Objectives-The fibreoptic device is a type of intracranial pressure monitor which seems to oVer certain advantages over conventional monitoring systems. This study was undertaken to analyse the accuracy, drift characteristics, and complications of the Camino® fibreoptic device. Methods-One hundred and eight Camino® intracranial pressure (ICP) devices, in their three modalities, were implanted during 1997. The most frequent indication for monitoring was severe head injury due to road traYc accidents. Results-Sixty eight probe tips were cultured; 13.2% of the cases had a positive culture without clinical signs of infection, and 2.9% had a positive culture with clinical signs of ventriculitis. The most common isolated pathogen was Staphylococcus epidermidis. All patients were under cephalosporin prophylaxis during monitoring. Haemorrhage rate in patients without coagulation disorders was 2.1% and 15.3% in patients with coagulation abnormalities. Drift characteristics were studied in 56 cases; there was no drifting from the values expected according to the manufacturer's specifications in 34 probes. There was no relation between direction of the drift and duration of placement, nor between drift and time. Conclusions-Although the complication and drift rates were similar to those reported elsewhere, there was no correlation between the direction of the drift and long term monitoring despite the fact that some published papers refer to overestimation of values with time with this type of device.

We report a case of an infantile hemiplegia seizure syndrome (IHSS) that presented with intractable reflex audiogenic startle epilepsy which in itself is an uncommon form of seizure disorder. Peri-insular hemispherotomy provided complete seizure control. Also of particular interest was that this syndrome resulted from an iatrogenic brain injury sustained during the course of a caesarian section. We review the different mechanisms of birth injury reported in the literature and, discuss the physiopathogenesis of the hemispheric damage in this patient. We also review the literature on "reflex epilepsy" as it applies to this case. Intractable reflex audiogenic (startle) epilepsy in IHSS submitted to hemispherotomy has not previously been reported.

Definitive or probable diagnosis of NCC is based on clinical, imaging, immunological, and epidemiological criteria. In patients with inactive disease only symptomatic treatment is indicated. In active parenchymal forms there are not consensus if antiparasitic treatment is indicated. However, in extraparenchymal active disease aggressive treatment with antiparasitic agents and steroids is recommended. In cases of intracranial hypertension, neurological deficits or hydrocephalus surgery is the treatment of choice.
