseases. ROC curves also confirmed a good discriminatory efficacy of serum IL-6 between healthy individuals and patients with benign thyroid diseases and PTC. The circulating IL-6 was significantly associated with poor overall survival in PTC patients. IL-6 immunoreactivity was significantly high in PTC patients as compared to the benign thyroid disease patients. Significantly higher IL-6 mRNA expression was also observed in the primary tumour tissues of PTC patients than the adjacent normal tissues. The protein expression of IL-6 at both the circulating and tissue level correlated with disease aggressiveness in PTC patients. Moreover, a significant positive correlation was observed between the IL-6 protein and mRNA expression in the primary tumours of PTC patients. Finally in conclusion, IL-6 has an important role in thyroid cancer progression. Thus targeting IL-6 signalling can help in clinical management of thyroid carcinoma patients.

    Objective: To differentiate malignant and degenerative benign bone disease using 99m Tc- citrate scintigraphy. Methods: Thirty-nine patients (92 lesions) with confirmed malignant bone disease or degenerative benign bone disease were studied, for which the results of 99m Te-methylene diphosphonate( 99m Tc- MDP) scintigraphy were positive. 99m Tc-citrate scintigraphy was performed within a time interval of 2-7 days after 99m Tc-MDP scintigraphy. Visual analysis and semiquantitative analysis were applied. Each lesion was scored as malignant or benign, which was independently verified, using conventional techniques (histopathology, X-ray, CT, MRI and clinical follow up). Results: In visual analysis of 99m Tc-citrate imaging, most malignant lesions (35/48, 72.92%) clearly showed high radioactivity accumulation, while most benign lesions (39/44, 88.64%) had not obviously visible uptake of 99m Tc-citrate. In semiquantitative analysis of 99m Tc- citrate image, malignant lesions demonstrated a higher lesion-to-background radioisotope uptake ratio (RUR) than that of benign degenerative lesions (1.47 ± 0.42 vs. 1.09 ± 0.38, t=2.887, P 99m Tc-MDP in the two groups is of the same (1.96 ± 0.25 vs. 1.87 ± 0.21, t=1.178, P>0.20). Conclusion: 99m Tc- citrate scintigraphy is a promising method to differentiate malignant from benign degenerative lesions seen as areas of increased activity on 99m Tc-MDP bone scintigraphy.

    Abnormalities of thyroid function are commonly seen in chronic kidney disease (CKD) patients. They are associated with adverse clinical conditions such as atherosclerosis, endothelial dysfunction, inflammation and abnormal blood pressure variability. We investigated the association between thyroid disorders and endothelial function, assessed by flow-mediated dilatation (FMD) and carotid intima-media thickness (CIMT), and cardiovascular events (CVE) in CKD patients. This observational cohort study included 305 CKD (stages 1-5) patients. Routine biochemistry, including free T3, free T4 and thyroid stimulating hormone, fibroblast growth factor-23 (FGF-23) and FMD, CIMT were measured. We divided patients into four groups according to thyroid hormone status: euthyroidism, subclinical hyperthyroidism, subclinical hypothyroidism, and euthyroid sick syndrome. Fatal and composite CVE were recorded for a median 29 months. Patients with subclinical hypothyroidism had a higher prevalence of hypertension and diabetes and also were more likely to have higher values of systolic CIMT, phosphorus, intact parathormone (iPTH), FGF-23, homeostasis model assessment-insulin resistance and lower levels of FMD than euthyroid patients. In the unadjusted survival analysis, subclinical hypothyroidism and euthyroid sick syndrome were associated with an increased risk for the outcome as compared with euthyroidism [hazard ratio 30.63 (95 % confidence interval 12.27-76.48) and 12.17 (3.70-39.98), respectively]. The effects of subclinical hypothyroidism and euthyroid sick syndrome were maintained even in fully adjusted models. We demonstrated that subclinical hypothyroidism and euthyroid sick syndrome are associated with increased CVE in CKD patients. Further studies are needed to explore these issues.

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

    We report a case of bilateral metastatic melanoma to the extraocular muscles that simulated thyroid eye disease. A 71-year-old man presented with bilateral painless axial proptosis, lid retraction and left gaze restriction. Orbital CT scan demonstrated enlargement of the extraocular muscles with tendon sparing, consistent with thyroid eye disease. However, thyroid function tests and antithyroid antibodies were normal. Systemic review including orbital MRI scan determined the correct diagnosis of metastatic melanoma to the orbit. Metastatic melanoma to the orbit can simulate thyroid eye disease.

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

    Adequate thyroid hormone availability is important for an uncomplicated pregnancy and optimal fetal growth and development. Overt thyroid disease is associated with a wide range of adverse obstetric and child development outcomes. An increasing number of studies now indicate that milder forms of thyroid dysfunction are also associated with these adverse pregnancy outcomes. The definitions of both overt and subclinical thyroid dysfunction have changed considerably over the past few years, as new data indicate that the commonly used fixed upper limits of 2.5 mU/l or 3.0 mU/l for thyroid-stimulating hormone (TSH) are too low to define an abnormal thyroid function. Furthermore, some studies now show that the reference ranges are not necessarily the best cut-off for identifying pregnancies at high risk of adverse outcomes. In addition, data suggest that thyroid peroxidase autoantibody positivity and high or low concentrations of human chorionic gonadotropin seem to have a more prominent role in the interpretation of thyroid dysfunction than previously thought. Data on the effects of thyroid disease treatment are lacking, but some studies indicate that clinicians should be aware of the potential for overtreatment with levothyroxine. Here, we put studies from the past decade on reference ranges for TSH, determinants of thyroid dysfunction, risks of adverse outcomes and options for treatment into perspective. In addition, we provide an overview of the current views on thyroid physiology during pregnancy and discuss strategies to identify high-risk individuals who might benefit from levothyroxine treatment.

    This study was designed to clarify the efficacy of combination of thyroid hormone (euthyrox) therapy and percutaneous ethanol injection (PEI) in benign nodular thyroid diseases. 55 patients with benign nodular goiter after the first PEI session during the whole study period (from 3 till 12 months after PEI) daily received euthyrox in a dosage - 50 mkg. 48 women and 7 men with thyroid nodules of the various sizes, structures and echogenecity have been included in the study group. The control group consisted of 32 patients: 29 women and 3 men in the same age range as in the study group. In both groups PEI procedure was performed but in the control group no thyroid hormone was added. In patients who were receiving 50 mkg daily after 3 months of PEI progressive reduction of the nodule sizes was registered, the volume of a thyroid gland has decreased and approached to normal parameters (15,79+/-1,21 ml), and in 6-2 months the normal volume of the thyroid gland was registered. Thus, combination of thyroid hormone therapy and percutaneous ethanol injection (PEI) in treatment of patients with benign nodular goiter normalizes the size of a thyroid gland. Euthyrox is the additional factor causing reduction of thyroid nodules and constraining occurrence of new nodules in a thyroid gland.

    Surgery is the long-established therapeutic option for benign thyroid nodules, which steadily grow and become symptomatic. The cost of thyroid surgery, the risk of temporary or permanent complications, and the effect on quality of life, however, remain relevant concerns. Therefore, various...... and thermal ablation with laser or radiofrequency have been thoroughly evaluated, and are accessible procedures in specialized centres. In clinical practice, relapsing thyroid cysts are effectively managed with percutaneous ethanol injection treatment, which should be considered therapy of choice. In solid...... non-functioning thyroid nodules that grow or become symptomatic, trained operators may safely induce, with a single session of laser ablation treatment or radiofrequency ablation, a 50% volume decrease and, in parallel, improve local symptoms. In contrast, hyperfunctioning nodules remain best treated...

