Abstract
Objective: The objective of this study was to determine the incidence of congenital hypothyroidism (CH) in neonates by measuring umbilical cord thyroid stimulating hormone (TSH), born in a Teaching Hospital in Manipur. Materials and Methods: The study was based on the findings from cord blood samples collected from 1,000 babies born to mothers having no systemic (especially thyroid disorders) and obstetrical complications in the last 2 years. Estimation of serum TSH level was carried out by enzyme-linked immunosorbent assay method using Eliscan TM (Diagnova) kit manufactured by Ranbaxy Fine Chemicals Ltd. (RFCL) India in the Department of Physiology, Regional Institute of Medical Sciences, Imphal. Results: The mean, median and standard deviation for the TSH values of the samples were 8.833 mIU/L, 6.824 mIU/L and 7.059 mIU/L respectively. Nearly, 29.3% of the babies had TSH greater than 10 mIU/L. One baby was found to be having CH out of the 1,000 screened. Conclusion: CH represents one of the most common preventable causes of mental retardation. The finding of 1 case of CH out of 1,000 new-borns screened indicates that incidence is high in this state. Screening of all new-borns in the future is highly recommended.
