[Down's syndrome risk assessment in Denmark--secondary publication].

In 2004 The Danish National Board of Health introduced a new guideline regarding prenatal screening. All pregnant women are now offered a Down's syndrome risk assessment. The new guideline has had an impact on the number of invasive early prenatal procedures.

Transient hyperthyroxinemia in newborns from women with autoimmune thyroid disease and raised levels of thyroid peroxidase antibodies.

Objective: Although it is well established that maternal thyroid disease and increased levels of thyrotropin receptor antibodies (TRab) during pregnancy are associated with a number of complications, is the significance of increased levels of thyroid peroxidase antibodies (TPOab) alone a matter for discussion? The aim of the present study was to examine whether transplacental passage of TPOab from women with autoimmune thyroid disease (AITD) interferes with thyroid function in the neonate.

Methods: Pregnant women with AITD (raised levels of TPOab) and their neonates were monitored with regard to variations of thyroid hormones, thyrotropin (TSH), and TPOab. Pregnant women with non-AITD served as controls.

Incidence of gestational hypertension in gestational diabetes mellitus.

The purpose of this study has been to establish the incidence of gestational hypertension (GH) in women with gestational diabetes mellitus (GDM) and to examine the frequency of complications in women with co-existent GDM and GH. Furthermore, we wished to evaluate the significance of urine albumin excretion determined by the urine albumin creatinine ratio (ACR). A total of 215 successive pregnancies with risk factors for gestational diabetes, as defined by the Danish National Board of Health screened for gestational diabetes by the WHO criteria, were reviewed.
