    Radioiodine ((131)I) therapy of benign thyroid diseases was introduced 70 yr ago, and the patients treated since then are probably numbered in the millions. Fifty to 90% of hyperthyroid patients are cured within 1 yr after (131)I therapy. With longer follow-up, permanent hypothyroidism seems...... 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...... predicts the outcome from (131)I therapy. The individual radiosensitivity, still poorly defined and impossible to quantify, may be a major determinant of the outcome from (131)I therapy. Above all, the impact of (131)I therapy relies on the iodine-concentrating ability of the thyroid gland. The thyroid...

    With regard to the treatment of differentiated non-medullary thyroid carcinoma, there is controversy over whether radiation from a diagnostic radioiodine ({sup 131}I) application really does have a suppressive effect on the uptake of subsequent therapeutic {sup 131}I (so-called thyroid stunning). However, inherent difficulties in exact remnant/metastatic tissue volumetry make it difficult to quantify how much diagnostic {sup 131}I is actually absorbed (absorbed energy dose) and hence to decide whether a threshold absorbed dose exists beyond which such stunning would occur. Since in benign thyroid disease the target volume can be readily quantified by ultrasonography, we sought to determine definitely whether stunning of thyroid cells occurs upon a second application of radioiodine 4 days following the first one. We therefore studied 171 consecutive patients with benign thyroid disease (diffuse goitre, Graves' disease, toxic nodular goitre) who received two-step {sup 131}I therapy during a single in-patient stay. For application of both calculated {sup 131}I activities we performed kinetic dosimetry of {sup 131}I uptake, effective half-life and absorbed dose. At the second application, patients showed significant stunning (a 31.7% decrease in {sup 131}I uptake, from 34.7%{+-}15.4% at first application to 23.7%{+-}12.3% at second application, P<0.0005) without a significant difference in effective half-life (4.9{+-}1.3 vs 5.0{+-}1.7 days, P>0.2). ANOVA showed that the extent of stunning was influenced significantly only by the absorbed energy dose at first application (F=13.5, P<0.0005), while first-application {sup 131}I activity, target volume, gender and thyroid function had no influence (all F{<=}0.71, all P>0.4). There was no significant correlation between extent of thyroid stunning and first-application {sup 131}I activity (r=0.07, P>0.3), whereas there was a highly significant correlation between thyroid stunning and first absorbed energy dose (r=0.64, P

  5. Guideline for radioiodine therapy for benign thyroid diseases (version 3)

    International Nuclear Information System (INIS)

    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 3rd version. (orig.)

  6. Radioiodine therapy of benign thyroid diseases: Graves' disease - current aspects

    International Nuclear Information System (INIS)

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

  7. Patient management in radioiodine therapy of benign thyroid disease

    International Nuclear Information System (INIS)

    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.

  9. Results of radioiodine therapy of benign thyroid disease

    International Nuclear Information System (INIS)

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

    Full Text Available Background: Papillary thyroid microcarcinoma (PTMC is a relatively common entity in the general population. Aim: To present our experience with papillary thyroid microcarcinoma of the thyroid as an incidental finding in patients treated surgically for presumably benign thyroid disease. Settings and Design: Histology reports of patients treated surgically with a preoperative diagnosis of benign thyroid disease were reviewed to identify patients with PTMC. Patients with a preoperative diagnosis of thyroid cancer were excluded from this study. Materials and Methods: The files of 380 patients who underwent surgery for presumably benign thyroid disease in our hospital from 1990 to 2002 were reviewed. Data regarding patient′s demographics, pathology findings, management and outcomes, were retrieved. Statistical Analysis Used: The findings are expressed as absolute numbers and as percentages (with reference to the total number of patients of this study. Results: Twenty-seven patients with PTMC diagnosed incidentally following thyroid surgery for presumably benign thyroid disease (27/380 or 7.1% (multinodular goiter = 20 patients, follicular adenoma = 6 patients, diffuse hyperplasia of the thyroid = 1 patient are presented. Mean diameter of PTMC was 4.4 mm. In 11 patients (40.7% the tumor was multifocal and in about half of them tumor foci were found in both thyroid lobes. In two patients the tumor infiltrated the thyroid capsule. Total/near-total thyroidectomy was performed in all these patients (in three as completion thyroidectomy. All patients received suppression therapy and 20 of them underwent adjuvant radioiodine therapy. Follow-up (mean 4.56 years, range 1-12 years was completed in 25 patients; all these patients were alive and disease-free. Conclusions: PTMC is not an uncommon incidental finding after surgery for presumably benign thyroid disease (7.1% in our series. The possibility of an underlying PTMC should be taken into account in the

  11. Dosimetry prior to I-131-therapy of benign thyroid disease

    International Nuclear Information System (INIS)

    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

    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.

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

  15. Dose concepts and dosimetry for radioiodine therapy of benign thyroid diseases

    International Nuclear Information System (INIS)

    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.)

  16. Stunning in radioiodine therapy of benign thyroid disease. Quantification and therapeutic relevance

    International Nuclear Information System (INIS)

    In radioiodine therapy of benign thyroid disease, a reduction of radioiodine uptake is known for consecutive administrations of 131I, which needs to be considered in therapy planning. Aim: Analysis of uptake reduction with regard on the time interval between radioiodine administration and the delivered dose to the thyroid tissue. Patients, methods: 200 patients were enrolled in the study and distributed into two groups (matched for diagnoses), each containing 32 patients with Graves' disease (target dose 250 Gy), 24 with focal (400 Gy), 44 with disseminated thyroid autonomy (150 Gy). In one group, a second fraction of radioiodine was given after 48 h (2d) due to an unexpected low radioiodine uptake or effective half-life, whereas in the other group the second fraction was given after 96 h (4d). Results: There was no significant difference between delivered doses due to the first fraction after four days: 2d: 86 ± 48 Gy (extrapolated) vs. 4d: 87 ± 41 Gy, p > 0.05. In 2d, delivered dose at time of second administration was significantly lower (51 μ 29 Gy) than in 4d (p < 0.01). The radioiodine uptake of the second fraction relative to the initial uptake was significantly lower in the 4d (4d: 63 ± 25% vs. 2d: 82 ± 24%, p < 0.01). In addition, a correlation between uptake reduction and delivered dose and an influence of the time interval between radioiodine administrations could be shown. Conclusions: Relative uptake of subsequent radioiodine fractions decreases with time after first administration and with increasing delivered dose to the thyroid. If a second fraction of 131I is given at an earlier time, the same therapeutic effect can be reached using lower amounts of activity, minimising radiation exposure and increasing efficiency of radioiodine therapy.

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

  19. In-vivo isotope diagnosis and radioiodine therapy of benign thyroid diseases

    International Nuclear Information System (INIS)

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

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

    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 ({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

The book also covers all aspects of thyroid surgery, including surgical treatment of hyperthyroidism; papillary, follicular, and other carcinomas; thyroidectomy; and prevention and management of complications

  5. Measurement of incorporation in family members of patients with benign thyroid diseases after radioiodine therapy

    International Nuclear Information System (INIS)

    Aim: Patients exhale I-131 after radioiodine therapy. In this study we quantify the amount of radioactivity and resulting thyroid doses found in people living in close contact to patients treated with I-131 after their release from a therapy ward. Methods: For 31 relatives of 25 patients treated with I-131 the incorporation was monitored using the thyroid probe of a whole body counter. These values are used for a determination of thyroid doses. Results: 11 of the 31 monitored persons had a thyroid activity of less than the minimal detectable activity of 13 Bq. The mean value of the remaining 20 people was 104 Bq in the thyroid resulting in a mean thyroid dose of 0.2 mSv (Maximum: 2 mSv). Conclusion: the intake of I-131 for persons in close contact to patients after dismissal from a therapy ward is low. In no case an effective dose exceeding 1 mSv was observed. (orig.)

    Background. The Chernobyl Nuclear Power Plant (CNPP) accident exposed a large number of inhabitants to internal (131)I radiation. The associations between internal (131)I 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 (131)I 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 (131)I 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 (131)I 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. PMID:27019779

  9. Thyroid diseases

    International Nuclear Information System (INIS)

    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.

  10. Thyroid disease in the pediatric patient: emphasizing imaging with sonography

    International Nuclear Information System (INIS)

    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).

  11. Influence of preceding diagnostic and therapeutic procedures on the radioiodine therapy of benign thyroid diseases

    International Nuclear Information System (INIS)

    Before and until 3 weeks after application of nonionic CA iodine and the 20-min-technetium-thyroid-uptake was measured in serum and urine in 23 euthyroid patients, which were given intravenously nonionic CA during heart catheterization. Concerning the possible influence of iodine contamination on a subsequent radioiodine therapy the following aspects result from the study: the time interval between application of CA and therapy has to be at least 4-6 weeks to avoid dilution of the radioiodine by iodine being released from the contrast agents. The thyroid-uptake of Technetium or Iodine after administration of CA is not constant over time but reaches its original value only in a gradual way (60% of the initial value 3 weeks after the CA were given); that means, the iodine-uptake during, radioiodine therapy can be higher than it was at the time the dose was calculated. Concerning the possible influence of preceding therapeutic procedures on the therapy with radioiodine the pretreatment with antithyroid drugs plays the most important role. Antithyroid drugs of the thiourylene group have been shown by many study groups to have a radioprotective effect. Other large studies however could not demonstrate any effect of antithyroid medication on the results of radioiodine therapy. All studies so far existing have in common that they are not strongly randomized with regard to the patient groups, because generally only in severe cases of hyperthyroidism additional antithyroid drug treatment has been employed, therefore it might be the case that the radioprotective effect of antithyroid drugs may be caused only by selection artifacts. The contradictory results of the different studies justify the practical way in so far as there are no reasonable objections against the pretreatment with antithyroid drugs to restore euthyroidism before starting the therapy with radioiodine.

    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.

    In the last years an increase in thyroid nodules detection has been reported from several epidemiological studies. This trend is largely due to the routine use of diagnostic sonography procedures in clinical practice. Thyroid nodules, both palpable or not palpable, rarely turn out to be malignant. Fine-needle aspiration cytology (FNAc) plays a central role in establishing the nature of the nodule. Excluded the presence of malignant lesions, which are generally treated with surgery, physicians are faced with a variety of therapeutic options, and choosing the optimal approach can be a difficult task. These include a periodic follow-up alone without treatment, the iodine supplementation, the thyroid-hormone suppressive therapy, the radioiodine administration, the percutaneous ethanol injections, and the new technique of laser photocoagulation. In all cases, decisions on the management of benign thyroid nodules should always be based on clinical target and a careful analysis of benefits and risks to the patient. PMID:18581970

    Conclusions: We interpret the elevated thyroid vascularization and low magnesium levels as signs of an inflammatory process related to the musculoskeletal changes. Improvement of thyroid function and morphology can be achieved after correcting the influence of stressors together with the supplementation regime. We hypothesize that the central biochemical event in thyroid disease is that of an acquired, altered mitochondrial function due to deficiency of magnesium, selenium, and coenzyme Q10.

Preoperative histological confirmation of malignancy is frequently unavailable and some patients will subsequently be found to have benign disease. Here, we review our experience with Whipple\\'s procedure for patients ultimately proven to have benign disease. The medical records of all patients who underwent Whipple\\'s procedure during a 15-year period (1987-2002) were reviewed; 112 patients underwent the procedure for suspected malignancy. In eight cases, the final histology was benign (7.1%). One additional patient was known to have benign disease at resection. The mean age was 50 years (range: 30-75). The major presenting features included jaundice (five), pain (two), gastric outlet obstruction (one), and recurrent gastrointestinal haemorrhage (one). Investigations included ultrasound (eight), computerised tomography (eight), endoscopic retrograde cholangiopancreatography (seven; of these, four patients had a stent inserted and three patients had sampling for cytology), and endoscopic ultrasound (two). The pathological diagnosis included benign biliary stricture (two), chronic pancreatitis (two), choledochal cyst (one), inflammatory pseudotumour (one), cystic duodenal wall dysplasia (one), duodenal angiodysplasia (one), and granular cell neoplasm (one). There was no operative mortality. Morbidity included intra-abdominal collection (one), anastomotic leak (one), liver abscess (one), and myocardial infarction (one). All patients remain alive and well at mean follow-up of 41 months. Despite recent advances in diagnostic imaging, 8% of the patients undergoing Whipple\\'s procedure had benign disease. A range of unusual pathological entities can mimic malignancy. Accurate preoperative histological diagnosis may have allowed a less radical operation to be performed.

    To evaluate the usage of duplex power Doppler ultrasound (PDUS) for the differentiation of benign and malignant thyroid nodules. We prospectively examined 77 thyroid nodules in 60 patients undergoing ultrasound-guided fine needle aspiration biopsy (FNAB). Each nodule was described according to size, inner structure, borders, parenchymal echogenicity, peripheral halo formation, and the presence of calcification (Bmode ultrasound findings). Vascularity as determined by PDUS imaging was defined as non-vascular, peripheral, central, or of mixed type. For each nodule, the pulsatility index (PI) and resistive index (RI) values were obtained. Results of FNAB and surgical pathological examination (if available) were used as a proof of final diagnosis to categorize all nodules as benign or malignant. A receiver operating characteristic (ROC) curve analysis was performed to establish cut-off, sensitivity, and specificity values associated with RI-PI values. A significant relationship was observed between malignancy and irregular margins, microcalcifications, and hypoechogenicity on ultrasound examination (p < 0.05). The pattern of vascularity as determined by PDUS analysis was not a statistically significant criterion to suggest benign or malignant disease in this study (p > 0.05). The central, peripheral, and mean RI-PI values were higher in malignant nodules when compared to the other cytologies (p < 0.05). Vascularity is not a useful parameter for distinguishing malignant from benign thyroid nodules. However, RI and PI values are useful in distinguishing malignant from benign thyroid nodules

    The origins of benign prostatic diseases, such as benign prostatic hyperplasia (BPH) and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS), are poorly understood. Patients suffering from benign prostatic symptoms report a substantially reduced quality of life, and the relationship between benign prostate conditions and prostate cancer is uncertain. Epidemiologic data for BPH and CP/CPPS are limited, however an apparent association between BPH symptoms and cardiovascular disease (CVD) has been consistently reported. The prostate synthesizes and stores large amounts of cholesterol and prostate tissues may be particularly sensitive to perturbations in cholesterol metabolism. Hypercholesterolemia, a major risk factor for CVD, is also a risk factor for BPH. Animal model and clinical trial findings suggest that agents that inhibit cholesterol absorption from the intestine, such as the class of compounds known as polyene macrolides, can reduce prostate gland size and improve lower urinary tract symptoms (LUTS). Observational studies indicate that cholesterol-lowering drugs reduce the risk of aggressive prostate cancer, while prostate cancer cell growth and survival pathways depend in part on cholesterol-sensitive biochemical mechanisms. Here we review the evidence that cholesterol metabolism plays a role in the incidence of benign prostate disease and we highlight possible therapeutic approaches based on this concept. PMID:21862201

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

    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.

  17. Prevalence of BRAF T1799A mutations in benign and malignant thyroid tumors and tumor-like thyroid lesions

    International Nuclear Information System (INIS)

    Full text: An increased incidence of thyroid cancer after the Chernobyl accident evoked a strong need in an early and accurate cancer diagnosis. Spectrum of thyroid diseases is wide, ranging from tumor-like lesions such as thyroiditis and various types of goiter, benign adenomas to malignant follicular, papillary, medullary and anaplastic (undifferentiated) cancer. Differential morphological diagnosis of these diseases is sometimes complicated. Therefore, much of attention has been recently paid to additional auxiliary diagnostic means, in particular to molecular and genetic assays. One of the most informative markers of papillary thyroid carcinoma (PTC) is a BRAF point mutation that has been shown to occur with a relatively high rate in PTCs but not in follicular cancer and benign lesions. The purpose of the current study was an investigation of hotspot BRAF T1799A mutation prevalence in a series of tumor-like thyroid lesions and thyroid tumors. For the study we collected thyroid tissue specimens from 44 patients living in the central region of the Russian Federation (8 males and 36 females; age range 23 to 69 years, 46 years old, mean) who were surgically treated in the Clinic of Medical Radiological Research Center of Russian Academy of Medical Sciences. Included in the study were 32 cases of malignant thyroid tumors (26 papillary, 4 follicular and 2 medullary carcinomas), 5 benign (follicular adenomas), and 7 tumor-like lesions (5 nodular goiters and 2 lymphocytic thyroiditis). Histological classification was made according to the criteria described by LiVolsi (1990) and Rosai and colleagues (1992). Remaining excess tissue specimens of thyroid benign and malignant lesions and surrounding normal thyroid not needed for histological examination were used for DNA extraction. Genomic DNA was analyzed for the BRAF mutations by mutant allele specific polymerase chain reaction. DNA from PTC tissue previously determined to harbor mutant BRAF was used as a positive

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

    Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.

    Pediatric thyroid diseases cover a large spectrum of congenital and acquired forms, ranging from congenital primary or central hypothyroidism, autoimmune thyroid disease, iodine deficiency, rare genetic defects of thyroid hormone action, metabolism and cell membrane transport to benign nodules and malignant tumors. The previous 15 papers of the textbook Paediatric Thyroidology gave a systematic overview of the current knowledge and guidelines on all these diseases. In this final paper, the authors collected a series of patient histories from their clinics illustrating frequently encountered clinical problems and providing key learning points and references to each case. Although not fully comprehensive, it aims at providing relevant clinical knowledge on thyroid diseases of the neonate, the child, and the adolescent. PMID:25231455

    Both Graves' disease and chronic thyroiditis (Hashimoto's thyroiditis) are autoimmune diseases of thyroid gland. Graves' disease is caused by stimulation of TSH receptor located on the thyroid gland by an antibody, which is known as TSH receptor antibody (TRAb). Furthermore, this may lead to hyperplasia and hyperfunction of the thyroid gland. On the contrary, the cause of Hashimoto's thyroiditis is thought due to a TSH stimulation-blocking antibody (TSBAb) which blocks the action of TSH hormone and subsequently brings damage and atrophy to thyroid gland. Approximately 15-20% of patients with Graves' disease had been reported to have spontaneous hypothyroidism resulting from the chronic thyroiditis (Hashimoto's disease). Pathogenesis for chronic thyroiditis following anti-thyroid drug treatment in patients with Graves' disease remains unclear. It has been estimated that chronic thyroiditis or Hashimoto's disease, which occurs following the Graves' disease episode is due to extended immune response in Graves' disease. It includes the immune response to endogenous thyroid antigens, i.e. thyroid peroxidase and thyroglobulin, which may enhance lymphocyte infiltration and finally causes Hashimoto's thyroiditis. We report four cases of chronic thyroiditis (Hashimoto's disease) in patients who have been previously diagnosed with Graves' hyperthyroidism. In three cases, Hashimoto's thyroiditis occurs in 7 to 25 years after the treatment of Grave's disease; while the other case has it only after few months of Grave's disease treatment. The diagnosis of Hashimoto's disease (chronic thyroiditis) was based on clinical manifestation, high TSHs level, positive thyroid peroxidase antibody and thyroglobulin antibody, and supported by positive results of fine needle aspiration biopsy. Moreover, the result of histopathological test has also confirmed the diagnosis in two cases. All cases have been successfully treated by levothyroxine treatment. PMID:20305330

  5. Percutaneous radiofrequency ablation for benign nodules of the thyroid gland

    International Nuclear Information System (INIS)

    We wanted to evaluate the efficacy and safety of using ultrasound guided percutaneous radiofrequency ablation for the benign nodules of the thyroid gland. We studied 148 patients with benign thyroid nodules (200 total nodules) that were confirmed histopathologically, and we performed ultrasound guided radiofrequency ablation. The radiofrequency ablation was done 1 to 5 times per one nodule, and follow-up ultrasonography was performed one to nineteen months after the ablation procedures. The physical changes and the decrease of volume of the nodules were evaluated, and the complications related to radiofrequency ablation were observed. The mean initial nodule volume was 0.01-95.61 ml (mean; 6.83 ± SD of 10.63 ml) and the nodule volume after radiofrequency ablation was decreased to 0.00-46.56 ml (mean; 1.83 ± SD of 4.69 ml). The mean volume reduction rate was 73.2%. Reduction of more than 50% was noted in 90% of all cases. For 180 nodules (90%), the decrease was 50% or more, in 20 nodules (10%), the decrease was 49% or less. On gray-scale ultrasonogram obtained after ablation, the echogenicity of the nodules changed to darker, and on the doppler-sonogram, the vascular flow within the nodules disappeared in all cases. Most patients complained pain during or right after the procedure, but the pain was transient and subsided after medication. Two patients developed hoarseness that was improved in 1 week and 2 months, respectively. Sonoguided percutaneous radiofrequency ablation can be one of the treatments for benign nodules of the thyroid gland

  8. Diagnostics of thyroid diseases

    International Nuclear Information System (INIS)

    The recommendations of the Thyroid Section of the Deutsche Gesellschaft fuer Endokrinologie have been established with a view to diagnostic practice; they help to define the most appropriate diagnostic procedure in consideration of its diagnostic value, necessity, expenditure in terms of time and cost, and the hazard involved. Methodological progress and recent scientific findings have been considered as well as economic aspects and the available technical facilities. The decision on what method to apply in thyroid diagnostics and therapy should be based on a specific anamnesis and a detailed physical examination. The measured data must be compatible with the patient's symptoms and with unambiguously established clinical signs. In a progressively structured diagnostic procedure, one should always start with the simple, non-invasive in vitro techniques. Functional diagnostics of thyroid diseases is supplemented by thyroid scintiscanning with short-lived radionuclides and by thyroid cytology. Experience and precise knowledge help to save funds and reduce the radiation doses applied. Of course, uncertain diagnoses and untypical findings necessitate a wider application of diagnostic means than clinically more or less validated diagnoses. (orig./MG)

    Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases

    Full Text Available Currently the “gold standard” in diagnostics of thyroid tumors is a fine-needle aspiration cytology (FNAC. However, FNAC cannot discriminate between benign and malignant thyroid tumors in 15 to 30% of observations. In order to develop an additional tool for differential diagnostics of thyroid tumors we evaluated the diagnostic performance of 3-antigen serum autoantibody signature in groups of benign ( n = 22 and malignant ( n = 26 thyroid tumors using a dot-blot ELISA-based analysis The sensitivity and specificity of resultant array were estimated to be 55–60% and 95–100%, respectively ( p < 0.001 according to one-sided Fisher Exact Test. Thus, we created a prototype antigen array for differential diagnostics of thyroid tumors which can be regarded as a platform for design of more complicated panel, highly sensitive in thyroid cancer detection, which can significantly improve the accuracy of preoperative diagnosis of thyroid cancer.

    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.

  1. Asbestos-related benign pleural disease review

    International Nuclear Information System (INIS)

    Benign pleural disease is the commonest manifestation of asbestos exposure encountered by radiologists. Benign pleural thickening can appear as circumscribed parietal pleural plaques or as more diffuse thickening of the visceral pleura. Benign-asbestos induced pleural effusions are a significant and under-recognized manifestation of asbestos exposure with important sequelae, such as diffuse pleural thickening which may be associated with functional impairment and for which compensation may be sought. This review concentrates on the strengths and weaknesses of chest radiography and computed tomography for the detection and characterization of benign asbestos-related pleural disease and the relevance of imaging abnormalities to compensation and functional impairment.

    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.

  10. Thyroid diseases after Chernobyl accident

    International Nuclear Information System (INIS)

    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 T4 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 color Doppler ultrasound findings of malignant and benign thyroid nodules, and to identify differential points among them. 35 patients with palpable enlarged thyroid nodules were imaged by using with 7 MHz linear-array transducer. Color Doppler images were obtained in the transverse and longitudinal planes on the color setting for the thyroid gland. After setting receiver gain, velocity scale and filter were set to 6 cm / sec and 1, respectively. And we measured resistive index, pulsatility index, peak systolic velocity and end diastolic velocity from the fastest or next fast arterial signals in the thyroid nodules or in the margins of the thyroid nodules. Final diagnosis was confirmed by ultrasonography-guided or surgical biopsy. 25 cases of malignant nodule and 10 cases of benign nodule were confirmed histopathologically.On the color mapping, malignant nodules showed various internal flow signals from avascular to hyper vascular and no marginal flow signals in all cases, and benign nodules revealed 9 (36%) hypo vascular cases and 16 (64%)hyper vascular cases in the internal flow signals and increased marginal flow signals in all cases. On the spectral analysis, malignant nodules showed RI 0.7 (0.63{approx}0.83) in hyper vascular internal flow signals and RI 0.93(0.67{approx}1.00) in hypo vascular internal flow signals, and measured PI was 1.39 (1.03{approx}2.11), 2.71 (0.97{approx}4.81),respectively. and in benign nodules, measured RI was 0.65 (0.5{approx}0.88) and PI was 0.92 (0.59{approx}1.90).

