Background: Helicobacter pylori (H. pylori) is the most common chronic infectious agent in the stomach. Most importantly, it may lead to atrophy, metaplasia and cancer. The aim of this study was to investigate the incidence of H. pylori infection and to detect early mucosal changes that may lead to malignant degeneration in children. Materials and Methods: Children who underwent upper gastrointestinal endoscopy were included. Familial history of gastric cancer was noted. Endoscopic examinations were performed by a single pediatric gastroenterologist. A minimum of three biopsy samples were collected during endoscopy. The patients were accepted as H. pylori infected if results of biopsies and rapid urease test were both positive. Biopsies were evaluated for the presence and degree of chronic inflammation, the activity and severity of gastritis, glandular atrophy and intestinal metaplasia. Results: A total of 750 children (388 boys, 362 girls) were evaluated in our study, with a mean age of 10.1 years. A total of 390 patients (52%) were found to be infected with H. pylori. Among the H. pylori infected patients, 289 (74%) were diagnosed to have chronic superficial gastritis, 24 (6.2%) had gastric atrophy. Most strikingly, intestinal metaplasia was observed in 11 children, all were in the H. pylori positive group. There was no difference in the mean of age, gender and socioeconomic class between H. pylori infected and non-infected groups. The frequency of gastric cancer in family members (4 in number) was higher in patients with H. pylori infection. No gastric cancer case was reported from the parents of non-infected children. The worst biopsy parameters (atropy and metaplasia) were improved after H. pylori eradication on control endoscopy. Conclusions: The current study shows a higher prevalence of familial history of gastric cancer in H. pylori infected children. Intestinal metaplasia was also higher in the infected children. Eradication of H. pylori infection for this risk group may prevent subsequent development of gastric cancer.
Purpose : Bacteremia is one of the most common causes of morbidity and mortality in children with cancer. The aim of this study was to evaluate the clinical features of bacteremia in pediatric cancer patients. Methods : We retrospectively analyzed bacteremia episodes occurred in pediatric cancer patients at Samsung Medical Center from January 2008 to December 2010. We excluded bacteremia episodes after hematopoietic stem cell transplantation. Results : A total of 141 blood cultures were positive in 121 patients. Thirteen cultures due to contamination were excluded. For analysis, 128 bacteremia episodes in 108 children were included. Gram-positive organisms accounted for 46.9% (60/ 128) and gram-negative organisms for 53.1% (68/128). The source of bacteremia was identified in 21.1% of episodes. Bacteremia due to catheter related infection was observed in 9.4% of episodes (12/128 episodes) and gram-positive organisms were isolated in 75% of episodes (9/12). There were 10 cases (7.8%) of bacteremia associated with septic shock and gramnegative organisms were isolated in 80% of episodes (8/10). Relapses were documented within 30 days in 2 patients who cleared bacteremia which was confirmed after negative blood cultures. Mortality associated with bacteremia was not observed. Conclusion : Continuous monitoring is needed to maintain the tailored strategies to manage pediatric cancer patients with neutropenic fever who are at high risk of developing bacteremia in each institution.
Objective: The aim of this study was to investigate the meaning of "positive attitude" for medical surgical nurses in caring for cancer patients. Methods: A qualitative method was used in this qualitative descriptive study with data from nurses who had volunteered to participate in an in-depth interview that was conducted between January and February 2012. A total of 10 nurses in general medical and surgical wards of a district hospital were interviewed. Results: The study used three broad themes to describe this multifaceted construct: showing empathy, seeing positively and behaving positively. The nurses were aware of their attitudes towards being positive with cancer patients and its significance in support for cancer patients. Conclusions: The findings of this study can serve as a platform upon which educational and other support programmes can be developed in order to meet the needs of those general nurses working with cancer patients. Future studies are recommended to examine nurses' beliefs about cancer that are thought to affect positive attitudes toward cancer patients.
