PURPOSE: Plasma neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker that shows correlation with the severity of acute infection and acute kidney injury (AKI). This study was conducted in order to determine the predictive value of NGAL in the emergency department for predicting the severity of acute pyelonephritis. METHODS: A retrospective study was conducted between October 2012 and May 2013. A total of 46 patients diagnosed with acute pyelonephritis were enrolled in this study. Plasma NGAL was measured upon admission to the hospital and clinical and laboratory data, CT were collected. Based on these data, we classified our patients according to two groups (high NGAL group: NGAL > or =400 ng/mL vs low NGAL group: NGAL <400 ng/mL) and we evaluated the correlation between clinical data, laboratory data, and CT. RESULTS: Among the 46 patients, there were 45 female patients and the mean age was 59.0+/-20.4 years. Statistically significant differences in CT grades, hospital stay, SIRS, and shock were observed between the NGAL groups. The area under the ROC curve for CT severity by NGAL was 0.890(95% CI, 0.796-0.985), which was better than CRP and MDRD GFR. NGAL levels showed correlation with CRP (r=0.508; p<0.001) and MDRD GFR (r=-0.766, p<0.001). CONCLUSION: NGAL is a useful specific biomarker predicting severity of acute pyelonephritis.

Procedural sedation and analgesia (below PSA), which is used for induction of appropriate sedation and elimination of pain during many procedures, is particularly essential for children. Many other countries have pediatric PSA guidelines. PSA guidelines are also needed in Korea. We have developed pediatric PSA guidelines for Korea by reference review of pediatric PSA for standard and safe PSA practice in Korea. Pharmacologic and non-pharmacologic methods could be used for performance of ideal pediatric PSA. Pre sedation phase included assessment of patients, with accompanying personnel who have adequate knowledge and experience, and informed consent. For sedation phase, the route of medication should be determined, along with monitoring of patients and evaluation of the depth of sedation. This phase also included writing all of the PSA process, adverse events, and intervention. Considering the pain of the procedures, the time of procedures, necessity for immobilization, and characteristics of PSA medication, we decided on the PSA method. Procedures were categorized into three types according to the level of pain, anxiety, and immobilization. The first type was radiologic imaging, which requires immobilization. The second type of procedure involves a high level of anxiety and a low level of pain, such as simple suturing and lumbar puncture. The third type of procedure involves a high level of anxiety and a high level of pain, such as reduction of fracture and dislocation. After performance of the procedure, patients must be observed and monitored at a location where oxygen and airway management can be applied until they reach full recovery. Discharge information should be provided to competent parents. The main characteristics of Korean guidelines for pediatric PSA were as follows: 1. We emphasized assessment and monitoring of patients during and after PSA. 2. We suggested selection of medication by categorization of procedures according to the level of pain and anxiety. 3. We suggest that PSA be performed by two healthcare personnel; one should have adequate knowledge and experience in performance of PSA. More equipment, locations, and specialized personnel are needed for conduct of safe pediatric PSA practice in Korea.

PURPOSE: Electrical injuries may cause many psychiatric complications such as depression, acute stress disorder, post-traumatic stress disorder (PTSD), etc. The purpose is to search the incidence of psychiatric complications in electrical injury and to compare its associated risk factors with other burn and trauma. METHODS: We reviewed the medical records of 709 electrically injured patients who were admitted to Hanil General Hospital from 2002 to 2007. Psychiatric complications were defined as depression, acute stress disorder and PTSD according to DSM-IV. We sorted the medical records into demographics, hospitalization, electrical voltage, injured type, extent or site of burn and type of amputation. RESULTS: Total incidence of psychiatric complications was 27.5% (Depression; 15.8%, acute stress disorder or PTSD; 17.6%). High voltage injured patients had psychiatric complications 2.38 times higher than low voltage. Incidence of psychiatric complications were 1.83 times in 6~10% of BSA, 2.01 times in 11~20% and 2.41 times in 21~30% higher than in 0~5% of BSA. If the site of burn included face, psychiatric complications occurred 1.96 times more than other sites. Patients with history of minor and major amputation showed 2.39 and 7.70 times incidence of psychiatric complications, respectively. CONCLUSION: The risk factors of psychiatric complications were high voltage electrical injury, facial burn, extent of burn and history of amputation. If the patients have risk factors, earlier psychiatric consultation may help to manage the psychiatric complications of electrical injury.

