Neuroscience began with neuroanatomy and neurosurgery in Egypt more than 5000 years ago. Knowledge grew over time and specialized neurosurgery centers were established in north Africa in the eleventh century. However, it was not until the twentieth century that neuroscience research became established in sub-Saharan Africa. In most African countries, clinical research focused on understanding the rationale and improving treatment of epilepsy, infections, nutritional neuropathies, stroke and tumors. Significant advances were made...

BACKGROUND: Venous thromboembolism (VTE) is a serious but preventable cause of morbidity and mortality. Neuromuscular electrical stimulation systems (NMES) for the prevention of VTE may be beneficial for patients in whom pharmacological or standard mechanical prophylaxis methods are contraindicated or are regarded as unsafe or impractical. Although findings of experimental studies suggest that NMES reduce venous stasis, the clinical utility and effectiveness of NMES in VTE prevention remain controversial...

Surgical resection remains the mainstay of treatment for patients with glioma of any grade. Maximal resection of the tumour is central to achieving long-term disease control; however, the relationship between the extent of glioma resection and actual clinical benefit for the patient is predicated on the balance between cytoreduction and neurological morbidity. For the neurosurgical oncologist, the clinical rationale for undertaking increasingly extensive resections has gained traction. In parallel, novel surgical techniques and technologies have been developed that help improve patient outcomes...

Flexible endoscopes have both a wide range of movement and a wide field of view and are thus widely used for endoscopic third ventriculostomy and biopsy. However, tumor resection using flexible endoscopes has scarcely been reported, likely owing to their single port, which has a diameter of 1.2-2.0 mm. Furthermore, flexible endoscopes do not allow some of the basic neurosurgical manipulations, especially sharp dissection with counter tension. Additionally, the position of the forceps and coagulators is fixed within the endoscope...

INTRODUCTION: Neurosurgeons face the highest probability of facing a medical malpractice claim of any specialist. Here, we perform the first specialty-wide review of malpractice claims in neurosurgery using a well-established, national, online legal database. MATERIALS AND METHODS: The Westlaw (Thomson Reuters, New York) legal service was queried for jury verdicts and settlements related to neurosurgery and medical malpractice from 1985 to 2015. Case files were examined and factors recorded included the age and sex of the patient, the state and year in which the verdict was reached, defendant specialties, award payouts, and alleged reasons for malpractice...

Intracranial pressure (ICP) monitoring is now widely used in neurosurgical critical patients. Besides mean ICP value, the ICP derived parameters such as ICP waveform, amplitude of pulse (AMP), the correlation of ICP amplitude and ICP mean (RAP), pressure reactivity index (PRx), ICP and arterial blood pressure (ABP) wave amplitude correlation (IAAC), and so on, can reflect intracranial status, predict prognosis, and can also be used as guidance of proper treatment. However, most of the clinicians focus only on the mean ICP value while ignoring these parameters because of the limitations of the current devices...

Arteriovenious malformations (AVMs) are associated with significant morbidity and mortality, and have a rupture risk of ~3% per year. Treatment of AVMs must be tailored specifically to the lesion, with surgical resection being the gold standard for small, accessible lesions. Pre-operative embolization of AVMs can reduce nidal blood flow and remove high-risk AVM features such as intranidal or venous aneurysms, thereby simplifying a challenging neurosurgical procedure. Herein, we describe our approach for the staged endovascular embolization and open resection of AVMs, and highlight the advantages of having a comprehensively trained neurovascular surgeon leading a multi-disciplinary clinical team...

For dural arteriovenous fistula (DAVF), when the usual endovascular or neurosurgical approaches are difficult to treat, multi-modal treatment can be helpful. We present a case of a 71-year-old woman with DAVF, who presented with an intracerebral haemorrhage. Digital subtraction angiography revealed a DAVF of the transverse sinus, with cortical venous reflux. Transvenous and transarterial approaches for coil embolization failed. In the operating room, a small craniotomy was performed, and coil embolization was done under fluoroscopy...

