background: practice of interventional cardiology procedures such as coronary angiography (ca) and percutaneous transluminal coronary angioplasty (ptca) has largely increased in recent years and is now changing to a matter of routine in many hospitals. the purpose of this study was to measure skin and organ doses in patients undergoing ca and ptca and to find a probable relation with cardiologi...

In the past, various approaches have been developed to detect adverse effects of pollutants on the thyroid of vertebrates, most of these with special emphasis on the South African clawed frog, Xenopus laevis. Although fish are primarily affected by thyroid-disrupting chemicals, studies into alterations of the thyroid of fish are scarce. Therefore, effects of the reference compound propylthioura...

BACKGROUND Total or near-total thyroidectomy is increasingly used to treat benign thyroid conditions. Lifelong treatment with thyroxine (T4) is then required, but the optimal dose is difficult to predict. This study investigated factors that might predict the ideal T4 dose, with the aim of reducing delays in achieving normal thyroid function after surgery. METHODS Data on 98 patients who unde...

Background: Intensive statin therapy was found to reduce thyroid autoimmunity in women with Hashimoto's thyroiditis. No similar data are available for other hypolipidemic agents. Methods: The participants of the study were 16 women with Hashimoto's thyroiditis and coronary artery disease. On the basis of statin tolerance, they were divided into 2 groups. 8 patients who did not tolerate high-dos...

Objective(s): The aim of this study was to determine whether high-dose radioactive iodine (Na131I) outpatient treatment of patients with thyroid carcinoma is a pragmatically safe approach, particularly for the safety of caregivers. Methods: A total of 79 patients completed the radiation-safety questionnaires prior to receiving high-dose radioactive iodine treatment. The questionnaire studied th...

  Introduction: Radioiodine (131I) is an effective and inexpensive alternative to surgery in the treatment of thyroid hyperfunction. The debate today concerns the maximum and minimum ablative doses, and factors leading to hypothyroidism. Patients & Method: 1035 hyperthyroid patients treated with weight-adjusted ablative doses of 131I were retrospectively assessed for ...

We report a 50-year-old female who suffered from reversible hypothyroidism accompanied by isolated ACTH deficiency. There were no findings indicating a complication of autoimmune thyroiditis. Replacement of maintenance dose of glucocorticoid not only led to improvement of thyroid function, but also caused a transient decrease in T3 and an increase in reverse T3, suggesting that chronic cortisol...

Background: Induction of radioadaptive responses in cells pretreated with a low dose radiation before exposure to a high dose is well documented by many investigators. The aim of this study is to determine the frequency of chromosomal aberration in peripheral blood lymphocytes of patients treated by radioiodine (131I) for hyperthyroidism, with or without previous thyroid scan with 99mTc. Materi...

Background: Sentinel node biopsy (SLNB) is the standard of care for breast cancer treatment and it is getting wide acceptance in Iran. The radiation safety of the procedure has been investigated under controlled conditions, but the standard dose of radiotracer and techniques are not always observed in the community setting. The aim of this study was to assess the magnitude of the absor...

main thyroid disorders are hypothyroidism, hyperthyroidism, all kinds of swellings and tumors. generally, thyroid disorders increase the risk of obesity, heart and vessels disease, anxiety, hair dye, sexual disability and infertility clearly. patients with these diseases have to be aware of appropriate actions for short or long land, air and sea travels in order to prevent side effects of thyro...
