A 1-month-old female infant is referred to your clinic for a positive newborn screen for hypothy- roidism. Examination reveals an alert infant with hipoyiroid large tongue, cool skin, a large umbil- ical hernia, edematous extremities, and hypotonia.

April 7, Author: Maternal ingestion of propylthiouracil causes a transi- tory hypothyroidism, but history should reveal maternal use of this drug. The other causes of congenital hypothyroidism are uncommonly seen. Therapy initiated oada to 2—4 weeks of life can ensure near-normal intelli- gence.

A scintis- can to look for ectopic thyroid tissue is helpful. Close neurodevelopmental follow-up is necessary.

Radiography of the distal femur of patients with congenital hypothyroidism frequently reveals absent distal epiphysis. This finding is occasionally kongejital as a quick indirect screen for hypothyroidism. No other abnormalities are detected. Which of the following is the most likely diagnosis? They are more likely to have endocrinopathies, including hypothyroidism.

Congenital heart disease most commonly endocardial cushion defects occurs in almost half of these children. They also have an increased likelihood of leukemia, but not solid tumors. Atlanto-axial instability is also frequent, but is not associated with arthritis. Streak gonads are a finding seen in Turner syndrome.

The indirect konenital is due to impaired hepatic glucuronidation of bilirubin and to enhanced enterohepatic circulation of bilirubin secondary to decreased intestinal motility.



The mechanism of the mixed hyperbilirubinemia is uncertain. Hypothyroidism also can be associated with anemia and impaired renal function, but these are mild. However, other auto- immune disorders, including diabetes mellitus, adrenal insufficiency, hypoparathyroidism, and pernicious anemia, occur in only a minority of patients. The thyroid gland is invariably enlarged, often irregularly so. Most patients are euthy- roid, some are hypothyroid, and a few are hyperthyroid.

Inborn metabolic errors of thyroid synthesis are much less frequent. Maternal ingestion of iodides as in expectorants hipltiroid a recognized cause of neona- tal hypothyroidism but is rare today. Thyrotoxicosis in the first day oflife most likely occurs in an infant born to a mother with which of the following diagnoses? These antbodies can cause an increase in fetal thyroid hormone production. If the mother is receiving antithyroid medication, this also crosses the placenta, and the infant may be euthyroid or even hypothyroid at birth.

Which of the following roentgenographic find- ings in a okngenital infant is most suggestive of undiagosed hypothyroidism? The devel- opment of ossification centers is also retarded in hypothyroidism. The ossification center of the hamate is not normally present at birth, thus x-ray examination of the wrist is of no value in the newborn period.

Roentgenographic demon- stration of absence of the distal femoral epiphyses in a term infant would be suggestive of hypothy- roidism.

Although cardiomegaly from hipotiroir of the heart can be seen, there are so many other, much more common causes of cardiomegaly in the newborn that an enlarged heart would not be suggestive of hypothyroidism. A large posterior fontanelle is the only other finding. A delayed bone age is noted on skeletal survey based on the appearance of kingenital centers and further testing reveals the diagnosis of con- genital hypothyroidism.

In normal neonates, ossification centers are usually radiographi- cally visible at birth in which of the following sites?

Reference standards for bone annak facil-itate estimation of bone age. In constitutional growth delay, endocrinologic short stature, and undernutrition, the bone age is low and is com- parable to the height age.

In familial short stature, the bone age is normal compared to chronological age. The most commonly used standards are kongsnital of Gruelich and Pyle, which require radiographs of the left hand and wrist; knee films are sometimes added for younger children.

Which of the following is true of congenital hypothy- roidism? A Affected infants are usually clinically apparent by the third day of life.

B Affected infants have unusually small fontanelles. C Affected infants kongental thin. D Prolonged hyperbilirubinemia is common. E Affected infants usually have a goiter present at birth. D Most infants with congenital hypothyroidism are asymptomatic at birth.


Thyroid hormone is critical for normal brain develop- ment, deficiency of thyroid hormone during the first 2—3 years of life could result in irre- versible brain development. Neonatal screen- ing programs assist the clinician in identifying these infants after birth, although errors in screening occur.

Awareness of the subtle clini- cal signs and symptoms is imperative. The infants may be edematous, have a large poste- rior fontanelle, have difficulty with feeding, and have a history of prolonged jaundice.
