OBJECTIVE: Evidence suggests that reduction of nitric oxide (NO) bioavailability due to oxidative stress plays a central role in the pathophysiology of cerebral vasospasm after subarachnoid haemorrhage (SAH). To prevent SAH-induced cerebral vasospasm, therefore we used nebivolol hydrochloride as a NO-mediated vasodilator and an antioxidant drug in an experimental rat model of SAH. MATERIALS AND METHODS: Forty female Wistar rats were divided into control, SAH, SAH plus placebo, and SAH plus nebivolol groups...

The optimal timing of tracheostomy in patients with traumatic brain injury (TBI) remains unclear. The purpose of this study was to examine the effects of tracheostomy performed within 72 h after admission. In this retrospective cohort study, the authors reviewed the data for a series of 120 consecutive patients who underwent tracheostomy after suffering TBI with an Abbreviated Injury Scale (AIS) score of ≥4. The exclusion criteria were as follows: age <18 years, severe chest injury with an AIS score of ≥4, and a requirement for intubation because of upper airway obstruction...

Spinal tumours in pregnancy are rare. Spinal tumours account for only 10-15% of all primary central nervous system (CNS) tumours. Most spinal tumours in pregnant women have been described as meningiomas or vascular tumours. We present the unique case of a pregnant patient presenting with a CD 99+ primary spinal central PNET.

OBJECTIVE: Acute occlusions of the extracranial internal carotid artery (ICA) and a major intracranial artery respond poorly to intravenous tissue plasminogen activator (tPA) and present an endovascular challenge. The aim of our study was to retrospectively delineate the feasibility of the combined use of emergent carotid stenting and intra-arterial (IA) Abciximab with intracranial revascularization in the setting of acute ischemic stroke and carotid occlusions at our institution. METHODS: Eleven patients with complete cervical carotid occlusion with or without concomitant intracranial ICA and/or MCA occlusion were identified from a single center, retrospective review of patients admitted to the Stroke unit...

OBJECTIVE: Neurotrauma has been labelled as a "silent epidemic" affecting both the developed and the developing nations. To date, no single brain-specific biomarker has been unanimously accepted for routine clinical use in TBI. Our study aims to determine the correlation of "cleaved-tau protein" in severe traumatic brain injury (TBI) with Glasgow Coma Scale (GCS) at the time of admission, mode of injury, CT findings and outcome at discharge. METHODS: The study has been approved by the institutional ethical committee...

OBJECTIVE: Delayed post-traumatic mucoceles are rare. We describe the surgical treatment of a post-traumatic ethmoidal mucocele with intra-orbital extension. METHOD: A uninostril endoscopic endonasal approach (EEA) was performed. The access was contralateral to the lesion to provide a wider lateral view. After a large sphenoid and ethmoid sinuses opening, the collection was drained and the optic nerve precociously identified. The orbital roof was eroded and the frontal dura mater directly visible...

BACKGROUND: Incidental meningiomas are increasingly being diagnosed due to widespread use of brain imaging. Treatment options include surveillance, surgery and stereotactic radiosurgery, but the natural history of these tumours is not fully understood and there are no accepted management guidelines to aid clinical decision-making. The aim of this study was to assess current practice in the United Kingdom and identify areas of variation for further study. METHODS: A questionnaire was distributed to all members of the Society of British Neurosurgeons (SBNS)...

OBJECTIVE: To investigate the outcomes of patients with recurrent/progressive cranial metastases who underwent re-do craniotomy and to assess the utility of surgery as a treatment option. METHODS: A retrospective study was conducted assessing survival after re-do craniotomy for recurrent or progressive cranial metastases. 29 patients were identified between January 2006 and December 2013. Data was gathered from a prospective pathology database, patients' notes and electronic records...

PURPOSE: The relationship between neoplasm and its surrounding vascular structure is essential to the following clinical treatment plan. In this study, 4D computed tomography angiography (4D-CTA) with a wide scan range and dynamic phases of arteriography and venography was used to describe detailed anatomical information for pre-surgical approaches. MATERIALS AND METHODS: From January 2011 to February 2012, we subjected 13 patients with head and neck neoplasms to 4D-CTA...

AIM: To investigate the long term outcomes of microvascular decompression (MVD) for hemifacial spasm (HFS) and to identify any prognostic factors. METHODS: A retrospective analysis of 189 consecutive patients with typical HFS who underwent MVD. Multiple logistic regression analysis of variables at various time points including at least immediate time point and one at no less than six years was performed. RESULTS: Short-term follow-up showed a cure rate of 91%, including 51 cases of delayed resolution (27%)...

A 73-year-old female with a history of metastatic melanoma presented with extensive intracranial subarachnoid haemorrhage. Cranial imaging failed to reveal any vascular anomaly or tumour. MRI of the neuroaxis revealed a melanoma metastasis at T10 with associated subarachnoid haemorrhage. We review the literature on this rare presentation of subarachnoid haemorrhage.

OBJECTIVE: To prospectively compare positron emission tomography-computed tomography (PET-CT) with conventional magnetic resonance imaging (MRI) and FNAC for diagnosis of non- traumatic vertebral lesions fracture in countries like India where tuberculosis is endemic. METHODS: Fifty four patients with non-traumatic spontaneous vertebral lesions were prospectively studied. All patients underwent CEMRI focusing on the spinal lesions, whole-body PET-CT and FNAC.Results were then analysed and compared with final diagnosis obtained either by FNAC or clinical follow up...

Nerve sheath myxomas (NSM) are uncommon benign tumours of nerve sheath origin. These tumours are most often located in the dermis and subcutaneous tissue of the head and neck region, but less frequently can also involve extracutaneous sites but they are rarely seen in the oral cavity. Many authors consider nerve sheath myxoma and neurothekeoma to be variants of the same tumour, though currently it has been demonstrated that both the lesions are distinct entities with different origins and unique morphological features...

BACKGROUND: With the concept of the hybrid operating room gaining popularity, the authors adapted a hybrid angiographic suite with intraoperative computed tomography (iCT) to evaluate accuracy of pedicle screw placement in spinal fusion. This retrospective review examines how well iCT detected extrapedicular screw violation, to then allow repositioning and potentially avoid revision surgery. METHODS: A total of 36 consecutive patients underwent pedicle screw placement in posterior cervical, thoracic, and lumbosacral spinal fusions...

Shunt series (SS) X-rays are often performed as additional routine initial investigations for suspected ventriculo-peritoneal shunt dysfunction, despite low diagnostic utility and radiological implications. We reviewed such referrals at our neurosurgical unit and found an 8.3% sensitivity rate for SS; consistent with current evidence. SS should not be performed routinely.

OBJECTIVE: To improve quality of care for patients presenting with chronic subdural haematoma (CSDH) by introducing a multi-disciplinary integrated care pathway. SUMMARY BACKGROUND: CSDH is a common neurological condition. Incidence rises with age and currently affects around 58/100 000 people over 70 years. Six-month mortality is high (26%), however integrated care pathways have been shown to improve patient outcomes in other surgical subspecialties. MATERIALS AND METHODS: A baseline retrospective audit completed in 2012 identified areas for improvement in patient management...
