REVIEW
W Fenske
Hyponatremia is the most common electrolyte disorder in clinical practice and associated with increased morbidity and mortality, independent of underlying disease. Untreated acute hyponatremia can cause substantial morbidity and mortality as a result of osmotically induced cerebral edema whilst over rapid correction of chronic hyponatremia can cause serious neurologic impairment and death resulting from osmotic demyelination. Still hyponatremia is often neglected and insufficiently addressed, most likely due to limited understanding of its pathophysiological mechanisms...

Early brain injury (EBI) is involved in the process of cerebral tissue damage caused by subarachnoid hemorrhage (SAH), and multiple mechanisms, such as apoptosis and inflammation, participate in its development. Mangiferin (MF), a natural C-glucoside xanthone, has been reported to exert beneficial effects against several types of organ injury by influencing various biological progresses. The current study aimed to investigate the potential of MF to protect against EBI following SAH via histological and biological assessments...

Stimulation of Na(+) /H(+) exchanger isoform 1 (NHE1) in astrocytes causes ionic dysregulation under ischemic conditions. In this study, we created a Nhe1(flox/flox) (Nhe1(f/f) ) mouse line with exon 5 of Nhe1 flanked with two loxP sites and selective ablation of Nhe1 in astrocytes was achieved by crossing Nhe1(f/f) mice with Gfap-Cre(ERT2) Cre-recombinase mice. Gfap-Cre(ERT2+/-) ;Nhe1(f/f) mice at postnatal day 60-90 were treated with either corn oil or tamoxifen (Tam, 75 mg/kg/day, i.p.) for 5 days. After 30 days post-injection, mice underwent transient middle cerebral artery occlusion (tMCAO) to induce ischemic stroke...

Hyponatremia is the most common electrolyte metabolic abnormality in clinical practice. The unfavorable course of many diseases is associated with hyponatremia. Acute severe hyponatremia is life-threatening because cerebral edema may develop. Less obvious chronic hyponatremia increases the risk of balance problems, falls and fractures, especially in elderly patients. In any occasion, hyponatremia should not be now regarded only as a laboratory phenomenon in critically ill patients, but it necessitates a thorough clinical analysis of each individual case and appropriate therapy...

Anoxic encephalopathy is frequently encountered in the medical intensive care unit (ICU). Cerebral edema as a result of anoxic brain injury can result in increased attenuation in the basal cisterns and subarachnoid spaces on computerized tomography (CT) scans of the head. These findings can mimic those seen in acute subarachnoid hemorrhage (SAH) and are referred to as pseudosubarachnoid hemorrhage (pseudo-SAH). Pseudo-SAH is a diagnosis critical care physicians should be aware of as they treat and evaluate their patients with presumed SAH, which is a medical emergency...

BACKGROUND: Gasping is a natural reflex that enhances oxygenation and circulation during cardiopulmonary resuscitation (CPR). OBJECTIVES: This study sought to assess the relationship between gasping during out-of-hospital cardiac arrest and 1-year survival with favorable neurological outcomes. METHODS: The authors prospectively collected incidence of gasping on all evaluable subjects in a multicenter, randomized, controlled, National Institutes of Health-funded out-of-hospital cardiac arrest clinical trial from August 2007 to July 2009...

Background The temporal and anatomical features of vasoconstriction in patients with reversible cerebral vasoconstriction syndrome within hours after symptom onset, in the hyperacute phase, are unclear. Case result Herein we report the cases of two patients with acute severe headache who were diagnosed with reversible cerebral vasoconstriction syndrome. Magnetic resonance imaging within hours after symptom onset revealed multiple areas of isolated cortical vasogenic edema and hyperintense vessel signs of the distal cerebral arteries...

Retinal vein occlusion (RVO) is a common vascular disease of retina; however, the pathomechanism leading to RVO is not yet clear. In general, increasing age, hypertension, arteriosclerosis, diabetes mellitus, dyslipidemia, cardiovascular disorder, and cerebral stroke are systemic risk factors of RVO. However, RVO often occur in the unilateral eye and sometimes develop in young subjects who have no arteriosclerosis. In addition, RVO show different variations on the degrees of severity; some RVO are resolved without any treatment and others develop vision-threatening complications such as macular edema, combined retinal artery occlusion, vitreous hemorrhage, and glaucoma...

