We report the case of a 67-year-old woman with non-convulsive status epilepticus (NCSE) due to hyponatremia. She had a history of psychogenic polydipsia but not epilepsy. She was admitted to our hospital with dysbulia. On admission, she was confused and disoriented (Glasgow Coma Scale: 6, E1V1M4). Magnetic resonance imaging of the brain showed no abnormalities. Laboratory test showed hyponatremia (Na<sup>+</sup> level: 115 mEq/L). The electroencephalography (EEG) showed a generalized slow wave of 5 Hz during recording...

The differential diagnosis of non-convulsive status epilepticus (NCSE) is often complex due to a wide clinical variability of its presentation, including psychiatric manifestations. We report a 68 years old male with a history of depression treated with venlafaxine, mirtazapine, quetiapine and risperidone, presenting in the emergency room with confusion and generalized rigidity. A brain CT scan did not show lesions. A neuroleptic syndrome was initially suspected. At the third day the obtundation worsened and an electroencephalogram (EEG) was performed, which showed epileptiform abnormalities...

OBJECTIVE: Epilepsy is a neuronal disorder for which the electrical discharge in the brain is synchronized, abnormal and excessive. To detect the epileptic seizures and to analyse brain activities during different mental states, various methods in non-linear dynamics have been proposed. This study is an attempt to quantify the complexity of control and epileptic subject with and without seizure as well as to distinguish eye-open (EO) and eye-closed (EC) conditions using threshold-based symbolic entropy...

Objective. We are reporting two cases: a patient with steroid responsive encephalopathy associated with autoimmune thyroiditis (SREAT) and another patient with secondary progressive multiple sclerosis (SPMS), both presenting with altered mental status (AMS) and later diagnosed with nonconvulsive atypical absence status epilepticus (AS), with atypical EEG changes. Methods. A report of two cases. Results. A patient with history of SREAT and the other with SPMS had multiple admissions due to AMS. For both, EEG revealed the presence of a high voltage generalized sharply contoured theta activity...

REVIEW
M O Kinney, J J Craig, P W Kaplan
Non-convulsive status epilepticus (NCSE) is an electroclinical state associated with an altered level of consciousness but lacking convulsive motor activity. It can present in a multitude of ways, but classification based on the clinical presentation and electroencephalographic appearances assists in determining prognosis and planning treatment. The aggressiveness of treatment should be based on the likely prognosis and the underlying cause of the NCSE.

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: 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...

INTRODUCTION: The medical and healthcare economic burden caused by chronic lumbar back pain (CLBP) requires the use of interdisciplinary treatment approaches. The present study aimed to evaluate whether the effectiveness of inpatient multimodal pain therapy (MPT, operations and procedures (OPS) coding 8-918.02), can be increased by implementing additional neuromuscular core stability exercises (NCSE). MATERIAL AND METHODS: As part of a prospective controlled study, subjects with CLBP (n = 48, 17 males, 58...

The rational design of magnetic and fluorescent bifunctional materials is attracting increasing interest. In this study, two mononuclear Fe(ii) complexes, namely [Fe(L)2(NCS)2] (1) and [Fe(L)2(NCSe)2] (2) are synthesised by combining a spin-crossover unit and a fluorescent ligand (naphth-1-yl)-N-(3,5-di(pyridin-2-yl)-4H-1,2,4-triazol-4-yl)methanimine (L) to achieve bifunctionality. Single-crystal X-ray studies and magnetic measurements confirm the presence of spin crossover behaviours; these measurements agree with the results of the temperature depended Raman spectra and infrared spectra...

PURPOSE: Status epilepticus (SE) is one of the most common neurological emergencies with a high incidence in the elderly. Major determinants of prognosis are patients' age, duration of SE and underlying etiology. We aimed identifying differences in clinical presentation of SE, etiologies and outcome between patients (pts.) sixty years or older (≥60) and younger than sixty (<60) years (yrs). METHODS: We retrospectively analyzed 120 patients (48 women) with SE admitted to the Neurological Intensive Care Unit (NICU), Department of Neurology, Paracelsus Medical University Salzburg, Austria between 1/2011 and 01/2013...

Herein, we review the current state of nonconvulsive status epilepticus (NCSE). NCSE has recently been recognized as one of the causes of unexplained impaired consciousness in the neurosurgical or neurocritical setting. The causes of NCSE include not only central nervous system disorders such as craniotomy, stroke, traumatic brain injury, and central nervous system inflammation, but also severe critical conditions such as sepsis and uremia, among others. NCSE shows no overt clinical manifestations; therefore, prompt and correct diagnosis is difficult...

BACKGROUND: Several EEG criteria have been proposed for diagnosis of non-convulsive status epilepticus (NCSE), but none have been clinically validated. We aimed to assess the diagnostic accuracy of the EEG criteria proposed by a panel of experts at the fourth London-Innsbruck Colloquium on Status Epilepticus in Salzburg, 2013 (henceforth called the Salzburg criteria). METHODS: We did a retrospective, diagnostic accuracy study using EEG recordings from patients admitted for neurological symptoms or signs to three centres in two countries (Danish Epilepsy Centre, Dianalund, Denmark; Aarhus University Hospital, Aarhus, Denmark; and Paracelsus Medical University, Salzburg, Austria)...

AIM: Status epilepticus (SE) can lead to sequelae or even death. Identifying characteristics associated with poor outcome is crucial in guiding patient treatment. Based on our retrospective patient cohorts, potential prognostic factors were analysed. METHODS: Patients consecutively treated for refractory convulsive status epilepticus (CSE) between 2001 and 2010 and non-convulsive status epilepticus (NCSE) between 2004 and 2009 were studied. Outcome was compared to prognostic variables...

OBJECTIVE: The aim of this study was to investigate variant patterns of cortical venous oxygenation during status epilepticus (SE) using susceptibility-weighted imaging (SWI). METHODS: We analyzed magnetic resonance imaging (MRI) scans of 26 patients with clinically witnessed prolonged seizures and/or EEG-confirmed SE. All MRI exams encompassed SWI, dynamic susceptibility contrast perfusion MRI (MRI-DSC) and diffusion-weighted imaging (DWI). We aimed to identify distinct patterns of SWI signal alterations that revealed regional or global increases of cerebral blood flow (CBF) and DWI restrictions...

Cephalosporins, particularly cefepime, exert neurotoxic side effects that can lead to status epilepticus. These neurotoxic side effects include myoclonus, dystonic movements, tremor, asterixis, seizure, status epilepticus, encephalopathy, and sometimes coma. Status epilepticus, particularly nonconvulsive status epilepticus (NCSE), is a well-known but unusual complication in patients with altered renal function who were receiving treatment with intravenous cephalosporins, especially cefepime. We reviewed the clinical and electroencephalographic (EEG) characteristics of 7 patients with renal failure who developed consciousness alterations with changes in EEG activity while being treated with cephalosporins...

Reactions of Fe(II) precursors with the tetradentate ligand S,S'-bis(2-pyridylmethyl)-1,2-thioethane (bpte) and monodentate NCE(-) coligands afforded mononuclear complexes [Fe(bpte)(NCE)2] (1, E = S; 2, E = Se; 3, E = BH3) that exhibit temperature-induced spin crossover (SCO). As the ligand field strength increases from NCS(-) to NCSe(-) to NCBH3(-), the SCO shifts to higher temperatures. Complex 1 exhibits only a partial (15%) conversion from the high-spin (HS) to the low-spin (LS) state, with an onset around 100 K...
