Résumé
Objective@#Body mass index (BMI) is a major determinant of N-terminal pro-brain natriuretic peptide (NT-proBNP). However, the relationship of BMI with pneumonia has not been entirely characterized. @*Methods@#Adult patients with pneumonia, who visited the emergency department from January 2017 to December 2019, were included. According to BMI, they were divided into two groups, including normal-weight and obesity groups. Data were retrospectively reviewed via the prospectively collected pneumonia registry and medical chart. NT-proBNP, BMI and pneumonia severity index (PSI) were determined for all subjects. The moderating effect between NT-proBNP and BMI was examined by entering interaction terms into the multivariable regression model predicting mortality. Using the area under the curve (AUC), the predictive performance of NT-proBNP was evaluated. @*Results@#Of 327 enrolled patients, 118 patients belonged to the obesity group. In a multivariable model including BMI, NT-proBNP was identified as an independent predictor of mortality. The AUC of the adjusted NT-proBNP including BMI, significantly increased the AUC of the adjusted NT-proBNP excluding BMI and tended to be superior to that of PSI. A positively significant BMI-by-NT-proBNP interaction for mortality was observed. NT-proBNP showed significant prognostic power in both BMI groups, but NT-proBNP of the obesity group had significantly higher AUC than that of the normalweight group. In the obesity group, the AUC of NT-proBNP tended to be higher than that of PSI. @*Conclusion@#BMI is a significant factor enhancing the prognostic power of NT-proBNP in pneumonia. The prognostic utility of NT-proBNP was significantly differed by BMI groups, which is more useful in the obesity group than the normalweight group.
Résumé
Objective@#N-terminal pro-B-type natriuretic peptide (NT-proBNP) is suggested as a prognostic biomarker for communityacquired pneumonia (CAP). However, its predictive value for an individual adult and elderly CAP patients has not been fully investigated. @*Methods@#Patients with CAP aged 18 years and older, who visited the emergency department (ED) from March 1, 2016 to March 31, 2019, were included in this study. Patients were divided into the adult group and the elderly group (age ≥70 years). Data was collected from the ED-based registry, and medical charts were retrospectively reviewed. The registry data included sociodemographic and past medical characteristics, as well as laboratory findings including NT-proBNP and C-reactive protein (CRP), Pneumonia Severity Index (PSI), and CURB65 (confusion, urea, respiratory rate, blood pressure, and aged 65 or more). The independent potential of NT-proBNP to predict mortality was assessed in both groups using multivariable logistic regression, and its predictive ability was evaluated in terms of performance (using areas under the curve [AUCs]) and goodness-of-fit (using the Bayesian information criterion [BIC]). @*Results@#Totally, 325 CAP patients were evaluated, of which 208 (64%) belonged to the elderly group. NT-proBNP was identified as an independent predictor of CAP mortality in elderly patients, but not in adult patients. Moreover, AUC of the NT-proBNP for mortality was comparable to AUC of the PSI, but was higher than that of the CURB65, in elderly CAP patients. Similarly, the NT-proBNP had a better overall fit (lower BIC value) compared to the CURB65, for mortality. Additionally, both AUC and overall fit of the NT-proBNP for mortality were significantly superior to values obtained for CRP. @*Conclusion@#For elderly CAP patients in the ED, the NT-proBNP is an independent and useful predictor of mortality.

