Purpose: To report a nationwide survey on neuroblastoma conducted by the Korean Association of Pediatric Surgeons (KAPS) in 2020. Methods: The clinical data of pediatric patients diagnosed with and treated for neuroblastoma from 2005 to 2019 in 19 hospitals of KAPS members were collected. Survival and prognostic factor analyses were performed using the log rank test and Cox proportional hazard analysis. A p-value <0.05 was considered significant. Results: A total of 669 patients with neuroblastoma were registered for the study. The results were presented and discussed at the 36th annual meeting of the KAPS, which was held in Seoul on August 21, 2020. Conclusion This study provides information on patient demographics, prognostic outcomes, and comprehensive treatment outcomes for neuroblastoma. The study is expected to be an important reference for improving pediatric surgeons’ understanding and treatment of neuroblastoma.

Purpose: The purpose of this study was to examine the effects of customer violence experiences, protection systems, and monitoring systems on the subjective health status of salespersons and electronic machine repairers. Methods: A total of 934 persons were sampled nationwide, including 582 salespersons and 352 electronic machine repairers, from March 2~30, 2020 and asked to fill out a self-reported questionnaire. Results: The findings show that electronic machine repairers were more exposed to customer violence and had a weaker protection system than salespersons. They also experienced severe control from management through a monitoring system. The regression analysis revealed that verbal violence had a negative impact on the subjective health status of electronic machine repairers (p=.021). A worker protection system had significant effects on the improved subjective health status of salespersons (p=.009). Depression and fatigue had negative impacts on the subjective health status of both salespersons (depression: p<.001, fatigue: p<.001) and electronic machine repairers (depression: p<.001, fatigue: p=.002). Conclusion These findings put a greater emphasis on the need for worker protection systems to prevent workplace violence and a health promotion program to manage depression and fatigue in workplaces.

PURPOSE: This study identified the influence of hotel workers' emotional labor and social support on their intentions to change jobs. METHODS: Study participants were 437 workers from seven hotels in Korea who consented to the survey. Among them, insufficient responses from 21 participants were excluded, as well as 107 responses from workers with workloads of under one hour of face to face work. Thus, 309 hotel workers were included in the final analysis. A multivariate regression analysis was used to identify factors influencing the hotel workers' intention to change jobs. RESULTS: The intention to change jobs was high when external behavior was shown, and workers who received social support from a superior exhibited low intention of changing jobs. CONCLUSION The study results show that the most influential variables of turnover intention are external behavior and the support of a superior. It is therefore important to educate managers on personnel management methods for reducing external behaviors so that the rate of job changes by hotel workers can be reduced. It is also necessary to prepare and manage measures for strengthening the support system by workplace superiors.

PURPOSE: The purpose of this study was to understand the present status of the work performance of the construction industry health managers and the developmental direction for the construction industry health management. METHODS: The subjects of this study were 149 health managers working in the construction industry. Data of a total of 130 participants were analyzed by excluding the missing data among field workers. The contents of the survey were the characteristics of the workplace, the difficulties and requirements of health management, and the level of job performance. RESULTS: The factors affecting measuring work environment task were age, number of workers, number of safety managers, and lack of support from the headquarters. The factors affecting managing work environment and physicochemical harmful factors were age, type of contract and conflicting business opinions. The factors affecting implementing health examination were age, type of contract, and number of safety managers. The factors affecting healthcare were age, type of contract, number of safety manager, presence of healthcare room, and conflicting business opinions. CONCLUSION It is necessary to provide practical guidance and practical resources, and education for strengthening capacity. The support for business owners and managers support is needed.

PURPOSE: We investigated the prevalence and risk factors of allergic rhinitis (AR), nationwide in random children and adolescents of Korea. METHODS: A modified International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire survey was done in 1,820 children from elementary, middle, and high school nationwide in Korea. The subjects were selected by the stratifying sampling method by school grade and five regions. Current AR was defined as having AR symptoms during the last 12 months with a history of physician-diagnosed AR. Skin prick tests for 18 common allergens were performed. RESULTS: The number of males was 945, and that of females was 875. The mean age of the patients was 12.61+/-3.40 years. The prevalence of current AR and atopic current AR were 29.0% and 18.7%, respectively. Risk factors for current AR were male (adjusted odds ratio [aOR], 1.486; 95% confidence interval [CI], 1.189-1.856), family history of paternal AR (aOR, 3.208; 95% CI, 2.460-4.182), family history of maternal AR (aOR, 3.138; 95% CI, 2.446-4.025), antibiotic use in infancy (aOR, 1.547; 95% CI, 1.228-1.949), mold exposure during infancy (aOR, 1.416; 95% CI, 1.103-1.819), mold exposure during the last 12 months (aOR, 1.285; 95% CI, 1.012-1.630), and sensitization on skin prick tests (aOR, 2.596; 95% CI, 2.055-3.279). Risk factors for atopic current AR were the same as those of current AR, whereas breast-milk feeding (aOR, 0.720; 95% CI, 0.530-0.976) was a protective factor. Sensitized allergens as risk factors for current AR were Dermatophagoides pteronyssinus, Dermatophagoides farina, ragweed, mugwort, oak, alder, birch, Japanese hop, cat, and dog. CONCLUSION: The prevalences of current AR and atopic current AR were 29.0% and 18.7%, respectively. Male, sex parental AR, antibiotic use in infancy, mold exposure during the last 12 months, mold exposure during infancy, and atopic sensitization were risk factors for current AR. Breast-milk feeding was a protective factor for atopic current AR. Aeroallergen sensitization was an important risk factor for AR.

Wheat is the most widely cultivated grain and an important source of food and dietary protein. Wheat proteins are classified based on extraction in different solvents, which are albumin, globulin, prolamin (gliadin) and glutenin. The term 'gluten' contains approximately equal amounts of gliadin and glutenin and is the major determinant of the properties of wheat flour conferring cohesiveness and viscoelasticity that allows its dough to be processed into many kinds of food. Gluten is known to be responsible for triggering celiac disease and wheat allergy. Wheat allergy is primarily an IgE-mediated response. Clinical manifestations of wheat allergy are similar to those of other food allergies, with symptoms on the skin, gut and respiratory tract. Recent studies have shown that IgE to gliadin can be an indicator for risk of severe immediate reaction-like anaphylaxis and wheat-dependent, exercise-induced anaphylaxis (WDEIA). However, current in vitro test reagents for the diagnosis of wheat allergy mainly contain water-soluble wheat protein and a small amount of gluten, so there are some limitations to diagnose gluten allergy. Furthermore, there is no acceptable method to measure gluten in food products for preparing effective gluten-free diet. To overcome these limitations and to improve quality of life of wheat allergy sufferers, more work is needed. We report a case of a 4-year-old boy with gluten allergy who presented with urticaria after ingestion kneaded wheat flour with a brief review of the literature.
