[Prevalence of XXXX of the thyroid in @entity1 in the Bia  ystok population].

@entity1 @entity1496 @entity5787 @entity66 @entity1669 @entity5651 @entity74 @entity3745
Up-to-date observations in the regions where effective food @entity1496 supplementation was introduced confirm a significant decrease in @entity5651 incidence. However, in some regions the incidence of @entity5651 remains unchanged or even the increase in the frequency of @entity66 of the thyroid like, Grave's-Basedov disease and chronic/subacute @entity1669 is observed. The purpose of the study was to evaluate the prevalence of @entity66 of the thyroid in @entity1 aged 6-13 years in the Polish population after 5 years of obligatory @entity1496 supplementation program. The study included 480 school @entity1 from 4 elementary schools chosen randomly in the city of Bia  ystok and 120 @entity1 at the same age treated due to @entity5651 with KI and/or thyroxin for minimum 12 months in the Regional Specialist Outpatient Clinic of Endocrinology. All @entity1 underwent physical examination with palpation of @entity5651 and USG of the thyroid. @entity1496 concentration was assessed in the morning urine by the catalytic method of Sandell-K  lthoff. The concentrations ofTSH and antibodies against TSH, @entity5787 ( @entity5787 ) and @entity3745 (Tg) were also determined. The mean concentrations of anti-Tg antibodies were statistically significantly higher in @entity1 with @entity5651 in comparison with @entity1 with the thyroid gland within the norm (155.8 IU/ml vs. 24.4 IU/ml, p = 0.045). In @entity1 with @entity5651 the incidence of'positive' titre of anti-Tg antibodies was 4-fold as high as in @entity1 without @entity5651 (33.3% vs. 8.7%, p = 0.0147). High incidence of antibodies against @entity3745 in the population of @entity1 with @entity5651 and a positive correlation between the titre of anti-Tg antibodies and the size of the thyroid in this group suggest a significant role of @entity74 in the pathogenesis of @entity5651 in the studied population.