Purpose@#The aims of the present study were twofold. First, the research investigated the effect of an individual’s risk factors and the prevalence of psychotropic drugs on QTc prolongation, TdP (torsades de pointes), and death. Second, the study compared the risk scoring systems (the Mayo Pro-QT risk score and the Tisadale risk score) on QTc prolongation. @*Methods@#The medical records of intoxicated patients who visited the emergency department between March 2010 and February 2019 were reviewed retrospectively. Among 733 patients, the present study included 426 psychotropic drug-intoxicated patients.The patients were categorized according to the QTc value. The known risk factors of QTc prolongation were examined, and the Mayo Pro-QT risk score and the Tisadale risk score were calculated. The analysis was performed using multiple logistic regression, Spearman correlation, and ROC (receiver operating characteristic). @*Results@#The numbers in the mild to moderate group (male: 470≤QTc<500 ms, female: 480≤QTc<500 ms) and severe group (QTc≥500 ms or increase of QTc at least 60ms from baseline, both sex) were 68 and 95, respectively. TdP did not occur, and the only cause of death was aspiration pneumonia. The statically significant risk factors were multidrug intoxications of TCA (tricyclic antidepressant), atypical antipsychotics, an atypical antidepressant, panic disorder, and hypokalemia. The Tisadale risk score was larger than the Mayo Pro-QT risk score. @*Conclusion@#Multiple psychotropic drugs intoxication (TCA, an atypical antidepressant, and atypical antipsychotics), panic disorder, and hypokalemia have been proven to be the main risk factors of QTc prolongation, which require enhanced attention. The present study showed that the Tisadale score had a stronger correlation and predictive accuracy for QTc prolongation than the Mayo Pro-QT score. As a result, the Tisadale risk score is a crucial assessment tool for psychotropic drug-intoxicated patients in a clinical setting.
Résumé
Purpose@#Agent Orange (AO) is a herbicide and defoliant used by the United States and its military allies during the Vietnam War. Pneumonia is a common cause of death among Vietnam veterans in our hospital. There have been no previous studies researching any association between AO exposure and the prognosis for pneumonia. The primary objective of this study was to investigate associations between AO exposure and 30-day mortality due to pneumonia. The secondary objective was to examine the clinical factors associated with therapeutic outcomes in veterans with pneumonia, and to assess the prevalence of combined diseases in AO-exposed veterans. @*Methods@#This study retrospectively included veteran patients diagnosed with pneumonia in the emergency department and hospitalized between February 2014 and March 2018. The enrolled patients were grouped according to their defoliant exposure history, and the clinical information of defoliant-exposed and non-defoliant-exposed groups were compared. Patients were divided according to 30-day mortality, and significant factors influencing mortality were evaluated by using univariate analysis and multivariate analysis. The final multivariate model revealed the effect of AO exposure on therapeutic outcomes of pneumonia. @*Results@#A total of 1006 patients were analyzed. Of these, 276 patients had a history of AO exposure, whereas 730 patients had not been exposed. Factors positively associated with 30-day mortality were malignancy, respiratory rate, blood urea nitrogen, and albumin which was negatively associated with mortality. @*Conclusion@#Exposure to defoliant is not associated with 30-day mortality in patients with pneumonia. However, veterans with defoliant exposure are associated with a high prevalence of diabetes mellitus, hypertension, cerebrovascular accident, malignancy, and chronic kidney disease.

OBJECTIVE: This study was conducted to evaluate the validity of the International Classification of Diseases, 10th revision (ICD-10) codes for identifying patients who suffered out-of-hospital cardiac arrest (OHCA). METHODS: Consecutive data pertaining to adult patients who suffered OHCA or received ICD-10 codes for cardiac arrest were collected. Patient characteristics and clinical data during the period from January 2015 to December 2016 were obtained. The sensitivity and positive predictive value (PPV) of each code for identifying OHCA were calculated and an optimal algorithm using diagnostic and procedure codes to detect OHCA patients was selected. The kappa coefficient was calculated to examine the agreement between algorithm-detected cases and true OHCA patients. RESULTS: A total of 397 patients were included in this study. The single use of ICD-10 codes was an insensitive method for identifying OHCA patients. Combination of diagnostic codes and procedure codes showed a good sensitivity (98.6%) and PPV (94.8%) for identifying OHCA patients. The agreement between the optimal algorithm and true OHCA was excellent (κ=0.970). CONCLUSION: Using ICD-10 codes for identifying OHCA patients is an insensitive method. The combination of ICD-10 codes and procedure codes can be an alternative search method.