    The diagnostic value of the level of TSH receptor antibodies (TSHR-Ab) in the population of children with autoimmune thyroid diseases (AITDs) is still unknown. The aim of this cross-sectional study was to investigate the prevalence of TSHR-Ab in a paediatric cohort with AITD and healthy controls. A total of 240 serum samples were obtained from 205 patients with AITD, type 1 diabetes (T1D), juvenile arthritis (JA), and healthy controls (C). TSHR stimulating (TSI) and -blocking (TBI) immunoglobulins were measured in cell-based bioassays using CHO cells expressing a chimeric TSHR and a c-AMP response-element-dependent luciferase. TSI was reported as percentage of specimen-to-reference ratio (cutoff 140SRR%). Blocking activity was defined as percent inhibition of luciferase expression relative to induction with bovine TSH alone (40% inhibition). C as well as children with JA and T1D were both TSI and TBI negative. In contrast, children with Graves' disease (GD) were positive for TSI in 47/53 samples (88.7%) while those with thyroidal and orbital GD showed TSI positivity in 95.8% (23/24 samples). Serum TSI levels were SRR% 320 ± 157 and 417 ± 135 in GD and GD + orbitopathy, respectively (p = .02). Children with Hashimoto's thyroiditis (HT) were TSI positive in 4/83 (4.8%) samples, including two with orbital involvement. TSI levels were increased in HT children with vs. those without eye disease (SRR% 177 vs. 51, p TSI is prevalent in children with GD while the highest serum TSI levels were noted in children with AITD and orbitopathy.

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

    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).

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

    2008-01-01

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

    2012-10-15

    Purpose: To assess the clinical value of quantitative elastosonography compared with multiparametric ultrasound in differentiating the nature of thyroid nodules. Methods and materials: Ninety-seven consecutive patients (32 males, 65 females, mean age, 54 years, range 20–81 years) with thyroid nodules previously detected at color-Doppler ultrasound (CDUS), were prospectively examined with elastosonography with dedicated quantitative software (Elasto-Q, Toshiba) before surgery. Ultrasound examination and elastosonography were evaluated by two investigators in consensus. US features, color-Doppler pattern, and strain ratio value were evaluated. Sensitivity and specificity of CDUS and sono-elastography were compared using X{sup 2} test and ROC curves. Results: Sensitivity and specificity of hypoechogenicity, irregular margins or suspicious halo features, CDUS blood flow pattern, and strain ratio in the diagnosis of malignant nodules were 56.8%, 62.2%, 54.1% and 97.3% and 71.7%, 93.3%, 28.3%, and 91.7%, respectively. Elastosonography was more sensitive and specific than all ultrasonographic features in predicting malignancy of the thyroid nodules (p < 0.0001). According to elastosonographic features the lesions characterized by strain ratio ≥2 were highly likely to be of malignant nature (p < 0.0001, O.R. 396, 95%, CI: 44–3530). Conclusions: The results of the present study suggest that elastosonography with Q system is a valuable tool in the characterization of thyroid nodules and it seems to be far more accurate than CDUS. These findings as well as those of previous studies support its use in selecting patients who are candidates for surgery.

    Disparities in the management of patients with various medical conditions are well established. Colorectal diseases continue to remain one of the most common causes for surgical intervention. The aim of this study was to assess disparities (rural versus urban) in the surgical management of patients with noncancerous benign colorectal diseases. We hypothesized that there is no difference among rural versus urban centers (UC) in the surgical management for noncancerous benign colorectal diseases. The national estimates of surgical procedures for benign colorectal diseases from the National Inpatient Sample database 2011 representing 20 per cent of all in-patient admissions were abstracted. Patients undergoing procedures (abscess drainage, hemmoroidectomy, fistulectomy, and bowel resections) were included. Patients with colon cancer and those who underwent emergency surgery were excluded. The population was divided into two groups: urban and rural, based on the location of treatment. Outcome measures were in-hospital complications, mortality, and hospital costs. Subanalysis of UC was preformed: centers with colorectal surgeons and centers without colorectal surgeons. Regression analysis was performed. A total of 20,617 patients who underwent surgical intervention for benign colorectal diseases across 496 (urban: 342, rural: 154) centers, were included. Of the UC, 38.3 per cent centers had colorectal surgeons. Patients managed in UC had lower complication rate (7.6% vs 10.2%, P diseases managed surgically in urban versus rural centers. Specialized care with colorectal surgeons at UC helps reduce adverse patient outcomes. Steps to provide effective and safe surgical care in a cost-effective manner across rural as well as UC are warranted. Level III, retrospective cohort analysis.

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

    2000-01-01

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

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

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

    Full Text Available Increasing evidences indicate involvement of free radicals in the pathogenesis of benign and malignant breast diseases. Free radicals are highly reactive molecules and react with non–radicals in chain reaction leading to formation of new free radicals. If the defense mechanism of body fails to combat them, these free radicals pose a threat of injuring tissues by reacting with cell lipids. Lipids in the cell membrane undergo degradation to form hydroperoxides, which decompose to form a variety of products including malondialdehyde (MDA. MDA therefore was used as a marker to assess oxidative damage of cells and tissues. The aim of the present study was to assess the status of oxidative stress in the patients of benign and malignant breast diseases. Study has been made on the blood samples of 25 cases of benign breast disease and on an equal number of breast carcinoma patients. 20 healthy subjects were taken as the control cases.Mean MDA levels were significantly raised with depletion of antioxidant activity in all the patients in comparison to their control group suggesting the role of oxidative damage in the aetiopathogenesis of disease.

  5. Thyroid abnormalities after therapeutic external radiation

    1995-01-01

    The thyroid gland is the largest pure endocrine gland in the body and one of the organs most likely to produce clinically significant abnormalities after therapeutic external radiation. Radiation doses to the thyroid that exceed approximately 26 Gy frequently produce hypothyroidism, which may be clinically overt or subclinical, as manifested by increased serum thyrotropin and normal serum-free thyroxine concentrations. Pituitary or hypothalamic hypothyroidism may arise when the pituitary region receives doses exceeding 50 Gy with conventional, 1.8-2 Gy fractionation. Direct irradiation of the thyroid may increase the risk of Graves' disease or euthyroid Graves' opthalmopathy. Silent thyroiditis, cystic degeneration, benign adenoma, and thyroid cancer have been observed after therapeutically relevant doses of external radiation. Direct or incidental thyroid irradiation increases the risk for well-differentiated, papillary, and follicular thyroid cancer from 15- to 53-fold. Thyroid cancer risk is highest following radiation at a young age, decreases with increasing age at treatment, and increases with follow-up duration. The potentially prolonged latent period between radiation exposure and the development of thyroid dysfunction, thyroid nodularity, and thyroid cancer means that individuals who have received neck or pituitary irradiation require careful, periodic clinical and laboratory evaluation to avoid excess morbidity

