A previously healthy 3-year-old girl was admitted to the Department of Pediatrics in Severance Hospital with sudden symptoms of melena. The vital signs were stable, and splenomegaly was found in a physical examination. The patient had moderate thrombocytopenia. There was no evidence of autoimmune disease. A upper gastrointestinal endoscopy and esophagogram showed a varix on the lower esophagus. Coarse liver parenchymal echoes and increased periportal echogenicity were seen on a Doppler sonogram. The velocity of the portal vein mildly increased. Magnetic-resonance-cholangiopancreatogram (MRCP) demonstrated normal portal structures. A sono-guided liver biopsy was performed, but the pathological findings were unremarkable. Based on these findings, we diagnosed the patient with idiopathic portal hypertension. The patient was discharged and was treated with oral beta blocker. We report a case of idiopathic portal hypertension with a brief review of the literature.

Purpose: The purpose of this study was to develop a computer access assessment tool for persons with physical disabilities and to evaluate reliability and validity. Methods: We developed a computerized Computer access Assessment Program (CAP) through many kinds of literature review and tools analysis for evaluation of computer access, task analysis of fundamental input devices operation and expert review. The CAP data were obtained from 105 normal university students and 16 students with physical disabilities. The test items of CAP are composed of four timed mouse tasks, four timed keyboard tasks, and a timed scanning task. Thus, the software measures user performance in skills needed for computer interaction, such as keyboard and pointer use, navigating through menus, and scanning. To determine the validity of these measurements, we compared data on CAP reports to a Compass report. Compass software allows an evaluator for assessment of an individual's computer input skills. Results: Results of this study showed that the CAP had high internal consistency, reliability of test-retest, concurrent validity, and convergent validity. Conclusion: Therefore, the CAP is appropriate for evaluation and determination of computer access skill of persons with physical disabilities. It is possible to get clear quantitative data on performance when providing computer access services if you can use the CAP data. Using this quantitative evidence, insights can be gained into the specific nature of any difficulties experienced by persons with physical disabilities and find wise solutions.

The glottis consists of two parts : The intermembranous portion or the anterior glottis, and the posterior glottis. The posterior glottis has been described by various inappropriate terms such as posterior commissure and interarytenoid region. The structure surrounding the posterior glottis consists of three portions ; The cartilaginous portion of the vocal fold, the lateral wall of the posterior glottis, and the posterior wall of the glottis. The posterior glottis may be a very rare site for primary squamous cell carcinoma of the larynx because of its embriologic and histologic differences from the anterior glottis. Recently we have experienced a case of a 81-year-old woman who had been presented with throat discomfort and voice change for 10months. She had the smoking history of 40 pack-year. The physical examination revealed poorly demarcated, papillary, whitish-pink colored mass on the posterior glottis. The vocal cord mobility was not affected. Biopsy under the suspension larygoscope showed moderately differentiated squamous cell carcinoma. No regional and distant metastasis was found. She was irradiated with 7000cGy over 7 weeks at a daily dose of 200cGy. No evidence of recurrence was found by the fifteenth month following radiation therapy. We report this case with a review of literature.

Student research has been proposed as an educational strategy to fulfill the current requirements in basic medical education (BME) and to compatible with the self-directed development of professionalism. It is commonly accepted that the goals of student research are to develop the competencies of critical, reflective, and self-directed thinking; problem-solving; and creativity; as well as to acquire the skills necessary to search for information and analyze the literature; to cultivate the talent of mastering a specialized field through deeply intensified learning; and to establish close relationships between students and supervisors. To successfully implement student research, authorities on BME should to plan the procedure for the student research projects and allocate personal and material resources adequately in order to provide the opportunity for self-evaluation and reflection through the completion of daily records, to develop the habit of consistently evaluating one's own study, and to maintain a collegial relationship between students and supervisors by offering the proper feedbacks in a timely and consistent manner. In conclusion, despite several obstacles and difficulties in the establishment of successful student research projects, student research could provide students the motivation to develop themselves into expert academic researchers, and play a role in educating students to help solve patients' problems based on scientific evidence in the future.

Leukemia is the most common neoplastic disease of the white blood cells which is important as a pediatric malignancy. Oral manifestations occur frequently in leukemic patients and may present as initial evidence of the disease or its relapse. The symptoms include gingival enlargement and bleeding, oral ulceration, petechia, mucosal pallor, noma, trismus and oral infections. Oral lesions arise in both acute and chronic forms of all types of leukemia. These oral manifestations either may be the result of direct infiltration of leukemic cells (primary) or secondary to underlying thrombocytopenia, neutropenia, or impaired granulocyte function. Despite the fact that leukemia has long been known to be associated with oral lesions, the available literature on this topic consists mostly of case reports, without data summarizing the main oral changes for each type of leukemia. Therefore, the present review aimed at describing oral manifestations of all leukemia types and their dental management. This might be useful in early diagnosis, improving patient outcomes.