PURPOSE: The purpose of this study was to evaluate the predictive value of the measured factors that can be used in an emergency department to assess patients with blow-out fractures (BOFs) who are expected to undergo surgical management. METHODS: This study was conducted on patients with BOFs who attended an emergency department in a tertiary teaching hospital from December 2013 to November 2016. The medical records and radiology findings, such as facial computed tomography (CT), were reviewed retrospectively. The depth of floor displacement (DFD) and cranial-caudal dimension (CCD), which were measured using facial CT, were evaluated to determine the power of the CT parameters as predictors expecting surgical management in BOF patients. Statistical analysis was conducted with SPSS statistics ver. 23.0. RESULTS: The final 44 BOF patients were included in the study. Among them, 21 patients had undergone surgery. From this study, using a threshold DFD value of 0.5 cm, the accuracy of DFD was 86.36%, and the sensitivity and specificity in predicting surgery in BOF patients was 100% and 73.91%, respectively. Using a threshold CCD value of 0.4 cm, the accuracy of CCD was 88.64%, and the sensitivity and specificity in predicting surgery in BOF patients was 100% and 78.26%, respectively. CONCLUSION: With the aid of DFD and CCD, which was measured from facial CT, BOF patients who may require surgical management can be detected easily and more promptly by emergency physicians in emergency settings.

PURPOSE: This study examined the availability of the age shock index in an assessment of high risk patients with acute cholecystitis in an emergency department. METHODS: Consecutive data of patients who presented to the emergency department with acute cholecystitis during the period, January 2012 and March 2017, were reviewed retrospectively. Univariate and multivariate analyses were performed to determine the relationship between the severity of acute cholecystitis and the clinical factors. RESULTS: A total of 242 patients with acute cholecystitis were included in this study. From univariate analyses, age, Murphy's sign, symptom duration, heart rate, respiratory rate, age shock index, hypertension, diabetes, leukocytes, C-reactive protein and blood urea nitrogen were found to be related to the severity of acute cholecystitis. From multivariate analysis, the symptom duration (OR, 4.271; 95% CI, 2.672-6.827), respiratory rate (OR, 1.482; 95% CI, 1.189-1.847), age shock index (OR, 1.609; 95% CI, 1.060-2.442, 10-point interval), leukocytes (OR, 1.283; 95% CI, 1.156-1.424), and diabetes (OR, 4.590; 95% CI, 1.507-13.976) had a positive relationship with the severity of acute cholecystitis. CONCLUSION: The age shock index, which is calculated easily using the patient's age, heart rate, and systolic blood pressure, can be a predicting factor of severe acute cholecystitis in an emergency department.

Toxic shock syndrome (TSS) is a rare but life-threatening illness that is mainly caused by toxigenic strains of Staphylococcus aureus. Although TSS is classically known to be associated with tampon use, the number of TSS cases with non-menstrual causes such as skin and soft tissue infection has been increasing. Tattooing can result in several complications such as localized and systemic infections, inflammatory skin eruptions and neoplasms. We recently experienced a 26-year-old man diagnosed with typical TSS following tattooing. He complained of fever, chills and erythematous rash at tattoo site. Subsequently, the patient developed sign of shock. The skin cultures on the tattoo site were positive for methicillin-sensitive Staphylococcus aureus. The patient was successfully treated with vasopressor infusion and intravenous antibiotics and was discharged without complications. On discharge from the hospital 7 days later, desquamations on the tattoo site, fingers and toes were observed.

