Usage of 3D prints with ceramic coating applied as neurological tools - preliminary research.

: The paper shows a preliminary study of the basic strength parameters of printed parts made of biocompatible polymers with ceramic layers applied to increase the strength of the tool cutting surface. : The specimens were made from different materials and using different 3D printing technologies and the working surfaces that will eventually form the cutting element of the tool were coated with AlO. Gloss tests were conducted, properties of the coating, a scratch test of the coated surface, also evaluated surface to-pography.

Prophylactic use of dural tenting sutures in elective craniotomies in adults-is it necessary? A study protocol for a multicentre, investigator- and participant-blinded randomised, parallel-group, non-inferiority trial.

Background: In the early days of neurosurgery, extradural haemorrhages (EDHs) contributed to a high mortality rate after craniotomies. Almost a century ago, Walter Dandy reported dural tenting sutures as an effective way to prevent postoperative EDH. Over time, his technique gained in popularity and significance to finally become a neurosurgical standard.

Necessity of dural tenting sutures in modern neurosurgery: protocol for a systematic review.

Introduction: The ongoing need for dural tenting sutures in a contemporary neurosurgical practice has been questioned in the literature for over two decades. In the past, these sutures were supposed to prevent blood collecting in the potential space between the skull and the dura by elevating the latter. Theoretically, with modern haemostasis and proper postoperative care, this technique should not be necessary and the surgery time can be shortened.

Morphological, hemodynamic, and clinical independent risk factors for anterior communicating artery aneurysms.

Background And Purpose: The pathogenesis of cerebral aneurysms still raises some controversies. The aim of this study was to identify morphological, hemodynamic, and clinical independent risk factors for anterior communicating artery (ACoA) aneurysm development.

Methods: Computed tomography angiography and transcranial color-coded sonography were performed in 77 patients with a nonbleeding ACoA aneurysm and in 73 controls.

Transcranial color-coded Doppler assessment of cerebral arteriovenous malformation hemodynamics in patients treated surgically or with staged embolization.

Objective: The etiology of hemodynamic disturbances following embolization or surgical resection of arteriovenous malformations (AVMs) has not been fully explained. The aim of the study was the assessment of the selected hemodynamic parameters in patients treated for cerebral AVMs using transcranial color-coded Doppler sonography (TCCS).

Materials And Methods: Forty-six adult patients (28 males, 18 females, aged 41 ± 13 years, mean ± SD) diagnosed with AVMs who were consecutively admitted to the Department of Neurosurgery between 2000 and 2012 treated surgically or with staged embolization were enrolled in the study.

Radiological findings in relation to the neurodevelopmental outcome in hydrocephalic children treated with shunt insertion or endoscopic third ventriculostomy.

Purpose: The aim of the study was to compare the radiological indicators of effectiveness for hydrocephalus treatment in children operated on under the third year of age with the use of shunt insertion (SI) and endoscopic third ventriculostomy (ETV). The effectiveness was considered in terms of postoperative neurodevelopment in correlation to pre- and postoperative radiological findings.

Methods: The examined group consisted of 46 children operated on for hydrocephalus in the Division of Pediatric Neurosurgery in Katowice, Poland.

Posterior fossa brain tissue injury: developmental, neuropsychological, and neurological consequences of brain tumors in children.

The aim of the study was the functional neurodevelopmental assessment of children with posterior fossa tumors, specifically examining whether tumor location in particular cerebellar structures determines particular neuropsychological deficits. The examined group consisted of 34 children treated between 1999 and 2007 at the Division of Pediatric Neurosurgery Silesian University Medical School in Katowice, Poland. Twelve girls and 22 boys between 5 and 21 years of age were examined.

Is neuroradiological imaging sufficient for exclusion of intracranial hypertension in children? Intracranial hypertension syndrome without evident radiological symptoms.

There are still many important questions about algorithms and clinical scenarios in the context of children with clinical intracranial hypertension symptoms (IHS) without radiological findings. Such conditions could appear in different clinical situations, including slit ventricle syndrome, overdrainage syndrome, normal volume hydrocephalus, or idiopathic intracranial hypertension. Many articles have defined specific treatment strategies for various forms of IHS, including ventriculoperitoneal shunting, medication for shunt-related migraine, steroids, and valve upgrades with antisiphoning devices or programmable systems.

Primary pituitary lymphoma.

Primary CNS lymphoma (PCNSL) is now thought to constitute 3% of all intracranial neoplasms. PCNSL occurrence in the sella turcica region is an extremely rare finding. We present a 37-year-old male with primary pituitary lymphoma treated in our department.

Malformations of cortical development in children: clinical manifestation, neuroimaging and neuropathology in selected cases.

Cerebral cortical development can be divided into three steps: cellular proliferation, neuronal migration and organization. Based on known pathologic, genetic and neuroimaging features a classification for malformations of cortical development was proposed by Barkovich in 2001, and updated in 2005. Malformations of cerebral cortex development (MCCD) often demonstrate epileptic seizures and delay in psychomotor development.

Evaluation of quality of life and clinical status of children operated on for intractable epilepsy.

Aim: The aim of the study was evaluation of surgical treatment of epilepsy measured by changes in quality of life (QOL) and in seizure frequency and severity.

Materials And Methods: Examined group consists of 24 boys and 9 girls. We performed corpus callosotomy, lesionectomy, vagal nerve stimulation, temporal lobectomy and multiple subpial transections.
