PURPOSE: The purpose of this study was to investigate the welfare status of nurses and the status of fixed night shifts and flexible work arrangements in both general hospitals and advanced general hospitals in Korea. METHODS: A total of 167 hospitals participated in this study, done from April to October 2018. RESULTS: There were 103 hospitals utilizing the fixed night shift system, 22 in the two-shift system, 3 in the fixed holiday shift, 79 in the fixed shift system, and 39 in the short-time working system. The average welfare benefits for nurses increased to 33.02 million won on average. However, welfare services for the nurses were poor: 41.8% of the respondents had a nurses' lounge, 81.7% were given dormitory space at their place of employment, 41.8% had access to welfare facilities, and 56.4% were provided with welfare support countermeasures. CONCLUSION: The results show an increasing trend of hospitals to utilize fixed night shift and flexible work arrangements. An institutional strategy at the national policy level should be established to implement flexible work arrangements including the fixed night shift system, which has a poor level of welfare.

PURPOSE: Vitamin D deficiency is reported to be more common in type 1 diabetes patients and might be associated with the increased urinary loss of vitamin D binding protein (VDBP) consequent to impaired 25-hydroxyvitamin D (25(OH)D) circulation. We aimed to evaluate the possible increased urinary loss of VDBP, a correlation between VDBP and circulating 25(OH)D level, and risk factors influencing low vitamin D level in pediatric type 1 diabetes patients without microalbuminuria. METHODS: This is a cross-sectional study of subjects who visited Seoul National University Children’s Hospital between January and March 2013. Forty-two type 1 diabetes patients and 29 healthy controls were included. Biochemical parameters including serum and urine VDBP concentrations were analyzed. RESULTS: There was no significant difference in the frequency of vitamin D deficiency or serum 25(OH)D level between the 2 groups. The serum and urine VDBP concentrations did not show any difference between the 2 groups. Serum 25(OH) D level did not correlate with serum or urine VDBP. Multivariate regression analysis revealed that daylight outdoor hours (β=2.948, P=0.003) and vitamin D intake (β=2.865, P=0.003) affected the 25(OH)D level; the presence of type 1 diabetes or urinary VDBP excretion was not significant. CONCLUSIONS: In pediatric type 1 diabetes patients, urinary VDBP excretion did not contribute to low serum 25(OH)D level in the setting of normoalbuminuria. The factors associated with 25(OH)D level during winter periods were daylight outdoor hours and vitamin D intake. Further studies including both micro- and macroalbuminuria patients with type 1 diabetes are warranted.

PURPOSE: The purpose of this study was to examine nursing organizational culture and resilience and their effects on quality of nursing service. METHODS: A cross-sectional study was conducted. A convenience sampling method was used to collect data from 199 participants who worked in a tertiary hospital in G city. Demographic and work related variables, quality of nursing service, resilience, and nursing organizational culture were measured using validated self-report questionnaires. RESULTS: All of the participants were women and the majority were staff nurses and single. A statistically significant difference in quality of nursing service was found for age, marital status, educational level, clinical career, position and perceived health status. Age, educational level, clinical career, position, resilience, innovation-oriented culture, relation-oriented culture, and hierarchy-oriented culture were significant predictors of quality of nursing service, explaining 47% of total variance. Among the predictors, resilience was the strongest predictor, followed by innovation-oriented culture, and hierarchy-oriented culture. CONCLUSION: Findings indicate that quality of nursing service can be improved by raising individual nurse's resilience and advancing nursing organizational culture. Considering the identified factors, researchers and administrators need to develop and provide clinical nurses with a variety of programs to improve the quality of their nursing service.

Primaquine was approved for treatment of malaria in 1952 by the United States Food and Drug Administration (FDA). It has remained the only FDA-licensed drug capable of clearing the intra-hepatic schizonts and hypnozoites of Plasmodium vivax. It is associated with serious hazards and side effects, such as hemolytic anemia and methemoglobinemia. However, there is no report of primaquine causing liver injury in Korea. We describe a case of acute liver failure following primaquine overdose in a 19-year-old man.

BACKGROUND/AIMS: Systemic inflammatory response syndrome (SIRS) can induce occurrence of oxidative stress. Several reports have evaluated selenium supplementation in SIRS patients with encouraging results. Therefore, we evaluated the effect of intravenous high-dose selenium supplementation in patients with SIRS. METHODS: Patients were randomly assigned to one of two groups: the selenium group (800 microg/day of selenoic acid by intravenous bolus injection for 7 days) or the placebo group. Physical and biochemical measurements were used to assay acute phase reactants, severity of illness index and serum selenium concentration. RESULTS: A total of 23 patients classified as mild-to-moderate severity of illness index were enrolled between March 2010 and October 2011. Serum selenium concentration increased in the selenium group after intervention, but there was no significant change in the placebo group. In the selenium group, the white blood cell (WBC) count, serum level of c-reactive protein (CRP), Acute Physiology and Chronic Health Evaluation II (APACHEII) score and Sequential Organ Failure Assessment (SOFA) score improved significantly by days 7 and 14 compared with day 0. In the placebo group, only the serum CRP level at day 14 and APACHE II score at days 7 and 14 improved significantly compared to day 0. CONCLUSIONS: Intravenous supplementation with high-dose selenium improved acute phase reactants and the severity of illness index in patients with SIRS. However, larger prospective clinical trials are required to determine the efficacy of selenium supplementation in SIRS patients.