PURPOSE: Chest injuries in multiple trauma patients are major predisposing factor for increased length of stay in intensive care unit, prolonged mechanical ventilator, and respiratory complications such as pneumonia. The aim of this study is the evaluation of lung injury score as a risk factor for prolonged management in intensive care unit (ICU). METHODS: Between June to August in 2011, 46 patients admitted to shock and trauma center in our hospital and 24 patients had associated chest damage without traumatic brain injury. Retrospectively, we calculated injury severity score (ISS), lung injury score, and the number of fractured ribs and performed nonparametric correlation analysis with length of stay in ICU and mechanical ventilator support. RESULTS: Calculated lung injury score(<48 hours) was median 1(0-3) and ISS was median 30(8-38) in study population. They had median 2(0-14) fractured ribs. There were 2 bilateral fractures and 2 flail chest. Ventilator support was needed in 11(45.8%) of them for median 39 hours(6-166). The ISS of ventilator support group was median 34(24-34) and lung injury score was median 1.7(1.3-2.5). Tracheostomy was performed in one patient and it was only complicated case and ICU stay days was median 9(4-16). In correlation analysis, Lung injury score and ISS were significant with the length of stay in ICU but the number of fractured ribs and lung injury score were predicting factors for prolonged mechanical ventilator support. CONCLUSION: Lung injury score could be a possible prognostic factor for the prediction of increased length of stay in ICU and need for mechanical ventilator support.

PURPOSE: The aim of this study was to evaluate the quality of the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency intensive care unit (ICU) in consultation with intervention radiologists and surgeons. METHODS: This was a retrospective observational study conducted in an emergency ICU of a tertiary referral hospital. We enrolled consecutive patients who had been admitted to our emergency ICU with major trauma from March 2007 to September 2010. We collected data with respect to demographic findings, mechanisms of injury, the trauma and injury severity score (TRISS), emergency surgery, angiographic intervention, and 6-month mortality. Then, we compared the observed and predicted survivals of the patients. The Hosmer-Lemeshow test and calibration plots by using 10 groups, one for each decile, of predicted mortality were used to evaluate the fitness of TRISS. P-values of greater than 0.05 represent a fair calibration. RESULTS: Among 116 patients, 12 (10.34%) were dead within 6 months after admission to the ICU, and 29 (25.00%) and 38 (32.80%) patients received emergency surgery and angiographic intervention, respectively. The mean injury severity score and revised trauma score were 36.97+/-17.73 and 7.84+/-6.75, respectively. The observed survival and the predicted survival of the TRISS were 89.66% (95% confidence interval [CI]: 84.03~95.28%) and 69.85% (95% CI: 63.80~75.91%), respectively. The calibration plots showed that the observed survival of our patients was consistently higher than the predicted survival of the TRISS (p<0.001). CONCLUSION: The observed survival for the trauma care system of our hospital, in which emergency physicians care for major trauma patients in the emergency ICU in consultation with intervention radiologists and surgeons, was higher than the predicted survival of the TRISS.

PURPOSE: To investigate whether or not low clinical serum selenium levels are associated with survival prognosis for septic shock patients. METHODS: This was a prospective, observational study conducted in an emergency Intensive Care Unit (ICU) at a tertiary referral hospital in Korea. We enrolled consecutive, septic shock patients who were admitted to the ICU from March 2008 to February 2010. We collected patient data with respect to demographics, infection sites, pathogens, serum lactate levels, central venous oxygen saturations, and serum selenium levels at the time of ICU admission. We also collected data with respect to 6-hour early goal achievement, Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Sequential Organ Failure Assessment (SOFA) score, mechanical ventilator or renal replacement therapy application, and steroid administration. Using a 28-day mortality criterion, enrolled patients were divided into two groups: survivors and non-survivors. Resulting data was compared between the two groups. RESULTS: Among 115 patients, 81 were the survivors and 34 were non-survivors. Lower serum selenium levels (odds ratio [OR]=0.945, 95% confidence intervals [CI], 0.908-0.984, p=0.006) and higher APACHE II scores (OR=1.096, 95% CI, 1.006-1.195, p=0.036) were independently associated with 28-day patient mortality results. The cutoff serum selenium level was 47.5 microg/L (sensitivity 0.80, specificity 0.71, area under curve=0.745) for 28-day mortality. CONCLUSION: Serum selenium levels of 47.5 microg/L or lower are associated with 28-day mortality for septic shock patients.

