Traumatic brain injury (TBI) continues to be the leading cause of death and acquired disability in young children and adolescents, due to blunt or penetrating trauma, the latter being less common but more lethal. Penetrating brain injury (PBI) has not been studied extensively, mainly reported as case reports or case series, due to the assumption that both types of brain injury have common pathophysiology and consequently common management. However, recommendations and guidelines for the management of PBI differ from those of blunt TBI in regards to neuroimaging, intracranial pressure (ICP) monitoring, and surgical management including those pertaining to vascular injury...

The World Health Organization (WHO) classification of central nervous system (CNS) tumors was revised in 2016 with a basis on the integrated diagnosis of molecular genetics. We herein provide the guidelines for using molecular genetic tests in routine pathological practice for an accurate diagnosis and appropriate management. While astrocytomas and IDH-mutant (secondary) glioblastomas are characterized by the mutational status of IDH, TP53 , and ATRX , oligodendrogliomas have a 1p/19q codeletion and mutations in IDH, CIC , FUBP1 , and the promoter region of telomerase reverse transcriptase ( TERTp )...

BACKGROUND: Chronic neck pain affects 50% - 85% of people who have experienced an acute episode. This transition and the persistence of chronic complaints are believed to be mediated by brain alterations among different central mechanisms. OBJECTIVES: This study aimed to systematically review and critically appraise the current existing evidence regarding structural and functional brain alterations in patients with whiplash associated disorders (WAD) and idiopathic neck pain (INP)...

Return to drive after brain damage is a crucial question either for patients than health professionals. The Société française de medicine physique et de réadaptation (SOFMER) and Comète France association developed recommandations for patient's identification, evaluation and accompaniment as part of their project to resume to drive. The place of rehabilitation process and patient's focus has been also discussed. AIMS: Using a literature review, the aim was to define clinical pathways to determine people who need a fitness to drive evaluation after a non-evolutive brain damage as well as the assessment process...

L Turco, D L Cornell, B Phillips
BACKGROUND: Head injuries that cross midline structures of the brain are 'bihemispheric.' Other terms have been used to describe such injuries, but 'bihemispheric' is the most accurate and should be standard nomenclature. Bihemispheric head injuries are associated with higher mortality and morbidity than other penetrating traumatic brain injuries (TBI). Currently, there is a tendency to manage severe gunshot wounds (GSWs) to the head non-operatively, despite reports of improved outcome in military patients treated aggressively...

[(123)I]IBZM is used widely for in vivo imaging of D2 receptors in human brain and shows relatively fast kinetics and a greater susceptibility to synaptic dopamine release than other single-photon emission computed tomography (SPECT) radioligands. A reliable and reversed-phase HPLC method using UV/VIS and radiometric detectors has been developed for qualitative analysis of BZM and IBZM and radiochemical purity in [(123)I]IBZM preparations. The method uses gradient elution on a Zorbax XDB C-18 column with a mobile phase that consists of 10mM 3,3-dimethylglutaric acid (DMGA), pH 7...

OBJECTIVE: To determine if beta-(β)-blockers improve outcomes after acute traumatic brain injury (TBI). BACKGROUND: There have been no new inpatient pharmacologic therapies to improve TBI outcomes in a half-century. Treatment of TBI patients with β-blockers offers a potentially beneficial approach. METHODS: Using MEDLINE, EMBASE, and CENTRAL databases, eligible articles for our systematic review and meta-analysis (PROSPERO CRD42016048547) included adult (age ≥ 16 years) blunt trauma patients admitted with TBI...

Neurodevelopmental reflex testing is commonly used in clinical practice to assess the maturation of the nervous system. Neurodevelopmental reflexes are also referred to as primitive reflexes. They are sensitive and consistent with later outcomes. Abnormal reflexes are described as an absence, persistence, reappearance, or latency of reflexes, which are predictive indices of infants that are at high risk for neurodevelopmental disorders. Animal models of neurodevelopmental disabilities, such as cerebral palsy, often display aberrant developmental reflexes, as would be observed in human infants...

Deep brain stimulation (DBS) is an effective therapy for Parkinson's disease patients experiencing motor fluctuations, medication-resistant tremor, and/or dyskinesia. Currently, the subthalamic nucleus and the globus pallidus internus are the two most widely used targets, with individual advantages and disadvantages influencing patient selection. Potential DBS patients are selected using the few existing guidelines and the available DBS literature, and many centers employ an interdisciplinary team review of the individual's risk-benefit profile...