  13. Skeletal scintigraphy in benign and malignant disease

    International Nuclear Information System (INIS)

    This paper begins with a discussion of the technical factors in skeletal scintigraphy, including collimation, the use of three-phase bone scan, and single-photon emission computed tomography. Skeletal scintigraphy for benign conditions is commonly indicated for the patient presenting with pain (trauma, sports-related injury, posttraumatic pain syndrome, painful orthopedic prosthesis) and for the patient with abnormal laboratory test results (metabolic bone disease, Paget disease). For malignant conditions, the bone scan is useful in the evaluation of metastases in patients with extraosseous malignancies and primary bone tumors. The discussion addresses the various scan patterns seen in the more common tumors, such as prostate carcinoma, breast carcinoma, and lung carcinoma. Bone scintigraphy is an exquisitely sensitive modality. With some understanding of the techniques necessary for obtaining the optimal bone scan, and of the patterns that can be seen in various clinical conditions, the radiologist will find the bone scan a very specific tool for evaluating both benign and malignant diseases

  16. Diffusion-weighted MR imaging and ADC mapping in differentiating benign from malignant thyroid nodules

    International Nuclear Information System (INIS)

    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

  17. Application of Real-time Ultrasound Elastography in Diagnosing Benign and Malignant Thyroid Solid Nodules

    International Nuclear Information System (INIS)

    Real-time ultrasound elastography (US-E) is a helpful tool in diagnosing thyroid nodules. This study aims to evaluate thyroid solid nodules, to establish the accuracy of US-E in providing information on the nature of these nodules, and to assess the clinical value of elasticity scores (ES) and strain ratio (SR) in differentiating thyroid solid nodules and to explore its distribution characteristics using pathological analysis as reference. Traditional ultrasonography and US-E were performed on 131 thyroid solid nodules (99 benign ones and 32 malignant ones) in 120 patients (78 females and 41 males). Three radiologists evaluated the nodules based on a four-degree elasticity scoring system. The nodules were classified according to the ES as soft (ES 1-2) or hard (ES 3-4). The SR was calculated online. The sensitivity and specificity of the ES for thyroid cancer diagnosis were 78% and 80%, respectively. SR values ≥ 2.9 used as a standard to distinguish benign from malignant nodules had a sensitivity of 87% and a specificity of 92%. The SR of the benign lesions was 1.64±1.37, which was significantly different from that of malignant lesions, which was 4.96±2.13 (P<0.01). Both the ES and SR were higher in malignant nodules than those in benign ones. Real-time US-E was a useful index in the differential diagnosis of thyroid solid nodules. It can provide quantitative information on thyroid nodule characterization and improve diagnostic confidence

  18. The diagnosis of thyroid diseases

    International Nuclear Information System (INIS)

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

  19. Role of scintigraphy in the current diagnosis and management of thyroid diseases

    International Nuclear Information System (INIS)

    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 131I 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 123I 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)

    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{sub 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.

    Incidental papillary carcinoma of the thyroid in patients treated surgically for benign thyroid diseases including Graves' disease is a known phenomenon. However, the management of these patients remains an issue of concern and controversy for those who care for them. We report a case of metastatic papillary carcinoma of the thyroid in a patient previously treated for Graves' disease. The subject of this presentation is a 50-year-old lady who was diagnosed with Graves' disease at the age of 29, for which she had a subtotal thyroidectomy following failure of medical and radioactive iodine treatment. Three years later, the patient was referred to our nuclear medicine department with a clinical diagnosis of suspected metastatic lymph nodes presumably from a thyroid malignancy.She had an 123I diagnostic whole body scan that showed 123I avid areas in the thyroid bed as well as left cervical lymph nodes, which later turned out to be metastatic papillary carcinoma of the thyroid on histology. She was treated with therapeutic doses of 131I. Follow-up radioactive iodine scans and serum thyroglobulin assays showed no evidence of malignant thyroid tissue. The occurrence of papillary carcinoma of the thyroid after a subtotal thyroidectomy for Graves' disease is hereby reported. The need for vigilance and regular follow-up in patients who receive all forms of treatment for benign thyroid diseases is emphasized. PMID:24705115

  9. The radiation therapy of benign diseases

    International Nuclear Information System (INIS)

    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)

    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.

    International Nuclear Information System (INIS)

    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

  13. Perspectives of radiation therapy in benign diseases

    International Nuclear Information System (INIS)

    Purpose: the numbers of patients with nonmalignant diseases referred for radiation therapy had to be evaluated for the last 4 years. Patients and methods: in the years 2002, 2004, and 2005 radiation therapy was performed in 61, 40, and 26 patients, respectively. Regularly, more women than men were treated, median age annually was 57, 54, and 55 years, respectively (table 1). The radiotherapy scheme was not modified within the evaluated period. Results: the proportion of nonmalignant diseases among all patients treated decreased from 4.7% in 2002 to 3.3% in 2004 and 2.2% in 2005, respectively. A shift was noticed toward the treatment of four main diseases (endocrine orbitopathy, prevention of heterotopic ossification, meningeoma, tendinitis, table 2). The number of referring physicians decreased from 19 to six. Conclusion: due to administrative restrictions for treatment in hospitals, budget restrictions in private practices and lasting, insufficient revenues for radiotherapy in nonmalignant diseases, radiation therapy for the entire group of benign diseases is endangered.

    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.

  15. SPECT/CT application in benign diseases diagnostics

    International Nuclear Information System (INIS)

    Full text: Introduction: The use of the hybrid imaging methods increases more and more in the diagnostic process of many diseases. They combine functional anatomical data and exact location of disease processes. Although it was introduced later in nuclear medicine practice, hybrid single photon emission tomography combined with computer tomography (SPECT/CT), is of increasing use. What you will learn: its application in nuclear cardiology is associated with rapid attenuation correction and the calcium score determination. In the thyroid and parathyroid studies the localization of radiopharmaceutical inclusion takes part in the diagnosis of normal and ectopic adenomas located on Struma and hyperplastic conditions. In nuclear pulmonology evaluation criteria for ventilator and perfusion disorders require a comparison with radiographic findings that are best achieved by SPECT-CT. In the study of obscure febrile conditions the tissue involvement of inflammatory processes is specifying. SPECT/CT differentiates physiological from pathological radiopharmaceutical accumulation. Careful evaluation of the CT component sets the average 10% significant unexpected findings: effusions, lymphadenopathy, tumor masses, and metastases. Discussion: SPECT/ CT achieves better specificity of the assay (avoiding attenuation phenomena, specifying the presence or absence of anatomic substrate in the investigation of thyroid, parathyroid glands in the diagnosis of pulmonary embolism), exact location (ectopia, inflammation), obtaining additional information (calcium score, significant unexpected findings). This achieves improvement of diagnostic accuracy, reduce non-diagnostic conclusions. Shorten additional studies, the volume of surgical interventions may be influenced. Most studies have low-dose CT components without significant impact on the radiation burden. With suitable equipment it is able to merge nuclear medicine with contrasting images. Conclusion: In the diagnosis of benign

    Fine needle aspiration (FNA) cytology, being the mainstay to diagnose thyroid nodules, does not provide definitive results in a subset of patients. The use of molecular markers testing has been described as a useful aid in differentiation of thyroid nodules that present with an indeterminate cytodiagnosis. Molecular tests, such as the Afirma gene classifier, mutational assay and immunohistochemical markers have been increasingly used to further increase the accuracy and defer unnecessary surgeries for benign thyroid nodules. However, in light of the current literature, their emerging roles in clinical practice are limited due to financial and technical limitations. Nevertheless, their synergistic implementation can predict the risk of malignancy and yield an accurate diagnosis. This review discusses the clinical utility of various molecular tests done on FNA indeterminate nodules to avoid diagnostic thyroidectomies and warrant the need of future multi-Institutional studies.

  18. Investigation on the value of spectral CT imaging in diagnosis of benign and malignant thyroid nodules

    International Nuclear Information System (INIS)

    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

    Full Text Available Purpose: The aim of this study was to evaluate the efficacy of radiofrequency (RF ablation for benign thyroid nodules and assess the usefulness of internal factors (ultrasonographic findings and external factors (treatment-related findings in prediction of treatment efficacy. Methods: We evaluated 22 benign thyroid nodules from 19 patients treated with RF ablation between March 2010 and January 2013. The internal and external factors of these nodules were retrospectively reviewed and correlated with the therapeutic success and the volume reduction ratio (VRR. The volume and size of the nodules were determined before treatment, and the VRR was calculated at 6-month and 1-year follow-up examinations after RF ablation. Therapeutic success was defined as a >50% volume reduction. Results: The mean VRRs were 66.1±18.7% at 6 months and 74.3±16.7% at 1 year. The therapeutic success rate after 6 months and 1 year was 81.8% and 90.9%, respectively. At the 1-year follow-up, the margin of the nodule correlated with therapeutic success. Most of the successfully ablated nodules showed well-defined margins on initial ultrasonography (18/20, 90% (P=0.026. In addition, nodules with ill-defined margins showed a tendency toward having a low VRR at the 6-month and 1-year follow-up examinations. Conclusion: RF ablation was effective in decreasing the volume of benign thyroid nodules. Thyroid nodules with well-defined margins tended to show successful outcomes at the 1-year follow-up examination after RF ablation.

    Full Text Available Background: Thyroid disorders are common endocrine disorders encountered in the African continent. Environmental and nutritional factors are often implicated in the occurrence of some thyroid disorders that occur in this part of the world. This is a narrative review that seeks to document the pattern, prevalence, and management of thyroid disorders in the continent. Materials and Methods: The search engine used for this review were PubMed and Google scholar. All available articles on thyroid disorders from the sub-African continent, published until May 2011, were included. Results: Iodine deficiency disorders (IDD which top the list of thyroid disorders and remain the commonest cause of thyroid disorders in the continent is often affected not only by the iodine status in the region but sometimes also by selenium deficiency and thiocyanate toxicity. The reported prevalence rates of endemic goiter range from 1% to 90% depending on the area of study with myxedematous cretinism still a prominent feature of IDD in only a few regions of the continent. The extent of autoimmune thyroid disorders remains unknown because of underdiagnosis and underreporting but the few available studies note a prevalence rate of 1.2% to 9.9% of which Graves diseases is the commonest of these groups of disorders. Rarer causes of thyroid dysfunction such as thyroid tuberculosis and amiodarone related causes are also documented in this review. The onset of new thyroid diseases following amiodarone usage was documented in 27.6% of persons treated for arrhythmia. Reports on thyroid malignancies (CA in Africa abound and differentiated thyroid malignancies are noted to occur more commonly than the other forms of thyroid CA. The documented prevalence rates of thyroid CA in the African continent are as follows (papillary: 6.7-72.1%, follicular: 4.9-68%, anaplastic: 5-21.4%, and medullary: 2.6%-13.8%. For the differentiated thyroid CA, there is a changing trend toward the more

    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

    While conventional ultrasound and laboratory testing can differentiate most thyroid conditions and malignancies, spectral dual-energy computed tomography (DECT) provides molecular data potentially useful in differential diagnosis of small, complex, and partially obscured hemorrhaged nodules with recent bleeding. To demonstrate that Gemstone Spectral Imaging (GSI) analysis of DECT data differentiates challenging benign thyroid nodule conditions in patients with intranodular hemorrhages. A retrospective study was conducted of 30 intranodular hemorrhage patients from 2010 to 2013, including 18 that underwent surgery and provided thyroid tissues for prospective histological analysis. Iodine and water content were determined in patient CT scans and ex vivo tissue specimen scans by reconstruction of raw CT data at 65 keV (optimal contrast). Slope of spectral curve (λ HU), effective atomic number (Z eff), and final pathological diagnosis were recorded. Iodine content, water content, Z eff, and λ HU significantly varied by region (intranodular hemorrhage, solid thyroid nodule, and adjacent margins) in patients and tissue specimens (P < 0.05). Intranodular hemorrhage exhibited elevated water concentrations (~1100 mg/mL), suggesting a practical threshold of 1075 mg/mL for differentiating intra-plaque hemorrhage and solid nodular regions. Spectral CT provided diagnostic information in 14 thyroid adenomas and four goiters (histologically confirmed in donor specimens), and eight thyroid adenomas and four nodular goiters based on clinical diagnosis. Diagnostically useful regional characteristic of intranodular hemorrhage in the thyroid was visualized via spectral CT employing material decomposition, potentially yielding additional molecular data about complex lesion characteristics no apparent in conventional imaging or laboratory methods.

  6. New approach for diagnosis of thyroid diseases

    International Nuclear Information System (INIS)

    Full text: Computerization development leads to the creation of a new information technology and expert systems. Expert system is a computer program that models analytical assessment of an expert in a certain field and uses for this purpose the available knowledge followed by the procedure of making a logical conclusion. Simple expert systems may be built by the question-answer principle. The procedure of making diagnosis with the help of an expert system was performed by a number of sequential steps. At first, while studying cytologic preparation the user answers in the interactive mode the 35 questions concerning qualitative characteristics of pathologic changes in thyroid tissue cells. These questions are expected to be answered yes/no. For example, nuclear structure/presence of nuclear invagination: yes/no. The answers will be automatically introduced to the X-matrixes in a certain row and column. Then, the software in the real-time mode performs the automatic comparison of the obtained X-matrix by turns with 6 standard matrixes (S-matrixes) that have been constructed by analogy (in the same format). S-matrixes characterize the main forms of thyroid pathology: papillary and follicular cancer, follicular adenoma, autoimmune thyroiditis, nodular colloid and diffuse toxic goiter. Standard matrices were formed taking into account generally accepted standards and weighting coefficient of the significance of each feature for certain nosology. Weighting coefficients were determined by means of expert evaluation. The software recorded the coincidence of xij X-matrix elements with the corresponding sij elements of each S-matrix. After that, the probability of a disease for each of six nosologic forms (diagnostic index) calculates using deduced by us formula, taking into account the weighting coefficient of the significance of a concrete qualitative parameter for each nosologic form. When all the elements of X-matrix and a concrete S-matrix coincided, diagnostic index

  7. Management of thyroid eye disease

    International Nuclear Information System (INIS)

    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.)

    The incidence of common bile duct (CBD) pathology in a group of patients with benign biliary disease (n = 505) was found to be 23.2 per cent. The spectrum included 111 patients (90.2 per cent) with CBD stones, 37 of whom (33.3 per cent) had no symptoms or findings pre-operatively indicating CBD involvement. Five patients had papillary stenosis, three had postoperative CBD strictures, one had a choledochal cyst and one had an external biliary fistula. Of the 100 CBDs measuring more than 10 mm in diameter, 90 harboured calculi. In the remaining 23 CBDs measuring less than 10 mm, calculi were present in 21. The presence of CBD calculi was demonstrated by intra-operative cholangiography in 49 patients. In the remaining patients (n = 74), the diagnosis of CBD pathology was made either by percutaneous transhepatic cholangiography, endoscopic retrograde cholangio-pancreatography, T-tube cholangiography or peroperative palpation. The surgical procedures performed included choledochotomy and T-tube drainage (n = 74), transduodenal sphincteroplasty (n = 27) and choledochoduodenostomy (n = 18). The overall mortality and morbidity of CBD exploration was 3.3 per cent and 24.4 per cent respectively, which was significantly greater than that for cholecystectomy alone (0.3 per cent and 8.6 per cent respectively). Transduodenal sphincteroplasty carried a much higher mortality (11 per cent) and morbidity (52 per cent) when compared with other procedures. PMID:3167536

    International Nuclear Information System (INIS)

    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.

  12. Benign oral pathology as a cause of false positive 131I uptake in thyroid carcinoma

    International Nuclear Information System (INIS)

    Full text: We present three thyroidectomised patients with a history of thyroid carcinoma who had non-metastatic 131I uptake due to benign oral pathology. A salivary gland study suggested impaired function but no obstruction was demonstrated on a sialogram. The symptoms resolved on antibiotic therapy and a subsequent 131I study was normal. A subsequent thallium study demonstrated physiological tracer distribution. A 35-year-old female with papillary cell carcinoma of the thyroid demonstrated a focus of uptake on the right hemi-mandible following both a diagnostic and a therapeutic dose of 131I. This area was tender and an OPG confirmed an area of liquefaction at this site. A 53-year-old female with medullary cell carcinoma of the thyroid demonstrated a focus of uptake in the right side of the maxilla following a diagnostic administration of 131I. An OPG confirmed an area of liquefaction around the apex of the right upper centre. These three cases illustrate salivary gland and dental inflammation as causes of false positive 131I uptake. It is important to differentiate non-metastatic 131I uptake from that due to functioning metastatic thyroid carcinoma in order to avoid inappropriate treatment with large additional doses of 131I. As in these patients, clinical assessment and the use of anatomical imaging or other isotopes such as thallium or technetium can be helpful in ruling out a mistaken diagnosis of metastasis

  13. Clinical significance of determination of serum TRAb levels in patients with thyroid diseases

    International Nuclear Information System (INIS)

    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)

    This study evaluated the usefulness of serum calcitonin (Ctn) in subjects without a suspicious history of medullary thyroid carcinoma (MTC) and with nodular thyroid disease without an indication for fine-needle aspiration (FNA) or with benign cytology. This was a prospective study that evaluated 421 patients with nodular disease without an indication for FNA and 602 patients with benign cytology. Patients with basal Ctn>10 pg/ml were submitted to calcium stimulation testing. Patients with stimulated Ctn>100 pg/ml were submitted to total thyroidectomy. Basal Ctn was10 pg/ml, 16/22 exhibited stimulated Ctn>100 pg/ml. Two of these 16 patients had MTC. The 2 patients with MTC had undetectable basal Ctn 6 months after surgery. Using a cut-off of 30 pg/ml in women and 60 pg/ml in men for basal Ctn, the 2 cases of MTC of our series would have been identified and there would have been no false-positive case. It should be noted that 14/16 patients with stimulated Ctn>100 pg/ml were false-positive cases. Although uncommon, even subjects without a suspicious history and with nodular thyroid disease without an indication for FNA or with benign cytology can have MTC. The measurement of Ctn permits the diagnosis of these cases. Our results favor the hypothesis that basal Ctn could be superior to stimulated Ctn. PMID:27203410

    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.

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

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

  18. Radiotherapeutic management of thyroid disease

    International Nuclear Information System (INIS)

    Outcomes of radiotherapy were analyzed in 19 patients with malignant lymphoma of the thyroid gland. Seventeen patients had stage I or II disease and two had stage IV disease. The male to female ratio was 2 : 17. Six patients were treated with radiotherapy alone and 13 were treated with combined-modality therapy. Patients were treated with 40 to 50 Gy megavoltage irradiation to the whole neck or to the neck and upper mediastinum. Combined modality therapy was used except for patients with low-grade lymphoma or for patients more than 70 years old. Chemotherapy consisted of CHOP or VEMP. Cause-specific survival was calculated using the Kaplan-Meier method. The 5-year cause-specific survival rate was 72.7% overall, and was 81.6% for patients with stage I or II disease. There were no treatment failures among patients who received radiation therapy alone. Therefore, combined-modality therapy may be unnecessary for patients with low-grade lymphoma of clinical stages I or II. (author)

  19. False-negative Results with the Bethesda System of Reporting Thyroid Cytopathology: Predictors of Malignancy in Thyroid Nodules Classified as Benign by Cytopathologic Evaluation

    The benign category of the Bethesda System for reporting thyroid cytopathology (BSRTC) predicts an incidence of malignancy from zero to three per cent. However, recent series report higher rates of malignancy ranging from eight to 14 per cent. Surgery is often performed for reasons other than their fine needle aspiration biopsy (FNAB) such as symptoms, nodule enlargement, or worrisome imaging. We hypothesized that an analysis of patients who underwent thyroidectomy despite a benign FNAB would...

  1. Ultrasound guided percutaneous microwave ablation of benign thyroid nodules: Safety and imaging follow-up in 222 patients

    International Nuclear Information System (INIS)

    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

  3. Interventions in patients with thyroid disease

    International Nuclear Information System (INIS)

    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

  7. Feasibility of Sentinel Lymph Node Detection in Nodular Thyroid Disease

    International Nuclear Information System (INIS)

    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.

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

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

    Full Text Available The endocannabinoid system is comprised of cannabinoid receptors (CB1 and CB2, their endogenous ligands (endocannabinoids, and proteins responsible for their metabolism participate in many different functions indispensable to homeostatic regulation in several tissues, exerting also antitumorigenic effects. The present study aimed to evaluate the clinical significance of CB1 and CB2 expression in human benign and malignant thyroid lesions. CB1 and CB2 proteins’ expression was assessed immunohistochemically on paraffin-embedded thyroid tissues obtained from 87 patients with benign (n=43 and malignant (n=44 lesions and was statistically analyzed with clinicopathological parameters, follicular cells’ proliferative capacity, and risk of recurrence rate estimated according to the American Thyroid Association (ATA staging system. Enhanced CB1 and CB2 expression was significantly more frequently observed in malignant compared to benign thyroid lesions (p=0.0010 and p=0.0005, resp.. Enhanced CB1 and CB2 expression was also significantly more frequently observed in papillary carcinomas compared to hyperplastic nodules (p=0.0097 and p=0.0110, resp.. In malignant thyroid lesions, elevated CB2 expression was significantly associated with the presence of lymph node metastases (p=0.0301. Enhanced CB2 expression was also more frequently observed in malignant thyroid cases with presence of capsular (p=0.1165, lymphatic (p=0.1989, and vascular invasion (p=0.0555, as well as in those with increased risk of recurrence rate (p=0.1165, at a nonsignificant level though, whereas CB1 expression was not associated with any of the clinicopathological parameters examined. Our data suggest that CB receptors may be involved in malignant thyroid transformation and especially CB2 receptor could serve as useful biomarker and potential therapeutic target in thyroid neoplasia.

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.).

    The neonatal period comprises the first four weeks of life. It is a period of adaptation where the skin often presents several changes: transient lesions, resulting from a physiological response, others as a consequence of transient diseases and some as markers of severe disorders. The presence of pustules in the skin of the newborn is always a reason for the family and for the assisting doctor to be worried, since the newborn is especially vulnerable to bacterial, viral or fungal infection. However, the majority of neonatal skin pustules is not infectious, comprising the benign neonatal pustulosis. Benign neonatal pustuloses are a group of clinical disease characterized by pustular eruptions in which a contagious agent is not responsible for its etiology. The most common ones are erythema toxicum neonatorum, the transient neonatal pustular melanosis and the benign cephalic pustulosis. These dermatoses are usually benign, asymptomatic and self-limited. It is important that the dermatologist and the neonatologist can identify benign and transient lesions, those caused by genodermatoses, and especially differentiate between neonates with systemic involvement from those with benign skin lesions, avoiding unnecessary diagnostic tests and worries.

    Although thyroid goiter is a common condition, it rarely results in Horner's syndrome. We report a case of a patient with an intrathoracic multinodular goiter complicated by Horner's syndrome. Benign thyroid disease was confirmed pathologically, and the patient's symptoms improved after surgery. In the literature, the major cause of Horner's syndrome is neoplasia, with malignant lesions being twice as frequent as benign tumors. An extensive review of the literature demonstrates a different repartition for thyroid neoplasia: including our case, 38 cases of Horner's syndrome secondary to a benign thyroid tumor are described, against only 8 cases caused by a thyroid carcinoma. We conclude that contrary to the commonly held opinion, Horner's syndrome is more often due to benign thyroid diseases than to thyroid malignancies. PMID:11891400

    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.

  1. Efficacy of needle biopsy in postradiation thyroid disease

    International Nuclear Information System (INIS)

    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

    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)

    Physiological changes during gestation are important to be aware of in measurement and interpretation of thyroid function tests in women with autoimmune thyroid diseases. 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). The best laboratory assessment of thyroid function is a free thyroid hormone estimate combined with TSH...

    Background: scleredma adultorum Buschke is a rare disorder characterized by thickening of the dermis of the neck, head and upper trunk. Its etiology is unknown, but there may be a preceding history of infection and there is a known association with diabetes mellitus. Women are more frequently affected. Usually, the disease is self-limiting but some patients show progressive disease. In these cases therapeutic options are poor, with only case reports and small series supporting their use. Case report: a 58-year-old patient with a scleredema of the neck and upper trunk is described, who was treated twice within 6 months by electron-beam radiation therapy. After the second course his symptoms improved significantly. A review of the literature of radiation treatment of this disease is given. Conclusion: regardless of the possible mechanisms in pathogenesis and treatment of scleredema adultorum Buschke, the application of ionizing radiation is an important, effective and well-tolerated therapy option in the treatment of severe cases and may candidate as the first-line treatment of this disease.

  7. Radiation therapy of benign diseases. What's new eight years after?

    International Nuclear Information System (INIS)

    The authors present an update version of the indications for radiotherapy in the management of benign diseases. This is based on available randomized trials and recent international meetings. Validated indications remain the prevention of resected heterotopic bone ossifications, keloids scars and pterygium and also treatment of arteriovenous malformations; the place of radiotherapy for malignant exophthalmia is more and more restricted. Randomized trials have demonstrated the efficacy of endo-brachytherapy in the prevention of restenosis after angioplasty but the use of embedded stent has replaced this indication. Macular degeneration is no more an indication of radiotherapy. Quality requirements for radiotherapy are identical for benign or malignant indications. (author)

    2014-07-01

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

    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.

    The role of vitamin D as an immune modulator has been emphasized in recent years, and low levels of the hormone were observed in several autoimmune diseases including multiple sclerosis and systemic lupus erythematosus. Vitamin D mediates its effect though binding to vitamin D receptor (VDR), and activation of VDR-responsive genes. While VDR gene polymorphism was found to associate with autoimmune thyroid diseases (AITDs), few studies examined levels of vitamin D in these patients and those t...

