a retrospective study was undertaken to examine the thyroid cancer cases referred for external radiotherapy to our department during the period of 1991-99. within this period, a total of 33 patients had been treated by irradiation for thyroid cancer or its metastases and these cases were evaluated for age, sex, pathology and type of surgery. the reason of patients’ referral for external radioth...

BACKGROUND The risk of radiation-induced benign and malignant thyroid nodules is well known. OBJECTIVE The aim of this study was to determine the occurrence of thyroid nodules and carcinomas after fractionated total body irradiation (TBI) preceding hematopoietic stem cell transplantation (HSCT) for malignant hematological disease during childhood. METHODS We conducted a retrospective univer...

Objectives: The aim of the study is to determine correlation between thyroid gland elasticity with thyroxine, thyroid-stimulating hormone levels, age, gender and volume in normal population. Methods: was conducted 105 healthy cases. Thyroid evaluated axial plan using ultrasonography. Results: relationship evaluated. mean 11.95 ± 9.23 mm3. A moderate negative found kPa value observed from elasto...

OBJECTIVE Interferon-beta (IFN-β) is widely used in patients with multiple sclerosis (MS), a demyelinating disease of the central nervous system. High incidence of thyroid dysfunction has been reported after administration of IFN-β in MS patients. The aim of this study was to assess the effect of IFN-β1a therapy on simultaneous thyroid and salivary gland function in patients with MS using quant...

Thyroid gland disorders of various types; congenital , infectious, autoimmune, benign and malignant lesions. In the present study we have focused on all the disorders with special reference to age, sex, etiology, etiopathogenesis, complication and pathological diagnostic part of thyroid lesions. This study helps in the detection of thyroid lesions in the early diagnosis, treatment and assessmen...

Objective: The thyroid gland is susceptible to the formation of nodules. Therefore, due to the critical role of selenium in the function of the thyroid gland, the impact of this element on the size and volume of this organ and its nodules were examined. Materials and Methods: During three months, two groups consisting of 30 patients with benign thyroid nodules who were referred to Baghaeipour ...

Background: Due to volatility of radioactive iodine solutions, usually internal exposure would occur in personnel that are working in nuclear medicine centers. The activities in the thyroid of individual s who work in nuclear medicine centers of North West provinces of Iran were measured using NaI (Sodium Iodide) detectors. In every center, nearly 40 - 500 mCi of 131 I and 50 - 600 μ Ci of 125 ...

as well as benign and nialignant neopla.sms develop ill thyroid glands of Irlice and rats in which, for prolonged periods, a state of thyroxine deficiency has been estab lished by any one of the following means : the feeding of a low-iodine diet (1, 2) ; the administration of anti-thyroid substances (5, 15, 25) ; irradiation of the gland by 131J, astatine (211At), or X-rays (7, 12, 14, 19) ; an...

Vocal cords paralysis is not a rare entity and is usually caused by malignant thyroid tomors, and major thyroid & neck surgeries, nontheless it has some unusual and even idiopathic causes as well. This is a report of a case with the primary tuberculosis of thyroid gland which has been confirmed both pathologicaly and microbiologically. The lesion was on the same side of paralysis and had advanc...

PURPOSE To establish a multivariate normal tissue complication probability (NTCP) model for radiation-induced hypothyroidism. METHODS AND MATERIALS The thyroid-stimulating hormone (TSH) level of 105 patients treated with (chemo-) radiation therapy for head-and-neck cancer was prospectively measured during a median follow-up of 2.5 years. Hypothyroidism was defined as elevated serum TSH with d...
