BACKGROUND Radioactive iodine 131 ((131)I) therapy has long been used in the treatment of differentiated thyroid cancers (DTC). While salivary and lacrimal glandular complications secondary to (131)I therapy are well documented, there is little in the literature addressing nasolacrimal duct obstruction (NLDO). We aimed to evaluate the frequency of (131)I therapy-acquired NLDO, its correlation t...

among investments in different sections of economy, investment in agriculture is great importance. in addition to increasing production and job opportunities in agriculture, investment in this section will help to increase these in other sections as well, due to back and front relations with other economic activities. due to the fact that investment does not yield rapidly, and it takes some tim...

conclusions: this study provides detailed information and case samples of radiodine contamination artifacts and non-physiological, non-metastatic extra-thyroidal i-131 accumulation in whole-body i-131 imaging. introduction: radioactive iodine has been used for more than 50 years for the treatment of thyroid diseases. differentiated thyroid cancers have the ability to trap iodine. therefore, rad...

The distribution of item generation/time in the performance of elderly on verbal fluency (VF) remains unknown. Objective To analyze the number of items, their distribution and impact of the first quartile on the final test result. Methods 31 individuals performed the tests (average age=74 years; schooling=8.16 years). Results The number of items produced in the first quartile differed fro...

During the 1986 Chornobyl nuclear accident, the then-Soviet republic of Ukraine was hit hard with iodine-131 fallout. Since then, numerous studies have demonstrated a relationship between I-131 exposure from Chornobyl and thyroid cancer risk. Much of the published research, however, has relied on grouped radiation dose estimates rather than individual estimates of radiation exposure. Now a new ...

Figure 1. Salivary gland scintigraphy performed before (March 2005) and after (August 2005) iodine-131 internal radiation therapy (I-131 IRT). Anterior images obtained at 10 and 20 minutes after intravenous injection of Tc-99m, and at 5 minutes after washout by Vitamin C are shown. Original scintigraphy was performed as a dynamic study with 1 min/frame. Significantly higher accumulation was obs...

Background: Tuberculous meningitis (TBM) is a severe form of extra pulmonary tuberculosis with high mortality and morbidity rate in all age group patients specific in adults and children. The incidence and prevalence are not exactly known in Iran. In this study, we tried to evaluate the role of rapid diagnosis and to find out the highest risk group patients.  Methods:Totally,...

PURPOSE The aim of this study was to investigate dental arch dimensions and to classify arch shape in Korean young adults. MATERIALS AND METHODS The sample included 50 Koreans with age ranging from 24 to 32 years. Maxillary and mandibular casts were fabricated using irreversible hydrocolloid and type III dental stones. Incisor-canine distance, incisor-1st molar distance, incisor-2nd molar dis...
