The objectives of this study were to identify the phenomena of school health nursing at schools in Korea and to contribute to building a school health domain of International Classification for Nursing Practice. A retrospective method was used in this study to develop ICNP during the period from July to October 200l. The procedure of the study involved choosing nursing phenomena using preliminary terms from the reports on the field of school health nursing practice documented by nursing students in 10 different nursing colleges. The detail procedures of the study were as follows. 1) Choosing nursing phenomena by using preliminary terms 2) Choosing the characteristics of school health nursing practice from the selected nursing phenomena 3) In order to make a consensus regarding the appropriate characteristics of phenomena. 15 study group members re-categorized the nursing phenomena through 5 times of cyber meetings and 3 times of formal meetings. 4) To verify each characteristic, 5 community nursing faculties and 25 school health nurses participated in the procedure to give scores on nursing characteristics. 5) Classification of the definite nursing phenomena and characteristics. Following the 5 step procedures, school health nursing phenomena were categorized into human and environmental domains. Human domains were classified into human behavioral and functional domains. Environmental domains were classified into physical and psychosocial domains. The essential characteristics of each phenomena were selected when it obtains the mean score of 3.0 or over at the related characteristics. The human behavioral domain consisted of 7 phenomena including risk for spinal disorder, inadequate dietary habit, inadequate weight control, smoking and substance abuse, inadequate stress management, inadequate sex related coping strategies and inadequate accident management. The human functional domain consisted of 6 phenomena including inadequate eye care and visual management, risk for respiratory disorder, inadequate dental health care, inappropriate infectious disease control, risk for gastrointestinal disorder, and lack of sexual identity. The physical environmental domain consisted of 6 phenomena including risk for incident at inside classroom, risk for incident at outside classroom, risk for incident around school, risk for exposure to hazardous facilities around school. inadequate garbage and disposal management, and inadequate physical environment for learning. The psychosocial domain included impaired social interaction at school. Each phenomenon was composed of 2 to 8 characteristics and all phenomena will include a total number of 85 characteristics. The phenomena of school health nursing in Korea partially confirmed school health architecture of ICNP. Further study on verification of school health nursing phenomena in Korea needs to be done to support the findings of this study through review of literature on nursing classifications or field studies.

Purpose: To evaluate the clinical spectrum of posttransplantation lymphoproliferative disorder (PTLD) after solid organ transplantation (SOT) in children. Methods: We retrospectively reviewed the medical records of 18 patients with PTLD who underwent liver (LT) or kidney transplantation (KT) between January 1995 and December 2014 in Seoul National University Children's Hospital. Results: Eighteen patients (3.9% of pediatric SOTs; LT:KT, 11:7; male to female, 9:9) were diagnosed as having PTLD over the last 2 decades (4.8% for LT and 2.9% for KT). PTLD usually presented with fever or gastrointestinal symptoms in a median period of 7 months after SOT. Eight cases had malignant lesions, and all the patients except one had evidence of Epstein-Barr virus (EBV) involvement, assessed by using in situ hybridization of tumor tissue or EBV viral load quantitation of blood. Remission was achieved in all patients with reduction of immunosuppression and/or rituximab therapy or chemotherapy, although 1 patient had allograft kidney loss and another died from complications of chemotherapy. The first case of PTLD was encountered after the introduction of tacrolimus for pediatric SOT in 2003. The recent increase in PTLD incidence in KT coincided with modification of clinical practice since 2012 to increase the tacrolimus trough level. Conclusion: While the outcome was favorable in that all patients achieved complete remission, some patients still had allograft loss or mortality. To prevent PTLD and improve its outcome, monitoring for EBV infection is essential, which would lead to appropriate modification of immunosuppression and enhanced surveillance for PTLD.

This study was conducted in July-August, 1984, to define the causes of chronic gastrointestinal symptoms in rural population and to provide data for the management of such patients. A household survey was conducted to identify all the residents of Youngchun and Sungiu counties in Kyungpook province who were over 20 years of age, had chronic upper gastrointestinal symptoms for over the last 6 months, never had medical examination for the symptoms, and volunteered to participate in the gastroscopic examination. Gastroscopy was done for 106 males and 108 females. Gastric ulcer was found in 16.8% of all the examinees, duodenal ulcer in 15.4%, gastritis in 14.0%, and gastric cancer in 3.7%. No lesion was found by gastroscopy in 52.3%. Gastric ulcer more common in male(26.4%) than in female(7.4%) (p<0.01) and the same was true for duodenal ulcer(20.8% of male, 10.2% of female). Gastric cancer was found in 7.5% of the male while none of the female had gastric cancer. A higher proportion of the female (68.5%) showed normal finding in the gastroscopy than the male(35.9%) (p<0.01). No significant association was found between the upper gastrointestinal symptoms and the gastroscopic findings. The higher prevalence rate of gastric ulcer than that of duodenal ulcer in this study which is the reverse of the study findings of urban area in Korea and western countries may be related in part with the dietary habit and social environment of the rural population. Although early diagnosis is the most important for the treatment of gastric cancer, many of the people with chronic upper gastrointestinal complaints defer the diagnosis and treatment. It is may be due to lack of the knowledge of diseases and the health care attitude of the rural people. A national program for the health education and mass screening for the gastric cancer should be developed.

