    Full Text Available El hipertiroidismo se presenta con un cuadro clínico característico por la hiperproducción de hormonas tiroideas por el tiroides, y obedece a múltiples causas. Su forma clínica más frecuente es el bocio tóxico difuso o enfermedad de Graves Basedow. Es un síndrome caracterizado por manifestaciones de tirotoxicosis, bocio y manifestaciones extratiroideas, entre las que se encuentra la orbitopatía, que en ocasiones sigue un curso independiente de la enfermedad tiroidea. El interrogatorio, el examen físico y la determinación de hormonas tiroideas, son suficientes para confirmar el diagnóstico. Los pilares básicos del tratamiento, además de una adecuada orientación higiénico-dietética, son: el medicamentoso, el radioyodo y la cirugía, y su indicación debe ser individualizada para evitar la toma de conductas inadecuadas e innecesarias.Hyperthyroidism has a clinical picture characterized by overproduction of thyroid hormones by the thyroid gland and is derived from a number of causes. The most frequent clinical presentation is toxic diffuse goiter or Graves Basedow's disease. It is a syndrome with thyrotoxicosis, goiter and extrathyroid manifestations such as orbitopathy that occasionally develops regardless of the thyroid disease. Questioning, physical exam and estimation of thyroid hormones are enough to confirm the diagnosis. In addition to adequate hygienic-dietary orientation, the basis pillars of the treatment are drugs, radioiodine and surgery, but indication of treatment should be personalized to avoid inadequate and unnecessary behaviors.

  7. Atrial Fibrillation and Hyperthyroidism

    Full Text Available Atrial fibrillation occurs in 10 – 15% of patients with hyperthyroidism. Low serum thyrotropin concentration is an independent risk factor for atrial fibrillation. Thyroid hormone contributes to arrythmogenic activity by altering the electrophysiological characteristics of atrial myocytes by shortening the action potential duration, enhancing automaticity and triggered activity in the pulmonary vein cardio myocytes. Hyperthyroidism results in excess mortality from increased incidence of circulatory diseases and dysrhythmias. Incidence of cerebral embolism is more in hyperthyroid patients with atrial fibrillation, especially in the elderly and anti-coagulation is indicated in them. Treatment of hyperthyroidism results in conversion to sinus rhythm in up to two-third of patients. Beta-blockers reduce left ventricular hypertrophy and atrial and ventricular arrhythmias in patients with hyperthyroidism. Treatment of sub clinical hyperthyroidism is controversial. Optimizing dose of thyroxine treatment in those with replacement therapy and beta-blockers is useful in exogenous subclinical hyperthyroidism.

    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.

    Amiodarone is extensively used in cardiology practice because of its excellent antiarrhythmic properties. It produces alterations in thyroid functional because it contains 37% iodine and it is structurally similar to the thyroid hormones. Amiodarone inhibits 5'-deiodinase in the liver. The incidence of amiodarone-induced hyperthyroidism is between 6% and 12% of treated patients. The figures for pediatric patients are similar. Determination of tri-iodothyronine (T3), thyroxine (T4) and thyroid-stimulating hormone (TSH) plays an important role in the diagnosis and follow-up of thyroid alterations. Treatment options in amiodarone-induced hyperthyroidism in children include thionamide, potassium perchlorate, and prednisone. We present the case of hyperthyroidism secondary to amiodarone in a 10-year-old boy with Marfan's syndrome who was admitted several times for crises of paroxysmal supraventricular tachycardia and atrial fibrillation. After amiodarone treatment he presented a clinical and analytical picture of hyperthyroidism with very low TSH levels and increased free-T4 levels. Thyroid echography and scintigraphy were normal. Treatment with thiamazole did not alter the clinical picture, which returned to normal after prednisone administration. Currently, prednisone is being slowly withdrawn.Amiodarone. Hyperthyroidism.

    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

    Association of hyperthyroidism and pregnancy is not an unusual event, and has an impact on both the mother and fetus. After delivery, it may also affect the newborn and the nursing mother. Clinical management of this situation is quite different from that required by non-pregnant hyperthyroid women and poses significant diagnostic and therapeutic challenges. This review addresses aspects related to the unique characteristics of biochemical assessment of thyroid function in pregnancy, the potential causes of hyperthyroidism in pregnancy, and the clinical and therapeutic approach in each case. Special attention is paid to pregnancy complicated with Graves' disease and its different the maternal, fetal, neonatal, and postnatal consequences. Copyright © 2012 SEEN.

    Hyperthyroidism and sub-hyperthyroidism are common illnesses. Their diagnosis and their treatment are accessible to the general practitioner in the any great majority of the cases. A careful clinical examination already allows to direct the diagnosis. The development is simple and consists of a blood dosage, an ultrasound and sometimes a scintigraphy. Rare cases and severe forms are to be recognized and to refer to specialized centre. The treatment of first intention are betablockers. The comorbidities are cardiovascular (atrial fibrillation mostly) and skeletal (osteoporosis). Considering the increase of cardiovascular risks and the fracture risk in this pathology, the screening is especially indicated for women above 65 years. This screening is simple and little invasive, it consists of the annual dosage of the TSH.

    There are many clinical form of hyperthyroidism. It is necessary to determine the specific cause in order to direct the treatment strategy accordingly. The most common form is Graves' disease, an autoimmune disorder characterized by the presence of thyroid stimulating immunoglobulin that bind to and stimulate the thyrotropin receptor resulting in thyroid overactivity. Toxic nodular goitres, the next in prevalence, is more common in iodine deficient region and causes by autonomous hyperfunctioning thyroid nodules. The therapeutic approaches to treat hyperthyroidism are 1) antithyroid drugs to block hormones synthesis and release, 2) surgery and 3) radioiodine ablation of thyroid tissue. All therapeutic modalities are effective but the latter two methods are most probably the definitive means to achieve remission of the hyperthyroidism. Antithyroid drug therapy is the preferred treatment for all children with Graves' disease and patients with small goitres and short duration. However, a long term remission from antithyroid drug treatment is approximately 50%. Surgery is appropriate treatment for patient who has a very large goitre with symptoms of compression in the neck or patient with a cold nodule on thyroid scan. Currently radioiodine therapy is the most common therapy for Graves' disease. It is increasingly used as first-line therapy especially in elderly patients. It is the treatment of choice for patients with recurrent hyperthyroidism after antithyroid drug or surgical treatment. Radioiodine is also the preferred treatment for toxic nodular goitre. It is effective, safe and low cost. However it may aggravated Graves' ophthalmopathy. The only major disadvantage is high incidence of hypothyroidism. It is crucial that the patient be followed annually post treatment so that hypothyroidism can be detected early and proper treatment initiated. (author)

  17. Differential diagnosis of hyperthyroidism

    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. (orig.) [de

    Objective: The purpose of the study was (i) to diagnose the pregnant women suffering from hyperthyroidism by differentiating their symptoms from normal pregnancy and confirming this disease biochemically and (ii) to treat such patients medically to achieve euthyroid state of the mother while monitoring the developing fetus for better obstetrical outcome. Subjects and Methods: A total of 30 patients in reproductive age group, suffering from hyperthyroidism with pregnancy, were studied. Patients were recruited in the study in their first trimester having no associated medical problems. The patients were divided into two groups. Group I patients were diagnosed by hyperthyroidism for the first time during pregnancy by biochemical methods. These patients were treated medically methods. These patients were treated medically. After treatment effects on their previous obstetrical complications, general health and fetal well-being were monitored. The group II patients were already under medical treatment and served as control. Their thyroid status in all trimesters, types of medicine, dose adjustment and maternal and fetal well-being were compared with the patients of group I. The patients of both the groups were treated medically with beta blockers and anti-thyroids drugs mainly carbimazole. For fetal monitoring, ultrasonography (USG) and cardiotocography (CTG) were carried out. Results: The most common type of hyperthyroidism, in patients of both the groups was toxic nodular goiter that affected 70% of the patients. The most common previous obstetrical complication in patients of both the groups was abortion (85.7%), followed by premature labour (7%). Carbimazole was the drug of choice given to 70% and 60% patients of group I and group II respectively. Having achieved euthyroid state, dose reduction was possible in 65% patients of group I and 83% patients of group II. Conclusion: Euthyroid state in mothers, by the time of deliver, can be easily achieved with antithyroid

    Full Text Available Review on a problem of the development of atrial fibrillation in patients with thyrotoxicosis is presented. Thyrotoxicosis is one of the most frequent endocrine diseases, conceding only to a diabetes mellitus. The most frequent reasons of hyperthyroidism are Graves’ disease and functional thyroid autonomy. The authors give an analysis of data on the cardiac effects of thyrotoxicosis, features of heart remodeling under the influence of thyroid hyperfunction, prevalence of atrial fibrillation in thyrotoxicosis, depending on age, as well as the possibility of restoring sinus rhythm in the combination of these diseases. Particular attention is paid to the effect on the heart of subclinical thyrotoxicosis, which is defined as a dysfunction of the thyroid gland, characterized by low serum concentration of thyrotropin, normal values of free thyroxine and free triiodothyronine. Subclinical hyperthyroidism is also capable of causing heart remodeling and diastolic dysfunction.Prevalence of thyrotoxicosis in elderly people is higher in areas of iodine deficiency; it is relevant for our country due to the large territory of iodine deficiency. In elderly patients, the cardiac effects of thyrotoxicosis prevail in the clinical picture, that makes it difficult to diagnose endocrine disorders, and correction of thyrotoxicosis is critically important for the successful control of the heart rhythm. The article also discusses the problem of thyrotoxic cardiomyopathy, caused by the toxic effect of excess thyroid hormones: features of this heart disorder, factors affecting its formation, clinical significance and contribution to the development of rhythm disturbances. The greatest significance is the development of atrial fibrillation as a result of thyrotox-icosis in older patients who already have various cardiovascular diseases.Atrial fibrillation is the most frequent heart rhythm disorder in thyrotoxicosis.

    A ten year study (1988-98) was done at the Veterans Memorial Medical Center on radioiodine (RAI) therapy for hyperthyroidism. A total of 162 patients received 131-I after careful selection hence was included in this study. A predominantly female population was seen (81%) compared to only (19%) males. The most frequent age group were in the third and fourth decades of life. Those included had clinical manifestations of thyrotoxicosis aside from the abnormal thyroid function tests and elevated RAI uptake. Almost all were given antithyroid drugs and beta-blockers prior to RAI ablation. Doses ranged from 7 to 12 mCi depending on gland size and degree of toxicity. Success rate of treatment was 92% which meant that the symptoms were abated and there was shrinkage of the thyroid gland after a single dose of iodine. The most common short term complications were sialitis and local neck tenderness while hypothyroidism was the commonest long term complication. (author)

    Full text: Objective: To assess the efficacy of radioiodine therapy in teenage patients with hyperthyroidism. Method: The medical records of 28 patients (age range 16 -18 years) were purposely selected from a pool of 3637 hyperthyroid patients treated with radioiodine during the period January 1982 to December 2006. Data for analysis included the age, sex, clinical symptoms, type of hyperthyroidism, antithyroid medications received, doses of radioiodine therapy given and the outcome of the therapy after one and five years. Results: The mean age of the patients treated for hyperthyroidism was 17.60 ± 0.73 years and 82 % were females. The most common type of hyperthyroidism was Graves' disease (75%). All patients were pre-treated with antithyroid drugs for variable duration periods (6 months to 2 years). The mean administered dose of radioiodine was 10.69 ± 2.77 mCi. The dose of I-131 was calculated on the basis of gland size and morphology (assessment by palpation and scintigraphy) and percentage of radioactive iodine uptake. Effective control of hyperthyroidism after radioiodine treatment occurred in 60.72% patients with a single dose, 35.71% required a second dose and 3.57% required more than two doses. Frequency of early hypothyroidism within one year was 38.09 % in Graves' disease and 33.33% in toxic multinodular goiter. Most patients (66.66%) in the toxic nodule group remained euthyroid up to one year after I-131 therapy. Overall incidence rates of hypothyroidism after 1 year and 5 years of radioiodine therapy were 32.14% and 75%, respectively. Conclusion: Hyperthyroidism in the teen group of patients was effectively controlled with radioiodine. There were no early side effects. The only long-term effect was hypothyroidism. Appearance of early/late hypothyroidism showed a direct relationship with the type of hyperthyroidism and the dose of radioiodine administered. In general, patients with Graves' disease showed a greater tendency in the evolution of early

    A clinical analysis was made on 161 cases of hyperthyroidism seen at the Radioisotope Laboratory of Kyungpook National University Hospital. This series consisted of 144 cases of diffuse goiter and 17 cases of nodular goiter. 1) Hyperthyroidism was most prevalent in the 4th decade and male to female ratio was 1 : 4.6. 2) Cardinal symptoms in the order of frequency were weakness, easy fatigability, palpitation, weight loss, nervousness, perspiration, heat intolerance, increased appetite, insomnia and dysmenorrhoea. 3) Major physical findings in the order of frequency were goiter, fine tremor, tachycardia, wide pulse pressure, emaciation, warm moist skin, exophthalmos, systolic hypertension and atrial fibrillation. 4) The complications were ophthalmopathy (34.2%), thyrotoxic heart disease (5.6%), thyroid crisis (1 case), pretibial myxedema (1 case) and thyrotoxic myopathy (1 case). 5) Mean values of the six hour and twenty-four hour 131 I uptakes by the thyroid glands were 67.5% and 71.6%, respectively, in diffuse goiter and 64.5% and 65.0%, respectively, in nodular goiter. 6) Mean values of twenty-four PB 131 I conversion ratio were 76.3% in diffuse goiter and 70.2% in nodular goiter and those of the basal metabolic rate was +51% in the former and +41% in the latter. Mean serum cholesterol level was 152 mg% in diffuse goiter and that in nodular goiter was 175 mg%. 7) Among the 134 cases treated with 131 I, 66 cases (49.3%) were successfully controlled with single dose and in the majority of the cases the initial therapeutic dose required was 4.1-4.0 mC in diffuse goiter and 5.1-6.0 mC in nodular goiter. 8) With 131 I treatment the symptoms improved in the following order: heat intolerance, emaciation, nervousness, insomnia, easy fatigability, weakness, fine tremor, goiter, perspiration, exertional dyspnea and palpitation. And in a few cases improvement of even exophthalmos was seen. 9) Following 131 I treatment myxedema occurred in 4 cases (3%) and reoccurrence in 9

    The etiology of hyperthyroidism is still largely unknown and therefore no causal therapy of this condition is possible. Antithyroid drug treatment is usually carried out with thiocarbamides. When an euthyroid state is achieved synthetic thyroid hormones are added. Pregnancy and iodine contamination (after exposure to contrast medium) require individual treatment. In this paper the advantages, indications and contraindications are discussed as well as supportive drug therapy necessary in specific cases. Radioiodine therapy is reserved for patients over 35 years of age; the individual dose is calculated according to the size of the thyroid gland and the iodine uptake. Disadvantageous is the late onset of therapeutic efficiency, the small effect on the size of goitre and the exposure to radiation. A patient should be operated upon in an euthyroid state, i.e. after preoperative drug therapy. Operations are normally performed on individuals with a coexistent goitre or where antithyroid drugs or radioiodine therapy are contraindicated. Paresis of the recurrent laryngeal nerve and hypoparathyroidism are rare complications. 3 to 4 g of thyroid tissues should remain. Of great importance in all cases are precise diagnostics both before and after commencing treatment and adequate follow up.

    Iodine induced hyperthyroidism is a thyrotoxic condition caused by exposure to excessive iodine. Historically this type of hyperthyroidism has been described in areas of iodine deficiency. With advances in medicine, iodine induced hyperthyroidism has been observed following the use of drugs containing iodine—for example, amiodarone, and contrast agents used in radiological imaging. In elderly patients it is frequently difficult to diagnose and control contrast related hyperthyroidism, as most...

    To report several cases of hyperthyroidism in patients presenting with the unusual symptom of sleepwalking and to discuss the possible pathophysiologic basis for this novel association. After encountering and reporting the first case of new-onset somnambulism in a patient presenting with thyrotoxicosis at our institution, we routinely inquired about the sleep history of patients with thyrotoxicosis, questioning both the patients and family members when applicable. Those patients who actually had sleepwalking episodes coinciding with the onset of thyrotoxicosis underwent close follow-up, and the relationship between the sleepwalking and the results of thyroid function tests was analyzed. In addition, we reviewed the literature on psychiatric disorders and sleep problems, and the pathophysiologic rationale for a cause-and-effect relationship is discussed. We collected 8 cases of patients with new-onset sleepwalking episodes that coincided with the start of thyrotoxicosis. The disappearance of the sleepwalking with successful achievement of euthyroidism supports a cause-and-effect relationship. This hypothesis is further supported by the absence of a family history, the adult onset, and the relapse of sleepwalking in 2 of the patients when their thyrotoxicosis became poorly controlled as a result of noncompliance with medications and its subsequent disappearance with reachievement of euthyroidism. Of note, such a presentation was seen only in patients with thyrotoxicosis caused by diffuse toxic goiter or Graves' disease and never in patients with other causes of thyrotoxicosis. New-onset sleepwalking could be caused by thyrotoxicosis or, more specifically, by thyrotoxicosis resulting from diffuse toxic goiter. The mechanism is hypothesized to be related to the combination of prolongation of non-rapid eye movement sleep and the associated fatigue. Specific inquiry about this unusual presentation of thyrotoxicosis is encouraged, and more studies are needed to confirm

    In recent years increasing interest is shown in the use of 125 I for the therapy of hyperthyroidism, instead of the traditional 131 I, based on the postulate that there is a relative sparing of the reproductive integrity of the thyroid follicular cell and a consequent possibility of smaller incidence of hypothyroidism after therapy. Dosimetric and radiobiological bases of this postulate are first described in this paper and then a brief review of the results of the pilot clinical trials conducted at different centers using 125 I for the management of hyperthyroidism is given.

    Objective: To evaluate the method and result of thyroid artery embolization as a new therapy for hyperthyroidism. Methods: Twenty-two patients with hyperthyroidism underwent selective thyroid artery embolization. Totally 52 thyroid arteries were embolized with microspheres. The indications to this therapy were following: hyperthyroid patients having indications to surgical and 131 I therapy, clinically being difficult to complete the preparation for subtotal thyroidectomy and having high risk for surgical process because of their huge thyroid gland. Results: Serum level of thyroid hormones dropped significantly [median T3 from 8.8 nmol/L (4.3-43.0 nmol/L) to 4.0 nmol/L (1.1-9.2 nmol/L), median T4 from 206.4 nmol/L (77.4-748.2 nmol/L) to 144.5 nmol/L (25.8-279.9 nmol/L), P 131 I treatment of hyperthyroidism. A long term follow-up study is still needed

    Objective: To study the therapeutic effect and find new ways on treatment of Grave's hyperthyroidism in youngsters. Methods: 260 Grave's hyperthyroidism patients (age under 21 years) treated with 131 I were followed up 1-16 years later. Results: 118 of all patients were cured and 55 cases improved, failed treatment 2 cases, subclinical hypothyroidism 9 cases, clinical hypothyroidism 6 cases. 35 cases were treated with 131 I two or three times. All the patients with subclinical hypothyroidism and clinical hypothyroidism caused by 131 I were cured with medicine. 131 I treatment had no effect on growth and mentality and didn't cause leukemia nor thyroid cancer. Conclusions: The therapy of youngsters with Grave's hyperthyroidism with 131 I has the same effectiveness as adult. To the youngster Grave's patients who failed medical treatment, therapy with 131 I is safe and effective. It leads to temporary hypothyroidism which can be cured with medicine, no delayed hypothyroidism has been found

    Amiodarone can induce severe hyperthyroidism that justifies its withdrawal and initiation of antithyroid drugs. Impossibility to stop amiodarone, failure to control hyperthyroidism and unfavourable evolution can lead to thyroidectomy. Cardiac manifestations, persistence of hyperthyroidism and interactions between amiodarone and anaesthetic or haemodynamic drugs may contraindicate anaesthesia. We report nine consecutive cases of amiodarone-associated hyperthyroidism that prompted us to perform thyroidectomy under general anaesthesia. The features and anaesthetic data of patients were noted. The antithyroid medical treatment failed in all patients. After thyroidectomy, evolution was favourable in all nine cases, without any intra or postoperative complication, in spite of the extent of hyperthyroidism and the severity of the associated cardiac problems. Despite potential high risks, thyroidectomy for amiodarone-induced hyperthyroidism does not seem to increase morbidity or mortality and allows a quick return to euthyroidism and reintroduction of amiodarone.

  13. Thyroid Hemiagenesis Associated with Hyperthyroidism

    Full Text Available Thyroid hemiagenesis (TH, very rare congenital anomaly, is generally asymptomatic. We report two cases of TH with hyperthyroidism. Case One. The patient presented with signs and symptoms of thyrotoxicosis. Physical examination revealed asymmetric nodular goitre at right lobe. Biochemical analysis revealed the diagnosis of hyperthyroidism. Ultrasound showed multinodular hypertrophy in the right lobe and absence of the left lobe. Nuclear scan, confirming absence of the left lobe, showed hot nodules in the right one. The diagnosis was toxic multinodular goitre. Case Two. The thyroid was not palpable in this patient presented with signs and symptoms of thyrotoxicosis. Biochemical analysis revealed the diagnosis of autoimmune thyrotoxicosis. Ultrasound showed mild diffuse hyperplasia of the right lobe and agenesis of the left lobe. Nuclear scan, confirming absence of the left lobe, showed increasing diffuse uptake of radiotracer in the right one. The diagnosis was Graves’ disease in this patient. After antithyroid medication, the patients were surgically treated with total excision of the thyroid tissue. TH is sometimes associated with disorders of the thyroid. Hyperthyroidism makes TH cases symptomatic. During evaluation of patients, ultrasound and nuclear scan usually report agenesis of one lobe and establish the diagnosis of TH. The surgical treatment is total removal of hyperactive tissue and total excision of the remaining lobe.

    Background Graves’ disease and Hashimoto’s thyroiditis are the two autoimmune spectrum of thyroid disease. Cases of conversion from hyperthyroidism to hypothyroidism have been reported but conversion from hypothyroidism to hyperthyroidism is very rare. Although such cases have been reported rarely in the past we are now seeing such conversions from hypothyroidism to hyperthyroidism more frequently in clinical practice. Case presentation We are reporting three cases of middle aged Asian female...

    We report a case of toxic multinodular goiter with severe symptomatic hyperthyroidism in a female diagnosed 5 months after successful renal transplantation. To our knowledge, this is the first well-documented case of hyperthyroidism in a renal transplant recipient that responded well to methimazole. Special attention should be made to the use of methimazole and the possible interaction with immunosuppressive drugs.

    Acquired immune deficiency syndrome (AIDS) is an immune deficiency disease. The etiology of hyperthyroidism, which can also be immune-related, is usually divided into six classical categories, including hypophyseal, hypothalamic, thyroid, neoplastic, autoimmune and inflammatory hyperthyroidism. Hyperthyroidism is a rare complication of highly active antimicrobial therapy (HAART) for human immunodeficiency virus (HIV). Hyperthyroidism caused directly by AIDS has not been previously reported. A 29-year-old man who complained of dyspnea and asthenia for 1 month, recurrent fever for more than 20 days, and breathlessness for 1 week was admitted to our hospital. The thyroid function test showed that the level of free thyroxine (FT4) was higher than normal and that the level of thyroid-stimulating hormone (TSH) was below normal. He was diagnosed with hyperthyroidism. Additional investigations revealed a low serum albumin level and chest infection, along with diffuse lung fibrosis. Within 1 month, he experienced significant weight loss, no hand tremors, intolerance of heat, and perspiration proneness. We recommended an HIV examination; subsequently, AIDS was diagnosed based on the laboratory parameters. This is the first reported case of hyperthyroidism caused by AIDS. AIDS may cause hyperthyroidism by immunization regulation with complex, atypical, and easily ignored symptoms. Although hyperthyroidism is rare in patients with AIDS, clinicians should be aware of this potential interaction and should carefully monitor thyroid function in HIV-positive patients.

    A 56-year-old woman with autoimmune hyperthyroidism (Basedow) whose blood coagulation had at first been normal developed prolonged partial thromboplastin time (PTT) of 48 s and a fall in prothrombin time (Quick value) to 52%. At the same time, total activity of factor VIII was reduced to 18% and factor IX to 16%. These values not having changed after the addition of normal plasma, it is assumed that an acquired inhibitor of plasmatic coagulation was responsible. Such inhibitors were first described in lupus erythematodes and therefore called lupus anticoagulant, but later also demonstrated in other autoimmune diseases.

    Full Text Available The coexistence of hyperthyroidism with gestational trophoblastic disease is a known albeit rare clinical condition. We herein report the successful anesthetic management of such a case in our institute. There are only few case reports in literature of this association. Often, the diagnosis of hyperthyroid state is retrospective one, as it can be missed in the emergency scenario of patient requiring molar evacuation. This case report highlights the perioperative management and optimization of hyperthyroid state prior to surgical evacuation of the invasive hydatidiform mole.

    Tremelimumab and ipilimumab are monoclonal antibodies directed against the extracellular domain of cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) and have been used as immunotherapies against immune checkpoints that suppress T-cell activation. Anti-CTLA-4 antibody-based therapies have been shown to be effective in treating various cancers including metastatic melanoma. However, a few immune-related adverse events including hypophysitis and thyroid disorder have been reported, mostly developed within the first year of receiving treatment. We report a case of tremelimumab-induced Graves hyperthyroidism in a 55-year-old man who was diagnosed with metastatic melanoma after 8 years of tremelimumab therapy. He had no personal or family history of thyroid or autoimmune diseases. His biochemical profile was in keeping with Graves disease, with raised serum free thyroid hormones, suppressed thyroid-stimulating hormone concentration, and raised thyrotropin receptor antibody level. He was treated with carbimazole as part of the block and replace therapy, without complications. Tremelimumab therapy was temporarily discontinued and recommenced when he was rendered biochemically euthyroid. There has been no further relapse of Graves hyperthyroidism since the discontinuation of block and replace therapy. The mechanistic profile of anti-CTLA-4-induced thyroid dysfunction and the long-term endocrine safety of this therapeutic approach remain unclear. It is important to monitor thyroid functions in patients receiving anti-CTLA-4 therapies, as their effects on endocrine systems could be more latent or prolonged than the data from current clinical trials suggest. Antithyroid drug therapy was safe and effective alongside anti-CTLA-4 therapy without compromising antitumour treatment efficacy.

    Between 1971 and 1977, 102 hyperthyroidism patients were treated with 131 I. The average age of the patients was 64 years. In 78 patients, hyperthyroidism was due to decompensated autonomous adenoma, 24 patients presented with diffuse hyperthyroidism. The patients were observed for 14 to 24 months. Until early 1976, diagnosis and therapy success assessment were based on thyroid scintiscanning, radioiodine two-phase tests, PBI 131 , T 4 tests, and T 3 tests. Since 1976, the radioiodine two-phase test has been replaced by the TRH test, the TRH-RIA, and the T 4 -RIA. The patients were given 3 to 25 mCi 131 I. In 88 cases, euthyroidism was reached after a single therapy; in 8 cases, after two therapies; in 1 case, after three therapies; in 4 cases, after 4 therapies; in 1 case, after 5 therapies. Euthyroidism was thus reached in 96% of all cases after 131 I therapy of hyperthyroidism. (orig./MG) [de

    1998-07-01

    Full Text Available Hyperthyroidism is often accompanied by diverse types of neuropychiatric complications. To demonstrate these complications we studied 500 hyperthyroid patients, who developed neuropsychiatric complications of hyperthyroidism for which other causes of these neuropsychiatric findings were carefully excluded. The patients were 15 to 65 years old (female to male ratio was 5:1, most of the cases were in third and fourth decades of life. Nervousness, tense dysphoria, insomnia and anxiousness were among the most common psychiatric complications, and tremor, hyperreflexia, thyrotoxic myopathy, thyrotoxic periodic paralysis were the most common neurologic complications. Therefore any physician, wether he or she is a general practitioner or a specialist must be aware of these diverse complications, because these neuropsychiatric complications can lead to the diagnosis of hyperthyroidism and treatment of these potentially serious complications.

    We present the case of a person with baseline Bipolar Affective Disorder, who starts receiving medical treatment for subclinical Hypothyroidism, during this time the patient develops Hyperthyroidism. During the course of the latter, the patient started to exhibit depressed mood symptoms and worsening of her baseline disorder. Typically there are depressive symptoms in hypothyroidism and manic symptoms in hyperthyroidism, there have been a few cases of depressive symptoms (depressed mood, asthenia and apathy) reported in patients with hyperthyroidism. Up till now it's a fact that Hyperthyroidism constitutes itself as a risk factor for developing or precipitating depressive states, thus increasing hospital readmissions, and another important fact is that of manifesting or worsening affective symptoms due to the influence of thyroid hormones. We also present the well-known relationship between thyroid malfunction and affective disorders. Copyright © 2013 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

The physiological changes in the maternal immune system during a pregnancy may influence the development of this and other autoimmune diseases. Furthermore, pregnancy-associated physiological changes influence the synthesis and metabolism of thyroid hormones and challenge the interpretation of thyroid function tests in pregnancy. Thyroid hormones are crucial regulators of early development and play an important role in the maintenance of a normal pregnancy and in the development of the fetus, particularly the fetal brain. Untreated or inadequately treated hyperthyroidism is associated with pregnancy complications and may even program the fetus to long-term development of disease. Thus, hyperthyroidism in pregnant women should be carefully managed and controlled, and proper management involves different medical specialties. The treatment of choice in pregnancy is antithyroid drugs (ATDs. These drugs are effective in the control of maternal hyperthyroidism, but they all cross the placenta, and so need careful management and control during the second half of pregnancy considering the risk of fetal hyper- or hypothyroidism. An important aspect in the early pregnancy is that the predominant side effect to the use of ATDs in weeks 6–10 of pregnancy is birth defects that may develop after exposure to available types of ATDs and may be severe. This review focuses on four current perspectives in the management of overt hyperthyroidism in pregnancy, including the etiology and incidence of the disease, how the diagnosis is made, the

    Objective: To evaluate the method and efficacy of thyroid artery embolization as a new therapy for hyperthyroidism. Methods: Thirteen patients with hyperthyroidism underwent selective thyroid artery embolization. Totally 25 thyroid arteries were embolized with microspheres. The indications for this therapy were as followings: 1) To give hyperthyroid patients having an alternative for surgical and 131 I treatment, and 2) To provide a new method for those clinically being difficult to get control with medicine. Results: Serum level of thyroid hormones dropped significantly[T3 from 2.84-9.0 ng/ml to 0.8-2.2 ng/ml, T4 from 162.9-277.2 ng/ml to 50-126 ng/ml] and symptoms of hyperthyroidism were under control in 12 patients within 1 month after the embolization. One patient remained no change 1 month later and refused to be embolized again. The symptoms of twelve patients were effectively controlled through low dose antithyroid medication for more than 6 months follow up with no serious complications. Conclusion: Thyroid artery embolization with microspheres is an effective alternative for surgical and 131 I treatment of hyperthyroidism. (authors)

    To study the outcome of Radioactive Iodine (RAI) in treatment of hyperthyroidism. It is a retrospective study of all patients of hyperthyroidism treated by Radioactive Iodine (RAI) seen in endocrinology clinic at King Abdulaziz University Hospital and Dr. Soliman Fageeh Hospital in Jeddah, Saudia Arabia. Two hundred and sixteen (216) patients were treated by RAI. They proved to have hyperthyroidism by thyroid function test (TSH, FT4 and T3) and isotopes scanning of the thyroid gland. All received 10 mci of RAI and were then followed up after one month and every two months thereafter for at least one year. The efficacy of the therapy was assessed by the improvement of the clinical features and by the thyroid function tests. A total of 216 patients were seen, the mean age was 36.5+- 10.64 years. One hundred fifty three were female and sixty three were male. Graves disease was the underlying cause in 163 patients [65.55%], toxic multi nodular goiter in 37 patients [25.1%] and toxic adenoma in 16 patients [9.3%]. The symptoms improved after one month only in 11 patients but others required antithyroid treatment for two months. Only 17 patients remained hyperthyroid after six months of treatment. Radioactive iodine is very effective in treatment of hyperthyroidism with minor side effects such as weight gain, fatigability and hypothyroidism. (author)

    Hyperthyroidism is reportedly uncommon in the indigenous populations of Africa. The presenting symptoms volunteered, the symptoms elicited by direct questioning, and the results of physical examination were therefore prospectively compared in 60 Black and 56 White patients with thyrotoxicosis attending a single thyroid clinic. Fewer Blacks than Whites volunteered information about weight loss, while more Blacks complained only of the presence of a goitre. A 'chance' diagnosis of hyperthyroidism was made more frequently in Blacks. Symptomatology elicited by direct questioning and findings on physical examination were generally similar in each group, except that Blacks presented more frequently with complicated disease (cardiac failure and overt myopathy) and infiltrative ophthalmopathy. The frequency with which hyperthyroidism presents 'atypically' in Black compared with White patients may reflect educational, socio-economic and cultural differences in the Black and White populations, and may partly explain the infrequency with which this disease is diagnosed in Blacks

    1984-01-01

    Hyperthyroidism (HT) affects glucose metabolism in various ways. The role of insulin, glucagon and growth-hormone (GH) was determined. After glucose loading the insulin response is weaker in HT than in euthyroid subjects. Enhanced degradation of insulin has been reported. It is suggested that in HT the serum insulin concentration declines at a slightly accelerated rate. In HT the deranged carbohydrate metabolism might be a consequence of altered tissue sensitivity to insulin. To elucidate this problem insulin receptors on erythrocytes obtained from hyperthyroid women were investigated. The maximal specific binding of 125 I-insulin to RBC of hyperthyroid patients was decreased and the analysis refers to a decreased receptor concentration in RBC. The nature of glucagon secretion and its influence on glucose metabolism in HT was investigated. The basal plasma glucagon is elevated in hyperthyroid patients. The suppression of glucagon secretion induced by an oral glucose loading was of significantly lesser degree in hyperthyroid patients than in controls. Applying the erythrocyte receptor assay a decreased specific binding of 125 I-glucagon to RBC of hyperthyroid patients has been found and data indicate a significantly less glucagon receptor concentration in thyrotoxicosis. Physiological elevations of serum GH levels led to a significant impairment of glucose metabolism. Beside the GH-RH and somatostatin, the dopaminergic neurotransmitter system participates in the regulation of GH secretion too. It has been demonstrated that after administration of the dopamine agonist l-dopa the GH response was weaker in HT than in controls. This indicates that in thyrotoxicosis the GH secretion can not be stimulated in such a degree as in euthyroidism. (author)

    Hypokalemic periodic paralysis (HPP) is a rare disorder characterised by acute, potentially fatal atacks of muscle weakness or paralysis. Massive shift of potassium into cells is caused by elevated levels of insulin and catecholamines in the blood. Hypophosphatemia and hypomagnesemia may be also present. Acidobasic status usually is not impaired. HPP occurs as familiar (caused by ion channels inherited defects) or acquired (in patients with hyperthyroidism). On the basis of two clinical cases we present a review of hypokalemic periodic paralysis in hyperthyroid patients. We discuss patogenesis, clinical and laboratory findings as well as the principles of prevention and treatment of this rare disorder.

    Amiodarone is a highly effective antiarrhythmic agent used in life-threatening ventricular and supraventricular arrhythmias. Its long-term use may however lead to several adverse effects, including corneal deposits, liver and thyroid gland dysfunction, lung lesions, bone marrow injury, skin lesions, or neurological abnormalities. The article presents the case of a 56-year-old man with a history of a stroke, who after a few days of amiodarone therapy for an episode of atrial fibrillation was diagnosed with amiodarone-induced hyperthyroidism and interstitial pulmonary lesions. Clinical and laboratory symptoms of hyperthyroidism and radiographic signs of pulmonary involvement did not occur until several weeks after discontinuation of amiodarone therapy. Differential diagnosis of causes of hyperthyroidism and diseases causing nodular pulmonary lesions did not demonstrate any other pathologies. Empirical antibiotic therapy and administration of thiamazole and high doses of propranolol failed to improve the patient's clinical status. It was not until thiamazole was given in combination with glucocorticosteroids, when a slow relief of hyperthyroidism symptoms and resolution of radiographic pulmonary signs were observed. Based on the presented case, the risk of appearance of 2 serious concomitant adverse effects was demonstrated, even following a short-term amiodarone therapy. This paper also contains an overview of adverse effects which may be encountered during or after therapy with this effective antiarrhythmic agent. It was emphasized how important it is to select patients appropriately, and to monitor potential adverse effects during amiodarone therapy.

    Takotsubo cardiomyopathy (TC) is an atypical, severe but reversible form of acute heart insufficiency. It typically presents with left ventricular failure, transient apical and mid-segments hypokinesis, absence of significant coronary stenosis and new electrographic abnormalities and/or elevation in serum cardiac enzymes. Although TC ('broken heart syndrome') has classically been associated with emotional trauma, evidence suggests that other precipitants might exist, including iatrogenic and thyroid-mediated forms. Thyroid disease is a relatively common comorbidity in TC patients. We report a case of TC in a postmenopausal female with no history of emotional trauma or other potential precipitant factors who was diagnosed with amiodarone-induced hyperthyroidism during her hospital stay. Though some case reports of thyroid-related TC exist, we are not aware of any other reported case of TC precipitated by amiodarone-induced hyperthyroidism. TC is a relatively new, rare, transient, severe, but reversible cardiovascular condition that is characterized by an acute left ventricular cardiac failure, which can clinically, analytically and electrocardiographically mimic an acute myocardial infarction.Many precipitant factors have been described in TC, being the most classical and emotional trauma. However, thyroid dysfunction is also a significant condition frequently found in patients with TC.A hypercatecholaminergic state leading to cardiomyocyte damage has been established as the main fact of TC physiopathology. Hyperthyroidism induces an upregulation of β-adrenergic receptors.Both hyperthyroidism and hypothyroidism have been related with TC development. Most reported cases of TC involving thyroid dysfunction correspond to hyperthyroidism due to Graves-Basedow disease, but there are also descriptions with severe hypothyroidism, radioiodine treatment or thyroid surgery.Amiodarone is a class III antiarrhythmic agent widely used, and it is a well-known cause of thyroid

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

    Strategic planning of treatment of hyperthyroid disease must correspond to the pathophysiological mechanism of elevation of thyroid hormone serum concentration, i.e. excess stimulation, autonomous thyroid function, destruction induced hyperthyoroxinemia. In cases of excess stimulation one should go to extremes to save the essentially 'normal' thyroid gland and life-long antithyroid drug treatment confronts with total ablation of the thyroid gland in non remitting disease. Size and quantity of regions of autonomously functioning follicles/cells will be the determinant of therapeutic strategy in cases of autonomous thyroid function. Selective surgery confronts with radioiodine treatment aiming at 'restitutio ad integrum'. In destruction induced hyperthyroxinemia antiintlammatory and symptomatic measures may help to bridge the time to the return of normal hormone concentrations. Based on these considerations a detailed therapeutic strategy for hyperthyroid disease can be designed. (author)

    Full Text Available Takotsubo cardiomyopathy (TC is an atypical, severe but reversible form of acute heart insufficiency. It typically presents with left ventricular failure, transient apical and mid-segments hypokinesis, absence of significant coronary stenosis and new electrographic abnormalities and/or elevation in serum cardiac enzymes. Although TC (‘broken heart syndrome’ has classically been associated with emotional trauma, evidence suggests that other precipitants might exist, including iatrogenic and thyroid-mediated forms. Thyroid disease is a relatively common comorbidity in TC patients. We report a case of TC in a postmenopausal female with no history of emotional trauma or other potential precipitant factors who was diagnosed with amiodarone-induced hyperthyroidism during her hospital stay. Though some case reports of thyroidrelated TC exist, we are not aware of any other reported case of TC precipitated by amiodarone-induced hyperthyroidism.

    Eleven cats with hyperthyroidism were treated with radioactive iodine ( 131 I). Previous unsuccessful treatments for hyperthyroidism included hemithyroidectomy (2 cats) and an antithyroid drug (7 cats). Two cats had no prior treatment. Thyroid scans, using technetium 99m, showed enlargement and increased radionuclide accumulation in 1 thyroid lobe in 5 cats and in both lobes in 6 cats. Serum thyroxine concentrations were high and ranged from 4.7 to 18 micrograms/dl. Radioactive iodine tracer studies were used to determine peak radioactive iodine uptake (RAIU) and effective and biological half-lives. Activity of 131 I administered was calculated from peak RAIU, effective half-life, and estimated thyroid gland weight. Activity of 131 I administered ranged from 1.0 to 5.9 mCi. The treatment goal was to deliver 20,000 rad to hyperactive thyroid tissue. However, retrospective calculations based on peak RAIU and effective half-life obtained during the treatment period showed that radiation doses actually ranged from 7,100 to 64,900 rad. Complete ablation of the hyperfunctioning thyroid tissue and a return to euthyroidism were seen in 7 cats. Partial responses were seen in 2 cats, and 2 cats became hypothyroid. It was concluded that 131 I ablation of thyroid tumors was a reasonable alternative in the treatment of hyperthyroidism in cats. The optimal method of dosimetry remains to be determined

    To evaluate the radiologic findings and clinical feasibility of thymic enlargement in patients with hyperthyroidism. Seven patients with hyperthyroidism and anterior mediastinal bulging revealed by chest radiography were evaluated. The CT findings were analyzed with regard to the shape of the anterior mediastinal mass, surrounding infiltration, and enlargement of mediastinal lymph nodes. Whether or not tumor markers (alpha-fetoprotein, beta-human chorionic gonadotrophin, and chorionic embryonic antigen) showed increased levels was determined, and the size and thickness of the anterior mediastinal mass were measured and compared with previously described age-matched thymus data. In addition, changes in the thyroid gland were evaluated. In all seven patients, anterior mediastinal masses were bi-lobed, with no surrounding infiltration or enlarged mediastinal lymph node, and tumor marker levels showed no increase. The masses were therefore considered to be thymus. In six patients, the size of the thymus exceeded two upper standard deviations of mean value and in one patient, it was smaller than this. In three patients, PCNB (percutaneous needle biopsy) revealed normal thymic tissue and in two, follow-up chest PA demonstrated no interval change. CT showed that in three patients, the thyroid glands were diffusely enlarged. In patients with hyperthyroidism, an anterior mediastinal mass seen on chest radiographs was due to thymic enlargement. The recognition of CT findings of thymic enlargement in such patients may avoid unnecessary biopsy. (author)

    Forty one patients of hyperthyroidism were treated with Na 131 I. Men and women are in the ratio 1:3.1. The ages of patients are between twenties and sixties and the forties are the highest in number. The observation period of clinical courses is between 1 and 8 years. The number of patients observed over 5 years are 51% of them and over 2 years are 83%. The treatment frequency is as follows: On 37 cases each one was treated once with Na 131 I. 2 cases twice, 1 case at 4 times in 3 years and 1 case at 5 times in 6 years. The treatment doses are between 4,000-6,000 rad (40-60 Gray). In the cases treated with the irradiation dose of 6,000 rad, we often saw hypothyroidism. In cases aiming 4,000-5,000 rad, there is a tendency of leaving hyperthyroidism unrecovered. In conclusion, the patients should be treated giving 4,000-5,000 rad or with Na 131 I doses of 3-6mCi. If the effects of the treatment are insufficient, the patients should be further treated with anti-thyroid drug or treated again with Na 131 I. As the result, there are at present 25 cases (61.0%) in normal status of the thyroid gland, 12 cases (29.2%) in hyperthyroidism and 4 cases (9.8%) in hypothyroidism totaling 41 cases in all.

