Threshold hemoglobin level for delayed cerebral ischemia: A single-center retrospective analysis.

Background: Delayed cerebral ischemia (DCI) occurs in approximately 20%-30 % of patients with subarachnoid hemorrhage (SAH). This is the most common complication of SAH and has a high mortality rate. In the present study, we investigated the relationship between hemoglobin (Hb) values and DCI and aimed to determine a cutoff Hb value to be used as a predictor of DCI.

Aneurysmal Subarachnoid Hemorrhage; Early Surgery; Neurosurgeons Experience; Patient Outcome.

Background: This study examined the impact of neurosurgeons' experience on surgical timing and outcomes in aneurysmal subarachnoid hemorrhage (aSAH) and questioned the adherence to early surgery as recommended by recent guidelines.

Methods: A retrospective analysis of 196 aSAH patients treated between 2013 and 2020 was conducted. Variables included age, sex, initial Glasgow Coma Scale (GCS) scores, World Federation of Neurological Surgeons grades, Fisher's grades, rebleeding, hydrocephalus, and preoperative-postoperative neurological status.

Neuroprotective Effects of Coenzyme Q10 and Ozone Therapy on Experimental Traumatic Spinal Cord Injuries in Rats.

Objective: This study investigates the neuroprotective effects and functional recovery potential of Coenzyme Q10 (CoQ10) and ozone therapy in spinal cord injury (SCI).

Material And Methods: In this study, 40 female Sprague-Dawley rats were divided into 5 groups of 8. Surgical procedures induced spinal cord trauma in all groups, except the control group.

Applications of enhanced recovery after surgery protocols for unruptured anterior circulation aneurysms in tertiary-level healthcare institutions: a national study.

Objective: Enhanced recovery after surgery (ERAS) protocols are standardized perioperative care that reduce patients' stress response during hospitalization and improve hospitalization time, complication rates, costs, and readmission rates. This study aimed to investigate the application rate of protocols for elective craniotomy in the surgery of unruptured anterior circulation aneurysms (AnCAs) at tertiary-level healthcare (TLH) institutions in Türkiye and its effect on the outcomes of the patients.

Methods: An electronic survey was sent to all Turkish TLH institutions (n = 127) between May and June 2023.

Clinical Significance of Pneumocephalus in Pediatric Mild Traumatic Brain Injury.

Objectives: Mild traumatic brain injury (mTBI) comprises most (70%-90%) of all pediatric head trauma cases seeking emergency care. Although most mTBI cases have normal initial head computed tomography scan, a considerable portion of the cases have intracranial imaging abnormalities on computed tomography scan. Whereas other intracranial pathological findings have been extensively studied, little is known about the clinical significance of pneumocephalus in pediatric mTBI.

Flow diverter stent treatment for unruptured supraclinoid segment internal carotid artery aneurysms: a Turkish multicenter study.

Objective: Despite the relatively high success of surgical clipping of supraclinoid segment aneurysms of the internal carotid artery (ICA), flow diverter (FD) stent therapy is becoming increasingly used for these aneurysms. This study aims to evaluate the characteristics of FD placement for unruptured ICA supraclinoid segment aneurysms at 6 different centers with different experience levels in Türkiye.

Methods: In this retrospective, multicenter study, the authors reviewed the demographic information, aneurysm shape/dimensions (neck, aspect ratio, dome/neck ratio, and maximum diameter), preoperative antiplatelet regimen, FD stent brand, perioperative complications, intervention time, clinical (modified Rankin Scale) and radiological (O'Kelly-Marotta [OKM] grading scale) outcomes, and follow-up time of 54 patients.

A Novel Decision-Support Tool (IniCT Score) for Repeat Head Computed Tomography in Pediatric Mild Traumatic Brain Injury.

Background: The necessity of computed tomography (CT) has been questioned in pediatric mild traumatic brain injury (mTBI) because of concerns related to radiation exposure. Distinguishing patients with lower and higher risk of clinically important TBI (ciTBI) is paramount to the optimal management of these patients.

Objective: This study aimed to analyze the imaging predictors of ciTBI and develop an algorithm to identify patients at low and high risk for ciTBI to inform clinical decision making using a large single-center cohort of pediatric patients with mTBI.

Effect of topical rifamycin application on epidural fibrosis in rats.

Objectives: This study aims to investigate the effects of topical rifamycin SV application on epidural fibrosis formation in a rat model.

Materials And Methods: Between March 2015 and April 2015, a total of 20 Wistar rats were equally and randomly divided into laminectomy only group (control group) and laminectomy and rifamycin SV group (treatment group). Laminectomy was performed between L3-L5 in all rats.

Resection of an anterolateral mesencephalic cavernoma via transsylvian/transuncal approach in a child.

This video demonstrates the resection of an anterolateral mesencephalic cavernous malformation (CM) through a transsylvian/transuncal approach. A 10-year-old girl presented with progressive headache and left-sided spastic hemiparesis. Neuroimaging revealed a 20-mm CM located in the right anterolateral midbrain/cerebral peduncle.

Anti-edematous, anti-inflammatory and neuroprotective effect of etanercept in acute stage in experimental head injury.

Background: To study the anti-edematous, anti-inflammatory, and neuroprotective effect of etanercept in the model of experimental head injury.

Methods: In this study, 40 male-adult Spraque-Dawley rats, with weight ranging from 250g to 300g, were used. The rats are divided into groups as control; non-penetrating trauma; trauma +NS; post-traumatic normal saline; trauma + D; post-traumatic dexamethasone and trauma + E.

Active Rebleeding of a Ruptured Middle Cerebral Artery Aneurysm During Diagnostic Catheter Angiography.

Rebleeding of cerebral aneurysms has been previously reported during diagnostic angiography. However, capturing the exact moment of active rebleeding of a cerebral aneurysm during angiography is extremely rare. Here, a case of a rebleeding middle cerebral artery aneurysm during diagnostic digital subtraction angiography (DSA) was illustrated, accompanied with a video demonstration of the incident which is the only one in the literature.

The Protective Effect of Omeprazole Against Traumatic Brain Injury: An Experimental Study.

Background: The development of secondary brain injury via oxidative stress after traumatic brain injury (TBI) is a well-known entity. Consequently, the aim of the present study was to evaluate the role of omeprazole (OM) on rat model of TBI.

Methods: A total of 24 male rats were used and divided into 4 groups as follows; control, trauma, OM, and methylprednisolone (MP).

The effects of ankaferd blood stopper and microporous polysaccharide hemospheres on epidural fibrosis in rat laminectomy model.

Purpose: To investigate whether topically administered hemostatic agents ankaferd blood stopper and microporous polysaccharide hemospheres can decrease epidural fibrosis after laminectomy in rats.

Methods: Eighteen adult male Sprague-Dawley rats were equally and randomly divided into three groups. In the treatment groups, ankaferd blood stopper and microporous polysaccharide hemospheres topically administrated upon duramater surface after laminectomy.

[Occipital condyle fractures: a case report].

Occipital condyle fractures are rare, and conservative treatment is sufficient for many cases. Surgical treatment may be required if the condyle fracture is accompanied by atlantooccipital dislocation. Unfortunately, condyle fracture generally cannot be diagnosed with X-ray in the emergency department.
