Goitrous autoimmune thyroiditis in a pediatric population: a longitudinal study.

Background: Patients with autoimmune thyroiditis can present with thyroid function that varies from euthyroidism to frank hypothyroidism or occasionally hyperthyroidism. Although there is a risk of progression from the euthyroid or subclinical hypothyroid state to frank hypothyroidism, the rate of progression is not known.

Objectives: Subjects with diffuse goiter and autoimmune thyroiditis were followed up to observe the rate of deterioration in thyroid function from euthyroid and subclinical hypothyroid states to hypothyroidism.

Prevalence of goitre and autoimmune thyroiditis in schoolchildren in Delhi, India, after two decades of salt iodisation.

Delhi lies in the sub-Himalayan plains and the existence of iodine deficiency is well established. Iodised salt was introduced in Delhi nearly two decades ago. The aim of the present study was to determine the status of iodine nutrition in school-aged children and the prevalence of autoimmune thyroiditis.
