The Relationship

Background: Thyroxin plays important role in the metabolism of carbohydrate, protein and cholesterol, and in the process of growth. Iodine deficiency disorder not only can be caused by lack of iodine substance but also another competition factor, which is a pollutant substance which is goitergenic (pesticide). This goitergenic substance interferes hormonogenesis of thyroid causing enlargement of thyroid gland known as goiter.Objective: This study was aimed at examining the relationship between status of pesticide and status of iodine deficiency disorders (urinary iodine excretion) of elementary school children and the difference between them based on level of their endemic in Dairi District.Methods: This was an observational study using a cross-sectional design. Palpation of thyroid gland was made to determine the level of endemic; concentration of blood cholinesterase was determined using tinto meter kit; urinary iodine excretion was analyzed with the ammonium persulfate digestion method. Data was analyzed with chi square and anova.Results: Chi square test indicated that the relationship between the concentration of blood cholinesterase and urinary iodine excretion was significant (p<0.05) with OR 11.1 and the relationship between concentration of cholinesterase and iodine deficiency disorders (palpation) was not significant (p>0.05) with OR 1.3. Anova test, based on endemic, indicated that there was a significant difference between the concentration of blood cholinesterase and urinary iodine excretion (p<0.05).Conclusion: There was significant relationship between status of pesticide (concentration of blood cholinesterase) and status of iodine deficiency disorder based on urinary iodine excretion and there was no significant relationship between concentration of cholinesterase and iodine deficiency disorders based on the result of palpation. There was a difference in the average status of pesticide and iodine deficiency disorders status among the elementary school children based on their endemic.

Immunogenic Hyperthyroidism

Data of 196 patients treated for hyperthyroidism exclusively with antithyroid drugs were analyzed retrospectively concerning the relapse rate within a follow-up period of four years. Patients were subdivided for primary or recurrent disease, and for immunogenic or non-immunogenic hyperthyroidism, respectively. In immunogenic as well as in non-immunogeriic hyperthyroidism, the relapse rate was significantly lower for patients with primary disease (35% and 52%, respectively) compared to those with recurrent hyperthyroidism (82%, p <0.001 and 83%, p <0.001, respectively). In patients with primary disease, clinical, biochemical and scintigraphic parameters were tested with respect to their capability of predicting a relapse. For immunogenic hyperthyroidism the highest relapse rates were observed in young patients and in those with large goitres, whereas for non-immunogenic hyperthyroidism they were highest in old patients, in those with nodular goitres and in those without an increased urinary iodine excretion at the time of diagnosing hyperthyroidism.

Summary Aim: In 214 patients with benign thyroid diseases the time-course of urinary iodine excretion (UIE) was investigated in order to identify changes after radioiodine therapy (RITh). Method: UIE was measured photometrically (cerium-arsenite method) and related to urinary creatinine on the first and last day of the radioiodine test and then three days, seven days, four weeks, and six months after 1311 administration. Results: As compared with the level found immediately before radioiodine therapy, median UIE had almost doubled four weeks after therapy and was still significantly elevated six months after therapy. This increase correlated significantly with the target volume as measured by scintigraphy and sonography. Conclusions: The persistent elevation of UIE for months after RITh is a measure of treatment-induced damage to thyrocytes. Therefore, in view of the unfavourable kinetics of iodine that follow it, RITh should if possible be given via a single-dose regime.

Overt Hyperthyroidism

Global TcTU was determined in 568 patients without any specific thyroid drug intake - 54 with normal thyroid, 274 with goitre and euthyroidism and 240 with thyroid autonomy. 57 patients with autonomy and overt hyperthyroidism were the only group with TcTU values significantly higher than normals. Common to all groups was a large scatter of the TcTU values. In 332, the effects of individual iodine supply were studied by measuring the iodine concentration in spot urine samples. There was a significant inverse correlation between the TcTU values and the urinary iodine excretion in the groups of normal thyroids and of goitres with euthyroidism. In the group with autonomy an effect of iodine supply could only be seen in cases of greatly increased urinary iodine excretion, resulting in very low TcTU values. Out of 20 patients with autonomy and iodine contamination, only 4 showed overt hyperthyroidism. The large scatter of TcTU values in all groups may be explained by the persistent iodine deficiency as well as by the frequent exposure to unknown amounts of iodine in patients with thyroid disease. Therefore, the spontaneous TcTU alone cannot identify a small group of patients with autonomy and high risk of iodine-induced hyperthyroidism, from a very large group of patients with goitre.

Background A survey conducted by the central iodine-deficiency disorders team in Himachal Pradesh, a state in the goiter-endemic belt of India, revealed that 10 of its 12 districts have an endemic prevalence of goiter. The survey was conducted to provide health program managers data to determine whether it would be necessary to initiate intervention measures. Objective To assess the status of urinary iodine excretion and household salt iodization levels after three decades of a complete ban on the sale of noniodized salt in this goiter-endemic state in India as measured by assessment of urinary iodine excretion levels and iodine content of salt at the household level. Methods The guidelines recommended by WHO/UNICEF/ICCIDD for a rapid assessment of salt iodization were adopted. In each of the 12 studied districts, all senior secondary schools were enlisted and one school was selected by using a random sampling procedure. Two hundred fifty children 11 to 18 years of age were included in the study. Urine samples were collected from a minimum of 170 children and analyzed using the wet digestion method. Salt samples were also collected from a minimum of 170 children and analyzed using the spot testing kit. Results All districts had a median urinary iodine excretion level > 200 μg/L and 82% of the families were consuming salt with an iodine content of 15 ppm or higher. Conclusions The results of the present study highlight the successful implementation of the salt iodization program in the state of Himachal Pradesh. This positive impact may be due to the comprehensive strategy adopted by the state government to improve the quality of salt, development of an effective monitoring information system and effective information, education, and communication activities.

Legislative Measures

It is well established that iodine supplementation is effective in correcting iodine deficiency and reducing goiter prevalence. In Italy, legislation has allowed the production of iodized salt since 1972, but its consumption is on a voluntary basis. In the present study, the efficacy of legislative measures that made compulsory the availability of iodized salt in foodstores has been evaluated. Urinary iodine excretion and thyroid size, scored according to Pan American Health Organization recommendations, were determined prior to (1981) and 10 years after (1991) the introduction of legislative measures in the whole schoolchildren population residing in a restricted area of the Tuscan Appennines. Moreover, in 1991, thyroid volume was determined by ultrasonography. In 1981, mean urinary iodine excretion was 47.1±22.4 mg/kg creatinine (0.412 μmol/l) and goiter prevalence was 60%, indicating a moderate iodine deficiency. Eighty of the families subsequently used iodized salt on a regular basis; as a result of this excellent compliance, in 1991 the mean urinary iodine excretion increased to 129.7±73 mg/kg creatinine (1.24 μmol/l) and goiter prevalence dropped to 8.1%. The results of this study underline the effectiveness of iodine prophylaxis in correcting iodine deficiency and abating endemic goiter in schoolchildren, and suggest that implementation of measures that make compulsory the availability of iodized salt in foodstores overcomes the fact that there is no law governing the exclusive production and trading of iodized salt.
