Objective: The objective of this study was to examine the level of daily impairment in adult patients suffering from craniopharyngioma.

Postoperative Nausea and Vomiting Following Craniotomy: Risk Factors and Complications in Context of Perioperative High-dose Dexamethasone Application.

Introduction:  Postoperative nausea and vomiting (PONV) is common in patients after craniotomy and may lead to severe postoperative complications. The aim of this study was to identify risk factors and postoperative complications associated with PONV in the context of perioperative high-dose dexamethasone administration.

Patients And Methods:  In this prospective single-center study, all patients planned for elective craniotomy for supra- and infratentorial lesions were eligible to be included.

Seizures as presenting symptom in patients with glioblastoma.

Objective: The clinical course and underlying molecular causes in patients with glioblastoma presenting with seizures are poorly understood. Here we investigated clinical features and carrier systems as well as a transaminase relevant in glutamate homeostasis in patients with glioblastoma.

Methods: We performed a retrospective analysis of our clinical glioma database for clinical data during a 2-year period.

Intraocular pressure during neurosurgical procedures in context of head position and loss of cerebrospinal fluid.

Objective: Perioperative visual loss (POVL) is a rare but serious complication in surgical disciplines, especially in spine surgery. The exact pathophysiology of POVL remains unclear, but elevated intraocular pressure (IOP) is known to be part of it. As POVL is rarely described in patients undergoing intracranial or intradural surgery, the aim of this study was to investigate the course of IOP during neurosurgical procedures with opening of the dura mater and loss of CSF.

Extensive Spinal Adhesive Arachnoiditis After Extradural Spinal Infection-Spinal Dura Mater Is No Barrier to Inflammation.

Background: Spinal adhesive arachnoiditis (SAA) is an inflammatory process of the meninges. Cystic changes and cicatrization may lead to neurologic deficits and immobilization. Therapy is difficult and often unsatisfactory.

Surgical treatment of spinal metastases from renal cell carcinoma-effects of preoperative embolization on intraoperative blood loss.

The objective of this paper is analyzing the effects of preoperative embolization on intraoperative blood loss in spinal surgery for renal cell carcinoma (RCC) metastasis and identifying factors contributing to an increased blood loss in the surgical procedure. A retrospective analysis was performed in patients who were treated in for spinal metastasis from RCC between 2011 and 2016. Factors analyzed were reduction of tumor blush, timing of embolization, selective vs.

Somatosensory evoked potentials in patients with high-grade aneurysmal subarachnoid hemorrhage.

OBJECTIVE The aim of this prospective study was to investigate the value of somatosensory evoked potentials (SEPs) in predicting outcome in patients with high-grade aneurysmal subarachnoid hemorrhage (SAH). METHODS Between January 2013 and January 2015, 48 patients with high-grade SAH (Hunt and Hess Grade III, IV, or V) who were admitted within 3 days after hemorrhage were enrolled in the study. Right and left median and tibial nerve SEPs were recorded on Day 3 after hemorrhage and recorded again 2 weeks later.

Prognostic Value of Early S100 Calcium Binding Protein B and Neuron-Specific Enolase in Patients with Poor-Grade Aneurysmal Subarachnoid Hemorrhage: A Pilot Study.

Background: This prospective study was undertaken to investigate the value of early S100 calcium binding protein B (S100B) and neuron-specific enolase (NSE) in prognosticating outcome in patients with poor-grade aneurysmal subarachnoid hemorrhage and to develop a statistical model and cutoff values for clinical practice.

Methods: Between 2012 and 2014, patients with poor-grade subarachnoid hemorrhage (Hunt and Hess grade 3-5) who were admitted within 24 hours after hemorrhage were prospectively enrolled. Serum NSE and S100B levels were assayed once daily during the first 3 days after hemorrhage.

Pituicytoma-An outlook on possible targeted therapies.

Introduction: Pituicytoma is a rare neoplasm of the sella region. Tumor resection is the primary treatment option, but remains subtotal due to excessive bleeding in many cases. The search for alternative or additional treatment regimens is necessary.

Cage deviation in the subaxial cervical spine in relation to implant position in the sagittal plane.

Subsidence of interbody cages is a frequently observed and relevant complication in anterior cervical discectomy and fusion (ACDF). Only a handful of studies concentrated on the modality of subsidence and its clinical impact. We performed a retrospective analysis of ACDF patients from 2004 to 2010.

Impact of spinal cord compression from intradural and epidural spinal tumors on perioperative symptoms-implications for surgical decision making.

Spinal cord or cauda equina compression (SCC) is an increasing challenge in clinical oncology due to a higher prevalence of long-term cancer survivors. Our aim was to determine the clinical relevance of SCC regarding patient outcome depending on different tumor entities and their anatomical localization (extradural/intradural/intramedullary). We retrospectively analyzed 230 patients surgically treated for SCC.

Intramedullary spinal cord metastases: an increasingly common diagnosis.

OBJECT Intramedullary spinal cord metastases (ISCM) represent a small proportion of intramedullary tumors. However, with the lifespans of patients with malignant tumors increasing, incidents of ISCM are on the rise. Due to threateningly severe disabilities in patients, accompanied by limited life expectancy, every attempt should be made to treat these tumors the same way as metastases elsewhere in the CNS, with the goal of complete removal of the ISCM and preservation of neurological functions.

Minimally invasive approach for small ventrally located intradural lesions of the craniovertebral junction.

Object: The surgical management of lesions ventral to the neuraxis at the level of the craniovertebral junction (CVJ) and upper cervical spine is challenging. Here, the authors describe a minimally invasive dorsal approach for small ventrally located intradural lesions at the CVJ as an alternative for the more extensive classic transoral approach or variants of suboccipital approaches.

Methods: Between 2012 and 2014, 6 symptomatic patients with a small lesion of the ventral aspect at the CVJ level were treated using a minimally invasive dorsal approach at the University Medical Center in Hamburg-Eppendorf, Germany.
