Skull Base Chordoma and Chondrosarcoma: Neuroradiologist's Guide to Diagnosis, Surgical Management, and Proton Beam Therapy.

Skull base chordomas and chondrosarcomas are distinct types of rare, locally aggressive mesenchymal tumors that share key principles of imaging investigation and multidisciplinary care. Maximal safe surgical resection is the treatment choice for each, often via an expanded endoscopic endonasal approach, with or without multilayer skull base repair. Postoperative adjuvant radiation therapy is frequently administered, usually with particle therapy such as proton beam therapy (PBT).

Protocol for the development of a multidisciplinary clinical practice guideline for the care of patients with chronic subdural haematoma.

A common neurosurgical condition, chronic subdural haematoma (cSDH) typically affects older people with other underlying health conditions. The care of this potentially vulnerable cohort is often, however, fragmented and suboptimal. In other complex conditions, multidisciplinary guidelines have transformed patient experience and outcomes, but no such framework exists for cSDH.

Retrospective Review of Surgical Site Infections after Endoscopic Endonasal Sellar and Parasellar Surgery: Multicenter Quality Data from the North American Skull Base Society.

 Transnasal access to the anterior skull base provides a minimally invasive approach for sellar and parasellar masses compared with its open counterparts. The unique microbiome of the sinonasal mucosa provides distinct challenges not encountered with other cranial approaches. The use of antibiotics in these cases has not been standardized, and data remain scarce regarding infectious outcomes.

Translabyrinthine resection of NF2 associated vestibular schwannoma with cochlear implant insertion.

The authors present the case of a 24-year-old female with neurofibromatosis type 2. Growth of the left vestibular schwannoma and progressive hearing loss prompted the decision to proceed to translabyrinthine resection with cochlear nerve preservation and cochlear implant insertion. Complete resection with preservation of the facial and cochlear nerves was achieved.

Management evaluation of metastasis in the brain (MEMBRAIN)-a United Kingdom and Ireland prospective, multicenter observational study.

Background: In recent years an increasing number of patients with cerebral metastasis (CM) have been referred to the neuro-oncology multidisciplinary team (NMDT). Our aim was to obtain a national picture of CM referrals to assess referral volume and quality and factors affecting NMDT decision making.

Methods: A prospective multicenter cohort study including all adult patients referred to NMDT with 1 or more CM was conducted.

Drains result in greater reduction of subdural width and midline shift in burr hole evacuation of chronic subdural haematoma.

Background: Drain insertion following chronic subdural haematoma (CSDH) evacuation reduces recurrence and improves outcomes. The mechanism of this improvement is uncertain. We assessed whether drains result in improved postoperative imaging, and which radiological factors are associated with recurrence and functional outcome.

Time to surgery following chronic subdural hematoma: post hoc analysis of a prospective cohort study.

Background: Chronic subdural hematoma (CSDH) is a common neurological condition; surgical evacuation is the mainstay of treatment for symptomatic patients. No clear evidence exists regarding the impact of timing of surgery on outcomes. We investigated factors influencing time to surgery and its impact on outcomes of interest.

Does Drain Position and Duration Influence Outcomes in Patients Undergoing Burr-Hole Evacuation of Chronic Subdural Hematoma? Lessons from a UK Multicenter Prospective Cohort Study.

Background: Drain insertion following chronic subdural hematoma (CSDH) evacuation improves patient outcomes.

Objective: To examine whether this is influenced by variation in drain location, positioning or duration of placement.

Methods: We performed a subgroup analysis of a previously reported multicenter, prospective cohort study of CSDH patients performed between May 2013 and January 2014.

Global hydrocephalus epidemiology and incidence: systematic review and meta-analysis.

Objective: Hydrocephalus is one of the most common brain disorders, yet a reliable assessment of the global burden of disease is lacking. The authors sought a reliable estimate of the prevalence and annual incidence of hydrocephalus worldwide.

Methods: The authors performed a systematic literature review and meta-analysis to estimate the incidence of congenital hydrocephalus by WHO region and World Bank income level using the MEDLINE/PubMed and Cochrane Database of Systematic Reviews databases.

Outcomes following surgery in subgroups of comatose and very elderly patients with chronic subdural hematoma.

Increasing age and lower pre-operative Glasgow coma score (GCS) are associated with worse outcome after surgery for chronic subdural haematoma (CSDH). Only few studies have quantified outcomes specific to the very elderly or comatose patients. We aim to examine surgical outcomes in these patient groups.

Prospective, multicentre study of external ventricular drainage-related infections in the UK and Ireland.

Objectives: External ventricular drain (EVD) insertion is a common neurosurgical procedure. EVD-related infection (ERI) is a major complication that can lead to morbidity and mortality. In this study, we aimed to establish a national ERI rate in the UK and Ireland and determine key factors influencing the infection risk.

Spinal cord stimulation during the antepartum and intrapartum periods: a case report showing no deleterious effect of conventional paraesthesia producing stimulation.

We report on a 25-year-old woman who used her spinal cord stimulator (SCS), previously inserted for chronic regional pain syndrome (CPRS), to assist with both chronic and pregnancy-related pain management. We describe the therapeutic effect of the stimulator and briefly highlight the issues surrounding the use of SCS during pregnancy.

Outcomes of endovascular aneurysm repair with 2 different endograft systems with suprarenal fixation in patients with hostile infrarenal aortic anatomy.

Objective: To evaluate 2 different aortic endograft systems with suprarenal fixation in patients with unfavorable neck morphology.

Methods: A prospective observational study assigning patients with abdominal aortic aneurysm with unfriendly neck anatomy treated with 2 different endograft systems (Endurant and Zenith) was conducted. The log-rank test was applied to investigate the differences in cumulative outcome parameters.
