Review Case Reports
An unusual presentation of thoracic cord compression by a dorsal arachnoid cyst in a 14-month-old boy. A discussion of the case and review of the literature.
Spinal arachnoid cysts are a rare cause of spinal cord compression in children and presenting symptoms may be subtle. We present a neurologically intact 14-month-old boy who presented with pain and postural irritability from a thoracic arachnoid cyst.

A simple way of evaluating surgical outcomes is to compare mortality and morbidity. Such comparisons may be misleading without a proper case mix. The POSSUM scoring system was developed to overcome this problem. ⋯ The difference between observed and predicted deaths at different risk levels was not significant with P-POSSUM (p = 0.424) and was significantly different with POSSUM score (p < 0.001). P-POSSUM scoring system was highly accurate in predicting the overall mortality in neurosurgical patients. In contrast, POSSUM score was not useful for prediction of mortality.

Randomized Controlled Trial
Effects of fluid therapy following aneurysmal subarachnoid haemorrhage: a prospective clinical study.
Blood transfusions and intravenous fluids are commonly employed as rescue therapy for delayed cerebral ischaemia following aneurysmal subarachnoid haemorrhage (aSAH). We sought to determine effects of various fluid supplements on clinical outcome in patients following aSAH. Clinical events and laboratory data of 160 aSAH patients were prospectively collected as part of 2 randomised controlled trials. ⋯ Colloid fluids (OR 2.53/L/day, p = 0.025) promoted unfavourable outcome at 6 months (OR 4.45, p = 0.035), while crystalloids decreased unfavourable outcome (OR 0.27/L/day, p = 0.005). Associations between synthetic colloids and crystalloids with GOS at 6 months were dose-related. Intravenous fluid therapy using synthetic colloids or blood transfusions may be associated with increased unfavourable outcome following aSAH.

Multicenter Study
Epidemiology of ventriculostomy in the United States from 1997 to 2001.
Ventriculostomy is a common practice in neurosurgery, but the annual trend of this procedure in the United States has not been reported in the literature. This study evaluates the annual trend during a recent 5-year period. Between 1997 and 2001, a retrospective review was undertaken concerning all patients in the Nationwide Inpatient Sample (NIS) who had undergone ventriculostomy. ⋯ Patient and hospital demographic characteristics were consistent during the study period. By extrapolation of the data, the prevalence of ventriculostomy in the United States averaged 24,380 per year. This study is the first to comprehensively document data concerning the epidemiology of this common procedure.

Spontaneous intracranial hypotension (SIH) is an uncommon clinical entity that is often diagnosed after a delay, or it is misdiagnosed due to the variety of clinical presentations and the associated radiological findings. We present here a case of SIH associated with chronic subdural haematoma (SDH) and subarachnoid haemorrhage. Following the diagnosis of the SIH, the patient underwent injection of an epidural blood patch for the SIH and burr hole trephination was done for treating the chronic subdural haematoma.
