Despite sufficient iodine supply, goiter continues to be of considerable surgical significance in formerly endemic countries. It now appears that iodine deficiency and increased thyrotropin stimulation are not the only causes of goiter. Xenotransplantation of human thyroid tissue onto nude mice allowed study of the regulation of growth and function in human goiter tissue. Grafts of human thyroid tissue growing in nude mice could be shown to react to endogenous mouse thyrotropic stimulation and suppression. 131 I autoradiographs of xenotransplanted goiter tissue showed as marked a heterogeneity as did the original goitrous tissue prior to transplantation. There was no firm correlation between the morphologic appearance of a follicle and its iodine metabolism. Scintigraphically cold and hot goiter tissue differed from each other quantitatively but not qualitatively; i.e., both hot and cold tissue were composed of metabolically active and nonactive follicles. Iodine organification was not completely suppressible by thyroxine treatment; this indicates autonomous functional activity. The distribution of proliferating tissue labeled by 3 H-thymidine did not parallel the distribution of functionally active tissue labelled by 131 I. Thyroxine treatment did not completely inhibit 3 H-thymidine incorporation, indicating autonomous growth. Thus, our pathogenetic concept of goiter formation is based on three mainstays: (1) goiter heterogeneity, (2) autonomy of growth and function, and (3) dissociation of growth and function in human goiter tissue. Thus, the surgeon dealing with goiter ought to remove all pathologically altered tissue, i.e., nodular tissue, irrespective of its appearance on scintiscans

Full Text Available Background : Many authors have claimed that hyperthyroidism protects against thyroid cancer and believed that the incidence of malignancy is lower in patients with toxic multinodular goiter (TMG than in those with non-toxic multinodular goiter. But in recent studies, it was reported that the incidence of malignancy with TMG is not as low as previously thought. Aim : To compare the thyroid cancer incidence in patients with toxic and non-toxic multinodular goiter. Settings and Design : Histology reports of patients treated surgically with a preoperative diagnosis of toxic and non-toxic multinodular goiter were reviewed to identify the thyroid cancer incidence. Patients having a history of neck irradiation or radioactive iodine therapy were excluded from the study. Materials and Methods : We reviewed 294 patients operated between 2001-2005 from toxic and non-toxic multinodular goiter. One hundred and twenty-four of them were toxic and 170 were non-toxic. Hyperthyroidism was diagnosed by elevated tri-iodothyroinine / thyroxine ratios and low thyroid-stimulating hormone with clinical signs and symptoms. All patients were evaluated with ultrasonography and scintigraphy and fine needle aspiration biopsy. Statistical Analysis Used : Significance of the various parameters was calculated by using ANOVA test. Results : The incidence of malignancy was 9% in the toxic and 10.58% in the non-toxic multinodular goiter group. Any significant difference in the incidence of cancer and tumor size between the two groups could not be detected. Conclusions : The incidence of malignancy in toxic multinodular goiter is not very low as thought earlier and is nearly the same in non-toxic multinodular goiter.

The present work aimed to further explore the therapeutic potential of Xing Qi Hua Ying Tang (XQHYT) by conducting a systemic clinical study in patients with goiter. Seventy-two patients with either multinodular or diffuse goiter were enrolled and randomly assigned into treatment group receiving XQHYT (n = 36) and control group receiving Hai Zao Yu Hu Tang (n = 36). Traditional Chinese Medicine Hospital of Shanxi. Patients were diagnosed multinodular goiter or diffuse goiter resulting from Qi stagnation. All patients took the extract twice a day (100 mL each time) for two courses of treatment, of which a single course lasted for 3 months. Before the treatment was commenced and after the completion of the treatment, general body checks, thyroid function test, and goiter size examination were performed. Scoring of the clinical symptoms using Chinese medicine symptomatology was also done. The symptom score of the treatment group was significantly lower than that of the control group (treatment group, 8.26 ± 2.62; control group, 10.02 ± 2.62; p < 0.05). Substantial reduction in goiter size was seen in 82.3% of XQHYT-treated patients, whereas in the control group only 67.7% of patients exhibited constricted goiter. When assessed by both the Chinese medicine criteria and goiter size, the overall effective rate of the treatment group was 91.2%, whereas that of the control group was only 67.7%. The difference was statistically significant (p < 0.05). XQHYT did not affect the normal functions of liver, kidney, and heart. For both groups of patients, their levels of thyroid-stimulating hormone, free T4 and free T3 were normal before the treatment, and were not affected by the treatment. XQHYT was shown to be a promising therapeutic regimen for the treatment of goiter. The herbal regimen ameliorated clinical symptoms of patients that were accompanied with reduction in the size of goiter.

A newborn infant with large bilateral cervical masses developed respiratory difficulties three days after birth. A congenital goiter was suspected and a biopsy was performed. Later information pointed to the ingestion of large amounts of inorganic iodine, during the pregnancy, by the asthmatic mother. Further investigation proved the goiter to be due to transient depression of peroxidase activity by the exogenous iodine. Within several days after birth, the infant's thyroid regained its full activity, the goiter disappeared, and the few signs of hypothyroidism subsided. (U.S.)

A Giant Euthyroid Endemic Multinodular Goiter with No Obstructive or Compressive Symptoms

Full Text Available Diffusely enlarged thyroid glands (goitres are becoming increasingly infrequent. However, in some geographical areas they are still relatively common and can cause compressive symptoms involving the trachea, oesophagus, and recurrent laryngeal nerve. Surgical treatment of diffusely enlarged thyroid glands requires a high level of expertise and may lead to severe complications. Here we present a case report of surgical treatment of an extremely enlarged thyroid gland, found in a 61-year-old female patient. The patient underwent surgery, and a thyroidectomy was performed. The resulting specimen weighed 4.7 kg (10.4 lbs. Histopathological examination revealed a multinodular goitre with multiple cysts and areas of haemorrhage and necrosis. Surgical excision can immediately resolve local symptoms and is often recommended when substernal extension is evident. To the best of our knowledge, this is the largest thyroid gland ever reported in the literature. Only experienced surgeons should treat large thyroid goitres. Ideally, large thyroid goitres should be treated before they reach a substernal component, otherwise any sudden growth in gland size could seriously compromise respiration.

In the present paper we present the consequences of an accidental occupational radiation exposure at a local hospital in Buenos Aires. Control at a local radiology service showed the lack of correct shielding in the X-ray equipment. The physicians and technicians (14 persons) exposed to radiation during 12 months were examined. The survey shows that: a) In 11 out of 14 radiation-exposed patients nodular goiter developed and an additional patient had diffuse goiter which means a goiter incidence of 85.7%; b) In 5 of the nodular goiter patients an increase in the size or the appearance of new nodules was observed along the follow-up period. No cancer was detected by FNA; c) Hypothyroidism was observed in 3/14 patients, and an additional patient had an abnormal TRH-TSH test, suggesting subclinical hypothyroidism; and d) Increased circulating antithyroid antibodies were found in one of the hypothyroid patients

Background: To determine the thyroid function tests and urinary iodine levels in women belonging to goiter endemic area. Study type and settings: Descriptive study conducted in women of goiter endemic area in Saggian Lahore. Subjects and Methods: Saggian Lahore is a goiter endemic area. A total of 293 women between the ages of 18-45 years residing in the area were clinically screened for goiter. Of them 73 women having goiter were recruited for the study. Information regarding demographic profile clinical presentation and physical examination of the goiter was recorded on a questionnaire. The goiter size was graded according to WHO, UNICEF and the International Council for the Control of Iodine Deficiency Disorder. About 5ml of blood sample was drawn from each women and run for thyroid function tests i.e. T3 T4 and TSH using Elisa kits (Human scientific Co. Germany). Urinary iodine was checked by chemical method. Results: Mean age of 73 women was 28.5 years. Marital status showed that 48(65.7%) were married and 25(34.3%) were unmarried. Visible diffuse goiter was seen in 56(77%) cases. Pressure symptoms as cough and shortness of breath was seen in 30(41%) and 31(42.5%) women respectively. Among the 73 women 24.6% (18 cases) took treatment for goiter. Adverse pregnancy outcome secondary to goiter was seen in 58% (28 cases) out of 48 married women. Thyroid function tests result showed that 72% (53 cases) were euthyroid, 18% (13 cases) were hypothyroid, and 10% (7 cases) were hyperthyroid. Urinary iodine levels showed that 99% women were iodine deficient. Conclusions: Thyroid functions do not indicate iodine deficiency in all cases of goiter, therefore, Urinary iodine levels need be estimated while investigating goiter cases. Policy message: Iodine deficiency should be diagnosed and treated on priority basis. (author)

Objective: To study goiter and thyroid dysfunction in female adolescents residing in Lahore referred to Centre for Nuclear Medicine (CENUM), Mayo Hospital for thyroid scanning and thyroid function tests. Design: Retrospective study of thyroid size, thyroid scan patterns and serum FT/sub 4/ and TSH levels. Setting: Centre for Nuclear Medicine (CENUM), Mayo Hospital, Lahore. Patients: 350 female adolescent referred during September 2002 to April 2003. Main outcome measures: adolescent goiter, thyroid nodules, hyperthyroidism, hypothyroidism, Graves' disease, toxic multi nodular goiter. Results: Among 350 adolescents 212(60.6%) had goiter of various grades mostly visible. Among goiterous patients 136(64.2%) had diffuse and 76 (35.8%) had nodular presentation. The number of patients with solitary nodular goiter (20.7%) was more than multi nodular goiter (15.1%) and number of patients with solitary cold nodule (16.5%) was more than functioning nodule (4.2%). The incidence of biochemical thyroid dysfunction, both overt and subclinical, was detected in 42(19.8%) patients and was significantly more frequent in patients with nodular than diffuse presentation (29% VS 14.7%; p<0.001) and in multinodular than solitary nodular goiter (p<0.005). More than 80% of the patients with solitary nodular goiter were euthyroid. Simple goiter was detected in 116(54.7%), Graves' disease in 5(2.4%) and toxic multinodular goiter in 4(1.9%) patients. Overall incidence of hypothyroidism was more than double as compared to hyperthyroidism. Incidence of nodularity and hypothyroidism was more in large goiter but duration of goiter was not significant in promoting nodularity. Conclusion: Goiterous adolescents need urgent attention because they don't have just diffuse hypertrophy with normal thyroid function. Many are afflicted with dysfunction and nodularity, particularly solitary cold nodule bearing risk of thyroid malignancy. (author)

Full Text Available Bocio es todo aumento de volumen de la glándula tiroidea. Su patogenia está dada fundamentalmente por una disminución en los niveles circulantes de hormonas tiroideas, con el consiguiente aumento de los niveles de hormona tirotropa que provocan hipertrofia e hiperplasia de las células foliculares y dan lugar al aumento de volumen de la glándula. Se clasifica en bocio simple, nodular y puberal. Según la OMS se clasifica por grados desde el 0 al III, y de acuerdo con la etiología en endémico y esporádico. El diagnóstico se realiza por el interrogatorio, el examen físico y se apoya en estudios complementarios: los niveles de TSH y el ultrasonido. El tratamiento depende de la etiología, la edad y el momento fisiológico de aparición. Consta de 5 pilares: preventivo, conservador o expectante, medicamentoso, quirúrgico y el uso de radioyodo. El seguimiento es clínico, apoyado en la ecografía y estudios de la función tiroidea, durante el primer año cada 6 meses, y que, si no hay modificación, se repiten anualmente.Goiter is any increase of volume of the thyroid gland. The pathogenesis is mainly due to a reduction of the circulating levels of thyroid hormones, with the resulting rise of thyrotropin hormone levels that cause hypertrophy and hyperplasia of the follicular cells and give rise to the increased volume of the gland. It is classified as simple, nodular and pubertal goiter. According to the WHO, the degree-based classification goes from 0 to III, and according to etiology, it may be endemic and sporadic. The diagnosis of goiter is based on the questioning of the patient, the physical exam and supplementary studies as TSH levels and ultrasonography. The treatment depends on the etiology, the age of the patient, and the time of onset and has five pillars: preventive, preservative or expectant, pharmacological, surgical and the use of radioiodine. The clinical follow-up supports on echography and thyroid function studies every

Naturally occurring goiter cases are described in 2 newborn Arabian foals whose mares were supplemented with excess iodine during the final 24 w of the pregnancy. Six nursing foals and 2 mares were also affected clinically with thyroid hypertrophy. At least 12 times the maximum tolerable level of iodine supplementation was given, as the daily iodine intake for each mare was 299 mg. The prevalence of goiter cases was 2 and 9% in the mares and foals, respectively.

The incidence of abnormal fetal thyroid function with maternal Grave's disease is about 2-12%. The development of larger fetal goiters can complicate labor and precipitate life-threatening airway obstruction at delivery. A case is presented of a large stable goiter confirmed by sonography, which unexpectedly resolved by the time of parturition. A 3 x 6 cm fetal goiter was detected at 34 weeks gestation in a mother treated with propylthiouracil for Grave's disease. A repeat sonogram at 36 weeks showed no change in goiter size. Umbilical blood sampling showed the fetus to be markedly hyperthyroid. Planned Cesarean section took place 11 days after the final sonogram. A multi-disciplinary operative team was present including the Otolaryngology service with equipment for emergency intubation, bronchoscopy and tracheotomy. Upon delivery, the infant had no evidence of goiter and no airway compromise. Fetal goiter is a rare entity, and recent advances in the field of maternal-fetal medicine have enabled intra-uterine diagnosis and treatment of such conditions. A review of published case reports demonstrates two trends in treated fetuses: preterm progressive resolution of the goiter, or delivery with gross evidence of goiter. This reported case is unique, as a persistent goiter resolved completely in less than 2 weeks. Otolaryngologic response to and management of potential congenital airway compromise is discussed.

This study was designed to update the existing information concening goiter prevalence and iodine deficiency disorders in omdurman city and to compare the effects of thyroxine versus iodine in the treament of simlpe goiter. Thyroxine in different doses is commonly used in treatment of simple goiter in Sudan. The goiter survey was conducted in Omdurman secondary school for girls (Khartoum state). Of the goitrous subjects 99 girls were selected to participate in the treament protocol. A control group of 54 non-goitrous subjects from the same school were also included. The goitrous subjects were divided randomly into two groups receiving either daily dose of 100 μg thyroxine for six months or a single dose of 400 mg of oral iodine in the form of iodized oil. Blood and urine samples were collected from the goitrous and control group and recollected from the goitrous subjects every six weeks for six months. Goiter size was assessed at 3,6 and 14 months after the commencement of the treament. Blood samples were analyzed for serum level of T4,T3 and TSH using sensitive radioimmunoassay techniques. Urine samples were analyzed for urinary iodine excretion. Goiter was found in 139 students out of 1034, (13.4%). They were all euthyroid with simple diffuse goiter.T4 in the goitrous group (93.3±26.9 nmole /L (mean±SD)) was significanty lower than in the control group (106.4±18.2nmole/L,p<0.05). T3 was significantly higher in the goitrous (1.6±0.4 nmole/L) than in the control group (1.3±0.3 nmole/L,p<0.05) while there was no significant difference in the mean serum TSH or urinary iodine excretion between the two groups. More than 70% of the goitrous and the control subjects excreted 2 μg 1 / dI or less. Of the subjects treated with thyroxine 87.8% showed complete disappearance or definite regression of the goiter size compared with 90% of those received iodine after the treament.(Author) =

Roentgenoendovascular functional thyroidectomy was used to suppress the pathological activity of the thyroid in postoperative recurrent goiter. The method consists in vascular isolation of hyperplastic stump of the thyroid by catheterization of the left and right thyroid arteries, followed by their material occlusion. For embolization, a wide spectrum of nonlyzed synthetic, organic, and inorganic materials were used. The results of roentgenoendovascular functional thyroidectomy in 14 patients with postoperative recurrent goiter are analyzed. The advantages of roentgenoendovascular occlusion of the thyroid arteries before subtotal thyroidectomy are emphasized. A stabile clinical and hormonal remission and reduction of the thyroid in size to stage 1 were observed during three years following roentgenoendovascular intervention [ru

We describe two cases of fetal goiter in women with no history of thyroid disease. Diagnosis of fetal goiter during antenatal care was made by ultrasound and MRI. Congenital hypothyroidism was confirmed by fetal blood sampling that was treated with weekly intra-amniotic injections of L-thyroxin. One fetus was initially treated with four weekly intra-amniotic injections of 200 mu gms of L-thyroxin, later increased to 400 mu gms. The other fetus was treated with only three weekly intraamniotic injections of 400 mu gms of L-thyroxin. Therapeutic response was monitored by repeated ultrasound and MRI along with fetal blood sampling. At birth, none of the babies had goiter and were put on oral thyroxin. Post-natal studies were suggestive of congenital hypothyroidism due to dyshormogenesis. No abnormality was detected at follow-up. These cases highlight the role of intra-amniotic thyroxine in management of fetal hypothyroidism with goiter. (author)

This study assesses the distribution of goiter in the Kalutara District, Sri Lanka in order to find causative factors for the occurrence of goiter even after the salt iodization. A questionnaire survey was conducted at the household level and at the same time iodine and selenium levels of the water sources were analyzed. Questionnaire survey results indicated the highest numbers of goiter patients in the northern part where the lowest were found in the southern sector which may be due to the presence of acid sulfate soils. Females were more susceptible and it even showed a transmittance between generations. Average iodine concentrations in subsurface water of goiter endemic regions are 28.25 ± 15.47 μg/L whereas non-goiter regions show identical values at 24.74 ± 18.29 μg/L. Surface water exhibited relatively high values at 30.87 ± 16.13 μg/L. Endemic goiter was reported in some isolated patches where iodine and selenium concentrations low, latter was <10 μg/L. The formation of acid sulfate soils in the marshy lands in Kalutara district may lead to transformation of biological available iodine oxidation into volatile iodine by humic substances, at the same time organic matter rich peaty soil may have strong held of iodine and selenium which again induced by low pH and high temperature were suggested as the instrumental factors in the endemic goiter in Kalutara district. Hence, geochemical features such as soil pH, organic matter and thick lateritic cap in the Kalutara goiter endemic area play a role in controlling the available selenium and iodine for food chain through plant uptake and in water.

Nuclear-medical local diagnosis of the enthyreotic (bland) goiter

The recommendations made by the Goiter Section of the German Society for Endocrinology and by the Task Force on Short-lived Radionuclides for Medical Applications in the USA on the in-vivo application with radionuclides on the goiter are almost completely identical. They can be summarized as follows: a) in-vivo-radionuclide examinations are to be carried out only if there is an indication to do so. b) The radionuclide with the lowest radiation exposure should be applied (e.g. /sup 123/I, /sup 99/sup(m)Tc). c) /sup 131/I is being applied in a few exceptional cases only, but not for the routine scintiscanning of the bland goiter. As camera scintiscanning has been technically improved during the last years, the gamma camera might increasingly prevail over the scanner for thyroid scintiscanning. Taking into consideration possible 'pitfalls' in thyroid scintiscanning helps to avoid false diagnoses.

The pathogenetic significance of low iodine intake in non-endemic goiter

Harriet, D.P.; Rigshospitalet, Copenhagen

1977-01-01

The blood inorganic iodine concentration (BII), the radioiodide clearance and the absolute iodine uptake (AIU) were determined in 27 patients with simple goiter and in 21 controls. The purpose was to evaluate the pathogenetic significance of low iodine intake for the formation of sporadic goiter. An early thyroid radioiodide clearance was measured by 132 I (5-30 min post injection), and the BII values were bases on the specific activity of I in saliva. The median BII levels of patients and controls were 1.1 and 1.5 μg/l respectively, and the urinary iodine excretion 67 and 79 μg/day respectively, the difference was not significant. The radioiodide clearance was above the normal range in 13 out of 27 patients, and 16 of 27 patients had elevated or high normal AIU values. These patients included 7 out of 9 patients with diffuse, shortlasting goiter; the AIU of those with nodular goiter ranged from slightly subnormal to elevated. Only one exhibited a typical iodine deficiency pattern of very low BII, high radioiodide clearance and normal AIU. (orig.) [de

The risks of thyroid dysfunction after iodinated contrast media exposure in patients with euthyroid nodular goiter are largely unknown. This observational, retrospective cohort study included a random selection of one million people in Taiwan. All patients with iodinated contrast media exposure during this study period were selected. Patients with euthyroid nodular goiter were identified as cases, while patients without thyroid nodule were selected as controls. We followed these patients until the first event of thyroid dysfunction including hyperthyroidism or hypothyroidism after iodinated contrast media exposure. A total of 334 cases and 2672 matched controls were selected in this study. The mean age of cases and controls were 58.6 and 58.4 years old, and mean follow-up durations were 2.1 and 2 years respectively. After adjustment, patients with euthyroid nodular goiter had a higher risk of thyroid dysfunction (hazard ratio 5.43, [confidence interval (CI) 3.01-9.80]) compared with controls after iodinated contrast media exposure. In the subgroup analysis, the risks of hyperthyroidism and hypothyroidism in cases compared with controls were 5.77 [CI 2.64-12.62] and 4.95 [CI 2.15-11.40] respectively. Half of the euthyroid nodular goiter cases developed thyroid dysfunction within one year after iodinated contrast media exposure. Interestingly, all thyroid-related comorbidities and drug prescriptions did not increase the risk of thyroid dysfunction. Presence of euthyroid nodular goiter was associated with higher risk of thyroid dysfunction including hyperthyroidism and hypothyroidism after iodinated contrast media exposure.

2014-01-01

Thyroid hemiagenesis is a rare form of thyroid dysgenesis characterized by an absence of half of the thyroid gland. Developmental hemi-thyroid anomalies can result from either an abnormal descent or an agenesis of one lobe of the thyroid gland. We report a case of a 40-year-old woman with history of a longstanding gradually progressive thyroid swelling without any complication. An ultrasonographic examination diagnosed the absence of the left thyroid lobe and enlargement of the right lobe, which was confirmed on a computed tomography (CT) angiogram and a radionuclide scan of the neck. A cytological examination showed nodular goiter with cystic degeneration. Right subtotal thyroidectomy was performed and histopathological examination confirmed adenomatous goiter with degenerative changes. We report the rarity of the condition and emphasize the role of a comprehensive radiological, cytological, and radionuclide algorithm for an accurate preoperative diagnosis and subsequent management

The rare presentation of hyperthyroidism caused by an intrathoracic goiter with a normal-sized cervical thyroid gland is described. The toxic intrathoracic goiter demonstrated avid uptake of [ 131 I] and [99mTc]pertechnetate, with comparatively faint isotopic accumulation seen in the cervical thyroid. A chest roentgenogram and radioisotope scan should be mandatory in cases of hyperthyroidism having no cervical thyroid enlargement to explore the possibility of a toxic intrathoracic goiter

The results were correlated with clinicomorphological features. All patients were women (33–82 years. The preoperative diagnosis was thyroid goiter or nodule. Treatment consisted in thyroidectomy and lobectomy (3 and 2, resp.. Microscopy showed sporadic nodular goiter. Malformative blood vessels and vascular calcifications were seen in intra- and extrathyroid location (5 and 3, resp.. The number and size of HBFs (total: 28 ranged between 1 and 23/thyroid gland (one bilateral and 1 and 10 mm, respectively. Twelve HBFs were in contact with the thyroid capsule. Most were extranodular (21, versus 6 intranodular. The medical history was positive for dyslipidemia, hyperglycemia, renal dysfunction, and hyperuricemia (2, 3, and 3 cases and 1 case, resp. without any parathyroid abnormality. In conclusion, thyroid HBF may be characterized by subcapsular or extranodular location, various size (usually ≥2 mm, and vascular calcifications and malformations. Features of metabolic syndrome and renal dysfunction may be present, but their exact role in the pathogenesis of HBFs remains to be elucidated.

In 2,790 scintiscans of the thyroid gland the distribution of cold, cool, warm and hot nodules and of diffuse goiters was assessed. In 276 scintiscanned patients who underwent operation, classification based on the following criteria: nodule type, palpation, malignancy rate, histology, age and sex. In addition, the occurrence of hyper- and hypothyreosis was investigated. For cold nodules the malignancy rate was 13.7%, for cool nodules 7.7%, for warm nodules 2.7%, and for diffuse goiters 7%; hot nodules didn't show malignant growth. In 9% of all operated preparations malignant degenerations were found; the removed nodular goiters comprised 9.3%. Among all nodules the incidence was 2.2%; 4.6% of all cold nodules were malign. In 20% of all patients with cancer metastases were found; their most frequent localisations were the regional lymphatic nodes. Histologically papillary and follicular carcinomas resulted to be the most frequent carcinomas (36% each); the incidence of anaplastic carcinomas was 20%. Medullary carcinoma and sarcoma were diagnosed once each. In females benign nodules occured more than four times, diffuse goiters and cold malignomas almost three times as much as in males. In both sexes the most benign modules were found between the 50th and 70th year of life, and particularly in the 7th decade of life. Toxic adenomas occurred particularly in women up to 35 years and at the beginning of the 8th decade of life. (orig.) [de

Full text: Introduction: Obstructive sleep apnoea syndrome (OSAS) is associated with a large number of predisposing factors (obesity, nasal obstruction, adenoid hypertrophy, macroglossia etc.). In addition to these factors goiter and hypothyroidism have been reported to be associated with OSAS. Objectives and tasks: In our case with retrosternal goiter, values of OSAS before and after thyroidectomy were shown. Materials and methods: Seventy-two years old, BMI: 26,8 kg/m 2 , female patient was admitted our hospital because of complaints to stop breathing during sleep, snoring, morning headache and daytime drowsiness. Results: Thorax CT and ultrasonography of thyroid shown retrosternal goiter and left tracheal deviation. Severe OSAS was diagnosed by polysomnography (PSG). Thyroid function tests were normal. Apneahypopnea index (AHI) was 63,1/h. Patients was performed 7 cm H 2 O nasal continuous positive airway pressure (gvrnCPAP). AHI was 11,4/h under nCPAP. One month after OSAS diagnosis the patient underwent thyroidectomy operation. Pathological examination was reported as multinodular GOITER. In postoperative period CPAP treatment couldn't continue, because patient was not compliant. In postoperative 8-th weeks, PSG was performed; AHI was 34,8/h. The patient's weight and BMI didn't change. Conclusion: In our case, despite absence of continued CPAP treatment after thyroidectomy, symptoms and PSG values improved partially. As a result of these findings, especially, compression of upper airway and deterioration of venous circulation of patients with large goiter may lead to an increase in OSAS symptoms. During patients with OSAS are treated with CPAP, goiter needs to be investigated

Endemic goiter is a health problem in many areas of the world; in some areas the disease is so severe that cretinism and other defects are found. In many areas geographic, economic, and other factors prevent the use of iodized salt as a preventive measure. Field studies were begun in 1966 to determine the feasibility and effectiveness of parenteral administration of iodized oil in goiter prevention. Studies were carried out in Ecuador and Peru. In Ecuador 2 villages were chosen in which the prevalence of goiter was about 60%; in Peru 3 villages were chosen where incidence was about 50%. Prevalence of goiter decreased for 20 months during the study but then began to rise again with the maximum reduction seen up to age 18 and minimal reduction after 40 years of age. The control groups in the study experienced only slight decreases in rate of incidence. Cretinism has not yet appeared among the progeny of the population injected with iodized oil but several instances have appeared in control groups. The use of iodized oil as a public health procedure for the prevention of endemic goiter and its associated defects is an acceptable measure in regions where salt iodization cannot be done.

Iodine is a key ingredient in the synthesis of thyroid hormones and also a major factor in the regulation of thyroid function. A local reduction of iodine content in follicular lumen leads to overexpression of local thyroid-stimulating hormone receptor (TSHr), which in turn excessively stimulates the regional thyroid tissue, and result in the formation of nodular goiter. In this study, we investigated the relationship between iodine content and sodium iodide symporter (NIS) expression by using the clinical specimens from patients with nodular goiter and explored the pathogenesis triggered by iodine deficiency in nodular goiter. In total, 28 patients were clinically histopathologically confirmed to have nodular goiter and the corresponding adjacent normal thyroid specimens were harvested simultaneously. Western blot and immunohistochemistry were performed to assay NIS expression and localization in thyrocytes of both nodular goiter and adjacent normal thyroid tissues. NIS expression mediated by iodine in follicular lumen was confirmed by follicular model in vitro. Meanwhile, radioscan with iodine-131were conducted on both nodular goiter and adjacent normal thyroid. Our data showed that NIS expression in nodular goiter was significantly higher than that in adjacent normal tissues, which was associated with low iodine in the follicular lumen. Abnormal localization of NIS and lower amount of radioactive iodine-131 were also found in nodular goiter. Our data implied that low iodine in the follicular lumen caused by cytoplasm mis-localization of NIS may induce nodular goiter.

To explore the changes of goiter prevalence of children living in areas with high iodine in drinking water after removing iodized salt from their diet. Three towns with median water iodine of 150 - 300 μg/L were selected randomly in Hengshui city of Hebei province of China. A total of 452 and 459 children in the 3 towns were randomly selected to measure thyroid volume by ultrasound before and after removing iodized salt, respectively. Their goiter status was judged using the criteria of age-specific thyroid volume recommended by the WHO. After removing iodized salt, the overall goiter prevalence in the three towns significantly decreased from 24.56% (111/452) to 5.88% (27/459) (P < 0.01). The goiter prevalence in 8, 9 and 10 year-old children decreased respectively from 33.70% (31/92), 23.32% (45/193) and 20.96% (35/167) to 6.10% (10/164), 5.52% (9/163) and 6.06% (8/132). The goiter prevalence in boys and girls decreased from 27.05% (66/244) and 21.63% (45/208 ) to 6.66% (15/226 ) and 5.15% (12/233), respectively. The decreases in children's goiter prevalence across gender and age group were all significant. Children's goiter prevalence decreased significantly after removing iodized salt from their diet for about one and half years in the HIA in Hebei province.

Euthyroid goiter is frequent for general practitioners (GPs) and endocrinologists (ENDOs). It may induce complications especially in elderly subjects when it becomes nodular and hyperfunctional whereas in young subjects prevention of iodine deficiency may prevent this evolution. The primary objective of the observational study diagnosis of iodine deficiency induced goiter and national medical practices (DIAGONALE) was to determine the circumstances of diagnosis of euthyroid goiter, its incidence, the patient characteristics and the management. A representative sample of GPs and ENDOs working in a private medical practice (exclusively or not) was randomly drawn from a national file without changing the physician-patient relationship. Four hundred and sixty-nine GPs and 195 ENDOs participated in the study. Goiter was diagnosed in 0.86% of patients seen by GPs and 15.7% of patients seen by ENDOs. Pregnant women were mainly and teenagers exclusively seen by ENDOs. The interview and clinical examination were an important time in the management of euthyroid goiter. TSH level was systematically assayed as well as an ultrasonography; 22.6% of GPs did not perform a scintigraphy versus 63.1% of ENDOs. Levothyroxine treatment was frequently prescribed and the objective of TSH levels was 2mU/L for GPs and 1mU/L for ENDOs. This observational study showed differences in the management of euthyroid goiter between GPs and ENDOs but also many common practices. It also highlighted a higher incidence rate of goiter in pregnant women and teenagers seen by ENDOs. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

Takotsubo cardiomyopathy (TC) is described as transient ventricular dysfunction following emotional or physical trauma. A few reports have described patients with TC in association with various circumstances of thyrotoxicosis. We report an unusual case of TC in a patient with a large retrosternal goiter and normal thyroid function. We speculate that TC was triggered by compromise of tracheal flow induced by the goiter. A 68-yr-old woman without primary heart disease presented with cardiorespiratory collapse requiring ventilatory and cardiovascular support, including placement of an intra-aortic balloon pump. She was diagnosed with a severe form of TC based on characteristic echocardiography findings and clinical course. Within less than a week, her myocardial function completely normalized. The patient was later found to have a large retrosternal goiter compressing her trachea, though her thyroid function was normal. A total thyroidectomy was eventually performed, and she made a full recovery. Subsequently, the patient was found to have a positive JAK2 mutation for a myeloproliferative disorder. Takotsubo cardiomyopathy may be regarded as the final common pathway of cardiac dysfunction triggered by various stress conditions, in this case, a large retrosternal goiter not associated with thyrotoxicosis and likely exacerbated by severe leukocytosis related to a myeloproliferative disorder.

A Survey of goiter prevalence, among population of five endemic and four non endemic regions of Ethiopia was carried out prior to the distribution of iodate d salt. urine samples were collected from 327 subjects selected by systematic random sampling from endemic and 276 taken as non endemic. The lowest mean urinary iodine excretion (UIE) value was recorded in Bure (22 micro gl/day) and the highest in Alemmaya (148 micro gl/day). The highest goiter rate ( percent TGR) was recorded in Sawla 55.6 %) and the lowest (0.6 %) in Yabello. Iodine content of drinking was in the range of 0.4 - 48.5 micro gl. Iodine content of water source was correlated positively ( r0.8399) with the mean of UIE and TGR, however, indicates that sites considered as non endemic seem to be affected by iodine deficiency. The study results urge the need for intervention in controlling Iodine Deficiency Disorders. 3 tab

Full text: Purpose: During a control of the safety measures at the Radiology Service in a local hospital in Buenos Aires, a lack of an appropriate shielding in the X-ray equipment was detected. Methods and Materials: Therefore studies were performed in the group of physicians and technicians exposed and in an age and sex matched group of non-exposed physicians and technicians. Check-ups included thyroid sonography, circulating thyroid hormones, TSH and thyroid antibodies. The exposed group included 9 females and 5 males, while the non-exposed group comprised 8 females and 5 males. Results: No thyroid abnormalities were found in the non-exposed patients. On the contrary in the exposed cohort in 11 out of 14 patients nodular goiter was diagnosed, while an additional patient presented diffuse goiter. In 5 out of the 12 patients with goiter, nodule growth or the appearance of new nodules was observed along the follow-up. Four patients presented changes in thyroid function: two had elevated basal TSH with increased titters of anti TPO antibodies in one, while another showed an abnormal TRH-TSH test. A fourth patient had low total T 4 values. Other abnormalities included: sperm abnormalities in 2 out of the 5 males, dry-eye syndrome in other two, mammary nodules in one female and a basocellular epithelioma in another one. Conclusions: accidental irradiation leads to thyroid abnormalities, such as the appearance of nodules and alterations in thyroid function. (author)

Total thyroidectomy for treatment of Graves' disease is controversial and much of the debate centers on the concern for complications. The purpose of this study was to evaluate the morbidity of total thyroidectomy for Graves' disease and determine if it is different than for patients with nontoxic nodular goiter. The rates of life threatening neck hematoma, recurrent laryngeal nerve (RLN) injury, transient hypocalcemia, and hypoparathyroidism were determined for consecutive patients with Graves' disease treated with total thyroidectomy from 1996 to 2010. Results were compared with patients who underwent total thyroidectomy for nontoxic nodular goiter during the same period, matched for the weight of the excised thyroid gland. Total thyroidectomy was performed in 111 patients with Graves' disease (group I) and 283 patients with nontoxic nodular goiter (group II). Parathyroid autotransplantation was performed in 31(28%) patients in group I and 98 (35%) patients in group II (P = NS). Comparative analysis of morbidity revealed no significant difference in neck hematoma, 0(0%) (I) versus 3(1%) (II); permanent RLN injury, 0(0%) (I) versus 2(1%) (II); and permanent hypoparathyroidism in 1(1%) (I) versus 1 (0.4%) (II) (P = NS). Transient hypocalcemia was more common in patients with Graves' disease, 80(72%) (I) versus 170 (60%) (II) (P Graves' disease; only transient hypocalcemia occurred more often than in patients with nodular goiter. Total thyroidectomy should be presented as a therapeutic option for all patients with Graves' disease. Copyright © 2011 Elsevier Inc. All rights reserved.

Increased Chromosomal and Oxidative DNA Damage in Patients with Multinodular Goiter and Their Association with Cancer

Full Text Available Thyroid nodules are a common clinical problem worldwide. Although thyroid cancer accounts for a small percentage of thyroid nodules, the majority are benign. 8-Hydroxy-2′-deoxyguanosine (8-OHdG levels are a marker of oxidative stress and play a key role in the initiation and development of a range of diseases and cancer types. This study evaluates cytokinesis-block micronucleus cytome (CBMN-cyt assay parameters and plasma 8-OHdG levels and their association with thyroid nodule size and thyroid hormones in patients with multinodular goiter. The study included 32 patients with multinodular goiter and 18 age- and sex-matched healthy controls. CBMN-cyt assay parameters in peripheral blood lymphocytes of patients with multinodular goiter and controls were evaluated, and plasma 8-OHdG levels were measured. The micronucleus (MN frequency (chromosomal DNA damage, apoptotic and necrotic cells (cytotoxicity, and plasma 8-OHdG levels (oxidative DNA damage were significantly higher among patients with multinodular goiter. Our study is the first report of increased chromosomal and oxidative DNA damage in patients with multinodular goiter, which may predict an increased risk of thyroid cancer in these patients. MN frequency and plasma 8-OHdG levels may be markers of the carcinogenic potential of multinodular goiters and could be used for early detection of different cancer types, including thyroid cancer.

Toxic multinodular goiter is a cause of nonautoimmune hyperthyroidism and is believed to differ in its nature and pathogenesis from toxic adenoma. Gain-of-function mutations of the TSH receptor gene have been identified as a cause of toxic adenoma. The pathogenesis at the molecular level of hyperfunctioning nodules in toxic multinodular goiter has yet not been reported. Six patients with a single hot nodule within a multinodular goiter and 11 patients with toxic thyroid adenoma were enrolled in our study. At histology five hyperfunctioning nodules in multinodular goiters showed the features of adenomas, and one was identified as a hyperplastic nodule. The entire exon 10 of the TSH receptor gene was directly sequenced after PCR amplification from genomic DNA obtained from surgical specimens. Functional studies of mutated receptors were performed in COS-7 cells. Five out of 6 (83%) hyperfunctioning nodules within toxic multinodular goiters harbored a TSH receptor mutation. A TSH receptor mutation was also evident in the hyperfunctioning nodule that at histology had the features of noncapsulated hyperplastic nodule. Among toxic adenomas, 8 out of 11 (72%) nodules harbored a TSH receptor mutation. All the mutations were heterozygotic and somatic. Nonfunctioning nodules, whether adenomas or hyperplastic nodules present in association with hyperfunctioning nodules in the same multinodular goiters, had no TSH receptor mutation. All the mutations identified had constitutive activity as assessed by cAMP production after expression in COS-7 cells. Hyperfunctioning thyroid nodules in multinodular goiters recognize the same pathogenetic event (TSH receptor mutation) as toxic adenoma. Other mechanisms are implicated in the growth of nonfunctioning thyroid nodules coexistent in the same gland.

Animal models of disease: feline hyperthyroidism: an animal model for toxic nodular goiter.

Science.gov (United States)

Peterson, Mark E

2014-11-01

Since first discovered just 35 years ago, the incidence of spontaneous feline hyperthyroidism has increased dramatically to the extent that it is now one of the most common disorders seen in middle-aged to senior domestic cats. Hyperthyroid cat goiters contain single or multiple autonomously (i.e. TSH-independent) functioning and growing thyroid nodules. Thus, hyperthyroidism in cats is clinically and histologically similar to toxic nodular goiter in humans. The disease in cats is mechanistically different from Graves' disease, because neither the hyperfunction nor growth of these nodules depends on extrathyroidal circulating stimulators. The basic lesion appears to be an excessive intrinsic growth capacity of some thyroid cells, but iodine deficiency, other nutritional goitrogens, or environmental disruptors may play a role in the disease pathogenesis. Clinical features of feline toxic nodular goiter include one or more palpable thyroid nodules, together with signs of hyperthyroidism (e.g. weight loss despite an increased appetite). Diagnosis of feline hyperthyroidism is confirmed by finding the increased serum concentrations of thyroxine and triiodothyronine, undetectable serum TSH concentrations, or increased thyroid uptake of radioiodine. Thyroid scintigraphy demonstrates a heterogeneous pattern of increased radionuclide uptake, most commonly into both thyroid lobes. Treatment options for toxic nodular goiter in cats are similar to that used in humans and include surgical thyroidectomy, radioiodine, and antithyroid drugs. Most authorities agree that ablative therapy with radioiodine is the treatment of choice for most cats with toxic nodular goiter, because the animals are older, and the disease will never go into remission. © 2014 Society for Endocrinology.

The response to TRH was studied in 32 patients from an endemic goiter area, 20 of them had been previously treated with iodized oil. Blood samples were taken at 0, 20, 40 and 120 minutes after de i.v. administration of 400μg of TRH, and serum levels of TSH, T3 and T4 were measured. The results obtained show that in endemic goiter area there is a modification in the hypothalamus-pituitary-thyroid feedback mechanism, with increased reserve of pituitary TSH and changes in T4 and T3 secretion. The injection of TRH gave exaggerated and delayed responses in the secretion of TSH and T3. Iodized oil used as a prophylatic method produced a disminution of pituitary TSH reserve, and of serum levels of TSH and T3, as a result of the return tonormality of the hypothalamus-pituitary-thyroid feedback mechanism.

