Surgically induced brain injury (SBI) results in brain edema and neurological decline. Valproic acid (VA) has been shown to be neuroprotective in several experimental brain diseases. In this study, we investigated the pretreatment effect of VA in a rat model of SBI. A total of 57 male Sprague-Dawley
OBJECTIVE
The aims of this report are to 1) present a rare case of fatal cerebral edema associated with late-onset ornithine transcarbamylase (OTC) deficiency in a juvenile male patient receiving valproic acid and 2) review the neuropathologic changes associated with the hyperammonemia.
METHODS
Case
The aim of this study was to examine whether administration of valproic acid (VPA), a histone deacetylase inhibitor, inhibits proinflammatory mediators and ameliorate visceral vasopermeability both in a rat model of major burn, and also in rat cultured endothelial cells stimulated with permeability
A 79-year-old female was diagnosed with epilepsy because she experienced loss of consciousness twice in January and February and then had a seizure in June 2016. She was treated with 800 mg sodium valproate (sustained release). After 3 days, she experienced loss of appetite, and more than 3 days
Magnetic resonance (MR) multimodality evoked potentials (MEPs) and clinical findings were correlated in a 47-year-old epileptic man in whom parenteral valproic acid (VPA) therapy induced severe comatose hyperammonemic encephalopathy without biological signs of hepatotoxicity (or hepatocytic
Valproic acid (VA) is a major antiepileptic drug, used for several therapeutic indications. It has a wide activity spectrum, reflecting on mechanisms of action that are not fully understood. The objectives of this work were to study the effects of VA on acute models of nociception and inflammation
Pseudo-subarachnoid hemorrhage (PSAH) is a false-positive finding on cranial computed tomography (CT) in patients with cerebral edema. Its appearance on CT resembles subarachnoid hemorrhage despite the absence of subarachnoid blood. We report the finding of PSAH in a case of massive valproic acid
BACKGROUND
Valpromide and sodium divalproate are indicated in the treatment of maniac episodes of bipolar disorder. These drugs are metabolized into valproic acid. The occurrence of peripheral edema has been described as a very rare adverse reaction of those drugs.
METHODS
We report the case of a
In the amphibian Ambystoma mexicanum, valproic acid (VPA) causes retarded development and malformations including neural tube defects. Some of the observed abnormalities resemble exencephaly. We present the light microscopic characteristics of VPA-induced effects on the developing central nervous
OBJECTIVE
To study the protective effects and the related mechanism of valproic acid (VPA) on ischemia-reperfusion-induced injury in retina of rat.
METHODS
Experimental study. Ninety Wistar rats were divided randomly into three groups: normal (blank) control group, retinal ischemia-reperfusion
We report the results of a third retrospective study of the U.S. experience with fatal hepatotoxicity associated with valproic acid (VPA). In the United States, over one million patients received new prescriptions for VPA during the years 1987 to 1993, and 29 patients developed fatal hepatotoxicity.
The aim of this study was to examine whether administration of valproic acid (VPA) improves blood circulation and survival after lethal burn shock. Forty adult male Beagle dogs underwent a 50% TBSA full-thickness flame injury. In the first 24 h after burn, animals were randomly divided into four
Objectives Valproic acid (VPA) is an anticonvulsant used in several clinical scenarios. VPA has been increasingly associated with intentional or unintentional overdose. In patients presenting with severe VPA overdose, supportive care and airway protection are cornerstones of treatment, while
Valproic acid, used alone or in combination with other anticonvulsants in 100 children with epilepsy, improved seizure control in all age groups. Mean improvement in seizure control was 82%. Petit mal seizures responded best, but other types of seizures, even with associated mental and physical
