A paradoxical rise of neonatal seizures after treatment with vitamin B6

We report the case of a newborn with intractable epileptic seizures developing a paradoxical rise of seizure frequency and electroencephalogram alterations after administration of vitamin B6. We have been unable to determine the aetiology of this disorder. In a newborn presenting with drug-resistant epileptic seizures, the first therapeutic option remains the application of intravenous pyridoxine, but the physician should be aware of the risk of an increase in seizure frequency.

Forced oscillation technique in infants and young children

Due to its non-invasive character, the forced oscillation technique has gained importance in clinical research in infants and young children. Standardisation has enabled systematic and comparable measurements to be made in different laboratories throughout the world. The theoretical conditions are now fulfilled for use of these techniques in the clinical environment. This review discusses the principles, usefulness and pitfalls of various forced oscillation techniques in a research and clinical environment and the present and future clinical applications in children. It will focus particularly on the role of infant and preschool lung function as forced oscillation only requires minimal cooperation.
