Deep brain stimulation (DBS) of the subthalamic nucleus (STN) is the reference technique in Parkinson's disease (PD) at different stages of complications. Some patients cannot afford DBS due to anticoagulation or comorbidities or due to pecuniary reasons. Radiosurgery is a minimally invasive stereotactic technique, with no craniotomy and subsequently no risk of bleeding or infection. Its good safety efficacy profile has been established in the treatment of tremor, and the postoperative care issues are simple with a much shorter hospital stay (mean 48 h)...

While the etiology of Alzheimer's disease (AD) is still unknown, an increased formation of amyloid-β (Aβ) peptide and oxidative processes are major pathological mechanism of the disease. The interaction of Aβ with free heme leads to the formation of peroxidase-active Aβ-heme complexes. However, enzyme-kinetic data and systematic mutational studies are still missing. These aspects were addressed in this study to evaluate the role of Aβ-heme complexes in AD. The enzyme-kinetic measurements showed peroxidase-specific pH- and H2O2-dependencies...

Intraventricular Hemorrhage (IVH) is the leading cause of neurological and cognitive impairment in preterm neonates with an incidence that increases with increasing prematurity. In the present study, we tested how preterm neonates with IVH react to external stimulation (i.e. speech syllables). We compared their neural responses measured by electroencephalography (EEG), and hemodynamic responses measured by functional near-infrared spectroscopy (fNIRS), with those of healthy preterms. A neural response to syllables was observed in these infants, but did not induce a vascular response in contrast with healthy neonates...

Ulcerative colitis (UC) is a chronic and debilitating disorder, characterized by inflammation of the colonic mucosa. UC can be considered a systemic disorder but UC-related manifestations in the central nervous system (CNS) are quite rare. A 29-year-old man was admitted to the emergency department with repeated generalized tonic-clonic (GTC) type seizures. Based on brain CT, brain metastasis or hemorrhagic infarct was suspected. Diffusion-weighted image of brain MRI showed high signal in the left thalamus and heterogenous enhancement in the right parietal and left frontal lobes...

Traumatic brain injury (TBI) is an important health issue with high mortality. Various complications of physiological and cognitive impairment may result in disability or death after TBI. Grouping of these complications could be treated as integrated post-TBI syndromes. To improve risk estimation, grouping TBI complications should be investigated, to better predict TBI mortality. This study aimed to estimate mortality risk based on grouping of complications among TBI patients. Taiwan's National Health Insurance Research Database was used in this study...

Context Hemorrhage is one of the potentially fatal complications of tracheostomy. A rare but lethal cause of tracheostomy related bleeding is hemorrhage from the innominate artery. This occurs following tracheo-innominate artery fistula (TIF) formation, which is associated with a mortality rate of more than 85%. Here, we report the case of an individual with tetraplegia and a tracheostomy who died as a result of innominate artery hemorrhage. This case highlights the possible causes and interventions associated with this complication, and provides insight into tracheostomy related bleeding in patients with spinal cord injury (SCI)...

Xenon (Xe), a noble gas, has promising neuroprotective properties with no proven adverse side-effects. We evaluated neuroprotective effects of Xe delivered by Xe-containing echogenic liposomes (Xe-ELIP) via ultrasound-controlled cerebral drug release on early brain injury following subarachnoid hemorrhage (SAH). The Xe-ELIP structure was evaluated by ultrasound imaging, electron microscopy and gas chromatography-mass spectroscopy. Animals were randomly divided into five groups: Sham, SAH, SAH treated with Xe-ELIP, empty ELIP, or Xe-saturated saline...

This study was to investigate the alterations of serum copper homeostasis after hypertensive intracerebral hemorrhage (ICH), which is not yet clear. We recruited 85 hypertensive ICH patients and determined their serum levels of total copper (TCu), small molecule copper (SMC), and ceruloplasmin (Cp). Sera from 32 healthy persons and 12 primary hypertension patients were collected and analyzed as well. Serum TCu levels in ICH patients were tested at three time points (on admission, day 3, and day 7) and found to be higher than that in hypertension patients (p < 0...

A 74-year-old woman who exhibited drowsiness was referred to our hospital. Enhanced head magnetic resonance imaging (MRI) revealed multiple ring-enhancing lesions and lesions showing partial mild hemorrhaging. The patient gradually progressed to a comatose condition with notable brain deterioration of unknown cause on follow-up MRI. On day nine, the patient inexplicably died, although brain herniation was suspected. Autopsy and histopathology revealed numerous amoebic trophozoites in the perivascular spaces and within the necrotic tissue...

High mobility group box-1 (HMGB1), a representative damage-associated molecular patterns (DAMPs), has been reported to be involved in many inflammatory diseases. To validate HMGB1 as a target molecule of inflammatory diseases and to examine the effects of inhibition of HMGB1 on the diseases, we raised anti-HMGB1 monoclonal antibody (mAb) neutralizing extracellular HMGB1 and characterized it. We report the effects of anti-HMGB1 mAb on brain infarction, brain hemorrhage, brain trauma, epilepsy and neuropathic pain using animal models...

Prothymosin alpha (ProTα) has been identified as an anti-necrotic factor from the conditioned medium of primary cultured of rat cortical neurons under the serum-free starving condition. ProTα is released in a non-vesicular manner from neurons or astrocytes by the help of cargo protein S100A13. Thus released ProTα is found to have robustness roles in the brain under the condition of neuronal necrosis or apoptosis. ProTα inhibits necrosis by plasma membrane-translocation of glucose transporters endocytosed by ischemia/starving stress, through an activation of unidentified G protein-coupled receptor and protein kinase Cβ...

INTRODUCTION: Natriuretic peptides are ubiquitously used for diagnosis, follow-up and prognostic assessment in various heart conditions. N-terminal pro-brain natriuretic peptide (NT-proBNP) correlates with aortic stenosis severity, however its significance after transcatheter aortic valve implantation (TAVI) is not well established. AIM: We aimed to assess the prognostic value of NT-proBNP at one year in patients undergoing TAVI. METHODS: This single-center retrospective analysis included 151 patients in whom both baseline and one-month post-procedure NT-proBNP were measured, from 206 consecutive patients undergoing TAVI between November 2008 and December 2014...

Subarachnoid hemorrhage (SAH) represents a major health problem in Western society due to high mortality and morbidity, and the relative young age of patients. Currently, efficacious therapeutic options are very limited. Mesenchymal stem cell (MSC) administration has been shown to improve functional outcome and lesion size in experimental models of stroke and neonatal hypoxic-ischemic brain injury. Here we studied the therapeutic potential of intranasally administered bone marrow-derived MSCs relatively late post-insult using a rat endovascular puncture model for SAH...

BACKGROUND: Major blunt chest injury usually leads to the development of retained hemothorax and pneumothorax, and needs further intervention. However, since blunt chest injury may be combined with blunt head injury that typically requires patient observation for 3-4 days, other critical surgical interventions may be delayed. The purpose of this study is to analyze the outcomes of head injury patients who received early, versus delayed thoracic surgeries. MATERIALS AND METHODS: From May 2005 to February 2012, 61 patients with major blunt injuries to the chest and head were prospectively enrolled...
