Diagnostic approach, therapeutic strategies, and surgical indications in intradural thoracic disc herniation associated with CSF leak, intracranial hypotension, and CNS superficial siderosis.

Background And Purpose: Intradural disc herniation (IDH) can manifest with radicular or medullary syndrome. In about 15% of cases, IDH may be responsible, through a dural laceration, for a CSF leak, determining spontaneous intracranial hypotension (SIH) and CNS superficial siderosis (CNSss). This paper attempts to present an overview on IDH as the cause for both CSF leak, and subsequent SIH, and CNSss, and to describe a peculiar clinical and neuroradiological scenario related to this condition.

Patients' reported outcome measures and clinical scales in brain tumor surgery: results from a prospective cohort study.

Background: This study aims to assess surgical outcome in brain tumor surgery using patient reported outcome measures (PROMs) and to compare their results with traditional clinical outcome measurements.

Method: Neuro-oncological patients undergoing surgical removal for the lesion were enrolled; MOCA test, PROMs (EUROHIS-QoL, PGWB-S, WHODAS-12), and the clinical scale Karnofsky Performance Status (KPS) were administered to evaluate respectively cognitive status, quality of life, well-being, disability, and functional status before surgery and at 3-month follow-up. Wilcoxon test was performed to evaluate the longitudinal change of test scores, the smallest detectable difference to classify the change of patients in PROMs, the Cohen kappa to investigate the concordance between KPS and PROMs in classifying the patients' change, and Mann-Whitney U test to compare patients with complications and no complications.

Medial Tentorial Dural Arteriovenous Fistula Embolization: Single Experience with Embolic Liquid Polymer SQUID and Review of the Literature.

Background: Tentorial dural arteriovenous fistulas (DAVFs) are uncommon, complex fistulas located between the leaves of the tentorium cerebelli with a specific anatomic and clinical presentation characterized by high hemorrhagic risk. We present a rare case of a medial tentorial DAVF successfully managed via transarterial embolization using SQUID liquid polymer.

Case Description: A 60-year-old woman presented with a history of left progressive hearing loss and tinnitus for >1 year.

Predicting functional impairment in brain tumor surgery: the Big Five and the Milan Complexity Scale.

OBJECT The Milan Complexity Scale-a new practical grading scale designed to estimate the risk of neurological clinical worsening after performing surgery for tumor removal-is presented. METHODS A retrospective study was conducted on all elective consecutive surgical procedures for tumor resection between January 2012 and December 2014 at the Second Division of Neurosurgery at Fondazione IRCCS Istituto Neurologico Carlo Besta of Milan. A prospective database dedicated to reporting complications and all clinical and radiological data was retrospectively reviewed.

The Impact of Neurosurgical Complications on Patients' Health Status: A Comparison Between Different Grades of Complications.

Objective: The aim of this article is to investigate the frequency of neurosurgical complications according to Landriel-Ibañez Classification and their impact on patients' health status.

Methods: Patients undergoing neurosurgical procedures were enrolled in an observational longitudinal study at Neurological Institute Carlo Besta from January 2012 to September 2013. We evaluated patients' health status before surgery, at discharge, and follow-up with the Karnofsky Performance Status Scale (KPS), whereas the Landriel-Ibañez Classification was used to record complications.

Quality of life, disability, well-being, and coping strategies in patients undergoing neurosurgical procedures: preoperative results in an Italian sample.

Background: The aim of this paper is to present the preliminary results of QoL, well-being, disability, and coping strategies of patients before neurosurgical procedure.

Methods: We analysed data on preoperative quality of life (EUROHIS-QoL), disability (WHODAS-II), well-being (PGWB-S), coping strategies (Brief COPE), and functional status (KPS score) of a sample of patients with brain tumours and cerebrovascular and spinal degenerative disease admitted to Neurological Institute Carlo Besta. Statistical analysis was performed to illustrate the distribution of sociodemographic and clinical data, to compare mean test scores to the respective normative samples, and to investigate the differences between diagnoses, the correlation between tests, and the predictive power of sociodemographic and clinical variables of QoL.

Quality of life measures in Italian neurosurgical patients: validity of the EUROHIS-QOL 8-item index.

Purpose: To assess the validity, reliability and factor structure of the Italian version of the EUROHIS-QOL (European Health Interview Survey-Quality of Life) 8-item index in patients who are potential candidates for neurosurgical procedures.

Methods: Cross-sectional study. Patients completed the EUROHIS-QOL 8-item index, a disability and general well-being questionnaire; the Karnofsky performance status scale (KPS) was used as a general measure of functional status.

Disability in Italian neurosurgical patients: validity of the 12-item World Health Organization Disability Assessment Schedule.

The aim of the study was to assess factor structure, internal consistency and validity of the Italian version of the World Health Organization Disability Assessment Schedule 12-item version (WHODAS-12) in patients scheduled for neurosurgical procedures for brain tumours, cerebrovascular or spinal diseases. Disability was assessed with the WHODAS-12, quality of life with the eight-item European Health Interview Survey-Quality of Life, well-being with the Psychological General Well-Being Index-Short and general health with the Karnofsky Performance Status (KPS) scales. Factor analysis was used to confirm WHODAS-12 one-factor structure; root mean square error of approximation (RMSEA) and χ2/d.

Loss of heterozygosity studies in extracranial metastatic meningiomas.

Although most meningiomas are slow-growing tumours associated with favourable prognosis, they often present local recurrence after surgical treatment; by contrast, extracranial metastatic meningiomas are rare, occurring in less than 1% of the cases. Risk factors for distal spread remain largely unknown. We report three cases with lung or bone metastases from intracranial recurrent meningiomas.
