[Neonatal hypothyroidism screening. 9 years' experience at a peripheral hospital]

Since 1979 in our Hospital 2500 newborns have been screened for C.I. by T4 and, afterwards, by TSH test. One case of C.I. was detected with an apparently higher frequency than in Lombardia and Italy. Even in a peripheral hospital, the screening for C.I. is useful for patients and the society and it has to be extended all over the country.