Objectives : The aim of this study was to compare psychosocial characteristics of the functional gastrointestinal disorders FGID group, non-FGID group, and control group and determine factors affecting the QOL of patients with FGID. Methods : 135 patients diagnosed with FGID were selected. 79 adults had no observable symptoms of FGID (control group) and 88 adults showed symptoms of FGID (non-FGID group). Demographic factors were investigated. The Korean-Beck Depression Inventory-II, Korean-Beck Anxiety Inventory, Korean-Childhood Trauma Questionnaire, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale, Patient Health Questionnaire-15 and WHO Quality of Life Assessment Instrument Brief Form were used to assess psychosocial factors. A one-way ANOVA was used to compare differences among groups. Pearson correlation test was performed to analyze the correlation of psychosocial factors and QOL of the FGID group. Further, a hierarchical regression analysis was conducted to determine factors affecting the QOL of the FGID group. Results : Between-group differences were not significant in demographic characteristics. Depression (F=48.75, p<0.001), anxiety (F=14.48, p<0.001), somatization (F=24.42, p<0.001) and childhood trauma (F=12.71, p<0.001) were significantly higher in FGID group than in other groups. Social support (F=39.95, p<0.001) and resilience (F=17.51, p<0.001) were significantly lower in FGID group than in other groups. Resilience (β=0.373, p<0.01) was the most important explanatory variable. The explained variance was 47.2%. Conclusions : Significantly more symptoms of depression, anxiety, childhood trauma, and somatization were observed for the FGID group. This group also had less social support, resilience, and quality of life than the non-FGID and control groups. The key factor for quality of life of the FGID group was resilience.

Purpose: To analyze the clinical spectrum of posttransplantation lymphoproliferative disorder (PTLD) after liver transplantation in children. Methods: From January 1988 to June 2009, we retrospectively reviewed the medical records of 8 PTLD cases among 148 pediatric patients underwent liver transplantation. The age at transplantation, time of presentation after transplantation, clinical manifestations, histologic diagnosis, results of EBV (Epstein-Barr virus) assessments, managements and outcomes of PTLD were investigated. Results: The prevalence of PTLD in liver transplant pediatric recipients was 5.4% (8 of 148). The mean age of patients was 25.4${\pm}$21.3 months (range 10 to 67 months). Seven of 8 patients (87.5%) underwent liver transplantation before 1 year of age. The common clinical presentations were persistent fever (8 of 8, 100%) and bloody diarrhea (6 of 8, 75%). PTLD was diagnosed with gastrointestinal endoscopic biopsies in five patients and surgical biopsies in three. Histologic findings showed early lesion in three patients, polymorphic in two, and monomorphic in three. Burkitt lymphoma and lymphoblastic lymphoma were found in two of 3 monomorphic patients. Seven of 8 patients were found with EBV-positive. Eight patients were treated with dose reduction of immunosuppressants and infusion of ganciclovir. Rituximab was added to four patients. PTLD were successfully managed in all patients except one who died of sepsis during chemotherapy. Conclusion: Major risk factor of PTLD was to undergo liver transplantation before 1 year of age. Continuous monitoring for EBV viral load and gastrointestinal endoscopic biopsy may be useful to early detection of PTLD.

Objectives : Stress induces alteration of gastrointestinal function in which interleukin (IL) and hypothalamo-pituitary-axis are involved. Depression again is associated with functional gastrointestinal disorders (FGID) and interleukins. The author attempted to look into the role of interleukins in the FGID also the association of depression and stress in this context. Methods : Entered were 20 patients with FGID, diagnosed by Rome IT criteria and 20 healthy controls. Depression was measured by Hamilton Rating Scale for Depression (HAM-D), and stress of the last one year by Schedule of Recent Experience (SRE). Serum levels of IL-$1\beta$, IL-2, IL-6 were measured by Enzyme-linked Immunosorbent Assay and serum cortisol by Fluorescence Polarization Immunoassay. The results were as follows : Results: 1) Serum levels of IL-$1\beta$, IL-2 were significantly lower in the patients with FGID than those in the controls, but level of IL-6 did not differ between two groups. 2) The patient group showed significantly higher level of serum cortisol as well as higher degrees of depression and stress. 3) Positive correlation was noted between depression and serum cortisol, and between depression and IL-2. A trend of negative correlation was seen between depression IL-$1\beta$. Positive correlation was noted between SRE and IL-6 and IL-6 and serum cortisol. Conclusions : It was concluded that FGID might be related to depression and stress. Changes of the interleukins might be involved with elevated cortisol level.