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

1997-01-01

In order to study the etiology of endemic goiter in the north-western part of Tunisia, we examined 93 adolescents of this region. We measured urinary iodine concentrations, serum total thyroxine, total triiodothyronine, thyrotropin, thyroglobulin and antithyrogobulin antibody concentrations. The adolescents were questioned about their alimentary habits, the origin of their drinking water and the presence of known goiter(s) in their family. Among these adolescents, 49.5% of them had a goiter. Urinary iodine concentrations showed mild iodine deficiency. The serum determinations gave results within the reference ranges, without any significative differences between adolescents, with or without goiter. We found two risk factors: the age of adolescents, and the presence of a known goiter in the family. These results suggest that the actual prevention may not be adequate, or most likely that goitrogenic factors are to be looked for, especially in drinking water, since the majority of these adolescents drink no controlled water

Full Text Available Background: Iodine deficiency and its related disorder such as goiter are endemic in Lorestan province. Following initiation of iodine deficiency control program in 1989, production, distribution and consumption of iodinated salt were begun. This survey was conducted in the framework of national monitoring survey in 2001 to find out the prevalence of goiter and urinary iodine level in order to evaluate the iodine status of school- aged children in Lorestan. Materials and Methods: 1200 schoolchildren, aged 7-10 years, were selected randomly from all regions of Lorestan. The grade of goiter in 600 boys and 600 girls, was determined according to WHO classification. Urinary iodine content was estimated using the digestion method in one tenth of the schoolchildren. Findings: Total goiter rate was 7.8% 7.8% in girls and 7.7% in boys. Median urinary iodine was 17 μg/dl. Urinary iodine was above 10 μg/dl in 85.7% and less than 5 μg/dl in 1.7%. No one had urinary iodine below 2 μg/dl. Conclusion: It is concluded that the rate of goiter in Lorestan has decreased significantly since 1996 and urinary iodine levels in schoolchildren are indicative of adequate iodine intake. Therefore Lorestan province can be considered as an 'iodine deficiency free' zone.

Objective: To evaluate the treatment effects of Graves disease with large goiter treated with 131 I and the method of 131 I individualized estimated dose. Methods: Two hundred and fifty patients with Graves disease with large goiter (mean of thyroid weight 113.0 ± 39.2 g; range 90-450 g) were studied according to patient individual factors, the dose per g thyroid tissue ranging from 2. 775-5.18 MBq/g was determined, then the administered dose was calculated using the special formula. The follow-up was for 15.9 ± 9.9 (range 3-44.7) months. Results: After one dose of 131 I, 154 patients (61.6%) became euthyroid, 53 patients (21.2%) remained to be hyperthyroidism, 43 patients (17.2%) became hypothyroidism. Large goiter in 219 patients (87.6%) was normalized. Conclusions: Treatment with 131 I is an effective method for Graves disease with large goiter; According to factors affecting outcome, employing the method of individualized radioiodine therapy can improve the efficacy of 131 I treatment

There is an increased risk of fetal goiter in patients who have a history of Grave's disease and undergo propylthiouracil (PTU) treatment during pregnancy. In this report, we describe a case of a fetal goiter detected by antenatal ultrasound at the 26th week of gestation in a mother treated with PTU for Grave's disease. A 32 x 38 x 20 mm fetal goiter was detected, each lobe measured 30 x 18 x 18 mm and estimated volume was 10 cm3. Subsequently, fetal thyroid function was assessed by umbilical fetal blood sampling. Cord blood showed elevated serum TSH (40.2 mU/l) and normal concentrations of free T4 (9.5 pmol/l) and free T3 (2.6 pmol/l). There were no other ultrasonographic signs of fetal hypothyroidism. Based on the above findings, the mother's PTU dosage was reduced to 50 mg daily from a total of 150 mg and weekly ultrasonographic examinations were performed. Six weeks after the initial ultrasound, a complete regression of the fetal goiter was noted. At the 34th week of gestation, the patient was delivered due to intrauterine growth restriction and oligohydramnios and gave birth to a male, weighing 1,920 g. The newborn thyroid was not palpable and thyroid ultrasonography was normal. Cord blood TSH was normal (8.4 mU/l) and free T4 was within lower normal limit (9.03 pmol/l). Ten days later, newborn thyroid function was normal and the baby did well afterwards. In conclusion, after the evaluation of fetal thyroid status, selected cases with fetal goiter can be initially managed without intrauterine treatment. (c) 2005 S. Karger AG, Basel

Activating thyrotropin (TSH) receptor mutations have been found in toxic adenomas and in hot nodules contained in toxic multinodular goiter. The typical feature of multinodular goiter is the heterogeneity in morphology and function of different follicles within the same enlarged gland. In this report we describe a patient with a huge multinodular goiter, normal free triiodothyronine (FT3) and free thyroxine (FT4) serum values, and subnormal TSH serum concentration. Thyroid scintiscan showed two hot areas corresponding to the basal and apical nodules of the left lobe. The right lobe was poorly visualized by the radioisotope. The patient underwent thyroidectomy, and histological examination of the tissue was performed. Genomic DNA was extracted from the tissue specimen and direct sequencing of the TSH receptor and Gs alpha genes was done. At histology, one hyperfunctioning nodule had the typical microscopic structure of thyroid adenomas, and the other contained multiple macrofollicular areas not confined by a capsule. In spite of this histological difference, both hyperfunctioning nodules harbored a mutation of the thyrotropin receptor (TSHr) gene: an isoleucine instead of a threonine in position 632 (T632I) in the first nodule and a methionine instead of an isoleucine in position 486 (I486M) in the second nodule. In conclusion, our findings show for the first time that gain-of-function TSHr mutations are not only present in hyperfunctioning thyroid nodules with the histological features of the true thyroid adenomas, but also in hyperfunctioning hyperplastic nodules contained in the same multinodular goiter.

2004-01-01

Background: To eliminate Iodine Deficiency Disorders, (IDD) universal salt iodization is the widely practiced intervention. District Swat (a hilly area of NWFP, highly endemic for IDDs is selected as a first model district of the province for salt iodization program. Objectives: To find out the proportion of the families using iodized salt, iodine contents of the salts used by the families, urinary iodine levels in school children and the effect on goiter prevalence in Swat selected as a model district in 1998. Subject and Methods: The study was conducted in 960 children of both sexes, age 8-10 years in primary schools of district Swat in the year 2000. A replicate model used for base line study in 1998 was adopted. The students were clinically examined for goiter using palpation method. 960 edible salt samples for its iodine content and 240 urine samples for iodine level were analysed. Results: The overall goiter prevalence was found to be 52 and 45% in boys and girls respectively. 23% salt samples were found un-iodized, while in 25.6% the iodine content was less than 7ppm. The results revealed 18% decrease in total goiter rate and 35% increase in the use of iodized salt from the base line survey conducted in 1998, in school children of district Swat. Conclusions: The study revealed that since the area of Swat is still highly endemic for Iodine Deficiency Disorders, sustained efforts are required to ensure 100% salt iodization. (author)

Non-surgical approach to the benign nodular goiter: new opportunities by recombinant human TSH-stimulated (131)I-therapy

DEFF Research Database (Denmark)

Bonnema, Steen Joop; Fast, Søren; Hegedüs, Laszlo

2011-01-01

The optimal treatment strategy in a goiter patient depends-among other factors-on goiter size, the degree of cosmetic or compressive symptoms, the age of the patient, the impact on the upper airways, the wish to maintain normal thyroid function, the ability of the thyroid gland to take up (131)I......, and the possibility of thyroid malignancy. When treatment is warranted in a patient with benign goiter, the choice usually stands between surgery and (131)I-therapy. Focal destructive treatment, by ethanol sclerotherapy or interstitial laser photocoagulation, may be considered in patients with a solitary benign...... nodule. If thyroid hyperfunction due to nodular autonomy is the dominant problem, life-long anti-thyroid drug treatment may be relevant in elderly individuals. With the advent of recombinant human TSH (rhTSH) stimulation the goiter reduction following (131)I-therapy is significantly enhanced...

2016-01-01

Full Text Available Background: Dyshormonogenetic goiter is one of the most common causes of hypothyroidism in children and adolescents in iodine nonendemic areas. The exact genotype-phenotypic correlations (GPCs and risk categorization of hypothyroid phenotypes of dyshormonogenetic mutations are largely speculative. The genetic studies in pediatric dyshormonogenesis are very sparse from Indian sub-continent. In this context, we analyzed the implications of TPO, NIS, and DUOX2 gene mutations in hypothyroid children with dyshormonogenetic hypothyroidism (DH from South India. Materials and Methods: This is interdisciplinary prospective study, we employed eight sets of primers and screened for 142 known single nucleotide polymorphisms in TPO, NIS, and DUOX2 genes. The subjects were children and adolescents with hypothyroidism due to dyshormonogenetic goiter. Congenital hypothyroidism, iodine deficiency, and Hashimoto's thyroiditis cases were excluded. Results: We detected nine mutations in 8/22 (36% children. All the mutations were observed in the intronic regions of NIS gene and none in TPO or DUOX2 genes. Except for bi-allelic, synonymous polymorphism of TPO gene in child number 14, all other mutations were heterozygous in nature. GPCs show that our mutations significantly expressed the phenotypic traits such as overt hypothyroidism, goiter, and existence of family history. Other phenotypic characters such as sex predilection, the age of onset and transitory nature of hypothyroidism were not significantly affected by these mutations. Conclusion: NIS gene mutations alone appears to be most prevalent mutations in DH among South Indian children and these mutations significantly influenced phenotypic expressions such as severity of hypothyroidism, goiter rates, and familial clustering.

Watanabe, Tomas; Degrossi, O.J.; Zaninovich, A.A.; Altschuler, Noe; Degrossi, E.B.

1986-01-01

T3 kinetics were carried out in 32 children (11-15 years old) of a mild endemic goiter area. The incidence of goiter of the whole school population was 19% (Ia or Ib degree of the WHO). The mean urinary iodine was 84 μ g/d+-3. Six months before this investigation, 10 of the children received 2 ml of ethiodol by mouth and the other 22 (control group-CG) a placebo. The kinetics studies were carried out using less than 0,5 μ Ci of I-125 per Kg b.w. and the single injection method, non compartimental analysis. The CG shows, distribution volumen (V) 20.1+-0.6; serum T3 (sT3) 1.55 ng/ml+-0.03; plasma T3 T1/2 21.6+-0.6 and production rate (PR) 27.4μ g/d+-1.2. The treated group (TG): V, 17.3+-0.6; sT3 1.48 ng/ml+-0.09; T1/2 17.6+-0.6 and PR 25.9μ g/d+-1.4. The TG, after 6 months of ethiodol administration, showed a decrease of the distribution volume and a slight reduction in serum T3 values. As a consequence a significant diminution on the T3 extrathyroidal pool and an increase on the T3 plasma clearance (0.68 l/h+-0.01 in CG versus 0.73+-0.3 in TG) were observed. The production ratewas similar in both groups. These results indicate that the administration of ethiodol to children of a not severe endemic goiter area, produces moderate changes in the different parameters of T3 peripheral metabolism, which compensate each other and lead to similar final values on T3-PR, that were previously normal in these cases. This mechanism reflects the role of thyroid homeostasis in maintaining euthyroidism in these children of an endemic goiter area with decreased iodine supply. (Author) [es

Full Text Available Objectives: To find out the magnitude of iron deficiency anemia in the age group of 6–12 years and investigate the role of iron deficiency as a possible contributor to endemic goiter in school children in Ambala. Materials and Methods: The present study was conducted as a subset of a cross-sectional study among 2700 children from 6 to 12 years of age to find out the prevalence of goiter. All the subjects who were found to be suffering from goiter in the cross-sectional study were enrolled in the case–control study as cases and were compared with age- and sex-matched controls (children without goiter from the same cohort. The study was conducted from February 2011 to January 2012. Results: Out of total, goiter was observed in 12.6% of the subjects. Urinary iodine excretion was found to be <100 μg/L in 57 (10.5% children. Mean hemoglobin (Hb level of the study population was 11.9 g/dL. It was noted that 71% of the goitrous children had anemia (Hb <12 g/dL as compared to 63.7% of the control group. Serum ferritin (SF was <15 ng/mL in 70% of the children. The mean ± standard deviation of SF in the goitrous and nongoitrous children was 19.65 ± 32.51 μg/L and 27.55 ± 21.07 μg/L, respectively (P = 0.012. Conclusion: The findings in the study suggest that iron deficiency anemia in children is contributing toward the persistence of goiter in the postiodization phase.

Full Text Available Background and objectivesIodine deficiency was a public health problem in Iran before the start of iodine supplementation program in 1989. This study has been conducted in the framework of the national monitoring survey in 2001 to find the prevalence of goiter and urinary iodine levels in order to evaluate the effect of national supplementation program on the iodine status of school-aged children in the city of Qom. MethodsIn a descriptive, cross-sectional study, 1200 schoolchildren, aged 7-10 years, were selected randomly from all regions of Qom, and the grade of goiter was determined in 600 boys and 600 girls according to WHO classification. Urinary iodine content was estimated using the digestion method in one tenth of the schoolchildren.ResultsGoiter was observed in 26% of children (24.3% of girls and 27.7% of boys. The average urinary iodine level was 15.2 µg/dl. Urinary iodine levels higher than 10 μg/dl was measured in 71.7% and less than 5 µg/dl in 8.1% of children. Urinary iodine levels less than 2 μg/dl has not been observed in any of the cases. No significant difference was observed in prevalence of goiter and the urinary iodine level between males and females, and students in living in urban or rural areas.ConclusionComparison of these results with those of the year 1996 shows that prevalence of goiter has significantly decreased in these students. Also, it shows that in the city of Qom, the urinary iodine levels of schoolchildren fall in the standard range determined by WHO. This indicates that the iodine intake is adequate in the province of Qom. Therefore, this province can be considered as an “iodine deficiency-free” zone.Keywords: Goiter; Goiter Endemic; Iodine.

In order to evaluate the efficacy of, and the risk associated with, the definite treatment of euthyroid goiter with autonomy, the data of 88 patients treated between 1982 and 1986 (50 by subtotal thyroidectomy; 38 by 131 I-treatment, mean radiation dose 200 Gy without protection by thyroxine) were analyzed in a retrospective study. The following criteria were used before and after treatment: the results of scintigraphy under suppression qualitatively (in focal autonomy) and quantitatively (global thyroid uptake) (TcU s ), the means of FT 4 I, FT 3 I and ΔTSH after TRH, the improvement of mechanical signs and symptoms and the decrease of thyroid volume. Measured by TcU s and ΔTSH, autonomy could be removed completely in 85-90% of all patients. Surgery was slightly more successful (100%) compared to treatment by 131 I (75-80%). This was also true for removal of mechanical symptoms and reduction of the goiter. The incidence of manifest hypothyroidism was greater after surgery (16%) than after 131 I treatment (3%). At a higher grade of autonomy (TcU s > 3.2%) surgery was more effective (95-100%) than treatment with 131 I (60-70%) but at a higher risk of hypothyroidism (24 vs 0%). It is imperative to improve the methods of estimating the amount of 131 I to be administered in euthyroid goiter with autonomy. Selection of patients with autonomy in euthyroid goiter for definite treatment is difficult, since until now their risk to become hyperthyroid cannot be predicted properly. (orig.) [de

The results of scintigphic and cytological investigations in 548 patients with goiter are presented: In 402 goiters 470 nodes were detected, 385 of which were scintigraphically 'cold'. 276 solitary nodules were found, 109 in cases of multinodular goiter. Solitary nodules were preferentially located in the right lobe. The cytological diagnosis was confirmed histologically in 88 cases. Out of 24 malignant tumors, 21 were diagnosed correctly by means of cytology. The positive smears and the histological findings were in agreement in 14 of 15 cases. The accuracy of cytological diagnosis in the detection of thyroid malignancies was 87.5%. 12.5% of the smears were false negatives, 1.6% false positives and 10.9% false suspicious. The relative high percentage of false suspicious smears is caused by difficulties in cytologic differentiation of thyroid lesions due to microfollicular structures which are usually only classified as 'folicular neoplasia'. This cytologic term necessitates an obligatory histologic examination since cytology does not allow to differentiate between follicular adenomas and carcinomas. 5.5% of the histologically ascertained cold nodules were malignant, in 19% of the cases with cold nodes thyroid punction revealed cystic lesions.

The aim of this study was to analyze and describe the epidemiological characteristics and trends of thyroid cancer in the province of Sassari (Sardinia, Italy), an area with epidemic thyroid goiter, in the period 1992-2010. Data were obtained from the local tumor registry which makes part of a wider registry web, coordinated today by the Italian Association for Tumor Registries. An increasing trend in the incidence of thyroid cancer in the province of Sassari was evidenced. This trend seems to follow the general worldwide trend and does not seem to be related to the high incidence of thyroid goiter in the area. The frequencies of the different histological subtypes were similar to those reported in numerous national and international reports. Women are affected earlier than men and, therefore, suffer greater professional, economic, and social impacts. Overall mortality is low and a relative 5-year survival is excellent, especially in comparison to other malignancies

To investigate the level of expression and the clinical significance of IL-2 (interleukin-2), IL-6 (interleukin-6) and TGF-β (transforming growth factor-β) in elderly patients with goiter and hyperthyroidism. Gender, age, course of disease, BMI (Body Mass Index), serum FT3 (Free triiodothyronine-3), FT4 (Free triiodothyronine-4), TT3 (Total triiodothyronine-3), TT4 (Total triiodothyronine-4), TSH (Thyroid Stimulating Hormone) and clinical manifestations on admission and other general clinical data and laboratory examination results were collected and statistically analyzed as case group in 128 elderly patients with goiter and hyperthyroidism. Additional 128 over 60-year-old patients with hyperthyroidism were selected as control group. The thyroid tissue of these patients and the control group were examined by fine needle aspiration biopsy. The expressions of IL-2, IL-6, TGF-β of the thyroid tissue in all patients were detected by immunohistochemistry, qRT-PCR (Real-time Quantitative Polymerase Chain Reaction) and Western blot method respectively, and the statistical analysis was carried out. p hyperthyroidism and thyroid enlargement (p hyperthyroidism, and symptoms of exophthalmos, the level of expression of IL-6 was significantly higher than that of patients without exophthalmos (p hyperthyroidism and symptoms of exophthalmos, and the patients with goiter, hyperthyroidism without symptoms of exophthalmos, IL-2 and TGF-β expression level were not different (p > 0.05). The expression levels of IL-2, IL-6, and TGF-β were significantly increased in the patients with senile goiter and hyperthyroidism, but in the senile patients with goiter, hyperthyroidism and exophthalmos symptoms, IL-6 levels were significantly higher than those without exophthalmos. The use of IL-2, IL-6, and TGF-β is of great significance in the diagnosis of goiter with hyperthyroidism, especially for elderly patients with atypical clinical symptoms of hyperthyroidism.

Full Text Available Objective: to study the effects of the diffuse non-toxic goiter treatment on the functional state of the digestive system in children. Materials and methods. The screening survey was based on lunior comprehensive schools (695 children aged 5–11 years: questioning of families, anthropometry and examination of children, detection of ioduria, palpation of the thyroid gland. In-depth examination of children with goiter (n = 88: ultrasonography of the thyroid gland and the digestive system, determination of levels of thyroid stimulating hormone, free thyroxine, serotonin, melatonin, vasoactive intestinal peptide. Results. The high incidence of non-toxic diffuse goiter (25.8 %, associated with a reduction in functional activity of the thyroid gland to the minimum thyroid dysfunction (42.0 % and subclinical hypothyroidism (10.2 %, was detected in school-aged children. The presence of goiter leads to a static increase of the chances for functional gastrointestinal disorders developing (odds ratio 2.33, p = 0.000, mainly due to the hypokinetic conditions. The administration of potassium iodide preparations leads to the decreasing in goiter rate in high compliance up to the 27.3 % and to the normalization of the functional state of the pituitary-thyroid system (thyroid stimulating hormone — 1.66 mIU/L, that is associated with increased level of serotonin (6.14 ng/ml and vasoactive intestinal peptide (117.86 ng/ml and decreased melatonin concentration (2.5 pmol/l. In children who consistently for six months received preparations of potassium iodide, along with the normalization of thyroid status we noted the decrease of the frequency of complaints from the digestive system. Conclusions. The treatment of diffuse nontoxic goiter by potassium iodide preparations allows to achieve reduction of thyroid size and to normalize functional activity of thyroid-pituitary system. Increase in the functional activity of the pituitary-thyroid system helps reduce the

Rarely the patient's metabolism is pondered when the quantity of radioactive material administrated to the patient is calculated. Nowadays, realizing till 150 mCi/g activities treatments are not indicated to toxic goiter radiotherapy. This paper objectives to establish a group of 13I -treatment options optimization for owner toxic goiter patients to maximize benefits and minimize radiological detriments. Methodology consisted of effective and absorbed whole-body and the other organs doses evaluations. And to observe the relation between these values and the thyroid mass and captivation percentage. The results, in spite of characteristic variations of each patient, showed such a homogeneity. This phenomenon happens because of explicit dependency on the real activity administrated to the patient. Used protocols for the toxic goiter treatment optimization avoiding waste of radioisotopes.

Full Text Available Introduction: Iodine deficiency disorders (IDD create major public health problems in India, including Gujarat. Panchmahal district is known for endemic iodine deficiency. The present study was conducted to (1 estimate the prevalence of goiter in primary school children, (2 determine median urinary iodine concentration, (3 assess the level of iodine in salt samples at the household and retail shop level, and (4 profile of salt sold at retail shops in Panchmahal district, Gujarat. Methods: A total of 70 students including five boys and five girls from 1st to 7th standard who were present on the day of the first visit were selected randomly for goiter examination from each village. Urine samples were collected from one boy and one girl from each standard in each cluster. From the community, at least 28 students, including two boys and two girls from each standard in the same age group, were examined, and salt samples were tested from their households. A total of 2100 students were examined in schools and 928 students were examined in the selected villages. From each village, one retail shop was visited, and salts purchased from those shops were immediately tested for iodine with spot kits.Results: Among young primary school children, goiter prevalence was 23.35% (grade 1—18.35%, grade 2—5.0%. As the ages increase, goiter prevalence also increases except for 9-year-olds. The median urinary iodine excretion level was 110 µg/L. An iodine level >15 ppm was found in 78.3% of the salt samples tested at household level. Conclusion: The present study showed considerable goiter prevalence in primary school children in Panchmahal district of Gujarat and an inadequate iodine content of salt at the household level.

Outbred stocks of rats have been used extensively in biomedical, pharmaceutical and/or toxicological studies as a model of genetically heterogeneous human populations. One of such stocks is the Wistar Hannover GALAS rat. However, the colony of Wistar Hannover GALAS rat has been suspected of keeping a problematic mutation that manifests two distinct spontaneous abnormalities, goiter and dwarfism, which often confuses study results. We have successfully identified the responsible mutation, a guanine to thymine transversion at the acceptor site (3' end) of intron 6 in the thyroglobulin (Tg) gene (Tgc.749-1G>T), that induces a complete missing of exon 7 from the whole Tg transcript by mating experiments and subsequent molecular analyses. The following observations confirmed that Tgc.749-1G>T/Tgc.749-1G>T homozygotes manifested both dwarfism and goiter, while Tgc.749-1G>T/+ heterozygotes had only a goiter with normal appearance, suggesting that the mutant phenotypes inherit as an autosomal semi-dominant trait. The mutant phenotypes, goiter and dwarfism, mimicked those caused by typical endocrine disrupters attacking the thyroid. Hence a simple and reliable diagnostic methodology has been developed for genomic DNA-based genotyping of animals. The diagnostic methodology reported here would allow users of Wistar Hannover GALAS rats to evaluate their study results precisely by carefully interpreting the data obtained from Tgc.749-1G>T/+ heterozygotes having externally undetectable thyroidal lesions.

Benign thyroid nodules are common in iodine deficient countries like Germany. Current standard treatment of iodine deficient goiter is oral iodine and or levothyroxine but solid evidence on which to base dosage and duration of treatment is still missing. Recent studies have addressed a new pathogenic concept of a true neoplasia in thyroid nodules. Based on the pathogenesis, the effectiveness of thyroid hormone suppressive therapy in reducing volume of benign thyroid nodules is a matter of controversy since many years. It is necessary to clarify this therapeutic effect, because its use needs to be carefully weight against its potential deleterious effects in the skeletal and cardiovascular system e.g. in elderly patients. Iodine deficient goiter is the best option for medical treatment. Benign thyroid nodules displayed a slow but continous growth during long-term follow up. Treatment with levothyroxine and/or iodide did not significantly influence growth of nodules. From a therapeutic point of view, prevention of thyroid nodules in iodine deficient countries needs an early and different strategy than the therapy of existing nodules. (orig.)

The increase of certain operations in the wake of the introduction of the German Diagnosis-Related Groups (G-DRG) system rekindled debate on the risk-benefit profile of what is widely being perceived as a too high number of thyroidectomies for benign goiter in Germany. The numbers of thyroidectomy for benign goiter from 2005-2011 were obtained from the Federal Bureau of Statistics ("Statistisches Bundesamt"). For the purpose of the study, the following operation and procedure key (OPS) codes were selected: hemithyroidectomy (OPS code 5-061); partial thyroid resection (OPS code 5-062); total thyroidectomy (OPS code 5-063); and thyroid surgeries via sternotomy (OPS code 5-064). The rates of permanent hypoparathyroidism and vocal cord palsy were calculated based on two prospective multicenter evaluation studies conducted in 1998-2001 (PETS 1) and 2010-2013 (PETS 2) in Germany. Between 2005 and 2011, the number of thyroidectomies for benign thyroid goiter decreased by 8 %, and the age-standardized surgery rate decreased by 6 % in men (2005: 599 per 1 million; 2011: 565 per 1 million) and 11 % in women (2005: 1641 per 1 million; 2011: 1463 per 1 million). At the same time, the rates of partial and subtotal thyroidectomy decreased by 59 % in men and 64 % in women, whereas the rates of hemithyroidectomy and total thyroidectomy increased by 65 % (113 %) in men and 42 % (97 %) in women. Despite a greater proportion of thyroidectomies over time, the approximated rates for postoperative hypoparathyroidism were reduced from 2.98 to 0.83 % and for postoperative vocal cord palsy from 1.06 to 0.86 %. Irrespective of that decline, either complication was more frequent after total than after subtotal thyroidectomy. The total number of thyroid surgeries due to benign goiter has decreased substantially in Germany from 2005 through 2011. Despite changes in the resectional strategy with an increase in the total number thyroidectomies and a decrease of subtotal

Full Text Available The article highlights the evaluation results of the IQ indices demonstrated by the school students, who reside in the regions with different degrees of the iodine deficiency severity and iodine provided regions. The authors performed the comparative analysis of the IQ indices among children with clinically euthyroid diffusive goiter and among children with normal sizes of the thyroid gland. The research included 260 children aged from 8 to 10 from 13 regions of the Russian Federation: 130 patients with the goiter diagnosed subject to the data of the ultrasound investigation and 130 children, who have normal sizes of the thyroid gland (reference group. The comparison groups were homogenous according to the education conditions (as only children from the city comprehensive schools took part in the research. For the evaluation of the intellectual development, authors used R. Kettell's intellect test free from the cultural impact (Сulture-Fair Intelligence Test, CFIT — CF 2А form. Despite the fact that the average IQ indices in the group of children with goiter were slightly lower than among children with normal sizes of the thyroid gland, the researchers failed to identify statistically significant differences between the average IQ indices among children in the compared groups (р > 0,05. Both in the group of children with goiter and in the reference group, the average IQ indices fell within «the low normal» (80–89 points.Key words: iodine, hypothyroidism, IQ intellect index, children.

Surgical treatment is the first option for patients with obstructive multinodular goiter. The extent of the resection and the use of postoperative hormonal therapy are, on the other hand, still under debate. To analyze the results of surgical treatment in 101 patient with multinodular goiter seen from 1980 to 1995. The clinical/pathologic charts of all patients were reviewed with emphasis to the clinical diagnosis, extent of resection, final histology, type and number of complications, and long-term follow-up. The mean follow-up was three years (range 0.5-12). Ten males and 91 females with a mean age of 46 years were included. Surgery was recommended for a nodule suspicious of malignancy in 60 patients, for airway compression in 33, and for cosmetic reasons in eight. Unilateral lobectomy was performed in 30, bilateral subtotal thyroidectomy in 55 and total thyroidectomy in 16. Postoperative hormone therapy was administrated to 83 patients. Surgical complications occurred in six patients. Four developed permanent hypoparathyroidism and two vocal cord paralysis. There was no operative mortality. A final diagnosis of multinodular goiter was established in 89 whereas 12 had cancer. There were three asymptomatic recurrences in the group with benign lesions (they had undergone unilateral lobectomy followed by hormonal therapy). Bilateral subtotal thyroidectomy was the best treatment for multinodular goiter in our series. This procedure had few complications and there was no recurrence of the disease.

Full Text Available Introduction: Clinical evaluation of iodine deficiency disorders (IDDs is often accomplished by assessment of urinary iodine excretion (UIE in random samples; however, the utilization of 24 hour urine samples is a more reliable biomarker of nutritional iodine status. This study was designed to evaluate total goiter prevalence (TGP and iodine/creatinine ratio among school-aged children in Urmia County. Methods: Schoolchildren (n=500 were recruited by cluster sampling from different educational areas in Urmia County. Goiter prevalence was assessed by thyroid palpation, UIE was determined by Sandell-Koltoff reaction, and Urinary creatinine was measured by the Jaffe-method. Results: In general, TGP was 12.2%. Among these, there were 48 individuals (9.6% with grade I goiter and 13 subjects (2.6% with grade II goiter. Mean urinary creatinine, median UIE and median I/Cr ratio were respectively 1.36±0.76 mg/dL, 14.3µg/dL, and 11.5µg/mg. Prevalence of iodine deficiency according to UIE criteria was 22.8% and that of I/Cr ratio was 41.2%. There was a correlation between age and UIE (P=001; r=0.163. UIE and urinary creatinine were correlated as well (P<0.003; r= 0.133. A correlation was also detected between I/Cr ratios and UIE (P=0.003; r=0.133 whilst a negative association was seen between age and I/Cr ratios (P=0.001; and r=–0.263. Conclusion: This investigation reconfirms that there is slight-to-mild iodine deficiency in Urmia County. The utilization of I/Cr ratio in conjugation with UIE and palpation may provide a better assessment in investigating nutritional iodine status.

Thyroid nodules are very common and less than 10% of them are malignant. They pose a serious diagnostic and therapeutic problem with respect to their benign or malignant nature. The study of some clinical and paraclinical factors for presumed malignancy makes it possible to codify appropriate therapeutic strategy. The aim of this study was to investigate predictors of malignancy in nodular goiters and to compare our results with those reported in the literature. This retrospective study consisted of 500 cases of nodular goiter operated in the Department of Otorhinolaryngology (ear, nose and throat or ENT) and Head and Neck Surgery at Avicenne military hospital in Marrakech between 2006 and 2012. The percentage of cancers was 6,8%. The average age of our patients was 46 years, with a sex-ratio of 5 (F/H). The hard nature of the nodule was present in 94,4% of the cases of cancer by palpation; irregular boundaries were present in 64.70% of the cases of cancer. Three nodules were fixed and malignant. Cervical lymphadenopathy were observed in 8 patients, 7 of which had cancer. Ultrasound examination showed hypoechoic appearance in 61,8% of the malignant nodules, with smooth-edges in 88,24% of the cases. Intranodular vascularization was found in 35,3% of the cases of cancers, with microcalcifications in 55,9% of the cases. Perinodular hypoechoic halo was incomplete in 73,5% of the cases of cancer. Our patients were euthyroid in 84,6% of the cases. Predictors of malignancy in nodular goiters were present in our first clinical study: patients over the age of 60 years, hard consistency of nodule, fixity, irregular and poorly defined character by palpation, as well as presence of cervical adenopathy on examination; and echographic features: hypoechoic character, smooth-edges, presence of microcalcifications and visualization of intranodular vascularization with or without peri-nodular vascularization. Although some of these factors are highly predictive of malignancy, only

Toxic multinodular goiter, a heterogeneous disease producing hyperthyroidism, is frequently found in iodine-deficient areas. The pathogenesis of this common clinical entity is still unclear. The aim of the present study was to search for activating TSH receptor (TSHr) or Gs alpha mutations in areas of toxic or functionally autonomous multinodular goiters that appeared hyperfunctioning at thyroid scintiscan but did not clearly correspond to definite nodules at physical or ultrasonographic examination. Surgical tissue specimens from nine patients were carefully dissected, matching thyroid scintiscan and thyroid ultrasonography, to isolate hyperfunctioning and nonfunctioning areas even if they did not correspond to well-defined nodules. TSHr and Gs alpha mutations were searched for by direct sequencing after PCR amplification of genomic DNA. Only 2 adenomas were identified at microscopic examination, whereas the remaining 18 hyperfunctioning areas corresponded to hyperplastic nodules containing multiple aggregates of micromacrofollicules not surrounded by a capsule. Activating TSHr mutations were detected in 14 of these 20 hyperfunctioning areas, whereas no mutation was identified in nonfunctioning nodules or areas contained in the same gland. No Gs alpha mutation was found. In conclusion, activating TSHr mutations are present in the majority of nonadenomatous hyperfunctioning nodules scattered throughout the gland in patients with toxic or functionally autonomous multinodular goiter.

Full text: Background: rh TSH increases the thyroid 131 I uptake (RAIU) and may have a role in the context of 131 I therapy of goiter. No placebo-controlled trial has yet been performed. Methods: In a double-blinded trial, 57 patients with nodular nontoxic goiter (51 F, 6 M) were randomized to receive either 0.3 mg rh TSH (n=28) or placebo (n=29) 24 h before 131 I. The thyroid dose was calculated based on thyroid size (measured by ultrasound) and RAUI at 24 h and 96 h. Thyroid size and function and patient satisfaction were monitored for 12 months. Results: At baseline the median goiter volume was 51 ml (range: 20-99 ml) in the placebo group and 59 ml (25-92 ml) in the rh TSH group (p=0.75). Three months after 131 I the goiter size was reduced to 38 ml (15-78 ml) and 43 ml (20-75 ml) in the two groups, respectively (p=0.001 within groups, p=0.96 between groups). At 12 months, the corresponding figures were 27 ml (15-82 ml) and 20 ml (6-59 ml); p=0.001 within groups compared with baseline, p=0.12 between groups. The relative goiter reduction at this time was 46 ± 22% in the placebo group, and 61 ± 15% in the rh TSH group (p=0.004). In addition to the influence of rh TSH, the magnitude of the goiter reduction correlated inversely with the initial goiter volume (p=0.019), whereas no significant correlation was found with the RAIU during therapy or with the absorbed thyroid dose. Discomfort during 131 I was reported by 10 patients in the placebo group and by 15 patients in the rh TSH group (p=0.12). Permanent hypothyroidism developed in 12% in the placebo group and in 52% in the rh TSH group (p=0.005). Patient satisfaction was generally very high without any major within group difference. Conclusion: In the first placebo-controlled double-blinded trial, we found that rh TSH prior to 131 I -therapy significantly improves thyroid size reduction by 33%, with a four-fold higher rate of hypothyroidism. These effects are, at least partially, mediated through other

Conclusions. Excess of copper unbound to metallothionein in goitrous-changed tissue and high level of inorganic iodine could be the reason for elevated DNA fragmentation and increased lysosomal membrane permeability and activation of antioxidant defense. The main criterions of goiter formation were represented by low level of organificated iodine and high level of DNA damage in thyroid gland.

Full Text Available Background: Iodine deficiency disorder (IDD creates major public health problems in India, including Gujarat. The Bharuch district is a known iodine deficiency endemic area. This study was conducted to estimate the prevalence of goiter in primary school children; to determine the median urinary iodine concentration; to assess the level of iodine in salt samples at the household and retail shop levels; and to study the profile of salt sold at retail shops. Methods: This study was carried out by using the 30-cluster survey method in the primary schools of the rural areas in Bharuch district. A total of 70 students, including five boys and five girls from the first to seventh classes, who were present in class on the day of the visit were selected randomly for goiter examination from each village. Urine samples were collected from one boy and one girl from each class in each cluster. From each community, a maximum of two boys and two girls from each standard in the same age group were examined and also salt samples were tested from their households. From each village, one retail shop was visited and the salt purchased from those shops was immediately tested for iodine with spot kits. Results: We found a goiter prevalence of 23.2% (grade 1 - 17.4% and grade 2 - 5.8%. As the age increased, the goiter prevalence decreased except in nine-year-olds. The median urinary iodine excretion level was 110 μg/L. An Iodine level > 15 ppm was found in 93% of the salt samples tested at the household level. Conclusion: The present study showed moderate goiter prevalence in primary school children in the Bharuch district of Gujarat and an inadequate iodine content of salt at some household levels.

Full text of publication follows. Objective: the aim of this study was to analyze success of radioiodine therapy in patients with toxic multi-nodular goiter (TMG). Methods: The group of 43 patients (36 females / 7 males, aged 47 ± 11 yrs, range 27 - 75 yrs) with TMG were treated with radioiodine. 28 patients were treated with one dose, 12 patients with two doses and 7 patients with three and more doses according to Marinelli's formula. The administered activity of J -131 was established basing on radioiodine uptake and goiter size ( median 555 MBq, range: 370 - 1100 MBq). Patients were evaluated by clinical and thyroid examination of TSH, FT4, FT3 after 1 - 3 months. Thyroid scintigraphy was performed 3 months after radioiodine therapy. Prior to treatment with J -131 all patients were treated with antithyroid medications, who were suspended 4 - 7 days and restarted one week after J - 131 therapy. Results: in 76,8% (33/43) patients there was control of disease after the first J -131 dose and in 95,2% (40/43) patients after the second and more doses. At 20 years of follow up, there were 84,4% (36/43) patients euthyroid, 13,9% (6/43) patients hypothyroid and 4,6% (2/43) patients hyperthyroid. Reduction of gland weight were in 74,4% (32/43) patients. During 20 years of follow up no adverse side effects were observed after J - 131 therapy. Conclusion: radioiodine therapy is the right choice of treatment for toxic multi-nodular goiter and single dose of J -131 is successful in most of the cases. A single higher radioiodine dose diminishes the need for additional J -131 therapy, without increasing of developing hypothyroidism. (authors)

Aim: Large-scale survey to focus on management of multinodular goiter and to compare the approaches of practitioners in primary care and thyroid specialists in Germany. Methods: Replies to a questionnaire were received from 2,191 practitioners and 297 thyroid specialists between June 1 and September 30, 2005. The hypothetical cases and their modifications described multinodular goiters of different sizes with and without toxic nodules. Results: In the workup, TSH determination and thyroid sonography were found to be standard procedures. Scintigraphy was selected by 80.2% of practitioners and 92.9% of specialists (p <0.001), in preference to fine needle aspiration cytology (17.9% of practitioners and 34.5% of the specialists, p <0.001). Only 6.1% of practitioners and 24.4% of specialists (p <0.001) advocated calcitonin screening. Euthyroid multinodular goiter (50-80 ml) was treated medically by 67.1% of practitioners and 65.6% of specialists, the combination of levothyroxine with iodine being clearly preferred (54.5% of practitioners, 52.3% of specialists). For toxic nodular goiter the preference for radioiodine therapy was significantly higher (p <0.001) among specialists (67.7%) than among practitioners (47.5%). Referral to surgery was recommended for cold nodules with negative cytology by 64.9% of practitioners and 73.5% of specialists (p = 0.004). Conclusions: Treatment and diagnostic procedures are used to nearly the same extent in primary care and specialist institutions, but the opinions diverge over the issues of calcitonin screening and referral for radioiodine therapy.

Methods: Replies to a questionnaire were received from 2,191 practitioners and 297 thyroid specialists between June 1 and September 30, 2005. The hypothetical cases and their modifications described multinodular goiters of different sizes with and without toxic nodules. Results: In the workup, TSH determination and thyroid sonography were found to be standard procedures. Scintigraphy was selected by 80.2% of practitioners and 92.9% of specialists (p <0.001), in preference to fine needle aspiration cytology (17.9% of practitioners and 34.5% of the specialists, p <0.001). Only 6.1% of practitioners and 24.4% of specialists (p <0.001) advocated calcitonin screening. Euthyroid multinodular goiter (50-80 ml) was treated medically by 67.1% of practitioners and 65.6% of specialists, the combination of levothyroxine with iodine being clearly preferred (54.5% of practitioners, 52.3% of specialists). For toxic nodular goiter the preference for radioiodine therapy was significantly higher (p <0.001) among specialists (67.7%) than among practitioners (47.5%). Referral to surgery was recommended for cold nodules with negative cytology by 64.9% of practitioners and 73.5% of specialists (p 0.004). Conclusions: Treatment and diagnostic procedures are used to nearly the same extent in primary care and specialist institutions, but the opinions diverge over the issues of calcitonin screening and referral for radioiodine therapy.

Aim: Gain-of-function mutations of the thyrotropin receptor (TSHR) gene have been invoked as one of the major causes of toxic thyroid adenomas. This study evaluates F-18-FDG-PET in these patients. Methods: Twenty patients with focal autonomous nodules and ten with disseminated autonomy were investigated the day before radioiodine therapy. Twenty patients with cancer of the head or neck and normal thyroid function served as controls. Results: F-18-FDG-Uptake was higher in patients than in controls. Focal autonomous nodules were associated with focally enhanced glucose metabolism. Disseminated autonomous goiters showed various patterns of focal or global hypermetabolism. Conclusion: Autonomous thyroid tissue caused by constitutive mutations of the TSH receptor is characterised by simultaneous increases in glucose and iodine metabolism which are correlated. (orig.)

