Idiopathic systemic capillary leak syndrome (ISCLS) is a rare condition that is characterized by unexplained episodic capillary hyperpermeability due to a shift of fluid and protein from the intravascular to the interstitial space. This results in diffuse general swelling, fetal hypovolemic shock, hypoalbuminemia, and hemoconcentration. Although ISCLS rarely induces cerebral infarction, we expe...

Background and Objective: The S100B protein has recently been considered as an important marker for predicting severe brain damage; however, there has been very little evidence of increasing this marker in cerebral edema due to metabolic disorders such as diabetes ketoacidosis (DKA). This study was designed and performed to evaluate the prognostic role of S100B protein in predicting brain edema...

BACKGROUND AND PURPOSE Brain edema is detrimental in ischemic stroke and its treatment options are limited. Kinins are proinflammatory peptides that are released during tissue injury. The effects of kinins are mediated by 2 different receptors (B1 and B2 receptor [B1R and B2R]) and comprise induction of edema formation and release of proinflammatory mediators. METHODS Focal cerebral ischemia ...

Newly developed colloid volume-expanding agents with mean molecular weights lower than currently available agents may improve outcome after stroke with fewer allergic and coagulation system side effects. The smaller molecule, however, may exacerbate ischemic cerebral edema if it accumulates in areas where ischemia has damaged the blood-brain barrier. We administered low-molecular-weight hydroxy...

Background: Predicting adverse neurovascular complications due to diabetic ketoacidosis (DKA) particularly in children leads to more appropriately management of disease as well as achievement of acceptable patients' survival. Cerebral edema is a life-threatening adverse event following DKA responsible for high mortality rate. Recently, authors have focused introducing new risk assessment tools ...

BACKGROUND Although cerebral occlusive disease leads to cerebral ischemic events, an effective treatment has not yet been established. An ideal therapeutic approach to treat ischemia might have both aspects of enhancement of collateral formation and prevention of neuronal death. Hepatocyte growth factor (HGF) is a potent angiogenic factor that also acts as a neurotrophic factor. Thus, in this s...

Ischemic stroke results in disruption of the blood-brain barrier (BBB), edema formation and neuronal cell loss. Some neuroprotective factors such as vascular endothelial growth factor (VEGF) favor edema formation, while others such as erythropoietin (Epo) can mitigate it. Both factors are controlled by hypoxia inducible transcription factors (HIF) and the activity of prolyl hydroxylase domain p...

The prevention of BBB breakdown and the subsequent vasogenic edema are important parts of the medical management of ischemic stroke. The purpose of this study was to investigate the ischemic tolerance effect of Rosmarinus officinalis leaf hydro-alcoholic extract (RHE). Five groups of animals were designed: sham (underwent surgery without MCAO) and MCAO groups, the MCAO groups were pretreated or...

BACKGROUND Ischemic stroke is often complicated by brain edema, disruption of blood-brain barrier (BBB), and uncontrolled release of arginine-vasopressin (AVP). Conivaptan, a V1a and V2 receptor antagonist, reduces brain edema and minimizes damage to the blood-brain barrier after stroke. Most stroke patients do not receive treatment immediately after the onset of brain ischemia. Delays in thera...

Neurogenic pulmonary edema (NPE) is defined as acute pulmonary edema develops after a significant central nervous system insult. Although NPE has been recognized for a long time, it is still underdiagnosed in clinical practice. The exact mechanism remains unclear, but the activation of sympathetic nervous system and a catecholamine surge play important roles. Common clinical presentations are d...
