PURPOSE: This study was conducted among 235 children aged 3 up to 11 yrs to examine the relationship between subjects' eating behaviors and obesity. METHODS: The subjects were divided into three age groups: preschoolers aged 3 to 5 yrs, early elementary school students aged 6 to 8 yrs, and late elementary school students aged 9 to 11 yrs. As a tool for eating behaviors, the recently developed nutrition quotient (NQ) questionnaire was utilized. By age group, scores were gathered and calculated in the five factors, “Balance”, “Diversity”, “Moderation”, “Regularity”, and “Practice”, which make up the NQ scores. RESULTS: The NQ scores among those aged 3 to 5, 6 to 8, and 9 to 11 yrs did not exhibit any significant differences. Among the scores for the five factors of the NQ, the Diversity scores of those aged 9 to 11 yrs were significantly higher than the scores of those aged 3 to 5 and those aged 6 to 8 yrs. The scores of those aged 3 to 5 and those aged 6 to 8 yrs were higher than the scores of those aged 9 to 11 yrs in Moderation and Regularity. When the subjects were divided into low-weight/normal and overweight/obese groups, among those aged 6 to 8 yrs, the NQ scores, Moderation, Regularity, and Practice scores were higher in the overweight/obese group than those in the low-weight/normal group. Among those aged 9 to 11 yrs, the overweight/obese group scored higher than the low-weight/normal group only in the Moderation component. CONCLUSION: From the results, to prevent obesity in elementary school students, it is practical to focus on training related to eating behavior items included in the Moderation component. Furthermore, personalized instructions on eating behaviors and nutritional education based on age are necessary to prevent obesity in children.

PURPOSE: Isolated noncompaction of the ventricular myocardium(INVM) can present as heart failure or arrhythmias in a child. It is a rare disorder, characterized by prominent trabecular meshwork and deep intertrabecular recesses. We still know little about the diagnosis, symptoms, and clinical outcomes of INVM. METHODS: We included in our study 6 patients who showed ventricular noncompaction on echocardiography. Patients were diagnosed as INVM were excessively prominent trabeculations with deep intertrabecular recesses were found on echocardiography. Patients who had other complex heart lesions such as pulmonary atresia with intact ventricular septum in addition to ventricular noncompaction, were excluded. RESULTS: Age at presentation ranged from 1 day 7 years, with follow up being as long as 6 years. Symptoms at initial presentation were heart murmur, paroxysmal supraventricular tachycardia, cyanosis, feeding intolerance, ventricular tachycardia, and cardiomegaly at fetal screening. Prominent trabeculations and intertrabecular recesses were observed at left ventricular apex in all six patients. All patients were alive at last follow-up. One patient showed WPW syndrome on electrocardiography. Echocardiography revealed decreased systolic function in 4 patients, and decreased systolic and diastolic function in 1 patient. One patient is currently asymptomatic. CONCLUSION: Six patients were diagnosed with INVM with various symptoms at initial presentation. Echocardiography is the most important tool in the diagnosis of INVM due to its morphological characteristics. INVM can rarely be the cause of long term systolic dysfunction, and early detection by echocardiographic screening may be beneficial.

PURPOSE: Clinicopathological features were investigated to clarify the outcome and prognostic indicators for patients with IgA nephropathy in Korean children. METHODS: We reviewed the outcomes of 61 patients in whom IgA nephropathy was diagnosed before the age of 15 years from 1991 to 2005 and followed-up at least for one year. All patients were confirmed by renal biopsy. RESULTS: After mean follow-up of 5.2 years from onset, 24 patients of 61 (39.3%) were in clinical remission at the last examination. Thirty patients (49.2%) had hematuria or mild proteinuria (<1 g/ m2/d), five (8.2%) had severe proteinuria (> or =1 g/m2/d), and two (3.3%) had chronic renal failure. By univariate analysis, initial presentation at onset and Haas classification were less concordant with outcome. Hypertension during follow-up, rather than hypertension at presentation, was significantly correlated with outcomes (P<0.01). Sixty percent of patients who had more than 20% of glomerular sclerosis or crescent progressed to severe proteinuria or chronic renal failure, as compared with 7.1% of those who did not (P<0.01). CONCLUSION: Prognosis of childhood IgA nephropathy had a relatively benign course during a mean follow-up of 5.2 years. Persistent hypertension during follow-up and more than 20% of glomerular sclerosis or crescent were strong predictors of a progressive course of IgA nephropathy. A new histologic classification according to characteristics of childhood IgA nephropathy must be established to assess prognosis. Further efforts should be made to understand the prognosis of IgA nephropathy through long-term follow-up.