The treatment of hyperthyroidism is aimed at improving health-related quality of life (HRQoL) and reducing morbidity and mortality. However, few studies have used validated questionnaires to assess HRQoL prospectively in such patients. The purpose of this study was to assess the impact of hyperthyroidism and its treatment on HRQoL using validated disease-specific and generic questionnaires. This prospective cohort study enrolled 88 patients with Graves' hyperthyroidism and 68 with toxic nodular goiter from endocrine outpatient clinics at two Danish university hospitals. The patients were treated with antithyroid drugs, radioactive iodine, or surgery. Disease-specific and generic HRQoL were assessed using the thyroid-related patient-reported outcome (ThyPRO) and the Medical Outcomes Study 36-item Short Form (SF-36), respectively, evaluated at baseline and six-month follow-up. The scores were compared with those from two general population samples who completed ThyPRO (n = 739) and SF-36 (n = 6638). Baseline scores for patients with Graves' hyperthyroidism and toxic nodular goiter were significantly worse than those for the general population scores on all comparable ThyPRO scales and all SF-36 scales and component summaries. ThyPRO scores improved significantly with treatment on all scales in Graves' hyperthyroidism and four scales in toxic nodular goiter, while SF-36 scores improved on five scales and both component summaries in Graves' hyperthyroidism and only one scale in toxic nodular goiter. In Graves' hyperthyroidism, large treatment effects were observed on three ThyPRO scales (Hyperthyroid Symptoms, Tiredness, Overall HRQoL) and moderate effects on three scales (Anxiety, Emotional Susceptibility, Impaired Daily Life), while moderate effects were seen in two ThyPRO scales in toxic nodular goiter (Anxiety, Overall HRQoL). However, significant disease-specific and generic HRQoL deficits persisted on multiple domains across both patient groups. Graves

The prevalence of goiter was evaluated in a sample from the schoolchildren population of Reggio Emilia district. 1020 children underwent physical examination of thyroid gland and thyroid ultrasonography for determination of thyroid volume. Urinary iodine excretion (UIE) was measured in 837/1020 (82.1%). Iodine content was measured in water samples collected from 65 wells and 12 springs all around the district. The prevalence of goiter according to thyroid gland palpation was 26.2%. Thyroid volume was 4.74 +/- 1.87 ml, and the median UIE value 85 micrograms/l. According to the UIE classes as defined by WHO, 57.8% of all subjects showed a UIE less than 100 micrograms/l. In 57 out of 65 wells and in all the 12 springs examined, iodine was completely absent. In the remaining 8 wells, only iodine traces were found. Based on the results of physical examination of the thyroid gland, Reggio Emilia district should be regarded as an endemic goiter area. Nevertheless, thyroid volume measurement by ultrasound indicates that goiter prevalence may be markedly overestimated by palpation. The high prevalence of subjects featuring an increased thyroid volume, the low median UIE value and the poor iodine content in the local reservoirs of drinkable water suggest the opportunity for iodine prophylaxis in the Reggio Emilia district.

Objective: To study the relationship between changes of serum TMA, TGA levels and the size of goiter in patients with Graves' disease treated with 131 I. Methods: Serum TGA, TMA levels were measured with CLIA in 327 patients with Graves' disease both before and six months after 131 I treatment. These 327 patients were of three groups: Goiter I degree n=97, II degree n=128, III degree n=102. Results: In patients with I degree goiter,the serum TGA and TMA levels were only insignificantly increased after the 131 I treatment with an early hypothroidism rate of 21.44%. In patients with II degree goiter, the serum TGA and TMA levels were significantly increased after treatment (P 131 I. (authors)

A reliable decrease of triiodotyronine in blood cerum in the region with moderately increased intake of fluorine with drinking water (1.2-3.1 mg/l) is detected. This results in increase of euthyroid goiter among population by 14-16 times, of nodular - by 6 times. In the studied area there is indirect dependence between function of thyroid gland and degree of its hyperplasia, i.e., the larger is the gland, the weaker is its ability to produce hormones. The practical significance of detected dependence lies in the fact, that in surgical removal of the nodes (malignant cases are excluded) not only morphological but functional criteria as well of the gland increase should be taken account of. Such approach to nodular goiter therapy promotes sufficient reduction of postoperative hypothyrosis. These peculiarities of the ratio between the thyroid gland hyperplasia degree and its function under conditions of studied area must be taken account of when selecting methods of conservative treatment of patients with euthyroid goiter

An outbreak of Salmonella enterica serotype Choleraesuis enteritis occurred in two juvenile goitered gazelles and an adult Malayan tapir over a period of 5 wk at the Minnesota Zoo. Diagnosis was made postmortem on one gazelle and one tapir, and a second gazelle was diagnosed via fecal culture. The death of the tapir was attributed to S. enterica serovar Choleraesuis septicemia, while salmonellosis was considered to be a contributing factor besides ostertagiasis for the death of one goitered gazelle and for the diarrhea of another goitered gazelle. A third gazelle became ill in the same time period, but Salmonella infection was not confirmed by culture. All exhibited the clinical signs of profuse, watery diarrhea. The gazelles developed a protein-losing enteropathy, and the tapir showed signs of sepsis and endotoxemia. Serotyping and pulsed-field gel electrophoresis revealed the Salmonella isolates to be indistinguishable from each other. One year prior to this outbreak, Salmonella sp. was cultured from a Visayan warty pig (Sus cebifrons) housed in the same building as the tapir. After further investigation into the outbreak, spread of this pathogen was speculated to be associated with human movement across animal areas.

Full Text Available Thyroid disorders are frequently encountered. The diagnosis is straightforward unless clinical or laboratory findings are inconclusive and/or perplexing. Hyperthyroidism due to a thyrotropin-secreting pituitary adenoma rarely occurs and symptoms due to thyroid hormone excess are subtle. The presentation of the disease becomes unusual when co-secretion of other hormones with thyrotropin or concomitant thyroid parenchymal pathology exist. We present the case of a 63-year-old female patient with thyrotropinoma co-secreting growth hormone and multinodular goiter. She developed hyperthyroidism first due to thyrotropinoma and later due to a toxic nodule. Herein, we discuss the diagnostic and therapeutic challenges of hyperthyroidism with atypical presentation.

Full Text Available OBJECTIVES: We comprehensively estimated the prevalence of goiter and thyroid nodules (TNs before and after the implementation of the Universal Salt Iodization (USI program in mainland China and provided information for creating effective health policies. METHODS: PubMed, Google Scholar, CNKI, Chinese Wanfang and Chongqing VIP databases were searched for relevant studies from Jan 1985 to Feb 2014. Data from eligible citations were extracted by two independent reviewers. All analyses were performed with Stata 11.0 and SPSS 17.0. RESULTS: Eligible articles (N = 31; 4 in English and 27 in Chinese included 52 studies (15 about goiter rates made before 1996 and 14 afterwards, and 23 about TNs. Our meta-analysis suggests a pooled prevalence for goiter before and after 1996 and for TNs of 22.8% (95% CI: 15.3%, 30.3%, 12.6% (95% CI: 9.4%, 15.8% and 22.7% (95% CI: 18.3%, 27.0%, respectively. Egger's test of three independent categories revealed no evidence of publication bias (p = 0.101, 0.148 and 0.113, respectively. CONCLUSIONS: The prevalence of goiter was reduced by almost half after 1996 in mainland China, so the USI program was considered beneficial. However, subgroup analysis suggests that both insufficient and excess iodine may be associated with goiter. The prevalence of goiter and TNs increased significantly after 2002, suggesting a risk of excessive iodine intake. Thus, salt iodization standardizations should be set according to local conditions.

Full Text Available Appropriate airway management is an essential part of anesthesiologist′s role. Huge goiters can lead to distorted airway and difficulty in endotracheal intubation. In this report, we present a case of a 67-year-old woman with a huge toxic multinodular thyroid swelling, gradually increasing in size for last 20 years, where trachea was successfully intubated. She had a history of deferred surgery in June 2007 due to inability to intubate, despite 5-6 attempts using different laryngoscopes, bougie, and stylet. Patient was re-admitted in December 2011 for the surgery and was successfully intubated this time with help of fiberoptic intubation using loco-sedative technique. Patient was electively kept intubated postoperatively in view of chances of tracheomalacia due to prolonged large goiter. She was extubated successfully on post-op day 2 after demonstration of leak around trachea following tracheal tube cuff deflation. The different techniques of managing the difficult airway in these patients are discussed.

Full Text Available Goiter is an enlargement of the thyroid gland in the anterolateral part of the neck. It is estimated that approximately 3 % of the population worldwide suffer from this condition, although the incidence of nodular goiter has decreased in some countries due to the intake of iodized salt and iodine-rich food. A case of a 59 year-old female patient who attended consultation with an enlargement of the neck, accompanied by weakness, palpitations and dysphagia is presented. After being examined, she underwent surgery which confirmed the diagnosis of intrathoracic goiter. Since this is a rare pathology, it is of scientific interest for professionals dealing with the study and treatment of thyroid conditions.Se denomina bocio al aumento de volumen de la glándula tiroides en la región antero-lateral del cuello. Se calcula que aproximadamente el 3 % de los pobladores del mundo lo tienen, aunque la incidencia del bocio nodular ha disminuido debido a la ingestión en algunos países de sal yodada y alimentos ricos en yodo. Se presenta el caso de una paciente de 59 años que acudió a consulta por presentar aumento de volumen del cuello, acompañado de decaimiento, palpitaciones y disfagia, la cual después de ser estudiada en consulta fue intervenida quirúrgicamente, en la que se corroboró el diagnóstico de un bocio endotorácico. Por ser esta patología poco frecuente, se considera de interés científico para los profesionales dedicados al estudio y tratamiento de las afecciones tiroideas.

Thyroid metastasis of lung cancer is rarely observed in clinical practice. The primary cancers which metastasize to the thyroid gland are mostly renal cell carcinoma, lung cancer, and breast cancer. Transient destructive thyrotoxicosis is caused by massive metastasis of extrathyroid tumors. We herein present a case report of a patient with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. A 66-year-old man complained of swelling around the right side of the neck, dyspnea, progressive weight loss, and palpitation starting since 3 months before his admission. The patient was diagnosed with small cell carcinoma of lung with metastasis to the thyroid and thyrotoxicosis due to toxic multinodular goiter. The case report presented here illustrates the challenge of making a definitive and adequate diagnosis, particularly if the patient presents with 2 potential causes of thyrotoxicosis. Thyroid scintigraphy is an important tool for differential diagnosis of thyrotoxicosis.

In 200 patients follow-up examinations were performed up to one year after radioiodine therapy (RITh) with individual dose calculation. The mean applied dose was significantly lower in patients with immunogenic hyperhyroidism (Graves' disease) as compared to patients with non-immunogenic hyperthyroidism (disseminated/multifocal autonomy, HYDA). In Graves' disease the rate of recurrent hyperthyroidism was significantly higher and that of posttreatment hypothyroidism lower. Considering the high recurrence rate in Graves' disease a higher dose, e.g. 150 Gy, seems to be appropriate. In patients with HYDA who received antithyroid drugs during RITh, recurrence of hyperthyroidism appeared slightly more, and posttreatment hypothyroidism slightly less, frequent. The efficiency of RITh was not significantly reduced by additional treatment with antithyroid drugs. Posttreatment hypothyroidism in patients with euthyroid goiter and disseminated/multifocal autonomy (EUDA) occurred significnatly more frequent if the basal TSH level was ≥ 0.5 μIE/ml before therapy. The goiter size was reduced independent of the basal TSH level. In HYDA patients after thyroid surgery recurrence appeared less, and in those with EUDA posttreatment hypothyroidism significantly more, frequent. A lower dose seems to be suitable in patients who underwent thyroid surgery before. In patients with focal autonomy after RITh no recurrence of hyperthyroidism was observed. In 9% a suppressed basal TSH level indicating persistent autonomy was seen. Posttreatment hypothyroidism in focal autonomy appeared only in patients without manifest hyperthyroidism before RITh and was significantly more frequent in this group. In patients with focal autonomy who developed hypothyroidism the dose calculation was based on a significantly higher volume of the adenoma. (orig./MG) [de

A group of patients with nodal euthyroid goiter (NEG (40 patients and a group of patients with nodular toxic goiter (NTG (40 patients were formed to compare clinical and morphological criteria of NCG growth to/with development of functional autonomy (FA. All patients were conducted research including physical examination, thyroid palpation, ultrasound, blood level of TSH and T4, scintigraphy, aspiration (needle biopsy, immunocytological and immunohistological reactions and statistics. In the study the method of indirect immunoperoxidase reaction with monoclonal rat/mouse antigens to Ki-67, TSH, galectin-3, Apo-test (“Dako Corporation”, “Novocastra Laboratories Ltd.” was used. Results. 1. In NEG expression of cell proliferation marker Ki-67 for certain rises pro rata to increase of proliferation degree, and in NTG grows according to FA development. 2. Apoptosis expression in NEG decreases according to degree of thyrocytes in a nodule, but in NTG falls pro rata to accumulation of thyroid FA. 3. Positive reaction for TSH in NEG tissue was found in 100%, whereas negative reaction for this receptor in NTG tissue was observed in 81% of all cases. 4. Galectin-3 was expressed in focuses of severe dysplasia of thyroid nodes tissue comparable to galectin-3 expression in the tissue of high-grade differentiated adenocarcinomas. Summary/conclusion. 1. Severe and moderate expression of Ki-67 and mild or negative immunomorphological reaction for Apo-test allows to refer such kinds of nodules to fast-growing/rapid-growing ones. 2. Reliable negative expression TSH receptor in the tissue of NCG is evidence of FA development and is an indication for a treatment of radioactive iodine or for an operation. 3. Galectin-3 probably is an early marker of malignant transformation in thyroid tissue. 4. Having conducted complex

The function of the adult thyroid is regulated by thyroid-stimulating hormone (TSH), which acts through a G protein–coupled receptor. Overactivation of the TSH receptor results in hyperthyroidism and goiter. The Gs-mediated stimulation of adenylyl cyclase–dependent cAMP formation has been regarded as the principal intracellular signaling mechanism mediating the action of TSH. Here we show that the Gq/G11-mediated signaling pathway plays an unexpected and essential role in the regulation of th...

113 patients with nodular goiter were studied cytologically by needle aspiration for differential diagnosis at the department of internal medicine, Chungnam National University Hospital since October 1980 till July 1981, and the final diagnosis taken from biopsies were compared with the cytologic method on the 44 cases who received operation. The results were obtained as follows: 1. Among the 113 cases of total patients, male were 15 cases (13.3%) and female were 98 cases (86.7%) and the sex ratio (M : F) was 1 : 6.5. The peak age incidence was in the third decade followed by forth and second decades. 2. The findings of cytological diagnosis in 113 cases showed benign adenoma in 69 cases (61.1%), subacute and chronic thyroiditis in 22 cases (19.5%), papillary carcinoma in 15 cases (13.3%) and follicular carcinoma in 7 cases (6.2%), respectively, and 48 cases (69.6%) of the adenomas and 2 cases (9.1%) of papillary carcinomas showed combined cystic degeneration of the nodules. 3. The diameter of the nodules by palpation revealed within 2-5 cm in 88 cases (77.9%) out of 113 cases, below 2 cm in 17 cases and over 5 cm in 8 cases and there were no significant relationship between the size of the nodule and disease entity. 4. The findings of thyroid scintigram using 131 I in 113 cases of nodular goiter showed 'cold nodule' in 111 cases (98.2%) and normal scan (radioactivity) in 2 cases (1.8%) which showed adenoma in cytology and there was no cases with h ot nodule'. 5. The thyroid functions of the 113 cases revealed as euthyroidism in 108 cases (95.6%), hypothyroidism in 2 cases (2.7%) in adenomas but there was no evidence that the nodules of the above 3 cases were the reason of hyperthyroidism. 6. In 44 operated cases, the histological diagnosis revealed 23 cases of adenoma out of 27 cases (85.2%) who were diagnosed as adenoma by cytology and 15 cases of malignancy out of 17 cases (88.2%), and the overall diagnostic accuracy of aspiration cytology was 86.4%.

A screening program for congenital hypothyroidism (CH) was performed in a severe endemic goiter area, Chengde district including 7 counties, after treatment with Iodine enriched salt, and Beijing city as a control area. From May 1985 to Sep. 1991, 26570 newborns in Beijing city and 16227 in Chengde were screened. The incidence of primary hypothyroidism in Beijing city was 1/8800 and that in Chengde 1/8100. Of all the 5 Ch detected, 3 from Beijing city and 2 from Chengde, were thyroid dysgenesis. Not a single case of endemic goiter cretinism (including both myxedematous and neurological cretinism) was found in our study. We conclude that Iodine deficiency is the only cause of endemic cretinism and this problem can be solved by Iodine enriched salt treatment

Full Text Available In adolescents with diffuse nontoxic goiter (DNG, who live in the condition of mild iodine deficiency, in a questionnaire study there was analyzed the diet and its influence on the level of vitamins and minerals. It was found that the deficiency of food fish and meat is accompanied by a decrease in the level of B1, B2 and E vitamins. Use for cooking iodine salt was associated with higher levels of selenium and vitamin A in adolescents with DNG. Goiter degree II–III was rarely diagnosed among them. The inclusion of products of animal origin, seafood and iodine salt in the diet of children and adolescents, who live in the condition of a mild iodine deficiency, is necessary for the prevention and treatment of DNG. In case of combined deficiency of iodine, selenium, and vitamins, especially in the absence of adequate nutrition, the complex therapeutic measures must include preparations of potassium iodide, selenium, vitamins A and group B.

Full Text Available Iodine deficiency is a national health problem in India and we have recently reported on the severity of IDD in adults and children in Gujarat province. The aim of this study was to determine the utility of thyroid ultrasonography to detect goiter in adults from an iodine-deficient population of Gujarat. We studied 472 adults selected by random household surveys. Data were collected on height, body weight, mid-upper arm circumference, thigh circumference, triceps skinfold thickness, thyroid size (palpation and ultrasonography, and diet. Casual urine samples for iodine (UI and blood spots for TSH estimation were obtained. Endemic goiter is a major public health problem in Gujarat State, India and is probably caused by multiple factors including iodine deficiency, malnutrition, and other dietary goitrogens. These results indicate that thyroid US consistently detects goiter in adults despite a diminished thyroidal response to variable goitrogenic stimuli.

The thyroglobulin (TG) gene is organized in 48 exons, spanning over 270 kb on human chromosome 8q24. Up to now, 62 inactivating mutations in the TG gene have been identified in patients with congenital goiter and endemic or non-endemic simple goiter. The purpose of the present study was to identify and characterize new mutations in the TG gene. We report 13 patients from seven unrelated families with goiter, hypothyroidism and low levels of serum TG. All patients underwent clinical, biochemical and imaging evaluation. Single-strand conformation polymorphism (SSCP) analysis, endonuclease restriction analysis, sequencing of DNA, genotyping, population screening, and bioinformatics studies were performed. Molecular analyses revealed seven novel inactivating TG mutations: c.378C>A [p.Y107X], c.2359C>T [p.R768X], c.2736delG [p.R893fsX946], c.3842G>A [p.C1262Y], c.5466delA [p.K1803fsX1833], c.6000C>G [p.C1981W] and c.6605C>G [p.P2183R] and three previously reported mutations: c.886C>T [p.R277X], c.6701C>A [p.A2215D] and c.7006C>T [p.R2317X]. Six patients from two families were homozygous for p.R277X mutation, four were compound heterozygous mutations (p.Y107X/p.C1262Y, p.R893fsX946/p.A2215D, p.K1803fsX1832/p.R2317X), one carried three identified mutations (p.R277X/p.C1981W-p.P2183R) together with a hypothetical micro deletion and the remaining two siblings from another family with typical phenotype had a single p.R768X mutated allele. In conclusion, our results confirm the genetic heterogeneity of TG defects and the pathophysiological importance of altered TG folding as a consequency of truncated TG proteins and missense mutations located in ACHE-like domain or that replace cysteine.

This study is aimed to explore the combined use of goiter dispersion formula and antithyroid drugs in the treatment of patients with neurologic manifestations of Graves' disease by examining its modulating effects on patients' cytokines. A total of 80 patients with Graves' disease were randomly divided into treatment and control groups. Patients of the treatment group received goiter dispersion formula and antithyroid drugs (methimazole or propylthiouracil), whereas those of the control group received antithyroid drug alone. FT3, FT4, and TSH contents were detected by chemiluminescence immunoassay at pre- and post-treatment; interleukin (IL)-2, IL-8, and IL-17 serum levels before and after the treatment were detected by radioimmunoassay; thyroid B-mode ultrasound and liver and renal function tests were performed in all patients of both groups. An additional cohort of 40 healthy subjects was recruited for baseline measurement. All the enrolled patients completed the trial. The effective treatment rate was higher in the treatment group than in the control group, of which the difference was statistically significant (treatment group, 95%; control group, 75%, p Graves' disease comparing with those in healthy subjects (p Graves' disease by modulating IL-2, IL-8, and IL-17. The data supported the rationale for the use of goiter dispersion formula in Graves' disease treatment.

Full Text Available Introduction: Intra-thoracic goiter refers to the extension of enlarged thyroid tissue into the thoracic inlet. This condition can produce symptoms of compression on adjacent organs and can sometimes be accompanied by malignant transformation. Therefore surgical treatment is almost always necessary. In order to remove the pathology with the fewest post-operative complications, selection of the appropriate surgical approach is essential. In this study we aimed to detect the criteria which help us select the best therapeutic approach.   Materials and Methods: In this retrospective study, 82 patients with intra-thoracic goiter were investigated. Their data were extracted from medical records and analyzed using SPSS software.   Results: Overall 82 patients, 18 (21% males and 64 (78% females with mean age of 56.38 years were studied. The most common clinical symptoms were mass (95% and dyspnea (73%. In most patients, the surgical approach was cervical (90.2%, while 9.8% of patients required an extra-cervical approach. Post-operation complications were observed in 17.1% of patients; the most common being transient recurrent laryngeal nerve paralysis (4.9%. Malignancy was reported in the histopathology of seven patients (8.5%. The most common malignant histopathology was papillary thyroid carcinoma (7.3%. Extension of the thyroid tissue below the uppermost level of the aortic arch was significantly correlated with the need for an extra-cervical approach to surgery (P

Constitutive activation of the cAMP pathway stimulates thyrocyte proliferation. Gain-of-function mutations in Gsalpha protein have already been identified in thyroid nodules which have lost the ability to trap iodine. In contrast, most of the studies failed to detect somatic activating mutations in the thyrotropin receptor (TSH-R) in non-hyperfunctioning thyroid tumors. The aim of this study was to screen for mutations TSH-R exon 10, encoding the whole intracytoplasmic area involved in signal transduction, and Gsalpha exons 8 and 9, containing the two hot-spot codons 201 and 227, in a subset of non-hyperfunctioning nodules from multinodular goiter. Identified by matching ultrasonography and scintiscan, 22 eufunctioning (normal 99Tc uptake) and 15 nonfunctioning (decreased 99Tc uptake) nodules from 27 non-toxic multinodular goiters were isolated. After DNA extraction, TSH-R exon 10 was analyzed by direct sequencing of the PCR products and Gsalpha exons 8 and 9 by Denaturing Gradient Gel Electrophoresis. No mutation of TSH-R or Gsalpha was detected in the 37 nodules analyzed. This absence of mutation, despite the use of two sensitive screening methods associated with the analysis of the TSH-R whole intracytoplasmic area and Gsalpha two hot-spot codons, suggests that TSH-R and Gsalpha play a minor role in the pathogenesis of non-toxic nodules from multinodular goiters.

Many studies have been carried out to determine G(s) alpha and TSHR mutations in autonomously functioning thyroid nodules. Variable prevalences for somatic constitutively activating TSHR mutations in hot nodules have been reported. Moreover, the increased prevalence of toxic multinodular goiters in iodine-deficient regions is well known. In Turkey, a country with high incidence rates of goiter due to iodine deficiency, the frequency of mutations in the thyrotropin receptor signal transduction pathway has not been evaluated up to now. In the present study, a part of the genes of the TSHR, G(s)alpha and the catalytic subunit of the PKA were checked for activating mutations. Thirty-five patients who underwent thyroidectomy for multinodular goiters were examined. Genomic DNAs were extracted from 58 hyperactive nodular specimens and surrounding normal thyroid tissues. Mutation screening was done by single-strand conformational polymorphism (SSCP) analysis. In those cases where a mutation was detected, the localization of the mutation was determined by automatic DNA sequencing. No G(s)alpha or PKA mutations were detected, whereas ten mutations (17%) were identified in the TSHR gene. All mutations were somatic and heterozygotic. In conclusion, the frequency of mutations in the cAMP signal transduction pathway was found to be lower than expected in the Turkish population most likely because of the use of SSCP as a screening method and sequencing only a part of TSHR exon 10.

Full Text Available Graves’ disease (GD may be observed as an infrequent adverse effect after radioiodine therapy (RAIT for toxic thyroid adenoma (TA and toxic multi nodular goiter (MNG. We present a case of a 55-year-old male with a toxic nodule who was treated with RAI. After therapy, the patient’s serum free triiodothyronine (fT3 and free thyroxine (fT4 levels gradually increased. Antithyroid peroxidase (TPOAb, antithyroglobulin (TgAb and TSH-receptor antibodies (TRAb were also positive. Thyroid scintigraphy revealed diffuse intense uptake after four months of RAIT. Radiation-induced GD should be considered in patients with aggravated hyperthyroidism 3-4 months after therapy.

Background and purpose: The incidence of retrosternal goiter (Rg) varies from 2% to 26% of all thyroidectomies, depending on the defining criteria . There are no clear guidelines to identify patients that require an intrathoracic approach. So, we tried to correlate, between the size and/ or anatomical site of the RSG based on preoperative CT findings and the surgical approaches used, aiming at defining those patients with RSG who are in need for thoracic approach. Patients and methods: Out of 1481 patients underwent thyroidectomy at the National Cancer Institute (NCI), Cairo University, between January 2000 and December 2009, only 73 (4.93%) of them had retrosternal extension. Demographic, clinical, operative, anatomical, and pathological data of patients with RSG were recorded and analyzed. Results: The intraoperative extension of the goiter correlated with the extension seen in the CT in all except two patients. Laterality and longitudinal extension found in preoperative CT, correlated well with the surgical findings. The approach used was cervical in 66 cases (90.4%); combined approach in six patients (8.2%). Pure thoracic (full sternotomy) was used alone in one case (1.4%). Extension of the RSG down to or below the arch was associated with an increased risk of using a thoracic approach p< 0.0001. Conclusion: Preoperative CT, can be used effectively to guide the indications for using a thoracic approach. Reaching the aortic arch or beyond and loss of fat planes in CT, recurrent and malignant disease, are significant risk factors for using a thoracic approach.

Large Multinodular Toxic Goiter: Is Surgery Always Necessary?

2016-01-01

Full Text Available Patients suffering from multinodular toxic goiter (MNTG are candidates to thyroidectomy or radioiodine 131I (131I therapy. Thyroidectomy may be preferable especially when the volume of hyperfunctioning tissue is so large that a single administration of 131I is unlikely to cure the patient in terms of nodule’s volume reduction and thyroid function. We describe the case of a 71-year-old man suffering from thyrotoxic state for the presence of two large hyperfunctioning thyroid nodules. As the patient refused surgery, at first we administered 600 MBq dose of 131I, which was unable to solve hyperthyroidism and local compressive symptoms. Then, before administering another 131I dose, the patient underwent a laser ablation treatment (LAT in both nodules. After a significant shrinkage due to LAT, the patient received 400 MBq 131I. This procedure was able to definitely cure hyperthyroidism, to induce a significant reduction of nodules’ volume, and to render the patient asymptomatic for compressive symptoms. This case demonstrates that 131I preceded by LAT represents a valid alternative strategy to surgery, even in the presence of two large coexistent hot nodules.

Full Text Available Aim: The aim of this study was to investigate the prevalence of musculoskeletal manifestations in patients with thyroid dysfunction. Methods: One hundred and twenty-three patients (100 female, 23 male who visited the nuclear medicine department for thyroid gland scintigraphy were included in our study. According to thyroid hormone levels, patients were allocated into five categories: hyperthyroidism, subclinical hyperthyroidism, euthyroid, subclinical hypothyroidism, and hypothyroidism. Before neurological and musculoskeletal examinations, a standardized symptom questionnaire was completed including questions about sensory symptoms, muscle weakness, restricted joint mobility, musculoskeletal pain. Neurological examination, range of motion of joints, effusion or swelling of joints was assessed. Diagnosis of osteoarthritis was done by the clinical and radiological characteristics. The diagnosis of FMS was made according to criteria of American College of Rheumatology. According to the World Health Organization (WHO, a T-score ≤ -2.5 was classified as osteoporosis, whereas a T-score between -2.5 and -1.0 was classified as osteopenia. Thyroid status was determined by serum TSH levels. Results: Eighty-one percent of the patients were female (100 and 19% were male (23. Mean age of female patients was 49.99±15.27 years (range 20-87 and mean age of male patients was 61.8±12.33 years (range 34-88. When divided according to thyroid status, 21.1% (n=26 had hyperthyroidism, 21.1% (n=26 had subclinical hyperthyroidism, 49.6% (n=61 were euthyroid, 4.9% (n=6 had subclinical hypothyroidism and 3.3% (n=4 were hypothyroid. None of 59% of patients had any musculoskeletal diagnosis. Osteoporosis was the most common problem, affecting 23.7% of patients Conclusion: The presence of musculoskeletal symptoms in patients with goiter should be considered and investigated.

Patients treated with 10 mCi of I-131 for toxic diffuse goiter in the period January 1974--June 1976 were evaluated for development of hypothyroidism. Fifty percent were hypothyroid within 3 months and 69 percent within 1 year of treatment. Our data suggest that there is a higher incidence of hypothyroidism after standard doses of I-131 in the 1970s as contrasted with treatment groups in the 1950s and 1960s. The pathophysiology of this increased incidence is not known with certainty; however, infrequent use of thionamide medication, together with recent increases in dietary iodine, may render the gland more radiosensitive

Ochoa Torres, Francisco; Knight Bermudez, Hugh Gregorio; Alavez Martin, Ernesto

2004-01-01

131 I has proved to be the most efficient therapeutics in the treatment of diffuse toxic goiter (DTG). However, there is no consensus on the dose to be administered: fixed dose or according to the functional activity of the thyroid and its size. In order to evaluate the therapeutical results at a dose of 80 μCi/g of thyroid tissue, estimated by palpation and without having into account the functional activity of thyroid and whether they had received propylthiouracil (PTU) previously, 61 patients diagnosed by the clinic, as well as determinations of TSH and total T4, were studied in individuals aged 20-80 of both sexes, with a thyroid size over 30 g. The postoperative follow-up was performed every 2 months for 3 years by the same specialist and with identical procedures. The efficiency of the treatment with the first dose was 85.2 %. The frequency of hypothyroidism at 3 years of evolution was 29.5. The age of the patient, the sex, the goiter size and the treatment with PTU did not influence on the response to it. The advantages showed by the method were: high efficiency, the dose of 131 I may be easily calculated, simple application, decrease of the cost, since it is not necessary to assess the functional state of the gland, and reduction of visits

Diffraction-enhanced images (DEI) have been obtained using two silicon crystals. A first channel-cut silicon crystal using the Si(3 3 3) reflection is employed to reduce the divergence of the pre-monochromated Si(1 1 1) beam of the light line to 60 microradian (12 arcsec). A second channel-cut Si(3 3 3) crystal was used as a Bragg analyzer to obtain bright and dark field images by changing its angular position. This technique is ideally suited for soft-tissue imaging or objects with the same absorption coefficient interfaces. DEI was developed at the XRD-2 beamline at the Brazilian Synchrotron (LNLS) in Campinas-Brazil. Feasibility tests on acquired images, which allow the diagnosis of thyroid nodular goiter, were performed. This disease is ordinary. The tissue developed on the cervical area causes compression of the nearby structures and undesirable aesthetic deformities with worldwide distribution. DEI of the tissues were taken to observe their morphology and to compare with the microscopic analysis (histopathological). This technique allows cutting sections a hundred times thicker than conventional histological techniques allowing a complete vision of the disease morphology. DEI show details not clearly seen with conventional techniques

A 70-year-old male was referred with hyperthyroidism and multinodular goiter (MNG). Thyroid ultrasonography showed 2 nodules, one in the isthmus and the other in the left lobe, 51 and 38 mm in diameter, respectively. Neck CT showed a large MNG, thyroid scintigraphy showed increased uptake in the nodule in the left lobe, and fine-needle aspiration biopsy showed a benign cytology of the nodule in the isthmus. The patient declined surgery and was treated with methimazole. After being lost to follow-up for 3 years, the patient returned with complaints of dyspnea, dysphagia, and hoarseness; he was still hyperthyroid. Cervical CT showed a large mass in the isthmus and left lobe with invasion of surrounding tissues, the trachea, the esophagus, and the recurrent laryngeal nerve. Bronchoscopy showed extensive infiltration and compression of the trachea to 20% of its caliber. A tracheal biopsy revealed an anaplastic thyroid carcinoma. The tumor was considered unresectable, and radiotherapy was given. One month later, the patient died. The association between a toxic thyroid nodule and anaplastic thyroid carcinoma has apparently not been reported so far. PMID:25759806

No hypothyroidism after I-131 therapy in pts with toxic nodular goiter, treated under combined thyreostatic, thyreomimetic medication

Background. Treatment of toxic nodular goiter with 131-I is generally satisfactory and will cause a reversion of hyperthyroidism. To avoid the risk of thyrotoxic storm I-131 therapy is usually performed after pre-treatment with antithyroid drugs, which causes a TSH increase and functional recruitment of previously inhibited normal thyroid tissue. In this functional state both autonomous nodule(s) and normal tissue are irradiated after I-131 administration. This may be the reason of late hypothyroidism occurring in 15-25% of Pts. Aim of the study was the evaluation of a different pre-treatment modality with combined methimazole (10-20 mg) and Triiodo-thyronine (T3 - 60 μg) in order to treat pts in euthyroid state with suppressed TSH. Study protocol. After diagnosis of hyperthyroidism with autonomous functioning tissue the pts were put under thyreostatic medication. Two months later TSH was checked and if >0.5% U.I the T3 treatment was associated. After two more months, the TSH level was checked again and, if suppressed, the pt received I-131 therapy. Study population. 93 pts (74f, 19m - age 75±10) were consecutively enrolled. 24 pts had a toxic nodular goiter and 69 a multi nodular one, respectively; they were evaluated at diagnosis, at pre-treatment, two months after therapy and at late follow-up (3.1 ± 3.5 yrs). Methods: 557±225 MBq of I-131 (according to uptake determinations and gland weight) were administered. Methymazole was discontinued 3 days before treatment whereas T3 was maintained during I-131 therapy. Results: Euthyroidism was achieved after the first treatment in 71% of pts. At late follow-up TSH values over the normal range were observed in only 4 pts (4.3% - however all 4 pts had TSH level below 6 I.U.). Summaries of FT3 and FT4 values are presented. Conclusions: The treatment of toxic nodular goiter under combined thyreostatic-thyreomimetic treatment is a safe, well tolerated and effective procedure allowing a 71% success at the first treatment

131 I. has proved to be the most efficient therapeutics in the treatment of diffuse toxic goiter (DTG). However, there is no consensus on the dose to be administered: fixed dose or according to the functional activity of the thyroid and its size. In order to evaluate the therapeutical results at a dose of 80 ΜCi/g of thyroid tissue, estimated by palpation and without having into account the functional activity of thyroid and whether they had received propylthiouracil (PTU) previously , 61 patients diagnosed by the clinic, as well as determinations of TSH and total T4, were studied in individuals aged 20-80 of both sexes, with a thyroid size over 30 g. The postoperative follow-up was performed every 2 months for 3 years by the same specialist and with identical procedures. The efficiency of the treatment with the first dose was 85.2 %. The frequency of hypothyroidism at 3 years of evolution was 29.5. The age of the patient, the sex, the goiter size and the treatment with PTU did not influence on the response to it. The advantages showed by the method were: high efficiency, the dose of 131 I. may be easily calculated, simple application, decrease of the cost, since it is not necessary to assess the functional state of the gland, and reduction of visits

A 77-year-old woman was referred because of local reoccurrence of cancer of the breast. Chest x-ray showed a mediastinal tumor with dislocation of the trachea to the right. A Tc-99m pertechnetate scan showed irregular tracer uptake in an enlarged left lobe of the thyroid gland. Ultrasound confirmed...... the diagnosis of a nodular goiter with intrathoracic growth of the left lobe. A SPECT/CT scan of the mediastinum clearly showed that the soft tissue tumor was the left lobe of the thyroid gland, and not lymphatic metastases....

One hundred goitrous school children received 475 mg iodized oil by mouth, while 100 controls received mineral oil, on a double-blind basis. On follow-up 22 months later the urinary iodine had increased and goiter size had decreased in both groups, more strikingly in the iodine-treated children. There were no consistent differences between the two treatment groups in rate of somatic growth or performance on the Stanford-Binet and Bender tests. Because of the complexities introduced by increases in urinary iodine in the controls, we compared goiter reduction with improvement in IQ score in all children, regardless of group, and found a significant relationship (p = 0.014), particularly in girls (p = 0.029). We conclude that oral iodized oil is an attractive alternative to its injection but we recommend an approximate doubling of the dose used here for more effective control. Also, while our data are not conclusive, they support the possibility that correction of iodine deficiency may improve mental performance in school age children, particularly girls.

The surgical approach to primary hyperparathyroidism (HPT) is changing. In patients with a high probability to be affected by a solitary parathyroid adenoma (PA), a unilateral neck exploration (UNE) or a minimally invasive radio-guided surgery (MIRS) using the intraoperative gamma probe (IGP) technique have recently been proposed. We investigated the role of IGP in a group of 84 patients with primary HPT who were homogeneously evaluated before surgery by a single-day imaging protocol including 99mTcO4/MIBI subtraction scan and neck ultrasound (US) and then operated on by the same surgical team. Quick parathyroid hormone (QPTH) was intraoperatively measured in all cases to confirm successful parathyroidectomy. In 70 patients with scan/US evidence of a single enlarged parathyroid gland (EPG) and with a normal thyroid gland, MIRS was planned. In the other 14 patients, the IGP technique was utilized during a standard bilateral neck exploration (BNE) because of the presence of concomitant nodular goiter (11 cases) or multiglandular disease (MGD) (3 cases). The IGP technique consisted of the following: (1) in the operating room, a low 99mTc-MIBI dose (37 MBq) was injected intravenously during anesthesia induction; (2) subsequently, the patient's neck was scanned with the probe by the surgeon to localize the cutaneous projection of the EPG; (3) in patients who underwent MIRS, the EPG was detected intraoperatively with the probe and removed through a small, 2 to 2.5 cm skin incision; (4) radioactivity was measured on the EPG both in vivo and ex vivo, the thyroid, the background and the parathyroid bed after EPG removal. In patients with concomitant nodular goiter, the radioactivity was also measured on the thyroid nodules. Surgical and pathologic findings were consistent with a single PA in 78 patients, parathyroid carcinoma in 2, and MGD in 4. MIRS was successfully performed in 67 of the 70 patients (97.7%) in whom this approach was planned. It must be pointed out that

Full text: Introduction: In our experience and of the recent literature, the association of the recombinant TSH (rh TSH) in low doses, previously to 131 I has been value in MNG treatment. However we don't have an ideal approach on this disease. Objective: To compare two different options with rh TSH previously to fixed dose of 131 I (30 mCi) in BMN treatment. Patients and Methods: We have 18 patients in group 1 and 14 in group 2. The patients had similar age and volume goiter in both groups. They were submitted to the same diagnosis protocol: TSH, FT 4 , T 3 , Tg on days 0, 1, 2, 3, 5, 10, 30, 90, 180 and TPO ab, Tg ab and TRAB on days 0, 30, 90 and 180. The goiter was measured by helicoidal CT on days 0 and 180.The RAIU on 24 h after rh TSH was measured in both groups. The G 1 used rh TSH in two consecutive doses of 0,1 mg and the G 2 used an unique dose of 0,1 mg. Both groups were submitted to 30 mCi of 131 I 24 h after the last injection of rh TSH. Results: The increment of TSH level was bigger in group 1 than group 2 (33 times in G1 and 13 times in G2). Similar results were found on FT 4 ,T 3 and Tg levels. The hormones returned to base levels after 30 d on G1 and 90 d on G2. The RAIU 24 h peak was bigger on G1 than G2 (12% to 52% on G1 and 10,2% to 35% on G2). 39% patients on G1 and 21% on G2 had clinic thyrotoxicosis and actinic thyroiditis were prevalent in 33 % on G1 and 14% on G2. After six months 65% of patients on G1 were in hypothyroidism and 28% on G2. The reduction on goiter volume was similar in both groups: 40% on G1 and 45% on G2. Conclusion: The option with 1 injection of 0,1 mg rh TSH plus 131 I had similar efficiency on reduction of volume goiter however was safer than 2 injections of 0,1 rh TSH plus 131 I in MNG treatment.

We report a prospective study to evaluate the effect of antithyroid drugs containing the sulfhydryl radical on the outcome of I-131 (RAI) therapy. Twenty-four male patients with toxic diffuse goiter were assigned randomly into two treatment groups: Group A received RAI treatment while on antithyroid drugs after attainment of euthyroidism; Group B received no antithyroid drugs before, or when, RAI was given. Patients in each group received a dose of RAI calculated to deliver approximately 5000 rads per treatment. The incidence of hypothyroidism at 12 mo was 8% for Group A and 36% for Group B (p 0.45). The improved therapeutic outcome of patients in Group A suggests that further validation of the method in a larger patient population, including females, is warranted

Full Text Available BackgroundAnti-thyroid drug therapy is considered a treatment of choice for Graves' disease; however, treatment response varies among individuals. Although several studies have reported risk factors for relapse after initial treatment, few have assessed responsiveness during the early treatment period. Our study aimed to identify the clinical characteristics for responsiveness to methimazole.MethodsWe included 99 patients diagnosed with Graves' disease for the first time. Drug responsiveness was defined as the correlation coefficients between decreasing rates of free thyroxine level per month and methimazole exposure dose. According to their responsiveness to treatment, the patients were classified into rapid or slow responder groups, and age, sex, free thyroxine level, and thyrotropin binding inhibiting immunoglobulin (TBII titers were compared between groups.ResultsThe mean patient age was 44.0±13.5 years and 40 patients were male (40%. The mean TBII titer was 36.6±74.4 IU/L, and the mean free thyroxine concentration was 48.9±21.9 pmol/L. The rapid responder group showed higher TBII titer and free thyroxine level at diagnosis, while age, sex, smoking, and presence of goiter did not differ between the two groups. Logistic regression analyses revealed that high level of serum thyroxine, high titer of TBII, and absence of goiter were significantly associated with a rapid response, while age, sex, and smoking were not significant factors for the prediction of responsiveness.ConclusionIn patients with new onset Graves' disease, high level of free thyroxine, high titer of TBII, and absence of goiter were associated with rapid responsiveness to methimazole treatment.

