Although the New England Regional Screening Program report1 indicates that human error is the most likely cause of failure to detect congenital hypothyroidism in infants, our experience suggests that compensated hypothyroidism might be missed in some newborns unless screening includes a thyroid-stimulating hormone (TSH) assay and a thyroxine (T4) concentration. In the past 2 years, we have diagnosed congenital hypothyroidism in three infants. In at least one of these infants, the disease would not have been identified by T4 concentration screening alone.

Background. A newborn screening program (NSP) for congenital hypothyroidism (CH) was carried out in Guangxi in order to understand the incidence of CH and the factors interrelated to major types of CH in this region of China. Methods. During 2009 to 2013, data from 930 612 newborns attending NSP in Guangxi were collected. Patients were classified with either permanent CH (PCH) or transient CH (TCH) after 2 years of progressive study. Results. A total of 1210 patients were confirmed with CH with an incidence of 1/769, including 68 PCH and 126 TCH cases with incidences of 1/6673 and 1/3385, respectively. The frequency of thyroid stimulating hormone values greater than 5 mIU/L was 7.2%, which, based on WHO guidelines, suggests that the population was mildly iodine deficient. Conclusions. The incidence of CH was high in Guangxi. Approximately two thirds of CH patients were TCH, which may be due to a deficiency in iodine within the population.

Background: Iodine deficiency is associated with goiter and impaired brain function. Neonatal thyroid-stimulating hormone (TSH) screening for congenital hypothyroidism used as an indicator of the degree of iodine deficiency and of its control. An increased frequency of thyroid-stimulating hormone (TSH) measurements above 5 mIU/L in newborn screening corresponds to the impaired iodine status of the population. The aim: to estimate the iodine deficiency and the effectiveness of iodine prophylaxis in Krasnoyarsk territory, Republics of Tuva and Khakassia according the results of neonatal TSH_screening. Methods: An 18-year analysis was performed in 34,980 newborns participating in the national thyroid newborn screening program. The TSH concentration was measured in dry blood spots collected by heel stick on filter paper, 96 hours after birth, using DELFIA method. Results: According to the data of the congenital hypothyroidism screening the rate of TSH < 5 mU/1 was 11.8% in Krasnoyarsk territory (23.9% in 2000) and corresponded to mild iodine deficiency. In different regions of Krasnoyarsk territory the rate of TSH < 5 mU/1 in the newborn varied from 3.5% to 23.7%. The highest values were marked in the Arctic peninsula Taimyr, in cities Zheleznogorsk (nuclear facility) and Sosnovoborsk, in Irbeysky, Suchobuzimsky, Eniseysky, Tuchtetsky, Novoselovsky regions (20.9–23.7%). In the Republic of Khakasia the rate of TSH < 5 mU/1 was 12.5%. In the Republic of Tyva the rate of TSH < 5 mU/1 was – 6.6% (38.6% in 1997; 11.5% in 2000). These results indicate mild iodine deficiency. Conclusion: Our investigations show mild iodine deficiency in Central Siberia demanding continuous adequate iodine prevention. Additional assessment of the iodine intake in the regions with mild iodine deficiency is needed to prevent suboptimal cognitive and psychomotor outcomes.

This report reviews problems encountered during the first five years of operation of the New England Regional Screening Program. Human error was responsible for either overlooked or delayed diagnosis and treatment in 14/159 infants with hypothyroidism. This group consisted of three infants who were never tested, six infants whose diagnosis was missed because of errors during the processing of the blood specimens, and five additional children in whom the diagnosis of hypothyroidism could not be made at birth because the concentrations of thyroid-stimulating hormone were not elevated. Many of the problems, most of which occurred during the first two years of the study, have been eliminated by improved communication and monitoring. This study emphasizes the potential vulnerability of all screening programs and underscores the need for physicians to continue to exercise their best clinical judgement regardless of the circumstances.

AbstractObjectivesPrevalence of Maternal and congenital hypothyroidism is on the rise. To present the thyroid stimulating hormone screening results in babies born to hypothyroid mothers and assess the burden, aetiology of hypothyroidism in these babiesMethodsAll antenatal mothers attending our hospital during the study period were enrolled into the study. Group I includes 249 term babies born to hypothyroid mothers and group II comprises 2154 newborns born to mothers who are euthyroid. Heel prick thyroid stimulating hormone was done for all newborns on day 3 for both groups. Confirmatory venous testing was done for all for babies in group I and screen positives belonging to group II. Evaluation and therapy done as per standard guidelines.ResultsThyroid stimulating hormone values in the two groups are presented. There was significant correlation between peak maternal thyroid stimulating hormone and neonatal day 3 heel prick in group I (r=0.7, P<0.05). The prevalence of positive screening test in groups I and II was 3.8 and 1.03% (p<0.05) whereas corresponding values for confirmed disease was 4.3 and 0.6%, respectively (p<0.05). Aetiological evaluation revealed both transient hypothyroidism (33.3%) and permanent hypothyroidism (66.6%).Conclusion4.3% of babies born to hypothyroid mothers develop congenital hypothyroidism; aetiology being both transient and permanent. A venous test by 3 weeks is helpful in these babies to improve case identification.

To determine the benefit of collecting two routine specimens to test for congenital hypothyroidism, we examined the results of our newborn screening program during the last 9.5 years. The Northwest Regional Screening Program (NWRSP) performs a primary thyroxine test with thyroid-stimulating hormone determinations on the lowest 10% of dried blood filter paper specimens. An initial specimen is obtained in the newborn period, and a routine second specimen is collected at approximately 4 to 6 weeks of age in all infants born in Oregon and 25% of infants born in Idaho, Montana, Alaska, and Nevada. Between May 1975 and October 1984, 182 infants with primary hypothyroidism were detected from 811,917 infants screened, a prevalence rate of 1:4,461. The routine second specimen led to the diagnosis of 19 infants of 484,604 infants screened, a detection rate of 1:25,505. When infants detected by the second screen were compared with those detected by the first screen, they had higher thyroxine and lower thyroidstimulating hormone concentrations on filter paper and serum specimens. When thyroid scanning was used, all but one infant detected by the second screen had some residual thyroid tissue, whereas 35% of infants detected by the first screen had thyroid aplasia. Skeletal maturation was more likely to be normal in infants detected by the second screen. These infants appear to have milder hypothyroidism due to a later age of onset or slower evolution of thyroid failure. At a cost of $31,881 per infant detected by the second screen, the NWRSP found it cost-effective to obtain a routine second specimen.
