RESUMEN
PURPOSE: Kawasaki disease (KD) is an acute, self-limited, febrile disease. For cases of KD in which the first symptom is cervical lymphadenopathy (node-first presentations of KD, NFKD), it is frequently misdiagnosed as bacterial cervical lymphadenitis (BCL). Therefore, we evaluated the usefulness of N-terminal pro-brain natriuretic peptide (NT-proBNP) to differentiate between NFKD and BCL. METHODS: This is a retrospective, observational study. Patients were divided into three groups, KD as 1st diagnosis, NFKD, and BCL. The laboratory and demographic data, intravenous immunoglobulin (IVIG) administration time and total febrile duration, length of hospital stay, and number of coronary artery complications were then compared for each group. RESULTS: A total of 451 patients were diagnosed as KD and 45 patients as BCL. Of the 451 KD patients, 417 (92.5%) were KD as 1st diagnosis, and 34 (7.5%) were NFKD. White blood cell count, absolute neutrophil count, C-reactive protein, erythrocyte sedimentation rate, and NT-proBNP differed significantly between NFKD and BCL. Variables that differed significantly were analyzed using a receiver operating characteristic curve, which revealed that NT-proBNP had the largest area under curve (0.944). Additionally, IVIG administration time, total febrile duration and length of hospital stay differed between KD as 1st diagnosis and NFKD. CONCLUSION: It is difficult to differentiate NFKD from BCL, so proper treatment and length of hospital stay were delayed. NT-proBNP is very useful for differentiating NFKD and BCL. Therefore, in cases of BCL with a long febrile period without reacting general treatments, the NT-proBNP test can be considered.

PURPOSE: Diabetic ketoacidosis (DKA) is a fatal complication caused by unregulated diabetes. Lactate is used as a prognostic indicator for a range of serious illnesses and its level is higher in DKA patients. This study examined the utility of lactate and lactate clearance measurements at an emergency department for predicting the prognosis of DKA patients. METHODS: This was a retrospective, observational study of patients with DKA presenting to the emergency department of an urban and rural tertiary hospital between January, 2013 and December, 2016. The demographic and laboratory data were collected through a chart review. RESULTS: Seventy-six patients with DKA were included. Of these 76 patients, 46 (56.8%) had lactic acidosis (lactate >2.5 mmol/L) and 24 (29.6%) had a high lactate level (>4 mmol/L). Lactate and lactate clearance showed a significant difference in terms of the intensive care unit length of stay and mortality. CONCLUSION: Lactate and lactate clearance measurements in DKA patients are favorable and significant prognostic factors. In DKA patients, serial measurements of lactate should be considered.

Gastric outlet obstruction (GOO) is a disease that causes pyloric canal or duodenal atresia by various etiologies. It is mainly caused by malignancy or peptic ulcer and rarely caused by corrosive injury, gastric polyp, pyloric stenosis, bezoar, or biliary stone. We report a rare case of GOO due to unreported etiology. A 74-year-old male patient with medical history of hypertension, diabetes mellitus, and stroke came to the emergency medical center with a chief complaint of acute stomachache. On abdominal computed tomography, it was diagnosed as GOO due to gall bladder distension from acute cholecystitis. During conservative treatment and antibiotics administration, gastrofibroscopy and magnetic resonance cholangiopancreatography was performed to determine other etiologies; however, the final diagnosis was made as acute cholecystitis. After laparoscopic cholecystectomy, he was discharged without specific complications. On a pathology examination postoperation, there was no specific diagnosis, except for acute cholecystitis. Gastric outlet obstruction is caused by various etiologies, with the course of treatment being dependent on the specific etiology. We report a rare case of GOO caused by gall bladder distension due to acute cholecystitis. Various etiologies should be considered carefully to include even the rare etiologies for choosing the correct treatment.