    The relationship between methylxanthine (Mx) consumption and benign breast disease was evaluated in a case-control study of 288 women with histologically confirmed benign breast lumps (203 dysplastic lesions and 85 benign tumors) and 2 groups of control women--285 patients in the hospital for acute conditions apparently unrelated to the consumption of Mx-containing beverages and 291 outpatients. The relative risk estimates of dysplastic breast lesions (fibrocystic disease), with allowance for all identified potential distorting factors, for women who drank 1-2 or 3 or more cups of coffee per day were 4.1 and 6.4, respectively, when the hospital controls were the comparison group and 2.0 and 3.7, respectively, when the outpatient controls were the comparison group. The relationship was even stronger when the total consumption of Mx-containing beverages (coffee plus tea) was considered and increased with increasing duration of use. The association was not explained by any of the major risk factors for fibrocystic breast diseases or by differences in general characteristics or other lifestyle habits between cases and controls. Mx consumption was not related to the risk of benign breast tumors (fibroadenomas). These findings support the hypothesis that Mx consumption is related to the risk of dysplastic lesions of the breast. PMID:3858587

  14. The influence of various amounts of 131-iodine on the proliferation of benign and malignant thyroid cells

    International Nuclear Information System (INIS)

    The aim of our work was to find a method to predict the sensitivity of different thyroid diseases towards 131-iodine individually for each patient who is going to have a 131-iodine treatment. We tried to determine the 131-iodine-uptake of benign primary thyroid cells and malignant thyroid (carcinoma) cell-lines (follicular -UCLA RO 82 W-1 and papillary -NPA'87). The following culture dishes were used: 75 cm2-flasks, 24-well plates and Palladium-covered dishes. We incubated 350000 cells per well with 3,7; 9,25; 18,5; 37; and 185 mbq 131-iodine/500 μl Hanks Balanced Salt Solution and 10 (5; 100; 0,1 and 0) μM non-active sodium-iodide for 2 minutes up to 72 hours. The amount of 131-iodine stored by the cells was measured with a Gamma-counter. The ability of the tested two cell-lines to take up 131-iodine was pretty low (about 0,02 % - 0,9 % of the added 131-iodine doses). In addition to that we controlled and determined the cell proliferation by staining them with Trypan-blue and counting using a phase-contrast-microscope. From the cell numbers we collected during 8 days control a growth curve could be prepared. There was a remarkable difference in the growth rate between 131-iodine-incubated (3,7 mbq) and non-incubated cells. The number of the irradiated cells was about 30 % lower. Furthermore we added 10 μM 13-cis retinoic acid to the nutrition media to attempt to rise the extent of the cells differentiation and therefor also the 131-iodine-uptake. Four days preparation with retinoic acid in the media caused a slight increase (10 %) of the 131-iodine-uptake in the RO 82 W-1-cells, 28 days incubation decreased the 131-iodine-uptake significantly (about 30 % - 70 %) and the cells died. After 10 days preparation with retinoic acid the NPA'87-cells also showed a decrease in the 131-iodine-uptake (∼40-50 %) and the cells died. (author)

  15. Benign thyroid disorders, radioiodine therapy and diagnosis related groups (DRGs): aspects of cost/benefit

    International Nuclear Information System (INIS)

    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.

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

  17. Computer-aided diagnosis system for classifying benign and malignant thyroid nodules in multi-stained FNAB cytological images

    International Nuclear Information System (INIS)

    An automated computer-aided diagnosis system is developed to classify benign and malignant thyroid nodules using multi-stained fine needle aspiration biopsy (FNAB) cytological images. In the first phase, the image segmentation is performed to remove the background staining information and retain the appropriate foreground cell objects in cytological images using mathematical morphology and watershed transform segmentation methods. Subsequently, statistical features are extracted using two-level discrete wavelet transform (DWT) decomposition, gray level co-occurrence matrix (GLCM) and Gabor filter based methods. The classifiers k-nearest neighbor (k-NN), Elman neural network (ENN) and support vector machine (SVM) are tested for classifying benign and malignant thyroid nodules. The combination of watershed segmentation, GLCM features and k-NN classifier results a lowest diagnostic accuracy of 60 %. The highest diagnostic accuracy of 93.33 % is achieved by ENN classifier trained with the statistical features extracted by Gabor filter bank from the images segmented by morphology and watershed transform segmentation methods. It is also observed that SVM classifier results its highest diagnostic accuracy of 90 % for DWT and Gabor filter based features along with morphology and watershed transform segmentation methods. The experimental results suggest that the developed system with multi-stained thyroid FNAB images would be useful for identifying thyroid cancer irrespective of staining protocol used.

  18. Pediatric thyroid disease: when is surgery necessary, and who should be operating on our children?

    2013-01-01

    Surgical diseases of the thyroid in the pediatric population represent a diverse set of both benign and malignant conditions. Overall, incidence is rare. Benign conditions include Graves' disease, toxic adenomas, congenital hyperthyroidism, and goiter. Differentiated thyroid cancer (DTC) and medullary thyroid carcinoma (MTC), with its related familial cancer syndromes, are the most common malignancies. Near-total or total thyroidectomy is the appropriate surgery for thyroid cancer, with/out central lymph node dissection. Emerging practice guidelines from professional societies are helpful, although they generally have not addressed surgical management of the pediatric patient. Thyroidectomy in children is associated with a higher rate of complications, such as recurrent laryngeal nerve injury and hypoparathyroidism, as compared to the surgery in adults. Therefore, it is essential that pediatric thyroidectomy be performed by high-volume thyroid surgeons, regardless of specialty. Case volume to support surgical expertise usually must be borrowed from the adult experience, given the relative paucity of pediatric thyroidectomies at an institutional level. These surgeons should work as part of a multidisciplinary team that includes pediatric endocrinologists and anesthesiologists, pediatricians, nuclear medicine physicians, and pathologists to afford children the best clinical outcomes.

  19. Prevalence rate of thyroid diseases among autopsy cases of the atomic bomb survivors in Hiroshima, 1951-1985

    International Nuclear Information System (INIS)

    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

  2. Prevalence of benign and malignant thyroid nodules in patients with previous history of radiotherapy for Tinea capitis in childhood (in khorosan province)

    International Nuclear Information System (INIS)

    Increased prevalence of thyroid cancer was noted in patients with previous history of radiotherapy of the head and neck region in childhood. According to previous research, radiotherapy for Ti nia capitis was using up to 30 years ago in Khorasan Province. This study tries to evaluate prevalence of benign and malignant thyroid nodules and detect and treat these patients earlier to prevent more complications and increased cost. Methods and patients: Using mass media, we recalled all patients with history of radiotherapy for Tinea capitis in childhood. A questionnaire was filled for each patient and thyroid examination, thyroid scan and thyroid sonography were performed. Fine needle aspiration biopsy (FNAB) was done if a thyroid nodule larger than 1 cm was palpable. Serum TSH was measured in all patients. Also thyroid surgery was recommended for all patients with thyroid nodules more than 1 cm. A control group was defined from a group of patients who referred for non thyroidal sonography to radiology department of Ghaem hospital. These patients also were evaluated by clinical examination and thyroid sonography. Results: We studied 180 patients with mean age of 47.7 years and 127 age and sex m etched controls. Thyroid nodules was palpated in 45.5% of patients and 7% of controls (P0.01). The mean largest diameter of nodules were 24.8 mm in patients and 10.8 mm in control group (P<0.001). 75% of patients were agreed with FNAB and 5% of them had suspicious cytology results. No suspicious or malignant results was noted in control group. Twenty seven patients (33.7%) were operated. Pathological results were benign in 89.9% and malignant in 1% of patients. His study showed that thyroid nodules and thyroid neo plasma were significantly more larger in the patients group. Thyroid neoplasm were more frequent in younger patients with latent thyroid (from radiotherapy) of less than 40 years, so aggressive evaluation is recommended in these group

  5. Application of diffusion-weighted MR imaging in the diagnosis of thyroid disease

    International Nuclear Information System (INIS)

    Objective: To analyze and summarize the characteristics of thyroid diseases on the MR diffusion-weighted imaging. Methods: Forty-two patients with thyroid lesions,including 10 males and 32 females [age range 20-72 years, mean age (42±13) years] underwent MR DWI before surgery and biopsy. The diagnoses of thyroid lesions were confirmed by pathological results. ADC values of benign and malignant nodules, with different b values (b values was 300, 500 and 800 s/mm2), were generated by using post-processing software Functool of GE company (USA). The independent-samples t test was used and ROC curve was made to evaluate the diagnostic efficiency of the ADC values by using statistical software SPSS 12.0. Results: Histologically, there were 28 benign lesions and 14 malignant lesions. Benign lesions included 20 cases of thyroid adenoma, 6 cases of nodular goiter and 2 cases of Hashimoto's thyroiditis respectively. Malignant lesions consisted of 11 cases of thyroid papillary carcinoma, 2 cases of follicular thyroid cancer, and 1 case of dysplasia mean ADC value of benign thyroid lesions was (2.39 ±0.38) ×10-3 mm2/s and mean ADC value of malignant thyroid lesions was ( 1.60 ± 0.56) × 10-3 mm2/s with b value of 300 s/mm2. The statistical difference was significant between them (t=5.35, P<0.05). The statistical difference of mean A DC values,between benign and malignant nodules with b value of 500 s/mm2 [(1.85 +0.33 ) × 10-3 mm2/s and (1.65 ± 0.42) × 10-3 mm2/s], was insignificant (t=1.70, P>0.05). The statistical difference of mean ADC values, between benign and malignant nodules with b value of 800 s/mm2 [(1.61± 0.30) × 10-3 mm2/s and (1.44±0.29) × 10-3 mm2/s], was insignificant (t=1.76, P>0.05). ROC curve indicated that the ADC value of 1.98 × 10-3 mm2/s or higher was the cut-off value for differentiating benign from malignant cold thyroid nodules, with a sensitivity of 85.7%, and a specificity of 78.6%. Conclusions: The image quality is best with b value

The PKA signaling pathway is differentially activated by the expression of regulatory subunits 1 (R1) and 2 (R2), whose levels change during development, differentiation, and neoplastic transformation. Following the identification of gene mutations within the PKA regulatory subunit R1A (PRKAR1A) that cause Carney complex-associated neoplasms, several investigators have studied PRKAR1A expression in sporadic thyroid tumors. The PKA regulatory subunit R2B (PRKAR2B) is highly expressed in benign, as well as in malignant differentiated and undifferentiated lesions. PRKAR1A is highly expressed in follicular adenomas and malignant lesions with a statistically significant gradient between benign and malignant tumors; however, it is not expressed in hyperplastic nodules. Although the importance of PKA in human malignancy outcomes is not completely understood, PRKAR1A expression correlates with tumor dimension in malignant lesions. Additional studies are needed to determine whether a relationship exists between PKA subunit expression and clinical outcomes, particularly in undifferentiated tumors. In conclusion, the R1A subunit might be a good molecular candidate for the targeted treatment of malignant thyroid tumors. PMID:27321957

  7. Diagnostics, therapy and ecology of thyroid diseases

    International Nuclear Information System (INIS)

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

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

    International Nuclear Information System (INIS)

    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

    We report on an exceedingly rare lesion of the thyroid probably of a branchial cleft origin, which was not published in the world literature before. A 58-year-old woman underwent a total thyroidectomy for bilateral goiter. Grossly, there was one yellowish nodule sized 15 mm in the largest dimension found in the right lobe. Microscopically, the thyroid parenchyma showed signs of Hashimoto thyroiditis. The nodule in the right lobe was composed of a part of solid cell nests appearance, another part resembling a branchial cleft cyst, and a part resembling Warthin tumor. This lesion may belong to the histogenetically similar group of entities in the head and neck region which are derived from branchial cleft derivatives and which, under the inflammatory influence, have the ability to a cystic dilatation and proliferation of the epithelial component. The epithelium can afterwards become papillary and may undergo oncocytic transformation, thus gaining features that impart the resemblance of a Warthin tumor. Club members generally agreed with a submitted diagnosis of benign Warthin tumor of the thyroid. PMID:27438374

    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.

  17. Hepatic steatosis: A benign disease or a silent killer

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Steatosis is a common feature of many liver diseases, namely non-alcoholic steatohepatitis (NASH) and hepatitis C virus (HCV) infection, but the pathogenic mechanisms differ. Insulin resistance (IR), a key feature of metabolic syndrome, is crucial for NASH development, associated with many underlying genetically determined or acquired mitochondrial and metabolic defects and culminates to inflammation and progression to fibrosis. This may have potential implications for new drug therapy. In HCV-related disease, steatosis impacts both fibrosis progression and response to treatment. Steatosis in HCV-related disease relates to both viral factors (HCV genotype 3), and host factors (alcohol consumption, overweight, hyperlipidemia, diabetes). Among others, IR is a recognized factor. Hepatic steatosis is reported to be associated with disturbance in the signaling cascade of interferon and downregulation of its receptors. Thus, hepatic steatosis should not be considered a benign feature, but rather a silent killer.

    The detection of somatic mutations in indeterminate or follicular proliferation fine-needle aspiration cytologies (FNACs) is able to clarify only a subgroup of those FNACs. Therefore, further markers to differentiate this problematic FNAC category by the identification of mutation negative thyroid cancers and benign nodules are urgently needed. Our objective was to evaluate previously published miRNA markers and discover novel ones from all publicly available miRNA expression profiling data sets. By literature review and data repository search we gathered 3 data sets describing human miRNA expression profiles of follicular thyroid cancer (FTC) and follicular adenoma (FA) samples. Literature review summarized 27 previously published miRNAs, which were validated in the 3 available data sets. By means of uniform statistical analysis 6 further miRNAs were identified and tested in an independent, previously published microarray data set. Meta-analysis confirmed 7 out of 27 previously published, and 4 out of 6 de novo identified miRNAs. The low confirmation rate of previously published miRNA markers was induced by low numbers of samples in the analyzed studies and high false discovery rates that were higher than 0.2. Finally, miR-637, miR-181c-3p, miR-206, and miR-7-5p were discovered as de novo potential FTC markers and validated in at least one independent, previously published data set. Two out of these new identified miRNAs (miR-7-5p and miR-206) were validated by qPCR in an independent sample set of 32 FTC and 46 FA samples. Especially miR-7-5p was able to differentiate benign and malignant thyroid tumors in several datasets. PMID:24446156

  1. Nuclear medicine for diagnosis in benign diseases of the skeleton

    International Nuclear Information System (INIS)

    In summary, the lecture presents today's state of nuclear medical diganostics in benign bone disease, the radiopharmaceuticals, and the methods used. Besides the 99m-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.

    Laparoscopic surgery for benign and malignant pancreatic lesions has slowly been gaining acceptance over the past decade and is being introduced in many centres. Some studies suggest that this approach is equivalent to or better than open surgery, but randomized data are needed to assess outcomes. In this Review, we aim to provide a comprehensive overview of the state of the art in laparoscopic pancreatic surgery by aggregating high-quality published evidence. Various aspects, including the benefits, limitations, oncological efficacy, learning curve and latest innovations, are discussed. The focus is on laparoscopic Whipple procedure and laparoscopic distal pancreatectomy for both benign and malignant disease, but robot-assisted surgery is also addressed. Surgical and oncological outcomes are discussed as well as quality of life parameters and the cost efficiency of laparoscopic pancreatic surgery. We have also included decision-aid algorithms based on the literature and our own expertise; these algorithms can assist in the decision to perform a laparoscopic or open procedure. PMID:26882881

  3. Metaiodobenzylguanidine (MIBG) uptake in Parkinson's disease also decreases at thyroid

    International Nuclear Information System (INIS)

    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 123I-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)

    Full Text Available Background and Aims. The interactions between kidney and thyroid functions are well established: thyroid hormones are necessary for the maintenance of electrolyte and water homeostasis and kidney is involved in the regulation of thyroid hormones metabolism. The aim of our study was to estimate the prevalence of thyroid dysfunction in patients with diabetes mellitus and chronic kidney disease (CKD. Material and Method. 23 patients with diabetes mellitus and CKD in pre-dialysis phase were recruited for this study. All subjects were investigated with thyroid ultrasound and laboratory tests to determine thyroid function, including: serum triiodothyronine (T3, free thyroxine (free T4, thyroid-stimulating hormone (TSH and antithyroid peroxidase antibodies (ATPO. Results were compared with the same measurements in 21 patients with diabetes mellitus but without CKD. Results. The prevalence of goiter (52.17% vs. 19.04%, p<0.05, subclinical hypothyroidism (23.80% vs. 9.52%, p<0.05, hypothyroidism (8.69% vs. 4.76 %, p<0.05 and low T3 syndrome (23.80% vs. 0.00% p<0.05 were significant high in diabetic patients with CKD compared with patients with diabetes mellitus but without CKD. Conclusions. We observed high prevalence of thyroid morphology abnormalities and thyroid function disorders in diabetic patients with CKD. Low T3 syndrome and subclinical hypothyroidism are the most frequently thyroid function disorders in CKD patients.

    2015-02-01

    Thyroid eye disease is an auto-immune condition characterised by an acute inflammatory phase followed by a fibrotic phase, which sometimes leads to restricted eye movements and diplopia. Medical treatment with systemic steroids with or without orbital radiotherapy and immunosuppression can control the inflammatory response. Strabismus surgery should be carried out only after the inflammation is no longer active and after any decompression surgery. Surgery comprises recession of tight muscles using adjustable sutures so as to maximise the area of binocular single vision. There is debate as to whether adjustable sutures should be used for the inferior rectus muscle. Patients should be encouraged to have realistic expectations, as binocular single vision may not be achievable in all directions of gaze and lid retraction may be made worse by surgery.

    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.

    Background and Objectives: A renewed interest in the supra cervical approach to hysterectomy has created a cohort of patients with a retained cervix at risk of persistent symptoms requiring a subsequent trachelectomy. The objective of this study was to evaluate the efficacy of robotic trachelectomy after a previous supracervical hysterectomy. Methods: This is a retrospective chart review of women who had robotic trachelectomy after supracervical hysterectomy for benign gynecologic disease from January 2009 through October 2014. Results: Eleven patients underwent robotic trachelectomy for benign conditions during the observed period. Prior supracervical hysterectomy had been performed for pelvic pain (8/11, 73%), abnormal uterine bleeding (7/11, 64%), and dysmenorrhea (5/11, 45%). In 10 of 11 patients, the symptoms leading to robotic trachelectomy were the same as those leading to supracervical hysterectomy. The time from hysterectomy to recurrence of symptoms ranged from 0.5 to 26 months (median, 6), whereas the time interval from previous surgery to robotic trachelectomy ranged from 1 to 57 months (median, 26). Mean age and body mass index at robotic trachelectomy were 42 ± 5.4 years and 32 ± 6.1 kg/m2. Mean length of surgery was 218 ± 88 minutes (range, 100–405). There was 1 major postoperative complication involving bladder perforation and subsequent vesicovaginal fistula (VVF). Endometriosis was seen in 27% of pathologic specimens and cervicitis in another 27%; 45% showed normal tissue histology. In 6 (55%) cases, symptoms leading to trachelectomy resolved completely after surgery, and the other 5 (45%) patients reported a significant improvement. Conclusions: Although trachelectomy can be a challenging surgery, our experience suggests that the robotic approach may be a valuable means of achieving safe and reproducible outcomes. PMID:27493470

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

  18. Thyroid dysfunction after mantle irradiation of Hodgkin's disease patients

    International Nuclear Information System (INIS)

    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

    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

    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.

  5. Thyroid dysfunction after radiotherapy in children with Hodgkin's disease

    International Nuclear Information System (INIS)

    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

  6. Cervical removal at hysterectomy for benign disease. Risks and benefits.

    1993-10-01

    An assessment of the risks and benefits of total and subtotal hysterectomy for benign disease was performed using the published literature, including a MEDLINE search, on all studies dealing with hysterectomy and related topics from 1946 to 1992. The shift from subtotal to total hysterectomy occurred before cytologic screening was accepted. Currently, SIL is diagnosed by cytology, evaluated by colposcopy and treated preferentially with cone biopsy. Prophylactic removal of the cervix does not eliminate the risk of cancer: it may shift the risk to the vaginal epithelium. The cervix has a role in sexual arousal and orgasm, probably due to stimulation of the Frankenhauser uterovaginal plexus. Bladder and bowel dysfunction following total hysterectomy may be related to loss of nerve ganglia closely associated with the cervix. Increased operative and postoperative morbidity, vaginal shortening, vault prolapse, abnormal cuff granulations and oviductal prolapse are other disadvantages of total hysterectomy. The cervix is not a useless organ and should not be removed during hysterectomy without a proper indication. PMID:8263867

    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

    Materials and Methods: In this retrospective study, percutaneous biliary interventions were performed in fifteen children with a mean age of 10.2 years (range 14 days-14 years. Patients presented with jaundice (n=5 and/or cholangitis (n=10. Percutaneous transhepatic biliary drainage (PTBD performed in 10 patients, PTBD plus balloon dilation in 3, percutaneous cholecystostomy (PC in 1, PTBD following PC in 1. Results: All procedures were technically successful. No procedure-related mortality occurred in patients. Serum bilirubin levels returned to normal or near normal in ten of twelve cases. Preexisting cholangitis and acute cholecystitis resolved in all patients. Six patients underwent surgery following percutaneous management. Nine patients cured primarily with percutaneous interventions with no further treatment. Conclusion: Percutaneous biliary interventions can be performed effectively in benign diseases of children. It can be performed either as a primary treatment modality or as a bridge prior to surgery. In most of cases, percutaneous treatment is sufficient and unnecessary surgery is prevented.

    Thyroid nodules are a common clinical problem for surgeons. The clinical importance of nodules is the need to exclude thyroid cancer, which occurs in 5%-15% of patients. If fine needle aspiration cytology is positive, or suspicious for malignancy, surgery is recommended. During the past decade, with the tendency to develop smaller incisions, an endoscopic approach has been applied to thyroid surgery, called minimally invasive video-assisted thyroidectomy. This approach was immediately followed by other minimally invasive or scarless neck techniques, such as the breast approach, axillary-breast approach, and robot-assisted method. All these techniques follow the same principles of surgery and oncology. This review presents the current surgical management of the thyroid gland, including the surgical techniques and compares them by describing benefits and drawbacks of each one. PMID:22247619

    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

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.

  17. Thyroid effects

    International Nuclear Information System (INIS)

    Risk coefficients for thyroid disorders have been developed for both 131I 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 131I 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

    CONTEXT: Primary overt autoimmune hypothyroidism is often divided into primary idiopathic hypothyroidism with thyroid atrophy (Ord's disease) and hypothyroidism with goitre (Hashimoto's disease). OBJECTIVE: The aim of the present study was to characterize the two subtypes of disease. DESIGN AND...... SETTING: This was a population-based study identifying patients newly diagnosed with overt autoimmune hypothyroidism. PATIENTS: We prospectively identified all patients with incident overt autoimmune hypothyroidism in a Danish population cohort, and 247 patients were invited to join a comprehensive...... before hypothyroidism was diagnosed. CONCLUSIONS: In primary autoimmune hypothyroidism, thyroid volume follows a normal distribution. Cases with thyroid atrophy and goiter are only extremes within this distribution and do not represent separate disorders. However, patients with low vs. high thyroid...

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.

    Several studies found a higher prevalence of Autoimmune Thyroid Disease (ATD) in patients with Chronic Urticaria (CU). This relationship may be due to the possible autoimmune etiology in up to one third of the cases of Chronic Idiopathic Urticaria (CIU). However, the frequency of ATD ranged from 1.14% to 28.6%. The study began by determining whether there is an association between ATD and CU, in a population seen at the same clinic. We compared the frequency of anti-thyroid antibodies and thyroid dysfunction in 49 patients with CIU (group 1) and 112 controls (group 2). In order to support the result found, we studied the prevalence of CIU in 60 patients with ATD (group 3) and compared with 29 patients who had non-immune thyroid disease (NITD) (group 4). We did not find a statistical difference for the presence of anti-thyroid antibodies or thyroid dysfunction between groups 1 and 2 (12.24% x 9.82% and 12.24% x 7.14%, respectively). The same occurred for the presence of CIU among groups 3 and 4 (3.33% x 3.44%). In our study it was not possible to demonstrate a relationship between ATD and CIU, which means that different populations may present a higher or lower degree of association between these illnesses.

  1. Comparison of muscle-to-nodule and parenchyma-to-nodule strain ratios in the differentiation of benign and malignant thyroid nodules: Which one should we use?

    International Nuclear Information System (INIS)

    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

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

  4. Gallium scanning in differentiating malignant from benign asbestos-related pleural disease

    International Nuclear Information System (INIS)

    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

  5. Halo sign: useful CT sign for differentiating benign from malignant colonic disease

    International Nuclear Information System (INIS)

    AIM: To evaluate the halo sign for accurately distinguishing benign from malignant colonic wall thickening. MATERIALS AND METHODS: Computed tomography (CT) examinations of 92 patients (70 men; 22 women; mean age 57 years) with pathologically proven colonic wall thickening (51 benign and 41 malignant) were retrospectively reviewed in a blinded fashion. The affected segment was assessed for presence of the halo sign, degree and uniformity of thickness and density of the intramural stratum. RESULTS: The halo sign was present in 74.5% (38/51) patients with benign and 7.3% (3/41) patients with malignant bowel disease. The presence of the halo sign was 75.4% sensitive and 92.5% specific for benign bowel wall thickening. All 38 benign halos showed uniform, continuous stratification; only one of three malignant halos met the strict criteria for benign halo. CONCLUSION: The halo sign is a moderately sensitive and highly specific sign for distinguishing benign from malignant bowel wall thickening. However, it is not pathognomonic for benign disease. Detailed analysis of halo characteristics is necessary to improve the usefulness of this finding

The clinical importance of nodules is the need to exclude thyroid cancer, which occurs in 5%–15% of patients. If fine needle aspiration cytology is positive, or suspicious for malignancy, surgery is recommended. During the past decade, with the tendency to develop smaller incisions, an endoscopic approach has been applied to thyroid surgery, called minimally invasive video-assisted thyroidectomy. This approach was immediately followed by other minimally invasive or scarless neck techniques, such as the breast approach, axillary-breast approach, and robot-assisted method. All these techniques follow the same principles of surgery and oncology. This review presents the current surgical management of the thyroid gland, including the surgical techniques and compares them by describing benefits and drawbacks of

    To determine the prevalence of thyroid nodules discovered incidentally at ultrasonography and to reassess their significance. During a six-month period and using a high-frequency transducer, 1033 subjects with suspected breast disease underwent a prospective study of the thyroid. We determined the prevalence of thyroid nodules according to age, and the malignancy rate. Focal thyroid nodules were detected in 291 women (28.2%), their prevalence increasing with age (p<0.01). The nodules, totalling 337, were single in 260 cases (89.3%) and multiple in 31 (10.7%); 271 were less than 1 cm in diameter, 53 were 1-2 cm, and 13 were more than 2 cm (mean, 7.1(range, 2-34) mm); 126 (37.4%) were pure cysts, 62 (18.4%) were mixed, and 149 (44.2%) were solid. Of the 149 solid nodules, 139 were hypoechoic. Eighty women (with 106 nodules) underwent fine-needle aspiration bipsy, and 35 (with 45 nodules) underwent surgery. It was discovered, finally, that 29 women (2.8%) had 35 malignancies, of which 33 were papillary carcinomas and two were carcinomas which had metastasized from a breast malignancy. Eleven women (37.9%) had extrathyroidal invasion and 6 (20.7%) had cervical lymph node metastasis despite incidentaloma. The prevalence of incidentally found thyroid nodules was 28.2%. Since the malignancy rate of these was relatively high, at 10.4%, the clinical significance of this finding should be reassessed.

