The authors present the results of Gamma Knife stereotactic radiosurgery performed in a series of children with arteriovenous malformations (AVMs). Between June 2005 and January 2014, 75 patients 18 years old or younger received Gamma Knife radiosurgery for AVMs. Of these, 58 patients were eligible for further analysis. The median age of the population was(More)
Oxygen free radicals may be implicated in the pathogenesis of ischemia-reperfusion damage. It is known that 2-chloroadenosine (2-CADO) has neuromodulatory effects and prevents the neuronal damage seen in the period of postischemia reperfusion. However, direct effects of 2-CADO on lipid peroxidation have not been investigated previously. The attack on the(More)
PURPOSE The scar tissue that forms after lumbar dissection is a severe complication and a cause of lumbar and radicular pain. It was recently shown that radiotherapy could inhibit peridural fibrosis after laminectomy. In this study, the efficiency of external irradiation was compared with spinal membrane application. METHOD AND MATERIALS Thirty male New(More)
1. In the present study we have studied the effects of deferoxamine treatment on lipid peroxidation and Na-K ATPase activity after experimental induction of subarachnoid haemorrhage (SAH) in guinea pigs. 2. We assessed the extent of lipid peroxidation by measuring the level of malondialdehyde and Na-K ATPase activity in 3 different groups (sham-operated,(More)
T1. The effect of 2-chloroadenosine, an adenosine analogue, on brain ATP level and Na,K ATPase activity in ischemia and reperfusion was studied. 2. Na,K ATPase activity decreased in both ischemia and reperfusion. Although the ATP level decreased in ischemia, it increased with reperfusion (P < 0.05). 3. It is concluded that 2-chloroadenosine treatment(More)
BACKGROUND Extensive research has focused on neuroprotection after spinal cord trauma to alleviate the effects of secondary injury. This study aims to investigate the neuroprotective effects of gabapentin in experimental spinal cord injury. METHODS Thirty-six adult, male Wistar rats received spinal cord injury using the clip compression method. Animals(More)
OBJECTIVE One of the important causes of failed back surgery is the extensive peridural fibrosis collecting in the surgical field after spinal surgeries. Today we know that inflammatory mechanisms mediated by the immune system of the body plays an important role in generation of fibrosis. Azithromycin, a macrolide antibiotic, has proven immunomodulatory(More)
BACKGROUND Fractures in the region of the sella turcica (ST) are usually associated with severe blunt head trauma and may produce many complications. The true incidence is difficult to assess since there have been only about 30 cases reported in the literature. METHODS A total of 470 computed tomography (CT) sections--with optimum bone window images of(More)
AIM To investigate the effects of hyperbaric oxygen treatment on epidural fibrosis formation in an experimental laminectomy model. MATERIAL AND METHODS Twenty-four Wistar rats underwent L5-L6 total laminectomy and divided into three groups. Animals in the control group received no further treatment while animals in short and long term groups received 2,5(More)
