BACKGROUND: Gamma-Knife radiosurgery (GKS) can be the treatment of choice for small cerebral Arteriovenous Malformations (AVMs) in eloquent brain areas or, in association with endovascular treatment, for large and complex AVMs. Among the possible delayed complications occurring after radiosurgery of AVMs, de novo formation of a cavernoma has only recently been described. The Authors report a unique case of communicating hydrocephalus with highly proteinaceous cerebrospinal fluid (CSF) due to a cavernoma-like lesion of an obliterated cerebral AVM treated by embolizaton and radiosurgery...

INTRODUCTION: Postmortem evaluations of cerebral edema typically involve examinations of macroscopic features such as the presence of pressure signs and compression of the ventricles. Global massive edema is easily detectable in an autopsy, but less-extensive edema may be difficult to diagnose. AIM: The aim of this study was to compare measurements of brain water contents, postmortem CT radiodensity and brain weight to skull size in edematous and nonedematous brains in order to develop an objective method for postmortem evaluations of brain edema...

BACKGROUND: Brain metastases (BMs) are the most frequent malignancy of the central nervous system. Previous research suggested that some metastases show infiltrative behavior rather than sharp demarcation. We hypothesized that three magnetic resonance (MR) imaging parameters-(a) tumor size, (b) extent of peritumoral edema, and (c) presence of multiple BMs-are predictors of cellular invasion beyond the surgically identifiable tumor margins. METHODS: We performed a post hoc analysis on prospectively collected data of patients with BMs...

Background: Epigastric pain, vomiting, and other gastrointestinal problems are among the most important symptoms of malaria infection as they suggest the possibility that the condition is serious. Pathophysiologies such as gastric mucosal changes and delayed gastric emptying have been reported in serious cases of malaria infection. However, it is unclear whether or not pathophysiological involvement of the upper gastrointestinal tract occurs in Plasmodium berghei ANKA (PbA)-infected mice...

Two cats were presented with multifocal neurological signs. One cat's signs progressed over 2 wk; the other cat progressed over 5 days. Examinations were consistent with a process involving the prosencephalon, vestibular system, and general proprioceptive/upper motor neuron systems. MRI of the brain and cervical spinal cord reveal widespread T2 hyperintensity of the white matter. Affected areas included the cerebrum, cerebral peduncles, corticospinal tracts of the pons and medulla, and the cerebellum. T2 hyperintensity was present in all funiculi of the spinal cord...

Background and Purpose- Global cerebral edema occurs in up to 57% of patients with subarachnoid hemorrhage (SAH) and is associated with prolonged hospital stay and poor outcome. Recently, admission brain edema was successfully graded using a simplified computed tomography-based semiquantitative score (subarachnoid hemorrhage early brain edema score [SEBES]). Longitudinal evaluation of the SEBES grade may discriminate patients with rapid and delayed edema resolution after SAH. Here, we aimed to describe the resolution of brain edema and to study the relationship between this radiographic biomarker and hospital course and outcome after SAH...

Tight junctions (TJs) serve an important role in maintaining the integrity of the blood-brain barrier (BBB), while neurological disorders, including ischemic stroke, induce TJ disruption and increase BBB permeability; results include edema formation and hemorrhage transformation. Cerebral endothelium protection presents a promising approach in ischemic stroke therapy. In the current study, protective effects of the epidermal growth factor (EGF) on ischemia-induced disruption of BBB integrity were examined using an oxygen-glucose deprivation (OGD) model in bEnd3 cells...

BACKGROUND: Abusive head trauma (AHT) peaks during early infancy and decreases in toddler years. Infants and toddlers experience different injuries, possibly impacting the risk of mortality. We aimed to evaluate the association of age with mortality METHODS: We conducted a retrospective study of AHT hospitalizations in 2000, 2003, 2006, 2009, and 2012 from the Kid's Inpatient Claims Database (KID). An accidental head trauma cohort was included to hypothesize that the association between age and mortality is unique to abuse...

BACKGROUND: Glibenclamide is a widely used sulfonylurea drug prescribed to treat type II diabetes mellitus. Previous studies have demonstrated that glibenclamide has neuroprotective effects in central nervous system injury. However, the exact mechanism by which glibenclamide acts on the blood-brain barrier (BBB) after intracerebral hemorrhage (ICH) remains unclear. The purpose of this study was to validate the neuroprotective effects of glibenclamide on ICH and to explore the mechanisms underlying these effects...

BACKGROUND Intracerebral hemorrhage (ICH) is associated with inflammation and disruption of the blood-brain barrier (BBB). Lipoxin A4 methyl ester (LXA4 ME), is a stable synthetic analog of lipoxin with anti-inflammatory properties. This study aimed to investigate the effects of LXA4 ME in a rat model of ICH. MATERIAL AND METHODS Male Sprague-Dawley rats (n=120), between 12-13 weeks of age, were divided into the sham group (sham-operated), the vehicle-treated group (ICH+vehicle), the LXA4 ME-L group (ICH+low-dose LXA4 ME, 10 ng/d), and the LXA4 ME-H group (ICH+high-dose LXA4 ME, 100 ng/d)...

Subarachnoid hemorrhage (SAH) is a devastating cerebrovascular event that often is followed by permanent brain impairments. It is necessary to explore the pathogenesis of secondary pathological damages in order to find effective interventions for improving the prognosis of SAH. Blockage of brain lymphatic drainage has been shown to worsen cerebral ischemia and edema after acute SAH. However, whether or not there is persistent dysfunction of cerebral lymphatic drainage following SAH remains unclear. In this study, autologous blood was injected into the cisterna magna of mice to establish SAH model...

Protocatechuic acid (PCA) has been well studied for its neuroprotection value in several diseases, but the effect in intracerebral hemorrhage (ICH) has not been reported. Here we verified the protection of PCA in ICH, and investigated the relative mechanisms. ICH model mice were established by injection of collagenase IV. The mice were treated with PCA once per day for 3 days, starting immediately after operation. The modified neurological severity score (mNSS) of mice at 1st , 3rd and 7th day after operation were recorded...

There is little information in the literature on the safety of reascent to high altitude shortly after resolution of severe acute altitude illness, including high altitude pulmonary or cerebral edema. We present a case of a 52-y-old male climber who was diagnosed with high altitude pulmonary edema during the 2018 Everest spring climbing season, descended to low altitude for 9 d, received treatment, and returned to continue climbing with a very rapid ascent rate. Despite a very recent history of high altitude pulmonary edema and not using pharmacologic prophylaxis over a very rapid reascent profile, the climber successfully summited Mt...

Cerebral edema and elevated intracranial pressure (ICP) are common complications of acute brain injury. Hypertonic solutions are routinely used in acute brain injury as effective osmotic agents to lower ICP by increasing the extracellular fluid tonicity. Acute kidney injury in a patient with traumatic brain injury and elevated ICP requiring renal replacement therapy represents a significant therapeutic challenge due to an increased risk of cerebral edema associated with intermittent conventional hemodialysis...
