Heart catheterization in a neonate by interacting magnetic fields: a new and simple method of catheter guidance.

Catheter guidance in a critically ill neonate can be difficult and hazardous. A new technique of directing a catheter based on the interaction of magnetic fields is described. A strong external permanent magnet is moved across the body surface to control the magnetic tip of a catheter in the body. We report on the first clinical case of such a heart catheterization in a neonate with complex congenital heart disease. This method can also be used for other invasive investigations in the neonatal period.

[Neonatal meningitis caused by Streptococcus mitis].

We report on a female newborn, 37 weeks of gestational age, who - after normal pregnancy and delivery - fell ill with a neonatal meningitis caused by streptococcus mitis. Until now this bacillus has been thought to be apathogen. The disease was cured completely by Penicillin therapy. The infection of a healthy newborn caused by streptococcus mitis, a streptococcus viridans, has not been described before.

[Echocardiographic diagnosis of a thrombus in the pulmonary artery following a banding operation].

In an infant with univentricular heart and banding of the pulmonary artery a thrombus developed in the pulmonary artery distal to the banding. The diagnosis was made at first by two-dimensional echocardiography and confirmed by angiography. The pathogenetic factors and the clinical relevance of this rare observation are discussed.