BACKGROUND: The resistance rate of Escherichia coli (E.coli) against ciprofloxacin is reported as high as 30% in Korea. The purpose of this study was to evaluate the clinical outcome of two empirical antibiotics, ciprofloxacin and cefotaxime, in patients with acute pyelonephritis (APN). MATERIAL AND METHODS: We retrospectively reviewed medical records of APN patients who were prescribed with ciprofloxacin or cefotaxime as empirical antibiotics from November 2004 and June 2006. The Successful treatment (ST) was defined as the condition that a patient maintained body temperature below 37.7degrees C for more than 48 hours after treatment. RESULTS: A total of 64 patients were enrolled (31 in the ciprofloxacin and 33 in the cefotaxime group). Average age was 58.9 (+/-15.8) years and 58 (90.6%) patients were women. Comparing WBC count and CRP level before treatment with those after 48 hours of treatment, significant improvements were found only in the cefotaxime group. After 48 hours, the cefotaxime group had more patients with ST, but the difference was not significant [19 (58%) vs. 12 (39%), P=0.131]. After 72 and 120 hours, the cefotaxime group showed significantly higher ST rate than the ciprofloxacine group [72 hours; 30 (91%) vs. 19 (61%), P=0.016 and 120 hours; 32 (97%) vs. 23 (74%), P=0.009]. Even after adjusting demographic factors, the cefotaxime group showed higher ST rate. CONCLUSION: Cefotaxime can be considered as a better option for empirical treatment for APN in aspects of improvement of acute phase reactants and clinical cure, especially in endemic area of highly resistant E. coli.

PURPOSE: N-acetylcysteine (NAC) has been known to have protective effects on the prevention of radiocontrast induced nephropathy (RCIN) in chronic renal failure (CRF). We investigated the effects of NAC in acute renal failure (ARF). METHODS: From January to June 2006, we retrospectively enrolled patients with ARF who were checked with contrast computed tomography (CT) at an emergency department. We divided patients into the NAC group and the control group. We compared baseline demographic characteristics, underlying diseases, infused fluid volume, blood urea nitrogen (BUN), and serum creatinine (Cr) level before and after CT scan. ARF was defined as serum Cr>1.5. mg/dL. RCIN was defined as an increase in serum Cr level of at least 0.5 mg/dL or 25% 48 hours after CT. RESULTS: Of a total 106 cases, 23 patients were the NAC group and 83 were the control group. There were no significant differences in baseline findings including underlying disease, cause of ARF and serum Cr level. The volume of infused fluid before and after CT were not different between the two groups (before; p=0.183 after; p=0.149). After CT scan, BUN and serum Cr level were decreased without statistical significance in both groups (NAC vs control group: BUN; 21.0+/-12.9 vs 20.5+/-14.2 p=0.863 Cr; 1.3+/-0.5 vs 1.4+/-0.5 p=0.451). RCIN developed in total 3 cases, 2 cases in the NAC group and 1 in the control group (p=0.524) and one of the NAC group performed hemodialysis. CONCLUSION: In case of patients with ARF, there was no protective effect of NAC on RCIN.

BACKGROUND AND PURPOSE: Congenital nystagmus (CN) is an ocular oscillation that usually manifests during early infancy. Typical features of CN include bilateral, conjugate, uniplanar, and usually horizontal eye movements, a null position, increased oscillation during fixation, and decreased amplitude during convergence. Our purposes were description and analysis of clinical and oculomotor findings of patients with X-linked familial CN. METHODS: We describe the clinical and oculographic features of five patients from three families with X-linked CN. Three-dimensional video-oculography disclosed various patterns of CN and variable degrees of gaze-holding deficits and visual impairments. RESULTS: The features of CN varied even in patients from the same family. Head tilt, strabismus, reversal of optokinetic nystagmus, and impairments of the vestibulo-ocular reflex, smooth pursuits, and saccades were frequent findings. CONCLUSIONS: The intra- and interfamilial diversities imply that heredity plays a secondary role in determining the clinical phenotypes and waveforms of CN.
