Shunt infection remains the foremost problem of shunt implantation after mechanical malfunctions. Diversionary cerebrospinal fluid shunt implantation has a high complication rate, with 5% to 15% of such shunts becoming infected. Of these infections, 70% are diagnosed within 1 month after surgery and more than 90% within 6 months. Shunt infection in the vast majority of cases is therefore a complication of shunt surgery. The authors review their experience with shunt implantation during two time periods. From January, 1978, to December, 1982, 302 children with hydrocephalus underwent 606 operations. Among these children, 47 (15.56%) developed a proven shunt infection, with an incidence of infection per procedure of 7.75%. As a result of this study, a new protocol for shunt procedures involving modifications in the immediate pre-, intra-, and postoperative management of children undergoing shunt implantation was initiated. With this new protocol, 600 children underwent a total of 1197 procedures between January, 1983, and December, 1990. The incidence of shunt infection decreased dramatically, with two infections (0.33%) in 600 patients and a per-procedure rate of 0.17%. The overall annual risk of a shunt infection in the pediatric neurosurgical unit is currently 1.04%.

This study and analysis of the literature further highlight that total tumor removal is the treatment of choice for ependymomas in children. Postoperative measurement of residual tumor is required, especially because a subgroup of patients might be treated by surgery alone. Median infratentorial ependymomas have to be distinguished from the lateral type. Appropriate and reproducible histological parameters and Ki-67 LI are of interest as predictors of outcome.

Most of the children seen by specialists in neonatalogy, neuropaediatrics or neurosurgery do not have any problems in starting with oral feeding after a period of tube feeding lasting between 15 and 20 days. Children who have been tube fed for a longer period, however, can find it very difficult or even impossible to re-establish oral feeding when they have sufficiently recovered from their underlying problem. To cope with this situation we propose a procedure based on the afferentation or re-afferentation of the oropharyngeal cavity by sensory stimulations and by re-establishment of the biological clock (circadian rhythm) by applying these stimulations during tube feeding at regular hours. In 19 children who showed difficulties oral feeding became possible a short time after such a procedure had been applied. If the principles of swallowing neurophysiology and the biological rhythm are respected, this procedure, which also involves a contribution from the family, leads to quicker oral feeding and shorter stay in hospital.