Large lobar intracerebral hemorrhages (ICHs) can cause rapid neurological deterioration, and affected patients have low rates of survival and functional independence. Currently, the role of surgical intervention in the management patients with lobar ICHs is controversial. Minimally invasive technologies have been developed which may potentially decrease the operative morbidity of ICH surgery. The aim of this case report is to describe the technical aspects of the use of a novel minimally invasive endoport system, the BrainPath (NICO, Indianapolis, IN, USA), through an eyebrow incision for evacuation of a large lobar hematoma...

The paper presents the use of shape memory alloy (SMA) spring actuators with real-time cooling to control the motion of the MINIR-II robot. A new actuation mechanism involving the passage of water as the cooling medium and air as the medium to drive out the water has been developed to facilitate real-time control of the springs. Control parameters, such as current, water flow rates, SMA pre-displacement, and gauge pressure of the compressed air, are identified from the SMA thermal model and from the actuation mechanism...

INTRODUCTION: Decompressive craniectomy (DC) is a lifesaving procedure but is associated to several post-operative complications, namely cerebrospinal fluid (CSF) dynamics impairment. The aim of this multicentric study was to evaluate the incidence of such CSF alterations after DC and review their impact on the overall outcome. MATERIAL AND METHODS: We performed a retrospective multicentric study to analyze the CSF disorders occurring in children aged from 0 to 17 years who had undergone a DC for traumatic brain injury (TBI) in the major Departments of Pediatric Neurosurgery of France between January 2006 and August 2016...

Diagnosis of a brain tumour is associated with a tremendous disruption of emotional, physical and social well-being. Due to the complexity of the disease and the affection of the central organ, the brain, brain tumour patients differ from other cancer patients. The purpose of this study was to evaluate the concerns and burdens presented by brain tumour patients during their initial psycho-oncological consultation. We performed a retrospective analysis of 53 patients with the diagnosis of either benign or malignant brain tumour, seeking counsel by a neurosurgeon specialised in psycho-oncology...

The purpose of this study was to review our experience with a single case of mastoiditis associated with sigmoid sinus thrombosis and increased intracranial pressure, and to review the experience of others through prior publications. We reviewed a case of a 6-year-old boy with an acute otitis media and mastoiditis, with associated ipsilateral sigmoid sinus and contralateral distal transverse sinus thrombosis. Based on the literature and our own experience, we conclude that most children with dural sinus thrombosis from acute otitis media and mastoiditis, in the setting of increased intracranial pressure, attain a good neurological outcome with a conservative neurosurgical approach...

Emotions involve many cortical and subcortical regions, prominently including the amygdala. It remains unknown how these multiple network components interact, and it remains unknown how they cause the behavioral, autonomic, and experiential effects of emotions. Here we describe a framework for combining a novel technique, concurrent electrical stimulation with fMRI (es-fMRI), together with a novel analysis, inferring causal structure from fMRI data (causal discovery). We outline a research program for investigating human emotion with these new tools, and provide initial findings from two large resting-state datasets as well as case studies in neurosurgical patients with electrical stimulation of the amygdala...

RATIONALE: Asympotamic syringomyelia accompanied with metastatic cerebellar and thoracic spinal intramedullary lymphoma is rare in clinical practice. If the intramedullary lymphoma is large enough, the patient will rapidly develop neurologic signs of spinal injury. The prognosis of this type of complication is always bad. PATIENT CONCERNS: Rapid and correct diagnosis and treatment is important for metastatic extranodal lymphoma with B cell of origin. DIAGNOSES: Syringomyelia accompanied with metastatic cerebellar and thoracic spinal intramedullary lymphoma...

BACKGROUND: We recently described the genotype/phenotype features of all Spanish patients diagnosed with McArdle disease as of January 2011 (n = 239, prevalence of ~1/167,000) (J Neurol Neurosurg Psychiatry 2012;83:322-8). Several caveats were however identified suggesting that the prevalence of the disease is actually higher. METHODS: We have now updated main genotype/phenotype data, as well as potential associations within/between them, of all Spanish individuals currently diagnosed with McArdle disease (December 2016)...
