Among the various disorders that manifest with gait disturbance, cognitive impairment, and urinary incontinence in elderly population, idiopathic normal pressure hydrocephalus (iNPH) is becoming of great importance. The first edition these guidelines for management iNPH was published 2004, second 2012, to provide a series timely, evidence-based recommendations related iNPH. Since last edition, clinical awareness has risen dramatically, basic research efforts on have increased significantly....
<h3>Objectives</h3> This cross-sectional survey explored the characteristics and outcomes of direct oral anticoagulant (DOAC)–associated nontraumatic intracerebral hemorrhages (ICHs) by analyzing a large nationwide Japanese discharge database. <h3>Methods</h3> We analyzed data from 2,245 patients who experienced ICHs while taking anticoagulants (DOAC: 227; warfarin: 2,018) were urgently hospitalized at 621 institutions in Japan between April 2010 March 2015. compared DOAC- warfarin-treated...
High gamma activity (HGA) is a crucial biomarker for functional brain mapping, particularly in sensorimotor areas, to preserve functionality after surgeries. HGA mapping paradigms typically involve multiple task blocks alternating with resting (R) conditions, where each block comprises consecutive tasks under nonresting (NR) conditions. However, the repetitive nature of these may lead attenuation due repetition suppression, potentially compromising accuracy mapping. This study tests...
Management of intracranial epidural abscess (ICEA) typically requires a combination surgical drainage and antibiotic therapy. However, the indications for neurosurgical ICEA have not been well established by evidence-based data remain controversial. This article describes case that enlarged during therapy but was managed successfully without drainage. A 13-year-old boy admitted to authors' hospital with 6-day history high fever, fatigue, headache. Computed tomography magnetic resonance...
It is often difficult to make a correct diagnosis of ring-like enhanced lesions on Gd-enhanced MR brain images. To differentiate these using proton spectroscopy (1H-MRS), we retrospectively evaluated the correlation between 1H-MR spectra and histopathological findings. We obtained from in 45 patients, including metastasis (n = 19), glioblastoma 10), radiation necrosis 7), abscess 5), cerebral infarction 4). The rate misdiagnosis was found be lowest at threshold level 2.48 for (choline...
The 3-meter Timed Up and Go test (TUG) is a reliable quantitative for assessment of gait balance. We aimed to establish an optimal threshold TUG at the tap predicting outcomes 12 months after shunt surgery in patients with idiopathic normal pressure hydrocephalus (iNPH).The was measured total 151 possible iNPH before surgery. Among them, 81 underwent ventriculoperitoneal implantation (SINPHONI) 70 lumboperitoneal (SINPHONI-2). areas under curve (AUCs), sensitivities, specificities...
The present research reports thermoset nanocomposites reinforced with cotton fibres extracted from textile waste called as ‘shoddy’ and graphite oxide nanoparticles filler. oriented fibre web of shoddy was produced by using the carding machine it used reinforcement. epoxy composites four different volume fraction values namely 0.1, 0.2, 0.3 0.4 were developed. These characterized mechanical properties to optimize fraction. Further, developed incorporating filler in weight percentages, 0.3,...
Object. The goal of this study was to investigate the usefulness proton ( 1 H) magnetic resonance (MR) spectroscopy evaluate response metastatic brain tumors stereotactic radiosurgery (SRS) in comparison with Gd-enhanced MR imaging and single-photon emission computerized tomography administration thallium-201 chloride 201 TlCl-SPECT). Methods. Forty patients a total 47 were evaluated. primary lesion identified all cases. Stereotactic effective 37 lesions. All examined using before after SRS....
OBJECTIVE The study aim was to assess the influence of presurgical clinical symptom severity and disease duration on outcomes shunt surgery in patients with idiopathic normal-pressure hydrocephalus (iNPH). authors also evaluated cerebrospinal fluid tap test as a predictor improvements following surgery. METHODS Eighty-three (45 men 38 women, mean age 76.4 years) underwent lumboperitoneal surgery, were until 12 months Risks for poor quality life (Score 3 or 4 modified Rankin Scale [mRS])...
Objective: To identify a neurochemical basis for the hypothesis that an aberrant cortico‐subcortical circuit underlies obsessive–compulsive disorder (OCD). The white matter was also investigated because of recent research which suggests altered connectivity axons. Method: Using 3‐Tesla magnetic resonance spectroscopy, relative concentrations N ‐acetylaspartate (NAA) and choline‐containing compounds (Cho) to creatine/phosphocreatine (Cr) were measured in anterior cingulate, basal ganglia,...
The cerebrospinal fluid tap test for idiopathic normal pressure hydrocephalus (iNPH) is one of the good predictors shunt treatment, although this has a low sensitivity. We aimed to identify key parameters that could be used improve sensitivity.During 2010-2011, we recruited and then followed 93 patients with possible iNPH 12 months after shunt. Among them, 82 were finally enrolled in study. modified Rankin Scale, grading scale, several quantitative measurements evaluated at entry, test,...
<b><i>Background and Purpose:</i></b> The optimal use of antiplatelet therapy for intracranial branch atheromatous disease (BAD) is not known. <b><i>Methods:</i></b> We conducted a prospective multicenter, single-group trial 144 consecutive patients diagnosed with probable BAD. All were treated within 12 h symptom onset to prevent clinical progression using dual cilostazol plus one oral drug (aspirin or clopidogrel). Endpoints progressive BAD...
Object The authors of previous studies based on diffusion tensor imaging have indicated that there are two types peritumoral edema—namely, edema with preserved structural integrity the glial matrix and compromised matrix. this study hypothesized functionality glutamate (Glu)–glutamine shuttle, a vital neuron–glia interaction, may be differentially affected by edema. They tested hypothesis using proton magnetic resonance (MR) spectroscopy 3.0-tesla system is capable quantifying Glu without...
We clearly demonstrated a fine morphology of the tumbular structures antigenically related to reovirus-like particles associated with acute nonbacterial gastroenteritis in young children. The tubular caplike structure on each end seemed be complete forms, 75 80 nm width and approximately 1,000 length.
The enteropathogenicity of Aeromonas strains that showed mannose-resistant adhesion to INT407 cells was evaluated by infecting Caco-2 and observing them light electronmicroscopy. Five six adhered in large numbers the presence mannose caused cytopathic effects. Two spp. seemed invade cells, as membrane-bound bacteria were seen within cytoplasm these cells; however, staining acridine orange-crystal violet appeared show intracellular fluorescent three strains. Fimbriae did not appear play an...
