Identification of Radiological and Clinical Factors that Increase the Risk of Chronic Subdural Hematoma Recurrence.

Aim: To determine risk factors predicting chronic subdural hematoma (CSH) recurrence is a common type of intracranial hemorrhage in elderly patients. Despite improved medical diagnosis and treatment, the reoperation rate remains high.

Material And Methods: A retrospective review of 291 CSH patients admitted to our department was performed.

Stereotactic radiosurgery for tumors of the pineal region: A single-center experience.

Tumors of the pineal region (TPRs) are rare neoplasms that are surgically challenging to resect. Conventional treatment strategies are available, but gamma knife radiosurgery (GKRS) is an alternative approach. This study presents a single-center experience with GKRS performed for TPR with and without histopathological diagnoses.

Microsurgical and fiber tract anatomy of the interthalamic adhesion.

Objective: The authors of this study aimed to define the microanatomy of the interthalamic adhesion (ITA) using microfiber dissection, magnetic resonance (MR) tractography, and histological analysis.

Methods: Sagittal, coronal, and axial MR images from 160 healthy individuals 2-82 years of age were examined. The relationships between age range and ITA morphology as well as between gender and ITA morphology were evaluated statistically.

All aspects of sciatic nerve injection injury: an experiment with 78 rats.

Background: In this study, we evaluate sciatic nerve injuries due to intramuscular injections, which is an important medicolegal problem frequently encountered in medical practice, with an extended experimental rat model of peripheral nerve injury.

Methods: A total of 78 male Wistar albino rats were divided into five main groups, including a control group, a sham saline group, and groups that received benzathine penicillin G, diclofenac sodium, and dexamethasone, respectively. These pharmaceutical agents were applied to the sciatic nerves of all rats after exploration in the epineurial, endoneurial, and intrafascicular compartments, excluding the control group.

The Effects of Necrostatin-1 on Cerebral Vasospasm- Induced Subarachnoid Hemorrhage.

Aim: In this study, we investigated the effects of necrostatin-1 (NEC-1) on subarachnoid hemorrhage (SAH)-induced vasospasm in a rat model.

Material And Methods: 59 male Wistar albino rats were randomly divided into six groups: control (group 1), sham (group 2), decapitation one hour after SAH (group 3), decapitation 48 hours after SAH (group 4), NEC-1 given 15 minutes before SAH and decapitation one hour after SAH (group 5), and NEC-1 given 24 hours after SAH and decapitation 48 hours after SAH (group 6). NEC-1 (1 uq) was administered intracisternally in dimethyl sulfoxide (DMSO) (2.

Evaluation of third ventriculostomy outcome by measuring optic nerve sheath diameter in adult hdyrocephalus.

Objective: It is difficult to demonstrate the success of the procedure in patients with third ventriculostomy. We evaluated that optic nerve sheath diameter (ONSD) measurement, which can reflect intracranial pressure, may be a criterion for decision of endoscopic third ventriculostomy (ETV) success.

Methods: 28 adult patients suffering long overt standing ventriculomegaly (LOVA) who performed ETV were included in this retrospective study.

Sciatic Nerve Injuries from Gluteal Intramuscular Injection According to Records of the High Health Council.

Aim: To analyze the cases discussed at the High Health Council (HHC) and to determine the solutions for problems related to gluteal intramuscular injection (IMI) applications.

Material And Methods: In a 10-year period, the cases of IMI-related sciatic nerve injury (SNI) referred for an opinion from the HHC of Turkey were reviewed. The cases were analyzed based on demographic features, degree of nerve damage, side of gluteal injection, injected drugs, primary disease, appropriateness of parenteral therapy indications, and management.

Once the Light Touch to the Brain: Cytotoxic Effects of Low-Dose Gamma-Ray, Laser Light, and Visible Light on Rat Neuronal Cell Culture.

Objective: We aimed to evaluate the effects of gamma-ray, laser light, and visible light, which neurons are commonly exposed to during treatment of various cranial diseases, on the viability of neurons.

Materials And Methods: Neuronal cell culture was prepared from the frontal cortex of 9 newborn rats. Cultured cells were irradiated with gamma-ray for 1-10 min by (152)Eu, (241)Am, and (132)Ba isotopes, visible light for 1-160 min, and laser light for 0.

Neuroendoscopic approach to quadrigeminal cistern arachnoid cysts.

Objective: The introduction of neuroendoscopy has provided a minimally invasive modality for the surgical treatment of quadrigeminal arachnoid cysts. Three pediatric patients with arachnoid cyst of the quadrigeminal cistern treated by endoscopic fenestration are reported.

Materials And Methods: The hospital records of patients were retrospectively rewieved.

A preliminary histopathological study of the effect of agmatine on diffuse brain injury in rats.

The present study evaluates the effects of agmatine on histopathological damage following traumatic injury using a clinically relevant model of diffuse brain injury. A total of 27 male Sprague-Dawley rats weighing 200-225 g were anaesthetised and subjected to head trauma using Marmarou's impact-acceleration model. The rats were then separated into two main groups: one was treated with agmatine and the other with saline for up to 4 days immediately after head trauma.

Treatment of spinal hydatid disease: a single center experience.

In Turkey, spinal hydatidosis remains a serious health problem that is associated with high morbidity and mortality. This study was undertaken to analyze the clinical, radiological, and surgical aspects and outcomes for five patients with spinal hydatidosis who were treated surgically at the Department of Neurosurgery of Ataturk University, Turkey. Despite the introduction of modern surgical and pharmacological therapy the disease remains difficult to cure, and patient outcomes are not satisfactory because of the high incidence of recurrence.

Acute interhemispheric subdural hematoma due to hemodialysis: case report.

Background: Acute interhemispheric subdural hematoma (AISH) is an extremely limited complication in patients on maintenance hemodialysis. Diagnostic difficulties result from a fact that symptoms of acute hematoma such as headache, nausea, vomiting, apathy, sleepiness, paresthesia and seizures may also suggest dysequilibrium syndrome, dialytic dementia as well as hypertensive encephalopathy.

Case Description: A case of acute interhemispheric subdural hematoma during long-term dialysis is presented.

Sphenoid sinusitis disguised by precocious puberty.

Isolated sphenoid sinusitis in childhood is a rare clinical entity which is often very difficult to diagnose, hence, it can easily be misdiagnosed. The rarity of this entity is related to the absence at the sinus in children and the lack of development in patients with sinopathology. The first presentation of this disorder might be disguised by another disease.

The clinical, radiological and surgical aspects of cerebral hydatid cysts in children.

A series of 13 pediatric patients underwent surgery for cerebral hydatid cysts at the Department of Pediatric Neurosurgery between 1993 and 2003. Headache and motor weakness were the main initial signs of these patients. A round cystic lesion was the characteristic appearance on computed tomography of each patient.
