T Witte, X Baraliakos
BACKGROUND: Axial spondyloarthritis (axSpA) is a frequent disorder, which is difficult to diagnose in the early phase. Currently, magnetic resonance imaging (MRI) of the sacroiliac joints and the spine is frequently applied in this phase, when conventional X rays still provide inconclusive results. OBJECTIVE: To explain the typical pathological results and the role of MRI in diagnosing axSpA. RESULTS: The use of MRI of the sacroiliac joints plays a central role in the assessment of the Spondyloarthritis International Association Society (ASAS) classification criteria of axSpA...

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)...

PURPOSE OF THE STUDY Various spine disorders are regularly treated by orthoses, and success of treatment depends on wearing these devices. In this study we examined the compliance, wear comfort, subjective stabilization and side effects associated with spinal orthoses using an individualized questionnaire and the Compact Short Form-12 Health Survey (SF-12). MATERIAL AND METHODS In this prospective pilot study of randomized cross-over design, twelve healthy volunteers with a mean age of 31.2 years wore three different types of orthoses, each for one week: A hyperextension brace (HB), a custom-made semirigid orthosis (SO) and a custom-made rigid orthosis (RO)...

BACKGROUND: Symptomatic chronic low back and leg pain resulting from lumbar spine degenerative disorders is highly prevalent in China, and for some patients, surgery is the final option for improvement. Several techniques for spinal non-fusion have been introduced to reduce the side-effects of fusion methods and hasten postoperative recovery. In this study, the authors have evaluated the cost-effectiveness of Dynesys posterior dynamic stabilization system (DY) compared with lumbar fusion techniques in the treatment of single-level degenerative lumbar spinal conditions...

Chronic stress is a risk factor for a number of physiological disorders including cardiovascular disease, obesity and gastrointestinal disorders, as well as psychiatric and neurodegenerative disorders. There are a number of underlying molecular and cellular mechanisms altered in the course of chronic stress, which may increase the vulnerability of individuals to develop psychiatric disorders such as depression, and neurodegenerative disorders such as Alzheimer's Disease (AD). This is evident in the influence of stress on large-scale brain networks, including the resting state Default Mode Network (DMN), the effects of stress on neuronal circuitry and architecture, and the cellular and molecular adaptations to stress, which may render individuals with stress related psychiatric disorders more vulnerable to neurodegenerative disease later in life...

BACKGROUND: Temporomandibular disorders (TMDs) are prevalent multifactorial pathologies in which the actual role of the cervical region position is controversial. OBJECTIVE: To analyze the relationship between the position of the upper cervical rachis and the symptoms of TMD. METHODS: Sixty women were recruited to this study. All of them completed a questionnaire and were subjected to a temporomadibular exploration to create two different groups: a TMD Group (n= 30) - women who suffered TMD symptoms according to the evaluation; and a control group (n= 30) - women who were free from TMD symptoms...

RATIONALE: Rodents exposed prenatally to valproic acid (VPA) exhibit autism spectrum disorder (ASD)-like behavioral abnormalities. We recently found that prenatal VPA exposure causes hypofunction of the prefrontal dopaminergic system in mice. This suggests that the dopaminergic system may be a potential pharmacological target for treatment of behavioral abnormalities in ASD patients. OBJECTIVES: In the present study, we examined the effects of antipsychotic drugs, which affect the dopaminergic system, on the social interaction deficits, recognition memory impairment, and reduction in dendritic spine density in the VPA mouse model of ASD...

INTRODUCTION: Scoliosis is a complex three-dimensional spine deformity with the frontal plane deflexion (side-shift) of the series of vertebra from the midline and with torque deformity of vertebra, ribs, and the entire trunk towards the apex of curve. Chronic venous diseases present a group of pathological conditions caused by the increased venous pressure. The venous pressure may be increased due to genetics, ligament laxity, general obesity, injuries, and changes in biomechanics of spine and lower extremities, etc...

BACKGROUND: Cervical spondylotic myelopathy (CSM) is a disorder that can cause neurologic deterioration. Studies on paraspinal muscular atrophy (PMA) in the lumbar spine have shown these changes are caused by several perioperative factors. It is possible that PMA in the cervical spine could behave similarly. In this retrospective study, we compared the degree of PMA after laminoplasty versus laminectomy and fusion (LF) using a standard posterior approach to the cervical spine. METHODS: 18 laminoplasty and 43 LF patients were included in this study...

