Introduction

The screening for hypothyreosis is well established in Hessen concerning tracking, organisation and analysis. There are short comings concerning the follow ups of children with suspicions findings, which shall be overcome by creating a new position. The long-term-follow-up according to the guidelines of the "Arbeitsgemeinschaft Pädiatrische Endokrinologie" is of central interest. Furthermore compliance is improved by regular personal counselling with the parents.

Status and school achievement of 129 children born in Hessen between 1988 and 1992 and notified by a repeatedly elevated concentration of TSH in neonatal screening were evaluated. Interviews of mothers, teachers and pediatricians were used to score the development and educational achievements, respectively. A total of 298,175 newborns were screened and the incidence of permanent congenital hypothyroidism (PCH) was 1: 3,313 (n = 90). The female/male ratio was 1.37:1. In the 69 PCH cases with complete data, athyreosis (52%), hypoplasia (32%), dyshormogenesis (9%) and ectopia (7%) were identified as etiologies. The mean age at start of therapy decreases from day 15 in 1988 to day 9 in 1992; however, 27% of PCH children showed reduced psychomotor development as scored by their pediatrician and 11% attended a special school for educationally subnormal children. Approximately 25% of the children had lower educational achievements irrespective of the school type. Our finding of a relatively high percentage of PCH children with subnormal development points to a failure in disease management. A follow-up program including repeated serum TSH monitoring and yearly examinations by pediatric endocrinologists and supervision by the regional screening center is necessary to ensure the long-term efficacy of neonatal screening for congenital hypothyroidism.

None of the various modalities is superior alone, so that it is often necessary to combine them for diagnostic imaging of pancreatic islet cell tumors.