    The potential severity of amiodarone-induced hyperthyroidism, particularly in severe cardiopathy cases, necessitates a regular clinic and biologic thyroid control. The break in amiodarone and a medical treatment (synthetic antithyroid drugs, steroids, perchlorate of potassium) can be ineffective. The authors report the case of a patient with an right ventricle arythmogenic dysplasia, without thyroid history, who came back 3 years after the introducing of amiodarone with major hyperthyroidism. After failure of medical treatment, a total thyroidectomy permitted to quickly stop hyperthyroidism and to early reintroduce amiodarone. Surgery seems to be the radical treatment when hyperthyroidism doesn't respond to the medical treatment and when the cardiopathy requires amiodarone.

    Evidence indicates that cardiac hypothyroidism may contribute to heart failure progression. It is also known that heart failure is associated with an increased risk of atrial fibrillation (AF). Although it is established that hyperthyroidism increases AF incidence, the effect of hypothyroidism on AF is unclear. This study investigated the effects of different thyroid hormone levels, ranging from hypothyroidism to hyperthyroidism on AF inducibility in thyroidectomized rats. Thyroidectomized rats with serum-confirmed hypothyroidism 1 month after surgery were randomized into hypothyroid (N=9), euthyroid (N=9), and hyperthyroid (N=9) groups. Rats received placebo, 3.3-mg l-thyroxine (T4), or 20-mg T4 pellets (60-day release form) for 2 months, respectively. At the end of treatment, hypothyroid, euthyroid, and hyperthyroid status was confirmed. Hypothyroid animals showed cardiac atrophy and reduced cardiac systolic and diastolic functions, whereas hyperthyroid rats exhibited cardiac hypertrophy and increased cardiac function. Hypothyroidism and hyperthyroidism produced opposite electrophysiological changes in heart rates and atrial effective refractory period, but both significantly increased AF susceptibility. AF incidence was 78% in hypothyroid, 67% in hyperthyroid, and the duration of induced AF was also longer, compared with 11% in the euthyroid group (all PHypothyroidism increased atrial interstitial fibrosis, but connexin 43 was not affected. Both hypothyroidism and hyperthyroidism lead to increased AF vulnerability in a rat thyroidectomy model. Our results stress that normal thyroid hormone levels are required to maintain normal cardiac electrophysiology and to prevent cardiac arrhythmias and AF.

    A 47 Ca calcitonin study is described which is used in combination with a conventional balance study in 5 patients with hyperthyroidism both before and after therapy and in 1 control subject. The experimentally obtained data were analyzed according to Wendeberg and Dymling. The magnitude of the 47 Ca loss through perspiration could not be determined. This fact can affect the rate of accretion but not the other parameters of calcium kinetics. A markedly flow of tracer into bone (inflow, internal disappearance, accretion, rate of accretion) and of calcium out of bone (resorption, outflow) was observed

We present a report of a 15-year-old girl who was admitted to the psychiatry inpatient unit with symptoms of suicidal behavior, irritability, and impulsivity. One year previously, she had become more short-tempered, and had started to cut her wrists impulsively. Laboratory tests revealed subclinical hyperthyroidism. She was treated with anxiolytic and antithyroid drugs, and her suicidal ideation and irritability resolved. This case demonstrates that subclinical hyperthyroidism can be associated with suicidal behavior as well as overt hyperthyroidism. Early intervention is required to prevent suicidal behavior in patients with subclinical hyperthyroidism.Keywords: suicidal behavior, subclinical hyperthyroidism, anxiolytics

  8. The role of thyroid scanning in hyperthyroidism

    Radionuclide thyroid imaging was performed in 872 consecutive patients with hyperthyroidism. Of these, 84% were found to have diffuse toxic hyperplasia (Graves' disease), while 12% had autonomously functioning nodules (Plummer's disease), 3% had Graves' disease developing in a multinodular gland, and in the remaining 1%, either a clear diagnosis could not be established or the hyperthyroidism was due to thyroiditis or the Jod-Basedow phenomenon. It was found that a thyroid scan seldom provides additional diagnostic information in patients with Graves' disease when a diffuse goitre is present. However, if patients are to be treated with radioiodine ( 131 I), thyroid imaging with tracer quantitation can replace a 24-h 131 I uptake measurement, this having the advantages that the patients are required to attend only once, and that the gland size can be measured. In addition, visual confirmation of tracer uptake by the thyroid is obtained and patients with thyroiditis will not receive inappropriate therapy. When single or multiple thyroid nodules are palpated, a thyroid scan is crucial in establishing an accurate diagnosis, as it is not otherwise possible to differentiate between Plummer's disease and Graves' disease developing in a multinodular gland. Indeed, in 20 of our 63 patients (32%) with single autonomously functioning nodules, the initial clinical assessment had been incorrect. (orig.)

    Full Text Available In 1891, Von Recklinghausen first established the association between the development of osteoporosis in the presence of overt hyperthyroidism. Subsequent reports have demonstrated that BMD loss is common in frank hyperthyroidism, and, to a lesser extent, in subclinical presentations. With the introduction of antithyroid medication in the 1940s to control biochemical hyperthyroidism, the accompanying bone disease became less clinically apparent as hyperthyroidism was more successfully treated medically. Consequently, the impact of the above normal thyroid hormones in the pathogenesis of osteoporosis may be presently underrecognized due to the widespread effective treatments. This review aims to present the current knowledge of the consequences of hyperthyroidism on bone metabolism. The vast number of recent papers touching on this topic highlights the recognized impact of this common medical condition on bone health. Our focus in this review was to search for answers to the following questions. What is the mechanisms of action of thyroid hormones on bone metabolism? What are the clinical consequences of hyperthyroidism on BMD and fracture risk? What differences are there between men and women with thyroid disease and how does menopause change the clinical outcomes? Lastly, we report how different treatments for hyperthyroidism benefit thyroid hormone-induced osteoporosis.

    To attain a simple and reliable method of evaluating the thyroid function the reliability of the clinical manifestation and the conventional thyroid function tests in diagnosing the hyperthyroidism was studied. The subjects included 184 patients with hyperthyroidism and 66 cases with euthyroidism, who were treated at the Thyroid Clinic, Seoul National University Hospital, from July 1971 through August 1972. The observed results were as follows: l. In the cases of hyperthyroidism, 19% of the patients were male and 81% female; in the cases of euthyroidism, 7. 6% of the patients were male and 92. 4% female. The majority of the patients were in 2nd to 4th decades of their lives. 2. There were objective signs clearly manifested in hyperthyroidism which were rare or absent in the euthyroid state. These clinical signs included wide pulse pressure, tachycardia, systolic murmur, exophthalmos, tremor, and warm skin. In the hyperthyroid state 91. 3% of the cases manifested two or more of the above signs, whereas in the euthyroid state no patients manifested any two of the above signs. 3. The most frequent complaints of the patients with thyroid disease were palpitation, weight low, increased appetite, heat intolerance, perspiration, hunger feeling; nervousness, exertional dyapnea, etc. There was no clear difference in the incidence of the symptoms between hyperthyroidism and euthyroidism. 4. In the diagnosis of hyperthyroidism, the reliability of thyroid function tests was as follows: T 7 was 92. 4% reliable, 125 IT 3 resin uptake rate 91. 6% reliable, 131 I thyroid uptake rate in 24 hrs. 89. 4% reliable, serum T 4 level 85. 9% reliable and BMR 75. 5% reliable. Therefore the careful observation of the clinical manifestation of the disease is a simple and reliable way of making a correct diagnosis of either hyperthyroidism or euthymidism. 5. In hyperthyroidism there shows no correlationship between the results of the thyroid function test and clinical signs but a high BMR was

    Background Transient non-immune hyperthyroidism in early pregnancy is hyperthyroidism diagnosed for the first time in early pregnancy, without evidence of thyroid autoimmunity or clinical findings of Grave's disease and resolved spontaneously as the pregnancy progressed. Hyperemesis gravidarum (HG) is the commonest cause with 66%-73% of women with severe HG were found to have elevated thyroid function. Materials and methods We conducted a cross sectional study to determine the prevalence of transient hyperthyroidism in patients with hyperemesis gravidarum and its relation to the severity of nausea and vomiting. Severity of nausea and vomiting in pregnancy was assessed using the modified pregnancy-unique quantification of emesis (PUQE) scoring system. Each patient had urine and blood investigations which also included a full blood count and thyroid and renal function tests. Patients with abnormal thyroid function were retested at 20 weeks of gestation. The patients' demographic data, electrolyte levels, thyroid function and their respective PUQE score were analyzed. Results The prevalence of transient hyperthyroidism in women with hyperemesis gravidarum was 4.8%. Although there was a significant association between the severity of the PUQE score and hypokalemia (p = 0.001), there was no significant association with transient hyperthyroidism in early pregnancy (p = 0.072). Free T4 and TSH values of all women with transient hyperthyroidism were normalized by 20 weeks of gestation. Conclusion Transient hyperthyroidism in pregnancy is not significantly associated with the severity of the PUQE score. Women with transient hyperthyroidism in pregnancy are normally clinically euthyroid, hence a routine thyroid function test is unnecessary unless they exhibit clinical signs or symptoms of hyperthyroidism.

    Full Text Available Hyperthyroidism is one of the most common causes of cardiac failure. Blood volume expands greatly during pregnancy, especially after the last part of the second trimester. Such expansion exacerbates the symptoms of heart failure and accelerates the development of pulmonary edema when abnormal thyroid function is not well controlled. Two cases of pregnancy complicated with congestive heart failure and pulmonary edema due to hyperthyroidism are reported here. Both patients did not receive treatment for hyperthyroidism during pregnancy, and both sought clinical help during the third trimester. The clinical problems were resolved by medical management before delivery.

    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.)

    Full Text Available BACKGROUND: Although the etiology of bladder pain syndrome/interstitial cystitis (BPS/IC is still unclear, a common theme with BPS/IC patients is comorbid disorders which are related to the autonomic nervous system that connects the nervous system to end-organs. Nevertheless, no study to date has reported the association between hyperthyroidism and BPS/IC. In this study, we examined the association of IC/BPS with having previously been diagnosed with hyperthyroidism in Taiwan. DESIGN: Data in this study were retrieved from the Longitudinal Health Insurance Database. Our study consisted of 736 female cases with BPS/IC and 2208 randomly selected female controls. We performed a conditional logistic regression to calculate the odds ratio (OR for having previously been diagnosed with hyperthyroidism between cases and controls. RESULTS: Of the 2944 sampled subjects, there was a significant difference in the prevalence of prior hyperthyroidism between cases and controls (3.3% vs. 1.5%, p<0.001. The conditional logistic regression analysis revealed that compared to controls, the OR for prior hyperthyroidism among cases was 2.16 (95% confidence interval (CI: 1.27∼3.66. Furthermore, the OR for prior hyperthyroidism among cases was 2.01 (95% CI: 1.15∼3.53 compared to controls after adjusting for diabetes, coronary heart disease, obesity, hyperlipidemia, chronic pelvic pain, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, depression, panic disorder, migraines, sicca syndrome, allergies, endometriosis, and asthma. CONCLUSIONS: Our study results indicated an association between hyperthyroidism and BPS/IC. We suggest that clinicians treating female subjects with hyperthyroidism be alert to urinary complaints in this population.

    Full Text Available State of subclinical hypothyroidism can be considered as the optimal model for assessing the significance of thyroid stimulating hormone (TSH for bone tissue in clinical practice. Objective: to make a comparative analysis of the impact of subclinical hyperthyroidism of various origins on the performance of bone mineral density (BMD and bone metabolism parameters. Materials and methods. The study in an outpatient setting included 112 women with a diagnosis of subclinical hyperthyroidism and duration of menopause for at least 5 years. Among the examinees, endogenous subclinical hyperthyroidism has been detected in 78 women (group I, exogenous subclinical hyperthyroidism on the background of suppressive levothyroxine therapy (group II — in 34. The control group (group III included 20 women without thyroid dysfunction. Results. The study first conducted a comparative analysis of bone metabolism, BMD indicators, as well as parameters of phosphorus and calcium, blood lipids in women with subclinical hyperthyroidism of various origins. A positive correlation between markers of bone metabolism and free triiodothyronine (fT3 as hormones necessary for the development of the skeleton and to maintain its homeostasis indicates a physiological effect of parathyroid hormone and fT3 on bone tissue. It is shown that the bone metabolism and BMD depend not only on the content of TSH, but also on the causes of subclinical hyperthyroidism.Conclusions. In postmenopausal women with endogenous subclinical hyperthyroidism, there is a significant decline in BMD indices, more pronounced in the bones with the cortical structure. A negative correlation between markers of bone metabolism and TSH has been observed among all patients included in the study.

    Full Text Available El hipertiroidismo subclínico se define por la presencia de niveles disminuidos o no detectables de tirotropina, asociados a concentración de tetrayodotironina y triyodotironina libres dentro de parámetros normales. Su prevalencia en la población varía entre un 0,5 y un 16 % aproximadamente, y es el tratamiento con levotiroxina sódica la causa más frecuente. No siempre resulta tan asintomático, y las afectaciones principales ocurren sobre el sistema cardiovascular y óseo. Esta condición médica puede ser reversible espontáneamente. Por lo controversial del tema, el presente trabajo trata los aspectos clínicos más relevantes y la conducta a seguir.Subclinical hyperthyroidism is defined by presence of decreased o non-detected levels of thyrotropin, associated with free concentrations of tetraiodothyronine and triiodothyromime within normal parameters. Its prevalence in population differs between 0,5 % and 16 % approximately, and the sodium Levothyroxine treatment is the more frequent cause. Not always it is so asymptomatic, and main affections occur on cardiovascular and osseous system. This medical condition may be spontaneously reversible. Due to controversial of this topic, present paper approaching the more significant clinical features and the strategy to go on.

    Full Text Available Abstract Background: Hyperthyroidism is currently recognized to affect the cardiovascular system, leading to a series of molecular and functional changes. However, little is known about the functional influence of hyperthyroidism in the regulation of cytoplasmic calcium and on the sodium/calcium exchanger (NCX in the cardiac muscle. Objectives: To evaluate the functional changes in papillary muscles isolated from animals with induced hyperthyroidism. Methods: We divided 36 Wistar rats into a group of controls and another of animals with hyperthyroidism induced by intraperitoneal T3 injection. We measured in the animals' papillary muscles the maximum contraction force, speed of contraction (+df/dt and relaxation (-df/dt, contraction and relaxation time, contraction force at different concentrations of extracellular sodium, post-rest potentiation (PRP, and contraction force induced by caffeine. Results: In hyperthyroid animals, we observed decreased PRP at all rest times (p < 0.05, increased +df/dt and -df/dt (p < 0.001, low positive inotropic response to decreased concentration of extracellular sodium (p < 0.001, reduction of the maximum force in caffeine-induced contraction (p < 0.003, and decreased total contraction time (p < 0.001. The maximal contraction force did not differ significantly between groups (p = 0.973. Conclusion: We hypothesize that the changes observed are likely due to a decrease in calcium content in the sarcoplasmic reticulum, caused by calcium leakage, decreased expression of NCX, and increased expression of a-MHC and SERCA2.

    Full Text Available Since first reported in the late 1970s, there has been a steady but dramatic increase in the worldwide prevalence of hyperthyroidism in cats. It is now regarded as the most common feline endocrine disorder, with diabetes mellitus coming a close second. Not only is there evidence for an increased worldwide prevalence of feline hyperthyroidism, but also for geographical variation in the prevalence of the disease. Despite its frequency, the underlying cause(s of this common disease is or are not known, and therefore prevention of the disease is not possible. Due to the multiple risk factors that have been described for feline hyperthyroidism, however, it is likely that more than one factor is involved in its pathogenesis. Continuous, lifelong exposure to environmental thyroid-disruptor chemicals or goitrogens in food or water, acting together or in an additive fashion, may lead to euthyroid goitre and ultimately to autonomous adenomatous hyperplasia, thyroid adenoma and hyperthyroidism. This review aims to summarise the available published evidence for the changes observed in the worldwide prevalence of the disease, as well as risk factors that may contribute to development of hyperthyroidism in susceptible cats.

  5. Diagnosis of hyperthyroidism when serum-thyroxine alone is raised.

    1977-07-09

    31 patients admitted to hospital with different non-thyroidal intercurrent diseases were found to have raised total serum-thyroxine (T4) and free T4 together with normal serum-triiodothyronine (T3) concentrations. At admission none was clinically hyperthyroid. Patients were assigned to 3 groups according to clinical course and the laboratory findings. In the first group (14 patients) classic hyperthyroidism developed after recovery from the intercurrent disease. 11 out of these 14 patients had recently received iodine-containing preparations. In a second group (11 patients) the initially raised serum-T4 rapidly returned to normal with recovery from the non-thyroidal disease. In a third group (6 patients) serum-T4 concentrations remained raised well after recovery from intercurrent disease. In this group, there were 2 cases of transient iodine-induced (Jod-Basedow) hyperthyroidism in which raised serum-T4 returned spontaneously to normal after several months as iodine was eliminated. These results indicate that increase in serum-T4 with normal serum-T3 in patients with intercurrent systemic disease is not always the result of hyperthyroidism and in many cases probably reflects changes in peripheral metabolism of T4. It is suggested that careful clinical follow-up is needed in patients with raised serum-T4 and normal serum-T3 for the early detection and treatment of classic hyperthyroidism.

    Full Text Available Maternal Graves’ disease is relatively uncommon with an estimated incidence of 0.4%–1% of all pregnancies, but only 1–5% of newborns delivered to mothers with Graves’ disease develop overt clinical signs and symptoms of hyperthyroidism. Here, we describe a case of a 1380-gram female neonate who was born at 30-week gestation to a mother with Graves’ disease. Our patient presented with hyperthyroidism followed by transient hypothyroidism requiring treatment with levothyroxine. While hyperthyroid, she was treated with methimazole, iodine, and a beta-blocker. 20 days after the initiation of methimazole, she developed neutropenia. The neutrophil counts started to improve immediately after the initiation of the weaning of methimazole. To the best of our knowledge, this is the first case reported in the literature of methimazole induced neutropenia in a preterm infant being treated for neonatal Graves’ disease.

  8. Evidence for a possible calcium flux dependent cardiomyopathy in hyperthyroidism

    Barat, J.L.; Wicker, P.; Manley, W.

    1985-01-01

    This study was designed to test the hypothesis that the impaired functional cardiac reserve to exercise in hyperthyroidism is related to alterations in the regulation of calcium transport. In 2l hyperthyroid patients, the left ventricular ejection fraction (LVEF) was measured using equilibrium gated radionuclide angiocardiography at rest and during supine dynamic exercise. After a recovery period, the patients performed a second exercise study after random administration of Verapamil, a calcium entry blocker (11 pts), or propanolol, a beta adrenergic antagonist (10 pts) for comparison. The results showed i) normal resting LVEF with no significant change during exercise before any medication, ii) resting LVEF significantly decreased after Propanolol, and no significantly changed after Verapamil, iii) during exercise, significant increase of LVEF after Verapamil, and no significant change after Propanolol. These results are consistent with previous studies showing that abnormal change in LVEF during exercise in hyperthyroidism seems independent of beta adrenergic activation, and suggest a reversible functional cardiomyopathy dependent of calcium transporting systems

    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.

    Amioradone-induced hyperthyroidism is a common complication of amiodarone therapy. Although definitive interruption of amiodarone is recommended because of the risks of aggravation of the arrhythmias, some patients may require the reintroduction of amiodarone several months after normalisation of thyroid function. The authors undertook a retrospective study of the effects of preventive treatment of recurrences of amiodarone-induced hyperthyroidism with I131. The indication of amiodarone therapy was recurrent, symptomatic, paroxysmal atrial fibrillation in 13 cases and ventricular tachycardia in 5 cases (M = 14, average age 64 +/- 13 years). The underlying cardiac disease was dilated cardiomyopathy (N = 5), ischaemic heart disease (N = 3), hypertensive heart disease (N = 2), arrhythmogenic right ventricular dysplasia (N = 2) or valvular heart disease (N = 2). Two patients had idiopathic atrial fibrillation. An average dose of 576 +/- 184 MBq of I131 was administered 34 +/- 37 months after an episode of amiodarone-induced hyperthyroidism. Amiodarone was reintroduced in 16 of the 18 patients after a treatment-free period of 98 +/- 262 days. Transient post-radioiodine hyperthyroidism was observed in 3 cases (17%). Sixteen patients (89%) developed hypothyroidism requiring replacement therapy with L-thyroxine. There were no recurrences of amiodarone-induced hyperthyroidism. After 24 +/- 17 months follow-up, the arrhythmias were controlled in 13 of the 16 patients (81%) who underwent the whole treatment sequence. The authors conclude that preventive treatment with I131 is an effective alternative to prevent recurrence of amiodarone-induced hyperthyroidism in patients requiring reintroduction of amiodarone to control their arrhythmias.

    We investigated the long-term outcome of treatment in 159 patients with hyperthyroidism first seen between 1979 and 1992. Median duration of follow-up was 10 1\\/2 years. We also inquired into current practice for the follow-up of hyperthyroidism by other endocrinologists in Ireland. Seven cases of unrecognised hyperthyroidism (4 per cent) and one of unrecognised hypothyroidism were identified. Among patients with Graves\\' disease, of those treated with an antithyroid drug, 28 per cent were in remission, 68 per cent had relapsed and 4 per cent had become hypothyroid. Of those treated by sub-total thyroidectomy, 31 per cent were in remission, 19 per cent had relapsed, 19 per cent were hypothyroid and 31 per cent were sub-clinically hypothyroid. Among patients treated with radioiodine, 19 per cent were euthyroid, 3 per cent were still hyperthyroid and three-quarters had become hypothyroid. In contrast, after radioiodine for toxic nodular goitre, 63 per cent were euthyroid and only 32 per cent had become hypothyroid (Chi Squared v. Graves\\' disease, P = 0.001). Of 73 patients receiving thyroxine replacement, plasma TSH was normal in only 41 per cent, although 82 per cent of patients had been seen by the family doctor within the previous 12 months. Seven of 17 other endocrinologists undertook long-term follow-up of hyperthyroid patients in their specialist clinics but none was using a computerised system to co-ordinate this. The findings confirm that careful follow-up is required for all hyperthyroid patients. The family doctor is well positioned to undertake this, but education and auditing are required.

  13. The Incidence and Risk of Inducing Hyperthyroidism Following Amiodarone Treatment

    Full Text Available Introduction: Amiodarone, a frequently used antiarrhythmic drug in cardiology, is very efficient in the treatment of ventricular and supraventricular tachiarrithmyas. The iodine content of amiodarone is 39%. Its chemical structure is similar to tyrosine. It is estimated that 1-23% of patients treated with amiodarone can develop hyperthyroidism. The purpose of this study is to assess and monitor the incidence of hyperthyroidism induced by amiodarone in patients admitted for various types of cardiac dysrhythmias, considering that most of the patients included in the study came from an endemic goitre area.

    Full Text Available Cognitive and behavioral impairments are common in patients with abnormal thyroid function; these impairments cause a reduction in their quality of life. The current study investigates the decision making performance in patients with hyperthyroidism to explore the possible mechanism of their cognitive and behavioral impairments.Thirty-eight patients with hyperthyroidism and forty healthy control subjects were recruited to perform the Iowa Gambling Task (IGT, which assessed decision making under ambiguous conditions.Patients with hyperthyroidism had a higher score on the Zung Self-Rating Anxiety Scale (Z-SAS, and exhibited poorer executive function and IGT performance than did healthy control subjects. The patients preferred to choose decks with a high immediate reward, despite a higher future punishment, and were not capable of effectively using feedback information from previous choices. No clinical characteristics were associated with the total net score of the IGT in the current study.Patients with hyperthyroidism had decision-making impairment under ambiguous conditions. The deficits may result from frontal cortex and limbic system metabolic disorders and dopamine dysfunction.

    Full Text Available Due to the important role of thyroid disorders on reproductive health of the women of childbearing age, pregnancy outcome, fetal health, and neurodevelopment of the infant, providing comprehensive assessment of the treatments used for preventing hyperthyroidism and hypothyroidism seems to be essential. Therefore, evaluating the efficacy of different treatments of the thyroid disorders would be beneficial in better managing and controlling the disease during pregnancy. Hypothyroidism (a deficiency of thyroid hormone is a common thyroid disorder, which might increase the incidence rate of miscarriage, pre-eclampsia, placental abruption, and preterm delivery. Hyperthyroidism, which is not a common disorder during the pregnancy not only leads to similar adverse effects as hypothyroidism but also can result in stillbirth and intrauterine growth restriction. Levothyroxine is the preferred treatment of hypothyroidism and the only drug therapy recommended for treating hyperthyroidism during pregnancy. In this study, we aimed to briefly review the adverse effects of hyperthyroidism and hypothyroidism during pregnancy and review the effects of recent suggested treatments for controlling thyroid disorders on pregnancy outcomes.

    Aortic aneurysms are a rare condition in childhood and youth, etiology, evolution, natural progression and prognosis in pregnancy unknown. Hyperthyroidism occurs when there is a synthesis and/or excessive secretion of thyroid hormones during pregnancy poses difficulty for diagnosis. The new monitoring hemodynamics in pregnancy by transthoracic bioimpedance is a feasible alternative, noninvasive and real-time hemodynamic monitoring pregnant women. Primiparity 18, is referred to present tachycardia, hyperthyroidism is diagnosed and drug treatment is initiated with antithyroid from week 14.1 echocardiogram reports bivalve aortic aneurysm in the sinus of Valsalva is performed. He was determined to continue the same under strict hemodynamic and fetal monitoring. Pregnancy concludes at the end obtained through the abdomen, at 40.4 weeks, with male product, weight 2250 g, Apgar 9/9, with growth restriction type I. The mother and baby were discharged simultaneously without complications. The hyperdynamic state of pregnant patients in hyperthyroidism and aneurysms is complex and potentially complicable is why the hemodynamic patient monitoring is essential to detect changes in it that endanger the life of the binomial to this condition. Heart disease and hyperthyroidism, in this case, consistent with a fetal complications level is described as intrauterine growth restriction, however narrow and multidisciplinary monitoring and timely interventions binomial lead to satisfactory results in this case.

    Hyperthyroidism in adolescents and children is a common endocrinium disorder, which disturbs the development of diverse body systems, especially of skeletal and central nervous systems. The patients with hyperthyroidism have a lower long-term, spontaneous remission of the disease. The majority of adolescents and children patients with hyperthyroidism have to receive an effective, safe therapy. Currently, there are three methods for treating hyperthyroidism. They include in antithyroid drugs (ATD), surgery and radioactive iodine ( 131 I) therapy. ATD always is the first line way to these patients with hyperthyroidism for endocrinologist yet. But the remission rate of hyperthyroidism for ATD is lower, the remission of hyperthyroidism also need spend longer time, and side effects of ATD are more common in adolescents and children than in adult. The success ratio and complications of surgery are mainly depended on the technic of surgeons, 131 I has been used as the treatment of hyperthyroidism for more than six decades. So far, there are still no enough evidences to show that the incidence of thyroid cancer and other malignant diseases, the patients fertility rate, rate of abortion and malformation of descendants in hyperthyroidism patients following 131 I were marked difference with that in other people. The remission rate of hyperthyroidism following 131 I was higher and its side effects were less. 131 I therapy can be the first choice to adolescents and children with hyperthyroidism who are no suitable to ATD therapy. Hypothyroidism is most often one outcome of pediatric patients with hyperthyroidism after 131 I therapy. Hence, the patients with hypothyroidism have to receive the replacement treatment of thyroxine. Since the development of adolescents and children are more dependent on thyroxine and adolescents and children are more sensitive to the radioactive rays than adults, it is more suitable to get ideal control with a relative lower dosage of mi to

  6. Misdiagnosis of Graves' Disease with Apparent Severe Hyperthyroidism in a Patient Taking Biotin Megadoses.

    2016-06-01

    Accurate immunoassays measuring minute quantities of hormones are the cornerstone of the practice of endocrinology. Despite tremendous advances in this field, novel pitfalls in these tests emerge from time to time. Oral biotin can interfere with immunoassays of several hormones. The purpose of this report is to relate an extreme case of such interference. A patient with progressive multiple sclerosis was found to have extremely elevated free thyroxine, triiodothyronine, and suppressed thyrotropin (TSH) levels. His TSH receptor binding inhibiting antibody level was also elevated. This constellation of laboratory findings suggested a diagnosis of severe Graves' disease. All of the assays yielding abnormal results employed the biotin-streptavidin affinity in their design. The patient had no symptoms of hyperthyroidism, and detailed review of his medications revealed intake of megadoses of biotin. Temporary discontinuation of biotin treatment resulted in complete resolution of the biochemical abnormalities. Non-physiologic biotin supplementation may interfere with several immunoassays, including thyroid hormones, TSH, thyroglobulin, and TSH receptor binding inhibiting antibody, leading to erroneous diagnoses. Questioning for biotin intake should be part of the evaluation for patients undergoing endocrine tests. Interruption of biotin supplementation for at least two days prior to biotin-sensitive tests should be sufficient to avoid major misdiagnoses.

    2007-01-01

    Previous studies have suggested that subclinical thyroid dysfunction, as manifested by abnormalities in thyroid-stimulating hormone (TSH) levels, are associated with detrimental effects on the cardiovascular system. Subclinical hypothyroidism is characterized by abnormal lipid metabolism, cardiac dysfunction, diastolic hypertension conferring an elevated risk of atherosclerosis, and ischemic heart disease. Similarly, patients with subclinical hyperthyroidism have nearly 3 times the likelihood of atrial fibrillation over a 10-year follow-up interval, raising the question of whether patients with subclinical hyperthyroidism should be treated to prevent atrial fibrillation. A single measurement of low serum TSH in individuals aged 60 years or older has been reported to be associated with increased mortality from all causes and in particular from circulatory and cardiovascular disease in a 10-year follow-up study. Subclinical thyroid dysfunction is currently the subject of numerous studies and remains controversial, particularly as it relates to cardiovascular morbidity and mortality and clinical applications.

    2004-01-01

    To investigate the possibility of 131 I therapy hyperthyroidism in adolescent, 117 adolescent patients treated with 131 I are analyzed retrospectively. In the first treatment of 131 I, 76 patients gain with euthyroidism (65.0%), 28 patients have remission (23.9%), 13 patients have hypothyroidism (11.0%), the total efficacy is 88.9%. The administered dose to the patients with younger than 14 years is significantly lower than the patients aged from 15 years to 18 years. There is no significantly difference in cure rate or incidence of hypothyroidism between the two groups. The second treatment may improve the cure rate and not exert any significant impact to the incidence of hypothyroidism. Therefore, 131 I treatment hyperthyroidism in younger is efficacious, inexpensive and safe. The dosages given to patients are different between age groups. (authors)

    Development of hyperthyroidism following primary hypothyroidism is uncommon, and only a few documented cases have been reported. Alterations in thyroid-stimulating hormone receptor antibodies in serum are currently considered to play the main role in the pathophysiology, but the exact mechanism is still unknown. Here, we report the case of a 60-year-old man with disturbed consciousness due to hyponatremia. Thyroid function tests showed primary hypothyroidism with a high anti-microsomal antibo...

    Full text: Since the year 1953, when iodine prophylaxis was introduced in Slovenia, several epidemiological studies confirmed the existence of mild iodine deficiency on the whole territory of Slovenia. In January 1999 the implementation of higher iodine content (25 mg of KI or 32 mg of KIO 3 ) was recommended and since then the increased incidence of thyrotoxicosis was observed. Here we present 5-year follow-up data of the incidence of hyperthyroidism due to thyroid autonomy and Graves' disease. We estimated incidence rates from 1997 to 2001 for hyperthyroidism due to thyroid autonomy and Graves' disease among 1000000 people, living in the area of Ljubljana. We assumed that most cases were seen and treated in the Outpatient Department for thyroid diseases of Department for Nuclear Medicine of University Medical Centre Ljubljana. Immediately after correction of iodine deficiency, the incidence of hyperthyroidism due to thyroid autonomy rose almost twice in 1999 (320 cases in 1999 compared to 173 cases in 1997), but afterwards the incidence slightly decreased (240 cases in 2000). Similarly, the incidence of Graves' disease rose in 1999 (267 cases in 1999 compared to 237 in 1997) and in contrast to thyroid autonomy the incidence further increased in the following years (337 in 2000 and 246 in the first half of 2001). The increased incidence of hyperthyroidism due to thyroid autonomy and Graves' disease after elevation of iodine prophylaxis in Slovenia is comparable with data in some other endemic areas. Those data indicate that stepwise supplementation is preferable to immediate corrections. However, we believe that iodine prophylaxis is reasonable and justified and to reassess the iodine nutrition status we plan a follow up evaluation in year 2002. (author)

  16. Effect of 131I on the anemia of hyperthyroidism

    Perlman, J.A.; Sternthal, P.M.

    1983-01-01

    Data from the National Thyrotoxicosis Therapy Follow-Up Study (NTTFS) are presented here to document the existence of anemia in hyperthyroidism, a mild and reversible anemia that is simultaneously ameliorated with reversal of the hyperthyroid state. Among 20,600 women entered into the NTTF study with no previous history of hematological disorders, the prevalence of anemia was found to range from 10-15%, appearing to be higher in those selected for treatment with 131I when compared to those selected for surgery. An attempt is made to verify the recent hypothesis that thyroid hormone levels in the supraphysiologic range may suppress erythrogenesis. Two statistically significant regression models are consistent with a hypothesis of thyrotoxic bone marrow suppression. However, both associations are weak enough to suggest that some other physiologic improvement underlies the amelioration of anemia when hyperthyroidism is reversed. The degree of improvement in hematological status is similar for women in both treatment groups. Among 4464 women for whom serial hematological tests are obtained, over 3/4 of anemic patients are no longer anemic after an average 6.2 yr of follow-up. Clinicians are reassured that radioactive iodine exposure causes no further insult to the bone marrow, no matter what the cumulative dosage. The highly fractionated low dose bone marrow exposures to radiation account for the minimal hematological risks of 131I treatment

    Full text: Radioiodine is being increasingly used in the treatment of hyperthyroidism. The primary reasons for choosing radioiodine therapy are its effectiveness, ease of administration, relatively low cost and paucity of side effects. Here we presented our experiences and outcome of radioiodine therapy in hyperthyroidism in a divisional referral centre.We retrospectively analyzed 203 patients receiving radioiodine therapy for hyperthyroidism in Centre for Nuclear Medicine and Ultrasound, Khulna during the period from July 1994 to June 2004. All the patients had clinical signs and symptoms of hyperthyroidism as well as elevated triiodothyronine (T 3 ), thyroxine (T 4 ) and suppressed thyroid stimulating hormone (TSH). T 3 , T 4 and TSH were done in all cases. Radionuclide scan and ultrasound of thyroid gland, radioactive iodine uptake (RAIU), thyroid microsomal antibody (TMAb) and fine needle aspiration cytology (FNAC) was done in selected cases. We assessed all patients prior to radioiodine therapy. Elderly patients and all those with cardiac complications and severe hyperthyroidism were pretreated with a short course of antithyroid drug in full dosages until they were clinically and biochemically euthyroid. Ninety five patients were on antithyroid medication (Neomercazole) prior to radioiodine therapy. Antithyroid medication were stopped 3 days before radioiodine therapy and restarted 3 days later and continued for 1 to 2 months depending on patient's symptoms. The rest of the patients received either no treatment or beta-blocker prior to radioiodine therapy. Menstrual history was taken in female patients and pregnancy was excluded by ultrasonography in doubtful cases before administering radioiodine. The likely consequences of the treatment were fully explained to the patients and attendants, the usual precautions for radiation protection of the public and the necessity of the follow-up were discussed and verbal consent was taken before administering radioiodine

  18. Hepatotoxicity in hyperthyroid patient after consecutive methimazole and propylthiouracil therapies

    2018-01-01

    Full Text Available Methimazole (MMI and propylthiouracil (PTU are widely used antithyroid drugs (ATD that have been approved for the treatment of hyperthyroidism. Hepatotoxicity may be induced by these drugs, though they exert dissimilar incidence rates of hepatotoxicity and, possibly, with different underlying pathogenic mechanisms. We report the case of a 55-year-old woman with no relevant medical history diagnosed with hyperthyroidism due to Graves’ disease, who developed two episodes of acute hepatitis concurrent with the consecutive administration of two different ATDs, first MMI and then PTU. Given the impossibility of administering ATDs, it was decided to perform a total thyroidectomy because the patient was found to be euthyroid at that point. Pathological anatomy showed diffuse hyperplasia and a papillary thyroid microcarcinoma of 2 mm in diameter. Subsequent clinical check-ups were normal. This case suggests the importance of regular monitoring of liver function for hyperthyroid patients. Due to the potential severity of this side effect, it is recommended to determine baseline liver function prior to initiation of treatment.

    1989-01-01

    During 1977, 246 hyperthyroid patients were seen in our departments, 140 (57%) with nonimmunogenic hyperthyroidism (NIH)--101 with a toxic adenoma (TA) and 39 with multifocal functional autonomy (MFA). All patients but one could be followed over 9 yr, 101 after 131I treatment (RIT), another 29 after surgery (S). Ten patients were left untreated. Thirty-four treated (24%) patients died, none as a result of thyroid or post-treatment complications. There was no hyperthyroidism later than 9 mo after therapy. Only 1% (RIT) and 24% (S) were hypothyroid 1 yr after treatment. But 19% of all treated NIH patients were hypothyroid after 9 yr or at the time of their death, 12% after RIT and 41% after S. The cumulative hypothyroidism incidences 1.4%/yr for RIT and 2.2%/yr for S, were not significantly different. Out of the five survivers without RIT or S, two TA patients were hypothyroid. The effect of RIT on goiter related loco-regional complications was not worse than after S. We conclude that RIT is the treatment for NIH, leaving surgery for exceptional cases

    Full Text Available Background/Aim. The Fracture Risk Assessment Tool (FRAX® score is the 10-year estimated risk calculation tool for bone fracture that includes clinical data and hip bone mineral density measured by dual-energy x-ray absorptiometry (DXA. The aim of this cross-sectional study was to elucidate the ability of the FRAX® score in discriminating between bone fracture positive and negative pre- and post-menopausal women with subclinical hyperthyroidism. Methods. The bone mineral density (by DXA, thyroid stimulating hormone (TSH level, free thyroxine (fT4 level, thyroid peroxidase antibodies (TPOAb titre, osteocalcin and beta-cross-laps were measured in 27 pre- and post-menopausal women with newly discovered subclinical hyperthyroidism [age 58.85 ± 7.83 years, body mass index (BMI 27.89 ± 3.46 kg/m2, menopause onset in 46.88 ± 10.21 years] and 51 matched euthyroid controls (age 59.69 ± 5.72 years, BMI 27.68 ± 4.66 kg/m2, menopause onset in 48.53 ± 4.58 years. The etiology of subclinical hyperthyroisims was autoimmune thyroid disease or toxic goiter. FRAX® score calculation was performed in both groups. Results. In the group with subclinical hyperthyroidism the main FRAX® score was significantly higher than in the controls (6.50 ± 1.58 vs 4.35 ± 1.56 respectively; p = 0.015. The FRAX® score for hip was also higher in the evaluated group than in the controls (1.33 ± 3.92 vs 0.50 ± 0.46 respectively; p = 0.022. There was no correlations between low TSH and fracture risk (p > 0.05. The ability of the FRAX® score in discriminating between bone fracture positive and negative pre- and postmenopausal female subjects (p < 0.001 is presented by the area under the curve (AUC plotted via ROC analysis. The determined FRAX score cut-off value by this analysis was 6%, with estimated sensitivity and specificity of 95% and 75.9%, respectively. Conclusion. Pre- and postmenopausal women with subclinical hyperthyroidism have higher FRAX® scores and thus

  3. Temporary internal pacing.

    2014-12-01

    Technology and insertion techniques for cardiac temporary internal pacing have experienced a remarkable development over the last few years. Despite this fact, the procedure continues to have potentially fatal associated complications. Temporary internal pacing is indicated for the treatment of bradyarrhythmias or tachyarrhythmias refractory to conventional treatment, or arrhythmias causing cardiovascular or clinical instability of the patient. On the other hand, the indications of temporary cardiac pacing are far less well defined than those of permanent pacing. Since the decision of implementing temporary pacing is complex and delicate, it should always be carefully considered, and over-indication should be avoided. We must base these decisions on robust knowledge of the arrhythmias that may benefit from temporary internal pacing, and should also acquire the habit of considering external temporary pacing among other less aggressive treatments, and to make the best use of new technologies such as echocardiography that add accuracy to the procedure.

    The purpose of this study is to survey the attitude and knowledge of radiation and radioiodine treatment in hyperthyroid patients. One-hundred-eighty-seven hyperthyroid patients who were sent for radioactive iodine treatment at Division of Nuclear Medicine, Department of Radiology, Faculty of Medicine Siriraj Hospital were requested to fill the questionnaires before and after receiving the information about radioiodine treatment. The questionnaires consisted of 15 questions of which the first five were about the attitude to radiation and radioiodine treatment. The rest was about an information on hyperthyroidism and radioiodine treatment. For data analysis, firstly the percentage of correct answer of each question was calculated and compared between pre-and post-test. Secondly all patients were categorized into 2 groups according to their education: up to high school, and undergraduate or higher. The attitude and the understanding about radioiodine treatment were analyzed in each group. If the average percentage was greater than 80, patients has positive attitude of good understanding. The results showed that post-test gives higher percentages of correct answers for all questions with an average of 24.6% improvement. For up to high school group, the attitude improved from 81.6% to 98.6% and the understanding about radioiodine treatment improved from 92.2% to 100%. Similarly, for the undergraduate or higher group, the attitude improved from 87% to 97.8% and the understanding about radioiodine treatment was 100% for both pre- and post-intervention. It may be concluded that our education intervention is informative and improves the patients, attitude and understanding about radiation

    We report the case of a 20-year-old Japanese woman with no psychiatric history with apparent dissociative symptoms. These consisted of amnesia for episodes of shoplifting behaviors and a suicide attempt, developing together with an exacerbation of Graves' hyperthyroidism. Patients with Graves' disease frequently manifest various psychiatric disorders; however, very few reports have described dissociative disorder due to this disease. Along with other possible causes, for example, encephalopathy associated with autoimmune thyroid disease, clinicians should be aware of this possibility. Copyright © 2014 Elsevier Inc.

