#1
Olivier Walusinski
Yawning, laughing, and crying are normal physiological behaviors of humans in good health. As with all physiological behaviors, their deregulation can reveal disorders. Pathological yawning occurs in salvos of 10-20 successive yawns, and the number of yawns per day can exceed one hundred. After listing the functional etiologies, we will give the clinical keys for differentiating the most serious causes: iatrogenic, tumors, strokes, amyotrophic lateral sclerosis, and intracranial hypertension. Sudden, uncontrollable episodes of emotional display involving pathological laughing and crying (PLC) may be encountered in various neurological diseases: amyotrophic lateral sclerosis, multiple system atrophy (cerebellar), cerebrovascular disease, traumatic brain injuries, mass lesions in the cerebellopontine junction, and epilepsy...

BACKGROUND: Multimodal computed tomography imaging (MCTI) is increasingly used for rapid assessment of acute stroke. We investigated characteristics and final diagnoses of patients treated with recombinant tissue plasminogen activator (rt-PA) while admission imaging was unremarkable. METHODS: From our prospectively collected stroke database (2013-2016), we identified consecutive patients treated with rt-PA on the basis of an unremarkable brain MCTI and assessed with a 24-hour follow-up brain magnetic resonance imaging (MRI)...

Maternal deaths of indirect causes result of a preexisting disease or an affection appeared during the pregnancy without any relationship with obstetrical causes, but worsened by the physiological effects of pregnancy. Among the 23 deaths of indirect cause related to a preexisiting pathology, 22 (96 %) have been analyzed by the expert comity. A known or preexisting chronic disease was documented in 16 patients (sick-cell disorder, n=3, treated epilepsy, n=3, intracerebral carvenomas, n=1, multifocal glial tumor, n=1, breast cancer, n=1, systemic lupus, n=1, diabetes mellitus, n=3, antiphospholipid syndrome, n=1)...

BACKGROUND: Late-onset poststroke seizure is highly associated with epilepsy but the incidence of it is variable due to different definition and follow-up time. We conducted a meta-analysis to determine the incidence of poststroke seizure and analyze the discrepancies among published studies. METHODS: We searched the literature for relevant articles published in English between January 1, 1990, and December 31, 2014, by using the following search terms: "seizures after stroke," "poststroke seizures," "epilepsy after stroke," "poststroke epilepsy," "incidence," and "follow-up...

OBJECTIVE: To evaluate the incidence rate and relative risk of a seizure disorder after eclampsia. METHODS: We evaluated 1,565,733 births in a retrospective data linkage cohort study in Ontario, Canada, from April 1, 2002, to March 31, 2014. We included females aged 15-50 years and excluded patients with epilepsy, conditions predisposing to seizure, and those who died within 30 days of the delivery discharge date. The exposure was defined as a hypertensive disorder of pregnancy, namely 1) eclampsia, 2) preeclampsia, or 3) gestational hypertension...

Epilepsy is a neurologic condition which often occurs with other neurologic and psychiatric disorders. The relation between epilepsy and these conditions is complex. Some population-based studies have identified a bidirectional relation, whereby not only patients with epilepsy are at increased risk of suffering from some of these neurologic and psychiatric disorders (migraine, stroke, dementia, autism, depression, anxiety disorders, Attention deficit hyperactivity disorder (ADHD), and psychosis), but also patients with these conditions are at increased risk of suffering from epilepsy...

The major objective of preclinical translational epilepsy research is to advance laboratory findings toward clinical application by testing potential treatments in animal models of seizures and epilepsy. Recently there has been a focus on the failure of preclinical discoveries to translate reliably, or even to be reproduced in different laboratories. One potential cause is a lack of standardization in preclinical data collection. The resulting difficulties in comparing data across studies have led to high cost and missed opportunity, which in turn impede clinical trials and advances in medical care...

Focused ultrasound (FUS) produces a region of high intensity at the focal zone of the beam but with minimal effects at adjacent areas, allowing the sonication of deep targets throughout the body. Despite early obstacles to transmitting ultrasound energy through the skull, recent advances in ultrasound technology, software, and real-time monitoring have resulted in a renewed interest in the clinical applications of transcranial FUS. Following extensive pre- clinical studies, ultrasound-induced thermal ablation has been approved by several countries for the treatment of essential tremor, Parkinson's disease, obsessive-compulsive disorder, depression, and neuropathic pain...

 In most cases, the etiology of epilepsy is unknown, although some individuals may develop epilepsy as a result of certain brain injuries, following a stroke, a brain tumor or because of drugs and alcohol. Even some rare genetic mutations may be related to the onset of the condition. Seizures are the result of excessive and abnormal activity of neurons in the cerebral cortex. In this case report we show a clinical case of refractory epilepsy due to pain related to uncontrolled dysmenorrhea. The patient, 43 yrs old, had a history of epilepsy of 20 years and ovarian cancer...

Continuous brain imaging techniques can be beneficial for the monitoring of neurological pathologies (such as epilepsy or stroke) and neuroimaging protocols involving movement. Among existing ones, functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG) have the advantage of being noninvasive, nonobstructive, inexpensive, yield portable solutions, and offer complementary monitoring of electrical and local hemodynamic activities. This article presents a novel system with 128 fNIRS channels and 32 EEG channels with the potential to cover a larger fraction of the adult superficial cortex than earlier works, is integrated with 32 EEG channels, is light and battery-powered to improve portability, and can transmit data wirelessly to an interface for real-time display of electrical and hemodynamic activities...

INTRODUCTION: The literature review revealed that nowadays only about 15 cases of bilateral shoulder dislocation associated with the fracture of the upper end of the humerus have been published. The triad of lesional mechanism designated by the triple syndrome E composed of epilepsy, electrocution, and external trauma was the circumstances noted in which these fractures dislocations occur with migration of the two humeral heads either forward or backward. CASE REPORT: An architect of 36-year-old, right-handed, was admitted in emergency department for loss of knowledge of progressive installation...

REVIEW

Blood coagulation factors and other proteins, with modulatory effects or modulated by the coagulation cascade have been reported to affect the pathophysiology of the central nervous system (CNS). The protease-activated receptors (PARs) pathway can be considered the central hub of this regulatory network, mainly through thrombin or activated protein C (aPC). These proteins, in fact, showed peculiar properties, being able to interfere with synaptic homeostasis other than coagulation itself. These specific functions modulate neuronal networks, acting both on resident (neurons, astrocytes, and microglia) as well as circulating immune system cells and the extracellular matrix...

REVIEW
Geoffrey Burnstock
Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990's when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine) receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling...

BACKGROUND: An increasing amount of evidence suggests an association between epilepsy and multiple somatic and psychiatric conditions, which is more significant than in the general population. Furthermore, a bidirectional association has been established between epilepsy and several conditions, notably depression and suicide, cerebrovascular disease, stroke, dementia and migraine, which is best explained by the presence of common underlying mechanisms and risk factors. Gaining knowledge about these common mechanisms can provide insight into new therapeutic targets, screening and preventive measures...

NMDA-type glutamate receptors are ligand-gated ion channels that mediate a major component of excitatory neurotransmission in the central nervous system (CNS). They are widely distributed at all stages of development and are critically involved in normal brain functions, including neuronal development and synaptic plasticity. NMDA receptors are also implicated in the pathophysiology of numerous neurological and psychiatric disorders, such as ischemic stroke, traumatic brain injury, Alzheimer's disease, epilepsy, mood disorders, and schizophrenia...