PURPOSE: In this single-center, prospective, randomized, cross-over study, we compared the efficiency of oxygen supply between OxyMask and non-rebreather mask (NRM), depending on the position of the mask. METHODS: Either OxyMask or NRM was applied to 33 healthy volunteers, in a random manner, on the upper (that 1 cm upper to it), lower (that 1 cm inferior to it) and lateral malposition (that 1 cm lateral to it). After a 3-minute oxygenation, at a flow rate of 15 L/min, we measured the fractional expired oxygen concentration (F(E)O₂), fractional expired carbon dioxide concentration (F(E)CO₂), and visual analogue scale (VAS) scores for the degree-of-wearing sensation. RESULTS: OxyMask showed a lower level of F(E)O₂ as compared with NRM in all positions. Moreover, OxyMask showed no significant difference between F(E)O₂ and the position of the mask. However, NRM showed a significantly lower F(E)O₂ in the upper and lateral malposition. F(E)CO₂ had no significant difference with the types and position of the mask. The mean VAS scores for the degree-of-wearing sensation were 2.2±1.5 in the OxyMask and 4.3±1.5 in the NRM (p<0.001). CONCLUSION: OxyMask may offer greater benefit in maintaining the concentration of supplied oxygen and provide greater comfort than NRM in patients with difficulty applying the mask on an adequate location and maintaining the seal.

PURPOSE: Glufosinate-containing herbicides intoxication causes mild to severe complication, depending on patients' factors. However, it is not clearly known whether there are factors affecting glufosinate-containing herbicides intoxicated patients who develop complications. Thus, we sought to identify independent factors comparing the complicated group with the non-complicated group and to predict which patients will develop subsequent medical complication. METHODS: The medical records of patients with exposure to Glufosinate-containing herbicides at a tertiary academic university hospital in Korea from January 2012 to April 2015 were reviewed retrospectively. Demographic and clinical data of 75 patients were then analyzed by univariate and multivariate stepwise logistic regression analyses to identify potential predictors of significant complications following acute Glufosinate-containing herbicides poisoning for comparison of complicated patients with non-complicated patients. RESULTS: Of 75 patients, 44 (58.6%) had medical complications and 6 (8%) were dead. Neurologic complications (n=26, 35%) were the most common including seizure (n=18), delirium tremens (n=5), and amnesia (n=4). The results of univariate analysis showed that an advanced age (>60 years old), higher ingested amount of the herbicide (>100 mL), vomiting at arrival, medical history of hypertension, metabolic acidosis, and systemic inflammatory response score (SIRS)> or =2 were significant factors. However, the results of multivariate analysis showed that an advanced age (p60 years, and amount ingested>100 mL were significant predictive factors for significant medical complications in patients with Glufosinate-containing herbicides poisoning.

PURPOSE: The aim of this study was to evaluate the sensitivity and specificity of ultrasonography of suspected ileocolic intussusception performed by emergency medicine (EM) residents who participated in a 2-hour focused ultrasound training program for intussusception. METHODS: This was a 16-month retrospective, observational study. Pediatric patients with suspected ileocolic intussusception who underwent ultrasound performed by second or third year EM residents were included in the study. The gold standard was a diagnostic work-up performed by a radiologist or clinical follow-up, compared with the results of ultrasonography performed by EM residents. RESULTS: A total of 38 patients were enrolled. The sensitivity of ultrasound performed by emergency medicine residents for prediction of ileocolic intussusception was 92.86%(66.13% to 99.82%), the specificity was 91.67%(73.00% to 98.97%), the positive likelihood ratio was 11.14(2.93 to 42.34), and the negative likelihood ratio was 0.08(0.01 to 0.52). CONCLUSION: Emergency residents can identify ileocolic intussusceptions with only minimal training, which could substitute for ultrasonography performed by radiologists when they are not immediately available.

