Biatrial myxomas are extremely rare, and only two cases have been reported in Korea so far. We report a 60-year-old male patient with decreased mentality due to embolization from myxoma. In this case, two pedicles grew into both atrial chamber separately from the different origins at the atrial septum. The patient underwent emergency operation immediately after the diagnosis by an echocardiography.

The cerebral vasospasm after clipping surgery of unruptured aneurysm is uncommon. A 44-year-old man with unruptured left middle cerebral artery[MCA] aneurysm had clipping surgery. From the third postoperative day, he presented with drowsy mentality, dysphasia and right hemiparesis. Computed tomographic scans showed low density area in frontotemporal lobe and midline shift. Transfemoral cerebral angiography revealed severe vasospasm in supraclinoid internal carotid artery, anterior cerebral artery, and MCA on the operative side. We performed left frontotemporoparietal craniectomy and hypertensive-hypervolemic therapy. He recovered without neurological deficits but for dysphasia. Neurosurgeon should be alert to the possibility of vasospasm after clipping surgery even in case of unruptured cerebral aneurysm.

Hypoglycemic encephalopathy is a rare problem among diabetic patients who are receiving treatment with insulin or other glucose-lowering drugs. The MRIs of patients with hypoglycemic encephalopathy commonly show scattered lesions in the cerebral cortex, hippocampus and basal ganglia, but lesions in the cerebellum or brain stem are extremely rare. A 44-year-old alcoholic woman without diabetes was admitted with a semicomatose mentality and seizure with severe hypoglycemic encephalopathy with extensive brain lesions seen on MRI at the middle cerebellar peduncle and midbrain, as well as in the other brain areas.

Japanese-B viral encephalitis (JE) usually has a monophasic illness pattern. A 45-year-old woman in an altered mentality had improved over 1 month. About 1 week after the initial improvement, the patient became comatose with aggravated EEG and MRI findings. Assays of cerebrospinal fluid and serum were positive for the IgM antibody to Japanese-B virus. After intravenous immunoglobulin (IVIG) infusion, the patient recovered. We report a patient with JE who showed a biphasic illness pattern and recovered after IVIG therapy.

Periodic lateralized epileptiform discharges (PLEDs) had been debated whether it is ictal or non-ictal phenomenon. As most of PLEDs occur in patients with acute structural lesions, some epileptologists prefer PLEDS as a non-ictal phenomenon, rather an obscure epiphenomenon of etiological diseases. But, almost half of the patients with PLEDs do not have acute structural lesions in the brain and metabolic disorders or old CNS lesions may cause PLEDs and even more, no brain lesion was identified in some patients. There are many data supporting PLEDs as ictal phenomena. Occurrence of PLEDs usually accompanied by decreased mentality and is improved as PLEDs disappeared. Current SPECT study showed marked hyperperfusion in the lesion side of PLEDs, that is striking evidence of PLEDs as ictal phenomena. Also careful review of EEG with PLEDs revealed it is a dynamic process rather than a static state. Despite of these evidences, as PLEDs are an end-stage of animal status epilepticus models, it may be a transition of ictal to interictal state.

Supporting communications among users, Social Network has encouraged various information flows through relationships among them. This paper studies on mentality or attitude of Social Network Services (SNS for short) users, on the basis of Technology Acceptance Model (TAM for short) and then proposes so-called TAMS, Technology Acceptance Model for Social Network Services. SNS users make full use of SNS as channels in order to create, expand, and obtain some information related to personal concerns. We will research on how the benefits that users get by using SNS exert influence on user-perceived usability. The SNS-using benefits focus on relationship benefits that are formed by interactions among users. Provided that perceived usability affects mental or informational benefits according to involvement of SNS users, we will check how perceived usability or ease of use is connected to brand attitude.

Amitraz is a formamidine-derived insecticide and acaricide which is commonly used throughout the world. Amitraz intoxication is mediated through ${\alpha}_2$ adrenergic receptor agonist effects, similar to those of the ${\alpha}_2$ agonist clonidine. We report a case of a patient who experienced coma and hypotension after amitraz ingestion. A 37-year-old woman visited the ER with symptoms of vomiting and altered mental state. She had ingested a mouthful of liquid amitraz concentrate (12.5%), which rapidly led to vomiting, hypotension, bradycardia, hyperglycemia, and mental stupor. Supportive treatment, including mechanical ventilation and administration of inotropics, resulted in full recovery within four days.

Objectives: We here do propose that cancer treatment moxibustion should be used both direct moxibustion and electro-moxibustion simultaneously. Methods: Electro-moxibustion is used in $38^{\circ}C$ low-heat level and it will help to raise parasympathetic and to bring stability of mentality. Direct moxibustion is used in rice size and will help to raise sympathetic and to induce visceral reflection and visceral motion. Results: Electro-moxibustion increased average body heat by $+2.51^{\circ}C$ and kept patients from suffering pains. Direct moxibustion increased average body heat by $+1.2^{\circ}C$ by meridian point-internal organs reflection. Conclusions: Both use of direct moxibustion and electro-moxibustion simultaneously will be superior to the only either direct moxibustion or electro-moxibustion for cancer treatment moxibustion.

We present a case of hydrocephalus as the primary manifestation of neurosarcoidosis. Sarcoidosis is a rare disease in Korea and its incidence is much lower than that of tuberculosis. Diagnosis is made by pathologic findings and by exclusion of other granulomatous disorders. Neurosarcoidosis is observed in approximately 5% of sarcoidosis. Its common manifestations are facial palsy (50% of patients with neurosarcoidosis) and optic neuritis. Hydrocephalus is a very uncommon reported finding. Although the typical presentation of sarcoidosis such as facial palsy is not a diagnostic dilemma, more atypical presentations such as hydrocephalus with altered mentality in a tuberculosis patient can lead to a misdiagnosis.
