Ketogenic diet (KD) which combined carbohydrate restriction and the addition of ketone bodies has emerged as an alternative metabolic intervention used as an anticonvulsant therapy or to treat different types of neurological or mitochondrial disorders including MELAS syndrome. MELAS syndrome is a severe mitochondrial disease mainly due to the m.3243A > G mitochondrial DNA mutation. The broad success of KD is due to multiple beneficial mechanisms with distinct effects of very low carbohydrates and ketones...

INTRODUCTION: Drowning leads to 372,000 deaths annually worldwide and to severe morbidity secondary to asphyxiation or aspiration. Previous studies described submersion injuries mainly in the pediatric population. This study describes characteristics of patients presenting with submersion injuries to United States emergency departments (EDs) and identifies predictors of poor outcomes (death or long term neurologic deficits) after drowning. METHODS: This retrospective cross-sectional study included ED visits for submersion injuries from the United States 2013 Nationwide Emergency Department Sample (NEDS) dataset using discharge data (CCS diagnosis codes)...

In 2030, one in five Americans will be older than 65 years, and with that an increase in the number of individuals who experience loss in cognitive capacity is to be expected. At the same time, nutrition within the first 1000 days postconception has been suggested to strongly influence cognitive outcomes across the life-span in humans. Eggs are a primary source of both choline and the xanthophyll carotenoid lutein in the western diet, and both have been suggested to influence cognitive function in humans. This comprehensive review critically examines the effects of eggs, choline, and lutein on cognition across the life-span...

Multiple Sclerosis (MuS) is a complex multifactorial neuropathology, resulting in heterogeneous clinical presentation. A very active MuS research field concerns the discovery of biomarkers helpful to make an early and definite diagnosis. The sphingomyelin pathway has emerged as a molecular mechanism involved in MuS, since high levels of ceramides in cerebrospinal fluid (CSF) were related to axonal damage and neuronal dysfunction. Ceramides are the hydrolysis products of sphingomyelins through a reaction catalyzed by a family of enzymes named sphingomyelinases, which were recently related to myelin repair in MuS...

The study aims to describe the organizational framework of International Medical Evacuation (IME), the profile of persons evacuated, and the associated cost of IME in Guinea. This was a descriptive study of IME policy in Guinea. We described the politico-structural organization of IME and the profile of patient accessing IME through the Ministry of Health (MOH: 2001-2015) and through the National Social Security Fund (NSSF: 2011-2015). From 1958 to 1992 since the health system was restricted, the country negotiated the free medical treatment with Socialist countries...

OBJECTIVE: To describe acute headache diagnoses in women presenting emergently in the postpartum period and to determine which factors may be associated with secondary vs primary headache. BACKGROUND: Hormonal, vascular, and procedural factors elevate the risk for both secondary and primary headache disorders in the postpartum period. Differentiating between these can be a diagnostic challenge, particularly among the most severe patients referred for urgent neurological consultation...

Multiple sclerosis (MS) is a chronic and debilitating neurological disorder of the central nervous system (CNS), characterized by infiltration of leukocytes into CNS and subsequent demyelination. Emerging evidences have revealed the beneficial roles of M2 macrophages in ameliorating experimental autoimmune encephalomyelitis (EAE), a model for MS. Here, we identify that lenalidomide alone could promote macrophages M2 polarization to prevent the progression of EAE, which is associated with subsequent inhibition of proinflammatory Th1 and Th17 cells both in peripheral lymph system and CNS...

Zika virus (ZIKV) is an arbovirus transmitted mainly by mosquitos of Aedes species. The virus has emerged in recent years and spread throughout North and South Americas. The recent outbreak of ZIKV started in Brazil (2015) has resulted in infections surpassing a million mark. Contrary to the previous beliefs that Zika causes mildly symptomatic infections fever, headache, rash, arthralgia, and conjunctivitis, the recent outbreak associated ZIKV to serious neurological complications such as microcephaly, Guillain-Barré syndrome, and eye infections...

The WHO has ranked environmental hazardous exposures in the living and working environment among the top risk factors for chronic disease mortality. Worldwide, about 40 million people die each year from noncommunicable diseases (NCDs) including cancer, diabetes, and chronic cardiovascular, neurological and lung diseases. The exposure to ambient pollution in the living and working environment is exacerbated by individual susceptibilities and lifestyle-driven factors to produce complex and complicated NCD etiologies...

PURPOSE OF REVIEW: Migraine is an extremely incapacitating collection of neurological symptoms that usually includes a severe, throbbing, recurring pain on one side of the head. The World Health Organization ranks migraine as the third most prevalent disease and the seventh commonest primary pain condition in the world. Trigeminovascular-mediated central sensitization has been implicated in the development of migraine symptoms including pain following light touch. This review explores the activation and sensitization of the brain systems that have emerged from recent studies and that contribute to migraine...

OBJECTIVE: In their 1973 BMJ paper 'Cryptogenic Drop Attacks', Stevens and Matthews described 40, mostly middle-aged, female patients with drop attacks of unknown cause. Although clinically common, there has been little on this topic since. We aimed to determine clinical features, comorbidity and outcome of patients with drop attacks. METHODS: We carried out a retrospective review of patients with cryptogenic drop attacks seen consecutively by one clinician (JS) between 2006 and 2016...

PURPOSE OF REVIEW: With advances in medical care, the number of youths surviving with medically complex conditions has been steadily increasing. Inadequate transition planning and execution can lead to gaps in care, unexpected emergency department visits, and an increase in health care costs and patient/caregiver anxiety. Many barriers that prevent adequate transition have been identified, including insufficient time or staff to provide transition services, inadequate reimbursement, resistance from patients and caregivers, and a dearth of accepting adult providers...

PURPOSE OF REVIEW: This article provides an overview of genetic metabolic disorders that can be identified by metabolic tests readily available to neurologists, such as tests for ammonia, plasma amino acids, and urine organic acids. The limitations of these tests are also discussed, as they only screen for a subset of the many inborn errors of metabolism that exist. RECENT FINDINGS: Advances in next-generation sequencing and the emerging use of advanced metabolomic screening have made it possible to diagnose treatable inborn errors of metabolism that are not included in current newborn screening programs...

PURPOSE OF REVIEW: Providing an overview on Mycoplasma pneumoniae-related extra-pulmonary diseases (MpEPDs) in children, who represent the preferred target population by those complications, and discussing the main pathogenic mechanisms implicated or potentially involved. RECENT FINDINGS: Recent evidences supported the fact that M. pneumoniae is more than an extra-cellular pathogen colonizing epithelial cells of the respiratory tract. It is able to penetrate the cell membrane of host cells and to invade the respiratory mucosa, leading to pronounced inflammatory responses and also spreading outside the respiratory system, to some extent...

Hyperosmolar hyperglycemic state is a life-threatening emergency manifested by marked elevation of blood glucose and hyperosmolarity with little or no ketosis. Although there are multiple precipitating causes, underlying infections are the most common. Other causes include certain medications, nonadherence to therapy, undiagnosed diabetes mellitus, substance abuse, and coexisting disease. In children and adolescents, hyperosmolar hyperglycemic state is often present when type 2 diabetes is diagnosed. Physical findings include profound dehydration and neurologic symptoms ranging from lethargy to coma...