    Since 1993, outpatient radioiodine therapy has been available in Hungary. The reported study evaluated the efficacy of outpatient radioiodine treatment in subjects with hyperthyroidism. The data on 238 patients with Graves' disease and 123 patients with thyroid autonomy were analyzed retrospectively. All patients were treated within the period 1994 - 1999. The activities of radioiodine were calculated individually. The dose applied in Graves' disease was 150 Gy, and that in thyroid autonomy was 300 Gy. The efficacy of the treatment was evaluated 3,6 and 12 months after radioiodine therapy. In patients with persistent hyperthyroidism, repeated therapy was performed. Overall,the radioiodine therapy was successful in 84% of the Graves' disease patients. In thyroid autonomy, treatment with 300 Gy was successful in 79% of the patients. The efficacy of radioiodine treatment was similar to the results of one-dose application. It was concluded that radioidine therapy with an absorbed dose of 150 Gy in Graves' disease and with an absorbed dose of 300 Gy in thyroid autonomy proved successful by the method applied. (author)

    A retrospective cohort study of women treated for hyperthyroidism at the Mayo Clinic between 1946 and 1964 was conducted to determine if 1,005 women treated with ( 131 I) were at increased risk of breast cancer compared with 2,141 women traced, and a response (death certificate or questionnaire) was received for 99% of the traced women. The average duration of follow-up was 15 years for the 131 I-treated women and 21 years for women treated surgically. No increased risk of breast cancer was observed in the 131 I-treated women (adjusted relative risk . 0.8). No patterns were found of increased breast cancer risk by age at first treatment, by time since treatment, or by total exposure to 131 I. Failure to detect an increased risk of breast cancer in the 131 I-treated women was attributed to the moderately low doses from 131 I therapy and the relatively small number of exposed women. The study also failed to find any increased risk of breast cancer associated with hyperthyroidism

    Sleepwalking is a disorder characterized by complex motor behaviors arising from slow wave sleep usually occurring in children. The adult onset of sleepwalking suggests the presence of an external precipitating factor leading to the occurrence of the disorder. Hyperthyroidism has been reported to be the possible cause of sleepwalking in a few cases. We present the case of a 36-year-old man who reported a sudden appearance of nocturnal episodes of sleepwalking. He underwent a complete video polysomnography (VPSG), which showed a polygraphic pattern arising from stage N3 sleep related to the presence of simple motor behaviors. Routine blood tests showed a mild hyperthyroidism. After 4 months of thyrostatic treatment, the patient reported no more sleepwalking events. A VPSG performed at the last follow-up showed the absence of pathological electroclinical events arising from stage N3 sleep. Therefore, we hypothesize that there is a link between sleepwalking and thyroid dysfunction in our patient. © 2018 American Academy of Sleep Medicine

    To evaluate the therapeutic effect of 131 I in treatment of patients with hyperthyroidism and analysis the factors that influence the effect, 230 cases of hyperthyroidism were treated with 131 I, and were followed-up at 1.5, 3, 6, 12 months and even longer time after 131 I radiotherapy. The serum levels of FT3, FT4 and TSH were detected in all cases. The results showed that 181 patients were cured (78.6%), 22 patients were improved (9.5%), 23 cases developed early hypothyroidism(10.0%),and 4 cases developed later hypothyroidism. 12 cases in 27 patients with hypothyroidism treated with thyroxin were recovered, but the other 15 cases need to be given permanent treatment. The factors which influence 131 I radiotherapeutic effect include the patient age, course of disease,application of ATD, size and quality of thyroid, and the level of thyroid hormone. The patients should be followed up to prevent occurrence of hypothyroidism. The early hypothyroidism should be treated in order to decrease the permanent hypothyroidism rate. (authors)

I distinguish between temporary migrations where the return time is exogenous, and temporary migrations where the migrant chooses when to return. I then illustrate the consequences both types of temporary migration have for migrants' behaviour (as opposed to a permanent migration). If migrations are non-permanent, then this has also consequences for the way empirical models need to be specified. The p...

    Objective: Hyperthyroidism is frequently associated with pronounced neuropsychiatric symptoms such as impulsiveness, irritability, poor concentration, and memory impairments. Functional neuroimaging has revealed changes in cerebral metabolism in hyperthyroidism, but regional changes in cortical morphology associated with specific neurological deficits have not been studied so far. To investigate the pathophysiology underlying hyperthyroid-associated neural dysfunction, we compared grey matter volume (GMV) between adult hyperthyroid patients and matched healthy controls using voxel-based morphometry (VBM). Materials and methods: High resolution 3D T1-weighted images were acquired by 3T MRI from 51 hyperthyroid patients and 51 controls. VBM analysis was performed using SPM8. Correlations between regional GMV and both serum free thyroid hormone (TH) concentrations and disease duration were assessed by multiple regression analysis. Results: Compared to controls, GM volumes in the bilateral hippocampus, parahippocampal gyrus, calcarine, lingual gyrus, and left temporal pole were lower and bilateral supplementary motor area GMV higher in hyperthyroid patients. Serum free triiodothyronine (FT3) concentration was negatively correlated with the normalized regional volume (NRV) of the left parahippocampal gyrus and serum free thyroxine (FT4) concentration negatively correlated with the NRV of the left hippocampus and right parahippocampal gyrus. Disease duration was negatively correlated with the NRV of the left hippocampus, bilateral parahippocampal gyrus, and left temporal pole. Conclusion: Hyperthyroid patients exhibited reduced GMV in regions associated with memory, attention, emotion, vision, and motor planning. Negative correlations between GMV and both free TH and disease duration suggest that chronic TH elevation induces abnormalities in the adult cortex.

    Since zinc mediates the effects of many hormones or is found in the structure of numerous hormone receptors, zinc deficiency leads to various functional impairments in the hormone balance. And also thyroid hormones have important activity on metabolism and feeding. NPY and leptin are affective on food intake and regulation of appetite. The present study is conducted to determine how zinc supplementation and deficiency affect thyroid hormones (free and total T3 and T4), melatonin, leptin, and NPY levels in thyroid dysfunction in rats. The experiment groups in the study were formed as follows: Control (C); Hypothyroidism (PTU); Hypothyroidism+Zinc (PTU+Zn); Hypothyroidism+Zinc deficient; Hyperthyroidism (H); Hyperthyroidism+Zinc (H+Zn); and Hyperthyroidism+Zinc deficient. Thyroid hormone parameters (FT 3 , FT 4 , TT 3 , and TT 4 ) were found to be reduced in hypothyroidism groups and elevated in the hyperthyroidism groups. Melatonin values increased in hyperthyroidism and decreased in hypothyroidism. Leptin and NPY levels both increased in hypo- and hyperthyroidism. Zinc levels, on the other hand, decreased in hypothyroidism and increased in hyperthyroidism. Zinc supplementation, particularly when thyroid function is impaired, has been demonstrated to markedly prevent these changes.

    TRH stimulation tests and T 3 suppression tests were done in 13 patients with clinically suspected mild or early hyperthyroidism who were all conventional thyroid function tests gave results within the accepted normal range. The results were as follows 1) 6 patients with normal T 3 suppression test revealed normal TRH stimulation test and could be easily diagnosed as euthyroidism 2) 7 patients with abnormal T 3 suppression test exhibited no TSH response to TRH stimulation test and could be easily diagnosed as hyperthyroidism. The TRH stimulation test is a single, sensitive and reliable test of thyroid function and can well replace T 3 suppression test in the diagnosis of marginal hyperthyroidism

    The study was to evaluate factors affecting outcome of 131 I therapy in hyperthyroidism for optimizing the method. Data from 213 patients who received 131 I treatment from July 2003 to July 2005 in our department were retrospectively analyzed. Factors possibly contributing to the outcome of the 1311 therapy were analyzed, including gender, age, history of antithyroid drag, thyroid volume, duration of disease and radioactive iodine uptake rate. Multivariate analysis was done. The rates of euthyroidism and hypothyroidism were 69% and 8.5%, respectively, after one time 131 I therapy. Multivariate analysis of the patients showed no statistically significant factors affecting the outcome of 131 I therapy. The study showed that 131 I dose can be directly calculated, and this simplifies the dose-determined method and individualizes the therapy. (authors)

  6. Development of Hyperthyroidism Following Primary Hypothyroidism: A Case Report

    Full Text Available Development of hyperthyroidism following primary hypothyroidism is uncommon, and only a few documented cases have been reported. Alterations in thyroid-stimulating hormone receptor antibodies in serum are currently considered to play the main role in the pathophysiology, but the exact mechanism is still unknown. Here, we report the case of a 60-year-old man with disturbed consciousness due to hyponatremia. Thyroid function tests showed primary hypothyroidism with a high anti-microsomal antibody titer (1:6,400. The patient experienced weight loss and exophthalmos 6 years later. Serum thyroid hormone levels were increased and thyroxine treatment was discontinued, but the patient remained thyrotoxic 2 months later. 131I thyroid uptake was 40.9% at 24 hours, and bilateral thyroid lobes were not enlarged with diffuse radioactivity. Six months later, the patient was still thyrotoxic and therapy with methimazole 10 mg/day was started. He is now taking methimazole and is euthyroid.

    Full Text Available Osteoporosis in men is an important public health problem, and its prevalence is increasing as the population ages. Although it is traditionally considered as a women’s health issue, osteoporosis-related mortality and morbidity rates are higher in men. Although the lifetime risk of the hip fracture is lower in men than women, men are twice as likely to die after a hip fracture. All men diagnosed with osteoporosis should be evaluated for secondary causes of bone loss, such as hypogonadism, the use of corticosteroid, smoking, excessive alcohol consumption, low calcium intake, vitamin D deficiency and hypothyroidism. Here, we aimed to present a male patient in whom osteoporotic a vertebral fracture was detected and who was diagnosed with hyperthyroidism.

  8. TSI assay utilization: impact on costs of Graves' hyperthyroidism diagnosis.

    Thyroid-stimulating immunoglobulins (TSIs) are autoantibodies that bind to the thyroid-stimulating hormone (TSH) receptor on thyroid cells, resulting in Graves' disease (GD), the most common cause of hyperthyroidism. Recently published guidelines recognize the value of anti-TSH receptor antibodies, and a TSI test with high sensitivity and specificity for GD, recently cleared by the US Food and Drug Administration, is now available. Despite this, existing diagnostic algorithms for hyperthyroidism do not currently include TSI testing except in specific cases like pregnancy. The objectives of this analysis are to understand whether incorporating a test that specifically detects TSIs into existing algorithms results in cost savings and reduces time to diagnosis for payers and managed care organizations. An evidence-based economic model was developed to determine the average time to diagnosis and annual costs associated with various diagnostic algorithms for GD in a population of 100,000 managed care enrollees. Diagnostic algorithms used in current practice and hypothetical algorithms that include the TSI test were identified using published clinical guidelines and interviews with practicing endocrinologists. The model estimates costs of current and TSI test-based diagnostic algorithms using payment amounts for laboratory tests, procedures, and physician visits. Compared with non-TSI algorithms, 100% use of algorithms that include the TSI test result in 46% faster time to diagnosis and generate 47% overall cost savings due in large part to reductions in costly procedures and specialist office visits. Incorporation and early utilization of the TSI in vitro diagnostic test into current diagnostic algorithms confers cost savings and shortens time to diagnosis.

    Since 1942, therapy with radioiodine (Na 131 I) has gained a major role in the treatment of benign thyroid disorders, notably hyperthyroidism caused by Graves' disease or toxic multi nodular goiter. The very large series of patients treated so far offer the opportunity for an assessment of both benign and malignant side effects. Hyperthyroidism is sometimes observed after radioiodine therapy due to radiation induced thyroid hormone or by an immunological mechanism. Despite the numerous attempts to design dosage schedules aiming at euthyroidism, hypothyroidism occurs in the majority of patients throughout life. Transient hypothyroidism may be observed within the first year after therapy and is caused by an immunological mechanism. Radioiodine therapy in Graves' disease may induce or worsen ophthalmopathy, which can be prevented by steroids effectively. Hypoparathyroidism and hyperparathyroidism have been reported after radioiodine therapy but probably do not exceed the normal incidence. Sialitis is commonly observed but mostly in patients treated with radioiodine for thyroid cancer. There are no indications for induction of genetic abnormalities after radioiodine therapy although no definite conclusion can be reached. Much attention has been paid to malignant disease. In very large series, no effects of radioiodine therapy on survival have been observed. Some studies report an increased relative risk for certain types of cancer (notably thyroid cancer, stomach cancer, bladder and kidney cancer or hematological malignancies). However, these observations were not confirmed by other large studies, so that no definite conclusion with respect to risk for certain types of malignant disease can be drawn. However, radioiodine therapy for benign thyroid disorders has generally considered safe and without major side effects, hypothyroidism being the most frequent one

    Thyrotoxic periodic paralysis (TPP) is an endocrine disorder presenting with proximal motor weakness, typically greatest in the lower extremities, hypokalemia, and signs or laboratory findings consistent with hyperthyroidism. The incidence of TPP is highest in Asian males. This is a case report of a 30-year-old male active duty Soldier who presented to the emergency department complaining of several recent episodes of lower extremity paralysis. The patient underwent a workup which included serum and cerebrospinal fluid studies, and was found to be hypokalemic and hyperthyroid. Following consultation with neurology, the patient was admitted to the medicine service and treated for thyrotoxic periodic paralysis with potassium replacement and treatment of his hyperthyroidism. Since achieving a euthyroid state, he has had no recurrences of TPP. This disease should be considered in patients presenting with symmetric motor weakness and hypokalemia, whether or not symptoms of hyperthyroidism are elicited during the review of systems.

    Ventricular arrhythmias occurs in 20-50% of patients supported with left ventricular assist devices (LVAD). Ventricular arrhythmias are well tolerated with LVAD support but long-term consequences include worsening right ventricular function. Management of ventricular arrhythmias in LVAD patients includes use of antiarrhythmic agents or ablation. Amiodarone has been used a first-line agent to treat ventricular arrhythmias post-LVAD implantation. Chronic treatment with amiodarone for arrhythmias can result in hyperthyroidism and hypothyroidism in 5-10% of patients. Hyperthyroidism is known to cause endothelial dysfunction, alterations in coagulation, and fibrinolytic pathways favoring hypercoagulable state. We describe two cases of left ventricular assist device (LVAD) thrombosis potentiated by amiodarone-induced hyperthyroidism (AIT) and discuss pathophysiological mechanisms for hypercoagulable state induced by hyperthyroidism.

    Hyperthyroidism is a common side effect encountered in patients prescribed long-term amiodarone therapy for cardiac arrhythmias. We previously studied 354 patients prescribed amiodarone in whom the occurrence of hyperthyroidism was associated with major adverse cardiovascular events including heart failure, myocardial infarction, ventricular arrhythmias, stroke and even death [1]. We now present a case of amiodarone-induced hyperthyroidism complicated by isolated right heart failure and pulmonary hypertension that resolved with treatment of hyperthyroidism. Detailed quantitative echocardiography enables improved understanding of the haemodynamic mechanisms underlying the condition.

    According to recent studies, the risk for thyroid cancer is not increased after radioiodine treatment in patients with hyperthyroidism. Only the risk of cancer of the stomach seems to be increased slightly in patents treated with I-131 because of functional autonomy. However, the risk for gastric cancer is not increased after higher activities of I-131 because of thyroid cancer. There is no increased risk for genetic abnormalities after radioiodine treatment of hyperthyroidism. (orig.) [de

    To exploit the antiarrhythmic effect of amiodarone when patients develop the side effect of thyrotoxicosis three patients with hyperthyroidism induced by amiodarone were given simultaneously 1 g potassium perchlorate a day for 40 days and a starting dose of 40 mg methimazole a day while they continued to take amiodarone. As hyperthyroidism might have recurred after potassium perchlorate treatment was stopped the dose of methimazole was not reduced until biochemical hypothyroidism (raised thyr...

    This study was conducted to determine the effect of thyroid hormone on opiate receptor ligand-binding and pain sensitivity. Specific opiate receptor-binding was performed on brain homogenates of Swiss-Webster mice. There was a significant increase in {sup 3}H-naloxone-binding in thyroxine-fed subjects (hyperthyroid). Scatchard analysis revealed that the number of opiate receptors was increased in hyperthyroid mice (Bmax = 0.238 nM for hyperthyroid samples vs. 0.174 nM for controls). Binding affinity was unaffected (Kd = 1.54 nM for hyperthyroid and 1.58 nM for control samples). When mice were subjected to hotplate stimulation, the hyperthyroid mice were noted to be more sensitive as judged by pain aversion response latencies which were half that of control animals. After morphine administration, the hyperthyroid animals demonstrated a shorter duration of analgesia. These findings demonstrate that thyroxine increases opiate receptor number and native pain sensitivity but decreases the duration of analgesia from morphine.

    The objective of the present experiment was to study the effect of hyperthyroidism on male gonadal functions and oxidant/antioxidant biomarkers in testis of adult rats. Induction of hyperthyroidism by L-thyroxine (L-T4, 300 μg kg(-1) body weight) treatment once daily for 3 or 8 weeks caused a decrease in body weight gain as well as in absolute genital sex organs weight. The epididymal sperm counts and their motility were significantly decreased in a time-dependent manner following L-T4 treatment. Significant decline in serum levels of luteinising hormone, follicle stimulating hormone and testosterone along with significant increase in serum estradiol level was observed in hyperthyroid rats compared with euthyroid ones. Significant increase in malondialdehyde and nitric oxide concentration associated with significant decrease in superoxide dismutase and catalase activity was also noticed following hyperthyroidism induction. Both reduced glutathione content and glutathione peroxidase activity were increased in hyperthyroid rats compared with control rats. Marked histopathological alterations were observed in testicular section of hyperthyroid rats. These results provide evidence that hypermetabolic state induced by excess level of thyroid hormones may be a causative factor for the impairment of testicular physiology as a consequence of oxidative stress. © 2014 Blackwell Verlag GmbH.

    Amiodarone-induced hyperthyroidism is relatively common in iodine-deficient regions. Two types have been described: type I, caused by increased synthesis and release of thyroid hormone in individuals with underlying thyroid disease, can be treated with antithyroid drugs or radioiodine; and type II, a destructive thyroiditis responsive to corticoid therapy but not to antithyroid drugs. It can be difficult to distinguish between the two types, and cases of mixed types have been reported. to assess the usefulness of thyroid scintigraphy in amiodarone-induced hyperthyroidism. 27 consecutive patients (13 females) with amiodarone-induced hyperthyroidism. Mean age was 65 years (range: 39-89). All patients underwent 99mTc-pertechnectate thyroid scintigraphy and were classified according to the qualitative estimation of radiotracer uptake: type I (increased / normal uptake): 9 patients, all of whom responded to antithyroid drugs or radioiodine, except one patient with sub-clinical hyperthyroidism who received no therapy; type II (very low or undetectable uptake): 13 patients, 11 of whom responded to discontinuation of amiodarone or prednisone therapy (2 patients). Hyperthyroidism was resistant in 2 patients and required antithyroid drugs or potassium perchlorate; mixed type (low uptake but with underlying thyroid pathology): 5 patients, with variable evolution; all needed antithyroid drugs, one required subtotal thyroidectomy, and another radioiodine treatment. thyroid scintigraphy can establish the correct therapeutic approach in most cases of amiodarone-induced hyperthyroidism, making it essential in the clinical management of these patients.

    1995-01-01

    Radioiodine (131I) treatment was started in Iceland in 1960 and the same formula has been used from the beginning to calculate the doses of radioactivity aiming for 70 Gy irradiation of the gland. In the present investigation we studied 468 patients who were treated over a period of 19 years (1973-1991). About 90% of the patients had Graves' disease (GD), 9% toxic adenoma but less than 1% toxic multinodular goiter. Approximately 70% of the GD patients became hypothyroid (subclinical hypothyroidism included) within the first year after a single radioiodine treatment and about 80% were hypothyroid four years after treatment with no significant increase after that. By contrast, only one of 15 patients with toxic adenoma became hypothyroid after a single treatment. For both groups the recurrence rate of hyperthyroidism was approximately 20%. The formula used for dose calculation in this study for GD patients does not seem to be satisfactory. The smaller glands are getting to much irradiation and the larger glands to little as can be seen by the frequency of hypothyroidism in the smaller glands and recurrences (continuing hyperthyroidism) in the larger glands after one treatment (table V). In 1993 blood samples were obtained from a sample group (n=103) of once 131I treated GD patients and measurements were done for serum TSH, T4 and free T4. One third of the patients who were considered euthyroid, and therefore not taking T4, were found to be hypothyroid with elevated TSH and low FT4 and one third of those taking T4 seemed to be overtreated with elevated FT4 and decreased TSH levels. It is concluded that the results of the radioiodine treatment for GD are unsatisfactory and need to be changed, either by adjusting the present regimen so that radiation is decreased in the smaller glands but increased in the larger ones or alternatively, by increasing the radiation dose to all the glands rendering the majority of the patients quickly hypothyroid followed by replacement

    To explore the relationship between the bone mineral density (BMD) and serum PTH, BGP and CT levels in patients with hyperthyroidism. The serum levels of BGP, CT and PTH in 167 patients with hyperthyroidism and 58 normal controls were determined by RIA. The results showed that the serum CT levels and BMD in patients with hyperthyroidism were significantly lower than those in the control group (P<0.01). The serum levels of PTH and BGP in patients were significantly higher than those in the control group (P<0.01). The BMD in patients with hyperthyroidism was related to the serum levels of PTH, BGP and CT. (authors)

    Objectives: To evaluate short-term (6 month) efficacy of fixed-dose (555 MBq, 15 mCi) approach in the treatment of Graves' hyperthyroidism and analyze the relationship between clinical outcome (hyperthyroidism, hypothyroidism, and euthyroidism) and variances (patient age, thyroid weight, absorbed activity per gram of thyroid tissue, and radioactive iodine uptake value). Methods: 38 patients of Graves' hyperthyroidism were treated with 555MBq of radioactive iodine (in the form of capsule). Follow-up was done 3 and 6 months post therapy and the following clinical outcome was monitored: persistent hyperthyroidism, hypothyroidism, and euthyroidism. Statistical analysis was performed with SPSS software (version 11.5). P<0.05 was taken as indicating a statistically significant effect. Results: Of the 38 subjects, 14 (36.8%) were identified as euthyroidism, 18 (47.4%) hypothyroidism, and 6 (15.8%) hyperthyroidism. Cure rate (euthyroidism+hypothyroidism) was 84.2%. Statistical analysis revealed that there is a statistically significant difference of absorbed activity per gram of thyroid tissue and thyroid weight (F=17.639, P=0.000; F=28.453, P=0.000), but there is no statistically significant difference in terms of patient age and RAIU (F=1.375, P-0.266; F=2.453, P=0.101) among euthyroidism, hypothyroidism, and hyperthyroidism patients. Conclusion: We concluded that fixed-dose approach is very effective in the quickly restoration of thyroid function. There is a statistically significant difference of absorbed activity per gram of thyroid tissue and thyroid weight, but there is no statistically significant difference in terms of patient age and RAIU among euthyroidism, hypothyroidism, and hyperthyroidism patients.

    The purpose of this study was to develop guidelines based on patient measurements as to when iodine-131- (131I) treated hyperthyroid patients may resume close personal contact. External exposure rates were measured on 59 patients using an ionization survey meter in the upright position. The initial measurement was recorded within 20 min post-dose administration at one meter. Exposure rates were measured 2-11 days post-dose administration at 1, 0.6, and 0.3 meters from the patient's thyroid. In the administered dose range of 3 to less than 12 mCi of 131I, all 40 patients measured less than or equal to 2.0 mR/hr at one meter on Day 0, and 25 patients (25/29) were less than or equal to 2.0 mR/hr at 0.6 meter on Days 2-4.

    Studies of serum thyroid-stimulating antibody (TSAb) levels and other indices of thyroid status were performed on patients with Graves' disease currently on antithyroid drugs, freshly diagnosed patients with Graves' disease and relatives of patients with Graves' disease. Of 25 patients with Graves' disease currently on anti-thyroid drugs, 12 were initially TSAb-positive and 13 TSAb-negative. At the end of medication 6 initially TSAb-positive patients were still positive and all soon relapsed; all initially TSAb-negative patients were still negative. Of 18 patients TSAb-negative at the end of medication 16 remained negative, while 2 became positive and relapsed. All of 15 freshly diagnosed patients with Graves' disease were TSAb-positive. All of 79 relatives of patients with Graves' disease were TSAb-negative, regardless of their thyroid status as judged by other indices. It is concluded that TSAb levels as measured by the direct in vitro thyroid stimulation assay of McKenzie and Zakarija provide a sensitive index for prognosis of the clinical course of hyperthyroidism in Graves' disease. Earlier reports of TSAb or long-acting thyroid stimulator (LATS) activity in the sera of euthyroid relatives of such patients were not confirmed

    Purpose: To evaluate the efficacy of 131 I-iodine treatment of hyperthyroidism in children and adolescents. Methods: Twenty-nine, patients aged 11-18 years (mean 15.9±2.32 years old), with hyperthyroidism received 131 I-iodine treatment in a dose of 25-90μCi/g (median 50μCi/g) of thyroid. Of the 29 patients, 3 patient required 2 doses, 14 received ATD therapy before 131 I, 11 patients suffered from TAO(thyroid associated ophthalmopathy). The total maximum and minimum doses were 15 and 1.6 mCi respectively. Results: All patients treated with 131 I-iodine, follow-up after the most recent treatment (median 14, range 4 to 60 months), 15 patients were euthyroid, 5 suffered from late-onset hypothyroidism, 9 were still hyperthyroidism, but their symptoms and signs of hyperthyroidism were improved or markedly. Of the 16 patients with TAO, TAO in 11 patients disappeared or were improved, TAO in 5 patients didn't or mildly change. The size of thyroid in all patients had largely been reduced. Conclusions: 131 I-iodine is effective for initial treatment of hyperthyroidism, the treatment of medical treatment failures and the patients with TAO in children and adolescents. (authors)

    Apium graveolens is one of the well-known herbs used for the treatment of different; however, allergic reactions have been reported after its use. This report aimed to demonstrate the A. graveolens induced hyperthyroidism after its oral consumption for weight loss. Mr. A, 48-year-old, with no history of any thyroid diseases, was diagnosed with hyperthyroidism due to daily consumption of 4 g of dried celery leaves for 45 days. After cessation of consumption and treatment with methimazole, the symptoms remitted. Then, the medication was discontinued when the lab tests and ultrasound were normal and indicated the patient's definite recovery. In 2 months follow up of, he was normal and thyroid-stimulating hormone (TSH), T4, T3, anti-TSH receptor, anti thyroperoxidase and antithyroglobulin were in normal ranges. Hyperthyroidism may be induced by consumption celery. Although many studies have reported side effects such as allergic reactions for this herb, this is the first report of hyperthyroidism induced by celery in which the patient recovered after discontinuing the medication. Therefore, it can be assumed that celery induces hyperthyroidism as a side effect of this herb if it is used for a long term.

    Ballism is a very rare presentation in association with hyperthyroidism. We describe a 22-year-old lady with episodes of recurrent ballism and hyperthyroidism. A 22-year-old lady was admitted to Neurology department because of sudden development of vigorous involuntary movement and dysarthria. She was diagnosed as hyperthyroidism at the age 12 and treated irregularly. She arrived at the emergency room because of sudden onset of involuntary movement. Computed tomography (CT) scan and Magnetic Resonance Imaging (MRI) of brain was normal. Serum levels of thyroid hormone were increased (Free T4 3.15 ng/dl; normal range 0.93-1.71 ng/dl), whereas thyroid-stimulating hormone (TSH) was undetectable. The thyroid gland was diffusely enlarged and exophthalmos was found. She had been given antithyroid medication from local clinic but medicated irregularly. Technetium thyroid scan reveals diffusely enlarged thyroid with increased radioactivity. Radioiodine uptake in 24 hours was 71 %. Brain perfusion SPECT using Tc-99m ECD reveals asymmetrical perfusion pattern in basal ganglia. Brain PET using F-18 FDG reveals increased metabolism at both caudate nucleus and putamen. She was treated with radioiodine and involuntary movement was improved. There is only few report on ballism associated with hyperthyroidism and no report on functional brain imaging. Brain perfusion SPECT and FDG PET may give useful information about functional status of brain in patients with ballism associated with hyperthyroidism in case of normal anatomical finding on CT/MRI.

    To investigate whether the incidence of hypothyroidism after 131 I treatment of patients with hyperthyroidism is lower in Japan than in the Western countries, the results of treatment were retrospectively analyzed with patients to whom 131 I had been administered, individually estimating radiation dose to the thyroid. A total of 1119 patients treated at five clinics from 1955 to 1967 were evaluated in 1969. The average initial dose of 131 I in the present series was 5.6 m Ci and 6340 rads to the thyroid, and this was an average dose used in Japan for the corresponding period. The results of treatment were analyzed by the one-dose group (625 cases) and the repeat-dose group (494 cases), as well as for total cases. The incidence of hypothyroidism was calculated by the life table method and, of the total cases, the incidence was 9.4, 18, and 26%, 5, 10, and 12 years respectively after the initial treatment. The rate of hypothyroidism was generally a little higher and the increment by the end of 5 years was steeper in the one-dose group than in the repeat-dose group. In reviewing the results between the Western countries and Japan, including the present series, fairly good correlation was found between radiation dose to the thyroid in the initial dose and the incidence of hypothyroidism 5 years after the initial dose. The lower incidence of hypothyroidism in Japan appeared due mainly to a lower radiation dose to the thyroid in the initial treatment. Radiation doses to the thyroid glands of patients who became hypothyroid in the one-dose group were 7220 +- 2810 rads and ranged from less than 3000 rads to more than 14000 rads. Of the patients in the one-dose group, whose thyroid received a definite dose ranging from 6000 to 8000 rads, those with less thyroid enlargement were more apt to develop hypothyroidism. (auth.)

    Hyperthyroidism (H) has been implicated as a primary cause of decreased exercise tolerance. To our knowledge, analysis of respiratory gas exchange, an efficient noninvasive method in evaluating cardiopulmonary capacity, has not been performed in patients with H. Using cardiopulmonary exercise testing, 12 consecutive women with Graves' H were examined and controlled in euthyroidism (E). Eighteen women with E, in whom cardiac catheterization had ruled out heart disease, served as control subjects (C). The ventilatory anaerobic threshold was determined by means of the V-slope method. Ergometry was performed with patients in a semisupine position using a continuous ramp protocol of 20 W/min. Echocardiography at rest was performed in all patients. In patients with H, heart rate at rest was higher than in patients with E (p lower increase between rest and anaerobic threshold compared with E patients (p = 0.007) and C (p = 0.009). Work rate was reduced (H, 50% vs E, 70%; p = 0.038). In H patients, the anaerobic threshold occurred at 59.6% of maximal oxygen uptake and 72% in E patients, respectively (p = 0.024). In H patients, the linear regression of the heart rate to oxygen uptake ratio showed a reduced slope in comparison with E patients (p = 0.001) and C (p = 0.004). In patients with H, a reduced tidal volume (p = 0.021) and an increased respiratory rate (p = 0.003) in comparison to patients with E were demonstrated. Echocardiographically, H patients had an increased ejection fraction (p = 0.008) and a higher cardiac index (p = 0.008) in comparison with E patients. Analysis of respiratory gas exchange showed marked alterations of cardiopulmonary exercise capacity in H patients, which are reversible in E patients. The impaired chronotropic response during exercise might be the primary limiting factor of reduced work capacity in patients with H.

    BACKGROUND AND OBJECTIVE: Hyperthyroid patients treated with radioiodine have increased morbidity and mortality from cerebrovascular events. This risk has until now has been attributed to the hyperthyroidism. However, radioiodine therapy of benign thyroid diseases exposes the carotid arteries...... to radiation and is capable of inducing atherosclerosis. The objective of the study was to elucidate whether ionizing radiation from radioiodine might contribute to cerebrovascular morbidity. METHODS: In a retrospective register cohort study, 4000 hyperthyroid and 1022 euthyroid goitre patients treated...... with radioiodine between 1975 and 2008 were matched 1:4 on age and sex with random controls. The cohort was followed from the date of treatment until hospitalization due to cerebrovascular event, death, 20 years of follow-up or March 2013.

    Objective: To investigate the application value of urine brain natriuretic peptide (BNP) level in 131 I treatment of hyperthyroid heart disease. Methods: One hundred and eleven hyperthyroidism patients who received 131 I therapy were divided into two groups, hyperthyroidism group (51 cases) and hyperthyroid heart disease group (60 cases), and 30 healthy subjects as control. Sixty patients in the hyperthyroid heart disease group all received ultrasonic cardiogram. The hyperthyroid heart disease group was divided into two subgroups according to New York Heart Association (NYHA) functional classification (hyperthyroid heart disease A subgroup and hyperthyroid heart disease B subgroup). The urine and serum BNP level and serum free triiodothyronine (FT 3 ), free thyroxine (FT 4 ) level were measured through chemiluminescence before and after therapy. Results: The urine and serum BNP level before 131 I therapy of the hyperthyroid heart disease group were significantly higher than those of hyperthyroidism group (serum: t=8.98 and 9.52, both P<0.01; urine: t=10.83 and 12.73, both P<0.01) and the control group (serum: t=8.97 and 9.52, both P<0.01; urine: t=9.21 and 5.64, both P<0.01). The urine and serum BNP level before and 6, 12 months after 131 I therapy of the hyperthyroid heart disease A subgroup were significantly higher than those of hyperthyroid heart disease B subgroup (serum: t=5.98, 5.87 and 6.35, all P<0.01; serum: t=4.33, 4.09 and 5.02, all P<0.01). The urine level of BNP was gradually increased with the severity of cardiac insufficiency and it was positively correlated with the serum level of BNP (r=0.829, P<0.01), the NYHA functional classification (r=0.751, P<0.01) and the serum level of FT 3 and FT 4 (FT 3 : r=0.635, P<0.01; FT 4 : r=0.672, P<0.01). Conclusions: The urine BNP level of hyperthyroid heart disease patient increased with the severity of cardiac insufficiency. The urine BNP level could accurately reflect cardiac function of hyperthyroid heart

    Objectives This study sought to evaluate how Australian veterinarians approach management and monitoring of feline hyperthyroidism and compare these results with a similar survey recently performed in the UK. Methods An invitation to complete an online survey was sent to veterinarians in all states and territories of Australia. The survey comprised questions relating to management of hyperthyroidism, use of antithyroid drugs vs radioiodine treatment vs surgical thyroidectomy, in addition to demographic information for respondents. Results A total of 546 clinicians completed the survey. The most commonly preferred treatments for long-term management of feline hyperthyroidism were antithyroid medications (305/546; 56%) and radioiodine (210/546; 38%), with substantially more respondents selecting radioiodine when cost was removed as a consideration (425/546; 78%). However, most respondents had treated or referred few cases for radioiodine (median 2). Most veterinarians (500/546; 92%) used antithyroid medications either long term or prior to definitive treatment of hyperthyroidism. For medical management, 45% (244/546) of veterinarians used twice-daily carbimazole. Half of respondents (274/546) aimed to maintain the total thyroxine concentration anywhere within the laboratory reference interval in hyperthyroid cats without chronic kidney disease. Blood pressure monitoring was uncommon. Surgical thyroidectomy was rarely performed. Conclusions and relevance Radioiodine was more frequently preferred by Australian veterinarians compared with those in the UK, likely associated with greater availability, reduced cost and shorter hospitalisation times in this jurisdiction, although antithyroid medications were the most frequently used treatment modality. Barriers remain to its utilisation, however, including perceived cost, misconceptions with regard to expected success rate and accessibility. Recent changes to recommendations on the management and monitoring of hyperthyroid

    Generalized weakness, intermittent dysphagia, and a 40-pound weight loss developed in an elderly man over a six-month period. Examination revealed weakness, atrophy and fasciculations of extremity musculature, pseudobulbar speech, hyperactive upper extremity reflexes, and extensor toe signs without sensory loss. Results of electrodiagnostic studies were consistent with an axonal polyneuropathy. Endocrinologic results were compatible with hyperthyroidism. Radioiodine therapy resulted in resolution of clinical neurologic symptoms and signs within seven months. This case illustrates a previously undescribed concurrence of hyperthyroid associated polyneuropathy and pyramidal tract dysfunction that led to an initial clinical diagnosis of amyotrophic lateral sclerosis.

    Full Text Available The study was focused on determining the impact of hyperthyroidism due to Graves’ disease on the state of skeletal system in women. According to the ultrasound densitometry data, pathological changes in the state of skeletal system were revealed in both reproductive age and menopause. Hyperthyroidism had especially pronounced effect on the state of skeletal system in menopausal women, who were characterized by the presence of severe osteopenia and systemic osteoporosis (75 and 25 %, respectively. These findings indicate the need for treatment of osteoporotic syndrome, which complicates Graves’ disease course in women and increases the risk of pathological fractures.

    A study of 50 patients with hyperthyroidism was conducted to evaluate the effect of preoperative administration of Lugol's iodine solution on thyroid blood flow. Highly significant reductions in diameter, time-averaged velocity, and volume flow of the superior thyroid artery were demonstrated after administration of Lugol's solution. The Duplex ultrasound scanning used in this study is a noninvasive, inexpensive, accurate, and reproducible technique suitable for analysis of thyroid blood flow in hyperthyroidism. On the basis of current ultrasonographic results and low postoperative morbidity in patients, Lugol's solution is well tolerated and may be recommended for use before thyroidectomy, especially for diffuse toxic goiters and Graves disease.

    Full Text Available Background: Different types of hyperthyroidism are treated differently. The correct diagnosis enables the adequate treatment. Clinical experiences suggest that free thyroxine (fT4 to free triiodothyronine (fT3 ratio is different for different types of hyperthyroidism. Considering the paucity of literature data on the topic our aim was to evaluate the role of the serum fT4 to fT3 (fT4/fT3ratio in diagnostics of various types of hyperthyroidism.Methods: In retrospective clinical study we included 440 consecutive subjects, examined between February and August 2010, 350 females and 90 males aged between 15 and 97 years, among them 225 healthy subjects (HS, 80 patients with Graves' disease (GD, 48 with toxic adenoma (TA, 61 patients with hyperthyroid Hashimoto’s thyroiditis (HHT, 17 with subacute thyroiditis (ST, and 9 patients with iodine-induced hyperthyroidism (IIH. Thyrotropin (TSH, fT4, fT3 and thyroid autoantibodies were measured. The fT4/fT3 ratio was calculated.Results: The fT4/fT3 ratio was significantly different for various disorders causing hyperthyroidism (p<0.001. Compared with the fT4/fT3 ratio in HS (2.86±0.52, the ratio was significantly higher in HHT and ST (3.27±0.72 and 3.31±0.54, respectively, p<0.001 for both. In GD, the fT4/fT3 ratio was the lowest (2.55±0.58 and in IIH the highest (5.13±1.97. Both ratios significantly differed from the ratio in HS (p<0.001 for both and in other hyperthyroid patients (p<0.001 for both. In patients with TA, the fT4/fT3 ratio was similar as in HS (2.85±0.71 (p=0.085.Conclusion: The fT4/fT3 ratio is different in various types of hyperthyroidism and therefore represents a useful tool in the diagnostic procedure.

    Full text: Purpose/Background Subclinical hyperthyroidism (Sh) is defined as a biochemical abnormality characterized by a subnormal level of TSH with otherwise normal thyroid tests (F T 3 , F T 4 ) and no clinical symptoms. There are only a small number of cross-sectional studies on the prevalence of Sh. With the improvement of the sensitivity of TSH assay, it has become possible to survey the clinical significance of Sh. With regard to both Sh and subclinical hypothyroidism, discussions are being focused on such as the necessity of treatment. In order to elucidate the clinical significance of Sh, examination data of A-bomb survivors in Hiroshima and Nagasaki were analyzed. Subjects and Method Between 2000 and 2003, of 4,090 A-bomb survivors (1,352 males and 2,738 females with average age of 70.7), 75 individuals (1.83%) with Sh were found who had normal Free T 4 (0.71∼1.51 ng/dL) and TSH<0.45 m U/L. Analysis was limited to those who had not taken antithyroid drugs or thyroxin, and the Sh group (n=35; 9 males and 26 females) was compared with a control group with TSH:0.45∼4.5 m U/L (Group C; N=3,243; 1,109 males and 2,134 females). Result: Nine individuals had TSH<0.1 m U/L. In the Sh group, six individuals were TPO antibody-positive (17%) and 14 were TG antibody-positive (40%); hence, TG antibody-positive was significantly greater in number (p=0.0096). Hematological biochemical tests showed no significant difference between the two groups. Electrocardiograms indicated that more individuals had atrial fibrillation [p=0.028; Odds ratio (OR)=3.98; 95% Confidential interval (CI)=1.2-13.7] or ventricular premature contraction [p=0.016; OR=3.29; 95% CI=1.3-8.6] in the Sh group. In terms of the presence or absence of diabetes, dyslipidemia, hypertension, and hyperuricemia, there was no difference between the two groups. One individual from the Sh group was confirmed to have Graves' disease two years later. Conclusion: Since more individuals in the Sh group were

    Full Text Available Ghrelin is a peptide of 28 amino acids that transmits appetite related signals from peripheral organs to the brain. The main source of ghrelin is stomach. The regulation of ghrelin secretion is still unknown. The finding that fasting and food intake, respectively increase and decrease the secretion of ghrelin suggests that this hormone may be a bridge connecting somatic growth with energy metabolism and appears to play an important role in the alteration of energy homeostasis and body weight in pathophisiological conditions. The purpose of this study was the evaluation of gastric ghrelin immunoreactivity and ghrelin plasma concentration in male Wistar rats with hyperthyroidism. Experimental model of hyperthyroidism was induced by intraperitoneal injection of levothyroxine at the dose of 80 microg/kg daily over 21 days. At the end of experiment the animals were anaesthetized, blood was taken from abdominal aorta to determinate plasma ghrelin concentration by RIA and then the animals underwent resection of distal part of stomach. Immunohistochemical study were performed using monoclonal specific antybodies against ghrelin. Hyperthyroidism was a reason of increase of gastric mucosal ghrelin - immunoreactivity, accompanied by a significant decreased of ghrelin plasma concentration. Those observations may indicate, that chronic administration of L-thyroxine cause the change of ghrelin plasma concentration in rats, probably via direct influence on gastric X/A-like cells, but this effect is not responsible for hyperphagia associated with hyperthyroidism.

    To determine whether beta blockade protects against the acceleration of lipid peroxidation in hyperthyroid rat soleus (slow-oxidative) muscle, in vivo chronic (3 weeks) effects of 3 beta blockers with different ancillary properties on mitochondrial oxidative enzymes, antioxidant enzymes, and thiobarbituric acid-reactive substances were investigated. The rats were rendered hyperthyroid by the administration of thyroxine and treated simultaneously with either carteolol (a nonselective blocker with partial agonist activity; 30 mg/kg/day), atenolol (a beta 1-selective blocker; 50 mg/kg/day), or arotinolol (a nonselective blocker with weak alpha-blocking action; 50 mg/kg/day) over a 3 week period. Hyperthyroidism induced tachycardia, an increase in the mitochondrial oxidative enzymes, manganese (mitochondrial) superoxide dismutase and thiobarbituric acid-reactive substances, and a decrease in the other antioxidant enzymes. The tachycardia was alleviated completely by either atenolol or arotinolol, but partially by carteolol. Arotinolol, but neither carteolol nor atenolol, inhibited the increase in oxidative enzymes and thiobarbituric acid-reactive substances. The levels of antioxidant enzymes were minimally affected by the beta-blocker treatment. Beta 2-, and possibly alpha- as well, but not beta 1-, blockade suppressed mitochondrial hypermetabolism and protected against peroxidative injury in the hyperthyroid soleus muscle. Partial agonist activity was not beneficial.