    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.

    Foci of ectopic thyroid tissue are uncommon. Most sites of thyroid ectopia are confined to the neck region. The presence of ectopic thyroid tissue outside the migration pathway of the primitive thyroid in other locations is exceptional. Given that any disease of the thyroid gland may also affect ectopic thyroid tissue, pathologists has to recognize benign or malignant conditions that may develop in the ectopic focus. We present the case of a 32-year-old woman with ectopic thyroid parenchyma in the adrenal gland. Clinically, postoperative thyroid ultrasound echography and computed tomography scans did not reveal any thyroid tumor. The ectopic tissue was a cyst bordered by mature follicular thyroid structures and was histologically benign, without the molecular alterations associated with malignant tumors of follicular cell derivation (BRAFV600E, N-RAS, H-RAS, K-RAS). Review of the literature reveals that adrenal ectopic thyroid tissue is nearly always cystic and has distinctive pathologic features. PMID:24997195

    Full Text Available Using immunohistochemistry, Fas/Apo-1 protein expression was investigated in thyroid cancers of 67 patients. Thyroid biopsies from twenty eight patients with benign thyroid diseases were also examined. The patients with thyroid cancer manifested a variable histology of the cancer, including 14 patients with follicular carcinoma, 48 with papillary carcinoma, 5 patients with medullary carcinoma. The benign thyroid disease involved nodular goitre in 11 patients and follicular adenoma in other 17 patients. The study aimed at examining immunohistochemical expression of Fas protein in order to determine whether the level of its expression correlated with histological diagnosis. In individual patients Fas expression was more prevalent in thyroid carcinomas as compared to benign tumors (p=0.001. A marked increase in Fas expression was found in papillary carcinoma, as compared to follicular and medullary carcinomas (p=0.02. In conclusion, Fas was significantly more frequently overexpressed in thyroid cancer, indicating its role in thyroid tumorigenesis.

    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.

    Thyroid disease is common, and the prevalence is rising. Traditional diagnosis and monitoring relies on thyroid stimulating hormone (TSH) levels. This does not always result in symptomatic improvement in hypothyroid symptoms, to the disappointment of both patients and physicians. A non-traditional therapeutic approach would include evaluation of GI function as well as a dietary history and micronutrient evaluation. This approach also includes assessment of thyroid peroxidase (TPO) antibodies, T3, T4, and reverse T3 levels, and in some cases may require specific T3 supplementation in addition to standard T4 therapy. Both high and low TSH levels on treatment are associated with particular medical risks. In the case of high TSH this is primarily cardiac, whereas for low TSH it is predominantly bone health. This article discusses these important clinical issues in more detail, with some practical tips especially for an approach to the "non-responders" to the current traditional therapeutic approach.

    International Nuclear Information System (INIS)

    Objective: To evaluate percutaneous vertebroplasty (PVP) treatment for benign and malignant vertebral lesions from a technique view. Methods: PVP was performed in 29 consecutive patients with 41 vertebrae involvement, including 23 vertebral metastatic neoplasms in 16 patients, osteoporotic fractures within 10 vertebrae in 7 patient, hemangiomas in 3 patients, and other lesions in 3 patients. PVP procedures were performed under the guidance of CT plus C-arm fluoroscopy or fluoroscopy only. Two to 8 ml of PMMA was injected per vertebra. Results: A techniques success of PVP was obtained in 97.56% (40/41). CR and PR were reached in 65.52% and 31.03% respectively in a follow-up of 2-10 months. No further or new vertebral compression occurred in all patients at the last follow-up. No major complications occurred in this series, except asymptomatic PMMA leak around vertebrae demonstrated by CT in 3 cases. Conclusions: PVP provides significant pain relief in both benign and malignant lesions. Procedure of PVP is safe and uncomplicated when performed under monitoring by C-arm X-ray machine in most cases. It is stressed that a proper use of PMMA is a key factor for PVP procedure

    The human body is colonized by a large number of microbes that are collectively referred to as the microbiota. They interact with the hosting organism and some do contribute to the physiological maintenance of the general good health thru regulation of some metabolic processes while some others are essential for the synthesis of vitamins and short-chain fatty acids. The abnormal variation, in the quality and/or quantity of individual bacterial species residing in the gastro-intestinal tract, is called “dysmicrobism”. The immune system of the host will respond to these changes at the intestinal mucosa level which could lead to Inflammatory Bowel Diseases (IBD). This inflammatory immune response could subsequently extend to other organs and systems outside the digestive tract such as the thyroid, culminating in thyroiditis. The goal of the present study is to review and analyze data reported in the literature about thyroiditis associated with inflammatory bowel diseases such as Ulcerative Colitis (UC) and Crohn’s Disease (CD). It was reported that similarities of some molecular bacterial components with molecular components of the host are considered among the factors causing IBD through an autoimmune reaction which could involve other non-immune cell types. The axis dysmicrobism-IBD-autoimmune reaction will be investigated as a possible etiopathogenic mechanism to Autoimmune Thyroiditis. If such is the case, then the employment of specific probiotic strains may represent a useful approach to moderate the immune system. PMID:26122213

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

    Patients and Methods: The presented data refer to a retrospective univariant examination of 67 patients, which have been treated for IPP with soft X-rays in the Dermatological Clinic of the Technical University of Munich between 1990 and 1995. The aim of the study was to examine, how far a progression of the disease can be stopped with soft X-rays and how the pain symptomatic is reduced. Results: In 58 of 67 examined patients (86.6%) a progression of the disease could be stopped. 25 out of 67 patients (37.3%) complained of pain before therapy. This symptomatic mostly improved totally in 21 patients (84% of the patients with pain). A complete or partial dissolution of the indurations was to be noticed in 41 of 70 indurations (58.6%). In 23 of 60 patients (38.3%) an improvement or totally regression of the deviation was observed. It could be shown that therapeutic outcome significantly correlates to a shorter duration of anamnesis (p < 0.05), smaller plaque size (p < 0.025) and a tendency to lower age of the patients. Conclusion: Radiotherapy of Morbus Peyronie is extremely effective and has a low rate of side effects. (orig.)

  1. Detection of extensive abdominal lymphadenopathy in benign diseases by CT scanning

    International Nuclear Information System (INIS)

    Abdominal lymphadenopathy when detected on CT or US is invariably equated with lymphoma or metastatic disease. However, there is a small incidence of substantial abdominal lymphadenopathy secondary to benign diseases. The reports of 21,000 consecutive CT examinations were reviewed for the presence of extensive abdominal lymphadenopathy. In a total of 160 cases, lymph node enlargement was found, with lymphoma having the highest incidence (45%). Nine cases (6%) were secondary to benign diseases, including sarciodosis, tuberculosis, mastocytosis, necrotizing granulomatous lymphadenopathy secondary to Crohn disease, chronic lymphoproliferative disorder, rhemuatoid arthritis, peritonitis, inflammatory lymphadenitis, and idiopathic lymphadenopathy due to fibrosis. These entities, along with other benign processes, should be considered in the differential diagnosis of abdominal lymphadenopathy in the appropriate clinical setting, particularly if the patient does not have a primary carcinoma

    The most common thyroid diseases during pregnancy are hyper- and hypothyroidism and their variants including isolated hypothyroxinemia (hypo-T4), autoimmune thyroid disease (AITD) and different types of goiter. AITD represents the main cause of hypothyroidism during pregnancy ranging in prevalence between 5 and 20% with an average of 7.8%. The incidence of isolated hypo-T4 is about 150 times higher compared to congenital hypothyroidism. Prevalence of Graves' disease (GD) ranges between 0.1% and 1% and the Transient Gestational Hyperthyroidism Syndrome between 1 and 3%. Thyroid stimulating hormone (TSH) is a sensitive marker of thyroid dysfunction during pregnancy. Normal values have been modified recently with a downward shift. Thus, the upper normal range is now considered to be 2.5 mUI/mL in the first trimester and 3.0 mUI/mL for the remainder of pregnancy. Most studies have shown that children born to women with hypothyroidism during gestation had significantly lower scores in neuropsychological tests related to intelligence, attention, language, reading ability, school performance and visual motor performance. However, some studies have not confirmed these findings. On the other hand, multiple retrospective studies have shown that the risks of maternal and fetal/neonatal complications are directly related to the duration and inadequate control of maternal thyrotoxicosis. The latter is associated with a risk of spontaneous abortion, congestive heart failure, thyrotoxic storm, preeclampsia, preterm delivery, low birth weight and stillbirth. Despite the lack of consensus among professional organizations, recent studies, which are based on sophisticated analyses, support universal screening in all pregnant women in the first trimester for thyroid diseases.

    With the advent of better thyroid function tests, a tumor marker, and fine-needle aspiration, the role of thyroid imaging studies in the evaluation of the patients with thyroid disease has diminished. Although multimodality thyroid imaging had improved our understanding of thyroid disease, current indications for thyroid imaging are the solitary or dominant thyroid nodule, an upper mediastinal mass, differentiation of hyperthyroidism, detection and staging of postoperative thyroid cancer, neonatal hypothyroidism, thyroid developmental anomalies, and the thyroid mass post-thyroidectomy for benign disease. To provide optimal, cost-effective, care for the thyroid patient, the physician must understand the advantages and disadvantages of each imaging modality--scintigraphy, real-time sonography (RTS), computed tomography, and magnetic resonance--in specific clinical settings. Similarly, preoperative noninvasive localization of hyperfunctioning parathyroid tissue in patients with primary hyperparathyroidism undergoing their initial neck exploration usually is not warranted. In this situation, the best localization procedure is to enlist the services of an experienced parathyroid surgeon. However, if this is not feasible because of local constraints, both sestamibi methoxy isobutyl isonitrile (MIBI) scintigraphy and magnetic resonance imaging (MRI) provide excellent localization (< 90%) of juxta-thyroidal and ectopic parathyroid adenomas. Hyperplastic glands are more difficult to detect because of their smaller size, and tandem studies (MIBI and MRI) should provide higher sensitivity before initial exploration, especially in patients with ectopic glands. In patients with persistent or recurrent disease, multimodality imaging with MIBI, MR, computed tomography and RTS in a sequential fashion is warranted to optimize two-test, site-specific localization.

    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. PMID:26486481

    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.

    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.

    Full Text Available Autoimmune thyroid disease may occasionally associate with unspecific neurological symptoms, which are more commonly insidious, include cognitive or behavioural symptoms, and may associate with tremor, myoclonus, or ataxia. We report a 61-year-old female patient who presented with chronic headache, insidious mood, and cognitive disturbance which evolved in a few months to dementia associated with exuberant limb myoclonus. Diagnostic workup revealed high anti-thyroid peroxidase antibody titers and an inflammatory CSF profile, and it was negative for other possible etiologies. Treatment with steroids induced significant improvement. The diagnosis of encephalopathy associated with autoimmune thyroid disease is still controversial given the fact that the clinical presentation and diagnostic workup are unspecific, the pathophysiology is still undetermined, and the diagnosis is mostly of exclusion. No direct correlation is found between anti-thyroid antibody titers and clinical presentation, and it is currently speculated that other still unrecognized antibodies may be responsible for this clinical entity. It is extremely important to recognize this entity because it is potentially treatable with immunotherapies. It is also increasingly recognized that clinical improvement with first-line treatment with steroids may be absent or incomplete, and other immunotherapies as immunosuppressants, intravenous immunoglobulin, or plasma exchange must be attempted in the clinical suspicion of EEAT.

    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

    2015-01-01

    Full Text Available A 44-year-old female presented with a two-month history of a neck mass, sore throat, hoarseness, and intermittent dysphagia. Examination revealed a “woody” hard swelling arising from the right lobe of the thyroid. Clinically this was felt to be classical Riedel’s thyroiditis (RT. Thyroid ultrasound showed a diffusely enlarged, low echogenicity thyroid with a multinodular goitre. An abnormal nodule extending across the isthmus was noted. Following a nondiagnostic fine needle aspiration, an open core biopsy was performed. This showed dense sclerotic fibrosis punctuated by nodular mononuclear inflammatory cells, which obscured follicular epithelial cells consistent with a fibrosing thyroiditis (Riedel’s thyroiditis. A biopsy of pretracheal lymph nodes showed a sclerotic process throughout the lymph nodes and nests of epithelium bands with squamous differentiation obscured by a fibrous process. These findings raised the differential diagnosis of diffuse sclerosing variant of papillary thyroid carcinoma (DSV-PTC with metastasis to lymph nodes. A total thyroidectomy and pretracheal lymph node dissection were performed. The final histological diagnosis was DSV-PTC. When managing a patient with presumed RT it is important to consider malignancy in the differential. DSV-PTC is one of the more aggressive forms of thyroid cancer but with early diagnosis and appropriate treatment patients may have excellent outcomes.

  16. Current trend of research on 131I therapy for thyroid diseases

    International Nuclear Information System (INIS)

    At present time, there are two current trends of research on 131I therapy for thyroid diseases. The first is extension of the application on the field of thyroid diseases. Formerly, the authors use the 131I 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 131I more widely, because it is really safe, easy and cheaper than others. The second trend is using 131I 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

    To characterize the nature of thyroid peroxidase (TPO) autoantibodies present in the sera of patients with autoimmune thyroid disease, we cloned three IgG1/kappa Fab fragments which bind 125I-TPO. This was accomplished by the molecular cloning and expression in bacteria of IgG gene fragments from B cells infiltrating the thyroid of a patient with Graves' disease. The three Fab fragments (SP2, SP4, and SP5) are coded for by a common heavy chain (VH1, D, JH3) and three related, but different, l...

  18. Anti-thyroid peroxidase antibodies: Its effect on thyroid gland and breast tissue

    Directory of Open Access Journals (Sweden)

    Sabitha Kandi

    2012-01-01

    Full Text Available Thyroid peroxidase (TPO is a key enzyme in the synthesis of thyroid hormone. TPO is involved in thyroid hormone synthesis (organification and coupling reactions. TPO is a major antigen corresponding to thyroid-microsomal autoantibodies. Anti-TPO auto antibodies are very important to diagnose autoimmune thyroid diseases and also in estimating its clinical course. Autoimmune thyroid disease is detected mostly by measuring circulating antibodies to thyroglobulin which is uncommon measurement of antibodies to TPO that gives reliable information about autoimmune thyroid disease. Eighty percent of Grave′s disease patients have high levels of antiTPO antibodies. About 4% of subclinical hypothyroid patients with positive TPO antibodies develop clinical hypothyroidism. There is always a controversy on the relationship between breast cancer and thyroid disorders. As these tissues, i.e., breast and thyroid, originate embryologically from the same type of cells, hypothyroid/hyperthyroid females are more prone to develop benign or malignant breast tumors. The studies on breast cancer patients indicate increased thyroid disorders in breast cancer patients, most commonly Hashimoto′s thyroiditis accounts to increased thyroid disorders in these patients. This is independent of hormonal receptor status of the patient. These findings suggest the usefulness of screening for thyroid disease in any patient with breast cancer.

    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.

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

    International Nuclear Information System (INIS)

    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.)

    2015-01-01

    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. PMID:25932387

    International Nuclear Information System (INIS)

    To determine the frequency of autoimmune thyroid disease in diagnosed cases of chronic urticaria (CU) and the association between hypothyroidism and chronic urticaria if any. Study Design: Non-interventional, descriptive study. Place and Duration of Study: Department of Physiology, Dow University of Health Sciences, Karachi, from December 2004 to January 2006. Methodology: The patients were selected from Department of Dermatology and Medical Units of Civil Hospital, Jinnah Postgraduate Medical Centre, the Aga Khan Hospital and community clinics. A total number of 60 patients were enrolled in this study. In all patients, serum antithyroid autoantibodies (anti thyroglobulin and anti microsomal/thyroperoxidase), thyroid profile (serum TSH, T3 and FT4), complete blood count, erythrocyte sedimentation rate and IgE levels were carried out. The proportions were compared using chi-square test with significance at p < 0.05. Results: Forty seven (78%) patients were found to have chronic urticaria (history and laboratory reports). Out of 47 patients with diagnosis of CU, elevated titres of anti thyroglobulin (TGA) and anti microsomal antibodies (TMA) were found to be present in 20 (42.6%) and 27 (57.4%) patients respectively. Serum TSH level (thyroid stimulating hormone) was increased and T3, FT4 were decreased in 20 (42.6%) patients (p < 0.001). A total number of 20 (42.5%) patients were found to be hypothyroid with chronic urticaria of greater than 6 weeks duration. Conclusion: This study shows a statistically significant association between hypothyroidism and chronic urticaria. Full thyroid profile (serum thyroid autoantibodies, serum TSH, T3 and FT4) is highly recommended in patients with diagnosis of chronic urticaria. (author)

On the other hand, 184 patients with coeliac disease were subjected to thyroid biochemical (thyroid stimulating hormone and free thyroxine) and thyroid serological tests (thyroglobulin and thyroid peroxidase antibodies).RESULTS: Of 104 patients with Hashimoto's thyroiditis, sixteen (15%) were positive for coeliac serology and five patients with documented villous atrophy were diagnosed with coeliac disease (4.8%; 95% CI 0.7-8.9). HLA-DQ2 (and/or -DQ8) was present in all the five and 53 patients with Hashimoto's thyroiditis (50%; 95% CI 43-62). Of 184 patients with coeliac disease, 39 (21%) were positive for thyroid serology. Based on thyroid biochemistry, the 39 patients were subclassified into euthyroidism in ten (5%; 95% CI 2-9), subclinicalhypothyroidism in seven (3.8%; 95% CI 1.8-7.6), and overt hypothyroidism (Hashimoto's thyroiditis) in 22 (12%; 95% CI 8-16). Moreover, four patients with coeliac disease had Graves' disease (2%; 95% CI 0.8-5) and one patient had post-partum thyroiditis.CONCLUSION: The data from a Dutch population confirm the association between Hashimoto's thyroiditis and coeliac disease. Screening patients with Hashimoto's thyroiditis for coeliac disease and vice versa is recom mended.

    Vitamin D deficiency (levels lower than 20 ng/ml) is becoming a global health problem, since it is increasingly represented even among healthy subjects. Vitamin D, as an environmental factor, is involved in many biological processes, like perception of chronic pain and response to infections. In recent years, evidence has emerged pointing to an involvement of vitamin D in the development of many autoimmune diseases, and a severe vitamin D deficiency has been especially demonstrated in patients affected with autoimmune thyroid disease (AITD). Low levels of vitamin D were found associated with antithyroid antibody presence, abnormal thyroid function, increased thyroid volume, increased TSH levels, and adverse pregnancy outcome in women with AITD. Vitamin D mediates its effect through binding to vitamin D receptor (VDR), which is harbored on many human immune cells, and in this way is able to modulate immune cells activity, triggering both innate and adaptive immune responses. As VDR gene polymorphisms were found to associate with AITD, the evidence links vitamin D deficiency to AITD either through gene polymorphism or by environmental factors (lack of dietary uptake and sun exposure). Vitamin D supplementation may be offered to AITD patients, but further research is needed to define whether it should be introduced in clinical practice. PMID:25407646

    Standard imaging of pancreas is generally obtained by computed tomography and magnetic resonance imaging. However endoscopic ultrasound (EUS) has become an indispensable tool for the diagnosis of various pancreatic diseases. Because of the close proximity of the EUS probe to the pancreas, EUS provides excellent images of the pancreas. In this review, we discuss the role of EUS in the clinical management of patients with benign pancreatic diseases, i.e., various forms of pancreatitis.

    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 tumor cells, can be identified from OCT and OCM images and are clearly differentiable from normal or benign 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.

    Full Text Available Backgrounds and Objectives: Today we are witnessed a growing number of minimally invasive surgical techniques for different diseases. Laparoscopic colon surgery as a minimally invasive surgery is currently growing in treatment of malignancies after proving his place in the treatment of benign diseases. We compare in this study results of laparoscopic colorectal surgery with open surgery. Methods: 36 laparoscopic colon resections performed for benign disease were compared to 36 open colon resections with respect to operating times, length of hospital stay, estimated blood loss, days until first postoperative bowel movement, and complications.   Results: The laparoscopic colon resection group had decreased length of stay, less blood loss, earlier return of bowel function, and an equivalent number of complication. Duration of surgery was higher in the laparoscopic group.   Conclusion: The use of laparoscopic colon surgery for benign disease not only affords the patient the advantage of the laparoscopic approach, but also allows the surgeon to gain experience for laparoscopic colon surgery in malignant disease.

    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.

    The authors present an update version of the indications for radiotherapy in the management of benign diseases. This is based on available randomized trials and recent international meetings. Validated indications remain the prevention of resected heterotopic bone ossifications, keloids scars and pterygium and also treatment of arteriovenous malformations; the place of radiotherapy for malignant exophthalmia is more and more restricted. Randomized trials have demonstrated the efficacy of endo-brachytherapy in the prevention of restenosis after angioplasty but the use of embedded stent has replaced this indication. Macular degeneration is no more an indication of radiotherapy. Quality requirements for radiotherapy are identical for benign or malignant indications. (author)

  6. The effectiveness of iodine prophylaxis and frequency of thyroid enlargement (thyroid goiter) and clinical diagnosis of thyroid diseases in inhabitants of Szczecin's region after Chernobyl accident

    International Nuclear Information System (INIS)

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

  7. The effect of chemoradiation therapy on pituitary-thyroid system function in children suffering Hodgkin's disease

    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

  8. Thyroid

    International Nuclear Information System (INIS)

    In vivo thyroid function testing is conducted with isotopes of iodine, the rate-limiting substrate for thyroid hormonogenesis, or with pertechnetate, an anion which the thyroidal follicular cells will concentrate or trap similarly to iodide, but will not organify. The physical characteristics of these isotopes, their advantages or indications, their disadvantages, and the average radiation dose to the thyroid in the infant, child, and adult are reviewed. The latter is expressed as estimated dose in rads per microcurie administered assuming an uptake of 27 percent and a biological half-life of 68 days. For many years the standard isotope for thyroid studies has been 131I. This isotope, however, has the disadvantage of a high radiation dose to the gland, especially in infants and children. Furthermore the high-energy gamma ray (364 keV) requires low-efficiency, thick septal collimators for scanning. More recently 125I, 123I, and 99/sup m/Tc-pertechnetate have been used. (auth)

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

    We evaluated the characteristics of the benign and malignant nodules on transrectal ultrasound in diagnosis of prostatic disease. Histologic examination of the trans perineal prostatic biopsy of the total 47 cases resulted in 19 cases of BPH, 8 cases of prostatic cancer, and 20 cases of normal prostatic tissue group. The hypoechoic mass in peripheral zone on TRUS had high possibility of prostatic carcinoma and the isoechoic or mixed echogenic mass in central gland had high possibility of benign lesion. Hypoechoic haloes around nodules and cysts were noted in BPH and normal prostatic tissue group, that were compatible with benign lesion. The mean value of PSA was 12.0 ng/ ml in BPH, 8.5 ng / ml in normal prostatic tissue group, and 65.6 ng / ml in prostatic cancer, which was very high in prostatic cancer. Between BPH and normal prostatic tissue group, there was no demonstrable difference in location of nodule, pattern of calcification, and echogenicity of the nodules on TRUS. The size of prostatic gland was relatively smaller and mean value of PSA was lower in normal prostatic tissue group, compared with in BPH. In conclusion, the location of the nodules and PSA value are considered to be important in differentiation of the benign and malignant prostatic nodules

  15. The diagnostic value of Th1/Th2 cell cytokine and thyroid autoantibody on autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    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)

  16. The role of octreoscan in thyroid eye disease.

    1999-05-01

    Until recently there was no imaging technique available which could demonstrate pathological changes in orbital tissues and could be regarded as a reliable measure of inflammation in thyroid eye disease (TED). Pentetreotide (a synthetic derivative of somatostatin) labelled with 111In has been used to localize tumours which possess surface or membrane receptors for somatostatin in vivo using a gamma camera (1). This technique visualizes somatostatin receptors in endocrine-related tumours in vivo and predicts the inhibitory effect of the somatostatin analogue octreotide on hormone secretion by the tumours (1). By applying 111In-DTPA-d-Phe octreotide scintigraphy (octreoscan), accumulation of the radionuclide was also detected in both the thyroid and orbit of patients with Graves' disease (2-4). If peak activity in the orbit 5h after injection of radiolabelled octreotide is set at 100%, a decrease to 40+/-4% is found at 24h, significantly different from the decrease in blood pool radioactivity, which is 15+/-4% at 24h. Accumulation of the radionuclide is most probably due to the presence in the orbital tissue of activated lymphocytes bearing somatostatin receptors (5). Alternative explanations are binding to receptors on other cell types (e.g. myoblasts, fibroblasts or endothelial cells) or local blood pooling due to venous stasis by the autoimmune orbital inflammation.

