Objective: To study the incidence, types and distribution pattern of malignant tumors in renal transplant recipients at a single center in Pakistan. Materials and methods: This retrospective study was conducted at Sindh Institute of Urology and Transplantation (SIUT) and included all transplant patients on regular follow-up from November 1986 to December 2008. The original biopsy reports and case files of all patients who developed posttransplant malignancies were reviewed and relevant demographic, clinical, radiological, and histopathological data were retrieved and analyzed. SPSS version 10.0 was used for statistical analysis. Results: Over 22 years of study period, 1816 renal transplants were carried out at our center. Among these, 44 patients developed malignancies constituting an overall incidence rate of 2.4%. All patients in this study were males with a mean age of $34.9{\pm}9.5$ years (range: 9 to 60 years). The most common type of malignancy was lymphoma (27 patients, 61.4%), followed by Kaposi's sarcoma (11 patients, 25%) and skin malignancies (3 patients, 6.8%). One case each of adenocarcinoma of the gallbladder, acute myeloid leukemia (AML), conjunctival carcinoma-in-situ and seminoma were also diagnosed. Conclusion: Posttransplant malignancies occurring in our renal transplant recipients show different incidence rates and patterns as compared with western studies.

Background: The role of totally implantable central venous port (TICVP) system is increasing. Implantation performed by radiologist with ultrasound-guided access of vein and fluoroscope-guided positioning of catheter is widely accepted nowadays. In this article, we summarized our experience of TICVP system by surgeon and present the success and complication rate of this surgical method. Materials and Methods: Between March 2009 and December 2010, 245 ports were implanted in 242 patients by surgeon. These procedures were performed with one small skin incision and subcutaneous puncture of subclavian vein. Patient's profiles, indications of port system, early and delayed complications, and implanted period were evaluated. Results: There were 82 men and 160 women with mean age of 55.74. Port system was implanted on right chest in 203, and left chest in 42 patients. There was no intraoperative complication. Early complications occurred in 11 patients (4.49%) including malposition of catheter tip in 6, malfunction of catheter in 3, and port site infection in 2. Late complication occurred in 12 patients (4.90%). Conclusion: Surgical insertion of TICVP system with percutaneous subclavian venous access is safe procedures with lower complications. Careful insertion of system and skilled management would decrease complication incidence.

Objective: To explore clinical experience and propose new ideas for treating children diagnosed with orbital rhabdomyosarcoma (RMS). Methods: We retrospectively analyzed the clinical data for30 patients (16 males and 14 females, with a median age of 6.2 years) with primary orbital RMS who were enrolled in the Department of Eye Oncology and Pediatrics of our hospital from November 2004 to December 2012. International Rhabdomyosarcoma Organization Staging Standards indicated that among the 30 patients, 4 cases were in phase II, 20 were in phase III, and 6 were in phase IV. All patients underwent a multidisciplinary collaborative model of comprehensive treatment (surgery, chemotherapy, external radiotherapy, $^{125}I$ radioactive particle implantation, and autologous peripheral blood stem-cell transplantation). Results: Follow-up was conducted until March 2013, with a median follow-up time of 47.2 months (5 to 95 months), and 7 deaths occurred. The 2-year estimated survival rate reached 86.1%, the ${\geq}3$-year estimated survival rate was 77%, and the 5-year estimated survival rate was 70.6%. Conclusions: The multidisciplinary collaborative model can be a safe and effective approach to the comprehensive treatment of children with orbital RMS. It has clinical significance in improving the tumor remission rate.

Functional gastrointestinal disorders (FGIDs) are common worldwide and cover a wide range of disorders attributable to the gastrointestinal tract that cannot be explained by structural or biochemical abnormalities. The diagnosis of these disorders relies on the symptom-based Rome criteria. In 2016 the Rome criteria were revised for infants/toddlers and for children and adolescents. In this review, we discuss the novel Rome IV criteria for infants and toddlers. The criteria for infant colic were drastically changed, whereas only minor changes were made for regurgitation, cyclic vomiting syndrome, functional diarrhea, infant dyschezia and functional constipation. In addition to this, the new Rome IV discusses underlying mechanisms of pain in infants and toddlers, including the neurodevelopment of nociceptive and pain pathways, the various factors that are involved in pain experience, and methods of pain assessment in infants and toddlers is essential for the clinician who encounters functional pain in this age group. Overall, the Rome IV criteria have become more distinctive for all disorders in order to improve the process of diagnosing pediatric FGIDs.

Cancer illness representations and screening history among residents of Kolkata, India, were investigated along with socio-demographic characteristics in an effort to understand possible motivations for health behavior. A total of 106 participants were recruited from community locations in Kolkata, India and completed surveys including demographics, the illness perception questionnaire-revised (IPQ-R), and previous experience with cancer and screening practices. Participants were 51.5% college educated, 57% female, 51.5% full-time employed with average age of 32.7 years (R: 18-60 years). Descriptive statistics were generated for the subscales of the IPQ-R, cancer-screening practices and cancer experience. Correlation analyses were conducted to investigate associations between cancer representations and socio-demographic variables. Univariate ANOVAs were calculated to determine gender differences in IPQ-R subscales and differences between participants who knew someone diagnosed with cancer versus those who did not. While 76% of participants knew someone with cancer, only 5% of the sample engaged in cancer screening. Participants perceived cancer as a serious illness with negative emotional valence. Younger age (r(100)=-.36, p<0.001) and male gender (F(1, 98)=5.22, p=0.01, ${\eta}_2$=0.05) were associated with better illness coherence. Males also reported greater personal control (F(1, 98)=5.34, p=0.02, ${\eta}_2$=0.05) were associated with better illness coherence. Low screening rates precluded analyses of the relationship between illness representations and cancer screening. Cancer was viewed as a threatening and uncontrollable disease among this sample of educated, middle class Kolkata residents. This view may act as a barrier to seeking cancer screening. Public awareness campaigns aimed at improving understanding of the causes, symptoms and consequences of cancer might reduce misunderstandings and fear, especially among women and older populations, who report less comprehension of cancer.

