Analysis of different treatment modalities of tethered cord syndrome

Introduction: Although MRI has improved the diagnosis of tethered cord, many controversies still exist in the treatment of tethered cord syndrome (TCS). Especially the indications for and timing of surgical release have remained topics of discussion. Materials and methods: We retrospectively analysed a group of 41 spina bifida occulta (SBO) patients with a tethered cord to evaluate the results of treatment. Patients were divided into four groups. Twelve asymptomatic tethered cord patients underwent prophylactic surgery (group 1). Ten patients were operated upon because of progressive symptoms (group 2). In the third group 9 patients were treated conservatively at first, but underwent surgery after further progression of symptoms. The 10 patients in group 4 were treated conservatively. Results: The course of symptoms was analysed in the separate groups. Patients in group 1 remained stable during the mean follow-up of 5.7 years. Neurological symptoms appeared to improve most after early surgery (group 2), but progression of symptoms continued in spite of surgical release

The prognostic value of serial EEG recordings following acute neonatal asphyxia in full-term infants

Perinatal asphyxia is one of the major causes of non-progressive neurological deficits seen in children. It is reported that currently no set of parameters allowing for accurate prediction of prognosis following severe perinatal asphyxia is available. Even electroencephalogram (EEG) recordings, which are known to give a fairly good prediction of long-term outcome, have their flaws. The aim of this prospective study was to evaluate the additional value of serial EEGs in full-term infants. In all, 36 infants were enrolled. All met strict entrance criteria, received standard treatment and underwent two EEGs according to a pre-set protocol: the first between 12 and 36 hours post-partum, the second between 7 and 9 days post-partum. It is clearly demonstrated that serial EEG recordings do enhance the prognostic value of the EEG. Moreover, distinct progression seen in serial EEGs is highly prognostic for a normal outcome and has even more prognostic value than one single severely abnormal EEG. A better indication of future outcome is obtained from serial EEGs