    Full Text Available Introduction: Among endocrine disorders commonly encountered in pediatric age group, thyroid diseases are more frequent. Congenital hypothyroidism is one of the major problems in this age with worldwide incidence of 1:3000-4000 live birth and in India it is 1:2500-2800. Objectives: The aim of this study is to know the prevalence of thyroid diseases in newborn and children by hormonal evaluation. Methodology: We have studied 50 children suspected of having signs and symptoms of thyroid diseases. Hormonal evaluation was done by the estimation of serum TSH, T3 and T4. Results: Out of total 50 children, 16 were detected with abnormal hormone level and diagnosed having thyroid diseases. Out of 16 affected children, 4 had congenital hypothyroidism (25%, 6 had subclinical or acquired hypothyroidism (37.5%, 3 had autoimmune thyroiditis (18.75% and 3 had goiter with graves disease (18.75%. Conclusion: Congenital hypothyroidism is one of the major preventable thyroid disease if diagnosed early. Other thyroid diseases commonly seen in pediatric age are subclinical hypothyroidism, autoimmune thyroiditis, goiter and rarely hyperthyroidism. [Natl J Med Res 2013; 3(4.000: 367-370

    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.

  19. Preoperative localization and minimally invasive management of primary hyperparathyroidism concomitant with thyroid disease

    The coexistence of thyroid diseases with primary hyperparathyroidism (PHPT) can present a challenge in the clinical diagnosis and management for these patients. This study aims to determine the frequency of coexisting thyroid gland lesions in a consecutive series patients with PHPT, and to analyze the clinical features, diagnosis and treatment of these patients. Twenty-two cases of a total of 52 PHPT patients who had synchronous thyroid and parathyroid pathology were surgically managed in this study.Thirteen patients had ipsilateral thyroid nodules, and 9 patients had thyroid nodules in contralateral or bilateral side. Seven patients underwent direct parathyroidectomy and hemithyroidectomy via a mini-incision (about 3 cm), while other 15 procedures were converted to Kocher incision. Seventeen nodular goiter (32.7%), 2 thyroiditis (3.8%), 2 thyroid adenoma (3.8%) and 1 thyroid carcinoma (1.9%) coexisting with parathyroid adenoma were pathologically diagnosed. The sensitivity of preoperative ultrasonography (US) and methoxy-isobutyl-isonitrile (MIBI) scintigraphy for parathyroid lesions was 63.6% and 85.7%; and the overall positive predictive values for MIBI and US were 100% and 95.5% respectively. A high incidence of thyroid diseases that coexisted with PHPT in literatures was briefly reviewed. Our study illustrated the need for clinical awareness of concomitant PHPT and thyroid disease. A combination of US, computed tomography (CT) and MIBI scintigraphy would be recommended for preoperative localization of enlarged parathyroid adenoma and for evaluation of thyroid lesions. Synchronous treatment of associated thyroid abnormalities is desirable, and open minimally invasive surgical approach with additional resection of isolated ipsilateral thyroid nodules is possible in some of these patients.

  20. Does thyroxine suppression therapy help to rationalize surgery in benign euthyroid nodules?

    International Nuclear Information System (INIS)

    Nodular thyroid disease is a common endocrine problem. Most thyroid nodules are benign hyperplastic lesions, but 5-20% may be a true neoplasm. It is important to differentiate a benign from a malignant nodule early as the approach to treatment in the two is radically different. Early institution of medical management in a benign nodule may obviate the need for surgery. Purpose of the Study: The present work aims to study the efficacy of thyroxine suppression in the management of benign thyroid nodules. Materials and Methods: A prospective study on patients presenting with thyroid nodule was undertaken. The diagnostic work-up included a clinical evaluation, thyroid function tests, thyroid scintigraphy and fine needle aspiration cytology. Based on the investigations, patients were segregated in Group A (toxic nodular goiter), Group B (benign euthyroid nodule) and Group C (malignant nodule). Group A patients were managed with antithyroid drugs and radioiodine and Group C patients were managed surgically. Group B patients were put on thyroxine suppression. Patients who failed to show reduction in size of the nodule at 18 months were treated surgically. Conclusion: The response rate of benign euthyroid nodule to thyroxine suppression was 76% in the present study. (author)

  3. 99mTc-sestamibi thyroid uptake in euthyroid individuals and in patients with autoimmune thyroid disease

    International Nuclear Information System (INIS)

    We investigated the biokinetics of 99mTc-sestamibi in the thyroid of euthyroid volunteers (EVs) and in patients with autoimmune thyroid diseases and determined the best time interval between 99mTc-sestamibi injection and calculation of uptake. Forty EVs, 30 patients with Graves' disease (GD), 15 patients with atrophic Hashimoto's thyroiditis (AHT) and 15 patients with hypertrophic Hashimoto's thyroiditis (HHT) underwent 99mTc-sestamibi thyroid scintigraphy. Dynamic images were acquired for 20 min, and static images were obtained 20 min, 60 min and 120 min post injection. Five-, 20-, 60- and 120-min uptake, time to maximal uptake (Tmax) and T1/2 of tracer clearance were calculated. Thyroid hormones and antibodies were measured. 99mTc-pertechnetate uptake was investigated in GD patients. Tmax was approximately 5 min in all four groups. The mean T1/2 value for EVs was similar to the GD value and lower than the HHT and AHT values. The mean (±SD) 5-min uptake was 0.13% (±0.05%) for EVs. The 5-min uptake in GD was higher than that in EVs(P99mTc-pertechnetate uptake (r=0.68). Uptake in HHT was higher than that in AHT (P=0.0003) and EVs (P=0.002). Uptake in AHT was lower than uptake in EVs (P=0.0001). Five minutes is the optimal time interval between 99mTc-sestamibi injection and calculation of thyroid uptake. Five-minute uptake differentiates euthyroid individuals from GD patients. There is a high correlation between 99mTc-sestamibi and 99mTc-pertechnetate uptake in GD. The reduced 99mTc-sestamibi uptake in AHT patients is probably due to glandular destruction and fibrosis. Inflammatory infiltrate and high mitochondrial density in thyrocytes possibly explain the increased uptake in GD and HHT. (orig.)

  4. Malignant and benign diseases of the breast in 41 male patients: mammography, sonography and pathological correlations

    International Nuclear Information System (INIS)

    Aim: The goal of our study was to evaluate findings in mammography and sonography in male patients with pathohistologically proven diseases of the breast. Material and Methods: Mammographies and sonographies, which were obtained in 41 male patients in a 6-year period, were retrospectively evaluated in accordance with the BI-RADS trademark classification. Results: Histologically 13 carcinomas, 21 gynecomastias, 3 pseudogynecomastias, 2 epithelial inclusion cysts and 2 other benign lesions were diagnosed. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of mammography in differentiation of benign versus malignant disease were 92%, 89%, 80%, 96% and 90%, respectively. Additional sonography did not change these results. However, sonography increased diagnostic confidence in 18.2% (2/11) of suspicious lesions. Conclusion: In our study the invasive ductal carcinoma of male patients was a predominantly lobulated, ill-defined lesion in mammography and sonography. The differentiation of carcinoma to pseudogynecomastia and diffuse or dendritic gynecomastia was securely feasible. However, we could not reliably distinguish between carcinoma and some benign mass lesions. In cases of mammographically diagnosed masses or unclear mammography, additional sonography should be performed to increase the diagnostic confidence. (orig.)

    Full Text Available High concentrations of serum pancreatic enzymes in asymptomatic subjects are not just an occasional laboratory finding but are of clinical interest as they raise questions about whether or not to conduct investigational procedures and what kinds. Frequently, these questions come from general practitioners and include assays for amylase and/or (though less frequently lipase in routine blood tests. The main question is whether asymptomatic pancreatic hyperenzymemia should be considered a benign syndrome without clinical significance or a biochemical sign of a subclinical disease including, in particular, pancreatic disease.

    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

  10. Huge Benign Ovarian Cystic Teratoma in a Patient with a History of Hansen’s Disease

    2014-01-01

    Full Text Available Mature ovarian cystic teratomas are common benign ovarian neoplasm derived from germ cells. With increasing availability of ultrasound services even in developing countries, the diagnosis of benign ovarian tumour is made earlier and the size of the ovarian tumour at diagnosis is relatively small. It is unusual to find an ovarian cystic teratoma larger than 10 cm. We report a huge mature ovarian cystic teratoma in a multipara with a history of Hansen’s disease. We conclude that, in circumstances where women have restricted access to health care, the unusual finding of mature ovarian cystic teratoma larger than 10 cm is possible due to delayed presentation for diagnosis and treatment.

    More than 10% of postmenopausal women in the United States receive thyroid hormone replacement therapy and up to 20% of these women are over-replaced inducing subclinical hyperthyroidism. Because hyperthyroidism and post menopausal osteoporosis overlap in women of advancing age, it is urgent to understand the effect of thyroid hormone excess on bone. We can now provide results that not thyroid hormones but also TSH itself has an equally important role to play in bone remodeling. PMID:18083940

    Screening for thyroid disease in pregnancy remains a contentious issue. This review presents these diverging views and discusses their reasons as well as the relevant facts. The final aim is to establish the information gaps and limitations - technological or otherwise - which still need to be eliminated in order to settle the debate conclusively. The prevalence of the more common thyroid dysfunctions that occur in and after pregnancy is discussed. The subsequent impact of these disorders on mother and offspring is also described. Special focus is placed on the benefits and setbacks of currently available and newly proposed investigations, which assay serum hormone levels, serum autoantibody levels, and/or use clinical data. It is pointed out that the relevance of screening varies from one region of the world to the other, based on the content of iodine and selenium in food and water. The review then discusses the current major arguments for and against screening, as well as recommendations and proposed alternatives. PMID:24051947

    To investigate the relationships between lymphocyte subsets and thyroid function, peripheral blood lymphocytes were analysed with cell surface antigens of activated (HLA-DR+) T, helper T (CD4+ 2H4-, CD4+ 4B4+) and suppressor-inducer T (CD4+ 2H4+, CD4+ 4B4-) cells subsets in 56 patients with Graves' disease, 16 patients with Hashimoto's thyroiditis, 7 patients with typical subacute thyroiditis and 2 patients with the thyrotoxic phase of autoimmune thyroiditis. Both patients with Graves' disease and Hashimoto's thyroiditis had increased percentages of HLA-DR+ T (Ia+ CD3+) cells as well as HLA-DR+ helper-inducer T (Ia+ CD4+) cells, which seemed to be independent of treatments. The percentage of HLA-DR+ suppressor-cytotoxic T (Ia+ CD8+) cells was increased in euthyroid or hypothyroid patients with Graves' disease following treatment, but was normal in hyperthyroid patients. The percentages of Ia+ CD4+ cells and Ia+ CD8+ were also increased in patients with thyroiditis, whereas these abnormal values normalized in the remission phase. These findings suggest that an increase in Ia+ CD4+ cells characteristically occurs during immune system activation in patients with hyperthyroid Graves' disease, Hashimoto's thyroiditis and the thyrotoxic phase of subacute thyroiditis, whereas the activated CD8+ cells in Graves' disease are induced by antithyroidal therapy.

    2015-01-28

    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.

  4. Simultaneous occurrence of Graves’ disease in eutopic and ectopic thyroid tissues: A case report and review of literature

    International Nuclear Information System (INIS)

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

  5. Regulation mechanisms of pituitary-thyroid axis in normal subjects and patients with Graves' disease

    International Nuclear Information System (INIS)

    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 T4 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 FT4. In conclusion, an individual patient may have a different set point concerning the regulatory mechanism of the pituitary-thyroid axis, and the persistence of the hyperthyroid state would seem to have caused some reversible dysfunction of the pituitary gland.

    Full Text Available Introduction. Recombinant human thyroid stimulating hormone (rhTSH is approved for preparation of thyroid remnant ablation with radioactive iodine (RAI in low risk patients with well differentiated thyroid cancer (DTC. We studied the safety and efficacy of rhTSH preparation for RAI treatment of thyroid cancer patients with nodal metastatic disease. Methods. A retrospective analysis was performed on 108 patients with histopathologically confirmed nodal metastatic DTC, treated with initial RAI between January 1, 2000, and December 31, 2007. Within this selected group, 31 and 42 patients were prepared for initial and all subsequent RAI treatments by either thyroid hormone withdrawal (THW or rhTSH protocols and were followed up for at least 3 years. Results. The response to initial treatment, classified as excellent, acceptable, or incomplete, was not different between the rhTSH group (57%, 21%, and 21%, resp. and the THW group (39%, 13%, and 48%, resp.; P=0.052. There was no significant difference in the final clinical outcome between the groups. The rhTSH group received significantly fewer additional doses of RAI than the THW group (P=0.03. Conclusion. In patients with nodal-positive DTC, preparation for RAI with rhTSH is a safe and efficacious alternative to THW protocol.

  7. Thyrotropin - Binding Inhibiting Immunoglobulin (TBII) in Patients with Autoimmune Thyroid Diseases

    International Nuclear Information System (INIS)

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

    In DNA from prostate tumors, methylation patterns in gene promoter regions can be a biomarker for disease progression. It remains unclear whether methylation patterns in benign prostate tissue-prior to malignant transformation-may provide similar prognostic information. To determine whether early methylation events predict prostate cancer outcomes, we evaluated histologically benign prostate specimens from 353 men who eventually developed prostate cancer and received "definitive" treatment [radical prostatectomy (58%) or radiation therapy (42%)]. Cases were drawn from a large hospital-based cohort of men with benign prostate biopsy specimens collected between 1990 and 2002. Risk of disease progression associated with methylation was estimated using time-to-event analyses. Average follow-up was over 5 years; biochemical recurrence (BCR) occurred in 91 cases (26%). In White men, methylation of the APC gene was associated with increased risk of BCR, even after adjusting for standard clinical risk factors for prostate cancer progression (adjusted hazard ratio (aHR) = 2.26; 95%CI 1.23-4.16). APC methylation was most strongly associated with a significant increased risk of BCR in White men with low prostate specific antigen at cohort entry (HR = 3.66; 95%CI 1.51-8.85). In additional stratified analyses, we found that methylation of the RARB gene significantly increased risk of BCR in African American cases who demonstrated methylation of at least one of the other four genes under study (HR = 3.80; 95%CI 1.07-13.53). These findings may have implications in the early identification of aggressive prostate cancer as well as reducing unnecessary medical procedures and emotional distress for men who present with markers of indolent disease.

    Objectives: The use of gasless laparoscopy with an abdominal wall-lifting device for benign gynecological diseases was compared to conventional laparoscopy with CO_2 pneumoperitoneum. Methods: From February 2007 to July 2007, 76 women with uterine and/or adnexal benign diseases and candidates for laparoscopic surgery were recruited in this study. Thirty-two women underwent gasless laparoscopic surgery and 44 women underwent pneumoperitoneum laparoscopic surgery. Results: Diverse pathologies, including adnexal cyst, uterine myoma and ectopic pregnancy, were treated successfully with gasless laparoscopic surgery. Compared with the patients in the pneumoperitoneum group, the similar hospital stay (P=0.353) and in-traoperative blood loss (P=0.157) were observed. However, the mean operative time in the gasless group was significantly longer than that in the pneumoperitoneum group (P=0.003). No severe intraoperative or postoperative complications were found in either group, except for one case of laparotomic conversion in the pneumoperitoneum group due to dense pelvic adhesions. The total hospital charges were significantly less in the gasless group than in the pneumoperitoneum group (P=0.001). In 38 cases of ovarian cyst resection, the mean operative time in the gasless group remained longer than that in the pneumoperitoneum group (P=0.017). The total hospital charges were also significantly less in the gasless group than in the pneumoperitoneum group (P<0.001). Con-clusion: Our preliminary results demonstrated that the laparoscopic procedure using the gasless technique was a safe, effective method to treat benign gynecological diseases. Moreover, it was easy to master. As a minimally invasive treatment, gasless laparoscopic surgery provides a good choice to patients in the undeveloped regions in China without increasing the patients' and the government's burden significantly.

    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%; pdiseases 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. PMID:27427767

  12. Early kinetics of thyroid trap in normal human patients and in thyroid diseases

    International Nuclear Information System (INIS)

    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)

  13. Iodine Excess as an Environmental Risk Factor for Autoimmune Thyroid Disease

    2014-07-01

    Full Text Available The global effort to prevent iodine deficiency disorders through iodine supplementation, such as universal salt iodization, has achieved impressive progress during the last few decades. However, iodine excess, due to extensive environmental iodine exposure in addition to poor monitoring, is currently a more frequent occurrence than iodine deficiency. Iodine excess is a precipitating environmental factor in the development of autoimmune thyroid disease. Excessive amounts of iodide have been linked to the development of autoimmune thyroiditis in humans and animals, while intrathyroidal depletion of iodine prevents disease in animal strains susceptible to severe thyroiditis. Although the mechanisms by which iodide induces thyroiditis are still unclear, several mechanisms have been proposed: (1 excess iodine induces the production of cytokines and chemokines that can recruit immunocompetent cells to the thyroid; (2 processing excess iodine in thyroid epithelial cells may result in elevated levels of oxidative stress, leading to harmful lipid oxidation and thyroid tissue injuries; and (3 iodine incorporation in the protein chain of thyroglobulin may augment the antigenicity of this molecule. This review will summarize the current knowledge regarding excess iodide as an environmental toxicant and relate it to the development of autoimmune thyroid disease.

    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.

  16. POSSIBLE ROLE OF PROBIOTIC MICROORGANISMS OF BIFIDOBACTERIUM AND LACTOBACILLUS GENUS IN PATHOGENESIS OF AUTOIMMUNE THYROID DISEASES

    Directory of Open Access Journals (Sweden)

    E. P. Kiseleva

    2014-07-01

    Full Text Available It was revealed, that, in blood samples of the patients with autoimmune thyroid diseases, serum antibodies against cell-free fraction of Bifidobacterium bifidum 791 and Lactobacillus plantarum B-01 were detected, respectively, in 71 and 63% of cases, that being two-fold higher than appropriate frequencies in healthy blood donors. An evidence was obtained that presence of some components specifically reacting with autoantibodies against thyroid peroxidase and thyroglobulin on the surface of the microorganisms cells and competing for binding of these immunoglobulins with thyroid antigens. One may also suggest a presence of bacterial components, interacting with thyroid peroxidase. The data obtained let us suggest that probiotic microorganisms of Bifidobacterium and Lactobacillus genus could take part in pathogenesis of autoimmune thyroid diseases, by means of molecular mimicry mechanisms.

    Objective. To determine the prevalence and impact of autoimmune thyroid disease (AITD) in patients with rheumatoid arthritis (RA). Methods. Eight-hundred patients were included. The association between AITD and RA was analyzed was analyzed by bivariate and multivariate analysis. In addition, a literature review was done focusing on geographical variations. Results. In our cohort the prevalence of AITD was 9.8% while the presence of antibodies was 37.8% for antithyroperoxidase enzyme (TPOAb) and 20.8% for antithyroglobulin protein (TgAb). The presence of type 2 diabetes, thrombosis, abnormal body mass index, and a high educational level was positively associated with AITD. The literature review disclosed a geographical variation of AITD in RA ranging from 0.5% to 27%. Autoantibody prevalence ranges from 6% to 31% for TgAb, 5% to 37% for TPOAb, and from 11.4% to 32% for the presence of either of the two. Conclusion. AITD is not uncommon in RA and should be systematically assessed since it is a risk factor for developing diabetes and cardiovascular disease. These results may help to further study the common mechanisms of autoimmune diseases, to improve patients' outcome, and to define public health policies. An international consensus to accurately diagnose AITD is warranted. PMID:23209899

  18. The interventional diagnosis and therapy for thyroid disease should be studied deeply and developed prudently

    International Nuclear Information System (INIS)

    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)

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

    2011-04-01

    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

    2016-01-01

    Autoimmune thyroid disease associated with interferon therapy can manifest as destructive thyroiditis, Graves' Hyperthyroidism, and autoimmune (often subclinical) hypothyroidism, the latter persisting in many patients. There are scare reports of a single patient developing extremes of autoimmune thyroid disease activated by the immunomodulatory effects of interferon. A 60-year-old man received 48 weeks of pegylated interferon and ribavirin therapy for chronic HCV. Six months into treatment, he reported fatigue, weight gain, and slowed cognition. Serum thyroid stimulating hormone (TSH) was 58.8 mIU/L [0.27-4.2], fT4 11.1 pmol/L [12-25], and fT3 4.2 pmol/L [2.5-6.0] with elevated anti-TPO (983 IU/mL [antibodies. He commenced thyroxine with initial clinical and biochemical resolution but developed symptoms of hyperthyroidism with weight loss and tremor 14 months later. Serum TSH was TSH receptor (TRAb, 4.0 U/L [antibodies. Technetium scan confirmed Graves' Disease with bilateral diffuse increased tracer uptake (5.9% [0.5-3.5%]). The patient commenced carbimazole therapy for 6 months. Treatment was ceased following spontaneous clinical and biochemical remission (TSH 3.84 mIU/L, fT4 17pmol/L, fT3 4.5 pmol/L, and TRAb <1 U/L). This raises the need to monitor thyroid function closely in patients both during and following completion of interferon treatment. PMID:27042364

  4. Quantitative thyroid scintigraphy for the differentiation of Graves' disease and hyperthyroid autoimmune thyroiditis

    International Nuclear Information System (INIS)

    The purpose of this study is the evaluation of the TCTUs in the differentiation between AIT and GD in patients with hyperthyroidism. Methods: We determined the TCTUs in 59 patients with untreated hyperthyroid GD and in 51 patients with AIT who had subclinical or manifest hyperthyroidism without medication. Patients with GD were characterized by the presence of hyperthyroidism, decreased echogenicity of the thyroid, elevation of TSH-receptor autoantibodies (TRAb). AIT was defined by a decreased echogenicity of the thyroid, absence of elevated TSH-receptor autoantibodies (TRAb), autoantibodies against the thyroid peroxidase (anti-TPO) and spontaneous remission or development of subclinical hypothyroidism within 3 months. Results: Thyroid volumes of patients with AIT were significantly lower than those of patients with GD (p99mTcO4- offered rapid and reliable differentiation between hyperthyroid GD and AIT. (orig.)

  5. Radiation therapy for benign diseases: patterns of care study in Germany

    International Nuclear Information System (INIS)

    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.

    Globally breast cancer is the leading cause of cancer death among women. The breast consists of epithelium, stroma and a mucosal immune system that make up a complex microenvironment. Growing awareness of the role of microbes in the microenvironment recently has led to a series of findings important for human health. The microbiome has been implicated in cancer development and progression at a variety of body sites including stomach, colon, liver, lung, and skin. In this study, we assessed breast tissue microbial signatures in intraoperatively obtained samples using 16S rDNA hypervariable tag sequencing. Our results indicate a distinct breast tissue microbiome that is different from the microbiota of breast skin tissue, breast skin swabs, and buccal swabs. Furthermore, we identify distinct microbial communities in breast tissues from women with cancer as compared to women with benign breast disease. Malignancy correlated with enrichment in taxa of lower abundance including the genera Fusobacterium, Atopobium, Gluconacetobacter, Hydrogenophaga and Lactobacillus. This work confirms the existence of a distinct breast microbiome and differences between the breast tissue microbiome in benign and malignant disease. These data provide a foundation for future investigation on the role of the breast microbiome in breast carcinogenesis and breast cancer prevention. PMID:27485780

    2009-09-01

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

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

    Full Text Available OBJECTIVE To assess safety and feasibility of non-descent vaginal hysterectomy for benign gynaecological disease. METHODS A prospective study was conducted at the Department of Obstetrics and Gynaecology of P K Das Institute of Medical Sciences from January 2013 to December 2013. An effort was made to perform hysterectomies vaginally in women with benign or premalignant conditions in the absence of prolapse. A suspected adnexal pathology, endometriosis, immobility of uterus, uterus size more than 16 weeks was excluded from the study. Vaginal hysterectomy was done in usual manner. In bigger size uterus, morcellation techniques like bisection, debulking, coring, myomectomy, or combination of these were used to remove the uterus. Data regarding age, parity, uterine size, estimated blood loss, length of operation, intraoperative and postoperative complications and hospital stay were recorded. RESULTS A total of 100 cases were selected for non-descent vaginal hysterectomy. Among them, 97 cases successfully underwent nondescent vaginal hysterectomy. Majority of the patients (55% were in age group 40-45 yrs. Four patients were nulligravida and eight patients had previous LSCS. Uterine size was ≤ 12 weeks in 84 cases and > 12-16 weeks in 16 cases. Commonest indication was leiomyoma of uterus (43%. Mean duration of surgery was 70±20.5 minutes. Mean blood loss was 150±65 mL. Reasons for failure to perform NDVH was difficulty in opening pouch of Douglas in two cases because of adhesions and in one case there was difficulty in reaching the fundal myoma which prevented the uterine descent. Intra–operatively, one case had bladder injury (1% that had previous 2 LSCS. Postoperatively, complications were minimal which included postoperative fever (11%, UTI (8% and vaginal cuff infection was (4%. Mean hospital stay was 3.5 days. CONCLUSION Vaginal hysterectomy is safe, feasible in most of the women requiring hysterectomy for benign conditions with less

In our study, we have endeavoured to assess the prevalence of macroprolactinaemia in euthyroid, regularly menstruating women with thyroid disease, as well as to assess whether autoimmune thyroid disease may result in an increased prevalence of macroprolactinaemia. Material and methods We measured serum Prl in 182 regularly menstruating women aged 32.7 ± 7.5 years (mean ± SD, range 17–46 years who attended endocrine clinic either for investigation of non-toxic goitre (n = 86, age 33.2 ± 7.8 years or with autoimmune thyroid disease (n = 96, age 32.3 ± 7.2 years. Autoimmune thyroid disease was defined as raised titre of at least one anti-thyroid antibody [anti-thyroid peroxidase (anti-TPO, anti-thyroglobulin (anti-Tg and/or anti-TSH-receptor (anti-TSH-R antibodies]. All women were clinically and biochemically euthyroid, either without or on treatment with L-thyroxine. In those with raised Prl (i.e., above 530 mIU/l we ruled out the presence of macroprolactinaemia by polyethylene glycol (PEG precipitation method. Results There was no significant age difference between women with and without autoimmune thyroid disease (p = 0.84. Raised Prl concentrations were found in 10 women with thyroid disease (5.5%, and of those a significant macroprolactinaemia (i.e., reduction of Prl concentrations of more than 60% after PEG precipitation was found in 9 subjects (4.94%. There were no differences in the prevalence of macroprolactinaemia between women with autoimmune thyroid disease (4 out of 96, and without autoimmune thyroid disease (5 out of 86, p = 0.75.

