Congenital diaphragmatic hernia: a single-centre experience at Kepler University Hospital Linz.

Congenital diaphragmatic hernia (CDH) is found in about 1 of 3000 live births and is often complicated by pulmonary hypoplasia and alteration of the pulmonary arterial wall with resulting pulmonary hypertension. Since 2005, with the fusion of the children's hospital and the maternity clinic of the Kepler University Hospital Linz, affected neonates have been treated according to a standard protocol at our perinatal centre. Some prenatally measured parameters have been used to predict mortality, e.g., observed-to-expected lung-to-head ratio or lung volume measurements by nuclear magnetic resonance imaging. We performed a retrospective chart review of 67 new-borns with CDH treated at our institution to detect any predictors of hospital mortality from parameters routinely collected within the first 24 h of life. The term "liver up" was identified as a predictor of hospital mortality; OR 9.2 (95% CI 1.9-51.1, p = 0.002, sensitivity 79%, specificity 71%). In addition, the need for application of high-frequency oscillatory ventilation during the first 24 h was associated with mortality; OR 44.4 (95% CI 6.3-412.1, p = 0.001, sensitivity 85.7%, specificity 88%).

Status epilepticus, cardiac resuscitation, and posterior reversible encephalopathy syndrome after ingestion of viscous lidocaine: a plea for more childproof packaging of pharmaceuticals.

Ingestion of viscous lidocaine in children can lead to potentially lethal neurologic and cardiac effects. We report the case of a 2-year-old boy who developed posterior reversible encephalopathy syndrome 2 days after unobserved ingestion of about 500 mg viscous lidocaine (40 mg/kg of bodyweight). Initially, the child presented with convulsive status epilepticus and subsequent cardiac arrest necessitating cardiopulmonary resuscitation for eight minutes. After 2 days of full recovery, the child presented with progressive disorientation, dizziness, and visual neglect. Lasting for 2 days, these symptoms finally disappeared completely. Combined with the findings on cerebral magnetic resonance imaging, this episode was interpreted as posterior reversible encephalopathy syndrome. Two weeks after the ingestion, no neurologic and visual abnormalities were found. Viscous lidocaine is prescribed routinely for dentition or other painful lesions in the oral cavity in children. Despite the potential hazardousness of the drug, packaging of viscous lidocaine is not childproof. Therefore, physicians have to instruct the parents carefully to minimize the risk of overuse or accidental ingestion. In general, the use of viscous lidocaine should be limited.
