    Abstract:
    A study was conducted to determine the thyroid function in a goitre endemia. Sadam is small village in the south district of Sikkim. Severe iodine deficiency exist in this village (prevalence of goitre 73.5%, cretinism prevalence 4%; mean urinary iodine exeretion 4.13 ng/dl - SD 3.1). Total of 72 out pf 142 households were randomly selected. All the inmates of the households above 14 years of age were examined for goitre and blood samples were collected from them for estimation of concentration of thyroid stimulating hormones (triiodothyroine T-3, thyroixe T-4) and thyroid stimulating hormone (TSH). Total of 244 subjects were examined, (137 males and 107 females). Goitre was detected in 149 (61.1%) individuals. The mean T-3, T-4 and TSH concentrations in the non-goitrous groups were (SD in parenthesis) 110.13 ng/dl (26.19), 10.12 ug/dl (2.38) and 1.01 uu/ml (0.52). The corresponding values for the goitrous group were, 132.22 ng/dl (46.25), 9.06 ug/dl (2.04) and 1.33 uu/ml (1.19). The differences in the mean concentrations between the goitrous and non-goitrous groups were statistically significant. An inverse correlation between the goitre size and T-4 on the one hand, and TSH and T-4 on the other hand was noticed. The result of the study show that functional decompensation of the thyroid occur in the majority of goitrous subjects.
