title: Neonatal thyrotoxicosis.
abstract: Neonatal thyrotoxicosis is a transient hyperthyroidism in infants of mothers with current or previous thyrotoxicosis. The pathogenesis have been accepted to be placental transfer of maternal thyroid stimulating immunoglobulins. Of two siblings from a previous thyrotoxic mother the first had marked symptoms of thyrotoxicosis but during the second pregnancy antithyroid treatment was given to the mother and though the child had high levels of thyroid hormones for 6 weeks it had only minimal symptoms of thyrotoxicosis.