PURPOSE: The aim of this study was to analyze factors affecting success of endotracheal intubation (ETI) in emergency department (ED) patients, and to investigate usefulness of expected difficult direct laryngoscopy for expectation of a bad Glidescope(R) view. METHODS: ETI data using Glidescope(R) were collected at two EDs over a period of 64 months. We accessed intubator's training level, expected difficulty with laryngoscopy, method, and glottis exposure grade. Based on these variables, we analyzed the intubation success rates. And we examined the correlation between glottis exposure grade using Glidescope(R) and factors for expectation of difficult direct laryngoscopy. RESULTS: A total of 613 ETIs attempts using Glidecope(R) were recorded. The overall success rate was 83.4%. In logistic regression analysis, expected difficult laryngoscopy, intubator's training level, and glottic exposure grade were independent predictive factors for successful ETI using Glidescope(R). The Cormack-Lehane grade I via Glidescope(R) was observed in 89.1% of total ETI attempts. In subgroup analysis, bad glottis exposure status showed a significantly low success rate irrespective of intubator's training level. Among the predicting factors for difficult laryngoscopy, morbid obesity, limited neck extension, and limited mouth opening showed an association with the degree of glottic exposure via Glidescope(R). CONCLUSION: The glottic exposure grade was the most important factor related to successful ETI using Glidescope(R). Morbid obesity, limited neck extension, and limited mouth opening showed a significant association with bad glottis exposure under Glidescope(R), Therefore, we need to identify these findings. Even if in good glottis view, junior physicians showed a lower rate of ETI success using Glidescope, therefore, measurements to improve the ability of junior physicians should be implemented.

PURPOSE: Although Pokeweed intoxication is relatively less severe, thereis little data onthe clinical presentation ofPokeweed intoxication in Korea. This study examined the clinical aspectsto providebasic data for evaluating Pokeweed intoxication. METHODS: A retrospective study by a chart review was performedon 19 patients who ingested Pokeweed and presented to anacademic emergency department with an annual census of 40,000 between March 2012 and May 2012. RESULTS: Nineteen patients were identified. All patients wereintoxicated unintentionally. The most common symptoms were vomiting with diarrhea and abdominal pain. The onset time varied, but occurs 30 minutes to 5 hours post ingestion of Pokeweed. All patients were discharged without fatal complications. CONCLUSION: Compared to previous reports, mostpokeweed poisoning patients complain of gastrointestinal symptoms. Supportive care is the mainstay of the management of pokeweed intoxication. All symptoms were resolved over a 24 to 48 hour period.

PURPOSE: It is not always easy to determine the existence of tendon injuries when it comes to patients with finger lacerations. Thus, we tried to find the difference in effectiveness and in compliance of patients when we employed two different types of diagnosis, conventional gross confirmation and ultrasonographic confirmation. METHODS: From December 2009 to March 2010, we enrolled 14 patients with finger tendon injury at Soonchunhyang University Cheonan Hospital. The median age of the patients was 35.9+/-14.4, and the ratio of females to males was 1:2.5 We evaluated the compliance of each patient by measuring four different categories (level of cooperativeness in showing their wound and in following the instructions, level of movement of their fingers during the diagnosis and total number of attempts to diagnose) by using a score from 1 to 3 for each category, for a total possible score of 12 for each patient. We also measured the painfulness of each patient by using a score of 1 to 10 and the time required for each diagnosis. RESULTS: The levels of patients' compliance was 8.9+/-2.1 when diagnosed with gross confirmation and 9.8+/-2.1 when diagnosed with ultrasonographic confirmation (p value=0.042). The pain score of the patients was 3.7+/-1.7 with gross confirmation and 2.9+/-1.2 with ultrasonographic confirmation (p value=0.020). The median duration of time in each test was 6.7+/-4.8 minutes with gross confirmation and 10.5+/-4.2 minutes with ultrasonography (p value=0.006). CONCLUSION: Comparing gross confirmation and ultrasonographic confirmation, gross confirmation is a better method than ultrasonography because of time efficiency. However, ultrasonographic confirmation has advantages over gross confirmation in pain scale and better compliance of patients. Emergency physicians generally employ gross confirmation rather than ultrasonography in determining the existence of tendon injury in patients. In patients with finger lacerations without bone injury, ultrasonography can be considered as a secondary diagnostic tool, especially when patients have much pain.