Colonic necrosis is known as a rare complication following the administration of Kayexalate (sodium polystryrene sulfonate) in sorbitol. We report a rare case of colonic mucosal necrosis following Kalimate (calcium polystryrene sulfonate), an analogue of Kayexalate without sorbitol in a 34-yr-old man. He had a history of hypertension and uremia. During the management of intracranial hemorrhage, hyperkalemia developed. Kalimate was administered orally and as an enema suspended in 20% dextrose water to treat hyperkalemia. Two days after administration of Kalimate enema, he had profuse hematochezia, and a sigmoidoscopy showed diffuse colonic mucosal necrosis in the rectum and sigmoid colon. Microscopic examination of random colonic biopsies by two consecutive sigmoidoscopies revealed angulated crystals with a characteristic crystalline mosaic pattern on the ulcerated mucosa, which were consistent with Kayexalate crystals. Hematochezia subsided with conservative treatment after a discontinuance of Kalimate administration.

PURPOSE: The purpose of this study is to understand nursing college life experiences of North Korean Defectors and identify their meanings. METHODS: The study collected data through individual in-depth interviews among six undergraduates or graduates from nursing colleges, using phenomenological research methodology of Colaizzi-one of qualitative research approaches. RESULTS: Six categories drawn as a result of research include ‘Be bumped against hard reality wall’, ‘Bondage of discrimination and prejudice’, ‘Endure and stand with strength of faith’, ‘Myself grown up along with work’, ‘Becoming one amid differences’, and ‘Stepping towards unification’. CONCLUSION: The result of this study would contribute to understanding academic and interpersonal difficulties North Korean defectors might experience at nursing colleges. And it may also help people to learn that they would play an important role in integration of the nursing fields of South and North Korea as well as the nation's unification. Along the way, the results of the study could be basic data to establish national policy helping North Korean defectors adapt to nursing college life, and develop the supporting system of colleges as well as setting up appropriate supports and measures from the perspective of the nursing field.

Churg-Strauss syndrome is characterized by asthma, peripheral and tissue eosinophilia, extravascular granuloma formation, and vasculitis of multiple organ systems. The gastrointestinal tract may be involved in 20% to 50% of patients, mainly with abdominal pain, diarrhea and GI bleeding. Ulcers in the small and large bowel are an uncommon manifestation, usually detected during laparotomy performed in the setting of bowel perforation. Endoscopically proven segmental colonic aphthous ulcers with typical pathologic findings such as extravascular granuloma formation, eosinophilic infiltration, or vasculitis are a rarer manifestation. We present a patient with Churg-Strauss syndrome and two aphthous ulcers in the sigmoid colon that healed after treatment with high dose steroids and cyclophosphamide.