SMAD7 has been identified as a functional candidate gene for colorectal cancer (CRC). SMAD7 protein is a known antagonist of the transforming growth factor beta ($TGF-{\beta}$) signaling pathway which is involved in tumorigenesis. Polymorphisms in SMAD7 may thus alter cancer risk. The aim of this study was to investigate the influence of a SMAD7 gene polymorphism (rs2337107) on risk of CRC and clinicopathological features in an Iranian population. In total, 210 subjects including 105 patients with colorectal cancer and 105 healthy controls were recruited in our study. All samples were genotyped by TaqMan assay via an ABI 7500 Real Time PCR System (Applied Biosystems) with DNA from peripheral blood. The polymorphism was statistically analyzed to investigate the relationship with the risk of colorectal cancer and clinicopathological properties. Logistic regression analysis revealed that there was no significant association between rs2337107and the risk of colorectal cancer. In addition, no significant association between genotypes and clinicopathological features was observed (p value>0.05). Although there was not any association between genotypes and disorder, CT was the most common genotype in this population. This genotype prevalence was also higher in the patients with well grade (54.9%) and colon (72.0%) tumors. Our results provide the first evidence that this polymorphism is not a potential contributor to the risk of colorectal cancer and clinicopathological features in an Iranian population, and suggests the need of a large-scale case-control study to validate our results.

In-utero exposure to valproic acid (VPA) has been known as a potent inducer of autism spectrum disorder (ASD), not only in humans, but also in animals. In addition to the defects in communication and social interaction as well as repetitive behaviors, ASD patients usually suffer from gastrointestinal (GI) problems. However, the exact mechanism underlying these disorders is not known. In this study, we examined the gross GI tract structure and GI motility in a VPA animal model of ASD. On embryonic day 12 (E12), 4 pregnant Sprague-Dawley (SD) rats were subcutaneously injected with VPA (400 mg/kg) in the treatment group, and with phosphate buffered saline (PBS) in the control group; the resulting male offspring were analyzed at 4 weeks of age. VPA exposure decreased the thickness of tunica mucosa and tunica muscularis in the stomach and ileum. Other regions such as duodenum, jejunum, and colon did not show a significant difference. In high-resolution microscopic observation, atrophy of the parietal and chief cells in the stomach and absorptive cells in the ileum was observed. In addition, decreased staining of the epithelial cells was observed in the hematoxylin and eosin (H&E)-stained ileum section. Furthermore, decreased motility in GI tract was also observed in rat offspring prenatally exposed to VPA. However, the mechanism underlying GI tract defects in VPA animal model as well as the association between abnormal GI structure and function with ASD is yet to be clearly understood. Nevertheless, the results from the present study suggest that this VPA ASD model undergoes abnormal changes in the GI structure and function, which in turn could provide beneficial clues pertaining to the pathophysiological relevance of GI complications and ASD phenotypes.

Background/Aims There has been major progress in our understanding of the irritable bowel syndrome (IBS), and novel treatment classes have emerged. The Rome IV guidelines were published in 2016 and together with the growing body of Asian data on IBS, we felt it is timely to update the Asian IBS Consensus. Methods Key opinion leaders from Asian countries were organized into 4 teams to review 4 themes: symptoms and epidemiology, pathophysiology, diagnosis and investigations, and lifestyle modifications and treatments. The consensus development process was carried out by using a modified Delphi method. Results Thirty-seven statements were developed. Asian data substantiate the current global viewpoint that IBS is a disorder of gut-brain interaction. Socio-cultural and environmental factors in Asia appear to influence the greater overlap between IBS and upper gastrointestinal symptoms. New classes of treatments comprising low fermentable oligo-, di-, monosacharides, and polyols diet, probiotics, non-absorbable antibiotics, and secretagogues have good evidence base for their efficacy. Conclusions Our consensus is that all patients with functional gastrointestinal disorders should be evaluated comprehensively with a view to holistic management. Physicians should be encouraged to take a positive attitude to the treatment outcomes for IBS patients.

We examined total body irradiation (TBI)-induced effects by complete blood count (CBC) and fluorescence-activated cell sorter analysis (FACS) in the piglet following radiation irritation. A CBC included red blood cell count, white blood cell count, and platelet cell count. Four piglets were examined in this study and each piglet was divided by irradiation dose, two piglets with 4 Gy, two with 6 Gy, one with 8 Gy. All piglets showed leukopenia, thrombocytopenia after irradiation. In 6 and 8 Gy group, three piglets showed severe hemostatic disorder and gastrointestinal disorder suchas diarrhea and anorexia, and they died between 10 and 15 days after radiation irritation. In 4 Gy, two piglets showed no clinical sign after radiation injury, but persistent leukopenia was shown in blood examination. We suggest that a single TBI dose less than 6 Gy is adequate for conditioning piglet for bone marrow transplantation.