    It is well recognized that the use of external irradiation of the head and neck to treat patients with various non-thyroid disorders increases their risk of developing papillary thyroid carcinoma years after radiation exposure. An increased risk of thyroid cancer has also been reported in survivors of the atomic bombs in Japan, as well as in Marshall Island residents exposed to radiation during the testing of hydrogen bombs. More recently, exposure to radioactive fallout as a result of the Chernobyl nuclear reactor accident has clearly caused an enormous increase in the incidence of childhood thyroid carcinoma in Belarus, Ukraine, and, to a lesser extent, in the Russian Federation, starting in 1990. When clinical and epidemiological features of thyroid carcinomas diagnosed in Belarus after the Chernobyl accident are compared with those of naturally occurring thyroid carcinomas in patients of the same age group in Italy and France, it becomes apparent that the post-Chernobyl thyroid carcinomas were much less influenced by gender, virtually always papillary (solid and follicular variants), more aggressive at presentation and more frequently associated with thyroid autoimmunity. Gene mutations involving the RET proto-oncogene, and less frequently TRK, have been shown to be causative events specific for papillary cancer. RET activation was found in nearly 70% of the patients who developed papillary thyroid carcinomas following the Chernobyl accident. In addition to thyroid cancer, radiation-induced thyroid diseases include benign thyroid nodules, hypothyroidism and autoimmune thyroiditis, with or without thyroid insufficiency, as observed in populations after environmental exposure to radioisotopes of iodine and in the survivors of atomic bomb explosions. On this basis, the authors evaluated thyroid autoimmune phenomena in normal children exposed to radiation after the Chernobyl accident. The results demonstrated an increased prevalence of circulating thyroid

  17. Topical PDT in the Treatment of Benign Skin Diseases: Principles and New Applications

    Directory of Open Access Journals (Sweden)

    2015-09-01

    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.

    Full Text Available La exposición al asbesto es una causa importante de patología pleural y se puede producir con intensidades moderadas o ligeras dada la capacidad del asbesto de concentrarse en la pleura. Ello motiva junto a la prolongada latencia existente entre la exposición y la enfermedad, que sigamos viendo durante muchos años manifestaciones clínicas pleurales de exposición previa, a pesar del uso del asbesto cada vez más limitado en las últimas décadas. Dicha exposición puede presentarse con distintas manifestaciones tanto malignas como el mesotelioma como benignas, siendo las principales de éstas el derrame pleural benigno, las placas pleurales, la fibrosis pleural difusa y la atelectasia redonda.Exposure to asbestos is an important cause of pleural pathology and can be produced with light or moderate tendencies given the capacity of asbestos to concentrate in the pleura. Together with the prolonged latency existing between exposure and the disease, this means that for many years we will continue to see pleural clinical manifestations from past exposure, in spite of the increasingly limited use of asbestos in recent decades. This exposure can show itself in different manifestations, both malign, such as mesothelioma, and benign, principally benign pleural effusion, pleural plaques, diffuse pleural fibrosis and massive atelectasis.

  19. Differential diagnosis of metastatic bone disease and benign bone disease on spine SPECT in patients with low back pain

    International Nuclear Information System (INIS)

    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

    Full Text Available The only hope for effective treatment of liver cancer lies in early detection or screening for populations who are at high risk for developing liver cancer. This study was designed to study the levels of a collection of biochemical markers in the sera of patients suffering from hepatocellular carcinoma (HCC and its predisposing diseases. The ultimate aim is to investigate their diagnostic impact in the early detection of HCC and discriminate from benign liver diseases. The study was carried out on 217 individuals divided into the following groups: Group 1: Normal controls, Group 2: Schistosomal patients (Schist, Group 3: Hepatitis B patients (HBV, Group 4: Hepatitis C patients (HCV, Group 5: Cirrhotic patients (Cirr, and Group 6: Hepatocellular carcinoma patients (HCC. The last group was further subdivided into the following subgroups: a – HCC alone; b – HCC on top of schistosomiasis; c – HCC on top of HBV; d – Hepato-cellular carcinoma on top of HCV; e – HCC on top of cirrhosis. Their sera were subjected to a quantitative determination of the tumour necrosis factor-alpha (TNF-α, epidermal growth factor and its receptor (EGF and EGFR, glutathione-S-transferase alpha (GST-α, iron, ferritin, transferrin, alpha-1-antitrypsin (α1AT and alpha-fetoprotein (αFP. The results of this study indicate that it is advisable to determine a panel of markers composed of αFP, TNF-α and GST-α to confirm diagnosis of HCC and distinguish it from other benign liver diseases.

  1. Objective evaluation of improvement in optic neuropathy following radiation therapy for thyroid eye disease

    International Nuclear Information System (INIS)

    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

    Thyroid nodules are commonly diagnosed in adults. Although rare in children, the risk for thyroid cancer is much higher in the pediatric population compared with adults. Presenting as either a solitary nodule or a multinodular goiter, thyroid nodular disease in children requires a thorough workup that includes a detailed clinical examination comprised of prior history of thyroid disease in the patient or in their family, history of radiation exposure, careful palpation of the thyroid and lymph nodes, blood tests, ultrasonography, and cytological assessment. Thyroid surgery is the gold-standard treatment for pediatric thyroid nodules; nonetheless, the extent of surgery remains controversial. Because surgery is not without risk, the decision matrix necessitates focus on the benefits of surgery for the child contingent upon all the preoperative exams. New diagnostic technology such as molecular testing with fine needle aspiration biopsy may help distinguish between benign and malignant lesions while potentially decreasing surgery for benign disease. The objective of this review is to summarize new concepts in clinical disease management of nodular thyroid disease in the pediatric population, including patient history, medical examination, and diagnosis workup.

    Thyroid hormones, which influence body metabolism and development, could be affected by persistent organic pollutants. We sought to examine the relationship between polybrominated biphenyls (PBBs) and polychlorinated biphenyls (PCBs) and thyroid disease. We employed incidence density sampling to perform a nested case control analysis of the Michigan Long-Term PBB Cohort. Cohort members (n=3333) were exposed to PBBs through contaminated cattle feed in 1973-1974 and to PCBs through daily life. Those with detectable serum PBB and PCB concentrations at enrollment were categorized into tertiles of PBB and PCB exposure. Case-patients were cohort members answering "Yes" to "Has a healthcare provider ever told you that you had a thyroid problem?" during follow-up interviews; control-patients were cohort members answering "No". We used odds ratios (OR) with 95% confidence intervals (CI) to compare odds of thyroid disease by PBB and PCB exposure and by various risk factors. Total cumulative thyroid disease incidence after 33 years was 13.9% among women and 2.6% among men. After adjusting for body mass index, we found no statistically significant differences in odds of any type of thyroid disease among women or men with elevated PBB or PCB exposure. Compared to control-patients, women with thyroid disease had increased odds of being overweight/obese (OR=2.82, 95% CI: 1.94-4.11) and developing infertility (OR=1.71, 95% CI: 1.08-2.69), diabetes (OR=1.61, 95% CI: 1.04-2.51), or arthritis (OR=1.71, 95% CI: 1.18-2.50) during follow-up. Additional research should explore potential associations between PBBs/PCBs and thyroid disease among children exposed in utero. PMID:21737118

    Purpose: the numbers of patients with nonmalignant diseases referred for radiation therapy had to be evaluated for the last 4 years. Patients and methods: in the years 2002, 2004, and 2005 radiation therapy was performed in 61, 40, and 26 patients, respectively. Regularly, more women than men were treated, median age annually was 57, 54, and 55 years, respectively (table 1). The radiotherapy scheme was not modified within the evaluated period. Results: the proportion of nonmalignant diseases among all patients treated decreased from 4.7% in 2002 to 3.3% in 2004 and 2.2% in 2005, respectively. A shift was noticed toward the treatment of four main diseases (endocrine orbitopathy, prevention of heterotopic ossification, meningeoma, tendinitis, table 2). The number of referring physicians decreased from 19 to six. Conclusion: due to administrative restrictions for treatment in hospitals, budget restrictions in private practices and lasting, insufficient revenues for radiotherapy in nonmalignant diseases, radiation therapy for the entire group of benign diseases is endangered.

    Hashimoto's thyroiditis has been shown to be associated with the HLA-specificities DR4 and DR5. Since former association studies yielded variable results, we used novel molecular typing methods to assess predisposing immunogenetic factors. Gene analysis of the HLA-DR-DQ and tumor necrosis factor region was performed in a group of Hashimoto's thyroiditis patients and randomly chosen controls using standards and nomenclature of the 10th International Histocompatibility Workshop. Genomic DNA of patients and controls was analyzed using a cDNA probe of the DQB1 gene. The resulting restriction fragment patterns allowed the determination of newly defined DQw-types 1-9. We find the strongest relative risk conferred by DQw7 (RR = 4.7), that is observed in 36 of 64 patients (56%) and only 21 of 98 controls (21%) (P corr less than 0.002). Comparison of DNA sequence variation in the DQB1 gene, that is found predominantly in Hashimoto's thyroiditis patients, indicates that codons 45 and 57 are critical features in DQw7 which distinguish it from other DQw specificities. The adjacent DQA1 genes also display a significant association with Hashimoto's thyroiditis (DQA1*0201/*0301 heterozygotes were found in 37% of patients and 15% controls, P less than 0.03). No significant association could be found with polymorphisms of the tumor necrosis factor gene. These results provide a new basis for the concept of genetic susceptibility in Hashimoto's thyroiditis and will help to elucidate the underlying autoimmune mechanisms that lead to disease at the functional level.

    Full Text Available Background Maternal thyroid disease in pregnancy is associated with adverse impact on both mother and fetus. Both the American thyroid association and the endocrine society have recently published guidelines for the management of thyroid disease in pregnancy. Objectives The objective of this survey was to assess and compare the current practices of various East-Asian physicians in the screening and management of thyroid disease in pregnancy. Materials and Methods Completed survey questionnaires were collected from 112 physicians of six East-Asian countries. The survey was based on clinical case scenarios, asking questions about the clinical practices related to diagnosis and management of thyroid disease during pregnancy. Reponses from 76 endocrinologists and 33 internists and general practitioners (generalists were analyzed. Results There were minor differences in treatment preferences for Graves’ disease in pregnancy and tests to monitor antithyroid drugs between endocrinologists and generalists; the major difference being targeted free thyroxin, and also thyroxin, depicted in the upper end of normal range, by the majority of endocrinologist and within the normal range, by generalists. Compared to generalists, endocrinologists perform more targeted screening and are more familiar with its risk factors. Predominantly, endocrinologists increase levothyroxine dose in hypothyroid women, upon confirmation of pregnancy and also indicate full dose in a pregnant woman, diagnosed with overt hypothyroidism, and treat thyroid peroxidase antibody positive or negative pregnant women with thyroid stimulating hormone (2.5 - 5 mU/L, as compared to generalists. Conclusions There is wide variation in the clinical practices of screening and management of thyroid disorders during pregnancy in East-Asia, with many clinicians, in particular general practitioners, not adhering to clinical practice guidelines, unfortunately.

    2016-01-01

    Preoperative diagnosis and operative planning for patients with thyroid nodules has improved over the last decade. The Bethesda criteria for cytopathologic classification of thyroid nodule aspirate has enhanced communication between pathologists and clinicians. Multiple genetic tests, including molecular markers and the Afirma gene expression classifier, have been developed and validated. The tests, along with clinical and radiologic information, are most useful in the setting of indeterminate cytology. The development of an updated diagnostic and treatment algorithm incorporating all available tests will help standardize the management of patients with nodular thyroid disease and reduce variation and inefficiencies in care.

    Increase of intracellular positive ions (mainly Na(+)) indicates greater possibility of cell malignancy. The present study investigated the correlation between the Na(+) micro-current value (MCV) and tissue characteristics (normal, benign or malignant). 346 tissue samples have been detected within 30 min after surgical isolation by Na(+) detector. MCV in 102 malignant tumor was significantly higher than that in benign/borderline tumor or normal tissue (33.3 ± 8.9 μA vs. 24.4 ± 8.6 μA and 14.0 ± 4.0 μA, p detector and pathological examination was different in tissues from different organs or systems, which was high in pancreas, bile duct system, gastrointestinal system, esophagus, breasts, lungs, nose &throat and thyroids, but poor in urinary tissue. The overall coincidence rate was 83.1% (108/130) between Na(+) detector and pathological examination. The sensitivity and specificity of correct diagnosis by Na(+) detector was 83.3% (70/84) and 82.6% (38/46), respectively. This new modality may have diagnostic potential in complementing frozen examination in differentiating malignant tumor from benign or normal tissue, justifying tumor metastatic scope and confirming surgical margin.

    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

  11. Biomonitoring of organochlorines in women with benign and malignant breast disease

    International Nuclear Information System (INIS)

    Established risk factors for breast cancer explain breast cancer risk only partially. Organochlorines are considered to be a possible cause for hormone-dependent cancers. A hospital-based case-control study, the first from India, was conducted among 50 women undergoing surgery for breast disease to examine the association between organochlorine exposure and breast cancer risk. Blood, tumor, and surrounding adipose tissue of the breast were collected from the subjects with benign (control) and malignant breast (study) lesions and analyzed to determine organochlorine insecticides using a gas-liquid chromatograph equipped with an electron capture detector. The α, β, γ, and δ isomers of hexachlorocyclohexane (HCH), p,p'-dichlorodiphenyltrichloroethane (DDT), o,p'-DDT, p,p-dichlorodiphenyldichloroethylene, and p,p'-dichlorodiphenyldichloroethane were frequently detected in three specimens. Total HCH and total DDT levels were higher in the blood of the study group (25 cases) than in those of the controls (25 cases) with only γ-HCH being significantly different (P0.05). However, both total HCH and total DDT were higher in the tumor tissues of the controls than in those of the study group; γ-HCH was significantly different (P0.05). The level of total HCH (α-HCH was significantly different, P0.05) was higher in the breast adipose tissue of the study group, whereas total DDT was higher in the breast adipose tissue of the control group. The distribution of known confounders of breast cancer including age, body mass index, age at menarche and menopause, duration of breast feeding, and family history related to breast disease did not differ significantly between benign and malignant groups. This pilot study with limited statistical power does not support a positive association between exposure to organochlorines and risk of breast cancer but paves the way for a larger Indian study with greater statistical power encompassing different regions of the country to enable

    Full Text Available Objective: The study was undertaken to quantify thyroid hormones in undialyzed chronic kidney disease patients’ verses controls and to study the correlation between renal function markers and thyroid hormones. Background: Chronic kidney disease (CKD is associated with a higher prevalence of primary hypothyroidism (HT, but at the same studies on thyroid hormone status in uremic patients has reported conflicting results. Methods: Thyroid hormones and renal function parameters like serum urea, creatinine, creatinine clearance, total protein and albumin were estimated and correlations between thyroid hormones and renal function parameters were studied in 60 undialyzed chronic kidney disease patients’ verses 100 healthy controls. Results: We found both T3 and T4 were significantly reduced (p<0.0001 for T3 and 0.007 for T4 whereas TSH remains to be unchanged in patient group compared to controls. We also observed that urea and creatinine were negatively correlated whereas creatinine clearance was positively correlated with both T3 and T4 that has high statistical (two-tailed significance at 0.01 level. But urea alone is negatively correlated with TSH that has statistical (two-tailed significance at 0.05 level. Conclusion: From our data, we speculate that renal insufficiency may lead to thyroid hormone disturbances.

    Laparoscopic surgery has become well established in the management of both and malignant colorectal disease. The last decade has seen increasing numbers of surgeons trained to a high standard in minimally-invasive surgery. However there has not been the same enthusiasm for the use of laparoscopy in emergency colorectal surgery. There is a perception that emergent surgery is technically more difficult and may lead to worse outcomes. The present review aims to provide a comprehensive and critical appraisal of the available literature on the use of laparoscopic colorectal surgery (LCS) in the emergency setting. The literature is broadly divided by the underlying pathology; that is, inflammatory bowel disease, diverticulitis and malignant obstruction. There were no randomized trials and the majority of the studies were case-matched series or comparative studies. The overall trend was that LCS is associated with shorter hospital stay, par or fewer complications but an increased operating time.Emergency LCS can be safely undertaken for both benign and malignant disease providing there is appropriate patient selection, the surgeon is adequately experienced and there are sufficient resources to allow for a potentially more complex operation.

  1. Radiation-related thyroid dysfunction: implications for the treatment of Hodgkin's disease

    International Nuclear Information System (INIS)

    Thyroid-stimulating hormone (TSH) and thyroxine (T4) 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 T4 levels. Among 45 who did not receive mantle irradiation, only three had evidence of dysfunction and none of these had T4 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

  2. An update on diagnostic methods in the investigation of diseases of the thyroid

    International Nuclear Information System (INIS)

    Iodine deficiency and iodine-deficiency disorders continue to be problems in several parts of Europe, requiring further improvements in the techniques employed in thyroid diagnosis, and particularly in the early diagnosis and risk assessment of autonomously functioning thyroid tissue. For the latter purpose, scintigraphy with technetium-99m pertechnetate under exogenous or endogenous thyroid-stimulating hormone (TSH) suppression provides the best results. Significant methodological improvements in laboratory tests have resulted from the application of new luminescent techniques and gene technology to thyroid function tests. Especially TSH measurement using second- or third-generation assays ensures diagnostic accuracy, so that the thyrotropin-releasing hormone (TRH) test is now almost always unnecessary. The differentiation of blocking and stimulating TSH receptor antibodies is relevant when discrepant results are obtained with respect to thyroid function. Determination of glycosaminoglycans in urine may become a helpful tool in the follow-up of endorine ophthalmopathy. Some new imaging agents have recently been applied in the scintigraphy of thyroid diseases, such as octeotide, or in tyhroid diagnosis, such as fluorodeoxyglucose. Both improve the detectability of metastases of thyroid cancer, especially if the radioiodine scan is negative. (orig.)

    Full Text Available A despeito do caráter benigno da endometriose, estima-se que 1% dos casos esteja relacionado com câncer, especialmente quando ambas as condições ocorrem nos ovários. Lesões extra-ovarianas encontradas no septo retovaginal, cólon, bexiga, vagina e peritônio da região pélvica também já foram associadas com neoplasias malignas. Várias características do tecido endometrial ectópico o aproximam do fenótipo neoplásico, e a própria endometriose possui comportamento tipicamente neoplásico com capacidade de invasão do estroma adjacente e associação com lesões à distância. Esta revisão atualiza conhecimentos diagnósticos, clínicos e terapêuticos dos implantes intestinais de tecido endometriótico, bem como sua relação com processos neoplásicos para melhor compreensão de seu caráter benigno ou de seu eventual potencial para malignidade.Endometriosis is generally assumed to be a benign disease, but it is estimated that 1% of cases are associated with cancer, especially when both conditions are present in the ovary. Extra-ovarian lesions in the rectovaginal septum, colon, bladder, vagina and peritoneum were already associated with malign neoplasia. Several characteristics of endometrial tissue are very similar to the neoplasia phenotype. Endometriosis itself typically behaves as a neoplasia process, spreading over adjacent stroma and being associated with distant lesions. This is an update on the diagnostic, clinical, and therapeutic knowledge of, management of bowel implants of endometrial tissue, as well as the relation with neoplastic processes to better understand its benign nature or eventual potential for malignancy.

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

  5. Differentiation between malignant and benign thyroid tumors by X-ray fluorescent analysis-comparison of cases from Russia and Albany, New York

    International Nuclear Information System (INIS)

    Intra thyroid iodine level in different types of thyroid neoplasms in Russia (126 cases) and USA (37 cases) were investigated by X-ray fluorescent analysis in vitro. A decrease in intra thyroid iodine concentration is associated with the stepwise loss of differentiation in thyroid tumors. In colloid goiter tissue from Russia, the intra thyroid iodine level is increased. The intra thyroid iodine level was markedly increased in micro follicular adenomas and colloid goiters from American patients which may reflect a higher iodine supply in the USA. X-ray fluorescent analysis together with careful clinical appraisal can be used for management of thyroid patients with suspicious nodules which should be treated by surgery

  6. Evaluation of radiation exposure from patients with thyroid disease by iodine-131 therapy

    International Nuclear Information System (INIS)

    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

    Graves' disease (GD) is a common autoimmune disease (AID) that shares many of its susceptibility loci with other AIDs. The thyroid stimulating hormone receptor (TSHR) represents the primary autoantigen in GD, in which autoantibodies bind to the receptor and mimic its ligand, thyroid stimulating...... hormone, causing the characteristic clinical phenotype. Although early studies investigating the TSHR and GD proved inconclusive, more recently we provided convincing evidence for association of the TSHR region with disease. In the current study, we investigated a combined panel of 98 SNPs, including 70...

  10. Thyroid function 10-18 years after mantle field irradiation for Hodgkin's disease

    International Nuclear Information System (INIS)

    Thyroid function was measured in 81 patients who had been curatively irradiated on a mantle field for Hodgkin's disease 10-18 years ago. 47 patients (58%) had elevated levels of thyroid stimulating hormone, indicating hypofunction of the thyroid gland, compared with 4.6% of controls (hospital visitors) matched for age and sex. The mean free thyroxine index (FTI) was significantly lower in patients than in controls, but all FTI values were still normal. Age at the time of irradiation, sex, time since irradiation and administration of chemotherapy were not significant factors in the development of thyroid dysfunction. A life-long awareness of the possibility of insidiously developing myxedema in these patients is strongly advocated. (Author)

  11. A case of Graves' disease with false hyperthyrotropinemia who developed silent thyroiditis.

    1991-12-01

    We encountered a patient who developed silent thyroiditis during the course of Graves' disease. The diagnosis of silent thyroiditis was made on the basis of a low thyroidal 131I uptake, no response to the thyrotropin releasing hormone (TRH) test, and subsequent hypothyroidism despite the presence of high titers of thyrotropin (TSH) receptor antibody (TRAb) and thyroid stimulating antibody (TSAb). The patient, in addition, had a discrepancy between serum TSH and thyroid hormone values. This was due to the presence of interfering substances that react to mouse IgG in the sera since serum TSH levels were decreased in a dose dependent manner by the addition of increasing amounts of mouse IgG to the sera. It should therefore be noted that silent thyroiditis can develop in patients with Graves' disease. Furthermore, clinicians should be aware that two-site immunoassay kits that use mouse monoclonal antibodies are subject to interference by some substances, possibly antibodies which react to mouse IgG.

  12. A case of Graves-Basedow disease with orbitopathy and papillary thyroid cancer

    International Nuclear Information System (INIS)

    Coexistence of Graves-Basedow disease with orbitopathy and thyroid cancer is believed to be a rare event. A 39-year-old man with clinical features of hyperthyroidism associated with exophthalmos and goitre presented to out patient clinic. Thyroid function tests showed hyperthyroidism with elevated thyroid-stimulating antibodies. Graves-Basedow disease was diagnosed. Ultrasound revealed diffuse thyroid enlargement with hypoechoic pattern and hypoechoic lesions with regular edges of 1.0 cm diameter at the left and right lobe. Fine needle aspiration biopsy was negative. Due to the patients nodular goitre and mild orbitopathy, after some further 3 months of anti-thyroid medication, near total thyroidectomy was performed. Histologically, papillary micro carcinoma was found. Following surgery, the patient was referred to our Department of Endocrinology, L-thyroxine suppression treatment was commenced. Approximately 8 weeks post surgery, the patient reported with eye discomfort, soft tissue oedema and double vision. On CT thickening of the left superior rectus muscle was found. Methylprednisolone pulse therapy was applied (4 weeks, 2 grams per week). Glucocorticoid therapy resulted in significant improvement of soft tissue inflammation and of diplopia. The patient was qualified for 131I radioiodine complementary therapy (3657 MBq) and orbital irradiation. While some authors suggest that radioiodine therapy may be associated with worsening of pre-existing orbitopathy, so far we have not observed it in our patient, perhaps due to thyroid removal as a source of autoreactive T lymphocytes and the protective effect of applied glucocorticoids.