Clinical examples of amyloid deposition in parathyroid glands are exceedingly rare and usually present as an incidental finding in a patient with amyloid goiter. Here, we present the first histologically documented case of parathyroid amyloid deposition that presented as a mass. The patient did not have hyperparathyroidism. The parathyroid gland was submitted for intra-operative frozen section and concern for medullary thyroid carcinoma was raised. An important histologic clue arguing against medullary thyroid carcinoma was the evenly dispersed nature of the amyloid. Histologic perinuclear clearing and parathyroid hormone immunohistochemistry confirmed parathyroid origin on permanent sections. The patient was also found to have associated amyloid goiter. Mass spectrometry of the amyloid showed it to be composed of kappa light chains. On further work-up, the patient was diagnosed with multiple myeloma. Awareness of parathyroid amyloid deposition is important as it is a histologic mimic of medullary thyroid carcinoma, especially on frozen section. Amyloid typing with evaluation for multiple myeloma in any patient with kappa or lambda light chain restriction is also important.

Full Text Available The Hospital de Clínicas organized a free program of goiter detection by palpation. This campaign was aimed at the population of the metropolitan area of Greater Buenos Aires (11 million inhabitants, with the prerequisite that each participant should be quite unaware whether he/she was a carrier of any thyroid disease. Attendees were split into two groups, i.e., Random and Induced. The former consisted of 542 individuals who came to consultation due to mere curiosity, while the latter involved 500 subjects, comprising consanguineous family members of patients with thyroid disorders and also individuals who suffered from other ailments. Ages ranged from 2 to 85 years. In the Random Group, goiter prevalence of 8.7% was observed, while in the Induced Group it climbed to 14.4%. Since both groups were mostly made up of women (87.2%, a correction based on the masculinity index was applied to members of the Random Group. Thus, the total observed prevalence of goiter was 6%, diffuse goiters corresponding to 3.5% and nodular ones to 2.5%. The frequency of nodules increased with age, 90.5% occurring in those over 40 years. In the Induced Group, goiter prevalence among relatives of patients with thyroid disorders proved to be 13.1%, rising to 17.8% in those who suffered from other complaints. The epidemic data presented herein are the first arising from a screening survey carried out in a large iodine-sufficient population of the southernmost tip of the American continent. These results are useful to build up the world map of goiter prevalence in non-endemic areas.El Hospital de Clínicas organizó un programa gratuito para la detección de bocio por palpación.

Relatively little is known about the cytological characteristics of hyperfunctioning (hot) thyroid nodules. Concern has been expressed that fine-needle aspiration (FNA) identifies hot nodules as follicular tumors or indeterminate, and as a consequence patients could be unnecessarily referred for surgery. Between 1979 and 1996, thyroid FNA was performed on 829 patients. Result of thyroid scan was available in 326; 69 (21%) patients had hot, and 257 (79%) had warm or cold thyroid nodules. Nodules in each of these major groups were divided into 2 subgroups: clinically solitary nodules and dominant nodules in multinodular goiters (MNG). The frequencies of adequate versus inadequate FNA samples, and of conclusive versus indeterminate FNA results were determined separately for each of the groups and subgroups. In addition, patients with hot nodules and overt hyperthyroidism were identified and evaluated separately. Bivariate analyses were performed for the frequency of adequate versus inadequate smears and conclusive versus indeterminate results between hot, toxic, and cold-warm nodules, and between solitary nodules and MNG. The frequency of adequate aspirations and conclusive results in the various groups and subgroups was found to be statistically indistinguishable. In conclusion, the yield of adequate samples and the rate of conclusive results of FNA in thyroid nodules is similar, irrespective of the functional state or of goiter presentation. Hot thyroid nodules do not seem to produce an increase in the rate of inadequate or indeterminate FNA results, and therefore, do not affect the overall performance of thyroid FNA.

We measured Tvol using ultrasonography in 8,314 children and measured UIC (4,767 subjects and salt iodine (10,184 samples using methods recommended by the World Health Organization. Tvol was used to calculate TGR based on the reference criteria specified for sex and body surface area (BSA.TGR decreased from 55.2% in 1997 to 1.0% in 2009, and geometric means of Tvol decreased from 3.63 mL to 1.33 mL, along with the UIC increasing from 83 μg/L in 1995 to 407 μg/L in 1999, then decreasing to 243 μg/L in 2005, and then increasing to 345 μg/L in 2011. In the low goiter population (TGR 300 μg/L was associated with a smaller average Tvol in children.After IDD elimination in Jiangsu province in 2001, lower TGR was associated with smaller average Tvol. Average Tvol was more sensitive than TGR in detecting the fluctuation of UIC. A UIC of 300 μg/L may be defined as a critical value for population level iodine status monitoring.

The function of the adult thyroid is regulated by thyroid-stimulating hormone (TSH), which acts through a G protein-coupled receptor. Overactivation of the TSH receptor results in hyperthyroidism and goiter. The Gs-mediated stimulation of adenylyl cyclase-dependent cAMP formation has been regarded as the principal intracellular signaling mechanism mediating the action of TSH. Here we show that the Gq/G11-mediated signaling pathway plays an unexpected and essential role in the regulation of thyroid function. Mice lacking the alpha subunits of Gq and G11 specifically in thyroid epithelial cells showed severely reduced iodine organification and thyroid hormone secretion in response to TSH, and many developed hypothyroidism within months after birth. In addition, thyrocyte-specific Galphaq/Galpha11-deficient mice lacked the normal proliferative thyroid response to TSH or goitrogenic diet, indicating an essential role of this pathway in the adaptive growth of the thyroid gland. Our data suggest that Gq/G11 and their downstream effectors are promising targets to interfere with increased thyroid function and growth.

Limited value of delayed radiothallium image in the diagnosis of nodular goiter

To test whether delayed thallium image can improve the diagnostic accuracy of thyroid tumor, we have reviewed 35 patients with cold nodules of proven histopathology. Early and delayed images were taken 10-20 min and 3-4 hr postinjection, respectively. In this study, a thyroid nodule was interpreted as malignant if it had normal or increased uptake on early scan and more residual radioactivity than paranodular tissue on delayed scan. In the eighteen patients who had carcinoma, a disappointing 44% false negative rate was observed. No significant difference was seen between retention-positive and negative cases in tumor size or histological type of cancer. Nor could any demographic bias explain the low sensitivity. Of the six false negatives, macroscopic cystic degeneration was seen in two cases, but tumors in the other four were grossly solid. Considering the histological heterogeneity often seen within a thyroid tumor, the portion with increased retention of radiothallium may be too small to be detected in the false negative cases. Furthermore, 3 false positive readings were obtained in 17 patients with benign conditions. We conclude that the contribution of the delayed thallium image was quite limited in predicting or ruling out malignancy in nodular goiters. (author)

The total goitre rate in Yemen declined by half after the country adopted universal salt iodisation in 1995. We investigated the recent epidemiology, pathalogy, and management of goiter so as to evaluate changes since the initiation of salt iodisation programme. We also sought to determine the effect of new diagnostic tools in the pre-operative work-up of surgically treated patients. Data were collected from the records of 667 patients with goitre seen in Kuwait University Hospital between 1997 and 2001. Females constituted 92.5% (n=617) of the series. The mean age of all patients was 35.2+-11.58 years range (13 to 90 years). Most patients (93%) came from highland areas with an average altitude of 2000 to 2600 meters above sea level. The average duration since patients noticed swelling untill the diagnosis was made was about 4 years. Multinodular bilateral swelling was the most common clinical finding (44.9%), while solitary nodules constituted the least common (17.4%). The most common associated symptom was dyspnoea (20.5%). The most common histopathological finding was nodular and colloid goitre (62.8%), while malignancy accounted for 17.7%. Subtotal thyroidectomy was the most frequent procedure, and the most common postoperative complication was hypocalcaemia. Goitre is a national problem in Yemen. The late presentation, which may be important in malignant transformationof the thyroid gland, makes surgery inoperative. The salt iodisation programme has been associated with a decrease in the malignancy rate. Yemen is the great need of experienced cytologists and radiologists to increase the efficacy of fine needle aspiration cytology and ultrasonography in the diagnosis of thyroid lesions. Patients need to be educated about the importance of post-operative follow up. (author)

Radioiodine therapy in toxic multinodular goiter- the influence of carbimazole therapy and dietary iodine on relapse rates

Full text: The relapse rate of radioiodine therapy in toxic multinodular goiter (TMNG) is reported to be around 34% at one year. The effect of antithyroid drugs on the response rate is controversial with studies reporting a higher relapse rate in patients pretreated with antithyroid drugs. Other studies report no influence of pretreatment with antithyroid drugs. The thyroid clinic at Tata Main Hospital is a referral center for thyroid disorders in Jamshedpur. 63 patients of TMNG (Group A) were treated with Radioiodine between 1995-2003. The demographic profile of these patients was as follows: M/F- 38%: 62%, 76% of patients were above 40 years, 85% had been on anti-thyroid drugs for more than 18 months. Fixed dose radioiodine in an oral dose varying from 5-10 mCi was given in all patients of Group A. 32.4 % of patients continued to be toxic or relapsed after a period of euthyroid status within 1 year of Radioiodine therapy. A change in protocol for radioiodine therapy was introduced in 2003. This included withdrawal of antithyroid drugs for one month before radioiodine therapy and the use of noniodized salt and abstinence from seafood in diet during this period. 33 TMN Goiter patients (Group B) followed this protocol before receiving Radioiodine. The dose of Radioiodine remained 5-10 mCi. The age and sex profile of Group A and B were comparable. However, Group B patients had been on antithyroid drugs for a shorter period (p< 0.001). The dose of Radioiodine in 94% of Group B patients was between 7-10mCi, whereas this was 63.4% in Group A. The rest of the patients had received a dose between 5-7 mCi. The relapse rate in Group B was 9.1% compared to 32.4% in Group A. Improvement in response rates with increase in Radioiodine dose remains controversial.P PThe better response rate in Group B patients may be attributed to the withdrawal of antithyroid drugs for one month before therapy and the reduction in dietary intake of Iodine for a month before therapy. However, a

Full Text Available Blunt chest trauma (BCT is a common clinical presentation seen in emergency departments. Few cases of cardiac conduction abnormalities due to BCT have been reported in the medical literature. This dysrhythmias may present as permanent conduction defects requiring permanent pacemaker or may have temporary conduction abnormalities requiring temporary pacemaker or supportive care. We present the case of a young woman who suffered from BCT after being kicked by a horse with the development of a significant substernal hematoma. She developed temporary atrioventricular block, which was completely resolved with the decrease in the size of the substernal hematoma suffered.

Previous studies analyzing ghrelin and obestatin expression in thyroid gland tissue are not unanimous and are mostly related to ghrelin. The role of ghrelin and obestatin in the thyroid gland appears very interesting due to their probable involvement in cell proliferation. Furthermore, since the thyroid gland is associated with the maintenance of energy balance, the relationship between ghrelin, obestatin and thyroid function is worthy of consideration. The aim of the study was to assess ghrelin and obestatin immunocytochemical expression in nodular goiter (NG), papillary cancer (PTC) and medullary cancer (MTC). Analyzed samples included 9 cases of NG, 8 cases of PTC and 11 cases of MTC. The analysis of ghrelin and obestatin expression was performed by use of the immunohistochemical (IHC) EnVision system and evaluated with filter HSV software (quantitative morphometric analysis). Quantitative ghrelin expression in MTC cells was higher than in NG (p = 0.013) and correlated negatively with the size of the tumor (r= -0.829, p thyroid cell proliferation. The differences between ghrelin and obestatin immunoreactivity in benign and malignant thyroid tumors could support the theory of alternative transcription of the preproghrelin gene and independent production of ghrelin and obestatin.

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

Hashimoto thyroiditis (HT) and other benign goiters (BG) might influence patients' quality of life (QoL). The objective of this study was to analyze influence of surgery on these patients' QoL. A prospective cohort study was conducted. The ThyPRO questionnaire was used in the QoL assessment. The HT patients experienced significantly worse hypothyroid symptoms and sex life than the BG patients. The improvement in QoL in the BG patients was significant after surgery in all ThyPRO domains. In the HT patients, the improvement was significant in all but two domains, eye symptoms and cognitive impairment. The best improvement in both groups was in overall QoL. None of the patients developed permanent consequences. The QoL of HT and BG patients is impaired and improves significantly after surgical treatment. Thyroidectomy should be considered as a treatment option in the HT patients more often as in the BG patients. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

Percutaneous laser thermal ablation (LTA) has been applied in several tumors. In this study we evaluated the safety and long-term efficacy of LTA in the treatment of benign thyroid nodules. Seven patients with autonomous hyperfunctioning thyroid nodule (group A) and five patients with compressive nodular goiter (group B) were treated with LTA. Up to three needles were positioned centrally in the thyroid nodule and laser fiber was placed in the lumen of the needle. Laser illumination was performed reaching a maximal energy deposition of 1800 J per fiber. Thyroid nodule volume, endocrinologic, and clinical evaluation were performed at baseline, 3, and 12 months after the treatment. Scintigraphy was performed at diagnosis and 12 months after the first session in group A. In group A, mean thyroid volume decreased from 3.15 +/- 1.26 mL to 0.83 +/- 0.49 mL (p thyroid volume decreased from 11.14 +/- 4.99 mL to 3.73 +/- 1.47 mL (p thyroid nodules.

The aim of this study was to evaluate the potential advantages and the general operative cost of the Harmonic Scalpel (HS) in surgery for multinodular goiter (MNG). Patients undergoing total thyroidectomy (TT) for MNG were prospectively allocated in a conventional tie-and-clip (TC) group (n = 50) and an HS group (n = 50). All pre- and postoperative data were recorded. The economic evaluation was based on a microcost measurement and aimed to consider all the resources consumed for each patient during the surgical procedure. To compare the results, we used the nonparametric unpaired two-tailed Mann-Whitney test. There were 81 women and 19 men (mean age, 55 +/- 15 years). Mean preoperative TSH level was 1.2 (SD, 1.1) (TC) and 1.3 (SD, 2) (HS) (P = NS). Mean body mass index was 24.72 (SD, 8) (TC) and 25.6 (SD, 8) (HS) (P = NS). Four patients experienced a transient hypocalcemia (2 in each group). One patient had a postoperative hematoma requiring surgical evacuation (HS). One patient experienced a transient recurrent nerve palsy (TC). Mean length of surgery was 104 (SD, 32) (TC) and 84 minutes (SD, 17) (HS) (P = .0001). Mean length of hospitalization was 2 days in both groups (SD, 1) (P = NS). Mean operative cost per patient was 990 euro (SD, 191) in the TC group and 1,024 euro (SD, 143) in the HS group (P = NS). Safety and efficiency of the HS is comparable to the tie-and-clip technique in thyroid surgery. The use of the HS in MNG surgery allows for a significant reduction in the length of the procedure with a comparable cost.

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

Serum thyroid hormone and TSH concentrations were monitored in a patient with multinodular endemic goiter and severe methimazole (MMI) induced hypothyrodism up to 190 days after drug withdrawal. Serum concentrations of TT3, TT4 and TSH returned to normal values at the 6th., the 140th, and the 120th. day respectively. Within the first 20 days after MMI withdrawal the increase of serum T3 levels was correlated with the observed decrease of serum TSH concentrations. Successively T3 values decreased and T4 levels progressively increased. Six months after MMI withdrawal basal serum TSH concentration was normal while an exaggerated response to TRH was observed. We think that this peculiar hormone pattern is due to iodine depletion. In this case TSH hyperstimulation increases predominantly T3 secretion demonstrating the reduced thyroidal ability to produce T4 when hyperstimulated.

Full Text Available The dynamics of structural and functional state of thyroid gland was studied, as well as the levels of antithyroid antibodies in patients with diffuse toxic goiter (DTG during long-term treatment with thyrostatic agents. Objective of the study — to perform the analysis of changes in the levels of thyrotropin receptor antibodies (TRAbs, antibodies to thyreoproxidase (ATPO at DTG manifestation and during long-term drug therapy, as well as to determine TRAbs levels in relapsing course of disease. Materials and methods. 112 patients with DTG were examined. The duration of the disease at the examination beginning was from 1 month to 15 years. All patients were divided into two groups depending on the DTG duration: the first group consisted of 46 patients with disease duration up to 1 year (3.96 months in average, the second one consisted of 66 patients with disease duration more than 1 year (3.32 years in average. This distribution was specified by desire to study the dynamics of antithyroid antibody levels at disease manifestation and during long-term course of autoimmune process. Results. On the background of thyrostatic therapy, the number of patients with focal thyroid gland formations increased. When analyzing the levels of antithyroid antibodies at baseline, it was revealed that ATPO level in both groups of patients with DTG significantly exceeded the performance of the control group (group1 — 283.33 ± 86.61 U/ml vs 35.65 ± 4.90 U/ml; group 2 — 207.34 ± 42.52 U/ml vs 35.65 ± ± 4.90 U/ml and did not depend on disease duration and preliminary treatment duration. In 6 months of treatment, the level of ATPO in both groups was not decreased. The study of TRAbs dynamics during thyrostatic therapy revealed that in patients of the first and second groups, the decrease of TRAbs level was noted only 6–12 months after the start of thyrostatic therapy (group 1 — from 17.19 ± 2.17 IU/l to 6.95 ± 2.39 IU/l, p < 0.05; group 2 — from 14

We determined the CT density of the thyroid gland in 60 patients with normal thyroids and 176 patients with various thyroid disorders. The density was 75+-6.2 H.U. in normal thyroids, which was markedly higher than in goiters (66+-6.0 H.U.), while there was a considerable further decrease in patients with immunogenic hyperthyrodism, the density being 48.5+-7.9 H.U. The thyroids of patients with nonimmunogenic hyperthyroidism differed from these by virtue of a significantly greater density, 79.8+-12.5 H.U. The clinical importance of CT investigation of the thyroid is its ability to distinguish rapidly between immunogenic hyperthyroidism without ocular symptoms and the (mostly iodine induced) nonimmunogenic form. There is a linear correlation between CT density and iodine concentration in the thyroid tissue; this was determined in surgical specimens from 17 patients. Iodine concentration in the thyroid, as well as the iodine content of the whole gland, can thus be calculated from the measured CT density at any time by estimating the volume of the gland with ultrasound and combining this value with the measured iodine concentration. The results correlate well with those found using the X-ray fluorescence method.

Hyperthyroidism may be defined as those clinical conditions which result from an increase in the circulating levels of one or both thyroid hormones. Hyperthyroidism in broad sense could be classified with toxic diffuse goiter, toxic adenomatous goiter, and toxic multinodular goiter on the basis of the circulating thyroid hormone levels. For this study, the subject included 94 cases with hyperthyroidism were presented in 77 with toxic diffuse goiter, 8 with toxic adenomatous goiter, and 9 with toxic multinodular goiter on the levels of 125 IT 3 resin uptake rate and serum thyroxine (T 4 ). The observed results were as follows: 1) In the cases of hyperthyroidism including toxic diffuse goiter, toxic adenomatous goiter, and toxic multinodular goiter, 20.21% of the patients were male and 79.79% female. The majority of the patients were in 2nd to 4th decades of their lives. 2) There were objective signs clearly manifested in hyperthyroidism including toxic diffuse goiter and toxic adenomatous goiter which were rare in the multinodular goiter. The clinical signs in toxic diffuse and toxic adenomatous goiter included wide pulse pressure, tachycardia, systolic murmur, exophthalmos, tremor and warm skin etc. 3) The most frequent complaints of the patients with hyperthyroidism were palpitation, weight loss, increased appetite, perspiration, heat intolerance, nervousness, exertional dyspnea, and menstrual disturbance etc. There was no clear difference in the incidence of symptoms between toxic diffuse goiter and toxic adenomatous goiter, but there was clear difference between toxic multinodular goiter. 4) Considering of results of 125 IT 3 resin uptake rate and serum T 4 level in toxic diffuse goiter, toxic adenomatous goiter and toxic multinodular goiter, 125 IT 3 resin uptake rate was 49.15±9.94% (mean) and serum T 4 21.29±7.04 ug/dl (mean) in toxic diffuse goiter. In toxic multinodular goiter, 125 I T 3 resin uptake rate was 32.47±6.74% (mean) and serum T 4 level 11.03�

Radioactive iodine 131 ( 131 I) is used for the treatment of hyperthyroidism at Hospital San Juan de Dios. The most common causes of hyperthyroidism have been Graves disease or diffuse goiter, toxic multinodular goiter and toxic nodular goiter, among others; but, the results are unknown and factors that have influenced the treatment with 131 I. The study has included only patients with these causes, and have been administered radioactive iodine 131 as treatment. 180 cases have been treated with radioactive iodine, 75.0% have presented diffuse goiter, 22.2% multinodular goiter and 2.8% nodular goiter, where were been 144 female patients (80%) and 36 male patients (20%). Women have had predominance in the three groups that were analyzed pathologies, according to medical literature, an approximate incidence of 0.4 cases has existed per thousand women to year. A proportional relationship between clinical size of goiter and failure of therapy with 131 I has been in diffuse goiter for the handling of hyperthyroidism. Likewise, male sex has been risk factor in the failure of such therapy. Multinodular goiter and nodular goiter have not had difference between the results according to sex and size of goiter. Most hyperthyroid patients with diffuse goiter, nodular and multinodular have received 131 I as treatment, and previously this, they have received propylthiouracil; treatment outcome was unaffected. Treatment with 131 I in hyperthyroid patients has managed to be effective for reduction in size of the thyroid gland in diffuse goiter, nodular goiter and multinodular [es

We conclude that growth-promoting IgGs lacking ability to stimulate cAMP production may play a role in the large multinodular goiters due to chronic iodine deficiency.

Full Text Available Background. Information about iodine intake is crucial for preventing thyroid diseases. Inadequate iodine intake can lead to thyroid diseases, including nontoxic nodular goiter (NNG. Objective. To estimate iodine intake and explore its correlation with thyroid diseases among Israeli adults living near the Mediterranean coast, where iodine-depleted desalinated water has become a major source of drinking water. Methods. Cross-sectional study of patients attending Barzilai Medical Center Ashkelon. Participants, who were classified as either NNG (n=17, hypothyroidism (n=14, or control (n=31, provided serum thyroglobulin (Tg and completed a semiquantitative iodine food frequency questionnaire. Results. Elevated serum Tg values (Tg > 60 ng/mL were significantly more prevalent in the NNG group than in the other groups (29% versus 7% and 0% for hypothyroidism and controls, resp., P<0.05. Mean estimated iodine intake was significantly lower in the NNG group (65±30 μg/d than in controls (115±60 μg/d (P<0.05 with intermediate intake in the hypothyroid group (73±38 μg/d. Conclusions. Elevated serum Tg values and low dietary iodine intake are associated with NNG among adult patients in Ashkelon District, Israel. Larger studies are needed in order to expand on these important initial findings.

Radioiodine ( 131 I) therapy is the definitive treatment of toxic multinodular goiter (TMNG). Treatment failure may result in relapse after 131 I therapy. The present study was undertaken to reduce treatment failure rate of 131 I therapy in TMNG patients. Multiple causes may have lead to treatment failure of 131 I in TMNG patients making it difficult to establish a direct cause-effect relationship and take corrective action. Therefore, the JURAN methodology of quality improvement was applied. The treatment failure rate in 80 TMNG patients treated with 131 I in the period 2003-06 was 29%. The root cause analysis identified delay in decision to radioablate and concomitant antithyroid drugs (ATD) with 131 I therapy as factors leading to relapse. In 2007, a change in management was introduced with decision to radioablate all TMNG patients not remitting at 1 year of ATD and to withdraw ATD for 2 weeks prior to 131 I therapy. A total of 63 patients of TMNG followed the changed protocol between 2007 and 2009. Further analysis showed that one of the factors identified in the initial brainstorming (high iodide pool in the patient) had not been addressed in the protocol currently followed. The protocol was modified to include patient preparation and implemented after standardization. The post- 131 I relapse rate in patients treated after implementation of the new protocol from 2007 to 2009 was 18% which further reduced to 16% in 2011 after modification of the protocol. The failure rate of 131 I therapy in TMNG reduced from 29% to 16% through standardization of the treatment procedure achieved by the use of Juran Methodology that helped to identify process-related defects.

Although the prevalence of MNG is widespread throughout the world, its pathogenesis is poorly understood, and the complex interactions of both genetic predisposition and the individuals' environment are likely. However, to the best of our knowledge, it remains unknown whether there is a relationship between vitamin D status and prevalence or pathogenesis of euthyroid MNG. Therefore, the goal of the present study was determination of vitamin D status in euthyroid MNG as well as exploration of the correlation between vitamin D status & TSH levels. A total of 77 patients diagnosed with euthyroid MNG and 50 subjects without goiter were matched according to age, weight and BMI as control group in this case control study. We found that patients with euthyroid MNG had statistically significant lower mean of [25(OH)D] (24.21±8.68ng/mL) in comparison with its mean in control subjects (28.37±10.91ng/mL, P value=0.019). The 28 sufficient vitamin D MNG patients had statistically significant lower level of TSH than 49 insufficient vitamin D MNG patients. Vitamin D and TSH levels correlate with vitamin D levels in MNG patients in Pearson correlation. Also 25 OH vitamin D was a significant independent predictor for TSH levels among euthyroid MNG patients in regression analysis. Patients with euthyroid MNG have lower levels of vitamin D and TSH levels correlate with vitamin D levels in euthyroid MNG patients. In addition, 25 OH vitamin D was a significant independent predictor for TSH levels among euthyroid MNG patients. We recommend hypovitaminosis D evaluation and correction in patients with MNG.

The reduction was comparable in groups A and B (23.1 ± 8.8 and 23.3 ± 16.5%, respectively; P = 0.95). In group C......, the reduction (32.9 ± 20.7%) was more pronounced than in groups A (P = 0.03) and B. The smallest cross-sectional area of the trachea increased in all groups: 3.8 ± 2.9% in A, 4.8 ± 3.3% in B, and 10.2 ± 33.2% in C, with no significant difference among the groups. Goiter-related symptoms were effectively reduced...... and there were no major safety concerns. Conclusion: In this dose-selection study, 0.03 mg MRrhTSH was the most efficacious dose as an adjuvant to (131)I therapy of MG. It was well tolerated and significantly augmented the effect of (131)I therapy in the short term. Larger studies with long-term follow...

Recombinant human thyrotropin (rhTSH) reduces the activity of radioiodine required to treat multinodular goiter (MNG), but acute airway compression can be a life-threatening complication. In this prospective, randomized, double-blind, placebo-controlled study, we assessed the efficacy and safety (including airway compression) of different doses of rhTSH associated with a fixed activity of {sup 131}I for treating MNG. Euthyroid patients with MNG (69.3 +- 62.0 mL, 20 females, 2 males, 64 +- 7 years) received 0.1 mg (group I, N = 8) or 0.01 mg (group II, N = 6) rhTSH or placebo (group III, N = 8), 24 h before 1.11 GBq {sup 131}I. Radioactive iodine uptake was determined at baseline and 24 h after rhTSH and thyroid volume (TV, baseline and 6 and 12 months after treatment) and tracheal cross-sectional area (TCA, baseline and 2, 7, 180, and 360 days after rhTSH) were determined by magnetic resonance; antithyroid antibodies and thyroid hormones were determined at frequent intervals. After 6 months, TV decreased significantly in groups I (28.5 +- 17.6%) and II (21.6 +- 17.8%), but not in group III (2.7 +- 15.3%). After 12 months, TV decreased significantly in groups I (36.7 +- 18.1%) and II (37.4 +- 27.1%), but not in group III (19.0 +- 24.3%). No significant changes in TCA were observed. T3 and free T4 increased transiently during the first month. After 12 months, 7 patients were hypothyroid (N 3 in group I and N = 2 in groups II and III). rhTSH plus a 1.11-GBq fixed {sup 131}I activity did not cause acute or chronic changes in TCA.

Full Text Available We studied the presence of antithyroid antibodies in subjects with slight to overt thyroid disfunction. Fifty nine subjects that showed goiter or TSH levels above 5.0 mU/L were included. The percentage of patients with positive anti Thyroid Peroxidase antibodies (anti TPO was 18.63%. From them, 90.9% exhibited goiter along with thyroid dysfunction, whereas only 9.1 % had goiter without thyroid disfunction. There was no patient without goiter that showed anti TPO levels above 100 mUl/ mL.We conclude that thyroid autoimmune disease is very prevalent among our patients, so it must be suspected in subjects with or without goiter, as well as in those with slight thyroid disfunction, because it could progress to overt hypothyroidism.

Recombinant human thyroid-stimulating hormone (rhTSH) enhances {sup 131}I uptake, permitting a decrease in radiation for the treatment of multinodular goiter (MNG). Our objective was to evaluate the safety and efficacy of a single 0.1-mg dose of rhTSH, followed by 30 mCi {sup 131}I, in patients with MNG. Seventeen patients (15 females, 59.0 {+-} 13.1 years), who had never been submitted to {sup 131}I therapy, received a single 0.1-mg injection of rhTSH followed by 30 mCi {sup 131}I on the next day. Mean basal thyroid volume measured by computed tomography was 106.1 {+-} 64.4 mL. {sup 131}I 24-h uptake, TSH, free-T4, T3, thyroglobulin, anti-thyroid antibodies, and thyroid volume were evaluated at regular intervals of 12 months. Mean {sup 131}I 24-h uptake increased from 18.1 {+-} 9.7 to 49.6 {+-} 13.4% (P < 0.001), a median 2.6-fold increase (1.2 to 9.2). Peak hormonal levels were 10.86 {+-} 5.44 mU/L for TSH (a median 15.5-fold increase), 1.80 {+-} 0.48 ng/dL for free-T4, 204.61 {+-} 58.37 ng/dL for T3, and a median of 557.0 ng/mL for thyroglobulin. The adverse effects observed were hyperthyroidism (17.6%), painful thyroiditis (29.4%) and hypothyroidism (52.9%). Thyroid volume was reduced by 34.3 {+-} 14.3% after 6 months (P < 0.001) and by 46.0 {+-} 14.6% after 1 year (P < 0.001). Treatment of MNG with a single 0.1-mg dose of rhTSH, followed by a fixed amount of radioactivity of {sup 131}I, leads to an efficacious decrease in thyroid volume for the majority of the patients, with a moderate incidence of non-serious and readily treatable adverse effects.

Full Text Available Objective: Geriatric patient population has special importance due to particular challenges. In addition to the increase in incidence of toxic nodular goiter (TNG with age, it has a high incidence in the regions of low-medium iodine intake such as in our country. The aim of this study was to evaluate the overall outcome of high fixed dose radioiodine (RAI therapy, and investigate the particular differences in the geriatric patient population. Methods: One hundred and three TNG patients treated with high dose I-131 (370-740 MBq were retrospectively reviewed. The baseline characteristics; age, gender, scintigraphic patterns and thyroid function tests before and after treatment, as well as follow-up, duration of antithyroid drug (ATD medication and achievement of euthyroid or hypothyroid state were evaluated. The patient population was divided into two groups as those=>65 years and those who were younger, in order to assess the effect of age. Results: Treatment success was 90% with single dose RAI therapy. Hyperthyroidism was treated in 7±7, 2 months after RAI administration. At the end of the first year, overall hypothyroidism rate was 30% and euthyroid state was achieved in 70% of patients. Age was found to be the only statistically significant variable effecting outcome. A higher ratio of euthyroidism was achieved in the geriatric patient population. Conclusion: High fixed dose I-131 treatment should be preferred in geriatric TNG patients in order to treat persistent hyperthyroidism rapidly. The result of this study suggests that high fixed dose RAI therapy is a successful modality in treating TNG, and high rates of euthyroidism can be achieved in geriatric patients.

Factors affecting sustainable iodine deficiency elimination in Pakistan: A global perspective

Full Text Available Iodine deficiency remains a considerable challenge worldwide, even after decades of efforts to address the problem. The aim of this review is to present the current situation in historically iodine-deficient Pakistan regarding iodine nutritional status and place it in a global perspective. We collected relevant articles from online bibliographic databases and websites of concerned organizations that addressed prevalence of goiter/iodine deficiency and barriers to sustainable control. We divided the studies into pre- and post-1994, a landmark year when Pakistan formally adopted the universal salt iodization (USI programme. Overall, 56 studies reported goiter/iodine deficiency prevalence in Pakistan. Before 1994, six studies (30% reported a goiter prevalence ≥70%, while nine studies (45% reported a goiter prevalence between 30% and 70%. Only five studies (25% found a goiter prevalence less than 30%, of which only two studies reported prevalence <10%. From 1994 onwards, 15 studies (41.7% reported a goiter/iodine deficiency (ID prevalence ≥50%, of which seven studies reported prevalence ≥70%, while three studies (8.3% found a goiter prevalence of 30%–49%, nine studies (25% found a goiter prevalence of 10%–29%, and five studies (13.9% reported prevalence of <10%. Four studies (11.1% reported lower goiter prevalence but higher prevalence of iodine deficiency. The efforts in the past two decades resulted in up to a 50% decline in iodine deficiency disorders (IDD. Variable remaining factors and the recent results, however, indicate that this decline may be non-uniform and even over-estimated. Coordinated and regionally adopted efforts for eradication of IDD from all stakeholders should be pursued. Policy makers should take steps to protect future generations and alert concerned organizations about the importance of careful assessments and estimates of iodine nutritional status.

Dysphagia is an impairment of swallowing that may involve any structures from the mouth to the stomach. Esophageal dysphagia presents with the sensation of food sticking, pain with swallowing, substernal pressure, or chronic heartburn. There are many causes of esophageal dysphagia, such as motility disorders and mechanical and inflammatory diseases. Infrequently dysphagia arises from extrinsic compression of the esophagus from any vascular anomaly of the aortic arch. The most common embryolog...

Radioactive iodine (RAI), principally 131 I, effectively controls hyperthyroidism in the majority of patients. The subsequent development of hypothyroidism, however, has been of increasing concern since it was first pointed out by Chapman and Maloof in 1955. And the steady increase of late hypothyroidism during the passage of time was known with its relation with dosage of RAI. The authors have investigated the development of hypothyroidism in 935 patients with diffuse toxic goiter (DTG) who were treated with RAI ( 131 I) at the Seoul National University Hospital from 1960 to 1977 to reveal its relation with the number of RAI treatments, dosage of RAI, age of patients and exophthalmos with the following results. 1) The incidence of hypothyroidism by year after RAI therapy among 631 patients with DTG who were treated with single RAI regimen was 7.4% (1 year), 11.8% (2 year), 16.2% (3 year), 22.1% (4 year) and 25.5% (5 year), and that among 163 patients given multiple RAI treatments was 8.6% (1 year), 10.4% (2 year), 13.3% (3 year), 29.1% (4 year), and 54.1% (5 year) respectively showing much higher yearly increments from 4 years after RAI treatment in comparison with the former. 2) Among 550 patients in the lower dose group treated with single RAI regimen less than 5.0 mCi (Mean±S.D.: 4.3±0.6 mCi), the incidence of hypothyroidism by year after RAI treatment was 6.8% (1 year), 11.4% (2 year), 15.4% (3 year), while among 81 patients in the higher dose group given single RAI treatment not less than 5.5 mCi (Mean±S.D.: 6.3±0.5 mCi) it was 12.0% (1 year), 15.4% (2 year) and 20.4% (3 year) respectively. However, the duration till euthyroid state after RAI therapy in the two groups was 5.1±3.6 months and 4.8±2.8 months respectively showing no statistically significant difference (p>0.1). 4) The incidence of hypothyroidism after RAI treatment in patients younger than 30 years of age was 4.3% (1 year) and 7.7% (2 year); in patients from 30 years to 49 years of age, 5

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.

Amyloid goitre is at an extremely rare occurrence. Authors review the origin of disease and its symptoms, diagnostic and therapeutic tools. The disease may be due to either primary or secondary systemic or local amyloidosis. Diagnosis may be made even before surgery on anamnestic data, on very rapid growth of thyroid glands, on diffuse appearance, on other symptoms of systemic amyloidosis, on findings of iconographic procedures and on detection of amyloid in aspirates. Final diagnosis is based on histology. Surgical therapy is aiming at avoidance of the existing and the threatening consequences of expanding mass. The outcome is independent from thyroid surgery, it is related to other manifestations of amyloidosis. Concerning with the present case the chronic superior vena cava syndrome and chylous pleural effusion as first described symptoms and asymptomatic hyperthyroxinaemia is emphasised. Neither other organ involvement, nor primary amyloidogenous molecula was found during the 18 months follow up, so patient has secondary and localised amyloidosis.

The twenty-second screening for thyroid disorders in radiation-contaminated areas of the Ukraine

One hundred and ninety-one people who reside in radiation-contaminated areas of the Ukraine near the site of the Chernobyl nuclear plant accident were screened in 1999. The ages of people screened ranged from 1 to 74 years. Diffuse goiter was palpable in 67.5%, and nodular goiter in 3.1%. Thyroid cancer was detected in only one suspicious case. Among the people with diffuse goiter, however, there were positive anti-thyroglobulin hemagglutination tests (TGHA) in 6.7% and positive anti-microsome hemagglutination tests (MCHA) in 16.7% of cases. In addition, urinary iodine concentrations and daily urinary excretion were low. Thus, it is thought that the majority of diffuse goiters in this area are not due to autoimmune thyroiditis but to iodine deficiency. At present, no definite conclusion can be drawn on the relationship between the large number of diffuse goiters and radioactive contamination. Further studies are required. (author)

Intrathoracic toxic thyroid nodule causing hyperthyroidism with a multinodular normal functional cervical thyroid gland

Serim, Burcu Dirlik; Korkmaz, Ulku; Can, Unal; Altun, Gulay Durmus

2016-01-01

Radionuclide scintigraphy with I-131 and Tc-99m pertechnetate ( 99 mTc0 4 ) has been widely used in detecting toxic nodules. Intrathoracic goiter usually presents as an anterior mediastinal mass. Mostly the connection between intrathoracic mass and the cervical thyroid gland is clearly and easily identified occurring as a result of inferior extension of thyroid tissue in the neck, which is called as secondary intrathoracic goiter. Completely separated, aberrant or in other words primary intrathoracic goiters arise as a result of abnormal embryologic migration of ectopic thyroid closely associated with aortic sac and descend into the mediastinum. Intrathoracic goiters are generally nontoxic nodules existing with mass effect without causing hyperthyroidism. However, mostly reported cases had enlarged thyroid glands in the neck. This report demonstrates the usefulness of I-131 and 99 mTc0 4 scintigraphy for detecting intrathoracic goiter causing hyperthyroidism with a normal functioned cervical thyroid gland

First results with a radioreceptor-assay (TRAK-Assay) for TSH-receptor-autoantibodies

1983-01-01

A new radioreceptor-assay (TRAK-assay) for autoantibodies against TSH-receptors was tested in 48 untreated thyrotoxic patients (26 regional autonomies, 22 toxic diffuse goiters). None of the 26 patients with regional autonomy showed positive autoantibody-titers. 4 patients with toxic diffuse goiter and thyrotoxic exophthalmos were TRAK-positive. Positive titers of microsomal and thyreoglobulin autoantibodies could be seen in 8 of 9 patients with positive TRAK-titers. In accordance with the conventional methods for detecting thyroid-stimulating immunoglobulins the new TRAK-assay seems to be suited for differentiating between immunogenic toxic diffuse goiter (Graves' disease) and goiter with disseminated autonomy as well as for prediction of relapse.

This research was designed with cross sectional study with purposive method.  This research was conducted at Kabupaten Tasikmalaya, West Java from April to May 2005. The respon­dent consisted of 60 elementary school students, which 30 of them classified as normal group and the rest of them belong to the goiter group. The two sample groups were analyzing by the t-test and Mann Whitney test. The correlation variables were analyzed by the Spearman test. There were significant difference between the income on the normal group and the goiter group; the normal group had higher income than the rest. There were significant difference between the adequacy level of energy on the normal group (73.5% and the goiter group (55.8% and the average of the variety of goitrogenic food consumption. The Mann Whitney test showed there were also significant differences for the quality of salt. There were significant correlations between mother knowledge about IDD with the adequacy of iodium, and between the cases of goiter with the quality of salt consumed by the family. Intensive nutrition education of IDD is needed to improve the nutrition knowledge of the mothers, as well as the availability of the accessible iodized salt.

