Microglia, the resident immune cells of the brain, perform elaborate surveillance in which they physically interact with neuronal elements. A novel form of microglia-neuron interaction named microglial process convergence (MPC) toward neuronal axons and dendrites has recently been described. However, the molecular regulators and pathological relevance of MPC have not been explored. Here, using high-resolution two-photon imaging in vivo and ex vivo, we observed a dramatic increase in MPCs after kainic acid- or pilocarpine-induced experimental seizures that was reconstituted after glutamate treatment in slices from mice...

Cefepime-induced encephalopathy including nonconvulsive status epilepticus has been known to develop in the patients with renal impairment. However, we report a 74-year-old woman with normal renal function who developed stuporous mental status during cefepime administration. Electroencephalogram (EEG) revealed 2 Hz rhythmic sharp-and-waves continuously, which suggested nonconvulsive status epilepticus (NCSE). After cefepime discontinuation, clinical symptoms recovered gradually and EEG findings showed only background slowing without epileptiform discharges...

BACKGROUND AND PURPOSE: Status epilepticus (SE) is a neurological disorder with high prevalence and mortality rates, requiring immediate intervention. Licofelone is a cyclooxygenase (COX) and 5-lipoxygenase (5-LOX) inhibitor, which its effectiveness to treat osteoarthritis has been approved. Increasing evidence suggests an involvement of COX and LOX enzymes in epileptic disorders. Thus, in the present study we investigate possible effects of licofelone on prevention and termination of SE...

Anti-N-methyl-d-aspartate-receptor (NMDAR) encephalitis is an uncommon autoimmune disorder with a wide spectrum of neuropsychiatric symptoms. There is a great requirement to emphasize the importance of a multidisciplinary team approach in the process of diagnosis and treatment of the potentially fatal condition, including psychiatrists, neurologists, gynaecologists and intensivists. Physicians must be aware that psychiatric and neurological disorders, which are typical features for NMDAR encephalitis in young women with ovarian tumours, may progress into status epilepticus and respiratory insufficiency...

The study reports a girl with pyridoxine-dependent epilepsy. The girl was admitted at the age of 2 years because of intermittent convulsions for 1.5 years and psychomotor retardation. She had a history of "hypoxia" in the neonatal period. At the age of 5 months recurrent epileptic seizures occurred. The child was resistant to antiepileptic drugs, and had many more seizures when she got cold or fever. She also had a lot of convulsive status epilepticus. No discharges were found during several video-EEG monitorings...

BACKGROUND: Rapid sequence intubation and emergency intubation in the emergency department (ED) can be life-saving procedures, but require the appropriate skills, experience and preparation to avoid complications ranging from simple trauma to life-threatening desaturation. Only scarce data exist in the published literature on complications following emergency intubation in children and most guidelines are extrapolated from the adult population. PATIENTS AND METHODS: We reviewed all emergency intubations of patients in our tertiary paediatric ED within a 2-year period to estimate the incidence of complications and to analyse the risk factors associated with this procedure...

The increasing number of treatment options and the high costs associated with epilepsy have fostered the development of economic evaluations in epilepsy. It is important to examine the availability and quality of these economic evaluations and to identify potential research gaps. As well as looking at both pharmacologic (antiepileptic drugs [AEDs]) and nonpharmacologic (e.g., epilepsy surgery, ketogenic diet, vagus nerve stimulation) therapies, this review examines the methodologic quality of the full economic evaluations included...

OBJECTIVE: Hydrogen sulfide (H2S), as a novel gasotransmitter, plays important roles in a number of physiological and pathological processes. Its effectiveness has been demonstrated in different types of brain disorders but not in repetitive febrile seizure (febrile status epilepticus; FSE) models. This study aims to test whether a donor of H2S sodium sulfhydrate (NaHS) is also effective for FSE in rats. METHODS: FSE was induced in rat pups on postnatal day 10 in water at 45...

BACKGROUND: In the diagnosis of nonconvulsive status epilepticus (NCSE), capture of ongoing ictal electroencephalographic (EEG) findings is the gold standard; however, this is practically difficult without continuous EEG monitoring facilities. Magnetic resonance imaging (MRI), including diffusion-weighted imaging (DWI) and perfusion MRI with arterial spin labeling (ASL), have been applied mainly in emergency situations. Recent reports have described that ictal MRI findings, including ictal hyperperfusion on ASL and cortical hyperintensity of cytotoxic edema on DWI, can be obtained from epileptically activated cortex...

