Trigeminal trophic syndrome (TTS) is a condition whereby persistent facial ulceration presents consequent to central or peripheral insult to the trigeminal nerve. Lesions are created by repetitive self-inflicted manipulation and trauma of dysaesthetic skin within the trigeminal dermatome. We discuss four cases with aetiologies varied from presumed microvascular compromise to resection of cerebral meningioma, cerebrovascular accident, and herpes zoster ophthalmicus. We discuss the management of the under-recognised associated periocular skin ulcerations that result from physical manipulation of dysesthic skin and prove to be persistent and challenging to treat...

Glutamate is the major excitatory neurotransmitter in the brain, but excessive synaptic glutamate must be removed to prevent excitotoxic injury and death. Two astrocytic glutamate transporters, excitatory amino acid transporter (EAAT) 1 and 2, play a major role in eliminating excess glutamate from the synapse. Dysregulation of EAAT1 contributes to the pathogenesis of multiple neurological disorders, such as Alzheimer's disease (AD), ataxia, traumatic brain injuries, and glaucoma. In the present study, we investigated the effect of arundic acid on EAAT1 to determine its efficacy in enhancing the expression and function of EAAT1, and its possible mechanisms of action...

Therapeutic hypothermia (TH) is a neuroprotective treatment post-cardiac arrest but is grossly underutilized. After TH induction, traditional biomarkers and parameters can no long predict clinical outcome due to a lack of understanding of hypothermic response. Innovative approaches to better understand the clinical effect of TH will help to prognosticate outcome and expand beneficial population. Protein glycosylation is an important extracellular post-translational modification, regulating various extracellular signaling pathways...

BACKGROUND: Resection of tumors close to the corticospinal tract (CST) carries a high risk of damage to the CST. For cystic tumors, aspirating the cyst before resection may reduce the risk of damage to vital structures. This study evaluated the effectiveness of cyst aspiration, by comparing the results before and after aspiration of diffusion tensor image (DTI) tractography. METHODS: This study enrolled 23 patients with large cystic brain tumors (>20 cm(3)) between 2012 and 2016...

Erucic acid (cis-docosa-13-enoic acid, C22:1∆13) and nervonic acid (cis-tetracosa-15-enoic acid, C24:1 ∆15) are important renewable feedstocks in plastic, cosmetic, nylon, and lubricant industries. Furthermore, nervonic acid is also applied to the treatment of some neurological diseases. However, the production of these two very long-chain fatty acids (VLCFA) is very limited as both are not present in the main vegetable oils (e.g., soybean, rapeseed, sunflower, and palm). Ectopic integration and heterologous expression of fatty acid elongases (3-ketoacyl-CoA synthases, KCS) from different plants in Rhodosporidium toruloides resulted in the de novo synthesis of erucic acid and nervonic acid in this oleaginous yeast...

STUDY DESIGN: Narrative literature review. OBJECTIVE: The numbers of low-energy cervical fractures seen in patients suffering from ankylosing spondylitis (also known as Bechterew disease) or diffuse idiopathic skeletal hyperostosis (also known as Forestier disease) have greatly increased over recent decades. These fractures tend to be particularly overlooked, leading to delayed diagnosis and secondary neurological deterioration. The aim of the present evaluation was to summarize current knowledge on cervical fractures in patients with ankylosing spinal disorders (ASDs)...

Neuro-Behçet's disease (NBD) is a rare clinical entity that frequently presents neuro-psychiatric symptoms, and mesodiencephalic and pontobulbar lesions. There is only one published report about osteonecrosis in NBD. We report a patient whose first presentation was neurological NBD with presenting bilateral femoral heads osteonecrosis. A 36-year-old male was hospitalized with gait disorder, diplopia and speech disorder. The past medical history of the patient was unremarkable. The MR image showed mesencephalic lesion with oedemaas a hyperintense area...

Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme of folate pathway and required for DNA synthesis and methylation. MTHFE C677T polymorphisms is reported as risk factors for various diseases and disorders like birth defects, metabolic, neurological, psychiatric disorders, and cancers. Several studies have investigated association between the MTHFR C677T polymorphism and male infertility. To assess the risk associated with MTHFR C677T polymorphism in Asian population, a meta-analysis was performed...