Full Text Available Introduction: South Asian population has a particularly high prevalence of thyroid disorders mainly due to iodine deficiency and goitrogen use. There is no data available for prevalence of thyroid disorders in the general population living in nonmountainous regions of Pakistan. Materials and Methods: A total of 2335 residents of Pak Pattan, Punjab, Pakistan were interviewed about demographic, dietary, medical and environmental history as well as screened for goiter. Individuals of all ages and either gender were included. Results: Median age was 34 (10-88 years and 1164 (49.9% were males. Median monthly income was 49 (3.9-137 USD. Six hundred and sixty-nine (28.7% subjects had palpable goiter. 77.5% (n = 462 and 22.5% (n = 133 had World Health Organization Grade I and Grade II goiters respectively, further screened by measuring thyroid-stimulating hormone (TSH. In subjects with TSH <0.4 mg/dL, free T3 and free T4 levels were measured. In 185 goiter subjects when TSH was measured, 50% (n = 93 were euthyroid, 48% (n = 89 were hyperthyroid, and one subject each was hypothyroid and subclinically hyperthyroid. 29/89 hyperthyroid subjects underwent radionuclide scanning. Twelve subjects had heterogeneous uptake consistent with multinodular goiter, 12 subjects had diffuse uptake, two had cold nodules and two had hyperfunctioning single nodules. Goiter was significantly more common among females, unmarried individuals and individuals drinking tube well (subterranean water. Goiter was less common among those who consumed daily milk, daily ghee (hydrogenated oil, spices, chilies, and turmeric. Discussion: In our study population, goiter was endemic with very high prevalence of hyperthyroidism. Turmeric use was association with reduced goitrogenesis. Further studies to assess iodine sufficiency, thiocyanate exposure and autoimmunity need to be conducted. Masses consuming high goitrogen diets should be educated to incorporate turmeric, spices and green

Full Text Available Background: The course of pregnancy and delivery in patients with diffuse toxic goiter (DTG is often complicated by preeclampsia, fetoplacental insufficiency, placental abruption and associated with higher maternal and perinatal mortality. Aim: To study particulars of fetoplacental complex functioning in DTG. Materials and methods: We assessed pregnant patients with DTG (n = 92 and their newborns (n = 94. By the time of delivery, 86 of patients were clinically and biochemically euthyroid. Functions of fetoplacental complex (by levels of placental lactogen, α-fetoprotein, estriol, progesterone and cortisol were assessed by radioimmune and immunoenzyme assays. Fetometrical parameters of fetuses were studied by ultrasound method. Complex assessment of placentas was done by light and electronic microscopy. Results: Eighty seven (94,6% patients with DTG had combined complications of pregnancy. The most frequent were: the threat of termination of pregnancy, in 68 (73.9% of cases, low placenta placement, in 23 (25%, anemia, in 56 (60.9%, pre-eclampsia, in 56 (60.9%. In 59 of patients (64.1%, fetoplacental insufficiency was diagnosed, with predominance of strain or exhaustion reactions. Critical status of fetoplacental complex was found in pregnant patients with uncontrolled DTG and duration of control of less than 20 weeks, as well as in pregnant patients with DTG relapses. The values of main hormones (placental lactogen, α-fetoprotein and progesterone were below 10th percentile.According to the results of the ultrasound assessments, fetuses from mothers with DTG during gestation demonstrated decrease of the majority or percentile parameters, such as biparietal cranial size, fetal femoral length, abdomen diameter, that was especially prominent in the groups with relapsing DTG.Eighty eight of 94 newborns (93.6% were born full-term.

Full Text Available ABSTRACT Background: Pesticides are toxic material  or a substance or mixture of substances used to kill a pest or  intended for preventing, destroying, repelling or mitigating any pest.[2] A pesticide may be a chemical substance, biological agent (such as a virus or bacterium, antimicrobial, disinfectant or device used against any pest. Pests in agriculture  include insects, plant pathogens, weeds, molluscs, birds, mammals, fish, nematodes (roundworms.  Although there are benefits to the use of pesticides, there are also drawbacks, such as potential toxicity to humans and environment. Usage pesticide which do not well  managed  may  generate negative impact. Chronic poisoning of pesticides may produce adverse effect on health, including, cancer, genetic mutation, thyroid diasease, reproductive disorders and neurodegenerative disases. Preliminary researh showed that farmer in district of Ngablak   98 %  have experience of pesticide exposure. Result of study indicate that 16,5 % farmer of horticulture that have pesticide exposure  district of Ngablak  have a disorder of  thyroid and manifest as goiter. This research objective was to find out the relation between pesticides exposure and the incidence of goitre on farmer exposed to pesticides. Method: this research used a case control design with  68 case and 68 control. The variable of the research include age, education, work duration, time of activity per day, pesticide type, pesticide dose, spraying frequency, time of  spraying, farmer position to wind direction while spraying and using of personal protective equipment. Result: Research result indicated  that variables that related to the incidence of endemic goitre were age (OR = 3,83; CI 95%= 1,88 – 7,81, work duration (OR = 12, 79; CI 95% = 2,85 – 57,53, time of activity per day (OR = 2,47; CI 95% = 1,16 – 5,23, pesticide type (OR = 5,86; CI 95% = 2,73 – 12,56, pesticide dose (OR = 2,96; CI 95% = 1,37 – 6

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

Esophageal rupture may occur from an external force such as an explosion or trauma to the chest, spontaneously as from vomiting, by instrumental perforations during endoscopy, or by foreign bodies. A case of Boerhaave syndrome was seen in a healthy 52 years old man who complained of substernal pain, vomiting and dyspnea after over-drinking. Abnormalities seen on the chest film were; A) hydropneumothorax B) mediastinal emphysema and C) subcutaneous emphysema. These characteristic roentgen findings were confirmed an esophageal rupture.

To assess the effectiveness of radioactive iodine (RAI) therapy and the incidence of hypothyroidism post RAI in patients with subclinical hyperthyroidism or clinical hyperthyroidism with Multinodular Goiter (MNG). A retrospective study of 69 consecutive patients treated with (131)I for MNG during the year 2008 observed for six months. All patients received a single fixed dose of 16 mCi (592 MBq) weighted by the gland size. They were categorized into two groups: subclinical hyperthyroidism or clinical hyperthyroidism. We compared the success rate and the incidence of hypothyroidism. The thyroid dysfunction was corrected in 82.09% of the patients. Success rate was 100% in the clinical hyperthyroidism group and 78.13% in the subclinical hyperthyroidism group (P=0.105). The overall incidence of hypothyroidism was 16.42%; 25.00% of patients with clinical hyperthyroidism and 14.55% with subclinical hyperthyroidism developed this secondary effect (P=0.400). No statistically significant differences were found in the success rate in the incidence of hypothyroidism when the results were analyzed according to the thyrotropin decrease in patients with subclinical hyperthyroidism. Seven patients had positive anti-thyroid peroxidase antibodies (anti-TPO) before therapy. The incidence of hypothyroidism was significantly higher in them (57.14% vs 11.67%; P=0.011). Cardiac arrhythmias were four times more frequent in patients with clinical hyperthyroidism. Previous treatment with thiamazol positively affected the outcome. A single fixed weighted dose of (131)I is highly effective and safe for the control of clinical and subclinical hyperthyroidism due to MNG. Patients with anti-TPO antibodies may have a high risk of developing post-iodine hypothyroidism. Copyright © 2010 Elsevier España, S.L. y SEMNIM. All rights reserved.

We have investigated the thyroid uptake of Tl-201 in 37 patients with various types of goiter, and in six with normal thyroids. Significant thallium uptake was found in all cases in which there was thyroid enlargement, including Graves' disease, toxic thyroid nodule, primary hypothyroidism, simple goiter, Hashimoto's disease, thyroid carcinoma, and thyroid adenoma. If goiter was absent, however, there was no demonstrable uptake - e.g., in secondary hypothyroidism, subacute thyroiditis, and the normal controls. Thallium uptake did not correlate with thyroid function tests such as BMR, T 3 -RU, T 3 , T 4 , TSH, antithyroid antibodies, or the 24-hr I-131 uptake. In 23 patients with diffuse goiter, on the other hand, maximum Tl-201 uptake correlated well with thyroid weight: r = 0.836 (p < 0.001); y = 0.02 x + 0.06

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

Full Text Available Objective: Thyroid cancer can be associated with thyrotoxicosis caused by Graves' disease, toxic multinodular goiter, or toxic nodular goiter. The aim of this study was considered to be endemic in our region have received the diagnosis of hyperthyroidism, thyroid cancer is detected thyroidectomy performed and patients were retrospectively evaluate. Methods: We retrospectively studied 69 patients assessed for hyperthyroidism between 2006 and 2012. Clinical hyperthyroidism was diagnosed by elevated tri-iodothyronine/thyroxine (T3/T4 ratios and low thyroid-stimulating hormone (TSH levels, with clinical signs and symptoms. The criteria for surgery were cytological evidence of malignancy, a goiter causing symptoms of tracheal or esophageal compression, side effects of antithyroid drug therapy, or Graves’ disease with multiple relapses after therapy withdrawal or responsiveness to antithyroid drugs. Results: Totally 69 patients were included. In 20 (28.9% patients there was toxic multinodular goiter, in 28 (40.6% Graves’s disease, and in 21 (30.5% patients there was toxic nodular goiter. Of these patients, 12 (17.4% had thyroid cancer. Conclusions: As a result; low likelihood of malignancy in patients with hyperthyroidism, though suspicious lesions detected in the lymph nodes and neck adenopathies be examined in detail.

A specific, sensitive, and reproducible in vitro assay for antithyroid compounds and environmental goitrogens has been used to investigate antithyroid activity (AA) in small samples of water supplying 15 localities in endemic and nonendemic goiter areas of western Colombia. A significant positive correlation was observed between goiter prevalence and AA in water collected from the pipelines of these localities. Samples at the water source showed only borderline significance. No significant correlation was observed in waters between AA and total hardness (ppm) or concentrations of Ca, Mg, sulfates, chlorides, silicates, nitrates, and iodine. AA was also demonstrated by this in vitro assay in well water previously shown experimentally to be goitrogenic and that supplied the endemic goiter district of Candelaria town in western Colombia. In contrast, water from the well supplying the area of lower endemicity was found to possess little AA. These results provide experimental support for epidemiological observations that demonstrate a relationship between the sources of drinking water and goiter prevalence rates, and are consistent with previous findings indicating that organic antithyroid compounds contaminate water supplies in areas where goiter persists despite adequate iodine supplementation.

Iodine deficiency (IDD) is one of the common problem in the diet. Iodine deficiency as prevalence of goiter in population occurs in the mountainous areas. There is consensus that 800 million people are at risk of IDD from living in iodine deficient area and 190 million from goiter. Very high prevalence of IDD in different parts of the world are striking. It has generally observed that in iodine-deficient areas about 50% are affected with goiter, 1-5% from cretinsim and 20% from impaired mental and/or mortor function. (A.B.).

Full Text Available Background. The purpose of our study was to determine the state of macro- and micronutrient support of patients with nodular thyroid pathology from the regions injured after the Chornobyl accident. Materials and methods. 65 habitants of the Chernihiv area were examined: 40 — without thyroid pathology (15 men and 25 women aged 36.62 ± 0.60 years, and 25 (5 men and 20 women — with the diagnosed nodular goiter. Results. Research of urinary iodine excretion showed that a median in the control group was 95.6 µg/l, among patients with nodular goiter — 89.3 µg/l, indicating the presence of moderate iodine deficiency. Blood thyroglobulin level in patients of control group was 9.26 ± 0.99 ng/l, among patients with nodular goiter — 23.03 ± 4.70 ng/l. Thyroid-stimulating hormone level higher than 4.0 mIU/l was in 8.9 % of patients with nodular goiter and in 5.0 % of persons from the control group. The data of ultrasonic researches demonstrated that the average thyroid volume in patients of control group was 10.1 ± 0.3 cm3, among patients with nodular goiter — 18.6 ± 1.7 cm3. In the group of patients with nodular goiter, the decreased (p < 0.0001 level of macronutrients in blood plasma was detected: calcium was 67.26 ± 3.21 µg/l and magnesium — 14.88 ± 0.35 µg/l, as well as of microelements: zinc content was 0.72 ± 0.04 µg/l (p < 0.0001 and iron — 0.54 ± 0.06 µg/l (p < 0.05, in comparison with the results in the control group.

This paper contains the results of scintigraphical and puncture-cytological examinations carried out during an observation period of appr. 3 years on 548 patients with goiters from the Upper-Bavarien endemis region. In total, we had 484 thyroid gland scintigrams which showed 335 uninodular, 71 multinodular, and 78 diffuse goiters. The 335 solitary nodular goiters were allocated 278 cold, 36 warm, and 18 hot nodes; in three cases, the scintigram could not be assessed due to exogenous iodine contamination. In the 71 multinodular goiters, we found 118 cold, 28 warm, and 9 hot nodes. Cytological findings were established in 548 patients. In 484 cases, the findings were negative, in 19 cases suspicious, and in 17 cases positive. The efficiency of cytological diagnosis of malignant tumours can be stated to be 87.5%. The rate of falsely negative smears was 12.5%; cytologically, in 10.9% of the preparations falsely suspicious diagnoses were established, and in 1.6% the diagnoses were falsely positive.

Thyroid pathology is frequent in Mali, which is an endemic zone for goiter. But this pathology rarely occurs in children. The purpose of our study was to characterize this illness among children in Mali. We report on patients aged less than 15-year old who presented with clinical signs and symptoms with hyperthyroidism at the medicine service at Hospital de Point G from January 1999 and December 2005 to determine the characteristics of hyperthyroidism. The frequency was 9.6 per thousand (38/3972), with an average age of 12.5+/-3.34-year. The sex ratio was 3 girls/1 boys. The most common symptoms were tachycardia (n=30, 78.9%), palpitations (n=15, 34.4%). 31 patients (81.5%) presented with exophthalmoses, 93.5% being bilateral. Weight loss was present in 31.5% (n=12). Goiter was present in 37 patients (97.4%). The goiter was diffuse in 27 patients (73%) and nodular in 10 (27.%). The presence of goiter caused signs of compression in the neck in half of the cases: dyspnea and dysphonia were the most common consequences. TSH less than 0.05 microUI/1 was used to confirm the diagnosis. Graves's disease was the most common cause (n=32, 84.2%), followed by toxic adenoma (n=4, 10.5%). Other causes included toxic multinodular goiter and thyroiditis. Etiologies were independent of sex and age: (p=0.95). All patients were started on medical therapy upon diagnosis. 7 patients (18.4%) were lost to follow-up during the 6 months of treatment. Remission was obtained in 26 patients (83.9%), and relapse occurred in 5 patients (16.1%). The frequency of hyperthyroidism in children in Mali is a problem in a goiter endemic zone like Mali. Poor general health in children and signs and symptoms of neck compression are markers of progressive disease.

A state of autoimmunity was studied in 25 patients, suffering diffuse toxic goiter (DTG), and in 20--in nodular euthyroid goiter (NEG) before and after the operation. The level of circulating immune complexes, quantity of cytotoxic lymphocytes, the subpopulation index, the apoptosis marker were determined. There was established, that in NEG autoimmune disorders have occurred rarer and were less severe, than in DTG.

The Relative Frequency of Persistent Hyperthyroidism After I131Therapy

International Nuclear Information System (INIS)

Al-EID, M.A.

1998-01-01

517 patients with different types of hyperthyroidism who had treated by I 131 therapy were studied. The study demonstrated that diffuse toxic goiter was the most common type of hyperthyroidism. The relative frequency of persistent hyperthyroidism in all types after the first dose of I 131 utilizing our empirical regimen in estimation of therapy doses was low (9.5%). While high frequency of persistent hyperthyroidism among diffuse toxic goiter patients (14%), probably was due to many factors discussed in this paper. Some of these factors are impossible to be estimated precisely and therefore, can not be avoided. But careful dose estimation for each case with diffuse toxic goiter may reduce the rate of retreatment by I 131 . Antithyroid medication prior to I 131 therapy might be another factor resulted in increasing of retreatment of retreatment rate diffuse toxic goiter cases. Longer time interval (more than 5 days) of ceasing antithyroid medication prior therapy is suggested to avoid the effects of these drugs. Patients with other types of hyperthyroidism were not frequently required more than one dose and the frequency of persistent hyperthyroidism was almost negligible

The values of the 3 and 24 hour thyroid radioiodine uptake were analysed in 919 of the patients examined during 1977-1980. Reference values determined for 95% of the normal population are 2.5 - 17.5% for the 3 hour thyroid uptake values, and 10.5 - 41.2% for the 24 hour values. The non-toxic diffuse goiter group has significantly higher mean values than normals or patients with non-toxic nodular goiters and cold nodules, their upper values reaching 24.7% and 52.9% for 3 and 24 hour uptake. The discriminatory power of the test for non-toxic diffuse goiters may be increased if higher limits than those determined for normals are used in day to day routine. Values of 20% for 3 hour uptake and 45% for the 24 hour uptake improve diagnosis in these patients without seriously reducing the capacity for identification of thyrotoxicosis. A value greater than 0.6 for the ratio between the 3 hour and 24 hour uptake can serve as a coadjuvant factor in the diagnosis of diffuse toxic goiters; values higher than 0.8 were found in less than 0.5% of the non-toxic patients.

Thyroid imaging in goiter

Since Cassen und Taylor and Stewart introduced 131 iodine scans of the thyroid, these have become an integral part of the routine diagnostic procedures for thyroid disease. Today 131 I is no longer used due to its excessive radioactivity; 123 iodine or 99m technetium are now preferred. Pitfalls in the use of 99m Tc are that in some thyroid disorders, such as certain forms of thyroid carcinomas and chronic thyroiditis, a normal iodine trapping (but not organification) may occur. This mechanism can lead to false conclusions. (orig.) [de

Purine Nucleoside Phosphorylase (PNP) Activity of Lymphocytes and T Cell Subsets in Peripheral Blood in Thyroid Tumors

Kim, Dong Soo

1992-01-01

To elucidate alteration of purine nucleoside phosphorylase (PNP) activity of peripheral lymphocytes and helper/inducer and suppressor/cytototxic T cells in patients with thyroid tumors, the author examined PNP activity, and CD4 + and CD8 + cells of peripheral blood in 20 cases of simple goiter, 9 cases of thyroid adenoma and 20 cases of thyroid cancer as well as 11 cases of adult healthy subjects as control. Diagnoses were established on the basis of commonly accepted clinical and biochemical criteria in simple goiter and were confirmed histopathologically in thyroid adenoma and cancer. All blood was obtained from veins of the patients and control subjects in Pusan National University Hospital during the period of January to August, 1991. The results obtained were summarized as follows: 1) The PNP activity was significantly decreased or tended to be decreased in thyroid adenomas and cancers as compared with control subjects and simple goiters. 2) The percentage of CD8 cells was significantly decreased or tended to be decreased in thyroid cancers as compared with simple goiters, thyroid adenomas and control subjects. 3) The CD4/CD8 ratio was significantly increased or tended to be increased in thyroid cancer as compared with simple goiters, thyroid adenomas and control subjects. On the basis of the results, it can be suggested that the immunodysfunction in thyroid cancer may be due to decreased suppressor/cytotoxic T cells, and the estimation of PNP activity of peripheral lymphocyte is a helpful test in detecting the immune status in thyroid tumors.

Hyperthyroidism includes several clinical and histopathological situations. Surgery is commonly indicated after failure of medical treatment. The aim of this study was to analyze the indications and complications of surgery as well as endocrine results. Patients operated on for hyperthyroidism between 2004 and 2012 were included in a retrospective study. Total thyroidectomy was performed for Graves' disease, toxic multinodular goiter and amiodarone-associated thyrotoxicosis; patients with toxic nodule underwent hemithyroidectomy. Pathologic analysis assessed surgical specimens; postoperative complications and resolution of hyperthyroidism were noted. Two hundred patients from 15 to 83 years old were included. One hundred and eighty-eight underwent primary surgery and 12 were re-operated for recurrent goiter (6 with subtotal thyroidectomy for multinodular goiter 25 years previously; 6 with hemithyroidectomy for solitary nodule 15 years previously). Eighty-two patients suffered from toxic multinodular goiter, 78 from Graves' disease, 35 from solitary toxic nodules and 5 from amiodarone-associated thyrotoxicosis. Fourteen papillary carcinomas (including 11 papillary microcarcinomas) and 34 healthy parathyroid glands (17%) were identified in the pathological specimens. Postoperative complications comprised 4% permanent recurrent laryngeal nerve palsy (1 year follow-up), 9% hematoma requiring surgical revision, and 3% definitive hypocalcemia. Normalization of thyroid hormone levels was observed in 198 patients. Two recurrences occurred due to incomplete resection (1 case of Graves' disease and 1 intrathoracic toxic goiter that occurred respectively 18 and 5 months after resection). Postoperative complications were more frequent in multinodular goiter (23%) than in Graves' disease (13%) (ns: P>0.05). Surgical management of hyperthyroidism enables good endocrinal control if surgery is complete. Patients need to be fully informed of all possible postoperative complications

The incidence of thyroid carcinoma in hyperthyroidism varies considerably from as low as 0.3% to as high as 16.6% with a higher rate in toxic nodular goiters. Occult thyroid carcinoma (thyroid carcinoma was 5.6% (23 cases). In detail, a neoplasm occurred in 5 cases of Graves' disease (specific incidence: 3.8%), in 13 cases of toxic nodular goiter (12.5%) and in 5 cases of hyperfunctioning adenomas (2.8%). 19 cancers were papillary (12 in toxic nodular goiter, 3 in Graves' disease, 4 in hyperfunctioning adenomas), three were follicular (1 in Graves' disease, 1 in toxic nodular goiter, 1 in hyperfunctioning adenomas) and 1 medullary in Graves' disease. A papillary carcinoma was diagnosed preoperatively on fine needle aspiration with ultrasonography in only two patients with Graves' disease and confirmed by postoperative histological examination on permanent section. We do not believe in the frozen-section examination intraoperatively because it's not diagnostical for follicular lesions and evaluates rarely capsular invasion. Twenty patients received total thyroidectomy and four of them also lymphoadenectomy. Three patients received emithyroidectomy: in two cases for occult papillary carcinoma and in the last case for local cancer invasion (T4N0M0). Twenty patients are alive and with no evidence of cancer recurrence. Mean follow-up is 59.6 months. Our retrospective study shows a progressive increase of the incidence of coexisting thyroid malignancy and hyperthyroidism especially in toxic nodular goiter, probably related to extended surgical indications. Our findings do confirm that, even in the presence of hyperthyroidism, all thyroid nodules require careful diagnostics for exclusion of malignancy.

Hashimoto thyroiditis (HT) is an autoimmune thyroid disorder that usually presents as a diffuse, nontender goiter, whereas subacute thyroiditis (SAT) is an uncommon disease that is characterized by tender thyroid enlargement, transient thyrotoxicosis, and an elevated erythrocyte sedimentation rate (ESR). Very rarely, patients with HT can present with painful, tender goiter or fever, a mimic of SAT. We report a case of painful HT in a 68-year-old woman who presented with pain and tenderness in a chronic goiter. Her ESR was definitely elevated and her thyroid laboratory tests suggested subclinical hypothyroidism of autoimmune origin. 99mTc pertechnetate uptake was markedly decreased. Fine needle aspiration biopsy revealed reactive and polymorphous lymphoid cells and occasional epithelial cells with Hürthle cell changes. Her clinical symptoms showed a dramatic response to glucocorticoid treatment. She became hypothyroid finally and is now on levothyroxine therapy. PMID:22570820

Full Text Available A complex examination detected that kalium iodide dosage 100 mkg daily promote a rapid normalization of median of ioduria in children aged 8 to 12 years. Even in a case of normal initial level of ioduria iod active at the same dosage doesn't promote an increase of median of ioduria over than optimum level. It wasn't detected any decrease of goiter frequency during 6 months of prophylaxis, while the level of some cognitive indexes (an attention and the frequency of absence from school by the reason of acute respiratory deseases significantly increased. It could be concluded, that iodine prophylaxis using iod active is more effective in mild goiter endemia combine to decrease of attention in prepubertal children. In the case of combination of moderate endemic goiter and normal cognitive function kalium iodide is more preferable in prophylaxis in children.Key words: children, iod deficiency, prophylaxis.

Aim To assess iodine supply and follow thyroid epidemiology for ten years after an iodine increase from 10 to 25 mg of potassium iodide per kilogram of salt in 1999. Methods In 2002 and 2003, we determined the thyroid size by palpation and ultrasound and measured urinary iodine concentration (UIC) in 676 schoolchildren from 34 schools throughout Slovenia. From 1999 to 2009, we followed the incidence of diffuse and nodular goiter, thyroid autonomy, Graves’ disease, and Hashimoto’s thyroiditis among adults in the stable catchment area of the University Medical Centre Ljubljana with 1 000 000 inhabitants. Results In children, only 1% had a goiter grade 2 (visible and palpable thyroid gland), median thyroid volume was 5.8 mL, and median UIC was 148 µg/L. In adults, the incidence of diffuse goiter and thyroid autonomy decreased significantly (2009 vs 1999, rate ratio [RR], 0.16; 95% confidence interval [CI], 0.12-0.21 and RR, 0.73; 95% CI, 0.62-0.86, respectively), with a lower incidence in younger participants in 2009 (P < 0.001). The incidence of multinodular goiter and solitary nodule increased (2009 vs 1999, RR, 1.55; 95% CI, 1.35-1.79 and RR, 1.72; 95% CI, 1.49-1.99, respectively). No long-term changes were observed for Graves’ disease (2009 vs 1999, RR, 0.95; 95% CI, 0.81-1.13), while the incidence of Hashimoto’s thyroiditis increased strongly (2009 vs 1999, RR, 1.86; 95% CI, 1.64-2.12). Conclusions The change from mildly deficient to sufficient iodine supply was associated with a marked change in the incidence of thyroid epidemiology – a significant decline in the incidence of diffuse goiter and thyroid autonomy and a marked increase in the incidence of Hashimoto’s thyroiditis.

Full Text Available Thomas P Vacek, Shahnaz Rehman, Shipeng Yu, Ankush Moza, Ragheb Assaly Department of Internal Medicine, The University of Toledo Medical Center, Toledo OH, USAAbstract: Chest pain requires a detailed differential diagnosis with good history-taking skills to differentiate between cardiogenic and noncardiogenic causes. Moreover, when other symptoms such as fever and elevated white blood cell count are involved, it may be necessary to consider causes that include infectious sources. A 53-year-old female with no significant past medical history returned to the hospital with recurrent complaints of chest pain that was constant, substernal, reproducible, and exacerbated with inspiration and expiration. The chest pain was thought to be noncardiogenic, as electrocardiography did not demonstrate changes, and cardiac enzymes were found to be negative for signs of ischemia. The patient's blood cultures were analyzed from a previous admission and were shown to be positive for Staphylococcus aureus. The patient was started empirically on vancomycin, which was later switched to ceftriaxone as the bacteria were more sensitive to this antibiotic. A transthoracic echocardiogram did not demonstrate any vegetation or signs of endocarditis. There was a small right pleural effusion discovered on X-ray. Therefore, computed tomography as well as magnetic resonance imaging of the chest were performed, and showed osteomyelitis of the chest. The patient was continued on intravenous ceftriaxone for a total of 6 weeks. Tests for HIV, hepatitis A, B, and C were all found to be negative. The patient had no history of childhood illness, recurrent infections, or previous trauma to the chest, and had had no recent respiratory infections, pneumonia, or any underlying lung condition. Hence, her condition was thought to be a case of primary sternal osteomyelitis without known cause.Keywords: substernal, pleuritic, myocardial infarction, differential

Treatment of hyperthyroidism with radioactive iodine

International Nuclear Information System (INIS)

Bell, R.L.

1974-01-01

While radioactive iodine is clearly the therapy of choice for Graves' disease (even in younger patients) the use of radioactive iodine for therapy of the toxic multinodular or uninodular goiter presents an entirely different problem. Although these two entities can be treated with radioactive iodine provided there is some suppression of the tissue that is not autonomous, transient release of thyroid hormone may induce symptoms of thyroid storm in the very large multinodular toxic goiter treated with radioiodine therapy. These toxic nodules generally require much larger doses of radioiodine than is commonly used for classical Graves' disease and may either require fractional administration of radioisotopes or concomitant use of antithyroid drugs and iodides. In general, surgery remains the treatment of choice for large toxic multinodular goiters, after proper preparation by medical means including radioactive iodine. Radioactive iodine therapy for hyperthyroidism is contraindicated in pregnancy and generally is not used in children below five years of age. (U.S.)

A bout 1628 school going children were surveyed for the assessment of iodine deficiency in school going children in Abbottabad city, The purpose of this survey was to find out prevalence of goiter, severity of iodine deficiency and iodine content of the salts used by the people of the area. It was found that total goiter rate (TGR) was 23.9%. Among males 176 (23.1%) and among females 214 (24.7) were suffering from goiter, On the basis of urinary iodine (UI) 5.2% children were facing severe. Analysis of salts provided by students showed that 58.8% families were using salts with recommended level of iodine while the remaining 41-2% families were using salts with inadequate quantity of iodine. It is clear iodine deficiency is still a major public health problem in the area and most of the people in the area do not use iodized salt with recommended level of iodine. (A.B.)

At the same time the frequency of regional lymph node metas tases was significantly higher in patients with thyroid nodules larger than 2 cm (34.8%, than in patients with nod ules less than 2 cm – 18.3%. Only one malignant tumor was detected among 358 patients with autonomously func tioning nodules. Risk groups with higher rate of malignancy were patients living in the areas with Chernobyl’s fall out, and patients in whom nodules with “suspicious” sonographic features were revealed (rough edges, capsule inva sion, microcalcifications. Patients with high risk of malignant transformation should be submitted to FNAB regard less of thyroid nodule size. Biopsy is unnecessary for the patients with autonomously functioning nodules detected by scintigraphy.

Full Text Available Severe iodine deficiency results in impaired thyroid hormone synthesis and thyroid enlargement. In the United States, adequate iodine intake is a concern for women of childbearing age and pregnant women. Beyond this high risk group iodine deficiency is not considered to be a significant problem. This case report describes a 12-year-old male with severe iodine deficiency disorder (IDD resulting from restricted dietary intake due to multiple food allergies. We describe iodine replacement for this patient and continued monitoring for iodine sufficiency. Children with multiple food allergies, in particular those with restrictions to iodized salt and seafood, should be considered high risk for severe iodine deficiency.

Background: There is not an optimal treatment for multinodular goiter (MNG). Surgery is the main therapeutic option because it decreases thyroid volume, reduces compression symptoms and provide histological diagnosis. Radioiodine ({sup 131}I) is an efficient therapeutic option for the treatment of MNG mainly when surgery is not indicated or when the patient refused it. However, high activities of {sup 131}I are frequently required for clinically significant results. This procedure increases the body radiation exposure and the hospitalization costs. Recombinant human TSH (rh TSH) allows a reduction in the administered activity of {sup 131}I with effective thyroid volume (TV) reduction. However, this combination therapeutic can increase collateral effects. Objective: To evaluate the efficacy and safety of low and intermediate doses of rh TSH compared to placebo, associated with a fixed activity of {sup 131}I in MNG treatment. Patients and Methods: Thirty patients with MNG received 0.1 mg of rh TSH (group I, n=10), 0.01 mg of rh TSH (group II, n=10), or placebo (control group, n=10). After 24 hours, 30 mCi of {sup 131}I was given to all patients. Radioactive iodine uptake (RAIU) was determined before and 24 hours after rh TSH. Before and 2, 7, 180 and 360 days after the TV was measured by magnetic resonance image (MRI). The smallest cross-sectional area of tracheal lumen (Scat) was also measured with MRI before, 2 and 7 days after treatment. Antithyroid antibodies, TSH, T3 and free T4 were assessed regularly. Results: After 6 months, the decrease in TV was more significant in groups I (30.3 +- 16.5%) and II (22.6 +- 14.5%), than in control group (5.0 +- 14.6%; p=0.01). After 12 months, TV decreased more in group I (39.2 +- 16.9%) and group II (38.8 +- 24.4%) than in group III (23.4 +- 23.59%) but it was not statistically significant (p=0.205). During the first 30 days,total T3 and free T4 increased, without reaching thyrotoxic levels and TSH decreased. After 12 months

Female residents of 13 counties of Western Washington, in whom papillary, follicular, or mixed papillary-follicular thyroid carcinomas had been diagnosed between 1974 and 1979 were interviewed regarding their medical and reproductive histories and past exposure to radiation treatments. For comparison, a random sample of women from the same population was interviewed. Women who had received radiation treatments to the head or neck prior to 5 years before interview were 16.5 times (95% confidence interval . 8.1-33.5) more likely than unexposed women to develop cancer. The relative risk (RR) was highest for papillary cancer (19.4) but also was elevated substantially for follicular and mixed papillary-follicular tumors. Women first irradiated at age 19 years or younger had a much higher RR than did women irradiated at age 20 or older. Regardless of prior radiation exposure, women who ever had had a goiter were at increased risk of developing thyroid cancer. Women who had ever developed a goiter had 17 times the risk of developing follicular cancer and almost 7 times the risk of developing papillary cancer as compared with women who never had had a goiter. Risk of thyroid cancer was elevated even among women who had had a history of goiter many years prior to diagnosis. A history of thyroid nodules was also a risk factor for papillary and mixed thyroid cancer. Neither a history of hypothyroidism nor hyperthyroidism was found to increase the risk of thyroid cancer

Full Text Available Background: Determination of thyroid volume using ultrasound has been recommended for monitoring public control of iodine deficiency programs in areas with mild iodine deficiency or with no iodine deficiency, instead of physical examination, in order to estimate the prevalence rate of goiter. The aim of this study was to determine the reference ranges of thyroid volume in Bushehr port. Methods: Thyroid volume of 1247 primary schoolchildren aged 7-10 years who were selected by probability proportionate to size method from rural and urban areas of Bushehr port was determined using ultrasonography. Medians and percentiles of thyroid volumes for age and body surface area were calculated for both genders. Results: The 97th percentiles of thyroid volume of Bushehr port schoolchildren according to age and sex were all lower than the corresponding sex-specific normative WHO reference values. Goiter prevalence was 1.68% according to WHO thyroid volume references for age in the studied population. The goiter prevalence according to age and body surface area-specific new normative WHO reference values were 7.13 and 7.17%, respectively. Conclusion: The 97th percentile for thyroid volume, calculated by ultrasonography in Bushehr port schoolchildren, were lower than the international WHO newly recommended reference values in all ages. Therefore, determination of a native reference value for estimating the prevalence rate of thyroid is highly recommended. According to ultrasonographically determined goiter prevalence, Bushehr is an iodine sufficient area.

Clinical relevancy of a sensitive TSH-RIA

Based on a sensitive TSH-RIA (measuring range 0.2-25 mU/l, 50%-intercept 2 mU/l, coefficients of between-assay-variation 5-10%) and on nearly 1200 cases, it is demonstrated that clinical results can be received by determination of basal serum TSH alone. Values above 0.5 mU TSH/l indicate positive TRH tests in a good correlation between increasing basal concentrations and pituitary TSH reserve. TSH levels below 0.3 mU/l proceed with negative TRH tests. In selected healthy subjects, we found all TSH values between 0.7 and nearly 5 mU/l (x-bar = 1.99). In euthyroid goiters TSH levels are normally in the same range, but in nodular goiters, subnormal values were found accumulated. TSH levels below 0.3 mU/l are helpful to discover non-suppressibility. Hormone treatment of goiters is successful above all in case of high-normal pretherapeutic TSH values. 'Fine-tuning' of hormone dosage (goiter treatment, postoperative prophylaxis, suppression therapy in thyroid carcinoma) as well as monitoring of thyrotoxicosis treatment is recommended to be performed by means of basal TSH determination. In pituitary disorders, thyroid hormone treatment seems to be necessary only at TSH levels below 0.5 mU/l. Combination of basal TSH and total T 3 is economical and describes nearly all functional situations in diagnosis and treatment of thyroid diseases. (author)

The Belarus-American (BelAm) thyroid study cohort consists of persons who were 0-18 years of age at the time of exposure to radioactive iodine fallout from the 1986 Chernobyl nuclear power plant accident and who have undergone serial thyroid screenings with referral for fine-needle aspiration biopsy (FNAB) using standardized criteria. We investigated thyrocyte nuclear abnormalities in cytological samples from FNABs in 75 BelAm subjects with single and multiple thyroid nodules and 47 nodular goiter patients from Leningrad, Russia, unexposed to Chernobyl fallout. Nuclear abnormalities examined included internuclear chromosome bridges and derivative nuclei with broken bridges (i.e., ''tailed'' nuclei), which are formed from dicentric and ring chromosomes and thus may be cellular markers of radiation exposure. Among subjects with single-nodular goiter, thyrocytes with bridges were present in 86.8% of the exposed BelAm cohort compared with 27.0% of unexposed controls. The average frequency of thyrocytes with bridges and with tailed nuclei was also significantly higher in the BelAm subjects than in controls. Among subjects with multinodular goiters, thyrocytes with bridges were present in 75.7% of exposed BelAm patients compared with 16.7% of unexposed controls; thyrocytes with tailed nuclei were observed in all of the BelAm subjects but in only 40% of controls, and the mean frequencies of bridges and tailed nuclei were significantly higher in the exposed group. Unusually, long bridges were detected in 29% of BelAm patients with single-nodular goiters and 35% of those with multinodular goiters, while no such abnormalities were observed among patients from the Leningrad region. In the exposed subjects from BelAm, we also found positive correlations between their estimated dose of Iodine-131 from Chernobyl fallout and the frequency of tailed nuclei (p = 0.008) and bridges (p = 0.09).

Two hundred and sixty one Indian women from Delhi and surrounding territory were prospectively evaluated to determine the frequency of post-partum thyroiditis upto 12 weeks of postpartum. Thirty one (11.8%) of the 261 cases included in our study developed thyroid disease. Twenty four (77%) of the patients who developed thyroiditis were found to have high titres of thyroid antibodies. Of these 24 patients, 21 (67.7%) tested positive for antimicrosomal antibodies and 17 (54.8%) tested positive for antithyroglobulin antibodies. Patients were found to have a spectrum of thyroid dysfunction. Transient hypothyroidism developed in 17 patients, I patient developed persistent hypothyroidism, 7 had transient thyrotoxicosis and 6 developed euthyroid goiters. Twenty two patients had goiters ranging from grade OB to grade II. Fine needle aspiration cytology showed chronic lymphocytic thyroiditis in 20 patients, while 2 had colloid goiter. It is concluded from our study that there is a significant incidence of post partum thyroid disease in the female population representative of North India, and most of the patients (93.5%) develop transient thyroid disorder.

Full Text Available Thyroid storm is a rare but life-threatening condition, which can be induced by many critical diseases. We reported a 40-year-old woman with thyroid goiter manifesting with acute sepsis-induced hyperthyroidism. She mainly presented with abdominal bloating, diarrhea, lower limbs edema and exertional dyspnea. The lactate was 9.5 mmol/L and procalcitonin was 3.8 ng/mL, suggesting acute sepsis. The thyroid echo showed bilateral thyroid goiter. Relevant data included a thyroid-stimulating hormone level of 0.03 μIU/mL; free tetraiodothyronine, 5.67 ng/dL; thyroid-stimulating hormone receptor antibody, 76.9% (normal range, < 14%; and antimicrosomal antibody titer, 1:102400 (normal range, < 1:100, suggesting toxic goiter with thyroid storm. Piperacillin/tazobactam, methimazole and Lugol's iodine achieved a good outcome. The symptoms of early sepsis and those of thyroid storm could be similar. Therefore, a careful history taking, a thorough physical examination and a high degree of suspicion could make early diagnosis and appropriate treatment.

Differential diagnosis of hyperthyroidism

Energy Technology Data Exchange (ETDEWEB)

Emrich, D.

1984-04-23

There are probably two reasons for hyperthyroidism: 1. A disturbance in the immune system. This leads to the production of autoantibodies which predominantly stimulate thyroid function. 2. An increased formation of autonomus follicles in the thyroid gland during the development of a goiter. Autonomus follicies can be located within the thyroid gland in a focal or disseminated pattern. They are found predominantly in bigger, long-standing goiters with degenerative areas. The extent of autonomy is probably determined by the amount to autonomous follicles and their activity. In the euthyroid state autonomy can be detected by a subnormal TRH test. Quantitative scintigraphy under suppression is probably more sensitive. In goiters with autonomy, transition from the euthyroid into the hyperthyroid state especially in areas of iodine deficiency is often induced by application of iodine containing drugs and X-ray media. It the patient is already in a hyperthyroid state its immunogenic and non-immunogenic origin can be recognized with rather high probability by certain clinical symptoms and by some simple laboratory investigations. This may have significance for the selection of therapy.