  13. Identification of chosen apoptotic (TIAR and TIA-1) markers expression in thyroid tissues from adolescents with immune and non-immune thyroid diseases

    International Nuclear Information System (INIS)

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

    From 1983 to 1994 Phase II and III clinical studies at Henry Ford Hospital demonstrated complete or partial responses in 46 of 47 patients treated with hematoporphyrin-derivative photodynamic therapy (HPD-PDT) for a variety of benign and malignant upper aerodigestive tract disease: (1) superficial `condemned mucosa' or `field cancerization' of the oral cavity; (2) stage III/IV head and neck cancer; (3) mucocutaneous AIDS-related Kaposi's sarcoma of the upper aerodigestive tract; (4) recurrent laryngotracheal papillomatosis; (5) severe dysplasia/adenocarcinoma in situ in Barrett's esophagus; (6) partial or completely obstructing terminal esophageal cancer. HPD-PDT produced complete responses in 19 patients (follow up 6 months to 8 years) with `field cancerization' (CIS, T1) of the oral cavity and larynx (6), adenocarcinoma in situ in Barrett's esophagus (2), mucocutaneous Kaposi's sarcoma (9), obstructing esophageal carcinoma (1), and stage IV squamous cell carcinoma of the nasopharynx (1). PDT treatment protocols, results, complications, and application as adjunct or primary oncologic therapy for head and neck disease are reviewed.

    Full Text Available BACKGROUND AND AIM: The presence of thyroid nodules with Graves′ disease raises concern about co-existent thyroid malignancy. The objective of this study is to evaluate the risk of thyroid carcinoma and the need for surgical intervention in, patients with Graves′ disease with co-existent nodules in an endemically iodine deficient area (IDA. SUBJECTS AND METHODS: Retrospective study of 130 surgically managed patients of Graves′ disease (1990-1999. Out of these 35 (26.9% cases had palpable nodules. No patient had history of previous head and neck irradiation or radioiodine therapy. The clinico-pathological findings and follow-up of these cases were noted. RESULTS: Mean age of patients with nodules was 40.2 +/- 9.5 years and male to female ratio was 1:2.2. The overall incidence of thyroid carcinoma in Graves′ disease was 6.2% (8/130 cases, while the incidence, in cases having nodule with Graves′ disease was 17.1% (6/35 cases. The median age of patients with carcinoma was 45 years (5 women and 1 man. Besides laboratory investigations for hyperthyroidism, preoperative investigations included fine needle aspiration cytology (FNAC and thyroid scintigraphy in 29 and 25 cases respectively. Incidence of malignancy in palpable cold nodules was 20%. FNAC could not predict malignancy with certainty in any of these cases. Five patients had papillary thyroid carcinoma while one had follicular carcinoma. Median tumour diameter was 10 mm. Tumour was multi-centric in two cases while one case had metastases to cervical lymph node. In follow-up (median =5.5 years one patient died of unrelated cause, while rest are alive with no evidence of disease. CONCLUSIONS: Nodules are frequently associated with Graves′ disease in IDA. Incidence of carcinoma is high in palpable cold nodule. We recommend early thyroidectomy in these cases.

    1,25-Dihydroxyvitamin D is a steroid hormone derived from vitamin D, playing an important role in maintaining an adequate serum level of calcium and phosphorus. It is now clear that vitamin D exerts an endocrine action on the cells of the immune system, generating anti-inflammatory and immunoregulatory effects. The mechanisms underlying the role of vitamin D in autoimmunity are not completely understood. Lower vitamin D levels have been found in several autoimmune diseases, such as rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, type 1 diabetes mellitus, multiple sclerosis, inflammatory bowel diseases, autoimmune thyroid diseases (i.e. Hashimoto's thyroiditis and Graves' disease) and autoimmune gastritis. Several genetic studies have demonstrated an association between thyroid autoimmunity susceptibility and gene polymorphisms of vitamin D receptor, vitamin D binding protein, 1-alpha-hydroxylase and 25-hydroxylase. Of note, some papers do not confirm this connection. With regard to the role of vitamin D in autoimmune thyroid diseases, available data remain controversial. Only few reports have analyzed the supposed association between autoimmune thyroid diseases and vitamin D concentration with inconclusive results. In our experience, low serum levels of vitamin D do not correlate either with Hashimoto's thyroiditis or with Graves' disease. The inability to achieve an unambiguous conclusion is in part due to the limitations in study design. In fact, most of the studies are cross-sectional surveys with a small number of subjects. In addition, the heterogeneity of the study population, seasonal variation of blood sampling, inter-method analytical variability of vitamin D assays and different definitions of vitamin D deficiency/insufficiency contribute to contradicting results. Therefore, further randomized, controlled, prospective trials are needed in order to demonstrate the causality of vitD in AITD and consequently the role of vitamin D

    Full Text Available The aim of the study was an estimation of the level of nutrition knowledge on iodine deficiency in woman with diagnosed thyroid diseases and its comparison with healthy woman’s knowledge. The study was conducted by direct interview method among 400 women – 200 patients of the Clinic of Thyroid Diseases in Poznan (Poland and 200 “healthy” individuals (thyroid diseases were not diagnosed. Respondents were asked to give their opinion to the sequence of statements relating to iodine deficiency prophylaxis. A sufficient level of knowledge was found in terms of basic issues concerning iodine deficiency, i.e. the role of iodine in the thyroid gland functioning and its sources in the diet. However, both in the group of patients and healthy individuals, a low level of knowledge was found connected with the effect of thermal processing on iodine content in food and food limiting the iodine supply. The level of nutrition knowledge in woman with diagnosed thyroid disease was higher than in healthy woman. Due to the role of knowledge on factors limiting the iodine supply from the diet for the effectiveness of iodine deficiency prophylaxis, it is essential to include them in nutrition education.

  20. [Pathogenesis of thyroid eye disease - does autoimmunity against the TSH receptor explain all cases?].

    Science.gov (United States)

    Wall, Jack R; Lahooti, Hooshang

    2011-01-01

    Thyroid associated ophthalmopathy, or thyroid eye disease (TED), is a complex inflammatory disorder of the eye that, as its name implies, is usually associated with thyroid disease. Clinical observation supports the existence of three main TED subtypes, namely ocular myopathy, congestive myopathy, and mixed congestive and myopathic ophthalmopathy. Although the precise pathophysiology of TED remains unclear, it is likely to reflect an autoimmune reaction involving sensitised T lymphocytes and autoantibodies directed against a specific orbital or thyroid-and-orbital shared antigen(s). One well-studied candidate in this immune reaction is the thyroid-stimulating hormone receptor (TSHR), which is also expressed in the orbital fibroblast and preadipocyte. Most patients with ophthalmopathy have associated Graves' disease, 10% have Hashimoto's thyroiditis in which the eye changes are often mild and expressed mainly as upper eyelid retraction (UER), and 10% have no apparent associated thyroid disease - so-called "euthyroid Graves' disease". Ophthalmopathy can also occur in some patients with transient thyroiditis, thyroid cancer, and Graves' disease many years after treatment of the hyperthyroidism - situations where TSHR antibodies are not expected to be present, suggesting that the relationship between TSHR antibodies and the eye disorder has not been established for all cases. In our studies of TED we have investigated the nature and significance of antibodies targeting other eye muscle and orbital connective tissue (OCT) antigens, in particular the calcium binding protein calsequestrin (CASQ1) and the orbital fibroblast membrane antigen collagen XIII. Our working hypotheses for the pathogenesis of TED are: i) the initial reaction in the orbit is antibody and T lymphocyte targeting of the TSHR in the OCT compartment, and ii) the associated extra ocular and upper eyelid muscle inflammation reflects either autoimmunity against primary skeletal muscle antigens such as CASQ

    Purpose: To assess the shape of the dose-response for various circulatory disease endpoints, and modifiers by age and time since exposure. Methods and Materials: This was an analysis of the US peptic ulcer data testing for heterogeneity of radiogenic risk by circulatory disease endpoint (ischemic heart, cerebrovascular, other circulatory disease). Results: There were significant excess risks for all circulatory disease, with an excess relative risk Gy{sup -1} of 0.082 (95% CI 0.031-0.140), and ischemic heart disease, with an excess relative risk Gy{sup -1} of 0.102 (95% CI 0.039-0.174) (both p = 0.01), and indications of excess risk for stroke. There were no statistically significant (p > 0.2) differences between risks by endpoint, and few indications of curvature in the dose-response. There were significant (p < 0.001) modifications of relative risk by time since exposure, the magnitude of which did not vary between endpoints (p > 0.2). Risk modifications were similar if analysis was restricted to patients receiving radiation, although the relative risks were slightly larger and the risk of stroke failed to be significant. The slopes of the dose-response were generally consistent with those observed in the Japanese atomic bomb survivors and in occupationally and medically exposed groups. Conclusions: There were excess risks for a variety of circulatory diseases in this dataset, with significant modification of risk by time since exposure. The consistency of the dose-response slopes with those observed in radiotherapeutically treated groups at much higher dose, as well as in lower dose-exposed cohorts such as the Japanese atomic bomb survivors and nuclear workers, implies that there may be little sparing effect of fractionation of dose or low-dose-rate exposure.

  2. 3,3'-Diindolylmethane, a cruciferous vegetable derived synthetic anti-proliferative compound in thyroid disease

    International Nuclear Information System (INIS)

    Considerable epidemiological evidence exists to link thyroid disease with differing patterns of dietary consumption, in particular, cruciferous vegetables. We have been studying the anti-thyroid cancer (TCa) activity of indole-3-carbinol (I3C) found in cruciferous vegetables and its acid catalyzed dimer, 3,3'-diindolylmethane (DIM). There are no studies as yet to elucidate the effect of these compounds on the altered proliferative patterns in goiter or thyroid neoplasia. In this study, we tested the anti-proliferative effects of I3C and DIM on four different thyroid cancer cell lines representative of papillary (B-CPAP and 8505-C) and follicular carcinoma of the thyroid (CGTH-W-1 and ML-1), and primary human goiter cells. Cell survival and IC50 values for I3C and DIM were calculated by the XTT assay and cell cycle distribution analysis was done by flow cytometry. DIM was found to be a better anti-proliferative agent than I3C in both papillary and follicular TCa resulting in a greater cytotoxic effect at a concentration over three fold lower than predicted by the molar ratio of DIM and I3C. The anti-proliferative activity of DIM in follicular TCa was mediated by a G1 arrest followed by induction of apoptosis. DIM also inhibited the growth of primary goiter cells by 70% compared to untreated controls. Contrary to traditional belief that cruciferous vegetables are 'goitrogenic,' DIM has anti-proliferative effects in glandular thyroid proliferative disease. Our preclinical studies provide a strong rationale for the clinical exploration of DIM as an adjuvant to surgery in thyroid proliferative disease

  3. The clinical value of detection of serum TGAb and TPOAb level in autoimmune thyroid diseases

    International Nuclear Information System (INIS)

    To study the clinical value of serum TGAb and TPOAb levels in the diagnosis of patients with autoimmune thyroid diseases (AITD), the serum levels of TGAb and TPOAb in 175 patients with AITD and 64 non-AITD patients and 57 health controls were measured by RIA. The results showed that the serum levels of TGAb and TPOAb in AITD patients with GD and HT were significantly higher than that of control group (P0.05). The detection of serum TGAb and TPOAb levels may have clinical value in the diagnosis, treatment and prognosis of autoimmune thyroid diseases. (authors)

  4. Radioimmunoassay measurements of serum thyrotropin in patients with hypothalamic-pituitary and thyroid diseases

    International Nuclear Information System (INIS)

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

    For a better understanding of the pathogenesis of thyroid autoimmune diseases, we have studied morphological and functional properties of T clones from peripheral blood lymphocytes (PBL) and from intrathyroidal lymphocytes (ITL) obtained from 3 patients with Graves' disease or 1 Hashimoto's thyroiditis. Investigations were carried out on clones cultured alone or cocultured with autologous thyrocytes. Clonage efficiency ranged from 30% to 33% for PBL and 10% to 36% for ITL. A predominance of CD4-positive clones was observed whatever the origin of the lymphocytes or the autoimmune pathology. Gamma interferon (IFN-gamma) was detected in the majority (17/19) of the clones tested. Intracytoplasmic interleukin (IL-4) was secreted in 7/19 clones and both cytokines were produced in 5/19 clones. In coculture a proliferative response and tumour necrosis factor (TNF-alpha) production were observed with 6 clones (4 from Graves thyrocytes and 2 from thyroiditis). No cytotoxic clone was derived from Graves or thyroiditis tissues. These data demonstrate that the large majority of T clones are principally CD4-T cells; all the clones secreted TNF-alpha and a large majority produced IFN-gamma. Only a few clones produced IL-4 alone or associated with IFN-gamma. Six T clones induced proliferative response and of TNF-alpha secretion in coculture. Further investigations must be performed on these antigen-reactive T clones to analyse their role in the pathogenesis of the human thyroid autoimmune diseases. PMID:10739333

  6. Radiation induced thyroid neoplasms 1920 to 1987: A vanishing problem

    International Nuclear Information System (INIS)

    Radiation for benign diseases has been implicated as an etiologic factor in thyroid cancer. From 1930-60, over 2 million children may have been exposed to therapeutic radiation and it is estimated that up to 7% may develop thyroid cancer after a 5-40 year latency. Thyroid stimulating hormone, secondary to radioinduced hypothyroidism, has been implicated as causative in animals. Such data has led to expensive screening programs in high risk patients. Because of a decline in irradiation for benign diseases in children over the last 2 decades, we questioned whether the incidence of radiation induced thyroid neoplasms (RITN) was also decreasing. Twenty-six of 227 patients (11%) with thyroid malignancies seen at our institution from 1974-87 had a history of previous head and neck irradiation. These included 13 papillary, 3 follicular, and 7 mixed carcinomas as well as 2 lymphomas and 1 synovial cell sarcoma. None of these 26 patients had abnormal thyroid function tests at presentation. Mean latency from irradiation to the diagnosis of thyroid cancer was 25.4 years (6-55 year range). Compared to the reported increasing incidence of RITN from 1940-70, there appears to be a significant decrease since 1970. Based on our analysis, the use of expensive screening programs in high risk populations may no longer be warranted. Additionally, the routine use of thyroid replacement in previously irradiated chemically hypothyroid patients is not recommended.30 references

    Several studies have investigated the relation between benign breast diseases (BBD) and food intake. However, dietary patterns of these patients have not been taken into consideration up to now. The aim of this study is to determine the association between dietary patterns and BBD. In this case-control study, ninety-six patients with BBD and seventy controls were selected from women attending the Iranian Center for Breast Cancer affiliated with Academic Center for Education, Culture and Research. Demographic, physical activity and semi-quantitative FFQ were completed. The main dietary patterns were extracted by factor analysis. Two major dietary patterns emerged: Healthy dietary pattern including fish, poultry, eggs, low-fat dairy products, vegetables, legumes, nuts and seeds, whole grains, oil and mayonnaise, olives, fruits; and Unhealthy dietary pattern including red meats, organ and processed meats, high-fat dairy products, refined grains, sweets and desserts, animal and solid fats. After adjustment for age, BMI and energy intake, the participants in the highest tertile of Healthy dietary pattern (OR 0·44; 95 % CI 0·20, 0·99) were less likely to have BBD compared with those in the first tertile. After adjustment for other confounding variables, this relationship still remained close to significant level. However, higher consumption of Unhealthy dietary pattern was not associated with the risk of BBD. In conclusion, Healthy dietary pattern might be inversely associated with the risk of BBD; however, this result should be interpreted with caution. Future studies are needed to confirm our findings.

  9. Estimation of the carcinogenic risk of radiotherapy of benign diseases from shoulder to heel

    International Nuclear Information System (INIS)

    Background and purpose: To estimate risk on fatal tumour induction in patients by radiotherapy of benign diseases at various body sites, including heterotopic ossification, omarthritis, gonarthrosis, heel spurs and hidradenitis suppurativa. Material and methods: The carcinogenic risk is estimated by applying the effective dose concept from the ICRP with the average risk factor of 10% per Sv for high dose and high dose rate. Although, the concept of effective dose for the present study has limitations, its use is considered acceptable for a fairly rough risk estimate. The organ doses are calculated using a Monte Carlo radiation transport code and anthropomorphic mathematical phantoms. Special risk modifying factors like patient's age at exposure and gender are taken into account. Results: For the treatment of heterotopic ossification, omarthritis, gonarthrosis, heel spurs and hidradenitis suppurativa the effective dose is in the range of 5-400 mSv. For an average-aged population, the estimated number of radiation-induced fatal tumours due to these treatments is assessed to be between 0.5 and 40 persons per 1000 patients treated. At higher ages the risks are reduced. Conclusions: The range of effective doses found for the various types of treatment at various body sites is large. There are several possibilities to optimise the treatment protocols resulting in reduced effective doses and related radiation risks

  10. The investigation of cytokine level in peripheral blood of patients with thyroid eye disease

    International Nuclear Information System (INIS)

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

    The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients. PMID:24509292

    International Nuclear Information System (INIS)

    To assess the utility of 2-[18F] fluoro-2-deoxy-D-glucose (FDG) PET in differentiating malignant and benign diffuse pleural disease, lkand to compare it with CT. Both FDG PET and CT scans were performed in 20 conseutive patients with diffuse pleural disease(13 malignant and seven benign cases). in FDG PET, peak standardized uptake value (SUV) as well as visual assessment of abnormally increased uptake in the pleura was evaluated. The results were compared with CT findings. With only visual assessment of PET images, sensitivity, specificity, and accuracy for malignancy were 92%, 43%, and 75%, respectively. With peak SUV of 4.8 or more, the corresponding figures were 100%, 57%, and 85%, respectively, and on CT interpretation, were 100%, 57%, and 85%, respectively. Tuberculous empyema simulated malignant pleural disease both on FDG PET (3/6 patients with peak SUV more than 4.8) and CT (3/6 patients). For the differentiation of malignant and benign diffuse pleural disease, FDG PET and CT are equally accurate. Combined visual and quantitative assessments of PET images enhance discriminatory ability. Tuberculous empyema simulates malignant pleural disease both on FDG PET and CT

  14. Study of the expression for apoptosis factors of thyroid cells after arterial embolization to treat hyperthyroidism caused by Graved' disease

    International Nuclear Information System (INIS)

    Objective: To study the expressions of Fas, FasL, Bax,Bcl-2 and P53 in thyroid tissue and to analyzis (Semi-quantitative analysis)the relation between change of apoptosis in thyroid tissues and clinical therapeutic effect after thyroid arterial embolization in treating hyperthyroidism caused by Graves' disease with observation of apoptosis for 3 years. Methods: 15 patients undergone core needle biopsy of the thyroid gland were divided into three groups according to the amount of time elapsed after thyroid arterial embolization: A group, before thyroid arterial embolization, B group, 1 year group (including 7-day subgroup, 3-month subgroup, 6-month subgroup) and C group, 1 year subgroup and mom than 1 year subgroup after arterial embolization. Results: (1) After embolisation, 15 patients' symptoms and signs of hyperthyroidism disappeared or improved greatly with 9 long term released and 6 improved with small amount of ATD maintenance. (2) The positive staining of Fas and FasL located in endochylema and cell-membrane of thyroid tissue from patients treated with transcathter arterial embolization were higher than those not treated with transcathter arterial embolization (P0.05). (4) The positive cell and the staining of P53 in thyroid tissue had significant difference before and after thyroid arterial embolization (P<0.05). Conclusions: The extra-expression and the increased expression of Fas, FasL, Bax, P53 in thyroid tissue of patient with GD treated by thyroid arterial embolization are correlated with the effects of interventional therapy.

  15. Enhanced thyroid iodine metabolism in patients with triiodothyronine-predominant Graves' disease

    International Nuclear Information System (INIS)

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

  16. A simplified scheme for the investigation of thyroid function in chronic liver disease.

    The investigation of thyroid disease in the presence of chronic liver disease (CLD) is difficult. Conventional tests are influenced by chronic illness and abnormal concentrations of binding proteins. A three tier system is normally used; thyroxine (T4), then T3 or TSH and an index for binding proteins. The recently introduced TSH immunoradiometric assays (IRMA) offer the potential of a single test assessment of thyroid function. This was assessed by the measurement of T4, T3, THBC and the free thyroxine indices in subjects with CLD. Conventional tests showed a high number of abnormal T4 values but binding indices were normal. The TSH-IRMA results were all normal. TSH-IRMA assays are rapid, easy to use and cheap. They remove the uncertainties in assessing thyroid function in CLD and may be the test of choice. PMID:3214117

  17. The metabolic syndrome in thyroid disease: A report from Nigeria

    Anthonia O Ogbera

    2012-01-01

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

    Introduction. The usual indication for a biliary-digestive bypass is the obstruction by a benign or a malignant stricture which can occur at the biliary- pancreatic confluence. Benign strictures mostly occur in the distal bile duct as a result of stones or chronic pancreatitis. Malignant obstructions involve mostly the distal end as a result of a ductal adenocarcinoma of the head of the pancreas, the ampulla of Vater and cholangiocarcinoma and can be virtually impossible to distinguish from e...

    Full Text Available Background: thyroid disease is one of the most prevalent medical conditions and thyroid cancer is the most common endocrine neoplasm. Thyroid reoperations are more common than it might seem.Objective: to establish the clinical and epidemiological characteristics of patients operated on for colloid goiter undergoing reoperation for recurrent thyroid disease.Methods: a case-series study was conducted at the León Cuervo Rubio Clinical-Surgical Hospital in Pinar del Rio. The sample included all patients (n = 29 who underwent thyroid operation and were reoperated on for recurrent thyroid disease in 2010, 2011 and 2012. The information was obtained from medical records and the register of histopathological diagnoses.Results: most patients (27.6% were in the 40-49 age group and females (79.3% were most affected. Recurrence was observed 5 to 9 years after surgery. Mixed nodules (55.2% followed by cysts (17.2% were the most frequent ultrasound diagnoses. Recurrent thyroid disease was malignant in 9% of patients.Conclusions: patients reoperated on for thyroid disease were mostly females in the fourth and fifth decade of life. The disease recurred in a period of 10 years after the first surgery in a greater number of cases. Follicular-patterned lesions, colloid goiter and cancer were the most common histologic diagnosis.

  1. The solitary thyroid nodule: diagnosis and management of malignant disease

    Energy Technology Data Exchange (ETDEWEB)

    Lawson, W.; Biller, H.F.

    While few solitary thyroid nodules are carcinomatous, it is essential to identify and preferentially select those that are for surgery. Clinical, biochemical, serologic, radiographic, scintigraphic, sonographic, biopsy, and even therapeutic evaluation may be necessary to choose those patients with the greatest probability of malignancy. The benefits and limitations of each diagnostic modality are discussed, and the importance of fine-needle aspiration is stressed. After the operative confirmation of malignancy, the prognosis in any given case depends on 1) the histologic type of the neoplasm, 2) its size and extent, 3) the presence of angioinvasiveness, 4) the tendency toward multicentricity of the lesion, 5) the age and sex of the patient, and 6) whether distant metastases are present. These factors influence the extent of surgery required for well-differentiated carcinomas. Meticulous dissection and preservation of the recurrent laryngeal nerves and the parathyroid glands along with their blood supply are important if total thyroidectomy for papillary carcinoma is to be employed with an acceptable operative morbidity to optimize survival. The value of the adjunctive use of thyroid hormone and radioactive iodine is also discussed. Finally, the clinical behaviors and treatments of undifferentiated carcinomas, sarcomas, lymphomas, and neoplasms metastatic to the thyroid gland are reviewed.

    Objective. Aim of the study was to determine the prevalence of autoimmune thyroid disease, persistence of antithyroid antibodies, effect of gluten-free diet, and long-term outcome of thyroid function in pediatric patients with celiac disease (CD). Methods. 67 patients with CD aged from 1 year to 16 years were screened for thyroid antithyroperoxidase, antithyroglobulin and anti-TSH receptor antibodies, serum free triiodothyronine, free thyroxine, and thyroid-stimulating hormone (TSH) at diagnosis and during follow-up. Results. None of the patients had antithyroid antibodies at diagnosis. Antithyroid antibodies became positive in 16.4% of the patients (11/67) 2 to 3 years after the diagnosis of CD. Clinical hypothyroidism was observed only in 3 of 11 CD patients with positive antithyroid antibodies (27.2%). The antithyroid antibodies positive and negative patients did not differ significantly according to compliance to GFD (P > 0.05). A statistically significant difference was observed only in age, in which the patients with positive antithyroid antibodies were younger than the patients with negative antithyroid antibodies (P = 0.004). None of the patients had any change in their thyroid function and antibody profile during their follow-up. Conclusion. Antithyroid antibodies were detected in younger pediatric patients with CD and the prevalence of antithyroid antibodies did not correlate with the duration of gluten intake. PMID:25788942

    Background There are increasing numbers of patients who survive more than one year after liver transplantation.Many studies have focused on the early mortality of these patients.However,the factors affecting long-term survival are not fully understood.This study aims to evaluate prognostic factors predicting long-term survival and to explore measures for improving the survival outcomes of patients who underwent liver transplantation for benign end-stage liver diseases.Methods The causes of late death after liver transplantation and potential prognostic factors were retrospectively analyzed for 221 consecutive patients who underwent liver transplantation from October 2003 to June 2008.Twenty-seven variables were assessed using the Kaplan-Meier method,and those variables found to be univariately significant at P <0.10 were entered into a backward step-down Cox proportional hazard regression analysis to identify the independent prognostic factors influencing the recipients' long-term survival.Results Twenty-eight recipients died one year after liver transplantation.The major causes of late mortality were infectious complications,biliary complications,and Hepatitis B virus recurrence/reinfection.After Cox analysis,the five remaining co-variables were:age,ABO blood group,cold ischemia time,post-infection region,and biliary complications.Conclusions The major causes of late mortality were infection,biliary complications and Hepatitis B virus recurrence/reinfection.Five variables (Age,ABO blood group,cold ischemia time,infection,and biliary complications) had significant impacts on patient survival.

