thermal ablation therapies for benign thyroid nodules have been introduced in recent years to avoid the complications of traditional methods such as surgery. despite the little complications and the reportedly acceptable efficacy of thermal ablation methods, quite few medical centers have sought the potential benefits of employing them. this paper provides an introduction to the literature, pri...

discussion thymic cyst must be considered in differential diagnosis of a young child with a cervical mass. introduction ectopic cervical thymic cyst is a very rare cause of neck masses in children. the diagnosis is sometimes very difficult and preoperative, correctly diagnosed thymic cysts in the neck are very low. case presentation we report a 5-year-old boy with a left sided cervical mass and...

Original scientific paper Studies on the evolution of paleo-channels in coastal areas are important for submarine engineering construction and to reveal changes in the global paleoenvironment. Thus, to explore the characteristics of paleo-channels during the late Last Glaciation in the western South Yellow Sea, digital terrain analysis method and ArcGis river extraction function were employed, ...

Introduction: During treatment of breast cancer, Radiotherapy to the Supraclavicular fossa region results in absorption of radiation by the thyroid gland and consequently leads to hypothyroidism in 40% of patients. The aim of this study was to compare thyroid gland radiation absorption during radiotherapy with different anterior-posterior beam radiation of 6-15 and 15-15 MV pho...

A large amount of accurate river cross-section data is indispensable for predicting river stages. However, the measured river cross-section data are usually sparse in the transverse direction at each cross-section as well as in the longitudinal direction along the river channel. This study presents three algorithms to resample the river cross-section data points in both the transverse and longi...

Introdouction: Mucoepidermoid carcinoma (MEC) is one of the most common salivary gland malignancies. The prevalence of salivary gland tumors varies in different geographic areas. In this report, we evaluated the prevalence of MEC in Iran and compared it with that previously reported in other countries. Materials and methods: The files of oral pathology, Shahid Beheshti University of Medical ...

this paper is a statistical and analytical review of endocrine glands disorders, seen in the department of pathology, tehran university medical school, and is based on approximately 40,000 surgical specimens and 2,500 autopsy cases. of 42,500 combined routine surgical and autopsy cases reviewed, we had 2,556 cases of endocrine disorders of which there: thyroid 1,125 cases, ovary 970, testis 268...

Localization of 99mTc- hexakis-2-methoxyisobutylisonitrile (99mTc-MIBI) by parathyroid adenomas is well known, and this warrants MIBI scan to evaluate suspected parathyroid adenoma in primary hyperparathyroidism. Typically, the radionuclide concentrates in both the thyroid gland and parathyroid adenoma in early images, and later on delayed images washes out slowly from the...

Centrally occurring salivary gland tumors are rare. Because of a considerable overlap between the clinical and histopathological features, this group of tumors often produces a diagnostic difficulty to the clinicians and oral pathologists. Acinic cell carcinoma (ACC) is an unusual, low-grade, malignant salivary gland tumor that represents approximately 2% of the salivary gland tumors with almos...

Introduction: High-dose radioactive iodine therapy in differentiated thyroid cancer (DTC) may adversely affect the salivary gland function. This study is aimed to evaluate the effect of radioactive iodine (RAI) with dose of 100 mCi in DTC patients compared to lower doses of less than 30 mCi in hyperthyroid cases. Methods: Fifty four patients (13 men and 41 women) age: 42.3±14.3 (21-71) years w...
