myotonic dystrophy, also called the Curschmann-Steinert syndrome, is an autosomal dominant inherited neuromuscular disorder characterized by progressive muscular dystrophy, muscle weakness and myotonia, which can affect both mother and child. Complications may arise during pregnancy, delivery, including anaesthetic problems, and in the neonatal period. During pregnancy hydramnion can be a first sign of the disease leading to premature labor and also muscle weakness and myotonia can aggravate complicating the course of delivery. The affected neonate may display severe hypotonia, facial diplegia and respiratory distress. The clinical diagnosis can be confirmed by direct DNA analysis in serum and in chorionvillus biopsy material. In this case report two sisters with myotonic dystrophy are described, their pregnancies, deliveries and the outcome of their affected babies.

This report describes the prenatal findings in monozygotic twins with Costello syndrome. At 16 weeks one twin had 9 mm of nuchal oedema: coarctation of the aorta was diagnosed after birth. At 22(5/7) weeks relative macrocephaly, mild pyelectasia and moderate polyhydramnios were noted in both twins. In the following 4 weeks the polyhydramnios increased significantly without visualisation of filling of the stomach. Between 27(5/7) and 30(2/7) weeks a total of 9 l amniotic fluid was drained and at 30(4/7) weeks prelabor premature rupture of membranes (PPROM) occurred followed by premature labor and delivery. The neonatal period was complicated by growth retardation, deglutition problems, hypotonia, cardiac and respiratory problems. Both twins died on Day 57 because of respiratory insufficiency.