    The ongoing management of low, intermediate and high-level nuclear waste is an unresolved issue for humanity, not least because the time-frames in question when dealing with the hazards of radioactive wastes, range from as little as a few tens of years to more than 100 000 years. It is from this starting point that we are beginning the development of an ambitious multifaceted artwork aiming to help us consider our relationship with deep-time and our nuclear legacy. The expressed aim of Temporary Index is to raise general awareness about these long-term management issues, and in doing so, to embed this knowledge into our collective cultural memory so as to transmit useful information about our nuclear waste into the future. We wish to create a series of decorative, real-time numeric counters based on the probabilistic decay (including decay of daughter products) of existing nuclear waste that we identify from the earliest weapons' development programmes in the United States right through to contemporary wastes being produced by nuclear energy production today across the world. Each display will countdown in seconds, showing the time remaining before the given item of waste (or a particular site) is considered safe to humans. A hypothetical example of one counter could be a bottle of sludge containing plutonium discovered in 2004 during an attempted clean-up of the Hanford nuclear site in Washington State, United States. Another example might be the geological storage facility for vitrified nuclear waste at Horonobe in Japan, should it be established in the future. Accident sites, such as Chernobyl or Fukushima Daiichi could also be tagged with counters, as could low-level waste (LLW) repositories such as the one at Drigg near Sellafield in the United Kingdom. Whatever the items identified and this will be a complex process requiring collaboration with experts in the field, it is important that a wide range of short- and long-term counters are established to

  14. Longstanding hyperthyroidism is associated with normal or enhanced intrinsic cardiomyocyte function despite decline in global cardiac function.

    Full Text Available Thyroid hormones (THs play a pivotal role in cardiac homeostasis. TH imbalances alter cardiac performance and ultimately cause cardiac dysfunction. Although short-term hyperthyroidism typically leads to heightened left ventricular (LV contractility and improved hemodynamic parameters, chronic hyperthyroidism is associated with deleterious cardiac consequences including increased risk of arrhythmia, impaired cardiac reserve and exercise capacity, myocardial remodeling, and occasionally heart failure. To evaluate the long-term consequences of chronic hyperthyroidism on LV remodeling and function, we examined LV isolated myocyte function, chamber function, and whole tissue remodeling in a hamster model. Three-month-old F1b hamsters were randomized to control or 10 months TH treatment (0.1% grade I desiccated TH. LV chamber remodeling and function was assessed by echocardiography at 1, 2, 4, 6, 8, and 10 months of treatment. After 10 months, terminal cardiac function was assessed by echocardiography and LV hemodynamics. Hyperthyroid hamsters exhibited significant cardiac hypertrophy and deleterious cardiac remodeling characterized by myocyte lengthening, chamber dilatation, decreased relative wall thickness, increased wall stress, and increased LV interstitial fibrotic deposition. Importantly, hyperthyroid hamsters demonstrated significant LV systolic and diastolic dysfunction. Despite the aforementioned remodeling and global cardiac decline, individual isolated cardiac myocytes from chronically hyperthyroid hamsters had enhanced function when compared with myocytes from untreated age-matched controls. Thus, it appears that long-term hyperthyroidism may impair global LV function, at least in part by increasing interstitial ventricular fibrosis, in spite of normal or enhanced intrinsic cardiomyocyte function.

    Full Text Available Background: Hyperthyroidism or thyrotoxicosis occurs due to excess release of thyroid hormone. These hormones regulate the body’s energy balance and have effects on adipokine level. There are several reports suggesting interrelation between adipokines (resistin and leptin with thyroid dysfunction. Objectives: This study was established to investigate the effect of thyroid hormones in hyperthyroidism state on the level of some adipokines, leptin and resistin; in comparison with control. Patients and Methods: The present study included 50 Iraqi female patients with hyperthyroidism with age ranged between 30-58 years and 30 healthy controls with age ranged between 30-53 years. Serum samples were collected from study groups. The levels of thyroid hormones (TSH, T4 and T3 were determined by using automated Chemiluminescence Immunoassay (CLIA analysis system. Detection of leptin hormone and resistin hormone levels in the serum were determined by an enzyme linked immunosorbent assay (ELISA kits. Results: The results revealed that serum leptin levels were significantly low (P<0.004 in hyperthyroid patient groups as compared to control, and there were significant negative correlations between T4 and leptin (P<0.0001; also, T3 and leptin (P<0.05. Resistin hormone level increased non-significantly (P˃0.05 than control level; and there was significant negative correlation between TSH and resistin (P<0.035. Conclusion: The study shows that there is complex interrelation between adipocytokines (leptin and resistin with thyroid gland and pituitary gland. Leptin levels were decreased in hyperthyroid patients than control and associated negatively with T4 and T3 levels, while resistin levels were increased non-significantly than control and associated negatively with TSH level. They affect each other in their physiological function in the human body.

    Thyroid hormone disorders have long been linked to depression, but the causal relationship between them remains controversial. To address this question, we established rat models of hypothyroidism using (131)iodine ((131)I) and hyperthyroidism using levothyroxine (LT4). Serum free thyroxine (FT4) and triiodothyronine (FT3) significantly decreased in the hypothyroid of rats with single injections of (131)I (5mCi/kg). These rats exhibited decreased depression-like behaviors in forced swimming test and sucrose preference tests, as well as decreased anxiety-like behaviors in an elevated plus maze. Diminished levels of brain serotonin (5-HT) and increased levels of hippocampal brain-derived neurotrophic factor (BDNF) were found in the hypothyroid rats compared to the control saline-vehicle administered rats. LT4 treatment reversed the decrease in thyroid hormones and depression-like behaviors. In contrast, hyperthyroidism induced by weekly injections of LT4 (15μg/kg) caused a greater than 10-fold increase in serum FT4 and FT3 levels. The hyperthyroid rats exhibited higher anxiety- and depression-like behaviors, higher brain 5-HT level, and lower hippocampal BDNF levels than the controls. Treatment with the antidepressant imipramine (15mg/kg) diminished serum FT4 levels as well as anxiety- and depression-like behaviors in the hyperthyroid rats but led to a further increase in brain 5-HT levels, compared with the controls or the hypothyroid rats. Together, our results suggest that hypothyroidism and hyperthyroidism have bidirectional effects on anxiety- and depression-like behaviors in rats, possibly by modulating hippocampal BDNF levels.

    Objectives The outcome of radioiodine therapy in hyperthyroid cats is suspected to be influenced by multiple factors. The degree of activity of the thyroid gland, represented by uptake of sodium pertechnetate or tracer activities of radioiodine by the thyroid gland on thyroid scintigraphy, has been suggested in the literature as one of those. Thyroid gland pertechnetate uptake can be represented by (semi-)quantitative factors such as the thyroid to salivary gland (T/S) ratio, the thyroid to background (T/B) ratio and the percentage technetium uptake by the thyroid glands (%TcU). The aim of this study was to investigate a possible relationship between these thyroid scan parameters and radioiodine therapy outcome. Methods Sodium pertechnetate thyroid scans of 75 hyperthyroid cats were retrospectively evaluated and statistical analysis was performed with and without correction for injected radioiodine activity. Three different background regions of interest (ROIs) were used to calculate the T/B ratio and %TcU: 'neck', 'circle' and 'copy ROI'. Results Higher T/S ratios were found to be significantly related to a persistent hyperthyroid outcome in both analyses. For the T/S ratio, a threshold value of 5.4 was determined, with a sensitivity of 73% and a specificity of 59%. An increased risk for persistent hyperthyroidism compared with a final euthyroid outcome with an increased T/B circle ratio was only found to be significant without correction for the activity of radioiodine administered. For the %TcU no statistical significance was reached. Regarding a low total thyroxine outcome, no significant relationships with any of the investigated parameters were found. Conclusions and relevance The findings of this study suggest that semi-quantification of thyroid gland uptake is best performed using the T/S ratio. A T/S ratio ⩾5.4 is a possible indicator for an increased risk of persistent hyperthyroidism.

    Full Text Available Many phocid seals are expert divers that remain submerged longer than expected based on estimates of oxygen storage and utilization. This discrepancy is most likely due to an overestimation of diving metabolic rate. During diving, a selective redistribution of blood flow occurs, which may result in reduced metabolism in the hypoperfused tissues and a possible decline in whole-body metabolism to below the resting level (hypometabolism. Thyroid hormones are crucial in regulation of energy metabolism in vertebrates and therefore their control might be an important part of achieving a hypometabolic state during diving. To investigate the effect of thyroid hormones on diving physiology of phocid seals, we measured oxygen consumption, heart rate, and post-dive lactate concentrations in five harbor seals (Phoca vitulina conducting 5 min dives on command, in both euthyroid and experimentally induced hyperthyroid states. Oxygen consumption during diving was significantly reduced (by 25 % in both euthyroid and hyperthyroid states, confirming that metabolic rate during diving falls below resting levels. Hyperthyroidism increased oxygen consumption (by 7-8 % when resting in water and during diving, compared with the euthyroid state, illustrating the marked effect of thyroid hormones on metabolic rate. Consequently, post-dive lactate concentrations were significantly increased in the hyperthyroid state, suggesting that the greater oxygen consumption rates forced seals to make increased use of anaerobic metabolic pathways. During diving, hyperthyroid seals also exhibited a more profound decline in heart rate than seals in the euthyroid state, indicating that these seals were pushed towards their aerobic limit and required a more pronounced cardiovascular response. Our results demonstrate the powerful role of thyroid hormones in metabolic regulation and support the hypothesis that thyroid hormones play a role in modulating the at-sea metabolism of phocid seals.

    Hypothyroidism is a common endocrine disease. The frequency of pregnancy loss in women with known hypothyroidism as opposed to women with a later diagnosis of hypothyroidism has not been evaluated and compared with other common endocrine diseases. Population-based cohort study using Danish nationwide registers. All pregnancies in Denmark, 1997-2008, resulting in live birth (n = 732 533), spontaneous abortion (n = 112 487) or stillbirth (n = 2937) were identified together with information on maternal hypothyroidism, hyperthyroidism and diabetes. Cox model was used to estimate adjusted hazard ratio (aHR) with 95% confidence interval (95%CI) for spontaneous abortion and stillbirth, reference: no hypo- or hyperthyroidism or diabetes (n = 824 310). We identified 4951 pregnancies where maternal hypothyroidism was diagnosed before the pregnancy (group 1) and 2464 pregnancies where maternal hypothyroidism was diagnosed in the 2-year period after the pregnancy (group 2). In group 1, 825 pregnancies (16·7%) resulted in spontaneous abortion which was more frequent than in nonexposed (13·2%), (aHR 1·19 (95%CI 1·12-1·27)), and of the same magnitude as in hyperthyroidism (17·2%, P = 0·5) and diabetes (17·5%, P = 0·2) diagnosed before the pregnancy. In group 2, the frequency was 12·2% (aHR 0·92 (0·84-1·02)). In group 2, 16 pregnancies (0·65%) resulted in stillbirth which was more frequent than in nonexposed (0·36%), (aHR 1·81 (1·11-2·97)), of the same magnitude as in hyperthyroidism (0·82%, P = 0·5) and less frequent than in diabetes (2·9%, P Hypothyroidism increased the risk of both early and late pregnancy loss as did hyperthyroidism and in particular diabetes. We hypothesize that undetected or insufficiently treated maternal disease in the pregnancy may be of causal importance. © 2016 John Wiley & Sons Ltd.

    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

    To examine the risk of disability pension and changes in labour market income in patients with hyperthyroidism. From a 5% random sample of the Danish population and twins from the Danish Twin Registry we identified 1942 hyperthyroid singletons and 7768 non-hyperthyroid (matched 1:4) controls as well as 584 same-sex twin pairs discordant for hyperthyroidism. Singletons and twins were followed for a mean of 9 years (range 1-20). Cox regression analysis was used to examine the risk of disability pension and a difference-in-differences model was used to evaluate changes in labour market income. Hyperthyroid individuals had an increased risk of receiving disability pension: hazard ratio (HR) was 1.88, (95% CI: 1.57-2.24). Subdividing as to the cause of hyperthyroidism did not change this finding: Graves' disease (GD) HR was 1.51 (95% CI: 0.87-2.63) and toxic nodular goitre (TNG) HR was 2.10 (95% CI: 1.02-4.36). With respect to labour market income, the income of hyperthyroid individuals increased on average 1189 € less than their controls (Pmarket income, were seen within monozygotic twin pairs discordant for hyperthyroidism. Hyperthyroidism is associated with severe work disability as reflected by an 88% increased risk of receiving disability pension and a significant loss of labour market income.

    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

    Objective: To analyze the radioactive 131 I dose of treatment in pediatric patients with Graves hyperthyroidism. Method: Fifty one pediatric patients with hyperthyroidism and 150 adult patients with hyperthyroidism were retrospectively analyzed, who were contraindicated or refractory for medical therapy and treated with 131 I in this study. All pediatric and adult patients treated with 131 I were divided into five groups according to the thyroid weight. Group 1: ≤30 g,Group 2: 31∼50 g, Group 3: 51∼70 g, Group 4: 71 ∼90 g and Group 5: >90 g. The pediatric patients were comparable to the adult patients in data distribution of the thyroid weight. All pediatric patients who were either contraindicated or refractory to antithyroid drugs treatment and adult patients received radioactive 131 I treatment with a dose of (2.41±0.71), (3.27±0.97) MBq/g thyroid tissue respectively. The total administrated doses of 131 I in all pediatric and adult patients were (224.36±130.10) MBq and (354.88 ±308.04) MBq respectively. All the pediatric and adult patients treated with 131 I were followed-up (median 32 months, range 24 to 83 months; median 23 months,range 15 to 62 months, respectively). The treatment results were divided into euthyroid, hyperthyroidism, late-onset hypothyroidism and relapsed. Results: The results by followed-up found that 16 and 65 patients became euthyroid, 22 and 56 patients developed late-onset hypothyroidism, 12 and 25 patients still had hyperthyroidism, 1 and 4 patients relapsed after radioiodine therapy in pediatric group and adult group who were treated with 131 I, respectively. The total efficiency was 98% and 97.3%, respectively. There were no statistical significance of treatment effect between pediatric and adult patients (χ 2 =0.058, P>0.05).

    The purpose of this study was to investigate the prevalence and risk of adhesive capsulitis among hyperthyroidism patients. The data were obtained from the Longitudinal Health Insurance Database 2005 (LHID 2005) in Taiwan, using 1 million participants and a prospective population-based 7-year cohort study of survival analysis. The ambulatory-care claim records of patients diagnosed according to the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes relating to hyperthyroidism between January 1, 2004 and December 31, 2007, were obtained. The prevalence and the adjusted hazard ratio (HR) of adhesive capsulitis among hyperthyroid patients and the control group were estimated. Of 4472 hyperthyroid patients, 162 (671/100,000 person-years) experienced adhesive capsulitis during the 24,122 person-year follow-up period. The crude HR of stroke was 1.26 (95% confidence interval [CI], 1.06 to 1.49), which was larger than that of the control group. The adjusted HR of developing adhesive capsulitis was 1.22 (95% CI, 1.03 to 1.45) for hyperthyroid patients during the 7-year follow-up period, which achieved statistical significance. The results of our large-scale longitudinal population-based study indicated that hyperthyroidism is an independent risk factor of developing adhesive capsulitis.

    The recent investigations point out the significant role of oxidative stress in the development of thyroid gland disease. The present study was designed to investigate the variation of oxidative stae in women with non-autoimmunological subclinical hyperthyroidism. The study was conducted on 20 females with non-autoimmunological subclinical hyperthyroidism and 15 healthy women. Manganase-containing superoxide dismutase (Mn-SOD) and extracellular superoxide dismutase (EC-SOD) plasma activity, and malondialdehyde (MDA) plasma concentration were measured. EC-SOD plasma activity was significantly higher in women with subclinical hyperthyroidism when compared with the control group (13.3 +/- 2.1 vs. 10.9 +/- 1.4 NU/ml; p < 0.05), unlike Mn-SOD (4.2 +/- 0.5 vs. 4.0 +/- 1.0 NU/ml). MDA plasma concentration increased significantly in women with subclinical hyperthyroidism (3.5 +/- 1.2 vs. 2.0 +/- 0.6 micromol/l; p < 0.05). The increased EC-SOD plasma activity may reflect disturbances of oxidative state in subclinical hyperthyroidism. Parallel increase of MDA plasma concentration may indicate enhancement of lipid peroxidationin in patients with subclinical hyperthyroidism.

    The half-time values of tritiated water were explored in eleven hyperthyroid patients and in two hypothyroid ones. For reasons of comparability the numbers are expressed in days per square meter (d/m/sup 2/) of body surface. Against the estimated 5.4d/m/sup 2/ in normal subjects, the hyperthyroids reflected 3.9+-0.66 and the two determinations of hypothyroids were 6.42 and 7.13, respectively. During the study neither diagnostic nor therapeutic procedures were ever postponed. The half-time values are not representative of extreme conditions in hyper- or hypothyroids, but are sufficiently clear to indicate well-defined differences from normal people. The total exposure to radiation for the exploratory procedure was minimal, estimated at less than 12 mrem for the normal standard man.

    A nine-year-old cat with symptoms of a distinct hyperthyroidism was presented at the University Hospital of the RWTH Aachen. The clinical symptoms as well as the diagnostic procedures performed at the hospital confirmed the diagnosis. After five weeks of thyreostatic medication a regular metabolism of the thyroid gland was established, followed by a radioiodine therapy with 70.3 MBq 131-iodine. Subsequently, the cat was hospitalized for two days before it could be released in good condition. Six weeks after treatment the former drastically reduced weight of the cat recovered to near normal. Even though the chemical analysis detected a discrete hyperthyroidism, clinical symptoms were no longer prominent. Three months after treatment, the final examination showed a regular metabolism of the thyroid gland without a specific thyroidal medication. The presented case illustrates that radioiodine therapy is a safe and efficient treatment of thyroidal dysfunctions in veterinary medicine. (orig.) [de

    Objective: To evaluate changes in clinical markers of unremitted hyperthyroidism patients after the first 131 I treatment. Methods: Forth eight unremitted hyperthyroidism patients were selected. Their thyroid function, the peak of 131 I uptake rate and thyroid weight before and after 131 I treatment were compared. Results: TT 3 , TT 4 , TSH were relatively stable and the peak of 131 I uptake rate and thyroid weight were reduced after 131 I treatment. Conclusions: Thyroid volume was reduced after 131 I treatment even if patients' clinical symptoms still existed; the peak of 131 I uptake rate was reduced after 131 I treatment, suggesting that their sensibility to 131 I decreased, so the absorbed dose should be adjusted when the 131 I dosage of second treatment is calculated

    Among present advances of surgical treatment of hyperthyroidism is the preoperative localization of hyper-functioning glands by preoperative and intraoperative scan, this later one by a special gamma probe. By the other hand, parathyroid cysts are rare; may be of functioning type or not, as well as the findings of 99mTc-MIBI, and the intraoperative use of gamma probe to assess all the possible sites where could be hyperproductive glands of parathyroid hormone. We describe features of management, safety, and administration of radiological agent during the immediate preoperative period, as well as use of gamma probe during intervention. Evolution over follow-up is reported. This case represents the third patient operated on from hyperthyroidism by radio-guided surgery in our center, which introduced this technique in our country.

    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

    Gastric bypass is increasingly used in morbidly obese patients to achieve significant reduction of body weight and fat mass and concurrent improvement in co-morbidities. We report the case of a 53-year-old male patient (141 kg, BMI 50 kg/m2), successfully treated by amiodarone for supraventricular arrythmia, who underwent Roux-en-Y gastric bypass (RYGBP). 6 months after surgery, he had lost 45% of his preoperative weight (44.8% of weight loss was lean mass) and developed amiodarone-induced subclinical hyperthyroidism. We hypothesize the following sequence of events: weight loss after RYGBP, therefore fat loss, decrease in distribution volume of amiodarone inducing iodine overload and hyperthyroidism, reinforcing weight loss and particularly loss of lean mass. This report emphasizes the importance of careful monitoring of weight and body composition changes after RYGBP. In this situation, checking thyroid status is recommended, especially when there is a history of thyroid disease or potentially toxic thyroid medication.

    This study aimed at assessing the incidence of pulmonary hypertension (PH) at newly diagnosed hyperthyroid patients and at finding a simple model showing the complex functional relation between pulmonary hypertension in hyperthyroidism and the factors causing it. The 53 hyperthyroid patients (H-group) were evaluated mainly by using an echocardiographical method and compared with 35 euthyroid (E-group) and 25 healthy people (C-group). In order to identify the factors causing pulmonary hypertension the statistical method of comparing the values of arithmetical means is used. The functional relation between the two random variables (PAPs and each of the factors determining it within our research study) can be expressed by linear or non-linear function. By applying the linear regression method described by a first-degree equation the line of regression (linear model) has been determined; by applying the non-linear regression method described by a second degree equation, a parabola-type curve of regression (non-linear or polynomial model) has been determined. We made the comparison and the validation of these two models by calculating the determination coefficient (criterion 1), the comparison of residuals (criterion 2), application of AIC criterion (criterion 3) and use of F-test (criterion 4). From the H-group, 47% have pulmonary hypertension completely reversible when obtaining euthyroidism. The factors causing pulmonary hypertension were identified: previously known- level of free thyroxin, pulmonary vascular resistance, cardiac output; new factors identified in this study- pretreatment period, age, systolic blood pressure. According to the four criteria and to the clinical judgment, we consider that the polynomial model (graphically parabola- type) is better than the linear one. The better model showing the functional relation between the pulmonary hypertension in hyperthyroidism and the factors identified in this study is given by a polynomial equation of second

    Full Text Available Abstract Background Anterior mediastinal masses are a rare but well documented finding in Graves disease. The vast majority of these lesions represents benign thymic hypertrophy and regress after treatment of the hyperthyroidism. A small percentage of these cases however represent neoplastic/malignant diseases which require further treatment. Cases 12 year old boy with one year history of refractory Graves disease was found to have an anterior mediastinal mass and underwent curative thyroidectomy for sustained hyperthyroidism. Cervical lymphadenopathy was detected during the procedure and biopsy was obtained. A 23 year old woman who presented with a one month history of hyperthyroid symptoms, was diagnosed with Graves disease and also was found to have an anterior mediastinal mass on imaging. Biopsy of the anterior mediastinal mass was obtained and subsequently the patient underwent robotic thymectomy. Histologic examination and immunophenotyping of the cervical lymph node in a 12 year old boy revealed neoplastic proliferation of T lymphoblasts diagnostic of T lymphoblastic leukemia/lymphoma. Examination of the anterior mediastinal mass biopsy in the 23 year old woman revealed type B1 thymoma which was confirmed after examination of the subsequent robotic thymectomy specimen. Conclusion This is the first reported case of T cell lymphoblastic lymphoma and the third reported case of thymoma associated with sustained hyperthyroidism due to Graves disease. These cases indicate that an anterior mediastinal mass in a patient with active Graves disease may be due to a neoplastic cause, which may require definitive treatment. Caution should be exercised when dismissing a mediastinal mass as benign thymic hyperplasia in patients with active Graves disease.

    Full Text Available We report here a unique case of methimazole (MMI-induced pancreatitis. To our knowledge, this is the sixth case reported in the literature and the first diagnosed in a patient with toxic multinodular goiter. A 51-year-old Caucasian female with a history of benign multinodular goiter and subclinical hyperthyroidism was started on MMI 10 mg orally daily. Three weeks later, she developed sharp epigastric pain, diarrhea, lack of appetite, and fever. Her lipase was elevated 5 times the upper limit of normal, consistent with acute pancreatitis. There was no history of hypertriglyceridemia, or alcohol abuse. Abdominal computed tomography was consistent with acute uncomplicated pancreatitis, without evidence of gallstones or tumors. MMI was discontinued, and her hyperthyroid symptoms were managed with propranolol. Her acute episode of pancreatitis quickly resolved clinically and biochemically. One year later, she redeveloped mild clinical symptoms of hyperthyroidism with biochemical evidence of subclinical hyperthyroidism. MMI 10 mg orally daily was restarted. Five days later, she experienced progressive abdominal discomfort. Her lipase was elevated 12 times the upper limit of normal, and the abdominal computed tomography was again compatible with acute uncomplicated pancreatitis. MMI was again discontinued, which was followed by rapid resolution of her pancreatitis. The patient is currently considering undergoing definitive therapy with radioactive iodine ablation. Our case as well as previous case reports in the literature should raise awareness about the possibility of pancreatitis in subjects treated with MMI in the presence of suggestive symptoms. If the diagnosis is confirmed by elevated pancreatic enzymes, the drug should be discontinued.

    Full Text Available Aim: Thyroid dysfunction is common among older people associated with morbidity and mortality. Overall, the most common cause of hyperthyroidism is Grave%u2019s Disease (GD. In the older population however, Toxic Multinodular Goitre (TMG is more common. Iodine is an essential molecule for thyroid hormone synthesis. This may be due to the presence of autonomic areas with a higher sensitivity to iodine in the thyroid gland. The aim of this study was to detect the etiology of hyperthyroidism among cases older than 60 years.Material and Method: The study included 100 patients %u226560 years or older with hyperthyroidism. Demographic and clinical features of the patients were recorded. All patients were tested for anti-thyroid autoantibodies and underwent thyroid ultrasonographic (USG and scintigraphic examination. Iodine exposure was detected in 24-hour urine specimens. Results: Eighty-one patients (81% had overt and the remaining 19 (19% had subclinical hyperthyroidism and the mean age was 70.48 ± 6.16 (range 60-88. Thirteen patients had recent exposure to iodine and 11 had Jod Basedow Phenomenon (JBP. The most common disease was TMNG (29.2% and 8 patients had no definitive diagnosis; they were designated nondiagnostic (ND. Discussion: This is the first study that investigates the causes of thyrotoxicosis amoung older people in our country. The results indicated that TMNG was the most common cause. JBP cases had a history of exposure to iodine. For this reason, radiocontrast use in older people should be carefully evaluated with this respect.

    Amiodarone is an iodinated antiarrhythmic agent that is effective in the treatment of atrial and ventricular arrhythmias. A number of side effects are seen, including pulmonary toxicity and thyroid dysfunction. A patient with both amiodarone-induced pneumonitis and hyperthyroidism who exhibited abnormal gallium activity in the lungs, as well as diffuse gallium uptake in the thyroid gland is presented. The latter has not been previously reported and supports the concept of iodide-induced thyroiditis with gallium uptake reflecting the inflammatory response.

    The prescription of synthesis anti thyroids allows to get a fast control of hyperthyroidism when the average time of curing after iodine 131 varies from 6 to 12 weeks, according to the level of radiation doses. It allows to treat the patients in euthyroidism and to avoid aggravation of thyrotoxicosis in the following of the iodine and is particularly useful for the old patients with a cardio vascular risk

    A survey on the I-131 therapy of Graves' hyperthyroidism was undertaken by questionnaire in 1,246 hospitals of Japan. One thousand and ninety seven of them (88.0%) responded to the questionnaire. In this paper, we report the results and analysis of the replies to the questionnaire. In the 121 hospitals (11.03%) of the respondents, I-131 therapy is being performed for Graves' hyperthyroidism. A gradual increase was observed in the annual number of I-131 treated Graves' disease patients during the period of 1998-2001, from 1,740 to 2,484. I-131 treatment was selected mainly for the cases with side effects from antithyroid drug (ATD) therapy, followed by the cases with complication of heart or hepatic diseases, recurrences of hyperthyroidism after surgery, radioiodine treatment, and long-term ATD treatment. The 41% of respondents used I-131 in order to restore euthyroidism, 34% aimed for hyperthyroidism and 41% used the dose properly between the two according to the patients. Administration dosage of I-131 was estimated mainly on the basis of thyroid uptake and volume in 93% of the respondents and 48% calculated the radiation dose by also determining the effective half-life in the thyroid gland. Thyroid size was estimated by scintigram (51%), ultrasonography (US) (33%), CT (22%) and palpation (12%). ATD treatment was used before I-131 administration by 70% of the respondents and 34% after radioiodine therapy. A low-iodine diet was given to the patients for a week (46%) or two weeks (47%) before I-131 administration. However, after treatment only 46% of the respondents continued low-iodine diet for a week.

    The coexistence of diabetes mellitus and hyperthyroidism has long been known and, in a few cases, diabetic acidosis complicated with thyroid storm has been reported. We describe a case who developed thyroid storm and diabetic ketoacidosis following /sup 131/I therapy for severe hyperthyroidism. A 50-yr-old man was diagnosed as having hyperthyroidism complicated with diabetes mellitus at the age of 47. After he had been unsuccessfully treated with methimazole and oral hypoglycemic agents, radioactive iodine was administered twice. However, no remarkable effect was observed. After a third treatment with /sup 131/I, the patient showed symptoms like thyroid storm and diabetic ketoacidosis. He was hospitalized on October 3, 1980. Adm of insulin and supportive therapy including correction of dehydration alleviated his symptoms after admission. Administration of methimazole normalized his thyroid function. A 75 g GTT and tolbutamide i.v. test revealed impaired secretion of endogenous insulin. The patient had a high level of serum T/sub 3/ and T/sub 4/ following /sup 131/I therapy, indicating that the released hormone caused a transient condition like thyroid storm, which led to deterioration of glucose metabolism as indicated in high levels of hemoglobin A1c. Diabetic acidosis is the precipitating factor for thyroid storm. Prompt treatment for diabetic ketoacidosis, therefore, might prevent the complications of life-threatening thyroid storm.

    Radioactive iodine ( 131 I) was used in the treatment of a 12-year-old female dog with hyperthyroidism resulting from a large, unresectable (and metastatic) thyroid carcinoma associated with signs of severe inspiratory stridor and dyspnea. Hyperthyroidism was diagnosed on the basis of clinical signs (polyuria, polydipsia, polyphagia, weight loss, nervousness) and high basal serum thyroxine (T4) concentrations, as well as thyroid radioiodine kinetic studies that showed a high radioiodine uptake into the thyroid (% thyroid uptake) and markedly increased serum concentrations of protein-bound iodine-131 (PB 131 I) after 131 I tracer injection. Thyroid imaging revealed diffuse radionuclide accumulation by the tumor, which involved both thyroid lobes. The dog was treated with three large doses of radioiodine ( 131 I), ranging from 60 to 75 mCi, given at intervals of 5 to 7 months. The dog became euthyroid, and the size of the tumor decreased by approximately 25% after each 131 I treatment, improving the severe inspiratory stridor and dyspnea, but both the hyperthyroid state and breathing difficulty recurred within a few months of each treatment. The dog was euthanatized 5 months after the last treatment because of progressive tracheal compression and pulmonary metastasis

    Full Text Available Background: TSH receptor antibody (TRAb is considered the gold standard diagnostic test for the autoimmunity of Graves’ disease (GD, which is commonly diagnosed clinically. Aim: To evaluate the true positive (sensitivity and true negative (specificity rates of clinical diagnosis of GD or non-GD hyperthyroidism compared to the TRAb test. Setting: University teaching hospital in North West England. Participants: Patients in the Endocrinology service who had a TRAb measurement between December 2009 and October 2015. Methods: Electronic patient records were studied retrospectively for a pre-TRAb clinical diagnosis of GD or non-GD hyperthyroidism. We examined descriptive statistics and binary classification tests; Fisher exact test was used to analyse contingency tables. Results: We identified 316 patients with a mean age of 45 (range, 17–89 years; 247 (78% were women. Compared to the TRAb result, clinical diagnosis had a sensitivity of 88%, specificity 66%, positive predictive value 72%, negative predictive value 84%, false negative rate 12%, false positive rate 34%, positive likelihood ratio 2.6 and negative likelihood ratio 0.2 (P < 0.0001. Conclusions: Clinicians were liable to both over- and under-diagnose GD. The TRAb test can help reduce the number of incorrect or unknown diagnoses in the initial clinical assessment of patients presenting with hyperthyroidism.

    We describe here five cardiac patients with type II amiodarone-induced hyperthyroidism who were treated prospectively with a combination of an oral cholecystographic agent (sodium ipodate, Oragrafin, or sodium iopanoate, Telepaque) and a thionamide (propylthiouracil or methimazole); amiodarone was discontinued in all patients. All patients improved substantially clinically within a few days of treatment and became euthyroid or hypothyroid in 15-31 wk when treatment was discontinued. Four of the five became hypothyroid and required long-term treatment with L-T(4); the remaining patient was euthyroid, but died from cardiomyopathy and congestive heart failure at 29 wk, when he had been off oral cholecystographic agent and thionamide for 6 wk. We did not find any clinical or biochemical adverse effects of the treatment. Our study suggests that a combination of oral cholecystographic agent and thionamide is a safe and effective treatment of type II amiodarone-induced hyperthyroidism. Data also suggest that hypothyroidism is a common end result of type II amiodarone-induced hyperthyroidism.

    Acute hepatic failure is a rare and potentially lethal complication of propylthiouracil (PTU) use for hyperthyroidism. We present a 20-year-old woman with Basedow-Graves' disease who developed PTU-induced fulminant hepatitis, which progressed to acute hepatic failure with grade III hepatic encephalopathy. Laboratory evaluation ruled out the most common causes of fulminant hepatitis. We treated her hyperthyroidism with amiodarone (average daily dose, 200 mg) for 3 weeks, achieving rapid and persistent euthyroidism, (triiodothyronine [T(3)] levels ranged between 64 and 109 ng/dL) without side effects. Amiodarone treatment did not abolish the thyroid radioactive iodine uptake (RAIU), allowing for subsequent treatment with radioactive iodine. The clinical course was favorable and the patient achieved full hepatic recovery 3 months after the hepatic failure was detected. After an extensive review of the literature, we believe that this is the first communication of the successful use of amiodarone to control hyperthyroidism in a patient with PTU-induced fulminant hepatitis.

    To exploit the antiarrhythmic effect of amiodarone when patients develop the side effect of thyrotoxicosis three patients with hyperthyroidism induced by amiodarone were given simultaneously 1 g potassium perchlorate a day for 40 days and a starting dose of 40 mg methimazole a day while they continued to take amiodarone. As hyperthyroidism might have recurred after potassium perchlorate treatment was stopped the dose of methimazole was not reduced until biochemical hypothyroidism (raised thyroid stimulating hormone concentrations) was achieved. The patients became euthyroid (free triiodothyronine concentration returned to normal values) in two to five weeks and hypothyroid in 10 to 14 weeks. One patient became euthyroid while taking 5 mg methimazole a day and 600 mg amiodarone weekly; the two others required substitution treatment with thyroxine sodium while taking 5 mg methimazole or 50 mg propylthiouracil (because of an allergic reaction to methimazole) and 2100 or 1400 mg amiodarone weekly. Hyperthyroidism induced by amiodarone may be treated with potassium perchlorate and methimazole given simultaneously while treatment with amiodarone is continued. PMID:2547467

    The coexistence of diabetes mellitus and hyperthyroidism has long been known and, in a few cases, diabetic acidosis complicated with thyroid storm has been reported. We describe a case who developed thyroid storm and diabetic ketoacidosis following 131 I therapy for severe hyperthyroidism. A 50-yr-old man was diagnosed as having hyperthyroidism complicated with diabetes mellitus at the age of 47. After he had been unsuccessfully treated with methimazole and oral hypoglycemic agents, radioactive iodine was administered twice. However, no remarkable effect was observed. After a third treatment with 131 I, the patient showed symptoms like thyroid storm and diabetic ketoacidosis. He was hospitalized on October 3, 1980. Administration of insulin and supportive therapy including correction of dehydration alleviated his symptoms after admission. Administration inistration of methimazole normalized his thyroid function. A 75 g GTT and tolbutamide i.v. test revealed impaired secretion of endogenous insulin. The patient had a high level of serum T 3 and T 4 following 131 I therapy, indicating that the released hormone caused a transient condition like thyroid storm, which led to deterioration of glucose metabolism as indicated in high levels of hemoglobin A1c. Diabetic acidosis is the precipitating factor for thyroid storm. Prompt treatment for diabetic ketoacidosis, therefore, might prevent the complications of life-threatening thyroid storm. (author)

    Full Text Available Metabolic dysfunctions might play a crucial role in the pathophysiology of thyroid dysfunctions. This study aimed to investigate the impact of a controlled diet (normal versus high fat feeding on hypothyroid and hyperthyroid Sprague Dawley rats. Female Sprague Dawley rats (n = 66 were grouped into normal diet (n = 30 and high-fat diet (n = 36 groups and subdivided into controls, hypothyroid and hyperthyroid groups, induced through propylthiouracil or triiodothyronine (T3 treatment, respectively. After 12 weeks of treatment metabolic parameters, such as oxidized LDL (oxLDL, malondialdehyde (MDA, 4-hydroxynonenal (HNE, the lipid profile, body weight and food intake parameters were analyzed. Successfully induced thyroid dysfunctions were shown by T3 levels, both under normal and high fat diet. Thyroid dysfunctions were accompanied by changes in calorie intake and body weight as well as in the lipid profile. In detail, hypothyroid rats showed significantly decreased oxLDL levels, whereas hyperthyroid rats showed significantly increased oxLDL levels. These effects were seen under high fat diet and were less pronounced with normal feeding. Taken together, we showed for the first time in female SD rats that only hyper-, but not hypothyroidism, is associated with high atherogenic oxidized LDL irrespective of normal or high-fat diet in Sprague Dawley rats.

    This report deals with materials and structures of temporary air-raid shelters. At first, the weapon effects against which the temporary shelters can protect are described. These are, primarily, the fragmentation and blast pressure caused by conventional weapons and those effects of the nuclear weapons which exist outside the total disaster and fire areas. Temporary shelters built into existing buildings can give protection either from radioactive fallout or from fallout and collapse of the building above. For fallout protection heavy materials are needed, which simultaneously protect from fragmentation. In the research report, the methods and materials used for the contruction of a fallout shelter into an apartment house and a small house are introduced. The collapse loads acting on a basement ceiling and the design of additional timber supports are also presented. The use of various materials in the construction of shelters outside the buildings are introduced. Separate shelters can be built either under the ground or on the ground. The same materials can be used in both cases, but the underground shelters have a better level of protection. (author)

    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

    Objective: To evaluate the clinical research and long-term follow-up results of early hypothyroidism after 131 I treatment for hyperthyroidism. Methods: One hundred and forty-five patients with hyperthyroidism who developed hypothyroidism within 12 months after 131 I therapy were evaluated by clinical symptoms and plasma T 3 , T 4 , thyroid-stimulating hormone (TSH). One year after treatment, 121 of 145 patients were divided into two groups according to the occurrence of hypothyroidism. Results: 1) Group 1: transient hypothyroidism (n=33), 64%(21/33) of the patients developed euthyroidism and 36%(12/33) patients had recurrent hyperthyroidism within 1 year after being diagnosed with hypothyroidism after 131 I treatment. The long-term follow-up showed 2 patients were with euthyroidism and 2 patients who were previously with hyperthyroidism developed permanent hypothyroidism after 3 months ∼6 years. Three patients who were previously with hyperthyroidism developed euthyroidism after 3 months ∼5 years. Group 2: permanent hypothyroidism (n=88), 82.95% (73/88) patients of group 2 were treated with low-dose 131 I, 86.36% (76/88) cases of this group were found with clinical hypothyroidism. Conclusions: 72.73% (88/121) patients of early hypothyroidism after 131 I therapy developed permanent hypothyroidism. The incidence of permanent hypothyroidism in the patients treated with low-dose 131 I was higher. Recovery of transient hypothyroidism after 131 I therapy did not predict future thyroid function.

  3. Diagnosis of pediatric hyperthyroidism: technetium 99 uptake versus thyroid stimulating immunoglobulins.

    Treatment with antithyroid drugs is effective in conditions of increased thyroid hormone production (mostly Graves' Disease; GD), but not in subacute thyroiditis (SAT) or autoimmune thyroiditis (AIT). Positive thyroid stimulating immunoglobulins (TSI) make GD likely. However, not all children with GD have increased TSI. Uptake studies with (123)I or (99)Tc ((99m)Tc) provide accurate and rapid diagnosis but are expensive and involve radiation exposure. Our objective was to compare TSI with (99m)Tc uptake for diagnosis of pediatric hyperthyroidism. We performed a retrospective chart review of hyperthyroid children who had both TSI estimation and (99m)Tc uptake assessment at presentation. Based on subsequent laboratory studies and follow-up, 37 had GD and 10 had non-GD thyroiditis. The TSI index was considered positive (TSI+) when it was above the upper limit of normal. (99m)Tc uptake was considered positive (Tc+) for any uptake >0.4% and negative (and low) (Tc-) for uptake ≤0.4%. Forty-seven youth (83% females), aged 12.3±4.6 years, presented with a suppressed thyrotropin (TSH) and elevated free thyroxine and total triiodothyronine. All 37 patients with GD were Tc+ (100% sensitivity and specificity). The sensitivity of TSI for diagnosing GD was 84%, and the specificity was 100%. Six patients with GD were discordant with Tc+ but TSI-. Elevated TSI correlated with Tc+ (p=0.01) with a degree of agreement (kappa) of 0.69. (99m)Tc has excellent specificity and sensitivity in diagnosing GD. Given additional costs of (99m)Tc (two and a half times as much as TSI), it is reasonable to reserve (99m)Tc uptake assessment for hyperthyroidism of unclear etiology and negative TSI.

  4. Relationship between thyroid stimulating hormone and thyroid stimulating immunoglobulin in Graves' hyperthyroidism.

    In Graves' hyperthyroidism, suppression of serum TSH after restoration of normal serum T4 and T3 with treatment has been attributed to binding of TSH-receptor antibodies to TSH receptors in the pituitary. Accordingly, the relationship between TSH and serum thyroid stimulating immunoglobulin (TSI) was examined during follow-up of patients with Graves' hyperthyroidism. 23 patients with Graves' hyperthyroidism were identified who met the inclusion criteria of at least 24 months follow-up after initiation of methimazole and availability of concurrent measurements of serum TSH and TSI. TSI disappeared in 12 patients (Group A) and persisted in 11 patients (Group B). Initial T4 was not significantly different between the 2 groups. However, TSI was significantly lower in Group A than Group B [median (interquartile range) 179 (152-212)% vs 255 (208-369)%, p=0.0009]. In Group A, TSH normalized during treatment, and this anteceded disappearance of TSI by a significant time interval [median (interquartile range) 6 (3-8) months vs 15 (11-20) months, p=0.005]. In Group B, TSI persisted in all patients during follow-up ranging from 24 to 73 months. No correlation was found to exist between serum TSH and TSI, and for Group B TSI at final follow-up was not significantly different from the initial value [median (interquartile range) 255 (208-369)% vs 236 (160-310)%, p=0.4]. These findings do not support the suggestion that TSI has a direct suppressive effect on TSH secretion.