  11. Radioiodine therapy for Plummer's disease based on the thyroid uptake of technetium-99m pertechnetate

    International Nuclear Information System (INIS)

    The aim of this retrospective study was the evaluation of a TcTUs (global technetium-99m pertechnetate thyroid uptake under suppression)-based approach in 370 patients with thyroid autonomy (Plummer's disease) treated by radioiodine therapy (RIT) under standardised conditions. The analysis included 370 patients (309 females, 61 males; mean age 64±11.6 years) treated for thyroid autonomy [unifocal (UFA), 36.8%; multifocal (MFA), 55.7%; disseminated (DISA), 7.6%]. During RIT all patients were under thyroid suppression (TSH0.5 μU/l and/or TcTUs4 μU/ml). A dose of 350-450 Gy to the autonomous tissue resulted in a success rate of 97% in the UFA group and 81% in the MFA/DISA group. Decrease in total thyroid volume and TcTUs did not differ significantly between successfully treated patients and patients with persistent autonomy. Multivariate analysis of all 370 patients identified four independent factors that negatively influenced the therapeutic success: high pretherapeutic thyroid volume (P=0.0001; odds ratio: 1.017), high pretherapeutic TcTUs values (P=0.0001; odds ratio: 1.378), multifocal/disseminated autonomy (P=0.0056; odds ratio: 3.245) and low target dose (P=0.017; odds ratio: 0.997). It is concluded that the high success rate in the treatment of UFA indicates the concept of TcTUs-based RIT to be valid, but that in the therapy of MFA/DISA the target se has to be corrected if the total thyroid volume exceeds a critical threshold.

  13. Diffuse Sclerosing Variant of Papillary Thyroid Carcinoma: a Histological Type With Difficult Diagnosis

    International Nuclear Information System (INIS)

    The papillary thyroid carcinoma is the most frequent thyroid neoplasm and usually it is a non aggressive tumor; nevertheless, some histological variants such as the diffuse sclerosing variant are more aggressive producing locoregional invasion and distant metastasis. This specific variant challenges the pathological diagnosis since the architectural and cytological characteristics might be confusing, particularly regarding benign lesions such as the lymphocytic thyroiditis. We present a case report of a patient at the National Cancer Institute of Colombia with a lung metastasis from a diffuse sclerosing papillary thyroid carcinoma. The difficulties for diagnosis, for both clinical and pathology experts, are illustrated as well as their relevance for determining the biological course of the disease.

  14. There is no Gradient of TSH Receptor Antibody Activity Between Thyroidal and Peripheral Venous Blood in Patients with Graves' Disease

    International Nuclear Information System (INIS)

    Thyrotropin binding inhibitory immunoglobulin (TBII) and thyroid stimulating antibody (TSAb) activities were measured in the thyroidal and peripheral venous blood samples at the time of subtotal thyroidectomy from twenty one patients with Graves' disease prepared for surgery with antithyroid drugs. There was no difference in TBII and TSAb activities between thyroidal and peripheral blood samples. These findings were regarded that while intrathyroidal lymphocytes are major site of thyrotropin receptor antibody (TRAb) production, similar levels are found in thyroidal and peripheral veins and that this in vive study cannot exactly ascertain the TRAb producing site.

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

  16. Guideline for in vivo- and in vitro procedures for thyroid diseases. Version

    International Nuclear Information System (INIS)

    The version 2 of the guideline for diagnostic standards of thyroid disorders is an update of the guideline published in 1999 and describes standards of in vitro and in vivo procedures. The following statements are modified: In vitro procedures: When measurement of the TSH-receptor antibodies is indicated, the guideline recommends the use of a second generation assay (recombinant human TSH-receptor as antigen). The functional assay sensitivity for the measurement of thyroglobulin should reach a value ≤1 ng/ml. Moleculargenetic tests (RET proto-oncogen) are indicated in patients with a newly diagnosed medullary thyroid cancer and in the relatives of patients with hereditary medullary thyroid cancer. In vivo procedures: The sonographic examination should use a probe with a frequency of at least 7.5 MHz. Indications for the thyroid scintigraphy: nodule size ≥1 cm in diameter, autonomous goitre/nodule with clinical or subclinical hyperthyroidism, necessity of a differentiation between Graves' disease and chronic lymphocytic thyroiditis, therapy control after a definitive treatment and - in individual cases - the follow-up of untreated autonomous nodules.

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

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

  20. Study of the hypothalamic - hypophyseal - thyroid axis by the administration of TRH to Chagas' disease patients

    International Nuclear Information System (INIS)

    The TSH and T3 response to synthetic TRH was evaluated in two groups of patients: normal and with Chagas' disease, from the urban area of Sao Paulo (Brazil). Plasma T4, PBI and TSH values were within the normal range, when compared with those found in the controls: So were the thyroid uptakes of 2 and 24 hours; the basal levels of T3 where within the normal range except in three subjects whose values were higher than normal. After TRH administration the amount of TSH secretion in patients with Chagas' disease was increased when compared to normal ones, while T3 secretion was unaltered. It is suggested that in the Chagas' disease there is an increase in the pituitary TSH, while the thyroid reserve is preserved. This increase could be due to a difference in the regulation rate of TRH, which is determined by the neuronal degeneration caused by the disease itself. (author)

  1. The influence of cyclosporin A on experimental autoimmune thyroid disease in the rat

    International Nuclear Information System (INIS)

    Female PVG/c rats, thymectomised on weaning and given 4 courses of whole body irradiation to a total dose of 1000 rads, developed experimental autoimmune thyroid disease (EAITD) as assessed by histological evidence of thyroiditis and circulating levels of antithyroglobulin antibodies. Hypothyroidism resulted. Induction of the disease was associated with a highly significant fall in T lymphocyte numbers. Eight weeks after their last dose of irradiation the animals commenced treatment with cyclosporin A (10 mg/kg rat/day, intragastrically) and were treated for varying time intervals thereafter. The reversal of the T lymphocyte helper: suppressor ratio on cyclosporin A therapy was associated with a significant improvement in the disease process. The alterations in the T cell subsets and in the disease lasted only as long as the drug was administered and thereafter reverted towards that seen in the control groups of animals receiving no treatment

    Full Text Available Sarcoidosis is a systemic granulomatous disease of unknown etiology. In most cases, mediastinal lymph nodes and lung parenchyma are involved. In addition, the eyes, skin, abdominal organs, central nervous system or the joints might be involved during the course of the disease. Sarcoidosis has been found to be related with other autoimmune diseases such as thyroiditis. In this report, we present the case of a patient in whom hyperthroidism was found and Graves’ disease and papillary thyroid carcinoma were diagnosed while being investigated with a preliminary diagnosis of sarcoidosis. A 50-year-old male patient was admitted to our chest diseases clinic with the complaints of cough with colorless sputum, joint pain, weakness, weight loss (36 kgs, palpitations, tremor of the hands and pain in the right eye. Mediastinal lympadenopathy was detected on CT scan. Laboratory tests demonstrated hypercalcemia and low levels of parathyroid hormone (PTH. Eye examination revealed uveitis. Bronchoscopy was planned to confirm the diagnosis of sarcoidosis. Thyroid function test was performed and the patient turned out to have hyperthyroidism with high free T4 and low TSH levels. TSH receptor antibody titer was 71 U/L (0- 14 U/L. Ultrasonographic examination demonstrated enlarged thyroid gland and heterogeneous parenchyma with increased blood flow pattern. 4- and 24-hour radioiodine uptakes were 30% and 60%, respectively and scintigraphy findings were compatible with diffuse toxic goiter. On Hertel exophthalmometer, the measurements of the right and left eye were 23 and 24 mm, respectively. The diagnosis of Graves’ disease was made and thionamide therapy was started. Since active ophthalmopathy was present and the patient did not want to receive medical therapy for a long time, surgery was the best option for definitive therapy. The patient was prepared for the surgery with lugol solution (3x10 drops daily and after eutyroidism was achieved, bilateral total

    Background. Studies in several ethnic groups reported high incidence of elevated levels of immunoglobulin E (IgE) in patients with autoimmune thyroid diseases (ATD), especially in patients with Graves' disease. Objective. To study association between serum levels of IgE and thyroid stimulating hormone receptor antibodies (TRAb) in Albanian patients with ATD. Material and Methods. Study was performed in 40 patients with Graves' disease, 15 patients with Hashimoto's thyroiditis, and 14 subjects in the control group. The IgE levels were measured by immunoradiometric assay, whereas the TRAb levels were measured by radioreceptor assay. Results. In all groups of subjects the IgE levels were within reference values (<200 kIU/L). Significant difference in mean concentration of IgE was found between two groups of Graves' disease patients, and those with normal and elevated TRAb levels (22.57 versus 45.03, P < 0.05). Positive correlation was found between TRAb and IgE only in Graves' disease patients (r = 0.43, P = 0.006). Conclusion. In Albanian patients with ATD there is no elevation of IgE levels. This could be the result of low prevalence of allergic diseases in Albanian population determined by genetic and environmental factors. PMID:24959371

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

    Thyroid diseases(TD) can be induced by either deficient or excessive iodine intake. Universal Salt Iodization(USI) program has been implemented in China since 1995, to prevent iodine deficiency disorders (IDD). To evaluate the current conditions of TD and the role of USI, a multi-stage stratified random sampling scheme was used to perform a cross-sectional survey on the incidence of TD among participants in 6600 households in Zhejiang Province, a coastal area in China. Iodine nutrition status of the population was assessed by dietary iodine intake recall and urinary iodine concentration (UIC) of the participants, and TD were diagnosed by thyroid ultrasonography for 15122 participants and for 5873 participants by serum criteria for thyroid function(fT3, fT4, TSH, TRAb, TgAb, TPOAb; see Introduction for abbreviations). The median UIC of the surveyed population was 163μg iodine/L. From the participants 23.2% had UIChyperthyroidism, subclinical hyperthyroidism, hypothyroidism, subclinical hypothyroidism, Graves' disease and chronic lymphocytic thyroiditis was 0.5%, 0.6%, 0.6%, 7.8%, 0.2% and 0.3%, respectively. The proportion of several TD for participants with non-iodized salt intake was higher than that for participants with iodized salt intake. PMID:27259353

    Introduction: The prevalence of autoimmune thyroid disease (AITD) is 10–12% in the general population worldwide. Among various disorders co-existing with AITD, the concomitance of celiac disease (CD) with AITD results in poor absorption of thyroid medications and results in higher doses of the same. Institution of gluten-free diet (GFD) in this cohort helps reduce medication doses. Aim: To screen patients with AITD for the presence of celiac autoimmunity (CA). Materials and Methods: A total of 280 consecutive patients with AITD attending the thyroid Out-patient Department of a tertiary care hospital were screened for the presence of tissue transglutaminase antibodies (immunoglobulin A tissue transglutaminase). Those with a positive titer (but duodenal mucosal biopsy for the diagnosis of CD, followed by institution of GFD in confirmed cases. Results: Of a total of 280 (182 females and 98 males) patients with AITD screened, 24 (8.6%) turned out to be positive for CA. Of 24 (8.6%), 15 (8.24%) females and 9 (9.18%) males were positive for CA. There was no statistically significant difference in the thyroxine doses required for normalization of thyroid function and the weight of the patients in CA positive and CA negative patients. Conclusions: The prevalence of CD in patients with AITD is much greater than in the general population. This forms the basis for screening patients with AITD for presence of CD. PMID:26904476

  11. Late cardiac, thyroid, and pulmonary sequelae of mantle radiotherapy for Hodgkin's disease

    International Nuclear Information System (INIS)

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

    Full Text Available Abstract Background The autoimmune thyroid diseases (AITDs, comprising Graves' disease (GD and Hashimoto's thyroiditis (HT, appear to develop as a result of complex interactions between predisposing genes and environmental triggers. Susceptibility to AITDs is conferred by genes in the human leukocyte antigen (HLA and genes unlinked to HLA, including the CTLA-4 gene. Recently, an association to some estrogen receptor (ERα genotypes with breast cancer, hypertension, osteoporosis, generalized osteoarthritis, and some autoimmune diseases such as rheumatoid arthritis has been reported. We have analyzed a dinucleotide (TAn repeat polymorphism lying upstream of the human ERα gene in patients with AITDs and in normal subjects. Results Seventeen different alleles were found in 130 patients with GD, 93 patients with HT, and 190 control subjects. There was no significant difference in the distributions of ERα alleles between patients and controls. Conclusions The present results do not support an association between the ERα gene and AITD in the Japanese population.

    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/ PPAR{gamma} 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.

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

  20. Elastic Deformation Properties of Implanted Endobronchial Wire Stents in Benign and Malignant Bronchial Disease: A Radiographic In Vivo Evaluation

    International Nuclear Information System (INIS)

    Purpose: To evaluate the long-term mechanical behavior in vivo of expandable endobronchial wire stents, we imaged three different prostheses in the treatment of tracheobronchial disease. Methods: Six patients with bronchial stenoses (three benign, three malignant) underwent insertion of metallic stents. Two self-expandable Wallstents, two balloon-expandable tantalum Strecker stents and two self-expandable nitinol Accuflex stents were used. Measurements of deformation properties were performed during voluntary cough by means of fluoroscopy, at 1 month and 7-10 months after implantation. The procedures were videotaped, their images digitized and the narrowing of stent diameters calculated at intervals of 20 msec. Results: After stent implantation all patients improved with respect to ventilatory function. Radial stent narrowing during cough reached 53% (Wallstent), 59% (tantalum Strecker stent), and 52% (nitinol Accuflex stent) of the relaxed post-implantation diameter. Stent compression was more marked in benign compared with malignant stenoses. In the long term permanent deformation occurred with the tantalum Strecker stents; the other stents were unchanged. Conclusion: Endobronchial wire stents can be helpful in the treatment of major airway collapse and obstructing bronchial lesions. However, evidence of material fatigue as a possible effect of exposure to recurrent mechanical stress on the flexible mesh tube may limit their long-term use. This seems to be predominantly important in benign bronchial collapse

    Full Text Available Introduction. Developments in immunological and quantitative real-time PCR-based analysis have enabled the detection, enumeration, and characterization of circulating tumor cells (CTCs. It is assumed that the detection of CTCs is associated with cancer, based on the finding that CTCs can be detected in all major cancer and not in healthy subjects or those with benign disease. Methods and Patients. Consecutive men, with suspicion of prostate cancer, had blood samples taken before prostate biopsy; mononuclear cells were obtained using differential gel centrifugation and CPCs detecting using anti-PSA immunocytochemistry. Positive samples underwent further classification with anti-P504S. Results. 329 men underwent prostate biopsy; of these men 83 underwent a second biopsy and 44 a third one. Of those with a biopsy negative for cancer, 19/226 (8.4% had CPCs PSA (+ P504S (− detected at first biopsy, 6/74 (8.1% at second biopsy, and 5/33 (15.2% at third biopsy. Men with cancer-positive biopsies did not have PSA (+ P504S (− CPCs detected. These benign cells were associated with chronic prostatitis. Conclusions. Patients with chronic prostatitis may have circulating prostate cells detected in blood, which do not express the enzyme P504S and should be thought of as benign in nature.

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

    Objective: To investigate the clinical significance of serum thyroid stimulating hormone (TSH) receptor antibody (TRAb) levels and the antithyroid drug (ATDs) use in pregnant women with Graves′ disease in their neonatal thyroid function. Methods: The serum TRAb and T3, T4, FT3, FT4, TSH levels in 68 pregnant women with Graves′ disease and their newborns were detected by radio receptor assay (RRA) and electrical chemiluminescence immunoassay (ECLIA), respectively. Based on the maternal serum TRAb levels and the use of antithyroid drugs during pregancy, the newborns were divided into different groups. The incidence of neonatal thyroid dysfunction and its risk factors were analyzed.Results: The results showed the incidence of abnormal thyroid function of newborns was 29.4% (20/68). The proportion of neonatal thyroid dysfunction in women with high TRAb levels in the third trimester of pregnancy were significantly higher than these with normal TRAb (P<0.01). In 23 newborns whose mothers were normal in serum TRAb levels and took no ATDs during pregnancy, only one case had thyroid dysfunction within two weeks after birth, while in other 45 newborns whose mothers had a high level of serum TRAb and/or took ATDs during pregnancy, 19 developed thyroid dysfunction within two weeks after birth.Conclusion: Neonatal thyroid function depends on the balance between the transplacental TRAb and ATDs. TRAb measurement in pregnant women with Graves′ disease is of significance in evaluation of neonatal thyroid function. Elevated level of serum TRAb in the third trimester of pregnancy is a risk factor for neonatal thyroid dysfunction.

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

    Sialylation of cell components is an important immunomodulating mechanism affecting cell response to hormones and adhesion molecules. To study alterations in sialic acid metabolism in Graves' disease (GD) we measured the following parameters in various human thyroid tissues: lipid-bound sialic acid (LBSA) content, ganglioside profile, total sialyltransferase activity, and the two major sialyltransferase mRNAs for sialyltransferase-1 (ST6Gal I) and for sialyltransferase-4A (ST3Gal I). Fragments of toxic thyroid nodules (TN), nontoxic thyroid nodules (NN) and nontumorous tissue from patients with nodular goiter or thyroid cancer were used as a control (C). The LBSA content and sialyltransferase activity were the highest in the GD group (164 +/- 4.44 versus 120 +/- 2.00 nmoL/g, p = 0.005 and 1625 +/- 283.5 versus 324 +/- 54.2 cpm/mg of protein, p TSH-receptor antibody titer determined by the TRAK test. These results indicate that sialyltransferases expression and activity are increased in GD. Exact mechanism of this upregulation remains unknown, though one of possible explanations is the activation of the thyrotropin (TSH) receptor. PMID:16053379

  9. Radioimmunoassay of TSH subunits in thyroid diseases and endocrine opthalmopahty

    International Nuclear Information System (INIS)

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

    In this paper, we present an effective and efficient computer aided diagnosis (CAD) system based on principle component analysis (PCA) and extreme learning machine (ELM) to assist the task of thyroid disease diagnosis. The CAD system is comprised of three stages. Focusing on dimension reduction, the first stage applies PCA to construct the most discriminative new feature set. After then, the system switches to the second stage whose target is model construction. ELM classifier is explored to train an optimal predictive model whose parameters are optimized. As we known, the number of hidden neurons has an important role in the performance of ELM, so we propose an experimental method to hunt for the optimal value. Finally, the obtained optimal ELM model proceeds to perform the thyroid disease diagnosis tasks using the most discriminative new feature set and the optimal parameters. The effectiveness of the resultant CAD system (PCA-ELM) has been rigorously estimated on a thyroid disease dataset which is taken from UCI machine learning repository. We compare it with other related methods in terms of their classification accuracy. Experimental results demonstrate that PCA-ELM outperforms other ones reported so far by 10-fold cross-validation method, with the mean accuracy of 97.73% and with the maximum accuracy of 98.1%. Besides, PCA-ELM performs much faster than support vector machines (SVM) based CAD system. Consequently, the proposed method PCA-ELM can be considered as a new powerful tools for diagnosing thyroid disease with excellent performance and less time. PMID:22327384

    Incidence of unexpected diagnosis of thyroid carcinoma among operations on benign thyroid surgical diseases (nodular goiter and Graves' disease) was studied in 608 patients within 2008-2009 years in specialized clinic of endocrine surgery. In 56 (9.2%) patients the "incidental" thyroid carcinoma including 43 (77%) - papillary microcarcinoma were diagnosed in histological investigations. In 10 (18%) patients which were performed within the first postoperative week. Repeated surgery demonstrates increased risk of complication (damage of parathyroid glands, recurrent laryngeal nerves and other anatomic structures of neck) considering less favoring conditions for secondary operations, it is worth to implement wider indications to frozen section, radical primary operation (total thyroidectomy at multi-nodular bilateral goiter and Graves' disease), and also maximal complete examination prior to surgery.

  14. Relapse of Graves disease after medical therapy: predictive value of thyroidal technetium-99m uptake and serum thyroid stimulating hormone receptor antibody levels

    International Nuclear Information System (INIS)

    In 49 patients with Graves disease, the 20-min thyroidal uptake of /sup 99m/Tc and serum levels of thyroid stimulating hormone (TSH) receptor antibody were estimated at presentation and at intervals during a 1-yr course of carbimazole and triiodothyronine. In the 12 mo after cessation of therapy, 29 patients developed recurrent thyrotoxicosis. Thyroidal /sup 99m/Tc uptake had a poor predictive value for recurrence of thyrotoxicosis, both at presentation and during therapy. A very high level of TSH receptor antibody was present in seven patients at presentation, all of whom relapsed on withdrawing therapy. An abnormal value of TSH receptor antibody at the end of the course of medical therapy was present in 24/29 (83%) patients who relapsed and in 1/20 (5%) patients who remained euthyroid 1 yr after stopping antithyroid drugs

    Full Text Available ABSTRACT : Thyroid nodules are common in adults, with a reported prevalence of up to 50%. (1 – 5. Furthermore, 9% to 15% of nodules identified during clinical examinations are diagnosed as malignant (6 – 8. It is gen erally accepted that sonography and sonographically guided fine - needle aspiration cytologic examination are the modalities of choice for differentiating benign and malignant thyroid nodules (1 , 9 . Thyroid ultrasonography (USG is the major diagnostic moda lity for evaluating thyroid nodules. Using USG, a thyroid nodule appears as a nodular lesion within the thyroid gland that is distinguishable from the adjacent parenchyma. Several USG features, such as marked hypoechogenicity, irregular margin, micro calci fications, and a taller - than - wide shape have been introduced as potential predictors for the presence of thyroid malignancies. AIMS & OBJECTIVE : The aim of this study was to assess the accuracy of USG diagnosis for thyroid nodules. MATERIALS & METHODS: Th e present study was conducted in the Department of Radiodiagnosis, TMMC & RC, TMU, Moradabad. Patients under the study were referred from department of Surgery, Paediatrics, Medicine, ENT, Gynaecology and Obstetrics. Patients for the study were evaluated b y Clinical & Radiological examination. The total number of patients were 120. RESULT: On clinical examination, multiple nodules were found only in 17% of cases, whereas on USG, multiple nodules were found in 58%. 50% of clinically solitary nodules were d emonstrated to be multiple on USG. CONCLUSION: In conclusion, similar to the recent literature reviewed so far, for a large majority of patients, diagnosis changed after ultrasonography, so the results necessitate the use of ultrasonography, which is a non invasive method, as a complementary method to physical examination in the diagnosis of thyroid diseases, especially thyroid nodules.

    AIM: To investigate the prevalence of coeliac disease in a series of Turkish patients with autoimmune thyroiditis.METHODS: Sera from 136 consecutive patients with newly diagnosed autoimmune thyroiditis and 119 healthy blood donors were tested for IgA tissue transglutaminase antibody with enzyme-linked immunosorbent assay. Endoscopic mucosal biopsy from the second part of duodenum was performed in patients with positive antibody test.RESULTS: Eight patients (5.9%) and one control subject (0.8%) were positive for IgA tissue transglutaminase antibody (OR: 7.38, 95% CI: 0.91-59.85, P = 0.04). Six patients and one control agreed to take biopsies. Histopathological examination revealed changes classified as Marsh ma in one, Marsh n in one, Marsh I in two, and Marsh 0 in two patients with autoimmune throiditis, and Marsh I in one blood donor.CONCLUSION: Turkish patients with autoimmune thyroiditis have an increased risk of coeliac disease and serological screening may be useful for early detection of coeliac disease in these patients. Our findings need to be confirmed in a larger series of patients.

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

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

    Purpose A single surgeon skilled in conventional laparoscopic surgery used laparoendoscopic single-site surgery (LESS) to treat benign urological diseases. This study reports our surgical results and introduces a simple technique with tips based on our experience. Materials and Methods LESS surgery was performed on 116 patients by use of a homemade single-port device composed of an Alexis wound retractor and a powder-free surgical glove. Cases were 44 varicocelectomies (including 8 bilateral cases), 38 renal cyst marsupializations (including 3 bilateral cases), 26 ureterolithotomies (with 1 concomitant ureterolithotomy and contralateral renal cyst marsupialization), 4 prostatic enucleations, and 4 bladder rupture repairs. The mean patient age was 44.43±16.46 years (range, 11 to 76 years), and the male-to-female ratio was 87:29. Results In one ureterolithotomy case, LESS was converted to conventional laparoscopic surgery. The mean operative time was 87.03±45.03 minutes, the estimated blood loss was 61.90 ml (range, 0 to 2,000 ml), and the mean hospital stay was 3.03±2.12 days. Two patients underwent single-port transvesical enucleation of the prostate (STEP) requiring patient-controlled anesthesia. No patients developed major complications, and all patients were satisfied, with 75.86% expressing a high degree of satisfaction. Conclusions We report successful treatment outcomes for LESS in 116 cases of benign urological disease. Our findings suggest that LESS can replace conventional laparoscopy. PMID:22468211