Objective: To evaluate the relationship between allium vegetable intake and risk of prostate cancer. Methods: A systematic literature search up to May 2013 was carried out in PubMed, EMBASE, Scopus, Web of Science, Cochrane register, and Chinese National Knowledge Infrastructure (CNKI) databases, and the references of retrieved articles were also screened. The summary relative risks with 95% confidence interval for the highest versus the lowest intake of allium vegetables were calculated. Heterogeneity and publication bias were also evaluated. Results: A total of nine epidemiological studies consisting of six case-control and three prospective cohort studies were included. We found a significantly decreased risk of prostate cancer for intake of allium vegetables (OR=0.82, 95% CI 0.70, 0.97). Moreover, in the subgroup analysis stratified by allium vegetable types, significant associations were observed for garlic (OR=0.77, 95% CI 0.64-0.91) but not onions (OR=0.84, 95% CI 0.62-1.13). Conclusions: Allium vegetables, especially garlic intake, are related to decreased risk of prostate cancer. Because of the limited number of studies, further well-designed prospective studies are warranted to confirm the findings of our study.

A growing body of evidence supports lipid peroxidation as having a role in the pathogenesis of liver disease. Although the probable cause of damage to human hepatocytes may be multifactorial, free radicals have been implicated in a variety of liver diseases, particularly in the presence of iron overload and toxic substances such as ethanol. Consequently, antioxidants, particularly those of plant origin such as flavonoids, may help to reduce the risk of developing these diseases. Silybum (S.) marianum, a medicinal plant widely used in traditional European medicine for the treatment of liver disorders, was evaluated for antioxidant activity. Thin layer chromatography and High Performance Liquid Chromatography analyses of crude extract of the plant confirmed the presence of a number of flavonoids reported in the literature. The antioxidant activity of these flavonoids was measured through inhibition of lipid peroxidation and 1, 1-diphenyl-2- picrylhydrazyl radical scavenging. The crude plant extract showed marked antioxidant activity in both assays. These results suggest that S. marianum contains flavonoids with antioxidant activity, capable of inhibiting or scavenging free radicals, thus supporting its traditional use as a hepatoprotective agent.

Biobehavioral nursing research is focused on generating knowledge that examines relations among biological, behavioral, and social dimensions of health to improve outcomes. In this paper we review the findings of a biobehavioral nursing study of individuals with fibromyalgia (FM) that was framed from the perspective of an individual human response model, the FM literature, and our previous studies in midlife women. We were particularly interested in the studying the role of 'arousal' secondary to pain or to dysregulated hypothalamic-pituitary-adrenal (HPA) axis hormones during sleep and the impact on symptom expression. Unexpectedly, we did not find evidence of, arousal' or abnormal amounts of HPA axis hormones but we did find reduced amounts of growth hormone (GH) and prolactin (PRL) and of sleep spindle activity, a biomarker of sleep maintenance. We discuss these new findings and how our thinking was re-shaped to better understand the role that disturbed sleep plays in symptom expression in FM. It is argued that disturbed sleep maintenance mechanisms coupled with dysregulated somatotrophic-growth hormone axis and sleep-related PRL render individuals vulnerable to the development of or exacerbations of FM symptoms.

Objective : The aim of this review is to development of clinical trial protocol for against cosmetics as a treatment of dry skin condition. Methods : We searched the literature from 2002 through April 2012 using 5 databases. We included randomized controlled trials(RCTs) in which human participants with dry skin condition as chief complaint were treated with cosmetics. The methodological quality of all RCTs was using the Jadad score. Results : Nine RCTs met the inclusion criteria. Cosmetic types included cream (7 trials), lotion (1 trial), oil (1 trial) and body wash (1 trial). The methodological quality of the trials was generally low (Jadad score: mean 1.78; range, 1 to 3). Conclusions : The evidence for cosmetics as an effective treatment for dry skin condition(xerosis) is currently scarce and of poor quality, and is therefore inconclusive. More rigorous studies are warranted.

We report a case of a patient with lung cancer, which invaded the left atrium and pericardium. Right middle and lower lobectomy was performed with the use of the extracorporeal circulation. Postoperative pathologic examination revealed the stage of IIIB (T4N1MO). Although the postoperative clinical course was complicated by acute localized right sided pulmonary edema and the bronchopleural fistula, the patient recovered smoothly after the procedure of omentopexy with pedicled graft of greater omentum in closing the BPF. As of August 2003, he has been followed up for 6 years and he is healthy without any evidence of recurrence. We could not find any report concerning lung cancer resection using cardiopulmonary bypass in Korean literature and believe this is the first report, especially with long-term survival.