The Central nervous system can be affected in extrapulmonary tuberculosis. The intracranial tuberculoma occurrence is a rare entity occurrence; most often occur in the form of discrete small multiple lesions. Rarely a large sized tuberculoma is observed with mass effects and usually managed surgically to provide rapid relief of mass effect, histopathological confirmation of diagnosis, reduction of pathological mass thereby increasing efficacy of medical therapy. Author reports an extremely rare case of giant tuberculoma occurring in a pediatric patient, which was managed with antituberculous medication along with cerebral decongestant...

BACKGROUND: Invasive tests measuring resistance to cerebral spinal fluid (CSF) outflow and the effect of temporary drainage of CSF are used to select candidates affected by idiopathic normal pressure hydrocephalus (iNPH) for shunt surgery. Neither test, however, completely excludes patients from treatment. Perfusion and diffusion magnetic resonance imaging (MRI) are non-invasive techniques that might be of value in selecting patients for surgical treatment and understanding brain changes in iNPH patients...

OBJECTIVE: To investigate free fatty acid levels and histopathologic changes in the brain of rats fed a high fructose diet and to evaluate the effects of Mucuna pruriens, known to have antidiabetic activity, on these changes. MATERIALS AND METHODS: The study comprised of 28 mature female Wistar rats. The rats were divided into four groups, each included 7 rats. Group 1: control; Group 2: fed a high fructose diet (HFrD), Group 3: fed normal rat chow and Mucuna pruriens, and Group 4: fed a high fructose diet and Mucuna pruriens for 6 weeks...

BACKGROUND: To investigate whether prior transient ischemic attack (TIA) had a preconditioning effect on subsequent cerebral infarction in a rat model using middle cerebral artery occlusion (MCAO). METHODS: Thirty-six adult male Sprague-Dawley rats were divided into 3 groups: those with transient (5 minutes) left MCAO (left TIA) (n = 15), those with transient right MCAO (right TIA) (n = 15), and a sham operation group (n = 6). Seven days after the initial transient MCAO, rats in all groups underwent permanent left MCAO...

We report a case of a 39-year-old man presenting with a high-grade left parieto-occipital arteriovenous malformation (AVM) complicated by superior sagittal sinus (SSS) stenosis, seven years after the first presentation. Magnetic resonance imaging revealed a newly developed perilesional edema. Venous sinus stenosis acutely progressed to occlusion and induced multiple intracerebral hemorrhages. An emergent balloon venoplasty of the SSS successfully recanalized the thrombosed sinus. Further, multistage transarterial nidus embolization was performed followed by surgical resection, resulting in a complete eradication of the large AVM...

Ischemia reperfusion injury (IRI) is closely associated with oxidative stress and inflammatory responses. Dracocephalum moldavica L. (DML), a Chinese herbal medicine is known to exert protective effects on myocardial ischemia reperfusion injury in rats by inhibiting oxidation damage and inflammatory reactions. However, the effectiveness of DML in cerebral ischemia reperfusion injury (CIRI) as a protective substance and the underlying mechanisms remain to be determined. The aim of this study was thus to examine the influence of DML on CIRI using a rat model induced by 2-h transient middle cerebral artery occlusion (MCAO) produced by intraluminal suture blockade followed by 22 h reperfusion...

BACKGROUND: Recent data suggest that rapid infusion of intravenous (IV) cold saline for Targeted Temperature Management (TTM) after cardiac arrest is associated with higher rates of rearrest, pulmonary edema, and hypoxia, with no difference in neurologic outcomes or survival when administered by Emergency Medical Services. We sought to determine the effects of IV cold saline administration in the hospital setting in postcardiac arrest patients to achieve TTM and its effect on clinical parameters and neurologic outcomes...