    Full Text Available Diabetes mellitus is a common endocrinopathy of cats that is characterized by persistent fasting hyperglycemia. However, stress induces substantial hyperglycemia in cats that poses a challenge to the veterinarian who may wrongly interpret the high serum concentration of blood glucose as evidence of diabetes mellitus. Fructosamine is a glycated serum protein that serves as an index of glycemic control in cats and is useful because it is not affected by stress hyperglycemia. However, factors such as body weight, hypoproteinemia, and increased serum thyroid hormone concentration can alter fructosamine concentration. The goal of this retrospective study was to compare the fructosamine concentrations in diabetic and nondiabetic cats with and without uncontrolled hyperthyroidism. A secondary goal was to determine the effect of sex, age, different populations of cats, and diabetes on the variability of fructosamine. We found that the mean (±SE serum fructosamine of hyperthyroid diabetic cats (332 ± 24 µmol/L, 95% CI 291–379 µmol/L was within the population-based reference interval (200–360 µmol/L and significantly lower in comparison to euthyroid diabetic cats (527 ± 10 µmol/L, 95% CI 515–553 µmol/L. Additionally, in this study, diabetes accounted only for approximately 50% of the variance in serum fructosamine, while age, sex, and population made a minor contribution to this variance. In conclusion, finding serum fructosamine that is within the population-based reference interval in an uncontrolled diabetic cat should alert the veterinarian to the possibility of concurrent hyperthyroidism. Additionally, the veterinary clinician should consider that serum fructosamine might be substantially affected by factors other than diabetes.

    The aim of this study was to determine whether hydrochlorothiazide (HCTZ) could improve radioiodine uptake in low-uptake hyperthyroid patients. Eighteen hyperthyroid patients with low 3-h and 24-h iodine-131 uptake were recruited to the study. Eleven patients were assigned to the HCTZ group, and seven to the control group. Two weeks after the first, baseline uptake study, a second uptake study was performed. Patients in both groups had a low-iodine diet after the first uptake study. In the HCTZ group, 50 mg of HCTZ was administered twice a day for 5 days prior to the second uptake study. Improvement in uptake at 3 and 24 h in the second uptake study, as compared with the baseline study, was assessed within and between groups. In the control group, compared with the baseline study there was a significant improvement in uptake at 3 h (P=0.03) but a non-significant improvement at 24 h (P=0.07). In the HCTZ group, significant improvements were observed at both 3 h (P=0.0005) and 24 h (P=2.28 x 10{sup -5}). Patients in the HCTZ group had statistically greater improvement in uptake at both 3 h and 24 h compared with the control group (P=0.003 and 0.0008, respectively). There was a 7.18-fold average improvement in uptake in the HCTZ group at 24 h, compared with only a 1.33-fold improvement in the control group. Administration of HCTZ significantly improves 24-h radioiodine uptake in high-iodide pool, low-uptake hyperthyroid patients compared with patients who have received a low-iodine diet alone. (orig.)

    To investigate the effect of preoperative Lugol's iodine on intraoperative bleeding in patients with hyperthyroidism. This controlled, randomized, prospective cohort was carried out on 40 patients who admitted for surgery due to hyperthyroidism. Cases were randomly assigned to receive either preoperative treatment with Lugol solution (Group 1) or no preoperative treatment with Lugol solution (Group 2). Group 3 (n = 10) consisted of healthy adults with no known history and signs of hyperthyroidism. Blood flow through the thyroid arteries of patients was measured by color flow Doppler ultrasonography. Free T3, free T4, TSH, thyroid volume and the resistance index of the four main thyroid arteries were measured in all patients. There was not a significant difference between gender, preoperative serum thyroid hormone levels, or thyroid gland volumes between groups 1 and 2. The mean blood flow of the patients in Group 1 was significantly lower than values in Group 2. When age, gender, thyroid hormone, TSH, thyroid volume, blood flow, and Lugol solution treatment were included as independent variables, Lugol solution treatment (OR, 7.40; 95% CI, 1.02-58.46; p = 0.001) was found to be the only significant independent determinant of intraoperative blood loss. Lugol solution treatment resulted in a 7.40-fold decrease in the rate of intraoperative blood loss. Preoperative Lugol solution treatment was found to be a significant independent determinant of intraoperative blood loss. Moreover, preoperative Lugol solution treatment decreased the rate of blood flow, and intraoperative blood loss during thyroidectomy.

    Patients with obstructive hypertrophic cardiomyopathy who undergo septal myectomy are at risk for developing postoperative atrial fibrillation. Amiodarone is effective in treating this arrhythmia but is associated with multiple adverse effects, often with delayed onset. A novel case is described of a patient who developed type 2 amiodarone-induced hyperthyroidism that presented as recurrence of outflow obstruction after septal myectomy. The patient's symptoms and echocardiographic findings of outflow obstruction resolved substantially with the treatment of the amiodarone-induced hyperthyroidism. Amiodarone-induced hyperthyroidism of delayed onset can be a subtle diagnosis, requiring a high index of suspicion. In conclusion, recognition of this diagnosis in patients with recurrence of outflow obstruction by symptoms and cardiac imaging after septal myectomy may avoid unnecessary repeat surgical intervention.

    We have studied the long-term incidence of hypothyroidism in 4,473 formerly hyperthyroid patients given I-131 therapy between 1951 and 1975. The mean age at the first I-131 treatment was 56 yr. Six percent developed hypothyroidism within one year of therapy, and 72% within 26 yr. Prior antithyroid medication did not affect the incidence of hypothyroidism. Patients cured with one dose of I-131 had a lower cumulative long-term incidence of hypothyroidism than those requiring more than one dose

    Factors related to late hypothyroidism following the use of /sup 131/I for treatment of hyperthyroidism are discussed with regard to age of patient, size of dose, previous surgery, immune status, and others. Possible reasons for the post-therapeutic hypothyroidism are discussed with regard to effects of radiation on the reproductive capacity of thyroid cells, effects of radiation on blood vessels, and dose distribution of radioiodine. The following therapeutic strategies are discussed: reduction of initial dose; multiple small doses; high dose radioiodine followed by replacement therapy; the use of external beam irradiation; and the use of /sup 125/I.

    Objective: The hippocampus expresses high levels of thyroid hormone receptors, suggesting that hippocampal functions, including cognition and regulation of mood, can be disrupted by thyroid pathology. Indeed, structural and functional alterations within the hippocampus have been observed in hyperthyroid patients. In addition to internal circuitry, hippocampal processing is dependent on extensive connections with other limbic and neocortical structures, but the effects of hyperthyroidism on functional connectivity (FC) with these areas have not been studied. The purpose of this study was to investigate possible abnormalities in the FC between the hippocampus and other neural structures in hyperthyroid patients using resting-state fMRI. Methods: Seed-based correlation analysis was performed on resting-state fMRI data to reveal possible differences in hippocampal FC between hyperthyroid patients and healthy controls. Correlation analysis was used to investigate the relationships between the strength of FC in regions showing significant group differences and clinical variables. Results: Compared to controls, hyperthyroid patients showed weaker FC between the bilateral hippocampus and both the bilateral anterior cingulate cortex (ACC) and bilateral posterior cingulate cortex (PCC), as well as between the right hippocampus and right medial orbitofrontal cortex (mOFC). Disease duration was negatively correlated with FC strength between the bilateral hippocampus and bilateral ACC and PCC. Levels of depression and anxiety were negatively correlated with FC strength between the bilateral hippocampus and bilateral ACC. Conclusion: Decreased functional connectivity between the hippocampus and bilateral ACC, PCC, and right mOFC may contribute to the emotional and cognitive dysfunction associated with hyperthyroidism

    Objective: The hippocampus expresses high levels of thyroid hormone receptors, suggesting that hippocampal functions, including cognition and regulation of mood, can be disrupted by thyroid pathology. Indeed, structural and functional alterations within the hippocampus have been observed in hyperthyroid patients. In addition to internal circuitry, hippocampal processing is dependent on extensive connections with other limbic and neocortical structures, but the effects of hyperthyroidism on functional connectivity (FC) with these areas have not been studied. The purpose of this study was to investigate possible abnormalities in the FC between the hippocampus and other neural structures in hyperthyroid patients using resting-state fMRI. Methods: Seed-based correlation analysis was performed on resting-state fMRI data to reveal possible differences in hippocampal FC between hyperthyroid patients and healthy controls. Correlation analysis was used to investigate the relationships between the strength of FC in regions showing significant group differences and clinical variables. Results: Compared to controls, hyperthyroid patients showed weaker FC between the bilateral hippocampus and both the bilateral anterior cingulate cortex (ACC) and bilateral posterior cingulate cortex (PCC), as well as between the right hippocampus and right medial orbitofrontal cortex (mOFC). Disease duration was negatively correlated with FC strength between the bilateral hippocampus and bilateral ACC and PCC. Levels of depression and anxiety were negatively correlated with FC strength between the bilateral hippocampus and bilateral ACC. Conclusion: Decreased functional connectivity between the hippocampus and bilateral ACC, PCC, and right mOFC may contribute to the emotional and cognitive dysfunction associated with hyperthyroidism.

    To study the effect of a iodine load on thyroid function of patients with ischaemic heart disease (IHD) and the long-term influence of unknown subclinical hyperthyroidism. Subclinical hyperthyroidism is considered an independent risk factors for cardiovascular morbidity of patients with IHD. They routinely undergo coronary angiography with iodine contrast media (ICM) which may induce or even worsen hyperthyroidism. A cross-sectional study followed by a longitudinal study on patients with subclinical hyperthyroidism. 810 consecutive IHD outpatients without known thyroid diseases or treatment with drugs influencing thyroid activity undergoing elective coronary angiography. We evaluated thyroid function either before and 1 month after ICM; patients with thyrotoxicosis at baseline or after ICM were then followed up for 1 year. 58 patients had hyperthyroidism at baseline (HB, 7.2%), independently associated to FT4 levels, thyroid nodules and family history of thyroid diseases. After ICM, the prevalence of hyperthyroidism was 81 (10%). Hyperthyroidism after ICM was positively predicted by baseline fT4 levels, thyroid nodules, age over 60, male gender, family history of thyroid diseases. Three months after ICM, 34 patients (4.2%) still showed hyperthyroidism (22 from HB, 13 treated with methimazole). One year after ICM, hyperthyroidism was still present in 20 patients (2.5%, all from HB, 13 treated). The prevalence of spontaneous subclinical hyperthyroidism in IHD is surprisingly elevated and is further increased by iodine load, particularly in patients with thyroid nodules and familial history of thyroid diseases, persisting in a not negligible number of them even after one year. © 2017 John Wiley & Sons Ltd.

    Thirty-one cats with hyperthyroidism were given one dose of radioactive iodine (131I) IV. Serum thyroxine (T4) concentrations were measured before treatment in all cats, at 12-hour intervals after treatment in 10 cats, and at 48-hour intervals after treatment in 21 cats. Serum T4 concentrations also were measured one month after 131 I therapy in 29 cats. Activity of 131I administered was 1.5 to 6.13 mCi, resulting in a dose of 20,000 rads to the thyroid. Serum T4 concentrations before 131 I administration were 5.3 to 51.0 micrograms/dl, with a median T4 concentration of 11.0 micrograms/dl. Serum T4 decreased most rapidly during the first 3 to 6 days after treatment. Sixteen cats (55%) had normal serum thyroxine concentrations by day 4 after 131I administration, and 23 cats (74%) were euthyroxinemic by day 8 after treatment. One month after administration of 131I, the 29 cats evaluated were clinically improved, and 24 (83%) of the 29 cats evaluated had normal serum T4 concentrations, 3 cats (10%) remained hyperthyroxinemic, and 2 cats (7%) were hypothyroxinemic. Therefore, administration of 131I was a safe and effective method to quickly decrease serum T4 concentrations in hyperthyroid cats

  19. A mathematical model of optimized radioiodine-131 therapy of Graves' hyperthyroidism

    The current status of radioiodine-131 (RaI) dosimetry for Graves' hyperthyroidism is not clear. Recurrent hyperthyroidism and iatrogenic hypothyroidism are two problems which interact such that trying to solve one leads to exacerbation of the other. Optimized RaI therapy has therefore begun to be defined just in terms of early hypothyroidism (ablative therapy) as physicians have given up on reducing hypothyroidism. Optimized therapy is evaluated both in terms of the greatest separation of cure rate from hypothyroidism rate (non-ablative therapy) or in terms of early hypothyroidism (ablative therapy) by mathematical modeling of outcome after radioiodine and critically discussing the three common methods of RaI dosing for Graves' disease. Cure follows a logarithmic relationship to activity administered or absorbed dose, while hypothyroidism follows a linear relationship. The effect of including or omitting factors in the calculation of the administered I–131 activity such as the measured thyroid uptake and effective half-life of RaI or giving extra compensation for gland size is discussed. Very little benefit can be gained by employing complicated methods of RaI dose selection for non-ablative therapy since the standard activity model shows the best potential for cure and prolonged euthyroidism. For ablative therapy, a standard MBq/g dosing provides the best outcome in terms of cure and early hypothyroidism

  20. Iodine-induced hyperthyroidism as combination of different etiologies: an overlooked entity in the elderly.

    Iodine-induced thyrotoxicosis, which raises several diagnostic and therapeutical challenges, is often overlooked. Hyperthyroidism can induce atrial fibrillation, a harmful arrhythmia which can precipitate heart failure and cause stroke. We report the case of an elderly man who was diagnosed with tachyfibrillation secondary to hyperthyroidism. Thyroid hyperfunction was subsequently related both to previous amiodarone therapy (probably mixed form) and the recent use of iodinated contrast medium for computed tomography scan. Thyroid ultrasonography showed a plongeant multinodular goitre. After initial worsening, thyroid function improved slowly but progressively on high-dose thyreostatic therapy combined with steroid therapy; tachyfibrillation caused heart failure and a thrombus in the left atrium, and proved initially resistant to combined antiarrhythmic treatments. Progressive reduction in thyroid hormone levels, together with combined cardiologic therapies, controlled the heart rate, though atrial fibrillation persisted; anticoagulant therapy resolved the atrial thrombus. Alterations in thyroid function are common in amiodarone-treated patients, who therefore require regular hormonal checks. The different forms of amiodarone-induced thyrotoxicosis must be investigated, since they require different therapies, though mixed forms often occur. The superimposition of further iodine excess due to other causes may be catastrophic and cause severe cardiac problems in these patients.

    Objective: To explore the interrelationship among the three thyroid antibodies and their role in clinical diagnosis of thyroid auto-immune diseases by combined determination of serum TGA, TMA and TRAb in 84 patients with Hyperthyroidism. Methods; Based upon the serum concentrations of TGA and TMA, the 84 patients were divided into three groups; TGA, TMA negative group (TGA, TMA 6.84 u/L) in 60 of the 84 patients with hyperthyroidism (71.5%). For the separate groups, TRAb concentrations were positive in 42.9% of the patients of the TGA, TMA negative group, 75.0% of the TGA, TMA positive group and 85.7% of the strongly positive group. TRAb concentrations were significantly higher in patients of the strongly positive group than those in patients of the positive and negative group, but were not much different between patients of the positive and negative group. Conclusion: Positive rate of the serum TRAb increased along with the increase of positive rate of TGA and TMA. In this series of 84 thyrotoxic patients, TGA and TMA concentrations were strongly positive in 41.7% of them. It was possible that some of those strongly positive patients were of the Hashimoto type instead of Graves type

    Hyperthyroidism is associated with negative calcium balance, normal to increased serum calcium concentrations, and decreased cortical bone mass. There is no agreement concerning serum PTH levels in such patients. In this study, we measured serum PTH concentrations using a newly developed sensitive 2-site immunoradiometric assay in 17 hyperthyroid patients before and after radioiodine therapy. The mean serum PTH and calcium concentrations were 28 +/- 15 (+/- SD) ng/L (normal range, 12-65 ng/L) and 2.4 +/- 0.5 mmol/L (normal range, 2.1-2.6 mmol/L) before therapy. After therapy serum PTH concentrations increased in 16 of the 17 patients. The increase in serum PTH was greater in the 9 patients who became hypothyroid rapidly (29 +/- 15 to 75 +/- 29 ng/L) compared with that in the 8 patients who became euthyroid gradually (26 +/- 16 to 45 +/- 24 ng/L). Serum PTH rose along with TSH as the patients became hypothyroid after radioiodine, and both serum PTH and TSH fell when L-T4 therapy was given. The reciprocal changes in serum PTH concentrations and thyroid function over time suggest a strong association of bone mineral metabolism and thyroid status

    To investigate the therapeutic effect through long-term visit and analyze the affecting factors of cure rate after iodine-131 therapy for hyperthyroidism, a long-term follow-up has been undertaken for the patients with hyperthyroidism after iodine-131 treatment. The following results have been obtained. (1) The cure rate of iodine-131 therapy for hyperthyroidism is 74.4%, and the incidence of permanent hypothyroidism is 7.5%. (2) There is no significant difference in the cure rate and incidence of hypothyroidism between the groups of male and female or 'not take ATD' and 'ATD withdrawn longer than 2 weeks' (P>0.05). (3) The difference of the cure rate among the groups of the courses of disease 3 a are significant (P 55 g are significant (P 0.05). The course of disease, age and thyroid mass are the major factors which influence the cure rate. Meanwhile, age and thyroid mass are the major factors which influence the incidence of hypothyroidism. To get high cure rate, the patients with hyperthyroidism should be treated with iodine-131 as early as possible. In the meantime, the incidence of permanent hypothyroidism must be paid attention to.

    Thyroid storm is extremely rare. However, hyperthyroid patients with severe thyrotoxicosis are frequently not treated immediately with I-131 for fear of thyroid storm but are placed on thiouracil drugs for varying periods of time. We demonstrate herein that it is safe to treat these patients with I-131, without pretreatment with thiouracil drugs, provided they do not have complicating intercurrent disease. Our definition of severe hyperthyroidism includes marked signs and symptoms of thyrotoxicosis, suppressed thyroid stimulating hormone (TSH), markedly elevated free T4 and/or free T3 and elevated radioactive iodine uptake (RAIU) (>30%) at 4 or 24 hours. Our diagnostic criteria for thyroid storm include two or more findings of fever (>38 deg C, 100 deg F), severe tachycardia, high pulse pressure, agitation with tremors, flushing, sweating, heart failure, nausea, vomiting, diarrhea, jaundice associated with high free T4 and/or free T3. Patients were selected retrospectively for the period between August 2003 and December 2004. One hundred and twenty-two patient visits were identified. These patients were treated with 370-740 MBq (10-20 mCi) of I-131 and were evaluated for any evidence of thyroid storm. Most of the patients were placed on beta blocker drugs at the time of initial I-131 therapy; these were continued for at least two months, when the first follow-up visit occurred. At the time of I-131 therapy, it is our policy to educate the patients to seek immediate medical attention for exacerbation of symptoms of thyrotoxicosis. Not one of these patients developed thyroid storm. A subset of 25% of these cases with higher potential for thyroid storm (RAIU more than 65%, very marked signs and symptoms, and very markedly elevated free T4 and/or free T3) also tolerated the I-131 therapy well with marked clinical improvement and no exacerbation of the thyrotoxic state. It is safe to administer I-131 to patients who are severely hyperthyroid without fear of thyroid

    The authors have summarized their works of more than 20 years using I-131 for treatment and close observation of 723 patients with hyperthyroidism in 1000 ones in the Nuclear Medicine Department, Bach Mai University Hospital in Hanoi to collect data and draw experience for the report. Patient selection for the treatment is based on clinical features and laboratory tests results by the Nuclear Medicine Department such as thyroid uptake, scintigraphy and RIA determinations of thyroid hormones. I-131 dose is determined in compliance with a prevailing formula. The average dose is 6.2 ± 1.1 mCi (that is 233.1 ± 40.7 MBq). The average number of times is 1.3 time for one patient. The results are as follows: Euthyroid status after 4- year following- up from date of I-131 dose administration: 72.3%; Persistent or recurrent hyperthyroidism: 20.0%; Hypothyroid complications: appear 4 to 12 months after date of I-131 administration: 3.0%; appear 4 years after date of I-131 administration: 7.7%; appear 6 years after date of I-131 administration. 14.0%; so the cumulative hypothyroid rate is 2.3% per year. No occurrence of other serious complications by all the observed patients. This is therefore a safe, efficient treatment method to be applied on a large scale including adolescents and children. However, much more study has still to be made on the dose due to high rate of recurrence of the therapeutic method although the hypothyroid complications cases are not serious. Hyperthyroidism is a common health problem in Viet Nam. Previously, only anti-thyroid drugs and surgery were used. Use of I-131 was firstly introduced to Viet Nam in the Nuclear Medicine Department in Bach Mai in 1974 and afterwards applied larger nationwide. Initial therapeutic results have been published in national medical magazines. This is a general study aiming at analyzing the way to carry out the work and get experience and recommendation from gained results for further work in the future. (author)

    The study was carried out on 21 female hyperthyroid patients aged 22-53 years, with or without associated ophthalmopathy, admitted to the Endocrinology ward of the 1st Medical Clinic of the Craiova County Hospital, Romania, between 1983 and 1985. Administration of lithium carbonate was proceeded and followed by radioimmunoassay (RIA) determinations of T3 and T4 and measurement of Achilles' reflex (AR). Two regimens were employed. The first comprised ten patients receiving doses of 500 mg/day lithium carbonate and the second 11 patients who had an associated ophthalmopathy and who received 250 mg/day lithium carbonate and 30 mg/day carbimazole. Lithium administration was discontinued after 4 weeks. The results of the therapy suggest a possible intervention of lithium carbonate in the process of blocking the biosynthesis of thyroid hormones and/or its regulating processes, with concomitant improvement of the clinical status, much more in the patients without ophthalmopathy.

    Of 963 physicians surveyed to determine therapeutic attitudes toward, and experience with inadvertent radioiodine therapy for hyperthyroidism during the first trimester of pregnancy, 116 physicians (of 517 responding) reported 237 cases. Therapeutic abortion was advised for 55 patients by 22 physicans. From the 182 remaining pregnancies there were two spontaneous abortions, two stillborn, one neonate with biliary atresia, and one with respiratory distress. This complication rate was not greater than might be expected in a similar number of random pregnancies. On the other hand, six infants were hypothyroid (transient for one) and four of these were mentally deficient. Three mothers of hypothyroid infants had received radioiodine therapy in the second trimester. None of the six mothers of hypothyroid infants had had pregnancy tests prior to radioiodine therapy. Survey responses indicate that routine pregnancy testing prior to radioiodine therapy for patients in the child-bearing age is not yet a standard procedure. It should be

    The incidence of hypothyroidism was analyzed in 4,553 hyperthyroid patients treated with I-131 between 1951 and 1975. The average annual rate of hypothyroidism during the first 7 yr after therapy increased continuously for each 5-yr period of treatment, from 3.6% for patients treated between 1951 and 1955 to 7.7% for patients treated during the period from 1971 through 1975 (p<0.001). The increase in the incidence of hypothyroidism was seen before the introduction of TSH assays and when allowance was made for thyroid gland size, the age of the patient, and the experience of the radiotherapist. The use of TSH assays has probably resulted in an earlier recognition of hypothyroidism, which may explain why the most marked rise in the incidence of hypothyroidism was observed after the introduction of TSH assays

METHODS: This was a case-control study using record-linkage data from nationwide Danish health...... registers. 28,461 patients with GD and 17,283 with TNG were included. Each case was age and sex matched with four non-hyperthyroid controls and followed over a mean period of 8 years. Data on glaucoma was obtained by record linkage within the National Danish Patient Register and/or the Danish National...... Prescription Registry. Logistic and Cox regression models were used to assess the risk of glaucoma before and after the diagnosis of GD and TNG. RESULTS: Compared to controls, there was a significantly increased frequency of glaucoma in patients with GD (4.6 vs. 4.2%, P = 0.006) and in patients with TNG (6...

  18. Management of hypothyroidism after radioiodine treatment of hyperthyroidism and thyroid cancer

    Radioactive iodine (RAI) has been in use for over 40 years to treat hyperthyroidism and thyroid cancer. There is common knowledge that the aim in hyperthyroidism is to produce normal thyroid functions or render the patient euthyroid. It is the choice in properly selected patients as it is safe, convenient and there is rapid elimination of goiter and symptoms. In thyroid cancer, namely - papillary and follicular or well-differentiated ones, it ablates residual thyroid tissues not removed totally by surgery. This has, in all studies, improved life expectancy. The most important aspect in the use of I-131 for hyperthyroidism is to stress to the patient the need for constant follow-up and the recognition of the signs and symptoms of hypothyroidism which is inevitible. Recurrent hyperthyroidism and iatrogenic hypothyroidism are two problems which interact in such a way that trying to solve one leads to exacerbation of the other. Cure follows a logarithmic relationship to activity or absorbed dose, while the hypothyroidism follows a linear relationship. Even though we calculate point for point the administered dose (fixed or preferred dose) hypothyroidism still occurs. Dose calculation schemes have been discussed and it follows that the higher the dose is, the higher the percentage of cure is but the higher the chance is for eventual hypothyroidism. Diagnosis of hypothyroidism is based on clinical history that the patient received RAI for toxicosis, plus signs and symptoms of weight gain, hoarseness, sleepy, sluggish, muscle cramps, fatigue, poor memory and concentration, dry skin, constipation, depression, menstrual irregularities as menorrhagia or amenorrhea and infertility. Physical examination would reveal bradycardia, non-palpable thyroid gland, slow speech, cool dry skin and delayed relaxation of deep tendon reflexes. Biochemical parameters would show as elevated TSH, low T4 and low T3. Management of thyroid hormone replacement involves using levothyroxine sodium

    Some unhealthy life habits, such as long-term smoking, heavy drinking, sexual overstrain and frequent stay-up could induce the Yin deficiency symptoms of zygomatic red and dysphoria. Stems of Dendrobii officinalis flos (DOF) showed the efficacy of nourishing Yin. In this study, the hyperthyroidism Yin deficiency model was set up to study the yin nourishing effect and action mechanism of DOF, in order to provide the pharmacological basis for developing DOF resources and decreasing resource wastes. ICR mice were divided into five groups: the normal control group, the model control group, the positive control group and DOF extract groups (6.4 g · kg(-1)). Except for the normal group, the other groups were administrated with thyroxine for 30 d to set up the hyperthyroidism yin deficiency model. At the same time, the other groups were administrated with the corresponding drugs for 30 d. After administration for 4 weeks, the signs (facial temperature, pain domain, heart rate and autonomic activity) in mice were measured, and the facial and ear micro-circulation blood flow were detected by laser Doppler technology. After the last administration, all mice were fasted for 12 hours, blood were collected from their orbits, and serum were separated to detect AST, ALT, TG and TP by the automatic biochemistry analyzer and test T3, T4 and TSH levels by ELISA. (1) Compared with the normal control group, the model control group showed significant increases in facial and ear micro-circulation blood flow, facial temperature and heart rate (P Yin deficiency symptoms of zygomatic red and dysphoria in mice as well as liver function injury caused by overactive thyroid axis. According to its action mechanism, DOF may show yin nourishing and hepatic protective effects by impacting thyroxin substance metabolism, improving micro-circulation and reducing heart rate.

    Since 1942, therapy with radioiodine (Na{sup 131}I) has gained a major role in the treatment of benign thyroid disorders, notably hyperthyroidism caused by Graves' disease or toxic multi nodular goiter. The very large series of patients treated so far offer the opportunity for an assessment of both benign and malignant side effects. Hyperthyroidism is sometimes observed after radioiodine therapy due to radiation induced thyroid hormone or by an immunological mechanism. Despite the numerous attempts to design dosage schedules aiming at euthyroidism, hypothyroidism occurs in the majority of patients throughout life. Transient hypothyroidism may be observed within the first year after therapy and is caused by an immunological mechanism. Radioiodine therapy in Graves' disease may induce or worsen ophthalmopathy, which can be prevented by steroids effectively. Hypoparathyroidism and hyperparathyroidism have been reported after radioiodine therapy but probably do not exceed the normal incidence. Sialitis is commonly observed but mostly in patients treated with radioiodine for thyroid cancer. There are no indications for induction of genetic abnormalities after radioiodine therapy although no definite conclusion can be reached. Much attention has been paid to malignant disease. In very large series, no effects of radioiodine therapy on survival have been observed. Some studies report an increased relative risk for certain types of cancer (notably thyroid cancer, stomach cancer, bladder and kidney cancer or hematological malignancies). However, these observations were not confirmed by other large studies, so that no definite conclusion with respect to risk for certain types of malignant disease can be drawn. However, radioiodine therapy for benign thyroid disorders has generally considered safe and without major side effects, hypothyroidism being the most frequent one.

    Aim: Radioiodine (I-131) is increasingly being considered for the treatment of hyperthyroidism but there is no general agreement for the initial dose. To determine the cost-effectiveness and optimal dose of I-131 to cure disease, we prospectively studied the outcome of radioiodine therapy of 423 patients. Material and Methods: Any of the fixed doses of 6, 8, 10, 12 or 15 mCi of I-131 was administered to the patients relating to thyroid gland size. The individual was excluded from this study who had multinodular goitre and autonomous toxic nodule. Patients were classified as cured if the clinical and biochemical status was either euthyroid or hypothyroid at one year without further treatment by antithyroid drugs or radioiodine. The costs were assessed by analyzing the total cost of care including office visit, laboratory testing, radioiodine treatment, average conveyance and income loss of patient and attendant and thyroxine replacement for a period of 2 years from the day of I-131 administration. Results: The results showed a progressive increase of cure rate from the doses of 6, 8 and 10 mCi by 67%, 76.5% and 85.7% respectively but the cure rate for the doses of 12 and 15 mCi was 87.9% and 88.8% respectively. Cure was directly related to the dose between 6 and 10 mCi but at higher doses the cure rate was increased marginally at the expense of increased total body radiation. There was little variation in total costs, but was higher for low dose-therapy and the cost proportion between the 6 mCi regimen and 10 mCi regimen was 1.04:1. Conclusion: We could conclude that an initial 10 mCi of I-131 may be the optimal dose for curing hyperthyroidism and will also limit the total costs

    In 76 cats with hyperthyroidism, peak thyroidal radioiodine ( 131 I) uptakes and effective half-lives were determined after administration of tracer and therapeutic activities of 131 I. In 6 additional hyperthyroid cats, only peak thyroidal uptakes after administration of tracer and therapeutic activities of 131 I were determined. Good correlation was found between peak thyroidal uptakes of tracer and therapeutic 131 I; however, only fair correlation was observed between effective half-lives. In 79% of the cats, the effective half-life for therapeutic 131 I was longer than that for tracer 131 I. After administration of therapeutic activity of 131 I, monoexponential and biphasic decay curves were observed in 51 and 16 cats, respectively. Using therapeutic kinetic data, radiation doses to the thyroid gland were calculated retrospectively on the basis of 2 methods for determining the activity of 131 I administered: (1) actual administration of tracer-compensated activity and (2) hypothetic administration of uniform activity (3 mCi). Because of the good predictive ability of tracer kinetic data for the therapeutic kinetic data, the tracer-compensated radiation doses came significantly (P = 0.008) closer to the therapeutic goal than did the uniform-activity doses. In addition, the use of tracer kinetic information reduced the extent of the tendency for consistently high uniform-activity doses. A manual method for acquiring tracer kinetic data was developed and was an acceptable alternative to computerized techniques. Adoption of this method gives individuals and institutions with limited finances the opportunity to characterize the iodine kinetics in cats before proceeding with administration of therapeutic activities of 131 I

  4. Implications of the simultaneous occurrence of glycolysis and gluconeogenesis in hepatocytes from normal and hyperthyroid rats

    The mammalian liver has the capability for both glycolysis and gluconeogenesis. In the fasting state, metabolites such as lactate and glycerol, generated in the peripheral tissues, are taken up by the liver and converted to glucose. However, hepatocytes from fasted animals are also capable of substantial rates of glycolysis. It is generally assumed that glycolysis and gluconeogenesis do not occur simultaneously in the same cell, but rather the metabolic conditions that facilitate flux through one pathway impair flow in the opposite direction. The actual direction of flow at any given moment is thought to be determined by regulatory mechanisms that control flux through the enzymatic steps specific to glycolysis and gluconeogenesis. The rates of glycolysis from [6- 3 H]glucose and gluconeogenesis from [U- 14 C]glycerol were determined in isolated hepatocytes from fasted normal and hyperthyroid rats. We observed that glycolysis from glucose and glucose synthesis from glycerol occurred simultaneously at substantial rates in hepatocytes from normal rats and that gluconeogenesis, but not glycolysis, was increased twofold in hepatocytes from thyroid treated rats. In the hyperthyroid state, the rate of glycolysis from glucose was approximately equal to the rate of glucose formation from glycerol. Hence, metabolism and ATP turnover were stimulated without substantially altering steady-state concentrations of glucose. The concomitant operation of hepatic glycolysis and gluconeogenesis may be a mechanism that accounts in part for the calorigenic effect of thyroid hormone. Since hepatocyles are generally impermeable to phosphorylated metabolites, our observations suggest that glycolysis, and phosphorylation of glycerol take place in the same cells, and that the occurrence of simultaneous glycolysis and gluconeogenesis is an indication of channelling within the hepatocyte cytoplasm of individual hepatocytes

    Full text: Radioiodine therapy is a well-established method for the treatment of patients with various forms of hyperthyroidism and is preferred in many countries as the first line therapy. Traditionally, it has been applied in Bulgaria in low doses, mainly in elderly patients with contraindications for surgery or after long-term antithyroid drug therapy. No systematic follow up of these patients has ever been done in the country. Materials and Methods: 571 subjects aged 34 to 79 years (mean 64, 7), 108 males with mean age of 68.61 years (54 to 76 yrs) and 463 females with mean age of 68.89 years (34 to 84 yrs). Mean disease duration was 73±5 months. The study included 296 patients with toxic nodular goiter, 220 patients with Graves- Basedow disease and Hashitoxicosis and 55 patients with adenoma toxicum. 256 females and 40 males with toxic nodular goiter, 158 females and 62 males with Graves- Basedow disease and Hashitoxicosis, 49 females and 6 males with adenoma toxicum. The disease duration is 48.19 months in females and 22.5 months in males. Methods: 131-iodine scan and uptake before the treatment and on follow-up visits at months 6,12,18 and 24 with a dose of 1.48 MBq 131-I for the both tests, given orally as a water solution. Uptake was measured at hours 2, 4 and 24; thyroid scan -at hour 24, thyroid ultrasound, FNB cytology if suspicious of malignancy, thyroid hormones -TSH (normal range 0.3-4.0 mU/l), FT4 (normal range 8-17 pmol/l) Results: 131-iodine therapy was administered to subjects with 131-I uptake over 25% at hour 24. Doses between 148- 370MBq were given depending on diagnosis and thyroid volume. A single radioiodine dose, mean value 189.07 MBq is applied in 246 (87, 85%) patients, second dose, mean value 183, 5 MBq is required in 30 (10, 72%) and third dose, mean value 148 MBq received 4 (1, 43%) patients. Effect of 131-iodine therapy-the change in radioiodine uptake is a marker for complex assessment of the result of the 131-iodine therapy. In

    Full Text Available Abstract Background Hyperthyroidism is accompanied by osteoporosis with higher incidence of fracture rates. The present work aimed to study bone status in hyperthyroidism and to elucidate the impact of severity, duration, and etiology of hyperthyroidism on biochemical markers of bone turnover and bone mineral density (BMD. Methods Fifty-two male patients with hyperthyroidism, 31 with Graves' disease (GD and 21 with toxic multinodular goiter (TNG, with an age ranging from 23 to 65 years were included, together with 25 healthy euthyroid men with matched age as a control group. In addition to full clinical examination, patients and controls were subjected to measurement of BMD using dual-energy X-ray absorptiometery scanning of the lower half of the left radius. Also, some biochemical markers of bone turnover were done for all patients and controls. Results Biochemical markers of bone turnover: included serum bone specific alkaline phosphatase, osteocalcin, carboxy terminal telopeptide of type l collagen also, urinary deoxypyridinoline cross-links (DXP, urinary DXP/urinary creatinine ratio and urinary calcium/urinary creatinine ratio were significantly higher in patients with GD and TNG compared to controls (P 0.05. BMD was significantly lower in GD and TNG compared to controls, but the Z-score of BMD at the lower half of the left radius in patients with GD (-1.7 ± 0.5 SD was not significantly different from those with TNG (-1.6 ± 0.6 SD (>0.05. There was significant positive correlation between free T3 and free T4 with biochemical markers of bone turnover, but negative correlation between TSH and those biochemical markers of bone turnover. The duration of the thyrotoxic state positively correlated with the assessed bone turnover markers, but it is negatively correlated with the Z-score of BMD in the studied hyperthyroid patients (r = -0.68, P Conclusion Men with hyperthyroidism have significant bone loss with higher biochemical markers of bone

    Temporary disability is the condition that workers face when, as the result of illness (common or professional) or accident (work-related or not), they are temporarily prevented from performing their work and require health care. The management of temporary disability is a medical act that involves (in addition to a complex clinical assessment) obvious social, occupational and financial connotations and requires continuing medical follow-up from doctors, as well as responses to medical-legal conflicts. The regulatory framework on the subject is extensive in the Spanish setting and highly diverse in the European setting. Beyond the regulatory framework, the repercussions of temporary disability are self-evident at all levels. Although determining temporary disability is a common medical act for practicing physicians, it is not exempt from risks or difficulties arising from the assessment itself and the characteristics of practicing medical care. Established medical-legal conflicts include the processing of health data and the requirements for transferring information related to workers' temporary disability to their company's medical services. The interest and usefulness demonstrated by the data obtained from forensic medicine for public health require the incorporation of these data into general healthcare information, as it could be essential to the surveillance of worker health. The recommendations established by medical societies, as good practice guidelines, are especially useful in this type of conflict. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    The medical records of 62 hyperthyroid cats treated with a fixed dose of 4 mCi of radioactive iodine (131I) were reviewed. In 60 cats, serum thyroxine concentrations were determined after treatment, allowing evaluation of treatment success. Eighty-four percent of the cats had normal serum thyroxine concentrations after treatment. Five of the 60 cats (8%) remained hyperthyroxinemic after treatment. Five cats (8%) were hypothyroxinemic when evaluated within 60 days of treatment. Three of these cats had normal serum thyroxine concentrations 6 months after treatment, and none had clinical signs of hypothyroidism. The administration of a fixed dose of 4 mCi of 131I was determined to be an effective treatment for feline hyperthyroidism

    Feline hyperthyroidism is the most common endocrinological disorder of older cats. Diagnosis is established by assessment of thyroid stimulating hormone (TSH) and free thyroxine (FT4). In hyperthyroidism FT4 is found up to ten times above the normal range. Thyroid scintigraphy using {sup 99m}Tc-pertechnetate shows goiter size, which can reach more than 20 ml, and differentiates between unifocal and multifocal thyroid adenoma. In rare cases, ectopic tracer accumulation may be found, suggesting thyroid carcinoma. Radioiodine is the safest, simplest and most effective treatment for benign thyroid disease in the cat. Normal thyroid function is usually established within two weeks. Practical and legal radiation protection rules are strictly to be observed. Even so, the rapid elimination of {sup 131}I usually allows patient discharge within one week. Internal and external radiation risks are very low for clinic staff and cat owners. (orig.)

    Full Text Available   Objective(s: Previous studies have shown that thyroid hormones are necessary for normal development of many organs and because of the importance of skin as the largest and the most important organ in human body protection in spite of external environment, the study of thyroid hormones effects on skin development is considerable. In this survey we have tried to study the effects of maternal hypothyroidism on skin development in fetus during pregnancy and lactation by immunohistochemistry technique.   Materials and Methods: Rats were divided into 4 groups, hypothyroids, hyperthyroids, hypothyroids are treated with levothyroxin and a control group. The rat mothers were exposed to PTU with 50 mg/lit dosage and levothyroxin with 1 mg/lit dosage and PTU and levothyroxin simultaneously and with the same dosage respectively in hypothyroid, hyperthyroid and treated hypothyroids with levothyroxin groups. After 14 days, blood sample was taken from mothers, and if thyroid hormones level had change well, mating was allowed. After pregnancy and delivery, 1th day dorsal skin (as the sample for pregnancy assay and 10th day skin (as for lactation assay was used for immunohystochemical and morphometric studies. Results: In this study it was observed that maternal hypothyroidism during pregnancy and lactation causes significant increase in laminin expression, in most areas of skin, and maternal hyperthyroidism during pregnancy and lactation causes significant decrease in laminin expression. Also significant decrease was observed in hair follicles number and epidermis thickness in hypothyroidism groups. Conclusion: This study showed maternal hypothyroidism causes significant decrease in epidermis thickness and hair follicles number and it causes less hair in fetus. Also maternal hypothyroidism causes large changes in laminin expression in different parts of skin. At the same time,maternal hyperthyroidism causes opposite results. In fact, thyroid hormones

    Radioactive iodine (RAI) is commonly used in the treatment of hyperthyroidism but is not uniformly successful. Lithium increases thyroidal iodine retention without reducing iodide uptake, increasing the radiation dose to the thyroid when administered with RAI. Although these actions suggest that adjuvant lithium may increase the efficacy of RAI, its role as an adjunct to RAI remains contentious. To evaluate the safety and efficacy of adding lithium to RAI to treat hyperthyroidism. Relevant studies were identified by a search of Medline and the Cochrane Central Register of Controlled Trials. To be included, a study had to be a controlled trial comparing the effect of RAI alone to RAI with lithium in the treatment of hyperthyroidism. Relevant data were extracted and meta-analyses were performed. Of the 75 identified studies, 6 met the inclusion criteria; 4 of these studies were interventional and 2 were observational trials. Meta-analysis of the observational trials (N = 851), both of which were retrospective cohort studies, showed significant improvement in the primary outcome (i.e., cure rate) with adjunctive lithium (odds ratio [OR], 1.92; 95% confidence interval [CI], 1.24 to 2.96). The combined interventional trials (N = 485) also showed an improvement in cure rate, but the difference did not reach statistical significance (OR, 1.28; 95% CI, 0.85 to 1.91). Adjunctive lithium reduced time to cure and blunted thyroid hormone excursions after RAI. Lithium-related side effects were infrequent and usually mild. The observational trials demonstrated significant improvement in the cure rate of hyperthyroidism when lithium is added to RAI. The improvements shown in the interventional trials did not reach statistical significance due to the effect of a single, large negative trial.

    Thyroid hormone producing thyroid carcinoma is an uncommon cause of thyrotoxicosis. A patient with extensive hepatic metastases from well-differentiated carcinoma is presented. Administration of amiodarone for atrial fibrillation led to the development of hyperthyroidism. Precipitation of thyrotoxicosis by iodine-containing compounds in patients with thyroid carcinoma is rare. The relatively high iodine load and the slow elimination of amiodarone complicate the clinical management of such patients.

    2014-01-01

    Full Text Available Introduction. Liver involvement due to hyperthyroidism and also ANCA positive vasculitis related renal failure cases were reported separately several times before. However, to our knowledge, these two complications together in the same case had never been observed before. Case Presentation. The case of an ANCA positive 71-year-old Caucasian male with renal failure and lung involvement, subclinical hyperthyroidism, and intrahepatic cholestatic jaundice was presented in this paper. After exclusion of all of the other possibilities, cholestatic hepatitis was explained by subclinical hyperthyroidism; renal failure and lung involvement were interpreted as ANCA related vasculitis which might be a side effect of propylthiouracil use. Conclusion. The coexistence of these rare conditions in the same patient deserves emphasis and it is worth reporting. This case demonstrates that following the clinical course of the patient is essential after prescribing any medications to see whether any complication occurs or not. If the complications of this case were noticed earlier, it would be possible to treat and to prevent the permanent damages.

