BACKGROUND: Severe or massive postpartum hemorrhage (PPH) has remained a leading cause of maternal mortality for decades across the world and it results in critical obstetric complications. Recombinant activated factor VII (rFVIIa) has emerged as a gold standard adjunctive hemostatic agent for the treatment of life-threatening PPH refractory to conventional therapies although it remains off-licensed for use in PPH. We studied the effects of rFVIIa on coagulopathy, transfusion volume, prognosis, severity change in Korean PPH patients. METHODS: A retrospective review of medical records between December 2008 and March 2011 indicating use of rFVIIa in severe PPH was performed. We compared age, rFVIIa treatment, transfusion volume, and Sequential Organ Failure Assessment (SOFA) score at the time of arrival in the emergency department and after 24 hours for patients whose SOFA score was 8 points or higher. RESULTS: Fifteen women with SOFA score of 8 and above participated in this study and eight received rFVIIa administration whereas seven did not. Patients' mean age was 31.7 ± 7.5 years. There was no statistically significant difference in initial and post-24 hours SOFA scores between patients administered rFVIIa or not. The change in SOFA score between initial presentation and after 24 hours was significantly reduced after rFVIIa administration (P = 0.016). CONCLUSIONS: This analysis aimed to support that the administration of rFVIIa can reduce the severity of life-threatening PPH in patients. A rapid decision regarding the administration of rFVIIa is needed for a more favorable outcome in severe PPH patients for whom there is no effective standard treatment.

PURPOSE: The purpose of this study was to study the effects of the reeducation of core fundamental nursing skills on clinical stress, critical thinking disposition, and self-confidence in nursing skills of senior nursing students. METHODS: A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Participants were recruited from two nursing colleges. The sample consisted of an intervention group (n=33) that participated in the educational program and a control group (n=32). The data were collected using self-administered questionnaires. Data analyses utilized χ²-test & t–test. RESULTS: After the reeducation of core fundamental nursing skills, senior nursing students had less clinical stress (t=-2.089, p=.041) and more self-confidence (t=1.008, p=.318) in nursing skills. However, it had no effect on critical thinking disposition (t=1.008, p=.318). CONCLUSION: Reeducation of core fundamental nursing skills is important to the nursing profession. Also, nurses who are self-confident in their nursing skills are less stressed about improving the quality of their work due to the reeducation of core fundamental nursing skills. Therefore, it is vital for nursing colleges to reeducate core fundamental nursing skills to their students before graduation.

From January 2007 to June 2012, 55 autopsy cases were reviewed, in which death occurred outside the hospital and the patients were declared dead on arrival at the emergency departments, in order to compare the clinical and postmortem examination diagnoses of death-on-arrival patients in tertiary hospitals in Busan, Yangsan and Ulsan city. Of 22 non-traumatic deaths, 21 occurred from natural causes and 1 from unknown cause (sudden infant death syndrome, SIDS). Clinical diagnoses were cardiovascular diseases or "non-traumatic" / "unknown" while autopsy diagnoses were majorly cardiovascular diseases, especially coronary artery diseases (72.7%). Of 33 unnatural deaths, the cause of death was blunt trauma in 4 patients, sharp-force injury in 6, falling in 10, gunshot injury in 1, traffic accidents in 3, asphyxia in 2, drowning in 2, fire-related death in 1, and intoxication in 4. There were no definite discrepancies between clinical and autopsy diagnoses, except for 5 non-traumatic deaths and 2 unnatural deaths. These results suggest that the role of the emergency department may be crucial in postmortem investigations.

Purpose: The purpose of this study was to investigate factors affecting the quality of life of middle-aged women with urinary incontinence by using Wilson and Cleary (1995)'s health-related quality of life model and previous studies. This article was done to construct a model for the collection of data on women with urinary incontinence and verifying the suitability of the model and the hypotheses presented in the model. Methods: A total of 209 valid questionnaires which met the criteria of middle-aged women who experienced urinary incontinence was used for final analysis. The exogenous and endogenous variables of the hypothesis model consisted of age, number of delivery, menstrual status, self-esteem, social support, physical symptoms, depression, anxiety, self-care agency and quality of life. The data were analyzed using IBM SPSS/WINdow 25.0 and AMOS 18.0 program. Results: The fitness of the modified model, x2/df=1.675, RMR=0.047, RMAEA=0.057, GFI=0.900, AGFI=0.855, NFI=0.923, TLI=0.957, CFI=0.9674. In the modified model, self-esteem showed the strongest total impact including the direct and indirect impacts on the quality of life of women with incontinence. In the result of verification of the modified model, quality of life explained by 58.8% through self-esteem, social support, self-care agency. Conclusion Efforts are needed to improve self-esteem for middle-aged women with urinary incontinence, alleviate psychological symptoms, and develop self-care agency that they can manage themselves. Various aspects of physical, mental and psychological aspects can be comprehensively assessed and utilized to develop an interactive strategy system through individual programs and social support.

Objective: Urgent upper endoscopy is performed to achieve acute hemostasis in patients with high-risk bleeding sources. Emergency physicians must identify patients who require urgent endoscopic treatments. This study assessed the performance of blood urea nitrogen (BUN) for predicting severe bleeding that necessitates urgent endoscopic hemostasis compared to the risk assessment scores in patients with acute non-variceal upper gastrointestinal bleeding (ANVUGIB). Methods: The presumed ANVUGIB patients were classified into endoscopic and non-endoscopic hemostasis groups. Data including historical features, symptoms, signs, and routine laboratory tests were collected and compared. Results: Three hundred and ninety-one patients were analyzed, including 116 patients in the endoscopic hemostasis and 275 patients in the non-endoscopic hemostasis group. In the area under curve (AUC) of the receiver operator characteristic curve, BUN (AUC 0.733; 95% confidence interval [CI], 0.681-0.785) and BUN/creatinine (AUC, 0.727; 95% CI, 0.672-0.783) were superior to total protein, Glasgow-Blatchford score (GBS), modified GBS (AUC, 0.649, 0.623 and 0.646, respectively) for predicting endoscopic hemostasis. Pre-endoscopy Rockall score and AIMS65 were statistically insignificant. The same results were obtained when the patients with liver and chronic kidney diseases were excluded. Conclusion The current results suggest that BUN was an independent predictor of endoscopic hemostasis in patients with ANVUGIB. Further studies will be needed to determine if BUN can be used in clinical practice.

