The systematic screening for congenital hypothyroidism allowed to better precise the transient abnormalities of thyroid function and to interpret their mechanisms and frequency. This study analysed the transient TSH increase observed in 74 children between 1982 and 1987. Eighteen children presented with an obvious disorder, most often iodine intoxication. In 31 cases, iodine poisoning, was likely, according to history. No precise etiology could be found in 25 cases. In 7 children, L-thyroxine treatment was necessary, for various durations.