BACKGROUND/AIMS: Endoscopic retrograde cholangiopancreatography (ERCP) is difficult to perform in patients with a Billroth II anastomosis due to the anatomical alterations. This study evaluated retrospectively the efficacy and safety of endoscopic balloon dilatation after a partial infundibulotomy with a needle knife in patients who had undergone a Billroth II operation. METHODS: Between January 1, 2004 and December 31, 2005, 11 patients, who had undergone a prior Billroth II gastrectomy, underwent ERCP because of a suspicion of pancreatobiliary diseases. Infundibulotomy was performed using a needle knife sphincterotome. After a partial infundibulotomy, a dilation balloon was passed over a prepositioned guidewire and placed in the biliary orifice. Under endoscopic and fluoroscopic control, the balloon was then inflated with diluted contrast over a period of 1 to 2 minutes. RESULTS: A total of 10 patients (7 male and 3 female) were enrolled in this study. Eight had common bile duct stones, 1 bile duct cancer, and 1 pancreatic cancer. The common bile duct was dilated by a balloon. The calculi were removed in 6 patients, and a common bile duct stent was implanted in two cases via endoscopy. No complications such as acute pancreatitis or apparent infections of the biliary tracts were encountered in these cases except for mild fever, temporary high serum levels of aminotransferase and amylase after ERCP in 3 cases. No severe bleeding or perforation occurred in patients undergoing balloon dilatation. CONCLUSIONS: An infundibulotomy with balloon dilatation is a valuable alternative to endoscopic sphinterotomy in the treatment of patients with bile duct diseases, who have undergone prior Billroth II gastrectomies.

PURPOSE: This study was performed to improve cardiopulmonary resuscitation(CPR) training strategies for occupational groups, through the analysis of first responders' characteristics, knowledge and attitudes concerning CPR. METHODS: The occupational groups expected to have some training on rescue and emergency care in Korea were regarded as the first responders. In particular, this study focused on nurse-teachers, traffic policemen, and industrial safety supervisors, taxi drivers and restaurant workers as potential first responders, clerical workers comprised the control group. The subjects were given a questionnaire to answer over the internet. RESULTS: First responders' knowledge on CPR was significantly higher than that of the control group. First responders' attitude on CPR was more affirmative compared with the control group. In first responder group, nurse-teachers, traffic policemen and industrial safety supervisors had a higher fund of knowledge and more positive attitudes when compared to taxi drivers and restaurant workers. CONCLUSION: More training for first responders in CPR and emergency care is required given the likelihood of medical emergencies arising while on duty. Taxi drivers and restaurant workers' knowledge on CPR were found to be inadequate based on our survey questionnaire. Thus, it is necessary to strengthen CPR training for these individuals and groups.

Toluene is an aromatic hydrocarbon found in glues, cements, and solvents. Chronic or acute exposure is known to cause acid-base and electrolyte disorders and to be toxic to both the nervous system and the hematopoietic system. The three major clinical presentations involve neuropsychiatric, gastrointestinal, and muscular disorders, whereas toluene intoxication is difficult to diagnose without a history of substance abuse, such as glue sniffing. We report the case of a 27-year-old women who presented with the three major clinical manifestations associated with profound hypokalemia (K+=1 mEq/L) and metabolic acidosis (pH=7.17) after prolonged glue sniffing. To make an early diagnosis, the emergency physician should consider toluene intoxication in patients presenting with altered mental status, hypokalemic muscular paralysis, and a history of glue sniffing.

PURPOSE: This study was performed to compare the accuracy of noncontrast helical computerized tomography (NHCT) with that of intravenous pyelography (IVP) in the evaluation of urolithiasis in the emergency room (ER). METHODS: Between November 2003 and February 2004, a total of 47 consecutive patients presenting to the emergency department with acute flank pain were evaluated with NHCT followed by IVP. The mean of the time interval between NHCT and IVP was less than 5 minutes. All 47 sets of evaluations were later assessed randomly by an independent consulting radiologist for the presence, size, and location of a stone, ureteral dilatation, and secondary signs of ureteral obstruction. RESULTS: Forty-three of the 47 patients were diagnosed with urolithiasis. In 39 of the 43 patients diagnosed with ureteral calculi, the NHCT made the diagnosis. IVP made the diagnosis in 26 of the 43 patients. NHCT had a 90.7% sensitivity, 100% specificity, and 68% accuracy. Compared with IVP, using the McNemar test, NHCT was significantly better able to predict the presence of urolithiasis (p<0.001). CONCLUSIONS: Unnenhanced helical CT is superior to IVP in the demonstration of ureteral calculi in patients with suspected acute urolithiasis in the ER.