    The emergent epidemic of metabolic syndrome and its complex list of sequelae mandate a more thorough understanding of benign prostatic hyperplasia and lower urinary tract symptoms (BPH/LUTS) in the context of systemic metabolic disease. Here we discuss the nature and origins of BPH, examine its role as a component of LUTS and review retrospective clinical studies that have drawn associations between BPH/LUTS and type II diabetes, inflammation and dyslipidemia. PPARγ signaling, which sits at the nexus of systemic metabolic disease and BPH/LUTS through its regulation of inflammation and insulin resistance is proposed as a candidate for molecular manipulation in regard to BPH/LUTS. Finally, we introduce new cell and animal models that are being used to study the consequences of obesity, diabetes and inflammation on benign prostatic growth. PMID:21645960

    Full Text Available Thyroid cancer represents approximately 0.5–1% of all human malignancy1. In the UK the incidence of thyroid cancer is 2-3 per 100,000 populations 2. In geographical areas of low iodine intake and in areas exposed to nuclear disasters the incidence of thyroid cancer is higher. Benign thyroid conditions are much more common. In the UK approximately 8 % of the population have nodular thyroid disease2. Nodular thyroid disease increases with age and is also more common in females and in geographical areas of low iodine intake. Primary thyroid malignancy can be broadly divided into 2 groups. The first group, which generally have much better prognosis, are the well-differentiated thyroid carcinoma, which includes papillary carcinoma, follicular carcinoma and Hürthle cell tumours. The second group includes the poorly differentiated thyroid carcinoma like medullary thyroid carcinoma and the anaplastic thyroid carcinoma. Other rare tumours such as sarcomas, lymphomas and the extremely rare primary squamous cell carcinoma of the thyroid should be included in the second group. Secondary or metastatic thyroid cancer can be from breast, lung, colon and kidney malignancies.

    We evaluate the feasibility of optical coherence tomography (OCT) and optical coherence microscopy (OCM) for imaging of benign and malignant thyroid lesions ex vivo using intrinsic optical contrast. 34 thyroid gland specimens are imaged from 17 patients, covering a spectrum of pathology ranging from normal thyroid to benign disease/neoplasms (multinodular colloid goiter, Hashimoto's thyroiditis, and follicular adenoma) and malignant thyroid tumors (papillary carcinoma and medullary carcinoma). Imaging is performed using an integrated OCT and OCM system, with thyroid tissues. With further development of needle-based imaging probes, OCT and OCM could be promising techniques to use for the screening of thyroid nodules and to improve the diagnostic specificity of fine needle aspiration evaluation.

    Carcinoembryonic antigen (CEA) was determined in the sera of 452 patients with benign liver diseases by radioimmunoassay (CEA-RIA Kit, Abbott). The CEA-level exceeded 2.5 ng/ml in 39 percent and 5.0 ng/ml in 9 percent of the cases. Independent influences of age, nicotin, and alcohol consumption and connective tissue proliferation of the liver on the CEA level were demonstrated and quantified by two- and higher-dimensional contingency table analysis. Toxic liver diseases were combined with elevated serum CEA values more often than inflammatory diseases. This aspect could not be investigated independently since there were only a few cases of toxic liver diseases without alcohol consumption. Sex and relative body weight do not seem to affect the CEA level. Additional diseases of the gastrointestinal tract or the cardiovascular system did not influence the serum CEA level in liver diseases. Therefore, in patients with benign liver diseases, an elevated serum CEA level indicates increased proliferation of the connective tissue. Age, nicotin, and alcohol consumption have to be considered independently in the clinical judgement of elevated serum CEA levels, irrespective of the underlying disease. (orig.) [de

    Full Text Available Abnormalities in the thyroid function and thyroid autoantibodies have been frequently described in patients with autoimmune diseases but seldom in antiphospholipid syndrome patients. In order to determine the prevalence of thyroid function and autoimmune abnormalities, we compared serum thyrotropin (TSH, serum free thyroxine (T4 levels, thyroid antithyroglobulin (TgAb and antithyroperoxidase (TPOAb levels of 25 patients with systemic sclerosis, 25 patients with rheumatoid arthritis and 13 patients with antiphospholipid syndrome to a control group of 113 healthy individuals.

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

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

    Conclusion: Although serum TSH screening is more sensitive for detecting thyroid abnormalities in children and adolescents with type1 diabetes, the presence of positive serum anti-TPO antibodies may be an earlier marker for thyroid disease, therefore, patients with positive antibodies should be monitored for serum TSH elevation at yearly intervals.

    A six-compartment model is proposed for the study of early iodine kinetics in the human thyroid gland including three compartments for extrathyroidal spaces. The results were compared with those obtained with an open two-compartment thyroidal model. In six euthyroid subjects the values of the unidirectional thyroid clearance and of the irreversible clearance were consistent with those generally accepted. With TSH stimulation a clear increase in the thyroidal pump effectiveness was found without an increase in the irreversible clearance. In four untreated thyrotoxic patients a tenfold increase in the unidirectional thyroid clearance was found. The unidirectional clearance remained elevated in seven patients after Carbimazole treatment and the binding rates were reduced. The six-compartment model demonstrated a rapid exit from the bound iodine compartment. In three of four goitrous patients studied, the thyroid unidirectional clearance was significantly increased. The volumes of the iodide compartments were much higher than those observed in the other groups. The method was applied to analyse the kinetics of different parts of the thyroid. (orig./MG)

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

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

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

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

    This course considers the group of bladder and kidney diseases that poses great difficulty in preoperative diagnosis. Transitional cell and hypernephroma look-alikes are the true ''great imitators'' of diseases of the urinary system. The first half of the course examines the pathologic-physiologic underpinnings of granulomatous diseases of the urinary tract. With an understanding of these basic processes, the myriad radiologic manifestations of this group of diseases (tuberculosis, xanthogranulomatous pyelonephritis, malakoplakia, schistosomiasis, and so forth) will become more obvious. The second part of the course examines the radiologic and pathologic manifestations of certain common forms of cystitis (cystitis cystica, cystitis glandularis, Cytoxan cystitis, cystitis emphysematosa) and other benign processes (pheochromocytomas, neurofibromas, fibrous polyps, duplications) that may be confused with their malignant counterparts by the unsuspecting radiologists. Knowledge of these two large groups of disease should allow a more intelligent approach to these often misdiagnosed urinary tract diseases

    Swelling of the thyroid gland is a common symptom in patients with Graves' disease. However, until recently there were no adequate means of measuring the thyroid volume. In this study, thyroid volume (in Graves' disease patients on antithyroid drug (ATD) therapy) was measured serially by a new ultrasound technique involving the use of a specifically programmed computer. The relationships between thyroid volume and prognosis, and between thyroid volume and serum thyroglobulin (Tg) concentration were examined. Sixty untreated patients with Graves' disease and 62 healthy subjects were included in the study. Twenty of the 60 patients with Graves' disease who had no anti-Tg antibodies underwent serial measurement of thyroid volume and serum Tg concentration during long term (18-42 months) ATD therapy. Thyroid volume in normal subjects ranged from 5.6 ml to 20.2 ml, with a mean of 12.0 +/- 4.0 ml. In patients with untreated Graves' disease, the volume ranged from 13.3 to 190.7 ml with a mean of 40.2 +/- 27.8 ml (n = 60). Thyroid volume was significantly correlated with both serum Tg concentration (n = 20, r = 0.678, p less than 0.01) and serum TSH receptor antibody activity (n = 18, r = 0.590, p less than 0.01). During ATD therapy, the thyroid volume decreased gradually in most patients. Eleven of 20 treated patients experienced remission after therapy was discontinued, and in these patients, thyroid volume was significantly smaller (p less than 0.01) than before treatment. Four patients developed hypothyroidism due to over dosage of ATD at which time thyroid volume increased in all four. In the course of therapy, even during episodes of hypothyroidism changes in serum Tg concentrations paralleled changes in thyroid volume. After 12 months of therapy, thyroid volume expressed as a percentage of the pretreatment value was significantly smaller in patients in remission (77.6 +/- 8.9%) than in those who did not show remission (92.4 +/- 11.6%). These data suggest that serial

