PURPOSE: The purpose of this study was to identify the relation between violence experiences and the professional quality of life for hospital nurses. METHODS: The participants for this study were 212 nurses in one general and three special hospitals located in the metropolitan area of Seoul, South Korea. Data gathered through October and November 2013 were analyzed using descriptive statistics and chi2 test. RESULTS: Nurses experienced verbal violence, physical threats and physical violence more frequently from patients and their families rather than from doctors or peer nurses. Nurse's compassion satisfaction was low when nurses experienced violence from peer nurses. Burnout was high when nurses experienced violence from doctors, peer nurses, patients and their families. Secondary traumatic stress was affected by violence from patients and their families. The professional quality of life of nurses was associated with violence from doctors, peer nurses, patients and their families. Of the nurses, 69.3% answered that formation of a positive organizational culture would be the most effective measure for prevention of violence in hospitals. CONCLUSION: The formation of positive organizational culture, development of violence intervention policies and education are crucial to improve the professional quality of hospital nurses' life.

Ovarian hemangiomas are very uncommon and most are of the cavernous type. A few reports have described the radiologic findings of this neoplasm, but as far as the author is aware, the literature contains no description of calcified cavernous hemangioma. A case in which this condition involved the ovary is now reported.

Objectives: This study aimed to examine the frequency of convenience food consumption at convenience stores (CVS) and the CVS usage patterns of middle and high school students as well as to understand students’ attitude toward sodium and sugar reduction. Methods: We used an online questionnaire for data collection. The questionnaire comprised five distinct categories: general characteristics, CVS usage, frequency of consumption according to convenience food menus at CVS, attitude toward sodium and sugar reduction, and adherence to dietary guidelines. Results: A total of 75 students from Seoul (14 middle school students and 61 high school students) participated in the study. Most respondents visit CVS 3-5 times a week. CVS are predominantly used during weekdays, mostly during lunch, and dinner. The students mostly checked the caloric content and expiration date as food labeling information. The participants were aware of the need to reduce their sugar and sodium intake. Among frequent CVS convenience food consumers, there was an increased consideration of the need to reduce their sugar and sodium consumption, despite their actual selection of foods with high sugar and sodium content. Additionally, they did not check the sugar and sodium levels indicated in food labeling. Further, the dietary action guide from the Ministry of Health and Welfare were poorly followed by most students. Conclusions There is a need for nutrition education specifically addressing the sugar and sodium content of the convenience foods predominantly consumed by students. Additionally, educating students with frequent convenience food consumption to actively check the sugar and sodium information on food labels could help promote healthier food choices.

Forty-one strains of Streptococcus pneumoniae were isolated at Seoul National University Children's Hospital from 1991 to 1997. Isolates were divided into six groups based on MICs of three quinolones, ciprofloxacin, ofloxacin and norfloxacin. Sequencing showed that the isolates which were intermediately resistant to three quinolones or resistant to at least one kind of quinolone had one missense mutation, Lys137-->Asn(AAG-->AAT) substitution in the ParC subunit of topoisomerase IV without additional mutation in QRDR of the GyrA subunit of DNA gyrase. In conclusion, the ParC subunit of DNA topoisomerase IV is the primary target site for fluoroquinolone in S. pneumoniae and Lys137-->Asn substitution renders the quinolone resistance in S. pneumoniae.

Mesalazine suppositories are widely used to treat ulcerative colitis and have a guaranteed safety profile, but although rare, they can cause pulmonary toxicity. A 35-year-old woman with ulcerative colitis was diagnosed to have acute eosinophilic pneumonia after 29 days of oral mesalazine use and improved after mesalazine and corticosteroid were withdrawn. Reintroduction of mesalazine suppositories resulted in acute eosinophilic pneumonia recurrence after 28 days. Mesalazine re-administration (even via a different route) in patients with a history of mesalazine-induced eosinophilic pneumonia should be undertaken cautiously, because eosinophilic pneumonia may recurrence.

PURPOSE: The purposes of this study were to compare confidence in practice of intermittent gavage tube feeding and participants' satisfaction by three types of feedback; professor verbal feedback, professor feedback with smartphone video, and peer feedback with smartphone video. In addition, frequently failed items in the intermittent gavage tube feeding procedure were analyzed. METHODS: Data were collected from a convenience sample of 78 nursing college students in November 2014. Students were randomly assigned to the control group, experimental group I (smartphone video with professor feedback) or group II (smartphone video with peer feedback). Data were analyzed using descriptive statistics including chi-square test, ANOVA, and Scheffe test with SPSS 21.0. RESULTS: Confidence in practice of intermittent gavage tube feeding and satisfaction with feedback were highest in experimental group I that had professor feedback with smartphone video. For the procedure, the most frequently failed item was giving an explanation to patients about the purpose and the procedure of tube feeding. CONCLUSION: The results indicate that professor verbal feedback with smartphone video is the most benefit to the nursing students in acquiring core nursing practice skills.

