PURPOSE The aim of this pilot study was to evaluate the diagnostic value of pleth variability index (PVI) to predict fluid responsiveness in newborn infants during surgery. METHODS PVI was continuously recorded in 29 mechanically ventilated newborn infants during surgery, and episodes of clinically indicated volume expansion (VE) (≥10 ml/kg in ≤15 min)(More)
OBJECTIVE To assess the incidence of complications among a relatively large cohort of fetuses with bronchopulmonary sequestration (BPS) and the success of two different intrauterine treatment modalities. METHODS All cases with a prenatal diagnosis of BPS detected in a 10-year period (2002-2011) in two tertiary referral centers were reviewed(More)
PURPOSE To compare the dose area products of pediatric VCUG in daily practice with the dramatically reduced official German diagnostic reference levels, which are based on selected data. MATERIALS AND METHODS 413 consecutive pediatric VCUG examinations were analyzed. RESULTS The mean dose area product of all examinations was 0.97 dGycm². This is below(More)
Very high concentrations of CA 125 have been found in some ovarian cancer patients after repeated radioimmunodetection with anti-CA 125 antibodies [OC125-F(ab')2]. In one patient we measured a CA 125 concentration of 135,000 kilo-arb. units/L, using an enzyme immunoassay involving OC125 antibodies. With an immunoradiometric assay involving use of two new(More)
BACKGROUND Meconium peritonitis (MP) is a rare prenatal condition that leads to substantial neonatal morbidity and mortality. PATIENTS AND METHODS All patients between 1998 and 2006 referred for prenatal diagnosis were retrospectively analyzed for diagnosis of MP. Prenatal ultrasound findings were compared with postnatal etiology, intraoperative findings,(More)
OBJECTIVE To describe antenatal findings and evaluate prenatal risk parameters for adverse outcome or need for intervention in fetuses with congenital pulmonary airway malformation (CPAM). METHODS In our retrospective study all fetuses with a prenatal diagnosis of CPAM detected in our tertiary referral center between 2002 and 2013 were analyzed.(More)
Identification of the 47,XXX karyotype often occurs adventitiously during prenatal fetal karyotyping in cases of advanced maternal age. Although most females with 47,XXX appear healthy at birth, various types of congenital malformations have been reported, of which urinary tract anomalies are the most frequent. We report on 2 newborns with 47,XXX and(More)
Background Esophageal atresia with or without tracheoesophageal fistula (EA/TEF) represents the most common developmental malformation of the upper digestive tract. It is classified into six subtypes according to the classification of Vogt, depending on anatomical variation of this malformation. Around 50% of the patients with EA/TEF present additional(More)
BACKGROUND Esophageal atresia with/without trachea-esophageal fistula (EA/TEF) denotes a spectrum of severe congenital malformations. The aim of this systematic study was to determine both the recurrence risk for EA/TEF, and the risk for malformations of the VATER/VACTERL association spectrum, in first-degree relatives of patients with isolated EA/TEF.

Morgagni hernia presents a rare type of congenital diaphragmatic hernia (CDH, about 2–5 %) (Herman, J Perinatol 21:343–344, 2001), which is characterized by an anterior mainly right-sided defect of the diaphragm. Infrequently, this is combined with a herniation of the liver into the pericardial cavity (Aké, Prenat Diagn 11:719–724, 1991; Stevens, Pediatr(More)
