Controlled Clinical TrialSerum neuron-specific enolase as a predictor of short-term outcome and its correlation with Glasgow Coma Scale in traumatic brain injury.
Elevated serum neuron-specific enolase levels are correlated with brain cell damage. Low scores according to Glasgow Coma Scale are also considered as serious poor prognostic factor. The aims of the study were to investigate whether there is a correlation between the two measurements in patients with traumatic brain injury and whether serum neuron-specific enolase levels have potential as a screening test to predict outcome. ⋯ There was a significant negative correlation between the serum neuron-specific enolase levels and Glasgow Coma Scale scores. The levels of neuron-specific enolase were significantly higher in the patients who died in 30 days after trauma and whose scores were lower than or equal to 8 points in Glasgow Coma Scale. Although there are several serious limitations of the use of neuron-specific enolase as a biomarker in traumatic brain injury (i.e., hypoperfusion, extracranial trauma, bleeding, liver, or kidney damage also increase the level of neuron-specific enolase), its concentrations may be useful as a practical and helpful screening test to identify neurotrauma patients who are at increased risk and may provide supplementary estimation with radiological and clinical findings.

Risk factors for posttraumatic cerebral infarction in patients with moderate or severe head trauma.
We examined the incidence and timing of posttraumatic cerebral infarction (PTCI) and provide predictive factors for the development of PTCI in patients with moderate or severe traumatic brain injury. Three hundred and fifty-three consecutive patients with moderate or severe head trauma were retrospectively reviewed to determine the incidence and timing of PTCI and to evaluate the effects of age, gender, admission Glasgow Coma Scores (GCS), decompressive craniectomy, brain herniation, and low systolic blood pressure (BP) on the development of cerebral infarction. Risk factors for posttraumatic cerebral infarction were evaluated using logistic regression analysis. ⋯ No relationship was found between PTCI and gender or increased age. Posttraumatic cerebral infarction is a relatively common complication in patients with head trauma that develops early in the clinical course. Low GCS, low systolic BP, brain herniation, and decompression craniotomy may be risk factors for PTCI in patients with moderate or severe traumatic brain injury.

Aneurysm clipping after endovascular treatment with coils: a report of 13 cases.
In 1996, Civit et al. (Neurosurgery, 38:955-961, 1996) reported a series of eight patients whose aneurysms were clipped after previous embolization with coils. This paper highlighted the safety of this surgery in second line, with a low complication rate and a favorable outcome. The two major surgical indications were either after deliberate partial occlusion of the aneurysm (N=3) or partial occlusion after endovascular treatment (N=3). ⋯ It is a safe and effective procedure, probably under-used. Nowadays, "hemostatic" and incomplete embolization of an aneurysm increases the risk of future growth and rebleeding of the residual pouch. An additional aneurysm clipping may therefore be required rapidly after embolization.