1996-01-01

The present article provides an update on IDD in the Western regions of Russia (Bryansk, Kaluga, Tula and Orel) which were contaminated by radioactive fallout after the Chernobyl accident in 1986. These surveyed areas meet the criteria of ICCIDD/UNICEF/WHO for mild and moderate IDD. Higher iodine excretion and smaller goiter prevalence (mild level of IDD) were more typical for urban sites, while lower iodine levels and higher goiter endemicity (moderate level of IDD) were found in rural areas. IDD control programmes should be developed and implemented in Chernobyl areas and iodine excretion should be monitored continuously to minimize future thyroid abnormalities

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

A 66-year-old woman with Pendred's syndrome underwent a partial thyroidectomy when she was 17 years old. At the age of 52 years, she had a second thyroid operation because of hyperthyroidism due to a toxic multinodular goiter with a mediastinal extension consisting of several separate nodules. Five years later a hyperfunctioning metastatic follicular carcinoma was diagnosed histologically. After treatment with radioactive iodine, the patient was well. To the authors' knowledge, this is the first description of a metastatic follicular thyroid carcinoma in Pendred's syndrome and the first report of hyperthyroidism occurring after malignant degeneration of a dyshormonogenetic goiter

Full Text Available Appropriate hydration is a very important prognostic factor for the patient’s health. Ultrasonographic assessment of hydration status is rarely used in pediatric medicine and it is not used at all in neonates due to the fact that no reference values have been established for this age group. The aim of the paper was to establish reference values for neonates. Material and methods: The study included 50 neonates from two hospitals in the Lower Silesia region of Poland; 25 of them were healthy patients (full-term newborns with no perinatal complications and 25 were sick patients (newborns with heart defects such as ostium secundum atrial septal defect, ventricular septal defect, permanent foramen ovale and patent ductus arteriosus as well as newborns with neonatal jaundice or pneumonia that occurred during the first days of life. The ultrasound scans were conducted during the first days of the children’s life. For every child inferior vena cava diameter was measured in the substernal area, longitudinal plane, M-mode in two respiratory phases: inhalation and exhalation. In addition, abdominal aorta diameter was determined (substernal area, transverse plane. Results: The study demonstrated a statistically significant difference in the calculated inferior vena cava collapsibility index between both groups. Two other indices included the ratio of the inferior vena cava diameter during the expiratory phase to the diameter of the aorta and the ratio of the inferior vena cava diameter during the inspiratory phase to the diameter of the aorta; a statistically significant difference between both groups was found only for the measurements in the inspiratory phase. Conclusions: Based on the study results normal ranges for hydration indices in neonates were established. The need for the measurement of the abovementioned parameters in the inspiratory phase was determined. In addition, the usefulness of the ultrasound examination for the evaluation of body

Ultrasonographic assessment of hydration status is rarely used in pediatric medicine and it is not used at all in neonates due to the fact that no reference values have been established for this age group. The aim of the paper was to establish reference values for neonates. The study included 50 neonates from two hospitals in the Lower Silesia region of Poland; 25 of them were healthy patients (full-term newborns with no perinatal complications) and 25 were sick patients (newborns with heart defects such as ostium secundum atrial septal defect, ventricular septal defect, permanent foramen ovale and patent ductus arteriosus as well as newborns with neonatal jaundice or pneumonia that occurred during the first days of life). The ultrasound scans were conducted during the first days of the children's life. For every child inferior vena cava diameter was measured in the substernal area, longitudinal plane, M-mode in two respiratory phases: inhalation and exhalation. In addition, abdominal aorta diameter was determined (substernal area, transverse plane). The study demonstrated a statistically significant difference in the calculated inferior vena cava collapsibility index between both groups. Two other indices included the ratio of the inferior vena cava diameter during the expiratory phase to the diameter of the aorta and the ratio of the inferior vena cava diameter during the inspiratory phase to the diameter of the aorta; a statistically significant difference between both groups was found only for the measurements in the inspiratory phase. Based on the study results normal ranges for hydration indices in neonates were established. The need for the measurement of the abovementioned parameters in the inspiratory phase was determined. In addition, the usefulness of the ultrasound examination for the evaluation of body fluid status in this pediatric age group, particularly in preterm

Full Text Available Case summary Primary goitrous hypothyroidism was diagnosed in a 12-month-old cat examined because of small stature, mental dullness, severe lethargy, generalized weakness and gait abnormalities. Radiographs of the long bones and spine revealed delayed epiphyseal ossification and epiphyseal dysgenesis. Diagnosis of primary hypothyroidism was confirmed by low serum concentrations of total and free thyroxine (T4 with high thyroid-stimulating hormone (TSH concentrations. Thyroid scintigraphy revealed severe enlargement of both thyroid lobes, as evidenced by a seven-fold increase in calculated thyroid volume above the reference interval. In addition, this bilateral goiter had an extremely high radionuclide uptake, about 10-fold higher than the normal feline thyroid gland. Treatment with twice-daily levothyroxine (L-T4, administered on an empty stomach, resulted in increased alertness, playfulness, strength and improvement in gait, as well as an increase in body length and weight. L-T4 replacement also led to normalization of serum thyroid hormone and TSH concentrations, and complete resolution of goiter. Relevance and novel information Spontaneous hypothyroidism is rarely reported in cats, with congenital hypothyroidism in kittens diagnosed most frequently. Despite the fact that this cat was a young adult, it likely had a form of congenital hypothyroidism caused by dyshormonogenesis (defect in thyroid hormone synthesis that led to compensatory development of goiter. In hypothyroid cats, treatment with L-T4 is best given twice daily on an empty stomach to ensure adequate absorption. Normalization of serum TSH and shrinkage of goiter, as well as improvement in clinical signs, is the goal of treatment for cats with goitrous hypothyroidism.

Full Text Available Objective. Thyroid-related emergencies are caused by overt dysfunction of the gland that are so severe that require admission to intensive care units frequently. Nonetheless, in the ICU setting, it is crucial to differentiate patients with non-thyroidal illness and alterations in thyroid function tests from those with intrinsic thyroid disease. This review presents and discusses the main etiopathogenetical and clinical aspects of hypothyroid coma (HC and thyrotoxic storm (TS, including therapeutic strategy flow-charts. Furthermore, a special chapter is dedicated to the approach to massive goiter, which represents a surgical thyroid emergency.Data source. We searched the electronic MEDLINE database to September 2013.Data selection and Data extraction. Reviews, original articles and case reports on myxedematous coma, hypothyroid coma, thyroid storm, thyrotoxic storm, massive goiter, huge goiter, prevalence, etiology, diagnosis, therapy, prognosis were selected.Data synthesis and conclusions. Severe excess or defect of thyroid hormone are rare conditions which jeopardize the life of patients in most cases. Both HC and TS are triggered by precipitating factors, which occur in patients with severe hypothyroidism or thyrotoxicosis, respectively. The pillars of HC therapy are: high dose l-thyroxine and/or tri-iodothyroinine; i.v. glucocorticoids; treatment of hydro-electrolyte imbalance (mainly, hyponatraemia; treatment of hypothermia; not rarely, endotracheal intubation and assisted mechanic ventilation are needed. Therapy of TS is based on beta-blockers, thyrostatics, and i.v. glucocorticoids; eventually, high-dose iodide compounds or lithium carbonate may be of benefit. Surgery represents the gold standard treatment in patients with euthyroid massive nodular goiter, although new techniques – e.g., percutaneous laser ablation - are helpful in subjects at high surgical risk or refusing operation.

The action of somatostatin (SRIH) on 3 H-thymidine (thy) incorporation and on c-myc and thyroglobulin RNA levels in a suspension of follicles from normal and goitrous human thyroid was examined. SRIH, at 10 - 7 M concentration, inhibited basal thy incorporation (maximally by 4 h lasting for up 24 h), which effect was greater in goiter than in normal thyroid and was also detected in growing adherent epithelial cells. Moreover, in a follicle suspension SRIH prevented TSH-stimulated thy incorporation, both in normal and in goitrous thyroid. Basal expression of c-myc RNA was not affected by SRIH in either tissue, whereas the TSH-stimulated c-myc RNA level was significantly reduced in goiter. No effect of SRIH was observed on basal or TSH-stimulated thyroglobulin RNA levels. SRIH did not alter basal cAMP concentrations in normal or goitrous follicles, but it significantly reduced TSH-stimulated cAMP accumulation both in normal thyroid and in goiter. Overall, our data indicate a direct inhibitory action of SRIH on growth, but not on differentiation, of human thyroid, probably by a mechanism not entirely cAMP dependent

Hyperthyroidism: diagnosis and treatment.

The proper treatment of hyperthyroidism depends on recognition of the signs and symptoms of the disease and determination of the etiology. The most common cause of hyperthyroidism is Graves' disease. Other common causes include thyroiditis, toxic multinodular goiter, toxic adenomas, and side effects of certain medications. The diagnostic workup begins with a thyroid-stimulating hormone level test. When test results are uncertain, measuring radionuclide uptake helps distinguish among possible causes. When thyroiditis is the cause, symptomatic treatment usually is sufficient because the associated hyperthyroidism is transient. Graves' disease, toxic multinodular goiter, and toxic adenoma can be treated with radioactive iodine, antithyroid drugs, or surgery, but in the United States, radioactive iodine is the treatment of choice in patients without contraindications. Thyroidectomy is an option when other treatments fail or are contraindicated, or when a goiter is causing compressive symptoms. Some new therapies are under investigation. Special treatment consideration must be given to patients who are pregnant or breastfeeding, as well as those with Graves' ophthalmopathy or amiodarone-induced hyperthyroidism. Patients' desires must be considered when deciding on appropriate therapy, and dose monitoring is essential.

Thyrotoxicosis is a pathological syndrome in which tissue is exposed to excessive amounts of circulating thyroid hormones. Including its subclinical form, it is considered as one of the most frequent endocrine disorders in the general population. If not detected in a timely fashion, thyrotoxicosis can have serious health consequences. The most common forms of thyrotoxicosis include diffuse toxic goiter (Graves' disease), toxic multinodular goiter (Plummer's disease), and toxic adenoma (Goetsch's disease). The significant progress in the fields of hormonal assessment, imaging procedures and molecular biology made in recent years has brought about great improvement in the identification, differentiation and treatment of many other disorders associated with thyrotoxicosis. Therefore, this paper discusses the etiopathogenesis, clinical manifestation, biochemical abnormalities and management of thyrotropinoma, resistance to thyroid hormone, de Quervain's, silent, acute, posttraumatic and radiation-induced thyroiditis, Riedel's goiter, differentiated thyroid cancer, struma ovarii, thyrotoxicosis factitia, other forms of iatrogenic thyrotoxicosis, gestational trophoblastic disease, neonatal Graves's disease, familial nonautoimmune hyperthyroidism and McCune-Albright syndrome. On the basis of available studies, some of whom were carried out in the recent years, we provide practical guidelines for clinical endocrinologists dealing with the diagnosis and treatment of thyrotoxicosis.

Various clinical disorders can cause hyperthyroidism, the effects of which vary according to the patient's age, severity of clinical presentation and association with other comorbidities. Hyperthyroidism is associated with increased morbidity and mortality from cardiovascular disease, although whether the risk of specific cardiovascular complications is related to the etiology of hyperthyroidism is unknown. This article will focus on patients with Graves disease, toxic adenoma and toxic multinodular goiter, and will compare the cardiovascular risks associated with these diseases. Patients with toxic multinodular goiter have a higher cardiovascular risk than do patients with Graves disease, although cardiovascular complications in both groups are differentially influenced by the patient's age and the cause of hyperthyroidism. Atrial fibrillation, atrial enlargement and congestive heart failure are important cardiac complications of hyperthyroidism and are prevalent in patients aged > or = 60 years with toxic multinodular goiter, particularly in those with underlying cardiac disease. An increased risk of stroke is common in patients > 65 years of age with atrial fibrillation. Graves disease is linked with autoimmune complications, such as cardiac valve involvement, pulmonary arterial hypertension and specific cardiomyopathy. Consequently, the etiology of hyperthyroidism must be established to enable correct treatment of the disease and the cardiovascular complications.

A 21-year-old man presented with pleuritic substernal chest pain of one hour's duration. The pain was exacerbated in a supine position and did not radiate. Questioning revealed that he was a recreational user of cocaine and had inhaled free-based cocaine via a pipe the previous evening and as recently as two hours before admission to the hospital. Physical examination demonstrated an anxious young man with a respiratory rate of 26 breaths per minute and shallow. He was afebrile with normal heart rate and blood pressure. His sternum was tender to palpation, and auscultation revealed precordial crepitus synchronous with systole. His electrocardiogram showed sinus rhythm at a rate of 62 beats per minute. Posteroanterior and lateral roentgenograms of the chest were obtained. A diagnosis of spontaneous pneumomediastinum was made

Subclinical and overt hyperthyroidism have been associated with various negative clinical outcomes as for example an increased risk of atrial fibrillation or increased cardiovascular mortality, especially in old age. In order to avoid hyperthyroidism it is strongly recommended not to start any iodine containing drug therapy or to avoid application of contrast agents unless the patient presents with an unremarkable clinical course. TSH suppressive therapy for the treatment of endemic goiter or differentiated low risk thyroid carcinoma is unnecessary, since it favours the development of subclinical hyperthyroidism. Overt hyperthyroidism is treated with antithyroid drugs and/or radioiodine therapy or surgery according to the underlying disease (toxic nodular goiter, Graves' disease).

Hyperfunctioning metastatic follicular thyroid carcinoma in Pendred's syndrome

Abs, R.; Verhelst, J.; Schoofs, E.; De Somer, E. (University Hospital, Antwerp (Belgium))

1991-04-15

A 66-year-old woman with Pendred's syndrome underwent a partial thyroidectomy when she was 17 years old. At the age of 52 years, she had a second thyroid operation because of hyperthyroidism due to a toxic multinodular goiter with a mediastinal extension consisting of several separate nodules. Five years later a hyperfunctioning metastatic follicular carcinoma was diagnosed histologically. After treatment with radioactive iodine, the patient was well. To the authors' knowledge, this is the first description of a metastatic follicular thyroid carcinoma in Pendred's syndrome and the first report of hyperthyroidism occurring after malignant degeneration of a dyshormonogenetic goiter.

Therapy of endemic goiter and hypothyroidism

Successful treatment of endemic goitre depends on the correct diagnosis and the comprehension of the pathophysiologic changes as well. Several criteria, e.g. anamnestic data, general clinical condition, local symptoms and signs, certainty of diagnosis, contraindications, rates of success, and side effects, determine the particular form of therapy (suppression with thyroid hormones, surgical resection, radio-iodine). The decision criteria are discussed. Prophylaxis of recurrent goitre with either thyroid hormones or iodine salts is necessary after successful treatment. Some endemic goitres behave like either hyper- or hypothyroidism. Treatment with thyroid hormones of patients with latent hyperthyroidism is senseless and dangerous, whereas other methods of treatment may be applied. An unequivocal indication for treatment exists in patients with latent hypothyroidism accompanied by goitre, but not in all patients without goitre. Hormonal replacement therapy of manifest hypothydroidism is simple, but long term success is not achieved in all patients.

Thyroidectomy is performed for hyperthyroidism on patients who do not respond to or are not compliant with medical therapy and in patients with very large goiters causing compressive symptoms. All thyrotoxic patients undergoing thyroidectomy usually are first treated with anti-thyroid drugs to normalize free thyroid hormone levels and render them euthyroid before surgery in order to prevent complications particularly thyroid storm and circulatory collapse. In this case series, we describe the clinical outcome during the perioperative (thyroidectomy) period of three severely hyperthyroid patients, two females and one male, with ages ranging from 13 to 38 years. All patients had grade III goiter, and only one had exophthalmos. The mean duration of goiter was 3.6 years. All of them were given preoperative treatment consisting of propylthiouracil (PTU) at 450-600 mg/day; iodone, 3 tablets daily and propranolol at 30-120 mg/day for one month. All of them had normalized preoperative thyroid function tests. In addition to the preoperative medications mentioned above, all three patients received radioactive iodine therapy before surgery. The first two patients received relatively low doses of 8.0 and 7.5 mCi of I-131 respectively. Unfortunately the first patient had supraventricular tachycardia (SVT), post skin cutting and the other one went into thyroid storm. The third patient who received a cumulative dose of 23.5 mCi of I-131 before surgery had an uneventful postoperative course. It is concluded that normalization of thyroid hormone parameters, especially free T4 is not sufficient for an uneventful and uncomplicated peri-thyroidectomy period in severely hyperthyroid patients with large goiters. Effective radioactive iodine therapy might prove to be helpful in inducing thyroid tissue fibrosis, thus leading to true clinical euthyroidism and excellent clinical course postoperatively. (author)

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.

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

Radioiodine treatment of hyperthyroidism

Becker, D.V.; Hurley, J.R.

Hyperthyroidism is a clinical symptom complex caused by elevated thyroid hormone levels. Of the disorders in which it appears, the most common is Graves' disease; toxic nodular goiter (Plummer's disease) is considerably less frequent. Recent studies suggest that Graves' disease is autoimmune in origin and is probably caused by a genetic defect in immunoserveillance in which thyroid-stimulating antibodies interact with thyroid-stimulating hormone (TSH) receptor sites on thyroid follicular cell membranes to increase synthesis and secretion of thyroid hormones. Toxic nodular goiter is characterized by the secretion of increased amounts of thyroid hormone by localized autonomous areas of increased function within the thyroid gland. Other forms of hyperthyroidism are discussed. Radioiodine treatment of hyperthyroidism is described

Full Text Available By prevalence among thyroid pathological conditions in Ukraine, the diffuse nontoxic goiter is dominated, the frequency of which, in addition to iodine deficiency, is influenced by anthropogenic pollution of environment. The article evaluated the role of the negative impact of polluted environment on the formation of thyroid disease in children from ecologically unfriendly region on the background of endemic iodine deficiency compared with children from ecologically friendly area of iodine deficiency. It has been determined the frequency of diffuse endemic goiter in children from studied groups according to palpation and ultrasonography. The functional state of the pituitary-thyroid system in children living in iodine deficiency environmentally unfriendly and ecologically friendly areas has been researched.

Objective: To analyze the common factors of ultrasonographic misdiagnosis of thyroid nodules. Methods: From 2006 to 2009, the pre-operative ultrasonographic diagnosis on 1933 patients with pathologically confirmed thyroid nodules were reviewed. Results: Of 2011 sonograms, ultrasonic diagnosis was corxect in 1575. The 436 diagnostic errors included false negative malignancy (133), false positive malignancy (37), and misdiagnosis between benign lesions (266). Conclusion: There were three main reasons of misdiagnosis including insufficient understanding of the high morbidity of nodular goiter and the relatively low incidence of thyroid adenoma; low awareness of the ultrasonographic diversity of nodular goiter and the sonographic characteristics of the thyroid adenoma and thyroid carcinoma; coexistence of underlying thyroid disease and multifocal nodules.

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

Experience of 1166 Thyroidectomy without Use of Prophylactic Antibiotic

Directory of Open Access Journals (Sweden)

Qiang Lu

2014-01-01

Full Text Available Background. Although the procedure requires a small surgical incision and a short duration, incision infection rate is very low in thyroidectomy; however, doctors still have misgivings about infection events. Aim. We retrospectively analyzed the prevention of incision infection without perioperative use of antibacterial medications following thyroidectomy. Materials and Methods. 1166 patients of thyroidectomy were not administered perioperative antibiotics. Unilateral total lobectomy or partial thyroidectomy was performed in 68.0% patients with single-side nodular goiter or thyroid adenoma. Bilateral partial thyroidectomy was performed in 25.5% patients with nodular goiter or Graves’ disease. The mean time of operation was 80.6 ± 4.87 (range: 25–390 min. Results. Resuturing was performed in two patients of secondary hemorrhage from residual thyroid following bilateral partial thyroidectomy. Temporally recurrent nerve paralysis was reported following right-side total lobectomy and left-side subtotal lobectomy in a nodular goiter patient. One case had suppurative infection in neck incision 5 days after bilateral partial thyroidectomy. Conclusions. Thyroidectomy, which is a clean incision, involves a small incision, short duration, and minor hemorrhage. If the operation is performed under strict conditions of sterility and hemostasis, antibacterial medications may not be required to prevent incision infection, which reduces cost and discourages the excessive use of antibiotics.

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

The fluorescence scintiscanning is a new method with minimal radiation exposure to show the distribution and quantification of stable iodine in the thyroid. In regions with high nutritional iodine supply (USA), the concentration of iodine-127 is, on an average, appr. 0.6 mg/g thyroid tissue. In normal persons in iodine-lacking regions it amounts to 0.38 mg/g and is even more reduced if there is an enthyreotic goiter (0.22 mg/g). A single administration of a high quantity of iodine by means of water-soluble contrast substances to adults with a healthy thyroid and to persons with an enthyreotic goiter does generally not cause an increase in the intrathyroidal iodine concentration; if a hyperthyreosis is indicated, however, high values are found and this might be useful for a differential diagnosis. Chronic iodine intake (non-water soluble contrast substances) leads to a slow increase in the intrathyreoidal iodine concentration. Fluorescence scintiscanning is here the method chosen to present the thyroid morphologically. Iodine substitution in low doses does not cause a significant increase in the iodine contents of the thyroid of adults. In children and juveniles, however, normal iodine concentrations in the thyroid tissue could be found substituting with 100 μg potassium iodide. Taking into consideration kinetic data of the iodine metabolism an iodine-'escape' of the false adapted 'older' goiter tissue must be assumed. (orig.) [de

Objective: To explore the treatment effects of individual 131 I dose treatment of Graves' disease. Methods: Graves' disease patients were given individual 131 I dose ( 131 I MBq/per gram thyroid tissue), which ranged at 1.48-4.07 MBq/g. A total of 1003 cases (76.9%) were successfully followed up. The mean administered dose of 131 I was (329.3 ± 307.1, 44.4-3700) MBq. The term of follow-up was (16.4 ± 10.0, 3.0-44.7) months. Results: After one dose 131 I treatment, 593 patients (59.1%) were with euthyroid, 200 patients (19.9%) hypothyroidism, 190 patients (18.9%) were partially remitted, 20 patients (2.0%) showed no changes; 259 patients (25.8%) suffered from early hypothyroidism, 88 patients were with transient hypothyroidism. Logistic stepwise regression analysis revealed that hard thyroid texture was a risk factor for developing early hypothyroidism, whereas large goiter was a protective factor for developing permanent hypothyroidism. Partial-correlations analysis showed that curative effects correlated negatively with the weight of goiter mass, the course of disease and the use of antithyroid drugs (ATD). After 131 I treatment, for 195 patients (41.7%) the ophthalmopathy was cured, 155 patients (33.1%) were partially remitted, 105 patients (22.4%) showed no effects, 13 patients (2.8%)were deteriorated. For 56 patients (77.8%) their hyperthyroid heart disease was cured, 10 patients(13.9%) were partially remitted, 6 patients (8.3%) were of no effects. For 60 patients (85.7%) periodic paralysis associated with thyrotoxicosis were cured, 2 patients (2.9%) were partially remitted, 8 patients (11.4%) were of no effects. Of 249 patients with large goiter (≥90 g), 219 cases (88.0%) were completely remitted. Conclusions: The individual 131 I dose treatment for Graves' disease exerts good therapeutic efficiencies. 131 I treatment for ophthalmopathy, hyperthyroid heart disease and Graves' disease with lager goiter is effective and safe.

Analytical ion microscopy (AIM) can be used for imaging and relative quantification of chemical elements in tissue sections. We used this technique to assess the changes in 127I mapping within thyroid follicular cells and follicular lumina in benign thyroid epithelial abnormalities from 17 patients and in macroscopically normal perinodular tissue surrounding solitary cold nodules from 8 patients. Among the 17 patients, 9 had simple goiters, 5 had toxic nodular goiters, and 3 had hypofunctioning (cold) nodules. The tissue samples were fixed chemically and embedded in methacrylate resin to ensure preservation of organified iodine, and thin sections were analyzed by AIM. 127I was found in the follicular lumina and follicular epithelial cells of most specimens. The local concentration of 127I, which is proportional to the ratio of the two secondary ion beam currents of iodine and carbon, was evaluated in 30 follicular lumina and 30 follicular epithelial cells of each specimen. In normal tissue, the relative 127I concentration within follicular cells (mean, 0.72; range 0.01-8.30) was much lower than that in follicular lumina (mean, 4.63; range, 0.18-36.74). In simple goiter tissue, follicular lumen (mean, 0.57; range, 0.00-5.76), and cell (mean, 0.17; range, 0.002-1.82) relative 127I concentrations were below normal, but both distributions remained different. On the contrary, in toxic nodular goiter tissue the follicular cell relative 127I concentration (mean, 0.96; range, 0.003-27.3) largely overlapped that of the follicular lumina (mean, 2.1; range, 0.001-36.5). The cold nodules had the lowest relative follicular lumina 127I concentration (mean, 0.008; range, undetectable-0.07), and the relative cellular 127I concentrations were undetectable in 67%. These results demonstrate the capacity of AIM to characterize the functional activity of thyroid tissue without prior administration of radio-iodine

Objective: To evaluate clinical symptoms, signs and various forms of thyrotoxicosis, and to assess the thyroid function status at the first 6-week follow-up. Methods: The retrospective chart review involved thyrotoxic patients presenting at the Endocrine Clinic of Jinnah Postgraduate Medical Centre, Karachi, between April 2007 and January 2011. All hyperthyroid patients were included with the exception of those with suspected or proven malignancy. The records were maintained on a structured proforma and analysed statistically to work out frequencies and percentages. Results: A total of 507 patients were included. Most common form of thyrotoxicosis was Graves disease, with diffuse toxic goiter affecting 269 (53%) patients; followed by toxic multinodular goiter in 102 (20.1%); solitary toxic nodule in 56 (11%); thyrotoxicosis without goiter in 44 (8.7%); subclinical hyperthyroidism in 22 (4.3.%); thyroiditis in 9 (1.8%); and thyrotoxicosis with solitary cold nodule in 4 (0.9%). The common presenting symptoms and signs were goiter (n=415; 85.7%), with eye signs present in 137 (27.7%) patients and heart failure in 20 (4.8%) patients. Of the 321 patients who attended the first six-week follow-up, 309 (94.4%) had their FT4 levels checked. Out of them, 130(42.1%) had euthyroid levels; 113 (36.6%) had lower but still toxic level; 36 (11.7%) had no change; and 30(9.7%) became hypothyroid. TSH levels at first follow-up remained suppressed in 211 (73%) patients; normal in 47(16.3%); and increased in 31 (10.7%). Conclusions: Graves disease was found to be the most common cause of hyperthyroidism. At first follow-up 10.4% of patients had become hypothyroid. Therefore the starting dose of antithyroid drugs was reduced in the clinic. Thyroid stimulating hormone assay was of little help in adjusting treatment at the 6-week follow-up, as almost all cases of hypothyroidism could have been picked up on FT4 assay alone. (author)

Riedel's thyroiditis (RT) is a rare disease characterized by a chronic inflammatory lesion of the thyroid gland with invasion by a dense fibrosis. Publications of the imaging features of RT are scarce. To our knowledge, ultrasound elastography (USE) findings have not been previously reported. Therefore, we describe two patients with RT who were imaged with ultrasonography (US), USE, and fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). Two women were referred for a large, hard goiter with compressive symptoms (dyspnea and dysphagia); in one patient, the goiter was associated with retroperitoneal fibrosis. In both cases, RT was confirmed by surgical biopsy with pathological examination. Thyroid US imaging was performed with a US scan and a 10-13 MHz linear transducer. The hardness of the tissues was analyzed using transient USE (ShearWave, Aixplorer-SuperSonic Imagine). PET/CT scanning was performed with a Philips Gemini GXL camera (GE Medical Systems). In the first patient, US examination revealed a compressive multinodular goiter with large solid hypoechoic and poorly vascularized areas adjacent to the nodules. The predominant right nodule was hypoechoic with irregular margins. The second patient had a hypoechoic goiter with large bilateral hypoechoic areas. In both cases, an unusual feature was observed: the presence of tissue surrounding the primitive carotid artery, associated with thrombi of the internal jugular vein. Further, USE showed heterogeneity in the stiffness values of the thyroid parenchyma varying between 21 kPa and 281 kPa. FDG-PET/CT imaging showed uptake foci in the thyroid gland. In both cases, US showed a decrease in the thyroid gland volume and the disappearance of encasement of the neck vasculature in response to corticosteroid treatment. In contrast, the FDG-PET/CT features remained unchanged. US features, such as vascular encasement and improvement under corticosteroid treatment, seem to be specific to this

Thyroid Stimulating Hormone Resistance Syndrome – A Case Report

Directory of Open Access Journals (Sweden)

SM Ashrafuzzaman

2014-01-01

Full Text Available Resistance to thyrotropin or thyroid stimulating hormone (RTSH can be defined as decreased responsiveness to thyroid stimulating hormone (TSH characterized by high TSH with normal but occasionally low T4 and T3 usually in absence of goiter or ectopic thyroid. It can be diagnosed when TSH is >30 mIU/L but free T4 (FT4 is within normal limit. Patient usually presents in euthyroid state with abnormally high TSH but may also present with mild to overt hypothyroidism. The precise prevalence is not known, but 20-30% infants may show transient mild RTSH. In adults it is rare. Here we report a case of RTSH in which a 19 years old young girl presented in euthyroid state with mild goiter. Ibrahim Med. Coll. J. 2014; 8(1: 32-33

Peculiarities of hypothalamic-pituitary thyroid function in children born from the Chornobyl NPP accident survivors

International Nuclear Information System (INIS)

Kopylova, O.V.; Stepanenko, O.A.

2015-01-01

The 168 children born to parents exposed after the Chernobyl accident were examined to study the hypothalamic-pituitary-thyroid system function in descendants of the Chernobyl survivors. Clinical, hormonal, ultrasound examinations and challenge test with tyroliberynum were conducted. Some abnormalities that might explain the functional strain of the hypothalamic-pituitary system were identified being of a great role in origination and progress of thyroid disease. The prolonged strain leads to decreased production of thyroid hormone, which causes an increased secretion of thyroid stimulating hormone. Under the influence of TSH the thyroid gland in the first stage becomes increased in its mass, which leads to the formation of endemic goiter. Stable and permanent thyroid gland enlargement often leads to formation of the nodular goiter and other proliferative processes, namely to carcinogenesis

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

The objectives of this study were to map the prevalence of goiter in Sudan and to study the etiological factors involved. A further objective was to explore the use of serum thyroglobulin (Tg) level in the assessment of endemic goiter. The survey took place in the period from June to November 2006. The survey covered nine cities including Nyala and Elfasher (Western part), Wau (in the South), Atbara and Dongula (in the north), Dmazine (South East), Port Sudan (Eastern part), Kosti and Khartoum (in the Centre ). Khartoum was divided into three different cities Khartoum, Khartoum North and Omdurman. The study included 6181 male and female schoolchildren at the age 6-12 years old. All the children were clinically examined for the presence of goiter using WHO palpation method. Blood samples were randomly collected from 360 children (30-37) from each selected city irrespective of their thyroid status or gender. Serum samples were analyzed for the concentration of T{sub 4}, T{sub 3}, TSH, and Tg. Casual urine samples were also collected from the same selected subjects. Urine samples were analyzed for iodine and thiocyanate concentrations. Water samples were collected from each school and analyzed for the concentration of Ca, Mg, Cl, F and total Hardness. The results indicated that the overall total goiter rate was 40.62%. The highest goiter rate was found in Kosti town (77.67%) and the lowest in Omdurman Khartoum state (12.22%). The overall median urinary iodine excretion (UIE) was 6.55 {mu}g/dl. Iodine deficiency was detected in 70.28% of the children and there were great variations in the median UIE from region to anther started from as low as 2.70{mu}g/d1 in Kosti town 46.40 {mu}g/d1 in Port Sudan city (at the cost of the Red Sed). The overall median concentration of urinary thiocyanate was 0.37 mg/d1. There were also variations in the median levels of urinary thiocyanate from city to another and slightly exceeded the cut off point (0.0.46 mg/d1) in pupils from Wau

Proton nuclear magnetic resonance (NMR) was used in a study of 40 patients with thyroid tumors following partial or total thyroidectomy. Three patient groups were considered: those with nodules showing increased uptake, those with solitary nodules with decreased uptake, and those with multinodular goiters. Spin-lattice and spin-spin relaxation times (T 1 and T 2 ) were measured on samples of nodular and extranodular tissue from each patient. Increased T 1 and T 2 were observed for benign cold nodules, an increase in T 1 alone for nodules with increased uptake, and a wide fluctuation in T 1 and T 2 for multinodular goiters. The four cancers in the series did not show a distinctive proton NMR pattern in comparison with the other nodular structures studied. The results point to the feasibility of applying NMR techniques to the detection of thyroid disease

Warthin-Finkeldey type giant cells were first described in autopsies performed on young children who died during the highly lethal measles epidemic in Palermo during the winter of 1908. The cells had 8-15 nuclei without identifiable cytoplasm within the germinal centers of lymphoid organs resembling megakaryocytes. We describe a case of Hashimoto thyroiditis with an enlarging substernal throid mass. The resection specimen contained many Warthin-Finkeldey-Like Cells (WFLC) in an extranodal marginal zone lymphoma (MALT type) with focal transformation to diffuse large B-cell lymphoma. The WFLC showed nuclear features similar to those of neighboring follicular dendritic cells (FDCs), favoring the hypothesis that these cells might be the product of fusion of FDCs. This is supported by immunostaining results and the occurrence of similar cells in follicular dendritic cell sarcomas and in "dysplastic" FDCs in hyaline vascular type Castleman disease, a possible precursor of follicular dendritic cell tumors.

In this article is evaluated the clinical and effectiveness of a simplified dosimetric approach to the iodine-131 treatment of hyperthyroidism due to Graves' disease or uninodular and multinodular toxic goiter. 189 patients with biochemically confirmed hyperthyroidism and performed thyroid ultrasonography and scintigraphy obtaining the diagnosis of Graves' disease in 43 patients, uninodular toxic goiter in 57 patients and multinodular toxic goiter in 89 patients were enrolled in order to be examined. It was found in 28 patients cold thyroid nodules and performed fine-needle aspiration with negative cytology for thyroid malignancy in all cases. Antithyroid drugs were stopped 5 days till radioiodine administration and, if necessary, restored 15 days after the treatment. Radioiodine uptake test was performed in all patients and therapeutic activity calculated to obtain a minimal activity of 185 MBq in the thyroid 24 hours after administration. The minimal activity was adjusted based on clinical, biochemical and imaging data to obtain a maximal activity of 370 MBq after 24 hours. Biochemical and clinical tests were scheduled at 3 and 12 months posttreatment and thyroxine treatment was started when hypothyroidism occurred. In Graves' disease patients a mean activity of 370 MBq (distribution 259-555 MBq) was administered. Three months after treatment and at least 15 days after methimazole discontinuation 32 of 43 (74%) patients were hypothyroid , 5 of 43 (11%) euthyroid and 6 of 43 (15%) hyperthyroid. Three of the latter were immediately submitted to a new radioiodine administration while 32 hypothyroid patients received thyroxine treatment. One year after the radioiodine treatment no patient had hyperthyroidism; 38 of 43 (89%) were on a replacement treatment while 5 (11%) remained euthyroid. In uni-and multinodular toxic goiter a mean activity of 444 MBq (distribution 259-555 MBq) was administered. Three months posttreatment 134 of 146 (92%) patients were euthyroid and

Full text: Objective: Evaluation of the response to therapy with fixed dose of Iodine-131 in patients with hyperthyroidism. One hundred seventeen patients with hyperthyroidism were tested and sent for treatment with Iodine-131. The dose of the therapy was calculated according to the pathology (Diffuser goiter (DG): Multinodular goiter (MNG) and Single toxic nodule (NST). Values of TSH confirmed hyperthyroidism by laboratory methods. The thyroid-blocking agents were discontinued: methimazole for five days and propylthiouracil two days prior to therapy. The pregnancy tests were routinely conducted in females of reproductive age group. Patients reported fasting for therapy. The doses were administered in capsule form after obtaining informed consent from the patients. The patients were normally instructed to eat only after two hours after administration of iodine to promote gastric absorption of the radionuclide. Normally a post therapy thyroid scan is performed four days after treatment. Patients are usually followed up by the endocrinologists. A three- month post therapy evaluation is done by the nuclear medicine physician by telephone. The demographic data of our patients treated are as follows: Total number of patients: 117 Female: 88 (75.21%) Male: 29 (24.79%) Age average: 45 years. Diffuse Goiter= 94 (80.34%), Multinodular Goiter= 17 (14.52%) and Toxic Adenoma (NST) = 6 (5.12%). The average administered dose was 22.5 mCi to DG, 41.8 mCi to MNG and 37.5 mCi to NST. 102 (87.14%) patients at the control at 2 years after treatment presented stable response to therapy, 15 (12.86%) required a second therapy, 11 (11.70%) with BD and 4 (23.52%) with BMN; and any patient with NST required a second therapy. 83 (88.29%) of the patients with BD; 13 (76.48%) with BMN and 6 (100%) with NST the therapy was successful. Conclusion: Fixed dose of I-131 in hyperthyroidism is useful in patients with DG (11.70%). In patients with MNG whom a fixed dose is supplied, 23.52% require a

Objective: To explore the clinical significance of changes of serum TRAb levels in patients with relapsing Graves' disease. Methods: Serum TRAb (with RRA) and several other thyroid-related hormones (TT 4 , TT 3 , TSH, FT 3 , with CLIA) were determined in the following subjects: 1. 25 cases of relapsing Graves' disease after previous successful treatment; 2. 18 cases of recently diagnosed Graves' disease; 3. 31 cases of successfully treated Graves' disease; 4. 15 cases of simple goiter; 5. 10 cases of nodular goiter; 6. 18 cases of hypothyroidism due to Hashimoto disease. Results: Positive rate of TRAb was 76.00% in patients with relapsing Graves' disease and 77.78% in recently diagnosed Graves' disease cases, both being significantly higher than that in all the other sets of patients studied (P<0.01). Conclusion: Determination of serum TRAb levels was helpful for the diagnosis of relapse in Graves' disease

Full Text Available Iodine deficiency disorders (IDDs have been recognized as one of the major nutritional disorders throughout the world affecting 200 million people who are at risk and another 71 million suffering from goiter and other IDDs. These groups of disorders can affect every stage of life, but most vulnerable age group is between 6 and 12 years and these disorders together constitute the single largest preventable cause of brain damage leading to learning disabilities and psychomotor impairment. The existence of endemic goiter in an extensive belt along the southern slopes of the Himalayas, Alps, and Andes has long been described, but consistently high prevalence of IDDs outside the endemic zones and failure to attain goals set by the National Iodine Deficiency Disorder Control Program questions the strategy and achievements till date. Therefore, the present article is an attempt to critically examine the program since inception in India.

The synthetic thyrotropin-releasing-hormone was stream-injected intravenously to 124 patients and 16 healthy people in doses of 200 μg. It was tolerated satisfactorily at the first and repeated injections. The radioimmunologic method was used prior to the test and 30 min after it to examine thyrotropin content in blood. In normal state the stimulation would result in 3.5-fold increase in thyrotropin level on the average. The hypophysial reserve of thyrotropin was significantly lower in cases of diffuse toxic goiter in grave and semigrave forms and toxic adenoma. It was significantly higher at primary hypothyrosis and retained at nodular euthyroid goiter, neupocirculatopy dystonia and mild thyrotoxicosis. At thyroid gland disturbances the test with thyrotropin-releasing-hormone is of diagnostic value at primary hypothyrosis in the initial latent period; besides, it can be used for control of substitution therapy and as a supplementary test at thyrotoxicosis

Follicular carcinoma of the thyroid in association with hyperthyroidism is rare. The malignant lesion may remain occult for a long time. Certain clinical and cytologic features may be helpful in raising the alarm. An elderly male with a history of occupational exposure to X rays, long-standing toxic multinodular goiter and clinical hyperthyroidism presented with a rapidly enlarging mass in the neck. Cytologic smears showed a prominent microfollicular pattern, scanty colloid, anisonucleosis and nuclear overlapping. The noteworthy feature was the presence of marginal vacuoles. The cytologic diagnosis of follicular neoplasm with highly suggestive malignancy was made. Subsequently, multiple pulmonary nodules provided radiologic evidence of possible metastatic spread. This case report demonstrates the rare association of follicular carcinoma of the thyroid with hyperthyroidism and analyzes certain high-risk clinical and cytologic features to be considered in the follow-up of long-standing hyperfunctioning multinodular goiter.

We have developed rat thyroid and mammary clonogen transplantation systems for the study of radiogenic cancer induction at the target cell level in vivo. The epithelial cell populations of both glands contain small subpopulations of cells which are capable of giving rise to monoclonal glandular structures when transplanted and stimulated with appropriate hormones. Previous results indicated that these clonogens are the precursor cells of radiogenic cancer, and that initiation, is common event at the clonegenic cell level. Detailed information on the physiologic control of clonogen proliferation, differentiation, and total numbers is thus essential to an understanding of the carcinogenic process. We report here studies on investigations on the relationships between grafted thyroid cell number and the rapidity and degree of reestablishment of the thyroid-hypothalamus-pituitary feedback axis in thyroidectomized rats maintained on a normal diet or an iodine deficient diet; studies of the persistence of, and the differentiation potential and functional characteristics of, the TSH-(thyrotropin-) responsive sub- population of clonogens during goitrogenesis, the plateau-phase of goiter growth, and goiter involution; studies of changes in the size of the clonogen sub-population during goitrogenesis, goiter involution and the response to goitrogen rechallenge; and a large carcinogenesis experiment on the nature of the grafted thyroid cell number-dependent suppression of promotion/progression to neoplasia in grafts of radiation-initiated thyroid cells. Data from these studies will be used in the design of future carcinogenesis experiments on neoplastic initiation by high and low LET radiations and on cell interactions during the neoplastic process

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.

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

Iodine is an essential component of the hormones produced by the thyroid gland that are essential for mammalian life. Although goiter is the most visible sequelae of iodine deficiency, the major impact of hypothyroidism as a result of iodine deficiency is impaired neurodevelopment, particularly early in life. According to the World Health Organization, it is the single most preventable cause of mental retardation and brain damage. The simplest, most effective and inexpensive preventive method is the consumption of iodized salt. The objective of the following study is to estimate the prevalence of goiter in children in the rural areas of Mysore and Coorg districts in India and estimate iodine levels in salt samples. A cross-sectional study in the age group of 6-12 years, using population proportionate to size systematic sampling method. The total sample size was 10,082: out of which 5337 was from Mysore and the rest from Coorg district. Clinical examination of the thyroid gland was done and salt samples collected for the estimation of Iodine. The total prevalence of goiter was 19.01% in children of 6-12 years in Coorg district and 8.77% in Mysore district and it was more in females than in males. It was observed that iodine deficiency disorders is endemic in both districts, with a prevalence of 19.01% in children aged 6-12 years in Coorg district and 8.77% in Mysore district. Analysis of salt samples suggested that most of the samples were inadequately iodised (73.92% in Coorg and 45.92% in Mysore).

