Ultrastructure of Human Spinal Trabecular Arachnoid

2014

The arachnoid trabecular layer, located internally to the arachnoid layer, is composed of fibers that form the spider web–like trabecular structure found in the subarachnoid space and in the adventitial layer of blood vessels. The arachnoid trabeculae give shape to tubular structures (arachnoid sheaths) for each nerve root and for the spinal cord. Some of these arachnoid trabeculae extend to the pia mater. The trabecular arachnoid is an extremely fragile structure, which can easily be damaged. Because of its fragility, this membrane may be destroyed during dissection and manipulation, so that it is not frequently seen or systematically described. Trabecular arachnoid limits nerve root movem…

Cerebrospinal Fluid Tau Protein Levels and <sup>18</sup>F-Fluorodeoxyglucose Positron Emission Tomography in the Differential Diagnosis o…

2010

<i>Aims:</i> In this study, we aimed to compare cerebrospinal fluid (CSF) levels of total tau (t-tau), phosphorylated tau (p-tau<sub>181</sub>) and positron emission tomography with <sup>18</sup>F-fluorodeoxyglucose (FDG-PET) in the differential diagnosis of Alzheimer’s disease (AD) under clinical conditions. <i>Method:</i> In a cross-sectional, blinded, single-center study, we examined a sample of 75 unselected memory clinic patients with clinical diagnoses of dementia of Alzheimer type (DAT; n = 24), amnestic mild cognitive impairment (MCI; n = 16), other dementias (n = 13) and nondemented controls (n = 22). Discriminative accuracy, sensitiv…

Avoiding lumbar segmental arteries injury in oblique lateral interbody fusion procedure

2020

Lumbar interbody fusion is performed to treat several spinal disorders and involves the insertion of a structural graft into an intervertebral disk space to promote bony arthrodesis. Although the posterior approach to the lumbar spine was long the most frequently adopted surgical strategy to perform fusion, anterior approaches, first introduced in 1906, have recently blossomed. Patient expectations and increasing demands for shorter hospital stay and early recovery have led to more innovative surgical techniques to reduce iatrogenic injury and postoperative morbidity. Depending on the level to be treated, several approaches have been developed, each dealing with peculiar anatomic obstacles:…

Quantifying an Upper Extremity Everyday Task With 3D Kinematic Analysis in People With Spinal Cord Injury and Non-disabled Controls

2021

Objectives: Upper extremity function after spinal cord injury (SCI) is an important factor for performance of activities of daily living. An objective assessment of upper extremity function preferably in purposeful daily tasks is essential in understanding its impact on real-life activities. This study aimed to identify which movement parameters of upper extremity, measured by kinematic analysis during a purposeful daily task, are impaired in people with cervical or thoracic SCI.Materials and Methods: The study included 29 adults (mean 59.5 years, 9 women and 20 men) with cervical (n = 19) or thoracic (n = 10) established complete (n = 15) or incomplete (n = 14) SCI, and 54 non-disabled con…

Vertebral fractures, function and cognitive status in osteoporotic hip fractured women: The FOCUS study

2017

Introduction Osteoporosis is characterized by low bone mass and microarchitectural modifications of bone tissue, with a consequent increase in fragility fractures. Vertebral fractures (VF) are the most prevalent osteoporotic fractures and osteoporotic hip fractures are the most serious complication of osteoporosis. The objectives of the present study were to determine the prevalence of VF in osteoporotic hip fractured women and to evaluate their association with pre-existing factors such as activities of daily living, quality of walking, numbers of falls, cognitive aspects and comorbidities. Material and methods Twenty-five departments of Orthopaedics, Rehabilitation and Geriatrics particip…

Emergency surgery in a patient with large spontaneous spinal epidural hematoma determining excellent neurological recovery: Review of the literature

2014

Study design: Case report. Objectives: We report a case of a 75-year-old woman suffering from voluminous idiopathic spontaneous spinal epidural hematoma (SSEH) that was rapidly diagnosed and successfully treated. Methods: Clinical presentation was characterized by sudden and intense back pain that rapidly evolved into plegia of the right leg and severe paresis of the left leg. Hypoesthesia below T6 and urinary retention were also present. Magnetic resonance imaging showed a significant posterior spinal compression from T6 through L3 caused by an epidural hematoma that involved 10 metameric levels, extending for ∼20 cm, with a maximum thickness of 1.6 cm from T12 to L1. Results: Within 12 h,…

Motor asymmetry attenuation in older adults during imagined arm movements

2014

International audience; Laterality is an important feature of motor behavior. Several studies have shown that lateralization in right-handed young adults (i.e., right versus left arm superiority) emerges also during imagined actions, that is when an action is internally simulated without any motor output. Such information, however, is lacking for elderly people and it could be valuable to further comprehend the evolution of mental states of action in normal aging. Here, we evaluated the influence of age on motor laterality during mental actions. Twenty-four young (mean age: 24.7 +/- 4.4 years) and 24 elderly (mean age: 72.4 +/- 3.6 years) participants mentally simulated and actually execute…

Gait Impairment in a Rat Model of Focal Cerebral Ischemia

2012

The availability of proper tests for gait evaluation following cerebral ischemia in rats has been limited. The automated, quantitative CatWalk system, which was initially designed to measure gait in models of spinal cord injury, neuropathic pain, and peripheral nerve injury, is said to be a useful tool for the study of motor impairment in stroke animals. Here we report our experiences of using CatWalk XT with rats subjected to transient middle cerebral artery occlusion (MCAO), during their six-week followup. Large corticostriatal infarct was confirmed by MRI in all MCAO rats, which was associated with severe sensorimotor impairment. In contrast, the gait impairment was at most mild, which i…