Purpose: Acute internal hemorrhage is an occasionally life-threatening complication in pediatric cancer patients. Many therapeutic approaches have been used to control bleeding with various degrees of success. In this study, we evaluated the efficacy of selective internal iliac artery embolization for controlling acute intractable bleeding in children with malignancies. Methods: We retrospectively evaluated the cases of 6 children with various malignancies (acute lymphoblastic leukemia, acute myelogenous leukemia, chronic myelogenous leukemia, T-cell prolymphocytic leukemia, Langerhans cell histiocytosis, and rhabdomyosarcoma), who had undergone selective arterial embolization (SAE) of the internal iliac artery at the Chonnam National University Hwasun Hospital between January 2004 and December 2009. SAE was performed by an interventional radiologist using Gelfoam$^{(R)}$ and/or Tornado$^{(R)}$ coils. Results: The patients were 5 boys and 1 girl with median age of 6.9 years (range, 0.7-14.8 years) at the time of SAE. SAE was performed once in 4 patients and twice in 2, and the procedure was unilateral in 2 and bilateral in 4. The causes of hemorrhage were as follows: hemorrhagic cystitis (HC) in 3 patients, procedure-related internal iliac artery injuries in 2 patients, and tumor rupture in 1 patient. Initial attempt at conservative management was unsuccessful. Of the 6 patients, 5 (83.3%) showed improvement after SAE without complications. Conclusion: SAE may be a safe and effective procedure for controlling acute intractable hemorrhage in pediatric malignancy patients. This procedure may obviate the need for surgery, which carries an attendant risk of morbidity and mortality in cancer patients with critical conditions.
Purpose: Malnutrition is a significant issue for pediatric patients with cancer. We sought to evaluate the effectiveness and complication rate of percutaneous endoscopic gastrostomy (PEG) placement in pediatric oncology patients. Methods: A retrospective chart review was performed on 49 pediatric oncology patients undergoing PEG placement at Johns Hopkins All Children's Hospital between 2000 and 2016. Demographic and clinical characteristics, complications, absolute neutrophil count at time of PEG placement and at time of complications, length of stay, and mortality were identified. Weight-for-age Z-scores were evaluated at time of- and six months post-PEG placement. Results: The overall mean weight-for-age Z-score improved by 0.73 (p<0.0001) from pre- (-1.11) to post- (-0.38) PEG placement. Improvement in Z-score was seen in patients who were malnourished at time of PEG placement (1.14, p<0.0001), but not in those who were not malnourished (0.32, p=0.197). Site infections were seen in 12 (24%), buried bumper syndrome in five (10%), and tube dislodgement in one (2%) patient. One patient (2%) with fever was treated for possible peritonitis. There were no cases of other major complications, including gastric perforation, gastrocolic fistula, clinically significant bleeding, or PEG-related death documented. Conclusion: Consistent with previous studies, our data suggests a relationship between site complications (superficial wound infection, buried bumper syndrome) and neutropenia. Additionally, PEG placement appears to be an effective modality for improving nutritional status in malnourished pediatric oncology patients. However, larger prospective studies with appropriate controls and adjustment for potential confounders are warranted to confirm these findings.

Background: Complementary alternative medicine (CAM) use in children with cancer is widespread. Health-care providers (HCP) need to acknowledge and address this need. This study explored and compared perspectives on CAM of HCP and parents of young patients with cancer in Indonesia. Materials and Methods: We conducted a cross-sectional study using semi-structured questionnaires in HCP and parents of childhood cancer patients at an Indonesian academic hospital. Results: A total of 351 respondents participated: 175 HCP (response rate 80%) and 176 parents (response rate 80%). Parents were more likely than HCP to think that chemotherapy can cure cancer (80% compared to 69%, P=0.013). Nearly half of all parents (46%) and HCP (45%) doubted whether CAM can cure cancer. Parents were more likely than HCP to think that CAM can be helpful in childhood cancer treatment (54% compared to 35%, P=0.003). The most recommended CAM by HCP was self-prayer (93%). Reasons for recommending CAM were: hope for improvement of the child's condition (48%), patient wants to stop treatment (42%). Most discouraged CAM by HCP was by old-smart people (70%), the reasons being: lack of evidence for usefulness (77%), lack of CAM knowledge (75%). The proportion thinking that patients were unlikely to raise the CAM topic if they perceived that doctors were skeptical was higher in parents than in HCP (52% versus 1%) (P<0.001). Most HCP (71%) and parents (77%) acknowledged that their knowledge about safety and efficacy of CAM was inadequate (P=ns). The proportion that wanted to learn or read more about CAM was higher among parents than HCP (48% compared to 31%, P=0.002). Conclusions: HCP and parents have different perspectives on CAM use in children with cancer. HCP should enhance their CAM knowledge and encourage open communication about CAM with parents. If doctors' skepticism is perceived, parents are unlikely to raise CAM as a topic.
