The Northwest Regional Screening Program to detect congenital hypothyroidism in infants born in Oregon, Montana, Alaska, and Idaho (combined birthrate of 69,000/ yr) was added to our ongoing screening program in 1975. The program utilizes dried blood filter paper specimens collected routinely in the first few days of life in all four states and again at about 6 weeks of age in Oregon only. The screening test consist of an initial thyroxine (T4) measurement; a thyroid-stimulating hormore (TSH) determination is performed on those specimens with T4 concentrations in the lowest 3% group. Serum samples obtained by venipuncture are requested for confirmation of the diagnosis. In the first two years of the program, 25 infants with primary hypothyroidism were detected amont 110,667 infants screened, a frequency of 1:4,430. Fourteen cases of thyroxine-binding globulin deficiency were also detected, a frequency of 1:7,900. Using the T4 followed by TSH testing approach, the frequency of request for repeat specimens was 0.4% in Oregon and 0.05% in the other states. The cost per specimen was $1.96. The majority of infants lacked clinical signs or symptoms of hypothyroidism; only one infant was clinically suspected of having hypothyroidism prior to detection. The most common neonatal symptoms were constipation, lethargy, and prolonged jaundice, while the most common physical signs were hypotonia, umbilical hernia, and large fontanels. Thyroid scans showed the most common etiology to be thyroid aplasia, followed by an ectopic gland, hypoplasia, and goiter. Serum T4 concentrations were lowest in those infants with aplasia, intermediate in infants with an ectopic gland or hypoplasia, and normal in the infant with the goiter. Neonatal hypothyroidism varies in degree and has several different causes; the capacity to secrete thyroid hormone, the duration before hypothyroidism becomes clinically manifest, and possibly the eventual prognosis for intellectual function depend on the nature of the underlying cause. While the mean age at treatment was 59 days, the goal of diagnosing congenital hypothyroidism and treating affected infants by 1 month of age seems realistic.

We describe a case of thyroid storm due to thyrotoxicosis factitia, which was caused by the ingestion of excessive quantities of exogenous thyroid hormone for the purpose of reducing weight. An 18-year-old female was admitted to the hospital 24 hours after taking up to 50 tablets of synthyroid (1 tablet of synthyroid : levothyroxine 100 microg). Because of her stuporous mental state and acute respiratory failure, she was intubated and treated in the intensive care unit. After reviewing her history carefully and examining plasma thyroid hormone levels, we diagnosed this case as a thyroid storm due to thyrotoxicosis factitia. Her thyroid function test revealed that T3 was 305 ng/dL, T4 was 24.9 microg/dl, FT4 was 7.7 ng/dL, TSH was 0.05 micro IU/mL and TBG was 12.84 microg/mL (normal range: 11.3 - 28.9). TSH receptor antibody, antimicrosomal antibody, and antithyroglobulin antibody were negative. She was recovered by treatment, namely, steroid and propranolol, and was discharged 8 days after admission. Thyroid storm due to thyrotoxicosis factitia caused by the ingestion of excessive thyroid hormone is rarely reported worldwide. Therefore, we now report a case of thyroid storm that resulted from thyrotoxicosis factitia caused by the ingestion of a massive amount of thyroid hormone over a period of 6 months.