Catecholamine neurotransmitters, generally including dopamine (DA), epinephrine (EP) and norepinephrine (NE) are known as substantial indicators of various neurological diseases. Simultaneous detection of these compounds and their metabolites is highly recommended in early clinical diagnosis. To this aim, in the present contribution, a high performance colorimetric sensor array has been proposed for the detection and discrimination of catecholamines based on their reducing ability to deposit silver on the surface of gold nanorods (AuNRs)...

Epigenetic regulation is based on a network of complexes that modulate the chromatin character and structure of the genome to impact gene expression, cell fate, and development. Thus, epigenetic modulators represent novel therapeutic targets used to treat a range of diseases, including malignancies. Infectious pathogens such as herpesviruses are also regulated by cellular epigenetic machinery, and epigenetic therapeutics represent a novel approach used to control infection, persistence, and the resulting recurrent disease...

Unlike the 1p36 microdeletion syndrome, which has been extensively described, 1p36 microduplications have rarely been reported. We describe a three years old boy presenting with a severe global developmental delay and a few dysmorphic features. Cytogenetic analyses revealed a maternally inherited 3.35 Mb microduplication of chromosomal band 1p36.3. The maternal grand-father is also carrier of the same chromosomal rearrangement. Interestingly, the duplicated 1p36.3 segment was found to be localized at the telomeric end of the long arms of a chromosome 9, probably deriving from a 1p36...

The 2015 Brazilian Zika virus outbreak sparked a rapid response to control the spread of the virus. What was first understood to be a mild self-resolving infection is now linked to significant neurological defects in both neonates, and adults. The WHO declared the 2016 Zika epidemic a public health emergency and issued an unprecedented recommendation to women in affected regions to delay pregnancy until the risks surrounding Zika virus could be understood, or the epidemic contained. Since that time, considerable effort has been dedicated to understanding Zika transmission and pathogenesis to aid the development of drugs and vaccines...

BACKGROUND: Posterior decompression surgeries of cervical spine such as laminoplasty and laminoforaminotomy are well established and increasing in aging population. The anatomical knowledge of cervical ligamentum flavum (LF) is critical to perform posterior spinal surgeries, however, few studies have evaluated it, especially the relation of LF and neural foramen. METHODS: The whole spine was removed en bloc from 15 formalin-embalmed human cadavers and then divided into two segments along the pedicle bases...

REVIEW
Mohamed El-Dib, Janet S Soul
Neonatal seizures constitute the most frequent presenting neurologic sign encountered in the neonatal intensive care unit. Despite limited efficacy and safety data, phenobarbital continues to be used near-universally as the first-line anti-seizure drug (ASD) in neonates. The choice of second-line ASDs varies by provider and institution, and is still not supported by sufficient scientific evidence. In this review, we discuss the available evidence supporting the efficacy, mechanism of action, potential adverse effects, key pharmacokinetic characteristics such as interaction with therapeutic hypothermia, logistical issues, and rationale for use of neonatal ASDs...

BACKGROUND: Pathogenic heterozygous variants in the ATP1A2 gene have most commonly been associated with familial hemiplegic migraine. However, a wide spectrum of phenotypes that include alternating hemiplegia of childhood and epilepsy have been described. PATIENT DESCRIPTION: We describe a boy who presented at age three months with a complex phenotype that included epilepsy, nonepileptic paroxysmal events, and recurrent hemiplegia. Magnetic resonance imaging demonstrated unilateral cortical edema during a severe episode of hemiplegia that was followed by a persistent mild hemiparesis...

BACKGROUND: After one episode of exertional heat stroke (EHS), risk factors must be identified to determine the potential for subsequent episodes. One of these risk factors, core body temperature (Tco) kinetics during strenuous exercise, may be a surrogate marker suggestive of impaired thermoregulation. This study aimed to determine the kinetics of increases in Tco among military subjects who had a history of EHS. METHODS: Forty subjects (38 males, mean age 28.4 ± 4...
