1.Effects of Traumatic Events, Compassion Fatigue, Self-esteem, and Compassion Satisfaction on Burnout of Nurses in Emergency Department (ED).
Korean Journal of Occupational Health Nursing 2014;23(2):80-88
PURPOSE: The purpose of this study is to verify the factors that determines burnout of nurses in emergency department. METHODS: The survey was given to 170 ED nurses which are located in Busan from July 1st to August 31st of 2012. The results were analyzed by descriptive statistics, t-test, ANOVA, pearson correlation coefficients and stepwise multiple regression using SAS 9.2 program. RESULTS: There were statistically significant differences in burnout depending on gender, position, workplace satisfaction, job satisfaction. Significant positive correlation between compassion fatigue and burnout was found. Also significant negative correlation was found between self-esteem, compassion satisfaction and burnout. Factors influencing burnout were self-esteem, compassion satisfaction and compassion fatigue with R2 value 58.0%. CONCLUSION: Considering these results, it seems that great efforts will be needed for reducing burnout by mitigating the emergency nurses' compassion fatigue and introducing programs to increase the self-esteem and compassion satisfaction.

The superior volume maintenance of membranous over endochondral bone grafts, which was shown in several studies has provided the basis for its preferred clinical use as an onlay grafting material on the craniofacial skeleton. The scientific rationale for this seeming embryological advantage, however, has never been proven, Since the cortical component of membranous bone is proportionally greater than that of endochondral bone, it follows that membranous grafts would show greater volume maintenance over time. Our hypothesis is that the pattern of onlay bone graft resorption is primarily determined by a graft's micro-architecture (relative cortical and cancellous composition) rather than its embryololgical origin(membranous versus endochondral). Fourty adult New Zealand white rabbits were used for this study. There were 8 animals in each of 4 groups. The rabbits of each group were sacrificed at 3, 8, and 16 weeks. Four types of grafts were placed subperosteally, onto each rabbit's cranium: a hydroxyapatite, a cortical bone graft of membranous origin, a cortical bone graft of endochondral origin and a cancellous bone graft of endochondral origin. Membranous bone grafts were obtained from the lateral mandible and endochondral bone grafts were obtained from the ileum. In order to determine post-sacrifice volume and density of the bone grafts, a caliper technique and bone densitometry(bone densitometer: LUNAR, DPX-L, U.S.A.) were performed on all of the bone grafts. Bone graft specimens were histologically examined at 3, 8, and 16 weeks.The measurement of volume and density show that there is a statistically greater resumption in the cancellous endochondral bone grafts for all parameter, compared to either the endochondral or membranous cortical bone grafts or hydroxyapatite at all time points(p< 0.05). In addition, there is no significant difference in the resorption rates between the endochondral and membranous cortical bone grafts for all parameters at all time points. By placing cortical bone grafts and cancellous bone grafts on the recipient sites separately, we have shown that the former grafts maintain their volumes, widths and projections significantly better than the latter grafts. Futhermore, we found no statistical difference in resorption rates between the two cortical bone grafts of different embryologic origins, a finding which has never been previously shown. Bone volume fraction, measured with bone densitometry, was shown to be higher in cortical bone than in cancellous bone at all time points, further illustrating the differences between cortical and cancellous bone.From our results, we believe cortical bone to be a superior onlay-graftiong material, independent of its embryololgic origin.

The endoscopic variceal ligation(EVL) has been adopted as a new treatment for acute hemorrhage from esophageal varices that ranks the highest mortality rate in upper gastrointestinal tract bleedings. This treatment method has good effects for the urgent treatment and eradication of varices from acute variceal bleeding in repeated sessions. We enrolled 34 patients with an acute or chronic variceal bleeding episode at the time of admission in this study from Apr. 8, 1992 to June. 2, 1994. Among 34 patients, there were 31 males and 3 females, at ages between 45-66(mean: 52 years). The incidence of symptoms on admission was 10 in tarry stool, 9 in hematemesis 8 in ascites, 4 in hepatic encephalopathy and 3 in nonspecific symptoms. Varices were eradicated or reduced to grade I in 30(88.2%) of the 34 patients by 4-25 bands (mean: 10.8 bands) in 1-7 EVL sessions(mean: 3.1 sessions). After EVL, there are complicated by active bleeding in 3 patients, dysphagia in 3 patienta and transient chest discomfort in 5 patients but subsided during 24 hours. These results indicated that EVL is a safe method for treatment of bleeding from esophageal varices.

