In physiological conditions, adult neurons have low intracellular Cl(-) [(Cl(-))I] levels underlying the γ-aminobutyric acid (GABA)ergic inhibitory drive. In contrast, neurons have high (Cl(-))I levels and excitatory GABA actions in a wide range of pathological conditions including spinal cord lesions, chronic pain, brain trauma, cerebrovascular infarcts, autism, Rett and Down syndrome, various types of epilepsies, and other genetic or environmental insults. The diuretic highly specific NKCC1 chloride importer antagonist bumetanide (PubChem CID: 2461) efficiently restores low (Cl(-))I levels and attenuates many disorders in experimental conditions and in some clinical trials...

Acute central nervous system (CNS) injury, encompassing traumatic brain injury (TBI) and stroke, accounts for a significant burden of morbidity and mortality worldwide, largely attributable to the development of cerebral oedema and elevated intracranial pressure (ICP). Despite this, clinical treatments are limited and new therapies are urgently required to improve patient outcomes and survival. Originally characterised in peripheral tissues, such as the skin and lungs as a neurally-elicited inflammatory process that contributes to increased microvascular permeability and tissue swelling, neurogenic inflammation has now been described in acute injury to the brain where it may play a key role in the secondary injury cascades that evolve following both TBI and stroke...

Traumatic brain injury (TBI) is an expanding public health epidemic with pathophysiology that is difficult to diagnose and thus treat. TBI biomarkers should assess patients across severities and reveal pathophysiology, but currently, their kinetics and specificity are unclear. No single ideal TBI biomarker exists. We identified new candidates from a TBI CSF proteome by selecting trauma-released, astrocyte-enriched proteins including aldolase C (ALDOC), its 38kD breakdown product (BDP), brain lipid binding protein (BLBP), astrocytic phosphoprotein (PEA15), glutamine synthetase (GS) and new 18-25kD-GFAP-BDPs...

This article reviews fluid therapy and medications in pediatric trauma. For resuscitation in the setting of hemorrhagic shock, isotonic crystalloid solution is the first-line agent of choice. Colloid solutions offer no additional benefit, introduce possible increased risks and cost more than crystalloids. Blood products, starting with pRBCs, should be introduced after 20-40 ml/kg of crystalloid has been administered if there is ongoing need for volume replacement. The use of a massive transfusion protocol of 1:1:1 (if >30 kg) or 30:20:20 (if <30 kg) of pRBCs:FFP:platelets is suggested after an initial 30 ml/kg of pRBcs have been administered...

AIM: Increased intracranial pressure following trauma and subsequent possible development of brain death are important factors for morbidity and mortality due to ischemic changes. We aimed to establish the role of ischemic modified albumin (IMA) in the early diagnosis of the process, starting with increased intracranial pressure and ending with brain death. MATERIALS AND METHODS: Eighteen Wistar-Albino rats were divided into three groups; control (CG, n = 6), increased intracranial pressure (ICPG, n = 6), and brain death (BDG, n = 6)...

Neurological trauma can have a devastating effect on activities of daily living. One of the consequences is an increased amount of variability in the system, which can challenge individuals to stay within safe and stable regions of operation. There are multiple sources of movement variability; two of these are neuromotor noise and action-tolerance variability. The amount of neuromotor noise that is uncontrollable can impose limitations on reshaping variability. Action-tolerance variability, which can be reshaped through experience, and neuromotor noise, a certain amount of which cannot be altered, are often conflated when discussing motor variability...

In 5000 BC, South American tribes digged the bones in the living head to seek ways to communicate with the gods, which was primitive trephination and may be the first neurosurgical behavior. In 2600 BC, Imhotep in ancient Egypt took the brain out of the head from the nose, for a better preserve of the mummy, which was a prototype of modern transsphenoidal surgery. And the development of anatomy in ancient Greek laid a solid foundation for neurosurgery. From 500 to 1500 AD, the rise of religion and the occurrence of war, prompted a large number of craniocerebral trauma, which contributed greatly to the early development of neurosurgery as a distinct specialty...

Concussion has been linked to the presence of injurious strains in the brain tissues. Research investigating severe brain injury has reported that strains in the brain may be affected by two parameters: magnitude of the acceleration, and duration of that acceleration. However, little is known how this relationship changes in terms of creating risk for brain injury for magnitudes and durations of acceleration common in sporting environments. This has particular implications for the understanding and prevention of concussive risk of injury in sporting environments...

INTRODUCTION: Higher transfusion ratios of plasma to packed red blood cells (PRBC) and platelets (PLT) to PRBC have been shown to be associated with decreased mortality in major trauma patients. However, little is known about the effect of transfusion ratios on mortality in patients with isolated severe traumatic brain injury (TBI). The aim of this study was to investigate the effect of transfusion ratios on mortality in patients with isolated severe blunt TBI. We hypothesized that higher transfusion ratios of plasma to PRBC and PLT to PRBC are associated with a lower mortality rate in these patients...

BACKGROUND: As the population ages, increasing number of geriatric patients sustain traumatic brain injury (TBI). Communication of accurate prognostic information is crucial for making informed decisions on behalf of such patients. Therefore, the aim of our study was to develop a simple and clinically applicable tool that accurately predicts the prognosis in geriatric TBI patients. METHODS: We performed a 1-y (2011) retrospective analysis of isolated geriatric TBI patients (age ≥65 y, head abbreviated injury score [AIS] ≥ 3, and other body AIS < 3) in the National Trauma Data Bank...

OBJECTIVES: Cognitive defects such as learning and memory impairment are amongst the most repetitious sequelae after sever and moderate traumatic brain injury (TBI). It was suggested that ellagic acid (EA), an innate phenol product, display neuroprotective properties against oxidative and inflammatory damages after brain injury. The object of the current study was therapeutic properties of EA on blood-brain barrier (BBB) interruption and elevated content of TNF-α in brain tissue followed by neurologic aftereffects, cognitive and brain electrophysiology deficits as outcomes of diffuse TBI in rat...

Hypoxia leads to increased red blood cells and blood viscosity at high altitude while moderate trauma increases coagulation in blood. Under the above-mentioned conditions, venous sinus thrombosis is more likely to occur. A patient suffering bilateral acetabular fractures together with the gradual disturbance of consciousness was admitted to our hospital. Though computed tomography arteriogram (CTA) of the brain displayed normal blood vessels; bilateral thalamus and brainstem infarction were found on head computed tomography (CT) and Galen vein thrombosis on cerebral computed tomography venography (CTV)...

General Practitioners frequently see children with medical conditions that may evolve into an emergency if not promptly attended to. The most common emergencies encountered in pediatric office practice are respiratory distress, dehydration, anaphylaxis, seizures and trauma. Assessment of children is sometimes difficult as the signs and symptoms might be subtle and not markedly expressed. Also, normal value of vital signs vary with age, thus their interpretation requires discrete knowledge of age appropriate values...

Diffuse axonal injury is usually caused by head trauma, and patients have significant clinical symptoms during admission to the emergency department. In our case, we present a five-year-old patient who was involved in a car accident. During admission to the emergency department, the patient had no symptoms of trauma. However, 6 h after admission to emergency service, neurological symptoms occurred, and mental status changed. Diffuse axonal injury (DAI) is characterized by diffuse nerve axon injury in the brain and brainstem...