    A very rare association of non-autoimmune hyperthyroidism due to nodular goiter with isolated bilateral non-Hodgkin's ocular lymphoma is described. A 66-year-old woman presented with bilateral proptosis, marked periocular swelling, conjunctival hyperemia and chemosis, severe extraocular muscle impairment with diplopia. Thyroid function tests showed normal free thyroid hormone concentrations with undetectable serum thyrotropin levels. Patient was placed on antithyroid drug treatment, ocular conditions deteriorated. More than two years later, when first seen in our institution, orbital CT scan showed the presence of a retro-ocular mass that, at biopsy, proved to be B-cell non-Hodgkin's lymphoma, apparently with no localization in other sites. Thyroid evaluation revealed subclinical hyperthyroidism due to an autonomous thyroid nodule in the left lobe of the gland. Radiotherapy of the orbit was followed by a dramatic regression of lymphoma, but further staging some months later showed involvement of several abdominal lymph node structures. This case underscores the need of a thorough diagnostic work-up of ocular disease resembling Graves' ophthalmopathy, even when it is bilateral and associated with overt or subclinical hyperthyroidism.

    A follow-up study of 1762 hyperthyroid women who were treated at the Massachusetts General Hospital Thyroid Unit between 1946 and 1964 was conducted. The average length of follow-up was 17.2 years. A 1978 mailing address or a death certificate was located for 92% of the women, and 88% of 1058 living patients responded to a mail questionnaire. The standardized mortality ratio (SMR) for all causes of death was 1.3 (95% confidence interval (CI) 1.2-1.4). The standardized mortality ratios for all malignant neoplasms and for breast cancer were 0.9 (95% CI 0.7-1.1) and 1.3 (95% CI 0.8-1.9), respectively. More deaths than expected were observed from endocrine and metabolic diseases (SMR = 1.8, 95% CI 1.2-2.7), circulatory system diseases (SMR = 1.4, 95% CI 1.3-1.6), and respiratory system diseases (SMR = 1.9, 95% CI 1.3-2.6). The standardized incidence ratios (SIR) for all malignant neoplasms and for breast cancer were 0.9 (95% CI 0.8-1.1) and 1.2 (95% CI 0.9-1.5), respectively. A nonsignificant excess breast cancer risk was observed 10 years after the onset of thyroid symptoms and was present at the end of 30 years of observation. A statistically significant excess number of pancreatic cancer cases (SIR = 2.0, 95% CI 1.0-3.7) and a nonsignificant excess of brain cancer cases (SIR = 2.3, 95% CI 0.7-5.3) were observed. Eighty per cent of the women were treated with radioactive iodine. When age at treatment and year of treatment were controlled, women who were ever treated with radioactive iodine had a standardized rate ratio for breast cancer of 1.9 (95% CI 0.9-4.1), compared with those who were never treated with radioactive iodine. Women who developed hypothyroidism as a result of their treatment for hyperthyroidism did not have an increased risk of developing breast cancer (SIR = 1.1, 95% CI 0.8-1.6)

    Full text: Nuclear Medicine practices involve use of radioisotopes for diagnosis and treatment of diseases. Radioiodine is one of such radioisotopes, being used in the diagnosis and treatment of diseases since 1942. Handling of radioiodine involves radiation hazards both for the patients as well as for the technologists. Though radioiodine is supplied in a lead container, for treatment purpose, it is administered after dispensing into a glass jar that does not adequately protect radiation hazards. For this reason, we designed and developed a lead jar and radioiodine is dispensed into that lead jar to minimize radiation hazards. For oral administration of radioiodine to hyperthyroid patients, a lead jar was designed and developed with lead in Centre for Nuclear Medicine and Ultrasound, Khulna in December 2004 by own expertise and technologies in such a way that a glass jar could be introduced into that lead jar. The thickness of lead was 4.04 mm and the thickness of glass jar was 0.7 mm and thus the whole thickness of lead jar became 4.74 mm. The desired dose of radioiodine (8 mCi) that should be given to the patients were dispensed into that lead jar and administered orally to the patients. Radiation levels in 10 such cases were measured by Mini-Rad Series-1000 survey meter at 0.5 meter, 1 meter and 3 meters distances both lead jar and glass jar. The mean radiation level of lead jar and glass jar during oral administration of 8 mCi of Na 131 I solution in 10 cases at 0.5 meter, 1 meter and 3 meters distances were 62.4 ± 1.96 microSv/h, 17.7 ±1.95 microSv/h, 3.39 ± .12 microSv/h and 20.3± 2.16 microSv/h, 79.8 ± 0.79 microSv/h, 1.97 ± 0.23 microSv/h respectively. We have found that radiation level reduced by 67.47%, 61.58%, and 41.89% with lead jar at 0.5 meter, 1 meter and 3 meters distances. In conclusion, the locally designed and developed lead jar is safe, easy to handle and reduces radiation burden significantly in oral administration of radioiodine to

    Possible thrombogenic effects of degradable starch microspheres were investigated. Controlled temporary small intestinal ischaemia was induced by injection into the superior mesenteric artery in cats. Arterial flow consistently recovered after ischaemia. No consumption of blood platelets, fibrinogen, or Factor VIII was observed. Aggregation of human platelets was not influenced by microsphere exposure, and platelet retention in starch microsphere columns was minimal. No thrombosis was detected in feline small intestinal vessels in vivo nor did starch surfaces induce adhesion or aggregation of human platelets in vitro. Thus, no evidence of thrombotic hazards was found by inducing temporary intestinal ischaemia by starch microspheres. (Auth.)

    Full Text Available Objectives: The present study was carried out to determine whether thyroid hormones affect lipid profile and levels of erithrocyte sedimentation rate (ESR, serum total homocysteine (t-hcy, leptin, fibrinogen, C-reactive protein (CRP in patients with hyperthyroidism.Materials and methods: This study was carried out on 23 hyperthroid subjects (3 men / 20 women, mean age 41.8 ± 2.4 years. Serum levels of homocysteine, leptin, fibrinogen, CRP, total cholesterol (TC, high-density lipoprotein cholesterol (HDL-C, low-density lipoprotein cholesterol (LDL-C and ESR were measured and body mass index (BMI were calculated before and after treatment of hyperthyroidism.Results: Pretreatment t-hcy, TC, LDL-C, HDL-C levels and BMI of patients were significantly lower than those of the post-treatment (p<0.001, for each variable. However, fibrinogen and ESR decreased after the treatment (p<0.001 and p<0.05, respectively. There were no differences in leptin and CRP levels between pre- and post-treatment periods. Pre and post treatment TC and LDL-C levels were negatively correlated with free triiodothyronine (fT3 levels (r=-0.588, p<0.01; r=-0.534, p<0.01; r=-0.543, p<0.01 and r =-0.653, p<0.01, respectively. Pre-treatment HDL-C was inversely correlated with TSH (r=-0.423, p<0.05. Pre-post- treatment LDL-C was negatively correlated with free thyroxine (fT4 levels (r=-0.536, p<0.001 and r=- 0.422, p<0.05 respectively. Pre-treatment TC was inversely correlated with fT4 (r=-0.590, p<0.01.Conclusion: Hyperthyroidism is associated with high plasma fibrinogen and ESR levels. Elevated plasma fibrinogen and ESR levels may be a possible explanation for the high cardiovascular morbidity among hyperthyroidic subjects. These changes may reflect low-grade inflammation or disturbances in coagulation in hyperthyroidism.

    Full text: Introduction: Radioiodine (RAI) 131 I has became a widely used therapy for patients with hyperthyroidism due to GD. It is controversial which the dose to apply in such patients is. Administration of low doses of 131 I, oriented to decrease the incidence of hypothyroidism, may delay or fail to cure the hyperthyroidism. Objective: We designed this study to compare the frequencies of cure and persistence/recidive (P/R) of the hyperthyroidism using 2 different fixed dose protocols, also to evaluate the presence of complications after such doses. Subjects and Methods: Seventy six patients who received 131 I therapy for GD between 1997 and 2004 were evaluated. All of them had received initial treatment with methimazole, relapsing the hyperthyroidism after drug withdrawal. Patients were divided into 2 groups considering the RAI dose administered. Group 1 (n=32): 300 μCi/g retained at 24 h; and Group 2 (n=44): 100 μCi/g retained at 24 h. Both groups were comparable when age, gender and thyroid weight were considered. Results: The frequency of cure was 87.5% (28/32) in Group 1 vs. 45.5% (20/44) in Group 2 (p<0.0003). Hypothyroidism was observed in 96.5% (27/28) of cured patients in Group 1 vs. 85% (17/20) of cured patients in Group 2 (p=NS). P/R was observed in 28 patients. Twenty five of them received a new RAI dose (3 in Group 1 and 22 in Group 2) and two had received a third dose. After this procedure 87.5 % became hypothyroid within one year of follow up. No adverse events were observed in these patients, except for hypothyroidism. Conclusion: High dose RAI therapy in GD resulted in earlier and better rates for the control of thyrotoxicosis. Rates of hypothyroidism were similar in both groups, with the difference that those subjects, who originally received a low dose of RAI, were creeping in a winding path, rendering a poor quality of life, and finally arriving at the same hypothyroid state than the others. Therefore, we recommend high RAI doses for the

    Optimization and verification of Patient-Specific Treatment Planning with unsealed I-131 sources is a desirable goal from medical and radiation protection point of view. To obtain a practical protocol to combine the estimation of the related parameters with patient's specific treatment dose in hyperthyroidism disease, 3 equipment were studied (Iodine Probe, a Philips Forte Camera with pin-hole collimators and a Mediso Nucline with HEGP for planar and SPECT techniques) and crossed calibrated. The linear behaviour on diagnostic and therapeutic activity range was verified, showing a linear correlation fitting factor R 2 > 0.99. The differences between thyroid uptake determinations in all equipment were less than 6% for therapeutic activities and less than 1.1% in the diagnostic range. The combined protocol to calculate, with only one administration of I 131 , all the necessary parameters to the treatment dose estimation in 2D or 3D, avoiding wasting time with gamma cameras, was established and verified. Following this protocol the difference between apparent and calculated activities were less than 3%. (Author)

    Samples of thyroid tissue removed surgically from 63 patients were cultured in vitro and X-irradiated to investigate the radiosensitivities of various types of thyroid epithelial cells. A total of 76 samples were obtained, including neoplastic cells from patients with papillary carcinoma (PC) or follicular adenoma (FA), cells from hyperthyroidism (HY) patients, and normal cells from the surgical margins of PC and FA patients. Culturing of the cells was performed in a manner which has been shown to yield a predominance of epithelial cells. Results of colony formation assays indicated that cells from HY and FA patients were the least radiosensitive: when adjusted to the overall geometric mean plating efficiency of 5.5 %, the average mean lethal dose D 0 was 97.6 cGy for HY cells, and 96.7 cGy and 94.3 cGy, respectively, for neoplastic and normal cells from FA patients. Cells from PC patients were more radiosensitive, normal cells having an adjusted average D 0 of 85.0 cGy and PC cells a significantly (p = .001) lower average D 0 of 74.4 cGy. After allowing for this variation by cell type, in vitro radiosensitivity was not significantly related to age at surgery (p = .82) or sex (p = .10). These results suggest that malignant thyroid cells may be especially radiosensitive. (author)

  5. Narcolepsy with cataplexy and hyperthyroidism sudden appeared after H1N1 vaccination

    Directory of Open Access Journals (Sweden)

    Silvia Leiva

    Full Text Available Narcolepsy type 1 (NT1 is a chronic sleep disorder, characterized by excessive daytime sleepiness, cataplexy and fragmented nocturnal sleep. It is caused by a hypocretin deficiency due to a significant reduction of the neurons producing it. In the last years, it has been postulated that an autoimmune mechanism would be responsible for the destruction of these neurons in those genetically predisposed patients. The increased incidence of narcolepsy after the pandemic H1N1 influenza vaccination campaign in 2009-2010 is known. We present below the case of an adult patient who, 10 days after receiving H1N1 vaccination, suffers a traffic accident after falling asleep. Subsequent studies revealed hyperthyroidism due to Graves disease. In spite of the treatment, the patient persisted with daily and disabling daytime sleepiness, sleep attacks and episodes of generalized muscle atony with preservation of consciousness. A nocturnal polysomnography and multiple sleep latency test (MSLT were performed with a diagnosis of NT1. The particularity of this case is the presentation of 2 autoimmune diseases triggered by an H1N1 vaccine without adjuvant, so far there is only evidence of NT1 associated with vaccines with adjuvant and viral infection. The association of both entities has made us reflect on the autoimmune mechanism, reinforcing the theory of its role in the onset of the disease.

    Amiodarone is a potent antiarrhythmic agent, indicated for the treatment of refractory arrhythmias, which may lead to thyrotoxicosis. In these patients, thyroidectomy is a valid therapeutic option. Antithyroid therapy in the immediate preoperative setting and the subsequently accepted minimal delay until thyroidectomy have not been clearly defined yet. The aim of the present study was to show, that total thyroidectomy under general anaesthesia in patients with amiodarone-induced thyrotoxicosis (AIT) is safe without necessarily obtaining an euthyroid state preoperatively.We conducted a retrospective cohort study of prospectively gathered data on 11 patients undergoing total thyroidectomy under general anaesthesia between January 2008 and December 2013 for AIT at our University Hospital.All patients were preoperatively treated with carbimazole, steroids and β-receptor antagonists. Additionally, 3 patients received potassium perchlorate and in one patient carbimazole was changed to propylthiouracil. Plasmapheresis was performed in 3 patients. Only one patient was euthyroid at the time of operation. There were no significant intra- and postoperative complications, especially no signs of thyroid storm. One patient could postoperatively be removed from the cardiac transplant waiting list due to improved cardiac function.Improvements in the interdisciplinary surgical management for AIT between cardiologists, endocrinologists, anaesthetists and endocrine surgeons provide the basis of safe total thyroidectomy under general anaesthesia in hyperthyroid state. Early surgery without long delay for medical antithyroid treatment (with its potential negative side effects) is recommended. © Georg Thieme Verlag KG Stuttgart · New York.

    There are many issues regarding the use of real patients in objective structured clinical examinations (OSCEs). In dermatology OSCE stations, standardised patients (SPs) with clinical photographs are often used. Temporary transfer tattoos can potentially simulate skin lesions when applied to an SP. This study aims to appraise the use of temporary malignant melanoma tattoos within an OSCE framework. Within an 11-station OSCE, a temporary malignant melanoma tattoo was developed and applied to SPs in a 'skin lesion' OSCE station. A questionnaire captured the opinions of the candidate, SP and examiners, and the degree of perceived realism of each station was determined. Standard post hoc OSCE analysis determined the psychometric reliability of the stations. The response rates were 95.9 per cent of candidates and 100 per cent of the examiners and SPs. The 'skin lesion' station achieved the highest realism score compared with other stations: 89.0 per cent of candidates felt that the skin lesion appeared realistic; only 28 per cent of candidates had ever seen a melanoma before in training. The psychometric performance of the melanoma station was comparable with, and in many instances better than, other OSCE stations. Transfer tattoo technology facilitates a realistic dermatology OSCE station encounter. Temporary tattoos, alongside trained SPs, provide an authentic, standardised and reliable experience, allowing the assessment of integrated dermatology clinical skills. © 2013 John Wiley & Sons Ltd.

  10. Meaningful radiation worker training for temporary craftsmen

    The carefully organized Radiation Worker Training Program presented to permanently assigned personnel at a power reactor facility too often falls by the wayside when temporary craftsmen are brought in for an outage. Even though these temporary workers will frequently be assigned to outage jobs with high radiation and/or contamination exposures, their Radiation Worker Training is often squeezed into an already busy schedule, thus reducing its effectiveness. As an aid for evaluating the effectiveness of an existing Radiation Worker Training Program for temporary craftsmen or for setting up a new program, the following guides are presented and discussed in this paper: the training environment; the interest and meaningfulness of the presentation; the method or methods used for presentation of the training information; the use of demonstrations; trainee participation; and, measuring the amount and type of information retained by a trainee. Meaningful Radiation Worker Training for temporary craftsmen can pay big dividends. Craftsmen can be expected to make fewer mistakes, thus reducing radiation exposure and lessening the chance for the spread of contamination. The craftsmen will also benefit by being able to work longer and utility management will benefit by having lower outage costs

    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

    Full text of publication follows. Aim: the present study aims to evaluate radiation exposure of owners and veterinary staff members after 131 I treatment of hyperthyroid cats. Additionally, radiation dose rates from the treated cats were measured at different time points to analyze the effective half-life of 131 I within the cat. Materials and methods: 28 cats received a mean activity of (173 ± 84) MBq of 131 I. During the 5 day hospitalization period, the veterinary staff (3 persons) involved in the care for these cats wore waterproof bracelets and rings (at left and right hand) containing calibrated (LiF:Mg,Cu,P) thermoluminescent dosimeters (TLDs). TLDs were read out after 5 days and readings were converted in a dose value using an in-house measured calibration factor. Further, equivalent dose rates (μSv/h) were registered at 1 m distance from the cat at 4 h, 24 h, 48 h and 72 h after injection. The dose rates were plotted against time and fitted to an exponential function. From the fitting results, the effective half-life (T 1/2eff ) could be calculated. Owners were also given waterproof bracelets containing TLDs at the moment their cat was released from the Veterinary Nuclear Medicine Division. They were given strict instructions concerning the management of the cat at home (emphasizing limited time, keeping distance and waste management). The bracelets were returned by mail after 1 week together with the owners' estimation of the time spent with the cat. TLDs doses were analyzed using the aforementioned procedure. Results: 4 hours after injection, mean equivalent dose rate at 1 m was (9 ± 4) μSv/h. This value further decreased to (4 ± 3) μSv/h. Based on the dose rate measurements a mean T 1/2eff of (3.0 ± 1.6) days was found. Over 7 days, the average accumulated wrist dose of the owners was 504 μSv (range 26-2682 μSv). Concerning staff members, mean accumulated wrist doses over 5 days were 101 μGy and 120 μGy for left and right wrists

A cada 14 dias foram colhidas amostras de soro para a determinação da concentração da tiroxina total (T4, tiroxina livre (FT4, paratormônio intacto (PTH, cálcio total e ionizado, fósforo e, além disso, realizaram-se radiografias para a determinação da densidade mineral óssea (DMO. Observou-se aumento das concentrações séricas do PTH a partir do momento inicial (M0, com diferença significativa deste em relação às concentrações obtidas aos 14 (M1, 28 (M2 e 42 (M3 dias. Não houve diferença significativa nas concentrações séricas de cálcio total e fósforo entre todos os momentos. O cálcio ionizado diminui de M0 para M1 e de M1 para M3, com diferença significativa. Os hormônios tireoidianos apresentaram correlação positiva com o PTH e negativa com o cálcio ionizado. A correlação entre DMO e PTH a partir de M2 foi negativa e entre DMO e fósforo foi negativa somente em M2. Não se observou correlação entre DMO e as demais variáveis. Em M1, M2 e M3 foi observada correlação negativa entre o PTH e o cálcio ionizado. Conclui-se que o hipertireoidismo em gatos adultos jovens está associado ao hiperparatireoidismo secundário devido ao aumento do PTH e diminuição do cálcio ionizado. Os efeitos combinados dos hormônios tireoidianos e do PTH contribuíram para a diminuição da DMO.The effect of experimental hyperthyroidism, 150µg/kg/day/42 days, on calcium homeostasis was studied in 14 mongrel cats aging from one to three-year-old.

  18. Cerebral cortex hyperthyroidism of newborn mct8-deficient mice transiently suppressed by lat2 inactivation.

    Directory of Open Access Journals (Sweden)

    Bárbara Núñez

    Full Text Available Thyroid hormone entry into cells is facilitated by transmembrane transporters. Mutations of the specific thyroid hormone transporter, MCT8 (Monocarboxylate Transporter 8, SLC16A2 cause an X-linked syndrome of profound neurological impairment and altered thyroid function known as the Allan-Herndon-Dudley syndrome. MCT8 deficiency presumably results in failure of thyroid hormone to reach the neural target cells in adequate amounts to sustain normal brain development. However during the perinatal period the absence of Mct8 in mice induces a state of cerebral cortex hyperthyroidism, indicating increased brain access and/or retention of thyroid hormone. The contribution of other transporters to thyroid hormone metabolism and action, especially in the context of MCT8 deficiency is not clear. We have analyzed the role of the heterodimeric aminoacid transporter Lat2 (Slc7a8, in the presence or absence of Mct8, on thyroid hormone concentrations and on expression of thyroid hormone-dependent cerebral cortex genes. To this end we generated Lat2-/-, and Mct8-/yLat2-/- mice, to compare with wild type and Mct8-/y mice during postnatal development. As described previously the single Mct8 KO neonates had a transient increase of 3,5,3'-triiodothyronine concentration and expression of thyroid hormone target genes in the cerebral cortex. Strikingly the absence of Lat2 in the double Mct8Lat2 KO prevented the effect of Mct8 inactivation in newborns. The Lat2 effect was not observed from postnatal day 5 onwards. On postnatal day 21 the Mct8 KO displayed the typical pattern of thyroid hormone concentrations in plasma, decreased cortex 3,5,3'-triiodothyronine concentration and Hr expression, and concomitant Lat2 inactivation produced little to no modifications. As Lat2 is expressed in neurons and in the choroid plexus, the results support a role for Lat2 in the supply of thyroid hormone to the cerebral cortex during early postnatal development.

    Ketones, including beta hydroxybutyrate (BHB), are produced in conditions of negative energy balance and decreased glucose utilization. Serum BHB concentrations in cats are poorly characterized in diseases other than diabetes mellitus. Serum BHB concentrations will be increased in cats with chronic kidney disease (CKD), hyperthyroidism (HT), or hepatic lipidosis (HL). Twenty-eight client-owned cats with CKD, 34 cats with HT, and 15 cats with HL; 43 healthy cats. Prospective observational study. Serum BHB concentrations were measured at admission in cats with CKD, HT, and HL, for comparison with a reference interval established using healthy cats. Results of dipstick urine ketone measurement, when available, were compared to BHB measurement. Beta hydroxybutyrate was above the reference interval (<0.11 mmol/L) in 6/28 cats (21%) with CKD, 7/34 cats (20%) with HT, and 11/15 cats (73%) with HL, significantly exceeding the expected 2.5% above the reference interval for healthy cats (P < .001 for all groups). Elevations were mild in CKD and HT groups (median BHB 0.1 mmol/L for both groups, 80th percentile 0.12 and 0.11 mmol/L, respectively), but more marked in HL cats (median BHB 0.2 mmol/L, 80th percentile 0.84 mmol/L). None of 11 cats with increased serum BHB concentration having urine dipstick analysis performed within 24 h of sampling for BHB were ketonuric. Increases in serum BHB concentrations occur in cats with CKD, HT, and HL, and might provide an useful index of catabolism. Copyright © 2016 The Authors.

Radioiodine therapy is associated with dry eyes and some side effects are seen especially due to beta rays. In this study, the functional and cytological status of lacrimal glands after RAI therapy was evaluated. Twenty-five patients with a mean age of 55.16 years with planned low-dose RAI therapy were evaluated. Just before and 6 months after the treatment, the lacrimal glands were evaluated with tear break-up time (BUT), Schirmer's test, impression cytology and ''Ocular Surface Disease Index (OSDI)'' questionnaire. The mean value of Schirmer's test was 16.20±3.61 pre-treatment and 11.28±4.39 post-treatment for the right eye, and 15.76±3.27 and 10.60±4.42 for the left eye, respectively. The mean value of Schirmer's test decreased significantly post-treatment in both eyes (p=0.0001). The BUT score also decreased significantly post-treatment (p=0.001). The mean value of OSDI score was 27.5±8.02 pre-treatment and 46.36±10.27 post-treatment. The mean value of OSDI score increased post-treatment (p=0.0001). The impression scores also increased post-treatment in both eyes (p=0.0001). Even low-dose (≤30 mci) RAI treatment affects lacrimal gland functions. Low-dose RAI causes a decrease in the value of Schirmer's test and the BUT test, and an increase in the value of OSDI score and impression scores. (author)

    Thyrotoxicosis is a common disease resulting from an excess of thyroid hormones, which affects many organ systems. The clinical symptoms and signs are relatively nonspecific and can vary depending on age, sex, comorbidities, and the duration and cause of the disease. Several symptom rating scales have been developed in an attempt to assess these symptoms objectively and have been applied to diagnosis or to evaluation of the response to treatment. The aim of this study was to assess the reliability and validity of the Korean version of the hyperthyroidism symptom scale (K-HSS). Twenty-eight thyrotoxic patients and 10 healthy subjects completed the K-HSS at baseline and after follow-up at Seoul National University Bundang Hospital. The correlation between K-HSS scores and thyroid function was analyzed. K-HSS scores were compared between baseline and follow-up in patient and control groups. Cronbach's α coefficient was calculated to demonstrate the internal consistency of K-HSS. The mean age of the participants was 34.7±9.8 years and 13 (34.2%) were men. K-HSS scores demonstrated a significant positive correlation with serum free thyroxine concentration and decreased significantly with improved thyroid function. K-HSS scores were highest in subclinically thyrotoxic subjects, lower in patients who were euthyroid after treatment, and lowest in the control group at follow-up, but these differences were not significant. Cronbach's α coefficient for the K-HSS was 0.86. The K-HSS is a reliable and valid instrument for evaluating symptoms of thyrotoxicosis in Korean patients. Copyright © 2018 Korean Endocrine Society.

    Serum thyroid hormone and basal and post TRH stimulated levels of TSH were measured in 48 female subjects of mean age 29.3 ± 9.2 and mean gravida 2.9 ± 2.6 with trophoblastic disease (TD), both benign and malignant. Normal pregnant women (n=21) served as controls. Twenty-five patients showed a normal response to TRH (Group i) while the rest (Group ii) had subnormal response while thyroid hormone levels were increased. Two subgroups iiA and iiB were formed within Group ii on the basis of the free T 4 levels (measured by equilibrium dialysis) falling below or above the 25th percentile. hCG levels were higher in Group ii than in Group i and a stepwise significant increase in the mean level of this hormone was observed in Group i to iiA and iiB. Significant correlation between hCG levels and those of thyroxine, free thyroxine, and triiodothyronine were found in TD patients as a whole, but not within the different subgroups. Clinical signs were minimal, with proximal muscle weakness and fine finger tumours observed in 10 patients in Group iiB. The study shows that the incidence of biochemical hyperthyroidism is higher than was reported before sensitive methods for TSH measurement were available, and postulates that increased hCG concentrations in themselves and/or abnormal metabolic variants of hCG produced by trophoblastic tumours may act as thyroid stimulators in this condition. 64 refs, 5 figs, 4 tabs

    The absolute iodine intake, slowly ameliorated, in a population influences the epidemiology of thyroid carcinoma (TC) and of hyperthyroidism (HT). We have retrospectively evaluated the frequencies of associated TC and HT in a pre-Alpine region over a period amounting up to more than 30 years. The iodide salt (5 - 10 - 20 mg KI/kg since 1922 - 1962 - 1980) have progressively corrected the severe iodine deficit, prevailing at the beginning of century. The patients treated for TC by surgery and/or {sup *}I in our hospital have been grouped in 3 periods: A (before 1971), B (1971 - 1983) and C (1984 - 1996), according to the diagnosis of malignity. Recorded were the number/type of associated TC (histology/or cytology) and HT (blood/clinic/scintigraphy by {sup *}I dosages). (GB = disease of Graves-Basedow, UFA/MFA = HT by uni- or multifocal functional autonomy, FC = follicular C, PC = papillary C, AC anaplas.C). On 925 TC, the FC has fallen from 64% down to 32%, the TC increased from 25% up to 60%, while the AC and other different C were of stable frequencies. The low frequency of AC has remained stable and it was not associated to HT. The associated HT (n = 97) were UFA in 60% to 13%, MFA (around {+-} 30%) and GB in 10% to 40% of cases. In conclusion, at 70 years since its introduction, the effect of iodide salt remains beneficent. Actually, the epidemiologic evolution described in 1963 by Walthard maintains. Due to the continues slope down of FC and up of PC in Berne during the period 1945 -1996 the general prognostication of TC continues to improve 16 years after the last augmentation of iodine in salt in Switzerland. The general decrease of UFA following the major correction of iodine deficit explains its less frequent association with the TC

    Full Text Available Feline hyperthyroidism (HT is a common endocrine disorder worldwide, but clinical and laboratory features might vary geographically. The aim of this retrospective study was to evaluate feline HT in Japan, and compare results to those of previous study for feline HT. We evaluated 48 feline HT cases clinical and laboratory features. Surprisingly, the youngest patient was 32 months of age (2 year 9 months. There was no significant difference among the study subjects in sex, but frequency of spayed/castrated cats was high (85.4%. Median age was 186 months (32-272 months. 91.3% (n=42 of subjects were over 10 years of age, and 8.7% (n=4 were under 10 years of age. Clinical symptoms included vomiting, 56.3% (n=27; diarrhea, 2.1% (n=1; hyperactivity, 12.5% (n=6; emaciation, 41.7% (n=20; polyuria and polydipsia, 22.9% (n=11; chronic weight loss, 60.4% (n=29; and palpated enlarged thyroid, 2.1% (n=1.

    Supplemental selenium (Se) may affect the clinical course of Graves disease (GD). Evaluate efficacy of add-on Se on medical treatment in GD. Double-blind, placebo-controlled, randomized supplementation trial. Academic endocrine outpatient clinic. Seventy untreated hyperthyroid patients with GD. Additionally to methimazole (MMI), patients received for 24 weeks either sodium selenite 300 µg/d po or placebo. MMI was discontinued at 24 weeks in euthyroid patients. Response rate (week 24), recurrence rate (week 36), and safety. A response was registered in 25 of 31 patients (80%) and in 27 of 33 (82%) at week 24 [odds ratio (OR) 0.93; 95% confidence interval (CI), 0.26 to 3.25; P = 0.904] in the Se (+MMI) and placebo (+MMI) groups, respectively. During a 12-week follow-up, 11 of 23 (48%) and 12 of 27 (44%) relapsed (OR 1.13; 95% CI, 0.29 to 2.66; P = 0.81) in the Se and placebo groups, respectively. Serum concentrations of Se and selenoprotein P were unrelated to response or recurrence rates. At week 36, 12 of 29 (41%) and 15 of 33 (45%) were responders and still in remission in the Se and placebo groups, respectively (OR 0.85; 95% CI, 0.31 to 2.32; P = 0.80). Serum levels of free triiodothyronine/free tetraiodothyronine, thyroid-stimulating hormone receptor antibody, prevalence of moderate to severe Graves orbitopathy, thyroid volume, and MMI starting dose were significantly lower in responders than in nonresponders. A total of 56 and 63 adverse events occurred in the Se and placebo groups, respectively (P = 0.164), whereas only one drug-related side effect (2.9%) was noted in 35 patients on placebo + MMI. Supplemental Se did not affect response or recurrence rates in GD. Copyright © 2017 Endocrine Society

    The gonadal doses following the 131 I treatment of 6 male and 14 female patients with hyperthyroidism were calculated by the method of MIRD, measuring daily radioactivity in the thyroid gland and circulating blood. The testicular dose was 0.52 +- 0.256 rads and the ovarian dose was 0.632 +- 0.488 rads per mCi. In 1965, the genetically significant dose from 131 I treatment of 925 patients with hyperthyroidism was estimated to be 0.0136 mrads/person/year. The genetically significant dose would amount to 0.0613 mrads/person/year, assuming that the total amount of 131 I supplied for treatment in 1965 was administered to treat the hyperthyroid patients with an age-and sex distribution similar to that of the above mentioned group of patients. Sex ratios of the offspring of male and female patients treated with 131 I from 1953 to 1966 were compared with those of offspring born to male and female patients before the treatment. The proportion of males was higher among the offspring of male patients after 131 I treatment than among the offspring of the controls, but the difference was not statistically significant. The sex ratio of the offspring of female patients was not different from that of controls. The mean age of the parents at the times of their children's birth after 131 I treatment was 2.6 - 6.0 year older in male patients and 2.8 - 2.9 year older in female patients than that of controls.

    Graves' ophthalmopathy is characterized by hyperthyroidism, which is associated with higher serum T 3 levels than T 4 due to deiodinase enzymes.The effect of Graves' patient's sera (n=52) with elevated thyroid hormone and TSH receptor or thyroid peroxidase antibody (anti-TPO) levels was investigated on thyroidal, skeletal and eye muscle type 2 deiodinase enzyme (DII) activities. DII activities were measured with 125 I-T 4 substrate, while thyroid hormone and antibody levels with immunoassays.In Graves' ophthalmopathy, sera with elevated FT 4 or FT 3 levels reduced DII activites remarkably in all tissue fractions. Thyroidal DII activities were lower than those using eye muscle fraction (0.6±0.22 vs 1.14±0.43 pmol/mg/min, Pactivities in patients with Graves' ophthalmopathy after methimazole therapy compared to those who had no ophthalmopathy (2.88±2 vs 20.42±11.82 pmol/mg/min, Pactivities, while sera with anti-TPO antibodies were connected to lower DII activities in Graves' ophthalmopathy.In summary, the actions of hyperthyroid sera derived from patients with Graves' disease were tested on tissue-specific DII activities. Elevated FT 4 level-induced DII inactivation is present in Graves' ophthalmopathy, which seems to be also present at the beginning of methimazole therapy. Stimulating TSH receptor antibiodies increased DII activities via their nongenomic effects using sera of hyperthyroid Graves' ophthalmopathy, but anti-TPO antibodies could influence DII activities via altering FT 4 levels. © Georg Thieme Verlag KG Stuttgart · New York.

    A patient with progressively worsening thyrotoxicosis, refractory to medical therapy, is described. Repeated measurements of thyroidal RAI uptake over a 13 month period were low consistently and could not be explained by iodine ingestion, thyroiditis, or administration of exogenous thyroid hormone. An I-131 scan ultimately revealed striking activity at the base of the skull, reflecting ectopic excessive production of thyroid hormone by a solitary functioning metastatic thyroid carcinoma. The thyrotoxic state resolved after large doses of therapeutic I-131. Typical features of this rare cause of hyperthyroidism are discussed

    The aim of this study was to evaluate the fracture resistance of various provisional crown materials using an in vitro model test system. In the present study polycarbonate crowns, prefabricated by the manufacturer (3M Polycarbonate Crown), and the temporary crowns, fabricated in the dental laboratory environment, were fabricated using bis-acryl composite (Protemp II), autopolymerizing PMMA resin (BISICO Temp S), and heat-polymerized PMMA resin (Major C&B-V Dentine). All temporary crowns were stored in distilled water for 24 hours at room temperature prior to testing. The crowns were seated on metal dies, fabricated from Cr-Co alloy (AZ Dental, Konstanz, Germany), and then tested using the indenter of a Hounsfield testing machine (Hounsfield Tensometer, Hounsfield Test Equipment, Raydon, England). The tip of the indenter was located at a position one-third of the way down the inciso-palatine surface at 135 masculine. The data were statistically analyzed for differences using one-way analysis of variance (ANOVA) and the Tukey HSD test (P crowns were significantly different from the BISICO Temp S, Protemp II, and Major C&B-V Dentine (P crowns may be preferable to the other types of temporary crowns used in this study.

    The mechanisms of dyspnea and exercise intolerance have not been fully elucidated. We aimed to investigate the clearance rate of technetium-99m diethyltriaminepentaaceticacid (Tc-99m DTPA) from lungs in hyperthyroid patients without clinical evidence of lung disease and to explore the interactions between their Tc-99m DTPA radioaerosol lung scintigraphy, spirometric measurements, and the levels of thyroid hormones. We studied 19 hyperthyroid patients and 16 sex- and age-matched controls. Thyroid hormone levels were assessed. Spirometric lung function tests, diffusing capacity of the lung for carbon monoxide (DLCO) and the clearance rate of Tc-99m DTPA were performed in all participants. Ratio of DLCO value to the alveolar ventilation (DLCO/VA) and the means of half-time (T 1/2 ) of Tc-99m DTPA clearance rate, which were used to evaluate alveolar-capillary membrane permeability, were calculated. There were no statistical differences between spirometric parameters (vital capacity (VC), force vital capacity (FVC), one second forced expiratory volume (FEV 1 )/FVC, mean forced expiratory flow during the middle of FVC (FEF 25-75)) of the two groups (p>0.05). Although the mean FEV 1 level was significantly lower in the hyperthyroid patients than the control subjects (p 1 was only less than 80 percent of the predicted value. No significant difference in the means of DLCO, DLCO/VA or T 1/2 values of Tc-99m DTPA clearance was observed between the two groups (p>0.05). In hyperthyroid patients, there was a positive relation between DLCO/VA, DLCO/VA% and T 1/2 values of Tc-99m DTPA clearance (p 1/2 values of Tc-99m DTPA clearance in hyperthyroid group (p>0.05). We conclude that increased thyroid hormones have no effect on permeability of alveolar-capillary membrane in hyperthyroid patients. (author)

    Full Text Available Objective: Using radioactive iodine (RAI as the first line therapy for Graves’ hyperthyroidism and as the treatment of choice for relapsed Graves’ disease is increasing in recent times. However, there has been little consensus on the most appropriate dose to use. So this study is to determine the response of hyperthyroidism to fixed doses of 370 MBq and 555 MBq RAI therapies and determine the incidence of hypothyroidism at 6 months post therapy. Methods: Hyperthyroid patients’ case records treated with radioiodine was retrospectively reviewed to determine the response rate of hyperthyroidism to the two fixed dose regimens. Statistical analysis was done with SPSS version 15.0 and the level of statistical significance was taken as p<0.05. Forty subjects, 6 males (15% and 34 females (85% received RAI therapy for Graves’ hyperthyroidism, mean age was 49.4 years (range, 25-75years. The thyroid function status at 6 months post therapy was available for all subjects. 24 patients (60% received 370 MBq while 16 patients (40% received 555 MBq. Results: The response for fixed doses of 370 MBq and 555 MBq were similar (100%. Also, the incidence of hypothyroidism in these subjects which was 66.6% with fixed dose of 370 MBq and 62.5% with fixed dose of 555 MBq within 6 months post RAI therapy were similar. Conclusion: SRAI is highly effective for the treatment of hyperthyroidism, with a cure rate of 100%. However, it has proved impossible to determine a fixed dose regimen for individual patients accurately to guarantee an euthyroid state. This is because hypothyroidism is a natural predictable sequel of RAI therapy.

    Thyrotropin-secreting pituitary adenomas are very rare tumors, known to present overexpression of somatostatin receptor subtype 2 and which may consequently demonstrate abnormal uptake on Ga-DOTA-TOC PET/CT. A 67-year-old woman with a history of operated pituitary macroadenoma presented with symptoms of hyperthyroidism including a large goiter. Her serum thyroid hormone levels were in favor of central hyperthyroidism. Pituitary MRI depicted an empty sella but visualized an ambiguous lesion centered on the left sphenoidal sinus. Complementary Ga-DOTA-TOC PET/CT finally demonstrated intense uptake by the sphenoidal lesion, confirming recurrence of the pituitary adenoma.

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

    Full Text Available Hematological disorders, especially single lineage abnormalities, have been described in hyperthyroidism. Pancytopenia has been reported, without myelodysplastic syndrome or megaloblastic anemia. We studied the peripheral blood smear and the bone marrow aspiration and biopsy of a 65-year-old lady, who presented with pancytopenia and thyrotoxicosis due to multinodular goiter. She denied ingesting any toxic medication. At diagnosis: WBC: 2500 /ul, platelets count: 58.000/ul, hemoglobin level: 6.5 g/dl. The bone marrow was moderately hyper cellular with moderate myelofibrosis and arrested hematopoiesis. The TSH level was: 0.02 mIU/l (N: 0.25-4, the fT3: 18 pmol/l (N: 4-10, the routine serum immunologic tests were negative. After treatment with single agent neomercazole (carbimazole, complete recovery of the blood cell counts was obtained within one month. The bone marrow aspiration, performed three months after starting therapy, showed normal hematopoiesis. The thyroid function tests returned to normal and no autoimmune reaction was detected on routine serum testing. Persistent response was observed six months later under medical treatment. The patient has refused surgical treatment. Reversible myelodysplastic syndrome may also be part of the changes in blood picture of patients with hyperthyroidism, probably due to direct toxic mechanism.

    The influence of dosimetric factors on the outcome of {sup 131}I therapy has been examined in hyperthyroid patients submitted to {sup 131}I treatment. The following factors - which could have influence on the effects of therapy with radioiodine - were analysed: the goitre volume, the thyroid radioiodine uptake after 24 h, and the effective half-life time of {sup 131}I (EHL). Five hundred (500) randomly selected patients with hyperthyroidism, treated with {sup 131}I, were studied. They were divided into three groups (based on clinical examination, hormonal and immunological tests, thyroid scintigraphy and ultrasound imaging). The study shows that the effectiveness of {sup 131}I therapy depends on the thyroid volume and absorbed dose in all the groups of patients and on the thyroid radioiodine uptake and EHL in patients with a single autonomously functioning thyroid nodule. We have failed to determine the borderline D, distinguishing between effective and ineffective therapy. The treatment outcome can be predicted with approximately 70% accuracy, based on minimal absorbed dose

    To determine whether beta-blockade protects rat heart against thyroxine (T4)-induced accelelation of lipid peroxidation, in vivo effects of 3 beta-blockers with different ancillary properties on the mitochondrial oxidative enzyme, antioxidant enzymes and lipid peroxide were investigated. The rats were rendered hyperthyroid by adding T4 to their drinking water for 3 weeks and were treated simultaneously with either carteolol (a blocker with partial agonist activity; 30 mg/kg/day), atenolol (50 mg/kg/day) or arotinolol (a blocker with weak alpha-blocking action; 50 mg/kg/day). The T4-induced tachycardia was alleviated completely by either atenolol or arotinolol, but only partially by carteolol. Cytochrome c oxidase activity in the heart muscle was increased by T4 with a parallel increase in manganese (mitochondrial) superoxide dismutase. Atenolol, but neither carteolol nor arotinolol, suppressed this increase. Similarly, the T4-induced acceleration of lipid peroxidation was suppressed by atenolol alone. Glutathione peroxidase was markedly decreased, and both copper zinc (cytosolic) superoxide dismutase and catalase were also decreased or tended to be decreased by T4. The levels of these 3 enzymes were only minimally affected by the beta-blocker treatments. These results suggest that beta-blockade suppresses mitochondrial hypermetabolism and protects heart muscle against oxidative stress in hyperthyroidism, and that the ancillary properties of beta-blockers such as partial agonist activity and alpha-blocking action negate the protection.