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

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

    In the paper authors have analyzed 70 cases of different neck, throat and larynx tumors connected with thyroid gland (44 female and 26 male, age 14 to 78), treated surgically in ENT Department of Country Hospital No 1 in Rzesów from 1974 to 1994. The material consists of 35 (50%) patients with neck tumors of thyroid origin, 20 (28,6%) patients with the tumor of thyroid gland or with nodular goitre, 8 (11,4%) patients with advanced cancer of the thyroid with shortness of breath and 7 (10%) patients with ectopy or splitted of thyroid. Based on the histopathological examination it was revealed that the highest group consists of patients with thyroid cancer because all of them live in the south-east part of Poland, which is known to be the area of higher risk of thyroid cancer. Neck tumor was the first symptom of thyroid disease in half of patients from the group mentioned above and the first symptom of 57,5% of patients with malignant neoplasms of thyroid gland were metastases to the neck lymph nodes. Among patients with thyroid malignant neoplasm the male:female ratio was 1:1,35, and the mean age-53,5 years was about 10 years higher than in the rest of patients. In 7 patients with thyroid cancer effective radical surgical treatment was applied. In 5 cases surgical treatment exceeded thyroid gland. It required very careful dissection and identification of recurrent laryngeal nerves and parathyroid glands to avoid iatrogenic damage.

    To evaluate the sonographic findings of Hashimoto's thyroiditis and associated nodular lesions. We retrospectively reviewed the sonographic findings of twenty patients who had surgically confirmed Hashimoto's thyroiditis between 1 March 2005, and 26 November 2005. In these patients, we reviewed the sonographic findings of the associated focal nodular lesion. Assessed were size, homogeneity, and echogenicity of the diseased thyroid gland and shape, echogenicity, margin, rim, microcal cification of the associated nodules. Without knowledge of the pathological diagnosis of the nodular lesions, based on the sonographic criteria, the nodules were classified as either malignant or benign. Hashimoto's thyroiditis demonstrates a variety of sonographic findings for size, homogeneity, and echogenicity. Among the nineteen nodules that were sonographically diagnosed and pathologically confirmed, nine papillary cancers, seven nodular hyperplasias, two Huthle cell adenomas, and one focal hyalinized fibrosing nodule were included. All of the nine papillary cancers showed more than one malignant finding such as marked hypoechogenicity, an irregular shape, a taller than wide shape, a spiculated margin, or microcalcifications that were classified as malignant nodulea, and all of the ten benign nodules showed no malignant findings. Circumscribed isoechoic, hyperechoic, or hypoechoic nodules without calcification were classified as bending nodules. Hashimoto's thyroiditis demonstrates various findings on a sonographic examination,and associated various benign and malignant lesions. Moreover, a sonographic examination is helpful to differentiate between malignant and benign lesions in Hashimoto's thyroiditis as in the normal thyroid

    Thyroid autoimmunity is a major risk factor for gestational thyroid disease, and recently various other risk factors have been identified, including maternal age, body mass index (BMI) and parity. Human chorionic gonadotropin (hCG) is an important determinant of gestational thyroid function, yet it is unknown to what extent differences in hCG concentration affect the risk for thyroid disease. We have recently shown that thyroperoxidase antibody positivity impairs the thyroidal response to hCG stimulation, which may suggest that this is a mechanism through which thyroid autoimmunity acts as a risk factor for thyroid disease. The purpose of this study is to determine whether hCG is a risk factor for thyroid disease entities and whether recently identified risk factors for thyroid disease may influence the thyroidal response to hCG stimulation. Human chorionic gonadotropin, thyrotropin (TSH), and free thyroxine (FT4) were measured in 5435 pregnant women participating in a prospective cohort. The association of hCG with thyroid disease entities, and the association of known risk factors with thyroidal response to hCG stimulation were studied using multivariable linear regression models. Higher hCG concentrations were associated with a higher risk of subclinical and overt hyperthyroidism. Lower hCG concentrations were associated with a higher risk of hypothyroxinemia. In contrast, hCG concentrations were not associated with subclinical hypothyroidism. Further analyses showed that in women with hypothyroxinemia, high hCG concentrations still suppressed TSH. However, in women with subclinical hypothyroidism, high hCG concentrations were not associated with higher FT4. Higher BMI, male fetal sex, and maternal parity >2 were associated with a lower thyroidal response to hCG stimulation. Human chorionic gonadotropin is associated with the risk of (subclinical) hyperthyroidism and hypothyroxinemia, but not with the risk of (subclinical) hypothyroidism. Women with

    Context: Nodular thyroid disease is very common. Most nodules are asymptomatic, are benign by fine-needle aspiration, remain stable, and can be followed by observation alone in the majority of the patients. Occasionally, nodules grow or cause symptoms requiring treatment. So far, surgery has been...... our main option for treatment. Objective: In this review, we discuss nonsurgical, minimally invasive approaches for small thyroid masses, including indications, efficacy, side effects, and costs. Evidence Acquisition: We selected recent publications related to minimally invasive thyroid techniques...... therapy is recommended for recurrent benign thyroid cysts. Either ultrasound-guided laser or radiofrequency ablation can be used for symptomatic solid nodules with normal or abnormal thyroid function. Microwave ablation and high-intensity focused ultrasound are newer approaches that need further clinical...

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

    Autoimmune thyroid diseases (ATD), and pernicious anemia (PA) in particular, are common in elderly people. The relationship between both of these is currently being discussed. The objective of this study is to determine the correlation between ATD and PA in elderly people, and if there are other associated factors affecting this relationship. The factors studied to analyse this association were social-health variables, autoimmune comorbidity (type 1 diabetes and other autoimmune diseases), the taking of drugs that alter vitamin B12 levels (Metformin and protein bomb inhibitors), and the chronological order in which both diseases appear in this population. A logistic regression analysis was performed to determine which of the described variables could have an on both diseases. The prevalence was 8.2% for ATD and 3.3% for PA, with a progressive increase in the annual incidence in the past 10 years from 7.1 to 12.7 cases per 1,000 persons>65 years for ATI, and from 1.6 to 7.4 cases for PA. PA was found in 18.6% of the patients with ATD, and the 45% of PA presented with ATD, mainly in women (RR=6.0). The average time in diagnosing the second disease was about 8 years. When there was a third autoimmune disease the likelihood of ATD and PA increased fourfold. Patients with ATD and consuming drugs which were affecting the absorption of vitamin B12 had double the probability of developing a PA compared with those who were not taking medications. The results of this study confirm the association between ATI and AP among people 65 or older, also a progressive increase in the incidence of these diseases. Copyright © 2014 SEGG.