In this study, we investigated the molecular characteristics of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae isolates that were recovered from an outbreak in a Korean hospital. A new multilocus sequence typing (MLST) scheme for K. pneumoniae based on five housekeeping genes was developed and was evaluated for 43 ESBL-producing isolates from an outbreak as well as 38 surveillance isolates from Korea and also a reference strain. Overall, a total of 37 sequence types (STs) and six clonal complexes (CCs) were identified among the 82 K. pneumoniae isolates. The result of MLST analysis was concordant with that of pulsedfield gel electrophoresis. Most of the outbreak isolates belonged to a certain clone (ST2), and they produced SHV-1 and CTX-M14 enzymes, which was a different feature from that of the K. pneumoniae isolates from other Korean hospitals (ST20 and SHV-12). We also found a different distribution of CCs between ESBL-producing and -nonproducing K. pneumoniae isolates. The MLST method we developed in this study could provide unambiguous and well-resolved data for the epidemiologic study of K. pneumoniae. The outbreak isolates showed different molecular characteristics from the other K. pneumoniae isolates from other Korean hospitals.

PURPOSE: These days, airline traffic is so developed that the globe has become much smaller and interest in fear of passenger-flight crashes is increasing. Using the opportunity offered by the Kimhae airline disaster, the author studied the relation of the injury mechanism & the seat-position to the injury severity in order to provide helpful information for use in other situations. METHODS: The author performed a retrospective analysis and compared survivors (37 persons) with deaths (129 persons) in the crash of Chinese passenger-flight B767-200 approaching Kimhae airport on April 15, 2002. RESULTS: Most of the survivors were seated in the rear of the airplane while most of those who died were in the front. Thus, a definite correlation exists between seat position in the aircraft and the injury severity. The deceleration force generated during a flight crash is sufficient to induce fatal injury. CONCLUSION: Most flight crashes are due to CFIT (controlled flight into terrain) accidents which are caused by the pilot being insensible to safety. This time, it was also the case. The author wishes it not to be the case next time.

BACKGROUND: Life expectancy is ever increasing due to medical advancements, but cancer death rate is also increased. Quality of life is an important issue in cancer patients. Despite developments of early diagnosis and treatments for cancer, the medical costs is increasing due to exfended sarvival against cancer and the absolute numbers of terminal cancer patients. We assessed the medical costs and quality of life in terminal cancer patients by the types of medical facilities, which would contribute to effective management. METHOD: A total 159 patients(males 70, females 89) with terminal cancer patients who were treated and died in various types of medical facilities(home hospice, charity hospital hospice unit, university hospital hospice unit, university hospital non-hospice unit) between November 1, 1997 and January 31, 1999 were included in the study. After the confirmation that the demographic factors correlated with factors of quality of life, the differences in the medical costs and quality of life(pain, depression, ADLs, family APGAR score) during the last 1 week of life in the various types of medical facilities analyzed by multi-way ANOVA with interaction of the significant demographic factors. RESULTS: The mean cost of types of medical facilities during the last week of patients as 65332.5 won in charity hospital hospice unit, 105165.5 won in home hospice, 702083.4 won in university hospital hospice unit, and 1037358.6 won in university hospital non-hospice unit. The difference between free hospital hospice unit and home hospice in medical costs as not statistically significant, but the difference among charity hospital hospice unit and home hospice, university hospital hospice unit, and university hospital non-hospice unit as significant (p<0.001). The demographical factors of quality of life in terms of pain, depression, ADLs, and family APGAR score were compared among various facilities. The ADL score of home hospice was 8.2 +/- 3.3, which was lower than free hospital hospice unit and university hospital hospice unit(p<0.05). The mean pain scor of home hospice as 1.7+/-1.7 and that of university hospital hospice as 1.2+/-1.2, and pain scores of home hospice were lower than free hospital hospice unit, and pain scores of university hospital hospice were lower than free hospital hospice unit and university hospital non-hospice unit(p<0.05). In depression's categorial scale of home hospice the score was 4.8+/-1.3, which was higher than those of free hospital hospice unit and university hospital non-hospice unit(p<0.05), signifying less depression. The family APGAR score was statistically insignificant among various types of medical facilities. CONCLUSION: The cost of hospice care is less than the non-hospice care. We found that the patients of home hospice experienced less pain and depression even with low ADLs, and increased the quality of life in both psychological and physical aspects.

Nitrogen is an inert gas that is harmless to humans under normal conditions. While it is not inherently toxic, nitrogen gas becomes dangerous when it displaces oxygen, resulting in suffocation. Herein, we report a case of a 34-year-old man who attempted suicide by nitrogen asphyxiation who presenting with decreased mental function and agitation. Lactic acidosis and hyperammonemia were observed on presentation at the emergency department, but these improved after a few hours. After 2 days, the patient regained full consciousness, and was discharged without any complications. Survival after asphyxiation due to nitrogen gas is very rare, and these patients are more likely to have poorer outcomes. There is a potential for the increasing use of nitrogen gas as a method of committing suicide because of the ease of access to this gas.