    A retrospective study has been performed in patients treated by iodine-131 for hyperthyroidism between April 1999 and February 2004..Among the 270 patients, 180 were more than 65 years old. After 65 years, hyperthyroidism is most often the consequence of a toxic adenoma or multi-nodular goiter while Graves' disease is most frequent in young patients. Iodine-131 is usually proposed as first line treatment in the elderly, at the opposite of young patients. With a mean follow-up of 12 months, return to euthyroidism is observed in 56.5% of the older patients and in 73.6% of the young patients. We explain this results by the lower incidence of Graves' disease in the elderly. Nuclear medicine physicians are legally obliged to provide patients with a proper information about radioprotection. Recommendations should nevertheless not induce overdue nor illegitimate fear. They should not only be written and standardized, but also given orally and adapted to each patient. Urinary incontinence is not specific to the old patients, but it is more frequent after 65. Collection and storage of contaminated waste is sometimes difficult and has often to be solved on a case by case basis. (author)

    Thyroid hormone entry into cells is facilitated by transmembrane transporters. Mutations of the specific thyroid hormone transporter, MCT8 (Monocarboxylate Transporter 8, SLC16A2) cause an X-linked syndrome of profound neurological impairment and altered thyroid function known as the Allan-Herndon-Dudley syndrome. MCT8 deficiency presumably results in failure of thyroid hormone to reach the neural target cells in adequate amounts to sustain normal brain development. However during the perinatal period the absence of Mct8 in mice induces a state of cerebral cortex hyperthyroidism, indicating increased brain access and/or retention of thyroid hormone. The contribution of other transporters to thyroid hormone metabolism and action, especially in the context of MCT8 deficiency is not clear. We have analyzed the role of the heterodimeric aminoacid transporter Lat2 (Slc7a8), in the presence or absence of Mct8, on thyroid hormone concentrations and on expression of thyroid hormone-dependent cerebral cortex genes. To this end we generated Lat2-/-, and Mct8-/yLat2-/- mice, to compare with wild type and Mct8-/y mice during postnatal development. As described previously the single Mct8 KO neonates had a transient increase of 3,5,3′-triiodothyronine concentration and expression of thyroid hormone target genes in the cerebral cortex. Strikingly the absence of Lat2 in the double Mct8Lat2 KO prevented the effect of Mct8 inactivation in newborns. The Lat2 effect was not observed from postnatal day 5 onwards. On postnatal day 21 the Mct8 KO displayed the typical pattern of thyroid hormone concentrations in plasma, decreased cortex 3,5,3′-triiodothyronine concentration and Hr expression, and concomitant Lat2 inactivation produced little to no modifications. As Lat2 is expressed in neurons and in the choroid plexus, the results support a role for Lat2 in the supply of thyroid hormone to the cerebral cortex during early postnatal development.

    The color vision has been described as one to be very sensitive to the intake of several chemicals. The present research reviews the published literature that is concerned with color vision impairment due to alcohol. Most of this research considers people under long-term effects of alcohol. However, there is little information about temporary effects of alcohol on color vision. A group of ten volunteers aged 18-40 was studied. During the study levels of alcohol in the body were tested with a standard breathalyzer while color vision were studied using Farnsworth Munsell 100 Hue Color Vision Tests. Keywords: Col

    Temporary henna tattoos have become increasingly widespread among children and young people, especially in holiday spots in recent years. Although reactions to henna tattoo are becoming progressively more common, only few cases of a henna pseudo-tattoo resulting in temporary hypertrichosis have been reported so far. Here, we have reported a 5-year-old girl who developed allergic contact dermatitis and localized hypertrichosis on her right arm after application of temporary henna tattoo during summer holiday.

    The onset of fetal thyroid function occurs about 17-18 days after conception in the rat. The maternal hypothyroidism or hyperthyroidism which occur during gestation provokes alteration, the hormonal modification in the newborn rats was analyzed. The hypothyroidism was induced in normal dams, which were being treated for 7 days with methimazole (in the of 0,03 % in drinking water) before mating. The hyperthyroidism was induced in normal dams, which were being treated for 2 days with T{sub 4} (2{mu}g per 100 g body wt/day) before mating. It was seen that the rat which was born from hypothyroid or hyperthyroid dams suffered alteration on its T{sub 4} levels concerning the days 10,20,30 and 60 after birth. The administration of methimazole or thyroxine affects the fetal thyroid gland function, causing alteration of both T{sub 4} levels, even after the birth, indicating that the maternal hypothyroidism or hyperthyroidism influence on the post-natal life of the rat.

    Full Text Available According to modern concepts, the occurrence of complications in utero-placental pool during pregnancy is a common cause of primary placental insufficiency, severe forms of late gestosis, recurrent miscarriage. It is obvious that the study of the nature of violations in the hemostatic system during pregnancy and the development of methods for timely correction will be the prevention of many obstetric diseases. Among the factors that affect hemostasis, thyroid hormones occupy a special place, they are able to influence not only the functional activity of platelets, but also adjust the intensity of the plasma and tissue fibrinolysis. Oppression of fibrinolytic activity is one of the pathogenetic factors of thrombosis development. The aim – to study the efficacy of natural anticoagulant sulodexide in pregnant women with autoimmune hyperthyroidism on the background of hyperhomocysteinemia. Materials and methods. The study involved 34 pregnant women with autoimmune hyperthyroidism complicated by hyperhomocysteinemia. A control group comprised 29 somatically healthy pregnant women. General clinical examination was carried out, the main indicators of all the links of the hemostatic system and the level of homocysteine were determined. Results. We determined that the main group of pregnant is characterized with chronometric and structural hypercoagulation, which manifests itself in the form of subclinical syndrome of disseminated intravascular coagulation, leading to complications of pregnancy, childbirth and the pathological condition of the fetus. Addition of anticoagulant sulodexide to the standard treatment led to the significant change in indices of all the components of hemostasis in pregnant women of the main group, in particular normalization of the total capacity of the coagulation and fibrinolytic systems. Decrease in activity of intravascular coagulation and platelet aggregation, the level of homocysteine was marked. Clinical indicators of

    Full Text Available Graves' disease is the most common form of autoimmune thyroid disorder, characterized by hyperthyroidism due to circulating autoantibodies. To address the pathological features and establish a therapeutic approach of this disease, an animal model carrying the phenotype of Graves' disease (GD in concert with Graves' Ophthalmopathy (GO will be very important. However, there are no ideal animal models that are currently available. The aim of the present study is to establish an animal model of GD and GO disease, and its pathological features were further characterized.A recombinant plasmid pcDNA3.1- T289 was constructed by inserting the TSHR A-subunit gene into the expression vector pcDNA3.1, and genetic immunization was successfully performed by intramuscular injection of the plasmid pcDNA3.1-T289 on female 8-week-old BALB/c mice. Each injection was immediately followed by in vivo electroporation using ECM830 square wave electroporator. Morphological changes of the eyes were examined using 7.0T MRI scanner. Levels of serum T4 and TSHR antibodies (TRAb were assessed by ELISA. The pathological changes of the thyroid and orbital tissues were examined by histological staining such as H&E staining and Alcian blue staining.More than 90% of the immunized mice spontaneously developed goiter, and about 80% of the immunized mice manifested increased serum T4 and TRAb levels, combined with hypertrophy and hyperplasia of thyroid follicles. A significantly increased synthesis of hyaluronic acid was detected in in the immunized mice compared with the control groups.We have successfully established an animal model manifesting Graves' hyperthyroidism and ophthalmopathy, which provides a useful tool for future study of the pathological features and the development of novel therapies of the diseases.

    Radioiodine ( 131 I) therapy has been in use for more than 60 y. Several protocols have been suggested and used for prescribing the activity to be administered to the patients for the treatment of hyperthyroidism; application of these protocols may result in an under or over dose of the hyperthyroid patients. The main objective of this study was to carry out quantitative analysis of the factors responsible for possible under or over dosage of the patients. In this regard, a total of 59 patients [15 diffuse goitre (DG) and 44 nodular goitre (NG) cases] were studied. In order to compare the thyroid doses calculated by using different protocols, the dosimetric approach was followed. 131 I uptakes were measured after 24 and 48 h, respectively, by giving 0.5 MBq of 131 I to each patient. Thyroid mass and effective half-life were also calculated for each patient and the variations in the thyroid doses were analysed. According to the results 28 and 54% patients were under dosed and 72 and 46% patients were over dosed with DG and NG, respectively. The protocols, which have not taken into account the thyroid mass, multi pre-therapeutic 131 I uptakes and the effective half-life of 131 I of the individual patient, showed a higher degree of deviation from the required thyroid dose. Besides these parameters, some fundamental factors such as radiosensitivity, previous exposure to thyroid drugs and duration of the disease are recommended to be incorporated, which can certainly affect the clinical out comes.

    To assess the outcome after 131 I treatment in patients with multinodular (MNG) and nodular toxic goitre (NTG) according to the administered dose and other factors related to the patient, pathology, or previous treatments. A retrospective study was conducted on 108 patients (67 MNG and 41 NTG) treated in our department, with a follow-up period of at least 2 years. Development of hypothyroidism and treatment failure were evaluated along with their relationship with the administered dose and other factors such as age, sex, grade of hyperthyroidism, type of goitre, presence of autoimmunity, or previous antithyroid medication. More than one-third (36.9%) of MNG patients, and even higher proportion of NTG patients (51.2%) developed non-transient hypothyroidism, particularly in those receiving 740MBq (66.7%). No relationship was found with any other variable. The development of early hypothyroidism (before one year) was also not related to any variable. Treatment failure was not related to the dose, but in MNG there was a relationship with male gender, presence of autoimmunity, or previous antithyroid drugs use. The high rate of hypothyroidism obtained with high doses of 131 I in hyperthyroidism secondary to nodular goitre treatment suggests that lower doses might be sufficient to control the disease without an increase in treatment failures. Only patients with positive autoimmunity, in previous anti-thyroid medication, and perhaps male gender in MNG might be given higher doses, as the failure rate increases, but further studies are required.

    We estimate the nutrient budget in a temporary Mediterranean river basin. We use field monitoring and modelling tools to estimate nutrient sources and transfer in both high and low flow conditions. Inverse modelling by the help of PHREEQC model validated the hypothesis of a losing stream during the dry period. Soil and Water Assessment Tool model captured the water quality of the basin. The 'total daily maximum load' approach is used to estimate the nutrient flux status by flow class, indicating that almost 60% of the river network fails to meet nitrogen criteria and 50% phosphate criteria. We recommend that existing well-documented remediation measures such as reforestation of the riparian area or composting of food process biosolids should be implemented to achieve load reduction in close conjunction with social needs.

    2012-01-01

    The purpose of the study was to examine time to reversal of a temporary ostomy, reasons for delayed closure, and patient satisfaction with the scheduling of their closure and related hospital care. Cross-sectional, descriptive study. The target population comprised patients who underwent creation of a temporary ostomy and reversal surgery within one National Health System Hospital Trust in the United Kingdom. The population served by this Trust are ethnically and socioeconomically diverse, predominantly living in urban areas around Greater London. Sixty-one persons who met inclusion criteria were identified. A two-step analytical process was undertaken. First, a literature review examining incidence and causes of delayed stoma closure was undertaken. Second, a postal survey of all patients who had had their stoma closed in 2009 was conducted. Respondents were allowed 2 weeks to complete and return the questionnaire. The survey instrument was developed locally and subjected to content validation using ostomy patients, surgical and nursing colleagues. It consisted of 9 questions querying time from original surgery to closure, reasons for delaying closure surgery beyond 12 weeks, and satisfaction with care. Twenty-seven patients returned their questionnaires, indicating they consented to participate; a response rate of 44%. Half of the respondents (n = 14 [52%]) underwent closure surgery within 6 months of stoma formation; the remaining 48% waited more than 6 months (median: 6.5 months, range: 1.5-26 months). Thirteen patients (48%) reported a delay in receiving their stoma closure; the main reason cited was the need for a course of adjuvant postoperative chemotherapy. Three quarters of respondents (22 [74%]) were satisfied with the overall care they received. Findings from this study suggest that stoma closure may be associated with fewest complications if performed before 12 weeks.

    N.M. Ocarino

    2003-08-01

    Full Text Available The effect of the estrogenic phase in the bone and in the mineral metabolism was studied in Wistar adult female rats kept under euthyroidism or hyperthyroidism for 60 days. The rats were divided, according to the stage of the estrous cycle, into four groups: 1 euthyroid (proestrus-estrus, 2 euthyroid (metaestrus-diestrus, 3 hyperthyroid (proestrus-estrus, and 4 hyperthyroid (metaestrus-diestrus. After 60 days the blood plasma was collected and the concentrations of free T4, estradiol, progesterone, calcium, phosphorus, and of alkaline phosphatase were determined. The bones (femur and tibia were analysed microscopically. Despite of the functional state of the thyroid, the levels of estrogen were significantly higher in the proestrus-estrus. The estrogenic phase increased the plasmatic concentration of calcium significantly in the euthyroid rats but it did not alter the levels of phosphorus and alkaline phosphatase. In the hyperthyroid state no significant differences in the plasmatic concentrations of calcium, phosphorus and alkaline phosphatase throughout the cycle were found. The phases of the cycle did not also influence the bone morphology in the euthyroid and hyperthyroid states. It was concluded that the estrogenic phase increases the plasmatic concentration of calcium, even without altering the bone morphology of the euthyroid rats. In addition the estrogenic phase does not increase the plasmatic calcium and it does not modify the response of the bone as well as of the mineral metabolism under effect of the hyperthyroidism.

    When it is possible that the employee's work ability can be restored through treatment or rehabilitation, disability pension in Finland is granted for a fixed period. We examined which factors are associated with return to work (RTW) after such temporary disability pension. The study included all Finnish residents whose temporary disability pension from the earnings-related pension system started in 2008 (N = 10,269). Competing risks regression analysis was applied to examine register-based determinants for RTW after temporary disability pension due to mental disorders, musculoskeletal diseases, other diseases, and injury over a 4-year follow-up period. The overall cumulative incidence of RTW was 25%. RTW was more probable after temporary disability pension due to injury and musculoskeletal diseases and less probable after temporary disability pension due to mental disorders. Younger age and higher education increased RTW but differences between genders, private and public sector employees, and occupational classes were relatively small. The probability of RTW was higher among those who were employed before their temporary disability pension (subhazard ratio in multivariate analysis 2.41 (95% CI 2.13-2.72) and among the 9% who participated in vocational rehabilitation during their pension [SHR 2.10 (95% CI 1.90-2.31)]. With some exceptions, the results were fairly similar for all diagnostic causes of temporary disability pension. Return to work after temporary disability pension was relatively uncommon. Nevertheless, in all diagnostic groups RTW continued for the whole follow-up period. The low educated and those not employed before temporary disability pension need more support in their RTW. The strong association between vocational rehabilitation and RTW suggests that increasing rehabilitation among those with impaired work ability may promote RTW.

    In this paper, we reviewed the literature on volition and the principal studies on the reasons for choosing temporary work, which explain in more details how voluntary/involuntary status is interpreted. The description of a research, based on a sample of 1979 workers, is presented with two aims: 1. confirm a structural model that examines the effects on satisfaction of some variables, such as motivation and trust; 2. evaluate the influence of volition and reasons for choosing a temporary employment on job satisfaction. The results confirm the plausibility of the proposed structural model and show interesting results regarding the reasons for choosing temporary work.

    Screen-printed sensor for measuring human pulse was designed and first tests using a demonstrator device were conducted. Various materials and sensors' set ups were compared and the results are presented as the starting point for fabrication of fully functional device. As a screen printing substrate, commercially available temporary tattoo paper was used. Using previously developed nanomaterials-based pastes design of a pressure sensor was printed on the paper and attached to the epidermis. Measurements were aimed at determining sensors impedance constant component and its variability due to pressure wave caused by the human pulse. The constant component was ranging from 2kΩ to 6kΩ and the variations of the impedance were ranging from +/-200Ω to +/-2.5kΩ, depending on the materials used and the sensor's configuration. Calculated signal-to-noise ratio was 3.56:1 for the configuration yielding the highest signal level. As the device's net impedance influences the effectiveness of the wireless communication, the results presented allow for proper design of the sensor for future health-monitoring devices.

    Abstract Electrically interfacing the skin for monitoring personal health condition is the basis of skin‐contact electrophysiology. In the clinical practice the use of stiff and bulky pregelled or dry electrodes, in contrast to the soft body tissues, imposes severe restrictions to user comfort and mobility while limiting clinical applications. Here, in this work dry, unperceivable temporary tattoo electrodes are presented. Customized single or multielectrode arrays are readily fabricated by inkjet printing of conducting polymer onto commercial decal transfer paper, which allows for easy transfer on the user's skin. Conformal adhesion to the skin is provided thanks to their ultralow thickness (Tattoo electrode–skin contact impedance is characterized on short‐ (1 h) and long‐term (48 h) and compared with standard pregelled and dry electrodes. The viability in electrophysiology is validated by surface electromyography and electrocardiography recordings on various locations on limbs and face. A novel concept of tattoo as perforable skin‐contact electrode, through which hairs can grow, is demonstrated, thus permitting to envision very long‐term recordings on areas with high hair density. The proposed materials and patterning strategy make this technology amenable for large‐scale production of low‐cost sensing devices. PMID:29593975

    The work in the ESDRED In te grated Project Module 4, Temporary Sealing (using low pH cement) Technology, consisted first of designing a low pH cement formulation and then of preparing several concrete designs suitable for the construction of sealing plugs and for rock support using shot crete techniques. Regarding sealing plugs, a short plug was constructed at Aspo in Sweden and it was very quickly loaded to failure i.e. slippage by applying water pressure to one face. A second, full scale plug was subsequently constructed at Grimsel test site in Switzerland. It was loaded using the swelling pressure created by bentonite blocks which were artificially hydrated. At time of writing the targeted pressure on the plug was not reached. As the saturation of the bentonite is taking longer than expected the partners involved agreed to continue with the saturation of the bentonite blocks and the related data monitoring beyond the ESDRED Project. The studies on low-pH shot crete for rock sup port were based on available recipes of low-pH concrete mixtures for use in a repository. Pilot and full scale tests were carried out in Sweden and in Switzerland. (Author) 5 refs.

    The most important determinant of cellular radiosensivity is the tissue oxygen content at the time of irradiation. The purpose of the present experimental work was to assess a new iscemia-inducing method in order to reduce normal tissue radiation damage during radiotherapy. Temporary ischemia was induced in a cat small intestine by degraded starch microspheres. Regional arterial and tissue blod flow immediately fell by 85% with subsequent normalization within 26 minutes after microsphere injection. No tendency of small vessel thrombosis caused by starch sphere embolization in combination with previous or current intestinal irradiation was detected. Starch sphere remenants were rapidly engulfed by, and persisted within tissue macrophages for 14 days without causing intestinal inflammatory reactions. In vitro studies showed that human platelets neither adhered to nor were aggregated by starch microspheres. The new method, wich occlude arteriolar vessels distal to the mesentric arterial arcades and thus largely excludes collateral blood flow, seems suited to provide effictive and selective feline small intestinal hypoxic radiation protection. This conclusion may also be valid in man

    Stoma formation is commonly performed in operations to treat carcinoma, inflammatory bowel disease (IBD) and familial adenomatous polyposis (FAP). In this study, we report several cases of stomal outlet obstruction and investigate the clinical features of cases of outlet obstruction in patients who underwent diverting loop ileostomy. Sixty-one patients with IBD, FAP or rectal cancer who required diverting loop ileostomy were identified for inclusion in this study. We defined outlet obstruction as a small bowel obstruction at the opening of the ileostomy following surgery. All cases of outlet obstruction were diagnosed by computed tomography. In the univariate analysis the type of diagnosis, type of operation, age, and white blood cell count were the factors significantly associated with outlet obstruction following ileostomy, and outlet obstruction was considered to have a connection with restorative proctocolectomy. In conclusion, we found that adhesion and twisting of the ileostomy were the causes of outlet obstruction. For temporary diversion, simple rotation of the ileostomy should be recommended, especially in restorative proctocolectomy. Additional study is required to explore other risk factors of outlet obstruction.

    Radioiodine (RAI) therapy is a standard procedure in the treatment of hyperthyroidism. However, the use of RAI in euthyroid patients requiring chronic administration of amiodarone (AM) where other antiarrhythmic drugs may lack efficacy is still controversial. The aim of this study was to assess the safety and efficacy of an AM therapy prior to treatment with radioiodine therapy in euthyroid patients with permanent atrial fibrillation (PAF), who had been treated for hyperthyroidism in the past. This was a retrospective observational study. Patients were assessed at baseline and two, six, eight, and 12 months after RAI therapy. 17 euthyroid patients with PAF were qualified to the RAI (female/male 3/14; age range 65 to 87, median 71). The patients required chronic administration of AM as a prophylaxis against sudden death. Each patient received an ablative dose of 800 MBq (22 mCi) of 131I. At baseline and during follow-up, no side effects of the therapy and no signs of drug intolerance were observed. Subclinical hyperthyroidism occurred in two (11.8%) cases after two months of RAI and five weeks of AM administration. In this situation, RAI therapy was repeated. Three patients (17.6%) after six months, and another two (11.8%) after eight months, required an additional dose of 131I due to amiodarone-induced thyrotoxicosis (AIT). Twelve patients (70.6%) returned to spontaneous sinus rhythm within two months. Fourteen patients (82.4%) had sinus rhythm during follow-up after six and 12 months of treatment. Preventive RAI in euthyroid (but previously hyperthyroid) patients with PAF before administration of AM may be the method of choice. This is particularly important for patients who will require permanent AM administration as a life-saving drug.

    Full Text Available Abstract Introduction Resistance to thyroid hormone is a syndrome caused by thyroid hormone receptor β mutations, which are usually inherited in an autosomal-dominant pattern. Case presentation Our patient, a Japanese neonate boy, showed hyperthyroid symptoms at age two days. Although our patient was diagnosed as having resistance to thyroid hormone, his hyperthyroid symptoms continued for two weeks. Therefore, our patient was treated with methimazole and iodine for two weeks from birth, showing no side effects and no symptoms upon treatment. At age 70 days, an R243W mutation in thyroid hormone receptor β was detected in our patient; while absent in his mother, the mutation was present in his father, who never showed any symptoms. Conclusions To the best of our knowledge this is the first case report of a resistance to thyroid hormone in a neonate presenting with hyperthyroid symptoms born to a mother with Graves’ disease and treated with methimazole and iodine. These results suggest that methimazole and iodine may be a good short-term option for treatment.

    Objective: To study the influence of 131 I therapy on the autoimmune status in patients with hyperthyroidism from Graves' disease or Hashimoto thyroiditis. Methods: Thyroid-related hormones and antibodies levels were measured with RIA and IL -2, IL-18 levels were measured with ELISA in 48 hyperthyroid patients (including 41 Graves' disease and 7 Hashimoto thyroiditis) both before and 3-6 months after 131 I treatment as well as in 35 controls. Results: After 131 I therapy, at 3-6 months, 16 of the 48 patients were cured, 17 of the 48 were partially relieved and 15 were rendered hypothyroid. Changes of serum IL-12 and IL-18 were as the follows: (1) Before treatment the serum IL-12 and IL-18 levels were significantly higher in the patients than those in controls (P 0.05). (3) Serum IL-18 levels in all patients after treatment were not significantly different (including those cured, partially relieved or rendered hypothyroid, P>0.05). (4) TGA, TMA percentages in all the patients at anytime were significantly higher than those in controls, but there were no significantly differences among the levels in all the patients. (5) Ser- um IL-12 levels were significantly positively correlated with those of IL-18 and TGA, TMA percentages. Conclusion: 131 I therapy is an effective and safe method to control the hyperthyroid symptoms and it carl also ameliorate the immunological derangement. (authors)

  10. Long-Term Follow-Up of a Child with Autoimmune Thyroiditis and Recurrent Hyperthyroidism in the Absence of TSH Receptor Antibodies

    Full Text Available Hashitoxicosis is an initial, transient, hyperthyroid phase that rarely affects patients with Hashimoto thyroiditis. We present here an unusual case of a child with Hashimoto thyroiditis and recurrent hyperthyroidism. A 4 yr 6/12 old male was diagnosed by us with autoimmune subclinical hypothyroidism (normal free T4, slightly elevated TSH, and elevated TG antibody titer. Two years and 6/12 later he experienced increased appetite and poor weight gain; a laboratory evaluation revealed suppressed TSH, elevated free T4, and normal TSI titer. In addition, an I123 thyroid uptake was borderline-low. A month later, the free T4 had normalized. After remaining asymptomatic for 3 years, the patient presented again with increased appetite, and he was found with low TSH and high free T4. Within the following 3 months, his free T4 and TSH normalized. At his most recent evaluation, his TSH was normal and the free T4 was borderline-high; the TG antibody titer was still elevated and the TSI titer was negative. To our knowledge, this is the first patient reported with Hashimoto thyroiditis and recurrent hyperthyroidism. This case exemplifies the variability of the manifestations and natural history of Hashimoto thyroiditis and supports the need for a long-term evaluation of patients with autoimmune thyroid disease.

    Full text: The first clinical studies concerning treatment of hyperthyroid patients with 131-I date back as far as 1941. However, it was the following years that brought a wide application of these methods. In Podlasie region (north-eastern Poland) radioiodine treatment was first introduced in 1997. Hyperthyroidism in this region affects about 1.5% of population. The number of new patients is about 3,500 per year. Because iodine deficiency is high in this region, toxic nodular goitre rather than Graves' disease tends to be the main cause of hyperthyroidism. The aim of this study was a retrospective analysis of the results of radioiodine treatment of hyperthyroid patients from 1997 to 2003. From 1997 to 2003, 4913 hyperthyroid patients underwent treatment with 131-I (131-I Polatom, Swierk) in the Nuclear Medicine Department of the Medical University of Bialystok. The tested group included: 2106 patients with single solitary nodule, 1968 with multinodular goitre and 839 with Graves' disease. The diagnosis was made on the basis of physical examination and biochemical test results including TSH, fT4 and fT3. All patients had scintigraphic studies with 24 and 48 h uptake of 131-I. They also underwent ultrasound scans to enable assessment of the goitre size and to discover the nodules. All patients with nodules revealed by physical examination and ultrasound scans had biopsy performed under ultrasonographic control. The therapeutic doses of 131-I were calculated on the basis of iodine uptake, goitre size and an assumed absorbed dose. Marinnneli's formula was applied. The assumed absorbed doses were diversified according to the cause of hyperthyroidism and the size of goitre, and ranged from 80 to 350 Gy. In case of small goitres the absorbed doses varied from 80 to 100 Gy. In case of Graves' disease - from 80 to 150 Gy, in solitary nodules from 200 to 350 Gy. 131-I was given to patients orally in capsules. The administered therapeutic doses ranged from 200 mCi to 800 m

    Objective: To study the risk of developing hyperthyroidism in neonates of women with Graves's disease through determination of maternal serum levels of TRAb. Methods: Serum TRAb TSH levels were measured with CLIA and thyroid hormones levels were measured with RIA in 258 pregnant women with Graves' disease (98 week during gstation period) and their neonates (n=259, with a case of twin-baby) (umbilical blood specimen and neonates' venous specimen) as well as once in 30 normal pregnant women as controls. Results: Of the 258 pregnant women, serum TRAb levels were normal (below 1.75 IU/L) in 146 women and the neonates' serum TRAb levels were also normal. Serum TRAb levels were between 1.75∼8.75 IU/L in 109 women and the neonates' serum TRAb levels were somewhat increased but became normal within 15 days. Only three pregnant women had serum TRAb levels above 8.75 IU/L and two of their neonates were frankly hyperthyroid, requiring ATD treatment. Conclusion: Monitoring serum TRAb levels in pregnant women with history of Graves' disease is desirable. Neonates from those with high serum TRAb levels should be examined carefully for possible development of hyperthyroidism. (authors)

    To asses the indications and complications of temporary loop ileostomy. This was a prospective cohort study conducted at Isra University Hospital, Hyderabad, Pakistan between February 2003 and August 2006. All patients who had temporary loop ileostomy during that period were included in this study. The indications and various postoperative complications were noted during postoperative hospital stay and subsequently during follow up till stoma were closed. Fifty six patients fulfilled the selection criteria during the study period. Typhoid (enteric) perforation was the most common indication of loop ileostomy accounting for about two thirds of all cases. Other indications were iatrogenic, covering ileostomy for rectal cancers, following resection anastomosis, tuberculosis, blunt abdominal trauma, anastomosis leak and rectovaginal fistula. Post operative skin excoriation was the most common complication while poor siting, transient edema, retraction and high output were other less common complications. Temporary loop ileostomy is the stoma of choice for temporary faecal diversion as most of its complications are manageable conservatively. (author)

    Purpose: We describe the results of a preliminary prospective study using different recently developed temporary and retrievable inferior vena cava (IVC) filters.Methods: Fifty temporary IVC filters (Guenther, Guenther Tulip, Antheor) were inserted in 47 patients when the required period of protection against pulmonary embolism (PE) was estimated to be less than 2 weeks. The indications were documented deep vein thrombosis (DVT) and temporary contraindications for anticoagulation, a high risk for PE, and PE despite DVT prophylaxis.Results: Filters were removed 1-12 days after placement and nine (18%) had captured thrombi. Complications were one PE during and after removal of a filter, two minor filter migrations, and one IVC thrombosis.Conclusion: Temporary filters are effective in trapping clots and protecting against PE, and the complication rate does not exceed that of permanent filters. They are an alternative when protection from PE is required temporarily, and should be considered in patients with a normal life expectancy.

    Three cats were diagnosed as hyperthyroid based on clinical signs, historical findings, laboratory abnormalities, and basal serum thyroxine (T4) concentrations, and/or nuclear thyroid scans. Additionally, a presumptive diagnosis of thyroid carcinoma with pulmonary metastasis was made in each cat based on radiographic or scintigraphic evaluation. All three cats had solitary pulmonary nodules 1.5 to 2 cm in diameter on survey thoracic radiographs; one cat also had chylous pleural effusion and pulmonary lobar consolidation. Focal pulmonary accumulation of sodium pertechnetate (99mTcO4-) and/or radioiodine (131I) corresponding to radiographic lesions were seen in all cats. Two cats were treated with single ablative doses (1111 to 1480 MBq) of 131I; the remaining cat was euthanatized. One of the treated cats died 8 days later; the other cat was euthanatized 22 weeks following treatment. Histopathologic examination of tissue obtained at necropsy confirmed metastatic thyroid carcinoma in one cat and bronchogenic adenocarcinoma in two cats. Our findings indicate that increased radionuclide uptake in focal pulmonary lesions and cytologic evaluation of tissue obtained by fine-needle aspiration are not specific for thyroid tissue

  2. Iodine Replete among Populations in Nigeria: Is the Population Tending Towards the Development of Iodine Induced Hyperthyroidism (IIH?

    Full Text Available Iodine is a micronutrient which is required for normal thyroid function. The recommended daily intake for iodine is 150 µg, however in pregnant women; higher levels up to 250 µg could be required. Deficiency of iodine in any given population results in iodine deficiency disorder (IDD. Researchers in Nigeria as far back as 1967 had reported the existence of IDD. To combat this public health problem with its associated medical consequences, a policy to ensure salt iodization was enacted. The Nation’s consistent approach to combat IDD was globally recognized and it was adjudged as the only country in Africa that had achieved the goals of sustained elimination of IDD. Although the health benefits derivable from salt iodization seem to outweigh its risk, yet recent epidemiological data are pointing that populations within the country could be tending toward the development of Iodine Induced Hyperthyroidism (IIH, a common disorder associated with salt iodization following chronic iodine deficiency. The need therefore to use evidence based approach to re-examine the County’s iodization policy as well as investigate the impact of salt iodization on thyroid hormone formation, metabolism and associated pathologies becomes very imperative. This could be very helpful in order to prevent the burden of non- communicable disease in a nation already battling with epidemics of various infectious diseases.

    Radioiodine is an effective and safe treatment for hyperthyroidism but has been implicated as a risk factor for deterioration or new presentation of Graves' ophthalmopathy (GO). Prophylactic glucocorticoids appear to prevent this effect. The objective of this study was to document the course of GO after radioiodine therapy. This was a prospective observational study. Patients were assessed at baseline and 2, 4, 6, and 12 months after radioiodine therapy. The study was conducted at a tertiary referral center. Seventy-two GO patients with minimally active eye disease participated in the study. A fixed dose of radioiodine was administered. T(4) was commenced 2 wk later to prevent hypothyroidism. Change in activity and severity of GO were analyzed. Exophthalmometer readings, the width of the palpebral aperture, diplopia scores, and the clinical activity score improved significantly. By clinically significant criteria, the eye disease improved in four patients (transiently in three of the four cases), most likely attributable to the natural course of the disease. No patient's eyes deteriorated. Radioiodine is not associated with deterioration of GO in patients with minimally active eye disease when postradioiodine hypothyroidism is prevented.

    Thermography and pattern classification techniques are used to classify three different pathologies in veterinary images. Thermographic images of both normal and diseased animals were provided by the Long Island Veterinary Specialists (LIVS). The three pathologies are ACL rupture disease, bone cancer, and feline hyperthyroid. The diagnosis of these diseases usually involves radiology and laboratory tests while the method that we propose uses thermographic images and image analysis techniques and is intended for use as a prescreening tool. Images in each category of pathologies are first filtered by Gabor filters and then various features are extracted and used for classification into normal and abnormal classes. Gabor filters are linear filters that can be characterized by the two parameters wavelength λ and orientation θ. With two different wavelength and five different orientations, a total of ten different filters were studied. Different combinations of camera views, filters, feature vectors, normalization methods, and classification methods, produce different tests that were examined and the sensitivity, specificity and success rate for each test were produced. Using the Gabor features alone, sensitivity, specificity, and overall success rates of 85% for each of the pathologies was achieved.

    In a first time, we chose to modify the dose to be administered, on using always the Marinelli formula but on increasing the absorbed dose. In a second time, we wanted to simplify the determination of the dose to be administered by modulating it only in function of the thyroid volume. Two groups of patients were managed for hyperthyroidism recurrence. In a first group the iodine dose ({sup 131}I) was determined with the help of the simplified Marinelli formula: chosen absorbed dose was 150 Gy, gland volume determined by echography, measurement of the fixation at the sixth hour. In the second group, the thyroid volume was determined by echography. The patients with a thyroid from 5 to 30 g received 185 MBq, from 30 to 50 g 370 MBq and superior to 50 g 555 MBq of iodine 131. The two groups of patients have the same characteristics. the results of treatment by iodine 131, evaluated on the dosages of T4L and TSH at three and six months, show the preservation of euthyroidism or the passage in hypothyroidism among 94% of patients in the group 1 and 80% of patients in the group 2. These results are not significantly different. The easiness of the realisation of the treatment in the group 2 lead us to continue this simplified therapy scheme that allows equally to improve the radiation protection of medical personnel by avoiding the use of iodine 131.

  6. Temporary jobs and the severity of workplace accidents.

    From the point of view of workplace safety, it is important to know whether having a temporary job has an effect on the severity of workplace accidents. We present an empirical analysis on the severity of workplace accidents by type of contract. We used microdata collected by the Italian national institute managing the mandatory insurance against work related accidents. We estimated linear models for a measure of the severity of the workplace accident. We controlled for time-invariant fixed effects at worker and firm levels to disentangle the impact of the type of contract from the spurious one induced by unobservables at worker and firm levels. Workers with a temporary contract, if subject to a workplace accident, were more likely to be confronted with severe injuries than permanent workers. When correcting the statistical analysis for injury under-reporting of temporary workers, we found that most of, but not all, the effect is driven by the under-reporting bias. The effect of temporary contracts on the injury severity survived the inclusion of worker and firm fixed effects and the correction for temporary workers' injury under-reporting. This, however, does not exclude the possibility that, within firms, the nature of the work may vary between different categories of workers. For example, temporary workers might be more likely to be assigned dangerous tasks because they might have less bargaining power. The findings will help in designing public policy effective in increasing temporary workers' safety at work and limiting their injury under-reporting. Copyright © 2017. Published by Elsevier Ltd.

    Mass migration is one of the most concerning potential outcomes of global climate change. Recent research into environmentally induced migration suggests that relationship is much more complicated than originally posited by the 'environmental refugee' hypothesis. Climate change is likely to increase migration in some cases and reduce it in others, and these movements will more often be temporary and short term than permanent and long term. However, few large-sample studies have examined the evolution of temporary migration under changing environmental conditions. To address this gap, we measure the extent to which temperature, precipitation, and flooding can predict temporary migration in Matlab, Bangladesh. Our analysis incorporates high-frequency demographic surveillance data, a discrete time event history approach, and a range of sociodemographic and contextual controls. This approach reveals that migration declines immediately after flooding but quickly returns to normal. In contrast, optimal precipitation and high temperatures have sustained positive effects on temporary migration that persist over one to two year periods. Building on previous studies of long-term migration, these results challenge the common assumption that flooding, precipitation extremes and high temperatures will consistently increase temporary migration. Instead, our results are consistent with a livelihoods interpretation of environmental migration in which households draw on a range of strategies to cope with environmental variability.

    Unlike conventional hydrothennal geothermal technology that utilizes hot water as the energy conversion resources tapped from natural hydrothermal reservoir located at {approx}10 km below the ground surface, Enhanced Geothermal System (EGS) must create a hydrothermal reservoir in a hot rock stratum at temperatures {ge}200 C, present in {approx}5 km deep underground by employing hydraulic fracturing. This is the process of initiating and propagating a fracture as well as opening pre-existing fractures in a rock layer. In this operation, a considerable attention is paid to the pre-existing fractures and pressure-generated ones made in the underground foundation during drilling and logging. These fractures in terms of lost circulation zones often cause the wastage of a substantial amount of the circulated water-based drilling fluid or mud. Thus, such lost circulation zones must be plugged by sealing materials, so that the drilling operation can resume and continue. Next, one important consideration is the fact that the sealers must be disintegrated by highly pressured water to reopen the plugged fractures and to promote the propagation of reopened fractures. In response to this need, the objective of this phase I project in FYs 2009-2011 was to develop temporary cementitious fracture sealing materials possessing self-degradable properties generating when {ge} 200 C-heated scalers came in contact with water. At BNL, we formulated two types of non-Portland cementitious systems using inexpensive industrial by-products with pozzolanic properties, such as granulated blast-furnace slag from the steel industries, and fly ashes from coal-combustion power plants. These byproducts were activated by sodium silicate to initiate their pozzolanic reactions, and to create a cemetitious structure. One developed system was sodium silicate alkali-activated slag/Class C fly ash (AASC); the other was sodium silicate alkali-activated slag/Class F fly ash (AASF) as the binder of temper

    This study was to examine the retentive force of crowns to implant abutments with commercial temporary cements. Six different temporary cements were investigated. Cast crowns were cemented to the abutments using each cement and their retentive forces to abutments were determined 7 or 28 days after cementing (n=10). The retentive force of the cements to abutments varied widely among the products [27-109 N (7-day), 18-80 N (28-days)]. The retentive force of all the cements was not reduced as the time elapsed, except for two products tested. The polycarboxylate cements and paste-mixing type eugenol-free cements revealed comparable retentive force after 28 days of storage. The powder-liquid type cements showed a positive correlation (pcement between the retentive force and compressive strength. Mechanical strength of temporary cements could not be a prominent predicting factor for retention of the crowns on the abutments.

    Contact dermatitis following the application of temporary paint-on henna tattoos indicates a potentially serious problem of active sensitization. We describe 2 cases involving sisters who travelled to Bali together and acquired a temporary black henna tattoo to the lower back region. Both sisters subsequently developed a contact dermatitis at the tattoo site, the dermatitis disseminating in one sister. There was persistent hyperpigmentation at the tattoo site in both sisters several months after the application. Patch testing revealed a positive reaction to para-phenylenediamine (PPD) in both sisters. One sister also showed reactions to other hair dyes and to multiple organic dyes. Allergic contact dermatitis to PPD contained in temporary henna tattoos is an increasing problem worldwide, with cross-reaction to related compounds and permanent skin changes, a frequent consequence of sensitization to this significant allergen.

    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

    Full Text Available PITX2 is a homeobox transcription factor involved in embryonic left/right signaling and more recently has been associated to cardiac arrhythmias. Genome wide association studies have pinpointed PITX2 as a major player underlying atrial fibrillation (AF. We have previously described that PITX2 expression is impaired in AF patients. Furthermore, distinct studies demonstrate that Pitx2 insufficiency leads to complex gene regulatory network remodeling, i.e. Wnt>microRNAs, leading to ion channel impairment and thus to arrhythmogenic events in mice. Whereas large body of evidences has been provided in recent years on PITX2 downstream signaling pathways, scarce information is available on upstream pathways influencing PITX2 in the context of AF. Multiple risk factors are associated to the onset of AF, such as e.g. hypertension (HTN, hyperthyroidism (HTD and redox homeostasis impairment. In this study we have analyzed whether HTN, HTD and/or redox homeostasis impact on PITX2 and its downstream signaling pathways. Using rat models for spontaneous HTN (SHR and experimentally-induced HTD we have observed that both cardiovascular risk factors lead to severe Pitx2 downregulation. Interesting HTD, but not SHR, leads to up-regulation of Wnt signaling as well as deregulation of multiple microRNAs and ion channels as previously described in Pitx2 insufficiency models. In addition, redox signaling is impaired in HTD but not SHR, in line with similar findings in atrial-specific Pitx2 deficient mice. In vitro cell culture analyses using gain- and loss-of-function strategies demonstrate that Pitx2, Zfhx3 and Wnt signaling influence redox homeostasis in cardiomyocytes. Thus, redox homeostasis seems to play a pivotal role in this setting, providing a regulatory feedback loop. Overall these data demonstrate that HTD, but not HTN, can impair Pitx2>>Wnt pathway providing thus a molecular link to AF.

    The effects of hyperthyroidism (hyperT/sub 3/), (tri-iodothryonine (T/sub 3/) injected rats), and hypothyroidism (hypoT/sub 3/) (thyroidectomized rats) on the activation of fatty acids by a microsomal long-chain fatty acyl-CoA (LCA-CoA) synthetase and the degradation of LCA-CoA by a microsomal LCA-CoA hydrolase was determined. MAS was assayed by measuring the (1-/sup 14/C)-palmitate or -1-/sup 14/C) oleate incorporated into its water soluble CoA ester. MAH was assayed spectrophotomerically by following the reduction of 5',5'-dithiobis-(2-nitrobenzoic acid) by the CoA released from palmitoyl-CoA or oleoyl-CoA. Enzyme activities are given as mean (nmoles/mg/min) +/- SEM. MAS activities were decreased 36-44% (p < 0.01) in both hypoT/sub 3/ and hyperT/sub 3/ (controls = 101 +/- 4 (n = 11, (1-/sup 14/C)-palmitate) of 72 +/- 2 (n = 5,(1-/sup 14/C)oleate)). These decreases may contribute to the decreased triacelyglycerol (TG) and phospholipid contents in the hyperT/sub 3/ liver and the decreased clearance rate of plasma TG in the hypoT/sub 3/. MAH was decreased 27-42% (p<0.01) only in hypoT/sub 3/ (controls = 77 +/- 3 (n = 11, palmitoyl-CoA) or 45 +/- 1 (n = 5, oleoyl-CoA)). This decrease was corrected by T/sub 3/ treatment. Since the decreased MAH would increase the availability of LCA-CoA, it may contribute to the increased TG synthesis in hypoT/sub 3/.