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

    Celiac disease may be associated with other underlying autoimmune diseases. Among these, thyroid disease has been described in around 10% of the cases with hypothyroidism being the most frequently reported. Clinical suspicion of thyroid involvement in patients with celiac disease is difficult since the symptomatology is scarce or is masked by the picture of malabsorption. Nonetheless, its detection is important since it is not solved by gluten free diet and its correction requires specific treatment. Thyroid function studies, in addition to determination of antithyroglobulin and antimicrosomal antibodies, should be considered in celiac patients refractory to conventional dietetic treatment. We herein present the case of a 65-year-old woman who consulted for a malabsorption syndrome in whom celiac disease of the adult was simultaneously presented with hyperthyroidism secondary to autoimmune thyroiditis.

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

    Ovarian cancer is the seventh most common cancer in women and the most frequent cause of gynaecological malignancy-related mortality in women. Currently, no standardized reliable screening test exists. MicroRNA profiling has allowed the identification of signatures associated with diagnosis, prognosis and response to treatment of human tumours. The aim of this study was to determine if a microRNA signature could distinguish between malignant and benign ovarian disease. A training set of 5 serous ovarian carcinomas and 5 benign serous cystadenomas were selected for the initial experiments. The validation set included 20 serous ovarian carcinomas and 20 benign serous cystadenomas. The serum\\/plasma focus microRNA Exiqon panel was used for the training set. For the validation set a pick and mix Exiqon panel, which focuses on microRNAs of interest was used. A panel of 4 microRNAs (let-7i-5p, miR-122, miR-152-5p and miR-25-3p) was significantly down regulated in cancer patients. These microRNAs target WNT signalling, AKT\\/mTOR and TLR-4\\/MyD88, which have previously been found to play a role in ovarian carcinogenesis and chemoresistance. let-7i-5p, miR-122, miR-152-5p and miR-25-3p could act as diagnostic biomarkers in ovarian cancer.

    To investigate the mRNA expressions of RASSF1A, Galectin-3 and TPO in papillary thyroid carcinoma and some other thyroid benign lesions, and evaluate their diagnostic significance. Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the mRNA expression of RASSF1A, galectin-3 and TPO in the samples from 73 cases, including 23 cases with papillary thyroid cancer, 16 with nodular goiter, 29 with thyroid adenoma and 5 with Hashimoto's disease. A statistically significant difference in the mRNA expression of RASSF1A, Galectin-3 and TPO was observed between papillary thyroid carcinoma and follicular benign lesions (P0.05). A negative correlation of the expression of RASSF1A and Galectin-3 mRNA was found between thyroid benign lesions and malignant ones (P = 0.000). While the mRNA expression of RASSF1A and TPO was positively correlated between benign and malignant lesions (P = 0.028). Loss of expression of RASSF1A and TPO mRNA but high expression of Galectin-3 mRNA in papillary thyroid carcinoma are common. Therefore, the products of these three genes may be closely related to the development of thyroid papillary carcinoma, and may be used as useful markers in differential diagnosis of papillary thyroid carcinoma from the benign lesions. The results are more reliable if this detection method is used in combination with other techniques.

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

    2008-06-01

    Full Text Available Postsurgical hypothyroidism and its incidence has not been fully investigated. In this study, the incidence of hypothyroidism and its possible risk factors at Shariati Hospital was assessed. One hundred and two patients with benign thyroid diseases, who had undergone thyroidectomy, were investigated with regards to thyroid function profile during period of one year after the operation every three months with post-operative sample as the baseline. Hypothyroidism was developed in 36 patients (35.2% on average 5 ± 3.2 months after surgery. Factors such as increased age, operation type, histopathologic type, underlying disease, lymphocytic infiltration and use of levothyroxine before surgery were associated with the increased incidence of hypothyroidism. It seems that use of indicators such as Graves' disease and lymphocytic infiltration in pathologic specimens should be helpful in projecting the potential occurrence of hypothyroidism in patients undergoing thyroidectomy.

    Background and Objectives Although there was growing evidence supporting the hypothesis that Notch1 was one of the few candidate genes linked with colorectal cancer (CRC) susceptibility, the precise level of Notch1 protein expression in benign and malignant colorectal diseases was still unknown. Our study has investigated the Notch1 expression in benign and malignant colorectal diseases as well as to investigate the role and clinicopathological significance of aberrant expression of Notch1 in CRC. Methods The protein expression of Notch1 was examined by immunohistochemistry in 901 clinical specimens with colorectal diseases, including 220 patients with ulcerative colitis, 232 patients with colorectal adenoma and 449 patients with colorectal cancer. Associations between the expression of Notch1 and various clinicopathological features, as well as survival status, were studied. Results Cytoplasmic Notch1 was expressed in 7.7% of patients with ulcerative colitis, 14.7% of patients with colorectal adenoma and 58.0% of patients with colorectal cancer, respectively. Colorectal cancer patients with high expression levels of Notch1 showed lower overall survival (OS) and disease-free survival (DFS) rates than those patients with low Notch1 expression. Conclusions Expression level of Notch1 was gradually increased from precancerous lesions to cancer. It might play as an oncogene in the CRC development, and might be potentially used as a biomarker for prognosis of CRCs. PMID:24312514

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

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

    The purpose of this study was to investigate the usefulness of the ultrasonography as a screening test for thyroid diseases. For 7 months, thyroid ultrasonography (7.5 MHz linear array) was performed prospectively by radiologists on 1,316 subjects who do not have a history of the thyroid disease. We analyzed the morphological abnormalities of thyroid gland and these were classified as the nodulal, cystic and diffuse types in accordance with the gender and ages of the patients. We performed ultrasound-guided fine needle aspiration in 21 patients who had sonographic features that were suggestive of malignant thyroid nodules. Physical examination was performed for all subjects by clinicians before the thyroid ultrasonography, and we compared the detectability of thyroid lesions between ultrasonography and physical examination. Thyroidal abnormalities were detected in 94 (7.1%) of 1,316 subjects. Among the 94 patients, 72(5.5%) showed as nodules, 18 (1.4%) showed as cysts and 4 (0.3%) showed as diffuse abnormalities. The result of the ultrasound-guided aspiration on 21 patients showed 4 malignant nodules, 16 benign nodules and 1 undetermined nodule. Physical examination detected abnormalities in only 12 patients (12.8%) of the 94 patients, which were showed as nodules, cysts and the diffuse type by ultrasonography. Thyroid disease of the general population was relatively common and the detection rate with performing physical examination for the thyroid nodule, cyst and the diffuse type was lower than that for ultrasonography. Thyroid ultrasonography is a useful screening modality for detecting thyroid diseases

    Recently, Imanishi et al have developed new CT software for quantitative in vivo measurement of thyroid iodine. Using a CT system with the software, we measured volume, iodine concentration and total iodine content of thyroids in 63 controls and 435 patients with various diffuse thyroid diseases and thyroid nodules. In controls, all of them showed no difference between the sexes. Although the iodine concentration of the thyroid showed no difference among children, adults and seniles, the volume and total iodine content of the thyroid appeared smaller in children and seniles than in adults. In addition, although the volume and iodine concentration of the thyroid had two peaks in distribution, the total iodine content had almost normal distribution. Normal range of volume, iodine concentration and total iodine content in adults were 5.2-15.5 cm 3 , 0.28831-0.85919 mg/cm 3 and 2.35-11.69 mg, respectively. In thyroid nodule, there is no significant difference in volume, iodine concentration and total iodine content between benign and malignant nodules. All nodules with iodine concentration of less than 0.00007 mg/cm 3 were benign. No thyroid was higher in iodine concentration than the normal range although the thyroid was lower in 78.7% of patients with diffuse thyroid diseases. In all thyroids with increasing iodine concentration and total iodine content in medication course, thyroidal symptoms and signs were uncontrollable by the medication. In 43.8% of patients with long-period systemic diseases, the thyroid showed abnormality in any of the three. We concluded that quantitative in vivo measurement of thyroid iodine by CT could assist the diagnosis of thyroid diseases and decision of therapeutic methods. (author)