We have developed rat thyroid and mammary clonogen transplantation systems for the study of radiogenic cancer induction at the target cell level in vivo. The epithelial cell populations of both glands contain small subpopulations of cells which are capable of giving rise to monoclonal glandular structures when transplanted and stimulated with appropriate hormones. During the end of the last grant year and the first half of the current grant year, we have completed analyses and summarized for publication: investigations on the relationship between grafted thyroid cell number and the rapidity and degree of reestablishment of the thyroid-hypothalamicpituitary axis in thyroidectomized rats maintained on a normal diet or an iodine deficient diet; studies of the persistence of, and the differentiation potential and functional characteristics of, the TSH- (thyrotropin-) responsive sub-population of clonogens during goitrogenesis, the plateau-phase of goiter growth, and goiter involution; studies of changes in the size of the clonogen sub-population during goitrogenesis, goiter involution and the response to goitrogen rechallenge; and the results of the large carcinogenesis experiment on the nature of the grafted thyroid cell number-dependent suppression of promotion/progression to neoplasia in grafts of radiation-initiated thyroid cells. We are testing new techniques for the culture, cytofluorescent analysis and characterization mammary epithelial cells and of clonogens in a parallel project, and plan to apply similar technology to the thyroid epithelial cells and clonogen population. Data from these studies will be used in the design of future carcinogenesis experiments on neoplastic initiation by high and low LET radiations and on cells interactions during the neoplastic process

Childhood thyromegaly: recent developments

Evaluation of a child with goiter includes historical review, physical examination, and measurement of serum concentrations of PBI, T4 and T3RU, TSH, and titers of antithyroglobulin and antithyroid microsomal antibodies. If there are no indications for more intensive evaluation such as history of cervical irradiation, a palpable abnormality of the thyroid gland or unusual laboratory findings (e.g., a significant PBI-thyroxine iodine discrepancy in the absence of a positive antithyroid antibody titer), a trial of TSH-suppressive therapy with thyroxine is undertake, even if the cause of thyromegaly has not been identified. If thyroid size diminishes in the ensuing six to 12 months, treatment is maintained for approximately two years and then discontinued. If the goiter recurs, or if there is impaired thyroid function, treatment is resumed. Periodically, antithyroid antibody titers and indices of thyroid function are determined. If the goiter does not diminish after a reasonable trial of suppressive therapy with adequate amounts of thyroxine (i.e., those quantities which will inhibit TRH-induced secretion of TSH), subtotal thyroidectomy is recommended to be certain that an underlying neoplasm has not been overlooked. A biopsy of the thyroid is not performed routinely in such children prior to operative therapy. Almost invariably, examination of the surgical specimen reveals CLT. Postoperatively, suppressive doses of thyroxine are maintained indefinitely. Inasmuch as thyroxine suppression of TSH secretion is essential in the management of patients with thyroid neoplasms, a limited medical trial, as described, does not place the patient at undue risk

Graves' disease and toxic nodular goiter - radioiodine therapy

International Nuclear Information System (INIS)

Schicha, H.; Dietlein, M.

2002-01-01

At the 15th conference on the human thyroid in Heidelberg in 2001 the following aspects of the radioiodine therapy of benign thyroid disorders were presented: General strategies for therapy of benign thyroid diseases, criterions for conservative or definitive treatment of hyperthyroidism as first line therapy and finally preparation, procedural details, results, side effects, costs and follow-up care of radioiodine therapy as well as legal guidelines for hospitalization in Germany. The diagnosis Graves' hyperthyroidism needs the decision, if rather a conservative treatment or if primary radioiodine therapy is the best therapeutic approach. In the USA 70-90% of these patients are treated with radioiodine as first line therapy, whereas in Germany the conservative therapy for 1-1.5 years is recommended for 90%. This review describes subgroups of patients with Graves' disease showing a higher probability to relapse after conservative treatment. Comparing benefits, adverse effects, costs, and conveniences of both treatment strategies the authors conclude that radioiodine therapy should be preferred as first line therapy in 60-70% of the patients with Graves' hyperthyroidism.

Several patients were identified with dyshormonogenesis caused by mutations in the thyroglobulin (TG) gene. These defects are inherited in an autosomal recessive manner and affected individuals are either homozygous or compound heterozygous for the mutations. The aim of the present study was to identify new TG mutations in a patient of Vietnamese origin affected by congenital hypothyroidism, goiter and low levels of serum TG. DNA sequencing identified the presence of compound heterozygous mutations in the TG gene: the maternal mutation consists of a novel c.745+1G>A (g.IVS6 + 1G>A), whereas the hypothetical paternal mutation consists of a novel c.7036+2T>A (g.IVS40 + 2T>A). The father was not available for segregation analysis. Ex-vivo splicing assays and subsequent RT-PCR analyses were performed on mRNA isolated from the eukaryotic-cells transfected with normal and mutant expression vectors. Minigene analysis of the c.745+1G>A mutant showed that the exon 6 is skipped during pre-mRNA splicing or partially included by use of a cryptic 5' splice site located to 55 nucleotides upstream of the authentic exon 6/intron 6 junction site. The functional analysis of c.7036+2T>A mutation showed a complete skipping of exon 40. The theoretical consequences of splice site mutations, predicted with the bioinformatics tool NNSplice, Fsplice, SPL, SPLM and MaxEntScan programs were investigated and evaluated in relation with the experimental evidence. These analyses predicted that both mutant alleles would result in the abolition of the authentic splice donor sites. The c.745+1G>A mutation originates two putative truncated proteins of 200 and 1142 amino acids, whereas c.7036+2T>A mutation results in a putative truncated protein of 2277 amino acids. In conclusion, we show that the c.745+1G>A mutation promotes the activation of a new cryptic donor splice site in the exon 6 of the TG gene. The functional consequences of these mutations could be structural changes in the protein

High relative frequency of thyroid papillary carcinoma in northern Portugal.

Science.gov (United States)

Sambade, M C; Gonçalves, V S; Dias, M; Sobrinho-Simões, M A

1983-05-01

Two hundred and twelve papillary and 40 follicular carcinomas were found in 3002 thyroid glands examined from 1931 to 1975 in four Laboratories of Pathology that fairly cover northern Portugal. There was a striking preponderance of women both in papillary (female:male = 6.9:1) and follicular carcinoma (5.7:1). Sex-specific frequency of malignancy was significantly greater in men (13.3%) than in women (8.8%). The overall papillary/follicular ratio was 5.3:1 and did not significantly change throughout the study period. Papillary/follicular ratio was not significantly greater in litoral (5.5:1) than in regions with a low iodine intake and a relatively high prevalence of goiter (3.5:1). It is advanced that this high relative frequency of papillary carcinoma in northern Portugal, even in goiter areas, may reflect the existence of a racial factor since there is not enough evidence to support the influence of dietary iodine, previous irradiation and concurrent thyroiditis.

Radio-contrast agent-induced hyperthyroidism: case report and review of the literature

2016-01-01

A 66 year-old woman with a history of a euthyroid multinodular goiter underwent a head and neck computed tomography (CT) scan (total iodine load of 35 g) in order to evaluate the extent of retrosternal expansion. Less than 24 h after the iodine-based contrast media (ICM) administration, she presented with symptoms and laboratory findings typical of thyrotoxicosis. She was treated successfully with antithyroid medications. This is the shortest time reported in the literature and it is of clinical importance, as it may have an impact to the recommendations given by the attending physician. Given the fact that a large number of ICM examinations are performed in everyday practice, physicians should be aware of this possible thyroid-specific effect. Prophylactic drugs could be considered in high-risk populations, such as administration of perchlorate and a thionamide class drug to elderly patients with suppressed TSH and/or palpable goiter, started the day before and continued for two weeks after ICM administration.

For more than one decade it began to be used the 131 I in patient with goiters sporadic eufuncionantes, aspect in that one needs to continue working, because the clinical answer in general showed that the nodules didn't always change size. It is to establish the dose to administer, while the risk exists of developing hypothyroidism, as well as the possibility to have to carry out a surgery of the thyroid for nodular growth after receiving the 131 I. The future of the 131 I is promissory, not alone as measure therapy but also as diagnostic method, because they are to solve relative multiple queries to the indications, the factors that influence in the answer, dose calculation, the patients' selection and long term absence of random studies that allow to define in the treatment of the non toxic goiter the advantages of the use of the levotiroxina, of the surgery or of the 131 I

The goiter prevalence in iodine-deficient regions is up to 25%-54%. The most frequent disease in these endemic areas is non-toxic goiter, which is, however, oftentimes connected with autonomously functioning thyroid tissue leading to borderline or overt hyperthyroidism. Other thyroid diseases like cancer, thyroiditis and hypothyroidism play only a miner role in a thyroid clinic, while cases of Graves' disease may be observed more frequently. The most cost-effective tools to evaluate thyroid patients are the hand, ear and mouth of the thyroid clinician. The differential diagnosis of thyroid disorders may be evaluated by a battery of diagnostic tools like in-vitro tests and high performance imaging modalities. Once the diagnosis is established, the appropriate therapeutic procedures (drugs, radioiodine, surgery) have to be chosen. This review should be considered as a guideline for the diagnosis and treatment of thyroid diseases. In addition, special problems concerning elderly patients and pregnant women are discussed, including the differential diagnosis of thyroid diseases. (orig.).

The history of radioiodine therapy beginnings

2016-03-01

Full Text Available This report contains historical review of radioiodine therapy invention and clinical implementation for the treatment of patients with diffuse toxic goiter and differentiated thyroid cancer. In 1923 Henry Plummer has strongly recommended to prescribe stable iodine in patients with Grave’s diseases after surgery in order to prevent thyrotoxic storm. Radioactive isotopes of iodine for the first time were obtained by Enrico Fermi in 1934 in laboratory. Clinical implementation of radioiodine was started in 40th years of past century. In 1940 experimentally have been shown that thyroid gland with Grave’s disease accumulated as much as 80% of radioiodine administered activity. Saul Hertz was the first physician who used radioactive iodine in January, 1941 with purpose to treat diffuse toxic goiter patients. Samuel Seidlin was first who used radioiodine in March, 1943 to treat patient with functioned differentiated thyroid cancer metastases. In Russia radioiodine treatment of patients started since 1982 in Medical Radiological Research Centre (former Institute of Medical Radiology, Obninsk.

Endogenous subclinical hyperthyroidism and cardiovascular system: time to reconsider?

Science.gov (United States)

Patanè, Salvatore; Marte, Filippo; Sturiale, Mauro

2011-05-19

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. Exogenous sublinical hyperthyroidism is a thyroid metabolic state caused by L-thyroxine administration. Endogenous subclinical hyperthyroidism is a thyroid metabolic state in patients with autonomously functioning thyroid nodule or multinodular goiter, various forms of thyroiditis, in areas with endemic goiter and particularly in elderly subjects. Endogenous subclinical hyperthyroidism is currently the subject of numerous studies and it yet remains controversial particularly as it relates to its treatment and to cardiovascular impact nevertheless established effects have been demonstrated. Recently, acute myocardial infarction without significant coronary stenoses and recurrent acute pulmonary embolism have been reported associated with subclinical hyperthyroidism without L-thyroxine administration. So, it is very important to recognize and to treat promptly also endogenous subclinical hyperthyroidism. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

This study was planned to investigate serum concentration of free thyroxin (FT/sub 4/) and thyroid stimulating hormone (TSH) as well as thyroid dysfunctions in children attending CENUM, Mayo Hospital Lahore. A total of 227 children (131 female and 96 male) were selected for this study. Their age range was 1 to 12 years (mean 7.6 +- 3.4 years). 45 (19.8%) children had goiter with significantly more frequency in female as compared to male children (28.2% V s 8.3%; p<0.05). More than 70% of the children had F/sub 4/ and TSH within their respective normal ranges (euthyroid). Thyroid dysfunctions were detected in 11.0% children (7.5% hypothyroidism; 3.5% hyperthyroidism). Only the incidence of hyperthyroidism was significantly more in goiterous children. There was no significant difference in the incidence of hyperthyroidism but hypothyroidism was significant (p<0.05) more common in female children. (author)

The condition of thyroid was examined in 2188 Chernobyl clean-up workers residing in Latvia and a control group consisting of 1041 employees of the Ministry of International Affairs. Thyroid examinations included palpation, ultrasonography, selective scintigraphy and detection of the level of thyroid hormones in blood serum:L STH (thyroid-stimulating hormone), total T3 (triiodothyronine), and T4 (thyroxine). Thyroid was registered in 394 Chernobyl clean-up workers. Of these cases, 28 patients with suspected thyroid cancer were operated, and morphological examinations revealed papillary adenocarcinoma (in 5 patients), follicular adenocarcinoma (2), nodular colloid goiter (16); toxic diffuse goiter (1), papillary-follicular adenoma (3), and chronic thyroiditis (1). It was determined that the thyroid pathology in the Chernobyl clean-up workers had a tendency to progress (27 cases in 1987 versus 394 cases in 1998 in total; and absence of thyroid cancer in 1987, compared with 7 cases in 1998); thyroid nodules increased twice (64 cases in 1997, compare with 126 cases in 1998).

2017-10-01

Iodine deficiency is one of the most important health problems worldwide. The overall aim of this study was a narrative review of the past and present status of iodine nutrition in the Iranian population to gather and provide valuable background data in this field for future studies. For this narrative literature review study, published internal (SID, Iran doc, Iran medex) and international (Web of knowledge, Pubmed, SCOPUS) source studies were searched using the following medical subject heading terms: Iodine, IDD (iodine deficiency disorders), UIC (urinary iodine concentration), Goiter, IQ (intelligence quotient), thyroid hormone, Iodine and pregnancy, Iodine and breast feeding, as well as Iodized salt, reporting the prevalence of iodine deficiency and iodine nutrition status of different target populations in Iran over 25 years, between 1988 - 2014, were assessed. We found 185 abstracts by literature search, of which, 161 papers that were as case reports, animal study, with lack of regional or national data were excluded after full text evaluation. Finally 24 full papers covering regional or national data on iodine nutrition of the study population were eligible for our review. Iodine deficiency, as a nutritional problem, had been identified in Iran since 1968. In the years 1987 - 1989, a few studies were done to define the prevalence of iodine deficiency in the country. The first nation-wide survey was performed in 14 provinces. Based on this survey all provinces were suffering of endemic goiter. In 1989, iodine deficiency was recognized as a major problem for community health. In 1990, salt factories began to produce iodized salt and in 1996, the second national survey was performed in 26 provinces. This survey indicated that 40% of boys and 50% of girls have goiter, with a median urinary iodine excretion of 205 µg/L. The 3rd national survey in 2001 showed that the total goiter rate is 9.8% and median UIC of 165 μg/L. In 2007, the 3th national survey was

The aim of the this study was to evaluate different states in hyperthyroid patients and incidence of hypothyroidism after I-131 therapy.We observed a total of 184 hyperthyroid pts, from which 108(58,7%)pts with Graves' disease,65(35,3%)pts with single toxicum nodule and 11(6%)pts with toxicum multinodular goitre,treated with radioiodine therapy during the period 1986-2001.Dose of I-131 orally administered ranged 150-1100MBq and was calculated according to the 'MBq/gram' method.The radioiodine-131 therapy was performed once in 69,5%(128/184)pts,twice in 21,2%(39/184)pts and in 9,3%(17/184)pts more than two doses. Completely cured of hyperthyroidism occurred in 61%(66/108)pts with Graves' disease,81,8%(9/11)pts with toxic multinodular goiter and 90,7%(59/65)pts with single toxic nodule. The patients in our study were evaluated 6 months to 15 years after received J-131 therapy. Incidence of early hypothyroidism within one year was 23,1%(25/108) in Graves' disease,9%(1/11) in toxic multinodular goiter and 4,6%(3/65) with single toxicum nodule.Overall incidence of hypothyroidism within one year was 17,6% and had cumulative increase of Graves' disease every following year approximately for 3%,while for adenoma toxicum there was no any significant changes. We concluded that radioiodine therapy is simple,comfortable radical method for medical treatment of hyperthyroidism and indicate higher incidence of hypothyroidism in patients treated with I-131 for Graves' disease than that of patients treated for toxicum multinodular goiters and single toxic nodule

Subclinical hypothyroidism can be defined as an asymptomatic state in which a reduction in thyroid activity has been compensated by an increased TSH output to maintain an euthyroid state. We analysed clinical features, laboratory data, and pathologic findings in 39 cases of subclinical hypothyroidism who were diagnosed at the Dept. of Internal Medicine, Chungnam National University Hospital from Aug. 1984 to June, 1985. 1) The age distribution was from sixteen to sixty-nine and mean age was 34.8. Peak incidence was in the 4th decade and 3rd, 5th, 6th decade in order. 2) The sex distribution showed female preponderance with a ratio of 18.5 to 1. 3) The major presenting manifestations were nonspecific ones such as fatigue, indigestion, and anorexia. 4) Physical examination revealed diffuse goiter in 47.6%. Major abnormalities were no gross abnormality (30.9%), nodular goiter and facial edema. 5) There was no significant difference of the basal serum T3 and T4 concentrations between subclinical hypothyroidism and normal controls (p>0.05). 6) The basal serum TSH concentration of subclinical hypothyroidism (32.61±14.95 μU/ml) was significantly higher than that of normal controls (3.92±1.05 μU/ml) (p<0.005). 7) Microsomal antibody was detected in 80.6% and thyroglobulin antibody was detected in 30%. 8) The pathologic findings in 26 cases revealed Hashimoto's thyroiditis in 76.9% (lymphocytic type, 34.6%; oxyphilic type, 26.9%; fibrotic type, 15.4%). The others were adenomatous goiter (15.4%), adenomatous carcinoma (3.8%) and subacute thyroiditis (3.8%).

Full Text Available Introduction: Iodine is an essential component of the hormones produced by the thyroid gland that are essential for mammalian life. Although goiter is the most visible sequelae of iodine deficiency, the major impact of hypothyroidism as a result of iodine deficiency is impaired neurodevelopment, particularly early in life. According to the World Health Organization, it is the single most preventable cause of mental retardation and brain damage. The simplest, most effective and inexpensive preventive method is the consumption of iodized salt. Objectives: The objective of the following study is to estimate the prevalence of goiter in children in the rural areas of Mysore and Coorg districts in India and estimate iodine levels in salt samples. Materials and Methods: A cross-sectional study in the age group of 6-12 years, using population proportionate to size systematic sampling method. The total sample size was 10,082: out of which 5337 was from Mysore and the rest from Coorg district. Clinical examination of the thyroid gland was done and salt samples collected for the estimation of Iodine. Results: The total prevalence of goiter was 19.01% in children of 6-12 years in Coorg district and 8.77% in Mysore district and it was more in females than in males. Conclusions: It was observed that iodine deficiency disorders is endemic in both districts, with a prevalence of 19.01% in children aged 6-12 years in Coorg district and 8.77% in Mysore district. Analysis of salt samples suggested that most of the samples were inadequately iodised (73.92% in Coorg and 45.92% in Mysore.

On the cells of origin of radiogenic thyroid cancer: New studies based on an old idea

We have presented evidence that the functional thyroid follicles (follicular units, FU) which are formed in grafts of monodispersed rat thyroid cells, and hence the thyroid tumors which later develop in such grafts, are clonal in origin. Recent studies have been designed to investigate: whether cell number-dependent inhibition of promotion-progression is mediated by remote hormonal feed-back, local cell-cell interactions, or both; the cell population kinetics of the clonogen subpopulation during goitrogenesis and goiter involution; and the effect of prolonged exposure to high levels of TSH (thyrotropin) on the capacity of the clonogens to give rise to functional FU. The results indicate that local cell-cell interactions play an important role in the cell number-dependent suppression of neoplastic promotion-progression. They also show that if sufficient thyroid cells are grafted, the thyroid-pituitary axis can be reestablished in thyroidectomized rats fed normal diets. In such animals given iodine deficient diets, the FU that develop in the thyroid grafts shift their secretory pattern to increase the ratio of T3 (triiodothyronine) to T4 (thyroxine), and thus conserve the available iodine. Finally, the clonogenic subpopulation is conserved during both goitrogenesis and goiter involution. When they are transplanted to thyroidectomized recipients, clonogens from two types of goiters form FU that are morphologically indistinguishable from those that develop in grafts of normal thyroid clonogens. Furthermore, the secretion of T3 and T4 by such grafts is dependent on the grafted clonogen number, and hence FU formation, and not on the total number of thyroid cells transplanted. We conclude that the thyroid clonogens, the presumptive cancer progenitor cells, have many of the characteristics of stem cells

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

Possibilities of 99mTc-MIBI for imaging of the thyroid parenchyma

1998-01-01

Thyroid parenchyma imaging is very important as an evidence of residual part of the gland in case of thyroidectomy. The determination of the mass of this part and its function is crucial at the substituting hormonal therapy. Also at cases of thyroid carcinomas the differential diagnosis of recurrences of radiation and/or postoperative fibrosis is difficult. The thyroid imaging by 131 I and by 99m Tc-pertechnetates is not always possible because of gland blockage from medicines, thyroid hormones and foods with high iodine content. The aim of this study was to establish if 99m Tc-MIBI could depict the thyroid parenchyma without being influenced by gland blockage giving a real image of it. A comparative scintigraphic study has been carried out at 58 patients with different thyroid diseases using 99m Tc-pertechnetate, 131 I and 99m Tc-MIBI. There were 17 patients with diffuse goiter, 27 with nodules (23 of normal activity and 4 with cold nodules), 3 patients with retrosternal goiter and 11 with thyroid carcinoma after surgery intervention. The visualization of the thyroid parenchyma with 99m Tc-MIBI was better than that with 99 0 m Tc-pertechnetate and no dependent on suppression of the gland. All nodules showed 99m Tc-MIBI uptake with the same intensity as the surrounding normal gland tissue. The scintigraphy with 99m Tc-MIBI was of no value for differential diagnosis of nodules. 99m Tc-MIBI scintigraphy could be successfully applied at patients with retrosternal thyroid goiter and for detecting a thyroid rest at patients with thyroid cancer after surgery intervention.

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.

Although the Nuss procedure for pectus excavatum is widely employed, a variety of complications have been reported with relatively high frequency; those that involve cardiac and pericardial injuries can be life threatening. To reduce such dangers, we present here a newly developed sternal elevator. The elevator is horseshoe shaped. Its elevator side has the same curvature as a Nuss introducer, so that interference between devices is minimal and no extra skin incision is needed for the elevator insertion. The elevator holds the sternum forward and enlarges the retrosternal space for safer passage of thoracoscopically guided introducer. The authors have used the elevator for 61 pectus excavatum cases between March 2004 and December 2009 without any major complications. The entire process of substernal tunneling was endoscopically observed, which eliminated any blunt and blind dissection, even in a significantly depressed funnel chest case. With the device, the sternum was effectively elevated again for the placement of the second plate in 30 cases. Our newly developed sternum elevator makes the Nuss procedure safer and more affordable without introducing any extra scarring.

A Rare Case of Esophageal Dysphagia in Children: Aberrant Right Subclavian Artery

Directory of Open Access Journals (Sweden)

Claudia Barone

2016-01-01

Full Text Available Dysphagia is an impairment of swallowing that may involve any structures from the mouth to the stomach. Esophageal dysphagia presents with the sensation of food sticking, pain with swallowing, substernal pressure, or chronic heartburn. There are many causes of esophageal dysphagia, such as motility disorders and mechanical and inflammatory diseases. Infrequently dysphagia arises from extrinsic compression of the esophagus from any vascular anomaly of the aortic arch. The most common embryologic abnormality of the aortic arch is aberrant right subclavian artery, clinically known as arteria lusoria. This abnormality is usually silent. Here, we report a case of six-year-old child presenting to us with a history of progressive dysphagia without respiratory symptoms. A barium esophagogram showed an increase of the physiological esophageal narrowing at the level of aortic arch, while at esophagogastroduodenoscopy there was an extrinsic pulsatile compression of the posterior portion of the esophagus suggesting an extrinsic compression by an aberrant vessel. Angio-CT (computed tomography scan confirmed the presence of an aberrant right subclavian artery.

We investigated, at diagnosis, the relationship between serum immunoglobulin G4 levels and the main characteristics of Graves' disease: hyperthyroidism severity, goiter size, presence of active Graves' ophthalmopathy, antithyroid antibodies status, and titer. This prospective study included 80 newly diagnosed Graves' disease patients. The main parameters measured at diagnosis: thyroid-stimulating hormone, free thyroxine, free triiodothyronine, total triiodothyronine, thyroglobulin, antithyroid peroxidase antibodies, anti-thyroglobulin antibodies, thyroid-stimulating hormone receptor antibodies, immunoglobulin G4. In Graves' disease patients, serum immunoglobulin G4 levels were higher than in general population (p = 0.028) and higher in men compared to women (p = 0.002). Only one female patient with intense hypoechoic goiter, high anti-thyroglobulin antibody, and antithyroid peroxidase antibody titers had an elevated serum immunoglobulin G4 level at diagnosis. Patients with immunoglobulin G4 levels above the 75th percentile (>237.52 mg/dl, N = 20) were younger at Graves' ophthalmopathy onset (p 286.28 mg/dl, N = 8) had lower total triiodothyronine values (p = 0.001) than patients with IgG below the 90th percentile. No significant correlations were found between smoking status (p = 0.58), goiter size (p = 0.50), the presence of ophthalmopathy (p = 0.42) or thyroid-stimulating hormone receptor antibody titers (p = 0.45) and the mean value of immunoglobulin G4 levels at diagnosis. Our data suggest that Graves' disease patients with elevated immunoglobulin G4 levels at diagnosis have a phenotype characterized by higher anti-thyroglobulin antibody and antithyroid peroxidase antibody titers, less severe T3 hyperthyroidism, younger age at ophthalmopathy onset and require a shorter duration of the first methimazole treatment cycle.

The aim of this study was to analyse the thyroid scintigraphy (TS) findings in 279 newborn with neonatal TSH (TSHnn) levels above 20 uUI/ml, detected in the national program of newborn screening of CH and phenylketonuria, and to compare them with: 1) final diagnosis, estimating its positive (PPV) and negative predictive value (NPV) and 2) TSHnn levels. Materials and Method: Thyroid scintigraphy of 279 newborn (57.3% girls) who presented TSHnn levels > 20 uUI/ml were revised, classifying them in eutopic gland (EuG), ectopic gland (EcG) and absence of contrast (AC). EuG was classified by visual and quantitative criteria in: normal contrast and size, goiter, and decreased contrast (DC). Tc99m-pertechnetate TS was performed average at 19th life's day (SD:11 days) with a gammacamera- computer system. The patients were separated according to hormonal confirmatory levels in: CH, hyperthyrotropinaemia (HT) and euthyroid. We compared TS results with final diagnosis and also with TSHnn levels (>= or 50 uUI/ml group (p<0.001). Moreover, the former group presented bigger proportion of CH newborns and of EcG scans than < 50uUI/ml patients (p<0.001). EcG and goiter condition had a PPV for CH of 100% and 79.6%, respectively. The NPV of normal TS was 86.7%. Conclusion: 1) Newborns with TSHnn levels larger than 20 uUI/ml show a high frequency of abnormal TS. 2) The EcG is highly predictive of CH. 3) Goiter and AC associated to TSHnn levels above 50 uUI/ml support strongly CH diagnosis. 4) Normal TS correspond very likely to euthyroid newborn, specially when TSHnn is lower than 50 uUI/ml

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

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

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

Autonomy and hyperthyroidism

International Nuclear Information System (INIS)

Emrich, D.; Schicha, H.; Baehre, M.

1986-01-01

The significance of autonomy in iodine-deficiency goiter for the development of hyperthyroidism was investigated. (1) In 171 of 426 consecutive patients high-resolution quantitative scintiscans showed signs suggestive of autonomy. With increasing 99mTc uptake by the thyroid their TT3 levels were found to rise progressively during suppression, while their pre-suppression TSH levels dropped progressively. This suggests global sup(99m)Tc uptake by the thyroid during suppression to be a useful indicator of the functional significance of autonomy. (2) Based on 326 patients with hyperthyroidism a system for differentiating between autonomy-related and immunogenic disease was developed and validated prospectively in another 162 patients with hyperthyroidism by assaying for thyroid stimulating antibodies (TSAb). TSAb was found to be present in 82% of the 77 patients diagnosed as having immunogenic hyperthyroidism and in only 8% of the 85 patients with autonomy-related hyperthyroidism. Our results support the assumption that autonomy in iodine-deficiency goiter plays a major role in the development of hyperthyroidism, while autoimmune processes appear to be of secondary importance.

To evaluate the long-term results of 131 I therapy for children, the course of 87 patients (three to 18 years old, 24 boys and 63 girls) treated from 1949 through 1968, for hyperthyroidism due to Graves's disease was studied. Dose of 131 I per patient ranged from 2.9 to 31 mCi (mean +- S. D., 9.75 +- 6.5). Patients were followed for five to 24 years (mean, 12.3 +- 3.5). Hyperthyroidism was controlled in 85 within one to 14 months (mean, 3.3 +- 2.6). Recurrence of thyrotoxicosis due to toxic diffuse goiter, observed in only one case after 11 years, was successfully re-treated with 131 I. Reproductive history and health status of the progeny of 131 I-treated patients were not different from those of the general population. No deaths and no cancer or leukemia were observed in patients or their offspring. The major cause of goiter regrowth was Hashimoto's thyroiditis. Hypothyroidism developed in 35 of 76 patients (46 percent). 131 I deserves further use in treatment of hyperthyroid children with Graves's disease

Objective: The only method of laboratory diagnosis for autoimmune thyroid diseases used to be serum TGA and TMA detections. Morerecently, quantitative analysis of TPOAb has been introduced. To assess the relative sensitivity of these tests , positive rates detected with the respective tests were compared. Methods: Serum TGA, TMA (with RIA) and TPOAb (with chemiluminescence enzyme immunoassay) were simultaneously detected in 998 cases of thyroid diseases (hyperthyroidism 307, Hashimoto's disease 193, simple goiter 498). For complementary sake, fine needle aspiration cytology was obtained in a number of cases including all the patients with Hashimoto's disease. Results: Positive detection rate of TPOAb in three groups of patients (hyperthyroidism, Hashimoto's, simple goiter) was 81.76%, 96.89 % and 42.97% respectively. With TMA, the positive rate was only 54.72%, 65.80%, 22.09% respectively. About one third more cases would be detected with the newer method. Conclusion: For the laboratory detection of auto immune thyroid diseases, quantitative analysis of TPOAb is much wore sensitive than the conventional TMA detection. (authors)

This study aimed to evaluate the ultrasonographic pattern of cervical lymph nodes (CLNs) and whether levothyroxine with prednisone therapy is effective for lymphadenopathy in patients with Hashimoto thyroiditis (HT). This retrospective study was looking at patients with confirmed diagnosis of HT who underwent comprehensive neck ultrasound examination. We reviewed sonographic findings in 127 patients with HT, 234 euthyroid patients with goiter, and 122 healthy subjects. In addition, 30 untreated HT patients with cervical lymphadenopathy were recruited for the levothyroxine with prednisone therapy. We rescanned the patients 9 months after treatment with levothyroxine and prednisone. Patients with HT had a higher rate of CLN detection on ultrasound than euthyroid patients with goiter and healthy subjects at cervical levels III, IV, and VI (P thyroid volume, thyroid nodule volume, CLN volume, symptom score, and cosmetic grade of 30 HT patients were remarkably decreased (P Hashimoto thyroiditis seems to be associated with an increased rate of detection of CLNs with abnormal sonographic features, particularly at cervical levels III, IV, and VI. Therapy with levothyroxine with prednisone is effective for cervical lymphadenopathy in patients with HT.

To asses the accuracy achieved by the A.C.A.T. and other clinical and laboratorial criterion in the diagnoses of T.A.I.B. we investigated twenty patients with goiter and antimicrossomal antibodies titres of 1/1.600 or more. Analysing the parameters useful in the diagnosis, we found a significant correlation between the antimicrossomal antibodies titres and the basal TSH concentration, an elevated basal TSH and an exaggerated response to TRH independent of the patient clinical status reflecting in the majority of the cases a state of subclinical hypotyroidism; an irregular appearance of the radioisotope thyroid scan and a positive response to a perchlorate discharge test. We conclude that from the parameters useful in the T.A.I.B. diagnosis, the A.C.A.T. detection mainly the antimicrossomal antibodies, is an excellent tool to detect patients with a clinical suspect of thyroid auto-immune disease and when we found high tires in a patient with goiter and an elevated basal TSH concentration we can suggest T.A.I.B. diagnosis.

This study aimed to evaluate 8-OHdG and hypoxia-inducible factor 1 (HIF-1α) levels in patients with hypoactive thyroid nodules (toxic multi-nodular goiter, Graves' disease, and Hashimoto's thyroiditis), as these parameters may be related to oxidative stress and the pathogenesis of cancer. The study included patients diagnosed with Graves' disease (n = 20), toxic multinodular goiter (n = 20), and Hashimoto thyroiditis (n = 20), and 20 healthy controls. HIF-1α levels were measured in blood samples and 8-OHdG levels were measured in urine - both via ELISA. HIF-1α and 8-OHdG levels were significantly higher in the patient groups than in the control group (p 0.05). There was no significant difference in 8-OHdG or HIF-1α levels between the patients with biopsy results that were benign, malignant, and non-diagnostic (p > 0.05). Serum HIF-1α and urine 8-OHdG levels were significantly higher in the patients with thyroid diseases; however, a relationship with cancer was not observed.

Serum butanol extractable iodine values for adolescents exposed in utero - Nagasaki

Serum BEI determinations were performed on 249 fifteen year old exposed and nonexposed apparently normal children all of whom were in utero at the time of the atomic bombing in Nagasaki, Japan. The girls were more mature in growth and development than the boys; the boys were probably near the peak stress of adolescent development. No statistically significant difference of BEI values was found between exposed and control groups. The trimester of gestation of the children at the time of exposure appeared to have no conclusive effect on the BEI value, but the number of subjects from each trimester was too small for satisfactory statistical analysis. Eleven females with goiter were analyzed separately. There was a slight preponderance of goiter in the exposed group, but the difference was not significant. The mean BEI value for the males was significantly lower than that for the females. The mean BEI values for Japanese adolescents are higher than for adolescents in the Middle Atlantic and New England states in the United States. 31 references, 2 tables.

Thyroid disorders are frequently encountered. The diagnosis is straightforward unless clinical or laboratory findings are inconclusive and/or perplexing. Hyperthyroidism due to a thyrotropin-secreting pituitary adenoma rarely occurs and symptoms due to thyroid hormone excess are subtle. The presentation of the disease becomes unusual when co-secretion of other hormones with thyrotropin or concomitant thyroid parenchymal pathology exist. We present the case of a 63-year-old female patient with...

To evaluate the effect of using tailored individual doses of radioiodine (¹³¹I) and fine tuning using low-dose antithyroid drug (ATD) in the treatment of Graves' disease, and an attempt to establish a therapeutic strategy that can keep both high rate of euthyroidism and low incidence of hypothyroidism. The dose of radioiodine was calculated using the calculated dose formula, and low-dose ATD was used as a way of fine tuning during follow-up. The intended dose of radioiodine was modified according to the patient's age at radioiodine therapy, thyroid size, and duration of hyperthyroidism before radioiodine therapy in the study group; it was set as 2.96 MBq/g of thyroid in the control group. Twenty patients with Graves' disease were nonrandomly assigned to the control group and 98 patients with Graves' disease to the study group. The outcomes, which included euthyroidism, hypothyroidism, and persistent hyperthyroidism, were determined according to the patients' states at the end of follow-up. In the study group, 74 patients (75.5%) achieved the euthyroid state, six patients (6.1%) became hypothyroid, and 18 patients (18.4%) remained hyperthyroid. The rate of euthyroidism was statistically different between the study group and the control group (75.5 vs. 50%, P=0.03). Of 98 patients with Graves' disease in the study group, 19 patients were additionally treated with ATD during follow-up, and 12 patients achieved euthyroidism. In different age groups or duration of hyperthyroidism groups, the rate of euthyroidism was not statistically different among subgroups of goiter grade 1, grade 2, and grade 3 (P>0.05). Similarly, in different age groups or duration of hyperthyroidism groups, the incidence of hypothyroidism was not statistically different among subgroups of goiter grade 1, grade 2, and grade 3 (P>0.05). However, binary logistic regression analysis showed that thyroid size was associated with overtreatment and undertreatment in our study. Individual doses of

Few data on iodine status in Somalia are available, but it is assumed that deficiency is a public health problem due to the limited access to iodized salt. We aimed to describe the iodine status of the population of Somalia and to investigate possible determinants of iodine status. A national 2-stage, stratified household cluster survey was conducted in 2009 in the Northwest, Northeast, and South Central Zones of Somalia. Urinary iodine concentration (UIC) was determined in samples from women (aged 15–45 y) and children (aged 6–11 y), and examination for visible goiter was performed in the Northwest and South Central strata. A 24-h household food-frequency questionnaire was conducted, and salt samples were tested for iodization. The median UICs for nonpregnant women and children were 329 and 416 μg/L, respectively, indicating excessive iodine intake (>300 μg/L). The prevalence of visible goiter was Somalia is among the highest in the world and excessive according to WHO criteria. Further work is required to investigate the geochemistry and safety of groundwater sources in Somalia and the impact on human nutrition and health. PMID:24500936

High titer of maternal thyroid-stimulating hormone receptor antibody (TRAb) in patients with Graves' disease could cause fetal hyperthyroidism during pregnancy. Clinical features of fetal hyperthyroidism include tachycardia, goiter, growth restriction, advanced bone maturation, cardiomegaly, and fetal death. The recognition and treatment of fetal hyperthyroidism are believed to be important to optimize growth and intellectual development in affected fetuses. We herein report a case of fetal treatment in two successive siblings showing in utero hyperthyroid status in a woman with a history of ablative treatment for Graves' disease. The fetuses were considered in hyperthyroid status based on high levels of maternal TRAb, a goiter, and persistent tachycardia. In particular, cardiac failure was observed in the second fetus. With intrauterine treatment using potassium iodine and propylthiouracil, fetal cardiac function improved. A high level of TRAb was detected in the both neonates. To the best of our knowledge, this is the first report on the changes of fetal cardiac function in response to fetal treatment in two siblings showing in utero hyperthyroid status. This case report illustrates the impact of prenatal medication via the maternal circulation for fetal hyperthyroidism and cardiac failure.

Capsules or solutions containing Na{sup 131}I are indicated for the therapy of some thyroid carcinomas such as functioning metastatic papillary or follicular carcinoma of the thyroid; and for the treatment of hyperthyroidism (diffuse toxic goiter and single or multiple toxic nodular goiter). The recommended dosage ranges of Na{sup 131}I capsules or solution for the therapy of the average patient (70 kg) are: (3.7-5.55) GBq for ablation of normal thyroid tissue; (3.7-7.4) GBq for subsequent treatments; a (148-370) MBq for hyperthyroidism. The purpose of this paper is to calculate effective dose as a result of iodine-131 capsules remaining in stomach before absorption starts. This result can determine the disadvantage of capsule versus solution containing sodium iodine-131 (Na{sup 131}I) in radionuclide therapy application from radiation protection point of view. The Monte Carlo code MCNP4b was used to model transport of gamma and beta particles emitted by radionuclide {sup 131}I treated as a point source at the bottom of stomach. Absorbed energy per unit transformation in stomach and surrounding organs has been calculated. (authors)

Treatment of hyperthyroidism is one of the major problems in thyroidology. The well known and widely exploited treatment modalities in patients with hyperthyroidism are antithyroid drugs, radioiodine treatment and thyroid surgery, the latter two being considered definitive. Radioiodine treatment is effective and well tolerated treating modality, which major disadvantage is the impossibility of exact calculation of the dose needed. Lots of dosage regimens are approved, including empirically chosen fixed dose regimen. The aim of the study is to define the overall success rate in patients with hyperthyroidism in subgroups Grave's disease and toxic nodular goiter treated with fixed dose 185MBq regimen. Of all treated patients a low fixed dose regimen was chosen in 43. All the patients were followed up clinically, with ultrasonography and hormone levels for a period of minimum 1 year. Part of the patients with persistent hyperthyroidism 6 months after the initial treatment receive a second dose of 185MBq 131-1. The overall success rate in the subgroup with Grave's disease was 87% by the time of the study, compared to a considerably lower success of 62% in patients with toxic nodular goiter. (authors)

The history of postpartum thyroid dysfunction (PPTD) dates back almost two millennia, when Soranus of Ephesus, who practiced obstetrics and neonatology, observed swelling in the necks (presumably goiters) of women after pregnancy. The next reference to PPTD appeared in artwork more than 1000 years later, with many portraits illustrating women with goiter while holding infants. In the early to mid-19th century, Caleb Hillier Parry and Armand Trousseau described postpartum hyperthyroidism, while in the late 1800s, Sir Horatio Bryan Donkin reported the first patient with postpartum hypothyroidism. The modern era of PPTD began with the description in the late 1940s by H.E.W. Roberton of women after delivery reporting hypothyroid symptoms and responding to thyroid extract. The immunologic influence on PPTD was recognized initially by Parker and Beierwaltes in the early 1960s, and the clinical variability and natural history were carefully documented by numerous investigators in the 1970s-1980s. The past two decades have seen further refinements in understanding the prevalence, etiology, and treatment of PPTD. Yet to be determined is the role of screening as a cost-effective measure.

Objective: To establish a fluorescent-enzyme immunoassay (FEIA) with recombinant human thyroid peroxidase (hTPO) as the antigen. Methods: Sera of 326 healthy people, 119 cases of Hashimoto's thyroiditis (HT), 116 cases of Graves disease (untreated), 28 cases of nodular goiter, 10 ca-ses of subacute thyroiditis and 6 cases of simple goiter were measured by the FEIA with recombinant hTPO as the antigen. Rrank sum test and χ 2 -test were used in inter-groups. Results: (1) Concentration above 4000 U/L was considered to be positive. (2) The intra-assay coefficient of variation (CV) and the inter-as-say CV were 4.59% ∼ 6.52% and 17.37% ∼ 17.45%. (3) The values measured by the FEIA were positively correlated with the values measured by hTPO antibody (hTPOAb) commercial kit (r=0.80, P 2 = 53.45, 39.30, 15.41 and 21.74, all P < 0.01). Conclusions: The method can be applied in the serum measurement of thyroid disease. HT presented the highest positive rate, therefore, the FEIA was an effective method in diagnosing HT. (authors)

This prospective study was designed to evaluate the potential contributions of high resolution ultrasonography (US) and Tc-99m scintigraphy in the routine diagnosis of thyroid disease. The diagnostic impacts of US and Tc-99m scintigraphy results in 177 patients visiting our thyroid clinic were assessed and scored according to the following criteria: when the information provided by either test supported, confirmed or changed the initial clinical diagnosis, they received scores of 2, 3 and 4 respectively, while score 1 was given when the test itself was useless for the differential diagnosis. US identified focal lesions that both palpation and scintigraphy had failed to detect in 14 (12.1%) of 116 patients with diffuse thyroid diseases, suggesting the necessity of Hashimoto's thyroiditis, adenoma, adenocarcinoma and adenomatous goiter, and vice versa in the diagnosis of hyperthyroid and euthyroid Graves's diseases. Thus, the advantages of US over scintigraphy for morphological evaluation were confirmed. US was particularly useful for the differential diagnosis of adenomatous goiter from Hashimoto's thyroiditis or a single nodular disease. In contrast, scintigraphy gave functional images, being especially helpful for the differential diagnosis of thyrotoxicosis. (author).

