Lumbar discal cyst and post-operative discal pseudocyst: a case series.

Four cases of lumbar cyst (2 discal cysts and 2 post-operative discal pseudocysts) who presented predominantly with features of sciatica without any motor, sensory or sphincteric disturbances. The patients were treated conservatively, and the management was aimed to avert any untoward surgical intervention taking into consideration patient safety and care. Two had previous lumbar decompressive discectomy.

The Case for Early Antibiotic Commencement and Source Control in Paediatric Subdural Empyema: A Single-Centre Retrospective Case Series.

Background: Subdural empyema is a neurosurgical emergency requiring prompt diagnosis and treatment. There is a debate between the benefits and risks of starting early antibiotics prior to surgical drainage as this is purported to reduce the rate of microbiological diagnosis. Here, we describe our experience of treating this potentially life-threatening condition, advocating for the early commencement of antibiotics and importance of source control in its treatment.

Does Coronavirus Disease 2019 (COVID-19) Affect Perioperative Morbidity and Mortality for Patients Requiring Emergency Instrumented Spinal Surgery? A Single-Center Cohort Study.

Background: The coronavirus disease 2019 (COVID-19) pandemic sent shockwaves through health services worldwide. Resources were reallocated. Patients with COVID-19 still required instrumented spinal surgery for emergencies.

Procalcitonin -Vital Tool to Differentiate Septic Progression of Spondylodiscitis from Drug Hypersensitivity: A Case Report and Brief Review of Literature.

Introduction: Drug hypersensitivity is an important differential diagnosis in patients of infective spondylodiscitis, who develop systemic symptoms such as fever, rash, and arthralgia while on treatment with antibiotics. As these symptoms may also be present in sepsis progression, differentiation between two is very difficult. Procalcitonin (PCT) is one of the important and specific biomarkers of early sepsis.

Craniopharyngioma in children: trends from a third consecutive single-center cohort study.

Objective: The management of children with craniopharyngioma has evolved over time, with a trend toward less invasive neurosurgical approaches as surgeons have sought to balance oncological control and treatment-related morbidity. To this end, the aim of this study was to evaluate the safety and effectiveness of the current management of children with craniopharyngioma compared to the previous management methods used at the authors' treatment center.

Methods: A prospectively maintained database was searched over a 14-year period between January 1, 2005, and December 31, 2018, to identify all children 17 years of age or younger with a new diagnosis of craniopharyngioma.

Subarachnoid haemorrhage with negative initial neurovascular imaging: a systematic review and meta-analysis.

Background: In patients with spontaneous subarachnoid haemorrhage (SAH), a vascular cause for the bleed is not always found on initial investigations. This study aimed to systematically evaluate the delayed investigation strategies and clinical outcomes in these cases, often described as "non-aneurysmal" SAH (naSAH).

Methods: A systematic review was performed in concordance with the PRISMA checklist.

Intraoperative neurophysiological monitoring in paediatric Chiari surgery-help or hindrance?

Introduction: The role of intraoperative neurophysiological monitoring (IONM) during surgery for Chiari I malformation has not been fully elucidated. Questions remain regarding its utility as an adjunct to foramen magnum decompression surgery, specifically, does IONM improve the safety profile of foramen magnum decompression surgery and can IONM parameters help in intraoperative surgical decision-making. This study aimed to describe a single institution experience of IOM during paediatric Chiari I surgery.

Current Surgical Options for Patients with Epilepsy.

Surgery for epilepsy dates back to 1886 and has undergone significant developments. Today it is considered a key treatment modality in patients who are resistant to pharmacological intervention. It improves seizure control, cognition and quality of life.

Novel Surgical Approaches to High-Grade Gliomas.

Treatment of patients with high-grade glioma (HGG) should begin with thorough evaluation by a specialized multidisciplinary team to determine whether or not the patient is appropriate for surgery, chemotherapy and radiotherapy. Particular attention should be paid to the performance status and neurological function. Surgery is the first step in therapeutic intervention.

Patent foramen ovale closure prior to surgery in the sitting position.

Previously, patent foramen ovale (PFO) was an absolute contraindication to surgery in the sitting position. We report two patients with PFO who underwent surgery in the sitting position after percutaneous PFO closure. To our knowledge this is the first report of this technique.

Plurihormonal pituitary adenoma with concomitant adrenocorticotropic hormone (ACTH) and growth hormone (GH) secretion: a report of two cases and review of the literature.

Plurihormonal pituitary adenomas are tumours that show immunoreactivity for more than one hormone that cannot be explained by normal adenohypophysial cytodifferentiation. The most common combinations in these adenomas include growth hormone (GH), prolactin (PRL) and one or more glycoprotein hormone sub-units (β-TSH, β-FSH, β-LH and αSU). The authors report two cases of a plurihormonal pituitary adenoma expressing the rare combination of ACTH and GH.

Pseudotumor cerebri presenting with visual failure in promyelocytic leukemia: a case report.

Introduction: Pseudotumor cerebri secondary to all-trans retinoic acid in acute promyelocytic leukemia is a reported but rare complication of the therapy. Most cases improve following the discontinuation of all-trans retinoic acid. There is no published literature on how to manage such patients if severe symptoms of increased intracranial pressure continue after discontinuation of the drug.

Effective management of severe traumatic brain injury in a district hospital.

The authors investigated how effectively adults with severe traumatic brain injury (TBI) can be managed in a district general hospital intensive care unit offering intracranial pressure monitoring (ICPM) receiving advice from a neurosurgical unit. A single-centre case series with retrospective review of prospectively collected information was undertaken of 44 consecutive patients presenting over seven years from January 2003 to January 2010 with severe traumatic brain injury to a single district general hospital intensive care unit serving a population of 500,000 adults. A prospectively entered clinical database was used to obtain information including patient demographics, Glasgow Coma Score (GCS) on admission, ICPM insertion, ICPM-related complications, inpatient mortality and neurosurgical advice.
