BACKGROUND: The ICCS defines OAB by the subjective symptom of urgency; detrusor overactivity (DO) is only implied. While no other symptom is required, OAB can also be associated with urinary frequency, decreased functional bladder capacity, and incontinence. OBJECTIVE: We sought to determine how often these associated findings occur in OAB and what if any uroflow/EMG-defined conditions are found to be associated with it. METHODS: The charts of 548 children (231M, 318F; mean age 9...

Although rodent models of traumatic brain injury (TBI) reliably produce cognitive and motor disturbances, behavioral characterization resulting from left and right hemisphere injuries remains unexplored. Here we examined the functional consequences of targeting the left versus right parietal cortex in lateral fluid percussion injury, on Morris water maze (MWM) spatial memory tasks (fixed platform and reversal) and neurological motor deficits (neurological severity score and rotarod). In the MWM fixed platform task, right lateral injury produced a small delay in acquisition rate compared to left...

Hemiplegic migraine (HM) is a rare migraine with aura; it can be familiar or sporadic. A 46-years-old man presented left migraine followed by right hemiparesis with bilateral plantar flexion of cutaneous plantar reflex (CPR). Brain CT and CT-angiography were normal. The next day patient got worse. The EEG showed left fronto-temporal cuspidate delta waves and brain MRI showed a minimal hyperintensity at T2-sequences in the left frontal cortex with a minor representation of the cortical veins at susceptibility weighted imaging sequences...

OBJECTIVE: Despite the awareness and familiarity of almost every medical professional with the cauda equine compression syndrome (CES), risk factors for a poor prognosis of the disease remain elusive. Even the relationship between subsequent outcome and the time elapsed from the time of appearance of symptoms to surgery taking place remain obscure. The aim of our study, therefore, was to analyze a relatively large population of our own patients studied consecutively, to identify outcome predictors for CES and to propose a clinical score for CES symptoms (Berlin CES score)...

As head injuries and their sequelae have become an increasingly salient matter of public health, experts in the field have made great progress elucidating the biological processes occurring within the brain at the moment of injury and throughout the recovery thereafter. Given the extraordinary rate at which our collective knowledge of neurotrauma has grown, new insights may be revealed by examining the existing literature across disciplines with a new perspective. This article will aim to expand the scope of this rapidly evolving field of research beyond the confines of the central nervous system (CNS)...

Nanoparticles are of long-standing interest for the treatment of neurological diseases such as glioblastoma. Most past work focused on methods to introduce nanoparticles into the brain, suggesting that reaching the brain interstitium will be sufficient to ensure therapeutic efficacy. However, optimized nanoparticle design for drug delivery to the central nervous system is limited by our understanding of their cellular deposition in the brain. Here, we investigated the cellular fate of poly(lactic acid) nanoparticles presenting different surface chemistries, after administration by convection-enhanced delivery...

Improvement of visual field defects after surgical treatment for occipital lobe epilepsy is rare. Here, the authors report on a 24-year-old man with a 15-year history of refractory epilepsy that developed after he had undergone an occipital craniotomy to remove a cerebellar astrocytoma at the age of 4. His seizures started with an elementary visual aura, followed by secondary generalized tonic-clonic convulsion. Perimetry revealed left-sided incomplete hemianopia, and MRI showed an old contusion in the right occipital lobe...

Intramedullary spinal cord tumors (IMSCTs) represent a rare entity, accounting for 4%-10% of all central nervous system tumors. Microsurgical resection of IMSCTs is currently considered the primary treatment modality. Intraoperative neurophysiological monitoring (IONM) has been shown to aid in maximizing tumor resection and minimizing neurological morbidity, consequently improving patient outcome. The gold standard for IONM to date is multimodality monitoring, consisting of both somatosensory evoked potentials, as well as muscle-based transcranial electric motor evoked potentials (tcMEPs)...

Epigenome editing aims for an introduction or removal of chromatin marks at a defined genomic region using artificial EpiEffectors resulting in a modulation of the activity of the targeted functional DNA elements. Rationally designed EpiEffectors consist of a targeting DNA-binding module (such as a zinc finger protein, TAL effector, or CRISPR/Cas complex) and usually, but not exclusively, a catalytic domain of a chromatin-modifying enzyme. Epigenome editing opens a completely new strategy for basic research of the central nervous system and causal treatment of psychiatric and neurological diseases, because rewriting of epigenetic information can lead to the direct and durable control of the expression of disease-associated genes...

Myasthenia gravis (MG) is a neurological autoimmune disease characterized by fluctuating weakness of certain voluntary muscles. Current treatments for MG are largely directed at suppressing the whole immune system by using immunosuppressants or glucocorticoids and often cause several side effects. The ideal therapeutic methods for MG should suppress aberrant immunoactivation specifically, while retaining normal function of the immune system. In this study, we first produced exosomes from microRNA-146a overexpressing dendritic cells (DCs)...

REVIEW
John M Dean, Irfan J Lodhi
Ether lipids, such as plasmalogens, are peroxisome-derived glycerophospholipids in which the hydrocarbon chain at the sn-1 position of the glycerol backbone is attached by an ether bond, as opposed to an ester bond in the more common diacyl phospholipids. This seemingly simple biochemical change has profound structural and functional implications. Notably, the tendency of ether lipids to form non-lamellar inverted hexagonal structures in model membranes suggests that they have a role in facilitating membrane fusion processes...

BACKGROUND: Resolution of inflammation is an emerging new strategy to reduce damage following ischemic stroke. Lipoxin A4 (LXA 4) is an anti-inflammatory, pro-resolution lipid mediator that reduces neuroinflammation in stroke. Since LXA 4 is rapidly inactivated, potent analogs have been synthesized, including BML-111. We hypothesized that post-ischemic, intravenous treatment with BML-111 for 1 week would provide neuroprotection and reduce neurobehavioral deficits at 4 weeks after ischemic stroke in rats...