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

    Background: Like stable iodine, radioiodines concentrate in the thyroid gland, increasing thyroid cancer risk in exposed children. Data on exposure to the embryonic/fetal thyroid are rare, raising questions about use of iodine 131 (I-131) in pregnant women. We present here estimated risks of thyroid disease from exposure in utero to I-131 fallout from the Chernobyl nuclear accident. Methods: We conducted a cross-sectional thyroid screening study (palpation, ultrasound, thyroid hormones, and, if indicated, fine needle aspiration) from 2003 to 2006. Participants were 2582 mother-child pairs from Ukraine in which the mother had been pregnant at the time of the accident on April 26, 1986, or 2 months after the time during which I-131 fallout was still present (1494 from contaminated areas, 1088 in the comparison group). Individual cumulative in utero thyroid dose estimates were derived from estimated I-131 activity in the mother’s thyroid (mean 72 mGy; range 0–3230 mGy). Results: There were seven cases of thyroid carcinoma and one case of Hurthle cell neoplasm identified as a result of the screening. Whereas the estimated excess odds ratio per gray for thyroid carcinoma was elevated (excess odds ratio per gray 11.66), it was not statistically significant (P = 0.12). No radiation risks were identified for other thyroid diseases. Conclusion: Our results suggest that in utero exposure to radioiodines may have increased the risk of thyroid carcinoma approximately 20 yr after the Chernobyl accident, supporting a conservative approach to medical uses of I-131 during pregnancy.

    Benign tremulous parkinsonism (BTP) is characterized by a prominent tremor that occurs both at rest and with action in conjunction with other mild features of parkinsonism. The progression of symptoms is typically slow and there is often a positive family history. Although BTP is included within the phenotypic spectrum of Parkinsonism its exact relationship with idiopathic Parkinson's disease remains unclear. Treatment of BTP is challenging especially considering the poor response to levodopa, therefore surgical therapies such as deep brain stimulation surgery are sought for treatment of these tremors. In this review, we will summarize the clinical features, diagnosis, neuropathology and treatment for BTP.

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

    Whether thyroidectomy for metastases to the thyroid is associated with a survival benefit remains debatable; in general, palliation and disease control are accepted goals in this setting. We evaluated the clinical features and overall survival of patients with thyroid metastasis treated by thyroid resection or nonoperatively. This retrospective analysis included 90 patients identified with metastasis to the thyroid confirmed pathologically via thyroidectomy (n = 31) or fine-needle aspiration biopsy (n = 59). Overall survival was calculated by the Kaplan-Meier method, and differences between groups were calculated by Pearson's χ (2) coefficient. The most common primary malignancies were renal cell (20%), head and neck (19%), and lung (18%). The median time from primary tumor diagnosis to thyroid metastasis diagnosis was 37.4 months (range 0-210 months). Most metastases (69%) were metachronous, and 12% were isolated. The median follow-up after diagnosis of thyroid metastasis was 11.5 months (range 0-112 months). Median overall survival was longer in thyroidectomy patients compared to the fine-needle aspiration group (34 vs. 11 months, P renal cell primary tumors were more likely to undergo thyroidectomy than patients with other primary tumors (78 vs. 24%, P thyroid metastasis diagnosis, and thyroidectomy was only offered to three patients. Thyroidectomy was safe for selected patients with metastatic disease to the thyroid. Patients with metachronous or renal cell metastasis to the thyroid and whose primary tumor is/was treatable may be appropriate candidates for resection. Lung cancer metastasis to the thyroid is generally an ominous sign.

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

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

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

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

    Background: Radiotherapy of benign diseases is controversial and rarely applied in Anglo-American countries, whereas in other parts of the world it is commonly practiced for several benign disorders. Similar to a European survey, a pattern of care study was conducted in Germany. Method: Using a mailed questionnaire, radiation equipment, treatment indication, number of patients, and treatment concepts were assessed in 1994, 1995, and 1996 in 134 of 152 German institutions (88%): 22 in East and 112 in West Germany; 30 in university hospitals and 104 in community hospitals. Average numbers of each institution and of all institutions were analyzed for frequencies and ratios between regions and among institutions. Radiation treatment concepts were analyzed. Results: A mean of 2 (range 1-7) megavoltage and 1.4 (range 0-4) orthovoltage units were available per institution; 32 institutions (24%) had no orthovoltage equipment. A mean of 20,082 patients were treated annually: 456 (2%) for inflammatory diseases (221 hidradenitis, 78 local infection, 23 parotitis; 134 not specified) 12,600 (63%) for degenerative diseases (2711 peritendinitis humeroscapularis, 1555 epicondylitis humeri; 1382 plantar/dorsal heel spur; 2434 degenerative osteoarthritis; 4518 not specified); 927 (5%) for hyperproliferative diseases (146 Dupuytren's contracture, 382 keloids; 155 Peyronie's disease; 244 not specified); 1210 (6%) for functional disorders (853 Graves' orbitopathy; 357 not specified); and 4889 (24%) for other disorders (e.g., 3680 heterotopic ossification prophylaxis). In univariate analysis, there were geographic (West vs. East Germany) differences in using radiation therapy (RT) for inflammatory and degenerative disorders, and institutional differences (university versus community hospitals) in using RT for hyperproliferative and functional disorders (p < 0.05). The prescribed dose concepts were mostly in the low dose range, <10 Gy but varied widely and inconsistently within

    PurposeThere have been few case reports describing cystic duct stent insertion in the management of acute cholecystitis secondary to benign disease with no case series published to date. We present our series demonstrating the role of cystic duct stents in managing benign gallbladder disease in those patients unfit for surgery.Materials and MethodsThirty three patients unfit for surgery in our institution underwent cystic duct stent insertion for the management of acute cholecystitis in the period June 2008 to June 2013. Patients underwent a mixture of transperitoneal and transhepatic gallbladder puncture. The cystic duct was cannulated with a hydrophilic guidewire which was subsequently passed through the common bile duct and into the duodenum. An 8Fr 12-cm double-pigtail stent was placed with the distal end lying within the duodenum and the proximal end within the gallbladder.ResultsTen patients presented with gallbladder perforation, 21 patients with acute cholecystitis, 1 with acute cholangitis and 1 with necrotising pancreatitis. The technical success rate was 91 %. We experienced a 13 % complication rate with 3 % mortality rate at 30 days.ConclusionCystic duct stent insertion can be successfully used to manage acute cholecystitis, gallbladder empyema or gallbladder perforations in those unfit for surgery and should be considered alongside external gallbladder drainage as a definitive mid-term treatment option.

    Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

    Full Text Available Objective: To assess and compare the risk factors in patients with benign gastric and duodenal ulcers and to correlate the prevalence of Helicobacter pylori (H. pylori infection in benign peptic ulcer disease. Methods: A total of 30 consecutive patients with peptic ulcer disease were included in this study after upper gastrointestinal endoscopy. Their clinical profile and endoscopic findings were noted. Antral biopsies were subjected to histopathological examination and urease test for detection of H. pylori. Results were correlated. The study was cleared by the Institute Research Council and the Ethics committee. Results: The male: female ratio was 11:4. Overall, H. pylori infection was prevalent in 93.3% of the patients. Patients who took spicy food had a significantly higher rate of H. pylori positivity (P=0.04. Smoking, alcohol intake and NSAIDs did not affect H. pylori status in patients. There was no significant association between the site of the ulcer and H. pylori infection. Conclusions: Based on our observations we conclude that prevalence of H. pylori infection is similar in duodenal and gastric ulcers and intake of spicy food is a significant risk factor.

    A comparison is made on the possibilities of the radioistope and radioimmunoassay methods for thyroid gland disgnosis. Radioimmunoassay allows to define practically every hormone from the pituitary-thyroid gland axis. The clinical significance of the routine tests for thyroxine, triiodothyrodine, thyroid stimulating hormone (STH), reverse-T 3 and thyroglobulin is investigated on 1500 patients. A precise method is described for determination of free concentrations of thyroxine and triiodothyronine. A new sensitive test for STH was developed by the authors using monoclonal antibodies binding the antigens in blood serum in 'sandwich' mode. The test is suitable when STH is of lower level due to hypothyroidism. For hyperthyroidism diagnosis the amount of triiodothyronine and the index of free thyroxine is used. It is concluded that the best diagnostic techniques of thyroid disfunction is the radioimmunoassay

  7. Feline focus: Diagnostic testing for feline thyroid disease: hypothyroidism.

    Although naturally occurring hypothyroidism is very rare in cats, iatrogenic hypothyroidism is a recognized complication of treatment for hyperthyroidism. However, confirming the diagnosis of hypothyroidism in cats is not generally straightforward. The potential for false-negative and false-positive results exists with all thyroid function tests, especially in older cats that may have concurrent nonthyroidal illness. Therefore, all thyroid function test results must be interpreted in light of the cat's history, clinical signs, and other laboratory findings. If a low to low-normal serum thyroxine (T4) value is found in a cat that has been treated for hyperthyroidism, repeating the total T4 analysis, determining free T4 and thyroid stimulating hormone (TSH) concentrations, or performing a TSH stimulation test or thyroid scintigraphy may be needed to confirm the diagnosis.

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

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

    Background: Autoimmune thyroid diseases (ATDs) are the most common endocrine diseases which result in rheumatologic manifestations. Some studies have shown association between rheumatologic disorders and ATDs. Thus, the aim of this study was to assess the frequency of rheumatologic manifestations in patients with ATDs. Materials and Methods: In this cross-sectional descriptive study during 2010 to 2011, 65 patients with ATDs referred to the Rheumatology clinic of 5 Azar Hospital in Gorgan (North of Iran) were studied via systematic random sampling and patients with positive antithyroid peroxides (anti-TPO) were included in the study. These patients were examined by a rheumatologist for diagnosis of rheumatologic manifestations and tested for serum levels of TSH, Free T3 and T4, Anti-Nuclear Antibodies (ANAs) and Rheumatoid Factor (RF). SPSS software (version 16) and descriptive statistics were used for data analysis. Results: Nine males (14.8%) and 56 females (86.2%) with mean age of 38.81±1.44 years were studied. Overall, Rheumatologic manifestations were seen in 86.2 % (n=56). In this study, the most frequent rheumatologic manifestations were Carpal Tunnel Syndrome (36.1%) and Osteoarthritis (23%). Reynaud’s phenomenon (RP) (10.7%), Discopathy (8.9%), Fibromyalgia (5.3%), Myopathy (3.6%), Rheumatoid arthritis (3.6%) and trigger finger (3.6%) were other manifestations, respectively. Conclusion: In this region, there is a high frequency of rheumatologic manifestations in patients with ATDs. Thus, initial evaluation and regular checkings are recommended. PMID:25478383

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

    The aims of the study were (i) to investigate the prevalence of overt and subclinical thyroid disease in HIV-positive patients in a London teaching hospital; (ii) to determine risk factors associated with the development of thyroid dysfunction, including highly active antiretroviral therapy (HAART) and individual antivirals, and (iii) to determine the occurrence of thyroid dysfunction longitudinally over 3 years. The study consisted of retrospective analyses of thyroid function tests (TFT) in HIV-positive patients. The period prevalence of and factors associated with clinical and subclinical thyroid dysfunction were investigated. Patients with normal TFT but previous thyroid disease were identified from pharmacy records and included in the overt category. A total of 1565 patients (73% of the clinic population) had at least one TFT taken since 2001. Overall, 3584 samples were analysed. Of the patients included in the study, 1233 (79%) were male, 1043 (66%) were white and 365 (23%) were black African, and in 969 (62%) the main risk for HIV was homosexual sex. Median age at baseline was 37 years. Nine hundred patients (58%) were on HAART at the start of the study. Thirty-nine (2.5%) were found to have overt hypothyroidism, and eight (illness. A normal TFT was obtained for 1118 patients (75.5%). Multivariate analysis suggested that no independent variables were significantly associated with overt hypothyroidism, including HAART and stavudine use specifically. Repeated measurements over 3 years were available for 825 patients and only eight new cases (1%) of overt thyroid disease occurred. The prevalence of overt thyroid disease was low in this cohort, suggesting that screening is not warranted.

    2012-01-01

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

    Thyroid-stimulating hormone (TSH) and thyroxine (T/sub 4/) were measured in sera from 214 patients with Hodgkin's disease. The literature was reviewed for patients with lymphoma or head and neck carcinoma who had received prior radiation therapy that encompassed the thyroid. Among 169 patients who had been treated with mantle radiation therapy at our center, 112 (66%) had evidence of thyroid dysfunction, including 43 with depressed T/sub 4/ levels. Among 45 who did not receive mantle irradiation, only three had evidence of dysfunction and none of these had T/sub 4/ depression. Thyroid dysfunction developed slowly, with less than 15% of patients tested during the first year showing dysfunction and the maximum of 66% reached at about 6 years. This entity is very common in lymphoma patients yet often is overlooked except in instances of specific thyroid function evaluation for research. A substantial proportion of patients with head and neck carcinoma develops thyroid dysfunction after irradiation, especially if therapy includes hemithyroidectomy. Serum TSH measurement every 6 months for at least 5 to 6 years after irradiation will detect early thyroid dysfunction. All patients with elevated serum TSH should be treated with sodium levothyroxine, regardless of whether they are clinically hypothyroid.