Stable isotope labeling by amino acids in cell culture (SILAC) is a versatile mass spectrometry-based proteomic approach that can achieve accurate relative protein quantitation on a global scale. In this approach, proteins are labeled while being synthesized by the cell due to the presence of certain amino acids exclusively as heavier mass analogs than their regular (light) counterparts. This differential labeling allows for the identification of heavy and light forms of each peptide corresponding to two or more different experimental groups upon mass spectrometric analysis, the intensities of which reflect their abundance in the sample analyzed...

Accumulation of brain iron is linked to aging and protein-misfolding neurodegenerative diseases. High iron intake may influence important brain health outcomes in later life. The aim of this systematic review was to examine evidence from animal and human studies of the effects of high iron intake or peripheral iron status on adult cognition, brain aging, and neurodegeneration. MEDLINE, Scopus, CAB Abstracts, the Cochrane Central Register of Clinical Trials, and OpenGrey databases were searched. Studies investigating the effect of elevated iron intake at all postnatal life stages in mammalian models and humans on measures of adult brain health were included...

Traumatic brain injury (TBI) is a common injury on the battlefield. Much of what medics do to manage these injuries on the battlefield can be translated to other austere environments, such as wilderness or disaster settings. The recognition and diagnosis of TBI can be difficult even in the hospital, but basic understanding of how to define a TBI and prevent secondary injuries can be accomplished with relatively few resources and little training. This article outlines what a TBI is and how to manage it in the field...

7,8-hydroxy-2'-deoxyguanosine (8-OHdG) is an abundant DNA lesion formed by oxidation of the nucleoside 2'-deoxyguanosine (2-dG) and one of the most studied and accepted oxidative stress biomarkers. 8-OHdG has a strong carcinogenic potential, and prolonged oxidative stress heightens pathological conditions and especially cancer risk. Our aim was to develop, validate and apply a reliable method to assess DNA oxidation in genomic cellular DNA of sensible target organs such as brain. A procedure to isolate and digest the DNA of brain tissue properly for further detection of 8-OHdG and 2-dG by Ultra Performance Liquid Chromatography-tandem Mass Spectrometry (UPLC-MS/MS) was optimized...

Two population-based studies key to advancing knowledge of brain aging are the Honolulu-Asia Aging Study (HAAS) and the Nun Study. Harmonization of their neuropathologic data allows cross comparison, with findings common to both studies likely generalizable, while distinct observations may point to aging brain changes that are dependent on sex, ethnicity, environment, or lifestyle factors. Here, we expanded the neuropathologic evaluation of these 2 studies using revised NIA-Alzheimer's Association guidelines and compared directly the neuropathologic features of resistance and apparent cognitive resilience...

Abnormalities of lateral temporal lobe development are associated with a spectrum of genetic and environmental pathologic processes, but more normative data are needed for a better understanding of gyrification in this brain region. Here, we begin to establish guidelines for the analysis of the lateral temporal lobe in humans in early life. We present quantitative methods for measuring gyrification at autopsy using photographs of the gross brain and simple computer-based quantitative tools in a cohort of 28 brains ranging in age from 27 to 70 postconceptional weeks (end of infancy)...

REVIEW
Giovanni Corona, Alessandra Sforza, Mario Maggi
Recent position statements and guidelines have raised the distinction between a true and false, age-related hypogonadism (HG) or late-onset hypogonadism (LOH). The former is the consequence of congenital or acquired "organic" damage of the brain centers or of the testis. The latter is mainly secondary to age-related comorbidities and does not require testosterone (T) therapy (TTh). In addition, concerns related to cardiovascular (CV) safety have further increased the scepticism related to TTh. In this paper, we reviewed the available evidence supporting the efficacy of TTh in non-organic HG and its long term safety...

OBJECTIVES: Deep brain stimulation (DBS) is a well-established treatment for the management of severe motor fluctuations in advanced Parkinson's disease (PD). Until recently, device regulation, medical, and insurance practices limited DBS to patients with advanced stages of PD. In February 2016 this changed, however, when the US Food and Drug Administration (FDA) granted formal approval for the use of brain stimulator in mid-stage PD patients. In this article, we examine whether DBS in mid-stage PD can be ethically justified beyond the FDA approval...

For a long time, radiation-induced skin injuries were only encountered in patients undergoing radiation therapy. In diagnostic radiology, radiation exposures of patients causing skin injuries were extremely rare. The introduction of fast multislice CT scanners and fluoroscopically guided interventions (FGI) changed the situation. Both methods carry the risk of excessive high doses to the skin of patients resulting in skin injuries. In the early nineties, several reports of epilation and skin injuries following CT brain perfusion studies were published...