The metal chromium is widely used in industry. Hexavalent chromium is a strong oxidizing agent, and exposure to some hexavalent compounds can cause serious problems, such as skin ulcers, acute gastroenteritis, acute tubular necrosis with renal failure, and hepatic necrosis. We report a case of acute kidney injury following skin exposure to hexavalent chromium, which burned a relatively small percentage of the total body surface area (TBSA). A 49-year-old man developed oliguria and acute kidney injury 3 days after burning about 5% of his TBSA with chromic acid solution, causing second-to third-degree chemical burns. His creatinine level increased to 12.5 mg/dL. The patient underwent hemodialysis with supportive care. His renal function improved and the dialysis was discontinued. The serum and urine chromium concentrations also decreased.

BACKGROUND: Heart rate (HR) is an essential vital sign based on the finding that HR beyond its normal range is associated with several conditions or diseases, including high mortality in several clinical settings. Nevertheless, the clinical implications of HR remain unresolved in patients undergoing continuous renal replacement therapy (CRRT). METHODS: This retrospective cohort study included 828 patients who underwent CRRT due to acute kidney injury between 2010 and 2014. HR and other baseline parameters at the time of CRRT initiation were retrieved. The odds ratio (OR) of 30-day mortality was calculated using a multivariate logistic model. RESULTS: CRRT significantly lowered the HR of patients such that the pre- and post-CRRT HRs (average 6 hours) were 107 beats/min and 103 beats/min, respectively (P < 0.001). When we explored the relationship with 30-day mortality, only HR at the time of CRRT initiation, but not pre- or post-CRRT HR, had a significant relationship with mortality outcome. Based on this result, we divided patients into quartiles of HR at the time of CRRT initiation. Mortality OR in the 4th quartile HR group was 2.6 (1.78–3.92) compared with the 1st quartile HR group. This relationship remained consistent despite adjusting for 28 baseline covariates: OR, 1.7 (1.09–2.76); P = 0.020. However, HR was not associated with the weaning rate from CRRT. CONCLUSION: High HR at the time of CRRT initiation is subsequently related with high mortality. These results can be a basis for a future predictive model of CRRT-related mortality.

PURPOSE: This study aimed to evaluate the clinical findings in pediatric rhabdomyolysis and the predictive factors for acute kidney injury (AKI) in Korean children. METHODS: Medical records of 39 Korean children, who were newly diagnosed with rhabdomyolysis from January 2008 to December 2015, were retrospectively analyzed. The diagnosis was made from the medical history, elevated serum creatinine kinase level >1,000 IU/L, and plasma myoglobin level >150 ng/mL. Patients with muscular dystrophy and myocardial infarction were excluded. RESULTS: The median patient age at diagnosis was 14.0 years (range, 3–18 years), and the male to female ratio was 2.5. The most common presenting symptom was myalgia (n=25, 64.1%), and 14 patients (35.9%) had rhabdomyolysis-induced AKI. Eighteen patients (46.2%) had underlying diseases, such as epilepsy and psychotic disorders. Ten of these patients showed rhabdomyolysis-induced AKI. The common causes of rhabdomyolysis were infection (n=12, 30.7%), exercise (n=9, 23.1%), and trauma (n=8, 20.5%). There was no difference in the distribution of etiology between AKI and non-AKI groups. Five patients in the AKI group showed complete recovery of renal function after stopping renal replacement therapy. The median length of hospitalization was 7.0 days, and no mortality was reported. Compared with the non-AKI group, the AKI group showed higher levels of peak creatinine kinase and myoglobin, without statistical significance. CONCLUSION: The clinical characteristics of pediatric rhabdomyolysis differ from those observed in adult patients. Children with underlying diseases are more vulnerable to rhabdomyolysis-induced AKI. AKI more likely develops in the presence of a high degree of albuminuria.

Tyrosine kinase (TK) inhibitors are most common used to treat chronic myeloid leukemia (CML). Several studies describe a range of adverse effects of TK inhibitors on the kidney in adult patients, including nephrotic syndrome. However, there are only a few pediatric case reports on TK inhibitor-associated nephrotic syndrome. We report a case of nephrotic syndrome associated with dasatinib, a type of TK inhibitor, in a child who suffered from both the underlying idiopathic nephrotic syndrome and CML. A 14-year-old Korean boy was diagnosed with steroid dependent nephrotic syndrome at 4 years old and CML at 11 years old. He developed a relapse of nephrotic syndrome after treatment with TK inhibitors, especially dasatinib, which he used for four months. Despite receiving steroid pulse therapy due to his underlying steroid dependent nephrotic syndrome, his proteinuria did not respond. He discontinued dasatinib medication due to the possibility to dasatinib induced nephrotic syndrome.After one week, his nephrotic syndrome improved. The case is important because if a CML patient that has been on a TK inhibitor develops a newly onset nephrotic range proteinuria, TK inhibitor-induced nephrotic syndrome should be included in the differential diagnosis.