BACKGROUND: There is a growing concern that the use of prescription opioids following surgical interventions, including spine surgery, may predispose patients to chronic opioid use and abuse. We sought to estimate the proportion of patients using opioids up to 1 year after discharge following common spinal surgical procedures and to identify factors associated with sustained opioid use. METHODS: This study utilized 2006 to 2014 data from TRICARE insurance claims obtained from the Military Health System Data Repository...

Turmeric or Curcuma is a natural product that has anti-inflammatory, antioxidant and anti-apoptotic pharmacological properties. It can be used in the control of the aging process that involves oxidative stress, inflammation, and apoptosis. Aging is a physiological process that affects higher cortical and cognitive functions with a reduction in learning and memory, limited judgment and deficits in emotional control and social behavior. Moreover, aging is a major risk factor for the appearance of several disorders such as cerebrovascular disease, diabetes mellitus, and hypertension...

Stress, a prevalent experience in modern society, is a major risk factor for many psychiatric disorders. Although sensorimotor abnormalities are often present in these disorders, little is known about how stress affects the sensory cortex. Combining behavioral analyses with in vivo synaptic imaging, we show that stressful experiences lead to progressive, clustered loss of dendritic spines along the apical dendrites of layer (L) 5 pyramidal neurons (PNs) in the mouse barrel cortex, and such spine loss closely associates with deteriorated performance in a whisker-dependent texture discrimination task...

BACKGROUND: Metabolic bone disorders frequently occur in patients with chronic liver disease; however, the association between liver fibrosis and bone mineral density in patients with non-alcoholic fatty liver disease (NAFLD) is unclear. METHODS: This is a cross-sectional analysis of 231 asymptomatic subjects (160 women, 61.6 years old) from a university hospital setting, between February 2012 and December 2014. Bone mineral density (BMD) was measured at the lumbar spine, femur neck, and total hip using dual-energy X-ray absorptiometry (DXA)...

Huntington's disease (HD) is a fatal genetic disorder characterized by cell death of medium-sized spiny neurons (MSNs) in the striatum, traditionally attributed to excessive glutamate inputs and/or receptor sensitivity. While changes in corticostriatal projections have typically been studied in mouse models of HD, morphological and functional alterations in thalamostriatal projections have received less attention. In this study, an adeno-associated virus expressing channelrhodopsin-2 under the calcium/calmodulin-dependent protein kinase IIα promoter was injected into the sensorimotor cortex or the thalamic centromedian-parafascicular nuclear complex in the R6/2 mouse model of HD, to permit selective activation of corticostriatal or thalamostriatal projections, respectively...

Indeterminate dendritic cell tumor (IDCT) is an extremely rare hematological disorder with poorly understood pathogenesis. Occasionally encountered by hematologists, unusual presentations of IDCT have never been reported in the spine literature. The authors report a case of a 51-year-old man who presented with progressively worsening axial thoracic back pain radiating to his sides for three months. MRI revealed a large 3-cm enhancing mass at the T9 vertebral body with an exophytic component causing significant canal stenosis...

The emergence of genes implicated across multiple comorbid neurologic disorders allows to identify shared underlying molecular pathways. Recently, investigation of patients with diverse neurologic disorders found TANC1 and TANC2 as possible candidate disease genes. While the TANC proteins have been reported as postsynaptic scaffolds influencing synaptic spines and excitatory synapse strength, their molecular functions remain unknown. Here, we conducted a comprehensive in silico analysis of the TANC protein family to characterize their molecular role and understand possible neurobiological consequences of their disruption...

Brain-derived neurotrophic factor (Bdnf) has been implicated in several neurological disorders including Rett syndrome (RTT), an X-linked neurodevelopmental disorder caused by loss-of-function mutations in the transcriptional modulator methyl-CpG-binding protein 2 (MECP2). The human BDNF gene has a single nucleotide polymorphism (SNP)-a methionine (met) substitution for valine (val) at codon 66-that affects BDNF's trafficking and activity-dependent release and results in cognitive dysfunction. Humans that are carriers of the met-BDNF allele have subclinical memory deficits and reduced hippocampal volume and activation...

Frontotemporal Dementia (FTD) is a neurodegenerative disorder mainly characterised by Tau or TDP43 inclusions. A co-autoimmune aetiology has been hypothesised. In this study, we aimed at defining the pathogenetic role of anti-AMPA GluA3 antibodies in FTD. Serum and cerebrospinal fluid (CSF) anti-GluA3 antibody dosage was carried out and the effect of CSF with and without anti-GluA3 antibodies was tested in rat hippocampal neuronal primary cultures and in differentiated neurons from human induced pluripotent stem cells (hiPSCs)...
