Acute disseminated encephalomyelitis (ADEM) is an acute inflammatory demyelinating disease of central nervous system, and is related to allergic or immune-mediated reaction to systemic viral infection or vaccination, which is usually self limited monophasic illness. As the clinical manifestations or laboratory findings is nonspecific, it is diagnosed by brain magnetic resonance imaging (MRI) showing multiple foci of increased T2 signal within white matter. We report the clinical and radiologic imaging findings in a 36-year-old man in whom acute disseminated encephalomyelitis developed after serologically proven herpes infection combined with liver abscess. His clinical course, despite without corticosteroid or plasmapheresis because of liver abscess, was shown spontaneous remission.

PURPOSE: Although platelet-rich plasma (PRP) potentiate the wound healing activity of adipose-derived stem cells (ADSCs), its effect cannot be sustained for a prolonged period of time due to short duration of action. This led us to design and produce platelet-rich fibrin (PRF), in an effort to develop a tool which lasts longer, and apply it on wound healing. METHODS: Two symmetrical skin defects were made on the back of seven nude mice. ADSCs were applied to each wound, combined with either PRP or PRF. The wound area was measured over 14 days. By day 16, the wound was harvested and histologic analysis was performed including counting of the blood vessel. RESULTS: The healing rate was more accelerated in PRP group in the first 5 days (p<0.05). However, PRF group surpassed PRP group after 6 days (p<0.05). The average number of blood vessels observed in the PRF group was 6.53 +/- 0.51, compared with 5.68 +/- 0.71 for the PRP group. CONCLUSION: PRF exerts a slow yet pervasive influence over the two-week course of the wound healing process. Thus, PRF is probably more beneficial for promoting the activity of ADSCs for a sustained period of time.

PURPOSE: This study was conducted to explore the professional identity of elementary school health teachers. METHODS: In-depth interviews with fifteen elementary school health teachers were conducted from July 2010 to August 2012. Qualitative data collected by the researcher including transcription and field notes were analyzed through an adapted methodology based on the Grounded Theory of Strauss and Corbin. RESULTS: Fifteen categories, 35 sub-categories and 120 concepts were obtained. The key category that was consistently maintained in identity formation was 'keeping themselves being a teacher providing nursing' which has three styles, 'focusing on health education', 'combining nursing and education' and 'focusing on providing nursing care'. CONCLUSION: Results of this study will provide basic information for preparing manuals regarding the range of activities in school health teachers' jobs, improving promotion and merit payment systems for school health teachers, creating support programs for them, and contributing to the formation and establishment of their professional identity.

The traumatic middle meningeal arteriovenous fistula is a rare condition complicated from head injury and usually found incidentally by carotid angiography. A few articles reported previously showed this condition if formed due to tearing of the walls of middle meningeal vessels by skull fracture and regarded as a wonderful defence mechanism keeping from a big intracranial hematoma. We have encountered 3 cases of them, all of which were accompanied by skull fracture. On of them had a big epidural hematoma and others only small amount. We show these cases in detail with the review of literatures.

Torsade de Points is unique polymorphic ventricular tachycardia associated with QT interval prolongation. The mechanism of Torsade de Points was not defined exactly but triggered activity associated with afterdepolarization and/or dispersion of repolarization were known possible explanation. Torsade de points is most often induced by various drugs such as antiarrythmic agents, antipsychotic agents, antibiotis, and antihistamines. Astemizole(Hismanal(R)) and Terfenadine among antihistamines are reported that cause leading to a Torsade de Points. We experienced the case of Torsade de Points which was induced with Piprinhydrinate(Diphenylpyraline, Plokon(R)), antihistamine of ethanolamine derivatives, expressed recurrent syncope and dizziness in a young lady.

PURPOSE: The purpose of this study was to compare the survival of patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC) undergoing concurrent chemoradiotherapy (CRT) alone with that of patients undergoing induction chemotherapy (IC) using docetaxel, cisplatin, and 5-fluorouracil (TPF) followed by CRT. MATERIALS AND METHODS: A search of the PubMed, EMBASE, and Cochrane Library databases was performed in April 2015 and abstracts from the American Society of Clinical Oncology meetings (2008-2014) were reviewed. Summaries of the results were pooled using a fixed-effect model, and the risk of bias was evaluated using the Cochrane tool. RESULTS: A total of six relevant trials comprising 1,280 patients were identified. There was no statistically significant overall survival (OS) advantage for TPF prior to CRT (TPF/CRT) over CRT alone (hazard ratio [HR] 0.92; 95% confidence interval [CI], 0.79 to 1.09; p=0.339). Progression-free survival (PFS) was significantly longer in the TPF/CRT arms (HR, 0.82; 95% CI, 0.70 to 0.95; p=0.009). Patients with non-oropharyngeal LA-HNSCC obtained the greatest OS and PFS benefits from TPF (HR, 0.68; 95% CI, 0.47 to 0.99; p=0.043 and HR, 0.67; 95% CI, 0.48 to 0.94; p=0.022, respectively). The complete response rate was significantly increased (risk ratio [RR], 1.34; 95% CI, 1.14 to 1.56; p < 0.001), and the distant metastasis rate tended to decrease (RR, 0.65; 95% CI, 0.40 to 1.04; p=0.071) in the TPF/CRT arms. CONCLUSION: IC with TPF followed by CRT is not superior to CRT alone for OS. However, PFS and the complete response rate were significantly improved in the TPF/CRT arms. TPF/CRT for patients with nonoropharyngeal LA-HNSCC provided clear survival advantages.

A 48-year-old woman presented with right visual aura evolving into versive and clonic seizures. The seizures were controlled not by anticonvulsants but bynormalization of blood sugar and not by anticonvulsants. T2-weighted MRI (T2WI) showed subcortical hypointensity and cortical hyperintensity with a low apparent diffusion coefficient (ADC) value in left occipital area, which reversed into a high ADC value at in follow-up images. Serial MRIs including diffu-sion- weighted images seemed to reveal tissue injury after partial status epilepticus and regional ischemia associated with non-ketotic hyperglycemia.

Molecular mechanism of nuclear factor-kappaB(NF-kappaB) in the atherosclerosis has been unclear. Recently, NF-kappaB activating function of tissue transglutaminase (tTGase), multifunctional calcium-dependent transamidation enzyme, have been reported in the various tissues like neuroglia. In this report, we investigated the immunoreactivity of tTGase at the human atherosclerotic coronary artery, and examined the effect of tTGase on the well-known proatherogenic NF-kappaB pathway using tTGase-overexpressed cells. Immunohistochemical studies on autopsy samples showed that immunoreactivity of tTGase was markedly elevated in the neointimal tissues of atherosclerotic coronary arteries with progression of disease. Immunohistochemical staining also demonstrated that phosphorylated I-kappaB was activated in the atherosclerotic vessel wall. In vitro study using rat cardiomyoblast (H9c2) and tTGase-overexpressed H9c2 showed that activated tTGase enhanced the phosphorylation of I-kappaB, and this activation was inhibited by tTGase specific inhibitors. These findings suggest that cytosolic tTGase may serve as an activator of NF-kappaB.
