It is necessary to use the iodine containing salt and preparation for disease prevention and control. However, we should not forget or consider the adverse effects of iodine containing salt and preparation in case of overdose. It should know the adverse effects of iodine containing salt and preparation and implement correctly the physician's indication to limit and control these adverse effects

The results of a retrospective study of epidemiological surveys was conducted by National Iodine Deficiency Disorder Control Program and periodic surveys were conducted by the Centre of Preventive Health of An Giang in 1998, 2000 and 2003, showed that the coverage rate of households consumed salt with an iodine concentration of more than 20ppm was 29%, 52.9% and 76.5%, respectively. The median urinary iodine concentration was 1.8mlg/dl, 4.4mg/dl and 5.7mg/dl, respectively. The prevalence of goiter in children age 8-10 years was 20.5%, 12.8% and 6.1%, respectively. In 2003, there were still 71.5% of households situated in the iodine deficiency area in An Giang province. The main reasons make people have not used iodised salt are habit of using normal salt; iodised salt is not available and affordable. Although knowledge about the benefit of iodised salt for preventing endemic goiter is 89.4%, knowledge of using iodised salt for preventing creatinism is low (40%).

This study aims to evaluate CT (Computed Tomography) characteristics through the estimation of HU (Hounsfield Unit) and the corresponding variations using coefficient of variation values for various materials as a function of physical factor. HU values for various materials with varying densities as a function of physical factor were measured using MDCT (Siemens SOMATOM Sensation 4, Germany). The results showed that the HU values were decreased and increased as a function of kVp and material density, respectively. Especially, the HU values for bone and iodine at 140 kVp were 32% and 42% smaller than those at 80 kVp, respectively. In case of iodine, the HU values also decreased and increased as a function of kVp and concentration, respectively. While the HU values were fixed as a function of mAs. The decreased ratio of HU values between 80 keV and 140 keV was different at various concentration and maximum difference was shown as 1.73 at 3% concentration. These results indicated that it may be possible to separate composition of materials, e.g. iodine and bone, using single source CT. The results showed that dual energy techniques using single source CT can be applied to material separation and expand CT imaging techniques to other practical applications.

An clinical examination and quantification of urinary iodine were performed in 1,513 Th¸i people with ages of 6-70 at Chieng Sinh commune Son La province. Results showed that the rate of goiter was 11.76% and at mild level of local goiter and the urinary iodine was at adequate level (more than microgram/dl). However, it should monitor continuously to evaluate timely the iodine deficiency

The efficacy of protein-bound iodine (PBI) determination of the serum as an aid in evaluating thyroid function is presented. The study consists of 85 medical students and staff of the UP-PGH Medical Center who were clinically evaluated as euthyroid. Blood samples were taken and PBI was determined utilizing the procedure by Barker, Humphrey, and Soley. Twenty-four hyperthyroid and nine hypothyroid subjects were evaluated clinically. Basal metabolic rate (BMR) studies were doneThe PBI values obtained ranged from 3.9-9.6 gamma with a mean of 6.87 gamma . No significant difference was found between the student group and the non-student group. The scattergram showed definite elevation of PBI values in hyperthyroidism and lowering in hypothyroidism. A statistically significant difference was observed between hyperthyroid and hypothyroid values. Comparison of PBI and BMR values showed that PBI results were more consistent than BMR in evaluating euthyroidismThe study indicated that PBI determination has a definite use in the evaluation of thyroid function. Some advantages of PBI over BMR as well as extraneous factors influencing PBI are presented in the report

Familial non-medullary thyroid cancer (FNMTC) may be considered as a separate clinical entity with variable aggressive biologic behaviors on the basis of previously published studies. Therefore, a family history of NMTC should be carefully considered as a possible prognostic factor when endocrine surgeons set a plan regarding the extent of surgery, radioactive iodine treatment, and follow-up strategy for FNMTC patients.

There are 2 indicators of national program of iodine deficient disorder control including rate of household used iodine contained salt is 90% and above and level of ioduria of children with ages of 8-10 is 10mcg/dL and above. An investigation was carried out throughout the country. Results: the recovering level of iodine in provinces was significantly increased. The level of ioduria was improved. The morbidity rate of goiter is obviously decreased. The knowledge of women in reproductive ages for effects of iodine was improved. However, the rate of households in 9 provinces of Cöu Long river delta that used iodine contained salt is low (50%