Purpose - The purpose of the research is to identify the demographic characteristics of the customers with high private label purchase intention. According to the previous research demographics such as gender, age, income, and residence type affect private label purchase intention indirectly through psychographics rather than directly. For instance, higher income group is time pressured, price-insensitive, quality-sensitive, less likely to enjoy shopping utilitarian products, and less likely to be variety-seeking. The main contribution of this research is to verify the results found in the previous empirical foreign research using scanner data and to investigate the differences of the characteristics of private label users between Korea and the foreign countries. Research design, data, and methodology - In order to empirically test the proposed hypotheses, scanner data of a Korean major super center was analyzed. Results - Empirical results show that private labels are more favored by old people over 50s, dwellers in individual house, lower income group, and frequent store visitors. Age of 30s, dwellers in the apartment of 30 pyung, higher income group, and consumers who purchased a large amount are less likely to purchase private labels. Gender turned out not to affect private label purchase. It should be noted that there is a significant multicollinearity among independent variables. Conclusions - The research findings provide managerial implication for retailers' private label strategy. In general, retailers heavily send private label coupons to the customers with high purchase volume. According to the research, however, store visit frequency is much more positively associated with private label purchase than purchase amount. The study has some limitations. The samples are only consumers with private label purchase experience. The data were drawn from one store and only 8 commodity products were used for the analysis. Also, if more demographics were available, a more complete description on the private brand users' profile could have been derived. We propose the following future research. Research using the data including consumers without private label experience, research investigating direction of causality between private label loyalty and store loyalty, and research using hedonic private label products such as TV and PC could be promising.

Infantile hepatic hemangioendothelioma (IHHE) is the most common benign vascular hepatic tumor in children. We analyzed the 17-year experience of IHHE. The medical records of 16 patients (M:F=8:8) treated at the Department of Pediatric Surgery and the Department of Pediatrics Seoul National University Children's Hospital between January 1991 and January 2008 were reviewed retrospectively. Mean age at presentation was 87 days (1 day - 551 days). Seventy five percent of patients were diagnosed with imaging study and 25 % with biopsy. Major symptoms were hepatomegaly (N=5), palpable abdominal mass (N=4) and congestive heart failure (N=3). Six patients had no symptoms. Kasabach-Merritt syndrome was combined in one patient. Nine patients (56.3 %) underwent operation and 2 patients (12.5 %) underwent only medical treatment. Clinical observation was tried on 5 patients (31.3 %) without any treatment. Operation was performed on the patient with clinical symptoms or on patients where the differentiation between begin and malignant could not be determined. Patients who had clinical symptoms but tumor was unreresectabile were treated medically. Among the 5 patients who had been observed for their clinical course, 2 patients showed complete regression and the tumors of the remaining 3 patients were regressing. Clinical symptoms, the age at presentation, the size of tumor and ${\alpha}$-FP, all had no significant statistical relationship with the time required for complete tumor regression. There was no relationship between the size change of the tumor and the change of ${\alpha}$-FP level. Only the size of tumor was related with clinical symptoms. One patient died of post-operatvie bleeding. Treatment plan was determined by the extent of the tumor and the presence of clinical symptoms. Observation was enough for the patients without clinical symptoms and complete resection was curative for patients with clinical symptoms. Medical treatment is an alternative for the patient whose tumor is unresectable.

This study presented the direction of cultural welfare based on ICT. For this purpose, it examined the direction of government policies and the status of cultural welfare services and it analyzed art galleries and museums focusing on experiences of cultural welfare services in a home and abroad. As a result, the museum has many changes depending on the media environment, unlike art gallery. In the age of media 1.0, the audience has experienced in real museums. As time goes by, in the age of media 2.0, the customer has opportunity to experience in virtual museums. It seems that there are many differences factor of a media environment, target (exhibits), accessibility, consumption and information. Finally, this study suggested the environmental change factors of Korean ICT cultural welfare service through this. In the future, it will be necessary to continue research on the possibility of expanding cultural welfare services for cultural enjoyment to the underprivileged.

Objectives: This study aimed to compare the level of depression and the factors affecting depression among marriage immigrant women and Korean married women living in A town. Methods: The study subjects were women living in A town. Marriage immigrant women were purposively sampled subjects who visited the Multicultural Family Support Center and conducted 1:1 face-to-face interviews. Korean married women were randomly sampled and conducted an online survey due to COVID 19. The final analysis subjects were 115 marriage immigrant women and 186 Korean married women. Data were analyzed by descriptive analysis, mean comparison(t-test, ANOVA), correlation anaylsis(Pearson's correlation coefficient) and multiple regression using SPSS 27.0. As a result of comparing the depression levels measured using the CES-D, there was no significant difference in the depression levels between the two groups of marriage immigrant women and Korean married women Results: The significant influencing factors on depression of marriage immigrant women were age(p<.01), religious status(p<.01), period of residence in Korea(p<.1), husband's job (p<.05), subjective health status(p<.1), experience of domestic violence(p<.01), and family relationships(p<.05) and the significant influencing factors on depression of Korean married women were subjective health status(p<.01), age difference with husband(p<.05), experience of domestic violence(p<.05), and family relationship (p<.001). Conclusions: Based on the results of this study, a program for mental health promotion was proposed for marriage immigrant women and Korean married women in community.