Magnetic resonance imaging was performed in 38 diffuse goiters, including 30 chronic thyroiditis and 8 Basedow disease. MR findings were analyzed as to degree of swelling, margin, internal structures including homogeneity and low intensity bands. With regard to signal intensity, thyroid-muscle-signal intensity ratios on T1 and T2-weighted images were measured in 19 normal thyroid glands, 30 chronic thyroiditis and 8 Basedow disease. Additionally thyroid-muscle-signal intensity ratios were compared between 19 hypothyroid glands and 11 euthyroid glands in chronic thyroiditis. Chronic thyroiditis tended to show lobulated margins, inhomogeneous intensity, and low intensity bands connecting with vessels or not. Basedow disease tended to display smooth margins, inhomogeneous intensity and low intensity bands connecting with vessels. Thyroid-muscle-signal intensity ratios of Basedow disease and chronic thyroiditis were significantly higher than those of normal thyroid gland at all sequences. In chronic thyroiditis thyroid-muscle-signal intensity ratios of euthyroid glands were significantly higher than those of hypothyroid glands. MR imaging could reflect pathologic features of diffuse goiters. Moreover, MR imaging is potentially contributory to speculate about thyroid function and degree of serious condition in diffuse thyroid disorders. (author)

Aim: There is high incidence of goiter and goiter associated thyroid problems including high uptake disorders in iodine deficient areas. Most of the patients referred for diagnosis and therapy belong to poor socio-economic status. It is important to develop a simple and cost effective technique, which can provide diagnosis with high sensitivity and specificity. The aim of this on-going study is to evaluate thyroid to parotid ratio (TPR) as a diagnostic tool for routine management of functional thyroid disorders. Method: A total of 850 non selected consecutive have been included in this study. Apart from thorough clinical examination and documentation of symptoms in a specially designed thyroid proforma, blood samples for T3, T4 and TSH estimations were drawn before injecting 37 - 74 MBq (1-2 mCi) 99mTc - Pertechnetate. After about 30 min thyroid scans were performed under a gamma camera (ORBITOR 7500, Siemens AG). From the anterior image, regions of interest were designated over the thyroid and parotid glands and the ratio of the activity were calculated. In 20 normal volunteers TPR was calculated in the same manner. Results: In normal volunteers TPR was found to be 1.725+- 0.395 (Mean +- 1 SD). And the upper limit of normal was kept as 2.5 (Mean +- 2 SD). In all euthyroid patients the TPR was less than 2.5. Hyperthyroid patients(Graves' disease + Hyperthyroid nodular goiters) showed high TPR (more than 2.5) in 92% of the patients. Compared to the diagnosis based on T3, T4 and TSH values TPR showed a sensitivity of 93.7% and specificity of 88.5%. In 51 proven cases of thyroiditis TPR could correctly differentiate thyroiditis from hyperthyroidism in 92%. Conclusion: TPR appears to be a simple diagnostic parameter with high sensitivity and specificity for the diagnosis of hyperthyroidism. It can effectively differentiate thyroiditis from hyperthyroidism. Since TPR results can be made available along with morphological information from thyroid scan it appears to be

742 cases of thyroid diseases treated at Radio-isotope Clinic, Seoul National University Hospital since October 1965 through July 1968 were analyzed. The patients were classified according to eye findings, as to Infiltrative, Non-infiltrative and No ophthalmopathy. Correlations between ophthalmo-logical findings and symptoms, BMR values and {sup 131}I uptake rate as well as response to medical treatment were carefully reviewed. Results obtained were as follows: 1) Among goitrous patients 44.5% with infiltrative ophthalmopathy, 24.1% with non-infiltrative ophthalmopathy totaling 68.6% of patients with one or more eye findings were found. Exophthalmos (44%) and visual disturbances (44%) comprised the highest incidence among eye signs. Most frequent eye symptoms were lid swelling (17.1%). 2) Female patients were predominant (91%). 3) Of cases with hyperthyroidism, after treatment with antithyroid drugs and radio-iodine therapy, general symptoms were improved in over 74%, whereas ophthalmopathy was not changed and in some cases the eye signs were aggravated. This tendency was more apparent in infiltrative ophthalmopathy. 4) Significant correlations between exophthalmos, BMR values and {sup 131}I uptake rate were found. Among the patients of same degree of exophthalmos, BMR values and {sup 131}I uptake rate showed the highest in non-infiltrative ophthalmos, BMR values and {sup 131}I uptake rate showed the highest in non-infiltrative ophthalmopathy, moderate in infiltrative ophthalmopathy and the lowest in no ophthalmopathy.

Grave's disease is an autoimmune disease of the thyroid gland characterized by hyperthyroidism, a homogenous goiter and occasionally an ophtalmopathy. It occurs in less than 1% of the population with a large predominance in women (10/1). Treatment is directed to inhibit thyroid hormone synthesis with carbimazole during 12-18 months. Recurrence rates after stopping treatment is about 50%; in these patients, radioactive iodine is the preferred treatment.

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

The patient's symptoms had started shortly after she experienced emotional stress. Diagnostic work-up disclosed an avid radioactive iodine uptake by the goiter. On ultrasound examination, the thyroid gland was enlarged with a diffusely hypoechogenic structure and intense vascularization. Thyroid scintigraphy with (131)I; ultrasonography of the thyroid gland; and measurements of serum free T(3), free T(4), TSH levels and thyroid autoantibodies, including autoantibodies against thyroglobulin (TgAb), thyroperoxidase (TPOAb) and TSH receptor (TRAb). Graves disease, with stress-related onset and subsequent stress-related exacerbations. The patient was treated with methimazole to normalize levels of thyroid hormone and thyroid autoantibodies, and with bromazepam to help her cope with stress. The daily dose of methimazole was kept low during pregnancy. Over the 4 year period when the patient was taking methimazole, exacerbations of hyperthyroidism occurred twice: during her first pregnancy and 9 months after her first delivery. On all three occasions, symptoms were preceded by stressful life events. Further exacerbations were avoided by starting bromazepam treatment soon after the patient experienced stressful events.

The occurrence of thyroid disorders is connected with iodine deficiency, defective synthesis or releasing of thyroid hormone and endemicity. Genetic factors are known as a single gene defects, interaction of multiple genes with environmental factors, as well as chromosomal aberrations. Diofnosis thyroid disorders is enforced by 13I uptake test, thyroid scanning with 131 I or 99m Tc and serum radioimmunoassays of T3, T4, free T4 and TSH. They were largely classified as hypothyroidism, hyperthyroidism, simple goiter and normal. The pedigree of 58 families was drawn by propositus, and then the correlation between thyroid disorders and TSH levels was analyzed. The results are as follows: 1) The offsprings and their mothers of 15 families were hypothyroidism, THS level was 5 folds for offsprings and 4 folds for mothers in comparison with control group. 2) 13 families were hyperthyroidism in siblings but their mothers were normal in thyroid function, TSH level of the siblings was lower than control group. 3) Though the offsprings and their mothers of 10 families were similar to TSH level of control group, they are all simple goiter, familial thyroid disorders, in other thyroid function test. The familial thyroid disorders suggested that these transmitted from mothers to offsprings with X-linked dominant or autosomal dominant inheritance.

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

To explore the status of iodine nutrition and iodine deficiency disorders in the pasturing areas and agricultural regions in Tibet. 30 families were selected respectively in pastoral Dangxiong county and agricultural Qushui county of Lasa. Drinking water and edible salt were collected for testing the iodine contents. In each type of the following populations including children aged 8 - 10, women of child-bearing age and male adults, 50 subjects were randomly sampled to examine their urinary iodine contents. Among them, 50 children and 50 women were randomly selected for goiter examination by palpation. Water iodine content was less than 2 µg/L, both in pasturing area and in agricultural areas. There was no iodized salt used in the families of pasturing areas, while 90% people consumed iodized salt in agricultural areas. The median of urinary iodine in pasturing area was 50.2 µg/L, significantly lower than that of agricultural area (193.2 µg/L). However, the goiter rate of children and women in pasturing area was significantly lower than that in agricultural area. Although iodine intake of populations in pasturing area of Tibet was severely deficient, there was no epidemic of Iodine Deficiency Disorders. This phenomenon noticed by the researchers deserved further investigation.

Full Text Available A large number of predisposing factors (obesity, nasal obstruction, adenoid hypertrophy, macroglossia, etc. are reported to be associated with obstructive sleep apnea syndrome (OUAS. In addition to these factors, the large goiter and hypothyroidism were reported to be associated with OSAS as well. However, this relationship could not yet be fully demonstrated. In our case related to plonjon goiter, we wanted to show the effect of hyroidectomy to OSAS and #8211;if there is- and the relationship between pressure and OSAS. Two years ago, a 72-year-old female with BMI: 26.8 kg/m2 patient was admitted to our clinic with complaints of respiratory standstill during sleep, snoring, morning headaches and drowsiness during daylight. In the chest X-ray, chest computed tomography and ultrasonography applied to the patient, it was detected that the trachea was deviated to the left due to euthyroid plonjon goiter and severe OSAS and polisomnografisi (PSG was diagnosed for the patient. The patients apnea-hypopnea index (AHI was measured 63.1/h. With the aim of treatment, in 7cm H2O pressure, nasal continuous positive airway pressure (nCPAP was applied to the patient and AHI decreased to the level of 11.4/h. Thyroidectomy was performed one month after the diagnosis. AHI was found 34.8 /h on the PSG applied for the purpose of 8 week-postoperative control. There were recovery on the levels of total sleep time, AHI, obstructive apnea index, hypopnea index, average desaturation index, stage 3 and REM as 16%, 44.8%, 84.7%, 19%, 38.3%, 52.4% and 28% respectively when compared the preoperative term with and postoperative term. It was demonstrated that there was no change of the in the degree of OSAS after thyroidectomy but only some partial improvement in the OSAS. The conclusion that there may be some improvements in nCPAP pressures after thyroidectomy and nCPAP treatment should not be stopped was reached. Also, it should be kept in mind that patients who apply to

Effectiveness of radioiodine for Graves' hyperthyroidism depends on retention time of 131 I in the thyroid, and may be effected by several factors, including previous treatment with antithyroid drugs,goiter volume, 24 h thyroidal radioactive iodine uptake and so on. A short course of therapy with low dose of lithium carbonate increased retention of 131 I in the thyroid and prolong the intrathyroidal effective half-life of 131 I before and after 131 I therapy in patients with Graves' disease, because of the actions that lithium blocks the release of organic iodine and thyroid hormone from the thyroid gland without affecting thyroidal radioactive iodine uptake. Therefore, using lithium as adjunct to radioiodine therapy increases the radiation dose delivered to the thyroid, to result in reduced the activity required and whole-body radiation dose in patients with very short effective half-life, and so improve the cure rate of hyperthyroidism. A short course of lithium carbonate therapy can be considered a useful adjunct to 131 I therapy for obtaining a more rapid control of thyrotoxicosis and avoiding its transient exacerbation because of methimazole withdrawal prior to 131 I administration or in patients who cannot tolerate or do not respond to antithyroid drugs, and for helping to prevent the radioiodine-associated increase in serum free thyroid hormone concentrations. In addition, lithium carbonate enhances the effectiveness of 131 I therapy, in terms of prompter control of hyperthyroidism in patients with small or large goiters. At the same time, lithium also may increases the rate of permanent control of hyperthyroidism in patients with large goiters. In summary, in the short-term lithium plays an important role as an adjunct to 131 I, since it helps to prevent the 131 I-associated increase in serum free thyroid hormone concentrations and allows a more prompt control of thyrotoxicosis. This is of particular importance in high risk patients, such as the elderly

To study the prevalence of primary thyroid disorders in patients who underwent endogenous hypercortisolism. Retrospective evaluation of 59 patients with Cushing's syndrome (CS) who had, at least, a record of thyroid palpation by expert endocrinologists and basal measurements of TSH by second generation assays. When available, tri-iodothyronine and thyroxine serum levels, TRH-TSH tests and anti-thyroid antibodies were also analyzed. There were two age- and gender-matched control groups. The 'goiter control group' comprised 118 healthy subjects who underwent thyroid palpation. The 'antibody control group' was composed of 40 individuals who attended the blood bank of our hospital. Antibodies against thyroperoxidase and measurements of TSH were analyzed in their blood samples. Available files of 83 CS patients admitted to our endocrine unit from 1985 to 1998 were examined. Fifty-nine patients (52 women and 7 men) with a mean age of 36.2 years (range 14-61 years) met the above requirements. Diagnosis of hypercortisolism had been established by a standard 1-mg overnight dexamethasone suppression test and urinary free cortisol (UFC). Etiological diagnosis involved dynamic testing, measurements of ACTH levels and imaging techniques. After treatment, all but one of the patients were cured or controlled of their hypercortisolism. This was established by the finding of subnormal serum cortisol concentrations and/or subnormal 24-h UFC levels. Primary thyroid disorders were defined by the presence of one or more of the following diagnostic criteria: (i) goiter, (ii) positive anti-thyroid antibodies and/or (iii) primary thyroid function abnormalities. Eighteen (30.5%) patients had goiter (diffuse in 78% and nodular in 22%), 14 (23.7%) had primary subclinical hypothyroidism and 5 (8.4%) had hyperthyroidism. In 41 patients evaluated for antithyroid antibodies, it was found that 23 (56.1%) had positive titers. In a group of patients in which thyroid autoantibodies were measured

Several recently published investigations showed a significant improvement in the iodine supply of the German population, but so far Germany is still considered an iodine deficient country. However most of the studies presented do not meet the epidemiological criteria established by WHO, UNICEF and ICCIDD and may therefore suffer from a selection bias with respect to goiter prevalence estimates. School children, owing to their easy recruitment, representativeness of different socio-economic classes and high vulnerability of Iodine deficiency disorders (IDD), are one of the best target groups for surveillance of IDD. In this field study a total of 591 children were investigated. The total sample included 268 females and 323 males aged 7-17 years. The following data were collected: thyroid size by ultrasound, urinary iodine concentration in a first-morning spot urine, weight, height, sex and age. The median urinary iodine concentration of the children was 183 microg/L. The proportion of samples with concentrations below 100 microg/L or below 50 microg/L was 15.4% and 4.3% respectively. Urine samples with high iodine concentrations were also found amounting to 17.3%. Almost all families (97%) declared to use iodized kitchen salt and 19.6% of all children are taking regularly iodine tablets. Application of the WHO/ICCIDD thyroid volume references to the German children resulted in a goiter prevalence of 0.2%, using either age/sex-specific or body surface area (BSA)/sex-specific cut-off values. Comparison with the P97 values of the original normative data of Gutekunst and Martin-Teichert however gives a goiter prevalence of 3% as expected. The thyroid volumes of the children in our study appear comparable with those reported recently for iodine sufficient children from Switzerland and for iodine replete Berlin children and for children with sufficient iodine supply in the region of Leipzig, so that Germany probably has no longer to be considered an iodine deficient

The present non randomized clinical trial was conducted in the Center for Nuclear Medicine and Ultrasound, Mymensingh, Bangladesh for duration of one year. Total 30 patients with hyperthyroidism diagnosed by clinical and biochemical profile were included in the study. All patients received radioiodine treatment and regular follow up at 1st month, 3rd month, 6th month & 9th month were done to evaluate clinical and biochemical status and complications. Data were analyzed by computer with SPSS programme using 't' test and chi-square test. In the present study, out of 30 respondents more than three fourth of the respondents (76.6%) were in the age group of 31-50 years followed by less than 30 years are group (16.7%) and rest of respondents were in the age group of more than 50 years (06.7%). Mean±SD and range of age of the respondents were 39.80±10.02 years and 17-65 years respectively. Among the 30 respondents 11(36.7%) were male and 19(63.3%) were female. Male to female ratio was 1:1.73. Out of 30 patients 26(86.7%) presented with goiter and among them 21(80.8%) has diffused goiter and five (19.2%) had nodular goiter. Baseline mean±SD, median, range of serum T₃ level were 5.24±3.62, 4.34, 1.48-14.65nmol/L respectively. Base line mean±SD, median range of serum T₄ level were 192.25±99.17, 201.77, 1.75-336.25nmol/L respectively. Baseline mean±SD, median range of serum TSH level were 6.33±23.93, 0.15-0.07, 130.46nmol/L respectively. In the present study serum T₃, T₄ level among the respondents sharply decrease from baseline to 2nd follow up then gradually decrease from 2nd to 4th follow up. Serum TSH level gradually increases from baseline to 3rd follow up and then gradually decreases from 3rd to 4th follow up. The result showed radioiodine is an effective option for the treatment of thyrotoxicosis.

Introduction: hyperthyroidism is a relatively common disorder caused by different etiologies, Graves' disease and toxic-nodular goiter(Plummer's disease) are among the most common causes. Treatment with radioiodine is considered to be the treatment of choices in many of the patients. Higher biological half-life of 13I in hyperthyroid patients as compared with patients with differentiated thyroid carcinoma who have undergone thyroidectomy, may lead to a higher frequency of complications with radioiodine at similar dosage. Therefore gonadal dysfunction in hyperthyroid patients treated with radioactive iodine is not likely. Materials and methods: hyperthyroid patients with the clinical diagnosis of Graves' disease , toxic multi nodular goiter and toxic adenoma were entered the study. Their age distribution was 16-40 years in women and 17-70 years in men (reproductive years). Patients were euthyroid at the time of radioiodine treatment. FSH, LH, testosterone and semen analysis in men; and FSH, LH, estrogen and progesterone in women were measured before and 3 months after radioiodine therapy. All patients with previous history of radioiodine treatment, those with known sexual hormone abnormalities, women with a history of tube ligation and men with a history of vasectomy, as well as those women who were receiving OCP contraception were excluded from the study. results: From 104 enrolled patients, 40(38.5%) were men and 64(61.5%) were women. The case of hyperthyroidism was Graves' disease in 66 cases(63.5%), toxic multi nodular goiter in 28 cases (26.9%), and toxic adenoma in 10 others (9.6%). Hormonal status was normal in all patients before therapy while this became abnormal in 20(19.2%) of patients after treatment. Semen analysis became abnormal in 8/20(40%) of the patients after treatment. Conclusion: among different variables which were analyzed during study, meaningful correlation was found in the following situations: FSH values in men and women were found to be

Thyroid nodules are a common disorder, with 4-7% of incidence in the Brazilian population. Although the fine needle aspiration (FNA) is an accurate method for thyroid tumors diagnosis, the discrimination between benign and malignant neoplasm is currently not possible in some cases with high incidence of false negative diagnosis, leading to a surgical intervention due to the risk of carcinomas. The aim of this study was to verify if the Fourier Transform infrared spectroscopy (FTIR) can contribute to the diagnosis of thyroid carcinomas and goiters, using samples of tissue and aspirates. Samples of FNA, homogenates and tissues of thyroid nodules with histopathological diagnosis were obtained and prepared for FTIR spectroscopy analysis. The FNA and homogenates samples were measured by {mu}-FTIR (between 950 . 1750 cm{sup -1}), at a nominal resolution of 4 cm{sup -1} and 120 scans). Tissue samples were analyzed directly by ATR-FTIR technique, at a resolution 2 cm{sup -1}, with 60 scans in the same region. All spectra were corrected by the baseline and normalized by amides area (1550-1640 cm{sup -1}) in order to minimize variations of sample homogeneity. Then, spectra were converted into second derivatives using the Savitzk-Golay algorithm with a 13 points window. The Ward's minimum variance algorithm and Euclidean distances among the points were used for cluster analysis. Some FNA samples showed complex spectral pattern. All samples showed some cell pellets and large amount of hormone, represented by the bands of 1545 and 1655 cm{sup -1}. Bands in 1409, 1412, 1414, 1578 and 1579 cm{sup -1} were also found, indicating possible presence of sugar, DNA, citric acid or metabolic products. In this study, it was obtained an excellent separation between goiter and malign lesion for the samples of tissues, with 100% of specificity in specific cluster and 67% sensibility and 50 of specificity. In homogenate and FNA samples this sensibility and specificity were lower

Both inadequate and high intakes of iodine are associated with thyroid disease and associated abnormalities. Consumption of foods deficient in iodine induces hypothyroidism. Conversely, excessive intake of the nutrient precipitates hyperthyroidism. Iodine deficiency causes impairment of thyroid hormonogenesis resulting in goiter (struma), cretinism which is associated with increased prenatal and infant mortality, deafness, motor disabilities and mental retardation due to damage during fetal and neonatal brain development. We have assessed the iodine status of school children from the locality of Port Sudan, Red Sea State of Eastern Sudan. The primary sources of iodine of the children are mainly iodized salt and rations supplied by local donors and various aid agencies operating in the Sudan. Male and female children (n=141), aged 6 to 12 years (median age 9.8 years), were selected for the survey using a multistage random sampling technique, between May 22 and August 25, 2006. All the children were assessed for urinary iodine and visible goiter. In addition, the iodine content of twenty salt samples was determined using the lodometric titration method and spot test kits. The components of other foods that are routinely consumed by the children and households were noted using a questionnaire form. Urinary iodine concentration exceeded 300 microg/l and 1000 microg/l in 65% and 9.9% of the children, respectively. The highest urinary iodine level was 1470 microg/l. The prevalence of visible goiter was 17%. All the salt samples collected from the schools had more than 150mg potassium iodate per kg of salt. The results of this pilot survey reveal that excessive intake of iodine in children exists in Port Sudan. Inappropriate and unregulated local fortification of salt and lack of monitoring of the imported and donated salt is the primary reason for the excessive intake. There is an urgent need for a regulatory mechanism during the process of iodine fortification and at

T 3 immunoassay kit was investigated basically and clinically. A good result was obtained at the prescribed incubation temperature and for 16 hours of incubation time. Moreover, it was thought to be possible that incubation time could be shortened to 1 - 4 hours at 37 0 C. Specificity of antibody was good. Recovery of added T 3 was 100+-5 (S.D.) % on an average and parallel of dilution curve of high T 3 serum was also good. Variation coefficient of accuracy of this kit was 1.5 - 2.1 % and that of reproducibility was 1.3 - 6.6 %. Mild hemolysis did not affect measurement value. Serum T 3 level in normals, untreated patients with Basedow's disease and patients with primary hypothyroidism was 142+-21 ng/100 ml, 452+-156 ng/100 ml and 67+-17 ng/100 ml, respectively. Serum T 3 level in patients with Hashimoto's disease was distributed to a wide extent, but that of patients with goiter and simple goiter ranged within normal range. On the other side, serum T 3 level of normal pregnant woman was high and that of patients with anorexia nervosa showed low level. From the above mentioned results, it was concluded that this kit was simple in method and good in sensitivity, specificity and reproducibility and it was also useful for clinical applications. (M.

Full Text Available Despite the ongoing programs aimed at the liquidation of iodine deficiency in the Republic of Uzbekistan, a high prevalence of iodine deficiency disorders (IDD is being observed. As a result of epidemiological studies in 1998 and 2004 it was found that the prevalence of endemic goiter among children in the country was 64.5 and 51.6%, respectively. Dynamics of iodine deficiency decrease was associated with active work on liquidation of IDD: provision of salt-mining and salt-processing plants with iodizing equipment and potassium iodate, conducting of large-scale community health measures among different social gropus, on public enterprises and in private sector, carrying out of regular monitoring of iodine content in salt and urine. In May 2007 there was passed the law of Republic of Uzbekistan «About prevention of iodine deficiency disorders». In this work there was carried out the analysis of IDD in Khoresm region according to WHO recommendations, by sentinel method. It was revealed that prevalence of endemic goiter has been reduced to 38.7 % in 2012 (positive dymanics. We obtained data on the normal content of iodine in salt and urine — 75 and 60.6 %, respectively. Thus, it is found that the prevalence of IDD in the Khorezm region in the dynamics is reduced, although iodine deficiency remains severe.

Calegaro, J.U.M.; Calegaro, N.Q.M.

During 3,5 years (July 74 - December 77) 130 cases of subacute thyroiditis were observed at Londrina county, North area of Parana State; this disease was considered a peculiar problem of local pathology on thyroid disorders. These cases had the following distribution: 89 in the initial stage, 36 in the transition, 2 in remission and another 3 considered as of delayed and ciclic character. Women predominated by a factor of 5,19; the peak age was 30-40 years and it had a seasonal preference for winter and spring. Factors that mislead the diagnosis are pre-existing goiter (12,3%) and infectious diseases of the upper respiratory tract (35,38%). The goiter was diffuse in 50% of the cases and nodular in 30%; the thyroid had a normal size in the others. Painless gland occurred in 5 cases. The laboratory examinations are so important for diagnosis as for disease staging and evolution. Thyrotoxicosis occurred in 31 cases of the initial stage. Hypothyroidism in the transition state was present in 8 cases: 1 clinical and 7 subclinical. Evidence, for permanent functional impairment was demonstrated for 2 patients. Corticotherapy was the effective treatment, without evidence of good response with analgesic-antiinflammatory association. Thyrotoxicosis of the initial stage showed satisfactory results to the propanalol (β adrenergic blockage). Surgery was restricted to patients with eventual residual nodule. (author) [pt

Autonomously functioning thyroid nodules (AFTNs) can present as hyperfunctioning adenomas or toxic multinodular goiters. In the last decade, a large number of activating mutations have been identified in the thyrotropin receptor (TSHR) gene in autonomously functioning thyroid nodules. Most have been situated close to, or within the sixth transmembrane segment and third intracellular loop of the TSHR where the receptor interacts with the Gs protein. In this study we describe two novel mutations in the sixth transmembrane segment of the TSHR causing hyperfunctioning thyroid nodules. Genomic DNAs were isolated from four hyperfunctioning thyroid nodules, normal tissues and peripheral leukocytes of two patients with toxic multinodular goiter. After amplifying the related regions, TSHR and G(s)alpha genes were analyzed by single-strand conformation polymorphism (SSCP) analysis. The precise localization of the mutations was identified by automatic DNA sequence analysis. Functional studies were done by site-directed mutagenesis and transfection of a mutant construct into COS-7 cells. We identified two novel TSHR mutations in two hyperfunctioning thyroid nodules: Phe631Val in the first patient and Iso630Met in the second patient. Both mutant receptors display an increase in constitutive stimulation of basal cyclic adenosine monophosphate (cAMP) levels compared to the wild-type receptor. This confirms that these mutant receptors cause hyperfunctioning thyroid nodules.

2012-01-01

Abstract Background While it is recognized that patients sometimes recover from autoimmune hypothyroidism, little is known about how rapidly this may occur. Case reports Two 13 year old girls had severe primary hypothyroidism (total T4 14.2 nmol/L with TSH 468 miU/L and total T4 7.7 nmol/L with TSH 183 miU/L) accompanied by goiter and positive thyroid peroxidase antibodies. There were delays in starting thyroid hormone replacement, and complete reversal of hypothyroidism was documented within...

In Gerel’s native village there is a hydrogen sulphate spring which is good for mosquito bites. But the spring is poisonous and many children in the village suffered from goiter. Gerel says melted butter was widely used in the treatment of many diseases. People smeared their hair with butter, massaged their ailing joints and drank butter with Kalmyk tea (which is believ...

Technetium 99m pertechnetate scans in congenital hypothyroidism

Goiters are rarely palpable in infants with congenital hypothyroidism except in the case of maternal ingestion of iodide. The presence or absence of glandular tissue is, however, important for genetic and prognostic counseling and for acceleration of diagnosis in other affected siblings. The detection of thyroid tissue by /sup 99m/Tc pertechnetate scans in a significant number of our patients heretofore considered athyreotic establishes that physical findings and traditional laboratory data are not adequate to determine whether or not thyroid tissue is present

The data obtained testify to an increase in the number of children and adolescents operated on for thyroid benign neoplasms after the Chernobyl accident.According to pathohistological diagnosis nodular and multinodular goiters were the most frequent.A tendency towards a decrease in the percentage of follicular adenomas and cystadenomas was observed in spite of an increase in the absolute number of cases.All these changes in structure of benign surgical thyroid pathology allow us to presuppose radiation effects and demand more careful epidemiological and radiological analysis

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

The most common reason of acquired hypothyroidism is autoimmune (Hashimoto) thyroiditis. Autoimmune thyroiditis can be atrophic or goitrogenic. Atrophic autoimmune thyroiditis (ATT) related acquired hypothyroidism causes interruption of growth, obesity, and bone age retardation in early ages while goitrogenic thyroiditis has a higher incidence rate and mostly presents with diffuse goiter. We discuss the effects of hypothyroidism on various systems through a case found to have pericardial effusion during the echocardiography performed after cardiac murmur was detected and later diagnosed with ATT related hypothyroidism.

/sup 131/I studies in pulmonary tuberculosis

Yedurappa, K G [K.M. Coll., Hubli (India)

The increased I/sup 131/ uptake in the untreated tuberculous patients is probably due to the complex changes in the entire body metabolic processes as a result of tuberculous infection but not due to thyroid function disorder. Prolonged administration of isoniazid and PAS may depress thyroid hormones production with or without signs of goiter or hypothyroidism when these drugs are commonly used in the treatment of tuberculosis. The blocking effect of INAH and PAS might be in the iodine binding capacity rather than iodide concentrating mechanism.

Full incorporation of Strattice™ Reconstructive Tissue Matrix in a reinforced hiatal hernia repair: a case report

2012-08-01

Full Text Available Abstract Introduction A non-cross-linked porcine acellular dermal matrix was used to reinforce an esophageal hiatal hernia repair. A second surgery was required 11 months later to repair a slipped Nissen; this allowed for examination of the hiatal hernia repair and showed the graft to be well vascularized and fully incorporated. Case presentation A 71-year-old Caucasian woman presented with substernal burning and significant dysphagia. An upper gastrointestinal series revealed a type III complex paraesophageal hiatal hernia. She underwent laparoscopic surgery to repair a hiatal hernia that was reinforced with a xenograft (Strattice™ Reconstructive Tissue Matrix, LifeCell, Branchburg, NJ, USA along with a Nissen fundoplication. A second surgery was required to repair a slipped Nissen; this allowed for examination of the hiatal repair and graft incorporation 11 months after the initial surgery. Conclusion In this case, a porcine acellular dermal matrix was an effective tool to reinforce the crural hiatal hernia repair. The placement of the mesh and method of fixation are believed to be crucial to the success of the graft. It was found to be well vascularized 11 months after the original placement with no signs of erosion, stricture, or infection. Further studies and long-term follow-up are required to support the findings of this case report.

Antithyroid antibodies in hyperthyroidism - personal experience

International Nuclear Information System (INIS)

Dedoussis, H.

2003-01-01

Thyroid diseases of autoimmune type may be expressed by symptoms and signs of either hyperthyroidism or euthyroidism or even hypothyroidism. Common factor in these diseases is the presence in the serum of these patients of antithyroid or anti-TSN autoantibodies in various percentages. Since there is not always a positive correlation between the levels of these antibodies and the severity of thyroid disease we have studied in cases of Graves disease (GD), Multinodular toxic goiter (MTG) and Toxic adenoma (TA), the anti-microsomal antibody (antithyroid peroxidase-ATPO-Ab), the antithyroglobulin antibody (Tg-Ab) and the anti-TSH receptor antibody (TSH-Ab) in 260 patients with the three above forms of hyperthyroidism. In Group A, GD, 23 men and 44 women, in Group B MTG, 24 men and 71 women in Group C TA, 8 men and 25 women and in Group C patients with clinical hyperthyroidism without detectable goiter, 19 men and 46 women. thyroid status was assessed clinically by the so called thyroid index of hyperthyroidism, modified by the authors and by the laboratory tests of free thyroxine (FT4), free triiodothyronine (FT3), TSH and the I-131 uptake by the thyroid gland. Results showed that TPO-Ab were in the 4 Groups:75%, 36%,6%, and 66%. The Tg-Ab were:48%, 25%, 0% and 28%. The TSH-Ab were: 49%, 27%, 12% and 23% respectively. Results show that: a) the percentage of TPO-Ab an GD is high and is related to the duration and or the size of the goiter, since in Group D there was a lower percentage of positive TPO-Ab. b) TSH-Ab and Tg-Ab are of minor importance in differentiating different types of hyperthyroidism and may as well be omitted. c) in patients with GD the high levels of TPO-Ab are not synchronous but are related to the severity and/or the relapse of the disease. d) Tg-Ab although not expected are sometimes increased in hypothyroidism as well as in normal people. e) in order to realize the importance of TSH-Ab we should be able to test the number and the sensitivity of

To evaluate the extent of differential item functioning (DIF) within the thyroid-specific quality of life patient-reported outcome measure, ThyPRO, according to sex, age, education and thyroid diagnosis. A total of 838 patients with benign thyroid diseases completed the ThyPRO questionnaire (84 five-point items, 13 scales). Uniform and nonuniform DIF were investigated using ordinal logistic regression, testing for both statistical significance and magnitude (∆R(2) > 0.02). Scale level was estimated by the sum score, after purification. Twenty instances of DIF in 17 of the 84 items were found. Eight according to diagnosis, where the goiter scale was the one most affected, possibly due to differing perceptions in patients with auto-immune thyroid diseases compared to patients with simple goiter. Eight DIFs according to age were found, of which 5 were in positively worded items, which younger patients were more likely to endorse; one according to gender: women were more likely to report crying, and three according to educational level. The vast majority of DIF had only minor influence on the scale scores (0.1-2.3 points on the 0-100 scales), but two DIF corresponded to a difference of 4.6 and 9.8, respectively. Ordinal logistic regression identified DIF in 17 of 84 items. The potential impact of this on the present scales was low, but items displaying DIF could be avoided when developing abbreviated scales, where the potential impact of DIF (due to fewer items) will be larger.

The present study deals with the change of the 99m Technetium-pertechnetate thyroid uptake under suppression (TcTU s ) in dependence on the urinary iodine excretion. The study collective comprises 510 patients with euthyroid goiter (N=91), with functional thyroid autonomy (N=361) and with Graves' disease (N=58), who were examined in the now thyroid ambulance between January 1995 and February 1997 and who presented with endogeneous or exogeneous TSH-supression. All patients received a quantitative thyroid scintigraphy with 99m Technetium-pertechnetate and a measurement of the urinary iodine excretion. The TcTU s from the whole collective shows an inverse correlation to the urinary iodine excretion for the range of 0 to 500 μg iodine/g creatinine. The TcTU s remains constant on a low basal level for iodine excretion values over 500 μg iodine/g creatinine. Significant differences occur in dependence on the underlying disease. TcTU s is constantly low in patients with euthyroid goiter, independent of the iodine excretion value. The TcTU s is significantly increased in patients with functional thyroid autonomy or Graves' disease when iodine excretion is below 100 or 50 μg iodine/g creatinine respectively, but shows only minor changes when iodine excretion rises up to 500 μg iodine/g creatinine. When iodine excretion exceeds 500 μg iodine/g creatinine, the TcTU s of patients with thyroid autonomy drops down to a low basal level. (orig.) [de

Full text: The coexistence of hyperthyroidism and thyroid cancer is a rare event. The aim of this study was to evaluate the relevance of the association of hyperthyroidism and thyroid cancer. Method: From 1st January 2006 to 31st December 2006, a total of 388 new hyperthyroid patients attended the Institute of Nuclear Medicine and Ultrasound for radioiodine therapy. Eighty-two of them were selected before radioiodine therapy, on the basis of findings on palpation and ultrasound (USG) examination, to undergo fine needle aspiration cytology (FNAC) for cytological diagnosis. USG examination was performed to localize and mark the position of nodule/nodules for FNAC and, in cases of nonpalpable nodules, USG guided FNAC was done. In the case of non-nodular patients, guided FNAC was done in sonographically suspicious areas. Results: FNAC report was positive for thyroid cancer in 4 patients. Histopathology examination revealed the presence of papillary carcinoma. Among the four positive cases, one had multi-nodular goitre, two had uni-nodular goiters and one had no nodule. Another patient had a negative FNAC report but due to a huge goiter, the patient underwent surgery and histopathology revealed the presence of papillary carcinoma. Conclusion: Although the occurrence of thyroid cancer in hyperthyroid patients is rare, the presence of a nodule should be carefully evaluated to exclude the presence of concurrent malignancy. FNAC (USG guided in case of non-palpable nodules) is found helpful before radioiodine therapy or surgery. (author)

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.

Fourteen hyperthyroid patients (11 men, three women), ages 28 to 66, were followed with serial measurements of serum thyroid hormone levels for 1 mo after therapy with I-131. Twelve patients had diffuse toxic goiters (25 to 70 g in size); two patients had multinodular glands (40 to 100 g). The patients were taking no antithyroid medications; ten patients were treated with propranolol. All patients received the equivalent of 5000 rad, except the two with multinodular glands, who received larger doses. There was no consistent pattern of serum T 4 and T 3 levels after the I-131 therapy. For the entire group, there was no significant increase of the mean serum hormone concentration. One group (three patients) had a mean T 4 increase of 28% and a T 3 increase of 91% above baseline at Days 10--11. Seven patients had minimal increases of hormone levels at Days 2--3, and a third group (four paients) had no increase of thyroid hormones after I-131 therapy. The patients with no rise in hormone concentrations had smaller goiters than the other groups. There was no correlation of the dose of radioactive iodine, or of the initial hormone concentration, with the rises or declines of T 4 and T 3 levels after I-131 therapy. Radioiodine therapy caused no significant increase of serum T 4 and T 3 concentrations in the majority of patients

Pendred syndrome (PS) is the second most common type of autosomal recessive syndromic hearing loss (HL). It is characterised by sensorineural HL and goiter with occasional hypothyroidism. These features are generally accompanied by malformations of the inner ear, as enlarged vestibular aqueduct (EVA). In about 50% of probands, mutations in the SLC26A4 gene are the cause of the disease. Here we report the case of a Portuguese female, aged 47, presenting with severe to profound HL and hypothyroidism. Her mother and sister, both deceased, had suffered from HL and goiter. By MRI and CT, an enlarged vestibular aqueduct and endolymphatic sac were observed. Molecular study of the patient included screening for GJB2 coding mutations and GJB6 common deletions followed by screening of all SLC26A4 exons, as well as intronic regions 8 and 14. Mutation c.918+2T>C was found for the first time in homozygosity in the intronic region 7 of the SLC26A4 gene. Whilst sequencing the control samples, a novel mutation c.821C>G was found in heterozygosity in the exon 7 of SLC26A4 gene and was predicted to be damaging. This study thus led to the finding of two novel SLC26A4 genotypes and provides new insight on the phenotypic features associated with PS. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

Early Hypoparathyroidism Reversibility with Treatment of Riedel's Thyroiditis.

Stan, Marius N; Haglind, Elizabeth G; Drake, Matthew T

2015-09-01

Riedel's thyroiditis (RT) is a rare, fibroinflammatory condition which induces gradual thyroid gland destruction and adjacent soft-tissue fibrous infiltration. About one- seventh of RT cases are associated with hypoparathyroidism, necessitating long-term therapy for symptomatic hypocalcemia. The reversibility of the parathyroid hormone deficit has not been fully described. A 40-year-old woman with no prior history of thyroid disease presented with a six month history of progressive thyroid enlargement complicated by worsening dysphagia and positional dyspnea. Her past medical history was remarkable only for retroperitoneal fibrosis. Physical examination revealed a large, hard, non-mobile goiter. Thyroid indices while maintained on levothyroxine were normal, but marked asymptomatic hypocalcemia with an inappropriately normal parathyroid hormone level was noted. Thyroid imaging and fine needle aspiration were consistent with RT. Isthmectomy and subsequent serial corticosteroid and tamoxifen treatment led to rapid symptom improvement. Serum calcium and parathyroid hormone levels returned to the reference range within three months. We describe a case of RT in which hypoparathyroidism resolved after treatment targeted the mechanical compression and the fibroinflammatory milieu of the patient's thyroidal disease. RT can be associated with hypoparathyroidism that is clinically silent at presentation. Mechanical decompression of the goiter and immunomodulatory therapy can reverse the fibrosclerotic process and lead to rapid recovery of parathyroid gland function, as in this patient. However, in most cases hypoparathyroidism is persistent and requires continued treatment to prevent symptomatic hypocalcemia.

Ectopic lymphoid follicle infiltration is a key event in Hashimoto thyroiditis (HT). Positive regulatory domain zinc finger protein 1 (PRDM1), which is induced by antigen stimulation, can regulate all lymphocyte lineages. Several groups independently demonstrated that human parvovirus B19 (PVB19) is closely associated with HT. Hence, we determined whether PRDM1 is expressed in HT thyroid tissue and whether there is any correlation between PRDM1 expression and PVB19 in the pathogenesis of HT. We detected PRDM1 expression in HT (n = 86), normal thyroid tissue (n = 30), and nontoxic nodular goiter (n = 20) samples using immunohistochemistry. We also detected PVB19 protein in HT samples in a double-blind manner and analyzed the correlation between the 2 proteins using immunofluorescence confocal detection and coimmunoprecipitation. Furthermore, we detected changes of the expression levels of PRDM1 and PVB19 in transfected primary thyroid follicular epithelial cells using real-time quantitative polymerase chain reaction. We found that PRDM1 protein is significantly highly expressed in the injured follicular epithelial cells in HT (83/86 cases) than in normal thyroid cells (0/30 cases) or in nontoxic nodular goiter cells (0/20 cases) (P thyroid epithelial cells also showed PRDM1 up-regulation after PVB19 NS1 transfection. Our findings suggest a previously unrecognized role of PRDM1 and PVB19 in the pathogenesis of HT. Copyright © 2015 Elsevier Inc. All rights reserved.
