Diagnosing developmental dysplasia of the hip using the Graf ultrasound method: risk and protective factor analysis in 11,820 universally screened newborns.

Unlabelled: The essential role of ultrasound examinations in diagnosis and treatment of developmental dysplasia of the hip (DDH) is widely accepted while the weighting and correlation of protective factors and perinatal risk for DDH still give rise to debate. Our aim was to investigate the impact of single and twofold combined risk and protective factors on the newborns' hip maturity, assessed with the Graf ultrasound method. Therefore, data sets of 11,820 universally screened newborns were analyzed.

Transplacental metabolic alkalosis.

We present a newborn with hypochloraemic metabolic alkalosis due to severe metabolic alkalosis of his mother. Hypoventilation as a leading symptom resolved quickly with treatment but may be life-threatening if not detected. In this case, the mother had a probable eating disorder.

An outbreak of rotavirus infections in newborns--new aspects?

In the context of a prospective study for detection of rotavirus infections, an outbreak in neonates was observed in April 1986 at the Schweizerische Pflegerinnenschule in Zurich. Altogether, 103 neonates were investigated by means of genome gel electrophoresis for rotaviruses (HRV, human rotavirus) in the feces in the course of April 1986. Of these 103 neonates, 51 (49%) were HRV-positive and 52 (51%) were HRV-negative.