PURPOSE: High voltage electrical injury mainly occurs in the industrial field. It can cause serious complications and sequelae that lead to high social and economic costs. We investigated the causes of this to try to help prevent these injuries. METHODS: We reviewed 128 patients who incurred high voltage electrical injury during a 3-years period from Jan. 1, 2006 to Dec. 31, 2008. We performed a retrospective analysis of the medical records to review the epidemiology. We also performed a survey by telephone. The survey questions addressed the following: the duration of work, wearing safety equipment, the reason for working without safety equipment, did they receive safety education, was the safety education adequate, recognition of a high tension wire before working and did they understand the effect of high voltage on the human body. RESULTS: The safety education was relatively carried out well. But most patients did not wear safety equipment even though they knew they had to wear it (92%). The major reason was discomfort of wear it (72%). The hand was the most common injury site (80%). Most injuries occurred with 22,900 volt or less (92%). In spite of safety education, many patients were unaware of the effects of electrical injury on their body. CONCLUSION: Strengthened safety education can play a significant role in preventing high voltage electrical injury. At this point, the doctors who are experienced in treating high voltage electrical injury must actively participate in this safety education. We suggest that handy safety equipment can lessen the incidence of high voltage electrical injury. It is essential to develop a handy safety glove for 22,900V with considering that the hand was the most common injury site and the most frequent voltage for injury was 22,900 volt or less.

PURPOSE: High voltage electrical injuries can cause many complications of central nervous system. We tried to define the indication range of brain CT (computerized tomography) in high voltage electrical injuries. METHODS: We performed a retrospective analysis of 51 high voltage electrical injured patients who were confirmed by brain CT, they had visited our emergency department from January 2005 to December 2007. All patients were classified by brain CT findings, presences of combined injuries and neurologic symptoms. RESULTS: 48 patients were confirmed normal in brain CT findings. 3 patients had brain lesions that were associated with secondary trauma. There was no abnormal CT finding in the 23 patients who did not have loss of consciousness, falling and combined injuries. CONCLUSION: If patient with electrical injury did not have neurologic symptoms or sufficient mechanical force, brain CT is not recommended. The results of this study may help emergency physicians to avoid unnecessary brain CT examination in the emergency triage to a high voltage electrical injury patients.

PURPOSE: Cerebral ischemia lead to neuronal damage in a specific area of the brain of both rodents and humans. After ischemia, the pyramidal cells in area CA1 of the hippocampus are particularly sensitive, but death of these pyramidal cells is delayed to at least 3~4 days after the transient cerebral ischemia. Induction of HSP70 has been mainly observed in resistant areas, so a protective effect has been proposed for HSP70. The presence of HSP70 is a good indicator of the general pathophysiologic stress response to ischemia, but not necessarily a marker for neuronal survival. METHODS: Fisher rats (344) were used in the present experiments. Mild Transient ischemia was induced by using two common methods, carotid artery occlusion and reperfusion. For immunostaining, brain tissues were prepared following intracranial perfusion, and frozen sections were cut on a crystal. Section were incubated with mouse monoclonal antibodies by using a free-float method. Hippocampal tissues at the indicated times were prepared for Western blot analysis. For the determination of the protein levels of HSP70, tissue extracts were subjected to ECL Western blot analysis using primary antibodies. The result from Western blotting was expressed numerically through an image analysis. RESULTS: HSP70 expression markedly increased in 2-day group of transient mild cerebral ischemia after reperfusion. HSP70-positive cells were observed in the cerebral cortex, the striata terminalis, and the hippocampus 2 days after the onset of ischemia. In preconditioned ischemia, no ischemic cell death due to necrosis and apoptosis was noted. CONCLUSION: Preconditioning is induced by mild transient cerebral ischemia, and that is a potent stimulator of HSP70 gene expression.

PURPOSE: When using the emergency room of a tertiary hospital, both patients and their relatives or friends sometimes experience dissatisfaction and complain. Patient satisfaction deserves attention not only because it is an intrinsically worthy goal but also because it is a potentially significant mediator for promoting health and well-being. This study aims to identify patient's official complaints and to improve the quality of care in the Emergency Department (ED). METHODS: We investigated retrospectively 144 official complaints of visitors in 4 tertiary university hospital emergency centers between January 1, 2001, and December 31, 2003. RESULTS: Among those 144 official complaints from the 4 hospital emergency centers were 116 appropriate complaints, as determined by the inclusion criteria, and 212 detailed descriptions of dissatisfaction. The seven major categories of dissatisfactions were analyzed: rudeness or lack of kindness, delayed waiting time, insufficient explanation of patient condition, distrust of treatment, absence of a specialist, poor emergency-department environment, and high treatment fee. CONCLUSIONS: Dissatisfaction related to the lack of kindness was the most common problem in all four university hospital emergency centers. The next most important problem was the delayed time or distrust of treatment. The concrete causes of the complaints varied with the hospital. To improve the quality of care for patients in the ED, the hospital staff should be more attentive and kind and should explain the patient's condition in more detail. Reducing the waiting time is also important.

Aortic dissection during pregnancy is rare, but is life-threatening event for both the mother and the fetus. Depending on the type of dissection, surgical or medical treatment can be performed. The attempt of cesarean section delivery is determined by gestational age. We experienced a case of aortic dissection at 32 weeks of gestation. The type of dissection was DeBakey type III and was managed medically. Under general anesthesia, cesarean delivery was performed at 35 week's gestation. In pregnant patients complaining of chest or abdominal pain not related to labor, the suspicion of aortic dissection is important for prompt diagnosis and better prognosis.
