BACKGROUND This prospective study aimed to determine the spectrum and the main risk factors of surgical site infection (SSI) after neurosurgical procedures in our clinic. METHODS Consecutive patients undergoing neurosurgery between November 1, 2001, and November 1, 2002, were recruited for the study. All patients were followed for a minimum of 2 weeks(More)
OBJECT The inflammatory cells that accumulate at the damaged site after spinal cord injury (SCI) may secrete interleukin-6 (IL-6), a mediator known to induce the expression of inducible nitric oxide synthase (iNOS). Any increased production of NO by iNOS activity would aggravate the primary neurological damage in SCI. If this mechanism does occur, the(More)
OBJECT The authors examined the relationships of brain-tumor interfaces, specific magnetic resonance (MR) imaging features, and angiographic findings in meningiomas to predict tumor cleavage and difficulty of resection. METHODS Magnetic resonance imaging studies, angiographic data, operative reports, clinical data, and histopathological findings were(More)
A 43-year-old woman complaining of severe pain of the right side of the face was admitted to the Department of Neurosurgery. It had been present for three months and diagnosed as trigeminal neuralgia. The CT scan without contrast material had been considered normal at that time. Three months later, after a favourable response to carbamazepine, she suddenly(More)
OBJECTIVES Our aim was to investigate whether neutralization of rat interleukin 6 (IL-6) bioactivity attenuates inducible nitric oxide synthase (iNOS) up-regulation and ameliorates cerebral ischemic damage in a model of focal central nervous system (CNS) ischemia. METHODS Seventy rats were randomly allocated to groups: Group I (n=10) consisted of normal(More)
BACKGROUND Although there are some cases of cerebellar mutism in adults after posterior fossa surgery for cerebellar tumour it generally occurs in children. Reversible pathophsiology and the anatomical substrate of this syndrome still remain unclear. The predominance of cerebellar mutism in children is suggested to be related to the higher incidence of(More)
The present study was performed to investigate the effect of trapidil on ischemic damage of cells after spinal cord injury. The injury was produced by extradural clip compression of the exposed spinal cord in rats according to Rivlin and Tator. The ten rats in group 1 were used to determine normal findings without any surgery or medication. On the 15 rats(More)
BACKGROUND Choroid plexus papillomas are rare, accounting for less than 1% of all intracranial tumours in adults. However, they are relatively more common in childhood and constitute 1.5 to 4% of intracranial tumours. They are most often located in the lateral ventricle, followed by the fourth and third ventricles and, rarely, in the cerebellopontine angle.(More)
The results of percutaneous radiofrequency rhizotomy of lumbar spinal facets in 46 patients followed at least three months (mean 15 months) are reported and compared with those reported previously. Satisfactory pain relief three months after the procedure was achieved in 36.4 percent of patients without operations and in 41.7 percent of patients, with(More)
BACKGROUND Perimesencephalic nonaneurysmal hemorrhage is a benign form of subarachnoid hemorrhage with a low risk of rebleeding. The authors conducted a retrospective study to investigate the prognosis, possible prognostic factors, and long-term natural history in perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSH).