    Many patients with atrial fibrillation (AF) receive amiodarone. Amiodarone-induced hyperthyroidism (AIH) may develop as a complication. We hypothesized that pulmonary vein (PV) isolation in patients with paroxysmal AF and history of AIH may yield a lower success rate. Among 704 patients who underwent AF ablation in our center between 2007 and 2010, we identified 20 patients (mean age 58.3 ± 5.0 years; 11 males) with paroxysmal AF and overt AIH in the past. The control group consisted of 40 patients with amiodarone-refractory AF and no thyroid dysfunction. All patients underwent circumferential PV isolation. During redo procedures all tachycardias were targeted for ablation. During a 12-month follow-up, in the AIH group 6 (30%) patients were arrhythmia free after a single procedure, in comparison to 25 (62.5%) controls (P = 0.01). Atrial tachycardia (AT) was registered in 7 (35%) AIH patients and in 1 (2.5%) control patient (P = 0.001). AF recurred in 10 (50%) AIH versus 15 (37.5%) control patients (P = 0.2). Redo ablation was performed in 7 (35%) AIH patients and in 3 (7.5%) non-AIH patients (P = 0.01). During a redo procedure a PV-unrelated tachycardia was diagnosed in 5 (25%) AIH patients (vs 0 in the controls, P = 0.003). After the last performed ablation, 12 (60%) AIH patients and 28 (70%) controls had no recurrence, P = 0.56. AIH was an independent predictor of ATs. PV isolation alone has a lower efficacy for preventing recurrence in paroxysmal AF in AIH patients. After repeat ablations, overall freedom from tachyarrhythmias is similar to patients with no history of thyroid dysfunction. © 2013 Wiley Periodicals, Inc.

    Yingliu mixture was developed in 1990s by Affiliated Longhua Hospital of Shanghai University of Traditional Chinese Medicine, for treating diffuse goitre with hyperthyroidism (Graves' disease, GD). Former studies have shown Yingliu mixture combined with methimazole (Y-M) can effectively improve thyroid function and decrease thyrotropin-receptor antibody level. Furthermore, we researched its impact on related cytokines to prove that Y-M improve patients' immunity status. To observe the clinical efficacy of Y-M for treating GD. A total of 120 GD patients were randomly divided into two groups, the treatment and the control groups (n = 60). The treatment group's patients were treated with Y-M. The control group's patients were treated with methimazole alone. Yingliu mixture was orally administered, 25 mL three times daily. Methimazole was administered at 5-25 mg/day. After 12 weeks of the treatment, the cytokines, antibodies related to thyroid function, and Chinese medical syndromes were evaluated. After the treatment, the free triiodothyronine and thyroxine levels in both groups decreased. The thyroid-stimulating hormone level increased in the treatment group. The thyrotropin-receptor antibody levels and TNF-α levels decreased in both groups. In the control group, IL-6 and IFN-γ levels were lower than that before the treatment. In the treatment group, CD4 + and CD25 + levels were higher than pretreatment levels, but IL-10 levels were reduced. the total CMS scores for both groups decreased. The Y-M combination can improve thyroid function, and decrease autoantibodies, cytokines, and clinical symptoms, so its efficacy may surpass that of methimazole alone.

    Soil observations networks at the national scale play an integral role in hydrologic modeling, drought assessment, agricultural decision support, and our ability to understand climate change. Understanding soil moisture variability is necessary to apply these measurements to model calibration, business and consumer applications, or even human health issues. The installation of soil moisture sensors as sparse, national networks is necessitated by limited financial resources. However, this results in the incomplete sampling of the local heterogeneity of soil type, vegetation cover, topography, and the fine spatial distribution of precipitation events. To this end, temporary networks can be installed in the areas surrounding a permanent installation within a sparse network. The temporary networks deployed in this study provide a more representative average at the 3 km and 9 km scales, localized about the permanent gauge. The value of such temporary networks is demonstrated at test sites in Millbrook, New York and Crossville, Tennessee. The capacity of a single U.S. Climate Reference Network (USCRN) sensor set to approximate the average of a temporary network at the 3 km and 9 km scales using a simple linear scaling function is tested. The capacity of a temporary network to provide reliable estimates with diminishing numbers of sensors, the temporal stability of those networks, and ultimately, the relationship of the variability of those networks to soil moisture conditions at the permanent sensor are investigated. In this manner, this work demonstrates the single-season installation of a temporary network as a mechanism to characterize the soil moisture variability at a permanent gauge within a sparse network.

    Recent decades have seen a tremendous increase in the complexity of work arrangements, through job sharing, flexible hours, career breaks, compressed work weeks, shift work, reduced job security, and part-time, contract and temporary work. In this study, we focus on one specific group of workers that arguably most embodies nonstandard employment, namely temporary workers, and examine the consequences of this type of employment on depressive symptoms. This study aims to estimate the effect of being a temporary worker on depressive symptom severity. Accounting for the possibility of mental health selection into temporary work through propensity score analysis, we isolate the direct effects of temporary work on depressive symptoms with varying lags of time since exposure. We use prospective data from the U.S. National Longitudinal Survey of Youth 1979 (NLSY79), which has followed, longitudinally, from 1979 to the present, a nationally representative cohort of American men and women between 14 and 22 years of age in 1979. Three propensity score models were estimated, to capture the effect of different time lags (immediately following exposure, and 2 and 4 years post exposure) between the period of exposure to the outcome. The only significant effects were found among those who had been exposed to temporary work in the two years preceding the outcome measurement. These workers report 1.803 (95% CI 0.552; 3.055) additional depressive symptoms from having experienced this work status (than if they had not been exposed). Moreover, this difference is both statistically and substantively significant, as it represents a 50% increase from the average level of depressive symptoms in this population. PMID:20371142

  19. Temporary sharing prompts unrestrained disclosures that leave lasting negative impressions.

    With the advent of social media, the impressions people make on others are based increasingly on their digital disclosures. However, digital disclosures can come back to haunt, making it challenging for people to manage the impressions they make. In field and online experiments in which participants take, share, and evaluate self-photographs ("selfies"), we show that, paradoxically, these challenges can be exacerbated by temporary-sharing media-technologies that prevent content from being stored permanently. Relative to permanent sharing, temporary sharing affects both whether and what people reveal. Specifically, temporary sharing increases compliance with the request to take a selfie (study 1) and induces greater disclosure risks (i.e., people exhibit greater disinhibition in their selfies, studies 1 and 2). This increased disclosure is driven by reduced privacy concerns (study 2). However, observers' impressions of sharers are insensitive to permanence (i.e., whether the selfie was shared temporarily versus permanently) and are instead driven by the disinhibition exhibited in the selfie (studies 4-7). As a result, induced by the promise of temporary sharing, sharers of uninhibited selfies come across as having worse judgment than those who share relatively discreet selfies (studies 1, 2, and 4-7)-an attributional pattern that is unanticipated by sharers (study 3), that persists days after the selfie has disappeared (study 5), is robust to personal experience with temporary sharing (studies 6A and 6B), and holds even among friends (studies 7A and 7B). Temporary sharing may bring back forgetting, but not without introducing new (self-presentational) challenges. Copyright © 2017 the Author(s). Published by PNAS.

    We report the observation of two patients suffering of vesicular thyroid cancers, immediately metastatic, revealed by second bone injuries of the skull. At the time of diagnosis, these two patients were in clinical and biological hyperthyroidism. This hyperthyroidism continued after complete thyroidectomy, without hormonal substitution and needed the implementation of a treatment by synthetic antithyroid drugs. Every patient received after complete thyroidectomy ablative doses of {sup 131}I. the whole body scintigraphy and conventional imaging enlightened a major extension: big size bone and lungs injuries. Ira-therapy and other therapy lead a partial improvement or a relatively prolonged stabilisation. A moderated biological hypothyroidism was got in the first case after 5.55 GBq of {sup 131}I administration. and in the second case after 3.7 GBq of {sup 131}I administration. Allowing to stop synthesis antithyroid drugs. The death came three years after the diagnosis for the first case and was in relation with a cardiovascular disease. In the second case, the patient died two years after the diagnosis because a hemorrhage on a second injury on the 'falx cerebri'. We emphasize the late diagnosis in these patients; the rarity of the clinic presentation; the very good uptake of {sup 131}I on the second injuries in spite of a reduced TSH, because the very well differentiated character of metastases; unfavourable final evolution. It exists a relative uncertainty about etiology of these persistent hyperthyroidism after complete thyroidectomy in patients with multiple metastases of a differentiated thyroid cancer. Were evoked the presence of antibodies anti receptors of TSH, missing in our two patients and a hormonal hyper-secretion linked to a very important metastases volume, the neoplasms tissue staying well differentiated.

    Iodine deficiency during pregnancy results in thyroid dysfunction and has been associated with adverse obstetric and foetal effects, leading to worldwide salt iodization programmes. As nowadays 69% of the world's population lives in iodine-sufficient regions, we investigated the effects of variation in iodine status on maternal and foetal thyroid (dys)function in an iodine-sufficient population. Urinary iodine, serum TSH, free T4 (FT4) and TPO-antibody levels were determined in early pregnancy (13·3 (1·9) week; mean (SD)) in 1098 women from the population-based Generation R Study. Newborn cord serum TSH and FT4 levels were determined at birth. The median urinary iodine level was 222·5 μg/l, indicating an iodine-sufficient population. 30·8% and 11·5% had urinary iodine levels 500 μg/l, respectively. When comparing mothers with urinary iodine levels 500 vs ≤500 μg/l, there were no differences in the risk of maternal increased or decreased TSH, hypothyroxinaemia or hyperthyroidism. Mothers with urinary iodine levels >500 μg/l had a higher risk of a newborn with decreased cord TSH levels (5·6 ± 1·4 (mean ± SE) vs 2·1 ± 0·5%, P = 0·04), as well as a higher risk of a hyperthyroid newborn (3·1 ± 0·9 vs 0·6 ± 0·3%, P = 0·02). These mothers had newborns with higher cord FT4 levels (21·7 ± 0·3 vs 21·0 ± 0·1 pm, P = 0·04). Maternal urinary iodine levels iodine-sufficient population, higher maternal urinary iodine levels are associated with an increased risk of a hyperthyroid newborn. © 2013 John Wiley & Sons Ltd.

    We present details of four field campaigns carried out on different volcanoes of Kamchatka in 2012-2015. Each campaign was performed in three main steps: (i) installation of the temporary network of seismic stations; (ii) autonomous continuous registration of three component seismic signal; (III) taking off the network and downloading the registered data. During the first campaign started in September 2012, 11 temporary stations were installed over the Avacha group of volcanoes located 30 km north to Petropavlovsk-Kamchatsky in addition to the seven permanent stations operated by the Kamchatkan Branch of the Geophysical Survey (KBGS). Unfortunately, with this temporary network we faced with two obstacles. The first problem was the small amount of local earthquakes, which were detected during operation time. The second problem was an unexpected stop of several stations only 40 days after deployment. Nevertheless, after taking off the network in August 2013, the collected data appeared to be suitable for analysis using ambient noise. The second campaign was conducted in period from August 2013 to August 2014. In framework of the campaign, 21 temporary stations were installed over Gorely volcano, located 70 km south to Petropavlovsk-Kamchatsky. Just in time of the network deployment, Gorely Volcano became very seismically active - every day occurred more than 100 events. Therefore, we obtain very good dataset with information about thousands of local events, which could be used for any type of seismological analysis. The third campaign started in August 2014. Within this campaign, we have installed 19 temporary seismic stations over Tolbachik volcano, located on the south side of the Klyuchevskoy volcano group. In the same time on Tolbachik volcano were installed four temporary stations and several permanent stations operated by the KBGS. All stations were taking off in July 2015. As result, we have collected a large dataset, which is now under preliminary analysis

    Full Text Available Replacement of congenitally missing anterior tooth poses special problems in growing patients. Because an adolescent is typically self- conscious about removing an appliance and revealing a large edentulous space, a removable single tooth partial denture or retainer is an undesirable option. The temporary anchorage devices are invasive and the best recommended for malocclusion that cannot be effectively managed with conventional mechanics. The use of orthodontic miniscrews for interim restorations before the completion of skeletal growth has been used successfully unlike osseointegrated implants lacking the compensatory growth mechanisms of the natural dentition. The following case reports show an esthetic alternative to temporary tooth replacement using miniscrews.

    A temporary demand pacemaker with electrocardiosignal display is introduced in this paper. Double way low-noise electrocardiosignal preamplifier, amplitude limiter, high and low pass filter, 50 Hz notch filter, TTL level generator and stimulating pulse formation circuit are components of the hardware electrocircuit. The demand pacing and the electrocardiosignal display are separately controlled by the software in which the double microcontrollers communications technique is used.

    Full text: Aim of the study: Estimation of the early effects of the treatment of hyperthyroidism with radioactive iodine in correlation with the radioiodine dose, the age at the onset of disease and ultrasonographic (US) findings of the thyroid. Material and methods: Retrospective analysis of the files of 80 patients that underwent a radioactive iodine treatment from the period of 1987 till 2006 because of a diffuse hyperthyroid goiter was performed. The patients were divided in two groups. Group C consisted of patients who were treated with calculated doses from 60-100μC/ml gland volume and group NC who received higher, non-calculated doses. According to age at the onset of disease patients were divided in two groups- group A younger than 40 years and group B older than 40 years. According to the US findings of the thyroid prior to radioiodine therapy patients were divided in two groups group N with predominantly normal US findings and group H with predominantly hypoechoic structure. Results: One year after the application of radioactive iodine 58% of the patients from the group C still remained hyperthyroid, 29% became euthyroid and only 13% developed early hypothyroidism. In the NC group only 7% remained hyperthyroid, 40% were euthyroid, while 54% of the patients developed early hypothyroidism. The occurrence of early hypothyroidism was significantly more frequent in NC than in C group (58% vs. 32%, p<0.05). The age was predictor for the probability of development of early hypothyroidism in C group: only 13% younger in group A, but 46% older patients from group B developed an early hypothyroidism. In the NC group the age was not a predictive factor. In 44 patients there were available records on the US findings prior to radioiodine therapy. In the N group patients that received calculated dose of radioiodine therapy remained euthyroid in 86%, while the patients that received non-calculated dose achieved euthyroidism only in 30%.In the H group there was no

    Amiodarone plays a pivotal role in the treatment of ventricular and supraventricular arrhythmias. However, amiodarone-induced hyperthyroidism (AIH) is one of the most feared complications, which necessitates interdisciplinary treatment and careful balancing of the risks of conservative treatment against those of total thyroidectomy. In this article we discuss the pharmacological aspects of amiodarone and its diverse effects on the thyroid. Furthermore, we present diagnostic and therapeutic strategies and report our positive experiences with total thyroidectomy in patients with AIH. Particularly in patients for whom continuation of amiodarone treatment is compulsory, a well-timed total thyroidectomy is a reliable therapeutic option, with minimal complication rates and immediate amelioration of symptoms.

  11. Temporary Agency Work as a Means of Achieving Flexicurity?

    Directory of Open Access Journals (Sweden)

    Kristina Håkansson

    2012-11-01

    Full Text Available After decades of debate about flexibility, flexicurity has become a new buzzword in working life. Flexicurity refers to both the employer’s demand for flexibility and the employee’s demand for security. Thus, the idea is to solve the flexibility–security trade-off. There is also a discussion that mentions temporary agency work as one way of creating a flexicurity system. The flexibility potential is not called into question—numerical flexibility is a quite common motive for using temporary agency workers. However, the security dimension has to be scrutinized. The aim of this article is to analyze the temporary work agency industry’s potential for providing the security dimensions of the flexicurity model in a Swedish context. The study is based on a survey of whitecollar temporary agency workers in Sweden (n = 533. Overall, the vast majority do not perceive security. Our most important result is that both the work agency and the user firm have a dual impact on the agency workers’ perception of security.

    2007-01-01

    Purpose: Evaluation of the feasibility of implantation and explantation and evaluation of the efficacy of a detachable and retrievable temporary vena cava filter. Materials and Method: The temporary vena cava filter ''OptEase'' (Cordis) is a nitinol filter derived from the ''TrapEase'' (Cordis) permanent filter, which is implantable transjugularly or transfemorally. In contrast to other temporary filters, this type can be detached and is not fixed on a catheter during implantation. Therefore, it is usable as a temporary as well as a permanent filter which can be retrieved up to 12 days after detachment with a special catheter using the loop technique. The ''OptEase'' filter was implanted in 11 patients ranging in age from 19 to 82 (mean age 30 years). In 10 patients the filter was transfemorally implanted and explanted. In 1 patient implantation was performed transjugularly prior to surgery and explantation was performed transfemorally after surgery. All patients had a deep vein thrombosis or iliac vein thrombosis. In 3 patients the filter was implanted prior to surgery. In 2 patients pulmonary embolism was identified. In 5 patients the filter was implanted prophylactically because of deep vein thrombosis according to interdisciplinary diagnosis. Results: No pulmonary embolism occurred during implantation. All filters were able to be retrieved without complications using the loop technique on the 6th, 8th, 12th and 13th day. No captured thrombus material was in the filter. (orig.)

  19. Reducing bias in survival under non-random temporary emigration

    Science.gov (United States)

    Peñaloza, Claudia L.; Kendall, William L.; Langtimm, Catherine Ann

    2014-01-01

    Despite intensive monitoring, temporary emigration from the sampling area can induce bias severe enough for managers to discard life-history parameter estimates toward the terminus of the times series (terminal bias). Under random temporary emigration unbiased parameters can be estimated with CJS models. However, unmodeled Markovian temporary emigration causes bias in parameter estimates and an unobservable state is required to model this type of emigration. The robust design is most flexible when modeling temporary emigration, and partial solutions to mitigate bias have been identified, nonetheless there are conditions were terminal bias prevails. Long-lived species with high adult survival and highly variable non-random temporary emigration present terminal bias in survival estimates, despite being modeled with the robust design and suggested constraints. Because this bias is due to uncertainty about the fate of individuals that are undetected toward the end of the time series, solutions should involve using additional information on survival status or location of these individuals at that time. Using simulation, we evaluated the performance of models that jointly analyze robust design data and an additional source of ancillary data (predictive covariate on temporary emigration, telemetry, dead recovery, or auxiliary resightings) in reducing terminal bias in survival estimates. The auxiliary resighting and predictive covariate models reduced terminal bias the most. Additional telemetry data was effective at reducing terminal bias only when individuals were tracked for a minimum of two years. High adult survival of long-lived species made the joint model with recovery data ineffective at reducing terminal bias because of small-sample bias. The naïve constraint model (last and penultimate temporary emigration parameters made equal), was the least efficient, though still able to reduce terminal bias when compared to an unconstrained model. Joint analysis of several

  2. Industrial production and temporary development after the Emilian Earthquake.

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available The earthquake that on the 20th of May hit Emilia has not been one of the most disastrous in modern Italian history, but it has highlighted the problem of preservation of industrial activities during a reconstruction process. In addition, precisely this system, characterized by great vitality and productivity but also by large seismic vulnerability, was the most affected. Through an analysis of the damages suffered by the industrial facilities, not so much as single buildings but precisely as a system, we want to highlight the challenges imposed by the earthquake: on the one hand, the urgent need to provide for delocalizations and temporary structures to avoid a stop in production in the short­term, and on the other, the re­design and anti­seismic re­planning of productive areas. A proposal was put forward to create temporary zones adjacent to the damaged areas, on which temporary structures should be installed. The latter would allow to limit relocations of medium­long range, which are negative for the territory, and at the same time it would allow the flexibility necessary to re­organize the supply chains. However, in Italy, the management of temporary solutions is seen as a practice too much linked to the emergency and too little to the reconstruction process. The first measures put into place by both the State and the Regions, however, do not seem to show a true understanding of the importance of management and regulations of temporary solutions in the medium­ long term.

    Full Text Available Temporary agency workers are coming under non-standard employments, who have temporary attachment to the working organization. With dynamic business environment and flexible work arrangements, temporary agency employments are also emerged in Sri Lanka. Temporary agency workers are dual committed employees. However, with this dual commitment, organizations face issues in achieving temporary agency workers’ commitment due to low attention of agencies to temporary agency workers. Even though the Client organization provides due attention to temporary agency workers, they fail to receive due commitment due to the lack of attention from agency to temporary agency workers. This study was conducted to identify the agency related factors affecting temporary agency workers’ commitment. This was carried out as a cross sectional field study with a sample of 93 workers from temporary agency works in the ABC (pvt ltd. 93 temporary agency workers were selected as sample. Data were collected via a standard questionnaire that met accepted standards of validity and reliability. Descriptive statistics, Simple ranking, Factor analysis, ANOVA and Independent Sample T-Test technique were performed to analyze data.

    1986-01-01

    Pacific Gas and Electric (PG and E) Company's Diablo Canyon Power Plant (DCPP), which is located on California's central coast, has access to three sources of raw water: creek water, well water, and seawater. Creek and well water are DCPP's primary sources of raw water; however, because their supply is limited, these sources are supplemented with seawater. The purpose of this paper is to discuss the temporary, rental, reverse osmosis systems used by PG and E to process DCPP's raw water into water suitable for plant makeup. This paper addresses the following issues: the selection of reverse osmosis over alternative water processing technologies; the decision to use vendor-operated temporary, rental, reverse osmosis equipment versus permanent PG and E-owned and -operated equipment; the performance of DCPP's rental reverse osmosis systems; and, the lessons learned from DCPP's reverse osmosis system rental experience that might be useful to other plants considering renting similar equipment

    The idea of multiple institutional logics currently draws more and more attention as many organizational actors are forced to operate in ever more complex, temporary and vivid collaborations. We draw on findings from a unique case study of a temporary organization that carried the responsibility...... for the planning and construction of a new super hospital in the capital of Sweden. Our empirical data demonstrates the important role institutional logics contribute with in understanding logics behind actions as well as emerging conflicts in practice throughout the project process. The paper identifies four...... distinct response strategies the project actors relied upon to deal with the multiplicity of logics: total integration, partial decoupling, avoidance, and surfing. We discuss how these response strategies were used, in what situations, and what effects they had on the organization. The paper contributes...

  14. Temporary Life Changes and the Timing of Divorce.

    Fallesen, Peter; Breen, Richard

    2016-10-01

    Marriage is a risky undertaking that people enter with incomplete information about their partner and their future life circumstances. A large literature has shown how new information gained from unforeseen but long-lasting or permanent changes in life circumstances may trigger a divorce. We extend this literature by considering how information gained from a temporary change in life circumstances-in our case, a couple having a child with infantile colic-may affect divorce behavior. Although persistent life changes are known to induce divorce, we argue that a temporary stressful situation allows couples more quickly to discern the quality of their relationship, in some cases leading them to divorce sooner than they otherwise would have. We formalize this argument in a model of Bayesian updating and test it using data from Denmark. We find that the incidence of infantile colic shortens the time to divorce or disruption among couples who would have split up anyway.

    Full Text Available Temporary housing plays an important role in providing secure, hygienic, private, and comfortable shelter in the aftermath of disaster (such as flood, fire, earthquake, etc.. Additionally, temporary housing can also be used as a sustainable form of on-site residences for construction workers. While most of the building components used in temporary housing can be manufactured in a plant, prefabrication technology improves the production efficiency of temporary housing; furthermore, integrated renewable energy systems, for example, solar photovoltaic (PV system, offer benefits for temporary housing operations. In order to assess the environmental impacts of prefabricated temporary housing equipped with renewable energy systems, this study first divides the life cycle of temporary housing into six stages, and then establishes a life cycle assessment (LCA model for each stage. Furthermore, with the aim of reducing the environmental impacts, life cycle carbon reduction measures are proposed for each stage of temporary housing. The proposed methodology is demonstrated using a case study in China. Based on the proposed carbon reduction measures, the LCA of a prefabricated temporary housing case study building equipped with renewable energy systems indicates a carbon emissions intensity of 35.7 kg/m2·per year, as well as a reduction in material embodied emissions of 18%, assembly emissions of 17.5%, and operational emissions of 91.5%. This research proposes a carbon reduction-driven LCA of temporary housing and contributes to promoting sustainable development of prefabricated temporary housing equipped with renewable energy systems.

    We examine the roots of gender segregation in the screening process by using a longitudinal data set of candidates considered for temporary projects at a staffing firm and following their progress through the hiring pipeline. Theories invoked to explain gender segregation across jobs traditionally rely on firm-specific human capital and expectations of future commitment to explain this phenomenon. These do not apply in this setting. Yet we find that the staffing firm is more likely to shortli...

  3. Temporary vs. Permanent Sub-slab Ports: A Comparative ...

    Science.gov (United States)

    Vapor intrusion (VI) is the migration of subsurface vapors, including radon and volatile organic compounds (VOCs), from the subsurface to indoor air. The VI exposure pathway extends from the contaminant source, which can be impacted soil, non-aqueous phase liquid, or contaminated groundwater, to indoor air-exposure points. Therefore, contaminated matrices may include groundwater, soil, soil gas, and indoor air. VOC contaminants of concern typically include halogenated solvents such as trichloroethene, tetrachloroethene, and chloroform, as well as petroleum hydrocarbons, such as the aromatic VOCs benzene, toluene, and xylenes. Radon is a colorless radioactive gas that is released by radioactive decay of radionuclides in rock and soil that migrate into homes through VI in a similar fashion to VOCs. This project focused on the performance of permanent versus temporary sub-slab sampling ports for the determination of VI of halogenated VOCs and radon into an unoccupied house. VOC and radon concentrations measured simultaneously in soil gas using collocated temporary and permanent ports appeared to be independent of the type of port. The variability between collocated temporary and permanent ports was much less than the spatial variability between different locations within a single residential duplex. The agreement of the majority of VOC and radon concentrations, 0–36% relative percent difference, and 2–19% relative standard deviation respectively, of each sub-sl

  4. The Diaspora and Temporary Migrant Workers: Basic Concepts

    Directory of Open Access Journals (Sweden)

    Marija Krstić

    2016-02-01

    Full Text Available The paper looks at the phenomenon of migrant workers who emigrated to Western European countries after World War II. The labor demands created by the economic reconstruction of these countries, most notably Great Britain, West Germany, France, Switzerland, the Benelux countries, Sweden and Austria, coupled with low birth rates and high death rates, made it necessary for them to hire immigrant workers. On the other hand, poor economic conditions, few employment opportunities and a yearning for a higher standard of living drove workers from Italy, Spain, Portugal, Turkey, Yugoslavia, Greece, Ireland, Finland and North Africa to seek work abroad. These temporary migrant workers represent a link between their countries of origin and their host countries, and, as a group of people maintaining links with their native countries, they can also be considered their countries’ diaspora. However, considering the temporary nature of their residence abroad, it is questionable whether they actually are a diaspora. It is for this reason that the paper juxtaposes the phenomena of the diaspora and temporary migrant workers in order to analyze the question of whether, when and how these workers become a diaspora. In particular, it focuses on migrant workers from Yugoslavia, usually referred to as “gastarbajteri” (gastarbeiter, who in the 1960s and 1970s migrated mostly to West Germany, Austria, Australia, France and Switzerland, and on their political treatment by the Yugoslav state.

    The dose absorbed by organs of patients with hyperthyroidism treated with {sup 131} I was estimated by using the MIRDOSE computer program and data from ICRP-53. The calculation were performed using effective half-life and uptake average values, which were determined for 17 patients treated with 370 MBq and 555MBq of {sup 131} I. The results shown that the dose in the thyroid, for a 370 MBq administrated activity, was of 99 Gy and 49.5 Gy for 60 g and 80 g thyroid respectively. The average dose estimated in other organs were relatively low, presenting values lower than 0.1 Gy in the kidneys, bone marrow and ovaries and 0.19 Gy in the stomach.

    The Administrator of the Drug Enforcement Administration is issuing this temporary scheduling order to schedule the synthetic opioids, N-(2-fluorophenyl)-N-(1-phenethylpiperidin-4-yl)propionamide (ortho-fluorofentanyl or 2-fluorofentanyl), N-(1-phenethylpiperidin-4-yl)-N-phenyltetrahydrofuran-2-carboxamide (tetrahydrofuranyl fentanyl), and 2-methoxy-N-(1-phenethylpiperidin-4-yl)-N-phenylacetamide (methoxyacetyl fentanyl), into Schedule I. This action is based on a finding by the Administrator that the placement of ortho-fluorofentanyl, tetrahydrofuranyl fentanyl, and methoxyacetyl fentanyl into Schedule I of the Controlled Substances Act is necessary to avoid an imminent hazard to the public safety. As a result of this order, the regulatory controls and administrative, civil, and criminal sanctions applicable to Schedule I controlled substances will be imposed on persons who handle (manufacture, distribute, reverse distribute, import, export, engage in research, conduct instructional activities or chemical analysis, or possess), or propose to handle, ortho-fluorofentanyl, tetrahydrofuranyl fentanyl, and methoxyacetyl fentanyl.

  9. Permanent Temporariness? Changes in Social Contracts in Knowledge Work

    Directory of Open Access Journals (Sweden)

    Bente Rasmussen

    2012-02-01

    Full Text Available Many sociologists have argued that work no longer plays the central role in contemporary life experience because we have entered an age of insecurity in relation to employment, and knowledge workers are often pictured as egoistical portfolio workers who are only interested in their careers and no longer loyal to their employers. Cappelli (1999 on the other hand argues that more insecure employment relations is a result of employers’ strategy to buy workers rather than offering them long-term relations. Using case studies from seven different knowledge work contexts in Norway, this article argues that more temporary employment relations is not the result of career-seeking portfolio workers, but of changes in employment practices of their employers. These are not primarily changes in the formal employment contracts from permanent to temporary employment, but in the social contracts as they are practiced by the employers and experienced by the knowledge workers in the different contexts of knowledge work. The reason for more temporary relations was not because work does not matter for knowledge workers. On the contrary, we found that they accepted insecure conditions because work mattered and because they were eager to take on new tasks, learn the trade in new fields, and show that they were able to do the job. When they left their employer, it was because they were not able to do a good job in their positions or because they were increasingly directly exposed to an insecure market that signaled that they were not profitable (enough for their employer. Although changes in employment practices by the employers toward more short-term relations are not caused by disloyal portfolio workers, these practices may produce the problem of disloyal workers who have to secure their employment in the labor market.

    1999-01-01

    This article explores the alterations and additions made to houses, colleges, and larger public buildings in their temporary use as convalescent homes for wounded Canadian soldiers during World War I. These ''borrowed buildings'' anticipated and emphasized three important characteristics of subsequent hospital architecture by suggesting that domestic environments enhanced healing, that hospitals should be accessible, and that patients should be segregated according to social status and disease. The broader implications of the study are that temporarily appropriated spaces contribute to the definition of many institutions and often act as arenas of resistance to established practices.

    The aim of this study was to compare the sealing properties of IRM, Coltosol, Cavit G, Adhesor and Clip, which used as temporary filling material in coronal access openings in extracted human primary teeth. Standardized access cavities of 2 x 2 mm were prepared in the eighty-four, caries-free human primary anterior teeth. The teeth were divided randomly into five groups of 16 teeth each. Temporary restorative materials Group A: IRM (Dentsply), Group B: Coltosol (Coltone), Group C: Cavit G (3M), Group D: Adhesor (Spofa Dental) and Group E: Clip (Voco) were applied according to the manufacturer's directions. The specimens were immersed silver nitrate and placed in film developer under fluorescent for 24 hours. The sectioned specimens were evaluated under a digital microscope at x 20 magnifications and blindly scored for microleakage. Clip presented the least microleakage value whereas; Adhesor and IRM presented the higher microleakage values. There were statistically significant differences between Clip and the others groups, while there were no statistically significant differences in microleakage between IRM, Adhesor, Coltosol and Cavit G. However the leakage scores of Clip and Cavit G were congruent (p = 0.454). Amongst the five materials, Clip exhibited a better sealing ability.

    1998-01-01

    Purpose: To evaluate the clot trapping capacity of different temporary vena cava filters in a vena cava model. Methods: A vena cava flow model was built using PVC tubing, a hemodialysis membrane and a pulsatile pump. Blood was imitated by a Dextran 40 solution. Five different temporary vena cava filters and two prototypes were tested using human thrombi. The mechanism of clot capture was observed. Results: Decreasing rank order according to decreasing percentage of clots captured for the 21-mm diameter vena cava model was Cook (C) > Angiocor (A) > Cordis (CD) > Antheor (TF-6) > DIL for thrombi with a diameter of 3 mm and A > C > CD > TF-6 > DIL for 5-mm thrombi. In a cava with diameter of 28 mm, decreasing rank order was C > CD = A > TF-6 > DIL and C > CD = A > DIL > TF-6 for 3- and 5-mm thrombi, respectively. Two new prototypes, the TF-8 and TF-10 filters, achieved better results than the TF-6 filter and were in most conditions comparable to the A and CD filters. In most cases, thrombi were trapped between filter and cava wall. Conclusion: The vena cava flow model demonstrates significant differences in rates of clot capture (range 22%-98%) depending on cava diameter, thrombus size, and filter type

    Full Text Available The current study investigated the effect of temporary inhibition of amygdala in response to metabolic changes caused by stress in female mice. Unilateral and bilateral amygdala cannulation was carried out, and after a week of recovery, 2% lidocaine hydrochloride was injected into the mice amygdalae five minutes before the induction of stress. A communication box was employed to induce stress for four consecutive days and plasma corticosterone, food and water intake, weight changes, and anorexia were measured as stress-induced metabolic changes. Results demonstrated that stress, increases stress, increased plasma corticosterone concentrations, weight, food, and water intake. Temporary inhibition of the amygdala slightly decreased plasma corticosterone concentrations, but did not fully reduce the effect of stress. The bilateral injection of lidocaine hydrochloride to the amygdala reduced the effect of stress and reduced water intake and weight. Unilateral injection of lidocaine hydrochloride into the left and right amygdala reduced food intake. In conclusion, the present study demonstrated that the left side and right side of amygdala nuclei play a different role in metabolic responses in stress.

    2016-12-01

    Full Text Available The increase in the number of atypical work contracts in the field of industry relationships, as part of a major European trend towards gaining more flexibility in the labour market, is significant and cannot be overlooked in most member countries of the European Union. This finding is corroborated by the recent surveys conducted across Europe, that reveal the prevalence of these flexible ways of organizing work, over the archetypal template of the individual work contract. However, this range of atypical contractual arrangements and the great number of versions and subcategories they include, are describing a number of negative features that seem to characterize these new forms of employment. Since the field of atypical employment is complex and we cannot analyse the incidence of these negative effects for all the atypical methods of employment, in the following article we will limit ourselves to explore the pressing issues related to the system of temporary work through work agencies. As we shall see, all aspects of the salary field, of health and safety at work and the level of insecurity and instability of labour through temporary work agency reveals a strong character associated with this kind of precarious employment.

    In many countries, including South Korea, labour market changes have led to an increase in unstable, temporary jobs. There is evidence that workers in such jobs may experience poorer mental health than those in more stable employment. To investigate the association between temporary employment and depressive symptoms in South Korean workers. We analysed data from the 2010-2014 Korean Welfare Panel Study (KOWEPS). Employment type was categorized into workers paid per day of labour (day labourers), those on short-term contracts (fixed-term workers) and permanent workers. The association between employment type and depressive symptoms, measured using the Center for Epidemiological Studies Depression scale (CES-D 11), was examined using the generalized estimating equation model. A total of 3756 workers aged 20-59 were included in the 2010 baseline population. Day labourers had the highest mean CES-D 11 score, followed by fixed-term workers and permanent workers. With the day labourer group as reference, fixed-term workers (β: -1.5027, P < 0.001) and permanent workers (β: -2.1848, P < 0.001) showed statistically significant decreases in depression scores. Compared with day labourers, fixed-term workers and permanent workers had progressively lower depression scores. The findings of this study suggest that mental health inequalities based on employment type exist in South Korea. © The Author 2017.

    Full Text Available A greenhouse study to evaluate adaptation of 4 herbaceous summer legumes to temporary waterlogging was conducted.  Species evaluated were Desmanthus virgatus and Aeschynomene americana in their vegetative stage, and Macroptilium lathyroides and M. atropurpureum in both vegetative and reproductive stages.  The experimental design was randomized blocks with 5 replications and treatments were:  T0, control; T1, saturation by capillary movement placing pots in buckets of 5 L with 10 cm of permanent water; and T2, flooding, placing pots in buckets of 10 L and a layer of water 5 cm above the soil.  The duration of the water treatments was 7 days. Waterlogging did not affect shoot or root biomass production nor nodulation in A. americana, whereas D. virgatus had its highest dry matter production in saturated soil (T1.  In M. lathyroides flooding tolerance was more evident in the reproductive than in the vegetative stage, probably due to more production of adventitious roots and formation of aerenchymatic tissue.  Macroptilium atropurpureum showed adaptation to temporary flooding.  Survival and quick recovery of these species would confirm their potential as forages for temporarily waterlogged soils.Keywords: Forage legumes, flooding, Aeschynomene americana, Desmanthus virgatus, Macroptilium lathyroides, Northeast Argentina.DOI: 10.17138/TGFT(2278-286

    To examine the nature and prevalence of the use of temporary nursing staff in intensive care units and relationships between the use of temporary nursing staff and the occurrence of nosocomial infections (central line-associated blood stream infections and ventilator-associated pneumonia). Hiring temporary nurses raises controversial issues with respect to nurse staffing, care processes and patient outcomes, yet empirical findings regarding the use of temporary nurses are mixed. Whether adverse patient outcomes in intensive care units are related to the use of temporary nursing staff remains unexamined. A retrospective longitudinal design was used. Data were collected monthly from 12 intensive care units at six hospitals; 144 ICU-month data points were used for the analysis. Chi-square, anova and logit regression models were used to examine the research questions. The intensive care units used higher levels of temporary nursing staff, but the use of temporary nursing staff was not significantly associated with nosocomial infections. Nurses' perceptions regarding staffing and resource adequacy were significantly associated with nosocomial infections. No evidence was found to link the use of temporary nursing staff and nosocomial infections. Instead, nurses' perceptions of staffing adequacy were related to nosocomial infections. Given the greater use of temporary nursing staff in intensive care units, nurse managers in intensive care units need to monitor the levels of temporary nurse staffing and develop a systematic approach for hospitals to assist in these nurses' adjustment, which can reduce the burden of both temporary and permanent intensive care unit nurses. In addition to quantitative measures of nurse staffing, nurses' perceptions regarding staffing adequacy can be used to measure nurse staffing in relation to adverse patient outcomes. © 2014 John Wiley & Sons Ltd.

    Statistical inference for capture-recapture studies of open animal populations typically relies on the assumption that all emigration from the studied population is permanent. However, there are many instances in which this assumption is unlikely to be met. We define two general models for the process of temporary emigration, completely random and Markovian. We then consider effects of these two types of temporary emigration on Jolly-Seber (Seber 1982) estimators and on estimators arising from the full-likelihood approach of Kendall et al. (1995) to robust design data. Capture-recapture data arising from Pollock's (1982) robust design provide the basis for obtaining unbiased estimates of demographic parameters in the presence of temporary emigration and for estimating the probability of temporary emigration. We present a likelihood-based approach to dealing with temporary emigration that permits estimation under different models of temporary emigration and yields tests for completely random and Markovian emigration. In addition, we use the relationship between capture probability estimates based on closed and open models under completely random temporary emigration to derive three ad hoc estimators for the probability of temporary emigration, two of which should be especially useful in situations where capture probabilities are heterogeneous among individual animals. Ad hoc and full-likelihood estimators are illustrated for small mammal capture-recapture data sets. We believe that these models and estimators will be useful for testing hypotheses about the process of temporary emigration, for estimating demographic parameters in the presence of temporary emigration, and for estimating probabilities of temporary emigration. These latter estimates are frequently of ecological interest as indicators of animal movement and, in some sampling situations, as direct estimates of breeding probabilities and proportions.

  1. Identification of IGF-I in the calvarial suture of young rats: histochemical analysis of the cranial sagittal sutures in a hyperthyroid rat model.

    Premature closure of cranial sutures has been known as one of the complications of juvenile or congenital hyperthyroidism. Thyroid hormone is an anabolic agent for bone formation in the early stages of childhood development. In children, excess thyroid hormone acts as an acceleration factor for the skeletal bone, whereas in adult hyperthyroidism, it causes bone mineral loss due to the high turnover rate of bone formation and consequently bone resorption. In addition, there are numerous literature descriptions concerning the interactions among bone metabolism, hormones, and growth factors, among which insulin-like growth factor I (IGF-I) is the most abundantly found growth factor in osteoblasts and in bone models in vivo. We therefore investigated whether or not the cranial sutures show accelerated closure and how the local growth factors or cytokines participate and function in local bone metabolism after administration of exogenous excess thyroid hormone in a rat model. A total of 60 female Wistar rats, aged 10 days, were divided into two groups, the triiodothyronine (T3)-treated group (n = 30, T3 0.1 microgram/gm of body weight per day) and the control group (n = 30, saline vehicle only), and were maintained and subsequently sacrificed at 15, 30, and 60 days. The parameters of cranial width derived from the morphologic measurements of the skull indicated that the lambda-asterion distance at 30 days and the pterion-bregma distance at 60 days in the T3-treated group were significantly decreased compared with those of the control group. Furthermore, the fluorescent histologic findings showed fluorescent labeling with no interruption along the suture edges, suggesting continuous bone formation, and displayed narrowing of the suture gap of the sagittal suture in the T3-treated group. Tartrate resistant acid phosphatase staining showed very little osteoclastic activity in the sagittal suture, especially in the T3-treated group. The intensity of immunohistochemical

    Full Text Available Las manifestaciones cardiovasculares del hipertiroidismo son frecuentes, y en ocasiones dominan el cuadro clínico. Con frecuencia, la enfermedad se manifiesta por un estado circulatorio hiperdinámico, con disminución de la resistencia vascular periférica, aumento de la volemia y del volumen minuto cardíaco. La dilatación de las cavidades cardíacas con insuficiencia tricuspídea grave e insuficiencia cardíaca derecha sin hipertensión pulmonar constituye una forma inusual de presentación. Se presenta el caso de una joven paciente, portadora de enfermedad de Graves Basedow, sin antecedentes cardiovasculares, que evoluciona en el transcurso de un mes con edema de miembros inferiores, palpitaciones, diarrea, pérdida de peso y fiebre. Al examen clínico se evidencian taquicardia con pulso irregular, signos de insuficiencia cardíaca derecha acompañado de un intenso soplo regurgitante que aumentaba con la inspiración. Por radiografía de tórax y ecocardiograma se constata cardiomegalia e insuficiencia tricuspídea grave sin hipertensión pulmonar. El cuadro se resuelve en forma rápida luego del tratamiento con propranolol, corticoides y diuréticos, con reversión de la arritmia y franca mejoría de los signos y síntomas. Se analizan en forma breve los efectos de las hormonas tiroideas en el aparato cardiovascular y se postulan probables mecanismos fisiopatológicos de la insuficiencia cardíaca en el hipertiroidismo.Cardiovascular manifestations of hyperthyroidism are frequent and sometimes are relevant in the clinical picture. Usually an hyperdynamic circulatory state hallmarks the disease with low peripheral resistance, increased intravascular volume and cardiac output. However, right chamber dilatation with tricuspid valve regurgitation and cardiac failure are unusual. We present the case of a young woman with Graves-Basedow disease without cardiovascular history who complained about palpitations, peripheral edemas, weight loss and