We conducted a comprehensive study to investigate the role of genes involved in transport pathways in response to chemotherapy and clinical outcome of osteosarcoma cases. Genotyping of six SNPs was performed in a 384-well plate format on the Sequenom MassARRAY platform for 208 osteosarcoma patients to reveal any correlations of the six SNPs with response to chemotherapy and clinical outcome. Individuals with the ABCB1 rs1128503 TT and ABCC3 rs4148416 TT genotypes had a higher probability of responding poorly to chemotherapy, indicated by odds ratios (ORs) of 2.46 (95%CI, 1.21-5.74) and 3.78 (95% CI, 1.20-13.85), respectively. Moreover, the ABCB1 rs1128503 TT and ABCC3 rs4148416 TT genotypes were significantly associated with shorter diseasefree survival (DFS) and overall survival (OS). Our study found the two SNPs in two transporter genes and one phase II metabolism enzyme to be associated with response to chemotherapy and overall survival in osteosarcoma patients, suggesting potential prognostic biomarker applications of the two SNPs.
The purpose of this study were to identify the quality of life for the mothers of hospitalized chronic pediatric patients, and to explore the factors affecting the QOL of those mothers. The subjects were 201 mothers whose children had hospitalized at one University hospital with chronic diseases. Data were collected from the December, 1997 to December, 1998. We used a revised QOL instrument consisting of 34 items, 5 point likert scale based on the Noh's QOL instrument. The revised QOL consists of six subscales, those are physical status and function, self esteem, emotional status, economic status, relationship with family members, and relationship with neighborhood. Data were analyzed by t-test, ANOVA, Pearson's correlation using SPSS-PC. The results were as follows: 1. The mean score of quality of life for the mothers of chronic pediatric patients was 100.31, and item mean was 2.95. In subscale analysis, item mean of economic status was the lowest, and that of relationship with family members was the highest. 2. Correlations between characteristics of chronic pediatric patients, their mothers and QOL of mothers were as follows; 1) Total QOL of mothers had a significant positive relationship with progressing time relapse after diagnosing and age of mothers. There was a significant negative relationship between the total QOL of mothers and number of hospitalization of their children. 2) QOL on self esteem and economic status had a significant relationship with age of pediatric patients, the time relapse after diagnosis, and age of mothers. Total number of family members and QOL on economic status showed a significant positive relationship. QOL on emotional status, economic status, and relationship with family members of mothers showed negative correlations with the number of hospitalization of their children. 3. Followings were the result of difference in QOL among different demographic cha- racteristics of the subjects. 1) QOL on economic status of mothers was significantly higher when fathers of pediatric patients had jobs. 2) Total QOL score, QOL on emotional status, and QOL on relationship with neighborhood were significantly higher when mothers of pediatric patients had spouses. 3) QOL on self esteem of mothers was significantly higher when mothers had religion. 4. Followings were the result of difference in QOL among different diagnosis of the children. 1) Total QOL score of mothers whose children had congenital heart disease was higher than that of mothers whose children had leukemia and cancer. 2) QOL on emotional status, economic status, and relationship with family members of mothers whose children had congenital heart disease were higher than those of mothers whose children had leukemia, cancer, and epilepsy.
Colorectal cancer (CRC) is a third leading cause of cancer-related death in cancer patients. Sporadic and inflammation-related colon carcinogenesis are major mechanism of colorectal cancer. In vivo CRC models have been developed and implicated to understand their mechanisms upon a different type of CRC. Moreover, recently animal models have played important roles in chemopreventive and preclinical trials over the years. In this mini-review, the aim is to introduce various animal models of CRC and help the understanding to establish in vivo experimental plans according to the cancer type of CRC.

Pediatric infection with Helicobacter pylori may occur early in childhood and persist lifelong. Global pediatric clinical studies have reported a decreasing tendency in the overall rate of H. pylori eradication. In pediatric patients with H. pylori infection, pediatric patients with peptic ulcer, and the first-degree relatives of patients with a history of gastric cancer, it is commonly recommended that H. pylori strains be eradicated. Antibiotic drug resistance to H. pylori, which has been reported to vary widely between geographic regions, is mainly associated with treatment failure in these patients. It is therefore imperative that the antibiotic resistance rates of H. pylori in children and adolescents be meticulously monitored across countries and throughout geographic regions. This paper particularly focuses on the antibiotic drug resistance of H. pylori and the thearpy of pediatric H. pylori infection cases.
