AIM: Hyperpolarization-activated cyclic nucleotide-gated (HCN or h-channel) channels mediate hyperpolarization-activating currents in the hippocampus and neocortex. The aim of this study is to present prenatal h-channel gene expressions (HCN1 and HCN2; HCN1-Entrez-Gene ID: 84390; HCN2- Entrez Gene I...
AIM: In this report, we aim to determine the prognostic factors influencing the
length of survival in patients with low-grade gliomas.
MATERIAL and METHODS: In a retrospective evaluation, we have reviewed fiftythree
patients who had been operated between the years of 1980 and 2006. The
diagnoses...
Pages: 345-355
AIM: Optimal surgical pathway for lateral ventricle tumors is still controversial. The
purpose of this study is to discuss the factors that affected the preference of the surgical
techniques for removing lateral ventricle tumors.
MATERIAL and METHODS: 46 consecutive patients underwent operation f...
Pages: 356-365
BACKGROUND: Nogo-A is a myelin-associated neurite outgrowth inhibitory protein that
limits elongation of central nerve fibers, neuronal regeneration and plasticity. We
investigated the effect of delivering an inhibitory peptide that neutralizes Nogo-A on
neuronal recovery following mild cortical ...
Pages: 366-373
OBJECTIVE: In this report, we aimed to investigate the patients that presented at
our clinic complaint with diplopia due to the abducens nerve palsy and
neurosurgical disease.
METHODS: The study design was a retrospective review of ten cases with the
abducens nerve palsy. The causes of the abduc...
Pages: 374-379
OBJECTIVES: Temporal lobe epilepsy is the most common form of intractable
partial epilepsy in adults with hippocampal sclerosis accounting for the majority of
cases. Selective amygdalo-hippocampectomy (SEAH) is suggested as a safe and
effective surgical procedure with the advantage of a better co...
Pages: 380-386
BACKGROUND: Different data exist regarding long-term visual prognosis associated with
suprasellar meningiomas. The aim of this study was to determine the outcome of suprasellar
meningiomas with respect to short and long-term visual outcomes.
METHOD: During the period of 1997 to 2006, 45 patients ...
Pages: 387-391
AIM: The shunt infection rates vary from 2 to 39% among complications related to shunts
used for hydrocephalus treatment. Shunt infections are reported to be more common than
any other etiologies in newborn babies with myelomeningocele.
MATERIAL and METHODS: In this study, we performed a retrospe...

OBJECTIVE: The aim of this presentation is to show that the sublabial
transseptal transsphenoidal approach to pituitary adenomas is the least invasive
anatomic route with the lowest postoperative complication rates.
PATIENTS and METHOD: This study was based on a retrospective analysis of
276 pat...
Case Report
Pages: 392-396
Although the first reported surgery for lumbar disc herniation was published
many years ago, there still remains little agreement for the most effective
treatment protocol for symptomatic cases. Many patients with extruded lumbar
disc herniation require surgical intervention due to radiculopathy ...
Chondroma is a very unusual cartilagenous neoplasm of the spine. Here we are
present a case of spinal chondroma with radiculopathy. A 54-year-old female
patient consulted with progressive low back pain and left femoral numbness.
Lumbar spinal Magnetic resonance (MR) imaging studies showed an extr...
Cerebral extra-axial metastases mimicking meningioma are extremely rare.
Imaging characterictics may not always differentiate between meningioma and
metastatic tumors. A 68-year-old-woman who had been operated for renal cell
carcinoma 20 years ago presented with new symptoms of an intracranial ma...
Pages: 404-406
Totally cystic intradural extramedullary lesions are uncommon and form a
different spectrum of conditions as compared to the commonly seen intradural
extramedullary tumors. Spinal schwannomas are benign tumors arising from
spinal nerve root sheaths and are the most common intradural extramedullar...
Diffuse idiopathic skeletal hyperostosis (DISH) or Forestier's disease is a
common disorder of unknown etiology that is characterized by ossification of
the anterior longitudinal ligament of the spine and various extra-spinal
ligaments. We present the case of a 54-year-old woman with progressive
...
Subfrontal schwannomas are rare lesions. They can be misdiagnosed as
olfactory meningiomas or neuroblastomas. We report a case of giant
schwannoma involving the anterior cranial fossa; the frontal and ethmoid
sinuses and nasal cavities. The patient presented with a year-long history of
increasin...
Pages: 415-419
We present a case of posttraumatic infarction in the territory supplied by the
lateral lenticulostriate artery after a minor head injury in a child. A 2.5-year-old
child was admited to our emergency room after a head-on fall from a height of
50cm. He developed a right hemiparesis and he could not...
Pages: 420-424
Ossified chronic subdural hematoma is a very rarely seen entity. We present here
a 22-year-old male who had presented with severe headache consequent to
brain compression caused by bifronto-parieto-temporal ossified subdural
hematoma. We evaluated our method and surgical intervention in the light...

OBJECTIVES: Intracranial metastasis of ovarian tumours is rarely seen with an incidence 0.1-
5% but simultaneous diagnosis of primary undifferentiated carcinoma of the ovary and its CNS
metastasis has not been published previously.
MATERIAL and METHODS: A 56-year-old woman presented with headache...
Ventriculo-peritoneal shunt, one of the most common surgical procedures
performed by neurosurgeons all over the world has been associated with a
number of complications; the most common being infection and mechanical
failure. Most of these complications tend to increase morbidity with prolonged
...
OBJECTIVE: Blister-like aneurysms are small hemispherical bulges that usually originate
from the anteromedial wall of the distal internal carotid artery and cause significant
subarachnoid hemorrhage. It is very important to recognize this novel lesion as a different
type of aneurysm than ordinary...