Dengue fever is an acute febrile disease caused by the dengue virus. As the numbers of reported patients with dengue fever are increasing, rare complications associated with dengue fever, such as rhabodomyolysis or meningitis, are increasing in Korea. We describe the case of a Korean male presenting with fever, myalgia, nausea, diarrhea and blurred vision, who as a result of serologic test and fundoscopy, was diagnosed with dengue fever complicated by retinitis. He completely recovered with conservative care.

Sequential lymphoma is defined as two different types of lymphoma that occur in the same patient at different anatomic sites and times. In most cases, the two distinct histologies belong to the same lineage (B- or T-cell lymphoma), though cases with both have been observed. A few cases of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphomas arising in patients with angioimmunoblastic T cell lymphoma (AITL) have been reported. Immune deficits inherent in AITL, combined with the immunosuppressive effects of the therapy, may have allowed unchecked EBV-induced proliferation of latently or newly EBV-infected B cells with eventual clonal selection and progression to aggressive B-cell lymphoma. Here, we report a case of AITL in which EBV-positive diffuse large B-cell lymphoma (DLBCL) arose 9 months after the initial diagnosis of AITL.

PURPOSE: This study analyzed the effectiveness of poly (lactic-co-glycolic acid) (PLGA) as a tissue recovery agent and determines the in vivo safety and efficacy of microparticle-based PLGA. MATERIALS AND METHODS: Fifteen 3-month-old male white rabbits were used. Allogenic adipose tissue derived stromal vascular fraction (SVF) was cultured and labeled with the fluorescent dye PKH26. The rabbits were divided into 4 groups: the SVF group, the PLGA group, the normal control group, and the disease control group. The right corpus cavernosal tissue of the rabbits was surgically removed in the selected portion, except in the normal control group. The defect space of each rabbit was replaced with 10(6) SVF cells in the SVF group and 0.1 g of biodegradable polymer solution in the PLGA group. Microscopic confirmation and analysis of tissue regeneration were performed after 8 weeks. Using confocal microscopy, the nuclei of the smooth muscle cells and SVF migration were examined. The composition of smooth muscle and fibrosis of the injured corpus cavernosum were compared and analyzed by Masson's trichrome stain. RESULTS: There were no signs of migration or rejection of the injected materials in any of the experimental groups. The mean amount of smooth muscle in the normal control group was 15.25+/-1.34 microm2 (right) and 13.90+/-0.703 microm2 (left); in the disease control group it was 11.10+/-0.87 microm2 (right) and 12.80+/-1.01 microm2 (left); in the SVF group it was 13.82+/-4.10 microm2 (right) and 13.96+/-3.94 microm2 (left); and in the PLGA group it was 12.89+/-1.39 microm2 (right) and 13.24+/-1.43 microm2 (left). Only the disease control group showed significant decreased smooth muscle in the left cavernosum (p<0.05). No significant difference was found between the left and right side of each rabbit's cavernosal smooth muscle in the SVF or PLGA group (p>0.05). Furthermore, no difference was found between any two groups (normal control versus SVF (p=0.705), normal control versus PLGA (p=0.88), SVF versus PLGA (p=0.23). CONCLUSIONS: PLGA microparticles had the same tissue restoring effect when compared with SVF and no adverse effect or migration of particles was found through the injection of PLGA or SVF. PLGA is safe and has the proper tissue recovery effect, saving additional tissue harvesting.

BACKGROUND/AIMS: Fabry disease is an X-linked recessive and progressive disease caused by alpha-galactosidase A (alpha-GaL A) deficiency. We sought to assess the prevalence of unrecognized Fabry disease in dialysis-dependent patients and the efficacy of serum globotriaosylceramide (GL3) screening. METHODS: A total of 480 patients of 1,230 patients among 17 clinics were enrolled. Serum GL3 levels were measured by tandem mass spectrometry. Additionally, we studied the association between increased GL3 levels and cardiovascular disease, cerebrovascular disease, or left ventricular hypertrophy. RESULTS: Twenty-nine patients had elevated serum GL3 levels. The alpha-GaL A activity was determined for the 26 patients with high GL3 levels. The mean alpha-GaL A activity was 64.6 nmol/hr/mg (reference range, 45 to 85), and no patient was identified with decreased alpha-GaL A activity. Among the group with high GL3 levels, 15 women had a alpha-GaL A genetics analysis. No point mutations were discovered among the women with high GL3 levels. No correlation was observed between serum GL3 levels and alpha-GaL A activity; the Pearson correlation coefficient was 0.01352 (p = 0.9478). No significant correlation was observed between increased GL3 levels and the frequency of cardiovascular disease or cerebrovascular disease. CONCLUSIONS: Fabry disease is very rare disease in patients with end-stage renal disease. Serum GL3 measurements as a screening method for Fabry disease showed a high false-positive rate. Thus, serum GL3 levels determined by tandem mass spectrometry may not be useful as a screening method for Fabry disease in patients with end stage renal disease.