Dendritic cells (DCs), which are regarded as the most potent antigen-presenting cells, are involved in innate and adaptive immunity. Upon uptake of pathogens, DCs express cell surface markers and secrete cytokines. In this study, we analyzed production of cytokines and found that interleukin (IL)-10 and transforming growth factor (TGF)-beta production significantly increased in bone marrow-derived DCs and a mouse DC line, DC2.4, after treatment with crude antigen (CA) from liver fluke, Clonorchis sinensis. However, expression patterns of several activation molecules did not change. In addition, following treatment of DC2.4 cells with antigen from the lung fluke, Paragonimus westermani, production of IL-10 and TGF-beta significantly increased compared with groups treated with other parasite antigens, Spirometra erinacei plerocercoid CA and Echinococcus granulosus hydatid cystic fluid. We also found that treatment of DC2.4 cells with C. sinensis CA resulted in rapid and significant phosphorylation of extracellular signal-regulated kinase 1/2, a mitogen-activated protein kinase. Following treatment of DC2.4 cells with C. sinensis CA, treatment with an inhibitor specific to an extracellular signal-regulated kinase inhibited production of IL-10 and TGF-beta. Our results suggest that CA from C. sinensis has a role in the anti-inflammatory function of DC cells by inducing IL-10 and TGF-beta through activation of extracellular signal-regulated kinase 1/2.

Autoimmune hepatitis (AIH), primary sclerosing cholangitis (PSC), and primary biliary cirrhosis (PBC) are the major immune-mediated chronic liver diseases. They are characterized by circulating autoantibodies, hypergammaglobulinemia, unique clinical features, and associations with other autoimmune diseases, such as inflammatory bowel disease and autoimmune thyroiditis. Primary biliary cirrhosis is known to be associated with inflammatory bowel disease, such as ulcerative colitis. On the other hand, autoimmune hepatitis is rarely associated with ulcerative colitis. Here, we report a case diagnosed as autoimmune hepatitis combined with ulcerative colitis on the basis of histological and endoscopic findings.

Ulcerative colitis is an idiopathic chronic inflammatory bowel disease that exclusively involves the colon. It is characterized by diffuse mucosal inflammation and a recurrent course of remission and relapse. Factors such as smoking, diet, genetic factors and miocrobial infection have all been suggested as causes of ulcerative colitis. One of the important issues in the treatment of ulcerative colitis is opportunistic infection associated with the usage of corticosteroid and immunosuppresant. In most cases, opportunistic cytomegalovirus infection after treatment with corticosteroid or immunosuppressant worsens the course of ulcerative colitis. However, cytomegalovirus infection is uncommon in immunocompetent patients and it is rare in immunocompetent patients with corticosteroid naive ulcerative colitis. We report here on a case in which an immunocompetent patient was newly diagnosed with ulcerative colitis and cytomegalovirus coinfection simultaneously.

PURPOSE: To evaluate the clinical impact of the altered expression of cell cycle regulators in stage I and II breast cancers. MATERIALS AND METHODS: The interaction between cyclin D1/E and p27Kip1 expressions were analyzed using tissue microarray (TMA) technology in 133 breast cancers. Data from the immunohistochemical assays of 3 molecules were merged, and analyzed, with a Ki67 labeling index of the same tumors. RESULTS: Cyclin D1 was expressed in 72 breast carcinomas (54.1%) and cyclin E in 60 (45.1%) out of the 133 breast carcinomas. Expressions of cyclin D1 and cyclin E were inversely related to each other, and significantly associated with the estrogen receptor (ER) expression and differentiation of the breast carcinoma. The expression of cyclin E was significantly decreased in tumors expressing cyclin D1 (p=0.022). There was a trend for cyclin D1 expression to increase in tumors expressing p27Kip1 (p=0.053), but the expression of cyclin E did not correlate with p27Kip1 expression. The Ki67 labeling index was markedly increased in tumors expressing cyclin E, whereas it was significantly decreased in the cyclin D1 or p27Kip1 expressing-tumors. From survival analysis, cyclin E expression was the only significant variable for the prediction of poor survival. CONCLUSION: The abnormal expressions of cell cycle regulatory molecules are prevalent, and interrelated with each other in breast cancer. Integration of TMA technology allowed a high-throughput analysis for correlating molecular the in situ findings, with the clinico-pathologic information. Among the three molecules studied, the cyclin E had a prognostic implication for stage I and II breast cancer.