BACKGROUND: The aim of this study was to retrospectively evaluate and analyze the brain magnetic resonance imaging (B-MRI) findings of patients with a favorable neurological outcome following cerebral performance category (CPC) after out-of-hospital cardiac arrest (OHCA) at single university hospital emergency center. METHODS: Patients with return of spontaneous circulation (> 24 h) after OHCA who were older than 16 years of age and who had been admitted to the emergency intensive care unit (EICU) for over a 57-month period between July 2007 and March 2012 and survived with a favorable neurological outcome were enrolled. B-MRI was taken after recovery of their mental status. RESULTS: Fifty-two patients among the 305 admitted patients had a good CPC, and 33 patients' B-MRI were analyzed (CPC 1: 26 patients, CPC 2: 7 patients). Among these, 18 (54.5%) patients had a normal finding on B-MRI. On the other hand, ischemia/infarction/microangiopathy compatible with hypoxic-ischemic encephalopathy (HIE) were found on various brain areas including subcortical white matter (7/13), cerebral cortex, central semiovlae, basal ganglia, putamen, periventricular white matter, and cerebellum. CONCLUSIONS: Survivors with a favorable neurological outcome from OHCA showed HIE on B-MRI, especially all of the patients with a CPC 2. More detail neurologic category including brain imaging would be needed to categorize patients with favorable outcome after OHCA.

Splenic anomalies are commonly associated with anomalies of cardiovascular system and of other organ systems. "Polysplenia" refers to the state in which the bulk of splenic tissue is divided into two and others more equal-sized splenic masses. We experienced a case of Polysplenia associated with complicated cardiovascular anomalies(Situs ambiguus, D-loop, normally related great arteries, interrupted inferior vena cave, bilateral superior vena cava, single atrium, common A-V canal, infundibular stenosis). We have presented this rare case and reviewed brief literatures.

PURPOSE: MRI is known to display the anatomy of the larynx in excellent detail with its remarkable soft tissue delineation and multiplanar imaging capability. We evaluate the accuracy of MRI in diagnosis and staging of laryngeal cancer MATERIALS AND METHODS: Sixteen cases with pathologically proved squamous cell carcinoma of the larynx were reviewed, retrospectively. The examination was performed with a 0.5 T superconductive MR system and C1 surface coil. Axial, sagittal and coronal plane with T1WI(TR/TE 450/20) and T2WI(TR/TE 18OO/80) were done. RESULTS: Eleven cases with glottic cancer(5 Tla, 3 Tlb, 1 T3 and 2 T4) and 5 cases with supraglottic cancer (1 T1, 1 T3 and 1 T4) were included. Cancer tissue showed intermediate signal intensity on TIWI and high signal intensity on T2Wl. Among 16 cases, 13 cases were correctly staged and 3 cases were overstaged due to edema caused by previous biopsy, partial volume averaging effect of abutted lesion, or surrounding inflammation. CONCLUSION: MRI is an useful modality for diagnosis of laryngeal cancer, especially in evaluation of paraglottic extention on coronal image and cartilage invasion.

The authors reviewed the clinical findings and treatment results of 12 cases of spinal meningeal cysts which were detected in MRI of low back patients. In these lesions, large cysts without CSF communication can compressed the nerve roots within spinal canal and it is difficult to confirm the cause of symptom whether it is originated from cysts or from associated spinal disorders. The terms and classifications of spinal meningeal cysts were very confusing. Among 12 cases, we excised 3 cases of large cysts with gluteal and perianal pains that were caused by compressed sacral nerve roots. All three cases were type 2 cyst (classified by Nabors) and located in sacral canal. In one case associated with isthmic spondylolisthesis, posterolateral fusion and pedicle screw fixations were combined with cyst excision. In other two cases, there were not any spinal pathologic findings that compressed sacral nerve roots except mild degenerative changes and intervertebral disc herniation in lower lumbar and sacral levels All 3 excised cases showed good prognosis in more than one year follow up. The other cases were treated conservatively for the associated spinal disorders.
