Pattern of clinical benign euthyroid goitre in a tertiary care center in the Central Province of Sri Lanka from 1981-2011

Abstract

Objectives To describe the pattern of clinical euthyroidgoitre in a tertiary care unit in Sri Lanka before and after iodination of salt in Sri Lanka. Methods We reviewed our thirty-one year computerised database of patients with goitres, spanning iodination in 1995. Results Prevalence of euthyroid clinical simple diffuse goitre did not reduce during the first thirteen years (p=0.822). However, it reduced in the latter four years from 2008 to 2011. There is significant reduction of prevalence in the younger age groups (p<0.001). A significant reduction of nodular change was observed in all groups within seven years after iodination (p<0.001). Conclusions There was a significant reduction in the prevalence of clinical nodularity in the post-iodination era in all age groups. Reduction in prevalence of clinical euthyroid simple diffuse goitre was observed only during the period 2008-2011.
