BACKGROUND: Traumatic spinal subarachnoid hematoma, associated or not to a concurrent subdural hematoma has rarely been described. The evolution of such hematomas is heterogeneous. This study aims at defining the most accurate management which is currently not standardized. CASE DESCRIPTION: A 20-year-old man, victim of a high kinetic road accident five days before, suffering from several non-neurologic non-surgical vertebral fractures, complained of a sudden dorso-lumbar pain irradiating to his lower limbs...

BACKGROUND: Traumatic spinal injury (TSI) results from injury to bony, ligamentous and/or neurological structures of the spinal column and can cause significant morbidity and mortality. The global burden of TSI is poorly understood, so we performed a systematic review and meta-analysis to estimate the global volume of TSI. METHODS: We performed a systematic review through PubMed, Embase and Cochrane Databases on TSI studies published from 2000 to 2016. Collected data were used to perform a meta-analysis to estimate the annual incidence of TSI across World Health Organization (WHO) regions and World Bank income groups using random effect models...

BACKGROUND: Acute Spinal Cord Injury (ASCI) is still having substantial morbidity and mortality despite of advanced therapeutics. Major obstacles are paucity of monitoring tools or biomarkers for severity determination, recovery and prognostication. A prospective case control pilot study with serum 1 H NMR spectroscopic metabolic profiling was carried out to evaluate metabolites perturbations and its relationship with recovery and to see role of stem cells in facilitating neurological recovery...

Importance: The association between pemphigus and neurologic diseases was not evaluated systematically in the past. In a recent uncontrolled cross-sectional study, Parkinson disease was found to be significantly associated with pemphigus; in the same study, epilepsy had a nonsignificant association with pemphigus. Several case reports have suggested that pemphigus coexists with multiple sclerosis and dementia. Objective: To estimate the association between pemphigus and 4 neurologic conditions (dementia, epilepsy, Parkinson disease, and multiple sclerosis), using one of the largest cohorts of patients with pemphigus...

Here, we present a case of a 31-year-old man with progressive cognitive decline, ataxia, and dystonia. Extensive laboratory, radiographic, and targeted genetic studies over the course of several years failed to yield a diagnosis. Initial whole exome sequencing through a commercial laboratory identified several variants of uncertain significance; however, follow-up clinical examination and testing ruled each of these out. Eventually, repeat whole exome sequencing identified a known pathogenic intronic variant in the NPC1 gene (NM_000271...

BACKGROUND CONTEXT: There is a broad spectrum of complications during or after surgical procedures, with differing incidences reported in the published literature. Heterogeneity can be explained by the lack of an established evidence-based classification system for documentation and classification of complications in a standardized manner. PURPOSE: To identify predictive risk factors for peri- and early post-operative morbidities in spine surgeries of different complexities in a large cohort of consecutive patients...

Demand-controlled deep brain stimulation (DBS) appears to be a promising approach for the treatment of Parkinson's disease (PD) as revealed by computational, pre-clinical and clinical studies. Stimulation delivery is adapted to brain activity, for example, to the amount of neuronal activity considered to be abnormal. Such a closed-loop stimulation setup might help to reduce the amount of stimulation current, thereby maintaining therapeutic efficacy. In the context of the development of stimulation techniques that aim to restore desynchronized neuronal activity on a long-term basis, specific closed-loop stimulation protocols were designed computationally...

BACKGROUND: Ischemic stroke is a multifactorial neurologic injury that causes mortality and disability worldwide. Poststroke depression is the most important neuropsychiatric consequence of stroke. Brain-derived neurotrophic factor is a neurotrophin family member that plays key role in regulating neuron survival and differentiation. Studies found a polymorphism in brain-derived neurotrophic factor gene (rs6265) may associate with the ischemic stroke and poststroke depression risk. However, the results are inconclusive and inconsistent...

Neuronal ceroid lipofuscinoses (NCLs) are heterogenic inherited lysosomal storage diseases that have been described in a number of species including humans, sheep, cattle, cats and a number of different dog breeds, including Salukis. Here we present a novel genetic variant associated with the disease in this particular breed of dog. In a clinical case, a Saluki developed progressive neurological signs, including disorientation, anxiety, difficulties in eating, seizures and loss of vision, and for welfare reasons, was euthanized at 22 months of age...

Background: Volume estimation of brain is important for many neurological applications. It is necessary in measuring brain growth and changes in brain in normal/abnormal patients. Thus, accurate brain volume measurement is very important. Magnetic resonance imaging (MRI) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. Stereology method is a good method for estimating volume but it requires to segment enough MRI slices and have a good resolution...
