Familial-Related Risks for Congenital Hypothyroidism in Iranian Newborns: A Population-Based Case-Control Study.

Background: Congenital hypothyroidism (CH), as one of the most common endocrine disorders, is a preventable cause of mental retardation.

Objective: This study aimed to identify familial-related risk factors for CH in Iranian newborns.

Methods: A population-based case-control study was performed on the National Registry System of patients with CH in Iran.

A Success Story: Review of the Implementation and Achievements of the National Newborn Screening Program for Congenital Hypothyroidism in Iran.

Context: Today, newborn screening for congenital hypothyroidism (CH) as one of the significant achievements in preventive medicine is integrated into the health systems of many countries worldwide. The national newborn screening for early identification of CH disorder in Iran was established in 2004. The purpose of this study was to review the national newborn screening for CH and its achievements in Iran.

The Impact of Iodine Status on the Recall Rate of the Screening Program for Congenital Hypothyroidism: Findings from Two National Studies in Iran.

Unlabelled: Back ground: Iodine deficiency is one of the important factors in increasing the recall rate in congenital hypothyroidism (CH) screening programs. The present study assessed whether the iodine status of the general population may predict the recall rate or vice versa.

Methods: In the current national study, among 1,382,229 live births delivered between March 2010 and March 2011, 1,288,237 neonates were screened for detecting CH by TSH (thyroid stimulating hormone) measurement via heel prick sampling.