    Objective: This study was conducted to observe the optimal results of long term treatment with antithyroid drugs in patients with graves' disease. Methodology: Total of 268 patients with graves' disease who were referred to endocrinology clinic during 2005 - 2008 and treated with anti-thyroid drugs for a long term were studied. Data about the age, gender, estimated weight of thyroid before and after the treatment, level of thyroid hormones, disease relapse, hypothyroidism and the drug side-effects were collected and analyzed. Results: Eighty two (31%) patients were males, 186 (69%) females, mean age of 35 +- 27 years and follow-up course of 31+- 16 months], were studied. After the discontinuation of long term treatment, 53% were affected with relapse of hyperthyroidism. The mean duration of hyperthyroidism relapse after the treatment was 8.3 +- 7.3 months. The relapse rate was and patients with large thyroid and lower TSH level at the end of treatment, the rate of relapse treatment was about 6%. More decrease of thyroid size during the treatment course, higher level of serum TSH after discontinuation of the treatment, and lower thyroid hormone levels before the treatment were some of the effective factors in hypothyroidism incidence (P=0.005, patients (39%) remained euthyroid in the follow-up course. Conclusion: patients with graves' especially in middle-aged women with smaller goiters. (author)

    The aim was to determine the efficacy, safety, and long-term clinical and functional results of coloanal anastomosis in patients with complicated benign and malignant rectal disease. Twenty-nine patients underwent coloanal or colopouch-anal anastomosis for either carcinoma of the rectum not technically amenable to conventional low anterior resection, severe radiation injury, large benign lower third tumors, or complications of previous operations. The mean age of the patients was 61 years and 82% were men. A diverting colostomy was constructed in 55% of the patients. The mean (+/- SEM) length of follow-up was 20 +/- 3 months. There was no operative mortality. Transient urinary retention, however, occurred in 40%, anastomotic stricture in 28%, and anastomotic leakage in 3.4%. Four patients (14%) could not have intestinal continuity restored and therefore were considered failures. The stool frequency for all remaining patients (N = 25) was 3 +/- 1 per day (mean +/- SEM) and did not vary with age, sex, or indication for operation. Complete continence was achieved by 84% of patients, but no patient was incapacitated by poor bowel function. In patients in whom a conventional colorectostomy is impractical or unwise, coloanal anastomosis is a safe and efficacious alternative operation that preserves anal continence.

    Full Text Available Photodynamic therapy (PDT uses a photosensitizer, light energy, and molecular oxygen to cause cell damage. Cells exposed to the photosensitizer are susceptible to destruction upon light absorption because excitation of the photosensitizing agents leads to the production of reactive oxygen species and, subsequently, direct cytotoxicity. Using the intrinsic cellular heme biosynthetic pathway, topical PDT selectively targets abnormal cells, while preserving normal surrounding tissues. This selective cytotoxic effect is the basis for the use of PDT in antitumor treatment. Clinically, PDT is a widely used therapeutic regimen for oncologic skin conditions such as actinic keratosis, squamous cell carcinoma in situ, and basal cell carcinoma. PDT has been shown, under certain circumstances, to stimulate the immune system and produce antibacterial, and/or regenerative effects while protecting cell viability. Thus, it may be useful for treating benign skin conditions. An increasing number of studies support the idea that PDT may be effective for treating acne vulgaris and several other inflammatory/infective skin diseases, including psoriasis, rosacea, viral warts, and aging-related changes. This review provides an overview of the clinical investigations of PDT and discusses each of the essential aspects of the sequence: its mechanism of action, common photosensitizers, light sources, and clinical applications in dermatology. Of the numerous clinical trials of PDT in dermatology, this review focuses on those studies that have reported remarkable therapeutic benefits following topical PDT for benign skin conditions such as acne vulgaris, viral warts, and photorejuvenation without causing severe side effects.

  6. Hashimoto thyroiditis: clinical and diagnostic criteria.

    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. Copyright © 2014 Elsevier B.V. All rights reserved.

    To evaluate whether women during early pregnancy with "hypothyroidism" symptoms are at risk of biochemically defined hypothyroidism. The 2017 Guidelines of the American Thyroid Association (ATA) recommend case-finding on the basis of symptoms to identify these women during pregnancy, while evidence is lacking. Construct validation of a thyroid hypofunction symptom checklist during the first trimester of pregnancy comparing high scores with biochemically defined hypothyroidism. A total of 2198 healthy pregnant women from an iodine-sufficient area in 2013-2014. Completion of a draft questionnaire with "classical" symptoms of hypothyroidism at 12 weeks of gestation. The 2.5th and 97.5th percentiles of TSH and fT4 during pregnancy in TPO-Ab-negative (symptom scores and those with low symptom scores. According to fT4 and TSH cut-offs (0.23-4.0 mIU/L and 11.5-18.0 pmol/L, respectively), there were 15 women with "to treat hypofunction" (overt hypothyroidism or TSH >10 mIU/L) and 68 women with subclinical hypothyroidism. Questionnaire construct validation revealed a 12-item hypothyroid checklist with normally distributed scores. The cut-off indicating high scores of OH was set at 1 SD > mean. Women with high symptom scores did not present more often with biochemically defined thyroid hypofunction. This study does not support the ATA recommendation that pregnant women who require levothyroxine therapy can be identified by case-based screening of women with symptoms of thyroid disease. © 2017 John Wiley & Sons Ltd.

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

    Full Text Available Summary Introduction: Sexual dysfunction is highly prevalent, affecting 40% of the female population. The incidence of such dysfunction is known to be higher among women with malignant breast disease and in patients with depression or anxiety. However, there are few data regarding the prevalence of sexual dysfunction among women with benign breast disease (BBD. Objective: To evaluate the incidence of sexual dysfunction, depression and anxiety among women with BBD, in comparison with that observed for healthy women. Method: We evaluated the incidence of sexual dysfunction in 60 patients with benign breast disease (fibroadenomas, breast cysts, breast pain and phyllodes tumor and 69 healthy women (control group. Participants completed the Sexual Quotient Questionnaire for Females (SQQ-F, the Beck Depression Inventory and the Beck Anxiety Inventory. Statistical analysis revealed that depression and anxiety were comparable between BBD and control groups (10.3 vs. 20.3% and 38.7 vs. 34.3%, respectively, p>0.05. The mean SQQ-F score (65.6±22.7 vs. 70.1±16.8; p>0.05 and sexual dysfunction (33.3 vs. 25.4%; p=0.324 were similar between BBD and control groups. Conclusion: We found no differences between women with BBD and healthy women in terms of the incidence of sexual dysfunction, anxiety and depression. Nevertheless, given the high prevalence of this condition, it is important to assess sexual quality of life, as well as overall quality of life, in women with BBD.

    One or more abnormal vertebrae detected on bone scintigraphy is a common finding in clinical practice, and it could pose a diagnostic dilemma especially in cancer patients, as either metastasis or benign disease may cause scintigraphic abnormality. The purpose of this study was to determine whether additional spine SPECT has a role in differentiating malignant from benign lesions in patients with back pain. We reviewed spine SPECT studies obtained over a three-year period in 108 patients. Among them, forty-five patients with abnormal SPECT and clinically followed records were evaluated (20 cancer patients were included). Uptake patterns were classified as follows: 1. Body: diffusely increased uptake, linear increased uptake of end plate, segmental increased uptake, and cold defect, 2 Posterior element; posterior to body (pedicle), posterior to intervertebral disc space (facet joint), and spinous process. Lesions were correlated with radiological findings and with final diagnosis. Sixty-nine bone lesions were detected on SPECT images, including 18 metastases, 28 degenerative diseases and 21 compression fractures. Cold defect (6) and segmental increased uptake (5) were dominant findings in metastasis: linear increased uptake (12), and facet joint uptake (15) were in degenerative change; and diffuse increased uptake (9), and linear increased uptake (9) were in compression fracture. Cold defect and segmental increased uptake of body were characteristic findings of metastasis, but care should be taken because compression fracture also shows segmental increased uptake in some cases. Degenerative disease was easily diagnosed because of the typical finding of linear increased uptake of end plate and facet joint. Therefore, additional bone SPECT after planar bone scan would be helpful for differentiating metastasis from benign condition in cancer patients

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