PURPOSE: Status epilepticus (SE) in patients with cirrhosis is a rare but serious situation. Diagnosis may be difficult in emergency presentation, especially when patients present with hepatic encephalopathy (HE). Misdiagnosis must be avoided since some anti-epileptic drugs aggravate HE. In this retrospective study, we therefore assessed the frequency of SE in patients with cirrhosis, evaluated the accuracy of diagnosis and determined rates of mortality. METHOD: We reviewed data from all patients hospitalized from 2005 to 2013 in the Hepatology ICU for complications of cirrhosis with an initial diagnosis of SE...

c-jun, a major component of AP-1 transcription factor, has a wide variety of functions. In the embryonic brain, c-jun mRNA is abundantly expressed in germinal layers around the ventricles. Although the subventricular zone (SVZ) of the adult brain is a derivative of embryonic germinal layers and contains neural precursor cells (NPCs), the c-jun expression pattern is not clear. To study the function of c-jun in adult neurogenesis, we analyzed c-jun expression in the adult SVZ by immunohistochemistry and compared it with that of the embryonic brain...

COMMENT
Andrew C Schomer, Jaideep Kapur
In the Lancet Neurology article "Prehospital treatment with levetiracetam plus clonazepam or placebo plus clonazepam in status epilepticus (SAMUKeppra): a randomised, double-blind, phase 3 trial" the authors conducted a prehospital, randomized controlled study to determine which treatment is more effective for status epilepticus (SE): benzodiazepine alone, or in combination with levetiracetam (LEV). Although the study had negative results, several aspects of the trial design likely masked any added effect that LEV may have had in controlling SE, including: higher doses of benzodiazepines, lower thresholds for determining cessation of SE, and a smaller sample size...

Protease-activated receptor 1 (PAR1) is an important contributor to the pathogenesis of a variety of brain disorders associated with a risk of epilepsy development. Using the lithium-pilocarpine model of temporal lobe epilepsy (TLE), we recently showed that inhibition of this receptor during the first ten days after pilocarpine-induced status epilepticus (SE) results in substantial anti-epileptogenic and neuroprotective effects. As PAR1 is expressed in the central nervous system regions of importance for processing emotional reactions, including amygdala and hippocampus, and TLE is frequently associated with a chronic alteration of the functions of these regions, we tested the hypothesis that PAR1 inhibition could modulate emotionally driven behavioral responses of rats experiencing SE...

OBJECTIVE: pre-morbid patient conditions and hospitalization complications possibly play a role in status epilepticus short-term outcome, although evidence is incomplete and non-conclusive. The study's aim was to define whether comorbidities and in-hospital complications arising after status epilepticus affect its prognosis. METHODS: A retrospective single center study was carried out. All selected patients were adults presenting an EEG-proven status epilepticus episode between 2003 and 2014...

BACKGROUND: We wanted to identify in children with epilepsy the factors associated with seizure control and recurrence after a 2-year remission. METHODS: We did a 5-year follow-up of epileptic children whose antiepileptic medication had been stopped. Bivariate and multivariate analyses were used to compare features of electroencephalograms (EEGs) and clinical findings. In this study, 43 patients with and 64 without a seizure recurrence (SR) were enrolled. RESULTS: Clinical features strongly associated with SR in the univariate analysis included a symptomatic etiology for seizures, a history of status epilepticus, treatment duration before stopping antiepileptic drugs, and abnormal EEG findings at the time of stopping antiepileptic drugs...

Several members of the Bcl-2 gene family are dysregulated in human temporal lobe epilepsy and animal studies show that genetic deletion of some of these proteins influence electrographic seizure responses to chemoconvulsants and associated brain damage. The BH3-only proteins form a subgroup comprising direct activators of Bax-Bak that are potently proapoptotic and a number of weaker proapoptotic BH3-only proteins that act as sensitizers by neutralization of antiapoptotic Bcl-2 family members. Noxa was originally characterized as a weaker proapoptotic, 'sensitizer' BH3-only protein, although recent evidence suggests it too may be potently proapoptotic...

A woman underwent ascending aortic aneurysm repair, aortic root and valve replacement, and coronary artery bypass grafting. Her postoperative course was complicated by stroke and status epilepticus. With supportive care and antiepileptics, her neurologic status improved. Intravenous heparin and aspirin were initiated. On postoperative day 13, she developed a large retroperitoneal hematoma with femoral neuropathy. Because her hematoma was not amenable to percutaneous drainage or surgical evacuation, and considering her comorbidities, a conservative approach was elected...
