BACKGROUND: Optic nerve sheath diameter (ONSD) evaluated in CT imaging as well as Rotterdam CT Score (RCTS) are proven independent predictors of outcome in patients with traumatic brain injury (TBI). To date, no study has correlated ONSD on admission CT scan with RCTS. MATERIAL/METHODS: Retrospective cohort study comprised of consecutive patients undergoing CT imaging for traumatic brain injury recruited between January and October 2015. Bilateral ONSD was measured 3 mm behind the eyeball in axial and sagittal planes and mean value was calculated...

AIM: Disturbances in brain function and development may play a role in sudden infant death syndrome (SIDS). This Norwegian study aimed to test the hypothesis that specific variants of genes involved in water transport and potassium homeostasis would be predisposing factors for SIDS. METHODS: Genetic variation in the genes encoding aquaporin-4 (AQP4), Kir4.1 (KCNJ10) and α-syntrophin were analysed in 171 SIDS cases (62.6% male) with a median age of 15.5 (2-52) weeks and 398 adult controls (70...

A 54-year-old man presented with two episodes of dysarthria and left facial droop. Both episodes resolved by the time of examination. MRI of the brain revealed a right frontotemporal, heterogeneously enhancing mass with surrounding vasogenic oedema, suggestive of a high-grade primary brain neoplasm. The patient was administered preoperative 5-aminolevulinic acid hydrochloride (Gliolan), and fluorescence-guided resection of the lesion was undertaken. Cryptococcus gattii infection was diagnosed from the specimen and the patient was given appropriate antifungal treatment...

Stroke is the second leading cause of death worldwide, affecting about 240 people a day in South Africa and leaving survivors with residual disabilities. At the moment, there is no clinically approved neuroprotective product for stroke but the consumption of plant polyphenols has been suggested to offer some protection against stroke. In this study, we investigated the effects of long-term consumption of fermented rooibos herbal tea (FRHT) on ischemia/reperfusion (I/R)-induced brain injury in adult male Wistar rats...

Mild hypothermia improves survival and neurological recovery after cardiac arrest (CA) and cardiopulmonary resuscitation (CPR). However, the mechanism underlying this phenomenon is not fully elucidated. The aim of this study was to determine whether mild hypothermia alleviates early blood-brain barrier (BBB) disruption. We investigated the effects of mild hypothermia on neurologic outcome, survival rate, brain water content, BBB permeability and changes in tight junctions (TJs) and adherens junctions (AJs) after CA and CPR...

Cerebral venous sinus thrombosis (CVST) is common in Asians, accounting for 15% of all strokes in the young. CVST causing malignant cerebral oedema with brain herniation and death are referred as malignant CVST. This study was aimed at evaluating the outcome of patients and factors predicting the outcome with malignant CVST after decompressive surgery. It was a retrospective, observational, single centre, hospital-based and cross-sectional study. Records of patients with malignant CVST who had decompressive surgery were analysed...

Vascular cognitive impairment and dementia (VCID) include a wide spectrum of chronic manifestations of vascular disease related to large vessel strokes and small vessel disease (SVD). Lacunar strokes and white matter (WM) injury are consequences of SVD. The main vascular risk factor for SVD is brain hypoperfusion from cerebral blood vessel narrowing due to chronic hypertension. The hypoperfusion leads to activation and degeneration of astrocytes with the resulting fibrosis of the extracellular matrix (ECM)...

Posterior reversible encephalopathy syndrome (PRES) is a clinical and radiological condition with diverse neurological manifestations. Many clinical factors are known causes of PRES, but only a few cases of PRES have been reported in patients with chronic kidney disease (CKD) and infectious disease. We describe three cases of PRES in patients with CKD triggered by various infectious diseases. Characteristic hyperintense signals on magnetic resonance imaging (MRI) indicating reversible vasogenic brain oedema in various parts of the brain were observed...

Because ischaemic stroke is one of the most common brain disorders, diverse effective therapies are urgently required. Recent studies reported a variety of azetidine-based scaffolds for the development of central nervous system-focused lead-like libraries. However, their mechanisms of action and in vivo functions remain unclear. Here, we investigated the potential mechanism and beneficial effects of 3-(naphthalen-2-yl(propoxy)methyl)azetidine hydrochloride (KHG26792), a novel azetidine derivative, on ischaemia/reperfusion (I/R) brain injury...

INTRODUCTION: Worldwide, traumatic casualties are projected to exceed 8 million by year 2020. Haemorrhagic shock and brain injury are the leading causes of death following trauma. While intravenous fluids have traditionally been used to support organ perfusion in the setting of haemorrhage, recent investigations have suggested that restricting fluid therapy by tolerating more severe hypotension may improve survival. However, the safety of permissive hypotension remains uncertain, particularly among patients who have suffered a traumatic brain injury...

PRES is a neurological syndrome characterised by reversible subcortical vasogenic brain oedema in patients with acute neurological signs and symptoms. It occurs in the context of fluctuations in blood pressure, renal failure, autoimmune disorders, eclamptic syndromes and with use of cytotoxic drugs. We present the case of a 60year old female with advanced bowel cancer who was admitted with seizures and sub-arachnoid haemorrhage, with radiographic features of PRES, shortly after receiving bevacizumab (Avastin), a VEGF-inhibitor...

We describe a case of a man aged 41 years who presented with a history of generalised headaches for 1 week and an acute episode of tonic-clonic seizures. He had no history of medical illness, was non-smoker, with an extensive family history of haematological disorders. Initial CT brain with contrast did not show any abnormalities in brain parenchyma. X-ray and CT right shoulder showed shoulder dislocation secondary to trauma associated with seizure prior to hospital admission. Subsequently, MRA and MRV brain was arranged, which revealed extensive expansible occlusive filling defect dominating the middle of superior sagittal sinus with left frontal cortical and subcortical acute oedema...

OBJECTIVES: Matrix metalloproteinase-9 (MMP-9) is an inducible metalloproteinase that can degrade the cerebrovascular matrix leading to disruption of the blood-brain barrier and exacerbation of oedema in neurotrauma. Therefore, our aim was to determine whether MMP-9 plasma levels were associated with intensive care unit (ICU) mortality after severe traumatic brain injury (TBI) despite the presence of extracerebral injuries. METHODS: This cohort enrolled 80 patients who suffered severe TBI (Glasgow Coma Scale: 3-8 at hospital admission)...

Diffusion-weighted imaging provides image contrast that is different from that provided by conventional magnetic resonance imaging techniques. It is highly sensitive for detection of cytotoxic oedema, and as such has gained favor in the detection of acute infarcts. However, diffusion-weighted imaging is underrepresented in the characterisation of many other disease processes. Our objective is to differentiate diseases that manifest with various neurological disorders, based on diffusion contrast and apparent diffusion coefficient values and review of hyper- and hypointense lesions on diffusion-weighted imaging...
