Leucine-rich glioma inactivated 1 (LGI1) was recently identified as a target protein in autoimmune synaptic encephalitis, a rare condition associated with autoantibodies against structures in the neuronal synapse. Studies dealing with LGI1 are small in number and the various outcomes of different therapeutic regimens are not well studied. Here, we analyzed(More)
Bounding volume hierarchies (BVHs) are widely used to accelerate the performance of various geometric and graphics applications. These applications include ray tracing, collision detection, visibility queries, dynamic simulation, and motion planning. These applications typically precompute BVHs of input models and traverse the BVHs at runtime in order to(More)
Amphiphysin antibody causes paraneoplastic stiff-person syndrome and can also result in a variety of neurological manifestations. Here, we investigated the clinical spectrum of 20 patients with non-stiff anti-amphiphysin syndrome and their responses to immunotherapy. The most common neurological manifestation was limbic encephalitis (n=10), followed by(More)
A considerable portion of autoimmune encephalitis (AE) does not respond to conventional immunotherapies and subsequently has poor outcomes. We aimed to determine the efficacy of tocilizumab, an anti-interleukin-6 antibody, in rituximab-refractory AE compared with other treatment options. From an institutional cohort of AE, 91 patients with inadequate(More)
The World Health Organization reported that pesticide selfpoisoning is the most important method of suicide worldwide [1,2]. Among pesticides, organophosphate compounds and pyrethroids induce neuronal excitotoxicity in the central nervous system and wide spectrum of symptoms [3,4]. We report a case of pesticide selfpoisoning where the patient initially(More)
Genome-wide profiling has revealed that eukaryotic genomes are transcribed into numerous non-coding RNAs. In particular, long non-coding RNAs (lncRNAs) have been implicated in various human diseases due to their biochemical and functional diversity. Epileptic disorders have been characterized by dysregulation of epigenetic regulatory mechanisms, and recent(More)
Encephalitis associated with anti-γ-aminobutyric acid-B (GABAB) receptor antibodies has been identified recently. However, only a few cases have been reported to date and its clinical manifestations and prognosis have not been investigated systematically. We identified five cases of GABAB encephalitis in Korea. Here we present the clinical features,(More)
BACKGROUND AND PURPOSE Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is the most common type of autoimmune synaptic encephalitis and it often responds to treatment. We analyzed the clinical characteristics of anti-NMDAR encephalitis in Korea. METHODS Serum and/or cerebrospinal fluid (CSF) of adult patients (aged ≥18 years) with encephalitis(More)
We present a cache-oblivious ray reordering method for ray tracing. Many global illumination methods such as path tracing and photon mapping use ray tracing and generate lots of rays to simulate various realistic visual effects. However, these rays tend to be very incoherent and show lower cache utilizations during ray tracing of models. In order to address(More)
OBJECTIVE To determine efficacy and safety of rituximab treatment as a second-line immunotherapy treatment for autoimmune limbic encephalitis (ALE) and to determine factors associated with functional improvement and favorable outcome following rituximab treatment. METHODS We recruited 80 patients with ALE who were treated with rituximab as a second-line(More)
