    Abstract:

    AIM: The purpose of this study was to investigate the time course(s) of the cerebrospinal fluid and serum chitotriosidase changes in patients with aneurysmal subarachnoid hemorrhage and to show whether cerebrospinal fluid and/or serum chitotriosidase levels might be used as a specific marker for disease severity. MATERIAL and METHODS: Chitotriosidase in the cerebrospinal fluid and serum was measured within the first 3 days, at Day 5 and at Day 7 after aneurysmal subarachnoid hemorrhage in 20 patients, and the results were compared to 8 patients with Normotensive Hydrocephalus. RESULTS: Mean cerebrospinal fluid chitotriosidase levels were found to be higher on days 5 and 7 of subarachnoid hemorrhage and the serum levels were always higher than controls at all times in subarachnoid hemorrhage patients. However, no relationship was found between elevated chitotriosidase levels and the clinical parameters including symptomatic vasospasm and outcome at 6 months. CONCLUSION: Results indicate that chitotriosidase is elevated in the acute stages of subarachnoid hemorrhage but is not a specific marker of subarachnoid hemorrhage

    Abstract:

    INTRODUCTION: The purpose of this study was to investigate the time course(s) of the serum hyaluronidase levels in patients with aneurysmal subarachnoid haemorrhage and to show whether there is a correlation between symptomatic vasospasm and serum levels of hyaluronidase. METHODS: This prospective, open, non-randomised clinical study consisted of 20 patients with aneurysmal subarachnoid haemorrhage, and eight patients with Normotensive Hydrocephalus who served as the control group. Serum hyaluronidase levels were detected within the first three days, days five and seven after aneurysmal subarachnoid haemorrhage, and the results were compared with those from the control group. The results were also compared with those of the clinical parameters, including the patient's outcome at six months and symptomatic vasospasm. RESULTS: Mean serum hyaluronidase levels were higher on days five and seven, and comparisons with either day five (p-value is 0.001) and/or day seven (p-value is 0.00001) showed a statistical difference between subarachnoid haemorrhage and controls. However, no relationship was found between elevated serum hyaluronidase levels and the clinical parameters including symptomatic vasospasm (p-value is greater than 0.05) and outcome at sixth months (p-value is greater than 0.05). CONCLUSION: Our results indicate that serum hyaluronidase is elevated in the acute stage(s) of subarachnoid haemorrhage; however, no difference was found between serum hyaluronidase levels and subarachnoid haemorrhage severity. Clinical studies with larger population of patients with aneurysmal subarachnoid haemorrhage are required.

  • idiopathic Normotensive Hydrocephalus neuropsychologic evaluation after ventriculo atrial shunt
    Srpski Arhiv Za Celokupno Lekarstvo, 1992
    Co-Authors: E Stefanova, D Pavlovic, G Ocic
    Abstract:

    : Two patients with normal-pressure Hydrocephalus were assessed with Luria Nebraska Neuropsychological Battery, before ventriculo-atrial shunting and six months later. The best improvement was recorded in attention, visuospatial and intellectual functions. It is well documented that normal-pressure Hydrocephalus dementia can be reversible if proper selection for neurosurgical treatment is made. Cognitive outcome of ventriculo-atrial shunting in normal-pressure Hydrocephalus is best assessed with the appropriate neuropsychological testing.
